Fixing Subdomain Configuration on Mediatemple DV

Categories: Administration, Software

Thursday, May 20. 2010

I recently found myself having to make some php configuration changes which are specific to a particular subdomain on my Mediatemple DV web host, and found that yet another part of subdomain setup is mildly broken out-of-the-box. This is the sort of thing that most people who need it can probably figure out for themselves, but I'm posting the solution hoping someone will find it useful.

On my DV the domain specific apache configuration is located in /var/www/vhosts/domain-name/conf/, where domain-name is of course replaced by your actual domain name. In this directory you should find at least httpd.include, and possibly vhost.conf as well. If you open httpd.include you'll find the following alarming warning at the top:

Letterpress and Bookbinding: Book Arts 101

Categories: Artworks

Sunday, May 16. 2010

I recently took a workshop titled "Book Arts 101" at Florida Atlantic University's Jaffe Center for the Book Arts, which, besides introducing us to a world I had only barely-glimpsed before, that of artist's books, taught us to dabble in those arts themselves, using the techniques of letterpress printing and hand book-binding.

After ogling the extensive collection of the Jaffe Center, we printed covers on a vintage proof press (a Vandercook 4) set with wood block type, then bound them into neat pamphlets using needle and thread. The residents of South Florida are truly lucky to have such a world-class collection at hand. I extend my thanks to John Cutrone of the Jaffe Center and Lake Worth's Convivio Bookworks for teaching this workshop and allowing us to experiment with this at-once anachronistic and up-and-coming craft.

12 Hours of Sebring, 2010

Categories: Exploits

Wednesday, March 31. 2010

On Saturday, March 20, my friend Jay Wilson and I were guests of Bell Micro at the famous 12 hour sports-car race. As always, this was an event that combined world-class endurance racing (it is probably second only to the 24 Hours of Le Mans in significance), with the following sideshows:

  • Car-show-type exhibits from some of the most interesting auto manufacturers
  • A broad range of individually-owned vintage sports and race cars in various states of repair and respectability
  • An absurd redneck carnival decorated by what can charitably be called 'folk art' and fueled by a biblical deluge of beer and tequila

Despite the absence of Audi this year, Peugeot deserves all respect for their flawless one-two victory in the LMP1 class and in the race overall, which makes them the first French manufacturer to ever win at Sebring — that Tricolor on the grandstands will certainly stand out at the end of a long line of German and Italian flags! Congratulations (and enthusiastic thanks for inviting us!) are also due to Bell Micro for once again finishing on the the podium, this time in third place in the GT2 class with the Rahal-Letterman BMW M3.

Thirty Stories of Demolition in West Palm Beach

This building at 1515 Flagler Drive has been a bit of an eyesore since it took hurricane damage in 2004. It was brought down with explosives on Sunday, the third tallest building to ever be demolished so in the United States. And I was lucky enough to be there!

I set up my Canon G6 on multiple-shot mode for this—it did pretty well, especially given that I was just holding it above my head in the tightly-packed crowd.

Inkscape Criticism

Categories: Design, Software

Wednesday, September 16. 2009

First, let me preface this tale of User-Interface Woe with a disclaimer: I am far from an Adobe fanboy. I love open-source software. And of course, like everyone else, I really hate Adobe's prices. But I've learned to use Illustrator and Photoshop pretty well, so now, of course, switching to anything else causes work not-so-much to grind to a halt as to slam into a brick wall while I figure out all of the different metaphors, keyboard shortcuts, and little tricks I need to approach anything like my former productivity.

Trust me, I yearn to cast aside all Adobe products! Which brings me to Inkscape, the open-source vector illustration program. I really, really want to like it as a replacement for Adobe Illustrator. It's one of those open-source apps I install every couple of years to see if it's There Yet. And, yet again, I'm starting to think that it's not. Which brings me to the first problem I encountered on my most recent attempt at mastering Inkscape.

The Italian Renaissance: an MMO I'd Like to Play

Categories: Good Ideas

Sunday, August 9. 2009

Picture it with me: an MMO based in the Italian Renaissance. Races could correspond to the various city-states of Italy, or to foreign nations, perhaps. Play as:

  • Merchants (sea voyages out of Venice, perhaps?)
  • Unscrupulous churchmen
  • Stiletto-armed assassins
  • Scheming Medicis
  • Your typical painter-sculptor-scientist-architect renaissance genius (should be a epic roll, this!)

Imagine riding into battle atop some Leonardo-designed war machine! Fencing with rapiers! Imagine going on quests:

  • Steal the head of John the Baptist for the glory of Florence
  • Dissect executed prisoners to level up in Anatomy
  • Bring back exotic goods from around the Mediterranean
  • Earn yourself an equestrian statue in your city-state's palazzo with military exploits

There's something very appealing about this, at least to me. It would be just the thing to finally get me to play an MMO.

My Favorite Author ...

Categories: Media

Wednesday, July 8. 2009

is Neal Stephenson. Without a doubt! I've read all of his books save one (haven't gotten around to Zodiac yet). I devoured all three weighty volumes of his Baroque Cycle, and bought Anathem the very day it came out, which I almost never bother with for any other kind of new release—artistic, technological, or otherwise. I didn't read the Harry Potter books until years after they were published, and I own no Apple computer products at all!

