  - by SKY

  Hi, im currently getting these error on my site: Warning: array_keys() [function.array-keys]: The first argument should be an array on line 43 Warning: Invalid argument supplied for foreach() on line 44 Warning: array_diff() [function.array-diff]: Argument #1 is not an array on line 47 Warning: array_diff() [function.array-diff]: Argument #1 is not an array on line 48 And the source are: 42. $tmp = $this->network->get_user_follows($this->user->id); 43. $tmp = array_keys($tmp->followers); 44. foreach($tmp as &$v) { $v = intval($v); } 45. $tmp2 = array_keys($this->network->get_group_members($g->id)); 46. foreach($tmp2 as &$v) { $v = intval($v); } 47. $tmp = array_diff($tmp, $tmp2); 48. $tmp = array_diff($tmp, array(intval($this->user->id))); I want to know what is the problem and how i fix it. Thanks!

• Using an ActiveX object from an Outlook hosted webpage - possible?

  - by Nic Wise

  I'm trying to do the following: We have an outlook plugin, written in .NET (and C++). It does various things, and is manually installed on the end users machines (usually via AD deployment or similar) We are changing our search to use a webpage-based search, but from within outlook. That part is ok, however we want to communicate from the webpage to the surrounding outlook application. We can call into outlook by exposing an ActiveX object from our plugin, however we get security warnings, even if it's signed and marked as safe for scripting. Is this even possible? Has anyone done it? Anyone have a better way of doing it? We only need to pass in a small amount of data (a message id), and only from the webpage to outlook [update]: This is the error: automation server can't create object. We can get around it a bit by turning things off in IE, but thats not a good way to do it! Thanks

• iPhone: How to run a Beta build, in addition to the App Store build?

  - by rondoagogo

  Hi, All! I have an app on the Store for which we’re readying an update. The other members of our team have the App Store version already loaded up (~purchased) on their respective iPhones -- and those contain User Data which each member needs to be able to keep. In the meantime, we need to test out a Beta version of the next version of the app. Presumably, we’d need to have the two versions (ad hoc, and app store) co-existing on each device, at least until everyone’s signed off on the beta, and it’s uploaded to the store (at which point, they'd delete the beta version). [Once it’s on the Store, of course, they can each update their main (i.e., Release) version of the app via the usual App Store 'update' mechanism -- and then delete the beta version from their devices. In that case, all their user data is still retained intact.] So assuming that’s the proper workflow ... How do I issue a Beta to the team, and have it not replace/overwrite the existing App Store version? I’ve tried customizing parameters in the beta’s “[appname]-Info.plist”, but haven’t found a setting yet that allows the two versions (beta and release) to co-exist on the same device. Any ideas? And is this this is the proper approach to them being able to keep their data? (And last, how might I do it with & without a script? I assume there's just one parameter that'd need to be changed.) I hope this all makes sense -- thank you in advance for your help!

• Run SQL Scripts from C# application across domains

  - by Saravanan AR

  To run sql script files from my C# application, I referred this. http://social.msdn.microsoft.com/Forums/en/adodotnetdataproviders/thread/43e8bc3a-1132-453b-b950-09427e970f31 it works perfectly when my machine and DB server are in the same domain. my problem now is, i'm executing this console application from a machine (name: X, user id: abc, domain D1). the SQL server is in another machine (name: Y, domain: D2). I use VPN to connect to machine Y with user id 'abc' and work on SQL in remote desktop. how can i run sql scripts across domains? I use this in a custom activity in my TFS build template as the last step to run the scripts in the target database which is in domain D2. i'm getting this error: "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)" is it possible to connect to the DB using the admin user ID of machine Y in domain D2?

• Connecting flex/php to Active Directory

  - by modz0r

  Is there a way to connect my flex web application to Active Directory, and get the logged username? Right now we have a PHP script connected to the flex application, that gets user/pass input from the user and checks if there's such user in the AD, and that the password is correct. I don't want to ask for user/pass, but to make the application get the domain username that connected to it, so I could use it (check if the user has access to my application and such). Is there a way to do so?

• Data Integration Solution?

