Integrated banner for WikiProject Computer science
I have made a proposal for a integrated banner for the project  here . I invite you for your valuable comments in the discussion. You are receiving this note as you are a member of the project. Thanks --  Tinu  Cherian  - 09:43, 3 August 2008 (UTC)

Hi

Are you still an active user in the Robotics Project ?

If so can you please read this message Wikipedia_talk:WikiProject_Robotics reply at Category_talk:WikiProject_Robotics_participants

Asian 10,000 Challenge invite
Hi. The WikiProject Asia/The 10,000 Challenge has recently started, based on the UK/Ireland The 10,000 Challenge and WikiProject Africa/The 10,000 Challenge. The idea is not to record every minor edit, but to create a momentum to motivate editors to produce good content improvements and creations and inspire people to work on more countries than they might otherwise work on. There's also the possibility of establishing smaller country or regional challenges for places like South East Asia, Japan/China or India etc, much like The 1000 Challenge (Nordic). For this to really work we need diversity and exciting content and editors from a broad range of countries regularly contributing. At some stage we hope to run some contests to benefit Asian content, a destubathon perhaps, aimed at reducing the stub count would be a good place to start, based on the current WikiProject Africa/The Africa Destubathon which has produced near 200 articles in just three days. If you would like to see this happening for Asia, and see potential in this attracting more interest and editors for the country/countries you work on please sign up and being contributing to the challenge! This is a way we can target every country of Asia, and steadily vastly improve the encyclopedia. We need numbers to make this work so consider signing up as a participant! Thank you. -- Ser Amantio di Nicolao Che dicono a Signa?Lo dicono a Signa. 01:25, 20 October 2016 (UTC)

Latin American 10,000 Challenge invite
Hi. The WikiProject Latin America/The 10,000 Challenge ‎ has recently started, based on the UK/Ireland The 10,000 Challenge and WikiProject Africa/The 10,000 Challenge. The idea is not to record every minor edit, but to create a momentum to motivate editors to produce good content improvements and creations and inspire people to work on more countries than they might otherwise work on. There's also the possibility of establishing smaller country or regional challenges for places like Brazil, Mexico, Peru and Argentina etc, much like The 1000 Challenge (Nordic). For this to really work we need diversity and exciting content and editors from a broad range of countries regularly contributing. At some stage we hope to run some contests to benefit Latin American content, a destubathon perhaps, aimed at reducing the stub count would be a good place to start, based on the current WikiProject Africa/The Africa Destubathon. If you would like to see this happening for Latin America, and see potential in this attracting more interest and editors for the country/countries you work on please sign up and being contributing to the challenge!

Women in Red World Contest
Hi. We're into the last five days of the Women in Red World Contest. There's a new bonus prize of $200 worth of books of your choice to win for creating the most new women biographies between 0:00 on the 26th and 23:59 on 30th November. If you've been contributing to the contest, thank you for your support, we've produced over 2000 articles. If you haven't contributed yet, we would appreciate you taking the time to add entries to our articles achievements list by the end of the month. Thank you, and if participating, good luck with the finale!

Both Tonelli-Shanks and Cipolla's modular square root algorithms can handle powers of prime modula (not just primes)
I looked up Dickson's History of Numbers vol 1 p215(Tonelli) and p218(Cipolla) and Dickson clearly shows that both modular square root algorithms can handle powers of prime modula (whereas the Wiki articles say they can only do prime modula).

I've updated the TALK pages of both articles with the relevant Dickson math, along with numeric runthroughs with Mathematica code.

However, I am not a professional mathematician so I hesitate to update the articles.

Perhaps yourself, or someone else in the Computer science field could update the relevant articles with this information from Dickson.

The articles in question are:


 * Tonelli–Shanks algorithm


 * Cipolla's algorithm

 * I am not an expert in the subject (my areas are Complexity Theory, Algorithm Design and Analysis, and Computational Geometry), but I will try to look at it and let you know. Carlos Alegría (talk) 21:16, 14 February 2018 (UTC)


 * Have you had any luck with the articles. I can ask someone else in the computer science group to do it, if you don't feel you are qualified for it. Endo999 (talk) 03:16, 20 February 2018 (UTC)


 * I overview the articles. It is not that I am not qualified but it is not my are of expertise. It will definitely take me more time to study what I need to give you an answer. If you cannot wait for my answer, please go ahead and ask someone else.Carlos Alegría (talk) 18:15, 20 February 2018 (UTC)


 * Thanks for replying. You're the only one who has so far.  Please go ahead if you wish to do the articles, but I'll ask a few other people as well.  I'm not a professional mathematician so I wasn't planning on doing it myself, but I might have to if nobody else will.  Endo999 (talk) 19:24, 20 February 2018 (UTC)
