Who Sent the Email?

Here's a tip that might be helpful occasionally. If you receive an email that, for some reason, looks a bit suspicious, or has an attachment (a possible source of a virus) you can find out who it's really from by clicking "show original" per the instructions in the following link: http://www.isipp.com/resources/email-headers/

The instructions vary, depending on which email client you use. I checked this out in Gmail, and it works. This could save you from getting a virus from opening an attachment in a suspicious email.

Closing Apps in iOS?

,

If you're using an iPhone or iPad running the iOS operating system, should you close an app after using it, or periodically close all apps that you've opened during the day? Here are two articles that say no:

https://www.komando.com/happening-now/409554/one-mistake-you-should-never-make-with-your-apps-when-trying-to-save-battery-power

https://daringfireball.net/2017/07/you_should_not_force_quit_apps

Prior to reading the above I had thought that apps, once used, remained running in the background and consumed a slight bit of operating memory. Apparently this is no longer true. Background apps, it seems, are 'frozen' and no longer consume operating memory.

This is good to know, and I'll not worry about closing background apps.

iPhone X

 My wife and I recently purchased the iPhone X and, I must admit, we do like it -- including the unlocking of the phone with facial ID. The following article explains more about this feature, which will be of interest if an iPhone X might be in your future. 

This article comes to us courtesy of Don Mayer who, with his wife, are owners of Small Dog Electronics (http://www.smalldog.com/). This is a good place to shop for Apple products -- competitive in price and a very helpful staff.

Let's Face It By Don Mayer 

I have had my new iPhone X for a couple weeks now and it is magical in so many ways. Being an old codger, it is truly future shock to be holding such a powerful device in my hand and one that instantly recognizes my face, too! There have been a lot of stories out about Face ID and my first-hand experience is that it just works. It is transparent and I lift up my iPhone and it is unlocked. Contrary, to JoJo’s report a few weeks ago, it is not just black people that it has trouble recognizing in the dark, I have to enter my passcode on occasion when I lean over in bed to see what stupid notification I got at 2AM.

What You Need to Know About Face ID

Apple’s new iPhone X does away with the Home button, which has been a fixture since the original iPhone and has long served as the Touch ID fingerprint sensor. To replace Touch ID, Apple developed a new facial recognition technology called Face ID. With Face ID, the iPhone X scans your face to authenticate you instead of using your fingerprint. It is truly amazing technology! Apple even invested in the company making the scanning lasers that make Face ID work this week.

How does Face ID work?

Freaking Magic. Well, almost. As science fiction author Arthur C. Clarke said, “Any sufficiently advanced technology is indistinguishable from magic.” Face ID is cutting-edge technology that uses Apple’s TrueDepth camera system to project over 30,000 invisible dots onto your face. Then it illuminates your face with infrared light and takes an infrared image. Finally, it translates that image into facial recognition data that are encrypted and stored within the iPhone’s Secure Enclave (the data never leaves your iPhone). Face ID updates its mathematical representation of your face overtime to keep up with how your appearance changes.

5322.jpg

How secure is Face ID?

Extremely. Apple claims that Touch ID’s false positive rate—the number of people who would have to try logging in to your iPhone before someone would succeed randomly—is 1 in 50,000. In contrast, Apple says that Face ID’s false positive rate is 1 in 1,000,000. It can’t be fooled by a picture or a simple mask, although a high-enough quality 3D reproduction of your face might get past it, just as a sufficiently good cast of your fingerprint could fool Touch ID.

However, Face ID has trouble distinguishing between identical twins and siblings who have nearly identical features. So if you have an evil twin or even a nice twin with a sick sense of humor, stick to a Touch ID-based iPhone or your passcode! The probability of an incorrect match is also higher with children under 13, since their facial features haven’t become sufficiently distinct yet.

By default, Face ID works only when you look at the iPhone X—it can’t be unlocked by your face when you’re sleeping or in my case when I am staring at my Mac’s display with the iPhone on my desk.

How fast is Face ID?

Not quite as fast as Touch ID in current iPhones, but fast enough that you likely won’t notice. When you pick up your iPhone X so you can look at it, Face ID will, in most cases, have already recognized you.
This quick recognition is possible in part because the iPhone X can start scanning early, thanks to iOS’s Raise to Wake feature and a new Tap to Wake feature that automatically wakes the iPhone X when you touch the screen.

