  • Is it possible to install IDLE on Python 2.5 and Ubuntu

    - by broiyan
    Ubuntu Software Center offers versions of IDLE numbered 2.6 and upwards. If I have to use Python 2.5 (because of Google App Engine compatibility), will it be possible to still use IDLE? I am of course assuming that the there is some necessity for the IDLE version number to be the same as the Python version number. Presently, my invocations of IDLE fail because of _tkinter not being found. Likewise it is not found when I try to do an import _tkinter interactively. I then proceeded to install Tcl and Tk and python-tk and one of the IDLE versions being offered (none were labelled 2.5) but _tkinter still does not get imported.

  • Seeking a GUI auto-format feature for T-SQL

    - by dvanaria
    Is there a freely available GUI tool that will allow interaction with Microsoft SQL Server (via T-SQL) that provides an auto-format feature? I constantly find myself writing queries in SQL Query Analyzer (Microsoft’s standard GUI tool for T-SQL) and cutting/pasting the whole thing into SQLyog (a GUI tool for MySQL), where I can press F12 and have it reformatted into an easily readable, industry standard format. I then cut/paste this back into Query Analyzer to execute. I do this all the time at work and haven’t been able to find an alternative. I realize that SQLyog is no longer free software, but what I’m looking for is a specific alternative to a MS SQL Server interface (with auto-formatting). Thanks in advance for your help.

  • Develop applications to mobiles

    - by muek
    Hi there, I have very easy question, but I simply have any idea of the answer. I have developed a small mobile-application using java, for my nokia. The problem is that when installed on my samsung the application simply crashed. Then I tried on my other nokia but different model, and I didn't got the normal behavior. So my question is, does anyone have any idea how companies that develop mobiles applications/games test their software. Does they have to have all models for all mobiles phones??

  • How is Java Platform independent when it needs JVM to run ?

    - by happysoul
    Just started learning Java and I am confused about this whole independent platform thingy. Doesn't independent means that Java code should be able to run on any machine and would need no special software to be installed (JVM in this case has to be present in the machine)? Like, for example, we need to have Turbo C Compiler in order to compile C/C++ source code and then execute it.. The machine has to have the C compiler. guess I am confused..Somebody please explain in simple language or may be direct me to a tutorial that explain things in simple language ? that would be great I am just not getting the concept.

  • Can I allow a write access to a particular registry key without elevation?

    - by 280Z28
    I develop an extension for Visual Studio 2005, 2008, and 2010. The Visual Studio 2005 SDK requires write access to the following registry key during builds. The normal way to handle this run Visual Studio with elevated privileges. The entire issue can be avoided if there's some way I can set permissions to allow access to this particular registry key without elevation: HKLM\SOFTWARE\Microsoft\VisualStudio\8.0Exp Side note: This key is only used for testing Visual Studio 2005 extensions. The issue does not occur on client machines so this is just a workaround for my own development machine.

  • SDL_BlitSurface() not displaying image?

    - by Christian Gonzalez
    So I'm trying to display a simply image with the SDL library, but when I use the function SDL_BlitSurface() nothing happens, and all I get is a black screen. I should also note that I have the .bmp file, the source, and the executable file all in the same directory. //SDL Header #include "SDL/SDL.h" int main(int argc, char* args[]) { //Starts SDL SDL_Init(SDL_INIT_EVERYTHING); //SDL Surfaces are images that are going to be displayed. SDL_Surface* Hello = NULL; SDL_Surface* Screen = NULL; //Sets the size of the window (Length, Height, Color(bits), Sets the Surface in Software Memory) Screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); //Loads a .bmp image Hello = SDL_LoadBMP("Hello.bmp"); //Applies the loaded image to the screen SDL_BlitSurface(Hello, NULL, Screen, NULL); //Update Screen SDL_Flip(Screen); //Pause SDL_Delay(2000); //Deletes the loaded image from memory SDL_FreeSurface(Hello); //Quits SDL SDL_Quit(); return 0; }

  • my realtime network receiving time differs a lot, anyone can help?

