OT – I’ve been doing most development on Ubuntu and OpenBSD. I recently made the mistake of ordering a fully loaded Dell Inspiron 1720, only to learn that Dell dumbed it down by replacing the DVI port with VGA and disabling the RAID support on the mother board. Instead of following Dell’s marketing plan and getting their XPS, I promptly went to Apple.com and bought a Macbook pro. I recommend development on the Macbook pro and Leopard is a great Unix development environment.

Okay, back on topic….My favorite solution to adding back the bookmark icons was a comment by klugerama in the comments of Lifehacker’s article Mac Tip: Add favicons to the Firefox bookmark toolbar

I have a feeling this will help some of y’all if you are getting the following error:

Sorry! Something is not quite right with the request we received from the website you are trying to use. Please try again in a few minutes. If this error persists, please contact the site administrator for the website you are trying to use. If you are the site administrator, click here to contact us.

I get this error if I try to login on my development environment because localhost:3000 just won’t cut it for Yahoo’s OpenID security policy. If I run from a production URL on port 80, say http://myutil.com/ then signin works (though I haven’t gotten Simple Registration Attribute Exchange working with Yahoo).

Yahoo! Security Policies Yahoo! will only support Relying Parties running on webservers with real hostnames (IP addresses are not supported) running on standard ports (Port 80 for HTTP and Port 443 for HTTPS).

Hope this saves ya some time!

Update July 16th, 2008: Sphinx sphinx-0.9.8 has been released and this port has been updated.

Here is a OpenBSD port of Sphinx, Free open-source SQL full-text search engine. Sphinx is a wonderfully fast and memory efficient deep text search engine. I have found integrates nicely with Ruby and Ruby-On-Rails.

I hope at some point to get this port committed to the OpenBSD CVS repository. In the meantime this will be the ports home. Till it hits the OpenBSDs repository, it will live in my SVN repository here.

You can download a snapshot of the source code for the port here: sphinx.tgz. So far this port has been tested with MySQL and Postgresql on OpenBSD 4.2 and OpenBSD 4.3-betaOpenBSD-4.4-beta on the i386 platform with the Ultrasphinx Ruby-On-Rails plugin.

Instructions to build the port

If your ports tree is not already prepped, please begin by prepping your ports tree.

I recently installed the raspell gem on my development box as part of an evaluation of ultrasphinx.

Unfortunately, the native extension to raspell doesn’t link in the dynamic libraries it uses. A fix is provided below.

Note, using the raspell with ultrasphinx also caused a ruby core dump, this time in an assertion from the configuration for aspell. OpenBSD uses aspell-0.50.5 and after upgrading aspell to 0.60.5, raspell started working fine.

** Starting Rails with development environment...

A little poking around and I noticed the native library, raspell.so, doesn’t link in libaspell!

A quick fix is to add the libs to extconf.rb and rebuild the library:

1. cd /usr/local/lib/ruby/gems/1.8/gems/raspell-1.1/ext
2. edit extconf.rb and add the line $LIBS = ” -lstdc+ -laspell”
3. sudo make clean
4. sudo make
5. sudo cp raspell.so ../lib/.

Thanks, I find these useful and I hope you do too. I now do all my development from a OpenBSD (patched) Desktop and have made these binaries as secure as possible. All binaries are produced behind pf firewalls.

I have a old Mac Mini I can install macppc and produce binaries…if there is a demand.

MyUtil.com was hosted on a dedicated server from 1and1. Now I’m hosting on a dedicated server from m5hosting.com. 1and1 infrastructure was excellent when I leased these servers 3 years ago and I was one of their first customers. I can’t say that now as speed on my “100Mbps” connection to all my servers had dwindled to a paltry 180K/s to the west coast.

Then the the biggest problem was 1and1’s customer service. Sure they answer the phone. But then the person who answers the phone can only send one way messages to the techs. And the techs never send information back to the customer. Right before I dumped them, I took a perfectly healthy machine and started their re-image process to do speed tests with their OS instead of mine. 36 hours and many phone calls after my box disappeared, 1and1 customer service could only say “We will check with level 2 tier support. Check back with us in another 24 hours”. Boy though, once I used their cancellation website to dump them, they had me locked out of my prepaid servers within about an hour (my choice was cancel at end of contract, or, cancel in 30-120 days. BTW, MyUtil.com should have had 0 downtime…but I wasn’t expecting “end of contract” to mean 1and1 locks you out now and keeps your money.

I have been completely satisfied with m5hosting. It is very refreshing to have a support issue in the middle of the night, and the tech helping me designed the network. Plus now my sites scream!

I wanted to prototype my Gibberish translations before we have an actual translator. I grabbed gibberish_translate and started copying and pasting from Google Language Tools.

