• How do you make an installer for your python program

  - by Malcolm2608

  Im new to python, but I was thinking about making a program with python to give to my friends. They don't know much about computers so if I asked them to install python by them selves they couldn't do it, but what if I could make an installer that downloads some version of python that only has what is needed for my file to run and make an exe file that would run the .py file in its own python interpreter . I also did a Google search and saw the freezing applications I could use to make the code into exe files to distribute (cx_freeze I use python 3.2), but not all of my friends have Windows computers and I rather Have my program so in each new version it auto updates by making a patch to .py file and not completely re-installing it .

• In a web app, is it wise to give log files ".txt" suffix?

  - by Pekka

  I am building a logging mechanism in a web application. Being a Windows man, I tend to give files with textual content the .txt ending. The suffix is automatically registered to be opened in a text editor in any Windows environment, and is just a nice convention. The app is going to be redistributed, and running mostly on Linux, though. The Linux convention for log files is .log. Is there any good reason on the Linux end, besides convention, why I should use .log? Any filters, real-life applications that could become relevant and that will work only with a .log suffix? Or can I merrily call it error_log.txt?

• JavaFX media player in mobile

  - by cancelledout

  Does anyone have any tutorials in playing videos in javafx applications in mobile? My codes strangely work only in desktop execution. But the official site of JavaFX says it plays in mobile phones.

• Reading and writing to SysV shared memory without synchronization (use of semaphores, C/C++, Linux)

  - by user363778

  Hi, I use SysV shared memory to let two processes communicate with each other. I do not want the code to become to complex so I wondered if I really had to use semaphores to synchronize the access to the shared memory. In my C/C++ program the parent process reads from the shared memory and the child process writes to the shared memory. I wrote two test applications to see if I could produce some kind of error like a segmentation fault, but I couldn't (Ubuntu 10.04 64bit). Even two processes writing non stop in a while loop to the same shared memory did not produce any error. I hope someone has experience concerning this matter and can tell me if I really must use semaphores to synchronize the access or if I am OK without synchronization. Thanks

• iOS and Infrared

  - by Mustafa

  Is it possible to communicate with an Infrared device (USB Infrared, TV, Mobile Phone, etc) using iOS (iPhone or iPad)? Well, i know it's possible, since there are many remote/universal remote applications in the AppStore. I basically want to know how? What are the limitations and requirements? What kind of additional hardware is required? If it's available in the market? Which protocols should i know about? Which iOS libraries can help me in the process. Can anyone point me in the right direction. Thanks.

• how to insert the correct activex object in a MFC dialog

  - by kellogs

  More exactly, the web browser control. In a WM6 dialog based MFC project. This is driving me nuts. Mr Google does not know a thing on this matter. I have tried embedding the "Microsoft Webbrowser Control" in my dialog box but at runtime I get some class not register error. I have heard that this happens because "Microsoft Webbrowser Control" is the windows desktop control, not the windows mobile one. Otherwise, I find it quite hard to believe that this control is really not registered even on the emulator (if it really wasn't registered, PIE would not start). Anybody used the webbrowser engine in a WM(6) MFC applications ? Even a CLSID would help... Thank you

• Where can I get free real-time stock data?

  - by Jared

  Does anyone know of a way to obtain free real-time stock data or near real-time stock data? I'd like to do this since I'm interested in the financial market, not for use in investment applications which is why I'm looking for something free. I've tried the Perl module Finance::YahooQuote but some of the fields such as last trade time appear to be broken. I've looked at the historical data but it doesn't fit my needs since I'd like to monitor the movements of the markets and stocks during the trading day not just open and close. I've also looked at http://www.opentick.com but they aren’t accepting new accounts and I can't find a timeline for when their network upgrade will be complete.

• Microsoft SQL Server 2008 Web Edition: is it suitable for "closed" websites?

