기본 도스창은 Drag도 메뉴에서 선택해야 하고 Text Copy 역시 쉽지가 않아서 Cygwin을 설치하면 rxvt를 설치한다.

Cygwin을 2002년에 사용하고 거의 사용을 안했으니 많이 바뀌었을 것 같다.

가장 눈에 띄는것이 rxvt이다 글꼴이 Monospace, Bistream Vera Sans 인지 잘은 모르겠지만 우선 맘에 든다. 기본 색상 역시 바탕은 짙은 파랑에 글자는 연한 노랑도 맘에 든다. 

C:\cygwin\cygwin.bat

@echo off
C:
chdir C:\cygwin\bin
rxvt.exe -display :0 -e /usr/bin/zsh --login -i
REM bash --login -i

#! perl
use warnings;
use strict;
use Encode;
binmode STDOUT,"utf8";
my @envthings = qw/LANG LC_COLLATE LC_CTYPE LC_MESSAGES LC_MONETARY
		   LC_NUMERIC LC_TIME LC_ALL/;
@ENV{@envthings}=('ja_JP.SJIS')x@envthings;
my $svndir = '\'//Shared/Disk/“ú–{Œê/\'';
my $svndirutf8 = decode ('shift-jis', $svndir);
my $svn = '/usr/bin/svn';
my $command = $svn.'admin create '.$svndirutf8;
print "Command to Subversion is:\n'$command'\n";
system ($command);

I've tried every possible combination of language, environment settings, and encoding for "$command". I've tried setting it to Shift-JIS, UTF-8, and every other encoding I can think of, but everything I do, I get a message back from Subversion telling me

svnadmin: Can't convert string from native encoding to 'UTF-8':

then printing the name out as munged characters. I've tried absolutely every combination I'm aware of, and still the thing refuses to convert string from what it thinks my "native encoding" is to 'UTF-8', even in the cases where I've set LANG=C it refuses to work.

I have absolutely no idea what Subversion is doing here.

        $system = "$CPAN::Config->{tar} xvf '$file'";

This fixes the problem completely on my Cygwin, and I was able to install CPAN modules again.

So What is GIT?

The supplied documentation of GIT says that:

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Here is the link for the wikipedia entry.

Where can I download GIT?

Here is the link.

Before following the given steps you will need to install cygwin on your system, and add its bin directory to the system path (so that all the cygwin commands are available from inside the command prompt).

So after installing cygwin run setup.exe inside the cygwin installation folder and make sure the following modules are installed.

1. make
2. gcc c anc c++ compilers
3. openssl-devel
4. curl-devel
5. Any other dependencies that are missing..

All these packages are located inside the Devel branch of the package tree. Required dependencies will be selected automatically.

Click next to install selected packages.

Compiling GIT form source

Untar the GIT source you downloaded using the command "tar xvzf git-1.5.5.tar.gz" .

Navigate to the untarred directory using a command prompt. Now run the "make" command inside the GIT source directory.

If it runs successfully then run "make install".

Before running the command make sure you have Perl (language) installed. You can check it by running the command:

perl -MCPAN -e 'shell'

and then running the following inside the cpan shell:

install blib

it should show no error. I am not sure if this is the best way to do this as I am not much of a Perl guy.

So as I mentioned before you need to run the following two command to make and install Perl:

   1: make

   2: make install

If these two steps complete successfully then your GIT is ready to go :). You can test this by running the "git" command. This command is located inside the "C:/cygwin/home/gaurav/bin". You might to add this folder to the system path too.

Pre-configured version

Here is a cygwin version pre-configured to compile GIT. It is installed on my system and works fine. Cygwin 1.5.25 and GIT 1.5.5 are preinstalled in this archive. Just decompress this archive under folder "C:\cygwin" and add "C:\cygwin\bin" and "C:/cygwin/home/gaurav/bin" to your system path and GIT should work form any command window.

Também temos o caso de que muitas vezes queremos um programa/ferramenta que faça uma pequena coisa para nós, mas acabamos encontrado apenas programas com vários e vários megas de tamanho.

Devido a essas dificuldades, muitos programadores, acabam criando pequenos scripts para agilizar suas atividades.

Exatamente dentro dessa filosofia, um programador da antiga Conectiva, Aurélio Marinho Jargas, criou em 2000 as Funções ZZ. Uma coleção de pequenos scripts, a princípio apenas para agilizar o trabalho da própria Conectiva. Em 2003 ele convidou o Thobias Salazar Trevisan, um colaborador assíduo para se tornar co-autor.

