Slug aa is only 1-dimensional. From the paper (end of section 2):

> Adding and subtracting these fractions from the winding number has the effect of antialiasing in the direction of the rays. Averaging the final coverages calculated for multiple ray directions antialiases with greater isotropy, but at a performance cost. Considering only rays parallel to the coordinates axes is a good compromise, especially when combined with supersampling, as discussed later.

I.E. you don't get a real 2-d coverage result, only an amalgamation of a number of 1-d coverage results; and you must trade off performance and quality. Other approaches do not require such a tradeoff.

Analytic 2-d coverage can be done more cheaply than n 1-d samples (n is probably in the neighborhood of 4-6), and produces better (mathematically ideal, albeit with uncomfortable caveats) results. (Note 4-6 samples don't mean 4-6x slower, due to space partitioning, buffers, and other fixed costs, as well locality. And I think slug takes 2 samples by default as is.)

Everybody knows that building a competitor is not the hard part.

Elon could build and own 100% a competitor to Twitter for much less than the 3 billion he spent to get 9% of twitter.

The problem is getting the competitor to have traction.
For that you need to have the idea for a differentiator that will hook people, and unlike engineering talent you can't buy this!
How I hacked an ESA's experimental satellite
In a nutshell, whatever this article suggests, just don't.

This oversimplifies to a point where all learners learn the same way. They don't.

I don't even see the wider jaw in that cartoonist depiction, and I'd never recognize the man from it: a good cartoon will amplify features of someone, but this is a completely non-existant feature of the face being drawn. If anything, the guy has overly oval face compared to an average face.

So basically, based on the wrong premise, it happily leads you to a wrong conclusion.

A better take-away would be to attempt to recognize multiple ways to learn something, and make an effort to see what works best for any single individual. If you can't afford that (too time consuming, thus too expensive, to cater to each individual student), choose what you optimize for: having most kids learn to a particular (likely lower) standard, or having "most-compatible" (eg. in maths, those who kinda already have the mathematical, algorithmic, abstract mind) get the best of their talent. But you will be compromising either way.
Their cookie consent window is one of the most confusing ones I've seen:
"We use cookies for login, checkout and stats. Learn more in our privacy settings."

No thanks... I don't want to learn about your privacy settings? It's okay... store everything?
Manually! The CRDT itself is an event log. The client state is built from a secondary data structure which replays from the log (the extent of the "replay" determined by how much data needs to be merged etc)
By that logic the password itself is two-factor, because you need the database password as well as the database file to obtain the target password. I definitely see where you're coming from, but I'm not sure why you'd still bother setting up 2FA with backup codes then if you already consider the password itself 2FA?

A higher security level, which isn't needed for everyone indeed, would be to have these two things (where you have your password database unlocked, usually multiple times a day, and the second factor secret codes) in independent locations. This can also be two VMs if you keep the host encrypted and very secure for example. I assumed people with 2FA wanted to achieve a bit higher security level than all eggs in one basket. (None of these things beat a wrench attack of course.)
The safety issues are a red herring. It is the responsibility of the relevant regulatory authority to decide that not the manufacturer.
I want to print this out and frame it

Like all Cloudflare fanfare posts, it was to get a discount from Intel.
If you can define a problem, you can probably find a way to build a ML model that can solve it with enough examples. It's the problem definition that it can't do.

Also, I have seen some research e.g. on telling whether things are the same or different in an image. Like draw two arbitrary shapes side by side and build a same / different classifier. Last I heard, it doesn't extrapolate to new shapes, i.e. it is not actually learning "sameness".
Neither I nor my largest competitor are on the list, which is fair enough. However a now-defunct domain which my competitor previously used for their hiring portal is on the list. Weird!
If his plans are to turn twitter into an untouchable free speech zone, then twitter's in a world of pain.

We've seen from the past 4 or so years with QAnon, anti-vaxers, flat-earthers etc, that free speech to the wrong listener can be weaponised. If you make twitter censor-proof, all you'll get is a bigger trash fire.

I was sad when I got kicked off Twitter, but it possibly ended up being the best thing for me. Damn twitter is a toxic place... and if Elon turns it into censor-proof cesspool, I give the platform 5 years tops before it becomes yet another social platform that nobody uses anymore.
Then he probably is the biggest shareholder now. Based on public data Vanguard and Morgan Stanley were the biggest with about 8.5% each.

