Businesses, researchers, and developers all over the world have used the X Developer Platform to creatively innovate, gain valuable insights, and shape the future. Explore how they did it and get inspired to use the APIs in your own way.
Writing is a fantastic tool for processing and communicating abstract ideas. And developers are steeped in abstract ideas! From system design to the finest implementation details, we keep a tremendous amount of information in our heads.
You can use a dev journal to keep track of your emotions, too. Morning Pages are a popular technique for clearing the "clutter" in your head at the start of each day. You can try this approach with your dev journal. Are you nervous, anxious, excited? Get these feelings down on paper so you can clear your head and give the technical problems your undivided attention.
At the start of each working session (this could be a day, ticket, or pomodoro session), define your goal for the session, even if it seems really obvious. What do you want to achieve today? Do you have a clear, well-defined coding task you need to accomplish? Do you need to explore something in the codebase? Are you prototyping? Do you need to test a hypothesis? How will you reduce the ambiguity?
Get in the habit of writing at the beginning and end of every coding session. Keep the journal nearby; it should always be a tab away. You should be able to check your notes or make more notes at a glance.
As I said earlier, your dev journal should include whatever you need to be effective. For example, after experimenting with Morning Pages in my personal life, I found it useful to voice my anxieties and negative self-talk.

But still, most people just pretended that a byte was a character and a character was 8 bits and as long as you never moved a string from one computer to another, or spoke more than one language, it would sort of always work. But of course, as soon as the Internet happened, it became quite commonplace to move strings from one computer to another, and the whole mess came tumbling down. Luckily, Unicode had been invented.
There is no real limit on the number of letters that Unicode can define and in fact they have gone beyond 65,536 so not every unicode letter can really be squeezed into two bytes, but that was a myth anyway.
Well, technically, yes, I do believe it could, and, in fact, early implementors wanted to be able to store their Unicode code points in high-endian or low-endian mode, whichever their particular CPU was fastest at, and lo, it was evening and it was morning and there were already two ways to store Unicode. So the people were forced to come up with the bizarre convention of storing a FE FF at the beginning of every Unicode string; this is called a Unicode Byte Order Mark and if you are swapping your high and low bytes it will look like a FF FE and the person reading your string will know that they have to swap every other byte. Phew. Not every Unicode string in the wild has a byte order mark at the beginning.
Thus was invented the brilliant concept of UTF-8. UTF-8 was another system for storing your string of Unicode code points, those magic U+ numbers, in memory using 8 bit bytes. In UTF-8, every code point from 0-127 is stored in a single byte. Only code points 128 and above are stored using 2, 3, in fact, up to 6 bytes.
There are hundreds of traditional encodings which can only store some code points correctly and change all the other code points into question marks. Some popular encodings of English text are Windows-1252 (the Windows 9x standard for Western European languages) and ISO-8859-1, aka Latin-1 (also useful for any Western European language). But try to store Russian or Hebrew letters in these encodings and you get a bunch of question marks. UTF 7, 8, 16, and 32 all have the nice property of being able to store any code point correctly.
