• Ubuntu server loses exactly 5 minutes once in a while

  - by Harold Smith

  I noticed that my server, an Ubuntu server 12.04, was losing time. I figured the hardware clock was off or maybe dying due to a faulty CMOS battery. I installed NTP to ensure the drift would be corrected, but to no avail. During a day it would lose 20 minutes or so. To debug, I created a small cron job to check against a remote servers time, which I knew to be correct. The script calculates the difference in seconds between local and remote time. The result was interesting. It seems to be losing exactly 5 minutes several times during the day. Look at this log (difference from remote server noted in seconds): Tue Oct 23 03:30:02 CEST 2012: 284 Tue Oct 23 03:35:02 CEST 2012: 284 Tue Oct 23 03:40:01 CEST 2012: 285 Tue Oct 23 03:45:02 CEST 2012: 285 Tue Oct 23 03:50:02 CEST 2012: 285 Tue Oct 23 03:55:02 CEST 2012: 284 Tue Oct 23 04:00:02 CEST 2012: 284 Tue Oct 23 04:05:01 CEST 2012: 285 Tue Oct 23 04:10:01 CEST 2012: 285 Tue Oct 23 04:15:02 CEST 2012: 585 Tue Oct 23 04:20:02 CEST 2012: 584 Tue Oct 23 04:25:02 CEST 2012: 584 Tue Oct 23 04:30:02 CEST 2012: 584 Tue Oct 23 04:35:01 CEST 2012: 585 Tue Oct 23 04:40:01 CEST 2012: 585 Tue Oct 23 04:45:02 CEST 2012: 585 Tue Oct 23 04:50:02 CEST 2012: 584 Tue Oct 23 04:55:02 CEST 2012: 584 Tue Oct 23 05:00:02 CEST 2012: 584 Tue Oct 23 05:05:01 CEST 2012: 585 Tue Oct 23 05:10:01 CEST 2012: 585 Tue Oct 23 05:15:02 CEST 2012: 585 Tue Oct 23 05:20:02 CEST 2012: 584 Tue Oct 23 05:25:02 CEST 2012: 584 Tue Oct 23 05:30:02 CEST 2012: 584 Tue Oct 23 05:35:01 CEST 2012: 585 Tue Oct 23 05:40:01 CEST 2012: 585 Tue Oct 23 05:45:02 CEST 2012: 584 Tue Oct 23 05:50:02 CEST 2012: 584 Tue Oct 23 05:55:02 CEST 2012: 584 Tue Oct 23 06:00:02 CEST 2012: 584 Tue Oct 23 06:05:03 CEST 2012: 584 Tue Oct 23 06:10:02 CEST 2012: 584 Tue Oct 23 06:15:01 CEST 2012: 585 Tue Oct 23 06:20:02 CEST 2012: 584 Tue Oct 23 06:25:02 CEST 2012: 584 Tue Oct 23 06:30:02 CEST 2012: 584 Tue Oct 23 06:35:02 CEST 2012: 584 Tue Oct 23 06:40:02 CEST 2012: 584 Tue Oct 23 06:45:01 CEST 2012: 585 Tue Oct 23 06:50:02 CEST 2012: 584 Tue Oct 23 06:55:01 CEST 2012: 585 Tue Oct 23 07:00:02 CEST 2012: 584 Tue Oct 23 07:05:02 CEST 2012: 584 Tue Oct 23 07:10:02 CEST 2012: 584 Tue Oct 23 07:15:02 CEST 2012: 584 Tue Oct 23 07:20:02 CEST 2012: 584 Tue Oct 23 07:25:02 CEST 2012: 584 Tue Oct 23 07:30:01 CEST 2012: 585 Tue Oct 23 07:35:02 CEST 2012: 584 Tue Oct 23 07:40:02 CEST 2012: 584 Tue Oct 23 07:45:02 CEST 2012: 584 Tue Oct 23 07:50:02 CEST 2012: 584 Tue Oct 23 07:55:02 CEST 2012: 584 Tue Oct 23 08:00:01 CEST 2012: 585 Tue Oct 23 08:05:02 CEST 2012: 584 Tue Oct 23 08:10:02 CEST 2012: 584 Tue Oct 23 08:15:02 CEST 2012: 584 Tue Oct 23 08:20:02 CEST 2012: 584 Tue Oct 23 08:25:02 CEST 2012: 584 Tue Oct 23 08:30:01 CEST 2012: 585 Tue Oct 23 08:35:02 CEST 2012: 584 Tue Oct 23 08:40:02 CEST 2012: 584 Tue Oct 23 08:45:02 CEST 2012: 584 Tue Oct 23 08:50:02 CEST 2012: 584 Tue Oct 23 08:55:02 CEST 2012: 584 Tue Oct 23 09:00:02 CEST 2012: 584 Tue Oct 23 09:05:03 CEST 2012: 584 Tue Oct 23 09:10:02 CEST 2012: 584 Tue Oct 23 09:15:02 CEST 2012: 584 Tue Oct 23 09:20:02 CEST 2012: 584 Tue Oct 23 09:25:02 CEST 2012: 584 Tue Oct 23 09:30:01 CEST 2012: 584 Tue Oct 23 09:35:02 CEST 2012: 584 Tue Oct 23 09:40:02 CEST 2012: 584 Tue Oct 23 09:45:02 CEST 2012: 584 Tue Oct 23 09:50:02 CEST 2012: 584 Tue Oct 23 09:55:02 CEST 2012: 584 Tue Oct 23 10:00:01 CEST 2012: 584 Tue Oct 23 10:05:02 CEST 2012: 584 Tue Oct 23 10:10:07 CEST 2012: 584 Tue Oct 23 10:15:02 CEST 2012: 584 Tue Oct 23 10:20:02 CEST 2012: 884 Tue Oct 23 10:25:02 CEST 2012: 884 Tue Oct 23 10:30:02 CEST 2012: 883 Tue Oct 23 10:35:01 CEST 2012: 884 Tue Oct 23 10:40:02 CEST 2012: 884 Tue Oct 23 10:45:02 CEST 2012: 884 Tue Oct 23 10:50:02 CEST 2012: 884 Tue Oct 23 10:55:02 CEST 2012: 1184 Tue Oct 23 11:00:02 CEST 2012: 1183 Tue Oct 23 11:05:01 CEST 2012: 1184 Tue Oct 23 11:10:02 CEST 2012: 1184 Tue Oct 23 11:15:02 CEST 2012: 1184 Tue Oct 23 11:20:02 CEST 2012: 1184 This does not seem to be faulty CMOS battery in my opinion.

