Applescripts and Sandboxing – How to download attachments

I just updated to OS 10.8 (Mountain Lion) yesterday and immediately face-planted into their sandbox. Any new Mac application distributed in the App Store will have to stay in a tight sandbox, and explicitly request permissions to do things on your computer. This is great for security, but it also breaks a lot of older


Ultra Wideband Power Transfer Networks Publishing Errors

Dr. Binboga Siddik Yarman has published a fantastic reference on RF matching network theory and design: Design of Ultra Wideband Power Transfer Networks, by Wiley 2010 An excellent resource, I was using his (and Carlin’s, to be fair) powerful Real Frequency Direct Technique for synthesizing a broadband double matching circuit for some RF amplifiers. He


Motorola RAZR MAXX SIM Card Removed Error

I’m not sure what happened, but I rebooted my phone (Verizon; Motorola RAZR MAX) today and up came a screen claiming that the SIM card had recently been removed and I needed to put in my account name and password to unlock my phone. Except nothing would take. I tried resetting my MOTOBLUR account, and


Spicy Steamed Edamame

Had just finished dinner and these pictures of ridiculous sandwiches got me thinking about food again. Now, some of these are just way over the top–you know, fry something fatty and add bacon with an egg and anyone loves it when drunk. But the creativity really inspires me and you can always “fix” these if


Salivating at the Possibilities…

I’ve recently been pretty excited about the possibilities of the Raspberry Pi project in terms of do-it-yourself hardware and hacking fun. Having a full-featured computer on an open-source platform for $25 is pretty amazing. Given the video and network capabilities they’ve demonstrated, I’d like to take a look at the hardware design (I believe their


Windows XP 3GB RAM Switch

Problem When using Xilinx System Generator to synthesize a large design, after some time the synthesis will halt and a warning about running out of memory will appear. This occurs when synthesizing the WARP OFDM Reference model from Rice University on Windows XP. The problem is that individual applications can address up to 3GB of


WARP FPGA Board v2.1 to v2.2 Pin Definitions

Problem The supply of WARP boards is limited, however there is a small number of version 2.1 FPGA boards that I’ve stumbled across. The only problem is that the basic OFDM reference model will not work with these boards since there was an error in their design, causing some of the pins to be routed


Removing Comments from a Configuration File

Problem Sometimes you just gotta remove all blank and commented lines from a configuration file in bash. I didn’t like a lot of the Google hits for this. Solution The following code removes all blank lines and all commented lines (including indented ones!) from the passed file. This does NOT deal with inline comments, since


Enabling mod_rewrite with self-hosted WordPress site

Problem Permalinks and Pages in my new WordPress site (you’re looking at it!) didn’t work. I would publish a page and it’d all go well except the Page simply wasn’t accessible to the public Internet. I just got a 404 error. This was silly, since I knew WordPress didn’t keep folders in its installation directory, and instead
