“the system, or public safety, cares more about the city, now that there’s gentrification and you’ve got big businesses and you’ve got dollars and you’ve got white people moving in,” Clarke said. "White people"? That's racial

Can you prove that binaries compiled with profile feedback are slower? No, I did not keep track of JIT but it is a very raw wound or I wouldn't have commented. I want machine code executables. No JIT. Not even in the theoretical case w

Just in time compilation is still slower overall because you incur the assembler penalty. Another problem with just in time compilation is that one cannot control when and how many times it happens. I'm sick and tired of waiting for JI

The machine code has to be faster because the intermediate to machine code step, which impacts performance at least once is eliminated.

The abstract machine in C is a concept, not an actual machine. The entire C compiler toolchain is designed to translate that abstract machine into machine code suitable for the target.

"Abstract machines and just-in-time compilers make languages like Java more efficient, not less." More efficient when compared to itself, but still extremely slow and inefficient compared to a straight machine code binary executab

That is theoretically impossible: a bytecode VM must perform machine code generation and it must do so on the fly or pre-assemble the code, both of which impose a tremendous performance penalty. That's why Java is so slow, for example.

I think the two-pass assembler method is the way to go. With hand-crafted keyword to mnemonic translation tables.

"So much so that you might as well emit machine code instead." Exactly, thank you!!! So why the hell would you screw around with bytecode!?!?! I don't want portability, my source code is portability! I want the fastest possib

What does owning all these processors have to do with bytecodes and VM's? What kind of a statement is that?

I know that. It's been that way for years. His lecturing was really upsetting.

I sure hope it says something about me. And just for the record, IT is this terrible cesspit of reinvented wheels by hordes, so yeah, hordes are not right. Never will be.

I read that. Outlined means how one might go about it, but doesn't provide details. That's why it's an outline. Why spend the entire book on tokenization circa 1981 when what's really needed are compact, fast, executable

Started reading the sample text but as soon as I read abstract machine it was all over: we have suffered far too much and far too long under inefficiencies and distribution nightmares of abstract machines like that of Java, .NET or Python

It's a popular thing to downvote me, but that's the history of the entire mankind, to punish those who ask the critical questions or think differently from the mainstream. I don't really care any more: if I want to ask my que

That is not what I asked. I asked how well this new terminal emulates DEC VT-family of terminals.

What's the compatibility with DEC VT family (100, 220, 300, 400) like, id est can this program be used to ssh into a UNIX®️ host and do work as one would for example with PuTTY?

You should not need to build static libraries if you pick the oldest RHEL you can find among your customers: the GNU people claim that their libc is backwards-compatible, so your executables and libraries should work with the latest glibc.

by Annatar 7y ago
Don't do it. Customers hate it when you don't deliver clean operating system packages for the platform they run and they consider anything less unprofessional. I'm talking about enterprises and governmental institutions, not

I do, because in long term sight their approach is irrational and expensive.

A language package manager is system administrator's enemy and her or his nightmare. Now you explain to me why and how that is the case.
472.
by Annatar 7y ago
Absolutely correct. Those who do not understand the hardware on the register and machine code level should go master that first before dabbling with C. One has to learn to walk before one attempts to run. Working on and with computers requi

That's again due to incompetence and not a fault of RPM. My own spec files build cleanly across both without any additional effort. It's not rocket science but insight.

Search for "free shell accounts". You might be surprised.

But you don't have limited time to re-invent the wheel over and over again by inventing new programming languages, learning new frameworks and re-implementing what already exists? How many headlines here were of the "why do it ine

What do you think powers the InterNet that you're connected to right now? Multiuser systems, running applications under different logins. Even the much hated systemd brought physical multiuser computing back to GNU/Linux.

Linux is just a kernel, so every distribution is a somewhat similar yet completely different operating system. Reality is, most software targets CentOS / RHEL, OpenSUSE / SLES and Debian / Ubuntu. That's exactly two pack

But it won't solve the problem of developers' unwillingness to learn how to make operating system packages now will it? I don't get it: people like that will sink and waste hundreds of hours learning useless garbage like Pupp

"No need to install". This is every system administrator's nightmare: users running arbitrary executables bypassing operating system packaging. Come time to upgrade or reinstall what can happen? If there are security updates

I know, I run NetBSD on my A1200 as well. I have it set up as a dual boot.
