• SSDT - What's in a name?

  - by jamiet

  SQL Server Data Tools (SSDT) recently got released as part of SQL Server 2012 and depending on who you believe it can be described as either: a suite of tools for building SQL Server database solutions or a suite of tools for building SQL Server database, Integration Services, Analysis Services & Reporting Services solutions Certainly the SQL Server 2012 installer seems to think it is the latter because it describes SQL Server Data Tools as "the SQL server development environment, including the tool formerly named Business Intelligence Development Studio. Also installs the business intelligence tools and references to the web installers for database development tools" as you can see here: Strange then that, seemingly, there is no consensus within Microsoft about what SSDT actually is. On yesterday's blog post First Release of SSDT Power Tools reader Simon Lampen asked the quite legitimate question:I understand (rightly or wrongly) that SSDT is the replacement for BIDS for SQL 2012 and have just installed this. If this is the case can you please point me to how I can edit rdl and rdlc files from within Visual Studio 2010 and import MS Access reports.To which came the following reply:SSDT doesn't include any BIDs (sic) components. Following up with the appropriate team (Analysis Services, Reporting Services, Integration Services) via their forum or msdn page would be the best way to answer you questions about these kinds of services. That's from a Microsoft employee by the way. Simon is even more confused by this and replies with:I have done some more digging and am more confused than ever. This documentation (and many others) : msdn.microsoft.com/.../ms156280.aspx expressly states that SSDT is where report editing tools are to be foundAnd on it goes....You can see where Simon's confusion stems from. He has official documentation stating that SSDT includes all the stuff for building SSIS/SSAS/SSRS solutions (this is confirmed in the installer, remember) yet someone from Microsoft tells him "SSDT doesn't include any BIDs components".I have been close to this for a long time (all the way through the CTPs) so I can kind of understand where the confusion stems from. To my understanding SSDT was originally the name of the database dev stuff but eventually that got expanded to include all of the dev tools - I guess not everyone in Microsoft got the memo.Does this sound familiar? Have we not been down this road before? The database dev tools have had upteen names over the years (do any of datadude, TSData, VSTS for DB Pros, DBPro, VS2010 Database Projects sound familiar) and I was hoping that the SSDT moniker would put all confusion to bed - evidently its as complicated now as it has ever been.Forgive me for whinging but putting meaningful, descriptive, accurate, well-defined and easily-communicated names onto a product doesn't seem like a difficult thing to do. I guess I'm mistaken!Onwards and upwards...@Jamiet

• How can fix HDMI HDTV overscan when I my TV has no aspect ratio setting?

  - by Colin Dean

  I have a 32" Vizio HDTV. It's a few years old, but running well. I just connected a new nettop to it using HDMI out. It's the Intel 3x00 graphics chipset. I'm seeing overscan, where the resolution in Ubuntu is set to 1280x720, but the TV itself is 1366x768. When I go into the Monitors control applet, I cannot change the resolution to anything other than the current or 640x480. A user had a similar overscan problem, but fixed the overscan by adjusting his TV's aspect ratio settings. I do not have that luxury. Is there a way I can do this without having to delve into xorg.conf or other command-line craziness? I'm more than comfortable doing so, but there must be a cleaner way. I'm running Ubuntu Natty, keeping up with updates and such. Here's the output of lspci: colin@bricktop:~$ lspci 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 12) 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) 00:04.0 Signal processing controller: Intel Corporation Core Processor Thermal Management Controller (rev 12) 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series Chipset HECI Controller (rev 06) 00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 (rev 06) 00:1c.1 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 2 (rev 06) 00:1c.2 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 3 (rev 06) 00:1d.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev a6) 00:1f.0 ISA bridge: Intel Corporation Mobile 5 Series Chipset LPC Interface Controller (rev 06) 00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 4 port SATA AHCI Controller (rev 06) 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus Controller (rev 06) 00:1f.6 Signal processing controller: Intel Corporation 5 Series/3400 Series Chipset Thermal Subsystem (rev 06) 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Using SQL Source Control and Vault Professional Part 4

  - by Ajarn Mark Caldwell

  Two weeks ago I upgraded our installation of Fortress to the latest version, which is now named Vault Professional.  This is the version of Vault (i.e. Vault Standard 5.1 / Vault Professional 5.1) that will be officially supported with Red-Gate SQL Source Control 2.1.  While the folks at Red-Gate did a fantastic job of working with me to get SQL Source Control to work with the older Fortress version, we weren’t going to just sit on that.  There are a couple of things that Vault Professional cleaned up for us, such as improved integration with Visual Studio 2010, so it was a win all around. Shortly after that upgrade, I received notice from Red-Gate that they had a new Early Access version of SQL Source Control available that included the ability to source control static data.  The idea here is that you probably have a few fairly static lookup tables in your system, and those data values are similar in concept to source code, and should be versioned in your source control management system also.  I agree with this, but please be wise…somebody out there is bound to try to use this feature as their disaster recovery for their entire database, and that is NOT the purpose.  First off, you should never have your PROD (or LIVE, whatever you call it) system attached to source control.  Source Control is for development, not for PROD systems.  Second, use the features that are intended for this purpose, such as BACKUP and RESTORE. Laying that tangent aside, it is great that now you can include these critical values in your repository and make them part of a deployment process.  As you would guess, SQL Source Control uses SQL Data Compare to create the data change scripts just like it uses SQL Compare to create the schema change scripts.  Once again, they did a very good job with the integration to their other products.  At this point we are really starting to see some good payback on our investment in the full SQL Developer Bundle.  Those products were worth the investment back when we only used them sporadically for troubleshooting and DBA analysis, but now with SQL Source Control, they are becoming everyday-use products for the development team. I like this software (SQL Source Control) so much that I am about to break my own rules and distribute it to my team to use even though it is still in beta.  This is the first time that I have approved the use of any beta software in a production scenario (actively building our next versions of internal software) but I predict that the usability and productivity gain of using SQL Source Control over manual scripting is worth the risk.  Of course, I have also put this beta software through its paces pretty well to be comfortable with it, and Red-Gate has proven their responsiveness to issues that came up in my early beta testing, and so I am willing to bet on their continued support.  Likewise, SourceGear, the maker of Vault Professional, has proven itself to me as well, and so the combination of SQL Source Control with Vault Professional is the new standard for my development team.

