Comming Soon: “PHP Web 2.0 Mashup Projects” Book Review

PHP Web 2.0 Mashup ProjectsI should be receiving a “PHP Web 2.0 Mashup Projects” from PACKT publishing in the mail sometime soon, once I get it I’ll try to have a review up in a couple of weeks.

If you are interested check out the full book description at PACKT publishing

I’m pretty excited about it, I was planning on starting a personal mashup project to link Craigslist garage sale postings with google maps, so this book is coming along at exactly the right time.

Usability and creativity

So I was taking my morning stroll through popUrls when I came across two articles. One about CrazyEgg, a really cool tool for gathering usability statistics, and the other this really random, unconventional, whimsical, unprofessional, unattractive, outdated, not entirely original, and really really effective website for some hippie named Miranda July. (FYI – I call anyone who puts effort into being creative a hippie, although if they are mall style crafty I just block them out of my mind)

Anyway Miranda July’s site is a mess, she did it with a camera, a fridge, & a stove. However, despite me being 100% UNinterested in her product I read ALL THE AD COPY. I haven’t even read all the add copy for sites I’ve made myself, it’s miserable marketing gobly-gook because that’s what clients expect from “professionals”.

I think this sort of grass-roots, direct from the source w/0 any middle men, advertising is what will cut through the ad clutter so well described in this Frontline episode.

 

The lesson here is that once again “Content is King” and the ROI on details is difficult to gauge and probably not a high as most people think.

However…. if we go back to the the majority of the the marketing messages I(we) need to communicate a camera and a kitchen full of appliances might not be a sufficient tool-set, and a client probably wouldn’t “get it” anyway.

Enter CrazyEgg I read a really good introduction at Read/Write Web. I haven’t tried it yet but I think I’m going to push for it on my current project.

I’m tired of writing

Jay Pipes MySQL bottlenecks lecture

So last Thursday the majority of the MoCo Web Development team and I attended the MySQL Meetup featuring Jay Pipes of MySQL. It was hosted at Metro State U. in Minneapolis, MN the facility was top notch (read: they had pie and coffee 😉

Jay Pipes is an excellent speaker whose enthusiasm about MySQL is contagious. If you get a chance to hear him speak or back him into a corner for 20 questions I highly suggest it.

The thing Jay Spoke about that was most relevent to what I’m doing now was Horizontal Partitioning [article] [manual] which is taking a table with a very large amount of rows and breaking that heap into a series of smaller groups that can be intelligently loaded into memory on a as needed basis.

The obvious way for to do this for my, and I’d assume many projects is by, year. This would speed things up because my project’s users are most likely to only need to access the current year’s information. If I only ask MySQL to load up a table containing the current year then that’s a much smaller bite to chew.

Horizontal Partitioning can also be done with a hash of one or more other columns, which makes it very flexible, and very useful for medium to huge projects.

On a related topic I also realized that I’ve been asked by my supervisor to investigate the benefits of Vertical Partitioning before either of us knew what to call it. Essentially it’s breaking up tables and adding one-to-one relationships between them. This allows frequently accessed sections of the original table to be accessed in isolation without having to load a bunch of unused fields to memory. I’m lead to believe that some db’s handle this pragmatically but MySQL does not.

Another key points were that the most cost effective way to mitigate a MySQL bottleneck is to add more RAM to the server. This is essentially throwing money at the problem, but less money that the equivalent labor costs associated with other solutions.

Lastly the common yet important advice of “use the smallest data container possible” because “a BigINT is twice the size of a INT but a INT is twice as fast”.

There were many many other gems from this lecture, but I forgot my notes at work and I’m tired of writing