As someone who has been writing python bindings regularly for 10 years:

Writing bindings in Cython is much, much faster in terms of development time. It fits nicely and unintrusively in an already python packaged library. You can gently add some C functions or call C libraries in minutes.

You won't have a full control of what's happening though. Just have a look at the generated code and you'll see the mess of indirections that are generated.

Cython bindings become limited when you have to build more complex stuff though, going deeper than just calling some C functions. The typical case is when you have to actually handle the lifetime and borrowing of C native objects.

At that point, CPython will be the way to go, but it's much more code, and very error prone: you have to manually keep track of reference counting.

How is that a false dichotomy when that's exactly the choice this particular place has faced? No alternatives were available due to cost and non-existent gas infrastructure.

Not like we want to expand our gas usage anyways as here we buy it all from Russia, right?

The law is really strict. If you look on reddit.com/r/ukpersonalfinance there's loads of people complaining that Monzo have frozen accounts and won't tell you way. In pretty much every circumstance, the person involved has been moving large amounts of money around through Crypto, so it's fairly obvious why they might flag that up as potential fraud/money laundering and cause an investigation.

Cookie warnings have got worse and worse. There are sites now that list 200+ checkboxes with a handy "reject all", but if you don't click through to the list of "legitimate interest" sites you miss out on rejecting 200+ more advertising partners (who somehow have "legitimate interest") with no reject all option.
That's a wrong take of my opinion.

It's better to use energy at times of overabundance for something economically useful (money to make the renewable project cheaper = affordable), than to just throw the energy away. If Bitcoin can make renewables more economical, we can stop burning fossil fuels faster. And if Bitcoin causes coal to be replaced with anything, that's a win for the environment too - even if it's a net increase of energy usage and heat, it's still a net decrease of greenhouse gas production which is much more important that reducing energy usage.
It actually works the other way around too - moving from Windows to Mac is a pain because of the shortcuts. It was a challenge to overcome in many aspects, but one of the most annoying things is that there is no keyboard shortcuts for navigating application menus. That still bugs me very often.

Edit: spelling.
Well yeah, you have to actually compete in a competition. Seems pedantic to me.
TWTR is up 24% pre-market.

I don't think there's much that Musk can do to increase Twitter's revenue, but at least the market seems to believe that he can hype this one beyond reasonable valuations, too.
If it was painfully obvious, there wouldn't have been 10 years of debate and new projects wouldn't be coming up and wouldn't be successful.
I agree actually, but the specification was "solved". I don't think AI has solved anything. It might be good at a couple things, but that's not what was asked.
The worst case is the trains stop running for a while, which it sounds like is what they pre-emptively did?
While it's true speed was not a priority, I think most of those initiatives didn't try hard to work with upstream.

The Microsoft funded project is different, they're merging things. I don't think they've started on a JIT translator yet, though, last time I looked they were busy picking lower-hanging fruit. From watching their communications, I think they might get there at some point.

It's not as simple as just emitting machine code, though. To get something in the same magnitude of typical C code, you need to deduce types and peel away the boxing and unboxing layers.
> The problem is getting the competitor to have traction

The mere fact that the platform belongs to him can help a lot
Which is a good thing because it ensures you at least don't hire someone who you should not have.
What's the average age of a Barclays or TSB user vs a Monzo user? According to this, 72% of Monzo customers are 18-35: https://www.businessofapps.com/data/monzo-statistics/

If that's the case, it's fairly obvious why there'd be a lot more noise - a lot larger percentage of people in that age group doing crypto, and a larger percentage are "very online" and likely to complain about it there.

Wow a rare rpg reference. Everyone mentions COBOL (still rare) but you almost never see a reference to rpg anymore.

I spent a few years early in my career (early 2000s) coding in rpg for a casino and a major bank. I’m still impressed with myself that I was able to get my mind wrapped around the column nature of rpg.

One thing I do when I want to make a selection of similar photos is to sort them by size (in kilobytes) and keep the largest one(s). That selects for the photos with the most details.

I don’t advocate automating that, though. You still want to at least glance at all of them because there may be a technically inferior one that jumps out to you.
Google: Raise Your Data Center Temperature (2008)
I assume that much of this neat stuff was attempted in the 60’s onward by clever people working with willing hackers with pathetically underpowered hardware (but the rooms were kept warm). Spacewar, Eliza, all of the stuff from MIT and other places, protein folding on a pdp-11/34 in 1978. These people knew of no limitation other than hardware and their programmer’s ego was big enough to code around that.

