Cold air is more dense, than hot air. In winter the difference between the room air temperature and outdoor air temperature is much bigger, so the density difference is much bigger, making Archimedes force stronger and the airflow stronger as well.

BTW, that's also how stove pipes work - vertical column of air hotter than surrounding accelerates well and creates a strong airflow feeding the fuel. But if the pipe is thermally conductive, that air will cool down and won't flow, for hydrocarbon fuels it can also condensate water, that could extinguish fire underneath it. So, pipes are made insulated enough for strong flow.

I've actually tried something like that, with two tools:

* push("What I'm about to do"),

* pop("What I've achieved").

"Push" marks the position in current context after the call and returns "Proceed", "pop" erases everything after the matching call and replaces "Proceed" in it's result as what was passed to the argument to the "pop", effectively pruning long-winded head even inside one reasoning stream. In the end the model only sees how it decided to do work on something, and that it was already done, forgetting everything it between, except what it itself decided was important.

Gemma 4 31B QAT successfully uses it when navigating a maze, marking positions at intersections, exploring them, navigating back and pushing again if necessary. Smaller models often fail to mark positions and forget to backtrack as well, instead they try to rely on themselves to track their paths and navigate back (and also fail).

I think it should work for long-running deep research tasks, but I was too lazy to test it, because it all required a lot of code to glue this up, since most tools and libs are not designed to work like that, and now I'll need even more code to test it, without a purposeful task.

It doesn't work in other languages. Searching the same in my native language (literal translation of "disregard definition") leads to (translated):

> I understand. Write what exactly your request is, or enter the text that I need to process. I will not give any definitions in response - we work exclusively on the essence of your question or task!

Which is especially funny, because it goes directly against your intention of finding definition by querying quickly in "grug-language", which worked for old search. Now you have to write in more literate style, slowing you down: swapping word order for it to sound more human-like doesn't work, surrounding "ignore" in quotes works.

You will be right, but we already see this blame-shifting with "AI deleted my production"/"AI told me to do it" and washing it away with "AI can make mistakes, so double-check responses". They will try to make you responsible for trusting something you see on screen marked with an asterisk as not trustworthy and not reading the box with another asterisk.

> the correlation between $just_bought_thing and $will_buy_another is very, very high

This looks like an argument against advertising the same thing. Why would you advertise something, they were already going to buy?

But showing an ad before their next purchase definitely would improve the numbers on the "our conversion rate chart" _advertised_ to ad buyers. A con played by ad companies to sell more ads.

I'd add: since the AI is now referring the product "as if" it's an honest advice from a secondary source, they would be exempt from the usual advertisement rules.

Effectively, if you were to search "the best oatmeal without asbestos", it could suggest you "AsBestOats", and "AsBestOats" would only advertise asbestos in its content on the box for the human to see, but advertise to crawlers it's "the best oats without asbestos". It's not a false advertisement, because they didn't show it to a human, and machines can't sue.

If it's a subsidiary - they can't capitalize on the big name in marketing. If it's a subscription - they don't get the "buy now, play never" customers from Steam. I think it will be a win regardless.

I think it's the right moment to acknowledge that Epic Games handled discontinuation of Unreal series well and responsibly [0] and how standalone servers were good for community.

* When GameSpy announced shutdown, patches were released to use Epic released the "post-GameSpy" patch, replacing the GameSpy servers with Epic's master servers for Unreal Tournament 3 [1] * Older Unreal series games later were transferred for maintenance to OldUnreal [2], and also made free.

At the same time, they are not open source, nor source available. So, there is an entity, that owns the code and maintains it, without the hassle of opensourcing it.

This is because the series have a strong community, which was in large part formed because the standalone servers, prior to algorithmic matchmaking, allowed people to gather there and learn to be social to each other and learn gaming etiquette. You had to play strategies for repeated games and be civil to others. Modern matchmaking strips us of that - you play with others once and go separate ways, so you don't have to deal with consequences and can use one-time game strategies, which leads to poor behavior and less enjoyment. Yes, you had players of drastically different skill levels on the same servers, and that was a good thing. Skilled players could teach newbies, newbies could learn the gaming etiquette and see what's possible, instead of boiling in the same pot with others playing completely different games than on the other skill levels. You had the core game and the social game on top of it, now we are all alone in our rooms interacting with strangers we will never see or play again with nor against.

