Displaying formulas using HTML (via: More TVM–calculating the IRR : Algorithms for the masses – julian m bucknall)

Posted by jpluimers on 2012/10/04

I saw julian Bucknall post some beautiful formatted functions in a few of his Algorithms for the masses blog and wondered how he did it.

[a = P . r^N . \frac { (1 – r) } { (1 – r^N) }]

Why is his formula code looking so simple, and why doesn’t it display on my blog?

So I asked him (:

Hi response was “use MathJax“:

I’m loading the MathJax JavaScript library in my pages:
http://www.mathjax.org/

Here’s the post where I talk about it and how I tweak the expressions:
http://blog.boyet.com/blog/blog/tightening-the-feedback-loop-when-writing-latex-expressions-for-mathjax/

If you want to experiment writing such expressions, I have the page I’m describing in the above post online:
http://blog.boyet.com/blog/files/uploads/MathJaxFeedback.html

There are various ways to include the MathJax JavaScript, and if you do, you can use both LaTeX and MathML style formulas. Read all about it on the MathJax Getting Started page.

http Fiddler has joined the Telerik family (and Eric joined Telerik too)

Posted by jpluimers on 2012/10/03

Earlie last month, I missed this: Fiddler has joined the Telerik family (and Eric joined Telerik too)

So I missed the announcements here:

Fiddler Web Debugger – Letter from Eric to the Fiddler community.

and here:

Christopher Eyhorn’s blog > Here we grow again. Telerik acquires Fiddler. What’s next?.

Cool news (:

Jim Tierney published some great Delphi XE3 LiveBinding posts

Posted by jpluimers on 2012/10/03

Jim Tierney isn’t on DelphiFeeds yet, so below are a few links to his great Delphi XE3 LiveBindings posts.

Jim is one of the people that developed LiveBindings. In addition to that, he explains things very well.

He did some great posts on LiveBindings after Delphi XE2 got launched (he also did two great presentations on Delphi Live 2011 and CodeRage 6 – they got repeated on the last 24 hours of Delphi).

Now he is publishing a series of posts on LiveBindings in Delphi XE3.

These posts are recommended reading, more are probably on their way:

asp.net – Should the WebInfo file be excluded from SVN – Stack Overflow

Posted by jpluimers on 2012/10/03

When moving a truckload of stuff from Visual Source Crash, I came a long many .webinfo files.

I wasn’t sure they should be in TFS, and indeed they should not:

.webinfo should be excluded. (Some info about webinfo: How to copy and configure ASP.NET projects between different local computers)

Portable Library Tools extension: hopefully a Visual Studio 11 studio comes soon

Posted by jpluimers on 2012/10/02

Portable Library Tools extension is a great tool for creating assemblies that run on a variety of .NET platforms without recompilation.

I hope a Visual Studio 11 version of it comes soon.

While I wasn’t watching, Icecast released quite a bit of new stuff: libShout 2.3.1, Icecast 2.3.3 / 2.4-beta and Ices 2.0.2.

Posted by jpluimers on 2012/10/01

Because of a very busy project, I hadn’t watch the Icecast.org homepage for a while.

Well, this year they in fact did release some new versions that you’d think are purely maintenance releases but do have new stuff:

libShout 2.3.0 added WebM support, which is great, because it is a license free video format formerly known as VP-8 by On2/Google.

libShout 2.3.1 added Opus support, which is cool, because last month, IETF published it as a standard for use on the internet: RFC 6716 – Definition of the Opus Audio Codec.

Icecast 2.3.3 fixed quite a bit of security fixes, had some general bugfixes, allows for sources to be authenticated via URL (just like listeners can), and added support for VLCT playlists (that have much more meta information than M3U or PLS playlists).

(Hopefully Windows binaries get added soon).

Icecast 2.4 beta adds WebM and Opus support and a few bugfixes. Needs thorough testing though.

Ices 2.0.2 streams audio to Icecast, now supports RoarAudio and fixes a few bugs.

ESX/ESXi/vSphere BIOS Release Date to version mapping (via: the birdhouse in my soul: Which ESX version am I running on ?)

Posted by jpluimers on 2012/10/01

It is possible from inside a guest VM to determine the kind of VMware host it runs on by looking at the BIOS information and for instance map the version of VMware Tools to install.

Still need to find out about the 04/15/11 BIOS Release Date, but this should give me a start (vSphere matches ESX/ESXi):

VMware version BIOS Release Date Address (hex) (bytes)
ESX 2.5 04/21/2004 0xE8480 97152
ESX 3.0 04/17/2006 0xE7C70 99216
ESX 3.5 01/30/2008 0xE7910 100080
ESX 4 08/15/2008 0xEA6C0 88384
ESX 4U1 09/22/2009 0xEA550 88752
ESX 4.1 10/13/2009 0xEA2E0 89376
ESX 5 01/07/2011 0xE72C0 101696
ESX 5.1 22/06/2012 0xEA0C0 89920
