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.

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?

So I got out some CF cards and noticed something odd about this one. Do you see the weirdness?


How the fuck is a CF card "USB Enabled"?


So CF cards are a weird beast that act as either a PCMCIA card or an ATA/IDE card depending on a mode pin.

They're definitely not USB.

And it's not like that weird SanDisk card I have which you can fold in half and plug it in as a USB device.


It turns out the reason for "USB Enabled" is because it's a Lexar drive from the jumpSHOT era.
This is a normal CF card in most cases, you can use it in normal CF card readers and such

yesterday: somewhat viral post about shooting billionaires into the sun (and my stupid "WELL ACTUALLY" reply)
also yesterday: elon musk leaves twitter "for a while" and jeff bezos steps down

COINCIDENCE? I THINK NOT!

elon's gotta be off twitter for a while because they don't have wifi on the SunCrasher 9000, and bezos keeps stealing his phone anyway

elon thought he wouldn't need it because of starlink but THE SATELLITES ARE IN LOW EARTH ORBIT, MUSK, AND YOU'RE HEADED TOWARDS THE SUN

bill gates is the only one who still has internet access because he remembered to set up a long enough ethernet cable

(although tim cook joked that was just because his WinPhone doesn't have wifi support anyway)

zuckerberg asked if bill gates would let him use the network connection for a while and while billy g was fine with it, it turns out none of the other billionaires brought phones with built in ethernet ports

finally, the win95 phone comes up top!

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.

Two years ago on a weekend, I built a tool to make it easier to evaluate Twitter accounts. Since then 36590 people used it to analyze 55390 different Twitter accounts.

Over the last months @mmkaradeniz and I made a new version. We launched it last night:

@accountanalysis doesn't use machine learning or AI „magic“. Instead of telling users if an account is authentic or not, it helps them to evaluate the accounts themselves.

It visualizes the different features (date, time, type, app, etc.) of Tweets to make them interpretable. /1

@accountanalysis The core concept is still the same, but it looks much better and is easier to operate. Not only for the users, but us developers as well. Enabling us to continuously roll out new features in the future.

Side-by-side screenshots of the old and new version. /2


@accountanalysis Some people had questions what different charts displayed and how they could be interpreted. There are now explanations for all charts, that can be toggled on and off at any time. /3


@accountanalysis The selected/retrieved Tweet count moved to the top to make it clear that not all Tweets of an account are analyzed. 3200 is the API limit by Twitter. It's possible to get more through the Premium API, but I don't think people would pay $100+ for the analysis of one account. /4

Observing the public conversation around FB, and the private ones happening among techies and ex-FBers, I think the mutual misunderstanding is worse than when I set out two years (and 500 pages) ago to (in a small way) bridge that gulf.

We're basically fucked.

The tech world has gotten so huge, self-reinforcing, and insulated from reality they can no longer even vaguely look at themselves (and their actions) as others do. They just live on a different planet than most people.

Conversely, the average tech consumer doesn't understand the technology that has slowly taken over their lives, and their designated emissaries to figure it out--politicians, pundits, regulators, journalists--understand it barely better than they do, and have their own agendas.

To say more than generalities for a moment, here's what I think is likely the core problem.

Techies take weird, improbable visions, and make them realities: some BS pitch deck to a VC, mixed with money and people, really does turn into some novel thing.

Most people work inside a legacy industry that's evolved that way over time (usually for good reasons), and they think about the future via some analogy with their present (which is a function of a long-ago past). The interruption that tech will introduce is often hard to grasp.

So, today, for the first time in 25 (!) years of Apple, I downgraded. From the 2016 MacBook Pro to my 2013, which I had kept in a drawer...


It was pretty simple to do—Apple Time Machine backups let me do it with one click.

That first tweet captures, in two pictures, how badly Apple has “lost the plot” (to quote @wylieprof). On the right is the Apple MagSafe adapter, from 2013. On the left, what I had “upgraded” to.

