What we can’t know is whether they would have been fast enough to tweak their product to their current market without using a scripting language. Companies who do that aren’t sacrificing performance for nothing, scripting languages make a lot of things simpler and closer to the business domain, which cannot be ignored (anybody who’s in a huge project that requires a 30 min. compilation often enough to kill productivity knows what I’m talking about).
Besides, you can even use optimized C and get none of the benefits (but still all the drawbacks) because of the algorithms you’re using or your database or something else entirely such as microsservices etc. making differences in language speed negligible.
I guess the point is the language speed on backends don’t matter as much as many other things (network, database, architecture setup etc.) and usually the gains you get with your language being faster aren’t high unless you’re in a tight loop or you’re like Amazon where even a few milliseconds gain is more money.
> What we can’t know is whether they would have been fast enough to tweak their product to their current market without using a scripting language.
Exactly. And I am saying the following as a fan of dynamic languages but let's be realistic: this is practically their ONLY true benefit -- quicker time to market. They lose out on pretty much any other metric, with the exception of also slightly quicker iteration in the day-to-day work.
True, though I've measured my time to prototype with different languages some months ago and the advantages of PHP / Ruby / Python are oversold.
- Ruby on Rails prototype: 2.5 days.
- Golang's Gofiber: 4.5 days.
- Elixir's Phoenix: 7.
- Rust: don't ask (too long lol).
- Python's Django (made by a friend): 3.5 days.
Not to split hairs here but if you are in a situation where 5 days more for a prototype matter then I am not very sure you would have succeeded even short-term after. Putting your foot in the door can be extremely important, absolutely, but after whipping out a quick MVP you'd likely immediately stumble upon the next obstacle which is not guaranteed to be overcome.
As mentioned in my previous comment, the only argument in favor of the fastest-to-prototype languages could be that they allow slightly higher velocity day-to-day as well. But I've worked with PHP and Ruby for a long time, and I've worked with Elixir, Golang and Rust for quite a while now as well and again, that particular advantage of PHP / Ruby / Python (a) does exist, yes, but (b) is not as big as people make it out to be.
So, wait, all apps are trivial in nature and can be built in less than a week?
By your own admission here GO takes nearly twice as long (which is about what I've seen). So if you aren't building a trivial app but instead building something that takes 6 months in Ruby you'd be spending nearly 12 months in go. Sounds like a real significant amount of time if you are rushing to get to market.
Why resort to a straw man? There are plenty of options between "a language that does not even have strong types" and "machine code"? E.g. Elixir is strongly but dynamically typed and you can take it quite far while reaping most of the benefits of typing and not losing velocity as you would with many statically strongly typed languages.
Nuance matters. I wouldn't pick Ruby for anything except scripts nowadays. You get absolutely zero guarantees and being able to whip out an MVP in 2 days is not as important as people make it out to be. Extremely often being able to have an MVP in 10-20 days is just as viable but then you will have to write less tests and have more guarantees from your compiler.
> You wouldn't pick Ruby, thats your choice. People are still making billions of dollars with it.
Not arguing with their results here. I am saying that they made it work despite how terrible it is. You have no guarantees about anything and you have to have much more tests than you would have in other languages just so you have basic stuff ensured. Not cool at all and I am saying this as a guy who made good money with Rails for 6.5 years. Not impressed to this day and I am happy I left it behind. It's good for scripting I'll admit, though nowadays I just learned bash/zsh better and use Golang for the same task occasionally.
> what language should they have used 17 years ago when they started the company?
Whoops, you are 100% correct that I ignored the historical timeline (Elixir didn't exist back then, yes), sorry about that, I derped big time.
That being said, all of PHP, Ruby, Python, Java and C# were indeed valid choices back then. But I've been part of successful rewriting efforts (biggest one was about 270k coding lines which I'll admit is much smaller than what Facebook and other big corps are dealing with) and to me the downsides of rewriting are overplayed:
- You need extensive tests? Well, you need them even if you never rewrite.
- You will now have two systems? So what, you already have a load balancer, you will just put a few more rules in it.
- Hard to find engineers for $new_language? That's true if you do it in its first 5 years of life but I've been part of growing ecosystems twice (Elixir and Rust) and it only gets easier with time. Solution: don't be a super early adopter, that's obviously too risky. E.g. both Elixir and Rust are beyond 10 years old at this point and are now a safer choice.
