Hello! Awesome work on your hashing by the way!

When iterating I first tried to make fast_loop as random as possible by trying all possible rotational values and then having each option tested in PractRand 1000 times from 256M to 8GB. There was a wide range of performance by rotation. 47 was the best (for the GR constant) and resulted in the most tests being passed. The goal was a stronger than normal core for the PRNG that could feed actively into mix.

I found the multiplication to be necessary for passing PractRand and BigCrush with the state mixing as posted.

I had a variant which assigned mix as rotate(mix,constant) + (mix^fast_mix). That would pass cleanly with mix directly outputted (with no multiplication) - but I couldn’t get Z3 prover to show injectivity so I decided to go with the posted route.

Well their press releases indicate long term support and then they cancel the projects. This _has_ to have more serious consequences (on businesses mostly, but consumers too) than you are implying. This sort of thing naturally effects consumer/brand loyalty. With such a clear lack of focus on any one solution, why would anyone trust Google going forward with their new products/services?

This is the end result of trying to run your massive corporation like some kind of start-up incubator. No wisdom or strategy, just throw shit at the wall and see what sticks.

The problem I've always had when forwarding addresses, at least to my Gmail, is that Gmail seems to credit all forwarded spam to the forwarding address, so if your forwarded email gets a lot of spam, it quickly starts sending a large percentage of even the legitimate forwarded email to spam. Is there a solution to that issue?

Instead I've taken to using the pop download option, but that has its own issues (mostly the long delay between downloads).

It's not pure security theater, there are a few clear gains for those who care about such things:

* Naive screencaps are much less traceable to the leaker than a naive photo is. Yes, someone can strip out EXIF data, but we've seen over and over again that they generally don't. And even without EXIF a naive framing on the photo is more likely to expose information about the location or identity of the person who took it.

* A photo of a webinar is going to (barring serious postprocessing) look much less official and be less legible than a screenshot, so the use cases for illicit captures are going to be fewer. Few people are going to try to take a phone photo of the top-secret meeting and use the slide in their next team all-hands, but many might forget the rules and than snap a screenshot really quickly for later use.

* Just having the ability to block the easy method of screen captures helps avoid cases where the person doing the capturing isn't actively malicious, just ill-informed. If a normal employee attempts a screenshot and is reminded they're not supposed to do that, they're not going to pull out their phone to take a photo, they're going to say "oops" and move on.

Yeah, there are threat models that won't be stopped here, but most of corporate InfoSec is wrapped up in protecting against pretty lame threat models that would benefit from this—mostly uninformed/ignorant employees screwing up without intending to be a threat.

> If you were in charge, how would you do it

TBH I'm not sure. My charitable interpretation is that the US government said they would try but never did, or at least not successfully. At least Trump's government is willing to try in broad daylight, and Vance explicitly called out that it is a pipe dream that a nation could enjoying drawing boxes in air-conditioned offices and hope that we have technology superiority forever, as innovation only came from doing. So, I'm willing to give them benefit of doubt and wait for months if not years to see how things pan out.

> Are there any incentives to make household items here?

My naive view is price is the incentive. True capitalism means when price is too high to have space to arbitrage, the investment will pour in or the bootlegging will proper. I hope it's the former.

> If the plan is to use 100% automation and robots, that defeats the purpose of creating jobs, right?

My optimistic view is that we would create a lot more jobs in different categories if we can achieve certain level of automation.

P.S., super successful people like Balaji basically said that it's hopeless now. The western world can't bring manufacturing back because we don't have talent or know-how or great workforce any more. That saddens me greatly. China didn't have talent or know-how or great workforce 20 or 25 years ago. If we read the newspaper then, we would see everywhere that western talent and professionalism were the envy of the entire nation. Most people thought owning a car was a pipe dream, let alone making their own AEW or 5th-gen fighter jet. It was Japanese, Taiwanese, Americans, and Europeans who brought investment and know-how to China to boostrap the great nation. Yet now we throw the towel and thhink we can't rebuild out talent? Our fate is becoming a neo-colony?

