Gaining expertise in cars/computers doesn't really translate to health medicine. It's a fallacy that I saw first hand, that say, some one gains expertise in one thing then feels confident to take on another in DIY spirit. A concrete example is someone who builds a shed that thinks they can do a bathroom renovation/remodel or build their own cabinets (don't look at me :P).

Having to throw in the towel and hire a professional I saw:
- How experts do things much faster (literally 1/3rd the time).
- How experts avoid conflicts ahead of time/or deal with them as they arise quickly
- How experts know the name of all the things ahead of time
- How experts realize when a problem is out of their wheelhouse and requires a referral (electrical/plumbing/etc).

I had to call it quits mainly because the DIY spirit is instilled into me by my father and love for tinkering. But I see it in my father, he tries to repair his own cars (with good results), because in his words mechanics are a scam and for the longest time I kind of assumed so too, but the truth is expertise is invaluable and what you are paying for is time/knowledge.

You don't expect yourself to go to med school to diagnose your problem, someone has already done that and you can leverage that.

Data collection for adversarial training was also my first thought. The same training data used for classifying images as AI-generated can also be used to train the AI to generate images that fool more people.
Yes. Making deals to distribute their software is a well accepted practice and Chrome is far from the worst thing to come preinstalled. Advertising your wares on your own website is even more reasonable than that.

Observing when a competing browser is used to visit a competing site and then having the desktop OS open a popup crosses a very different line.

The nice thing about this is that it is optional. I am not the Internet Police; I can't force you to adopt this.

I've heard anecdotally that American self-improvement folklore is about "how I can improve MYSELF to be the winner" whereas alternative mythology is about "how can I gather a TEAM so that we win against other teams". Tennis player vs football quarterback mentalities.
There is also a 1000X difference between a nanosecond keystroke delay and a microsecond keystroke delay. So that must be equally relevant since 1000 = 1000.
People are full of contradictions but the internet tells me 44.5% of U.S. households own dogs. Did those right leaning religious people own dogs, and would they have said, "Sure my pet is not conscious?" if asked?

Or was it only the delicious animals they love cooking that aren't conscious?
Start interviewing! Get experience! Don't expect every interview to result in an offer. Take each interview as practice. Honestly, the first 10 companies you interview with, you should fully expect rejection, so don't go after your dream jobs immediately.

Interviewing is a skill just like ML and coding are skills, and you need to practice to do it well. And the best way to practice... is to do it!

And frankly? Everyone should be interviewing on a regular basis, anyway. Always keep an eye on the market and be ready to jump if something better comes along.

Best of luck!

A concern I've had with past studies has been the dosage of processed foods. It's better to avoid them altogether, but I haven't seen many seeking to find limits on how one can safely have X percent of their diet be from ultra-processed foods and still be healthy.

It seems like the biggest correlation between overall health and processed food intake is that processed foods are calorie dense and lead to weight gain. If excess calories are coming from sugars and unhealthy fats, and one is consuming large amounts of bad additives, that will surely lead to bad outcomes.

What I would like to see is isocaloric studies, where individuals get plenty of fiber, micronutrients and a good macronutritional balance from "healthy" foods, but are also allowed some reasonable percentage of their daily intake to be processed.

Maybe it's the guilt of feeling like I'm a weaker person for being addicted to having desserts or chips on a regular basis, but I also feel like they are pleasures of modern life that are worth enjoying in moderation. I mainly strive to eat healthy for all my core meals, and allow myself ultra-processed snacks, while not gaining weight.
Africa probably refers to the Haya people of Tanzania (https://en.wikipedia.org/wiki/Haya_people), developing carbon steel 2000 years ago. And it's well known for Turkey, China, and India right? I don't know about the part about knowledge transfer, there is also Celtic steel going back 2800 years, but 4000 for Asia with Anatolia.
That's a reasonable point. I was just modelling on how WebFinger works. A sufficiently secure hash might be sensible.
That is too expensive. Its an interesting technology but it can't possibly cost this much and it wont meet its potential if this is the price they are going with.
Couldn't this be handled in robots.txt?
I guess you could argue that, but it's strange that people want to give a student's first project (with a lot of huge mistakes like thinking node is going to outperform C because they didn't turn optimizations on) so much interest. I think people are taken in by big numbers and assume there is something cutting edge because they don't know any better.

