Ellen Degeneres: Generous Waitress Gets One Giant Tip
Sarah Hoidahl showed that even the smallest act of kindness can have huge rewards. The New Hampshire waitress picked up the tab for two National Guard soldiers furloughed due to the government shutdown. Buying her customers’ meal cost her $27.75, but she was repaid hundreds of times over during her appearance on “Ellen”!
Kyle Landry: Pianist
Kyle Landry was born the youngest of two children on March 8th, 1990 in Massachusetts, USA. As a young child of 3, he had an immediate curiosity of his mother’s piano playing. Many times he would dance around the room while she played him Ragtime by Scott Joplin. When his older sister began piano lessons in 1994, he was very jealous, and begged for lessons. At the time, Kyle was only 4 years old, so both his parents, and piano teacher advised that he waited a few more years before starting. Four years later, his mother agreed to take Kyle to his first piano lesson on July 1998, at 8 years-old, to a local piano teacher, Mrs. Kaminsky. Kyle immediately developed a passion for the instrument and soon discovered he had a natural ability for performing. By the age of 12, playing piano was simply not enough, so he began improvising on simple tunes such as Pachelbel’s Canon, which eventually lead into his immense interest in composition for years to come. Kyle continued studying piano w
Aliso the Geek | A coder in love with WordPress
The more I code, the more fascinated I become with the idea of how much I don’t know about programming. New techniques come into being every day, and I just can’t keep up with all of them. On this blog, I try to at least keep up with the WordPress world. I love making WordPress plugins, and I love learning more about the WordPress API. Hopefully anyone interested in the same can take something from my blog every now and then. Why “Aliso the Geek”? Where’s the N? I went to a small college where the instructors took attendance. My maiden name (Kleinschmidt) caused my first name to get cut off on the attendance sheet: “Kleinschmidt, Aliso.” Teachers usually understood it was Alison. One teacher that I’d had before called me Aliso all quarter as a joke. The nickname then followed me to work, where my boss expanded it to “Aliso the Geek.” They even got me a birthday cake one year with that nickname on it.
Periodic Table | Minute Physics
Hopefully you noticed the big temperature control at the top of the page. You can use it to see how elements behave at different temperatures. You can see either magnetic properties or states of matter by changing the title (in the top left) between “Magnetism” and “States”. There are also other settings you can access by clicking on the settings icon ( ).
Thanks to Periodic Videos, you can click on any of the elements to see an awesomely informative video about that element!
Magnetic Phase Transitions
As Henry explained in his video, matter can take on one of five magnetic states: Ferromagnetic, Antiferromagnetic, Paramagnetic, Diamagnetic, or Ferrimagnetic (we’re going to ignore that last one for now).
Some elements can change between ferromagnetic, antiferromagnetic, and paramagnetic by heating or cooling them. This is a lot like elements transition between solid, liquid, and gas. This “melting” of magnetic states generally happens in this order: ferromagnetic, antiferromagnetic, paramagnetic.
The ferromagnetic “melting” temperature is called the Curie Temperature (Tc), and the antiferromagnetic “melting” temperature is called the Néel temperature (Tn). Sometimes elements may change right from ferromagnetic to paramagnetic, others transition between all three, and others never become ferromagnetic or antiferromagnetic at all!

windytan.com: random hacks and assorted infodumps by Oona Räisänen
If, on the sending end, you don’t have netcat, but do have bash, you can do `cat file.tar > /dev/tcp/192.168.1.243/12345` which redirects to a tcp socket using a crazy bash-only extension.
Need to quickly transfer a file from one computer to another? They don’t have AirDrop and you can’t find a memory stick? No worries; netcat comes to the rescue. This tip works on Linux as well as OSX.
I’m going to suppose you’re on the same LAN, the subnet address space begins with 192.168, and you want to transfer a file called file.tar. First, on the receiving computer, type ifconfig|grep 192.168 to find out its IP address. Then make netcat listen to a port by typing nc -l 12345 > file.tar. On the sending side, type nc 192.168.1.243 12345 < file.tar (or whatever the IP address and file name are). And magic happens!

I like to write my de/modulators from scratch. Simple and hassle-free. They work on raw floating-point PCM using Perl's pack() and unpack() and the built-in trigonometric functions sin(), cos(), or I may write them in C99 if high throughput is required. I use SoX for sinc filtering, resampling, and file format conversions. For simple FSK stuff, minimodem is the perfect choice.
In most radio-related projects I've used a cheap USB DVB-T receiver stick, also known as RTL-SDR. Some FM radio related projects were done using a modified "worldband receiver".
For waveforms I use my own program called Oscillo. Baudline and librsvg are useful for signals rendering as well. I use Inkscape, GIMP and ImageMagick for design and compositing.
