Free seems interesting and obviously useful, but maybe not right away? Here is what I was thinking:

• Course begins; $5 per class (Mostly for bandwith/server costs)
• All the lectures, reading etc is passive, and doesn’t cost the teachers anything
• For every question you ask the teacher/TA, a $0.50 charge goes to your account, which you pay off monthly
• Obviously, help obtained from community support (class forums, chat) is free

This seems like it could be sustainable, especially as some of these courses get larger.

What could be done is, at the end of the course, the content is freely-accessible. Still, questions can be asked anytime for that $0.50 charge.

Anyway, I’m interested in what the course offers:

Description: Web applications have the power to provide useful services to millions of people worldwide. In this class, you will learn how to build your own blog application starting from the basics of how the web works and how to set up a web application and process user input, to how to use databases, manage user accounts, interact with other web services, and make your application scale to support large numbers of users.

WEEK 1: How the Web Works

Introduction to HTTP and Web Applications

WEEK 2: How to Have Users

Getting and processing user input

WEEK 3: How to Manage State

Databases and persistent data

WEEK 4: Whom to Trust

User authentication and access control

WEEK 5: How to Connect

Web applications as services, using APIs

WEEK 6: How to Serve Millions

Scaling, caching, optimizations

WEEK 7: Changing the World

Building a successful web application, project

A lot of this I know, though I’m mostly self-taught. I try to find standards compliant places to learn from, but I always fear there is a better way out there to do certain things; this should help with that.

Week 6 looks the most interesting, as I don’t have experience with scaling. I have lots of things I implement to handle scaling, but haven’t gotten the traffic to really put them to the test.

I’ll keep posting about my experience.

Adding an entry to ICLS

That’s right, I actually finished a side project. I worked on this on my lunch breaks occasionally for 2-3 months. Behold!

ICLS (Inconceivably Complex Logging System)

On Github: https://github.com/timbotron/ICLS

Summary

ICLS is a command-line, python-based logging system that supports tagging, searches, reports, etc. It stores this data in Amazon’s SimpleDB, (in your account of course). Specifically, it’s designed for a contract worker to be logging what they are doing at that time, bugs they figured out, etc. However, there are many other potential uses, such as having all your servers sending their log messages to one location.

The Name

Why call it ‘Inconceivably Complex’? Because, in one sense, it’s rediculous. You need to write a log? Write to a flat file. Writing to a cloud-based NoSQL data system is completely overkill. OR IS IT; I THINK NOT.

Notable features include

• Dead-simple to add an entry (icls “entry text here”)
• Tons of options (Default tag, search by term, tag, date range, etc. see documentation)
• icls.conf config file
• entry retrieval and deletion

A report using a date range.

Requirements

• Python
• Account with Amazon Web Services
• Boto, a Python package, I didn’t want to use any packages, but using boto makes the auth, etc much easier. And at the end of day, I want to get this working, not take forever re-inventing the wheel on HMAC signature generation.

Reason for Building

ICLS is a side project. I wanted a log I can throw all my little random posts into, without feeling weird about compromising the ‘professionalism’ of my identi.ca/twitter account. Also, I wanted to try working with Amazon’s SimpleDB, and continue to strengthen my Python skills. And it totally worked for that, I feel more confident in my abilities.

Example of a search by tag

That world is here, now.

How can we arrive at this world, you may be asking? That answer is simple. StatusNet.

StatusNet is an Enterprise level, open source, web-based microblogging platform. Very similar to Twitter/Facebook (hashtags, direct messages, groups etc), but it can be hosted internally, and is customizable. (Increasing text limit, for example.) For those unfamiliar with the concept of microblogging, StatusNet has an excellent simple tour.

How this could work for your company

Imagine being able to follow specific hashtags. Some examples that come to mind are customers (#BobBoblaw, #Sony), products (#widget3, #turbowidget), or even technologies (#postgres, #linux).

Here’s an example:

Bob Hall on the second floor is having problems with a #postgres db, so he asks:

Having problems in #postgres getting it initialized so #turbowhidget can hit it. It’s at #CompanyX. Any ideas?

John Doe on the first floor follows the #postres hashtag, because he loves it so. Bob’s message pops up on his timeline, so he replies:

@bhall Have you checked your postgresql.conf that the listen addresses are correct? #postgres

Bob Hall has that reply pop up in his timeline, since he is mentioned (via @bhall). He didn’t know John was such a postgres whiz, and is happy he has the answer. But consider the secondary benefits.

