My new laptop:

ASUS UL50 Series UL50VT-RBBBK05 NoteBook Intel Core 2 Duo SU7300(1.30GHz) 15.6″ 4GB Memory DDR3 1066 500GB HDD 5400rpm DVD Super Multi NVIDIA GeForce G210M

Cosmetics:

This is a very pretty laptop. The screen is crisp, the case is sleek, and the construction is solid. Not a lot of “bling” that distract the eyes. I cannot thing of a single negative to this ultra thin full size HD Laptop.

Performance:

Sure, you might point out that the Intel Core 2 Duo SU7300(7300) w/ 800Mhz FSB CPU only runs at 1.3Ghz, but for day to day use the system rarely jumps from 800Mhz to 1.3Ghz anyways. The 4GB DDR3 1066 RAM certainly helps out. I am not a hard core gamer, at least on my notebook, so the dedicate NVIDIA GeForce G210M Graphics with 512MB GDDR3 VRAM certainly help out. The system comes with Window 7 Home Premium 64-bit, but I dual boot it to my OS of choice, Ubuntu 10.04 LTS. The Hard drive is 500GB, so I left 200 GB for Windows and installed Linux on the remaining 300GB. With the 3D accelerated graphics, Linux runs like a dream.

Power:

The default battery seems to last a LONG time. Well over 4 hours with casual use.

Problems:

Ok, I will admit I don’t like Windows at all, but it seems to run fine on this machine. Why Linux still is not available from the factory is beyond me. Certainly it is a far more efficient OS choice for this device. That being said, here are the negatives:

First, the webcam displays upside down in Linux.  There is a patch to fix this, however. Second, there is a “glitch” that when you install the Nvidia drivers for Linux, you have to set “SATA” from Advanced to Standard in the system BIOS. Why? I don’t know, but if you don’t, the system hangs when it tries to switch from the on board Intel graphics to the Dedicated Nvidia card. That is the only negatives I’ve found. I don’t count the CPU Speed, because it’s not sup-par, it delivers exactly the level of performance it is supposed to.

Conslusions:

I love it! I picked it up on Newegg for $499.00 as an “Open Box” special. Newegg lists it at $699 normally. I will amend this post if I find anything noteworthy as I use the machine.

First, let me say that Google has been, in many ways, the biggest success story for the cause of Linux and Open Source, surpassing even the venerated Mark Shuttleworth and Ubuntu.

Today, however, I found a real problem. I will be careful to not point fingers, but I am somewhat suspicious.

After much resistance, I ventured into Cloud Computing with Google Docs. What to do first? I took my business’s general ledger (which I maintain in OOo 3.0 .ods) and tried to upload it to Google Docs. Fail. Unknown Server Error. That seems odd. It lists .ods as a valid import type. Ok, the file is around 30 sheets deep, so I’ll make it a single sheet. Same error. Well, just to see what happens, let me save it as a .xls. Uploads fine. What???

After some digging around on the interwebs, it seems that this is a common problem. There are various explanations about OOo, ODF, and the like, but the consensus is: It won’t upload .odf formats.

Why? I want so very much to say that there are some technical issues that Google is diligently working on to resolve the issue, but my inner fears keep screaming. Could it be that Google is trying to squash the only real threat to Google Docs (and MS-Office), OpenOffice.org? OOo is a WONDERFUL product, and I use it exclusively.

I want to give Google the benefit of the doubt on this. ODF has changed standards, and it could just be a technical thing. Either way, they need to figure it out, because they are making it look like the problem is with OOo. (Which is suspiciously close to Netscape “crashing” on windows oh so many years ago).

If you have any clarifying information, please email me.

So, you’re here, and you read something interesting or have a question, but you can’t comment because my site doesn’t allow comments. Why? Well, I agree that Blog’s are best as 2 way communication, but the simple fact is that I got tired of chasing down and blocking the ENDLESS parade of spam bots that submit bogus posts to my site. I get thousands of hits a day, and it takes me a long time to figure out which are real and which are bogus (The ration of real to bogus is 1:1000).

