24 hours into the Challenge and Cupid and the tiger have been very successful in their hunt for primes - already snagging over 35 "Top 5000" primes. 48 hours remain so it's not too late to jump in the fray and see if you too can capture a prime. For more information, please see this forum thread.
已经发现了35个大质数（这些质数在最大的质数中能排到前5000）。

Only 24 hours remain till the start of the 2010 Challenge Series and Valentine's Day in the West and the Year of the Tiger in the East. Cupid is flying overhead while the tiger circles below. Please come join us in an East & West fearless attack on Proth Primes.

A 3 day (14-17 Feb) Challenge is being offered on PrimeGrid's Proth Prime Search (LLR). Application builds are available for Mac, Linux, and Windows. For more information, please see this forum thread.

We are kicking off the 2010 Challenge Series with the Year of the Tiger Challenge which just so happens to coincide with Valentine's Day in the West. The Tiger is the third sign in the Chinese Zodiac cycle, and it is a sign of fearlessness. It is considered incredibly brave, evidenced by its willingness to engage in battle. So whether it's your love of Tigers or love of primes, please come join us in an East & West fearless attack on Proth Primes.

The Year of the Tiger Challenge
Less than 4 hours remain. The hunt has been very successful for Cupid and the Tiger. Just as PrimeGrid's validator is struggling to keep up with the Challenge, the Prime Pages' validator is struggling to keep up with the prime submissions. :D Over 75 "Top 5000" primes have been found so far!!!There's still time to join the hunt. For more information, please see this forum thread.

First ever AP26 Found!
2010-04-12 23:55 UTC
The search is over. A World Record AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Benoãt Perichon [AF>HFR>RR] Jim PROFIT) of France. He is a member of the L'Alliance Francophone team.
The AP26 progression is written as 43142746595714191+23681770*23#*n for n=0..25. It was found by a PS3 running Linux. For more details on this find, please see this forum post.
Congratulations to everyone who participated in the AP26 Search. It has been a very challenging and rewarding project. Also, a special thanks to all the programmers who ported AP26 making it the most accessible project at PrimeGrid.
Note: there will be no more work once the queue is empty, so we would like to ask people not running for the badges to stop running AP26 subproject and give a chance for others to reach their final levels.

发现了第一个AP26！

AP26的搜索结束了。我们找到了首个AP26（由26个质数组成的等差数列）。发现者是法国的Benoãt Perichon （[AF>HFR>RR] Jim PROFIT）。他是 L'Alliance Francophone 队的成员。
找到的这个AP26可以写成43142746595714191+23681770*23#*n， n=0..25，是在一台运行Linux的PS3上发现的。更详细的信息请参见这个论坛帖子。
祝贺每位AP26的参与者！这个项目非常有挑战性，但收获也不少。同时特别要感谢的还有那些将AP26移植到各个平台的程序员。正是你们使AP26成为PrimeGrid上支持平台最多的子项目。
注意：不会再在工作队列中加入新的工作包了。希望那些不是跑奖章的同学就不要跑AP26了，让跑奖章的同学有机会把他们的奖章跑出来。

PrimeGrid 2010秋季筹捐

PrimeGrid这个项目没有受到任何大学或者商业实体的赞助。事实上，全部基金来自社区，大部分是通过捐款页、小部分通过网站上的Google广告筹得。之前的月份这些捐款足够网站的一切运行开支，但是近几个月来情况恶化，光是支付服务器的开销我们不得不动用了应急基金中的一大部分。

讨钱嘴难开，但现在我们别无他路。我们所剩的只够让服务器再运行两个月。之后，我们要么只能将服务器关闭，要么就得把服务器性能大大减弱，变成一件让人惋惜的事，因为PrimeGrid建立时的身份是质数社群中的重要力量，又已然获得了成员贡献无数的支持。

所以我们现在推出PrimeGrid 2010秋季筹捐。我们的目标是4000欧元，这个数目足够我们的项目再持续一整年，并且恢复应急基金的空缺。

无论捐款或多或少，请一定帮忙！尽管PayPal致使最低限额是欧元2元（注：2 euro大概等价于18元人民币。）。（如果你愿意银行转帐，我们在荷兰、德国、波兰、立陶宛有银行户头，请给PrimeGrid的负责人发一条私人消息。）
为了让这个项目继续进行下去，请访问捐款页面，选择秋季筹捐项目，捐出你感觉适当的数目。我们提前向您致以感谢。

2010年8月17日更新：感谢各位已经捐款的算友，我们已经得到了预期的15%。我们也开放了德国银行户头的直接转帐。
2010年8月18日更新：我们已经得到了接近30%的预期！谢谢您的支持！我们再开放了波兰的银行户头的直接转帐。
