https://en.wikipedia.org/wiki/Co-channel_interference

One could argue that "interference" is not entirely a objective technical definition, but also subjective w.r.t quality of the service expected.

Also, in this scenario, if the two remotes were to transmit simultaneously, it is possible both could have received some mangled, unregonizable waveform. i.e. interference.

> Personally I think he is a very rich man who can pay others to do his R&D while he takes the credit for it.

I previously did not think this and gave him the benefit of the doubt. But it became more obvious to me that he constantly lies and takes credit when he started pretending like he was a great parent. There is simply no way you can be running several companies at once. And on top of that being a father to over 10 children from several different mothers living all over the place?

What’s especially crazy is even on this topic, you see the sycophantic comments thing. My guess is that he pays people to run social media bot campaigns or that he simply makes employees at Twitter do this.
Show HN: Echo – Local-first kindle-like reader with annotations and LLM chat
by tb8424 | 2026-02-01 21:57:46+00:00
Hi HN,

Long time lurker here. I'm kind of nervous to post this, but I built a tool for myself that I wanted to share with you.

Problem: I have A LOT of technical PDFs sitting around on my computer. I use ChatGPT a lot to deep-dive into the reading, but it was pretty distracting even with a split screen view, since I had to copy paste content from one window to the other.

Solution: A kindle-like reader that allows me to send context to a chat window and discuss more about it.

It has full portability through a sync file and uses your own API key.

Disclaimer: I'm a Product Manager and a Designer. This was 100% vibe coded in Cursor as a tool for myself, but I wanted to share it in case anyone might find it useful.

This hits the real problem: once agents execute code, “please don’t read ~/.ssh” is not a security control. Kernel-enforced isolation + tight allowlists is.
The secrets workflow (keychain/secret service → env → zeroize) is especially practical. Biggest thing I’d want as a user is very explicit docs on the remaining gaps (macOS read-permissive mode, procfs/env/subprocess behavior, and what Landlock can’t cover yet vs seccomp). If that’s clear, this could be a default wrapper for local agent runs.

This website has no more than a year in video presence in Youtube. It talks exclusively about Iran-only affairs that are of interest for foreigners. [It was started in 2017 and is mostly funded by Saudi money](https://en.wikipedia.org/wiki/Iran_International).

Sorry but we're going to need a more credible source than a propaganda site.

This is the stupidest nitpick, but it's not really Pavlovian conditioning (as mentioned in the last paragraph) but rather operant conditioning. Pavlovian, or classical conditioning is the triggering of a biological response after a neutral stimulus (ring a bell before feeding each time and the dog will salivate when it hears the bell even if there's no food anywhere nearby).

Operant conditioning is where the agent learns that an action produces an outcome and learns to perform (or not perform) certain actions to get the desired outcome.

I think it's worth taking the results seriously but not the proposed mechanism literally. Equating an internal perception which is loosely referred to as a form of "energy" with physical electricity/bioelectricity would be a mistake. Of course all sensations are indirectly the result of nerve impulses and bioelectricity, but you wouldn't say that someone experiencing tingles of say ASMR has literally received "energy".

It may turn out that you can consciously influence bioelectricity on certain levels (I mean you can certainly control motor functions, maybe you can modulate the current of injury [1] by thinking about a body part?). But you need to be clear about the level of abstraction: when you feel anxious are you going to literally attribute this to "clogged energy in your lower dantian", at the chemical level of increased norepinephrine and reduced blood flow to your stomach, or to simply your emotions?

A less fanciful way to say "experience deeper aspects of oneself, one part of which is a greater sensitivity to energy movements and corresponding fields" might simply be "greater sensitivity to emotion and bodily awareness". People do the same thing with therapy, discovering emotional/mental baggage they'd been carrying for a long time, and parts of the body they had been unconsciously tensing. When everything in our body is meditated by impulses and electricity, saying that you're "becoming more attuned energy" can be true but trite.

I think what you said is a healthy cycle, write dumb code -> figure out it doesn't scale -> add a bunch of clever abstraction layers -> realize you fucked yourself when you're on call for 12 hours trying to fix a mess for a critical issue over the weekend x how many time it takes you to get it -> write dumb code and only abstract when necessary.

