I got a Toshiba T1200, which has a bad screen, and a dead CMOS battery, and I thought the hard drive was broken too...

 but I rebooted it and heard a KTHUNK and a really loud spin-up noise and holy shit, the hard drive works!
and it still has files on it. the newest date is January 1994.
It's a 21mb hard drive, with ~37k of bad sectors.

This fucker is never going to spin up again, so I better go find some serial cables and copy shit off now.
The backlight is fucked so I'm shining a flashlight on it.
without it, it looks like this.
FastLynx has a cool mode where you can use it between two DOS machines and you only have to install it on one of the machines, it bootstraps itself over the serial port to the one without it.
dang it. They're communicating enough to bootstrap, but not enough to actually work in fastlynx mode
ah-ha! It's this "Serial Accelerated (7-wire) Mode".
Turning that off makes it work.
COPYING! starting on the most useless files
I stopped it and reconfigured the serial port.
even with only 21mb, 9600 baud is way too slow
huh, gnu manuals? didn't expect to see that on a DOS machine not touched since 1994
and it's done copying! you can go to your rest, poor old hard drive.
the next computer I'm gonna work on is... another T1200!
This one is fully dead. No error blinks, nothing.
It's a surprisingly simple machine inside. Not super-cramped like a lot of portables.
it's got a cmos battery and a little speaker over here
Which is weird because the system has another battery over here.
neither of which are the main battery!
This one is also the same sort of setup where it's a floppy drive and a hard drive.
You could also get this in a dual-floppy model.
This little add-on here is the hard drive controller.
This was a weird thing. It kinda looks like it'd be a trackpad but it's on the bottom and this machine has no trackpad.
Turns out: it's RAM!
The whole motherboard
The floppy drive is by Toshiba, it's an ND-352S-A, or FDD4271G0W, or even a JAH1058939.
And it looks like a normal floppy drive but it's got the wrong connector. 26-pin IDC, for some reason.
The hard drive is even weirder.
It's by JVC! Yes, that JVC.
It's a JD3824G01-4.

And it has NO DEFECTS, woo!
And it turns out it uses the same 26-pin connector as the floppy drive.
the bottom of the hard drive is interesting
It's some kind of self-parking system.
This one also has something not in the other one:
A modem add-on!
The bottom.
That chip has an interesting pinout.
The sides have 10 pins, but they're arranged as two sets of 5, with a gap.
It's an HD637b05v0f, which is an 8-bit Hitachi microcontroller
Anyway I was hoping to combined these two into one machine, maybe even image the other hard drive?
But sadly I can't get machine 1 to power on anymore.
So I currently have two dead machines.
and I think that's all I'm gonna work on for tonight, so I'll have to hopefully pick this up some other time.
I have a third one in storage, but it makes these two look like they're in good shape
ooh, found a service manual:
https://t.co/E1I5AAzVuh
BTW a fun thing about this system is that the back of the power supply has two power switches.
One of them is for the system, and the other one is for the hard drive!
you can seriously boot up the laptop with the hard drive turned off. it's amazing.
also it has a function called "hard ram", which is why it has so many batteries.
You can set it up so that the expanded RAM is battery-backed, so you can set up a ramdisk that is maintained while the system is off.
Annoyingly the service manual doesn't explain the floppy or hard drive connectors.
It explains random pinouts for things like the display controller, but no hard drive/floppy pinouts.
oh neat. u/ConventionalMemories on retrobattlestations has built a CF-card adapter for these laptops, but it plugs into the expansion slot instead of the hard drive port.

An interesting set of games that I've been vaguely interested in since I was a kid, after seeing one at a friend's house and never being able to find it again, was the BATTLES IN A DISTANT DESERT/BATTLES ON DISTANT PLANETS series.


These are turn-based wargames for windows 3.x, sharing the same engine.
Battles in a Distant Desert is from 1992, and is based on the first Iraq war (Desert Storm)


and Battles on Distant Planets is from 1991, and takes place in SPACE!
I'm pretty sure this is the one I played as a kid.


They've got 3 options to play with:
* Player vs. Player
* Player vs. Computer
* Computer vs. Computer

So it's a 0-2 player game!


They also did a DOS strategy game called "STARDATE 2140.2: GALACTIC CONQUEST" in 1990, but it seems to be lost.
All the games share an experimental AI system based on neural networks.