    - by sguox002
    I wrote a program using tcpip sockets to send commands to a device and receive the data from the device. The data size would be around 200kB to 600KB. The computer is directly connected to the device using a 100MB network. I found that the sending packets always arrive at the computer at 100MB/s speed (I have debugging information on the unit and I also verified this using some network monitoring software), but the receiving time differs a lot from 40ms to 250ms, even if the size is the same (I have a receiving buffer about 700K and the receiving window of 8092 bytes and changing the window size does not change anything). The phenomena differs also on different computers, but on the same computer the problem is very stable. For example, receiving 300k bytes on computer a would be 40ms, but it may cost 200ms on another computer. I have disabled firewall, antivirus, all other network protocol except the TCP/IP. Any experts on this can give me some hints?

  • what are the advantages of C# over Python

    - by Matt
    I like Python mostly for the great portability and the ease of coding, but I was wondering, what are some of the advantages that C# has over Python? The reason I ask is that one of my friends runs a private server for an online game (UO), and he offered to make me a dev if I wanted, but the software for the server is all written in C#. I'd love to do this, but I don't really have time to do multiple languages, and I was just after a few more reasons to justify taking C# over Python to myself. I'm doing this all self-taught as a hobby, btw

  • Display message when user leaves site

    - by Brian Rasmusson
    Hi, I'm looking for a way to display a message to the user if he leaves my site after only viewing one page. I found this (http://www.pgrs.net/2008/1/30/popup-when-leaving-website) clever solution, but it has a few flaws: staying_in_site = false; Event.observe(document.body, 'click', function(event) { if (Event.element(event).tagName == 'A') { staying_in_site = true; } }); window.onunload = popup; function popup() { if(staying_in_site) { return; } alert('I see you are leaving the site'); } It displays the message also when refreshing the page or using the back button. Do you know a better solution or how to fix it in the above code? I'm no javascript master :) My intention is to add the code on very specific landing pages only, and display the message when people leave the page without downloading my trial software or reading other pages on my site.

  • Is selling a "website screen scraper" illegal?

    - by Yatendra Goel
    I have coded a "website screen scraper" and want to sell it commercially. I know that webpages scraped by the screen scraper are restricted to be scraped by the webmaser of that website. The robots.txt file of the website says that its webpages must not be scraped. So my question is whether selling that screen scraper is a crime or using that screen scraper is a crime in legal terms. I know that this question is related to law but I thought the software experts on SO must also have answer to this question.

  • How to decouple an app's agile development from a database using BDUF?

    - by Rob Wells
    G'day, I was reading the article "Database as a Fortress" by Dan Chak from the excellent book "97 Things Every Software Architect Should Know" (sanitised Amazon link) which suggests that databases should not be designed using an agile approach. There's an SO question on agile approaches and databases "Agile development and database changes" which has some excellent answers covering agile development approaches. In fact, one of the answers supplies a brilliant idea of what's needed for each update of the DB. ;-) But after reading Dan Chak's article, I am left wondering if an agile approach is really suitable for large scale systems. This of course leads on to the question of how best to decouple an agile approach for the application that is interacting with the BDUF database design without adding complicated translation layers in the final design employed? Any suggestions? cheers,

  • Android WebView not respecting scaling percentage...

    - by fiXedd
    I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag: <meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1"> Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%. Ideas?

  • How should I structure my git commits?

    - by int3
    I'm trying to contribute to open source software for the first time, but I'm pretty inexperienced with version control systems. In particular, right now I want to make a number of changes to different parts of the code, but I'm not sure if the maintainer would want to integrate all of them into the master repository. However, the changes I'll be making are independent, i.e. they affect different parts of the file, or parts of different files. How should I go about making the changes? If I make a string of commits on the same branch, will the maintainer be able to pick and choose what he wants from the individual commit? E.g. can he patch in the changes I made in my second commit while ignoring the first one? Or should I make each change in a separate branch?

  • How to make sure web services are kept stable from one release to the next?

    - by Tor Hovland
    The company where I work is a software vendor with a suite of applications. There are also a number of web services, and of course they have to be kept stable even if the applications change. We haven't always succeeded with this, and sometimes a customer finds that a service is not behaving as before after upgrading. We now want to handle this better. In general, web services shouldn't change, and if they have to, at least we will know about it and document the change. But how do we ensure this? One idea is to compare the WSDL files with the previous versions at every release. That will make sure the interfaces don't change, but it won't detect that the behavior changes, for example if a bug is introduced in some common library. Another idea is to build up a suite of service tests, for example using soapUI. But then we'll never know if we have covered enough cases. What are some best practices regarding this?

