• Automake: How add a building step?

  - by gege2061

  Hello, Currently, I have a build chain, completly manage by automake, like: .vala > .c > .o > .exe I would like add a new step for preprocess a XML file .ui into a vala source: .ui > .vala > .c > .o > .exe I did this, in makefile.am gtkbuilder2vala_SOURCES = \ abstract-window.ui \ main.vala \ $(NULL) And: XSLTPROC = xsltproc .ui.vala: $(XSLTPROC) ... But make don't understand: make: *** No rule to make target `abstract-window.c', needed by `gtkbuilder2vala-abstract-window.o'. Stop. This seems to be a limitation of make: http://www.ensta.fr/~diam/dev/online/autoconf/autobook/autobook_180.html if the translation takes three steps--from .m' to.x', then from .x' to.c', and finally to `.o'---then Automake's simplistic approach will break. Have you another idea?

• Finding App Id under .ipa or .app

  - by Rafael Oliveira

  I'm building an application that search and recognizes any iPhone apps that user has in his/her computer. I would like to know a way to "extract" the id of the application from the .ipa file. I was trying to do the recognition using only the App File Name, but I discovered that the File Name is not the name of the app in Apple Store. Live Poker 6K Free by Zynga != Live Poker 3.7.ipa The id i'm talking about is the app id, like in, http://itunes.apple.com/app/live-poker-6k-free-by-zynga/id354901953?mt=8 the id is 354901953. Does any body has a clue how can I manage to find this information?

• How to create an Intellij and Eclipse compatible code style and code formatting configuration (for j

  - by user141634

  Few weeks ago I tried Intellij and I found it really awesome. Now, at my project there's two programmers (including me) using Intellij and few other programmers gonna still be using Eclipse. Since this project is already very large and it gonna be growing a lot, we need to use compatible Code Style and Code Formatting between Intellij and Eclipse. We do not want to have problems when one user edit one file and reformat it before save. With Eclipse "alone" we used to have some exported configuration, and before anybody starts to work, the first step is just to import this configuration. We already tried to use External Code Formatter, but it didn't work on Intellij 9. So, I have a bunch of questions here: 1 - Is there any way to import eclipse formatting configuration on Intellij 9? 2 - Anybody could share their experience managing this kind of situation? Do you guys have any other suggestion to manage this situation?

• ASP.NET FormsAuthentication Cookie Problem

  - by Niels Bosma

  We use FormAuthentication to manage logins and I have a case where a customer complains where he can login from one computer but to from another. I can see in my logs that his authentican is successfull but he gets bumped back to the login page. I can reproduce the symptons by disabling cookies so I asked the customer to test if cookies are enabled on http://www.tempesttech.com/cookies/cookietest1.asp, but this came out positive. What have I missed? Is there any antivirus/security software that can mess up (ASP.NET) cookies? The user is using IE7 and claims to have F-secure installed.

  - by rick moss

  hi all I have a ruby / rails application that integrates in and outgoing email directly into the app. The app is going to be running on multiple domains each with posible many users sending and recieving email.

• Terminal services and memory limits

  - by Mark Wassell

  Is there a way in Terminal Services to set limits on memory related parameters for a process. For example working set size and, possibly, if it makes sense, total virtual memory allocation for the session? To turn the question around, we have an application which cannot allocate as much virtual memory running on a terminal server as it can when running on a desktop PC (both I would expect to have a limit of 2GB for user mode address space) and I was wondering if there is another limit for processes or users on a terminal server. Perhaps even 2GB per user rather than per process.

• How can let Qt Graphics View Framework support custom layers

  - by jnblue

  Qt's graphics view frameworks is very powerful, but I have not found a way to support custom layers. In Qt, there is a QGraphicsScene::ItemLayer,but QGraphicsScene renders all items are in this layer. I want manage the items with several layers, Just like Illustrator and CorelDraw. all the item only in the current layer will receive the event, be selected or get the key focus etc.. Other layers(not current layer) will not receive all scene event. The most reasons of using layers is I could catalogue a large number of items more clearly.And without needing transfer events to all the layers' items ,I think the graphics frameworks will be more efficient. The last question, does QGraphicsView support rendering server stacked graphics scenes at the same time? If support, I think the "custom layers" can be solved in this way. Thanks very much!