After five minutes of this, I thought there has got to be a better way. I googled for an API to the Google tools, and though I found none, I did find a scraping Ruby API called rtranslate. So…

gem install googletranslate

  require 'rtranslate'
  def index
     # ...Mark's entire index method goes here unchanged
    if params[:filter] == "untranslated"
      count=0
      @paginated_keys.each do |key|  
        if ! @translated_messages[key]
          @translated_messages[key] = { 
          :to => Translate.t(@en_messages[key], Language::ENGLISH, session[:translation_locale] ),
          :from => @en_messages[key]
          }
        end
        break if (count += 1) == per_page
        sleep 1 # Let's be nice to google
      end
    end
  end
 # end of index from gibberish_translate's translations_controller.rb

And now Google does the work for me with the click of a mouse!

Note I did make some other changes to Mark’s code. There was a bug in translations_controller.rb in that it lost your current local when saving changes. To fix this I changed the set_translation_locale to use the session of there is no paramater:

  def set_translation_locale
    session[:translation_locale] = params[:translation_locale] if params[:translation_locale]
    session[:translation_locale] = Gibberish.languages.first if Gibberish.languages if ! session[:translation_locale]
  end

I also made some changes to gibberish_translate’s extractor.rb to handle Gibberish strings with default keys ("foo"[] is a valid Gibberish way of saying "foo"[:foo]):

    end

    def add_messages(contents, start_token, end_token)
      contents.scan(message_pattern(start_token, end_token)).each do |text, key|
        key = text.tr('[  ]', '_').downcase if ( key == '' )
        add_message(key, remove_quotes(text, end_token))
      end
    end

The final tweaks I made was to make the find system call more portable (no -regex on OpenBSD) and also have it search for strings in my gibberish_rails plugin:

1

    def files_with_messages
      `find #{dirs_to_search.join(" ")} -type f '(' -name '*rb' -or -name '*.ml' ')'`.split.map(&:chomp)
    end

    def dirs_to_search
      %w(app config lib vendor/plugins/gibberish_rails).map { |dir| "#{RAILS_ROOT}/#{dir}" }
    end

Peace!

Portions of the above code Copyright© 2007 Peter Marklund

With migrating from Rails 1 to Rails 2, I have tried to simplify. When I wanted to prototype a multilingual Rails application I was very intrigued by Gibberish and it’s simplicity.

As all Gibberish does is translate strings and all this plugin attempts to do is translate srings in Rails. This plugin is in a very early prototype stage but I expect it to be useful none the less.

If you want full localization of dates, numbers, the world etc. check out some of the other more mature localization plugins.

If you are trying to localize your Rails strings with Gibberish, then this plugin is for you.

When I set out I didn’t even expect to make a plugin, just write some simple ruby in my project. However, it turns out there is a reason for the bloat in localization plugins…rails was never designed to be localized and has some quirks that lead to the necessity of overriding large core rails methods. The rails core team is obviously aware the problem and are working on a solution with ticket 9726. I’m hoping Rails ticket 9726 will make it to edge and then I’ll be able to simplify this plugin.

Without further adieu, I give you gibberish_rails.

Here is a link to the RDoc.

Quickie instructions (includes install for Gibberish).

./script/plugin install svn://errtheblog.com/svn/plugins/gibberish
./script/plugin install http://svn.myutil.com/projects/plugins/gibberish_rails/

Please read the README in it’s entirety before using.

Now you must translate your strings. I recommend using gibberish_translate. My next article will be on automatic prototyping translations with gibberish_translate and Google Language Tools.

While nightly backups and SVN are great, sometimes we make a mistake and rm something we need back. This article should also be useful to anyone who needs to do forensic analysis of a filesystem. This technique should also work under freebsd, netbsd, linux, solaris, dos, windows, etc. just the installation part of tools would be different and you might need a -t option to dls.

I did this yesterday on my development box under the /home partition. The first thing is to try to ensure nothing overwrites the deleted inodes.

In this example /home is /dev/wd0e. You can use df to determine your setup.

shutdown  now
# or, if you are not alone and want to give peope 2 minutes:   shutdown  +2

Now that we are in single user mode, unmount the disk

umount /home

Ok, the inodes are safe. Let’s undelete them. On OpenBSD we have, The Sleuth Kit an evolution of TCT and unrm is now called dls.

sudo su
export PKG_PATH="ftp://ftp2.usa.openbsd.org/pub/OpenBSD/4.2/packages/i386" 
# or, setenv PKG_PATH "ftp://ftp2.usa.openbsd.org/pub/OpenBSD/4.2/packages/i386" 
pkg_add sleuthkit

# Now, we will need tcl for the comeforth script referenced below.  Intall if you don't have:
pkg_add tcl-8.4.7p5
ln -s  /usr/local/bin/tclsh8.4 /usr/bin/tclsh

Now my /var has lots of free space. The following command will find all deleted inodes and place them in a file.

dls  /dev/wd0e > /var/tmp/undelete.bin

You can also yous fls on the raw device to report on directory information (file names). To get information on deleted sub directories, you would need to determine which inodes are directories and then use fls on those inodes.

