What is the monstrosity of a connector on the end of the cable? It looks like combination of B and Micro-B female sockets.
-
@Bulb It's a USB 3.0 B connector. One of many things wrong with this picture.

One of many things wrong with this picture.
Why is there even a USB port on the underneath pointing forwards?
-
@loopback0 If you look along the upper edge of the keyboard you may notice what looks like a battery hatch. Should give you your answer.
-
@Atazhaia Was it designed by the same person who did the Apple wireless mouse?
-
@loopback0 It is a wireless keyboard, yes. It does not have rechargeable batteries. Or any socket to plug any cables into whatsoever actually. It does however come with one of those wireless dongles to plug into a USB port on the PC, and as with all wireless keyboards and mice with dongles there tend to be someplace to stick it when not connected to a PC...
-

Oh that makes more sense.
-

Do you happen to know where that is?
inb4: that's the cable. the lack of ferrite chokes expose its true function as an antenna
-
@kazitor I do not know where the dongle belonging to that specific keyboard is, the owner isn't using it. She just brought it to me when I needed an external keyboard to try and fix a misbehaving laptop. The cable is the one that connects the USB hub of our monitors to the PC. I really do not know why it was stuck into the keyboard and I dare not ask...
-

It's not wrong only in the picture. The connector looks like the designer was eating a very special kind of mushrooms (well, the designers of the original ones apparently did as well; only C approaches sensible).
-
And at home I got a USB hub that has a USB 3.0 Micro B connector. Which looks like a USB micro connector with a conjoined USB micro twin. I understand why they do that, it's so a regular USB (micro-)B connector can be connected into the USB 3 socket too, just they can't connect to the extra pins which are in the extended bits.

Got a ticket from my main tester, who should know better:
When executing
feature x
it doesn't used the saved parameters.
I tried that and it worked. Please provide an example that doesn't work.
It doesn't work for anything saved before we upgradedfeature x dependency
.
I tried these two examples and they worked fine. Please provide an example that doesn't work.About ready to close the fucker.

I don't doubt that she witnessed the issue she reported. But there's no log trail or anything here so I need something I can use to reproduce. There was another ticket that hung around like this. I explicitly asked her, "What data did you put in?" In this case, there was a log trail, but she never told me what the fuck she entered to get the result, and I could never reproduce the problem.

I've spent all yesterday setting a device to write core dumps over NFS to the build server it is attached to (install nfs, rebuild image for the device, wiggle the options until it actually connects etc.—because the internal space is too tight for it). I've spent all morning running the tests, but they didn't crash. Then I got to the point one did—and it didn't generate a core dump anyway.
That's because the framework registers a signal handler that writes some info (ok), but then instead of re-raising the signal for the default handler it terminates with
_exit(1)
. So core dump does not get generated and systemd does not know it crashed. But they do have a script to enable core dumps. That obviously doesn't work.

Aside from looking doofy, it's actually a pretty good design for backward compatibility.

I needed to look for a deposit in my online banking. I go to the account and I see an option to sort by deposit, which brings all of the deposits to the top of the list. I discover that doing so does not show the balance when that deposit was made, but instead the math on running balance is evaluated just the same as if it were ordered by date, meaning that all debits are done first and then deposits are added back in, from top to bottom.
It would take a person a little while to pay off such an overdraft, if that were actually the case.

Speaking of which - can someone explain to me how USB 3.0 A connectors achieve backward compatibility? Are there retractable pins in the socket or something?

@TimeBandit I'm looking at the back side of the socket, right? I think I see it now. Thanks!

Gamers, probably. They need to press keys super-fast, don't you know?
-

Yes, the 3.0 pins are further in the back, so only the 3.0 plugs will reach them.
Also note that 3.0 has 5 pins instead of 4.

Aren't the 3.0 pads at the front of the socket and the pins at the back of the plug?

I see this type of thing the Q&A section on Amazon product pages all the time. Question: "Hey, does this product do such-and-such?" Top Answer: "I don't know, I don't own this product."

What, is someone going to type at 5Gbps and they need 3.0 speeds?
OMG, haxxor keyboard spotted...
How else is NCIS going to function?

Depends on how the developer set up their depots and folders. For some apps, the content that's in the demo isn't in the main depot but a separate demo depot that's also included in the main game, and uses the main game's install folder. Other developers don't bother.

It's 2019. Why is it so hard to print exact value of a double without truncation, without scientific notation and without unnecessary trailing zeros?

In decimal? Because
DBL_MAX
is something like a number with about 300 necessary trailing zeroes. AndDBL_MIN
one with about 300 leading zeroes.

A double. Not a result of division of two doubles.

There's technically a Hypatia Demo. It's exactly the same size as the Full Version though, so it's kinda pointless to download it...

The "exact value" of a double-precision float is truncated, to 53 significant binary figures. And they don't play well with decimal, unless you really want to see 0.09999999999999999167332731531132594682276248931884765625, in which case I've been semi-working on something just for you!

Division of two doubles... is a double!

The value that gets printed by any sane conversion is a lossless representation of that value. The amount by which it differs from the stored representation is too small to end up being stored.
