인터넷 속도 - Byte, byte,

파일 용량은 B 단위를 쓰는데, 실제로는 iB 로 쓰는게 맞다. 사람들은 이를 B로 퉁친다.
저장 장치는 B 단위를 쓰는데, (iB라고 생각하지만) 실제론 B 단위다.
전송 속도는 b 단위를 쓰는데, (iB라고 생각하지만) 실제론 b 이다.

- 파일용량
iB (IEC Binary 단위-주.) = Byte 단위 (2진 배수) = 1 Ki B = 1 Kibi Byte = 1024 Byte = 8192 bit

- 저장 장치
B (SI Decimal 단위-주.) = Byte 단위(10진 배수) = 1kB = 1 kilo Byte = 1,000 Byte = 8,000 bit

- 전송속도
b (bit 단위) = 1kb = 1 kilo bit = 1,000 bit = 1,000 / 8 bit = 125 Byte

해서, 100 Mega 인터넷은 약 11 MiB/s (소수점 이하 절삭)이다.
100 Mbps = 12.5 MBps ≒ 11.9MiBps
1 Gbps = 125 MBps ≒ 119 MiBp

* 주. iB VS. B
|----------------+-----------+-----------------+--------|
| SI Decimal (B) | value     | IEC Binary (iB) | JEDEC |
|----------------+-----------+-----------------+--------|
| kilo(k)        | 1k = kilo | Ki kibi         | K kilo |
| mega(M)        | 1k 의 2승 | Mi mebi         | M mega |
| giga(G)        | 1k 의 3승 | Gi gibi         | G giga |
| tera(T)        | 1k 의 4승 | Ti tebi         |        |
| peta           | 1k 의 5승 | Pi pebi         |        |

Upgrading Ubuntu 17.10 (Artful Aardvark) - todo

1. screenshot problem
gnome-screenshot

2. supress animation

3. Input Sources key in iBus
Chinese(Pinyin), Korean (Hangul) key not work

Upgrading Ubuntu 17.10 (Artful Aardvark) - 언어추가(Language Input)

언어추가 (한국어,중국어,러시아어,영어)
Language Support Korean, English, Chinese, Russian

> 참조(Reference)
[Settings] -> ]Region & Language] -> [Input sources]

   add input sources "Chinese (Pinyin)", Korean(Hangul), Russian
   check 'options' Keyof
a. Switch to previous source (default Shift + Super L)
b. Switch to next source (default Ctrl + shift L)

※ Ctrl + Shift meangs 'with continusouly compressed [Ctrl] key then stroke [Shift]'

--> Setup Chinese Input Method in Ubuntu 17.10 Artful
http://gangmax.me/blog/2017/10/20/setup-chinese-input-method-in-ubuntu-17-dot-10-artful/
---------
Ubuntu 17.10 Artful Aardvark is just released. A big change in this release is that it ditches Unity for Gnome. Most likely this will be part of the next LTS version “18.04”.

Here is the instructions how to setup Chinese input method in Ubuntu Artful.

1. First, go to “Language Support”, make sure the “Chinese(simplified)” or “Chinese Traditional”(or both) is installed completely.

2. Go to “Input Method”, make sure you select “ibus” as the selected user configuration. An user logout may be required.

3. Go to “Settings -> Region & Language”, in the “Input Sources” section, add the “Chinese(Pinyin)” input method.

Now you should be able to see the input method icon “en/拼” on the top left corner of the desktop. Use “Super + Space” to switch the input method as normal.
---------

※ notice fcitx users
If you are use Fcitx input method in previous, it will still remian process after upgrade but keyboard sequence will not work. Becase iBus is default settting for 17.10 Artful Aardvark.

So, use one of following 3 method.

1. change OS's defult iBus input method to Fcitx which is your old default method.

2. use iBus input method and remove Fcitx
> explicitly set to iBus in 'keyboard and language' setting, 17.10 will automatically remove fcitx process
   (it maybe different your situation)

Upgrading Ubuntu 17.10 (Artful Aardvark) - installation

1. Prepare
> backup - pass
> turn on addition cooler pan - not necessary

2. Popup Upgrade Message

3. File downloading, installation, clean up
> it takes time, if network bandwidth and computer CPU fast enought, it will take at least 30 minute.
> downloading packages

> installing files

Website mockup with Pencil Sketching

* Website mockup with Pencil Sketching

** why

I'm not a designer but I need mockup web site for desinger and other member of developer team.

