Logical Fallacies in The Lab

I found a cool blog about logical fallacies, here's all of its images :3 (until today: 15), check their blog for more updated content :3

Beautiful Fallacies Infographics

Coolest! Thing! Ever! :3

Javascript ES6 to ES5 Transpiler

When you are so eager to use ES6 features but you know that most browsers not yet implement all ES6 features completely (that's why there are also HTML5 pollyfills). Here's the list of transpiler to convert Javascript ES6 to ES5:

• Google's Traceur Compiler
• Google's Caja (client-server)
• Babel (if not sure, use this one)
• Termi ES6 Transpiler 
• full list here and here (with pictures)

Almost 2 years ago comparison between Babel and Termi. Oh and yes, you can use Babel with WebStorm.

Note that every transpilers (CoffeeScript, TypeScript, Elm, Haxe, etc) suffer the same problem: compile duration (hey, one more thing to do [=minify] before testing/deploying) and hard debugging (easier if you use source maps, only for JS transpilers, I don't know if these things exists for transpiler for other language). Still I wish for wAsm to come faster. Btw I learned ES6 just for react-native-web, otherwise I would always still stick with ES5.

Programming Language Libraries

Woot woot! I found a website that crawls for libraries *__*)b
And I think it awesome that Go got first rank.

By Language/Editor

By Package Manager, note:

go (go get), npm (js), rubygems (ruby), maven (java), packagist (php), pypi (python), nuget (.net, c#, vb.net, and f# mostly), bower (js), wordpress (php), cpan (perl), cocoapods (objective-c and swift), clojars (clojure), meteor (js), cran (r), hackage (haskell), atom (text editor), cargo (rust), homebrew (osx), emacs (text editor), swiftpm (swift), hex (erlang, elixir), pub (dart), sublime (text editor), platformio (iot), julia (julia), carthage (objective-c, swift), dub (d), haxelib (haxe), jam (js), elm (elm), alcatraz (xcode ide), nimble (nim), inqlude (qt), shards (crystal)

So many migrating to Go ^^. If it's not about migration, there's a lot more here that apparently choose Go (interviews, from X to Go, and also more here).

NOTE: this list will be no longer updated, you can see the lastest changes on github repo so anyone can contribute/update.

Btw why not MongoDB or CockroachDB.. but I think now they are getting better.

If you found any more news like this, paste the link on the comment, I'll gladly add them on the list.

Faster than Go? Yes, plenty

Is there anything that faster than Go? yes, there are plenty, but I'm not sure if it would be fun to code with.. What are they?

G-WAN

G-WAN is closed-source web application server (not a language like Go). If I'm not mistaken G-WAN caches GET request, so second hit within few ms won't execute the backend function, practically this is cheating for benchmark (not merged), but for real application this feature quite great (can cope up with DDOS attack) :3 Btw did I mention that this web application server support whole lot of language? asm, C, C++, C#, D, Go, Java, Javascript, Lua, Objective-C, Perl, PHP, Python, Ruby, and Scala with CGI-like writing. One note that you must really learn how HTTP works (parsing header, setting cookie, parsing POST parameters, etc) if you want to use this.

I don't really know if this suffer the same problem similar to others that use CGI instead of FastCGI: connection pooling to database (but we can use pgpool).

LWAN

LWAN is also web application server that uses C, can be used with LuaJIT (fast implementation of Lua). For the framework you can use Sailor (Example).

PyParallel 

PyParallel is a programming language implementation, forked from Python3, removes GIL (Global Interpreter Lock).

Julia

Julia is one awesome programming language that uses LLVM, it focuses

Actually there's a lot more implementation that faster than Go for certain (or all) cases, such as: C, C++, Ada, Rust, Java, and Fortran, be sure to check on BenchmarkGame site.

But, don't choose a language or web framework or web application platform just based on performance, there's a lot of things to consider, for example:

• either it's waste of time to work with (since you must do many things manually aka there's no framework or so little libraries/function yet)
• how easy it's to train a new programmer to work with you or continue the project
• what's the continuity of the technology (if the project abandoned by the author/maintainer)
• build/compile duration
• etc..

If you are looking for next hype? try Elixir and Phoenix.

Websocket Benchmark

Once again, today I found another benchmark, about websocket:

Sinatra-like Web Framework Benchmark

So today I come across some benchmark about sinatra-like web framework at 20 July 2016, it compares:

• Gin and Martini (Go 1.6.3)
• Phoenix and Plug (Elixir 1.3.2, Erlang/OTP 19.0.2)
• Express Cluster (NodeJS 6.3.0)
• Sinatra and Rails (Ruby MRI 2.3.1)
• Play (Scala / Java 1.8.0_51)

You can see the details here.

