The guys seemed to think there is not a 5th Wed this month and said so at the end of the show. Well, according to my calendar, the 29th is the 5th Wednesday.

Paul was in the studio by himself. Glenn joined in by phone.

The show opened with music by Weird Al. <See the above link>

Glenn got a battery backup case for his iPhone. It cost him less than $7 including shipping, from Ebay. The good deal was due to its color — yellow. The case contains a chargeable battery, which then charges the iPhone battery, according to the way Glenn explained it.

Paul then told us about the battery-saving strategies that cell phones use when communicating with the towers. Where the cell signal is weak the phone has to put out more power to stay connected, thus draining the battery faster. Inversely, a stronger signal from the tower means the phone uses less power.

Glenn said, in his experience, he's found that to be true and gave tips to conserve the battery.
– Turn off Bluetooth.
– Turn wi-fi off.
– Doing a lot of uploading, like videos, will flatten the battery sooner.
<Related: Making your lithium battery last longer:>

Paul said that a large part of the operation system in a mobile device is devoted to conserve power.
– It doesn't continuously listen for a signal.
– It doesn't constantly send a signal at full power to reach a cell tower. – – It uses a complex algorithm, pinging the towers with short signal bursts. And then it uses "reciprocal backoff": it extends the time between pings until they come about a minute apart.

Paul said if you place your cell phone near an amplifier or even a PC speaker, you can tell from the noise you hear if a call or a text is about to come in.

Paul thought Ebay does a great service by recycling (reusing) used equipment and parts. For instance, parts (like keytops from keyboards) are sometimes stripped out of obsolete equipment and resold instead of ending up in the dump. He also mentioned Freecycle — a website to find recycled parts,

The guys then talked about the Maker Fair. Glenn said the idea stared with a dad helping his daughter with projects, and that led to the magazine called Make and, eventually, to get-togethers (fairs). He recounted how he and Paul got drawn into a local group called The Courious Forge. Now there are fairs in many parts of the country, like the well known The Crucible in Oakland. The next big regional fair will be in San Mateo on the weekend of May 18th & 19th. Links to Maker Faire & The Curious Forge are above.

When men talk while doing other things (multi-tasking), their voices tend to become monotone. Paul said that's not noticeable when it comes to women. Supposedly, men have a serial brain, women a parallel brain.

Up until a few years ago, CPU's did things one at a time. They would rapidly switch between tasks to do multiple things: displaying your email, running Microsoft Word, checking for keyboard activity, etc. These days, Paul said, he would not buy a computer that didn't have at least 2 brains that are multi-threaded: where the operating system assigns different tasks to each of the brains. Some of the latest processors are "duo core duo chip" (essentially 4 chips). Not all applications can make use of this feature. The Adobe Creative Suite version 3 (approx.) or greater does make use of this facility.

Ely called about creating a website and wanted recommendations for a web host (the place where webpages reside).
– A good web host should be cheap, no reason to pay a lot of money, maybe $50 or $60 per year. The guys won't endorse a particular host except for 1and1.com. Also check out lunarpages.com.
– If you see a website you like and want to know who the host is, you can go to netcraft.com. Submit the web address of the website and it will tell you the software it uses as well as the host.
– Many hosting sites offer a free trial period.

Ely is learning to use HTML and Paul didn't want to discourage Ely, but there are newer & better tools for creating webpages. These tools may create HTML as you use them, but you'll not have to deal with HTML directly.
– Try WordPress.com. You can create a webpage there for free.

Glenn asked about HTML5. Paul said that's the latest iteration of HTML. It has the ability to render video "and stuff".

Ely creates games that use HTML5. Paul said in that case you may indeed have to deal with the HTML code itself. It may be possible to insert HTML directly into WordPress while creating a webpage, but he wasn't sure. He also suggest that Ely explore AJAX: a mix of HTML and Javascript, which is sometimes used for gaming.

Thinking Paul said Java, Glenn cautioned us that it's had some vulnerability lately. Paul said Javascript is different from Java and that it's a good idea to uninstall the Java Virtual Machine, but it has nothing to do with Javascript.
<Talked about in the 1-23-13 show. See the notes for related articles,>

Paul then talked about a version of Linux called Ubuntu. This operating system will sometimes run on older equipment that would otherwise be trashed, giving it a second life. Ubuntu is usually run from a bootable CD, so the old computer will have to have a working CD drive <and be able to boot from it>.

The current version of Ubuntu is 13 but it seems to be somewhat flawed so Paul said he's sticking to version 12.04, which has long-term support. It's "generationally frozen", meaning it won't change much over 4 or 5 years.

The Macbook Air doesn't have a CD drive, making it problematic to install software from CDs. The latest Macbook Air doesn't even have an Ethernet connection, only wi-fi. And wi-fi is not particularly fast and it's prone to interruptions that can interfere with an installation.
– You can stick the CD into a PC and share it on a network <where the Mac can see it>. But if it's a Mac-formatted CD, you "can't sensibly share it from a PC".
– Create an ISO image. <See the above link> Make the name of the file end in .iso and send the file to the Mac. The Mac can understand that file type and can mount it on the desktop. It's as if you had shoved a CD into a drive. The Mac can then use the file as if it were the original CD.
– This trick won't work with movies because of the copy protection scheme they use.
– The CD must not have any defects. Paul said that it should be perfectly ok to wash the CD using detergent and then carefully dry it.

