“Give it six months”
It only needed 3!
Particularly unexpected, because 3! = 6.
That’s because C++ is such a high performance language, it gets things done faster
7m - 4m = 3m
My bad. I was going off OP first comment at 8 months and not the reply at 7 months.
I came back to be like actually no, but then I was like oh I’m the dumb dumb.
After you’ve done some languages, they all look the same. Yes, some have interesting features like the indent-based blocking of Python, and I’ll have to look up if the new language has “else if”, “elsif”, “elif”, or whatever, but als long as it is coming from the family of ALGOL-like languages, it does not matter much. You’ll learn the basic functions needed to get around, and off you go.
Just a few weeks ago, I started learning Python. Yes, this indenting takes some time to get used to. My son does Python for about a year now - he started with it at university. Maybe ten days after I started learning, I invited him to have a look at my first Python program. I have no idea what he expected. A “Hello, World” with a few extra features, maybe? Definitely not the 2.5k lines app I had written in my spare time, with GUI, databases, harvesting data from a web site with caching, and creating PDF files with optimized layout for the data I processed. In the end, it was just another programming language.
I guess you’ve never seen some of the 10-page template errors C++ compilers will generate. I don’t think anything prepares you for that.
I’ve seen way worse. Imagine a project that uses C preprocessor structures to make a C-compiler provide a kind-of C++. Macros that are pages long, and if you forget a single bracket anywhere, your ten pages look like a romance novel.
Or VHDL synthesis messages. You’ve got no real control over them, 99.9% of the warnings are completely irrelevant, but one line in a 50k lines output could hint at a problem - if you only found it.
So far, the output of C or C++ compilers (except for the above-mentioned project) has not been a problem or me, but I’m doing this for about 40 years now, so I’ve got a bit of experience.
Yep, sadly I’ve been exposed to a few such codebases before. I certainly learned a lot about how NOT to design a project.
You’ve been at it longer than I have, but I’ve already had coworkers look at me like I’m a wizard for decoding their error message. You do get a feel for where the important parts of the error actually are over time. So much scrolling though…

Yes, after decades of scanning large pages of text - code, errors, logs, search results, etc - a programmers ability to apply pattern recognition to screens of letters can be truly remarkable.
All I see now is blonde, brunette, redhead.

Yes, I have my share of coworkers asking me when they run into problems, too. They even ask me when they have Windows problems. And I don’t do Windows - I do Linux and embedded systems.
I had to do a module programming in VHDL for my EE degree.
Every time I see it mentioned anywhere I have a compulsion to scream: FUCK VHDL AND ITS FUCKING ERRORS! NO YOUR ANALYSIS & SYNTHESIS IS UNSUCCESSFUL!
I did not pursue a career in electronics…
One of the key problems of learning VHDL at universities is that most teachers there are amazingly clueless about the language. Not only do you need a bit of a different mindset (you do not program, you define), but their knowledge of language and systems is stuck in the last century.
When I was a regular in a VHDL group on the site we don’t mention here, we regularly had students who got taught techniques that are obsolete or at least deprecated since 1989.
I’ve not had those while working with concurrent programs with c++ for over a year. Pointers, QT programming, non-qt backend programming, coding an engine to work with computer vision runners (openvino mostly), image management (more pointers)… Idk, this is gonna sound rude but just code better? Most of my errors were segfaults, I have had to plug the debugger and/or tons of prints and I made it work.
If you want to see giant error logs, check pyspark errors. But even those have the relevant line of info and then all the rest of the garbage info that no one really needs, like any other language.
It really depends what you’re doing. The last big project I did with C++ templates was using them to make a lot of compile-time guarantees about concurrency locks so they don’t need to be checked at runtime (thus trading my development time for faster performance). I was able to hide the majority of the templates from users of the library, and spent extra time writing custom static_assert messages.
C++ templates are in fact a compile-time turing complete language, as crazy as that sounds.
Yeah this only really applies to Algol style imperative languages. Dependent types and say stack languages like idris and apl are dramatically different in their underlying axioms.
Indeed. I have done languages like Prolog and Forth, too, and have actually written a bit in APL ages ago. Yes, they are different, but in the end, it just adds a little bit of complexity. The underlying algorithms are universal, just the methods and structures to achieve them differ. Actually, the first programming language I have written was a simplified Forth derivate - in 6510 Assembler.
