Understand Jargon to Be a Smarter Consumer


Every community has its jargon, but when you are entering into a new world of products and services, it is important that you understand the lingo so that you don't end up purchasing something you don't want or need. Many consumers are prone to making impulse purchases without thinking. In fact, 75 percent of Americans have made impulse purchases and 16 percent said these purchases were over $500, according to a survey by Being knowledgeable about what you are dealing with makes you a smarter consumer. Here's a look at some jargon you need to know:

Cloud Computing

Cloud computing and data storage isn't just for businesses — it helps you preserve and save precious photos, videos, and other data from being lost. However, much of the terminology is new and confusing. For example, you probably want to look for a “consumer cloud” service, which includes popular services like Dropbox. If you want to save as much money as possible, advertising-based pricing models tend to be cheaper. But if the idea of having to look at ads to run your apps turns you off, don't use this type of discounted plan. Consumption-based pricing models refer to services that charge you based on the amount of data you use, rather than a subscription that has set limits and prices per month. Now that you understand some of the technical terms, decide which type of service is best for you.

Surround Sound

If you've ever been wowed by the dynamics of surround-sound systems in movie theaters or home theater stereo systems, you may want to have a system of your own installed. Understanding how surround-sound systems are labeled is essential if you want to get the right one for your home. For example, what does 5.1 surround sound refer to? Well, the five refers to the number of channels: two in the front, two in the back and one in the center. The one refers to whether or not the system has a subwoofer; a one means it does, a zero means it does not. The Dig points out that surround sound comes in a variety of set ups, such as 7.1 and 5.1.2 (which means there are two height variable stereos that add depth to the front soundfield). There are countless variations on this formula, but when you understand what the decimals stand for, you have a better chance of getting what you want and not spending more than you need to.


Biking is a popular way for people to get around in urban areas or add some exercise to the daily routine. Some biking terms can be counter intuitive, though, so make sure you understand them before you buy one. For example, clipless pedals refer to a style of pedal that actually has clips that attach to your shoes to hold your feet in place. The type of pedal with a strap is referred to as a “toe-clip,” so clipless is a reference to them not being this style of pedal. This is the sort of thing that confuses many new bikers (I know that first-hand, since I started cycling a couple of months ago), so it helps to know the jargon before you go into the store. For more of this sort of jargon, Road Bike Rider has an extensive glossary.

One other comment on jargon - don't be shy about asking what these things mean. Sure, you run the risk of some body trying to make you feel dumb, but most of the time I've found that people are willing to help you understand their jargon. For example, bike shop employees should be willing to explain the differences between a Schrader valve and a Presta valve - if they give you a hard time, find another bike shop.

eBike technology from Bosch - hands-on

A couple of weeks ago, Bosch eBike Systems brought an eBike out to me so I could try it out. What's an eBike, you ask? In technical terms, an eBike is a bicycle that has been augmented with an electrical assist that provides supplemental power while you pedal. In practical terms, it is an impressive tool to help you simplify your commuting or road cycling jaunts.

Bosch doesn't make the bikes - they make the "mid-drive" systems that are built into the bikes, so you can find different types, sizes and styles of bikes to fit your needs and preferences. You can find out more and locate a dealer near you at the Bosch eBike site. [Note: I receive no compensation or other consideration for this - just a free ride on an eBike].

Mount up...

I was riding a Haibike XDuro Trekking RX bike with Bosch Mid-Drive technology (provided by Cynergy E-Bikes, a local Portland company), and it was my first time riding an eBike. 

The bike looks a lot like a typical hybrid bike (built for road cycling, and off-road friendly), and I immediately noticed the weight - it was noticeably heavier than the bike I typically ride. That extra weight is because it has batteries on board, and the frame has been reinforced to handle the forces of the electrical assistance mechanism - the Bosch system is built in during the design of the bike, not bolted on afterward, so it is quite sturdy.  

Once on the bike, it rode and handled very well - it felt like a normal commuting bike, and it took no time at all to get acclimated (and it didn't feel very heavy from a rider's perspective). 

Becoming Superhuman

I rode for a couple of miles near downtown Portland, in a big loop along the Willamette River promenade, which gave me a chance to experiment on flat, straight sections as well as some good inclines, congested areas, and curves. The bike was a lot of fun to ride and I found myself thinking about what it would be like to own.