• What is good usage scenario for Rackspace Cloud Files CDN (powered by AKAMAI) [closed]

  - by Andrew Smith

  I have just setup my website as static page via Rackspace CDN / Akamai. www.example.co.uk is an alias for d9771e6f24423091aebc-345678991111238fabcdef6114258d0e1.r61.cf3.rackcdn.com. d9771e6f24423091aebc-345678991111238fabcdef6114258d0e1.r61.cf3.rackcdn.com is an alias for a61.rackcdn.com. a61.rackcdn.com is an alias for a61.rackcdn.com.mdc.edgesuite.net. a61.rackcdn.com.mdc.edgesuite.net is an alias for a63.dscg10.akamai.net. a63.dscg10.akamai.net has address 63.166.98.41 a63.dscg10.akamai.net has address 63.166.98.40 a63.dscg10.akamai.net has IPv6 address 2001:428:4c02::cda8:ecb9 a63.dscg10.akamai.net has IPv6 address 2001:428:4c02::cda8:ed09 The HTTP header: HTTP/1.0 200 OK Last-Modified: Fri, 19 Oct 2012 23:27:41 GMT ETag: fdf9e14b77def799e09e8ce815a521da X-Timestamp: 1350689261.23382 Content-Type: text/html X-Trans-Id: tx457979be3bd746c2b4e5403a1189cdbc Cache-Control: public, max-age=900 Expires: Sat, 27 Oct 2012 22:18:56 GMT Date: Sat, 27 Oct 2012 22:03:56 GMT Content-Length: 7124 Connection: keep-alive I am wondering, if it's really the fastest solution to power the website? By investigating it thru http://www.just-ping.com/ it seems, that from many places the ping is very high, and during quick investigation I found that they use GeoIP to resolve addresses based on WHOIS, which is not accurate and because of that from many places the ping is above 300ms (for example, if ISP is in balgladore and request is routed to bangladore even if it's 300ms, for period of 1 month), while by just using Amazon Web Services and Route 53 Anycast DNS servers and only 4 EC2 instances it seems that for example India is always below 100ms, while using Akamai it goes above 300ms in some cases, and this is because Route 53 is using BGP. By quickly checking the Akamai, it seems that they are not getting feedback from the traffic - the high ping stays constant even if I keep downloading large files and videos, which is opposite to what they say on their website. They state, that they optimize the performance by taking feedback from the requests, while it seems they just use GeoIP with per City resolution (which are mostly big cities). Because of this, AWS with Route 53 / Anycast DNS seems to be much more reliable, as well EdgeCast which is using BGP, but I dont know how much does it cost to deploy static website. Actually, I dont know if EdgeCast is not a lie, because from isolated places there are many errors - so their performance is at the cost of quality of delivery, because of BGP switching the routes during transfer of large files. So I was wondering, what is really Akamai good for, because they dont seem to pose any strength in any field in what I do understand now, except they offer some software based WAF on their website, but what I really care about is the core distribiution, so the question is? Is really Akamai good for Videos? For static websites? ??? I found so far AWS most usable with most consistent ping and stable transfers.

