This papers describes interesting research into the question of whether trees communicate with each other using the opportunity afforded by a solar eclipse to measure electrical signals in and between spruce trees in the Dolomites Area of the Italian Alps.

The resulting analyses indicate that trees do anticipate events like this hours in advance, possibly depending on the age of the tree, with older trees potentially having a memory or anticipatory function for events that are cyclical and predictably timed.

The plan is 96 ports total for my own use, split across two 48-port 1U switches. And that's something that is now well within reach: I have the power boards assembled and ready to go, I have the FPGAs and PHYs and (not populated) line card boards in hand.

(EDIT: clarification, the plan had been 96 ports total since at least 2015, since that's what I had in existing Cisco switching. The major scope creep over that time was deciding that 2x 48 port switches with a bigger FPGA would be a more power efficient, easier to build, and generally superior design to 4x 24 port)

All that's left hardware wise is to design the main logic board with the FPGA, processor, and SFPs, plus the mechanical and thermal design of the 1U chassis. I've been focusing on firmware due to the tariff situation and wasn't planning on spinning the production-ish hardware for quite a while.

I don't plan any further scope changes now that I've e.g. already put in the production line card PCB order and mostly finalized the fabric architecture. I'm just holding off on the final logic board design until I'm sure about, for example, whether I'll want external packet buffer SRAM like LATENTPINK had or if I'll be fine with the KU5P's internal memory resourecs.

As far as the probes go, yes the antikernel.net site is way out of date and I've been too busy to refresh it.

* The AKL-PT1 did a kickstarter and I shipped probes to backers, but I stopped selling them because the fixed tip/ground spacing was too awkward and made it difficult to use.

* The AKL-PT2 (first gen solder in probe) was for sale for a while but extremely fragile, only 4 GHz bandwidth, and also had fixed signal/ground spacing.

* A few in-between designs were total flops and never reached the point of shipping a single unit

* The AKL-PT5 (second gen solder in probe) is >16 GHz bandwidth and has a flexible resistor based solder-in tip and a much nicer form factor. R&D is done but I ran into supply chain problems with the specialized resistor it needs (9 month lead time, poor yield, etc). I think I've mostly worked around those issues and I have a PVT run of a hundred units in the pipeline now. Fingers crossed they'll be hitting Digikey in the next 6-12 months.

I thought languages such as Rust and flamegraphs and etc were supposed to help us avoid doing all this testing and optimization right? Like I use the built in analysis tools that come with cargo and such and what I have on my os, tools like cutter or reverse engineering tools. Even on python I use the default or standard profiling and optimization tools, I wonder sometimes if I am not doing something enough if the default tools thats recommended should cover most edge cases and performance cases right?

I HAVE MY EX BACK TO ME WITH THE SOLUTION FROM Dr. SHAUN MURPHY. I came in contact with Dr. SHAUN MURPHY. Through a testimony written about him, I have also encountered many testimonies about how he has been helping others with their life. To get back with an ex is one of the innermost feelings many people would love to experience, especially as those memories with our ex always cloud our mind when someone else does some of those things our ex used to do. I was a single parent for almost 6 years, and though my ex-husband was far away from my kids, I still wish someday he would return to me. I encountered this spell doctor, Dr. SHAUN MURPHY. It helped me with my wishes, and I am happy to say I am back with my ex-husband. He assured me that the result manifested within 48 hours, and our love and connection were restored amazingly. If you want to get back with your ex successfully, contact this great spell caster with HIS EMAIL: doctormurphhy@yahoo.com‎

Which begs an important question. To what extent is American healthcare built around liability?

There are a lot of innocuous things built into the healthcare system, like gating the cough syrup that gets you really high easily, behind a visit to a provider, that many people are just ignorant of as a virtue of the current setup.

When we disrupt fields that we are not experts in we often miss oceans of nuance.

If you are really into good quality audio, I'd recommend a used

Fiio M11 Plus

It's really good, but even used about 450 bucks. This might be too pricey, so you could then go for a

Surfans F20

like already recommended (https://www.rockbox.org/wiki/AIGOErosQK). It has no balanced output, but is about 120 bucks and supports Rockbox.

