I know a couple of people who are on the pess­im­ist­ic side of the Peak oil hypo­thes­is, and a couple who are equally fer­vent in their optim­ist­ic belief (the idea being that we’ll always find more and/or tech­no­logy will save the day). As is my wont, I’m some­where in the middle, think­ing we’re likely to find more oil and nat­ur­al gas, but that it should still be con­served, at least until we have more pro­gress on the vari­ous replace­ment tech­no­lo­gies. Someone (I for­get who) recom­men­ded I read James Howard Kunst­ler­’s book “The Long Emer­gency” (Amazon US link, Amazon CA link). It’s an inter­est­ing read, albeit a little dated (it was pub­lished in 2006). He tends to skim over some issues such as the import­ance of the trans­ition from lots of oil to little oil, and the writ­ing does tend to the breath­less (although it’s far bet­ter in the book than on his blog). I’d recom­mend at least skim­ming through it if you’re inter­ested in the issues, maybe bor­row it from the loc­al lib­rary as I did.

What the book did accom­plish was to make me think about the con­sequences of a world in which oil is much more expens­ive than it is now. It does­n’t need to be the case that we can­’t find any more; a ser­i­ous insur­rec­tion in Saudi Ara­bia that caused major dis­rup­tions to the flow of oil is not out of the ques­tion these days, and China is using an ever-increas­ing pro­por­tion of the world’s oil, which will auto­mat­ic­ally res­ult in price increases.

Some of the ques­tions are easy to ask: What hap­pens if the cost of ship­ping cheap goods from China trebles, or quin­tuples, or worse? What hap­pens to com­muters when the cost of get­ting to work is mul­ti­plied by 3, or 5, or 10? As the cost of heat­ing goes up, how many more people will die of the cold in unheated, unin­su­lated, houses? What hap­pens to the cost of food (a large factor of the Tunisi­an upris­ing) as the cost of the fuel rises, giv­en that the Green Revolu­tion that saved so many lives depends on cheap pet­ro­leum-based fertilisers?

The price of oil has­n’t gone below $50 per bar­rel for the last 5 years (accord­ing to http://www.oil-price.net/). We don’t know what’s next: it may hov­er around $100 per bar­rel for a while, or leap to a much high­er level; either way there should be at least some dis­cus­sion of what oil is best used for, what we can sub­sti­tute oth­er tech­no­lo­gies for, and an invest­ment in those tech­no­lo­gies before we need them. There are options already for power gen­er­a­tion, even if most of them also have issues, but there seems to be less focus on food and trans­port (both people and goods), and if any­thing, there seems to be an ever-increas­ing use of pet­ro­leum-based plastic mater­i­als. I don’t see much pro­duct­ive dis­cus­sion around these issues — any­one got good point­ers that don’t veer off too much into apo­ca­lyptic fervour?

The next stage in the great pro­ject to migrate back from Debi­an from OpenSol­ar­is: installing Debi­an. Wow, it’s so much easi­er these days! Here are my ran­dom notes from the install. I chose the net­work install option and burned the .iso to a CD. Then I booted from the CD on the boot­load­er (on a Sun Ultra 20, you hold down the F8 key while boot­ing to get to the load­er). Then it was just a mat­ter of pick­ing the options.

First option: graph­ic­al install­a­tion. It’s much easi­er to work on oth­er things and occa­sion­ally glance at the installing sys­tem when there’s a graph­ic­al user inter­face. I was­n’t sure what to use for the domain name, since this com­puter will be used inside the home net­work, so I left it blank for now. I can always change it later. I also picked the easy “one par­ti­tion” option as I saw no need for mul­tiple par­ti­tions. Then, I just let ‘er rip.

These days you get a nice list of pre­defined col­lec­tions to install; I chose the graph­ic­al desktop envir­on­ment (yes, it’s a serv­er that I’ll mostly access via ssh, but why not?), web serv­er, SQL data­base, ssh serv­er. Then it was time to wait and do oth­er things, like noti­cing how it’s rain­ing out­side. Again. April in Van­couver, sigh.

Some time later… Debi­an’s installed, and now I’ve decided to try The Debi­an Way to install Word­Press, rather than installing it by hand as I did last time I set up Word­Press on this box. apt-get update, fol­lowed by apt-get upgrade and apt-get install wordpress installs a bunch of stuff into /usr/share/wordpress, includ­ing a file, wp-config.php, which does­n’t appear in the stock Word­Press install­a­tion. Sure enough, it’s a Debi­an-spe­cif­ic file. Guess I’d bet­ter go and read some doc­u­ment­a­tion. I want to set up sep­ar­ate blogs with sep­ar­ate domain names, not just sep­ar­ate sub-domains, and Word­Press MU does­n’t do that by default. It will be inter­est­ing to see if the Debi­an ver­sion of Word­Press tackles that configuration.

Giv­en the cur­rent state of OpenSol­ar­is (pre­cari­ous, judging by vari­ous posts I’ve seen over the last few months) I decided to move the base­ment devel­op­ment and blog host­ing machine back to Debi­an. I mostly use it for a couple of small Word­Press blogs, and try­ing out vari­ous things (the odd Django pro­ject, Ruby on Rails, etc), so Debi­an is emin­ently suit­able for that.

Step one: move the Word­Press blogs on to an inter­im host­ing solu­tion, namely the same host where I cur­rently host this blog. My pack­age allows infin­ite add-on domains, so that works. To start with, I made sure I had no broken links on the blogs in their old home — I did­n’t want to try to hunt down errors in the new blogs that already exis­ted on the old ones.

The whole pro­cess worked fairly well (install new Word­Press sys­tem on new host, export the old blog, import to the new one) except for a couple of wrinkles, which I’m detail­ing here for next time I need to do this.

  1. when set­ting up the new blog, before you’ve switched the DNS, don’t put the final URL in the set­tings dia­log. This just means you can­’t log in to the tem­por­ary site and you have to go into PHPMy­Ad­min and fix the URL back to the tem­por­ary ver­sion. Get the site set up prop­erly first, then switch the blog URL and the DNS settings.
  2. The image attach­ment prob­ably won’t work. If you import the posts and check the “import file attach­ment” box, some of them will attach prop­erly, but not all, and you’ll have to manu­ally upload a cer­tain pro­por­tion of your images using SFTP or some­thing sim­il­ar. If you don’t check that box, none of the images will be attached to the right posts and you’ll have to manu­ally upload all of them. If you’ve used stand­ard markup to show pho­tos, that works any­way, but if you’ve used the gal­lery short­code, you’ll have to manu­ally attach the images to the post. The best plu­gin I’ve found to help with this is the Add From Serv­er plu­gin, where you can attach the images after you’ve uploaded them all. It’s still a lot of work if you have a lot of images.

Apart from that, step one went well. Now I have to make sure I have all the oth­er use­ful files saved some­where, and get on with the OS install.

Every year, when we start organ­ising North­ern Voice, the ques­tion comes up about key­notes. Key­notes set the tone of a con­fer­ence, they indic­ate some­thing of what the organ­ising com­mit­tee is think­ing, or what they think the com­munity that sup­ports the con­fer­ence might want to hear about. This year, I wanted to find someone as a key­note speak­er who could talk to us about the less sunny side of life, and remind us that some of the per­son­al stor­ies people share online aren’t about good things hap­pen­ing, they’re about life hap­pen­ing, and life isn’t always fair, or easy. The rest of the organ­ising com­mit­tee agreed, and we’re glad that April Smith agreed to present. “Storytelling From the Heart of the City” opens North­ern Voice on Fri­day May 13th. 

The Sat­urday key­note is a dif­fer­ent slant on the web, from Chris Wilson, who’s played a key role in build­ing many of the web tech­no­lo­gies we use every day. I’m not actu­ally sure what he’s going to talk about, but I have no doubt it will be an inter­est­ing view of the web world so many of us now inhab­it, sprinkled with inter­est­ing anec­dotes. I’m look­ing for­ward to it!

Two key­notes, two dif­fer­ent slants on what the web enables, two dif­fer­ent jour­neys. I’m not very good at chron­ic­ling my own jour­ney, but I admire those who do, and I hope (and expect) that the North­ern Voice key­notes will give strength and inspir­a­tion to all of us.
