  • JRockit R28 "Ropsten" released

    - by tomas.nilsson
    R28 is a major release (as indicated by the careless omissions of "minor" and "revision" numbers. The formal name would be R28.0.0). Our customers expect grand new features and innovation from major releases, and "Ropsten" will not disappoint. One of the biggest challenges for IT systems is after the fact diagnostics. That is - Once something has gone wrong, the act of trying to figure out why it went wrong. Monitoring a system and keeping track of system health once it is running is considered a hard problem (one that we to some extent help our customers solve already with JRockit Mission Control), but doing it after something occurred is close to impossible. The most common solution is to set up heavy logging (and sacrificing system performance to do the logging) and hope that the problem occurs again. No one really thinks that this is a good solution, but it's the best there is. Until now. Inspired by the "Black box" in airplanes, JRockit R28 introduces the Flight Recorder. Flight Recorder can be seen as an extremely detailed log, but one that is always on and that comes without a cost to system performance. With JRockit Flight Recorder the customer will be able to get diagnostics information about what happened _before_ a problem occurred, instead of trying to guess by looking at the fallout. Keywords that are important to the customer are: • Extremely detailed, always on, diagnostics information • No performance overhead • Powerful tooling to visualize the data recorded. • Enables diagnostics of bugs and SLA breaches after the fact. For followers of JRockit, other additions are: • New JMX agent that allows JRMC to be used through firewalls more easily • Option to generate HPROF dumps, compatible with tools like Eclipse MAT • Up to 64 BG compressed references (previously 4) • View memory allocation on a thread level (as an Mbean and in Mission Control) • Native memory tracking (Command line and Mbean) • More robust optimizer. • Dropping support for Java 1.4.2 and Itanium If you have any further questions, please email [email protected]. The release can be downloaded from http://www.oracle.com/technology/software/products/jrockit/index.html

  • Can I show a single country (masked out) in GoogleMaps?

    - by NIclas Lindbegr
    Hello! Is it possible to mask away neighbor countries in GoogleMap? In my case I just want to show Sweden on one view. On a second view just Norway, Denmark etc etc... I know it is possible to draw polygon lines and fill them accordingly on to Maps API. Problem is that or the result sets get huge or the lines get very rough etc... Would be nice if GoogleMaps could deliver a country at the time without neighbors. Does anyone know about a good coordinate database with country borders? Best best regards, Niclas

