Happy New Year everyone, hard to believe it’s already 2012. But here we go, another year is here!
So in a normal brain fart moment, I failed to remember several of my own teachings when adding a second Access Point to my home network. You see, I have ATT UVerse TV service at home, and for those who don’t remember it uses IGMP to multicast the TV feeds to the receivers. So if you for example, have a receiver plugged directly into the 2Wire modem, it will send the traffic out that port. Now, if you have that receiver plugged into a switch and share the drop with other devices it still comes down that line, however the switch more than likely does not understand multicast. Unless you have a more expensive device in there that is.
But here’s how this works. A packet that is a multicast packet, the first part of your MAC address will be a 01. If a switch understands multicast packets, then it will deliver that packet out the port of the device that is part of that multicast group. (IGMP Group). Now lets say you have a switch that doesn’t understand it, know what it does then? Yup, it treats a multicast packet as a broadcast packet and sends it out all ports but the one it came in on.
Now, lets say you have a brain fart moment and forget this and try to plug an access point off a line that has a receiver. Guess what happens to that access point… Well the short story is you will see it work… until you try to connect to it. There would be so much data trying to hit the wireless that your connection will time out.
So you have a couple fixes.
1. Reshuffle your network so that there is nothing on the same line as the receiver.
2. Run additional cables.
3. Replace your switches with ones that support IGMP/Multicast.
4. VLAN your network, and isolate the receivers. (Which would also imply either your switches all support this or you ran more drops.)
or if you are me…
You run new drops, replace your core switch with a more business minded switch that supports multicast, and you VLAN your network and isolate the receivers. Then you go further and trunk the line to your AP’s so you can send a VLAN to a specific wireless SID and make it a public hot spot.
Oh the wife will not like me today. 
Hello all, and long time no talk. I seem to remember I had this here website that I posted schtuff on many times. Today I think I will make a post on the Mac mini 2011 model. Why? Well put simply, because I purchase one!
So lets look at this device from a certain perspective, mine!
When I was considering the purchase of this machine, there were a couple factors that guided me to it:
- Xcode
- Lion
- Desire to develop for iOS devices
- Simplicity of the machine as an alternative platform, while keeping my Dell workhorse as my primary desktop.
Yes I am a Windows guy, and that pays my bills. However I have been working for the past year to two years, to try and learn iOS development. And after a long time of finagling my way around not having one, it became obvious that for me to make any headway in the field I would need a true Mac for that purpose.
So, considering my purpose was to develop for iOS devices, my needs were limited to the lower end machines. Specifically I had my eyes on the Mac mini and the MacBook Air. These models were on the lowest end of the price point, and would accomplish my needs. So then I set out to narrow that down further, did I really need another laptop? Was I going to be annoyed by the small screens on the laptop? Well finally the nail in those decisions came in the form of the 2011 models. The Mac mini having dropped $100 from the previous year made the decision for me.
Now lets keep in mind that I am not using this device for a home theatre PC, and I do not plan to. This is because I already own an Apple TV and with it linked to my vast 380GB iTunes library, it does exactly what I need in that arena.
So from a pure hardware perspective, the base Mac mini carries the following specs:
Processor
2.3GHz dual-core Intel Core i5 with 3MB on-chip shared L3 cache
Memory
2GB of 1333MHz DDR3 memory
Graphics
Intel HD Graphics 3000 processor with 288MB of DDR3 SDRAM shared with main memory
Storage
500GB (5400-rpm) hard drive
Ok so right out the gate I ordered 8GB of memory from NewEgg.com. And after receiving the unit, but not the memory… I had a good chance to feel the difference. Without the memory, the system is taxed, and at times quite sluggish when you have multiple applications open. Including when those apps are just Safari and Xcode. However, after I replaced the memory, it is like a different machine. I no longer have those sluggish moments.
The system has a single drive, and no DVD (SuperDrive). However for me that is not a problem. I don’t have anything I would use it for that would need that since I still have my other machines. Additionally, if for some reason I do need to use a DVD drive, I can use the “Remote DVD” feature where I share it off my desktop.
Additionally, I have not replaced the HD in it yet since 500GB is enough for me in the interim. And long term, it appears to have the room so I should be able to add a drive instead of replacing it assuming I can locate the hard drive wrap and cable.
Additionally, I don’t so far have a need to use OpenCL, since this particular model does not support it. However that doesn’t stop this unit from playing games. I have tested it with World of Warcraft on max settings, and Half-Life 2 Episode 2 on max settings, and it just hums along.
So how would I rate my experience with this device? Well I would give it a 9/10. The device performs above my expectations once the system has been upgraded to 8GB of memory. And my coding experience is very smooth and unabated by the device itself. Apple has done an amazing job with this little device, and I’m sure that if anyone else out there is looking for a coding machine to step into the field, this device is the perfect item!

