Ah the ReactJS emoji!

colejohnson66 wrote at 2021-12-03 18:20:17:

So, is the emoji “tiny” like an atom, or “huge” like React?

tshaddox wrote at 2021-12-03 22:53:22:

React is like 35 KB gzipped. Pretty huge in terms of JavaScript bundle size, but still physically very very small!

colejohnson66 wrote at 2021-12-04 14:54:41:

Oh, for sure. React is pretty small on its own. It's when the whole site is bundled into an SPA that's over 1 MB is it an issue. I wasn't making a jab at React so much as a jab at people using React (IMO) irresponsibly.

It would be better to set the data anyway, and let the code that shows the emojis determine whether to skip the emoji or not.

Neat concept.

As someone not very up-to-date in Web UI techniques, I was curious as to how the array was being advanced on scroll. Unfortunately, it looks like the answer is basically polling. The code constantly calls window.requestAnimationFrame(), checking window.pageYOffset. This means that the page is constantly doing work, even at idle.

Surely the more correct way is to install an onscroll handler or something, right?

have_faith wrote at 2021-12-03 08:31:19:

Request animation frame exists specifically to avoid ‘traditional’ polling. You’re thinking more of setInterval() which is the old way of doing it. The requestAnimationFrame docs are a good read, there are lots of performance benefits.

vincentriemer wrote at 2021-12-03 02:48:37:

The correct way would be a mix of those two strategies: an onscroll handler that schedules an update through requestAnimationFrame (ensuring that it only gets scheduled once until the next frame update actually executes).

goatherders wrote at 2021-12-03 04:22:23:

The correct way is the way that works, which this does.

osrec wrote at 2021-12-03 04:49:36:

dhritzkiv wrote at 2021-12-03 03:50:07:

I managed to force this data to sort-of work by using a pygmy goat at 40-50cm tall, and a mallard deck at 50-65cm long (even larger than the site suggests). So, sure.

But if you use a more typical domestic goat, like an Irish Goat, you get a height of 80-90cm. The length is even longer.

Also, the "running man" being bigger than a cow and about the same size as a horse...

But what really bugs me is that it simply uses some font it finds on your system, so on my slightly outdated Linux version it only shows about 70% of the emojis. I mean, if there was ever a perfect use case for webfonts, it would be this page...

mminer237 wrote at 2021-12-03 14:51:15:

The average man _is_ taller in height than the average cow and shorter in total height than the average horse.

His cow is about the average total height of a cow at 160cm.

He has an oddly short man though at 165cm / 5'5".

And he says the horse is the same size, but that would be only 16 hands. That would be the withers size of an average horse, but the total height of only a pony.

Arm: 30cm. I think my arm is bigger than that. And fire: 40cm. This seems somewhat arbitrary lol

xcambar wrote at 2021-12-03 05:58:25:

Let's play picky:

In anatomy, the arm is the part between the elbow and the shoulder.

Below the elbow is the forearm.

With that in mind, 30cm for the arm is definitively a sound measure... and the name of the emoji is wrong. On every phone, keyboard and app.

tl;dr; what is commonly called arm is in fact arm + forearm. Don't blame the author for being correct.

wartijn_ wrote at 2021-12-03 11:53:12:

The emoji isn't called "arm" though, it's "flexed biceps". Alternative names are: biceps | comic | flex | flexed biceps | muscle. [0]

And every popular implementation shows arm + forearm + fist. [1] Giving only one part of that as the length is just wrong.

Even if it were called arm, I would argue that that should be shoulder to wrist, since that's what commonly called an arm. It's also the definition that Merriam Webster has. [2]

Just so you know, I'm fine with calling "arm" what is between shoulder and wrist.

I was just annoyed that GP seemed to diminish OP's efforts in building their page by nitpicking chosen lengths and terms, and I chose to enter the game rather than nothing.

Your comments are welcome and informative, thank you for that.

Dictionaries are descriptive and not normative, which confirms the common use of arm as "wrist to shoulder".

CRConrad wrote at 2021-12-04 15:27:37:

> Just so you know, I'm fine with calling "arm" what is between shoulder and wrist.

Great. Since that's actually what it _means,_ in ordinary English. What you call "actually correct" "in anatomy" is professional sub-language and has no bearing on this forum. (Or any other, besides fora for professional anatomists.)

Edit: Sorry, replied to your first paragraph before even reading the rest and noticing that you actually agree... I was already slightly annoyed by your previous post, so wrote hastily. I apologize.

Is japan the only country that has its own map as a unicode symbol? If so, is there a story behind it? I would bet on compatibility with some regional encoding that had it to begin with.

wodenokoto wrote at 2021-12-03 09:31:01:

Emoji was basically created to add graphics to Japanese mobile websites in the late nineties when people paid by the byte.

Back then the supplier of the websites also made the phones, and you could only access specific mobile webs depending on your carrier.

The original emoji were mostly create to facilitate online shopping for train tickets for vacation and ringtones. So a lot of these represent travel, food and landmarks.

Edit: this is for Japanese handsets and carriers. That was pretty unclear before the edit

createunderrate wrote at 2021-12-03 08:56:16:

Emoji were created in Japan.

tinus_hn wrote at 2021-12-03 10:03:32:

The original set of emoji was created by one Japanese person in a weekend for a Japanese mobile operator. So these images, like the blood types, the astrology signs and the cats and later the rice ball and the pile of poo are images Japanese people would want to use in their communication.

The Wikipedia page of the creator has some links to the origin story:

The other day I was running a web version of Townscapes on my smartphone, and it worked beautifully and smooth. But this one is so laggy and slow that I barely could scroll to Laptop (24cm), and then just stopped.

How come a real-time 3D rendering is faster then just displaying a few 2D pictures side by side on a screen? Tech these days is weird.

tobyjsullivan wrote at 2021-12-03 07:01:13:

I had the opposite experience with both of those. Can’t run townscapes beyond the first frame render, but this site is perfectly smooth on iOS.

mattigames wrote at 2021-12-03 07:04:29:

Because the page is mutating the CSS "left" property which is known to be extremely slow (should have used translate), and also creating/removing the dom elements, which is also slow. That Townscapes you saw was probably running over WebGL, you can use 2D over WebGL for the speed benefits with libraries like PixiJS (or from scratch but that's not recommended)

franga2000 wrote at 2021-12-03 10:25:10:

Cool idea, but since one one dimension (height?) was considered, you get some weird things like a cactus (12m) being way bigger than a house (7m).

wongarsu wrote at 2021-12-03 13:15:20:

Even more confusingly, it's not consistent about the measured dimension. The car is 1.8m (wide), the firetruck is 2.3m (wide), the tractor is 5m (long), the bus is 12m (long), the statue of liberty is 46m (high), the astrodome is 66m (high).

It would have made more sense to stay with either height or the largest dimension (but that would have been weird for mountains, which often are far wider than high).

rob74 wrote at 2021-12-03 11:16:11:

According to Wikipedia, Saguaro cacti "can grow to be over 12 meters (40 feet) tall". So, a real old and real huge Saguaro _can_ be bigger than your average house (or palm tree):

https://en.wikipedia.org/wiki/Saguaro#/media/File:Saguaro_wi...

. But I would say 99% of them aren't...

Funny idea, but lot of these seem off.

- A chicken egg is taller than 5cm.

- I would say a tulip is bigger than a phone.

- The okay hand sign says it's 21 cm.My hands are larger than average, but definitely smaller than 21cm.

- A duck isn't bigger than a goat.

- An elephant is smaller than a house.

adzm wrote at 2021-12-03 02:33:29:

I think some measurements are widths and some are heights.

fastball wrote at 2021-12-03 03:07:17:

I think they're actually all by height, and if you google them the OP actually matches up. e.g. googling

"duck height": 20 – 30 in (51 – 76 cm)

"goat height": 16 – 23 in (40 – 58 cm)

Maybe it would be better to do them by mass.

A little unfortunate if they just used the automatic Google info results. The duck one is the Indian Runner duck - a Mallard would make more sense per the emoji.

Likely just a regional thing. Ants where I live tend to be slightly larger than our mosquitos, and they certainly have far more volume.

onion2k wrote at 2021-12-03 09:29:39:

_Ants where I live tend to be far larger than our mosquitos._

When you say "far larger", is that twice as big? 10 times bigger? 1000 times bigger? I might have to avoid where you live.

The ladybug one must be way off, where do they have 1cm large ladybugs? That sounds terrifying. I'd say our mosquitos are closer to 1cm, although they're long but thin.

There's more of these which are really weird, like the 12m cactus.

It's probably a seven-spot ladybird; those average about 10mm. I can assure you that they aren't terrifying at all.

Slightly tangential to the author's intent, but is there any way in modern web front ends to discover accurate DPI info of the screen you're on, and therefore at least attempt to create correct physical sizes for UI elements?

0x456 wrote at 2021-12-03 03:23:23:

Some of these don't show up for me (like Saturn). This might work better with a web-font? Although then you'd lose the harmonious platform emojis. I wonder if there's a way to check if a unicode character exists in a font and dynamically substitute, without using canvas.

can16358p wrote at 2021-12-03 10:00:02:

Quick and dirty idea: maybe try rendering it to an offscreen span/div, get its size and compare it to a well known size of what gets substituted for a generic symbol if it doesn't exist, and if the size matches that, replace with something else.

qwerty456127 wrote at 2021-12-03 11:54:29:

The fact we still are using bitmap icons seems really weird to me by the way. We should have switched to SVG as soon as screen resolutions and DPIs (e.g. on handheld devices) started growing.

The popularity of Emoji to me is not good for communication.

Instead of careful and clarity in writing, people choose Emoji to respond to what needs to be more clarified.

So, if it's hard to express your thought, let's pick an Emoji!?

At work, this leads to more trouble in writing. Most of JIRA tickets are mostly non-existent that it's badly written, confusing to the developers and rest of the team.

Emoji might be just one reason for that. But anyway, it just shows the trouble on how people have problem in writing communication.

Do people overuse Emoji ? I don't think this is about overuse or not, it's about people failed at expressing their thought through writing.

Emojis are fast, easy and universally understood, especially across language barriers.

Not all responses between humans need to be written in prose. Using images has been and will continue to be a significant way for humans to communicate with.

You missed the point here. Instead of a clear explanation in written form, people think an emoji is enough, which is a problem. As the author doesn't want to know how other 're feeling , they want to know their thoughts instead.

Perhaps they missed whatever point you were making, but your comment is largely offtopic.

People also use gestures and facial expressions while talking (see Italy for a frequently portrayed nation for this), why not use the next best thing in (non-formal) communication?
