🥷 Clojure Pro Tip 4
In case you don’t know it, we can use raw strings, like embedding JS code, in hiccup.
I just found out we can use `raw` to prevent strings from getting escaped.
I should’ve found this at the beginning, as it’s mentioned on the homepage, but somehow I missed it.

Clojure Pro Tip🥷 2
So you're more than excited to find out how #clojure thread macros can make code clean and concise, you just love it! But at some point you'll be trapped a bit as the threaded argument's positions are inconsistent using -> or ->>.
Luckily, you can use as-> (see the pic)

It's amazingly easy to group things in #Clojure. The core provides a group-by function directly. Together with many built-in functions or key functions, it creates tons of possibilities, and we can also bake our grouping function if none is satisfying.

Clojure Pro Tip🥷
In #clojure, we can use comment for tests in development. However, since a comment evaluates to nil, you may run into surprising results/errors if you misuse it.
In these cases, you may tend to use ; to comment them out, but a better choice is to use the discard reader symbol #_.

Clojure practice tip💡
Even if we might not have the opportunity to code in #clojure at work, we can still use it for ad-hoc scripting or proofs of concept. I promise it’s a lot of fun, thanks to the interactive development approach. We can try out ideas, building stuff bottom-up or top-down.

Emacs Pro Tip🥷
Having too many buffers isn't good for switching buffers in #emacs.
After finishing a project, we'd better close all its buffers. How?
1. C-x C-b opens up ibuffer
2. Click at the top to sort by that column, or hit s f
3. Mark them by m, then hit D to close them

😂Suffered one side effect of writing too much #clojure while opening an issue for libpython-clj, an incredible lib bridging clj and #python:

Now my blog site starts to look more like one on #clojure and #emacs, when you click on one of the nav bar items, you're actually "calling" a function 😬:

It’s very nice that someone happened to buy me a cup of coffee while I’m planning to rewrite the website: texttoolkit.com, thanks! It was written using #flask years ago, time to brush it up a little bit.

Finally, I get started using lein to set up a #compojure project. But then I got stuck on how to start an nREPL for #cider.
It turned out that there is an option in :ring, which somehow isn't mentioned in lein-ring's docs. I found out it thanks to this answer: stackoverflow.com/a/28759905

Anyone had the experience to successfully publish a chrome extension in #clojurescript to chrome web store? Just noticed it says “Obfuscation is disallowed”, damn!
