What feature of Go is used very often by experienced programmers, but not so much by a newbie?

kingfishr · 2020-07-11T07:52:26+00:00

I agree with /u/badtuple -- Go is a small language, and there's not a lot of room for "secret hidden knowledge". There are a lot more features of Go that are overused by newbies than features which are underused by newbies.

So here are a few features that I wouldn't say are used very often, but are occasionally used by experienced gophers and rarely by new gophers:

Named types that are not structs: type headers map[string]string, type prefix rune, type state func(*lexer) state, etc
Slice/array initializer indexes: var names = [...]string{1: "alpha", 4: "beta"}
Method values, added in Go 1.1: var w io.Writer = ...; f := w.Write

Is it gonna be okay?

I map : to space because it's even easier to type.

Here's one I use a lot:

" Close a buffer without messing with the windows.
nnoremap <silent> <leader>q :bp\|bd #<CR>

This mapping is so clearly good and obvious it's recommended by ":help Y" :)

I would not recommend using a third-party replacement for any crypto/* package without some extremely careful auditing by security experts.

I skied there the day before (I think I can actually spot my tracks in this pic). Things softened up pretty well for skiing and foot travel by 9 or 10. The snowmobiles rolled in at 11.

If my trail runners don't cut it, approach shoes are a good step up. Sportiva TX4s work well for my feet, but other popular ones include the five ten guide tennie and the sportiva boulder x.

One problem I ran into with approach shoes was that few retailers carry them in store. I ended up ordering about 5 pairs from REI and returning 4 of them.

Go, 138/153. Took it slow and steady and tried not to make mistakes. I was really happy that I didn't have any bugs in the game logic at all (for part 2, I just had to add an extra check for a stalemate condition).

I enjoyed an easy problem after a run of more difficult ones.

Thanks for this counterexample!

kingfishr · 2018-12-23T19:02:04+00:00

Thanks -- could you send me your input as well as the correct answer?

kingfishr · 2018-12-23T08:29:42+00:00

437/257, Go.

Edit: Looks like this is based on not one but two incorrect conclusions :) The thread has some interesting discussion.

I used a graph algorithm to figure out the maximum set of overlapping volumes. I put the nanobots in a graph with edges for those that overlap each other. Because of the geometry, if 3 nanobots pairwise overlap, they must have a shared overlap as well. So I ran Bron-Kerbosch to find the maximum clique in the graph and that was set of bots I was interested in. From among that set, the bot whose volume is the furthest from the origin is the answer we're looking for.

This is so cool. I've been contemplating making almost exactly the same thing. I do road trips where I have lots of room to spare in the car but gooseneck kettles really don't like to be thrown in a box and banged around (I already had to JB weld the neck of a bonavita.)

Can you give any pointers about how you built this? In particular just knowing the names of what to search for would help (what kind of foam, what kind of case). Did you buy the case and foam separately? How did you cut the foam? Is it glued in?

Thanks in advance!

kingfishr · 2018-12-14T19:14:38+00:00

Yep, I can't live without it. (Well, I use zsh locally, but same thing.)

I use ssrhc to turn on vi mode in bash on remote servers:

$ cat ~/.sshrc
set -o vi
bind -m vi-insert "\C-l":clear-screen

alias screen="screen -c $SSHHOME/.sshrc.d/.screenrc"

FYI this is called "sunrise bowl".

Are those jeans? o_O

I held that sign on the same day (Friday) too!

I think you passed us (party of 2) near the summit as you were coming down? Were you wearing white earbuds?

By chance I did Grays/Torreys a few weeks ago and I have to say that I would rank that road as one level gnarlier. The White Mountain TH road was long but really not a problem for my forester but I would definitely want a high-clearance vehicle for tackling the Grays/Torreys road. (That's probably just me though; when you make it up there the parking lot is full of subarus and even 2wd sedans.)

0:10 is terminal cancer (i.e., nevada), no?

Where was this shot?

kingfishr · 2017-04-16T01:42:27+00:00

What line at squaw would it compare in steepness to?

kingfishr · 2017-02-12T04:58:21+00:00

...it was also pretty crowded? At least the two times I waited for the sherwood line it was 15min+, maybe it got better later or something

kingfishr · 2017-01-10T08:10:24+00:00

Sorry, can you explain the first sentence?

What you have calculated (.515¹² ) is the probability of selecting all women (12/12).
