• How to Deploy my Open Source Projects using Maven's Central Repository?

  - by sfussenegger

  Is there anything I could do to get my own open source stuff into Maven's Central repository? I've wondered many times how I could get my own projects into Maven's Central repository. I was asking this myself, especially as I've seen some well known projects hosting their own repository, requiring users to add dependency and repository. At the same time, it's getting difficult for other projects to depend on those projects. As I neither want others to add an additional repository nor to host one myself, I'm looking for other ways. And why aren't some projects using the option to deploy to Maven Central in favor of their self-hosted repository? Any good reasons that aren't obvious?

• Problems adding static library QT project

  - by Smek

  I have problems adding a static library to my Qt project. I have two project one is my static library and the other one is a Qt GUI project. As I add all classes to my GUI project as c++ or header files everything works just fine but I want this to be in a separate library. When I select the option to add a library I check External library then I select the .a file I have build and the folder where my header files can be found because I am working on a Mac I select Mac as the target platform. Then I click continue and then done. macx: LIBS += -L$$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/ -lMyLib INCLUDEPATH += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/include DEPENDPATH += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/include macx: PRE_TARGETDEPS += $$PWD/../../MyLib/build-MyLib-Desktop_Qt_5_2_1_clang_64bit-Debug/libMyLib.a When I build my GUI project I get the following error: The process "/usr/bin/make" exited with code 2. Can anyone tell me what the problem can be and how to resolve the problem? Thanks

• Configurability for windows application built in C#

  - by Sam

  Hi, I am working on a windows application which is developed in C#. I am kinda new in windows world. I want to restrict number of parallel threads running for this application at a given point of time. This number can be changed by user on a beefier machine. What is the best way to do this configuration and how it can be achieved. I can think of following approaches. 1. Use ConfigurationManager to read the configuration value. If user exists more than N number of threads show a message and give option there to modify the value of N. 2. Use registery entry? Thanks in Advance! Sam

• Data model for timesheet to task and/or timesheet to project?

  - by John

  Let's say I want to make a simple project tracking system. A manager can create a project. Then he can create tasks for that project. Team members can record the hours they work for each task or for the project as a whole. Is the following design for the t_timesheet table a good idea? timesheet_id - primary key, autoincrement project_id - not null, foreign key constraint to t_project task_id - nullable, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal Or should I do something like this: timesheet_id - primary key, autoincrement task_id - not null, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal In the second option, I intend to always have a record in t_task labelled "miscellaneous items" with a foreign key to the relevant t_project record. Then I'll be able to track all hours for a project that aren't for any particular task. Are any of the ideas above good? What would be better?

• jQuery Tools - Range Input with Mousewheel support

  - by pspahn

  I've got a nice looking horizontal scroller that uses the Range Input feature of jQ Tools. Mouse wheel scrolling support would be awesome, and I'm sure it can work, just not sure how to get it set up. I've got the generic setup: var scroll = jQuery('#scroll'); jQuery(':range').rangeinput({ speed: 0, progress: true, onSlide: function(ev, step) { scroll.css({left: -step}); }, change: function(e, i) { scroll.animate({left: -i}, "fast"); } }); The doc page ( http://jquerytools.org/documentation/toolbox/mousewheel.html ) for mousewheel gives an example: $("#myelement").mousewheel(function(event, delta) { }); But I'm not sure how this hooks in. Other tools in the package simply allow the option: mousewheel: true Unfortunately that doesn't work on range input. Any advice appreciated. Thank you.

• Using Visual Studio 2005 (32bit) on a Windows 7 64bit machine.

  - by Krakkos

  I need to use Visual Studio 2005 (C++) on my new laptop - a Sony Vaio with Windows 7 64bit.. I don't need to develop for a 64bit environment, my work is all 32bit, so how can I be sure that I can still develop/debug/test for a 32bit target environment using VS2005 on a 64bit machine....? What's the best option: 1) Just install VS2005 on Windows 7 64bit and carry on.. (suspect problems with 64bit runtime libs..?) 2) Dual boot the laptop with Windows XP 32bit. 3) Run some kind of Virtual Machine with Windows XP in it... (I don't have a VM yet, but would look into it) Thanks

• What are the major differences between Windows CE and Windows Mobile for a programmer?

