Sunpower. Here's a list of panels sorted by efficiency: (just one I've been using while researching for a project)

https://www.energysage.com/solar-panels/?noidx=true&sort_by=...

I think they're the only on-the-market 22% efficient panel. This bloomberg article talking about 700W panels is inane, they just increased the panel size past the standard commercial 1mx2m.
My memory might be falling me, but wasn't Elon Musk's manipulation actually timed to coincide with his performance bonus, and directly ended with millions of dollars leaving Tesla coffers and endint up in Elon's pocket?
The grooves could have served some functional purpose as a tool. Could it have been attached to a cord and used as a sling? Some tools are used to create other tools, so it could be additionally difficult to speculate as to its purpose.
Maybe the research has some reasoning why they don't think this was the case.
This appeares to be a vuln in the sshd/sftpd in the Serv-U secure file transfer product… (at least, it only impacts hosts with 22 open)

Which begs the question; why aren’t they using openssh?
I agree. Something about imitation and flattery. :)

Having a service catalog is a best practice for eng teams. No surprise to see Atlassian enter the ring here.

I'm obviously biased, but I think if you're running more than 10 things in prod, not having a service catalog is like not having CI or not using version control. You can probably scrape along without it, but things will go faster, safer, and more reliably with it in place.

The true root cause of high pharmaceutical costs in the United States is our competition crushing patent system. If we eliminate patents, we open up the market completely to competition. More competition will bring extremely low prices. Innovation will not be harmed as most innovation is done in universities and is government funded, in the private innovation will happen anyways as the first mover advantage in these markets is huge.
This. When sensors disagree, you need to proceed with caution by taking a defensive stance and seek out more information. If a self-driving car can’t do that, then it can’t self drive really. I’m bearish on self driving, my uninformed take is that it is something that will require very near general AI to pull off acceptably. So it’s kind of silly, again in my totally uninformed opinion, to focus on using our current methods to do self driving. The focus needs to be on pushing toward general AI first, then just ask it to drive.
Tesla shoves fucking wooden blocks throughout their cars to resolve fittment issues.

You'd be an idiot to think they're any more motivated to properly repair vehicles than a third party.

I have always been in the "search" camp. Even on my local hard drive, grep and locate are my tools of choice.

So, no need for Google to prefer a search-based approach. In fact, I will gladly give up all my organization tools for better search, and that's why I am happy with Google's way. I actually dislike most of their UI decisions, like I hate most of the modern web/electon app design, not just Google's. But search-over-organization, love it.

I wouldn't call it a dark pattern, just not a pattern suitable for the author. I would like to say, go find something else, Google is about search and has always been, but unfortunately, the options are limited. Maybe because Google is so successful, most of the other big names go search-first, but do it poorly. They don't search as well as Google, and don't have good organization tools.
It's really not optimism, it's self-delusion that does improve the chance of sucessful outcomes.

If I recall correctly Hayek actually writes about it as some point, I can't recall exactly where though.
Ironic if AIs end up being more useful for creativity than for detail-oriented tasks.
Just a comment: it's nice to step back and think about what papers are for. I think a useful aim is to describe new findings that can help advance the field. There may be occasional "this is cool but probably useless" results, but one would expect a good paper to be one that another researcher looks at and gets inspired or boosted in their own work. My experience as a researcher is that these good papers are very easy to spot in your own field. So really I think that's what's more important, is finding the good ones, and then presumably citing them as a measure of their utility. The question of cheating of cherry picking or any kind of subterfuge is only really relevant to grant and tenure & promotion committees, media, and other external assessments. For the supposed target audience of papers, it is clear as day whether they are describing something useful or just trying to publish something

Perhaps one of the most HN replies I've ever seen. Only on HN would a photo of you be something that contains barely any information but revealing how many devices you own and how long you've had them is leaking your very soul.

I'll tell you that a photo of my son flailing out of a blanket is a deeply personal memory of a hilarious and touching moment.

That he has an electronic device is so incredibly irrelevant it's hard to put into words.

> Photos? Photos just show the shell that you won in the genetic lottery.

No, they show a moment.

If you were right, people would care about all photos being shared or none. But that's not what happens - people care about some far more than others.

This has always been so. Every generation has done something another generation later finds to be deplorable or barbaric. I would assume that we would not be exempt from this.

Oil, fast food and sleep however seem more benign, sort of like we look at the past and think, wow we have a much better way of doing this now.
FWIW, I meant race semantics similar to Java's--weird things happen but type/memory safety remains. Not the whole Java runtime model with object headers, etc.

It's obviously, uh, quite an Exercise for the Reader(tm) to figure out the best path to avoid memory unsafety given races in line with other Go priorities (as a starting point, imagine a ton of expensive atomics accessing certain pairs on the heap, downgraded to regular loads/stores if the compiler can prove it's safe). But I was trying to say it seems harder to get there now that certain things are set in stone and regressing perf of anything is going to be bad for some user out there.