  - by Shlomo

  At my company we have a number of data feeds and processing that run on any given day. The number of feeds and processing steps is starting to out-number the ability to manage it ad-hoc as it is managed currently. Is there a good solution that helps with logging and managing/scheduling dependencies? For example: A: When file x is FTP dropped into directory D1, kick off processing step B B: Load flat file into DB1 C: When file y is FTP dropped into directory D2, kick off processing Step D D: Load flat file into DB11 E: When B and D are done, churn through the data, and load new data into DB111. F: When Step E is done, launch application process P G: etc... I want those steps to run at the appropriate times, not to mention if B fails, there's no reason to run steps E & F, but I could still run C & D. When I re-run B successfully, it should trigger just E & F to re-run, not C & D. We're a .NET/C#/Sql Server shop, and I'm already familiar with SSIS. Is that really the best there is? That manages steps well, but not external dependencies, or logging. Open source (.NET) preferred, but not required.

• Socket stops communicating

  - by user1392992

  I'm running python 2.7 code on a Raspberry Pi that receives serial data from an Arduino, processes it, and sends it to a Windows box over a wifi link. The Pi is wired to a Linksys router running in client bridge mode and that router connects over wifi to another Linksys router to which the Windows box is wired. The code in the Pi runs fine for some (apparently) random interval, and then the Pi becomes unreachable from the Windows box. I'm running PUTTY on the the Windows machine to connect to the Pi and when the fail occurs I get a message saying there's been a network error and the Pi is not reachable. Pinging the Pi from the Windows machine works fine until the error, at which time it produces "Reply from 192.168.0.129: Destination host unreachable." The client bridge router to which the Pi is connected remains reachable. I've got the networking code on the Pi wrapped in an exception handler, and when it fails it shows the following: Ethernet problem: Traceback (most recent call last): File "garage.py", line 108, in module s.connect((host, port)) File "/usr/lib/python2.7/socket.py", line 224, in meth return getattr(self._sock,name)(*args) error: [Errno 113] No route to host None The relevant python code looks like: import socket import traceback host = '192.168.0.129' port = 31415 in the setup, and after serial data has been processed: try: bline = strline.encode('utf-8') s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((host, port)) s.send(bline) s.close() except: print "Ethernet problem: " print traceback.print_exc() Where strline contains the processed data. As I said, this runs fine for a few hours more or less before failing. Any ideas? EDIT: When PUTTY fails its error message is :Network Error: Software caused connection abort."

• FLV Player Skin Custom URL

  - by Chris

  I have a flash banner ad (AS3) which uses a FLV Player component for a remove video. The Skin exports it's own SWF file for user with the video controls as I'm sure anyone familiar with Flash knows. Is there anyway to specify where this file is remotely? I have to provide 1 file to my advertiser, and do not want to have to create custom video controls for this. Is it possible to upload this swf file to a remote location and tell Flash to pull it from there? Any help would be greatly appreciated.

• Is this a bad indexing strategy for a table?

  - by llamaoo7

  The table in question is part of a database that a vendor's software uses on our network. The table contains metadata about files. The schema of the table is as follows Metadata ResultID (PK, int, not null) MappedFieldname (char(50), not null) Fieldname (PK, char(50), not null) Fieldvalue (text, null) There is a clustered index on ResultID and Fieldname. This table typically contains millions of rows (in one case, it contains 500 million). The table is populated by 24 workers running 4 threads each when data is being "processed". This results in many non-sequential inserts. Later after processing, more data is inserted into this table by some of our in-house software. The fragmentation for a given table is at least 50%. In the case of the largest table, it is at 90%. We do not have a DBA. I am aware we desperately need a DB maintenance strategy. As far as my background, I'm a college student working part time at this company. My question is this, is a clustered index the best way to go about this? Should another index be considered? Are there any good references for this type and similar ad-hoc DBA tasks?

• selective UnknownHostException

  - by Stephan

  Hi everybody! I am getting said Exception in my program, but only in certain cases. First of all, I have the internet permission set:<uses-permission android:name="android.permission.INTERNET" />, and I tried the two method of this and this thread (they don't work in my case). The scenario is the following: I send a GET request to a rest service (e.g. http://my.web.site/request.php?attr=blah) and I do get a correct xml back. Now, in this xml there are some resources described, one of which is an url to an image (e.g http://my.web.site/images/img.jpg). Here it's where it fails! Here I consistently receive a UnknownHostException. I find it weird, since it's the same domain and everything. Accessing the img url from browser works (both from the emulator browser and pc browser). I tried from a device too but it doesn't get the image anyway. Any idea on why this weird behavior? EDIT: all my tests were on emulator and device, but connected to a wifi network. I tried also using the internet connection of my provider on the phone (i.e. bypassing home network), and still the behavior is the same... I found this bug which I assume is the source of this problem, but still no solution (after more than 1.5years). Any ideas?

