11a-Noon
Q Russ in Greensboro NC - Film lenses on Digital SLR
They should work but unless you have the higher end CPU lenses they may not support all the features of the digital body. And don’t forget that you have to multiply the focal length by 1.6x since the digital pickup is smaller than the 35mm film. So a 50mm lens is effectively 75mm on a digital body.
Q Craig in Palm Springs - protecting a new laptop
Get a good anti-virus. I recommend Eset’s NOD32, no longer a sponsor of this show but still my favorite anti-virus. You should also download the free Microsoft Defender anti-spyware. (Read my articles in the Tips section on protecting your PC from viruses and spyware for more information.)
If you turn on WPA encryption on your home wireless access point you’ll be secure at home, but on the road I recommend setting up a VPN. If your office doesn’t provide one you can subscribe to www.HotspotVPN.com for $8.88/month. I use them and they work very well.
Another VPN is IPIG, a free service available from IOPUS.
Q Ivan in West Covina - remote backup
He’s looking for a business backup solution where they do it for you. Any suggestions? (See the comments for some suggestions.)
Q Chris in Baton Rouge - smoking computer
Sounds like the power supply burned up. Fortunately it’s an easy fix. don’t open the power supply — just remove it and replace it with a new one from PC Power & Cooling.
Q Nuru in Mission Viejo - setting up a home network
She’s got an unusual situation. Two computers access the office’s VPN so they’re safe, but she wants to use the iPhantom security device to protect a third that doesn’t use the VPN. Problem is, the iPhantom is not recommended for use with a VPN. To set this up she needs to set it up like so:

Make sure that your router supports VPN passthrough and it’s enabled.
She bought a second router to put between the iPhantom and the home computer, but that’s not necessary for now. She’ll only need that if she wants to put multiple systems behind the iPhantom. The iPhantom acts as a firewall.

Q Nick from Victorville - Xbox360 or PS/3
How good are you with delayed gratification? Sony is expected to announce a delay on the 15th. It may be some time before we see a PS/3 and it’s probably going to be at least $800. I’d go for the Xbox 360 now.

Q Christine in Ventura - more than one person logged in
But here’s what’s weird: she’s the only computer user in her house. When she starts up her computer it immediately complains that there are other people logged in. Unless I’m misunderstanding the situation, it sounds troublesome. I’d run some of the free online anti-virus scanners to make sure she’s not infested by hackers. If she’s been rootkitted she may never know. Try to check for hidden beasties. This may take an expert to fix.
lifesazoo adds - For Christine in Ventura - multiple users - this is one possibility that might be what’s happening
It allows multiple users to be logged on at the same time and issues messages about users logged in etc.
Q Paul in Oak Hills - recording Skype calls
He does the Leoville Town Square podcast and wants to use Skype conferencing to record calls. There are software recorders like HotRecorder for Windows and Audio Hijack Pro for the Mac that can record both sides of the call on your computer. I use an outboard mixer and it works very well. I connect a studio quality mic (the Heil PR-40) to a Mackie Onyx 1620 mixer (any mixer with an AUX bus will work). I feed the mic via AUX 1 back to the Skype computer using the Griffin iMic to convert the line level into USB in. That input feeds my voice into Skype. Then I take the output of the computer (which is the Sype call minus my voice) and patch that into the mixer, also via the iMic. The main mix (my voice + Skype) goes to a recorder. (In my case I use the Firewire I/O option on the Mackie to feed separate mic and Skype channels to a Shuttle PC running Adobe Audition 2.0).

Total costs:
Hotrecorder $15
or
Mackie Onyx with Firewire I/O: $1200
Heil PR 40: $300
Griffin iMic: $40
Adobe Auditon: $300
Total $1840, PCs not included. But it sure does sound good. On the other end Steve Gibson, for example, uses an Maudio USB interface with a Heil PR-40 mic. Both Steve and I have excellent upstream bandwith - our average latency is 30ms or less. The resulting connection is 90% of studio quality most of the time. A similar setup with ISDN would cost well over $15,000 not including the ISDN line charges.
QSteve in Moorpark - antivirus for PocketPC
He has a Dell Axim X5 and wants to go online. Does he need security software? Nope.

Q Ken in Redlands - my daughter’s laptop has spyware
Her mouse stopped working, too. I’d try a USB mouse to see if it’s the drivers or the trackpad. As a listener notes below, Toshiba laptops (and others most likely) will disable the Trackpad if you press F9 - make sure you haven’t accidentally turned the Trackpad off.
As for the spyware, get Microsoft Defender and scan the system. In future, use Firefox.
QAlan in West LA - registry cleaners
I don’t recommend them. The minimal benefit you might get is way outweighed by the risk.
Q Rebecca in Encino - undeletable folder
Try these suggestions from Microsoft. And see the comments below for more information.