  • Display On-Screen Television Graphics During Live Broadcasts

    - by ServAce85
    How and with what software do major television companies display on-screen graphics during their programs? For example: On ESPN, how do they produce the news ticker on the bottom (both graphically and from a source code point of view), create and display the scores of sports, and update and show selected stats on the fly? I've looked everywhere I can think of to find the answer, but I am at a loss. That's where you guys (and girls) come in. I hope you can help shed some light on this subject for me. Thanks in advance.

  • How to find an available port?

    - by Roman
    I want to start a server which listen to a port. I can specify port explicitly and it works. But I would like to find a port in an automatic way. In this respect I have two questions. In which range of port numbers should I search for? (I used ports 12345, 12346, and 12347 and it was fine). How can I find out if a given port is not occupied by another software?

  • Programming and art

    - by user353874
    Specialized software does play a major role in every business field. Games provide new realities and are proved child development tools. Communication got a new meaning. Information never traveled so fast. And programming is never referred to as an art form. Why is that? Programming is not romantic and not natural so we don't feel naturally attached to it. Basically, our emotions don't fit programming. But it's really cool and better than art. :D

  • Windows Phone 8 Announcement

    - by Tim Murphy
    As if the Surface announcement on Monday wasn’t exciting enough, today Microsoft announce that Windows Phone 8 will be coming this fall.  That itself is great news, but the features coming were like confetti flying in all different directions.  Given this speed I couldn’t capture every feature they covered.  A summary of what I did capture is listed below starting with their eight main features. Common Core The first thing that they covered is that Windows Phone 8 will share a core OS with Windows 8.  It will also run natively on multiple cores.  They mentioned that they have run it on up to 64 cores to this point.  The phones as you might expect will at least start as dual core.  If you remember there were metrics saying that Windows Phone 7 performed operations faster on a single core than other platforms did with dual cores.  The metrics they showed here indicate that Windows Phone 8 runs faster on comparable dual core hardware than other platforms. New Screen Resolutions Screen resolution has never been an issue for me, but it has been a criticism of Windows Phone 7 in the media.  Windows Phone 8 will supports three screen resolutions: WVGA 800 x 480, WXGA 1280 x 768, and 720 1280x720.  Hopefully this makes pixel counters a little happier. MicroSD Support This was one of my pet peeves when I got my Samsung Focus. With Windows Phone 8 the operating system will support adding MicroSD cards after initial setup.  Of course this is dependent on the hardware company on implementing it, but I think we have seen that even feature phone manufacturers have not had a problem supporting this in the past. NFC NFC has been an anticipated feature for some time.  What Microsoft showed today included the fact that they didn’t just want it to be for the phone.  There is cross platform NFC functionality between Windows Phone 8 and Windows 8.  The demos , while possibly a bit fanciful, showed would could be achieved even in a retail environment.  We are getting closer and closer to a Minority Report world with these technologies. Wallet Windows Phone 8 isn’t the first platform to have a wallet concept.  What they have done to differentiate themselves is to make it sot that it is not dependent on a SIM type chip like other platforms.  They have also expanded the concept beyond just banks to other types of credits such as airline miles. Nokia Mapping People have been envious of the Lumia phones having the Nokia mapping software.  Now all Windows Phone 8 devices will use NavTeq data and will have the capability to run in an offline fashion.  This is a major step forward from the Bing “touch for the next turn” maps. IT Administration The lack of features for enterprise administration and deployment was a complaint even before the Windows Phone 7 was released.  With the Windows Phone 8 release such features as Bitlocker and Secure boot will be baked into the OS. We will also have the ability to privately sign and distribute applications. Changing Start Screen Joe Belfiore made a big deal about this aspect of the new release.  Users will have more color themes available to them and the live tiles will be highly customizable. You will have the ability to resize and organize the tiles in a more dynamic way.  This allows for less important tiles or ones with less information to be made smaller.  And There Is More So what other tidbits came out of the presentation?  Later this summer the API for WP8 will be available.  There will be developer events coming to a city near you.  Another announcement of interest to developers is the ability to write applications at a native code level.  This is a boon for game developers and those who need highly efficient applications. As a topper on the cake there was mention of in app payment. On the consumer side we also found out that all updates will be available over the air.  Along with this came the fact that Microsoft will support all devices with updates for at least 18 month and you will be able to subscribe for early updates.  Update coming for Windows Phone 7.5 customers to WP7.8.  The main enhancement will be the new live tile features.  The big bonus is that the update will bypass the carriers.  I would assume though that you will be brought up to date with all previous patches that your carrier may not have released. There is so much more, but that is enough for one post.  Needless to say, EXCITING! del.icio.us Tags: Windows Phone 8,WP8,Windows Phone 7,WP7,Announcements,Microsoft

  • Is git svn rebase required before git svn dcommit?

