Android

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).

Warning: If your device uses WiFi, it's at risk!
News broke today about the Krack Attack, a new cyber threat that can decrypt and potentially view everything users are doing online. The Krack Attack preys on a weakness in WPA2 protocol. Hackers near the vulnerable devices (Android and Linux are at greatest risk) can retrieve sensitive user data and information.
Steps to Protect:
1. Apply patches as they become available. For phones and computers, the patches will come in the usual update format. For wifi routers, the manufacturer's website will have the patches.
2. Don't use public WiFi, especially for sharing or sending any sensitive information.
3. Double check that you are browsing with HTTPS. If you are unsure, install this plug-in to encrypt your communications with major websites and make your browsing more secure. https://www.eff.org/https-everywhere
4. Otherwise, use Ethernet.

An article in today's paper headlines that "New Apple Devices get mixed reviews"  

Some bullets:

1. Apple products have gotten bad reviews in the past, only to go on to sell like hotcakes.
2. Most reviewers think the Apple iPhone 8 is OK at best and feel people are waiting for iPhone X. There may be something to that.
3. Most reviewers appear to think the Apple quality is basically intact.
4. Most reviewers thought the Apple visual design was old and Samsung design is cool.

So what will I do?

I had a Blackberry, upgraded to an iPhone 4s, barfed at the size of the 6s Plus and purchased an iPhone SE which is a 6s in an iPhone 5 (not 5s) case.  When it was introduced, it was the fastest smartphone on the planet - BIG battery and SMALL video.

So I do not need to upgrade to iPhone 8. My SE is now running IOS 11 quite happily.  

My phone works. I do not care whether it looks cool. At least it does not melt.

If you haven't switched to the latest plan with your carrier, you might be overpaying / being gouged.  Earlier this year I investigated what Verizon had to offer and found out I was paying waaaay too much money.  After collaborating with family members we got 5 of us signed up under one plan and are saving hundreds of dollars a month now.  Family plans save $$$ folks.  And the plan differences between each carrier are not that drastic either.  Verizon and AT&T reign supreme.  Yes, more money, but you have superior service over the cheaper carriers.  Whoever is your carrier, do yourself a favor and take the time to see if you're overpaying and switch plans asap.

I think we're paying about $150 for 3 phones on the unlimited plan, but I'd have to double check.  We could be on some old pricing promo, too.

I think AT&T was also advocating for Net Neutrality's removal, but they didn't spend anywhere near as much as Verizon and Comcast.

If you're an app developer (iOS or Android) and want to add facial recognition to your app for free, then you may want to take a peek at ZoOm. Maybe Experts Exchange will add it to their nifty little app.

Side note: You won't be able to use it to replace the fingerprint reader on your iPhone. I too was excited by the prospect of swapping one biometric for another, but sadly it doesn't have that function.

Interesting... I've seen the rumors that Apple is already planning for the iPhone 8 to use facial recognition for unlocking the phone. Wonder if they'll expose that in their dev APIs for other apps to use and how that'll affect FaceTek.

Oh man, I hope they didn't lower it to 5mph.  I hadn't heard that on Silph Road yet.  Last I remember folks there were saying the speed cap was 11mph.  People who use bicycles for transportation were throwing a fit about the 11mph.  

It does a check every 2-5 minutes, and bases how far you go off of that.
Yes, exactly.  There was a glitch I ran into, and others confirmed it as well, that there is a way to incubate eggs in the time that the calculations are being made where all of a sudden the eggs would hatch (2.0km ones) without even being walked!  I think they eventually patched that.

I also have the problem where my connection switches between 3g and LTE so often that it's always getting disconnected and not registering the location changes as often as it should.  So half the time (or more) when it tries to do that location check it doesn't register any changes.  It seems to know where I am on the map, but it's losing its log of how far I've gone or something.

I was running long distances (1-3 miles) in a straight line and barely getting 1k before I stopped playing.

"Subject of the week | What are your favorite smartphone apps?"
Having recently switched from a Blackberry to an Android phone, I am discovering a whole new world of apps. However the main apps I have used so far other than social media are Gasbuddy for finding the best fuel prices, and Fuelly for tracking my fuel consumption.
I have also been looking into an application called Torque for live tracking of vehicle performance data, but have recently changed cars and want to see if it will still do what I want. In fact may even write an an article about that once I get it set up properly.

I am learning about a new interesting app every time someone is posting.  For sure I will try some of them.  I also remember when I moved to Sao Paulo (population 12 million) / Brasil I had to buy a huge, heavy book with the city directory, with the street maps. Sometimes to find a place it was a complete nightmare.  Nowadays, with google maps, it would be a dream.

Do you remember the explosion of SAMSUNG Galaxy Note 7 last year? It is the only smartphone which is not allowed to bring on an airplane.

In last month, SAMSUNG Galaxy Note 7 has been relaunched in South Korea and its name has been changed to SAMSUNG Galaxy Note FE (Fan Edition).

