Houston Techfest 2011 – Wrap Up

Had a great time this past weekend at Houston Techfest. Attended a couple of great sessions and also presented a couple of sessions of my own.  If you attended either of these sessions, please click the SpeakerRate links and rate the sessions and leave comments on anything you felt was missing so that I might be able to better present at future events.

Below are my thoughts on the two sessions I presented.

Deploying Rails Applications: Lessons Learned

This session was the weaker of the two.  Reason being is I didn’t prepare enough for it.  While the content was decent, it could have had a little more meat and a lot less fluff.  This is something I plan to correct in all future sessions.  However, the discussion, questions, and general feel of the room wasn’t bad.  I just think that I could have done a better job of delivering some real content on this session.

Cross Platform Development with Mono and C#

This session was better attended than I had planned. In the past talks I’ve given on Mono and cross platform .NET development were sparsely (if at all) attended.  I think a large reason for this is Xamarin, specifically their MonoTouch and Mono for Android products, and the interest they have generated in the .NET community for doing mobile development.  This session had good questions, discussion, and I even managed to get a little “wow factor” in with the csharp shell from Mono.

Final Thoughts

Overall the experience was good. I think that I can do better next time, but given the size of the event and how well the sessions seemed to go in general, I think that I did okay.  Again, if you attended either of these sessions, please click the SpeakerRate links and rate the sessions

Why Amazon’s Tablet Makes Sense for Amazon

In case you missed it, Techcrunch has announced that they’ve played with Amazon’s soon to be released seven inch Kindle tablet.  Since then there’s been a lot of talk about if this tablet will really be able to compete with the iPad.  And that’s where people start missing the point.

Amazon isn’t looking to make a tablet that competes with the iPad. They’re looking to compete with something closer to Barnes and Noble’s Nook Color.  They’re also looking for something that will heavily tie into their existing content outlets like the Mp3 Store, or the Instant Video service.  A content consumption device that plugs into Amazon’s store makes perfect sense for Amazon.  And by making it a seven inch tablet that’s (rumored) to cost $250, they’re looking for heavy adoption from those that already own a Kindle or are looking to get a Kindle.

That’s why this kind of tablet makes sense for Amazon.  They want something smaller than the iPad’s 10 inch display because they want the device to be light, and easy to hold in bed or on an airplane.  They want you to throw it in your bag without worrying about space.  And they want to be the one’s that sell you the content that goes on that device. And just like Apple, Amazon wants you to buy content through them Apple does the same thing with iPad and iTunes (and the App Store and the iBook Store).

The price point is worth mentioning, at $250 it’s half of the cheapest new iPad.  At $250 it’s also around $60 more than the most expensive e-ink Kindle.  If they can bring the price down to around $199 while bring the e-ink Kindle price down as well, then they have an interesting marketing position on their hands.  But still at $250, people are going to be interested, and they’re going to reconsider that $500 iPad.  The question among non-geeks is “Do I get an iPad or a Kindle?” (and the answer to this largely depends on what you want to do).  At the rumored price point, Amazon is hoping to help make such a question easier for the general public.

Have an idea? Ship It! – A Houston Code Camp Presentation

Yesterday, I attended and presented at Houston Code Camp.  You can see what others were saying by looking at the twitter hashtag #houcodecamp.  The event was a resounding success and I’m hoping we do another next year.

Regarding my presentation.  I presented on shipping an idea.  Taking an idea you have from idea/inception all the way to launching it.  I would say that my session went well, had a decent attendance, and good questions were asked during the session.  I have posted the slides for the presentation on SlideShare, and have a Speaker Rate page.  Please feel free to visit the links.  If you attended my session, please rate me over on the Speaker Rate link.

XKCD & Password Security

If you were on the internet last week, you probably saw an article, twitter, or Facebook post about the xkcd comic on password strength. The comic, which was (most likely) inspired by an article entitled, “The Usability of Passwords” basically says that using a multi-word password (3 or more words), is more secure than what I have referred to as “complex passwords” in past articles on this blog. The writer of the original article makes the point (which is what the xkcd comic points to) that passwords using three or more dictionary words, has more entropy and is thus harder to crack, therefore making them more secure. While there is a bit of truth to the article, it leads to some false understandings of how hackers actually go about hacking passwords, and make assumptions that aren’t entirely accurate.

Cutting Worker Costs on Heroku

When we launched Just for Bands, my partner Erick and I decided to go with Heroku’s cloud hosting service to host our LiveShow application.  The reasons for this had to do with simplicity in managing the “server” and cost.  Heroku is fairly cheap, and the level of service they provide through their add-ons only increases that value.  If you have a Ruby on Rails application to launch and you don’t want to think about servers, Heroku is definitely worth looking at.

Heroku Worker Dynos

When we launched LiveShow, we utilized what Heroku calls a “Worker Dyno” to handle background tasks, specifically sending emails.  Using a Heroku worker dyno allows you to offload work to a background task so that it doesn’t hold up the actual web server portion of your app.  The downside to worker dynos is they cost money, $0.05/hour to be exact.  And when you run one all day, everyday for a month, that can add up.  In the case of LiveShow, to the tune of over $50 a month. And for a company that isn’t making any real money at the moment, that’s a lot of money going out with next to none coming in. Continue reading
