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.

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.

Check out what I got today. You can tell it's something weird as fuck just from the box...


So this is a FISK ... thing.
It's a floppy disk fax machine! You can fax floppies to other people who have these things.


Apparently you can connect it to external drives, computers, or printers?


So I'm gonna do more research into this thing and how it works, but while I'm here, some of the other stuff I got today. Some 3.5" floppy disks. Single sided, double density ones! These were some of the very first 3.5" disks and basically nothing used them.


I also got this book: AutoSim, the Marketing Laboratory.
It's some software to help you sell cars, apparently! it was weird and cheap, so I got it. I'll of course image it.

argh chrome updated and it seems they've intentionally broken custom search engines. I have had a keyword search for "foone" which searches my own twitter, so I just type "foone BLAH" and it gives me a twitter search for when I said BLAH, right?


but now I get that option in the titlebar of "search twitter self-search" which is the name of the search"
if I just type "foone blah" now...

it ignores the search I have had defined for years and just googles it.


and this is definitely on purpose because they didn't just break it, they changed it. it's now "fooneblah"


there doesn't seem to be an option to make this stop and get the old behavior back :(

Tomorrow is gonna be fun for anyone in charge of requisitions.

There's gonna be a bunch of SRE teams asking for lockpicks, crowbars, hydraulic rescue tools, chainsaws, and some breaching shotguns

new SRE exercise:
imagine all the digital locks have broken and are keeping you out, and you can't connect in via the network.

how long until you get a console on the main servers?

now figure out how much money you'd lose being down for that long. Multiply out hours-of-downtime by money-per-hour.
There's your budget for designing Creative Solutions to bypass all your security

Although before you go trying to kick down doors:
Remember that doors are secured between the uprights and aren't as easy to smash open as movies might lead you to believe.
But the wall next to the door is probably just drywall and a little insulation.

drywall is also pretty cheap to repair.

Lockpicking Floppies!

I don't know why twitter is refusing to insert a card for this one. In any case, It's the @LockPickingLwyr, and it's a floppy-drive-lock.


so I've been meaning to do a video or thread on these sorts of locks myself. I have several, of different designs.

generally they're all designed vaguely like this one: it's a plastic insert that goes into the floppy drive, then it has some bit that rotates with the key to hold itself inside.

and they pretty much universally use super-cheap low-security tubular locks like this. You can probably pick most of them with a ballpoint pen

you know how Atari called the Jaguar as a "64bit system", because it had two 32bit CPUs? (or because it had a 64bit bus, but let's not worry about that)
we should apply that logic to the current generation of consoles.
So the Switch is a 256bit console. It's the Nintendo 256.

The Xbox Series X? terrible name.
Better call it the "Xbox 512 Blu-ray".
like the Jaguar CD, the Sega CD... the good old days when consoles had their media type in the name.

Boringly the PS5 is also a Playstation 512 Blu-ray, because both of them are using the same AMD Zen 2 CPU.

The Switch one is weeeird. It's built on an Nvidia Tegra X1, which is an 8 core 64-bit CPU, so that should be 512, right?

Well... no. Four of them can't be used. And later documentation doesn't even mention them.

it's some weird system where the system-on-a-chip has four Cortex-A57 cores and four Cortex-A53 cores but only the A57s are usable?

The YouTube algorithm that I helped build in 2011 still recommends the flat earth theory by the *hundreds of millions*. This investigation by @RawStory shows some of the real-life consequences of this badly designed AI.


This spring at SxSW, @SusanWojcicki promised "Wikipedia snippets" on debated videos. But they didn't put them on flat earth videos, and instead @YouTube is promoting merchandising such as "NASA lies - Never Trust a Snake". 2/

I’ve been flooded with Snapchat Spotlight questions after posting I’ve qualified for a payout 4 times. Here are the answers to the most common questions I’ve gotten in my DMs. These answers are my own experience and may differ from others .

Q: How will I know if I am getting paid?
A: You will get a message from Team Snapchat that looks like the below message 2-3 weeks after the snap has gone live. At this point it important that you verify your email address.


Q: How long after I’ve been notified I qualify, will I know for how much?
A: my experience is that usually 7-10 days after you get the qualifying message, you get a message with the amount, it will look like this. This message will include a unique access code for HyperWallet.