Will you buy it?

Great explanation! I've been a fan of the Note series since the very beginning and I hope they've learned their lesson with the Note 7 because I don't see myself having another type of phone. I totally understand the competitive pressure with Apple and it's this competitive spirit that drives technology to improve (some improve more than others, ha!).

Another reason why Note 6 is skipped is Samsung Galaxy S6 is a failure from not even matching the sales of S5 and number 6 is an unlucky number and regarded as one of the taboos in C level executives of Samsung and is omitted from future smartphone naming except entry level product.

An active Android-focused spyware family called SonicSpy has burst on the scene after being found lurking within 1,000 mobile apps, some found in Google Play.

Lookout Security researchers Michael Flossman found that SonicSpy can manipulate a victim's device via 73 remote instructions, including the ability to silently record audio, take photos with the camera, make outbound calls, send text messages to attacker specified numbers, and retrieve information such as call logs, contacts and information about Wi-Fi access points.

I have worked with many smaller businesses from professional offices, universities, regional home builders, remodeling companies, insurance, small teaching studios, hospitals, and retail.   A couple of things that really stands out for those that are successful are focusing and going all in.    

For any of these that tried something by testing the waters with a toe dip, they end up failing and never had a chance of success.  For any that went "all in", there was success.  

I worked with 3 start ups that branched off from the same place to go on their own.  Two where gun shy, didn't put enough effort into marketing and ended up blowing whatever money they did put in. The third acted as if they were taking over the region and their marketing efforts reflected that.  This company went to $10MM in sales within a couple of years.    Probably closer to home for many, try taking Google's offer for free initial $100 in PPC ads and keep that budget for a few months.  Your going to fail.  Now try to dominate in your market and for many micro local businesses, that is going to mean spending $1,000 to $5,000 monthly on PPC.  Assuming they have a good system to keep people in the funnel moving towards a sale, they will succeed.  There is a point where you are just pissing into the wind throwing your  money out and no return.  

With many of these Google products, to the outsider, it feels like they do not go all in.  Inbox for instance.  It's a nice front end, but you can't use it 100% as is, you have to use the gmail interface.  Google+, I feel was not focused. They tried to do too many things at once with it.  A business was forced to have a g+ account, which took over for Google local and that alone was very confusing.  I did not like that aspect of it, but did enjoy the groups that were for development. It was a good way to learn about new items.  

My point with Google is, if they are going to put something out, go all in or go back to labs and say it is not a full fledged product yet and may never be.  When it is ready to come out of beta/labs, then go all in and dominate like they have the ability to.  Instead, it feels like they throw a bunch of stuff against the wall to see what sticks with no conscience to those that tried to adopt.

Typing on mobile: some thoughts

I was thinking the other day about smartphones and how I often don't like to type on them. I'm just so used to typing on full-size keyboards, that typing on mobile is like swimming in molasses. And it's really a shame, because in so many other ways, my iPhone is incredibly convenient.

But then, I thought about how speech to text these days is pretty decent, and perhaps the best approach would be to just use Siri for dictation instead of trying to type. I've held off on such things, because I'm old enough (and had enough bad experiences with flaky computer dictation long ago) that psychologically, it feels really weird to talk to a computer.

But in this case, my computer is a phone.

And that means: I feel weird talking to a phone.

Which is kind of weird, don't you think?

What about you? Do you type on your smartphone a lot? Or do you use Siri/Cortana/Google for dictation? Does talking to your phone feel weird or is it totally normal for you?

Stacy: I'm curious... Why do you hate talk to text?
Not speaking for Stacy, but I too get frustrated with 'Siri' sometimes, especially so if I'm driving and try to initiate a hands free call to some of my contacts. I tend to drive with my windows fully down almost all year round so I guess the ambient noise probably doesn't help, but it can be incredibly frustrating when two out of three calls tend to work perfectly!

A typical example goes something like this..
1. Hey Siri, call Tom Smith, office..  "Calling, Tom Smith.. office"   Tick! - Successful call
2. Hey Siri, call Bob Jones, mobile.. "Calling Bob Jones.. mobile"  Tick! - Successful call
3. Hey Siri, call Jennifer Clayton, office..  "Calling John Mechanic, office.."  Huh?!?!

Might take two or three attempts before she finally gets it right and I've had to explain myself a few times when not paying much attention to Siri's answers (which most times I'm not) and the call goes through to someone I had no intention of calling.

One amusing time she wrongly called my dental surgery and I ended up making an appointment for a routine checkup during the call. Turned out I needed a filling so that call ended up costing me about $150.00!! lol..

I'm sure others must have also experienced this phenomenon as well? :)

One reason of not liking talk to text if you ever been on the end of the message that has not been read over before sending is really confusing and can cause some problems.

Second reason just listening to someone use talk to text is simply annoying to me. I don't want to hear the conversation you are having.

This is just my opinion.
