> temporary-tattoo-like sensors

> Traditional electroencephalography (EEG) systems involve time-consuming manual electrode placement, conductive liquid gels, and cumbersome cables, which are prone to signal degradation and discomfort during prolonged use. Our approach overcomes these limitations by combining material innovations with non-contact, on-body digital printing techniques to fabricate e-tattoos that are self-drying, ultrathin, and compatible with hairy scalps. These skin-conformal EEG e-tattoo sensors enable comfortable, long-term, high-quality brain activity monitoring without the discomfort associated with traditional EEG systems. Using individual 3D head scans, custom sensor layout design, and a 5-axis microjet printing robot, we have created EEG e-tattoos with precise, tailored placement over the entire scalp. The inks for electrodes and interconnects have slightly different compositions to achieve low skin contact impedance and high bulk conductivity, respectively

Can they be printed on a forearm like in the Disney film "Moana 2"?
The fact that they so readily call Musk as being "narcissistic" (or "asshole" or "cult leader") reveals the rather dark nature of these "egoless" souls.

It is good to evaluate people on their actions rather than what they claim to be. We saw a good example of this in the Elm community[^1].

Another option, if the headlights are at eye level, is to move the rear-view mirror so that you see the passenger seat headrest. That makes it the perfect angle to make their headlights reflect right back at them.
Some things are easy now, but some things still require multiple lines of code: https://youmightnotneed.com/lodash. If you only need one or two, sure, just write your own, but if you're maintaining a big project... why waste time debugging these common utility functions? You'd basically just be reinventing lodash, but with fewer community eyes and tests on it. Whoever inherits that is gonna need to debug all your util functions when something inevitably goes wrong. Like for _.pickBy(), none of these are very readable (https://stackoverflow.com/questions/54743996/converting-loda...), another implements it wrong and leaves out the predicate (https://github.com/you-dont-need/You-Dont-Need-Lodash-Unders...), etc. Why do this to your project and fellow devs when it can easily be a single tree-shaken function imported from a popular, well-maintained lib?

If anything, ECMA should just absorb more lodash functions into the standard lib, like they've gradually done with some of the array functions. But common things like that shouldn't be up to each individual programmer & team to reinvent all the time. It just needlessly expands the maintenance surface and causes subtle bugs across teams & projects.

JS Date is in an even worse place. If you ever need to work across time zones on both the server and the client/browser, native JS date is totally unusable because it "loses" the original time zone string and just coerces everything into (basically) utc milliseconds. The Temporal API is supposed to fix that, but I've been waiting for that for nearly a decade: https://tc39.es/proposal-temporal/docs/. That proposal links to https://maggiepint.com/2017/04/09/fixing-javascript-date-get..., which explains some of the weaknesses of the current JS date system.
I suspect that most rails, or next, projects add additional dependencies than just the framework. Generally the framework isn't the issue in my experience.
Isn't that just the thing? Just like exotic sports cars, if everyone has one its just not special anymore. In this case it gets weird when there are multiple of them.

Scrolled through all of the comments, didn't find mention of the spelling mistake right at the top. Sorry, but spelling/grammatical errors often communicate sloppiness. Even when you worked very hard.

"Chosse your oponent"

perhaps:

and

"you win refresh to go again"

could be

"You won! Refresh to play again" -- you could even add a link to load the page again.

"sorry that was the wrong answer, the corect answer was:"

could have "correct", and a capital letter for "Sorry"

> Then run ./build.py. This will use the bootstrapped 30cc-compiler to compile 30cc itself. It then again uses the 30cc-compiled compiler to compile 30cc once again. The final compiler is then stored as ./30cc.

Why isn't that also done by the Makefile? The only catch I could see is that you'd need to have it build to different output names, but that seems fine for what it is?

Also, I'm curious - did you find yourself having to constrain your use of C in order to make sure that the compiler could compile itself? Or does it implement everything you would use naturally anyways?

(And of course, congrats/bravo; super impressive:])
I suspect ones medical provider or an urgent care center could do the same thing. My Dr has fit me in same day for something quick before and an urgent care might be only a $100 copay for the visit.

Also most people's deductable isn't 15k

Also its basically impossible to Google medical prices in America because actual negotiated prices are normally a fraction of the cash price.

Thats crazy. It would be cheaper to fly abroad to receive the treatment (except that the regime lasts 30 days). I had a regime in a foreign country a few years ago, total cost of injections was around $100 USD.
Intel is maybe a year or two behind TSMC right now. They might or might not catch up since it is a moving target, but I dont think there is anything TSMC is doing today that Intel wont be doing in the near future.
You can do it with macros, the problem is
A) documentation
B) macro abuse

It's so much harder to debug things when function calls are secretly macros, and if I didn't have the vscode cpp language server for goto definition, I'd be completely lost. I'd wager that only 5% of the #defines aren't auto generated by occasionally recursive macros. Maybe hyperbole. Makes it really hard to figure out how existing code works.

The start of democracy in South Korea was not that long ago in 1988.

