AWS EC2 EBS Partition Resize

I recently noticed I was getting low on space on one of my EBS volumes I mount on my EC2 server. After doing some research (aka Googling) it seemed like a simple procedure: umount, snapshot, create volume, resize, and mount. I even found a concise page that detailed resizing an EBS volume with sample commands. However when I got to the resize step I ran into an error along the lines of "The filesystem is already XXX blocks long. Nothing to do!". Turns out I didn't mount the complete EBS volume as a drive but instead partitioned it. The snapshot and create volume steps had increased the size of the EBS volume but not my partition. Without a graphical interface the prevailing recommendation to use gparted didn't help. Thankfully I stumbled upon another blog posting about resizing partitions using fdisk without losing data. While that post dealt with another virtual server service the same basic principles applied. After carefully deleting and recreating the partition on my EBS volume keeping the starting sector and file type the same resize2fs finally worked and I was off to the races. In retrospect the partition table hacking makes sense that it would work but isn't something I would have thought to try.

BarCamp Boston 5

Had a blast at BarCamp Boston 5. Learned about some new technologies and topics that I'd love to play with and learn more about. Some of my favorites Cooking for Geeks, OpenFrameworks, Wolfram Alpha, and Introduction to jQuery.

I threw some slides together and gave a talk about Agile Programming Methods since there looked to be a bunch of interest. Kind of hard to compress everything cool about agile into 25 minutes, but hopefully I got a couple of points across.

What I was more excited to talk about was my continued sleep tracking with Zeo. I'm not quite ready to release a version of the software (still in prototype phase) but I've got an updated set of slides and screenshots. Thanks to those that attended and gave great suggestions on data that I could pull in and plot against.

Programming Language Trends

One idea that "The Passionate Programmer" recommends that I've always been intrigued by is the idea of mapping hot technologies along an early, middle and late adoption trend and seeing where the technologies you work with fall. It is a subjective exercise but does help you think about what is out there. Turns out for programming languages (not frameworks or toolkits) TIOBE Software has for some time now been producing a Programming Community Index that ranks programming languages. They have a methodology that I'm inclined to call good enough for most cases.

NoSQL Live Boston

Yesterday I attended NoSQL Live Boston and participated on the NoSQL in the Cloud panel. During the day I captured some notes for myself which are after a brief recap of some of the points I tried to make during the panel discussion.

Q: What benefits and pitfalls have you found with your use of NoSQL in the cloud?

Based on having used Amazon's SimpleDB service over the past 18 months.

Benefits: pay as go is great for starting off, zero maintenance, zero setup, scaling by spreading data across multiple domains, SimpleSB manages data replication and high availability

Pitfalls: new mindset required to use eventually consistent model, increase impact of network latency, keeping SimpleDB's limitations in mind (size of domains, attribute count, etc.)

Q: How viable are these solutions and what is hampering there adoption?

Viability: SimpleDB has a 2 year track record and recently added consistent reads and conditional puts/deletes opening up new classes of application possibilities.
Adoption: Need body of knowledge, best practice patterns and use cases are still emerging

Ignite Boston

Tonight I attended Ignite Boston. This was the first "the attendees make the conference" conferences I'd been to. From a single stage, a wide variety of short (5 minute) technology focused talks were given (full speaker list from the above link). The majority of speakers had their talks geared towards the format. Taking place at a bar was good for the social aspects, but the resulting background chatter overwhelmed some speakers that were not as adapt at speaking into the microphone.

MAX Talk: Continuous Integration with Flex, FlexUnit, and Ant

I'm going to be speaking at the upcoming MAX about Continuous Integration with Flex, FlexUnit, and Ant. The talk description is:

Learn about tools and techniques needed to get continuous builds, integration, and testing running with a Flex project. I'll cover the fundamentals of build and test automation, the popular open-source Ant build tool, setting up and running FlexUnit tests from the command line, and integrating the entire process into an automated build system. I'll also demonstrate Antennae, a publicly available set of templates for building even very complex Flex applications using Ant.

If there are particular topics that you'd like to see covered let me know.

Antennae: Ant Templates for Flex

I'm pleased to announce the release of Antennae version 1.0000. This is the first release since Antennae was migrated from Joe Berkovitz's blog up to Google Code. You can access the project at http://code.google.com/p/antennae/. This release includes a bunch of tweaks and new functionality. For those that are not familiar with Antennae it covers:

  • Macro tasks for invoking mxmlc and compc
  • Ready made templates for application projects and library projects
  • A robust system for importing and exporting assets from one project to another
  • A solid way to compose projects inside container projects
  • Dependency checking on sources and libraries to avoid unneeded recompilation
  • Handling for HTML page token substitution and web app deployment
  • Automated unit test suite generation and command line integration with Flexunit

This release is primarily aimed at getting the tools out there for public consumption. Future releases will focus on additional documentation and other ways Ant can help automate your Flex builds. Please let us know what other improvements you would like to see.

Flashforward Boston Ant Talk

I'm going to be speaking at the upcoming Flashforward Boston about Automated Flex Building and Unit Testing. The description hasn't made it up onto the site yet but is roughly something like:

A talk focusing on tools and techniques needed to get continuous integration running with a Flex project -- that is, ensuring that at any given point in time, your application is buildable and free of errors. I'll cover how to automate the build process with Ant, setting up and running unit tests both interactively from the command line, and integrating the entire process into an automated build system. All tools used are open-source and publicly available.

If there are particular topics that you'd like to see covered let me know.

