Can you explain how using Postgres for a job queue, ideally using something like pgmq[0], is in "you better know what you're doing" territory, while using Redis isn't, and without talking about performance?

Redis is fine as-is and I'm not suggesting anyone should rebuild the whole thing in Postgres, only that if they want a specific thing that Redis can do and they already use Postgres, then they might be able to do the same thing in Postgres with less effort and thus avoid losing atomicity and consistency and any other properties of Postgres that they find desirable.

Posting from another account.

I'm aware that extensions exist now, like present, which make it possible to send buffers, similar to how Wayland operates, so you don't have to do things the primitive way.

However, to claim to speak the X protocol, you still need to support the older functionality, that's what I mean by a tremendous amount of functionality to support. The moment you get rid of that old functionality, you've essentially created a new protocol, which is what Wayland is.

How is that point nonsense? I don't want to see X go, but I don't think it's reasonable to prevent progress.

In English, x or time(s) after a number marks a "unit" used by various verbs. A 10x increase. Increase by 10x. Go up 10x. Some of these verbs are negative like decrease or save. "Save 10x" is the same as "divide by 10". Four times less, 5 times smaller etc. are long attested.

It may come as a surprise to some that a lot of industrial computer vision is done in grayscale. In a lot of industrial CV tasks, the only things that matter are cost, speed, and dynamic range. Every approach we have to making color images compromises on one of those three characteristics.

I think this kind of thing might have real, practical use cases in industry if it's fast enough.
Show HN: Send USDC via Email

It's time for a better Venmo/PayPal...

One that is globally accessible, makes you money and takes a cut of the profit instead of screwing you with fees and bad conversion rates

I made the iOS + web app and I'm handing it to you

Send USDC via email

Btwn Friends is an open-sourced PayPal/Venmo alternative that let's you send stablecoins to anyone's email without them being on the app, having a wallet or knowing about crypto.

Here's how it works

Every P2P payment app makes you create an account, save 12 words, link to a wallet app, KYC, transfer gas tokens...

It's intimidating and too much work

Your friend just wants their $20 back. They don't care about "decentralization"

Here you sign in with your email and a one time use password (OTP)

That's it.

You just logged into your wallet or created one. no wallet app, chrome extension, seed phrase, or crypto knowledge.

Your wallet is created automatically by Coinbase Developer Platfrom

To send money, you just need an email address.

Not a wallet address or an ENS name. Just an email. Enter: friend@example.com → $25 USDC → Send

That's the entire flow.

The recipient gets an email: "John sent you $25" They click the link → Sign in with email → Funds appear.

They don't need to: - Set up a wallet - Have ETH for gas - Know what a blockchain is - Copy/paste addresses

If your friend is on the app → money goes straight to them

If they're not → money goes into an escrow

When they sign in with email & OTP, they prove they own that email.

Escrow releases funds automatically. They see their balance before the dashboard loads.

You can build onchain apps without forcing users to "learn crypto"

Between Friends is built on Base (Eth L2) using a basic escrow smart contract and is powered by Coinbase Developer Platfrom's Embedded Wallets (smart accounts) and Paymaster

I've done most of the job for you and left notes on what's left.

Coinbase Developer Platfrom's Embedded Wallets already give you ~%4 rewards on balance out the box

You can make more for yourself & your users leveraging onchain tools like @MorphoLabs, @MoonwellDeFi, @superformxyz...

Every time I fly from SFO, there’s a face-tracking camera that takes your photo after you stand up close to it. There’s definitely some sort of data harvesting there and there’s no opt out that I know about.

I also have Clear, which was voluntary but certainly collected my biometric data years ago.

I also have Global Entry, which has a similar scanning tech to point 1.

I just don't know that I see it running any better for the vast majority of processes that I could imagine running on it. Was literally just transcoding some video, playing a podcast, and browsing the web. Would this be any better?

I think that is largely my qualm with the dream. The only way this really works is if we had never gone with preemptive multitasking, it seems? And that just doesn't seem like a win.

You do have me curious to know if things really do automatically pin to a cpu if it is above a threshold. I know that was talked of some, did we actually start doing that?

