We've seen the wheel re-invented many times and would prefer to work on something other than the wheel again. Stuff like solving user problems and making money.
Meanwhile you have the coworker who uses some new but soon to be deprecated language/framework on every project, leaving a field of unsupportable debris in their wake..
Turns out brand new stuff doesn't always survive, and even if it does you don't know its tradeoffs & pain points yet.
Everything is perfect & bug-free when it has no product use.
Seen it many times, and seen the wreckage later.
If you want to be successful in your career, when you are put in charge of a big new project, on a tight timeline, high management visibility, etc.. you dig into your existing tried & true toolkit to get the job done. There's so many other variables, why needlessly add more risk no one asked for?
But yes, I'm glad there are maniacs out there.. I just don't want to work with them.
Contrast this with frameworks that are created for the framework's own sake, hoping to attract its first application developers.
Haha. Yes. But when the c-suite is made up of top level management pushed out of the s&p 500, they always assume it’s their tried and true toolkit from another company. Believe me, it’s never the hammer the current engineering staff is holding. I’m slow clapping so hard for the business school graduates right now…
However, I can't count many companies I've seen decide to get into "the cloud" only to do lift-and-shifts and are now running their stack in slower and more expensive ways.
There's a reason this youtube video exists and it's because people get into hype and then are saddled with technical debt: https://www.youtube.com/watch?v=b2F-DItXtZs
Over the last decade I worked for a fintech that did analytics for the investment banking industry and between 2016-2020 the amount of people that were shocked we weren't trying to shove blockchain somewhere was surreal.
I’m pretty sure the majority of HN thinks that even hosting directly on EC2 is for NIH adventurers only.
Depending on the project, it might actually be the only sane option if you're still required to make significant changes to the application and features have be be continuously added - and the project has already become so full of technical debt that even minor changes such as mapping an additional attribute can take days.
As an easily explained example for such: I remember an angular fronted I had to maintain a while ago.
The full scope of the application was to display a dynamic form via multiple inputs and interdependent on the selected choices of the available form (so if question 1 had answer a, question 2+3 had to be answered etc).
While I wouldn't call such a behavior completely trivial, on a difficulty line it was definitely towards the easy end - but the actual code was so poorly written that any tiny change always led to regressions.
It was quite silly that we weren't allowed to invest the ~2 weeks to recreate it
Another example that comes to mind is a backend rewrite of a multi million PHP API to a Java backend. They just put the new Java backend in front of the old API and proxied through while they implemented the new routes. While it took over 2 years in total, it went relatively well.
But yeah, lots of Greenfield rewrites end in disaster. I give you that!
You are describing a web form.
If something is a 2 week rewrite, write it in BASIC, write it in a language you invented, whatever, have fun.
Their next example was exactly what you asked for, 2 years rewrite.
Bonus points from me because they didn't wait for the whole rewrite to be done, and instead started using the new project by replacing only parts of the original one.
Building the bridge between the old & new, replacing piecemeal, and maintaining service to users the whole time.
I'm convinced on hindsight that we could have just refactored in place and been just as well off. Sure there would be some code that is still the ugly mess that made us jump to the big rewrite in the first place. However we would have had working code all along to ship. Much more importantly, we fixed a lot of problems in the rewrite - but we introduced other problems that we didn't anticipate at the same time, and fixing them means either another rewrite, or do an in-place refactor. The in-place refactor gives one advantage - if whatever new hotness we choose doesn't work in the real world we will discover before it becomes a difficult to change architecture decision.
The only time it really makes sense to do a rewrite, is when either a new architecture/technology is going to be used that will impact team competency, or the team's competency has improved significantly but is being held back by the legacy application.
In both of those situations though, you could and should absolutely cut the application into pieces, and rewrite in place, in digestible, testable chunks.
The only time it makes sense to do a wholesale greenfield rewrite, is political. For example, maybe you have a one-time funding opportunity, with a hard deadline (rewrite before acquisition or ipo, etc).
We have also improved a lot as an industry. The rewrite was started in C++98 because C++11 was still a couple years away. Today C++23 has a lot of nice things, but some of the core APIs still are C++98 (though less every year) because that is all we had the ability to use. And of course rust wasn't an option back then, but if we were to start today would get a serious look.