• How are minimum system requirements determined?

  - by Michael McGowan

  We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

• ejabberd starts slow and fails

  - by Michael Tanner

  I installed ejabberd and tried to set it up. On my server there are strict rules which allow only several services and denies everything else. I experienced starting problems with my iptables rules and found out that ejabberd works when I allow everything in the iptables and restore my rules afterwards. Then it also works for connecting, registering and else. What could be the problem in my rules? Attached here: http://fixee.org/paste/s5s744j/ Would be nice to get a correction straight on fixee if I made a mistake. Thanks in advance. Edit 1: In the log files there are no specific error messages during startup.

• C#/.NET Little Wonders: Getting Caller Information

  - by James Michael Hare

  Originally posted on: http://geekswithblogs.net/BlackRabbitCoder/archive/2013/07/25/c.net-little-wonders-getting-caller-information.aspx Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. There are times when it is desirable to know who called the method or property you are currently executing.  Some applications of this could include logging libraries, or possibly even something more advanced that may server up different objects depending on who called the method. In the past, we mostly relied on the System.Diagnostics namespace and its classes such as StackTrace and StackFrame to see who our caller was, but now in C# 5, we can also get much of this data at compile-time. Determining the caller using the stack One of the ways of doing this is to examine the call stack.  The classes that allow you to examine the call stack have been around for a long time and can give you a very deep view of the calling chain all the way back to the beginning for the thread that has called you. You can get caller information by either instantiating the StackTrace class (which will give you the complete stack trace, much like you see when an exception is generated), or by using StackFrame which gets a single frame of the stack trace.  Both involve examining the call stack, which is a non-trivial task, so care should be done not to do this in a performance-intensive situation. For our simple example let's say we are going to recreate the wheel and construct our own logging framework.  Perhaps we wish to create a simple method Log which will log the string-ified form of an object and some information about the caller.  We could easily do this as follows: 1: static void Log(object message) 2: { 3: // frame 1, true for source info 4: StackFrame frame = new StackFrame(1, true); 5: var method = frame.GetMethod(); 6: var fileName = frame.GetFileName(); 7: var lineNumber = frame.GetFileLineNumber(); 8: 9: // we'll just use a simple Console write for now 10: Console.WriteLine("{0}({1}):{2} - {3}", 11: fileName, lineNumber, method.Name, message); 12: } So, what we are doing here is grabbing the 2nd stack frame (the 1st is our current method) using a 2nd argument of true to specify we want source information (if available) and then taking the information from the frame.  This works fine, and if we tested it out by calling from a file such as this: 1: // File c:\projects\test\CallerInfo\CallerInfo.cs 2:  3: public class CallerInfo 4: { 5: Log("Hello Logger!"); 6: } We'd see this: 1: c:\projects\test\CallerInfo\CallerInfo.cs(5):Main - Hello Logger! This works well, and in fact CallStack and StackFrame are still the best ways to examine deeper into the call stack.  But if you only want to get information on the caller of your method, there is another option… Determining the caller at compile-time In C# 5 (.NET 4.5) they added some attributes that can be supplied to optional parameters on a method to receive caller information.  These attributes can only be applied to methods with optional parameters with explicit defaults.  Then, as the compiler determines who is calling your method with these attributes, it will fill in the values at compile-time. These are the currently supported attributes available in the  System.Runtime.CompilerServices namespace": CallerFilePathAttribute – The path and name of the file that is calling your method. CallerLineNumberAttribute – The line number in the file where your method is being called. CallerMemberName – The member that is calling your method. So let’s take a look at how our Log method would look using these attributes instead: 1: static int Log(object message, 2: [CallerMemberName] string memberName = "", 3: [CallerFilePath] string fileName = "", 4: [CallerLineNumber] int lineNumber = 0) 5: { 6: // we'll just use a simple Console write for now 7: Console.WriteLine("{0}({1}):{2} - {3}", 8: fileName, lineNumber, memberName, message); 9: } Again, calling this from our sample Main would give us the same result: 1: c:\projects\test\CallerInfo\CallerInfo.cs(5):Main - Hello Logger! However, though this seems the same, there are a few key differences. First of all, there are only 3 supported attributes (at this time) that give you the file path, line number, and calling member.  Thus, it does not give you as rich of detail as a StackFrame (which can give you the calling type as well and deeper frames, for example).  Also, these are supported through optional parameters, which means we could call our new Log method like this: 1: // They're defaults, why not fill 'em in 2: Log("My message.", "Some member", "Some file", -13); In addition, since these attributes require optional parameters, they cannot be used in properties, only in methods. These caveats aside, they do let you get similar information inside of methods at a much greater speed!  How much greater?  Well lets crank through 1,000,000 iterations of each.  instead of logging to console, I’ll return the formatted string length of each.  Doing this, we get: 1: Time for 1,000,000 iterations with StackTrace: 5096 ms 2: Time for 1,000,000 iterations with Attributes: 196 ms So you see, using the attributes is much, much faster!  Nearly 25x faster in fact.  Summary There are a few ways to get caller information for a method.  The StackFrame allows you to get a comprehensive set of information spanning the whole call stack, but at a heavier cost.  On the other hand, the attributes allow you to quickly get at caller information baked in at compile-time, but to do so you need to create optional parameters in your methods to support it.

