Show HN: Jq Jake, an interactive approach to learning jq
jq Jake was inspired by the difficulty I was having introducing and teaching jq to coworkers, particularly when working with complex inherited filters.

jq is popular enough that for one-off situations LLM's typically can write new filters and sufficiently interpret existing filters, but for more regular work jq Jake is my attempt to help people understand the jq mental model.

Not consistent with my empirical tests. I asked Claude for references on the demographics of wild rodent populations—-not exactly a hot topic, and all four references were spot on, including two not even listed in PubMed.
Oh, I don't think so either, but if you think back to the asm.js times, there was a clear goal of "simple and higher perf", but now it's going in a direction for maximum compatibility with existing stacks (GC, WASI, etc) at "any" cost

Imperfectly acknowledging one part of a larger issue is a necessary first step.
Given that drone warfare is now a thing this seems like it could be useful as the basis of a personal drone detection and warning kit that soldiers could wear over their helmet to spot drones and give say an audible warning in the soldiers ears that lets the soldier locate the drone direction and maybe azimuth with pitch - lower frequency for a low drone and high for one more overhead. Not sure if such a thing already exists. That and a shotgun would be a reasonable defense.
That's really cool. I am always impressed about that people are able to do with Krita, this makes me happy as a KDE developer even though I am not really involved with Krita.

I live a block away from a train crossing for a track that does a lot of local refinery transfers and occasional has freight. It has the normal old style crossing with an arm on each side with lights, a loud bell, and trains required to signal with horn. There are 8 road crossings in a short distance so each train is signals 8 times nearby.

The requirements for a no-signal crossing is essentially a pedestrian gate. The quote the city has for each crossing was if I remember right 1.5 million usd. And you’d need to replace many of them. The city doesn’t want to prioritize that much money. (FWIW I agree)

The worst thing is we have under utilized tracks going all over the region and no commuter train service. Even with the rail expansion prior to the Olympics (I’m near Los Angeles), the commuter rail is only being extended to the northern most edge of the city.

Neighbors have been fighting against commuter rail every step of the way. I’ll say attending local govt and rail proposal meetings is at once interesting, impressive at what some groups are trying to achieve and disturbing at the lengths people go to prevent change.

So what it misses is that the ADM formalism is a subset of GR, in that it can only simulate a subset of the full equations for GR. It also gives a lot of reasoning there that is quite faulty with respect to answer the question of if its strictly equivalent

>Wait, does this decomposition change the physics? Or is it just a different mathematical approach? I think it's the latter

This for example is faulty reasoning, because its not an either or situation

>I should check if there are any subtleties, like constraints or boundary conditions that might affect equivalence

This is also faulty reasoning, because it assumes that non equivalence must mean that they produce difference physics

>Another point is the initial value problem. ADM is used for that, which suggests it's a way to set up initial data consistent with GR. If the equivalence wasn't strict, then initial data in ADM wouldn't correspond properly to GR solutions. But I think they do, as long as the constraints are met.

Notice how its trying to sneak a fast one past you. Its saying that because ADM with valid initial conditions maps to GR, therefore GR maps to ADM - which is a logical fallacy! It makes this mistake several times in its chain of reasoning

The issue is its not doing any real reasoning, and isn't capable of actually making deductions. Its about as productive as just.. throwing all the pieces of information on the floor, and picking them up in a random order

This isn't really getting into the weeds with astrophysics, its ADM 101, and deepseek is just.. lying right to your face with confidence, presented under the guise of a chain of reasoning

I'm obviously approaching this from an extremely biased perspective, but in the wake of seeing so many people around me helplessly complaining about recent negative changes in government, it's very comforting to see some people getting organized and trying to do something to help. In general, I hope that more people are spurred into action than ever to actually make a change in the world rather than just reposting conspiracy theories and prophecies of doom on social media, crying that no one is doing anything.

> all creators, new and old, will use YouTube by default

I think plenty of established YouTubers would like to switch to a platform that gives them more control (even if they pay hosting) if it didn't incur a hit to their viewership. New YouTubers use it because it's free and has a network effect. Old YouTubers use it because they're locked in.
That was not an option for me at the time, but I'm glad it works for you.
Trump should kill this. It is really a "cargo cult" project: "Stargate" indeed! Why, the very idea!8-))

Building unjustified giant data centers will soak up government and private monies and resources in construction that could be better used for other purposes, will divert our attentions and then will obsolesce in 10 years or less.

While we know how to write code for LLMs, we don't understand LLM technology: when it works and when it doesn't. (We don't understand human intelligence either, of course, which doesn't help.)

