Surge Suppressors

SurgeX Power Pro
Many surge suppressors, particularly the inexpensive ones commonly found at retail, do a poor job of protection. Surge suppressors built into quality uninterruptable power supply (UPS) units tend to be better, but for best results, use commercial grade surge suppressors -- more expensive, but worth it.

At a minimum, make sure that any point of use surge suppressor is UL 1449 listed/recognized at a suppressed voltage rating (SVR) of at least 330 volts. For endurance, the surge suppressor should also be Classified in Accordance with ANSI/IEEE C62.41-1991, Recommended Practices. (UL 1449 listed products are not necessarily classified for endurance.)

Good commercial grade surge suppressors include:
One of the best commercial grade values is the SurgeX Power Pro, available through Home Depot for $99 (as of this writing).

Tripp Lite Isobar, some of the best standard grade suppressors, are available through Amazon.

Great Coffee by the Cup

Pod-type coffee brewers (e.g., Keurig, K-Fee, Nespresso) are all the current rage, but they trade aroma and taste for convenience, chiefly because you're not getting freshly roasted and freshly ground coffee, which are the keys to a great cup. In addition, the brewing machines can be quite expensive. Fortunately, there are simple and inexpensive ways to get great coffee by the cup with easy cleanup:

Aerobie AeroPress

What makes Aerobie AeroPress special is the plunger for forcing brewed coffee out of grounds with air pressure, thereby ensuring full extraction for maximum strength, espresso-type drinks in a hurry.

Clever Coffee Dripper

What makes Clever Coffee Dripper special as compared to a standard cone filter holder or coffee maker is that ground coffee is kept in contact with water for the entire brewing period by means of a valve in the bottom of the holder, which ensures full brewing like a French press, but without the problem of sediment, especially if a paper filter is used (rather than a gold metal filter).

Grinding

For best results use freshly ground coffee, ideally by grinding your own with a good burr mill -- see Coffee Grinders under $100.

Powered (Active) Speakers with Remote

Boston Acoustics Soundware XS Digital Cinema
Samsung TVs have fixed audio out level that cannot be changed by remote control, so to have remote volume control of external speakers, you need to use:
  1. Receiver or home theater system with remote
  2. Soundbar with remote
  3. Powered (active) speaker system with remote
Option #3 is difficult, because there have been few good yet affordable powered (active) speaker systems with wireless remote, and most that previously existed have been discontinued (e.g., Creative I-Trigue L3800, Klipsch iFi, Onkyo HTX-22HDX). But, as of this writing, the Altec Lansing PT6021 (or similar SLS6221) is available on both Amazon and eBay. (Much more expensive options are the Audioengine 5+ and Bose CineMate Series II.)

Update 1: Unfortunately, the Altec Lansing PT6021 does not live up to its specs and is therefore not recommended:
  • AC hum is a problem, especially during soft passages, as acknowledged in the User's Guide: "Some low hum may be detected when your speaker system is powered on without an audio source playing, or when the volume is set at an extremely low level." (That's simply unacceptable.)
  • Sound quality is mediocre, lacking in clarity. 
Klipsch ProMedia 2.1
Update 2: Boston Acoustics Soundware XS Digital Cinema is an excellent more expensive option, but can be found (currently) for as little as $180, making it a great bargain.

Note: If you don't need remote volume control, try to find a good used Klipsch ProMedia 2.1 system -- it's head and shoulders above other affordable powered 2.1 speaker systems: dazzlingly clear sound, smooth response with strong bass, and ample volume.

Google Reader Lessons

It's not "OK".

Google Reader was an important tool for aggregation of RSS feeds that facilitated sharing (at least until Google+ was forced into it), and was an important platform for RSS applications. A large number of people invested a great deal of time and effort in it, which is lost when Google abruptly shuts it down.

Google's users deserved better, at least a year of warning if nothing else. But, coming on the heels on so many other abrupt here-today-gone-tomorrow shutdowns by Google, there are lessons here that users would do well to heed: Google is not a reliable provider of services, and cloud computing has an important risk -- when a software company discontinues a product, you may be able to keep using it for a long period of time, but when a cloud service is discontinued, it's game over.

(With Gmail you can use POP or IMAP to migrate to another standard email service. Exporting feeds from Google Reader through Google Takeout is much less helpful.)

As a result, I no longer recommend Google cloud services.

p.s. The irony here is that this blog is hosted by Google -- how long until Blogger gets the axe?

Fix Windows File Association Issue

Windows file associations, which associate a given file type (extension) with applications, are normally set automatically, either when applications are installed or by the applications themselves.