The results are just some particles in an extremely basic pattern, there isn't a lot of payoff.
> The production of hydrogen is energy-intensive. It takes 50-55 kilowatt-hour to make 1 kg of hydrogen and 60 kg of hydrogen to make 1 ton of steel.47 The production of 1 ton of steel from hydrogen thus consumes 3,000 kWh of electricity, which is ten times higher than the electricity use of an electric arc furnace making steel from scrap. Consequently, hydrogen-based steelmaking requires roughly ten times more wind turbines and solar panels than scrap-based steel production – and thus ten times more steel.

Despite being very inefficient, it feels like this is the option we’re going to go with anyway, because the suggested alternative of reducing material consumption seems completely out of reach of human behavior as we know it. Sadly.
Most people buy pea protein isolate. This is a more complex product where the protein has actually been separated from the remainder of the peas.

You failed to read the abstract of the paper you linked.

> antidepressant effects in patients with mood and anxiety disorders that were previously resistant to treatment.

_Resistant to treatment_ is the key phrase. That means there were already attempts to treat it, i.e. it isn't a first-line treatment.

Have you ever taken Ketamine? Have you ever talked to a professional about it? No psychiatrist will tell you it is a first-line defense.

Ketamine IVs are significant treatment. Not all insurances cover it. Ketamine IVs require a significant time investment (2-3 times per month, 2-3 hours in treatment and you can't drive yourself -- not an issue for Elon, of course). You're a barely walking meat sack after Ketamine.

Ketamine in compound form is for daily at-home use and is debilitating, typically used prior to bedtime. But that isn't how Elon is describing his usage.

The fact that investors said it was "recreational" should be a warning sign. And his combined use with MJ is very concerning; you don't treat depression with a depressant. If he truly is 'depressed' he should have had professional advice to quit MJ.

Interesting to hear, thanks for sharing.
It’s actually pretty accurate for the images I had on hand. It only failed once you started giving it artwork rather than photos.

Low quality/distorted images also come out as AI
AI == An Illustrator!?

You got me thinking down the path that sometimes when people say AI they mean something very different than what I thought AI meant.
The alternative is counterweights. Not exactly new, but there looks like there is enough space for them in this case. The ones in the house I grew up in were a pair of concrete cylinders on either side of the door, maybe 10-15 cm in radius and 1m in length, mounted vertically. Not sure why they're not more common - seemed a completely reliable system.
This is where I’m stuck. The ecosystem we have today has evolved over >40y in lockstep with new hardware and technology, in a feedback loop of technological development. It is pretty resilient (from an evolutionary perspective). It includes layers of abstraction that hide enough complexity for humans to use it, but an AI doesn’t need this crutch; if we delegate the code writing responsibilities to it then what happens to this ecosystem? Purely from an economic perspective it is likely that in the limit we narrow down to the most efficient way to do this, which will be a language designed for AI, and dollars to donuts it’ll be owned by Google (et al). Will Python4 (etc) whither and die on the vine, due to lack of investment/utility? Then what happens to technology?

Certainly, I had heard about those, but not the romance scam thing which I think is odd.

Romance scams are crazy profitable and have been for a long time. It seems the new techniques is to combine the romance scam with the binary options scam which trick people by presenting them with a false market where they think they're trading geniuses so they pour all of their money into the trading platform and sometimes all of their families money whereupon the money is stolen.

I enjoyed the movie The Beekeeper purely because of the violence metered onto scammers - I hate those *%$& with every fiber of my being.
No problem, and I highly recommend using OpenCL to get started, it's actually pretty short and straightforward (lookin' at you, Vulkan compute!). So basically, the stuff in the for-loops you had before, that's the kernel you'll be writing.

