For a couple of months, the audio of today’s show is here. Recent shows are here.

The intro and outro music was by Pentatonix.

Paul was in the studio and Glenn called in.

Paul started off talking about how KVMR’s Community Calendar is displayed on his screen as he reads it. He said the way a screen appears is determined by markup not layout. Layout is more concrete and deals with things like how many inches and pixels and point size of text. Markup is a more general and determines how the elements of the page relate to each other — for example, H1 text is bigger than H2 text with out saying the exact size. He then introduced what’s called ‘responsive web design’, which makes a webpage readable on a small phone screen or a huge monitor.

Glenn saw the movie Aquaman the other night, He thought it was a pretty good movie and was impressed with some of the technology used in making it.

Paul found the Battery University website extremely interesting. <See the link above>. Going on he said that Lead-acid batteries (as in a car) leak current between the plates and will eventually become discharged, if they are left to stand unused. They also supply a tiny amount of current to the car’s radio so it can remember the preset stations. The car battery will not “do well” if the charge peak drops below 85% or 90%.

Paul bought a small solar panel of about 15 watts from Harbor Freight. He hooked it up to a battery to provide a trickle charge to make up any loss in charge from standing around for a long time. It’s perfect for his RV that doesn’t get much use. However, he cautioned listeners not to connect solar cells directly to a battery. It should first go thru a regulator.

He said “the peak natural voltage of a lead-acid battery that’s not being charged or discharged is somewhere around 12.7v”. So, from China you can get an LED display that will tell you if the battery needs charging, if it’s at peak charge or if it’s busy charging. He noted that if the alternator in the vehicle goes bad, it can pump too much current into the battery and damage it. <Presumably, the LED display will warn you about this.>

Recently Glenn had the battery in his iPhone replaced for $29.95, under a special program Apple created. The program covers the iPhone 6 and later. In later iPhones go to ‘Settings’ -> ‘Battery’ to find out how much capacity is left. If it’s below about 80%, it’s time to think about replacing it, Paul said. If you replace the battery yourself or have it done by a third party, the battery won’t be as good as one furnished by Apple. The Apple battery will give you the best service lifetime — 80% capacity after about 3 years or 1000 charge cycles.
<The special Apple program was mentioned during the 1-10-18 and 10-24-18 shows>

Glenn has noticed that his refurbished iPhone 8 has been using up the battery at an unusual rate. Last Wednesday it went from 100% to about 16% in about 6 hours, without using it much. If it continues, he said he’ll have a chat with Apple. He thinks he may have turned on some feature that used a lot of current. Paul suggested he go to settings and find how much of the battery each app has used. In ‘Settings’ you can use the search box to find ‘battery’. He said IOS 12 and possibly IOS 11 has this search feature.

Glenn thought his mail service might been what was using up his battery. Paul suggested using ‘battery saver’ mode, which can be found the battery menu. This mode will suppress the push notifications from Skype, Facetime, email, etc.

When the guys went to the Apple Store at the Roseville Galleria to get the batteries replaced, they got the chance to examine a Tesla 3. It’s $47,000 out the door with up to $10,000 in rebates. But the federal rebate may be going away, Glenn said. The dashboard was very simple, just a 17″ touch screen display.

It has 7000 batteries similar to those in a laptop, probably NIMH Paul said. They are arranged in a big rectangle under the floorboard. And is has 4 electric motors, one in each wheel — the area under the hood and the trunk is available for storage. It comes with a charger and there are 10,000 charging stations in the US. The greatest distance between charging stations is 160 miles. The Tesla’s range is about 270 miles.

Paul chimed in to say that it takes 30 to 40 minutes to charge up at a charging station, which uses a high current that you won’t get at home. At home it will take about 10 hours using the standard 110v & 15 amps. 240v and 30 amps takes about 5 hours. Check with your utility as electricity rates can vary with the time of day.

In Asia and maybe Europe, Hyundai & Kai have a car similar to the Tesla in features with 310 mile range for $30,000. It will be available in the US some time this year, Glenn said.

The other question Paul asked the Tesla rep is what happens if you get stuck between the charging stations. He was told that Tesla has a charging truck that they will send out to juice up the battery. You should get plenty of warning before you run out and the navigation system will direct you to the closest station. Glenn vaguely remembered that Tesla offers free charging at their stations for the first 6 months.

Backtracking a bit, Glenn said having the battery replaced out of warranty is $49 for those with an iPhone 5se to the 8 Plus.

Talk turned to downloading videos from Youtube. There used to be plugins for Firefox and Chrome to download Youtube videos. But Youtube doesn’t want you to download so they tweak their service to discourage it and those plugins don’t work anymore. They’re not updated often enough to keep up with the changes at Youtube.