    - by allyourcode
    I'm reading about using git as an svn client here: http://learn.github.com/p/git-svn.html That page suggests that you do git svn rebase before git svn dcommit, which makes perfect sense; it's like doing svn update before doing svn commit. Then, I started looking at the documentation for git svn dcommit (I was wondering what the 'd' is about): http://www.kernel.org/pub/software/scm/git/docs/git-svn.html You have to scroll down a bit to see the documentation on dcommit, which says this: Commit each diff from a specified head directly to the SVN repository, and then rebase or reset (depending on whether or not there is a diff between SVN and head). This confuses me, because if you do as the first page says, there will be no changes to pull down from svn once the first part of dcommit finishes. I'm also confused by the part that talks about reset; isn't git reset for removing changes from the staging area? Why would rebase or reset follow (the first part of) a dcommit?

  • How to get generate WSDL using GroovyWS

    - by James Black
    I am implementing SOAP web services for a commercial application, and I am using GroovyWS to speed up the development. But, when I deploy it on Tomcat, I am not using Grails, as the software has it's own J2EE framework, so how I do I get it to react to wsdl requests? Do I need to write a groovy-based servlet? Ideally I would like the WSDL generated upon request, so I can easily change the interface and see the change. It seems I will miss the annotations that JAX-WS provides for, though, to help fine-tune the WSDL.

  • COM+ Connection Pooling Doesn't Appear to be working on SQL Server 2005 Cluster

    - by kmacmahon
    We have a COM+ Data Layer that utilized Connection Pooling. Its deployed to 3 clusters, 2 SQL Server 2000 and 1 SQL Server 2005 environment. We noticed today that our monitoring software is reporting Thousands of Logins per minute on the SQL Server 2005 box. I did some tracing in both environments and profiler is reporting this for the 2000 boxes: sp_reset_connection SQL CALL sp_reset_connection SQL CALL sp_reset_connection SQL CALL and this for the 2005 box: Audit Logout sp_reset_connection Audit Login SQL CALL Audit Logout sp_reset_connection Audit Login SQL CALL Audit Logout sp_reset_connection Audit Login SQL CALL Is there some sort configuration for SQL Server 2005 different from SQL Server 2000 that we might be missing that would be creating this issue?

  • Performance statistics hooks

    - by tinny
    Lets be honest, most software that developers produce has quite modest performance requirements. E.g. Systems perhaps serving 100's of requests per second, if that. But lets assume for a moment (or even dream) that you where perhaps involved in the "next big thing" (whatever that means) and you wanted to put some sort of performance statistics logging in place to help you out when all those users come flying in. Performance statistics logging, how would you approach this requirement? Perhaps you would use some sort of generic framework for this? Or roll your own solution? What would you log? How granular? Or would you not even bother putting anything in place and rather deal with this issue when it actually became an issue? It would be really interesting to hear your thoughts on this topic.

  • continuous integration web service

    - by Josh Moore
    I am in a position where I could become a team leader of a team distributed over two countries. This team would be the tech. team for a start up company that we plan to bootstrap on limited funds. So I am trying to find out ways to minimize upfront expenses. Right now we are planning to use Java and will have a lot of junit tests. I am planing on using github for VCS and lighthouse for a bug tracker. In addition I want to add a continuous integration server but I do not know of any continuous integration servers that are offered as a web service. Does anybody know if there are continuous integration servers available in a software as a service model? P.S. if anybody knows were I can get these three services at one location that would be great to know to.

  • Longlasting Macport installation

    - by Werner
    Hi, I use Macports on Mac OSX to install some software. But there are somethings that I find very strange. For instance, yesterday I installed some app. and the it needed to get gcc43 and compile completely from source! It took a lot of time, although now everything works right. I understand that compilation of everything in the gentoo spirit is eomthing nice, but in the Mac case, not necessary. There are ony sole hardware variations, so it will be easier to get the binaries. I wonder if Macporst can be forced to get the binaries when available and therefore avoid these time consuming compilations. Thanks
