  • Selenium: How to use stored value in a javascript comparison

    - by dstrube
    I've searched around for the answer to this and found lots of much more complicated questions, but none that gave me insight enough to figure this one out. What I'm doing: 1- open a page with a number that will probably be large 2- get the X Path to where that number is and store it to a variable 3- do a javascript to compare the above stored variable to see if it is bigger than 10, if so, set a new varaible to true; else false (because that is the default value) 4- verify the variable in #3 is true Sounds simple enough, no? Where it goes wrong: At step 3, comparing the variable from step #2 to 10 isn't allowed, at least not the way I'm writing it. Why? Details: <tr> <td>open</td> <td>http://www.google.com/search?hl=en&q=selenium+verifyEval</td> <td></td> </tr> <tr> <td>store</td> <td>/html/body/div[5]/div/p/b[3]</td> <td>resultCount</td> </tr> <tr> <td>storeEval</td> <td>var isMoreThan10 = new Boolean(); isMoreThan10 = (resultCount &gt; 10);</td> <td>isMoreThan10</td> </tr> <tr> <td>verifyExpression</td> <td>${isMoreThan10}</td> <td>true</td> </tr> I just thought of one possible workaround: Exapnd the javascript code to get the value there & assign it to a variable there so I'll be more likely to be able to use that variable in the javascript. Not sure exactly how that would be done- anyone wanna help with that? But surely there is be a better way, isn't there? I must be able to assign a value to a variable in Selenium, then in the next line use that variable in a javascript, right?

  • jar dependencies in android- no class definition found exception

    - by Dave.B
    I'm trying to use the gdata java client library on android and have managed a decent hack to get it working. However because the jar for gdata had some package discrepancies with android I had to import the source into my project. This source is dependent on the JavaMail API and the JavaBeans Activation Framework as specified here. My issue is that the JavaMail jar throws a class definition not found when seeking a class which is in the Activation Framework jar. A stack trace is listed below. I am working in Eclipse and have both jars in a lib folder and added to my build path. I'm not very experienced dealing with jars in a situation like this so any help or insight would be appreciated. 03-29 09:55:26.204: ERROR/AndroidRuntime(331): Uncaught handler: thread AsyncTask #3 exiting due to uncaught exception 03-29 09:55:26.215: ERROR/AndroidRuntime(331): java.lang.RuntimeException: An error occured while executing doInBackground() 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at android.os.AsyncTask$3.done(AsyncTask.java:200) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask.setException(FutureTask.java:124) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1068) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:561) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.lang.Thread.run(Thread.java:1096) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): Caused by: java.lang.NoClassDefFoundError: javax.activation.DataHandler 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at javax.mail.internet.MimeBodyPart.setContent(MimeBodyPart.java:684) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at com.google.gdata.data.media.MediaBodyPart.<init>(MediaBodyPart.java:95) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at com.google.gdata.data.media.MediaMultipart.<init>(MediaMultipart.java:126) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at com.google.gdata.client.media.MediaService.insert(MediaService.java:382) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at android.os.AsyncTask$2.call(AsyncTask.java:185) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305)

  • asp:Button is not calling server-side function

    - by Richard Neil Ilagan
    Hi guys, I know that there has been much discussion here about this topic, but none of the threads I got across helped me solve this problem. I'm hoping that mine is somewhat unique, and may actually merit a different solution. I'm instantiating an asp:Button inside a data-bound asp:GridView through template fields. Some of the buttons are supposed to call a server-side function, but for some weird reason, it doesn't. All the buttons do when you click them is fire a postback to the current page, doing nothing, effectively just reloading the page. Below is a fragment of the code: <asp:GridView ID="gv" runat="server" AutoGenerateColumns="false" CssClass="l2 submissions" ShowHeader="false"> <Columns> <asp:TemplateField> <ItemTemplate><asp:Panel ID="swatchpanel" CssClass='<%# Bind("status") %>' runat="server"></asp:Panel></ItemTemplate> <ItemStyle Width="50px" CssClass="sw" /> </asp:TemplateField> <asp:BoundField DataField="description" ReadOnly="true"> </asp:BoundField> <asp:BoundField DataField="owner" ReadOnly="true"> <ItemStyle Font-Italic="true" /> </asp:BoundField> <asp:BoundField DataField="last-modified" ReadOnly="true"> <ItemStyle Width="100px" /> </asp:BoundField> <asp:TemplateField> <ItemTemplate> <asp:Button ID="viewBtn" cssclass='<%# Bind("sid") %>' runat="server" Text="View" OnClick="viewBtnClick" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> The viewBtn above should call the viewBtnClick() function on server-side. I do have that function defined, along with a proper signature (object,EventArgs). One thing that may be of note is that this code is actually inside an ASCX, which is loaded in another ASCX, finally loaded into an ASPX. Any help or insight into the matter will be SO appreciated. Thanks! (oh, and please don't mind my trashy HTML/CSS semantics - this is still in a very,very early stage :p)

  • ZF-Autoloader not working in UnitTests on Ubuntu

    - by Sam
    i got a problem regarding Unit-testing a Zend-Framework application under Ubuntu 12.04. The project-structure is a default zend application whereas the models are defined as the following ./application ./models ./DbTable ./ProjectStatus.php (Application_Model_DbTable_ProjectStatus) ./Mappers ./ProjectStatus.php (Application_Model_Mapper_ProjectStatus) ./ProjectStatus.php (Application_Model_ProjectStatus) The Problem here is with the Zend-specific autoloading. The naming convention here appears that the folder Mappers loads all classes with _Mapper but not _Mappers. This is some internal Zend behavior which is fine so far. On my windows machine the phpunit runs without any Problems, trying to initiate all those classes. On my Ubuntu machine however with jenkins running on it, phpunit fails to find the appropriate classes giving me the following error Fatal error: Class 'Application_Model_Mapper_ProjectStatus' not found in /var/lib/jenkins/jobs/PAM/workspace/tests/application/models/Mapper/ProjectStatusTest.php on line 39 The error appears to really be that the Zend-Autoloader doesn't load from the ubuntu machine, but i can't figure out how or why this works. The question remains of why this is. I think i've double checked every point of contact with the zend autoloading stuff, but i just can't figure this out. I'll paste the - from my point of view relevant snippets - and hope someone of you has any insight to this. Jenkins Snippet for PHPUnit <target name="phpunit" description="Run unit tests with PHPUnit"> <exec executable="phpunit" failonerror="true"> <arg line="--configuration '${basedir}/tests/phpunit.xml' --coverage-clover '${basedir}/build/logs/clover.xml' --coverage-html '${basedir}/build/coverage/.' --log-junit '${basedir}/build/logs/junit.xml'" /> </exec> </target> ./tests/phpunit.xml <phpunit bootstrap="./bootstrap.php"> ... this shouldn't be of relevance ... </phpunit> ./tests/bootstrap.php <?php // Define path to application directory defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) .

  • jQuery function execute on Button Click and Enter/Return (key)

    - by Alvin Jones
    I'm trying to create a little search box that allows you to search Twitter based on the keyword you enter in the input field. While it's work, it only works if you press the Submit button. I would also like to be able to press the Enter or Return key to initiate the search. I've tried using the .sumbit function and wrapping my input around a form element with no success. Any insight would be greatly appreciate! Live example: http://tinyurl.com/84axyym <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <script> $(document).ready(function(){ function(data) { $('#startSearch').click(function(){ $('#tweets .results').remove(); var searchTerm = 'http://search.twitter.com/search.json?q=' + $('#twitterSearch').val() + '&callback=?' $.getJSON(searchTerm, function(data) { $.each(data.results, function() { $('<div class="results"></div>') .hide() .append('<a class="userPicLink" href="http://twitter.com/' + this.from_user + '">' + '<img class="userImg" src="' + this.profile_image_url + '">' + '</a>') .append('<span class="userName">' + '<a href="http://twitter.com/' + this.from_user + '">' + this.from_user + '</span>') .append('<span class="userText">' + this.text + '</span>') .append('<time class="textTime">' + relTime(this.created_at) + '</time>') .appendTo('#tweets') .fadeIn(); }); }); </script> <body> <label id="searchLabel" for="twitterSearch">Search</label> <input type="search" list="searchSugg" id="twitterSearch" placeholder="css3 animation" required aria-required="true"> <input id="startSearch" type="submit"> <datalist id="searchSugg"> <option value="css3 mulitple backgrounds"> <option value="html5 video"> <option value="responsive web design"> <option value="twitter api"> </datalist> <div id="tweets"> </div> </body>

