Refresh cadence has little to do with sustainability.

Consider cars: manufactures come out with new ones each year with marginally differences. Is that somehow unsustainable and they should instead keep manufacturing an old design for years? Does that mean once the 2026 model starts manufactuing you go dump your 2025?

It makes more sense to iteratively improve your design and stop manufacturing old things if you can manufacture something better.

The real sustainability argument is about support length (which apple does well), and repairability (which apples does ). Changing to a 3 hear cycle is orthogonal to both of these.

One of my first jobs was working for my university while attending. We had a small student lead team of people that did IT work for other students, and faculty. We'd fix or at least attempt to fix any software issue or hardware issue that we feasibly could with the tools we had available.

In my unsolicited advice, I recommend your son take both devices. I'll spare you my countless war stories, but I can confidently say I have seen many students up a creek without a paddle at some of the most unfortunate times.

The whole point is that it isn't. Liquidity availability is big part of finance.

In your specific example of other side - yes - just because someone who needs to sell a chunk for reasons like an emergency, retirement or consumption needs doesn't mean they are happy to sell the rest of the chunks at that price.

Market based valuations only work in case of very high liquidity publicly traded assets and only if you don't own a significant %.

This makes your argument weaker, not stronger though. If there isn't liquidity market based valuation doesn't work.

>>This has been a fact for hundreds of thousands of years by now.

It isn't and never was. Liquidity was always big part of it.

Some absolutely stunning shots here, wow! Photos like this inspire me. The compositions with the huge moon rising behind the landscape are particularly impressive. You need a huge lens to get that kind of perspective, and atmospheric effects and camera shake become more pronounced. The other photos of the night sky impress me less honestly because they are almost always composited (i.e. the Milky Way doesn't actually look like that).

>>> People are starving to death and the world's brightest engineers are ...

>> This is a political will, empathy, and leadership problem. Not an engineering problem.

> Those problems might be more tractable if all of our best and brightest were working on them.

The ability to produce enough food for those in need already exists, so that problem is theoretically solved. Granted, logistics engineering[0] is a real thing and would benefit from "our best and brightest."

What is lacking most recently, based on empirical observation, is a commitment to benefiting those in need without expectation of remuneration. Or, in other words, empathetic acts of kindness.

Which is a "people problem" (a.k.a. the trio I previously identified).

I agree, but you're never going to get an LLM to be perfect, especially when it was trained to behave differently. Eg i mentioned it had, maybe, a 70% success rate for linting and formatting. However it had maybe a 50% success rate at not using emojis. For some reason, claude loves to use emojis in its output.

That isn't the point though. The parent asked if claude code had something similar to the system prompt they mentioned. It does, it's memory. Actually i believe it has that and a system prompt heh.

But yea, aside from that you're never going to get perfection from an LLM. Don't even try, imo. Use deterministic wrappers where possible. Eg i don't have an emoji problem anymore, Claude never prints emojis now. Why? Because i use a hook which prevents it from writing emojis.

I had an ad on Facebook marketplace for a synthesizer. The guy who bought it gave me his business card - cloud architect for a competitor. He didn't give it to me because we were in similar field - we had a pleasant conversation over shareEd hobby and he gave it to me then, after which I realized we were in same field, so clearly he gave them around a lot.

If I consider changing jobs, or if I need those very particular services he's getting a call :-).

Speaking of charging setups: I have a wide selection of battery-powered tools all running the same standard of battery (Ryobi, but that's but immigrant, the other manufacturers have the same products). Week, actually, it's two, one for the big machines like the lawnmower and chainsaw, and one for the small ones like the drill. But one of the items is a battery dock using the big battery, a 4 amp-hr li-ion brick. It offers a standard mains socket (as well as USB-A and USB-C sockets) in which I plug my laptop when I work from home on my front porch or a smart-speaker when we want music outside.

For my laptop, one battery adds at least 80% to my battery time, plus I don't get down-throttled for being in battery power only, giving me about 4 hours at full power and another 5 on regular battery thereafter, plus the batteries are hot-swappable.