• VSDB to SSDT part 4 : Redistributable database deployment package with SqlPackage.exe

  - by Etienne Giust

  The goal here is to use SSDT SqlPackage to deploy the output of a Visual Studio 2012 Database project… a bit in the same fashion that was detailed here : http://geekswithblogs.net/80n/archive/2012/09/12/vsdb-to-ssdt-part-3--command-line-deployment-with-sqlpackage.exe.aspx   The difference is we want to do it on an environment where Visual Studio 2012 and SSDT are not installed. This might be the case of your Production server.   Package structure So, to get started you need to create a folder named “DeploymentSSDTRedistributable”. This folder will have the following structure :         The dacpac and dll files are the outputs of your Visual Studio 2012 Database project. If your database project references another database project, you need to put their dacpac and dll here too, otherwise deployment will not work. The publish.xml file is the publish configuration suitable for your target environment. It holds connexion strings, SQLVARS parameters and deployment options. Review it carefully. The SqlDacRuntime folder (an arbitrary chosen name) will hold the SqlPackage executable and supporting libraries   Contents of the SqlDacRuntime folder Here is what you need to put in the SqlDacRuntime folder  :      You will be able to find these files in the following locations, on a machine with Visual Studio 2012 Ultimate installed : C:\Program Files (x86)\Microsoft SQL Server\110\DAC\bin : SqlPackage.exe Microsoft.Data.Tools.Schema.Sql.dll  Microsoft.Data.Tools.Utilities.dll Microsoft.SqlServer.Dac.dll C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.SqlServer.TransactSql.ScriptDom\v4.0_11.0.0.0__89845dcd8080cc91 Microsoft.SqlServer.TransactSql.ScriptDom.dll   Deploying   Now take your DeploymentSSDTRedistributable deployment package to your remote machine. In a standard command window, place yourself inside the DeploymentSSDTRedistributable  folder.   You can first perform a check of what will be updated in the target database. The DeployReport task of SqlPackage.exe will help you do that. The following command will output an xml of the changes:   "SqlDacRuntime/SqlPackage.exe" /Action:DeployReport /SourceFile:./Our.Database.dacpac /Profile:./Release.publish.xml /OutputPath:./ChangesToDeploy.xml      You might get some warnings on Log and Data file like I did. You can ignore them. Also, the tool is warning about data loss when removing a column from a table. By default, the publish.xml options will prevent you from deploying when data loss is occuring (see the BlockOnPossibleDataLoss inside the publish.xml file). Before actual deployment, take time to carefully review the changes to be applied in the ChangesToDeploy.xml file.    When you are satisfied, you can deploy your changes with the following command : "SqlDacRuntime/SqlPackage.exe" /Action:Publish /SourceFile:./Our.Database.dacpac /Profile:./Release.publish.xml   Et voilà !  Your dacpac file has been deployed to your database. I’ve been testing this on a SQL 2008 Server (not R2) but it should work on 2005, 2008 R2 and 2012 as well.   Many thanks to Anuj Chaudhary for his article on the subject : http://www.anujchaudhary.com/2012/08/sqlpackageexe-automating-ssdt-deployment.html

• ath9k driver does not weak up

  - by shantanu

  I know this is common question but i found no suitable answer, so i am asking this again. I installed ubuntu 11.10. I found the bug for ath9k, so set first network boot from BIOS menu. That's worked. I have upgraded to 12.04 yesterday. Now ath9k is creating problem again. First network boot is still enable. ath9k works at start. But failed(connect again and again) after couple of minutes. dmesg show error that it can not weak up in 500us. So i tried #compat-wireless-3.5.1-1. But result is same.

