I accidentally created a bug that became an amazing feature at my last job.

It was for a program to read barcode tickets (we created software and web solutions for events), and to register the barcode sacnners to the computer I had to do some magic with USB-detection since it was not specified which brand the scanners would be (so no SDK would be available).

When the scanner was plugged in it would create its own thread so it wouldn't interfere with the UI of the program when it was reading/sending data.

Somehow I messed up with the thread termination for new scanners so it would accept to connect more than one scanner and it would work flawless since it was its own thread in the program.

When I tried to think out a solution for multiple scanners when planning it I got a headache and thought that's something for later. Turned out alright in the end apparently.

Me : Here's my resignation.
Boss : No need.
Me (Expecting some good words) : Why sir?
Boss : Here's your termination.

!rant

Does anyone of you know LOLCODE?
If not let me present you a simple program that displays the numbers 1-11 and terminates:

HAI 1.2
CAN HAS STDIO?
I HAS A VAR
IM IN YR LOOP
UP VAR!!1
VISIBLE VAR
IZ VAR BIGGER THAN 10? KTHX
IM OUTTA YR LOOP
KTHXBYE

You gotta love the okay thanks bye as termination :D
Check it out on GitHub

Boss refused to sing my termination latter saying he wont sign it until CTO returns from vacation (2-3 weeks)... So today i brought my freelance project to work and i work on it.. guess who is making more €/h today and doesnt have to pay for electricity

Sorry bro.

"Your termination process has been initiated ... "

Okay I'm afraid now.

I had to let go of the two people working under me today because somebody fucked up the budget. That sucked.

Working for this startup as a remote dev for last 6 months.

This month they delayed my payment by saying that they are still waiting for crowdfunding payment to be processed.

After 3 days my teamlead who recruited me quitted with 2 more people saying that its 'personal issues'

1 week later (today) I received a letter of termination saying that my contract ceases its effect after 30 days and I will receive my payment after 45 days as all service providers.

I reminded those fuckers that in contract there is a clause saying that they are supposed to pay me within 24 hours of invoice receipt (because this is not my first time with startups). Then fuckers responded that I will get paid as soon as they receive the money.

Contacted CTO today and he told me the truth. Turns out that venture capital that supposedly raised funding of around 10 million usd last year actually didnt raise shit. In the end startup did not receive this funding because VC convinced investors that this project is shit and not worth investing.

VC's plan is to starve out the startup by giving it bridge payment injections. At some point they want to buy out the startup and resell it for profit.

And here I am fucked in the ass. But for some reason im not mad at that VC because shit happens. Im mad ar startup managers who kept us in the dark for 2 weeks and dropped us like shit :)

I am really tired of broke startups and their bullshittery.

So i quit my job today, after signing my contract termination things i asked them if i could check for some personal stuff in my work laptop. and on getting there i quickly went to terminal and did a "rm -rf /"

first time i ever did that willingly, had just been reading stories. i have to say it felt awesome to tell them its now dead, that they cant check what was on it. best feeling in a long time

Fuuuuck you AWS!!!
If you have a feature called “termination protection” perhaps it should actually prevent an instance from being terminated!

But nooo, you add *one line* of text on a documentation unrelated to ec2 terminations saying that in this particular scenario, it will terminate your instance.

Eat a dick. Eat a bag of dicks. Eat all of the dicks you fucking turd munchers.
Now I have to manually enter a month of invoices from the order emails that were created. 😡

A few days ago Aruba Cloud terminated my VPS's without notice (shortly after my previous rant about email spam). The reason behind it is rather mundane - while slightly tipsy I wanted to send some traffic back to those Chinese smtp-shop assholes.

Around half an hour later I found that e1.nixmagic.com had lost its network link. I logged into the admin panel at Aruba and connected to the recovery console. In the kernel log there was a mention of the main network link being unresponsive. Apparently Aruba Cloud's automated systems had cut it off.

Shortly afterwards I got an email about the suspension, requested that I get back to them within 72 hours.. despite the email being from a noreply address. Big brain right there.

Now one server wasn't yet a reason to consider this a major outage. I did have 3 edge nodes, all of which had equal duties and importance in the network. However an hour later I found that Aruba had also shut down the other 2 instances, despite those doing nothing wrong. Another hour later I found my account limited, unable to login to the admin panel. Oh and did I mention that for anything in that admin panel, you have to login to the customer area first? And that the account ID used to login there is more secure than the password? Yeah their password security is that good. Normally my passwords would be 64 random characters.. not there.

