{Leeches have a reputation for clinging stubbornly to their hosts, but one species has a more acrobatic side: It leaps through the air.

The horrifying discovery was made by a pair of researchers during two trips to Madagascar in 2017 and 2023. Reporting today in Biotropica, the duo describes Chtonobdella fallax, a leech species common to the island, rearing back like a snake ready to strike before springing forward, straight-bodied, across a leaf or from a bush onto the ground. With three jumps in just two short recordings, the researchers say, the species is likely a frequent leaper—and executes the move gracefully, despite its clumsy landings.

The debate over whether land-dwelling leeches can jump onto their hosts has festered for more than 130 years. Written accounts of the behavior date as far back as the 14th century. But with no hard evidence to those anecdotes, some experts have argued those leeches may have simply fallen from overhead or grabbed onto passing bodies from lofty, leafy perches. Now, scientists have the video to refute this.

Whether leeches use their hops to land on hosts remains to be seen. But if they do, it could be a boon for biodiversity conservation. Scientists searching leech guts to unravel which animals they’ve fed on may interpret their findings differently if the slippery bloodsuckers can soar, painting a more accurate picture of animal communities in the creatures’ Indo-Pacific homes.}

The existence of absurdities like this, and everything there surrounds it is beyond obscene when there continues to exist poverty - in the same places where these are being carried

Everyone involved at every level should be ashamed of themselves and should be significantly questioning whether or not their life is a net negative on the world
> ironically you can use this tool to install itself

That isn't irony. Irony would be if it couldn't install itself or if it uninstalled itself. So your use of irony was itself, ironic.
> If you want actual security, you have to go for a challenge-response scheme

Sure you just have to accept that you're now vulnerable to Denial of Service attacks, or just DoS due to unrelated service infrastructure outages caused by things like backhoes.

> much less orient them consistently for the bond process to work?!

It's not all that consistent. They have a 3% failure rate. And you have to accept a unique map of "broken chips" with every single order you receive.
> a per-chip price of nine cents

That still seems expensive for a $3.75 metro fare.

2.4% of the cost of your ride is the chip in the ticket itself? Maybe it's worth it because it lets them eliminate mechanical ticket-reading and unify paper tickets with other NFC payment methods.
To put it in a way that might be more familiar to someone in tech, it's like buying an absurdly powerful computer to show off to friends. In all likelihood you don't actually need a 64 core, 128gb monster with dual 4090s, but you might want to be the kind of person who does need it and use it for the kinds of activities you imagine such a person might do. For computers, that might be playing a game at 16k at 240hz. For a purse it might having something appropriate to a gala or looks good in Paris. That's why luxury brands sell lifestyles, not extol the product itself.
In the Kargil War both sides deployed multiple divisions, and the Sino-Soviet War armored units were employed. Sure, neither side came close to using nukes, but they were still at war. It just goes to show that war between two nuclear states is possible without nuclear weapons being employed.
Wow I never actually thought about what is happening at the hardware level during sleep. The thought of a trickle charge going to RAM to keep the data alive while everything else sleeps is really cool.
Cars in cities rarely travel quickly, spending lot’s of time stopped at traffic lights right where people cross the street or stuck in traffic.

The squeal of a worn out brake pads is largely mitigated by regenerative breaks which increase brake lifespan.
The productivity boost is highly subjective, it depends a lot on your work. Do you edit files a lot or spend more time thinking ? Do you use some graphical tools on the side that forces you to grab your mouse anyways ? With AI tools now, where you can now basically select a file and prompt "rewrite all in snake_case" in VSCode it's becoming even less evident. I think the biggest gain from vim is simply if you're more happy using it or not.

Most people in Singapore try to food from China if possible.
I think it’s not buying the shares “instead” of buying the thing, it’s also buying the shares and the thing.

Because yeah, not buying things you want to watch your money high score go up is a pretty sad way to go through life.
I mean, the site is pretty blatant viral marketing for both his drop-shipped-hats-from-china side hustle and (I'm going to go out on a wild limb here and guess) his employer's ML-dataset-management-related startup.

I wish cool stuff like this wasn't always sullied by the slimy feeling from it only being done to draw attention to some startup sitting smack in the middle of the trendiest buzzwords of the month.
That convention is the result of identifying current flow as being the movement of that which we identified as positive charge.