Steve called with a question about his Netgear wireless router. He said it would work for a while and then stop receiving from the internet. It's about 6 years old and is connected to a cable modem.
– They are cheap enough, just replace it…about $20. But you should determine the router is the actual problem, not something else.
– Verify that your cable service is not the problem. Steve did, by plugging the cable modem directly into the computer: problem went away.
– Steve said the problem goes away when the router is connected to the computer by cable. It only happens when he uses the wireless portion of the router.
– As more of your neighbors get wireless, interference can become a problem. Check your list of detected wireless networks. If there are a lot of them, interference may indeed be the cause.
– If you suspect interference, run the software called Netstumbler to give you info about what channels the neighboring transmitters are using. You may be using the same channel as one of your neighbors.
– Cordless phones use similar frequencies. Keep them far away. In fact, unplug them while you're diagnosing the problem.
– Older phones & routers used 2.4gHz and tended to interfere more than modern equipment. Both types of devices tend to now use 5.8gHz but are designed better to avoid interference.

There is a method that Paul is not recommending and that he's never tried, to avoid interference. When you rest the unit <router, I assume> pick the channel group that's used in Europe. That can make it easier to find a channel to use that's different from your neighbors. However the authorities may detect your use of those channels and cause you grief. So remember, you didn't hear it on Zentech.

Scott called. He got a CD from KVMR when he became a member but couldn't get it to play on his Macbook Pro. When he puts it in the drive he'd get the message "you inserted a blank CD". The CD works fine in his (physical) CD player.
– The music may have been burned as data files <.mp3> rather than audio format <Red Book Audio>
– Bring the disk back to KVMR for an exchange. But Scott said it's not that important, he was just curious about the cause of the problem.
– CD drives in computer suffer badly even if they're not used much, even in as little as 3 years.
– You can try a CD cleaning disk.
– As a last resort, try blowing the drive out with air. But that may dislodge dust and put it someplace else, causing more problems.

You too can become a KVMR member.

Both Glenn and Paul were in the studio.

Glenn thanked all those who became members of KVMR. To become a member, please go to KVMR.

The guys briefly talked about the algorithm for determining Easter.
<Refer to the 3/24/08 show>

Glenn said he recently got a used iPhone 4S. He got a pretty good deal but there were some issues. Paul said there's quite a market for used, unlocked or refurbished 3GS & 4GS iPhones on Amazon.

Glenn has been looking for one for a few months. He previously bought a Sprint iPhone 4S while mistakenly thinking he could get it to work on T-Mobile but found out that, until it's unlocked, he couldn't use a different SIM card <which lets him change carriers>. Even then, that option may only be available to international travelers, not to those within the USA.

Pure Talk (Glenn's carrier) doesn't require a phone to be unlocked because they use the AT&T network, so an iPhone originally on contract with AT&T should be good to go. Nevertheless he had problems…
– He brought the person he was buying the phone from to an AT&T store to verify the phone was indeed hers.
– After verifying, he asked that the phone be unlocked and was told that they couldn't do it because she was still under contract. And they couldn't unlock it later (after Glenn bought it and the contract was up) because the phone would not be hers by then. He didn't argue further because he didn't really need it unlocked to use it on Pure Talk.
– He then told her he'd like to go over to Apple and have them do a diagnostic to check if anything has been replaced, if there's water damage, etc. Apple found that it did have water damage. Paul noted that some other cell phones have a dye spot under the battery that changes color after contact with water.
– Because of the water damage, he got her to come down on the price and they settled on $280.
– After the transaction, he found out she had a warranty under Apple CarePlus. Glenn, "…had this not been under any kind of extended care, they <Apple> would have exchanged it for $150". With Apple Care there's only a $50 deductible so he's not worried as he can get the phone replaced before the Apple Care runs out.
– Paul mentioned there are other warranties available (not from Apple) that cover specific things like the glass breaking. Glenn said that some cell carriers also offer limited insurance for about $7 or $8 per month plus deductible.

Paul has had phones come off his belt clip and fall to the ground. So, on Ebay, he found a latchable belt halter, which can't come off without the loop being ripped. He's had success with that as well as a silicon rubber case (about $4 form Hong Kong) that has thick corners to cushion a fall.

Glenn mentioned a phone case called an Otter Box. He got one for his iPhone 3GS on Ebay for less than $30. He said they make cases with varying degrees of protection going up to waterproof.

Paul talked about the iPad being used as a "control surface". Instead of a traditional computer interface controlling a mixer or lighting on a stage or an irrigation system, for example, a control surface (iPad) tells the computer what to do, which in turn controls the equipment. This gives a sound engineer, for example, the ability to change the sound while standing in different places in a theater.

Paul went on to say that iPads are also being used as cash registers. Some of the software is free, but if you want it to print receipts, keep tax records, integrate with tax software, etc., you'll have to pay a subscription fee. This type of software often stores data on the internet and if you lose the iPad, the data is still safe.

Glenn said he was in a restaurant that used an iPad to process payments using Square. His complaint was that he couldn't see what items were being charged, unless the iPad was deliberately turned in his direction.

Paul said that even though people like the MacBook Air, its thinness makes it vulnerable to damage. Glenn noted that the ASUS 12" netbook, which they both own, is surprisingly sturdy.

One of Paul's peeves is that laptops are still being made with power sockets that fail. Apple has an improved connector called magsafe that allows the plug to come out easily, reducing the force put on the interior of the computer. He thought that if other laptops would at least use a right-angled power connector, it would be an improvement. Paul said he's never secured the VGA computer-to-monitor connector with its screws, preferring it come out accidentally than rip the screws or bend the pins.

Glenn said he has an iPad app to give him information about the Moon: rise/set times, phase, etc. The app is simply called Moon. Paul loves the astronomy app called Star Walk from the European Space Agency (ESA). It keeps track of ephemera: things that come & go in the sky like comets, planets as well as the moon. And it has cool music. It uses some of the sensors in the iPhone, so at least an iPhone 3G is required.
<I think this may be the Star Walk app>

Paul said you should have nothing older than an iPhone 3G because current apps won't load.
– The 3G can run the latest operating system: 613 <maybe 6.1.3>.
– The 3G won't take panoramic photos.
– The 3G won't run Siri. Siri won't run on a iPhone 4 either, you need a 4S.
– There is a Google app that's alternative to Siri. <He didn't name the app>. The app is for both the Android and iPhone. Glenn said it understands his spoken words better than Siri. But it doesn't integrate with iPhone's operating system: you can't set your calendar, for instance.

Paul offered a tip for those who don't have a data plan and can't surf the web. If you want to know what the weather is, you can text (txt) the word 'weather' to Google. This works for 'movies' and many other things. It will tell you what's in your vicinity. If you text 'location' followed by your zip code, Google will tailor the results to your location. It will associate your phone number with the zip code so subsequent queries will also be tailored to your location. Text the word 'help' to learn more.

Paul talked briefly about how a service can tell where you are. DSL connections in this area are broadly identified as coming from Sacramento and Comcast from Yuba City or Chico. And people <concerned about privacy> may be interested to know that wi-fi connections "do know how to figure out where they are". Paul's not sure how they do that, he speculated it may have something to do with the information Google collected when it sent out vehicles for its Street View project.

Glenn said he had thought that the Google cars (used for the Street View project) were driverless when in fact they had drivers. But the drivers were there only for emergencies — so the cars were essentially autonomous. Googles software for driverless cars is being considered for long haul trucking and costs about $150,000. Insurance liability and legislation, as usual, need to catch up to the technology.

Robert called only to say he loves the show.

Michael called. He has a Nook (an ereader from Barns & Nobel) that he dropped into water. He had previously done the same with a cell phone. He tried putting them into a container of rice to speed up the drying. The cell phone recovered but not the Nook. He asked if anyone repairs them.
– Yes, there are places in Sacramento.
– There is a place in Rocklin near the intersection of Rocklin Blvd & Sierra College Blvd (near the college). Paul did a search and found Yakety Yak.
– If the circuit board is damaged, the cost of repair will be pretty high.

Michael said he didn't use it as an ereader but only as a tablet and wondered if some other cheap tablet would suit him.
– Glenn seemed to think so. He's seen tablets down around $70. Check Buy.com <now Rakuten>, overstock.com, Ebay or Amazon for bargains.
– If you were interested in ebooks, the Android, iPhone, iPad <and the PC> have the Kindle ebook software, which you can use to buy ebooks from Amazon. There's similar Nook software too. Just make sure the device you get has a display that's adequate for reading.

Michael asked what differences to expect between the cheapest tablets and those just a little over $100.
– Screen size might be bigger as you go up in price.
– They may have capacitive touch vs. resistive touch, which is not as responsive.
– Fry's sale for today & tomorrow offers a 7" tablet for $69.
– Do some hand-on shopping before buying. Especially to compare the 2 different types of touch screens.

Michael has had trouble listening to KVMR over the internet. Paul thought using an app to listen to radio stations might be more reliable than clicking on a webpage link. He couldn't remember the app he was about to recommend. He did mention that KVMR has many (mostly non-music) shows available online.

Paul talked about hacking (in the traditional sense) Android devices. Some Android devices allow root access when they are hacked in a procedure called rooting. This will allow you to access features the manufacturer didn't intend you to have: like installing the latest operating system. Not all Android devices will allow this. To find out more, google the words: root android followed by the name of your device.

Glenn previously used Evasi0n to jailbreak his iPhone 3GS but found it doesn't work with his 4S: only works on iPhone 4 and earlier. It doesn't work with iOS version 6.1.3 and Apple changed version 6.1.2 to foil Evasi0n. Expect the cat & mouse game to continue with newer updates.

