Interesting. I'll have to take your word on the necessity of hydroponics to meet quality at a price point year around because don't have enough detailed knowledge.

I currently live in southern New Mexico which I suppose is really northern Mexico if you removed the political lines. Yes, sun is not lacking here at all. The problem here is intense heat and scorching sun and wind and hard water. Crops like tomato and bell pepper do not really produce outside (fruit fails to set except for a couple months, bell-pepper the size of habanero if you are lucky enough to get one or two).

People have tried greenhouses but they are too hot. Some have tried with wetwalls but the hard water quickly ruins them. Several abandoned attempts (not to your scale obviously) sit around town as a warning to others.

I've been experimenting in this area for a few years and finally last year was able to grow a massive crop of tomatoes (that set fruit all summer) and full sized bell peppers. Even a rhubarb which the sun would fry normally.

I built a metal hoop house and covered it with 40% aluminet which is a reflective shade cloth, no doubt you are familiar. Normally I guess removing 40% of the light would be an issue but there is just _so_ _much_ _sun_ and my feeling is it probably compares to normal atmosphere and cloud cover in say, England but don't have any hard numbers.

I was really surprised how well it worked and what I was able to grow. I left it open to air circulation with no plastic. It cut the harsh winds down to a nice breeze. I did have an early problem with aphids in some crops (exactly right about the threat of pests in greenhouses and pseudo greenhouses like mine). Next year I'll be introducing lacewings and minute pirate bugs with wheast very early and hope to avoid as much soap spray and cursing.

I'm expanding the tunnel over the winter (got 3000 square feet aluminet but will only use maybe 600-800) and trying a number of different indeterminate tomato varieties on string with clips. Then lean and lower as they reach the top. Similar (but smaller and not as pro) to what you are doing.

My medium is 1/3 peat, 1/3 composted cotton burrs and mushroom compost and homemade compost, the rest sand and perlite with bone meal, blood meal, calmag and micros, traces of clay and some crushed volcanic stone. Also water holding crystals. Growing in 7 gallon bags. Fish emulsion and kelp compost blends primarily for fertilizer. All water is run through an osmosis system I built with an RV softener and undersink RO parts into a 300 gallon tank then pumped.

Open (or non enclosed with translucent cover) aluminet is a real game changer in this region and I've wondered if it could be commercially viable to expand the range of crops that could be grown locally. It also holds in some heat and I evaded the first 3 frosts still producing tomato and pepper. But for now am just puttering and experimenting and enjoying some really excellent tomato and peppers!

Thanks for the info anyway. This truly is such a fascinating topic and your plans and company are impressive.

Europeans especially. In my experience, they are extremely ignorant in this regard to the point of child-like naivety, but let them learn the hard way. It's truly the best way to learn after all.
That project won't improve things on that front.

Those robots need to be bought, then they need an operator and at least some maintenance.

You could probably hire 3+ cops for the price of one patrolling robot, or try to actually train those you have in sensible law enforcement.

There are better uses of the money basically everywhere.
I worked adjacent to the data science field when it was in its infancy. As in I remember people who are now household names in the field debating what it should be called.

At the time I considered going down that path, but decided I did not have anywhere near the statistics & math knowledge to get very far. So I stuck with the path I had been on. Over time I saw a lot of acquaintances jumping into the data science game. I couldn't figure out how they were learning this stuff so fast. At some point I realized that most of them knew less than I did when I decided I didn't know enough to even begin that journey.

Of course, I was comparing myself against the giants of the field and not the long tail of foot soldiers. But it made for a great example to me of how with just about everything there's a small handful of people who are the primary movers, and then everybody else.
Better still, do both. Power your Pi off of your laptop server to get the benefits of its built-in battery acting as a UPS for both devices.
That's because businesses don't require a deep level of math knowledge.
If it were actual (autonomous) robots, yes. The article is actually talking about ROVs (remote-operated vehicles). The city still needs to pay a human operator, who happens to be a moderate distance away.