QMitchell in Sherman Oaks - video editing for old G3 imacs
iMovie will probably work if you can get OS X running. Visit Low End Mac for details on getting that Mac working.
QBryan in Belleville, MI - video issues on a Toshiba Satellite
First update the driver - but if that doesn’t help it could be hardware problems. In particular the ribbon cable connecting the screen to the video card tends to take a lot of wear.
QAndy in New York City - using the iBoss
His son plays flash games on a site. He wants to block the site, but some of the games are ok. There’s no way to allow parts of pages through blockers like the iBoss. The entire domain is blocked (or not). You might be able to download the Flash and play the games locally.
QSandy in Hemet - VoIP providers
She’s looking at ITP and TomatoVine.
I use Vonage and Packet8. I don’t think there’s much difference among VoIP providers. Choose by price and features.
I have a friend who loves Sun Rocket.
QMark in Santa Ana - deleting stubborn files
In Windows Mark says try Killbox. Useful for fighting spyware, too.
He also suggests turning on “Show system files” in the View options to see if there’s still something in the folder.
And he recommends Retrospect for unattended backups.
Asterisk (the amazing open source PBX software) can now be run on a Linksys WRT54G. Wow!

QBob in Banning - can’t delete file on OS X
Check Apple’s troubleshooting instructions for some useful tips.
QSteve in Havertown, PA - new video card doesn’t work
Not much to say here. Try it in another computer to see if it’s the card or a compatibility issue.
QPhil in Burbank - podcast bandwidth bills
Podcasts and internet media in general aren’t like terrestrial broadcasts, like this show. If 1,000 or 1,000,000 people listen to this show on the air it doesn’t cost KFI any more money. But every listener to the stream, or a podcast, costs money. So success can really bite you in the Internet world.
Bandwidth providers generally consider two data points: total number of bytes transferred, and the peak amount of data demand. Sometimes they only charge for one or the other. For example, this site is served by The Planet. For $250/month I get a dedicated server on a 100Mbps pipe and 2TB of data per month. If more than 2 terabytes is downloaded in a month I pay more money. Fortunately AOL and DSLExtreme serve my podcasts for free. If they didn’t I’d be paying a lot. We push well over one terabyte a day in audio content. The Planet offers me 100Mbps of data transfer at any given time - if the data demand exceeds that, too bad, some people won’t get served. My site will appear to be very slow or non-working entirely.
On the other hand some providers don’t watch the number of bytes transferred but only charge you for the peak demand. The problem with that is that most podcast clients try to download files all at the same time, so demand can be very great. We recently brought down Libsyn with our Internet TV show . 10,000 people tried to download a 335MB file within an hour or so. That means there was over 10Gbps demand - no one could serve that much data without a very sophisticated distributed server system. Companies like Limelight and Cachefly specialize in this kind of peak demand situation, but it’s gonna cost ya.

Hello Leo, last week I heard you give ideas about cell phones on airplanes. The bottom line, the big secret, the phone co’s. cannot bill you when you are above the towers. I know lots of private pilots, the cat is out of the bag, now you know… the rest of the story.
12 March 2006
How does that work with the cell phones? Why wouldn’t they be able to charge if you’re above the towers?
Suggestion: Call NERDS ON SITE.. Nation wide IT service… 877 - MY - NERDS they provide backing up off site.
Update on NERDS ON SITE: Nerds Online Backup just 1¢ per MB/mo. 30-day FREE trial!
Over a year ago, this was the best, most economical, backup solution with best customer service I found for my company after our tape drive died. http://www.backuphelp.com
Protecting new HP Laptop… before you do anything else make system restore disks! The files are stored in a hidden folder, usually on drive D. The laptop will most likely NOT come with restore disks and most people miss that until its too late. There will be instructions in the restore program about making recovery CD’s or DVD. Or you can buy disks from HP. The disks don’t actually recover the operating software, they just recover the hidden files on D and then you recover Windows from there.

Ken In Redlands should know that the trackpad on Toshiba Laptops can be turned off by pressing Function+F9
The guy with the old original iMacs can put up to 384MB RAM in them. To get all the specs go to http://www.everymac.com. I believe that you can put up to Mac OS 10.3 Panther on those iMacs because they only require a 233Mhz G3 and a Mac with a USB Port
Good suggestion on using www.lowendmac.com- the ifixit link will help on the “do-it-yourself” upgrades he needs. You can pick up some really excellent G3 iMacs on places like ebay, macofalltrades.com, or powermax.com for just a couple hundred bucks and upgrade them to be solid teaching tools. Try to get one of the faster ones- 500–600mhz, load OSX, put in some more ram and they are surprising in what they can do.
Hey leo, Crypto has to be decoded in order for it to be of anyuse. Which means that the end user of a crypto message has to have some way to unscamble the crypto. Doesn’t this mean that the crypto has somehow been decoded in some way other that through the factoring of prime numbers??
was a little confused on that technicality
Yo
Inquiring minds. I really don’t get your hatred of macs. I have used PCs all my life and I just got an 17in Intel Imac. It is so great. I admit most of the features I like are mostly just puff like Front Row, the GUI etc but at the same time I have done projects like building a website for my wedding, and editing home movies which is just easier on a mac. I know you can do all of these things on a PC but if you want to create something that works, and can be done with a short leaving curve, an Imac is a great way to go.
Inquiring Mind = Troll
The same person who’s always posting junk on this board
As a rule of thumb, please do not feed the Trolls
Caller asking for remote controlled backup:
Large amounts od date are difficult to backup over the internet. The best solution to your problem is BetterBytes (http://www.betterbytes.com/) where you have the hardware on-site but they do it for you and controlled the scheduling etc. etc.
It works very well for us (Eagle Aerospace) and I know of at least one other large software company, and another aerospace company who uses them.
They are somehow local to you somewhere in Irvine

