You can specify the capacity on creation: Vec::with_capacity(foo)

There are also alternative vector like types for different use cases, and you can roll your own.

I really enjoy some of the optimization details like when the memory overhead of Option<> can be elided completely. Other languages with Options will actually toss data up on the heap that doesn't need to be because it is in a Option and, or at the very least always take up a byte with the tag.

Details like this let you use the safer and more ergonomic solutions by default rather than having to worry if they are worth the overhead.

This depends on what one thinks of as build quality. If it is a certain way things look and feels that evoke emotions of quality and power, then yes, Apple's build quality is better.

But if you appreciate that things are engineered in a way to make repair-ability and upgrade-ability easy to make your life better and have less hassle, perhaps the Framework has better build quality.

32 is thin only if you have highly specialized workload. Its enough for all games and even pretty hardcore software development.

yes, but throughput is rarely a bottleneck for consumer grade cpus. Maybe on the 16 core ryzens you could get some benefit for select workloads

I don't think Go's documentation is better than Rust, Go is just a lot simpler than Rust. Especially if you are a programmer with a background in any of the C-ish syntax languages (C,C++, javascript, Java, C#, etc), its just really easy to pick up.

Rust is a mind bending ordeal by comparison with both the borrow checker and other foreign ideas that take a while to come to terms with.

driving a non plug in hybrid to maximize electric use is not the goal, the goal is to minimize fuel use. The former is at odds with the latter.

gameswithgo — Sat, 21 May 2022 12:19:30 +0000

harshness of aluminum is mostly mythological and based on design of some early aluminum frames due to them being noisy. also 99.9% of compliance comes from tires. people reliably fail to detect frame differences in blind studies as well. even people who are professionals and people who insist the difference is obvious.

Since the 1950s battery energy density has improved by orders of magnitude, it has been happening and is still happening. Hasn’t stopped these incessant cynical takes though.

In part the optimum algorithm changes as hardware changes. In the 1980s for instance the CPU was about as fast as a ram access. Today the CPU is on the order of 200 times quicker than a RAM access, which means algorithms need to be designed to work well with CPU caches to perform well. There is also much MORE memory available, so in some cases it makes much more sense now to consume more memory to get more speed. Computers often have many cores now as well, also changing the equation at times.

When our kids were little it was something I worried about a lot because I can absolutely imagine myself doing it. I would never support punishing a parent further because of an accident. There but for random chance goes any of us. (or at least many)

Framework laptop. I think the concerns about it being beta are unfounded, the few quirks it has are also had by Lenovo/Dell etc but you don’t have a discerning userbase talking about a single model so much.

The cynicism for battery teach research is misplaced. In our lifetimes we have seen real enormous strides in battery technology actually go into production. LFP batteries are now in actual Teslas, provider a cheaper/safer/simpler option for lower range cars that depend on fewer exotic materials/mining. Sodium batteries are in the pipeline. Sulfur batteries may or may not make it too.

New comment by gameswithgo in "Bevy 0.7: data oriented game engine built in Rust"

gameswithgo — Fri, 15 Apr 2022 19:17:25 +0000

In general in Rust game engine culture right now there is a strong trend towards using entity component system based design. Sometimes this is a definite good thing, for certain kinds of games it can have benefits both for performance and coding niceness. Entity component systems also play nicely with Rust's borrow checker.

But, in my half educated opinion, it creates a massive amount of unnecessary complexity for many types of games. If you are making something pretty basic like pong/pac man/ simple 2d rpgs, etc, you just have all this infrastructure and all these new paradigms when all you wanted was a way to efficiently load and draw sprites and play sounds.

New comment by gameswithgo in "NASA will test SpinLaunch's ability to fling satellites into orbit"

gameswithgo — Thu, 14 Apr 2022 19:17:09 +0000

To temper your enthusiasm some:

They cannot fling things to orbit, they can fling things very fast but a (smaller) rocket is still needed to finish getting to orbit.

and G Forces are extreme so this is only suitable for payloads that don't mind extreme G forces.
