  • Cannot Start MySQL Server on Fresh MAMP Install

    - by alexpelan
    I'm using Mac OS X 10.6.2 on my Macbook Pro. I can get the apache server to start, but not the mysql server, on both the default apache and default MAMP ports. When I try to go to my start page, I get the message "Error: Could not connect to MySQL server!" . Here's what's in my mysql error log: 00513 02:00:07 mysqld_safe mysqld from pid file /Applications/MAMP/tmp/mysql/mysql.pid ended 100513 02:00:16 mysqld_safe Starting mysqld daemon with databases from /Applications/MAMP/db/mysql 100513 2:00:16 [Warning] The syntax '--log_slow_queries' is deprecated and will be removed in a future release.

  • SQLExpress service unable to start Error code 17053

    - by Chris Sobolewski
    A user was instructed by their software support to upgrade a program and install SQLExpress as part of the installation process. Since that time, the service has been able to start, citing error 17053, which appears to be an authentication issue. Here is the error log: 2011-01-11 13:17:45.50 Server Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Express Edition on Windows NT 5.1 (Build 2600: Service Pack 2) 2011-01-11 13:17:45.50 Server (c) 2005 Microsoft Corporation. 2011-01-11 13:17:45.50 Server All rights reserved. 2011-01-11 13:17:45.50 Server Server process ID is 3332. 2011-01-11 13:17:45.50 Server Authentication mode is WINDOWS-ONLY. 2011-01-11 13:17:45.50 Server Logging SQL Server messages in file 'c:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\ERRORLOG'. 2011-01-11 13:17:45.52 Server This instance of SQL Server last reported using a process ID of 2332 at 11/10/2010 2:15:24 PM (local) 11/10/2010 7:15:24 PM (UTC).

Unfortunately, that is resulting in the error message The Security ID Structure is Invalid [0x80070539] Any help either uninstalling or getting SQLExpress running would be fantastic.

  • Windows 7 sometimes boots in VGA mode

    - by TuxRug
    I have an Asus G50VT-x5 laptop with nVidia GeForce9800M-GS graphics. Normally, Windows boots normally, but about 20% of the time (rough estimate), it will boot with the fallback VGA driver, maxing out at 800x600 with no Aero. I've checked the system logs and there is nothing indicating an error loading the nVidia driver. It even specifies in the logs that the Nvidia Display Driver service started successfully, even though it has booted in safe graphics mode. This has been happening for a while, but it's happening a little more often now than it was before. Since the first time my system exhibited this behavior, I have updated my graphics driver a handful of times. I used System Information for Windows to check for problems there, but the only thing that stood out was the following: Core Temperature 4486449 °C (8075639 °F) Shaders Temperature 1171513530 °C (2108724330 °F) I know this reading is incorrect, because my laptop is nowhere near the surface of the sun and my desk has not burst into flames. When it's opererating normally, I get a sane reading like [Core Temperature 58 °C (136 °F)] with no Shaders Temperature listed. All I have to do to resolve the issue is reboot. I have seen no stability issues with the graphics or anything else. A long time ago, I had an issue with this computer where my framerate would suddenly drop during a 3D game from 40fps to <1fps, but after looking at the temperature readout immediately after quitting a game, I removed the bottom panel and blew the dust out of the vent and heatsink. Since then I have no drops in framerate under any situation. I have uploaded a zip containing the SIW reports for when the problem is occurring and when the computer is operating normally. I don't have a paid account so it can only be downloaded 10 times, so please only download the reports if you think you can use them. If you try to download the reports and they are no longer available, please comment and I will re-upload them. If you want to look at the files, they are on Rapidshare. EDIT It happened again, and I looked a little deeper into the System logs. When this happens, there are a lot of errors about other device drivers unable to start. All of these errors are for PnP drivers. Also, my USB keyboard and mouse take a few moments before they actually start working, although this happens sometimes the first normal boot as well. I am quite sure this is related, so I am adding the pnp tag. Also, CHKDSK will not run on boot. Even if a check is scheduled or a volume is manually set as dirty, CHKDSK will be skipped entirely, not even leaving an entry in the System logs. I tried running CHKNTFS /D, which did not work. I then manually changed my HKLM\System\CurrentControlSet\Control\Session Manager BootExecute value to the default listed on Microsoft's website. That did not work either. I ended up booting to repair mode and running CHKDSK there, which found a number of minor inconsistencies on my system drive, but none on my data drive. I have no idea if this is related. Some more information for those who don't download my SIW report file: Antivirus and Firewall are ESET Smart Security I have three different virutalization programs installed: VMware Player, Windows Virtual PC, and VirtualBox. The network adapters for these show up in the log of failed device starts. EDIT 2 I tried running sfc /scannow, which reported that it found corrupted files that could not be fixed. The CBS log is extremely cryptic. I tried booting to my install disk, launching repair mode, and doing an offline sfc from there, which produced the same result.

  • Ubuntu 14.04, OpenLDAP TLS problems

    - by larsemil
    So i have set up an openldap server using this guide here. It worked fine. But as i want to use sssd i also need TLS to be working for ldap.

  • Asus P8P67 Rev. 3.1 Motherboard issues powering on and saving settings

    - by Scott
    Edit: New Information Have some updated information from the old question below: So basically my issue right now is somewhat similar, but I've been able to rule out a couple of things. I don't think this has anything to do with light on the motherboard. No matter what lights are on/off on the motherboard when the computer is off, they don't affect this issue. The main power LED on the Mobo is always lit when the power supply is turned on, and that's what matters anyway. Even when the main power LED is on, the PC will NOT boot up the first time I hit the power switch. I have to go reset the power supply (make all lights turn off on the Mobo and back on), and THEN hit the power switch. Then everything boots up. Also, the BIOS settings are reset every time this happens. Asus Tech Support told me to try jumping the power with something metal to try and rule out that it's a problem with the connectors getting power, or if it's a problem with the case power switch pins - haven't done that yet though. Any ideas? This is a lot simpler than it was before when I thought it had to do with certain LED indicators for RAM, EPU, etc. Original Question So I built my new desktop just about 3 weeks ago. I've been having a few issues which I think are all related to my motherboard, an Asus P8P67 Revision 3.1, but I'm not 100% sure as this is really the first from-scratch build I've ever done. I've posted these questions on the Asus forums, Asus Tech Support, and the Corsair forums as well as I thought it might have something to do with my power supply at one point. None of these avenues have solved my issue until now completely, so I thought I'd come here to see what you guys think. Here's what's happening: My computer is off, and I go to power it on. I press the power switch on the case (Antec Nine Hundred), and nothing seems to happen. Upon further inspection, I see that what this actually does is simply turn on the EPU LED on my motherboard, but doesn't actually boot anything up. I then have to go and flip the main power switch on the power supply off and back on. What this does is turn off all lights on the Motherboard after a few seconds, and turn them all back on (including the EPU LED that was off before I hit the power switch the first time). Now, hitting the power switch works. The machine boots up fine, and starts going through the boot up process. As a side note: My Motherboard is set to "Force BIOS", and every single time I change this to do the opposite, the next time my computer boots up that change reverts itself. I think this may be due to the fact that I am doing the hard reset on the power supply each time, but I'm not sure. I had thought that the Motherboard would keep its BIOS settings unless you did something to the Mobo itself - so this may be a related issue, or something else completely. That's basically it. Once it's on, it's on. It works fine, recognizes all of my hardware, and runs great. All fans/lights in the case work great, and I'm getting standard readings. The next time I go to shut the computer down however, I can expect the same exact process getting it up and running, including being forced to go into BIOS and exit again before I can load Windows. Another side note: If I power on my computer using the power switch DIRECTLY after shutting it down, it powers right back on (I think this is because the EPU LED light doesn't have time to turn off). It looks as if as long as the EPU LED is lit up on the motherboard before I hit the power switch on the case, the thing will boot up fine (although this doesn't explain the "Force BIOS" issue, at least it's something). Any ideas? Thanks guys.

  • RAID controller dropping the wrong drive

    - by bramp
    I've been having an issue with 3ware 9500S-8 RAID 10, and I have contracted their tech support, but I wanted to hear the serverfault community's recommendations. Firstly, all my data is backuped and secure, so I don't mind blowing my RAID away if I have to. But let me describe the problem I've been seeing. A month ago, disk 6 dropped out of the RAID. It is mirrored with disk 7, so I wasn't that bothered. I went to the data centre and replaced it. When I got back to the office, I noticed that disk 6 will still not in the RAID, and in fact the controller was show the name of the old drive still. A week later I went back and replace the drive again, thinking I might have swapped in a bad drive. Still the same problem. I decided to reboot the machine, to see if that would "force" the controller into seeing the new drive. It did, and a rebuild started to happen (from disk 7). Eventually both drives were showing as good. A week later, the MySQL database has flagged the database is corrupt, and is unable to repair it. I don't know what has gone wrong, but I suspected this 6-7 pair. At this point I noticed that the RAID had constantly been verifying itself, over and over. Regardless of this I began to rebuild the database, which took about 19 hours. It's a big database. Near the end of the repair, the RAID controller told me it had dropped disk 7, and that some data was most likely corrupted. I contacted LSI tech support, and they very promptly started to help me. I mentioned that drive 7 had been dropped. They suspect that drive 7 was always at fault, and drive 6 had always been good. I want to know how often a RAID controller would drop the wrong drive (in this case dropping drive 6 a month ago, instead of 7). I foolishly didn't run smartctl on the drives before I started swapping them out. I just assumed the RAID controller knew what it was talking about. I think my plan of action is to replace drive 7, rebuild the array from scratch, double check smartctl on ALL the disks, and then start restoring my data again. I would appreciate anyone's input on what the correct procedure for swapping drives is, and how often failures like this happen. If anyone would like more information then I'd be happy to provide it. thanks in advance. Oh some more information. I'm running CentOS 5.3, with two RAID arrays, a simple RAID 1 for the OS, and RAID 10 for the database. Both arrays are on different controllers. The RAID 10 is made of 10 identical ST3640323AS drives, until I swapped in a SAMSUNG HD103SJ last month.

