Methodology seems kind of dubious:

> We introduce a novel experimental methodology that lets us quan- tify the performance of precise garbage collection versus explicit memory management. Our system allows us to treat unaltered Java programs as if they used explicit memory management by relying on oracles to insert calls to free. These oracles are generated from profile information gathered in earlier application runs.

Man, if you had that many nodes can you guys imagine how much cool tech you could build with that? Like you could literally rival Tor with one command. Or build a decentralized archive system. Yet, the only thing these nodes will end up doing is being used to prop up some losers ego. Literally what a waste. If you're going to commit crime at least do something cool.

That initial fixation on "position in the [social] hierarchy" in #1 can counterintuitively become self-defeating. Many people look at tricks of "climbing the social ladder" as potential signs of narcissism and instinctively steer clear. Unfortunately, that scoops up a lot of people like the author who just desperately wanted to break through an awkward adolescence!

Also counterintuitively, just giving up on that goal often leads to much more fruitful and lasting friendships. "Hi, I'm author. I'm abrasive and abrupt, excitable and sensitive. Interacting with me could be exhausting. Would you like to try? Please say yes or no."

Seriously, HN: if you saw one guy saying that to people, and another playing a ukelele at you as he "tells dramatics stories" about his life, which one would you choose to interact with?

This jogged some memories! Was working on something that used radio waves to detect objects and humans ~5 years ago, I see that we've come a long way since then.

One of our goals(abandoned) was to also extend to wifi routers, so I am excited to see continued interest in this space!

>I don’t know why you are downvoted, this is absolutely what happened semi-frequently until Reddit was finally forced to crack down on it.

What subreddits got banned because of that?

>The same thing happened on Twitter/X for a while where bots would mass reply to targeted users with gore and CSAM.

Did any of those targeted users get banned for this or was it just a form of harassment?

If you want to compare it against other languages you could look at The Computer Language Benchmarks Game [1], which is an ongoing comparison of various programs written in various popular languages. You should always take all these benchmarks with a pinch of salt though since they are never truly apples-to-apples. That said, Ruby seems to measure slightly faster than Python and Lua, slightly slower than PHP, and maybe 1 order of magnitude slower than Node.js, just to compare it with other similar languages.

Compared to itself from 10 years ago I think it's made great progress. Can't put a number to it but I wouldn't be surprised if it's 2x or 3x faster, especially with the "new" JIT (YJIT) enabled. The JIT comes with a memory usage penalty though. You can see some benchmarks over time (although not going back as far as 10 years) at https://speed.ruby-lang.org

> These people also have elaborate arguments as to why entities that might seem to meet every aspect of the definition of Empire even more than Israel-as-metropole does, particularly modern Russia, are not imperialist powers that amount to “it's only Imperialism if it comes from the US region of North America, otherwise its just sparkling international influence.

I think this last part does disservice to the rest of your argument. It's not "the same people", it's a subset. There are people capable of holding the view that all of those are examples of modern imperialism.

Also, some of us in Latin America have a reasonable justification for animosity against the US rather than against other (also imperialist) actors: we are "America's back yard" and they have been involved in toppling, undermining, threatening or supporting our governments as they see fit. The US' relative influence far outstrips all others. Russia, China, etc, while nonzero are comparatively far lesser influence factors and therefore are downplayed in our perception of the world.

As someone who grew up physically _and_ digitally sheltered, I am grateful for this article. It helped me articulate what I had wanted so badly, to be a kid.

Reading the comments gives me hope that there are still places safe enough and parents brave enough to let their kids run free. I hope to be this parent. And if I’m not, I at least hope I remember how important a digital friend can be for a kid who feels alone.

> Instead of letting an agent act directly as you, Windows spins up this extra workspace, gives it limited access (like specific folders such as Documents or Desktop), and keeps its actions isolated and auditable.

> Each agent can have its own workspace and access rules, so what one agent can see or do doesn’t automatically apply to others, and you stay in control of what they’re allowed to touch.

This actually sounds thoughtful. I know it's super popular to crap on MS about AI since the Windows Recall feature, but at this point it just seems like intentional bad faith. This feature here is something you'd have to turn on, anyway.