5321.jpg

What if Face ID doesn’t work?

First off, things like wearing a hat, scarf, or glasses won’t confuse Face ID, nor will growing or shaving a beard. Thanks to that infrared camera, it even works in complete darkness, sorta. It does seem to have more trouble working with black people in the dark or maybe even darker skinned people. However, Face ID does fail occasionally. One reason for a Face ID failure is holding the iPhone X too close to your face—this is easy to do accidently if you’re nearsighted and not wearing your glasses. (Some sunglasses prevent Face ID from seeing your eyes, but you can work around that problem by disabling Require Attention for Face ID in Settings > Face ID & Passcode.)

To make Face ID retry a facial scan, hold the iPhone X at a normal viewing distance, tilt it away from you, and then tilt it back to your normal viewing position. If that doesn’t work, or if you want to let someone else use your iPhone, enter the passcode. Entering the passcode is always an option.

Alas, unlike Touch ID, which let you enroll up to five fingers (so family members could unlock your iPhone without using the passcode), Face ID lets you have only a single face.

Can I use Face ID for anything besides unlocking?

Oh yeah, Face ID completely replaces Touch ID, so you can use it to authenticate when you’re using Apple Pay, or the App Store or iTunes Store. Plus, apps that previously relied on Touch ID, such as the 1Password or LastPass password managers, will automatically use Face ID instead.

We hope Apple can make the hardware necessary for Face ID cheaply enough to bring it to other devices as well. Wouldn’t it be nice if you could walk up to your Mac and have it automatically unlock because it had recognized your face? Now, if it could just read my mind and do my work for me I’d be all set!

Hotspot Shield VPN

An interesting observation. At our condo our wifi is secured so I don't really need to use a VPN. A VPN will typically slow down one's connection speed, because of encryption, decryption and distance to the VPN server. Out of curiosity, just now, I checked my download speed, and it was 35 mbps -- perfectly usable, and I'm on Cox Cable.

Then I opened Hotspot Shield VPN (just playing around) and did the speed test again -- 58 mbps!  Surprising, but quite nice. I ran the test again and got 52 mbps. So the server for Hotspot Shield (somewhere in the U.S.) was faster than Cox Cable's server. 

I've noticed a slowdown in download speed at home (CableOne) and at our condo (Cox Cable) depending on when I'm on the internet -- faster in the mornings and slower in the afternoon when more people are on the internet and available bandwidth seems to be soaked up.

When on public wifi (RV parks, airports, restaurants) I always use a VPN to prevent snooping on my computer or iPad. Typically I don't use a VPN on our secured wifi networks, but from time to time I'll check a VPN (I have several) just to see what the connection speed is.

Now, no big moral to this story -- just an interesting observation.

Brydge Keyboard

Recently I purchased the new 10.5" iPad Pro, and really enjoy it. A very nice device. At the same time I bought the Apple keyboard that is made for this iPad. I've used it for a couple of months, it works, and overall I'd rate it just OK -- serviceable but nothing special. The keyboard is not backlit and is a bit awkward to use. Plus, folding/unfolding the keyboard was a bit of a pain.

I read a review of the Brydge Keyboard for the 10.5" iPad Pro, and the author liked it much better than the Apple keyboard. So, today, I bought one at Fry's Electronics, and I also like it much better than the Apple keyboard. For starters, it has a backlit keyboard, and types so much better than the Apple keyboard. It is Bluetooth, and paired quickly with my iPad.

The keyboard does add a bit of weight (about as much as the iPad), but gives the iPad the use and feel of a small laptop computer. How often to charge the keyboard? Oh, about once a year. Not too onerous. So, if you should buy (or Santa brings to you) a new 10.5" iPad Pro, I highly recommend the Brydge Keyboard. The following link shows one on Amazon.

Apple's Tax Payments

Recently, and from time to time, there is an article about Apple not paying enough taxes, or about the huge amount of cash Apple has overseas, and doesn't bring home to the U.S. An Apple blogger -- Kirk McElhearn -- has written an article expressing his views on the subject:

https://www.kirkville.com/apple-and-the-facts-about-apples-tax-payments/

If you read the article, also read the comments, which Kirk addresses individually.

