Are you a cloud computing user? If you use PBwiki, you are.
Not only is PBwiki a Software-as-a-Service (SaaS) solution, but we also run significant portions of our infrastructure “in the cloud.”
If you’re interested in cloud computing, or in how PBwiki uses cloud computing to lower its costs and deliver better service, check out David’s panel at 10 AM on Wednesday, October 1.
While you’re there, you should probably check out the rest of the conference as well. Here’s how SDForum describes it:
The burgeoning availability of computing resources “in the cloud”, while still something that’s only being utilized by early adopters and for small projects, is going to transform software development as much as any of the revolutions mentioned above.
Join SDForum as we present our first-ever Cloud Computing conference. This daylong event will address the issues and controversies surrounding cloud computing help you to understand the technologies and risks involved, and enable you to figure out what, exactly, your company should do to take advantage of the ongoing revolution.

Wikis work best as a collaborative site where many people have access to read and contribute. Your job is to find people to contribute to the wiki — our job is to make it super simple for you to invite them.
Check out the many ways PBwiki 2.0 has made it easy to add folks to you wiki – including our new completely public wiki (coming soon!).
Individual invitations – Start small – add just one or two users. You can do this from the front page of your wiki, just enter their email address where is says “share this wiki”.
Add multiple users– If you have an excel or .csv file with users email addresses, you can bulk upload them using the “add multiple users” feature in the users section of the setting panel. This works wonders — just copy all the email addresses and paste them into the space provided.
Classroom Accounts– Your students don’t have email and you want to know exactly who is editing the wiki. Use Classroom Accounts to automatically create login accounts for your students and determine their permission level.
Request Access– You can send the link to your wiki and have your users click request access. Then approve them in the setting panel. This is good if you want specific folks to have access to your wiki, but don’t want to add them individually.
Coming Soon — Public editing – We are now testing a public editing feature for public wikis. This feature will allow anyone who has your wiki address to immediately gain access to your wiki — they only have to click “edit” and create a PBwiki account.
NOTE:This is not available for private wikis
Public editing is good for large collaborative wikis where you want everyone to have access and you don’t want the added step of approving everyone. Added benefit — you can create permission levels for these users and even remove them from the wiki.
What more could you ask for? In the comments tell us how you’re using your PBwiki and what features you would like to see.
When you think of taking a vacation cruise, you probably think of all the food you’ll eat, shuffle board you’ll play, and booze you’ll drink. But what do the folks running the ship think about? My bet is they think about some of the same things I think about everyday: keeping the ship operating smoothly, charting a halcyon course, and making sure that process never enters the minds of its customers. Come with me for a tour of the ship we pilot for the pleasure voyage we like to call pbworks.com.
“Safety first” isn’t just the mantra of cruise liners and middle school crossing guards, we take it seriously here, too. Your data is kept on three different PBwiki machines, then additionally encrypted and backed up off-site. How much data are we talking about? Your average desktop computer can hold about 200GB of data, of which about 6GB is your illegal music collection. We track over 25 times that amount: 5400GB of your data. In the past year we’ve had to triple the number of servers we use to store it all!
Engines are pretty important to cruise ships, but they’re also complicated and can break down. Putting in multiple engines is difficult and expensive, but it’s worth it: if one breaks down, you’ve got a spare. PBwiki is the same way with computers. Over the last year, we’ve worked to add “hot standby” servers that automatically take over if another computer experiences a failure. Ever wish you could just switch computers when Word or Windows crashes and pick up where you left off? With PBwiki you can!
Captains don’t drive a ship blindfolded, and neither do we. Earlier this year we fully instrumented our machines and services with a program called “ganglia.” It takes measurements and displays them on our dashboard so we can detect problems and calculate trends. The graph at left shows the effects of adding RAM to a beleaguered backup database: CPU usage drops and we are even more prepared in the unlikely event of a problem.
Although calling it a “captain’s log” would evoke too many Star Trek jokes, our Operations team logs all changes to the service, so we have a point of reference when tracking down performance issues, or to make sure certain checks were made. We keep it on PBwiki itself and simply call it the “log.”
Of course, this metaphor only goes so far: I haven’t yet secured the right to use deadly force to suppress piracy and mutiny. Apparently that would be against the “laws” and we haven’t relocated to my ideal office in international waters. Join me next time when we go into more technical details about PBwiki’s commitment to operational excellence!
