The attribute these web and Mac apps have in common is that they are all beautiful, simple and functional. They each perform a fairly complex task with almost no learning curve.

Yep is a PDF management program similar to iPhoto, but much more focused on meta-data.

I love the effects in Yep, the scanning interface, the simplicity and responsiveness. What a great way to get rid of paper clutter yet still be able to find something when you need it. Everything is perfect, especially that icon 🙂

Next – CSSEdit. So much has been said about it already but it’s good enough to mention again. Who would have guessed editing CSS could be pleasant?

CSSEdit’s best features are the real-time preview window and the very logically arranged panels on the right which make using the WYSIWYG functionality about as fast as typing code (minus the syntax errors and remembering the names of every selector).

Picnik is a web-based photo editor in Flash. I don’t think I could suggest a single feature to make it better. I know my way around Photoshop well, but for editing a picture from or for Flickr, I prefer Picnik for its simplicity and focus on fast and fun.

Picnik has a lot of AJAX (html/javascript) competitors that require you to wait for a new version of the image from the server after every edit. Not so here–Flash was the perfect choice. Edits are instant. Excellent.

Tumblr – Techcrunch (and everyone else really) beat me to this one, but I’ll include it anyway. Way back when I predicted the growth of Tumblelogs and alas, it has happened. Tumblr makes Tumblelogging simple and fun and they do what so many other web apps don’t–they give you all the control. From fully editable templates to an API, Tumblr does so many things right.

Even I’m doing it now (check out that URL 🙂 )!

That’s it for now, 2 web apps, 2 desktop apps, all as close to perfection as it gets.

Once you’ve learned the basics, I think the best way to learn Ruby on Rails is to look at apps written in Rails and learn from their source. The nice thing about Rails is that once you’re familiar with one application, you can pretty much open any Rails app and understand the structure enough to know where to go to look for the code that is relevant to what you’re learning.

This is a list of apps that have been helpful to me for learning.
1. Devalot – I wouldn’t have guessed it, but this is the one where I’ve found what looks to me to be the best code and some of the most interesting use of plugins. Check out the table_maker plugin in the app–it’s amazing! Devalot is DRY. If nothing else it’s a great example of DRY programming in Rails.

2. Mephisto – For one it’s written by Rick Olson who is part of the Rails core team. In fact, that’s enough in and of itself. Justin Palmer also works on it. What more needs to be said.

3. RadiantCMS – Radiant like an example of simple code that works well. Radiant is fairly easy to understand and this makes it good to learn from. One interesting thing in RadiantCMS is their use of behaviors which are based on Radius.

4. Beast – Good for learning to be concise and learning REST. Rick Olson also works on this project.

That’s it. Check ’em out.

Tonight I wanted to collaborate with a few friends on a diagram–basically just an org chart. This being the age of online collaboration, we tried all the web-based tools we could find which were:

• Thinkature
• ConceptShare
• Imagination Cubed
• Vyew

We quickly discovered that they are all lame. This is why.

Thinkature – Once we got several shapes on there I was no longer able to move things around without things jumping all over the place. It was also very limited in that you can’t cut and paste or duplicate sheets. Really this was probably the best of the bunch for what we were trying to do, but not because it was good.

ConceptShare – This one looks really nice, but it’s not made for flowcharting so maybe I shouldn’t even include it in this list. I will say that they did a great job on the interface and I imagine that it serves its purpose (sharing designs) well. One thing I noticed, and the reason I’m including it is because I wanted to comment on this, was that the lowest priced for-pay plan is $19 a month… that’s $228 a year and you can’t even custom brand it at that price. At the $1188 a year plan you get that feature. I think I’ll stick to posting an image online and making a conference call to discuss it.

Imagination Cubed – This is a fun toy. There is no built in chat, no undo and just not enough features to make it feasible for our purposes despite the smooth interface.

Vyew – By far the most featured, you can share desktops, add maps, draw lines and shapes etc. but you can’t have a box with text in it… at least not without using one of the plugins which is frankly almost better than nothing at all in its current state. Vyew might have potential, but right now the tools are very awkward and it’s nowhere near as easy to use as OmniGraffle or Visio. TechCrunch called it ‘fantastic,’ I’d call it passable.

In the end what did we end up doing? Nothing really… we spent the time pondering the lameness of web based collaboration and we’ll probably just make it in some desktop application and email the file back and forth. I’d be happy to know if anyone else has found a better option.

[EDIT]
Ahh. I knew I’d given up too soon. Not to disappoint readers on a blog called “Best Tool for the Job,” I felt obligated to continue the search (thank me later :)). I just re-found Gliffy.com and it works like a charm. The collaboration part isn’t real-time–it looks like you have to click a revision in the list on the right to get updates and there is no built in chat, but otherwise it works really nice.

It has (almost) every feature we need and even some fun ones we don’t. Nice.

If you’re still using QuickTime, which does not support full screen video playback unless you buy QuickTime Pro, check out the follo

wing free video players. They are listed in the order that I prefer them:
1. NicePlayer – simple, fast, full screen (or borderless at any size) video playback. It can play DVD’s, playlists and most any video file you throw at it. This is my default video player. Mac only.

2. VLC – If you’ve got something that won’t play in Niceplayer, try VLC (Vido Lan Client). VLC can play almost anything you throw at it, including many streaming videos. Recently the interface has improved quite a bit as well. Cross-platform, open source.

3. MPlayer and/or djoPlayer – They’re based on the same open source video engine, but with different takes on the interface. I usually only drop to MPlayer as a last resort, but for a last resort, it works really well. MPlayer is cross-platform, djoPlayer is Mac only. If you’re on an Intel Mac stick with djoPlayer.

Since I started learning Rails I’ve often been asked “is Rails hard to learn?” A lot of times this is by people who don’t know any other programming language or even HTML. The answer to that question is a little more complicated than a simple yes or no. Rails isn’t necessarily hard to learn, but a lot of other stuff comes along with it. Here’s the list I came up with of the things you’ll have to learn to write web applications in Rails:

• The programming language Ruby
• Obviously Rails itself which involves learning the Model View Controller (MVC) design pattern (or collection of patterns) and the way these are implemented in Rails, the file structure of Rails and the syntax and domain specific functions Rails adds to Ruby including how to write templates using RHTML. Rails is composed of several frameworks, ActiveRecord, ActionPack (which includes Action Controller, Views, Mailer and Web Services), each of which have to be learned.
• How to use Rails plugins, components, Engines Ruby gems etc. This includes how to get them installed along with learning enough to know when (or if) and how to use them.
• AJAX, Prototype, JavaScript and RJS. You may not have to learn JavaScript (which itself is a full featured programming language) but you’ll definitely have to be comfortable with using it to some degree.
• What web services are and how they work.
• How to create and use relational databases.
• Basic SQL, at least enough to know what is happening behind the scenes with ActiveRecord. There almost certain to be times when some SQL will have to be written out for reports, optimization etc., so knowing at least some SQL is important.
• Having enough of a knowledge of FastCGI, Mongrel and WebBrick to make a decision about which (or which combination) to use to deploy the application.
• Apache, specifically how to configure it to work with either FastCGI or Mongrel. Alternatively Lighttpd or another web server.
• Rake, Generators and Capistrano and remote deployment.
• Database migrations.
• Testing web applications (which admittedly I haven’t done much yet).
• A basic knowledge of web application security.
• How to set up and use SVN repositories. If you’re new to source code versioning this can take awhile to get used to.
• It may be necessary to learn a new IDE (RadRails) and/or a new text editor (TextMate).
• As with any new programming language, you’ll have to learn to get Rails installed. In my case this meant figuring out how to do it on my personal computer (a Mac), my work machine (Windows XP) and the servers (Linux). None were too difficult but they all had their idiosyncrasies that had to be dealt with.
• If you don’t already know it, you’ll need to learn XHTML and CSS

Some of the things in that list are quick and easy to learn, others will take time and practice (I’m still working on a lot of them). If you’re thinking about learning Rails, this list isn’t meant to discourage you, just help to make you aware of what you’re up for.
