In Spain, public transportation already suffers from many problems. And this can only make it worse, because guess what? The government isn't spending a single cent in improving our network, it's only going to allow people to board for free. And I don't think anybody already using his car will now use the train, because despite being "free" now, it's not going to be better than using your own car. But you're right, I don't think anybody using the train will switch to the car again, because fortunately, this will only last until December. And it won't start until September, because the government didn't want the tourists to benefit from this measure.

That's quite the odd statement, as all it takes is a 5min tutorial to get up and running on 95% you ever need to do with git on a weekly basis, and 100% of what you do at an everyday basis.

This is not the brag you think it is. If you need to know 50 commands to do daily work with a revision control service, that service is appallingly broken by design.

If we consider baseball or football prowess instead of soccer:

The Dominican Republic is vastly over-represented in the population of pro baseball players. I think you could easily find countries in Latin America to use as a control (same income level, same population, etc.)

The answer is most likely not diet, but the first-mover effect: a lot of Dominicans became baseball players, so American teams started scouting them more, pouring more into player development, etc. Young kids started seeing it as a way out of poverty.

I think American Samoa is also over-represented in the population of NFL players.
Totally agree with “just”.

Just to clarify, I use a $5/mo DigitalOcean droplet plus an extra dollar or two for backup and then a rsync.net account (that I use for other backup purposes too). Off the top of my head, that is the extent of my expenses for this set up (it's possible I might be forgetting/missing something).

And you are correct, that I work through the Chromebook but when the other monthly expenses don't exceed the cost of lunch, I don't think there is too much missing subtext.
> Even if he had, he's comparing Twitter AI-flagged revenge porn posts against user-reported harassment posts. The former is pretty clear cut and Twitter flagged it themselves. The latter may be a judgment call and was probably reported by the alleged target.

I would consider humans manually reporting tweets to be much more reliable than AI flagging, especially given the bizarre false positive results we've seen from Twitter AI flagging.

I've personally reported tweets, with the same kind of non-results. Mostly bots though rather than harassment.

The false assumption here is that there is a “broader national project.”

The United States was never an Enlightenment experiment like modern France. It wasn’t about unifying a people through rationalism and science. After all, Massachusetts Puritans were one of the country’s key founding groups. More than one state had an established state church at the time of the American revolution.

The United States was from its inception a very different project: a pluralistic society where different religious factions—Puritans in Massachusetts and Episcopalians in Maryland—could live alongside each other without going to war.

Our “current events” illustrates the folly of subsequent attempts to make America—a place that has myriad distinct cultures even amongst supposedly “white” people—into a French-style unitary secular republic.

Your comment about “retrograde” outcomes is pretty odd. America is by far the most religious country in the developed world—Americans pray daily at the same rate as people in Bangladesh (a place where daily prayer is a central aspect of the religion!) America is also the most successful country in the history of the world.
That’s refreshing to hear. Good on you!

I mean isn't it obvious that we are missing opportunities here? Are we really that complacent that we can't achieve anything on a grand scale anymore?

> Chiefly, continued energy growth will likely be unnecessary if the human population stabilizes.

I doubt our insatiable hunger for more, more, and more will stop anytime soon - even if the numbers stagnate, our egos will grow bigger and bigger and we'll want more and more. It's in our nature. So why not go beyond our planet for that never-ending "want"? Consumer everything that's out there and turn into shiny new crap for down here. Once we are done, eject it into the sun and keep the earth tidy.

So my initial reaction to this was "who gives a sh*t"? Once you are in the real world of work you will be socializing with people much older than yourself and several years into your career you will be socializing with people who are much younger than yourself. Look more at mindset than age, besides 2 years difference is absolutely NOTHING lol.

A point that I haven't seen addressed in other comments is the cost. If the additional 2 years ends up costing you a lot more money then I would vote against it. If you are in a country where tuition/boarding are paid then that isn't a factor to consider.
Flying is artificially cheap to the point the ticket prices make no sense. It's massively subsidized, so it's not really fair to compare it with the train.

Anyways, I have to hard disagree on flying being faster and easier than going by train. Flying is a pretty horrendous experience in comparison, and if you account for the time spent in the airport and getting to it it's not faster either.

