Alternate Side of the Street Parking

I’ve gotten a number of tickets over the years because I misinterpreted the alternate side of the street parking signs on our street. Yes, I’m embarrassed that somebody whose livelihood depends on being able to interpret and write complex boolean expressions should have trouble with these signs, but there you have it. But I resolved to not get caught out again, so this is what I did:

  1. Installed IFTT on my phone
  2. Created two PNG files, one that says “North” and one that says “South”, and set up two lines in my crontab on my computer that copies the appropriate one to my public web server when the parking rules change over.
  3. Created an IFTT rule that when I get close to home it displays a “rich” notification including which ever image is on my web server
  4. Created two IFTT rules to send me a notification when the parking rules change over.
  5. Created a shortcut on my home screen on my phone so I can check the image on the web server if I miss the IFTT notification.

If I get another parking ticket, it won’t be because I didn’t try.

2018 Racing Calendar

I don’t think I did one of these last year. This year, because of the extended unemployment and the fact that I’m currently underemployed, I’m thinking of staying closer to home to save money, and just doing the NYMCRA kayak points races plus the USCA Nationals and Lighthouse To Lighthouse. One thing is that some of these races are far enough away that I’d really want to stay overnight the night before – I wonder if I should buy some camping equipment to save money? I’m also worried about my extended illnesses so far this year – I’ve gotten less than 13.5 hours of training so far this calendar year, and last year at this time I had nearly 55 hours.

So here’s the preliminary schedule.
May 12 – Round the Mountain
June 2 – Tupper Lake 8 Miler
June 9-10 – Madrid Canoe Regatta
July 7 – Armond Bassett
July 14 – Electric City Regatta
July 29 – BluMouLA – BuFuRa
Aug 10-12 – USCA Nationals (The website isn’t clear about what day is what, but I’m thinking of doing Unlimited and Touring this year)
Sept 15 – Lighthouse To Lighthouse
Sept 22 – Long Lake Long Boat Regatta
Sept 30 – Seneca Monster

The ones in bold are the ones I did last year. Last year I also did the “Onandaga Cup”, which was a test run for the USCA Nationals going once around the course. This year we’re doing it twice, and I believe we’re not going to start out in the lake like we did last year.

I’m thinking I might continue to use the V-12 on races where I know it’s going to be very flat, like Armond Bassett and USCA Nationals. I’m thinking about buying or borrowing a V-8 to race the Touring class at the USCA nationals. I’m also toying with the idea of maybe doing the V-8 at Lighthouse To Lighthouse to see if it means I don’t slow to a crawl in the rough bit around the second lighthouse. Either that or paddling the short course in my Sport. Otherwise I’ll stick to the Sport.

I’m hoping this will be a good year for videos. I’m going to set up a public Dropbox in hopes that other paddlers will share their videos – maybe I can make a big overview one showing multiple viewpoints instead of just my own.

Video labeling

I thought it would enhance my video if I could call out people’s names. At first I was looking to use motion tracking to have the labels follow the paddler on the screen. I tried using Motion, which comes with Final Cut Pro X, but it has two problems

  • I have to export a 10 second or shorter clip from Final Cut Pro, bring it into Motion, do the motion tracking, and then bring it back into FCP and fit it back into the right part of the timeline.
  • It really didn’t work very well – I had to keep adding manual key frames and restarting the tracking. In the video here, I actually gave up on adding more manual key frames when I was working on JoAnn’s label which is why it goes off into the weeds.

Then I tried a couple of plugins that would supposedly do the job without having to leave Final Cut Pro X. Both of them had trial modes, so I was able to experiment without paying the $100 they wanted. The first one, EasyTracker, did a pretty good job of tracking, but it crashed FCP several times every time I tried to track, and eventually screwed up the playback window so I couldn’t see anything until I deleted the plugin. The second one, CoreMelt TrackX, was practically useless. I tried putting a polygon over Jim’s bright orange shirt thinking it had pretty good contrast to the water and trees it was in front of, and said to “track forward”, and within a few seconds the polygon was somewhere off to the right of the war canoe that was to his right. Useless.

So then I had a thought – in his highly entertaining “How The Race Was Won” videos, Cosmo Catalano likes to call out riders names by using a freeze frame. He also puts a mask around each rider to emphasize it. He told me once he actually takes a screen shot and brings it into Photoshop to do that. I would prefer not to do that, not least because I don’t have Photoshop. However, FCP has a nice “Freeze Frame” feature that inserts a nice 4 second freeze of the frame at the current playhead position. Here’s what it looks like.

I kind of like this way.

My Speedstroke is at the end of its rope.

When I bought my KayakPro Speedstroke in 2011, it came with one spare rope and one spare bungee. It actually uses two of them, one on each side, but it only comes with one. I guess I now know why – after 7 years, I finally need to replace the rope. It was getting a bit ratty looking right where it goes through the front two pulleys, and it was shedding hair all over the place. But today was the last straw, as the bunched up hair started causing it to fall off the front pulleys when I was paddling easy between intervals. It didn’t take too long to replace the rope, as the whole machine is extremely well designed and constructed. And it felt so much better afterwards that I’m thinking I might just buy another rope and replace the other side as well even though it’s not showing the same signs of ratty-ness.

