> - Poor CRI and SSRI

So having a minimum CRI of 80-90 is a good starting point, there are issues with the CRI measure itself:

> Ra is the average value of R1–R8; other values from R9 to R15 are not used in the calculation of Ra, including R9 "saturated red", R13 "skin color (light)", and R15 "skin color (medium)", which are all difficult colors to faithfully reproduce. R9 is a vital index in high-CRI lighting, as many applications require red lights, such as film and video lighting, medical lighting, art lighting, etc. However, in the general CRI (Ra) calculation R9 is not included.

Walking 1 hour round trip to work was the sweet spot for me. Exercise, easy to go to the gym either side, listened to podcasts, had a mental transition to and from work, and walking is fine in basically any weather or season.

Now I work from home and it's nice but it has a whole set of mental challenges. I'd go back to walking if I could stand being in the office.
When humans build a dam an ant hill might get destroyed.

Humans don’t hate ants, they just have other goals.

In the case of an unaligned superintelligent AGI those goals may be something that just happens to satisfy its reward function but is otherwise “dumb” or unintentional (like making a lot of paper clips).

Intellectual capability does not get alignment for free.

What you see in the communicated text interface and the goals/system behind it are not the same (that cartoon with the smiley face), and we don’t understand how to evaluate the underlying state.
This is the frustrating thing about LEDs that IDK we can change.

If there was a "DC" light socket in the house we could have LEDs outlasting owners, and for cheap. Nearly all the expense of LED bulbs is the power supply. Everything else is dirt cheap. A single home DC power supply with ~200W of output could light an entire house, flicker free.

What's even more frustrating is I think we could fix it. A national regulation for DC light sockets would fix it. Mandate a voltage, shape, and max amperage and BAM, you'll get 1000 different manufactures making standard compliant bulbs and home power supplies that will last an eternity.

Fine as in drinkable? Sure. But if you want delicious coffee, with great aroma, crema, etc, there is a big difference between fresh roasted beans and something that has been sitting on a shelf for a few months.
Agreed the e-waste issues are real, but how did you get incandescents to last 10 years? I replaced every dang one after 12 months or less, every time.
Seems like a great time to start designing space heaters that accept 10-20 E27 incandescent 'heating elements'. (Well, until this is banned too.)

Correct. My phone isn't a "dumb phone", but it is certainly "dumbed down". I think that the people partially adopting or experimenting with using dumb phones are doing so to curb habits or escape something. Oftentimes, I think this can be done by simply dumbing down their existing smartphone, or "locking down" as you put it.

Double negative. Ticked the "bugger off" answer to the yellow envelope and Schufa simply infinitely pisses me off. With omnipresent requirement for Schufa report and how they upsell their useless predatory subscriptions on attempt to obtain the free report.
For me, the biggest issue with LED bulbs is flicker. And there's a lot of variation between different bulbs, even ones that claim to be flicker-free. There are metrics for quantifying flicker [1], and hopefully they'll be required to print this on the packaging at some point.

For now, I always go to see bulbs in person before buying them, and record them in slow-motion video on my phone. This makes it easy to tell which ones flicker badly and which don't.

Kelly was an absolutely amazing person. A giant.
I found this article very interesting that talks about what you're asking: https://www.ratherlabs.com/post/biggest-mistakes-first-time-...
I'm inclined to personally agree, but we need to at least acknowledge the counterpoint. That being, in a cliched phrase, that "the Constitution isn't a suicide pact."

Or, in the words of Jefferson, "The laws of necessity, of self-preservation, of saving our country when in danger, are of higher obligation."

That's the claim being made by lawmakers: that certain trade constitutes a threat to national security. I'm not really seeing much debate about that claim.

If I understand your point correctly, you're instead saying we already have the tools to ban TikTok (presumably under commerce laws) and we don't need any other means.
espressos made by a professional with bar better, more consistent equipment and tons of practice.

There are a lot of coffee shops near me. I'm surprised at how bad some of the espressos are, a lot too sour, some too bitter. Prices keep going up. You can count the break even point in terms of money, sure, but in my house, the espresso machine paid for itself almost instantly in terms of satisfaction.

> But, it did take optimizing house location/commute, etc

To spell the quiet part out loud here, what you're describing is an extreme privilege in a world where homes near tech campuses often go for $1M+. New fathers aren't going to have a down payment for even $600k+. Tech at this point starts as a rich persons game which is why so many tech workers intermarry with other wealthy people. It takes two or a trust fund to do what you're talking about early on, unless you want to rent in a place where rents are highly inflated. At that point, you're choosing between a family and any shade of financial freedom.
They flicker, they die, and all at a more rapid rate that old school bulbs, despite the boxes saying they'll run 10 years or more. Ridiculous.
>Does nim have anything as polished and performant as clap and serde?

"Polished" and "high quality" are more subjective/implicitly about adoption, IMO. "Performant" has many dimensions. That said, I just tested the Nim https://github.com/c-blake/cligen vs clap: cligen used 5X less object file space (with all size optimization tweaks enabled in both), 20% less run-time memory for large argument lists, and the same run-time per argument (with march=native equivalents on both, within statistical noise). cligen has many features - "did you mean?/suggestions", color generated help and all that - I do not see obvious feature in clap docs missing in cligen. The Nim binary serde showing is unlikely as good but there are like 10 JSON packages and that seems maybe your primary concern.