So with all my servers now gone, I immediately considered it an emergency. Aruba's employees had already left the office, and wouldn't get back to me until the next day (on-call be damned I guess?). So I had to immediately pull an all-nighter and deploy new servers elsewhere and move my DNS records to those ASAP. For that I chose Hetzner.

Now at Hetzner I was actually very pleasantly surprised at just how clean the interface was, how it puts the project front and center in everything, and just tells you "this is what this is and what it does", nothing else. Despite being a sysadmin myself, I find the hosting part of it insignificant. The project - the application that is to be hosted - that's what's important. Administration of a datacenter on the other hand is background stuff. Aruba's interface is very cluttered, on Hetzner it's super clean. Night and day difference.

Oh and the specs are better for the same price, the password security is actually decent, and the servers are already up despite me not having paid for anything yet. That's incredible if you ask me.. they actually trust a new customer to pay the bills afterwards. How about you Aruba Cloud? Oh yeah.. too much to ask for right. Even the network isn't something you can trust a long-time customer of yours with.

So everything has been set up again now, and there are some things I would like to stress about hosting providers.

You don't own the hardware. While you do have root access, you don't have hardware access at all. Remember that therefore you can't store anything on it that you can't afford to lose, have stolen, or otherwise compromised. This is something I kept in mind when I made my servers. The edge nodes do nothing but reverse proxying the services from my LXC containers at home. Therefore the edge nodes could go down, while the worker nodes still kept running. All that was necessary was a new set of reverse proxies. On the other hand, if e.g. my Gitea server were to be hosted directly on those VPS's, losing that would've been devastating. All my configs, projects, mirrors and shit are hosted there.

Also remember that your hosting provider can terminate you at any time, for any reason. Server redundancy is not enough. If you can afford multiple redundant servers, get them at different hosting providers. I've looked at Aruba Cloud's Terms of Use and this is indeed something they were legally allowed to do. Any reason, any time, no notice. They covered all their bases. Make sure you do too, and hope that you'll never need it.

Oh, right - this is a rant - Aruba Cloud you are a bunch of assholes. Kindly take a 1Gbps DDoS attack up your ass in exchange for that termination without notice, will you?

New contract termination clause to be included in all future project contracts: "Contracting client agrees that uttering the phrase 'Your job is whatever I say it is,' or any semanticaly equivalent variant thereof is grounds for immediate contract termination. All work product and IP rights will transfer and assign to contracting client ONLY upon payment in full of contracted payment amount prorated to contract termination date."

I want to share this story and need your advise.

When I was teaching exisiting team members about git and new iOS development ecosystem. I was changing the whole ios development practices and processes that time. One of my teammates wasn’t listening, when implementing the new ios development practices and standards, he actually screwed all of the projects.

He’s been with us for 2 years and he even don’t know how to use git. He forcefully push his changes without pulling our changes first. I was so angry that I reported him to my manager to address this matter. And then my manager told me, he is aware of my teammate’s incapabilities. He said he was planning to terminate him, and he is been thinking about it for 3 months.

When the judgement day came, we were in the meeting room. My manager told us the bad news that one of us will be terminated. During the meeting he said, “I am sorry, {my teammate’s name}. You will be out of the team due to {reason of termination}. {my name} reported to me that you dont meet the deadline, you are always late with 2 weekly sprint to your tickets”. As my manager keeps talking, my teammate look at me with his eyes so angry together with his girlfriend (her girlfriend is part of mobile team, but she is focused on UI/UX).

After my manager stops talking, her girlfriend started crying and said I was the one who should be terminated. Her reason was that I keep on giving difficult tasks to his boyfriend, that’s why he is always late to report. In my defense, those tasks are not difficult, most of his tasks is just changing the color of labels, changing layouts. If you are an iOS developer you know how easy it is to change font colors, changing the layouts using storyboards. Her girlfriend keeps on rambling that I should be the one needs to be terminated.

After few days, he left the team and surprisingly his girlfriend stayed and we never talk to each other except anything about work.

I am really pissed guys. Now my teammates think I am the bad guy asking my manager to terminate anyone in the team if I feel to. I feel very very not good in my work now. I can’t function what I used to. The termination of my teammate was already planned why am I should take the blame?