- Microsoft Office is a good tool which I used more than 10 years, but it makes me tired.

- LibreOffice is a good tool sometime it crash, but since verion 5.x it stabilized. It makes feel like more than MS-Office, just kidding.

- Actually, I use Emacs. You know what it make you is somewhat fear. So, I need out of this Emacs word!

** where it came from?

*** Once it was in -> https://code.google.com/archive/p/evoluspencil/

*** Now it is one -> https://github.com/prikhi/pencil

** download
*** source and release -> https://github.com/prikhi/pencil/releases

*** homepage and nightly build -> http://pencil.evolus.vn/Downloads.html
(Firefox Extension link)

** installation guide

-> Read Readme.md https://github.com/prikhi/pencil

: Prerequisites
:
: You will need version 4 or higher of firefox to run Pencil as a
: Firefox Extension. Linux users will need version 4 or higher of either
: firefox, iceweasel or xulrunner, or version 25 or higher of
: palemoon. The Windows installer and OS X archive has everything you
: need built-in.

** browser requirement
※ (from the above)
Pencil requires browser "firefox, iceweasel, xulrunner, palemoon"

*** firefox in Ubuntu
> env. I am running firefox installed 53.0 (64-bit) on Ubuntu 17.04 in Linux(4.10.0-20-generic), which is not compatable with pencil extension.

> I can't drag & drop

(If you use nightly build firefox 55, it opted multi-thread and you can not even activate)

*** xulrunner
(If I have enough time, it's a good chice but time is always short to me.)

*** palemoon
download -> http://www.palemoon.org/

It's simple and fast, actually not far differenct. I choose it.

** install pencil with extension

download -> https://addons.mozilla.org/en-US/firefox/addon/pencil-prototyping/

* fcitx language, xim setting, Gnome Key change
[[file:img/fcitx_lang.png]]

리눅스 우분투 키 시퀀스 변경은은 2곳에서 설정하는 데,

1. 주메뉴 [시스템 설정] > Hardware [Keyboard] > [Shortcuts] 탭 > "Typing" [List Menu)
( [시스템 설정] > Hardware [Keyboard] > [Typing] 탭의 "Text Entry" 을 선택해도 된다 )
- Switch to next source: Super+Space
- Siwtch to previous source: Shift + Super +Space
[[file:img/fcitx_system_key.png]]

2. fcitx 설정에서 변경
Fcitx [Icon] 실행 혹은 Configure Fcitx [mouse light popup menu]
-> Input Method [tab]
-> Pinyin [list select]
-> Global Config [Tab]
-> Trigger Input Method [item]
change from: "Ctrl+Space" --> to "Shift+Space"
-> Scroll between Input Method: Ctrl_Shift
[[file:img/fcitx_config.png]]

3. Emacs key sequence 변경
(만약 emacs 에서 사용하는 키가 시스템에서 정의한 키와 중복될 경우 먼저 제거한다)

#+name: dot emacs
#+begin_src elisp
;; <leim> 을 사용할 경우 require (required korea-util.el and hangul.el)

SQLite Source Code Blocks in Org Mode

SQLite Source Code Blocks in Org Mode--> http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-sqlite.html

# -*- coding: utf-8 -*-
#+STARTUP: content
#+LANGUAGE: ko
#+PROPERTY: header-args:sqlite :dir ~/org/ :db journal.db :var rel="cur" :results line :colnames yes

: header arguments -> :csv, :column, :line, :list, :html
: results -> silent raw
: separator \

※ 1. File scope variable which is name "#+PROPERTY" can be located any location of file.
※ 2. "#+PROPERTY" var will be initialize when file opening time.
(therefore, if you modify "#+PROPERTY" it can be use until reopen the file again!)

* sqlite org babel

[[http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-sqlite.html][guide_from orgmode.org]]

** emacs babel setup
#+TITLE: dot
#+begin_src elisp
(org-babel-do-load-languages
'org-babel-load-languages (quote ((emacs-lisp . t)
(sqlite . t)
(R . t)
(python . t))))
#+end_src

** Org Mode Features for SQLite Source Code Blocks
Header Arguments
Language-specific default values

There are no language-specific default header arguments for SQLite.

