Using OpenFrameworks with Visual Studio Code (macOS)

First, install the cpptools extension in studio code
Then add the include paths in the c_cpp_properties.json file.

If a small light bulb icon (💡) appears near the include statements on any of your source file, just click it in order to access the c_c_pp_properties.json file.

If there's no 💡 icon, then in the project directory create a hidden folder called vscode:

wget https://github.com/patric-r/jvmtop/releases/download/0.8.0/jvmtop-0.8.0.tar.gz
tar -xzvf jvmtop-0.8.0.tar.gz
rm -rf jvmtop-0.8.0.tar.gz
chmod +x jvmtop.sh

./jvmtop.sh

AWS CLI JMESPath cheatsheet

Random query recipes of JMESPath for the AWS CLI tools that I might have written or stumbled upon.

Examples

Miljö för Kaggle-aktivitet

Det finns en uppsjö av verktyg, språk och bibliotek som kan användas för olika typer av ML. För att vi ska få en gemensam bas så kommer vi att de första två dagarna att utgå ifrån några av de vanligaste, Python och Tensorflow.

Runtime

Nedan kommer två olika sätt att sätta upp detta på din dator, Docker och Anaconda. Docker är det som kommer att ha minst inverkan på din dator (särkilt om du redan har Docker installerat) medan Anaconda ger en mer integrerad upplevelse. En nackdel med att använda sig av Docker är att det inte kommer att finnas någon möjlighet att plotta data.

Docker

Docker finns för Windows, Mac och Linux och kan hämtas här. Docker for Windows kräver Hyper-V vilket medför att virtualisering måste vara påslaget i BIOS samt att det krävs Windows 10 Pro eller Enterprise.

	# Automated AMI and Snapshot Deletion

	#
	# This script will search for all instances having a tag named "Backup" with a value of "Backup".
	# As soon as we have the instances list, we loop through each instance
	# and reference the AMIs of that instance. We check that the latest daily backup
	# succeeded then we store every image that's reached its DeleteOn tag's date for
	# deletion. We then loop through the AMIs, deregister them and remove all the
	# snapshots associated with that AMI.