Prior to a tech conference in Las Vegas, the department manager held pre-meetings (yes, more than one)
with the developers to outline their expected behavior (yes, there was an outline in Word). Since
they would be representing the company, professionalism would be expected at all times, not just
during the conference. He knew he couldn’t forbid gambling and drinking, but any unruly behavior
that could reflect badly on the company would be dealt with severe disciplinary action up to and
including termination. He wrote up very detailed itinerary, what track each developer was
expected to attend, meal times (yes, what time to get up for breakfast, meet for lunch, and time
to eat at night). First day was fine, casinos are kinda crazy so having an itinerary wasn’t the
worst idea and no one got lost. Days following however, got interesting. After the first evening
meal, everyone hit the casino as expected (too much drinking, etc..normal single twenty-something
guys do) and the manager especially had a good time.
Next, and following days, the manager could not be found in any of the ‘required’ technical tracks.
Not that they cared that much, but couple of devs decided to check out the casino, and sure enough,
there he was at one of the tables, drunk, and being very loud around at 10 in the morning.
Again, nobody cared much, manager wasn’t very tech savy, and so attending a track on C #threading
would be lost on him. It was more of ‘do as I say, not as I do’ kind of thing.
The manager kept to the itinerary, he met everyone at breakfast, lunch, and dinner, etc, but the
‘WTF’s didn’t get good until the manager was bragging about how wonderful the conference was, how
much he was learning and couldn’t wait to get back and start implementing everything he was learning.
It was such a joke, the guys would bait him on tracks they know he didn’t attend and an amazing amount
of BS could not be believed.
On the last day of the conference several decided to follow him after breakfast to see where he went
and watched him go into a technical track, just to walk back out and straight to the casino floor.
Again, around 10, he was drunk, not quite as loud until he threw up in a trash can (they said it was quite a scene).
He left to go back his room, which they suspected he took a nap before meeting everyone for lunch.
After that, they gathered his daily itinerary was:
- Get up for breakfast
- walk around and make sure it looked like he was heading to a track
- head to the casino
- take a nap
- eat lunch
- walk around some more
- head to the casino
- take a nap
- eat dinner
- head to the casino
- wash-rinse-repeat
Last day caught up with him. After about week of drinking, staying up late, etc, his body (he’s in his mid 50’s, 350lbs+, so imagine)
kinda’ gave up. Could barely walk 50 feet without needing to sit down, and the flight back was worse for everyone,
throwing up occasionally, moaning, you get the idea.
On the following Monday with the VP if IT, everyone was discussing the conference, what they learned,
what they liked, etc, the manager also bragged, yes bragged, on how tired he was because of how much
he learned and the reason why he probably caught the flu (he couldn’t hide how sick he was on the flight)
saying “When you’re in the learning zone, you lose track of time and then you are so exhausted, your
immune system is susceptible to all kinds of things.” . VP was so impressed by his dedication and
fighting through the exhaustion for the good of the company, he gave him the rest of the day off.
Other devs? No, they had to go back to work.

Elon musk has shown himself to be a terrible person, a worse manager and someone who hasn't a clue of what a code review is. A summarily fires so many people that he can't find someone to open the doors for his big in person meeting or the vet the badges. He offers 3 months termination pay or you can work 12 hours a day 7 days a week hardcore. But none of the payroll people are around anymore either. Critical subsystems have not a single engineer left to work on them. He's paranoid that employees will sabotage the software. But I think he's doing such a good job it would be impossible to tell that anyone else was helping him.
An engineer wrote a prescient seven page report listing problems ahead including user verification. So Elon twit-fired him.
Also entirely predictable is the stress that the world cup will put on the system beginning today, I believe. He doesn't "like" microservices.
I work for the psychiatrist once who barely needed to sleep. Maybe Elon can function with 12-hour days week in week out. But it's cool to think you're going to squeeze substantially more work out of people by doubling their hours. More likely you will more than double their errors and what will that do to you budget? 50 years ago IBM determined that the best way to improve programmer productivity was to give each one their own office.
I can't believe he's whining over spending 13 million dollars a year on food. That is so far from being a strategic item. Soapbox out.

Just had to write an old-skool for loop. Index...termination condition...whole works. I feel dirty.

Bit embarrassing as someone saw me writing it, thought I was a hacker and informed the authorities. Spent the last hour being waterboarded.

We had a big laugh about it when they realized I was just fixing bugs in a legacy app.

National Security. Hilarious.

