factor listener change font size

I am using 0.94 (http://builds.factorcode.org/release?os=linux&cpu=x86.64 )

To change listener's font size:

Juniper VPN on Archlinux 64 bit.

mainly, follow this:
http://www.rz.uni-karlsruhe.de/~iwr91/juniper/

~/.juniper_networks/network_connect/config/foo.conf

host=vpn.your.host.com

user=your.user.name

realm=view source on the vpn welcome page and search for realm

cafile=/etc/ssl/certs/ca.pem

certfile=

Then, you can do

$ sudo vim /etc/pacman.conf

And, uncomment

[multilib]

Include = /etc/pacman.d/mirrorlist

$ sudo pacman -Sy lib32-glibc lib32-zlib lib32-nss lib32-gcc-libs net-tools

$ jnc --nox foo

$ sudo vim /etc/resolve.conf

And change nameserver order.

archbang testing

I bought a laptop because desktop's harddisk broke.

It turned out I had a working harddisk. Archbang is installed on the desktop.
The desktop PC is a6114x .

The default font, Deja Vu Mono did not display underscore character. Seems like that font isn't good. pacman -S ttf-inconsolata
$ grep font ~/.Xdefaults

$ grep font ~/.gvimrc
set guifont=Inconsolata\ Medium\ 16

I need to install VirtualBox.

Tried libevent2 libevent-2.0.13-stable.tar.gz

Les Paul Encoding

#tune=

The data has the format:


can be 0 or 1. 

If is 0, is 4 bits.

If is 1, is 10 bits.

can be 0 or 1.

If is 0, is 5 bits.

If is 1, is 20 bits.

So, the maximum datagram, word, chunk, or whatever is 32 bits. The smallest chunk is 11 bits.

There are 10 notes. And their values are (lowest note to the highest):
2, 6, 3, 0, 7, 1, 8, 4, 9, 5
do, re, mi, fa, sol, la, ti, do, re, mi.

For a monophonic chunk ( is 0), is 4 bits but reversed.
For example, for ti (value is 8 base 10), it is 0001, not 1000.

For a polyphonic chunk ( is 1), is 10 bits. NOT reversed.
For example, for fa, la, do (0, 1, 4 base 10),  it is 1100100000   (index 0, 1, 4 are set).

is always reversed. It could be 5 bits (less than 32) or 20 bits.
Probably the unit is 1/10 milliseconds..

TODO: write a program that actually demonstrates this.

how flash ads get your cookie

A Flash advertisement, hosted on http://ad.com/ad.swf, displayed on http://yoursite.com, can get cookie and send it to ad.com.

Example setup: http://pastehtml.com/view/1dntfa4.html

A swf is hosted on dl.dropbox.com. And it gets document.cookie of pastehtml.com and sends it to dl.dropbox.com.

The swf is using ExternalInterface.call() to execute arbitrary javascript.
This technique is explained here:
http://lcamtuf.blogspot.com/2011/03/other-reason-to-beware-of.html

Code:


So, you can execute arbitrary javascript by passing a string to ExternalInterface.call():

"\\"));    YOUR SCRIPT HERE      }catch(e){}//"" 

And, you can do cross domain xhr using swf (only to the domain where swf is hosted at).

Setting Node properties using SlingPostServlet

SlingPostServlet is handy


To have a multi-value property that has one value, use propname@TypeHint

curl -u admin:admin -F'foo=bar' -F'foo@TypeHint=String[]' http://localhost:8888/some/path

reading extjs docs locally

1. download extjs
2. unzip the file
3. cd extjs-3.1.1/docs
4. python -m SimpleHTTPServer 8080
5. http://localhost:8080

or, download Twisted and  twistd -n web --port=8080 --path=.

ats on windows

to install ats on windows, you need cygwin.

in cygwin you need:

• g++
• make
• gmp
• maybe automake

then,

cd ats-x.x.x
./configure --prefix=/cygdrive/c/opt/ats
make

before make install, you need to modify Makefile.

• find install: target
• quote cd "$(abstopsrcdir)" && ..

and in ~/.bashrc, you need something like:

OPT_DIR=/cygdrive/c/home/opt
export ATSHOME="${OPT_DIR}/ats/lib/ats-anairiats-0.2.2"
export ATSHOMERELOC="ATS-0.2.2"
export PATH="$ATSHOME/bin:$PATH"

and atscc is available

lua readline tab completion

#!/bin/bash

LUA_PATH="$LUA_PATH;$LUA_HOME/?.lua" LUA_CPATH="$LUA_CPATH;$LUA_HOME/?.so" "$LUA_HOME/bin/lua" -lreadline -lcomplete $*

where readline and complete are from  http://lua-users.org/wiki/CompleteWithReadline

use readline.c and complete.lua. You don't have to patch lua.c.

read http://www.lua.org/manual/5.1/manual.html#pdf-package.loaders to know how to use LUA_PATH and LUA_CPATH. question mark (?) in LUA_PATH or LUA_CPATH is replaced with foo when you do require("foo"). And, when you do require("foo.bar"),  it searches for foo/bar.lua or foo/bar.so if LUA_(C)PATH.