  - by micha12

  Can Microsoft SQL Server 2008 Web Edition be used in "closed" websites, which are hosted on the Internet, but require users to log in? We are developing a web application for banks. This is a website for clients of the bank; it allows clients to log in and view information on their personal banking accounts, stock portfolios, etc. Can this web app use SQL Server 2008 Web Edition? Here is information on this edition of SQL Server: http://www.microsoft.com/sqlserver/2008/en/us/web.aspx It is said on this page that Web Edition can be used only on "public and Internet accessible ... Web applications". Technically, the web app we are developing is public and Internet accessible - although it requires authentication. Won't using Web Edition in our web app violate SQL Server license terms? Thank you.

• Why is silverlight so slow? (Especially when compared to Flash)

  - by Sahat

  I hope I don't have to explain what is Silverlight to SO community. Anyway TemplateMonster.com has recently released new Silverlight themes that have been ported from Flash. Silverlight Templates | Template Monster I've noticed a significant lag on my Macbook Pro 13" in loading the template page in Silverlight. And not just Template Monster templates but other silverlight applications on the web as well. Now why is that? I've been hearing how great Silverlight is and how it's a great business platform blah blah blah. And now Microsoft plans to build Windows Phone 7 on top of Silverlight framework. As much as I want to praise Silverlight, so far it's been nothing but a disappointment to me. Could someone enlighten me, what is so great about Silverlight, and why should I put up with that starting up lag? Silverlight was really next up on my "stuff to learn" list this summer, but now I am not so sure...

• Is there a way to preserve HTML Formatting in LiveDocX?

  - by Peter Schultheiss

  I have a large amount of content stored in a database as XHTML. I need to be able to pull this formatted content into a simple LiveDocX template with the formatting (bold, italic, bulleted lists, etc) preserved. Is this possible? If so, can anybody post a working example or link to an article? If not, are there other applications that I could look into? The client needs to be able to export content in the .doc/.docx file format. Thanks, Peter

• Finding final/effective web.config values (from inherited configurations)

  - by gregmac

  Are there any apps that can show the final configuration as applied to a particular application directory? What I'm picturing is something along the lines of FireBug's CSS viewer. Basically, it should show the equivalent single web.config file (as if you only had one), with all the values that apply to the directory in question, with each element (or even attribute) annotated with its source (the real .config file it came from). This would greatly help deploying applications into foreign environments (eg, customer sites) where they sometimes have strange configs, that add in global includes (eg, they put the include in machine.config, instead of the web.config for that app) or have allowOverride=false, etc.

• C# .NET Controls for docked tool windows?

  - by Brett Powell

  I was using Qt with C++ to develop my GUI applications, but I have recently switched to try out C# .NET as it is much easier to do what I need to. I was wondering what controls I need to be using for a few things and if they exist for C# .NET or if I need to do something custom/special. If you look in that screenshot, I want to do something similar to how they have each tool window grouped into its own docking area with the option of closing it or breaking it out of the layout so it can be dragged. I am talking about the tool windows titled "Groups", "Resources", "Tools", etc. I also want to make these tool windows stay in the same place when the main window is resized. Qt has spring like widgets that will let you create a UI that keeps its shape when the window is resized. Does anything like this exist in C# .NET?

• How to build a Video Broadcaster, which can handle more than 20,000 viewers

  - by Gaurav Srivastava

  I want to broadcast Video from a web cam, over internet. The problem is, the Video will be viewed live by more than 20,000 people (expected). I have a very little experience with Red5 Broadcasting. I did some broadcasting using Red5 and Flash. It works fine for 1 or 2 viewers i.e. it is great for personal chatting/ video conferencing applications. But, when the number of viewers increases, the delay in Broadcasting also increases. I am experiencing a Delay addition of about 0.5 Seconds for every new user who joins the broadcast. Can any one suggest me some, better technologies on which I can work out this Live Broadcasting. I don't want to use http://www.ustream.com; I want to create one of my own, such tool. But thats always the last solution.

• Generating changelogs from commit-comments - bad idea?