  • File upload control - Select file is lossed when 2nd control is initiatied

    - by Barry
    Our problem/question revolves around an upload control that loses the selected file (goes blank) when a postback control is used (in this case, the dropdown list posts). Any insight into what we are doing wrong or how we can fix this? Below is our code and a summary of the problem. Any help would be greatly appreciated. Thank you! <asp:updatepanel id="UpdatePanel1" runat="server"> <ContentTemplate> <div class="row"> <asp:DropDownList runat="server" AutoPostBack="true" ID="CategorySelection" OnSelectedIndexChanged="CategorySelection_IndexChanged" CssClass="drop-down-list" /> </div> <div id="SubCategory" class="row" runat="server" visible="false"> <asp:DropDownList runat="server" ID="SubCategorySelection" CssClass="drop-down-list" /> </div> <div class="row"> <asp:FileUpload runat="server" ID="FileUpload" CssClass="file-upload" /> </div> <div class="row"> <asp:Button ID="submit" runat="server" Text="Submit" CssClass="button" OnClick="submit_ButtonClick" /> </div> </ContentTemplate> <Triggers> <asp:PostBackTrigger ControlID="submit" /> </Triggers> </asp:updatepanel> In this form we have 2 DropDownList, 1 FileUpload and 1 submit button. Every time that the user selects one category, the subcategories are loaded (AutoPostBack=”true”). The primary user flow works fine: User selects one category, subcategory and selects a file to be uploaded (submitted). HOWEVER, if the user selects a file first, and then selects a category, the screen will do a partial refresh and the selected file will disappear (field goes blank). As a result, the user needs to select the file again. This causes an issue because the fact that the file is no longer selected can easily be overlooked. Seems straighforward --- but causing us a lot of grief. Any experts out there that can help? BIG thanks!

  • jQuery image loop not displaying any images

    - by user1871097
    I'm trying to create a very basic image gallery in jQuery. The goal is to have 3 images fade in and out in a sequential order. So image 1 is displayed, fades to image 2 etc. then the whole thing loops again. My HTML code so far is as follows: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Slider</title> <style type="text/css"> .slider{ width: 2848px; height: 2136px; overflow: hidden; margin: 30px auto; } .slider img{ width:2848px; height:2136px; display:none; } </style> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script> <script src="Slider2.js"></script> </head> <body onload="Slider2"();> <div class="slider"> <img id="1" src="31.jpg" border="0" alt="city"/> <img id="2" src="2vrtigo2.jpg" border="0" alt="roof"/> <img id="3" src="3.jpg" border="0" alt="sea"/> </div> </body> And the jQuery code looks like this: function Slider2() { var total = $(".slider img").size(); for (i=1; i<=total; i+=1) { $(".slider #"+i).fadeIn(600); $(".slider #"+i).delay(2000).hide; }} A quick syntactical note, I've also tried using i++ in the last argument of the For Loop. The result of this code is a blank, white page. I know some of the HTML is being compiled because the enormous 2848x2136 div creates scroll bars on the browser. If anyone could help me out, that would be greatly appreciated. Obviously I'm relatively new to web programming and would love some insight into why this isn't working. Thanks!

  • Can't launch glassfish on ec2 - can't open port

    - by orange80
    I'm trying to start glassfish on an EBS-based AMI of Ubuntu 10.04 64-bit. I have used glassfish on non-ec2 servers with no problems, but on ec2 I get this message: $ sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server. Command start-domain failed. I know that ec2 has requires that firewall rules be modified using ec2-authorize to let outside traffic thru the firewall, as I had to do to make ssh work. This still doesn't explain the port error when all I'm trying to do is start glassfish so I can try $ wget localhost:8080and make sure it's working. This is very frustrating and I'd really appreciate any help. Thanks. FINAL UPDATE: Sorry if you came here looking for answers. I never figured out what was causing the problem. I created another fresh instance, installed the same stuff, and Glassfish worked perfectly. Something obviously got boned during installation, but I have no idea what. I guess it will remain a mystery. UPDATE: Here's what I get from netstat: # netstat -nuptl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 462/sshd tcp6 0 0 :::22 :::* LISTEN 462/sshd udp 0 0 0.0.0.0:5353 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:1194 0.0.0.0:* 589/openvpn udp 0 0 0.0.0.0:37940 0.0.0.0:* 483/avahi-daemon: r udp 0 0 0.0.0.0:68 0.0.0.0:* 377/dhclient3 UPDATE: One more thing... I know that the "net.ipv6.bindv6only" kernel option can cause problems with java networking, so I did set this: # sysctl -w net.ipv6.bindv6only=0 UPDATE: I also verified that it has nothing at all to do with the port number (4848). As you can see here, when I changed the admin-listener port in domain.xml to 4949, I get a similar message: # sudo -u glassfish bin/asadmin start-domain domain1 There is a process already using the admin port 4949 -- it probably is another instance of a GlassFish server. Command start-domain failed. UPDATE: Here are the contents of /etc/hosts: 127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts I should mention that I have another Ubuntu Lucid 10.04 64-bit slice that is NOT hosted on ec2, and set it up the exact same way with no problems whatsoever.

  • Cannot ping host stale ARP cache?

    - by gkchicago
    I am having a strange issue with a Debian (Lenny/Linux 2.6.26-2-amd64) that has been driving me nuts. On some machines within my network I can ping the host in question just fine, other times I have to manually hard-code the ARP ethernet address for the IP in order to establish connectivity. I've finally worked it down to somehow involving ARP. I just found how to fix it in a way that made it work but I'm looking for help explaining this issue and also I don't trust my fix to be permanent.. My thought process has been the following but I just can't make any sense out of it: Could it be the card? (Intel 82555 rev 4) Could it be because there are two network cards? (Default route is eth0) Could it be because of the network aliases? Lenny? AMD x86_64? Argh..

  • Diagnosing Solaris 8 server memory and swap space usage

    - by datSilencer
    Hello everyone. Essentially, my question is related to memory allocation for Solaris virtual machines. I am running a couple of old Sun ONE 6 Java web servers on two Solaris 8 virtual machines. I see that there's a reasonable amount of swap space being used, but I'm not exactly sure if this could indicate a need to add more RAM to these machines. At service peak hours (mornings usually), the response time of the web application these servers host jumps up to at most 11 seconds (somewhat detrimental for a relatively simple web page loading action). Average response time at non peak times is about 5 seconds. What would you be able to infer about the RAM usage for these machines from the ouput below? Is this information reasonably sufficient? Or would I need to run some other commands to rule out server memory starvation? Finally, since there is a Java application at the core of the setup, I've also thought about: 1) Trace the heap's Object allocation to detect potential memory leaks. 2) Do some performance profiling to see if this instead related to networking delays. I mention this since the application talks with a single Oracle Database, but I would doubt this to be the case since they're pretty close from a network segmentation perspective. I appreciate any kind of insight and feedback you could provide. Thanks for your time and help.

  • Netgear VPN endpoint drops connectivity to single IP address

    - by Justin Bowers
    I'm having a strange issue with one of the networks I manage recently. We have about 14 different networks connected together through a Netgear hardware VPN. Everything has been running fine (other than standard connectivity problems) for a few years now, but I've hit a wall with a problem that's just cropped up at one of the VPN endpoint locations. Our primary VPN network is on the 192.168.1.0/24 subnet and our other 13 networks are on the 192.168.2.0/24 - 192.168.14.0/24 subnets. We run a terminal server on the 192.168.1.0/24 network with IP address 192.168.1.100. Starting Thursday of last week, we had a problem with connectivity of the 192.168.2.0/24 network to 192.168.1.100. When troubleshooting the problem, I found that Network 2 (192.168.2.0/24) still had connectivity to the Internet as well as VPN connectivity to Network 1 (192.168.1.0/24). We could ping and connect to any other device other than the server with IP address 192.168.1.100. Also, none of our networks had an issue accessing 192.168.1.100. I ran a scan on Network 2 after assigning static IP addresses to one of the workstations but received no response from 192.168.1.100 (looking for possibly a new device that someone had plugged into Network 2 that had a duplicate IP address with the server). Asking the staff, noone had reported connecting a new device to Network 2 as well. I then assigned a secondary IP address of 192.168.1.88 to the server and could ping and connect to the secondary IP address from Network 2, but still couldn't access it via 192.168.1.100. I then just rebooted the Netgear VPN Firewall (FVS318v3) and after it came back up, connectivity to 192.168.1.100 was restored. Beforehand, when checking for devices with a possible duplicate IP address, I did run a check for available wireless access points and stations and found none (our wireless is secured via MAC address access control through a WG102 device). I thought that it may have been a fluke for some reason since everything came back up after a power cycle of the VPN Firewall. Things ran fine for a few days until this afternoon, when the problem happened again. One of our users claimed that they had connectivity problems to the server and after connecting to the computer, I found that I couldn't ping the server address anymore. I could still ping the alternate IP address of the server though, so I went ahead and rebooted the VPN firewall again and connectivity was restored. Unfortunately, I can't find anything in the security or VPN logs of the firewall that helps point me in the right direction, so I thought I would go ahead and ask to see if anyone else has any other insight into why we've started having this problem. I am aware that it could still be a device with a duplicate IP address of the server on Network 2, but every employee claim states that there's been no such new device brought in to the network. I know this is a long read, but any help is appreciated! Thanks, Justin

  • How clean is deleting a computer object?

