I'd also be curious for actual numbers, but certainly on the commuter GO Train in Ontario, it's basically a 3-4 person staffing arrangement, with one person at the back, one in the middle in the accessible coach, and 1-2 in the locomotive. Adding someone whose job it is to roam up and down the train checking tickets adds 25% to the personnel cost, which is why most fares aren't checked.

But quite apart from the person and their ticket-scanner, there's also the whole infrastructure associated with fare taking— fare-free advocates argue that if you get rid of the machines and websites and apps, and all the associated upkeep, it ends up being a wash. Of course this only counts if you're getting rid of all fares rather than doing a one-off summer special.
Always blame the corporation that sold the person a bottle of coke, and not the piece of shit sitting on a bench, next to a rubbish bin, who drinks it then throws the empty bottle in the river infront of them.
I've lived in a dense urban environment before, and my personal experience is that I don't get pissed off about noises like trains or ambulances (both of which were a large percentage of the noise). There's just something about the raw audacity of someone _knowingly_ being an asshole by having very loud exhaust or music that gets under my skin. It just about drive me mad during the pandemic, where I felt I couldn't escape it - and ended up buying an in-town single-family house. My mental health immediately started to recover, and I truly believe it's because I'm now in a situation where my personal "noise space" isn't invaded as much by people who are _knowingly_ invading it.
No it wouldn't. You could say it's only for citizens of EU member states.

That's a restriction that wouldn't violate any EU law.
What do you mean? We have that now. Just pop to your local gas station.
Maybe this time it's because of rising energy cost, but I remember there was very same deal for short time, little more than 10 years ago when I was visiting there. If one feels adventurous, I can highly recommend buying this ticket.
Show HN: The most fair and transparent database benchmarks
Hi HN

https://db-benchmarks.com is a platform and a framework for making the most fair, transparent and open source database and search engines benchmarks. No more benchmarketing, because:

* anyone can easily reproduce all the results on their hardware

* the results you can see on the website are under version control on GitHub and anyone can run the same website locally in just a minute

* every byte of the project is 100% open source including test results and detailed test log

* the results are highly accurate with low coefficient of variation

The first release has Clickhouse, Elasticsearch, Manticore Search and MySQL covered on small / medium and big data realistic data collections. In plans: Percona Server, MongoDB, CocroachDB, FerretDB

Links:

https://github.com/db-benchmarks/db-benchmarks

https://github.com/db-benchmarks/ui

Disclaimer: I'm a member of Manticore Search team and the framework was initially made to compare Manticoresearch with Elasticsearch, but I did my best to not give any unfair advantage to Manticore since it's important for the team to understand the real situation. However, if you see something is missing or wrong feel free to make a pull request or an issue on Github. Or make your own fork with even more fair results!

Ask HN: Is M1 Pro screen brightness noticeably better than Air outside?
My laptop is a 2021 M1 Air, with a theoretical 400nits of brightness. Even under shade, it can be very difficult to see on a bright day outside.

The M1 Pro has 500nits SD (text/non-video) brightness, so therefore 25% brighter than the Air.

Does anyone have experience with both of these laptops outside? Do you find the Pro to be significantly easier to read in a bright environment?

Brightness aside, the Air does everything I need. An upgrade would be expensive just for better visibility, but it would be worth it if the difference were significant.
The proof of their experience is publicly visible. That is not the case for most individuals, including me.

FizzBuzz is not a puzzle solvable only with an obscure trick, and easily maps to real world, the buses problem too, and I can list more problems that are solved with 1-10 lines of code but the initial attempt used 20-50 because the structure of the problem was not fully exploited, unnecessary passes over the data, too much intermediate state etc. (all of the listed bloat appears in real world all of the time)

There are no tricks, no maths, no algorithms, no data structures involved. Your ability to pattern match these little bits should grow with your experience.
The link you provided seems to be a niche company that specializes in reconditioning existing vehicles. Not a manufacturer of new vehicles.
Huh. Wonder what the secret sauce is that apparently they can't release upstream. Open source FTW?
>Most trains I've seen have more than one conductor

At least in Berlin which this covers most trains/buses/trams have 0 people checking and there's a few people going on random ones to occasionally check so the ratio here is probably 1 worker to 50+ vehicles.

