    - by Yauhen Yakimovich
    Top-like utilities are extremely handful in my work and I want to make sure I am not missing any of them. Please extend the following list of performance monitoring (top-like) family of linux tools: top - original tool htop - adds support to multicore/cpu iotop - input/output monitoring iftop - network monitoring atop - merges previous elements into a single overview slabtop – displays a listing of the top caches ? The only criteria - maturity and similarity in function/style.

  • What would a new web development tool need to succeed?

    - by boost
    If one wanted to bring a new web development tool to market, what would it have to be able to do that would differentiate it enough from all the others to attract people's attention? In what areas are all the other frameworks and languages falling down, such that if a new product addressed those issues, it would stand a chance of being adopted by significant user community?

  • Any suggestions for good automated web load testing tool?

    - by fmunkert
    What are some good automated tools for load testing (stress testing) web applications, that do not use record and replay of HTTP network packets? I am aware that there are numerous load testing tools on the market that record and replay HTTP network packets. But these are unsuitable for my purpose, because of this: The HTTP packet format changes very often in our application (e.g. when we optimize an AJAX call). We do not want to adapt all test scripts just because there is a slight change in HTTP packet format. Our test team shall not need to know any internals about our application to write their test scripts. A tool that replays HTTP packets, however, requires the team to know the format of HTTP requests and responses, such that they can adapt details of the replayed HTTP packets (e.g. user name). The automated load testing tool I am looking for should be able to let the test team write "black box" test scripts such as: Invoke web page at URL http://... . First, enter XXX into text field XXX. Then, press button XXX. Wait until response has been received from web server. Verify that text field XXX now contains the text XXX. The tool should be able to simulate up to several 1000 users, and it should be compatible with web applications using ASP.NET and AJAX.

  • Formatting the output of a custom tool so I can double click an error in Visual Studio and the file opens

    - by Ben Scott
    I've written a command line tool that preprocesses a number of files then compiles them using CodeDom. The tool writes a copyright notice and some progress text to the standard output, then writes any errors from the compilation step using the following format: foreach (var err in results.Errors) { // err is CompilerError var filename = "Path\To\input_file.xprt"; Console.WriteLine(string.Format( "{0} ({1},{2}): {3}{4} ({5})", filename, err.Line, err.Column, err.IsWarning ? "" : "ERROR: ", err.ErrorText, err.ErrorNumber)); } It then writes the number of errors, like "14 errors". This is an example of how the error appears in the console: Path\To\input_file.xrpt (73,28): ERROR: An object reference is required for the non-static field, method, or property 'Some.Object.get' (CS0120) When I run this as a custom tool in VS2008 (by calling it in the post-build event command line of one of my project's assemblies), the errors appear nicely formatted in the Error List, with the correct text in each column. When I roll over the filename the fully qualified path pops up. The line and column are different to the source file because of the preprocessing which is fine. The only thing that stands out is that the Project given in the list is the one that has the post-build event. The problem is that when I double click an error, nothing happens. I would have expected the file to open in the editor. I'm vaugely aware of the Microsoft.VisualStudio.Shell.Interop namespace but I think it should be possible just by writing to the standard output.

  • What are the reasons why the CPU usage doesn’t go 100% with C# and APM?