  • How can I make subversion reset the stored passwords/users and remember my authentication credential

    - by NicDumZ
    Hello folks! Background: I used to have everything working just fine on my fresh install: $ svn co https://domain:443/ test1 Error validating server certificate for 'https://domain:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: **REMOVED** - Valid: **REMOVED** - Issuer: **REMOVED** - Fingerprint: **checked with issuer and REMOVED** (R)eject, accept (t)emporarily or accept (p)ermanently? p Authentication realm: <https://domain:443> Subversion repository Password for 'nicdumz-machine-hostname': Authentication realm: <https://domain:443> Subversion repository Username: nicdumz Password for 'nicdumz': # proceeds to checkout correctly $ svn co https://domain:443/ test2 # checkouts nicely, without asking for my password. At some point I needed to commit stuff using a different account. So I did that $ svn ci --username other.user Authentication realm: <https://domain:443> Subversion repository Password for 'other.user': # works fine But since then, everytime I want to commit as 'nicdumz' (default user, all repos have been checked-out with that user), it prompts me for my password: $ svn ci Authentication realm: <https://domain:443> Subversion repository Password for 'nicdumz': Hey come on, why :) The same happens if I want a fresh checkout, since read-access is also protected. So I tried fixing the issue by myself. I read around that ~/.subversion/auth was storing credentials, so I removed it from the way: $ cd ~/.subversion $ mv auth oldauth $ mkdir auth It seemed to work at first, because svn had forgotten about certificate validation: $ svn co https://domain:443/ test3 Error validating server certificate for 'https://domain:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: **REMOVED** - Valid: **REMOVED** - Issuer: **REMOVED** - Fingerprint: **checked with issuer and REMOVED** (R)eject, accept (t)emporarily or accept (p)ermanently? p Authentication realm: <https://domain:443> Subversion repository Password for 'nicdumz-machine-hostname': Authentication realm: <https://domain:443> Subversion repository Username: nicdumz Password for 'nicdumz': # proceeds to checkout correctly $ svn up Authentication realm: <https://domain:443> Subversion repository Password for 'nicdumz': What? how is this happening? If you have suggestions to investigate more about the behaviour, I am very interested. If I'm correct, there is no way to do a verbose svn up or anything of the like, so I'm not sure should I go for investigation. Oh, and for what it's worth: $ svn --version svn, version 1.6.6 (r40053) compiled Oct 26 2009, 06:19:08 Copyright (C) 2000-2009 CollabNet.

  • Setting environment variables in OS X

    - by Percival Ulysses
    Despite the warning that questions that can be answered are preferred, this question is more a request for comments. I apologize for this, but I feel that it is valuable nonetheless. The problem to set up environment variables such that they are available for GUI applications has been around since the dawn of Mac OS X. The solution with ~/.MacOSX/environment.plist never satisfied me because it was not reliable, and bash style globbing wasn't available. Another solution is the use of Login Hooks with a suitable shell script, but these are deprecated. The Apple approved way for such functionality as provided by login hooks is the use of Launch Agents. I provided a launch agent that is located in /Library/LaunchAgents/: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>user.conf.launchd</string> <key>Program</key> <string>/Users/Shared/conflaunchd.sh</string> <key>ProgramArguments</key> <array> <string>~/.conf.launchd</string> </array> <key>EnableGlobbing</key> <true/> <key>RunAtLoad</key> <true/> <key>LimitLoadToSessionType</key> <array> <string>Aqua</string> <string>StandardIO</string> </array> </dict> </plist> The real work is done in the shell script /Users/Shared/conflaunchd.sh, which reads ~/.conf.launchd and feeds it to launchctl: #! /bin/bash #filename="$1" filename="$HOME/.conf.launchd" if [ ! -r "$filename" ]; then exit fi eval $(/usr/libexec/path_helper -s) while read line; do # skip lines that only contain whitespace or a comment if [ ! -n "$line" -o `expr "$line" : '#'` -gt 0 ]; then continue; fi eval launchctl $line done <"$filename" exit 0 Notice the call of path_helper to get PATH set up right. Finally, ~/.conf.launchd looks like that setenv PATH ~/Applications:"${PATH}" setenv TEXINPUTS .:~/Documents/texmf//: setenv BIBINPUTS .:~/Documents/texmf/bibtex//: setenv BSTINPUTS .:~/Documents/texmf/bibtex//: # Locale setenv LANG en_US.UTF-8 These are launchctl commands, see its manpage for further information. Works fine for me (I should mention that I'm still a Snow Leopard guy), GUI applications such as texstudio can see my local texmf tree. Things that can be improved: The shell script has a #filename="$1" in it. This is not accidental, as the file name should be feeded to the script by the launch agent as an argument, but that doesn't work. It is possible to put the script in the launch agent itsself. I am not sure how secure this solution is, as it uses eval with user provided strings. It should be mentioned that Apple intended a somewhat similar approach by putting stuff in ~/launchd.conf, but it is currently unsupported as to this date and OS (see the manpage of launchd.conf). I guess that things like globbing would not work as they do in this proposal. Finally, I would mention the sources I used as information on Launch Agents, but StackExchange doesn't let me [1], [2], [3]. Again, I am sorry that this is not a real question, I still hope it is useful.

    Server setup The problem Diagnostic information What I've tried Specific Help needed 1. I have the following server setup: Debian Squeeze Linux 2.6.32-5-amd64 Apache2-mpm-prefork 2.2.16-6+squeeze10 PHP 5.3.3-7+squeeze14 This server is protected with the Suhosin Patch 0.9.9.1 Max Requests Per Child: 0 - Keep Alive: on - Max Per Connection: 100 Timeouts Connection: 300 - Keep-Alive: 15 Loaded Modules core mod_log_config mod_logio prefork http_core mod_so mod_alias mod_auth_basic mod_auth_digest mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_cgi mod_deflate mod_dir mod_env mod_mime mod_negotiation mod_php5 mod_reqtimeout mod_rewrite mod_setenvif mod_ssl mod_status Wordpress 3.4.2 (Upgrading to 3.5 soon :) 2. The problem When I restart the server (sudo shutdown -r now), going to any website page results in the following error from the web browser (in this case, Google Chrome, but other browsers also show the same error). This error can also occur an hour or so after all is working ok, seemingly randomly, which is my biggest concern as it means my server is not reliable: No data received Unable to load the web page because the server sent no data. Here are some suggestions: Reload this web page later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data. 3. Diagnostic information The apache error log contains the folowing entries: [Fri Dec 14 22:23:27 2012] [notice] child pid 1955 exit signal Floating point exception (8) [Fri Dec 14 22:23:27 2012] [notice] child pid 1956 exit signal Floating point exception (8) [Fri Dec 14 22:23:29 2012] [notice] child pid 1957 exit signal Floating point exception (8) [Fri Dec 14 22:23:30 2012] [notice] child pid 1958 exit signal Floating point exception (8) [Fri Dec 14 22:23:32 2012] [notice] child pid 1959 exit signal Floating point exception (8) [Fri Dec 14 22:23:32 2012] [notice] child pid 1960 exit signal Floating point exception (8) [Fri Dec 14 22:23:34 2012] [notice] child pid 1961 exit signal Floating point exception (8) [Fri Dec 14 22:23:34 2012] [notice] child pid 1962 exit signal Floating point exception (8) 4. What I've tried a) I can 'fix' the website temporarily by resetting the server twice (resetting it once does not work) using the following commands. NB: the 'reload' option does not work, I have to use restart twice. However, the error can reoccur sometime later. sudo /etc/init.d/apache2 restart sudo /etc/init.d/apache2 restart b) I have tried disabling suhosin by uninstalling php5-suhosin, but a php info page still shows "This server is protected with the Suhosin Patch 0.9.9.1". I have tried putting Suhosin into simulation mode by creating a file /etc/php5/apache2/conf.d/suhosin.ini containing: [suhosin] suhosin.simulation = On The php info page shows the suhosin.ini file in the list of "Additional .ini files parsed" but the php info page still shows "This server is protected with the Suhosin Patch 0.9.9.1" c) Increasing the PHP memory limit In /etc/php5/apache2/ : ; Maximum amount of memory a script may consume (128MB) ; http://php.net/memory-limit memory_limit = 512M d) Disabling all Wordpress plugins, and going back to the default theme. 5. Specific help needed I would very much like help in debugging what is going on here. I am not sure how to determine what processes are in the Apache error log which are exiting "[notice] child pid 1955 exit signal Floating point exception (8)", or what is causing them to exit. And whether suhosin is part of the problem (and how to disable it if it is). Thank you in advance for any advice or tips you can offer in helping me debug this.

