• How important is ticket/bug format?

  - by Fedyashev Nikita

  I've heard many Flame wars about ticket's format: how important is it how it has to be structured what parts has it contain Sometimes, that looks like people want to force other team members to adopt his format, even if it is very similar: steps to reproduce what I see what I have to see explanation Or something like this. Usually they don't offer to change add/delete some section from the ticket, but more like change one's section name, or position. What do you think about it? How to find the best solution(if exists...) and common sense?

• Cross-platform configuration, options, settings, preferences, defaults

  - by hippietrail

  I'm interested in peoples' views on how best to store preferences and default settings in cross-platform applications. I primarily work in Perl on *nix and Windows but I'm also interested in the bigger picture. In the *nix world "dotfiles" (and directories) are very common with system-wide or application default settings generally residing in one path and user-specific settings in the home directory. Such files and dirs begin with a dot "." and are hidden by default from directory listings. Windows has the registry which also has paths for defaults and per-user overrides. Certain cross-platforms do it their own way, Firefox uses JavaScript preference files. Should a cross-platform app use one system across platforms or say dotfiles on *nix and registry on Windows? Does your favourite programming language have a library or module for accessing them in a standard way? Is there an emerging best practice or does everybody roll their own?

• Should non-English member names be changed to English?

  - by M.A. Hanin

  Situation: Automatically generated memebers, such as MenuStrip items, have their (automatically generated) names based on the text entered when the item was created. My most common situation is creating a menu-strip and adding menu-items by entering their text (using the graphical designer). Since my GUI is in Hebrew, all these members have a name which contains a Hebrew string. Something like "(hebrew-text)ToolStripItem". When I create event handlers, the event handlers "inherit" the hebrew text: "(hebrew-text)ToolStripMenuItem_Click". This actually works well, IntelliSense has no problem with Hebrew text, and so does the compiler. The question is: should I change these names (or prevent them from being created in the first place)? What are the possible consequences of keeping those names?

• phonegap crossplatform redirection to local file

  - by Marco Gagliardi

  Hi I'm developing a phonegap + JQueryMobile app, which should be correctly executed on Android, iOs and WindowsPhone as well. I need to exploit an external service wich requires one callback url to redirect the app to in case of success, and one in case of error (pretty common situation. In my case both will be local files, say www/success.html and www/error.html). Of course I could write different paths for each device (e.g. file:///android_asset/www/success.html on Android), but i'm wondering if the framework provide a more simple elegant solution. So the questions is, how can i get a unique absolute URL wich allows me to perform a cross-platform HTTP redirection from a remote web page to a local file within a phonegap application? Thanks

• Is there an easy way to sign a C++ CLI assembly in VS 2010?

  - by jyoung

  Right now I am setting the Linker/Advanced/KeyFile option. I am getting the "mt.exe : general warning 810100b3: is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly.". Reading from the web, it sounds like I have to set the delay signing option, download the SDK, and run sn.exe as a post build event. Surely there must be an easier way to do this common operation in VS2010?

• Conseqences of assigning self

  - by Vegar

  Hi, Found a piece of code today, that I find a little smelly... TMyObject.LoadFromFile(const filename: String); begin if fileExists(filename) then self := TSomeObjectStreamer.ReadObjectFromFile(filename); end; If this code works, it will atleast leak some memory, but does it work? Is OK to assign to self in this manner? What if the streamed object is of a different subclass then the original self? What if the streamed object is of a different class with no common ancestore to the original self?

• Strategy to structure a search index in a relational database

  - by neilc

  I am interested in suggestions for building an efficient and robust structure for indexing products in a new database I am building (i'm using MySql) When a product is entered through the form there are three parts I am interested in indexing for searching purposes. The product title The product description Tags The most important is title, followed by tags, followed by the description. I was thinking of using the following structure CREATE TABLE `searchindex` ( `id` INT NOT NULL , `word` VARCHAR( 255 ) NOT NULL , `weighting` INT NOT NULL , `product_id` INT NOT NULL , PRIMARY KEY ( `id` ) ) Then each time a product is created I would split apart the title, description and tags (removing common words) and award them a weighting. Then it is trivial to select out the words and corresponding products and order them by weighting. Is there a better way to do this? I would be worried that this strategy would slow down over time and as the database filled up.

• Possible to distribute an MPI (C++) program accross the internet rather than within a LAN cluster?

  - by Ben

  Hi there, I've written some MPI code which works flawlessly on large clusters. Each node in the cluster has the same cpu architecture and has access to a networked (i.e. 'common') file system (so that each node can excecute the actual binary). But consider this scenario: I have a machine in my office with a dual core processor (intel). I have a machine at home with a dual core processor (amd). Both machines run linux, and both machines can successfully compile and run the MPI code locally (i.e. using 2 cores). Now, is it possible to link the two machines together via MPI, so that I can utilise all 4 cores, bearing in mind the different architectures, and bearing in mind the fact that there are no shared (networked) filesystems? If so, how? Thanks, Ben.

• What's the best way to handle web.config file versions in ASP.Net?

  - by MusiGenesis

  I have an ASP.Net web site (ASPX and ASMX pages) with a single web.config file. We have a development version and a production version. Over time, the web.config files for development and production have diverged substantially. What is the best practice for keeping both versions of web.config in source control (we use Tortoise SVN but I don't think that matters)? It seems like I could add the production web.config file with a name like "web.config.prod", and then when we turnover all the files we would just add the step of deleting the existing web.config and renaming web.config.prod to web.config. This seems hackish, although I'm sure it would work. Is there not some mechanism for dealing with this built in to Visual Studio? It seems like this would be a common issue, but I haven't found any questions (with answers) about this.

• Calculating the pixel size of a string with Python

  - by Aristide

  I have a Python script which needs to calculate the exact size of arbitrary strings displayed in arbitrary fonts in order to generate simple diagrams. I can easily do it with Tkinter. The problem is the results seem to depend on the version of Python and/or the system. import Tkinter as tk import tkFont root = tk.Tk() times12 = tkFont.Font(family="times",size=12) print times12.metrics("linespace"), print times12.measure("Hello world") times24 = tkFont.Font(family="times",size=24) print times24.metrics("linespace"), print times24.measure("Hello world") Python 2.5 on Mac OS X gives the actual pixel measurements: 12 57 24 116 Python 2.6.1 on Mac OS X gives: 14 58 27 115 Python 2.6.3 on Windows XP gives: 19 71 36 154 Such a need being quite common, I suspect I did something wrong. Any idea?

• open source project requirements

  - by skidding

  I know it's a very common question, but I don't see a previous one to be asked, since I'm interested in the basic steps, nothing in particular. It's the first time I want to license one of my projects, and it turns out, I don't know much about it. Let's say I want to use the MIT License. Do I just take the definition and paste it into my files? Does it need to be in ALL the files, or just one? or? I don't want any fancy rights so MIT has been recommended to me, do you suggest something else? I'm looking for impartial opinions. Thanks. What other aspects must I take into account? It's PHP, btw.

• How do I branch an individual file in SVN?

  - by Michael Carman

  The subversion concept of branching appears to be focused on creating an [un]stable fork of the entire repository on which to do development. Is there a mechanism for creating branches of individual files? For a use case, think of a common header (*.h) file that has multiple platform-specific source (*.c) implementations. This type of branch is a permanent one. All of these branches would see ongoing development with occasional cross-branch merging. This is in sharp contrast to unstable development/stable release branches which generally have a finite lifespan. I do not want to branch the entire repository (cheap or not) as it would create an unreasonable amount of maintenance to continuously merge between the trunk and all the branches. At present I'm using ClearCase, which has a different concept of branching that makes this easy. I've been asked to consider transitioning to SVN but this paradigm difference is important. I'm much more concerned about being able to easily create alternate versions for individual files than about things like cutting a stable release branch.

• What tool/framework to use for technical documentation?