    - by Martin
    I have an application which is CPU intensive. When the data is processed on a single thread, the CPU usage goes to 100% for many minutes. So the performance of the application appears to be bound by the CPU. I have multithreaded the logic of the application, which result in an increase of the overall performance. However, the CPU usage hardly goes above 30%-50%. I would expect the CPU (and the many cores) to go to 100% since I process many set of data at the same time. Below is a simplified example of the logic I use to start the threads. When I run this example, the CPU goes to 100% (on an 8/16 cores machine). However, my application which uses the same pattern doesn’t. public class DataExecutionContext { public int Counter { get; set; } // Arrays of data } static void Main(string[] args) { // Load data from the database into the context var contexts = new List<DataExecutionContext>(100); for (int i = 0; i < 100; i++) { contexts.Add(new DataExecutionContext()); } // Data loaded. Start to process. var latch = new CountdownEvent(contexts.Count); var processData = new Action<DataExecutionContext>(c => { // The thread doesn't access data from a DB, file, // network, etc. It reads and write data in RAM only // (in its context). for (int i = 0; i < 100000000; i++) c.Counter++; }); foreach (var context in contexts) { processData.BeginInvoke(context, new AsyncCallback(ar => { latch.Signal(); }), null); } latch.Wait(); } I have reduced the number of locks to the strict minimum (only the latch is locking). The best way I found was to create a context in which a thread can read/write in memory. Contexts are not shared among other threads. The threads can’t access the database, files or network. In other words, I profiled my application and I didn’t find any bottleneck. Why the CPU usage of my application doesn’t go about 50%? Is it the pattern I use? Should I create my own thread instead of using the .Net thread pool? Is there any gotchas? Is there any tool that you could recommend me to find my issue? Thanks!

  • How to correctly formalize the command line usage of GNU/Linux commands?

    - by Francesco Turco
    I'd like to write down a BNF-like formal grammar for describing the command line usage of some GNU/Linux tools. For example I can describe the usage of the cat command as: (cat-command) : 'cat' (arguments-list) (arguments-list) : (argument) (arguments-list) : (arguments-list) (argument) (argument) : (file) The problem is I can't write down a precise grammar for some commands such as md5sum. My first attempt at that would be the following: (md5sum-command) : 'md5sum' (arguments-list) (arguments-list) : (argument) (arguments-list) : (arguments-list) (argument) (argument) : (file) (argument) : '--check' But as you can see this grammar allows you to specify the --check argument as many times as you wish, which is incorrect as you should use it at most one time. How can I fix that? Also, what kind of formal grammars I should study for better treating this kind of problems? Thanks.

  • Is Java serialization a tool to shrink the memory footprint?

    - by Pentius
    Hey folks, does serialization in Java always have to shrink the memory that is used to hold an object structure? Or is it likely that serialization will have higher costs? In other words: Is serialization a tool to shrink the memory footprint of object structures in Java? Edit I'm totally aware of what serialization was intended for, but thanks anyway :-) But you know, tools can be misused. My question is, whether it is a good tool to decrease the memory usage. So what reasons can you imagine, why memory usage should increase/decrease? What will happen in most cases?

  • Is there any practical usage of Doubly Linked List, Queues and Stacks?

    - by Chouette
    I've been coding for quite sometime now. And my work pertains to solving real-world business scenarios. However, I have not really come across any practical usage of some of the data structures like the Linked List, Queues and Stacks etc. Not even at the business framework level. Of course, there is the ubiquitous HashTable, ArrayList and of late the List...but is there any practical usage of some of the other basic data structures? It would be great if someone gave a real-world solution where a Doubly Linked List "performs" better than the obvious easily usable counterpart.

  • Is there a Firefox or Chrome plugin, or a standalone program, for monitoring site usage and search queries?

    - by Leigh Caldwell
    I'm running some research on how people search the web for specific types of information. I'd like to be able to set them up with a laptop and browser and then record a history of what they search for and what sites they visit. A Firefox or Chrome plugin would be ideal, but a standalone program is fine too. It doesn't need to be free, just quick and reliable. It doesn't need to be a general PC monitoring program (though that would be OK too) - it's only Web usage I need to track. I've found a few on the Web but am not sure which ones to trust. Your recommendations would be much appreciated.

  • How can I reduce the CPU usage of Offline Files?

    - by Diego
    Whenever I have the Offline Files service running, there is a constant 25% CPU usage on svchost.exe (this is a quad core, so that means it's using up one core). This, in turn, triples the power consumption and keeps the machine hot... I do have several GB synchronized (music collection), but they are not changing at all, in either side. Am I misusing this feature? Is there anything I can configure to keep it down when there's nothing to do? Or should I forget about it and synchronize big folders manually?