  • KVM with one host IP and a different subnet for machines

    - by Jguy
    I've already setup a KVM host with proper IP configurations, but my host had me create DHCP and use that to assign the IP's to the machines. I want to see if there's an easier way to do it (or better). Upon my first setting out on this, I didn't find anything that pointed me in the right direction. I'm coming off a fresh install of Debian 6.0 x64, so I have nothing installed. I've logged in, queried for the below information and changed the password from my host set one. I have a Debian 6.0 x64 system with the following initial network configuration (substituted 255 in place of my real first octave): # tail /etc/network/interfaces auto eth0 iface eth0 inet static address 255.9.24.80 broadcast 255.9.24.95 netmask 255.255.255.224 gateway 255.9.24.65 # default route to access subnet up route add -net 255.9.24.64 netmask 255.255.255.224 gw 255.9.24.65 eth0 I have a /29 subnet that I want the virtual machines to use from my host: IP: 255.46.187.152 /29 Mask: 255.255.255.248 Broadcast: 255.46.187.159 Usable IP addresses: 255.46.187.153 to 255.46.187.158 I like the interface of Cloudmin, so I want to try and use that if I can to administrate my guests. So, my questions: How do I set this up on the host system the best so that I can use the additional Subnet IP's on the guests and have them accessible from the internet? I also need to host a DNS server, which means one of these VM's has to have two IP's assigned to it and accessable from the outside world. How can I do that using Cloudmin? I had a question about this here: Multiple IP addresses assigned to one KVM VM But I just reformatted the entire server and am trying to figure out a better way of doing this. Machine information: # ip route show 255.9.24.64/27 via 255.9.24.65 dev eth0 255.9.24.64/27 dev eth0 proto kernel scope link src 255.9.24.80 default via 255.9.24.65 dev eth0 brctl is empty # ip addr list 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether c8:60:00:54:b5:d8 brd ff:ff:ff:ff:ff:ff inet 255.9.24.80/27 brd 255.9.24.95 scope global eth0 inet6 fe80::ca60:ff:fe54:b5d8/64 scope link valid_lft forever preferred_lft forever Thank you for any help you can provide me.

  • How to save a ntfs partition which suddenly became empty

    One ntfs partition of my laptop was suddenly wiped out without any notice to me, when I rebooted from Windows 7 to Ubuntu 12.04 today. I am in need of help to save my files on that partition, which are important and unfortunately haven't been backed up yet. My laptop has two operating systems: Windows 7 and Ubuntu 12.04. with a ntfs partition shared between the two operating systems for storing some data files (109GB, about 97%of which has been used). I have almost always been using Ubuntu, but today I happened to have to work under Windows. Following is a record of what happened in the time order, numbering according to which operating system I was in at each stage. When I started into Windows 7, right before being able to log in, it took a while and two reboots to configure the Windows. I thought it was normal, since last time when I was using Windows two weeks ago, it took very long and several reboots to update Windows, since the last time I used Windows before then was in November last year. Then after finally being able to log in Windows 7, I installed Libre Office, MathType (I got it from http://dl.portablesoft.org/down/?id=2515, which I originally thought was a trial version, but later I learned was a cracked version and felt wrong. I made a copy of it at dropbox http://dl.dropbox.com/u/13029929/MathType_6.8_PortableSoft.rar, not for distributing it but to list it there just in case it will help to identify the problem), and MikTex. I then edited some .doc files in the ntfs partition under both Microsoft Office with MathType, and Libre Office. When I finished working under Windows and rebooted into Ubuntu, Ubuntu did some filesystem checking and reported that the ntfs partition was not able to be mounted. Then I rebooted again into Windows, and found that the ntfs partition had been emptied, i.e. all the data files were gone, and only one system file bootsqm.dat and one system directory System Volume Information were there, with their last updated time being the time when I first rebooted from Windows to Ubuntu (in fact, it is 4 hours in advanced than the actual time of that rebooting , see immediately below) Also I noticed that the time shown by Windows is not correct for my time zone (UTC-05:00) Eastern Time (US & Canada)), which is 4 hours in advance than the correct time (my current time is 3am, but the computer shows 7am). Same things happened when I rebooted into Ubuntu again: the ntfs has been emptied and left with only one Windows system file bootsqm.dat and one Windows system directory System Volume Information. the time shown by Ubuntu is 4 hours in advance than the correct time. I wonder what I can do to retrieve my data files back on the ntfs partition? If I am not able to do it myself, will some professionals be able to help me out? Thanks a lot! PS: I didn't think I did any thing that required emptying that partition. But there were quite some works I did during that stage right before the reboot from Windows to Ubuntu when the problem occured. Did I make any mis-operation?

  • What networking hardware do I need in this situation (Fairpoint [ISP] "E-DIA" connection)?

    - by Tegeril
    Right away you'd probably want to say, "Well just ask Fairpoint." I've done that, a number of times in as many different ways I can phrase it and just keep hitting a brick wall where they will not commit to giving any useful information and instead recommend contracting an outside firm and spending a pile of money. Anyway... I'm trying to help a family member out with an office connection that is being setup. I've managed to scrape tiny details here and there from our discussions with the ISP (Fairpoint in Maine) about what is going to be done and what is going to be needed. This is the connection that is being setup: http://www.fairpoint.com/enterprise/vantagepoint/e-dia/index.jsp Information I have been given: Via this connection I can get IPs across different C blocks if that were necessary (it is not) Fairpoint is bringing hardware with them that they claim simply does the conversion from whatever line is coming in the building to ethernet, they have referred to this as the "Fairpoint Netvanta" which I know suggests a line of products that I have looked up, but some (most? all?) of those seems to handle all the routing that I saw. Fairpoint says that I need to bring my own router to sit behind their device. They have literally declined to even suggest products that have worked for other clients in the past and fall back on "any business router works, not a home router." That alone makes my head spin. Detail and clarity hit a brick wall from there. At one moment I got them to cough up that the router I provide needs to be able to do VPN tunneling but they typically fall back to "not a home router" and I was even given "just a business router, Cisco or something, it'll be $500-$1000". Now I know that VPN tunneling routers exist well below that price point and since this connection is going to one machine, possibly two only via ethernet, my desire to purchase networking hardware that over-delivers what I need is not very high. They are literally setting all this up, have provided no configuration details for after they finish, and expect me to just plunk a $500+ router behind it and cross my fingers or contract out to a third party company. If there were other options available for the location, I would have dropped them in a second, but there aren't. The device that is connected requires a static IP and I'm honestly a bit hazy on the necessity of an additional router behind their device and generally a bit over my head. I presume that the router needs to be able to serve external static IPs to its clients, but I really don't know what is going to show up when they come to do the install. This was originally going to be run via an ADSL bridge modem with a range of static IPs (which is easy and is currently setup properly) but the location is too far from the telco to get speeds that we really want for upload and this is also a connection that needs high availability. Any suggestions would be greatly appreciated (I see a number of options in the Cisco Small Business line and other competitors that aren't going to break the bank…), especially if you've worked with Fairpoint before! Thanks for reading my wall of text.

  • unmet dependencies in Ubuntu 12.04

    I tried today to install a dvb-card on my Ubuntu 12.04 (Linux blauhai-linux 3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ).

