The explanation still kinda sucks. I like this one:

The easiest way to understand the relationship between time and space is repeat the thought experiment with the void, but assume that there is no consciousness there (i.e nothing running that can sense time passing).

Now imagine the only action you can take is to fire particles (say photons) in a given direction. In a void, that action is meaningless - the particle fires and never comes back. No information exists.

Now imagine there is a mirror somewhere in space. A particle fires, and then comes back. And maybe interacts with another particle. But still, this is generally meaningless and you cant derive any measurable thing from it, but you have a piece of information - particle comes back.

Imagine there are 2 mirrors in different directions. What you do is you set up 2 identical devices. Each one fires a particle, and when the particle comes back, it triggers a certain color ball to fall down a common shared tube, and then the particle gets fired again.

So with 2 mirrors, you get a sequence in the tube that looks something like blue, blue, blue, green, blue, blue, blue, green. Now you can make a measure of distance. You take the "blue" mirror as your unit, and say green mirror is 2 away.

You have also in fact created a clock. The tube contains information on how many cycles have passed - i.e in order to say that mirror is x away, you need to have counted x blue balls before that respective ball shows up. So you can see how distance and time is intimately intertwined. To measure distance, you have to necessarily have something that measures time.

Now lets say that the "green" mirror starts moving away from you, at a slow speed (i.e your particles are much faster. You start to see 3 balls in sequence, then 4, then 5, and so on. By comparing the difference in the subsequent position of the green balls, you can measure speed.

What happens if the speed of the mirror is 99% of the particle speed? The particle takes its sweet time getting there, and sweet time coming back. Even if you fire the particle as the green mirror is close to the particle emitter, its going to result in a measurement of a very large distance.

This is the relativistic effect where the space behind something moving fast increases.

This whole experiment demonstrates that what we consider space is precisely defined by measurements, and relativistic effects alter these measurements, which alters our perception of space.

You can do similar thought experiments to understand why space in front of you seems to shrink, why time dilation becomes a thing, and so on.

Scooters are incredibly more efficient because they weight incredibly less. A small Toyota Auygo is 860kg, a non-electric smart is 645kg.

A scooter (125cc) weight from 100 to 150Kg.

Even comparing a 150kg scooter to a car as light as a smart you get 6 time increase in weight for a motor that is not 6 time less efficient.

If I had to guess the biggest problem for most roads is the height, followed by the width. Weight might still come into play for some potential routes that otherwise had enough clearance. It's not clear from that video but it's quite possible the load fits in the 14' height limit for interstates in the state of Texas. That would make this at least twice as tall.

Hi, thanks for checking out my blog. Everytime I am on HN I am feeling bad for not writing more posts. But it is time consuming and hard, and it is even harder to focus on that having a family and full-time job.

Anyway, I think WPF was really nice framework to work with. I had fine time working with WPF and Xamarin which was very similar. Unfortunately it was abandonned by MS and now all the rage is bringing everything to the web (regardless if this is bad or good; it is more convenient for everybody).

I had couple of jobs offers to work on WPF or Xamarin through out the years but declined them because of those facts. And now seems like MAUI is the way to go to write GUI on windows.

Yeah. That's another in a long line of MCP articles and blogposts that's been coming up over the past few weeks, that can be summarized as "breaking news: this knife is sharp and can cut someone if you swing it at people, it can cut you if you hold it the wrong way, and is not a toy suitable for small children".

Well, yes. A knife cuts things, it's literally its only job. It will cut whatever you swing it at, including people and things you didn't intend to - that's the nature of a general-purpose cutting tool, as opposed to e.g. safety razor or plastic scissors for small children, which are much safer, but can only cut few very specific things.

Now, I get it, young developers don't know that knives and remote access to code execution on a local system are both sharp tools and need to be kept out of reach of small children. But it's one thing to remind people that the tool needs to be handled with care; it's another to blame it on the tool design.

Prompt injection is a consequence of the nature of LLMs, you can't eliminate it without degrading capabilities of the model. No, "in-band signaling" isn't the problem - "control vs. data" separation is not a thing in nature, it's designed into systems, and what makes LLMs useful and general is that they don't have it. Much like people, by the way. Remote MCPs as a Service are a bad idea, but that's not the fault of the protocol - it's the problem of giving power to third parties you don't trust. And so on.