File associations can usually also be set (or changed) by right-clicking a file of that type, choosing Open or Open with, then selecting the application, browsing to the application if necessary. But sometimes that process fails.

The most common cause of this failure is incorrect registration of the application, particularly when a different version of the application was installed previously. To correct this problem:
  1. Click start; type "regedit" to find it; then right-click the program and Run as administrator.
  2. Navigate Computer > HKEY_CLASSES_ROOT > Applications, and find the application exe.
  3. Navigate shell > open > command, and check the exe path in the (Default) string.
  4. If the path is not correct, change it to the correct path of the application exe.

Why Netbooks Flopped

Netbook computers seemed like such a good idea: low-cost, compact, portable computers with good battery life and enough power for common tasks. At first sales took off reasonably well, but we can now see it was a cycle of rise and fall. Why did they ultimately fail?

I think the answer may be best illustrated with an anecdote: When updating a typical netbook that hadn't been used in about 9 months, it took over two hours to apply the accumlated Windows XP patches, and another hour to update applications. And that was by an expert. Simple tasks like populating the Add/Remove Programs window that should have taken seconds instead took many agonizing minutes. It's just too painful to endure. The value proposition just isn't there.

But that's not the fault of the netbook -- it's the fault of Windows, which takes way too much maintenance and tweaking, and which needs much more powerful hardware to run decently!

But there is hope for the machine: Chromium OS Vanilla, the open source development version of Google Chrome OS, "a lightweight, lightning-fast operating system for your netbook, laptop or even desktop. With the familiar environment of Chromium/Chrome, the entire web is at your fingertips in seconds. HTML5 is fully supported, allowing you to enjoy the very best that the web has to offer." It has the potential to turn the netbook into a speedier, easier to maintain Chromebook. Stay tuned!

Chromebook Pixel: close, but no cigar

The Google Chromebook Pixel is presumably meant to be the best that a Chromebook can be, and while it is an attractive package with a killer screen, it has a number of flaws that just don't belong in a premium-priced machine:

9. Bluetooth: 3.0 is adequate, but it should have been 4.0 for the advances in power conservation (battery life).

8. DisplayPort: DisplayPort is adequate, but HDMI would have made more sense.

7. Storage: 32GB isn't enough for a premium machine; 64GB should have been the minimum.

6. Memory: 4GB isn't enough for effectively managing many open tabs; 8GB should have been included.

5. USB: 2.0 is painfully slow; 3.0 is becoming essential for high speed devices.

4. Gloss: Glare is a problem on the glossy screen; should have been non-glare. 

3. Weight: At 3.35 lbs it's about a pound heavier than it should be, almost as heavy as a light notebook computer.

2. Keyboard: Just backlit isn't enough, a premium machine warrants a premium keyboard (like the Lenovo ThinkPad).

1. Battery: 4 hours of typical use just doesn't cut it, needs to be 8 hours (at least double).

As the saying goes, "Never buy version 1.0!" And Chromebook Pixel is no exception. Perhaps Google will get it right with version 2.0.

Tequila Bargain!

No more Zapopan at Trader Joe. See Updates below.

To make a great Margarita you need great tequila, and most of the widely-available affordable tequilas (including name brands) are dreadful mixtos. (See Types of Tequila) Fortunately there is a very good tequila that won't bust your budget: Zapopan, sold by Trader Joe's for only $10 per liter, both Blanco (lighter) and Reposado (richer and smoother). It's generally better than anything else under $20, and stands up well to anything else under $30.

Classic Margarita
  • 3 oz tequila
    100% agave, reposado preferred
  • 1 oz triple sec*
    good quality, orange curaçao also works well
  • 1 oz lime juice**
    unsweetened, preferably fresh, Mexican/Key lime for extra flavor
Shake with cracked ice, and serve in rocks glass, over cracked ice, without salt.
For more sweetness, add more triple sec (or agave nectar).
Great accompaniment to guacamole!

Drillaud Triple Sec
Update (12/2015)
: The price of Zapopan has gone up to $12 per liter, but that's still a great bargain!
 

Update (8/2017): Alas, Trader Joe's no longer carries Zapopan, and the replacement tequila doesn't measure up, but Zapopan can still be found at Bitters+Bottles. The price is higher, but it's still a great bargain. Only Blanco is stocked, but Reposado can be ordered.

Update (5/2020): In California, try Mission Wine & Spirits (in Pasadena), which ships to California addresses: $19.95 for 1L (still a bargain).