  • Class Loading Deadlocks

    - by tomas.nilsson
    Mattis follows up on his previous post with one more expose on Class Loading Deadlocks As I wrote in a previous post, the class loading mechanism in Java is very powerful. There are many advanced techniques you can use, and when used wrongly you can get into all sorts of trouble. But one of the sneakiest deadlocks you can run into when it comes to class loading doesn't require any home made class loaders or anything. All you need is classes depending on each other, and some bad luck. First of all, here are some basic facts about class loading: 1) If a thread needs to use a class that is not yet loaded, it will try to load that class 2) If another thread is already loading the class, the first thread will wait for the other thread to finish the loading 3) During the loading of a class, one thing that happens is that the <clinit method of a class is being run 4) The <clinit method initializes all static fields, and runs any static blocks in the class. Take the following class for example: class Foo { static Bar bar = new Bar(); static { System.out.println("Loading Foo"); } } The first time a thread needs to use the Foo class, the class will be initialized. The <clinit method will run, creating a new Bar object and printing "Loading Foo" But what happens if the Bar object has never been used before either? Well, then we will need to load that class as well, calling the Bar <clinit method as we go. Can you start to see the potential problem here? A hint is in fact #2 above. What if another thread is currently loading class Bar? The thread loading class Foo will have to wait for that thread to finish loading. But what happens if the <clinit method of class Bar tries to initialize a Foo object? That thread will have to wait for the first thread, and there we have the deadlock. Thread one is waiting for thread two to initialize class Bar, thread two is waiting for thread one to initialize class Foo. All that is needed for a class loading deadlock is static cross dependencies between two classes (and a multi threaded environment): class Foo { static Bar b = new Bar(); } class Bar { static Foo f = new Foo(); } If two threads cause these classes to be loaded at exactly the same time, we will have a deadlock. So, how do you avoid this? Well, one way is of course to not have these circular (static) dependencies. On the other hand, it can be very hard to detect these, and sometimes your design may depend on it. What you can do in that case is to make sure that the classes are first loaded single threadedly, for example during an initialization phase of your application. The following program shows this kind of deadlock. To help bad luck on the way, I added a one second sleep in the static block of the classes to trigger the unlucky timing. Notice that if you uncomment the "//Foo f = new Foo();" line in the main method, the class will be loaded single threadedly, and the program will terminate as it should. public class ClassLoadingDeadlock { // Start two threads. The first will instansiate a Foo object, // the second one will instansiate a Bar object. public static void main(String[] arg) { // Uncomment next line to stop the deadlock // Foo f = new Foo(); new Thread(new FooUser()).start(); new Thread(new BarUser()).start(); } } class FooUser implements Runnable { public void run() { System.out.println("FooUser causing class Foo to be loaded"); Foo f = new Foo(); System.out.println("FooUser done"); } } class BarUser implements Runnable { public void run() { System.out.println("BarUser causing class Bar to be loaded"); Bar b = new Bar(); System.out.println("BarUser done"); } } class Foo { static { // We are deadlock prone even without this sleep... // The sleep just makes us more deterministic try { Thread.sleep(1000); } catch(InterruptedException e) {} } static Bar b = new Bar(); } class Bar { static { try { Thread.sleep(1000); } catch(InterruptedException e) {} } static Foo f = new Foo(); }

  • GLIBC_2.8 not found

    - by Thomas Nilsson
    As a newbie I seem to have messed up my upgrade leaving my system in a very unstable state. I attempted an upgrade from 8.04LTS which ended in an error about libc and kernel upgrades. I tried to upgrade the kernel but am now unsure if that worked, because when I retried my dist-upgrade there was a lot of errors about pre-dependencies and leaving packages un-configured. Now I have a system that answers almost every command with: /lib/libc.so.6: version `GLIBC_2.8' not found (required by /lib/libselinux.so.1) I probably should try a complete re-installation, but I'm investigating if there is any possibility of getting a working glibc so that I at least can have some commands working to ensure that my backups are recent etc. before doing the clean install. not even 'ls' works without saying "glibc_2.8 not found".

  • HAProxy NGInx SSL setup

    - by Niclas
    I've been looking around different setups for a server cluster supporting SSL and I would like to benchmark my idea with you. Requirements: All servers in the cluster should be under the same full domain name. (http and https) Routing to subsystems is done on URI matching in HA proxy. All URIs have support for SSL support. Wish: Centralizing routing rules ---<----http-----<-- | | Inet -->HA--+---https--->NGInx_SSL_1..N | | +---http---> Apache_1..M | +---http---> NodeJS Idea: Configure HA to route all SSL traffic (mode=tcp,algorithm=Source) to an NGInx cluster turning https traffic into http. Re-pass the http traffic from NGInx to the HA for normal load-balancing which performs load balancing based on HA config. My question is simply: Is this the best way to to configure based on requirements above?

  • Forwarding emails to nonexisting users/aliases to external mail server

    - by Niclas Lindqvist
    I'm in the works of installing a postfix mailserver on a machine currently being used as web server. As of right now, I've got it working as far as that I can send and receive emails using telnet through port 25. However, as my customer is concerned with downtime, I'd like to setup all the accounts one by one over time, and making sure it works, rather than just cutting the cord to the old mail server and start creating new accounts on the new system. How can I add the domain customer.com to my mail server and just add something like [email protected] to the users and aliases-lists without the web server trying to send all emails with the @customer.com domain to the new mail server? I'm running ubuntu, using postfix and postfix-mysql on the new machine, the old mail server is on a hosted environment somewhere else, where I don't have any control.

