Ninth Runniversary
Yesterday was my ninth runniversary. Like my first day running, I ran on the treadmill while listening to Broken. Unlike the first time, I only listened to it once, and covered 4.48 miles during the duration of the EP, thanking God every step of the way.

I'm confident in knowing that the bone in my ankle has healed completely now; however, I'm still rebuilding the muscle in that ankle and the rest of that leg. There was significant atrophy during the early phases of recovery. Slowly as it may be, I am making progress, and I am thankful for that.

Tenth Runniversary
Today is my tenth runniversary. It's been a decade since I first stepped on that treadmill. Like my first day running, I ran on the treadmill while listening to br\oken. I've had some set backs in my recovery. Not properly rehabilitating the atrophy in the left leg has caused some problems with the muscles around my hip. Listening to my trainer only made it worse. But now I'm taking care of it properly. Like that first day ten years ago, I have a goal I am working toward. This time it is the Dublin Marathon in October. This will be marathon number 13. I don't expect to PR. I think 10 minute miles are a much more reasonable goal at this point, but frankly I'll be happy just to cross that finish line. It's been a long, hard road out of Hell, but God has been by my side and put some amazing people in my life to help me along the way. I have to thank the Giraffes for today. I have to thank the Giraffes for much of my life this last decade. I was heading for an early grave, and they changed that. Giraffes, I thank you from the bottom of my heart and I look forward to running the LTC and many other races with you in the next decade.

Take back your privacy
Recent surveys have found that 76% of [the most visited] websites in the world cotain trackers from google and 24% contain trackers from facebook. This has been reported by CNBC, PC World, The Verge, Fortune, and Breitbart.

Almost anywhere you go on the internet, they are following you, building a profile on you, and selling that information, your information, to the highest bidder. Even if you don't have a user account for google or facebook "services," they've built a profile of you using this surreptitiously collected data.

It turns out there are some steps one can take to prevent these companies from following you wherever you go. It's not perfect, but it helps a lot. First, don't use Chrome. Second, install ad-blocker plugins for your browser. Third, use your firewall.

It turns out Google and Facebook are large enough that they have their own Autonomous Systems (AS) composed of numerous subnets. Google owns AS 15169, while Facebook owns AS 32934. Using a little bit of shell, it's relatively easy to look up all the subnets owned by these companies.

whois -h whois.radb.net -- '-i origin AS32934' | grep "^route:" | awk '{print $2;}'
whois -h whois.radb.net -- '-i origin AS15169' | grep "^route:" | awk '{print $2;}'

That's a lot of subnets. Because I have different operating systems on different computers and still want to block traffic to and from all those IP addresses, I've written some simple scripts to add rules to various firewalls. I have scripts for IPFW on FreeBSD, IPTables on Linux, and the Windows Firewall that should work from XP SP3 through Windows 10. I've only tested it on Windows 7 and Windows 10, and it worked in those.

All of these scripts can be found in this directory. The IPFW and IPTables scripts are self-contained. For the Windows command shell batch files, the *ips.txt files are also needed.

I have to say, the internet looks very different with these firewall rules in place. There are noticeably fewer advertisements and pages load faster. Embedded YouTube videos and Instagram photos don't appear. Sometimes the frame disappears, sometimes you get a "failed to connect" page appearing in a frame in the middle of a page. (Yes, these rules block YouTube and Instagram; they are owned by google and facebook and reside in the subnets owned by those companies.) On a relatively rare occasion, I come across a site using some sort of javascript or css or something hosted by a machine in one of those ASs and that will be blocked. Sometimes the site handles that gracefully, sometimes it stops being functional. A small price to take back your life.

Update: Twitter has trackers on a decent amount of sites out there too, so I've added scripts to block Twitter's AS 13414 as well. Those scripts are in the same directories as the others.

New PGP Key!
So apparently Evil32 happened. Approximately 24,000 PGP keys were generated that had collisions with the 32-bit short IDs of existing keys. Then someone decided to use those conflicting keys to generate revocation certificates and upload them to the keyservers. Joy.

