Don’t Send a Pin to Do a Text’s Job

9 Apr

Modern messaging clients are pretty amazing. They let you send things like picture, audio, video, and all of them natively viewable within the thread. They also let you sent one other thing, your location, you can send it as your GPS co-ordinates, or as a pin on you map app. Please don’t do that.

Please Don’t Send A Pin.

Here’s why you should not send a pin when someone asks for an address.

  1. The person asked for an address, so just send that. That should be the end to it really.
  2. You have no idea what phone/OS/messaging client the person using, and if it can properly handle a map pin.
  3. There is a much greater chance that it’ll recognize address written in text as an address and handle it as such.
  4. If the destination is a packed neighborhood, a pin can easily direct you to wrong house.
  5. If it’s your address, it should be on the tip your tongue/finger and you can just type it.
  6. Address written in text is universally readable, a pin is not.
  7. I can easily copy-paste address written in text into contact, a pin I cannot.

Of course if the location is inside a forest/national park type of place where an address is non-existent, feel free to send a pin, but know when not to. Most of the times, if asked for an address, don’t send a pin, send the address.

A World full of Aspect Ratio

1 Apr

What is aspect ratio you ask? It’s the ratio between your TV, laptop, tablet, or your phone display’s width and height. Aspect ratio is easily identified by maximum resolution of a display, if you reduce a 1080p display’s resolution 1920/1080, you get 16/9 or the aspect ratio 16:9.

So, what’s this about world full of aspect ratio? While 16:9 has dominated the display market for the past decade or so, it was never quite alone. 16:10 never quite went away, mobile market has seen both 15:9(Nokia Lumia) and 3:2(iPhone), and PC gaming is seeing a huge demand for 21:9 display in recent days. While having different aspect ratios is great for filling every niche in market, it makes it difficult to compare display sizes. A 27” 16:9 display is actually bigger than a 29” 21:9 display, a 5.7” LG V20 with a 16:9 display is bigger than a 5.7” LG G6, which has an 18:9(2:1) display or even a 5.8” Galaxy S8. And it’s not just total area, different aspect ratio also means different device width on a phone, or a different device height for a pc display.

Galaxy S8 has the same display width as a regular 5.2” display phone. A 29” 21:9 display has the same display height as a regular 23” display.

These properties actually make these great choices if they fit your need. As a matter of fact, I am writing this on a 21:9 29” display, it’s amazing for gaming. And the reduced width makes Galaxy S8 much easier to hold than its diagonal size would make you think. But the point of me writing this is that people should know what they are getting, and if you’re reading this I assume you’re the type who likes to know what you are getting.

Diagonal Resolution X Resolution Y Width Height Area
23” 1920 1080 20.05” 11.28” 226.04”
27” 2560 1440 23.53” 13.24” 311.50”
29” 2560 1080 26.72” 11.27” 301.19”
5.7” 1440 2560 2.55” 5.10” 13.00”
5.7” 1440 2880 2.79” 4.97 13.88”
5.8” 1440 2960 2.54” 5.22” 13.23”
5.2” 1440 2560 2.55” 4.53” 11.55”

There is a formula for that, it’s not that hard really, some basic trigonometry can get you here. All I did was make it into an easily pluggable format. You’ll remember I said that the resolution will give you the ratio, which in trig is Tangent value, so adding the diagonal to the mix we can figure out the display’s height and width. And the area is just multiplication, which looks like this,

area

Of course for our purpose we need separate equation for height and width. So,

 

height

Which in MS Excel terms, (SIN(ATAN(resY/resX)))*diagonal

width

Which in MS Excel terms, (COS(ATAN(resY/resX)))*diagonal

Happy hunting! 🙂