I do think he was acting by himself; he’s generally got weird political instincts. Part of how he got walloped in the legislative elections was by remarking that green onions were cheap normally because of his policies, when it turned out the supermarket he was electioneering at was running a 75% off sale on them. https://www.straitstimes.com/asia/east-asia/political-leeks-...

South Korea has had exactly one president in the modern democratic era who hasn’t been indicted after their term or impeached.
The robot is completely superfluous. These are conductive ink non-tattoos painted onto the scalp. It would be straightforward to do it by hand.
Most expensive part of the typical web app is the coordination cost between front and backend devs. Thus the rational to have 1 dev implement full stack. But the trade-off for coordination costs are heavy context switching and knowledge costs to know both ends. Neither option is very ideal and most companies have accepted the coordination costs.

But LiveView just ignores these problems and does full stack without the heavy costs. Elixir/Phoenix/LiveView is a tool-set for maximizing how far one dev can go.

You'd think this would be a selling point in many companies: to have less devs ship more features but those heavy SPA stacks let middle managers rationalize hiring bigger teams. LiveView is for shipping - not stalling.
What Happened to Intel?
There are probably too many people pursuing a career in "tech" (really software) right now. I feel bad for those who are graduating into this job market, although I don't know what a better option would have been.
I think there's no way to test the bat for rabies without them breaking open its head. That was why they had to kill that guy's squirrel recently after it bit the person who worked for the government.
I passionately loathe Porsche headlights in general. The particular pattern of 4 very bright dots constantly tricks my eyes into thinking they are focusing incorrectly which is distracting and borderline painful. The Macan EV's pattern of lines rather than dots actually _alleviates_ this problem for me so I'm somewhat disappointed it's _this_ Porsche and not every other one on the road whose headlights are being replaced.
Last Christmas, we got a tree from a local farm in the mountains. We had the tree trimmed and decorated before we discovered a sleeping (hibernating?) bat on the inside.

We got it moved outside, but it took about 24 hours before I realized that I should call County Health. By that point, the bat was gone, and county health suggested I receive rabies treatment, but call my doctor. The bat could have bit or scratched without us realizing it.

The doctor concurred. Rabies treatment must be done at the ER. They strongly recommended everyone in the house receive treatment if we could not 100% rule out physical contact. (We couldn't.)

Me, my wife, my kids, EACH receiving the immunoglobulin and four rounds of vaccines at the ER. We ran the first ER out of the treatment so the kids had to go somewhere else. Also, those are big needles.

The treatment ended up billing insurance over $100,000. (Almost all of that is the immunoglobulin.) We also had to return to both ERs, three times each, with the last time being on Christmas morning.

There is research that says immunoglobulin is _likely_ not necessary if you have no visible bites, but it's current health policy in the USA, and no doctor wants to be the first to undertreat.

Most expensive Christmas tree ever.
Right, but it's not worth the parent's time.
Ironically the first epidemic lock downs in the country were done by the founding fathers themselves in responset to yellow fever. Back in the 1790s.
This sounds healthy.

I find it's good to periodically examine things that you aren't persuaded by from the other person's perspective. Dig deep a little. Ask non confrontational questions to figure out where they're at and why they're there.

It usually uncovers useful understanding, even when your mind on the surface issue isn't changed.

I am not a lawyer.

I would be a little worried about the possibility that the SEC would consider this to be an investment contract, thus making it a security, thus requiring it to be registered with the SEC, which will be a huge hassle involving very expensive lawyers.

I point to the case of LBRY inc, which issued tokens including rewarding people who made video content, spent a fortune fighting the SEC in court and went bankrupt.

There is the issue that the company would be forbidden to issue equity to some people such as people in sanctioned countries.
Hmm, weird. I run one of the larger korean music platforms and interviewing Koreans I'd have said the opposite with regards to the North-- that is, they do not want to reunify and it's the furthest thing from their minds beyond that they hate the draft.

I noticed even the North doesn't seem to be eying reunification seriously either, taking steps to destroy monuments like https://en.wikipedia.org/wiki/Arch_of_Reunification earlier this year.
It'd be a long way into the future to do brain uploading type stuff. We are not close yet but maybe in fifty years?
There are a lot of big egos in team sports, and in high performing teams you often have a team full of big egos, although there are usually a few "team players". I wonder what coaches think about ego.

Launching a major attack against Assad (a Russian ally) and an upcoming revolution against an (allegedly) pro-Russian government in Georgia all seem to fit into a pattern.

The only "pattern" between these two at least -- is that you haven't cited any direct, observable reason to believe that US agencies have been behind these events. You know, "evidence" and all that.

But rather simply -- speculation.
If martial law was declared in the US, I expect there'd be a story on HN about it.

Remember that the tetanus vaccine is often combined with a vaccine for diphtheria and whooping cough. You might not need a tetanus vaccine, but you might need the other two. As always, ask your doctor if it doubt.
What a fun project, thanks for sharing. I've dreamed of projects like this. What did you expect to learn from this project? Did you learn anything unexpected?
Models like this are experimentally pretrained or tuned hundreds of times over many months to optimize the datamix, hyperparams, architecture, etc. When they say "ran parallel trainings" they are probably referring to parity tests that were performed along the way (possibly also for the final training runs). Different hardware means different lower-level libraries, which can introduce unanticipated differences. Good to know what they are so they can be ironed out.

