A minimalistic Jekyll Theme
<br>
<br>
<a href="https://travis-ci.org/mkchoi212/paper-jekyll-theme"><img src="https://travis-ci.org/mkchoi212/paper-jekyll-theme.svg?branch=master"></a>
<a href="https://raw.githubusercontent.com/mkchoi212/paper-jekyll-theme/master/LICENSE"><img src="https://img.shields.io/badge/license-MIT-blue.svg"></a>
</p>
</p>
<br>
Paper is a minimal Jekyll theme. Perfect for hosting your personal site, blog, or portfolio on GitHub or self-hosting on your own server. The styling is purposely minimalistic so that you can add your own flare to the website.
Live demo of the theme can be seen [here](https://deadbeef.me/paper-jekyll-theme/). I'm also currently using this theme on my [personal blog](https://www.deadbeef.me).
## Features
- Compatible with Jekyll 3.x and **Github Pages**
- Live local reloading for faster development
- **Responsive layout** built-in
- Supports Jekyll's built-in Sass/SCSS preprocessor
- Supports **Google Analytics**
- Supports **Disqus** for commenting
- Minimum Dependencies
- Rakefile for automation
- `rake check` - Check links/html files of the generated site
- `rake clean` - Clean up generated site
- `rake post` - Begin a new post in `./_posts`
- `rake preview` - Preview with livereload on local machine
## Usage
```
git clone https://github.com/mkchoi212/paper-jekyll-theme.git
bundle install
rake preview
```
Then, go to your favorite brower and type in the address `http://127.0.0.1:YOUR_PORT_NUM_HERE` to preview your website.
### Customization
To customize various details - title/description of the website, your SNS accout names, etc - edit the `_config.yml` file.
### Adding posts
```
rake post title="A Title" [date="2012-02-09"] [tags=[tag1,tag2]] [category="category"]
```
This will create a markdown file in the default folder where all posts are stored in Jekyll; `_post`.
If you wish to **change the directory where posts are saved**, go to the `Rakefile` and edit the `CONFIG = { 'posts': CUSTOM_PATH_HERE }`. This will allow `rake post` to know where to save the new posts to.
The **drafts** you are working on can be saved in the `_drafts` directory. When you push your code to the server, files in this directory will NOT be included to the list o posts.

- [In Python](https://rushter.com/blog/python-garbage-collector/), individual objects are collected if the reference count reaches 0, and each generation is collected if `num_alloc - num_dealloc > gc_threshold` whenever an allocation happens. The GIL is acquired for the duration of generational collection.
- Java has [many](https://docs.oracle.com/en/java/javase/12/gctuning/parallel-collector1.html#GUID-DCDD6E46-0406-41D1-AB49-FB96A50EB9CE) [different](https://docs.oracle.com/en/java/javase/12/gctuning/garbage-first-garbage-collector.html#GUID-ED3AB6D3-FD9B-4447-9EDF-983ED2F7A573) [collection](https://docs.oracle.com/en/java/javase/12/gctuning/garbage-first-garbage-collector-tuning.html#GUID-90E30ACA-8040-432E-B3A0-1E0440AB556A) [algorithms](https://docs.oracle.com/en/java/javase/12/gctuning/z-garbage-collector1.html#GUID-A5A42691-095E-47BA-B6DC-FB4E5FAA43D0) to choose from, each with different characteristics. The default algorithms (Parallel GC in Java 8, G1 in Java 9) freeze the JVM while collecting, while more recent algorithms ([ZGC](https://wiki.openjdk.java.net/display/zgc) and [Shenandoah](https://wiki.openjdk.java.net/display/shenandoah)) are designed to keep "stop the world" to a minimum by doing collection work in parallel.
**Allocation**: Every language has a different way of interacting with "heap" memory, but the principle is the same: running the allocator to allocate/deallocate memory takes time that can often be put to better use. Understanding when your language interacts with the allocator is crucial, and not always obvious. For example: C++ and Rust don't allocate heap memory for iterators, but Java does (meaning potential GC pauses). Take time to understand heap behavior (I made a [a guide for Rust](https://speice.io/2019/02/understanding-allocations-in-rust.html)), and look into alternative allocators ([jemalloc](http://jemalloc.net/), [tcmalloc](https://gperftools.github.io/gperftools/tcmalloc.html)) that might run faster than the operating system default.

**Data Layout**: How your data is arranged in memory matters; [data-oriented design](https://www.youtube.com/watch?v=yy8jQgmhbAU) and [cache locality](https://www.youtube.com/watch?v=2EWejmkKlxs&feature=youtu.be&t=1185) can have huge impacts on performance. The C family of languages (C, value types in C#, C++) and Rust all have guarantees about the shape every object takes in memory that others (e.g. Java and Python) can't make. [Cachegrind](http://valgrind.org/docs/manual/cg-manual.html) and kernel [perf](https://perf.wiki.kernel.org/index.php/Main_Page) counters are both great for understanding how performance relates to memory layout.

Complaining about the [Global Interpreter Lock](https://wiki.python.org/moin/GlobalInterpreterLock)(GIL) seems like a rite of passage for Python developers. It's easy to criticize a design decision made before multi-core CPU's were widely available, but the fact that it's still around indicates that it generally works [Good](https://wiki.c2.com/?PrematureOptimization) [Enough](https://wiki.c2.com/?YouArentGonnaNeedIt). Besides, there are simple and effective workarounds; it's not hard to start a [new process](https://docs.python.org/3/library/multiprocessing.html) and use message passing to synchronize code running in parallel.

Still, wouldn't it be nice to have more than a single active interpreter thread? In an age of asynchronicity and $M:N$ threading, Python seems lacking. The ideal scenario is to take advantage of both Python's productivity and the modern CPU's parallel capabilities.

Presented below are two strategies for releasing the GIL's icy grip without giving up on what makes Python a nice language to start with. Bear in mind: these are just the tools, no claim is made about whether it's a good idea to use them. Very often, unlocking the GIL is an [XY problem](https://en.wikipedia.org/wiki/XY_problem); you want application performance, and the GIL seems like an obvious bottleneck. Remember that any gains from running code in parallel come at the expense of project complexity; messing with the GIL is ultimately messing with Python's memory model.
