DATAPUISTOKEMISTI

My B593s had ancient Sonera branded firmware that has DNS issues when IPv6 is active. At least IPv6 reverse queries stall causing long delays. There's some rumors going that Sonera provides updated firmware over-the-air, but I couldn't trigger update despite trying hard. Might be because I was using Elisa SIM card. Since Elisa does have fairly recent firmware available for download I thought why not use Elisa firmware instead - get IPv6 bug fixed, have correct operator settings as default and also future updates should work without extra hacks.

Clean Windows 7 install with latest Office 2013 from Office 365 and latest Skype for Business 2015 (The Application Formerly Known As Lync) also from Office 365. Problem is that "New Skype Meeting" option is missing from Outlook calendar options. There's just empty space where ribbon bar button should be.

Ericsson has manufactured probably millions of faulty 3G WWAN modules that hang after few minutes to few hours of use. There's driver and firmware updates out that may sometimes help but usually only by extending time before hang bit longer.

If you install IE 11 before enabling "Microsoft Update" feature of "Windows Update" on Windows 7 you'll be stuck with "Use your Start menu to check for updates" error message. Solution is to open IE, then hit ALT to show menus, go to Tools, Compatibility View settings and enable "Use Microsoft compatibility lists".

I had to upgrade to new Smartmontools 6.4 on my Ubuntu 12.04 server as old version lacks Prolific PL2773 USB3 to SATA bridge support.

There's probably proper api to do this, but everything is in German and all I wanted to do is toggle status of single power outlet from script. curl --data "F0=S" http://admin:admin@192.168.1.3/ctrl.htm -o /dev/null