• Anyone else who follows the #postgres tag will see these messages.
• Anyone who follows #CompanyX will also see this message (Think someone in Support on a ticket while Implementation is onsite)
• Anyone who searches postgres later will see this information
• Anyone who, later on, is having problems with the postgres installation at CompanyX could easily find this information

Email aliases go poof

With StatusNet, we wouldn’t need to create a new alias for every project and group that is created. A group could be made in StatusNet. How is that better than aliases, you might be pondering?

• Groups are in one place, you can search them
• Anyone can see a list of a groups members
• Members of a group can post a notice to that group. All other members of that group will see that notice in their timeline
• Anyone can send a message to a group, even if they aren’t a member via the bang. ‘!’ (ex. ‘Hey !IT the internal blog seems to be down‘)

Feeds for everything

StatusNet generates RSS feeds for every hashtag, user, and group. You don’t need to even necessarily keep StatusNet open, you can be pulling in a feed for those hashtags you want to follow, into the tools you already use. Integrate a hashtag you use into Insight.

Notifications

By default a user is notified via email when someone mentions or sends a message to that user. The user can also decide to configure their account so they receive notifications on their cell phone.

3rd Party Apps

There’s an app for that, seriously. PCs, (Windows, Mac, Linux), iPhone, Android, and the list goes on. If we allow external access to our StatusNet, a user can easily connect and update from anywhere, if they choose to.

Extras

Besides the functionality mentioned, there are other features we can activate. Be able to attach a file to your notice, post a bookmark, make a poll, etc.

Summary

I hope this encourages the reader to check out StatusNet if they haven’t already. The things it can do for a companies internal communication are amazing.

Github: http://github.com/timbotron/JPEF-Magic

What is JPEF Magic, you ask?

JPEF (Javascript, PHP, Email Form) Magic is a package which handles email forms in an elegant and simple manner. Essentially, it lets you add email forms to your site and deploy addition email forms down the road much quicker then creating each one from scratch.

Notable features..

• Consolidation; instead of validation and post-processing on each form page, handled with one file
• Email generated has full text from questions on form
• Settings for email processing (Email Subject, From, etc) are handled in hidden inputs on form
• After success, passes all the email body to the ‘on success’ page you’ve set up
• Allows you to have one “Form submitted successfully” page, with the users info displayed.

Why did I make it?

I come across this need all the time. I always think, “Oh I’ll just throw a form together.” but after you take care of the php to mail it, error checking, it does take time. Couple that with the fact I hate using the name value in emails as the question. I wanted a way to just have the exact language of the question on the form be what was included in the email, with minimal duplication by me. Hence, JPEF Magic was born.

It is getting colder, as Autumn is losing territory to it’s rival, Winter. That means soup should be the lunch of choice here for a while at the office. There’s only one problem.. I have no bowl.

I ended up ordering this:

It’s perfect! A handle so I can easily carry it back to my desk, but big enough to handle soup cans of all sizes, and homemade soup as well.

You can find it Here on Amazon

First thing that was tricky is, where is the “proper” place to install it? There is much debate on this point still, but I believe that installing to the /opt directory seems to make the most sense.

So we’ve downloaded the Firefox version we want to install:

[text]firefox-7.0.1.tar.bz2[/text]

It is sitting in a directory:

[text]/home/tim/downloads/[/text]

I open up a terminal and type:

[text]sudo tar -jxvf /home/tim/downloads/firefox-7.0.1.tar.bz2 -C /opt/[/text]

What is this command? Let’s break it down:

• sudo – “The following commands we are going to run as super user”, necessary for putting things in the opt directory.
• tar -jxvf – The tar program is what can compress and uncompress archives. We are using the options jxvf
  • j – the compression method that was used is bzip2
  • x – We are going to be extracting the archive.
  • v – We want the output to be verbose, so we’ll see every file extracted.
  • f – We are going to tell it the file to extract.
• /home/tim/downloads/firefox-7.0.1.tar.bz2 – The full path to the Firefox archive we are going to be installing.
• -C /opt/ – We want to specify the directory /opt/ as where it is going to be extracted to.

Then, bam Firefox should be extracted to the /opt/firefox directory. Then what do we need to do? Well, depending on your Linux distribution, you need to add a shortcut to that to your menu somewhere, so it’s easy to get to. The program the shortcut should point to is:

[text]/opt/firefox/firefox[/text]

UPGRADE: For upgrading your Firefox install you have in the /opt/ dir, you do the exact same thing.

Now I don’t have to spend the 1 min remembering how to do this every time a new version of Firefox comes out. Hope it helps others.
