How to Boot to Recovery Mode (Safe Mode) in Ubuntu

Sometimes, things go wrong, even on Linux systems, and you need a way to get your computer back to full functionality. On Windows, Safe Mode is usually the first choice for getting back in and fixing a problem. However, on Linux there really isn’t a direct counterpart. On most Linux distributions the solution involves using a live CD to access files on your hard drive or even use a chroot. Ubuntu has come up with a clever solution in recovery mode. It lets you perform several key recovery tasks, including booting into a root terminal to give you full access to fix your computer. Note:… Read more

Mishiko Dog GPS & Fitness Tracker review

REVIEW – A few years ago I went to take our Yorkshire Terrier outside one last time before going to bed.  I was tired and feeling a bit lazy, so I didn’t bother putting a leash on her.  Normally our dog isn’t a runaway kind of dog, but that night there was a deer in the front yard.  Like a flash our dog went after it—yes, our little dog has a Napolean complex—and the deer took off.  She circled our house once and then bolted for the woods with our Yorkie in hot pursuit.  In less than 15 seconds from the time I had opened the front door, our dog was gone.  This story does have a happy ending.  After searching through the forest for 30 minutes, our daughter stumbled upon our dog and brought her home.  We were lucky that night, but maybe it’s better not to reply upon luck.  If you have a dog with a proclivity for running away or chasing the wildlife, Mishiko has a tracker that can help you find your missing canine companion.

What is it?

Mishiko Dog GPS & Fitness Tracker is a gadget designed for two purposes.  One, it can help you find your dog when she runs away; two, it can track your dog’s activity levels to make sure she’s getting enough exercise.

What’s in the box?

  • The tracker on a collar
  • A universal fastener
  • The charging station with USB cable
  • A quick start guide and a user manual with 2 pages of instructions in English

Hardware specs

Mishiko says that their tracker is designed for medium and large dogs and for good reason.  At 2 inches wide and 0.75 inches tall, the puck-shaped device is not exactly small.  When attached to the collar, it overwhelms our little Terrier but is perfect for our neighbor’s Golden Retriever.

The tracker is powered by a rechargeable battery.  The Mishiko website says that it takes about 3 hours to charge and should last for a day or two.  The battery can only be replaced by Mishiko service center specialists.

As its name implies, the Mishiko tracker has a GPS receiver that can collect geolocation and time information from both GPS and GLONASS satellites.  When used together, a GPS receiver can fix its position anywhere in the world to within 6 feet.  The Mishiko website, however, says their device, when conditions are good, is at best accurate up to 13 feet and at worst 164 feet.  One limitation for any GPS device is that it requires an unobstructed line of sight to the satellites.  If your dog is in a mountainous area or downtown among tall buildings, then the conditions could be poor and the GPS receiver might not work very well; in fact, the Mishiko website says that it could be off by as much as 3200 feet.  Just as a point of reference, a football field is only 360 feet long, if you include the end zones.

The tracker also contains a cellular device that communicates using 2G and 3G networks.  If you’re out in the boonies where there’s no cell phone coverage, then it won’t be able to transmit its location back to you.  This built-in cellular capability is what the Mishiko device uses to automatically check for and download software updates whenever it is charging.

The device is rated IP67, which means that it can be immersed in water up to 3 feet deep for up to 30 minutes.  In other words, it should be just fine if your dog jumps into the pool or the lake while wearing the tracker.

Installation and setup

The Mishiko Dog Tracker comes in a beautifully stylish little white box.

The top slides up and off, revealing a blue interior that highlights the tracker already attacked to a collar.  My tracker and collar were both white; they are also available in black.

The battery in the tracker does not come pre-charged, so the first thing to do is to set up the wireless charging station.  It comes with a USB cable for charging, which I plugged into my Anker USB charger.

As advertised, it took about 3 hours to charge.  The tracker has a built-in white light that goes all the way around its circumference.  When charging begins, only a small part of this ring is lit; when finished, the entire ring is lit.  As a side note, when fully charged this light is surprisingly bright; one night I woke up, saw the light from my bedroom, and thought I had left a lamp on.  It’s a bit much for around the house—we started calling our dog “Lightbulb” whenever she had the tracker on—but I suppose if your dog ran away at night, it could be very helpful for finding her.

