• Managing the localization of Java properties files

  - by andri

  I have a Web application written in Java that is targeting several countries, all of which speak different languages (and more often than not, several languages -- that's Europe for you). We have a bunch of .properties files that hold the localized strings, and our current procedure is to e-mail the language-specific files to our partners for updating before doing major updates. However, this process is rather error-prone, as sometimes people forget to translate new strings and sometimes new strings don't get added to every language file, thus small mistakes get through very easily. Does anyone know of any existing software that could help us clear this mess? At a bare minimum, I'm thinking of something that would allow you to load a master file (for example, in English), a localized file and then would highlight the keys that were added to or removed from the master file.

• Captcha Alternative, how secure?

  - by aslum

  I do the web page for my local library, and I was thinking it might be kind of appealing to have a "custom" captcha based on book covers. So serve up one of several dozen book covers, and have the patron filling out the form type the book title to prove they're human. Assuming I stripped the title/author info from the image and filename, would that be enough? Would the fact that it was a unique system on a fairly small website be enough to make it effective? Just how tricky are the spam bots these days? Would having the image name be the ISBN # be too obvious?

• Will .NET 4.0 apps work on Win 2008 R2 Server Core?

  - by markus

  When Windows Server 2008 R2 was launched, the "server core" edition started to become useful to me, because it lets me deploy .NET background applications isolated on their own virtual machine instance with only a small fraction of all the disk space overhead of a default Windows Server installation, and very few Windows Updates. It comes with a subset of .NET 3.5 SP1 integrated (as an optional feature). Now that .NET 4.0 is released, the redistributables explicitly state that it's not support on Server Core. Any chance that there will be a separate download available for Server Core (e. g. without WPF) any time soon, has anybody heard about it?

• Listening to another window resize events in C#

  - by Steve

  Hi all I am implementing a small application (observer) that needs to "attach" itself to the bottom of another window (observed). The latter is not a window inside the application. At this moment I solved by getting the hWnd of the window and querying periodically in a thread the location of the observed window, moving the observer window accordingly. However this is a very inelegant solution. What I would like to do is to listen to the resize event of the observed window so that the observer will react only when necessary. I assume I should use a hook, and I found plenty of ways of doing it, but my lack of knowledge of the C WinAPI is blocking me in understanding which hook I need to create and how (pinvoke/parameters/etc). I'm pretty sure this is quite trivial, and some of you familiar with C/C++ and WinAPI will have the answer ready at hand ;) Thanks

• Bash variable kills script execusion

  - by Kyle Terry

  Sorry if this is better suited at serverfault, but I think it learns more towards the programming side of things. I have some code that's going into /etc/rc.local to detect what type of touch screen monitor is plugged in and changes out the xorg.conf before launching X. Here is a small snippet: CURRENT_MONITOR=`ls /dev/usb | grep 'egalax_touch\|quanta_touch'` case $CURRENT_MONITOR in '') CURRENT_MONITOR='none' ;; esac If one of those two touch screens is plugged in, it works just fine. If any other monitor is plugged in, it stops at the "CURRENT_MONITOR=ls /dev/usb | grep 'egalax_touch\|quanta_touch'." For testing I touched two files. One before creating CURRENT_MONITOR and one after CURRENT_MONITOR and only file touched before is created. I'm not a bash programmer so this might be something very obvious.

• Flex Framework vs. Micro-Architecture

  - by droboZ

  I'm in the process of choosing a framework for my flex development, and one of the questions that was asked about a framework was "is this a framework or a micro-architecture"? Can someone clarify what's the difference? What exactly is a framework, and when can we start calling what we have a framework? I work with FlexBuilder3 (now called FlashBuilder4) and have a lot of standard things that I do for almost all projects, and components that I created for easy re-use. Some are very very small, but the benefit of a 1-liner has been immense for me instead of repeating the code over and over. So in the framework/micro-architecture scheme, can I say that these are my internal in-house framework or are they part of a micro-architecture? Trying to understand this topic better.

• I'm asked to tune a long starting app into a short time period

  - by Jason

  Hi, I'm asked to shorten the startup period of a long starting app, however I have also to obligate to my managers to the amount of time i will reduce the startup - something like 10-20 seconds. As i'm new in my company I said I can obligate with timeframe of months (its a big server and I'm new and i plan to do lazy load + performance tuning). that answer was not accepted I was required to do some kind of a cache to hold important data in another server and then when my server starts up it would reach all its data from that cache - I find it a kind of a workaround and i don't really like it. do you like it? what do you think I should do? any suggestions? PS when i profiled the app i saw many small issues that make the startup long (like 2 minutes) it would not be a short process to fix all and to make lazy load. Any kind of suggestions would help. language - java. Thanks

• When using DrawText, what does TextFormatFlags.Internal (a.k.a. DT_INTERNAL) do?

  - by Daniel Stutzbach

  When using TextRenderer.DrawText(), what does setting the TextFormatFlags.Internal flag actually do? Equivalently, what does setting the DT_INTERNAL flag to Win32's DrawTextEx() function do? More to the point, when should I set that flag and when should I not set it? The documentation says: "Uses the system font to calculate text metrics", but I'm not entirely sure what that means. I've done some limited testing and setting the flag seems to change how the font is rendered when using a small font size, but doesn't seem to make a difference when using a large font size.

• Create Posterous like functionality for my website ?

  - by Rahul

  Well, the problem is i am building a web app which allows users to post on their web page from their email itself . The technically the users are group of people ( its confined to a small team ) who would like to post from time to time about the activity they do ( its regarding the fest of my college). to make it simple for them , i thought it will be better if they just send a mail to [email protected] and that will get posted to their respective web pages created by me . i am a novice php programmer and have no idea on how to proceed on this.

• Effecient data structure design

  - by Sway

  Hi there, I need to match a series of user inputed words against a large dictionary of words (to ensure the entered value exists). So if the user entered: "orange" it should match an entry "orange' in the dictionary. Now the catch is that the user can also enter a wildcard or series of wildcard characters like say "or__ge" which would also match "orange" The key requirements are: * this should be as fast as possible. * use the smallest amount of memory to achieve it. If the size of the word list was small I could use a string containing all the words and use regular expressions. however given that the word list could contain potentially hundreds of thousands of enteries I'm assuming this wouldn't work. So is some sort of 'tree' be the way to go for this...? Any thoughts or suggestions on this would be totally appreciated! Thanks in advance, Matt

• Querying Active Directory in ruby app on Windows box

  - by Ben

  I have a small ruby app in which I'm trying to query some information from Active Directory. The app will be run by a Windows user who is already logged in. It looks like the ruby-net-ldap gem wants me to connect to an LDAP server using an IP address, port and then pass my username and password. Is there a way to achieve this (with a different gem, say) so that I don't have to pass this information (I don't have the current user's password for example, so that's not going to work)? I'm also hosting a Trac website on our intranet (which is written in Python if I remember correctly and that seems to know the current Windows username and domain. If it can do it, surely my little ruby app can access this information too?

• Denormalize for Simplicity: Ungood idea?

  - by yar

  After reading this question, I've learned that denormalization is not a solution for simplicity. What about this case? I have news-articles which have a list of sites-article-will-be-published-to. The latter can be expressed in normalized fashion either by table and a many-to-many relationship (via a cross-table, I think). But the simple solution is to just throw a bunch of booleans for the sites-article-will-be-published-to. Assuming the sites are: small in number will not change over time have no fields themselves, except a name Is this still a terrible idea? The many-to-many relationship seems somewhat cumbersome, but I've done it before in cases like this (and it seemed cumbersome). Note: I'm doing this in Rails, where it's not that painful.

• update table with information from IDirectory

  - by sue

  I have a table with 4 columns, LoginID, LastName, FirstName, Email. The data for LoginID was populated from an other table. I have to write a small routine to update this table, by sending in the LoginID and with help of IDirectory routines, get the Lastname, firstname and email. This is what i'm attempting to do, but getting confused with the right syntax. using (TSADRequestEntities context = UnityHelper.Resolve()) { var fpvalues = context.FOCALPOINTs.ToList(); foreach (var item in fpvalues) { IEnumerable<UserInfo> query = UnityHelper.Resolve<IUserDirectory>().Search(item.LoginID); //Here, FocalPoint is the table that has the loginID and the other fields //I need to update. the query shld now hv info on lastname etc..how do I //retrieve that value and update the table? } }

• Android : How to Remove all capital letters from image filenames before importing into Eclipse

  - by Hubert

  As you know, you can't have capital letters in your image filenames that you use in your Android project (Ressource/Drawables folder). I've got hundreds of small images (GOOG.GIF as an exemple) that I need to import into my project (I usually do a simple drag and drop from a desktop folder into Eclipse). So here's the question : How do I quickly change all the filenames (replace all capital letters to lower case) before importing into my project ? So, GOOG.GIF becomes goog.gif AAPL.GIF becomes aapl.gif etc. Any quick command line solution or another tool to do just that ? Thanks.

• Can I turn off implicit Python unicode conversions to find my mixed-strings bugs?

  - by Tal Weiss

  When profiling our code I was surprised to find millions of calls to C:\Python26\lib\encodings\utf_8.py:15(decode) I started debugging and found that across our code base there are many small bugs, usually comparing a string to a unicode or adding a sting and a unicode. Python graciously decodes the strings and performs the following operations in unicode. How kind. But expensive! I am fluent in unicode, having read Joel Spolsky and Dive Into Python... I try to keep our code internals in unicode only. My question - can I turn off this pythonic nice-guy behavior? At least until I find all these bugs and fix them (usually by adding a u'u')? Some of them are extremely hard to find (a variable that is sometimes a string...). Python 2.6.5 (and I can't switch to 3.x).