It's arguably financially justified in the policing case because policing can be dangerous. Cleaning up [stuff] and sanitizing things isn't particularly dangerous, so you're basically just buying a robot to make your janitor less efficient.
I agree that posting the original link is probably more useful, but I find it very odd to call Bruce Schneier's blog "spam".
"The science" (I really hate that phrasing) doesn't change. Conclusive results require reproducibility. If "the science" changes then the initial findings were not reproducible and thus non conclusive and not "the science". Reproducibility points to a particular conclusion so following the trend shouldnt result in a complete 180 turnaround in provided information (the vaccines prevent the spread -> the vaccines don't prevent the spread). If they didn't have conclusive evidence of their statement they should just say " I don't know, but we are working to find that out". Premature assertions of correctness by the CDC, WHO, and other public health officials based on (now known) incorrect conclusions has done untold damage to their credibility making the public hesitant to trust them regarding any health guidance and in the worst case raising suspicion of malice from those most hurt by their guidance.
What would you expect from a digital nomad accommodation platform?
With the increasing popularity of some digital nomad destinations, the prices are skyrocketing. I started a free platform where people can buddy up to share bigger accommodations, so saving money and meet people.
What feature would you expect from a platform like this?
Yes, these robots are pretty slow and relatively difficult to deploy. It is extremely difficult to imagine a scenario where "loss of life to members of
the public or officers is imminent", but police still somehow have time to deploy and pilot this thing into a crime scene from a safe distance. If they had time to do that, then there wasn't really an imminent danger.

Realistically, this will be used when someone has barricaded themselves in a house or something and is having a standoff with police, and they've gotten tired of standing around outside and would rather send their robot in to shoot the person so they can go home.
It's amazing to me how seemingly mainstream this conspiracy theory has become in the US. People used to joke about "think of the children" being used to justify all sorts of ludicrous policies. Now you can just make up any baseless allegations about your political enemies and throw "child abuse" in to make it stick.
Well, there are plenty of approved drugs with tests and clinical trials that were later withdrawn from the market for being dangerous. What I'm saying is that the process is not infallible and in some cases it proved to be susceptible to corruption. We need to improve the process and that's not going to happen by blindly trusting Big Pharma.
If by ‘weird’ you mean teetering on the verge of lawlessness, then yes.
They used CBD, not THC.
I have been working with HTML since I was 11 — 20ish years. I thought I knew most things. text-decoration-thickness? Nope. I have been adding border-bottom to spans for far too long it looks like.
What does that mean though? The whole 'suspect is holding a hostage as a human shield so you shoot the suspect before they kill the hostage' is a fun trope for TV and movies, but that's not how things work in real life.

Also, criminals will know the robots have these capabilities, too. If a barricaded suspect hears or sees a robot rummaging around, that could be interpreted as force escalation. Which may cause the criminal to react in unpredictable ways that increase risk to the public and police officers.
> Approaches that are wrong from a statistics point of view are more likely to generate impressive seeming results.

This is to be expected from an information theory point of view. It's why "fake news" will always be a thing.
That is great, and those studies are very promising, but I think you are being flippant when you say "which even the proponents of ivermectin claimed wouldn't work". In my understanding. the majority of 'proponents of ivermectin' were politicized and had no conception of prophylactic use -- the major harm caused by the ivermectin narrative was a large population refusing to vaccinated and then relying on ivermectin when they became infected.

If you could could point to evidence that those pushing ivermectin during the height of the pandemic and the hospital crush were advocating low/moderate prophylactic use I would be grateful.

"Last decade" is too generous.

HFCS wasn't last decade. Trans-fats wasn't last decade. We've known they were bad more than a decade ago.

Many more decades ago they marketed these artificial food alternatives without any evidence of long term health effects, and the process of "proving" them bad took many years (funny how the onus lies on the potential victims), and only recently we've been able to mostly contain the damage of HFCS and trans fats.

It seems every once a while this process restarts again. Americans sure love to play with their food. (I'm not American)

I found the summary useful. I read the whole Guardian article and Bruce highlighted the really interesting part. The only other question was: what's in the letter?