Got a question? You can shoot me an email at osprey at tranquilpenguin dot com and I would be happy to reply here or via email.

Well, I’ve finished my move and now that the smoke has settled, here’s where I ended up:

My webhosting business is now all on a co-located server in Seattle, WA. I am selling VPS’s to my business customers and all is well. See the good people at http://inmotionhosting.com if you need large scale hosting. See http://blmservices.com if you need end user web hosting.

My blog domain is still running on my dynamic DNS IP via my local cable internet provider.

My main workstation is running on an Athlon II x3 CPU on Ubuntu 10.04 LTS. The Dual Monitors are working great.

I’ve upgraded my Netbook and my Qosmio 17″ Worstation Laptop to Ubuntu 10.04 LTS as well. I’ve installed Ubuntu 8.04 LTS on my older IBM Notebook.

What does the future hold?

Well, that’s a good question. I’m doing quite a bit of web design work lately, but with the economy as it is, work is spotty. Folks are looking for good deals now so by cutting my prices I’ve been able to pick up a few new customers.

I may try out and review a few new distro’s in the near future. I am wanting to run the latest version of WINE though the paces and see what I can and cannot get to work.

Stay tuned.

I hate moving. Especially when it’s an unplanned move. Even more so when it’s on short notice, and you are a freelance network consultant running multiple web server out of your home. To make matters worse, I crashed a hard drive along the way, and won’t have a business internet connection for some time. Fortunately, I use no-ip.com so I am able to temporarily host this site on my dynamic IP. Hopefully life will return to normal soon.

Encrypted USB drive in Ubuntu

Today I went to the Linuxforum BOF day where I attended a session about encrypting your personal files. This made me remember a post read some time ago (check out the screen cast). I guessed that this functionality would be in Ubuntu Edgy by now so I just went ahead and tried to make my USB pen drive encrypted.

This is how I did it:

1. First install the needed software

   sudo apt-get install cryptsetup
   

2. Make sure your USB disk isn’t mounted. Then partition the USB pendrive the way you want it, if it isn’t already partitioned (I made one big partition on mine /dev/sda1).
   Note: Don’t mount the disk afterwards!
3. If you havn’t rebooted your computer since you installed the cryptsetup package, you might have to load the device mapper crypt module manually:

   sudo modprobe dm-crypt
   

4. Now make the partition encrypted:

   $ sudo cryptsetup --verbose --verify-passphrase luksFormat /dev/sda1
   
   WARNING!
   ========
   This will overwrite data on /dev/sda1 irrevocably.
   
   Are you sure? (Type uppercase yes): YES
   Enter LUKS passphrase:
   Verify passphrase:
   Command successful.
   

   If you get the error:

   Failed to setup dm-crypt key mapping.
   Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/sda1 contains at least 133 sectors.
   

   Make sure that the disk isn’t mounted. And make sure you are using the right device. You can use dmesg to check which device the disk have been assigned. You might also wanna check that the the module dm-crypt is loaded (lsmod | grep dm).

5. Now attach the encrypted partition.:

   $ sudo cryptsetup luksOpen /dev/sda1 sda1
   Enter LUKS passphrase:
   key slot 0 unlocked
   Command successful.
   

6. Now create a filesystem on the new encryptet device:

   sudo mkfs.ext3 /dev/mapper/sda1
   

7. Remove the tempoary device mapped to the encrypted partition:

   sudo cryptsetup luksClose sda1
   

8. Now remove the your usbdisk from the USB plug, and reinsert it and Ubuntu should find it and ask for the passphrase.

In this Article, Microsoft suggests placing taxes on Internet usage to fix security breaches…

Unbelievable. Microsoft produces Windows, which has been security ridden since it first entered the Internet. Microsoft has been pay VERY well for their product. Microsoft has not fixed their problems. Now Microsoft want the consumer to play extra taxes to help fix their problem.

I have another idea:

How about we dump the Microsoft garbage and just use Linux/Unix/BSD based Operating systems, and eliminate 90% of those security threats in a single stroke.