  - by Pangea

  We develop products and frameworks to be used with in our organization. I am looking for programmer friendly documentation tools. I have researched on few options sometime back but couldn't decide which one to use. I am looking for suggestions from the people who already used these tools. docbook: springframework and hibernate use this format and this looks good. but I believe they have customized the default xslt/stylesheet. Can I copy and use their xslt and css (ofcourse with colors and images changed). Can I integrate the doc generation using maven? wiki: this is not friendly to the technical document writers and the documentation doesn't look professional. versioning is also not possible I believe word docs: this is what we use currently but it is hard to link and reuse common documents. DITA?

• Why should I use a container div in HTML?

  - by lara.robertson

  I am currently learning html/css, and have noticed a common technique is to place a generic container div in the root of the body tag: <html> <head> ... </head> <body> <div id="container"> ... </div> </body> </html> Is there a valid reason for doing this? Why can't the css just reference the body tag?

• Restart Delphi Application Programmatically

  - by Smasher

  It should not be possible to run multiple instances of my application. Therefore the project source contains: CreateMutex (nil, False, PChar (ID)); if (GetLastError = ERROR_ALREADY_EXISTS) then Halt; Now I want to restart my application programmatically. The usual way would be: AppName := PChar(Application.ExeName) ; ShellExecute(Handle,'open', AppName, nil, nil, SW_SHOWNORMAL) ; Application.Terminate; But this won't work in my case because of the mutex. Even if I release the mutex before starting the second instace it won't work because shutdown takes some time and two instance cannot run in parallel (because of common resources and other effects). Is there a way to restart an application with such characteristics? (If possible without an additional executable) Thanks in advance.

• FORMSOF Thesaurus in SQL Server

  - by Coolcoder

  Has anyone done any performance measures with this in terms of speed where there is a high number of substitutes for any given word. For instance, I want to use this to store common misspellings; expecting to have 4-10 variations of a word. <expansion> _{administration} _{administraton} _aministraton </expansion> When you run a fulltext search, how does performance degrade with that number of variations? for instance, I assume it has to do a separate fulltext search performing an OR? Also, having say 20/30K entries in the Thesaurus xml file - does this impact performance?

• Cant open Nerd Dinner 1.0 VS 2008 SP1 MVC 2

  - by josephj1989

  I was trying to download some ASP.NET MVC Sample application to learn MVC. I tried Music Store and TownHall but they wont open in my VS2008.So I tried the common Nerddinner 1.0 but it gives error "The project Type is not supported by this installation" . I tried the 3rd Method suggested in the following post http://stackoverflow.com/questions/1002907/cant-open-nerddinner-project-in-vs2008 This is about changing the project type GUIDS.Now the project loads but when I run it throws an exception <add assembly="System.Web.Mvc, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31BF3856AD364E35" /> I presume this is happening because the Nerddinner 1.0 is for MVC 1.0 and I have MVC 2.0 installed. How do I proceed now. I have spent a lot of time trying to get an MVC application working on my PC. I am happy if I can get any properly architected , MVC application of medium to high complexity to work on my PC. thanks

• PHP Dynamic Breadcrumb

  - by Adrian M.

  Hello, I got this code from someone and it works very well, I just want to remove the link from the last element of the array: //get rid of empty parts $crumbs = array_filter($crumbs); $result = array(); $path = ''; foreach($crumbs as $crumb){ $path .= '/' . $crumb; $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb)); $result[] = "<a href=\"$path\">$name</a>"; } print implode(' > ', $result); This will output for example: Content Common File I just want a to remove the link from the last item - "File" to be just plain text.. I tried myself to count the array items and then if the array item is the last one then to print as plain text the last item.. but I'm still noob, I haven't managed to get a proper result.. Thank you!

