smtp-delay plug-in for qmail

by camel
smtp-delay is an add-on/plug-in intended for use with qmail. It was written primarily to add banner delays and antipipelining to qmail. These two features are known to be able to block certain types of spam and virus mail sent through non-rfc-compliant SMTP engines. When I looked around for programs to add this functionality to qmail, I found only one such program, and didn't like the way it was done. BTW...I have the same objections to the way its done in sendmail 8.13.x. Since banner delays (the server pausing for some time before issuing an SMTP banner) cause every SMTP connection to take longer, I thought it would be a good idea to somehow exempt "legitimate" mail servers...or at least not subject them to long banner delays. So I decided to tune the banner delay time based on the connecting IP's reverse DNS. IPs with no rDNS get treated the worst (longest banner delay). IPs with rDNS matching a regex intended to detect dynamic/end-user IPs get a moderate delay. All other IPs get a very short banner delay...just long enough to see if they immediately pipeline (send SMTP commands before the banner's been sent). The original intent for smtp-delay was that it should be run before rblsmtpd, and simply set the RBLSMTPD environment variable if applicable, letting rblsmtpd issue the 4xx response. Pretty early on, I realized smtp-delay should be able to run standalone (without dependence on rblsmtpd to do its talking) and issue a 4xx response on its own. Lately, the spam load against our mail cluster has gotten so bad that I've started running smtp-delay after rblsmtpd, based on the idea that there's no point waiting out a long banner delay holding an open socket to an IP we have no intention of accepting mail from anyway. This reduced our concurrency by about 20%.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch | HowtoForge - Linux Howtos and Tutorials

by camel & 1 other (via)
This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.

Construction Bois - Concours 2006 - Neoconstruction Bois

by sbrothier & 1 other
www.neomenuiserie.fr La conception d'une maison induit la rencontre de deux volontés :celle de l'architecte et celle des futurs habitants. La qualité dépend directement de la dynamique de leurs échanges : les besoins, les envies d'une part, les moyens techniques de l'autre. Dans la perspective de ce concours, la conception de la maison se fait d'une manière exclusivement théorique, tel dans un laboratoire de recherche sur le thème de "vivre mieux", dans un soucis de respect environnemental. Le parti écologique est signifiant par le choix du mode de la construction bois ( montage à sec rapide, matériau sain, recyclable peu énergivore, performant thermiquement...) En réaction à la banalisation de la construction pavillonaire, l'hypothèse de travail avancée est de proposer un système qui consiste en l'assemblage d'éléments standardisé simples, un vocabulaire basique qui puisse intégrer la diversité et l'unicité de chaque maison. Le concept développé ici est un concept de souplesse et de fluidité, un concept origamique. Pour répondre à l'adaptabilité des besoins qui varient d'un âge à l'autre. Pour répondre aussi à l'adaptabilité des besoins thermiques, fluctuant selon les saisons. Les maisons proposées sont des maisons "vivantes" en interaction avec leur environnement. Car chaque maison est unique, comme ses propriétaires, par son adaptation contextuelle sur son terrain (architecture passive par l'optimisation des énergies, vues, vents, etc...)

Notes on Design » Blog Archive » Sustainable Typography

by sbrothier & 1 other
The concept of “green” typography may seem ridiculous to non-type-nerds and, yes OK, perhaps typography can’t conquer climate change, but it can certainly help communicate it! With these thoughts in mind, I thought it would be interesting to share some recent examples I’ve found of contemporary typography that truly redefine those terrifying visions of green (and tree-shaped) logos!

scalr - Google Code

by camel & 3 others
Scalr is a fully redundant, self-curing and self-scaling hosting environment utilizing Amazon's EC2. It allows you to create server farms through a web-based interface using prebuilt AMI's for load balancers (pound or nginx), app servers (apache, others), databases (mysql master-slave, others), and a generic AMI to build on top of. The health of the farm is continuously monitored and maintained. When the Load Average on a type of node goes above a configurable threshold a new node is inserted into the farm to spread the load and the cluster is reconfigured. When a node crashes a new machine of that type is inserted into the farm to replace it. 4 AMI's are provided for load balancers, mysql databases, application servers, and a generic base image to customize. Scalr allows you to further customize each image, bundle the image and use that for future nodes that are inserted into the farm. You can make changes to one machine and use that for a specific type of node. New machines of this type will be brought online to meet current levels and the old machines are terminated one by one. The project is still very young, but we're hoping that by open sourcing it the AWS development community can turn this into a robust hosting platform and give users an alternative to the current fee based services available.

L'Encyclopédie de L'Agora: Henry David Thoreau

by alexandre & 1 other
"Si Thoreau est à sa manière un ermite-vagabond, sa démarche apparaît avant tout fondée sur un constat d’ordre social : celui de la servilité d’un genre de vie centré sur le travail et un économisme utilitaire désenchanteur de monde. Gagner sa vie en échinant son existence. Thoreau l’ascète réhabilite quant à lui le principe d’une joie contemplative, liée à un usage poétique de l’espace.

Walden ou la vie dans les bois - Wikisource

L’opinion publique est un faible tyran comparé à nos propres opinions privées. Ce qu’un homme pense de lui-même, voilà ce qui détermine, ou plutôt montre, son destin.
