While a good read, I'm not sure how anyone can take this seriously. He says " Efficiency gains from the electrification of industrial processes would vary widely, and not all of them could be electrified. And there will be negligible gains for space heating , with 100% efficiency for electric resistance heating compared to as much as 93-99% for modern gas furnaces (Lennox 2023)."

Heat pumps have a COP of 1.5 - 4, which are eventually going to replace all heating/cooling. He does not consider efficiency from heat pumps at all.

Electrification is efficient and the transition won't need as much:

But felony murder is still usually reserved for circumstances where the original crime is violent itself. You may be guilty of felony murder if the bank guard shoots one of your fellow robbers... you were committing violence after all. But when criminal negligence is the extent of your original crime, homicide should be limited to, at most I should think, some manslaughter charge.
Depends on how you quantify rugged or durable. It certainly seems far more resilient to dings/dents/scrapes, which the average car is definitely not resilient to currently. Whether it handles rusting/environmental conditions well seems TBD at this point. Probably worse for “looking nice” after a wash than the average car, but these things are so damn new I don’t want to pass judgment yet.
You handle it with redundancy. Four smaller motors instead of a single big one, and so on.
Last I knew, my intern mentor at MS claims to have never sold a share since he started in the mid-90s. I haven't talked to him in a while but if he really did keep stacking up MSFT for 30 years he'd be easily worth $62M. I don't think this is a sound investment strategy but glad it worked out for him.
Yes, you can set the min/max for scale. I scale down to “.25” as my min.
> So while I agree that creating what looks like arbitrary limitations some of the lower models is very annoying ( particularly around external monitor support [1] ) - you can see why commercially they might have done so.

This is Apple's strategy for segmenting their products. Their lower priced models typically have a painful limitation or missing feature. For the macbook air it's lack of support for external displays.

These aren’t quite the same thing. Sensitive ground fault protection attempts to shut down the line more quickly in the event of a ground fault. A ground fault neutralizer attempts (and apparently largely succeeds!) at reducing the fault current to near zero during a fault even before anything is shut down.

These technologies can be combined.
Upscaling algorithms vary from the extremely basic to the ML models we see today that straight up replaces or adds new details. Some of the more naive algorithms do indeed just look blurry.

Planes have spent nearly 100 years moving from the "cowboy" era with brave "men" risking their lives to the modern era where planes are one of the safest ways to get around. They did they by analyzing every accident and near miss and figuring out how to ensure that doesn't happen again. Car owners resit the idea that they are not perfect even while they do things like use the phone while driving, drink alcohol just before driving tailgate, speed, stop in the crosswalk, and so on. Those are the things that either have been taught in driving ed for decades, or have had large media pushes to raise awareness. Don't get me started counterintuitive on things like the zipper merge which most people think I'm the bad driver for doing. I'll admit that the above is a list of things I know about and attempt to do - I have no idea what else I might be missing.

We now have the technology to have very realistic driving simulators. (I've seen what they give snow plow drivers) We should require drivers spend several days per year in a simulator to make sure that they can do things right in the weird situations. Pilots rarely fly in the worst weather (they will fly above, around or stay on the ground - though they will fly through what looks like bad but isn't - I don't know how to tell the difference), but they get lots of simulator time in the worst case situations.

“Slaves built the US” is a silly idea.

I hate how you get racial with your comment, but since you want to go there: literally 90% or more of America from the 1700s through the 1900s was physically built by on the backs of Protestant white labor.

Your view seems to be narrowed to a few isolated railroads or tunnels built by the Chinese or Irish near the coasts. You’re forgetting the development of the entire vast interior of the United States.

Hundreds of thousands of miles of roads carved and built from nothing. Fields cleared and plowed. Irrigation and drainage ditches. Towns and cities along with their infrastructure built up out of the dirt, essentially none of it done with slaves or indentured labor.
I'm curious what makes you consider it non-ergonomic? For the things both support, I don't remember that many differences. Org shines, though, for all of the other things it also supports. In a real sense, it is more in the same realm as jupyter than it is markdown.
Because as companies get bigger they worry more and more about the long tail of risk.

They do this for many reasons, but generally predicting the risk of very low probability events is very difficult, so they don’t understand the risk vs cost tradeoff as well as they think.

Given AWS charges extra for IPv4 these days and is IPv6 by default, either it's an old memo or not AWS.
If a human spends the first 30 years of their life in a cult they will be also speaking nonsense a lot - from our point of view.

Sure, we have a nice inner loop, we do some pruning, picking and choosing, updating, weighting things based on emotions, goals, etc.

Who knows how complicated those things will prove to model/implement...
practically nothing in this country for the past two centuries was actually built by the white European protestants

Gonna strongly disagree with you there. Look, many people don't like it, but the truth is that many of those myths you just proffered are only half true. Many Chinese participated in building railroads, but so did many, many white protestants. And guess who designed the rail roads and surveyed the routes. Also, not to put too fine a point on it, but the entire system was kicked off through the labor of blacks who built the rail system in the east long before many of either the Chinese or the poor white protestants even got here. And did most of the dirty work to extend it west so that the Chinese you're talking about could connect it.

