There was quite interesting pilot service run by the entity responsible for the public transportation in the Helsinki region in 2012-2015. It was called "Kutsu Plus". There is a report available in English [1].

This service was something between bus and taxi. They were operating small busses. All the rides started and ended at a bus stop (which you have plenty in the region). You would use a website/mobile app to tell where you are going and when. The system would then optimize the requests from multiple people, determine the routes and tell you when to be at the bus stop, how long the journey takes and the price.

Eventually the service was shut down as the local municipalities did not want to put in more money to support it. All the trips were very heavily subsidized. They would have needed to significantly grow the pilot to see if could have become economically feasible.

Seems to be the software side of the project is now part of Volkswagen owned Moia [2].

For most use cases pointing devices makes you less productive than using a keyboard. Going forth and back between keyboard and a pointing device is even worse.

If you watch PBS Spacetime on the 'Kugelblitz' idea, it seems that one way to go about it (over the course of a couple hundred years) would be to convert Mercury into a solar energy collecting swarm by use of Von Neumann probes and essentially harvest much of what the sun has to give. That kind of energy apparently would suffice to create tiny black holes (simply by redirecting enough energy to a focused point), which is I think the theoretically most efficient battery (or star system destroying bomb, depending on how you go about it...).
I don‘t know why nobody is mentioning it, but Esrange[1] in Kiruna is an active European launch site, arguably far more North than Sutherland. Even though launcher activities seem to be limited to sounding/sub-orbital rockets at the moment, I don‘t see a reason why they should be restricted to it.

There are stores selling knock-off easy to manufacture parts like body, some basic electronic components etc, and yes, as I said, the logic board itself needs to be original.
You are mistaken about what you use and what you don't.

You only really consider what you personally, directly use, but seem to be ignoring all of your indirect use.

Those other miles of highway are used by the transportation to deliver goods to your town. That benefits you. Those airports are also used in such a manner.

There's also the twice removed use. In order for your community to function, you need a certain population density. Providing service to just you is cost prohibitive for any utility. The last mile is a bitch when it's really the last 100 miles. So, all of those other people in the nearby towns also need to be able to subsist in the area. In order to provide you with service, in order to make it cost effective to run shops, etc.

The way I've begun to see it, the government is like a buffet or club and taxes are what we pay for access.

Sure, you may not like crab legs, but some portion of what you paid is going to those crab legs. Or maybe you use the pool at the club every day, but Joe can't swim so he never uses it. But the same percentage of your dues go to paying for it. It all comes down to the fact that in order to make the things you want accessible and affordable, you will have to kind of pay for things you don't want.

Taxes are the dues you pay to be in the club that is the U.S.A. (or whatever country you're in, but it rhymes with U.S.A.).
Interestingly, I grew up thinking the exact opposite. In the Torah Methuselah is mentioned as having lived 900+ years.
That's to be expected. We're amazed by the realism of the pictures of pre-photography times, although nowadays anyone can achieve even better results with some simple copy methods and a photo.

Kind of sad to see in every art subreddit just "human-photocopied" pictures being upvoted (extra points if you digitally color-picked all shades of color from the photography, besides the usual tracing of every line) instead of real, creative art...
Instead of addition, why not use an actual hashing algorithm, truncated to a certain number of bits? That'll give you better binning and give you flexibility about filesize / number of file tradeoffs.

I like the idea of using unicode characters -- have you performance tested it to see if it gives superior performance to an ASCII filename of the same number of bytes?

Bespoke Software: Advantages and Disadvantages for Business
Pardon the interruption.
I'm another special case. The only good thing of the mac touchpad is pinch to zoom integrated into many applications. I really don't want gestures. Scrolling and moving the pointer on my HP laptops always worked really well. Maybe it's a HP thing. However I remeber that the same touchpad worked much better with Ubuntu 8.04 than with Windows XP. Two finger scrolling instead of scrolling along the edge, among the other things.