Problem is devs these days start from step two because we're teaching that in all sources - they never learned why it's done by doing step one - they just do it that way because that's the way it has to be done.

Maybe this is just a skill issue on my part, but I'm still trying to wrap my head around the workflow of running multiple claude agents at once. How do they not conflict with each other? Also how do you have a project well specified enough that you can have these agents working for hours on end heads down? My experience as a developer (even pre AI) has mostly been that writing-code-fast has rarely been the progress limiter.. usually the obstacles are more like, underspecified projects, needing user testing, disagreements on the value of specific features, subtle hard to fix bugs, communication issues, etc. If I have days where I can just be heads down writing a ton of code I'm very happy.

Because EF's default behavior implements Unit of Work, a LOT of the complex transactional spaghetti ended up disappearing when we switched.

This aspect of EF is highly underrated for complex entity graph mutations.

EF makes the 90% use case easy and the 10% case possible with very little pain. The interceptors, global conventions, and other extension points are an enabler of complex behaviors that are still transparent to most of the team.

At the very least, every school, subject, and teacher should be obliged to conduct experiments during the school year -- A/B/C trials in which various forms of note taking are explored: handwritten, computer-typed, and neither.

Then see how it affects the kids' learning speed and retention of the various subjects. Then they need to compare notes with the other teachers to learn what they did differently and what did or didn't work for them.

Ideally they'd also assess how this worked for different types of students, those with good vs bad reading skills, with good vs bad grades, esp those who are underperforming their potential.

Sun and NeXT also sold 68k Unix workstations at the time. IMHO, The thing about Amiga was that it was not seen as a business machine. Commodore in general was seen as a home computer, and really one aimed at gaming first. AFAIK they didn't even have computers with the specs to compete with what Sun, SGI, HP, and others were doing.

It’s universal too; I know a lot of women, queers, POC, who don’t give one second of reflection to the reality 12-13 year old kids are sewing all the crap fashion they buy off Temu, or off the shelf at local shops who just import cheap crap to cash in on “buy local” memes.

They call it freedom and self determination. I call it co-dependency and learned helplessness. Labor exploitation.

Low skilled in their own right; they have no idea where to start solving their needs so never engage the motor agency.

Learned helplessness so a minority of humanity; first world affluents; out to avoid being responsible for themselves while they scold everyone else via TikTok.

Yes the politicians are awful for their own reasons but so many merely express concerns while carrying on without putting any real effort into solving their exploitative waves. Empty virtue signaling.

Most folks don't realize they're paying (up to) an extra 30% to Apple on everything they purchase in the app store. On top of an already exorbitant device price.

I'm sure you'd see more outrage if you had the app price listed without the fee, and then showed the fee below it/at time of purchase. It's another hidden fee.

I've used my own tool (https://pseudosavant.github.io/ps-web-tools/wordle-solver/) for understanding how many words are left after each guess. It'll show hints if you want them too, but they are disabled by default. I like understanding how my guesses reduce the word space well (or not).

It uses the list of all of the words that can be in Wordle, and there are so many words I can't imagine anyone guessing. And I come from a family with large vocabularies.

I assume they meant “five-over-one”, five floors of stick built (framed with dimensional lumber, not timber) apartments on top of a concrete and steel first floor.

Timber framing is something else entirely, you can construct buildings taller than six stories with engineered wood products.

> The mid-rise buildings are normally constructed with four or five wood-frame stories above a concrete podium, usually for retail or resident amenity space.

Nope. I found the tool in a web search a few months ago, and I've been filing bug reports and keeping up with the project for the past few months. I knew they were open-sourcing it and announcing it here today, so yes, I wanted to put my two cents in.

You're right, I don't post much here (or anywhere these days, really), and knee-jerk accusations like this are part of the reason. But sometimes I like to share things I find useful with other developers. I certainly don't make a living doing so, though.

Enjoy your day!

Thanks for sharing this. Real-time governance at the moment of consumption is exactly the pain point—most teams only notice the “token surprise” when finance forwards the bill.

