For each Ruby module/class, we have Ruby methods on the left and the equivalent | |
Clojure functions and/or relevant notes are on the right. | |
For clojure functions, symbols indicate existing method definitions, in the | |
clojure namespace if none is explicitly given. clojure.contrib.*/* functions can | |
be obtained from http://github.com/kevinoneill/clojure-contrib/tree/master, | |
ruby-to-clojure.*/* functions can be obtained from the source files in this | |
gist. | |
If no method symbol is given, we use the following notation: |
ּ_בּ | |
בּ_בּ | |
טּ_טּ | |
כּ‗כּ | |
לּ_לּ | |
מּ_מּ | |
סּ_סּ | |
תּ_תּ | |
٩(×̯×)۶ | |
٩(̾●̮̮̃̾•̃̾)۶ |
if ($.inArray('something_strange', neighbourhood) != -1) { | |
ghostbusters.call(); | |
} |

Haskell is cool! | |
Here are some reasons why. | |
(This is a Literate Haskell file, so you can load it and then follow | |
along with the examples by running `ghci whyhaskelliscool.lhs`) | |
"Pattern matching" syntax for defining functions is cool, letting you | |
avoid 'if' statements and simply write out the different behaviors of | |
a function: |
Latency Comparison Numbers (~2012) | |
---------------------------------- | |
L1 cache reference 0.5 ns | |
Branch mispredict 5 ns | |
L2 cache reference 7 ns 14x L1 cache | |
Mutex lock/unlock 25 ns | |
Main memory reference 100 ns 20x L2 cache, 200x L1 cache | |
Compress 1K bytes with Zippy 3,000 ns 3 us | |
Send 1K bytes over 1 Gbps network 10,000 ns 10 us | |
Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD |
* Only the releases of the stable versions are listed in principle. The releases of the unstable versions especially considered to be important are indicated as "not stable." | |
* The branches used as the source of each releases are specified, and the branching timing of them are also shown. BTW, before subversionizing of the repository, the term called "trunk" was not used, but this list uses it in order to avoid confusion. | |
* In order to show a historical backdrop, big conferences (RubyKaigi, RubyConf and Euruko) are also listed. About the venues of such conferences, general English notations are adopted, in my hope. | |
* ruby_1_8_7 branch was recut from v1_8_7 tag after the 1.8.7 release because of an accident. | |
* 1.2.1 release was canceled once, and the 2nd release called "repack" was performed. Although there were other examples similar to this, since the re-releases were performed during the same day, it does not write clearly in particular. | |
* Since 1.0 was released with the date in large quantities, the mi |

In this short guide we'll review some new Chrome DevTools features for "function scope" and "internal properties" by exploring some base JavaScript language concepts.
Let's start with closures – one of the most famous things in JS. A closure is a function, that uses variables from outside. See an example:
