  • Simultaneously execute two queries on a shell script

    - by Alex
    I have a shell script in which I have to execute two queries (on different databases), spool their results to text files and finally call a c++ program that processes the information on those text files. Something like this: sqlplus user1/pw1@database1 @query1.sql sqlplus user2/pw2@database2 @query2.sql ./process_db_output Both queries take some time to execute. One of them can take up to 10 minutes, while the other one is usually faster. What I want to do is execute them simultaneously and when both are done, call the processing utility. Any suggestion on how to do so?

  • Best algorithm/practice when creating a search mechanism for your database?

    - by Alex Hope O'Connor
    I have been designing a database where it is very important to provide users with a good search mechanism. So I was wondering what some of the best practices are for using keywords to search over multiple database tables and return the relevent records? Some other things I am curious about: The users location, if they provide an address The speed of the algorithm Additional Information: I am using C# and LINQ-To-SQL.

  • I am so confused about desktop/viewport switching, all I want to do is bind keyboard shortcuts to switch desktops

    - by Alex
    I've installed a pre-made Ubuntu 10.04 image at work, and I can't seem to figure out how to get desktop switching to work. No shortcuts work, and all the help I can get from the Ubuntu forums is "CTRL-Alt-Left/Right should work." So lemme get this straight. Switching between desktops is deprecated, so we use viewports, which are managed by Compiz, which has one of the most absurd configuration managers out there. Lovely. Can anyone straighten this out for me, and anyone else who might stumble on this question?

  • removing an ssrs instance from a scale-out deployment

    - by Alex Bransky
    If you're like me you had at one time connected one of your Reporting Services instances to a report server database that was already in use by another instance.  This allows the instance to show up in the Scale-out Deployment section of the Reporting Services Configuration Manager.  My problem was that the server that got joined to the original server was no longer available as it had been repurposed, and when I clicked Remove Server to remove it from my scale-out it would fail because it couldn't contact the server.  After searching for a solution for quite some time I decided to look around in the report server database tables, and voila!  All I had to do was remove the old server from the Keys table.  I can't guarantee there won't be any side effects to this method, but it worked like a charm for me.

  • DX10 sprite and pixel shader

    - by Alex Farber
    I am using ID3DX10Sprite to draw 2D image on the screen. 3D scene contains only one textured sprite placed over the whole window area. Render method looks like this: m_pDevice-ClearRenderTargetView(...); m_pSprite-Begin(D3DX10_SPRITE_SORT_TEXTURE); m_pSprite-DrawSpritesImmediate(&m_SpriteDefinition, 1, 0, 0); m_pSprite-End(); Now I want to make some transformations with the sprite texture in a shader. Currently the program doesn't work with shader. How it is possible to add pixel shader to the program with this structure? Inside the shader, I need to set all colors equal to red, and multiply pixel values by some coefficient. Something like this: float4 TexturePixelShader(PixelInputType input) : SV_Target { float4 textureColor; textureColor = shaderTexture.Sample(SampleType, input.tex); textureColor.x = textureColor.x * coefficient; textureColor.y = textureColor.x; textureColor.z = textureColor.x; return textureColor; }

  • Webapps don't open correctly when using Chromium

    - by Alex
    I have just installed Ubuntu 12.10 completely fresh, the old version of Ubuntu was discarded or overwritten (or whatever you call it). I want to use the Ubuntu webapps with Chromium but I've had several problems. }The first problem is that Chromium won't ask me if I want to install a webapp if I go to a supported site (and I don't already have the webapp installed). The second problem is that when I install the webapp by visiting the site in Firefox, and then I try to open it in Chromium, Ubuntu will open a completely new Chromium icon and window in the Launcher, and the icon will be labeled "Untitled"; also there is no search bar in the new window, only the tab at the top. I've tried using several webapps with Firefox set as the default browser and they work as expected: once the webapp icon is clicked a Firefox window is opened on the Firefox launcher icon, and the window has 'new tab' button and search bar.

  • Hidden Gems: Accelerating Oracle Data Integrator with SOA, Groovy, SDK, and XML

    - by Alex Kotopoulis
    On the last day of Oracle OpenWorld, we had a final advanced session on getting the most out of Oracle Data Integrator through the use of various advanced techniques. The primary way to improve your ODI processes is to choose the optimal knowledge modules for your load and take advantage of the optimized tools of your database, such as OracleDataPump and similar mechanisms in other databases. Knowledge modules also allow you to customize tasks, allowing you to codify best practices that are consistently applied by all integration developers. ODI SDK is another very powerful means to automate and speed up your integration development process. This allows you to automate Life Cycle Management, code comparison, repetitive code generation and change of your integration projects. The SDK is easily accessible through Java or scripting languages such as Groovy and Jython. Finally, all Oracle Data Integration products provide services that can be integrated into a larger Service Oriented Architecture. This moved data integration from an isolated environment into an agile part of a larger business process environment. All Oracle data integration products can play a part in thisracle GoldenGate can integrate into business event streams by processing JMS queues or publishing new events based on database transactions. Oracle GoldenGate can integrate into business event streams by processing JMS queues or publishing new events based on database transactions. Oracle Data Integrator allows full control of its runtime sessions through web services, so that integration jobs can become part of business processes. Oracle Data Service Integrator provides a data virtualization layer over your distributed sources, allowing unified reading and updating for heterogeneous data without replicating and moving data.

  • Accidentally deleted /opt/local/bin without backup. Any help?

    - by Aaron
    Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

  • Large enterprise application - clients wish to use duplicate e-mails addresses?