• Question about OOP and objects.

  - by loddn

  I have a school assignment, a Dog Show. My assignment is to create a website where vistors can display results and Judges and Secretary can admin, crud. I have a small problem one part of the assignment. The result should be based on two protokols from different judges and after that checked by the secretary before the result is displayed for the user. I have to say i'm fairly new to programming and so i need some smart suggestions on how to design and implement this. The assignment should cover both a db and c# (.net mvc). Q1: How do i create a object (result)that depends on two other objects(protocol)? Is that even needed? Q2: How to solve this in a relational db?

• How do you manage tasks within your work?

  - by Michael

  Just wondering how you all manage your workload effectively when there's a lot of your plate? What do you do to break it down into bite-size chunks and how do you track progress of each task? Do you find TDD helps to focus your attention of getting areas of functionality complete before moving onto the next one? I quite often find myself getting a bit overwhelmed when I have an involving task on the go (even if it can be broken down into lots of small chunks), even though I know I'm more than capable of doing the work. We have a kind of agile approach Interested to hear how everyone manages things effectively.

• How can I make visual studio 2010 deploy (or FTP upload) a page on save?

  - by Isa

  Just started using Visual Studio 2010, moved over from Netbeans. I kinda liked the Netbeans upload on save functionality, which was useful in development environments when one is constantly making small changes and testing them. As soon as you saved a file, it would be synced to the FTP server. Is it possible to do this in VS? I'm pretty sure there is a way, using a macro of some sort, and having it run on every save? However I have no idea how to implement it... Maybe even a keyboard shortcut to deploy the current working file would be nice.

• If don't own proprietary database engine, what is best way to convert database to mysql?

  - by John Robertson

  I work for a very small company. I was recently faced with the question of whether there is a good way to convert a proprietary database to a MySQL database without owning the proprietary database engine e.g. if one is given a large oracle database file (or choose your favorite proprietary database engine format), but doesn't have a license for the oracle database engine, is there a good, perfectly reliable way to convert it to a MySQL database format that can be read with the MySQL database engine? My question is very vague as to which proprietary format is the source just because there would be multiple sources and it looks like they would be "various and sundry". My suspicion is that there is no perfectly reliable way, especially for a wide variety of proprietary databases. If there are a few proprietary formats for which this is possible, I would still be interested in knowing, though "various and sundry" is probably the real issue. Minimizing cost, effort and correct conversion are key so I think this is probably is the not possible list. -John

• Why do people develop emotional attachments for programming languages?

  - by Andrew Heath

  Aside from people who actually developed the languages, I really don't get how someone can develop passion/attachment/perhaps even obsession for a programming language... yet not a day goes by that I don't see a programmer exhibiting this behavior on the internet. I understand how people can feel this way regarding spoken languages - but there's a whole boatload of culture, history, etc that come attached with them. By comparison, the "Python Culture" (as an example) is so small as to be wholly insignificant. Does everyone have a language they love? Am I the odd one out? The dirty polygamist? Are these people rational or silly?

• How to open files in Java Swing without JFileChooser

  - by ron

  I'm using Java Swing (GUI) and I want to add a button to my project for opening files . I don't like the JFileChooser since it opens a small window for browsing through the files of the directories . Can I use something else , instead of the JFileChooser under Java Swing ? I've tried to use elements of SWT but it didn't work , meaning is the use of the button object and then use it inside the Jframe , but that failed , so I guess SWT and Swing don't mix together? Here is the example of Java Swing with JFileChooser and I'm looking for something like this to put in my JFrame.

• Azure flexibility in geolocation and specs

  - by bitbitbit

  Hi, I'm reading about Azure and there are a couple of things I don't understand: If I choose put a server on Europe, why can't I move it to another datacenter afterwards? If I choose a size for a worker/web role, could I upgrade it to a bigger one afterwards? I think I've read that I cannot put different instances of a worker/web role with different sizes working together? Am I right? And in affirmative case, why? What is cheaper? a big VM with a nicely multithreaded worker role or multiple single-threaded worker roles in several small VMs? Thanks in advance.

• How to hide nested form from jQuery under IE8

  - by pduel

  An html segment with a div containing a form: <div class="hide"> Form header <form action='' method='post'> .... form content here </form> form footer </div> <script type="text/javascript"><!--// $(document).ready(function() { $('.hide').hide(); } //--></script> The jquery should hide the form, but does not do so under IE8. (version 8.0.60001) The form content gets hidden, as does the content within the class='hide' div but outside the form, but the form border continues to show, and retains its size. Does anybody have a workaround for this? jQuery is version 1.4.2 I tried to create a small problem demo in jsfiddle, but that site was not functional in the IE browser.
