  • Does Google hire .NET developers? [closed]

    - by Hermann
    I am a .NET developer looking for a job. I've talked to someone who works at Google and loves it there and I generally have a good feeling about working for that company because I love most of Google's products and services. But are they even interested in .NET developers? I had the impression they only use non-proprietary technologies.

  • Creating multiple heads in remote repository

    - by Jab
    We are looking to move our team (~10 developers) from SVN to mercurial. We are trying to figure out how to manage our workflow. In particular, we are trying to see if creating remote heads is the right solution. We currently have a very large repository with multiple, related projects. They share a lot of code, but pieces of the project are deployed by different teams (3 teams) independent of other portions of the code-base. So each team is working on concurrent large features. The way we currently handles this in SVN are branches. Team1 has a branch for Feature1, same deal for the other teams. When Team1 finishes their change, it gets merged into the trunk and deployed out. The other teams follow suite when their project is complete, merging of course. So my initial thought are using Named Branches for these situations. Team1 makes a Feature1 branch off of the default branch in Hg. Now, here is the question. Should the team PUSH that branch, in it's current/half-state to the repository. This will create a second head in the core repo. My initial reaction was "NO!" as it seems like a bad idea. Handling multiple heads on our repository just sounds awful, but there are some advantages... First, the teams want to setup Continuous Integration to build this branch during their development cycle(months long). This will only work if the CI can pull this branch from the repo. This is something we do now with SVN, copy a CI build and change the branch. Easy. Second, it makes it easier for any team member to jump onto the branch and start working. Without pushing to the core repo, they would have to receive a push from a developer on that team with the changeset information. It is also possible to lose local commits to hardware failure. The chances increase a lot if it's a branch by a single developer who has followed the "don't push until finished" approach. And lastly is just for ease of use. The developers can easily just commit and push on their branch at any time without consequence(as they do today, in their SVN branches). Is there a better way to handle this scenario that I may be missing? I just want a veteran's opinion before moving forward with the strategy. For bug fixes we like the general workflow of mecurial, anonymous branches that only consist of 1-2 commits. The simplicity is great for those cases. By the way, I've read this , great article which seems to favor Named branches.

  • How to change CSS color values in real-time off a javascript slider?

    - by bflora
    I'm making a page where the user gets a javascript slider that goes from 0 to 100 and can use it to set the opacity of a div on the page. I want the opacity of that div to change in real-time as they work the slider. I've not done this before. What's the best approach? There cursor in the slider displays the slider's current value as you move it. It seems to be that I just need to find a way to display that value in any arbitrary other place on the page so I can display it in the style settings for the div. The .js file that generates the slider has a line that (I think) is setting the current value in the cursor: $(this).children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); TO get this changing number to display somewhere else at the same time, do I just need to add a div somewhere and then add a line like this? $("#newDivId").children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); That seems like it would give me the number showing up in a div. How then would I get it into a form I could put into the style settings for a div? If this was a php variable, I would do something like this, style="opacity:<?php print $value ?>;" What would be the .js equivalent?

  • Running OpenMPI on Windows XP

    - by iamweird
    Hi there. I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is Z:\orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library.

Does this mean that the problem is in OpenMPI source code itself? Or maybe it's because of wrong/outdated wincred.h and credui.lib I used while building OpenMPI from the source code?

    - by Flint
    I am an ASP.NET developer, but now I want to build a software that can be installed on my PC. Software built in .NET platform only works when the .NET Framework is installed, and software written in Java only works if the JDK is installed. When I install programs like Firefox, uTorrent, etc., I don't need to have any frameworks (.NET, JDK, etc.) installed. How do I write software that doesn't depend on a framework?

  • Open and close trac tickets with a single commit

    - by Jerub
    I am looking for a way to add a post-commit or pre-commit hook to my VCS that will allow me to both create and close a trac ticket in one go. The use-case is for when a bug has been found, and corrected, but a single developer who wants to make sure the project manager can see the fix has been done, when it was done and what milestone the fix has been done in. We have a default milestone in trac when creating a ticket, so reflecting that information would be good too.