  • Updating AFP version on Windows Server 2003

    - by Niclas Lindqvist
    Hi, We have a couple of Macs, running Leopard and Snow Leopard in our otherwise pure Windows environment. We cannot get file names longer than 31 characters and some times the file permissions gets scrabbled (users can't delete their own folders or access files they usually access). This only occurs when connecting through AFP, We've tried with SMB but it's horribly slow when working with larger documents, so it's not an option. I somewhere read about AFP 3.0 being the answer. So my question is: Is there some way of updating my "AFP version" on Windows Server 2003, or does anyone have a different idea of what might help to resolve this situation?

  • Learn Domain-Driven Design

    - by Ben Griswold
    I just wrote about how I like to present on unfamiliar topics. With this said, Domain-Driven Design (DDD) is no exception. This is yet another area I knew enough about to be dangerous but I certainly was no expert.  As it turns out, researching this topic wasn’t easy. I could be wrong, but it is as if DDD is a secret to which few are privy. If you search the Interwebs, you will likely find little information about DDD until you start rolling over rocks to find that one great write-up, a handful of podcasts and videos and the Readers’ Digest version of the Blue Book which apparently you must read if you really want to get the complete, unabridged skinny on DDD.  Even Wikipedia’s write-up is skimpy which I didn’t know was possible…   Here’s a list of valuable resources.  If you, too, are interested in DDD, this is a good starting place.  Domain-Driven Design: Tackling Complexity in the Heart of Software by Eric Evans Domain-Driven Design Quickly, by Abel Avram & Floyd Marinescu An Introduction to Domain-Driven Design by David Laribee Talking Domain-Driven Design with David Laribee Part 1, Deep Fried Bytes Talking Domain-Driven Design with David Laribee Part 2, Deep Fried Bytes Eric Evans on Domain Driven Design, .NET Rocks Domain-Driven Design Community Eric Evans on Domain Driven Design Jimmy Nilsson on Domain Driven Design Domain-Driven Design Wikipedia What I’ve Learned About DDD Since the Book, Eric Evans Domain Driven Design, Alt.Net Podcast Applying Domain-Driven Design and Patterns: With Examples in C# and .NET, Jimmy Nilsson Domain-Driven Design Discussion Group DDD: Putting the Model to Work by Eric Evans The Official DDD Site

  • Spreadsheet RDBMS

    - by John Nilsson
    I'm looking for a software (or set of software) that will let me combine spreadsheet and database workflows. Data entry in spreadsheet to enable simple entry from clipboard, analysis based on joins, unions and aggregates and pivot/data pilot summaries. So far I've only found either spreadsheets OR db applications but no good combination. OO base with calc for tables doesn't support aggregates f.ex. Google Spreadsheet + Visualizaion API doesn't support unions or joins, zoho db doesn't let me paste from clipboard. Any hints on software that could be used? Basically I'm trying to do some analysis of my personal bank transactions. Problem 1, ETL. The data has to be moved from my bank to a database. My current solution is to manually copy and paste the data into one spread sheet per account from my internet bank. Pains: Not very scriptable. Lots of scrolling to reach the point to paste. Have to apply sorting and formatting to the pasted data each time. Problem 2, analysis. I then want to aggregate the different accounts in one sweep to track transfers per type of transfer over all accounts. The actual aggregation is still unsolved because I can't find a UNION equivalent in the spreadsheets I've tried.

  • Command line: Map network drive

    - by Seb Nilsson
    How do I write a command line in a .bat or .cmd that maps a network drive? I want the script to first check if the drive-letter is mapped, and if it is delete it and then map the drive. I only have the mapping-command right now. Please help me fill in the blanks: REM Check if drive exists, if it does, delete it @echo off net use q: /persistent:yes \\localhost\C$\MyFolder pause Are there any of the parameters wrong? Any that should be added?

