To be fair, because of window size management it only takes 1% packet loss to cause a catastrophic drop in speed.
Packet loss in TCP is only ever handled as a signal of extreme network congestion. It was never intended to go over a lossy link like wifi.
Seriously though - JIRA isn’t always a massive pain in the ass. It’s just the way it’s used that sucks. Workflow restrictions so devs can’t move tickets from testing back to in progress, dozens of mandatory fields, etc.
When your tools start dictating your workflow rather than the other way around then it’s time to switch tools.
Friends don’t let friends use JIRA
I have either written or gotten a variant of every single one of these comments 🫠:
Please include the JIRA task in the commit title.
Did you run any manual testing?
Where’s the PRD link in the commit message?
Can you please split this into multiple smaller commits?
Can you combine these two commits?
Did you email Jon about this because he’s working on that project with Sarah and you might be duplicating efforts.
This should be named BarFoo instead of FooBar.
Why aren’t you using CorporateInternalLib16 that does 90% of this?
Why aren’t you using ThirdPartyPaidLibByExEmployee?
Why aren’t you using StandardLib thing you forgot existed?
All our I/O should be async.
All our hot loop code needs to be sync.
This will increase latency of NonCoreBusinessFlow by 0.01%. can you shave some time off so we can push in feature B also?
Please add a feature flag so we can do gradual rollout.
What operational levers does this have?
Lgtm - just address those comments
Locks are only held during system calls. Process termination is handled on the system call boundary.
You’re projecting windows kernel insanity where it doesn’t belong.
What the duck Microsoft bullshit is this?
There is no concept of locked files in extfs, much less inside the kernel. Resource locks and unkillable processes is some windows bullshit that no sane operating system would touch with a ten foot pole.
So to be clear: you didn’t laugh?
Older C compilers would truncate a variable name if it was too long, so VeryLongGlobalConstantInsideALibraryInSeconds might accidentally collide with VeryLongGlobalConstantInsideALibraryInMinutes.
Legend says that they used to do it after a single letter with Dennis declaring “26 variables ought to be enough for anyone”.
Red circles are deprecated in favor of teal because of accessibility requirement WIP.DOnotUSE.14.g.2025.v0.
They started from XML. There’s nowhere to go but up but spring managed to fuck even that up.

Friends don’t let friends use Java 😜
Whoosh
Seriously though, spring configurations are written in XML and you create variables, call functions, and have control flow. Effectively turning XML into a horrible twisted shadow of a programming language.
All in the name of “configurability” through dependency injection.
XML is the second worst programming language ever created by humans
$previous_job allowed us to pick. One of my coworkers had to replace his laptop, and I convinced him to try out Linux this time. I handed him the bootstrap script and he was back to working by the afternoon.
Our CEO got wind of this and said as a matter of policy everyone is switching to Linux unless they have a good reason (needing excel for financial reports is a good reason). The two new hires who had been setting up their dev environment for over a week at that point were the trigger for this.
And here I was thinking that adding timezones for mars was going to be the biggest timezone headache in the next 5 years.
Since when is immutability controversial? Linus called out the Google patches as badly designed with massive code quality issues for good reason. Theo described OpenBSDs approach to it and it is truly a simply concept with good security ramifications.
None built in from what I recall. That was from back in 2011, so it’s possible things changed since.
Reading through, it looks like retries do exist, but remember that duplicate packets are treated as a window reset, so it’s possible that transmission succeeded but the ack was lost.
I remember the project demos from the course though - one team implemented some form of fast retry on two laptops and had one guy walk out and away. With regular wifi he didn’t even make it to the end of the hall before the video dropped out. With their custom stack he made it out of the building before it went.
I’ll need to dig through to find the name of what they did.
