Debug symbols are often larger than the original source code though. The main culprit is C++ template expansions, which can get crazy long.

My solution in this case was to convince my company to buy CLion, which works reasonably well and which I believe is backed by LLDB.

I recently was troubleshooting a crash that backtraced through the boost::sml library [0]. The crash didn't actually have anything to do with the library, but it was used as the core event loop. The backtrace -- as in, just the output

Nothing anymore. Originally it measured a specific dimension on the transistor. Then transistors started shrinking non-uniformly, so they adjusted it -- "how big the transistors would be at equivalent density if they had shrunk evenl

Building them would be a challenge, but definitely not an insurmountable one. I’ve worked on a couple of C++ projects at a similar scale to Windows (millions of LOC) and the build systems were a major pain. But a determined engineer with th

I work in financial data — lots of big ol’ UDP multicast streams getting replicated by big routers in private data centers on private lines. In that context, everything bad can happen, but it rarely does . For example: packets most defin

The Brother HL-L2370DW is in the same price class ($159) and is a solid monochrome laser printer. I'm about 1000 pages in and no issues. Maybe you don't like the dark color scheme, but I find it to be quiet when not in use, unobtr

Sort of. There are a bunch of places in the safe API where you have to care. Off the top of my head: - Lock poisoning and dealing with locks failing to open because they’re poisoned after some other thread panics. - The whole scoped thread

I think the key there is "as much as possible". It's really hard to guarantee that panics won't happen. I like Rust, but the panic mechanism is a bit of a weak point in the language. It's not like I have a better so

Not OP, but price and availability. Before about a year or two ago, it was a cheap-and-cheerful way to put some smarts into any project. Now it's impossible to get at twice the price, and the alternatives aren't quite there yet in

It depends. The best way to strongarm your employer is with another job offer. If you can't get another job offer, or if it's not a big bump up, that probably says that you're being paid competitively. But if you interview so

Thank you so much for reminding me! I remember Hillel Wayne’s post about it from a while ago, and I had only gotten through the first couple of chapters before stuff got in the way. It might be a good long weekend read. Great suggestion!

I think there are two different kinds of consistency, and it's important to not conflate them. There's consistency that's internal to a system. Do all of the foreign keys line up correctly? Have I lost any data that was pro

It’s mechanically solvable but not in any practical timescale. A naive approach would be to check every square with no repeats in the rows, which requires (26!)^26 attempts, or roughly 5e691. Obviously you can improve that by exploiting sym

Yes, for sure. But if you can easily build 20 or 10 or even just 2 stories on top of it, land value decouples from housing value (not all the way, but substantially). And for most people, housing value is what really matters; land value is