• Mercurial "server"

  - by user85116

  I've been using mercurial for a little while, but mainly for my own usage. Now though, I have a project I'm working on where two of us are building the same project, and we will probably be modifiying each other's files. I would like to setup a mercurial repo on a server, make that repo the "server", so my changes and the other editor's changes both push to that server (so basically the subversion / cvs model); I like mercurial though, and don't want to switch to something like subversion. Here in my own network, everything is done on linux, and my "server" has openssh installed. So pushing my changes (I work on multiple computers) from one computer to the server is just a matter of "hg push"; the protocol used is ssh for transfering the changes. The problem is that I use linux, the server will be windows (so no openssh, right?) and the other editor will be using windows too. As far as I know, the best way of working in mercurial in these types of setups is for the repo to pull changes from the source, rather then the source pushing to the "server". I'm behind several firewall's (not entirely my network) and my computer won't be visible from the server, and I'm assuming the other editor will be behind a firewall too (so we can't just start up the local mercurial http server and get the "server" computer to pull from that). What's the best way for both editors to get our changes to the server repo? (I should add that the server is a server on the internet, so just as visible as something like google.com. It's a hosted windows server, but I would probably have permission to install software if needed for this)

• Returning a href within a string

  - by user701254

  How can I return a href within a string, I can access the start position but not sure how to get last position : Here is what I have so far : String str = "sadf ad fas dfa http:\\www.google.com sdfa sadf as dfas"; int index = str.indexOf("http"); String href = str.substring(index , ???); What should the end index be ? Note, this is targeted at j2me & I need to minimise download footprint so I cannot use regular expressions or third party regular expressions libraries.

• How to create your own advert engine for an Android App?

  - by Richard Green

  I have an Android App and I would like to start putting non-intrusive advert into the app. However, I have the benefit of knowing exactly what products I would like to put in these adverts (which will basically be amazon "similar products" type things and a few other suppliers). Is there any ad-engine out there that will allow me to do this? The ones I see already just put what they think are suitable. I have scoured and I can't find an example of this... Any ideas? Should I just bite the bullet and write my own classes to do this ?

• Creation of AsyncTask taking too much time Android

  - by user2842342

  I am making a network call in an AsyncTask, but the problem i am facing is the amount of time it is taking to start the doInBackground method. Here is a part of my code: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Log.d("Temp:",System.currentTimeMillis()+""); new Move().execute(); /*some other logic } } And my AsyncTask is: private class Move extends AsyncTask<Void, Void, Void> { @Override protected Void doInBackground(Void... temp) { Log.d("start:",System.currentTimeMillis()+""); gson.fromJson(Web.Request.get(some_URL),Void.class); Log.d("end:",System.currentTimeMillis()+""); return null; } } These are the logs i got: 32658-998/com.example.game D/temp:? 1408923006159 32658-998/com.example.game D/start:? 1408923035163 32658-998/com.example.game D/end:? 1408923035199 So actually it took almost 29 secs to reach the first line in doInBackground method, where as it took just 36 ms to finish the network call. I tried it many times, the time taken is almost in the same order. Is it possible to start the AsyncTask immediately? Or is there any other way to solve this problem.(other than a running a simple thread?) Thank you :)

• Android Service Testing with messages

  - by Sandeep Dhull

  I have a service which does its work(perform network operation) depending upon the type of message(message.what) property of the message. Then it returns the resoponse, also as a message to the requesting component(depending upon the message.replyTo). So, i am trying to write the testcases.. But how????? My Architecture of service is like this: 1) A component(ex. Activity) bounds to the service. 2) The component sends message to the Service(using Messenger). 3) The service has a nested class that handles the messages and execute the network call and returns a response as message to the sender(who initially sent the message and using its replyTo property). Now to test this.. i am using Junit test cases.. So , in that .. 1) in setUp() i am binding to the service.. 2) on testBusinessLogic() . i am sending the message to the service .. Now problem is where to get the response message.