• Azure, SLAs and CAP theorem

  - by dayscott

  Azure itself is imo PaaS and not IaaS. Do you agree? MS gurantees an availability of 99% and a strong consistency. You can find MS SLAs here: http://www.microsoft.com/windowsazure/sla (three SLAs Uptime: http://img229.imageshack.us/img229/4889/unbenanntqt.png ) I can't find anyhing about how they are going to archive that. Do they do backups? If Yes: How do they manage consistency? According to the Cap theorem (http://camelcase.blogspot.com/2007/08/cap-theorem.html ) their claims are not realistic. 2.1 Do you know detailed technical stuff about the how they are going to realize the claims about consistency and availability? On the MS page you'll find three SLAs .docs, one for SQL Azure, the second for Azure AppFabric/.Net Services and the third for Azure Compute&Storage.(Screenshot in 1.) How can one track whether SLAs are violated? Do they offer some sort of monitor, so I don't have to measure the uptime by myself?

  I would like to catch the error and show the appropriate message if the ajax request fails. My code is like the following, but I could not manage to catch the failure ajax request. function getAjaxData(id) { $.post("status.ajax.php", {deviceId : id}, function(data){ var tab1; if (data.length>0) { tab1 = data; } else { tab1 = "Error in Ajax"; } return tab1; }); } I found out that, "Error in Ajax" is never executed when the Ajax request failed. How to handle the ajax error and show the appropriate message if it fails? Thanks very much.

• process thread scheduling

  - by arvind

  I have the following query regarding the scheduling of process threads. a) If my process A has 3 threads then can these threads be scheduled concurrently on the different CPUs in SMP m/c or they will be given time slice on the same cpu. b) Suppose I have two processes A with 3 threads and Process B with 2 threads (all threads are of same priority) then cpu time allocated to each thread (time slice) is dependent on the number of threads in the process or not? Correct me if I am wrong is it so that cpu time is allocated to process which is then shared among its threads i.e. time slice given to process A threads is less than that of Process B threads.

• Creating an Equation Editor 3.0 equation in a Word 2003 document using a marco (or through the API)

  - by Sambatyon

  I think the title is fully descriptive now. Anyway, I need to generate a word document from my delphi application. It needs to choose from one of four different equations (with some specific parameters for each document). So far I have manage to create the whole document programmatically except the equation. Is it possible to create equations programmatically? if so, where is de API documentation from MS? if not, which solution can be used?

• MPI signal handling

  - by Seth Johnson

  When using mpirun, is it possible to catch signals (for example, the SIGINT generated by ^C) in the code being run? For example, I'm running a parallelized python code. I can except KeyboardInterrupt to catch those errors when running python blah.py by itself, but I can't when doing mpirun -np 1 python blah.py. Does anyone have a suggestion? Even finding how to catch signals in a C or C++ compiled program would be a helpful start. If I send a signal to the spawned Python processes, they can handle the signals properly; however, signals sent to the parent orterun process (i.e. from exceeding wall time on a cluster, or pressing control-C in a terminal) will kill everything immediately.

• Developing Android applications with Visual Studio 2008

  - by Goz

  Hi all, I've recently obtained an HTC Desire and I'm interested in porting my 3D engine to the device. I have a slight annoyance however. I'd love to be able to do development under Visual Studio 2008. Am I to assume I'm going to need to re-process my SLN files to do GCC builds? Its not a vast issue as I already have an application that processes SLN and VCProj files through GCC and then links them together at the other end. I'll just need to set up the right libraries with it. Are there any other gotchas I need to think about? Or, indeed, is there an easier way? Any info would be much appreciated! Cheers :)

• Handling database failover for Rails applications on FreeBSD

  - by bianster

  I'm working on implementing database (Postgresql) failover for a Rails app that runs with Passenger/FreeBSD. Due to certain constraints regarding the server OS, it's necessary to continue using FreeBSD (as opposed to say, Ubuntu). I'm finding it to be quite a challenge to have failover handled within the Rails application, by way of a customised database adapter due to the fact that this application will be load-balanced between several webservers, and the multiple Rails processes that Passenger spawned in each webserver. I previously looked at setting up Pacemaker/Corosync to manage database server failover on a common IP but unfortunately I wasn't able to get past building the packages on FreeBSD. It does work rather well on Ubuntu 10.04 but I'm not likely to be able to use Ubuntu due to the OS constraints. I'm considering a custom witness daemon that simply pings the primary DB server, and this witness daemon switches all the webservers to the standby DB server when the primary becomes uncontactable (permanently/temporarily), to avoid split-brain. Though I would really like to know if there is a way to get Pacemaker(or something similar) to do the switch on FreeBSD.

• Code reviews for larger MVC.NET team using TFS

  - by Parrots

  I'm trying to find a good code review workflow for my team. Most questions similar to this on SO revolve around using shelved changes for the review, however I'm curious about how this works for people with larger teams. We usually have 2-3 people working a story (UI person, Domain/Repository person, sometimes DB person). I've recommended the shelf idea but we're all concerned about how to manage that with multiple people working the same feature. How could you share a shelf between multiple programmers at that point? We worry it would be clunky and we might easily have unintended consequences moving to this workflow. Of course moving to shelfs for each feature avoids having 10 or so checkins per feature (as developers need to share code) making seeing the diffs at code review time painful. Has anyone else been able to successfully deal with this? Are there any tools out there people have found useful aside from shelfs in TFS (preferably open-source)?

