Myfitnesspal and and fatsecret (the two most popular apps) are annoying as hell in the same way. They make it very difficult to just add calories because they want you to help fill in their food database. Anyone know of an app that only tra

Yeah it's a bad trade-off developers don't realize they're making sometimes. Spring is Gigantic. Application containers like Tomcat aren't much better. It's easy to write huge apps in Java that still perform well so

It's a damn shame really. MS killed the golden goose by tryiing to squeeze too much money out of it years ago. C# is an excellent langauge, the design and type system are just incredible. But they missed the open source boat by about a

This is actually being addressed, eventually. There's work being done to lower the startup time in Java 9-10 but I'm not sure what state it's in. Basically cache everything from the first run to make future launches almost in

I miss all that from C#, some of it a lot. But Java has a community so large that they've basically hacked these things into Java anyways. LINQ -> streams, QueryDSL, RxJava, JOOQ etc Async/await -> Comsat/Quasar The typ

I came from the C# world :). And yes, it's even more powerful, plus reified generics. The huge problem is that it's not that much better than Java which has ~50X more open source software written for it. The day MS makes a bytecod

The JVM is a double edge sword. It makes all of this possible. Not only can you generate code at runtime, Java will optimize it just as well as if it was originally compiled in the application. I'm not sure why people harp on the JVM s

Java is crufty, but it's the best general purpose language I know. There's hardly anything you can't build in Java. "Casual" Java programmers usually miss the most important feature, what really makes it possible to

I switched back a few months ago on all of my devices and only go back when I need Chrome devtools, Firefox is absolutely back in its prime. Feels just as speedy as Chrome on desktop and mobile, and handles large numbers of tabs better. Iro

Performance and type safety are absolutely linked. The only major reason JS is still 5-10x slower than Java is looseness of types preventing optimizations. The Java community is still vibrant and much larger than Go and Rust put together. M

The frame encoder for AV1 would blow away anything we have now but there isn't a push to use it on images unfortunately. HN tends to dislike abuses of JS but one of the coolest polyfills I've seen tricks browsers into using their

Similar to Quasar then I assume. I'm sure native fibers would be faster, but bytecode is fairly close to ASM and i don't think the performance difference is large. Benchmarks I've seen for Quasar show no performance differenc

Benchmarks game used to have stats for Scala but apparently not anymore. Many of Scalas abstractions, unlike Kotlin, have runtime cost

I appreciate the time obviously spent on this, but i see a couple errors and ommissions. C# and F# are VM languages that run on the CLR which is extremely similar to the JVM. Also, Go and Erlang use fiber blocking threads (userspace threads

Batteries have definitely gotten way cheaper over the years, making them usable despite their marginal energy density in things like cars.

by thermodynthrway 8y ago
Sadly, it isn't remotely that good, closer to a change from C to AA. NiCad rechargeables have been around for over a century and LiPo only has a density about 3x higher. Overall we've only increased the energy density of the avera

Assuming their internal projects are built similar to OSS, I ask you to try playing with them yourself and see if you come to the same opinion. There's better ways to critique an arch than just measuring outages. Netflix has built an a

I'm not surprised. I've tried to get Netflix's OSS tools like Spinnaker running and it's a total nightmare with how many interdependent services need to run. It took me days to get running and was never reliable. I think

I've found the speed of the framework generally matters more than what you do with it for the same reason. The size of the framework often dwarfs any application built with it these days. We have a huge project in Spring Boot that craw

You can use fiber libraries like quasaras your executor, just like Go uses for regular threading. The double edged sword of Java is that you can do anything. But the learning curve is huge because there's so much crap out there

I've messed with async on JVM. In my experience, it doubles speed at most for CRUD apps with heavy DB access. Async is only useful if you're thread starved, and most DB calls are fast enough that it never happens. The one place it

The direction doesn't matter nearly as much as blowing the fan through a large-ish opening. You want the air from the fan to accelerate other air on the way out/in. This is the same principle as turbofan engines, in which a higher