The real fun started when I turned on the eDrive -- I felt superhuman! It is hard to describe the feeling you get when you turn on the eDrive and the bike begins to surge forward, accelerate, and climb up challenging hills under the assistance of the eDrive.

The way Bosch's eDrive system works is by multiplying your power so every pound of pressure you exert on the pedals is amplified when it reaches the wheels. There are 5 modes:

  • Off:     no assistance from drive unit
  • Eco:    50% assistance from drive unit
  • Tour:    120% assistance from drive unit
  • Sport:    190% assistance from drive unit
  • Turbo:    275% assistance from drive unit

You can change modes on the fly, smoothly and without interrupting the ride. That means you can spend most of your time in Eco, but kick things into Turbo for a killer hill or to make up some time on the road when you're in a hurry.

When choosing modes, keep in mind that the more assistance you get from the eDrive, the faster you use up the battery's charge. For example, depending on conditions, the range in Turbo mode (highest assistance) is 20-40 miles. In Eco mode (least assistance) the range is 50-100 miles. The on-board control panel tells you how you're doing and estimates remaining range based on how you're using the bike.

These bikes do need to be recharged, as they don't recharge while you are riding. That said, they last quite a while - you should only have to charge the bike once or twice a week if you use it for commuting, and the recharge time is about 3 hours (you just plug the bike's charger into a normal household outlet). If you run out of power on the road, you won't be stranded - you can simply pedal it as you would a normal bike (though the additional weight may make pedaling a bit more difficult on hills without the power assist).

Who are eBikes suited for?

While anyone would enjoy this bike, it is ideally suited for commuters, as well as people who are less physically adept but want to ride in hilly terrain (or more easily keep up with more accomplished riders). Bosch says these systems are very popular with the 50 years and up crowd, since they like the physical assistance the bikes provide and typically have more disposable income to justify the extra cost (eBikes typically cost about $1500-2000 more than comparable, conventional bicycles).

Commuters will likely appreciate these bikes most - imagine riding 10 miles to work on an eBike and arriving at work without feeling like you need to take a shower; that is possible with the assistance of the eBike power drive. If you get the chance, stop by a local bike dealer who stocks eBikes, and give it a try - I think you'll be impressed.

Apologies for site issues and kudos to


Some of you have sent me emails, messages, etc. over the past few days regarding this site being offline. I apologize for that, but have good news: everything is back to normal now.

Yes, was down for about a week due to a snafu at my domain registrar. All should be fine now, and you'll see some posts showing up here soon (I have a backlog).

Kudos to Hover

Part of the solution to my issue drove me to change domain providers. I have heard a lot of good things about Hover in the past so I decided to give them a try. Actually, I've been an email customer of theirs for a long time - I bought a vanity email from a company called NetIdentity in the mid-90's and Hover acquired them at some point. I've been very happy with the email service, but just never had a compelling reason to move my domains there until I had this outage.

One of the things I liked about Hover was that I was able to just hand the problem to them using their "Valet Transfer" service. I gave them access to my old provider's account and they went through all of the steps to unlock and transfer my domains to Hover, as well as configuring my settings on Hover to restore service.

This was amazingly easy, and I highly recommend using the valet service. They charged my $9.95 per domain to do this work, but also extended each of my 7 domains by a year.

On top of that, some of the services I used to pay extra for at my old provider (rhymes with GoDaddy) are now included in Hover's service (such as domain privacy, protection from unauthorized transfers, etc.

If you're looking for a great domain provider, I can recommend Hover without reservation. And no, I don't get any compensation from them - I just think they are a good company to work with.

Sharper Minds Through Video Games?

I play a lot of video games during my travels - it is a great release to unwind in my hotel room, and I find it very relaxing (yes).  I flit from one to another quite often, but my current favorites are Borderlands 2, Diablo III, and Call of Duty: Black Ops.  I also tend to apply lessons I learn from video games into how I view the world; for example, I have given multiple talks about what information security can learn from video games - such as this brief talk the RSA Security Conference earlier this year).  

With that in mind, I wanted to make sure I wasn't deluding myself - to find out if there really is something to this "learning from video games" thing I preach about all the time.

