I’m voting to close this question because Per @James_D, This question is really off-topic for this forum. It's too opinion-based. Maybe consider codereview.stackexchange.com (though you should check the site first for what is considered on-topic there). That said: The model should not have any references to UI elements, such as labels. The view should observe the model and react to changes, instead of the model directly updating the view. — Sedrick 38 secs ago

Q: How to pass a range?

Jonathan Woollett-lightI need to calculate the average value of points around a given point in a wider field. For this I have a function: fn local_average((x,y):(i32,i32),n:i32,(width,height):(i32,i32),space:&[i32]) -> i32 { let y_range = cmp::max(y-n,0-y)..cmp::min(y+n,height); let x_range = cmp::max(x-n,0-x)....

@Mast Still better received than my Rust question yesterday. I'm wondering if there's too much text in my question.
 
9:36 AM
@Zeta I don't think it's a matter of too much text, more a problem with how it's presented. The structure goes all over the place.
If there's only a small amount of text, that's not as much a problem as when the text is longer.
Sometimes you simply shoot a question under the radar.

@Peilonrayz I guess it is mainly the brown switches and the fact that I can really relax my hands.
I use it in an ergonomic tent setup. I also learned Dvorak once, but that was too confusing because I could not use Dvorak everywhere.
Obviously you start by learning how to blind type with 10 fingers.
I'd probably be faster if it had "Choc" blues. I don't like the amount of key travel especially. I put heavy O-rings on mine, which helps both with the travel and the typing sound.
(the UHK sucks a bit when it comes to the missing function keys for development, hitting F1 is not such a problem with only Mod-1 to hit, but hitting Control-F1...
 
@MaartenBodewes Oh what switches were you using? I have an MX blue and MX brown keyboard, where I personally use the browns as my primary.
 
possible answer invalidation by Zujis Karolis on question by Zujis Karolis: codereview.stackexchange.com/posts/256803/revisions
 
What is an "ergonomic tent setup"? I searched and get tents, I'm thinking you're talking about something else. Yeah, having a non-QWERTY keyboard can be annoying at times. I use Dvorak (wanted to learn to touch type and kept cheating with QWERTY) but never learnt QWERTY afterwards. Installing Arch is a pain now as I got black caps on my keyboard...
I hear O-rings are nice, would you recommend people to use O-rings? Or at the least give O-rings a try? But I guess to really know what you like you have to try everything
 
2:34 PM
I think Code Review would be a better fit because of the code review nature of the OP. — markspace 27 secs ago
 
@Peilonrayz A tent setup is where you lift up the middle part of the keyboard, tilting the halves of the keyboard to the left and right, creating some kind of tent (although, with the parts separated from each other you'd have to know this beforehand). This helps against pronation of the lower arms.
O-rings can make your keyboard more "squishy" so it depends. They make your keyboard reasonably silent, but they won't dampen the upstroke so their utility is limited. Personally I don't like the hard bottoming out that many mechs have.
So O-rings are fine as long as you don't overdo it.
If you would order the UHK now you could choose silent browns instead.

The v2 is a much better keyboard than v1, basically the same idea, but with everything removable and backlit PBT key caps. I've worn down the E on the v1 already.
 
@MaartenBodewes Ahh yes, I can see where the name "tent" came from. Thanks. Yeah moving my hands to where I'd expect the outcome to be I can see the benefit.
Oh, I hadn't thought of the upstroke. Hmm I may have to take the plunge and get me some to see which I like. As I'm not sure if I like the hard bottoming out or not. I know I bottom out my keyboard a lot.
I heard about a keyboard with removable switches, but I can't recall if it was the UHK. Removable keys sounds like such a cool idea though. Can you make your own keyboard layout with the UHK? I recently setup VS Code to have key binds for for movement through lines and windows. Now I kinda wanna be able to just have a special layer for movement for everything

@MaartenBodewes O-rings on a keyboard? Are we talking the same kind of rings you put on bolts and washers?
 