• Submit form without page reloading

  - by Camran

  I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form... So anybody who wants can send a tip of the ad to some friends email-adress. I am guessing the form must be submitted to a php page right? <form name='tip' method='post' action='tip.php'> Tip somebody: <input name="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/> <input type="submit" value="Skicka Tips"/> <input type="hidden" name="ad_id" /> </form> When submitting the form, the page gets reloaded... I don't want that... Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery... Thanks

• return not breaking loop (c#)

  - by David Wick

  I'm trying to determine if a user is a member of a group or not in AD. However, the following doesn't seem to be working for some reason... public bool MemberOf(string sObjectName, string sGroup, bool bIsGroup) { DirectoryEntry dEntry = CreateDirectoryEntry(); DirectorySearcher dSearcher = new DirectorySearcher(dEntry); if (bIsGroup) dSearcher.Filter = "(distinguishedName=" + sObjectName + ")"; else dSearcher.Filter = "(&(sAMAccountName=" + sObjectName + ")(objectClass=user))"; SearchResult sResult = dSearcher.FindOne(); if (sResult != null) { foreach (object oGroup in sResult.Properties["MemberOf"]) { if (oGroup.ToString() == sGroup) return true; else this.MemberOf(oGroup.ToString(), sGroup, true); } } return false; } Another variation: http://users.business.uconn.edu/dwick/work/wtf/6-14-2010%201-15-15%20PM.png Doesn't work either. This seems like a really dumb question... but shouldn't it break the loop upon "return true;"

• Failling install Ralink RT5592 driver on Ubuntu 14.04 LTS

  - by atisou

  My problem concerns the installation of a wi-fi driver (RT5592) for my new wi-fi adapter (PCE-N53) on my newly built computer. Basically, I don't manage to get the driver installed and therefore I cannot get the wifi to work. I know I am not the only one having this issue this year, between RT5592 driver and Ubuntu 14.04 LTS, in one way or the other. Is there anybody who has ever been able to fix this problem? It does not look like on all the posts I have been through... Following an answer to a same problem as mine (I was getting the same error message as Christopher Kyle Horton of "incompatible types" etc), I have applied the instructions and done the editings in a script as suggested by Paul B. Unfortunately I still do get error/warnings message (a different one this time) at the end of the make and the wi-fi still does not work. Below is a snapshot of the end of the message: In file included from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/os/rt_linux.h:31:0, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_os.h:44, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/include/rtmp_comm.h:69, from /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:31: include/linux/module.h:88:32: error: ‘__mod_pci_device_table’ aliased to undefined symbol ‘rt2860_pci_tbl’ extern const struct gtype##_id __mod_##gtype##_table \ ^ include/linux/module.h:146:3: note: in expansion of macro ‘MODULE_GENERIC_TABLE’ MODULE_GENERIC_TABLE(type##_device,name) ^ /home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.c:73:1: note: in expansion of macro ‘MODULE_DEVICE_TABLE’ MODULE_DEVICE_TABLE(pci, rt2860_pci_tbl); ^ cc1: some warnings being treated as errors make[2]: *** [/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux/../../os/linux/pci_main_dev.o] Error 1 make[1]: *** [_module_/home/username/Downloads/PCE-N53/Linux/DPO_GPL_RT5592STA_LinuxSTA_v2.6.0.0_20120326/os/linux] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-3.13.0-32-generic' make: *** [LINUX] Error 2 The full pastebin data: paste.ubuntu.com/8088834/ It looks from the message that one would need to edit manually some of/other scripts in the driver package, as did Paul B suggest in one case. But I have no idea how to do that. Here is the driver package of the wifi adapter: www.asus.com/uk/Networking/PCEN53/HelpDesk_Download/ My system is as following: OS: ubuntu 14.04 LTS wi-fi card: Asus PCE-N53 motherboard: Asus KCMA-D8 processor: AMD Opteron 4228 HE kernel: 3.13.0-32-generic Following this info from chili555 in here, below are some extra info about my system: lspci -nn | grep 0280 gives 04:00.0 Network controller [0280]: Ralink corp. RT5592 PCI2 Wireless Network Adapater [1814:5592] and sudo apt-get install linux-headers-generic returns linux-headers-generic is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. If this is a kernel version (I have 3.13.0-32-generic) incompatibility issue with the driver as chilli555 suggests (the README file in the driver package says indeed it is compatible with kernel 2.6), how could one trick this around to make it work? that should be possible right? On ubuntu forums, the patches proposed dont work (leads the computer to freeze). Basically: is there anybody out there who has ever been able to make a PCE-N53 work on Ubuntu 14.04 LTS (kernel 3.13)? how shall I edit the driver package to make it work for my kernel?

