Ski Stowe,VT 2007-04-14

Netipično za sredinu aprila, kada bi skijaška sezona trebalo da se privodi kraju, velika mećava je donela nekoliko stopi snega na severoistoku. Iskoristili smo tu priliku da odemo u Stou, naše omiljeno mesto u Vermontu. Pavle je uživao u sankanju, Saška i Laza su uživali u skijanju na svežem prahu dok je sneg vejao bez prestanka. Baka i deka su malo bili u turizmu, a više čuvali Pavla.

U povratku smo vozili 30mph po zavejanim putevima, proklizavali nebrojeno puta, i gledali proklizale automobile po jarkovima pored druma. I tako do Masačuseca gde je sneg prešao u neprestanu kišu.

Oko ponoći, na ulazu u Njujork smo naišli na neverovatnu gužvu. Radio je javljao da je naš auto put (a i mnogi drugi u okolini grada) poplavljen i zatvoren. Saška nas je ekspertski provela zaobilaznicama oko mesta gde radi, tako da smo stigli kući za 8 sati od polaska. To je bilo fenomenalno vreme, jer put u dobrim uslovima obično traje 7 sati.

Naravno, posle ponoći je gotovo nemoguće naći parking na ulici. Pravac komercijalna garaža, a kad ona popunjena. Ostale garaže u kraju ne treba ni proveravati jer su one popunjene bez izuzetka. Taman kada sam mislio da mi ništa ne preostaje nego da spavam u kolima, vidim prazno mesto na ulici odmah kod izlaza iz garaže!!! Ovo je manje verovatno nego mećava u aprilu.

Sutradan na poslu su se svi jadali da su im kuće poplavljene. Živeti u stanu na vrhu brda ima svojih prednosti.

Win32 Registry For Ruby Gems

When creating and Ruby gems under Win32, it is convenient to double-click .gemspec file in order to build the gem. And, in the same manner, double-clicking .gem file should install the gem. Registry entries below achieve just that:

Windows Registry Editor Version 5.00


[HKEY_CLASSES_ROOT\.gemspec]
@="rubygemspec"

[HKEY_CLASSES_ROOT\.gemspec\ShellNew]
"NullFile"=""


[HKEY_CLASSES_ROOT\rubygemspec]
@="Ruby Gem Specification"

[HKEY_CLASSES_ROOT\rubygemspec\DefaultIcon]
@="C:\\Programs\\lang\\Ruby\\lib\\ruby.ico,0"

[HKEY_CLASSES_ROOT\rubygemspec\Shell]
@="Build"

[HKEY_CLASSES_ROOT\rubygemspec\Shell\Edit]

[HKEY_CLASSES_ROOT\rubygemspec\Shell\Edit\command]
@="\"C:\\Programs\\utils\\SciTE\\SciTE.exe\" \"%1\" %*"

[HKEY_CLASSES_ROOT\rubygemspec\Shell\Build]

[HKEY_CLASSES_ROOT\rubygemspec\Shell\Build\command]

Pavle apparently enjoyed the sight of flowers and trees:

Well, Pavle and Nikola were not sled riding by themsleves, but they allowed their fathers (and grandfather) to haul them up and down and around.

Skiing Lake Tahoe 2007

In early february, we went skiing to Lake Tahoe, California. This was probably the most beautiful place we have been so far. The area boasts the lake, snow-covered mountains, and curvy roads fenced by evergreens. It alse glimpses over the desert scenery of Nevada.

Awesome ski ares are Squaw Valley and Kirkwood. Heavenly is great for taking pictures and enjoying groomed trails. The snow conditions were less than perfect. When we got there, the locals complained of the worst season they remember and some trails were closed. Towards the end of the week we got a few feet of snow. I wished I could ski deep powder. We also scraped our skis while going over sharp rocks covered with 3 feet of soft powder.

Anyway, a few pictures are available.

#
# with() - Equivalent of Pascal or VB 'WITH'
#
# Instead of writing ...
#       a.width = 1
#       a.height= 2
#       a.name  = "hello"
# ... write
#       with(a){
#           width = 1
#           height= 2
#           name  = "hello"
#       }
#
# Another example:
#
#    class A
#        def method_missing(name, *args)
#            puts "caught: #{name}(#{args.map{|x| x.to_s}.join(',')})"

Change Filename Extension

Below is a utility that I find myself using very often for batch scripts which read an input file, and save the output to files with same filename but different extension (e.g. "file.log" -> "file.csv")

#
# filename_change_extension "/dir/file.txt", ".CSV"
# => "/dir/file.CSV"
#
# filename_change_extension "/dir/file",     ".CSV"
# => "/dir/file.CSV"
#

def filename_change_extension( filename, extension )
    filename =~ /(.*[\/\\])?    # match the path, up to the last slash
        ([^\/\\]+)              # match the filename (no slashes)
        $                       # up to the end of string
        /x                      # remove comments from regexp
    path, name = ($1 || ""), $2 # if no path given, use "" instead of nil
    ext      = File.extname(name)
    basename = File.basename(name, ext )
    
    return path + basename + extension 
end


if __FILE__ == $0

    require "test/unit"
    
    class TestFilenameChangeExtension < Test::Unit::TestCase
        def test_1
            test_cases = [
                [   "filename",               ".c" , "filename.c"],
                [   ".filename",              ".c" , ".filename.c"],
                [   ".a.b.c.ext",             ".c" , ".a.b.c.c"],
                [   "filename.ext",           "s"  , "filenames"],
                [   "filename.ext",           ""   , "filename"],
                [   "/dir/dir2/filename.txt", ".c" , "/dir/dir2/filename.c"],
                [   "/dir/dir2/filename",     ".c" , "/dir/dir2/filename.c"],
                [   "/dir/dir2/.filename",    ".c" , "/dir/dir2/.filename.c"],
                [   "/dir2.with.dot/filename",".c" , "/dir2.with.dot/filename.c"],
            ]
    
            test_cases.each{|filename, extension, expected|
                assert_equal expected, filename_change_extension( filename, extension) , 
                             "test case [#{filename.inspect}, #{extension.inspect}]" 
            }
        end
    end