Curious: how do you handle streaming responses and tool calls in metering (e.g., partial outputs, retries, multi-step agent loops)? And what’s the typical latency overhead you see in production?

Settings -> General -> Software Update -> Beta Updates

It's the same on macOS and iOS, pick "macOS Sequoia Public Beta" or the corresponding release for your device. Apple still pushes security updates for those releases, and I haven't heard of any problems with the kind of minor updates that ship late in a major release's lifecycle, so I think the risk of running this way is low. This kicks the can a year or two down the road, at which point hopefully there are better workarounds.

I would not be surprised if a lot of these humaitarian organizations come out and condemn the said strike u are mentioning rather than the IRGC actios. Also the Qataris, the Turkey, Russians, Chinese and Pakistanis and Palestinians are all supporting the IRGC killing Iranian civillians. All over the world we are seeing their actions. Also Obama,Biden they had same opportunities but they decided to help IRGC than actually fight them and take them out of power. There's a video of Obama admitting he made a mistake when he was in power. But still even now he's silent on Iran. That's why everyday, I lose a little bit more faith in humanity. Even the EU, France, Spain, UK they barely put IRGC as a terrorist organization now, they did NOT want to do it. Iranian embassies and their personel are active in all said countries... Just terrible politics ad terrible people in power if you ask me.

My friend and I labored over the word lists for our word game subletters.fun. We wanted the word pairs and at least one optimal path for each word pair to be from words on one list, which were simpler words that we would expect everyone to be familiar with. But players could use their own more advanced vocabulary to solve the puzzles on their own without feeling restricted. Then we bundled literally 10 years of unique word pairs into the game and shipped it.

At some point when you go to extreme lengths to pick the softest wording possible you yourself become an accomplice, they didn't "summon", that word is better for fantasies where they summon spirits or beasts like shai-hulud, here the fitting word would be "forced" as in "Iran government forces families of exiled journalists to stop any criticism against them"

I'm actually quite selective about what I post to Hacker News - I didn't submit this piece about Moltbook for example because there was already an active thread about it.

If you look at submissions from my domain on https://news.ycombinator.com/from?site=simonwillison.net you'll see most of them weren't by my simonw user - I generally submit things myself 2-3 times a month, and only things I deem to be "Hacker News worthy".

Pitch levels are important enough in English that native speakers spontaneously develop ways to write them down, even though the standard written language has no way to indicate them.

However, they operate at the level of the sentence rather than the individual word, which sets up a conflict if an English speaker wants to learn Chinese.

The most common uses of pitch in English are to annotate the grammatical structure of a sentence, making it clear which words belong together in larger phrases, and to mark yes/no questions.

English does have one clear example of lexical tone, the "I don't know" word, which is pronounced very similarly to the Mandarin pinyin éēě. (If pronounced with the mouth open. With the mouth closed, it would be more like 嗯嗯嗯 in the same 2-1-3 tone sequence.)

Interesting points, especially about the challenge of correlation. I guess we could remove DNA and see what happens ...

Somehow the machinary is passed down: Do we know of another mechanism besides DNA that is self-perpetuating? Is there any living creature without it? Prokaryotes (bacteria) even have DNA.

Or is there a way to do it without self-perpetuating mechanisms? Is that logically possible? Some machinary might be perpetuated by other machinary, e.g. the chemical might recreate the electrical, meaning it's not self-perpetuating. But that's not different than DNA: DNA itself isn't the machinary, but its self-perpetuation is what recreates other parts.

I suppose some parts of the environment are consistent, such as sunlight, air, water, and heat, but the environmental stimuli must trigger something that is already there.

That's a perfect example of making it overcomplicated, just in the FP direction.

C# uses exceptions for error handling. It has it's own control flow primitives. C# developers know how to work with it, everything else uses it. Why would I want to pull in a randos GH DSL and types to pretend I'm writing F# when I can just use F# that has first class support for this ?

If I could go back in time and change what courses I took for my CS degree, it would be the exact opposite.

I wish I'd gone more into theoretical computer science, quantum computing, cryptography, and in general just hard math and proofs.

