It’s actually one of the most publicly documented aspects of the company, but never under the word ‘coefficient’ because the copy-writers (the linguists deciding how Facebook talks about itself on the site and in its blog posts, a surprisingly influential group) really hate the word. They manage to rephrase every interaction into a phrase, typically “how close you are with them”.

One recent example of a TechCrunch guide on News Feed [1] where “Creator” is actually coefficient or a more recent official version [2]. There was a very early “How does Facebook work?” company blog post that explained a surprisingly large amount of things. It was the only official resource for a long time. The explanations were clear, if read the euphemism “how well you know them” as (a rather obvious for data-engineers) “we batch-compute a rating on a dyadic graph at regular intervals (yes, that means weekly)”. Without that idea that all those phrases correspond to the same constant, that blog post and its successor are rather unhelpful.

Coefficient-ranking is indeed omnipresent internally, to the point employees regularly use the word in front of civilians without realising you are not meant to, almost daily. Explaining the concept and or even saying it’s called “coefficient” is fine: those blog posts are considered clearly explaining those by the PR team. You are simply advised to phrase things in a more humane way, like the blog posts do, because that helps people understand (it doesn’t: admitting a single constant number is imperfect helps a lot people understand the issues they have with the News Feed).

It’s mainly used both in front-end for suggesting interactions and as a data-engineering filter: the list of every friendship is a trillion long.

Awesome! A few times I've had to code together with my girlfriend and went for repl.it as a reflex, checked if it supported this feature or not because it seemed like it could! (Great (free??) product!) We would then use cloud9, but now it seems like that won't be necessary!!
> but it's hard to deny that it works. Australia has some of the lowest per capital road deaths in the OECD

Actually, we're in the middle according to the data, there's a few countries with better rates:

In regards to being fined for 5 km/h over the limit, there's no evidence that small increases in speed over the limit contributes to accidents. It's excessive speed that kills, like going 100 in a 60 zone. The other big killer is distraction and driver fatigue.

As for red lights, I'm fine with the strict rules there. I've almost been hit walking across the road by red light runners.

History will most likely remember these people as the completely incompetent board of director of the fossil fuel industry that presided over the final execution of the planet's habitable eco system. The fact that they were politicians or even the Prime Minister for 5 minutes briefly in late 2018 won't even be a footnote...
I wonder what definition of "volume" Susskind is using here? Something coordinate independent, presumably, though I don't really see how it's possible to get around the issue of GR allowing many equally valid slices of spacetime to be called "the present moment". Also, they can't be referring to the Schwarzschild metric here, since that's static, and the article states that the volume is increasing over time. It has to be some more complicated solution that describes the collapse of a star into a black hole. Maybe the Schwarzschild metric is the end state of such a collapse process and has infinite volume according to Susskind's definition, though that's just baseless speculation.
Wow. That’s far less than I imagined.
As a Detroiter I'm not surprised in the least bit. It seems yearly that some a'hole doctor is in the news for doing something terrible.

The practical limit for battery capacity is 100 Wh; beyond that you need airline approval to travel with it. Apple's 17" Unibody MBP had a 95 Wh battery, and when that was discontinued the 15" rMBP offered 95 or 99.5 Wh until the Touchbar was added. If Apple were to reintroduce a 17" model, it could only offer 19% higher battery capacity than the current 15", which means it probably couldn't offer any better battery life.

I'd rather just see the 15" rMBP get a bit thicker so that it can have more variety of I/O and stay at the ceiling for battery capacity.

> You can also think of a type as a set of valid values that a variable could hold

I would suggest avoiding this kind of thinking. Set theory and type theory are separate. Mixing them will only cause confusion and suffering.

> without changing the API

Pretty sure that loosening the return type constraints of a function or tightening the constrains of a variable that a function accepts would both change the API, is my understanding incorrect?

Citation? I am having trouble thinking of a major market where there's some company with 100% market share. Software has hudnreds of multi-billion dollar companies. Autos has hundreds? Until your scope gets very narrow, there's tons of competition.
This kind of ballooning makes me think there should be a rule for propositions (and maybe most funding in general) that when allocating funding for XYZ, there must be clear criteria upon which the funding is removed.

Like if the proposition had said "It'll probably cost $33B and take under three hours, and will be canceled if the estimated costs exceed $50B or the estimated duration exceeds 3 and a half hours."
But then they wouldn't be able to hand out favors and buy political clout with big construction firms and unions, which is sadly probably the main goal for the current project..

Sorry to be the license police, but I think that the attribution for embedding another project like that is a little unfair to the original authors, especially since this project is the more restrictive GPL 2.0.

https://softwareengineering.stackexchange.com/questions/2183...

