Triple-Digit Heat, but No Electric Bill?
That sparked a thought: Considering how global all supply chains are nowadays, would the disruption sparked by the first big impacts of climate change be better for the climate, or worse?

Let's say most of the markets for luxury goods crash because of poverty due to mass migration and food and water shortages. That would be a net benefit to overall CO2 emissions, right?

Hi, kubkon here, the author of Zig's MachO linker. I just wanted to explain our reasoning here a little bit. As you have hopefully noticed in the release notes, there are 5 core team members that are paid either full- or part-time for their work on Zig. That's not an awful lot, and as you can see in our latest roadmap for 0.12 release, we have quite a few challenging components to develop including functioning linkers for the most common platforms, and not only macOS/Apple. This makes it really tricky to justify spending a considerable amount of time trying to support an OS that was officially dropped by a vendor such as macOS/x86, or watchOS/arm32 (FYI, as a fun fact, arm32 is considered private as opposed to public by Apple according to comments and conditional includes in Apple's libc headers). That said, after 1.0/stable release of Zig, I would love to spend more time into adding backwards support for old Apple platforms in the MachO linker and Zig as a whole.
I'm thinking coil guns instead. Room temperature superconductors don't solve the rail erosion issue with railguns, but I think should greatly increase the performance of coil guns.

My thinking is that zero resistance through the projectile itself and through the rails would help, but you still need to make an electrical connection between the projectile and the rails. Either this is done with a plasma arc or physical contact, but either of these causes erosion of the rails even if there is no electrical resistance through the rails or projectiles. Am I missing something?

> People who stay married might just do so because they're afraid of being alone, and so suffer in silence for the rest of their lives. People who have been through many relationships maybe know they'll be ok if they split

I used to think that, esp after seeing the unhappy but still together couples in my parent's generation. But the main issue is that now as I'm older and have a bunch of friends the second category now, and the unhappy couples in my parent's generation are (relatively) happily co-grandparenting together. Whereas this late-30s divorced/never-settled couples are equally (if not more) miserable as some of those unhappy couples were in my parent's generation.

I don't know what will happen to my divorced/never-settled friends when they reach the grandpa generations without grandkids, but most likely they will find similar people like each other to give each other company. I do trust them that they will do something to be happy.
My wife and myself have slept around and had previous longer relations as well; I see it as a positive. How do I know what I like from a relation or sex if I didn't shop around? I had extremely bad and incompatible partners/sex and now I know that would never work. When I see people on reddit/twitter talk about their relations, I sometimes wonder if people married or living together actually ever talk; it's so incredibly dysfunctional and broken. And then they wonder why people take off, cheat etc etc as they have 0 bond after being 'highschool sweathearts' for way too long and growing apart for all that time. Few kids 'to save the relationship' of course.

IP is not a text format (like HTTP). It's a binary format where each field of the IPv4 header has an exactly defined offset and length. The source IP address is placed at offset 96 and has a length of 32 bit, the destination IP address sits right afterwards with the same length. Changing anything will result in new protocol definition, et voilà that's IPv6.

I couldn't make sense of the 100-m race one either. The only thing I could come up with is maybe the clock freezes/race ends when the first person finishes, and the scores are then done by distance to the finish line.
Oh I completely agree with you that folks on HN are likely to be of a particular mindset when it comes to technology purchases.

However, that doesn't mean that every non-HN user out there buys the aluminum-shell-in-the-vague-shape-of-a-laptop and doesn't make a conscious choice.

My point still stands. The GP doesn't have the data to back up the assertion.
I think people are missing a huge impact that GPS has beyond positioning. GPS transmits timing signals. Those timing signals are used in industries throughout the world to sync transactions. Without which, you are left to syncing via potentially untrusted clocks. Finance [1] is a huge example of the ubiquity of adoption of GPS timing.

I don't count ChromeOS or Android because they're even more locked down than Windows or the Macintosh. I don't care about the Linux desktop. I care about people using a system they can control.

If FreeBSD got substantial market share that would be a victory. ChromeOS gaining market share, and especially being used in education, is a defeat.
I've heard all my life that the climate system is fiendishly difficult to model (which seems true enough to me), and nearly always in the context that perhaps the undesirable predictions of these models may not come to pass (AKA climate change denialism). To me, the unpredictability of making measurable changes to the composition of the Earth's atmosphere is a reason not to do it; not an excuse that can do whatever we want with no repercussion. I'm pretty sure this all ends badly.