• ATI Radeon HD 4650 AGP Video card not recognized properly

  - by PastorLarry

  I have an ASUS ATI Radeon HD 4650 AGP in this system (yeah, I know how old it is). I've been on Ubuntu since 10.04, and the system has never properly recognized the card. I have always had the VESA drivers installed. Now that I have the time to address the problem, 12.04 was listing the card as "Unknown" under the System Settings. Meanwhile, Sysinfo recognizes the card as: Advanced Micro Devices [AMD] nee ATI RV730 Pro AGP [Radeon HD 4600 Series] (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Device 0028 So I know that this card should be using the radeon driver (or even the radeonhd driver). However, when I installed the mesa-utils package, the card is suddenly reported as: Gallium 0.4 on llvmpipe (LLVM 0x300) So now, I'm completely at a loss. It seems that the llvmpipe stuff has to do with OpenGL, but it still appears that I don't have the proper video driver installed. That being said, anyone know what I can do to force the system to recognize the card and use the radeon driver? [EDIT 05.28] I did look at some other information, including glxinfo and a couple of other commands (it was REALLY late, so I don't remember the other commands) and I got these: glxinfo | grep vendor: server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: X.org glxinfo | grep renderer: OpenGL renderer string: Gallium 0.4 on AMD RV730 One of the other commands gave a whole lot of info and near the end stated that the activation string for the radeon driver was "modprobe radeon". I've tried that from sudo and as root, but it doesn't seem to change anything. I'm at a complete loss. I've even added the xorg-edgers ppa to my Software Sources and updated and rebooted the system, but nothing has changed. Most of all, I can't seem to find any documentation on this issue, as it seems that it's assumed that the radeon driver will install automatically, no questions asked. I feel like such a newbie. Does anyone have any ideas on this? [edit 05.28] results of lsmod | grep radeon (in a more readable format than the comment below): radeon 733693 3 ttm 65344 1 radeon drm_kms_helper 45466 1 radeon drm 197692 5 radeon,ttm,drm_kms_helper i2c_algo_bit 13199 1 radeon [edit 05.29] This is my /etc/X11/xorg.conf: Section "ServerLayout" Identifier "aticonfig Layout" Screen 0 "aticonfig-Screen[0]-0" 0 0 EndSection Section "Module" EndSection Section "Monitor" Identifier "aticonfig-Monitor[0]-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" So here is my question. Can I simply change the name of the driver in the device section to "radeon" instead of "fglrx" and have the radeon driver work? Or is ther a way to use this as a tmeplate and change the appropriate lines and activate the radeon driver through this file?

• How do I get my blacked out ttys back?

  - by con-f-use

  Original Question: After I replaced my Ubuntu 10.10 with 11.04 all I get when I Strg+Alt+F1-6 into a tty is a black screen. Also when I boot there's a while of black screen after grub2 menu is displayed. Then until just before gnome starts it stays black. I have an Nvida Geforce Quadro FX 770M on my HP EliteBook 8530w. How do I get my ttys (aka 'virtual terminals') to work again? My effords in chronological order: So grub and gfx-payload seems to be the problem, I figured. I went along with this guide for higher tty resolution. Which led to the grub2 menu displaying in my native resolution rather than 800x600. The black screen problem remains. I googlehit some bugreports on other nvidia crads having that problem. I tried uninstalling the nvidia driver. No effect. Also tried different resolutions With an older version of the kernel it works. Though not perfectly. The ttys are usable, black screen between grub2 menu and gnome start remains. Not really a solution. Tried so much, that I lost track. Reinstalled grub2 and linux-image-2.6.38-8-generic. Then did this to my /etc/default/grub in accordance with the aforementioned guide (/etc/grub.d/00_header edited as well): GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 #GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=3 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` #GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_GFXMODE=1680x1050x32 To my surprise I can now use my ttys in native resolution. Black screen between grub2 menu and gnome login screen is still there though. That is annoying since I also use an encrypted disk thus having to enter my passphrase in total dark... Still looking for a solution but urgency is low. Downloaded and installed a later version of nvidia driver. No difference to last edit. Tried GRUB_CMDLINE_LINUX="vga="-parameter. No effect. nomodeset has no effect. not even in combination with vga=... Tried echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash no effect (see comment) On the verge of resignation... Bounty period soon to end.

• Installing Canon LBP6000 in Ubuntu 12.04

  - by MMA

  This is really frustrating. I am trying to install LBP6000 in Ubuntu 12.04 without any success. (Well, I had success about a week back when I first bought the printer and finally printed pages after a struggle of several hours. Then today it suddenly stopped working and I uninstalled everything and started from scratch. Now, I seem to have lost the way.) My steps Downloaded the latest Canon driver from Canon site. File Linux_CAPT_PrinterDriver_V240_uk_EN.tar.gz Got the radu script (I am allowed only two hyperlinks, so can not put the link here. You can Google radu Canon) Changed the /etc/modprobe.d/blacklist-cups-usblp.conf file as instructed in, Official Documentation. (See the section Ubuntu 12.04 Install). Now this file looks like, # cups talks to the raw USB devices, so we need to blacklist usblp to avoid # grabbing them # blacklist usblp Rebooted my machine Changed the port in radu script to 59787 as instructed in the link at step 3. (Again see the section Ubuntu 12.04 Install, or see the comment at How to Install Canon LBP Printers in Ubuntu. Also put the latest deb files from step 1 in the appropriate directory of this script. Ran the radu script. A printer, LBP6000 got added. Not two printers, one to be disabled, as appeared in the message on the terminal after running the script. sudo /etc/init.d/ccpd status shows, Canon Printer Daemon for CUPS: ccpd: 3142 3139 Results The printer does not print. Printer state (from System Setting-Printing, or at cups http interface localhost:631/printers/LBP6000) goes from Idle to Processing, a job appears in print queue, and then the job disappears and the printer state goes back to Idle. The actual printer does not even blink. Diagnostics (got help from the link in step 3, Troubleshooting) captstatusui -P LBP6000 shows communication error lsmod | grep usblp did not show anything. After running, sudo modprobe usblp, shows usblp 17885 0 However, ls -l /dev/usb/lp0 gives, ls: cannot access /dev/usb/lp0: No such file or directory /var/ccpd did not exist, created, sudo mkdir /var/ccpd sudo mkfifo /var/ccpd/fifo0 sudo chown -R lp:lp /var/ccpd Any suggestion will be appreciated.