It's not a convention that like charges repel.

If we agree that current is the flow of positive charge, then it has to go away from positive, toward negative.

Using positive quantities for current and charge is a good thing; we aren't constantly dealing with negative numbers to measure common situations like how much current is flowing through a wire.
An ICE engine is vastly louder stationary at a stoplight or stuck in heavy traffic. Both of which are is really common in cities.

Regenerative braking is also vastly quieter.
Feels like an incredibly shallow take on this technology. I predict this article will age horribly within a decade.

IMO if you can’t see the difference between crypto and LLMs, you aren’t paying enough attention. I think it’s much closer in impact to the internet than to crypto. Just because something is wildly overhyped, doesn’t mean that what’s underneath the hype isn’t huge.

There’s tons of value in AI, the only questions are how far will this improvement curve go before leveling off and how long will it take to usefully integrate the technology into various domains. The tide will go out and we’ll realize that many emperors have no clothes, but there will be many AI companies that have strong understanding of the reality of the tech, have strong technical and business fundamentals, and will be well positioned to become Fortune 50 companies.
The people who buy these bags cannot spend all they have, even in 10 lifetimes.

Don't worry about them. They'll be fine.
Cold take, assuming because completely AI output is not amazing that nobody is going to use the AI more intelligently than prompting for the finished end product in one go.

Artists use stable diffusion like a magic paint brush to transform sketched compositions into exceptional art. Writers use it to quickly trial ideas, generate fairly good dialogue and create a feedback cycle even when they don't have readers. Just because completely AI generated images/writing aren't amazing _NOW_ (and that deserves the emphasis), doesn't mean that they can't be mined for nuggets of gold.
> Cultivating the meat that sells at a mass-market price is the real challenge and one I wouldn't bet on anytime soon, not even by 2030.

Given the money going into lobbying states to make it illegal in the US, I can only assume that it must have some chance of success.
Most road noise and even pollution comes from tires, not a gas burning engine. I lived about a half mile from an xway once. You'd hear an occasional jake brake or loud motorcycle, but by far the most annoying thing was the constant whooshing noises of normal cars passing by.
... or by marrying into it. Or, by owning things that increase in value.
Mifare is what’s been used in London’s Oyster cards for 20 years (not the ultralight ones mind), and Hong Kong for even longer.

However oyster really is in its way out for most uses. contactless and especially a phone is far more convenient for non season use, and far less wasteful.
Yeah, there's some bullshit about device trees vs. ACPI.
> The ? is not really the issue here.

Based upon the way the code was written, it was, at least in the mind of the author. They forgot they could exit scope there. They clearly didn't _intend_ for that outcome, but ended up with it anyways, possibly out of habit, and possibly because a single impactful sigil like that is easy to miss in review.

I get that technically it didn't cause the memory leak.. but just look at the way that was written initially... it obviously led to it _within_ that particular structure.
It's funny to see such a large library in the USA and not the UK.
I was a happy user of this plugin and would still recommend it, as it is indeed easier to use. The problem is that I ran into a bug [1] that would break the rest of my Gimp install. Note that the plan to resolve it is "convert the resynthesizer plugins from Python 2 to Python 3" but AFAIK this hasn't happened yet.

This bug occurs in one computer but not in the other. And once I discovered G'mic I honestly lost the drive to dig deeper into why this happens.

I delayed learning vim because I couldn't close the program, really.

And because it made no sense to me to have a modal editor.

Now I use vim mode everywhere is available, also in Google Colab and in Firefox.

At the beginning, you people shouldn't waste too much time editing vimrc. I admit that some plugins are exceptional, like startify, markdown, vim plug etc
A big problem with the idea that “people don’t want small cars” is that that sort of statement comes from the car manufacturer looking at new car sales. People who want large trucks and SUVs are willing to buy new. People who want a small car have the option to buy a new 2024 Honda Civic, or they could spend significantly less to get a used Honda Civic (in normal economic conditions). Since the manufacturer only profits of of new cars, they have little incentive to sell any cheap or small cars since they compete so heavily against last year’s model at the used car lot.
I'm looking forwards to the day they somehow manage to link a National Railcard to a contactless bank card.
As a survivor of communism, I sigh every time I see this ideology that killed countless millions still being pushed in places where other inhuman ideologies (like fascism and its ilk) will attract a swift ban.
No they are not. Electric cars are notably quieter under 50 mph. They are notably quieter at all speeds really.
LMVH is very succesfull in selling luxury to the middle and lower classes. They really found a growth market there.