Context for others: Standalone computer monitors per se did not exist at retail in 1977. The only choices were either televisions, or displays for security-camera systems such as the Sanyo VM-4209 <https://collections.vam.ac.uk/item/O1461694/sanyo-vm-4209/>. The latter, because of its high quality and perfect size for stacking on top of the Apple next to disk drives <https://www.reddit.com/r/VintageApple/comments/3snpqd/i_foun...>, became the iconic Apple II monitor of the early years until purpose-built computer monitors from Amdek and others, as well as Apple's own Monitor III <https://en.wikipedia.org/wiki/Apple_Monitor_III>, became widely available.

Yeah you're right, and ultimately it's important to discuss and bring up.

Just because I can invent a reason someone else can write it off...well, that doesn't shed any light either.

It's clear you can always find at least 15% of some group who will find a reason to write anything off.

(I'm basing that off of some stats I saw re: moon landing denial recently)

> In 2026, a sphere nine metres in diameter and weighing 400 tonnes will be submerged off the coast of California at a depth of 500 to 600 metres. It will have a storage capacity of 0.4 megawatt hours (400 kWh), enough energy to power an average household for several weeks.

What is this going to cost? From a quick search, Tesla Megapacks are now about $250/KWh. With battery costs still falling steadily, those might be considerably cheaper by the time the first 9m sphere hits the water.

And with all the recent anchor-dragging incidents, how many countries would be eager to have their energy storage located far off-shore?

I had a Dragon32 in the early 1980s. This had a (for the time) good keyboard, a terrible display, and was only uppercase. I bought it because I was interested in the 6809 processor (addressing modes gone mad!). But I think some effort between Tandy and maybe Dragon (the Dragon was based on the Tandy Color computer) things could have worked out better for both.

Those easy times of the 50s were created from the pains of the 30s and 40s. 25% were unemployed in the early 30s.

If you wanted to go back you would have to kick women and minories out of the workforce so a man could earn double and have a percentage of young able bodied men killed or broken a generation before (through a war) before to get that demand where a highschool dropout who becomes a mailman can buy a house for a few thousand dollars.

Existing built home prices are going to go up in value if your society growing expanding. If you want declining home prices you need to reduce people/demand. The problem today is everyone wants to live in the biggest cities mostly because of jobs and everyone wants to setup a business because greater selection of employees. If the work from home movement succeeds this can break one of the pillars of why people need to be in big cities and cheaper houses can be built elsewhere.

We’re sitting here arguing about the obviously incorrect title and America is burning, so we are speaking about the wrong thing. It’s irrelevant whether it’s 70 or 0 percent, we’re still fucked. Discussing the issue of 70 vs 0 percent isn’t going to solve how fucked we are, so it’s a technicality.

There was a third-party Machine Code Monitor cartridge. Don't remember who made it. You could write code, as well as view it, or debug it.

I used the 6502 manual. I was taking Machine Code in school at the time (tech school -not "proper" school), and had learned how to trawl the tech literature for guidance.

GitHub is not a small place.

Remarkable because he hasn't been debunked, and IBM's attempts to have the lawsuit thrown out of court have failed. IBM has also tried to scrub the video from YouTube it seems, the Twitter link is the only one I could find.

>But if you want to claim that when people working at corporations hear about goals to increase representation that they just decide to violate Title 7 at scale, you've got some splaining to do.

The various lawsuits, some that have gone to the Supreme Court, have shown this type of discrimination against Whites, Asians, and males has been occurring at scale.

>Kay's view of OO is pretty different from what we understand of OO today

Indeed, in his own words, from 1998:

https://wiki.c2.com/?AlanKayOnMessaging

He also gave at least two conference talks where he explained how his view of objects sending messages was in line with his background in molecular biology: he thought of the objects like cells sending messages via exchanging various chemicals. I don't have either on hand, but I believe one time he shared this was in an interview with Joe Armstrong.

It's not this simple. A lot of people revel in suffering because they have a faulty mindset that good things can only come from bad things. Meaning, success comes with blood, sweat, and tears.

This is not true, generally. There is such a thing as free lunch. Not everything must be a battle, and not every battle has a winner.

Some people lean into work because they believe that by sacrificing they will discover the key to happiness. So they sacrifice things that feel good, like spending time laughing with friends or maybe delicious food. In short, they shrink their lives, purposefully removing the good parts. Some go so far as to remove good parts for absolutely no gain. Maybe they're gluten-free, but they're not gluten intolerant. Some are even purposefully lonely in some extreme sacrifice of human nature. Almost like monks or cardinals - they believe if they sacrifice something so fundamental, like sex or love, that they will achieve something other's cannot.

