A while back there was a discussion about employee retention and churn, with some parties claiming a complete staff turnover over some period was a good thing, and that documentation could serve as the complete institutional memory.
I hope they read this.

Writing and maintaining good documentation is hard, which in business terms means expensive. If a company doesn’t want to pay enough to reduce turnover it likely would not invest into documentation either. And even is it will no documentation would quickly turn a novice into a seasoned expert.
MathMonkeyMan 7 days ago [-]
Three problems with documentation. Sometimes it doesn't exist, sometimes you can't find it, and sometimes you don't read it.
Well I guess the fourth problem is it could be wrong, but that just comes with the territory.
MichaelZuo 7 days ago [-]
There could be a fifth problem too, it shouldn’t be referenced.
Because it was compiled incorrectly by someone/some group without sufficient permission to do so, so referring to it would lead to corporate politiking.

> My job now was to smuggle these documents back into the company. I would be happy to just hand them over. But that doesn't make any sense to the company. The company officially has these documents (digitally managed!), and officially I don't. In reality, the situation is the reverse, but who wants to hear that? God knows what official process would let me fix that.
This is beautifully written :-D

At least the company hired him back as a consultant with a big paycheck.
It's ironic how managers and executices in organization, especially but not limited to companies, are always stressing about the clock for a few minutes lost here and there by employees, yet are totally fine wasting days of productivity by not having a proper documentation process or practices.

We will be seeing this with nuclear soon. The only people I know that studied nuclear engineering or related fields are in their 60s. The renaissance of nuclear will put these people in high demand and a fresh cohort of young people will be drawn into it.

> The alien machinery hums along, producing polymers. [...] The more I look around, the more the engineering world, once you go back more than a few years, looks like subterranean New York City. A mass of strange engineering feats humming away out of sight, produced by long-forgotten ancient peoples
These sentences made me think of the game Factorio. For those who don't know, in the original game (before the recent Space Age expansion) the official objective was to build and launch a rocket, leaving behind the still running automated factory which produced the parts for that rocket (and yes, one of the intermediate products is polymers, simplified in the game as "Plastic"). One can imagine someone, much later, encountering the long abandoned factory, still running and still producing polymers.

I wish there was a game that did this on purpose. You are given an undocumented alien half-broken contraption and your goal is to repurpose it for something different.
Space Station 13 was a little bit like that sometimes.

If someone wanted to be such an archeologist but instead for figuring out how some code or project worked (where perhaps the only remaining thing was the compiled code and some limited documentation), what sort of role/position would that be?
To my mind it just seems like something one would get assigned or throw into when looking into improving a process similar to the company in this story, but perhaps I am missing something.
btrettel 7 days ago [-]
In "traditional" engineering, there are a lot of old code bases still in use that few people (if any) have a solid understanding of. I've seen code comments dating to the 70s. Often the code was "documented" in internal reports. Many of these reports are now lost. These reports are often incomplete or unclear when they can be found. Plus, what you read in the ancient reports may not be current.
The job ad will probably not directly say anything about code archaeology. If the job ad mentions some sort of in-house simulation software, and the organization is 50+ years old, I'd say it's a coin toss as to whether you'll have to be this sort of software archaeologist from time to time.

If you're a strong technologist, ideally with some reverse engineering experience, and you befriend a bank CTO, you will probably be offered a job that is part this and part saving projects that are trying their best to jump off a series of cliffs.
Just make sure to set it up as a consulting gig and never, ever, work for a bank.

Go work a normal engineering job for a bank or government on something close to whatever was the core system 30 years ago. You should see the signs when you get close enough.

My only-mostly-joking answer is that you can go work for a typical Silicon Valley style technology company, and stay around for two or three four-year vesting periods. Most of them have Google-influenced design doc processes, and few if any have a process for documenting what actually got built, much less what it eventually turned into.
One of my hobbies is feeling dumb for not understanding something, being willing to ask, realizing _nobody_ knows the big picture, and trying to document it.
tbh though I have also occasionally fantasized about finding a job that was _only_ software archeology.
Lol, NASA literally left an instruction manual on how to go to space, and return safely. The contributions those folks have made over the years is related to just about everything you depend on these days.
People just choose to ignore the documentation, as there is less political mileage in throwing money into space these days. =3

Some git repos were ported over from SVN repos that were migrated from CVS. I never migrated anything into CVS, so I don't know if that was common at the time. But there are a lot of git repos out there with commits older than git itself (the Linux kernel itself I'm sure is the most prominent example).

That's true actually, I'd forgotten about that possibility. I believe that FBs monorepo was originally in Subversion and that codebase turned 20 this year.

I did migrate several projects from tarballs to RCS, and then a decade later to CVS. The biggest thing back then. Renaming dirs and files directly on the central server. Good old days.
Several embedded colleagues still work on pre-tarball workflows though: zip files and word documents.

> But there are a lot of git repos out there with commits older than git itself (the Linux kernel itself I'm sure is the most prominent example).
No, the official Linux kernel repository is only as old as git itself (being one of the first three projects using git, the other two being sparse and git itself); the older history of the kernel was deliberately not imported into it. There are later repositories which did import the previous Linux kernel history from Bitkeeper and older tarballs and patches, using mechanisms such as graft to tie together these historical commits and the new ones, but the result has never been part of the main repository.
neallindsay 2 days ago [-]
Yes, I was talking about the unofficial "historical" repos, not the official git repo that everyone works off of. I should have been more clear.
>Unfortunately, the internal team doesn't know what the secrets are, while I do. I even invented a few of them, and have my name on some related patents.
I'm confused about how something can be both a secret and patented. Isn't the point of a patent that it is public and no longer secret?
btrettel 7 days ago [-]
I was confused by the same thing. I guess that the patents are only related, and don't actually contain the trade secrets.

That's the game. Put in enough detail to get the patent but not enough to actually implement the invention.

This is something ive seen at three defense companies ive worked for. They will toss the new hires in bad times but hang onto the old timers and let them do as the please. The rto never applies to them and they horde like smaug. The best job in defense is to be one of these. Boeing made lip service to passing on knowledge but when it came to true core ppl they were never part of the process.