I can assure you, the amount of money a modified exhaust costs there’s easier ways to scare people and get them to jump. Open / minimal back pressure exhausts are done for the (minor in a non boosted car) performance gains. Not to scare people.

Even though I'm a software engineer, I had the opportunity to study literature and practice writing under some remarkably amazing teachers and professors.

Now, at fifty, I regularly practice that skill and it's served me quite well. The process for me starts with a strong realization, feeling or epiphany. The exercise, then, is to take that thought and scaffold it with words so that the entire thought is clearly understandable by anyone (and hopefully expressed with some cleverness).

As David Lynch said, if you sit really still, those big ideas deep down there will start to surface and it's your job to make them real. They want to be something.
Normally DB day tickets, even bought at the ticket machine, are not transferable. You have to write your name on the back - in theory, before the first time you encounter a ticket controller - and be prepared to produce ID matching the name.
What trains would that be? Street cars and busses are the only ones I can think of that don't have first class. Everything from the S-Bahn and "up" has a first class car or section.
I think most people would prefer focused work instead of more office idle time. think less days (hopefully) lead to less meetings (hopefully) lead to better time management.

The depths of the pandemic were the golden years for street racers since the lockdowns meant no traffic. I live in OakCliff which is a neighborhood just SW of downtown Dallas. There are so many semi-souped up Dodge Challenger and Chargers it’s a running joke. Very loud, very annoying, plus they kill some poor innocent bystander about 4-5 times a year.
Often, not even that much, as the check is just one of many jobs the personal has to execute. The other jobs won't disappear just because they might not check now.
Not even that. Most lines are already at maximum capacity, and the number of cars is usually dependent on the shortest platform on the line already.

We take this so seriously, any stop, even unplanned, where the doors might open aside from absolute emergencies must be on a platform of sufficient length.
thanks. I hadn't seen these--probably not in the US. I do like the idea of reducing waste.

The coca cola plan to make all their bottles from 100% recycled plastic was apparently delayed because they couldn't buy enough recycled plastic, which suggests there is a chicken and egg aspect to this.

> The thing about pure black isn't that it's unnatural, but that when paired with white its contrast can actually be uncomfortable and less accessible than a slightly toned down color combination (especially on full brightness).

For those with fuzzy vision (obviously an extremely common situation), contrast is reduced naturally when the black and white bleed into each other. Reducing contrast harms those users, belying your "actually less accessible" assertion.

I recall two-liter resealable glass bottles of Coca-Cola before everything switched to plastic. A quick search shows that these could be returned for a deposit.
Why would the city do anything about the vehicles? They'd lose their scapegoat if they did that.
Both VLIW & Ooo Superscalar are doing a different tradeoff to achieve similar goal - maximize ILP.

With VLIW the compiler unrolls the code and tries to find the parallelization but has no control over runtime stalls and results in larger code size. The complexity is in the compiler while the machine is simpler.

With an OOO superscalar machine, you have to dedicate significant piece of HW for stuff that would be easily done by the compiler. The advantage is you can get reduced code size and better performance for non-linear code.
Not sure why this is on the front page, but to clarify it's required by the FCC [0] for carriers. Microtik, just like every other network vendor, has this in their product (port mirroring for law enforcement) so that they can check the box. CALEA has been around since the 90s [1].

Kind of, but you'll have to take the scenic route (long distance trains IC/EC/ICE are not included).
There’s only one left, all the others went bankrupt, and that one (FlixBus) only offers long-distance journeys, while this ticket only applies to regional trains.
These days we're more likely to see comments of the "HN is hostile to crypto" variety.
- Accusing a user of using a slur

- Getting snarky because they did the reasonable thing and got rid of the slur after it was pointed out

- Calling said user a dick. If Karen is a misogynistic slur, How is dick not moreso misandristic? I realize you said "dick move", but that's functionally the same. Saying something was a "c?nt move" or a "n????r move" would be tantamount to calling someone a c?nt or n????r.

- Because maybe it made your comment "look stupid"

Jawdropping desecration of the guidelines. You need a vacation.