Scott called. He has MacBook Pro with a faulty Nvidia card (apparently a known defect). He got it to work by turning down the screen resolution but wondered if he's just postponing the inevitable and should start looking for another computer.
– There have been 2 rounds of recalls for this problem and now it's been long enough that there are units that fall outside of the recall period.
– The symptoms are so sporadic it's advised to take pictures of the malfunction. Then go to the Apple store and (no promises) they'll "care of it" for $150,
– It's a problem that goes back several models. The video chip would become dislodged, possibly from thermal stress.
– Rumor says you can take the back off and insert some foam, so when the case is closed the foam will push the chip back into contact with the circuit board. Make sure the foam is heat resistant so it doesn't melt or burn.
– During manufacture, special soldering equipment is used, because the pins are so small and close together. It's not a project for the average hardware hacker to attempt.
– Try an external monitor.
– Try a USB cooling pad underneath the computer.
– Later Macs have an onboard video chip that's part of the Intel CPU, as well as the 'external' video chip, which uses more power. The Mac software arbitrates the usage as the demand for graphic processing changes.
– Google the words: switch gpu. One of the results is a reference to TomsHardware that talks about a piece of software that lets you force it to use one graphics chip or the other. In this case, tell it not to use the Nvidia chip.

Paul offered some general tips when your hardware goes wrong:
– Check to see if you have a warranty. Refurbished stuff will sometimes have a limited warranty.
– Check if you have an extended warranty that comes thru using credit card. That can double the warranty for up to an additional year.
– See if you have additional insurance like Apple Care.
– Check for recalls. Google the words: recall with the make & model of your unit.
– It may be a well-known defect that has a well-known solution. Like the above suggestion to use a cooling pad.
– Some problems are age related. Google the words: bad caps. There is a group of machine made for about 10 years, ending a few years ago, that have bad capacitors: the caps dried up over time.

Glenn and Mikail Graham were in the studio.

There will NOT be a Zentech show on Apr 10 due to the membership drive.

For his cell phone service, Glenn switched from T-Mobile to Pure TalkUSA, which uses the AT&T network. He pays $45/mo and is happy with it. The plan he's on offers 600 megabytes/mo of data thru the cellular network. He tends to use the wi-fi option that comes with it so as not to use up his alloted data limit. The plan had unlimited talk and text.

Mikail said T-Mobile will be carrying a special version of the iPhone5 that Verizon & AT&T do not have. Its new technology allows it to work on T-Mobile using a broader range of frequencies. Next versions of the AT&T iPhone5 will also have the newer chip.

Mikail said T-Mobile is "not doing subsidised phones anymore". "You go and buy your 16gig iPhone5 for $579 thru them, as oppossed to $649, which is what you'd pay if you bought it at the Apple store…you put down $100 and you pay $20/mo for 2 years, but it's all up front, so your price of your actual monthly deal comes down. Whereas, with AT&T and Verizon you get a phone for $200…but…if you don't get a new phone in 2 years, they're still making money off the subsidy that you're paying for in your contract because your contract cost you more and you get less"
<I haven't had a chance to read these articles about T-Mobile's new plan. Hopefully, they'll be clearer than what was said on today's show…
T-Mobile to offer unlimited, no-contract plans — and the iPhone
T-Mobile's New Contractless Data Plan Debunked (FAQ)
The Fine Print on T-Mobile’s New No-Contract Cellphone Plans>

Glenn mentioned, again, his contract troubles with T-Mobile — he was put on a 2 year contract without being told. After canceling his contract they still want $277 that he's going to dispute.

Mikail went over some of the cell phone contracts, I think he was talking about the phone only.
– For T-Mobile it's $100 no contract
– For AT&T it's $200, $300 or $400 with a 2 year contract depending on the <memory> size of the iPhone. Verizon & Sprint are similar.

For the data plans:
– T-Mobile 500meg or 2.5gig and unlimited text & voice starts at $50/mo.
– AT&T 300meg/mo for $20/mo and that's on top of your voice plan.
– Verizon $40/mo for 300meg/mo.

Mikial on the overall costs..
– T-Mobile is $1780 (500meg/mo & voice on a 2 year contract).
– AT&T $1640 (300meg/mo & pay-as-you-go texting for 2 years).
– Verizon $2120 (300meg/mo for 2 year contract).
– Sprint $2120 (450 min & unlimited data for 2 years).
– Pure TalkUSA looks like a great deal. Glenn said it's $43.95/mo $1078.80 for 2 years.

Mikail noted that, unlike in Europe, cell phone users here have to pay to both receive and initiate a call and he doesn't understand why people are so accepting.

Glenn said Pure TalkUSA gives you unlimited talk & text (txt), 600meg data and 600 multimedia messages (MMS).
Mikail said they've got affordable plans starting at $10/mo. 130 minutes with rollover, Glenn added.
Additionally, you don't have to unlock you phone if you're already with AT&T.

Lorraine called to say AT&T and Verizon are notoriously horrible politically, especially for women. In Hawaii she used Credo Mobile "1% of everything goes to the progressive cause of my choice" and the customer service is great, she said. She has a minimal plan for $40/mo. Her son's plan "has everything" for $90/mo.

The disclaimer:
The views and opinions expressed on this show are those of the speakers only and not necessarily those of KVMR, its board, management, staff or contributors.

