Trains can be, and sometimes are, evacuated in a tunnel. The front (and rear, these trains are symmetrical) can be opened, converting into steps for able-bodied passengers to walk down to the tunnel floor.

This is how I see it too.

Baby Boomers and Gen X had quite a different view of psychological issues and it had a detrimental effect on population at large. Now that a lot of the taboos surrounding it are broken, later generations are emphasising them by exaggeration.

I don't see it as an issue at all. I see it as the pendulum swinging back with more force than it was pushed.
It's ludicrous to think Biden would green light an operation like this when he finally has a European coalition against Russian aggression helping Ukraine whin the war.

This would destroy that coalition in seconds.
The carnage happened at 9.30 am on Friday directly after the budget announcement, caused by the budget announcement. Energy subsidy was proposed earlier in the week. The market suddenly realised that kwasi and liz are irresponsible idealists and acted accordingly.
This is in large part what drove me out of programming to become a patent attorney. I started out as a moderately competent enterprise java backend developer who really knew his way around the major app servers.

Then things changed around me quickly, and one day I woke up and realized that I had hardly any idea what was going on any more. Cloud ops, docker, kubernetes, etc. It was exhausting trying to keep up and it made me lose interest in getting better.

I always knew I wasn't going to be a programmer forever, but modern devops stuff accelerated the transition out.
True story. I live near Princeton (NJ). Approx 5+ yrs ago I was out one evening in P'ton for drinks. Bumped into an acquaintance. She was sharing a table with a guy. I stopped to chat.

Long to short he was David Gates from PPPL. Two things I remember:

1) He was down to earth and was glad to field my novice questions about fusion. (I didn't know exactly who he was til I looked him up the next day).

2) When I asked if fusion was going to happen, he said yes and that it was a matter of getting more money to back the research.

It's simply a matter of time.

Emacs is his baby in a way.
It is his privilege to develop it in a way that he believes is best.

Much like how Linus has a decent say in what happens to Linux.

Why should RMS change how he does something because some big corporation can write a propriety editor, and a proprietary compiler?
This is nothing new. There were plenty of proprietary compilers at the time the project started and that was one of the primary reasons to write it.

Instead of bitching about leadership on a free software project and feeling entitled to have it changed to yours and others liking
If you feel strongly that Emcas or GCC is heading down the wrong path,
you are 100% free to fork it and within the limits of the license write
whatever features you want,

Perhaps if it is hugely successful or the features do turn out to be
killer additions GNU may decide to add some to Emacs.

In so far as fighting the good fight for Libre software it is the same fight he has fought for decades and the way the world has developed lately I would say most of these predictions have come true.

RMS is extremely smart and extremely dedicated, and he has made a lot of sacrifices due to his principles.
Yes, he is stubborn (So is Linus) and eccentric.
So what?

How the F can people claim to be fighting for an "inclusive society"
if you can't let a guy, be a bit eccentric.
If anything, we need more eccentric people in a society that is turning ever more and more homogenic.

And please consider that Linux would not exist today if it was not

Today they can be replaced but back then it was available for free.

From a brief review of Peter Kramer's Against Depression (2005):

Consumption (tuberculosis) was viewed as a somewhat fashionable disease, a sign of an artistic and intellectual nature. (It was probably viewed that way by artists who contracted it; the greater "unwashed masses" who also were afflicted with the disease had no such pretensions.) Of course, tuberculosis eventually succumbed to medicine and fell out of fashion. (It is still a problem in communities underserved with health care.) To a certain extent, depression has some of that cachet attributed to consumption by earlier generations, but Dr. Kramer thinks that depression will eventually go the way of tuberculosis and be cured with medicine.

I've suffered from severe, treatment-resistant, unipolar depression for over 25 years. I respect those who are able to pull themselves up by their bootstraps and don't let depression define their lives, but there are a lot of us who are not that strong, for whatever reason, and for whom depression majorly colors our lives.

In the past write monolith,
debug one application and one database. Attach debugger to monolith. Cache in ram/l3 cache. Deployment copy monolith binary in placce, run it.