Installing AeroSpike on ArchLinux

As benchmarked previously (more than half year ago since this blog post written), AeroSpike has awesome search/retrieval performance. In this tutorial we will learn how to install AeroSpike on ArchLinux

wget -O aerospike.tgz 'http://aerospike.com/download/server/latest/artifact/tgz'
tar -xvfz aerospike.tgz
cd aerospike-server
./bin/aerospike init

Configure the etc/aerospike.conf into something like this:

service {
  user YOUR_USERNAME
  group YOUR_GROUP
  run-as-daemon
  paxos-single-replica-limit 1 
  pidfile /home/YOUR_USERNAME/aerospike-server/var/run/aerospike.pid
  transaction-queues 8
  transaction-threads-per-queue 8
  transaction-pending-limit 255 # HOT KEY ERROR WORKAROUND FOR INCREMENT
  proto-fd-max 15000
  work-directory /home/YOUR_USERNAME/aerospike-server/var
}

logging {
  file /home/YOUR_USERNAME/aerospike-server/var/log/aerospike.log {
    context any info
  }
}

mod-lua {
  system-path /home/YOUR_USERNAME/aerospike-server/share/udf/lua
  user-path /home/YOUR_USERNAME/aerospike-server/var/udf/lua
}

network {
  service {
    address any
    port 3333 # USE DIFFERENT PORT IF CONFLICT 
    #reuse-address # COMMENT/REMOVE THIS PART
  }
  heartbeat {
    mode multicast
    multicast-group 239.1.99.222 # CHANGE address INTO multicast-group
    port 9918
    interval 150
    timeout 10
  }
  fabric {
    port 3331 # USE DIFFERENT PORT IF CONFLICT 
  }
  info {
    port 3332 # USE DIFFERENT PORT IF CONFLICT 
  }
}

namespace test {
  replication-factor 2
  memory-size 4G # CHANGE DEPENDS ON YOUR RAM
  default-ttl 0 # CHANGE 30 days, use 0 to never expire/evict.
  storage-engine device {
    file /home/YOUR_USERNAME/aerospike-server/data
    filesize 128M # MAX SIZE OF EACH FILE
  }
}

Then start the server:

./bin/aerospike restart

tail -f var/log/aerospike.log &

./bin/aerospike status

First and last command should show something like this:

info: stopped

info: started

info: process running

Done, now you can test your aerospike server using any client :3

aerospike-tools only available on Debian, Ubuntu, and Redhat.

How to become AUR package adopter?

AUR is ArchLinux User Repository, similar to Ubuntu's Launchpad.
To adopt an orphaned package it's easier than you think! adopt now :3

What you need to do is register, find an orphaned package, then click on the "Adopt Package" link.

Don't forget to set your public key on your "My Account" menu.

After that you can clone the repository, see "Git Clone URL" on the first line of the package, edit and reupload:

git clone ssh://aur@aur.archlinux.org/bla.git
# do some changes on PKGBUILD
git add .
git commit -m 'updated bla package to version X'
git push origin master

Done :3 you have successfully adopt and maintain a package :3

Best Golang IDE: IntelliJ and VSCode

I've been using IntelliJ + go-lang-idea-plugin for years now (because it's currently the best one for almost everything: Ruby, PHP, Python, Javascript, SQL, you name it..), previously it's ok to use SublimeText + GoSublime, or LiteIDE, but today we got another completely working alternative that is also purely free (like IntelliJ Community): VisualStudioCode + lukehoban.Go. Here's how to install in ArchLinux:

yaourt --needed --noconfirm -S --force visual-studio-code 
go get -u -v github.com/nsf/gocode      
go get -u -v github.com/rogpeppe/godef
go get -u -v github.com/golang/lint/golint
go get -u -v github.com/lukehoban/go-outline
go get -u -v sourcegraph.com/sqs/goreturns
go get -u -v golang.org/x/tools/cmd/gorename
go get -u -v github.com/tpng/gopkgs
go get -u -v github.com/newhook/go-symbols
go get -u -v golang.org/x/tools/cmd/guru
go get -u -v github.com/cweill/gotests/...
code

Then press Ctrl+Shift+P, type "Install Extension", type: "Go", done :3

Everything's works fine now:

In my opinion, IntelliJ still the best, but surely I'll be using VSCode when my IntellJ license ends.

Techempower Framework Benchmark Round 13

After long wait, the latest Techempower Framework Benchmark 13 is out! And just like previous one, Go's fasthttp really really fast. As usual the most important thing is data updates benchmark:

Top ranker in this part (more than 1024 req/s) are Go, C++, Java, Javascript (NodeJS), Perl, C#, Elixir, Dart, Scala, Python, Clojure, and Groovy (Actually PHP are there below the last one on the picture with 1018 req/s). And for the database part would be: PostgreSQL, MongoDB, and MySQL.
