Win32 has fibers, which are essentially green threads. And for a while, .NET itself tried to support it. The problem is that there was never widespread support on the native side of things, and in .NET itself, user code has to not make certain assumptions to allow for fibers to work (e.g. that each managed thread maps 1:1 to an OS thread), which in practice nobody followed.

This points at the bigger problem that every implementation of green threads has: it breaks interop unless everybody buys into it. Async/await is fundamentally callback-based, which can be represented nicely even in C ABI - so literally any language that can interop with C, can interop with an async/await model, with execution flow asynchronous throughout the entire chain. Runtimes that choose to roll their own green threads, like Go, and I guess now also Java, are effectively stating that their convenience is worth the inability to interface well with async code outside of their runtime.
Getting it into the 26 hour range is important for take off and landing. I haven't seen details, but you'd likely want to leave New York at 3:00 AM and thereby arrive in LA at 2:00 AM, avoiding the heaviest city street traffic. I know from personal experience that roadways are the lightest overnight Sunday-Monday. Maybe depart on Sunday 3:00 AM and arrive Monday 2:00 AM.
really nice, thx for share!

Twitter is not just incomplete/out of context thoughts. It can be. But not always. Follow the right people. I find it’s great for Javascript patterns and new findings. Of course the content is not discussed in great detail but you can get a quick jist from various sources.
The same with instagram for photos. I much prefer to see photos in series but quick snapshot from various sources in one platform.
This is what’s destroyed blogging mostly in my opinion, you can micro blog quickly.

I'm convinced that the markets, which, let's remember, were high on the hog all throughout the obvious impending catastrophe of this virus sweeping in from the east at the beginning of this year, until the moment reality was shoved in their faces in the form of an outbreak in Italy, have not yet absorbed the enormity of the long tail of this pandemic and the lockdown.
It's strange how in other areas such behavior is encouraged. Where is the anger when people try to set speed records on boats? Every time some rich idiot gets into trouble on the high seas, other people have to risk their lives to save them. Setting aside rescue personnel, many innocent bystanders have also been killed by racing yachts.

2018: "One Fisherman Killed, 9 Saved After Boat Collides With Ocean Race Yacht"
https://www.youtube.com/watch?v=Mjrq0NDL8r4

"On the night of 19 March 2007, while around 22 kilometres (14 mi) offshore from Guatemala, Earthrace collided with a local fishing boat. No Earthrace crew were hurt, but one of the three crew members from the fishing boat was never found." https://en.wikipedia.org/wiki/MY_Ady_Gil#2007

2012 "A yacht involved in a race off the coast of California and Mexico apparently collided at night with a much larger vessel, leaving three crew members dead and one missing, a sailing organization said early Sunday."

And if you want to compare statistics, how many people died on Titanic as it was racing across the Atlantic? Including that tragedy would probably make ocean racing more dangerous than the cannonball run even on an hourly basis.
That’s true, but I felt the need to call out the nervous system component of the picture.

Green threads have been around for a very long time before Go, and there's nothing specific about Go that made them solve any problem they didn't solve before. It just so happens that this is a solution that comes with many downsides, which is why it's not universally adopted.

Indeed, Java itself had green threads (only!) in the first couple of versions.

It's way more mature. I just spent a week evaluating Pulsar vs Kafka for a client and the fact Kafka has been open sourced for 10 years vs. Pulsar's 1.5 really shows in documentation, community support etc.

> what happen to your data if x+1 server permanently fail in the cluster with a replication factor of X.

It depends on how many in sync replica sets existed entirely within those X+1 servers. Their partitions will go offline, and other ISRs will have underreplicated partitions, and the alerting you've set up as a good engineer will have told you this was happening.

> what happen in multi-tenancy scenario to other user throughput and latency when one user try to use all the capacity of the cluster

Nothing because you're using ACL and have configured quotas appropriately.

Bad things otherwise.

I think it's probably a function of how big the risks are to themselves vs. others (both relatively and absolutely). I don't think ocean yacht races are as dangerous to bystanders as pirate road races are to even an order of magnitude, probably several.
They did have to - that's the entire "outside" ecosystem, in which any app has to live; system APIs, commonly used libraries etc.

