Google Plugin Error 1612

Google Talk
Google Voice and Video Chat Plugin (also known as Google Talk Plugin) is needed to make telephone and video calls (free as of this writing) from within Gmail. Unfortunately, the plugin can become corrupted, which results in a prompt to install it, but that can result in Error 1612 over and over. The description makes it sound like a download error, but it can actually be due to corruption of the installation on Windows. Worse, there is no good way to uninstall it (for which shame on Google)!

The solution may be to use the Microsoft Fix It tool to Fix problems that programs cannot be installed or uninstalled. Look for Google Talk Plugin in the list of items to install or uninstall. Then after fixing that, try again to install it.

Wireless HDTV Video (original)

Chromecast
See Wireless HDTV Video (update)

The ability to beam video to a HDTV screen without wires has been promised for quite some time, but the product methods on offer (DLNA, Miracast, Wi-Fi Direct) have proved to be disappointing, complex and/or problematic. Two current examples:

Chromecast

With mighty Google behind it, inexpensive Chromecast would seem a sure winner. But right out of the box it can be problematic because it insists on network capabilities (access to Google Public DNS servers) that make it incompatible with some wireless routers. (See Chromecast Router Compatibility) Past that point things can look good at first blush, as when casting the screen of an Android mobile, or streaming YouTube video. But push it a bit harder and warts appear. Local video (from Android mobile or Chrome browser) is limited to 720p and relatively low bit rate by default, with poor quality, and even when pushed to its limits, quality is still only mediocre at best. So if you care about video quality, Chromecast is really just another Internet streaming option.

DLNA

Many "smart" HDTV sets claim DLNA Player support, which should make it possible to beam video to them over a network connection (wired or wireless), and the ubiquitous Windows Media Player includes DLNA Server support. (See Media Streaming with Windows 7) But try to make it work and you're very likely to run into compatibility problems, since many HDTV sets are very fussy about what video formats they will (and will not) play, and Windows Media Player does not support transcoding between formats. (While there DLNA servers that can transcode on the fly, they can be difficult to set up, and the resulting quality is often mediocre. Your best bet is to use Handbrake to transcode to MPEG-4 in advance.) But even when it works, video quality is noticeably inferior to a wired HDMI connection.

Bottom line: Beaming of HDTV video without wires remains a work in progress. For best quality use a wired HDMI connection.

Record Radio Online

I've previously described how to record Internet radio with a computer using VLC Media Player. (See Record Internet Radio.) This can be invaluable for time shifting programs not available as a podcast.

Recording can also be done without a computer using the DAR.fm Web service.
  • With a Free account, you can schedule a single program to be regularly recorded, and (only) listen using a Web browser on a computer.
  • With a Pro account (starting at $40 per year), you can record 5 or more shows, and also download them and/or stream them to smartphone.
Recordings are broken up into 15 minute segments. You can play them continuously with a playlist, or by joining (and optionally cutting) them with a tool like mp3DirectCut (freeware for Windows, works without quality loss).

UPDATE (6/2015): DAR.fm prices have greatly increased. The Free account has been eliminated, and the Pro price to record up to 5 shows has more than doubled from $40/year to $90/year. The future of the service is questionable.

Cell Phone Bargain

Moto G
Great phone. Great service. Great value.

No contract cell phone service is much less expensive than contract service, but you have to buy your own cell phone (instead of having the cost bundled into contract phone service), and an up front cost of several hundred dollars can be a significant drawback.

The Moto G, a breakthrough Android smartphone with solid specifications and an amazing price of only $180 that made no contract cell phone service much more attractive, is now even better: Net10 Wireless has a special Moto G (1st generation) price of only $120 (as of this writing) that makes it a steal! Although it's not LTE (see below), its 4G speed is still quite respectable.

