Talk of a Microsoft Cloud#

Microsoft appears to be ready to offer a windows based service similar to Amazon's ec2.

I am not sure that I would make much use of this type of service, as I am looking for something more like GoGrid or Mosso (which I wrote about a few days ago).

Should prove to be very interesting...

The Cloud Comes To ASP.NET#

In the next 72 hours, you expect the new campaign to generate 10x more traffic than you have had in the last 72 days.  How do you scale to deal with this problem?

Do you buy more servers?

A few companies are starting to offer instant scalability for needs like this.  Amazon has been doing this for a while with their web services, but it isn't very useful for people who need the site to be running 24x7 (and it isn't very MS friendly).  But now there are other companies coming into play to provide the service I am talking about.

https://www.gogrid.com/

and

http://www.mosso.com/

Both offer the ability to instantly scale up your infrastructure as needed.  You can buy more CPU cycles, storage space, bandwidth etc, for a short time period.

This may (or may not) be ready for prime time, but it an interesting development for sure!

Couple of points on Network Load Balancing#

With Windows Servers, you can setup a cluster using built in Network Load Balancing.

The interesting thing about doing load balancing via software, is that once you get up around 4-5 servers, you stop gaining in performance when you add new machines, because of the added overhead associated with mainting N number of new relationships between the servers.

Also, if you use NLB and you set them up to not use any type of server affinity (i.e. a users request might hit any of the servers at any time) you will pay a serious penality if you are using SSL because each new request to a new server will require a new negoation of the SSL credentials.

What happened to my drive space (on my Lenovo laptop)?#

I was working on my father-in-laws laptop the other day and noticed that he was using up a lot of drive space.

I started poking around, but things were not adding up.  Of his 80 GB drive, about 30GB was unaccounted for.  I called a buddy of mine who was also running Vista to see if he had the same problem, and as it turned out, he was.

After some more investigation, it looks like this might not be a Vista issue, but is instead caused by IBM/Lenovo's Rescue and Recovery software.

I will have to confirm this later by actually fixing his computer, but I wanted to get this out there in case anyone else has a Lenovo laptop that is missing drive space.

Keywords:

Missing drive space, Missing disk space, Where is my drive space, Lenovo hard drive missing space.

Verizon EVDO Will Not Connect To Broadband Access#

On my new laptop, I had lenovo build it with a Sierra Wireless 1xEV-DO Network Adapter card built in to the laptop.

This means I should be able to access EVDO RevA "BroadbandAccess" basically across all of Chicagoland.  However, lately the VZ Manager software from Verizon has been only connecting me to the dialup-like "NationalAccess" and not the DSL like BroadbandAccess.  The signal shows that it is plenty strong, and I am using in the exact same places where I have used my old EVDO card, and even in places where my laptop worked at first.

This is so frustrating I can't explain it. 

I contacted Verizon, and of course they were no help.

So now I might end up in the situation of having to buy (and keep plugged in all the time) a pcmcia card for the verizon network, even though I already paid to have this functionality built into my laptop. 

This really stinks :(.

17xx-Controller in lock up State#

I had one of my clients call me today with this message showing up on their production server after the power went out (big storm in the area):

17xx-Controller in lock up State

The server is old, and so I started to think worst case scenarios:  the controller probably died, the data is probably lost, backups probably don't have everything, we are going to need a temp server, we are going to need a new production server etc.

Thankfully, this did not come to fruition, so if you get this error message on your Proliant, there may be some hope.

Go into the setup menu for the raid controller and you should be able to clear out the lock state simply by saving the settings.

Of course if your controller really did die, then this won't help you.

Renewing the SSL Certificate on a Network Load Balanced system#

We had a problem last night as we attempted to update our site certificate on our NLB website.

We have 2 machines in the cluster, and after updating the certificate on both of them, the site stopped responding over https.

We spent a LOT of time trying to figure out what was wrong with our new certificate, or the way we had set it up.

