Fping Video

I was checking some backlinks yesterday when I discovered that Amit Vartak made a complete video tutorial of Fping on SecurityTube. It describes every option of Fping version 2.17 . I've added a lot of cool stuff afterwards but it's still great to see that people like the software enough to create video tutorials. So thanks for creating these, I really appreciate it. There are 4 videos and I've embedded them all here.

Fping 2.21

I took some time of other projects to update my Fping application. I've corrected several faults that have been in there since the first release but always went unnoticed. One of the things we corrected was the amount of data sent. We used the first 4 databytes to store timing information. These 4 bytes became obsolete when I introduced a new timing system. Unfortunately I forgot to remove those 4 bytes of data. These 4 bytes are now replaced with regular ping data.

I also adjusted the Windows timer resolution. Seems this was causing problems on certain systems and users where unable to ping fast enough. Now pinging should be lightning fast on all systems.

More information on Fping can be found here.

Watchdog - O - Matic 5.02 released

I'm glad to announce the latest Watchdog - O - Matic release. I've been very busy the last few months just to get this right. You might have noticed this by the number of blog post.

The biggest new feature of this version is flap detection. This allows Watchdog - O - Matic to block programs that keep on crashing instead of trying to restart it over and over again ad infinitum.

You can find more information here.

HP 48G RAM upgrade

One of the things on my desk that I use all the time is my old faithful HP 48G calculator. I originally bought it some 15 years ago when I was a student. The HP uses Reverse Polish Notation which works great. I'm so used to working in RPN that I simply hate using regular calculators. That's one of the biggest reasons I still use it today cause, let's face it, I don't do Fourier or Laplace transforms these days.

The only problem I had with the machine was that I purchased the "budget" version ($200 on a student budget 15 years ago wasn't exactly cheap) which had 32K RAM. This means it can hold only 1 program most of the time. Some programs don't even fit at all. But then I stumbled on this page which explains the process of upgrading the HP 48G to 256K RAM. I loved the idea, but I'm not the most skilled person when it comes to soldering SMD chips or any other delicate operation for that matter. So I was a little hesitant to do this cause there was a possibility of ruining my beloved calculator. But I figured I'd try anyway.

I stopped after soldering the 128K RAM chip cause that was difficult enough for me and they warn people that soldering another 128K chip on top was very hard. The result: a HP 48G with 128KB RAM and a very ugly front. I don't mind the front at all cause when people ask me what I did to my calculator, I have a very nerdy story to tell.

Weather Station Crash

I was checking the backlinks to my website when I noticed this link.

I ran the software successfully for a month but within days of going on holiday the weather station software would inexplicably randomly crash every couple of hours but the next day it seemed to sort itself. This was short lived as within 12 hours of leaving to start my holiday it crashed and remained so until I returned. On my return I tried a number of things to improve the reliability including daily re-boots of the computer but it did not stop the intermittent crashes. I searched the internet and found a program called Watchdog - O - Matic from Kwakkelflap. This program monitors running programs looking for problems. I tried the trial version and found it successfully restarted the program after a crash. I purchased the full version and have been very pleased [with] it. I could now run my weather station reliably 24 hours a day.


I think it's a great example of someone using Watchdog - O - Matic.

Service - O - Matic 3.00 released

I'm happy to announce that Service - O - Matic 3.00 has been released. It took a while to get to this version, but I wanted to get it perfect. I corrected some user rights problems and included some new features like Flap detection among other things.

With this release all conversions to 64bit are finished. I also tested everything on Windows 2008 Server so I'm confidant that our applications are ready for the future.

It doesn't end here of course. I'm still working on the next Watchdog - O - Matic version that has some great new improvements.

Code signing, part two

I just received word from Comodo. Seems I can't use their certificate in Vista making it useless for me. You'd think companies would adapt to a new OS after a year. Too bad they didn't tell me about this a week ago. Better yet: warn me when ordering the certificate that it can't be used on Vista. I received a refund the minute I asked about it, so no complaints there.

I'll be checking other certificates, but I don't think I'll postpone the Service - O - Matic release.
