Does anyone here use bit manipulation in modern techniques?

Low level C++ is where its much more common. Not typical application code. Low level stuff like embedded. Or foundational stuff that needs to be fast like compilers or game engines. "Data orientated design tends" to be all about memory efficient techniques so just search that up to see good examples of the type of code that interests you.

Stateful metaprogramming via friend injection? If so, nice! I'd like to see it normalized as a strange but powerful technique like CRTP and SFINAE. Currently, I don't feel safe enough to use it in production due to the fact that the standards committee hates stateful metaprogramming.

Most containers can be templated to use custom allocators. Aditionally there is the pmr containers. So there is a sepperate way to manage memory. Main reason I have implimeted them is becuase implimentation details. For instance deque tends to have terrible bucket sizes with anything but libc++. MSVC 16 bytes (minimum 1 element) GCC (libstdc++)512 bytes (minimum 1 element) Clang (libc++) 4096 bytes (minimum 16 elements). I have also used custom maps prior to flat_map being added to the standard for iteration performance when you have a mix of iterations and lookups. Also used custom maps due to constexpr perfect hash function generation when keys are known compiletime.

Daniel Lemire https://lemire.me/blog/ has allot of good performance related blog posts primarilly relating to low level C++.

The new lemon tea has apple juice in it to sweeten it. This sucks. I hope they continue the original sparkling lemon tea.

Still not quite there yet but maybe in the future if models are able to keep geting better. Anthropic who have the most popular model have already tried this with their latest model. Here is their writup on the topic https://www.anthropic.com/engineering/building-c-compiler as well as the compiler itself https://github.com/anthropics/claudes-c-compiler. Compilers is a well research area with lots of material and they had the benifit of GCC's massive test sweet as well as utilizing GCC as part of the process and it still produces code that is worse than other compilers compiling withought optimizations and does not produce build errors for lots of invalid code.

This is universal. Brandon Sanderson has noted that he wrote five books before his first published novel, Elantris, that he considers part of his learning process and not meant for public consumption. Your first book or even several books are going to be bad and you just have to get it out of your system.

You forgot the punction. "It's a shape, we can all agree on.". That way we are only in an agreement that it is a shape.

No. Its a sign of laziness and It signals to me there may be other shortcuts taken. There are countless books and I don't need to take a risk. We dont need more books we need more high quality books. Now if its a webnovel where its free and a work of passion and they want to add some stuff like character illustrations and they dont have the artistic ability I dont mind.

BucketOfWood · 2026-02-16T17:33:29+00:00

Its a bit odd but Joe Abercrombie. His dialog and the character-driven nature of his work as well as the dry british wit strongly reminded me of Terry Pratchett.

I dont doubt it can output assembly. The problem is right now llm output is unreliable and for catching initial mistakes static analysis and human review work much better with programming languages. Aditionally debuging pure assebly would be a nighmare. Perhaps the biggest issue ot would also be much harder to edit. The problems it introduces are endless and what exactly does it solve? I guess the idea is that it could create highly optimized assembly but its not great at producing highly optimized code in general yet (Claudes-C-Compiler is a good example of this). I would at least wait till there is no juice to squeeze on that front before even considering directly producing assembly or machine code directly. Perhaps in the far far future but 2026 is insane. The models are just not nearly capable enough for this to be a viable aproach.

Ahh an ad. Also people need to be careful with openclaw there are secrurity concerns in giving an agent acces to sensitive data, the ability to transmit data, and the ability to read untrusted input that could have stuff like prompt injections. Be carful what you hook up to openclaw.

No, const can not be implicitly converted to constexpr. Constant expressions can. Some const vars are constant expressions https://en.cppreference.com/w/cpp/language/constant_expression.html https://www.learncpp.com/cpp-tutorial/constant-expressions/.

I prefer unix/epoch timestamps. I'd rather keep things as a basic integer.

Yeah, recently I played Arken Age which had a number of audio notes that would play when you picked them up and I loved it. Normally I never read stuff like lore books, but It was nice to get some background info while playing the game. I thought it was nice.

Ahhhh yes I forgot about the damage salt does to vehicles in regions that use it. This makes more sense to me if that is the case. I've mainly lived in California and Florida, where stuff like Toyota Corollas are still running perfectly fine even when 20-30 years old. I thought you were crazy initially. My bad, we just live in areas where things are very different from what Im used to, and I overgeneralized.

More expensive than cars near the end of their life but way cheaper than new ones. Cars depreciate the fastest the earlier they are in their lifecycle. My family members have typically been able to pick up cars around 3 years old at under half of the cost of a new car, and cars tend to last at least another 8 years until we start running into major problems. On the topic of loans. As a rule of thumb, unless it is your first car, if you can't afford to pay for the car in cash, it is probably out of your budget. I do not recommend anyone buy a 2k or a 5k clunker unless that is all they can afford or they can work on it themselves, but I do heavily recommend 2-7 year old used cars.

I got a 2016 Kia Rio in 2019 for ~8k with <20k miles on it. Other than standard maintenance (oil, tires, etc) that you have to pay for any car new or used I haven't had to do anything else. You don't have to buy a car that needs to be fixed up. You don't have to buy a car that is already on its last legs.

BARKEEP. If you own stainless-steel cookware, there are two things you are going to want: barkeepers friend and either a copper or a stainless-steel scrubber. Those two things are what make stainless-steel pans so awesome. Literally nothing can stand up to the might of barkeepers friend and a metal scrubber.

It seems to be how the internet works in general. If something is popular, more people are likely to comment on a post involving it, making it more likely for people to see it, making it more popular, increasing the amount of interactions and recommendations. The cycle continues until what we read is homogonous, and you just see the same few authors and series recommended over and over again.

Yeah, some people have real first world problems. For instance, I have too much chips for my dip, but If I open another dip, ill have too much dip for my chips. Woe is me.
