Facebook Announce’s Hackers Cup

This is a pretty cool idea. Facebook is hosting their first ever “Hackers Cup” to hire new employees. I am entering it for sure even if it some of it sounds very challenging for me. I think it will be a fun experiment.

Here is their Question and Answer section:

What is the Hacker Cup?

The Hacker Cup is Facebook’s international coding competition. The contest consists of three online rounds and a final round held at Facebook’s headquarters. This is your chance to compete against the worlds best programmers and potentially win the title of world champion and other awesome prizes.

What prizes can be won?

The top 25 scoring contestants from Online Round 2 will be flown out to Facebook headquarters in Palo Alto, California, USA to compete in the Finals. The onsite finals will happen on Friday, March 11, 2011. Travel and accommodation will be covered by Facebook.

The finalists will be competing for:
1st place: $5,000 USD
2nd place: $2,000 USD
3rd place: $1,000 USD
4th – 25th place: $100 USD

The top 300 scoring contestants in Online Round 2 will get a Hacker Cup t-shirt. A cash prize of equivalent value may be given where required by law, or at Facebook’s discretion. Any duties and taxes (if applicable) are the sole responsibility of the recipients.

For more details on the Eligibility rules and regulations, please review the Term & Conditions.

How many rounds are there?

Qualification Round
The competition commences with a 72-hour Qualification Round on January 7, 2011 at 0:00 UTC (4:00 PM PST) to January 10, 2011 at 0:00 UTC (4:00 PM PST). All registered competitors will be presented with three problems. Only competitors who correctly solve at least 1 problem will advance to Online Round 1.

Online Round 1
Online Round 1 consists of 3 sub-rounds, each lasting 3 hours in length that are offered at different times from January 15, 2011 at 15:00 UTC (7:00 AM PST) to January 16, 2011 at 0:00 UTC (January 15, 2011 – 4:00 PM PST). Competitors who advance to this round can participate in any of the three sub-rounds until they qualify for Online Round 2. The top-scoring 1,000 competitors from each of the three sub-rounds will advance to Online Round 2.

Online Round 2
Online Round 2 begins January 22, 2011 at 15:00 UTC (7:00 AM PST) and will end on January 22, 2011 at 18:00 UTC (10:00 AM PT). The 3,000 competitors will have three hours to solve the presented problem sets. The top-scoring 300 participants from Online Round 2 will receive an official Hacker Cup t-shirt. The top-scoring 25 competitors from Online Round 2 will be notified via email that they have advanced to the final round at Facebook.

Onsite Final Round
Facebook will fly the top-scoring 25 competitors to Palo Alto, California, for the final round of competition on March 11, 2011, where they’ll receive some great cash prizes and other awesome goodies. Out of these 25 finalists, one champion will emerge and be immortalized on the Hacker Cup trophy. Finalists will be responsible for obtaining their own entry visa before arrival in the USA; however, Facebook will reimburse the finalist for any visa application fee and up to $100 USD in travel expenses incurred in obtaining the visa. Save your receipts! Facebook will not reimburse any fees or expenses related to obtaining a passport.

How do you win?

Point Structure
Each problem is worth a single point. The contestant with the highest score wins. Points scored in one round are used only to determine standing in that round. Points do not carry over from Online Round 1 to Online Round 2.

Penalty Time and Ties
If there is a tie in points, the contestant with the lowest penalty time wins.

Penalty Time = Submission time of the last input you correctly solve (time is measured from start of contest)

How does it work?

There are multiple rounds to the Facebook Hacker Cup. The Qualification Round lasts 72-hours. Online Round 1 consists of 3 sub-rounds each 3-hours long. Online Round 2 lasts 3-hours long.

You can use any programming language to solve the problems, using any development environment or text editor, as long as the compiler or interpreter you used for that language is freely available and easy to download and use. Time-limited trials for compilers and interpreters are disallowed. Visual Studio is acceptable as a compiler, since there’s a free version of (almost the same) compiler available, Visual Studio Express. Facebook reserves the right to make further exceptions on a case-by-case basis.

The Problems
Each contest consists of 3 algorithmic problems. The problems will be listed in the panel on the top left side of the page. Click on a problem’s name to view the statement for that problem, which will appear in the middle of the page.

The problem statement will be an HTML file, possibly containing images. It will include one or more sample test cases and will have one input file.

