> If allocated to caffeinated coffee consumption, patients were encouraged to drink at least 1 cup of caffeinated coffee (or at least 1 espresso shot) and other caffeine-containing products every day as per their usual lifestyle

I tried to skim to figure out how much caffeine/ml was actually in the drinks, but seems the researchers don't know themselves either? Wouldn't there be a huge difference depending on the beans, how it's made and so on? 1 espresso can be made very strong with packed coffee, or it can be made very weak, "1 cup of caffeinated coffee" basically says nothing at all, unless I'm missing the true definition elsewhere in the paper.

This is all nonsense and you are just falling for marketing that you want to be true.

The whole space is largely marketing at this point, intentionally conflating all these philosophical terms because we don't want to face the ugly reality that LLMs are a dead end to "AGI".

Not to mention, it is not on those who don't believe in Santa Clause to prove that Santa Clause doesn't exist. It is on those who believe in Santa Clause to show how AGI can possibly emerge from next token prediction.

I would question if you even use the models much really because I thought this in 2023 but I just can't imagine how anyone who uses the models all the time can possibly think we are on the path to AGI with LLMs in 2025.

It is almost like the idea of a thinking being emerging from text was a dumb idea to start with.

It is worth noting that the US and Korea have already been very engaged in trying to work together on ship building, mostly for the US, which we seem to have gotten quite slow and costly at.

From the same source as this article, American HHI working with Korean HD HHI. No real action yet but both companies want to be working together. https://www.navalnews.com/naval-news/2025/10/hii-hosts-hd-hh...

That's also my opinion but I am ready to give them some excuse, because they have it harder than when it was just desktop computing.

Now we expect a desktop and a mobile app, also native and browser based. They all have different requirements. Even in the same category, such as iOS vs Android, some conventions are different. Having to write the app differently for each platform to make the best of it is not only expensive, but it may also be confusing to users who switch from one to another.

For example let's say you have a button on your desktop app that sees little use, but it is a nice feature for the few times it is needed. Because it is a desktop and you have lots of space and a precise pointing device, it stays. But for your mobile version, there is simply no room for it, so you remove it and tweak the workflow a bit so that it isn't needed anymore. Taken individually, they are both good decisions, but I can guarantee that the desktop user will complain that it is missing on the mobile app, and he would be right. It means you have to make a compromise you didn't have to make before.

I've been mulling over how to take ArchiveBox in this direction for years, but it's a really hard problem to tackle because of privacy. https://docs.sweeting.me/s/cookie-dilemma

Most content is going behind logins these days, and if you include the PII of the person doing the archiving in the archives then it's A. really easy for providers to block that account B. potentially dangerous to dox the person doing the archiving. The problem is removing PII from logged in sites is that it's not as simple as stripping some EXIF data, the html and JS is littered with secret tokens, usernames, user-specific notifications, etc. that would reveal the ID of the archivist and cant be removed without breaking page behavior on replay.

My latest progress is that it might be possible to anonymize logged in snapshots by using the intersection of two different logged-in snapshots, making them easier to share over a distributed system like Bittorrent or IPFS without doxxing the archivist.

The first personal computer generally available in the United States, the MITS Altair, grew out of projects like this.

MITS was an acronym: "Micro Instrumentation and Telemetry Systems". Ed Roberts and Forrest Mims made electronics kits for model rockets.

As a 1970s kid, I built Estes rockets, but I never did anything fancy. You'd spend a week or two of free time, building the kit and painting it. Then you'd blow it up on the launch pad, or launch it into the wild blue and never see it again. Or spend all your birthday money on a Star Wars X-Wing fighter, launch it, and have it nose-dive into the dirt about ten feet away.

Come to think of it, model rocketry was exactly like real rocketry.

Forrest Mims enriched my life in other ways, with his patient lab manuals for the Radio Shack electronics kits.
Show HN: GhanaHousePlanner – Construction planner and cost estimator
by ggap | 2025-11-15 20:27:02+00:00
Hi, I built Ghana House Planner https://ghanahouseplanner.com to help individual homeowners, builders, and DIYers in Ghana/Diaspora plan and estimate residential construction costs. The floor plans are built to comply with Ghana building codes.

It lets users:

- Select common house types (e.g., 2-bedroom traditional, luxury, etc)

- Customize materials (foundation, roofing, finishes, etc.) using up-to-date local pricing (updated monthly)

- See real-time cost breakdowns across categories (steel, electrical, plumbing…)

- Export or share estimates

- Manage different phases of construction

The rendering is built with React and is intentionally lightweight— the 3D viewer (currently under development).

The platform is free to use except for project management and using the LLM to define your house plans.

Current features include:

Region-aware material database (30+ items, sourced locally)

Modular cost estimator with category filters

Mobile-responsive UI (simple, fast, no bloat)

Next: job directory & marketplace (for local artisans & suppliers)

I would be happy to receive your feedback — especially on UX, scalability, or how tools like this could serve other regions. I believe this is also useful for Nigeria and potentially other tropical countries especially for the floorplans

> The reason it's interesting is that the subjects of these fake tests thought they might work and thus they skipped them.

This is just something you made up. Here's an alternative idea:

You are deciding whether to take a test. The test's results are 100% subjective. Anything you say during the test can be interpreted as a negative statement about yourself, and this determination will be made by the examiner.

Is taking this test a good idea? Why or why not?

Guns are trash on a plane. The use of a firearm is to be able to incapacitate someone from far enough away that they can't counterattack. Planes are densely packed with people. You'd have people surrounding and disarming you long before you could get control of the plane. How many shots do you expect to get off when anyone you're not currently aiming at can put their hands on the gun while someone else grabs your other arm to pull you in the opposite direction and a third person comes up behind you and kicks you between the legs?

Also notice that even if you somehow managed to kill everyone on the plane, you'd then be left with just a plane full of terrorists for the government to blow out of the sky. And if all you wanted was to kill a bunch of random people then being on a plane has nothing to do with it.

Another tell.

> If RoK wanted to spend a percentage of their GDP on enrichment facilities they could

And they have in the past. Guess who shut that down?

> They don't have an urgent reason to.

South korea is surrounded by 3 nuclear powers ( north korea, china, russia ) and militarily occupied by another nuclear power and yet, they have no urgent reason to? Good one.

> Why would RoK want their own enrichment facilities?

This is just absurd. Your questions answer themselves. And it's obvious you already know the answers but just are trying to distract.

You keep googling and I'll look for the citations. Okay buddy?

N=7

There is an entire industry built around clearing people, your tax dollars pay them. Of course everyone you listed was contacted, that’s the whole point.

How is filling out an SF-86 hard?

Maybe what you meant was, justifying the reason to get a clearance in the 90s was harder. Perhaps that is true. Getting a clearance isn’t hard.

The problem is that we also don't know how many lives it's saved. I'm serious! Someone I know was is crisis, and the thing that got her off the ledge in the middle of the night her wasn't calls to me going to voicemail, but her talking to ChatGPT. If we want to just rage against AI/robots/technology because we saw terminator and the robots are going to take our job, let's just admit that bias and not pretend this is a discussion, but in this real life trolley problem, yes people are dying but it's also saving lives because basically no one is rich enough to have their therapist on speed dial to call at 3am in a moment of crisis but ChatGPT is.

The impossible thing is that we can't know the numbers on the other side of the tracks, and even if we did, the trolley problem is a philosophical question without a solution because it's not a math equation with one right answer.

I never followed where things went after the contract was complete. Suffice it to say that we only cared about getting the protocol working, as the company was a contract engineering firm doing work for a product that was ultimately for military use. Actually testing it in the real world and improving behaviour was out of scope. We only tested it in a simulated network to make sure that the protocol correctly handled various cases (like certain wireless nodes not being able to see each other due to obstructions).

I had other friends back in the early 2000s working on WiMax, and the hardest part of their work was getting QoS right. More recently (still 10+ years ago), another friend implemented a TCP proxy for a major cell phone provider in the US that used a more wireless friendly congestion control protocol on the wireless network side of things as regular TCP breaks down when latency increases due to reception issues (which gets interpreted as congestion and triggers retransmits). Since the cellular base stations ensured that the wireless network was effectively lossless (albeit with periods of much higher latency), performance for end users increased substantially when the bulk of the TCP retransmits were suppressed.

