Not OP, but the reason is because that the values that you’re looking for tell you how to do the weighings, where the rows are weighings and the columns are the indices (it’s easier to see if you don’t translate from {0,1,2} to {-1,0,1}). Because of the problem you need the same number of balls on each side of the scale.

By choosing 7-19, omit 13, you finding the center values of the range 0-26. This is important because when you write the values in ternary each column has the same number of 0 and 2 digits.

This would not hold if you simply used the values 0-12, for example. Then the first column has eight 0’s and four 1’s, so it does not correspond to a valid weighting.

It’s important to note that this method doesn’t work for the problem described - it only works if you know that the odd ball out is heavier. You can see my other comment for a description of why, and a working solution.
> Advertisers aren't altruistic and don't voluntarily subsidise poor people's access; advertisers want to target people with money.

Yes and no, since at the same time _almost everyone can be monetised_, just at a lower CPM. Everyone, almost everyone has _some_ money they could spend on useless crap. The goal of advertising is not to inform (or "connect people with the brands they love") but to create a need. This is not much different from poor people spending money on lotteries or in-app purchases in shitty mobile games.
> I don't want to eat empty carbs, anywhere near as much. Because I feel like they make me feel sick.

I did a keto diet obsessively for a while and I still have a psychological revulsion to drinking coke or eating cake even a year later. Those sorts of things are long term wins.
> I'm at Google and I wish each engineer got some kind of budget (like the peer bonus budget) that could be used to distribute funds to third-party libraries.

One of Andrew Yang's policies when he was running for president was to give every American $100 to allocate to whatever non-profits they wanted. This is really the kind of policy we need to drive open source. I'd love to open source more software myself, but right now the thought have having 25 million people using my code commercially and making maybe 5k a year if I'm lucky isn't super appealing.
> I’m totally for behavioural policies for obesity, such as don’t buy sweets, go for a walk each day, or make sure to eat vegetables each time you are hungry, etc.

So are physicians, and most patients. It's just a lot harder than it sounds to sustain. There's the old adage that "the definition of insanity is trying the same thing over and over expecting different results"; attempting to cure obesity by telling patients "exercise more, eat less" is precisely that.
> lack of a predictable regulatory landscape in Europe

It is predictable though, and has been clear for ten years. They are on the side of users privacy and clearly against invasive tracking and particularly profiling.

Out of curiosity, what do SFDC data export costs currently look like?

If you are expressing your opinion on a topic, unsolicited, in a public forum, you are absolutely promoting the held opinion and seek to influence others by the act of sharing it. That also connotes that you place importance on the topic. Choose your battles judiciously.

I personally disregard anything that is opinion from anonymous sources. It is literally a worthless opinion, regardless of topic. The worth of an opinion is largely based upon knowledge of the source. Is it someone I trust? Is it someone I respect? Or is it someone who has been consistently incorrect or shown to be a liar? If the opinion held is worth sharing, then it is worth sharing with attribution to a real person. You need to have skin in the game.

Sometimes it is important to share an opinion in order to inform change, be it societal, policy, etc. Silence is the acceptance of the status quo. But again, choose your battles judiciously.

A lot of the replies really zero in on the example topic of incest, rather than abstracting actual subject. Like delving into the backstory of the characters in a word problem. Weird.
I'm Co-founder/CTO of HubSpot.

There are many things I admire about Salesforce.

But, we decidedly don't want to become like Salesforce when we grow up. We have been committed to SMBs for 16+ years now, and not planning to change that anytime soon.

They have grown through a lot of M&A, we built our platform from the ground-up for SMBs.

There is room in the market for both Salesforce and HubSpot to succeed. Salesforce for large enterprises (the Fortune 1000) and HubSpot for SMBs.
Custom keyboards are great. :-)

In addition to custom firmware, the other benefit is some custom keyboards have designs which are more coherent than typical keyboards. (e.g. replacing the gigantic spacebar, with more keys so that the thumbs can be more useful).
Free-rider (not loader!) has an economic meaning. It is easy to attack a post when you put words in peoples' mouths.

The EU shares common regulatory characteristics as well as a common capital market often. Comparing the two systems is not "nationalistic flamebait" and I find it sort of absurd to suggest so.

Different economic systems have an impact on people's well being. I didn't realize it was verboten to suggest so.

i hate to trash writers who need to fill a page. It's their job. But, other than reminding people that the X app is an idea Elon bruited early on after acquiring Twitter, there has been no news since.

It's the hyperloop of apps. Except even less relevant because hyperloop was used to throw sand in the gears of modernized rail in the US. The X app idea is just lame, or, at best, a "Here's the real strategy!" distraction to be used when Twitter lurches to the next crisis, like interest payments or getting locked out of their building.
They have hundreds of thousands of customers and been growing for more than a decade, I don't think you can imply a lot from the 4 implementations you've seen.
> Boring tech club ftw

As a CTO, I couldn't agree more. For our internal product, we use 100% boring technologies. The most "modern" you'll find is a React SPA.

