When updating to 2.3.4 I noticed that touch is
no longer a simple ‘update :updated_at’, but a save!,
which caused some code to break
(e.g. touch`ing in after_save == loop)

Usage

User.first.touch_without_callbacks
User.touch_without_callbacks([User.first.id, User.last.id])

Install
Paste somewhere…

# Provide .touch as it was in 2.3.2, simply update the :updated_at field.
class ActiveRecord::Base
  def touch_without_callbacks
    now = Time.now.utc
    self.class.touch(id, now)
    self.updated_at = now
  end

  def self.touch_without_callbacks(ids, time=Time.now.utc)
    update_all({:updated_at=>time}, :id=>ids)
  end
end

Oh my theres a lot of Roll Deep right now. J2K’s ep earlier this year, Mangas promo, Flow Dans Mixtape, Roll Deeps “Street Anthems” (will review that later). And now Targets fourth installment in the Aim High series. I was quite happy at first when i heard Target would be releasing a new Aim High, but on closer inspection i realized i haven’t really been feeling Targets productions lately (with the possible exception of “Nightlife”). Still i thought, he’s a good Dj, should be interesting to see what he comes up with. Plus this time Danny Weed is also on board, and has actually produced most of the tracks. And though these kinds of collections don’t usually stay that long in the cd player, at least they are usually entertaining, and gives some insight to the scene.

However, after listening to this a couple of times i can honestly say there is not a single track i actually feel. Target is on some kind of RnB club vibe right now, no matter who he’s working with, be it Roll Deep or singers like Ruby or Kerry Louis. Danny Weed on the other hand, who’s always made quite tight and rigid grime, now make productions that are absolutley inflexible, no groove no swing. “Activity” is featured a couple of times, i didn’t like it that much to begin with, now i’m seriously bored with it. The showcasing of new talent isn’t very interesting either, Maxsta sounds like any younger on “East London is back, and it’s a bit depressing he’s had a chance to sell out with some boring Rnb this early in his career,  as on “The Reason” ft Kerry Louis. I actually know he’s better than this, but not here. Shifty sounds like he has a sour throath. Other than that there isn’t much to listen to. Dogzilla is sort of funny on his track. Roll Deeps “Turning” isnt really that bad.

What is this “revolution”, making slightly more boring music? Seriously.I really don’t know how this cd is made for. Who are these people who thinks normal grime is too hard but radio RnB too soft. Do they exist? Have they bought this? If you are one of them let me know, enlighten me.

適当なパッチ書きやがって過去の私め。しっかし、もう半年近く経ってるんだなー懐かしい。

改めて考えると、これ本当に困る人居るの？と疑問に思ってしまいました。なんだか興味が薄れてしまったし、例外で飛ばす以外の方法が思い浮かばないのでとりあえずほっときます。

その後 dup() しようとすると固まるんですが、なんだかその後全然関係ない fd に対する _close() でも固まってるんじゃないかという疑惑が。そして Vista や 7 ではたぶん発生しないんじゃないかという疑惑も。そこまで行かんでも、msvcrt71 なら大丈夫とかじゃなかったっけな。

もし本当にそうなら、Ruby での dup 失敗は WinXP についてはもう FATAL にしてしまったほうが良いぐらいの勢いではないでしょうか。

えーでもそれは何かいやだなあ。それだったらドキュメントに古い msvcrt.dll を使ってる人は注意、と書くぐらいのほうが個人的には好みです。だってねえ、たかだか dup で FATAL って。

面倒になってきたのでここで追跡終わり。「7買え、さもなくばIO#dup使うな」でもういいです。と思います。

Tenho recebido alguns comentários referentes ao andamento das rotinas de bancos e boletos que estávamos desenvolvendo a algum tempo atrás, então resolvi fazer um post rápido para informar a todos que o projeto está atualmente parado. O cliente com o qual estávamos trabalhando congelou o projeto e ainda não tem previsão de continuar com o desenvolvimento. Sendo assim, todo o código que desenvolvemos para a geração de boletos e guias também está congelado. Como é um código experimental, ou seja, ainda não foi efetivamente testado e homologado diretamente com nenhum banco, decidimos não divulgar nenhum código ainda.