So there is some empirical evidence that Neal Stephenson is my favorite author. But lately I've been dwelling on why that might be, and I think I have part of an answer. Reading his books I am constantly running into ideas and observations, clearly and artfully developed, that I've thought of before, only vaguely. I've spoken with a friend of mine, also a Neal Stephenson fan, about this, and he confirms it is so for him also. It's a thrill to see someone with real talent flesh out the sketchier, dimly-lit parts of your own mind.

This is an intellectual pleasure, of course, but there is a more primitive reason as well. It hits that "someone gets it" part of the brain, provides the sense that you are not alone, that there are other people like yourself.

This is a feeling that all humans crave, but that unusual humans experience only rarely.

My apologies for the belated post. This was my first, though I certainly hope not my last, visit to the famous endurance races; I'd like to offer my thanks to our gracious host Bell Microelectronics, sponsor of the Panoz team that took third place in the GT2 class, for making it possible.

The pictures are all the work of my cousin Torm.

Carbon Nanotubes are Made of Virtue

It's true: you can sprinkle them on anything to make it better. Some examples:

  • Structures (obviously)
  • Reverse Osmosis membranes
  • Semiconductors
  • Fuel cells
  • Solar panels
  • Scaffolds for nerve regeneration

Certain technologies seem to have this magical quality of near-universal applicability to engineering problems. They not only make possible what would have been fantasy otherwise (space elevators, in the case of nanotubes) but also have a knack of improving everything they touch, or of being applied to a breathtaking variety of already-familiar applications.

The Cobbler's Children: Now with Shoes!

Monday, May 25. 2009

I'm sure that all three of my regular readers will notice the long-in-coming change now visible at eikimartinson.com. Most of my friends are probably sick of telling me what they think of innumerable design mock-ups, so I just went ahead and implemented one of my ideas, and I'm actually happy with the results. It's not too fancy, but I think it'll get the job done.

All the pages are valid XHTML and CSS, or they should be; if there are any exceptions to that, I'm interested to hear about them. That contact page, by the way, is a new feature; I've implemented a mailer form and script for purposes of spam protection. The site is composed according to the vertical rhythm concept (click the check box in the footer to see for yourself) with a new addition of my own—a bit of javascript to maintain the rhythm across images of any possible height.

Eiki Martinson's Half Day Off

I spent some time after my training session in Denver driving around with my co-workers in the Rockies, seeing some worthwhile sights; I apologize for the pictures but all I had was a disposable camera.

Cast-Iron Tilapia

Categories: Vittles and Libations

Sunday, February 22. 2009

Nothing fancy, this; but that's okay: dinner was done and on in the table in exactly 15 minutes (disclaimer: I had to go to the supermarket, wash dishes, clean the cast-iron pan, etc—you didn't think it would really be 15 minutes, did you?). Take your tilapia fillets, add salt and pepper and squeeze out a lemon onto both sides. Meanwhile, get your well-seasoned cast iron skillet to medium-high temperature and coat the bottom with olive oil. Lay your fillets down in the pan, away from you to avoid splattering yourself with hot oil. Try to avoid flipping or moving it more than is strictly necessary as it will fall apart when it gets close to done; I'd recommend flipping with a spatula rather than tongs for the same reason.

Cook for three minutes per side, which should give it a golden-brown surface and just-barely-done center; the thinner parts of the fillet will get crispy, but that's part of the appeal. Serve with salad and rice or whatever you want. Some brown crispy bits will be left in the pan which just cry out for deglazing and making into a pan sauce, but I haven't experimented with that just yet.

I promise not to let this site become a recipe blog. I post things like this really more for my own reference (the three minutes per side number is something I tend to forget).

in the smallest of ways. I was an extra (excuse me, "Background Artist", as they like to be called now) in the Twentieth Century Fox movie Marley and Me while it was being filmed in Fort Lauderdale. Observe closely the scenes in the Sun-Sentinel offices and you might just catch a brief glimpse of the back of my head, say. If you want your money back because the movie made you cry or disappointed you, address your demands elsewhere: I just stood where they told me to stand. All I added to the picture was a handful of photons. Of course I'll still get the blu-ray disc when it comes out, if only to freeze-frame through the scenes I was in!

Giving Subdomain FTP Users Shell Access on Mediatemple DV with Plesk

Categories: Administration, Software

Sunday, October 19. 2008

I recently created a subdomain on my Mediatemple DV service, but for various reasons, I wanted to have a separate user responsible for that subdomain, with FTP and shell access. The user can be created along with the subdomain in Plesk as normally. Unlike the creation of users associated with domains, however, there is no option in Plesk to give this subdomain user shell access.

Fixing it is trivial if you have root access. Just edit /etc/passwd, find the line that starts with the username you just created, then change the last field of that line from /bin/false to /bin/bash (or whatever shell you like). This will allow you to su to the subdomain user or login via SSH, as you prefer. Easy, I know, but I noticed the option wasn't present in Plesk and well, maybe this tip will be helpful to somebody else out there.
