I would say it's pretty gentle. Most 3D printers these days perform very well out of the box, and there's tons of online stl files to print stuff and get a feel for your printer. After that designing your own things can be in any CAD tool or even a modeling tool like Blender. Fusion 360 is very approachable IMO. For prusa printers, prusaslicer is also serviceable for just putting some primitives together to make objects. After that it's just tweaking stuff as you see things that can be improved. Since smaller objects can be printed relatively fast, it's super quick to see what tweaks do in the real world.

> Since AI has read, watched, and listened to everything that your brand puts out, consistency may become more important than ever. “Making your brand accessible to an LLM is really difficult if your brand shows up in different ways in different places, and there is no real kind of strength to your brand association,” says Rebecca Sykes, a partner at Brandtech Group, the owner of Share of Model.

So now we have to do LLM optimization as we did SEO optimization in the past? No thanks.

> Is it just me or are we heading into a period of explosion of software done, but also a massive drop of its quality? Not uniformly, just a bit of chaotic spread

I think we are, especially with executives mandating the use LLMs use and expecting it to massively reduce costs and increase output.

For the most part they don't actually seem to care that much about software quality, and tend to push to decrease quality at every opportunity.

I mean the best that this thing can be is some sort of pin or remote the size of an iPod shuffle that you speak to and speak back to you and has a camera right I mean, how attractive can you really make that? That doesn’t sound like the most amazing product the world has ever seen to me.

You know does sound cool? Xreal glasses with whatever the maximum FOV can be shoved into the design of conventional glasses with some cameras and speakers. And that let me continue to connect to whatever device I want.

My old Oculus Quest is filled with software that doesn’t work anymore.

AI that doesn’t interact with the world or websites or apps is boring.

when you say "from the US" can you explain exactly what you mean? and what sources you're drawing from to show that the fentanyl is coming "from the US" into Canada? I realize it sounds like i'm incredulous, but it's only because the US doesn't manufacture fentanyl. Canada does. Mexico does.

But alright, i guess people import it to the US to illegally traffic it back north. and somehow that makes a majority of the traffic! never stop learning, that's what i always say.

For two reasons:

1. I don't want to stay in a hostel. See below for more on this; but, hostels, at least the ones I have researched, have bunk rooms and shared facilities. Hard pass for me.

2. I don't like sharing a bedroom and, especially, a bathroom in someone's home when they may be there. There's simply a different level of security (potentially false, I understand) in a hotel vs a rented room in a house.

Every time I read a study that reports animals being smarter than we thought, I cannot help but think that this is obvious.

We humans are animals, nothing less, nothing more. We are animals with big brains, sure, but nothing of importance sets us apart from other animals.

To me, this whole idea of “human exceptionalism” has simply no plausibility, both from a biological and a philosophical standpoint.

A lot of news - arguably the majority - involves articles that are as bad as the headlines. If only the headlines were a problem, we'd be in great shape. The lack of effort is as bad as the bias.

The author's effort to clarify things is commendable, and yet, if anything, this article has a bad headline... but for the best reason, because it's more informative and specific than I expected.

> When I see comments like "Magit is the only thing that keeps me from leaving Emacs," I honestly wonder what they're going to miss.

The "killer feature" is how it makes git feel like a natural extension of text editing rather than a separate tool. Other git UIs exist, but none integrate the "edit-review-commit" cycle as seamlessly. It's less about any single feature and more about how it transforms git from something you "switch to" into something that's just... there.

A huge part of what makes Magit special - it's not just a UI, it's a complete git API for Emacs - Magit is a library, not only I can easily extend Magit's own functionality, I can just call its functions, advice them, etc.

For example: If I want in my tab (there's tab-bar-mode in Emacs) some git-based info, I can easily do it. Or I can hook into magit-post-commit-hook to trigger custom actions. This composability is impossible with standalone git clients. You're not just using a git interface - you're programming with git as a first-class citizen in your editor. Other tools give you a UI; Magit gives you building blocks.

There are integrations in Emacs that Magit author and maintainers never even thought about initially. Like for example in Dired, where you'd be listing directories, you can mark some files and dirs, and stage those files or show the git log pertaining only marked items.

