Shipping from China to a US coastal warehouse is probably modestly under $200, including packaging, assuming it's shipped in a 40" container. Possibly less if there's other cargo that can be used to fill the remaining space.

I suspect the domestic costs are really dependent on volume (like, can you ship a container of 45 TVs to a warehouse near NYC or do you have to ship each unit individually) and I don't feel confident estimating that side of it.

I ended up doing something similar to this project a year or so ago: for nearly an entire year, I tracked every single thing I ate or drank.

Who knows how many hours I spent scanning nutritional facts on the backs of boxes, estimating amounts of liquids, and even tracking sips of water. And weighing myself! Thank goodness I used a "smart" scale at least, and I didn't have to worry about carefully inputting my weight to an app each time.

But the whole project was an exercise in perfectionism. "I have to remember this sandwich and log it the next time I'm alone" made me anxious, but once I logged it, I felt a sense of completion. The database and my personal history are now at nirvana. Everything is complete.

All for me to learn things every human alive knows today: eat more food and you'll gain weight; eat less food and you'll lose weight. Yes, I can now tell you the exact average difference in calories I'll eat, statistically speaking, on a day that I have adderall in the morning vs a day that I don't. Yes, there's a similar (but much smaller) difference in average calories per day if I have caffeine in the morning as well. And I can tell you that I generally eat an additional 200-400 calories per day on a Fri-Sun than on a Mon-Thu. Wow, groundbreaking.

I've always had a lot of water, but matching foodanddrink.csv to my HealthKit data showed that I have more water on days that I walk more steps. Mildly interesting to see it written out for me? I guess. But was it worth cataloguing every cup of water? Absolutely not.

Was any of [gestures broadly at me pulling out my phone and cataloguing each item I ate] necessary to learn that? Of course not. It gave me a chance to look back at the database and say "Wowee! I did that! Every day for a year, wow, I'm so cool!" and not much else.
Show HN: Find Engineering Manager Jobs Efficiently
by oah | 2026-03-10 14:34:52+00:00
I built a site to find engineering manager jobs and make the manager job search less painful. This was created out of my own job search last year. I was using various job aggregator sites and spreadsheets and wanted a more efficient method.

The main value of the site is:
* High-quality job listings and data that is updated daily. It saves countless hours not having to sift through irrelevant or stale job listings.

Give it a try and feel open to share any feedback.

Consumers just keep putting up with it. TVs are not a necessity; it's not like electric bills or healthcare. There are more ways to consume content than ever before, and more content available than ever before. Not owning a TV in the 80s or 90s was something of a big deal. Now, it couldn't matter less. But people are still putting up with whatever crap manufacturers are putting out. It should be easy to vote with wallet (even that means simply not purchasing a TV) but consumers just keep buying this crap.

> however retrospectively, it did not justify the hundreds of hours I invested in this project.

Trying to extrapolate this conclusion to the entire "quantified self" movement is not correct. The issue is the time cost, not the act itself. If a trusted company came along (as if...) that sucked up this much data to allow you to answer these questions with minimal effort, I'm sure this would be a different story.

Anything at the fringes of tech with no tried and true solution requires hundreds of hours of effort. The author's conclusions are also personal, there are other styles of living and conclusions to be drawn that change the calculus on whether to do it or not.

You're downplaying it in the same way that others are overplaying it.

- There are servers that are labelled adult only because it's simpler to label _everything_ as causing cancer than it is to only label the correct things. I can't join channels for some games because they're "adult"; even though they're not

- There are servers that are getting rid of content because they don't want some automatic system to label them as adult, even though they're not. There's a game server that got rid of it's meme channel, because people could (but don't) post content that some system might see as adult.

So it is a bigger deal than you're making it out to be. It's negatively impacting people and servers that have no interest in having anything adult on them.

We weren't talking about COGS, we were talking about "cost of compute", which isn't an accounting term.

For the rest, anyone can define and apply an accounting metric but that doesn't mean it tells you anything useful. If you look at the unit cost of any typical IP business it's nearly zero. Yet, many companies lose money on making movies, video games, apps and books.

Grok was the best every now and then but they committed the capital crime of trying to charge 50% more than the competitors who were only 20% or so worse.

There's kind of this weird thing in Silicon Valley where CEOs and investors keep telling people to raise prices! The definition of a moat is you can raise prices!!!