I didn’t even know about the Python indentation thing until I was practically done learning it! I’m just used to copying whatever indentation scheme my coworkers are using, for consistency.
I’m interested in specifically what your first program did?
Like what data is it harvesting and how is it showing that in PDFs or should I say why?
The software gets data from a website named bricklink.com, where one can buy and sell LEGO bricks and sets.
The main view holds a list of bricks I’ve selected from the large range available. In a requester to add parts, I can select a certain brick from the list of existing bricks by first chosing a category (e.g. “Bricks”) in the leftmost column, then chosing it’s shape (e.g. “Brick 2x4”) in the middle one, and then selecting the color (of the known existing colors for this brick, e.g. “Black”) in the right column. On all three selections I can multi-select and sort, which allows me to select e.g. a number of different Bricks, then sort the last view by color, and multiselect those bricks in the color I need. OK’ing the requester add the part(s) to my list.
The list that shows all the properties (including when this part was in production, how much a single brick of it weighs, as well as mold codes and article numbers). From there, I can choose some bricks (usually 15 in a go) to print, which produces a PDF with 15 labels on a double-sided A4-paper with cut-marks on one side. I cut them along the cut marks and put them into the bag with the coresponding part. This is quite helpful, if you consider a box with bags all containing e.g. black parts and bad lighting conditions in the storage room. Alternatively, I can print a double-sided paper with four larger cards to cut, which I laminate and use for marking boxes when I have larger amounts of one brick shape and color.
I can (and do) export those bricks to an export folder as CSV once I’ve printed the labels. In a future version of the software, I will be able to take a bag or box of parts from my collection, select it in my software via it’s article number, and derive an approximate count by weighing them (therefor the parts weight) to get an approximate inventory.
Hey, thanks for explaining the project for me. That sounds fascinating, is it public? Not that I want to steal it, I never got into Lego, just would like to see exactly how it works.
It also begs the question of how much Lego you actually have lol.
I’ve been thinking of building Lego when I’m sad but it seems so expensive.
No, the project is still in its early stages, far from what I would publish.
Regarding the amount of LEGO, well, if I write a resource management and inventory system, you can imagine that it is a bit more than a handfull. My current estimates are around one million bricks, give or take a few hundred k. One of the reason to inventorize it…
Thanks again.
Do you make money with Lego or is it purely a hobby. Apologies for the questions I’m inherently curious and this is very interesting.
I don’t make money with it, on the contrary - my son is a bit more direct here and claims I’m wasting money ;-) It is just a hobby. OK, a big one. I build my own models for fun and exhibit them at shows and events.
And: Curiosity is good. It kept the human race advancing.
Thanks again.
I would say that it isn’t wasted money if it’s something you enjoy and brings you pleasure or satisfaction.
Definitely not the 2.5k lines app
MVC can be a great experience, especially with python dictionaries.
Learning how to get models and views together took some time, but after the second refactoring that week I managed to have neat objects for each MVC with clean interfaces. My biggest source in the app defines a requester with three columns of lists: a global category, then parts from that category, and finally the available colors for that part. Each of those views is an object, their interacting logic is an object, and finally the actual requester is an object, and this makes thing easy to handle.
Great!
Disclaimer: I actually like C++ the language, I’m reasonably comfortable with it and enjoy it as an upgrade from C. I don’t use much OOP stuff as I’m writing a game using the flecs ECS. So things like abstract classes are mostly absent from my codebase.
What has been driving me up the wall the last month has been build systems and dependencies: don’t get me wrong; meson is great but the problem is not everyone uses meson. All I want to do is add some library built with cmake as a dependency without needing to rewrite the build system or install it on my OS. Apparently that is too much to ask!
I’m seriously considering dropping everything and jumping to Rust because of Cargo. Yes I’ve tried setting up conan but not having much fun since the packages are all third party and out of date anyways
I’m seriously considering dropping everything and jumping to Rust because of Cargo.
Well if you’re into game dev, ECS and Rust, there’s like a 99% chance you know of it, but just in case you don’t: We have bevy, now with an extra full-time dev (Alice, who’d been working hard at it for years, I think she’s a bigger contributor than the author himself at this point lol)
I’ve been keeping an eye on bevy, it looks really cool. I’ll probably make something with it one day when their ECS gets support for entity relationships (which appears to be in the pipeline). A really cool project though, basically looks like everything I’ve wanted out of a C++ engine which I can’t really use due to build system mixing.