LLVM build on MinGW

building llvm-2.6

1. download and install MinGW
2. download and install cmake
3. download llvm
4. tar xvzf llvm-2.6.tar.gz
5. mkdir llvm-cmake
6. cd llvm-cmake
7. cmake -G "MinGW Makefiles" ..\llvm-2.6
8. it'll fail
9. open CMakeCache.txt
10. write CMAKE_C_COMPILER_ENVVAR:FILEPATH=C:/MinGW/bin/gcc.exe
11. cmake -G "MinGW Makefiles" ..\llvm-2.6
12. mingw32-make

For llvm 2.7,

1. unzip llvm-2.7
2. unzip clang source under llvm-27/tools/clang
3. cd llvm-cmake
4. cmake -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX="/home/opt/llvm" ..\llvm-2.7
5. mingw32-make DESTDIR=C: install

v8 on mingw

1. install python
2. install scons
3. install svn
4. checkout v8 svn checkout http://v8.googlecode.com/svn/trunk/ v8
5. edit Sconstruct and comment out -Werror (maybe there's a way to disable it from command line) vim v8/SConstruct
6. cd v8
7. scons
8. g++ -Iinclude samples\shell.cc libv8.a -lwinmm -lws2_32 -o v8.exe

windows batch file to convert videos to mp3

save this as tomp3.bat

@echo off

setlocal

set filename=%~n1
set filepath=%~df1
set dirname=%~dp1
set dumpfile=%dirname%\audiodump.wav
set outfile=%dirname%\%filename%.mp3
mplayer -ao pcm:fast -af volnorm -vo null -vc null "%filepath%" -dumpfile "%dumpfile%"

del "%dumpfile%"
pause

and drag and drop the movie to the batch file

clojure tab completion on windows

windows sucks because it does.

so, clji.bat:

@echo off
setlocal
set CLOJURE_HOME=%~dp0\clojure
set CLASS_PATH=%CLOJURE_HOME%\jline-0.9.94.jar;%CLOJURE_HOME%\clojure.jar;%CLOJURE_HOME%\clojure-contrib.jar
java -Djline.words="%CLOJURE_HOME%\all_names.txt" -cp "%CLASS_PATH%" jline.ConsoleRunner clojure.main %*
endlocal

clj.bat:

@echo off
setlocal
set CLOJURE_HOME=%~dp0\clojure
set CLASS_PATH=%CLOJURE_HOME%\jline-0.9.94.jar;%CLOJURE_HOME%\clojure.jar;%CLOJURE_HOME%\clojure-contrib.jar
IF (%1)==() (
    java -Djline.words="%CLOJURE_HOME%\all_names.txt" -cp "%CLASS_PATH%" jline.ConsoleRunner clojure.main
) ELSE (
    java -Djline.words="%CLOJURE_HOME%\all_names.txt" -cp "%CLASS_PATH%" clojure.main %1 -- %*
)
endlocal

clji.bat always starts repl. clj.bat starts repl when no argument is passed. otherwise, it runs the first argument (should be .clj script). it expects there's clojure/ directory at the same level of the batch files. the directory should have some jar files (clojure.jar, clojure-contrib.jar, jline..) and also clojure/ contains allnames.txt that is generated by allnames.clj:

(def all-names (concat (map (fn [p] (keys (ns-publics (find-ns p))))
    '(clojure.core clojure.set clojure.xml clojure.zip))))

(println (apply str
    (interleave (reduce concat all-names)
                (repeat "\n"))))

to run it:

$ clj all_names.clj > all_names.txt

now, modified ConsoleRunner.java (from http://jline.sf.net) that'll actually use all_names.txt:

if -Djline.words=path/to/file/that/has/word/list is passed, it'll use that file to do tab completion. it's quick and dirty. i don't get how jline works. somehow, i had to pass completor (new MultiCompletor(...)) twice to ArgumentCompletor so that tab completion works into middle of line. Also, SExpr is argument delimiter that considers things other than [\w-*<>=?] a delimiter.

so, run mvn package to build jline jar. then put jline jar file under clojure/. then clj.bat and clji.bat would work.

i always spend time to set up development environment then lose interest :P
