I’m sure that was part of the motivation, but it was taught to me as “readers often stop reading after one or two grafs, so put the most important information up front.” It ends up working so that both pressures apply the same way: reverse

For a contrary point of view, I don’t think the Dragon book actually holds up that well. All of the front-end parsing stuff is good, but heavily biased toward LALR parsing, which is rarely used in production compilers these days because it’

I think the only thing I’m assuming here is that there are people who want to do the work. Perhaps because it’s fun to write a compiler (it is!), or because they don’t view llvm as the pinnacle of compiler technology, or maybe their employe

I’m stunned that this article exists and was published by Microsoft. Unsafe access to either is clearly undefined behavior. Discussing which one is more or less undefined is like discussing whether it’s safer to run with scissors or a knife

Unfortunately tsan is a pretty big performance hit (5x-15x with 5x-10x increase in memory) and has a non-zero false positive rate. So it’s not a “use almost always during development thing” like the address sanitizer is. That said, it’s can

No hiring process is perfect, but when your company’s hiring process is more complicated than my college admission process, it’s a bad sign. If I wanted this I’d have stayed in academics, with its 20-page CVs and multiple statements of purp

Please define “normal”. Normal C++ for me runs the gamut of looking a lot like C to be a template metaprogramming monstrosity. Almost all C++ code interacts with bare pointers at some point. And that’s just one of the places where you get

It transfers money from grant funds into the University general fund, where it can be used for other purposes, like paying for less lucrative departments and administrative salaries. More or less, this plus the ph.d. student’s stipend is th

As a different perspective: I end up writing a fair bit of code that involves data structures and algorithms. Runtime complexity does come up in my line of work, and I've definitely had to solve a couple of issues related to code bein

Whenever I’ve profiled compile times, parsing accounts for relatively little of the time, while the vast majority of the time is spent in the optimizer. So at least for my projects it’s a modest (maybe 10-20%) speed up, not the order of mag

Grueling rounds of leetcode interviews and system architecture questions doesn’t exactly select for either common sense or detailed knowledge of either human nature or even retail.

Being paid tip-dollar isn’t the biggest motivating factor for most people. Feeling like you’re undervalued or being taken advantage of? That’s a huge factor in someone leaving. Being paid substantially under market? I would feel both under

There’s a lot of C++ code out there and a lot that interfaces with C. RAII is one method of cleanup but it doesn’t work in all situations. One that comes to mind is detecting errors in cleanup and passing them to the caller. So it’s not ri

`char * const a` is a different type from `const char *a`. In the first, the variable `a` is const, but `*a` is not const. That is, you cannot change the value of `a` but you can change what it points to. In the second `a` is not const, but

In contrast, there are a lot of systems out there designed to scale up really quickly, but never achieve the product-market fit to ever need this. All that engineering for scalability would have been better applied toward things to find the

Sure. But that's not what keeps systems written in COBOL or MUMPS. It's not what's kept the US air traffic control system running on 1970s-era hardware and software until very recently. Humans are perfectly capable of rewr

It’s hard to predict much about 10 years out, let alone 1000. But we keep expecting languages like COBOL and MUMPS to die, and they keep living on. I think there’s a almost 100% chance that 1000 years from now, when all that’s left of human

The problem with this line of thinking is that it's essentially doom-scrolling. It's especially bad because ChatGPT came along during an industry down-cycle. An interesting thought experiment is: if hiring was like 2021, would y

Exactly. These are all R&D tools and papers. I think the criticism is quite valid if you look at actual products. It’s also a fair criticism of most of big tech wrt AI, and a lot of AI/ML: there’s a lot of cool-sounding R&D, bu

You can, and your program will call std::terminate if there’s already an exception being processed. Not exactly desirable if you’re trying to write code that ensures careful resource cleanup. Also why it’s widely regarded as _wrong_ to ever

This is one of those half-true claims that C++ aficionados make, probably because they can play a bit fast and loose with resource cleanup in their particular situations. RAII simplifies some of the resource cleanup, but at a cost: if the r