But again, it's not so much about features that already exist in Magit, but the way how one can easily extend things to add features that are not there - and there are tons of examples - note-taking workflows (where using Org-roam/Denote one can stage specific thoughts from their daily notes, creating atomic commits of ideas); literate devops (where you keep tf/ansible scripts in Org-mode src blocks and commit directly from the same document); academic writing (e.g., with LLM integration); time tracking (where people hook to magit-post-comit to automatically log time entries); config management (where you use magit's cherry-pick to selectively sync specific configs between work/personal machines), etc., etc.

I dunno.

Spend a few hours apologizing for something that was wrong or users found offensive. Have a panic at 9pm one night when you find the password reset system has a bug in it and lets you reset somebodies password even without access to their email. Decide if you can or should honor promises that the AI made for you. Go out of business and never realize that your emails had a 15% deliverability rate. Have customers leave in disgust because "the lights on are on and nobody is home" at your company.

Yeah, HTML mail is a hassle, even if you know how to code. (Maybe even more because it is so freakin' demented...) But what really bugs me about marketing email is all the other liability that is involved, particularly when it comes to deliverability. 45 min to craft an important marketing email is worth it, I've seen serious consequences of getting one wrong and what I really want is something that lets me put in my 45 min and know I am really done with it and there won't be quality problems, not 40 seconds now and know that if I do it 10 times it might give away the store on my behalf.

I rewrote a simple RAG ingestion pipeline from Python to Go.

It reads from a database. Generates embeddings. Writes it to a vector database.

- ~10X faster - ~10X lower memory usage

The only problem is that you have to spend a lot of time figuring out how to do it.

All instructions on the Internet and even on the vector database documentation are in Python.