So i have been working as a graduate developer in this company i joined 5 months ago with some other graduates. I was on probation and it was supposed to end in near future but it got extended because " i was not being punctual". The feedback i got was " you are technically brilliant and have done all the tasks you have been asked to do but aren't being punctual and coming late to the office sometimes ".
I am indeed at fault that i sometimes enter the office late like 5-10 mins from the mentioned range. But whenever that has happened i always made it up while working late at work, this is my first job and even though i was being funny with the manager when we were discussing this i am not so happy right now, is it a big enough reason for extension ? Do you think if it can become a reason for termination ? Some other graduates have their probation extended cause of other reasons like late task completion.

Just need to understand how badly am i fucked.

Debating on whether to quit my job.

Part of the reason it's hard for me to make a decision is there are a lot of good things about my job:

- almost all the projects we work on are blue sky; no technical debt anywhere
- great teammates; people help each other out and generally there's a good vibe
- reasonable boss; he's totally fine with me managing my own schedule, and since I get my work done, he basically never questions when and where I work
- about 1 hour of corporate meetings each week
- best healthcare I've ever had; basically everything is paid for
- 3 weeks PTO & all major US holidays
- free food; generally healthy office snacks and such

So why would I want to quit this environment?

- I hardly get to code anymore. About 2 years ago, I got asked if I would mind helping spec out projects. Since then, I've moved from writing code related to projects to helping my teammates understand the business situation so they can build the right thing.
- I'm in lots of meetings. So we have very few meetings for the company itself. We have a bunch of customer meetings, though. And progressively, I've getting pulled into meetings where there's really no reason for me to be there, aside from "we should have a technical person present."
- The sales people are getting tired of turning down clients that our product isn't targeted for. So they're progressively pushing to make products in those areas. Unfortunately, I'm the only one on the engineering team has any experience in that other tech stack. Also, the team really, really don't want to learn it because it's old tech that's on its way out.
- The PM group is continuously in shambles. Turnover there has averaged 100% annually for about 5 years. Honestly, IMO, it's because they're understaffed. However, there has been 0 real motion to fix this other than talk. This constant turnover has made it so that the engineering team has had to become the knowledge base for all clients.
- My manager has put me on the management track, but has been very slow to hand off anything. I'm the team supervisor, and I have been since the beginning of the year formally. When the supervisor quit last year, it basically became obvious to me that I was considered the informal supervisor after that. However, I can't hire or fire; I can't give a review; I don't have any budget; I can't authorize time off. So what do I do now? Oh, I'm the person that my boss comes to ask about my co-workers performance for the purpose of informing promotion/termination/pay increases. That's it. I'm a spy.

I grabbed 30 random DOS malware samples from my collection, rolled via urand over Python list, and tried to figure out how they work.

Results:

1x zipped EICAR
4x working but effectively useless ("yeah you wiped the first 100 sectors of the drive... but you wrote their prior contents. Literally nothing's changed...")
10x CPU hang
10x crashdump back to DOS
5x crashdump back to DOS but ERRORLEVEL=0 so normal termination despite real errors being given?

also make sure SOURCER is disassembling using 486 or Pentium opcodes or it misses some 286/386 opcodes and will count half the program as data.

-- Best --
> Submitted my notice of termination for my current job
> Found a new job starting next year
> Can switch from Windows to Linux/MacOS in new job
> Got more time to work on personal projects due to the pandemic

-- Worst --
> Huge amount of software restrictions (current job) almost got several projects at work canceled. Maybe its important to say that the core business of my current workplace is auditing so there are a lot of law regulations which then apply in the softwaredevelopment process.
> New managers that do not have the slightest clue of what they're doing
> Online Teambuilding events
> Absurd amount of segmentation of tools and also different coding guidelines that are used at work. E.g. one team uses jira, another trello, another github issue tracker and so on.

I need help!

This is gonna be a long question/story.

I'm a Syrian based in Malaysia working as a lead web dev in a good company.

I have a friend in trouble and I want to help him.

Here's a summary:

My friend is a project manager at a gaming studio he happens to be an Iranian atheist with around 2 years of experience in the game making industry.

He worked on and delivered a couple AAA games at his current place of employment as a project manager in one of the teams that made those games.

He stood up for his team when the management was overworking team till after midnight sometimes and forcing them to work on weekends without any tangible compensations ( basically they gave them things like free lunches, movie tickets, etc).

The result of his standing up to his team was the management handing him a notice telling him that he'll be fired within 2 months due to "underperforming".

This was a month and a half ago.

He looked around in Malaysia for a job that can get him a working visa, but his niche background couldn't help.

After his termination in few weeks he can extend his stay at Malaysia for approximately 2 - 3 months.

Now the reason why I mentioned that he's an "Iranian atheist" is the fun part of this story (sarcasm), Iranian government considers him as an "infidel" and he's banned from Iran.