I do think one of the major components is the economic system, I never said it wasn't. I believe a reform of the economic system will still be better than nothing, never said it wouldn't. I would like nothing more for the mechanisms to be eliminated that have made the powerful people, because they are certainly drivers in this disaster. I still believe in doing everything possible to mitigate it and changing everything we can...but let's not kid ourselves, our general mentality that makes us think short-term has also given us those powerful people...it's not like "little people" aren't to blame either.

The sooner everyone acknowledges their responsibility, the better. Of course, I still think we will suffer due to what we have done but I believe in doing everyhing we can to change it. Of course, you were snarky because I was snarky at your other comment first. Tit for tat.
In my experience, the documentation is great for most of the major libraries and the common path.

Once you get away from those things get sparse. Several really common libraries have glaring omissions (or entirely missing) module docs, and others just barely cover the common web use case.

It’s not uncommon for me to have to open the source code to try and understand what some function actually does.

Elixir is still my language of choice and has a better docs ecosystem than most languages but the community demonstrates a bit of a blind spot also.
The Wilhelm scream is a classic, but I always find the Howie scream way funnier. It’s so much weirder and finds itself jammed into more diverse uses, I think cause it has a little bit of an inhuman or non-vocal quality to it.

With the realization that the first culprit is being 8 billions on earth. I'd love a society where, say, 50 million humans would all live in abundance and luxury.

But apparently the goal seems to be to pack tens of billions of people living in high-rises "because efficiency".

As if having ever more humans on earth was somehow something to aim for.

Concerning combinatorial optimization, for what it is worth, I've been working in that field for the last three years! Mainly on public transport optimization algorithms.

Speed is correlated with execution quality. All else being equal, A lab which is better equipped - with better access to materials, and motivated and competent researchers will deliver before the equivalent lab which is deficient in any of the above.

The failure of various smart glasses (and the AR/VR vision more generally) seems to punch a hole in the argument that in industrial capitalism consumer wants are manufactured. Companies can push very hard with marketing but there needs to be a minimum "click" with at least some consumer demographic for the magic to happen.

The article mentions privacy concerns, hardware / quality issues etc. but this does not feel like a coherent explanation. The masses have been conditioned not to worry about their loss of privacy and first adopters tend to be accommodating of usability and quality issues.

Somehow all this "tech stuff on our head" has hit a cultural and/or user experience barrier that is non-trivial to overcome. Yet it is hard to pin down the real reasons: Billions are now entirely happy with "tech stuff in our hands", tech that is privacy violating, has been of varying quality, creates potentially dangerous distractions etc.

I, for one, am not impressed by his Twitter thread. It looks very sloppy, and I am completely disregarding videos of floating flakes of gray whatever-the-heck. They look like they have none of the equipment to properly test what material they created or what its properties are. It doesn't inspire confidence, it's just more damn attention-seeking. Stick to rockets or whatever.

That said, the fact that LK-99 has not been instantly debunked makes me somewhat hopeful that even ridiculously sloppy attempts like this did manage to create a bit of the crystal lattice that makes this material unique, and that, if indeed it does have superconducting properties, the manufacturing process won't be hard.

In general I agree, but a couple of IMHOs:

> that there is only one C

IMHO one of C's strong points is the ubiquity of non-standard compiler extensions, C with Clang extensions is much more "powerful" than standard C, personally I see C as a collection of closely related languages with a common standardized core, and you can basically pick and choose how portabel (between compilers) you want to be versus using compiler-specific extensions for low level optimization work (and in a twisted way, Zig is also a very remote member of that language family because it integrates so well with C).

> "one notch up from assembly"

C is actually a high-level language, it's only low-level when compared to other high-level languages, but much closer to those than to assembly. Arguably Zig is in some places even lower-level than C because it's stricter where C has more "wiggle room" (for instance when it comes to implicit type conversions where Zig is extremely strict).

> being available on any platform, existing or future, any architecture, suitable for any bare metal use case

Zig has a pretty good shot at that requirement, it has a good bootstrapping story, and for the worst case it has (or will have) a C and LLVM (bitcode) backend.