Para quem está precisando gerar boletos em sua aplicação Rails, aconselho muito a utilização do projeto brcobranca, um plugin/gem criado pelo Kivanio Barbosa com a ajuda de alguns colaboradores (Shairon Toledo e Claudio Pozzebon), e que atualmente funciona com vários bancos diferentes (Banco do Brasil, Itaú, HSBC, Banco Real, Bradesco e Unibanco até então), além de geração direta para os formatos png, tif, jpg ou mesmo pdf.

Você pode encontrar mais informações sobre o projeto no github e também na página de exemplo, onde é possível gerar boletos de testes para todos os bancos e formatos disponíveis.

The MagLev alpha was released recently.  Before I get too far in to this post I need to make it clear that I’m not affiliated with the MagLev development team.  I’m not really even much of a Ruby interpreter hacker.  I’m a curious ruby developer that has heard some interesting things about the project and wanted to get it up and running now that it’s available.  I decided to make this post because the install and setup procedure is anything but standard.  It’s not complicated, just not what you normally would expect.

First lets get the code:

$ git clone git://github.com/MagLev/maglev.git

$ cd maglev

Great, we have the code.  Next step is to do a base install.  This installs the base libraries and GemStone which is the fabled persistence layer that MagLev has integrated.  GemStone is a object persistence layer originally built for Smalltalk.  If you haven’t ever played with Smalltalk or some of the variants (eg: Squeak) I recommend it.  It will turn your head upside down.

[Info] After you complete this upgrade and verify MagLev is working, run
  rake stwrappers
to generate the .rb files for the GemStone/Smalltalk FFI
in MAGLEV_HOME/lib/ruby/site_ruby/1.8/smalltalk/

As you can see on OS X it will build everything for 64bit which is pretty cool.  It also downloaded a bunch of support libraries and updated all of the submodules.  If you ever update the code locally you are supposed to run ‘$ ./update.sh’ to rebuild everything and get it all up and running.

Once you have it installed you should add the following lines to your .profile or .bashrc

export MAGLEV_HOME=/Users/rgarver/Sources/maglev
export PATH=$MAGLEV_HOME/bin:$PATH

You’ll need to make sure you run those lines on the command line also.  Once the environment is setup you can run ‘$ rake maglev:start’.  This command apparently boots up the core MagLev engine.

$ rake maglev:start
(in /Users/rgarver/Sources/maglev)
startstone[Info]: Starting Stone repository monitor "maglev".

Once that is started you are good to go:

一応 MinGW にも process.h に定義があるのですが、Ruby ではなぜか使われていません。thread_win32.c では、#ifdef _MSC_VER なときだけ _beginthreadex を使うように書かれています。MinGW だと何か都合悪いんでしょうか。win32.c でもわざわざ CreateThread 使ってるし。今度暇なときに調べることにします。

Comparing computer languages can usually be interesting, sometimes informative, often amusing and in lots of cases just damn annoying!

Still this recent Hacker News post about Python vs Clojure did catch my eye.

Despite the fact the author of the blog post had pulled the Python code from Project Euler the pythonista’s quite correctly cried foul because it wasn’t well written idiomatic python example and so was an unfair comparison.

There’s a lot of code out there posted on those intertubes over the years. However languages and practises evolve but unfortunately intertube posts can remain set in stone! Perl is often weighed down by its past history on the intertubes. One good way forward is just to produce more Modern Perl posts.