The site youtubnow.com lets you paste in the link to the Youtube page of the video you want to download and it gets the video for you to download.
<Though I haven’t used these for some time, keepvid.com is similar to the above. And the Dentex Youtube Downloader is an app for mobile (The apk is here)>

WebM is becoming a standard for streaming media. It comes from a consortium of companies like Youtube, Facebook, Microsoft, etc who wanted a royalty-free format that can play in HTML5. If you download a WebM video you’ll have a file that ends in .webm, which you can then play using VLC (Videolan). It’s a free program that will play many video and audio formats.
<More about Webm here>

Paul added that Youtubnow works with sites other that just Youtube. And it can extract and download just the audio.

If you have an older Mac to re-purpose with an Intel Core Duo, or Intel Core 2 Duo CPU, which are 32bit processors (later processors are 64bit), and as long as you have enough memory, you can boot and run Windows on it. You can buy a license key for Windows 7 from Microsoft. Or you can install it without a key, in which case it will nag you a lot. Or you can burn (on CD) a copy of Linux Mint, which is free.
<Linux Mint was mentioned in the 3-25-15 show>

Paul also mentioned DVD Styler for Linux and Windows (and possibly for Mac). It’s free and is used for burning DVD movies with many interesting options like making it start to play a some point other than the beginning.

For a couple of months, the audio of today’s show is here. Recent shows are here.

The intro and outro music was by Pentatonix.

Both Paul and Glenn were in the studio today.

Paul started by talking about copyrights. On Jan 1 2019 for the first time in more than 20 years, copyrighted works will enter the public domain, which means the their copyrights expire. This is because 20 years ago the length of copyright protection was extended from 55 years to 75 years.

Public domain is different from Creative Commons and open source. Open source software can be amended by someone who isn’t the original author to create what’s called a fork of the original program.

A fork resulted when Open Office, a suite of programs similar to Microsoft Office, became Libre Office — “a more dynamic system, which had more updates and more features”, Paul said. He uses Libre Office because it’s “evolving somewhat faster”. The latest software suite that Paul found is WPS Office. <All are free. See the links at the top>.

Glenn reminded listeners that they can call in with their questions or comments during the show. The number in the studio is 530-265-9555. Or they can send email to zen at kvmr dot org.

Also, Glenn noted that for every donation to KVMR thru 12-31-18, Incredible Pets will donate 5 LBS of pet food to Nevada County Pets In Need. Go to kvmr.org to donate.

Paul said that registered non-profit organizations can go to techsoup.org to download legitimate versions of operating systems, like Windows 7, for very low cost. They will also be able to get the 2016 version of Microsoft Office. This is for 501C non-profit organizations.

Coming back to WPS Office, Paul said that it will automatically recognize .doc & .docx files and save in those formats too. It can dynamically produce .pdf files as well as open .pdf files to be read. WPS Office comes out of China, he added.

Paul went on to say that he’s been using Google Docs for a long time. With it you’ll can open .doc files and save them in the native Google documents format. So you don’t need to install software to handle .doc files that you get elsewhere.

You can upload .pdf files to the Google Docs directory <you’re given storage space for your documents.> And if the .pdf contains a graphic of some text, Google can perform OCR (optical character recognition) to extract and create plain text. He said he’s only been told this and hasn’t tried it yet.

Glenn said he’s been using pdfescape.com, which is free, to edit .pdf documents while online. He also noted that there’s free software called PDF Creator. Paul said “it becomes a print driver so you can print to a printer called PDF Creator”. Glenn said if you want to make a .pdf out of a webpage, for instance, it will “print” the page out to a file instead of an actual printer. You can then treat it like any other .pdf file.

With PDF Escape, Paul cautioned about uploading sensitive information you don’t want to be generally known. <That’s true for most situations where you’re working online.>

Paul said that in Apple’s IOS 12.1.2 the screen can light up and act like a flash when taking a picture with the front camera (the one pointing at the user, as in a selfie).

Paul talked about the situation where you have many tab open in your browser and you need to shut it down or restart your machine. How do you get those tabs back? If you are using Firefox, go to the 3-stripe icon in the upper right, go down to the cogwheel, find “restore previous sessions” and check the checkbox. There’s a similar option in Chrome in the settings menu.

Marilyn called. She has migrated to a machine with Windows 7 from Window XP machine. XP converted her 2002 Microsoft Office .docx files just fine but “it will not convert on my Windows 7”, she said. She has “to take it over to the XP computer, convert it and then bring it back”. <She installed Microsoft Office on the Win7 machine from the original CDs.>
– Paul said that there is an addon that allows an older version of Office to read newer versions of Word documents (.docx). The addon has to be downloaded separately, and he’s not sure it’s available anymore. It might be at oldsoftware.com. <I think he may have meant oldversion.com> Paul did a quick search and found what’s called Microsoft Office Compatibility Pack for Word, Excel and PowerPoint 2007 file format.
– Be sure you end up on the Microsoft site when you search for this kind of stuff or you may end up downloading something malicious.
– Paul thought she can try a converter — try the WPS word processor.
– Glenn suggested she save in the older .doc format rather than .docx. That also makes it easier to share the document with others who might have trouble with .docx.