But these folks usually don't have the experience of being broke or saving for retirement and such. They don't understand that an extra $10/month is a heck lot of money. And so nobody really wants to try it and it has a dampening effect on the virality.

It actually went down, unless you are with a scam-company or had a time-limited offer run out.

Everyone who cares is seeing it. You have to change your contract, that's how the market works. Too many people seem to not understand this aspect.

No, it's just your typical distorted market. This happens in places that do net metering, where each joule you send to the grid pays for one joule drawn from the grid. This effectively vastly over-pays for local production, because it doesn't account for the costs of maintaining generating capacity or transmission. Those costs then have to be borne by the other customers instead. Utilities wouldn't offer this voluntarily. Where it exists, it's because it's legally mandated as a way of driving adoption of home solar.

The economically sensible way to do it is to pay individual produces for their power at the same rates they'd get if they were a "real" provider. This would be substantially less, so you'd have to provide much more than one joule to the grid to offset each joule consumed from it. With this, someone feeding their home solar power into the grid is still paying their share for transmission and generation, and there's no undue burden on other customers.

My default reaction to the introduction of any age-verification for any service is the closing account. Goodbye Discord, account closed out of protest.

The second option is ignoring the verification request. Goodbye online-gaming-with-strangers on Xbox. (I see this as a positive). Same goes for Ubisoft who aggressively wanted my secret papers to verify my identity.

I've yet to come across anything I want or need outside banking or government use where age verification benefits me, or is so useful/important that I would willingly hand over critical secret documents. I've not even needed to use a VPN for anything. It doesn't mean it won't happen, but when it does, option #1 or #2 is going to cover everything.

Which circles back to the main point here - if I ignore it, then effectively I get identified as a non-adult. How does this protect anybody?

Even without a pressure cooker, you can cook beans faster in a microwave oven.

However, you still need more than a half of hour if you want the beans to be soft, e.g. 45 minutes (after having soaked the beans for a half of day).

I cook all my food in a microwave oven. Except for beans, I have never encountered any vegetable that would need more than 15 minutes. For lentils or chickpeas, around 12 minutes is normally sufficient.

Wasn't there some recent argument that world models won't achieve AGI either due to overlooking the normative framework, fundamental symmetries of the world purely from data and collapse in multi-step reasoning? JEPA is sacrificing fidelity for abstract representation yet how does that help in the real world where fidelity is the most important point? It's like relying on differential equations yet soon finding out they only cover minuscule amount of real world problems and almost all interesting problems are unsolvable by them.

TLDR: There are a bunch of beautiful, new, empty office biotech labs buildings in Boston. Buildings made to be labs are constructed completely differently than buildings meant to house people (mainly around air and water flow). Therefore turning those labs into anything other than labs (eg housing) will be really, really expensive.

That's the low quality comments that ruin everything.

China connected 4 solar panels per SECOND last year. China is also has 265x the population and has growing energy demands. They build much less coal than they phase out.

All you can muster is a "But uh china is doing something so you are irrelevant" which is neither helpful nor correct. You are supporting the status quo and support not changing a damn thing.

So, I have been thinking about this for a little while. Image a model f that takes a world x and makes a prediciton y. At a high-level, a traditional supervised model is trained like this

f(x)=y' => loss(y',y) => how good was my prediction? Train f through backprop with that error.

While a model trained with reinforcement learning is more similar to this. Where m(y) is the resulting world state of taking an action y the model predicted.

f(x)=y' => m(y')=z => reward(z) => how good was the state I was in based on my actions? Train f with an algorithm like REINFORCE with the reward, as the world m is a non-differentiable black-box.

While a group of neurons is more like predicting what is the resulting word state of taking my action, g(x,y), and trying to learn by both tuning g and the action taken f(x).

f(x)=y' => m(y')=z => g(x,y)=z' => loss(z,z') => how predictable was the results of my actions? Train g normally with backprop, and train f with an algorithm like REINFORCE with negative surprise as a reward.

After talking with GPT5.2 for a little while, it seems like Curiosity-driven Exploration by Self-supervised Prediction[1] might be an architecture similar to the one I described for neurons? But with the twist that f is rewarded by making the prediction error bigger (not smaller!) as a proxy of "curiosity".

