The Good News: My untested backup solution worked flawlessly.

Status: My firmware has been failing pre-ship tests since last week. Weird, random, failures.
I've just caught the hardware in the act of glitching out. The 3v3 rail at the processor becomes 726mV in just 7ns (and then rings back nearly as quickly). The poor scope did not want to trigger on something like that.
I did not design this, but I can see that it just needs some more (and more local) decoupling to fix it. Shoddy workmanship!

You don't use EXT4?

I'm required to use a corporate image which uses XFS. The few server VMs I managed to slip past the bureaucracy that are not Red Hat with XFS booted right back up as if nothing bad had happened. The Red Hat ones, well, I had to do a disk-level restore from last Friday's image to get them going again.

We use EXT4 here for our clusters, and I've never seen file system corruption, even when STONITH triggers a kill

I don't know what the rationale is for using XFS but I'm definitely not impressed. This was a middle-of-the-night power outage that occurred on the weekend, many hours after all employees were gone. These servers were idle, they'd been idle for a long time, and yet they still had enough unwritten disk changes to die a terrible death on power loss?

Do you have an intern who thought "all those small capacitors in parallel is a waste, I'll just put a single big one instead", by any chance?

'Fraid it isn't a feature anymore. They've cleverly rescinded that responsibility away from them - Start menu (along with Settings, etc.) is considered an app. And apps are... well, allowed to break. We're sorry for the inconvenience. The matter is under consideration.Yeah, I just had Settings crash 3x in a row (b18323 preview). When the OneDrive shit finally updated itself - cause, ya know, it has to be pushy at the top of the settings window now too, Settings finally stayed up. And build 18329 is updating...

Status: Awake far too damn early because the cat decided that 6AM was the perfect time to demand attention, and did her "rub the face on the hooman's hand to try and demand pets, and when that doesn't work because he's asleep, start doing play-bites" thing.
Gonna try and sleep for another half hour or so before the alarm goes off...

Status: Discovered why my download code was occasionally dropping packets, or rather that that was why it was getting corrupted UDP packets. One router wasn't being dynamically reconfigured correctly, and was thus saying “drop anything I can't send now” instead of “buffer anything I can't send for a few moments”. All because that was on the routing path, but not actually acting as a data download endpoint. Net result? Whenever the bridge-to-UDP node stopped to send things on over the internet to me, the upstream router would start throwing away a random selection of data and corrupting the data stream.
God fucking damnit!
Oh well. At least it only took 2 hours of head scratching and hair tearing to find this… since the previous problem I had in this class of trickiness was a week to diagnose (and half a week to fix due to the large amount of extra model code that needed to be written, alas).

It's a tight board and I guess they thought 'putting caps on each Vss/Vdd pair is a pain, I'll just do one'. di/dt and and the trace inductance for those pins disagreed with them.

Shower thought: we need a thread around here about Indian software devs and the associated WTFs that is as mainstream as the official status thread. It just dawned on me today I cannot go to any one here with my problems cos most of em are your typical cargo cult programmers Indian edition. SMH. Today is a very sad day. Fucking nincompoops.

The
Processes
tab might give a clue. Or might just attribute it effectively to “the kernel” or “a service”. If that's the case, I'd estimate that the former would indicate either something with networked filesystems or someone with a dumbass AV config, and the latter is likely Windows Update. (It's always Windows Update, just as it is never lupus.)

As they said. And there's the Lounge if you want to a little more private (it's set to not let google index). A number of folks post stuff that might dox them out here.

It's reportedly pretty high.
It doesn't follow from there that avoiding your spellchecker will reduce anything, though.

Something appears screwy here but it's beyond understanding at the moment.

Not too much. Most words are probably spelt correctly and so are handled by a simple hashtable search; a full dictionary for English fits trivially in a modern computer (provided you're just putting the words in, not the extra metadata that makes a real dictionary). That which isn't can probably be handled through a bayesian network (held per account).

But since it's Google, it's likely that every transposed letter corresponds to a terabyte of data about the favourite brands of people who type

So most electric scooters go at ~25km/h, assume 20km/h due to traffic lights and other stops, that would mean ~20 minutes to do the 6.5km I have to do to get to work.
Now if I were to buy a motorcycle, which can go a lot faster, it would just take... let me check Google maps... "16 - 35 minutes".
Oh. OK then
-
@anonymous234 Or you could get a bicycle, still take ~20 minutes to get to work, and not have to spend as much time or money in the gym.
-
@PleegWat I tried bicycle. It's uphill half the trip, so it took me 30 minutes to do just that part.
An electric bicycle would work too but... costs about the same as a cheap motorcycle. Although I could still use the bike lane. Might be worth the price!
I could buy one of each type, try them, then return the other two.
-
@anonymous234 Yeah, if hilly terrain is a thing that counts against bicycles. I tend to forget that since around here a 6m overpass would be a large height difference.