Hoje em dia, na sua versão 8.6, a Funções ZZ agrega 66 funções em apenas 125 kb e se tornou um utilitário que vale a pena ter instalado no seu computador.

Veja abaixo alguns exemplos.

História

If you want to build a project, using the Cygwin tool chain, that has dependencies to a third party library, you might experience a "multiple target patterns" error.

The usual procedure to do build a project that uses a third party library involves two steps.

1. Add the Includes required for compiling in the Project Properties > C/C++ General > Paths and Symbols > Includes dialog.
2. Add the library directories in the Library Search Path section of the Project Properties > C/C++ Build > Settings > Tool Settings > Cygwin C++ Linker > Libraries dialog. Then, in the Libraries section of the same dialog add all of your third party libraries.

NOTE: When adding your third party libraries be aware that you need to specify them with neither the "lib" prefix nor the extension. For example, if you have a library called libboost_regex.a, you should type in just boost_regex.a in the appropriate dialog. This is how the g++ compiler works, the Unix way.

Tools Used/Affected

• Eclipse IDE for C/C++ Developers (Eclipse Platform Ganymede (3.4.0), CDT 5.0.200806171202)
• Cygwin GCC tool chain (Make 3.81, GCC 3.4.4)

Solution

The root cause of the problem is that the Cygwin GCC tool chain expects paths to be in the unix style, but when Eclipse uses the values you specified for includes, library paths, e.t.c. to automatically generate the appropriate make files, it does not convert these values in Unix style and therefore building fails.

You are going to experience a beautiful build if you change all the paths you entered in Windows format to Unix format (e.g. C:\Cygwin\home to /home).

If you do this though, there is another shortcoming ahead, fortunately smaller than the previous one.

Because Eclipse won't recognize the Unix path style you're going to loose content assist (code completion) for the includes you specified and you'll also get a "Path Entry Problem" warning.

UPDATE: As volador pointed me out, you may use windows paths but with forward slashes.

Conclusion

Paths definition, for projects targeting the Cygwin tool chain, seems to have been problematic since long ago for the CDT environment. There's a relevant bug report that has been arround since 2005.

Please note "grep -v grep" is not be required for cygwin, but even if you retain it, it doesn't alter the behavior.

Step 1.

Open PowerShell. Run:

set-executionpolicy RemoteSigned

Step 2.

Create a directory in your user profile:

mkdir c:\users\(profile)\Documents\WindowsPowerShell

Step 3.

Navigate to the above created directory, and create a new file called "Microsoft.Powershell_profile.ps1"

Step 4.

Edit the file in Notepad:

$env:path=$env:path+";C:\cygwin\bin"

Step 5.

Include any other paths if necessary, or include other scripts and add-ons as needed. Relaunch PowerShell and varify the changes. Trying running

c:\cygwin\cygwin.bat

or more simply

bash

Voici une procédure simple qui marche qui ne marche pas encore. Les versions concernées sont celles qui sont téléchargeables à la date d'aujourd'hui (27 juin 2008)

• Installer Code::Blocks, version incluant MinGW, dans un répertoire sans espace, par exemple c:\tools
• On va avoir : Code::Blocks dans le répertoire C:\tools\CodeBlocks ; MinGW sera dans le répertoire C:\tools\CodeBlocks\MinGW
• Installer MSYS dans C:\tools également par exemple. En profiter pour installer MSYSDTK (au même endroit), ça peut servir aussi. Spécifier le bon répertoire de MinGW quand il sera demandé.
• Lancer la procédure décrite dans "docs\msw\install.txt" du répertoire WxWidgets :
  

  cd $WXWIN
  mkdir build-debug
  cd build-debug
  ../configure --with-msw --enable-debug --enable-debug_gdb --disable-shared
  make
  make install

• Configurer correctement votre projet WxWidget Code::Blocks (pour les paths). Et ça marche. Pour moi ça ne marche pas. Il doit y avoir un pépin quelque part.
• 2e essai : on ouvre le wiki de C::B et on tombe sur la page Compiling wxWidgets 2.8.6 to develop Code::Blocks et là tout s'arrange.
  

  cd $WXWIN
  cd build\msw
  mingw32-make -f makefile.gcc MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release clean
  mingw32-make -f makefile.gcc MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release

  Il semblerait que ces options de compilation soient les seules supportées par C::B

• Configurer correctement votre projet WxWidget Code::Blocks (pour les paths). Et ça marche. Bullshit. Non, ça ne marche toujours pas. Bon, il doit y avoir une ruse quelque part. Je ne vois pas la grosse dll d'ailleurs...

