Nuphy Air75 v2 micro-review

After several years with a traditional full-height mechanical keyboard with clicky blue switches, I no longer want to annoy people in online meetings with the noise, and I missed the flatter profile of Apple’s keyboards. A brief perusal of popular recent reviews led me to the Nuphy Air75 V2 low-profile mechanical keyboard, with the “Moss” higher-spring-weight tactile switches. So far this is a big improvement for daily use. The feel is almost as nice but the sound is greatly reduced. It arrived already set up for Mac use, but with a handful of keycaps to swap out for PC use. It is VIA compatible, which I will use when I eventually get too annoyed with its incorrect layout of the rightmost column of keys. Overall, this is a great choice for a low profile mechanical keyboard at a middle price point.

“Personal News”

Do we still call it “personal news”?

After ~22 years, I’ve left the company I founded in 2001, and the other I cofounded more recently. I’m briefly retired (!), but likely back in the game in 2023.

My contact information at my old work… no longer works. Personal email shown in the ridiculous image below, to foil spammer-scrapers in text.

Tremendous thanks to everyone I’ve worked with in the last couple decades!

Reposurgeon, for high fidelity source control system migration

The best time to blog about something is when it happens. The second best time is when you remember years later that you should have blogged about it. That’s now.

I’ve worked on complex source control system migrations, moving between various systems, most commonly SVN to Git. There are hundreds or thousands of tools and scripts around the Internet suggested for every plausible migration pair; almost all of which don’t even attempt to solve the whole problem.

The closest I seem to solving the whole problem is reposurgeon:

The strength of this tool is that it is intended to be scripted. Rather than doing a single-shot conversion, the workflow is:

  1. Attempt the conversion
  2. Study the results
  3. Tweak the conversion script (which can perform extensive and complex changes to the source code history on its way through)
  4. Repeat until approximately perfect

Teams using an old system continue doing so while the migration is worked on. Only once the migration has been perfected, is it time to cut over.

By scripting, I don’t mean that you, the user, must write scripts to do the basics of source control system history migration; that is the job of the tool. Rather, script to patch up the ugly bits of history in an old system during the translation. For example, in a moment of desperation, did somebody once merge a giant change to the mainline, something like rolling back the last three months of development, to try to get a deployable old build? That’s an easy bit of the old history to leave out during a reposurgeon-powered migration.

During migration you can translate usernames, branch names, details buried inside commit messages, and any other aspect you might wish to clean up programmatically. Think of it as a multi-source code system compatible analog of git-rewrite-branch, except for an entire repository, not a branch.

One major downside, as of the last time I used reposurgeon: it operates in memory, so you’ll need enough RAM for the whole source code history. This can typically be accommodated, even on quite large code bases, by temporarily allocating an extremely large compute instance on your cloud provider.

A dip in the stream

After reading articles about the large and growing popularity of “streamers” on Twitch and YouTube, I wondered what all the hubbub was about. So over the last few weeks, I have dipped into several dozen streams. Mostly on twitch, a little on YouTube. I mostly look for software development/live coding streams, but also watched a few musicians, something that resembled a talk show, a broad category called “just chatting”, several gamers, and a streamer who streams about streaming. I clicked into some popular streams (thousands of viewers) and some with a single digit number of viewers.

Microsoft Teams for online classes?

Where I work at Oasis Digital, we teach a mix numerous (mostly advanced, developer-oriented) workshop classes. Historically these were mostly in-person, since March 2020 they are all online for obvious reasons.

For online sessions we’ve used various meeting tools, including Zoom, Google Meet, Blue Jeans, and others I’ve forgotten. Sometimes a customer’s IT department has our default choice blocked, we are always on the lookout for alternatives.
