(From the article that Slashdot links to)

> Key to making that shift has been the Los Angeles Department of Water and Power, which has ordered less electricity from the Utah plant while simultaneously building a natural gas and hydrogen burning power station just across the street from Intermountain.

Does that mean that LA is building a plant in Utah?

Why not build the plant in LA? Is it more efficient to ship electricity instead of gas; or is it just more politically convenient to pollute Utah instead of LA?

Global Drought Map is a fully serverless web application that visualizes global drought indicators (SPI, SPEI etc.) from open datasets like CHIRPS and ERA5.

All computations run client-side using DuckDB compiled to WebAssembly (WASM) — querying Parquet files directly in the browser. Spatial aggregation and indexing are handled with H3 hexagons, enabling efficient global-scale visualization without a backend database or API.

Key features: • Zero backend: everything runs in the browser • Query and filter massive Parquet files with DuckDB (WASM) • Spatial joins and aggregations via H3 • Drought indicators computed from open EO and reanalysis data • Built for transparency, reproducibility, and open data access

haha this great! I have made something similar for myself but its a tool to manage shell scripts for my projects. I create a grimoire for a given project and add reagents and recipes (shell scripts) those can be mixed individually or brewed together to form a recipe. I also have a concept of spells which are more akin to utility scripts for managing/scaffolding the grimoire.

here’s the tool: https://github.com/globz/witchesbrew

and here’s a grimoire which manage everything related to my emacs config and dependencies:

It isn't useful because you need those other things anyway and so it becomes excess data that you don't need. It can still be nice to know which lane you are in, but you have to be able to work 100% without that information, or worse then the information you have is wrong. (that is they just changed the pattern of the intersection and so you no longer can use the second from the left lane to turn)

Yeah, exactly, and I've fruitlessly read too many guides on git's data model.

What was holding me back turned out to be the fact that git has too much magic (it updates branches automatically when you commit, rebasing "does stuff", conflict resolution was just arcane).

Jj exposes all that into simple, composable principles, making everything click.

What do you think that difference in homicide rates proves? It’s caused entirely by racial disparities in homicide victimization rate. The NYC homicide rate for white victims is about 9 per million: https://www.nyc.gov/assets/nypd/downloads/pdf/analysis_and_p... (7% of 343 homicides divided by 2.7 million). The homicide rate among white people in London was also about 9 per million: https://aoav.org.uk/2024/londons-2023-murders-examined-key-f... (43% of 103 homicides divided by 4.7 million).

It seems unlikely that this pattern of homicides would be explain by differences in general government policies between the U.S. and UK, such as healthcare policies.

Of course, both scientific approaches of history and myth are the work of fabulists. eg Jung, Campbell. The point is to examine the myth and then history as the source of causal illusions.

“The myth is the prototypal, fundamental, integrative mind tool … to integrate a variety of events in a temporal and causal framework.” Merlin Donald

That's folk science, what Donald is describing (he admit this in Origins of the Modern Mind).

Remember that the causal framework must be evaded to reach scientific correlations, where multiple contradictions can lead to knowledge. Myth and history were addictive hiccups that trapped humans in way simplistic explanations.

We evade this "plain English" silliness, like economics, or go bust.

> Why not build the plant in LA? Is it more efficient to ship electricity instead of gas; or is it just more politically convenient to pollute Utah instead of LA?

Great question. It is easier to rely on existing transmission at Intermountain than it is to build a gas turbine in LA (along with whatever infra is needed to provide a reliable supply of fossil gas to the generator site). You can even add batteries, solar, wind etc in the future at that site; coal sites are being remediated and turned into battery storage colo in many situations to rely on that existing transmission infra.

No, I see them using the web interface actually, just like they've done so up until now.

I don't think for instance this was keeping a lot of people from switching to Fastmail from let's say Gmail, which also doesn't offer a desktop client.

If Fastmail has an adoption problem it's still from people not wanting to pay for their email, a desktop app is not going to change that.

Thanks a lot for your kind wishes and detailed feedback! I’m a bit unsure what you mean by not having a “product” — I do have an online notepad and a Cornell notes tool; I just shared the homepage, not the specific tools (there are currently two, and I plan to expand gradually). Do you mean a large product or so?