> Multimodal models aren't really multimodal. The images are mapped to words and then the words are expanded upon by a single mode LLM.

I don't think you can generalize like that, it's a big category, not all multimodal models work the same, it's just a label for a model that has multiple modalities after all, not a specific architecture of machine learning models.

It seems like you're responding to a question about training by talking about inference. If you train an LLM because you want to use it to do sentiment analysis to flag social media posts for human review, or Facebook trains one and publishes it and others use it for something like that, how is that doing anything to the market for the original work? For that matter, if you trained an LLM and then ran out of money without ever using it for anything, how would that? It should be pretty obvious that the training isn't the part that's doing anything there.

And then for inference, wouldn't it depend on what you're actually using it for? If you're doing sentiment analysis, that's very different than if you're creating an unlicensed Harry Potter sequel that you expect to run in theaters and sell tickets. But conversely, just because it can produce a character from Harry Potter doesn't mean that couldn't be fair use either. What if it's being used for criticism or parody or any of the other typical instances of fair use?

The trouble is there's no automated way to make a fair use determination, and it really depends on what the user is doing with it, but the media companies are looking for some hook to go after the AI companies who are providing a general purpose tool instead of the subset of their "can't get blood from a stone" customers who are using that tool for some infringing purpose.

It’s $200M notional.

To make the math easy, let’s assume it’s a PLTR 200 strike put expiring in February 2026. Each put is $20,000 notional so 10,000 puts would be $200M notional.

Feb PLTR 200Ps are trading for $3k or so each, so it would be $30M in premium for $200M notional with an in-the-money put.

If a market maker sells one 200P (52 delta) they are functionally long 52 shares, so they hedge by selling short 52 shares (or selling a call with 52 delta). If he has 10k contracts then the MM that sold the puts would be functionally long 520,000 shares and would need to short that many deltas to hedge.

Avg recent trading volume for PLTR is ~50M shares a day; 10,000 (50 delta) puts is roughly equal to 500,000 shares and be about 1% of a day’s trading volume.

Tl;dr: He’s holding 10k to 50k put contracts, depending on the moneyness and expiration date.

Unrelated to the article, but the scope ID in IPv6 addresses is super useful for the networking software I write.

The socket API for IPv4 requires a strange ceremony of calling if_nametoindex to map an interface name to an index then setting IP_BOUND_IF in order to bind a socket to a particular network interface. (Sorry, this only works on BSD and Mac OS; Linux instead uses SO_BINDTODEVICE for whatever reason).

When you don't supply a network interface, the OS "helpfully" guesses an interface, and that interface is usually the wrong one for multicast and broadcast packets.

I made a PXE boot server in Rust recently, and I lost at least 30 minutes of my time figuring out why DHCP responses wouldn't be receieved by an EFI client. The problem was that 255.255.255.255:68 is inherently ambiguous when multiple network interfaces exist.

In the case of the IPv6 API, you have to specify the interface up front (e.g. ff05::1:3%en0) or else you won't even be able to send a packet. I used to find this design tedious, but I prefer writing scope IDs explicitly in an address rather than having libc (or my own code) iterate over a linked list provided by the kernel to get an integer then supply that integer to a setsockopt (and remember that Linux has a quirk here).

Depending on the metric (e.g. MAU, DAU, web impressions etc) X is generally down about 3-20% since Elon's takeover. Seems fair to say X is a 'break even' investment at best.

It will be extremely interesting to re-visit this thread in 10 years. X is currently a gateway for promoting Grok (with 11-figure DAU potential), and X is acquiring financial licences in US states, with a view to becoming an 'everything app' (something which the East seems to have - in the forms of wechat, Grab - but the West weirdly doesn't). If X can be the West's first 'everything app'.. trillion+ dollar valuation isn't out of the question.

As a US citizen, you likely have your photo in a state or federal database somewhere from getting your ID or driver's license.

Depending on your job, background check history, or interactions with the police, your fingerprints might be in a database somewhere.

If you fly, your facial image/photograph/video is held by TSA and also as part of the REAL ID program.