In hindsight, cleaning up that Perl and C++ code, even where both languages stand today, would have been a much better outcome, than everything else that was produced out of that rewrite.
But hey, we all got to improve our CVs during that rewrite and got assigned better roles at the end, so who cares. /s
It depends on what you mean by "multi-decade old app".
Excel is a multi-decade old app. Windows is a multi-decade old app.
They're both still being actively developed with a lot of new and cool features added though, and that keeps it fresh.
The multi-decade old app that hasn't been touched in 20 years? It need a rewrite. And yesterday.
I suspect though, that is not what you meant.
And we need to stop all new feature work on Excel since its legacy, so give me 80% of the dev team to do above. Oh btw, they don't know the alphabet soup of stuff I decided to use, so we will also start firing them as well, as I need to hire for these special skills.
Eventually styles will change and you will have to redo the UI. This will happen much more often than the above. Your program may look very different but if you have a good architecture this is a superficial change. It may still be expensive, but none of your core logic changes. Normally you keep the old and new UI running side by side (depending on the type of program may be different builds, other times it is just a front end) until you trust the new one. (depending on details it may be an all at once switch or one screen/widget at a time)
What does that suppose to mean
To frame your argument, TIOBE ranks COBOL as the 19th most popular language, ahead of Ruby.
It's beyond useless.
This is a better list, and cobol is not even part of the top 20, while Ruby is at 9th place: https://redmonk.com/sogrady/2024/03/08/language-rankings-1-2...
https://www.rocketsoftware.com/en-us/products/cobol/visual-c...
Anyway, as soon as LLM can reliably produce executables directly, languages will lose their value, it is the new Assembly to high level evolution.
It's like I'm sitting in a meeting.
Capable people know the constraints (and perhaps write good articles about them) and they know when to break those rules.
Good engineering is making the right compromises.

The idea isn't that you can't rewrite in a new language, it's that want to do bit by bit. Don't just to the big bang thing.
The engineering team in question had proposed to rewrite an old Java app with AWS Amolify and replace their Postgres database with Dynodb. The whole thing was then ducktaped with Lambdas and spread across multiple regions. They had not bothered writing a single line of test, never mind having any kind of build and deployment pipeline.. they didn’t even have basic error reporting.
After doing a deeper dive, we discovered that engineers didn’t have a local environment but only had access to staging, however they could easily connect to the production database from local by just updating environmental variables. It turns out that one of them had forgotten to switch it back after debugging something on production from his machine and had forgotten to switch it back.. he had a background cleanup job running in intervals which was wiping data..
It was a complete nightmare, the schema less nature of Dynamo made it harder to understand what is happening and the React UI would crash every 15 minutes due to an infinite loop.
The operation team had learned to use the Chrome console and clear the local storage manually before the window feeezes..
Somewhat similarly, I feel like the boring/mature infra often gets ripped up in favor of something hip and new by a CIO who wants a career checkmark that they "modernized" everything. Then they move on to the next company and forget the consequences of breaking what was stable.
You can build a brand new Greenfield project with Java. You can also due minor enhancements on a cutting edge tech project as well.
Interviewers care about the scope of work.
I've seen many fads over my lifetime and I expect to see many more. Some fads I regret their death, while others I'm glad we saw the light and don't use that anymore.
Same as I have for people resisting it because they want stability.
It is the management’s job to handle this decision and any potential problem caused by it, period.
Promise the world, hire, build, fail to deliver, move on.
Lots of respect for any worker, management or otherwise, who prioritizes their own welfare over someone else’s profits :)
All the company has to do is change the rules of the game!
The buck stops at the top of course, perhaps unless it’s something like government or a non-profit, but even then I’m not sure.
> We’ve seen (…) and would prefer (…) making money.
You think “the youths” don’t care about making money? That’s got to be in the top two reasons why people get into coding for at least the last decade. It’s also one of the top two reasons everything is shit, too many people only care about a quick buck.
They did.
For Mongo going to postgres went great, but for complicated reasons we're stuck with Elasticache forever on our main product.
(This is a massive oversimplification, but still used rule of thumb.)
And, most importantly, lack of market availability. Nobody is going to sell you a relational database nowadays, and rolling your own is... daring. Postgres was the last serious kick at a relational database, but even it eventually gave into becoming tablational when it abandoned QUEL and adopted SQL.
