Last month, there was quite a bit of discussion around how URL shorteners are bad for the internet, and what we developers and users might be able to do to minimize the potential damage. One big idea was to use HTTP headers and rel(or revrel attribute has been called into service in other areas, namely in defining relationships between people (or to other sites you own or have a profile on), and in telling robots how to treat a link.

The first suggested solution to the short URL problem to get broad exposure was rev=”canonical”, which proposed that a page should define a “reverse” relationship to a given short URL. In other words… “You see that short url over there? well, I’m the canonical version of it, so nyah.” (In my head, web pages are full of attitude. This probably comes from years of having to physically subdue rowdy CSS.)

rev=canonical was picked up by several major sites, and has some traction. When I was looking into the issue myself, thinking about what I wanted to do for this site, I found an alternate recommendation that seemed to make more sense to me.

Back when I was strictly a front-end guy (meaning HTML/CSS/JavaScript, ya potty-minded sleezebags!) I had to muck around in Photoshop every day. A big part of my job was taking files—usually from people who had little to no idea how I did my job—and cutting them up into building blocks for a webpage. Over the years, I’ve seen a lot of sloppy Photoshop files, and have figured out a few things that a lot of designers apparently never seem to notice.

When I started, table-based layouts were the gold-standard, as they were really the only way of exerting any form of control over a layout, HTML-wise. Because of the way tables worked, elements in web layouts had to be sized and aligned to pixel-perfection, otherwise, things just ended up looking all screwy. Unfortunately, back then, getting pixel-perfect layouts was like winning the dollar lottery with a fifty cent ticket. (It didn’t happen, see.*) Today things are a bit better, and the rise of CSS allows for both more and easier layout control, and for a somewhat reduced requirement for pixel-perfection.

This is definitely not to say that designers should be let off the hook—if you’re executing a gridded layout, or a series of thumbnails and the edges don’t line up or the thumbnails aren’t all the same dimensions, then you’re being lazy, or sloppy, or both. The fact that Photoshop gives you fairly elegant tools to avoid these problems means that there’s really no excuse for it.

That being said, there are some things that can make a designer’s job harder. I’m planning to post a few of the Photoshop tips, tricks, and guidelines I’ve picked up as a web developer, starting with this one, dealing with a particularly annoying and quirky behavior of Photoshop’s guides.

I’m going to kick off the Linux Toolbox with a relatively simple one.

Command: alias
Purpose: create command-line shortcuts
Benefit: save time and effort by simplifying complicated, commonly-executed commands.

If you spend any time at the Linux command-line, chances are that you are going to type the same commands repeatedly. Or, there may be long or complex commands that you enter only rarely, but you don’t want to have to look up every time you need them.

Alias allows you create temporary command shortcuts within the current terminal session.