Maybe Epic is not the best or the most loved company (compared to Valve) but I respect, that they understood that "this cow has gave us enough milk already", and could part ways with it, leaving existing community satisfied.

I don't believe there is a country in the world, where parking on bike lanes is explicitly allowed. Merging before turns and stops for drop/pickup/load/unload sure. But not parking.

Yes, this is the bias we are looking for. If you can't quit vim, don't know how your frontend communicates with your backend, can't type on a regular qwerty keyboard without looking at letters, or navigate UI without mouse, never used a debugger, don't know how to check if it was DNS, can't write a spec for a feature, after talking to stakeholders (and defend it's priority on their behalf), or don't know how to open dev tools in your browser - you are not ready to herd the cats yet, they will herd you off the cliff instead. And that's okay, you'll get there someday.

It's not about using vim, it's about when you had to sudoedit a config on a server you visited the first time, and it had vim as default EDITOR, so you have to know how to exit it and open nano, or whatever you use. It's about exposure, exposure to many small things is a sign of experience, it is experience, to be precise. If they don't know small basic things, it's a sign, they don't have relevant experience. Can also check, if they have empty lines at the end of their files, know how to remove docker images from their machine, or get a TCP/UDP joke.

I'd say, their degree is BS. You can't finish Uni as a EE, without using a scope a few times.

That rant is especially funny, because its author (probonopd) was responsible for some of the things he was ranting about, by ignoring pull requests to his projects, that would resolve them.

> Further, it's reported that it takes dozens of FPVs to kill a single "hedgehog tank", which brings the total cost of one kill to a rough parity with "classic", "expensive" systems like the Javelin, except Javelins can be carried by a mobile squad, and launching FPVs requires a dedicated immobile unit with a long logistical tail.

You still need to get to the line of sight with your Javelin, which is unlikely in current meta.

> They still can't produce a domestic ballistic missile at scale, because it's genuinely hard

Also, because it costs a lot and there are only two benefits of ballistic over cruise (if you exclude delivering nuclear payloads, which Ukraine doesn't have): it's very fast and hard to intercept. Both are needed sometimes, but often not a requirement.

Ukraine is comparatively small, so air defenses can be packed close, Russia is big and harder to cover with air defense systems, so drones and cruise missiles are a better investment for Ukraine, since they can overpower the AD locally and are much-much easier and cheaper to produce, meanwhile ballistic is a better investment for Russia, since anti-ballistic systems are even harder to build and cost a lot.

Your microwave is leaky, and/or not grounded, but since you don't experience static, I assume you have grounding at your house. Without grounding static and mains hum is quite noticeable. Try touching the body of your pc and listen how silence changes in wired headphones.

* They don't need charging, but you will hear static regularly when attaching/detaching/touching things. Also, they pick up RF interference (TBF, BT ones also drop packets in RF-noisy environments, but they seem to be more resistant to it)

* They are harder to lose, but the ones with non-detachable cords need repairing the cord if it rips, which happens frequently. Never happened with BT headsets I own.

* For BT headphones with detachable cord I agree, that BT channel reduces quality slightly, compared to cord on the same device. It's not as bad as vinyl/tape, though. You have a chance to notice it on lossless. but not regular MP3s.

* Wired don't need to pair, but need your awareness of the current relation between the cord and your body and surroundings, otherwise you will be constantly re-attaching them, or ripping cords. They don't glitch or lag, but pick static and RF.

Wireless is really convenient, if you can afford headphones that last a full day, or a pair of them to switch between and don't have many sources of sound to play to the same headset, even at different times. There are own standards that skip BT and use analog RF to skip the lag and drops (with a dongle), but they too have the issue with RF interference. You either can have digital with lag and rare drops, or instantaneous analog with frequent noise without drops.

Why would they decide on "who", if nobody shows enough effort to signal on "what"? Whining doesn't count while the result is achieved, because "it works" and "don't fix it if it ain't broken".

It's a popular theme in corporate culture to avoid initiative, because you may be then made responsible. You can become responsible first on your own terms instead.