Backing up

Unlike some minor internet celebrities, like one of the founders of StackOverflow, I am a big believer in making sure my data is backed up locally (for quick retrieval) and offsite in case of disaster. For the Mac, this is dead easy – I have a TimeMachine disk attached to my iMac, and I back it up offsite using BackBlaze Cloud Backup – $50 a year, and it’s unlimited so it even backs up my external drive full of my iMovie and Final Cut Pro projects. I also use Syncthing to replicate several important directories between my iMac and my Linux computer. Unlike Dropbox or Box or any of the other cloud replication services, Syncthing is free and doesn’t send your data to any third party.

But I also want the “two backups” system for the Linux computer here in my office, and also my virtual private server box that I have on Linode. And unfortunately Backblaze doesn’t support Linux yet. So for several years now, I’ve been doing a local hourly backup on my local computer to an external USB drive. My strategy for that is:

  • Make snapshots of every partition on the box using
    lvcreate -L 10G -s -n ${dir}-snapshot /dev/ssd/${dir}
    (I wish there was a way to snapshot them all at once to get a really consistent view of the file system, but I haven’t found a way.)
  • Mount them all under a root snapshot so I’ve basically got a static view of the system.
  • Back that up to the external drive using rsync. I use “--link-dest” so it really only backs up the files that have changed and makes hard links to the ones that haven’t, so it’s pretty fast and doesn’t take a lot of disk space to keep weeks of backups.
    rsync -vaSH --delete --exclude .gvfs /mnt/snapshot/ --link-dest=$PREV/ $DEST/allhats2/hour$HOUR/
  • unmount and lvremove the snapshots file systems.

As well, once a day I backup one of these snapshots to a third Linux system I haven’t mentioned yet. A while ago I discovered a company called Kimsufi that was advertising VPSes with Atom processors in Ireland or France (I’m actually not 100% sure which). Nothing too fancy in the CPU or RAM department, but with 1TB of disk space for 10 Euros a month. Not as cheap as Backblaze, but better than losing everything if Linode burns down. So once a day, I copy one of my hourly backups (still using rsync with the --link-dest option so multiple daily backups don’t take up much space, and I also backup my Linode the same way (except there’s no way to take a lvm snapshot inside the VPS so it’s just a simple rsync --link-dest of everything.

That’s been kicking along nicely, and it’s a good backup. But it’s brittle – if an hourly backup fails part way through and try to do an --link-dest the next hour using that one, I can end up with two full copies of the backup with no hard links. And there are other problems as well. Plus keeping the Kimsufi VPS just to back up to seems like a waste.

A while ago, a friend recommended Borg Backup as a better solution for regular backups than trying to roll my own. It also encrypts and compresses the backups. So I set up a parallel hourly and daily backup using Borg. The offsite one is still going to the Kimsufi VPS, but it is faster than rsync. So I was just about to pull the plug on the rsync backups and go to an all-Borg solution when that same friend then recommended Restic. Now Restic resembles Borg in a lot of ways, but it’s not very well documented. But one thing it does have is that it can backup to Amazon S3 and Backblaze B2 cloud storage. Doing some quick calculations with the B2 calculator, I think I can do my backups for way cheaper this way than maintaining a VPS in Ireland – like on the order of a dollar or two a month, rather than 10 Euros. The only problem is getting it to work.

And here’s the problem. Doing hourly restic backups to my local machine are pretty quick – about the same time as borg takes. The only problem comes when I want to delete yesterday’s hourly backups (or rather apply the rules to keep 24 hourlys, 8 dailys, 4 weeklies, and 12 monthlies). With borg, I apply these rules every hour when I back up because they’re quite fast. But they’re so damn slow with restic that had to start only doing it once per day – it takes just a few seconds to run the “forget” command to apply the rules and have it forget about the snapshots that it doesn’t want, but to run the “prune” command that actually reclaims that space, it takes over 30 minutes! And that’s on a local file system. I’m afraid to see how long it’s going to take on the B2 file system, and whether it bumps up the storage costs terribly.

I also had a bit of a teething problem with my first backup to B2 – I was doing it over a network link, and I forgot to do it in a tmux session, so when the network connection got interrupted, it left my first backup in a strange state. I did another full backup the next day, and then I was using twice the required storage on the B2 bucket. I did a restic prune which reclaimed the space, but it took 35 hours to do it. That’s not going to be useful. I need to do a couple of non-failing B2 backups and see how long prune takes in those cases – but if it’s going to take hours, I’m going to ditch restic and go back to borg to the VPS.

Oh, another thing I should mention about restic – It puts a ton of files in ~/.cache. Since I was backing up from the root account, I ended up having to resize my root partition from 4GB to 14GB just to accommodate all the cache files. Very annoying. Borg has 259MB of .cache, and restic has 7.4GB.
