I've begun the journey of Learning Rust with this book, Programming Rust: Fast, Safe Systems Development 2nd Edition[^]
So far, I like:
1) builds binaries that need no additional runtime to be installed -- produces exe which runs natively.
2) Cargo packaging system is actually quite nice.
3) very C/C++-like so easy to learn, but I can already tell there is quite a bit of protection there so you don't shoot yourself in foot.
4)libraries are named similar to std c libaries so easy to find
5 Unit testing is built-in just decorate method with #[test] and you're ready to go. then run with $ cargo test --- AMAZING
6 syntax is very similar to Kotlin (which I know from Android dev) so at least there is some cross-over learning.
Interesting Thing
Types are like u64, u32 (unsigned), i32 (integer) f32 (float).
Made me laugh because it took me back to the days of hungarian notation[^] which was beat up by C# and VisualStudio and all the people said, "stop using hungarian notation!!" and I finally gave it up. Now, in Rust, it's kind of back. 😆🤓

Hungarian notation is fine for low-level types. The Rust names are even shorter than their analogues in C++'s <cstdint>. But it's an abomination for user-defined types and data in a type-checked language.

Started to learn RUST a while back then got side tracked and am about 10 levels down in the stack. When I finally do unwind I will pick it up again. A lot of promise in the language!

same here, I really want to get back to learning more Rust. I just can't find the time to squeeze it in this last year.

I don't see a connection between the type names you listed and Hungarian notation. The type names are simple, short, and yet meaningfully describe the type.
Hungarian notation on the other hand attempts to encode information about the value's type in the value's name. Microsoft adopted this as a standard, which caused a fair amount of the programming community to follow suit.
Personally I don't like it. The cardinal complaint is that if the type changes, then the value name should change with it. The problems with Hungarian notation are worse than an inconvenience, however. To my mind Hungarian notation violates principles like implementation hiding, since it exposes implementation details in the names. I also find that the prefixes are visual clutter and make the code harder to read. I have a body of code I maintain with hundreds of classes, all of whose names are prefixed by "cls". Utterly worthless clutter.

You mean you didn't like lpszWindowText (long ptr to null terminated string)??? 
Man, I know how to troll on CP, just mention Hungarian Notation. 
I think back in the day when people printed out code to do code reviews (hahahahaha as if anyone prints code now or does code reviews) that Hungarian was kind of nice cuz you knew the type when you looked at it. But I'm glad it's gone too. Put me down for "Happy with the present situation of variable names." Just thought it was funny that the intrinsic types are a slight throwback to Hungarian.

No kidding. That's almost as much of a blitzkreig in the forums as a brace style debate.raddevus wrote: as if anyone prints code now
I will admit to occasionally printing code fragments. Most of the time lately it's to compare struct definitions against interface specifications. I've got one interface now that has these lovely C struct's in the interface spec. The only problem is the compiler being used forces 4 byte alignment, which isn't documented in the struct's. My corresponding definitions therefore have to insert pad bytes to make things line up.

A few years ago the Infernal Revenue Service accused my company of padding their R&D costs, and they wanted proof of the work we'd done. Part of that proof was supposed to be a listing of all versions of all software produced over the preceding five years. Said source code, copied to CD's (this was a while ago), occupied around 120 discs. We make commercial ink-jet printing systems, so we're good at figuring out how much paper will be needed for a job. We estimated a paper listing of the contents of those discs would have required a little over 9 rolls of paper, at 40,000 feet per roll. When we asked them where they wanted the 9+ rolls delivered (each weighing several hundred pounds, and about 5 ft in diameter), they backed off. Just to be a smart ass, I did print out a directory listing of each of the discs. The directory listing alone was an entire case of office paper (2000 sheets).
Oh, and not to brag, but we could have printed those 9+ rolls of paper in about 1 day. We ain't your mama's DeskJet.

Thanks. Like the best stories, the fact that it's true just adds to the fun.

not only this, but cross-compiling (for iOT for instance) is easier should you need it

That’s a little bit Korn-y but I think you were just Bourne that way!

... a way to keep Microsoft Edge from opening to the start page? I have it set to continue last session, but it always opens to a new Google tab and immediately switches to it. I haven't found a way to disable that, but I must be overlooking something.
(Well, maybe not. Many months ago I noticed a bug where if I left Edge running, sometimes when I did something I never pinpointed in other windows (not Edge) a new Google tab would activate in Edge. A few times I found 5 or six of the buggers open without me having been in Edge. MS is failing to impress, although they seem to have fixed that bug, and you can finally use an extension to open a new tab to the front, thankfully.)

Will you accept "never opening it" as a solution?

It is nice to do some things in, though. It isn't my primary browser, although it does feel smoother in many circumstances than my main browser and others I've used.

Switch to Brave?
Sorry, the devil made me say that. 
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

I just switched to Brave -- I'm not kidding. Right after I read your post, I switched.
I switched for two reasons.
1) Brave still has [x] on each tab so you can quickly close a browser tab (firefox has removed that).
2) Brave still has arrows on scrollbar. FireFox just removed that.
See this snapshot for those features in Brave.

I'm running Ubuntu 20.04 desktop. Also, Brave has a sync feature (allows to share history and bookmarks across devices) so I'm happy with that too.
I'm now running it on my MOtorola G7 also.

I'm running FireFox now and there's an x on each tab to close it - I just update to 89.0.1 but it was there prior to that.
One thing I didn't like in the most recent update is the new-tab "button" is hidden until you put the cursor on it - I'm almost used to not accidentally closing tabs (with that x you don't see).
As for scroll bars? I went to a vendor site and there were, top and bottom of scroll bar, arrows !