Jerome called about a plan he said is cheaper than those mentioned so far but he doesn't know if it supports the iPhone. He has a Verizon pre-paid data plan at $20 or $25/mo that gives him 1gig of data. In addition, he has Line 2, an app that gives him a phone line, voice over ip <VOIP>. Line 2 can use wi-fi to avoid cell phone charges. The Line 2 service cost him $10/mo. Mikial noted that audio quality can sometimes drop with VOIP services. Jerome was surpised to find that Line 2 works while driving down the freeway (in this case it uses the Verizon cellular 1gig data plan). Essentially, he gets unlimited voice & text when he can get a wi-fi connection (he doesn't have to use any of the 1gig of data in this case) and uses Verizon cellular when there's no wi-fi. There is no contract for either Verizon or Line 2 — he pays month-to-month.

 Shiloh called, She's been using Verizon for a very long time and she was grandfathered-in at $14.95/mo. She gets 3500 night/weekend minutes and 10 daytime minutes. From what I can decipher, she got another phone, which she thinks is crappy, and signed a service contract. She doesn't do texting but would like to have voice mail. She tried a TracFone but reception was poor. She'd like to get something with a wide screen and a decent camera
– Mikail said you can get a free iPhone 4 with a contract from Verizon or AT&T. (But she's already signed a contract)
– Glenn suggested she buy a separate camera. You can get a really nice one for about $100. If you don't have a data plan, you can't do anything with a phone camera except transfer the pictures to your computer <there's no advantage over a regular camera>. From there, of course, you can upload them to the web.
– For voice mail try Google Voice. That's what Glenn uses, He enters a special code he got from Google Voice into his phone, which deactivates the Pure TalkUSA voice mail and allows Google Voice to receive the message. Mikail uses YouMail (as well as Google Voice), it has greetings that are personalized to the particular caller. Both Google Voice and YouMail have free versions.
– With either of these services, you can access your messages from your computer, store them or have them converted to text.
– You can get an iPod Touch. It has a camera and all of the smartphone features. You won't have a cell phone but will be able to use VOIP over wi-fi — the way Jerome just got thru telling us. Of course you'll need wi-fi in your house if you want to use it at home.

John of Spiral Internet called to update us on the fiber cable being laid in the Nevada County area. It's meant to connect 3 schools and a library — won't go to houses. Spiral Internet intends to "extend from that" and bring "fiber to the home" and possibly provide better backhaul to the local wireless providers (Smarter Broadband & Digital Path). John said it will take a while — 2 years for phase 1 and 7 years for further deployment. Those who are interested can contribute to a survey at spiralinternet.com/survey.

Doug called. Like Shiloh, he seldom uses the cell phone. He used to have a Verizon plan, then went to TracPhone but had problems. He was initially told it can use the Verizon network but later found out it can only use the AT&T network. He gets poor reception with AT&T. He heard that Walmart has a service called StraightTalk that works thru Verizon and asked if that's correct. He also wondered about the Net10 service.
– Net10 is another Walmart product.
– Glenn didn't know anything about StraightTalk but said to give them a call.

Doug also wondered if some cell phones are better at receiving weak signals.
– They're all pretty good these days
– Check with Consumer Reports for comparisons. If you don't subscribe to them, a local library may have access.

James called. He read a news item about T-Mobile offering a new plan. <Apparently he didn't listen to the first part of this broadcast>
– Mikail reiterated: "You're not locked into a contract when you do that. When the phone's done <paid for> you own it and you're not paying any extra premium a month for that subsidy, which is what's happening with AT&T or Verizon". You get an iPhone or Galaxy 4 for $200 and think that's cool, much better than $600 at full price, but you pay for it in your contract and "that doesn't go away at the end of those 2 years".
– Again, check out Pure TalkUSA.

Ken called. He likes Apple and would like to get an iPhone. He wanted to know what carriers he could use that take a SIM card.
– Your options (not exclusively) Sprint, Verizon, AT&T, T-Mobile and Pure TalkUSA. You can use these without having to jailbreak or unlock the phone.
– Glenn thought some iPhones don't take a SIM card. Mikail said they all do. <They 'take' SIM cards but still have limitations>
– Glenn said he previously bought an iPhone 4S that had been used with the Sprint system and found it was impossible to make it work on other systems.
– Mikial: You can use a Verizon iPhone with GSM on the AT&T network. You have to get it off the Verizon contract. This is true for the iPhone 5, not the iPhone 4S.
– Glenn added that those who travel abroad should look for a GSM phone. It's what's used in most of the world. Mikail thinks CDMA is being supplanted by GSM. He said the new Qualcom multi-band chips can accommodate almost anything and you should start seeing them on more new phones.

Mikail played with Siri, asking it "what's the best cell phone on the market". Siri replied "Wait, there are other phones", He then went on to demonstrate other voices that Siri can use — British, Australian and French (others are available). He said when you first start to use Siri the voice sounds odd, but it gets better as it learns about your environment and adapts to it. To change the voice go to settings -> general -> siri and choose your language.

Glenn thanked the KVMR members. To become a member, go to KVMR.