    - by Kevin
    Though quite skilled at software development, I'm a novice when it comes to Active Directory. I've noticed that AD seems to have a lot of stuff buried in the directory and schema which does not appear superficially when using simplified tools such as Active Directory Users and Computers. It kind of feels like the Windows registry, where COM classes have all kinds of intertwined references, many of which are purely by GUID, such that it's not enough to just search for anything referencing "GadgetXyz" by name in order to cleanly remove GadgetXyz. This occasionally leads to the uneasy feeling that I may have useless garbage building up in there which I have no idea how to weed out. For instance, I made the mistake a while back of trying to rename a DC, figuring I could just do it in the usual manner from Control Panel. I found references to the old name buried all over the place which made it impossible to reuse that name without considerable manual cleanup. Even long after I got it all working, I've stumbled upon the old name hidden away in LDAP. (There were no other DCs left in the picture at that time so I don't think it was a tombstone issue.) More specifically, I'm worried about the case of just outright deleting a computer from AD. I understand the cleanest way to do it is to log into the computer itself and tell it to leave the domain. (As an aside, doing this in Windows 8 seems to only disable the computer object and not delete it outright!) My concern is cases where this is not possible, for instance because it was on an already-deleted VM image. I can simply go into Active Directory Users and Computers, find the computer object, click it, and press Delete, and it seems to go away. My question is, is it totally, totally gone, or could this leave hanging references in any Active Directory nook or cranny I won't know to look in? (Excluding of course the expected tombstone records which expire after a set time.) If so, is there any good way to clean up the mess? Thank you for any insight! Kevin ps., It was over a year ago so I don't remember the exact details, but here's the gist of the DC renaming issue. I started with a single 2008 DC named ABC in a physical machine and wanted to end up instead with a DC of the same name running in a vSphere VM. Not wanting to mess with imaging the physical machine, my plan instead was: Rename ABC to XYZ. Fresh install 2008 on a VM, name it ABC, and join it to the domain. (I may have done the latter in the same step as promoting to DC; I don't recall.) dcpromo the new ABC as a 2nd DC, including GC. Make sure the new ABC replicated correctly from XYZ and then transfer the FSMO roles from XYZ to it. Once everything was confirmed to work with the new ABC alone, demote XYZ, remove the AD role, and remove it from the domain. Eventually I managed to do this but it was a much bumpier ride than expected. In particular, I got errors trying to join the new ABC to the domain. These included "The pre-windows 2000 name is already in use" and "No mapping between account names and security IDs was done." I eventually found that the computer object for XYZ had attributes that still referred to it as ABC. Among these were servicePrincipalName, msDS-AdditionalDnsHostName, and msDS-AdditionalSamAccountName. The latter I could not edit via Attribute Editor and instead had to run this against XYZ: NETDOM computername <simple-name> /add:<FQDN> There were some other hitches I don't remember exactly.

  • Windows 7 / Ubuntu Dualboot GRUB Problem.

    - by Tek
    I'd like to first say ahead of time that I'm running a RAID-0 Setup. 1.First of all, I'm glad Ubuntu 9.10 installed flawlessly and detected my RAID-0 setup just fine. The issue I'm having now is that I already had Windows 7 installed and made a small 12GB partition for Linux/Swap. I grabbed EasyBCD 2.0 to edit the W7 bootloader and configured it to use dual boot Grub2 because before it didn't even show the option for Ubuntu. The bootloader points to a file made in the windows directory made by EasyBCD called "C:\NST\AutoNeoGrub0.mbr" which is what I'm guessing grub is booting from. After that I got the option for booting Ubuntu. The problem is that it's sending me to the Grub prompt (probably because it's pointing to \NST|AutoNeoGrub0.mbr?), at first I didn't know what to do but I researched and have to type grub commands to manually boot into Ubuntu Linux. Ex: grubroot (hd0,4) grubkernel /boot/vmlinuz-2.6... root=/dev/disk/by-uuid/24624-2424... grubinitrd boot/initrd.img-2.6... grubboot After all that Ubuntu boots just fine, but how do I fix it permanently? Do I need to edit the bootloader manually (since Easy BCD "autoconfigures")? Some insight on this would rock! Also, it sucks to type the actual uuid since it's REALLY long. I tried getting the name of the drive via fdisk -l but since it's raid 0 I'm guessing I can't do that. How can I get a shorter name of the drive? like /dev/sda, /dev/sdb etc? I've also tried to update to the latest GRUB and I got this: Creating config file /etc/default/grub with new version Generating core.img error: cannot seek /dev/sdc' error: cannot seek/dev/sdc' grub-probe: error: no mapping exists for nvidia_dbedfcca5' Auto-detection of a filesystem module failed.

  • Alternative Methods of Sharing Folders in Windows?

    - by Blaenk
    Hey guys. I'm running Windows 7 and as of now I simply share folders as one usually does in Windows. I then have a MacBook with Leopard (Now Snow Leopard) which I use to connect to my computer to mount the shares by going to Finder, then CMD + K and typing smb://BlaenkPC (The name of my PC) into the address box. This consequently connects to my computer and mounts all of the shares. The problem is that sometimes, if for example I close my MacBook (Which makes it go to sleep) or sometimes even without doing that, the connection somehow drops. Sometimes I close the MacBook and upon re-opening it, everything still works; it's random. It still shows the computer as being connected, but it just shows 'loading' indefinitely. If I hit 'eject' with the intention of re-connecting to the computer, it disappears from the sidebar (The Computer Icon) in Finder, but I cannot re-connect. Activity Monitor (or ps aux, whichever) both show hung instances of umount; one for each share that was mounted. I cannot kill these processes with kill or killall (Yes, even with sudo, and sending signal -9). This has happened to me before, and here is another person who has experienced this. My question boils down to this: Is there an alternative method of sharing folders in Windows, that my Mac can read/understand, that is possibly more reliable and preferably just as fast? I usually use the mounted shares to watch television episodes off my computer, or movies, etc. (In other words, I open them in VLC and they automatically stream from my computer). As far as I can tell, this is a problem with the Samba protocol. I have heard of NFS, but I am not sure if I would have to re-format my drives, or what. I don't mind running a service or daemon to allow the sharing of the folders, I just want it to be done and hopefully in a better way than typical Windows shares through Samba. Usually when I encounter this problem, which is often (read: every day), I have no other option but to restart the MacBook. As I stated in the first question I linked to, shutting down and restarting don't work; I have to manually force the shutdown by holding the power button. I have not modified my installation of Mac OS X in any hackish way, so I doubt it's something with the Operating System, but worst come to worst, I might end up reformatting and doing a clean install to see if that fixes anything, as I am at a complete loss as to what may be causing the problem, and no one else seems to have any idea or care, despite there being quite a few people suffering from this problem, as my research has shown. Any pieces of information that can help are extremely appreciated. You don't have to answer every question on here, but maybe even some insight as to why it might not be possible to kill those hung umount instances for example, or why I may not be able to reconnect using samba (Is it something regarding the way the protocol works?). One thing to note is that I have another computer in the home network that doesn't seem to have this problem. However, it is also running Windows 7 (Note though that I am not using the homegroup feature, but the typical windows sharing feature). My only deduction is that the problem is being caused by the way the Mac (Or Samba implementation, whichever) is handling things. Perhaps it is a limitation.

  • How to install Delorme StreetAtlas (any version) + GPS inside VirtualBox VM?