Paul explained what’s special about the x in .docx. Microsoft decided to use the xml markup specification. Inside the .docx document is a template that that reports where all of the resources are (where the pictures, graphics, fonts, formatting are). You can experiment with a .docx file you’re willing to lose. Change the file name with .docx to .zip and unzip it. You can then pull out the contents, like fonts, he said.

One of the things Marilyn tried was to save her documents in an older format (2003). It was an .xlsx doc and it saved to an .xls file, but she still couldn’t get the Win7 machine, with Office reloaded from a CD, to open the file. Paul thought she needed to install the Office service packs on the Win7 machine. Google the words: latest service pack for office 2002. If it comes up saying it’s service pack 3, you may need to install the previous service packs (1 & 2) first. Installing Office from the CD onto her Win7 machine means its no longer able to update itself from Microsoft Updates, so she has to do it manually. In Word on the Win7 machine, go to Help -> About and it will say Microsoft Word 2002. If it says nothing else, no service packs are installed. If it says SP1 or SP2 or SP3, then those service packs are installed.

Glenn did the disclaimer:
The opinions expressed on KVMR are those of the speaker only and not necessarily those of KVMR management, staff or underwriters.

Paul had a tip for those needing to find the key for the software installed on their machine, like Microsoft Office. This might occur if you’ve lost the CDs. Go to belarc.com to get the free Belarc Adviser. It will tell you all sorts of info about your machine, including the keys use to install various software.

The guys raised the point that WPS Office comes from China and there may be fear of being spied on. Paul noted that everybody, including the US, spies on everyone else, and that it’s good to be suspicious of software no matter where it comes from. But he doesn’t mean to imply that WPS is malicious. You can get it at wps.com.

Glenn talked about how he saves passwords. He uses keywords like the word ‘home’. He gave an example where the word ‘home’ would refer to the street number of his first home, and he wants to use the number as the password. He then creates a contact for, say, KVMR, and he’ll enter ‘home’ in one of the fields. Now, if he needs to remember his password to log into KVMR, he’ll pull up the contact for KVMR. see the word ‘home’ and be reminded that the password is the number for the address.

Glenn said the new Apple IOS creates very a secure password. It asks you if you want to store it on your keychain. With the keychain all you need is your Apple ID.

Paul said Apple no longer sends you email to reset your Apple ID, they use security questions now. Be very careful how you answer those questions, he said. When Paul sets up answers for the security questions he doesn’t use capital letters or even use spaces between words. He doesn’t use punctuation and tries to keep it short. This makes it easier to remember — he doesn’t have to remember if he capitalized his father’s name, for instance.

Paul doesn’t seem to like third part utilities to handle passwords like One Password. He doesn’t know how trustworthy or secure they are. The company can be hacked and your password compromised.

Dana called. His screen died and someone gave him an ASUS monitor as a replacement. But it says “splendid demo” on the screen and it doesn’t go away.
– Disconnect it from the computer. If it persists, then you won’t be able to get rid of it.
– It won’t go away until a valid signal comes across.
– Unplug the monitor, shut down your computer, then reconnect the monitor, and start the computer. Then the operating system can determine the resolution of the screen.
– Windows 7 (what he’s using) and the monitor talk to each other thru a protocol called One Wire.
– Start Win7 while holding down the F8 key. <Paul didn’t seem to finish the thought>.
– If there is no wording on the screen when booting up the computer, then they aren’t talking to each other. Pull the connector out of the VGA socket and check the pins. Some may be bent.

Dana said it’s annoying to have “splendid demo” on the screen along with the game he’s playing. Paul apologized for assuming that nothing else was being displayed. That means another round of trouble shooting, but they’ve reached the end of the broadcast. Paul is going to look into it some more. And at the very end he found a Youtube video on how to deal with it. <Maybe he searched for the words: ASUS splendid demo>.

For a couple of months, the audio of today’s show is here. Recent shows are here.

The intro and outro music was by Pentatonix.

Both Glenn and Paul were in the studio today.

Paul spent some time talking about converting VHS videotapes to a newer format. There is a device available that can extract the video as it comes thru the left & right audio and the yellow composite video leads. This device costs 6 or 7 dollars and plugs into the USB port of the computer & the other side has the inputs for the 3 leads that come from the VHS player or video camera. You’ll end up with an .mp4 or .mpg file. These are compressed video file formats that are generated at the rate of about 1 gig for every hour of the original video.

You can then upload a video to Youtube and set it as being private so it’s not visible to just anybody. If you want to allow someone to see it, you can just send them the Youtube link.

