• Compiling a c++ project using blas (Fortran) in Matlab mex

  - by Yin Zhu

  I am trying to use a package here. I have no problem compiling it under 64-bit Linux as all the Makefiles are already provides. Only minor changes are needed, which I can handle. However, I have a problem compiling it under 64-bit Windows. I have installed gfortran and also compiled BLAS and CBLAS to their static libraries. The problem is that Matlab mex does not support GCC in windows, so I need to use VC 2008 instead. I found in the Makefile this line is to get the final klr_train.mexw64: klr_train.$(MEX_EXT): klr_train.cpp $(MEX) $(MEX_OPTION) klr_train.cpp ../libklr/libklr.cpp $(CBLASDIR)/lib/LINUX/cblas_LINUX.a $(BLASDIR)/blas_LINUX.a -lgfortran I don't know how to execute this line using VC 2008's command line tool cl. As cl obviously does not support -lgfortran, which I think is used to link some library in gfortran to support BLAS.

• Seemingly useless debugging environment for Android

  - by mikeY

  I've just started debugging my first three line long android app and I can't seem to use the debug tool like I want to. Here's my code: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); int a = 1 / 0; } Now I expect the debugger to halt the thread and show me the line number of statement where the division by zero occurs. No, instead it shows some other method internal to the system for which I have no source. To make the matters worse, there is no exception message either. Prior to this app, I created one which would do something when a button was pressed. If any exception was raised, again no useful line number or exception message would be shown. As of right now, there is no way to debug my app. Any ideas? I'm using the latest SDK along with Eclipse ADT plugin and debugging on a real device (Nexus One).

• What's the best way to do literate programming in Python on Windows?

  - by JasonFruit

  I've been playing with various ways of doing literate programming in Python. I like noweb, but I have two main problems with it: first, it is hard to build on Windows, where I spend about half my development time; and second, it requires me to indent each chunk of code as it will be in the final program --- which I don't necessarily know when I write it. I don't want to use Leo, because I'm very attached to Emacs. Is there a good literate programming tool that: Runs on Windows Allows me to set the indentation of the chunks when they're used, not when they're written Still lets me work in Emacs Thanks! Correction: noweb does allow me to indent later --- I misread the paper I found on it. By default, notangle preserves whitespace and maintains indentation when expanding chunks. It can therefore be used with languages like Miranda and Haskell, in which indentation is significant That leaves me with only the "Runs on Windows" problem.

• Light-weight client/server DB?

  - by OverTheRainbow

  Hello, (This question falls between programming and finding a tool, so I guess I'll ask here in SO since it has more activity than SuperUser.) I like the simplicity of SQLite, but by design, it doesn't support concurrent access. The apps I write don't have heavy needs, so I'd like to avoid heavier solutions like MySQL that are more difficult to deploy (remote customers with usually no computer personnel). Does someone know of a good solution that would offer the following features? Client available for VB.Net applications The server itself doesn't have to be a .Net application. Actually, I'd rather a bare-metal server so that it can run even on embedded Linux hosts with less RAM/CPU than regular PC's Easy install: the client part should either be statically linked inside the client application or be available as a single DLL, and the server should just be a single EXE listening for queries, à la Fossil (http://www.fossil-scm.org) clients can locate the server on the LAN by broadcasting data picked up by the server, so users don't have to write down the IP address and paste it into each client open-source, or moderately priced closed-source Thank you.

• Links to official style guides

  - by User1

  C++ has several types of styles: MFC, Boost, Google, etc. I would like to examine these styles and determine which one is best for my projects, but I want to read from the official style guidebook. Does anyone have an official guide that they typically use? Here are two that I found. I bet there are more: http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml http://www.boost.org/development/requirements.html Note: This is NOT a discussion about which styleis best..only a call for official style guides that people currently use. Please refrain from bashing other style guides that you don't like. Side question: Is there a good tool that can examine source code and tell if it matches a given style guide?

• SQL Server Table locks in long query - Solution: NoLock?

