Ubuntu 13.10 with TCP-IR (TCP Instant Recovery / FEC) enabled kernel v3.4.83

How would FEC (Forward Error Correction) enabled TCP/IP stack for Linux sound like? Yep, I know you're interested and want it. Start by checking these two links. http://www.ietf.org/proceedings/87/slides/slides-87-tcpm-8.pdf http://tools.ietf.org/html/draft-flach-tcpm-fec-00

Digi One, PortServer etc. and double enter problem

There's annoying problem with Digi RS232 - Ethernet products (also sold BlackBox branded). Many if not most telnet clients are incompatible with their server implementation and treat single enter press as two enter presses. Incompatible clients are at least SecureCRT, Putty and one Microsoft includes with Windows. Teraterm works ok.

Measuring temperature with OpenWrt and submitting values to EmonCMS

I'm using OpenWrt with following customizations to send temperature readings to EmonCMS. Hardware is noname Ralink RT3052 router (WR512-3GN) and Dallas DS9097U compatible USB 1-wire adapter. Main reason for going with Image Generator instead of compiling custom firmware was to keep binary and API compatibility with packages from stock OpenWrt repository. Package selection below leaves 168kB free on JFFS2 filesystem. Drop editor, Luci etc. and you'll have a lot more free. If you don't need to patch init scripts like I did due bug in WR512-3GN support you can simply install packages and apply scripts over top of official OpenWrt release flashed to your router.

Updating Samsung SSD firmware without Windows

Connecting Samsung 9 Series 900X3C running Windows 7 x64 to Onkyo TX-NR626 amplifier using Bluetooth A2DP

After replacing incredible slow Sandisk SSD Samsung ships this model with Crucial CT240M500SSD3 and doing clean bloatware free Win7 install I noticed I couldn't connect to my Onkyo TX-NR626 using bluetooth anymore. Reason was that Microsoft doesn't provide required drivers for A2DP bluetooth profile required.