Rust’s cargo is great, I’d say it would be best to make the switch sooner rather than later once your code base is established. The build system and tooling alone is a great reason to switch
What sucks is I’ve been working on this hobby project for nearly 4 years now. It started in C#, moved to C, now C++. It’s at the stage where a lot of basic functionality has been implemented, with the largest component, the Vulkan based renderer being maybe 1/4 implemented. The core game stuff is ECS based and flecs has a rust binding so migrating that will be easy. Renderer will just become even further from completion. I’m worried that there will be new problems that are maybe more inhibiting, but this is meant to be a fun project and build systems aren’t fun. It’s a difficult balance and I’m not the only person involved, the other person isn’t as convinced by cargo as they haven’t spent days working on the build system
I’m a gameplay programmer who have worked with Unity and Unreal and I’ve experiment with Rust for gamedev(though only for hobby projects) and for regular code. My conclusions so far is that Rust sucks for gameplay code, for most other things it’s kinda nice.
The biggest reason is that it’s much harder to write prototype code to test out an idea to see if it’s feasible and feels/looks good enough. I don’t want to be forced to fully plan out my code and deal with borrowing issues before I even have an idea of if this is a good path or not.
I would say though that because you are using ECS stuff it is at least plausible to do in Rust but at least for my coding/development style it still isn’t a good fit.

There are options for this with Rust. If you wanted to use pure Rust you could always use unsafe to do prototyping and then come back and refactor if you like it. Alternatively you could write bindings for C/C++ and do prototyping that way.
Though, I will say that this process gets easier as you gain more experience with Rust memory management.
Not really. Unsafe doesn’t allow you to sidestep the borrow checker in a decent way. And even if you do it the Rust compiler assumes non aliasing and breaking that will give you loads of unexpected problems that you wouldn’t get in a language that assumes aliasing…
Testing something that only has side effects to the local scope is probably not too hard but that isn’t the most common case for gameplay code in my experience…
Going through another language basically has the same issues as unsafe except it’s worse in most ways as you’d need to keep up to date bindings all the time plus just the general hassle of doing it for something that could have been a 10 min prototype with most other setups…
Now sure it’s possible that I would have better result after doing even more rust, especially with some feedback from someone who really knows it but that doesn’t really change anything in just general advice to people who is already working on something in C++ as they likely won’t have that kind of support either.
Story by a game dev who gave up on Rust after 3 years https://loglog.games/blog/leaving-rust-gamedev/
Brackeys started a series on Godot recently. If you are writing a smaller game GDscript looks attractive and far simpler.
Being a Python simp, I find GDscript just different enough to nag. There’s a lot of QoL stuff they don’t have and aren’t (currently) looking to add in order to keep the language simple. Honestly has me looking to use C# instead.
They’re mucking it about a little though, like that post when checking if types don’t match ‘! value is type’ can now be ‘value is not type’ which is more readable but not as logical in terms of the language.

So things like abstract classes are mostly absent from my codebase.
I believe the consensus nowadays is that abstract classes should be avoided like the plague even in languages like Java and C#.
I have not heard this consensus. Definitely inheritance where the base class holds data or multiple inheritance, but I thought abstract was still ok. Why is it bad?
In 99% of the cases, inheritance can easily be replaced with composition and/or interfaces. Abstract classes tend to cause hard dependencies that are tough to work with.
I’m not sure why you would use abstract classes without data. Just use interfaces.
How do you implement an interface in C++ without an abstract class?
Ask Bjarne to add interfaces enough many times until he gives in.
On a more serious note, I’m not exactly sure what the best C++ practice is. I guess you just have to live with abstract classes if you really want interfaces.
An abstract class with no member variables serves the same purpose in C++.
Say List is an interface.
You have implementations like ArrayList and LinkedList.
Many of those method implementations will differ. But some will be identical. The identical ones go in the abstract base class, so you can share method implementation inheritance without duplicating code.
That’s why.
Last time I did anything on the job with C++ was about 8 years ago. Here’s what I learned. It may still be relevant.
