What a week. Not only did I start on one of the first cloud engagements in EMEA but also one of the largest clouds was implemented in Iceland and because of this (ash) cloud I got stuck in the UK. I wanted to get the weekly top 5 done in the morning but ended up spending my morning on something else and the afternoon walking around in London. I did manage to squeeze in a couple of minutes this morning to get this article out though, and just before you start reading don't forget the vExpert "awards" for 2010!
Richard Garsthagen - unofficial SDK for VMware View Welcome to this first part of the ‘unofficial SDK for VMware View”. You might wonder, why “unofficial”? Well, simple, VMware View is one of the few products from VMware that does not have an SDK So if you want to script/program/automate anything against VMware View, you are out of luck. That is, officially you can not. VMware View uses Microsoft ADAM (Active Directory Application Mode) to store its data. After a day of googling and puzzling, I was finally able to figure out how to do some of these ADAM calls myself using visual basic and powershell. In this part 1, I want to share 2 beginning powershell scripts with you.
Scott Drummonds - Windows Guest Defragmentation, Take Two Before I describe the test and its results, I want to share an important point on guest defragmentation. Most of the computer literate are aware that file fragmentation–the separation of logically contiguous pieces of a file–can hurt storage performance. But many may not realize that free space fragmentation is as big of an issue. When free space is fragmented, writes take longer and files are re-fragmented rapidly. PerfectDisk defragments files and free space and the results below benefit from both of these improvements.
Stuart Radnidge - Be Agile Agility is another buzzword that goes hand in hand with Cloud, but what I’m referring to here is more aligned with Agile as a philosophy or methodology rather than the conventional interpretation (although of the course the 2 are closely linked). Agile is most often used for software projects, so you may initially think it’s a bit strange to use for something that is as much infrastructure as it is software but trust me, it works exceptionally well.
Eric Sloof - What’s faster E1000 or VMXNET3 – let’s see what PassMark’s PerformanceTest says When both virtual machines are hosted on the same ESX server and only using the “left side” of the distributed virtual switch the network performance is 300% faster. I know these network graphs show details of the TCP/IP network transfer speed (in kilobits / sec) over short period of time and are not really representative, the average network speed may be limited by the LAN card, the CPU or network infrastructure such as firewalls and switches. But I’ve learned two lessons, the VMXNET3 is faster and local ESX traffic outperforms external traffic by 300%.
Gabrie van Zanten - [Gestalt] vBlock, great product, just not for you What I don’t understand though is where the bottleneck is in a Vblock type 1 to use only 48GB? When starting with 2 chassis there is plenty of memory that could be added before adding a 3rd chassis. CPU shouldn’t be the problem, since the Vblock type 2 blades are the same B-200 blades, all running 96GB RAM and are able to host more VMs per blade than the Vblock type 1. Would storage be the bottleneck? Actually, I doubt that, since adding a 3rd or 4th chassis would put more VMs on the storage and ask more IOPS from the storage, which the Vblock can deliver according to the specs. Then why would the balance be gone when adding more memory? I have no answer on that, I can only say that where 4 chassis with each 6x 48GB + 2x 96GB blades will give me 1920GB RAM, a non-supported config with 3 chassis of 8x 96GB blades would give me 2304GB RAM and thus save me buying that 4rd chassis.
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...