The single market. Refusing to sell to other EU citizens is very illegal.
If people use the train instead of their cars, it will save energy by a lot. Trains are the most efficient form of transportation, cars the least efficient.

Pretty sure they wouldn't be making any profit at 15e or 27e either.
Thanks for the detailed comments. To create the first version of the taxonomy, we looked at the 50 companies we worked with doing modeling on their existing analytics data (from GA, Adobe, Mixpanel etc) and mapped their product UI’s and data team requirements into one extensible data format. In your examples, the taxonomy would classify these as interactive user actions, with a PressEvent on a Pressable UI element. This way, models can work both on the GitHub and HN examples in one generic way, so there is no need to come up with very case-specific naming and map these once you build a model. If you still have use-cases that are not covered, the taxonomy is also extensible, which enables you to use our validation & data modeling.

About replacing components: no need to do this if you don't want to, you can either:
A) Swap native components without having to code anything, using the premade Tracked<Component> for a specific platform (e.g. `<TrackedButton onClick={handleClick}>Click Me!</TrackedButton>`); or
B) Use your own component of your liking (i.e. Next.js' Link) and wrap a TrackedContext around it that automatically triggers an Event (e.g. see https://objectiv.io/docs/tracking/react/api-reference/tracke...).

We're big fans of Snowplow for scalability and have an early integration where you can run Objectiv data straight into a SP pipeline https://github.com/objectiv/objectiv-analytics/tree/main/bac...
I think it depends on the total number of hours per week. If we assume 40 hours regardless, I’d rather spread it out over 5x8 than work 4x10. Ten hours is just too long - even after 8, I’m mentally cooked.

If we’re shortening the work week by 4 hours, I’d rather take that as a single afternoon off. 4x8, then Friday is a half day (vs shortening 5 days by a fraction of an hour).

If we were to go to a 32 hour week, I’d probably want to just do 4x8 and have a 3 day weekend. That allows so many options for short trips, major home projects, camping, going downtown, etc. With the current 2-day weekend, I always feel torn between doing things that are fun vs doing chores. It’s never quite enough time.

Nope. If I can't file a ticket or call and get an issue fixed, that's not support.

Ah, that _is_ a great difference then.

Hopefully they get their Linux act together.

Officially, it is not free in order to gauge demand.

Personally, I think there is an ideological and pedagogical element. They don't want people to get used to the idea that something like free transportation is possible.

I heard an interesting talk a couple of years ago about university tuition fees. Germany has fairly low fees compared to other countries. At some universities it is more like a token fee, a couple hundred € per year. Many students get living expenses paid from the state anyway (BAFÖG). It is silly to then pay back some of that immediately. But the thesis of the talk was that the tuition fees were introduced for educational reasons, not to cover the actual cost of teaching. Students were supposed think of themselves as customers, and of education as a good. And they could back this with quotes from neoliberal think tanks. As the FDP (free market 'liberals') is in the coalition, I'm sure one precondition was that the ticket couldn't be free.
Are the caps made of the same exact plastic as the bottles? If not, then these become mixed-type-plastic and cannot be recycled by most [UK] authorities.
Likely extremely busy - at least on the inside - because there's essentially no wiggle room in the form of extra vehicles or personnel.
And I can't wait for the usual politicians from FDP and Union to draw the conclusion that free or cheaper public transport will forever be unfeasible, not that we need to invest more into the rail network.
They are. If you can squeeze an english translation out of this somehow, the article considers some potential problems:

Movie data isn't that valuable information to protect for an individual. Instead you can try making a contacts syncing software, or email storage, or even WhatsApp media backup system.
I would argue making it free and keeping it free would have been a cool move.
- Less/no expensive accounting
- Less/no personnel for checking tickets
- Less/no personnel for prosecuting people who don't have tickets
- Less/no ticket vending machines (and all the maintenance that comes with it)
- Less traffic on the roads since you can't beat "free" and hence less emissions (at least in hamburg trains operate on green energy) and less wear on the roads (might be offset by the wear on trains and busses)
- Fully non-discriminant with respect to income

I have no idea if that would work for inter-city transport but for inner-city transport the HVV for example (the public transportation network responsible for hamburg and surrounding areas) sells 30 million tickets a year and I wonder how much it truly costs them to do that with all the relevant factors mentioned above.
It’ll move energy use from highly inefficient personal vehicles burning gasoline to highly efficient trains using mostly renewable electricity, during the summer where more than enough electricity is available.
Indeed, when comparing trains to airplanes, the time necessary to get from the city to the airport and the security checks & boarding time are generally forgotten (repeat at arrival). It's generally around 1 to 3 hours for a single flight.