According to the Entertainment Software Rating Board, 59 percent of Americans regularly play video games, with the industry earning more than $10.5 billion in revenue annually. The survey also showed 44 percent of respondents play video games on their smartphones and 33 percent play on wireless devices. The rise in popularity of gaming has also led to the rise of studies investigating the potential negative effects they have. The Ohio State University found an increase in violent video game playing resulted in a spike in aggression.  

For what it's worth, I can definitely tell the difference between video games and reality and I think this resultant increase in aggression might be true of any competitive activity, such as organized sports.  Of course, that is just my theory...  

Since I know I benefit from playing video games and I don't feel they are harming me, I was curious about the "other end of the spectrum" when it comes to the impact of video games.  As it turns out, more researchers are looking into how video games can benefit us and report surprising results. Boosting memory, delaying cognitive decline and increasing multitasking ability and confidence are just some of the ways we can benefit from regularly playing video games.

Boost your memory

Recent studies from the Georgia Institute of Technology show gaming won't necessarily improve reasoning and problem solving, but can help boost your memory. Working Memory Capacity (WMC), is our ability to recall information relatively quickly even while distracted. The study showed that gaming can help strengthen our memory skills, along with our ability to work on a variety of tasks or switch between them quickly.

That makes sense, since practice with just about anything - including retention of data - tends to improve your abilities in that area.

Prevent cognitive decline

Playing games and using the computer may help prevent cognitive decline and preserve brain function. Staying mentally and physically active — whether by socializing, exercising or playing games — could also delay the onset of Alzheimer’s. Game resources like iWin carry a variety of puzzle games and mind teasers that could help strengthen memory, improve hand-eye coordination and encourage problem solving on convenient mobile devices or tablets.

I used to play Brain Age on my Nintendo DS to help in this area, and I know people who swear by Sudoku and other puzzles as a way to keep their memories and minds sharp.  I say you enjoy it and it doesn't cause any harm, why not?

Improve Multitasking

Researchers at UC San Francisco discovered video games, especially 3-D varieties, can actually improve overall cognitive performance in older, healthy adults. Senior citizens who played the games for 12 hours over the course of a month showed an improvement in working memory and sustained attention. Their ability to multi-task also improved as they became more skilled at switching focus during their gaming activities.

Of course, we can't truly "multi-task," but the better we can context switch and get back on our mental feet when switching from one task to another, the better.  I've noticed that my eyes take longer to adjust from close vision to far vision as I get older, and I suspect that resistance to switching from one context to another is a challenge from a mental perspective.

Build Confidence

Scientists at the University of Essex explored if people's self-esteem improves while gaming because it gives them the chance to experiment with characteristics they envision their ideal self possessing. The Researchers discovered gamers enjoyed gaming the most when there was little overlap between their actual and ideal self. Participants reported feeling better about themselves after playing with the personality traits they wanted, such as being outgoing.

I definitely agree with this.  Even though it is an artificial world, I find that taking risks in video games makes it easier for me to take risks in the real world - it can help you feel less anxious in the face of the uncertain.

Improve your vision

While some say excessive video gaming can hinder your eyesight, some new studies show the opposite to be true. Researchers at the University of Rochester discovered action video gamers who play a few hours a day over a month improved their vision by 20 percent. This improvement came from being able to pick out letters from a clutter of images. Gamers played for about 30 hours and saw a significant increase in their vision's spatial resolution.

Again, this feels right to me.  Not only do video games improve my reaction time, they force me to expand my attention to take in more things - this is true from a visual point of view, but also from an overall situational awareness perspective.  I need to keep tabs on where I am, how I'm doing versus my objectives, how the others in my party are faring, pay attention to new threats and opportunities, etc.

The bottom line

OK, so maybe I'm guilty of contrived rationalization, but in my book, the data says playing video games is good for me.  Enough said - I'm sticking with it!

[Updated] SpiShutter hands-on - a great webcam privacy solution for MacBooks

A while back, I shared how you can use cellophane tape to keep people from spying on you with your webcam.

For the past month or so, I've been using an alternative called the SpiShutter which I really like so I wanted to share it with you.  Here is a brief video walk-through showing how it works:

I have the black version of the SpiShutter, but they come in a couple of other colors, as well. 

By the way - the privacy screen I mention is the 3M Gold Privacy Filter for MacBook Pro Retina computers - they are available for most other computers, as well.  That's meant for a different kind of privacy - namely, to combat shoulder surfers and neighboring travelers - and I swear by them.