• Setting up phpMemCacheAdmin on CentOS 5.5

  - by Bill Smith

  I have been able to setup phpMemCacheAdmin (http://code.google.com/p/phpmemcacheadmin/) on CentOS and am able to view the localhost MemCache statistics however whenever I add other MemCached nodes the config is never changed. I am fairly certain it has something to do with permissions however I am unable to track down what exactly needs to be done, or how to do it. The install was pretty straightforward: wget http://phpmemcacheadmin.googlecode.com/files/phpMemCacheAdmin-1.1.3r161.tar.gz tar xvzf phpMemCacheAdmin-1.1.3r161.tar.gz chmod +w Config/Memcache.ini But, it also states that Apache has rw right in the temp file folder (default : Temp/) and the entire config directory (Config/) -- that is the part I am unsure of. Help!

• Cleaning your BizTalk Build Server

  - by Michael Stephenson

  Just a little note for myself this one.At one of my customers where it is still BizTalk 2006 one of the build servers is intermittently getting issues so I wanted to run a script periodically to clean things up a little.  The below script is an example of how you can stop cruise control and all of the biztalk services, then clean the biztalk databases and reset the backup process and then click everything off again.This should keep the server a little cleaner and reduce the number of builds that occasionally fail for adhoc environmental issues.REM Server Clean ScriptREM =================== REM This script is ran to move the build server back to a clean state echo Stop Cruise Controlnet stop CCService echo Stop IISiisreset /stop echo Stop BizTalk Servicesnet stop BTSSvc$<Name of BizTalk Host><Repeat for other BizTalk services> echo Stop SSOnet stop ENTSSO echo Stop SQL Job Agentnet stop SQLSERVERAGENT echo Clean Message Boxsqlcmd -E -d BizTalkMsgBoxDB -Q "Exec bts_CleanupMsgbox"sqlcmd -E -d BizTalkMsgBoxDB -Q "Exec bts_PurgeSubscriptions"  echo Clean Tracking Databasesqlcmd -E -d BizTalkDTADb -Q "Exec dtasp_CleanHMData" echo Reset TDDS Stream Statussqlcmd -E -d BizTalkDTADb -Q "Update TDDS_StreamStatus Set lastSeqNum = 0" echo Force Full Backupsqlcmd -E -d BizTalkMgmtDB -Q "Exec sp_ForceFullBackup" echo Clean Backup Directorydel E:\BtsBackups\*.* /q  echo Start SSOnet start ENTSSO echo Start SQL Job Agentnet start SQLSERVERAGENT echo Start BizTalk Servicesnet start BTSSvc$<Name of BizTalk Host><Repeat for other BizTalk services> echo Start IISiisreset /start echo Start Cruise Controlnet start CCService

