It lets the hacker take over the machine because there are strings which are interpreted as (IIUC, I am not a java engineer) variables within a class, and you can express a remote URL to load a class from, apparently (through something like

Nice hint, thanks :) According to the manpage, -color can be shortened to -c and link shortened to `l`, as `addr` can be shortened to `a`. -br stands for -brief, which knowing makes it easier to remember. ip -br -c a ip -br -c l No

I agree with nhooyr's analysis. The interface{} will anyway transparently "contain" a pointer-to-the-[]byte, in other words, the []byte value itself will be heap allocated. (Note for anyone new to this that the "[]byte-v

Thanks for pointing this out, I fixed it.

Unfortunately there isn't a recording, sorry! What you're seeing is the LLVM IR for the program being printed. As another commenter noted, you can compile the program with make, which just runs `clang` on that IR.

Indeed, I had to take certain liberties in order to cram the talk into 20 minutes! I hope one of the takeaways was that you don't need to implement a parser to get started playing with this sort of thing.

I suppose I was musing more along the lines of "why isn't this a solved problem". Clearly, it isn't an easy one or compilers would already take this into account and then the statistical variance would be reduced.

Great, we can control for layout of code, heap, stack and other effects which mess with a performance measurement. However, why do those things have a (statistically significant?) impact in the first place? I guess that hints that with some

Mutation testing is a neat idea I'd not heard of. Wonder how well it works in practice. Someone's implemented a package for doing it with Go which looks good: https://github.com/zimmski/go-mutesting

At this point in that video, some minutes after the loss of signal, you can hear on the countdown net https://youtu.be/-B_tWbjFIGI?t=42m21s - it's garbled but sounds like "Suspected loss of signal".

Agree it is strange. I love their "How Not to Land an Orbital Rocket Booster" film. https://www.youtube.com/watch?v=bvim4rsNHkQ Watching the countdown net it seemed plausible that they didn't know whether it

I'm confused what the connection is with Chernobyl. But 2M deaths in the last 30 years is not likely correct - this interesting WHO report on the matter suggests the final toll from the radiation would be more like "up to 4k"

Interesting video of Moller himself talking about it (while sitting in one of these cars): https://www.youtube.com/watch?v=gOR_SzLW2Ns There's some grainy test flight footage at the end, too.

While I agree readability is key, you may find people who disagree about what constitutes "readable". I think the Go community in particular may be partially inspired by the philosophy outlined under "Variable names" in

I did this a couple of months ago and got a >5x speedup. It's at the expense of dropping quoting though, so no commas or newlines can be in the input data. https://github.com/pwaller/usv