My favorite memory is following a map to a small isolated hot spring off of some random gravel road in the middle of nowhere. It consisted of a hot-tub-sized pool and a shower.

Whoever was there before had left the shower running. We were the only people there, and hadn't seen anyone pass us on the (dead end) road, so it must have been on for quite a while.

Only when I went to for my pre-soak shower did I realize that it didn't actually have any kind of user-accessible way to turn it off.

If Chess were a mobile game, you'd be forced to watch an ad after every three moves, the bishop would be on a timer and to use it again you'd have to wait 10 moves or pay using in-game currency, the knight would only be available if you bought the DLC, and the game wouldn't run unless you granted it access to all of your contacts.

I agree with you, but your statement doesn't seem to contradict my point. The reason I avoid LLMs is not that I'm too fearful to have my morals tested by their cultural/moral side-channels. The reason I avoid them is that they suck -- they are mostly useless in their primary function. And a convenient / fortunate consequence thereof is that I don't get exposed to those side-channels.

The specific examples in the thread, AFAICT, are about iOS, not macOS, and the person you're responding to specifically mentioned Macs. It's very hard to find examples of "things you cannot do on an Apple Silicon Mac due to Apple-imposed restrictions that you can do on a PC" that aren't pretty esoteric. (Unless you want to argue that the inability to plug in a better third-party GPU is due to Apple-imposed restrictions, which is debatable but defensible.)

Garageband was never even half as much fun as three POs plugged together - at least for me. Same way the all the guitar effect models running on my iPad aren't nearly as much fun as stomping on the Rat Distortion or Boss Chorus pedals I bought 35 years ago.

I don't know if people younger than me, who grew up with touch screen devices, have that same affinity for physical controls over touchscreens?

Yes, heavily disputed, to the point that there are widespread campaigns on the internet to normalize the various sovereignty claims under the guise of day-to-day conversation about those locales (e.g. conspicuously referring to them as being "in India" or "in Pakistan" or "in China"). For example, see the Google maps reviews for any landmarks in the area.

That’s an interesting concept. Can you talk more about how you imagine that affecting the market? My first reaction is that it wouldn’t solve the value problem at all. Yes you can charge more over time, and in practice it would actually limit how many you sell, but the problem is that the first buyer has no guarantee that the thing they buy is collectible, and thus a reduced incentive to buy. Every new sale devalues the original sale, even despite the low initial price. That might be offset by having lower prices for earlier buyers, but not limiting the edition size might also quietly eliminate the market for collectors.

Your idea reminded me of something I’ve thought about trying. It’s not the same concept exactly, but I do digital art sometimes and I was thinking of selling it with copyrights and the generator program included, and allowing the buyer to do whatever they want with it, including sell copies. The thing I was thinking is that I’d start with a low price per piece, and increase the price slightly every time I sell one, so the prices of my pieces would ramp up over time, rather than the prices of prints in a single edition.

The Ubuntu repositories curate both the legacy and more modern logisim fork:

sudo apt-get install logisim

sudo snap install logisim-evolution

Microcap 12 is also still available from the archive.org web cache, was made free, and runs in Wine64 just fine:

https://web.archive.org/web/20230214034946/http://www.spectr...

Microcap will handle both Analog and Digital simulations.

KiCad now also supports Spice, and reports it should import the free LTSpice libraries. I have yet to find a use case for the kicad sim option... so YMMV.

You are misunderstanding what Tiers are. Embedded architectures cannot be Tier 1 which requires running Rust compiler compiled on the architecture itself and testing stuff on with it. Only full desktop systems will be Tier 1, because those are the systems that you can run Rustc and all the nice desktop environments.

However most of the embedded world uses ARM chips and they are Tier 2 like thumbv6m and thumbv7em (there are still odd ones like 8051 or AVR or m68k, many of them lack a good C++ compiler already). They are guaranteed to be built and at the release time the tests still run for them.

Oof, nice one !

