I definitely was. I still use one now, more than 3 years after their business failure. I really wish someone would make something like the Pebble Time 2.

I'd still use my Time Steel if the battery didn't die, and I'm afraid of breaking it and its waterproofing if I attempt a replacement.

Technically you have nothing to lose.

Frankly, I'm satisfied enough with my Pebble 2 that I'm not sure I care whether anyone makes a new one. I just hope I don't end up in a situation where it breaks and I can't get a replacement.

Unfortunately, the battery will likely fail after 4-5 years.

I have an Amazfit Bip, but the UI isn't as good as Pebble sadly. There is some work in making a similar OS called RebbleOS[1] currently ongoing. [1]: https://github.com/pebble-dev/RebbleOS Hopefully it will be portable to other low-end smartwatches.

I use rebble services, but I haven't seen much progress on the OS. I have slightly higher hopes for PineTime.

I’ve run into serious house burning down problems with myrocks too. Simple recipe to crash MySQL in a way that is unrecoverable: do ALTER TABLE on a big table and it runs out of RAM, crashes, and refuses to restart, ever. Googling and people have been reporting the error on restarting several times on lists and things. What help is it to report to Maria dB or something? But do FB notice? Seems not. Here’s hoping some…

I am one of the creators of MyRocks at FB. We have a few common MySQL features/operations we don't use at FB. Notably: 1) Schema Changes by DDL (e.g. ALTER TABLE, CREATE INDEX) 2) Recovering primary instances without failover We use our own open source tool OnlineSchemaChange to do schema changes (details: https://github.com/facebook/mysql-5.6/wiki/Schema-Changes ), which is heavily optimized for MyRocks use cases li…

Thanks for explaining this! Really appreciate that you joined in here.

We've been test running our real-time dwh etls on myrocks (and postgres and timescale and even innodb) to comppare with our previous workhorse, tokudb. We've chewed through cpu years iterating over every switch and setting we can think of, to find optimum config for our workloads.

Like for example we've found that myrocks really slows down if you do a SELECT ... WHERE id IN (....) from too long a list of ids.

So we have lots of thoughts and data points on things my team have found easy, hard, painful, better etc. I'd be happy to share with you folks.

(FWIW we are moving from tokudb to myrocks now, with tweaks to how we do data retention and gdpr depersonalization and things)

Ping me on willvarfar at google's freemail domain if that's useful!
