Fedora and Debian (stable) are not really directly comparable, they have different goals. Fedora is essentially a beta channel for RedHat, equivalent to Debian Unstable/testing. Fedora will ship a more up-to-date desktop, but Debian wi

I had always assumed it was because they had exposed far too many internals over the years, making a JIT that was backwards compatible with the majority of existing code, an extremely difficult undertaking.

My work laptop, a Lenovo X1 running Windows 10, was completely busted out of the box. Sleep doesn't work, massive throttling issues running zoom (only improved a bit with firmware updates), WSL 100% CPU bugs, display port MST bugs, the

Yes, but they've made the convenient lightweight syntax not bounds check. Defaults matter in languages. Other languages make you use an esoteric function e.g at_unsafe to skip bounds checking.

OCaml 5 essentially has it, as "effect handlers". It's how lightweight concurrency is implementated.

Whether or not one thinks C++ is a "good" language, I always thought that (original) Minecraft busted the myth that blockbuster games had to be written in C++.

I had a power button fail on an S21, only a few places were willing to quote and the cost to replace was over £300, more than the phone was worth. I now use the always on screen, so I can unlock without the power button, hopefully prolongin

As if the colour mattered at all! The phones are so slippery and fragile, one is pretty much forced to wrap them permanently in a case.

8088 did not have a barrel shifter, so multi-bit shifts would have been expensive and non-interruptible over multiple clocks. Perhaps game devs just avoided them out of habit.

Functional programming is basically maths, it solves the problem of how to compose software safely. I struggle to understand why anyone who really cares about their craft would not want this. In fact, many want it so badly they are willing

There's nothing baloney about SSA form. I'm sorry to say it, but C is just not close to the metal any more. Even if you are able to hand optimise something so it works well on one architecture, it likely won't be optimal for

This is like saying "the benefits of functional programming are overstated". If you are happy with mutable collections, you've happy with mutable variables, pervasive side effects and essentially the status quo. Many of us ar

We should build compilers that insert these checks for us (if they cannot statically determine them unnecessary). The ability to omit these checks doesn't IMHO justify undefined behaviour.
108.
by grumpyprole 2y ago
It's painful for the compiler too, it has to turn the parents imperative code into SSA (essentially A-normal form) so it can optimise it!

I'm sorry I still don't buy it. Can you please show me a use case where ignoring null pointer or overflow checks makes your product non-viable or uncompetitive? Some of these checks could be removed by languages with better compil

This is of course a popular opinion and pretty much the C++ philosophy. Unfortunately a lot of the benefits of functional programming cannot be fully realised unless you are "all in". The paper "The Curse of the Excluded Midd

Well done to the author on this project. A beautiful architecture and code base with not an "object" in sight. Projects such as this demonstrate how complex interactive applications can be built without pervasive mutable state. Pu

Well investors tend to care more about future growth potential than past performance. History tells us that the outlook for expensive proprietary platforms is usually not so good.

I do. But Apple has a problem if their position is the same as yours.

Nice if you can afford it! With Apple's current prices, most of us don't have that luxury.

I don't disagree that Java has cruft, but Go didn't fix data races, nulls or lack of sum types. It's not a "fun" language for me.

I do wonder whether these apps are using any of the hardware acceleration available in our hardware. These days PCs are second class to mobile phones.

Spot on. An iPad won't last long enough to become some omes beloved object.

Yep, or C doesn't need arrays just use pointers! And C doesn't need strings, just use a pointer to the first byte and assume it's ASCII!

Unlike the PC industry, Apple is/was able to move their entire ecosystem to a completely different architecture, essentially one developed exactly for low power use. Windows on ARM efforts will for the foreseeable future be plagued by