So, for a short flight, using the train may take the same time than using the plane (particularly true in Europe with the speed trains).

For example, Paris-Frankfurt, next wednesday with Deutsche Bahn ICE 9553 it's 4 hours for 56€ from city center to city center (cheapest price for the week, it can go up to 350€). By plane, with Air-France it's 1h20 from airport (CDG) to airport (FRA) for 127€ the same day. From Paris center to CDG airport, it's around 30 mins, and for Frankfurt airport to Frankfurt center it's 40 minutes. Both ride by local trains (for 5~10€ each). All in all around 2h30 from city-center to city-center, but then you need to not forget the necessary time for security check & boarding. Let's say 1h30 only because you have no luggage... If you have a luggage add 40 minutes more.

All in all, for this ride, the time is around the same, but the stress is not...
The issue isn't whether people put plastic waste into recycling bins, it's about whether any of that plastic gets taken out of the bins and re-used in commercial processes. Today, across the entire world, that answer is essentially no. Yes, there are products made with recycled plastic (Coca Cola is the current poster child). They are rare because its considerably more expensive and more difficult to work with recycled plastic, and most are made primarily with waste from manufacturing processes not post-consumer waste (I suspect Coke's volume is high enough that they need to tap the post-consumer stream but I haven't found any data on that).
Here's one thing people who don't live in NYC may not understand: many streets have built up buildings on both sides. In an open area with normal low-density houses a lot of sound would dissipate into the open air. In NYC it reflects and makes the effective volume much louder.

Sirens seem to be calibrated for open air environments and they end up being perceived way louder than they actually need to be. I really wish the city would fix this because it's a solvable problem. Just dynamically adjust the volume based on how much sound is reflected.

Anyway, this makes these open engine straight piping vehicles just that much worse in the city than they might be in suburban Ohio. I also understand the argument that being loud for a motorcyclist is a safety issue. At least I am sympathetic to that at 50+ mph. But in the city if you're not driving on an expressway, a parkway, a freeway or an otherwise major road (eg the Van Wyck) then you're simply not going above 30mph, probably not even 20mph.

I've had cases where one of these idiots passing actually causes things to shake in your apartment. That's not a safety issue. It's a "deliberately being an inconsiderate asshole" issue.

That all being said, the NYPD seems to have SWAT teams at the ready for black teens who have a joint or jump a subway turnstile but, at least in my experience, they do almost nothing when it comes to traffic enforcement. In over 10 years of living in NYC I think I saw the cops pull over 3 people. Blocking intersections is rampant. Running red lights is rampant. And this is without even getting into parking violations (eg blocking pedestrian crossings, parking in bike lanes, blocking fire hydrants).

So will this noise law even be enforced? I'll need to see it before I believe it.
I rarely comment but PBS Spacetime is an amazing channel and Matt a great host. Even though they don't (hell, I don't) understand it all, I love watching it with my kids and see their eyes get huge when they see the excellent graphics and concepts.
Cannabis can very well lead to dependency, I struggled with it for the majority of my adult life. I totally agree that illegalising it is laughable and it's by no means as dangerous or easy to get addicted to it as is the case with benzodiazepines, but it is also no joke. Of course I am talking about "recreational" use, not medical.

I really dislike the handwaving nature with which the very real and especially psychologically quite harmful side-effects of Cannabis are discussed for the most part. Mind you, I believed it to be harmless for the longest time, too.
> I have never understood how these cars and bikes are allowed to roam the streets like they do openly all day and all night while police used to be so quick to arrest youngsters who jumped turnstiles or smoked weed.

With the crime wave NYC is experiencing, is there not more important crimes to focus on?
