I suspect you're getting ion propulsion confused with nuclear fusion. In order for deuterium and tritium to be useful for fusion, you're going to need kilograms of it, not individual atoms. And tritium is required to be radioactive for it to be useful for fusion, but it has a halflife of about 12 years, meaning any fuel we take with us will be useless pretty quickly. And that's even before you take into account the idea of "constant acceleration"... some sort of magical sustained explosive reaction that would go on for 100 years? And that's after sourcing the unobtanium required to shield/support the "constant" detonation.

I suspect you're thinking of an ion drive, which uses fancy magnets to accelerate mass (pea-sized pellets all the way down to individual molecules), which is a slow start but is fine for constant acceleration over tens or thousands of years.

The problem there though is that the acceleration is SLOW, much less than 1G, hence the 20-80-thousand-year estimate to get to our closest star.

>If you go to 1920s and ask a million people if humanity will be able to walk on the moon within their lifetimes, not a single one would say yes.

I'm not sure I agree with that. Spaceflight and lunar (and even Martian!) colonisation was a pretty common scifi idea by 1920. Cars and planes were already 20 years old by that point. If you asked a million people in 1920 I'm pretty confident you'd get a decent chunk of people saying "yes".
> The culprit? They downloaded the OS image using FTP and forgot to set binary mode. Various other network kit vendors I recall would do some level of validation (and anyone downloading should be checking the hash). RCA sent to customers was vague and just said it was a corrupted image / failed upgrades.

I've always been paranoid about this sort of thing when applying BIOS or firmware updates, despite those almost always having checksum validation, but I guess my caution is not unwarranted.
is this identical to "fake it till you make it"? so you climbe too high on carier lader and it's scary up there but you also dont want to climb down, ao you expect someone to come help you stay there. dont take this personally, but such cases make me angry, because most of the time it prevents competent but quieter people to rise, and pushes them away from competent deciasion making.

Drain heat recovery is quite common here in Canada and mandatory in a few jurisdictions for new builds.

As for the hot humid bathroom air, that also exists in the form of ERV (energy recovery ventilators). For well sealed houses you route all the exhaust and intake for the home to one place where there is a heat exchanger to minimize the losses from getting fresh air into the house.
Sorry, no tritium.
This was the case against raising interest rates in the EU. It’d affect the servicing of the debt for countries like Italy.

Companies are screwed. Big companies might get bail out, or not. Governments, especially big ones like Italy, will probably get a bail out and break the stupid system once and for all.

It’s not that the system does not work, but it’s getting abused left and right by people who think they know shit about economics.
The idea is you `fmt.Errorf("invalid foo, given '%v' important argument: %w", arg, err)` and you end up with errors like:

http GET /abc: start DB: run migration COOL_MIGRATION: invalid foo, given 'bar' important argument: file not exist

If done well, you might be able to fully diagnose the bug just by reading the error, since it may include every bit of relevant context. If not, you can grep for the original error substrings to find the relevant code.

The point is that these aren't just Xs on a map telling you where something went wrong, they're supposed to be meaningful descriptions of why something went wrong.
I think something similar happened to tech startups, in between the 1990's and 2020's: https://app.pressnt.net/post/77/ (but I had been blaming interest rates, not saturation — I guess if rates continue to return to normal, we'll get a chance to see how much of each factor was important, by whether or not hit-driven software development returns)
Yet another example where mass production replaces craftsmen. Why try to find brilliant people to make something new when you can just churn out another super hero movie?

I think the situation with interstellar travel is well summed up in this conversation between TARS and Cooper as they attempt to dock at Endurance (intentional pun hiding in movie title):

TARS: It's not possible.

Cooper: No, it's necessary.

It seems impossible, but if we don't pull it off we die. And I don't mean we the few folks on HN. I mean everyone.

Earth is a graveyard of species. Nearly all (99% IIRC) species that ever existed have gone extinct (most before we showed up). As a species, we can't stay here and live. A 9-mile thin layer of gas over a single small planet is just not a reliable long-term basis of survival. In fact, the fragility of our tiny little habitant is on display right in front of us this century.
Makes a big difference in quality in my experience and the conversions generally run overnight. Same applies to M1 architecture and high end gaming PCs.

Aspire has blown me away with the end result and speed of computation.