  • Searching a list of tuples in python

    - by Niclas Nilsson
    I'm having a database (sqlite) of members of an organisation (less then 200 people). Now I'm trying to write an wx app that will search the database and return some contact information in a wx.grid. The app will have 2 TextCtrls, one for the first name and one for the last name. What I want to do here is make it possible to only write one or a few letters in the textctrls and that will start to return result. So, if I search "John Smith" I write "Jo" in the first TextCtrl and that will return every single John (or any one else having a name starting with those letters). It will not have an "search"-button, instead it will start searching whenever I press a key. One way to solve this would be to search the database with like " SELECT * FROM contactlistview WHERE forname LIKE 'Jo%' " But that seems like a bad idea (very database heavy to do that for every keystroke?). Instead i thought of use fetchall() on a query like this " SELECT * FROM contactlistview " and then, for every keystroke, search the list of tuples that the query have returned. And that is my problem: Searching a list is not that difficult but how can I search a list of tuples with wildcards?

  • ASP.NET: Compress ViewState

  • C#: File-size format provider

    - by Seb Nilsson
    Is there any easy way to create a class that uses IFormatProvider that writes out a user-friendly file-size? public static string GetFileSizeString(string filePath) { FileInfo info = new FileInfo(@"c:\windows\notepad.exe"); long size = info.Length; string sizeString = size.ToString(FileSizeFormatProvider); // This is where the class does its magic... } It should result in strings formatted something like "2,5 MB", "3,9 GB", "670 bytes" and so on.

  • ASP.NET: Moving ViewState to bottom of page

    - by Seb Nilsson
    What are the latest and greatest ways to move ViewState to bottom of the page Can this be done in a IHttpHandler that can be specified in the web.config to intercept requests to "*.aspx"? <httpHandlers> <add verb="*" path="*.aspx" type="MyApp.OptimizedPageHandler" /> <httpHandlers> Other options is that this could be done in a IHttpModule, but that is not as performant, as it will intercept all requests. Also it could be done in an a class deriving from the Page or MasterPage-class, but this is not as modular. Are there any performance penalties to this?

  • ASP.NET MVC on IIS6

    - by Seb Nilsson
    Where can I find some good pointers on best practices for running ASP.NET MVC on IIS6? I haven't seen any realistic options for web-hosts who provide IIS7-hosting yet. Mostly because I don't live in the U.S. So I was wondering on how you best build applications in ASP.NET MVC and make it easily available to deploy on both IIS6 and IIS7. Keep in mind that this is for standard web-hosts, so there is no access to ISAPI-filters or special settings inside IIS6. Are there anything else one should think about when developing ASP.NET MVC-applications to target IIS6? Any functions that doesn't work? UPDATE: One of the bigger issues is the thing with routes. The pattern {controller}/{action} will work on IIS7, but not IIS6 which needs {controller}.mvc/{action}. So how do I make this transparent? Again, no ISAPI and no IIS-settings, please.

  • ASP.NET MVC: Making routes/URLs IIS6 and IIS7-friendly

    - by Seb Nilsson
    I have an ASP.NET MVC-application which I want deployable on both IIS6 and IIS7 and as we all know, IIS6 needs the ".mvc"-naming in the URL. Will this code work to make sure it works on all IIS-versions? Without having to make special adjustments in code, global.asax or config-files for the different IIS-versions. bool usingIntegratedPipeline = HttpRuntime.UsingIntegratedPipeline; routes.MapRoute( "Default", usingIntegratedPipeline ? "{controller}/{action}/{id}" : "{controller}.mvc/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); Update: Forgot to mention. No ISAPI. Hosted website, no control over the IIS-server.

  • How to diff two regions of the same file in Eclipse

    - by Thomas Nilsson
    I'm a TDDer and often have a need to refactor out common or similar code. If it is exactly the same there is no big problem, Eclipse can almost always do that by itself. But to get there I'm finding myself often looking at similar, but not identical, code fragments in the same, or even different, files. It would be very handy if there was a possibility to mark two regions and get Eclipse (or some other tool) to mark the differences. With this information it would be much simpler to iteratively move the regions closer until they are the same and then activate the Extract Method refactoring. It can be done in Emacs of course, but I'd like to have this readily available from Eclipse. Any pointers?

What are the general pros and cons?
