Try a Story Idea Prompt
So if you are stuck for ideas, here are some prompts:
* What was your favorite childhood pet?
* Where was your most memorable vacation?
* What topic most inspired you in grade school?
* Where is a place in the world you'd like to visit?
* What is the most adventurous thing you have done?
* Who was an influential authority in your subject discipline?
* Or just describe a collection of things such as
o Five attributes of a great writer
o The top technology gadgets of the future
o Most important discoveries in your field
o Favorite cars, vegetables, flowers, tools
o Collection of things that don't belong
Why is it I have such a hard time writing down stories?

To decode what the remote was sending, I used an oscilloscope and a small photodiode. The photodiode generates a small amount of voltage when light hits it, and responds to changes in light level quickly enough that the oscilloscope can draw a really nice plot of the signal. I have a Parallax USB oscilloscope, which is perfect for showing the command pulses and is just fast enough to find the modulation frequency. As an aside, I’m really happy with the Parallax oscilloscope for projects like this. It is simple to use and I love being able to save images to share with people.
Here’s what two of the commands from the dimmer remote look like. The top signal is the “fade lights up” command, and the bottom one is “fade lights down”:
I'm working on a project that uses data in JSON format (www.json.org). It took me a while to get it going in processing, so I thought I'd post what I did here. If there's a better way (which undoubtedly there is!), please let me know.

Here are the steps I took (on Windows):
1. Download http://www.json.org/java/json.zip from json.org. Save it in a some directory, which I'll call %DOWNLOAD_HOME%.
2. Unzip it. Be sure you preserve the archive's directory structure (/org/json/) when you unzip the file.
3. Change directory into %DOWNLOAD_HOME%orgjson

If you've installed the recently released "Service Pack 2" (SP2) for
Windows XP, you have automatically installed a new firewall on your
PC that might be blocking VNC connections. To create an "exception"
for VNC, follow these instructions:
1. Click Start, click Run, type Wscui.cpl, and then click OK to open
Windows Firewall.
2. Click the Exceptions tab, and de-select the "Don't Allow Exceptions"
radio-button.
3. Click Add Port to display the Add a Port dialog box.
4. Enter port number "5900" or whatever port you've got VNC on that
PC to listen on (port number = 5900 + "VNC Display Number").
5. Select the TCP protocol.
6. In the Name field, type "VNC".
7. Click Change Scope to view or to set the scope for the port
exception, and then click OK.
8. Click OK to close the Add a Port dialog box.
That should do it! More info here:

You need to tell subversion what mime-type to use. Just use the command: svn propset svn:mime-type 'text/html' FILENAME or svn propset svn:mime-type 'image/jpeg' FILENAME For more info: http://svnbook.red-bean.com/en/1.4/svn.advanced.props.file-portability.html#svn.advanced.props.special.mime-type It's also possible to configure your Subversion client to automatically set each file's mime-type. For example, by modifying ~/.subversion/config to resemble [miscellany] enable-auto-props = yes [auto-props] *.html = svn:mime-type=text/html For more info: http://svnbook.red-bean.com/en/1.1/ch07.html#svn-ch-7-sect-1.3.2

So when I got to Maker Day at Maker Faire yesterday afternoon, I was happy to find that Limor Fried, the founder of Adafruit, was giving a presentation on how to start your own business selling kits. This is a growing business right now, as people look for reasons to teach their kids how to solder, or just want to build a neat device. (Adafruit teamed with the Maker Store to offer the infamous TV-B-Gone kit that garnered a lot of attention at CES this year.)

This is the first in a series of articles about generating sound with an Arduino. The goals are to generate good quality sound which can be used to play simple tones, stored music, sampled sound, and even act as a MIDI synthesizer. I will cover the basic design, including code and hardware that anyone can use to add sound to Arduino microcontroller projects.
The first step is to look what has already been done. We want to explore many possible options for sound generation and resolve which is best for given situations. I hope to spark some discussion so please comment with information links, advice, suggestions and general opinions.
gdb and simulavr are the backend of AVR studio. With gdb and simulavr you can do the same things you can do with AVR studio. Ubuntu has in its repository some ready packages. Look for gcc-avr, binutils-avr, avr-libc, avrdude, gdb-avr, simulavr. Just install them, that's it Cool The downside is that you don't have a GUI, you probably need to simulate your code from the command line.
This tutorial will demonstrate the following development process: Write C programs in AVR Studio. Compile them into a .hex file using the AVR-GCC compiler (which integrates into AVR Studio). Simulate the target AVR chip and debug the code within AVR Studio. Program the actual chip using the AVRISP mkII USB device, which is attached to our target chip with a special 6-pin cable. Once programmed, the chip runs the program in your circuit.

Memcached will dramatically speed up MediaWiki. Some pages on my site, like the Main Page took 40 seconds to load before Memcached, but only 7 after installing Memcached. "Memcached is a high-performance, distributed memory object caching system". Memcached is essentially a database caching system which is object orientated, and works even if the database is updated. (MySQL caching discards the entire cache when a table is changed)

- short (because people don't read much online);
- rich in information scent, clearly summarizing the target article;
- front-loaded with the most important keywords (because users often scan only the beginning of list items);
- understandable out of context (because headlines often appear without articles, as in search engine results); and
- predictable, so users know whether they'll like the full article before they click (because people don't return to sites that promise more than they deliver).
