does bubble memory count as solid state?
I guess? I mean, it has no moving parts. but it requires preheating and involves movement of magnetic fields across a surface...

 it's kinda like a traditional hard drive where you don't spin the disc, you just trick all the bits to migrate off the edge
who called it "bubble memory" and not "lemming bits"
(obligatory "lemmings don't throw themselves off cliffs, that's an urban legend")
(obligatory "the idea that disney invented that urban legend it itself an urban legend, they just helped popularize it")
@quartizine has the good point that it's not just about movement. Vacuum tubes aren't solid state!
https://t.co/VG3XdoQ6OZ
in any case, that still probably means bubble memory is solid state.
It has to warm up, yes, but it doesn't melt. The crystal remains solid, and only the magnetic fields move.
interesting this sort of solid-vs-gaseous/liquid distinction means that for optical discs (which aren't normally solid state, because they spin) could conceivably be made solid state... EXCEPT for CD-R/CD-RWs when you're burning them.
because CD-Rs involve a (very brief) one-way state transition from solid->gas->solid, and similarly CD-RWs are solid->liquid->solid every time you write them.
and by "could be made solid state", there's no actual reason WHY a CD-ROM has to spin. It just means you don't need as complicated a laser arrangement
because if you think about how an optical disc works, it's really a 2D surface: you've got the in/out axis (towards the spindle hole or towards the edge) and the around-the-disc axis
and the laser head in your CD-ROM drive has a stepper motor or voice coil that's used to move the laser on the in/out axis.
The other axis is managed by spinning the disc, and waiting for it to rotate around.
but you could totally build a CD-ROM drive that works more like a plotter or 3D printer: you could move the head in two dimensions, and not have to spin the disc.
why would you do this?

there's really not any reason.
although the Lasercard format works this way.
https://t.co/JlCPyOXXzL
I've not opened up my lasercard drive (I was kinda hoping to find some media for it...) but I think it doesn't fully move the head. it's mostly a moving-mirror system.
although that brings up another point worth arguing about for a medium:
does it count as solid state if doesn't move while in use, but it's connected to things that do?
although if you want to get relativity-absurdist with that, you could then argue that, because there are no special reference frames, that technically traditional hard drives don't spin.
they're immobile, and the universe spins around them?
although now t hat I'm thinking about it I'm not sure rotating reference frames count as "normal", because you can feel forces from the rotation that wouldn't be the same if it was the rest of the universe spinning around you
it's too 6am for this physics bullshit
ANYWAY I think the point out vacuum tubes made me realize something:

solid state discs aren't "solid state" because they're not moving. not moving has nothing to do with if they're solid state or not
solid state disks are solid state because they use solid state electronics, and traditional spinning-rust media does not.
"solid state electronics", as a term, was coined to distinguish semiconductor electronics from vacuum tube electronics.
vacuum tubes use a (near) vacuum and a gas of particles/electrons/ions moving within it.
whereas solid state electronics use a semiconductor, which is a solid crystal. It's just currents being controlled by currents within the solid piece of silicon or germanium or whatever.
so "solid state" refers to things like transistors and diodes and integrated circuits.
and what are SSDs made out of?
integrated circuits. all the flash memory stuff happens inside a die of silicon.
whereas traditional discs are a bit circle of rust spinning around with magnetic fields on it, with a little electromagnet on an arm that moves around it to read off or write magnetic domains
which is a lot of things, but it's not transistors, diodes, or integrated circuits. So it's not "solid state" in the same way an orange isn't solid state: it's not made of remotely the same things.
so I think the answer to "is bubble memory solid state?" is both "yes" and "no".
it's "yes" in the sense of: the state of the memory storage medium is solid, and is always solid. at no point is it liquid or gas.
it's "no" in the sense of: when we say "solid state", we mean "solid state electronics", which it isn't.
It's a chunk of garnet, not anything semiconductory
btw, this also means that core memory isn't solid state either, since it's similarly electromagnety, even though nothing is moving.
so I'd argue that you could say it's something like "solid phase memory" but "solid state" has a pre-determined meaning in electronics and applying it to things that aren't made of "solid state electronics" is confusing and incorrect.
ANYWAY this reminds me of something I was talking to @gewt about the other day:
I want to make a rotating solid state disk.
the obvious way to do this is slip rings. I did a whole thread on these:
https://t.co/aVU1sri57P
but I think SATA might be too fragile and complicated to easily put through a slip ring, so I think I'm gonna go for USB.
basically take an SSD, a SATA2USB adapter, and then get a USB slip ring (I think Moog (not that one) sells off-the-shelf ones!) and a motor.
you see?

