Beautiful and Functional English Writing Software

These days I am concentrated in improving my English skill; particularly in listening and writing. Actually now I'm under increasing pressure because the score of the result of my last TOEFL exam was bad rather than insufficient. So I decided not to code programs too much as my hobby, but to write English essays more and more. I have less time to do all things what I like than usual.

To write English essays more efficiently, I wish such editors:

  • Beautiful rendering with proportional fonts
  • Rich functionalities

When I mentioned about "rich functionalities" in the context of text editing, it stands for Vim. But unfortunately Vim doesn't support proportional fonts but supports only monospaced fonts. Monospaced fonts are beautiful in programming languages, but in natural English language, they aren't.

So I wrote a patch for supporting proportional fonts on MacVim.

1

Building MacVim with my patch

First of all, fetch the MacVim source and build plain Vim.

$ git clone git://repo.or.cz/MacVim.git MacVimUjihisa
$ cd MacVimUjihisa/src
$ ./configure --enable-gui=macvim
$ make

Create the following patch file on a.patch:

Then apply it:

$ patch -p2 < a.patch
$ xcodebuild

Then run it:

$ open build/Release/MacVim.app

Then fix its font config.

Known Bugs

  • In insert mode, the location of cursor is far from correct location.
    • a
  • Vertical split is broken.
    • b
  • Handling screenwidth. Now Vim wraps in a strange position.

Now I don't have time to fix the problems.

What's the Difference Between Rip and Bundler?

In the Rip mailing list, defunkt says:

Bundler is for installing gems. Rip is for managing your load path and installed packages.

Rip isn't yet ready to manage your deployments, whereas I think bundler is.

This short answer could be helpful.

How To Skim Long Sentences Quickly

How can non-English speaking people skim long sentences quickly? Today I saw the light with the hack:

One way to increase your comprehension is to ignore all the extra words in a sentence -- trim the fat.

-- Cracking the TOEFL iBT 2008 edition

It could applied for only formal sentences.

To examine how it works, let me demo with the following sentences:

The Leland Stanford Junior University, commonly referred to as Stanford University or Stanford, is a private research university located in Stanford, California, United States. The university was founded in 1885 by United States Senator and former California governor Leland Stanford and his wife, Jane Lathrop Stanford, as a memorial to their son Leland Stanford Jr., who died of typhoid in Italy a few weeks before his 16th birthday. The Stanfords used their farm lands in Palo Alto to establish the university hoping to create a large institution of higher education in California.

Stanford enrolls about 6,700 undergraduate and about 8,000 graduate students from the United States and around the world every year. The university is divided into a number of schools such as the Stanford Business School, Stanford Law School, Stanford School of Medicine, and Stanford School of Engineering. The university is in Silicon Valley, and its alumni have founded companies including Nike, Hewlett-Packard, Electronic Arts, Sun Microsystems, Nvidia, Yahoo!, Cisco Systems, Silicon Graphics and Google.

The USNWR ranked Stanford's undergraduate program fourth in the nation, and Stanford is consistently ranked high in other college and university rankings. Stanford is one of two private universities that compete in the Pacific-10 Conference. Stanford's main athletic rival is Cal, and the two schools meet annually in the Big Game, a football game in which the winner is awarded the Stanford Axe.

-- http://en.wikipedia.org/wiki/Stanford_University

They become the followings:

  • The Leland Stanford Junior University is a private research university. The university was founded. The Stanfords used their farm lands.
  • Stanford enrolls. The university is divided. The university is. Its alumni have founded companies.
  • The USNWR ranked. Stanford is ranked. Stanford is one of two private universities. Stanford's main athletic rival is Cal.

Of course the fat part which is eliminated is also important for understanding what the sentences are stating, but it doesn't base the structure.

I thought skimming English sentences meant that just see each word flatly and quickly, but it was wrong. It is important for particularly non-English speaking people to catch only the important parts, in this case which are Subject, Verb and Object in each sentences.

Mac OS X Desktop Application Development with Ruby

takao7 published a book "Mac OS X Desktop Application Development with Ruby" (『RubyによるMac OS Xデスクトップアプリケーション開発入門』) I am interested in developing OS X local applications with Ruby very much. #RHCBK

This book is written in Japanese, but I think somebody will translate it to English.

I'm also interested the abbreviation name of this book's title RHC. The title reminds rubyists the Ruby Bible RHG: Ruby Hacking Guide by Minero Aoki.

Git Lessons Learned For Speedup

TOPIC: To know whether we can push or not without doing pull.

git status isn't reliable for this purpose. Even if the result was the following, it doesn't mean we can push without pull. The current branch may be outdated with origin's.

# On branch master
nothing to commit (working directory clean)

git ls-remote origin master is also not. Once we committed, the sha1 is already changed, therefore we cannot compare it to remote's.

So, although this has side effects, git fetch is the best solution for this problem. Doing git fetch periodically on background, and then checking git status is fast and easy way.

In short,

$ ruby -e 'loop { `git fetch` }'

In another shell.

Summary: Haskell in the Real World

I read a paper.

Curt Sampson "Experience Report: Haskell in the Real World Writing a Commercial Program in Haskell", draft of submission to ICFP 2009

This paper is not for theoretical purpose but for practical one even though the title includes the purely functional language Haskell.

I have been using Haskell for 3 years, but for draft or experimental one, not for actual production. In contrast Curt Sampson, the author of the paper, used Haskell for production code int the real world.

The paper in short

  • Curt Sampson is an experienced Java programmer, who knows C and Ruby as well.

  • He got interested in functional programming languages due to Paul Graham indirectly.

  • He wrote a financial application in Haskell for his client in the spring of 2008, instead of in Java.

  • "We explained that, for us, switching languages every few years was a normal technology upgrade,"

  • He looked for a language which provides concise yet expressive code, so that his client can read and modify them.

  • It's important not to have to change his tool for new language; e.g. Smalltalk needs special environments.

  • He decided to use Haskell instead of OCaml or Scala, because:
    • Once he considered to use OCaml, but the syntax was not clear enough for him; Double semicolons and lack of overloaded functions mattered.
    • Once he considered to use Scala, but he got dissapointed to know that it couldn't run native code.
  • Haskell codes are readable even for non-programmers.

  • He wrote his own parser library, to offer stateful parsing with ByteString in contrary to the standard library Parsec.

  • Haskell needs fewer lines of test code than Ruby.

  • Haskell is more portable than C++ even when his application involved interfacing with the Microsoft products. GHC has a good FFI.

  • Lazy evaluation causes two problems, threads and space leaks. GHC's profiler helps solving the problems, but not enough.

Conclusion: Haskell is the ultimate language.