    - by Alex Key
    I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: [email protected] James Jeffery: [email protected] Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

  • Intel GMA 4500MHD flickering in opengl

    - by Aaron
    I have an application that uses OpenGL for its display. When this application is run on a laptop with an Intel GMA 4500MHD on Windows XP the OpenGL content appears to flicker/shudder between 2 frames. I have experienced the exact same problem when running this application on nVidia Quadro FX hardware, however with nVidia the problem can be corrected by disabling the "Unified Back Buffer" (UBB) feature in the driver. Does anybody know how I can disable the corresponding feature in the Intel driver?

  • Where is Sphinx located after I install it?

    - by Alex
    I have to install Sphinx on my Ubuntu 11.10 for it to work on a ruby app. I managed to install it through synaptics, however when I run my sphinx (rake ts:rebuild) I get an error message saying: Sphinx cannot be found on your system. You may need to configure the following settings in your config/sphinx.yml file: * bin_path * searchd_binary_name * indexer_binary_name I guess I just need to edit the sphinx.yml file with the right info but hey, I can't seem to find out where sphinx is. Any help?

  • PC reboots spontaenously: debugging tips

    - by aaron
    I swapped my core 2 duo for a quad core recently, and generally things run fine, but every now and then my computer just restarts. I don't even get a blue screen (Vista 32). Core temp isn't a problem. My thinking is that my power supply is inadequate, but I haven't been able to test that (one idea was to under clock the cpu to see if that helped, but going up in speed was the only simple thing to do in the BIOS) Two cases where I semi-consistanly get problems: - Borderlands windowed after some period of time (and some other games, but Borderlands does it pretty regularly) - watching a video (e.g. quicktime/vlc) and having another video running Another thought is non-cpu heat? Maybe the graphics card? Any thoughts on how to track this down appreciated. Thanks!

  • C# 5: At last, async without the pain

    - by Alex.Davies
    For me, the best feature in Visual Studio 11 is the async and await keywords that come with C# 5. I am a big fan of asynchronous programming: it frees up resources, in particular the thread that a piece of code needs to run in. That lets that thread run something else, while waiting for your long-running operation to complete. That's really important if that thread is the UI thread, or if it's holding a lock because it accesses some data structure. Before C# 5, I think I was about the only person in the world who really cared about asynchronous programming. The trouble was that you had to go to extreme lengths to make code asynchronous. I would forever be writing methods that, instead of returning a value, accepted an extra argument that is a "continuation". Then, when calling the method, I'd have to pass a lambda in to it, which contained all the stuff that needed to happen after the method finished. Here is a real snippet of code that is in .NET Demon: m_BuildControl.FilterEnabledForBuilding(     projects,     enabledProjects = m_OutOfDateProjectFinder.FilterNeedsBuilding(         enabledProjects,         newDirtyProjects =         {             // Mark any currently broken projects as dirty             newDirtyProjects.UnionWith(m_BrokenProjects);             // Copy what we found into the set of dirty things             m_DirtyProjects = newDirtyProjects;             RunSomeBuilds();         })); It's just obtuse. Who puts a lambda inside a lambda like that? Well, me obviously. But surely enabledProjects should just be the return value of FilterEnabledForBuilding? And newDirtyProjects should just be the return value of FilterNeedsBuilding? C# 5 async/await lets you write asynchronous code without it looking so stupid. Here's what I plan to change that code to, once we upgrade to VS 11: var enabledProjects = await m_BuildControl.FilterEnabledForBuilding(projects); var newDirtyProjects = await m_OutOfDateProjectFinder.FilterNeedsBuilding(enabledProjects); // Mark any currently broken projects as dirty newDirtyProjects.UnionWith(m_BrokenProjects); // Copy what we found into the set of dirty things m_DirtyProjects = newDirtyProjects; RunSomeBuilds(); Much easier to read! But how is this the same code? If we were on the UI thread, doesn't the UI thread have to block while FilterEnabledForBuilding runs? No, it doesn't, and that's the magic of the await keyword! It cuts your method up into its constituent pieces, much like I did manually with lambdas before. When you run it, only the piece up to the first await actually runs. The rest is passed to FilterEnabledForBuilding as a continuation, which will get called back whenever that method is finished. In the meantime, our thread returns, and can go back to making the UI responsive, or whatever else threads do in their spare time. This is actually a massive simplification, and if you're interested in all the gory details, and speed hacks that the await keyword actually does for you, I recommend Jon Skeet's blog posts about it.

  • creating a list of consecutive integers in c#

  • Cumulative average using data from multiple rows in an excel table

    - by Aaron E
    I am trying to calculate a cumulative average column on a table I'm making in excel. I use the totals row for the ending cumulative average, but I would like to add a column that gives a cumulative average for each row up to that point. So, if I have 3 rows I want each row to have a column giving the average up to that row and then the ending cumulative average in the totals row. Right now I can't figure this out because I'd be having to reference in a formula rows above and below the current row and I'm unsure about how to go about it because it's a table and not just cells. If it was just cells then I know how to do the formula and copy it down each row, but being that the formula I need depends on whether or not a new row in the table is added or not I keep thinking that my formula would be something like: (Completion rate row 1/n) where n is the number of rows up to that point, here row 1, then ((Completion rate row 1 + Completion rate row 2)/n) for row 2 so n=2, and so on for each new row added. Please advise.

  • How do you debug why Windows is slow?

    - by aaron
    I've got Vista Biz and when my machine chugs I think it is because of paging, but I never know how to verify this. Procexp doesn't seem to provide useful information because it appears that nothing is going on when the chugs happen. perfmon seems like it has the counters I need, but I'm never sure what counters I should add to cover the information I want. For perfmon, I prefer numbers that are percents, so I can gauge load. Here are the counters I have up, but they don't always seem to correlate to chugs: - % disk time (logical) - page faults/sec (an indicator of lots of paging activity) - processor/%priviliged time