If you more into Android and streaming, you could take a look at the

Hiby M300

which is also a budget device, but has a pretty modern Android and is a bit more portable than a smartphone.

Maybe it's also worth mentioning Qobuz (https://www.qobuz.com/), the high res music streaming service. Many audiophiles are into this, while I'm not using streaming services at all.

I personally use an old iPod Nano 7g and as backup device my Android phone with Substreamer / DSub and self hosted navidrome. Not hi-res, I don't need this :-)

When I am in hill climbing gear, I turn more revolutions on my pedals than the tires turn. The higher that ration (pedal turns:wheel turns) the 'easier' it is to pedal, but the more turns you need to go forwards.

A bike that is a 1:1 'fixie' would indeed struggle with hills like the OP suggests. However, this bike has a secret hub within the wheel that does gearing, so you have (iirc) 3 ratios you can use to get up to speed or climb hills.

> This idea is absurdly underbaked…other commenters mentioned that it’s going to flip, and it is.

Assuming the rear is loaded with cargo, you'd have a low center of gravity over two wheels. To tip over, one of the rear wheels would need to come up, but that's where most of the weight is.

And I suspect the engineers who built this probably didn't just completely miss "oh wait, what if it tips over!?" Unless you've a) got some experience with this domain and b) got some experience with this bike, I don't know how you could know this bike is going to flip over.

The force itself is `G * m1 * m2 / (r^2)`. That's a pure magnitude. The direction of the force is just the unit vector going from m1 to m2. You need it to be a unit vector or else you're multiplying up to something higher than that force. However, I don't get why you'd ever cube the 'r'. Never seen that. I don't think it's right, tbh.

> it's just a way to be reasonably confident that _if you audit the code_

Why do we pretend this is easy many times in conversation about dependencies? It's as if security bugs in dependencies were calling out at us, like a house inspector looking at a huge hole on the floor of the house. But it's not like that at all, most people would inspect 99.9% of CVEs and read the vulnerable code and accept it. As did the reviewers in the open-source project, who know that codebase much more than someone who's adding a dependency because they want to do X faster. And they missed it or the CVE wouldn't be there, but somehow a random dev looking at it for the first time will find it?

In fact, if to use dependencies I have to read and understand the code and validate it, the number of dependencies I'd use would go to zero. And many things I would be locked out of doing, because I'm too dumb to understand them, so I can't audit the code, which means I'm definitely too dumb to replicate the library myself.

Asking people to audit the code in hopes of finding a security bug is a big crapshoot. The industry needs better tools.

I appreciate the value of AI in my own work, but "they’re very good coders" and "they make trivial mistakes or hallucinate" seems incongruous.

For me, AI tools shine when I know enough about a topic to quickly error check, but not enough where I can code fluently without documentation. I'm sure it will get more useful over time, but that's where it's been for me for the last year or so.

> and chips (Tensor)

Is there actually any hard data out there comparing the NPU on the Google Tensor G4 vs the Apple A18? I wasn't able to quickly find anything concrete.

I mean Apple has been shipping mobile NPUs for longer than Google (Apple: since A11 in 2017, Google: since 2021), and are built on (ostensibly) a smaller silicon node that Google's (G4: Samsung SF4P vs A18: TSMC N3E). However, the G4 appears to have more RAM bandwidth (68.26 GB/s vs 60 GB/s on A18).

No, they will not, actually. At least in the lower-middle, Medicaid spectrum of care.

Physicians at this level serve the labor market, and everything they do is ordered to keeping you able-bodied and working and on the job and not taking sick days.

They have always been reluctant to dispense excuses from work, to document any sort of disability related trouble, or to give advice that does not involve more exercise or more medication.

I have honestly approached multiple doctors in multiple health systems to complain about fatigue, syncope, and exhaustion, and they all go to extraordinary lengths to deny that anything is wrong or that anything should change.

I ride a cargo bike through the city, probably 100 miles of commuting through a downtown corridor every week. Pedestrians are basically zero worry relative to cars and people on those rental scooters.