The next step is to download the Mishiko app.  The quick start guide conveniently includes a couple of QR codes, one for Apple’s store and one for Google’s.  As I have an iPhone, I simply took a picture of the correct code, and it took me to the App Store for downloading.  So easy!

Once the app is downloaded, the registration process begins.  First, I created an account.  This requires an email for the username and a password of your choice.  Second, I entered some information about our dog, its breed, age, weight, height, gender, etc. and took her picture.  Although I am only tracking one dog, if you buy multiple trackers, you can track them all in the app with the same account.  Third, I entered the serial number and password associated with the device, which uniquely identifies it.  This info is helpfully found in the quick start guide, the user manual, and on the tracker itself.  Mishiko made sure that you won’t lose this info, without which the tracker isn’t of much use.  Registration was quick and painless!

Once the tracker finished charging, it was time to attach it to the dog.  If you want, you can use the collar that comes with the device.  It’s made of nylon and has plastic clips that are functional.  The collar is quite long (27 inches), and for anything smaller than a Saint Bernard you’ll probably want to trim off some of the excess.  Keep in mind that if you want to use Mishiko’s collar, you’ll need to take off every night or two in order to charge it.  On the other hand, if your dog already has a collar that you like, you can use the universal fastener to clip on the tracker.  I’m glad Mishiko added this little feature, because it makes it easy to take the device on and off.

Design and features

The Mishiko tracker has two main features:  keeping track of your dog and keeping her healthy.

Tracking your dog

If you have a dog that likes to run away, or if you have a new dog that you’re unsure about, the Mishiko tracker can be used to help you keep track of your dog’s location.

The first feature that the tracker offers is a geofence.  You find your house on the map and drop a geofence upon it.  The default shape is a square, but you can manipulate the four corners to make any four-sided shape that you want.

Whenever your dog leaves the geofence, the Mishiko app sends a notification warning you that your pet has breached the geofence.  The default size of the square is about 500 by 500 feet.  On our street, this square is large enough to cover not only our yard but five additional yards in both directions; in other words, it’s a huge geofence.  Shortly after setting up a default-sized geofence, I got an alert.  Our Yorkie had already run away!

Then I looked down and saw that she was sleeping on her bed right next to me.  Unfortunately, this was not the only false alarm that I got.  Every day I get a few more alerts, and every time the dog is right where she belongs.  This feature is a bit like the boy who cried wolf; it has happened so often that I simply ignore it.

To make matters worse, it’s just as error prone the other way around.  In other words, when I intentionally took the dog on a walk outside of the geofence, sometimes I got an alert, but other times I did not.  There seems to be about a 50-50 chance that the app will tell me that my dog has run away.  Sadly, I think the geofence feature is simply too unreliable to be of any use, which is too bad, because it’s a great idea.

The second feature that the tracker offers is the ability to find your dog once she runs away.  Since our dog doesn’t really run away—we couldn’t find a deer to help us out—we had to “help” her run away.  My wife put the dog in the car and drove off without telling me where in the neighborhood she was going.  I waited several minutes for the geofence alert to warn me, but sadly it never did.  Finally, I just turned the app on and looked at the map; indeed, my dog was no longer near our house.  I hopped into my car and set out to find her.  The good news is that this functioned exactly as intended.  Although the app doesn’t give directions like Google Maps—turn left on Main St—it perfectly overlaid both my position and the dog’s position on the map.  All I had to do was keep my icon moving towards my dog’s icon, and eventually, I found her.  Given Mishiko’s statements about how inaccurate the GPS might be, I was a bit concerned that the app would get me only sorta close to my dog but not really close.  I’m happy to report that this wasn’t the case; it was accurate to within a few feet.

After finding the dog in our neighborhood, my wife drove off again and took the dog out of our neighborhood.  I waited a bit and then tried to find her.  Even though she was a few miles away, the app had no problem leading me right to her, to the dog, and (conveniently) to a Starbucks.  This is really good to know:  If your dog runs away, the Mishiko tracker can take you right to her.

