Dear Lazyweb,

So, I’ve been in Chicago for a week teaching a beginner and an intermediate course on using and administering Linux machines. This week, I’ll teach an intermediate and an advanced course on Linux, and the advanced course will cover profiling and debugging. The main tools I’m covering will be valgrind and oprofile, though I’ll be going over lots of other stuff, like iostat, vmstat, strace, what’s under /proc, and some more basic stuff like sending signals and the like.

So what makes me a bit nervous is, being that the advanced students are mostly CS-degree-holding system developers, they’ll probably be expecting me to know very low-level details of how things are implemented at  the system/kernel level. I’d love to know more about that myself, and actively try to increase my knowledge in that area! Alas, most of my experience with low-level …

Lots of blogs list a bunch of stuff that happened in the year just past, and I have done a year-in-review post before, but in looking back at posts on this blog and elsewhere, what strikes me most is not the big achievements that took place in technology in 2008, but rather the questions that remain unanswered. So much got started in 2008 — I’m really excited to see what happens with it all in 2009!

Cloud Computing

Technically, the various utility or ‘cloud’ computing initiatives started prior to 2008, but in my observation, they gained more traction in 2008 than at any other time. At the beginning of 2008, I was using Amazon’s S3, and testing to expand into more wide use of EC2 during my time as Technology Director for AddThis.com (pre-buyout). I was also investigating tons of other technologies that take different approaches to the higher-level problem these things all try to solve: owning, and housing (and …

I've been working on our Freiwild Shop website today making it compatible with Django 1.0.2 (final(ly)!). Basically, what I've done is try to run it and fix where it errors following the direction documented in the manual. I think that the next days I'll see how I can optimize the MySQL usage a bit.

The shop I've build has little models and doesn't use to much fancy tricks. Among the changes:

• Templates: extends should be on the first line
  
• Models: should not contain anything Admin-related. This is actually very nice, seperating models.py and admin.py.
  
• Model Fields: maxlength changed to max_length, oldforms/newforms options disappeared, small stuff like this.

One of the best ways to keep up with your field and network at the same time is to attend conferences. It’s one of the things I look forward to every year. After learning that O’Reilly has decided to commit blasphemy and *not* hold OSCON in Portland, Oregon the same week as the Oregon Brewers Festival, I was inspired to look around at what other conferences I might attend in 2009. Turns out, this is a huge pain in the ass, because I can’t find a single, central place that lists all of the conferences I’m likely to be interested in.

So… I created a public Google Calendar. It’s called “US Technical Conferences”. It needs more conferences, but I’ve listed the interesting ones I found. In order to keep the calendar from getting overwhelmingly crowded, I’ve decided that conferences on the list should:

• Deal with open source technology in some way. This is purposely broad.
• Be at least 3 days in …

I have, in the past, worked for startups of varying forms. I worked for a spinoff that ultimately failed but had the most awesome product I’ve ever seen (neural networks were involved, need I say more?), I helped a buddy very early on with his startup, which did great until angel investors crept in, destroyed his vision, and failed completely to understand the Long Tail vision my buddy was trying to achieve, and I worked for a web 2.0 startup which was pretty successful, and was subsequently purchased… by another startup!

Working in academia for 6 years also exposed me to people who are firing up businesses, or projects that accidentally become businesses, and some of those go nowhere, while others seem to be on the verge of NYSE listing now, while a year ago they were housed in the smallest office I’ve ever seen, using lawn furniture for their workstations.

Of course, I’ve also consulted for, and been interviewed by, a …

Hi all,

Are you aware of the fact that you can use NetBeans IDE for programming with Python? It's still early in the game, but it's true. We've already set up a quick tutorial for Python at http://wiki.netbeans.org/NetBeansPythonTutorial.

As mentioned, it's still early, but efforts are already underway to provide tutorials that feature the following:

• Python and Django
• Database Interaction (SQLAlchemy, mysqldb)
• GUI programming (wxPython, pyGTK)
• PyQT4

I'll let you know more as the story develops.

Cheers!

I’ve been using Google Reader since it was created. I really love the *idea* of Google Reader. I like that scrolling through the posts marks them as read. I like that you can toggle between list and expanded views of the posts. I like that you can search within a feed or across all feeds (though selecting multiple specific feeds would be great).

All of that said, I’d like to explore other avenues, because I don’t like that there’s, like, zero flexibility in how the Google Reader interface is configured. My problem starts with large fonts…

I use relatively large fonts. If you increase the font twice up from the default size in firefox on a mac (using the cmd-+ keystroke, twice), and you have more than just a couple of feeds, you wind up with this really horrible side pane with the bottom half of it requiring a scroll bar, and the text wraps, and it just looks terrible. What makes this really REALLY REALLY …

Taming MySQL is… challenging. Especially in very large, fast-growth, ‘always-on’ environments. It’s one of those things where you seemingly can never know all there is to know about it. That’s why I really like coming across posts like this one from FreshBooks that describes a very real problem that was affecting their users, how they dealt with it, why *that* failed, and what the final fix was. Post a link to your favorite MySQL Problem and Solution post in the comments (oh yeah, and “subscribe to comments” should be working now!)

I’m not someone who wakes up every day and looks at how my blog is ranked by all of the various services. I check out my WordPress stats, but that’s really about it. However, someone went and did some of the work for me, and they’ve decided that, of the blogs that they read or that were suggested to them, this blog ranks #20 in a listing of 25.

I’m really flattered, but wonder if it’s an indicator that this is a quality blog, or that they should aim higher in their blog reading ;-P  Either way, listing 25 bloggers in a flattering way is a fantastic marketing technique, because most of us are probably egomaniacal enough to say “Hey! Look!” and link back to the list on *your* blog, resulting in lots of traffic. Kudos, and thanks Mobile Maven!

Note that I’m talking about using these tools in some kind of professional way, and more specifically, I’m talking about using Excel as a database, and using VPS hosting to host “professional” web sites. By “professional”, I mean something other than your personal blog, picture gallery, or other relatively inconsequential site.

Excel is not a database

Here’s the thing: Excel isn’t a database. Most people who don’t work in IT don’t seem to understand this, and they’re deathly afraid to actually communicate with anyone in IT, so they take matters into their own hands, and create problems so big that IT is forced to get involved, because at some point this spreadsheet becomes “critical” to some business function. Then IT gets even more bitter toward the non-IT folk, validating some of the reasons the non-IT folk went that route in the first place, and virtually guaranteeing that they won’t come to the IT …