  - by Kovu

  a report in my application runs a query that needs between 5 - 15 seconds (constrained to count of rows that will be returned). The query has 8 joins to nearly all main-tables of my application (Customers, sales, units etc). A little tool shows me, that in this time, all those 8 tables are locked with a shared table lock. That means, no update operation will be done in this time. A solution from a friend is, to have every join in the query, which is not mandetory to have 100% correct data (dirty read), with a NoLock, so only 1 of this 8 tables will be locked completly. Is that a good solution? For a report in which 99% of data came from one table, unlock the less prio tables?

• How to figure out which jars are needed?

  - by Ari

  How can I systematically determine which jars I'll need, and thus should include in my pom.xml file (I'm using maven as my project management tool)? When learning spring, to keep things simple, added all the jars (even the ones I never used) to the classpath. Right now for the most part, I'm guessing which jars to include. For example, I know in my spring configuration file, I have: <tx:annotation-driven /> <context:annotation-config /> <aop:aspectj-autoproxy /> So, I guess I'll need: spring-context-x.x.x.jar, spring-tx-x.x.x.jar, spring-aop-x.x.x.jar Thanks.

• Unlocking Locked Out accounts using PowerShell (not with Quest AD cmdlets)

  - by Jonny

  I'm writing a GUI tool using PowerShell that is able to do most AD related tasks with just a user name and button click. I've done all the usual ones (Create / Remove Users, Create / Remove Security & Distribution Groups, Resetting Passwords, etc) but can't find away of unlocking a "Locked Out" account. I'm trying to do this without using Quest AD cmdlets as I want a more stand alone solution. So I'm wondering whether is possible with plain PowerShell (1.0 or 2.0) in a Windows 2003 Domain. Many thanks.

• Re-send POST request easily - what tools?

  - by Fabien

  I am looking for an easy way to re-send POST request to the server within the browser mainly for debug purposes. Say you have a XHR request which contains POST parameters that is to be send to the server. After having changed the script on the server side, you would like to resent the very same request for analyzing the output. What tool could help? I guess it is a browser's extension. I already tried extension Tamper Data for Firefox which does the job as you can "Replay in browser". But for my taste, it is not enough straight forward, as there are 3 - 4 clicks to get the result of the request. Unfortunately, curl would not be suitable for my needs as my application has a session's cookie.

• How to stop nant exec task putting ( ) around command line

  - by Sam

  I have looked through the nant documentation and sourceforge faq and can't find the answer to this question. The exec task in nant puts ( ) around the command line parameters it generates, so for example this task below would generate: mallow ( -1 ) <exec program="${build.tools.wix}\mallow.exe" workingdir="${build.out.xxx}"> <arg value="-1" /> </exec> The other open source tool I'm using - mallow - cannot handle this. Does anyone know of a way to stop nant putting the ( ) around the arguments? Thanks.

• How to detect code duplication during development ?

  - by David Dibben

  We have a fairly large code base, 400K LOC of C++, and code duplication is something of a problem. Are there any tools which can effectively detect duplicated blocks of code? Ideally this would be something that developers could use during development rather than just run occasionally to see where the problems are. It would also be nice if we could integrate such a tool with CruiseControl to give a report after each check in. I had a look at Duploc some time ago, it showed a nice graph but requires a smalltalk environment to use it, which makes running it automatically rather difficult. Free tools would be nice, but if there are some good commercial tools I would also be interested.

• How to configure build numbers in Visual Studio to enable dll comparison

  - by jaminto

  Hi Everyone- I am building a C# solution in Visual Studio 2008 that has several projects and project dependencies. I am looking for a way to change dll version numbers ONLY when the code that builds the project changes. I currently use Beyond Compare to compare my locally built version to the production file system. The goal is to ONLY deploy updated dlls. I am using autoincrementing version numbers, and each time you open visual studio and do a build, all dll version numbers increment. The same goes for a full solution rebuild and when a different developer does a build and tries to deploy. Is there a way that i can configure Visual Studio to ONLY increment the build number based on changed file contents? Is there an add in that will do this?It seems a binary comparison of these files will also fail because of the different version numbers within the dlls. Does anyone know of a better tool compare only the contents of dlls?Thanks in advance.

