Reminds me of when I showed up at SFO for my 2nd business trip to Australia, about 90mins before the flight. I had been unable to check in online (united's site gave me an unhelpful error) but I didn't think too much of it.

The kiosk at the airport also balked.

When I went to talk to a human, he casually asked me if I had a visa/ETA. This totally perplexed me as I didn't remember having to do anything in the past. He told me I'd just need to fill out a web form and "they usually approve it within an hour".

Minor panic while I tried to fill out a complicated web form on my iphone at the airport with shaking hands. Ultimately it was approved within about 20 minutes and I had no issues with my flight. Lesson learned! I guess on my previous trip I used my company's travel portal and it must have done the ETA for me automagically, so I never had any awareness I needed such a thing.
Misleading title, ETIAS is not a visa and it not directed at Americans as it applies to 60 countries including Canada, UK, Australia, Singapore, and South Korea.
Using the trip counter isn't the same as entering the destination in navigation. If you tell navigation your destination it will tell you if you're going to make it or not. If you start driving like a madman halfway through it will reevaluate and start navigating you to a charger. I rented one for a week and took it up into the mountains, far from a charger. It was scary, but we made it back with 17% charge once I stopped passing everyone every time there was a dotted line.
> At the heart of ETIAS is an electronic database system to better track who's coming and going.

Lots of people online annoyed at having to pay a fee (7 euro) to travel but this is what it's actually about.

Curious to know if EU governments are limited in what they can currently do with passport entry/exit data and if this expansion allows them to do more?
Ok, so what's the actionable take here? Are people going to use this to try and push wealth redistribution and authoritarian controls which is about the only thing I've ever seen from "climate action" types? Or does this imply those wouldn't work anyway now? Is anyone or any government going to look at actual motivations to help live in a warmer place? And/or to pull carbon out of the air, or get more nuclear, or whatever else we need to keep living normally?

It's going to be hard to get people to care about this if the takeaway is going to be "other people have to do what we say" as it usually is with climate stuff.
I don’t think that a mass extinction event is what people usually mean when they talk about nature adapting to the increase in temperature.

As an EU citizen I need to apply for an ESTA to travel into US. They get my fingerprints and a photograph besides a scan of my password when applying to said ESTA.

The upper classes weren't riding Greyhound fifty or sixty years ago. College students would, yes. Some college students would book a $130 one-month pass and travel a lot. But in general, would you prefer to fly from one coast to another or spend three days on a bus? You have to remember that airfare was relatively more expensive then.

I never saw people standing in the aisles except once when the Midwest was fogged in and people were desperate to get home for Christmas. In those days I would stand in the back of the line, knowing that if the bus filled up, five or ten of us might get another bus all to ourselves.
> This section explains the leader election algorithm at a high level. It is by no means exhaustive and deliberately avoids any formal specification or proof. Readers looking for an exhaustive explanation should refer to the Raft paper, which acts as a strong inspiration for BlazingMQ’s leader election algorithm.

So their own homegrown leader election algorithm?

> BlazingMQ’s leader election and state machine replication differs from that of Raft in one way: in Rafts leader election, only the node having the most up-to-date log can become the leader. If a follower receives an election proposal from a node with stale view of the log, it will not support it. This ensures that the elected leader has up-to-date messages in the replicated stream, and simply needs to sync up any followers which are not up to date. A good thing about this choice is that messages always flow from leader to follower nodes.

> BlazingMQ’s elector implementation relaxes this requirement. Any node in the cluster can become a leader, irrespective of its position in the log. This adds additional complexity in that a new leader needs to synchronize its state with the followers and that a follower node may need to send messages to the new leader if the latter is not up to date. However, this deviation from Raft and the custom synchronization protocol comes in handy because it allows BlazingMQ to avoid flushing (fsync) every message to disk. Readers familiar with Apache Kafka internals will see similarities between the two systems here.

"a new leader needs to synchronize its state with the followers and that a follower node may need to send messages to the new leader if the latter is not up to date". I thought a hallmark of HA systems was fast failover? If I come to your house and knock on the door, but it takes you 10mins to get off the couch to open the door, it's perfectly acceptable for me to claim you were "unavailable". Pedants will argue the opposite.
$600 still seems really high to me as a European.

