Easy Webcam Setup with Ustream

A friend who fled New Orleans and Luling, Louisiana showed me his webcast on Ustream. Ustream allows Mac and Windows users to share their video on a Ustream page. Unlike broadcasting a live feed straight from your computer, Ustream can handle thousands of visits, as my friend’s page had before his house lost power when hurricane Gustav hit Louisiana this morning.

Another service like Ustream is Stickam. Both are free so I suppose their business model is to just be purchased by Google.

If you have a webcam and a nice view from your window, give Ustream a try. Or you can just use it to watch emergencies like this.

Best of luck to everyone in the storm.

USB Drive PC Tools

PC Repair System from Daily Cup of Tech

USB drives can hold a lot of tools needed for PC repair, recovery, and diagnostics. The folks at Daily Cup of Tech put together a PC Repair System that fits on a tiny 32MB flash drive.

What to do

All you have to do is download the files and extract them onto a flash drive. If you put all the files in the root directory of the drive, you will have the option to auto launch the application menu when you insert the USB drive. The menu will appear in the system tray (bottom right). Right click on the system tray application and you will see the menu shown here.

As you can see, there are lots of useful applications for computer help tasks. See the PC Repair System page for more info on the applications, or just run them to see what they do.

It works

I recently used the included Restoration software to recover deleted files from someone’s computer in Alexandria, Virginia.

With a PC Repair System USB drive, you have an easy to use and powerful set of tools.

My MobileMe Experience

Oh My, MobileMe

You’ve probably already heard of the disastrous launch of Apple’s MobileMe service. Apple has taken a lot of heat for this and heads have rolled over at Apple HQ for it. There are still some remaining issues to be fixed but for the most part Apple has gotten MobileMe working. I’m currently using a free MobileMe trial to evaluate it to see if it will meet my needs. The biggest of my needs is getting all of my emails from several accounts on my iPhone as quickly as possible.

Push Email

If you use a standard POP or IMAP email account, you are limited to a 15 minute check frequency in the iPhone Mail application. In addition to that limitation, if you set up multiple accounts, it will drain your battery all the quicker. My solution was to set up just one account on the phone and have all the email accounts I want to get mail from forwarded to that one. MobileMe is the perfect choice because it offers push email. Instead of that 15+ minute wait for new mail notification, push means you get near instant notification of a new message. In my experience, near instant means about 10 seconds or less.

When MobileMe launched, it was simply unreliable. Some of my messages would arrive instantly, others would never notify me without opening the Mail app. Besides a couple of bad days this month, things have worked far more reliably lately although I still manually check the mail if I haven’t gotten any notifications in a while. Once I had my MobileMe account set up on the iPhone, I still had to get all my email accounts forwarding to my username@me.com email address.

VersaForward to Forward Email

I use Email Forwarding by VersaForward Service to get all my mail to my me.com address. You can set up all of your email accounts to forward to the email address you check on your iPhone. This is a service with a fee paid monthly or every 6 months. To get a discount, use the promotional code TECHDC when signing up for a free trial. That will give you 50% off the first 3 months. Alternatively, you can run home desktop versions of VersaForward either with the entry-level VersaForward Personal or the more powerful VersaForward Professional.

Once you’ve got your email forwarding set up, you can get all of your email messages on your iPhone in a timely and reliable fashion.

Other MobileMe Features

MobileMe does cost $99/year although it offers more than just an email address. Push contacts and calendar updates help keep your iPhone, Desktop, and laptop all up to date with your latest changes. The MobileMe Gallery is a very elegant photo sharing system which creates a website with your photos to share with others as you want to.

Besides mail, my favorite MobileMe feature is iDisk. You can basically consider this a hard drive that you have access to on your computer but the data is stored on the internet. It is the simplicity of iDisk on your computer that makes this so useful. It appears like an external hard drive would. Drag files to it like normal. You can log in to me.com to access the files on the iDisk so it is a great place to keep important files that you might need remote access to. You have a total of 20GB of storage on MobileMe. You can allocate this between email and data storage. The iDisk can work with Macs and Windows as well.

Give Me a Chance

MobileMe got off to a slow start but now that it is finally working, you can see the advantages that it offers. For me, the push email is the #1 selling point. As long as it continues to work, I expect to become a paying customer. The free trial lasts 60 days so you can try it yourself to see how you like it.

VNC and DynDNS for Remote Desktop Support

Connecting Remotely with VNC

One of my favorite software tools to use at Tech DC is VNC. If I have a client in Maryland, D.C. or elsewhere in the world when I am in Virginia, I can use VNC to take control of their computer in order to remotely diagnose problems or provide user training.

VNC stands for Virtual Network Computing. It was originally developed by AT&T Labs in Cambridge, England. It is open source and free. There are many “flavors” of VNC that use the VNC protocol. My favorite for Windows is UltraVNC because it has the added feature of allowing file transfers between the two machines. VNC exists for Windows, Mac, and Linux.

VNC has two parts. There is the VNC Server which serves up the image. And there is the VNC Viewer which views and controls the server computer.

DynDNS.org

One limitation is that VNC requires a static IP. This is where DynDNS.org helps. Most home internet connections have a dynamic IP address, meaning that the IP address changes occasionally. DynDNS.org creates an address such as “yourname.dyndns.org” that is always mapped to your latest IP address, so it is as if you have a static home IP address.

UltraVNC’s Single Click

It takes extra time to setup, but Single Click is a great tool that can be built at UltraVNC. It is a small executable file that someone can click on in order for you to take over their computer. This makes it simple for the person you are connecting to. It also has the added benefit of not needing to configure their router to forward port 5900 to their computer. Single Click is only available for Windows computers.

All Free

VNC is free and DynDNS has a free service that is all you need. You can purchase other remote connection tools that are sometimes easier to set up such as GoToMyPC.  But if you can configure them, VNC and DynDNS should provide everything you need to connect to remote computers.

Truly Erasing Your Hard Drive

Deleting is not Erasing

Most people delete their important computer files before they throw away their computer or donate it to charity. The problem is that file deletion does not overwrite files. Deletion just removes the operating system’s link to that data. Until the files are overwritten, they can still be recovered. This could give someone your valuable bank and credit card information from your web browser cache. It could give someone enough information to commit identity fraud.

While you could physically destroy the hard drive, there are software tools that will securely erase the hard drive so that there is no chance of reconstructing the original data. Software tools are even accepted by the US Government for most deletions of sensitive data.

Darik’s Book and Nuke

My favorite tool is Darik’s Book and Nuke disk. This is a free tool that boots your computer into Linux and then overwrites your drive in multiple passes. Depending on the level of erasure you choose and the speed and size of your hard drive, the deletion can take minutes to a couple of days.

You need to follow instructions to create the CD or DVD yourself from the iso file you download. Then you need to make sure the computer will boot from the CD drive, which could include going into the starting setup (BIOS) to make sure that the CD is first in the boot order. Then just put in the CD and follow the easy instructions.

Once you have Darik’s Book and Nuke disk, you can truly erase your hard drive and keep your information secure.