The truth is a lot of that sacrifice will be for nothing. Sometimes the right choice is doing something stupid, or doing something unproductive.

Indeed, here's a email from Alan Kay about how his perspective is about "messaging" between objects:

https://lists.squeakfoundation.org/pipermail/squeak-dev/1998...

(edit: derp, this is directly cited in TFA)

Also, I loved this interview/discussion between Kay & Joe Armstrong, inventor of Erlang, where the topic comes up again (because Erlang is also a lot about messaging between agents)

No, not absolutely all situations. But take my situation - I live in Berlin and I use my car less than once a month. A major reason to drive is to have a car at the destination. I've also had streaks where I drove to the supermarket every couple of weeks, but I haven't done so in months. Main upside is that I can buy whole cases of beer and a bunch of other drinks and heavy stuff, less trouble carrying. Otherwise, the closest supermarkets are about five minutes by foot.
Show HN: iOS TV Show tracker app (uses TMDB API)
by andrewfromx | 2025-05-10 23:40:17+00:00
Hello HN, we are a two person team building showffeur!

The name of this app is chauffeur but it's for TV Shows so, great name right? There are a lot of iOS tv tracking apps but we tried to combine all the best features into one really good app. We have 90 available seats for internal testflight invites.

https://andrewarrow.dev/2025/may/beta-testers-wanted-showffe...

Features include:

- Queue shows you plan to watch next

- Mark episodes as watched to track progress

- Follow new episode air dates for running shows

This app came about because I (andrew, developer) got back into Swift coding. Haven't done it for years but wow, it's nice to be back in it. And jason (PM+designer) was wanting a better app from all the ones available. We teamed up and what a fun passion project this has been. We worked together years ago for a big company, stayed in touch as friends, but this is our first time working together on a side open source project. Tons of fun. And I've really gained ALOT of respect for what a good PM+designer does. I'm your typical developer who thinks, eh, I can just do the all the roles. But wow, I am humbled by how much better jason has made this app.

If you would like to beta test, see link above. Thanks!

> Again further stating the obvious here but this is the _desired_ effect.

Hanlon's Razor suggests that your statement is incorrect.

Tariffs need consistency and stability to be effective rather than purely disruptive.

You can see this in how much more effective the countries applying tariffs against the US are handling things. Since they are applying tariffs and leaving them in place, the incentives are working properly, and they are disconnecting from the US businesses.

In the US, by contrast, businesses are either shutting down or holding their breath in the hopes that tariffs will pass.

Having used alternatives to a few of their products… I’ll accept part of that list.

Gmail is well below mediocre, it’s so sluggish and unresponsive even on fast hardware. Compare with fastmail; it’s hard to go back.

The search engine consistently gives me pages of blog spam before a useful result. Eg Kagi is dramatically more useful despite having a tiny fraction of the resources to work with.

An underwriting loss, when you specialize in a very specific risk, is not something you can later make up with volume. They still have to pay for overhead, acquisition costs, etc. And customers have little loyalty for auto insurance. If they only join in the first place because your prices are lower, they will leave as soon as you raise them.

Most insurance companies would be very concerned this type of concentration of risk, and having no underwriting pricing advantage. At best you can say Tesla wants their insurance to be a loss leader to encourage sales of the cars themselves, and to prevent the risk of other auto insurance companies declining to cover their models due to high repair costs and their customers having no insurance alternatives.

It is very deep in American culture. I think this sums it up when Tocqueville was talking about America not having a true aristocratic class, circa 1830s

“In a democracy private citizens see a man of their own rank in life who becomes possessed of riches and power in a few years; this spectacle excites their surprise and envy, and they are led to inquire how the person who was yesterday very equal is today their ruler. ” ― Alexis de Tocqueville, Democracy in America

In 21st century America, the internet and social media has poured huge amounts of gas on this fire that was already burning quite hot for a long time.

Even in my own lifetime, the character Gordon Gekko in the movie Wallstreet has gone from a villain to pretty much the aspiration and hero of most high school seniors. Greed is good, greed make number go up.

I agree. The search index is great, the presentation is shitty.