Rather than "getting ahead of ourselves" and building trillion-dollar "bricks in the desert" We should first invest much smaller monies exploring the theory of LLMs and such questions as whether LLMs are derivative of human intelligence and whether there are better alternatives.
This. One of the main challenges in GenAI today is UX: how do you actually embed the "intelligence" of LLMs into software in innovative ways that are not mere chatboxes, because prose sucks for showing information and using said outputs for making decisions.

Even if you make the LLM write prose in beautifully formatted markdown, you're still transfering mental complexity to the user in the way of parsing text responses.
There are and is currently more residential towers being built in SF. https://youtu.be/kP08AWGfG-w?si=ax8R4l8z0Hd4t_HJ

It is zoning that is stopping high density from going up. The house owners are stopping it. You. When you remove those restrictions you get tons of projects wanting to execute on that.

Look up builders remedy.

In the Bay Area, examples of "Builder's Remedy" projects include proposed developments in cities like Mountain View, Menlo Park, Saratoga, and Los Gatos, where developers leverage the state law to build high-density housing projects in areas previously resistant to new development, often by proposing large apartment complexes or mixed-use developments on sites zoned for lower density housing, particularly in affluent communities that haven't met state housing mandates; notable examples include a 200-unit project at 1920 Gamel Way in Mountain View and a large development at the Mountain Winery near Saratoga, which could include a hotel alongside residential units, all while utilizing the "Builder's Remedy" to bypass local zoning restrictions due to the inclusion of a significant portion of affordable housing within the project.
Key points about Bay Area Builder's

Targeted areas:

Developers often target affluent cities like Menlo Park, Los Gatos, and parts of Santa Clara County, where housing needs are high but local resistance to new development is strong.

High-density development:

These projects often propose significantly denser housing than what is typically allowed under local zoning, including multi-story apartment buildings.
Affordable housing inclusion:
To qualify for "Builder's Remedy," developers must include a substantial percentage of affordable housing units within the project.

Local opposition:

While intended to address housing shortages, these projects often face significant local opposition from residents concerned about increased density and potential impacts on their neighborhoods. These are rich house owners who own a home and they are the 15% who oppose the 85 percent who don’t. It’s class warfare.

Show HN: Uq – simple barebones CLI url parser
Was doing some work with urls and grew tired and frustrated trying to parse out the query params and translate url encoding to ascii. I know there are crazy regex filters for jq/fq and libraries like URI.js that I could wrap in functions/aliases but I just wanted a simple CLI binary that takes a url and spits out readable, colorized, json.

I did a few searches before I wrote it and didn't find anything but was also kind of shocked because I figured someone else must have written something like this. Anyways, here you go. Hope it helps at least one more person out.
At full speed sure, but if they use the metal chassis as a heatsink and downclock it a bit it ought to be fine, right? There are rk3588 SBCs sold without any heatsink at all (and I'm sure that does result in throttling, but presumably it's manageable)

> That's still an architectural thing. If CPU isn't an issue, why would you be running your application server on a different machine from your database?

Because that'll be too much of a scalability limitation. Rails etc are rather CPU heavy. In cloud environments it's also typically much more feasible to scale the stateless parts up and down than the database.

> Even if you have it on another machine, it's on the same switch, right (also an architectural choice)?

Yep, was on the same switch in my example.

> So latency should be sub millisecond, and irrelevant for a single request.

In my testcase it was well below a millisecond (2.8k QPS on a single non-pipelined connection would not be possible, it implies a RTT <= 0.35ms), but I don't at all agree that that makes it irrelevant for a single request.

I don't think honorable conduct has much to do with success.

Many approaches work. Ireland, Israel, India, etc. all succeeded. I think one can do things in a very dirty way, and sometimes in a very clean way. It depends on the opponents and what they're doing, and the attitudes of the other relevant entities.

US manuals usually discuss this kind of thing as an early stage of destabilization, before things go to open warfare, and I think that's correct. I wouldn't say that it for sure is an effective way to creating something suitable for the kind of disorder where a revolution is possible, but I don't think that was Mangione's goal either.

I think this was personal-- that felt he that the company had wronged him or a group of which he was part in a way that he could not get righted by the courts, so that he had to obtain revenge on his own, but maybe I'm imagining him as having my own moral view of courts and the legal system-- basically, if they will not hear a matter where someone is exploiting me, they make themselves irrelevant and I can do what I like (i.e. imagine that you get shot, and the courts will prosecute people who shoot people, so you go them-- no need for personal vengeance, but if it was done by a diplomat, you beat him to death right there, because the courts wouldn't hear you-- i.e. by being willing to hear cases, take into account any kind of thing which affects you, the courts substitute for private vengeance, and I see this is their basic function, on which they've then built).

