@holliemaea They also reduce the heat in winter. Typically will have indoor temp target of 19°C in winter and 26°C in summer

It’s funny that Europeans don’t think it is their Moral Duty to not heat their houses in the winter, but cooling their houses in summers is just unacceptable. What is the difference?

@aadityansha_06 Do you know about the align_value attribute as well as restrict? Those help a lot getting auto vectorization to work.

Optimizing 1024 * 1024 matrix multiplication in pure C by just using standard library and so far i have achieved 0.588 sec from 58 sec in naive on my i3 2nd gen processor with dual core and still about to do tiling and prefetching.

@ClintFiore In France, tap water is free in every restaurant (by law). No idea what a gallon of water is though. I would say 2L a day is pretty common. I don't know if you know, but eating healthy food count as water intake. American eat too much fried/grilled/salted food.

Is everyone in Europe dehydrated? Nobody carries water bottles. Water is expensive everywhere and not free at most restaurants. Bathrooms are scarce and often cost money to use. My theory is everyone is ok with this bleak situation because they’re all massively dehydrated, rarely pee, and don’t know the glory of what 1+ gallons of water consumed per day feels like to the human body.

@jonathan_wilke Programming languages still use text. We made graphical programming languages but they never took off, except maybe shader graph. Once the level of abstraction you need is too high, the graphical aspect gets in the way. The terminal allows you to chain and loop commands.

I don't get the hype around CLI coding tools like Claude Code. Human-computer interaction evolved past the terminal 30 years ago for a reason. UIs won. Why are we regressing?

@code_star It's a joke. No French people would name it "fat" that's a dirty English word. Also "chaton" is a baby cat. Wrong naming all around.

we named it random access memory (RAM). then we built three levels of cache, prefetchers, data-oriented design, and an entire performance-engineering discipline whose whole purpose is making sure nobody accesses it randomly.

Came up with a real simple way to make these flasks look like they have liquid! 💦 1. Model glass & invert the normals 2. Model the liquid 3. Rig the liquid with a bone facing up 4. in engine apply "jiggle physics" with negative gravity #gamedev #unity #blender #animation #b3d

@prieurdp If your vehicle has front-wheel steering then your center of rotation is on the back-wheel axis, meaning you do much shaper turns when reverse parking than front parking (that's not symmetrical!). That's why parallel parking needs it, same if the parking space is too tight.

Why do people reverse into parking spaces? At first it was one or two misdirected fools, now it's spreading like a disease. It makes no sense. You are only making it so much harder for yourself, and everyone hates you as you block the road trying to get into the space.

division is 20-40 CPU cycles. multiplication is 4. if you're dividing by the same constant in a loop, you're paying that tax a million times for no reason. one reciprocal. computed once. everything else is multiplication.

@Devon_Eriksen_ Typically, this goes as follow: install A/C (no, there is no issue with it, plenty of options), use it for one month, then see the electric bill, and never turn it on again unless you are dying, complain about the heat.

Dear Europeans: Yes, we understand that central air is hard to build into old homes. Yes, we also understand that your windows are a bit different. But here's the part that confuses us. Why do you have to buy window A/C designed for American windows? Why can't Europeans, living in Europe, design A/C units to fit European windows, for other Europeans, who live in Europe? Yes, Willis Haviland Carrier was an American, but he solved this problem in 1902. You have had over one hundred years to adapt his work to a slightly different aperture. Do you not build things anymore? Are there some regulations preventing you? Will your neighbors just relentlessly shame you for having air conditioning? Seriously, unsarcastically, what the hell is the obstacle, here?
Alyse@mrs_alyse

"Who told the idiot Americans we can't open our windows?" You did. You said your windows don't open to accommodate ac units. Others posted actual regs saying they can't fully open, or bars have to be installed, reno projects are hard to get approved, etc.

@eneri74362847 @Lina_Hoshino His `magic` function's return type is `int` yet there is no return statement. That is undefined behavior, and therefore unreachable. It should print a warning by default though...

I sometimes hate developers. They will make a new file format that has ascii header of unlimited length followed by the binary data AND THEY WILL NOT EVEN CARE to create magic bytes so any text file looking like this is a valid radiance hdr file #?(anything) EXPOSURE= (float value) FORMAT=32-bit_rle_rgbe

@realsaadasad The reason why two stair cases are required is in case one has a fire in it. If you put both staircases that close to each others I'm pretty sure they will both be unusable in the above emergency.

Washington unanimously legalized scissor stairs, a building code reform that frees up to 56% more living space per floor. Less wasted space means cheaper homes on smaller lots. Most US states banned this since the 1970s for no good reason.