• Is Agile the new micromanagement?

  - by Smith James

  Hi, This question has been cooking in my head for a while so I wanted to ask those who are following agile/scrum practices in their development environments. My company has finally ventured into incorporating agile practices and has started out with a team of 4 developers in an agile group on a trial basis. It has been 4 months with 3 iterations and they continue to do it without going fully agile for the rest of us. This is due to the fact that management's trust to meet business requirements with a quite a bit of ad hoc type request from high above. Recently, I talked to the developers who are part of this initiative; they tell me that it's not fun. They are not allowed to talk to other developers by their Scrum master and are not allowed to take any phone calls in the work area (which maybe fine to an extent). For example, if I want to talk to my friend for kicks who is in the agile team, I am not allowed without the approval of the Scrum master; who is sitting right next to the agile team. The idea of all this or the agile is to provide a complete vacuum for agile developers from any interruptions and to have them put in good 6+ productive hours. Well, guys, I am no agile guru but what I have read Yahoo agile rollout document and similar for other organizations, it gives me a feeling that agile is not cheap. It require resources and budget to instill agile into the teams and correct issue as they arrive to put them back on track. For starters, it requires training for developers and coaching for managers and etc, etc... The current Scrum master was a manager who took a couple days agile training class paid by the management is now leading this agile team. I have also heard in the meeting that agile manifesto doesn't dictate that agile is not set in stones and is customized differently for each company. Well, it all sounds good and reason. In conclusion, I always thought the agile was supposed to bring harmony in the development teams which results in happy developers. However, I am getting a very opposite feeling when talking to the developers in the agile team. They are unhappy that they cannot talk anything but work, sitting quietly all day just working, and they feel it's just another way for management to make them work more. Tell me please, if this is one of the examples of good practices used for the purpose of selfish advantage for more dollars? Or maybe, it's just us the developers like me and this agile team feels that they don't like to work in an environment where they only breathe work because they are at work. Thanks. Edit: It's a company in healthcare domain that has offices across US, but we're in Texas. It definitely feels like a cowboy style agile which makes me really not wanting to go for agile at all, esp at my current company. All of it has to do with the management being completely cheap. Cutting out expensive coffee for cheaper version, emphasis on savings and being productive while staying as lean as possible. My feeling is that someone in the management behind the door threw out this idea, that agile makes you produce more so we can show our bosses we're producing more with the same headcount. Or, maybe, it will allow us to reduce headcount if that's the case. EDITED: They are having their 5 min daily meeting. But not allowed to chat or talk with someone outside of their team. All focus is on work.

• How to use crontab, .netrc, and git push?