"The fourth paragraph says that the copyright notice in the second paragraph must be reproduced. Users of the license [sic] substitute the [fullname] with their actual name. That is what constitutes "proper attribution" in the mind of the MIT: every user of the software can find out who wrote it if they want to."
In that case, you might want to read Damore’s memo. It’s not what you think.
Firefox has had its fair share of debacles this year too. Chrome works better on Linux for me, and Firefox is full of strange and unusual bugs which Mozilla shows little or no interest in fixing.

If Mozilla forked Chromium this year, Firefox would be a better browser (even with the very interesting developments coming from the Servo camp, E10S, etc. etc. etc.). Firefox has accumulated bugs, particularly around their implementation of SVG, since about 4.x, and it doesn't seem to be getting any better on that front.
Really cool, Repl.it is the best online bite-sized programming platform I've ever used. The breadth of languages offered is surprising (Brainfuck and Scheme?!), and things I would have thought wouldn't be supported were supported.

I say this in spite of an excruciating experience I had a few weeks ago where I led a Python for absolute beginners day-long workshop. I had tried Repl.it before writing the course materials and was mind-blown at how everything just worked, including the filesystem, which I needed for downloading NLTK modules. I decided to design the materials around Repl.it, letting me spare the class the possibly excruciating and definitely not fun experience of downloading and configuring Python and an IDE. Unfortunately, on the day of the workshop, Repl.it just didn't work for half the class, and for most of the rest, it was really, really slow. Hopefully this was just a hiccup.
Yeh you can elect to contest any fine in court. I've done it twice here in Aust, and had the fine thrown out both times, including a big $750 driving unregistered fine.

It takes about 4 hours or more out of your day to attend court which is obviously not possible for everyone.

I suspect that the position of most in the "US hacker community," whatever that means, is that public information is public. Individuals may have issues with the government or large corporations harvesting data in a systematic way but I'm pretty sure most would be reluctant to restrict, for example, individuals taking photos in public places. In general, the US tilts more toward the rights of individuals to say/write/publish as they please than Europe probably does.

If anything, the "US hacker community" is probably more suspicious of the government restricting such rights than the population as a whole is.

> fantastic demonstration of why i exclusively use git from a command prompt

What's described in that github issue happened to me as well the first time I used git via Visual Studio. I normally don't do that, but something told me to make a zip of everything before using git in VS. So that saved me big time.

Why in the world are the deletions not pointed to the Recycle Bin??? That's what it's there for.

So the UK spooks have a wonderful euphemism for this. "Equipment interference":

https://www.theregister.co.uk/AMP/2018/12/06/uk_gchq_bulk_eq...

Which, of course, leads on to a somewhat less specifically targeted "Bulk equipment interference", because once we have the capability, it'll _surely_ not get misused, right? I'm eagerly awaiting the hilarious verbal gymnastics they'll come up with to make a Technical Assistance Notice compelled "Bulk equipment interference" capability some how not a "systemic weakness"... I'm sure that'll end up in linguistics textbooks and industry jokes for decades...
I wouldn't get too comfortable owning business based upone Li-ion batteries, especially in long run. Li-ion can replace traditional combustion engines in some niche applications but is far away from completely replacing it. To me batteries feels like an intermediate step b/w engines and next energy source that's capable enough.

Batteries based businesses will do well for now but they should keep an eye out for new developments in energy sources for on time strategy changes.

Ugh. I’m going on for surgery next Thursday, for a laparoscopic partial colon resection, and one of the things I’m most worried about will be post-surgery pain killers. Hearing stories about excessive pain killer use and prescription really make me want to avoid them, but on the other hand I’ll need to be up & moving around ASAP to speed my recovery, and pain would get in the way of that.
I see your point now, and I largely agree with it. I do think that some of the same problems apply to Moore's law, though. At any given point, it could have been off by a significant margin and occasionally looked really dicey.

Basically, predictions are hard. :)

It I can emit a judgment that is now more visible: a lot of the less glamorous things mentioned there come from the Growth team.

As an ex-employee, I can’t say that I’m surprised. It’s never really subtle, too.

Antonio G-M (the author of _Chaos Monkey_ where he details his experience as the PM who started Custom audiences) joked today on twitter that Advertising has some bogger bodies buried. I’m not sure: when he left Custom Audience and related programs were a bit of a Far West. Most issues were rapidly addressed, some more recently. “Why am I seeing this”, facebook.com/ads/preferences and the more recent ad transparency for political campaigns show more integrity than anyone else.