• SQL SERVER – Quiz and Video – Introduction to Basics of a Query Hint

  - by pinaldave

  This blog post is inspired from SQL Architecture Basics Joes 2 Pros: Core Architecture concepts – SQL Exam Prep Series 70-433 – Volume 3. [Amazon] | [Flipkart] | [Kindle] | [IndiaPlaza] This is follow up blog post of my earlier blog post on the same subject - SQL SERVER – Introduction to Basics of a Query Hint – A Primer. In the article we discussed various basics terminology of the query hints. The article further covers following important concepts of query hints. Expecting Seek and getting a Scan Creating an index for improved optimization Implementing the query hint Above three are the most important concepts related to query hint and SQL Server.  There are many more things one has to learn but without beginners fundamentals one can’t learn the advanced  concepts. Let us have small quiz and check how many of you get the fundamentals right. Quiz 1) You have the following query: DECLARE @UlaChoice TinyInt SET @Type = 1 SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice You have a nonclustered index named IX_Legal_Ula on the UlaChoice field. The Primary key is on the ID field and called PK_Legal_ID 99% of the time the value of the @UlaChoice is set to ‘YP101′. What query will achieve the best optimization for this query? SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice WITH(INDEX(X_Legal_Ula)) SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice WITH(INDEX(PK_Legal_ID)) SELECT * FROM LegalActivity WHERE UlaChoice = @UlaChoice OPTION (Optimize FOR(@UlaChoice = ‘YP101′)) 2) You have the following query: SELECT * FROM CurrentProducts WHERE ShortName = ‘Yoga Trip’ You have a nonclustered index on the ShortName field and the query runs an efficient index seek. You change your query to use a variable for ShortName and now you are using a slow index scan. What query hint can you use to get the same execution time as before? WITH LOCK FAST OPTIMIZE FOR MAXDOP READONLY Now make sure that you write down all the answers on the piece of paper. Watch following video and read earlier article over here. If you want to change the answer you still have chance. Solution 1) 3 2) 4 Now compare let us check the answers and compare your answers to following answers. I am very confident you will get them correct. Available at USA: Amazon India: Flipkart | IndiaPlaza Volume: 1, 2, 3, 4, 5 Please leave your feedback in the comment area for the quiz and video. Did you know all the answers of the quiz?

He studied for Java certification, and he noted that getting his certification was a game changer because it helped him started to learn the nuances of the Java language. He has held other development positions, "You may have noticed that you don't get as much junk mail from Citibank as you used to - that is thanks to one of my projects!" he told us. Grazi joined Credit Suisse in 2005 and is currently Vice President on the central architecture team. Grazi is proud of his open source project, Java Concurrent Animated, a series of animations that visualize the functionality of the components in the java.util.concurrent library. "It has afforded me the opportunity to speak around the globe" and because of it, has discovered that he really enjoys doing public presentations. He is a fine addition to the Java Champions program. The Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Nominees are named and selected through a peer review process. Java Champions get the opportunity to provide feedback, ideas, and direction that will help Oracle grow the Java Platform.

• Making the WPeFfort

  - by Laila

  Microsoft Visual Studio 2010 will be launched on April 12th. The basic layout looks pretty much as it did, so it is not immediately obvious on first inspection that it was completely rewritten in the Windows Presentation Foundation (WPF). The current VS 2008 codebase had reached the end of its life; It was getting slow to initialize and sluggish to run, and was never going to allow for multi-monitor support or easier extensibility. It can't have been an easy decision to rewrite Visual Studio, but the gamble seems to have paid off. Although certain bugs in the betas caused some anxiety about performance, these seem to have been fixed, and the new Visual Studio is definitely faster. In rewriting the codebase, it has been possible to make obvious improvements, such as being able to run different windows on different monitors, and you only being presented with the Toolbox controls and References that are appropriate to your target .NET version. There is also an IntelliTrace debugger, and Intellisense has been improved by virtue of separating a 'Suggestion Mode' and 'Completion Mode' (with its 'Generate From.' 'Highlight References.', and 'Navigate to...' features). At the same time, there has been quite a clearout; Certain features that had been tucked away in the previous versions, such as Brief or Emacs emulation support, have been dropped. (Yes, they were being used!) There are a lot of features that didn't require the rewrite, but are welcome. It is now easier to develop WPF applications (e.g. drag-and-drop Databinding), and there is support for Azure. There are more, and better templates and the design tools are greatly improved (e.g. Expression Web, Expression Blend, WPF Sketchflow, Silverlight designer, Document Map Margin and Inline Call Hierarchy). Sharepoint is better supported, and Office apps will benefit from C#'s support of optional and named arguments, and allowing several Office Solutions within a Deployment package. Most importantly, it is a vote of confidence in the WPF. VS 2010 is the essential missing component that has been impeding the faster adoption of WPF. The fact that it is actually now written in WPF should now reassure the doubters, and convince more developers to make the move from WinForms to WPF. In using WPF, the developers of Visual Studio have had the clout to fix some issues which have been bothering WPF developers for some time (such as blurred text). Do you see a brighter future as a result of transferring from WinForms to WPF? I'd love to know what you think. Cheers, Laila