  - by Jon

  Hi all, I am in the process of automating the backups from various servers to a central point then pushing those config changes into a git repo so i can track any changes over time. The rest of the scripts are working well, I can copy / rsync the files across the network to a central point. The last script is to get the config files to be put into / updated in repository. The script is as follows: #!/bin/bash clear SERVERNAME="betty" SCRIPTDIR="/home/jon" GITROOT="/tmp/git" TEMPROOT="/tmp/backups" BACKUPROOTDIR="/mnt/backups" echo " - running as user: $UID" echo "backingup git config on $SERVERNAME" echo "" # check to see if root backup folder exists, otherwise create it. if [ -d $GITROOT ]; then rm -rf $GITROOT fi mkdir $GITROOT cd $GITROOT echo " - testing if home is where I think it should be!" echo $HOME echo " - testing if it can see netrc" tail $HOME/.netrc git clone http://192.168.10.97:8000/repositories/HOH-config-backups.git cd HOH-config-backups echo " - copy Configuration Folders across" cp -r $BACKUPROOTDIR/Configuration/* $GITROOT/HOH-config-backups/ cp -r $BACKUPROOTDIR/scripts $GITROOT/HOH-config-backups/ git add . git commit -a -m "committing any new configuration changes!" git push origin master echo "" echo "Git repo updated" echo "" echo " - backing up this script" FIREWIGSCRIPTLOC="$BACKUPROOTDIR/scripts/$SERVERNAME" if [ ! -d $FIREWIGSCRIPTLOC ]; then mkdir $FIREWIGSCRIPTLOC fi cp /home/jon/gitConfig.sh $FIREWIGSCRIPTLOC The git repo is on a different machine in the network using Apache and HTTP-backend.exe (smart HTTP protocol). If I run this script as me "jon" it works. If I run it in crontab it fails. git uses the /home/jon/.netrc file for authentication: machine 192.168.10.97 login gitconfig password 1234579 The log from crontab is: TERM environment variable not set. - running as user: 1000 backingup git config on betty - testing if home is where I think it should be! /home/jon - testing if it can see netrc machine 192.168.10.97 login gitconfig password 1234579 got 08de5bc2b27b4940d9412256e76d5e3c3d9dbcdd walk 08de5bc2b27b4940d9412256e76d5e3c3d9dbcdd got be880f2d306778a538d592e7a02eb19f416612f7 got bd387e8def9f77aafa798bf53e80d949aba443e8 got 1bc1a59e12775841d4c59d77c63b8a73823138c2 walk bd387e8def9f77aafa798bf53e80d949aba443e8 Getting alternates list for http://192.168.10.97:8000/repositories/HOH-config-backups.git got 030512237bca72faf211e0e8ec2906164eac34f6 got 9bc2f575240bc1f61ff7d69777ce1a165d06b184 got b8400f7f01429104a9d4786a6bb1a16d293e37c1 got 2403b5bf611010e0b401f776f0e23b09ce744838 got 1a27944c48269ef3608a8f2466e43402d06faac0 got b686f45b7d57af4fa8ca0d528bb85216d6247e19 Getting pack list for http://192.168.10.97:8000/repositories/HOH-config-backups.git Getting index for pack ae881957c0f0e8c22eb6cc889a22ef78eb4ce6ff Getting pack ae881957c0f0e8c22eb6cc889a22ef78eb4ce6ff which contains ff84d6d48e9326066438d167a10251218d612b3d walk b686f45b7d57af4fa8ca0d528bb85216d6247e19 got 364e30daec17814073e668f490bb84af891fe1f7 got 23f6497e7f9b80e0d90adad73bd0407a0e5ac6ce got 9e77c47574b5e23ea669afe0c23ab235e4917ee1 got 6654e0d328a216b3783e98c47206cb2d01b3353d got 28821ffd437d2689ffb82c6e4b9c3f5372c95c4b got 8c384a24f645389e4d4b08013c79e9e73a658342 got d203be0123736ee025ce20c081f1489098648dfc got 1852603bf7709e71417d8ccec02390279d533642 got fb753a26b20b04694419fce8ecdaa8dbec105cf1 got 736028997cd84dd1c135f57e9d246674b9cd0b9d got 7af836249e20096d0476a548d5be702a071cdd4b got 240dc39d9db50df63073fc7927b2d002dfa0f54c got 93abd36e3935a01011eb753b635a1a0e984bf31e got c6269e28fecf4d8d0d98b9358aecb3acff02df44 got b0aa29432f73e64032682a351d436c24b14078ab walk 240dc39d9db50df63073fc7927b2d002dfa0f54c got 58fb66d9f35f8a5e32ff4683309c5f0c2a3a03c5 got 0da2def4de0565483cdbe6b87418ee2beb122e58 got 0f6a86c6f87ed52ad2ed01e5c6edd661d364930c got 437a93d27b5bb89c739a0564a34a616e832c3ebe got fe0385abe5c0acd8462268dac330bae00e934f1b got 24259f8f5c5c9ee974a75fe3d1e07c02e3e20fe9 got d29f624bf1a5eceedaa86c10fee35f62747c7d04 got 0154e4c987132585ea7a92b77d02dba285512d6b got eda8bf526567c25ee70addb2ad3c3c6aa57eac77 got 9f3d9d7262d66f9fa4f6a13b7c86199953f4bc4e got 8e20881e19667aa22245d0598646991067455a4d got abb1123145689b35eb19519952c71253ee45fa98 got dfeff593c79b4156ce2ce1adf043d0e80356488c got e20c5b48b1d360e0bcf34189e3f3d2bbf23e92cc got b13eb81cc274780322ecf786372320343926bec9 walk 8de83868b3fac748b0a55eba16c8f668ec852abb got b5961421bbc42afe7a07cc1c8b615aba26ba74d7 got 2650ba819019df4193b482733e29ca79b29f3f2c got b3111e1be8103e91803a97a817ed81f28025aca1 got b060be934d709684f5eb5dad3c03932a3589e864 got cf70d2043f081d7a4438e9d5a290a9f986c84060 got 80bf0f1cc836feab86d6935bb7968d8555a8d531 got da318d167920e34bc6573e4fc236249ccbbee316 got d82ac853d387b760149599e6e1ab96403f6ec672 got 0005f691d1f46550fdb4e56025f52e30a5b18cc2 Initialized empty Git repository in /tmp/git/HOH-config-backups/.git/ - copy Configuration Folders across Created commit 424df2f: committing any new configuration changes! 3 files changed, 55 insertions(+), 1 deletions(-) create mode 100755 scripts/betty/gitConfig.sh error: Cannot access URL http://192.168.10.97:8000/repositories/HOH-config-backups.git/, return code 22 error: failed to push some refs to 'http://192.168.10.97:8000/repositories/HOH-config-backups.git' Git repo updated - backing up this script cp: cannot create regular file `/mnt/backups/scripts/betty/gitConfig.sh': Permission denied my crontab is: # m h dom mon dow command 04 * * * * /home/jon/gitConfig.sh > /tmp/gitconfig.log 2>&1 I open it by doing: $crontab -e i.e. not as root.