    - by hotei
    When I try to run the install program I get a popup message that says the installer program is not a valid executable. Background: I want a GPS with maps on my laptop running Ubuntu 10.4LTS. Unfortunately I can't find a decent native Linux GPS solution with 50 state US street level coverage. I have VirtualBox VMs available for WinXP and Win7 (among others). The VMs work fine with MicroSoft Streets and Trips (2010) and MapNGo 5 (a very! old Delorme product), but while both these products support GPS, they don't support the Earthmate LT-40 USB GPS I already have. I've got pretty much every Delorme Street Atlas they've released in the last decade and none of them will install in a VM. Any help would be much appreciated. Clarification: I've installed the Delorme products from these CDs before and the disks are fine - as long as installation is done on a "physical" machine. Added: I've tried install from an iso as well as the real CD. No difference in result (setup.exe is not a valid executable) The WinXP is SP-2 (held back on purpose at this point - I'll snapshot and fork a later SP to test). The Win2K is SP-6a. Win7(32) VM is whatever updates came out last week. The USB setup is working at least to the point where the GPS device is active in the device list (has an x in the box). At this point its not relevant because the program that needs to read it can't even be installed. Added 9-19: Added wine as harrymc suggested. Initial result was no change. Here's wines error message. The file '/media/Disk1/setup.exe' is not marked as executable. If this was downloaded or copied form an untrusted source, it may be dangerous to run. For more details, read about the executable bit. At first I thought the execute bit was the problem, but looking at several other windows CDs I see that the execute bit is not set on their exe files (which install to VM without error). Still it was worth a shot so I copied the StreetAtlas 9 DVD to my hard disk, changed the on-disk exe files to have the execute bit set and tried to install again. This time the install via wine got me through the installation process. When I start the program it bombs immediately, so we haven't made much real progress so far. I very much prefer the VM solution to wine, so I'm going back to that for now. To recap the VM situation, using an updated XP with SP3 and all recommended hotfixes: StreetAtlas 2009 USA fails with "not marked as executable". StreetAtlas 2007 USA fails with "not marked as executable". StreetAtlas 9 (copyright 2001) fails with "not marked as executable". SteeetAtlas (copyright 1991) fails with "not marked as executable" Delorme Topo 4 (copyright 2002) fails with "not marked as executable". Just about ready to give up. So I switched from XP VM to Win7 VM and tried StreetAtlas 2009 again. This time it installs. Earthmate USB GPS works. WTH? I feel like the monkey who just wrote a line of Shakespear. I'm smiling because it worked, but I have no clue why. I'm awarding the bounty to harrymc because wine did give some useful insight into the problem and a +1 to goyiux as thanks for helping.

  • Network config / gear question

    - by mcgee1234
    I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

  • Top 10 Reasons SQL Developer is Perfect for Oracle Beginners

    - by thatjeffsmith
    Learning new technologies can be daunting. If you’ve never used a Mac before, you’ll probably be a bit baffled at first. But, you’re probably at least coming from a desktop computing background (Windows), so you common frame of reference. But what if you’re just now learning to use a relational database? Yes, you’ve played with Access a bit, but now your employer or college instructor has charged you with becoming proficient with Oracle database. Here’s 10 reasons why I think Oracle SQL Developer is the perfect vehicle to help get you started. 1. It’s free No need to break into one of these… No start-up costs, no need to wrangle budget dollars from your company. Students don’t have any money after books and lab fees anyway. And most employees don’t like having to ask for ‘special’ software anyway. So avoid all of that and make sure the free stuff doesn’t suit your needs first. Upgrades are available on a regular base, also at no cost, and support is freely available via our public forums. 2. It will run pretty much anywhere Windows – check. OSX (Apple) – check. Unix – check. Linux – check. No need to start up a windows VM to run your Windows-only software in your lab machine. 3. Anyone can install it There’s no installer, no registry to be updated, no admin privs to be obtained. If you can download and extract files to your machine or USB storage device, you can run it. You can be up and running with SQL Developer in under 5 minutes. Here’s a video tutorial to see how to get started. 4. It’s ubiquitous I admit it, I learned a new word yesterday and I wanted an excuse to use it. SQL Developer’s everywhere. It’s had over 2,500,000 downloads in the past year, and is the one of the most downloaded items from OTN. This means if you need help, there’s someone sitting nearby you that can assist, and since they’re in the same tool as you, they’ll be speaking the same language. 5. Simple User Interface Up-up-down-down-Left-right-left-right-A-B-A-B-START will get you 30 lives, but you already knew that, right? You connect, you see your objects, you click on your objects. Or, you can use the worksheet to write your queries and programs in. There’s only one toolbar, and just a few buttons. If you’re like me, video games became less fun when each button had 6 action items mapped to it. I just want the good ole ‘A’, ‘B’, ‘SELECT’, and ‘START’ controls. If you’re new to Oracle, you shouldn’t have the double-workload of learning a new complicated tool as well. 6. It’s not a ‘black box’ Click through your objects, but also get the SQL that drives the GUI As you use the wizards to accomplish tasks for you, you can view the SQL statement being generated on your behalf. Just because you have a GUI, doesn’t mean you’re ceding your responsibility to learn the underlying code that makes the database work. 7. It’s four tools in one It’s not just a query tool. Maybe you need to design a data model first? Or maybe you need to migrate your Sybase ASE database to Oracle for a new project? Or maybe you need to create some reports? SQL Developer does all of that. So once you get comfortable with one part of the tool, the others will be much easier to pick up as your needs change. 8. Great learning resources available Videos, blogs, hands-on learning labs – you name it, we got it. Why wait for someone to train you, when you can train yourself at your own pace? 9. You can use it to teach yourself SQL Instead of being faced with the white-screen-of-panic, you can visually build your queries by dragging and dropping tables and views into the Query Builder. Yes, ‘just like Access’ – only better. And as you build your query, toggle to the Worksheet panel and see the SQL statement. Again, SQL Developer is not a black box. If you prefer to learn by trial and error, the worksheet will attempt to suggest the next bit of your SQL statement with it’s completion insight feature. And if you have syntax errors, those will be highlighted – just like your misspelled words in your favorite word processor. 10. It scales to match your experience level You won’t be a n00b forever. In 6-8 months, when you’re ready to tackle something a bit more complicated, like XML DB or Oracle Spatial, the tool is already there waiting on you. No need to go out and find the ‘advanced’ tool. 11. Wait, you said this was a ‘Top 10′ list? Yes. Yes, I did. I’m using this ‘trick’ to get you to continue reading because I’m going to say something you might not want to hear. Are you ready? Tools won’t replace experience, failure, hard work, and training. Just because you have the keys to the car, doesn’t mean you’re ready to head out on the race track. While SQL Developer reduces the barriers to entry, it does not completely remove them. Many experienced folks simply do not like tools. Rather, they don’t like the people that pick up tools without the know-how to properly use them. If you don’t understand what ‘TRUNCATE’ means, don’t try it out. Try picking up a book first. Of course, it’s very nice to have your own sandbox to play in, so you don’t upset the other children. That’s why I really like our Dev Days Database Virtual Box image. It’s your own database to learn and experiment with.

  • Oracle Data Mining a Star Schema: Telco Churn Case Study

    - by charlie.berger
    There is a complete and detailed Telco Churn case study "How to" Blog Series just posted by Ari Mozes, ODM Dev. Manager.  In it, Ari provides detailed guidance in how to leverage various strengths of Oracle Data Mining including the ability to: mine Star Schemas and join tables and views together to obtain a complete 360 degree view of a customer combine transactional data e.g. call record detail (CDR) data, etc. define complex data transformation, model build and model deploy analytical methodologies inside the Database  His blog is posted in a multi-part series.  Below are some opening excerpts for the first 3 blog entries.  This is an excellent resource for any novice to skilled data miner who wants to gain competitive advantage by mining their data inside the Oracle Database.  Many thanks Ari! Mining a Star Schema: Telco Churn Case Study (1 of 3) One of the strengths of Oracle Data Mining is the ability to mine star schemas with minimal effort.  Star schemas are commonly used in relational databases, and they often contain rich data with interesting patterns.  While dimension tables may contain interesting demographics, fact tables will often contain user behavior, such as phone usage or purchase patterns.  Both of these aspects - demographics and usage patterns - can provide insight into behavior.Churn is a critical problem in the telecommunications industry, and companies go to great lengths to reduce the churn of their customer base.  One case study1 describes a telecommunications scenario involving understanding, and identification of, churn, where the underlying data is present in a star schema.  That case study is a good example for demonstrating just how natural it is for Oracle Data Mining to analyze a star schema, so it will be used as the basis for this series of posts...... Mining a Star Schema: Telco Churn Case Study (2 of 3) This post will follow the transformation steps as described in the case study, but will use Oracle SQL as the means for preparing data.  Please see the previous post for background material, including links to the case study and to scripts that can be used to replicate the stages in these posts.1) Handling missing values for call data recordsThe CDR_T table records the number of phone minutes used by a customer per month and per call type (tariff).  For example, the table may contain one record corresponding to the number of peak (call type) minutes in January for a specific customer, and another record associated with international calls in March for the same customer.  This table is likely to be fairly dense (most type-month combinations for a given customer will be present) due to the coarse level of aggregation, but there may be some missing values.  Missing entries may occur for a number of reasons: the customer made no calls of a particular type in a particular month, the customer switched providers during the timeframe, or perhaps there is a data entry problem.  In the first situation, the correct interpretation of a missing entry would be to assume that the number of minutes for the type-month combination is zero.  In the other situations, it is not appropriate to assume zero, but rather derive some representative value to replace the missing entries.  The referenced case study takes the latter approach.  The data is segmented by customer and call type, and within a given customer-call type combination, an average number of minutes is computed and used as a replacement value.In SQL, we need to generate additional rows for the missing entries and populate those rows with appropriate values.  To generate the missing rows, Oracle's partition outer join feature is a perfect fit.  select cust_id, cdre.tariff, cdre.month, minsfrom cdr_t cdr partition by (cust_id) right outer join     (select distinct tariff, month from cdr_t) cdre     on (cdr.month = cdre.month and cdr.tariff = cdre.tariff);   ....... Mining a Star Schema: Telco Churn Case Study (3 of 3) Now that the "difficult" work is complete - preparing the data - we can move to building a predictive model to help identify and understand churn.The case study suggests that separate models be built for different customer segments (high, medium, low, and very low value customer groups).  To reduce the data to a single segment, a filter can be applied: create or replace view churn_data_high asselect * from churn_prep where value_band = 'HIGH'; It is simple to take a quick look at the predictive aspects of the data on a univariate basis.  While this does not capture the more complex multi-variate effects as would occur with the full-blown data mining algorithms, it can give a quick feel as to the predictive aspects of the data as well as validate the data preparation steps.  Oracle Data Mining includes a predictive analytics package which enables quick analysis. begin  dbms_predictive_analytics.explain(   'churn_data_high','churn_m6','expl_churn_tab'); end; /select * from expl_churn_tab where rank <= 5 order by rank; ATTRIBUTE_NAME       ATTRIBUTE_SUBNAME EXPLANATORY_VALUE RANK-------------------- ----------------- ----------------- ----------LOS_BAND                                      .069167052          1MINS_PER_TARIFF_MON  PEAK-5                   .034881648          2REV_PER_MON          REV-5                    .034527798          3DROPPED_CALLS                                 .028110322          4MINS_PER_TARIFF_MON  PEAK-4                   .024698149          5From the above results, it is clear that some predictors do contain information to help identify churn (explanatory value > 0).  The strongest uni-variate predictor of churn appears to be the customer's (binned) length of service.  The second strongest churn indicator appears to be the number of peak minutes used in the most recent month.  The subname column contains the interior piece of the DM_NESTED_NUMERICALS column described in the previous post.  By using the object relational approach, many related predictors are included within a single top-level column. .....   NOTE:  These are just EXCERPTS.  Click here to start reading the Oracle Data Mining a Star Schema: Telco Churn Case Study from the beginning.

