• SSIS Tips & Tricks (Presentation)

  This has been a rather well used presentation title but it does allow a certain degree of flexibility, and we covered a good range of topics in my session at the UK SQL Server User Group in Cambridge last night. Thanks to all who attended. Here is the rather limited slide deck and the all important demo packages for download as promised. For reference, high level topics covered were BIDS Helper Inserts and Updates Transactions Script Debugging Data Flow Checkpoints I’ll update the post with a link to the Live Meeting recording when I get it.

• The new Google Analytics - what new useful features have you found?

  - by Rob

  If you don't know already a new version of Google Analytics has just come out. On first initial views it doesn't seem like much of an improvement on the previous version. There's lot's linking to Google's social stats but I'm yet to see the value of that. Also it doesn't seem to make the best use of the important data, it's tending to push referral sites, keywords to the back and bring the less important data to the front. Is that a sign of things to come??? One feature I did find interesting was the visitors flow as it shows the visitors path through your site. What new features have you found useful/interesting?

• Can I force a workstation to use a specific domain controller?

  - by Chad

  I'm on a domain that I can't control the domain controllers on, but I can control my systems. All the domain controllers are part of one site, and that cannot change. However, one of the domain controllers is not working correctly and the admins in charge of it are taking forever to resolve the issue. There are 6 total domain controllers... for some reason my workstations/servers are still attempting to use the bad one to authenticate my users. Is there a way to force a workstation to use specific domain controllers? or, better yet, force it to NOT use the bad one? Thanks in advance!

• Import Java Trusted Certificate to JRE

  - by Zalastax

  I need to install a certificate from a Java app to a lot of people. I want to use a one click program or batch file to import it as a Trusted Certificate(in Control Panel-Security-Certificate). Then they won't need to press always allow first time they use the application. I have extracted the needed certificate as both a .csr and as a .cer (the .csr via Control Panel and the .cer via keytool). Now I need to get one of them back without any clicking in menus. I don't really understand the documentation of importing .cer with keytool and would like an example. Or are there an easier way than using keytool?

• How to understand Linux kernel source code for a beginner?

  - by user16867

  I am a student interested in working on Memory Management, particularly the page replacement component of the linux kernel. What are the different guides that can help me to begin understanding the kernel source? I have tried to read the book Understanding the Linux Virutal Memory Manager by Mel Gorman and Understanding the Linux Kernel by Cesati and Bovet, but they do not explain the flow of control through the code. They only end up explaining various data structures used and the work various functions perform. This makes the code more confusing. My project deals with tweaking the page replacement algorithm in a mainstream kernel and analyse its performance for a set of workloads. Is there a flavor of the linux kernel that would be easier to understand(if not the linux-2.6.xx kernel)?

• Good practices in screen states management?

  - by DevilWithin

  I wonder what are the best ways to organize different screens in a game? I am thinking of it like this: Inheriting a base State class, and overriding update and render methods, to handle the current screen. Then, under certain events a StateManager is able to activate another Screen State, and the game screen changes as only the current State is rendered. On the activation of a new screen, effects like fading could be added, and also the same goes for its deactivation. This way a flow of screen could be made. By saying when A ends, B starts, allowing for complex animations etc. Toughts?

• How to design console application with good seperation of UI from Logic

  - by JavaSa

  Is it considered an overkill for console application to be design like MVC , MVP or N tier architecture? If not which is more common and if you can link me to simple example of it. I want to implement a tic tac toe game in console application. I have a solution which hold two projects: TicTacToeBusinessLogic (Class library project) and TicTacToeConsoleApplication (Console application project) to represent the view logic. In the TicTacToeConsoleApplication I've Program.cs class which holds the main entry point (public static void Main). Now I face a problem. I want the game to handle its own game flow so I can: Create new GameManager class (from BL) but this causing the view to directly know the BL part. So I'm a little confused how to write it in an acceptable way. Should I use delegates? Please show me a simple example.