  • text-transform cannot change/be overwritten? (css)

    - by Radek
    I am studying css and I do not understand why some OTHER text and line 2 has red underline effect on them. I thought I either changed it for class others or reset it to none for class line2 I tried `text-decoration:none' for both .line2 and .others and the text was still red underlined. <html> <head> <style type="text/css"> .line {color:red; text-transform:uppercase; text-decoration:underline;} .line2 {color:blue; text-transform:none;} .others {color:black; text-transform:lowercase; text-decoration:blink; font-weight:bold;} </style> </head> <body> <div class='line'> line 1 <div class='others'><BR>some OTHER text<BR></DIV> <div class='line2'> <BR>line 2 </div> </div> </body> </html>

    This is a simple question about getting started with developing Android apps using Eclipse. I have followed all the tutorials on the developer site for installing Eclipse, the SDK and the ADT plugin. When trying to run a simple Hello World program, everything seems to compile correctly, but then the virtual machine comes up empty. In the Console Window it reads: The program then just sits and my text never comes up. Any idea with what the problem could be?

  • JVM to ignore certificate name mismatch

    - by Heavy Bytes
    I know there were a lot of questions/answers about how to ignore SSL error in the code. On our dev region dev.domain.tld we have configured a app server over SSL. The certificate that is displayed is for somedev.domain.tld. There is no way to change the certificate, it will always be a domain mismatch. So when I deploy a web-service to https://dev.domain.tld and try to connect/call my webservice I get an exception: Caused by: java.security.cert.CertificateException: No name matching dev.domain.tld found And I have the somedev.domain.tld CERT in my trust store. Now, I saw a lot of samples how to change that in the code (using a Trust Manager that accepts all domains), but how do I specify to the JVM to ignore the domain mismatch when connecting to the server? Is there a -Djavax.net.ssl argument or something? Thank you! UPDATE: Or, since I am using Spring-WS, is there a way to set some property in Spring for that? (WebServiceTemplate) UPDATE I guess I'll have to do use something from Spring Security: http://static.springsource.org/spring-ws/sites/1.5/reference/html/security.html

  • context.Scale() with non-aspect ratio preserving parameters screws effective lineWith

    - by rrenaud
    I am trying to apply some natural transformations whereby the x axis is remapped to some very small domain, like from 0 to 1, whereas y is remapped to some small, but substantially larger domain, like 0 to 30. This way, drawing code can be nice and clean and only care about the model space. However, if I apply a scale, then lines are also scaled, which means that horizontal lines become extremely fat relative to vertical ones. Here is some sample code. When natural_height is much less than natural_height, the picture doesn't look as intended. I want the picture to look like this, which is what happens with a scale that preserves aspect ratio. rftgstats.c om/canvas_good.png However, with a non-aspect ratio preserving scale, the results look like this. rftgstats.c om/canvas_bad.png <html><head><title>Busted example</title></head> <body> <canvas id=example height=300 width=300> <script> var canvas = document.getElementById('example'); var ctx = canvas.getContext('2d'); var natural_width = 10; var natural_height = 50; ctx.scale(canvas.width / natural_width, canvas.height / natural_height); var numLines = 20; ctx.beginPath(); for (var i = 0; i < numLines; ++i) { ctx.moveTo(natural_width / 2, natural_height / 2); var angle = 2 * Math.PI * i / numLines; // yay for screen size independent draw calls. ctx.lineTo(natural_width / 2 + natural_width * Math.cos(angle), natural_height / 2 + natural_height * Math.sin(angle)); } ctx.stroke(); ctx.closePath(); </script> </body> </html>

  • How do I resize an iframe with dynamic content?

    Why do browser vendors make their own css properties, even they know these will not pass the w3c validation? What is the purpose? Is for their own testing, or for web developers, or to demonstrate browser capabilities to the world and to the W3C organizations and to CSS development team of W3C? is it like a beta version of demonstration? if i use any browser specific for now can they remove that property's support from future versions.will i have to edit my css in future For example: https://developer.mozilla.org/en/CSS_Reference/Mozilla_Extensions
