This might be hard to believe, but if events are at the top of the most used social media sites, it’d be pretty ignorant to think awareness is isolated in any way to social media. You’d have to have been living under a rock to not have heard of these derailments last week.

They went for years without fixing the flaw. Only TikTok exposing the flaw widely caused enough outcry to make them change.
Ah okay yeah that's a huge issue.
I've got the same experience.

Chinese manufacturers can do absolutely amazing work - provided you can get them to care. In general they'll manufacture exactly what you ask them to. They are also very happy to do manual labour to get the job done.

But for most stuff, don't expect too much feedback. Asking for feedback on a design to optimize it for production didn't really produce anything useful, and they manufactured designs which contained obvious mistakes.

In general, you simply get what you pay for!

Solution seems simple to me: build more bike lanes and bike paths, especially in cities.

Although honestly, sharing a road with cars isn't that big of a problem as long as car drivers are responsible drivers. Put more emphasis on interaction with bicycles in driver license tests, and keep the murderous idiots that you get in some countries off the roads.
Yes, but.... if you look at the paper, most of these lamps have some degree of lower wavelength light production. Some of them mitigate it through the glass they use, some of them make it worse. There is no good or easy way to tell. :(
On my M1 MBA, it's sluggish but still usable. Definitely worse than on Windows. It's probably the worst out of the few Rosetta apps I have. It's a little funny. The Steam client performs worse than any of my Mac games that are also using Rosetta. A simple client falls over more than a game which is (visually at least) doing much more complicated things.
> This could hurt basic static analysis.

That’s a good point. I know some of the python static analysis tools can “see through” some simple indirection, but don't know if even a simple wrapper injecting arguments would work with any (or which) of them for this purpose.

> it's not clear how to balance a fresh perspective vs. an experienced (normalized? tainted?) view.

Having a healthy, balanced view comes from enough experiences. Ideally from working in a bunch of places and seeing enough things go sideways, and correctly understanding and identifying the causal chain that led to failures.

Funnily enough its sort of like training an AI - you essentially need a lot of correctly labelled data to learn. Junior engineers don't have enough data points, and unfortunately some "senior engineers" I've worked with took (in my opinion) the wrong lessons from their experiences. (Eg the CTO who thinks version control is too complex.)

The interesting cases are when smart, experienced people disagree on what the best solution is. Should you keep your team small and smart or have a varied team with more mentorship and process? Is code review worth it in every case? What is the right amount of tests for your software? How often do we want to push to production?

When I was teaching programming my students would sometimes ask juicy questions. My favorites were the questions I could answer with "I'll tell you my opinion, but I've worked with people I look up to who think I'm wrong about this..."

Which ignores that even 0.001% of traffic is a load of more skilled bad actors, this IP space is rotten to the core.

Throughout, I have stated 0 downside, all upside. Even one dedicated hacker gone, is a plus in this scenario. Even showing yourself to be actively, aggressively defending is a plus, if comparables are less guarded.

And you're bracketing the use case, others and I have been speaking of the generic. Many run MTAs, so cutting down on inbound spam and malware, pre-filtering is a plus.

Canning all this address space is a never lose, always win, plus plus plus.

Your point that sometimes it's better to shoot for a mediocre solution to remedy a problem is valid; perfect being the enemy of the good and all.

In this case, though, it seems incredibly evident in hindsight that the trade-off here was not, in fact, the right call.

The thing about bypassing safety valves is that you need to be really sure that you're not just creating a bomb that's going to blow up down the line.

In the case of earthquake regulations that were passed in response to a history of earthquakes, it's pretty hard to reasonably assume that the trade-off would be worth it in the long term, hence the outrage.
taken literally you seem to be saying that there are costs other than energy involved in atmospheric carbon capture, which is too obvious to be worth saying; your capex and non-energy opex costs can be low but they obviously can't be zero or negative

do you mean more costly than the energy obtained by burning it, because that's a small edit that converts your statement into an assertion that's at least coherent

if so, no, the cost is about an order of magnitude smaller; though coherent, your assertion is still wrong

quoted accident statistics from the 1970s where it seemed every scenario other than the “cyclist gets hit from behind by a driver out of ignorance or malice” such as “cyclist hit dog”, “cyclist hit parked car” (my worst cycling accident of all time), “cyclist hit cyclist” (I still think cops oughta arrest cyclist for rising in peloton), “cyclist got hit by driver in intersection because the bike lane had no visibility where it crossed the road” killed more cyclists.

Newer accidents statistics seem to show the “hit from behind” accidents happen more than previously indicated, particularly in the American South.
As the saying goes, Americas worst ideas are always bipartisan. The whole decoupling from China hysteria is going to cause significant harm to consumers and people vastly underestimate how complex manufacturing at the scale, quality, and price is that China built out over the years. There's an incredible amount of tacit knowledge in industrial processes that cannot easily be replicated, it takes a long time to develop.
> bear in mind that China literally started producing electronics in the 80s, a 40 year headstart

Pretty sure Indian electronic manufacturing didn't start with this Apple project.