• Ubuntu 12.04 desktop, VNC viewer not refreshing screen

  - by user73279

  I've had this issues across multiple machines and multiple versions of Ubuntu desktop (all 10.04 or later). Usually it happens with an old laptop I've put Ubuntu on but now it's happening on my primary dev machine (a quad-core PC recently upgraded to Ubuntu 12.04 desktop). The problem is this - I can connect to the machine and login with the password, the initial screen looks fine but never refreshes. I can see the monitor for the machine across the room and can see the mouse move and the menus pop up but the image of the screen on the PC in front me running the VNC viewer never updates. So the mouse and keyboard commands are working. Ubuntu 12.04 Desktop Ultra VNC Viewer (also seen with RealVNC's free VNC viewer) Desktop Sharing Static IP on eth0; Dynamic ID on eth1 I think it is an Ubuntu config issue because this PC used to work just fine with 9.04, 10.04, and 11.10 (over the past couple of years). I've also had a couple of laptops that used to have this issue with older Ubuntu's but don't with 12.04. Additional info: The Win7 PC I'm trying to use to control the Ubuntu PC is connected via 2 DLink 8-port gigabit routers. The Ubuntu laptop I usually control via VNC is typically only connected to the network via wireless. The screen refresh is choppy but usable. I've repeated the issue on a Win7 laptop which was connected via ethernet and wireless.

• Is acousting fingerprinting too broad for one audio file only?

  - by IBG

  So we were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acousting fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

• SSIS Denali CTP1 Source Assistant

  - by andyleonard

  I like the new Data Flow Source Assistant in SSIS Denali. The default view is shown above, with the "Show installed only" checkbox checked. When not checked, the list of Source types changes: In previous versions of SSIS, I rarely created connections in the Connection Managers pane - I usually hit a New button in either a Source or Destination Adapter, or in a task. It was just easier letting the task or adapter pick the proper Connection Manager editor. This is handy and a time-saver. :{>...(read more)

• Nginx + PHP-FPM ignores no-cache headers

  - by Eric Winchell

  I'm using the following header on a php page. // Prevent page caching. header('Expires: Tue, 20 Oct 1981 05:00:00 GMT'); header('Cache-Control: no-store, no-cache, must-revalidate'); header('Cache-Control: post-check=0, pre-check=0', FALSE); header('Pragma: no-cache'); I'm also using a rand=999999999 (with a real random number) in the URLs. But pages are still being cached. Reload works, but first load is cached. Anyone know where I can change this?

• SSIS 2008 Configuration Settings Handling Logic for Variables Visualized

  - by Compudicted

  There are many articles discussing the specifics of how the configuration settings are applied including the differences between SSIS 2005 and 2008 version implementations, however this topic keeps resurfacing on MSDN’s SSIS Forum. I thought it could be useful to cover the logic aspect visually. Below is a diagram explaining the basic flow of a variable setting for a case when no parent package is involved.   As you can see the run time stage ignores any command line flags for variables already set in the config file, I realize this is not stressed enough in many publications. Besides, another interesting fact is that the command line dtexec tool is case sensitive for the portion following the package keyword, I mean if you specify your flag to set a new value for a variable like dtexec /f Package.dtsx -set \package.variables[varPkgMyDate].value;02/01/2011 (notice the lover case v in .value) You will get errors. By capitalizing the keyword the package runs successfully.

• What issues ensue from having multiple versions of Office installed?

  - by Michael Sorens

  My ultimate question is embodied in the title but I thought it might be helpful to others if I detail what instigated my inquiry and my examination of the problem. To me, the first rule of software updates is Primum non nocere -- first, do no harm. So with my Windows 7 system containing both Office 2003 and Office 2010 I blithely proceeded to install this month's updates from Microsoft, containing updates for both versions of Office. While Microsoft officially does not recommend running multiple versions (see, for example, Running Multiple Versions of Microsoft Excel it is possible; I have had two versions installed for a year or more and have never run into an issue before. One thing that is always mentioned is installation order, i.e., the one you want to open files by default should be installed last. I wanted 2010 as my default so I had indeed installed 2003 first then, years later, 2010. So with this round of Windows updates, either it installed patches to 2010 before 2003, knocking out the file association, or the 2003 patch was more comprehensive, in the sense of touching the file association while the 2010 did not. In any case, after updates, double-clicking a .xls file opened 2003 rather than 2010. Web search indicated either: Use the file associations control panel to re-associate .xls files with the correct version of excel. I looked at this first, but it showed what seemed to be an unversioned "Excel" associated with .xls files so I did not check further. (This turned out to be an error on my part; more later.) Re-install versions in the desired order; I find this unreasonable. Run the repair option of the Office installer on the desired version; still seems more work than one should need. Run excel from the command line with "/regserver" on the one to be the default and "/unregserver" on the other. Good idea, but further search indicated that neither 2007 nor 2010 support "/regserver" contrary to some posts (e.g. Default Program With Multiple Versions Installed). Since this was a Windows Update issue and Microsoft provides free support for such, I inquired there as well, but succeeded only in getting the suggestion to uninstall all other versions, period; not acceptable to me. What worked for me was going back to the file associations control panel and manually selected the Office 2010 version of Excel. While it appeared no different in the control panel, it did fix the double-click issue. So if all it takes is this simple fix after an update, I can live with that. What I am wondering is: Has anyone seen any other problems related to having multiple versions of Office installed?