Net10 Wireless is one of the best values in cell phone service, with unlimited domestic phone, text, and data (as of this writing) for only:
  • $40 per month with a small amount of high speed data (500 MB)
  • $45 per month (on auto-refill) with a substantial amount of high speed data (3 GB)
Tips:
  1. With Net10 Wireless, you can choose either the AT&T or the T-Mobile network. AT&T tends to have better network coverage. T-Mobile tends to have higher data speed.
  2. The LTE version of the Moto G (with faster data speeds) is available on Amazon for $190 (as of this writing).

Wi-Fi on the Water

Alfa Marine USB Wi-Fi
If you're on a boat, and there's Wi-Fi available ashore, but your computer can't get enough signal for a usable connection, the outdoor waterproof Alfa Marine USB Wi-Fi Adapter can be a good solution.

The pictured module has an integrated 12 dBi long-range antenna. Although the antenna is directional, the pattern is wide enough that pointing is not critical, and a fair amount of boat movement is tolerated. With clear line-of-sight and a good antenna at the other end, range can be a mile or more.

The module mounts to something like a stanchion or mast on deck by means of stainless hose clamps or plastic zip ties, with a USB cable running to a computer below deck. Although the cable is limited to 15 ft (5 m) by the USB standard, a USB extension cable may be used for an additional 15 ft.

Available on Amazon for only $35 (link) as of this writing. Drivers provided for Windows, Mac OS, and Linux.

(Beware of cheaper off-brand units with exaggerated claims of antenna gain or range. Most are junk.)

Tip: Only one computer is supported, but if the computer has Wi-Fi, software can turn that Wi-Fi into a hotspot for wireless devices. Sharing over Ethernet (cable) is also possible.

Extend Wi-Fi Coverage

NETGEAR PLW1010 Essentials
Wi-Fi radio signals all too often fail to adequately cover the desired area, not only because radio signal strength decreases with distance, but also because radio signals are attenuated (blocked) by walls and floors.

The first thing to try is to locate the Wi-Fi base station (also known as gateway, wireless router, or wireless access point) as near to the center of the desired coverage area as possible in order to minimize distance, but that may be difficult or impossible, or simply not enough.

If that fails to solve the problem, many people then try so-called wireless range extenders (actually wireless repeaters), but these devices tend to work poorly:
  • Additional radio traffic cuts wireless network speed by more than half.
  • Interference with other wireless networks may increase, often a problem.
  • May be difficult to locate midway between Wi-Fi base station and weak coverage area.
A better solution usually (but not always) is powerline networking, using existing electrical power wiring (instead of radio) to carry network signals between modules, a base module (left unit in accompanying picture) located next to the Wi-Fi base station, connected by cable to a LAN port, and remote module(s) (right unit) in weak coverage area(s), broadcasting secondary Wi-Fi signal(s).

For best results it's important to select name brand products conforming to the AV2 (AV600 or better) standard, such as the TP-LINK TL-PA6010KIT, which includes both a base module and a remote module.
It's important to plug these units directly into wall outlets because many power strips and so-called surge protectors interfere with network signals.

Testing powerline networking is easy: plug the modules into outlets at the desired locations, and green "sync" lights will turn on if they work. (In some cases they won't work due to electrical wiring issues, so be sure to get a return privilege.) Then it's just a straightforward matter of setting up the secondary Wi-Fi signal.

Note:
  • Best Buy stores often stock Netgear Powerline (link). 
  • B&H is a great low-cost source of such products (link).

Extremely Good Travel Mug

Contigo Extreme
The great majority of travel mugs on the market are mediocre at best. Poor insulation fails to keep beverages hot or cold. Lids leak. Fragile plastic breaks.

Fortunately, there is a superior travel mug: Contigo Extreme.
  • Vacuum insulation keeps beverages hot or cold for hours
  • Rugged and durable stainless steel construction
  • Leakproof lid that's actually leakproof (and dishwasher safe)
  • Comfortable carabiner clip handle attaches securely
  • Tapered to fit in standard cup holders
  • Generous 16 oz capacity
  • Lifetime guarantee
  • Sold by Target at discount
Some longtime fans of this mug complain that it has been cheapened over the years, but even if true, it's still arguably the best travel mug available, and the lifetime warranty covers any issues that might arise.

