Gartners Hype Cycle

Gartner analyses the maturity of more than 1,800 technologies trends. Based on the maturity of a technology or trend a decision can be made to adopt or ignore, postpone or adopt the innovation.

In 2010 Gartner published the ‘2010 Special Report’ and consisted of 75 individual Hype Cycle reports, each of which gives a snapshot perspective of a key area of IT or business.

The IT industry acts on trending topics by creating products or solutions and convincing customer to adopt a certain trend or technology. Current trending topics are ‘Bring Your Own’, ‘Consumerization of IT’, ‘Cloud Computing’ and ‘Hosted Virtual Desktop’.

A trending topic (for many years) in The Netherlands is ‘Het nieuwe werken’ (The new working). A trend where flexibility, working from any location and using social media is accepted

WinPE: Restarting DHCP client service

Written by Ingmar Verheij on July 7th, 2011. Posted in Deployment

A bare-metal deployment is build using Altiris Deployment Solutions (HP Rapid Deployment Pack, to be precise). When a client boots Windows PE 2.1 to execute a job (installation of operating system) it doesn’t seem to get an IP address from the DHCP server (Restarting DHCP client service: retry x).

This is strange since the WinPE 2.1 image is downloaded via a PXE boot which acquired a IP address from the DHCP server without problems, the DHCP mechanism is working.

This caused me some serious headache a few months ago (at another customer). I investigated the problem and found the cause of the problem.

Remove all tables from database

During the setup of a LoadTest with the DeNamiK LoadGen I created loads of tables in a SQL database. The content of the tables was irrelevant, pure for testing purposes, and needed to be cleaned.

Deleting them all by hand, one by one, would be tremendous job. As an IT guy I dislike repeating jobs, so I searched for an automated solution.

Since I have limited permissions I don’t want to delete the database and recreate it. This would require more permissions than available, requires me to reconfigure the permissions (etc) and would raise questions by the DBA’s.

There is an undocumented stored procedure called ‘sp_MSforeachtable’. This stored procedure executes a command for each table in the database, for instance ‘DROP TABLE’.

The following command will delete all tables in the active database (use with caution!)

EXEC sp_MSforeachtable @command1 = "DROP TABLE ?"

My speedometer is lying!

Speedometer (100 KM/h)When driving in my car I regularly look at my speedometer, just to make sure I’m not driving too fast. But how usefull is this if the speed I’m reading on the speedometer is wrong. I knew there was an offset, but I never checked how much the offset was.

After “extensive” research my conclusion is: My speedometer is lying!

Recently a law has changed in The Netherlands, due to this new law the maximum speed is increased from 120 KM/h to 130 KM/h. This raised some questions to a lot of drivers, usually about speeding tickets. Since the police is using a correction of 3% this means you can drive 133,9 KM/h without getting a speed ticket, right?

Well, it depends on where you’re looking for the speed you driving. My speedometer has an offset of roughly 10%, which is a lot IMO.

Why is my iPhone battery draining?

Written by Ingmar Verheij on May 20th, 2011. Posted in iPhone

Last weekend I was at PubForum (now E2E Virtualization Conference) in Dublin Ireland. During the sessions I used my iPhone once in a while to check twitter, nothing more then usual.

My battery however, was draining really fast. I had to charge my iPhone three times a day and still found myself with an empty battery in an Irish pub.

 EmptyBattery

Battery life of an iPhone is short, especially when you use 3G, WiFi, GPS, Bluetooth etc. In Ireland I had most disabled, WiFi was sometimes connected. Even closing all apps and rebooting the operating system did not solve the problem.