I took a few such courses and some things have genuinely been useful to know about at work but were also mind-expanding new concepts. I would never ever have picked up those on the job.

Not to say the practical stuff hasn't been useful too (it has) but I feel confident I could pick up a new language easily anytime. Not so sure about formal proofs.

No smokers in my neighborhood, but people use their goddamn fireplaces too much and it’s kinda impossible to get fresh air in winter evenings and often during the day. Not sure how to train them. And unfortunately, there are too many. Burning wood should be forbidden in residential areas. It’s similar to smoking in restaurants, except you can’t escape them.

There are several reactions to the 'I don't want to pay taxes' so I'll pick this one and respond. I hope you read the rest of the comment. I don't want to pay taxes because who does? Ever? But we -need- to pay taxes for programs that work because the alternative, massive social costs and damage to society, are far worse. So, sure, I don't want to pay taxes for social programs but I admit the need to and therefore I want the most effective, evidence based programs we can find. We need value for the effort and that involves doing research to figure that value out. If a program like this efficiently reduces the problems associated with homelessness I am all for it.

As to what I would actually want to pay taxes for it is to build new things and achieve new things as a society. I never want to spend money on 'fixing', it is needed, it has to happen, but that doesn't mean I have to like it. Building new things however I am 100% for. Get us to space. Find new particles. Help foster the arts. That is what I want my taxes to go for. So, yes, fund things like this if it is effective because we have to but you won't get me to say I want to spend money one this.

I wonder how AI can disrupt this nasty business by teaching users how they can self-host much of those services and save $$$. Let's face it: for the normies out there, the idea of having "your own iCloud" is still daunting (albeit very much possible).

Can AI level the playing field between users and greedy firms like Apple?

I think you are the one that casting stones from a position of comfort rather than seeing and condemning evil for it is evil, same as all these NGOs and organizations. They could put themselves in danger its literally doctors without borders made to help the unrepresented populations. They were in Palestine and keep being against Israel, but can not say a word against IRGC? what are you trying to accomplish by your comment? I am doing what I can for my friends and family in Iran who many of them have had dangerous stuff almost getting killed by IRGC.

> Being able to pronounce the basic sounds correctly has a huge impact on how native speakers perceive your language skills, even if you're not very advanced in the language.

That's true, but it counsels against trying to develop better pronunciation early.

If you sound like a native despite having just started to learn the language, people will naturally conclude that you are mentally retarded.

The word summon comes from Anglo-French somundre and Old French somondre (or semondre), meaning "to call, send for, or notify". It derives from the Latin summonere, meaning "to remind privately, warn, or hint to".

To summon is the correct word in this case. The fantasy meaning comes from thee power politics between one that summons (usually: a king) and the one being summoned (usually the serf).

I'd recommend Vali Nasr and Payam Mohseni's works.

But frankly, Iran as it stands today is structurally similar to pre-1976 PRC, and requires an Iranian "Deng Xiaoping", but the only reason Deng even got as far as he did was because the Sino-Soviet Split made the PRC an attractive partner against the USSR and because it took someone with the stature of Mao to host a "Nixon in China" moment, which made partnering with America politically palatable.

The key economic and political institutions in Iran (Army, IRGC, Bonyads) would need to be incentivized to flip to being pro-EU and pro-America in order to sustain the semblance of democracy and secularism because frankly, Russia, China, India, portions of the Gulf, and much of ASEAN is fine working with Iran as it stands today because it is a critical regional power.

Turkiye, the UAE, Qatar, KSA, and Pakistan are probably the best regional players to push a gradual re-opening of Iran.

Upton Sinclair coined the oft-cited maxim “It is difficult to get a man to understand something, when his salary depends on his not understanding it.” I propose a corollary: It is difficult to get a company to see that certain of its core competencies[1] are in severe decline[2] when the company is making more money than ever.

LLMs will stop being trained, as that enormous upfront investment will have been found to not produce the required return. People will continue to use the existing models for inference, not least as the (now bankrupt) LLM labs attempt to squeeze the last juice out of their remaining assets (trained LLMs). However these models will become more and more outdated, less and less useful, until they are not worth the electricity to do the inference anymore. Thus it will end.
