The style guide always uses (( so the operators are numerical comparison. See also where it says: > For preference, don’t use [[ … ]] at all for numeric comparisons, use (( … )) instead.

That's interesting that Ruby is as slow as it is, the regex engine (Onigmo) is written in C. I wonder where the bottleneck is compared to the other languages.

Do you mean generics? Go has had reflection for a long time.

In my experience it's usually JVM at these companies, not specifically Java, and certainly in recent years more and more teams use Kotlin for backend services.

Windows has had this enabled by default for a long time: https://docs.microsoft.com/en-us/windows/win32/memory/data-e... There's a per program exception list to handle legacy programs though.

Which part of the JVM is complicated by generics? They're type erased so the VM shouldn't really care. The compiler on the other hand has plenty of complexity...

by esprehn 5y ago
FWIW Java doesn't sacrifice compiler speed for generics, they're entirely erased at compile time which is cheap. What they sacrificed was runtime correctness, because the type erasure lets you sneak invalid types into unsuspecting

It would be great if this used the same filter format as sourcegraph and other internal code search tools. ex. -file:.html is enough to filter away files ending in html in the main search box. Having to use dropdowns and multiple input fiel

The deprecated frontend stack they reference would seem to be GWT: https://en.wikipedia.org/wiki/Google_Web_Toolkit So they're rebuilding the app in TypeScript with Angular instead of with Java+GWT.

by esprehn 5y ago
This is not measuring what the author thinks it's measuring in Chrome. The benchmark iterates through 100,000 sequential IDs, and does so 105 times. For getElementById: This is a map lookup every time. For querySelector: Chrome caches

Browsers do exactly the optimization you're describing: https://source.chromium.org/chromium/chromium/src/+/main:thi... Both getElementById and querySelector are quite fast, down to the level of mea

This code should use OptionalLong instead of Optional.of() which doesn't have primitive overloads and caused wrapping of the long into a Long and extra heap indirections. It still probably can't beat Rust, but what's presente

There's overhead to a process that doesn't exist with threads. You can definitely split your work across threads in JS using Workers, ServiceWorkers and the main thread. Most apps don't take advantage of this very well though

For sure hacker news is pretty light weight, but it also seems they didn't feel any pressure to use AMP (and also have historically not cared about SEO).

This doesn't appear to be all that "modern": it doesn't support string_view for lookup without extra allocations, and it doesn't support unordered_map (or even use it as the default) for objects. It seems they'

Do you have real world examples of that though? Nearly every real world news, facts, recipe, cooking blog, etc I can find loads huge amounts of JS. Ex. Here's Snopes: https://www.webpagetest.org/result/210818_BiDcQ