James called to complain about cell phone quality. He gets annoyed when people call in to radio talk shows and their cell phones betray them.
– HD Voice is on the horizon. More cell phones are starting use it. The newer Samsung & iPhones are starting to support it, but it may be another year before it becomes ubiquitous. It's currently available only thru the T-Mobile carrier network, others should follow.

Megan called asking about any good places to donate cell phones.
– Check places that sell phones for a donation bin.
– Check with DVSAC. <I think that's what was said. It's a domestic violence organization>

In closing, Mikail spoke about Mailplane, an email app. <Looks like it's only for the Mac>
– It works with IMAP. <a mail protocol> It's "like having a browser separate from your browser"
– It's primarily for Gmail. All of it's features are there, like "undo send" to call back unintended emails.
– It supports other Google services like calendar.
– Mikail thinks it's fabulous.
– It's $24:95

The guys talked about the recent switch to Daylight Savings Time. Paul noted that those running older versions of Unix, which hasn't been updated recently, may find that it uses the wrong date to do the time change. There is a database of world timezones called TZdata that keeps track of the latest changes to timezone laws. <Keep your software updated>

Speaking of updates, Paul said nothing older than Windows XP should be on the internet. Anything older is not supported with patches and might be ignored by some anti-virus programs, too.

KVMR has a new low-power translator (boosts the signal for a local area) in Woodland at 104.7 FM. Listeners were asked to try it and report their results to David Barnette via email to: engineer at kvmr dot org

Glenn said AT&T internet service is available along Highway 49 North of the South Yuba river. He's not sure if it's U-verse or DSL. To find out if it's available to you, go to att.com -> shop -> internet -> check for new service. He said it is available at the intersection of Pleasant Valley Road & Hwy 49.

Paul lamented that Firefox updates its browser so often. When he upgrades, the settings sometimes get changed from those he prefers.

Glenn said KVMR's office computer currently has a virus on it, possibly due to someone carelessly clicking in a popup window. He said the virus would sometime pop up a box saying something like "did you forget your password" and asking that a link be clicked to resolve the issue. But instead of solving your problem, it takes you to some advertisement. Paul called that a "link redirection virus" and said some of them could be very nasty.

He said some viruses come as a "blended threat" with multiple components. You might run an anti-virus check and get rid of some of it but other parts remain to reenable the threat. He recently had to deal with the pihar rootkit. Sometimes a rootkit is just one element of a virus. Rootkits infect "behind or below" the operating system making them more difficult to remove. On previous shows, Paul talked about Tdsskiller and Blacklight, which can be used to remove rootkits. Paul said Symantec also has a tool to remove pihar. <I think this might be it (NPE, Norton Power Eraser). Be sure to read the warning on that page>

Paul said Thunderbird (an email, RSS, newsgroup reader) now has the ability to put in Facebook messenger and a number of other thngs".

Paul noted that various versions of Windows are not true multi-user systems — they only seem that way on the surface. Linux, PS2 and Macs, on the other hand, do keep users completely partitioned off from each other.

Pam called. She's in the process of moving and wanted to know how to find out what choices she'll have for internet service.
– Ask the neighbors.
– Go to the websites of various providers and use their facilities to find if service is available. Try AT&T, SmarterBroadband, Spiral Internet (an agent for Digital Path). SmarterBroadband and Spiral Internet both offer line-of-sight wireless.
– Low on the list is satellite broadband thru Hughsnet and maybe DishTV.
– Internet thru your cell phone service is another possibility, but can be costly and have a limited data allowance (data cap).
– Be aware of the "get out" time, within which you have the chance to try the service and end it without penalty. Also, check the contract to be sure you're getting what you expect. Get it in writing — don't rely on verbal promises.

Paul said callers who didn't get their question resolved on air can email the guys at zen at kvmr dot org. In the email, note if you want your name mentioned during the show. In fact, you can email questions during the show, if you don't want to talk on air.

KVMR has a schedule of its broadcasts here. Glenn thanked all of the KVMR broadcasters & volunteers.

Ellen called. She has dead external drives and an old computer. She wanted to know how to scrub the data off the drives. She took a hammer to her drives, but wanted to know if there's a better way.
– There are software programs to do that but the drives have to be working. They scrub by overwriting the data several times with random bytes. Be sure you get such software from a trusted source — there may be some that harvest your date for nefarious reasons.
– Take the drives apart to get to the platters & destroy them. Some drives may require a special screwdriver called Torx, which you can get on Ebay for $8 or $9.
– Alternately, you can use the platters for wind chimes. Hang them on fishing lines and you might be pleasantly surprised by the sounds they make.
– If you want to scrub the drive in a computer you're selling, a reasonable approach is to reformat the drive & reinstall the operating system.

The Disclaimer
The views and opinions expressed on this show are those of the speakers only and not necessarily those of KVMR, its board, managers, staff or contributors

Michael called. He wondered if microwaving a hard drive would destroy the data. Paul suggested putting a container of water in there too. He thought that the ovens need to dump their energy into an energy sink (the water) to prevent damage. Paul also suggested lowering the drive into a bucket of vinegar while it's connected to a power source and is spinning. The reason for vinegar is because it's conductive.