There's a huge gap between making wireless work vs making it work well. For me, 5G is a step backwards as all the tricks used to push for higher data rates (like larger QAM constellations) make everything worse in rural areas with poor reception: there just isn't a good enough SNR 99% of the time for the new shiny, and the increased power usage does nothing other than drain my phone's battery faster than it did with older LTE. But that is where all the money for research is today.

Wireless is complicated.

We have always used apache as a reverse proxy and it has never been a problem from a performance point of view, performance issues has always been related to the database, business logic, network, disks and so on.

Using nginx might enhance a bit performance, but compared to other modules of the overall environment such performance gains are neglectable and unnoticeable for a normal user.

In our latest product I wanted to switch to nginx but I was surprised that for windows it is only in BETA version, and since our application MUST be deployable to both Windows and Linux environments we preferred a consistent software stack hence we stick on Apache.

The plan is to reconsider nginx once it officially supports windows, since no serious customer would accept a beta version for a production environment.

> Anything enabled by default without prompting in an update is usually against the user.

I believe that, of browser features released, the overwhelming majority are enabled by default (if they even can be disabled). Including TLS/https warnings, tabs, automatic page unloading, support for new HTML/JS capabilities, and so on.

Those don't generate an outcry--they're usually celebrated, in fact--so either browser updates are "usually" fine, or you have an extremely un-usual threshold for wanting things not to change.

> A J.P. Morgan report suggests that the AI industry needs to make $650 billion in annual revenue to deliver a 10% return on investments that companies are expected to make through 2030. The report, shared by analyst Max Weinbach on X, equates this to an extra monthly recurring payment of $34.72 from every iPhone user or $180 from every Netflix subscriber.

> To think we’ve handsomely paid our best and brightest the last few decades in pursuit of.. advertising?

I think "efficiency" is more accurate there. Even post-Google/ad-tech-boom the overall trends that started decades earlier continued to be: (1) faster turnaround time on communications, (2) faster delivery of result artifacts, (3) faster knowledge of changes in the market and faster response.

Advertising is a particularly visible field with lots of money to throw at those things (active investment trading is another). But practically every other industry has chased those same things as well, all the way down to things like parking meters.

Personally I'm not convinced that this is such a great thing anyway - does anyone enjoy their boss messaging you at 11PM on any day they want whenever they get the fancy? - but that's the larger reason so much brainpower has been invested into it.

TSA is security theater, but I think checks are still necessary. Otherwise people can bring C4 onto planes, blow themselves (and the plane) up in the air, and freak a lot of "Western civilization" out.

The liquids ban really is bullshit though, it's to prevent a fictional movie plot using a bomb mixed up using binary liquids...

In that case, you can still just use AWS Lightsail. It’s a simple service where you just spin up an EC2 and pay one price for VPC and an allotment of outbound data (inbound is free). You never have to worry about costs going out of control, VPCs, networking etc.

When you do need to graduate to real AWS, you can and your former Lightsale set up is treated like a VPC you can peer to.

I think this is a misunderstanding a lot of people have about clearance.

The different clearance levels are not really an indication of different levels of vetting being done to a person. If you can get cleared for Secret, there's no particular reason you couldn't get cleared for TS. It's the same SF-86 form, the same investigation (well, not that I know, exactly. All I know is that it didn't look any different from my perspective), the same interview. There are some differences in how often you'll get re-interviewed, I think. It's not really anything so onerous that you have to ever think about it, really.

The different levels are much more about need to know, which is driven by potential impact of breach. You don't even have to go through the lower levels before you get to the higher ones. The selectiveness of giving people higher clearance levels is more about controlling exposure surface area.

On top of that, clearance level is kind of more about what meetings you'll be allowed in, what conversations you'll be allowed to participate in. SCI is more having ongoing access to data. Then there are additionally "caveats", which are clearances to specific programs. Each of these things are a different axis in the clearance system, not different levels of a linear system.

Contrary to somewhat popular belief, a polygraph is not required to obtain TS/SCI. You can do a polygraph and that's a whole additional designation, "TS/SCI with Poly," as you might see in various job ads.

The fact that these people can't pass TS is extremely telling and extremely concerning. Not being able to pass basically means the investigation revealed information that the person has a reasonable chance of being coerced into providing information. A simple example: maybe you have a mistress you're trying to hide; a foreign intelligence service could try to blackmail you into providing them information. Maybe you have a lot of debt, especially gambling debt; you'd be judged particularly susceptible to taking bribes, which would also set you up to be easily blackmailed.