On the other hand, you can’t just burn one of these files to a DVD disk. It may play back on some computers but most will fail.

Some Macs have IDVD that allows you to author these disks.

Paul has a friend who converted videotapes to DVDs. There wasn’t much content on each DVD so he asked Paul to combine everything onto a single DVD. He was given 10 DVD disks each with about 30 minutes of video.

When you open a DVD you made yourself (a generic DVD, not one you bought at the store), you’ll find a folder called video_ts. By the way, DVD stands for digital versatile disk, not digital videodisk and is meant to be a large capacity storage medium on which you can store any file. Though it never caught on, there is a format for storing audio on the disks and they would be stored in the folder audio_ts.

So you open the DVD and in the folder video_ts and you’ll find many files, some ending in the letters ‘vob’. You can double click one of these files and play it in a player like VLC. These files are video files in the format of mpeg2 (motion picture experts group type 2). Some of the other files are additional information that let you skip around and move back & forth in the vob files while you’re playing them. Without this additional info, you won’t be able to move the slider button and the time indicator may show a bogus value.

Paul tried to edit his friend’s video to cut out the blank areas and found that a special program was needed. One is called Handbrake, which works on the PC, Mac and Linux. You first have to convert the vob files into something else. Paul chose .mp4. The .mp4 is a highly compressed format that you can put directly on your website. When a modern browser using HTML5 displays the webpage with the link to that file and the user clicks on the link, the browser knows how to play the video.

Another way to get usable video off of the DVD is with an extractor like FFMPEG Native. It’s a very versatile program that can convert between many formats. The drawback for some people is that it’s a command line program. Like the good old days of DOS, you type in the instructions that you want the program to execute. It’s not to bad in this case. You can type ‘ffmpeg -i filename.vob output .mp4’, where filename.vob is the file you’re converting. <I’m guessing that he meant to say something like type: ffmpeg -i filename.vob -o .mp4>.

Continuing, Paul said that .mp4 is a good format for the final product, but it’s not the best if you want to do more editing — special effects, cuts, fades, dissolves etc.

These programs are free, Paul noted. Glenn added that the program Gimp is a free editing program for photos, and an alternative to Photo Shop. But Paul said it doesn’t do everything Photo Shop does and is not a replacement for it, but it still very useful.

The back of a modern TV has many inputs, among which is a USB port. If you plug in a USB flash drive containing videos, music or pictures, you can play those thru the TV. On some TVs you can play .mp4 videos. And if you name the videos for their content — holidayinspain.mp4 or wedding1996.mp4 — navigating the files is much easier. The order in which the videos are played depends on how the TV is programmed. Often it will be in alphabetical order. So you can rename your files to start with a_, b_, c_ or 1_, 2_, 3_ etc., in the order you want them to play.

Glenn said he was helping a friend put his videos on a 64 gig flash drive and found his TV wouldn’t play it. Eventually, they had to use 8 gig drives before the TV could play them. Check the specs of the TV before you make a commitment to using a particular size drive, he said. In this case the flash drives were to be sent to family members over seas.

Paul said it’s true of older equipment that larger drives can be a problem. It’s not that the engineers couldn’t anticipate that larger drives would eventually become available, but that the standards for accessing the larger drives weren’t agreed to until much later, when they went into production.

Paul talked about smart TVs that can be connected to the internet, You can store your videos on the web using Youtube, for instance, or your own website. You can then use a web browser, of course, or the Youtube app to play them. But many current TVs come with a Youtube app or Roku that can play the videos. And then there are plugin devices like Chromecast and Apple TV that you can also use.
<The Chromecast app is here>

Moving on, Paul said Google Drive is available on Android devices & iPhones. Google gives you 15gigs of storage for your videos <or other data>. Once you have uploaded some content, you can click on the folder containing the videos and share the link with anyone by typing their email address. That person can then view or download the video. Google Drive is a good way of distributing content. To be able to download; one needs a Google account, which is free. The guys have used Google Drive to great advantage over the years.

Glenn said he use both Gmail & Yahoo for email. His Yahoo account is for those casual things that won’t compromise privacy like signing up somewhere to get a discount coupon. Paul said he dislikes Yahoo but if you’re going to use it, get the mobile app as it does a somewhat better job. The app will also work for users of SBC Global, which uses Yahoo. Glenn mentioned that Gmail also has an app for its service.
<Yahoo app is here. This might be the one for iPhone>

Paul said that on the iPhone and probably on the Android, “when you create and log in to your Yahoo account with the settings under email, you can add more than one account”. Then “when you synchronize it, there is a bunch of little slider switches” that set exactly what you want to synch — like the calendar and contacts. But if you import contacts and you already have contacts on the iPhone, you can end up with 2 records for the same person and there is no easy way to remove them. Turning off the synchronization won’t make the duplicates go away.