You can buy external battery backups specifically intended for electronic devices for significantly more money and they only give you one charge.

I think it's an canary in a coal mine, and the true writing is already on the wall. People that are using AI like in the post above us are likely not stupid people. I think those people truly want love and connection in their lives, and for some reason or another, they are unable to obtain such.

I have the utmost confidence that things are only going to get worse from here. The world is becoming more isolated and individualistic as time progresses.

Not OP but there are many methods, with more available as you gain more execution privileges. On the “no privileges” end, you have things like accept-language and ping times (which can be coupled with known location of exit node to get an extremely rough “ping to exit” time.. not very useful but at least another data point). Then you have linkage to other devices, e.g. same account logs into site with and without VPN. Or if you have any inputs from the user (search history), maybe they make some typos or Autocorrect that leaks metadata about their native language. On the “some privileges” point of the spectrum, if you’ve got JavaScript execution, you can learn a _lot_ about the region of the user. And on the “many privileges” side, where you’ve got native code execution in a mobile app or similar, it’s game over.

For literature on this kind of thing, look into “PETS” (privacy enhancing technology) research. Incidentally, Tor spends a lot of time plugging these holes in their browser…

wow, interesting, and thanks for the feedback.

android 13 here.

I am not sure what the reason is, then.

I'm surprised it's still being offered period! My parents live in a remote area outside of a rural town in one of the USA's smaller states, and even they haven't had dial-up in ~15 years. We grew up with dial-up until about 2010, when they switched over to (absolutely terrible) satellite internet. HughsNet, I think it was called. Two-ish years ago they switched over to Starlink and it's been working well (when it does work, anyway).

I have what I call my “Victorian Calling Cards.” I’m retired, and have no need to advertise or boast.

They are fairly fancy moo.com cards, with my name, email, and cellphone. Nothing else.

On the back, is a fancy “dragon head” logo (the one you see, if you look at most of my social media accounts). It’s actually my old artist signature. It’s over a burnt umber gradient.

People like them, and use them.

It’s unfortunate that this CEO helped China’s investments and ambitions. But he’s not the only one. Warren Buffett helped BYD at an early stage, and now they threaten the entire American and European car industry. Nike used slave labor in Xinjiang, a region that shouldn’t rightfully even be a part of China (like Tibet). Amazon is basically a flea market that gives Chinese brands a path to American customers in place of American brands.

There are many more. That said, given his role in the Cadence China scandal, his other actions and interests in China are extra suspicious.

That's the thing, the brightness is actually only 350nits on Dell, but 400nits on HP and Philips I've linked; the original MSRP was the same as the Dell, it's only the sale price that ended up being really good on those. So, the only TB monitor in its class actually has worse brightness than many of the non-TB options.

The HP is calibrated and has amazing colours, and it's 90Hz, too, although I keep it at 60Hz.

The Philips monitor is 4k UHD and also IPS Black, same 2000:1 contrast as all IPS Black panels share, so, I'm not sure why you'd get the Dell with the lower resolution and lower brightness at a higher price. The only true benefit of Dell is 2.5GigE and 120Hz, but 350nits is actually a downside compared to 400nits of the cheaper monitors I've listed.

BTW, you've never addressed the UPS issue.

Do any docks at all work when the power is out? How do you take that into account when you need to connect stuff like SSD, kb and mouse? Do you suffer data loss on your SSD because your laptop lacks standard ports and dock use is required that can't be powered by the laptop anymore? Or do you get UPS for your laptop just for the dock? I just don't understand how the dock requirement is not a big deal. I got a laptop simply because it's fanless and has an integrated UPS, I didn't need it to be portable otherwise.

I have built something similar but the opposite of the concept, instead of turning one massive computer into a virtual IoT testing lab that simulates hundreds of smart devices, it was creating a unified single ‘entity’ that uses dozens of embedded devices (SBC) resources while offloading processes on demands when possible but sharing knowledge as well, it was useful on a swarm drones platform since one thing processed in any will be shared among others, so say if one avoided an object, that knowledge will be shared among the other ones. It was PoC, how useful it’s in real situations that’s do be determined later.

