The IETF has published a bunch of new RFCs to update HTTP/1.1 specs and make the 15 year old 2616 obsolete: RFC 7230: Message Syntax and Routing RFC 7231: Semantics and Content RFC 7232: Conditional Requests RFC 7233: Range Request RFC 7234: Caching RFC 7235: Authentication RFC 7236: Authentication Scheme Registrations RFC 7237: Method Registrations RFC 7238: the 308 status code RFC 7239: Forwarded HTTP extension Here I listed a few changes:

I had the first contact to 37signalsbasecamp by reading Getting Real when it was published in 2009. I just finished their new book “Remote”. Since I’m working a lot from my home office since a few month I find more and more reasons for working remote. The latest one is from “The-Thinking-Clearly” by Rolf Dobelli: “Studies prove, that commuting is the main reason for dissatisfaction” Two books I can really recommend!

To increase Visual Studio performance several things can be done. One is to configure Windows Defender:

I really like IPMI so I don’t have to walk to the data center to turn on a machine. But the web interface is so 90s. As I live life on the console I whished I had a command line utility. Et voilà:

My VCS story began with Microsoft Visual Source Safe. I was happy… I had my files versioned. I could view differences in file versions. I could restore previous versions. I could view the history of a file. … until the IDE started to crash, I had corrupted files and so on. http://www.flickr.com/photos/nesster/5823554695/ So I gave CVS and then SVN and TFS a try. I was happy… I could work with branches I could version source code “over HTTPS”.

A while ago I dropped a piece of code that prevents from unlimited callback nesting: Chaining asynchronous JavaScript calls Today I was hacking some Angular JS code and found myself nesting callbacks. So I updated the CallChain to an Angular JS factory: Here is how it is used:

The Windows Client Certificate Enrollment Protocol [MS-WCCE] defines a sanitizing mechanism e.g. for common names in section 1.3.2.4 and section 3.1.1.4.1.1. After I gave my favorite search engine a try and ensured there is no built-in function to call I built my own. Here it is:

Oder warum sollten sich mehrere Anwendungen nicht dieselbe Datenbank teilen? http://www.flickr.com/photos/breville/10731809645/sizes/l/ Viele Köche verderben den Brei: Diseconomy of Scale Eine gemeinsame Datenbank (geteilt zwischen Anwendungen und/oder Teams) sorgt für unterschiedliche Interessen und erhöhten Absprachebedarf, damit es nicht zu einer Art Wildwuchs kommt. Wenn keine klaren Schnittstellen definiert sind sinkt die Produktivität aufgrund des erhöhten Kommunikationsaufwandes. Das gilt in Firmen unter Abteilungen und Mitarbeitern, genauso wie für Software-Projekt-Teams als auch für Software selbst.

http://www.flickr.com/photos/toofarnorth/8670157331/ Aus der RFC 2616: “It is a generic, stateless, protocol” Das heißt, das Fundament auf dem wir aufsetzen ist Sitzungslos. Wenn das Applikations-Framework, egal ob mit Web Forms oder MVC, oder Python, oder PHP, oder Rails…, das respektiert, wird es den Anforderungen des Web gerecht: Skaliert besser – Ich brauche mir im NLB-Szenario (Network Load Balancing) keine Gedanken über Shared Memory machen oder mit dem ASP.NET State-Server einen SPOF (Single Point of Failure) einführen.

I have a test environment for an application. From time to time I take the database to my local development environment. A smaller database log means less network latency and a faster local reproduction scenario. After a while of pumping data into a MSSQL Server instance the log can grow a bit – even if there is a lot of free space left. Shrinking is NOT GOOD at all, but I don’t have 50gigs of space left to pull up that database on my local machine.

I have a test environment for an application. From time to time I take the database to my local development environment. A smaller backup means less network latency and a faster local reproduction scenario. Since 2008 Microsoft SQL Server comes with a feature called backup compression. I gave it a try and so I ran the two following statements in competition: BACKUP DATABASE [XXX] TO DISK = N'D:\DATA\SQL\BACKUP\Uncompressed.bak' WITH COPY_ONLY, NOFORMAT, NOINIT, NAME = N'Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10 GO vs.

Designing architecture for a scalable system always involves thinking asynchronous parts. For example: placing an order to a system. At first sight this process of course requires feedback. What happens if the order is invalid because it contains incorrect data? Especially for the non-technical stakeholders it is hard to imagine how this can be accomplished. Therefor it is always helpful to have an example that is taken from the non- technical world.

The following call disables File-System-Redirection on 64bit Windows in WOW mode (e.g. Accessing Program Files and ending up in Program Files (x86)): // Minimum client Windows XP Professional x64 Edition or higher // Minimum server Windows Server 2003 with SP1 or higher NativeMethods.Kernel32.Wow64DisableWow64FsRedirection(pt1);

Mixed language content was in the past a good indicator for phishing – just not as professional as the real provider. Today I received an e-mail by Adobe that asks me to change my password, as they were being hacked in the past and beside passwords (not even hashes? what the hell), program code as well as certificates have been stolen or compromised. I was a bit scared that Adobe now offers a mixed language site especially after what happened to them…

NDepend is a tool that offers a wide range of features to let developers analyze a .NET code base. It comes with about 200 built in rules. But there are a few default rules that do not fit “my rules”. This blog post shows how to customize one and even more important why. Avoid namespaces with few types In general types should be placed in namespaces. But compiler generated types (caused by linq queries) are sometimes not.

But there are a few default rules that do not fit “my rules”. This blog post shows how to customize one and even more important why. Avoid namespaces with few types I observed that the original rule outputs an unnecessary line for namespace {} because of the compiler generated classes (caused by linq queries).

Avoid defining multiple types in a source file I completely agree, with one exception: When having a generic and a non-generic type e.

Types too big I use extension methods to collect several functionality for e.g. framework types as string. Each Extension-Class is typically spread across several files and partial to keep overview and maintainability.

Static fields should be prefixed with a ’s_' I use underdashes for instance fields and therefor I have a custom rule for static fields.

Patrick Smacchia’s NDepend is a great tool to improve code quality and should be run quite regularly. It can be run as a strand alone GUI tool, from inside Visual Studio and as part of your build process. I’ll use the tool over the next few weeks to analyze and improve the quality of one of my personal code bases. I’ll try to share my experiences beside tips and tricks as well as giving feedback to Patrick.

At a customer we have e.g. a country list in a select form element. It’s special because it has an option group called “top countries”. Inside the list are duplicates, that are listed in the option group “all countries” to. The browser tends to select the latest matching element – which in this special case makes no sense. Here is a directive that ensures the first matching element is selected:

Yester day the yearly ICE conference happened in Lingen again. As I’m deep deep down in a project near it’s v1.0 release I haven’t had a lot time there beside my session. But at least enough to talk to Ingo, Thomas, Lars, Peter, Frank, Holger and a few others. Thanks a lot to the organization team making this happen year over year again.

I like to speed up my coding with for instance code snippets. Here is a new one: The markup for the snippet file:

We have HTML5 native video support (also with Flash or Silverlight fallback for the oh so old school browsers) so why the heck do some people out there still make it so hard to consume content – in this case Oracle (best known for providing Malware with their installers?!?): I remember that I bought software, at least eight years ago, through Digital River. These times ago I already thought there is space for improvement.