This sounds similar to Boeing's reasoning for not documenting the MCAS system on the 737 MAX.
Earlier today another HN user linked to a PDF from a previous 2018 (cira 2014) investigation that pointed to the "dual-channel back up" system being fragile and likely insufficient.

https://news.ycombinator.com/item?id=34338373

> ERAM’s original design did not include a dedicated backup system. FAA believed that ERAM did not need one due to the redundancy provided by the system’s dual channel design. This design was intended to prevent outages because it allows for seamless switching between the two channels without impacting air traffic control should a problem occur in the active channel. The Agency believed this redundancy would make it unlikely that a problem in one channel could migrate to the other channel. In addition, to provide additional backup capabilities during ERAM’s implementation, FAA planned to temporarily maintain EBUS, its pre-existing backup system, before phasing it out completely beginning in 2015, to rely solely on ERAM’s dual channels.

> However, problems experienced during and since ERAM’s implementation have shown that the system remains susceptible to dual channel failures. As a result, FAA decided to maintain EBUS much longer than intended because air traffic controllers currently rely on EBUS for backup. However, with FAA’s ongoing and planned upgrades to ERAM, which will span the next 7 years, EBUS will soon become incompatible with the new hardware. As such, FAA plans to begin phasing out EBUS in April 2019, leaving ERAM without a backup system to supplement the system’s redundant dual channels.

A $2 billion dollar Lockheed Martin system where a memory overflow takes down BOTH the main system and the backup system. Surely that's not a signal of fragility.

There are also lock free algorithms written in Assembly, that doesn't mean the authors had any fun writing them.

More like a "law". Law of the Jungle.
Based on other comments, this has been done for psql, or at least to some extent. So that's the other thing... pre-emptively writing code in a non-intuitive way for performance reasons often leads to practices sticking around long past the rationale for them even being true.

It's organic political opinion. For one thing, Germans feel very real guilt for their invasion of Russia in WW2, and they don't like the idea of aiding in a war against it. For another, the experience of the Cold War was much more traumatic for them than it was for the US, and they're not eager to start a new one.
It costs Amtrak over $300k a year to maintain a single mile of track on the Northeast corridor. For comparison, it costs around $30k to maintain a single mile of US interstate, i.e. only 10% of the cost to maintain rail track. In what sense rail is cheaper to maintain, exactly?

Also, I agree that the idea for interstellar travel has some holes. Let me rephrase my argument as follows : for every accomplishment of mankind (airplanes, spaceflight, moon landing, nuclear, computers, internet), there have been just as many critics claiming that it isn't possible (they had their own set of reasons). And all of these technologies were much more infeasible compared to interstellar travel (and yet we did that).

5 years ago, would you have imagined ChatGPT or Stable Diffusion? Tech moves fast. There is no doubt in my mind that in a century, we will see interstellar travel like we do airplanes today. But this may well be wishful thinking because I really want this to be true.
Canada and the UK illustrate the downside of single provider, but the US has embraced all of the bad about single provider, but with multiple providers. Anyone can get into the game, but no one tries to make the product better. The patient is not the customer in either the US or Canada or the UK. They are the same in that respect and that is what matters.

This is an unnecessarily cynical comment, IMO. The title already establishes the value prop of the project as a "Show" entry; it's an action RPG, i.e. game. It's not "I made a clone of a C tool but in Rust" where there is no actual value prop.

It's a bonus that it's written in something a bit more interesting than your average game.
> no one is going outside with this shit.

Plenty of people would though if it would work well. It doesn't though. And sticking your phone in front of something really isn't going to work imho. But I would definitely wear them outside as interim solution, not the entire day, but normally I walk to places (4-10 km/day) and a lot of that is boring and spent thinking of on my phone or both. I would wear them there.

The TCL RayNeo X2 looks pretty ok, however, i'm not sure what it really does. It says it will send out to devs soon, so it means there are apps and the reviews during CES don't look bad, but there is no pricing, specs etc. At least not that I could find.
> Yes, because I believe all so-called creative fields will be dominated by AI in the near future. Programming jobs will mostly be replaced with jobs writing prompts for the AIs that write the code, stories, make the art, music, etc.

I'm not convinced of that. Mostly in that for every "easy" tool to do things like make forms for input, store data and print reports... there has always been a limit to where you need an actual developer/programmer to do more. And in many cases, it's more work to customize the tooling than if it was written in a more programmer friendly environment to begin with.
What is bad about it? An example would help me understand you better.
> glibc can assume that the timezone is going to be fixed for the duration of the process's life.

From what I'm seeing.. it doesn't seem to actually assume that. It does check to see if the TZ name changed between calls and will reload a new tzfile if it has. This same mechanism is what causes the file to be loaded whenever getenv("TZ") returns NULL.
> Yes, they can breed their own fuel but the total cost of doing it is wildly prohibitive.

You're being too generous. It's could theoretically not can. An actually closed fuel loop has never happened.
It will be interesting to see if most of the problems with FSD go away as soon as all cars have FSD as well as transmitters to signal to nearby cars what they are doing.

