NSA-proof your e-mail in 2 hours

You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. The way that e-mail was originally designed to work. Today we kill your excuses. Now fair warning: it took me about two days to figure the stuff out you’re going to see in this blogpost, starting from knowing basically nothing about modern e-mail servers. So bookmark this blog post, block off a Saturday next month, and get it done. Edit Some people are complaining that the NSA is pulling all the e-mail over the wire anyway, so encrypting your own server is stupid. In the next two hours, we’re going to fix this. You’re going to host your own mail.It’s going to be encrypted on the server, locked-on-boot, SSH on reboots to unlockWhile we’re at it, let’s fix some things that annoy me about GMail:Better SPAM detection.

You Are the Network btcd: Not your mom’s Bitcoin daemon | Conformal Systems, LLC. We are pleased to announce that btcd, our full-node bitcoind alternative written in Go, is finally ready for public testing! The installation instructions and source code can be found on github at: A Brief History Back in May, we first announced our plans to release btcd. Over the next month, we released btcjson, btcdb, and btcscript. What Took so Long? As typically happens with development, several things came up, all of which took a few days (or a week) here and there. The following list is a brief overview of the various things that were tackled: So, as you can see from the list above, we were able to cram quite a bit in 10 weeks! Separate Chain and Wallet While implementing the wallet and starting to build the GUI, we quickly realized that there is, what we consider, a fundamental design flaw in the other implementations we have seen to date. Why Separate Chain and Wallet? Multiple devices and thin wallets can also be supported based on this design.

ExtraBee Open-Source Radio Module by Jeremy Willden There are a lot of radio modules out there, but few of them allow you to customize the firmware inside. We started this project so we could have a radio module to use with our Arduino and other projects, but with the ability for anyone to customize the firmware for their own projects. We're big fans of open source, so we're using an Atmel processor so we can make it compatible with the Arduino development environment, and we used an Atmel 802.15.4/Zigbee chip. We added a RF power amplifier (PA) and low-noise amplifier (LNA) to extend the range of the radio module, much like the higher power versions of these closed-source modules, and adopted a popular module footprint and pinout so it can be made drop-in compatible (with further software development). The prototypes currently both send and receive radio packets with each other and we've also tested them with an XBee-PRO, but it should work with any device that adheres to the 802.15.4 standard.

It was certainly true as little as a few years ago (2005). What's the risk with today's devices? Flash based solid state disks would seem to be the ideal virtual storage device... In every other respect you can treat them in exactly the same way as a hard drive:- same interface, same software model. In the smaller form factors like 1.8" and 2.5" - the gap in capacity between SSDs and hard drives has disappeared. What's wrong with this utopian vision? And why is it that even if you were offered a flash SSD accelerator for your server absolutely FREE you might still hesitate about installing it? The answer explains why the flash SSD server acceleration market still isn't a billion dollar plus market - even 4 years after I first posed this exact same question.