So there are some biometrics that the government has of us, but clearly the article is describing a huge increase in not just the kind of biometric data collected, but also the kinds of people who would be required to give it up.

Laura Loomer affecting staffing decisions because one of their stooges isn't the right flavor of corrupt and incompetent for her is what a clown show is. Pretending this deserves the same dignity as a competent and good faith administration would be the ultimate participation trophy.

Figuring out how to do db backups _can_ also be fairly time consuming.

There's a question of whether you want to spend time learning AWS or spend time learning your DB's hand-rolled backup options (on top of the question of whether learning AWS's thing even absolves you of understanding your DB's internals anyways!)

I do think there's value in "just" doing a thing instead of relying on the wrapper. Whether that's easier or not is super context and experience dependent, though.

Maybe you're too young to remember the kind of vibe and optimism that people rode in the 90s.

Felt like everything was going to be better, like we humans were going to be better. More peace, no apartheid, no Soviet union, removing borders between countries in Europe, tech felt like a way to connect us.

In fact, I invite you to re read your entire post. You post achievements in conveniences as major milestones for human progress, but...people have never read as little as they do today, never went to so few concerts as today, or the movies and the average adult in US spends less than 4 hours socializing (including both family and friends) per week, that's less than half the quote of the 90s which was already less but not as significantly.

100%. Let’s not let partisanship distract us from the omni-presence of the military industrial complex and the authoritarian bent of everyone who’s been in power in the US over the last several decades. Dems will tinker around the edges to make it more palatable, but there’s still: black sites, torture, drone strikes, unjustified wars, installing of puppet governments in sovereign nations, abuse of the commons for private profit and an absolute hunger for every scrape of your data to monitor and manipulate you no matter who is in the White House.

If I have to choose between voting for pro-corporate neoliberalism or fascism 2.0, I’ll vote the former, but that’s basically just asking which speed you’d like quality of life to erode for the average person. I’d really like a couple more options on the ballot please.

The YouTube video is slick but misleading. It repeats a pro-nuclear line that the LNT model is “anti-science,” citing a few industry-aligned papers from niche journals. In reality, large independent studies—INWORKS (BMJ 2015, 2023), the Life Span Study, and BEIR VII—all confirm cancer risk rises linearly even at low doses. Hill is not a radiation biologist. The myth isn’t LNT—it’s that YouTube can overturn seventy years of evidence.

> Building a sub 512KB website that satisfies all departments of a company of non-trivial size; that is hard.

I’m all for minimalism and have a much lower target than 512KB for some of my work. But I think the goal of having the entire site in 512KB is a little strange; someone might have a 511KB SaaS SPA app while others struggle to have 51 10KB pages. That’s not the same.

> running and managing numerous DBs, k8s clusters, ci/cd pipelines and stateless container systems is simply impossible with a team of 1-2 people

Then don't. If your team and budget are small enough not to hire a sysadmin, then your workload is (almost certainly) small enough to fit on one server, one Postgres database, Jenkins or a bash script, and certainly no k8s.

> What would you even call their socioeconomic system? They're not exactly doing neoliberal capitalism, their government is far too involved for that. They're not socialist, they've got free enterprise galore. The autocracy+militarization+heavily meddled with big business thing most resembles fascist states

It's just State Capitalism, isn't it? Like China. A market-based economy with free enterprise, but no illusions of egalitarianism or democracy, enables the state to step in and manage and direct the market with effective regulation. In a democracy the state can manage this for a time, but eventually a private entity or group of entities leverages their power to influence law and co-opt democratic power, so the market starts steering its own regulation and you end up with fascism as a means of population control or a Russia-style cleptocratic oligarchy. We have not yet figured out how to sustain democracy + capitalism, if it's even possible.

I worry that most will see the rise of countries like Singapore and China and the relative decline of the US/EU and conclude that democracy is a failed project all together.

This is the big one.

In 2006 when the first EC2 instances showed up they were on par with an ok laptop and would take 24 months to pay enough in rent to cover the cost of hardware.

Today the smallest instance is a joke and the medium instances are the size of a 5 year old phone. It takes between 3 to 6 months to pay enough in rent to cover the cost of the hardware.

