To configure Ruby from within UltraEdit, use the following settings under Tool Configuration:
- Command Line should be
C:\Ruby191\bin\ruby.exe "%f".
- Set Working Directory to
%p. Note that there are no quotes.
- Under the Options, set Program Type to DOS Program.
- Set Output to Capture Output, and tweak your preferences as desired.
Don’t forget to also download the wordfile!
You can use CSS 3 Selectors to change properties of elements (such as for links) without having to write dynamic PHP code:
ul.lectures a[href $=".ppt"] {
background:url(../images/icons/icon_ppt.gif)
center right no-repeat; padding-left:20px;
}
The example above will display a Microsoft PowerPoint icon for file names ending in “.ppt”.
NetBeans 6.8 fails to uninstall correctly on my system. Instead, I am faced with the following error message:
The specified target component - nb-base/6.8.0.0
was not found in the registry. The installer
can continue as if the target component was not specified.
Click Yes to continue, No to exist the installer.
I have already posted this to the NetBeans forums.
I have moved to Raleigh, North Carolina. My new address is:

I built a computer sometime in 2006 and then subsequently upgraded several times along the way. Here are the specifications:
- AMD Athlon 64 X2 Dual Core Processor 3800+ 2.01 Ghz
- ASUS A8N-SLI Deluxe 939 NVIDIA nForce4 SLI Motherboard
- CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM DDR 400 (PC 3200) TWINX2048-3200C2
- Western Digital Caviar SE16 WD3200KS 320GB 7200 RPM
- EVGA 256-P2-N363-TX GeForce 6600LE 256MB 128-bit DDR PCI Express x16 SLI
It’s been four years since then, and the machine still performs well and I can run all of the latest software that I use on a daily basis without difficulty.
Unlike the C programming language, Python assignments are statements, not expressions. Therefore the common C idiom of:
while (line = fgets(f)) {
/* do something with the line */
}
is not possible to implement directly.
However, effbot.org provides several alternatives using iterators or the while True idiom. I recently discovered the built-in iter() function as well:
for line in iter(f.readline, "END"):
... do something with line ...
While working a problem from the Waterloo Programming Contents, I found that the sample solution used the GCC internal function used the GCC internal function __builtin_popcount(unsigned int x).
This function returns the number of 1-bits in x, and we can emulate a similar operation in Python 2.6 (PEP 3127) or above using the quick and dirty snippet:
bin(x).count('1')
Sometimes you want to be able to run a script through the interactive Python Shell that comes with IDLE, but using a different text editor (such as UltraEdit). In this case, you want to run IDLE from another program. To do so:
idle.py -r scriptname.py
or
idle.pyw -r scriptname.py
Strangely, the -r command-line argument doesn’t appear to be in the Python documentation for IDLE at all.
Note: The idle.py script is typically located at C:\Python31\Lib\idlelib, or very close to it.
Some other notes on specific to UltraEdit:
- An example Command Line is:
C:\Python31\Lib\idlelib\idle.pyw -r "%f".
- For Program Type, set to Dos Program, not Windows Program.
- Do not capture any Command Output.
It looks like the NetBeans IDE is unable to do unit tests if you are developing your code using a Python 3 interpreter. You’ll hit the following wall when trying to run a test:
File "C:\Program Files\NetBeans 6.8\python\
\nb_test_runner.py", line 216
except ValueError, e:
^
SyntaxError: invalid syntax
Finished in 0.0 seconds.
0 tests, 0 failures, 0 errors
Perhaps NetBeans 7.0 will address this issue.
How do you manually remove a MySQL Server Instance? I have MySQL Server 7.0 listed as one of the server instances when running the MySQL Server Instance Configuration Wizard.
