Shopping on Penguins
I was pointed recently to Zappos as a near-perfect example of a company that brings the principles of open source to business. Its site is inventive and fancy (as you'd expect a clothing retailer to be), but not a triumph of design over utility. What's more, it's fast. I can check Web site responsiveness with some confidence, because our little apartment near Boston has 20Mb/s symmetrical service from Verizon FiOS (that's fiber, and pretty cheap, considering), and the speeds I get at the office I share at Harvard are more than twice that.
So I decided to see what they were running that site on, by checking with Netcraft.com's “What's that site running?” service. The answer was Linux. Zappos itself is in an Akamai Netblock, and of the 13 other results (all foo.zappos.com), the results for OS were Linux or “unknown”.
Then I decided to look beyond Zappos to other on-line retailers. Here are the results for the top ten, as listed by InternetRetailer.com, with sales volume numbers in parentheses. Results for companyname.com are first, and other results for each company are summarized in text (Netcraft gives results in lowercase):
1. Amazon.com Inc. ($14.8 billion): linux.
2. Staples Inc. ($5.6 billion): linux, through akamai.
3. Office Depot Inc. ($4.9 billion): the top result is linux for www.officedepot.com, but officedepot.com (without the dubs) is windows server 2003. Other foo.officedepot.com sites are a mix of the two and “unknown”.
4. Dell Inc. ($4.2 billion): f5-big-ip, though l.dell.com (Dell laptops) is linux and a couple of foo.dell.com sites are “unknown”.
5. HP Home & Home Office Store ($3.4 billion): hp-ux.
6. OfficeMax Inc. ($3.2 billion): f5-big-ip, with a mix of solaris, windows server 2003, linux and “unknown” among other officemax sites.
7. Apple Inc. ($2.7 billion): “unknown”, but the company uses linux through akamai for a number of foo.apple.com sites.
8. Sears Holding Corp. ($2.6 billion, includes Sears.com and Kmart.com): for sears.com, linux, plus some “unknown”, solaris, f5-big-ip and windows server 2003 for sears.com.mx. For kmart.com, linux (through akamai), plus linux (with and without akamai) for various foo.sears.com sites. Kmart.com.au is windows 2000. Most of the rest are linux, plus a couple “unknown” and one f5-big-ip.
9. CDW Corp. ($2.4 billion): the top result is linux for www.cdw.com (through akamai). cdw.com (sans dubs) is f5-big-ip. The rest are a mix of linux and f5-big-ip, with one windows server 2003.
10. Newegg: windows server 2003, though linux shows up in five out of the nine foo.newegg.com results.
Although that summation is far from a complete picture, or even a completely accurate one for this Top Ten, it's clear that the picture can't be painted without linux as the most primary color.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