The answer is pretty boring, just a standard communique between two leaders during a conflict and talk about a previously unknown murder plot (which was just a rumour). The meat is the cipher.
I know it's an anecdote, and I'm the founder of the Snikket project, but I rolled out an early version to 10+ family members during lockdown. The majority of them were remote and ages from <5 to >80. I emailed them the invitation link, and that was about it. They all managed to sign up with no issues.

Scanning a QR isn't actually necessary. That flow exists for when you open the invitation on e.g. a desktop or laptop, and you actually want to set up Snikket on your phone/tablet. The invitation page guides you through you what to do in that case, you don't need to know what a "QR code" is. But most people just open the invitation directly on their phone, and it has a magic link to install the app.

In some ways it's easier, because you don't need to go through the SMS verification and stuff that the phone-number-based platforms require. I know various APIs and hacks have made that flow easier over the years, but it's still an extra step for non-technical people to get lost in. It's also an obstacle for people who want to use a tablet, such as my children who are too young for phones.

In any case, I'd encourage people to be less defeatist about the adoption of more open alternatives (intended or not, that's how I read your comment). It is possible... my own family average no more or less technical than any other. They manage to use WhatsApp without help, and they manage to use Snikket without help. And of course I'm not the only person using it successfully.
I was only cynical about the urge to irritate people with a request to register to receive worthless updates (if one really wants to harvest many email addresses for hostile purposes, there is better bait than niche software).

My impression, based on the OP's introductory comment in this thread, is that development of this product is earnest but severely unfinished/half-baked, with a somewhat annoying but "normal" marketing style and business plan.

Unfortunately, a new app/startup of this sort is not judged by backstage discussions on Hacker News, but by their website, and the first impression of the website is shockingly terrible: nothing to read, nothing to see, and a prominent request for our email addresses that adds up to negative value.
I suppose the other thing to consider is the (art book in the photos) by an author who regularly depicts children naked, dismembered, and covered in blood.

Please stop engineering doubt. It's absurd to pretend that there isn't a consistent theme of child abuse here.

Not a claim on OP, but in general for this conversation: I find it intriguing that the level of grace and benefit that is given to the people involved in this controversy seems to be at an all time high. I wonder if the same people extending this grace and benefit of the doubt would do so with those opposed to them politically.

The BBC has an article that explains:

> I don’t understand what you mean by JSON was not invented. It was invented by Douglas Crockford.

Douglas Crockford took his time to write up a specification for the JavaScript Object Notation (JSON).

That specification is, quite literally, "based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999."

It's in the name. There is no way around this.

MDN's doc on JavaScript's eval() vs JSON.parse() refer to JSON as "a subset of JavaScript syntax to represent data."

Claiming that someone discovered JSON makes as much sense as reading the C standard section on struct initialization and proceed to claim you discovered the C struct notation (CSN).

I love that eglot is being incorporated into emacs, though I myself use lsp-mode. Does anybody know how advanced eglot is? As far as I hear, it doesn't support multiple language servers which seems like a showstopper for web dev these days, e.g. I usually have ts lang server + tailwind lang server running at the same time when doing web dev.
The grid runs on averages.. If all 15 houses connected to that transformer were drawing 1kw for lighting, and it was spec'ed to allow for 2kw each, there are 15kw available for peak loads as people blow dry their hair or run their AC. It's not saying that houses are limited to 2kw, just that the system was designed for them to average 2kw.

The article gets this right and it's a completely normal part of utility design and distribution, which is unsurprising because the person quoted is a PE-licensed electrical engineer with the title "Director of Utilities".
Rolling your own crypto is bad, unless you’re an authority on crypto. Moxy certainly is. Also, Signal Protocol isn’t an encryption algorithm. As far as I know, it still uses AES and Curve25519 for the actual encryption.
1. Fact: The reality of most ML modeling on data is a lot of models don't need to be giant ass interaction machines with 10^80 features. Many non linear models with a Naive Bayes or other simple non parametric models and adding a few Boolean Random Indicator Variables to your regression will go a long way to make your models non linear and get you to 80% F1 score. These are all practical problems and none of them require just a pure DS but also ML skills