Now, write distributed micro service. Many many programs. Many databases and queues. How do I debug that? How do I monitor that. We get scalability minus L3 cache access. Now deployment orchestration. Win zero down time deployment.
It seems to me that most people just want everything to be rational. It's just that the most idealogical on both sides are the ones that are always speaking.
Although in this case there's no evidence that it was a useful invention.
Many many engineering problems are basically “build a copy of that thing over there, but build it here”. Software is often vastly different each time.
This seems to be the largest potential issue then with my understanding of requiring research a-priori to match an assumed outcome or ideal. I wonder if an academic wanted to rigorously attempt to isolate between these, would they be allowed to publish the results were found that systemic issues were not significant. It seems potentially dangerous if we stifle publications of studies that find minimal impact of racism because it could have the impact of only highlighting the cases of racism, but not the net impact.
The US ultra-rich justify their low tax rates with three myths
i cannot use a facebook page as anything posted on pages requires boosting which is completely unaffordable for smaller business. in the end your content is shown to some guys in vietnam and if you try to narrow the audience facebook expands it such that the acquisition cost of a real customer becomes insanely expensive. facebook ads never worked and are a big scam.

so i need to use my personal profile to build relationships and sell. this means i get pulled into personal use of facebook which destroys my mental health.
That is one specific definition of a recession.

It's funny to me because if we're resorting to semantics and nitpicking to prove whether or not there is a massive and broadly defined societal issue going on, then it probably isn't really happening... at least not enough to write home about.
Biden and Nuland threatened to stop it using their political leverage, not force.

Sabotage would destroy the European coalition against Russian aggression they've worked so hard to build.

Indeed, the Web Content Accessibility Guidelines explicitly allow creating a separate accessible version of content and linking to it. They call it a "conforming alternate version": https://www.w3.org/TR/2016/NOTE-WCAG20-TECHS-20161007/G190

(The guidelines say it's preferred for everything to conform directly, but they use "artistic integrity" as an example of a situation where a conforming alternate version could be used. I'd say that applies here.)
Is there a reason why modern planes can't shoot backwards? A lot of the WW2 planes had turrets a separate gunner would control, but they all seem to have disappeared.

My only guess is that dogfights don't actually happen much anymore.
Let me try again. You receive three resumes for a job application, for three humans of three different races. They have the exact same credentials. You immediately assume one of the three is the brightest of them, because your understanding of Affirmative Action Policies says this particular race has the highest likelihood of having higher overall test scores.

One of the other two could have had the highest possible score of all time, but you have written them off by making an assumption about them, based on race. You have made a judgement based on statistical inference, when you should have treated them all equally.

You may not intend it in any ill-meaning way, but it is important to realize that minor assumptions like this are pervasive, and they have far-reaching effects.
They're sorted by last name, it took me a second too! I just wish I knew more of them.
Ok, so you find an artist that you like and (perhaps together with some other fans) pay them a salary.

No need for artificial constructs like copyright law.
I really like Racket and write as much as I can in Typed Racket. It's great but also has lots of weird little warts that I keep stumbling across. One of the biggest for me is that type signatures completely take the place of untyped Racket's contracts. It's way too difficult to have both types and contracts attached to things. Ideally one could write a contract for things that are not able to be expressed in the type system but Typed Racket doesn't let you.
Bullets don't move at the speed of light.[1] Shoot a bullet backwards off a bullet train, that bullet's ground speed is less than if shot from the ground while stationary. Similarly, shoot a bullet forward off a bullet train, that bullet's ground speed is more than if shot from the ground from a stationary position. Shoot bullets backwards off a jet moving Mach 3 (just sayin') those 1700mph bullets will still be moving in the forward direction of the jet at 600mph relative to the ground.

> But the worse part for me is the accumulation of abstraction layers and dependencies.

Yes, open source has a lot of positives, but the bad part is how it has created a culture that incentivizes such a huge amount of dependencies for every project. It seems that for any new requirement the only possible solution is to add a new dependency on yet another library. This results in fragile builds and daily changes caused by dependency updates. In some cases it causes as much troubles as the perceived benefits.
It incentivises using the cheapest energy which is renewable. Bitcoin could even be greenhouse negative - just stick a mine on top of every landfill around and you have a recipe to get rid of methane gas. Or on oil fields where they accidentally run into gas pockets.

Looks to me like GHG emissions are going down this year, from that report. I would expect that to continue going forward as more miners are deployed on top of cheap electricity sources :)
Like I said, it's very formal.

One common situation is introducing an invited speaker at a conference. After the first mention, you refer to the speaker using a mix of pronouns and names. Full name or last name would sound weird. Using first name works if the speaker is your friend and many people in the audience also know them as a person. Otherwise "Dr. Lastname" is a reasonable choice.