I sigh when clients want to go the microservices route for a team of just a few developers. When you want to use NextJs for their tables&forms app. When they choose to use Kubernates instead of a couple EC2 instances.

Don't get me wrong, these technologies are great for us because we can charge more for the wasted human time developing these overengineered solutions. But I always, for my peace of mind, try to talk them out of them. Sometimes works, sometimes doesn't, at the end of the day it's their money.

Hydrochloric acid: My hardware store sells 30% HCl as Spirits Of Salts, for removing limescale from toilet bowls. It's effective, unlike toilet bleach. It's nasty stuff, and if your seat-hinges are metallic, you risk corrosion. And remember to flush before you crap.

Sulphuric acid: No, hardware stores don't sell that here. You can get it from car batteries, and builders use the strong stuff for clearing drains. I have no idea how I could legally buy fuming sulphuric acid.

Nitric acid: Even less. Fuming nitric and sulphuric acid mixed gives you nitrating acid, which in turn is the gateway to nitrocellulose (and I suppose nitroglycerine), fulminate of mercury, and ghod knows what.

It's just as well that these latter two acids are restricted; if they weren't, I'm quite sure I'd have tried to make guncotton, and probably blown myself up.
Indeed, the frequencies get higher further away from the center of the FFT image with the center being the "DC" component of the signal. The brightness, as you note, correspond to the amplitude of a given frequency.

you can think of it as a polar plot where:
radius = frequency,
angle = angle (as in points along the horizontal direction in the FFT correspond to e.g. vertical stripes in the image),
brightness = power

There is an imaginary part to the FFT that contains the phase-shifts needed to add everything back up into the original image. You may have noticed that the "FFT of the image" is symmetric, so something else should be needed to compute the inverse.

The same reason why my clothes are utilitarian and I can just about cook cereal. I don't care.

Now, in my defence I don't go around belittling the arts of cooking and fashion. They are fully justified endeavours. I just choose not to indulge in them, I hone the mind instead. Of course, one might say that eating and dressing will is beneficial on several levels, but fashion is whimsical. People come and go. Only intellect remains.

But why do you think legislation should be the one forcing that choice on everyone, rather than the market allowing consumers to choose?

The issue isn't what we personally like or prefer for ourselves -- it's more about when we think it's legitimate to take away the right of businesses to experiment with business models, and of consumers to be free to enter into the tradeoffs they prefer.

Why shouldn't a consumer be allowed to agree to what you call "extremely invasive spying" in exchange for a free product, if they want to? As long as you're not signing away rights (e.g. you can't agree to sell yourself into slavery) or engaging in physical harm (e.g. food and safety regulations), then what's the moral basis for taking away choice?

After all, what you call "extremely invasive spying" other people might consider no big deal at all, in terms of their own personal data.
Somehow I missed a paragraph from the article and yeah, the books seem to be mostly evaluated as they come into the jail.
The imagined use-case for Pushup is the same niche that Rails, Django, and Flask apps occupy, which is a wide range but broadly I would describe as page-oriented, HTML-first, server-side frontends.

I started Pushup because I asked myself, I like programming in Go and think (like you) it's great for web backends - but what is holding it back from being a great full-stack web dev language or environment? net/http is a great building block, and html/template is solid, but I felt more was needed. Like opinionated project directory structure, for one. But also the world has changed since 2006 when Rails and Django debuted.

Obviously, we live in a world in which React and the SPA is seemingly dominant, but projects like htmx have recently shown that you can achieve modern UI/UX in the browser on a server-side app, which less JavaScript. BTW, more and more JavaScript frameworks, like Remix, are (re-)discovering the value of SSR.

I was also motivated to give an old-school mod_php feel of, just add a file and you automatically get a URL route. That's a nice developer experience but also good for long-term project maintenance.

Finally I was struck by this essay[1] about the demise of the "mildly dynamic" site. There is a wide diversity of types of sites and apps, from quick experiments and prototypes, small-to-medium sites of many kinds. But also since it's Go, I think it could scale up on performance to large-scale sites, and as a static binary, be nicely suited to edge apps like fly.io.

I think the push to video and away from text is a net failure for accessibility and usability, at least for reference use cases.

My example: as a woodworker, I'm often curious about the details of a particular joint or the usage of a particular tool. The great amount of content on YouTube is helpful, but it's incredibly inefficient to have to seek through a bunch of filler or unrelated content to get the answer I need.

Of course, that's "increased engagement" so I'm not surprised it's what is commercially more viable.
That'd imply it's okay to put smokers in cages without cigarettes until they've stopped smoking and I'd suggest that that's fucking insane. We've discovered another dimension!