  • ASP.NET MVC 3 Hosting :: New Features in ASP.NET MVC 3

    - by mbridge
    Razor View Engine The Razor view engine is a new view engine option for ASP.NET MVC that supports the Razor templating syntax. The Razor syntax is a streamlined approach to HTML templating designed with the goal of being a code driven minimalist templating approach that builds on existing C#, VB.NET and HTML knowledge. The result of this approach is that Razor views are very lean and do not contain unnecessary constructs that get in the way of you and your code. ASP.NET MVC 3 Preview 1 only supports C# Razor views which use the .cshtml file extension. VB.NET support will be enabled in later releases of ASP.NET MVC 3. For more information and examples, see Introducing “Razor” – a new view engine for ASP.NET on Scott Guthrie’s blog. Dynamic View and ViewModel Properties A new dynamic View property is available in views, which provides access to the ViewData object using a simpler syntax. For example, imagine two items are added to the ViewData dictionary in the Index controller action using code like the following: public ActionResult Index() {          ViewData["Title"] = "The Title";          ViewData["Message"] = "Hello World!"; } Those properties can be accessed in the Index view using code like this: <h2>View.Title</h2> <p>View.Message</p> There is also a new dynamic ViewModel property in the Controller class that lets you add items to the ViewData dictionary using a simpler syntax. Using the previous controller example, the two values added to the ViewData dictionary can be rewritten using the following code: public ActionResult Index() {     ViewModel.Title = "The Title";     ViewModel.Message = "Hello World!"; } “Add View” Dialog Box Supports Multiple View Engines The Add View dialog box in Visual Studio includes extensibility hooks that allow it to support multiple view engines, as shown in the following figure: Service Location and Dependency Injection Support ASP.NET MVC 3 introduces improved support for applying Dependency Injection (DI) via Inversion of Control (IoC) containers. ASP.NET MVC 3 Preview 1 provides the following hooks for locating services and injecting dependencies: - Creating controller factories. - Creating controllers and setting dependencies. - Setting dependencies on view pages for both the Web Form view engine and the Razor view engine (for types that derive from ViewPage, ViewUserControl, ViewMasterPage, WebViewPage). - Setting dependencies on action filters. Using a Dependency Injection container is not required in order for ASP.NET MVC 3 to function properly. Global Filters ASP.NET MVC 3 allows you to register filters that apply globally to all controller action methods. Adding a filter to the global filters collection ensures that the filter runs for all controller requests. To register an action filter globally, you can make the following call in the Application_Start method in the Global.asax file: GlobalFilters.Filters.Add(new MyActionFilter()); The source of global action filters is abstracted by the new IFilterProvider interface, which can be registered manually or by using Dependency Injection. This allows you to provide your own source of action filters and choose at run time whether to apply a filter to an action in a particular request. New JsonValueProviderFactory Class The new JsonValueProviderFactory class allows action methods to receive JSON-encoded data and model-bind it to an action-method parameter. This is useful in scenarios such as client templating. Client templates enable you to format and display a single data item or set of data items by using a fragment of HTML. ASP.NET MVC 3 lets you connect client templates easily with an action method that both returns and receives JSON data. Support for .NET Framework 4 Validation Attributes and IvalidatableObject The ValidationAttribute class was improved in the .NET Framework 4 to enable richer support for validation. When you write a custom validation attribute, you can use a new IsValid overload that provides a ValidationContext instance. This instance provides information about the current validation context, such as what object is being validated. This change enables scenarios such as validating the current value based on another property of the model. The following example shows a sample custom attribute that ensures that the value of PropertyOne is always larger than the value of PropertyTwo: public class CompareValidationAttribute : ValidationAttribute {     protected override ValidationResult IsValid(object value,              ValidationContext validationContext) {         var model = validationContext.ObjectInstance as SomeModel;         if (model.PropertyOne > model.PropertyTwo) {            return ValidationResult.Success;         }         return new ValidationResult("PropertyOne must be larger than PropertyTwo");     } } Validation in ASP.NET MVC also supports the .NET Framework 4 IValidatableObject interface. This interface allows your model to perform model-level validation, as in the following example: public class SomeModel : IValidatableObject {     public int PropertyOne { get; set; }     public int PropertyTwo { get; set; }     public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) {         if (PropertyOne <= PropertyTwo) {            yield return new ValidationResult(                "PropertyOne must be larger than PropertyTwo");         }     } } New IClientValidatable Interface The new IClientValidatable interface allows the validation framework to discover at run time whether a validator has support for client validation. This interface is designed to be independent of the underlying implementation; therefore, where you implement the interface depends on the validation framework in use. For example, for the default data annotations-based validator, the interface would be applied on the validation attribute. Support for .NET Framework 4 Metadata Attributes ASP.NET MVC 3 now supports .NET Framework 4 metadata attributes such as DisplayAttribute. New IMetadataAware Interface The new IMetadataAware interface allows you to write attributes that simplify how you can contribute to the ModelMetadata creation process. Before this interface was available, you needed to write a custom metadata provider in order to have an attribute provide extra metadata. This interface is consumed by the AssociatedMetadataProvider class, so support for the IMetadataAware interface is automatically inherited by all classes that derive from that class (notably, the DataAnnotationsModelMetadataProvider class). New Action Result Types In ASP.NET MVC 3, the Controller class includes two new action result types and corresponding helper methods. HttpNotFoundResult Action The new HttpNotFoundResult action result is used to indicate that a resource requested by the current URL was not found. The status code is 404. This class derives from HttpStatusCodeResult. The Controller class includes an HttpNotFound method that returns an instance of this action result type, as shown in the following example: public ActionResult List(int id) {     if (id < 0) {                 return HttpNotFound();     }     return View(); } HttpStatusCodeResult Action The new HttpStatusCodeResult action result is used to set the response status code and description. Permanent Redirect The HttpRedirectResult class has a new Boolean Permanent property that is used to indicate whether a permanent redirect should occur. A permanent redirect uses the HTTP 301 status code. Corresponding to this change, the Controller class now has several methods for performing permanent redirects: - RedirectPermanent - RedirectToRoutePermanent - RedirectToActionPermanent These methods return an instance of HttpRedirectResult with the Permanent property set to true. Breaking Changes The order of execution for exception filters has changed for exception filters that have the same Order value. In ASP.NET MVC 2 and earlier, exception filters on the controller with the same Order as those on an action method were executed before the exception filters on the action method. This would typically be the case when exception filters were applied without a specified order Order value. In MVC 3, this order has been reversed in order to allow the most specific exception handler to execute first. As in earlier versions, if the Order property is explicitly specified, the filters are run in the specified order. Known Issues When you are editing a Razor view (CSHTML file), the Go To Controller menu item in Visual Studio will not be available, and there are no code snippets.

  • VB.NET IF() Coalesce and “Expression Expected” Error

    - by Jeff Widmer
    I am trying to use the equivalent of the C# “??” operator in some VB.NET code that I am working in. This StackOverflow article for “Is there a VB.NET equivalent for C#'s ?? operator?” explains the VB.NET IF() statement syntax which is exactly what I am looking for... and I thought I was going to be done pretty quickly and could move on. But after implementing the IF() statement in my code I started to receive this error: Compiler Error Message: BC30201: Expression expected. And no matter how I tried using the “IF()” statement, whenever I tried to visit the aspx page that I was working on I received the same error. This other StackOverflow article Using VB.NET If vs. IIf in binding/rendering expression indicated that the VB.NET IF() operator was not available until VS2008 or .NET Framework 3.5.  So I checked the Web Application project properties but it was targeting the .NET Framework 3.5: So I was still not understanding what was going on, but then I noticed the version information in the detailed compiler output of the error page: This happened to be a C# project, but with an ASPX page with inline VB.NET code (yes, it is strange to have that but that is the project I am working on).  So even though the project file was targeting the .NET Framework 3.5, the ASPX page was being compiled using the .NET Framework 2.0.  But why?  Where does this get set?  How does ASP.NET know which version of the compiler to use for the inline code? For this I turned to the web.config.  Here is the system.codedom/compilers section that was in the web.config for this project: <system.codedom>     <compilers>         <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">             <providerOption name="CompilerVersion" value="v3.5" />             <providerOption name="WarnAsError" value="false" />         </compiler>     </compilers> </system.codedom> Keep in mind that this is a C# web application project file but my aspx file has inline VB.NET code.  The web.config does not have any information for how to compile for VB.NET so it defaults to .NET 2.0 (instead of 3.5 which is what I need). So the web.config needed to include the VB.NET compiler option.  Here it is with both the C# and VB.NET options (I copied the VB.NET config from a new VB.NET Web Application project file).     <system.codedom>         <compilers>             <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">                 <providerOption name="CompilerVersion" value="v3.5" />                 <providerOption name="WarnAsError" value="false" />             </compiler>       <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" warningLevel="4" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">         <providerOption name="CompilerVersion" value="v3.5"/>         <providerOption name="OptionInfer" value="true"/>         <providerOption name="WarnAsError" value="false"/>       </compiler>     </compilers>     </system.codedom>   So the inline VB.NET code on my aspx page was being compiled using the .NET Framework 2.0 when it really needed to be compiled with the .NET Framework 3.5 compiler in order to take advantage of the VB.NET IF() coalesce statement.  Without the VB.NET web.config compiler option, the default is to compile using the .NET Framework 2.0 and the VB.NET IF() coalesce statement does not exist (at least in the form that I want it in).  FYI, there is an older IF statement in VB.NET 2.0 compiler which is why it is giving me the unusual “Expression Expected” error message – see this article for when VB.NET got the new updated version. EDIT (2011-06-20): I had made a wrong assumption in the first version of this blog post.  After a little more research and investigation I was able to figure out that the issue was in the web.config and not with the IIS App Pool.  Thanks to the comment from James which forced me to look into this again.