Keeping your dog healthy

The Mishiko tracker can be helpful if your dog runs away, but it’s also useful even if she never leaves your neighborhood.  It can track the health of your dog, ensure that she’s getting enough exercise, and give you some hints about diet.  It’s kind of like a Fitbit for dogs.

When I began using the app, one of the first things I did was run an assessment.  It’s a week-long evaluation of your dog and how much exercise she’s getting.  When finished, the app gives a diagnosis.  For my dog, the diagnosis was “Your dog has a normal body condition.”  Based on this diagnosis, the app helps you to keep your dog healthy in two ways.  It’s worth noting that the manual says the app works best for dogs that are one year or older, so if you have a puppy, it might be a bit off.

The first way the app keeps your dog healthy is by making sure that she gets enough exercise.  The tracker and the app measure how much exercise your dog has already had each day and how much more she needs to get (or stay) healthy.  You can press the “Start a walk” button, and it will track your path, the number of steps taken, the distance walked, and the total time of your walk.

In fact, this app keeps track of a lot of statistics about your dog, which you can find on the Statistics page.  It’s quite fabulous, except for one detail:  Its measurements are sometimes wildly inaccurate.  If you look at this next screenshot, you’ll see that it says that our dog walked 7.1 miles yesterday.  The problem?  Our dog never left the house that day, except when she had to “go” outside.  We didn’t take her for a walk that day; we didn’t even play fetch with her.  (We were pretty bad owners that day, weren’t we?)  Did she walk 7.1 miles?  Not a chance.  It’s unlikely she even walked half a mile.  There are lot of days when the statistics showed wonky values like this.

The second way the app keeps your dog healthy is by recommending good dog food to eat.  Some dog food is healthier than others, so if you enter the type of food that your dog is eating now, it can recommend better food.  Unfortunately, this part of the app looks like it’s not quite done.  It only recognizes a very limited set of manufacturers.  We use Hill’s Science Diet, a very popular brand and one recommended by our vet, yet the app didn’t recognize it and recommended that we switch.  Given the links to buying food from within the app, it feels more like a way for Mishiko to make a little extra money than it does a source of great recommendations.  On the other hand, there is some useful information here.  For example, it teaches you how to gradually change from an old dog food to a new one, something that is especially helpful for dogs with sensitive stomachs.

Overall the app looks nice; the interface is simple and intuitive.  There are, however, a few wrinkles that still need to be ironed out.  If you look back at the screenshot for the Statistics page above, you’ll see that “yesterday” is listed twice; every day is listed twice.  If you look at the monthly view below, you’ll see that it says February at the top, even though it’s actually March (and even says March on the bottom).  These aren’t critical bugs, but they seem like mistakes that should have already been caught by their software testing process.

What I like

  • Rechargeable battery and wireless charger
  • Uses GPS and cellular service, giving a broad range tracking
  • Rated IP67 for water protection
  • Great ability to find a runaway dog

What needs to be improved

  • False alarms for the geofence
  • Inaccurate calculation of our dog’s level of exercise
  • Small bugs in the software

Final thoughts

The Mishiko Pet Dog GPS Tracker leaves me conflicted.  On the one hand, I think the primary value of this device is to find your dog when she runs away, and it does this very well.  On the other hand, there are several things that just aren’t working right.  This gadget has a lot of potential, but for most people, I recommend waiting a bit to see Mishiko can fix the problems.  If, however, your dog likes to run away, and you’re concerned about losing her, then it’s probably worth buying.

Price:  The basic option is £49.99 (~$67) plus £4.49 (~$6) per month after the first month.  Other options are also available.

Savor the savings with Kroger Pickup’s clickable coupons

ARTICLE – Kroger Pickup (formerly ClickList®) offers super-convenient grocery shopping and virtual coupon clipping.

If you’re a Kroger Rewards member, you can log in to Kroger.com, and by selecting “Start my cart” it will display suggestions based on your recent purchases.

They also have a tab for “My Sale Items” to show you which of your usual go-to’s are on sale at the moment.

