Common tropes in software for this:

* Switching from polling to push or vice versa

* Merging two overlapping systems into one

* Splitting one system into two

* Rewriting from language X to Y

* Moving from centralized to decentralized or vice versa

* Moving logic from one layer to another (eg smart client vs thin client)

+1 I am currently reading this. It’s dense but very clean.

This is a more or less solved problem in MySQL with pt-online-schema-change [1] which accomplishes “create a new table ...” with the “copying data over” done for you using triggers and “switch clients over” done using a table rename, all within a tool with the longest full table lock held during the rename step. Some of this appears to be available in MySQL itself as of 5.6, but regardless all of this is fraught with edge cases.

Self improvement: reading and writing math, coding, and playing Starcraft.

Are you saying no downtime is impossible or merely expensive?

Erlang/OTP with relups is an example of a system that provides zero downtime online upgrade and rollback with zero downtime.

As an employee that sometimes screens resumes, LaTeX is a plus.

Figuring out why can be avoided if you have proper change management. If you are root causing every issue then that will drastically increase TTM. Instead mitigate first and just revert the change.

Mitigate first. If you are confident in your change management system then rolling back is always safe.

Simply encrypt the data and upon “deleting it” instead delete the encryption key. This is similar to concerns about backups.

This is just a failure in change management. They detected the issue in 4 minutes but it took over an hour and a half to mitigate?

That certainly was/is my initial bias.

Article states that the board needed an incentive to keep the CEO on since he was going to retire at 65 otherwise. Wasn’t this an entirely foreseeable outcome? I mean what will be different next year for example? I looked for some market force or exigency that would force the board’s hand but didn’t see any in the article.

Erlang stands out for me as having a state machine library in the standard library (gen_fsm).

Some is taught in school. I thought the MIT OCW lecture on performance [1] was extremely well done.

What about Gemini?

For fun, this exercise can also be applied to the latest crypto currency exchanges.

Websockets are also bidirectional.

Do you think legal writing falls into this category?

Isn’t it misleading to say Reddit is backed by YC now?

> reddit has had a long and complex history, starting as one of the first Y Combinator companies, then as a division of Conde Nast, and three years ago spun out as an independent entity.

Then they raised 50M in 2014.

Maybe it is different in other circles but as a software engineer, bricked still means you unplugged it while flashing the ROM, literally unrecoverable.

It's not wrong, but think of it this way: if you short a stock, your downside exposure is unlimited because the price can go arbitrarily high, but your upside is finite because the stock can only go to zero. In the same way, you can only decrease your spending so much, even to zero, but you can increase your income by an unlimited amount.

Coinbase is a U.S. company. Perhaps a small claims suit (if applicable) or a lawsuit will get their attention.

They already do this but instead of a CAPTCHA they require a SMS. I don’t know if they had the option to enter a CAPTCHA instead?

Basho is in receivership, close to bankruptcy. https://www.theregister.co.uk/2017/07/31/end_of_the_road_for...

In 2016, 4.9 percent of U.S. households (6.1 million households) had very low food security, essentially unchanged from 5.0 percent in 2015. In this more severe range of food insecurity, the food intake of some household members was reduced and normal eating patterns were disrupted at times during the year due to limited resources. [1]

What if it’s a cash equivalent like Amazon gift cards?

It’s the headquarters of the FCC.