  - by Adam Asham

  I work for a small company (<10 developers) where we use Svn and to some extent Git. We have no release system implemented. We don't tag our applications with a release numbers so as you can imagine, we don't keep track of changes between releases very well. With this in mind I've been thinking about generating changelogs from the commit-comments. It doesn't have to be an awful idea if you implement guidelines for how to write comments. Or am I fooling myself thinking that colleagues will follow these guidelines? Most of them don't bother adding comments today but I'm hoping that will change if they become aware of how to formulate themselves and that you don't have to comment on every single commit. Or would we it be more wise to gather information from our bug/project managing software and write the changelogs manually (which unfortunately is something nobody wants to do)?

• Caching using hibernate

  - by Subhendu Mahanta

  I have 2 applications.First one is a web application through which we provision reference data.Second one is an ESB based application where the reference data is used.The reference data changes but not very frequently.We needed to cache the reference data.The web application( I am not the owner) used hibernate. But my ESB based application did not.We only used EHCache. When reference data is changed by the independent web application that needs to be reflected in ESB application.We implemented using message queue - that is when reference data changes web application sends a message to the message queue.Our ESB application listens to that message & clears the cache & caches the data once again.This works.But it is time intensive.How can I use Hibernate to improve the situation? Regards, Subhendu

• How to profile a silverlight application?

  - by rudigrobler

  Is their any profilers that support Silverlight? I have tried ANTS (Version 3.1) without any success? Does version 4 support it? Any other products I can try? Updated since the release of Silverlight 4, it is now possible to do full profiling on SL applications... check out this article on the topic At PDC, I announced that Silverlight 4 came with the new CoreCLR capability of being profile-able by the VS2010 profilers: this means that for the first time, we give you the power to profile the managed and native code (user or platform) used by a Silverlight application. woohoo. kudos to the CLR team. Sidenote: From silverlight 1-3, one could only use things like xperf (see XPerf: A CPU Sampler for Silverlight) which is very powerful to see the layout/text/media/gfx/etc pipelines, but only gives the native callstack.) From SilverLite (PDC video, TechEd Iceland, VS2010, profiling, Silverlight 4)

• Project organization in perforce

  - by Chupa

  Hello. I created several web applications that use the same static files (css, js, images). When I use svn for version control, I use an external repository (svn: externals) to add files to the current project. For example: - Project_1 ---- Webapp -------- Static (external to static's repo) - Project_2 ---- Webapp -------- Static (external to static's repo) I could easily use it in their web pages by adding a link like /static/ ... But now our company has moved to perforce. How can I support the current structure? We also use maven, I think to pack these files as a jar and use as a dependency, but then my editor (idea) does not see that this dependence are js-scripts and styles. And i need to repackage and deploy jar file when create minor changes. How to use maven correctly?

• Why does Windows 7 change encoding of characters in runtime?

  - by LukLed

  I have a delphi form: and my code: when I run this form in Windows 7, I see: In design time, form had polish letters in first label, but it doesn't have them in runtime. It looks ok on Vista or Windows XP. When I set caption of second label in code, everything works fine and characters are properly encoded. First 5 codes of top label on Windows 7: 65 97 69 101 83 First 5 codes of top label on Windows Vista/XP: 165 185 202 234 140 First 5 codes of bottom label on every system: 165 185 202 234 140 Windows 7 changes encoding, why? My system settings seem to be ok. I have proper language set for non-unicode applications in control panel.

• NET Framework Validation Library

  - by Kane

  As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

• Rails with DB2 and multiple schemas

  - by GNUMatrix

  I have a 'legacy' DB2 database that has many other applications and users. Trying to experiment with a rails app. Got everything working great with the ibm_db driver. Problem is that I have some tables like schema1.products, schema1.sales and other tables like schema2.employees and schema2.payroll. In the ibm_db adapter connection, I specify a schema, like schema1 or schema2, and I can work within that one schema, but I need to be able to easily (and transparently) reference both schemas basically interchangeably. I don't want to break the other apps, and the SQL I would normally write against DB2 doesn't have any of these restrictions (schemas can be mixed in SQL against DB2 without any trouble at all). I would like to just specify table names as "schema1.products" for example and be done with it, but that doesn't seem to jive with the "rails way" of going about it. Suggestions?