Update (6/2021): Mission Wine & Spirits price has gone up so much (now $25.99 for 1L) that I recommend the alternatives below.

Tequila alternatives (easy to find)
:
  1. Olmeca Altos Reposado
  2. Lunazul Reposado (bargain)
  3. El Jimador Reposado
  4. Kirkland Signature Reposado (not the Silver)
* Triple Sec recommendations:
  1. Drillaud (excellent)
  2. Mr Stacks 60 Proof (bargain)
  3. Hiram Walker 60 (not the lower proof)
  4. Patrón Citrónge and Cointreau are good but overpriced
** Key (Mexican) Lime Juice:
  1. Florida Key West 100% Authentic Key Lime Juice
  2. Nellie and Joe's 100% Key Lime Juice (not the similar Key West Lime Juice)

Record Internet Radio

VLC as a Recorder
Tip: You can record without a computer using an online service. See Record Radio Online.

Tip: You can transcode streams to make them easier to record. See Transcode with VLC.

VLC media player (free open source cross-platform multimedia player and framework) is a great way to listen to Internet radio (streams). All you need is a streaming URL (often obtainable from the source website; e.g., http://18543.live.streamtheworld.com:80/KUSCMP96_SC from KUSC) which you open in VLC with Media > Open Network Stream. To save a source for future listening while it is playing, just drag the Title and drop it onto the Media Library.

Recording a source while it's playing is quite easy: View > Advanced Controls to make the recording control available; click on the red record button circle to record; and click again to stop recording. The recording file will be appropriately named and (on Windows) saved in your Music folder.

Scheduling recordings for times when you're not at your computer can be done with (a) the Task Scheduler built into Windows and (b) the VLC command line interface. Start by testing your recording command in a Command Prompt window, with the following four elements separated by spaces:
  1. Complete path to vlc.exe; e.g.,
    "C:\Program Files\VideoLAN\VLC\vlc.exe"
  2. Stream URL; e.g.,
    http://playerservices.streamtheworld.com/pls/KUSCMP128.pls
  3. Recording duration in seconds; e.g., (for 60 mins)
    --run-time 3600 vlc://quit
  4. VLC record parameters; e.g.,
     --sout="#std{access=file,mux=raw,dst=Recording.mp3}"
The record parameters above assume the stream is in the most universal MP3 format. Where a source has multiple stream formats available, choose MP3 to avoid problems; to try recording some other format, use the appropriate file extension (instead of .mp3). You can of course change the file name from Recording to whatever you might prefer. To create unique file names with date and time, see VLC Documentation: Format String; e.g., Recording_%Y%m%d_%H%M

Complete example with date and time (single line):
http://playerservices.streamtheworld.com/pls/KUSCMP128.pls ‑‑run‑time 3600 vlc://quit ‑‑sout‑file‑format ‑‑sout="#std{access=file,mux=raw,dst=The_Record_Shelf_%Y‑%m‑%d_%H%M_(KUSC).mp3}"

Putting them all together on a line in a Command Prompt window should launch the VLC GUI and create the recording file. After VLC has completed the recording and quit, double-click on the recording file to play it, or open it in VLC. When this is working properly, you can move on to scheduling:
  1. Open Task Scheduler
  2. Click Create Task
  3. On the General tab:
    1. Enter Name (e.g., My Stream)
    2. Select Run whether user is logged on or not
  4. On the Triggers tab, click New:
    1. Enter desired schedule
    2. Check Stop task if it runs longer than: and enter twice desired recording duration
    3. Make sure Enabled is checked
    4. Click OK
  5. On the Actions tab, click New:
    1. Action: Start a program
    2. Program/script: complete path to vlc.exe (1st item above); e.g.,
       "C:\Program Files\VideoLAN\VLC\vlc.exe"
    3. Add arguments (optional): 2nd and 3rd items separated by a space; e.g.,
      http://playerservices.streamtheworld.com/pls/KUSCMP128.pls --run-time 3600 vlc://quit --sout="#std{access=file,mux=raw,dst=Recording.mp3}"
      (Note: Display of line above may be truncated!)
  6. On the Conditions tab, set whatever options you wish
  7. On the Settings tab:
    1. Set Stop the task if it runs longer than: to twice desired recording duration
    2. Check If the running task does not end when requested, force it to stop
  8. Click OK to save the task
  9. Test the task by selecting it in the Task Scheduler Library:
    1. Click Run to start the task
    2. Click End to stop the task
    3. Check recorded file
  10. Close Task Scheduler