I believe they said UX. to me, Spotify has always been an example of good UI, but not so for its UX

Spotify used to have this great thing where if you long-pressed a song, it’d play ~15s from the main hook. it was amazing for quickly getting the sense of a playlist or recognising a song, but they removed it because not enough people used it.

and there’s the big one everyone talks about: Radio. Spotify radio used to be fantastic. in goes a song and out comes exciting new songs, with a few you know sprinkled in. for a lot of people I know, this was why they chose spotify over anything else

then at some point the metrics will have shown that - shock! - people prefer songs they already know??? so now radio crams in as many songs you know as the genre will allow

of course the numbers show that people like what they’re already familiar with! but that’s not the point of a fucking radio
That is true. But one could argue that some like #2 are doing opposite at a macro scale.
I don't disagree with you but I think there is a sort of difference that makes the comparison to software developers[1] a bit false. The cost for software developers[1] to fix things after the fact is generally lower than the cost of developing it again from scratch - the cost for contractors to fix an existing fully constructed building that didn't have rebar put in is... tear it all down (expensive), dispose of all that waste (expensive), probably double check the site to make sure things in the ground didn't shift during the construction and destruction (expensive) and rebuild the building from scratch.

Personally I'm against amnesty for contractors - if a building was poorly constructed the people responsible for that decision should be treated harshly... but I think there is a reasonable discussion to have around amnesty for the buildings themselves.

> and no build server

Personal experience is that a build server normalizes deviance. "But it works on the build server" we used to say, as, with time, it become harder and harder to build locally. "Just fix your environment!" we used to say, when it was the build system that was actually at fault. "It's all so fragile, just copy what we've done before!" we then said, repeating the mistakes that made the build system so fragile.

Eventually, the build system moved into a Docker image, where the smells where contained. But I'm still trying to refactor the build system to a portable, modern alternative. If we hadn't had a build server, we'd have fixed these core issues earlier and wouldn't have built on such a bad foundation. Devs should be building systems that work locally: the heterogeneity forces better error handling, the limited resources forces designing better scaleability, and most importantly, it prevents "but it works on the build server!".
> in effect that's the case.

When it's private organizations agreeing to rules about what they will or will not advertise as a bedroom for the purposes of commercial communication, that's called "capitalism" not regulation.

To your other point, not all regulations have to be about safety to be valid. Preventing what is effectively false advertising ("bedroom" has a presumption of privacy for the inhabitant that is belied by having to traverse another person's private space) seems like a valid use of regulation. You can still sell the house, and a buyer can still observe that the room is usable as a bedroom, but you can't advertise the house as having a bedroom that a reasonable person wouldn't consider such.
Awesome site....simple and intuitive yet powerful
This happened to me. Was the sole developer on a certain service. Other engineers would use the service at the company, but no one else really wanted to get into it and work on it.

Was working on fixing an issue one morning, got roped into a meeting, and escorted from the building. Next week, saw an email from a coworker asking how to do something with the service. Told him, politely (don't burn bridges) that I didn't work there anymore and wasn't interested in helping that company without payment. Yeah, it might be thought of that I hung him out to dry, but that wasn't my intent. I just won't work for free, particularly when I was booted without much chance to get my affairs sorted
The guy worked there for 9 years. That's a really long time, longer than many posters here's entire careers (mine included), and longer than most of us will ever work at a given job. Of course he's going to be emotionally invested, and knocking him for this is a bit cruel.

Not so long ago, your kids _would_ know you as someone who drives buses for the local bus company, delivers the post, or works down the mine.

> "If I had my way, downtown areas would have very low speed limits, and narrower streets would discourage cars from going fast."

Thankfully, this is exactly the sort of urban design we're gradually seeing more of, at least in many bigger European cities.

New UK Department for Transport guidance is for all urban and residential streets to have 20 mph (~30 km/h) speed limits, down from 30 mph previously. It is, however, still up to local authorities to actually set those limits. In London, most streets have been 20 mph for a while now.
> i am not sure how this could have been unclear from my comments above.

It was clear. I am just saying that photovoltaic is very far from replacing fossil fuels.

> this transition is already happening and will be essentially complete within a decade

I guess let's see that. Also photovoltaic energy depends on the weather, it's not exactly something we can control (unlike fossil fuels or nuclear energy).

> that has never been a problem so far in human history

Well I think we can say that energy consumption in human history is largely correlated with fossil fuels, can't we? But I did not say that there is no market. I said that it's not clear whether we can make it work _at all_ without fossil fuels and without reducing our consumption.

> the issue is that it would be bad to turn the planet into venus.