I love the Enlightened Hacker News Commenter who can’t wait to share how they are different from other people when it comes to marketing.

Thank God for giving Daniel to the world, and Daniel for giving the world Gentoo and the ability to run your own Linux setup however the fuck you want.

Ages ago people warned Lennart would start doing fuckery like this, but apparently all for nothing.

What's next? Replacing the Linux kernel because it "isn't good enough" according to mister Poettering?
This is the London system we’ve had for a decade, it was licensed to other areas a few years ago.

I found myself in Paris having to cross the other day and forgot how terrible the old way of buying tickets was, amazed that it’s still the norm in so many cities
> Like what, there's Tiktoks advising young dumbasses precisely what they need to steal and joyride cars.

Yeah, because cars are valuable and joyriding a stolen car is impressive and cool to lots of teens. Getting a free ride on the bus is like negative street cred.
If we make an oscillating circuit by hooking up an inductor and capacitor and set it in motion, the devices are constantly switching their terminal designations between anode and cathode with each zero crossing. The terms are completely useless, except when talking about vacuum tube circuits and such.
Thing is, in most EU countries, tech salaries are way lower than US.

> Average car on the road in the US is 12.6 years *2 = 25.2

Hmm... I was naturally thinking about the country I live in (Palestine/Israel), but then I remembered I see a lot of old cars in US movies. Guess I'll take your word and assume that's more like the global average.
Wow, this is incredible. OP you (I?) should train a few models with different personalities/tasks and pair them with the 5 GitHub Monaspace fonts accordingly, allowing people in multifont programs to easily get different kinds of help in different situations. Lots of little ideas sparked by this… in general, I think this a good reminder that we are vastly underestimating fonts in discussions of UI (and, it appears, UX in full!)
> high-effort labmeat become more economical for Singapore than importing meat?

When you would be able to import the labmeat ingredients for at least 8x times the result weight of the imported meat.

Where S. would get these ingredients domestically?
> Maps are useful, but they don't understand the geography they describe. LLMs are maps of semantic structures and as such, can absolutely be useful without having an understanding of that which they map.

That's a really interesting analogy I've never heard before! That's going to stick in my head right alongside Simon Willison's "calculator for words".
A* is definitely AI... Why would someone say it isn't?
I don't really know the state of moral understanding, but I do know people, even intellectuals, can't separate their personal ideologies from their work, so they're not really capable of objectively figuring this stuff out.

I'm sure we can at least make some judgements about whether a set of morals is better or worse than another, but all the obvious cases are already solved and people strongly disagree on the ambiguous ones where they really have no idea.

One big moral concept is individual freedom vs long term survival of the system of social order they belong to. You can't have individual freedom without a society to protect it but you can't sustain that society without restricting people's freedoms (eg. military conscription). It's popular today in the west to value the individual over the future of their society, but a lot of history and the rest of the world is the opposite. People from these two camps seem to be blind to the weaknesses of these underlying assumptions, so they end up with moral ideas that seem totally immoral to each other.
> The lottery picking up the slack so the general fund doesn’t have to do all of it is the whole point.

That’s identical to the lottery just putting money directly into the general fund. Unless the funding source results in an increase in total funding this stuff is pure theatre.
NHS patients affected by cyber-attack may face six-month wait for blood test
Thunder Bay, Ontario. Pop. 110k. We still have the sort of carnival-style paper tickets. I would guess that most smaller cities don’t have fancy NFC tickets.
Numb and Number
Most metro stations have a much simpler way for travellers to figure out what to do: of loads people who do know how it works, ahead of and beside you.
Two points to consider, one against and one for.

1) It's a small island, but it's also a major trading port. Which means its whole economy is already geared towards importing food from neighboring countries.

