chanandler_bong | 1 year ago | on: The semiotics of barbed wire fence

I read an article a long time ago that drew a direct correlation between the need to contain/separate livestock in the American West and the battlefields of World War I.

Basically, as settlers moved westward, they needed to contain their livestock as well as separate sheep and cows. Sheep apparently eat grass down to the ground whereas cows don't, thus sheep would deprive cows of food.

So, barbed wire was developed for this purpose and the military saw the utility of it as well. Fast-forward to WWI and the vast battlefields there and needing an inexpensive way to slow enemy advances on foot. This led to the development of tanks to overcome the barbed wire obstacles. Machine guns also became more useful as a way to spray large areas when attacking troops were held up by the obstacles.

chanandler_bong | 2 years ago | on: For a moment there, Lotus Notes appeared to do everything a company needed

Back in the mid 90s, I spent a full year migrating my company and ~800 users across six sites from Exchange to Notes. I had no experience with Notes, and absolutely hated it when I started the project.

After a year of hacking, learning from mistakes, and countless hours of RTFM, we got it done. Email, calendar, file shares all migrated, cross-site replication, and some really great new features added in with workflows. I was really proud of it.

As soon as the last migration wave was complete, I called my manager to let him know that the long-awaited day had arrived. Exchange was dead, long live Lotus Notes! Literally, during that phone call he said "Ummm. Yeah. We are going to migrate back to Exchange because of some M&A coming up."

I was not pleased.

chanandler_bong | 2 years ago | on: Borgbase backups have been unavailable for 3 days

Pretty simple, really.

Pick a couple random files that should be in the repo, restore them from a random archive, check the md5sums against the source. If the md5sums don't match (or the file can't be found), something is wrong. I am mainly backing up RAW image files, so they should never change.

Basically...

$TEST_FILE=$(ls -p /source_dir | grep -v / | shuf -n1)

$TEST_ARCHIVE=$(borgmatic -c config.file list | shuf -n1)

borgmatic extract yada yada yada

md5sum $TEST_FILE restored_file

chanandler_bong | 2 years ago | on: Borgbase backups have been unavailable for 3 days

The fact that as a customer that is impacted by this, I only found out about it when my backups and automated test restore failed is worrying.

I get that things happen, but not realising that this was going to be a service impacting event does not inspire continued confidence. Sure, this situation probably won't happen again, but what else don't they understand about their infrastructure?

chanandler_bong | 3 years ago | on: The Black Ships Shock: A Historic Encounter That Changed Japan

Their biggest miss was not hitting the fuel dumps and repair facilities. Taking out a few ships, even carriers, would be easy to replace. Wiping out the logistics support capability would mean that ships would have to return to the US west coast to refuel/repair.

That would have been a major disaster. Pearl Harbor was just an irritant and catalyst.
