I got myself two Buffalo WLAE-AG300N devices to function as a WiFi bridge (I couldn’t run an ethernet cable from A to B, but both devices there were wired).
Just found out that when you loose utility power, and it comes back up, then these devices do not automatically power up: you *have* to press the power button.
Bummer.

Since SuSE 11.2, when installing then the CLI version of YaST looks horrible on the first (Ctrl-Alt-F1) console before you do your first reboot.
Workarounds:

Two years ago, I posted a batch file that gets the parent directory of the batch file that runs.
It was convoluted, using substrings and intermediate environment variables so you needed setlocal.
This one does not any more: for both the directory of the batch file, and the parent directory of that directory, one-liners suffice:
| echo batchfile=%0 | |
| echo full=%~f0 | |
| setlocal | |
| for %%d in (%~dp0.) do set Directory=%%~fd | |
| echo Directory=%Directory% | |
| for %%d in (%~dp0..) do set ParentDirectory=%%~fd | |
| echo ParentDirectory=%ParentDirectory% | |
| endlocal |

Programmers scale: time versus project completeness
I totally agree that Paint.NET is the best free image and photo editor on Windows.
Writing quality software takes time, not only when writing it in spare time like Rick Brewster does. Getting things “right” is a tedious process and often will set you back: just watch the graph on the right.
So I’m not surprised that it took a very long time after the first Paint.NET 4.0 idea in 2008 to get “close” to a release.
And indeed, it looks like Rick has become much closer which will please many people waiting for Paint .NET 4.
I’m really glad with the announcement that Paint.NET v3.5.11 BETA is now available – Paint.NET Discussion & Questions – Paint.NET Forum.
Edit: while writing this, the final Paint.NET v3.5.11 came out.
It paves the way for Paint .NET 4.0 update in the future, and fixes/improves quite a few things.
A few quotes from it:
This is probably not the update you were expecting I need to push out an update to v3.5 in preparation for the eventual release of v4.0 […] releasing a “beta” today […] I’ll be pushing out the Final/RTM in a few days.
The primary goal of this update is preparing for the v4.0 release: v3.5.10 will not be able to offer the v4.0 update, but v3.5.11 will. […]
Here are the changes for this release:
- Fixed: The Gaussian Blur effect was incorrectly calculating alpha values for non-opaque pixels. (http://forums.getpaint.net/index.php?/topic/18483-gaussian-blur-mistreats-alpha/)
- Improved performance of the Sharpen effect by about 25%
- Improved performance of the Median effect by about 30%
- Improved performance of the Fragment effect by about 40%
- Improved performance of the Unfocus effect by about 100%
- Reduced memory usage when many selection manipulation operations are in the history/undo stack (the undo data is now saved to disk)
- The built-in updater now supports upgrading to paint.net 4.0 (once it’s available)
There have been rumors floating around that Paint.NET is “dead.” This is not true!

StackOverflow has [WayBack] quite a [WayBack] few questions [WayBack] on creating [WayBack] empty text files from a batch file.
Most answers involve the [WayBack] NUL special file (which is not available on one special version of Windows [WayBack] Windows Fundamentals for Legacy PCs, but can easily be retrofitted).
[WayBack] This is the solution I use most often:

Everyone knows there is a size difference between a gigabyte of memory, and a gigabyte of disk space.
The former is 102410241024, the latter is 100010001000.
To facilitate this, I’ve created a C# class UnitPrefixes containing quite a few constants and readonly values.
The class is below, but a few interesting facts first:
I used the Wikipedia pages Binary Prefix and Metric Prefix (I could also have used File Size) for the unit names and abbreviations.
Note that BitsPerByte is a const I needed too, and I will probably add constants for 512 and 4096, as you see those often in computing as well.
The below sample code is also available as a changeset on BeSharp.CodePlex.com. Read the rest of this entry »

Getting substrings in a batchfile requires you to use the %…:~…% syntax as explained by Rob van der Woude.
Note this only works on batch file variables, so not on batch/function arguments (%1, %2, …)and for-loop indexes (%%f, etc).
This code gets the leftmost three characters of var:
set var=%var:~3%
echo %var%

While researching some other historic information about Delphi, I bumped into this thread: New DPMI host – delphi.
If is a small thread describing what kinds and versions of DPMI hosts were available to run Turbo Pascal based programs.
DPMI stands DOS Protected Mode Interface: a way for real mode DOS programs to access protected mode features (mainly memory above the 1 megabyte barrier).
I had plainly forgotten that the DPMI host shipped with Delphi 1, and wasn’t aware you could have a 32-bit DPMI host at all.
Some other memory related abbreviations from that era: Read the rest of this entry »
