  • What is a dedicated Linux box used for?

    - by DanLeaningphp
    So this is probably a very basic and obvious question for most people, but my google-foo is failing me and it just seems something is going over my head. I've heard numerous people refer to having a 'dedicated linux box' as a central part of a developer's setup. I have been doing web-dev programming for about a year and understand the benefits of programming on a Unix/Linux system. But I seem to be missing what role a 'dedicated linux box' plays in the development process. I would assume that it is used as a server of some sort, but I am yet to run across any needs to have a computer dedicated to running a linux server. Am I just being nieve and mistaking the commonality of programmers preferring to work in linux for a tool used by developers? What do most developers use their 'dedicated linux box' for?

  • Hiring a Junior Developer, What should I ask?

    - by Jeremy
    We are currently hiring a junior developer to help me out, as I have more projects than I can currently manage. I have never hired anyone who wasn't a friend or at least an acquaintance. I have a phone interview with the only applicant that actually stood out to me (on paper), but I have never done this before. Our projects are all high scalability, data intensive web applications that process millions of transactions an hour, across multiple servers and clients. To be language/stack specific, we use ASP.Net MVC2, WebForms and C# 4, MSSQL 2008 R2, all running atop Windows Server 2008 R2 What should I ask him? How should I structure the phone call?

  • Will upgrading disrupt online backup software (Crashplan)?

    - by Rob
    Has anyone had any experience upgrading to Ubuntu 11.04, and how this might affect online backup software processes? Specifically, I'm currently running Ubuntu 10.10 and using Crashplan v3. Crashplan backup engine runs constantly in the background to monitor files for changes and back up accordingly. Will upgrading to Ubuntu 11.04 affect any of the Crashplan backup process? Has anyone done this successfully? I'd like to upgrade to the latest and greatest Ubuntu release, but not at the risk of affecting the backup, or worse, having to start from scratch again and upload the entire library!

  • PASS Summit 2013 - A Bunch of Blog Posts Recently

    - by RickHeiges
    Recently, there have been a number of blog posts about having the 2013 PASS Summit in Seattle or elsewhere. I had a post in November about the process and some of the major factors that were on my mind. You can read it here . There is value in moving the Summit to another venue. There is value in having the Summit in the same location/venue year after year as well. Many of the posts that I read recently make excellent arguments for each. As time goes on and you hear another good argument for one...(read more)

  • alsHigh CPU load - Ubuntu 14.04

    - by watt
    I noticed that sometimes when browsing (with other processes in the background), I get very high CPU load for the browser process (over 100%) and the computer becomes really slow. I tried switching from Firefox (with just a few extensions) to Chromium, but same thing happens without me visiting graphics-intense sites, flash sites or anything like that. I also noticed python or node (when running "make") produce the same high CPU load from time to time so this is not necessarily browser-related. When I only have a browser open, it doesn't seem to happen and everything is fine in Windows 7. I switched from unity to gnome3 with no effect. Specs: lenovo w510 (4gb RAM, i7 q820 @ 1.73) + up to date Ubuntu 14.04 64bit. Printscreen: http://imgur.com/8MZJNKC Do you guys have any idea why this might happen? Please let me know if there's other info you need. Thanks!

  • Ubuntu One Bookmark sync not working.

    - by Rob
    Everything in Ubuntu One sync works great except bookmark sync. I tried the wiki answer that said to run: killall beam.smp beam rm ~/.config/desktop-couch/desktop-couchdb.ini dbus-send --session --dest=org.desktopcouch.CouchDB --print-reply --type=method_call / org.desktopcouch.CouchDB.getPort This is what my terminal came back with: robin@robin-MIDWAY:~$ killall beam.smp beam beam: no process found robin@robin-MIDWAY:~$ rm ~/.config/desktop-couch/desktop-couchdb.ini rm: cannot remove `/home/robin/.config/desktop-couch/desktop-couchdb.ini': No such file or directory robin@robin-MIDWAY:~$ dbus-send --session --dest=org.desktopcouch.CouchDB --print-reply --type=method_call / org.desktopcouch.CouchDB.getPort Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. robin@robin-MIDWAY:~$ I'm a computer "newbie" so it's possible I'm doing something wrong, are there any tutorials out there on how to use the CouchDB?

  • It is possible to hibernate an LXC container?

    - by Jo-Erlend Schinstad
    I know about lxc-freeze and lxc-unfreeze, but as I understand it, these simply pauses the container, similar to sending SIGSTOP and SIGCONT to a process. If I reboot the host, then the containers will cease to exist, right? I would really like a way to save state to persistent storage so that I could resume them at some later time, even the host is rebooted or something like that. I can achieve exactly what I want using VirtualBox by using the "Save machine state" mechanism, but if I could do it with LXC, it would be completely awesome.

  • Using GridView and DetailsView in ASP.NET MVC - Part 1

    - by bipinjoshi
    For any beginner in ASP.NET MVC the first disappointment is possibly the lack of any server controls. ASP.NET MVC divides the entire processing logic into three distinct parts namely model, view and controller. In the process views (that represent UI under MVC architecture) need to sacrifice three important features of web forms viz. Postbacks, ViewState and rich event model. Though server controls are not a recommended choice under ASP.NET MVC there are situations where you may need to use server controls. In this two part article I am going to explain, as an example, how GridView and DetailsView can be used in ASP.NET MVC without breaking the MVC pattern.http://www.bipinjoshi.net/articles/59b91531-3fb2-4504-84a4-9f52e2d65c20.aspx

  • Five new junior developers and lots of complex tasks. What's now?

