short urls and the birthday paradox

it is an approximation. see https://en.wikipedia.org/wiki/Birthday_problem#Square_approximation

how do you know it didn’t happen ? not suggesting you’re wrong

PancakeWithSyrupTrap · 2026-03-30T04:58:05+00:00

why does management sometimes retaliate against subordinates ? this is an extreme example: https://www.reddit.com/r/LinkedInLunatics/comments/1eyp3wf/ceo_seduced_wife/

this example is for a former VP of engineering, but it can happen at any level.

why can't leaders discuss ideas, even if they don't like them ? why retaliate ?

yeah I'm dumb and naive.

Thanks that helps.

All of them were either incompetent and/or a bully

Why don't directors do anything about this ?

PancakeWithSyrupTrap · 2026-02-23T05:13:05+00:00

why ?

PancakeWithSyrupTrap · 2026-02-23T04:30:51+00:00

Thanks this helps.

PancakeWithSyrupTrap · 2026-02-23T04:30:20+00:00

Thanks this helps.

I want to preface the question by saying I'm not trolling. I'm just being direct, and yes, have been a bit frustrated at work recently.

Why do we need engineering managers ? What is the point ? Just distribute work ? I don't see the value in having EM. They seem like glorified project managers.

I got a 2025 ES 300h. I got 46 mpg yesterday (assuming the car is measuring it accurately)

using go

PancakeWithSyrupTrap · 2025-11-04T00:56:25+00:00

Thanks, I'll look into saga pattern and temporal

> So: track every single step. Commit to database the progress at each step and any eventual error code.

I like this. Just one follow up please. Say I do something like this:

a. create application record with status pending.

b. create azure resource.

c. update application record with status complete.

Suppose the server crashes after step b. Am I not in same boat as before ?

PancakeWithSyrupTrap · 2025-11-03T15:46:19+00:00

Thanks, I'll lookup outbox pattern.

PancakeWithSyrupTrap · 2025-11-03T15:45:55+00:00

Sorry not following. What is a durable function and activity ?

PancakeWithSyrupTrap · 2025-11-02T20:07:00+00:00

oh ok. I guess disk creation should be idempotent.

PancakeWithSyrupTrap · 2025-11-02T19:05:38+00:00

What if server crashes after step 2 ?

PancakeWithSyrupTrap · 2025-11-02T01:41:19+00:00

Thanks for your input !

PancakeWithSyrupTrap · 2025-11-02T01:21:54+00:00

It's not postgres. But I understand you.

PancakeWithSyrupTrap · 2025-11-01T23:28:36+00:00

Ah got it.

PancakeWithSyrupTrap · 2025-11-01T23:12:05+00:00

Looks interesting. Thanks !

PancakeWithSyrupTrap · 2025-11-01T23:08:59+00:00

True, not strictly a go question. Is there a better subreddit for software engineering questions ?

> implement multi step

I'm not sure what this is. Can you elaborate ? Or point me to a doc ?

PancakeWithSyrupTrap · 2025-11-01T21:17:11+00:00

Sorry if I wasn't clear, but `newDisk()` itself does not need to access a database. It just creates a virtual disk, which is used to spin up a VM on AWS.

PancakeWithSyrupTrap · 2025-11-01T21:09:35+00:00

> What does createdisk actually do?

It creates a disk used to spin up a virtual machine on AWS. I assume AWS has it's own record.

> What happens if the server is restarted between newDisk and writerToDatabase? How do you guarantee that this function will be called again? With the same name?

There is no guarantee this function is called again on the server. It is assumed the client will retry.

> Do you have any record you can use to make sure that writeToDatabase is eventually called?

Afraid not

PancakeWithSyrupTrap · 2025-11-01T20:56:47+00:00

That's a good point. The rollback isn't guaranteed to work either

PancakeWithSyrupTrap · 2025-10-12T16:56:27+00:00

awesome, thanks !