Though my old keys still work, they were affected by this mass revocation of collsions. I have created a new key which can be found at http://skinnymf.com/~mforde/mforde.asc.

On a related note, if anyone is interested in Key Signing Party, shoot me an email. I haven't been to one of those since college.

WTF?
I'm used to guitarists mocking the bass and bassists. It doesn't bother me too much. But this... This irritated me. A lot.
Today at work there was a group of people talking about Rock Band and Guitar Hero 3. None of them actually know how to play intstruments but they claim to be great at these games. They seem to believe this entitles them mock bassists.

• "Oh man, bass is so easy. It's the guitar that's the hard part. Yeah, I'm on expert on the guitar."
• "Yeah, bass is so stupid."
• "So It's me, my brother, and my sister. I play guitar, he's on drums, and my sister sings."
  "what about bass?"
  "My friend just got Guitar Hero 3. I'll make him play bass."
  [Both laugh]
• After making statements indicating this person believes he actually is better than Tom Morello, "After you make Tom Morello or Slash your bitch, they play bass for you."

chdir(2)
So today at work another developer many years my senior, with many more years experience than I, came to me with a Unixy problem.
"When I have a program, how can I have it so the current working directory for all processes it starts isn't the one that it started in?"
"chdir."
"No, I want so that if this process starts something like ls, when ls stats 'dot' I want 'dot' to be the directory that process wants it to be, not the directory that process was started from."
After about 15 minutes of me suggesting chdir while he said that's not what he wanted but then describing chdir, I finally wrote something along the lines of the following

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

int
main (int argc, char *argv[])
{
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/tmp");
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/etc");
  system("/bin/pwd");
  system("/bin/ls");
  chdir("/");
  system("/bin/pwd");
  system("/bin/ls");
  return 0;
}

I compiled that, ran it, showed him the output. He said, "Yeah, that's what I want to do."
I showed him the code.
"chdir does that?"

Alpha
Due to the power failure, there was the loss of several hours of work. Last night I installed FreeBSD 6.2-RELEASE on an old DEC AlphaStation 200 I have. I had started building a new, smaller kernel for it around 23:30 last night. It had not completed by the time of the power outage. I have restarted that build.
Any one reading this would reasonably ask, "Why are you not as confused/angry/annoyed with a compile that was not finished in 7 hours as you were about one that took 3 hours?"
The answer is simple. This AlphaStation is powered by a 100MHz DEC Alpha EV4 CPU and has 64MB of RAM. To the best of my knowledge, DEC made this machine around 1994 or 1995. I expected the build to take a long time; the machine is around a dozen years old.

How long does it take to build a linux kernel?
It has been a number of years since I built a linux kernel. Slackware 9.1 was the last GNU/Linux distro I used before switching back to BSD. Tonight I put together a machine from some old parts (1.2GHz celeron with 256KB cache, 256MB RAM, 20GB hard drive) and installed Slackware 12. I customized a kernel configuration and attempted to build it. I don't remember the 2.4 kernel taking as long to build as this 2.6 kernel. It took nearly two hours. Granted, this machine is fairly old, but 2 hours? After I complete the tasks for which I needed this setup, I'm going to install an older Slackware with the 2.4 kernel and build that. I may also install FreeBSD and NetBSD and build their kernels. I'd like to get an idea how long it takes to compile other kernels on this rig.

Removing Windows 7 Boot Loader
Removing the Windows7 boot loader is just like removing the Vista boot loader. The key being running the command

\boot\bootsect.exe /nt52 ALL /force

from the Win7 install DVD. More info at this site.

Fireside Chat


Tonight I signed up for the Fireside beta. They asked for all my social media accounts to prove I'm a human. The problem is, I don't have a twitter account, a facebook account, instagram, etc. Years ago I took the advice of numerous psychology studies and my own therapist's advice and got off the social media platforms. It was one of the best things I've ever done for my mental health.

So hopefully this blog, though infrequently updated (and slightly broken since the last major perl update), will serve as proof to the people at Fireside that I am human and not a bot.

It was the Astonishing Legends Podcast that led me to Fireside. It would be nice to use it for one of their interactive live chats sometime.