  - by Brad Bruce

  What are the major differences between Windows CE and Windows Mobile for a programmer? I'd love to find a feature table, but haven't been able to find one on the Microsoft web site. I'm starting to work on a project involving industrial handheld terminals. I'm early into the design phase and need to find a comparison of Windows CE and Windows Mobile. Many of the people I'll be talking to jump on the first option that sounds "good enough". I want my first suggestion to be the best based on their needs. We're talking heavy duty hardware with a heavy duty price. I've got to get the programming questions out of the way early. We're currently a MFC6 and .Net 2.0 shop

• GAE uploading to database - or - how to create big dictionary in GAE?

  - by Koran

  Hi, I have a GAE application. A new request is to have a huge database to store many items for some functionality. The database needs to populated every week or so - and populating it is done by querying many external links which overall takes around 1-2 hours. So, doing it via GAE Cron is now out of the question. Another option I was thinking was to create it in external server and then uploading it to GAE DB. Is it possible to upload the data created externally to GAE DB straightaway? The question is because there will be close to 10 M items in it, so adding items individually to a DB is not going to work due to 30 second time limit. Thanks K

• How to retrieve all errors and messages from a query using ADO

  - by Johan Levin

  When a SQL batch returns more than one message from e.g. print statements, then I can only retrieve the first one using the ADO connection's Errors collection. How do I get the rest of the messages? If I run this script: Option Explicit Dim conn Set conn = CreateObject("ADODB.Connection") conn.Provider = "SQLOLEDB" conn.ConnectionString = "Data Source=(local);Integrated Security=SSPI;Initial Catalog=Master" conn.Open conn.Execute("print 'Foo'" & vbCrLf & "print 'Bar'" & vbCrLf & "raiserror ('xyz', 10, 127)") Dim error For Each error in conn.Errors MsgBox error.Description Next Then I only get "Foo" back, never "Bar" or "xyz". Is there a way to get the remaining messages?

• Writing a DTD: How to achieve this children setup

  - by Boldewyn

  The element tasklist may contain at most one title and at most one description, additionally any number (incl. 0) task elements in any order. The naive approach is not applicable, since the order should not matter: <!ELEMENT tasklist (title?, description?, task*) > Alternatively, I could explicitly name all possible options: (title, description?, task*) | (title, task+, description?, task*) | (task+, title, task*, description?, task*) | (description, title?, task*) | (description, task+, title?, task*) | (task+, description, task*, title?, task*) | (task*) but then it's quite easy to write a non-deterministic rule, and furthermore it looks like the direct path to darkest madness. Any ideas, how this could be done more elegantly? And no, an XSD or RelaxNG is no option. I need a plain, old DTD.

• 2 way communication over http between a .Net service and Windows Forms Client

  - by user1802969

  I am looking to accomplish 2 way communication over http between a .Net service (WCF SOAP or REST, both options are open) hosted on IIS 7 and Windows Forms Client running on Windows 7. WebSockets are not supported with IIS 7 and all other Comet techniques allow only the web server to push data to client and not the other way around. The client will be very chatty, and there are thousands of clients, so I want to avoid creating a new HTTP request for each message to the server, though that is the last option. Is there any way to do this ?

• Dynamic resize with MPlayer and PyGTK

  - by alex

  Hi everyone; I've wrote a piece of code in python and pygtk for an embeded mplayer in a gui. I assume I use GtkSocket and the slave mode of mplayer with the -wid option. But I've got an issue, when the size of my GTK window is smaller than my stream, the stream appears to be cropped. And when the size of my window is bigger than my stream, the stream appear centred inside the widget which embed MPlayer. (a gtk.Frame but I've also try with a gtk.DrawingArea) I would like to know how I can get my stream resize dynamically depending on the window's size. I don't want to use Glade or any GUI builder. Thanks in advance for any help, and please excuse my poor english.

• How can I request local pages in the background of an ASP.NET MVC app?