• For a Javascript library, what is the best or standard way to support extensibility

  - by Michael Best

  Specifically, I want to support "plugins" that modify the behavior of parts of the library. I couldn't find much information on the web about this subject. But here are my ideas for how a library could be extensible. The library exports an object with both public and "protected" functions. A plugin can replace any of those functions, thus modifying the library's behavior. Advantages of this method are that it's simple and that the plugin's functions can have full access to the library's "protected" functions. Disadvantages are that the library may be harder to maintain with a larger set of exposed functions and it could be hard to debug if multiple plugins are involved (how to know which plugin modified which function?). The library provides an "add plugin" function that accepts an object with a specific interface. Internally, the library will use the plugin instead of it's own code if appropriate. With this method, the internals of the library can be rearranged more freely as long as it still supports the same plugin interface. This could also support having different plugin interfaces to modify different parts of the library. A disadvantage of this method is that the plugins may have to re-implement code that is already part of the library since the library's internal functions are not exported. The library provides a "set implementation" function that accepts an object inherited from a specific base object. The library's public API calls functions in the implementation object for any functionality that can be modified and the base implementation object includes the core functionality, with both external (to the API) and internal functions. A plugin creates a new implementation object, which inherits from the base object and replaces any functions it wants to modify. This combines advantages and disadvantages of both the other methods.

• Use CompiledQuery.Compile to improve LINQ to SQL performance

  - by Michael Freidgeim

  After reading DLinq (Linq to SQL) Performance and in particular Part 4  I had a few questions. If CompiledQuery.Compile gives so much benefits, why not to do it for all Linq To Sql queries? Is any essential disadvantages of compiling all select queries? What are conditions, when compiling makes whose performance, for how much percentage? World be good to have default on application config level or on DBML level to specify are all select queries to be compiled? And the same questions about Entity Framework CompiledQuery Class. However in comments I’ve found answer  of the author ricom 6 Jul 2007 3:08 AM Compiling the query makes it durable. There is no need for this, nor is there any desire, unless you intend to run that same query many times. SQL provides regular select statements, prepared select statements, and stored procedures for a reason.  Linq now has analogs. Also from 10 Tips to Improve your LINQ to SQL Application Performance   If you are using CompiledQuery make sure that you are using it more than once as it is more costly than normal querying for the first time. The resulting function coming as a CompiledQuery is an object, having the SQL statement and the delegate to apply it.  And your delegate has the ability to replace the variables (or parameters) in the resulting query. However I feel that many developers are not informed enough about benefits of Compile. I think that tools like FxCop and Resharper should check the queries  and suggest if compiling is recommended.

• Does Unity support disabling the global application menu?

  - by Michael E

  I'm fairly excited for Unity, as it looks like a promising new direction for Ubuntu. However, I do have a concern - will it be possible to use Unity without the global menu? I have my window manager set to focus-follows-mouse/sloppy focus, and find the productivity gains to be immense. Sloppy focus is incompatible, however, with global menus, as it is possible for the focus to change while you move from window to menu. Will Unity support an option to use window menus while still using Unity?

• How to turn off Libnotify notifications only when sound is in muted state?

  - by Michael Butler

  I have a multimedia keyboard that allows me to easily mute the sound (Ubuntu 12.04). It would be nice to "link" this to also turn off libnotify messages that pop-up in the top right corner (i.e. Pidgin messages). So when Ubuntu is muted, no libnotify messages would pop up. When not muted, messages show as normal. Is this possible with a script of some kind or would it require changing source code?