Could be! Depends if MS starts putting some more money behind it, including marketing. They're pretty deep in an AI-everything spiral right now though.

I'm a Clojure guy, but the ML family (specifically OCaml and F#) have always interested me as another branch of functional programming. I started out in the before times as a .NET Programmer (VB6 -> VB.NET -> C#) and have toyed with F# a little since then. It's cool, but the tooling leaves a lot to be desired compared to what's available for OCaml unless you decide to use full fat Visual Studio.

What I particularly like about them is the middle ground of inferred types. I don't need types since maps, lists, and value types are enough for me in almost all cases, but if I must use a strongly typed system why not let the compiler figure it out for me? I always thought that was a neat idea.

Afraid not. The documentation for AllowSetForegroundWindow() and the associated mechanism still exists, of course:

https://learn.microsoft.com/en-us/windows/win32/api/winuser/...

But the last time I tried to test code using this to properly hand off foreground permission from one process to another, I had a hard time testing it because I couldn't get it to fail. When this mechanism was first introduced in Windows 98 and 2000, it was pretty aggressive -- if you were past the input timeout and foreground permission hadn't been forwarded or already shared, the target application would fail to come to the front and its taskbar button would light up instead. I haven't seen this happen in a long time on current Windows, programs steal focus all the time.

Are you happy with their compromise to bring it back for plus users? I spend so much time evaluating models for work I felt bad seeing my favorite o3 missing from the app this morning. I still have it via the API wired into projects. But in the app it was the first reasoning model I worked with constantly, learned a lot and genuinely brought about a sense of wonder. When I’m old and gray and someone mentions o3 I can say it was a major part of this time in my life.

I tried F# when we were building out a scraper at a startup. After a bit, I realized that must of the things could also be done in C# and ended up using C# instead because it's just a bit more accessible. F# looks neat, but C# has a lot of parity at this point on some of the core selling points IMO.

Something definitely makes me uneasy about it taking the place of interpersonal connection. But I also think the hardcore backlash involves an over correction that's dismissive of llm's actual language capabilities.

Sycophantic agreement (which I would argue is still palpably and excessively present) undermines its credibility as a source of independent judgment. But at a minimum it's capable of being a sounding board echoing your sentiments back to you with a degree of conceptual understanding that should not be lightly dismissed.

The final section pounding the desk about how terrible ending the program was seems like it is oddly at variance with all the evidence OP had just laid out about how the program wasn't working well anymore and so wasn't actually financially a good idea. It's weird to quote a bunch of things like studies showing that 'internal R&D spending works worse than external for ROI' and then write a big moralizing sermonizing conclusion about how ending internal R&D is bad for profits and how terrible it is there's no 'patient capital' (capital which was plenty available before - what's the theory, investors stopped liking making money? insurance companies with century-long investment horizons ceased to exist? etc).

I am not confident most, if any of them, are even real.

If they are real, then what kind of help there could be for something like this? Perhaps, community? But sadly, we've basically all but destroyed those. Pills likely won't treat this, and I cannot imagine trying to convince someone to go to therapy for a worse and more expensive version of what ChatGPT already provides them.

It's truly frightening stuff.
by selfhosttoday | 2025-08-09 02:20:28+00:00
self hosting is obviously a spectrum - with building a physical building for space, getting power, equipment, techs, etc on one end, and something like Google Cloud Run or DynamoDB on the other, but...

I don't see why it's that hard these days. is it really so unreliable to go on something like Hetzner, install Ubuntu, Docker Swarm, and a clustered database like TiDB or CockroachDB both of which support functionality to make it easy to schedule backups to something like s3, or other hosts, or ftp, etc.

Even if you have updates, do it one machine at a time, swarm by default is load balancing your traffic, and you're using a clustered DB so it shouldn't be a problem.

and of course, put it all behind cloud flare, because why not.

