arrowleaf··on Montana becomes first state to enshrine 'right to compute' into law
Abundance of natural beauty and recreation opportunities
arrowleaf··on Harnessing America's heat pump moment
The physics of heat pumps disagrees with you. The freezing point of water has no bearing on at what point they become less effective.
arrowleaf··on AI overviews cause massive drop in search clicks
For the past ten years I've run a side project that estimates the word count of books and how long it takes to read them. Maintaining and improving this requires tens of hours a month, and a few hundred dollars in RDS, ECS, etc. costs. Two years ago I was at least breaking even on affiliate income, so the cost put into it was purely my own time and effort which I enjoy. These days my total traffic numbers are about 10x, but human traffic is down 50-70%.

I'm basically paying to host content for AI crawlers to scrape and I don't know how much longer I can do this. I'm adding Goodreads-esque features currently, but if it doesn't get the sign ups I'll be forced to archive the code and take the site down.

arrowleaf··on Neanderthals operated prehistoric “fat factory” on German lakeshore
Frame or shape leather hide to hold water, add water and hold over flame or add hot rocks.
arrowleaf··on How I program with agents
Are you using the same tools as everyone else here? You absolutely can ask "why" and it does a better job of explaining with the appropriate context than most developers I know. If you realize it's using a design pattern that doesn't fit, add it to your rules file.
arrowleaf··on OpenAI reaches agreement to buy Windsurf for $3B
Companies don't do these acquisitions with cash on hand. It's OpenAI and the whole pool of their creditors and investors.
arrowleaf··on Gooey rubber that's slowly ruining old hard drives
Lighter fluid can make plastics brittle. Odorless mineral spirits, shop towels, and gloves would be my next step.
arrowleaf··on OpenAI O3-Mini
Or further the hype and name it o9.
arrowleaf··on Hacking Subaru: Tracking and Controlling Cars via the Starlink Admin Panel
Assuming `samwcurry@gmail.com` belongs to the same person who owns samcurry.net, they changed their own password.
arrowleaf··on FTC bans hidden junk fees in hotel, event ticket prices
Great! My wife was reading me ticket prices for an event on Ticketmaster yesterday, I kept telling her she needs to add them to the cart and start checkout to know the real price. She did just that and to my surprise the price didn't change at all!
arrowleaf··on Cooking with black plastic is particularly crucial to avoid
I don't have SS cookware, but cast iron is basically non-stick. A teaspoon of oil isn't going to break the bank.
arrowleaf··on Cooking with black plastic is particularly crucial to avoid
Food-safe wood conditioner (or just beeswax, or coconut oil, etc.) is basically free, and you should be taking care of everything wooden in the kitchen on a semi-regular basis. If your wooden cookware is degrading, I'd be more worried about the state of your wooden cutting boards.
arrowleaf··on Cooking with black plastic is particularly crucial to avoid
If your cooking utensils are gouging or pulling up 'seasoning', it's not 'seasoning'. Seasoning is a micrometer-thin layer of polymerized oil. What you're describing is carbon build-up from a poorly cleaned pan.

At least once a week I give my vintage cast iron a good scrub with Dawn powerwash and chainmail, dry on the stovetop, apply a layer of Crisco, and then wipe it all off as if I put it on by mistake.

