Time::TAI::Simple

Posted 07-30-2014 at 11:09 PM by ttk (Unpopular Positions: One Geek's Take)

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:
  • The number it returns

Datashack Stirrings

Posted 07-20-2014 at 09:54 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...

Geekbench

Posted 02-05-2014 at 05:04 PM by ttk (Unpopular Positions: One Geek's Take)

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...

Some Observations Regarding NSA Surveillance

Posted 10-26-2013 at 02:43 PM by ttk (Unpopular Positions: One Geek's Take)
Updated 10-26-2013 at 02:44 PM by ttk (Adding categories)

Some things to keep in mind regarding the mass hoovering of data communications a la Room 641A:

Communication lines transport packets of data, each of which contains metadata (including identifiers for the origin of the packet and its destination) and data (voice, video, internet traffic, etc). Collection software would inspect each packet and append entries to its own data store, including at least the source, destination, and time the packet was inspected (and possibly additional...

ZACL Changes Afoot

Posted 07-17-2013 at 08:52 PM by ttk (Unpopular Positions: One Geek's Take)

Lately, when working on Zacl (Zacl's A Concurrency Language), I've been trying to implement a parser for the language with Lemon.

I've despised lex and yacc (and their successors, flex and bison) since 1988, and most of the other compiler-compilers out there looked to me like remakes of lex and yacc, using different implementation languages and different syntactic sugar. But not Lemon -- Lemon is different. It inverts the relationship between the lexer and the parser, and uses nice-looking...