Something similar happens on the iPhone when you use the Facebook app. But in this case, if you have synch turned on, it can drag in a bunch of other stuff from Facebook on to the iPhone.

Glenn talked about a problem he has while using his iPhone, iPad and Mac Mini. When he logs out of Facebook and later clicks an link in an email notification that says, for example, “David sent you something about their anniversary party last night”, he is taken to Facebook and automatically logged in there. He asked Paul how to stop that. Paul said, “the Facebook app requires a login. When you log out of the Facebook app, you haven’t been logged out of the account that’s been set up for Facebook”…”The reason for that is it logs you in without actually being able to show you the Facebook content. The only purpose behind it is to deliver notifications synchronize contacts”.

Paul added, “there is one single useful feature about creating a Facebook account login on your iPhone and that is if you synchronize calendars, all those events that come up that are a myriad of events all going around here in Nevada County”…”if you synchronize a calendar, they come up with a colored event in your iPhone calendar”. Unlike synching contacts, if you turn off the synching, the events will go away, you have an actual Ical link. <You can subscribe to other Ical calendars and the events will blend in with the calendar on your phone, and disappear when you unsubscribe, as I understand it.>

Glenn had the problem of multiple contacts showing up when he got an iPad some time ago and Apple told him they didn’t have a solution. But it was suggested that he export the contact list from the iPad and then import it to Google Contacts, because Google has a tool to eliminate duplicate entries or to merge entries that were only similar. He found that very useful.

Glenn said that some time ago, on another show, Mikail talked about a $30 tool to coordinate things without having to use the cloud for synching.
<That was at the end of the 9-12-18 show. The program is called Power Photos from Fat Cat Software>

Paul & Glenn both have upgraded their Apple device to IOS 12.1. And Paul mentioned on a previous show that the new Facetime made it tricky to flip the camera. “You had to hit 2 or 3 different things and you couldn’t see the camera, so a slider would come up on the screen”…”instead of showing what’s in front of the iPhone I want to show what’s behind the iPhone. You had to go thru several hoop to do that”. That was one of the things fixed in the latest version 12.1.1, you just tap on the screen to flip the camera.

Paul had a tip for iPhone users who have trouble positioning the cursor in the text they are editing. Hold your finger down on the spacebar and you will get what looks like a mouse pad that you can then use to move the cursor.

Glenn reminded listeners that they can call in with questions or comments at 530-265-9555.

Some time ago Paul suggested the Clean Sweep app for the Android to purge unnecessary files. It’s a widely used app from China, but it has a problem. It’s not a security issue. “It would hook into the system and artificially grab credit for your download of other apps that didn’t belong to it”, Paul said. Developers get a kickback from Google if their apps are installed and the makers of Cleansweep were raking in the money, instead. Google hasn’t removed the app or disabled it on all user devices (a killbit). Paul suggested that users delete the app on their devices. He didn’t have suggestion for a replacement. <CM Security Master has a cleaning function and there’s also CleanMaster.>
<Other apps involved in a similar scam are listed in this article: Android Ad Scam Hijacks Phones; Drains Data, Battery>

Glenn read the disclaimer:
The views and opinions expressed on KVMR are those of the speaker only and not necessarily those of KVMR management, staff or underwriters.

Brian called about a problem with his printer. He had called about it some time ago and was told how to make it the default printer. He wanted to be reminded how to do that because the default got changed. Brian said others use the computer and Glenn thought that the other person selected a different printer and the default automatically changed. Paul said the setting can be reached by clicking the Start button (lower left) -> Control Panel -> Devices and Printers and look at the list of printers. The one that’s the default will have a check mark. If you need to change it, right-click on the one you want and choose it as the default.

WordPress has gone to version 5. It now uses a different editor called Gutenberg. Paul doesn’t like it but “not all hope is lost”. He’ll talk more about it on the next show.

Glenn has a friend who got the latest iPad (6th generation) and it will only communicate using iMessage. It won’t use the phone number or email to communicate with non-Apple products. Paul said, “it will only be able to receive text messages that come thru the other device. So something has to receive the text message and it would be another device like the iPhone. So the text comes into the iPhone. That iPhone, under settings, has to be configured in such a way that it shares its messaging with the iPad. So when the iPad sees the text message it’s not because the iPad got a text message, it’s because the iPhone got it and shared it with the iPad.” Paul thought the setting on the iPhone is under Settings -> Messages or iMessage. “It should know about the iPad as long as the iPad is signed in to the same iCloud account. And that way the phone has to be on and the text message and even voice calls will pop up on the iPad.” Glenn looked at his phone and found the correct path to the setting: Settings -> Messages -> Text Message Forwarding.

Paul said that when you get a new device, rename it in a sensible way. “If you migrate all your settings from the iPhone 5 to your iPhone 6 and you called your iPhone 5 “iPhone 5″, that’s its name when it when it goes over to iPhone 6. So watch out for that one, that will bite you”. When you get a new device, give it a new unique name, Glenn said.

