What is the Best Linux Certification Value?

penguinA lot of people think getting certified in the use of a given piece of software is the key to an easier job hunt and higher earnings. Years ago, I knew a guy who went through a rigorous certification procedure for SAP ERP and almost immediately bumped his income from about $40,000/year into six-figure territory. Not too shabby! But today we’re talking about Linux certification, not proprietary software.

Good Sound and Poor Video is Better than the Other Way Around

220px-Bogart_Bacall_AFRSI’ve written about looking good in video chats (more than once), and about making good video in general — and doing it all with little or no cash outlay. Today I’m going to talk about sound for video, since most news video producers will tell you that good video is 80% sound. When you’re trying to get a point across, blurry pictures and clear sound beat clear pictures and muddy sound almost every time.

Is BYOD a Sneaky Way for Employers to Get You To Buy Your Own Computers?

buy, BYOD, Computers, laptop, smartphone

BYOD, AKA “Bring Your Own Device” is a big deal in the world of companies whose employees use computers and smartphones in their work. It originally came about because many workers wanted slick, new iPhones instead of the old-style Blackberries or other devices their companies’ IT departments issued. Computers weren’t affected by BYOD-itis as quickly as phones were, in large part because many employers had apps that would only run on one operating system, which limited employee choice. Still, there were workers who wanted to use a MacBook Air and run Windows on it with the help of Boot Camp. And why shouldn’t they do this? Security was one reason. But that seems to have been forgotten in this new world of Anything Goes in corporate IT.

Will Internet Neutrality Cost Us Money or Save Us Money?

FCC, Internet, Net Neutrality

I’m personally in favor of Net Neutrality — that is, having all Internet content providers pay the same rates to the broadband ISP oligopolists. And I say oligopolists because there are hardly ever more than one or two available to any given American, and often there is only one. So if you’re a content provider, like the company that runs this blog, you have no choice but to send your data to and through one of those ‘last mile’ providers. And if they want to soak you for that privilege, uh oh! There’s not a lot that can be done about it. Meanwhile, of course, the end users (me and you and maybe even a dog named Blue) are paying a monthly fee for Internet connectivity. Say what? Are the ISPs trying to get money at both ends of the pipe? Yes they are. Grrr….

Buying and Selling Used IT Hardware Takes a Shrewd Eye

bletchley_parkI recently did an interview for Slashdot with the CTO of a company that brokers used commercial and enterprise IT hardware. Some readers agreed with what he had to say, some didn’t, and a few were trolls (which is typical on Slashdot). But today, I want to talk about personal gear, and what I have to say is generally applicable to buying and selling bicycles or air conditioners, too. I’ve covered this topic before, but it’s worth looking at again.

Once Again, Let’s Talk About Cheap (but Good) Video Production

Robin Robin "Roblimo" Miller Profile: Robin "Roblimo" Miller
Aspect Ratio, smartphone, Video

corneliusLet me start by saying you MUST turn your smartphone or tablet on its side to shoot most video — and for most still shots, too. Little vertical-strip pictures are annoying in a world where we have widescreen monitors and TVs showing almost all photos and movies at a 16:9 aspect ratio, and most movies are shot in an even wider format, usually 1.85:1.

Second, lighting is important. Whether you’re shooting with a smartphone or a $5000 professional video camera, you don’t want the main light source behind your main video subject, a sin called “backlighting” in the trade. As a general rule, you want lights to show the artistic_backlit_autumn_leaves-600x412face of your subject(s). The only time you ignore this rule is when you’re going for an artistic effect, like the photo of leaves next to this paragraph — or the person you’re interviewing doesn’t want his or her face to show. And in that case, you’ll want to disguise the voice, too, which is a whole different level of complexity.

Third, headroom. I’ve mentioned this before, and I’m sure I’ll mention it again. “Headroom is a technical term, not just Max’s last name. Please keep the top of your subjects’ head at the Correct_headroom_with_zoom_gridtop of the frame, not in the center.

Fourth, not everything needs to be viewed from the height of your face. You might want to take some shots from your waist, so that the person(s) you’re shooting look especially imposing. Or you might want to hold your camera overhead to get a view from above. Now and then, you might even want to hold your camera a little off-level, although this is an effect that should be used sparingly so that your audience doesn’t think you’re incompetent instead of a fine artiste.

Back to the “narrow strip” thing. Here’s an impromptu video of Charlie Sheen shot by a fan. Think how much better it would have been if it had been shot in 16:9 widescreen, which it could have been if the person who shot it had been in the habit of turning his or her smartphone 90 degrees to take photos or videos. In fact, if this video had been shot widescreen, TMZ (or a similar gossip outlet) might have paid for it, since they’re always in the market for well-shot videos of celebrities embarrassing themselves.

‘The Savings Experiment’ Might Help You Save Money

saveThere have always been websites and blogs devoted to frugality. You’re reading one right now. But we haven’t seen a whole lot of videos on the topic of frugal technology. However, a section of AOL’s Daily Finance site called The Savings Experiment has a whole bunch of them.

Save All Around by Powering Your Computer Down is a video the site ran back in 2012 that a friend called to my attention because last week’s Cheap Computing post was titled Should You Turn Your Computers Off When You’re Not Using Them?

I like to think I got a little deeper into this topic than AOL did. Maybe that’s because it’s hard to get much information into a two minute video. It’s also possible that while AOL’s intended audience is people who wonder how to find the “Any” key, I write for technological sophisticates like you.

Still, the AOL ‘Savings Experiment,’ sponsored by Bank of America and Visa, has a lot of good tips and is worth a look or two.
394154-google-nexus-7-2013
Dial Into Savings on Your Smartphone Bill, for example. I believe I’ve mentioned a few times that my wife and I use Virgin Mobile, which gives us unlimited data and 300 minutes of voice for $35 per month per user, which is just right for us; my wife has gone over 300 talk minutes just once, and unlimited data is good because we do a lot of video work. You might want a different plan from a different carrier. The big secret is to shop — and wisely at that, which means you need to take the perky AOL spokesmodel’s advice to check your phone use habits before comparing cell plans.

One problem with ‘Savings Experiment’ is that it isn’t always accurate. For example, Surf for Savings on Internet Service says Verizon FIOS is the most expensive ISP. This may be true where their contributor Brent Hankins lives, but where I live in Manatee County, Florida, FIOS is about $50 per month and the only other broadband provider charges nearly $75. So no matter what the AOL people say — or what *I* say, for that matter — you should do your own shopping because we all have different circumstances, needs, and desires.

Still, there’s a lot of valuable ideas to be found on ‘Savings Experiment.’ Not the least of them is in this video: The Best Batteries for Your Buck, which basically tells you rechargeable batteries are lots cheaper than single-use batteries in the long run. This is 100% true — except for devices where a battery may sit for many months unused, such as a smoke detector. That’s an application where a one-use battery will give you better service than a rechargeable — and where trying to save a dollar probably isn’t a good idea, anyway.

Should You Turn Your Computers Off When You’re Not Using Them?

switchThis question has been going around and around as long as we’ve had individual-use computers, which most of us call PCs or “personal computers.” We’ve seen articles from knowledgeable people that told us to turn them off, and articles from equally knowledgeable people that told us to keep them on all the time. Who’s right? And why?

Limiting Your Subscription Services

300px-Chromecast_dongle (1)I have cable TV. I have Chromecast. I have Netflix. I am about to trade cable TV for over-the-air TV and a Tivo subscription. And Amazon Prime. That’s another $99 a year, which is enough that it shouldn’t be forgotten. What else? Phone service. Can’t forget that. My wife has a $25/month Virgin Mobile wireless plan. I have the same one, but it costs $35 because my wife got hers years ago and her low price is grandmothered in. You probably have this many subscriptions yourself — or maybe more. We need to be careful not to go crazy with all these services that look like they only cost a little. It’s easy to let them build up to the point where they cost real money.

Running Free or Cheap Android Programs and Games on Your Windows (or Mac) PC

There are many ways to run Android OS on Intel (or AMD) PCs. Most of them require at least enough geekiness to make an ISO and reformat a hard drive, assuming you want to keep Windows (or Mac or Linux) in addition to Android. But why would you want Android on a real computer alongside, say, Windows? The people I’ve talked to who want to do this typically have some favorite Android apps — especially games — they want to be able to use on their PCs, not just on their phones or tablets.
