Comment Re:It's all dark arts anyway (Score 5, Interesting) 74

Often such variation just means inadequate controls. Many years back, I was working on some code for atomic clock calibration. The results were consistent M-F, but wacky on weekends. Turned out, there was a parking lot close to the lab. Full of cars, the clock ensemble behaved one way. Without all that metal hanging about, it behaved quite differently. Placing a Faraday cage around the entire lab did the trick (adjusting the calibration sw would have been much cheaper, but such is life).

I don't know enough the specifics of the testing under discussion ... but when measuring really small things, and getting consistent results is elusive (and incredibly tied to test conditions) my experience says we haven't properly identified all the critical variables, and they aren't being controlled.

Encrypted "home" disk, and yes, I shutdown when taking my work laptop offsite. If it should get stolen, I don't want to make anything easy for the crooks. Ditto for personal laptop when going on a trip (not so much for moving from coffee shop to home ;>).
With SSD based systems, bootup isn't *that* much slower than "wake from sleep" with harddisks ... so I indulge my inner paranoia.

Comment Re:Scientific Linux and CentOS both RHEL (Score 2) 94

https://www.scientificlinux.or... explains the history and rationale. I think your analysis (which has been equally true for a few years) is probably spot on which is why they are cancelling future work. Funny that the SCL site doens't mention this critical future info. I'd have thought they'd tell their community first and the press second.

That said, one can image the Fermi (and possibly Cern will rejoin) might have a repo of their own with suitably patched compilers, schedulers and other fiddly bits which might have specialized fixes/hacks/workarounds for large ensembles doing scientific computing. But doing an entire distro has been overkill for some years (probably since 2014+ when RH brought CentOS back in-house.

Given Apple's continued work in chip design, along with the existing pool of chip design talent in Texas ... I'd have guessed more than 25% would be locals (if not born in Austin, already present, educated, and employed ;>). Sounds like a good move for Apple, and good for Texas as well.

About 4 years ago I started biking to work on an ebike. My commute was a hilly 7miles (1 way). What had been a 15 to 30 minute commute became a 20 minute workout). Now my commute is closer to 13, and I do it in under an hour. My schedule can accommodate an hour long commute...especially since it doubles as a workout.

Or at least seriously suboptimal. Instead of flying empty planes, Heathrow should charge a "non-usage fee" which is a few thousand dollars less than the "ghost flight" costs.

More or less cost neutral to the airline; raises some income for Heathrow ... and saves the jet fuel, wear and tear ...

Comment Really our worst move? (Score 1) 163

Unless AI robots get vastly more flexible rapidly, seems to me that large armies of nasty humans are still a much bigger threat (albeit one we've lived with since time immemorial).

But I suppose in the end, folks think really clever, self improving robots will win the day: https://en.wikipedia.org/wiki/...

Years ago Bill Joy warned everyone about self replication ("grey goo"). Self replicating *and* self improving seem like much worse ideas than simply arming them.

Use case; Consider some sort of waste repository (nuclear, biologic, something really, really bad to let free..zombie virus perhaps?). Say we've designed the facility to last for thousands of years. Folks have already worried about what happens when the language is no longer known, etc. ... would a "killer robot" as a last line of "defense" be worse than allowing the genie out of the bottle?

English is seldom as precise as we programmers would like to make it. "Bread" is defined as "flour, water and yeast" ... but various breads are made without yeast ... and bread is used generically for food (dating back to hebrew/biblical usage), not to mention using the term to describe money.

Given that the various soy and nut milks have been in use (and named) since the 13th (other sources, 17th) centuries, it seems to me that the horse left this barn a long time ago.