Busses here are more expensive than flying, however. Even if the bus ticket itself might be slightly cheaper than in the us. Hopefully costs keep going down, inflation adjusted.

> I don't understand how you can make queueing high-performance. Queueing things is literally the opposite of making things fast.

You likely need to read about message queues, why they are used, and why they have performance constraints. Message queues are a system, and the system to maintain those queues and content has an overhead. The project is building a solution that is higher performing than comparable systems.

Queuing things often makes things faster (!) as you are usually dealing with limited resources (ex: web and job workers) and need to operate on other systems (ex: payments) that have their own distinct capacity.

If you have 1000 web workers, and your upstream payment provider supports 10 payments per minute, you'll quickly have timeouts and other issues with 1000 web workers trying to process payments. Your site won't process anything else while waiting for the payment provider if all web workers are doing this task.

A queue will let you process 1000 web requests, and trickle 10 requests to your payment provider. At some point that queue will fill, but that's a separate issue.

Meanwhile, your 1000 web workers are free to process the next requests (ex: your homepage news feed).
Sure. $600k/month sounds like some fantastic pennies.

The second amendment does not apply to government officials acting in their course of duty.
Reading about Big Bang, I'm wondering about this: doesn't the fact that the Big Bang happened imply that there was some kind of state-change: from Big Bang is not happening to Big Bang is happening, and any kind of state-change requires the existence of time. Doesn't this imply that time existed before the Big Bang?
Yes but it is changing in very specific and problematic ways with well understood causes that are at least partly under our control. We do not understand it perfectly but we don’t need to.
Today I learned: while trawling is probably the word I should have used, I was unintentionally correct either way…
That can be 100% true, and humans can still be contributing to the current change? So not only would it be possible and desirable for us to stop contributing, but to try and influence the direction of change in a way that's more beneficial for more of us (which could be reforesting or olivine weathering or something crazy like solar shielding or sulfur dioxide cannons, depending on who you ask).

That's pretty fascinating. I suppose it could open the door to more interesting benchmarks like how fast one can push an old CPU on an old PCI-only motherboard.

If there is a causal relationship between those who sell drugs on the black market and deaths from those drugs, I don’t know if the means aren’t justified. Could I give my life to save 20, I’d consider that an honor.
Absolutely this. If you’ve built something profitable on someone else’s land, get big and cash out as fast as you can. It’s unsustainable, you’re just doing an arbitrage play while it lasts. Do well fast so you optimize for more dice rolls in the future.
Rented a MY a couple months ago and was surprised how much I, and more surprisingly, my wife, hated it. Now, I despise Elon and the risky safety decisions of Tesla engineers, so I'm biased, but I wanted to give them a shot.

Range was horrible. We drove about 100 miles and spent a couple hours over several sessions at superchargers. The handling and turning radius sucked. The controls were frighteningly distracting and confusing. Sound in the cabin seemed very weird, probably due to the glass roof and noise cancelling system. Finally, for a dual motor, I expected a lot more acceleration. I drove a Chevy Bolt for a year and was surprised how heavy and sluggish the MY felt.

The complaints of poor nations will be met with meager welfare packages and mostly tuned out by the working class of weather nations. It's how the world already operates.
This sounds like a fun project. Unfortunately, I don't have the bandwidth to tackle something like this right now. Perhaps if I every get sucked back into a tech lead role. It does make me think to look if there are any existing Git learning games.
One can do experiments to empirically test the earth is round.

There are no experiments one can do to empirically test things asserted before the Big Bang.
No, they were using more BTUs of energy just heating with gas and wood than heating and cooling with an electric heat pump. Also the carbon intensity per BTU is going to be lower on almost every European grid than directly burning any fuel.

This reminds me of a motorcycle forum I was on where some guy was outraged Canada wouldn't let him bring in his handgun while on his roadtrip, and while everyone tried to provide helpful suggestions of where he could safely secure it before crossing the border (and pick it up again on his return to the US), he instead was fixated on how obviously Canada didn't want his tourist dollars and didn't respect his freedom.
Building apps for other platforms, be they Shoppify or the App Store, always comes with the risk of getting booted off or Sherlocked.