• Renaming CSS classes across HTML files

  - by hekevintran

  If I have 100 HTML files that use a set of CSS classes, is there a utility that I can use to intelligently rename the classes? I know that every editor/IDE has a find/replace in project feature. Using sed you can do the same thing. This is not intelligent because it is a simple string replace. I want to know of a tool that actually understands what a CSS class is and how to replace instances of it. I suppose a fancy regular expression can do the same thing.

• Open Graph & Rails not retrieving object's URL

  - by Fred

  I'm using Rails to try and add an action for an object both defined for my app on the open graph. I am using an :after_filter in my controller to call the following after session#create: @graph.put_connections('me', 'workkout:complete', :session => url_for([@plan, @session])) I am getting the following back from Facebook: {"error":{"type":"Exception","message":"Could not retrieve data from URL.","code":1660002}} I have checked that the correct URL is passed to put_connections, and when I visit this URL using Facebook's Lint tool, everything is correct. I can't understand why this isn't working, my only thought is that Facebook is hitting the URL moments before rails has generated the object? - not sure if that's even possible though. Can anyone shed any light on this?

• Why does localization with resx files fail with ZH (chinese) only?

  - by Trey Carroll

  Howdy All, I've been tasked with localizing an English language ASP.NET MVC 2.0 website into 7 additional languages. I've added resource files to the Views Home App_LocalResources folder: Example: Index.resx, Index.es.resx, Index.fr.resx, Index.zh.resx, etc. I have set the CustomTool to PublicResXFileCodeGenerator (Access modifier is Public), Set file as an Embedded Resource, Set a Custom Tool Namespace. The keys ("Name") in all of the files are the same. For 7 languages this works perfectly. If I go into IE 8 settings and change the language to de,fr,it, etc., the page shows the appropriate translated strings. However, when I set the language in the Browser to any of the zh (Simplified Chinese) variants localization completely fails and the English strings are displayed. Is there something special about Simplified Chinese? Japanese and Korean work without problems. TIA, Trey Carroll

• Controlling maximum Java standalone running in Linux

  - by Gnanam

  Hi, We've developed a Java standalone program. We've configured in our Linux (RedHat ES 4) cron schedule to execute this Java standalone every 10 minutes. Each standalone may sometime take more than 1 hour to complete, or sometime it may complete even within 5 minutes. My problem/solution I'm looking for is, the number of Java standalones executing at any time should not exceed, for example, 5 threads. So, for example, before even a Java standalone/thread starts, if there are already 5 threads running, then this thread should not be started; otherwise this would indirectly start creating OutOfMemoryError problems. How do I control this? I would also like to make this 5 thread as configurable. Other Information: I've also configured -Xms and -Xmx heap size settings. Is there any tool/mechanism by which we can control this? I also heard about Java Service Wrapper. What is this all about?

• Is it worthwhile learning about Emacs? [closed]

  - by dole doug

  Hi there Some time ago, I've heard what a great tool Emacs can be. I've read some papers about it and some watched some video too. I've read that emacs is great not only for developers but for usual users too...so i decided to start learning how to use it and wok with it. The problem is that I'm a MS Windows user and I learn in my spare time PHP and C(I also did some products on those languages, but i still considering myself in learning stage). Another problem is that I learn alone (no friends around to ask/learn from them, programming related stuff). Can you give me some tips about how to use those type of tools(especially those written for gnu/unix) with "poor" GUI but rich features? Do you recommend to use the specific windows written applications only and forget about those which come from GNU?

