Four young friends (Blaise, Charles, John, and Konrad), who met at a LAN party, have recently taken jobs at the same technology services firm. All of them work in the web development division and they were all hired as junior programmers because of their inexperience. They all work with different languages (AJAX, Perl, PHP, and Ruby on Rails (RoR)), different information systems (JSON, MySQL, plain text, and XML), and have been using those languages and systems a differing amount of time (3 months, 5 months, 6 months, 9 months).

Using the clues provided, can you figure out who has been using what language with what system for what amount of time?

1. MySQL has been used longer than RoR.
2. The four friends are John, the one who uses PHP, the one who has been at it for 9 months, and the one who uses plain text.
3. Blaise is happy he doesn't have to work with Perl.
4. Plain text has been used longer than PHP, but not as long as AJAX.
5. One of the languages start with the same letter as its corresponding system.
6. Charles has been working with his language and system longer than John, but not as long as the person who uses AJAX.
7. The four information systems are XML, the one used with PHP, the one that's been used for 6 months, and the one that Konrad uses.
8. JSON has not been used the most amount of time and XML hasn't been used the least amount of time.
9. The four languages used are AJAX, the one used for 5 months, the used by Charles, and the one used with JSON.

The programming languages do not necessarily match up with the most realistic information systems.

I like it, even if some of the clues are repeats.

No clues are repeats, but some are repetitive in that they give you something you should have already known in addition to new information.

Bravo! It's another one of those that I had to read again to find out, "What in the world did I forget?" I did find it.

It was well done. After putting in the info in the grid, I never had to look back for missed info. The answer just fell out from the grid.

Very interesting and well done What is JSON?
Aug 09, 2008

nicely done! Not too hard, but fun. Of course I had a "duh" moment when I marked an O where there should have been an X which caused me to switch 2 times...

JSON is a method of storing text information in a flat file. Many people consider it better than XML for many data tasks.

Thanks for making, I haven't made a teaser yet so I'm not one to judge, but I am a little mystified as to why this one has such a hard rating? All answers are in the grid, there is no need to go back to earlier clues, and mine was complete ( and correct ) before the last clue. I am thankful for the effort, and for sharing Thanks again