arrowleaf··on Study: DNA corroborates “Well-man” tale from Norse saga
Tangential, but anyone interested in literature should read "The Sagas of the Icelanders" if they have not already. The early Norse and Icelandic sagas are a treasure trove of great stories. I think about them nearly every day and it's fun to recognize similar plot points in modern novels.
arrowleaf··on Show HN: A website for comparing protein powder prices
Seriously, why is it so hard to find a protein powder that doesn't include Stevia (or its distilled, chemical name). I don't care about my protein powder being sweet, but if it's gonna be sweet, give me some raw sugar. Stevia is bitter and ruins the whole shake.
arrowleaf··on Homemade AI Drone Software Finds People When Search and Rescue Teams Can't
Peak bagging is a very common term in the outdoor sports world. This complaint is like a non-tech person reading a Wired article that mentions JSON and complaining that there's no explainer.
arrowleaf··on iPhone 16 Pro and iPhone 16 Pro Max
I would absolutely love this!
arrowleaf··on NASA investigation finds Boeing hindering Americans' return to moon
It's not fair competition, healthcare is full of players competing with each other in a highly regulated marketplace. The system has been set up in a way (generally with good intentions, you want doctors to have expensive malpractice insurance for example) that no matter who is providing the services, the costs to the end user are going to be high.
arrowleaf··on All of Earth's water in a single sphere (2019)
You'd have to use the volume of earth, not the mass. Google tells me that lava is ~3x denser than water.
arrowleaf··on Row Embedded Cache: Experimenting with a new pattern of caching
You can similarly use materialized views for this type of denormalization. When an update to the source tables occur you can trigger a view refresh.
arrowleaf··on Ask HN: What is the best software to visualize a graph with a billion nodes?
Truly, 100B nodes needs some sort of aggregation to have a chance at being useful. On a side project I've worked with normalizing >300GB semi-structured datasets that I could load up into dataframe libraries, I can't imagine working with a _graph_ of that size. I thought I was a genius when I figured out I could rent cloud computing resources with nearly a terabyte of RAM for less than federal minimum wage. At scale you quickly realize that your approach to data analysis is really bound by CPU, not RAM. This is where you'd need to brush off your data structures and algorithms books. OP better be good at graph algorithms.
arrowleaf··on Intuit to Cut, Then Hire, 1,800 Workers in Pivot Toward AI
I'd be real curious to see their ROI calculations on this strategic move. Laying off those 1800 employees will cost them $260 million, before factoring in hiring costs for 1800 highly technical replacements.

Salaries for experienced SWEs in Boise are cheap. Looking at levels.fyi there's a recent salary from an Android engineer with 5 years of experience grossing 143k. If they're looking for FAANG talent they won't even be able to poach a college grad for that amount.

arrowleaf··on Intuit to Cut, Then Hire, 1,800 Workers in Pivot Toward AI
In the Boise market, Intuit is laying off 157 employees and announced the closure of their campus due to Boise not being a strategic location for AI R&D. This comes after Intuit bought the Boise-local time-tracking software company, TSheets, and expanded the TSheets campus with a second building to accommodate up to 900 employees.

arrowleaf··on L(O*62).ONG: Make your URL longer
If it looked for `://` then stuff like `mailto:me@fake.email` would break.
arrowleaf··on The Birth of Parquet
Using polars in Python I've gotten similar to work, using LazyFrame and collect in streaming mode:

``` df = pl.scan_parquet('tmp/'+DUMP_NAME+'_cleaned.parquet')

with open('tmp/'+DUMP_NAME+'_cleaned.jsonl', mode='w', newline='\n', encoding='utf8') as f: for row in df.collect(streaming=True).iter_rows(named=True): row = {k: v for k, v in row.items() if (v is not None and v != [] and v != '')} f.write(json.dumps(row, default=str) + '\n') ```

arrowleaf··on 3rd Edition of Programming: Principles and Practice Using C++ by Stroustrup
It would have been awesome if that ISBN issue were an actual ISBN re-use issue. I've run into issues coupling my system's design to the assumption that ISBNs uniquely identify a single edition of a single book. The intent of ISBNs are to be unique, but mistakes are made and resellers lose track or straight up abuse some ISBNs.

What do you mean by TFA?
arrowleaf··on Court approves 3M multi-billion dollar settlement over PFAS in drinking water
This HN comment section is fascinating from a sociological point of view, most of the debate here comes down to whether an individual believes the burden of proof lies in proving safety vs proving danger when releasing a product with unknown risks and externalities.
arrowleaf··on Research shows plant-based polymers can disappear within seven months
This is a good chance to ask something I've wondered for a while, why isn't cellophane more commonly used as an alternative to plastic film? Is it coatings on cellophane that make it just as bad as plastic? Or does the environmental impact of producing cellophane outweigh the fact that it's biodegradable?
arrowleaf··on Show HN: Wallstreetlocal – View investments from America's biggest companies
There are a lot of GIS / mapping software that shows property ownership and their boundaries, useful for hunting. onX, for example, and I think you can purchase 'ownership layers' on stuff like Avenza.

I agree with what you're saying though, it would be cool to take something like those property owner layers and find the ultimate legal entity for stuff like LLCs owning land.

E, only semi-related: In the 'urban design' part of the internet I've seen really cool mapping that puts bar charts on top of a city's grid, with the bar charts being how much tax revenue the city generates. It's really stark to see skyscraper-sized bars in downtown cores and mostly flat all around where cities have zoned residential separate from commercial, or even where suburbs tax less than the core city.