- Have to duplicate the old system's bugs? Tough nut to crack and I partially agree with this one but what my previous teams did was write down these bugs in the docs and made sure to start fixing them after the rewrite was completed. And in all cases fixing the bugs in the original language was planned anyway but was eternally kicked down the road.

My main point here is that it's OK to admit at one point that the tech you used for a while has outgrown its usefulness. I understand and recognize some of the downsides but to me they are overblown.

My entire complaint is just that you want to say it's outgrown it's usefulness. That is such an absolutist view. And the fact you are even bringing rust into this is crazy. I know C, C++, ASM, GO, and a few other low level languages. Rust is harder to learn than all of them, even ASM. And Rust in some ways can be a dumpster fire when you have to unwrap everything. A very intelligent person can take months to be comfortable in Rust or be similarly comfortable in GO in a couple days.
It's such a dogmatic view to say Ruby has outgrown it's usefulness, that's fine though you are entitled to it. Ruby isn't going away, it'll still be there and I'm sure people will continue to make money with it.
I just realized we're chatting in 4 separate spots, heh. So let's unite them.
> My entire complaint is just that you want to say it's outgrown it's usefulness. That is such an absolutist view.
I don't speak for all programmers and IT companies -- and neither do you. We are both right at the same time due to the fact that the world is big.
I've been in super small teams (think 3 people) all the way to 50+ and stricter typing is more and more sought after the bigger a team becomes. It's very hard to code confidently the weaker the typing of the language is after a project gets beyond a certain amount of coding lines. Every dev must spend extra time to self-onboard in the context of others' work before being able to meaningfully contribute.
Of course this curve tapers off eventually and some teams become super well-oiled machines -- that's a fact. But we don't live in an ideal reality; people leave, some get sick and are gone for 2-3 weeks, others get reallocated to other projects. Things happen and the ideal stable-ish state of a team is rarely achieved.
Having stronger stricter typing gives peace of mind when coding. It does reduce prototyping (and sometimes the day-to-day) speed but from one scale and up it is worth it and that cost is quickly surpassed by confident and quick delivery of features or bugfixes in the mid-term.
> And the fact you are even bringing rust into this is crazy.
Oh I agree. Rust can be infuriatingly hard and slow to progress with. I've made the mistake to try and prototype one thing with Rust and I lost one small business opportunity because of that. Won't ever do that again. Believe me, I've experienced this craziness first-hand and I agree with you there.
> It's such a dogmatic view to say Ruby has outgrown it's usefulness. Ruby isn't going away, it'll still be there and I'm sure people will continue to make money with it.
Maybe it's dogmatic to you because you imagine that if I was right Ruby would be no longer widely used and since you are not seeing that, you thus think me wrong? Well if so, (1) the world is big and even if Ruby is being gradually shown the door it can take decades until you and I notice, (2) your assertion that Ruby is not going anywhere is 100% true but does not contradict anything I've said because there's a place for everyone in the IT sphere and that still does not mean people are not seeing cracks in Ruby's perfect image (people from Twitter and Shopify have expressed displeasure with it a good amount of times in the past... and now I regret I never kept the archive links because I always get asked for source and can no longer provide it -- sigh).
BTW many people came to Elixir from Ruby and said they're never going back unless they have to build an MVP in a weekend -- they would go back only for that.
> Maybe there wouldn't be a product at all with GO or Elixir. It's hard to say.
I am not claiming either way. Don't imagine me such an extremist, please -- I am not. I am only saying "OK you did it with PHP, Ruby or Python, the tech did the job okay-ish but it's beginning to suck for you -- why are you so averse to admitting that it's time for a change?". I got a very cynical answer and at the risk of you thinking me even more extremistic I'll name it: a lot of programmers love cozy jobs and they might hate what they do daily but they still love the wages and are not gonna rock the boat. Obviously I can't claim any percentages but I've been around and I've met plenty of such guys and girls. So IMO you should factor that into your analysis.
Inertia and network effects do exist and sadly they often have nothing to do with the quality of the thing they are carrying (think of all the sucky software we all must use if we want to communicate with others -- that's a good example of inertia / network effects not being correlated with the quality of software).
> We can disagree about usefulness I guess. Ultimately Ruby has worked just fine.
Due to tenacious teams. Not due to Ruby's technical virtues which are not that many. I admire people who can make anything work but I've also drank beer with some of them and they said that some days they think of committing suicide (I hope they were joking but they genuinely looked and sounded unhappy). I am talking PHP, Python, Ruby, Javascript.
