>But our animal bodies evolved to live in the dirt, no?

Evolving while existing on or tolerating dirt is not evolving -to- live in the dirt. It may very well be that some exposure to pathogens is beneficial, and some of that may be conferred by contact with animals (I know daycare does that job for sure), but I will still work to reduce my exposure to it within my home and on my body.

If I recall correctly, properly managing waste (human and otherwise) via sewage and plumbing has been a material contributor to decreased morbidity/mortality rates in the developed world.

I created https://anonchat.chat which is a simple wallet-to-wallet messenger on ETH and SOL. Login with any wallet (brand new, empty wallet works just as well)

I think I wasted my time building this because no one is interested. There's also a very similar App, Blockscan that has no users.

Any chance I can pivot this app into something meaningful or should I give up and work on something else?

The CIA was operating for a long time in Tibet and got the Dalai Lama kicked out. Taiwan wouldn't even exist if it weren't backed by forgeign powers, namely the US and UK. The US dropped 2.7 million tons of bombs on Cambodia. The US has conducted thousands of drone strikes in Pakistan, and of course, they fought a war in Korea.

Well, the question isn't what OpenAI's intellectual property is worth right now, or what you expect it to be worth, but what it is likely to be worth after OpenAI has become insolvent (and few/none of the current employees are working on it). The most likely causes for it becoming insolvent are probably that another company out-innovates them, or that the revenues never come in (despite OpenAI being a market leader). In either case, OpenAI's IP is unlikely to be sufficiently superior to the competition's to warrant a large premium.

I am not sure how differentiated OpenAI's IP is, so I don't have a strong opinion, but it seems to me that OpenAI is worth a lot more as a package than it would be as a collection of pieces.

I spent the first half of my career in ops, watching those alerts, escalating things, fixing stuff, writing EDA to fix stuff, working with monitoring teams and dev teams to tune monitoring, etc. Over time I worked my way into a dev role, but still am focused on the infrastructure.

The problem you’re starting to run into is that you’re seeing the monitors as useless, which will ultimately lead to ignoring them, so when there is a problem you won’t know it.

What you should be doing is tuning the monitors to make them useful. If your app will see occasional spikes that last 10 minutes, and the monitor checks every 5 minutes, set it to only create an alert after 3 consecutive failures. That creates some tolerance for spikes, but will still alert you if there is a prolonged issue that needs to be addressed due to the inevitable performance issues it will cause.

If there are other alerts that happen often that need action taken, which is repeatable, that’s where EDA (Event Driven Automation) would come in. Write some code to fix what needs to be fixed, and when the alert comes in the code automatically runs to fix it. You then only need to handle it when the EDA code can’t fix the issue. Fix it once in code instead of every time you get an alert.

The arrogance is not that they think they're the center of the universe. It is much worse.

I hear a lot of talk about how much pain you can inflict on people and how to extract the most value from that. Last I heard it was from a couple of media types discussing radio commercials. No care for their actual product for the end user - but an evaluation of how much people would suffer before tuning away.

Actual professional pride and care is sooo last century.

Such a sophomoric response. It does not matter how large your storage use is exactly. The point is that nobody is going to pay to replicate that data in multiple clouds or within multiple regions of the same cloud provider.

Btw, I'd love to have a link to where I could buy an SD card the size of a pinky nail that holds terabytes of data.

>‘Tesla Dilemma’: Elon Musk is destroying Tesla’s profitable car business, but at the current valuation, his lies about self-driving and robots is what is keeping the stock alive.

It's crazy and nuts but it makes sense. The choice is between keeping hype alive and delaying doom or doom now.

Tesla

P/E: 254 PEG: 116

For a car company with $1.46T market cap and modest revenue growth in last 12 quarters (3 years) those numbers are ridiculous.

But I have both android and iOS devices at home and the liquid glass is just......not that nice(imho). I hope I'll get that feeling of awe with computers at some point again.

It does not. In fact most of the big enterprise software doesn't because enterprise won't allow it, or it's running airgapped.

Enterprise software is licensed based on support contracts and audits. "trust" is actually more present because a large company or the government can't just vanish if they're in license compliance breach and can later be sued to recover costs.

This is basically Oracle and IBMs business model: let people install whatever they want, then request a spot check if usage and discover the license breaches which can be rectified by buying more of whatever now that it's business critical.

I used Graforth, that was so cool! I owe you a beer for pirating it. I also (like most Forth enthusiasts) developed my own Apple ][, based on FIG-FORTH, with its own graphics libraries and PRODOS integration, and used it to write terminal emulators.

