Top Websites Running Linux (2015)

In the past I have posted articles which showed what the most popular websites in the world were running as a server OS.  It's been a few years, so I decided to check again.

As last time, I am using Alexa and Netcraft as tools to see website rankings and which server OS is being used (if known).

Ranking Site OS
1 Google Linux
2 Facebook Linux
3 YouTube


4 Baidu unknown (was Linux last time)
5 Yahoo Linux
6 Amazon unknown, probably Linux
7 Wikipedia Linux
8 Qq Linux
9 Twitter Linux
10 Linux

As was the trend a few years ago, Linux is the clear winner again, and even the other sites are almost certainly Linux, due to clues and articles found elsewhere, as well as their history.

Some other interesting (cherry-picked) sites from the top 100:

  • #14 - LinkedIn .... Linux
  • #17 - Ebay .... Linux
  • #20 - Bing ..... Windows server
  • #31 - ..... Linux
  • #33 - Reddit ...... Linux
  • #37 - Paypal ...... Linux
  • #40 - ...... Linux (I found this interesting, since Mac OS is Unix!)
  • #41 - Tumblr ....... Linux
  • #51 - Netflix ...... Linux
  • #81 - Dropbox ...... Linux
  • #99 - Adobe ...... Linux


While it's true that these sites were cherry-picked by myself, I went with popular sites that users would recognize.  Clearly, Linux is still the most trusted server OS out there for websites.


Keep a Computer In Your Desk Cabinet Without It Overheating

This is a bit of a DIY project.  I'm going to show you how to keep a computer in a desk or cabinet, but we're going to install an external fan in the cabinet to keep the computer from overheating.  (And we can do it for $15 - $25, depending on your setup).

If you've ever tried to keep a computer (or PS3, PS4, Xbox, etc) in a cabinet or other enclosed space, you know they can get pretty hot.  And that can eventually kill your computer.

First things first:  Download a program call SpeedFan.  This program reads temperature sensors on your computer and tells you what they are.  It's the only way we're going to be able to tell if your computer is getting too hot.

Easily Scan to PDF

In the business world, we frequently have a need to create PDF documents which can then be emailed around (for example, contracts and proposals).  The alternative would be to use an old-fashioned fax machine; something most average users do not want to keep up with.  However, many scanning programs do not make it easy to save a multi-page PDF document, instead forcing you to deal with several JPG files or something similar.

I would like to introduce to you my favorite method of scanning to PDF:  "NAPS", which stands for "Not Another PDF Scanner."  It's free, simple, and works with every scanner I've found.  Once you scan your pages, you can easily reorder them if you like, and then save the collection of pages to PDF (or directly email if your workstation is set up with an email client).

Make Spotify Start Playing Over Bluetooth When You Get In Your Car (or any other BT device connects)

I know I'm a little late to the party, but I just recently got a Bluetooth-enabled radio installed in my older car.  I've never had such before, and I LOVE it.  You can get them at Best Buy, and have them installed there for around $70 if you don't want to do it yourself.

I also love Spotify.  The "pro" plan is cheap, especially if you do a family plan which they recently started offering.

Here's my problem:  When my car connects to my Android phone, it starts to play the default Android mp3 player-- and nothing I could do (at the time of this writing) could change that.  I found helpful apps online which would *start* Spotify when the car connected, but nothing that would make it start *playing*.  I still had to do that manually on my phone.

But then I found a solution (for Android anyway)...

Peacock Rx - Web & Mobile Solutions for Pharmacies

I'm pleased to announce that I have a new service to offer, specifically for pharmacies who need a website and/or mobile app.


Its called Peacock Rx.

The system is a subscription-based service, with a low monthly fee.  For that, stores get an android and iOS app which interact with a website, all customized for the individual pharmacy.

Patients can request refills and transfers, read store news blog, call the pharmacy from the app, get directions, etc.

Design Java UI Like Visual Basic

One of the most frustrating and time-consuming tasks in Java is creating basic, boring, ordinary UI.  As in, windows, buttons, scroll bars, text fields, etc.

This is in stark contrast to, say, Visual Basic, where you can just drag and drop elements onto a form, and what you see is what you get.  In Java, if you want anything other than just the basics, you're going to have to do a lot of typing.

That is, unless, you are using the WindowBuilder Engine and Eclipse.