In the end, it turned out that that when we updated the certificate, it AUTOMATICALLY removed the NLB IP address from the IPs that are listening for port 443. 

So the result was that each server would respond over SSL on it's own, but when you tried to access the cluster by it's IP address over SSL, there would be no response.

It was really easy to fix, but a real pain to find.

Access to performance data was denied ...#

I have been getting this error in the event log of one of my clients servers:

Access to performance data was denied to UserName as attempted from C:\WINNT\System32\WinMgmt.exe

I first tried this:

Open the "Computer Management" app
Expand the "Services and Applications" section
Right-click the "WMI Control" entry & select "Properties"
Go to the "Security" tab
Expand the "Root" node and then select the "WMI" node
Click the "Security" button
Add the account & give it access

That didn't work, so I found another suggestion:

1. Run regedt32
2. Select the key SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib
3. From the menu select 'Security/Permissions'
4. Add the Internet Guest Account granting only 'read' permission

In case that doesn't work, here are some more articles on the subject

I should have bought APPL#
I really feel pretty stupid...

This weekend I read on a few tech blogs that Steve Jobs had invited his friends to attend his keynote address at MacWorld.

Obviously he was going to unveil something very cool, and obviously that "something" was probably going to be the long awaited iPhone.

It was at this point that I moved on to other things, instead of making the next "obvious" step.

Obviously this would cause Apple's stock to go up.

 



APPL was trading around 85 on Monday and 97 on Wednesday, an increase of 14%.

Maybe next time I will hear news like this and make the final connection :).

Resetting Domain Admin Passwords#

I have been researching ways to reset a domain admin password for a client who forgot what they typed in when they set the password.

Most password crackers work only on local accounts, not for anything on a domain.  It seems like the way to go about this is to reset the local admin account, then login using Directory Service Recovery Mode to reset the domain admin account.

Here are some of the articles I have been reading:

http://www.jms1.net/nt-unlock.shtml  <-- this idiot won't let you view his pages if you are running IE, so use firebox, but again, that's just stupid

My Sansa e200 Review#

I figure I should put up a review of my Sansa e200 incase anyone else is thinking of getting one.

I had a couple trips I had to take last month and my old Archos mp3 player decided to die on me.  Luckly for me I was able to find a Sankdisk Sansa e200 or e220 or e2XX whatever.  My model is the 6GB version, which is the largest they offer at the moment.

The unit cost $280 at Circuit City and while I could have got it online for $250 or so, I was going to be on a plane the next day so I didn't mind paying a little extra to have it with me on the trip.  Have I mentioned that I hate Circuit City?  Why is it that every time I got there I end up getting frustrated or pissed off?  I guess the one time I went there to see a TiVo demoed was ok... except now that I think about it they didn't know how to work the Tivo.  I ended up buying one and loving it though (this was back in '99).

Anyway, I have to say I am very pleased with the Sansa.  It was exactly what I hoped it would be in almost every way.

Battery life is awesome.  I think I read somewhere that it does 15 hours, which sounds about right.  I haven't had it run out on me yet.  Oh, this does bring me to one of the few things I don't like about it.  You can't listen to it while you have it connected to your computer, which means you can't listen to it while you are charging it thorough the USB.  Maybe you could "disconnect" through windows and have it still get power, but I don't know.

Playback quality and volume are good.

Navigation is IPod-like, which is ok, but rather than use a "touch wheel" they have an actual wheel you can turn that makes navigating easier in my opinion.  The only thing I don't like about navigation is that if you want to change to a song on another album by the same artist, you have to click Menu (down), Back To List (Middle), and then "Back" (Right).  I guess there is not obvious way to improve that, so overall I can't really complain.

FM Radio / Video: Well I will never be using the video, and I am sorry to say that as soon as I started using the FM radio I realized how much I would have rather had AM.  Oh well.

Audio Recorder: Haven't used it.