Then I discovered Mitch Bradley's Sun Forth (aka ForthMacs, Open Firmware, IEEE 1275-1994), which was originally based on Langton and Perry Forth 83, but has a metacompiler and can target many platforms and word sizes and cpus.

More thoughts and links on Mitch Bradley, Open Firmware and Forth programming:

Has anybody else ever had the dubious experience of using "Cap'n Software Forth"? That's what John Draper wrote [Sl]EasyWriter with (which he wrote on work furlough from the Alameda County Jail). During the 90's SF Raves scene I would always carry some emergency tobacco around as repellent, just in case I ran into him.

https://en.wikipedia.org/wiki/EasyWriter

http://www.art.net/~hopkins/Don/lang/forth.html

>The first Forth system I used was Cap'n Software Forth, on the Apple ][, by John Draper. The first time I met John Draper was when Mike Grant brought him over to my house, because Mike's mother was fed up with Draper, and didn't want him staying over any longer. So Mike brought him over to stay at my house, instead. He had been attending some science fiction convention, was about to go to the Galopagos Islands, always insisted on doing back exercises with everyone, got very rude in an elevator when someone lit up a cigarette, and bragged he could smoke Mike's brother Greg under the table. In case you're ever at a party, and you have some pot that he wants to smoke and you just can't get rid of him, try filling up a bowl with some tobacco and offering it to him. It's a good idea to keep some "emergency tobacco" on your person at all times whenever attending raves in the bay area. My mom got fed up too, and ended up driving him all the way to the airport to get rid of him. On the way, he offered to sell us his extra can of peanuts, but my mom suggested that he might get hungry later, and that he had better hold onto them. What tact!

As annoying and creepy as he is, he does have a lot of great stories to tell...

China currently can't make the high-performance, efficient, long-life jet engines that US & Europe make. The commercial market is heavily cost-sensitive, so they can't compete there currently as a result.

This doesn't matter so much for military purposes: they can easily eat the cost of a higher maintenance and replacement schedule on a smaller number of military jets with fewer hours on them.

This gives them more iteration cycles, speeding their building up of experience. They're catching up. Industrial espionage will help them along too, but not as much as the experience from engineering their own designs.

CPU usage I tend to see used for two things. Scaling and maybe diagnostics (for 5% of investigations). Dont alert on it. Maybe alert if you scaled too much though.

I would recommend alerting on reliability. If errors for an endpoint go above whatever yoy judge to set e.g. 1% or 0.1% or 0.01% for a sustained period then alarm.

Maybe do the same for latency.

For hobby projects though I just point a free tier of one of those down detector things at a few urls. I may make a health check url.

Every false alarm should lead to some decision of how to fix e.g. different alarm, different threshold or even just forget that alarm.

Personally, I'm not religious. But 20% of Americans believe that the Bible is the literal word of God. Is it really so crazy for one venture capitalist to believe that the Antichrist is real?

Part of the freedom of religion is accepting that other Americans really do have religious beliefs that differ from your own sometimes, and that's okay. It doesn't mean you need to support the policies that he supports. But we do need to share this country peacefully with people who don't have the same religious beliefs that we do.

I couldn't imagine worshipping aliens even if they were powerful enough to be indistinguishable from gods.

I also think that if such powerful aliens (or actual gods for that matter) were to exist, they wouldn't give a rat's ass about whether we worship them. Because we'd have nothing to offer them. It's like us stepping on ants without thinking about it. Their world is so limited it's meaningless to us. If any gods existed we'd be the same to them.

In any case my intuition will always be to fight hostile authorities, even if its futile. I would never be able to be in the military for example.

Let's say the cable gets detached really close to the geosynchronous tether point (that's the worst case, right?). How much of the cable will burn up in the atmosphere? What is the density of the carbon nano-tube / graphene ribbons? And what is their terminal velocity? Has anyone proposed dimension of a graphene ribbon tether? Like it is 300 mm wide by 0.01 mm thick?

The MiG didn’t reach 37km in level flight, which is probably where Mach 15 @40km comes from. Instead the MiG was doing a nearly parabolic trajectory starting with Mach ~3 worth of kinetic energy.

The NASA X-43A hit Mach 9.6 as an air breathing engine (test used a rocket at lower speeds for cost reasons) which in theory should be capable of ~65 km assuming it could survive a similar maneuver. Actual limits are heavily influenced by how much thrust you can generate while slowing down etc not just max velocity.

