  9 reasons to use Zsh

Like majority *nix users, I have been using bash for many years. Sometimes I feel uncomfortable with bash. I tried use some other shells as well such as ksh, tcsh and zsh which I am going to talk about. A few days ago, I found an open source project ranking in the 6th named oh-my-zsh on Github, I downloaded it and had a try with it. It's amazing. We should use zsh to replace bash now. Why do we need to use zsh? Here is a 4 minutes YouTube video which shows many reasons why we should switch from ...

  Valid JavaScript variable names

Did you know var π = Math.PI; is syntactically valid JavaScript? I thought this was pretty cool, so I decided to look into which Unicode glyphs are allowed in JavaScript variable names, or identifiers as the ECMAScript specification calls them. Reserved words The ECMAScript 5.1 spec says: An Identifier is an IdentifierName that is not a ReservedWord. The spec describes four groups of reserved words: keywords, future reserved words, null literals and boolean lite...

  Building the new AJAX mail UI part 2: Better than templates, building highly dynamic web pages

This is part 2 of a series of technical posts documenting some of the interesting work and technologies we’ve used to power the new interface (see also part 1, Instant notifications of new emails via eventsource/server-sent events). Regular users can skip these posts, but we hope technical users find them interesting. As dynamic websites constructed entirely on the client side become de rigueur, there are a number of templating languages battling it out to become the One True Wayâ„...

  Functional Programming in C++

Probably everyone reading this has heard “functional programming” put forth as something that is supposed to bring benefits to software development, or even heard it touted as a silver bullet.  However, a trip to Wikipedia for some more information can be initially off-putting, with early references to lambda calculus and formal systems.  It isn’t immediately clear what that has to do with writing better software. My pragmatic summary:  A large fraction of th...

  Avoiding and exploiting JavaScript's warts

One's sentiment toward JavaScript flips between elegance and disgust without transiting intermediate states. The key to seeing JavaScript as elegant is understanding its warts, and knowing how to avoid, work around or even exploit them. I adopted this avoid/fix/exploit approach after reading Doug Crockford's JavaScript: The Good Parts: Doug has a slightly different and more elaborate take on the bad parts and awful parts, so I'm sharing my perspective on the four issues that ha...

  Deep Understanding of ReentrantLock: Unlocking the Mysteries of Java Concurrent Programming

ReentrantLock introduction ReentrantLock is a class in the Java concurrent package, java.util.concurrent.locks, and is an implementation of the Lock interface. As its name suggests, it is a reentrant mutual exclusion lock. A mutual exclusion lock is a synchronization tool used to protect shared resources, ensuring that only one thread can access the resource at a given time. Reentrant means that a thread can acquire the same lock multiple times without causing a deadlock. This lock provides some...

  Programming Language Readability

Lets compare some Python to Haskell for solving the same problem.  The problem we’ll pick is Trie data-structure for auto-completions.  We are interested not so much in the nitty gritty of the algorithm, but in the language style itself.  Auto-complete has been in the programming news a lot recently; both a Python and a Haskell solver have turned up. (I suspect this post got flagged on Hacker News :(  It never got on the front-page despite the rapid upvoting on a n...

  Why learning Haskell/Python makes you a worse programmer

I've found, contrary to what you sometimes read, that learning Python and Haskell has not improved my programming using other languages. Haskell in particular, being so different from imperative languages, is supposed to give new insights into programming that will help you even when you are not using the language. My current experience doesn't exactly tally with this, and here is why:Demotivation.I find I think in Python, and even in Haskell to some extent, even though I have used Has...