Well, in 2019 an estimated 840 people died in the U.S.A. by red light running (<https://ncsrsafety.org/stop-on-red/red-light-running-fatalit...>). That's about 2.3 people a day, so last person killed by someone running a red light was statistically about 10.5 hours ago, the last one before that about 21 hours ago.

Someone explain how you'd create a vector embedding using homomorphically encrypted data, without decrypting it. Seems like a catch 22. You don't get to know the semantic meaning, but need the semantic meaning to position it in high dimensional space. I guess the point I'm making is that sure, you can sell compute for FHE, but you quickly run up against a hard limit on any value added SaaS you can provide the customer. This feels like a solution that's being shoehorned in because cloud providers really really really want to have a customer use their data center, when in truth the best solution would be a secure facility for the customer so that applications can actually understand the data they're working with.

I'll admit the connection is loose, personally found it amusing because:

Mike is the archetypal nihilist (Sociopath), the other two would potentially be engaging in a Clueless interaction if Mike wasn't there, according to the Scott/Rao theory of jokes, you need 3 for a Loser joke.

The preceding banter seems to be more of a Loser Gametalk: no social status is at stake; it's irrelevant to their white-collar role. Mike's intervention is typical of a sociopath; the wall breaking joke is that these Losers don't know what his real job is. If they did, the pointless but playful debate would have died right there-- because it'd get too real

If these were Clueless middle managers debating their value to their company, it might even be out of character for Mike to notice them..

Cool demo. The tricky bit with browser workflow agents is figuring out which workflows to automate in the first place. Most people don't even realize they're doing the same thing over and over - they just do it.

I've been building MemoryLane (https://github.com/deusXmachina-dev/memorylane) which comes at this from the other side - it records screen activity, spots repeated patterns with AI, and then tells you "hey you keep doing this, want to automate it?" Works as an MCP plugin for Claude/Cursor.

Feels like pattern detection (finding what to automate) + browser agents like yours (actually doing the automation) is the right combo. Are you thinking about the discovery side at all, or mostly focused on execution?

I still won't use what? I use Opus now, and I will use Opus then too, but as I clearly stated:

My default model has now dropped to Sonnet, because Sonnet can now do most of my tasks, and we already use Kimi, Deepseek, and Qwen.

They're just not cost-effective enough to be my main driver yet. They are however cheap enough that for things where the Claude TOS does not let me use my subscription, they still add substantial value. Just not nearly as much as I'd like.

The bulk of my tasks won't get harder as time passes, and so will move down the value chain as the cheaper models get better.

For the small proportion of my tasks that benefits from a smarter model, I will use the smartest model I can afford.

> I consider myself a better than average programmer and I have no problem admitting that using Claude Code has dramatically improved the quality and speed of my output.

Genuine question but is it really your output anymore?

There are projects where the output is all what matters for example (Some script/basic project-prototyping/idea-validation) and then there are outputs where you want to feel the ownership "my code, my software"

AI has definitely tainted the latter and depressed people into not releasing source code anymore because they feel like AI will just train on it/ AI issues and even read the Sam and matplotlib on that whole controversy. So in my opinion, AI has definitely tainted some pretty valuable priceless things.

The best use I got from my Apple Watch was to use the companion app of my gym routine tracker (to track current loads and personal best) and play music so I didn't have to bring the phone to the gym.

That was it, I got extremely annoyed by notifications so over time just disabled them. Also for some reason the heart rate monitor glitched a couple times, got alerts about my BPM at 180+ while I was sitting on the couch.

Eventually I just stopped using it and now sits in some drawer.

>The problem is that 30-50% of voters would just look at that and say: Why are you spending €250B on corporate subsidies instead of giving us €250B?!

Why is it a "problem" for voters (aka the taxpayers) to ask such questions to their leaders to justify on how their tax money is being spent? To me this feels like basic transparency that keeps democracy in check.

To me it's the problem if politicians don't have or don't want to answer those questions because then, either they're grifting or they're incompetent.

It's not like we don't have a laundry list of mismanagement, couch corruption cough, of governments spending money on bullshit with nothing to show for, while stuff healthcare keeps being underfunded.

So yeah, if you spend my money, you better have an answer.