His Iranian passport can't get him anywhere where he can make a living.

So basically he has close to no options.

Now to where I come into all of this:

I want to help him.

I'm going to dedicate my free time for the next 2 - 3 months teaching him web development, the problem is, I don't know how to teach web development in such a short time, in fact I've never taught anyone programming from scratch.

If he can show promising results I know that I can make a case for him get him a position in the company I work for.

I already convinced him today to try and learn web development because I can tell that in Malaysia there's always demand on good web developers.

Now to my request:

how can I best teach web development to someone with no programming background ? I'm thinking about teaching him front end development, so: HTML, CSS/SASS and JavaScript. maybe react js as well if possible ( high demand is usually on React/ Angular front end developers)

Did anyone here teach programming to someone else before?

Did anyone here learn web development in such a short time?

If you've read all this... Thank you :)

Custom SSL termination proxy with automatic certificate issuance and renewal

I'll monitor our helpdesk ticket system from time-to-time and HR will send their employee termination request so the accounts are deactivated. I notice an odd name I hadn't seen in a long while (names have been changed)

<thought bubble> "Ketsup? Hmmm...wonder if they're related to ol' Brad Ketsup?"

Brad was a bully who would shove me in the bathroom when I would pee so I would tip over and hit the urinal. He was part of pack of older bullies who enjoyed torturing people in the stalls by throwing wet paper towels over the wall or one time in my case, busted the door open (Brad: "Look everybody! PaperTrail is pooping! Look at his little pee-pee...ha ha ha..") Incidentally, the school didn't fix the door, they removed all the doors so the problem wouldn't happen again, but I digress.

I look at the individual's pic, and it was like going back in time. There he was, the near perfect round face, pinned back ears...not Brad, but I'd bet my paycheck at Vegas it was his son. All the vent up frustrations started to bubble up...then...sadness.

Brad moved away in high school and unless the good Lord moved mountains in Brad's life, this poor kid likely lived the same abusive life as Brad. Brad's dad was a drunk and known to be abusive. Statistically speaking, no reason to believe the the apple wouldn't fall far from the tree.

Makes me wonder what happened to all those guys from back then. I know two of em' ended up in prison, but I wonder what I would say if I came across any of them in the wild?

I'm sure most of you had perfect lives growing up and no feelings of mass carnage when you think of the bullies in your early life.

Disclaimer: This is all theoretical. Neither me nor my friend (with whom I discussed this) are stupid enough to even try to pursue this, but as an idea, i believe it might generate cool/new ideas/ways for handling secure communications across social groups.

Let's do some role play. Let's design a delivery app for drug dealers, think Seamless or Uber Eats, but for drugs. Not for big deliveries, like kilograms of coke, but smaller stuff. Maybe a few grams of it or something. The clients could rate dealers, and vide-versa. This would build a level of trust within the system. There would be no names, just anonymous reviews, ratings, and prices. Only the info you'd need to know.

The biggest (only?) problem we found (besides legality) was that, how would you prove that you're a client and not a snitch (or cop). This would have to somehow be handled both on signup, as well as when ordering (let's imagine that all who are clients are pure and won't ever snitch).

One of the ways we found to combat this was to have the app invite-only. This would, in theory, do away with the problem of having snitches signing up. However, what if the phone got stolen/breached by a snitch, and they also got full access to the account. One way we thought we could combat this would be with a "dispose number" or something similar. Basically, you call a number, or send a text, or message a Signal bot etc, which would lead to the account's instant termination, no traces of that user left. Hence, a dispose number.

The flow of the app would be as follows:
A client wants some amount of heroin. He opens the app, searches for a dealer, sends the him the desired amount, and in return gets back a price from the dealer. If both parties agree on the amount and price, the deal would start.

The app would then select a random time (taken from the client's selected timeframe and the dealer's "open" time) and a location (within a certain radius of both them, somewhere in between them both for convenience). If both of them accept the time and place, they'll have to meet up at said time and place.

The actual delivery could also be done using two dead drops - the client drops the money at one of them, the dealer drops the goods at the other one. Yes, this might be subject to abuse, but it wouldn't be that bad. I doubt that clients would make huge orders to unknown/badly rated dealers, as well as dealers accepting offers from badly rated clients. My idea is that they would start small, just so if they do lose their money/goods, the actual loss wouldn't be as big for them, but for the other party, having bad ratings would mean less clients willing to buy or dealers willing to sell.