> In France such lunacy is unthinkable because they have freedom from religion

So by banning modest clothing and mandating mixed sex bathing, French women are "free" from having to see or accept the existence of Muslim women, whereas Muslim women are "free" to abandon their beliefs about modesty or not enjoy the bathhouses their taxes paid for.

That reminds me of a quote by Anatole France, who happens to have been French, and who wrote: “The law, in its majestic equality, forbids rich and poor alike to sleep under bridges, to beg in the streets, and to steal their bread.”

While GNU tar inherits this from the original tar, it doesn't seem to be something intrinsic to the PDP-11 or DEC given that the earlier Unix 'tap' archival system uses 'plain binary numbers ("base 256")', not octals.

Here's the V7 tar.c: https://github.com/dspinellis/unix-history-repo/blob/Researc...

and it's documentation: https://github.com/dspinellis/unix-history-repo/blob/Researc...

The C code clearly shows the octal (I've never used "%o" myself!):

sscanf(dblock.dbuf.mode, "%o", &i);
sp->st_mode = i;
sscanf(dblock.dbuf.uid, "%o", &i);
sp->st_uid = i;
sscanf(dblock.dbuf.gid, "%o", &i);
sp->st_gid = i;
sscanf(dblock.dbuf.size, "%lo", &sp->st_size);
sscanf(dblock.dbuf.mtime, "%lo", &sp->st_mtime);
sscanf(dblock.dbuf.chksum, "%o", &chksum);

Now, older versions of Unix supported DECTape, going back to the first manual from 1971 (see the "tap" command at http://www.bitsavers.org/pdf/bellLabs/unix/UNIX_ProgrammersM... , page "5_06", which is 94 of 211 - the command-line interface is clearly related to tar).

Here's the tp.5 format description from V6 at https://github.com/dspinellis/unix-history-repo/blob/Researc...

DEC/mag tape formats
...
Each entry has the following format:
path name 32 bytes
mode 2 bytes
uid 1 byte
gid 1 byte
unused 1 byte
size 3 bytes
time modified 4 bytes
tape address 2 bytes
unused 16 bytes
check sum 2 bytes

These are in essentially the same order as the "struct file_header" for tar shown in the linked-to essay.

But you can see at https://github.com/dspinellis/unix-history-repo/blob/Researc... that mtime is an int[2], so 4 bytes (yes, 16-bit integers; confirm with https://github.com/dspinellis/unix-history-repo/blob/Researc... showing i_mode is an integer).

Which means this older "tap" DECTape support uses 'plain binary numbers ("base 256")', not octal.

There are really two questions here: (1) Is 20 too late to start college? (2) Should you switch to a (possibly) better school even if no credits transfer (so you have to start from scratch)? I think there are too many unknowns to answer (2) (and I never saw anyone move from one school to another and not be able to transfer any credits), so I won't say anything about that part.

As far as (1) goes, I had around 5000 students in my career (give or take). Some were starting college in their 20s (e.g. after working right out of high school, or having served in the military). But I had students starting school in their 30s, 40s, 50s (!), though the oldest tended to be people who were returning for a second degree (very often they wanted to teach, which is just wonderful). The majority completed their degrees. They seemed to get along with their younger peers pretty well, though that depends on personality. (I'm thinking of a couple of guys in their 50s who'd sit in the tutoring room happily studying with students who were young enough to be their grandkids.) It helps to not be too self-conscious ("I'm so much older than my classmates"), and to think of the people around you in terms of commonalities rather than differences (e.g. you're all students).

People who had been away from school for a while would probably have a bit of rust, but it was more than made up for by "life experience" - for instance, knowing what you want, understanding that you need to work at things (and being able to do it), having the ability to self-monitor (which seems to develop on average in the late teens to early 20s).

I'm not sure how much of the above is relevant to OP's situation, but I hope it helps.
And fusion will never be able to stop emitting massive amounts of waste heat that must be dealt with somehow.

I'm not sure what benefit density provides, especially since people obsessed with density seem to only focus on the reaction chamber, which is the smallest part of the massive building and heat rejection apparatus that will be needed.

Rejecting waste heat is a real difficulty, and part of the reason that's France's fission fleet is at less than 50% capacity right now.

Thermal electricity production has a chance of becoming obsolete compared to direct conversion of photons into electricity. When solar plus storage costs less than steam turbines plus heat rejection, then it doesn't matter how cheap or dense the fusion part is in terms of economics.

