Thoughts on technology, movies, and everything else
Category: Web work
These days, most of my work is very related to the online world.

Tables on the web are always challenging. Whether you do them by hand, or with the help of a framework or library, they often carry a lot of complexity, performance costs, and compatibility issues.
Recently I came across jExcel, which seems to be quite powerful, with lots of advanced features, and, at the same time, rather simple to use. The recent release of version 3, brings even more features and improves on the existing ones:

Full screen flag
Native color picker
Better mobile compatibility
Better nested headers compatibily
Amazing keyboard navegation support
Better hidden column management
Great data picker: dropdown, autocomplete, multiple, group options and icons

Th resulting SVG files can be used as quick demos and guides in READMEs on GitHub, or as tutorials for your application’s website.
“How HTTPS Works in 10 Minutes” is a simple, high-level overview of how HTTPS works. It doesn’t dive into too much detail or heavy math. But it does cover the main stages of how the connection is established, verified, and encrypted. These are the stages that are covered:
You go to an HTTPS website via your browser
The Client says “Hello”
The Server says “Hello”
The Client makes sure the SSL certificate is legitimate
The Client gets the public key from the SSL certificate
The Client uses the public key to make more random bytes
