Watch Tracy from California Comments

Tracy is going on a backpack trip in France and Spain soon and she wants to know what size memory cards and how many of them she should bring for taking pictures. Leo says that he's often torn between the convenience of one large card and the security of several smaller ones. But Leo says having enough cards so she doesn't have to erase them is a good idea. If her camera can upload images to her phone for a backup, so much the better. The key, though, is to swap out cards often and offload them to a computer or the cloud. Leo doesn't delete the images off his card either. Then he can use the cards as a backup to those that have already been offloaded.

What about video? Leo says video will run about a gigabyte an hour. So a 32 GB card will give her a lot of video. She should shoot short, six to ten second clips that she can mix with stills. It's plenty to trigger her memory. The good news is that microSD cards are cheap and likely about 5-10 cards at 32 or 64GB would be more than enough.

Chris Marquardt says to treat cards like film. If she would've brought 20 rolls of film, then bring 20 cards.

Watch Marty from Los Angeles, CA Comments

Marty wants to publish some software but he's worried about someone being able to back engineer his software by decompiling the code. Leo says that so-called "obfuscation" is a technique used to prevent such things, but unless he's creating software that is so magical and game changing that he needs to resort to it, it's not really anything to worry about. Remember that obfuscation makes it harder for the coder to write as well. The easier way to do it is to use non obvious names for his objects in the code.

Watch Richard from Southern California Comments

Richard can't do a backup -- it just stops. Leo suggests running "ChkDisk" to see that everything is OK with the data. But Leo also says that Microsoft's backup program isn't all that great because it dumps all of the data into one giant furball of 1s and 0s. That means it has a single point of failure. And there's no way to know if it has it all of the data or not.

Leo prefers just backing up all the critical data (like images, video, and critical documents) and copy them straight over to a hard drive. He can use Microsoft's SyncToy. it's great to run as a synced backup.

Watch Louis from Los Angeles, CA Comments

Louis just got back from a cruise and he has a ton of videos. But when he backed up his images and videos to his computer, the videos didn't sync from his iPad. Leo says that the issue is that Windows PCs handle media over Wi-Fi differently.

The Chatroom says that Picasa may not be able to see the folder. He should also try syncing each video manually, since it requires so much bandwidth. He could also sync with a wire instead of Wi-Fi, as that should certainly work. Apple has a tech note on this issue at There's also an article at that suggests a fix.

Watch Doug from Idaho Comments

Doug has been using Magic Jack for his business. Leo says that's a good choice for smaller use, but it's important to remember that VOIP is always dependent on the quality and bandwidth of the internet connection. Also, there's latency as the packets often come out of order and must be reassembled. Leo uses a business solution, RingCentral. But for a sole proprietor, Magic Jack should work fine.

Doug also wants to know why he can't plug a USB key into his camera and download images directly. Leo says that the challenge is that USB is not a peer to peer system. There's a hierarchy, and that's why a USB drive can't connect to another USB port without a computer in between.

Watch Bob from Austin, TX Comments

Bob got a message in Safari the other day that his browser was "depricated." All he's been told is that he should update to OS X Yosemite or El Capitan because it will include a version of Safari that has WebKit, which many websites rely on. Leo says that could work, but if his hardware doesn't support Apple's latest OS, then it becomes a money grab by Apple when they abandon this older hardware. Then again, Apple doesn't fall into the end all be all trap that Microsoft fell into for a long time. Sometimes, developers have to move forward and leave older platforms behind. Everyone has gone to WebKit and it's going to happen more often. Upgrading isn't a bad idea if the computer will support it.

Watch Bob from Albany, NY Comments

Bob recently upgraded an old Dell computer to Windows 10. He did an upgrade, which didn't work, then tried a clean install and it worked flawlessly. So he's quite happy to breathe new life into an old PC. Bob also likes the new backup and recovery feature. Leo says that Microsoft finally has backup down, and it's as good as Apple's Time Machine. He also says that Windows has profile based language support, so you can change languages by changing profiles, including Cortana.

Watch Monica from Diamond Bar, CA Comments

Monica uses two monitors on her computer, but when accesses her work's VPN, it only supports one monitor. Is there an option for her? Leo says that Microsoft Terminal Services Client can be forced to use both monitors by adding "/span" to the command line shortcut on the desktop that looks like this: %windir%\system32\mstsc.exe /span. She can also do it in her settings. The chatroom also says that if the monitors have different resolutions, that can cause issues as well. Another thing to check is to see if the Windows license permits it. Windows Ultimate will, but home won't.

Watch Angelo from Rancho Cucamonga, CA Comments

Angelo feels like he's being ripped off after hiring a devloper for an app. All he got was a step by step on how to create it, and not the app itself. Leo says that may be the first step - a paper mockup of what the app will be and how it works. It's called a "functional specification." But if they want more money for that, it may be time to look elsewhere. The hard thing is, when just starting out, you don't know what to look for in an app developer.

Some good options for hiring programmers include Stack Exchange, eLance, and Fiverr. And since WhatsApp was bought for $22 Billion, app developers are charging a lot more these days. And frankly, Leo doesn't know the answer other than to learn how to code.
