TDS is just Total Dissolved Solids. What solids though you don't know and you could be adding carbon while removing others which is likely the case.

Also those dinky little TDS meters don't even measure TDS. They measure electrical conductivity and with a little math they use the EC as a proxy for TDS. It's typically only calibrated to one specific ion, others will be off by some factor. Also keep in mind TDS is expressed in PPM as CaCO3.
So basically the "middle ground fallacy" distilled to its purest form as the overarching moderation guidelines for this website? I have been a hackernews reader for almost 15 years and I remember when this very much was not the case. The main goal was TRUTH and CURIOSITY.

now the main goal seems to be coddling the most inane and lukewarm minds imaginable. More concerned "politeness" and "civility"

They argue that 1+1=5 while I say no FUCK OFF 1+1=2 then the moderator says now now let's be civil here and meet in the middle at 1+1=3 ....no ..fuck off... 1+1=2

And when it comes to REAL engineering or geopolitics or medicine or government policy with people's lives on the line ...the TRUTH matters more than being polite.
Pretty much everyone but the actual students agree that would be better. We can't do that since the students typically refuse to do the necessary prep.

If I give you a function "f(x) := 3 * x", is it really that useful to talk about it as a container of the natural numbers?

The reverse though is useful, a container looks like a function that takes one or more indices and returns a value or element.
Just like "the science says" (but unlike "the English say" ;) ).
I did a bare metal to Docker container migration in about 30 minutes a couple of weeks ago. It’s not a very complicated setup, with few surprises, and this system admin appreciates that.

Sure stopping your kids having access to youtube and tiktok is a good thing, a great thing even. A soul mirror is a dangerous thing for an impressionable mind.

But it feels like none of this post is actually about protecting kids, its more about showing off how cultured the author is. Which is fun when seeing a mishmash of french/english 18th century furniture with incorrectly hung paintings.

Look social media is corrosive. There is a reason why the skill of an editor makes or breaks a media company. There is no editor in social media, only you. But to mix up anti-social media with a half baked aesthetic is just bollocks.

The irony is, the aesthetic is an analogue, its an analogue of an english/french town house. As remembered by someone who goes "what image does this project" rather than "do I like it"

The artwork on the walls is not going to make up for being raised by a succession of nannies, or going to a school surrounded by exceptionally rich and emotionally damaged kids.

If you want to raise your kids in an "analogue world" You need to be there. Otherwise you're just outsourcing your kids world view to zuckerberg et al.
While true, if the earth stopped rotating the sun would also stop being "evenly" distributed around the globe, which would affect wind patterns a lot
I answered the exfiltration likelihood in a sibling thread. The summary is that spies are very rare and it is not a likely explanation. Keeping the Bayesian hat on we can pretty much rule out aliens. We have never witnessed an alien abduction, so the chances of this being an alien abduction is actually infinitely smaller than exfiltration.

We can set the same prior probability to all the possibilities, that is fine. But given the evidence the posterior for alien abduction is very close to 0, if not just simply 0.

Given the recent pattern of behavior from the US government, we have seen quite a few people disappeared. The posterior for US government involvement is IMO much higher than exfiltration. That said, no government involvement is higher still (and is actually the hypothesis favored by Occam’s Razor).
> That probably isn't correct given that IU has scrubbed him from their web pages. That alone makes this look like disappearing him and his wife.

Why?

As a possible explanation: Wang disappears suddenly and without warning. The university investigates and in the course of the investigation discovers that he was working as a spy for the PRC for the past 20 years while employed with them. They freak out, knowing that the current political climate (especially in their state) is one where they can't afford to become known as that school that harbored a Chinese spy, so they rush to try to keep everything under wraps.

Unfortunately, they have to report what they found to the FBI, which proceeds to very un-subtley raid Wang's homes, drawing media attention and possibly triggering the firestorm they hoped to avoid.

As with anything at this stage, this story is entirely supposition, but it does explain the known facts, and it explains them better than any other explanation I've seen floated in this thread.
The "center" in that means a collaborative project with multiple PIs instead of a grant used to fund a single lab. The total funding for the project in the current funding cycle seems to be ~$10 million over 5 years: https://www.nsf.gov/awardsearch/simpleSearchResult?queryText...

> It is a transaction.

That is a purely rational take, but people are seldom rational. My pet theory is that inertia is a huge reason why people choose college. Majority of people who go to college do it as a continuation of 10-12 years of continuous schooling (or partying). As they climb educational or social hierarchies they are constantly reminded that college is a next step. Thus going to college feels far more familiar and less scary than joining the workforce. Thus, going to college is a default choice for many.

After the gut decision is made it can be wrapped into whatever rational argument.

