I did get the Home, Back, Home, Home to work possibly one time a couple months ago, so not sure if the Oct 31st firmware changed something, as I have not been able to do any kind of reset. (tried the Back x 4-5 times as well at boot up, but nothing happens, after power off/unplugging for 1-10 mins). </code> https://h30434.www3.hp.com/t5/Printer-Setup-Software-Drivers/HP-Officejet-Pro-8600-N911g-Firmware-Update-Fails/td-p/7876436 ===== NAS Einführung btrfs ===== Stand siehe Unten - tl;dr: 3x 3TB (500mb efi, 500mb raid1 /boot, 50G raid5 /, 2,7TB /mnt/raid_daten) Einbau neuer 2x 5TB wd red ==== Anlegen der neuen Partitionstabellen ==== <code bash> nas brot # gdisk /dev/sde GPT fdisk (gdisk) version 0.8.10 Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header.

(Or I couldn't come up with the proper keywords for Google). The situation is simple. I have a table where the primary key is some auto-incrementing ID number (in the case of postgresql, with the primary key called nid, the definition is nid serial primary key). After inserting a record into the table, I want to know what ID it has got. Turns out it's very simple. I need only to pass a custom seqname to db.insert(). nid = db.insert("tablename", seqname="tablename_nid_seq",...) For the serial column, postgresql creates a sequence automatically and assigns it a particularly constructed name. More details at FAQ: Using Sequences in PostgreSQL. This is probably not the best style (I'm hard-coding the seqname in the source code), and I'm not even sure if it's the right way. But at least I can proceed with my prototyping and hacking now :) http://blog.zhangsen.org/2011/07/webpy-get-auto-increment-value-after.html notes_brot.txt Last modified: 2021/01/31 23:04by brot