Petite remarque en passant, je connaissais Cygwin qui est assez efficace comme console type Linux sous Windows, mais finalement, MSYS est très bien aussi et un petit peu plus esthétique. Je ne suis pas sûr qu'elle ait autant de fonctionalités que Cygwin (entre autres concernant X) mais sinon, ça n'a vraiment pas l'air mal.

I thought, nxml-mode should be able to do this, but checking the function names provided with nxml didn'tyield anything useful as far as I could tell.  So I thought tidy should be able to do this.

For example, given this input xml, from a maven pom.xml where I purposefully de-formatted the xml:

[sourcecode language="xml"]

[/sourcecode]

I ran tidy like this:

[sourcecode language="xml"]

$ tidy -q -i -xml << EOF

Fortunately Cygwin comes to save my ass (one more time)

find /cygdrive/c | cygpath.exe --absolute --dos --file - | gawk '{ print "\"" $1 "\"" }' > list.txt

Eeeecs, these names were, are (and will be?) ugly and annonying.

If . is the source dir and we are talking about C we have...

find . -name "*.[c|h]" | xargs cat | wc -l

In Cygwin :

1) $startx (X window will appear)

In X window

1) $ssh -X user@ipname

2) $gnome-panel

Then the remote linux machine top and bottom panel will appear.

Diciamo che sono arrivato al punto di fare un "esc+dd" dal  rotolo di carta igenica notepad di win :D

Ma ritorniamo a noi, dopo che ci si abitua a vim/vi diventa seccante non poter usare tutti i vari shortcut, o mentre si scrive, o nella shell :) (e perchè no, nella realLife)

Perciò, dopo alcune ricerche, (ahimè senza l'utilizzo della parola shortcut) ho trovato vari documenti interessanti riguardante esattamente quello che volevo fare io: Implementare i comandi di vim nella shell.

Il passo per avere ciò è semplicissimo, modificate il vostro .bashrc aggiungendo:

set -o vi

enjoy.

Ontem fui no Tech Talk de MySql aqui na Globo.com, que me trouxe algumas idéias interessantes e também fomentou algumas discussões. Não vou falar muito sobre o tech talk especificamente, mas sobre uma discussão paralela.

Algumas pessoas sabem da minha preferência pelo Postgres sobre o MySql. Durante a apresentação ontem o Rafael me perguntou porque tanta gente utiliza o MySql e nem tanta gente usa o Postgres. Ele me perguntou isso porque usa o Postgres em alguns projetos e não viu vantagens em utilizar o MySql em vez do Postgres.

Bom, a resposta pra isso na minha opinião vem da diferença de estratégia. Banco por banco, sou mais o Postgres, embora eu considere que em boa parte dos casos, qualquer banco atende aos requisitos. Mas porque então o MySql ganhou bem mais adoção do que o Postgres?

Na minha opinião, o fator principal que levou a isso é que o MySql já há muito tempo oferece instalador nativo para o Windows. O MySql foi lançado em 1996 e começou com suporte apenas a Linux, mas desde 1998 permite instalação nativa no Windows. O Postgres começou como um projeto acadêmico em 1986, mas em 1996 se tornou um projeto open source com participação da comunidade de software livre. Podemos ver que nesta vertente atual de desenvolvimento, ambos estão disponíveis desde 1996. Enquanto o MySql suporta nativamente o Windows desde 1998, no Postgres isso só foi ocorrer em Janeiro de 2005, com o lançamento da versão 8.0. Anteriormente o Postgres só podia ser instalado no Windows com uso do Cygwin, que está longe de ser algo prático.

Considerando os recursos que ambos os bancos ofereceram ao longo de sua história, não restam dúvidas de que o Postgres é historicamente superior tecnicamente, e na minha opinião continua sendo. Entretanto, com a enorme quantidade de desenvolvedores que só utilizavam Windows (what a shame!), o fato de poder rodar o banco de dados na mesma máquina de desenvolvimento tornou o MySql muito mais conveniente para quem precisava de um banco de dados gratuito para suas aplicações.

Quando o Postgres lançou a versão 8.0 em Janeiro de 2005, muitos desenvolvedores já utilizavam o MySql há anos, e com isso sua adoção já estava bem grande. Neste ponto podemos ver claramente a diferença que fez uma estratégia correta. O fato de ser limitado tecnicamente em comparação com o Postgres não impactou o sucesso do MySql, porque durante muitos anos ele foi simplesmente muito mais conveniente para o desenvolvedor.

