  • Migrating from VMware to an open-source private cloud in financial services | Ubuntu

    This is part one of a two part blog series on open source based private cloud for financial services. This blog describes the need for a cost-effective private cloud to execute a successful hybrid cloud strategy. It also shares a comparison between proprietary and open source based private cloud platforms.

To drive business agility, financial institutions are on a journey to fundamentally reshape their IT infrastructure. As their IT estates grow and become more complex, financial institutions are increasingly facing the challenge to optimise their infrastructure spend. Many financial institutions are adopting scalable and agile cloud infrastructure guided by a hybrid multi-cloud strategy.

  • How to Record Audio in Ubuntu and other Linux Distributions

    How to record audio in Ubuntu and other Linux distributions? If you want to record a voice over through the microphone of your computer, you can use GNOME Sound recorder or Audacity. Using GNOME Sound Recorder is easy but it lacks features. Audacity could be overwhelming initially but it has plenty of features for professional level recording. However, I am not going into that detail in this tutorial. GNOME Sound Recorder works with the microphone. There is another tool called Audio recorder and you can use it to record streaming music (from Sptify, YouTube, internet radio, Skype and most other sources) apart from microphone input.

  • How I wish I could organize my thoughts

    I keep a pen & notebook on my desk, which I make liberal use of to jot down my thoughts. It works pretty well: ad-hoc todo lists, notes on problems I’m working on, tables, flowcharts, etc. It has some limitations, though. Sharing anything out of my notebook online is an awful pain in the ass. I can’t draw a straight line to save my life, so tables and flowcharts are a challenge. No edits, either, so lots of crossed-out words and redrawn or rewritten pages. And of course, my handwriting sucks and I can type much more efficiently than I can write. I wish this was a digital medium, but there are not any applications available which can support the note-taking paradigm that I wish I could have. What would that look like? [...] Other objects would include flowcharts, tables, images, hand-written text and drawings, and so on. These objects can be placed free form on the grid, or embedded in a page, or moved between each mode. The user input paradigm should embrace as many modes of input as the user wants to provide. Mouse and keyboard: middle click to pan, scroll to zoom in or out, left click and drag to move objects around, shift+click to select objects, etc. A multi-point trackpad should support pinch to zoom, two finger pan, etc. Touch support is fairly obvious. Drawing tablet support is also important: the user should be able to use one to draw and write free-form. I’d love to be able to make flowcharts by drawing boxes and arrows and having the software recognize them and align them to the grid as first-class vector objects. Some drawing tablets support trackpad and touch-screen-like features as well — so all of those interaction options should just werk.

  • Type support: getting started with syslog-ng 4.0 - Blog - syslog-ng Community - syslog-ng Community

    Version 4.0 of syslog-ng is right around the corner. It hasn’tyet been released; however, you can already try some of its features. The largest and most interesting change is type support. Right now, name-value pairs within syslog-ng are represented as text, even if the PatternDB or JSON parsers could see the actual type of the incoming data. This does not change, but starting with 4.0, syslog-ng will keep the type information, and use it correctly on the destination side. This makes your life easier, for example when you store numbers to Elasticsearch or to other type-aware storage. From this blog, you can learn how type support makes your life easier and helps you to give it a testdrive on your own hosts.

  • Why I joined Mozilla’s Board of Directors

    I first started working with digitalization and the internet when I became CEO of Scandinavia Online in 1998. It was the leading online service in the Nordics and we were pioneers and idealists. I learnt a lot from that experience: the endless opportunities, the tricky business models and the extreme ups and downs in hypes and busts of evaluation. I also remember Mozilla during that time as a beacon of competence and idealism, as well as a champion for the open internet as a force for good.