I disable clicking on the touchpad and I use the 3 hardware buttons because they're much better at being buttons and how would I middle click and paste with a touchpad? Plus maybe the cursor nudge from the article. No, the touchpad won't sell me a Mac.
I wish they‘d use real, dying or dead languages instead of inventing advanced gibberish for movies. We could preserve languages for posteriority and the result would be more realistic.

Ask HN: How do I push myself to switch a company
This will be a long one so bear with me and read along. I have been at my current company for around 3.5 years. Its been a good experience. But I feel i am not challenging myself enough after 6 years as a dev. To be honest challenges and tech is not the only thing that drives me to believe this. As is the case salary is indeed a dominant variable in the whole equation. I am passionate about the craft i.e dev so the kind of work always is a priority over the money. But with age , after around three decades one does want to achieve a certain financial stability. Coming to the pushing myself part. I know I have the capability to get through tech interviews, but still lack the level required by companies like MIcrosoft , Amazon etc. I do want to apply to these companies but , a part of me is intimidated when I go through interview experiences at these companies. After years I do know how dabble with tech stacks , deliver production grade software and get stuff done. But lack discipline to follow a schedule nail the concepts to get through the big companies. What so you think? Any experiences or pearls of wisdom to guide a fellow dev on a long road to nowhere and help find a direction?

> Who is William Proxmire anyway?

He has an interesting wikipedia page. I can't for the life of me figure out why his campaign paid Krugman for this paper. Perhaps he gave the campaign (and it's anti-space-exploration platform) something they weren't expecting, and they had paid in advance. :-) More likely it was Krugman making a joke. There are several others in the paper.

Krugman's paper is interesting in arguing whose clock should be used for the calculation of compound interest and makes the perfectly reasonable argument that if a common frame of reference between the planet-bound sender and receiver is avaialble, that should be used, otherwise the receiver's (and certainly not a relativistically moving transport vessel). There's really not that much physics in it, which he cheerfully admits.

He also argues that the interest rates of the trading parties would equalize with trade. Again, perfectly plausible (and, it turns out, in the intervening decades that has essentially happened on Earth). He does have a relativistic take on this, though, doing roughly a Lorentz transform on interest rates. Maybe it partially anticipated the investment into low-latency/high-frequency trading that has been popular recently?

Again, relying purely on GPS and inertial sensors is foolhardy.

What’s the catch? If powertop is so good why isnt’t it built into distros?
Whoa, why? Or, more specifically, why are you not using migration from a prior Mac or from a Time Machine backup? The ease with which a Mac user can be up and running on new hardware is, to me, one of the larger advantages of the platform. I know, this being HN, that you likely have a number of FOSS tools installed; are they somehow not getting picked up properly by migration & backup?

True story: we were robbed in 2012, in a quickie smash-and-grab through a rear patio (glass) door. They were in and out in maybe 1 minute, and took only what they could see from the yard -- which included my Macbook Pro.

We're well insured, so I went and got a new one the next day, plugged it into my Time Machine drive, and went and had lunch. When I came back, my new machine was ready to go -- all my apps, all my data, and even all my app windows were restored.
The fact that the document targets multiple architectures is great, most ASM tutorials online target solely x86 and as such give a very partial view of how assembly is written and how CPUs work, and on top of that x86 ASM is really quite a mess.

I've skimmed the document and it seems rather thorough and doesn't shy away from all the nasty details (which is a good thing for an ASM tutorial), the only criticism I have so far is that the assembly listings are a bit hard to read, additional whitespace and basic syntax highlighting (at least to isolate the comments) would make it a bit easier on the eyes I think, for instance: https://svkt.org/~simias/up/20180717-151848_asm-listing.png
This is an excellent caveat to the OP's post, which is good general advice. In my mid-20s, I was working 3rd shift, and a lot of hours, while my then and current GF was working a lot of hours on 1st shift. We had lived together for 5+ years by this point, but I was extremely discontent with life (as background, we had a great friendship that turned into an amazing relationship before the stress began to take its toll). Through a combination of always feeling like a zombie, feeling disconnected, lack of communication, just generally feeling terrible about life, and her being the closest to me, I became convinced that my unhappiness stemmed from our relationship, rather than my own immaturity meeting and external factors. Probably important to note that during this time I never lost respect, love, or admiration; I just questioned our compatibility.