Lots of different opinions expressed. Whether what Apple is doing is 'fair' or 'right',

I believe they try to follow the laws of the land in each country they operate in. For example, Apple received criticisms for removing access to VPNs in China at China's request. Not because Apple wanted to, but because the Chinese government asked them to.

iPhone X

Here is a review of the iPhone X by Kim Komando, a noted tech blogger:

https://www.komando.com/tips/427914/iphone-x-unveiled-kims-trusted-opinion-do-you-get-what-you-pay-for

One thing to note is the scratch on the phone after only a few days. She didn't drop the phone, but carried it in her purse. I've read several times it's very important to get a case to protect this phone, and a clear plastic shield for the face as well.

The more I read about the iPhone X the more my interest diminishes a bit.

OLED vs. LCD

The new iPhone X has an OLED display. And, as you've probably noted, the iPhone X is a bit pricey due, in part, I'd guess, to this new screen. Is OLED worth the extra cost? If you want improved battery life, the answer is yes.

The following article explains more about the two screen technologies.

Amazon Web Services

Here is an interesting article by David Pogue about a company that you may not have even heard of: Amazon Web Services. It is, for many companies, the ‘cloud’. Watch NetFlix? Comes from AWS. And so it goes for many companies. The article says that AWS is even bigger than Amazon. Read below.

Inside the Amazon company that's even bigger than Amazon.com David Pogue  

Oct 25th 2017, 19:39

Everybody knows what “the cloud” is, right? It’s, like, internet storage or something? Sure. Yeah.

I wanted to go a little deeper. I wanted to know exactly what it is, where it is, who owns it, who runs it, and how it works. So I did a little travel, conducted some interviews—and last Sunday, “CBS Sunday Morning” aired my story. You can watch it here.

The “who runs it” part has a particularly interesting answer. In large part, the answer to that is, “Amazon” (AMZN).

Over the last decade, Amazon has quietly built up the world’s largest cloud-services company, called AWS (Amazon Web Services). In terms of income and profit, it’s much bigger than Amazon.com (the division that sells stuff by mail-order).

It’s also much bigger than its rivals, which include Microsoft (MSFT), IBM (IBM), and Google (GOOG, GOOGL); in fact, AWS says that it’s bigger than its next 14 competitors combined.

Most companies don’t like to reveal what cloud-services company they use, but here are a few companies that don’t mind saying that they run on AWS: Hulu, Netflix, Comcast, Spotify, Pinterest, Yelp, Airbnb, Slack, PBS, SmugMug, Hertz, Time, Intuit, Unilever, Zillow, Dow Jones, Morningstar, Under Armour, Kellogg’s, Expedia, Adobe, Philips, GE, Shell, AOL, BMW, Canon, Capital One, IMDb, Johnson & Johnson, Lamborghini, Lyft, McDonald’s, NASA, Novartis, Pfizer, Philips, Samsung, SAP, Sony, SoundCloud, Ticketmaster, and the US Department of State.

For the TV story, I had the rare opportunity to interview an Amazon executive: Dr. Matt Wood. His current title is general manager for artificial intelligence AWS, but he’s been part of AWS from the beginning. (I asked him if the “Dr.” meant medical doctor or PhD doctor. In Wood’s case, both. He started his career as a medical doctor.)

As always happens, though, the time constraints of TV meant that not all of the good stuff from our interview made it into the broadcast. So here, for your reading pleasure, is a more complete edited transcript of my interview with Dr. Wood.

tumblr_inline_oyeajsQkxu1spvpit_540-1.jpg

Dr. Matt Wood (right) joined me for a “CBS Sunday Morning” interview at Amazon’s Seattle headquarters.

POGUE: Because AWS caters to businesses, not ordinary consumers, most consumers haven’t heard of it. But it’s giant, right?

WOOD: It’s a relatively large business today. We’re a little over $16 billion in revenue run rate [projected income for 2017], and we’re growing at just over 40% a year.

POGUE: So who had the foresight, when AWS started, to say, “You know what could be really a good business for us…?”

WOOD: It actually came out of Amazon retail. The developers inside Amazon retail wanted to be able to move more quickly. They were frustrated about having to write big checks [to buy new server equipment] and wait and wait and wait [for them to be delivered], and do all this extra work to be able to try out their idea.

