Linux is a name which broadly denotes a family of free and open-source software operating system distributions built around the Linux kernel. The defining component of a Linux distribution is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Many Linux distributions use the word "Linux" in their name. The Free Software Foundation uses the name "GNU/Linux" to refer to the operating system family, as well as specific distributions, to emphasize that most Linux distributions are not just the Linux kernel, and that they have in common not only the kernel, but also numerous utilities and libraries, a large proportion of which are from the GNU project. This has led to some controversy.

Linux was originally developed for personal computers based on the Intel x86 architecture, but has since been ported to more platforms than any other operating system. Because of the dominance of the Linux kernel-based Android OS on smartphones, Linux has the largest installed base of all general-purpose operating systems. Linux is also the leading operating system on servers and other big iron systems such as mainframe computers, and is used on 99.6% of the TOP500 supercomputers. It is used by around 2.3% of desktop computers. The Chromebook, which runs the Linux kernel-based ChromeOS, dominates the US K12 education market and represents nearly 20% of the sub-$300 notebook sales in the US. Linux also runs on embedded systems devices whose operating system is typically built into the firmware and is highly tailored to the system. This includes TiVo and similar DVR devices, network routers, facility automation controls, televisions, video game consoles and smartwatches. Many smartphones and tablet computers run Android and other Linux derivatives. What are the answers to this following set of questions: 1. When was the Linux kernel released?

CHAPTER XXIII

AN EVENING AT APPLEYARD

Rankine had got a few days' leave and was spending it at Appleyard. He sat beside Elsie in a corner of the billiard-room, where the party had gathered after dinner. He had arrived during the afternoon, and Andrew was not altogether pleased to see him, although he liked the man. Elsie had suggested that Dick should invite him, and had added that he might as well come when Madge Whitney was there. Since Elsie had not seen Rankine until he arrived, Andrew wondered what she meant; but he admitted that she generally had a reason for what she did.

Nobody had been playing billiards or wanted to begin. Elsie and Mrs. Woodhouse were knitting and the others were talking quietly, while they waited for the evening newspaper.

Presently Staffer made a remark about the Navy, and Madge Whitney looked at Rankine with a smile.

"Don't you feel that you must answer that?"

"I don't know that I can," Rankine answered good-naturedly. "To some extent, Mr. Staffer's right. The Navy certainly occupies the background of the stage, just now."

"It strikes me as being out of sight altogether," Staffer said.

"Well, perhaps that's its proper place. But I expect it will emerge from obscurity when it's wanted."

"We must hope so," Staffer returned. "No doubt, your commanders are waiting for the right moment to make a dramatic entry on the scene; but one imagines that ambitious young officers must find being kept in the background rather galling." What are the answers to this following set of questions: 1. What is the chapter number?
2. What is the name of the chapter?
3. Who was sitting next to Elsie?
4. How was he able to be at the Appleyard?
5. Where was he sitting with her?
6. When did they go there?
7. Who was not happy with his arrival?
8. Who suggested he should be invited?
9. Who should be present when he came?
10. Who was to invite him?
11. What common thing were Elsie and Mrs. Woodhouse doing?
12. What were the others doing?
13. And what were Elsie and Mrs. Woodhouse doing?
14. Who broke the silence?
15. Who made a comment about the military?

(CNN) -- Pausing to catch her breath at the bottom of the mountain, Lindsey Vonn was back in business.

It may not have been fast, it may not have been smooth but it was still a landmark moment for the Olympic downhill champion.

The American skiing star had finished her first race since making a complicated recovery from a knee injury.

Vonn needed reconstructive surgery on her right knee after landing heavily on the opening day of the Alpine Ski World Championships in Austria in February.

She has waited 10 months to go racing again and in November her return was put on ice when she partially tore one of her reconstructed knee ligaments in training.

There were no complications for Vonn on her first competitive return down Canada's Lake Louise course -- but her time did not trouble the leaders.

She finished her run in one minute 59.22 seconds -- more than three seconds off the leading time and 40th overall.

The start of the race had been delayed by hazy cloud and extremely cold temperatures which dropped as low as -36 Celsius. Germany's Maria Hoefl-Riesch eventually came out on top with the quickest time.

Vonn is racing against time to find form and fitness as she attempts to defend her downhill crown at February's Winter Olympics in the Russian resort of Sochi.

There she will aim to emulate the feat of fellow American, Picabo Street, who came back the season after reconstructive surgery to win gold at Nagano in 1998. What are the answers to this following set of questions: 1. What's the name of the athlete the story's about?
2. What sport does she do?
3. Has she competed internationally?
4. Successfully?
