RIPE Atlas – Total Availability : 100.00%

Yes, this is blatant bragging. But realistically, this is more a function of my ISP (Verizon FiOS) and my electricity supplier (PECO) than my abilities. To be fair, it is more contingent upon no power failures than anything else. I do have a UPS, but that’s only good for about 10-20 minutes. For August 2021, my home network had 100% uptime, according to RIPE. I’ve been hosting this device since 2013-05-29 (just over

It’s always done well by me. This what the cable tester looks like from the outside.

link request spammers – sometimes they help

If you have a blog, or anything online, I’m sure you have received an email saying: Hey, great article, would you mind linking to my website please? A few days later: hey! did you get my email? Then later still: I know you’re busy…. The one I received today was at first annoying but then turned out helpful. I went to that blog post but I couldn’t find a link to Wikipedia anywhere.

Right up until you need it, resilience looks like waste

This sounds slightly political, and it is. Intentionally so. 1. the capacity to recover quickly from difficulties; toughness. “the often remarkable resilience of so many British institutions” 2. the ability of a substance or object to spring back into shape; elasticity. “nylon is excellent in wearability and resilience” Christophe Pettus recently said: Right up until you need it, resilience looks like waste If you use ZFS, you should know about this issue. For

Archives are important to retain and pass on knowledge

Archives are important. When they are public and available for searching, it retains and passes on knowledge. It saves vast amounts of time. Case in point I started the copy-backups-to-tape process today. This appeared on the tape server: Jan 7 19:12:08 r720-01 kernel: (sa0:mps0:0:5:0): 64512-byte tape record bigger than supplied buffer Damn. Do I have a tape problem? Search results When searching for this, I found this FreeBSD Forums post from 2016 where

Registering FireTV – unable to receive verification code on phone

I was setting up my FireTV (seems to be a TV with built-in FireStick functions). I was stuck, waiting for a verification code which never arrived on my phone. I was expecting an incoming text. I was wrong to expect that. I had gotten to the stage of logging in with my Amazon credentials and was getting told (and I paraphrase here): Because of the way your account is set up, your login

Why is my network offline? An investigation

Happy New Year. This morning I received an email at 4:50 AM local time telling me that my camera system had been offline for 10 minutes. Based on that, I tried to access my internal monitoring system from outside. Nothing. Later emails indicated other external systems had issues connecting to the internal network. As I type this, I just arrived at home, I’m sitting on the couch and I’ve not touched the network

Where is your tech passion?

You like tech. You know you like it. Do you know what part of tech you are most passionate about? I credit a Google employee for the following idea. It was told to me while I was at the FreeBSD Foundation booth at GHC 2016. The following is a relatively cheap project you can do in your spare time, weekends, and evenings. For the following tasks, blog about each step, in sufficient detail

Greg Truskey, TruCo

I’m writing this to document the facts. I’ll leave adjectives and opinions to you. Greg Truskey, TruCo was hired to perform renovations which started in August 2015. The estimate was 11 weeks. He was on site from about 9am to 3:30pm. Arriving earlier or late was uncommon. On days he would not arrive, we would not be notified. It would be fine weather, and he would not be present. You will recall the