It wasn't intended as a jab at all, but I can see how it came across that way. No offense intended, and I do apologize for that. Still, the end-user desktop UX for MacOS and Windows is a major piece of why people use those over Linux as a desktop computing environment. (Nothing wrong with Linux itself mind you, more the ongoing fragmentation, but that's another topic entirely...)

Another important aspect to look at sometime would by typography. In traditional print medium we always used to hear that serif fonts (the ones with the itty bitty hooks on the ends of letters - e.g. Times New Roman) were useful because it helped the eye move along the line. But on computing devices, used to be that the best practice was sans serif fonts (e.g. Helvetica, Arial) because of something to do with the way the fonts get rendered on a screen. That was long before the availability of 4k monitors though, but supposedly it reduces eyestrain and helps with clarity.

I never looked too much into that, and just went with what all the design specialists out there recommended (again, I'm a crap designer). But from this little example we can see that even the shape of the letters themselves plays a role in communicating a variety of things.

Imagine all caps, serif-font, white background, dark blue lettering:

= S M I T H =
FOR OFFICE

Comes across as authoritarian, right?

Now imagine the same in sans-serif, black on white, and maybe "for office" laid out beneath the name on the next line, spaced and sized so that the width of each line is identical:

= S m i t h =
For Office

Comes across as more formal and respectful but less fear inducing, doesn't it? (HN doesn't let me design here so you'll have to use your imagination of course! ;-)

Anyway, this is just a simplified example of how typography not only conveys the words themselves, but an emotional sense along with those words. There's subtext within subtext possible here, and this entire field is dedicated to communicating more than data, and doing so at a very high rate of efficiency - including the things that don't get communicated well through words.
>the biggest problem public transport faces is quality and not cost

There is an interesting, very American, solution, which is ubiquitous, active surveillance on every form of public transport. Not just for violent threats, but for enforcing (current) vandalism, littering, and even assault laws cheaply and at scale. For the low low cost of a dystopian panopticon you could have, theoretically, a cheaply maintained public transportation system. (The other option, which many other countries employ, is a rigorous culture of respect for public places and public facilities -- for example Japan and Northern Europe.)
You've seen it now, and I asked you to "consider" something as well.
Ask HN: A matching site for intellectual/study partners?
Here's an idea for a site/service that I would love to use. This must have been tried before, but I can't find a lot of examples:

A matching/partnering service for intellectuals, or people with those interests. For example, let's say I want to read a big/hard/long book, on any topic, with someone else. I could create a pitch for some reading project or course of study: create a post where I discuss what I want to get out of it, disclose any prior knowledge or training, etc..--then let anyone who's interested propose to read/study/research with me.

I know book clubs are a thing. I found https://bookworm.club, a reader matching service posted here[1] less than a year ago, but what I am thinking about is a little different. It would be broader matchmaking service than just book reading, applicable to any project involving committed study or research. Maybe I'm good at math, and I'm looking for someone who's interested in doing a self-guided intro to quantum mechanics. Or I'm interested in learning more about early US colonial history, and I want someone to help me pick the five most important books on King Philip's War to skim and synthesize. Or I have an idea for a robotics hobby project, and I want to find someone with a technical background that's complementary to my own. Or I've always gotten stuck on the fourth book of Proust's In Search of Lost Time, and I want to find someone to go through it with me and discuss every two weeks. Anything--you define the terms.

I know formal classes and education are an approximate solution here, but I think that a person's commitment and interest are often higher in cases of self-study, because your motivation comes from being clear with yourself about what you want to get out of your efforts. Self-studiers are a special group. There are also a lot more niche interests than formal classes.

My guess is there are actually a good number of smart people who want to do these things, but they give up because the chance of finding a suitable partner is low. The people with the same interests are often irregularly distributed. and feel isolated. A service that would work at internet scale, especially with more people willing to do this over Zoom, would help to match a lot of these ardent intellectual loners on the long tail of interests.

My initial sense is that a good match between prospective partners would be hard to discern algorithmically, since so much about intellectual fit depends on the nuances of what they want to do. So the actual matching would involve pitching, conversation back and forth, negotiation, etc.

Anyways, can someone point me to previous efforts in this area? General thoughts are of course welcome too.
