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.

I like how mediawiki exports pages because there's nothing I enjoy more than parsing a 1 gigabyte XML file

and I'm doing simple-english-wiki! it's way smaller than english wikipedia
I can only imagine how impossibly unparsable that nightmare is

fun fact: when programmers need to write code to extract data from an XML file, the process usually goes like this:
1. find XML file
2. open it in a text editor, see what the structure is
3. write some code that parses that

do you really want to open a 1 gigabyte XML file in your text editor?

do you want to fucking die?

I used to run into this problem back when I worked for the government, because sometimes I'd click a database query log (don't ask why our logs were in XML, it's... complicated) and it would turn out to be 100mb

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.

I think chrome is intentionally providing shitty user experience for the blocking of HTTP downloads on HTTPS pages, in order to push developers to fix it faster.

you click a HTTP download link on an HTTPS page and what happens? NOTHING. No error page, no pop-up saying "BLOCKED BECAUSE SECURITY", the browser is just like "did you click? I didn't notice"

it just sticks an error in the JS console.

which I'm sure everyone notices


BTW, this is probably going to get fixed soon, but as of Version 87.0.4280.141 (which seems to be latest) there's a bug which lets you bypass the block, most of the time.

Incognito mode.

Basically chrome won't let you download it because it has the context of you clicking it from a HTTPS page.
But it loses the context if you use the "open link in incognito window" option.

brew / bru : / to make (beer, coffee etc.) / verb: begin to develop 🌱

A place for you to enjoy premium content while supporting your favorite creators. Sort of like a ‘Consumer-facing Patreon’ cc @jackconte

(we’re still working on the pitch)

3/ So, why be so transparent? Two words: launch strategy.

jk 😅 a) I loooove doing something consistently for a long period of time b) limited downside and infinite upside (feedback, accountability, reach).
cc @altimor, @pmarca


4/ https://t.co/GOQJ7LjQ2t domain 🍻

It started with a cold email. Guess what? He was using BuyMeACoffee on his blog, and was excited to hear about what we're building next. Within 2w, we signed the deal at @Escrowcom's SF office. You’re a pleasure to work with @MichaelCyger!

5/ @ycombinator's invite for the in-person interview arrived that evening. Quite a day!

Thanks @patio11 for the thoughtful feedback on our YC application, and @gabhubert for your directions on positioning the product — set the tone for our pitch!

X : Our executive team is concerned that we need to up our game in order to out innovate Amazon.
Me : Do you map?
X : Yes
Me : Like this?
X : No. What's that?
Me : A map of a tea shop.


X : Why is that a map?
Me : Long story, all to do with how space has meaning. To keep it short, maps help people to focus on user needs, the components involved, to communicate missing components and scenario play ideas like staff becoming robots.


Me : They’re also good for measuring and managing capital flow, making investment decisions, removing bias and getting rid of duplication.
X : I don’t see how that helps with innovation?


Me : Well, innovation is a tricky word because we use it to describe many things. If you’re talking about differentiation with the adjacent unexplored then you’re experimenting in the “uncharted” space e.g. immortality with magic provided by the special custom built kettle.


X : That sounds like nonsense.
Me : A lot of what people think will be the next great innovation is nonsense. Actually, most of it is. That’s the nature of the uncharted space, it’s experimental, high risk and generally results in failure.
X : We need more reliable innovation.

I could create an entire twitter feed of things Facebook has tried to cover up since 2015. Where do you want to start, Mark and Sheryl? https://t.co/1trgupQEH9


Ok, here. Just one of the 236 mentions of Facebook in the under read but incredibly important interim report from Parliament. ht @CommonsCMS https://t.co/gfhHCrOLeU


Let’s do another, this one to Senate Intel. Question: “Were you or CEO Mark Zuckerberg aware of the hiring of Joseph Chancellor?"
Answer "Facebook has over 30,000 employees. Senior management does not participate in day-today hiring decisions."


Or to @CommonsCMS: Question: "When did Mark Zuckerberg know about Cambridge Analytica?"
Answer: "He did not become aware of allegations CA may not have deleted data about FB users obtained through Dr. Kogan's app until March of 2018, when
these issues were raised in the media."


If you prefer visuals, watch this short clip after @IanCLucas rightly expresses concern about a Facebook exec failing to disclose info.

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.

Again sharing bank nifty intraday weekly straddle. How to play by selling straddle.
Mostly will work on Monday to Wednesday. Sometimes on Friday.
Why to pay your money to learn this if u can get it here.
U need only practice.
Let’s go.

Say bank nifty future is at 32000.
Sell both 32000 call and put.
Considering current volatile market lest say premium on Monday morning is 350 on both sides.
Sold with 700 points combine premium.
If bank nifty will trade in narrow range say +\- 100 hold it.
If moving 200 points

then exit previous sold straddle. Sell new one. Let’s say BN moved +200
Now sell 32200. If bank nifty will move here within range then u will get profit through theta decay. Follow same procedure for next 150-200 pts move.

This is only for single straddle sell position.

Now in second case sell three straddle. 31900/32000/32100
In case of 100 points move no need to change.
If 200 + then future is 32200.
Exit 31900 and sell 31200 straddle.
If moving another 100 then exit 32000 and sell 32300. Continue same with 100 points move.
If no move then

it will consolidate between 32000-32200 or 32100 to 32300 and u will get theta decay.

This is for normal move. Sudden big move may come anytime. So keep SL in system.
If u r selling at 350-350 then keep SL in system 475 for both legs.
Practice it. No need to attend webinar.

Oleg Karpov pisze, że gdyby Siergiej Sirotkin zdobył w pierwszej części sezonu więcej punktów od Strolla, to jego kontrakt z automatu zostałby przedłużony na kolejny sezon. Tak się nie stało i Williams ma możliwość szukania innych opcji i to właśnie robi. #F1pl

Czego w artykule brakuje, to informacji, że SMP prawdopodobnie przekazało Williamsowi część środków na sfinansowanie sezonu 2019. W przypadku zakończenia współpracy ekipa z Grove będzie musiała zwrócić te środki. #F1pl

To tłumaczy wysokie kwoty jakich Williams ma oczekiwać za fotel od nowego kierowcy. Jest pewnie próg opłacalności i dopóki nie zostanie osiągnięty, to zmiana z finansowego punktu widzenia nie będzie się zwyczajnie opłacała. #F1pl

Tyle można znaleźć w oświadczeniach prasowych... 😂😂😂

I'm gonna do my other star wars thread tomorrow, which will primarily be me yelling at a @RowanKaiser-shaped strawman for calling the First Order and The Resistance "cosplayers who the rest of the galaxy has to deal with"

the deal w/the New Republic, the First Order, and the Resistance is very weird and complex and I actually take issue with how Story Group frames the actual conflict.

pre-TFA stuff is presented as a "cold war" between the New Republic and the remnants of the Empire that form the First Order, which 100% makes sense.

But they frame the First Order's attack on the Hosnian system and the subsequent battle that takes place across TFA and TLJ as a full on war when it's very clearly a coup. A war implies at least equal standing, but the First Order completely wrecks shop and takes over the galaxy.

ok never mind I'm fucking doing this now.

The First Order fleet we see in TLJ is *not* the entire fleet of the First Order (I don't even think Starkiller Base was their main base of operations honestly, it couldn't have been considering they were operating out of Wild Space)