Part of it could also be that they'd prefer to move all operations to the in-house trn chips, but don't have full confidence in the hardware yet.

Def ambiguous though. In general reporting of infra characteristics for LLM training is left pretty vague in most reports I've seen.
I remember wanting to play GTA at my friend’s house, and it took a whole hour and lots of fiddling with the menus followed by a multi-GB update to play. We jokingly said that we were playing IT Simulator.

I have less and less patience for needy tech.
Also, looking at the code, I don't think you use "question_array" or "answer_array". And I don't know what "utah2" means.

Sorry I'm not great at games but I like looking at code and interfaces.
Unless a not-too-gruesome death is somehow not concerning to you, knowing that rabies = certain death should be enough, And at least where I grew up, rabies = certain death is taught to kids in first grade, maybe even kindergarten.
With respect to trucks, it’s people who modify the trucks height and don’t readjust the lights. This should be enforced much more!
The headlights aren't being replaced, it's just a software fix. Still a bit of a fail for Porsche if a software fix requires a dealer visit and can't be deployed over-the-air, though.
Not exactly.

There was a parliament election, with three blocks each gaining roughly a third of the seats.

The block that won the most seats (but not enough to have a majority) immediately declared they would never compromise/ally with anyone else. Essentially, if they were called on to form a government, they were almost certainly going to be immediately censured.

So Macron, rightly or wrongly depending on who you ask, decided to not call on them since he estimated it was bound to fail and waste time. Instead, he nominated someone from a (now) minor political force because, at least in theory, they were enough people willing to negotiate with them to form a majority. Looks like it didn't work in the end and now France will be stuck because no one is willing to compromise.
i've run inference on Intel Arc and it works just fine so i am not sure what you're talking about. I certainly didn't need docker! I've never tried to do anything on AMD yet.

I had the 16GB arc, and it was able to run inference at the speed i expected, but twice as many per batch as my 8GB card, which i think is about what you'd expect.

once the model is on the card, there's no "disk" anymore, so having more vram to load the model and the tokenizer and whatever else on means there's no disk, and realistically when i am running loads on my 24GB 3090 the CPU is maybe 4% over idle usage. My bottleneck, as it stands, to running large models is vram, not anything else.

If i needed to train (from scratch or whatever) i'd just rent time somewhere, even with a 128GB card locally, because obviously more tensors is better.

and you're getting downvoted because there's literally lm studio and llama.cpp and sd-webui that run just fine for inference on our non-dc, non-nvlink, 1/15th the cost GPUs.
One, and it was a nightmare. Do not recommend.
ah, the nostalgia! my visual basic stuff was much less fun than this!

feedback: Congrats on shipping! Many professional developers can't claim the same :)
Some other factors to consider

* How many years of service are included (both for the data plan and just repairs when someone smashes a bus camera). Employing people to fix/replace cameras could easily cost hundreds of thousands per year

* Where does the video go? Redundant storage in geographically disparate areas?

* How long is video retained?

* R&D costs?

* Does the price include manual human review?

* There was also some drama where the 2 vendors sued each other, idk if that has any impact on the prices

* The tickets during the pilot made millions of dollars per year, do the cameras pay for themselves?

* How much efficiency are they gaining if the program results in fewer blocked busses?
looks like it's there now
Congrats! Been running a startup off only liveview for about a year as a solo dev and it's been wonderful. Appreciate the work you all do.

Selfish demo idea: Bi-directional cursor based infinite pagination with largish datasets with state managed in the url and streaming updates that change the order of the results. Like some kind of soft realtime leaderboard.

With long render times (morphdom bench on large sets isn't great as far as I can tell) it's hard to escape the jank. Particularly on slow connections.

Completely fine and the kids are growing (up fast).

I fail to see how one has anything to do with the other.

Knowing and applying both Java and Typescript is not an issue at all. What is a pain is CSS and why I tell everyone I'm a BE dev. But I happily build vertical slices of functionality where I have full control over FE and BE code and can adjust as I see fit instead of having to create or follow a rigid interface definition and where the BE isn't user testable when it gets written. What is a pain is the libraries on the FE but that's not an issue with knowing multiple programming languages but with the web dev FE ecosystem in general. A non full stack FE developer would have the same pain.

While we did learn a programming language at university to code our exercises in, we didn't learn that language specifically as "this is the language we teach and this is what you will use in your job until you retire". On the contrary we were told and taught about programming concepts, data structures and algorithms and it was expected that you can program in any language. The (mandatory) operating systems course for example would just assume that you learned enough C by yourself to do the programming exercises. We had to write a working memory compactification algorithm for Minix. In the scripting language course (non mandatory) you had to choose any scripting language you wanted and implement a project in it. In the mandatory hardware course we were expected to pick up enough VHDL to implement whatever we learned in the course.
That's true, though I would argue that, especially around regional transit hubs, at least some number of parking spaces should be converted to pickup/drop-off spaces (3/5/10 minute parking). It's inane how hard it is to find a legal place to drop people off at some BART stations, and surely it's worth sacrificing some small number of parking spots for?