For a couple of months, the audio of today’s show is here. Recent shows are here.

The intro and outro music was by Pentatonix.

Both Paul and Glenn were in the studio today.

Paul mentioned that archive.kvmr.org has the audio from recent KVMR shows and that one can listen to a live stream of the shows by going to kvmr.org click on Listen Live.

Forgetting that there was a Community Calendar to present, Paul continued to explain that over the air digital broadcasting <not over internet, but similar to digital TV> has a sub-carrier to carry information such as station ID, weather info, amber alerts, etc.

Paul said he’s had experience as a radio amateur in his teen years when enthusiasts would often build their own radios transmitters. That’s not done much anymore as there are many inexpensive off the shelf transmitters. One lowest cost 2-meter transmitter is from a Chinese company called Baofeng with a digital display and keypad.

The test for a basic level 3 amateur license is no longer about constructing a transmitter, but more about what frequencies you can transmit on, how antennas work, what to do about interference or an emergency, etc.

Paul said he’s thinking about getting back into amateur radio by getting a license, He’s already found a radio for $22 <he gave no details>. Generally, no license is required for listening to radio broadcasts, he added.

Paul bought a Chinese USB device called an SDR, software defined radio. You can plug it into a PC, Linux or Mac computer with one end, and plug an antenna into its other end. The SDR takes the analog radio signal that comes in over the antenna, converts it to digital and then sends it to the computer. It’s the computer that decides what to with it. At this point, Glenn insisted on doing the Community Calendar, which took a few minutes.

After the Community Calendar, Paul announced that Sierra Roots is opening up a cold weather shelter this Sunday and Monday at 4pm at the veteran’s building located at 415 North Pine Street Nevada City.

Paul continued talking about SDR, software defined radio. He said he was aware of 2 SDRs — google either GWRX or Cubic SDR. He thought GWRX can work on PC, Linux and the Mac computers. The documentation that comes with it will get you started.

For radio, the antenna is cheapest part and the weak link, he said. It’s worth the trouble and attention you give it. For shortwave listening it’s simply a spool of wire strung out in such a way so as not to lose current down to ground. This is done by insulating the ends at the point of suspension. It’s not necessarily true that the longer the wire the better. The direction the wire faces and how it’s connected is more important.

GWRX will show you a spectrum of what’s being transmitted, on your screen. You can see all sorts of weird stuff depicted by bumps along the spectrum. He found that 121.5 FM is a frequency used by a local airport.

Paul clarified that no license is required to use an SDR because it’s incapable of transmitting. It’s only a receiver. You “hack and freak and do anything and tune anywhere” with an SDR.

Paul tried to receive the station WWV, which provides precise time signals. It’s the oldest continuously transmitting radio station in the US.

Call letters for radio stations West of St Louis generally start with a ‘K’ (KVMR) and those East with a ‘W’. It got started in the East, around Washington in the 1920s. It’s now in Colorado but retained the ‘W’. Funding for WWV is being threatened in part due to new technology — computers & mobile devices get their time synched over the internet.

Glenn mentioned that he bought a refurbished iPhone 8 (a late 2017 model) with 64 gigs of memory. He found that it’s exactly the same size as his iPhone 6S and fits into the Otter Box that he is currently using.

He said iPhone 8 from Oct 2017 and later models have Qi (chee) charging, meaning it can charge wirelessly. The charging is done inductively.
<More info about Qi here.
Qi was first mention during the 11-26-14 show>

Glenn bought a charging case for his iPhone 6, which does not use Qi charging. It’s from Patriot called a Fuel Ion and it’s $5 at Fry’s. It’s still on sale, he said. When the iPhone 6 is plugged into the case, the case itself can charge the phone. <At first I thought he meant it uses the Qi charger. But Paul pointed out, in a way I couldn’t follow, that it uses some concentric gold plated circles to do contact charging, it’s not inductive.>

When Glenn turned on his iPhone 8 and it got past the ‘language greeting’, it said “if you would like to change over from your previous iPhone to this iPhone, put the two of them next to each other.” Paul said you have to be using at lest IOS 11 to migrate one to the other. Glenn said it did an excellent job with the settings, alarms and the pre-entered wi-fi information. And it was quick. It didn’t migrate the apps. He had to use iTunes for that.

Paul said there’s some indication that Google is trying to change Android into a platform independent OS so its apps will work on more platforms.