Comment Spam

Over the past couple of days my blog has been heavily hit with comment spam. In the last 10 hours I've gotten more than 100 spam message attempts posted to my blog. I moderate all comments so none of those messages saw the light of day but I still have to deal with them. I've never really tuned the comment spam features of MT and I still haven't. Instead I installed a CAPTCHA system. Previously I had required TypeKey in order to leave a comment but that felt a little to draconian. Not everyone has a TypeKey account or wants to create one. Email whitelists are another option but that still requires that I approve or junk email addresses when they are entered.

I'm all about not even having to look at the spam. While this may mean I automatically trash some important comment or email, I think most people are coming to realize that when 90% or more of all email is spam, people will take drastic measures and at some point a message will be lost. As such I'm now running the SCode plugin. The usability of CAPTCHAs is a concern but unless I go back to TypeKey only comments I don't have another good solution at this point. In fact the use of TypeKey on my system just means that your comment will automatically be posted but you still need to enter the security code in order to post.

Architectural Blueprint for Flex Applications (MVCS)

If you didn't catch Joe Berkovitz's talk at MAX 2006 about an architectural blueprint for Flex applications, it is now posted on Adobe's Flex Developer Center. Joe is the Chief Architect of Allurent, where I work. It is a great read and introduces the concept of Model, View, Controller, and Service (MVCS). Best of all it comes with a sample application that embodies all of the principles outlined in the article.

SpamAssassin

I finally got around to upgrading the version of SpamAssassin that I use. I was previously running 3.0.2 and am now running 3.1.4 I also spent a bunch of time installing a optional Perl modules to enable additional features of SpamAssassin. Boy am I glad that I did. Prior to upgrading I'd say at least 20 spams were getting through a day. In the last 24 hours I've only see one spam that didn't get flagged and it was as close as you can get to not being considered spam.

This makes me happy. I've never been that good with email to begin with but having to spend most of my email time filtering through my inbox only made matters worse. The few times that I've checked email since upgrading I've almost not known what to do. It's sad, but spam in my email has become so common I've almost forgot what it's like. This is a good problem to have to readjust to.

I do have to say that the documentation that I've come across so far for SpamAssassin has been pretty disorganized. I find this really odd since it seems to be under the Apache Software Foundation, which having used many of their other projects, I've usually been happy with the documentation. I suspect that the SpamAssassin wiki holds the knowledge I'm seeking but damned if I can find it. In any case, less spam is good and AFAIK no false-positives.

Flag Day

Urgent Action: Free Speech at Risk!

As Secretary Powell wrote in 1999, “The First Amendment exists to insure that freedom of speech and expression applies not just to that with which we agree or disagree, but also that which we find outrageous. I would not amend that great shield of democracy to hammer a few miscreants. The flag will be flying proudly long after they have slunk away.”

Tell your senators that the flag amendment would betray the very principles the flag represents.

DVR and a Mac

Lately I've been playing with what can be done with my DVR and my Mac. It turns out the firewire port on the back of my Motorola DCT6412 III can be easily used to pipe video to the Mac. There is a great step-by-step manual at macteens. The only problem is that I can't seem to find a way to capture a program that I've already recorded. I start the playback and see the traffic on the Mac but nothing gets recorded. I suspect that some special flag is being set that prevents recording the program. Which is a bummer since I wanted to extract a news segment that a friend asked me to record. If you have any ideas, let me know.

Flex Beta 3

For anyone following Flex, beta 3 is now available.
From my experience, Flex Builder is much improved but there are still many quirks with it. There were quite a few Actionscript 3 language changes, but the documentation on them is good. My biggest complaint so far is that many MXML files in a Flex library project are not being handled properly by the MXML Editor which results in a complete lack of code assist. The same MXML file in a Flex Application works fine. I've not completely figured out why some of the files are so broken, especially when they seem to work fine on another user's system.

OpenID

I've been playing around with OpenID a bit tonight. It started off as a rant about a lack of standards from LiveJournal for a way to access protected or friends-only posts as someone who doesn't actually want a LiveJournal account. It was at that point that I stumbled upon some new features that LJ is adding for OpenID only accounts. Once logged in with an OpenID account you can read protected friend posts and the like. I'll have to see what can be done with the RSS reader that I use.

I'm trying out a tagging plug-in for MT. I've not decided how good it is, but I figured I'd give it a try. It's called Tags.App. They have a nominal donation request, which is why I'm interested in trying it before spending any money. My first issue, like I've complained about in the past, is that the documentation for the product is pretty bad. I'm not an MT hacker by any means and the minimal documentation left me out in the cold. I'll have to see if I can figure out enough to make it work.

Maine is old

I was reading an article in the NYT recently about the changes taking place in Vermont. The focus was on how few high school graduates were going to college in the state or returning after attending college out of state. As an aside the article talked about the median age rapidly increasing the state over the past few years. That got me interested in what that really meant. Thankfully the US Census has some statistics available. What I found most surprising is that Maine has the highest median age at 40.7. Normally when I think of old states Florida comes to mind. Vermont is ranked second for highest median age. What that means long term for either state I'm not sure, but I find it interesting in any case.

I think it would be great if they also included an option to read bar codes from digital pictures. For users that don't want to spend the money on an iSight or bar code scanner, but would rather not type in bar codes by hand, snapping digital pictures would be a great alternative. I'm guessing, but I'm sure most of the image processing logic being used by the iSight to read the bar codes could be adapted for reading digital pictures.