2) On the other hand: no domestic industry to disrupt! No domestic farming groups lobbying against meat substitutes, which may push research/distribution furhter along.
Just use a weight on the string with a configured go fast length and go slow length for your motor to observe
It seems like all the arguments there are predicated on the "meat" being actual muscle cells in a vat, though. Wouldn't it be just as likely that the successfully engineered food ends up being just, like, kelp with GM'd amino acid byproducts or something? Or chicken-of-the-woods with more random proteins thrown in? (I mean as long as they don't kill the culture, it doesn't matter if it benefits the host organism.)

I'm sure that's all harder than it sounds. But I doubt it's the same "wall of no" as muscles in a vat.
Those both sound like AI to me

An example of similar computer can do that isn't AI would be arithmetic
I have even better idea, since your doesn't cover biggest noise polluters IMHO - have a technical check on the car/bike that includes noise levels above certain threshold. Now I realize there may be corner cases and so on, but in general this would work wonders and so far I see 0 being done there. The thing is, certain cars and many motorbikes simply can't be quiet regardless of rpms, even in 30kmh they wake many people up through closed window.

As somebody who lived just next to very busy street for few years, there are 2, or maybe 3 main noise pollutants in the order of intensity: 1) ambulances & police, they are really properly mental level and they don't care even on completely empty 3am streets, if I don't cover my ears when they pass me it physically hurts, even with my subpar hearing of higher frequencies; 2) motorbikes like choppers by default, and all tuned rest, aka Akrapovic and similar mods should be banned in inner cities, permanently, 24/7. And 3) sports cars obviously, but they posed the least problem even in uber rich place like Geneva where seeing a Ferrari or McLaren is not unusual, and nobody looks at Porsche or below. This goes also for performance variants of ie BMW, Mercs or Audis too in lesser way.
Good points, but diagnosis codes don't generally require any licensing fees. Depending on the use case those are usually either ICD-10-CM or SNOMED CT, both of which code systems are free to use.
Echoing the other comment, personally I find the C# interactive really frustrating to use. So close and yet so far.

I often find it quicker/less frustrating to just fire up a new console app project.

Last time I tried to use it I think it was even running an old version of .Net and you have to remember to switch the version.
Maybe this is more of a philosophical question, but to me “lab-grown mammoth muscular tissue” is not “mammoth meat” if it hasn’t lived a mammoth’s life. I doubt it would taste the same as the real deal. Of course it’s as close is we’re going to get, most likely.

The unbearable sorrow of Apple Weather
Also, Apple shares also do not replace the functionality of a phone, so the true opportunity cost of buying a premium phone instead buying a cheaper phone and spending the remainder on shares.

If you’re going to quote, make it an accurate quote :) I didn’t say per year. And the amounts of animals killed by pet cats are very much not accepted as 5. Maybe you’re presented with 5.

“Cats have played a leading role in most of Australia’s 34 mammal extinctions since 1788, and are a big reason populations of at least 123 other threatened native species are dropping.

But pet cats are wreaking havoc too. Our new analysis compiles the results of 66 different studies on pet cats to gauge the impact of Australia’s pet cat population on Australia’s wildlife.

On average, each roaming pet cat kills 186 reptiles, birds and mammals per year, most of them native to Australia”

https://www.nespthreatenedspecies.edu.au/news-and-media/late...

“scientific evidence does not support the popular use of cats to control urban rat populations, and ecologists oppose their use for this purpose because of the disproportionate harm they do to native wildlife”

“Surveys of cat owners find they often view the depredation of wildlife as a normal thing that cats do, and rarely feel an individual obligation to prevent it.[55] They may experience some level of cognitive dissonance toward the subject, because when surveyed they're more likely than the general public to believe that cat predation isn't harmful to wildlife”

I remember when this BS was being pushed about Wintel capturing the market and killing competition. Then mobile happened, Google and now AI - doomers just changed the brands doing the capturing.
I don’t really see why a chip is needed at all for single use tickets. Those have existed forever and there are a plethora of non-chip options ranging from the simple holepunch to the optical printed barcode or QR code.

I think these things are stupid, but they cost about the same as the difference between a pretty good car and a mostly good car. It doesn’t seem like the most insane hobby to me.

You can absolutely guarantee everyone isn’t going to follow that rule so why bother considering it? Also, nothing says you need to keep investments forever, a rolling fund where after X months you sell the stocks and repurchase based on current spending habits could work just fine at scale.