• OWB 11gR2 &ndash; OLAP and Simba

  - by David Allan

  Oracle Warehouse Builder was the first ETL product to provide a single integrated and complete environment for managing enterprise data warehouse solutions that also incorporate multi-dimensional schemas. The OWB 11gR2 release provides Oracle OLAP 11g deployment for multi-dimensional models (in addition to support for prior releases of OLAP). This means users can easily utilize Simba's MDX Provider for Oracle OLAP (see here for details and cost) which allows you to use the powerful and popular ad hoc query and analysis capabilities of Microsoft Excel PivotTables® and PivotCharts® with your Oracle OLAP business intelligence data. The extensions to the dimensional modeling capabilities have been built on established relational concepts, with the option to seamlessly move from a relational deployment model to a multi-dimensional model at the click of a button. This now means that ETL designers can logically model a complete data warehouse solution using one single tool and control the physical implementation of a logical model at deployment time. As a result data warehouse projects that need to provide a multi-dimensional model as part of the overall solution can be designed and implemented faster and more efficiently. Wizards for dimensions and cubes let you quickly build dimensional models and realize either relationally or as an Oracle database OLAP implementation, both 10g and 11g formats are supported based on a configuration option. The wizard provides a good first cut definition and the objects can be further refined in the editor. Both wizards let you choose the implementation, to deploy to OLAP in the database select MOLAP: multidimensional storage. You will then be asked what levels and attributes are to be defined, by default the wizard creates a level bases hierarchy, parent child hierarchies can be defined in the editor. Once the dimension or cube has been designed there are special mapping operators that make it easy to load data into the objects, below we load a constant value for the total level and the other levels from a source table.   Again when the cube is defined using the wizard we can edit the cube and define a number of analytic calculations by using the 'generate calculated measures' option on the measures panel. This lets you very easily add a lot of rich analytic measures to your cube. For example one of the measures is the percentage difference from a year ago which we can see in detail below. You can also add your own custom calculations to leverage the capabilities of the Oracle OLAP option, either by selecting existing template types such as moving averages to defining true custom expressions. The 11g OLAP option now supports percentage based summarization (the amount of data to precompute and store), this is available from the option 'cost based aggregation' in the cube's configuration. Ensure all measure-dimensions level based aggregation is switched off (on the cube-dimension panel) - previously level based aggregation was the only option. The 11g generated code now uses the new unified API as you see below, to generate the code, OWB needs a valid connection to a real schema, this was not needed before 11gR2 and is a new requirement since the OLAP API which OWB uses is not an offline one. Once all of the objects are deployed and the maps executed then we get to the fun stuff! How can we analyze the data? One option which is powerful and at many users' fingertips is using Microsoft Excel PivotTables® and PivotCharts®, which can be used with your Oracle OLAP business intelligence data by utilizing Simba's MDX Provider for Oracle OLAP (see Simba site for details of cost). I'll leave the exotic reporting illustrations to the experts (see Bud's demonstration here), but with Simba's MDX Provider for Oracle OLAP its very simple to easily access the analytics stored in the database (all built and loaded via the OWB 11gR2 release) and get the regular features of Excel at your fingertips such as using the conditional formatting features for example. That's a very quick run through of the OWB 11gR2 with respect to Oracle 11g OLAP integration and the reporting using Simba's MDX Provider for Oracle OLAP. Not a deep-dive in any way but a quick overview to illustrate the design capabilities and integrations possible.

