[opensuse] Interesting new feature in Thunderbird 60: global search
by Carlos E. R. 22 Sep '18

22 Sep '18

Hi, I found a new feature in Thunderbird, under settings, advanced: Enable Global Search and Indexer. A new search box appears on the "third" status bar on the top, that says "search Ctrl-shift-k". It took something like two days busy to create the index, then on "enter" it creates a new tab with the finds, and a left panels with data and controls. Per people and per folder sort, per mailing list, per account, per tag... Once the index is created, it is fast locating mails. I don't know where the index is stored, but my global-messages-db.sqlite file is now 760 megs. I also do not know if it can take advantage of server side indexing (dovecot), but I do not have it enabled. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas))

[opensuse] swap performance
by Peter Suetterlin 21 Sep '18

21 Sep '18

Hi, I just had to hard-reset my laptop :( Running some memory-intense application, it started hitting swap. I already then noticed hangs in both graphics display and the music i was playing in background. The application continued to use more memory, when at some point the whole system basically froze. Swap fill was around 60% at that moment. Music started strongly stuttering, after some 30s or so stopped completely. Mouse cursor almost frozen first, still doing some jumps, then also dead. It stayed like that for 9 minutes, then suddenly music started again, display updated - only to freeze again after a short moment (a few 10s). That was the moment I pressed the button. I checked the log. Absolutely nothing mentioned in the journal, no faults or errors. I checked the swap partition. It's on an SSD, and I can read/write at expected rates without errors. WTF is the system doing there? Has anyone seen similar problems lately?

[opensuse] Thunderbird's monthly joke

21 Sep '18

'Would you like to compact your folders? This will save approximately 119MB of space?' Wow! Sure, OK. * a few seconds later * 'Done compacting. 3.8MB saved.' I mean, this little ruse has only been going on for, what, the last 18 years. And I fall for it every time. -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
