Agreed, I don't like that about Make at all. But also it's never something I have to worry about. Pretty much every syntax-aware text editor knows how to handle Makefiles, and knows that recipe steps start with a tab (unless you c

For sure. But you also don't have to use file-based deps if you don't want. Make doesn't require it in any way. You can mix-and-match.

If you don't want them, don't use them. Make doesn't need you to produce actual files called 'clean', 'build', etc. you don't even have to do anything special unless your build folder has actual files

If Just grew to have a large enough feature-set that it could replace GNU Make, it would collect an equal amount of warts and sharp-edges along the way. It's a little more user-friendly, but not enough to justify how much power you los

Just is fine, don't get me wrong. But Make targets can take arguements too. They just have to be named, or (if you stretch the definition a bit) wildcard targets. AFAIK, Just doesn't have any way to mark "this task is complet

If you're on PG&E for your electricity and you'd be using the grid to charge your car, a gas vehicle is cheaper per-mile than electric at the current kWh prices. And that will probably be true for many years to come. That&#x27

Yes, that's true. But if the concern is build-times, exposing the data layout is harmless. We don't necessarily need full PIMPL just to get improved build times. By keeping the data layout in the .hpp, you can guarantee that your

You actually don't need to do that at all. It's common style in C++, but the language does not require it. With the right techniques, you can absolutely forward-declare basically all of a class's functionality. Then you can p

Back when I was doing C++ more often, I got a big speedup on my builds (and also smaller binaries) by using C-style forward declarations for everything that I possibly could, including class methods. Method definitions / template insta

Make is leaner and more agile than a custom CLI. It takes no time to get started, and there is no boilerplate. Removing or adding steps is trivial, running shell commands is trivial, and hooking into the dependency graph is trivial. Paralle

My team uses Make to handle the top-level scripting for a Python development project, and it works great. It was pretty easy to set up the correct dependency relationships. Make is a powerful tool. You just have to understand how it thinks

Yes, that's true. But it is "on-by-default" for 95% of desktop Linux machines, with no special action needed.

GNU Make gives me: - tab completion of targets - automatic dependency execution - automatic entry points between every task - result caching - parallel execution Yes, it’s possible to do all of this by hand in shell scri

I think it's kind of interesting to watch the dynamics between Clear, PreCheck, and regular security. I flew out from SFO last month, and the PreCheck line was actually longer than normal security. Clear was a ghost-town. I've alw

I have very conflicted feelings about this. Homelessness is an epidemic, and it can be easy to fall into and hard to escape from. I want to be a compassionate person. On the other hand, the walking trails and parks in my community are dange

A lot of the biggest perceived differences come from temperature, since red wines are usually served at room-temperature. If you ever decide to do a blind test, make sure to control for temperature. I did it, and I had a very hard time pick

Most FPGAs have various kinds of primitives that can be instantiated manually in the middle of a larger Verilog design. Sometimes those primitives can be used to do things that are very hard to make the synthesizer create automatically. In

I agree that a good realtor can provide a lot of value. But the amounts of money involved are crazy. Much too high. The average sale-price for a house in my neighborhood is about 1.4M these days. At a standard 3% commission, that's $42

In the microcontroller space, I think Zig is more of a replacement for C/C++. It's a compiled language, intended to produce optimized code that hits cost/performance targets. Micropython and friends are well-suited for educat

Recommend changing the title from Linux to LUnix. The article is about a UNIX-like OS called LUnix, not about Linux.

Zig's comptime feature is really well designed IMO. It uses an interpreter to let you run arbitrary Zig at compile-time, and you can use it to do code generation, custom types, etc. It's pretty cool.

Incrementing a counter would be one example. Like maybe you want to produce file-00.txt through file-99.txt.

Imagine you had all your build commands in a shell-script. Now imagine that you want to run individual steps from time-to-time, instead of running your whole script start to finish. So maybe you write functions that represent each group of

Is Ruby's "yield" different than Python's "yield"? I use Python generators all the time, and I think they're the bee's knees.

Git does have one big architectural problem IMO - native unit of storage is a blob, not a diff. Things like rebase, cherry-pick, 3-way merge, etc would be much easier in a world where the storage model was “diffs” instead of “blobs”. This w