** Language-specific header arguments
There are 11 SQLite-specific header arguments.

db
a string with the name of the file that holds the SQLite database. Babel requires this header argument.
header
if present, turn on headers in the output format. Headers are also output with the header argument :colnames yes.
echo
if present, set the SQLite dot command .echo to ON.
bail
if present, set the SQLite dot command .bail to ON.
csv
the default SQLite output format for Babel SQLite source code blocks.
column
an SQLite output format that outputs a table-like form with whitespace between columns.
html
an SQLite output format that outputs query results as simple HTML tables.
line
an SQLite output format that outputs query results with one value per line.
list
an SQLite output format that outputs query results with the separator character between fields.
separator
a string that specifies the separator character used by the SQLite `list' output mode and by the SQLite dot command .import.
nullvalue
a string to use in place of NULL values.

** Variables
It is possible to pass variables to sqlite. Variables can be of type table or scalar. Variables are defined using :var=<value> and referred in the code block as $<name>.

Table variables
Table variables are exported as a temporary csv file that can then be imported by sqlite. The actual value of the variable is the name of temporary csv file.
Scalar variables
This is a value that will replace references to variable's name. String variables should be quoted; otherwise they are considered a table variable.

** Sessions
SQLite sessions are not supported.

** Result Types
SQLite source code blocks typically return the results of a query. The header arguments :csv, :column, :line, :list, and :html determine the output format.

: #+PROPERTY: header-args:sqlite :dir ~/org/ :db org.db :results list

* sample create
: #+name: sqlite-populate-test
: #+header: :results line
: #+header: :dir ~/tmp/
: #+header: :db hello.db
: #+begin_src sqlite
: create table greeting(one varchar(10), two varchar(10));
: insert into greeting values('Hello', 'world!');
: #+end_src

#+begin_src sqlite
create table greeting(one varchar(10), two varchar(10));
insert into greeting values('Hello', 'world!');
#+end_src

* sample query
: #+name: sqlite-hello
: #+header: :list
: #+header: :separator \
: #+header: :results raw
: #+header: :dir ~/tmp/
: #+header: :db hello.db
: #+begin_src sqlite
: select * from greeting;
: #+end_src

#+begin_src sqlite
select * from greeting;
#+end_src

#+RESULTS:
| one | two |
|-------+--------|
| Hello | world! |

* Using scalar variables

** using local var.
#+BEGIN_SRC sqlite :db ~/org/journal.db :var rel="tname" n=300 :colnames yes
drop table if exists $rel;
create table $rel(n int, id int);
insert into $rel(n,id) values (1,210), (3,800);
select * from $rel where id > $n;
#+END_SRC

#+RESULTS:
| n | id |
|---+-----|
| 3 | 800 |

** usign file var.
#+BEGIN_SRC sqlite :var n=300
drop table if exists $rel;
create table $rel(n int, id int);
insert into $rel(n,id) values (1,210), (3,800);
select * from $rel where id > $n;
#+END_SRC

#+RESULTS:
| n | id |
|---+-----|
| 3 | 800 |

* Using table variables

We can also pass a table to a query. In this case, the contents of the table are exported as a csv file that can then be imported into a relation:

** local var.

#+NAME: tableexample
| id | n |
|----+----|
| 1 | 5 |
| 2 | 9 |
| 3 | 10 |
| 4 | 9 |
| 5 | 10 |

#+begin_src sqlite :db ~/org/journal.db :var orgtable=tableexample :colnames yes
drop table if exists testtable;
create table testtable(id int, n int);
.mode csv testtable
.import $orgtable testtable
select n, count(*) from testtable group by n;
#+end_src

#+RESULTS:
| n | count(*) |
|----+----------|
| 5 | 1 |
| 9 | 2 |
| 10 | 2 |

** using global file var.
#+begin_src sqlite :var orgtable=tableexample
drop table if exists testtable;
create table testtable(id int, n int);
.mode csv testtable
.import $orgtable testtable
select n, count(*) from testtable group by n;
#+end_src

#+RESULTS:
| n | count(*) |
|----+----------|
| 5 | 1 |
| 9 | 2 |
| 10 | 2 |