About the short projects. I am a high school senior, and I sometimes jump around between projects / don't finish them because I sometimes struggle to see the point in finishing them. The only projects I can complete are ones where I can see the point of them and how they will be used.
That's not close to accurate. It was never ok for HN users to tell each other to fuck off, and the purpose of the site is just the same as it always was. As for truth: people telling each other to fuck off does nothing in service of truth. I recommend this old pg quote to you:

Comments should be written in the spirit of colleagues cooperating in good faith to figure out the truth about something, not politicians trying to ridicule and misrepresent the other side.

This is a good question. The other question that I haven't yet seen the answer for is how anyone will make money off of an AGI, if such a thing is actually feasible in the near term. As it is the business model for just LLMs and generative models in general seems flimsy.
Building Based Security (https://www.basedsec.io), a startup in the zero trust/identity space creating immovable, attestable, hardware backed identities that can be used for strong and continuous authentication but not moved from the device. We can guarantee the user and the device are known, the user is assigned the device they are using, and characteristics of the identity matches the defined policy. The initial product offering is tied to GitHub/GitLab, offering secure authentication for git over ssh operations with plans to expand to general ssh access and additional systems with pluggable access control.

I think TFA is unfair wrt pandoc's dependencies. I'm not sure if the listed "ecosystem" is what you need to build pandoc from source, or just the result of shitty packaging of pandoc from the OS package maintainers.

For the record, the .deb download from [1] gives you a 146MB statically linked pandoc executable that depends only on libc6 (>= 2.13), libgmp10, zlib1g (>= 1:1.1.4).

If you're graduating with a CS degree, you just have to follow the same advice as for new CS grads.

I'd check out resources like csprimer and Math Academy and Frontend Masters to get a solid foundation. After taking an algorithms course, you can start productively studying leetcode on sites like neetcode.
There's a lot to be said for how abuse was portrayed in Twin Peaks. Many survivors of abuse have praised the show and it's film counterpart for their honest portrayal. Sheryl Lee, the actress who portrayed Laura Palmer, has highlighted her positive interactions with survivors in numerous interviews. It's a hard watch, but it's an honest watch, and empathetic at its core.

You're focusing on the fact that such abuse is shown, without digging any deeper into why it's shown, and in what context - context that you are inherently ignorant to by your own admission of never having seen Blue Velvet. I have, so I know of what I speak.

And to your flip response about, "Enjoy your Insta", I don't. I stay far away. Once again you seem to be making assumptions about people (and casting aspersions towards them based on said assumptions) and things based on surface level interactions, the opposite of trying to be compassionate.
Same here in NZ, although I think our peers are biased. Ranging from home-schooled home-birthers with 0 screen time to hybrid schoolers with perhaps 1 hour per week screen time (for toddler age).

Yes - it’s a cognitive pitfall humans are prone to. You can see it with any group membership - here on HN, how many comments have we seen where someone is defensive about legitimate criticism about their favorite programming language or style – but it can be especially bad with politics because it can be weaponized by people acting in bad faith with significantly more negative consequences.

The West supported an brutal military dictatorship in South Korea for decades. South Korean democracy is the result of internal struggle by the South Korean people.

New York’s public system is fully funded. It’s pretty easy… you just fund it.

Social Security is a pretty amazing system. Inflation and a fixed cap for taxation has led to a relatively minor revenue shortfall, 90s welfare reform pushing welfare recipients to SS Disabilty, and a few other factors driving the spend side higher. We also tax those benefits for many, and fund Medicare through premium payments.

You need to raise taxes and push out the the cash flow issue a decade. Then demographic trends fix it. Instead, we’re exploring this cruel & destructive approach, which will trigger a depression in the end. Between housing defaults, implosion of medical facilities as Medicare funding gets slashed, and god knows what else, we’re damaging the country.

A chromebox mounted behind the monitor did the trick for me. Haven't had an emergency wipe/reinstall in years. Also, a tablet with keyboard takes some of the pressure off having a "computer" and you can go with iOS or Android depending on what phone they use.
Sure, there were people who created those systems, but most didn't really get a choice in how it happened. Singapore seems like a pretty good example of that, too?
>Property tax is not land value tax

A lot of property tax is land value tax, especially in rural areas where there are little to no improvements.

>No, it specifically makes sprawl very expensive relative to density

Not at all, it contributes to sprawl. Cheaper land is farther out of the city centers, so it lessens the cost of purchasing real estate farther and farther out.
It appears to have taken San Jose’s place, from a combination of San Jose shrinking and Fort Worth growing.

My strategy is generally to have a back and forward on the requirements with the LLM for 3/4 prompts, then get it write a summary, and then a plan. Then get it to convert the plan to a low level todo list and write it to TODO.md.

Then I get it to go through each section of the todo list and check each item off as it completes it. Generally results in completed tasks that stay on track but also means that I can stop half way through and go back to the tasks without having to prompt from the start again.

One issue with that is that you can write Flatmap in a way that doesn't obey the Monad axioms. And once you write out what it means to be 'correctly' flatmappable you've recreated the Monad axioms.