• ETW tracking from .net, user mode and driver

  - by Jack Juiceson

  Hi everyone, We have an application that parts of it are in .net, c++ usermode and C++ drivers. The application is divided into several executables that run on demand and communication with each other using LPC(the processes run in different sessions(winlogon)). Currently We have a home written logging service to which .net and c++ usermode communicate by sending LPC messages. The driver uses DbgPrint and is not always enabled, as it causes the code to run 30% slower(we have lots of logging). I want to have all the logs written in one place and preferably not writing the logger myself(I love log4cpp and log4net). The requirement is to write from all the executables and drivers into one place and to have minimal overhead. I have read that ETW is way to go, however I wasn't able to find already written logger that uses it like log4cpp or log4net. So basically my questions is, do you know if there is already implemented ETW appender for log4cpp and log4net I can use ?

• Issue with jQuery ajax post (working with get). error 12031

  - by jul

  hi, UPDATE: I didn't set the response mimetype to 'application/json'. It works now. In the website I'm working on (http://piem.org:8000/) I've got an issue with an ajax post request. Every time the search button is clicked or the google maps 'idle' is triggered I send a request to get some data. While the request works as expected in most cases, it returns an error when I click a result and come back to the search page. (type 'barcelona' in the search box to get the unique restaurant in the db). The server processes the request properly but it seems that the error occurs when the javascript receives it (it returns a "12031" error code). It works properly with FF 3.0.6, IE 8.0 and Chrome 5.0 with GET, and with FF with both POST and GET. Anybody can help? thanks jul

• Is there a way to make sure a background process spawned by my program is killed when my process ter

  - by Davy8

  Basically the child process runs indefinitely until killed in the background, and I want to clean it up when my program terminates for any reason, i.e. via the Taskmanager. Currently I have a while (Process.GetProcessesByName("ParentProcess").Count() 0) loop and exit if the parent process isn't running, but it seems pretty brittle, and if I wanted it to work under debugger in Visual Studio I'd have to add "ParentProcess.vshost" or something. Is there any way to make sure that the child process end without requiring the child process to know about the parent process? I'd prefer a solution in managed code, but if there isn't one I can PInvoke. Edit: Passing the PID seems like a more robust solution, but for curiosity's sake, what if the child process was not my code but some exe that I have no control over? Is there a way to safeguard against possibly creating orphaned child processes?

• How to transform phrases and words into MD5 hash?

  - by brilliant

  Can anyone, please, explain to me how to transform a phrase like "I want to buy some milk" into MD5? I read Wikipedia article on MD5, but the explanation given there is beyond my comprehension: "MD5 processes a variable-length message into a fixed-length output of 128 bits. The input message is broken up into chunks of 512-bit blocks (sixteen 32-bit little endian integers)" "sixteen 32-bit little endian integers" is already hard for me. I checked the article on little endians and didn't understand a bit. However, the examples of some phrases and their MD5 hashes are very nice: MD5("The quick brown fox jumps over the lazy dog") = 9e107d9d372bb6826bd81d3542a419d6 MD5("The quick brown fox jumps over the lazy dog.") = e4d909c290d0fb1ca068ffaddf22cbd0 Can anyone, please, explain to me how this MD5 algorithm works on some very simple example? And also, perhaps you know some software or a code that would transform phrases into their MD5. If yes, please, let me know.

• How do you keep a balance between working, training, health and family?

  - by Jim Burger

  One trend I see in the awesome developers I've met, is that they devote inordinate amounts of time to coding at the expense of (usually) their health. Personally, I also find it hard to motivate myself to keep healthy. Every now and again, I meet a fantastic coder who has it clocked; they are up to date with the latest dev news, have time to read about good programming practices, and to finish it off, have happy wives/husbands and families. How do you guys/gals manage it in the short 24 hours a day that we all have?

• Python web server

  - by Ben

  Hi I'd like to get suggestions on the best way to serve python scripts up as web pages. Typically I'd like a way for me and my colleagues to write simple web pages with minimal effort ie we focus on the business logic eg creating simple forms etc. Possibly with some way to manage sessions but this is a nice-to-have. It doesn't have to be WYSIWYG as they are developers but we are busy and don't want to spend long turning an idea into reality. It's for internal use so appearances are not paramount. The software required to enable this should be easy to setup and configure. eg adding new directories and python lib dirs should be easy. My first instinct is apache or tomcat with mod_python. Any comments / suggestions welcome. Thanks in advance.