I was looking for some synths for my less-than-two-years kid, after seeing their face light up when I fiddle with my Lofi 12 XT in front of them.

I had all these criterias : -Something without any screens -Something simple enough -Something that could withstand some rough play

I looked and looked, was considering proper Aira Compact synths, but ended up with the antiquity of the Bliptronic 5000 from Thinkgeek. https://youtu.be/6rCfhF-fNb4 They love it, the buttons are beyond fun to them, but the knobs are quite hard to turn for a little kid (1st world problem, I know)

I felt they were too young for a Blipbox, and I also bought an Orba 2, we'll see how that one goes.

But I dreamed of such a device, with easy to turn knobs, and colorful display, something simple to modulate sounds and just hear melodies. Seeing how you created it is both inspiring and discouraging, as someone with limited free time and electrical knowledge, but, you never know !

This feels a bit like talking in hindsight.

With fossil power plants, the bigger plants were more efficient. This lead to centralization. We now find ourselves in a situation where you can end up with a lot of small/local generation.

What happened in Ukraine can probably happen in almost every developed country today as this was all built/planned in a different time.

OK, so this seems like a list of gripes about MacOS.

It's absolutely fine to have personal preferences on UX, customisability etc. This is why I swore off GNOME at the Gnome 3 transition and have never looked back, for example. If it doesn't work for you it doesn't work for you.

But it doesn't really support the assertion that you can't use the power of an M1 because of "how locked down everything is and most of that power is pretty useless".

Again, not trying to say "Thou shalt love MacOS!", but more that I don't think your points there really reflect something so locked down as to be useless. Just something with a UI you don't get along with.

They're great, but I feel their pricing moves them out of impulse purchase (or "drunk eBay") territory. And for me, they're kinda in that no mans land of "I want something better that my OPs, do I spend a few hundred bucks on one of those, a few grand on an OP-1, or do I start looking at Behringer clones or 2nd hand pro music studio gear?"

If only the users contributing chord charts to sites like Ultimate Guitar understood this; the number of times I've seen this wrong is astounding. For example, a progression like I-iii-IV in the key of E major will be written as E-Abmin-A but ought to be E-G#min-A for the reason you stated: pratically it's confusing, theoretically it's wrong, and there's simply no upside at all.

Using exclusively sharps (or flats, but that's not so common) is for piano technicians, frequency-to-note calculators, and similar utilitarian situations that aren't in a diatonic context.

Aside: this is also an easy way to explain double sharps and double flats. If you stumble upon one, and decide to see what would happen if you eliminate it in favor of an enharmonic equivalent (i.e., a natural), you'd end up with a scale that uses some letter twice and also skips a letter. The double sharp/flat achieves the use of each letter exactly once. A bit cumbersome on most instruments (keyed instruments especially), but it does make for easier sight reading (vocals especially) when stepwise movement uses each line/space of the staff, rather than skipping.

Reminds me of the z-cam e1, an old kickstarter 4k camera that now has a very nice grown up camera line. There's some lovely reverse engineering around the old e1, including some work talking to it's "sbus" peripheral port. https://github.com/imaginevision/Z-Camera-Doc/issues/27

Such a pity that so many systems all end up inventing their own things. Thankfully the z-cam e1 also had a pretty useful decent http / rest interface for a bunch of the basics too.

It just seems like products would do so much better for themselves if they could exhibit & open their books. I remember seeing the jeep hacks (2015) and rather than being terrified and afraid, just being so so so sad there was such an incredible extensive easy to use well-known control system, for all the car, that would be so cool, but had been for-all-times inaccessible and now absolutely certainly with the scare coverage would definitely for sure be lost to us forever.

What we have now is nothing compared to what would happen. We expect large scale displacement and resource wars, but over the course of decades which gives people to adjust.

What you're describing would, by contrast, would kill hundreds of millions of not billions of people in a few years or more realistically, cause extreme levels of violence to undo it.

Indeed, I imagine anyone who actually managed to do such a thing would be violently murdered by the public and their death celebrated for centuries.