Hacking is a field that has little awareness of its history. Maybe it’s because it’s so new or maybe because the iron is infinitely better than it was or that programmer’s ego remains strong. But people aren’t smarter now, the sheer mass of developers has moved the talent peak to the left, and too many people code it faster rather than better.

50+ years on, coding languages and environments look the same, system reliability isn’t really different and software still runs slowly. Hell, “the cloud” must really piss off oldies who remember Xterminals, Suns and big iron’s ability to checkpoint and move jobs across the globe to use 2nd and 3rd shift hardware.

Y’all got virtually infinite resources now. Please make sh*t that’s at least as stable as an old Volvo.

You're taking two qualifiers that I assigned to different statements.

Images are not a reliable way of getting information on ambushes. There is no way to know if those losses were during ambushes or shortly after the initial advances. Moreover, a big reason the OSINT community had such an issue with cataloguing them is because it was often difficult to tell whose it was and whether it was already accounted for earlier.

They indeed sustained a high level of attrition. And yet, it was still a sustainable level of attrition. Russia is lacking soldiers that are needed to attack more than they lack equipment at this point in time.
> And as the last step after removing the malware, I took the opportunity to install uBlock Origin on my partner's computer. I'm sympathetic to website operators who want to support their free sites using ads, but these ads are often malicious ...

Exactly. this is why I will never side with LTT's "adblock is piracy and hurts creators waaaa waaa" bullshit. Ads are more often than not malicious, using clickbait to get people to.. Click on them.
I can't think of a single thing on this list that is "solved."

Your first example (FB/YT recommendations) is literally tearing our society to bits at the moment.
Searched and I can't find any. I did, however, find a Which? article that says "Resolver found almost three-quarters of complaints about frozen bank accounts mentioned ‘digital’ banks".

Statistically it doesn't seem likely that Monzo and its ilk would be so overrepresented merely because their customers are more fazed than others about having their money taken away. Still, if the FCA have published meaningful statistics I could be proved wrong.

Thats not a trick, every version of software eventually reaches EOL. Thats why there is semantic versioning, etc. What do you think happens when security vulnerabilities are found in a version of software. Your comment is meaningless.
That's exactly the behaviour I have when using iOS.
I was asked to resubmit this new edition that I announced in HN as it got finished on 2019-04-25: https://news.ycombinator.com/item?id=19745517

The process took around a month in my spare time, and involved copy-and-pasting the OCR plain text, then marked up as DocBook XML, then converted with my own XSLT stylesheets into HTML5. There were many transcription mistakes, some from OCR from the 35 year old daisy-printer monospace printout, some were in that printout because of electrical noise in the printer serial line in 1986. I fixed those I found by hand, then a couple of readers have reported others.

Since then I’ve corrected more OCR errors, and polished a bit more the HTML rendition.

From the introduction to this edition:
“It features an instance of Douglas Engelbart’s implicit links, automatically linking all appearances of certain terms to their definitions elsewhere in this document. This is done through a Javascript function that operates on the HTML content from the web server. It also shows his structural statement numbers, those little labels to the right of each paragraph that allow high resolution linking.”

Doug Engelbart was not part of Xanadu, although he was a close friend of Ted Nelson for decades. It’s just that those aspects of his NLS (of 1968 “Mother of all demos” fame) fit well this document, and work relatively well on web browsers.

I did try to implement transclusion as an example, but the target web server did not provide a CORS header and browsers refuse to load their content.

This document goes into detail about the addressing scheme for documents (https://sentido-labs.com/en/library/201904240732/Xanadu%20Hy...), the enfilade data structure (https://sentido-labs.com/en/library/201904240732/Xanadu%20Hy...), their then-future plans, etc.
Military help sent from West to Ukraine is at about 1/30 of military equipment sold by Germany and France to RF.

> Maybe if we paid those who teach better, we'd attract the best of the best to teach.

I agree struggling for basic survival as a public servant is not ideal, but be careful not to turn education into a lucrative opportunity where people come for money not passion.