This is the answer I fundamentally agree with on this subject. Super Mario 64 for N64 is a part of humanity's cultural and history, and the supply of similar items will only decrease over time. The expected value is possible for several lifetimes from now though, and most rich families struggle to hold onto it forever.

For low power communications I'd consider a 433 MHz module. Many places sell them. Here's one from Sparkfun [1].

To receive, you can buy corresponding modules but I wouldn't bother with that. Get an RTL-SDR dongle for whatever computer you want to process the data on (an RPi is great for this if you don't want to keep your desktop on all the time to do it), and use the program rtl_433.

The 433 MHz transmitter module simply sends a 433ish MHz continuous signal when its data input pin is high and does not send when the input pin is low. You encode your message into a series of pulses of the transmitter.

For example, for a project I'm doing using one of these transmitter modules I've currently got it on an Arduino for testing. Here's the Arduino code to send a message.

#define CYCLE 1000
#define W_0 600
#define W_1 400

#define INTRO_1 1500
#define INTRO_0 1500

void send_message(char * bp, int n)
{
digitalWrite(RADIO, HIGH);
delayMicroseconds(INTRO_1);
digitalWrite(RADIO, LOW);
delayMicroseconds(INTRO_0);

while (n-- > 0) {
int b = *bp++ & 0xff;
int m = 0x80;
while (m != 0) {
int w = (b & m) ? W_1 : W_0;
digitalWrite(RADIO, HIGH);
delayMicroseconds(w);
digitalWrite(RADIO, LOW);
delayMicroseconds(CYCLE-w);
m >>= 1;
}
}
}

That sends a message starting with a 1.5 ms pulse and a 1.5 ms gap, and then n bytes of data where a 1 is a 400 usec pulse followed by a 600 usec gap, and a 0 is a 600 usec pulse followed by a 400 usec gap, so 1000 bits per second after the 3 ms prefix. (The actual timing is a little longer, because of overhead).

My current test messages all start with "TZS", are 12 bytes long, and the last 2 bytes are a counter that simply increments every time I press a button. Adding this to an rtl_433 config file makes rtl_433 recognize those messages and print the count:

decoder {
name = TEST,
modulation = OOK_PWM,
short = 424,
long = 624,
reset = 1500,
sync = 1528,
bits = 96,
match = {24}0x849083,
get = count:@80:{16},
}

rtl_433 can then do a variety of things with the message, including saving to a file, sending to an MQTT server, sending to syslog, and sending to an Influx DB.

That fix was totally legit. I would considered the car better after having threaded in a brass nipple to replace the piece of crap that broke.

> To be frank, I don't see why Louis hasn't left new york / the east coast yet.

He mentions in the video that he's working on setting up another site, but he has employees in New York that don't want to move and he doesn't want to throw them under the bus by closing his New York location.
Every time I see these kinds of videos and read about Tesla valuation and messaging I can't make up my mind what to think about it. On one hand I find it ridiculous that these kinds of results so far into the development are still making Tesla the most valuable car maker, selling this as FSD with no proof they will ever reach it etc.

On the other hand they secured billions of $ for R&D into FSD and BEV design and brought EV production to scale. Their messaging is way to optimistic (borderline fraudulent) but they are doing better things with the money than the alternatives. Traditional automakers have shown to be completely impotent in this regard. Money is flowing into all kinds of wasteful bullshit (that Tesla is backing BTC makes them less trustworthy in my eyes)

I’m not saying there’s no risk. I’m saying the risk is lower. The same hazards you mentioned are also present to the pedestrian, plus the risk of TBI or death.

The way this analysis is done is that a hazard gets assigned a risk score based severity x probability. I’m saying the severity of hitting a pedestrian is higher. Put another way, if you had to choose between being struck as a pedestrian or rear ended as a driver, which would you choose?
Seems the type of thing that I would want to carve in a piece to assure that the loops of a rope wrapped around to fix several pieces does not lose and remain in place keeping the structure intact. Art just by the sake of art is a possibility, but some purpose and tool making seems another prefectly valid option.

Some way to increase grasp to remove the hoofs or the skin, or to dry it better at a fireplace could be another possibility. The purpose of the piece could be art, or tool, or food processing (maybe even the three at the same time).
That's reminiscent of that guy on Jeopardy a few years back who sought out the Daily Doubles. Even thought he would lose many/most of them, IIRC his strategy was to prevent others from scoring with them. It worked, even though he was criticized for it.

Ah, well that depends. The simplest definition is that the identity function is the only trivial compiler. One might take a more expansive view, that your Brainfuck2 language is homomorphic to brainfuck through a character-replacement table (though I must ask -- does your compiler introduce bugs if the original brainfuck source contains comments?[1]), and decide that character-replacement is trivial. You could even go further, and say that context-free token-replacement is trivial, at which point TFA counts as trivial compiler. That said, I'd estimate that most brainfuck compilers are trivial under that interpretation.