For Steve in Havertown.
Sometimes the BIOS setting for switching over to a graphics card vs. onboard doesn’t really work. I’ve had exactly the same problem many times. My solution that has yet to fail is to actually open up the case and jumper (reset) the CMOS. I’ll even pop the battery and cross-short it to make sure everything is gone and then put stuff back and boot with the video cable attached to the video card and viola! Proceed from there to install your video drivers. You may have to go back into your BIOS to reset some of the things that the memory wipe defaults to but other than that its straightforward. Compaq and HP are the two biggest offenders as far as not sensing properly and switching over to the new card that I’ve had experience with.
Browsers.
Firefox is indeed the safest browser going I think and the features “straight out of the box” are ok, a couple of them very nice. I don’t know about the extensions available but it sounds like work to me.
For those of you who aren’t entirely satisfied with Firefox at some point of form or function, definitely stay away from IE6, but Avant Browser can be used as safely I think as Firefox IF once you’ve installed it you go under Tools and toggle off Active X and scripts for normal use and then simply toggle them on when you need them.
I’ll be very interested in Firefox 2.0 but so far it hasn’t quite measured up to the flexibility and “out of the box” features of Avant; which is to be expected I think since Avant piggybacks on IE6.
P.S. If you do check it out, you’ll also probably want to go into Avant Browser options and change the default search engine to Google—the one thing Avant gets totally WRONG!
BULL. The Avant Browser is just another skin for Internet Explorer.
Because it uses the IE engine, it is just as insecure as IE.
The only reason to use IE is ActiveX;
if you are going to disable that, get a browser that doesn’t have
the other security holes of the IE engine.

Leo! This call and responses sounded as whacky as a Coast to Coast show does at 3:32 A.M. on a Friday the 13th during a full moon! That’s the first time I’ve said that in over two years about the KFI show. Home network right? All hardwired right? I can’t make it work in my head no matter which way I go except if I bring in PARANOIA and/or DUPLICITY! I hope there’s something I’m missing besides the “jumping to collusions” obvious. I understand the concept perfectly, its the necessity I need to have explained. I have this buzz in my head filled with angry/concerned yap yap about why I’m not setting someone up with a similar configuration.
I hope you elucidate on this one or I’ll be constipated for the rest of my life!!
To Mr. Bull (rxn to 2(?) messages up),
Please read more, react less (or at least with more discerning criticisms), I covered all your arguments and more with the original statement in which I stated exactly what Avant was, its state of security compared to Firefox and who should or should not try it as well as when and where. In fact, I’ll critique myself much better—I should have more knowledge about the Firefox extensions to judge functionality truly fairly. And “piggyback;” well, that’s probably a colloquialism of some increasingly remote understanding. I’ll say “skin” next time but I won’t say disable since I come from a long line of togglers—give me something I can do on the fly without having to change cars or get out and lock the hubs and I have a much more satisfactory experience. (and I’m not saying there’s anything wrong with driving a slower, safer car—I recommend that to newer users or people satisfied with the upholstery all the time)

Brett in Huntington Beach:
It sounds like your hard drive. They can fail as a short - which causes the power supply to shut off and protect the system. I had one fail and it caused the same symptoms that you are describing. Disconnect the hard disk and see what happens. If that doesn’t fix it, I would suspect the power supply. Good Luck.

MikeHamby.com appreciates your honest opinion of any hardware or software you have tried. Leo has tested and provided support for so many different hardware and software products over the years that he has a well earned right to express some “love” for the items in which he has found merit. Say I try a new ipod, download some things from itunes, see how secure a new Apple computer is with the processing power of an intel duo core processor, I might just want to tell a friend or two about it. I just bought two new dual core processor computers, and I have been very happy with the speed that I can get things done. My ipod has great sound quality with some better Shure earplug headsets. Why bash any product if it works?
Thanks for the program. We are all being honest, Sometimes honesty hurts.