I get how like in 2012 it was annoying. you had to use Postgres, which is a great database, but then you had to deal with backups and k8s and swarm barely existed, so you had to roll your own nginx or apache config for load balancing and was annoying. in 2025 seems crazy to not do it. going to the article, obviously you should as a sass support it, if my premise is accepted =)

and before someone talks about security - it's also very easy to set up service accounts or iam improperly and leave your rds, firebase, whatever thing totally open or on defaults...

>>- look at the medical plans that are on offer in India.

The one's that companies offer are quite good, actually.

I'd have depleted my life savings, and gone bankrupt several times around COVID years with my parents health, if I didn't have company health insurance.

Good for me, because I knew people in hospital sitting in the waiting lobby literally crying because they were done financially. Like finished for life.

Having said, this in India the market for this things is still building up, and given how big India is it will take years before it reaches the US stage of profit seeking.

Indeed. I read a great write up by Sam Cox of Tracebit[0] on his selection of C# and his focus on productivity nails it on the head. One of the best ORMs, rich standard libraries and first party packages, and has been converging with TypeScript and JavaScript over the last decade[1] while having all of the advantages of runtime type safety.

Folks that last looked at C# over a decade ago don't know what they are missing.

Yes, remote start breaks the model… which is why drive off release and remote start are separate systems. On modern European cars with automatic transmissions, the TCU will not release Park until the immobilizer (short range, challenge response) is released, and generally the ECU also limits torque request and vehicle speed.

> This is also how a lot of vehicles are stollen, because of abuse/misuse of CANBUS

On vehicles with poor cryptography architecture (Honda!), yes. On most other vehicles, no, because the immobilizer messages are cryptographically authenticated, usually by using an AES MAC where the key must encrypt random bytes transmitted by the immobilizer master using a shared AES key, and all participating immobilizer modules use a similar system to verify that every module shares the same secret material. Now of course if this secret material can be extracted the system breaks (see XHorse, Abrites, etc.) but this usually requires invasive and time consuming attacks far beyond the headlight thing (for example, removing and physically opening a control unit to use an exploit to dump its key material).

A quick check on GPT suggests that shipping the thing via ocean freight is going to be comfortably less than 1% of the carbon emissions of manufacturing. Batteries are really tiny, so they ship well, and they are really complex, so they are more difficult to manufacture than say a simple plastic toy.

I'm glad you are making use of your li-ion batteries, I'd love to see aggregate data on that. I know in my own personal life, rechargeable AA batteries usually get lost or forgotten before their third recharge for me. Climate wise, I'm probably net negative overall on my rechargeables.

But it's also kinda not the right thing to focus on for climate. Driving 50 miles in a gas car will cause a greater climate delta than manufacturing a battery. Eating 12 ounces of beef (300g) causes more emissions than manufacturing and shipping a battery. One international flight can be equivalent to several hundred batteries, etc

At my previous employer, we used Redis for publicly-documented rate limits, but we applied them after our rate limiting infrastructure already evaluated defensive infrastructure-oriented rate limits.

We generally found that this worked out fine. Customer-facing limits were numbers measured in hours or days; infra limits were measured in seconds or minutes.

Certainly you wouldn’t want to rely on a central db for infra-oriented rate limiting, in any case.
Show HN: Imgenhancer.ai – AI tool to upscale, transform, and generate images
by longshu | 2025-08-09 02:25:56+00:00
Hi HN,

I built ImgEnhancer.ai, an AI-powered tool that lets you: - Upscale low-resolution images with high clarity - Transform styles and aesthetics with filters - Generate brand-new visuals from text prompts

I created this because I found existing tools either too slow, low-quality, or complicated for everyday creators. My goal was to make something fast, intuitive, and—hopefully—magical to use.

It’s free to try right now. I’d love feedback from this community on: 1. Image quality vs. similar tools 2. Ideas for features that could be valuable 3. Any edge cases or limitations you think are worth testing

Demo: https://imgenhancer.ai/