Paul mentioned that SSDs (solid state drives) are replacing the spinning drive market. Their price keeps coming down and one day soon, if not already, the number of machines sold with SSDs will exceed those with mechanical drives. Glenn noted that they use less electricity. Paul said it’s typically 1.5 to 2 watts, judging from the one he bought. And they work much faster. If Paul has to repair someone’s computer, he’ll often replace a spinning drive with an SSD. Paul said he tends to stick with brand names for SSDs like Samsung, Sony or San Disk. <SSDs were mentioned on the 8-9-17 show.>

Glenn spoke more about the refurbished iPhone 8 he just bought. It comes with a 1-year warranty. And you can buy Apple Care for it for $130, which adds an additional year. But Glenn contacted customer service for his Citi Costco Credit Card to ask about, what he thought, a 1-year extension on the warranty. He found out that they now offer a 2-year extension. So he didn’t get the Apple Care. However, Paul pointed out that Apple Care covers more than his credit card would.

Glenn invited listeners to call 530-265-9555 with their questions and comments.

Ellen called. She had to get a new phone along with a new number, and ported her old number to Google Voice. Her phone now rings “when it comes in to the other number”, but when she answers it, the call is cut off. Glenn said that he also has Google Voice and he’ll have Paul call him to see if he has the same problem. He’ll report the results in the show notes.

Paul said there are a bunch of setting for Google Voice. Go to google.com/voice. One of the settings Paul likes requires the caller has to say their name. He thought she might have it turned on in her settings and it’s causing the problem. She can test it, but not by using her own phone — she should call her Google Voice number from an unrelated phone line and see what happens.

Scott called about the 121.5 airport frequency that Paul talked about. He said it is the emergency frequency. He thought that particular frequency might soon be decommissioned. The aircraft band goes from about 108 megahertz up to 135. The lower half, up to about 118, is generally for navigation. The rest is for voice. And it mostly uses AM, not FM.

Scott expressed his surprised that it’s taken so long for inductive charging to come to phones. His toothbrush uses it, and it’s 10 years old. Paul said the reason might because of the need to insure the rest of complicated phone circuitry isn’t adversely affected.

Glenn had been charging his iPhone 8 inductively during the show. He reported that it just now hit 100%. It took 53 minutes to go from 81% to 100% charged. The iPhone 6S, where he “added the inductive charge”, it went from 78% to 95% charged.

Paul said induction charging side steps the potential problems of using a large current of around 2 amps to charge a phone, which can shorten the lifetime of the battery and possibly damage the contacts.

Battery life can also take a hit if it’s much above room temperature — nearing 90 degrees F. Battery “age stars to degrade and the number of cycles available decreases with temperature over time.”

Paul said he’s been using Ubuntu Linux for many years. Others have espoused Mint Linux. He’s now found out that Mint is based on Unbuntu and uses the same upgrade path. It’s much more lightweight and uses the Cinnamon desktop. The Cinnamon desktop is also very lightweight and it’s “the most efficient distribution of Linux” Paul has seen for old machines with limited hardware. It should be a good replacement for Windows XP. It’s also available for 32bit machines. If you’re about to turn you computer over to the recycler, give Mint a try.

Paul mentioned an internet of things (IOT) alarm system for around $50-$60 from China. The Nest thermostat learns your behavior, Glenn added. There’s a potential to save energy and money as products get smarter.

For a couple of months, the audio of today’s show is here. Recent shows are here.

The intro and outro music was by Pentatonix.

Both Glenn and Paul were in the studio today.

Before the guys did the community calendar, Glenn mentioned that he finally updated his iPhone and iPad to IOS 12.

Paul talked a bit about top level domain names (.com .net .org .coop). Glenn wasn’t sure if .coop had a dash in it. Paul said the domain names are case insensitive — Kvmr.ORG is just as good as kvmr.org. Most punctuation marks, like the dash, cannot be included in the domain name.

Originally, there were just a few top level domain names: .com .net .org [.gov]. Now it’s been opened up and people can bid on the names they want to use such as .xxx .mobile .world .mob. <By ‘people’ I think he meant those who will later resell (register) the use of the domain names.> Go to Wikipedia and search for the words: top level domain naming.

.com was the first and most popular domain in use. At some point, maybe more than 10 years ago, there was a claim that every word in the Oxford and Webster’s dictionaries has been registered to use with .com (color.com elephant.com banana.com cheeseburger.com etc.) Eventually, many foreign words were also claimed.

Two letters is the least you can have (ab.com). The exceptions are the x.com, y.com and z.com. y.com is owned by Yahoo and x.com by Paypal. The maximum number of characters allowed went from 64 to something like 254 (Paul couldn’t remember exactly).