• Notebook with NVIDIA Optimus not switching video card in games

  - by user140739

  I have a Samsung RC720 notebook with Intel Integrated Graphics and NVIDIA GeForce GT 520M. As you can see it has two video adapters and Optimus is supposed to switch between them. But when I choose dedicated GPU in NVIDIA Control Panel and try to run, for example, GTA IV, it uses integrated graphics and I get very poor performance. I have already installed last NVIDIA and notebook drivers, chose high-performance in NVIDIA Control Panel, tried to execute with "Run with graphics processor..." context option and so on. Thanks for help.

• Is using Javascript/JQuery for layout and style bad practice?

  - by Renesis

  Many, but not all, HTML layout problems can be solved with CSS alone. For those that can't, JQuery (on document load) has become very popular.* As a result of its ease, many developers are quick to use JQuery or Javascript for layout and style — even without understanding whether or not the problem can be solved with CSS alone. This is illustrated by responses to questions like this one. Is this bad practice? What are the arguments for/against? Should someone who sees this in practice attempt to persuade those developers otherwise? If so, what are the best responses to arguments in favor of JQuery saying it's "so easy"? * Example: Layouts that wish to use vertical layout flow of some kind often run into dead ends with CSS alone — this would include layouts similar to Pinterest, though I'm not sure that's actually impossible with CSS.

• Correct architecture for running and stopping complex tasks in the background

  - by Phonon

  I'm having trouble working out the correct architecture for the following task. I have a GUI in Windows Forms that contains a ListBox, listing certain architectural layouts. One an item in this list is selected, a custom Control displays an interactive visualization of the selected layout. Drawing of this interactive diagram is a CPU-intensive task, and can take up to a second on my machine. The kind of functionality I'm trying to achieve is that if a user wants to quickly scroll through the layouts in the ListBox (say, holding down the down arrow key), I don't want my computer to sit there thinking about how to draw the layout before it allows the user to do anything else. The obvious answer is, of course, to run the layout calculations in a separate thread. But how do I make that thread return a whole control? How do I make sure I'm not running two layout calculations at once? I'm fairly new to this complex GUI business. So the real question is what is the right architecture to implement something like this? This seems like something people do all the time, but finding any suggestions on how to do it properly is really difficult.

• Nifty default controls prevent the rest of my game from rendering

  - by zergylord

  I've been trying to add a basic HUD to my 2D LWJGL game using nifty gui, and while I've been successful in rendering panels and static text on top of the game, using the built-in nifty controls (e.g. an editable text field) causes the rest of my game to not render. The strange part is that I don't even have to render the gui control, merely declaring it appears to cause this problem. I'm truly lost here, so even the vaguest glimmer of hope would be appreciated :-) Some code showing the basic layout of the problem: display setup: // load default styles nifty.loadStyleFile("nifty-default-styles.xml"); // load standard controls nifty.loadControlFile("nifty-default-controls.xml"); screen = new ScreenBuilder("start") {{ layer(new LayerBuilder("baseLayer") {{ childLayoutHorizontal(); //next line causes the problem control(new TextFieldBuilder("input","asdf") {{ width("200px"); }}); }}); }}.build(nifty); nifty.gotoScreen("start"); rendering glMatrixMode(GL_PROJECTION); glLoadIdentity(); GLU.gluOrtho2D(0f,WINDOW_DIMENSIONS[0],WINDOW_DIMENSIONS[1],0f); //I can remove the 2 nifty lines, and the game still won't render nifty.render(true); nifty.update(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); GLU.gluOrtho2D(0f,(float)VIEWPORT_DIMENSIONS[0],0f,(float)VIEWPORT_DIMENSIONS[1]); glTranslatef(translation[0],translation[1],0); for (Bubble bubble:bubbles){ bubble.draw(); } for (Wall wall:walls){ wall.draw(); } for(Missile missile:missiles){ missile.draw(); } for(Mob mob:mobs){ mob.draw(); } agent.draw();

• How do I replace a harddrive that is in a two-way mirror storage space on Windows 8?