Graphics: I was a little suprised that there were now "Themes" to choose from, only the 1 default theme.  It's not bad, just something I would have figured they would do.  They show the album cover if you downloaded it, which is cool.

PC Integration: Awesome.  My winXP computer saw it right away as some kinda media device, no driver installs or anything.  You go to My Computer, click on the Sansa icon (it's almost like an external hard drive), and you just drag over your folders.  Once loaded, the Sansa will look at your MP3 tag info and index them all like the IPod does.

My wife bought me a little rubber case for it that I leave on all the time, and I have no worries about it breaking.  The thing feels really solid. 

Size: It looks bigger in these pictures than it is.  It's smaller than a large pack of gum.  Very nice.

Overall I am very happy with it!!  I would really recommend it to anyone who wants a great MP3 player, but doesn't want to get stuck with an IPod.

iDont.com#

Almost all of my friends have IPods, but I have held off. 

There are a number of reasons why:

1) ITunes:  It sucks.  I hate it.  My current MP3 player simply allows you to drag and drop the files you want onto your MP3 player.  No syncing, no problems.

2) User interface.  I know a lot of people think the wheel is really cool, but I think it overly involves the user.  Tell me what is wrong with up/down buttons before you redesign the interface to use a wheel.

3) Batteries.  As noted at http://www.ipodsdirtysecret.com/.  The battery in an IPod can not be removed, and some say they start to fail after 18 months.

Well I came across a site called http://www.idont.com/, which went live today (before today it had some anti-ipod message up there). 

Turns out it is a site for the new SanDisk MP3 player.

The e200 (really catchy name... not) looks pretty cool, and might be worth me looking into more: http://www.anythingbutipod.com/archives/2006/03/sandisk-sansa-e200-series-review.php

Moving a Network#

This weekend I helped a client of mine move their computer system to a new factility.  In the new location I racked up and configured an HP Procurve switch, and 2 Cisco APs.

All in all the move went well.  I had some problems getting into the Procurve at first.  I think the problem was a bad serial cable, but in the end I got it working right.

We didn't quite have enough ports on Procurve, so I uplinked a couple of their old switches until I could procure some more modules for the HP.

The Cisco 1100 APs had great range.  I was able to blanket the entire facility with WIFI access.  Pretty nice!

TiVo Hacks and other PVRs#
Slashdot had a review for a book on hacking TiVo, which led to a discussion of that topic and the various other PVRs out there.

I could walk to this guy's store from my parent's house. $85 to do the HDD upgrade, or you can buy the HDD yourself and just follow his directions. I'm not sure if it is worth $85. I could probably do it in an hour myself, but maybe just to make sure I don't screw it up.

Here and here you can find some forums on TiVo and hacking it.

Most interesting to me was the mention of MythTV, a linux based product that is free, and can support 2 tuners. Aside from that, it also can do a lot of other cool stuff from what I have read, such as pictures, audio, weather reports, web browser, web server, etc. I also read somewhere that you can setup one as a "

Interesting.

Hard Drive Sizes#
Finally someone is taking computer manufactures to task for advertising hard drive sizes in a false manner.

Hard drives store BINARY data. 1000 bytes != 1 KB, 1000 KB != 1MB, and 1000 MB != 1 GB.

So what does that mean?

1 GB is really 1,073,741,824 bytes. So the result is that a hard drive that is a "150GB" hard drive is really only going to store around 140GB of data. You just got screwed out of 10GB!

Here is the story.

Back Online#
Well.... it started with a buzzing CPU fan. I then tried to replace my entire motherboard, CPU, and memory. I got lots of STOP errors when trying to boot up after that as I realized that the newer mobo needed different IDE drivers.

I decided it wasn't worth it because I was going to be upgrading from a total POS to a not as crappy POS.

Some time in the future I'll just buy another dell server, move everything over, upgrade the mobo and use the computer as a test machine or backup server or something else... But I did migrate the server into the main floor of my house, so now its out of my room and hidden behind the entertainment center. The backup machine is going there next.