  - by flipdoubt

  My ASP.NET MVC app needs to run a set of tasks at startup and in the background at a regular interval. I have implemented each task as a controller action and listed the app-relative path to the action in the database. I implemented a TaskRunner process that gets the urls from the database and requests each one at a regular interval using WebRequest.Create, but this throws a UriFormatException. I cannot use this answer or any code that plucks values from HttpContext.Current.Request without getting an HttpException with the message "Request is not available in this context". The Request object is not available because my code uses System.Threading.Timer to do background processing, as recommended here. Here are my questions: Is there really no way to make local web requests within an ASP.NET web app? Is there really no way to dynamically ascertain the root path to the web app even using static dependencies in ASP.NET? I was trying to avoid storing the app's root path in the database (as FogBugz does with its "Maintenance Path"), but is this best option?

• How should it work if I want a page to have a theme-roller (more or less like the jQuery themeroller

  - by DanC

  The basic idea is to create a page that gives the user the ability to choose a skin or theme from a menu. When the user selects the desired skin/theme, it should be applied to the page, just like the jquery ui theme roller page. So, to be more precise, what I am trying to know is how to apply dynamically the style to a page - how to load the css and so forth. On the jquery ui theme roller, is there any javascript triggered after the new set of styles is loaded? (for js positioning or sizing?) (The answer may be simple as "just create a new style element and set its src"...) Just to be clear, I don't need the option to let users customize the UI, I want them just to be able to pick from a few pre set styles. Thanks!

• Solaris 10 keyboard problem

  - by Tool

  Im runing Solaris 10 - but im having problems with the keyboard. Instead of - i get /, and instead of y i get z, etc. I tried changing every option in the menu "Keyboard Behaviour". I also tried changing kmdconfig from xorg to xsun, but then the graphics goes all wild and ugly - although the keyboard works fine then. Also cant change resolution in xsun mode. By the way, im runing Solaris from Vmware, but i doubt this has anything to do with this.

• Accepting bank account information in a form

  - by jeffthink

  What security concerns are there when accepting a user's bank account information (account number and routing number) via a form on a page that is using SSL, and posting it back to the server where I then curl off a HTTPS request to send that information to an ACH service like First ACH or ACH Direct via their API? We wouldn't be saving the bank account information in our database. I know another option is to use Paypal's Mass Pay API, but they think it's unprofessional (at least for their business) to require customers to have a paypal account to get paid. Thoughts?

• Using 'Copy as cURL' from Chrome in windows command line

  - by user2029890

  So, Google Chrome as this great 'copy as cURL' option under 'Network' of the Chrome DevTools. Works great in command lines for linux but not in windows. Apparently it has something to do with the single quotes as the error I get is protocol 'http not supported In other words its reading that single quote. Is there a simple way to make this formatable for windows? I tried replacing all the single quotes with double quotes but then nothing happens at all. The command is: curl 'http://www.test.com/login/' -H 'Cookie: PHPSESSID=7dvb25maaaaaa9d7bbbbbc3f6' -H 'Origin: http://www.test.com' -H 'Accept-Encoding: gzip,deflate,sdch' -H 'Host: www.test.com' -H 'Accept-Language: en-US,en;q=0.8' -H 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.95 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8' -H 'Cache-Control: max-age=0' -H 'Referer: http://www.test.com/login/' -H 'Connection: keep-alive' --data 'loc=&login=user%40test.com&password=password&submit1=Sign+In' --compressed Thank you

• Posting Documentation onto a Joomla Site

  - by Chris Spicer

  I would like to create some documentation and post it onto my Joomla website. This documentation would be something along the lines of the MSDN documentation: i.e. each page would follow a basic template. Intuitively I feel I have two ways of achieving this: 1) Creating each page of documentation as a separate article, and then linking them up. 2) Creating some kind of template and filling the information from a database. The second option being preferable in the long run. Unforunately I have no idea how to achieve what I'm looking for. I hoped that there would be a component out there that woud help me, but Googling for 'Joomla Documentation' just brings up the documentation for Joomla itself. Has anyone out there put documentation on their site, and how did they achieve it?

• svn working copy spanning 2 physical drives?