Downloading Input
At the bottom of the problem statement will be a link to download the input file. The timer begins immediately after you start to download the input file. You will have six minutes for to upload the output from your program.

You have one chance, to solve the input. You may resubmit during this time. If you run out of time, you cannot download another input file.

Re-downloading Inputs
You may re-download your input file at any time during the six-minute time period.

What are the Submission Rules and Judging?

After downloading the input file, you will have six minutes to submit the output (along with your source code). There is only one input file, but you can submit as many times as you wish during the six minutes. Your last submission counts as your final answer. You will find out if your answer was correct after the contest.

*Note: You may experience latency issues between your computer and our servers and are therefore advised to submit with an adequate amount of time remaining in your six-minute period.

How We Will Judge Your Submission

1. Minor differences in whitespace are ignored. In particular, every non-empty sequence of whitespace characters (except newlines and non-ASCII characters) is treated as a single space. Unix, Mac and Windows endlines are all acceptable ways of ending lines.
2. Leading and trailing whitespace on each line is ignored. The remaining, non-empty lines are compared pairwise, using rules 1 and 3.
3. Two floating point numbers are considered equal if their absolute or relative difference is smaller than 1e-6, unless the problem statement says otherwise. This does not apply to integers. Two integers are considered equal only when they are exactly equal.

Source Code Submission Rules

You must upload all source code used to solve each input set as part of the submission of your solution. You cannot submit your source code files after the contest. At the end of the contest, any user can view all of the source code submitted. Both the administrators and other contestants should be able to reproduce your output using your source code.

Deliberately obfuscated source code and empty source code files are not allowed. Facebook reserves the right to disqualify any submissions that we believe do not comply with the rules.

After a round, if Facebook discovers that someone submitted source code that doesn’t match the submitted output (including if you tell us that your source code doesn’t match), Facebook judges will look at that code, look at other code submitted by that user, and determine whether a discrepancy exists. If a discrepancy does exist we will determine whether it is a trivial discrepancy, or a non-trivial discrepancy. If there is no discrepancy, nothing happens. If there is a trivial discrepancy, the contestant will receive five penalty minutes but will keep his or her point for that problem. If there is a non-trivial discrepancy, the contestant will lose credit for that problem.

File Type for Source Code
You must submit plain text or zipped plain text for the source files. The maximum file size that you can upload is 100kB. You can upload multiple files, or you can upload a zipped source code file as long as the contents do not exceed 1MB.

Solving Problems by Hand
If you solve a problem either fully or partly by hand, please submit a text file explaining that you solved the problem by hand. We reserve the right to disqualify any submissions that we believe do not comply with the rules.

Solving problems using methods other than a programming language
If you use specific software to solve a problem, specify this in the file. That software is held to the same restrictions as compilers and interpreters as described above. Also, please provide any input scripts you wrote for the software used (e.g., mathematical software scripts, spreadsheets, etc.).

The program does not necessarily need to produce the output automatically, so it can be interactive. If you wrote an interactive command line script, you should submit all commands used to solve the problem, e.g. a linux command line with awk, Hugs commands, Octave interpreter commands, shell commands, etc.

Solving problems using several programs
If you used several programs to solve a problem, even user-assisted programs, please submit all of the programs.

Solving problems using standard and non-standard libraries
You may use standard libraries, such as Boost, and other open source libraries. If you use a publicly available library, you may submit a link to the library’s website rather than including the contents of the library in your source code submission.

You also may use code from non-standard libraries, such as coding libraries from your school’s ACM ICPC team, as long as you have a license to use them. You will need to upload all code used in solving each input/output set, whether you are using standard or non-standard libraries. If the source code and the zipped version of the library are larger than 1MB, you may provide a link to the library as long as the library is accessible after the contest.

Pearl Harbor Tribute: Thanks to our Armed Forces!

Here at Revive Media Services we fully support and desire to honor our men and women that lay down their lives for our country. We believe that their efforts continue to promote and provide the freedoms that we have and many of us take for granted every day. Being a local Fort Walton Beach, FL business, some of us ex-military, and many of our friends and family currently serving we wanted to take a moment to thank our men and women of the United States Armed Forces.

Take a look below at this nice little tribute to the men and women who gave up their lives at Pearl Harbor on December 7th, 1941:
