Another year, another week. Here we go again. Extremely busy week and announcements of companies acquiring other companies all over the place. Bloggers joining vendors or just changing jobroles. Crazy week, and same goes for the quality of the articles this week.
Steve Kaplan - Microsoft’s attempt to commoditize virtualization Despite these many unique attributes, VMware's most compelling differentiator may be its astounding reliability. Unlike Hyper-V, it offers data center stability, performance and security that is independent from the bloat, reliability and patching issues of a general-purpose operating system. Even Redmond Magazine, "The Independent Voice of the Microsoft IT Community" gave its 2008 Editors Choice award for the most reliable IT technology to VMware ESX (the IBM mainframe came in #2).
Duncan Epping - esxtop values/thresholds! I am a huge fan of esxtop! I read a couple of pages of the esxtop bible every day before I go to bed. Something I however am always struggling with is the “thresholds” of specific metrics. I fully understand that it is not black/white, performance is the perception of a user. There must be a certain threshold however. For instance it must be safe to say that when %RDY constantly exceeds the value of 20 it is very likely that the VM responds sluggish. I want to use this article to “define” these thresholds, but I need your help. There are many people reading these articles, together we must know at least a dozen metrics lets collect and document them with possible causes if known.
Martin MacLeod - Follow the moon, data center virtualization – a short essay We introduced the world to server virtualization where instead of having a server per application, we could buy a server with a bit more memory, a bit more storage and have that ‘cut up’ and shared amongst the business units. It worked on the whole very well, but IT was still a bit confused and still is in many ways about how we charge for it and how we ‘make a profit’ for their cost center, you see we can only absorb so much before someone has to pay for the underlying infrastructure the 400TB of storage, the 32GB of RAM in each server, and compare that with the 1u special that might be good enough for a given application, keeping the per unit virtual machine cost competitive could be a challenge if we didn’t look at the way we billed for capacity, for delivering IT service.
Gabrie van Zanten - Putting your storage to the test – Part 2 NFS on Iomega IX4-200D I was surprised to see so much difference in performance, I had expected some difference, but no difference as big as this. Looking at the data of the first “Super ATTO Clone pattern” test I ran, I can see the biggest difference between NFS and iSCSI being the short peak in read speed where iSCSI remained stable after reaching its peak performance at 41 MB/sec. NFS peaked to 110 MB/sec testing block sizes from 32K to 512K and dropped in speed to 57 MB/sec on blocks of 1M and larger.
Steve Chambers - Four economic variables and approaches to make your VDI solution successful Put yourself in the shoes of a business manager: “Why should I pay Internal IT $250/qtr for a hosted desktop when I can buy physical for less/similar, or use a cloud offering?” The common response by Internal IT to this question is: “You HAVE to buy from us!” (footnote: even if we cost more and are worse). That kind of mandate might seem smart, but it’s a key indicator that Internal IT is losing the battle and has lost the war. If this is an Outsourcer saying this, then the writing is on the wall for them and I can 100% guarantee they are going to have to go through a tender at the end of their contract (expensive for outsourcer).
26.09.2013 The End of the Google Summer of Code The GSoC coding period has ended last Monday. In this blog post, I will summarize what I have done during the summer, to give a general idea of what you can expect from a future version of Nepomuk, if my work is accepted by the Nepomuk maintainers. The source code of the first two projects is available in the steckdenis-gsoc2013 branches of the nepomuk-core and nepomuk-widgets Git repositories. The browser plugin can be found in the scratch/dsteckelmacher/nepomukintegration.git scratch repository. The Nepomuk Query Parser The first part of my GSoC project was to implement a new ...02.04.2009 Milian Wolff (milianw): KDevelop Hack Sprint Huzza! The KDevelop Hack Sprint 09 is now official. Thanks to the huge engagement of Alexander Dymo we will meet from the 19th to 26th April 2009. The meeting will take place at Alexander’s university, the national university of shipbuilding in Odessa, Ukraine. Thanks to the people there responsible for making this sprint possible by providing us with the premises, internet, power etc. Since this is my very first Hack Sprint and considering that I only recently started contributing to KDE in general and KDevelop in particular I am very excited. The topics I will plan to hack on include (...14.07.2010 Mario Fux (unormal): KDE work day 1 - xml and nepomuk I’m sitting in the train from Zurich to Burgdorf (Switzerland) and want to report, dear reader, about my first week of KDE (or atm qt) development. It was not really as I planned it, I did not work a whole day on qt and kde, but several hours during the week. As I told you last week my first week was about an xml indenter. Some years ago when I started to track routes for OpenStreetMap.org my Garmin GPS device spat out bad formatted xml (GPX) files. Bad means here that all of the content was on one line and as I sometimes wanted to extract single tracks me and the dear editor (Kwrite or ...15.01.2009 Aaron Seigo (aseigo): building a community around your F/OSS project Today has turned into another writing day for me. Huzzah! I started going through my list of blog-posts-I've-not-yet-written and decided to punctuate the day with a couple of them. So let's talk a bit about building a community around your F/OSS project.Usual disclaimers apply: this is what works for me, it may not work for you; I could be completely insane and talking about my posterior; I probably am just repeating what other people have said elsewhere; I'm going to be hypocritical in places by giving advice that I don't follow overly well myself. So there.Onwards!Why It MattersIt is not unc...27.01.2010 Troy Unrau: Camp KDE coverage summary Hi guys, I was preparing this summary of blogs and other coverage of Camp KDE to forward to our sponsors to show the activity occurring at the event. I figured I'd share it with the planet, if you folks are interested. If blogging is a measure of productivity, we certainly set the bar high. :) Dot.kde.org Posts (during and around the event only):http://dot.kde.org/2010/01/16/camp-kde-about-starthttp://dot.kde.org/2010/01/17/day-one-camp-kde-2010http://dot.kde.org/2010/01/21/camp-kde-2010-continues-more-talkshttp://dot.kde.org/2010/01/21/camp-kde-day-three-technical-talks-summarieshttp://dot.kd...16.02.2010 Aurelien Gateau: A week in Portland, Oregon I spent the first week of February in Portland, where I attended Canonical Platform Sprint for Ubuntu Lucid. We got some good work done on the DBusMenu front. You can read about it on Jono and Jorge blog posts. 18.05.2008 Michael Pyne (mpyne): Usability in interfaces So on an article on a programming weblog. The topic of the article was a group that decided to make a copy of Funpidgin and was essentially created because the people making the copy feel the Pidgin development team are not listening to the needs of their users. Celeste Lyn Paul, one of the KDE team’s usability designers (the group that tries to make the software we make actually usable by the end user) a comment about the amount of issues that people bring in the name of usability. He then later posted a S5W nuclear reactor plant. This plant was very old by the time I qualified on it (M...01.03.2008 Niels van Mourik (nielsvm): Re-entering the blogosphere Hello there blogosphere, It has been almost one year ago the last time I wrote a entry in this dusty blog. And since then, a lot of things changed in my life and on the web. And one of those is that I got a new, and my first serious job back in June last year. So, back in June ‘07 I started working at the funny called company FOSDEM took place at the free university of Brussels, Belgium. After some bad experiences with hostels the previous years I subscribed to the organised KDE accomodation by Lydia Pintscher (Quassel). Before the event started the FOSDEM people organised the ‘Fri...08.05.2010 Ronny Yabar (ronnyml): First steps with Grantlee and my KDE PIM GSoC project Well, coding officially starts on May 24, now is time supposed to read documentation, know your mentor(s) and discuss the project ideas, needs, requirements, difficulties, etc. but as many other GSoCers I couldn’t resist to code something. My goal for the last week was to write a very simple Qt application showing the power of Grantlee. The idea was to simulate that I am reading a message in Kmail and I want to change the theme again and again. You can take a look at the code in the soc-pim branch or: svn co svn://anonsvn.kde.org/home/kde/branches/work/soc-pim/kdepim/examples/mail_grantl...05.03.2008 Mike Arthur (mikearthur): Where is the love? I realise I’m probably going to get lynched for this but I think it needs to be said. If you, as a KDE developer, get annoyed with a KDE feature you didn’t write and feel like blogging about your bad interaction with a part of KDE or a spat with another KDE developer then please don’t. You have every right to do so but it isn’t good for you, it isn’t good for the other developer and it is really bad for KDE. The problem with a community like KDE doing the majority of their work online is that sometimes we forget basic social rules of interaction. If your blog is o...