I daresay it's actually easier to render things this way than getting lost in the weeds with API docs etc. A simple Mandelbrot hello-world example should be easy to understand and get compiling, and you can go from there.
No one seems to have mentioned what is most obvious to me about this: if this goes through, Google will corner the market on mobile (on-device) AI. They already have Android users, this would give them iOS users too. Not a large market right now, but the way things are heading it could prove significant in the future.
I think there is definitely merit to your statements. I believe the future of the average software developer job involves a very high level language, API integration, basic full stack work with a lot of AI assistance. And those roles will mostly be at small to medium businesses who can't afford the salaries or benefits that the industry has standard in the US.

Almost every small business I know has an accountant or book keeper position which is just someone who had no formal education and the role is just managing QuickBooks. I don't think the need for formally educated accountants who can handle large corporate books decreased significantly, but I don't have any numbers to back that up. Just making the comparison to say I don't think the hard / cool stuff that a lot of software developers love doing is going away. But these are just my thoughts.
So I recently helped my dad replace 2 of these springs. He is no engineer but used to be a firefighter and straight up told me "you don't respect the power of the spring....you will die" I don't think he ever had to respond to a call where someone died trying to do this....but I bet he had some local story of the dangers these pose growing up.

TLDR treat dangerous things with respect and you vastly increase your odds. Be it a firearm or a chemical or a fast spinning lathe.....danger can be lurking anuwhere and when you recognise it a d stop and develop a aproach to mitigate risks.....you can help elimate stupid mistakes that could really cost you.

TLDR its better to have annoyingly boring procedures than just wing it and hope it goes well.

Uber and Lyft pulling out of Minneapolis is a good thing. Why? Because those companies are in California. That means the profits are leaving Minnesota and going to California.

Sure, a Taxi company operating in Minneapolis could be California owned and the profits would get funneled back to California too.

What would be better is if locally owned Taxi companies created their own ride sharing apps. Or even better, if the drivers themselves were able to create some kind of co-op company that managed the ride sharing application for them.
> Is an article in the same publication (low tech magazine) that hasn’t even been written.

It seems particularly odd as a first citation too.

I assume the article is written, but is unpublished. Better, but less than ideal.
Almost all of your points are because what you are describing isn't bike infrastructure, it's a line of paint on a highway's shoulder that use to be a pull-over safety shoulder - that's why they terminate randomly, don't have any barriers, there's random/low density, and direct sunlight). It's literally a political line in the road to get federal money from the DOT, which is why it shouldn't be counted as bike infrastructure. It's a literal line on a state highway.

Any real conversation about bike infrastructure would need to start with recognize a political line in the road is not real bike infrastructure any more than Amtrak using freight lines is a real passenger rail route.
Laughable opinion as a fellow American and New Yorker. A bike crash is an unfortunate, and potentially scary event. A car crash is often life threatening or fatal. You're just not weighing the cost of each type of incident properly
That's not Musk talking, it's the drug talking. The problem is that in the general case, you will not be able to tell which is which.
my ex used to complain of frequent and recurring headaches, and frequently and recurrently ate Maruchan ramen noodle packets on a completely empty stomach. pretty sure they'll still not appreciate the nuance of an inconclusive meta review—but in case i pass it on anyway, thanks OP. didn't realize this was a topic of study.
> I mean if you need to do performance analysis on a software just recompile it. Why it's such a big deal?

Not having them enabled on all dependencies makes them significantly less useful if your application interacts with the system in a meaningful way. "Just recompile" (glibc + xorg + qt + whatever else you use) is a very hefty thing.

Having them enabled by default also enables devs to ask their users for traces. I can reasonably tell someone to install sysprof or something, click a few buttons and send me a trace. I cannot reasonably tell them to compile the project (+ dependencies). And tbh, even devs cba if they have to jump through too many hoops.

> We talk a lot of energy efficiency these days, to me wasting a 2% only to make the performance analysis of some software easier (that is that you can analyze directly the package shipped by the distro and you don't have to recompile it) it's something stupid.

We're trading all kinds of efficiencies for all kinds of niche benefits all the time. This enables analysis of what is shipped in real use across the whole stack with the alternative being much less useful or a lot more (human) work. To me it's worth 2% and I'm shocked (well... not really) it's not for more people.
> Can you imagine other great authors doing the same — even with a form letter?