• JavaScript in different browsers

  - by PointsToShare

  Adventures with JavaScript rendered in IE 8, Chrome 15, and Firefox 8.0 I have written a little monogram about the advantages of Math and wrote a few JavaScript applications to demonstrate them. I was a bit careless and used elements on the page in my JavaScript without using any of the GetElementsByXXXX methods to identify them.  Say I had a text box named tbSeqNum into which I entered a number to be used in a computation. In my code I simply referred to its value by using it directly. Like here: Function Blah() {                 return tbSeqNum.value; } This ran fine in IE8. In IE, the elements are available as global variables. This is not the case in either Firefox or Chrome. In there one has to create the variable and only then use it. Assuming I also used tbSeqNum as the element’s ID, this works: Function Blah() {                 return GetElementById(“tbSeqNum”).value; } Naturally this corrected function also works in IE, so be warned. Also, coming from windows programming (I am long in the tooth and programmed long before the internet), I have a habit of putting an “Exit” button on my pages and setting their onclick to: onclick=”window.close()”. Again, this works fine in IE. In Firefox and chrome, it does not! There you can only close a window that you opened in the code. A window that was opened by navigation to a URL will not close.  Before I deployed mu code to my website, I painfully removed all my Exit buttons. But my greatest surprise came when I tested my pages in the various browsers. In my code I do a comparison on the performance of two algorithms used to solve the same problem. One is brute force, the other uses a mathematical formula. The compare functions runs each many times and displays the time it took for each and also the ratio. Chrome runs JavaScript between 5 and 10 times faster than Firefox and between 50 and 100 times faster that IE. Wow!!! This difference is especially remarkable when the code uses iteration. I suspect that the JS engines in Chrome and Firefox simply cache the result of a function and if it is called again with the same parameters, it returns the cached result. To see it in action play run the “How Many Squares” page in www.mgsltns.com/games.htm The host is running on Unix, so the link is case sensitive. Last Note: IE9 runs JS a bit faster, but still lags behind almost as badly. That’s All Folks!

• debootstrap or virt-install Ubuntu Server Maverick fails

  - by poelinca

  Oki so running any kind of variation of debootsrap i get the following error I: Extracting zlib1g... W: Failure trying to run: chroot /lxc/iso/dodo mount -t proc proc /proc debootstrap.log : mount: permission denied if i manualy chroot into the directory then i get promted with: id: cannot find name for group ID 0 I have no name!@...# i tryed addgroup but it's not installed , apt-get/aptitude : command not found , so i can't do anything with it . I've tryed ubuntu-vm-builder but since it's calling debootstrap i get the same error . Played with it for a few days and then i stoped and gaved virt-install a try , everithing works till i get to the console to finish the install witch shows only : Escape character is ^] and nothing more , no matter what i type . So basicly what i'm trying to do is build a usable chroot system so i can use it with lxc or libvirt . What are my options to get containers/virtualisation up and running ? I've read somewhere that i can use openvz templates with lxc or libvirt ? but how ? Let me know if you need aditional info ( p.s. doing all this on a dedicated server so i can't access it by hand , only ssh , plus on my local pc running ubuntu desktop maverick everithing works ) . EDIT Getting closer , i managed to understand how to use an openvz template with lxc , now the problem comes with the network bridge lxc-start: invalid interface name: br0 # Use same bridge device used in your controlling host setup lxc-start: failed to process 'lxc.network.link = br0 # Use same bridge device used in your controlling host setup ' lxc-start: failed to read configuration file i followed the exact steps to create a bridge and lxc conf looks like: lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 # Use same bridge device used in your controlling host setup lxc.network.hwaddr = {a1:b2:c3:d4:e5:f6} # As appropiate (line only needed if you wish to dhcp later) lxc.network.ipv4 = {10.0.0.100} # (Use 0.0.0.0 if you wish to dhcp later) lxc.network.name = eth0 # could likely be whatever you want Since it's not working i know smth is wrong so could somebody guyde me ? EDIT , looks like the base install was using an custom kernel ( bzImage-2.6.34.6-xxxx-grs-ipv6-65 ) for witch you i didn't found the headers , i did a update-grub after i installed a new kernel , edited menu.lst and no it's using 2.6.35-23-server and now debootstrap is working just fine same as ubuntu-vm-builder .

