My name is Yermo Lamers and this is my personal website. To get in touch with me, please use
the Contact Yermo page.
YML.COM is a place where a few friends of mine and I post and discuss things we're interested in which range from motorcycles and boats to technology, software, politics and the environment.
I wrote all the software that runs this site for my company
DTLink LLC, so if it doesn't work or errors out it's my fault.
The underlying framework, called
formVista, I open sourced some time ago. The rest, called
MOBIE, I am planning on open sourcing once I get some time.
Check out the blue navigation links on the left for links to the rest of the site.
The rest of this page is just a collection of articles I and the other members of YML.COM find interesting.

Looks like an old idea for fixing excess atmospheric CO2 levels is gaining new life, and may prove to be practical after all: seeding the oceans with treated limestone.
Supporters claim this approach would not only increase the ocean's ability to absorb CO2, but fix the PH problem (acidification) created by the increased disolved CO2 levels as well.
Proponents are further claiming that this could realistically drop atmospheric CO2 back to pre-industrial age levels(!). And on top of all that, the project's being run open source style.

Our network is now multi-homed running BGP across two T1's; one connected to Qwest and another connected to Verizon.
The Qwest guys absolutely rock. They have been above the call of duty helpful. Tweaking BGP to get it to work right can be an error prone process.

Nothing like a little very serious doom and gloom from slashdot:
"While we bemoan the current oil crisis, I ran across an editorial that led me to research a more immediate threat. Ramped-up production of flat-panel displays means the material to make them will be 'extinct'
by 2017. This goes for other electronics as well. Quoting: 'The element
gallium is in very short supply and the world may well run out of it in
just a few years. Indium is threatened too, says Armin Reller, a
materials chemist at Germany's University of Augsburg. He estimates
that our planet's stock of indium will last no more than another
decade. All the hafnium will be gone by 2017 also, and another twenty
years will see the extinction of zinc. Even copper is an endangered
item, since worldwide demand for it is likely to exceed available
supplies by the end of the present century.' More links at the journal entry."

An IEA study released on 1 July says world oil supplies will likely remain stretched with little excess capacity through 2013.
This does not bode well for consumer prices, as the cost of energy generally cascades into multiple sectors of the economy; The Wall Street Journal has the details here.

The IEA (the Paris based Independent Energy Agency) is in the middle of an across the board evaluation of the condition of the world's oil fields.
The study results won't be released until November, but already, industry insiders and analysts are suggesting that the results may describe a much tighter world oil supply than anyone with real credibility has previously suggested.
How this may affect world oil markets, economies, and consumers remains to be seen. But already, Goldman Sachs is calling for oil prices of $200 a barrel by next year--hold onto your hats.
Meanwhile, get the details here from the Wall Street Journal.

Many folks who are forced to multitask on an ongoing basis already understand that multiple demands on attention can slow you down and carry significant switching costs. An article over at the Atlantic looks at this in detail; you can read it here.

As reported on slashdot:
"The effects of mobile phone radiation on sleep were studied in Sweden in a laboratory experiment
where subjects were exposed either to 884 MHz GSM radiation or placebo.
The study finds that compared to placebo, in the radiation-exposed
subjects there was a prolonged latency to reach the first cycle of deep
sleep (stage 3). The amount of stage 4 sleep was also decreased.
Moreover, participants that otherwise have no self-reported symptoms
related to mobile phone use, appear to have more headaches during
actual radiofrequency exposure as compared to sham exposure."

This was a head scratcher.
I had the misfortune of working on a Solaris 10 server today that exhibited the most bizarre problem. Despite having Mysql 5.0.45 installed in /usr/local/mysql and explicitly setting --with-mysql=/usr/local/mysql PHP configure option, phpinfo() consistently reported that the Mysql Client API version was 4.0.24.
I couldn't for the life of me find any mention of libmysqlclient.so.12 on the machine. Because my access was restricted, I couldn't easily do a find / -name "libmysqlclient.so.12".
As unlikely as it sounds, the 4.0.24 Client API version was getting pulled in as a result of the --with-openssl PHP configure option. It worked as follows:
- In their infinite wisdom, Sun Microsystems decided to ship old versions of open source software and install them in a completely non standard location "/usr/sfw".
- The openssl libraries are installed in /usr/sfw along with Mysql 4.0.24.
- The PHP Configure script knows about the /usr/sfw directory on Solaris and will look for libraries there.
- Once Configure finds the openssl libraries in /usr/sfw it includes /usr/sfw/include and /usr/sfw/lib into the Makefile INCLUDE and LD search paths /BEFORE/ /usr/local/mysql/lib and /usr/local/mysql/include.
- As a result, during the make, the linker finds libmysqlclient.so.12 in /usr/sfw/lib instead of /usr/local/msyql/lib.
The solution is to either uninstall the Solaris 4 package or to upgrade it using instructions found here:
http://www.sun.com/bigadmin/features/articles/samp_setup.jsp
If you can't do either you hack the Makefile and edit the paths by hand.
Have I mentioned recently how much I hate Solaris? Actually I hate it more than I do Windows, and that's saying something.