While I agree, I have found ChatGPT to be REALLY awful at symbolism because so many people are as well. It gives popular responses rather than most correct responses. As we have seen from politics, popular often times isn't correct.

An example of this is music:

ChatGPT responds to "What is the meaning of The Postal Service's The District Sleeps Alone Tonight?"
With:
"The meaning of "The District Sleeps Alone Tonight" by The Postal Service is open to interpretation, as the lyrics are somewhat vague and abstract. However, the song appears to be about the feeling of isolation and disconnection that can come from living in a big city. The lyrics reference the city as a "church" that "wraps [the narrator] in its twilight," and speaks of the planes flying overhead and their passengers "waving goodbye/ To all of their yesterdays." This could be seen as a metaphor for the transitory and fleeting nature of city life, with people constantly coming and going and not forming deep connections. The song may also be about the narrator's own sense of loneliness and longing for connection in the midst of the bustle and noise of the city."

There's two issues with this response:
1. The song is about the weird feeling of how places change with context, in this case it is about the context of a breakup and feeling out of place where you used to feel at home.

But there is a bit of a bigger issue....
2. Those lines ARE NOT IN THE SONG. lol.

What this shows is clean readable responses that are oftentimes extrapolation of a thread or idea to levels not reasonably verifiable. Like how Facebook is/was tuned for giving more and more isolated extreme content, ChatGPT is tuned to follow threads and bits of information to extreme levels and confidence.

Micro-meteors; frictional wear and tear from normal use; proton ablation from the solar wind[0].

I'd assume we couldn't even get to that scale without solving vandalism, war, and insanity, but if not, then over the scale of a million years there will be twenty thousand space-Victorians and space-Taliban having space-Jihads against space-Buddha- and space-Baphomet-statues. I dread to think what the K2 version of the deliberate destruction and death of WW1 and WW2 would be like.

Likewise industrial accidents (space Chernobyl?), but if the big ones aren't solved there's a significant chance of a Kessler cascade rather than just, say, small incidents destroying 1% of the habitats every millennia[1].

This is excellent, thank you. I was under the impression that the compressed instructions set required a dedicated compiler switch, and counted a number of instructions instead. Now that «X is 18% smaller than Y» is quantified, there is the circumstantial evidence, and it gives a clearer idea of the differences between two ISA's. Yet, it does not validate the absolutist and unquantifiable «awful code density» statement.

I have also noted that compressed and uncompressed instructions are unevenly interleaved in the generated code, and occur in random sequences, i.e. addresses 0x10a60 ÷ 0x10a72 follow the 16-32-16-16-16-16-32-16 bit sequence whereas most other instructions follow 16-32 bit or 16-32-32 / 16-16-32 bit sequences. I wonder what performance penalty for the instruction decoding unit in hi-perf RISC-V cores is going to be for compressed vs uncompressed instructions code especially if the instruction being decoded spills over into the next L1 i-cache line (or, worse, into another memory page). RISC architectures are generally averse to misaligned memory access.
Just like with anything else, exit route is a function of time and budget and the migration cost is always proportional to the previous customization effort. If you pay 100k per year in license costs and spent 200-300k in 2-3 years to build current setup, you may need another 0.5-1M to get off this hook and jump to another one (which will be hard to pick). I doubt anyone seriously considers this scenario, because risks are too low and rewards are too high (it is a really good product, for which in many scenarios it is hard to find cost-efficient alternative).
I was commenting on the HN rules because I sometimes forget them.
So burning wood is about 4kWh/Kg

Batteries top out at about 3kWh/kg

So strictly speaking you're better off just burning the wood, although there are inefficiencies turning the wood to electricity so if that's what you want the wood battery is probably better.

Cost wise, the cost of a sapling plus axe is less than batteries plus solar panel. But if you want electricity you'd need a generator plus steam engine / wood gasifier, which bring them to around about par.

This really seems like php. I also think that mixing UI with logic is a recipe for disaster and there is already php (and several others?) for that. I suppose the creators of such a thing have a decent knowledge of compilers and related domains, knowledge which really seems wasted on a project like this.
Another concrete example of the conflict is classical vs quantum physics which is nearly exclusively taught as the historical story of the quantum revolution or whatever you call it around 1900.

It would be trivial to skip the historical story and just "yo here's a FET transistor, a solar cell, and a vacuum tube, and the math just works, so get used to it" but nobody is ever taught that way.

Would be interesting for someone to attempt to write a non-historical physics textbook.

On the other hand, in IT, this style of learning is considered normal. "This is how the kool kids do things today. The past does not matter and probably didn't exist anyway. The end."

The biggest risk with such software as a web framework is security exploits. The nuances of the HTML escaping dance are subtle and hard to get right.
