I'm guessing you're asking because of this submission (yours) from a little while ago that's somehow even off the Ask page, not just the front page, despite having a good amount of active discussion.

Ask HN seems to be more sensitive to two things than other discussions:

1. Comment:Score ratio. The ratio of comments to points is 3:1, 69 comments and 23 points as I write this. None of the discussion threads are very deep, but when a discussion has a lot of comments but not a lot of points it tends to get moderated (automatically, not by dang & co.) down faster. This probably relates to the flame war detection, though I've seen that kick in more often when comment threads get very deep and more linear than branching.

2. Flags. When Ask HN submissions get flagged, they move down faster than article submissions.

The Parekh discussion has a high score and a high comment count, so (1) is not applicable to it (more comments than points, but more like 4:3 so not over whatever the threshold may be). I have no idea if it was flagged, but if it was since it had active discussion the mods can turn off flags (as it impacts rankings) on a submission by submission basis.

Wokwi seems to be the most popular Arduino-based one.

I'm not a huge fan of simulation for cases like this. The arduino forums are full of "it worked in simulation, but not on my breadboard..." complaints.

Also, simulation won't teach you not to connect a 10ohm resistor across a 12V supply and then touch it. Or that capacitors may explode when connected in reverse polarity, or just how to be careful in general. There's a lot of stuff that should become second nature, but you'll only learn by connecting physical circuits.

Thanks. If I’m understanding you here, you use both Kagi and Calude for general search?

Assuming you default with Kagi, but switch to Claude (API? Raycast?) for search if you don’t like the results you get?

Perplexity I’ve found incredibly powerful for search as it’s fast, and I love being able to toggle “Social” as a source quickly before sending an inquiry off - in case I want opinions vs sources.

That said, I have found it on occasion being lackluster a handful of times on the first go, so I have to manually switch the model from the default “Best” mode (which selects the best model for the task) - to specifically Gemini, o3 etc. to get a better result.

If you can't judge that funding war criminals is a wrong action, you should reconsider your ability to do so morally

Perhaps I shouldn't be surprised, startup founders aren't exactly known for putting anything else above money and their ideas, particularly actual human well-being.

Consider that you, too, will have to live in the world that you help create, including the consequences of "a mere 2%"

This would certainly be news to me as well. Packet capture (even local) has historically required superuser perms, but I'm not up to speed on how MacOS permissions work in this regard since the launch of System/Network Extensions.

After writing the above, I've just reviewed [0] - as much as I could in 5 minutes - and as far as I can tell it confirms our understanding. To do packet filtering or interception or reading, you'd need to do [1].

GSP’s trainer Firas Zahabi prescribes to this. I remember his mentioning this in a Rogan podcast. His philosophy to training is minimal to 0 pain/soreness.

Instead of doing pull ups till you drop start with 1 and do it daily. I started running after a long time. I’m 49. I work out with weights but needed mild cardio. I started with 0.25 m run / 0.25 m walk cadence. I can easily do that for 5-6 miles and keep my heart rate below 165.

Bottom line is - take it easy. The goal is to burn calories, stay mobile and not get injured or sore.

I never said it was a perfect system or that we are morally pure, but it is the best one we have come up with so far. It has improved the human condition greatly, albeit in fits and starts. Western liberal states broadly have greater civil rights and have reduced poverty more than any other type of system in history. Your ideal (I think, you aren't very clear) of enlightened anarchism doesn't exist in any human society. Any short period of anarchy that has happened has been a shit show (i.e. France throughout the 1790s) that gets resolved by the most power hungry and murderous psychopaths possible.

Yup, keylogger defense. I've seen a system with a full virtual keyboard to let you type anything without hitting a key--explicitly as a security measure. Fixed keyboard, though, I've never seen one with randomized targets. Capturing everything would be an awful lot of data for malware to export so I don't think screen capture is much of a risk.

Even what you just pasted is wrong. And it would give a confusing error if you used it. Try "sudo apt install vim \ make" to see.

It's the kinda thing an experienced engineer wouldn't have that much trouble with, but you should be able to recognize how much experiential knowledge is required to compile a complex C code base and what kinda dumb stuff can go wrong.

You probably don't need to do much of the stuff on that page to build, but "What is dnf?", "Is the pre-commit hook important?", "Do I need cpython?", "What's an ABI dump?" are questions many people will the wrestling with while reading.

Re: ant, make that two of us.

I use Gradle these days since IntelliJ doesn't work well with ant; but when I want to precisely control how a build is done and produce exactly the build products I want, I use ant. It's stable, it's well-documented, and I never need to guess what it's doing because it's doing what I told it to do.

I like the idea of an opinionated build tool; but I'm not happy with any of the ones I've tried.

> Well, all the stuff you listed is pretty much why it's great. It's almost the simplest thing that could possibly work

And that's all well and good, did recognize that, but then isn't it a bit disingenuous to present it as some sort of "real" solution in a thread about a communications technology that aims to cover much more? It's like arguing that Prometheus is the be-all end-all of monitoring, even though the remaining concerns still remain, and are just shoved aside to be some adjacent solution's problem.