There is technical and process security to be added, but that's mostly around MCP, not in it.
by MadsRC | 2025-04-14 08:03:09+00:00
When this was released I thought that perhaps we could mitigate it by having the tooling only load “rules” if they were signed.

But thinking on it a bit more, from the LLMs perspective there’s no difference between the rule files and the source files. The hidden instructions might as well be in the source files… Using code signing on the rule files would be security theater.

As mentioned by another comms ter, the solution could be to find a way to separate the command and data channels. The LLM only operates on a single channel, that being input of tokens.

Seems like it. I went to church today for the IDK consecutive Sunday and it was all right.

Not the "Western civilization is declining because the kids stopped going to church" church but a church full of old hippies and young queers. It's been fun, sometimes I get takeout on the way home

I'm also tending my own website, which nobody else has write access to, so that I can link people to information I've vetted myself. Can't link it without doxxing myself sadly

OK so he suggested injecting disinfectant. Which is basically the same as bleach. If you can’t tell that from the video I’m not sure what’s going on anymore.

He also talks about putting UV lights inside the body, which is still a bit dumb, but not as dumb as injecting or ingesting disinfectant or bleach.

If you want to say he is only says it could be ‘interesting’ to inject or consume disinfectant then sure, why not - that’s still insane and dumb in equal measure.

He even tries to walk back his comments later saying he was being ‘sarcastic’ which he very clearly was not.

> sociopathic profiteering

That "sociopathic" profiteering funds the 401(k), IRAs, and pension plans of tens of millions of Americans. God forbid these companies be run for the collective benefit of all shareholders (including special ed teachers, utility workers, and airline mechanics) and not just the lottery winners who scored the high-paying jobs at these companies.

> mass layoffs

The "Day in the Life" videos that made the rounds on TikTok sapped the general public of whatever sympathy they may have otherwise had for the FANMAGers getting sacked from their $100-300k jobs.

I've just watched video[0] from Engineering Explained and it did pretty good job explaining why other manufacturers overrate their towing capacity. Basically they design their trucks for 95th percentile of towers.

So it's fair to say truck is not hardcore tower.

It doesn't mean it's not safe for regular tower.

I'm a heavy PHP & Laravel developer and I speak for myself and a few close friends around my in my network who are like me. We all consider Laravel the reason we are still within the PHP scene and didn't move away. So in a sense I think it is true.

That said, the recent changes around Laravel (being bought out and becoming more and more commercial) is not something I (we) consider a good thing. Not necessarily a bad thing, but we all know that a OSS framework becoming commercial doesn't usually end well.

Seems quite comprehensive. I wonder if there’s a way to “escape” from the system. It looks nice for getting started but in practice at some point you’ll want programmatic access for e.g. advanced API features.

E.g. a well behaving system independent pipeline serialization could work. Didn’t find anything about this with a quick glance of the docs.

Edit: with a bit longer glance there is a plugin system that allows adding custom code quite easily.

I agree, and I agree with that recommendation.

It's the first one of his books that I read and I remember being completely in awe at his ability to write a novel as if he had a machine that allowed him to look into the minds of anyone at any time or place and then document what he saw.

That novel is about a totalitarian system, that of Trujillo in the Dominican Republic, and it's eerie how I started seeing the little details of human behavior that enable it in the story elsewhere later as well.

Given different bases (inevitable), it's easier to compare the Gini coeffs directly (though maybe no less misleading because of scale distortions)

From TFA:

The Roman Empire scored 0.46 and Han China scored 0.48. ... currently the Gini coefficient for the U.S. is 0.41.

That could help, as `.gov` can only be registered by the US government. But... a lot of the millennial and gen X generation have misguided beliefs about the trustworthiness of TLDs. Such as thinking `.com` is more trustworthy than `.net` under the assumption that it can only be registered by a real company.

I'm convinced the only responsible solutions are chip-only payment processors and conventional coin machines, as pricey as they are.