• DHCP server with multiple interfaces on ubuntu, destroys default gateway

  - by Henrik Alstad

  I use Ubuntu, and I have many interfaces. eth0, which is my internet connection, and it gets its info from a DHCP-server totally outisde of my control. I then have eth1,eth2,eth3 and eth4 which I have created a DHCP-server for.(ISC DHCP-Server) It seems to work, and I even get an IP-address from the foreign DHCP-server on the internet facing interface. However, for some reason it seems my gateway for eth0 became screwed after I installed my local DHCP-server for eth1-eth4. (I think so because I got an IP for eth0, and I can ping other stuff on the local network, but I cannot get access to the internet). My eth0-specific info in /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 10.0.1.1 netmask 255.255.255.0 network 10.0.1.0 broadcast 10.0.1.255 gateway 10.0.1.1 mtu 8192 auto eth2 iface eth2 inet static address 10.0.2.1 netmask 255.255.255.0 network 10.0.2.0 broadcast 10.0.2.255 gateway 10.0.2.1 mtu 8192 My /etc/default/isc-dhcp-server: INTERFACES="eth1 eth2 eth3 eth4" So why does my local DHCP-server fuck up the gateway for eth0, when I tell it not to listen to eth0? Anyone see the problem or what I can do to fix it? The problem seems indeed to be the gateways. "netstat -nr" gives: 0.0.0.0 --- 10.X.X.X ---- 0.0.0.0 --- UG 0 0 0 eth3 It should have been 0.0.0.0 129.2XX.X.X 0.0.0.0 UG 0 0 0 eth0 So for some reason, my local DHCP-server overrides the gateway I get from the network DHCP. Edit: dhcp.conf looks like this(I included info only for eth1 subnet): ddns-update-style none; not authoritative; subnet 10.0.1.0 netmask 255.255.255.0 { interface eth1; option domain-name "example.org"; option domain-name-servers ns1.example.org, ns2.example.org; default-lease-time 600; max-lease-time 7200; range 10.0.1.10 10.0.1.100; host camera1_1 { hardware ethernet 00:30:53:11:24:6E; fixed-address 10.0.1.10; } host camera2_1 { hardware ethernet 00:30:53:10:16:70; fixed-address 10.0.1.11; } } Also, it seems that the gateway is correctly set if I run "/etc/init.d/networking restart" in a terminal, but that's not helpful for me, I need the correct gateway to be set during startup, and i'd rather find the source of the problem

• Bluetooth Dial-Up Networking using Blueman

  - by leemes

  I want to configure a dial up network connection via bluetooth to my phone in order to access the internet. I use Lubuntu 12.04 (Ubuntu with LXDE) which has the Network Manager Applet and Blueman applet installed. I guess these are the same tools than on an Ubuntu installation, hence I ask my question on this site. My phone is a Sony Ericsson W810i, my laptop is a Lenovo S10-2, my mobile phone provider is o2 Germany. I scanned for my mobile phone using the Blueman applet. I connected the dial-up network via the context menu - Serial Ports - Dial-up Networking. A notification bubble says that the connection is available on the interface named ppp0. ipconfig is telling something different: There is no ppp0 or something similar. I only see my eth0 (wired ethernet), eth1 (wifi) and lo interfaces. Of course, I can't ping google.com as the interface really seems to be not present at all. When the dial-up network is being connected, my mobile phone says that it connects to the internet. Afterwards, I see the active connection on the phone's screen. When successfully connecting with the phone using another computer, it behaves exactly the same, so I guess that the phone isn't the problem. I don't know if I configured the Dial-Up correctly. I use the phone number *99# which is very common on most mobile ISPs. I use the APN which my ISP is telling me to use. (I can't find the number on their support page, so I just use the default value *99#.) My mobile ISP is o2 Germany. There are How-Tos out there which use the Network Manager Applet to setup a bluetooth dial-up connection, but I can't see any bluetooth devices in the context menu as on the screenshots in those How-Tos. Do you have any suggestions what might be wrong / what I should try? EDIT: When choosing "Network Access Point" in the device's context menu instead of Serial Ports - Dial-Up Networking, an interface bnep0 appears. However, neither an IPv4 address is assigned for that interface (but IPv6), nor the phone connects to the internet. Am I missing something? Can I connect to the internet after setting up this network connection?

• National Give Camp Weekend - January 14-16, 2011

  - by MOSSLover

  What is a Give Camp?  I get asked this question constantly in the SharePoint Community.  About 3 years ago there was an event called "We Are Microsoft" in Dallas, TX.  A lady named, Toi Wright, gathered up a bunch of charities and gathered up a bunch of IT Professionals in the community.  They met for an entire weekend devising better ways to help these charities with 3 days projects.  None of these charities had in house IT staff or they were lacking.  The time these projects would save would help out other people in the long run.  The first give camp was really popular that a couple guys from Kansas City decided to come up with a give camp in the Kansas City regiona.  The event was called Coders 4 Charity.  I read Jeff Julian's post on the "We Are Microsoft" event that it inspired me to get involved.  i showed up to this event and we were split into teams.  On that team I met a couple really awsome guys: Blake Theiss, Lee Brandt, Tim Wright, and Joe Loux.  We created a SharePoint site for a boyscout troup.  It was my first exposure to Silverlight 1.1.  I had so much fun that I attended the event the next year and the St. Louis Coders 4 Charity.  Last year in 2010 when I moved i searched high and low.  Sure enough they had an event in Philadelphia.  I helped out with two SharePoint Projects for a team of firefighters and another charity.  This year there are a series of give camps around the U.S.  They have consolidated most of the give camps.  The first ever New York City Give Camp is on National Give Camp Day.  If you guys are interested I see there is a give camp in Philadelphia, St. Louis, Northwest Arkansas, Seattle, Atlanta, Houston, and more...Here is a link to the site I would definitely encourage you to get involved: http://givecamp.org/national-givecamp/.  Also, if you feel like it's only developer focused that's entirely wrong.  They need DBAs, Project Leads, Architects, and many other roles fulfilled aside from development.  It is a great experience to meet good people and help out a charity doing what we all love to do.  I strongle encourage getting involved in a give camp.  if you are coming to the NYC Give Camp I would love to meet you.  i will be there on Saturday somewhere in the morning until around dinner time.

