Developping on Tezos with custom gas restrictions

| by Thomas Binetruy
Then next Tezos Protocol update, Carthage net, will increase the gas restrictions allowing the development of hungrier smart contracts. In this post, we document how to update these hard limits to arbitrary values letting developers implement contracts in view of protocol updates. For instance, the gas restrictions will increase by multiple folds before the end of the year. We develop on the Tezos sandbox, the simplest is to pull Yourlabs' docker image: Read More

Python 3.8 AST updates

| by Thomas Binetruy
On this Friday night, I decided to give my mini Python to pseudo-Michelson compiler 1 a little polish. I remembered leaving it working flawlessly, so that it’d be easy to get back grinding at it anytime I so desired to. Using the Python AST module as a compiler frontend, I was sure it’d be pretty stable, unlike Marshall code, purposely left undocumented 2. So I gave my code a go, and somehow, my integration test wasn’t working anymore! Read More

Use npm install -g in ~/.local non-root

This articles presents the most convenient way to deal with global node packages as non-root user.

By default, npm install -g tries to write a root-writable directory and greets you with:

django-autocomplete-light 3.4.0 release

| by jpic | django-autocomplete-light python
This release re-enables Python 2 and Django 1.11 support, even though it doesn’t pass all tests because tests rely on dicts being ordered by default which came in Python 3 Also, this release exits from using Django’s vendored select2, and vendors select2 itself with a submodule again, this is to benefit from upstream bugfixes faster

yourlabs django decision

| by jpic | python django
https://github.com/yourlabs/django-decision A Delegative Democracy implementation made in BlackLoop HackerSpace for Les Indignés back in the days I used to squatt hackerspaces in-between gigs (now running my own). It’s a bit old but probably still valid, given the complexity is handled in SQL with a WITH RECURSIVE query. Anyway, hope this will inspire you ! Have a great week