• 2d & 3d CAD software on the MAC [closed]

  - by Mark Smith

  Hey I was wondering what 2d & 3d CAD softwares people use on the mac? There are a couple of other questions like this on the site but they're over a year old and knowing how fast paced the software game is I thought i'd repost! I use MacDraft for my 2d drafting and the same companies Interiors Pro for my 3d work, have done for a while. I used Rhino 4.0 at uni but being a student I had to find software that wasn't thousands of £$£$!! thus stumbling onto the Microspot products. Anybody using the software or found any other bargains out there?

• Problems with EmusicJ on Ubuntu 14.04

  - by Michael Dykes

  I am running Ubuntu 14.04 in my new machine and have a subscription to emusic (because I used it before in my Windows days because of the great selection of classical music). I have used it on my old machine (running older versions of Ubuntu) with some success but am having difficulties doing so now. I am trying to use EmusicJ but do not/cannot remember how to do so. I have downloaded the program and unzipped it and ran the following command in a terminal: ./emusic If I remember correctly, once I go to the emusic site and download my music, the EmucisJ program should open and begin downloading the music through that program but this time it is not and I have already wiped my old box in order to give it to a friend. Any help is appreciated as I would like to continue with Emusic, but if I cannot get this resolved I will likely have to cancel my subscription and find a better alternative. Thanks.

• Losing partitions after every reboot

  - by Winston Smith

  I have an Acer laptop with one hard disk, which up until yesterday had 4 partitions: Recovery Partition (13GB) C: (140GB) D: (130GB) OEM Partition (10GB) I read that the OEM partition has all the stuff needed to restore the laptop to the factory settings, but since I'd already created restore disks and I needed the space, I wanted to get rid of it. Yesterday, I used diskpart to do that. In diskpart, I selected the OEM partition and issued the delete partition override command which removed it. Then I extended the D: partition into the unused space using windows disk management. Everything worked fine, until I rebooted my laptop, at which point the D: drive vanished. Looking in windows disk management again, I can see that there's an OEM partition of 140GB, which is obviously my D: drive. So I used EASEUS Partition Master and assigned a drive letter to the 'OEM' partition and I was able to access my files again. However, every time I reboot, it reverts back. How do I fix this permanently?

• How can I create a symlink to the location that Ubuntu 10.10 mounts a CD?

  - by Michael Curran

  In Ubuntu 10.10, when I insert a CD or DVD into my optical drive, the system mounts the CD in a folder called /media/XYZ where XYZ is the disk's label. This has cause problems with Wine, as in order for an application to verify that an application's CD is present, Wine uses a symlinks to point to a mounted CD's folder. In this case, that folder must be /media/XYZ, but when using a different application, the folder would be different. I would like to know if there is a way to create a symlink that will always point to the mounted folder from a given /dev/cdrom* device, or how to force the system to always mount CDs to the same address (i.e. /media/cdrom).

• Wordpress Queue like Tumblr?

  - by Michael Hopkins

  Hi. Is there a way to give Wordpress the queue functionality that Tumblr has? Tumblr's queue, for those who don't know, is a way to space posts out without assigning specific post dates. For example, a Tumblr queue might be set to post every four hours between 9am and 5pm. Tumblr would drop the front post in the queue at 9am, 1pm and 5pm every day. Posts are added to the queue by clicking "add to queue" instead of "publish." It's quite simple. How can this feature be added to Wordpress?

• C#/.NET Little Wonders: Interlocked Read() and Exchange()