Anyway i digress, so moving on lets take a look at the Euler 4 – Finding Palindroms. This was the Clojure example that was put forward in the blog post:

(reduce max
    (filter #(let [s (str %)]
               (= (seq s) (reverse s)))
            (for [x (range 100 1000)
                  y (range 100 1000)]
              (* x y))))

Now in reply to this a much more idiomatic python example was provided:

print max(s for s in (x * y
    for x in range(111, 1000)
    for y in range(x, 1000))
    if list(str(s)) == list(reversed(str(s))))

This uses Python’s list comprehension. Definitely a very powerful construct. However i do find i get lost very quickly when trying to follow long nested comprehension’s

In this same Python post there is also mention of a twitter post by Yukihiro Matz, the creator of Ruby. Matz provided the following Ruby example:

p [*100..1000].product([*100..1000]).map{|x,y| x*y}.select{|s|s=s.to_s; s==s.reverse}.max

Despite being formatted for twitter (ie. one line) i found it easy to follow through the logic.

Ruby & Python are not the only languages that can produce an elegant solution! So not to be out done here is a Perl example. In fact its the exact same code repeated three times but formatted differently:

use Modern::Perl;
use List::Util q(max);

# twitter one liner
say max grep { $_ eq reverse $_ } map { my $x = $_; map { $x * $_ } 100..1000 } 100..1000;

# again in lispy style format
say
  max
    grep { $_ eq reverse $_ }
      map {
        my $x = $_;
        map { $x * $_ } 100..1000;
      } 100..1000;

# and again in my preferred more perlish alignment
say max
    grep { $_ eq reverse $_ }
    map {
        my $x = $_;
        map { $x * $_ } 100..1000;
    } 100..1000;

The perl code speaks for itself.. its wonderfully clear and succinct. Also its fast, each version runs in under a second on my machine!

/I3az/

klass == 0 じゃないと GC されて云々とか考えてたけど、実にシンプル。

そういう風に考えるとよく理解できますな。明示的か暗黙的か、という話だと、じゃあ to_str を明示的に呼んでもいいんじゃ？とか思っていました。

けっこう感銘を受けたのでコピペ。

% irb19
irb(main):001:0> class Foo;def to_s;”to_s”;end;def to_str;”to_str”;end;end
=> nil
irb(main):002:0> “#{Foo.new}”
=> “to_s”

This seems because all object shouold be embeded in “#{obj}”.

String として扱って構わないものは to_str を用意する、そうでないものでも無理やり変換できる手段として to_s を用意する、という位置づけと理解。なるほどなー。ようやっとなんかストンと来ました。

As you know, we really only post when AudioComics has news and views to share. Well, we gots some news, and den some views! Let’s start with Starstruck. Recently we had another great comicsference call with Elaine Lee, and the decision has been made to record the off-Broadway play in April. While we were originally looking at February for a recording date, keep in mind that, a) we are recording before a live audience, b) we are recording in Portland, Maine, and c) Portland, Maine gets pretty damn cold in February and nobody wants to come out in zero degree weather for anything. So it will be April, not February, and again we are looking at performances in a couple of different spaces. Moreover we will be doing a couple of performances at each venue, making the editing process that much easier in case of a flubbed line or missed SFX cue or someone forgets to turn of his motherf***ing cell phone. (Plus, if one performance is sold out, you get another chance to catch it. It’s all goooood…) When we have the dates set up and ticket prices confirmed, we’ll give you all the details. So keep watching the skies…! (Oh how freakin’ corny was that…)

Speaking of Starstruck, I would like to direct you to Tym Stevens’ blog ROCK SEX, and his tribute entry to the series, “The Big Bang of Starstruck: the Roots and Branches” of Elaine Lee and Michael Kaulta’s space opera at http://tymstevens.blogspot.com/2009/10/big-bang-of-starstruck-roots-and_08.html. It’s probably the most comprehensive piece I’ve ever read about Elaine and Michael’s masterpiece. Also, there’s not one, but two Starstruck pages on Facebook (one Groups page, one Fan page). If you’re on the ‘book, go sign up! I’m not telling you twice! Even more exciting, there’s a third page in the works co-created by AudioComics co-founder Lance Roger Axt. Worth MORE than its weight in credits!