A third way would be to use crypto, but the reason I left this as the last one is because it's not that wide-spread yet, at least not in local drug dealing. With this method, the client would initiate the order, the crypto would be sent to either the dealer or an escrow account, the dealer would then drop the goods at a random place and let the client know where to go to get them. After the client has gotten the goods, they could both review/rate the quality as well as the overall experience with that dealer, which would either make or break the dealer's upcoming deals. This would be pretty much like other DNM's, but on a local scale, making deliveries faster.

So far, this would seem like something that would work. Are there any ideas that might improve this? Anything that might make things more secure/anonymous?

My reason for this post is to spark a conversation about security and anonymity, not to endorse drugs or other illegal stuff.

Cheers!

PS. Really loving the new PC design of devRant

So today I did the weirdest use of REST API I have ever seen. Was working on a little electron app for a friend using angular as frontend. I didn't want to use the standard title bar so created one for me in angular. But to hookup the close button with actual termination would have required more effort than my lazy ass was going to put. So I just created extra route to use browserwindow.close() function. And it actually worked good.

C++: the Static Initialisation Order Fiasco. If you have two static instances in separate translation units, there is no way to guarantee their initialisation order, you're at the mercy of the compiler/linker. If one of the instance constructors depends on the other already being initialised, you have a 50% random chance of your program blowing up. The same ordering problem applies to global destruction at program termination time.

Do you have doomsday code? The code that executes upon your termination?

Getting ready for another day at work.

They seem to think that scrum is the perfect tool to micromanage their team.

Thanks guys for the creative ideas on how to get back on her, but I'm doing the responsible thing and I'll send them a nice email detailing why that's fucked up and what they need to change.

Adding important words like, "that behaviour is affecting team integrity" or "it demotivates people", "It is counter productive", "it diminishes team performance", "instills fear".

Maybe, or I'll stick to my work hours and wait for my contract termination notice. 🤣

Ok so a few weeks after contract termination I manage to get hooked up with another startup and jumped on a project
The grate part about this is they even paid half upfront

The moment you realize the .net Framework's String.TrimEnd() method will actually modify your String prior to returning it, and there seems to be no convenient way of getting a copy without declaring a new variable...

Just wanted to get rid of excess empty lines in the log caused by trailing <CR><LF> when receiving lines of serial data:

Console.WriteLine(DateTime.Now.ToString("H:m:s.fff") + " - serial data received on " + com_port + ": " + serial_data.TrimEnd())

But suddenly the parser could not find its termination characters anymore...
Resulting in probably the most disgusting parentheses I had ever added to any code:

Console.WriteLine(DateTime.Now.ToString("H:m:s.fff") + " - serial data received on " + com_port + (": " + serial_data).TrimEnd())

Yes, I feel bad about it, but then again is VB .net and it kinda "works for me". I promise I will (try to remember to) remove these as soon as debugging is done...

Persisterising derived values. Often a necessary evil for optimisation or privacy while conflicting with concerns such as auditing.

Password hashing is the common example of a case considered necessary to cover security concerns.

Also often a mistake to store derived values. Some times it can be annoying. Sometimes it can be data loss. Derived values often require careful maintenance otherwise the actual comments in your database for a page is 10 but the stored value for the page record is 9. This becomes very important when dealing with money where eventual consistency might not be enough.

Annoying is when given a and b then c = a + b only b and c are stored so you often have to run things backwards.

Given any processing pipeline such as A -> B -> C with A being original and C final then you technically only need C. This applies to anything.

However, not all steps stay or deflate. Sum of values is an example of deflate. Mapping values is an example of stay. Combining all possible value pairs is inflate, IE, N * N and tends to represent the true termination point for a pipeline as to what can be persisted.

I've quite often seen people exclude original. Some amount of lossy can be alright if it's genuine noise and one way if serving some purpose.

If A is O(N) and C reduces to O(1) then it can seem to make sense to store only C until someone also wants B -> D as well. Technically speaking A is all you ever need to persist to cater to all dependencies.

I've seen every kind of mess with processing chains. People persisting the inflations while still being lossy. Giant chains linear chains where instead items should rely on a common ancestor. Things being applied to only be unapplied. Yes ABCBDBEBCF etc then truncating A happens.

Extreme care needs to be taken with data and future proofing. Excess data you can remove. Missing code can be added. Data however once its gone its gone and your bug is forever.

This doesn't seem to enter the minds of many developers who don't reconcile their execution or processing graphs with entry points, exist points, edge direction, size, persistence, etc.