I went looking for a remote-controlled power switch (the wireless christmas kind, not the modern IoT kind) and didn't find it, but I did find this thing I bought just to figure out why it exists.
It's a timer outlet, but you program it from your phone... but it's not wireless.


Yeah instead it plugs into your phone's HEADPHONE PORT


I got it on sale.
probably because iphone dropped the headphone port and they had to get with the 21st century and make it bluetooth


So inside the box is the device. it's got a little 2-prong polarized outlet with no ground.


on top is the only controls: on/off/timer.

Everyone likes to forget this episode just because it's terrible, but we were really sleeping on inherent comedy in a unfreezing an investor 300 years in the future and having them discover we've transitioned to a moneyless post-scarcity utopia.


it's like a classic twilight zone episode.

in fact, it IS a twilight zone episode.
The Rip Van Winkle Caper, Season 2, episode 24.
Four criminals steal a million dollars of gold bars, then put themselves in suspended animation for a hundred years to hide from the law.

they wake up, then start killing each other from mistrust, then the last one dies in the desert, as he offers a gold bar to the driver of a passing car, asking for water and a ride into town

the confused driver walks back to his car with the bar, and his wife asks what the gold bar is.
he says something like "It's gold... they used to use this for money, before we figured out a way to manufacture it."
He tosses it away, and drives off.

So a weird thing about ultraviolet light, like blacklights and UV-C disinfecting light, is that it's invisible. Kinda. And also Kinda.

See there's a distinctive look to blacklights, they look like this.


But it turns out this isn't the ultraviolet that you're seeing.
See, the light produced by the bulb isn't perfectly monochromatic UV. Blacklights are in the UV-A range, which is 315 - 400 nm. The human vision range is 380-nm to 700nm.


There's a little overlap there, between the high UVA and the low end of human vision...
And there's multiple types of ultraviolet lights, but the kinds used in blacklights peak at 370nm or 340nm

so while most of the light coming out of the bulb is in the invisible UV range, some of the light is a bit higher up in the spectrum, which makes it slightly into the visible violet range.

So the light you see from UV lights is either the not-UV light it produces as a side effect, or something else fluorescing.

Something that I didn't realize but hurt my brain to learn:
John Norman (aka John Frederick Lange Jr.), of the Gor series of sci-fi/BDSM novels, is still alive.
He released two books (one of them a Gor book, #35), in 2019.


I guess with the fact that the series started in 1966 and feels like it's always a historical thing... I assumed he had to have quit writing and/or died back in like 1986.

Nope. Still alive, he's 89, and was apparently still writing as of 2 years ago.

also, my brain being what it is, I totally just googled for the book's cover image by entering "trans man of gor" which is NOT the title.

in my defense, how many book serieses look like this WITH THE SAMEAUTHOR FROM BOOK #1 to BOOK #35?


Anyway if you look at any this and think it's a suggestion that you should try reading any of these novels or learning anything about them, you are quite mistaken.

Gor is bad sci-fi and bad BDSM, and you should skip it for either reason.

The first area to focus on is diversity. This has become a dogma in the tech world, and despite the fact that tech is one of the most meritocratic industries in the world, there are constant efforts to promote diversity at the expense of fairness, merit and competency. Examples:

USC's Interactive Media & Games Division cancels all-star panel that included top-tier game developers who were invited to share their experiences with students. Why? Because there were no women on the

ElectronConf is a conf which chooses presenters based on blind auditions; the identity, gender, and race of the speaker is not known to the selection team. The results of that merit-based approach was an all-male panel. So they cancelled the conference.

Apple's head of diversity (a black woman) got in trouble for promoting a vision of diversity that is at odds with contemporary progressive dogma. (She left the company shortly after this

Also in the name of diversity, there is unabashed discrimination against men (especially white men) in tech, in both hiring policies and in other arenas. One such example is this, a developer workshop that specifically excluded men: https://t.co/N0SkH4hR35

What happens when a skill you have becomes obsolete? No, this isn't a R vs. Stata thread---it's a thread about a working paper w/ @sonnytambe!
https://t.co/w6nLf1tnST


The skill we look at is Adobe Flash, which @apple decided to no longer support back in 2010, which in turn caused demand/interest to plummet, as measured on @StackOverflow and in online labor markets, one of which is our empirical context


Despite the big fall-off in Flash jobs posted, very little else appeared to change in the market for Flash skills: wages for Flash jobs didn't fall, jobs didn't become easier to fill & openings weren't inundated with out-of-work Flash programmers