At that point humans will theoretically be the weakest link, and anyone driving "manually" will be a liability because they will lack the information and reflexes to deal with whatever is happening around them in a timely manner.
> Mozilla gave us Rust

Sorry for the nit but Mozilla didn’t give us Rust. They sponsored some of its development but that was only 3ish years after Rust started.
Yeah but they can do that a bunch of different ways and to me, it’s a sign to jump ship
> There is no reason the driver needs to be aware of it.

If the person operating the vehicle doesn't need to be aware of the difference, then the general public shouldn't need to either when analyzing an accident.

It seems baffling to me that we could imagine a scenario where it's less important for the driver of a vehicle to be aware of the difference, than it is for the public when reacting to a news article.

I don't think you get to have your cake and eat it. Either there is no relevant distinction, in which case the "well actually" response that "it's not FSD" seems unnecessary, or the distinction is important, in which case it seems problematic that drivers would be confused about it.
You cannot simultaneously support a welfare state and open borders.

Every non-payer added to the system lowers the quality for the existing members.
Four distinct points of light would generally appear when the driver has their fog lamps on. These are different from high beams. In fact, a lot of drivers where I live tend to leave both on!
tbh I never really understood that conversation. TARS is a machine and if it's impossible from an advanced machine's standpoint, it's impossible from a physics standpoint. Cooper's maneuver was pretty simple that TARS should have been able to simulate and figure out.

Regardless, I agree that being multi-planetary is absolutely a requirement for humanity. We are too risky here. And the risk is not from outside. Humanity has survived for 100s of millions of years without as asteroid annihilating us, and I don't see it changing now).

The biggest risk to humanity is humanity. We will probably figure out a way to destroy ourselves, either with something much more powerful than nuclear bombs or some new unimaginable tech.
First moving to a cooler light (white/blue) and second Xenon lights are now a trend. These tend to be strong and also you should do multiple of them so you look cool.

Yeah, car manufacturers are prefering look to safety now.
No, I'm not misunderstanding. I talk with traffic engineers on a regular basis on how the MUTCD is a large barrier towards safer streets. Pavement markings, including lane widths, bike lanes, counter flow bike lanes, HAWK signals, transit lanes and crosswalks affect the street design.

My largest personal pet peeves with the MTUCD is the requirement for far side signal heads. Far side signal heads cause crosswalk encroachment. If signals were near side only like in EU, crosswalk encroachment would be impossible because you lose sight of the signal head.

Every time this topic comes up somebody suggests constant acceleration, and every time somebody has to point out that even if you don’t want to decelerate the relativistic rocket equation is still a very harsh mistress. Remember you don’t just have to carry the fuel to accelerate your payload, you have to accelerate the fuel as well.

You may say, “Oh, but I could use a laser to accelerate my craft, that way I don’t need to carry the fuel on board,” and the amount of energy required is still going to be a hell of a lot more than you think.
And if someone doubts this, remember the Mirai botnet.
At one point I knew a lot about this. I vaguely remember, from old law school classes, that C Corp. makes it easy to create shares and invite more investors in. Further, it shields the shareholders from direct liability from many miss-deeds of the corporation, so long as the corporate meetings were systematically held, and decision making done per the shares held (usu. for electing board members).

Downside, is that taxes are trickier, as theoretically, the corporation is taxed once on profits, and the shareholder is taxed again on making gains/dividends. FYI, this is not legal advise, and I'm quite likely wrong on a point or two.
That's just silly.

Obviously it was due to details being entered using the now standard International foot when the software expected the now obsolete US survey foot [1] .. the discrepency across a transcontinental flight was large enough for a pilot to fall through.

What is your preference based on?
Because it’s a large open source project and it’s important to have interoperability with the rest of the platform.
There’s one thing about interstellar travel you should bear in mind. If you plan on visiting an alien world you should take into consideration the time needed to decelerate. And once you start decelerating, time dilation will gradually stop and you’ll spend an eternity getting to your destination.
What's your definition of "diversity" here?
Thanks! There is a lot the software world could learn from permaculture. I think software in many ways is more akin to gardening than building physical buildings.

Correct, that is the way.

> scalar instructions can easily introduce performance issues because they leave the high bits of the registers untouched (i.e., introduce useless partial dependencies)

How's that? SSE scalar ops are all two-address, so they depend on the destination regardless. And AVX scalar ops are three-address, but zero the high bits of the register. Where you run into trouble is mixing sse with avx, as you can end up in the dirty high half state; but that can happen with vector or scalar ops.
