I installed mini splits (small heat pumps) in each of our rooms. Everyone gets their own temperature and they were only 800$ a piece. Did installation myself and it was pretty easy. Hardest thing was pulling a vacuum in the lines before releasing the freon (or whatever it's called) but all I did was watch a youtube video. They've been going strong for several years. I looked at the prices and they are still the same.

You are absolutely right - blocklisting is a game of whack-a-mole. However, in the context of serialized ML weights, the "allowlist" of valid imports is actually quite small (mostly torch.nn, collections, numpy). Right now, we are flagging the obvious low-hanging fruit (script kiddie RCE) because generic SCA tools miss even that. The roadmap includes moving to a strict "Allowlist" mode where we flag any global import that isn't a known mathematical library. That’s much safer than trying to list every dangerous function

This argument assumes that you only need to radiate away the energy that the solar actively turns into electricity, but you also need to dissipate all the excess heat that wasn’t converted. The solar bolometric flux at the earth is 1300 w/m2, or 2600 for 2 sq m. That works out to an efficiency of ~20% for your home solar, and your assumed value of 750 w yields an efficiency of ~30%, which is reasonable for space-rated solar. But assuming an overall albedo of ~5% that means that you were only accounting for a third of the total energy that needs to be radiated.

Put another way, 2 sq m intercepts 2600 w of solar power but only radiates ~1700 w at 350 k, which means it needs to be run at a higher temperature of nearly 125 celsius to achieve equilibrium.

> One thing I've noticed - artists view their own job as more valuable, more sacred, more important than virtually any other person's job.

> They canonize themselves, and then act all shocked and offended when the rest of the world doesn't share their belief.

You could've written this about software engineers and tech workers.

> Obviously the existence of AI is valuable enough to pay the cost of offsetting a few artists' jobs, it's not even a question to us

No, it's not obvious at all. Current AI models have made it 100x easier to spread disinformation, sow discord, and undermine worker rights. These have more value to me than being able to more efficiently Add Shareholder Value

There is now an even easier way than vacuuming. Instead of pulling the unwanted air and moisture from the lines, you can push it out with another gas, which itself can somehow coexist with the refrigerant. I haven't tried it because I already have the pump and gauges, but if I were installing my first mini split, I'd consider it.

Shorts are everywhere because it is the most addictive form of media, easy to consume, no effort required to follow through.

More generally I think the problems we got into were inevitable. They are the result of platforms optimizing for their own interests at the expense of both creatives and users, and that is what any company would do.

All the platforms enshittified, they exploit their users first, by ranking addictive content higher, then they also influence creatives by making it clear only those who fit the Algorithm will see top rankings. This happens on Google, YT, Meta, Amazon, Play Store, App Store - it's everywhere. The ranking algorithm is "prompting" humans to make slop. Creatives also optimize for their self interest and spam the platforms.

> The rest of the satellite must be within the shade of the solar panel,

Problem is with solar panels themselves. When you get 1.3kW of energy per square meter and use 325w of that for electricity (25% efficiency) that means you have to get rid of almost 1kW of energy for each meter of your panel. You can do it radiatively with back surface of panels, but your panels might reach equilibrium at over 120°C, which means they stop actually producing energy. If you want to do it purely radiatively, you would need to increase temperature of some surface pointing away from sun to much more than 120°C and pump heat from your panels with some heatpump.

>I will eat my hat if Google had nothing to do with the demise of Mozilla

One has to be truly naive to think they get half a bi a year from Google "just because." They have less than 5% of desktop market share and ZERO mobile presence.

IMHO, they wouldn't get this kind of money if they had a competent, technical C-suite that actually cared about creating a truly competitive free browser. The money is flowing because, not in spite of, the current C-suite.

Yea… you can actually fit two adult-sized road bicycles, without removing the wheels or disassembling them in any way, in the back of an F-150 cab!

And still have more room for stuff in the back of the cab before you even start talking about the bed.

I’m also confused how groceries in the bed would get wet in the rain… everyone around me has a tonneau on the bed. My guess is that some of these are not real anecdotes.
Show HN: Sports Database as SMS linking experiment
by garywgrimes | 2025-12-16 17:22:10+00:00
I made a sports matchup database with a UI sitting on top as a learning experiment using native SMS capabilities for "network distribution." No real money changes hands, no picks for sale, virtually no user tracking -- just a database with a UI that generates dynamic SMS links. Been kicking around the idea for over 10 years and stuck on the DB part till recently. I'm curious whether it's possible to build and support something like this on a low operating budget and without hard-to-justify subscription models and predatory user event tracking/re-engagement strategies. I’d love honest feedback on what feels useful, misleading or unnecessary, or what could make it more compelling.