    - by mxe
    Our company has hired five new junior developers to help me to developer our product. Unfortunately the new features and incoming bug fixes usually require deeper knowledge than a recently graduated developer usually has (threading/concurrency, debugging performance bottlenecks in a complex system, etc.) Delegating (and planning) tasks which they (probably) can solve, answering their questions, mentoring/managing them, reviewing their code use up all of my time and I often feel that I could solve the issues less time than the whole delegating process takes (counting only my time). In addition I don't have time to solve the tasks which require deeper system knowledge/more advanced skills and it does not seem that it will change in the near future. So, what's now? What should I do to use their and my time effectively?

  • DNS for domain shows old website for www version

    - by user3745746
    I bought 2 domains form GoDaddy but with both I am seeing the same problems in that the domain on the www version goes to the old site which is still being hosted. I have checked the IntoDNS website and in the www record it shows: Your www.example.com A record is: www.example.com -> example.typepad.com -> cname-cloudflare.typepad.com -> What can I do to stop this from happening? Will this eventually be automatically removed and fix itself? Though obviously it's not automatically fixed itself in the long drawn out expiry process... It's been quite a while for one of them and still hasn't propagated for the www. I'm not having any problems with the normal example.com part of the site.

  • Visual Studio &amp; TFS 11 &ndash; List of extensions and upgrades

    - by terje
    This post is a list of the extensions I recommend for use with Visual Studio 11. It’s coming up all the time – what to install, where are the download sites, last version, etc etc, and thus I thought it better to post it here and keep it updated. The basics are Visual Studio 11 connected to a Team Foundation Server 11. Note that we now are at Beta time, and that also many live in a side-by-side environment with Visual Studio 2010.  The side-by-side is supported by VS 11. However, if you installed a component supporting VS11 before you installed VS11, then you need to reinstall it.  The VSIX installer will understand that it is to apply those only for VS11, and will not touch – nor remove – the same for VS2010. A good example here is the Power Commands. The list is more or less in priority order. The focus is to get a setup which can be used for a complete coding experience for the whole ALM process. The list of course reflects what I use for my work , so it is by no means complete, and for some of the tools there are equally useful alternatives. Many components have not yet arrived with VS11 support.  I will add them as they arrive.  The components directly associated with Visual Studio from Microsoft should be common, see the Microsoft column. If you still need the VS2010 extensions, here they are: The extensions for VS 2010.   Components ready for VS 11, both upgrades and new ones Product Notes Latest Version License Applicable to Microsoft TFS Power Tools Beta 111 Side-by-side with TFS 2010 should work, but remove the Shell Extension from the TFS 2010 power tool first.

Fakes  Was Moles in 2010. Fakes is improved and made into a product.  NuGet Manager Included in the install, but still an extension package. Info here. Product installation, upgrades and patches for VS/TFS 11   Product Notes Date Applicable to Visual Studio 11 & TFS 11 Beta This is the beta release, and you are free to download and try it out. March 2012 Visual Studio and TFS SQL Server 2008 R2 SP1 Cumulative Update 4 The TFS 11 requires the CU1 at least, but you should go up to at least CU4, since this update solves a ghost record problem that otherwise may cause your TFS database to not release records the way it should when you clean it up, see this post for more information on that issue.  Oct 2011 SQL Server 2008 R2 SP1

  • Improve your Application Performance with .NET Framework 4.0

    Nice Article on CodeGuru. This processors we use today are quite different from those of just a few years ago, as most processors today provide multiple cores and/or multiple threads. With multiple cores and/or threads we need to change how we tackle problems in code. Yes we can still continue to write code to perform an action in a top down fashion to complete a task. This apprach will continue to work; however, you are not taking advantage of the extra processing power available. The best way to take advantage of the extra cores prior to .NET Framework 4.0 was to create threads and/or utilize the ThreadPool. For many developers utilizing Threads or the ThreadPool can be a little daunting. The .NET 4.0 Framework drastically simplified the process of utilizing the extra processing power through the Task Parallel Library (TPL). This article talks following topics “Data Parallelism”, “Parallel LINQ (PLINQ)” and “Task Parallelism”. span.fullpost {display:none;}

  • Advantages of Client/Server Architecture over Mainframe Architecture

    Originally mainframe architectures relied on a centralized host server that processed data and returned it to be displayed on a dummy terminal. These dummy terminals did not have my processing power and could only display data that was sent from the mainframe. Application architecture completely changed with the advent of N-Tier architecture. The N-Tier architecture replaced the dummy terminals with standard PCs that could think and/or process for themselves. This allowed for applications to be decentralized. Further, this type of architecture also breaks up the roles found within a mainframe by extracting Web Interfaces, Application Logic and Data access in to 3 separate parts so that it can be extended and distributed as the demands of an application increases.

  • Qt Certification Exams

    - by karlphillip
    I'm wondering about doing a Qt Certification Exam this year, but I'm not 100% sure the investment is worth. I'm considering it because I think it could be a nice + on my resume, and as you know, I'm all for improving my software engineer persona. As I already earn a BSc and MSc degrees in computer stuff, I guess I see the certification process as some kind of adventure. Anyway, I know I'll spend a lot of time preparing myself for the exam and I just wanted to know if a Qt certification is worth the effort. Apparently there are 2 certificates that you can get in the Qt world: Nokia Certified Qt Developer (basic) Nokia Certified Qt Specialist (advanced) Nowadays I build cross-platform software in C++ and this exam would fit beautifully in my resume. My main concern is that, given the obscure future of Qt, I might be throwing time and money out the window. I'm looking for some advice regarding the usefulness of such certifications.