Also, our partnership with that aforementioned indie publisher is moving along gracefully. And as they’ve already announced our collaboration(s) at San Diego Comic-Con, it’s time to announce it here. The following is the official press release in its entirety:

BLOODFIRE AUDIOCOMICS!
Bloodfire enters the realm of audio drama

July 22, 2009 (San Diego): BloodFire Studios is pleased to announce a collaborative partnership with the AudioComics Company to create adaptations of several titles as world-class audio drama. These pieces will be made available through compact disc, pay-per-MP3 downloads, and any and all other sound-transmitted means communication to the hungry masses.

Once known as “radio drama,” modern audio theatre, under the aegis of such producers as Dirk Maggs (producer and director of the final phases of Hitchhiker’s Guide to the Galaxy), Roger Gregg of Ireland’s Crazy Dog Audio, and Tom Lopez of Ruby fame, has transcended the boundaries of old time radio to become an art form for the new millennium, the grey area between stage and film where multi-million dollar movies play out in the greatest theater of all: your sick and twisted minds.

Says VP of Publishing and Co-founder Dennis Greenhill: “This is a wonderful opportunity for BloodFire Studios to extend ourselves yet again into an unconventional avenue to bring comic books to a seemingly unrelated fan base. Just one more step to world domination!” Says AudioComics co-Producer Lance Roger Axt: “What makes this such a great fit is that fact that both of our companies are constantly thinking outside the box in regards to marketing inside and outside of the comics industry. That and BloodFire  loves my Christopher Walken impersonation!” Says AudioComics co-Producers Bill Dufris and Dan Bernard: “Please don’t let Lance do his Walken. It’s scary.”

The first series of BloodFire AudioComics will be released in 2010, making BloodFire the only independent comic book publisher to have titles from their growing library presented in audio theatre format.

BloodFire Studios is an underground comic and graphic novel publisher formed in 1998 by two guys and an imaginary friend. Since that time, BFS has grown to become a group of professional artists and writers in the comic, motion picture, television, and video game industries. All united by their love of the comics medium and a penchant for sarcasm. BFS titles include the best selling Kindergoth, and the critically acclaimed titles DNA Hacker Chronicles, Intergalactic, Diary of Night, Vampyrates, and Utopiates.  BFS is also currently helping to develop several TV shows and a sequel to the 2008 indy scifi film The Gene Generation, based on the DNA Hacker Chronicles, staring Bai Ling.

AudioComics provides superior audio entertainment with its professional full-cast audio theatre adaptations of licensed and original properties from the world of comic books and graphic novels, accessible in today’s market with today’s sound. The AudioComics team is working to establish relationships with top name comic book companies, sci-fi writers, sponsors and the entertainment industry in Hollywood and New York, and to give these audio theatre pieces worldwide exposure. In addition to their partnership with BloodFire, AudioComics will be working with comics legend Elaine Lee on producing world-premiere audio plays based on her seminal series Starstruck, as well as the Starstruck spin-off for kids, The Galactic Girl Guides.

Post excelente escrito pelo André Faria Gomes. Muito bom mesmo! Podcasts sem dúvida são um dos meios mais indicados para adquirir conhecimento em tecnologia, ainda mais quando você está antenado no que Martin Fowler, Kent Beck, Rod Johnson entre outros estão falando. Retirado do andrefaria.com.

Um dos maiores problemas da sociedade moderna é a dificuldade de locomoção diária, a maioria das pessoas passa horas em seus carros, ou em meios de transporte públicos para irem de lugar a outro. Há alguns anos atrás quando morava na zona norte de São Paulo e trabalha na zona sul, essa era minha realidade. Uma vez que naquela época passar por isso era inevitável procurei formas de fazer com esse tempo pudesse de alguma forma torna-se produtivo, foi então que comecei a ouvir à podcasts.