Let me put into personal context: I have loved PKD's work for almost 40 years now, and I think I have read all that I found from him or about him. This said, good prose is different from the one he turned out. Compare him to his friend "ELRON" - now he was a master storyteller. Compare him to - say - Stephen King. He's not playing in the same league, maybe not even the same game. OTOH they did not have what he had - he was. great writer in spite of his often poor prose.

While it's true a lot of people (particularly white Americans who've never experienced being a minority) will complain about minor things like just being treated differently, there are some obvious issues like housing discrimination, where you can be a incredibly high earner with a stable job, living in Japan for decades, and still be told no just because you're a foreigner. (To be fair, I think discriminating on visa length, time in Japan so far, income, job type is perfectly fine - just no reason to outright say no to all foreigners)

Small town living is kind of a different kettle of fish though. There can be lots of committees, local rules and association fees you're expected to take part in. Lots of these aren't really forced or regulated "by law", but someone from there is just expected to play into them. Lots of younger Japanese people and foreigners move there, learn about these and find them unbearable -and if you don't play ball you can be treated badly.

In rural areas though the main thing for foreigners is that you'll kind of become a town character "foreigner-san". Kind of unavoidable when you're the only foreign face many of these people will have ever met.

I think some foreigners have this dream if they assimilate enough people will just pretend they're not a foreigner anymore, which personally I think is unrealistic and silly - you are foreign. The truly happy people here find a way to integrate while coming to peace with the fact they're obviously different.

Yeah, I hadn't thought about it, but you're probably correct that height is the issue.

The Jochenstein lock that was mentioned is 7.8m and they barely cleared under it. That would be quite a tall load and then you have to add the height of the carrier. You can easily run out of options for something that tall and the German routes look like they use cloverleaf interchanges which could easily be obstacles.

> load fits in the 14' height limit for interstates in the state of Texas

There are special routes up and out from the Houston ship channel that use mostly diamond interchanges that could accommodate even something like this. However, the roads that this would have traversed in Germany are laughably small by Texas freeway standards so I can certainly see there being no way to get between the two points.

> As mentioned by another comms ter, the solution could be to find a way to separate the command and data channels. The LLM only operates on a single channel, that being input of tokens.

I think the issue is deeper than that. None of the inputs to an LLM should be considered as command. It incidentally gives you output compatible with the language in what is phrased by people as commands. But the fact that it's all just data to the LLM and that it works by taking data and returning plausible continuations of that data is the root cause of the issue. The output is not determined by the input, it is only statistically linked. Anything built on the premise that it is possible to give commands to LLMs or to use it's output as commands is fundamentally flawed and bears security risks. No amount of 'guardrails' or 'mitigations' can address this fundamental fact.

Pretty average dev here. It's not my profession but I do use it to make some of my living, whatever sense that makes.

Cursor is magic. Two massive use-cases for me:

1. Autocompletion of a copied function.

So I have some function, modX(paramX), and I need to duplicate it to modY(paramY). They're near enough the same. I love that I can copy/paste it, rename a variable or two, and Cursor then intuits what I need. Tab tab tabbity-tab later, job done. This might not be the most amazing use of AI but is sure as shit helps my RSI.

(I know I should abstract my functions yada yada.)

2. Generation of a new function where I have no idea how to start.

I tell the prompt what I need. "I'll give you a bunch of Markdown files and I'd like you to take the frontmatter properties and put them on an object then take each of the headers and its following content and put that in to this property on the object".

It'll do that, to 90%. I'll fix the 10%, making sure that I understand what it's created for me.

This would have taken me 4 hours. With Cursor it takes 15 minutes.

It's hyperbole, but like so often, there's a grain of it truth somewhere.

Also, like most things, Laravel is built on the shoulders of others. It sometimes makes hard things easy to access (ppl like this) and hides complexity away, clouding how things actually work (ppl don't like this).

I primarily use Laravel but like to think I code in a generalist if way as to not get stuck in its system.

Several kilograms. Children trigger the mines. So a large or a medium dog would usually too.

Windows actually had a decent built-in manual system with CHM, tooltips and whatnot. Even games could and did use it, like EarthSiege 2.

Back in the days when application developers stuck to the Windows-provided widgets instead of doing their own UI, it was wonderful. Symbols were consistent across applications, as were color schemes (IIRC, if you wrote your CSS correctly, Internet Explorer would pass these on to websites!) and behavior.

