maybe it's just leftover urges from being a toddler putting round pegs in square holes but every time I see a video card like this on ebay I want to buy it and also some RAM chips to fill it with

 when I win the lottery I'm gonna buy all of these and a bunch of RAM chips, put them together, and then relist them right back onto ebay
I have a dream that one day all the super VGA cards on ebay will have full ram expansion sockets
that's a nice VLB video card you have there
be a real shame if someone were to UPGRADE ITS RAM
huh, I don't think I've ever seen RAM in that package
QFP DRAMs?
this one doesn't even have sockets.
you have to solder more RAM onto it
A CHALLENGE!
this one has ram slots on a daughtercard!
I think because it's a dual-output card... I think they made it dual-output by basically putting two cards on one card
remember when matrox made those AGP cards which had a laptop RAM slot on them so you could just use standard RAM in them?
beautiful
all slots filled
my skin is clear
the future is bright
all rams socketed
all rams filled
warm up the soldering iron, we got another one missing sockets
if you fill the ram sockets on your VGA cards, you may not be thanked much in this life, but you will be rewarded when you go to meet your maker.
as jesus said, in the red text, blessed are those who add more RAM to their supervga cards
apparently ATI also did that laptop-ram thing, according to this picture from an ebay seller who doesn't understand white balance
this EISA card has no obvious RAM sockets, but there are some suspicious pin headers near the ram chips.
so I bet you can upgrade this, you just need some stupid proprietary daughterboard
this guy managed to take 3 pictures of the same card, none of which are remotely in focus
matrox did that same daughterboard RAM thing, as you can see here, in some kinda blurry photos:
maybe I should take this into account when I build my MDA clone
design it for upgrading to more RAM
yeah, the MDA only has 4K of ram and can only use 4K of ram, but what if... it had more?
sure it only has a 80x25 character text screen, but if you had more RAM you could have more pages!
it reserves 32k of address space anyway, so you could have 8 pages of text screens
why not add a DDR3 slot?
"yeah, this is my upgraded Foonetronics Monochrome Display Adapter. I put in that 16gb DDR3 stick, and now I've got FOUR MILLION PAGES of text available!"
small brain: single buffering
big brain: double buffering
cosmic brain: triple buffering
multiversal infinite brain: four milluple buffering
I have no idea if that's remotely close to the english tuple name for a million and I don't really care. I don't think anyone has seriously tried to figure it out

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.

foolish people like to quote that "science says there are only two genders". This is incorrect.

Science instead says that in addition to the regular genders, there are 25 Science Genders, shown here. (tag yourself I'm Skull)

So there's a class of puzzles called "river crossing puzzles" which involve having to cross a river on a boat/bridge containing some set of individuals/items with restrictions on which ones can be on the boat/left on each shore, right?

and the most common subclass of these problems is the one where you have 3 items/animals to cross with.
This is alternatively called the "fox, goose, and bag of beans" or "wolf, goat, and cabbage" puzzle.

the idea is that your boat can only carry one item at a time, but if you leave the wolf/fox unattended with the goat/goose, the wolf/fox will eat the goat/goose.
and similarly, the goose/goat will eat the beans/cabbage if left alone

so you have to set up a set of actions that never leaves either side of the river in one of the lose-states.

the solution to this variant being:
1. take the goat/goose over
2. return empty
3. take the wolf/fox over
4. return with the goat/goose
5. take the cabbage/beans over
6. return empty
7. take the goat/goose over

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.

A fun fact on the wikipedia page for the metal–oxide–semiconductor field-effect transistor:
it is the most frequently manufactured device in history, and the total number manufactured from 1960-2018 is 13 sextillion.

That's 13,000,000,000,000,000,000,000.


Though this picture is a bit misleading.

Even with devices this small, we couldn't make 13 sextillion of them in 60 years.

So imagine a chip like this. It's the 555 timer, which is one of the most popular integrated circuits ever made.

In 2017, it was estimated a billion are made every year.


And at the heart of it is the die, which looks like this:
(from Ken Shirriff's blog)
https://t.co/mz5PQDjYqF


And that's fundamentally a bunch of CMOS transistors (along with some diodes and resistors), which are a type of MOSFET. How many of them are on a 555?

about 25. Not many, but it's a very simple chip.

The 2018 State of JavaScript survey is out. They got 20,000 responses and have some delicious, delicious data. I'mma thread in some highlights:

First up: JavaScript flavors. There's TypeScript at 47% adoption, a tad higher than npm's own survey results (which said 46%). npm's survey is coming up again soon and will ask about TypeScript in a lot more detail.


I really, *really* like SoJ's "would not use again" question, which lets people who've abandoned a tech self-identify. This is noticeable in the graph above with Flow users -- 41% of people who've used Flow say they wouldn't use it again.