Atualmente, só vejo chances do Postgres aumentar seu sucesso se for comprado por alguma grande empresa e colocado em uma pilha de produtos interessante. Eu gosto muito do banco, e nos meus projetos pessoais ele é minha opção default. Entretanto, temo que ele nunca saia da sua abrangência atual, pelos erros na estratégia. É uma pena, devido à qualidade do projeto. Mas é muito difícil qualquer mérito técnico sobreviver a uma estratégia perdedora.

A causa di una mia disattenzione, la versione 1.0 prendeva in input 3 argomenti; mi sono ricordato dopo che il terzo argomento poteva esser ricavato automaticamente, senza alcuna interazione con l'utente (che può sempre sbagliare).
Potete scaricare adesso la versione 1.0.1 di registerimage .

I parametri da riga di comando (ho intenzione di scrivere un'interfaccia grafica al più presto) sono:

1. File .xml dell'immagine virtuale che volete aggiungere alla vostra VirtualBox;
2. File VirtualBox.xml che trovate nella cartella di installazione di VirtualBox;

Cliccando qui potrete scaricare sia i sorgenti che i binari per Windows.

Non scaricate questa versione. Scaricate l'ultima versione (la 1.0.3) qui

Per qualsiasi problema, non esitate a contattarmi!

PS: naturalmente per usare il mio programma, dovrete scaricare qualcuna delle nostre immagini!!!

We still encountered the same issues as the day before regarding the Friendster API. Fortunately, we understood the problem more as we kept editing codes and checking the results. If I am to explain our problem, it would be something like this (weird comparison coming up):

Friendster gives out two people for free to anyone who would like to develop applications. Establishing verbal communication between these two people, who are supposedly from the same country and speak the same language, are crucial in our project because it serves as the foundation. Without it, we wouldn't really be able to continue. However, due to unknown reasons, they actually aren't from the same country, much less speak the same language. It's like one is Filipino and the other is Spanish (they could probably understand each other at first because of the same origin of their language, but along the way, some things get lost in translation and communication is not established).

There were moments when I thought that I found the solution, but when I did the appropriate modifications, I realized that I was wrong. Dru and I have one final thing to check that we think would solve the problem. However, unlike our previous tries, we now required the help of Stratpoint's server. Sir Roqs helped us again by showing us the steps that we need to do to set-up the files we need on Stratpoint's server. Again, he did things kind of fast and it became difficult to follow. After his explanations, we went back to our workstations and tried to retrace the steps, starting with the installation (from the internet) of Cygwin and the required packages (which took quite a while... like, i don't know, at least 2 hours). After just a few minutes, we were summoned (summoned?) to the conference room, along with all the other Stratpoint employees, by Maam Luz. Apparently, Dr. Paco Sandejas, one of Stratpoint's managing partners, was present, and he was going to give a speech, a talk, something.

Instead of reading to us the slides he prepared, he decided to give a summary of his life story, from when he was a little kid, to his experiences as a graduate student. He wanted to encourage us listeners to pursue a degree after our undergraduate studies because, according to him, it "matures one's brain" which, again is according to him, is more important than 1.0 grades and medals and awards. I admit that it was inspiring ang thought-provoking, but...

(by the way, the talk was an hour and a half long, it's kind of difficult to remember all the details)

When I got back to my workstation, the Cygwin setup still wasn't finished. Unfortunately, there wasn't enough time left because we were going home soon. Since I arrived at 9, I got out at 6 (for the first time) with Arvin, David and Denise (also for the first time). The way home was still stressful, and the long lines and the heavy traffic still did not help.

P.S.
If our final attempt still doesn't work, I think we're in trouble...

Owe narzędzia przyszły mi z pomocą gdy potrzebowałem ściągnąć obrazki
z serwera http.

Przypadek 1

Nazwy obrazków wyglądały mniej więcej tak: nazwa_pliku(numer).gif
Numery były z zakresu 1 do 57.
Skorzystałem z jednolinijkowego polecenia w Perlu.
perl -e "for(1..57){system(\"wget domena.com/obrazki/nazwa_pliku\$_\")}"

Wykorzystując pętle for która za każdym cyklem umieszcza w zmiennej
domyślnej "$_" kolejny numer.

Przypadek 2

Ten sam serwer a inne nazewnictwo plików uniemożliwiło mi skorzystanie
z poprzedniego sposobu. Trzeba inaczej.

Ściągnąłem źródła HTML'a korzystając z wget'a. Po przez filtrację
grepem zostały mi same znaczniki img. Sed'em usunąłem wszystko poza
wnętrzem src="..." później znów Perl.

perl -e -n "system (\"wget domena.com/\$_\")" plik.txt

Gdzie w 'plik.txt' znajduje się źródła HTML'a po przeróbce.