• How (recipe) to build only one kernel module?

  - by Pro Backup

  I have a bug in a Linux kernel module that causes the stock Ubuntu 14.04 kernel to oops (crash). That is why I want to edit/patch the source of only that single kernel module to add some extra debug output. The kernel module in question is mvsas and not necessary to boot. For that reason I don't see any need to update any initrd images. I have read a lot of information (as shown below) and find the setup and build process confusion. I need two recipes: to setup/configure the build environment once steps to do after editing any source file of this kernel module (.c and .h) and converting that edit into a new kernel module (.ko) The sources that have been used are: build one kernel module - Google search http://www.linuxquestions.org/questions/linux-kernel-70/rebuilding-a-single-kernel-module-595116/ http://stackoverflow.com/questions/8744087/how-to-recompile-just-a-single-kernel-module http://www.pixelbeat.org/docs/rebuild_kernel_module.html How do I build a single in-tree kernel module? http://ubuntuforums.org/showthread.php?t=1153067 http://ubuntuforums.org/showthread.php?t=2112166 http://ubuntuforums.org/showthread.php?t=1115593 build one kernel module ubuntu - Google search 'make +single +kernel +module' - Ask Ubuntu 'make +kernel +module' - Ask Ubuntu My makefile results in: No rule to make target `arch/x86/tools/relocs.c', needed '"Invalid module format"' - Ask Ubuntu Driver installation: compiling source code for newer kernel Modprobe: 'Invalid nodule format', yet works after insmod "Symbol version dump" "is missing" - Google search http://stackoverflow.com/questions/9425523/should-i-care-that-the-symbol-version-dump-is-missing-how-do-i-get-one Where can I find the corresponding Module.symvers and .config files for 12.04.3 i386 server?

• permanently load module

  - by Radu

  I have a Compaq Presario CQ-61 320SQ, I am using Ubuntu 10.04 because after update to 10.10 my mouse and touchpad won't work, network won't work, sound won't work ... (I managed to fix most of them after almost a month of googling, but not all, my 2 Desktops have no problem with 10.10) so I decided to switch back to 10.04, where I have a problem: My broadband speed is very low beacause of the kernel module r8169, I downloaded the good module r8101 and every time the computer boots have a rc.local entry to fix this. Question: Can I load the modul permanently from a specific location. I heard about /etc/modules but there I need the module name, but I have to load it from a specific path (where is the default path for that) Thank you. So I studied the script: It creates the file r8101.ko in /lib/modules/uname -r/kernel/drivers/net so I think as long as nobody will delete that file, and I don't update the kernel, maybe adding r8108 to /etc/modules will work, and add r8169 to blacklist ... I will give it a try. EDIT2: So I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf It still uses the old module, lsmod prints: radu@adu:~$ lsmod | grep r8 r8101 67626 0 r8169 34108 0 mii 4381 1 r8169 EDIT: the module is loaded using this script that came with it: #!/bin/sh # invoke insmod with all arguments we got # and use a pathname, as insmod doesn't look in . by default TARGET_PATH=/lib/modules/`uname -r`/kernel/drivers/net echo echo "Check old driver and unload it." check=`lsmod | grep r8169` if [ "$check" != "" ]; then echo "rmmod r8169" /sbin/rmmod r8169 fi check=`lsmod | grep r8101` if [ "$check" != "" ]; then echo "rmmod r8101" /sbin/rmmod r8101 fi echo "Build the module and install" echo "-------------------------------" >> log.txt date 1>>log.txt make all 1>>log.txt || exit 1 module=`ls src/*.ko` module=${module#src/} module=${module%.ko} if [ "$module" == "" ]; then echo "No driver exists!!!" exit 1 elif [ "$module" != "r8169" ]; then if test -e $TARGET_PATH/r8169.ko ; then echo "Backup r8169.ko" if test -e $TARGET_PATH/r8169.bak ; then i=0 while test -e $TARGET_PATH/r8169.bak$i do i=$(($i+1)) done echo "rename r8169.ko to r8169.bak$i" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i else echo "rename r8169.ko to r8169.bak" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak fi fi fi echo "Depending module.

