Instalar Ubuntu sin CDs, DVDs ni dispositivos USB utilizando �nicamente la red (PXE)

by Marcos Abel | 1 day ago | Read more

El título ha quedado un poco largo, pero eso es exactamente lo que acabo de hacer hace un rato, y como me parece algo interesante, voy a explicar brevemente cómo conseguirlo.

La base del proceso es PXE, que para definirlo en pocas palabras viene a ser un "modo de arrancar un ordenador" utilizando para ello únicamente el interfáz de red. Como podéis ver en el enlace a la wikipedia, PXE es básicamente una mezcla de DHCP y TFTP.

Paso 1: el ordenador ha de ser capaz de arrancar desde la red

Para poder instalar nuestro sistema utilizando esta tática, es necesario que éste sea capaz de hacer el boot desde un dispositivo de red. La mayoría de los PCs soportan esta característica, por lo que no debería de ser un requisito difícil de satisfacer. Una vez que nos aseguremos de que el PC "sabe arrancar desde la red", ya solo nos falta instalar un servidor que le responda adecuadamente a sus peticiones.

Paso 2: instalar el servidor

En este caso, el ordenador que va a servir los ficheros de arranque es un humilde PC con windows ya instalado, por lo que la herramienta que utilizaremos es TFTPD32. Esta herramienta es una de esas pequeñas joyas que a cambio de muy pocos KB son capaces de hacer un montón de cosas, como podéis observar en la página del autor.

Una vez descargado el programa, ponerlo a funcionar es tan simple como crear una carpeta, digamos que c:\tftp y copiar en ella el fichero tftpd32.exe. Lo ejecutamos y ya tenemos el servidor andando. Así de fácil.

Paso 3: descargarse la imagen de ubuntu peparada para estas labores

El siguiente paso será descargarse la imagen de ubuntu lista para ser servida utilizando PXE. Para conseguir este objetivo tendremos que descargarnos la carpeta ubuntu-installer que podremos encontrar en el respositorio de ubuntu. En mi caso particular, esta carpeta podía descargarse de:

ftp://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images

Paso 4: configurar el servidor

Una vez descargada esta carpeta, deberemos de copiarla en c:\tftp. Además, debemos de asegurarnos de:

copiar a c:\tftp la carpeta pxelinux.cfg desde ubuntu-installer/i386/
copiar a c:\tftp el fichero pxelinux.0 desde ubuntu-installer/i386/

Ahora ya podemos configurar el tftpd32. En la pestaña DHCP, deberemos poner 'pxelinux.0' en el campo boot file y deberemos rellenar el resto de valores ajustándose a la realidad de nuestra red. Es importante que el valor del campo 'IP pool starting address' sea una IP válida en nuestra red y que se refiera a un rango de IPs no utilizado en la misma. Una vez cubiertos todos los campos, pulsamos save y ya tenemos nuestro servidor configurado. Así de fácil,

Paso 5: arrancar el pc que queremos instalar

Con nuestro servidor perfectamente configurado, ya podemos arrancar el pc en el que queremos instalar ubuntu. Si todo va bien y los cables están bien enchufados, podremos ver que comienzan a aparecer entradas en la pestaña 'Log viewer' de tftpd32. Se establece la comunicación entre el PC que arranca utilizando PXE y nuestro servidor. Al cabo de unos instantes, el PC que está tratando de arrancar acaba recibiendo por TFTP la imagen de instalación basada en red de ubuntu. A partir de ahi sólo nos queda continuar con una instalación basada en red de lo más normal, (lenta), y aburrida.

Rails: 在MacBook上尝试Passenger(mod_rails)

自打换了MacBook以后,安装前端web服务器不在像Ubuntu上那么简单,一个apt-get就轻松搞定,不过最新的Leopard自带了Apache,虽然我不喜欢Apache,不过因为是最容易得到且内置,并且一个非常有前途的项目Passenger(mod_rails)也开始支持Leopard内建的Apache了,所以决定用这一套组合来作开发.

关于Leopard内建的Apache请看这里

安装Passenger的步骤非常简单:
# 安装gems
sudo gem install passenger
# 安装apache module并配置
sudo passenger-install-apache2-module

配置过程中会根据当前系统环境自动生成apache的配置参考信息,根据这个来修改位于/etc/apache2/httpd.conf
比如,在配置文件尾部添加入下几行
LoadModule passenger_module /Library/Ruby/Gems/1.8/gems/passenger-2.0.1/ext/apache2/mod_passenger.so
PassengerRoot /Library/Ruby/Gems/1.8/gems/passenger-2.0.1
PassengerRuby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

# Turned on Name Based VirtualHosts
NameVirtualHost *

<Directory "/Users/daniel/projects/">
Order allow,deny
Allow from all
</Directory>

<VirtualHost *:80>
ServerName project1.local
DocumentRoot /Users/daniel/projects/project1/trunk/public
RailsEnv development
</VirtualHost>

然后修改/etc/hosts,添加下面这行,将project1.local映射为本机地址即可
127.0.0.1 project1.local

打开浏览器,直接访问地址http://project1.local/即可看到rails应用程序了,不用额外启动mongrel或者其他rails的continer并占用一个console的tab了,并且Apache对静态资源进行缓存,页面速度明显快了不少...

