Brilliant: site where you can Search UTF8 Unicode Characters.
If you know part of the name of a Unicode character, you can now try and find it, then copy/paste it from that site.
Edit: 20160403: that site disappeared, but this one works: Unicode Character Search and Shapecatcher.com: Unicode Character Recognition still works.

Delphi seemingly makes the distinction between reference and value types disappear, especially because it hides the ^derefererncing operator for most usages:
Rudy Velthuis wrote a great article on pointers in general. Though it was in the Delphi 2009 timeframe, almost everything is very valid. A few things are missing, some additions are below.
I’m not going into deep detail here right now, just a few notes to get people interested going.
Hopefully I will some time in the future to either go into more detail, or point to articles that do.
Even with those additions to Rudy’s list, I’m not 100% sure everything is complete now (:

Electric Imp – that wants to power The Internet of Things using imps – is introducing some really interesting hardware, one of the devevelopment kits combining Arduino and Imp on one board:
Duino: Arduino, with Imp
Featuring an ATMEGA328 processor, this board is compatible with the Arduino Uno but instead of having a USB-serial port on it, it has an Imp socket. You can use a modified version of the Arduino IDE to update the ATMEGA code from anywhere in the world when an Imp is plugged in, and use simple serial commands in your Arduino programs to control other Imp devices.
The ATMEGA will operate standalone when no imp card is inserted.
Dimensions: 72mm x 54mm x 14mm
Power supply: USB Mini-B socket (5v) or 2.1mm barrel jack (7-12v)
Price: $20
Some must read links:

Two quotes:
Apple peripheral devices may request more than 500 mA (Milliamps) at 5 V (Volts) from a port to function or to allow for faster charging. Such Apple peripheral devices include:
- Apple MacBook Air SuperDrive (when connected to supported computers)
- Aluminum Wired Keyboard*
- iPod
- iPhone
- iPad
Open System Profiler to find more information about peripheral power requirements, or contact the manufacturer of your peripheral. For the most accurate information about power usage, make sure your device is connected directly to your Apple computer or display before opening System Profiler.
All this because of the iPad charging challenge.

In the previous post, you saw some XPath to find the ProviderManifestToken attribute in an .edmx file.
Writing XPath queries can be quite consuming, so it is nice of you can test it somewhere on-line.
Out of the on-line XPath testers, these two worked best:
Both of them support namespaces, including these XPath functions: local-name and namespace-uri.
These failed:
If you have more on-line tools that work: please let me know!
Edit (20120524T0930):
Danny Thorpe tweeted an interesting comment:
@jpluimers If you’re compiling XPath support, make note of whether it’s XPATH 1.0 or 2.0. I think .NET only implements XPATH 1.0
Indeed, .NET only supports XPath 1.0, and worse, .NET 4 introduced a couple of issues with XSLT (see XPath and XSLT 2.0 for .NET? – Stack Overflow).
Luckily there are some goot XPath 2.0 libraries for .NET (see XPath 2.0 Libraries for .Net – Stack Overflow).

Yes. Dorothy. There are people using the ADO .NET Entity Framework with SQL Server 2000 in parallel of moving towards a more modern Microsoft SQL Server version.
Entity Framework is lovely for developing data-centric applications.
By default, Visual Studio 2010 will target SQL Server 2008 as a database. That is fine, but it is kind of invisible it does: there is no property or dialog where you can change this.
A few caveats:

Raymond Chen:
what if you don’t want the fault-tolerant heap? For example, during program development, you probably want to disable the fault-tolerant heap for your program: If the program is crashing, then it should crash so you can debug it!

The introduction of the Ribbon in Office 2007 and 2010 often makes me ask “why are things so complicated now, that were so easy until Office 2003”.
One of the things that were very close together in Word 2003, was converting text to and from tables: they were in adjecent menu items.
Not any more, as you can see in the Convert text to a table or vice versa topic on the Microsoft site. There is even a Dummies article on this topic.
Summarized:
Of course the keyboard shortcuts are “easy” to remember: Alt, N, T, V
