using Git as a database back-end
by Stanislav Sinyagin 03 May '17

03 May '17

hi all, I'm preparing a new release of Torrus software, and it will replace BerkeleyDB back-end with Git. It appears that libgit2 provides a new, a bit tricky in learning, but very efficient object storage, and change tracking is available out of the box. In general, you can read and write your data objects directly in the Git repository, without the need of checking in and out the files in your filesystem. Also the objects can be automatically compacted, and that allows storing millions of objects without too much load on the filesystem resources and inode count. Of course it's not a fully blown database, and not even something like MongoDB, but it really is usable and convenient for document storage systems. Here are few working examples of using libgit2 (particularly, with its Perl binding, but it's similar in other programming languages): https://github.com/ssinyagin/git_raw_excercise Also, the new Torrus branch, and changes document: https://github.com/ssinyagin/torrus-newfeatures/tree/v3 https://github.com/ssinyagin/torrus-newfeatures/blob/v3/src/doc/devdoc/v3_c… If there's interest in the topic, I will prepare a presentation for the next Swinog meeting. -- Stanislav Sinyagin Senior Consultant, CCIE #5478 ssinyagin(a)k-open.com +41 79 407 0224

Looking for person responsible for *@mms.sunrise.ch
by Markus Wild 27 Feb '17

27 Feb '17

Sorry to spam the list for this, but I was not able to find anything close to a technical support email contact on their web page... To avoid many round trip mails, here's the problem: we get incoming mails with senders like <+4176...(a)mms.sunrise.ch>. But: mms.sunrise.ch. 3600 IN MX 10 mm3.sunrise.ch. Host mm3.sunrise.ch not found: 3(NXDOMAIN) So, those sender addresses are invalid, and get rejected on our mail servers. Might want to fix your DNS.. Cheers, Markus

Hello All Anyone else running bind9 and seeing a lot of request with permuted case in the requested resource, which I fear causes bind9 to cache each reply individually leading to memory exhaustion? -Benoît-
