What Hacker News says?
I like the "Learn Vim Progressively" guide. It starts with just a few commands, and introduces new ones in small batches when you feel comfortable with the ones you're using. http://yannesposito.com/Scratch/en/blog/Learn-Vim-Progressiv... I'd add windows to your list of things to take a look at once you feel comfortable with the editor. You can split your workspace with ctrl+w followed by 'v' (vertical) or 's' (spli…

HN discussionYou don’t learn Vim that way. Once you get the Vim grammar, you just flow. Verb-adverb-noun. This helped me back in the day: http://yannesposito.com/Scratch/en/blog/Learn-Vim-Progressiv...

HN discussionI was struggling with Mathematica in grad school (it's bread and butter for theoretical physicists, since it is particularly good at symbolic math, and good enough for ancillary numerics, plotting, etc). My previous programming experience included C/C++, Python (numpy/scipy), Matlab/Scilab/Octave, and somehow, getting Mathematica to do things seemed like pulling teeth. Incidentally, around the same time, I was explo…

HN discussionTry this: http://yannesposito.com/Scratch/en/blog/Learn-Vim-Progressiv... This is how I learned Vim, so as far as I know it's the best resource out there.

HN discussionI mastered most of the more commonly known motions, including most of the ones on this page ( http://yannesposito.com/Scratch/en/blog/Learn-Vim-Progressiv... ) and some that aren't on it. It didn't seem to be delivering the promised efficiency improvements, so now I only use it for git commit messages, line editing in zsh, and file processing with macros (which are pretty nice--best way I know of to reformat data; m…

HN discussionI sincerely recommend against LYAH! It takes sooooooooo loooooong to get to the interesting bits that actually make Haskell worth learning an has so many try-to-be-funny examples that it makes you run away screaming... I tried going through it but it was literally oscillating between putting my mind to sleep and making wish to grab a chainsaw :) And the "humor" and "pretty pictures" don't help either... they were mo…

HN discussionWhen I was new to Haskell (and also not an experienced programmer), the following example on “functional style” had a huge positive impact on me -- where the same program is re-written in ten different ways, each time making it more modular & composable: http://yannesposito.com/Scratch/en/blog/Haskell-the-Hard-Way... (section 3.1... Feel free to ignore everything before/after that) It feels so much easier to both un…

HN discussionAlso, no ligature :/ I have ligature on my website by using: text-rendering: optimizelegibility with Computer Modern. For many technical reason, typography on the web is hard. I had written my though about it here (there are images, this is why I simply don't copy/paste): http://yannesposito.com/Scratch/en/blog/Typography-and-the-W...

HN discussionIn fact learning vi/m is a lot like learning to play a music instrument. It is a pain to start using vim. But if you reach a certain level you start improving more and more. Concerning vim, it should takes some weeks to be as efficient than with notepad. I written this article which also might help you: http://yannesposito.com/Scratch/en/blog/Learn-Vim-Progressiv... Don't give up! It will pay faster than you think.

HN discussionMainly, I believe that most the energy put in Yesod goes on the problem I find the most important. - Security by default, directly imported from the Haskell type system. - Fast, also, because Haskell is quite fast compared to most languages used for the web. - Able to manage a lot of concurrent connexions, - Incredible foundation language, Haskell is simply awesome (look at my latest blog post for details[^1]).

Lol. > Until here I believe it goes in the right direction.

HN discussionThe difference doesn't matter when you have a shallow structure and can access fields directly and have a few lines of code. But field access does not compose easily if you have a nested hierarchy of objects. Your natural choice in the "OOP style" is to write a lot of boiler plate to point to each different field you want to get/set. Say you get bored of the tedium and want "higher-order" accessors that compose well…