- C++14 was alright, but still wasn’t everything you need. The language has improved a lot since, so take this with a grain of salt. We had to use Boost to really make the most of things and avoid stupid memory management problems through use of smart (ref-counted) pointers. The overhead was worth it.
- C++ relies heavily on idioms for good code quality that can only be learned from a book and/or the community. “RAII” is a good example here. The language itself is simply too flexible and low-level to force that kind of behavior on you. To make matters worse, idiomatic practices wind up adding substantial weight to manual code review, since there’s no other way to enforce them or check for their absence.
- I wound up writing a post-processor to make sense of template errors since it had a habit of completely exploding any template use to the fullest possible expression expansion; it was like typedefs didn’t exist. My tool replaced common patterns with expressions that more closely resembled our sourcecode1. This helped a lot with understanding what was actually going wrong. At the same time, it was ridiculous that was even necessary.
- A team style guide is a hard must with C++. The language spec is so mindbogglingly huge that no two “C++ programmers” possess the same experience with the language. Yes, their skillsets will overlap, but the non-overlapping areas can be quite large and have profound ramifications on coding preferences. This is why my team got into serious disagreements with style and approach without one: there was no tie-breaker to end disagreement. We eventually adopted one after a lot of lost effort and hurt feelings.
- Coding C++ is less like having a conversation with the target CPU and more like a conversation with the compiler. Templates,
const,constexpr,inline,volatile, are all about steering the compiler to generate the code you want. As a consequence, you spend a lot more of your time troubleshooting code generation and compilation errors than with other languages. - At some point you will need
valgrindor at least a really good IDE that’s dialed in for your process and target platform. Letting the rest of the team get away without these tools will negatively impact the team’s ability to fix serious problems. - C++ assumes that CPU performance and memory management are your biggest problems. You absolutely have to be aware of stack allocation, heap allocation, copies, copy-free, references, pointers, and v-tables, which are needed to navigate the nuances of code generation and how it impacts run-time and memory.
- Multithreading in C++14 was made approachable through Boost and some primitives built on top of pthreads. Deadlocks and races were a programmer problem; the language has nothing to help you here. My recommendation: take a page from Go’s book. Use a really good threadsafe mutable queue, copy (no references/pointers) everything into it, and use it for moving mutable state between threads until performance benchmarks tell you to do otherwise.
- Test-driven design and DevOps best-practice is needed to make any C++ project of scale manageable. I cannot stress this enough. Use every automated quality gate you can to catch errors before live/integration testing, as using valgrind and other in-situ tools can be painful (if not impossible).
1 - I borrowed this idea from working on J2EE apps, of all places, where stack traces get so huge/deep that there are plugins designed to filter out method calls (sometimes, entire libraries) that are just noise. The idea of post-processing errors just kind of stuck after that - it’s just more data, after all.
C is dangerous like your uncle who drinks and smokes. Y’wanna make a weedwhacker-powered skateboard? Bitchin’! Nail that fucker on there good, she’ll be right. Get a bunch of C folks together and they’ll avoid all the stupid easy ways to kill somebody, in service to building something properly dangerous. They’ll raise the stakes from “accident” to “disaster.” Whether or not it works, it’s gonna blow people away.
C++ is dangerous like a quiet librarian who knows exactly which forbidden tomes you’re looking for. He and his… associates… will gladly share all the dark magic you know how to ask about. They’ll assure you, oh no no no, the power cosmic would never turn someone inside-out, without sufficient warning. They don’t question why a loving god would allow the powers you crave. They will show you which runes to carve, and then, they will hand you the knife.
I actually just started learning C++ today.
If Lovecraft were alive today one of his stories would start with this line.
Jokes aside, I struggle more with abominations like JavaScript and even Python.
Do you have a minute for our lord and savoir TypeScript?
As long as it can distinguish between int and uint - yesss!
TypeScript is still built on JavaScript, all numbers are IEEE-754 doubles 🙃
Edit: Actually I lied, there are BigInts which are arbitrarily precise integers but I don’t think there’s a way to make them unsigned. There also might be a byte-array object that stores uint8 values but I’m not completely sure if I’m remembering that correctly.
Not only is there a UInt8Array, there’s also a bunch of others: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray#typedarray_objects
Yeah JavaScript is a bit weird, semicolons being optional and compulsory at the same time: I remember trying to build an electron example ~5yrs ago and it didn’t work unless I put in the semicolons which the developers omitted.