Canals, again, were definitely designed and organized by white protestants. And, also again, blacks did the majority of the early work there too. Why? Because everyone else, from the native americans we tried, to the Irish, tended to die from malarial disease doing that work. Horrible as it sounds to say, it's more accurate to say that many Irish, um, "made sure blacks were working hard to build the canals". But to write white protestants out of that story? When they literally conceived and designed the whole thing? Nonsense.

And on and on. I mean really? Italians built New York? Where do you think the harbor came from that the Italian immigrants sailed into? The infrastructure fairy? Where do you think the engineers who conceived those bridges, harbors, ports, Ellis Island, etc etc came from? Out of the butt of a rainbow colored skittles pooping unicorn? It was white protestants. (I'll make you even madder, most of them were male.) Oh, by the way, guess who the protestants had doing the work in the caissons? It wasn't Italians. Slavery was horrible. Especially for blacks. But it got $#!t done.

You can believe your origin myths if you like, but please, don't try to make your space in America by attempting to write other people out of theirs.
> A DC breaker has a chance of arcing and it may be necessary to make them larger, or use exotic gasses with high dielectric values to prevent this from occurring.

That's a problem for mechanical switches (were conductors move to make contact or disconnect).

If you use semiconductors to do the switching, it becomes a problem of how fast they switch, how much energy is dissipated during the switch, and how much energy those semiconductors can absorb momentarily (thermal mass).

For small equipment, this is a solved problem. Fast switching FETs are cheap & robust.

For utility-scale, semiconductors are an entirely different ballgame. Big advances have been made over the last decades.

So a HVDC grid might in theory be possible. But in practice, it'll be an engineering tradeoff between HVDC+semiconductors almost everywhere vs. HVAC+more traditional gear like transformers.

And even if a HVDC grid were practical with modern tech, in most places there's existing AC-based grid & power plants. I suspect the "sync AC phases" is an easier problem to solve than "re-do the grid to use HVDC".

But for 'simple' point-to-point connections like an offshore windpark or long international lines, HVDC is sometimes practical (and used, if so).

One. And the question is are they here. There have been flying car attempts for many years that have resulted in working prototypes. They aren’t here. They’re just over the horizon along with self-driving cars, cold fusion and commercial airships.

There are significantly more drivers than pilots and are much less regulated - i.e. capability. More interactions in driving then airplanes - more traffic. Much higher probability of collision or issues. Flying has more complexity for the most part but also has a high degree of automation.
>You can't totally reject some of these diagnoses, regardless of how porous the boundaries, without depriving a lot of people of the care they need.

Which is precisely why the DSM is a political document, designed for clinical utility, and not a scientific one.

I will mention that several of the barriers to create we create to care are artificial. One of the most common fears I've heard from those with ADHD is that without their diagnosis being taken seriously they will lose access to their medication. Yet that's only an issue because we won't give people drugs, even if they find them helpful, unless prescribing physicians believes they are disordered. Consequently, there are ADHD communities who ban people diagnosed with ADHD for having too positive of a self-outlook.

The entire system is deeply twisted. We've made acceptance of an intrinsically derogatory pseudoscientific nosology a gatekeeper, and put reflexively categorising patients as disordered at the centre of our care model.

I switched my company over to Neon from PlanetScale. In part for the ability to scale up/down easily and also so I could run multiple databases on the same cluster.

I also looked at (and spun up) RDS but Neon was way easier to work with and scales to 0 (Aurora Serverless is trash IMHO). Neon starts very quickly as well (hundreds of milliseconds in my testing) which is pretty awesome.

I'd advise not worrying about the benefits others see to either, if you are wanting to meld them. Instead, meld the parts that you like above and beyond anything else.

My reasoning is that the main advantage of Markdown is the crowd using it. It is not an unknown quantity to a lot of folks. Similarly, the biggest "pro" of org-mode is that it has all of the power of emacs. Which, is oddly its biggest con to the crowd that doesn't like it.

Kinda funny that the commit message doesn't say anything like "remove hell mode", it's integrated into another unrelated patch
They're likely continuing manufacturing for everything except for the part of the line where the interior drive controls are assembled, depending on how much stockpile space they have (which should be a lot with how big GF Texas is). If they already have a fix that they is just a modification they would continue full line manufacturing then stage the completed vehicles for when the modification is ready.

Chances are they _really_ want to make a fix that can be done at service centers, so that they don't need to ship all the CT awaiting delivery back to the factory for the fix.
You're not wrong, but it's rare that people believe their judgement is clouded, in fact, they likely feel their judgement is highly informed by what they view as stupidity or genius.
Because almost 100% of the time that is the only way that you can get legitimate 4K ultra high definition high dynamic range content over streaming services. They won't give it to you over your web browser on your PC. Doesn't matter what operating system you run. It's got to be a set top box or a smart TV.
Look, you can bloviate about how "easy and not complicated" IPv6 is and how NAT is a cludge... but failing adoption and horrid bugginess of IPv6 network stack implementation is showing the actual truth of just how much IPv6 changes and complexity hamstring the standard.

