Keybort

This one is a MicroWeb Touch-1 XT/AT. Kinda.

See if you look up that keyboard you find the Deskthority page on it, showing this.
It's clearly pretty similar, but there are some differences.
Also that one uses a PC/XT/AT DIN5 connector, and this one uses some kind of RJ connector.
This one isn't in the greatest of shape, but considering I got it from the Chuck Colby estate sale, it's surprising it isn't completely water-damaged.
It's got some minor rust damage inside, where the metal clips rubbed off on the PCB.
And the control chip is a C35331E.
It's one of those chips you can find a few places that'll sell you one, but nowhere has a datasheet.
"8647" is probably a date code? 47th week of 1986.
That matches the chip on Deskthority.
And all keycaps removed! These are "Futaba MA series" (aka Futaba clicky switch) switches.
It's got 5 pins connected. AT is only 4 pins, but the PC/XT keyboard is 5 pins. So maybe this is a switchable keyboard?
the Deskthority wiki seems to partially agree with that:
There's a jumper under the tab key, which is theorized to be a XT/AT switch.
SO, what the heck is the pinout? I have no idea what the pinout of the IC is, and nothing to connect this to to spy on it, and no results online for googling the name other than the one that's shown up on deskthority.
Well, the PCB has two other chips on it.
They're both 74-series logic.
We can easily find datasheets for those and they should be sharing power/ground.
green is +5V
and either blue or yellow is GND.
(they both seem to be ground, at least as close as my multimeter can tell.

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

Legacy site *downloads* ~630 KB CSS per theme and writing direction.

6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices

PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.

735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
1. One of the best changes in recent years is the GOP abandoning libertarianism. Here's GOP Rep. Greg Steube: “I do think there is an appetite amongst Republicans, if the Dems wanted to try to break up Big Tech, I think there is support for that."

2. And @RepKenBuck, who offered a thoughtful Third Way report on antitrust law in 2020, weighed in quite reasonably on Biden antitrust frameworks.

3. I believe this change is sincere because it's so pervasive and beginning to result in real policy changes. Example: The North Dakota GOP is taking on Apple's app store.


4. And yet there's a problem. The GOP establishment is still pro-big tech. Trump, despite some of his instincts, appointed pro-monopoly antitrust enforcers. Antitrust chief Makan Delrahim helped big tech, and the antitrust case happened bc he was recused.

5. At the other sleepy antitrust agency, the Federal Trade Commission, Trump appointed commissioners
@FTCPhillips and @CSWilsonFTC are both pro-monopoly. Both voted *against* the antitrust case on FB. That case was 3-2, with a GOP Chair and 2 Dems teaming up against 2 Rs.

https://t.co/TgNblNSCBj – here is why the same applies to Product Management, too.


There is no better way of learning the craft of product, or proving your potential to employers, than just doing it.

You do not need anybody's permission. We don't have diplomas, nor doctorates. We can barely agree on a single standard of what a Product Manager is supposed to do.

But – there is at least one blindingly obvious industry consensus – a Product Manager makes Products.

And they don't need to be kept at the exact right temperature, given endless resource, or carefully protected in order to do this.

They find their own way.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.

https://t.co/FBfXhUrH5d


Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.


...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.


Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
