ubuntu 9.04

i really like the newest version of ubuntu 9.04 other people reporting problems with it but no problems here

The ball is roling - kinda...

So I'm busy with exams and don't really have the time to post anything technical yet. I do however felt that the two groups I started need to get some kind of momentum - so I posted one question I'm interested in on each group.

Check it out:

I hope to actually contribute something more technical from my side within the next week :-)

Difference between USB and IEEE 1394?

Let me start this off with the disclaimer that this was an apples to oranges comparison (or in this case an Apple to Dell comparison). The reason I thought this was interesting is that there was far more variation than I expected, on the MacBook anyway.

 The machines have similar processors (Intel Core Duo), with the MacBook having a slight edge, 2.0 GHz as opposed to the Dells 1.8 GHz.  However, the Dell has 3 GB of ram as opposed to the Macbooks 1 GB.

 Anyway, I have been trying to get the project I have been working on ( to run on my wife's MacBook with Mac OS X. I have done all of the development on GNU/Linux and it runs very well on all of the versions of GNU/Linux I have tried. I have been using these Western Digital 1 TB external hard drives for storage.  They have both USB and Firewire connections and I have used both on Linux and never noticed any difference (but I had never tested to see if there was any real difference).

A few nights ago I got it compiled and working on the MacBook, but when I tried to store files with the MacBook it was painfully slow.  It was so slow that it was unusable for what I was trying to do.  So this morning I decided to run a test to see if I could figure out what was happening.  I connected the WD drive with the USB cable to the MacBook, prep'd it and stored 111 photos (384 MB).  These are the times:

    real    17m3.569s
    user    2m17.587s
    sys     0m31.001s

Then I wondered if the problem was the USB connection so disconnected the drive and reconnected it with the Firewire cable and imported exactly the same 111 files.  It was 4X faster than it was with the USB connection:

    real    4m10.148s
    user    2m1.636s
    sys     0m28.276s

I thought this was pretty weird because I had never noticed that much difference between USB and Firewire when running on GNU/Linux.   So then I had to run the same test again to see.  I ran the USB test first, with the same 111 files:

    real    1m57.584s
    user    1m31.102s
    sys    0m6.368s

And with Firewire:

    real    1m58.318s
    user    1m32.070s
    sys    0m6.996s

I thought it was interesting that there was such a significant difference between Firewire and USB on the MacBook, but not on the Dell.  I have decided I will have to get a Mac and install Linux on it and then compare Apples to Apples, so to speak.




Hi everybody at Looking forward to get to know you.

New shinyness

Loving the new site.  I've been very curious about it since I heard the news that it was changing hands.  Content is currently thin for obvious reasons, but I really hope that it picks up and becomes a daily work distraction for me ;)

Kill the clients.

Heres a trivia for you all. Whats the single thing that creates most of the problems in an enterprise setting and what is it that demands such high level of conformity on the workstations? Why is it so hard in getting Linux into a organisation built on Windows technology?

 Its not security, management or  costs that makes corporations spend silly sums on certifying workstations and images. Its all about making various clients for databases work on the computers. Most clients are no more than very simple logic ontop of a database. Still very many of the client software demands a specific OS, a specific version and a specific level of patches. Add to that a good likelyhood that another client application demands another set of patches and your in for some really fun game of minefield.

 If more corporations would demand web applications (not .exe files disguised as web apps like .net or ActiveX) this problem would go away pretty fast. It would also solve the problem as old as the computers themselves, how do i access my stuff from outside the office, at home or  from abroad? A web application demands nothing more of the connecting computer than a browser if done right.

 The "problem" with Linux in most corporate enviroment isnt Linux itself at all. Its that it doesnt support the client applications.  The same goes for using any other OS for that matter.  Netbooks, smartphones and pretty much any gadget with a browser is out of the question without serious money poured into a ported client application to that perticular gadget. We are prisoners to our own networks more or less and cant really use all the various new exciting technology at all. The apps keeps us ten years back in time.

 Killing the client software is essential in freeing our networks and i strongly suspect Microsoft has long since realised this. The moment the database in the backend is decoupled from specialized client software and instead coupled to a webserver the race is more or less over except for games. 

 Nobody really wants policies, profiles, patchlevels, .msi packages and the living hell it creates but its just not possible making things work with the current model of connecting to our backends.

 What we in the open source community can do to better this is to not fall for the local client model and build all our services for the web. Things like Evolution, OpenOffice Base and Thunderbird should be  thrown in the dust bin and replaced with excellent web interfaces instead. Why would we want to create the same mess thats already rampant on the other side?


A bit of opinion

Well I just joined's community and I thought it would be nice to share a bit of opinion of the whole layout.


 I think they did great setting this up, it should bring the community closter together. I do like the general site, I just have to get use to it. 


So congratulations to the employees for creating a great networking site.

New here

So here i am on The new site seems to be great and it seems to me like it could get interesting here so i joined the community. I normally don't like social networking sites lets see if this is an exception.

However i think i will finally have to get rid of the sheep and make a photo of myself. I think it looks stupid to have this one everywhere. I think i will make one tomorrow, it's too late for a photo session now.


Introducing Myself to

First post.

 I'm new to the site, so I'll introduce myself.

 My name is Barry. I've been a Gnu/Linux user for about 6 years. I started because I was an engineering student fed up with waiting on the Sun servers to do my C programming homework. I'm usually friendly, but kinda emotionless and blunt at times. 

 I started with Debian Woody, shortly before Sarge released (2004). I wanted to get into GNU/Linux years before that, but never got around to it. I considered RedHat and Suse because they were packaged distros I could buy at the store with CDs and a manual and everything. But I also heard some people talk abotu Debian and how it was really stable and easy to maintain. When I finally took the plunge, one of the TAs for my programming class said he would help me if I chose Debian. That pretty much sold me and I installed Debian on my laptop. Since then, I tried a couple other distros, but none ever felt right like Debian did.  

Apart from computer stuff, I'm partial to craft beer and very expensive gin. If there's one thing that will bring geeks together that isn't computers, it's beer. I primarily enjoy oatmeal stouts, scotch ales, and IPAs, but I also go for wheat beer during the summer. Someday I'll try to brew my own.

One thing you should know about me: I got into GNU/Linux to learn about it. I refuse to use "easy" distros like Ubuntu because they hide the very things that I want. It's fine for others to use it, but I don't want to feel like I'm using Fisher-Price's My First Linux.  When people complain about how hard it is to do things in GNU/Linux, I laugh and tell them to be glad they're not using Slackware. When I get another spare box, I'll try Slackware myself. There are some things I can't learn unless I run an even less "friendly" distro than Debian, and my thirst for knowledge will compell me to move forward.

 That said, I also have a box running Debian kFreeBSD. It's not Linux, but rather GNU/kFreeBSD (GNU userspace on top of the FreeBSD kernel). This box gives me the most challenges, and is thus the most fun to use. Just getting sound to work was an adventure, and I felt like I was a better person for having overcome the challenge.

 So there. You can tell the kind of person I am by reading all that.  


Linux Mint Neueinstieg

Vor einigen Tagen bin ich nun von Ubuntu 9.04 auf die aktuelle Beta-Version von Linux Mint 7 umgestiegen und muss sagen, dass ich sehr begeistert bin. Eigentlich ist Linux Mint nichts anderes als Ubuntu mit ein paar Modifikationen, wie beispielsweise das Mint-Menü oder  die veränderte Software-Verwaltung namens mintinstall.