For me personnally, Zig will most likely never completely replace C, but instead will augment it. I expect that most of my projects will be a mix of C, C++, ObjC and Zig (and Zig makes it easy to integrate all those languages into a single project).
I never understood this take. You shouldn't be heap allocating each node in your linked list anyways. It's trivial to convert the pointer fields to indexes and have each nodes live in a `Vec` unless you need it to be intrusive. You'll get better performance anyways because you're not doing a pointer deref and blowing your TLB up every time you traverse the list.
Clearly, I meant conservation of rotational momentum, not conservation of linear momentum.
Firefox is NOT made by a nonprofit, that's the problem. It's made by a for profit corporation using the shell of a noprofit to claim legitimacy. This for proffit Mozilla Corp is primarily funded by an ad tech company and has itself dabbled in ads multiple times, contrary to the interests of the userbase that the nonprofit should be looking out for. These aren't minor misteps but repeated deliberate decisions to ignore user preferences.
It's definitely not that black and white, because they're not directly measuring people's happiness, they're asking them to self-report their relationship satisfaction.

If I had a mediocre partner but I thought that was just how relationships were, I'd probably report being "satisfied" with them, even as I wished relationships weren't such frustrating things. If I thought marriage was an unbreakable bond I'd probably also avoid admitting I was dissatisfied with my partner to anyone (even myself!) as a coping mechanism as well.
Cory is kind of the Jello Biafra[1] of technology. If you go back and listen to some of Jello's older spoken word albums... damn. The guy is right, a lot. Also extreme and definitely not for mainstream audiences -- which is unfortunate because those audiences really need to hear his message.

But it's delivered in a way that is wholly unpalatable to anybody who's not already close to his thinking.

I suspect that it's a translation in English of (a form of) the word "verkakte" (also spelled "facacta" ).

The new English word has a more specific meaning though.

Given how the market sold Google after their Bard press release had incorrect information, I'm quite skeptical of everyone's opinion on AI since its a bunch of people who are new to the market and enjoying the hype.

The counter-argument is that you are "unfairly" shifting the cost to others assuming that if a workaround wasn't available you would have paid the premium price. Let's say that it is expected that 1/3 of people will purchase heated seats. If you unlock your seats without paying then you are harming Tesla because the heated seats package was priced assuming that 1/3 buy it (so it was priced at 3x the per-car hardware cost plus some markup). Now less than 1/3 people buy it (as they are hacking it to be available) so it was underpriced and they lose money. Next year Tesla adjust their expectations to 1/4 people buy it and accordingly raise the price of the package (Now 4x per-car hardware cost + markup because it still has to cover the cost of installing the hardware in all cars). Now you are harming the people who are buying the package because they are paying for the cost of the hardware that you are using without paying.

> They sold you something in its entirety, including the seats with wires.

This is the part I have to agree with. There should be nothing to legally prevent me from doing whatever I want with my hardware. It may be unethical to use this hardware without paying for it, but I shouldn't be legally prevented from doing it. They did sell me this hardware even if the cost was paid for by those buying the heated seat package and I should be able to do whatever I want with it.

I think this works quite well with things like CPUs where they blow hardware fuses to disable features and it is infeasible to restore this functionality at any practical scale. However for things like seat warmers where the controller is likely easy to bypass (and in this case the lock is actually implemented very far away in the infotainment system) it will likely turn into a arms race between tamper-resistant hardware and those who what to unlock the feature without paying for it.
I mean, if someone has been right multiple times maybe you should take them seriously despite them not being cool enough for you in some sort of nebulous way...

You may consider the electronic design automation (EDA) industry. Basically, the tools used to design the ASIC we love.

The industry anticipates a job crisis, with elder people retiring, a shortage a new entrants (not see as sexy) and still a strong need. There's been initiatives around to bring more new blood in. A math PhD with an interest in optimization looks like a good fit.

There aren't so many employers (Cadence, Synopsys an Siemens/Mentor are the 3 bigs), but the domain is extremely technical with an history of pushing the envelope. SAT solving for example has progressed a lot thanks to EDA, and we not benefit from it in software with its SMT extension.
We’re not talking about sign-up pop-ups though. Those are an annoying fact of digital life that isn’t _really_ that bad.

We’re talking about creating a flow and perception that you can use a thing built around an assumption that you then intentionally change at some next step. It’s a breakdown of an implicit contract you create with the user, for the purposes of farming data, getting more signups, increasing conversions, or whatever else. It’s just dishonest.

A few years ago a family member contacted me about this very thing. They had found a nice looking website to accomplish a thing. The website had published pricing for packages of their service, and provided a “free” sample. Except after you spent all the time to get that free sample running, you couldn’t actually use it without paying.