This is partly why the Go library ecosystem insists on rewriting everything from scratch in Go, instead of wrapping native libraries.

Huh, might finally get around to Apple garbage. Closing your users to one internal system with internal hardware works for speed and maintenance issues([with users] look at early Windows with it's struggles and blue screens despite it's prevalent use across various hardware systems. But it doesn't work with devs. Dude if I can't code your stuff or for your platform on my shitty little linux, I have zero interest in working on your platform or utilizing your tech stack.
You are just reasserting the same thing without backing it up in any way. Saying something shouldn't carry any moral weight is not a moral judgement because who would it be judging?

Correcting someone about is not casting a moral judgement. Saying a piece of a system meant to create and capture some value doesn't need to be ascribed good or evil is a statement that can be taken at face value. Trying to say everything is a moral judgement that someone else is creating a false dichotomy is just projection.
Sweden and Norway were "tied" a little while ago. Not so much, now.
That's a good point. It is not political suicide for those leaving politics. But it is political suicide for those that are elected or want to be re-elected.

For example, Bush Jr left the economy in a mess but he was a 2 term president with no political future. So Bush Jr is fine, but Obama who was elected and who wants to be re-elected has to re-inflate housing and stock prices. That's why the housing prices and stock prices won't stay low for extended periods of time. That is until we arrive at the limit of our growth/expansion when no political or economic measure will do any good.

Author here. That is good criticism! Thanks for bringing it up. I didn't consider other factors like ease of sharing.

They are definitely tradeoffs. At least for my personal website, the size disadvantage of GIFs still outweighs them, in my opinion. I think bandwidth usage and battery drainage are also worth thinking about on behalf of the user.
I've never understood that argument; why would an acronym need to preserve the exact sounds of the letters in the original words? I don't think it's very uncommon for them not to. "UNICEF" is not pronounced "yoo-ni-chef", "POTUS" is not pronounced "po-thuss", "OSHA" is not pronounced "oss-huh", etc.
Damn, I really like the concept of creating blog posts simply by sending email. Solves a lot of UI problems.
That is correct: Pulsar uses ZooKeeper relatively lightly and only for things strictly necessary for the cluster to run. Everything else (message data, topic info, cursors, schemas) is stored in BookKeeper.

Would still be great to see ZooKeeper made superfluous, though.
I am surprised that deleting Facebook led people to socialize offline more. After I deleted Facebook about seven years ago, my social life took a big dive because I was no longer getting word of events that my friends were organizing – they would solely post the announcements solely to Facebook. Now I am wondering if this doesn’t happen to people today because Facebook is increasingly passé, and so all those event announcements are going over Whatsapp instead and no one is deleting that.

But even today, without Facebook it must be difficult to hear of many general events happening in one’s city where one could make new friends. Meetup.com used to be a great platform for this, but where I live or in the cities I travel to, it has been reduced to either lecture evenings for software developers or thinly-veiled ways for yoga teachers and entrepreneurs to build businesses off of the people who show up.

Another vote for TablePlus. Really solid and support for tons of other DBs. Came from Navicat which crashed a lot. Pricing is way better too. They also make DBngin, a great free tool for spinning up local DBs in a clean, self-contained way.
I sort of wish I had a better hobby than reading hacker news. Today I saw a house for sale, built in the 80s, lots of outdoor entertainment stuff for neighborhood parties. Vacant, crumbling, dead. Reminded me. Kids, seriously, this used to really happen. Every day, all the neighborhood kids would play ball games at somebody’s house, and the adults would walk over for about an hour and talk to each other. Adults all tried to outdo each other for the nicest house and best backyard for this kind of thing. Nobody does this anymore. Might as well buy that trailer in Space Park Way and a VR headset. I always thought RP1 was so banal; I was hoping for a more nuanced and unpredictable dystopia.

Detroit, the city with the most violent crime per capita in the US, has also now been ravaged by covid-19. Most of the residential neighborhoods in Detroit are fucking terrifying for ADULTS. These guys are cutting grass in public parks so poor kids have something to do. They should be applauded because poor kids will have a place to run around and laugh for the first time in months because of volunteers.

