Reading other files from the past…

System & Utilities

While being stuck in text layouting problems during my work on writing an import filter for CDRv4 files for Calligra, I discovered that the import filter for the xfig format is currently disabled from built and needed some porting.

So for some change and a break and the old files I have around in the xfig format I gave it a try, should be just a few hours… Well, of course that became a few days, but now the import filter works at least somehow comparable good as it might have done before.

E.g. this old file

is now imported as

You see that text and arrows still need some work, and so do pattern fills, but otherwise it looks good. Except for:

??? How to translate x-splines to quadratic/cubic Bézier curves ???
XFig was used to be the reference implementation for that special type of splines. But so far I have not seen an explanation how to translate those to the kind of curves which are supported in ODG/SVG. Any help welcome! Currently those curves are imported as simple polylines.

If you want to give the filter a look, it currently lives only in an own branch in the Calligra repo, named filters-karbon-xfig-recreate2012.

08.03.2010 Top 5 Planet V12n blog posts week 09
Top 5 Planet V12n blog posts week 09 A lot of you have been very busy this week, patching ESX hosts(That would be you Jason ;-)) and hopefully reading all the excellent articles being aggregated on Planet V12n... Duncan Epping - CPU/MEM Reservation BehaviorThe above paragraph is a bit misleading , as it seems to imply that a VM has to access its full reservation. What it should really say is “Memory which is protected by a reservation will not be reclaimed by ballooning or Host-level swapping even if it becomes idle,” and “Physical machine memory will not be allocated to the VM until...

19.04.2010 Top 5 Planet V12n blog posts week 15
Top 5 Planet V12n blog posts week 15 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!

07.12.2010 Performance and Use Cases of VMware DirectPath I/O for Networking
Performance and Use Cases of VMware DirectPath I/O for Networking Summary VMware DirectPath I/O is a technology, available from vSphere 4.0 and higher that leverages hardware support (Intel VT-d and AMD-Vi) to allow guests to directly access hardware devices. In the case of networking, a VM with DirectPath I/O can directly access the physical NIC instead of using an emulated (vlance, e1000) or a para-virtualized (vmxnet, vmxnet3) device. While both para-virtualized devices and DirectPath I/O can sustain high throughput (beyond 10Gbps), DirectPath I/O can additionally save CPU cycles in ...

Guest Post: How to write a book or blog (Part 1) Have you ever read through various books or viewed different blogs thinking to yourself, heck, I could do that or perhaps even better? Ok, what is preventing you from writing a book or blog? If you have started and have not yet published your blog or book, what is the hold up?  Why do you want to write a book or blog? Over the years, I have written three formally published books (i.e. via a traditional publisher with and ISBN and a Library of Congress registration), and collaborated on several book projects with others. Additionally, I ...

Top 5 Planet V12n blog posts week 16 Week 16, no small talks just the facts: Eric Sloof - Online Training – Automating vSphere with the VIX APIThe API 1.10 Beta was released last February; this is the preliminary standalone VIX release that runs with VMware vSphere 4.x. This release also bundles earlier VIX libraries, including the libraries delivered for Workstation and VMware Server. I’ve created a new tool called the vmFilemanager; this tool is completely built on the VIX API 1.10 Beta. It’s not available for download yet, but I’ve recorded a demo which show how to copy files into a vi...
