Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

parse "lsmod" output to "dot" format and pass it to "display". Without perl!

Know a better way?

If you can do better, submit your command here.

What others think

Wonderful.

"Imagemagick is smarter than you think. It can display dot files, so the dot command is unnecessary."

Comment by bandie91 247 weeks and 4 days ago

So how would you do this with ImageMagick?

Comment by SuperFly 247 weeks and 3 days ago

If anyone's running into a missing helvetica error on debian or ubuntu, give this a try:

sudo apt-get install xfs xfstt t1-xfree86-nonfree ttf-xfree86-nonfree ttf-xfree86-nonfree-syriac xfonts-75dpi xfonts-100dpi

and reboot.

Comment by psykotron 247 weeks and 3 days ago

SuperFly: lsmod | perl -e 'print "digraph \"lsmod\" {";;while(){@_=split/\s+/; print "\"$_[0]\" -> \"$_\"\n" for split/,/,$_[3]}print "}"' | display -

you can also replace 'display - ' with 'gm display - ' if you have GraphicsMagick installed instead of ImageMagick (or just install graphicsmagick-imagemagick-compat to replace GraphicsMagick completely)

Comment by psykotron 247 weeks and 3 days ago

@SuperFly: with IM not the whole procedure, just the `dot | display' thing. `display' can interpret this format too and displays it on transparent (for me).

@psykotron: i think reboot unneccessary. Run `fc-cache -r' !

Comment by bandie91 247 weeks and 3 days ago

I have ImageMagick-6.2.8.0-4.el5_5.3.x86_64 installed and I get this:

lsmod | perl -e 'print "digraph \"lsmod\" {";<>;while(<>){@_=split/\s+/; print "\"$_[0]\" -> \"$_\"\n" for split/,/,$_[3]}print "}"' | display -

display: no decode delegate for this image format `/tmp/magick-XX6QuBzg'.

type `display -list format' to get supported formata.

"Casually ? if you are a starter with tweed then it is recommended to start with plain variety of tweed. You can wear a tweed jacket with dark blue jeans and high boots. Incorporate a neutral t-shirt or a winter shirt under the jacket.

At work ? Tweed suit in London are quite popular as one of the formal attires. Heavy woven tweeds can make you look older, so try buying tweed suits in London that are finely weaved and pair it with your regular shirts like white or blue with smart formal shoes. Believe it or not, it can win you praise at work.

Accessorise ? Apart from wearing tweed suits in London as attire you can even use accessories made out of tweed. Tweed caps, laptop bags, scarves, gloves are a smart way to incorporate tweed in your winter collection. It is also a safe way of using tweed fabric if you are not too comfortable wearing it. There is even footwear that has tweed as their centre fabric and looks awesome.

Taking care of Tweed

Though the fabric boasts itself about being tough and rugged, it still requires a good care to use it for coming years as well. Due to its weave structure it often pick up dirt and stains that can get hard to remove. Make sure you take your tweed clothes for dry cleaning as washing them in washing machines can make them shrink. Also, keep them in cool dry place so that they do not get attracted by moths.
