lowqon C++ std::move doesn't move anything: A deep dive into Value Categories

I sure don't miss the footguns and raw boilerplate that is having a copy constructor, move constructor, copy assignment operator, move assignment operator, and destructor, per class.

Yes, you should avoid the manual memory management that necessitates writing them. But work with a team of developers fresh out of school and next thing you know your codebase will be brimming with this kind of busywork.

lowqon First kiss dates back 21M years

The internet is an amazing place.

lowqon Everything is Ghibli

"Whoever creates this stuff has no idea what pain is whatsoever."

I think it's clear that he is specifically responding to the the overall soullessness of the technique - to animate without a human understanding of what is being animated. But as others have pointed out this is well before modern AI image gen and I have been corrected in that aspect.

"Well, we would like to build a machine that can draw pictures like humans do"

"Would you?"

"Yes"

Awkward silence

From this I don't think it's difficult to extrapolate his feelings about modern AI image gen. But you are correct in that this is not a direct assessment. Appreciate the correction, thanks.

Guilty as charged. I don't think the leap was far but there was certainly a logical leap. Thanks for pointing that out.

lowqon The Typeset of Wall·E (2018)

Not to mention, 99^6 = 941,480,149,401 ≠ 99,000,000 (which TFA also quotes). But who's to say notation didn't degrade along with the rest of society? :^)

lowqon Show HN: The easiest way to create web UIs for ROS robots

I hear you man. The fact that a `byte` in ROS's bootleg protobuf is actually signed, and `string` is ASCII-only means that if you want to send a file or binary blob you have to use a `uint8[]`, which of course C++ will turn into a `std::vector<uint8_t>`. Good luck turning that into a proper `std::string` without an extra copy. And don't get me started on the comically scattered documentation for any basic use case that only ChatGPT can seem to make sense of. Better yet, the complete insanity that is node parameters - ever heard of reading from a file? Can't believe anyone takes this seriously.

ZeroMQ, protobuf, and a little thought would go a long way at our org.

lowqon Parseback: A pure-Lua introspection library for LuaJIT's FFI ctype objects

It's fantastic when embedding Lua in a self contained executable too! I have a routine that goes through and 'cdef's certain headers that were also #included at compile time. Super powerful extending a C program this way.

lowqon Parseback: A pure-Lua introspection library for LuaJIT's FFI ctype objects

It doesn't run the preprocessor, so you have to expose constants as externs, for example. Things like `int32_t` still work, so it must just have built in support for standard types.

lowqon Where Have All the Websites Gone?

I swear that IKEA filter writeup was on HN once upon a time. That or someone else's thorough analysis of the exact same appliance!

lowqon RAM, Tesla and Subaru Have Worst Drivers, While BMWs Have Highest DUI Rates

Utah's BAC limit is (infamously?) 0.05. A single drink will put you over, or so the rumors go.

lowqon Talking with the inventor of C++ [video]

As a fairly avid Rust user I can say I'm excited to hear that! Just playing a little devil's advocate for fun.

That said I was moderately upset by this Friday after carefully assembling a development container for a project at work. Guess I'll have to make something persistent somewhere if I don't want to twiddle my thumbs before each build.

lowqon Rob Pike’s Rules of Programming (1989)

One might say Electron's algorithmic constant is quite large..

lowqon Rob Pike’s Rules of Programming (1989)

Agreed. I find that "smart objects" are much more difficult to make cohesive with one another. Punting your "smart" logic to a higher level is easier to understand, test, and change.

lowqon MMO Architecture: clients, sockets, threads and connection-oriented servers

Sounds amazing! Did you implement congestion control per connection, and if so, which algorithms did you use? I can imagine that CC could really affect throughput at this scale.

lowqon Always the same warning signs

If the probe was single ended (e.g. not a differential probe or handheld unit), you may have shorted something to ground without realizing it. Was a long time before I figured that one out.

lowqon JavaScript state machines and statecharts

That's a good one. I've been trying to find a source for: "If you try to write your own TCP, you'll end up with TCP, but slow."

Cannot for the life of me figure out where I read this.

I did not expect to find a fellow machine girl enjoyer today!

MG is all about the samples and the breakbeats. Definitely not the chords, haha. But I do wonder how that factors in to mixing.

lowqon Ask HN: Why is the hunger for RAM never satisfied?

Holy cow. I never considered this!

I guess it would also explain why the games I would write in 2011 on a netbook ran so smoothly on every other computer I tested them on, despite using the legacy OpenGL 1.1 API, etc. etc.

As far as configure is concerned, I'd like to add that 16394 is close to 2^14, not 2^16.

lowqon Agile isn’t about speed, it’s about direction

In our process, we've been consistently told that a weight of 8 corresponds to a two week (10d) sprint, and that 80% of our time should be spent on scrum tasks. Then, if any developer closes more than 8 points in a sprint, we are told that we aren't estimating properly. They have all but equated 1 point to 1 day, but the scrum master consistently denies that weight corresponds to time.

I'm new to this. Are we agile?

lowqon Instagram Is Estimated to Be Worth More Than $100B

Millennial here, deleted my account a few days ago.

Unlike most platforms, Instagram cuts strait to the most depressing part: pictures. I've had enough with social media, and I envy those who never created a Facebook.