It doesn't work against which threat model?

Yeah, if you've got corporate espionage going on this isn't going to stop someone from lifting your slides and taking them elsewhere. But the most common culprit of corporate information security violations isn't a spy, it's a well-meaning employee who didn't hear, remember, or correctly interpret the request to not record the meeting.

Blocking the most common way in which this kind of well-meaning but ill-informed employee would break the expected security rules does work. It's just getting flak here because people are imagining a much more exciting threat model.

Honestly, I feel like people are subconsciously aware that Google is trying to bludgeon them into getting YouTube premium, and they're simply sticking it to Google rather than giving in. Google's gone through:

- one skippable 5s ad

- two skippable 5s ads

- one unskippable 5s and one skippable 15s ads

- aforementioned or two 15s ads, one skippable

- two 15s unskippable ads

- removed the prerenderer 'skip' button to make it more difficult to immediately skip

- removed the ad amount indicator and precise length indicator (now just a bar) to psychologically drive people into sunk cost feelings

God knows what they're cooking up next.

And for large swathes of content, there is no alternative to YouTube.

> Even a few years on, I'm missing Optane drives because there is still no functional alternative...... they would have created a set of enterprise customers who would still be buying the things in 2040.

I guess many on HN are software developers looking at Optane.

In reality Optane was simply not cost effective. Optane came at a time when DRAM cost / GB was at its peak, the idea to developers could have slower DRAM that is non-volatile is great, until they realise slower DRAM causes CPU performance regression. Optane Memory, even on its roadmap in future product will always effectively be another layer between DRAM and NAND ( Storage ). And they could barely make profits when DRAM was at its peak. I dont think people realise there is near "4x" price difference between the height of DRAM price in ~2016 ish to ~2023.

In terms of Optane Storage, it was again at NAND's cost /GB peak and it was barely completing or making profits. Most would immediately point out it has lower latency and better QD1 performance. But Samsung showcased with Z-NAND, which is specifically tuned SLC NAND you can get close enough performance, far higher bandwidth and QD32 results, while using much lower power. And has a reliable Roadmap that is alongside the NAND development. Even Samsung stopped development of Z-NAND in 2023.

The truth is the market isn't interested in Optane enough at the price/ performance and feature it was offering. And Intel's execution for Optane, they have either over promised ( as they do in that era ) and fail to deliver on time or they are basically lying about the potential. And fail to bring down cost of fabbing it, which they blame Micron but in reality it is all on Intel.

The industry have also repeatedly stated they are not interested in a technology that is single sourced by either Intel or Micron. Unlike NAND and DRAM.

Intel was giving away Optane and pushing to Facebook and other Hyperscaler. But even then they couldn't even fill the minimum order for Micron and had to pay hundreds of millions per year for empty fabs.

> The best thing that happened to me at that time was not being able to afford a floppy drive.

Well, you were lucky in more ways than one, since the Commodore 1541 floppy drive is legendary for being both more expensive and slower than other 8-bit floppy hardware. So much so there was quite a market in software and hardware hacks to improve performance (the reasons why it was so bad have been written about extensively (including by its designers) and are a fun read).

> My friends who had one just played games.

Initially I didn't even have a tape cassette recorder and just had to type my programs in again. At least that made only having 4K of memory in my 8-bit micro not a problem :-). I guess it's a good thing you didn't know there were commercial games available on cassette tape or the world might have one less programmer!

The US has a wealth tax that predominantly affects the middle class - property taxes. In some states, like mine, it can be 10K+ a year for a typical home!

It doesn't really discourage people from building their wealth and buying homes. It does a tiny bit - I've heard people say they rent to avoid property taxes. But barely.

So, if the middle class who do not have a lot of wealth can deal with it, I would imagine the wealthy can, too. Or, maybe they can't, because they have so much more mobility.

He really didn't say a lot there, so I am wondering if it merits an HN thread. Maybe over time it will be clearer what he means, or what he thinks on the topic. I don't feel like I can read a lot into that one piece.

Edit: why the downvotes? It's true he said very little, and it will take more time for him to elaborate on a position. I guess you guys hallucinate more than a bad AI. As an example, I saw a commentary that the prior Pope Leo's Rerum novarum was not really that influential until a few decades after it was written. This stuff happens on long timescales.
