Backt mehr Brot!

Vor genau zwei Monaten erschien in der Podcastreihe “CRE – Technik, Kultur, GesellschaftFolge 213 zum Thema Brot. Brot? Ist doch irgendwie langweilig. Kauf ich im Supermarkt. Mag ich gar nicht so gern. Kann man keine drei Stunden Sendung von machen.

Kann man doch. Mit Lutz Geißler vom Plötzblog spricht Tim zwei Stunden und 55 Minuten lang über Brot und hat auch direkt den Nachmachwunsch in mir geweckt. Der erste Versuch für ein Anstellgut verlief vor ein paar Wochen leider im Sande. Hab es einfach vergessen. Aber nachdem Freund Julian (den der CRE auch animiert hat) mich mit bereits präpariertem Anstellgut ausstattete, hab ichs dann hinbekommen – und heute das erste Mal gebacken. Ein Konsumbrot nach Bäcker Süpke ist es geworden, was man bei uns wohl Graubrot nennen würde.

Properly granting access to datasets in Jails and Plugins on FreeNAS

Recently I wanted a FreeNAS plugin (which are running inside FreeBSD jails) to access data on my storage pool. Reading is generally less of a problem with the default settings but when it comes to writing, problems may occur. By default, my media datasets are running with 775 permissions, therefore:

  • The owner can read-write-execute
  • The group can read-write-execute
  • Others can read-execute.

The owner is janwillhaus, since I do all the management of the data and don’t want to run around sudo-ing all the time. The group on the other hand media, which may contain any other user that requires write-permissions to the files. All other users can at least read the files and that is fine.

Finally some peace of mind: my 2016 storage and backup setup

For many years I have spent quite a lot of time figuring out ways to savely store my data. Many iterations have past by now, but recently I have finally reached a stage that is worthy of talking about.

For a few years I have been running a decent homeserver (a.k.a NAS) handling the heavy lifting when it comes to mass storage. The machine is fairly powerful for what it does; a Xeon E3-1230 v3, 16GB of ECC RAM, and 9TB of raw storage configured as a ZFS pool running in RAIDZ1 (meaning one drive may fail and the pool can still be rebuilt—the superior RAID5 equivalent in ZFS). The server mostly handles SMB shares in my local network. I am not good at deleting stuff, so I rather push stuff from my “daily driver” down onto the NAS to free up some space while still keeping an extensive archive of all my files.

It’s finally happening: HDD shipments starting to drop massively

It’s finally going down: HDDs are on the decline. AnandTech has a (just as always) thorough analysis of the market in first quarter of 2016 and I see what I expected to happen for quite a while now.

Looking at the data (most graphs on page 2 of the article), there is clear signs that the phase-out of HDDs for consumer products has begun. The declines are almost exclusively happening to the non-enterprise(-ish) products, and that is good. I swapped my last HDD into an SSD about three years ago and have never looked back. Especially when it comes to mobile computing in laptops, HDDs are just the wrong kind of storage. Spinning platters, and moving heads have no place inside of a device that moves just as much.