And so we started to come up with some ideas about how we could make that faster. And so we started to explore an entirely new business for us, selling these services to businesses in the same way as Amazon was consuming them.

POGUE: So all of these companies are hiring AWS to do what?

WOOD: They are able to pull down computational power as if it was a utility.

So let’s say you’re a brewery, right? They don’t want to manage computers. They want to brew beer. They don’t want to be going through the expense and the upfront cost and all the complexity of managing these large amounts of computers.

POGUE: So it sounds like cloud companies like AWS are basically renting computers, storage, power, security—all the stuff that technicians would have normally had to do on site, right?

WOOD: That’s right, yes.

tumblr_inline_oyeajsXjwy1spvpit_540.png

AWS relatively unknown to consumers—but it’s by far the largest piece of Amazon.

POGUE: Are you also saying there was a time before cloud companies when people did all this stuff in house?

WOOD: Yeah. People often talk about the “heavy lifting” of building web applications or mobile applications. Well, back when I was doing my Ph.D., we were given the task—a group of Ph.D. students—to move a mainframe computer from one room to another.

This thing weighed — it must have been several tons. It took about eight wimpy nerds to try to lift it. We dropped it, and it got stuck in the doorway. (LAUGH) We had to get the university football team to come in and help us move it out of the way before our professors came back and found us!

POGUE: (Laugh) Literal heavy lifting!

WOOD: So it’s not like that today. All I need is an AWS account and a credit card, and I can start trying out new ideas, for pennies.

And larger organizations find the same benefits. And so today, very large organizations such as, you know, GE, Shell, Phillips, Netflix, all run on top of AWS.

POGUE: Really? Netflix?

WOOD: Yes.

POGUE: Wait. Amazon has a very similar business—Amazon Prime Video. Why would Netflix hire its arch-rival to store and serve up its movies?

WOOD: Well, that’s a good question. It’s one that Netflix asked us very early on. (LAUGH) From the very first day of AWS, we set up the company as a separate business. We have a separate management chain; we are situated in a separate building.

We even wanted companies that could potentially compete with Amazon.com—our cousins at retail—to be able to use the same platform. And so to AWS, Amazon.com is just another customer.

POGUE: Is there a downside to the cloud idea? Is there any reason that somebody might shy away from structuring their data this way?

WOOD: The only reason I can really think of is that some companies have already made those very, very large investments in their own data centers. They’ve signed the checks, they’ve done the waiting, they’ve racked and stacked their service. And so they’ve already made that investment.

POGUE: So suppose I’m one of these companies who’s got an existing computer setup, and I want to move to AWS…

WOOD: Yeah. There’s a couple of ways that you can do that. You can just upload it as normal. But sometimes you have so much data [that it would take forever to transmit electronically]. So we built this device–the Snowball.

(He shows me a suitcase-size, gray, plastic-enclosed case.)

tumblr_inline_oyeajtkFLl1spvpit_540.png

The AWS Snowball can be a faster, cheaper way to send a company’s data to Amazon than uploading it.

POGUE: Snowball, you call it?

WOOD: It’s 100 terabytes of storage. And you just connect this up to your data center, load your data on. And then you just physically ship it back to us, and then we load it into the cloud from our data center.

POGUE: Ship it, like through FedEx or UPS or something—

WOOD: Exactly. You should never underestimate the bandwidth of a FedEx truck. (LAUGH) In fact, right on the front here, you can see that we have an e-ink display—basically, a Kindle—which shows the customer’s address when we ship it out to them. And then as soon as they arrive and plug it in, [the address on that screen changes to show] our data center collection location, and you just ship it back to us.

POGUE: Oh, this—this is a screen, this is not paper—

WOOD: Exactly, yes. Because we didn’t want the shipping labels to come off in transit.

POGUE: So essentially, this is like a giant shippable hard drive. Can you track it?

WOOD: Yeah; it has 3G, Wifi, and also a GPS system.

POGUE: But hard drives are delicate. What if the shipper guy drops it?

WOOD:  We built them to be robust and ruggedized. We actually built them to military specifications. We put them on a boat in the middle of a lake and then exploded depth charges around the boat and then made sure they could still work.

POGUE:  Can it handle a drop to concrete?

WOOD:  Easily, no worries.

POGUE:  Like this?  (I shoved the Snowball off the table onto the concrete floor, where it just bounced and then lay flat) It’s okay, folks! It doesn’t have a scratch on it. I don’t know about the floor, though.

WOOD: (LAUGHS)

How AWS handles security

POGUE: OK, we gotta talk about security. I imagine you have a huge staff of experts?

WOOD: Yeah. I mean, security really is job zero for us. We take it extremely seriously. It’s the first thing that we think about when we get up in the morning, it’s the last thing we think about when we go to bed.

POGUE: Because “the cloud” actually resides in data centers—huge, unmarked buildings running thousands of servers. And one AWS data center may house the livelihoods of a bunch of companies, all concentrated in one building.

WOOD: Actually, we don’t even store all of the data in one place. We don’t have a single data center. We use groups of data centers. And those groups of data centers are separated by large distances. They’re on separate floodplains and fault lines. We move data automatically between the data centers in those groups. And that means the data is always backed up, not just inside a data center or between data centers, but between groups of data centers in different physical locations.

POGUE: So I don’t mean to give anyone ideas, but let’s say I figured out that one of these unmarked buildings was an AWS data center, and I blew it up. Are you saying that it’s so backed up and redundant that you probably wouldn’t notice?

WOOD: Yeah, you wouldn’t notice. I mean, we might be a bit upset, but you wouldn’t notice.

POGUE: That leads into my other question, which is that 70% of the cloud, 70% of the world’s internet traffic, flows through data centers in Loudoun County, Virginia. Should we be worried about that concentration?

 

tumblr_inline_oyeajv02bF1spvpit_540.jpg

70 percent of the world’s Internet data flows through the massive data centers in Loudon County, Virginia. (CBS News)

WOOD: No, that data is backed up across multiple different physical locations. And we do that to limit the blast radius. If something does happen, or we have a power event, or there’s a flood in one specific location, that data is held redundantly in other locations, as well. So the cloud just keeps running.

POGUE: How is each physical AWS data center protected?

WOOD: The first thing is that we control personnel extremely tightly. So although I’ve been at Amazon nearly 10 years, I’ve never visited one of our data centers. I’ve never stepped foot inside them. I don’t even know their addresses.

POGUE: Because you’re not allowed to?

WOOD: Because I’m not allowed to, yeah. I don’t have any reason to be there. And a data center’s primary vector of insecurity is physical attacks. So you don’t want people there that don’t need to be there.

Beyond that, obviously we have all of the controls—the concrete, the guards, the bars—to prevent and mediate and evaluate physical access to the security. If you don’t need to be in there, you don’t get in.

POGUE: One of the data center managers told me that one reason we’ve never heard of terrorists attacking a data center is that they’re interested in terror—and that’s attacking people, not things. That a data center is just a bunch of machinery that’s easily repaired and replaced.

WOOD: Easily repaired, easily replaced, and can cause no disruption whatsoever.

POGUE: What about hacks? You know, Equifax, Sony, and other big companies being hacked. Does that have anything to do with the cloud and the way it’s structured?

WOOD: Only in that we provide developers the tools to prevent these sorts of attacks. So you can go in and very quickly protect all of your data. You can encrypt all of your data. And we even provide machine learning tools that evaluate the risk associated with your data.

So we can identify, with customers’ permission, a difference between a webpage, which is OK to deliver, or Social Security numbers and personally identifiable information. And then we continuously monitor for differences in how that data is accessed. And if we find an anomalous access, then we alert both automatic remediation and people, so they can go investigate.

POGUE: Then how do these hacks happen?

WOOD: In a variety of ways. The most common way is social engineering—trying to figure out someone’s password through nefarious processes. So calling up and saying that you are the telephone operator and you’re asking for their password, for example, and then the person just giving it to you. So it’s much more common for those sorts of attacks to be propagated.

POGUE: So the weak link turns out to be us.

WOOD: As it so often is.

Record Voice Memos on the iPhone

The article in the link below describes how to use 'Voice Memos' to easily record something on your iPhone. You don't even have to look to find the app on your iPhone. Pick it up, hold the Home Button till Siri opens, then say " Siri", "open Voice Memos." The app will open and you just tap the big red button and start talking.

This looks to be mighty handy to make a quick note of something you don't want to forget.

This works on the iPhone 6 and newer models. And it works on the iPhone 5 if it is running iOS 7.