Pandora One Bargain

Pandora One Gift Card

Pandora is one of the best streaming music services, offering both a an ad-supported "free" service and a paid ad-free service (a so-called "freemium" business model). A principal Pandora differentiation (as compared to competing services like Google Music All Access, iTunes Radio, Rhapsody, and Spotify) is Music Genome Project technology, which does a good job of selecting music that is similar to music you already know and like.

In the beginning the free Pandora service was attractive given ads that were relatively few and unobtrusive, but over time ads have become both more frequent and more obtrusive, to the point where they are now downright annoying, which of course pushes subscribers toward the paid service.

That wasn't so bad when the paid service was $36/year or $4/month, but Pandora ended the annual subscription option and raised the price of new subscriptions to $5/month (⅔ more expensive than the original annual subscription on a monthly basis).

Fortunately, there is still a way (as of this writing) to get the original $36/year subscription price: Pandora One Gift Card at Target.com (not in Target stores). Where you receive your gift card(s) in the mail, you can add them to your Pandora account by activating them here.

This probably won't last forever, so you might want to stock up with more than one card.

Update (4/2016): Pandora One Gift Card at Target.com is no longer available.

Safer Online Dating

1. Open a new free Google Gmail account just for online dating (nothing else). You can forward it to your regular email for convenience, but always answer from the dating Gmail account. That way your email can't be used to find you, and you can always close that account if you encounter a real creep.

2. Buy a cheap prepaid cell phone just for online dating (Net10Page Plus, etc), and pay by cash (not credit card). You can forward it to your regular cell for convenience, but always call from the dating cell phone. That way your phone number can't be used to track you down, and you can always drop it in a dumpster (or donate it to charity) if you encounter a real creep. (Bad guys call this a "burner phone".) Or use the Burner app.

3. Always do a first meeting in a very public place, make it something cheap (like coffee or tea), and buy your own. That way you'll be safe, and able to walk away whenever you want with no feeling of obligation.

4. Always drive your own car or use public transport. Never ever give out your home address until you know someone really really well.

5. Post new photos, not photos you've used anyplace else (Facebook, Flickr, LinkedIn, etc). Otherwise people can use image search to find and associate these other places.

6. Use a nickname for online dating, not your real name, to make it harder for someone to look you up online.

7. Do not use your real city of residence in your dating profile -- use a nearby city instead to make it harder for someone to look up your home address.

8. Never even start with anyone that doesn't have at least one good photo posted. Having no photos or only bad photos is a big red flag.

9. When someone gives you a phone number, Google it -- you'll often learn worthwhile things. ;)

Vehicle Mount for Cell Phone

Mountek nGroove Grip Universal
Smartphones can be excellent while driving, especially in vehicles lacking comparable electronics, providing such hands-free services as:
  • Phone calls
  • GPS location and turn-by-turn navigation with voice prompts
  • Playing music and podcasts
  • Streaming Internet radio
This works best with a mount that holds the smartphone where it can be easily seen and used. Common mounts attach to windshield or dash with suction cups that can loosen over time and which often obstruct the view. Mounts that attach to air vents partially block the vents and can make them hard to adjust.

If your vehicle has a CD player, a better mounting solution may be the Mountek nGroove Grip Universal, pictured mounted in a Volvo S60 holding a Google (LG) Nexus 5 (recommended) with a Diztronic protective case (recommended). This mount is attractive, solid and secure, tilts and rotates, attaches and removes easily, with no need to remove or modify protective cases. (If you never play CD discs, you can leave the mount attached.)
  • Cable is power from a PowerGen Car Charger (recommended)
  • Connection to car audio is by Bluetooth in the picture, but cable could be used instead
  • App displayed is CarHome Ultra, made especially for driving (recommended)