If it is a text or source file you are looking for, you can just use something like less to search undelete.bin now.

Otherwise, if you want to extract files, I recommend comeforth. TCT does not build correctly on OpenBSD anymore. It is possible to get enough of TCT working for lazarus to run, but comeforth is much faster.

First, download and open comeforth. Now make it executable chmod +x ~face/comeforth/comeforth. We should already have tclsh installed above so now we run comeforth which is an interactive script. I am looking for Ruby-On-Rails files under app. So first I create a file of regular expressions that will match the output of the file command for the files I want to retrieve:

echo 'ASCII' > files
echo 'HTML' >> files

Script started on Mon Jan 14 15:13:05 2008

And thats it. You now have all your deleted files in recov. You can use grep to find the specific files you want. If the arglist is too long, then break it down with find. For example, lets say you where looking for the ruby class UsersController:

find . -print | xargs -L 10000 grep "^class UsersController"

You may have to delete some nulls at the end of your files. I tried dls -b but that didn’t seem to help.

I hope this is useful to someone else out there…

Thanks to Bernd Ahlers, the official OpenBSD ruby 1.8.6-111 ports are now in the OpenBSD CVS Repository.

I have updated my post and associated binaries Ruby 1.8.6p110 on OpenBSD 4.2 to use the official 111 port instead of mine.

OpenID makes sense. Dr. Nick’s multi-OpenIDs per user example app makes even more sense.

In the middle of integrating it into my project, gem-1.0.1 came out and broke ruby-openid-1.1.4. Dr. Nick’s great example no longer worked!

A little digging and I found Dr. Nick’s example uses the standard open_id_authentication. That has a patch to work on ruby-openid-2.0.2 and rails 2 which can be found here.

So in a nutshell, I grabbed openidauth_multiopenid-0.3.2 from Dr. Nick, removed a bunch of stuff from vendor plugins. Updated Rakefile, config/boot.rb, and config/environment.rb for rails 2.0.2. Patched vendor/plugins/open_id_authentication for ruby-openid-2.0.2. Regenerated db/migration/002_add_open_id_authentication_tables.rb. And installed ruby-openid-2.0.2 as a system gem.

As a little code is worth more than a thousand words, here is Dr. Nick’s example application fully ported to rails 2.0.2 in ZIP and TAR.gz.

For my port of Dr. Nick’s example above to work, you will need rails-2.0.2 and ruby-openid-2.0.2 installed as a gems.

http://drnicwilliams.com/2007/07/26/sample-app-rails-multiple-openids-per-user/
http://dev.rubyonrails.org/ticket/10604
http://openidenabled.com/ruby-openid/
http://svn.rubyonrails.org/rails/plugins/open_id_authentication/
http://openid.net/

I started a real update to the port but was unable to complete it quickly. I have more pressing coding tasks and can’t spend the time now to complete the port.

My short term solution is to just use ruby gems to update itself (assuming you already have gem installed, if not see below).

sudo gem update --system

Then, if you want to, update some installed gems (like rails -> 2.0.2)

sudo gem update rails

I updated my systems which run my ruby-1.8.6p110 port. However it should work with the stock ruby and gem which you can install via OpenBSD ports:

sudo su
# setenv PKG_PATH "ftp://ftp2.usa.openbsd.org/pub/OpenBSD/4.2/packages/i386" 
export  PKG_PATH="ftp://ftp2.usa.openbsd.org/pub/OpenBSD/4.2/packages/i386" 
pkg_add ruby ruby-gems ruby-iconv

gem update --system

If anyone has a pointer to a completed native port, please let me know.

This article describes building a ruby port from source. If you want the binaries produced by this article, I have released them via this Rubyforge project.

If your ports tree is not already prepped, please begin by prepping your ports tree.

Now lets update the ruby port from CVS HEAD and build it. I did this on December 31, 2007 and the snapshot of the source code to the port can be found here: ruby.tgz

export CVSROOT=anoncvs@anoncvs3.usa.openbsd.org:/cvs   # pls choose a mirror near you
# setenv CVSROOT anoncvs@anoncvs3.usa.openbsd.org:/cvs

cd /usr/packages/i386/all
pkg_add ruby-1.8.6.111 
# Or, of you already have ruby installed, try:  pkg_add -r ruby-1.8.6.111

pkg_add ruby-gems ruby-iconv-1.8.6.111  mysql-server mysql-client

# Update gems to version 1.0.1, apparently needed for rails 2.0.2 but will break things like ruby-openid-1.1.4
gem update --system

gem install rails
# For Rails 1.2.6
# gem install -v 1.2.6 rails

# Now let's optimize ruby for mysql
gem install mysql

# finally, mongrel rocks
gem install mongrel --include-dependencies
gem install mongrel_cluster

If this is a new MySQL install, don’t forget to follow the instructions in /usr/local/share/doc/mysql/README.OpenBSD.

