Crypto-"currencies" are relatively new - and many including myself see them as innovative Pyramid-Ponzi schemes. There's also clearly a lot of VC money involved now, and other less savvy people's money in them - the army of HODLers, so the SEC has to tread carefully.

Would you prefer - would those companies prefer - being completely ban/blocked from operating until SEC understood it all? I'm guessing no. I'm guessing too that investors would have liked the protection though, as would society in general - those who got drawn in by the shallow hype and lost money.
3. If your writer thread dies randomly, then your reader thread has nothing to do.

3 part 2: If your reader thread dies randomly, then your writer thread eventually fills the buffer and has nothing to do.

Both cases turn into a deadlock with this "lock-free" buffer. You can't afford to have either thread die, regardless of the "lock free" or "locked" implementations.

> 4. Lock-free will not stall all other threads if one of the threads stalls in the middle of an operation.

Same thing here. The queue will eventually fill up if there's a stall, causing the reader (and / or the writer) threads to stall as well.

So in practice, neither #3 nor #4 actually help you out.

Because telecom companies aren't censoring their political opponents.
I almost agree with you. But I think it was fair fear-mongering on both sides (the scientists vs the politicians). It really drove home that secrets and cover-ups were the real disaster. People were afraid to admit their failure. I like to think that today, with cameras and social media everywhere, secrets and cover-ups about a disaster like this would be even more impossible (it was impossible to cover up even then).
As someone who develops a DAW, that's really not my experience. With the very same soundcard (so far RME, MOTU, Apogee) on the very same hardware, I get consistently lower latencies on Windows with ASIO than CoreAudio.
> I had the feeling the car was being lifted up due to the air currents.

Yup. It is a bit similar as in a plane wing: In a wing, there is an airflow below the wing, and another airflow above the wing. The wing is curved so that the air flowing above needs to travel a longer path, therefore it travels faster. Faster travel translates into lower pressure, therefore there is a pressure differential which lifts the wing up.

This is similar for a car, which is curved as well. Only, because the bottom side of the car is relatively close to the ground, there is less airflow which increases the pressure differential upwards.

This aerodynamic feature is also the reason why racing cars have features which cause that the airstream presses them into the ground. Without that, it would be easy to lose control.
> I still don't understand why they didn't get SEC approval before offering the token sale, however.

Because what they did was illegal and the SEC would never have approved it. To do it legally, they would've had to only sell to accredited investors and there's no way they raise $100m doing that.

Then schedules out the other thread?

I mean, what happens if the writer thread stalls out in the lock free case? The reader thread runs out of things to do and is also going to be scheduled out (eventually).

Like, that's the OS's job. To remove tasks from the "runnable" state when they stall out.

> That's why people write lock-free - they don't want a stall or death of the one thread to stall other threads.

Erm, if you're saying that the reader thread will be highly utilized... that's not likely the case if the writer thread in this "lock free" implementation stalls out.

Lets say the writer-thread hits a blocking call and is waiting for the hard drive for ~10 milliseconds. What do you think will happen to the reader-thread? In the "lock-free" implementation talked in this blog.

Our data shows "Amazon Choice" is essentially a join table between product and search keywords, ordered by a multiplier of conversions, ratings, and availability.

- Customers are happy when they get stuff fast - it needs to be available right now, and in the buy box

- Higher rated items are theoretically better than lower rated items

- "choice" badge is keyword specific: a plant light could be choice for "grow light bulb" and "grow light led" but not for "light bulb".

Our data shows the items are not correlated by margins for. We often see negative NET PPM on "choice" items.

The WebRender team seems to be rolling out very gradually and is, if I remember a recent blog post correctly, restricting based on specific GPUs and specific platforms that are proven to work without e.g. crashing or breaking out various things (like window toolbars).

If you set these options, and then later on, you find that your Firefox is super buggy and won't render anything properly and has weird crashes, it could be because you set these options — and it might take hours or days to realize that.

