Blonko! � passwords (Update)

This can't be true , no really can you imagine us using passwords such as dnet-X , taHdeR, llevoN, esuS , ecruoSneX as passwords. But a company that claims to be a security company uses Sudnilet!‘ ? I really hope that nobody is using eruc-C , erucsA or even nezibU (noisiVteN) as a password.

I suggest they l change their passwords to !Mocagleb

Update: I just got word thas some company really is using nemlod as password

danwalsh: Linux fragmentation - a view from the Security community

Dan Walsh points out in danwalsh: Linux fragmentation - a view from the Security community that we are heading for fragmentation in Linux Security , that's really not a good thing. I can't comment on the technical App Armor side yet but I think he really has some valid points here.. lots of people have been using SELinux and learning it for ages now, there indeed was the need for making SELinux easier to manage however we didn't need a totally ne environment.

Apart from that you might remember my comments on Security and Easy configuration regarding to firewalling. I think it also applies to MAC. If you make stuff to easy to configure you will get Mr Joe Random Newbie who thinks he correctly configured something but actually opened up a whole lot more than he actually wanted to. A security tool really shouldn't be something that can be used by novice users easily, maybe they should realise that the topic is too diffficult for them and get some help from people who actually understand what they are doing.

On the other hand there is the Learning normal behaviour vs Learning Anomalies strategy,
which one do you prefer ?

I`m interrested to see how other distributions will catch on with App Armor, how soon will we see packages for Ubuntu / Fedora / Mandriva etc.. time will tell wether , and usually the best package survives, I`ll keep looking at both sides :)

On a side note, has anyone got statistics on the chances that a proprietary project gone open grows a real community vs an open source project from day 1 ?

A zillion reasons to use LVM in a Virtual Machine environment

So this question pops up on irc on how to manage disks for Xen Virtual domains ..

When I answer LVM people always wonder why .. afterall they only have one disk I often ask the following questions : How many partitions can you create on 1 disk ?
When not using LVM can you resize your paritions when you need them ? Do you often run into the
"The kernel still uses the old table. The new table will be used at the next reboot." issue when trying to add partitions ?

With LVM you don't have these problems , and those are only 3 of the LVM advantages that have nothing to do with striping, mirroring or snapshotting
Actually you just create partitions (/var/ /usr/ swap / etc .. in LVM's ) no difference between physical or virtual machine :)

So the next question that popped up a couple of minutes later was , wouldn't that be more confusing and complex than managing just some partitions ?
Wouldn't the overview become more complex ?

Actually the overview will be VERY clear if you use the correct naming conviention :)
Say you don't use LVM .. after six months would you still recall if you used /dev/sda9 for / and /dev/sda10 for /usr and if you did that for vhost or vhost2 .. ?
However say you have a volume group "virtual_machines" and in that volume group you have a logical volume called vhost1.root vhost2.usr
which one would you prefer ?

Ari Jaaksi's Blog: Where is Henry now?

Ari Jaaksi asks in his Blog: Where is Henry now?

Henry isn't called Henri anymore , he is now called Larry Page, , Sergey Brin or Jimmy Wales (only to name a few) , those are the people that turned Open Source tools into a easy to use platform that EVERYBODY is using Every Day.

PS. Tim O'Reilly already told us that in his Fosdem 2004 Keynote.

Multiple Front-End Solutions for Email and Calendaring?

A nice comment in anotherwise boring/Multiple Front-End Solutions for Email and Calendaring?
/. thread. Dave Gilbert says :

Lets get some convergence here - please can we actually lock the
Zimbra, Open Exchange, Sunbird, Open Groupware, Kolab
(I must have missed some....)
guys in a cave without food for a while until they actually agree to work together?
For a concession I'll let caffeinated beverages in and a few computers with a copy
of all known calendaring specs.

(please toss in a couple of guys with MS programming experience so we can get Outlook
to talk to the servers).

Great idea, so what about some conference organises a "Calendaring" track. Or Maybe a devroom for next year Raph? Nils ? Anyone ?

Maybe we can even throw in some funding for the food fight afterwards :-)

Uploading 2.6.15-openmosixbeta to sf.net

So everybody can enjoy it and start testing it , some warnings and guidelines however.
Please note that this is a BETA release, we want you to test it and report as much bugs and issues with it as possible.
We have tested this kernel version to have working process migration included, and people have reported migration back to the original node to be working also.

However I didn't get the chance to actually test this rpm as my whole lab is shut down while my windows are being replaced, I plan on being up and running again by the end of the week.

Hmm.. the, the rpm modifies your grub.conf and places a non working intird , mkinitrd solves that problem for you :) You have been warned ..
