Tragically I installed it recently on mac and it "froze up" after awhile. Chrome never freezes for me. I like FF but dislike instability. Maybe it's just me...
I've had count(*) queries take like literally days in Postgres. Want to insert a lot of data? Expect it to cost a lot of RAM. It's got high features but some really rough edges too :|
Depends on the storage engine afair, but both innodb an myisam have either index or global metadata based solution for this. I think in myisam its an estimste if you use count(*) so you need to use count(id) to get an exact value. This is all well documented
count(*) doesn't do full table scan as it's not tied to specific data. It has special handling logic. The only case where it might have to do a full table scan is if you try to count() on a specific (nullable?) column without an index.
Yes I suppose the real question is would those employees "elect" for a 6 hour day with a 25% pay cut, or not...that would give you something of a feeling for whether the benefits out weight cost, as it were...
As mentioned elsewhere in this message, it depends on the job really. Nursing staff in a nursing home might benefit more from shorter shifts. Someone that is sitting at a desk taking phone calls or entering data might benefit from a bit longer of a day.
I'm more in the latter camp and my colleagues and I have been talking about doing 4x 9.5 hour days and just rotating who gets Friday's off vs the rest of the week. I could easily come a bit earlier, leave a bit later and get tons of benefits from 3 day weekends.
I heard once anecdotally that google side projects are sometimes "supposed to be work related" so not quite as free as you'd imagine, FWIW...or perhaps they're not dunno never worked there.
I think they are supposed to be work related, but that's still a change of pace. There are things I want to fix at my job that will never be fixed because it isn't anybody's job, and nobody would let you mess around with it because it would be circumventing the normal decision making process. It would be really nice to just say "I'm just trying something out," without needing to schedule an hour-long meeting with 8 people to create a roadmap.
Ouch. I feel lucky to have enough autonomy I can blow a few hours out of a week "just trying something out" without being grilled why I wasted a few hours over it.