I have an e-assist on mine, so I can absolutely outrun anyone menacing, and biking so much gets you in healthy enough shape that most folks think, "Nah, I'll wait for an easier target." And if that didn't do the trick, pepper spray is a reasonable option.

People on foot are really, really not the worry. Mindless drivers who think they are invincible so they don't pay attention to their environment are FAR more dangerous.

> The other guy was correct while you are the one who posted the fallacy. If using heat from nuclear sources to drive aluminum production were feasible,

Aluminum reduction is electrochemical, not thermochemical. Yes, the pots are hot, but they are kept hot by resistive dissipation as the alumina is electrolysed.

(There is some chemical energy contributed from oxidation of the carbon electrode.)

The reason uncertainty goes up the closer we try to observe something in physics, is because everything is ultimately waves of specific wavelengths. So if you try to "zoom in" on one of the 'humps' of a sine wave, for example you don't see anything but a line that gets straighter and straighter, which is basically a loss of information. This is what Heisenberg Principle is about. Not the "Say my Name" one, the other one. hahaha.

And yes that's a dramatic over-simplification of uncertainty principle, but it conveys the concept perfectly.

From the linked comment: > Mandatory reminder that "agentic coding" works way worse than just using the LLM directly

just isn't true. If everything was equal, that might possibly be true, but it turns out that system prompts are quite powerful in influencing how an LLM behaves. ChatGPT with a blank user entered system prompt behaves differently (read: poorer at coding) than one with a tuned system prompt. Aider/Copilot/Windsurf/etc all have custom system prompts that make them more powerful rather than less, compared to using a raw web browser, and also don't involve the overhead of copy pasting.

I probably should've mentioned that I don't actually have any familiarity with StageX, I did write that at some point but must've accidentally removed it from my reply while still working on it. Even so, I had a feeling the example wasn't a good example of how to actually use it properly, and I feel a little bad because I didn't really mean to critique StageX because of that particular issue, I just thought it was a good example of how Nix differs (Nix enforces purity, Dockerfile builds don't.) It seems like with StageX the goal is to ensure that the build is bit-for-bit reproducible as this would be a relatively good assurance that the inputs are also reproducible. On the other hand, it might be relatively hard to actually debug what went wrong in the more subtle cases where the inputs are not reproducible, since presumably the main artifact of this will be the output differing unexpectedly.

I'm definitely biased as a person who works on Nix stuff but I am not an absolutist when it comes to any of these things, based on what I'm reading about it I'd happily rely on StageX if I wanted reproducible OCI builds (and didn't feel like using Nix to do it, which has plenty of complexities on its own as nice as it can be.)

@>70k isn't a median income, it's much more than it.

https://www.bls.gov/news.release/pdf/wkyeng.pdf

>Median weekly earnings of full-time workers were $1,194 in the first quarter of 2025.

Extrapolates to 62k/year. I don't know what else to say here.

>. So somebody earning $50k and working 60 hour weeks would be earning $87,500 which would put them in the top quarter of all earners in the US

Yes, work 50% more than the median and you hit the 75% mark (above 50% of the top half). The math seems to math out. But thought we wanted to not worm ourselves to death these days?

>straight out of high school, and with 0 debt.

Well, no. Not straight out of high school. You need to compete for a role among unions (which seems to be a hurdle the poster above passed, or is confident of passing), then complete an apprenticeship for a few years that may either be unpaid or pay significantly less. Then after that you become a journeyman and start to get that pay.

There's still a near college level of training where you need resources to survive that your apprenticeship isn't covering. Resources that may or may not include parents covering room and board (and in that case, sure. You can survive on anything That pays anything if the biggest expense is paid for). That's sadly a growing luxury in modern society, though.

>But the interesting thing about trades is that people end up enjoying them.

I work in games, so yea. I get it. You sacrifice comfort and maybe even health for furfillment. But I can still recognize in my industry when that passion and engagement is being exploited while still choosing to participate it.

Well, eventually I recognized it. Gaining 60 pounds and having an emergency room visit finally knocked some sense into me.

Right, so as you've pointed out, chatgpt wouldn't have helped me in any way.

And, for the record, I was referred to a Urologist. The doctor was able to say "something isn't right but I don't know what" and he referred me to a Urologist and got my ultrasounds.

