Plain text passwords, seriously. At that point, I'm not sure what would be a similarity with any other engineering profession. The plain text passwords are beyond any rhyme or reason... and then returned to the end user client. If anyt

I doubt, as that would break any FileChannel.write(ByteBuffer) that expects the buffer to be consumed (remaining()==0) I suppose it's possible to create a new set of API or augment the existing ones not to use thread pool, still rather

"An AsynchronousFileChannel is associated with a thread pool to which tasks are submitted to handle I/O events and dispatch to completion handlers that consume the results of I/O operations on the channel." This part i

No idea why the personal involvement with valve pumping has come from. Atari "VCS All-In Bundle" is debian based, too. They are not playstation popular, of course. Like mentioned "no love for consoles", dont own one, not

This feels like calculating a "spherical horse in a vacuum", except with drag this time.

Still need a major supplier both the laser emitters and esp. the optics. The weapons will be a lot more expensive compared to conventional weapons, or any anti-riot weaponry. Aside the sci-fi vibe, I could imagine James Bond esque - still q

True but how would you deploy high powered ones and keep line of sight?

The application would be more civil than war-alike, if it existed.

by xxs 3y ago
They are called direct energy weapons, more like a sci-fi, though. It'd be a rather short range weapon, that's not easy to aim, require a line-of-sight, can't penetrate armor... or goggles, or fog/dust.

Agree on the 3 orders of magnitude difference. 40W soldering iron will inflate post-it notes, 40W laser steel/stone engraving/cutting area.

You dont have to look at the laser at all, scattered beam can be dangerous as well. Note: class 4 lasers have no upper bound, they are just hazardous.

It's unlikely they will be able to supply that much current if there are many participants.

LRU is expensive in a way that it doesn't scale (thread/core wise). What I do is probabilistic eviction, e.g. take randomly 17 items - evict the lowest three (need some algorithm for scoring). What I tend to use for scoring is &#x

The VRMs work at 100KHz-1MHz, they are not pure DC. When it comes to "reactance", it's orders of magnitude worse than the well-known 50/60Hz AC.

says 600W GPU, that's 50A. Screw based connectors would do just fine - delivery 48V would require to step it down to some other (sub 20) voltage first. That part would be at the GPUs. Also I do understand how it works.

240VDC conversion to any low voltage (1V for cpu/gpu) won't happen. Most of the copper is spent on carrying hundreds of amps at low voltage not the 12V lanes.

by xxs 3y ago
The GPU runs at 1V (sub 1V usually). The issues with the power delivery and the nvidia connector are their own.

48V -> 1V (for the cpu) would be super extra funny, though. The power stages would need to be high voltage mosfets. No idea if a single conversion 48 ->1V at 400A+ would make any sense. Also the capacitive coupling for 48v is quite mo