> It's not a catastrophic disaster yet -- nearly all Americans sat at home in comfort watching the LA fires. People don't see a disaster if it doesn't affect them, then it's just a tragedy.

Yeah watch from the comfort of your own home. Give it some more time and one day people will be watching you from the comfort of their own home.

By the way I have also found that most hotels suck at draining water from the shower. Usually after only 5mins the bathroom is a complete mess. I suspect this is on purpose, so that guests don't use too much water.
This is the way. Especially if other people live in your house.

Look at this stuff as "progressive enhancement". Make the simple things work, then build on top of that. Don't replace the simple things with complicated, elaborate things. You don't want to live without lights for a week because a SD card died in a Raspberry Pi somewhere or something.

The overly complicated setup I'm using to run my smart home automation stuff shit the bed and I was too busy with work to really spend the time fixing it so... I just didn't. For six months. The only major complaint I heard was that the outside lighting was no longer turning itself on and off with the sun.

Even in the worst case scenario, all of the lights still have switches that can be turned on and off as long as there's power. It's all zwave, and I've made use of the scenes / direct associations / etc such that most of the stuff people actually care about happens without being mediated by Home Assistant. Or requiring any sort of network. When I move out of this house, I could leave it all behind and it would keep working as-is without my server, access point, active internet connection, or anything else. If there's power, it works.

All my living room lights (three dimmers) are controlled by a single dimmer.

The three way switches in our bedroom are now dimmers. One controls the lights, the other acts as a remote control for it.

The pantry light turns itself off after 20 minutes because people always forget it on.

Both the kitchen light switches turn on and off with the single, easily accessible switch.

The switch for the porch lights also turns the string lights on the gazebo a hundred feet from the house on and off.

My kid's too small to reach the regular switches, so there's a battery-powered remote switch mounted on the wall at her height in her bedroom and the bathroom. Those still work and are still able to dim the lights in her room.

Etc, etc. All without anything but electricity.

I said only _major_ complaint--my kid definitely had some complaints. We have one switch that has a couple of those RGB projector bulbs hooked up to it. When you turn that on, an automation turns off all the rest of the lights and starts playing some dance music. Her party lights still turned on, but it no longer made the music start.

If you want colour control then get smart bulbs to go downstream of your smart switches. Set them to always go to "on" when power's restored, and build that _on top_ with your automation. You'll always have a working light, your automation can always turn them on even when someone's turned the switch off like a normal person would, but when everything else is working you'll _also_ get colour control.
> the one off doesn't hurt as much as the plus four helps

Doesn’t the turn end if you hit the opponents word?
In 2025, sure. Back when that calculator came out, this kind of saving was probably worth it.
There is a certain scale at which this may ring true. This also may by a a tautological statement: when your architecture is right, your tables are well designed out, your queries are optimized to the limit, and you are smart with caching. Of course, now CPU is your problem.

Self-study?
I guess I just don't understand how you want to draw the line from the need for tolerance in itself to the necessary prescription that quiescence is the only way to be if you want to get things done. Is not taking some kind of stand precisely integrating and accepting conflict?

Like is anything purely technical? I dont think so, and the most insidious politics are the ones that are left unspoken but allowed to direct the endeavor at hand. To dream of or push for something purely "technical" or "apolitical" is simply to be guilty of the same thing your quote is getting at, but from the other direction. Instead of squashing dissent, you simply poof it out existence, you make it taboo to even talk about. How does that then become tolerance? How does it operate necessarily to help us? It is in fact no less an imposition, and is no less a political operation in the communities where this kind of view operates.
I routinely see >1hr skippable ads, whenever I make the mistake of attempting to watch on my iPhone instead of my PC (Where Adblock works). They are definitely intentional ads. I don’t know why. The products vary wildly, but are all scams or scam-adjacent at the very least.

Most of my experience with them is that if I ever fall asleep watching a YouTube video, I wake up halfway through an ad about how I can “improve my life with this one simple trick” or how “Jesus can help me if I donate now”

But they have gotten much more aggressive lately. I tried to watch a 30 minute podcast on YouTube from my phone, and gave up 15 minutes in after the fourth hour-long (skippable) ad. They don’t show the duration until you interact with the screen now, so if I’m doing something else and not able to touch my phone right away I get a good few minutes in before I think “is this ad going to end?”
Watching football this fall, I've been thinking about a little box that sits on my table and mutes the TV whenever an ad comes on.

Not decoding HDMI HDCP or anything, but a webcam + AI or whatever that watches football with me and mutes ads. Similar to plane detection, maybe. Are there any projects like this?
In theory, Bluesky, Mastodon, Pixelfed etc could offer a service where you drag and drop the button onto the Bluesky/Mastodon/Pixelfed website where you are logged in and sign the reaction in your name.