Now JavaScript frameworks. It's been a full year since npm's survey, so these numbers differ from ours in the directions I expected:
React 65% (vs. 60%)
Vue 29% (vs. 24%)
Ember 5% (vs 4%, I was expecting a bigger rise)

But there's a shocker in here: Angular.


npm's survey had Angular at 40% last year and SoJ has it at either:
- 58% (if you include those who don't want to use it again)
- 24% (if you count only those who like it)
Since npm's question didn't ask if they intend to *continue* using it I think that might explain this.

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 it turns out that Google Chrome was making everything on my computer slow *even when it wasn’t running*, because it installs something called Keystone which is basically malware.

I made a website because this shouldn’t

Wired first reported on how bad Keystone was 11 years ago when they put it into Google Earth (they seem to put it in all their popular

The fact that Keystone hides itself in Activity Monitor is bizarre. (The only sign of it was excessive CPU usage of WindowServer which is a system process).

I don’t know if Google was doing something nefarious with Keystone, or a third party figured out how to (which Wired warned about). But either way, I’m not inclined to give Google-the-organization the benefit of the doubt (despite the many good people who work on Chrome)...

...since it's been a decade+ and this still hasn't been "fixed".

There is no reason for auto-update software to need to do what Chrome/Keystone was doing. It also has a long history of crashing Macs.

People sometimes ask me what my vision of DeFi is. This is a very tough question. DeFi is very messy with thousands of experiments happening. But high level, I think DeFi will go through 2 phases:

During the 1st phase (next 2-5 years), we'll continue to build games, casinos, and speculative products.

This sounds uninspiring. But it has two main important consequences.

1) This will ultimately lead to hundreds of millions of users to install wallets and get uncomfortable with the UX.

2) This will force the tech (especially scaling) to mature.

Once we've achieved these two goals, phase 2 begins. In phase 2, products that serve real economic activities / integrated with the real economy will be built and flourish.

Right now, such products barely exist. @terra_money comes to mind. But this is the kind of products that I really look forward to. They are more economically sustainable, and create more value.

I read two-and-a-half decades worth of Jeff Bezos’s Amazon shareholder letters.

It’s like a mini MBA.

Here I’ve pulled out a free guide for startups, investing, marketing, and “web3”🧵

(It’s a thread, not an ebook)


First, why the focus on web3?

It’s the mid 90’s. A 30-year-old Jeff Bezos is trying to raise money for Amazon. And investors are wondering,

“What’s this internet thing?”

Fast forward, the year is 2022, and folks today are wondering,

“What’s web3?”

Now, a little background…

In 1994, Bezos quit a well paying job to start Amazon.

It wasn’t an easy decision. But Bezos used his famous “regret minimization framework.”

In other words, he didn’t want to be 80 and regret not doing what he really wanted to do.

But what did he want?

Bezos didn’t set out to disrupt retail from the outset.

He simply wanted to come up with a business idea based on the internet and then let the internet grow around it while he kept working on it.

Today, that idea is worth $1.7 trillion and counting.

Moving on to the lessons…

Each year since 1997, Bezos has written an annual letter to Amazon shareholders.

These letters reveal a great deal of lessons and secrets behind his massive success.

So what are they?

AHOBILAM NARASIMHA SWAMY KSHETRAM: KURNOOL (AP)
#andhratemples

Ahobilam is the place where Prabhu appears in his fierce form, called Ugra Narasimha, who is Svayambhu (self-manifest).
Ahobilam is one of the 108 Divya Desams. It has 9 shrines for different forms of Narsimha.


Ahobilam was the exact place where Sri Narasimha appeared and tore apart Hiranyakashipu to save Prahlad. At that moment, all the Devas appeared and praised him as Ahobala (Aho is mighty and bala is strength). So the place came to be called Ahobilam.


Out of the 9 shrines, most famous is the Ahobila Narasimha Swamy where Prabhu is seen as Ugra Narasimha.
In another shrine, Prabhu appears as Malola Narasimha Swamy. Malola means beloved of Lakshmi. Here Prabhu is in peaceful mudra with his consort Ma ChenchuLakshmi.


Jwala Narasimha Swamy shrine is the actual spot where the fierce anger of Prabhu reached its culmination when he tore Hiranyakasipu.

Ugra Stambham is the pillar from which Narasimha appeared with such force that the entire hill split into two.

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

https://t.co/7QIx5CFdfJ


The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

Neurologist, Psychologist.
These natives are Selfless and Sacrifice self for others. They gets Fame and Success but they just don’t care.

2. Ketu in Bharani Nakshatra:

They are good at Flirting, Attracting opposite sex, studing ancient subjects. They are also Great at Creativity and Artistic activities. The are lazy but they are really open minded who handles situations really well.

In Past life they have handles many things which is now helping them to make things easier in this life. They are great Leaders too.