But tablational databases are arguably better for most use-cases, not to mention easier to understand for those who don't come from a math background. There is good reason tablational databases are the default choice.
And most companies vastly overestimate their data, and believe it to be "big", when it could be trivially handled decades ago by server-grade hardware.
What they don’t understand is that after 10 or 20 years of this drama you start to realize how much of this new shit is a repetition of the shit the “old shit” replaced, but with new jargon. Similar Shit, Different Day. Progress is not a ladder in IT, it’s a spiral. The scenery is never exactly the same but it swings through the old neighborhood all the fucking time.
Eat your vegetables kid.
I would only agree it can be a Bus Number skill rather than an everyone skill. My point is some day there will be a new OS the kids will embrace because everything is new to everyone and it’s their chance to shine.
A customer wrote in trying to figure out why his Fargate application kept crashing. The app would hit 100% CPU usage and then eventually start failing health checks before getting bounced (rebooted)
I relayed this back to the customer who insisted the app shouldn't be spiking in CPU usage and wanted to know why. Of course being a Fargate workload there's minimal ways to attach debugging to it. You can't just spawn htop on Fargate!
Doing due diligence I fired off an email to the team that managed the infrastructure. They curtly replied
"it failed healthchecks and got bounced"
"Okay but why"
"It hit 100% CPU"
"Okay but why?"
"It failed healthchecks and got bounced"
At no point were they either willing to interrogate or even consider the lower layers of the stack. The very existence of everything below the containerized app was seemingly irrelevant to them.
After going back and forth about this for nearly a month and a half with the customer I asked my boss to add me to the "Linux" support Slack channel. Reasoning that there's got to be other greybeards in there who (frankly) knew what they were doing better than these kids.
After writing a multi-paragraph explanation of all my findings along with the customer, moments before I hit SEND I got an email
The customers app was not releasing threads properly and causing the system to reach thread exhaustion and begin context switching, a CPU intensive process that eventually would take so long that the health check probes would breach timeout and say the app was down and restart it
Saying that "Linux knowledge is unnecessary" is to put it bluntly, ignorant to the point of clownishness. Having a holistic understanding of how a system operates is invaluable
That happens, sure, but all too often these same greybeards will fail to recognize when there is a truly novel thing. So do give new tech an honest chance before writing it off as reinventing the wheel.
Turns out they work pretty good.
Don't bet your application stack on the latest flavor of this cyclical fad.
We want to get the job done and get on with our lives.
Oh, and be able to meet the changes to the requirements we know will keep coming.
Just playing the devil's advocate here. I would prefer using boring technology that gets the boring work done as quickly and easily as possible anyways, but that's because I have more fun doing other things than working.
There is still lots of interesting stuff if your company uses newest Java or newest .NET but both are „boring” in a good way so mostly stable and changes to those are incremental and progress is stable.
Heck Angular with its latest improvements in v17 and v18 is quite interesting - but counts as totally boring and stable tech. Migration to signals and standalone components is a bit of a hassle but still is rather easy.
They don't know. And they shouldn't!
I don't have any idea what kind of tooling was used to create the drill I bought, just that it drills holes and is at the right price. Same for any other number of products and services.
The person who made the drill cares deeply, as they should. But consumers don't.
Why is software any different?
You leaned too far into the joke and it undermined the point. There’re roughly three kinds of Show HN:
1. “I made this product to solve this need I perceived. I hope it does well and makes me money. Come check it out.”
2. “I had this insane idea which is funny just from the description and made it as an experiment. Let me share what was interesting about it. Oh, and here’s the code.”
3. “I made this AI NFT Data Harvesting scam and think everyone is too stupid to notice this isn’t a real product filled with fake reviews. Come click this link from this account with 80% flagged comments.”
What you described seems closer to 2 than anything else. There’s nothing wrong with those. They stimulate curiosity, which is HN’s goal.
Not sure if that’s possible when building software systems.
Because software is living, often online, has various types of your and others' personal data, and usually runs on devices that you use for other things as well. The attack surface is massive, and more often than not, accessible. (Your drill might have a way to override the safety switch by soldering stuff to it, but you need physical access for that, and the reward is minimal; if you get into Equifax' publicly accessible servers, you get lots of important and lucrative data).