(And then reverse them, somehow, assuming that gfx.webrender.all hasn't broken about:config!)

I don't know if that is down to recency bias, but rather the sheer number of fans for that particular genre. There are not many movies in the top 50 you could reasonably make that same argument for.

> spinlock=false; // Don't even need an atomic here actually

No, you'll need a memory barrier there. On x86, sure you get away for free, because x86 memory model says stores are never reordered with other stores.

On practically all other systems you'll need equivalent of C++ atomic "memory_order::release" to prevent stores from being reordered with other stores.

Otherwise you're in for a surprise. Without a (half) barrier, it'll be buggy on ARM, POWER, MIPS, etc.

Edit: I see you added the barriers. Sneaky. :)

That Bloomberg headline is itself egregious. Who is Chosun? That Chosun Ilbo is a right wing propaganda tabloid with a reputation for making shit up should have been mentioned in that headline. 'Headlines that seem plausible with details hinting at fabrication in the article' is a bad formula and deserves to be criticized.

In fact, Chosun Ilbo's reputation should have prevented the story from being republished by western media at all.

Ask HN: Do Press Releases still matter?
Back in the day, it was a great way to get some SEO juice. I am aware this is not really working anymore, but can you get press and bloggers interest in your startup by sending PR? Are Press Releases read by people looking for news and stories? Is it worth paying $300+ to one of those PR distribution websites?
Yes, good point.

The obscure details are always hard to remember... that particular example is x86 specific.

I probably should edit in the memory barriers.

Yeah it keeps running, exactly as you say! It can keep working on jobs already on the queue independently.

Are you arguing that you you personally don't think it's worth doing lock-free for various practical reasons? Or arguing that's never why anyone does it?

Because the latter is simply false - I've done it for the latter reasons professionally both in academia and industry so there's one data point for you, and the literature talks about this use-case extensively so I know other people do as well.
that's hilarious.
You still have to fill it. It would probably be easier to fly 3 or 4 A321LR instead depending on demand.
Yes, it is indeed a little puzzling. CrB's biggest benefit is to people not interested in engineering their own scaling/sharing solutions for existing RDBMS options or if they care about optimal resource utilization (under a certain subset of conditions), neither of which are particularly draws for the AWS team. Perhaps they are more worried about other vendors.
Bing was caught getting their search results in part from google and their response was "who cares". Last I checked Duckduckgo got their results from other places like bing and yahoo (who also uses google's results). One way or another, google's results are what you're getting no matter who you're using it seems.
Incredibly dubious. I have found user ratings for things that draw 'passionate' fan bases (movies, video games, etc) to be nearly useless over the last 3 to 5 years. Review bombings are becoming all too common over issues that more often then not have nothing to do with the actual product.

Luckily, I haven't really seen this with books yet (at least on Goodreads), but I am sure it has just as much potential to be hit in a similar way.
I worked at Valve a few years back, and I could write a book about what's wrong there. I think the biggest problem they have -- which the author of this article touched on -- is that "success is the worst teacher." Valve have discovered that cosmetic microtransactions are big money makers, and thus every team at Valve was dedicated to that vision. When I was there (before Artifact started in open development) there were essentially no new games being developed at all. There was a small group that were working on Left for Dead 3 (cancelled shortly after I joined), and a couple guys poking around with pre-production experiments for Half-Life 3 (it will never be released). But effectively all the attention was focused on cosmetic items and "the economy" of the three big games (DOTA, CS:GO, and TF2). One very senior employee even said that Valve would never make another single player game, because they weren't worth the effort. "Portal 2," he explained, had only made $200 million in profit and that kind of chump change just wasn't worth it, when you could make 100s of millions a year selling digital hats and paintjobs for guns (most of which are designed by players, not the employees!)

I joined Valve because I excited to work with what I thought was the best game studio in the world, but I left very depressed when I found out they're merely collecting rent from Steam and making in-game decorations for old games.