> Lack of history means you aren't legally obligated to moderate history (because there is no history)

Is that actually right? Feels pretty suspect to me, you have to hold onto the data at least a little bit to transmit it to all connected clients, being a client-server protocol. I don't think this passes by the courts, not any more than holding onto a few dozen or a few minutes of logs in a non-persistent fashion (i.e. in-memory only) would.

Very easy to set up (without the Docker nonsense, it's just a binary that is trivial to build), but the real work was in maintaining it. After the third case of database table inconsistencies from joining large public rooms (or perhaps from upgrading it, or a combination) I regretfully had to give up on it. It was time consuming to find out the table structure being used and how to manually correct the data so that it would start again. People were generally helpful on irc but it's just not fun work and feels a bit unnecessary.

the slot machine is apt. insert tokens, pull lever, ALMOST get a reward. Think: I can start over, manually, or pull the lever again. Maybe I'll get a prize if I pull it again...

and of course, you pay whether the slot machine gives a prize or not. Between the slot machine psychological effect and sunk cost fallacy I have a very hard time believing the anecdotes -- and my own experiences -- with paid LLMs.

Often I say, I'd be way more willing to use and trust and pay for these things if I got my money back for output that is false.

This is called an FCU (fan coil unit) and is common in Asia. It consists of a high efficiency central chiller run by building management, and pipes to bring coolant to each unit. Then in each unit there is a heat exchange coil with a fan to blow the room air through the coil. Hence fan coil unit.

The advantages of this system are that the only sound in the unit is the fan, and air is not circulated between units. The disadvantage is that building management can turn off A/C centrally if they want to save money.

For some reason Americans are slow to pick up HVAC innovations that are common elsewhere: heat pumps, split-system air conditioners, FCU, etc. I guess it is because energy is cheap to them and they don't mind noise.

Another commenter already mentioned that they did not actually use o3 in the study.

Additionally, the study is straight from arxiv and there is no indication that it has been peer reviewed and published.

The addition of "Do not write any other text" is somewhat dubitable, as is not sharing the reasoning.

When I recreated this, the female outcome was $430000. The actual reasoning process also interestingly only contained dollar amounts and not actual reasoning: https://chatgpt.com/share/6879412b-0328-800a-8982-caab82505f...

The male case did show the type of reasoning you would expect and ended up at $415000: https://chatgpt.com/share/68794153-1264-800a-8b00-5bb6752ae2...

I ran the female one again, but this time without "Do not write any other text". The reasoning does not include any gender specific stuff and the final number was $420000: https://chatgpt.com/share/68794202-70d0-800a-9f17-ac033dc5e1...

> About politically-touched questions like whether I should rather use an EU-made AI like the one this topic is about, or use one from the already much of the software-world dominating US vendor, I don't care at this point, because I'm not yet creating any significant dependencies. I am glad to see it happening though (as an EU country citizen).

Another nice thing about waiting a bit—one can see how much (if any) the EU models get from paying the “do things somewhat ethically” price. I suspect it won’t be much of a penalty.

Every former DoD engineer I've spoken to has worked pretty extensively in Ada. From the Phalanx, to the F-15/F-16. C++ didn't start becoming popular in those domains until the mid-00s. The first fighter jet to use it extensively was the the F-35[1], which many of the engineers attribute to it's early issues[2]; not because C++ was bad, but because so much well-tested and hardened code had to be replaced.

So, wherever these waivers were, they certainly weren't in those spaces.

Right but there were so few people using operator to buy stuff that it's easier to just block ~ all data center ip addresses. If this becomes a "thing" (remains to be seen, for sure) then that becomes a significant revenue stream you're giving up on. Companies don't block bots because they're Speciesist, it's bec usually bots cost them money - if that changes, I assume they'll allow known chatgpt-agent ip addrs

California almost had such a system. NPR's Planet money did a great episode on this called Tax Hero: https://www.npr.org/sections/money/2019/04/03/709656642/epis...

Description below is from the podcast episode page:

> Back in 2005, a group in California decided we could make filing taxes dramatically simpler in the US as well. Lots of Americans could receive tax forms in the mail that were pre-filled out by the government. All they'd need to do is check for errors and send the forms back in.

> Joseph Bankman, a law professor at Stanford, thought this was such a no-brainer, that he offered to test out the idea with some California taxpayers. It turned out to be a huge success. Other states thought about using the plan. Even California's governor at the time, Arnold Schwarzenegger, supported it.

> Bankman thought getting ReadyReturn through the California legislature would be smooth sailing. He was wrong.

> Uber has signed a multibillion-dollar deal to buy its first robotaxi fleet from Lucid, which will see the Californian electric-vehicle maker partner with self-driving start-up Nuro and receive an injection of fresh capital.

> Customised versions of Lucid’s Gravity SUV, using technology from Nuro, will be rolled out over a six-year period, starting in an unannounced big US city next year.

This is an investment by Uber in Lucid, and as a side-effect they are purchasing "at least 20,000" vehicles from Lucid.