I really appreciate your thoughts on monetization. I’ll definitely keep improving the notepad, Cornell notes, and other productivity tools to be added to the website to be as smooth and distraction-free as possible.

About making it open source or self-hostable, I might consider that later as more people suggest it instead of the current model.

> software-defined hardware component that does the same thing

No, you cannot.

A hard-drive needs to a have a physical hysteresis. An input/output device needs to transmit power, and be powered, by an electrical field. A visual device needs to emit light on electrical stimulation, and so on.

The only sense, in the end, in which a "computer" survives its devices being changed is just observer-relative. You attribute a "3" to one state and a "1" to another, and "addition" to some process. By your attribution, does that process compute "4".

But it computes everything and computes nothing. If you plug in a speaker to VGA socket, the electrical signal causes an the air to move, sound.

The only sense in which a VGA signal is a "visual" signal is that we attach an LCD to that socket, and we interpret the light from the LCD semantically.

The world is a particular way objects in space and time move, those exhaust all physical properties. Any other properties are non-physical, which is why this kind of computationalism is really dualism.

You suppose it isnt your physical mechanism and its relationship to your environment which constitutes your thinking -- rather it's your soul. A pure abstract pattern which needs no devices with no specific properties to be realised.

Whatever this pattern is, if you played it through a speaker, it would just be vibrations in the air. Sent to an LCD, whitenoise. Only realised in your specific biology is it any kind of thinking at all.

But why wouldn't they?? Most animals take care of their wounded peers, from ants to elephants, and often defend individuals from predators (not always! but often enough to be on countless documentaries).

This is an extremely natural behavior, not unique to humans or proto-humans, and not driven by interest or strategy. Compassion is innate.

Cruelty and contempt for the weak is a specifically human trait, and not only that, but a very recent one too.

The lack of can-do-attitude can be explained by regulations, imho. After you've seen the first few trivial things take ages because somebody has yet to stamp form 23b in triplicate and hand in 1k pages of environmental impact assessment, noise studies and socio-economic impact predictions, you loose the belief that you can do anything here. After you've been stonewalled by a few bureaucrats over a missing comma in their particular interpretation of subsection b12 subparagraph d footnote 11, you start going about your days looking for excuses not do to any work as well. After several people have cited "liability" and "legal risk" as arguments against babysitting their neighours cat for a day, you might start fearing that nebulous liability thing yourself.

The whole culture is poisoned by regulations imho.

Homelabbing is a hobby for most people involved in it, and like other hobbies, some people dip their toes in it while others go diving in the deep end. But would you say it’s “overkill” for a hobbyist fisher to have multiple fishing poles? Or for a hobbyist painter to try multiple sets of paintbrushes? Or a hobbyist programmer to know multiple programming languages?

There’s a lot of overlap between “I run a server to store my photos” and “I run a bunch of servers for fun”, which has resulted in annoying gatekeeping (or reverse gatekeeping) where people tell each other they are “doing it wrong”, but on Reddit at least it’s somewhat being self-organized into r/selfhosted and r/homelab, respectively.

Your comment is coming off as a bit defensive

Your article is coming off as a bit offensive ;)

I didn't write my article to attack git [...] I wrote the tutorial to help.

Except you didn't write a tutorial. You wrote an "I hate git and jj is better and if you think otherwise you're wrong" article.

Blue speech bubble with literally the text: "If you don't like Jujutsu, you're wrong". This is text. There's no "tongue in cheek" voice and body language here, even if potentially you meant it that way. But given how the article itself starts, I don't think there was any of that to transport :shrug:

Needless to say, I just don’t get git

Actually, it does bear saying. And I do think that if you say "everyone that doesn't think jj is better is wrong" you have to explain what you really don't like or get. No it's not needless, because not everyone has your experience. I really do not understand your pain points unless you explain them, because I've never felt them. Either because I did understand the part you didn't, because I don't need to understand that part to use it well (cutting the decision/knowledge tree in your head is a skill by itself I've found over the years - sometimes you do have to accept magic! E.g. I don't need to understand exactly how any specific LLM works to use it well) or because I simply never had a need for the kinds of feature that trip you up.