[1] if you did it right, it's idempotent, which is about as close to trivial as a nontrivial function gets under the lens of symbolic dynamics, but I'm getting a bit far afield
Could depend on the publisher as well. When I did tech work for one, changes were proposed to the author. They had to sign off, possibly offer their own modifications, and if they did there would be one more proof sent for approval.

Certain things would get edited automatically without signoff, but only if they were needed to conform to the style guide: some of that was set by the publisher, some by the journal editor.
Can we stop with the hyperbole?

The fee isn't that much for California. I could see it as expensive if it was in a cheaper state. Also, if somebody is only making $20K annually running a cleaning service in California, they need to run it as a sole proprietorship, find another line of work, or move to a different state.

I made $15K in the late 1980s in California while living paycheck to paycheck. I don't see how anybody can live on $20K in 2021. This hypothetical person would make more money working at McDonald's.
What is there to appreciate from that? That sentence is basically saying "you're too dumb to understand and use this correctly so don't bother." I find it offensive, and so characteristic of Go creators' attitude toward Go programmers.

Here's the abstract of this paper.

Minimal acyclic deterministic finite automata (ADFAs) can be used as a compact representation of finite string sets with fast access time. Creating them with traditional algorithms of DFA minimization is a resource hog when a large collection of strings is involved. This paper aims to popularize an efficient but little known algorithm for creating minimal ADFAs recognizing a finite language, invented independently by several authors. The algorithm is presented for three variants of ADFAs, its minor improvements are discussed, and minimal ADFAs are compared to competitive data structures.

Its dosage as a drug is in the milligrams range, and in that form it will be combined with many times more inert filler material, so I suspect it could simply be because a sufficiently large amount of it has never been subjected to enough energy to produce an actual explosion.

The discovery is the opposite of nitroglycerin, whose explosive properties (and the production of massive amounts) were discovered before its medicinal ones.

>5$ worth of parts and 1~2 hours of labour :)

I think you're vastly undervaluing the cost of operating a auto shop + skilled labor. $700 was the cost for an auto repair business to 1) have a skilled technician find the problem 2) devise a repair method and 3) execute the repair.

Car repair is an expensive business to operate. Rent/building costs are high, lots of expensive equipment, one of the highest insurance rates around (you're lifting expensive heavy weights up and down over people all day) and labor is us usually relatively skilled and costly.
Sure you technically have to "verify that repair is safe and meets all the coolant system design constraints". Except you don't, because common sense says most of those constraints are not critical. Like sure, the narrower ID of that 1/4" NPT nipple might cause a little more backpressure to the coolant pump. But there is no way the system would have been designed to be that marginal in the first place.

The main thing to worry about is chemical compatibility of the antifreeze to the new materials, but that's at worst a half hour to find the antifreeze datasheet. Or the mechanic already knows, from seeing the parts of other systems that antifreeze is used in.
Something along the lines of "all animals are equal, but some are more equal than others". Everyone has access to the same legal system, but some people have more access than others.
It seems Tesla, Inc. makes most of the profit by selling Carbon-Emissions Credits to other vehicles manufacturers.

I would not be surprised if they expects from that future making extra profit by "recycling" damaged structures, or something related to such structure. Something for cover the decline in carbon-emissions sales in such future.

Anyway, I think that is called "Programed obsolescence".

It's like when led bulbs suddenly fails, you know it can be repaired, even you know how to replace the bad quality capacitor chosen by the manufacturer, but the plastic encapsulation prevents it. Programed obsolescence + prevent to repair.

"Are you saying that because deer don't have what you might call generalized intelligence a data driven learned approach can't or won't?"

Won't necessarily, A data driven approach won't necessarily work.

I'm sure that given the proper learn and virtually any "program" or algorithm, there's version data-driven training that would be able install such a program., so in the abstract data-driven training would able to do "anything". But you'd need to know what to do.

But poster above said "Human learning is based on millions of different learning strategies that were encoded into the neurons of each of our ancestors". And it seems like many of those millions of years actually produced more narrow (if extremely powerful and impressive) behaviors while the generality of human intelligence is relatively more recent.

Of course, human beings "learned to learn" somehow. It's just that I think it's plausible that a specific set of circumstances were necessary. I would say the evolution of both language and complex social interactions were part of this.

"Running MPI programs on a cluster of commodity hardware" was perhaps a sufficiently novel idea to warrant a unique name back in the 90s, but these days it's more or less the standard for all but the most exotic and expensive of scientific computing... and even those expensive custom supercomputers tend to still be x86 processors running MPI code.

You're right: Journals don't do those things, publishers do. Even PloS, open access & no subscription fees, has nearly 500 employees and an editorial group for each area, which are paid. Search up their salaries, you'll fine them. (They charge about $2000 per submission to the authors. Picking at random, the most recent issue of one of them had 80 articles, or $160,000)