Thankfully, I took time to question my conclusions, and I received some good advice from a good friends. I took some big steps forward in understanding my self and my relationship, changed jobs (no more 3rd shift), and the level of communication shot through the roof. Some years later, I wouldn't say we have a perfect relationship, but it's more perfect than I thought possible. There are still outside stresses, but we're steadying forces in each other's lives.

Definitely don't stick around people who make you feel terrible - or any kind of net negative, but many times when we're making these calculations, we're not in our most centered states, so be careful to make sure that the friend in question is the source of displeasure, rather than yourself/external factors.

The author obtains a legit free ticket from the organizers, which is pretty cool. I worked with conferences for a decade and as far as I can recall we never did this.

Back in the days, there was another way to access expensive conferences without a ticket. It probably still works in some locations. Basically, almost all hotels were equipped with camera/microphone in the lecture hall. This was broadcast on the hotel's TV system, so important people could do business from their room and keep up with the event.

These old systems had security in the TV itself; it was simply restricted from tuning in to certain channels (such as pay-tv), but the signals were broadcast everywhere. It's well known that you could get free pay-TV by bringing your own TV tuner. The same trick let you tune in to feeds from conference(s) hosted at the hotel - I know some famous talks from closed corporate events were recorded this way and distributed on the Internet underground... All you really needed was a room at the hotel.

Instapaper is not a subscription-based service. The product is completely free on all platforms today.

I think the app was a one-time purchase at launch but it has been free for many years. All of the Premium features were also made free when Premium was discontinued in 2016 shortly after the Pinterest acquisition.
It is usually overbooked though. It was great a few years ago when it wasn't very popular.

I'm not sure it's IP that's kept Wintel makers from doing decent trackpads. I think they just didn't care until recently.

I have both a 2015 13" rMBP and a 2018 Dell XPS15 on my desk. The Dell's hardware is really fantastic. Overall, it's not QUITE the equal of Cupertino, but it's easily the best Windows hardware I've seen since the glory days of the ThinkPad. The trackpad in particular, though, is just as good as the Apple one, I think. First time I've seen a Windows trackpad that was worth a damn, so I was SHOCKED.
Is this really true?

No, not really. First off, returning to the status quo is a sitcom thing, not a "pre-Internet" thing, but even then, characters change, leave and are introduced from time to time. Also, you can jump into a "modern" show and figure out any context you need to know pretty easily. I got into Barry and Curb in the middle of their seasons this year, and I still laughed through them...
None of your points apply to various newer Windows laptops or even laptops from years ago, such as my T450s. However, the smoothness still isn't up to par with a modern MacBook. I use the TrackPoint anyway, but the trackpad seems decent.

This reminds me of one of my favorite puzzles:

"Three wise men are told to stand in a straight line, one in front of the other. A hat is put on each of their heads. They are told that each of these hats was selected from a group of five hats: two black hats and three white hats. The first man, standing at the front of the line, can’t see either of the men behind him or their hats. The second man, in the middle, can see only the first man and his hat. The last man, at the rear, can see both other men and their hats.

None of the men can see the hat on his own head. They are asked to deduce its color. Some time goes by as the wise men ponder the puzzle in silence. Finally the first one, at the front of the line, makes an announcement: “My hat is white.”

He is correct. How did he come to this conclusion?"
What if the store I frequent happens to use one highway, but its competitor across the street uses another? I'd rather pay the "true" price of whatever goods I actually buy - transportation included - than be forced to subsidize the competitors' transportation too.

you're right, but I guess the problem for me is that I would just feel helpless if I went straight for being the fisherman. If you have a war chest from your corporate career, it doesn't matter if your area has political instability or crime or suffers from overfishing. You never have to worry about your kids wanting to go to an expensive school or getting a serious illness (at least, financially).

To me it would seem selfish to choose that life knowing that dependents (parents, children, spouse, whatever) might end up comparatively worse for it. Of course that's not a problem if you don't have any of those, or don't care
