Netcraft's latest (January 2002) web server survey (www.netcraft.com/survey) still has Apache in the lead among active sites with a 63.69% share, up 0.35%. Microsoft IIS holds a 26.07% share, down 0.55%. Both saw increases in numbers of servers. iPlanet was third with 2.99%, and Zeus was fourth with 2.16%. Both were essentially unchanged.
Netcraft also reported “mixed fortunes” for Sun's Cobalt subsidiary, which sells Linux-based web servers. “Although numbers of IP addresses on Cobalt machines has increased over the last year, their share of the total number of sites running on Linux has fallen, almost relentlessly month on month.” Netcraft notes that two large customers have switched from Cobalt to conventional Linux machines. Texas ISP Everyone's Internet recently announced “the largest single purchase ever by an independent North American ISP from Cobalt”. The company bought seven hundred Cobalt RaQ servers.
Q1. Whose web site is titled “The homepage of a WWW-illiterate”?
Q2. Torvalds commenting on a certain person's rant about open-source software: “I'd rather listen to Isaac Newton than to X. He may have been dead for almost 300 years, but despite that he stinks up the room less.”
Simple question: who is Torvalds talking about?
Q3. What's the collective noun for a group of penguins?
Q4. Vinod Valloppillil of Microsoft certainly said quite a few flattering things about Linux:
“Linux represents a best-of-breed UNIX that is trusted in mission-critical applications.”
“Linux has been deployed in mission-critical environments with an excellent pool of public testimonials.”
“I previously had IE4/NT4 on the same box, and by comparison the combination of Linux/Navigator ran at least 30-40% faster when rendering simple HTML + graphics.”
Where did Vinod Valloppillil make these flattering comments about Linux?
Q5. We all know Linus was studying at the Department of Computer Sciences, University of Helsinki when he started working on Linux. But what is Linus' mother tongue?
Q6. Ray Tomlinson, a scientist working at BBN, Cambridge achieved a unique distinction in 1971. What was it?
Q7. A word origin question: William Gibson, in his famous novel Necromancer, coined a word that has become very popular. What word?
Q8. What is Linus Torvalds' middle name?
Q9. Which application is Linux Journal talking about when it says “You know your program has caught on when people start to use its name as a verb”? Later in the same article LJ says, “It's no coincidence that the spread of this application has coincided with Linux distributions finally paring down the menu of potentially exploitable services offered by default.”
Q10. The author of this seminal work ends his acknowledgements with “and AT&T Bell Labs for firing me and making this all possible”. While talking about this book, Wired magazine says, “The book the National Security Agency never wanted to be published.” Too many clues already, but name the book and author.
questions and answers.
A1. Linus Torvalds—check it out at www.cs.helsinki.fi/~torvalds.
A2. Craig Mundie, Microsoft Senior Vice President.
A3. A waddle of penguins or a raft of penguins. A group of penguins in water is called a “raft of penguins”, while a group on ice is called a “waddle of penguins”. This was decided at the 4th International Penguin Conference in Chile in September 2000.
A4. In the (in)famous Halloween Documents. In case you haven't heard of the Halloween documents, go to www.opensource.org/halloween/halloween1.html.
A5. Though Linus grew up in Helsinki, the capital of Finland, his mother tongue is Swedish. Finland has a significant Swedish-speaking population and they call themselves finlandssvensk.
A6. He sent the world's first network e-mail. And according to him, the first e-mail most probably was something as innocuous as QUERTYIOP.
A9. Fyodor's Nmap. The article is the Editors' Choice Awards [December 2002 issue of LJ, /article/5525], and Nmap was judged the best security tool.
A10. Applied Cryptography by Bruce Schneier.
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