  • Learning AngularJS by Example – The Customer Manager Application

    - by dwahlin
    I’m always tinkering around with different ideas and toward the beginning of 2013 decided to build a sample application using AngularJS that I call Customer Manager. It’s not exactly the most creative name or concept, but I wanted to build something that highlighted a lot of the different features offered by AngularJS and how they could be used together to build a full-featured app. One of the goals of the application was to ensure that it was approachable by people new to Angular since I’ve never found overly complex applications great for learning new concepts. The application initially started out small and was used in my AngularJS in 60-ish Minutes video on YouTube but has gradually had more and more features added to it and will continue to be enhanced over time. It’ll be used in a new “end-to-end” training course my company is working on for AngularjS as well as in some video courses that will be coming out. Here’s a quick look at what the application home page looks like: In this post I’m going to provide an overview about how the application is organized, back-end options that are available, and some of the features it demonstrates. I’ve already written about some of the features so if you’re interested check out the following posts: Building an AngularJS Modal Service Building a Custom AngularJS Unique Value Directive Using an AngularJS Factory to Interact with a RESTful Service Application Structure The structure of the application is shown to the right. The  homepage is index.html and is located at the root of the application folder. It defines where application views will be loaded using the ng-view directive and includes script references to AngularJS, AngularJS routing and animation scripts, plus a few others located in the Scripts folder and to custom application scripts located in the app folder. The app folder contains all of the key scripts used in the application. There are several techniques that can be used for organizing script files but after experimenting with several of them I decided that I prefer things in folders such as controllers, views, services, etc. Doing that helps me find things a lot faster and allows me to categorize files (such as controllers) by functionality. My recommendation is to go with whatever works best for you. Anyone who says, “You’re doing it wrong!” should be ignored. Contrary to what some people think, there is no “one right way” to organize scripts and other files. As long as the scripts make it down to the client properly (you’ll likely minify and concatenate them anyway to reduce bandwidth and minimize HTTP calls), the way you organize them is completely up to you. Here’s what I ended up doing for this application: Animation code for some custom animations is located in the animations folder. In addition to AngularJS animations (which are defined using CSS in Content/animations.css), it also animates the initial customer data load using a 3rd party script called GreenSock. Controllers are located in the controllers folder. Some of the controllers are placed in subfolders based upon the their functionality while others are placed at the root of the controllers folder since they’re more generic:   The directives folder contains the custom directives created for the application. The filters folder contains the custom filters created for the application that filter city/state and product information. The partials folder contains partial views. This includes things like modal dialogs used in the application. The services folder contains AngularJS factories and services used for various purposes in the application. Most of the scripts in this folder provide data functionality. The views folder contains the different views used in the application. Like the controllers folder, the views are organized into subfolders based on their functionality:   Back-End Services The Customer Manager application (grab it from Github) provides two different options on the back-end including ASP.NET Web API and Node.js. The ASP.NET Web API back-end uses Entity Framework for data access and stores data in SQL Server (LocalDb). The other option on the back-end is Node.js, Express, and MongoDB.   Using the ASP.NET Web API Back-End To run the application using ASP.NET Web API/SQL Server back-end open the .sln file at the root of the project in Visual Studio 2012 or higher (the free Express 2013 for Web version is fine). Press F5 and a browser will automatically launch and display the application. Using the Node.js Back-End To run the application using the Node.js/MongoDB back-end follow these steps: In the CustomerManager directory execute 'npm install' to install Express, MongoDB and Mongoose (package.json). Load sample data into MongoDB by performing the following steps: Execute 'mongod' to start the MongoDB daemon Navigate to the CustomerManager directory (the one that has initMongoCustData.js in it) then execute 'mongo' to start the MongoDB shell Enter the following in the mongo shell to load the seed files that handle seeding the database with initial data: use custmgr load("initMongoCustData.js") load("initMongoSettingsData.js") load("initMongoStateData.js") Start the Node/Express server by navigating to the CustomerManager/server directory and executing 'node app.js' View the application at http://localhost:3000 in your browser. Key Features The Customer Manager application certainly doesn’t cover every feature provided by AngularJS (as mentioned the intent was to keep it as simple as possible) but does provide insight into several key areas: Using factories and services as re-useable data services (see the app/services folder) Creating custom directives (see the app/directives folder) Custom paging (see app/views/customers/customers.html and app/controllers/customers/customersController.js) Custom filters (see app/filters) Showing custom modal dialogs with a re-useable service (see app/services/modalService.js) Making Ajax calls using a factory (see app/services/customersService.js) Using Breeze to retrieve and work with data (see app/services/customersBreezeService.js). Switch the application to use the Breeze factory by opening app/services.config.js and changing the useBreeze property to true. Intercepting HTTP requests to display a custom overlay during Ajax calls (see app/directives/wcOverlay.js) Custom animations using the GreenSock library (see app/animations/listAnimations.js) Creating custom AngularJS animations using CSS (see Content/animations.css) JavaScript patterns for defining controllers, services/factories, directives, filters, and more (see any JavaScript file in the app folder) Card View and List View display of data (see app/views/customers/customers.html and app/controllers/customers/customersController.js) Using AngularJS validation functionality (see app/views/customerEdit.html, app/controllers/customerEditController.js, and app/directives/wcUnique.js) More… Conclusion I’ll be enhancing the application even more over time and welcome contributions as well. Tony Quinn contributed the initial Node.js/MongoDB code which is very cool to have as a back-end option. Access the standard application here and a version that has custom routing in it here. Additional information about the custom routing can be found in this post.