So Sony has this format called Optical Disc Archive, right? It's a high-density storage cartridge, but it turns out it works by cheating.


because if you open it up (which you should never do. trust me on this one)
it turns out... it's blu-ray.


it's a big STACK of blu-ray


And the idea is that Sony built some very complicated drive which you can slot this cartridge into, and it'll open it up and grab out the right disc and just read/write that one

then when you hit the eject button, it shoves the discs back in and closes up the case, and hands you the cartridge.

ending #2 is some very thin credits


ending #3 is reportedly the "true ending", at least on the European release. The Japanese version has 35 endings.

This one is... more serious? a little?

So I was in the shower this morning, and started wondering:
Do you think the people implicated in Jeffrey Epstein's book had a general "Dead men tell no tales" slush fund?
Or did they have to separately organize his assignation?

I'm just imagining that on August 10th there's a big traffic jam of hired killers all running into each other like


some guy's sneaking out of a vent when a guard walks in, sees him, and goes "HALT!" and the vent guy goes "SHIT!", then notices the guard's ill-fitting suit. "Wait, ...Steve? Is that you?"

"Alex! I haven't seen you since the Reno heist! What are you doing here?"
"Same thing as you, looks like."

"I'll be damned. Well, I've already knocked out the guard, you want to let me finish this?"
"Yeah, go ahead. I'll get paid either way."

1. in the beginning, browsers didn't have download statusbars
2. firefox got a browser statusbar extension. it was configurable and worked well
3. chrome cloned it without options and it didn't work as well

4. firefox realized chrome was faster and more secure at everything and therefore dropped extensions
5. now firefox doesn't have a download statusbar either

6. someone reimplements download statusbars in firefox's new web-extensions format. it's terrible because of the inherent limitations of the significantly less flexible and powerful extension format

7. CHROME WINS! (with its terrible download statusbar implementation which can't be fixed by users, because No Options and No Skins and No Extensions)

this is where we are now

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."

The entire discussion around Facebook’s disclosures of what happened in 2016 is very frustrating. No exec stopped any investigations, but there were a lot of heated discussions about what to publish and when.


In the spring and summer of 2016, as reported by the Times, activity we traced to GRU was reported to the FBI. This was the standard model of interaction companies used for nation-state attacks against likely US targeted.

In the Spring of 2017, after a deep dive into the Fake News phenomena, the security team wanted to publish an update that covered what we had learned. At this point, we didn’t have any advertising content or the big IRA cluster, but we did know about the GRU model.

This report when through dozens of edits as different equities were represented. I did not have any meetings with Sheryl on the paper, but I can’t speak to whether she was in the loop with my higher-ups.

In the end, the difficult question of attribution was settled by us pointing to the DNI report instead of saying Russia or GRU directly. In my pre-briefs with members of Congress, I made it clear that we believed this action was GRU.

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.

@zkat__ I'm in the position that I actually find npm / yarn the best ecosystem. Whenever I use something else I always end up stubbing my toe into something thats missing / feels wrong.

Ex. Cargo seems to neither have a concept of devDependencies nor peerDependencies.

I also can't understand why it wouldn't have an "add" command to add a new dependency. And I'm no fan of Toml, json is greate (easy to parse and build tooling around), and the better option in my opinion would be json5.

C / C++ seems to just not have language package managers. The linux / bsd crowd seem to have decided that the system package manager also should be the language package manager. Which might have been fine if every Linux distro used the same system package manager.

Instead we end up with a N x M problem. Where we have a bunch of different operating systems and they all support multiple system package managers. So there's no easy way of distributing, referencing and updating C / C++ packages.

It is also my opinion that the compiler / runtime should be a package dependency. I don't like Rust's split between rustup and cargo (they should have been one tool). Similarly it would be better if you added Node as a dependency to package.json, that way we wouldn't need NVM.

(THREAD) Pre-election Russia collusion may take down Trump. It's equally possible the Trumps' pre- and post-election collusion with Saudi Arabia, the UAE, and Israel will do it—a course of collusion also connected to the Kremlin. I explain here. I hope you'll read on and retweet.