I have seen some comments here complaining about wildlife not having a place to live close to humans.

You know what else thrives in high grass? Ticks and rats. And if a lot is abandoned too long in Detroit there's a good chance it'll accumulate dead bodies.

Screw your wildlife.

Pulsar itself is solid but it’s true number of good clients is limited. Same is true for kafka the only reliable client is the java one. All other are based on librdkafka which still have many major bugs causing it to be stuck and not producing to new leader during leader changes.

One benefit of pulsar is that the client library is completely stateless and much simple. It does not need to know where data is stored it’s all handled by the pulsar broker.

I think there's a chance this can happen when AV1 starts to gain adoption. Webp had a chance - you can have well encoded, looping video in a .webp container that operates exactly like an image. The issue was lack of adoption - it never took hold due to Apple not adopting it in their ecosystem. AV1 has support from every major player in tech, and .avif images support gif functionality just fine.

Until that happens though, I just don't see .gifs ever losing traction. I still need to upload gifs to slack if I want autoplaying/looping behavior without user interaction, I still need to embed .gifs in my confluence pages, and when documenting user interactions in github readmes gifs are still king.

FWIW I've made a small user script for encoding gifs in a two pass approach (as most gif encoders I've seen do a pretty shit job). If anyone wants it here's the script: http://files.jjcm.org/gif.sh

(to use, just type `./gif.sh -s=SIZE -f=FPS input.mp4 output.gif`)
What about to post exactly the same sentiment. I'm finding it hard to access the full study, but I'm guessing "less knowledgeable about current events" means the treatment group weren't as aware of the various disconnected things the media puts in the faces of their audience and then drops within a week, reducing the events to mere trivialities.

It's (at least usually; it sounds like this guy is doing something non-standard) meant to give you the intuition of a path through a space - a line from point a to point b that possibly wiggles about a bit in between. Formally it's a continuous function from [0, 1] to the space that sends 0 to a and 1 to b - so if p is a path then p(0.5) is "halfway along" the path, p(0.25) is a quarter of the way along the path, and so on. The concept of a path in the space {true, false} is kind of trivial - any function into that space is (topologically) continuous - but the intuition should be something like a path between two points on a 2D plane.

Your preference is legitimate, and art will always be subjective. I think a big difference is whether you’re trying to show a photo in low res versus do art manually and use pixels as your brush and embracing the limitations. Anti-aliasing is typically a post-process. There are examples out there of careful and manual use of intermediate values in pixel art to make an edge appear smoother, that’s a type of antialiasing. It’s just rare to use more than that and call it pixel art today, because general anti-aliasing makes the image blurry or muddy, and it doesn’t really leverage the pixels, it just works around them.

Good pixel art reminds me of the lego TV families: https://imgur.com/gallery/Cz3zR. It’s such good concept art precisely because it’s as blocky as possible, yet somehow still completely recognizable.

I don’t know if that Sarge cats image is manual anti-aliasing or a more automated process, but for me it doesn’t draw me in or demonstrate a broader emotional range, as you say, compared to some of these examples:

If there's a GPS signal then it may be possible to use the differential phase satellite between two phones to get relative position down to a meter or so (kind of like a super crappy rtk taking advantage of the pps stabilițy). Not sure the gps devices on phones expose enough information for this. Differential rssi of cell/wifi networks is another indicator but probably not very accurate.

Work from home for instance, many companies never wanted to even try it, even if it could save money, but now they’ve been forced to try it and actually like it, thus it will become a new status quo as people come out of quarantine and realize what a drag it is to actually have to leave their new habits and go back to shitty routines.

As a Spaniard, that's exactly how I would pronounce those acronyms. Time to learn a bit more about English :)

Funnily enough, in Spanish "gi" is pronounced "ji" as in "Girar" (pronounced Jirar), while "gui" is pronounced like "gi" and "güi" is pronounced "gu-i". But "GIF" in Spanish is still pronounced with a soft "g", contradicting the general rule.