But I know at least one guy who is a raging pothead who has had high level clearance for the last 20 years. They didn't care because he was open about it. If he was open about it with them, then it was clear it wasn't an issue he could be coerced over. I know people who had past criminal charges on their records. They were fine, too, for the same reason. It used to be you couldn't hold a clearance if you were gay, but nowadays, people are much more open and accepting of it such that it's not a reasonable attack vector for coercion.

Basically, it means you've got major skeletons in your closet and probably tried to lie about them if you can't pass for S or TS. If you can't pass for TS then you probably shouldn't have a position of public trust at all, even for just handling CUI.

I'm really confused by your response.

Divulging where you've lived for the past 10+ years, having agents contacting your references, etc for "Secret" is not very onerous or difficult.

Given that, your subsequent statement that "Top Secret was notoriously more difficult in terms of paperwork" seems to be pointless.

I’d say don’t even think about this at all

Put all that questioning energy into asking yourself if your code is solving problems well and if there’s a way you can improve what you’ve built based on any issues you encounter along the way. Robust solutions exist for most problems, and when you find a problem in those and contribute or work around them, then you can say that you’re good.

Have your good friends look at your code, you can find great friendships in tech at work, or on X, discords/slacks. Share it in those spaces.

There we go again.

USA is the richest country in the world, people there, even the ones at the bottom of the work ladder, have access to riches that for most of the people on the planet are only dreams. You have no idea what it is to be poor or to live next to actual poverty (even I have no idea, and I live in a country that's poorer, and that when I was younger much poorer than the USA).

94% of adult Americans drive a car. Anyone there can go to a store that sells vegetables and raw meat, buy it, and prepare a proper meal that's cheaper than some deep-fried, frozen processed crap.

Enough with the performative virtue signaling. It's all so tiresome. Nobody in the USA goes hungry unless they really choose too at every single step in their lives.

This flies in the face of so many of my beliefs about Buffett and Berkshire, but obviously these are new days since he's now or soon will not be "the guy" in charge (at least technically-speaking).

Specifically, and these beliefs aren't based on an encyclopedic knowledge of Berkshire's investments, I think of Buffett as a value investor and obviously the market, and Google in particular, is now near its all-time high; he's eschewed tech except for Apple and that had more parallels to his investments in Coke ("everyone" drinks it (or used to) and "everyone" uses an iPhone); he doesn't tend to buy businesses he doesn't understand well (of course everyone knows Google for search, but just when there's an assault on traditional search he buys into the search company? So that means he thinks AI is/is going to be revolutionary, and he actually believes Google is destined to command a significant market share of whatever nebulous thing AI will be a decade from now?). Perplexing.

Watch this be the canary in the coal mine because Buffett passed the reigns and the new guy couldn't help but do something dumb day 1 with their boatloads of cash. Maybe it's not dumb of course! The stock is up materially since they likely invested so I guess I'm the dumb one.

James Hoffman did some interesting videos on that -- espresso is a more efficient extraction method than Aeropress, but less complete than a very high water to coffee ratio pour over for the same weight of ground coffee. Extraction of caffeine is very directly tied to contact time and temperature, so two double shots of espresso (40g coffee) can actually be less caffeine extracted than a single large pour over (25g coffee) when the pour over is upwards of 22% extraction (typical of 20:1 water to coffee ratios and modern zero-bypass brewers). Similarly, there are large differences in beans, so 22% extraction on weak caffeine beans might be way less than 18% extraction on much higher caffeine beans. This is most obvious in the fact that Robusta has much higher caffeine on average than Arabica. Also, 22% extraction has a lot more unpleasant bitter compounds, not just more caffeine, so it's not my preference for taste in general.

This is not accurate.

Polygraphs are not detecting lies, they're used to assess your sensitivities; there are really talented interrogators in counterintelligence, whose full-time job is to fuck with you in subtle ways. To poly a person at will is very much a power move, and some guys fucking love it. But that's a different story all together. Most of the time it's a formality like everything else. In reality, people don't have remotely enough bandwidth to pursue stuff like that unless there's a genuine investigation. But office politics people will office-politique.

Unpopular opinion: private companies should poly people more often in hiring, it could prove more useful than other arbitrary kind of culture fit interviews. Food for thought.
