I played twinkle twinkle little star

u can enter 'notepat twinkle' after tapping notepat in the corner to actually run through that melody

Nice. If only there was a mario theme song.

I just did it and it didn't jump out for me at all. Odd

I usually find it easier to relax my eyes (focus too far rather than too close), and so the opposite occurred - most of the holds appeared to float in a single plane (slightly wavy perhaps due to lighting differences), while the incorrect hold was sunk further back.

It's so weird ! The badly placed hold just disappears once all the rests aligns. My brain seems to dismiss it as an error on its part

Same, after some practice I could close one eye at a time and see the movement but it was hard to maintain the eye crossing with one eye closed

Took me a bit to realize the last photo has it correctly, and to stop trying to find the discrepancy there. Looking at only the first image it pops out to me because the wrong one is floating closer to my eyes than the rest.

Same! I couldn’t get it to work because that sailboat was in the way.

I just shared this in the work Slack and everyone resoundingly agreed with the sentiment. Definitely going to pay more attention to this now, thanks for sharing!

I tried to learn dvorak, and colemak, and both ended up requiring too much investment to be worth it. This is very tempting, even though I promised myself I'd stop messing with keyboard layouts

I’m not here to convince anyone as I could care less what layout you type in, but are you really saying a few days or weeks of typing slightly slower isn’t worth a lifetime of increased ergonomics and comfort?

> a lifetime of increased ergonomics and comfort

I've never felt any discomfort from qwerty, so, no, this business about increased ergonomics and comfort is a false promise to me.

I have, however, helped multiple people who thought they had problems in their hands and wrists who actually had problems in their necks and shoulders, and showing them diagrams of the brachial plexus nerves helped them eliminate their pain through posture changes.

But there’s the constant switching cost any time you encounter a keyboard that is t yours

How often is that? And, what cost exactly? Just type in QWERTY. It’s just not a big deal.

I haven’t learned Dvorak, but I presume that doing so overwrites a lot of the muscle memory used for qwerty and it’s not like you retain full proficiency in the old layout.

Maybe it’s just me, but I find that I will frequently mistype switching between different warty keyboards (eg, standalone mechanical vs laptop)

I don't know how it works, but when I switched over (20+ years ago) I was dysfunctional in both qwerty and dvorak for a good couple of weeks if not a month, then slowly got the hang of it. I use qwerty now at work and dvorak at home, except that I've switched the main keyboard layout at home to qwerty and just use dvorak for programming and anything in a terminal (on linux), which is where I spend a lot of my time.

I can mentally switch over to dvorak and program for a while, mentally swap back, and type normally for other things. I mainly switched the default layout back to qwerty because I was tired of remapping all the keys in every game I play. Sometimes when I come into work on a Monday morning I'll type gibberish for a couple of sentences then mentally flip back to qwerty and be fine.

I almost exclusively use Colemak-DH and have 0 issues typing in QWERTY when I have to. I chalk it up to my phone keyboard still being in QWERTY so I get enough exposure from that to not forget the locations of the keys (it's certainly not as well retained as it used to be, I no longer remember the location of all the keys in QWERTY from memory). I do use a columnar split keyboard though (Moonlander) so it's possible the radical difference in how I use the keyboard helped to keep the muscle memory separate.

It's like driving stick vs automatic.

So, never?

I get your point in principle. I actually switched to Colemak in college, and it worked really well. Then I got a job doing IT support and it was a pain in the butt to keep switching every time I interacted with a customer laptop.

But now I remote work from home. I can’t remember the last time I touched a keyboard that wasn’t mine.

Same as this?

  (1..20).each do |i|
    puts i if i.odd? || i.prime?
  end

edit - upon testing, I just realized the parent's code prints 10 & 16, my code does not, so not the same.

flipflop basically has a hidden boolean variable for state. Btw, while I HAD used it, i still have no idea what's the scope of that state and when it'd reset itself.

I'm currently implementing my favorite 2 player board game - Raptor - in Ruby, and this article is giving me great ideas for how to structure it better. Thanks so much to the author for writing this up!

Author here, I'm really glad it helped! Thank you for reading. :)

Hi, I'm a software dev who was terrified of dance floors my whole life, and nearly gave up hope that my analytical brain could ever get comfortable with it.

But I kept trying, looking for a clever way around the problem, and I found it! This course is everything I learned during that process, and it's currently free for my birthday weekend, so have at it :)

I think it's really useful to describe your product as an alternative to a well known product. Most people will instantly get it, much more so than a long re-definition of the original product.

Apparently not that well known - I've never heard of it either.

I have no idea what Loom is, I also have the same issue I didn't tell me what the product is and just got confuse and didn't explore further.

Same. I’ve never heard of Loom and (therefore?) I’m honestly not sure how this would be different on a Mac than a QuickTime screen recording. And since the promo images are from a Mac, my first thought is Quicktime is probably safer.

Just to address this comment chain: loom does make it easier to do screen recordings and demos, and additionally has features like timestamped comments and notes and sharing functionality.

The target customer is a business who is making demo videos and needs these kinds of tracking/collaboration/commenting features.

Folks interested in open source maybe want a better offering, don’t want to be locked in, want more favorable pricing, or want a self hosted version.

As someone who has used loom, the value proposition is clear from the title without even going to the website.

It wouldn't hurt if the key sentence from your first paragraph was in the top two paragraphs of the landing page.

I have had the idea for this device bouncing around in my head for so long, I just had to get it out and see; does it exist? Does anyone else want it to exist? Or is it just me?

I'd take that bet, will give me more motivation to prove you wrong ;)

Neat. I always wanted to make a HN bet. I don’t see your contact info in your profile, so please email me some contact at anything@prepend.com and I’ll connect with you in six months to settle.