I believe that Facebook could be (statically) profitable without the Growth tactics exposed here. The company was based on the express idea that they will be replaced soon, in a race, which makes slow expansion unacceptable. It was true up until recently, but I don’t think that it still is.
> According to DeepMind, AlphaZero uses a Monte Carlo tree search, and examines about 60,000 positions per second, compared to 60 million for Stockfish.

The previous statement was talking about how much faster and more efficient AlphaZero is, but the interpretation I pickup from that sentence is the opposite. Is this a “golf score” situation where lower is better?
no problem. I wasn't aware it was a duplicate. I just thought people should know. As one whom usually has to clean up the mess afterward, I just felt bad for them.

Wow! Now it makes sense how Dr. Rajendra Bothra was well connected in the Indian Bollywood industry. I personally recall big Bollywood stars opting to stay over his house during their US trip instead of a local 5 star hotel...mind you, this was back in late 90s. I hadn't heard of him in a while thinking he might've retired or died. This is a shocker that they're taking him down while in his retirement. Feds do not kid around!

Thanks so much for the kind words! And apologies for said incident. I think you might've been caught in a recently deployed intrusion & spam detection systems.

We've been battling crypto miners, evil hackers trying to launch attacks, and other nasty stuff. Of course, this is nothing new and we know how to deal with it but I think we just reached a scale where no other truly open computing platform has ever reached and we had to clamp down harder on abuse. Unfortunately, the systems are not very well-tuned yet.

Can you please email me some more info (amjad@repl.it) so we can debug?
I believe it (the Tesla battery plant) was built as a joint venture with Panasonic giving the IP and tooling and Tesla operating the plant. They're using a custom cell format also, away from the ubiquitous and standard 18650.

LG, Panasonic and Samsung make almost all the lithium ion cells used today so it doesn't seem odd that Tesla would license one of their technologies to start. The r&d savings would be in the billions.

FWIW: Accusations of bad faith with no backup are not generally good commentary.

As someone said, it was in peer review for a year.
That means it could not have been compared against stockfish 9 or 10 - they were not released yet.
As someone above points out, they used in-development stockfish versions as well (2 weeks before sf9 was released), and from what I can tell, they used the newest version they could have.

If you have some good data that means you can make this statement, can you please cite it?

Otherwise, can you please not make claims of bad faith?

What a load of sensationalist FUD.

MS are going to be using Chromium, the open-source project along with it's Blink and V8 rendering and JS engines as the basis for their next default browser. They are not planning to install Google Chrome as the default browser.

Microsoft choosing to use one open-source project over another to fork their next browser from does not threaten the health or diversity of the internet. It isn't giving Google any additional control or power over the internet, because Chromium is an open-source project and any integrations to Google's own services exists only in Google Chrome.

Basically this article is just Mozilla whinging because their project wasn't chosen and pushing FUD about the health and balance of the internet being threatened as a result.

In reality Google does not gain any "power" from this, unless you count the couple of contributions Microsoft have submitted to the Chromium project (which again, is open-source) as an increase in "power", by which logic Mozilla should already have more "power" because they have been receiving decades of contributions as a result of being the default browser in most Linux distributions (leading hackers to write Firefox contributions and addons instead of for Chromium for example).

It's not enough to just use a global salt.

You need to use a random salt for each user, which is stored in the DB.

You also need to use an algorithm that takes a lot of time - SHA1 and the rest are designed to be fast, on purpose. Use bcrypt or something.

(FWIW, PHP has the best batteries-included password functions i've seen in a language. `password_hash` etc just do the right thing. Copy what they do and you'll be ok)

Brigading, brigading. I keep seeing that word tossed around whenever people are unhappy that something inconvenient for them starts getting more attention than they think it deserves.

Personally, I'm happy that the media is finally starting to pay attention. Facebook has been doing shady, unethical, user-hostile stuff for a long time - since way before 2016. This has been building for a while now and I think the attention is entirely deserved.

I know very little about Brazil or Bolsonaro but one thing I read which shocked me was the statistic that 30% of the citizens of Rio were caught in cross fire in the last year [1]. If that's accurate it's mind blowing and really helps me to understand why Brazilians want a political change and somebody (perceived to be) tough on crime. It's like there are problems with the lower levels of the hierarchy of needs, and only after safety and stability are established will people care about the environment, liberal ideals, or fair treatment of people.

Not just data but also calls and text. Mother is on o2 and until about 6pm I was unable to call, was able to text her from about 4pm. Between 4 and 6 the calls were just failing with “called failed” and not even going to Voicemail, but texts was go though and I would even get delivery reports, just that calls wouldn’t connect.