The R-value performance numbers for asbestos as building insulation are wildly divergent, but most of them aren't especially competitive with modern materials.

I'm not sure how to square that with claims like:

> With phenolic resins, asbestos products are produced which will provide insulation and retain strength when subjected to 5,000°F for periods of minutes (1 to 30 minutes) . See Figure 2.1 in which a rocket motor part is subjected to a temperature of 5,000°F. Figure 2.1. Rocket motor aft (asbestos-phenolic insulator) before and after firing at 5,000°F.

> The temperature approximately 1/8 in. from the surface exposed to 5,000°F will be approximately 200°F after 1/2 to 1 min. of exposure.

> When combined with magnesium carbonate and other similar products, heat insulators can be produced which will be useful for many years in such applications as boilers operating at temperatures from 500° to 1,200°F or 1,800°F.

We seem to use a matted "Ceramic Fiber" roll for its high-heat insulation capabilities these days, up to about 2300F-2600F depending on type. Asbestos fiber insulation seems to be good to somewhere between 1500F to 2700F depending on how you use it. Ceramic fiber is carcinogenic in a similar way to asbestos, but apparently considerably safer due to the fiber length/alignment.

Because you can see a lot of the moving parts and get involved in the actual reproduction of the sound by playing with the stylus, touching the record, slowing it down, speeding it up...

Anyway, used vinyl is a lot more fun, and cheaper. Most of my collection was in the $2-4 range in the early 2000s.

> colour labels in Finder switched from highlighting the entire file

One of the reasons I continue to subscribe (sigh) to the Path Finder (Finder replacement) app, which offers whole-line highlighting (coloring) of tagged files.

(It also has a great function to batch-rename files — including with regex find and replace, and including the ability to save and load renaming algorithms.)

Not affiliated, just a very happy user (apart from the subscription licensing model, that is).

I like this article & agree with the premise, however...

> I have created a large number of small web sites, “applications”, and libraries that I consider finished.

The author then links to a JSON Notes website where it says on the first page:

> It does not (yet) work well on mobile devices.

Yet? Finished?

> Don't mention accessibilty [sic]. I really want it to be good, but I made this for me in a few hours. I'll try one day to make it better.

One day make it better? Finished?

> I also don't know how many notes you can store [...] I don't know what happens when you run out of space!

I don't think this sounds finished at all, or even useful beyond a demo of some sort.

> In the 20th century, U.S. companies put their excess profits into corporate research labs. Basic research in the U.S. was done in at Dupont, Bell Labs, IBM, AT&T, Xerox, Kodak, GE, et al. This changed in 1982, when the Securities and Exchange Commission ruled that it was legal for companies to buy their own stock (reducing the number of shares available to the public and inflating their stock price.) Very quickly Basic Science in corporate research all but disappeared. Companies focused on Applied Research to maximize shareholder value. In its place, Theory and Basic research is now done in research universities.

I'm not seeing how you get from share buybacks to a shift in priorities in corporate research. If there's a fundamental reason why it can't be done now how it was before the 80's it's not that.

By not taking the word literally you're asking me to take your own opinion of what that word means, so that you can be right. No. My answer to that request is no. You don't get to choose what words mean. Society does. Again, democracy.

You didn't have to break any laws for me to help you vote for gay marriage. We all knew it was wrong that's why it's legal. Not because you punched someone or burned a car, or whatever illegal things you did, or in your revised view, advised people to do using the wrong definition of the word "duty."

Next time just be patient. Wrong laws take time to fix. And they take longer when you derail society into thinking that people who support gay marriage are violent law breakers.

Democracy requires that citizens have a duty to obey the law. Not a duty to break it.

Gay marriage is now the law in your example. I don't want everyone opposed to that law to go ahead and break it! Right? Wouldn't it be better if they just went ahead and tried to overturn it legally so that we normal people can do normal things like not letting them?

So, no, you don't appear to me to be the most intelligent person on the block. Certainly not enough to carry the cause for us tactfully. I wouldn't follow you. Neither would the vast majority of Americans, thankfully.

And don't tell people it's their duty to do illegal things, that is also illegal, especially when it leads to violence.