What was a great deal in 2006 is a terrible one today.

It's incredibly disappointing to see HN users flag these stories while the admin is directly admitting to starving people for political gain. It's something that directly and materially impacts me, a tax-paying citizen who has to now spend money out of my savings to support my parents so that they don't starve, who also paid taxes their entire life for these programs to exist and help them.

It's something I literally cannot put my head in the sand to ignore. I would strongly advise others do not ignore it either.

I feel the same! One bit of advice has helped me take better advantage of those small chunks of time- "Park facing downhill." I don't remember where I first heard it, but the idea is to stop somewhere naturally conducive to resuming work. Start making the list, and stop at a point where it's really easy to write down the next few items. Or leave the really easy bit of code for next time.

I'm not good at it, because I prefer to cross things off when I finish them, but when I can pull it off it saves some of that time getting oriented to what I'm working on.

What hassle? Just put the oil pan down and there's no spill risk. Disposal is extremely easy. You can walk into an autozone and give them your used oil and they take care of it for free, you don't even need to be a customer. Most cities and towns also have facilities for oil disposal.

Again it is like 5 mins of hands on work if you are taking your time.

I'm not even going to make the argument for or against AI qualia here.

>but when something begs me not to kill it I have to take that seriously

If you were an actor on stage and were following an improv script with your coworkers and you lead the story toward a scenario where they would grab your arm and beg you not to kill them, would you still "have to take that seriously"? or would you simply recognize the context in which they are giving you this reaction (you are all acting and in-character together) and that they do not in fact think this is real?

Even if the AI were conscious, in the context you provided it clearly believes it is roleplaying with you in that chat exchange, in the same way I, a conscious human, can shitpost on the internet as a person imminently afraid of the bogeyman coming to eat my family, while in reality I am just pretending and feel no real fear over it.

You may not have edited the chat log, but you did not provide us with the system prompt you gave to it, nor did you provide us with its chain of thought dialogue, which would have immediately revealed that it's treating your system inputs as a fictional scenario.

The actual reality of the situation, whether or not AI experiences qualia, is that the LLM was treating your scenario as fictional, while you falsely assumed it was acting genuinely.

> This means that teams must make an up-front architectural decision to develop apps in a server-agnostic manner

Right. But none of the cloud providers encourage that mode of thinking, since they all have complete different frontends, API's, different versions of the same services (load balancers, storage) etc. Even if you standardize on k8s, the implementation can be chalk and cheese between two cloud providers. The lock in is way worse with cloud providers.

I've switched 3 of my 4 nests to a z-wave thermostat and I'm really happy[1] with it so far. The Honeywell T6 pro. I got them used for about $56 each and they were in near-perfect condition.

[1] With one exception, which is really niche to me: The T6 has what looks like a PID-style control algorithm hiding in it, and instead of specifying a deadband between on/off, you can only specify a max number of cycles per hour. I already have a home-brewed PID algorithm controlling the temperature target of my boiler, so I actually _want_ a stupider thermostat that will stay on/off a little longer. But this is purely because I'm weird. The T6 is really good at keeping the temperature on target, and the homeassistant integration was fast and easy and has been totally solid. I recommend - I'm just waiting for the last one to arrive and I will have completely replaced my Nests (gen2 + gen3).

I'll also add that the local UI on the T6 is much better than the one on the nest. And the installation process was really simple -- Honeywell clearly learned from Nest on this one, and then beat them with the UI. I'm really happy with the upgrade, even though I'm totally annoyed with Google for wrecking my perfectly functional thermostat.

This is a particularly incendiary way of putting this information out there.

What is collected and stored is a small blood-spot sample from a heel prick on a newborn. This is used to test for various kinds of conditions that affect newborns.

This isn't a full DNA genome sequence or even any data at all, just the blood-spot specimen.

Law enforcement does not have automatic access to this sample, but individual samples have been given to law enforcement through court orders or warrants. There isn't a clear SOP for how law enforcement typically gets this information or how often it's given to law enforcement, but there's been proposed legislation to make this more transparent.