More to add color your point than disagree (and follow up on my "adoption") - your ideas about polish, quality, docs, etc. are part of feedback loop(s) you mentioned. More users => Users complain (What is confusing? What is missing? etc.) => things get fixed/cleaned up/improved => More users. Besides "performant" being multi-dimensional, the feedback loop is more of a "cyclic graph". :-) Or maybe this is just a sub-graph of "ecosystem richness". While I probably prefer Nim as much or more as @netbioserror, I am not too shocked by the mindshare capture. It seems to happen every 5..10 years or so in prog.langs.

While many of your points are not invalid, tech is also a highly hype-driven & fad-driven realm. In my experience, the more experience with this meta-feature that someone has, the more skeptical they are of the latest thing (more rounds of regret, etc.). Also, that feedback graph is not a pure good. Things can get too popular too quickly with near permanent consequences. ipv4 got popular so quickly that we are still mostly stuck on it 40 years later as ipv6 struggles for penetration. Whatever your favorite PL is, it may also grow features too fast.
Little known, but according to Harvard Business Review, all Chinese companies with over 50 employees must have a dedicated CCP representative within the company. Every company with over 100 employees must have a party cell, and the leader of that cell must report to the local municipality regularly.

Bambu Lab... how big they are isn't clear. Their LinkedIn claims they are between 201 and 500 employees. If HBR is correct, they very likely have CCP cells within their organization.

You can go buy high CRI, high quality bulbs right now. Nothing is stopping you.

Here is one common vendor: https://store.waveformlighting.com/collections/a19-bulbs/

The issue isn’t that MBAs have cost reduced bulbs for no reason. The issue is that 95% of consumers will only choose the cheap bulbs, period. As a result, that’s what gets produced at scale.

> We know how to mass-produce quality LEDs to the point entire TVs are made of the things.

They’re not the same thing. Displays are optimized for specific R, G, and B color points. White LEDs are optimized for full, smooth spectrums.
So in addition to what akasaka said (another thumbs up for line profiler from me, great tool) this isn’t a problem with linalg.norm being slow. It’s plenty fast, but calling it thousands of separate times in a Python loop will be slow. This is more just about learning how to vectorize properly. If you’re working in numpy land and you’re calling a numpy function in a loop that’s iterating over more than a handful of items, chances are you’re not vectorizing properly
Sounds more like a devil's advocate writing prompt than an argument a sane human would try and make
I've set up Kelvin[1] to lower the colour temperature of my LED bulbs in the evening, and reduce their brightness. In fact, they end up pretty deep red when doing middle of the night bathroom runs.

[1]https://github.com/stefanwichmann/kelvin
Wanted to give a tentative endorsement to Cree. I bought a box of LEDs at the hardware store and about a third of them failed early. I wanted to spend good money on good product; Cree is well-regarded, and so far (a few months) I've been way happier with their bulbs than the cheap stuff.
I've moved three times with one set of cheap LED bulbs without having to replace a single one. I'd have gone thorough dozens of incandescent bulbs in the same time period. I'd have also burned my hand on a few.

LEDs are definitely simpler than incandescent from a user perspective.
One might argue that international conflict has always served primarily as a pretext to impose domestic social controls, at least since the cold war started. What I'm saying is that the ruling classes in China and the US arguably have more in common with each other than they do with their common citizens and the appearance of conflict is useful for both sets of elites.
You're right though I want to mention the LEDs are also damaged by the heat, their color temperature will wander, lifetime will be reduced, and brightness per watt will also be reduced. Still useful for projects and areas where perfect lighting isn't as important.
I now feel better about adding additional check to disallow logins from not our domain to our apps even tho technically app setup in azure wouldn't allow that anyway... fuckup can happen at any level
> It took us decades of use to understand the harms of bpa, which are still disputed by 'industry science's despite the existing research.

https://www.fda.gov/food/food-additives-petitions/questions-...

> Yes. Based on FDA's ongoing safety review of scientific evidence, the available information continues to support the safety of BPA for the currently approved uses in food containers and packaging. People are exposed to low levels of BPA because, like many packaging components, very small amounts of BPA may migrate from the food packaging into foods or beverages. Studies pursued by FDA's National Center for Toxicological Research (NCTR) have shown no effects of BPA from low-dose exposure.

-------

FDA isn't "industry", they're the government regulators in charge of food safety of the USA.

So we swapped from one plastic (BPA) with a century of research to other plastics with no research. They're all going to "leach" into our foods because when food comes in contact with molecules, it will absorb those molecules.

If you cook food in an iron pan, the food will have more iron content. If you cook food in a copper pan, the food will have more copper content. Its just how things work. The question of safety is about studying the effects of iron, copper, or... BPA. And as far as I can tell, only low quality alternative-medicine journals seem to ever have anything to say about BPA.

I'm not at liberty to share those discussions with you, but I respect you for asking. I can point you to what was shared with the public:

"The current macroeconomic environment is tough, and as a result, companies are still spending but they are taking a more conservative approach to software investments and are taking more time to make purchasing decisions."