I dread the day I see an ad from an LLM, but I am unsure how this is different than Google being an intermediary between myself and reaching the rest of the internet. Specifically, this statement...

``` adding an untrusted middleman to your information diet and all of your personal communications will eventually become a disaster that will be obvious in hindsight ```

...seems like it could be said for Google right now.

No, FSD suffers the same problem, because it has the same insufficient sensor stack. I already debunked that here: https://news.ycombinator.com/item?id=43614273

Things are not changing rapidly, this has been a failure mode on Teslas for almost a decade; it's been a problem at least since 2016 when Joshua Brown was decapitated by his Tesla running on AP. People keep saying "no, that was the last version. The new software/hardware version fixes it", but the looney tunes test demonstrates Tesla's sensor stack continues to be fundamentally insufficient.

And this is why: https://insideevs.com/news/658439/elon-musk-overruled-tesla-...

Musk thinks he knows better than his engineers how to solve this. And no, I don't consider Musk to be an engineer, he's a showman.

This. MCP/tool usage in agentic mode is insanely powerful. Let the agent ingest a Gitlab issue, tell it how it can run commands, tests etc. in the local environment and half of the time it can just iterate towards a solution all by itself (but watching and intervening when it starts going the wrong way is still advisable).

Recently I converted all the (Google Docs) documentation of a project to markdown files and added those to the workspace. It now indexes it with RAG and can easily find relevant bits of documentation, especially in agent mode.

It really stresses the importance of getting your documentation and processes in order as well as making sure the tasks at hand are well-specified. It soon might be the main thing that requires human input or action.

Grandparents from both sides had a small patch of garden, and it was used to the fullest, produce was eaten for rest of the year. Yes a significant portion were potatoes, which are much healthier side dish than ie rice. Mostly boiled or oven baked ones. Rest were veggies, cabbage, onions, some greenhouse stuff. And some fruit trees, but veggies mostly.

One side they lived till higher 80s, another both till 95. Active till very late, basically maybe 1-2 years before death.

The thing is, they all lived frugally (and under hardships of communist rule, thats why garden). No junkfood as we know today. Tons of slow physical work on that garden. No vices like frequent alcohol consimption or cigarettes.

One of their sons (aka my uncle) smoked half a pack a day. Dead at 54 from heart attack, had a cancer before but got cca cured. Another daughter got over time overweight, little physical activity, and as I learned only recently became over time an alcoholic. Dead from an heart attack at 62.

Some folks I know have much worse lifestyles (ie smoke more than uncle, plus are more overweight, plus are alcoholics) yet keep living much longer.

Not sure what I want to say with all this, maybe that eating veggies is not enough. Its whats the rest of the plate and how much of it, how active you are, how stressed, how much exposure to bad chemicals. And genes, one thing completely out of control, but as mentioned above they alone wont save you.

The problem with mRNA vaccines is that we did not downplay and censor charlatans enough. We allowed anti-vax rhetoric to spread like wildfire on Twitter, Facebook, and the like. Our scientists and doctors actually humored these people, and that was a huge mistake.

As soon as you tell an anti-vaxxer something like "there are risks, but..." all they hear is "aha!! I knew it was poison!".

Nobody on planet Earth said that the vaccine was 100% safe, nor that it was 100% effective. Because no vaccine, and no medicine, is. But we allowed people to revel in their own fear and anti-establishment mentality, and because of that, a lot of people died that did not need to.

Picking up on your acre of potatoes: no, you don't need oxen for this. In fact one reason for the importance of potatoes historically is that you can grow them on marginal land with only hand labour. There are various techniques such as the lazybeds used by displaced Highlanders in Scotland, but they don't need oxen. In fact oxen had their heyday before the iron ploughshare, as you needed a team to pull the older wooden plough, and the plough was used for planting grain. Of course these days it is also used for planting potatoes on rich land, but that's not essential.

This is exactly what the article is arguing people are doing when betting on the Jesus thing:

> [Time Value of Money] The Yes people are betting that, later this year, their counterparties (the No betters) will want cash (to bet on other markets), and so will sell out of their No positions at a higher price.

...

> Has this galaxy-brained trade ever gone well? Yes! In late October of last year — a week before the election — Kamala Harris was trading around 0.3% in safe red states like Kentucky, while Donald Trump was trading around 0.3% in safe blue states like Massachusetts. On election day, these prices skyrocketed to about 1.5%, because “No” bettors desperately needed cash to place other bets on the election. Traders who bought “Yes” for 0.3% in late October and sold at 1.5% on election day made a 5x profit!

Different people prefer different formats for information. Some people prefer to read the manual from start to finish while others learn better seeing the same concepts in a hands-on tutorial.

From reading the sample of OP's book, it seems far more practical and accessible than the bash manual, so I'm not surprised that a lot of people would read OP's book that have no interest in reading the bash manual cover to cover.

On the lipid nanoparticle toxicity, I remember an article from either 2020 or 2021 that claimed they had some sort of breakthrough in 2019 that reduced the toxicity, though didn't solve it completely.

Might go against the grain here but I actually quite like the website, as minimal as the new one is. I don't want to oversell it, since it's not really super "out there", but the author put some nice humanist touches there like the hand drawn mouse that lights up when you hover over a link.

Could use some color, but it serves its purpose and I don't find it sacrifices readability as much as some others in this thread are claiming.

If there's two beds, maybe. If one bed, doesn't matter how many people sleep in it. Maybe twice the towels?

I'll say over the years most places do not respect the "if the towel is not on the floor don't replace it". I'm fine with reusing a towel to dry off twice, but some hotels change them every day, even when their signage is indicating a protocol to prevent that sort of waste.

> Unlike shopping at retail stores or Costco, bulk discounts are unusual for airlines – at least not just for booking just two passengers instead of one. And these higher fares for one passenger are the opposite of what we typically see, where travelers booking for two passengers or more wind up getting charged more per person than a single passenger.