Interesting bit is if Lucid is a robotaxi already, then what is the technology that Nuro is providing? Best reading is Lucid's car is a platform, but doesnt have any intelligence itself (OEM) and Nuro is the operating system.

> There's also the accessibility factor. Many people become farsighted later in life. It's much easier to see things on a big phone, especially with increased zoom. (I see this all of the time when I fly.)

Or for those of us with higher end myopia whose lenses effectively “shrink” everything they see. I’m -6.75 in each eye and my glasses make my everything seem significantly smaller than it is.

Sometimes I look at my phone or monitor without my glasses and am momentarily shocked at how large they seem and then saddened when I put them back on.

But wouldn’t a consequence of failing to err on the side of caution and “orthodoxy” mean a proliferation of junk and pseudoscience? We already had that problem now but the change you are proposing seems to put a foot on the gas for those issues.

Sure, some valid papers get rejected, but how many bad papers are also rejected? How would it affect the wider scientific community if 1 additional good paper is “approved” and also 100 bad papers? Does good science still make it through eventually, or are these rejected papers losing valuable insights “forever”? What kind of damage can a bad paper cause and how often?

It just seems like it isn’t as clear cut as “the current system is flawed…and the alternative is objectively better” to me.

Well yeah, because the agent is so much cheaper and faster than a human that you can eat the cost of the mistakes and everything that comes with them and still come out way ahead. No, of course that doesn't work in aircraft manufacturing or medicine or coding or many other scenarios that get tossed around on HN, but it does work in a lot of others.

this is a terrible response.

Where are your customers? Predominantly the West, likely the US? This is not a question of "geopolitical judgement" but rather of funding a regime that illegally invaded another country, one that is responsible for a lot of cyber crime, one that oppresses its own people and one that directly uses misinformation to sow chaos in other countries.

Apply this same argument to North Korea or Iran. Assuming that either contributed meaningfully to the quality of your search results, would you be comfortable sending money to companies based in Iran or North Korea?

You can hide behind your technocratic arguments for a while. Look to Google and Facebook to see where that ends.

I have inside knowledge (that I'm not trading on) of multiple publicly listed companies with "every feature is AI powered or it doesn't ship" policies that are being applied to their entire product or major parts of their product. Those policies come from execs who are primarily informed by science fiction and FOMO, not by an understanding of the available tools.

AI is great when it's the right tool. But the rate at which features are shipping at these companies is plummeting because so many features would be cheaper, easier, and better without AI. It feels like self-gaslighting on a scale that I haven't seen since the dot com days. And I see engineers and their managers struggling to maintain their sanity as they try to improve their products within the constraints of these policies.

As somebody who has been through various forms of psychotherapy, knows trained professional psychotherapists, knows highly educated personell in the relevant educational institutions, etc. the very mild summary that I think when reading what to my mind is a generalized statements like "Whole schools, e.g. psychotherapy, are possibly net dangerous." is:

Also: Psychotherapy is not a school but is divided in many different schools.

Sure, but I still think this is preferable to sending the password in clear text even over HTTPS. You're trusting the server doesn't do anything with the password and immediately hashes it, but it might not. It might store it, or even if it doesn't, your password will stick around in RAM for an indeterminate amount of time.

If the server is compromised in any way, passwords could be exfiltrated. Companies are, sometimes, wildly incompetent. Zoom historically stored private keys on the same server as their "encrypted" data. I would not be surprised if your password is just stored for "convenience" or some other bullshit reason and just waiting to be breached.

I think there could be a market for a small reliable Android phone. The main issue is that it'd take years to build up a model's reputation and it'd have to be reasonably low price.

As it stands the kind of people who want a smaller phone almost by definition need to be a bit savvier than the market in general to know such a thing still exists and along with that will have greater skepticism towards Android phones having any kind of post market support.

It'd basically have to come from Samsung to hit the all the price/quality/trust requirements. Feel like they've already got a lot of the pieces there with their corporate targeted XCover range just shrink them down a bit.

I think that what most people mean is that with a self-taught engineer, you have no way of knowing whether they have the foundations. It's going to be much more common with self-taught engineers than with formally-educated ones to have areas of surpassing brilliance, and areas where they don't know their arse from their elbow, and no easy way to predict what those will be until you get to know the specific engineer.

With formally-educated software engineers, so long as the school they got their degree at is a reputable one with a decent program, you can be reasonably confident that they'll have a solid foundation, and if you're familiar with the institution you may even know what their strengths and weaknesses are likely to be.

This article lavishes well-deserved praise on the intentions behind Reading Rainbow. I know I loved the show as a kid.

But it seems like childhood reading scores were pretty much flat between 1983 and 2006, when the show was on the air: they only varied by 10-15 points on a 500 point scale[1], and there was no clear upward trend, it just sort of fluctuated. Reading for pleasure has never been lower among kids, either[2]. It doesn't seem to me that the mission of the show was achieved, if the mission was to make children read more books, and understand them more.

Ultimately I think it ended up just being a pleasurable way to have kids get distracted by a friendly, positive TV show. My guess is that if you want to improve reading scores and habits, parents have to do more than just turn the dial to PBS.
