The struct can be optimized but if we keep growing it with our features we hit the same problem for the cache line sequential access.

Smaller structs help with keeping working set down though.

Is there a design dock or explanation about how it can do incremental linking?

It's evaded other linkers in the past: gcc, llvm, mold etc....

I miss my Dragonfly I am a big Linux proponent but that Chromebook had me convinced about the platform. Amazing integration.

I'm at Meta now but I was at Google as well. I really enjoy contrasting the two toolchains and where they rise and fall short of each other.

I must say the debugging experience at Meta has been spectacular.

I liked the way CitC exposed Snapshots and easy to make projects.

(+ A bunch of other dozen opinions)

I was also at Amazon circa 2011 and it's funny to think about the experience back then. I remember i toiled to get Eclipse CDT to work whereas everyone else worked without any language intellisense. The work paid off though and I was able to drop P95 of the real time service I was on by 50% with the aided code intelligence + hooking it into callgrind.

Could have been a B corp perhaps

This is cool. Going to see if I can use it at work.

The hardest part is near the end for me.. I had a paper rejected and I thought I would have to extend my graduation.

When things went smooth (accepted paper) I tried to roll that motivation forward as much as possible.

My kids now are 7,5,2. They were obviously younger when I was doing it.

2 years was during COVID so I never really had to travel for classes which really saved time.

I did most of the coding and ideation on either paternity leave or holidays. Evenings were often running smaller experiments or eventually endless iteration of a paper.

My wife was great and helped me focus usually 8-11pm most nights and some weekends 1-4pm.

We don't live nearby any family and friends were not much help.

I finished a PhD while working full time with 3 young kids. Feel free to reach out if you've been interested and I can share my experience with you.

I enjoyed writing an article for this issue.

I highly recommend it if you enjoy writing. It was painless and fun.

A nice break from writing blogs.

How do you know what the equivalent C is for the JIT assembly ?

I see.

Also "containers" always had the option to attach durable storage via bind mounts.

I still get confused by the "this isn't containers" but it's kind of similar.

Maybe I am just too caught up in semantics.

A VPS that is instant to boot, super simple automatic routing and https proxy, with snapshot and durable is a win regardless.

On one hand it sounds cool. On the other, I feel like I missed it.

Is this just a fancy VPS like digital ocean with, https endpoint, snapshot and restore?

(Same thing goes for exe.dev)

but for x86_64, as of right now, if only a single call needs more than 31bits you have to upgrade the whole code section to large code model.

BOLT AFAIU is more about cache locality of putting hot code near each other and not really breaking the 2GiB barrier.