重新启动rails应用程序的方法是touch(创建)一个名为'restart.txt'的文本文件在项目的tmp目录下即可
touch tmp/restart.txt

========== 控制Apache的内存消耗 ==========
在Apache的配置文件中添加入下两行,可以有效的控制Apache的内存消耗:
RailsMaxPoolSize 3 # Never spawn more than three processes
RailsPoolIdleTime 180 # Despawn a process when it has been idle for 180 seconds

What You're Doing is Not New, Not Revolutionary

by Erik Peterson | 1 day ago | Read more

In 1971, Mark Zuckerberg was negative 13 years old. The phrase "social network" would have returned awkward silences and weird stares, even amongst the savviest tech entrepreneurs. If you had said the word "Blog" people would have thought you were coughing something up. Yet, in their own weird little ways, thousands of people were social networking and blogging.

In my post Wednesday, I said:

We tend to live in our own little bubbles and think that somehow, our problems are brand new, and that they've never been solved before. Well, guess what: almost all of them have been solved before, have been solved better, and are included in almost all Unix systems out there.

I've found that this maxim is almost universally applicable to movements in technology. I've there's some big new thing, it has probably been done before, and it has probably been done better, and it was probably included in Unix.

finger is to Friendster as Friendster is to Facebook

The finger Unix program was developed in 1971 by Les Earnest. It provided a way for you to figure out what other people were up to. You'd execute the command "finger user@domain" and you'd get all sorts of useful information back: The user's phone number, how long they've been idle, how long it's been since they've checked their mail, and the contents of their .project and .plan files. Here's what it looks like if you execute "finger erik@subwindow.com":

[subwindow.com]
Login: erik                 Name: 
Directory: /home/erik                 Shell: /bin/bash
On since Sat Jul  5 14:11 (UTC) on pts/0 from c-98-242-74-4.hsd1.ga.comcast.net
   3 minutes 9 seconds idle
No mail.
Project:
Current Projects:
  -Super Secret project.  Relates to http://subwindow.com/articles/14
  -Rails plugin for managing approvals.  Was called acts_as_approved, but I think I'm renaming it.

Projects in Stasis:
  -Aloe: A long-term work in progress. Aloe (or "A-l=o.e": Assets - Liabilities = Owner's Equity) will
    be an easy-to-use online accounting system. It is designed for the small business owner that does
    not specifically have any skills in accounting. It is currently in pre-alpha.  http://aloe-acct.com/
  -Skribit: Formed as part of Startup Weekend Atlanta, I'm an ongoing contributor to this social suggestion
    engine for bloggers.  Contributions are erratic, based on the activity of those in the "Current Projects"
    section.  Others are more active than me, so the entire project is not in stasis, mind you.

Projects in Maintenance:
  -Forecaster.ws A simple and uncluttered weather information service, tailored specifically for mobile
    devices. Currently in late public beta.
  -PropertyBuilder A proposed alternative to Object#andand and the ilk. Available through the
    'gem install propertybuilder' command.
  -Zsff A parser/validator for the ZSFF feed format. Version 1.0 released as a gem and is available on
    Rubyforge or through the 'gem install zsff' command
  -Rhobbler A Last.fm / AudioScrobbler track submission tool for Rhapsody. Currently in public beta.

Plan:
Today, I'm going to have a 4th of July party/Kelly's Birtday party.  But it's on the 5th.  Because even parties
    can be fashionably late.

This week: Super-secret project continues.  On Tuesday I hope to release my approval Rails plugin.

Hmm. That looks awfully similar to some other services I use heavily. It's pretty much the amalgamation of my Facebook page, my blog, and my tweets. And this was available in 1971!

The Trouble With finger

You may be wondering "If finger was so great, how come I've never heard of it, and how come we aren't using it now?" Well, finger had a lot of problems, unfortunately. Here's my understanding of what caused the downfall of finger (Also note that I was negative 12 years old when finger was invented, and about 10 when most people stopped using it):

It depended on a doomed computing style. The only way finger really made sense was if everyone at an organization regularly logged into the same physical Unix machine. This made a ton of sense in the mainframe era, but finger's popularity was directly proportional to the popularity of the mainframe.
There were no privacy protections. finger was notorious for being used as a tool for crackers and other nefarious characters to gain information. If you fingered the root of a domain (ie: 'finger @gatech.edu'), you'd get a listing of every user in the system- their phone numbers, and what they were up to. This information is kind of sensitive to just be putting out into the ether. Subsequently, fingering was seen has kind of a rude thing to do to someone unless you knew them and had a justification for seeing what they were up to. This didn't sit well with lots of people and contributed greatly to its demise. finger had no privacy features like Facebook now has. If it did (ie: Here's who my friends/coworkers are, let them see this information. Only display this subset to other users), I think it might still be in heavy use today.
finger was a protocol, and not a platform. There was no party responsible for carrying it forward or for providing necessary upgrades. When Facebook users complained about too much information being available to the public, they instituted incredibly granular privacy controls. When finger users complained about the exact same thing, there was either nobody to complain to, or they said "Well, turn it off." So they did.

Lessons are for Hares

Of course, there's some valuable lessons to be learned here. The main one is that you should always make more of an effort to see what's been done before you. The makers of Facebook shouldn't have just learned about Friendster, but they should have made more of an effort to learn about the earlier ancestors of social networking. If they had looked for and learned about the reasons for finger's demise, they might have avoided about half of the major confrontations that they've had with their users. With a full understanding of history, you can better realize that you are not a unique butterfly, and that your idea is not really that new. You can better gain perspective and learn the lessons of your forebears. This is something that's not unique to technology. You should apply this maxim everywhere in life- especially politics.

Shaped Test Output

by Thomas Kadauke | 1 day ago | Read more

Last month I had to write some stuff that affected our whole application and therefore I had to run the full test suite several times a day and wait for it to finish every time to find out what the errors are that it displays. The output in the shape of ‘…E..F..FE..’ is usefull to get an overview of the amount of errors but unless you wait til the end you can’t get a clue as to where the error occurred.

That bugged me quite a while and finally i wrote a plugin that shapes the output much better (at least to my mind).

When you use the TestOutputShaper you get this:

AlbumTest:    ....F.F...
AlbumControllerTest:    FF......FF...
PictureTest:    FFFFFFFFFF

At that point – without knowing the actual error – you can stop the suite and run the particular test to see what is broken.

When you work with small test suites that may not be a big win, but when you have a lot of code and have it well covered by tests, it can be a huge time saver. Especially when you test for valid html your test suite can take like hours.

StarLogo 1.0

by Rodrigo Sol | 1 day ago | Read more

Quando criança, ficava digitando umas listagens de BASIC no MSX que vinha no seu manual. Não sabia o que cada comando fazia, apenas digitava para ver se acontecia alguma coisa. E nunca acontecia. Demorei uns dois anos para descobrir que depois de digitar eu tinha que dar o comando "Run" que era acionado pela tecla F4. A minha maior graça era quando a listagem digitada desenhava alguma coisa na tela, mas eram muitas horas de frustração para um quadradinho monocromático na tela.

Aos 13 por ironia, a primeira linguagem de programação que eu quase aprendi foi Python. Não foi por escolha, sem querer achei um tutorial na internet e a instalação foi fácil. Digo por ironia porque isso foi em 96 e o Visual Basic e o Delphi reinavam eu fui logo me envolver como uma linguagem dinâmica. Claro que eu não sabia o que era uma linguagem dinâmica.

Fui fazer o segundo grau técnico em informática e nessa época os tutoriais de Python já tinham acabado e eu acabei aprendendo VB. O que de certa forma foi legal porque finalmente eu entendi aqueles comandinhos do BASIC.

No primeiro ano, a disciplina que eu mais gostava era a de programação e a linguagem utilizada era LOGO. A primeira coisa que pensei quando eu vi aqueles comandos para mexer a tartaruga foi que isso era coisa para criança (e era mesmo). Tupetudo como sempre, perguntei para o professora porque é a linguagem que agente ia usar era LOGO? Estava doido para aprender C e eu ia ficar um ano fazendo uma tartaruga andar?
Pacientemente a professora me explicou que apesar da tartaruga, LOGO tinha todos os conceitos que ela gostaria de ensinar nessa disciplina cujo objetivo era apresentar uma linguagem procedural.

Aceitei a tartaruga e me divertir muito com ela. Hoje recebi um e-mail avisando que o StarLogo atingiu a maioridade. Saiu a versão 1.0. O StarLogo é uma evolução dos conceitos do LOGO para um ambiente tridimensional. Você vai ligando os blocos que se comunicam via mensagens (isso te lembra alguma coisa?) para fazer o tartaruga e um monte de outros personagem ganharem vida em um universo 3D. Essa nova versão traz um monte de novidade. Se na época do BASIC eu tivesse o LOGO talvez teria sido uma criança mais feliz! Volte a ser criança. Baixe o StarLogo e divirta-se.