• Naming Convention for Dedicated Thread Locking objects

  - by Chris Sinclair

  A relatively minor question, but I haven't been able to find official documentation or even blog opinion/discussions on it. Simply put: when I have a private object whose sole purpose is to serve for private lock, what do I name that object? class MyClass { private object LockingObject = new object(); void DoSomething() { lock(LockingObject) { //do something } } } What should we name LockingObject here? Also consider not just the name of the variable but how it looks in-code when locking. I've seen various examples, but seemingly no solid go-to advice: Plenty of usages of SyncRoot (and variations such as _syncRoot). Code Sample: lock(SyncRoot), lock(_syncRoot) This appears to be influenced by VB's equivalent SyncLock statement, the SyncRoot property that exists on some of the ICollection classes and part of some kind of SyncRoot design pattern (which arguably is a bad idea) Being in a C# context, not sure if I'd want to have a VBish naming. Even worse, in VB naming the variable the same as the keyword. Not sure if this would be a source of confusion or not. thisLock and lockThis from the MSDN articles: C# lock Statement, VB SyncLock Statement Code Sample: lock(thisLock), lock(lockThis) Not sure if these were named minimally purely for the example or not Kind of weird if we're using this within a static class/method. Several usages of PadLock (of varying casing) Code Sample: lock(PadLock), lock(padlock) Not bad, but my only beef is it unsurprisingly invokes the image of a physical "padlock" which I tend to not associate with the abstract threading concept. Naming the lock based on what it's intending to lock Code Sample: lock(messagesLock), lock(DictionaryLock), lock(commandQueueLock) In the VB SyncRoot MSDN page example, it has a simpleMessageList example with a private messagesLock object I don't think it's a good idea to name the lock against the type you're locking around ("DictionaryLock") as that's an implementation detail that may change. I prefer naming around the concept/object you're locking ("messagesLock" or "commandQueueLock") Interestingly, I very rarely see this naming convention for locking objects in code samples online or on StackOverflow. Question: What's your opinion generally about naming private locking objects? Recently, I've started naming them ThreadLock (so kinda like option 3), but I'm finding myself questioning that name. I'm frequently using this locking pattern (in the code sample provided above) throughout my applications so I thought it might make sense to get a more professional opinion/discussion about a solid naming convention for them. Thanks!

• Game of Phones

  - by Carlos Chang

  Game  of  Phones There’s an excellent DZone article titled: 2014 Guide to Mobile Development. It’s loaded with excellent information including some results from a mobile related survey to more than 1000 IT professionals. Without giving away too much, these highlights should convince you to read the entire article.  Web and Hybrid apps are gaining tons of traction particularly in the enterprise. If you want to better understand the differences between Web, Native and Hybrid, this article has you covered. Enterprise developers are increasingly more interested in cross platform tools. Makes sense right?  I mean, unless you have infinite resources (e.g. Facebook) and can afford to write native apps to every platform, finding something that can meet your needs for iOS and Android makes sense.  And toss in the possibility of Windows Phone …and oh, just to be current, the addition of Apple’s new mobile language, Swift, to add to Objective C.. and oh boy.  Why not check out cross platform tools? BTW, don’t  forget testing on each platform, and maintenance and the next versions of the app. It’s not one and done. If you’re successful, you’re never done. Various mobile vendors are represented and many provide some great information.  Oracle's own Suhas Uliyar, VP of Mobile Strategy, represented with some great insights into the challenges of mobile back end integration (SOA, mBaaS, etc.) and moving from "mobile first" to a mobile plus world. BTW, Suhas was recently named Top 100 Wireless Technology Experts for 2014 by Today's Wireless World magazine.  And if your not yet convinced, DZone did a very nice job with their mobile infographic stylized after the insanely popular series, Game of Thrones.  Even though there were no dragons illustrated, worth the price of admission just for that.   Check it out here.

• Beware of const members

  - by nmarun

  I happened to learn a new thing about const today and how one needs to be careful with its usage. Let’s say I have a third-party assembly ‘ConstVsReadonlyLib’ with a class named ConstSideEffect.cs: 1: public class ConstSideEffect 2: { 3: public static readonly int StartValue = 10; 4: public const int EndValue = 20; 5: } In my project, I reference the above assembly as follows: 1: static void Main(string[] args) 2: { 3: for (int i = ConstSideEffect.StartValue; i < ConstSideEffect.EndValue; i++) 4: { 5: Console.WriteLine(i); 6: } 7: Console.ReadLine(); 8: } You’ll see values 10 through 19 as expected. Now, let’s say I receive a new version of the ConstVsReadonlyLib. 1: public class ConstSideEffect 2: { 3: public static readonly int StartValue = 5; 4: public const int EndValue = 30; 5: } If I just drop this new assembly in the bin folder and run the application, without rebuilding my console application, my thinking was that the output would be from 5 to 29. Of course I was wrong… if not you’d not be reading this blog. The actual output is from 5 through 19. The reason is due to the behavior of const and readonly members. To begin with, const is the compile-time constant and readonly is a runtime constant. Next, when you compile the code, a compile-time constant member is replaced with the value of the constant in the code. But, the IL generated when you reference a read-only constant, references the readonly variable, not its value. So, the IL version of the Main method, after compilation actually looks something like: 1: static void Main(string[] args) 2: { 3: for (int i = ConstSideEffect.StartValue; i < 20; i++) 4: { 5: Console.WriteLine(i); 6: } 7: Console.ReadLine(); 8: } I’m no expert with this IL thingi, but when I look at the disassembled code of the exe file (using IL Disassembler), I see the following: I see our readonly member still being referenced by the variable name (ConstVsReadonlyLib.ConstSideEffect::StartValue) in line 0001. Then there’s the Console.WriteLine in line 000b and finally, see the value of 20 in line 0017. This, I’m pretty sure is our const member being replaced by its value which marks the upper bound of the ‘for’ loop. Now you know why the output was from 5 through 19. This definitely is a side-effect of having const members and one needs to be aware of it. While we’re here, I’d like to add a few other points about const and readonly members: const is slightly faster, but is less flexible readonly cannot be declared within a method scope const can be used only on primitive types (numbers and strings) Just wanted to share this before going to bed!