@Mast Yeah, something like this: amazon.com/-/en/dp/B01N75JL0F
@Peilonrayz IIUC: yes. While UHK doesn't use QMK, it has "Agent", see ultimatehackingkeyboard.github.io/agent
 
@Zeta To reduce how far you press the button down?
 
@Mast And to soften the sound. If you press a key with full force, the sound of the key bottoming out might be rather loud.
However, if the travel either gets stopped or damped by an o-ring, the overall noise of the keyboard can be reduced.
 
Fair enough. I usually have my WH-1000XM3 on, so I don't hear my keyboard as much.
 
3:17 PM
I don't mind the sound of my own keyboard. However, I've used a Cherry MX 3.0 with blue switches at work, and most co-workers were delighted when I finally changed it for a brown one.
 
@Mast I hear some people with arthritis, and such, use O-rings to dampen the "blow". If you're bottoming out you're effectively punching the keyboard which can be bad for joints. Where an O-ring acts like a seatbelt
 
This kind of questions are off topic on SO. Maybe try on another StackExchange site (ex: review). — Syscall 59 secs ago
 
@Zeta Oh nice, thanks!
 
@Zeta The colour changed the tone?
confused
 
@Mast Cherry MX Blue switches have a clicky sound. Cherry MX Brown switches only have a tactile feeling.
I'm currently pondering whether I should get a Erdodox or Ergodox Redox (prebuilt). The design seems nice, I'm used to brown switches, and the QMK firmware seems tinkerable. The Plank on the other hand seems too small (and isn't a split design).

Q: Is this community the right place for sharing custom library implementations?

Çağlayan DÖKMEI just implemented one of the C++ STL's containers and looking for some code review. My code has, naturally, more than 1300+ lines. I'm not sure if it is the right place to share my library for a good review. The code, hopefully, doesn't contain any bugs. I just need somebody to say that it is we...

 
3:39 PM
@Mast The switches have specific color stems that indicate the type. Normally you won't of course see the stem as the key cap is on them. Almost all mech keyboards have replaceable key caps (if you can find the right type, anyway).
 
I recently acquired a Dell KB522 and thought that was pretty neat already.
 
The most common ones are Blues, Browns and Reds. Blue = Clicky, Brown = tactile / non-clicky and Red (light linear types mainly for gaming). And then there are now a lot of variations.
@Mast Well, I've typed most of my live on "rubber domes" as we call them. You've got some decent ones, I think the Dell's are OK, but nothing out of the way special.
I definitely prefer an ergonomic rubber dome over a normal mechanical keyboard.
It's also some 330 euro's cheaper than the UHK... you can do nice things with that amount of money.
 
I know the difference between membrane and rubber, but mechanicals are a third category?
 
Mechanicals typically use separate key switches for each key. They generally have a lot of travel, but the main difference is that they actuate before bottoming out. And because they use metal springs instead of rubber domes they are much less mushy.
A well balanced switch of course actuates directly after the click or tactile bump.
 
Ok
 
3:50 PM
They are much more expensive to build than rubber domes though, so they almost died when PC's got cheaper. Having a 300 dollar keyboard makes sense for a 3000 dollar PC, now PC's are much cheaper and are all directly competing, you want a cheap keyboard by default.
Basically on Cherry was left standing, so most switches are now Cherry clones.
They have resurfaced now that there is a keyboard community and because people now spend more on actual ergonomics - finally.

@Peilonrayz Scissor switches have domes underneath. All the other ones are mechanicals. You've got optical switches and even analogue opticals (my Wooting One has those). No, mechanical keyboards do not all have N-key rollover or anti-ghosting.

Maybe I'm the weird one here, but I've never tried to flex my keyboards.
There's a first thing for everything.
Apparently there's a bit of flex to my Dell.
 
Yeah, sometimes I wonder a bit about that too, but the mechs are generally build to last. Generally we don't like flex when typing on it, so they come with steel or alu back plates. Problem with those: when they're bent they stay bent.
 
It will still break your nose, but not as good as a steel plate.

I think something similar was released almost 25 years ago, this is probably the cheap chinese knockoff after the initial one failed.
