Two things: First, my wife tells me this blog's interface sucks, and she hates trying to read it. Apparently it's horrible for users who do not have an LQ account. I'm kicking the tires on some alternatives.

Second, I've uploaded Time::TAI::Simple to CPAN. It provides a high-resolution count of seconds elapsed since the beginning of the epoch, much like Time::HiRes, but un-"corrects" for the IETF's leapsecond adjustments.

This means:

Datashack Stirrings

Posted 07-20-2014 at 08:54 AM by ttk (Unpopular Positions: One Geek's Take)

One of my ongoing projects, for the purpose of facilitating other projects, is the conversion of our wellhouse to a "datashack" and light workshop. The goal is to run various computers in it without introducing undue noise or heat to the main house.

It's been a while in the coming, but it's coming. Yesterday marked two big steps: I moved my computer cabinet from the garage (where I basically never got to run the systems mounted in it) to the wellhouse, and I installed...

A completely uninteresting, self-centered whinefest

Posted 06-19-2014 at 01:37 AM by ttk (Unpopular Positions: One Geek's Take)

It seems fitting that my first new blog entry in months should be a means of procrastination. I have lofty goals for this space, but they are thus far mostly unfulfilled. This study in self-pity shouldn't be here, but I feel the need to write about it, and I can't think of another place to do so. Maybe I need a journal? Something where I can write the stuff that doesn't matter?

If you hadn't figured it out already, you can refrain from reading this post and your life will be no...

Memory overhead of Python and Perl associative arrays

Posted 05-06-2014 at 06:51 PM by ttk (Unpopular Positions: One Geek's Take)

I've been measuring the relative memory overhead of perl hashes and python dicts (essentially the same data type, both associative arrays).

These measures are necessarily approximate, since they resize differently as the tables fill, but the overhead comes to about 57 bytes plus 76 bytes per element for perl, and 264 bytes plus 123 bytes per element for python. Both of these are for numeric-to-numeric mappings.

About halfway through this exercise, it occurred to me...

Because none of us have infinite time and money to throw at our computer hardware, it's nice to be able to look at a benchmark and gauge whether it's worth it to spend a little extra cash at a more powerful CPU, or one with a different memory subsystem, or a solid state disk, etc.

For this, we have system benchmarks.

For a system benchmark to be useful to a person, it must measure the system's capability to perform the kinds of tasks that person needs their system to...
