Fix ADB Unauthorized(Esp Windows + Wi-fi)

If you get in trouble with unauthorized device message, copy adbkey file to ~/.android 

GPT to MBR(+ext3)

My external HDD is "Seagate Backup Plus 500 GB USB 3.0"
I want to use it for NAS(dd-wrt firmed) ,  I changed it to MBR and ext3.

-> gdisk and mkfs.ext3 is best solution!

* If you want to use only data storage, you can remove reserved space which is 5% of whole disk.
sudo tune2fs -m 0 /dev/sdb1

Raspbian gitlab issue

1. bundle install fail
-> Define highest version of "therubyracer and libv8" in Gemfile, Gemfile.lock

In Gemfile

gem "therubyracer", "0.12.0"


In Gemfile.lock

therubyracer (0.12.0)
libv8 (3.16.14.3)


2. When first connect, very very very slow.
-> You must extend timeout both unicorn and nginx
-> config/unicorn.rb , /etc/nginx/nginx.conf -> timeout 3000

Raspbian locale problem on OSX

When using raspbian with ssh connect on OSX, you can see error message like belows

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

-> Just comment out "SendEnv LANG LC_*" in /etc/ssh_config on your OSX.

Cocos2d-html5 has some difference with JSB

There still some differences between JSB and Html5. For example, there are not cc.Color4B cc.RectMake in JSB, instead, you could use cc.cc4b and cc.rect for both JSB and Html5.

Javascript code completion editor compare

I want JS code completion when using model based library(like Knockout.js)
This is result of a day searching.
Maybe some of contents are wrong.
Please comment to me when you find out mistakes.

1. Eclipse
 - JSDT(Javascript Development Tools) : Can't detect modal based library
 - VJET : I don't understand how to attach javascript library

2. Netbeans
 Powerful auto completion. But it doesn't seems to be support model based library

3.  TernJS with SublimeText2

 Better. Sublime text is free and I like this editor :) But working

4. Webstorm(Intellij IDEA)

 Best. Full supports and good IDE. But it's a commercial tool.

Redmine on ArchLinux

Basically, Read Offical Site.

http://www.redmine.org/projects/redmine/wiki/RedmineInstall

If you have a trouble with paths, see archlinux wiki

https://wiki.archlinux.org/index.php/Redmine#Installation

In my case, I skipped rmagick

bundle install --without development test rmagick

In my case use thin behinds nginx

Jenkins-CI on ArchLinux via Nginx Proxy

1. pacman -S jenkin-ci
(Maybe default port is 8090, you can edit at /etc/conf.d/jenkins)

2. edit /etc/nginx/nginx.conf

server {
  listen 80;
  server_name jenkins.domain.tld;

  location / {
    proxy_pass              http://localhost:8090;
    proxy_set_header        Host $host;

    proxy_read_timeout      100;
    proxy_buffers           4 32k;
    client_max_body_size    8m;
    client_body_buffer_size 128k;

  }

NOTICE :

Objective-C Singleton

Use dispatch_once !

jqTree - Keyboard Unbind

I like jqTree. Recently it supports keyboard navigation.
But I don't want to use keyboard navigation.  And there is no option.
So I unbind manually(jQuery)

-> $(document).unbind('keydown.jqtree');

Bootstrap - Tooltip

Tooltip (+ Popover) must run via javascript code.

[Knockout.js] Watch out when using "IF" statement

Knockout.js create html dynamically. So if "IF" statement condition is not met, there is no html(dom) element.
It is different from "CSS { display:none }"( = jQuery.hide()). "
"CSS {display:none}" is just hide existing elements without spacing.

Use jsonp! (GET only) or use proxy

PHP Array Issue when using as parameter

1. PHP function passes arguments with copying

--> you can use &

ex)
function addSomeValueIntoArray(&$targetArray, $value)

2. Order of array_push when using nested array

ex)
<BAD>
$parentArray = array();
$childArray = ["foo" => bar];
array_push($parentArray, $childArray);
//Not reflected in parentArray
array_push($childArray, ["hello" => "world"]);

<Correct>
$parentArray = array();
$childArray = ["foo" => bar];
array_push($childArray, ["hello" => "world"]);
array_push($parentArray, $childArray);

TernJS - The best code completion for cocos2d-HTML5

The lack of code completion makes me crazy when developing cocos2d-HTML5.

I found TernJS helps me.

TernJS is code-analysis engine for JavaScript.

My recommendation is using TernJS with Sublime Text 2(3, or the other editor).


Tip. If you want to check JS syntax error, JSHint will help you.

Xcode 5 and LLVM Build Recommendation both iOS and OSX

- Turn On below feature for optimization

1. Enforce Strict Aliasing

YES (Default YES)

2. Link-Time Optimization(LTO)

YES (Default NO)

3. Vectorize Loops

YES (Default NO)

4. Optimization Level :

-Ofast (Default release -Os)

*Caution
  1) Do not use if your application has high level floating point precision requirement
  2) Does not enable LTO(2.)
  3) Test Carefully

--> For best performance : Two options
 -Ofast or -O3 with LTO

- Use Static Analyzer

- Warnings : Documentation Comments

Remarkable - in iOS 7 UI Transition Guide

1. Because UIWindow inherits from UIView, you can specify a tint color for the entire app by setting the window’s tint property using code like this:

window.tintColor = [UIColor purpleColor];

2.Dynamic Type Font

 use the UIFont method preferredFontForTextStyle to get a font, instead of specifying font names or sizes.

3. Imbedded Picker in table row

4. Open Quickly

Cmd + shift + O



5. Custom Code Snippets

- Adding : Just source code (hold click and) drag in to snippet panel.
- Customizing :
    1) Create Token : <# token #>
    2) Shortcut


6. Replace - Except certain result in found