Academic websites are full of short biographies of speakers, lecturers, PIs, and so on. They are often written in third person. Again, "Dr. Lastname" is often the form of reference that sounds least weird.

Academic spam is often addressed to "Dr. Lastname", especially if the sender is asking the recipient to do something. Using "doctor" as a title is a safe default choice. It sounds respectful, it's very likely to be correct, and it saves the sender from guessing the gender (and possibly marital status) of the recipient.
No opinion here, but I think the idea is bitcoin seeks _cheap_ energy which encourages miners to use mass sources of solar/wind energy that are plentiful but in undesirable places like Arizona. Hence, one can conclude that miners are pro-renewables and will invest in their research. \_(ツ)_/¯
Naturally, societal convenience / cost savings / chosen compromises are part of the structural discrimination that occur, similar how those effects influence discrimination in other areas of society. As an example, profiling by the police is a fairly common cost savings tactic, but we have rule in place to prevent the police from using it. If it wasn't convenient, cultural, or saved money, then most problems of discrimination would not exist in the first place. It is a bit however about how we frame it. If cost saving efforts create discrimination, then we call the system as being designed in a discriminating way. Call it a naming convention in social science.

In general I agree with all those things you say that we should provide to children. Most of that is what my own country laws says that school should provide, and to add, it should be adapted based on the individual child needs and ability. I would add to it what the article just briefly mention, which is that matching gender between teacher and student has a fairly long history of showing improved results. There is still need to do more research on the subject, but there has been studies done since the 70s that shown how gender of those around a person can influence behavior. I have even remember reading in one study that the conclusion should be uncontroversial by now.
Is Linux a popular option for real-time? Or are other OS more relevant in this field?
> The idea is, to be able to make the kill, after you are now behind. Then it does not matter, if you are too slow.

Air combat is rarely 1vs1 so being slow means you get killed by someone else.
> based on anti-racism principles these policies are indeed anti-racist, and discriminatory against whites.

I don’t think the best policies are racist. Providing more financial support for single parent households helps poor, struggling single parents of every race. It doesn’t discriminate.

And nor should it - poor white children deserve support just as much as poor black children do. No child deserves to be homeless.
Which indicates that something is wrong with the residential electricity markets. Google should not be paying substantially less for marginal electricity than Google’s customers.

(This is a major problem with California’s energy planning. On the one hand, CA (IMO fairly sensibly) wants users to switch from gas to electricity. On the other hand, CA’s electricity prices are so egregiously inflated that people have an economic incentive to switch from electricity to gas.)
Fortunately the companies that understand gaming have similar-but-better solutions that are still perfectly viable. Assassins Creed games on xcloud have been a delight.
Your opinion is far more unqualified than a carefully researched blog.

If you don't think what he wrote is true, rebut him factually, random HN guy.
How many "professional" programmers even know the difference between BRE, ERE and PCRE.

Perhaps this is why use of regex is so controversial amongst a majority of "professional" programmers. They are trying to use PCRE for every pattern matching task, i.e, even ones where it is not necessary, whether it is within their programing language or with command-line utilities. This "Bash one-liner" is a simple example.

I have reviewed a number of books written about regular expressions and for the most part^1 they focus only on regex as implemented in popular programming languages. That almost invariably is PCRE or some form of PCRE-like pattern matching. There is little distinction, let alone acknowledgment, between PCRE/PCRE-like patterns and anything simpler.

Not being a "professional" programmer, I use regex everyday but I never (intentionally) use PCRE.^2 Too complicated for my tastes, not to mention slow if using backtracking.

1. I recall one older book that did include an incomplete table attempting to show which type of regex was used by various UNIX utilities in addition to what regex was used by popular programming languages of the day.

2. For programs that optionally link to a PCRE library, I re-compile without them without it.
Thank you! I have been trying to get some attention to this project. The submission last week was a Show HN for the Common Lisp source code which was open sourced only very recently. Thanks to the wonderful HN community, that post did get the attention I had hoped for.

I made another submission this week to show the live MathB.in website in action. That did not get any attention. Since the HN FAQ allows a small number of reposts if a post has not had significant attention in the last year, I thought of reposting the live website link once again today.
"It" doesn't understand anything.

It's just a very advanced madlibs engine based on a database of a billion of already known images.
I'm genuinely missing your point. It sou d like you're insinuating that the lack of a "normal" name is a good reason to disqualify someone from a job opportunity. That possibly implies that the resume screen uses someone's name as a discriminating factor and I don't think that it should be.
Perhaps parent meant MIPS.
I'm not aware of one. Is there some WASM drama going on lately?
But can the secondary be set off without a tertiary?
Yes, rethinking UI for eye tracking is what Eyefluence was working on. And in fact we showed Apple all of our stuff before the acquisition. I believe we were in acquisition talks with them as well as Google. I spent a lot of time on the Apple campus tweaking our neural nets to their liking. This was prior to their publishing of that eye tracking work.
Thank you! I am glad you like it!
The Arabic script is harder to print using movable types compared to the latin script. It's an important reason for the lack of adoption of the printing press in languages using the Arabic script (historically speaking of course).

It can apparently trigger them in susceptible people. I got to see it first hand.
FWIW, I actually mostly agree with Linus.

I was paraphrasing. I didn't want to write a page length comment, and won't here, but there were a few more instances of similar ultimatums (like "Or, you know, if you can't deal with the rules that the kernel requires, then just don't do kernel programming.") And all are similarly ridiculous/dickish. Really no need for such dramatic convulsions, Linus, where Wedson was simply trying to explain the API expectations of the Rust language.

Re: the rest, I think you are conflating Rust's UB guarantees with a specified memory model.
For what it's worth, most countries, including the US, are parties to the Convention on Certain Conventional Weapons, of which Protocol II requires a ban on "the use of non-self-destructing and non-self-deactivating mines outside fenced, monitored and marked areas"[0].

I think that means that countries have to either use mines which decay over time, as you suggest, or they have to remove the mines themselves from any designated area once the relevant conflict ends. I'm not sure if any signatories have deployed any non-decaying mines since the convention entered into force, though.

However, if I may use the old allegory, in the deep darkness of this dei temple, there is light of the inner life. While the priests of the temple further their goals, power over others in particular, they, in fact, unknowingly implement the will above them, that's pushing our society away from individualism and towards some basic form of unity. Individualism has been necessary to develop intelligence, and now that we have it sufficiently developed, it's time to move on to the next milestone - a form of distributed mind. Once the transition is over, the priests of ignorance that thought themselves powerful will be overrun by the crowd.
So we could let them keep their stocks and not trade them for dollars; they own 100% of their company and the public is no longer obliged to acknowledge outsiders have ephemeral value beyond their direct contribution to society.

Demanding we believe in ephemeral property is spoken tradition not an immutable truth of reality. I am not saying we have to redistribute their wealth; I’m saying we stop idolizing wealth. Especially when tax policy and direct cash infusions from government is keeping these guys afloat. It’s not free market trade. Look at their tune change as soon as free money is shut off with interest rate changes; it’s not them it’s political policy. They’re not actually rich.
That's a lot of work for I don't know how much gain. And, more importantly, I have to agree with a number of posters here that page (and anything like it) is an accessibility nightmare.
I don't think so. The way I'm reading it, both fighters should be in a turn fight with the opponent closely following Boyd's rear at high speed.

In the case of a flat plane, you're dumping airspeed but you don't stall the aircraft. This guy explains it way better then I can, describing the maneuver as a Rudder Reversal: https://www.youtube.com/watch?v=5ab6Ek1UCcM. Skip to 2:07 to see him demonstrate it with model airplanes.

The Cobra you do enter into a stall (the airflow departs the top surface of the wings) and are instead relying on other some other aspect of the plane to control the aircraft and get the plane back into the fight.

Note that this is just what I know from superficial memory, I never studied it in depth.
Persian is written using a variant of the Arabic script, as is Urdu.
It requires not just any Nvidia GPU but "NVIDIA GeForce RTX 2060, Quadro RTX 3000, TITAN RTX or higher"...
I don't think that's true though. It's not very bandwidth demanding to stream 4k 60fps or 1440p 120fps, GeForce Now does that already out of the box for less than 100 Mbps.

But it's hard to sustain those frame rates at max graphics. Ue5 will raise the ceiling quite a bit too. The gfx cards will continue to be a bottleneck for AAA games.
Frida Kahlo comes to mind.
To put a gun in a turret it's got to be pretty small. Turret guns were therefore only good for shooting at slow, close aircraft. You basically don't get that anymore.