I sure hope you are all out there testing IPv6 today! If you are not, shame on you for dragging your feet and holding up progress.
For those who want to, go sign up for gogonet and install their IPv6 tunnel client.
Sphere: Related ContentSo I’ve been quiet now for a bit, but here is the story on what I’ve been working on lately. Recently I’ve been helping do a migration from Exchange to Google Apps using ADFS 2.0 as the SSO. Everything in regards to authentication is working, but to simply user support and provide the end user the ability to change their own “built in google apps user” without envolving IT or purchasing some expensive product… I have created my own.
It will authenticate the user against ADFS and then using the Google API will allow that user to change their Google Apps User password to one they define. This allows them to set/reset their password that is used by non web requests such as IMAP, desktop software and mobile phones.
Here is a current screenshot, but no public code release yet.
UPDATE May 13th, 2011:
I have continued work on this project and now at version 0.6.0 it is almost to a completed first render model of the application. New features I have added:
- History Per User/Viewable by user.
- PIN Code Creation with detection of missing PIN and forced creation.
- Streamlined Menu, using DevExpress components.
- Various performance enhancements and bug fixes.
Coming up next:
- Implement PIN Code Management.
- Implement PIN CodeĀ usageĀ in password change routine.
- Implement PIN Code encryption routines.
- Implement password complexity logic.
- Implement PIN Code validation logic.
I’m edging closer and closer to completion and hopefully soon I will be able to move to Dual Password Change URL for Google Apps SSO. The goal of that project is to provide a Password Ā Change URL that you can use to allow the user to change both their AD password and the Google Apps user password at the same time.
Update June 3rd, 2011:
After another few weeks of being away, getting married and such, I’m back and have an update on the progress.
As above I had listed a few items coming up next, well here is what is now in this release:
- Implement PIN Code Management.
- Implement PIN CodeĀ usageĀ in password change routine.
- Implement PIN Code encryption routines.
- Implement password complexity logic.
- Implement PIN Code validation logic.
That’s right, that whole list is in now. The password complexity logic is based on complexity requirements from Google to try to prevent any account from being hit by the Captcha response system.
Up next on my plate of goodness:
- Implement Management Application For Site. This will be a standalone application that ties into the databaseĀ back-end.
- Implement theming on the site that is nicer than what currently is in use.
- Implement client side in page validation before delivery to server for validation.
- Implement fullĀ sign-outĀ and cleanup of ADFS cookies from management site.
In short, the iPad 2 has many great uses ranging from education to business uses. The one that I hadn’t even used yet was of course as a productive blogging tool. This post was created on my iPad 2, which I find myself using more and more each day over sitting down at my desktop or using my laptops.
Pretty amazing how a form factor like this can completely change your normal actions and uses of technology.

Meant to compete with the now infamous iPad, but in the same stroke vastly undercut the price. These devices can come so cheap you might just find them mixed in with gum at the checkout line in Walmart.
Please, don’t fall for the craplets! Show the world you want a real tablet!

Beginning today, new accounts will receive 10 cents off per gallon of gas until April 30th 2011. After April 30th the discount lowers to 2 cents per gallon off.
This card is a lot like the Speed Pass that Exxon has, which is just an account that links to your checking account for direct debits. It itself is not a credit card or a store card. But for 10 cents off a gallon, that beats the Walmart/Sams club discount and worth the use in my opinion.

Sphere: Related ContentThis Christmas was a great time of year, several things wound up under ye-ole tree. One of which was an Apple TV. Fantastic I though, and even further GREAT that I have a harmony so I won’t set the Apple remote on my bed head board only to watch it vanish into the nether reaches as it falls off.
Well that was until I started searching for Apple TV in the supported devices. There are several articles on how to setup Apple TV, but they all instruct you to mimic a Mac system and adjust remote timing, etc. However, with Harmony version 7.7.0+ it is much easier than that. And really, it only requires the understanding of where exactly Logitech decided the best place was to put the Apple TV. Also, considering the online device search from Logitech hardly if ever works right… the below is hopefully just to poke those who cannot find it into … well finding it!
So lets start off signed into the Harmony Remote Software, and guide yourself to adding a device.
You will want to add a device with the following settings:
Device: Media Center PC
Manufacturer: Apple
Model: Apple TV
After that of course I recommend changing the name of the device so that is says Apple TV instead of Media Center PC.
Click Settings on the device you added as your Apple TV, then under device options select āRename this deviceā and click next.
After renaming the device you can proceed with adding it into your activities. Which is the same simple method youāve always used.
A final note on the use of Harmony with Apple TV, you will need to ensure in the settings of the Apple TV for remotes, you are un-paired. Otherwise your new remote will not be able to control the device.
Now if only Logitech would add a āSearch for deviceā option in the Harmony software, the world would be perfect!

While toying around with the infamous “install mac retail on a pc” project. I had come across an item that is worth note. This item is when you are wanting to restore your old image created with Acronis True Image 2011. (With plus pack.)
Basically, if you want to restore an image of a partition that was created from an MBR disk to a disk formatted as GPT (Guid Partition Table) then you are unable to resize the partition up or down durring restore. This item came to my face a little to late, but none the less I consider it important enought o post on here. Maybe to save someone else who didn’t dig deep into the docs of Acronis.
If you need to restore a partition created on MBR to a GPT disk, be sure the partition you want to restore to already exists. As well as the size of that partition is sufficient to handle the restored image.