  • How To Activate Your Free Office 2007 to 2010 Tech Guarantee Upgrade

    - by Matthew Guay
    Have you purchased Office 2007 since March 5th, 2010?  If so, here’s how you can activate and download your free upgrade to Office 2010! Microsoft Office 2010 has just been released, and today you can purchase upgrades from most retail stores or directly from Microsoft via download.  But if you’ve purchased a new copy of Office 2007 or a new computer that came with Office 2007 since March 5th, 2010, then you’re entitled to an absolutely free upgrade to Office 2010.  You’ll need enter information about your Office 2007 and then download the upgrade, so we’ll step you through the process. Getting Started First, if you’ve recently purchased Office 2007 but haven’t installed it, you’ll need to go ahead and install it before you can get your free Office 2010 upgrade.  Install it as normal.   Once Office 2007 is installed, run any of the Office programs.  You’ll be prompted to activate Office.  Make sure you’re connected to the internet, and then click Next to activate. Get your Free Upgrade to Office 2010 Now you’re ready to download your upgrade to Office 2010.  Head to the Office Tech Guarantee site (link below), and click Upgrade now. You’ll need to enter some information about your Office 2007.  Check that you purchased your copy of Office 2007 after March 5th, select your computer manufacturer, and check that you agree to the terms. Now you’re going to need the Product ID number from Office 2007.  To find this, open Word or any other Office 2007 application.  Click the Office Orb, and select Options on the bottom. Select the Resources button on the left, and then click About. Near the bottom of this dialog, you’ll see your Product ID.  This should be a number like: 12345-123-1234567-12345   Go back to the Office Tech Guarantee signup page in your browser, and enter this Product ID.  Select the language of your edition of Office 2007, enter the verification code, and then click Submit. It may take a few moments to validate your Product ID. When it is finished, you’ll be taken to an order page that shows the edition of Office 2010 you’re eligible to receive.  The upgrade download is free, but if you’d like to purchase a backup DVD of Office 2010, you can add it to your order for $13.99.  Otherwise, simply click Continue to accept. Do note that the edition of Office 2010 you receive may be different that the edition of Office 2007 you purchased, as the number of editions has been streamlined in the Office 2010 release.  Here’s a chart you can check to see what edition you’ll receive.  Note that you’ll still be allowed to install Office on the same number of computers; for example, Office 2007 Home and Student allows you to install it on up to 3 computers in the same house, and your Office 2010 upgrade will allow the same. Office 2007 Edition Office 2010 Upgrade You’ll Receive Office 2007 Home and Student Office Home and Student 2010 Office Basic 2007Office Standard 2007 Office Home and Business 2010 Office Small Business 2007Office Professional 2007Office Ultimate 2007 Office Professional 2010 Office Professional 2007 AcademicOffice Ultimate 2007 Academic Office Professional Academic 2010 Sign in with your Windows Live ID, or create a new one if you don’t already have one. Enter your name, select your country, and click Create My Account.  Note that Office will send Office 2010 tips to your email address; if you don’t wish to receive them, you can unsubscribe from the emails later.   Finally, you’re ready to download Office 2010!  Click the Download Now link to start downloading Office 2010.  Your Product Key will appear directly above the Download link, so you can copy it and then paste it in the installer when your download is finished.  You will additionally receive an email with the download links and product key, so if your download fails you can always restart it from that link. If your edition of Office 2007 included the Office Business Contact Manager, you will be able to download it from the second Download link.  And, of course, even if you didn’t order a backup DVD, you can always burn the installers to a DVD for a backup.   Install Office 2010 Once you’re finished downloading Office 2010, run the installer to get it installed on your computer.  Enter your Product Key from the Tech Guarantee website as above, and click Continue. Accept the license agreement, and then click Upgrade to upgrade to the latest version of Office.   The installer will remove all of your Office 2007 applications, and then install their 2010 counterparts.  If you wish to keep some of your Office 2007 applications instead, click Customize and then select to either keep all previous versions or simply keep specific applications. By default, Office 2010 will try to activate online automatically.  If it doesn’t activate during the install, you’ll need to activate it when you first run any of the Office 2010 apps.   Conclusion The Tech Guarantee makes it easy to get the latest version of Office if you recently purchased Office 2007.  The Tech Guarantee program is open through the end of September, so make sure to grab your upgrade during this time.  Actually, if you find a great deal on Office 2007 from a major retailer between now and then, you could also take advantage of this program to get Office 2010 cheaper.

  • Dependency Injection in ASP.NET MVC NerdDinner App using Ninject

    - by shiju
    In this post, I am applying Dependency Injection to the NerdDinner application using Ninject. The controllers of NerdDinner application have Dependency Injection enabled constructors. So we can apply Dependency Injection through constructor without change any existing code. A Dependency Injection framework injects the dependencies into a class when the dependencies are needed. Dependency Injection enables looser coupling between classes and their dependencies and provides better testability of an application and it removes the need for clients to know about their dependencies and how to create them. If you are not familiar with Dependency Injection and Inversion of Control (IoC), read Martin Fowler’s article Inversion of Control Containers and the Dependency Injection pattern. The Open Source Project NerDinner is a great resource for learning ASP.NET MVC.  A free eBook provides an end-to-end walkthrough of building NerdDinner.com application. The free eBook and the Open Source Nerddinner application are extremely useful if anyone is trying to lean ASP.NET MVC. The first release of  Nerddinner was as a sample for the first chapter of Professional ASP.NET MVC 1.0. Currently the application is updating to ASP.NET MVC 2 and you can get the latest source from the source code tab of Nerddinner at http://nerddinner.codeplex.com/SourceControl/list/changesets. I have taken the latest ASP.NET MVC 2 source code of the application and applied  Dependency Injection using Ninject and Ninject extension Ninject.Web.Mvc.Ninject &  Ninject.Web.MvcNinject is available at http://github.com/enkari/ninject and Ninject.Web.Mvc is available at http://github.com/enkari/ninject.web.mvcNinject is a lightweight and a great dependency injection framework for .NET.  Ninject is a great choice of dependency injection framework when building ASP.NET MVC applications. Ninject.Web.Mvc is an extension for ninject which providing integration with ASP.NET MVC.Controller constructors and dependencies of NerdDinner application Listing 1 – Constructor of DinnersController  public DinnersController(IDinnerRepository repository) {     dinnerRepository = repository; }  Listing 2 – Constrcutor of AccountControllerpublic AccountController(IFormsAuthentication formsAuth, IMembershipService service) {     FormsAuth = formsAuth ?? new FormsAuthenticationService();     MembershipService = service ?? new AccountMembershipService(); }  Listing 3 – Constructor of AccountMembership – Concrete class of IMembershipService public AccountMembershipService(MembershipProvider provider) {     _provider = provider ?? Membership.Provider; }    Dependencies of NerdDinnerDinnersController, RSVPController SearchController and ServicesController have a dependency with IDinnerRepositiry. The concrete implementation of IDinnerRepositiry is DinnerRepositiry. AccountController has dependencies with IFormsAuthentication and IMembershipService. The concrete implementation of IFormsAuthentication is FormsAuthenticationService and the concrete implementation of IMembershipService is AccountMembershipService. The AccountMembershipService has a dependency with ASP.NET Membership Provider. Dependency Injection in NerdDinner using NinjectThe below steps will configure Ninject to apply controller injection in NerdDinner application.Step 1 – Add reference for NinjectOpen the  NerdDinner application and add  reference to Ninject.dll and Ninject.Web.Mvc.dll. Both are available from http://github.com/enkari/ninject and http://github.com/enkari/ninject.web.mvcStep 2 – Extend HttpApplication with NinjectHttpApplication Ninject.Web.Mvc extension allows integration between the Ninject and ASP.NET MVC. For this, you have to extend your HttpApplication with NinjectHttpApplication. Open the Global.asax.cs and inherit your MVC application from  NinjectHttpApplication instead of HttpApplication.   public class MvcApplication : NinjectHttpApplication Then the Application_Start method should be replace with OnApplicationStarted method. Inside the OnApplicationStarted method, call the RegisterAllControllersIn() method.   protected override void OnApplicationStarted() {     AreaRegistration.RegisterAllAreas();     RegisterRoutes(RouteTable.Routes);     ViewEngines.Engines.Clear();     ViewEngines.Engines.Add(new MobileCapableWebFormViewEngine());     RegisterAllControllersIn(Assembly.GetExecutingAssembly()); }  The RegisterAllControllersIn method will enables to activating all controllers through Ninject in the assembly you have supplied .We are passing the current assembly as parameter for RegisterAllControllersIn() method. Now we can expose dependencies of controller constructors and properties to request injectionsStep 3 – Create Ninject ModulesWe can configure your dependency injection mapping information using Ninject Modules.Modules just need to implement the INinjectModule interface, but most should extend the NinjectModule class for simplicity. internal class ServiceModule : NinjectModule {     public override void Load()     {                    Bind<IFormsAuthentication>().To<FormsAuthenticationService>();         Bind<IMembershipService>().To<AccountMembershipService>();                  Bind<MembershipProvider>().ToConstant(Membership.Provider);         Bind<IDinnerRepository>().To<DinnerRepository>();     } } The above Binding inforamtion specified in the Load method tells the Ninject container that, to inject instance of DinnerRepositiry when there is a request for IDinnerRepositiry and  inject instance of FormsAuthenticationService when there is a request for IFormsAuthentication and inject instance of AccountMembershipService when there is a request for IMembershipService. The AccountMembershipService class has a dependency with ASP.NET Membership provider. So we configure that inject the instance of Membership Provider. When configuring the binding information, you can specify the object scope in you application.There are four built-in scopes available in Ninject:Transient  -  A new instance of the type will be created each time one is requested. (This is the default scope). Binding method is .InTransientScope()   Singleton - Only a single instance of the type will be created, and the same instance will be returned for each subsequent request. Binding method is .InSingletonScope()Thread -  One instance of the type will be created per thread. Binding method is .InThreadScope() Request -  One instance of the type will be created per web request, and will be destroyed when the request ends. Binding method is .InRequestScope() Step 4 – Configure the Ninject KernelOnce you create NinjectModule, you load them into a container called the kernel. To request an instance of a type from Ninject, you call the Get() extension method. We can configure the kernel, through the CreateKernel method in the Global.asax.cs. protected override IKernel CreateKernel() {     var modules = new INinjectModule[]     {         new ServiceModule()     };       return new StandardKernel(modules); } Here we are loading the Ninject Module (ServiceModule class created in the step 3)  onto the container called the kernel for performing dependency injection.Source CodeYou can download the source code from http://nerddinneraddons.codeplex.com. I just put the modified source code onto CodePlex repository. The repository will update with more add-ons for the NerdDinner application.