I am an adult with ADHD and have never been able to get past the side effects that I have to drugs such as amphetamines and SSRIs. I was prescribed Modafinil for a short period for "Shift Work Disorder" when I worked shift work as a Stationary Engineer and it was glorious in regard to my ADHD symptoms with effectively zero side effects. I wish the US would expand its usage.
Show HN: I developed an IDE tailored for Python developers
by honghaier | 2025-11-18 01:44:56+00:00
I spent five years developing an IDE for Python developers called "PyMe", which can help Python learners visualize software development. The overall usage process is similar to Visual Basic, where drag and drop can create interfaces, and variables or event functions can be bound to controls through the right-click menu. It can also create a large number of access functions through the mouse menu. Finally, when you complete this task, you can directly "run" and see the results. If there are no problems, you can also "publish" and package it as an EXE, or even an APK on Android devices. The main value of PyMe is to provide Python developers with a WYSIWYG development tool. I fix bugs and update versions every night, and currently only the Windows version is available. You can go directly to https://github.com/honghaier-game/PythonIDE-PyMe Download,

Wouldn't you think it is more important what the goal for the other person is? If their goal is to enrich and make both of your lives better, does it matter whether they consicously use social techniques or have natural automatic ability to do so?

It is also autism vs psychopathy. Patrick Bateman is nowhere close to someone autistic trying to learn those socially successful behaviours. Patrick Bateman is a terrible human being not because they are inauthentic, he is a terrible human being because of the acts he did and wanted to do.

I like your description.

I think sometimes this is when we find our way to the middle of two relatively simple drives: "be an orthodox group member/ avoid being a social outcast" and "avoid the discomfort of cognitive dissonance / admitting hypocrisy".

If there aren't immediate consequences for inaction (especially if there ARE costs and/or social consequences for action) were very good at convincing ourselves to ignore it (or tell ourselves we will EVENTUALLY deal with it but just not right now)

Most of the performance penalty for the languages you mentioned is because they're dynamically typed and interpreted. The GC is a much smaller slice of the performance pie.

In native-compiled languages (Nim, D, etc), the penalty for GC can be astoundingly low. With a reference counting GC, you're essentially emulating "perfect" use of C++ unique_ptr. Nim and D are very much performance-competitive with C++ in more data-oriented scenarios that don't have hard real-time constraints, and that's with D having a stop-the-world mark-and-sweep GC.

The issue then becomes compatibility with other binary interfaces, especially C and C++ libraries.

It wouldn't be just a humanitarian crisis but huge economical and social problem as well - suddenly this single country would be enlarged by ~26mln people who would need to be adjusted to life in a completely different reality, and who also would need to be secured in variety of ways.

The comparison to German unification that's often bring up seems to be accurate only on the surface. There are large differences like mainly the cult of personality created by the Kim family that affects life of people in NK. It's not possible to dismantle that day by day, and surely government which would had to deal with unification would also face resistance to some degree. This society has been for over 70 years conditioned to hate, looking for the causes of their own misfortune outside in the pure evil that USA in their eyes is and its puppet state of SK.

It won't be a 0-1 change where on Monday you attend annual parade where you worship Eternal President and Dear Leader, and by Tuesday you plan your first vacations on Jeju island.

Moreover, the situation in the end of 80s in Europe is the key factor - namely the domino effect started in Poland which spread across the whole eastern bloc. There was a strong opposition building up within societies of Central-Eastern Europe demanding changes and freedom. Pretty sure that's nearly non existent in NK - there's no trigger for large changes. Even the famine in the mid-90s wasn't enough.

I feel both unfortunate and lucky to have grown up in a subsidized housing development. In school I was always seen as the poor kid from that "sketchy area", but as a child, this place was a haven for unplanned adventures and low friction hanging outside with friends. All the housing units were surrounded by a large greenspace area full parks, hills, and a community centre where they ran morning breakfast programs and afterschool clubs.

I have countless childhood memories growing up there. All I had to do was step outside and some fun adventure was going to happen among the kids in the area. As online gaming started to become more popular, the area got much quieter. Not sure what it's like now that there's an abundance of online distraction. I do see the social value in online spaces like VR chat though.
