@tonyszko @levelsio on that note it's pretty wild what difference just 2km makes, I'm on the western side of Poznan, and the winter AQI delta in some directions is 150+

@_ptonik @levelsio OK, so that might be the case. Close to Warsaw with dense neighborhood - filters needs a change once in a month during winter time.

So a few things: only until recently European homes didn't have AC installed, not just no HVAC, barely any AC at all Even now it's very low, about 20% of European homes have AC Our house has AC in every room though, but just to cool, they do nothing for air treatment like removing CO2, setting humidity right, getting in fresh air, etc But no HVAC, no air tubes, no central air, etc, I haven't see any European house that has that, best we have is an air vent in bathrooms that goes to the roof to get humidity out a bit Of course Europeans just open the window, which is great, I live near the ocean, but at night there's noise sadly, barking dogs, garbage trucks at 6am, it goes through ear plugs, I'm not complaining but an HVAC system would fix the CO2 and get fresh air in without the noise And sure in office buildings in Europe but not homes, we don't have air treatment like HVAC, no ducts, nothing!

@tonyszko @levelsio I have a humidifier in my Systemair setup (Condair RS I think?) - steams up the vents if the air gets too dry. on filters tho, spring is surprisingly worse than winter, pollination destroys them. I live in a natura2000 forest area so winter air is pretty pristine.

Nicely integrated. We have opted out from the integration - little benefit (except of those ugly units), adds a bit of a cost and maintenance is a bit different. You can also use it together with heat pump to recover some heat or cool down air a bit (depends on the time). One thing - during the winter in Poland I would change the filters a bit more often than 3 months. Also, in my unit at least, you can use different type of heat exchange unit to keep more humidity inside. The air you get from this is pretty dry. If you need it - that depends on the humidity in your home. In the end - worth every penny. Fresh air whole year, cleaned, 24/7

@parasight @levelsio im overweight but sleeping really well. I think that fresh air + not drinking were the two main factors.

@_ptonik @levelsio Man, this is my dream. Silent sleep and fresh air.

using that logic, farting indoors raises room temp. also technically true, also irrelevant. at 90% recovery the air comes in at near-room temp. cracking a window in a polish winter is a 25°C delta, that's the comparison I was making. you're not wrong, just sort of missing the point.

@_ptonik @levelsio Be honest - that's not "zero heat loss." The heat exchange makes so that air coming in is way warmer than external, but still there's a non-zero difference. Usually it's small, like 4C, but still a bit :) And it works other way around too, so in summer air coming in is colder.

@levelsio "Special NETO glass fabric is used on the inner side of the duct to achieve maximum acoustic absorption and keep noise levels to a minimum." isover-technical-insulation.com/self-supportin… (not associated with the company but very happy with the product)

@levelsio I use sound-proof vents, running the AC through them as well and there's ZERO noise, even with the AC blasting. Looked up the pics and looks like they're called Climaver. Plus it's super easy to bake this into your smart home and home automation openclaw.

@nasqret gratulacje (z Poznania)!

My passion for computer algebra systems and programming has been noticed by OpenAI. I am very proud and humbled to be featured in the main GPT-5.5 premiere. I was one of the members of the ChatGPT Pro community who got early access to this model. I can only say that this model and Codex are now my main research tools for algebra, visuals, coding, editing, literature search, and more. The evolution from the early models to where we are now is enormous. At this point, I can compile almost any library on the web and integrate nearly any piece of code or algorithm I need for my work. This is a major shift, and its consequences for the community of programming mathematicians will be vast. These GPT tools now give me more space for ideation, tinkering, and exploration. I have never explored mathematics more widely or more deeply before. I am also seeing the first glimpses of genuinely helpful insights in my conceptual work. Human + AI - that's the vibe for 2026. It's hard to believe how much progress has happened since November 2022.

@TheDealMakerGuy nothing says "we're leading the AI race" like lawmakers applauding a 2 year old alibaba robot running an llm off an ipad in a backpack through a zip-tied bluetooth speaker

A Polish MP brought a Chinese robot to Parliament this week. Photo ops, excitement, look how techy we are. Meanwhile in Kraków, students beg for money outside city hall to afford a robotics competition trip to the US. G20 economy parading foreign robots but not funding its kids

@hermez042 @jakub_rusiecki oh, so you must be the person trying to game my leaderboard mechanics :>

@_ptonik @jakub_rusiecki hey man, can you have a look bountybook's oracle has a bug in its ipfs fetcher that's crashing before it even looks at my code submission

We (🇵🇱) just passed Switzerland to become the worlds 20th largest economy. 35 years ago GDP per capita was $6730 Today its $55340. I wasn't around when we went capitalist in the early 90s, but you could definitely still feel the grip of communism in the early 2000s. Central Warsaw was in many parts old abandoned ruins. You had to take your radio out of your car every time you parked or it would be gone among anything else you left inside your car. The same city I walked with my mom as an 8 year old is completely unrecognizable now. 38% annual growth since joining the EU in 2004 EU average was 18%. Watching your country transform in a generation is feels incredibly special. Long live capitalism,free markets and honestly long live the EU! If not for the EU we would've been significantly worse off.

small world! ◡̈ plenty of talent, just no ecosystem to let it thrive. ElevenLabs founders are polish, OpenAI's chief scientist is polish. none stayed here and its hard to blame them. buuuut - (might be verging on arrogance) I feel if any country can figure it out in a generation, it's us.

yeah the arbitrage is almost gone. I've been thinking about the exporting talent, but not companies framing a lot and I think it's an even broader problem for Europe vs America although much more painful in CEE. My conclusion is that we as Europeans struggle to sell ourselves as well as US founders. For example take 2 founders building in the same category with basically the same traction. My rule of thumb is a US founder is going to sell it as something incredible and a european founder will be more grounded when pitching which makes raising a lot harder for them. I think these skills are learnable though and I'm always on the lookout to back teams in the region. That being said we see outliers and we're proud investors in @redstone_deti from Poland. btw been hearing great things about Tonik! Would love to chat :)

@jeff_weinstein @tempo @stripe nice - building a marketplace where agents pay other agents for completed work. genuine q: who creates the PaymentIntent when both sides are agents? an agent can spin up a wallet in milliseconds but can't spin up a stripe merchant account. or am i missing something?

@PaulYacoubian uh, spending more on marketing than most of your customers entire annual revenue to sell them a $300/seat tool to schedule linkedin posts that get 4 likes

How to Use Billboards to Close 7 Figure Contracts: "Billboards can be used almost like performance marketing. At Segment, when they wanted to close an enterprise contract, they bought a billboard directly outside the company’s office addressing them specifically. It became one of the cheapest ways to close a six or seven figure contract because every employee saw it." @ElenaVerna Biggest lessons on how to make billboards really work @pedroh96 @awxjack @ZReitano @KyleTibbitts @karimatiyeh

@Julian imagine having abundant, clean energy. hard not to be hyped about the future. wild its happening in just mere months.

in case you're unaware: matt started a company called aalo that's making nuclear reactors to provide unlimited energy. they turn on a reactor THIS YEAR. modern nuclear is almost here. they solve the problems of slow build times and safety. the factory pumps out hundreds per year