Do you think that's a lie? Some businesses have stacks of dollars, but how fast will that value be inflated away? Some businesses don't and rely on credit to cover payroll. That just got more expensive due to interest rates. Our CEO said "Businesses are making decisions differently". Or said another way:

The Macro environment has effects to all businesses.

Your original dunk attempt was "everybody, myself included is just parrotting and blindly following" and I attempted to explain to you that everyone is in this new macro environment (driven by the changes to cost of money, as well as increased money supply) together and is adjusting business expectations accordingly.

Do you think interest rates and the influences to macro env are not the driving factor impacting business decisions right now? Would love to hear what your contrary thoughts are beyond "business leaders are all sheep, myself included".
I was diagnosed ADD (or what would now be called inattentive ADHD) in my 30s. But the testing results were not clear, in part because I'd developed a lifetime of coping mechanisms and skills that allow me to behave in non-ADHD ways through force of will. If I look back at my primary school report cards, they are a mixture of both gifted and below-average performance with teacher comments like "Does amazing work when he applies himself".

That sudden lack of motivation or drop in performance on tasks that we previously excelled at is also classic ADHD.

Anxiety is often a comorbidity, stemming from a feeling of inconsistent failure and lack of control. Though my understanding is that anxiety may be more present in women sufferers of ADHD where the disease manifests differently than in men.

All of this to say that you may feel like a DSM definition of ADHD doesn't map onto your experience, but that may be because you're an adult who has a lifetime of adaptation.
> Python is a superb API for researchers,

Where does this nonsense come from? No. It isn't. It's just a stupid fashion. Something that should be discouraged, not encouraged by trying to make it work when it's obviously broken.

As someone who does work with researchers who do use Python a lot, I see the everyday painful experiences of people who use it. And this pain doesn't need to be there. It's just masochism. And the only real reason is that they don't know any better. The only other thing they know is Matlab, and that's even worse.

Python is just a bad language. Popular, but awful. Ironically, while researchers are supposed to be on the forerfront of discovery and technology... well, they aren't. Industry outpaced research. So much so that today there are government programs to onboard researchers into more automated and more automatically verified way to do research. And we aren't talking about making an elite force here. These programs are meant for people in research who copy data from Excel sheets one data point at a time into another spreadsheet. It's that kind of bad.

My wife happened to work in such a government center, and that's how I know about what's going on inside these programs. And it's very sad that decisions about the preferred tools for research automation are made by people who, unlike most of their peers, had some exposure to what happens in the industry, but had no deeper understanding of the reasons any particular technology ended up in any particular niche, nor any independent ability to assess the capabilities of any particular tech. It's really sad what's going on there.
Keep in mind: all LEDs leak blue light even the warm ones (color is achieved by average so you can have high red and high blue and it looks balanced visually). These bright blue leaking LEDs are great during the day — especially those with high CRI and R9 values. But not at night when you’re trying to go to bed! Switch to incandescent only in the evenings until they figure out blue-less dimmable LEDs
Show HN: DomainsGPT – GPT-Powered Domain Name Generator
Hello Hacker News! Steven here – very excited to be launching DomanisGPT!

Some of you may remember One Word Domains, which I launched back in 2020. It gained significant traction after being featured on the front page of HN for half a day (https://news.ycombinator.com/item?id=23291337). So, launching DomanisGPT here, almost 3 years later, feels incredibly special.

Interestingly, this isn't my first attempt at building an AI Name Generator for One Word Domains. I first tried in early 2021, long before GPT-4/ChatGPT existed. As part of my undergrad NLP thesis, I trained a Markov Chain on 100,000+ company names, stored it in S3, and hosted a Flask API endpoint on EC2. It was decent, but nowhere near the level of quality I wanted it to be.

Now that OpenAI's APIs are available to use, I decided to give this another shot! Hope you guys like this, and please let me know if you have any feedback about it!

> why are you acting like you need a college credit in an LED survey course in order to buy incandescent-replacement LEDs? It's like a new vocabulary of like 5 terms/concepts that can all be summarized in a sentence or two.

I hope by "you" you are also including TFA and the comment I was replying to, right?

Your response directly contradicts TFA. I don't know who is right, I just know I'm not entirely satisfied with the LEDs I have. It's not my most pressing concern, but I'd rather not have to deal with 5 concepts when picking a lightbulb.
To be fair, not being webshit is part of why their UI is usable (if not great) on low-end hardware.

BrightScript does suck, though—but it also already exists, and I doubt maintaining it's all that hard. Used to work on a dual-platform mobile app engine that was probably on par, difficulty-wise, with maintaining & developing BrightScript—that only needed like 3.5 devs, and not at coastal US wages.

Meanwhile, the Big Boys get a C++(?) API, as I understand it. I assume that's why some of them behave weird or are glitchy, but do look a lot like the same apps on other platforms.

[EDIT] However, they could probably do a good job making a comparably-snappy UI with JavaScript, as long as they didn't drag HTML and CSS along for the ride. Kinda like the JavaScript API on tvOS.
