  • Unintentional run-in with C# thread concurrency

    - by geekrutherford
    For the first time today we began conducting load testing on a ASP.NET application already in production. Obviously you would normally want to load test prior to releasing to a production environment, but that isn't the point here.   We ran a test which simulated 5 users hitting the application doing the same actions simultaneously. The first few pages visited seemed fine and then things just hung for a while before the test failed. While the test was running I was viewing the performance counters on the server noting that the CPU was consistently pegged at 100% until the testing tool gave up.   Fortunately the application logs all exceptions including those unhandled to the database (thanks to log4net). I checked the log and low and behold the error was:   System.ArgumentException: An item with the same key has already been added. (The rest of the stack trace intentionally omitted)   Since the code was running with debug on the line number where the exception occured was also provided. I began inspecting the code and almost immediately it hit me, the section of code responsible for the exception is trying to initialize a static class. My next question was how is this code being hit multiple times when I have a rudimentary check already in place to prevent this kind of thing (i.e. a check on a public variable of the static class before entering the initializing routine). The answer...the check fails because the value is not set before other threads have already made it through.   Not being one who consistently works with threading I wasn't quite sure how to handle this problem. Fortunately a co-worker recalled having to lock a section of code in the past but couldn't recall exactly how. After a quick search on Google the solution is as follows:   Object objLock = new Object(); lock(objLock) { //logic requiring lock }   The lock statement takes an object and tells the .NET runtime that the current thread has exclusive access while the code within brackets is executing. Once the code completes, the lock is released for another thread to utilize.   In my case, I only need to execute the inner code once to initialize my static class. So within the brackets I have a check on a public variable to prevent it from being initialized again.

  • Insanity&ndash;Day 1

    - by D'Arcy Lussier
    Some people do those posts about “Here’s what I’m going to do to change my life”. I don’t really like those. I’m a “don’t tell me what you’re going to do, tell me what you’re doing/have done” type of guy. So while I could say how I’m going to change my life and be healthier and happier and thinner in 60 days, I’m just going to tell you how I’m progressing through the Insanity workout. Insanity is a workout-in-a-box. It’s a collection of DVDs that you work out to. Nothing new here, except that the program is intense. It’s core tenet of the program is intensity – you workout at an elevated heart rate for 3 minutes with a short break in between, as opposed to traditional interval training where you go hard for a short time and recover for a few minutes. The other aspect of it is commitment. There is a timetable to follow – you workout 6 days a week with one rest day. This isn’t meant to be a “pick it up whenever you feel like it” type of program. The videos themselves are kind of…I don’t want to say low quality, but not as polished as I expected. Maybe that’s what they were going for. By that I mean they show shots of cameramen and the production equipment during the workout. Otherwise, it’s the Insanity leader Shawn T. leading a group of pretty fit folks through this gruelling workout. And ultimately, those little production nit-picks are irrelevant compared to the actual workout. Holy crap. I haven’t done an aerobics class in like…ever. And watching the video before my actual workout, I thought “That doesn’t look too hard”. Believe me, it is. No weights, no machines, just various exercises done in circuits and with increasing speed. By the end of the workout, I was drenched. So that was day one. Some stats just so I can track it: I’m 286 lbs at my last weigh-in a week ago or so. Should be interesting to see what 60 days of this does! D

  • Reliable Storage Systems for SQL Server

    By validating the IO path before commissioning the production database system, and performing ongoing validation through page checksums and DBCC checks, you can hopefully avoid data corruption altogether, or at least nip it in the bud. If corruption occurs, then you have to take the right decisions fast to deal with it. Rod Colledge explains how a pessimistic mindset can be an advantage

  • Do you use unit tests at work? What benefits do you get from them?

    - by Anonymous
    I had planned to study and apply unit testing to my code, but after talking with my colleagues, some of them suggested to me that it's not necessary and it has a very little benefit. They also claim that only a few companies actually do unit testing with production software. I am curious how people have applied unit testing at work and what benefits they are getting from using them, e.g., better code quality, reduced development time in the long term, etc.

  • Landscape-like tool to distribute security upgrades to OS?

    - by Ichikata
    i'm looking for an alternative to Landscape, Spacewalk (for RHEL), or CTL to perform a specific job. I need to control and apply OS upgrades on ubuntu systems, for 100+ servers, and so far i wasn't that lucky. I've tried Approx tool (similar to apt-proxy), but it just caches the content, and what i really need to do is set update milestones, apply the upgrades to QA servers, validate, then Stage environment, and so on to Production. I hope I was clear enough, any answer will be much appreciated.

  • Is my work on a developers test being taken advantage of?

    - by CodeWarrior
    I am looking for a job and have applied to a number of positions. One of them responded, I had a pretty lengthy phone interview (perhaps an hour +) and they then set me up with the developers test. I was told that this test is estimated to take between 6 and 8 hours and that, provided it met with their approval, I could be paid for my work on it. That gave me some pause, but I endeavored. The dev test took place on a VM accessed via RDP. The task was to implement a search page in a web project that requests data from the server, displays it on the screen in a table, has a pretty complicated search filtering scheme (there are about 15 statuses and when sending the search to the server you can search by these statuses) in addition to the string/field search. They want some SVG icons to change color on certain data values, they want some data to be represented differently than how it is in the database, etc. Loooong story short, this took one heck of a lot longer than 6-8 hours. Much of it was due to the very poor VM that I was running on (Visual Studio 2013 took 10 minutes to load, and another 15 minutes to open the 3 GB ginormous solution). After completing, I was told to commit my changes to source control... Hmm, OK. I get an email back that they thought that the SVGs could have their color changed differently, they found a bug in this edge-case, there was an occasional problem with this other thing that I never experienced, etc. So I am 13-14 hours into this thing now and I have to do bug fixes. I do them, and they come back with some more. This is all apparently going into a production application. I noticed some anomalies in the code that was already in there where it looked like other people had coded all of one functionality and not anything else that I could find. Am I just being used for cheap labor? Even if they pay me the promised 50 dollars and hour for 6 hours, I have committed like 18 hours to this thing now. If I bug fix all of the stuff they keep coming up with, I will have worked at least 16 hours for free. I have taken a number of dev tests. I have never taken one where I worked on code that was destined for production. I have never taken one where I implemented a feature that was in the pipeline for development (it was planned for, and I implemented it through the course of the test). And I have never taken one that took 4 rounds and a total of 20+ hours. I get the impression that they are using their dev test to field some of the functionality, that they don't have time for in their normal team, on the cheap. Also, I wouldn't mind a 'devtest' tag.

  • Should I use the ATI proprietary or free drivers with two Crossfire HD5850s?

    - by Dekel
    I own 2 XFX Radeon HD 5850 in crossfire configuration connected to 3 24" monitors. I really want to make Ubuntu my daily OS but can't seem to find the best configuration to use. Some threads say that the free driver is better then the ATI one and some say the new Catalyst fully takes advantage of the card capabilities. Anyone out there with a similar setup? What are your recommendations for a good production in 12.04 setup?

  • On The Question Of Automated Website Testing

    Almost all webmasters (or at least "quite a lot of webmasters") have heard about the significance of website testing before the production. Having developed a website or a web application, most authors want to publish it immediately and see how people like it. If they ignore prior website testing, the project may appear unprepared for real Internet activity and reveal awful performance.