The fact that you consider SLAAC somehow equivalent to DHCP shows that - I've never seen a router (outside maybe some ciscos) where those two could be used to achieve the same stable network assignment and configure downstream service firewalls appropriately. That is - if SLAAC actually works across all clients and they're not a buggy mess.
To provide more context, our original plan was to launch the GA on March 22nd. However, we decided to move the date to April 15th because a few projects required additional time to complete. Last week we saw Supabase announcement but we didn't know what is that about and decided to not to move our date again.

I fear this is a psychological issue: plane crashes involve many fatalities in one single event. People take notice and are scared.

But, people don’t care so much about a “small” car or even a “small” plane crash. Even if they add up to an insane number as high as 40k per year!

Google themselves have tried to build several new revolutions throughout the years. Wave and Inbox are the ones I can easily remember. Workspaces probably should also count?
The steps are Embrace, Extend, Extinguish.

Embrace is the one you can fork.

Extend is the closed-source bits that connect to the open source stuff.

(For example, all the closed-source extensions to VSCode.)
Only for people who have no skin in the game. The actual network operators are redeploying NAT even on IPv6 installations which tells you a lot about how disconnected from reality the IPv6 folks are.

(But that was even shown when they were dreaming of deploying IPv6 without any kind of DHCP which had to be backtracked making a utter frigging mess of address assignment on networks with multiple competing approaches.)
It's ironic. In 90s U.S. purposefully sabotaged Japanese chip industry with tariffs and other coercive measures. Today, a Japanese company buys out a poster-child of American industrial capacity.
I'm working with a client on a greenfield project and I picked postgres as the tech stack. For the staging server, I just locally installed postgres, configured it, and it works perfectly fine. On the flip side, I'd rather just focus on code, and if there's a free tier (which neon has), I'd rather shell that off to a service.

So, my question is, what trade offs am I making other than a persistant/local db to off-site (ie probably a degree of speed). Since it's free, does that mean my data might be inspected? I'm under an NDA, and my client would prefer his data stays in-house unless there's a good reason for it not to be.

Ask HN: Best way to avoid media and tech news and staying relevant?
Reflecting on a vacation right now and wondering best ways to avoid mainstream tech news/social media and still stay relevant.

Moreso interested in people who have these ideologies, but still succeed in staying competitive and knowledgeable in new trends/science. Competitive being raw knowledge in necessary topics in the field and not competitive in the sense that you grinded leetcode for a job.

Social media wise, I’m referring to avoiding news sites focused on technology/things that require my attention on a screen.

Overall goal: reduce screen time. And no, I don’t have a smartphone.
> Security is job zero.

This is really vague point. What's security? You can spend millenia securing anything without clear target. ssh with root:toor is probably not secure. What about ssh with 12-chars password? Shall we disable passwords altogether? Shall we change port? Shall we implement port knocking? Shall we investigate ssh source code, recompile it, remove anything not needed in this particular server? Shall we rewrite ssh from the scratch using Rust? Shall we build new language with better security focus?
TY, fixed. Neon does have a public Discord https://discord.gg/92vNTzKDGp

Agreed. From NTSB's website[0]: "In cases of suspected criminal activity, other agencies may participate in the investigation. We do not investigate criminal activity. Our focus is solely on transportation safety and determining probable cause. If a transportation tragedy is determined to be a criminal act, local law enforcement or the FBI becomes the lead investigative body."

The FBI opening a case does not guarantee that someone will be charged with a crime per se, but the timing of this announcement coming weeks after the collapse, not hours or days after, suggests its not simply a procedural matter. Rather that something was found and given to the FBI to investigate further.

I'm not sure there are any serious people who would contend that. They may be seen as a pariah of sorts due to many of their policies but no one doubts their economic and military prowess.
Like super profitable businesses stopped squeezing for more money?
Every shit business person will try to get a promotion and buy a new expensive car and yacht and the only way to do that is make even more profit, so most of the time the quality of the product or service goes down.

There might be a correlation with the economy, where they need to triple down on the enshitification but it could be cultural, "the other managers did this shit and they bought soem cool sports car, I am better then them I will buy 2 cars"

Citation needed. Especially for the "generations". From your own example, you seem pretty well-integrated into mainstream American culture only one generation down.

My personal thesis is that some countries are really good at absorbing and integrating immigrants, and they see the benefits. America is exceptional at it, possibly the best in the world.
good point - yeah D1 i think is sqlite based. for my toy projects that hasnt mattered so far but for more complex projects i see how this is a big difference, thanks for pointing out!
Yeah, all of these sound like goals that engineering should work towards, basically anywhere. You can reword them into modest principles.

1. Simplify requirements.

2. Reduce widget usage and determine limits.

3. Omit work where possible.

4. Time is of the essence.

5. Remove manual labor.