Just accept that you're not smarter. Have humility. Chill out. Get a law degree if you want to help. Don't be annoying. Don't be an idiot. Don't break the law. Have some respect for society. You didn't single handedly create it. Stop acting like you did.

We all created it; and the laws that run it. And we all need to come together and discuss what laws fit for us today. And we can't do that if you go around breaking them and acting like the conversations we agree on don't matter.

Nearing half a billion dollars doesn't sound like buggy whips to me.

And the bar chart clearly extrapolates the market continuing to grow. Not shrink.

But you still think the #1 brand in a large and growing market is "positively non-existent"...?

The project that would take months got done in a weekend, per the author's own direct estimate.

I've experienced the same - contributing a very large PR to a golang project (without knowing or having worked with the language prior). I did it because I could talk through abstractions, be willing to down dead ends (1:3 ratio for every meaningful feature), and be OK with the fun of redoing. Once you are able to do this, you literally become a 10X engineer when measured by working output.

If this process of trying and discarding 2 out of every 3 approaches sounds distasteful, you will not truly discover the deeper joys of working with the SOTA LLMs.

> Firearms for home and personal defense.

Given the current political climate, the left should definitely get on board with this one ASAP.

There's lunacy on both sides for sure, but MAGA has a pretty strong hold on blatant cruelty when it comes to their issues. Also, I'd argue the Overton window has shifted pretty far right, so you have to be pretty extreme to be considered a right wing extremist these days. In fact, some of the major MAGA rallying points could actually be points of compromise to most progressives if they weren't so cruel about it (ICE, farm slavery visas, trans sports). Plus curiously the one we could all agree on but don't hear much about on the right anymore; Epstein.

> The existence of two black holes in OJ287 was first suggested in 1982. Aimo Sillanpää, then a graduate student at the University of Turku, observed that the brightness of the quasar changed regularly over a 12-year cycle.

Damn, that's about the time it takes Jupiter to orbit the sun. That feels wildly close together for objects that mass 18 billion & 150 million times that of our own sun.

These black holes (according to a calculator I found online) have radii of 53 billion km and 400 million km, so I'm guessing they must be orbiting significantly further away, and significantly faster than Jupiter (which is ~800 million km away from the sun) - which makes sense, given the monstrous 18b figure. I wonder how far apart they are, but I don't really know how to easily calculate that right now.

I don't have kids, so I can't 100% relate, but have you dug into the notifications settings on your phone? They're extremely flexible. I've set mine up so any non-chat notification gets batched into a group that shows at 5 AM and 5 PM. This lets me check on whatever happened the previous evening while I'm having breakfast, and whatever happened during the day after I get home from work. Once I've flipped through all the notifications and done whatever other time wasting things, it goes back in my pocket and largely does not disturb me for another 12 hours.

Maybe something like that could work. If you find there are notifications that are disturbing you, but they really could have waited until the evening, toss 'em in the batch bucket. Eventually you'll tune out all the low-importance stuff and get your life back. Or find some other cadence that works for you. It takes some effort to tune these systems, but I think it's worth it.

I have taken several linear algebra courses, one from my high school and two from universities. The thing is, not all courses of linear algebra will discuss rotations the way you discuss it. One reason is that sometimes a high school linear algebra course cannot assume students have learned trigonometry. I've seen teachers teach it just to solve larger linear systems of equations. Another reason is that sometimes a course will focus just on properties of vector spaces without relating them to geometry; after all who can visualize things when the course routinely deals with 10-dimensional vectors or N-dimensional ones where N isn't a constant.

Except they've been saying that for the last 2-3 years.

I have lunch with a friend every 2-3 weeks, and he self-manages his retirement, and he's retired. It was ~2.5 years ago that he said "A lot of the financial news guys I follow say there's going to be a crash in the next 3-6 months."

At every lunch we've been following up on that, and it just hasn't crashed yet.

Speculation: The biggest reason for solar farms often being unpopular with locals is that, socially, they feel like dystopian giga-scale machines. Serving some far-away, unfriendly power. Utterly disinterested in the welfare, or even lives, of the local populace.

Vs. almost any other business (farm, mine, oil drilling, warehouse, whatever) would both hire far more local people, and interact far more with the local community.