No offense to uh... AI... but it's not very good at being humble. It seems hubris wasn't in the training data. It's quite difficult to get an LLM to say "I don't know". Usually you have to prime it or ask leading questions, which at that point you already know that it doesn't know so therefore trying to elicit that response is worthless.

It doesn't, I never said it does. In fact I'm just adding on, not arguing.

> but again, a solution might involve teaching men to control impulses better, more like women do.

Yeah I agree that will definitely help.

> Ration of women vs men drinking/smoking changes with time and culture.

Somewhat, but I don't believe there was ever a time where women were ahead of men. I think pretty much for all of human history, on the topic of "stuff that can kill you" men take the lead. With the exception being pregnancy, but that's pretty self explanatory.

I think there has to be some hormonal component to this. It seems testosterone is not so good for addictions or impulse control. I don't have any evidence, although maybe some exists. It just seems... more than cultural if this has been a problem for as long as human history has existed.

Actually that is probably one thing that credit cards could do without legislational changes, by modifying their merchant agreements. Businesses would be salty about it, but the value of being able to accept credit cards would mean they'd have to suck it up and accept it. They'd have to put something about how by accepting cards, they agree that that agreement supersedes any other and that a payment cancelation or chargeback constitutes acceptance of cancelation for whatever service was being paid for by that card or something along those lines.

It never happened. I've heard varying versions of this urban legend from the late eighties through to modern time. The reality is that an LSD trip can cause physical discomfort, especially toward the end. Sometimes this discomfort is stronger than other times. For some reason, people have confused this with strychnine.

There is no avenue in synthesis or purification in which LSD and strychnine would come into contact. There is no benefit to cut LSD with strychnine. The amount of strychnine necessary to have any effects on humans is too close to the lower end of lethality to be a useful cutting agent.

That being said, there are side-products in LSD synthesis or purification from natural substances (e.g. ergot fungus cultures) can leave related substances as impurities. These can cause vasoconstriction, which is unpleasant. This isn't strychnine, and it's unlikely to be dangerous as small amounts of impurity. It doesn't feel very nice, and it can cause bruising. Or, people tripping can just bump into things and be clumsy. Either way, the explanation that this comes from strychnine is and has always been bunk.

It should be obvious, but please don't confuse any of this with an endorsement of the drug. That's a separate topic. The most I'll say here is that I don't recommend it.

At the speeds you can go on this, motorcycle is a bad comparison. Depending on the rear module used, this could definitely use most of the bike infrastructure in my city without a problem.

In my experience of dealing with loosey goosey languages (JS, PHP, Perl), 80%+ of the errors you will receive are because of the type system.

In PHP, if you look at your logs you'll see almost all the errors are checking an array with an index that doesn't exist. This is because people are using arrays as objects and then using strings as members. If you just use an object, this type of error is impossible.

So, we have to write `??` everywhere because anything can always be null and then it can break stuff.

And then you have errors with passing empty string vs null vs empty array to functions and getting unpredictable behavior. So you need to constantly check everything.

If you actually open up a function in a dynamically typed language, take your pick, you'll see something like this:

``` if (arg === '' || arg === null || arg === undefined || arg === []) ... ```

If you don't include checks like that everywhere, your code will break. You just don't know it isn't broken yet.

And, btw, something like PHP `empty()` is not a silver bullet either. Because it considers like a dozen different values to be empty. Which comes with it's own set of problems.

In a disruption in a tokamak, when the plasma collapses, the current in the plasma that goes around the ring decays. This creates an electric field as in a kind of accelerator called a "betatron". The electric field can accelerate runaway electrons to relativistic speeds. This beam can hit surfaces and melt holes, like a giant arc welder.

It seems that way if you judge them the same way you would human coders, but they’re different. They might be able to do things that veteran coders can’t without spending days on it, and fail at things that beginners can do in half an hour.

The only reason that the subsurface rock is cooler than magma is being able to conduct heat through to a cooler surface. When that surface becomes exterminatingly hot and remains so for a while the subsurface will be heating up too. Since the sun is estimated to remain a red giant for about one Gy it will become hotter than the surface.
