Intro At Infoxchange we use XenServer as our Virtualisation of choice. There are many reasons for this including: Open Source. Offers greater performance than VMware. Affordability (it’s free unless you purchase support). Proven backend Xen is very reliable. Reliable cross-host migrations of VMs. The XenCentre client, (although having to run in a Windows VM) is quick and simple to use. Upgrades and patches have proven to be more reliable..

Further to my earlier post on XenServer storage performance with regards to directly attaching storage from the host, I have been analysing the performance of various SSD storage options. I have attached a HP DS2220sb storage blade to an existing server blade and compared performance with 4 and 6 SSD RAID-10 to our existing iSCSI SANs. While the P420i RAID controller in the DS2220sb is clearly saturated and unable to provide throughput ..

Introduction HackerEarth uses django framework at its heart. We use two third party django packages for the purpose of user authentication and session management: django-allauth : Provides pre-built modules for email-based as well as all popular social authentication mechanisms. django-redis-sessions : Allows storage of user session data in redis (a memory based data store that writes on disk) for fast retrieval. We used MySQL earlier ....

Rust Sydney had its first event last Monday! The first Rust gathering I know of in Sydney, in Australia, or in the whole southern hemisphere. I had fun meeting all sorts of people interested in Rust: some who’d dived in deep already, some who’d only recently started playing with it, and some who’d been following for a while but had unfortunately not got time to actually use it (hopefully soon!). Thanks to everyone who came and, to ....

Last Saturday we had the Short North gallery hop . Hundreds of people came through our gallery to see art. The guys helped me set up the Oculus and a projector on the wall. Sometimes I had to go out and pull people in, but most of the time, there was a line. My favorite customer by far was this kid: He jumped right in and played like a pro. The mother (recording video) was super supportive and excited.

Frequently while coding I need to know the internal and external IP address of my development machine. For example, when your machine is serving a website from a locally running web server, the internal IP address can be used to test the site from a smartphone browser connected to the same network. Likewise, the external IP address is useful when you want to make a local web server publicly accessible or when you need to whitelist your IP a..

in which we explore lazy sequences and common functional idioms in Clojure via the example of looking for (nearly) coincident clusters of times in a series. A fundamental technical problem in experimental particle physics is how to distinguish the signatures of particles from instrumental noise.

I ran into the need to access the internet from a VirtualBox VM via host-only networking. Of course, you’re saying “There’s a better way to do that!” And of course, I agree: with no other considerations, the best way to do this is to simply add another NIC to the VM configured as NAT instead of host-only. However, I’m trying to test out some new networking ideas for my OpenStack Network node, and it doesn’t have a NIC configured with NAT.

this post is about an all-italian open source release, so it’s going to be in italian FatturaElettronicaPA è un nuovo progetto open source che ho rilasciato qualche giorno fa assieme alla mia azienda . Si tratta di una libreria C# che permette di leggere, scrivere e convalidare le Fatture Elettroniche aderenti alle specifiche del sistema di interscambio della Pubblica Amministrazione.

Last time we saw a number of properties of graphs, such as connectivity, where the probability that an Erdős–Rényi random graph $ G(n,p)$ satisfies the property is asymptotically either zero or one. And this zero or one depends on whether the parameter $ p$ is above or below a universal threshold (that depends only on $ n$ and the property in question). To remind the reader, the Erdős–Rényi random “graph” $ G(n,p)$ is a distribution over gr..

You might want to write code that can tell how many iterations have passed since some action occurred. Alternatively, you might want to know if it’s the first time a machine has run Puppet . To do these types of things, you might wish to have a monotonically increasing counter in your Puppet manifest. Since one did not exist, I set out to build one! The code : If you just want to try the code, and skip the ramble, you can include c..
