Low budget fanless ZFS NAS

Dunno how this will end up as I did again mistake of digging up one of those Wyse Z90D7 terminals from junk pile. This time my idea is to use it for NAS after upgrading RAM from 2GB to 6GB and adding two 1TB 2.5" USB3 disks. Wyse being fanless and with host powered disks this should be decent combo. Then add FreeNAS 9.2 and ZFS with snapshots. Snapshots are mandatory feature as I'm sending this to friend of mine for christmas present. He's one of those who insist on installing every virus and cryptolocker he can find. With data backed up to NAS and protected by daily snapshots recovery is much easier than ever before. With assumption that he'll save important data to network drive which will then probably corrupt it all due me using inappropriate hardware...

Set folder dates to newest file inside (using PowerShell)

Someone (not me this time) screwed up and while transferring content from old server to new one ended up messing all folder timestamps. Folders now have date when copy was made instead of preserving original dates as intended.

DHCP tricks with Linux network namespace

Some notes from my experiments with fetching more than one IP address from DHCP for same physical ethernet adapter. Nothing too difficult and you don't even need netns for this, few policy route settings would be enough if dhclient (and especially dhclient-script) wouldn't be so broken. For example dhclient has nasty habit of hijacking udp/68 on all network interfaces rather than only those it controls. There's also issues in some cases due routing when DHCP server is not on local LAN but behind WAN like it's in corporate and ISP networks.

Installing Ubuntu 14.04 LTS to Wyse Z90D7 Windows Terminal

I recently posted how to update Wyze Z90D7 to latest available Windows firmware. Which is far from usable. Let's see how Ubuntu works on this hardware. Actual flavour I picked is Lubuntu, but hardware support should be same for all. TL;DR: What a piece of shit this is, don't waste your time just toss it to bin already.

Updating Wyse Z90D7 Windows Terminal from USB stick

I recently found old decommissioned Wyse Z90D7 Windows Terminal. Old BIOS, messed up OS, etc. So exactly how do I update this thing without all those complex management systems and active Wyse support contract?

Crossflashing Huawei B593s-22 from Sonera to Elisa firmware

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.
