@silmeth That's how I feel about #KDE's notification area. I do *not* appreciate UIs suddenly appearing under my cursor or in the place where I'm reading.

So... what is a "push notification"?
I heard this term in mainstream media, so I'm interested in a non-technical definition.

https://www.ibm.com/think/topics/push-notifications

IBM says that it's a popup from the OS, but it tracks them only to 2008, whereas "Activate your Windows XP" popup existed back in 2002, so IBM's definition contradicts facts.

(IIRC There were already IM messages in popups, "your download completed", etc.)

What does it actually mean? Is it different from "notification" or is it only marketing?

How do I modify builtin #Javascript objects?
In #Firefox I can do:

Object.defineProperty(window, 'performance', { value: undefined });

but if I put it in #Greasemonkey it does nothing :(

Finite Element Analysis rabbit hole.

#PrePoMax works passably on Linux and with youtube tutorials (thanks Indian- and Polish-accent guys) I could actually simulate twisting a rod and do experiments. Easy to use for a total newb!

That informs me where to place strain gauges for one of my projects.

I promise all the random stuff I've been doing ties together, eventually.

What's a good #format to serialize simple structured #data in an efficient way?

I'm thinking about some binary #XML encoding. Also, #ASN.1 because it natively uses integers, not just strings. Is the packed representation (PER) widely supported?

The data will be a bunch of interleaved time series streams, so variable field lengths could be a big win.

Is there a format for stuff like that?

Great #fiberoptic workshop by @karotte !
1. Strip the #fibre
2. Place in the splicing machine.
3. Watch it display the FAKEST #hollywood impression of "MERGING NUCLEAR CORES" ever, complete with a nova of light in the critical moment. Only lazor sounds missing.
There's no way this is a real microscope display.
Seriously, people deserve to see that jank :P

How much do #Python clocks progress in "60 seconds"?

CLOCK_BOOTTIME 60.6
CLOCK_MONOTONIC 60.6
CLOCK_MONOTONIC_RAW 56.0
CLOCK_PROCESS_CPUTIME_ID 0.000952
CLOCK_REALTIME 60.6
CLOCK_TAI 60.6
CLOCK_THREAD_CPUTIME_ID 0.000952

Only CLOCK_MONOTONIC_RAW is tracking the hardware #clock correctly.

So if you actually want to measure #time accurately, use that one.

@harryomvlee @tompearce49 So you mean that you can travel an infinite distance once given a push, just a car will go slower. Gotcha.