• Visual Studio 2010 "Not enough storage is available to process this command"

  - by Daniel Perez

  I'm fighting with VS 2010 and this error that seems to be very common in previous versions, but it looks like not everyone is having it in the latest version. I've got VS 2010 SP1 and I'm getting this error quite often. The problem is that it's not even enough to restart VS in order to make it go away, I usually have to restart my pc, and i'm losing a lot of time doing this (it's quite frequent) I've got Windows 7 32bits (can't upgrade to 64 bits, the company doesn't allow it), and I can't do things like creating another solution (please don't reply this :) ) I've used the command to make devenv.exe LARGEADDRESSAWARE, but the error keeps on happening My virtual memory size is set to automatic, and the weird thing is that VS doesn't even take 2gb of ram, so I don't know if the error is really because it's lacking memory, or if it's some bug in the program any ideas, things to try, something?

• SSH Password/User problem with Cygwin sshd service

  hello I just set up SSHd through Cygwin on a Windows XP Pro box overseas using a RAT and discluded the openssh package from the install. I ran the cywin shell (from c:\cywin) and ran Now, It's under a port I know is safe and fowarded properly, but I won't share it's number. It's not a common port, but it's under 40000. Firewalls are off etc etc. I'm on the first Admin account made on the box.

I know my ports etc are fine. Any possible problems, as i really need this tunnel up :P

• mediawiki markup equivalent of WMD live-previewing editor? (not WYSIWYG)

  - by Justin Grant

  Anyone have a recommendation for an editor like the WMD editor, but using MediaWiki markup instead of Markdown? Our site is already using MediaWiki markup but we want a slicker editor without changing markup completely. Requirements include: live preview of formatted text underneath the markup you're typing a toolbar for common formatting (bold, italic, links, bullets, numbered-list, code, etc) keyboard shortcuts for each toolbar button (e.g. CTRL+B for bold) Undo/redo via keyboard shortcuts (CTRL+Z/CTRL+Y) or toolbar buttons works well in the usual set of popular browsers (including IE6!) open-source would be preferred I've found a few options at http://www.mediawiki.org/wiki/WYSIWYG_editor, but all of these seem to be WYSIWYG editors which is not exactly what I want since full-on WYSIWYG editors tend to be bug-prone and complicate working at the markup level. Instead we want a plain-text markup editor with a client-side previewer, plus some UI niceties (toolbar, undo, keyboard shortcuts) to make editing markup easier.

• Using a CMYK PSD without Photoshop

  - by 64BitBob

  I have run into a common, yet difficult problem. I do not use Photoshop for image manipulation. Since all my work is web-based, GIMP does what I need in 99% of the situations. The problem is that I occasionally receive PSD files with CMYK encoding rather than RGB encoding. These files will not open in GIMP, nor will they convert in ImageMagick. Has anyone found a good solution for converting CMYK files to RGB files (either PSD format or a flat format like PNG) that does not involve the use of Photoshop? Say a plug-in for GIMP or a standalone utility?

• getResourceAsStream not loading resource in webapp

  - by mangst

  I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

• Question about best practices and Macros from the book 'C++ Coding Standards'

  - by Victor T.

  From Herb Sutter and Andrei Alexandrescu's 'C++ Coding Standards', Item 16: Avoid Macros under Exceptions for this guideline they wrote: For conditional compilation (e.g., system-dependent parts), avoid littering your code with #ifdefs. Instead, prefer to organize code such that the use of macros drives alternative implementations of one common interface, and then use the interface throughout. I'm having trouble understanding exactly what they mean by this. How can you drive alternate implementations without the use of #ifdef conditional compile macro directives? Can someone provide an example to help illustrate what's being proposed by the above paragraph? Thanks

• Should I catch exceptions thrown when closing java.sql.Connection

  - by jb

  Connection.close() may throw SqlException, but I have always assumed that it is safe to ignore any such exceptions (and I have never seen code that does not ignore them). Normally I would write: try{ connection.close(); }catch(Exception e) {} Or try{ connection.close(); }catch(Exception e) { logger.log(e.getMessage(), e); } The question is: Is it bad practice (and has anyone had problems when ignoring such exeptions). When Connection.close() does throw any exception. If it is bad how should I handle the exception. Comment: I know that discarding exceptions is evil, but I'm reffering only to exceptions thrown when closing a connection (and as I've seen this is fairly common in this case). Does anyone know when Connection.close() may throw anything?