  - by James Michael Hare

  Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Last time we discussed the Interlocked class and its Add(), Increment(), and Decrement() methods which are all useful for updating a value atomically by adding (or subtracting).  However, this begs the question of how do we set and read those values atomically as well? Read() – Read a value atomically Let’s begin by examining the following code: 1: public class Incrementor 2: { 3: private long _value = 0; 4:  5: public long Value { get { return _value; } } 6:  7: public void Increment() 8: { 9: Interlocked.Increment(ref _value); 10: } 11: } 12:  It uses an interlocked increment, as we discuss in my previous post (here), so we know that the increment will be thread-safe.  But, to realize what’s potentially wrong we have to know a bit about how atomic reads are in 32 bit and 64 bit .NET environments. When you are dealing with an item smaller or equal to the system word size (such as an int on a 32 bit system or a long on a 64 bit system) then the read is generally atomic, because it can grab all of the bits needed at once.  However, when dealing with something larger than the system word size (reading a long on a 32 bit system for example), it cannot grab the whole value at once, which can lead to some problems since this read isn’t atomic. For example, this means that on a 32 bit system we may read one half of the long before another thread increments the value, and the other half of it after the increment.  To protect us from reading an invalid value in this manner, we can do an Interlocked.Read() to force the read to be atomic (of course, you’d want to make sure any writes or increments are atomic also): 1: public class Incrementor 2: { 3: private long _value = 0; 4:  5: public long Value 6: { 7: get { return Interlocked.Read(ref _value); } 8: } 9:  10: public void Increment() 11: { 12: Interlocked.Increment(ref _value); 13: } 14: } Now we are guaranteed that we will read the 64 bit value atomically on a 32 bit system, thus ensuring our thread safety (assuming all other reads, writes, increments, etc. are likewise protected).  Note that as stated before, and according to the MSDN (here), it isn’t strictly necessary to use Interlocked.Read() for reading 64 bit values on 64 bit systems, but for those still working in 32 bit environments, it comes in handy when dealing with long atomically. Exchange() – Exchanges two values atomically Exchange() lets us store a new value in the given location (the ref parameter) and return the old value as a result. So just as Read() allows us to read atomically, one use of Exchange() is to write values atomically.  For example, if we wanted to add a Reset() method to our Incrementor, we could do something like this: 1: public void Reset() 2: { 3: _value = 0; 4: } But the assignment wouldn’t be atomic on 32 bit systems, since the word size is 32 bits and the variable is a long (64 bits).  Thus our assignment could have only set half the value when a threaded read or increment happens, which would put us in a bad state. So instead, we could write Reset() like this: 1: public void Reset() 2: { 3: Interlocked.Exchange(ref _value, 0); 4: } And we’d be safe again on a 32 bit system. But this isn’t the only reason Exchange() is valuable.  The key comes in realizing that Exchange() doesn’t just set a new value, it returns the old as well in an atomic step.  Hence the name “exchange”: you are swapping the value to set with the stored value. So why would we want to do this?  Well, anytime you want to set a value and take action based on the previous value.  An example of this might be a scheme where you have several tasks, and during every so often, each of the tasks may nominate themselves to do some administrative chore.  Perhaps you don’t want to make this thread dedicated for whatever reason, but want to be robust enough to let any of the threads that isn’t currently occupied nominate itself for the job.  An easy and lightweight way to do this would be to have a long representing whether someone has acquired the “election” or not.  So a 0 would indicate no one has been elected and 1 would indicate someone has been elected. We could then base our nomination strategy as follows: every so often, a thread will attempt an Interlocked.Exchange() on the long and with a value of 1.  The first thread to do so will set it to a 1 and return back the old value of 0.  We can use this to show that they were the first to nominate and be chosen are thus “in charge”.  Anyone who nominates after that will attempt the same Exchange() but will get back a value of 1, which indicates that someone already had set it to a 1 before them, thus they are not elected. Then, the only other step we need take is to remember to release the election flag once the elected thread accomplishes its task, which we’d do by setting the value back to 0.  In this way, the next thread to nominate with Exchange() will get back the 0 letting them know they are the new elected nominee. Such code might look like this: 1: public class Nominator 2: { 3: private long _nomination = 0; 4: public bool Elect() 5: { 6: return Interlocked.Exchange(ref _nomination, 1) == 0; 7: } 8: public bool Release() 9: { 10: return Interlocked.Exchange(ref _nomination, 0) == 1; 11: } 12: } There’s many ways to do this, of course, but you get the idea.  Running 5 threads doing some “sleep” work might look like this: 1: var nominator = new Nominator(); 2: var random = new Random(); 3: Parallel.For(0, 5, i => 4: { 5:  6: for (int j = 0; j < _iterations; ++j) 7: { 8: if (nominator.Elect()) 9: { 10: // elected 11: Console.WriteLine("Elected nominee " + i); 12: Thread.Sleep(random.Next(100, 5000)); 13: nominator.Release(); 14: } 15: else 16: { 17: // not elected 18: Console.WriteLine("Did not elect nominee " + i); 19: } 20: // sleep before check again 21: Thread.Sleep(1000); 22: } 23: }); And would spit out results like: 1: Elected nominee 0 2: Did not elect nominee 2 3: Did not elect nominee 1 4: Did not elect nominee 4 5: Did not elect nominee 3 6: Did not elect nominee 3 7: Did not elect nominee 1 8: Did not elect nominee 2 9: Did not elect nominee 4 10: Elected nominee 3 11: Did not elect nominee 2 12: Did not elect nominee 1 13: Did not elect nominee 4 14: Elected nominee 0 15: Did not elect nominee 2 16: Did not elect nominee 4 17: ... Another nice thing about the Interlocked.Exchange() is it can be used to thread-safely set pretty much anything 64 bits or less in size including references, pointers (in unsafe mode), floats, doubles, etc.  Summary So, now we’ve seen two more things we can do with Interlocked: reading and exchanging a value atomically.  Read() and Exchange() are especially valuable for reading/writing 64 bit values atomically in a 32 bit system.  Exchange() has value even beyond simply atomic writes by using the Exchange() to your advantage, since it reads and set the value atomically, which allows you to do lightweight nomination systems. There’s still a few more goodies in the Interlocked class which we’ll explore next time! Technorati Tags: C#,CSharp,.NET,Little Wonders,Interlocked