This isn't strictly true. Airlines have long offered bulk pricing through travel agencies and booking partners.

There are a couple travel agencies in Ushuaia that sell open cabins at steep discount for cruises heading across the Drake Passage. If you've got a little flexibility in your schedule, you can set foot in Antarctica for a lot less than if you bought a ticket anywhere else.

also: be sure to make offerings to the sea gods before sailing because crossing the Drake Passage can be... exciting.

No, not really. What I was doing was playing predictable spikes in volatility in the market over a long span - theoretically i could have done it forever had the market never closed. I also doubt the hillary market moved because of liquidation needs in other markets - it was driven almost entirely by conspiracy theory news. I followed it very closely, it was not this at all.

US manufacturing per capita dominates China, when measured in dollars. It's laughable to even bother comparing their industrial output. In other words, being an advanced economy, the US manufactures more complex, i.e. expensive, goods. The US doesn't waste time making low-cost items. There's no money to be made. Even China is getting out of that game.

The US only has so many people and resources. Do you want to spend those resources making stuff destined for Dollar General? No.

> Traveling solo is already brutal because hotels and Airbnbs are priced on the assumption of two travelers

The cost for the hotel and Airbnb doesn't really change a lot, if there is more than one person staying in the room. More or less another set of towels and a bit more soap. Even providing rooms with single beds only brings down the costs marginally.

Could it be because anti-vaxxers are generally anti-medicine and are therefore not getting tested when they probably should?

Obviously, if you don't believe in Covid, you're going to have way less Covid. Because you don't even believe it exists - so when would you ever admit to having it?

It could also be that the people who get boosters happen to be the most likely to contract Covid, and that's why they're getting the booster. Like if they're immune-compromised, or work at an Airport or something.

I'm skeptical of any hardware play here - As Marques Brownlee has said a lot when trying new ai hardware, "Smartphones are kinda OP."

Phones have gotten really good through incremental improvement and keeping some backwards compatibility so they were always useful at every point in their evolution. It's hard to imagine another device for ai that isn't just better served as an app.

> Side note, I'm surprised that these types of scientific surplus stores have lasted longer in the upper Midwest than places like silicon valley or near bell labs in NJ.

Real estate prices are a big factor. Rents in silicon valley, and I suspect NJ have increased much more than midwest rents. Even if the store location is owned, when the business owners are looking to retire, it's then a question of selling the business with the space or closing the business and selling the space by itself, and the value of the space is probably enough that it doesn't make sense to tie it to a business.

Add a bit of reality that manufacturing and the surplus it generates has mostly left silicon valley and NJ, and it makes more sense to have such a business elsewhere.

They don't claim that. They say LLMs only generate text someone has written. Another way you could refute their premise was by showing the existence of AI-created programs for which someone isn't a valid description of the writer (e.g., from evolutionary algorithms) then training a network on that data such that it can output it. It is just as trivial a way to prove that the premise is false.

Your claim here is slightly different.

You're claiming that if a token isn't supported, it can't be output [1]. But we can easily disprove this by adding minimal support for all tokens, making C appear in theory. Such support addition shows up all the time in AI literature [2].

[1]: https://en.wikipedia.org/wiki/Support_(mathematics)

[2]: In some regimes, like game theoretic learning, support is baked into the solving algorithms explicitly during the learning stage. In others, like reinforcement learning, its accomplished by making the policy a function of two objectives, one an exploration objective, another an exploitation objective. That existing cross pollination already occurs between LLMs in the pre-trained unsupervised regime and LLMs in the post-training fine-tuning via forms of reinforcement learning regime should cause someone to hesitate to claim that such support addition is unreasonable if they are versed in ML literature.

Edit:

Got downvoted, so I figure maybe people don't understand. Here is the simple counterexample. Consider an evaluator that gives rewards: F("AAC") = 1, all other inputs = 0. Consider a tokenization that defines "A", "B", "C" as tokens, but a training dataset from which the letter C is excluded but the item "AAA" is present.

After training "AAA" exists in the output space of the language model, but "AAC" does not. Without support, without exploration, if you train the language model against the reinforcement learning reward model of F, you might get no ability to output "C", but with support, the sequence "AAC" can be generated and give a reward. Now actually do this. You get a new language model. Since "AAC" was rewarded, it is now a thing within the space of the LLM outputs. Yet it doesn't appear in the training dataset and there are many reward models F for which no person will ever have had to output the string "AAC" in order for the reward model to give a reward for it.

It follows that "C" can appear even though "C" does not appear in the training data.

>Not only are they allowed to bill you whatever they want, they are never under any actual obligation to put you on the plane.

With exceptions, once you have paid for a ticket all commercial passenger airlines are obligated to transport you under their contract of carriage.

All airlines must do this, I even looked up the contract of carriage for the shittiest airline I could think of and Frontier has this to say:

>Involuntary -- If insufficient passengers volunteer, passengers who cannot be accommodated on the flight will be denied boarding and Frontier will provide transportation on a Frontier flight to the same destination. After a passenger’s boarding pass is collected or scanned and accepted by the gate agent, and the passenger has boarded, a passenger may be removed from a flight only for safety or security reasons or in accordance with Section 3 of this Contract of Carriage.

They must also compensate you. If being denied boarding delays you for 1-2 hours you get 2x the cost of the fare up to $1550 and 2+ hours 4x up to $2150.

And they still have to put you on a plane:

>A passenger denied boarding, voluntarily or involuntarily, pursuant to this section, will be transported on Frontier’s next available flight on which space is available and at no additional charge.

https://www.flyfrontier.com/legal/contract-of-carriage

Contracts of carriage are pretty much boilerplate but all of this is to say: if you pay, show up on time, and aren't denied boarding for a safety reason airlines are obligated to transport you to your destination.

(in the US)