Q: How do I set up my HyperWallet?
A: Around three weeks after you get the payment amount you will get an email to your verified email from Snapchat Pay. It will look like this and will require you to fill out some tax forms, takes like 10 min.


Q: How long does it take to actually get the money in my account?
A: it took me like 7 days from when I had my HyperWallet approved before I got the money into my HyperWallet account. I recommend you set up auto withdraw. You can send money to PayPal, Venmo or bank account.

EV Battery overview
Batteries are the key differentiator between the various EV manufacturers. The amount of energy stored in the battery determines the range of the EV, thought to be a major limitation on EV sales.


Consumers tend to worry that an EV with a range of 80 to 250 miles on a single charge would be inconvenient for long trips due to the time it takes to recharge the battery. Commercial batteries need to ensure there is quick recharge and less time between charges


The lithium-ion battery is important because it makes EVs expensive than ICEs. Battery costs per kilowatt-hour (kWh) declined from roughly $1,000 per kWh in 2010 to $227 in 2016


Lithium-ion batteries made up 70 percent of the rechargeable battery market in 2016
BNEF projects that global production capacity for lithium-ion batteries will increase from 103 gigawatt-hours (GWh) in the first quarter of 2017 to 273 GWh by 2021.


The battery manufacturing supply chain has three main parts:

cell manufacturing,

module manufacturing, and

pack assembly.

Why was @LudwigAhgren's Twitch stream yesterday a masterpiece in creating live content?

Ludwig started off with a high energy intro with background music that sounded like an entrance theme to a WWE wrestler (or a Saturday morning TV show).

He then moved onto a segment where he attempted to break a 'world record' for speedrunning Unban Bingo.

(a trending piece of content right now, with in-jokes with the Twitch community and funny content that can be repurposed for YouTube).


Ludwig follows this up with a 20 slide presentation on 'how to make it big as a streamer'.

He engaged viewers into chat by asking them to vote directly in chat temporarily, which perfectly broke up what could have been a 'boring' presentation (spoiler, it wasn't boring).


He follows this with a Q&A and answers as many questions as he could, again, engaging chat.

THEN.... we get a PogChamp emote tier list of every PogChamp so far.

THREAD: 15 of the most useful razors and rules I've found.

Rules of thumb that simplify decisions.

Bezos' Razors:

• If unsure what action to take, let your 80-year-old self make it.

• If unsure who to work with, pick the person that has the best chances of breaking you out of a 3rd world prison.

Skinner's Law:

• If procrastinating on an item, you only have 2 options:

1. Make the pain of not doing it greater than the pain of doing it.

2. Make the pleasure of doing it greater than the pleasure of not doing it.

Luck Razor:

• If stuck with 2 equal options, pick the one that feels like it will produce the most luck later down the line.

I used this razor to go for drinks with a stranger rather than watch Netflix.

In hindsight, it was the highest ROI decision I've ever made.

Bragging Razor:

• If someone brags about their success or happiness, assume it’s half what they claim.

• If someone downplays their success or happiness, assume it’s double what they claim.

The map is not the terrain.

SRI KALAHASTI KSHETRAM, CHITTOOR (AP)
#bharatmandir

Panchbhootasthalam representing vayu element, also called Dakshin Kailasha.
As per Shiva’s boon, Vayu is incarnated here as Shiva and worshipped as Kalahasteeswara.
The kshetram is also associated with Rahu and Ketu.


The Kshetram is named after 3 devotees of Shiva- a snake, spider and elephant who worshipped a lingam in the forest. Elephant did jal abhishek with water from its trunk, spider protected it from dust by weaving a web on it and snake adorned it with his jewel.
@GunduHuDuGa


Once, the web and jewel got washed away when elephant sprayed water on the lingam. Angered snake entered elephant’s trunk and bit him but died in the process. The agitated elephant trampled the spider accidentally. Shiva gave moksha to all three.


Hence the name-Sri for Spider, kaal for snake n hasti for elephant.

Shiv bhakt Kanappa is said to have plucked his own eye to put it on the lingam here when he saw blood oozing from the eye on the lingam
This place is the ultimate location for Rahu Kethu Sarpa Dosha Nivarana.
