- Deis | Your Paas. Your Rules. – Deis (pronounced DAY-iss) is an open source PaaS that makes it easy to deploy and manage applications on your own servers. Deis builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow.
- Speed up WordPress on DreamHost with OPcache
Installing OPcache can improve your site’s performance by decreasing the php execution process when a script is requested. DreamHost permits a user to log into the server through secure shell with user level permissions. Since user level permissions cannot install software, the module will need to be manually compiled.
- Reduce TIME_WAIT socket connections | Linux BrigadeReduce TIME_WAIT socket connections in Apache/Linux
Some time in your life you’ll run across an Apache server that always has tons of TIME_WAIT connections just seeming to hang out. While these don’t take up as many resources as an ESTABLISHED connection, why keep them around so long? This short article will show you how to identify how many you have, and how to tell your server to reduce them, reuse and recycle them (see, recycling IS a good thing).
- Analyzing Apache Log Files < System | The Art of Web
There are many different packages that allow you to generate reports on who’s visiting your site and what they’re doing. The most popular at this time appear to be “Analog”, “The Webalizer” and “AWStats” which are installed by default on many shared servers. While such programs generate attractive reports, they only scratch the surface of what the log files can tell you. In this section we look at ways you can delve more deeply – focussing on the use of simple command line tools, particularly grep, awk and sed.

- Alfresco: some useful database queries – Blog dbi services – In my previous post, I talked about the Lifecycle of Alfresco Nodes. You may have noticed that I tried to insert in my explanations some elements that are specific to databases (tables, fields, aso…). These elements are quite essential to prepare a post like this one: more database oriented. I already explained what exactly are the consequences on the database side when a node is removed and I will try in this post to share some useful queries regarding these points but not only! For this post, I used my local Alfresco Community 4.2.c installation with a PostgreSQL database. For your information, it just take 30 minutes to get this test environment ready with the Alfresco’s installer (Windows, Mac or Unix). Of course, use the Database only for your daily administration work is certainly not the best idea but in some cases, it can really be faster and easier to just run some SQL commands at the DB level…

- Shrinkpdf – A simple wrapper around Ghostscript to shrink PDFs (as in reduce filesize) under Linux. Inspired by some code I found in an OpenOffice Python script (I think). The script feeds a PDF through Ghostscript, which performs lossy recompression by such methods as downsampling the images to 72dpi. The result should be (but not always is) a much smaller file

- How to create a read only user in Cisco devices | Cisco & Juniper Networking Note Book
Here is the thing, can you believe there is no straight forward way to configure a read only user in Cisco devices. If you know any way to do it please correct me here.

- Painless Immutable Infrastructure with Ansible and AWS | Radify Blog – […] In our blog posts Reducing Infrustration and Immutable Demo Nodes, we talk about our approach to immutable infrastructure and the benefits we have seen from employing this approach. In this article, we explore a practical project example so you can get up and running with immutable infrastructure in less than an hour! […]

- Provisioning EC2 Hosts with Ansible | Allan Denot – Looking to build EC2 hosts with more consistency? Using Ansible you can easily provision EC2 hosts and put some logic on it to adjust EC2 parameters based on the type of host you are building.
The easiest way to start is to create a playbook calling the ec2 module with the parameters you want to pass to AWS to create your host. In this post I will show a little more scalable way to do this, where the parameters are variables and you can easily have multiple types of hosts sharing the same playbook and role.

- VMware: Add PortGroup to all hosts in cluster with PowerCLI – […]
Today we configured a new VLAN on the physical switches, now we need to configure a portgroup with vlan id on multiple ESX hosts in our cluster. To do this by hand it will cost 3 minutes per host, to script this.. you configure this in 10 seconds![…]
- Creating Active Directory Accounts – Microsoft stores a quoted password in little endian UTF16 base64 encoded.
- LVM Loopback HOW-TO | Anthony’s Blog – This is a simple tutorial on setting up LVM on loopback devices, I’ve used it a few times for creating dynamic virtual disks; it came in particularly handy when archiving NEXRAD radar data for my radarwatchd project – using up all your inodes on several hundreds of thousands of 15Kb files doesn’t sound like my idea of fun. Creating a virtual volume with reiserfs was a particularly handy solution in this case.
- Retroshare – Retroshare creates encrypted connections to your friends. Nobody can spy on you. Retroshare is completely decentralized. This means there are no central servers. It is entirely Open-Source and free. There are no costs, no ads and no Terms of Service.
