Quick Tips for Fast Code on the JVM

I was talking to a coworker recently about general techniques that almost always form the core of any effort to write very fast, down-to-the-metal hot path code on the JVM, and they pointed out that there really isn't a particularly good place to go for this information. It occurred to me that, really, I had more or less picked up all of it by word of mouth and experience, and there just aren't any good reference sources on the topic. So… here's my word of mouth.

This is by no means a comprehensive gist. It's also important to understand that the techniques that I outline in here are not 100% absolute either. Performance on the JVM is an incredibly complicated subject, and while there are rules that almost always hold true, the "almost" remains very salient. Also, for many or even most applications, there will be other techniques that I'm not mentioning which will have a greater impact. JMH, Java Flight Recorder, and a good profiler are your very best friend! Mea

Firing up Latex on macOS

Firing up LaTex on macOS 🔥

As I'm writing this small tutorial, I assume you've read my previous one about setting up macOS, so if for any tool I'll use without explanation, look to that other article.

MacTex

The full version IS NOT MANDATORY, as in the tutorial that follows I installed the smaller version of MacTeX and proceded installing every needed dependency. Installing the complete package is about ~3.5GB of download and ~5GB on disk, the smaller one is just about 80MBs.

Click here to download the complete version or here to download the smaller version.

Webhook using self-signed certificate and Flask (with python-telegram-bot library)
#!/usr/bin/env python
'''Using Webhook and self-signed certificate'''
# This file is an annotated example of a webhook based bot for
# telegram. It does not do anything useful, other than provide a quick
# template for whipping up a testbot. Basically, fill in the CONFIG
# section and run it.
# Dependencies (use pip to install them):
# - python-telegram-bot: https://github.com/leandrotoledo/python-telegram-bot

* right click/ctrl click on any entry in the network log, select Copy > Copy All as HAR
* open up JS console and enter: var har = [paste]
* (pasting could take a while if there's a lot of requests)
* paste the following JS code into the console
* copy the output, paste into a text file
* open up a terminal in same directory as text file, then: wget -i [that file]