  • Our Look at Opera 10.50 Web Browser

    - by Asian Angel
    Everyone has been talking about the newest version of Opera recently but perhaps you have not looked at it too closely yet. Today we will take a look at 10.50 and let you see what this “new browser” is all about. The New Engines Carakan JavaScript Engine: Runs web applications up to 7 times faster than its predecessor Futhark Vega Graphics Library: Enables super fast and smooth graphics on everything from tab switching to webpage animation Presto 2.5: Provides support for HTML5, CSS2.1 and the latest CSS3 standards A Look at the Features Available If you have installed or used older versions of Opera before then the default look after a clean install will probably seem rather different. The main differences in appearance are mainly located within the “glass border” areas of the browser. The “Speed Dial” setup looks and works just as well as in previous versions. You can set a favorite wallpaper or image as your background and choose the number of “dials” using the “Configure Speed Dial Command”. One of the “standout” differences is the “O Button”. All of the menus have been condensed into this single access point but it only takes a few moments to find what you are looking for. If you have used the style before in earlier versions of Opera some of the items have been moved around. For those who prefer the “Menu Bar” that can be easily restored using the “Show Menu Bar Command”. If desired you can actually “extend” the “Tab Bar” downwards to display thumbnails of your open tabs. Just use your mouse to grab the bottom of the “Tab Bar” and adjust it to suit your personal needs. The only problem with this feature is that it will quickly use up a good sized portion of your available UI and browser window space. The “Password Manager” is ready to access when needed…the background for the button will turn a shiny metallic blue when you open a webpage that you have “Login Information” saved for. One of the new features is a small “Recycle Bin Button” in the upper right corner. Clicking on this will display a list of recently closed tabs letting you have easy access to any tabs that you may have accidentally closed. This is definitely a great feature to have as an easy access button. For those who were used to how the “Zoom Feature” looked before it has a new “look” to it. Instead of the pop-up menu-type listing of “view sizes” present before you now have a slider button that you can use to adjust the zooming level. For our default setup here the “Sidebar Panels” available were: “Bookmarks, Widgets, Unite, Notes, Downloads, History, & Panels”. Additional panels such as “Links, Windows, Search, Info, etc.” are available if you want and/or need them (accessible using the “Panels Plus Sign Button”). The “Opera Link Button” makes it easy for you to synchronize your “Speed Dial, Bookmarks, Personal Bar, Custom Searches, History & Notes”. Note: “Opera Link” requires an account and can be signed up for using the link provided below. Want to share files with your family and friends? “Unite” allows you to do that and more. With “Unite” you can: “Stream Music, Show Photo Galleries, Share Files and/or Folders, & host webpages directly from your browser”. We have a more in-depth look at “Unite” in our article here. Note: Use of “Unite” requires an Opera account. Got a slow internet connection? “Opera Turbo” can help with that by running the web traffic through their “compression servers” to speed up your web browsing. Keep in mind that “Opera Turbo” will not engage if you are accessing a secure website (i.e. your bank’s website) thus preserving your security. Note: “Opera Turbo” can be set up to automatically detect slow internet connections (i.e. crowded Wi-Fi in a cafe). Opera has a built-in “Private Browsing Mode” now for those who prefer anonymous browsing and want to keep the “history records clean” on their computer. To access it go to “Tabs and windows” and select “New private tab” or “New private window” as desired. When you open your new “Private Tab or Window” you will see the following message with details on how Opera will handle browsing information and a large “door hanger symbol”. Notice that the one tab is locked into “Private Browsing Mode” while the others are still working in “Regular Browsing Mode”. Very nice! A miniature version of the “door hanger symbol” will be present on any tab that is locked into “Private Browsing Mode”. If you are using Windows 7 then you will love how things look from your “Taskbar”. Here you can see four very nice looking thumbnails for the tabs that we had open. All that you have to do is click on the desired thumbnail… The “Context Menu” looks just as lovely as the thumbnails and definitely has some terrific functionality built into it. Add Enhanced Aero Capability If you love “Aero” and want more for your new Opera install then we have the perfect theme for you. The theme’s name is Z1-AV69 and once you have downloaded it you will need to place it in the “Skins Subfolder” in Opera’s “Program Files Folder”. Note: For our example we used version 1.10 but version 2.00 is now available (link provided below). Once you have restarted Opera, go to the “O Menu” and select “Appearance”. When the “Appearance Window” opens click on “Z1-Glass Skin” and then click “OK”. All of a sudden you will have more “Aero Goodness” to enjoy. Compare this screenshot with the one at the top of this article…the only part that is not transparent now is the browser window area itself. Want even more “Aero Goodness”? Right click on the “Tab Bar” and set “Tab Bar Placement” to “Left”. Note: You can achieve the same effect by setting the “Tab Bar Placement” to “Right”. With the “Speed Dial” visible you will be able to see your wallpaper with ease. While this is obviously not for everyone it does make for a great visual trick. Portable Versions Perhaps you need this wonderful new version of Opera to go with you wherever you do during the day. Not a problem…just visit the Opera USB website to choose a version that works best for you. You can select from “Zip or Exe” setup files and if needed update an older portable version using a “Zipped Update Files Package”. If you are updating an older version keep in mind that you will need to delete the old “OperaUSB.exe. File” due to changes with the new setup files. During our tests updating older portable versions went well for the most part but we did experience a few “odd UI quirks” here and there…so we recommend setting up a clean install if possible. Conclusion The new 10.50 release is a pleasure to use and is a recommended install for your system. Whether you are considering trying Opera for the first time or have been using it for a bit we think that you will pleased with everything that the 10.50 release has to offer.

  • Using Unity – Part 1

    - by nmarun
    I have been going through implementing some IoC pattern using Unity and so I decided to share my learnings (I know that’s not an English word, but you get the point). Ok, so I have an ASP.net project named ProductWeb and a class library called ProductModel. In the model library, I have a class called Product: 1: public class Product 2: { 3: public string Name { get; set; } 4: public string Description { get; set; } 5:  6: public Product() 7: { 8: Name = "iPad"; 9: Description = "Not just a reader!"; 10: } 11:  12: public string WriteProductDetails() 13: { 14: return string.Format("Name: {0} Description: {1}", Name, Description); 15: } 16: } In the Page_Load event of the default.aspx, I’ll need something like: 1: Product product = new Product(); 2: productDetailsLabel.Text = product.WriteProductDetails(); Now, let’s go ‘Unity’fy this application. I assume you have all the bits for the pattern. If not, get it from here. I found this schematic representation of Unity pattern from the above link. This image might not make much sense to you now, but as we proceed, things will get better. The first step to implement the Inversion of Control pattern is to create interfaces that your types will implement. An IProduct interface is added to the ProductModel project. 1: public interface IProduct 2: { 3: string WriteProductDetails(); 4: } Let’s make our Product class to implement the IProduct interface. The application will compile and run as before despite the changes made. Add the following references to your web project: Microsoft.Practices.Unity Microsoft.Practices.Unity.Configuration Microsoft.Practices.Unity.StaticFactory Microsoft.Practices.ObjectBuilder2 We need to add a few lines to the web.config file. The line below tells what version of Unity pattern we’ll be using. 1: <configSections> 2: <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> 3: </configSections> Add another block with the same name as the section name declared above – ‘unity’. 1: <unity> 2: <typeAliases> 3: <!--Custom object types--> 4: <typeAlias alias="IProduct" type="ProductModel.IProduct, ProductModel"/> 5: <typeAlias alias="Product" type="ProductModel.Product, ProductModel"/> 6: </typeAliases> 7: <containers> 8: <container name="unityContainer"> 9: <types> 10: <type type="IProduct" mapTo="Product"/> 11: </types> 12: </container> 13: </containers> 14: </unity> From the Unity Configuration schematic shown above, you see that the ‘unity’ block has a ‘typeAliases’ and a ‘containers’ segment. The typeAlias element gives a ‘short-name’ for a type. This ‘short-name’ can be used to point to this type any where in the configuration file (web.config in our case, but all this information could be coming from an external xml file as well). The container element holds all the mapping information. This container is referenced through its name attribute in the code and you can have multiple of these container elements in the containers segment. The ‘type’ element in line 10 basically says: ‘When Unity requests to resolve the alias IProduct, return an instance of whatever the short-name of Product points to’. This is the most basic piece of Unity pattern and all of this is accomplished purely through configuration. So, in future you have a change in your model, all you need to do is - implement IProduct on the new model class and - either add a typeAlias for the new type and point the mapTo attribute to the new alias declared - or modify the mapTo attribute of the type element to point to the new alias (as the case may be). Now for the calling code. It’s a good idea to store your unity container details in the Application cache, as this is rarely bound to change and also adds for better performance. The Global.asax.cs file comes for our rescue: 1: protected void Application_Start(object sender, EventArgs e) 2: { 3: // create and populate a new Unity container from configuration 4: IUnityContainer unityContainer = new UnityContainer(); 5: UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); 6: section.Containers["unityContainer"].Configure(unityContainer); 7: Application["UnityContainer"] = unityContainer; 8: } 9:  10: protected void Application_End(object sender, EventArgs e) 11: { 12: Application["UnityContainer"] = null; 13: } All this says is: create an instance of UnityContainer() and read the ‘unity’ section from the configSections segment of the web.config file. Then get the container named ‘unityContainer’ and store it in the Application cache. In my code-behind file, I’ll make use of this UnityContainer to create an instance of the Product type. 1: public partial class _Default : Page 2: { 3: private IUnityContainer unityContainer; 4: protected void Page_Load(object sender, EventArgs e) 5: { 6: unityContainer = Application["UnityContainer"] as IUnityContainer; 7: if (unityContainer == null) 8: { 9: productDetailsLabel.Text = "ERROR: Unity Container not populated in Global.asax.<p />"; 10: } 11: else 12: { 13: IProduct productInstance = unityContainer.Resolve<IProduct>(); 14: productDetailsLabel.Text = productInstance.WriteProductDetails(); 15: } 16: } 17: } Looking the ‘else’ block, I’m asking the unityContainer object to resolve the IProduct type. All this does, is to look at the matching type in the container, read its mapTo attribute value, get the full name from the alias and create an instance of the Product class. Fabulous!! I’ll go more in detail in the next blog. The code for this blog can be found here.

  • Behind ASP.NET MVC Mock Objects

    - by imran_ku07
       Introduction:           I think this sentence now become very familiar to ASP.NET MVC developers that "ASP.NET MVC is designed with testability in mind". But what ASP.NET MVC team did for making applications build with ASP.NET MVC become easily testable? Understanding this is also very important because it gives you some help when designing custom classes. So in this article i will discuss some abstract classes provided by ASP.NET MVC team for the various ASP.NET intrinsic objects, including HttpContext, HttpRequest, and HttpResponse for making these objects as testable. I will also discuss that why it is hard and difficult to test ASP.NET Web Forms.      Description:           Starting from Classic ASP to ASP.NET MVC, ASP.NET Intrinsic objects is extensively used in all form of web application. They provide information about Request, Response, Server, Application and so on. But ASP.NET MVC uses these intrinsic objects in some abstract manner. The reason for this abstraction is to make your application testable. So let see the abstraction.           As we know that ASP.NET MVC uses the same runtime engine as ASP.NET Web Form uses, therefore the first receiver of the request after IIS and aspnet_filter.dll is aspnet_isapi.dll. This will start the application domain. With the application domain up and running, ASP.NET does some initialization and after some initialization it will call Application_Start if it is defined. Then the normal HTTP pipeline event handlers will be executed including both HTTP Modules and global.asax event handlers. One of the HTTP Module is registered by ASP.NET MVC is UrlRoutingModule. The purpose of this module is to match a route defined in global.asax. Every matched route must have IRouteHandler. In default case this is MvcRouteHandler which is responsible for determining the HTTP Handler which returns MvcHandler (which is derived from IHttpHandler). In simple words, Route has MvcRouteHandler which returns MvcHandler which is the IHttpHandler of current request. In between HTTP pipeline events the handler of ASP.NET MVC, MvcHandler.ProcessRequest will be executed and shown as given below,          void IHttpHandler.ProcessRequest(HttpContext context)          {                    this.ProcessRequest(context);          }          protected virtual void ProcessRequest(HttpContext context)          {                    // HttpContextWrapper inherits from HttpContextBase                    HttpContextBase ctxBase = new HttpContextWrapper(context);                    this.ProcessRequest(ctxBase);          }          protected internal virtual void ProcessRequest(HttpContextBase ctxBase)          {                    . . .          }             HttpContextBase is the base class. HttpContextWrapper inherits from HttpContextBase, which is the parent class that include information about a single HTTP request. This is what ASP.NET MVC team did, just wrap old instrinsic HttpContext into HttpContextWrapper object and provide opportunity for other framework to provide their own implementation of HttpContextBase. For example           public class MockHttpContext : HttpContextBase          {                    . . .          }                     As you can see, it is very easy to create your own HttpContext. That's what did the third party mock frameworks like TypeMock, Moq, RhinoMocks, or NMock2 to provide their own implementation of ASP.NET instrinsic objects classes.           The key point to note here is the types of ASP.NET instrinsic objects. In ASP.NET Web Form and ASP.NET MVC. For example in ASP.NET Web Form the type of Request object is HttpRequest (which is sealed) and in ASP.NET MVC the type of Request object is HttpRequestBase. This is one of the reason that makes test in ASP.NET WebForm is difficult. because their is no base class and the HttpRequest class is sealed, therefore it cannot act as a base class to others. On the other side ASP.NET MVC always uses a base class to give a chance to third parties and unit test frameworks to create thier own implementation ASP.NET instrinsic object.           Therefore we can say that in ASP.NET MVC, instrinsic objects are of type base classes (for example HttpContextBase) .Actually these base classes had it's own implementation of same interface as the intrinsic objects it abstracts. It includes only virtual members which simply throws an exception. ASP.NET MVC also provides the corresponding wrapper classes (for example, HttpRequestWrapper) which provides a concrete implementation of the base classes in the form of ASP.NET intrinsic object. Other wrapper classes may be defined by third parties in the form of a mock object for testing purpose.           So we can say that a Request object in ASP.NET MVC may be HttpRequestWrapper or may be MockRequestWrapper(assuming that MockRequestWrapper class is used for testing purpose). Here is list of ASP.NET instrinsic and their implementation in ASP.NET MVC in the form of base and wrapper classes. Base Class Wrapper Class ASP.NET Intrinsic Object Description HttpApplicationStateBase HttpApplicationStateWrapper Application HttpApplicationStateBase abstracts the intrinsic Application object HttpBrowserCapabilitiesBase HttpBrowserCapabilitiesWrapper HttpBrowserCapabilities HttpBrowserCapabilitiesBase abstracts the HttpBrowserCapabilities class HttpCachePolicyBase HttpCachePolicyWrapper HttpCachePolicy HttpCachePolicyBase abstracts the HttpCachePolicy class HttpContextBase HttpContextWrapper HttpContext HttpContextBase abstracts the intrinsic HttpContext object HttpFileCollectionBase HttpFileCollectionWrapper HttpFileCollection HttpFileCollectionBase abstracts the HttpFileCollection class HttpPostedFileBase HttpPostedFileWrapper HttpPostedFile HttpPostedFileBase abstracts the HttpPostedFile class HttpRequestBase HttpRequestWrapper Request HttpRequestBase abstracts the intrinsic Request object HttpResponseBase HttpResponseWrapper Response HttpResponseBase abstracts the intrinsic Response object HttpServerUtilityBase HttpServerUtilityWrapper Server HttpServerUtilityBase abstracts the intrinsic Server object HttpSessionStateBase HttpSessionStateWrapper Session HttpSessionStateBase abstracts the intrinsic Session object HttpStaticObjectsCollectionBase HttpStaticObjectsCollectionWrapper HttpStaticObjectsCollection HttpStaticObjectsCollectionBase abstracts the HttpStaticObjectsCollection class      Summary:           ASP.NET MVC provides a set of abstract classes for ASP.NET instrinsic objects in the form of base classes, allowing someone to create their own implementation. In addition, ASP.NET MVC also provide set of concrete classes in the form of wrapper classes. This design really makes application easier to test and even application may replace concrete implementation with thier own implementation, which makes ASP.NET MVC very flexable.

  • Compiling examples for consuming the REST Endpoints for WCF Service using Agatha

    - by REA_ANDREW
    I recently made two contributions to the Agatha Project by Davy Brion over on Google Code, and one of the things I wanted to follow up with was a post showing examples and some, seemingly required tid bits.  The contributions which I made where: To support StructureMap To include REST (JSON and XML) support for the service contract The examples which I have made, I want to format them so they fit in with the current format of examples over on Agatha and hopefully create and submit a third patch which will include these examples to help others who wish to use these additions. Whilst building these examples for both XML and JSON I have learnt a couple of things which I feel are not really well documented, but are extremely good practice and once known make perfect sense.  I have chosen a real basic e-commerce context for my example Requests and Responses, and have also made use of the excellent tool AutoMapper, again on Google Code. Setting the scene I have followed the Pipes and Filters Pattern with the IQueryable interface on my Repository and exposed the following methods to query Products: IQueryable<Product> GetProducts(); IQueryable<Product> ByCategoryName(this IQueryable<Product> products, string categoryName) Product ByProductCode(this IQueryable<Product> products, String productCode) I have an interface for the IProductRepository but for the concrete implementation I have simply created a protected getter which populates a private List<Product> with 100 test products with random data.  Another good reason for following an interface based approach is that it will demonstrate usage of my first contribution which is the StructureMap support.  Finally the two Domain Objects I have made are Product and Category as shown below: public class Product { public String ProductCode { get; set; } public String Name { get; set; } public Decimal Price { get; set; } public Decimal Rrp { get; set; } public Category Category { get; set; } }   public class Category { public String Name { get; set; } }   Requirements for the REST Support One of the things which you will notice with Agatha is that you do not have to decorate your Request and Response objects with the WCF Service Model Attributes like DataContract, DataMember etc… Unfortunately from what I have seen, these are required if you want the same types to work with your REST endpoint.  I have not tried but I assume the same result can be achieved by simply decorating the same classes with the Serializable Attribute.  Without this the operation will fail. Another surprising thing I have found is that it did not work until I used the following Attribute parameters: Name Namespace e.g. [DataContract(Name = "GetProductsRequest", Namespace = "AgathaRestExample.Service.Requests")] public class GetProductsRequest : Request { }   Although I was surprised by this, things kind of explained themselves when I got round to figuring out the exact construct required for both the XML and the REST.  One of the things which you already know and are then reminded of is that each of your Requests and Responses ultimately inherit from an abstract base class respectively. This information needs to be represented in a way native to the format being used.  I have seen this in XML but I have not seen the format which is required for the JSON. JSON Consumer Example I have used JQuery to create the example and I simply want to make two requests to the server which as you will know with Agatha are transmitted inside an array to reduce the service calls.  I have also used a tool called json2 which is again over at Google Code simply to convert my JSON expression into its string format for transmission.  You will notice that I specify the type of Request I am using and the relevant Namespace it belongs to.  Also notice that the second request has a parameter so each of these two object are representing an abstract Request and the parameters of the object describe it. <script type="text/javascript"> var bodyContent = $.ajax({ url: "http://localhost:50348/service.svc/json/processjsonrequests", global: false, contentType: "application/json; charset=utf-8", type: "POST", processData: true, data: JSON.stringify([ { __type: "GetProductsRequest:AgathaRestExample.Service.Requests" }, { __type: "GetProductsByCategoryRequest:AgathaRestExample.Service.Requests", CategoryName: "Category1" } ]), dataType: "json", success: function(msg) { alert(msg); } }).responseText; </script>   XML Consumer Example For the XML Consumer example I have chosen to use a simple Console Application and make a WebRequest to the service using the XML as a request.  I have made a crude static method which simply reads from an XML File, replaces some value with a parameter and returns the formatted XML.  I say crude but it simply shows how XML Templates for each type of Request could be made and then have a wrapper utility in whatever language you use to combine the requests which are required.  The following XML is the same Request array as shown above but simply in the XML Format. <?xml version="1.0" encoding="utf-8" ?> <ArrayOfRequest xmlns="http://schemas.datacontract.org/2004/07/Agatha.Common" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <Request i:type="a:GetProductsRequest" xmlns:a="AgathaRestExample.Service.Requests"/> <Request i:type="a:GetProductsByCategoryRequest" xmlns:a="AgathaRestExample.Service.Requests"> <a:CategoryName>{CategoryName}</a:CategoryName> </Request> </ArrayOfRequest>   It is funny because I remember submitting a question to StackOverflow asking whether there was a REST Client Generation tool similar to what Microsoft used for their RestStarterKit but which could be applied to existing services which have REST endpoints attached.  I could not find any but this is now definitely something which I am going to build, as I think it is extremely useful to have but also it should not be too difficult based on the information I now know about the above.  Finally I thought that the Strategy Pattern would lend itself really well to this type of thing so it can accommodate for different languages. I think that is about it, I have included the code for the example Console app which I made below incase anyone wants to have a mooch at the code.  As I said above I want to reformat these to fit in with the current examples over on the Agatha project, but also now thinking about it, make a Documentation Web method…{brain ticking} :-) Cheers for now and here is the final bit of code: static void Main(string[] args) { var request = WebRequest.Create("http://localhost:50348/service.svc/xml/processxmlrequests"); request.Method = "POST"; request.ContentType = "text/xml"; using(var writer = new StreamWriter(request.GetRequestStream())) { writer.WriteLine(GetExampleRequestsString("Category1")); } var response = request.GetResponse(); using(var reader = new StreamReader(response.GetResponseStream())) { Console.WriteLine(reader.ReadToEnd()); } Console.ReadLine(); } static string GetExampleRequestsString(string categoryName) { var data = File.ReadAllText(Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "ExampleRequests.xml")); data = data.Replace("{CategoryName}", categoryName); return data; } }

  • Conversation as User Assistance

    - by ultan o'broin
    Applications User Experience members (Erika Web, Laurie Pattison, and I) attended the User Assistance Europe Conference in Stockholm, Sweden. We were impressed with the thought leadership and practical application of ideas in Anne Gentle's keynote address "Social Web Strategies for Documentation". After the conference, we spoke with Anne to explore the ideas further. Anne Gentle (left) with Applications User Experience Senior Director Laurie Pattison In Anne's book called Conversation and Community: The Social Web for Documentation, she explains how user assistance is undergoing a seismic shift. The direction is away from the old print manuals and online help concept towards a web-based, user community-driven solution using social media tools. User experience professionals now have a vast range of such tools to start and nurture this "conversation": blogs, wikis, forums, social networking sites, microblogging systems, image and video sharing sites, virtual worlds, podcasts, instant messaging, mashups, and so on. That user communities are a rich source of user assistance is not a surprise, but the extent of available assistance is. For example, we know from the Consortium for Service Innovation that there has been an 'explosion' of user-generated content on the web. User-initiated community conversations provide as much as 30 times the number of official help desk solutions for consortium members! The growing reliance on user community solutions is clearly a user experience issue. Anne says that user assistance as conversation "means getting closer to users and helping them perform well. User-centered design has been touted as one of the most important ideas developed in the last 20 years of workplace writing. Now writers can take the idea of user-centered design a step further by starting conversations with users and enabling user assistance in interactions." Some of Anne's favorite examples of this paradigm shift from the world of traditional documentation to community conversation include: Writer Bob Bringhurst's blog about Adobe InDesign and InCopy products and Adobe's community help The Microsoft Development Network Community Center ·The former Sun (now Oracle) OpenDS wiki, NetBeans Ruby and other community approaches to engage diverse audiences using screencasts, wikis, and blogs. Cisco's customer support wiki, EMC's community, as well as Symantec and Intuit's approaches The efforts of Ubuntu, Mozilla, and the FLOSS community generally Adobe Writer Bob Bringhurst's Blog Oracle is not without a user community conversation too. Besides the community discussions and blogs around documentation offerings, we have the My Oracle Support Community forums, Oracle Technology Network (OTN) communities, wiki, blogs, and so on. We have the great work done by our user groups and customer councils. Employees like David Haimes reach out, and enthusiastic non-employee gurus like Chet Justice (OracleNerd), Floyd Teter and Eddie Awad provide great "how-to" information too. But what does this paradigm shift mean for existing technical writers as users turn away from the traditional printable PDF manual deliverables? We asked Anne after the conference. The writer role becomes one of conversation initiator or enabler. The role evolves, along with the process, as the users define their concept of user assistance and terms of engagement with the product instead of having it pre-determined. It is largely a case now of "inventing the job while you're doing it, instead of being hired for it" Anne said. There is less emphasis on formal titles. Anne mentions that her own title "Content Stacker" at OpenStack; others use titles such as "Content Curator" or "Community Lead". However, the role remains one essentially about communications, "but of a new type--interacting with users, moderating, curating content, instead of sitting down to write a manual from start to finish." Clearly then, this role is open to more than professional technical writers. Product managers who write blogs, developers who moderate forums, support professionals who update wikis, rock star programmers with a penchant for YouTube are ideal. Anyone with the product knowledge, empathy for the user, and flair for relationships on the social web can join in. Some even perform these roles already but do not realize it. Anne feels the technical communicator space will move from hiring new community conversation professionals (who are already active in the space through blogging, tweets, wikis, and so on) to retraining some existing writers over time. Our own research reveals that the established proponents of community user assistance even set employee performance objectives for internal content curators about the amount of community content delivered by people outside the organization! To take advantage of the conversations on the web as user assistance, enterprises must first establish where on the spectrum their community lies. "What is the line between community willingness to contribute and the enterprise objectives?" Anne asked. "The relationship with users must be managed and also measured." Anne believes that the process can start with a "just do it" approach. Begin by reaching out to existing user groups, individual bloggers and tweeters, forum posters, early adopter program participants, conference attendees, customer advisory board members, and so on. Use analytical tools to measure the level of conversation about your products and services to show a return on investment (ROI), winning management support. Anne emphasized that success with the community model is dependent on lowering the technical and motivational barriers so that users can readily contribute to the conversation. Simple tools must be provided, and guidelines, if any, must be straightforward but not mandatory. The conversational approach is one where traditional style and branding guides do not necessarily apply. Tools and infrastructure help users to create content easily, to search and find the information online, read it, rate it, translate it, and participate further in the content's evolution. Recognizing contributors by using ratings on forums, giving out Twitter kudos, conference invitations, visits to headquarters, free products, preview releases, and so on, also encourages the adoption of the conversation model. The move to conversation as user assistance is not free, but there is a business ROI. The conversational model means that customer service is enhanced, as user experience moves from a functional to a valued, emotional level. Studies show a positive correlation between loyalty and financial performance (Consortium for Service Innovation, 2010), and as customer experience and loyalty become key differentiators, user experience professionals cannot explore the model's possibilities. The digital universe (measured at 1.2 million petabytes in 2010) is doubling every 12 to 18 months, and 70 percent of that universe consists of user-generated content (IDC, 2010). Conversation as user assistance cannot be ignored but must be embraced. It is a time to manage for abundance, not scarcity. Besides, the conversation approach certainly sounds more interesting, rewarding, and fun than the traditional model! I would like to thank Anne for her time and thoughts, and recommend that all user assistance professionals read her book. You can follow Anne on Twitter at: http://www.twitter.com/annegentle.