I'm building SnowSignals - the personal ski guide. We help skiers make the most of their day on the mountain no matter the conditions, combining weather, snow conditions, and resort information to create tailored plans.

To accomplish this, I built a snow metamorphosis model that forecasts what the snow surface skis like, a dataset of resort "topography", and an optimizer that gives skiers an idea of how to best structure their day.

It's not just the unions wanting to keep ICEs which are far from dated plus absolutely necessary to keep and further develop.

A monolithic EV-only approach simply isn't feasible since not everyone can switch to an EV - above all, the current state of charging infrastructure is lightyears behind.

Ditching ICEs is the worst thing that could happen. It's really just common sense that happens to be unpopular.

We recently looked into an interesting controversy around the Python library chardet that touches a broader question in open source.

The situation involves an AI-assisted rewrite, a move toward MIT relicensing, and concerns about how this relates to the original LGPL codebase. Historically, similar situations were handled through clean-room reimplementation, where a new implementation is written without copying the original code.

AI tools make this boundary less clear. Modern models are trained on large collections of public code, including open-source repositories. When developers use these tools to help rewrite a project, it raises questions about whether the result can really be considered independent from the original work.

The chardet case is interesting not only because of the library itself, but because it may signal a broader issue for open-source governance: how licensing and attribution work in an era where AI-assisted rewrites become common.

You don't really get a lot of options anymore. When people around don't really care and just buy this junk because it's cheap, and they "need" a new TV ever three to four years, for some reason, then you get priced out of the market pretty quickly. Even if you look for TV, and yes I want a TV, not a monitor, without all this junk, there's not really any options available locally anymore. I believe my only option is the Thompson Easy TV, which is great, if I needed a 43" TV or lower.

Apparently I can attempt to import one from Romania, but that seems fairly complicated. Even sites that recommend dumb TVs just recommend SmartTVs that works well as a dumb TV.

I love the BSDs; I have the most experience with FreeBSD, I regularly use macOS, and lately I’ve been learning NetBSD due to its rumpkernel.

With that said, with the decline of commercial Unix and the dominance of Linux, POSIX, in my opinion, has become less important, and in its place Linux seems to be the standard. I prefer the BSDs to Linux due to its design and documentation, but Linux has better hardware support, and the FOSS ecosystem, especially the desktop, is increasingly embracing Linuxisms such as Wayland and systemd. The FOSS BSD ecosystems are too small to counter the Linuxization of the Unix ecosystem, and I feel that Apple does not pay much attention to the BSD side of macOS these days.

I don’t expect the BSDs to die, but I do believe they’ll need to find ways to adapt to an increasingly Linux-dominated FOSS ecosystem.

I took a brief skim through TFA so apologies if I missed that it was mentioned, but wanted to bring up the Embedded Template Library[0]. The (over)simplified concept is: it provides a statically-allocated subset (but large subset) of the C++ standard library for use in embedded systems. I used it recently in a C++ embedded project for statically-allocated container/list types, and for parsing strings, and the experience was nice.

What is the value of the EU if's it not coordinating multi-national scale efforts?

This would need to be a joint venture as some places are really good for wind, and some places are really good for solar, but not every country on their own has access to those locations. The budget for the EU doesn't matter, because this project would be a separate line item with it's own funding.

Energy independence is extremely valuable. Way way way more valuable then $250B or even $500 or $750B for that matter. Society runs on energy, and if it's not fully yours, you are always a rug pull away from social collapse.

If 2022 was a cold winter, and America had a cold leader, this project probably would have breezed through the bureaucracy in a week.

Hex math is weird. Since there are 6 directions instead of 4, there's no simple mapping between hex positions and 2D x,y coordinates.

There is, a hexagonal grid is isomorphic to a [skewed] rectangular grid, i.e. it can also be indexed with a coordinate pair (u, v). The neighbours are at offsets (+1, 0), (-1, 0), (0, +1), and (0, -1) - just as in a rectangular grid - and the two additional neighbours are at (+1, -1) and (-1, +1). The coordinates in the plane are (x, y) = (√3(u + v/2), 3v/2) or some variation of this, depending on how exactly one lays out the hexagons and picks axes.

It is surprisingly hard to find a good illustration for this, or maybe I am using the wrong search terms, but here [1] is the best one I could quickly find.

Also, it is your digital identity, there is no substitute.