This isn't so hard to believe. I have emailed and gotten a response from several people who are fairly famous within a niche that I'm interested in but am a lay person at.

I think folks would be surprised at how receptive many semi-famous people are to a thoughtful question or comment related to their work. Once you get to a certain level of celebrity this all goes out the window and not every message will get a response, but sometimes you get a neat message back.
it has like 90% success rate against clostridium difficile, usually with just one transplant, and it's becoming a more standard treatment (as opposed to the "last resort" definition it has had until recently). It will likely turn out useful for other diseases, but the data is not there yet. Adverse effects are, broadly speaking, the ones that you might expect from putting bacteria in your GI tract.

The hacking opportunities will be endless. Feeding AI the exploit will be new.
Also appears to disagree on the electric arc furnace. 300 kWH is apparently close to the theoretical minima for steel melting and arc furnaces are somewhere around 440 kWH. Which frankly, being that close to the minima seems fairly impressive on the scale of industrial steel melting.

The general note about blast furnaces using more energy in the form of coal and gas is probably still relevant.

I think India famously produced wootz steel quite early, right?

Anyway, I’m not really sure what they mean, I’d assume steel was invented in a bunch of places. Is getting carbon into your iron a rare accident to make? I’d both be shocked if European steel makers didn’t integrate information from around the world, and if they didn’t integrate information from local sources. (like the Celts, famously fans of the stuff, right?)
Reading some of the comment section here makes this veteran DIYer sneer. Ya’ll need to “grow some” and unlearn helplessness.

Pay someone else who learned the simple steps to do the simple work and save yourself the time for more productive activities, but stop congratulating yourself on “avoiding a disaster” - too much drama for the task at hand here.
Either make or subsidize someone to make under $1000 monitors that fit their specs.
Yep, pretty much. Right now filesystem^ sources are finite, scanning the target path at operator startup time and processing all matching files. This processing is done by opening an asynchronous reader, courtesy of the object_store crate.

^We call these Filesystem Sources/Sinks to match terminology present in other streaming systems, but I'm not in love with it.
It just says 'no optimization flags' and that's that, I don't think even the compiler is mentioned so the author is not giving you a lot to go on here - you don't even know what the default is.

A modern C optimizing compiler is going to go absolutely HAM on this sort of code snippet if you tell it to and do next to nothing if you don't - that's, roughly, the explanation for this little discrepancy.
I don't know about Africa, but it is not exactly controversial that China and other places had high quality steel before Europe.
The thing that strikes me as particularly weird about this is the use of numpy there. In other languages, they're using native code. In python they're reaching out to numpy, which is a great library, but not awesome inside a hot loop unless you're keeping the operation you're carrying out within numpy itself. This means, right in that hot loop, they're doing a lot of translating of numbers between python representation and native c representation.

Cutting numpy out by making the line "t = [0.0]*l" gets it down to 17059 ms, without attempting any other optimisations. Using that plus pypy (so you get the JIT that you have with javascript/v8) gets it down to 958 ms.

To show the cost of those translations, sticking with numpy. If we switch that inner loop to:

temp_t_i = t[i]
temp_t_i += 0.02 * j
temp_t_i *= 0.03 * j
temp_t_i -= 0.04 * j
temp_t_i /= 0.05 * (j+1)
temp_t_i = temp_t_i

It speeds us up from 47552 ms to 28251 ms. Almost half the execution time. That's still doing two hops back and forth, though. If you cut it down to a single line it's even faster at 18458 ms, cutting execution time down to about a third of the original example. Pypy isn't able to help here at all, this is sort of a pathological case for it.

edit: I'll add, I'm not that good with numpy, rarely use it myself. Not sure if it's possible to do that inner loop all within numpy somehow. I imagine that'd be a lot faster still.

Companies like Coca Cola overplay the benefits of exercise as the solution to health problems so they can continue to sell ultra processed "food" with an extremely healthy profit margin.