  - by ronenosity

  I have a large repository hosted on dreamhost that I backup daily on a remote machine using a windows scheduled task which updates the working copy located on an external USB 300GB drive connected to the remote machine. The 300GB drive is nearly full with only 26GB of free space remaining. Recently I added a second USB external 1TB drive to increase storage capacity. I would like to ask: what is the best way to use the new 1TB drive? Is it possible to span the working copy across both drives (ex: somehow create a 1.3 TB drive)? If I copied the working copy from the 300GB to the 1TB would svn continue form do I need to retarget the update working copy script to the new 1TB drive and start downloading everything again (least desired option) thanks

• How to get number of rows deleted from mysql in shell script

  - by simonlord

  Hi all I can't work out how to get the mysql client to return the number of rows deleted to the shell when running a delete. Does anyone know what option will enable this? Or ways around it? Here's what i'm trying, but i get no output: #!/bin/bash deleted=`mysql mydb -e "delete from mytable where insertedtime < '2010-04-01 00:00:00'"|tail -n 1` I was expecting something like this as the output from mysql: deleted 999999 Which is why i have the tail -n 1 so i only pick up the count and not the column name. When running the command by hand (mysql mydb -e "delete from mytable where insertedtime < '2010-04-01 00:00:00'") there is no output. When running the command interactively when running the mysql client i ge the following: mysql>delete from mytable where insertedtime < '2010-04-01 00:00:00'; Query OK, 0 rows affected (0.00 sec) I want to get the rows affected count into my shell variable. Any help would be most appreciated.

• C# Importing Large Volume of Data from CSV to Database

  - by guazz

  What's the most efficient method to load large volumes of data from CSV (3 million + rows) to a database. The data needs to be formatted(e.g. name column needs to be split into first name and last name, etc.) I need to do this in a efficiently as possible i.e. time constraints I am siding with the option of reading, transforming and loading the data using a C# application row-by-row? Is this ideal, if not, what are my options? Should I use multithreading?

• Self-Configuring Classes W/ Command Line Args: Pattern or Anti-Pattern?

  - by dsimcha

  I've got a program where a lot of classes have really complicated configuration requirements. I've adopted the pattern of decentralizing the configuration and allowing each class to take and parse the command line/configuration file arguments in its c'tor and do whatever it needs with them. (These are very coarse-grained classes that are only instantiated a few times, so there is absolutely no performance issue here.) This avoids having to do shotgun surgery to plumb new options I add through all the levels they need to be passed through. It also avoids having to specify each configuration option in multiple places (where it's parsed and where it's used). What are some advantages/disadvantages of this style of programming? It seems to reduce separation of concerns in that every class is now doing configuration stuff, and to make programs less self-documenting because what parameters a class takes becomes less explicit. OTOH, it seems to increase encapsulation in that it makes each class more self-contained because no other part of the program needs to know exactly what configuration parameters a class might need.

• Why is passing a string literal into a char* arguament only sometimes a compiler error?

  - by Brian Postow

  I'm working in a C, and C++ program. We used to be compiling without the make-strings-writable option. But that was getting a bunch of warnings, so I turned it off. Then I got a whole bunch of errors of the form "Cannot convert const char* to char* in argmuent 3 of function foo". So, I went through and made a whole lot of changes to fix those. However, today, the program CRASHED because the literal "" was getting passed into a function that was expecting a char*, and was setting the 0th character to 0. It wasn't doing anything bad, just trying to edit a constant, and crashing. My question is, why wasn't that a compiler error? In case it matters, this was on a mac compiled with gcc-4.0.

• Log RuntimeException thrown from thread created by Spring via the @Async annotation

  - by Eugen

  I'm having some difficulty logging RuntimeException from a thread. My system is: Java 7 (b118), Spring 3.0.5. The threads are not created by hand, but via Spring's @Async annotation, which creates it's own executor behind the scenes, so I don't really have the option of overriding any methods of the thread, FutureTask or anything low level. So my question is if Spring has any support or if there are any best practices for handling (logging) these type of exceptions? Any suggestions are appreciated. Thanks.