• Process Power to the People that Create Engagement

  - by Michael Snow

  Organizations often speak about their engagement problems as if the problem is the people they are trying to engage - employees,  partners, customers and citizens.  The reality of most engagement problems is that the processes put in place to engage are impersonal, inflexible, unintuitive, and often completely ignorant of the population they are trying to serve. Life, Liberty and the Pursuit of Delight? How appropriate during this short week of the US Independence Day Holiday that we're focusing on People, Process and Engagement. As we celebrate this holiday in the US and the historic independence we gained (sorry Brits!) - it's interesting to think back to 1776 to the creation of that pivotal document, the Declaration of Independence. What tremendous pressure to create an engaging document and founding experience they must have felt. "On June 11, 1776, in anticipation of the impending vote for independence from Great Britain, the Continental Congress appointed five men — Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert Livingston — to write a declaration that would make clear to people everywhere why this break from Great Britain was both necessary and inevitable. The committee then appointed Jefferson to draft a statement. Jefferson produced a "fair copy" of his draft declaration, which became the basic text of his "original Rough draught." The text was first submitted to Adams, then Franklin, and finally to the other two members of the committee. Before the committee submitted the declaration to Congress on June 28, they made forty-seven emendations to the document. During the ensuing congressional debates of July 1-4, 1776, Congress adopted thirty-nine further revisions to the committee draft. (http://www.constitution.org) If anything was an attempt for engaging the hearts and minds of the 13 Colonies at the time, this document certainly succeeded in its mission. ...Their tools at the time were pen and ink and parchment. Although the final document would later be typeset with lead type for a printing press to distribute to the colonies, all of the original drafts were hand written. And today's enterprise complains about using "Review and Track Changes" at times.  Can you imagine the manual revision control process? or lack thereof?  Collaborative process? Time delays? Would  implementing a better process have helped our founding fathers collaborate better? Declaration of Independence rough draft below. One of many during the creation process. Great comparison across multiple versions of the document here. (from http://www.ushistory.org/): While you may not be creating a new independent nation, getting your employees to engage is crucial to your success as a company in today's world. Oracle WebCenter provides the tools that power engagement. Employees that have better tools for communication, collaboration and getting their job done are more engaged employees. Better engaged employees create more engaged customers and partners. 12.00 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 -"/ /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif"; mso-fareast-font-family:"Times New Roman";}

• Subdividing a polygon into boxes of varying size

  - by Michael Trouw

  I would like to be pointed to information / resources for creating algorithms like the one illustrated on this blog, which is a subdivision of a polygon (in my case a voronoi cell) into several boxes of varying size: http://procworld.blogspot.nl/2011/07/city-lots.html In the comments a paper by among others the author of the blog can be found, however the only formula listed is about candidate location suitability: http://www.groenewegen.de/delft/thesis-final/ProceduralCityLayoutGeneration-Preprint.pdf Any language will do, but if examples can be given Javascript is preferred (as it is the language i am currently working with) A similar question is this one: What is an efficient packing algorithm for packing rectangles into a polygon?