Perhaps because I'm still on Debian 12 (or more likely I did something wrong), I had trouble getting it working by compiling the icl/ocicl sources with sbcl. It complained "Failed to connect to Slynk after 10 seconds". I tried running a Slynk server in sbcl, but icl froze up, and the server said "slynk:close-connection: end of file on #<dynamic-extent STRING-INPUT-STREAM (unavailable) from "#A">. Then I tried running a swank server, and got the icl prompt (good), but then tab completion invoked the debugger: "Package SLYNK does not exist". Finally, I ran the swank server after first running "(asdf:load-system :slynk)" and everything seems to work.

One thing I immediately miss (that rlwrap provides) are the keyboard functions such as reverse-search-history (usually mapped to C-r) and history-search-backward (have this mapped to M-p). History recall only seems possible with the up arrow.

Also, be in for some surprises if you try to paste some lisp code into the REPL, especially if there are long lines. The interaction is apparently meant for a human typing, not pasting.

I'm not personally offended by the inaccurate terms, more just stating what should be fairly obvious. Using accurate terms is very important in logic and reasoning, and being generally polite and respectful is also an important part of good-faith argument and debate when the goal is learning. You not being able to use correct and accurate terms is partly why your arguments are weak and inconsistent. I've explained your logic errors in multiple previous comments. If you're interested in learning more, I've linked several of my references as well. I do agree that there's little else to talk about and we're rehashing the same arguments. You saying that you don't personally consider it offensive and suggesting that therefore it's fine for you to use the inaccurate term suggests that this isn't a good-faith debate for the benefit of learning.

I will also say that it's a common pattern for people to try to justify bigotry with "science," not realizing that their arguments don't make sense. Karl Popper is actually considered the father of modern science for his work on falsification being one of the main ways to separate actual science from pseudoscience. This has come up several times lately and I'm very curious about it.

I have read several books in multiple areas of biology. I'm a little amused you're recommending them to me, when I literally linked and referenced one of the books in a previous comment. I hope you actually read more as well. Biology is an amazing field, which is why I studied it in university. I hope you learn more about science in general. I will also mention, however, that reading all the biology books in the world won't help if there's a fundamental misunderstanding in what science actually is and how to differentiate it from pseudoscience.

Statistical Rethinking (all editions) is a great book if you're interested in how models work and how science actually works, as a personal recommendation. The author also has multiple lectures recorded on github and other platforms, such as youtube. Carl Sagan also has an excellent book on distinguishing science from pseudoscience: "The Demon Haunted World - Science as a Candle in the Dark."

I think this is a lot different than a lot of wedge issues that tend to affect people mostly in theory. Wedge issues are often chosen by the political elite because there isn’t a risk of the dog catching the car effect becoming a major political liability.

E.g., overturning roe v wade made a bunch of republican evangelical republican voters grey happy while restricting the lives of a relatively small amount of people. And I know this statement sounds crazy but hear me out and do the math: You have to be a woman (~50% probability), get an abortion (~25% of women in their lifetime) and reside in a state that restricts abortion (about 20% of the population). Multiply those together and you end up with a 2.5% probability that overturning roe v wade has a tangible impact on your life.

You can apply this same concept to a lot of today’s hot button topics.

In contrast, 1/3 of all adults use TikTok. About 60% of people under 30 use it.

Like I said in my other comments, this is comparable to a government shutting down the NFL. It would be a major optics disaster to implement a TikTok ban.

>It's the IE of the 21st century

I see this claim often. As someone who learned web dev during the days of IE dominance, I don't understand it.

Internet Explorer never kept up, especially after IE6 reigned supreme. They weren't "a little behind" or didn't have some more niche APIs missing or implemented in a buggy or proprietary way. It actively ignored standards, it didn't receive real updates for a long time (IE11 being the fruition of what the best they could offer was) and generally with few exceptions (namely, the invention of CSS Grid and XMLHttpRequest) generally degraded the ecosystem for over a decade. It actively held back companies from adopting new web standards. Its why polyfilling became as proliferated as it is now.

Safari / WebKit has not induced any of this. Yes, sometimes Safari lags behind in ways that are frustrating. Yes, sometimes Apple refuses to implement an entire API for political rather than technical reasons (see the FileSystem API), but largely it has managed to stay up to date with standards in a reasonable time frame.