The show is great, and it reaching this level of notoriety is amazing. Yet, it just goes to show you how everything is marketing and timing. If this show isn't on HBO, and isn't following the exit of Game of Thrones does it even get noticed? For example, The Terror, which in my opinion is just as good as this show (and features a better performance by the same actor in Chernobyl) was not only ignored by viewers but by critics alike. TV Critics are, in my opinion, completely useless and only ever write articles about popular shows. Best of lists you usually see at the end of the year make me wonder if these people even watch the shows.

> apolitical

I don't believe this is possible for something as wide-ranging as the effects of increased climate change.

Every paper that attempt these estimates use a 'local' projection of (predicted change) * (current prices to mitigate those changes).

But even ignoring the huge error bars around the scale of changes we'll see, the large-scale changes that reach across all of society will also change all the prices as well; not to mention it's not easy to predict far future prices anyway.

This also ignores the fact that the marginal impact of a ton of CO2 in the future depends on how much CO2 is then in the air, which means you're now in the realm of predicting what current politicians will do ... which is inherently political, since it'll make some people look good or bad.

L1 caches do a LOT of book-keeping for you

Again, this is all done automatically, because programmers want to have their data look the same from all cores (for some definition of "looks the same").

In terms of bookkeeping examples, we have to make sure we're not inadvertently causing False Sharing.

https://en.wikipedia.org/wiki/False_sharing

This sort of thing is quite implicit as opposed to being explicit. This is because communicating with a caching+coherence mechanism is a bit of a kludge.

When one cache claims "exclusive access" to the data, no other cache will write to it (although they may read stale versions of that data from their own cache).

Get your head out of CPU caches and low level stuff for a moment. Imagine that someone proposes a high level communications protocol to you which acts like this. That would be ugly. That's the sort of mechanism you'd expect to see at a very low level of the networking stack. That's precisely the sort of thing a programmer wants abstracted away from them, so they can think of communication as communication, not as a series of details about the behavior of hardware.
If it helps with increasing resource allocation to the project it can be a good move for the world as well. Currently resource allocation is sponsored by VCs, but this can't continue forever.

Hmm, looks like an x-plane screenshot. It wouldn't surprise me if they've been prototyping with planemaker (included with x-plane).

IMHO interesting concept but the thing to be investing in would be electric engines (hybrid or battery) as that will cut fuel costs a lot more potentially. 20% is an incremental improvement and potentially not good enough by the time this gets productized and never mind the time when this gets retired a few decades later (in the best case). So, in short, I think this won't fly (bad pun, sorry) because it's not anywhere near good enough by the time it can reach the market (15+ years?).
Uhhh... now it is :-)

Why are we satisfied with Sign In with <Big Company>? Shouldn't this be an open standard? I mean, I know open/federated identity systems have failed several times, but there's no reason why we can have a spec where your device or browser generates per-site credentials and stores them in some encrypted replicated storage. And for email-relay, that's been going on since penet.fi in the 90s. Email is already federated, and there's no reason why you can't use third party email anonymizing services.

> The underlying issue here in this one is that people (apparently so far!) want to use AWS/GCP/etc more than they want to use mongo, redis, cockroach, or any particular technology. No license change will fix that.

That's a really extreme way to think about this.

Consider this example: I lose 1 Utility Point for every new provider I need to contract with, set up monitoring for, set up billing etc. This balloons to losing 2 UP if that provider's in a different public cloud, but since many let you choose an AWS region, this is probably not a problem. I gain 5 UP from using Cockroach, because it saves me engineering time. And I gain 1 additional UP from using latest Cockroach because they're making real optimization breakthroughs.

So pre-license-change, AWS Cockroach that tracks the latest release might net 6 UP, and Cockroach Cloud run by the company might only net 5 UP because of that cost of a new provider.

But post-license change, Cockroach Cloud would be tied, because now I'm comparing the cost of a new provider against the cost of latest developments. And every single blog post I see about Cockroach developments pushes me in that direction.

It's a really great move, though kind of a loss to open source. I wish the Cockroach folks the best.