• How do NTP Servers Manage to Stay so Accurate?

  - by Akemi Iwaya

  Many of us have had the occasional problem with our computers and other devices retaining accurate time settings, but a quick sync with an NTP server makes all well again. But if our own devices can lose accuracy, how do NTP servers manage to stay so accurate? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Photo courtesy of LEOL30 (Flickr). The Question SuperUser reader Frank Thornton wants to know how NTP servers are able to remain so accurate: I have noticed that on my servers and other machines, the clocks always drift so that they have to sync up to remain accurate. How do the NTP server clocks keep from drifting and always remain so accurate? How do the NTP servers manage to remain so accurate? The Answer SuperUser contributor Michael Kjorling has the answer for us: NTP servers rely on highly accurate clocks for precision timekeeping. A common time source for central NTP servers are atomic clocks, or GPS receivers (remember that GPS satellites have atomic clocks onboard). These clocks are defined as accurate since they provide a highly exact time reference. There is nothing magical about GPS or atomic clocks that make them tell you exactly what time it is. Because of how atomic clocks work, they are simply very good at, having once been told what time it is, keeping accurate time (since the second is defined in terms of atomic effects). In fact, it is worth noting that GPS time is distinct from the UTC that we are more used to seeing. These atomic clocks are in turn synchronized against International Atomic Time or TAI in order to not only accurately tell the passage of time, but also the time. Once you have an exact time on one system connected to a network like the Internet, it is a matter of protocol engineering enabling transfer of precise times between hosts over an unreliable network. In this regard a Stratum 2 (or farther from the actual time source) NTP server is no different from your desktop system syncing against a set of NTP servers. By the time you have a few accurate times (as obtained from NTP servers or elsewhere) and know the rate of advancement of your local clock (which is easy to determine), you can calculate your local clock’s drift rate relative to the “believed accurate” passage of time. Once locked in, this value can then be used to continuously adjust the local clock to make it report values very close to the accurate passage of time, even if the local real-time clock itself is highly inaccurate. As long as your local clock is not highly erratic, this should allow keeping accurate time for some time even if your upstream time source becomes unavailable for any reason. Some NTP client implementations (probably most ntpd daemon or system service implementations) do this, and others (like ntpd’s companion ntpdate which simply sets the clock once) do not. This is commonly referred to as a drift file because it persistently stores a measure of clock drift, but strictly speaking it does not have to be stored as a specific file on disk. In NTP, Stratum 0 is by definition an accurate time source. Stratum 1 is a system that uses a Stratum 0 time source as its time source (and is thus slightly less accurate than the Stratum 0 time source). Stratum 2 again is slightly less accurate than Stratum 1 because it is syncing its time against the Stratum 1 source and so on. In practice, this loss of accuracy is so small that it is completely negligible in all but the most extreme of cases. Have something to add to the explanation? Sound off in the comments.

• Is Agile the new micromanagement?

  - by Smith James

  This question has been cooking in my head for a while so I wanted to ask those who are following agile/scrum practices in their development environments. My company has finally ventured into incorporating agile practices and has started out with a team of 4 developers in an agile group on a trial basis.
