How Do I Into Git?

a helpful primer for users sick of git's poorly-named commands

I've used Git since 2011, and this is the stuff that I've always had to Google to remember. I hope it helps you not hate Git so much.

boto3 quick hands-on

This documentation aims at being a quick-straight-to-the-point-hands-on AWS resources manipulation with [boto3][0].

First of all, you'll need to install [boto3][0]. Installing it along with [awscli][1] is probably a good idea as

[awscli][1] is boto-based
[awscli][1] usage is really close to boto's

Linux simple performance tweaks

Change the I/O Scheduler

Open $ vim /etc/default/grub then add elevator=noop next to GRUB_CMDLINE_LINUX_DEFAULT. Run $ update-grub and $ cat /sys/block/sda/queue/scheduler to be sure that noop is being used:

$ vim /etc/default/grub
$ update-grub
$ cat /sys/block/sda/queue/scheduler

	import coremltools
	# Load a Core ML model
	coreml_model = coremltools.utils.load_spec('SentimentPolarity.mlmodel')
	# Convert the Core ML model into ONNX
	onnx_model = onnxmltools.convert_coreml(coreml_model, 'Sentiment Polarity')
	# Save as protobuf
	onnxmltools.utils.save_model(onnx_model, 'SentimentPolarity.onnx')

	'use strict';
	// Simple way to download the model and insert it into the database.
	// Normally would use a tool like mlcp to do this. This only needs to be done once

	declareUpdate()

	AWS AUTHENTICATION
	-------------------

	In order to run any of the code below, you need a profile with AWS credentials
	set up on your computer. It's very easy to do this. Google how to configure
	your profile with boto3, or visit the docs:

	#!/usr/bin/env python

	# Simple [boto3](https://github.com/boto/boto3) based EC2 manipulation tool
	#
	# To start an instance, create a yaml file with the following format:
	#
	# frankfurt:
	# - subnet-azb:
	# - type: t2.micro
	# image: image-tagname