So yea no actually built air breathing aircraft can hit space, but it’s within the realm of possibility.

Honestly fair enough. And for the record, I do not want the US and Europe to stop cooperating, I just think that we have lost much of the intrinsic cultural reasoning for allying in the first place. But at the same time, your statement about the urban/rural culture gap kind of refutes my point anyways. Either way, we still have much bigger fish to fry with Russia and China on the horizon, so we definitely have more in common with each other government wise compared to the rest of the world.

I think it is just cheaper as long as you have cheap/free water you can evaporate. Otherwise you would have to have to run a closed loop cooling system using regular AC tech (eg. some low boiling point liquid at low pressure, compressor, evaporator/condenser), that would be presumably more expensive to operate (but would not need lots of water to evaporate when operating).

replaced all of their vending machines with machines that require me to install an app(!) to purchase a product

I saw this at a Simon mall recently.

I took a picture of the machine. Across the front of the door is a banner which reads:

1. Scan the QR code 2. Create profile 3. Scan again to unlock door 4. Close the door 5. You're one drink closer to a free drink!

I'm not going to jump through hoops like a circus animal for a Mr. Pibb. I used the water fountain instead.

IMO a big problem with Liquid Glass is that you're trying to recreate an effect that's highly reliant on the sense of depth we get from binocular vision in a 2D screen.

When looking at glass in real life, your left eye and your right eye see slightly different refraction patterns since they're looking at the surface from slightly different angles. It might be minimal, but light refraction patterns can change a lot when looked at from slightly different distances. This is depth information our brains automatically interpret, and it makes easy to tell what is "the glass" vs what is "on the glass".

On a 2D screen both eyes see the same refraction pattern— your eyes are receiving no depth information. It's just up to color contrast and semantics to figure out what's part of the glass vs laid on top of it, so things that might look legible or easy to tell apart on physical glass will look messy on the screen.

Its too easy to switch providers when theres a billion dollars a year at stake. If youre an apple exec who sees that the company is spending 10k per employee per year why wouldnt you start an initiative that cuts that spend to 1k per employee per year? Then you can go to the board and say you personally saved them all that money and get a big promotion.

The rules aren't important. What's important is, it's linear. Every time I throw this ball, a hundred different things can happen in a game. He might swing and miss, he might hit it. The point is, you never know. You try to anticipate, set a strategy for all the possibilities as best you can, but in the end it comes down to throwing one pitch after another and seeing what happens. With each new consequence, the game begins to take shape.

That's not how I remember it. Back in the day the first thing you did was disable the Aero stuff to claw back some performance on Vista.

That said, who knows how efficient the implementation is compared to other changes in iOS 26. I turned liquid glass off with "reduced transparency" because even 1% extra battery usage for it would be too much even though I kinda appreciated the new look.

A single session of binge drinking does not an alcoholic make. An "alcoholic" is defined by their regular abuse of alcohol, not a single instance of binge drinking.

Binge drinking can obviously be a symptom of alcoholism, but IMO it's not appropriate to declare people you don't know are alcoholics based on a comment about an theoretical instance of binge drinking.

> Is there any guide for us non-americans to help us gain enough grasp on the rules to, at least, understand the dynamics of the game?

If you've already read "no matter how many" and don't get it? Then no, you probably can't be helped.

It's not very different conceptually from cricket. One player throws the ball hard, another tries to hit it far away with a bat. If you hit it far enough, you get to run; if you run far enough before the other team throw the ball back, you might score some points. If you keep failing to hit the ball, you will (probabilistically) soon be out. If the other team catches the ball, you're out. If enough players are out, the teams swap sides and the other team gets to try hitting the ball.

The rest is details. You can find them in any of the videos or articles you've already failed to comprehend without this primer.

Sonnet 4.5/CC is faster, more direct, and is generally better at following my intent rather than the letter of my prompt. A large chunk of my tasks are not "solve this concurrency bug" or "write this entire feature" but rather "CLI ops", merging commits, running a linter, deploying a service, etc. I almost use it like it was my shell.

Also while not quite as smart, it's a better pair programmer. If I'm feeling out a new feature and am not sure how exactly it should work yet, I prefer to work with Sonnet 4.5 on it. It typically gives me more practical and realistic suggestions for my codebase. I've noticed that GPT-5 can jump right into very sophisticated solutions that, while correct, are probably not appropriate.

Sonnet 4.5: "Why don't we just poll at an interval with exponential backoff?"

