  • One Thing Well | Let’s Encrypt – Let’s Encrypt is now in public beta and offers a command line tool that makes the process of getting and renewing certificates easy, but you have to run it as root, and it’s designed to rewrite your web server’s configuration files. Here’s a selection of alternative tools and clients:
  • Tsung – It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware …). Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications. [ via http://onethingwell.org/post/134852940551/tsung ]
  • Internet Redundancy with ASA SLA and IPSec – PacketU – I’ve seen a lot of examples of redundant Internet connections that use SLA to track a primary connection. The logic is that the primary Internet connection is constantly being validated by pinging something on that ISP’s network and routing floats over to a secondary service provider in the event of a failure. I was recently challenged with how this interacted with IPSec. As a result I built out this configuration and performed some fairly extensive testing.

Upgrades can be performed, backups can be generated, new posts can be published and most of the regular admin actions can be performed with a set of commands. In this tutorial we will explain how to use the WP command line interface in order to complete regular administrative tasks like upgrades, database backup creation, plugins and themes installations and removals, publishing and deleting posts, changing site's URL settings and getting help on chosen commands. Note that WP-Cli requires an SSH access.

  • How to write udev rules – Since the adoption of Kernel 2.6, Linux has used the udev system to handle devices such as USB connected peripherals. If you want to change the behavior when you plug something into a USB port, this section is for you. As an example, we will use a USB thumb drive but these methods should translate to any device handled by udev. As a goal for this exercise we decided to create a symlink and execute a script when a specific thumb drive was loaded.
  • Persistent iSCSI LUN Device Name – jablonskis – […] I spent a bit of time figuring out how to get this achieved, so thought it is worth noting for the future reference. I will try to make this quick assuming you have knowledge about iSCSI software initiators in Linux[…]

  • NSA-proof your e-mail in 2 hours | Sealed Abstract – You may be concerned that the NSA is reading your e-mail. Is there really anything you can do about it though? After all, you don’t really want to move off of GMail / Google Apps. And no place you would host is any better. Except, you know, hosting it yourself. The way that e-mail was originally designed to work. We’ve all just forgotten because, you know, webapps-n-stuff. It’s a lot of work, mkay, and I’m a lazy software developer.

  • The Twelve-Factor App – In the modern era, software is commonly delivered as a service: called web apps, or software-as-a-service. The twelve-factor app is a methodology for building software-as-a-service apps that: Use declarative formats for setup automation, to minimize time and cost for new developers joining the project; Have a clean contract with the underlying operating system, offering maximum portability between execution environments; Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration; Minimize divergence between development and production, enabling continuous deployment for maximum agility; And can scale up without significant changes to tooling, architecture, or development practices. The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc).

  • ii.com · Procmail Quick Start: An introduction to email filtering with a focus on procmail by Nancy McGough – rocmail is free/libre open-source software that is both a mail processor and a mail delivery agent (MDA). It can be used by either a system administrator or a user to automatically process and deliver incoming mail messages. It can also be used to re-process and re-deliver messages that are already in a mailbox. This Procmail tutorial is aimed at regular users, not system administrators.
  • agentile/S3-Media-Storage – Store media library contents onto S3 without cron jobs. This is more ideal for multiple web server environments. Because of the logic surrounding WordPress media uploads and the availability/order in which hooks/actions surrounding media uploading, we cannot get away from temporarily storing the uploaded file in the uploads directory. What this plugin will be able to do is to take that uploaded file, move it to S3, and delete the local uploaded file all in the same request.
  • Using AWS S3 with WordPress for Media Asset Storage | Ian Massingham’s Blog – As you know I recently migrated this blog from Google’s Blogger service to a self hosted WordPress installation running on the AWS Cloud. Since then, I have been working on improving the resilience and scalability of the new platform by using a few additional AWS features. One of the things I have changed is to move media assets, such as images, from the EC2 instance that runs the WordPress application to be externally hosted on AWS S3.

  • Ralentir le débit de postfix pour wanadoo/orange – Le blog de Michauko – Si vous avez un serveur d’envoi de mails (je ne parle pas d’être un spammeur) et beaucoup d’abonnés chez Wanadoo et Orange, vous risquez fort le rejet temporaire de votre serveur si le débit d’envoi est trop fort. C’est ce qui m’est arrivé et hop, 5000 mails entassés dans la file de postfix.
  • smtp-in.orange.fr refused to talk to me: postfix solution | floriancrouzat.net – Orange sadly limits inbound connexion to it’s MX to 1 connexion per IP, which is a total pain in the ass when you try to deliver newsletter, or manage a MTA. Here is a sample log from their MX: Jul 4 10:42:42 smtp.example.com postfix/smtp[32347]: 0123456789: host smtp-in.orange.fr[193.252.22.65] refused to talk to me: 421 mwinf5c34 ME Trop de connexions, veuillez verifier votre configuration. Too many connections, slow down. OFR004_104 [104] However, since they won’t change anything, we have to take mesures, here’s what you can do if you run postfix: you have to set a per-destination concurrency limit.
  • Aral Balkan: Historical Archive — How to revert (roll back) to a previous revision with Subversion – Here, then, is a very simple, plain English explanation of how to revert to a previous version of your application in Subversion, to help anyone who may be starting out with it and is lost.

  • Tyblog | Yet Another Vim Setup – Vim is an excellent text editor. I’ve used it for many years and like most vim users, have collected a fairly large collection of settings in my .vimrc and learned how to grok my vim usage effectively through a lot of trial and error. To that end, I’ve tried to assemble a useful overview of my experience with vim.