Enjoy!

This follows 15.3 – Working with ports. Here are the main steps:

Your /etc/mk.conf should look similar to this:

SUDO=/usr/bin/sudo
WRKOBJDIR=/usr/obj/ports
DISTDIR=/usr/distfiles
PACKAGE_REPOSITORY=/usr/packages
USE_SYSTRACE=Yes

sudo su
cd /usr
tar xpfz /tmp/ports.tar.gz
chgrp -R wsrc /usr/ports
find /usr/ports -type d -exec chmod g+w {} \;
mkdir -p /usr/distfiles /usr/obj/ports /usr/packages
chgrp -R wsrc /usr/distfiles /usr/obj/ports /usr/packages
chmod g+w /usr/distfiles /usr/obj/ports /usr/packages
exit

No ensure you are part of the wsrc group. You should be able to do the following as a normal user:

setenv CVSROOT "anoncvs@anoncvs3.usa.openbsd.org:/cvs" 
#or, export CVSROOT=anoncvs@anoncvs3.usa.openbsd.org:/cvs
cd /usr
cvs -q up -P -rOPENBSD_4_2 ports

Reference: 15.3 – Working with ports

I have to update several OpenBSD systems so I find it easiest to make a 4.2-current (patched) distribution. This can also be burned to a cd so new installs or upgrades via cd are also patched.

So, I have just upgraded to 4.2 OpenBSD. I am now going to build a patched distribution, patching the system in the process.

Let’s do it:

sudo su
# setenv CVSROOT "anoncvs@anoncvs3.usa.openbsd.org:/cvs" 
export CVSROOT="anoncvs@anoncvs3.usa.openbsd.org:/cvs" 
cd /usr
mv src src-4.1
# rm -rf src-4.1 &
mkdir src
cd /usr/src
tar xpfz /tmp/src.tar.gz
tar xpfz /tmp/sys.tar.gz 

cd /usr
cvs -q up -P -rOPENBSD_4_2 src 
cd src/sys/arch/i386/conf

#use GENERIC for non MP or HT servers
/usr/sbin/config GENERIC.MP
cd ../compile/GENERIC.MP
make clean && make depend && make

# if you did not do the 'set image bsd.mp' step above, then just 'make install'
rm -f /obsd.mp
ln /bsd.mp /obsd.mp
cp bsd /nbsd
mv /nbsd /bsd.mp

sync
reboot

Log back in as root after reboot, you should see the kernel now has a name like “OpenBSD 4.2-stable (GENERIC.MP) #0”. The -stable means the eratta patches where applied.

cd /usr/src
rm -rf /usr/obj/*
cd /usr/src
make obj
cd /usr/src/etc && env DESTDIR=/ make distrib-dirs
cd /usr/src
make build
# This will take a while

reboot

When the build completes, your system is up to date. If you have only 1 machine, you are done. However, I need patched distribution sets for my other boxes:

export DESTDIR=/usr/dest
export RELEASEDIR=/usr/rel
# setenv DESTDIR /usr/dest
# setenv RELEASEDIR /usr/rel
cd /usr/src/distrib/crunch && make obj depend all install
test -d ${DESTDIR} && mv ${DESTDIR} ${DESTDIR}.old && rm -rf ${DESTDIR}.old &
mkdir -p ${DESTDIR} ${RELEASEDIR}
cd /usr/src/etc
make release
cd /usr/src/distrib/sets/
sh checkflist

We now have a release in /usr/rel. I combine this with an official distribution to get the x-windows sets as I am not building them here. Basically, I copy everything except MD5 from /usr/rel into the 4.2/i386 dist dir that has everything from the ftp server except install42.iso. Then I edit the MD5 to include the new checksums. Now put everthing under a directory structure OpenBSD/4.2/i386. For this example, say it is all in /tmp/OpenBSD/4.2/i386 we can now make the iso cd image:

cd /tmp
mkhybrid -A "OpenBSD-4.2-stable-i386" -P "Me" -V  "OpenBSD-4.2-stable-i386" -r -b 4.2/i386/cdbr -c 4.2/i386/boot.catalog -o OpenBSD-4.2-Stable-i386.iso OpenBSD

Thanks!