GPT-5: "The correct solution is to include the data in the event stream...let us begin by refactoring the event system to support this..."

That said, if I do want to refactor the event system, I definitely want to use Codex for that.

One can try to be more objective and far exceed others, specially in your area of expertise, but you won't grow all the way and outlandish ideas live on under topics rarely examined.

If you make enough effort towards objectivity for long enough you continue to find crazy obvious stuff you actually bought into all along.

To do a funny example: People use to attempt to make devices to communicate with the dead. What happened to that effort? Did we just one day decide it can't be done? What evidence do we have to support that conclusion? We can try argue it is unlikely to succeed. We have nothing to show that supports any kind of likelihood.

Then it must be stuff we like to believe?

> No maglev train I ever heard of travels at 36,000 km/h. This is about two orders of magnitude faster.

You think the problem is the speed itself, and not the fact that trains are close to sea level and at that speed would immediately explode from compressing the air in front of them so hard it can't get out of the way before superheating to plasma, i.e. what we see on rocket re-entry only much much worse because the air at the altitude of peak re-entry heating is 0.00004% the density at sea level?

> What do you think is going to happen to your circuit if you have an electrical potential difference of 1 MV over a few centimeters?

1) In space? Very little. Pylons that you see around the countryside aren't running in a vacuum, their isolators are irrelevant.

2) Why "a few centimetres"? You've pulled the 10 tons mass out of thin air, likewise that it's supposed to use "one kilovolt" potential differences, and now also that the electromagnets have to be "a few centimetres" in size? Were you taking that number from what I said about the gap between the train and the rails? Obviously you scale the size of your EM source to whatever works for your other constraints. And, for that matter, the peak velocity of the cargo container, peak acceleration, mass, dimensions, everything.

> For comparison, light rail typically uses around 1 kV, while mainline trains use something like 15 kV.

Hang on a minute. I was already wondering this on your previous comment, but now it matters: do you think the climber itself needs to internally route any of this power at all?

What you need for this is switches and coils on one side, a Halbach array on the other. Coils aren't that heavy, especially if they're superconducting. Halbach array on the cargo pod, all the rest on the tether.

Right now, the hardest part is — by a huge margin — making the tether. Like, "nobody could do it today for any money" hard. But if we could make the tether, then actually making things go up it is really not a big deal, it's of a complexity that overlaps with a science faire project.

(Also, I grew up with 25kV, but British train engineering is hardly worth taking inspiration from for other rail systems, let alone a space elevator).

That’s what I’d expect a basic setup to look like - region/space specific

So you’re minimally hydrating everyone’s data everywhere so that you can have some failover. Seems smart and a good middle ground to maximize HA. I’m curious what your retention window for the failover data redundancy is. Days/weeks? Or just a fifo with total data cap?

Hello everyone

I'm the founder of a project called *iKIP* — a triple communication phone concept that integrates *GSM, VoIP, and Mesh* communication in one unified interface.

The goal: Create a *semi-functional virtual prototype* (software only) that demonstrates the core interactions: - GSM: simulated standard cellular calls - VoIP: simulated internet-based calls using WebRTC or similar - Mesh: simulated offline calls or local communication (via WebSocket/Bluetooth emulation)

This is not hardware — it’s a *purely virtual prototype*, showing how the three channels work together within the same phone UI. The idea is to make the demo realistic enough to present to investors.

What I need: A *software engineer (JS/React, WebRTC, or network simulation)* who can: - Turn my current mockup into a clickable, partially functional demo - Simulate real-time communication between virtual devices - Record a short demo video (screen capture) - Deliver a clean GitHub repo + README explaining the architecture

Tech direction: Frontend can be web-based (React/Next.js or similar). VoIP and Mesh can use existing open APIs (no backend infrastructure required).

Compensation: This is an early-stage collaboration. I offer *up to 5% equity* in the iKIP project for the engineer who helps bring this prototype to life.

Deliverable: - Working virtual demo (clickable, responsive) - 1-minute demo video - Clear code structure on GitHub

If you’re interested, drop a comment or DM me. I’ll share the design files and the GitHub repo link privately.

Thank you — Adam

7. 7.You skip town together.

Peculiar formatting. Is this due to the archiving, or does the original double number every list item?

Before I read the article, I felt certain that the article really was about misplacing mortgages. At scale, almost everything happens a little bit of the time. IP packets get lost. An english bank goes rogue and issues "magic" debit cards that deduct withdrawals from random accounts. TPM modules lock up. BMCs quit responding.
