Accelerate Python code 100x by import taichi as ti | Taichi Docs –This is almost in the too good to be true category! “Python has become the most popular language in many rapidly evolving sectors, such as deep learning and data sciences. Yet its easy readability comes at the cost of performance. Of course, we all complain about program performance from time to time, and Python should certainly not take all the blame. Still, it’s fair to say that Python’s nature as an interpreted language does not help, especially in computation-intensive scenarios (e.g., when there are multiple nested for loops).”
Why Use MongoDB with Ruby –I haven’t read this yet, but the topic is of great interest: “Before discovering Ruby and Ruby on Rails I was a .NET developer. At that time I’d make ad-hoc changes to my development database, export my table/function/stored procedure/view definitions to text files and check them into source control with any code changes. Using diff functionality I’d compare the schema changes that the DBAs needed to apply to production and we’d script that out separately.”
Runno –It has some similarities with things like JSFiddle or CodePen, but can run Ruby (as well as Python, C and C++). It can even act interactively and accept user input (such as with gets). You can then take these sandboxes and use them on your own pages/blog posts, etc.
Effective Queries with Rails and PostgreSQL –Getting data into your database is easy, but querying large datasets is challenging—especially without the right indexes. Pavel Tkachenko teaches how to write performant SQL queries with EXPLAIN and ANALYZE.
Duplication – Code with Jason –Duplication can pose serious maintenance problems to codebases. Developers’ attempts to fix duplication can even sometimes introduce new problems. Certain popular approaches to addressing duplication exist, such as the rule of three and the refrain duplication is cheaper than the wrong abstraction. I think these advice snippets treat duplication in an oversimplified way that doesn’t […]
CodeSee – Bring visibility to your codebase –CodeSee is the world’s first solution for Continuous Code Understanding. CodeSee helps development teams visually understand how your large-scale codebase works, document it, and collaborate continuously.
VisiData –Command-line interactive multitool for tabular data.VisiData is an interactive multitool for tabular data. It combines the clarity of a spreadsheet, the efficiency of the terminal, and the power of Python, into a lightweight utility which can handle millions of rows with ease.
Zulip: Slack alternative Chat for distributed teams –Now that slack changed its pricing model it may be time to switch. “Zulip combines the immediacy of real-time chat with an email threading model. With Zulip, you can catch up on important conversations while ignoring irrelevant ones”
Everything you need to know –A quirky guide for people joining this particular HCI research lab: “This material should take you a week to go through. It’ll help you in doing HCI work and research in general. 1) Start with a talk by Richard Hamming called You and Your Research about picking research problems: https://ift.tt/2qemNPJ then look over…
Thinking in Hotwire: Progressive Enhancement –Your mental model for Hotwire should be progressive enhancement: start with the basics and layer on Turbo Frames, Streams, and Stimulus as you build more.
Open-source data multitool | VisiData – A very sophisticated tool for working with tabular data. It’s actually a cli and is handy. But I found it a little hard to learn. Still good to be aware of it!
SSH Tips and Tricks | Carlos Becker –Since I joined Charm, I’ve been working and learning more about SSH, and I thought I would share a few quick tips and tricks with you. Forward Yubikey Agent If you use a Yubikey (you should), you can use it in your remotes by having the key in a SSH agent and forwarding it. To manage the agent, I strongly recommend yubikey-agent. You can then forward it in your ~/.ssh/config like the following:
Marta – A sophisticated new FInder replacement or at least supplement. Seems to be a little like Norton Commander coming back. Probably not as good though !
How Kubernetes Reinvented Virtual Machines (in a good sense) –Pretty good high level explanation of Kubernetes concepts. “How Virtual Machines have been used to deploy services. What old problems containers solve and what new problems create. How Kubernetes used containers to recreate Virtual Machines?”