• MD5 file processing

  - by Ric Coles

  Good morning all, I'm working on an MD5 file integrity check tool in C#. How long should it take for a file to be given an MD5 checksum value? For example, if I try to get a 2gb .mpg file, it is taking around 5 mins+ each time. This seems overly long. Am I just being impatient? Below is the code I'm running public string getHash(String @fileLocation) { FileStream fs = new FileStream(@fileLocation, FileMode.Open); HashAlgorithm alg = new HMACMD5(); byte[] hashValue = alg.ComputeHash(fs); string md5Result = ""; foreach (byte x in hashValue) { md5Result += x; } fs.Close(); return md5Result; } Any suggestions will be appreciated. Regards

• Building dictionary of words from large text

  - by LiorH

  I have a text file containing posts in English/Italian. I would like to read the posts into a data matrix so that each row represents a post and each column a word. The cells in the matrix are the counts of how many times each word appears in the post. The dictionary should consist of all the words in the whole file or a non exhaustive English/Italian dictionary. I know this is a common essential preprocessing step for NLP. Does anyone know of a tool\project that can perform this task? Someone mentioned apache lucene, do you know if lucene index can be serialized to a data-structure similar to my needs?

• Microsoft T-SQL to Oracle PL/SQL translation

  - by Michael Prewecki

  I've worked with T-SQL for years but i've just moved to an organisation that is going to require writing some Oracle stuff, probably just simple CRUD operations at least until I find my feet. I'm not going to be migrating databases from one to the other simply interacting with existing Oracle databases from an Application Development perspective. Is there are tool or utility available to easily translate T-SQL into PL/SQL, a keyword mapper is the sort of thing I'm looking for. P.S. I'm too lazy to RTFM, besides it's not going to be a big part of my role so I just want something to get me up to speed a little faster.

• Jythonc missing

  - by mridang

  Hi Guys, I just installed Jython 2.5.1. I want to convert my Python file into Java class file and it is instructed on the website to use the jythonc command-line tool but I can't find it. Does anyone know where I could find it? Basically what i was trying to accomplish is to get my Python code running client-side in a browser and the best way seemed to be by creating an applet using Jython. I don't want to create a desktop application and using Silverlight/IronPython is out of the question. Any other ideas are welcomed. Cheers!

• jQuery pre document ready event

  - by Luke Duddridge

  Hi, I have a list of 179 thumbnail images that I am trying to apply a jQuery lightbox tool to an unorder list of hyper-links. The problem I have is, the jQuery isnt firing until the images have finished downloading, each image is around 23K so on their own, not so big, but as a group this equates to around 4MB. There is a delay on IE (main browser used by clients) of a good 5 seconds before the page has completely downloaded every thumbnail and then allows the jQuery to fire. I have tried putting the jQuery document ready event in various places with no success, and only been able to put a bandaid on by setting the css on the ul to hide using display:none before applying .show() after the lightbox has applied. I was hoping there is a way to make the jQuery scripts fire before all the content has downloaded? Cheers

• Import OLE Object from Access to MySQL

  - by SecretDeveloper

  I have a table in an access table which contains Product entries, one of the columns has a jpg image stored as an OLE Object. I am trying to import this table to MySQL but nothing seems to work. I have tried the MySQL migration tool but that has a known issue with Access and OLE Objects. (The issue being it doesnt work and leaves the fields blank) I also tried the suggestion on this site and while the data is imported it seems as though the image is getting corrupted in the transfer. When i try to preview the image i just get a binary view, if i save it on disk as a jpg image and try to open it i get an error stating the image is corrupt. The images in Access are fine and can be previewed. Access is storing the data as an OLE Object and when i import it to MySql it is saved in a MediumBlob field. Has anyone had this issue before and how did they resolve it ?

• Amazon S3 Add METADATA to existing KEY

  - by Daveo

  In S3 REST API I am adding metadata to an existing object by using the PUT (Copy) command and copying a key to the same location with 'x-amz-metadata-directive' = 'REPLACE' What I want to do is change the download file name by setting: Content-Disposition: attachment; filename=foo.bar; This sets the metadata correctly but when I download the file it still uses the keyname instead of 'foo.bar' I use a software tool S3 Browser to view the metadata and it looks correct (apart from 'Content-Disposition' being all lower case as that's was S3 ask me to sign) Then using S3 Browser I just pressed, then save without changing anything and now it works??? What am I missing how come setting a metadata 'Content-Disposition: attachment; filename=foo.bar;' from my web app does not work but does work from S3 Browser?