I miss these days.

Hear, hear!

Outside the corporate world's devices, I insist that my personal computing choices bring me either high confidence or personally useful knowledge/growth, or I will ban the product/company with malice. I banned APPL for foisting the full load of supporting older devices onto me, and MSFT Windows 11 is facing my personal banishment for kicking all older (but perfectly serviceable) hardware to the curb.

>When I say they have similar goals I mean they are both trying to sway public option to support their agenda.

Ok, but that's every politician (and many people as well). What their specific goal is matters. If one political party supports Israel 40% [4] and the other 80% then there's a difference. It's possible to support Israel and the Palestinians at the same time as well so it's not a clear "this or that"

>yield similar results.

If you are saying something like "Israel is still attacking Palestinians no matter who is elected" yes but to the same extent? What about aid to Palestine?

In 2018 Trump cut $200m worth of aid to them [1] then in 2021 Biden restored it [2]. I can understand if the issue is that neither party are going as far as you might want but that doesn't really make them same and not voting [3] doesn't make sense if you care because it can only make things worse for the Palestinians

Your argument reads like a general frustration with politics, which I get, but it still exists and will always exist. Not participating is the worse option imo.

The stock options are for common stock, right?

However investors that put money in get preferred shares (not common stock) right?

The tradeoff is not equal: taking less salary and receiving stock of less value seems risky to me. I can't imagine the employees discount is very good (those preferred shareholders don't want to be diluted).

Better sibling comment here with in depth opinion: https://news.ycombinator.com/item?id=43677084 : which answers my question:

when your options vest, is that you are essentially allowed to make an equity investment in the company with really unfavorable terms (ie ur not even getting preferred stock or any voting rights unlike your average investor).
by noodlesUK | 2025-04-14 08:15:31+00:00
I think one of the key things here is that those prices are denominated in dollars. If the real value of dollars falls, so does the value of those equities. If the nominal price falls, and the unit of measurement is falling at the same time, the actual value of represented has fallen more (potentially a lot more) than it seems like at first glance. There’s been a lot of inflation over the past couple of years, and it’s likely that this period will contribute even further.

I also think that the uncertainty hasn’t been fully priced in yet. I think that traders are hoping that this all blows over.
by ohgr | 2025-04-14 08:16:59+00:00
Firstly the market was heavily inflated by hyped shit in the last year so past performance was bad but the numbers went up. Then there’s the currency situation which masks a lot of the decline.

There’s a bunch of locked in shares and some of the high holding investment companies don’t give a crap as long as their AUM rank stays the same. They make money on fees still.

On top of that to sell you need buyers. That is not a problem for low volume traders but big holders won’t be able to shift lots. So the big ETFs, while the market position would be better to sell now, they can’t.

Gold isn’t a good bet either. What’s the betting when people ask for it, the answer is no.

There is no upside, just a slow deflation which isn’t as bad as some sensationalists expect. That isn’t a reason to crow about the current state. It’s like saying you’re cured because the first round of chemo was successful.

Yep, this checks out, they definitely need to lay off people, can't afford them.
Show HN: Devtron – Open-Source Kubernetes-Native CI/CD Platform
by satyampsoni | 2025-04-14 08:17:30+00:00
Hey HN We built Devtron, an open-source CI/CD platform purpose-built for Kubernetes. It combines deployment automation and application lifecycle management into one developer-friendly interface, so teams can ship faster without writing custom scripts or managing multiple tools. Most teams struggle with setting up a reliable CI/CD pipeline that works well with Kubernetes, ArgoCD, Helm, and GitOps, especially at scale. Devtron abstracts away that complexity, while still giving you control and flexibility. Key features: - Built-in CI & CD pipelines with support for GitOps using ArgoCD

- Native Kubernetes integration: RBAC, resource management, rollout strategies

- One-click Helm chart deployments and rollback

- Real-time observability with logs, metrics, and audit trails

- Multi-cluster support, secrets management, and security scanning

Please try it out: GitHub: https://github.com/devtron-labs/devtron Docs: https://docs.devtron.ai Website: https://devtron.ai/
