+andrew mcmillan​ finnish libraries moving to koha
 ·  Translate
Useat maakuntakirjastot ovat ottamassa käyttöön avoimeen lähdekoodiin perustuvan Koha-kirjastojärjestelmän. Oulussa toimintaa pidetään vallankumouksellisena. Edelläkävijä Joensuussa kokemukset ovat rohkaisevia. Koha on Uudessa-Seelannissa kehitetty järjestelmä, jota käytetään kirjastoissa ympäri maailmaa, mm. Oslon kaupunginkirjasto on päättänyt ottaa Kohan käyttöön. Suomessa edelläkävijä on Joensuun seutukirjasto, joka otti Kohan käyttöön jo vii...

Riku, I was stuck in the Wikimedia stand during basically the whole FOSDEM. And I could even say properly Hi! when you came. Anyway, next time. I'm very happy to see that you keep working on the cutting edge.

Peter Maydell on rr: "Being able to follow the chain of causation backwards from the failing assertion to the exact point where things diverged from your expectations is priceless"

NVMe looks like step into right direction. However, looking at the linux nvme driver, it seems NVMe exposes a just dumb block device. The blocks are of course stored to an undocumented filesystem implemented by proprietary firmware.

Of course the vendors prefer this way. Dumb interface lets vendors add value" on top of the bulk NAND flash by creating a slightly better write distribution algorithm than competitors - never mind the bugs in corner cases outside NTFS usecases...
 
This is the first time I see NVMe in a consumer product, hopefully it will replace AHCI based SSDs in all new products soon.