> They didn't report massive issues, and the DB is going to be the bottle neck way before Ruby, so I just don't see an issue.
I remember the times in several apps I consulted for, long ago. We had good metrics systems in all of them and we had DB requests go from 5ms to 50ms and ActiveRecord itself (when subtracting the DB times) has routinely eaten 150ms to 250ms, sometimes more. I am aware that these issues have been fixed a while ago but it did leave a sour taste in my mouth and I can't just non-critially accept a claim that the DB dominates every latency in Rails world. Maybe it's true nowadays but during the dark times of Rails 2.x and 3.x it definitely was not.
Now Elixir... the last companies I contracted with we were talking 10-100 microseconds of Elixir code and 5+ ms of DB requests. Pretty neat.
...And then I consulted for two Golang projects where we had something like 100 to 400 nanoseconds of app code and 5+ ms of DB requests. Insane.
So I don't disagree with you on the concept but I do disagree somewhat that Ruby / Rails is not a resource hog. At one point it definitely was and it was humanly noticeable even.
But I can concede that nowadays this is very likely no longer true. I got no beef with any tech, I am simply a guy who is always looking for something better and thus I don't get attached to any tech. Elixir has served me very well in the last 7 years (together with Golang and Rust sprinkled in) but if e.g. Rust gains Erlang's / Elixir's transparent concurrency / parallelism abilities and fault tolerance and speed of development then I'd have zero qualms abandoning Elixir.
> So, wait, all apps are trivial in nature and can be built in less than a week?
Come on now, you are starting to sound like you want to misrepresent what I am saying. :) I was talking about quick MVPs / prototypes. Of course beyond those everything else is very different.
> So if you aren't building a trivial app but instead building something that takes 6 months in Ruby you'd be spending nearly 12 months in go.
You assume the curve of Elixir or Golang is linear; it's not. It's an asymptote.
To give you a contrived example:
- Month 1: Rails app at 20%, Elixir app at 10%
- Month 2: Rails app at 35%, Elixir app at 25%
- Month 3: Rails app at 45%, Elixir app at 40%
- Months 4 to 6: Rails app at 55%, Elixir app at 60%
- Months 7 to 9: Rails app at 80%, Elixir app at 90% and starting to work on final touches.
And so it went the few times I had the privilege of witnessing parallel Rails and Elixir development (including rewriting a few Rails apps to Elixir's Phoenix). The Rails guys knew their stuff pretty well and I liked working with them -- but even they admitted that they are regularly blocked on too many checks in tests or in the controllers themselves due to much weaker typing. (Though there were other reasons as well but hey, this comment became an essay already.)

I understand that you are skeptical. A lot of us cope with the fear of missing out by simply denying there's something to miss out on. Plus we can't be everywhere all at once so we eventually find our own corner and become experts there. All of that is completely fine and I am not judging; we can't all chase some theoretical perfection, plus when we hit 32-35 y/o the reality of "this is still just a job even if I like programming" sets in and we are all very excused for not researching and knowing every single alternative of doing things.
If I am reading you correctly, you disagree that the older tech (Ruby included) has outgrown its usefulness. Ultimately I don't think we disagree with each other because we are both right at the same time: maybe where you work and the people you communicate with Ruby / Rails are still deemed super good at what they do, they get the job done, the product brings enough revenue to drown out the drag that Rails can be and everyone is happy. Cool, more power to you. I however changed sub-careers in programming several times in a row and I am solving for tangibly different problems than what most Rails companies I've met back in the day did. And I've had a lot of financial success with Elixir, Golang and Rust, and my customers were super appreciative of the work done. Even now I am tutoring people who have 30+ years of programming experience and they are very happy with Elixir in particular.
We being in different bubbles is 100% fine. The world is big and rich and interesting. I am not disparaging your choice. Hopefully I am offering you an alternative take from another vantage point instead.
I took an effort to explain my views thoroughly, and you resorted to calling me disingenuous and irrational.
The part you quoted was the only piece that could be interpreted as seeking conflict -- though it had a more charitable interpretation that you decided to ignore -- and you latched onto that.
Oh well, I tried. Let the future readers judge for themselves.
Is there any large company at all that hasn't invested in making their tool chain better?
You talk about it like they are a failure. Lol