  • In Eclipse (3.7 at time of this writing), go to Help -> Install New Software.
  • Enter this address:
  • Download everything listed, then restart Eclipse:

After this, right-click in your project's src folder to create a new item.  Chose "other", then select the "Application Window" under Window Builder->Swing Designer:

Open the file you've created, and notice something cool-- you now have a "design" tab at the bottom of the code window.  Click it.  You now see a screen like so:

Notice it now looks a great deal like Visual Basic?

The True Price of Using LED Lights

LED light bulbs have recently become much cheaper and more reliable, but what is the real price of ownership?  How long do you have to use them before you "break even" compared to traditional lights?  Below, I do the math so you don't have to!

Some caveats:  I am using 60 watts (eqv) as the base measurement, and prices from Walmart.  At the time of this writing, a reliable LED bulb can be bought for $8, a compact florescent for $3.85, and a standard incandescent for about $1.50.

I am using a rate for electricity costs of 11 cents per kilowatt hour.  Your mileage may vary!

Replacement price:  Factored into these values is the assumption that you will have to pay for bulb replacements as well!  An incandescent bulb only lasts for 1,000 hours.  A CFL bulb for about 10,000.  And the LED bulb in question for 30,000 hours.

At 8 - 10 hours of use per day, 10,000 hours represents around 3 years of real-world use.

Let the data begin!

Hrs of use 60W Incandescent 13W CFL 11W LED
1 $1.51 $3.85 $8.00
100 $2.16 $3.99 $8.12
1,000 $9.60 $5.28 $9.21
2,000 $19.20 $10,56 $18.42
3,000 $28.80 $15.84 $27.63
4,000 $38.40 $21.12 $36.84
5,000 $48.00 $26.40 $46.05

So far, you will notice that the clear winner is the 13W compact florescent bulb (it's the "curly-Q" kind.  Notice, too, the false economy of using the cheaper incandescent bulbs.  Their low price is quickly outpaced by their electricity consumption and frequent replacements.

But, where things start to get interesting is once we start measuring hours by the 10-thousand.  This is because CFL's are only rated for 10,000 hours, and now we must replace them every 10,000 hours!

Hrs of use 60W Incandescent 13W CFL 11W LED
10,000 $96.00 $56.65 $55.26
20,000 $192.00 $121.30 $110.52
30,000 $288 $169.95 $173.78*
40,000 $384 $226.60 $229.04
50,000 $480 $283.25 $284.30

* The jump in price for LED at 30,000 is because we must buy another $8.00 bulb, as it is only rated for 30,000 hours.


After 10,000 hours, the cost of electricity & bulb cost is very close for the CFL and LED bulb, differing by only a few dollars.  Personally, I would stick with the LED bulb.  The extra couple dollars in price (every 30,000 hours, or 9 years) is offset by saving me time not having to change any bulbs!

Also, LED bulbs run cooler, contain no mercury, and generally don't shatter because they are encased in plastic instead of glass (usually).

Also, something to keep in mind:  These prices are based on the time of this writing (2014).  LED prices will continue to drop and drop, and their wattage may lower as well, to become even more competitive.


Every Drupal Site Should Be Using Boost

Every Drupal site-- whether 6, 7, or (in the future) 8, should be using the Boost module rather than the default caching system.  If you've never heard of the Boost module, then you're in luck-- that's what the rest of this blog post is about!


Drupal - Slow and a Memory Hog!

When a visitor comes to your drupal site, several things have to take place.  Your web server (probably Apache) realizes it's a request for Drupal.  It then hands off execution to PHP.

PHP (through Drupal's bootstrap) must then include() and execute dozens or even hundreds of .module, .inc, and .php files from the various modules you have installed.

Those modules might make dozens or hundreds of calls to your database, gathering all the data needed to display the page to the user.

Finally, the HTML is created and handed down to the user's browser for display to the user.

As you can see, this is a slow and memory-intensive process!  If your site is even remotely popular, it can slow down your server or even cause you to run out of memory on the server.  Never a good thing.

Best Free Apps for Android - The App

If you are anything like me, you like finding nifty apps for your android phone, but are also too much of a cheapskate to actually pay for such an app unless it's really remarkable.

Well, I decided to assemble the best free apps for android I could find into its own app, where you can download and even launch directly from the app itself.

It's called simply Best Free Apps!, and it was released under my more legitimate software company, Offworld Software.

The list of apps are categorized and hand-curated.  Unfortunately, a lot of free apps on the marketplace lure you in, but then bombard you with advertising notifications or popups.  There's none of that in Best Free Apps!, just a basic banner ad at the bottom.
