samtho··on Homes need to be built for better internet
> many new homes use metal "structured cabling" boxes (which block wifi signal)

Which are not meant to house a wifi access point, these are fine for (wired) network routers and the modem, but if you have this setup, your wireless access point should really be on the ceiling.

samtho··on Homes need to be built for better internet
I mean, do you expect them to alter the laws of physics to your preferred taste? Most overhead installs must attach to the closest point on your home to the pole.
samtho··on Dieselgate, but for trains – some heavyweight hardware hacking
Yes, but “Dieselgate” is not appropriate here because that term has “cheating” loaded onto it, which represents a different struggle for companies than vendor lock-in. What this company is doing is related to DRM and arguably closer to what John Deere does with its products.
samtho··on Modern automotive electronics will lead to a mechanical revolution [video]
It’s easier to fix with off-the-shelf parts (blown capacitor, damaged MOSFET, etc) than a part in which is manufactured for and by the automaker (e.g. variable valve timing component).
samtho··on The EPA wants total removal of lead pipes
As pointed out in a different comment thread here, that’s a header tank which was used in older, multi-level buildings where city water pressure was not adequate for the rise to upper floors. Builders would set up a tank that slowly filled using the lower pressure and could act as a sort of mini water tower for the building. This did not contain hot water, but there is a chance a hot water tank was using this supply.
samtho··on Airbnb's Silent Killer
It always struck me as strange that AirBnB never went in the direction of providing a simple base station with a CO/CO2 detector, noise sensor, Wifi AP (for IoT locks, lights, etc). I know the whole “hardware is hard” thing but you can surely find a vendor already selling something like this that’s most of the way there and can be white labeled.

I suppose on the flip side, rental gig economics is often predicated on the fact that corporate provides as little as legally or even ethically possible.

samtho··on Who makes the most reliable new cars?
Having a newer VW with VCDS is a superpower. If you are getting vague codes (e.g. Air Intake Leak), you get really good at analyzing sensor data to determine exactly what an issue might be and can either fix it or swap the sensor, most of which can be had for reasonably cheap (notable exceptions include MAF and emissions related sensors).
samtho··on Autonomous excavator constructs a six-metre-high dry-stone wall
The problem with dry stone construction is that you cannot determine the performance characteristics required for, say, a building foundation. Not all boulders are created equal, but a professional concrete pour, mixed and installed to the manufacturer’s specification is going to have a guaranteed maximum strength- something random boulders will not have.

What we can do is create our own concrete mix using Portland cement (the “glue”) and locally sourced materials to bulk it up such as gravel, aggregates, sand, etc.

samtho··on Almost half of Californians speak a non-English language at home
Europe and United States have nearly equal land area of just shy of 4 million square miles. There are 24 official languages of the European Union and English as the lone, defacto language of the USA.

Why would anything else be expected from the American education system when, for example, you can travel the entirety of the US and most of Canada and not have to worry about finding someone who speaks English. The education system in the US is trash for a few reasons, but only teaching English to all is not one of them, and I say this as someone who lives in the US and speaks a few languages.

samtho··on ChatGPT generates fake data set to support scientific hypothesis
A null result, or the absence of evidence, is not evidence of absence. If you fake a null result, you’re not asserting anything other than you could not measure and collect supporting data using your experiment to prove or disprove a hypothesis. It is difficult for someone doing replication to accuse you of ill-intent, as opposed to faked data that proves your point when anyone else can replicate your experiment and get totally different or even contradictory results.
samtho··on YouTube blames ad blockers for slow load times, not the browser
Every since LLMs made it into the mainstream via ChatGPT, it’s really become a matter of time before most of the new content being produced is just generated, SEO nonsense - which we can see the beginnings of right now. Big media companies used to pay interns to write barely legible articles and use word spinners to sub synonyms but now you can create, on the fly, useful-sounding content that neatly accompanies the current article. Advertisers can also use crude prompt queries like “write a maximum N word hook targeting X audience, relating to Y, advertising Z product” and dynamically create A/B (A/B/…/N?) tests and see what performs 0.2% better.
samtho··on OpenAI staff threaten to quit unless board resigns
This feels like a sneaky way for Microsoft to absorb the for-profit subsidiary and kneecap (or destroy) the nonprofit without any money changing hands or involvement from those pesky regulators.
samtho··on Ask HN: How many people on Hacker News live in rural areas?
The problem with rural areas and cars is not usually getting from unincorporated settlement to the big city, it’s getting from your home in an unincorporated settlement to the Main Street of the closest city with a Walmart. Especially as you look eastward into the US, there is a spider web of tiny junction cites, settlements, town, etc, all would be difficult to serve with mass transit effectively.
samtho··on Ask HN: How many people on Hacker News live in rural areas?
I’ve been primarily a city dweller for most of my life but have had a few stints in very rural, mountainous areas and I cannot get enough of it. Think gold country in Northern California between Sacramento and Lake Tahoe.