  • Another Marketing Conference, part two – the afternoon

    - by Roger Hart
    In my previous post, I’ve covered the morning sessions at AMC2012. Here’s the rest of the write-up. I’ve skipped Charles Nixon’s session which was a blend of funky futurism and professional development advice, but you can see his slides here. I’ve also skipped the Google presentation, as it was a little thin on insight. 6 – Brand ambassadors: Getting universal buy in across the organisation, Vanessa Northam Slides are here This was the strongest enforcement of the idea that brand and campaign values need to be delivered throughout the organization if they’re going to work. Vanessa runs internal communications at e-on, and shared her experience of using internal comms to align an organization and thereby get the most out of a campaign. She views the purpose of internal comms as: “…to help leaders, to communicate the purpose and future of an organization, and support change.” This (and culture) primes front line staff, which creates customer experience and spreads brand. You ensure a whole organization knows what’s going on with both internal and external comms. If everybody is aligned and informed, if everybody can clearly articulate your brand and campaign goals, then you can turn everybody into an advocate. Alignment is a powerful tool for delivering a consistent experience and message. The pathological counter example is the one in which a marketing message goes out, which creates inbound customer contacts that front line contact staff haven’t been briefed to handle. The NatWest campaign was again mentioned in this context. The good example was e-on’s cheaper tariff campaign. Building a groundswell of internal excitement, and even running an internal launch meant everyone could contribute to a good customer experience. They found that meter readers were excited – not a group they’d considered as obvious in providing customer experience. But they were a group that has a lot of face-to-face contact with customers, and often were asked questions they may not have been briefed to answer. Being able to communicate a simple new message made it easier for them, and also let them become a sales and marketing asset to the organization. 7 – Goodbye Internet, Hello Outernet: the rise and rise of augmented reality, Matt Mills I wasn’t going to write this up, because it was essentially a sales demo for Aurasma. But the technology does merit some discussion. Basically, it replaces QR codes with visual recognition, and provides a simple-looking back end for attaching content. It’s quite sexy. But here’s my beef with it: QR codes had a clear visual language – when you saw one you knew what it was and what to do with it. They were clunky, but they had the “getting started” problem solved out of the box once you knew what you were looking at. However, they fail because QR code reading isn’t native to the platform. You needed an app, which meant you needed to know to download one. Consequentially, you can’t use QR codes with and ubiquity, or depend on them. This means marketers, content providers, etc, never pushed them, and they remained and awkward oddity, a minority sport. Aurasma half solves problem two, and re-introduces problem one, making it potentially half as useful as a QR code. It’s free, and you can apparently build it into your own apps. Add to that the likelihood of it becoming native to the platform if it takes off, and it may have legs. I guess we’ll see. 8 – We all need to code, Helen Mayor Great title – good point. If there was anybody in the room who didn’t at least know basic HTML, and if Helen’s presentation inspired them to learn, that’s fantastic. However, this was a half hour sales pitch for a basic coding training course. Beyond advocating coding skills it contained no useful content. Marketers may also like to consider some of these resources if they’re looking to learn code: Code Academy – free interactive tutorials Treehouse – learn web design, web dev, or app dev WebPlatform.org – tutorials and documentation for web tech  11 – Understanding our inner creativity, Margaret Boden This session was the most theoretical and probably least actionable of the day. It also held my attention utterly. Margaret spoke fluently, fascinatingly, without slides, on the subject of types of creativity and how they work. It was splendid. Yes, it raised a wry smile whenever she spoke of “the content of advertisements” and gave an example from 1970s TV ads, but even without the attempt to meet the conference’s theme this would have been thoroughly engaging. There are, Margaret suggested, three types of creativity: Combinatorial creativity The most common form, and consisting of synthesising ideas from existing and familiar concepts and tropes. Exploratory creativity Less common, this involves exploring the limits and quirks of a particular constraint or style. Transformational creativity This is uncommon, and arises from finding a way to do something that the existing rules would hold to be impossible. In essence, this involves breaking one of the constraints that exploratory creativity is composed from. Combinatorial creativity, she suggested, is particularly important for attaching favourable ideas to existing things. As such is it probably worth developing for marketing. Exploratory creativity may then come into play in something like developing and optimising an idea or campaign that now has momentum. Transformational creativity exists at the edges of this exploration. She suggested that products may often be transformational, but that marketing seemed unlikely to in her experience. This made me wonder about Listerine. Crucially, transformational creativity is characterised by there being some element of continuity with the strictures of previous thinking. Once it has happened, there may be  move from a revolutionary instance into an explored style. Again, from a marketing perspective, this seems to chime well with the thinking in Youngme Moon’s book: Different Talking about the birth of Modernism is visual art, Margaret pointed out that transformational creativity has historically risked a backlash, demanding what is essentially an education of the market. This is best accomplished by referring back to the continuities with the past in order to make the new familiar. Thoughts The afternoon is harder to sum up than the morning. It felt less concrete, and was troubled by a short run of poor presentations in the middle. Mainly, I found myself wrestling with the internal comms issue. It’s one of those things that seems astonishingly obvious in hindsight, but any campaign – particularly any large one – is doomed if the people involved can’t believe in it. We’ve run things here that haven’t gone so well, of course we have; who hasn’t? I’m not going to air any laundry, but people not being informed (much less aligned) feels like a common factor. It’s tough though. Managing and anticipating information needs across an organization of any size can’t be easy. Even the simple things like ensuring sales and support departments know what’s in a product release, and what messages go with it are easy to botch. The thing I like about framing this as a brand and campaign advocacy problem is that it makes it likely to get addressed. Better is always sexier than less-worse. Any technical communicator who’s ever felt crowded out by a content strategist or marketing copywriter  knows this – increasing revenue gets a seat at the table far more readily than reducing support costs, even if the financial impact is identical. So that’s it from AMC. The big thought-provokers were social buying behaviour and eliciting behaviour change, and the value of internal communications in ensuring successful campaigns and continuity of customer experience. I’ll be chewing over that for a while, and I’d definitely return next year.

  • Big Data&rsquo;s Killer App&hellip;

    - by jean-pierre.dijcks
    Recently Keith spent  some time talking about the cloud on this blog and I will spare you my thoughts on the whole thing. What I do want to write down is something about the Big Data movement and what I think is the killer app for Big Data... Where is this coming from, ok, I confess... I spent 3 days in cloud land at the Cloud Connect conference in Santa Clara and it was quite a lot of fun. One of the nice things at Cloud Connect was that there was a track dedicated to Big Data, which prompted me to some extend to write this post. What is Big Data anyways? The most valuable point made in the Big Data track was that Big Data in itself is not very cool. Doing something with Big Data is what makes all of this cool and interesting to a business user! The other good insight I got was that a lot of people think Big Data means a single gigantic monolithic system holding gazillions of bytes or documents or log files. Well turns out that most people in the Big Data track are talking about a lot of collections of smaller data sets. So rather than thinking "big = monolithic" you should be thinking "big = many data sets". This is more than just theoretical, it is actually relevant when thinking about big data and how to process it. It is important because it means that the platform that stores data will most likely consist out of multiple solutions. You may be storing logs on something like HDFS, you may store your customer information in Oracle and you may store distilled clickstream information in some distilled form in MySQL. The big question you will need to solve is not what lives where, but how to get it all together and get some value out of all that data. NoSQL and MapReduce Nope, sorry, this is not the killer app... and no I'm not saying this because my business card says Oracle and I'm therefore biased. I think language is important, but as with storage I think pragmatic is better. In other words, some questions can be answered with SQL very efficiently, others can be answered with PERL or TCL others with MR. History should teach us that anyone trying to solve a problem will use any and all tools around. For example, most data warehouses (Big Data 1.0?) get a lot of data in flat files. Everyone then runs a bunch of shell scripts to massage or verify those files and then shoves those files into the database. We've even built shell script support into external tables to allow for this. I think the Big Data projects will do the same. Some people will use MapReduce, although I would argue that things like Cascading are more interesting, some people will use Java. Some data is stored on HDFS making Cascading the way to go, some data is stored in Oracle and SQL does do a good job there. As with storage and with history, be pragmatic and use what fits and neither NoSQL nor MR will be the one and only. Also, a language, while important, does in itself not deliver business value. So while cool it is not a killer app... Vertical Behavioral Analytics This is the killer app! And you are now thinking: "what does that mean?" Let's decompose that heading. First of all, analytics. I would think you had guessed by now that this is really what I'm after, and of course you are right. But not just analytics, which has a very large scope and means many things to many people. I'm not just after Business Intelligence (analytics 1.0?) or data mining (analytics 2.0?) but I'm after something more interesting that you can only do after collecting large volumes of specific data. That all important data is about behavior. What do my customers do? More importantly why do they behave like that? If you can figure that out, you can tailor web sites, stores, products etc. to that behavior and figure out how to be successful. Today's behavior that is somewhat easily tracked is web site clicks, search patterns and all of those things that a web site or web server tracks. that is where the Big Data lives and where these patters are now emerging. Other examples however are emerging, and one of the examples used at the conference was about prediction churn for a telco based on the social network its members are a part of. That social network is not about LinkedIn or Facebook, but about who calls whom. I call you a lot, you switch provider, and I might/will switch too. And that just naturally brings me to the next word, vertical. Vertical in this context means per industry, e.g. communications or retail or government or any other vertical. The reason for being more specific than just behavioral analytics is that each industry has its own data sources, has its own quirky logic and has its own demands and priorities. Of course, the methods and some of the software will be common and some will have both retail and service industry analytics in place (your corner coffee store for example). But the gist of it all is that analytics that can predict customer behavior for a specific focused group of people in a specific industry is what makes Big Data interesting. Building a Vertical Behavioral Analysis System Well, that is going to be interesting. I have not seen much going on in that space and if I had to have some criticism on the cloud connect conference it would be the lack of concrete user cases on big data. The telco example, while a step into the vertical behavioral part is not really on big data. It used a sample of data from the customers' data warehouse. One thing I do think, and this is where I think parts of the NoSQL stuff come from, is that we will be doing this analysis where the data is. Over the past 10 years we at Oracle have called this in-database analytics. I guess we were (too) early? Now the entire market is going there including companies like SAS. In-place btw does not mean "no data movement at all", what it means that you will do this on data's permanent home. For SAS that is kind of the current problem. Most of the inputs live in a data warehouse. So why move it into SAS and back? That all worked with 1 TB data warehouses, but when we are looking at 100TB to 500 TB of distilled data... Comments? As it is still early days with these systems, I'm very interested in seeing reactions and thoughts to some of these thoughts...

