Enable Internet Calendar Publishing for Exchange 2013

If you want to share your Exchange 2013 calendar, or export your calendar to an iCal ICS file, read on. This is what I did on my calendaring server named Verdandi.

In 2011, I wrote in the article “Calendaring: Exchange can publish to ICS, defaults to insecure” on this website:

ICS (iCal) is a file format for calendars. Most calendaring software uses it. For example, you can import / export it to Google Calendar. If you have a Google Calendar, you can “publish” your calendar to an ICS file, so you can use it with other software like Mozilla Calendar or web services. Read the rest of this entry »

F.lux or no F.lux and Linux!

I’ve been using a program called F.lux or Flux for over a year now.

The program is based on the research that blue light keeps you awake and alert. Not something that you’d want at night. So this program adapts the display to show warmer colors at night. You can read more about the program on it’s website. Normally flux adapts the colors as the day progresses and night starts but I preferred to keep the colors warm (yellow-ish) all day long. It’s really easy on eyes even for those long hours spent staring at computer screen.

However Flux for linux lacks the features that it’s Windows version offers. Most particularly the options of controlling the color phase during the day time. Also getting it to work on a dual monitor setup was more effort than I intended to spend. So I decided to fore go the program altogether in favor of changing the color profile of the monitor itself.

Most monitors have the color settings that allow you to pick the RGB (Red Green Blue) levels in your monitor. I fiddled around with mine and set the levels of R-100, G-100, B-0. Hence getting the blue component out of the display and achieving the same effect as flux.

Try it out yourself and see if you can adjust to it. I’d suggest using the default settings of flux till you stop noticing the yellow color of the monitor and then moving to yellow color altogether. I’d recommend giving it two weeks of usage before making a decision on if you want to stop using it or not since it feels odd initially and it takes a bit to get used to.

Let us know if it worked out for you!


Edit – Alisa @ NestMaven has a nice writeup about circadian rhythm. Blue light impacts your sleep cycle. You could read more about it here.

How to add a custom filetype to Linux


In this example, we will add support for MHTML / MHT files.

Note that the MIME type for MHTML is not well agreed upon. Used MIME types include:

  • multipart/related
  • application/x-mimearchive
  • message/rfc822

According to a StackOverflow question, message/rfc822 should be used. A recent discussion on FreeDesktop, however, recommends application/x-mimearchive as a subtype of multipart/related. I will use message/rfc822 in the examples below and have added this unclarity to the Wikipedia article. Read the rest of this entry »

Get SQL Agent service starting

Today I was struggling with Microsoft’s SQL Server. I could not get the SQL Agent service starting. Maybe my experiences can help you.


Sometimes the SQL Agent service will not start, and it is quite hard to get the cause of this when the Error log doesn’t show much. The hints below were gathered from various websites and online forums, and some of them were tested with a Microsoft SQL Server 2008 R2 stand-alone instance running on Windows 7.

General testing

To get some idea of what is wrong, do this in a command shell: Read the rest of this entry »

Installing Haiku directly to a disk partition


Haiku is something like Windows or Linux: an Operating System (OS). Some geeks like to play with alternative operating systems; it you are one of such geeks, you might want to give Haiku a try. Haiku is very fast and easy to use, but currently there are not many applications you can use with Haiku.

Haiku is a new open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

In this post, I will describe how to install Haiku on a spare harddisk partition directly without using a CD-ROM or USB memory key. I furthermore assume that you already installed Linux on another partition. Read the rest of this entry »

10 Must Have Apps for the new Apple iPhone 5

The all new iPhone 5 was launched on September 12, 2012 (watch the keynote here). With a better processor and a bigger screen, iPhone 5 offers few more opportunities to app developers to harness the new hardware features. Although the iPhone 5 (which comes with the new iOS6) has a native integration with Facebook and Twitter, there are a host of other apps (free + paid) that are definitely a must have for the iPhone 5. This article lists out ten must have apps for the iPhone 5. Although the article is particularly directed towards the new iPhone, all of these apps are also compatible with iPhone 3GS, 4, and 4S.

Photography now at 1,000,000,000,000 frames per second!


Move over high speed camera here comes fem-to camera. Imagine being able to capture frames so fast that you can see light moving a millimeter of a distance and no this is not fantasy but something that actually has been done. Now think about the various scientific capabilities of such a technological wonder; from studying light waves as move and interact with various objects and mediums to seeing around the corner, checking if a fruit is ripe by shining light on it and possibly many more.

The paper on how they use this technology to see around the corners can be found on