Michael said he has XP Home Edition and when he right-clicks, sometimes the context menu just briefly flash on and then goes away. He can't get it to stay open on the screen.
– Paul suggested he try a different mouse.
– If you find the mouse is the problem, try cleaning the inside.
– If you decide to replace the mouse, consider the optical type as they have fewer moving parts.

Michael also said he's not had internet service at home because his only option is to use dialup and he's gotten frustrated waiting for pictures to load. Now that he finally has wireless internet available in his area, he and wanted to know if he has to buy a bunch of hardware.
– No. They should provide an antenna modem, which goes on the outside of the house. That will service 1 computer.
– If you want to distribute the wireless signal to multiple devices inside, then you'll need to get a router.
– <For dialup users: you can also turn off image loading in many browsers. You may be surprised how little images add to the content. If you need to see an image, it's usually easy to load just that one.>

Paul searched for the words: windows xp no right click. He found some information at Microsoft in a forum called "groups microsoft public windows xp help". He said Microsoft is more trustworthy than other sites that offer help.

The instructions he found involved editing the registry. He said it's absolutely important to follow instructions when dealing with the registry. And, when reading forum messages, don't stop at the first proposed fix, read the follow-up messages before trying a remedy.

Glenn said his Asus netbook needs to have the operating system reinstalled because it running so slow. He said he found out the it doesn't have a partition from which he can do the reinstall and Asus wanted $50 to send him an installation DVD. He said he'll try to install from an after-market version of XP.

Paul wondered about the experience people have had with Windows 8. You can get a licensed version of Win8 for $39 but he didn't look favorably on the tiling system it uses. The tiles are similar to the apps on the mobile phones but many people hate them on a desktop computer. He said there is an app called Desktop that's supposed to replace tiles with the familiar desktop. There's something similar already built-in to Win8, but you have to look for it.
– If you have the Vista version of Windows, you'd do well to get Win8.
– If you have Win7, he doesn't see a compelling reason get Win8.
– If you have XP, hold on to it as long as it's working.

Glenn asked if one could buy a Windows 8 machine and put XP on it. Paul said it's not easy. Older versions of the PC had only a BIOS (Basic Input Output System), which handled the input/output of the keyboard, mouse, drive, etc. With Win8 Microsoft requires manufacturers to have additional firmware called UEFI (Unified Extensible Firmware Interface). He said it keeps your product code in firmware to make hacking and stealing more difficult.

Paul said one could put Win8 on machines that don't have UEFI if they have enough horsepower to run it. It's just that Microsoft does not allow manufactures to distribute Win8 unless the machine has UEFI.

Daine <day.nee> called. She just got a MacBook Pro with Mountain Lion (operating system) and wanted to know if she can put Windows 8 on it.
– Glenn said Macs that use the Intel processor can handle any version of Windows.
– Paul said he'll have a more detailed answer for her next time.

Paul asked how do you tell if a program you're about to download is not adware or just a demo version.
– Glenn said, if he does a Google search, he looks at the URL of the link to give him a clue about the website it goes to. Otherwise, it's hard to explain what to look for.
– Paul didn't have a good solution either. It seemed all he had to suggest is that past experience with bogus downloads helps to build an intuitive sense for these things.

ISPs (internet service providers) are poised to implement a warning system for those suspected of illegal downloading. The ISPs include 5 or 6 of the largest like Comcast, Verizon, AT&T and Cox Cable. "They will, to some extent, permit the monitoring of the traffic coming and going from your internet connection and will launch a complaint against you if one of the copyright stakeholders discovers their movie or intellectual property being pirated". It's called Six Strikes or the Copyright Alert System (CAS).

Paul said a third party is authorized to log into pirate sites like Pirate Bay and monitor traffic. They will look for pirated works and possibly even put up fake content to see who downloads it, though the entrapment issues may limit use of that ruse. "Normally, there's a slap-on-the-wrist fine of $35 if you keep doing it". They may also throttle your connection speed. But you can then get your privileges back after viewing an educational video — similar to driving school after getting a speeding ticket.

Glenn asked for clarification about who does the monitoring.
– The copyright holders gained permission from the ISPs to have contact information of suspected violators provided. <The copyright holders will use this contact info to issue warnings to the violators, I presume>
– The jury is still out about the consequences for the violators.
– Search Google for the words: ISP piracy warnings.
– Pay attention to any warnings you receive.

Be careful about clicking links in emailed warnings — they may be phishing attacks. There's often an increase of such attacks after the news of initiatives like this Copyright Alert System (CAS). In fact, this applies to all email you get. If you get a email warning or notification from your ISP, the alternative to clicking a link is to place a phone call to your provider. Rather than clicking on links in emails, type in the known, good web address for the website in question.

On a related note, Paul again mentioned that hundreds of thousands of Yahoo mail accounts have been broken into. Be suspicious of mail from a Yahoo account even if you know its true owner, as their account may have been compromised.

Over the years, Paul had done an informal survey about what people think is the number 1 security problem. Most got it wrong. From what Paul learned, the number 1 security problem is physical theft — stolen hardware. With the recent increased popularity of flash drives, theft of media is now #1. Be careful what you backup to flash drives — account numbers, passwords and such.