  - by Jon

  I have a storage space in Windows 8 doing a two-way mirror on three harddrives. The sizes are 297GB, 189GB, and 70GB. I would like to replace the 70GB HD with a larger one. My thought was to remove that drive from the space via the Storage Space control panel, shutdown, replace HD with bigger drive, reboot, add new HD to the storage space. I can't find any options to remove a HD from a storage space in the control panel. Should I just shutdown and swap out the small drive or is there another process for safely replacing the old HD? (By the way, the old HD is still operational.)

• Any way I can correct DNS spoofing against our domain

  - by brandon

  This morning I found out that our domain and subdomains have been poisoned on the 4.2.2 and 4.2.2.1 DNS servers along with others I think, though I have not confirmed others yet. Using OpenDNS resolution works correctly. I have updated our local DNS servers and cleared their cache which has fixed things internally. The issue is that the domain is public facing and customers are having problems. We are the authoritative DNS server for the domain and all that is under our control. What I don't know how to do is fix the name servers out of our control. Is there something we can do on our end? At the moment the only workaround I can think of is to ask customers to change their DNS to OpenDNS which is not very practical. The other workaround would be to change our TLD, which is less practical.

• suggestions for lonewolf dev setup

  - by d33j

  I'm looking for some suggestions for a better development setup. Background: I'm a crusty old software engineer (mostly java of late) and I have around 50 - 100 incomplete java projects scattered everywhere, usb keys, HDDs, and spanning across 5 or 6 computers etc, which have been put on hold for a few years (ie: family). I have no version control at home. I've been using IntelliJ for around 10 years, so that's the only constant. I'm thinking of nominating one machine as a headless server to put all my projects on, maybe a ubuntu box, that way It won't matter which device I'm on, all my projects can be accessed (and I don't have to waste time actually looking for them). I don't need to access code over the net. These are my own 'happy place' projects so I only work on them when I'm at home, however I can see the benefit of the tasking app being online, that way if I think of something while on public transport lets say, I can add it then & there, but it's not a requirement. I can wait until I get home to create tasks. Summary: So I need some sort of version control so I can rollback mistakes, and some sort of simple tasking software where I can assign tasks for myself later on when I get time. I use Subversion, Sonar, Jira and Crucible at work but I think it's a little bit of an overkill for me though. What do you suggest?

• Sendmail Alias for Nonlocal Email Account

  - by Mark Roddy

  I admin a server which is running a number of web applications for a software dev team (source control, bug tracking, etc). The server has sendmail running solely as a transport to the departmental email server over which I have no control. We have someone who is still in the department but no longer on the dev team so I need to configure the transport agent to redirect all outgoing email (which would be coming from these applications) to the person that has taken their place. I added an entry in /etc/aliases like such: [email protected]: [email protected] But when I run /etc/init.d/sendmail newaliases I get the following error: /etc/mail/aliases: line 32: [email protected]... cannot alias non-local names So clearly I'm doing something I shouldn't. Is there a way to get aliases to work with non-local names or alternatively is their a way to accomplish my goal of redirecting outgoing mail for this user to another one? Technical Specs if the matter: Ubuntu 6.06 sendmail 8.13 (ubuntu provided package)

• Install a program from the network

  - by Gomibushi

  In Windows there is a place under the Control Panel called Get Programs and Install a program from the network (in Win 7 at least), possibly a slightly different name in Vista, but it was there too. The question is basically: How do you publish programs to that so users can go there and install? Bonus follow up: Is it a good way to deploy optional programs? (Compared to using GPO's.) In Windows 7 you can go to Control Panel, Programs, Programs and Features, and on the left hand menu: Install a program from the network.
