prime database project / News: Recent posts

i am back.after 3 year.
primedb project will rebuild.
old code are not stable and good at structure.
today i had rewrited the init_database program.
someday late i will release the 0.6rc1 version.

primedb is a project that attempt to generation prime numbers fast and saving them to a database(Mysql or else) for prime research: finding large number of prime,prime factorization,Goldbach's conjecture,twin prime conjecture...

This version improve a lot and fix almost all bugs.
now it's faster and more stable now.

primedb currently only can calculate primes.
I'm going to do some real things now!
primedb's next goal is to build a lot of utility.
the first one is to check if a num is prime or not.
and then i will release primedb v0.6.0.

After series of test primedb v0.5.0 released at last!
This version rewrite a great deal kernel code of primedb to OOP at the beginning.
But quickly I found that use OOP is so slowly.primedb v0.5.0 Alpha1's speed is slowly then v0.4.x.I didn't want to give up OOP.So I write Alpha1~Alpha5 to improve primedb's speed.

Now primedb v0.5.0 only contain 2 perl modules.

And good news is primedb v0.5.0 is high speed than old version!

Although time to release primedb v0.5.0 is still a long time(about one week),I have a idea to improve primedb.

Present version of primedb(0.4.x) waste to many memory to work fast,I have find a way to saving memory,it will consume less then 1/10 of memory of currently version of primedb.

But I still have to fixed and improved some details so I will release 0.4.4 0.4.5...first.

simple_prime_database contain simply prime database create by primedb && mysql.database dump by mysqldump.

in the archive file have README file to teach how to restore the database.

This release fix a lot of bugs and have do some files adjusted.besides I have add README,INSTALL,ChangLog,LICENSE,VERSION files in this released.so it's more friendly to end user.