While their missing or subset implemented APIs can feel really frustrating, they haven't actively held back any work nor the mass adoption of newer browser APIs.

Apple has their faults, but this isn't even close to the drudgery that was the IE heyday era.

I hear you, that's not a problem of AI but a problem of copyright and other stuff. I suppose they'd enrage if an artist replicated their art too closely, rightly or wrongly. Isn't it flattery that your art is literally copied millions of times? I guess not when it doesn't pay you, which is a separate issue than AI in my opinion. Theoretically we can have worse that's only trained on public domain that'd have addressed that concern.

Just like you cannot put piracy into the bag in terms of movies, tv shows you cannot put AI into the bag it came from. Bottom line, this is happening (more like happened) now let's think about what that means and find a way forward.

Prime example is voice acting, I hear why voice actors are mad, if someone can steal your voice. But why not work on legal framework to sell your voice for royalties or whatever. I mean if we can get that lovely voice of yours without you spending your weeks, and still compensated fairly for it, I don't see how this is a problem. -and I know this is already happening, as it should.

Ideally, CI/CD Pipeline (Pre-Merge) - We recently released a GitHub Action for this exact workflow. The goal is to block a Pull Request if a developer tries to merge a .pt file that contains CRITICAL risk opcodes. If you wait until Runtime to check, you’ve likely already unpickled the file to inspect it, which means you’re already pwnd. This needs to happen at the artifact ingestion stage (before it touches your production cluster).

That's how the maths works though. If you are a farmer in Africa you buy one scythe for 10 dollars and your productivity increases by 100%

If you are a farmer in Denmark you buy the second tractor and your productity increases by 20%.

Also nothing was planned.

If rhis was planned then USA losing and China winning was planned too. Just globalization meaning everyone goes towards optimum

Level 1 and 2 charging are something of an equivalent to siphoning gas, and maybe too easily overlooked. Carry a wall plug and dryer plug adapter and you can plug in just about anywhere. RV plug in the camping area of a national park. Utility plug on the back of a work shed in the middle of nowhere.

Won't charge you fast, sure, but can be the difference to charge you enough to make it to the next stop, in some cases.

From Allen AI's Discord:

*Introducing Molmo 2* : State-of-the-art video understanding, pointing, and tracking

Last year, Molmo helped push image understanding forward with pointing—grounded answers you can verify. Now, *Molmo 2 *brings those capabilities to video—so the model doesn’t just answer questions, it can show you where & when something is happening.

On major industry benchmarks, Molmo 2 *surpasses most open multimodal models* and even *rivals closed peers* like Gemini 3 Pro and Claude Sonnet 4.5.

Molmo 2 returns pixel coordinates + timestamps over videos and coordinates over images, enabling: *◘ Video + image QA ◘ Counting-by-pointing ◘ Dense captioning ◘ Artifact detection ◘ Subtitle-aware analysis …and more!*

Three variants depending on your needs: *Molmo 2 (8B)*: Qwen 3 backbone, best overall performance *Molmo 2 (4B)*: Qwen 3 backbone, fast + efficient *Molmo 2-O (7B)*: Olmo backbone, fully open model flow

Demos: *Counting objects & actions* (“How many times does the ball hit the ground?”)—returns the count plus space–time pointers for each event: https://www.youtube.com/watch?v=fvYfPTTTZ_w *Ask-it-anything long-video QA* (“Why does the player change strategy here?”)—points to the moments supporting the answer: https://www.youtube.com/watch?v=Ej3Hb3kRiac *Object tracking* (“Follow the red race car.”)—tracks it across frames with coordinates over time: https://www.youtube.com/watch?v=uot140v_h08

We’ve also *significantly upgraded the Ai2 Playground* You can now upload a video or multiple images to try summarization, tracking, and counting—while seeing exactly where the model is looking.

All empirical evidence shows that single payer systems work better, producing far better outcomes at lower cost, than the US system. In fact, so much better that a single payer system is what Congress has chosen for itself!

But seems some prefer to believe a theoretical argument with no evidence to back it up.

We did buy Uranium from Russia because it was cheap, but they are far from the only suppliers. Half the world can mine uranium: https://en.wikipedia.org/wiki/List_of_countries_by_uranium_r...

Even Germany had Uranium mines in the Erzgebirge. They just were closed due to environmental concerns and the iron curtain falling, which is also why there are no more "official" reserves. There was no exploration done after 1990, so known exploitable reserves in Germany are low. But that's just because nobody went looking.

Uranium isn't rare and it isn't really expensive. We just need so little of it that there are not a lot of running mines.

You can use it for either predictive or explanatory purposes. In the early ('00s) years of Google it was common to diagram out the incentives of all the market participants; this led to such innovations like the use of the second-price VCG auction [1] for ad sales that now make over a third of a trillion dollars per year.

Thank you, I'm glad it's gathered some interest!

I don't have any background as an analyst or anything like that. ACH is a real tool, really used by the CIA, and the existing versions are basically crappy spreadsheets, or not free, or both.

I don't doubt someone with coding skills could do it better, it's just that no one else has stepped up. Probably because there's no profit angle, but that's conjecture on my part.

Imagine the justified backlash if Biden had described the 2024 attempted assassinations of Trump as caused by "Biden derangement syndrome", or if anyone had described the assassination of Charlie Kirk as caused by "censorship derangement syndrome".

When a politically powerful figure says irresponsible and irrational things so openly without a hint of remorse, how much trust can I place in the seemingly responsible ideas that the figure might say on better days? I think Gell-Mann amnesia [1] applies to listeners of influential figures as much as it applies to readers/listeners of media organizations, if not more so.

From what I have seen, I believe that both types of aircrafts are controlled by the same ATC. Otherwise, the two ATCs will have to coordinate among themselves to create non intersecting vectors for each aircraft - which sounds needlessly tedious. But the military does have its own ATCs in many areas. They usually separate the airspace into 'civilian corridors' and 'military corridors', each under the control of the respective ATCs. In conflict zones though, the military operates entirely under their own control. The concept of ATC becomes a bit blurred here. The aircrafts are vectored either by ship-based controllers or more frequently by AEW&CS aircrafts. This is what I assume was happening with the tanker in the story. They were near Venezuela and the Curacao ATC had no information about the tanker.

Not OP, but I automate collecting public meeting data from various local agencies across the US. The below resources might be helpful. Public meeting video can be captured using yt-dlp (and if not made public, obtained with a FOIA request), archived, transcribed, etc. Sometimes there is an RSS feed, otherwise use an LLM provider as an extractor engine against the target datastore.

I don't think everyone agrees that being gay is not a choice. There are no outward physical indicators of a person's sexual orientation. It's entirely behavorial and therefore plausibly under the conscious control of the person. Now, I would agree that a person doesn't choose which gender he is attracted to, but it not something than anyone else can see and immediately understand as an inborn characteristic.

Clearly being black, or hispanic, or asian, or white are physical characteristics. Far fewer people would argue that there is any element of choice in that.

Piggybacking also to say that I hope you succeed, as your work aligns closely with the type of runtime that I had hoped to write someday when I first used MATLAB in the early 2000s (now mostly GNU Octave for small hobby projects).

The loop fusion idea sounds amazing. Another point of friction which I ran into is that MATLAB uses 1-based offsets instead of 0-based offsets for matrices/arrays, which can make porting code examples from other languages tricky. I wish there was a way to specify the offset base with something like a C #define or compiler directive. Or a way to rewrite code in-place to use the other base, a bit like running Go's gofmt to format code. Apologies if something like this exists and I'm just too out of the loop.

I'd like to point out one last thing, which is that working at the fringe outside of corporate sponsorship causes good ideas to take 10 or 20 years to mature. We all suffer poor tooling because the people that win the internet lottery pull up the ladder behind them.

is anyone calling it that? to me, "pickle bomb" would imply abusing compression or serialization for a resource-exhaustion attack, a la zipbombs.

"pickle bomb", the way you're using it, doesn't seem like a useful terminology -- pickles are just (potentially malicious) executables.

It's not corps only though, AI at this point include many open models, and we'll have more of it as we go if needed. Just like how the original hacker culture was born, we have the open source movements, AI will follow it.

When LLMs first gotten of, people were talking about how governments will control them, but anyone who knows the history of personal computing and hacker culture knew that's not the way things go in this world.

Do I enjoy corpos making money off of anyone's work, including obvious things like literally pirating books and training their models (Meta), absolutely not. However you are blaming the wrong thing in here, it's not technology's fault it's how governments are always corrupted and side with money instead of their people. We should be lashing out to them not each other, not the people who use AI and certainly not the people who innovate and build it.