2. Fact: You need to deal with bigger problems in ML like data set class imbalance, calibrating responses to the right scalar range(figuring out what that range even is in terms of domain). This is not taught in schools, just like writing Software is not taught in schools. One needs to be in the field to learn these skills and an ML Engineer can pick these up as much as a DS.
"Science" does not have any ideas about anything. Science is a tool that humans use to learn about the world; it is the human beings who have ideas about things. And, because human beings are fallible, it's generally advisable not to give a small group of them absolute unnacountable power over the speech of everyone else. "If men were angels" and all that
The 68030 was a 68020 leaving out a couple of rarely used instructions (I don't recall what) and adding a sort-of-but-not-exact subset of the 68851 MMU, 256 byte cache and some bus interface improvements (sync access). That and process improvements made it more efficient than the 68020. Motorola also upped the clock speeds on the 68030 (up to 50MHz).

The EC chips, at least at the beginning, had a defective MMU that was disabled and sold cheaper than a 'full' chip. Fine for the Amiga OS, or embedded stuff. I don't know if they ever made them without the MMU at all. The EC nomenclature extended to the 68040 and 68060, where it meant "no MMU or FPU", and added the LC nomenclature which means "MMU, but no FPU".

Ask HN: How innovative is the hydrogen industry?
Sure it might seem as an odd question. But looking at renewable energy sector as a whole, how far is the hydrogen compared to others?

Any noticeable innovations?
Any large difficulties?

I am curious since a client has approached me in this space and know very little of hydrogen innovation.

Thank you

they lied because they thought there would be a mask shortage, and medical workers needed all the masks they could get. So they told people they dont need masks.
Isn’t wanting “enough money to not have to work” similar to wanting your body to not need oxygen or food or sleep? Sure, it would be amazing in many ways, but perhaps a tad unrealistic? I guess the problem is that we see some people who are in that position with respect to money and it makes us jealous? But we can choose whether to feel gratitude for what we have or feel jealousy for what we don’t have, and it’s probably obvious which course is healthier IMO
I think the issue here is that "data science" encompasses two very distinct branches of work. One answers to business needs and the other produces data based solutions for the product itself i.e you might have a data scientist who A/B tests your website design so you minimize your churn rate and the other is the team at uber eats who maintains the recommendation engine. While the distinction might not always be as sharp, the former makes up the bulk of data scientists in the market (and I suspect the OP is in that boat) with comparably simple interviews while the rest is the 5 step interview process with hackerrank test you are more familiar with.

Not for newcomers to the codebase. Approaching an application that is forced to make the entire application clear as day (as in Go) is so much easier than such Java codebases because I can just read the code and see what it does. This is just my experience though. The Java codebases are always fine as long as I have read several pages of documentation first, which I've learned to do for those cases.

How do you distinguish what is "layout" versus "style"?

I know there are some obvious things, but like you said CSS is used for both. So there is a lot "grey area". Especially when "style" can affect the "layout".

As a Brazilian living in a Nordic country and working in a different Nordic country, I can corroborate that the expectation from the locals here is that everything in planned in advance (with plenty of notice: 1 week or more); I can also corroborate that Brazilians in general do things spontaneously.
Here's a half hearted attempt... this is actually a good thing, because then there will be less people on the planet and less garbage, pollution, destruction of ecosystems, and everyone will be richer.

Presumably, few people will try to unleash drones on nature, and even if they do, they will only have minimal effect given the enormity of the planet. On the other hand, currently we have factory farming where billions of animals are brought up in abysmal conditions to feed the population meat, they live on an ecological credit card, and it's probably far more destructive in the end through famines or just general ecosystem collapse.

Seeing what's coming from that, you might actually consider the threat nuclear war to be comforting...?
Interesting Q&A, thanks for sharing!
Someone can fact check me, I'm going off memory: I believe in v1 Tailwind (before they added the "JIT" compilation) when you were in dev mode it just had all the classes available at all times, and then added a step to the prod build where it would purge unused classes from the CSS.

Now Tailwind scans for which classes are used as you add them and builds an output from that. So if you only used `m-auto` the only CSS it would output in the final build is

.m-auto {
margin: auto;
}