What happened was that (a) new entrants stopped specializing in Flash and (b) at least some existing Flash specialists started moving to other skills. In short, the demand shock quickly became a supply shock


At the level of the individual Flash worker, using a matched sample, we find (a) no fall-off in their wages, (b) some decline on-platform hours-worked. The most-focused on Flash workers had substantial increases in application intensity and a movement towards new skills

The vast majority of images are jpegs, which are internally 420 YUV, but they get converted to 32 bit RGB for use in apps. Using native YUV formats would save half the memory and rendering bandwidth, speed loading, and provide a tiny quality improvement. It would also be \

a good path to supporting better video codec still image formats and 10 bit components. You can do it today, but you need to do the color conversion manually in a shader, which can be a big ask for some devs. Defining a FMT_JPEG_YUV that does driver injection akin to the \

external image support on Android could make it much more of a drop-in. Even doing it the hard way seems like it would be worthwhile for web browsers today.

Last up in Privacy Tech for #enigma2021, @xchatty speaking about "IMPLEMENTING DIFFERENTIAL PRIVACY FOR THE 2020

Differential privacy was invented in 2006. Seems like a long time but it's not a long time since a fundamental scientific invention. It took longer than that between the invention of public key cryptography and even the first version of SSL.


But even in 2020, we still can't meet user expectations.
* Data users expect consistent data releases
* Some people call synthetic data "fake data" like
"fake news"
* It's not clear what "quality assurance" and "data exploration" means in a DP framework


We just did the 2020 US census
* required to collect it by the constitution
* but required to maintain privacy by law

But that's hard! What if there were 10 people on the block and all the same sex and age? If you posted something like that, then you would know what everyone's sex and age was on the block.

Agastya Muni & Kaveri River
#story
This is a story which describes how River Kaveri was brought on earth by Agastya muni. There was a king named Kavera lived in the Brahmagiri hills who prayed to Brahma for a child. He was blessed with a daughter whom he named Kaveri.


Agastya muni married her. A demon, named Shoorapadma, wanted to trouble people so he prevented rain from reaching South India. As a result famine occurred in South India.
Agastya Muni who came that way was very sad seeing this. He started to pray Mahadeva for a solution.


Shiva gave him small amount of Ganga water in his Kamandalu (small pot) and said wherever you spill this water the river will flow from there. Agastya Muni travelled lot of places to find a suitable place to pour water. Feeling tired he kept his Kamandalu and took rest.


At that time Ganesha took a form of crow and perched on the Kamadalu and made a hole that water began to flow as river Kaveri. This place is now called as Talakaveri (Karnataka), located in the Brahmagiri hill.


Tala Kaveri has temple for Agastheeswara, which denotes the story between Kaveri and Agasthya muni. Kaveri is a part of Ganga, thus, also called Dakshina Ganga.

The p@stor slowly began to study the house and he learned that the boy's grandmother was the most influential person in the house. So he thought 'Corrupting the grandmother's mind can make the whole family Xtian as well as the whole village.

She spoke of Rama setu where stones floated in sea just by writing his name on the stones and that they are still floating today.
The p@stor continued his efforts but all his tricks went in vain.

One day he had brought a cake from the church and he thought of offering it to grandmother but he was doubtful that she would eat it. But contrary to his expectation, she took the cake and ate it.

IT WAS RISHI KANADA WHO GAVE THE ATOMIC THEORY & TALKED ABOUT THE GRAVITY OF EARTH, 2600 YEARS BEFORE AN APPLE FELL IN FRONT OF NEWTON'S EYES:

Scientists of the modern world credit an English scientist John Dalton (1766 CE -1844 CE) for the Atomic Theory.


And this is because, most of us are not even aware of an ancient Indian Sage named Kanada, who was the first to formulate the theory of atoms, almost 2600 yrs before Dalton and talk about earth's gravity.


Rishi Kanada was born around 600 BCE in Dwarka, Gujarat and he was the son of a philosopher named Ulka. He was fascinated with the minute detailing of the things right from his childhood. Once, when he was very young, he accompanied his father on a journey to Prayaga.


He saw plentiful grains scattered along the path leading to the shore of river Ganga. It's a tradition in Hindu families to scatter the grains for the ants and birds to feed on them. Suddenly, an ant caught his attention, who was feeding on a rice grain.


He was mesmerised by this very fact that how a small grain of rice becomes food for the ant but to satisfy the hunger of a person so many grains are needed together. This incidence made him realize the importance of a single grain of rice.