You might not care that your bank's website uses some obsolete Java framework with security holes, but you will care if they use it to drain your bank account. You might not care that your recipe generator app uses an old version of Jenkins for releases and doesn't do code signing, but you will if someone hacks them and releases a fake version that installs a keylogger on your machine, or exploits a bug in their backend to ship you malware that scrapes your Pictures folder with your nudes and important documents.
And on and on and on. A piece of software not updated for years, or a phone with no security updates, or with horrible legacy like Jenkins, is a security risk you as a user have to take at least some interest in. Yeah, you won't pick your bank by their tech stack, but when you see an atrocious website with UX out of the 1950s, absurd password length restrictions, broken domains/certificates/etc., you can be pretty sure their tech stack is a disaster, and maybe, you can try to avoid them.
I lust over a lot of gear (not guitar gear, but gear), but I keep telling myself that my goal is to play, and so I focus more on what I already have than the next gadget even though sometimes it really is my bad instrument that is the problem. Sadly, despite the above, I'm not any better than the other two groups (even when my equipment is a problem, better wouldn't help much since I'm still a large part of the problem)
Never been flyfishing, though.
Easier to geek out over the gear and/or spend the cash than to do the hard work and take the time to actually, you know, do the hobby.
First, I want to see numbers to back that up. New versions bring new bugs that aren't known yet, by anyone. Old versions have older, more widely known bugs. From a stability POV, sticking with the old may be good: you know how to work around the old issues. From a security POV, that's probably bad: every script kiddie has a Burp Suite plugin to exploit it.
Second, there ain't no such thing as an immune system. You can asymptotically approach zero, like you can approach the speed of light, but it would require infinite resources to reach either.
I don't buy into the "cyber security" arguments, and frankly I consider it a grift to keep hackers employed by playing on the fears of people. The same thing as "anti-virus" software, which never really worked in real life and isn't widely used anymore.
Never say never.
The first is just blatantly irresponsible and dumb "advice", while I do agree that most of the "you need to tick this box in order to get the contract" kind of "security" software is just malware, and often worse than what they supposedly cure.
It’s dependencies all the way down.
For most businesses, credit card processing is outsourced to Stripe or similar services, and the security for that is their responsibility. Customer data is only stored on local machines with encryption. So it's very possible to architect solutions that aren't vulnerable. Unless you want to go into very unlikely scenarios.
You appreciate why that would be a problem, surely?
As for leaking private date, now you're in the territory of some hackers having access to reading RAM memory. Which I guess is a possibility, but not something that every business in the world needs to concern themselves with.
If you call your local auto dealer and say you want to buy all their cars, don't you think they have some process stopping them from just sending all their cars to your adress? A hacker could make that call, you know...
Or how about Heartbleed where the OpenSSL library had bug. OpenSSL is on the external web server and the attack could compromise server public keys. Perfect for impersonating the server. The solution was to update the OpenSSL library.
There have been browser zero days. Hacker News sanitizes input so user can’t compromise anything. But Hacker News could do an attack.
It's the boring tech of the web ui world.
The entire is ecosystem is the definition of not-boring

Well obviously you need to catch up with the times. If the 'CTO' (who has at least 5 years of experience) of my shiny new SaaS can't do a regular blog post about how clever he is solving this week's obtuse problem in version 0.3.75beta01 of this MemeDrvrUltra thing he found last month and bet the company on, is it even really a SaaS startup? And he'd be denied that multipart year end expose (crossposted to every social platform on the planet using AIoftheWeek v.五.九 to dress it up to fit) about HOW FUCKING HEROIC his team was staying up for 8 days straight migrating from MemeDrvrUltra to SuperMegaMemeblaster ("Closed Private Beta FTW! We're special") and how it almost worked because MemeDrvrUltra was at least a couple of years old and clearly not what the VCs were talking up at the last speed pitch angel event (tho version 0.4.22.beta03 did close a bunch of our tickets (what's EWONTFIX mean again?) and changed its mascot to some funny looking frog). If all you did in life is be old and lazy and boring and pick "what works" or "what's well supported" or "stuff that doesn't get me an outage call once a week at 2:45am", what's the point of even living? Really, what sort of loser wants to work at a company like that?