Plus, whenever you come across an item that’s offering current store or manufacturer coupons, you can add the coupon by simply checking a box. For bargain shoppers like myself, it’s priceless! I certainly won’t miss clipping coupons the old fashioned way and then half the time forgetting to bring them or else taking them with me only to discover they expired yesterday.

The drawback is, unlike Walmart grocery pickup, for example, Kroger charges $4.99 per shopping trip. However, with online coupons and offers, you can often make up that five bucks pretty quickly. Plus, your first three orders are free, and they’ll sometimes send you coupons for free pickup here and there after that.

Similar to other grocery curbside programs I’ve used, you select a one-hour window to gather your goodies. Also, you can click which items you will accept substitutions for in case they’re out of stock (and you can accept or reject those substitutions at pickup time).

When you arrive, there’s a designated parking area for drive-up customers. And you simply call the displayed phone number to let them know you’ve arrived and which parking stall you’re in.

The Kroger site offers a few nice bonus features, too.

First, you can add comments. So, for example, I like hard avocados so I can use them later in the week when they ripen. I can let my personal shopper know my whims and wishes, and so far, they’ve done a good job fulfilling my requests.

Secondly, the site offers suggested recipes, and if you want to try one, you just click “Shop Ingredients” and all the needed items pop up.

Since we shop at Kroger already, my family has some established Kroger-brand favorites (like their popcorn and string cheese), so this has been a hugely convenient option, especially when we’re having a busy week or gathering up supplies for another Friday sleepover. Plus, like all Kroger shopping trips, we earn those nifty fuel points.

Armadillo USB Firewall review


REVIEW – I can remember when floppy drives were the craze and then CDs and DVDs all with increasing capacities and abilities. In recent times, our demand for storage capacity and portability has resulted in USB flash drives and portable hard drives becoming the common use norm for storing and sharing files. I have come across a few people who were in a desperate position because they used someone else’s USB drive and accessed a file that was infected with a virus. In other cases, they managed to transfer an infected file from a computer to their USB drive. The result was anywhere from a small and relatively easy to rectify difficulty all the way to having to format their drive and reload their OS. In many cases, they would lose files that they failed to back up. The Armadillo USB Firewall offers protection against this type of disaster and more.

What is it?

The Armadillo USB Firewall is a high-speed USB firewall that connects between any computer and your USB device, isolating malicious firmware and keeping your computer safe. It can be used for flash drives and portable hard drives where its high-speed USB 2.0 hardware enables quick file transfers.

What’s in the box


1 x Armadillo USB Firewall
1 x User Manual
1 x Micro USB

Design and features


On one side there is a “Read Only’ mode switch that allows or restricts the data passage between two-way and one-way writeability and the micro USB jack that allows you to connect to your computer.



Shown below is the opposite side of the Firewall that has the standard USB port to plug in the portable USB drive.


Performance

The Armadillo USB Firewall is pretty much plug-and-play, and its use is quite simple. Place it in between your USB portable drive and your computer and it will protect your computer and your USB drive from malicious software that can harm your computer files. The “read only” switch allows you to prevent any malicious files from being written to your storage device. Engaging or disengaging this switch requires you to unplug the firewall from your computer and then switch the mode and reconnect. It is also important to note that the firewall only supports drives up to 2TB in capacity.

The picture below shows the firewall connected between my 2TB encrypted drive and my laptop.

What I like

  • Build quality
  • Portability

What can be improved

  • The quality of the “read-only” switch. It feels a bit cheesy.
  • The firewall should have the ability to switch modes without unplugging and reconnecting each time
  • The limitation of up to 2TB drives since larger drives are now readily available and commonly used

Final thoughts

If you use USB drives on your computer from various known or unknown sources, this is a useful device to ensure that your computer and your drive are protected from malicious files/software. This is not a device for anyone who uses their own files and never shares drives, but for many of us who do, it is helpful. It is somewhat expensive and could be more efficient. The decision to purchase this firewall device is a personal choice and in my opinion, should be based on how exposed your computer and USB drives are.

Price: $249 NZD = $171.06 US