  • PeopleSoft Upgrades, Fusion, & BI for Leading European PeopleSoft Applications Customers

    - by Mark Rosenberg
    With so many industry-leading services firms around the globe managing their businesses with PeopleSoft, it’s always an adventure setting up times and meetings for us to keep in touch with them, especially those outside of North America who often do not get to join us at Oracle OpenWorld. Fortunately, during the first two weeks of May, Nigel Woodland (Oracle’s Service Industries Director for the EMEA region) and I successfully blocked off our calendars to visit seven different customers spanning four countries in Western Europe. We met executives and leaders at four Staffing industry firms, two Professional Services firms that engage in consulting and auditing, and a Financial Services firm. As we shared the latest information regarding product capabilities and plans, we also gained valuable insight into the hot technology topics facing these businesses. What we heard was both informative and inspiring, and I suspect other Oracle PeopleSoft applications customers can benefit from one or more of the following observations from our trip. Great IT Plans Get Executed When You Respect the Users Each of our visits followed roughly the same pattern. After introductions, Nigel outlined Oracle’s product and technology strategy, including a discussion of how we at Oracle invest in each layer of the “technology stack” to provide customers with unprecedented business management capabilities and choice. Then, I provided the specifics of the PeopleSoft product line’s investment strategy, detailing the dramatic number of rich usability and functionality enhancements added to release 9.1 since its general availability in 2009 and the game-changing capabilities slated for 9.2. What was most exciting about each of these discussions was that shortly after my talking about what customers can do with release 9.1 right now to drive up user productivity and satisfaction, I saw the wheels turning in the minds of our audiences. Business analyst and end user-configurable tools and technologies, such as WorkCenters and the Related Action Framework, that provide the ability to tailor a “central command center” to the exact needs of each recruiter, biller, and every other role in the organization were exactly what each of our customers had been looking for. Every one of our audiences agreed that these tools which demonstrate a respect for the user would finally help IT pole vault over the wall of resistance that users had often raised in the past. With these new user-focused capabilities, IT is positioned to definitively partner with the business, instead of drag the business along, to unlock the value of their investment in PeopleSoft. This topic of respecting the user emerged during our very first visit, which was at Vital Services Group at their Head Office “The Mill” in Manchester, England. (If you are a student of architecture and are ever in Manchester, you should stop in to see this amazingly renovated old mill building.) I had just finished explaining our PeopleSoft 9.2 roadmap, and Mike Code, PeopleSoft Systems Manager for this innovative staffing company, said, “Mark, the new features you’ve shown us in 9.1/9.2 are very relevant to our business. As we forge ahead with the 9.1 upgrade, the ability to configure a targeted user interface with WorkCenters, Related Actions, Pivot Grids, and Alerts will enable us to satisfy the business that this upgrade is for them and will deliver tangible benefits. In fact, you’ve highlighted that we need to start talking to the business to keep up the momentum to start reviewing the 9.2 upgrade after we get to 9.1, because as much as 9.1 and PeopleTools 8.52 offers, what you’ve shown us for 9.2 is what we’ve envisioned was ultimately possible with our investment in PeopleSoft applications.” We also received valuable feedback about our investment for the Staffing industry when we visited with Hans Wanders, CIO of Randstad (the second largest Staffing company in the world) in the Netherlands. After our visit, Hans noted, “It was very interesting to see how the PeopleSoft applications have developed. I was truly impressed by many of the new developments.” Hans and Mike, sincere thanks for the validation that our team’s hard work and dedication to “respecting the users” is worth the effort! Co-existence of PeopleSoft and Fusion Applications Just Makes Sense As a “product person,” one of the most rewarding things about visiting customers is that they actually want to talk to me. Sometimes, they want to discuss a product area that we need to enhance; other times, they are interested in learning how to extract more value from their applications; and still others, they want to tell me how they are using the applications to drive real value for the business. During this trip, I was very pleased to hear that several of our customers not only thought the co-existence of Fusion applications alongside PeopleSoft applications made sense in theory, but also that they were aggressively looking at how to deploy one or more Fusion applications alongside their PeopleSoft HCM and FSCM applications. The most common deployment plan in the works by three of the organizations is to upgrade to PeopleSoft 9.1 or 9.2, and then adopt one of the new Fusion HCM applications, such as Fusion Performance Management or the full suite of  Fusion Talent Management. For example, during an applications upgrade planning discussion with the staffing company Hays plc., Mark Thomas, who is Hays’ UK IT Director, commented, “We are very excited about where we can go with the latest versions of the PeopleSoft applications in conjunction with Fusion Talent Management.” Needless to say, this news was very encouraging, because it reiterated that our applications investment strategy makes good business sense for our customers. Next Generation Business Intelligence Is the Key to the Future The third, and perhaps most exciting, lesson I learned during this journey is that our audiences already know that the latest generation of Business Intelligence technologies will be the “secret sauce” for organizations to transform business in radical ways. While a number of the organizations we visited on the trip have deployed or are deploying Oracle Business Intelligence Enterprise Edition and the associated analytics applications to provide dashboards of easy-to-understand, user-configurable metrics that help optimize business performance according to current operating procedures, what’s most exciting to them is being able to use Business Intelligence to change the way an organization does business, grows revenue, and makes a profit. In particular, several executives we met asked whether we can help them minimize the need to have perfectly structured data and at the same time generate analytics that improve order fulfillment decision-making. To them, the path to future growth lies in having the ability to analyze unstructured data rapidly and intuitively and leveraging technology’s ability to detect patterns that a human cannot reasonably be expected to see. For illustrative purposes, here is a good example of a business problem where analyzing a combination of structured and unstructured data can produce better results. If you have a resource manager trying to decide which person would be the best fit for an assignment in terms of ensuring (a) client satisfaction, (b) the individual’s satisfaction with the work, (c) least travel distance, and (d) highest margin, you traditionally compare resource qualifications to assignment needs, calculate margins on past work with the client, and measure distances. To perform these comparisons, you are likely to need the organization to have profiles setup, people ranked against profiles, margin targets setup, margins measured, distances setup, distances measured, and more. As you can imagine, this requires organizations to plan and implement data setup, capture, and quality management initiatives to ensure that dependable information is available to support resourcing analysis and decisions. In the fast-paced, tight-budget world in which most organizations operate today, the effort and discipline required to maintain high-quality, structured data like those described in the above example are certainly not desirable and in some cases are not feasible. You can imagine how intrigued our audiences were when I informed them that we are ready to help them analyze volumes of unstructured data, detect trends, and produce recommendations. Our discussions delved into examples of how the firms could leverage Oracle’s Secure Enterprise Search and Endeca technologies to keyword search against, compare, and learn from unstructured resource and assignment data. We also considered examples of how they could employ Oracle Real-Time Decisions to generate statistically significant recommendations based on similar resourcing scenarios that have produced the desired satisfaction and profit margin results. --- Although I had almost no time for sight-seeing during this trip to Europe, I have to say that it may have been one of the most energizing and engaging trips of my career. Showing these dedicated customers how they can give every user a uniquely tailored set of tools and address business problems in ways that have to date been impossible made the journey across the Atlantic more than worth it. If any of these three topics intrigue you, I’d recommend you contact your Oracle applications representative to arrange for more detailed discussions with the appropriate members of our organization.