There are a few advantages to settling here:

- Quiet: As long as you’re off the main road by a mile or so.

- Cheap: Land sales are usually FSBO and you have to be in the know. Locals generally don’t like selling their land to where it ends up on Zillow.

- Utilities: Most land is federal or state owned but the few private lots often have power and telecom on one end of the property.

- Building permits: Easy to get in unincorporated county assuming you’re outside of TRPA. As long as you are not cutting down trees, you’re good (usually)

- Allergies: I find it easier to breath even very thin air (elevation is about 5000 feet)

But there are also some drawbacks, too:

First off, Snow. The mountains get loads of this goddamn frosty Satan jizz. People cannot drive with it being either too cautious or too aggressive - both are very dangerous, sometimes it blocks private roads so you’re trapped until a neighbor with the snow blower is kind enough to come clear the road (there is a startup idea here I’m sure). For the driving part, there are few feelings worse than stepping on your brakes and realizing they have frozen over despite needing them to be functional in about 3 seconds. Snow also also breaks random stuff, allows water enter orifice, turns into black ice, makes going grocery shopping dangerous, and in general is a scourge if you have to go outside for any reason.

On a similar topic, convenience. In the city, I can generally find 24/7 stores. We have a handful of Safeways, WinCo, and 7-Elevens. In the mountains, things shut down for any weather, it’s 20 miles away, and the gas station may be closed. So you have to stock up, on everything. I have 10 gallons of gasoline in two 5gal containers (that I cycle through regularly), propane (so many tanks, all either full, partially used, or empty), canned food, frozen food, indoor dried, de-pested firewood, drinkable water, sat phone, spare adjustable tire chains, the list goes on.

Lastly, the weird shit that just happens. All the odd things you see in the deep woods, on your property cameras, random people that have no business being there (lost tourists, tweakers, illusions, etc). I saw (on my cameras) a guy in full business attire walk up to my remote cabin, look around then look directly at the camera, and casually walk the away. I’ve seen on a hike a newish Kia Optima stopped in the forest, driver side door open, keys in ignition, chime still ringing. From my porch, I’ve seen a girl in a white night gown walking along the ridge across the road at night. I’ve also seen strange shit like a mini cement obelisk, shrines to deerman, a wooden staircase to nowhere, half buried vehicle from the 1950s. I’ve also seen several bears, a mountain lion (well, two but one was someone’s pet and was dangerously sweet), deer like crazy (but no deerman yet). Also, it gets very dark. Darker than you can imagine sometimes.

Despite all of this, making your own power and being off grid is cool.

samtho··on I used AI to make an app to help me with my ADHD
For adults, the hyperactivity manifests more as restlessness and impulsive behavior. Conversely, tasks you find under-stimulating (boring tasks, waiting in line, driving in traffic) may feel extra draining or mentally painful.

Your living space may be cluttered or may become cluttered if you do not keep on top of it. Dishes can pile up and cleanup tasks feel insurmountable. Ironically, when you want to clean, you might hyper-focus into a mega deep clean.

You may also find that starting tasks is very difficult and you won’t until it become a crisis. Tasks with no clear “done criteria”, non-linear steps, or undefined processes will be the worst. You will either way over prepare or go in without any information and just wing it because it’s painful to get sucked into a rabbit hole. You might understand how badly this can (and will) turn out, but can’t seem to do anything about it.

You’ve also likely had many jobs, have an emotional hair trigger, tend burn bridges, cannot stand stupid in your life, but feel inadequate for, despite having good intentions, can’t seem to get anything done.

samtho··on Smart drugs reduce quality of effort, and slow decision-making
Let’s say for the sake of argument (because it’s not true) that the only possible benefit of psychedelics is “fun”. Assuming sensible doses do not cause harm, what is the problem with it only being fun?
samtho··on Rolls-royce confirms all of its current engines can run on 100 percent SAF
“Sustainable” as a marketing word was likely chosen to refer primarily to itself, i.e. the production of the fuel itself is sustainable compared to drilling for a known finite resource (crude oil). However, it is ecologically sustainable in that we are using material already making the rounds as opposed to unsequestering carbon sinks only to immediately burn.