Um dos maiores problemas da sociedade moderna é a dificuldade de locomoção diária, a maioria das pessoas passa horas em seus carros, ou em meios de transporte públicos para irem de lugar a outro. Há alguns anos atrás quando morava na zona norte de São Paulo e trabalha na zona sul, essa era minha realidade. Uma vez que naquela época passar por isso era inevitável procurei formas de fazer com esse tempo pudesse de alguma forma torna-se produtivo, foi então que comecei a ouvir à podcasts.

De acordo com a Wikipedia, Podcasting é uma forma de publicação de arquivos de mídia digital (áudio, vídeo, foto, etc.) pela Internet, através de um feed RSS, que permite aos utilizadores acompanhar a sua atualização. Assim, é possível o acompanhamento e/ou download automático do conteúdo de um podcast.

Neste post apresentarei os podcasts aos quais escuto e os episódios principais para que você ouça. Sugiro que você utilize o iTunes para inscrever-se nos podcasts e sincronizar com seu iPod.

あのメッセージになるかもしれませんね。しかしそれってどんな状況？map ならまだわかるけど。やっぱり何か外してる気がする。

If you want to comment more than one line of Ruby code, you can place them inside a:

=begin

=end

block. The thing is, =begin and =end must be at the very beginning of the line.

Example 1 – Read File and close

counter = 1
file = File.new("readfile.rb", "r")
while (line = file.gets)
    puts "#{counter}: #{line}"
    counter = counter + 1
end
file.close

Example 2 – Pass file to block

File.open("readfile.rb", "r") do |infile|
while (line = infile.gets)
    puts "#{counter}: #{line}"
    counter = counter + 1
    end
end

Example 3 – Read File with Exception Handling

counter = 1
begin
    file = File.new("readfile.rb", "r")
    while (line = file.gets)
    puts "#{counter}: #{line}"
    counter = counter + 1
end
file.close

rescue => err
    puts "Exception: #{err}"
    err
end

Modes
r – Read-only, starts at beginning of file (default mode).
r+ – Read-write, starts at beginning of file.
w – Write-only, truncates existing file to zero length or creates a new file for writing.
w+ – Read-write, truncates existing file to zero length or creates a new file for reading and writing.
a – Write-only, starts at end of file if file exists, otherwise creates a new file for writing.
a+ – Read-write, starts at end of file if file exists, otherwise creates a new file for reading and writing.

I was inspired by the popularity of Twitter* and Youtube* to create a micro-vlogging platform where videos would be limited to 30seconds. kuiq was an opportunity to become more familiar with Ruby on Rails* and was my first time leveraging a web API*.

hidden object　が出ちゃうってことは RBASIC(obj)->klass == 0なオブジェクトってことなのでしょう。それらしいのは marshal_dump() の arg->str なんでしょうが、r25189 でも r25230 でも klass == 0 な範囲は変わらないと思うんですよね。1.より2.のほうがよかったんじゃないかなあ、なんて。

あと ‘to_s’ が内部的に呼ばれてるのってあんまりないです。dir_inspect と dir_inspect はたぶん関係ないとして、rb_obj_inspect は Object#inspect 経由なので inspect 呼び出しの時点で hidden object に引っかかるだろうし、rb_convert_type や rb_obj_as_string なら TYPE(obj) == T_STRING ですぐに return するからこれも関係ない。とすると、もしかして拡張ライブラリが絡んでいるのでは？と考えてしまい、だめだわかんないや。

それはそれとして、RBASIC(obj)->klass == 0 の間に rb_io_write() が write メソッドを Ruby レベルで呼んでるように見えるんですが、これって何だかまずいような。えーと、hidden object 出すコードが書けそうな気がするけど、どうやればいいんでしょうか。うーん頭が回っていませんので後で改めて。
