When building a tool, it’s easy to forget how much you’ve internalized: how much knowledge and context you’ve assumed. Your tool can feel familiar or even obvious to you while being utterly foreign to everyone else. If your goal is for other people to use the darn thing — meaning you’re not just building for yourself, or tinkering for its own sake (which are totally valid reasons) — you gotta help people use it! It doesn’t matter what’s possible or what you intended; all that matters is whether people actually succeed in practice.

I strongly suspect that the single most impactful thing I did during my 5+ years at Linden Lab was shortly before I left: set up a weekly meeting between a couple of leads from Support and Engineering to go over the top 10 support issues.

Business rules engines are li’l Conway’s Law devices: a manifestation of the distrust between stakeholders, client and contractor. We require BREs so that separate business units need not talk to each other to solve problems. They are communication and organizational dysfunction made silicon.

One of the hardest things I’ve had to learn is that humans aren’t pure functions: an input that works one day and gets one result, then again another day and get an entirely different result.

Litestream runs continuously on a test server with generated load and streams backups to S3. It uses physical replication so it’ll actually restore the data from S3 periodically and compare the checksum byte-for-byte with the current database.

Finally, remember that whatever choice is made, you’re going to need to get behind it! You should be able to make a compelling positive case for any of the options you present. If there’s an option you can’t support, don’t present it.

Technology does not need vast troves of personal data stitched together across dozens of websites and apps in order to succeed. Advertising existed and thrived for decades without it, and we’re here today because the path of least resistance is rarely the path of wisdom.

Tuesday’s chaos arose after China Railway Shenyang failed to deactivate Flash in time, leading to a complete shutdown of its railroads in Dalian, Liaoning province. Staffers were reportedly unable to view train operation diagrams, formulate train sequencing schedules and arrange shunting plans. Authorities fixed the issue by installing a pirated version of Flash at 4:30 a.m. the following day.

When you know something it is almost impossible to imagine what it is like not to know that thing. This is the curse of knowledge, and it is the root of countless misunderstandings and inefficiencies. Smart people who are comfortable with complexity can be especially prone to it! If you don’t guard against the curse of knowledge it has the potential to obfuscate all forms of communication, including code. The more specialized your work, the greater the risk that you will communicate in ways that are incomprehensible to the uninitiated.

Generally, product-aligned teams deliver better products more rapidly. Again, Conway’s Law is inescapable; if delivering a new feature requires several teams to coordinate, you’ll struggle compared to an org where a single team can execute on a new feature.