Yep, but the biodiversity problem is not even related to climate change: we are destroying life on Earth just because we have the energy to do it. The fact that, on top of that, this energy is creating big problems that still have to happen (climate change) is just adding to the problem.

We should just drastically reduce our consumption, both because cheap energy is not a given for the future, and because we should care about not turning the planet into Venus, or Mars.
Ask HN: What software do you love?
Since it's Valentine's day today, let's write a love letter to our favorite software :)

I'll start: Postgres - there's nothing this workhorse can't do and it keeps getting better. Also, it has never let me down.
Just to be clear my oldest, now in 8th grade does ask occasionally to have a phone still. I gave her a pre-pay flip phone for emergencies, it can text and call, that's pretty much it. She also has a simple mp3 player for music that I put mp3s in, no internet access.

They also have access to Youtube using my old phone. However, I have very clear rules about Youtube, which I can share if someone is curious. Finally, they have Amazon tablets with parental settings for their age group, and pretty much everything disabled except for books and kid apps.

I'm explaining all of this so people can understand that they have access to some electronics. Basically, I have covered some electronic needs that they have like music, watching an occasional video, play video games.

One of the advantages is by having specific devices for specific things I know what they are doing without having to watch over them.

Youtube is the biggest exposure my kids have. I have my account logged in, so I can see what they watch, they know this. With no adult settings. Moreover, there is only one time they are allowed to watch Youtube it's an hour and all 4 of them take turns. This has actually created something I didn't expect, it forces them to find common videos they can all enjoy, or they just won't watch at specific days that the videos are "boring".

If I look at the history and find a problematic video I will set expectations, reminders and sometimes I outright block certain channels. What's interesting is now that they have been doing this for a few years they monitor themselves. I hear them say "we can't watch that, find a different video".

To answer the other part of the question of do they "healthy social lives". They do. I actually thing social media gives you a false sense of socializing. "Look at all the friends / likes I have". Instead, my kids actually talk to other kids or play. My oldest is more into hang out, draw, listen to music kind of thing. Overall, my wife is really social by nature, she has what I call people magic, so my kids have learned to emulate that. We coincidentally moved to a new house this year, within a week they had established multiple friends and befriended the entire neighborhood.

Boredom helps, we all try to avoid it like the plague, but being bored allows you to become more creative. My kids go outside more, it helps that I have 4 because they can play with each other if no one else is around.

I don't want to pretend my kids are perfect, and I am an amazing dad. They have faults, so do I, a lot of them. To me the key is setting clear expectations and explaining the why. The joke in my house is they will probably learn how to drive before they have a cellphone. Honestly that might happen.
I would guess that completely incompetent IT departments that only degrades everybody's work are very highly correlated to workplaces that use those huge, all in 1, hired consultants based software packages.
There isn't really any "we technologists" that can collectively decide to stop the madness.

The book “Car Free Cities” is a beautiful imagining of what would be possible if we built from scratch, attempting to connect concepts in cities like Venice that actually are car free.

The book itself is a beautiful physical object. I really wish we could do cities from scratch.

Reasons I _want_ to use Arch:

- Almost always up to date software

- Little to no patching/changing upstream

- Follows upstream defaults/best practices

Reasons I shy away from Arch:

- Too much churn on keeping things up to date

- Package maintainers are hit or miss, don't seem as engaged as Debian

I'd like to use Arch on my servers and devices, but it seems like it requires more responsibility than using Debian vs the benefit of using.

More importantly, I think more accurate nukes along with good satellite multispectral and signals intelligence means that top generals carrying out orders for nuclear first strikes can be more certain that they're signing their own death warrants. Hopefully this results in any leader ordering a nuclear first strike getting deposed by military coup rather than starting a nuclear war.

How are the keys indexed and looked up? How does it handle disk fragmentation? This has always seemed to me to be one of the harder problems with databases.
See my reply to the original question.
If you're willing to go a bit further, i recommend adding a "groove" cursor, that slightly shift each box within the beat, at random (then you can have more complex algorithm to make the randomisation move the beat toward a ternary rythm instead of completely at random). It's called "humanize" in some audio software and can be fun (if you feel like putting one cursor per track, that's even better).
Of course they do!?! How is this even a question? Unless you’re a run of the mill mba grifter desperately trying to push short-term “shareholder value”..

This article has basically no content. And despite the subtitle saying that it was prompted by Tiktok videos, there isn't a link to Tiktok either. Just how is this AI-powered? Is the AI trying to predict what you want to order? Is it speech to text? Something else entirely?

In a civilized, democratic society that's always true. But it doesn't disqualify the original point.

And it works both ways... Other people have spent trillions of US dollars on, for e.g., the war in the middle east. Some of my tax money went to that. I didn't have the ability to veto it.

There should be a reasonable public debate and then people vote. Very often it involves spending other peoples money. That's just how it works.