Glenn noted that with their increase of quality and decrease in price, surveillance cameras in the home are a good idea.

That led Paul to talk about the recent Russian meteor and the number of videos documenting it. Due to their failing judicial system and the need to make a case in court after traffic accidents, car dashboard cameras are very popular there. Some use the camera in an Android tablet pointed out the window. The tablet's built-in GPS and clock document the exact location and time of an accident.

Paul again mentioned that he's no too happy with the Android tablet he bought recently. But, he likes the Android on a Stick, which he talked about on the last show and on 1-23-13.

Glenn said he got the Vizio Costar he talked about on last week's show. It's a Google TV device selling for $99. He's not happy with it. He tried to download an app to play content from NBC but got the message that the app was not compatible with his device. While on the air, he got a reply from Vizio saying the apps for NBC & ABC will not work on the Costar because both companies have all of the Google devices blocked. Paul thought that's because the Costar is identified as a Google TV device, not a <generic> Android device (Android is the operating system by Google as opposed to the service called Google TV). It's a branding or licensing issue.

While playing a movie from a flash drive, the Costar would only allow him to Play, Stop and Pause — no fast forward/backward. Paul said there are different movie-playing apps at Google Play and since the Costar is an Android device, he implied an alternate player might work better. Paul said Android has to support so many platforms and so many devices, not all of the apps will work all of the time on all of them.

Paul noted that for Android & iPad you can get the free Kindle app. <It's available for the desktop PC, too> You don't have to have the Kindle to read books, newspapers etc. With the app & an Amazon account you get much of the same content — even a lot of free books. The quality of the display will vary, of course, with the device on which you install the app — it may not be as good as the Kindle.

Glenn wondered if the new Kindle Fire, with its color display, is as good for reading as the regular Kindle. Paul said he's seen one only briefly and he wants to evaluate it further, but the text does look good. Because the Kindle Fire (and its HD version) is pricey, he suggested that a lower-priced tablet <using a Kindle app> may be adequate. And, he said, the Kindle is more like a reading device with Android capability rather than an Android device with reading capability.

Glenn thanked the supporters of KVMR. <To become a member, visit KVMR>

Bonnie Lee called. She wanted to know what information is stored in digital photos and how to access it.
– When you take a picture with an iPhone, there is extra info stored along with the photo called exif data.
– Part of the data is the latitude & longitude of where the picture was taken.
– You can turn off that feature on the iPhone, it's under 'Settings' — look for location services.
– Bonnie is using a regular camera so it probably doesn't store the location data, though a few high-end cameras might.
– Some websites where you upload photos, Ebay or Craigslist, may strip out that data, but check with them to be sure.
– Paul found the website exifdata.com. You can upload a photo and it will tell you what info is stored with it.
– Some software will let you examine a photo's exif data using your home computer. Glenn found Picture Information Extractor at download.com.

Paul offered a tip for those with a smartphone but who want to use a quality camera that doesn't have the exif. Take the same photo with both. The smartphone will record the time & location and the camera takes the picture you'll want to keep. You can match them up later.

When Paul wants to get reliable details on some tech story, like the Copyright Alert System, he'll do a Google search and look for results that come from PC Magazine, Cnet or Techcrunch. Google tends to list the more reliable sources near the beginning.

Continuing the discussion about Glenn's Vizio problems, Paul said he download the Google TV app for his Android device and it works fine. He pays for each video he wants to watch. Downton Abbey is $1.99 per episode, he said, but he doesn't know if you get to keep it or only watch it for a limited time.

Ross called to ask about ZRTP by Phil Zimmerman (creator of PGP). It's supposed to encrypt data between 2 computers on the internet (both have to be running ZRTP). He wondered if it can be used to circumvent the Copyright Alert System (CAS) by disguising the size of the data being sent.
– Paul said that's one of failures of cryptography — it's not straightforward to mask the size of the message. Extra (useless) data would have to be inserted between the useful data.
– Ross said that, supposedly, is what ZRTP does. In that case, Paul said, you have to be careful about exceeding the data limits (caps) imposed by your ISP. <The inserted data adds to the file size>
– Paul said the Copyright Alert System is designed to detect who you're connecting with (your peer in a peer-to-peer connection) but not look at what data is being transferred.
– Paul: "if you encrypt something you better encrypt everything". You'll draw more attention if you look like you made a special effort than if you encrypt everything by default <I think is what he meant to say>.
<General info on ZRTP; see "External links" on that page.
This place has ZRTP apps for Android; iPhone; PC desktop (I'm not endorsing this site — buyer beware)>

There was some talk about anonymity and trust. Some highlights…
– Anonymity can come from disappearing in the crowd. By not having a phone or the internet, etc. you draw attention to yourself.
– Use your judgment about giving true information when signing up for some internet services — they're likely to let you in anyway.
– You can be more revealing in proportion to the trust you have. <Banks, utility companies, close friends>
– You don't always know how much to trust. Yes and No are not the only answers to the question of trust. Error on the side of caution.