1/ I must stress how unbelievably complex the "Grand Bargain" theory of the Trump-Russia case is—a different thing from saying it's not substantiated. It's substantiated in *almost every single particular*—it just *also* happens to be very confusing. Not byzantine—just confusing.

2/ The basics: Saudi Arabia, Israel, and the UAE all view Iran as their chief regional enemy. Iran is propped up by Russia. Therefore the Saudis, Israelis, and Emiratis all need a US government willing to find a way to get the Kremlin to *stop* supporting Iran in the Middle East.

3/ The best way to get Russia to stop supporting Iran—or reduce support—was/is to drop all sanctions on Russia over its 2014 annexation of Crimea, as that'd be worth *trillions* to the Kremlin over the next decade. Everyone knew that Clinton wouldn't do this—and that Trump would.

4/ Per the NYT, on August 3, 2016, Donald Trump Jr. met secretly at Trump Tower with a Saudi and Emirati emissary, George Nader, as well as an Israeli intelligence expert, Joel Zamel, with *significant* ties to both Israeli intelligence *and* Russian oligarchs allied with Putin.

The Ife Primary Education Research Project (1970-1983).

aka

The Ife 6-Year Primary Project.


In 1970, as the Director of the Institute of Education of the then University of Ife (now Obafemi Awolowo University, Ile-Ife), later Dean Faculty of Education, Prof. Babs Fafunwa & his team embarked on one of the most groundbreaking research projects in education for Yorubaland.


The aim of the project was to test the hypothesis that the best instructional medium for good concept formation at a very tender age is the mother tongue.

This was bolstered by the observation that “of all the continents and peoples of the world, it is only in Africa…

…that formal education is offered in a language that is foreign to the child.”

So, Yoruba was to be used & tested as an exclusive medium of passing information or instructions to a set of pupils.

The project was based on the premise that:

(a). the child will benefit culturally, socially, linguistically & cognitively.

(b). the child’s command of English will be improved if he is taught English as an entirely separate subject by a specialist teacher through the 6 years.

🌺कैसे बने गरुड़ भगवान विष्णु के वाहन और क्यों दो भागों में फटी होती है नागों की जिह्वा🌺

महर्षि कश्यप की तेरह पत्नियां थीं।लेकिन विनता व कद्रु नामक अपनी दो पत्नियों से उन्हे विशेष लगाव था।एक दिन महर्षि आनन्दभाव में बैठे थे कि तभी वे दोनों उनके समीप आकर उनके पैर दबाने लगी।


प्रसन्न होकर महर्षि कश्यप बोले,"मुझे तुम दोनों से विशेष लगाव है, इसलिए यदि तुम्हारी कोई विशेष इच्छा हो तो मुझे बताओ। मैं उसे अवश्य पूरा करूंगा ।"

कद्रू बोली,"स्वामी! मेरी इच्छा है कि मैं हज़ार पुत्रों की मां बनूंगी।"
विनता बोली,"स्वामी! मुझे केवल एक पुत्र की मां बनना है जो इतना बलवान हो की कद्रू के हज़ार पुत्रों पर भारी पड़े।"
महर्षि बोले,"शीघ्र ही मैं यज्ञ करूंगा और यज्ञ के उपरांत तुम दोनो की इच्छाएं अवश्य पूर्ण होंगी"।


महर्षि ने यज्ञ किया,विनता व कद्रू को आशीर्वाद देकर तपस्या करने चले गए। कुछ काल पश्चात कद्रू ने हज़ार अंडों से काले सर्पों को जन्म दिया व विनता ने एक अंडे से तेजस्वी बालक को जन्म दिया जिसका नाम गरूड़ रखा।जैसे जैसे समय बीता गरुड़ बलवान होता गया और कद्रू के पुत्रों पर भारी पड़ने लगा


परिणामस्वरूप दिन प्रतिदिन कद्रू व विनता के सम्बंधों में कटुता बढ़ती गयी।एकदिन जब दोनो भ्रमण कर रहीं थी तब कद्रू ने दूर खड़े सफेद घोड़े को देख कर कहा,"बता सकती हो विनता!दूर खड़ा वो घोड़ा किस रंग का है?"
विनता बोली,"सफेद रंग का"।
तो कद्रू बोली,"शर्त लगाती हो? इसकी पूँछ तो काली है"।