Paul went on to say that some people, though not so much now, would ‘park’ a domain name like harvard.com because it doesn’t cost much to register a particular name. The hope is that Harvard (harvard.edu) would pay to take over harvard.com to prevent abuse of its name. And then there’s the incidental collision of names like Apple using apple.com to the dismay of Apple records. That was not such a problem until Apple started selling Beatles music on iTunes. There was some litigation about that, which was eventually settled. <There’s more about top level domain names & registering for one in the notes for the 7-11-18 show>

Paul mentioned a Stephen Colbert show that talked about how televangelists can get away with soliciting funds in the name of religion to pay for things like private jets. Because religion is such a touchy subject in this country, the IRS doesn’t even try to crack down on them. The concepts Paul came away with are that freedom of speech doesn’t mean you have to tell the truth and you should never confuse opinions with facts

Glenn cited the disclaimer:
Our opinions are not necessarily those of our staff, our broadcasters, our underwriters or contributors to the station.

As Glenn mentioned at the beginning, he has upgraded his Apple devices to IOS 12 but noted that the current version is now 12.1. Paul said there is an improvement in Facetime in 12.1 that allows the user to talk to multiple people at once. The downside, Paul said, is that if you’re talking to someone and you want to flip the screen around, you have to do 3 things: touch the 3 little dots that pops the menu up, “go flip to turn it around the other way” which you don’t actually see happening and then “drag it back down again”.

Paul encountered a problem with his Mac. He was listening to music playing on his Mac using Airplay which was sending it over to his stereo. When Glenn called him, it showed up on the screen of the Mac. He then used his phone to answer the call, but the Mack stopped playing the music and Glenn’s voice came out of the speakers instead. Paul said he’ll have to look into why that happens.

Paul talked about the problem I’m having with logging into the Zen Tech website, which uses WordPress. The trouble is with the Google captcha that requires me to provide the correct answer to a graphical challenge — picking which of several images have a particular object like street signs or cars or store fronts. The idea is to prevent bots from logging in and creating mischief.

As far as we can determine, the web browsers I’ve tried are out of date and it’s getting increasingly difficult to get a newer browser that will run on an older operating system and still work with Google’s captcha system. <I’ll have to do some experimenting and hopefully find one that works.>

Next, Glenn talked about the Camp Fire, one of the biggest and most deadly fires California has ever had. He’s tried to find a website that has satellite pictures of the area but was unable to. Butte County has announced a service that will allow people to search for an address and get the status of the property.

Paul asked listeners to suggest authoritative sources that provide information about the fires. Glenn mentioned that buttecounty.net has some info, including a status map of the structures in the area of the Camp Fire. Paul thought that yubanet.com might also have some info.

Paul talked about google.org, which is a nonprofit side of Google that provides free service to people who want to use their mapping and search engine. In particular he found google.org/crisismap/us-wildfires. It’s overlaid with data that’s provided by fire services of various places around the country. He said you can zoom in on the maps provided there. Also check out google.org/crisismap, which is has a broader category of subjects including weather. And google.org talks about the work they do.

Glenn invited people to call in to 530-265-9555 with questions and comments.

Paul noted that whitehouse.com used to be a porn sight. Apparently, when the government website whitehouse.gov was created, no thought was given to reserve the name in other domains. Whitehouse.org is a political parody website.

Laurel called from Sacramento to say that looters and others with nefarious intent can use the fire mapping services to facilitate their crimes.

Paul said the US Postal Service lets you register with them to get advanced notice that a letter is coming to you. They take a photo of the outside of the letter and email it to you. The problem is that they can’t be sure that the person registering for the service is the one who actually lives at that address. Someone with criminal intent can use the service to tell if a credit card <or maybe a check> is on its way and intercept it. Someone looked into the method used to verify that the address belongs to the correct resident and found it severely lacking.

Robyn called. She says that she’s getting notifications on her Android LG phone that she’s getting low on space. She has a bunch of apps but uses only 3. She wanted to know how to tell for sure which apps she won’t need and can safely delete.
– Put your finger on the app [icon] that you want to delete and then start to drag it. The uninstall “target” will then appear and you finish by dragging to that target.
– You can use the free app called Clean Sweep to free up the scratch and temporary files that are taking up the memory space. Then it will ask you about old photos you haven’t looked at in a while. Then it will do the same with messages. It may try to get you to install other things you don’t need — ignore all of that. <There’s also CleanMaster>
– Paul said that apps generally don’t take up much space. The Facebook app is only about 300 Kbytes to 400 Kbytes. But it will bring in a lot of Facebook content and store it on the phone. If you delete the app, the data will be cleared out. You can then reinstall the app and start fresh.
– If you delete an app and then find you need it, you can usually reinstall it.
– Some apps come preinstalled by the phone maker and you’ll have to make a special effort to uninstall them. <Typically you’ll have to ‘root‘ the phone.>
– Go to Settings (the cogwheel) -> Storage and check how much memory is being used and how much is available. Also check the storage used by each app. Look for the applications you don’t use but take up a lot of space.
– Write down which apps you delete so if you discover you can’t do something you used to do, you’ll know which apps to reinstall. Usually it’s the Play Store that has the apps you’ve deleted, <though it’s possible to get them elsewhere>.
