Introduction With the winter weather, we’ve been having brownouts and power losses more frequently. I wanted to purchase a UPS to protect my equipment from this, but I also wanted to receive alerts when the power goes out, and possibly shutdown equipment. For this, I need an Uninterruptible Power Supply (UPS) and a computer to monitor it with. Hardware As you guessed by now, I’m going to be using my Raspberry Pi to monitor the UPS. I’m using the Raspberry Pi because it is a low power device, it is always on (hosting a webserver, Unifi controller, and a few other things), and can be run off the UPS it is monitoring. ...

This was the first I’d heard of this. The information first went public via email (below), and then started popping up on DSLReports. ...

In particular, the EdgeRouter Lite, which is touted as being the world’s first router under $100 capable of passing one million packets per second (1Mpps). In contrast, I’ve read that the TP-Link WDR-3600 can pass about 25Kpps. This is partly due to the hardware in the WDR-3600, and partly due to the software (OpenWrt). I wanted to try out the EdgeRouter Lite (ERL) and see how it performed. ...

Introduction Put on your tinfoil hats, boys and girls! Today, we’re talking about security, encryption, and GPG! PGP vs OpenPGP vs GPG PGP Pretty Good Privacy (PGP) was a program created to encrypt/decrypt data in 1991 by Phil Zimmermann. Zimmermann formed PGP Incorporated, which was acquired serveral times and is now owned by Symantec. Fun fact - in 1993 the US government charged Zimmerman with “munitions export without a license”. At the time, cryptography systems with keys over 40 bits were considered a weapon, and since PGP used 128 bit keys, Zimmerman was in violation of the law. However, Zimmerman was able to circumvent this by publishing the entire source code of PGP in a physical book (that could be scanned with OCR and recompiled into source code), since the export of books was protected by the First Amendment. Today, PGP is no longer considered a weapon, but still cannot be exported to a specific list of individuals/countries. ...