There are other benefits, CO2 is not the only greenhouse gas around, and conventional Jet-A releases non-CO2 emissions into the atmosphere. SAF has stricter requirements as to what sort additives are allowed based on each chemicals specific burn profile.

samtho··on URL Explained – The Fundamentals
For the query portion, it really depends if your are reading it server side or client side and using the WHATWG standard[0] which itself just mirrors convention. However, the standard dictating how a URL might be formed does not mandate anything about the query string that makes it parsable.

samtho··on Wyoming discovery could be America's first new source of rare-earths since 1952
There are a bunch of steps in the refining process. One of the first step is pulverizing/grinding where you can separate out the constituent components based on density. This step can done locally and will cut the volume of the ore by 75-90 percent.

However, given the regulatory environment in the US surrounding refinement, there is likely a huge opportunity for innovation in this space.

samtho··on Omegle 2009-2023
I think the post you are replying to was trying to say this, but less precisely. It used to be that a MySpace, account profile on DeviantArt, Flickr, an online forum, or even a personal website was another human trying to connect with (or troll) someone, and that everyone was putting out content because that’s how you needed to exist.

Nowadays, I’m sure that 95% of all content I see is made by a media company for hire, mega corporation, or, most recently, word soup from an LLM where, in a strange twist of fate, I’m just a lab mouse in a giant, AI created A/B test trying to determine which option gets 0.2% more clicks. The age of casual creator is mostly over. Everything you do must be to build or enhance “your brand” and its a full time job to keep up with huge teams that automate the churn of information regurgitation, otherwise you’ll never be able to get enough of a following to qualify for perks that actual content creators make - and we’ve not even gotten to compensation yet. The gold rush of making money selling your brand online is over and it has been enshitified much like everything else novel and interesting in the world and on the internet.

samtho··on Bored Ape conference attendees wake up with eye pain, vision loss
The point, I'm assuming, would be to simply leave if those things indicate there is a lot of UV present. I certainly would not hang around regardless of adequate protection.
samtho··on Soda additive linked to thyroid toxicity may finally get banned by FDA
Part of the reason does include better blood testing and the definition of hypothyroidism changing. American Endocrine Society has adjusted the bounds of the amount of T4 present in the blood upwards throughout the years, increasing the number of people who are affected by hypothyroidism with no meaningful change to the population.
samtho··on The cottage industry of YouTube obituary pirates
I do some genealogy on the side and Find a Grave has been really helpful - but to only those who have died long ago. They really needed to make a system where the recently departed are off limits to everyone except confirmed, direct family members for the first few years proceeding the individual’s passing.
samtho··on How “blue” and “green” appeared in a language that didn’t have words for them
This is not unique to Amazonian languages, in fact, it’s observed so much in other languages that I wonder how strange “western” languages are to make this distinction.

samtho··on Cloudflare outage – 24 hours now
The no communication or support is the real killer here, imo. I can understand them having some catastrophic issues which I would be reasonably confident they could fix, it’s the uncertainty of the situation that makes me worry. Is this so easy to fix it will be back in less than an hour and they will communicate then? Are they going dark and I need to find a new provider asap?
samtho··on RegEx Crossword (2013)
If you’ve completed any human language crosswords before, this is a trick they use too in the form of ambiguous, common answers (e.g. “super quick, abbr” can be ASAP or STAT - for more annoyance, notice letter 3 is the same in both), usually requiring you to get crosses to figure out exactly what fits.
samtho··on Current thoughts on social media
Without siding with Facebook here, that was extremely suspicious behavior.
samtho··on My rude-ass car
Can confirm, have a 2012 GTI, replaced the stretched chain on it about 10 days ago. The problem is that they provided no service interval for the timing chain when it really needs replacement every 80K miles. It’s an enthusiast car so there are a ton of aftermarket parts that are of good quality and VAG cars share so many parts (the 2.0T e888 engine is in a ton of vehicles from 2008 through today). My car has 211K and I intend to take it well over 300K.
samtho··on My rude-ass car
> Also I find it odd that US cars often have the same colour indicators as brake lights.

I have lived in the US my whole life and I hate this. In a world where you have to disassemble the trunk interior to change a bulb, burned out one’s often go unfixed. It’s a constant game of, “is that a left blinker or someone who’s right brake light is out and they are just pumping their breaks?”