Money is certainly not the only way to attract talent (though teachers still need to pay their bills) and in most schools i've attended the talented teachers were just ridiculously hindered by the bureaucrats defining their program and agenda. David Graeber's talk "Manageurial feudalism and the revolt of the caring classes" comes to mind.
How to Convince People to Leave Homes at Serious Risk from Climate Change
If I have understood it correctly, the average risk of not taking vax per age is like average risk of smoking. So, what ages the risk is smaller for?
Might not be enough, since some viruses are using firmwares and other things to be made more difficult or impossible to remove properly, if you can remember the story about HDD firmware being infected. Rootkit have been existing for a long time now.

Not to mention the intel management engine thing, wifi firmwares, etc.

I believe in the conspiracy theory that computers are now built with low security in mind, to make it easier to compromise by 3 letter agencies, as long as those 3 letters agencies are holding supremacy in the cyber weapon warfare.

This still enables a few rogue black hats to lockpick those vulnerabilities every once and then, until most of them are caught and neutralized (either sent to prison or forced to work for those agencies).
These calls for unity and bipartisanship are precisely the wrong approach. In time of crisis there are certain issues that need to be solved one way or the other.

The US should effect regime change in Russia or it should not. Housing is an investment vehicle or a necessity for life. Wokeness is a strategy to fight systemic racism or a strategy to divide the working class. These are all reasonable but incompatible positions.

The government must choose one and go forward to see how it works. But bipartisanship is just limping on both legs.
Gonna depend a huge amount on what you're doing to be honest. I used it for physics modelling codes and it made a bit of a difference (comparable to Numba) but dropping to C for the main computation routines was what we ended up doing, and that worked very well for us.

It's very fast to write for, that's the main benefit. Use it together with profiling and just pick off the slowest part first.
I don't understand the causality link you establish : "because human are 100 watts space heater".
Are you saying that because humans produce heat, running out of resources is not really a problem?
The really huge issue with SSE, and the reason why it’s historically been dismissed, is that it us subject to (and counts towards) the HTTP 1.1 domain connection limit.

Sadly that makes it a bit of a pain in the ass to manage for sites served as (/ compatible with) http 1.1.
You would not be able to get such a perspective from Russian media. They aren't saying that the Russians abandoned Kyiv and are repeating like a mantra that they "will achieve all objectives", whereas I just wrote that they are falling back to the Donbass.

I also don't see how it's optimistic for their side to say that they are runnning out of soldiers and have to redeploy.
And what kind of metrics can you use to determine whether someone teaches well? Whatever metrics you use, there's probably ways to game the system without providing better services.
Yes the law compels them to be like this. It’s actually criminal to tip someone off they’re being investigated.

Perhaps the law is too strict due to the impact it can have on individuals.
He sat in a Joe Rogan podcast twice. Tim Pool told him exactly what he needed to do.

https://www.youtube.com/watch?v=DZCBRHOg3PQ

In the last 3 years, what exactly did he do? Nothing. The situation got significant worse.

Worse yet, because of their size they are 'too big to fail' and so they flagrantly allowed to break the law and violate free speech? Section 230 liability protections limits their ability to censor. Twitter is certainly in violation of Section 230. They simply need to stop doing this. That's it. Fire any twitter employee who isn't a free speech absolutist.

Eventually Twitter will hit the wrong topic to censor and they will collapse so rapidly just like digg and how many others. I am very surprised it hasn't happened to date.

Hunter Biden's laptop is real now? Censored on Twitter because it's 'hacked' or illegitimate or whatever. How many Trudeau Tyranny trends have been censored for no valid reason. We are counting.

Meanwhile, the givesendgo hacked information of freedom protest donors was not only allowed... it was bumped up into trending. CBC covered it widely. Government then used hacked data to seize people's bank accounts.

I dont see parler/mastodon/gab as true alternative to twitter yet. Twitter can fix themselves. They can move into compliance with Section 230. They can return free speech to their platform. If someone comes along to hostile takeover twitter and makes this change... they are going to be worth a trillion $.
While it is not the only driver, a major early driver for integrated circuits was the need for reliability in military electronics. I saw an estimate that at one point 1/4 of all carrier based aircraft were out of service at any time due to avionics malfunctions. And the first major user of ICs, the Minuteman II guidance computer, would not have been possible without them. The Minuteman I computer was smaller and used discrete components, and could only be made sufficiently reliable by enormous testing and retesting at multiple system levels. Doing the same for the larger MM II computer would have been entirely too expensive.

ICs increased reliability by making interconnections far more reliable (being deposited on the chip together so failure is correlated.) Of course they are also smaller and use less power, but reliability was more of a brick wall issue.