Solutions that make life easier for our customers draw attention to themselves. We tend to engage more when there is a distinct benefit and we can take a deep breath and accept that there is hope in the world and everything isn’t designed to frustrate us and make our lives miserable. (sigh…) When products are designed to automate processes that were consuming hours of our time with no relief in sight, they deserve to be recognized. One of our recent Oracle Fusion Middleware Innovation Award Winners in the WebCenter category, Life Technologies, has recently posted a video promoting their “award winning” solution. The Oracle Innovation Awards are part of the overall Oracle Excellence awards given to customers for innovation with Oracle products. More info here. Their award nomination included this description: Life Technologies delivered the My Life Service Portal as part of a larger Digital Hub strategy. This Portal is the first of its kind in the biotechnology service providing industry. The Portal provides access to Life Technologies cloud based service monitoring system where all customer deployed instruments can be remotely monitored and proactively repaired. The portal provides alerts from these cloud based monitoring services directly to the customer and to Life Technologies Field Engineers. The Portal provides insight into the instruments and services customers purchased for the purpose of analyzing and anticipating future customer needs and creating targeted sales and service programs. This portal not only provides benefits for Life Technologies internal sales and service teams but provides customers a central place to track all pertinent instrument information including: instrument service history instrument status and previous activities instrument performance analytics planned service visits warranty/contract information discussion forums social networks for lab management and collaboration alerts and notifications on all of the above team scheduling for instrument usage promote optional reagents required to keep instruments performing From their website The Life Technologies Instruments & Services Portal Helps You Save Time and Gain Peace of Mind Introducing the new, award-winning, free online tool that enables easier management of your instrument use and care, faster response to requests for service or service quotes, and instant sharing of key instrument and service information with your colleagues. Now – this unto itself is obviously beneficial for their customers who were previously burdened with having to do all of these tasks separately, manually and inconsistently by nature. Now – all in one place and free to their customers – a portal that ties it all together. They now have built the platform to give their customers yet another reason to do business with them – Their headline on their product page says it all: “Life is now easier to manage - All your instrument use and care in one place – the no-cost, no-hassle Instruments and Services Portal.” Of course – it’s very convenient that the company name includes “Life” and now can also promote to their clients and prospects that doing business with them is easy and their sophisticated lab equipment is easy to manage. In an industry full of PhD’s – “Easy” isn’t usually the first word that comes to mind, but Life Technologies has now tied the word to their brand in a very eloquent way. Between our work lives and family or personal lives, getting any mono-focused minutes of dedicated attention has become such a rare occurrence in our current era of multi-tasking that those moments of focus are highly prized. So – when something is done really well – so well that it becomes captivating and urges sharing impulses – I take notice and dig deeper and most of the time I discover other gems not so hidden below the surface. And then I share with those I know would enjoy and understand. In the spirit of full disclosure, I must admit here that the first person I shared the videos below with was my daughter. She’s in her senior year of high school in the midst of her college search. She’s passionate about her academics and has already decided that she wants to study Neuroscience in college and like her mother will be in for the long haul to a PhD eventually. In a summer science program at Smith College 2 summers ago – she sent the family famous text to me – “I just dissected a sheep’s brain – wicked cool!” – This was followed by an equally memorable text this past summer in a research mentorship in Neuroscience at UConn – “Just sliced up some rat brain. Reminded me of a deli slicer at the supermarket… sorry I forgot to call last night…” So… needless to say – I knew I had an audience that would enjoy and understand these videos below and are now being shared among her science classmates and faculty. And evidently - so does Life Technologies! They’ve done a great job on these making them fun and something that will easily be shared among their customers social networks. They’ve created a neuro-archetypal character, “Ph.Diddy” and know that their world of clients in academics, research, and other institutions would understand and enjoy the “edutainment” value in this series of videos on their YouTube channel that pokes fun at the stereotypes while also promoting their products at the same time. They use their Facebook page for additional engagement with their clients and as another venue to promote these videos. Enjoy this one as well! More to be found here: http://www.youtube.com/lifetechnologies Stay tuned to this Oracle WebCenter blog channel. Tomorrow we'll be taking a look at another winner of the Innovation Awards, LADWP - helping to keep the citizens of Los Angeles engaged with their Water and Power provider.

  • Learning content for MCSDs: Web Applications and Windows Store Apps using HTML5

    Recently, I started again to learn for various Microsoft certifications. First candidate on my way to MSCD: Web Applications is the Exam 70-480: Programming in HTML5 with JavaScript and CSS3. Motivation to go for a Microsoft exam I guess, this is quite personal but let me briefly describe my intentions to go that exam. First, I'm doing web development since the 1990's. Working with HTML, CSS and Javascript is happening almost daily in my workspace. And honestly, I do not only do 'pure' web development but already integrated several HTML/CSS/Javascript frontend UIs into an existing desktop application (written in Visual FoxPro) inclusive two-way communication and data exchange. Hm, might be an interesting topic for another blog article here... Second, this exam has a very interesting aspect which is listed at the bottom of the exam's details: Credit Toward Certification When you pass Exam 70-480: Programming in HTML5 with JavaScript and CSS3, you complete the requirements for the following certification(s): Programming in HTML5 with JavaScript and CSS3 Specialist Exam 70-480: Programming in HTML5 with JavaScript and CSS3: counts as credit toward the following certification(s): MCSD: Web Applications MCSD: Windows Store Apps using HTML5 So, passing one single exam will earn you specialist certification straight-forward, and opens the path to higher levels of certifications. Preparations and learning path Well, due to a newsletter from Microsoft Learning (MSL) I caught interest in picking up the circumstances and learning materials for this particular exam. As of writing this article there is a promotional / voucher code available which enables you to register for this exam for free! Simply register yourself with or log into your existing account at Prometric, choose the exam for a testing facility near to you and enter the voucher code HTMLJMP (available through 31.03.2013 or while supplies last). Hurry up, there are restrictions... As stated above, I'm already very familiar with web development and the programming flavours involved into this. But of course, it is always good to freshen up your knowledge and reflect on yourself. Microsoft is putting a lot of effort to attract any kind of developers into the 'App Development'. Whether it is for the Windows 8 Store or the Windows Phone 8 Store, doesn't really matter. They simply need more apps. This demand for skilled developers also comes with a nice side-effect: Lots and lots of material to study. During the first couple of hours, I could easily gather high quality preparation material - again for free! Following is just a small list of starting points. If you have more resources, please drop me a message in the comment section, and I'll be glad to update this article accordingly. Developing HTML5 Apps Jump Start This is an accelerated jump start video course on development of HTML5 Apps for Windows 8. There are six modules that are split into two video sessions per module. Very informative and intense course material. This is packed stuff taken from an official preparation course for exam 70-480. Developing Windows Store Apps with HTML5 Jump Start Again, an accelerated preparation video course on Windows 8 Apps. There are six modules with two video sessions each which will catapult you to your exam. This is also related to preps for exam 70-481. Programming Windows 8 Apps with HTML, CSS, and JavaScript Kraig Brockschmidt delves into the ups and downs of Windows 8 App development over 800+ pages. Great eBook to read, study, and to practice the samples - best of all, it's for free. codeSHOW() This is a Windows 8 HTML/JS project with the express goal of demonstrating simple development concepts for the Windows 8 platform. Code, code and more code... absolutely great stuff to study and practice. Microsoft Virtual Academy I already wrote about the MVA in a previous article. Well, if you haven't registered yourself yet, now is the time. The list is not complete for sure, but this might keep you busy for at least one or even two weeks to go through the material. Please don't hesitate to add more resources in the comment section. Right now, I'm already through all videos once, and digging my way through chapter 4 of Kraig's book. Additional material - Pluralsight Apart from those free online resources, I also following some courses from the excellent library of Pluralsight. They already have their own section for Windows 8 development, but of course, you get companion material about HTML5, CSS and Javascript in other sections, too. Introduction to Building Windows 8 Applications Building Windows 8 Applications with JavaScript and HTML Selling Windows 8 Apps HTML5 Fundamentals Using HTML5 and CSS3 HTML5 Advanced Topics CSS3 etc... Interesting to see that Michael Palermo provides his course material on multiple platforms. Fantastic! You might also pay a visit to his personal blog. Hm, it just came to my mind that Aaron Skonnard of Pluralsight publishes so-called '24 hours Learning Paths' based on courses available in the course library. Would be interested to see a combination for Windows 8 App development using HTML5, CSS3 and Javascript in the future. Recommended workspace environment Well, you might have guessed it but this requires Windows 8, Visual Studio 2012 Express or another flavour, and a valid Developers License. Due to an MSDN subscription I working on VS 2012 Premium with some additional tools by Telerik. Honestly, the fastest way to get you up and running for Windows 8 App development is the source code archive of codeSHOW(). It does not only give you all source code in general but contains a couple of SDKs like Bing Maps, Microsoft Advertising, Live ID, and Telerik Windows 8 controls... for free! Hint: Get the Windows Phone 8 SDK as well. Don't worry, while you are studying the material for Windows 8 you will be able to leverage from this knowledge to development for the phone platform, too. It takes roughly one to two hours to get your workspace and learning environment, at least this was my time frame due to slow internet connection and an aged spare machine. ;-) Oh, before I forget to mention it, as soon as you're done, go quickly to the Windows Store and search for ClassBrowserPlus. You might not need it ad hoc for your development using HTML5, CSS and Javascript but I think that it is a great developer's utility that enables you to view the properties, methods and events (along with help text) for all Windows 8 classes. It's always good to look behind the scenes and to explore how it is made. Idea: Start/join a learning group The way you learn new things or intensify your knowledge in a certain technology is completely up to your personal preference. Back in my days at the university, we used to meet once or twice a week in a small quiet room to exchange our progress, questions and problems we ran into. In general, I recommend to any software craftsman to lift your butt and get out to exchange with other developers. Personally, I like this approach, as it gives you new points of view and an insight into others' own experience with certain techniques and how they managed to solve tricky issues. Just keep it relaxed and not too formal after all, and you might a have a good time away from your dull office desk. Give your machine a break, too.
