Wow! First week of the August!
It's that time of the week again for the first time this year. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.
Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.
#todayilearned
Summarize a concept that is new to you.
And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

I learned how to interact with spreadsheets programatically via the Google Sheets API, and now my GatsbyJS site has a simple, functional database in the cloud ☁️.
Dunno what I’ll use it for yet, but hey, I’ve got a database 😄
Here's an idea I'm working on myself: Let a user connect theirs and use it to keep your "real" cloud database (e.g. Firebase Cloud Firestore, DynamoDB, FaunaDB) within free tier for as long as possible (or just more affordable in general) by offloading their old sales data (e.g. older than this month, per transaction, whatever) to their own Google Drive account.
I once built a simple jobs board with google sheet as the database and google forms as a way to collect data.
That's actually how I set up comments on my now-ancient personal site (static and built a long time ago with Foundation v5 and an old version of Assemble still based on grunt). I added an "approved" column to the Sheet not available in the form (a Handlebars partial which appended the page URL and submitted to Google Forms via AJAX), so I could moderate the comments in Google Sheets after getting an email of a new Google Forms submission.
It's so old that I don't think I ever got around to updating it after Google changed their CORS policy. Bloop.
Not something technical, but I learned, after spending almost a week blocked in a problem, that talking to someone more senior in the project could save a lot of time! And I also learned to documenting how things work, so future me, and people who find similar problems won't be stuck as well
I actually learn how to use
MutationObserverandIntersectionObserver, quite useful.Yeah!
I learned that Debian has an "alternatives" system. Is like a symlinks manager but for commands that are interchangeable in some way.
For example, I installed neovim and without doing anything I already have the commands
viandvimpointing to a neovim symlink. Nodejs also has one, it's calledjs, I can run a script like thisjs ./path-to-script.js. To see what commands have "alternatives" check the/etc/alternativesfolder.And for more details read the manpage.
Noice!

I learned how XGBoost multi-class classification works.
Turns out that every
n_classestree (read estimator) is for that particular class. Neat way of keeping boosted regression tree leafs restricted to one value.This commit adds support for XGBoost multi-class classification model transformations.
XGBoost handles multiclass classification by having
n_classes * n_estimatorstrees. Then, everyn_classestree corresponds to their respective classesSince Elasticsearch supports multi-valued leaves, we can transform the xgboost format by choosing the appropriate leaf value index given the tree id.
This commit also fixes a minor model transformation bug where if xgboost actually defined the feature_names instead of the default
f1,...fnwe would blow up.closes github.com/elastic/eland/issues/242
Learned some basic cryptography. Generating SSH Keys and GPG Keys.
Learned something annoying about flutter web.
You have to repeat your code 3 times and adjust the parameters to make your site truly dynamic (support mobile, tablet view and desktop view).
All mobile apps have a back buttons (<), if not, it's a menu
There aren't any comprehensive Flutter Game Development courses
Sounds like your learnings/frustations with Flutter would make for a great post Prince! 😉
Definitely going to write about that, thanks. I am mostly learning through code labs and cloning github repos to my machine.
I learned how to run integration testing for my personal website inside of github actions with python and testproject.io.

@nickytonline crushing it with killer gifs
It was one of the job requirements when I was considering working at DEV. "Must be able to crush it with killer gifs" 😂
learn how git works and made my first pull request
Congrats on your first PR!
This week I splitted the reusable code from tsParticles editor for create a new npm package: Object-GUI
It's a different challenge from particles, less creative but the UI/UX is everything in this case
Don't deploy on Friday 😢😂
Oof. Been there.