You can pray that the platform's customers will be upset if your product gets killed ("Shoppify broke our checkout screen" is not exactly bringing in new users) but in the end you need an exit strategy as a company.

In this case, I do think legal action would've succeeded, but it would probably be a long, expensive, painful lawsuit, that's probably too much for this company to bear. You're also not guaranteed that the judge will make the losing party pay for your defence even if you do win, so it could easily be quite a Pyrrhic victory.

With the new DMA coming into effect soon, I think businesses like these will stand a much better chance. The restrictions put onto gatekeepers by the EU can introduce significant risks to platforms being scummy to smaller developers.
What's baffling is making energy more expensive and less reliable when all of human development has been about spending more energy per capita at less cost.

Those who take climate change seriously should have gone all in on nuclear, but somehow there was enough of an overlap between that group and anti-nuclear activists that it never happened. That's what's truly baffling.

More and cheaper energy is quite literally the solution to all of humanity's physical problems. I don't care if the summers get hotter or winters get colder, if we have abundant, cheap, stable, clean energy from nuclear sources. Barring that, abundant, cheap, stable, and regrettably unclean energy from fossil fuels is the second best option. But what some in the developed world has chosen is stasis, degrowth, and decay instead.

I may be ignorant, but you don't seem to be offering any viable alternatives to my ignorance.
The clock speeds are 100x higher so we don't need to match 1 for 1 with silicon transistors to have advantages.

You seem to be determined to interpret "all people should have access to information" through the lens of people trying to reach or indoctrinate others; if you continue to frame it that way I'll assume it's not in good faith. I am not suggesting that anyone has a "right" to get any particular message to any particular audience; nobody has the right to reach, or to a platform. I am suggesting that people have a right to seek out and learn from information even before they're 18.

> You just really don't like the idea that people will raise religious kids

I was using religion as a placeholder for any of a variety of common groups that try to restrict information.

> it sounds like you want your secular world views

Emphatically not. I don't want to see any particular worldviews pushed. I want kids to be able to read and learn. Whatever worldview they ended up with as a result of that, fine, at least they knew that other worldviews exist and what they say.

The path you're advocating is the path by which we get books being removed from libraries because someone complained about something in it. That path does not lead to better worlds.

And to be clear, I'm not advocating an all-or-nothing change here, just a different balance.

> You are justifying means because you like ends.

Yes, I am. From the most restrictive of environments, I have seen many hopeful stories of ingenuity in passing information by word of mouth about how and where to get less restricted access to information. I'm under no illusions that such channels are exclusively used for positive things, and I hope you're under no illusions that such restrictions are exclusively used to "protect".

I don't particularly expect to convince you. You are free to advocate the contrary. I draw hope from the fact that it's nearly impossible to completely restrict access to information, and I wish people the very worst of luck in trying.
This last peak was the Eemiam period, a brief-ish inter-glacial peak the end of the glacial Pleistocene period: an overall much much cooler era.

As a personal VM machine, vbox is fine. But for anything more involved, it's got a lot of rough edges.

We used to use virtualbox at work to run our CI workload (spawning a fresh VM for every job). Long story short: It does not scale well at all. Its scripting API is terrible, we ran into endless network problems (for instance, its builtin dhcp server would sometimes fail to flush expired IPs, leading to running out of IPs to give), and it would sometimes just freeze up entirely, requiring us to restart the virtualbox services.

We switched over to kubevirt[0] (essentially qemu/kvm inside a kube cluster) to handle our CI, and it's been a much, much smoother sailing since then. And it even allowed us to run macos VMs on linux hosts, something that we never managed to get working in vbox.

> Does QEMU have this for MS Windows and Linux *6 guest OSes?

QEmu has virgl[1] for paravirtualized graphics, but its windows drivers are unsigned afaict, so you can't really use it there. Works fine on linux, so long as your mesa and kernel aren't super ancient.

> This doesn't require a separate medical system, it requires prompt intervention/treatment at the beginning of the illness, not after many many visits.

I fully agree. The same goes for cancer, dental health and countless other diseases and ailments. The solution is having a stronger social safety net - but America appears not to want that, so here we are.
