Sexy hardware

Is it just me or did anybody else smiled slightly at the cover of April 2006 issue of Linux Journal? I do agree with the picture though, a PowerBook 12" is a sexy piece of hardware, even running Linux. Technorati Tags: apple, linux


I bought an iPod Video to replace my aging 2G iPod (well, officially I stole the 2G from my wife after my 1G broke the firewire port...) and to be able to carry my photos of my kid with me: grandmothers love that part. Anyway, when I arrive at home in the evening, I like to listen to music and usually what I did was start iTunes and use the built-in TiBook speakers.

First steps

There is a lot of people working to get a decent free Windows emulator for Mac OS X Intel. Some just want VMWare to launch their player technology, others seek the Q and QEMU solutions. All of this will eventually work, I'm sure. In the meantime, you can follow the progress of a VMWare-based solution. Aparently someone took the time to make VMWare for linux run under Knoppix using a iMac Intel.

Wildfire 2.5.0

Jive Software announced Wildfire 2.5.0 just now. They are now 100% XMPP compliant. Congrats! They are the second server with source available to make that claim, after ejabberd last December. I was still running an old Jive Messenger 2.3.1 so I decided it was time to upgrade. Installing a Wildfire is so easy that I never upgrade. I just export the users from the old server, do a fresh install of the new server, tweak two or three settings, and import the users.

Campfire is now live

I was expecting this service to open soon, and my wish was granted. I was able to grab the address and I'll test it with a couple of friends. As usual you can expect the clean look and interface that 37Signals have accustom us to. Only the minimum features are there, but for now, it seems very responsive. Given the recent example of Zooomr regarding authentication (only the good parts, of course), I would like to see 37Signals start some kind of distributed authentication system, even its only on their sites.


Hugo sent me a couple of questions last week that I finally found the time to respond. Hugo is a very patient person, I'll tell you that.

Follow-up to Authenticate Anywhere

Yesterday, Joel commented on my authenticate anywhere post, talking about the security and privacy problems with the Google authentication in Zooomr. He is right, of course. Zooomr asks you for your login and password. Of you GMail account. And that's not good. This is of course, because GMail was never designed to be an authentication mechanism, and people are abusing it. You could do the same with almost any ISP that offers POP3, for example, using that service to check credentials.

Tip: show process sorted by RSS

Several times I needed a way to quickly see which process are using the most memory on a Linux system. After reading a bit of the man page and with a tip from the Apache performance article I was reading, I settled for this: ps ax -yl --sort:rss (BSD syntax) ps -eyl --sort:rss (standard syntax) There you go. Update: corrected the command, thanks to Daniel Fonseca. I messed up BSD syntax (which I prefer) with standard syntax.

Authenticate anyware

There is new Flickr-type site making the beta rounds, called Zooomr. I found it via Dystopics review. I normally could care less about a new photo-site, but there is one feature that I'm just crazy about: distributed authentication. See the screenshot from their login page (taken from the above review): You can use Level9, OpenID, LiveJournal, Google and Meetro. OpenID is the cool one, for me, because it also enables you to use your Typekey identity for logging in.


Campfire is coming along and the first screen-shoot and screen-cast seem great. They have been conducting load testing on their service this last few weeks, and it seems that yesterday they did the last one before launch. It seems another winner after Basecamp and Backpackit, very nice, and well deserved. Technorati Tags: 37signals, campfire