Though it would help if more people were aware that a 'nice' way to 'unnest' a functor (F F x -> F x) is really all that it takes to have a Monad.

I empathize with this. I went to one of those “top tier” universities and had a handful of classes where I regretted being one of the few (fewer than 10) goody good students who attended lecture, and subsequently fell asleep anyway. Over time, I realized that universities like these primarily prioritize faculty who can attract grant dollars over those who are excellent teachers.

But that said, I don’t believe this author is complaining that students generally don’t attend lecture. They’re complaining that absenteeism has increased, implying that it has increased substantially recently. And that this sudden increase in the delta is a cause for concern.
But apparently you’re crazy if you say the US is now a dictatorship and you won’t get a fair election in 4 years.
Even starting out, with used/refurbed hardware you can put a lot of compute power into a colocation facility for very little money.
Very cool. Does the dynamic instrumentation handle JIT emitted code?
Are you suggesting that it isn't helpful or useful to speculate that he was an undercover FBI agent working to infiltrate US-based dark web crypto gangs and that the University's actions tipped off the gangs? So when he went missing the FBI kicked into high gear? Just making stuff up like that doesn't provide clarity?
Given what the author says about student behavior, this would only result in 99% of them failing the course.

This is excellent. It's just what i needed cuz it has always been bugging me that the scope of responses is confined to what the prompt explicitly defines. The LLM doesn't debate your reasoning and ideas, just answers what you're asking for. Thanks, gonna try this out.
This sounds really cool. Do you have any guides or notes on how to set this up? I've been looking for something to dive into for LLM and MCP.
No mention of LATCH theory? (Location, Alphabet, Time, Category, and Hierarchy)

Oddly, no matter how they are organized, their indices will always be a hierarchy (tree).

Personally, I think human brains just have a categorization approach that is built into our brains as hierarchy, so while other methods are definitely useful, they are an add-on, not a replacement.
ESA has had loads of orbital launches. Arianespace is a French company and the world's first commercial space launch co. Not sure it's reasonable to discount EU as stagnated.

There are few places in EU that make sense to launch from - the ideal launch site is from the equator, from land, with an empty ocean to the East to launch over. Look at the EU geographically and you can see why the European launches would chose a non EU site.

Now with the US and Russia both becoming poor candidates geopolitically, I suppose it makes sense to explore local options, even if they're less efficient/safe/convenient.
In the 2nd study that shows correlation between fluoride and lower IQ in children, the water had twice as much fluoride as the recommended amount in the US (1.5 mg/L vs 0.7 mg/L).
In fairness, there was no public evidence of the Nazi death camps up until they decided to turn the prison camps into that at the Wannsee Conference either.

It was only in retrospect that we learned the true horror of the Holocaust.

Given that period of history, and how it brought the world to the brink, any patterning closely similar to that (which we are seeing today) these things should be considered happening until it can be proven otherwise.

Complacency and a lack of accountability in the moment is how these things happen, and turn good people to sloth.

Saying "Trust us", just isn't going to cut it given the existing state of no credibility that is a consequence of over a half century of bad acting and abuse of authority, and the trusted news initiative (which is not trustable).

It is hard for me to distinguish between the functional simplicity of desktop computing in that era, with the overall excitement that the explosion of connectivity brought to the world. The internet was a lot of fun and had so many surprising corners. Practically all of it was personal, niche, or experimental content for awhile.

I wonder if Windows 9X was really all that exceptional, or if it was just what people remember driving with as they navigated the new world.

The best modern equivalent to that desktop paradigm I've found is LXQt, although when I use it I find I kind of miss some of the accouterments of the modern desktops.

I enjoyed reading this. Admittedly I'm very new to the activity pub protocol, but it's hard to grasp at first how this leak actually occurs.

I read this part of the activity pub spec and I think I get it, but not completely. So it is really up to the activity pub server implementation to strip the bto/bcc audience fields and do the "right thing" in order to preserve privacy? Could anyone shed some light on this?

Nothing in your response outlined a possibility that was not in 1 of the 2 options given by my own government.

I don't give a fuck what the French or Europeans think. I am holding my own government accountable to what are ostensibly the values we share(freedom of speech and national security) and finding them lacking. It requires zero input from the French scientist in question for me to be upset with the situation

And no, I don't need a timeline to understand this because my problem with the government's own explanation does not have a time based component
Nah...exfiltration does sound like the most likely scenario (to anyone with commonsense).
Not really doing that with my kids. It’s important to nudge them in the right direction but that’s about it. Any absolutist things are not helpful as they build resentment and resistance. Constructive discussions and teaching them to reflect is important.

I mean my youngest got into Roblox for a bit (talking weeks). Yeah fine with that, with one eye open. One day someone stole all her shit and her friend was an asshole on the same day. Sat down and talked about virtual items and grinding games and life generally. She never touched it again!