Thanks, Apple! I really was nostalgic for worrying about yanking my computer off the table.

Oh and I really appreciated not knowing if my computer was charging. What was great was the little whoop sound you used, so that the speaker before me could be informed I was charging my laptop.

Just imagine there's a global pandemic forcing everyone to stay home and buy their stuff over the internet. And you've been working on your sanitization-on-demand startup. You've got more users than you can count! ... literally, because your data's all over.

Now you're a multi-national international country with privacy issues because your information is all over the place.

Now a user writes to request you delete their data. Where is it? How do you do that? Who's responsible for privacy in your business.

How do you operationalize privacy rights?

Primary stakeholders:
* Legal
* Business
* Engineering

We spend a lot of time on Twitter analyzing the legal rulings, but it's harder where the "rubber meets the code" 🥁

Please please please take your cyber security seriously even if you don’t consider yourself a high risk person. Here are a few easy things to start with. 1/n

Switch from WhatsApp to Signal and enable disappearing messages. Most of us cannot stop using WhatsApp entirely but at least turn off back ups to Google Drive or iCloud. 2/n

Do not have private conversations using the messaging service on any social media platform like Facebook, Instagram or Twitter. 3/n

Switch from Gmail to ProtonMail or any other secure email service provider. 4/n

If you're a college student who wants to pay off all your loans... here's an idea for you:

It takes ~$5k to start and will make ~$30k a year of profit

It won't get you rich, it'll pay for college.

(..and will teach them more about business than they’ll learn in school)

The idea isn’t sexy. But it works:

**Plastic Moving Bin Rentals**

Everyone knows moving sucks. The worst part is being stuck with 400 cardboard boxes at the end of your move.

Instead - @benmlevy told me about Gorilla Bins. They dropoff plastic moving bins, & pickem up later.


Let’s break it down. Our goal is to pay for college (~$30k profit per year).

To do that, I think we’ll need $50k in revenue.

The avg move (a 2 bedroom apartment) is $180

To hit our goal, we need do ~5.5 moves per week

COSTS?

How many bins do we need to buy up front?

5.5 moves a week x 50 bins = you need 275 bins. Let’s round up to 300 to be safe.

Ok let’s hop over to @uline to see how much these bins cost

Bingo. Bins cost about $15 a piece.

$15 x 300 bins = $4,500 initial startup costs.

Time to beg your parents or a rich aunt to lend you money to get the biz rolling (...or just take $5k of student loan money and invest it here…)

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.

Sri Sanjeevi Rayar Temple located in Ayyangar Kulam,near Kanchipuram,TN

#Thread

Ancient but beautiful temple dedicated to Hanuman. This temple is a legendary one. According to the Sthala Puranam of Sanjeevi Rayar temple,it is associated with an episode from Ramayana.


Legend story -Hanuman was flying from Himalayas to Lanka bearing Sanjeevi hill to revive Lakshmana during battle between Rama& Ravana, a piece of the Sanjeevi Parvat fell at this place.Many believe this legendary story & even today that no one here dies of any kind of poisoning.

From historical background of the temple it is known that temple was originally built by a great scholar &administrator Kotikanyadanam Lakshmikumara Tatacharya. Temple itself&village were named following name of great scholar Tatacharya, who was then popularly known as Ayyangar.

He was the royal preceptor of Vijayanagara emperor Venkata Raya who had his capital at Chandragiri in AP.Upon returning from a pilgrimage,robbers tried to attack Tatacharya at this place. Being a great devotee of Hanuman,he instantly composed a poem in Sanskrit praising Hanuman.


The bandits immediately ran away &Tatacharya decided to build a temple dedicated to Anjaneya at that very place.This Sanskrit poem is called Hanumad Vimshati, has been inscribed in Grantha script inside this temple.The huge temple tank called Tatasamudram, in honor of Tatacharya.