Python is just glorified shell scripting. Libraries like numpy are cool but I don’t like the indentation crap, I’m getting used to it because University likes it.
but I don’t like the indentation crap
Do you not use indentation in other languages?
Python is just glorified shell scripting
Absolutely not, python is an actual programming language with sane error handling and arbitrarily nestable data structures.
I don’t like the indentation crap
Don’t be so superficial. When learning something, go with the flow and try to work with the design choices, not against them.
Python simply writes a bit differently: you do e.g. more function definitions and list comprehensions.
Python has its quirks, but it’s much much cleaner than js or c++, not fair to drag it down with them imo
I think the thing with C++ is they have tried to maintain backward compatibility from Day 1. You can take a C++ program from the 80s (or heck, even a straight up C program), and there’s a good chance it will compile as-is, which is rather astonishing considering modern C++ feels like a different language.
But I think this is what leads to a lot of the complexity as it stands? By contrast, I started Python in the Python 2 era, and when they switched to 3, I was like “Wow, did they just break hello world?” It’s a different philosophy and has its trade-offs. By reinventing itself, it can get rid of the legacy cruft that never worked well or required hacky workarounds, but old code will not simply run under the new interpreter. You have to hope your migration tools are up to the task.
even a straight up C program
There were breaking changes between C and C++ (and some divergent evolution since the initial split) as well as breaking changes between different releases of C++ itself. I am not saying these never happened, but the powers that be controlling the standard have worked hard to minimize these for better or worse.
If I took one of my earliest ANSI C programs from the 80s and ran it through a C++23 compiler, I would probably need to remove a bunch of
registerstatements and maybe check if an assumption of 16-bitintis going to land me in some trouble, but otherwise, I think it would build as long as it’s not linking in any 3rd party libraries.
Reminds me of the joke about the guy falling from the top of the Empire State Building who, half way down, was heard saying: “Well, so far, so good”
Reminds me of the start of La Haine.
https://youtu.be/4rD05HsmtIUI suspect indirectly both variants come from the same source or maybe even it’s the La Haine that’s indirectly the source for my variant (though I learned this joke a long time ago, possibly before 1995).
By the way, that’s excellent film intro.
This is so believable. You copy a few examples out of a textbook using cout and cin and it seems reasonably inline with other languages.
A friend of mine whose research group works on high throughout X-ray Crystallography had to learn C++ for his work, and he says that it was like “wrangling an unhappy horse”.
I’m not sure how I feel about someone controlling an X-ray machine with C++ when they haven’t used the language before… At least it’s not for use on humans.
Yep, I learned about this exact case when I got my engineering degree.
He doesn’t directly control anything with C++ — it’s just the data processing. The gist of X-ray Crystallography is that we can shoot some X-rays at a crystallised protein, that will scatter the X-rays due to diffraction, then we can take the diffraction pattern formed and do some mathemagic to figure out the electron density of the crystallised protein and from there, work out the protein’s structure
C++ helps with the mathemagic part of that, especially because by “high throughput”, I mean that the research facility has a particle accelerator that’s over 1km long, which cost multiple billions because it can shoot super bright X-rays at a rate of up to 27,000 per second. It’s the kind of place that’s used by many research groups, and you have to apply for “beam time”. The sample is piped in front of the beam and the result is thousands of diffraction patterns that need to be matched to particular crystals. That’s where the challenge comes in.
I am probably explaining this badly because it’s pretty cutting edge stuff that’s adjacent to what I know, but I know some of the software used is called CrystFEL. My understanding is that learning C++ was necessary for extending or modifying existing software tools, and for troubleshooting anomalous results.
Neat, thanks for sharing. Reminds me of old mainframe computers where students and researchers had to apply for processing time. Large data analysis definitely makes sense for C++, and it’s pretty low risk. Presumably you’d be able to go back and reprocess stuff if something went wrong? Or is more of a live-feed that’s not practical to store?
The data are stored, so it’s not a live-feed problem. It is an inordinate amount of data that’s stored though. I don’t actually understand this well enough to explain it well, so I’m going to quote from a book [1]. Apologies for wall of text.
“Serial femtosecond crystallography [(SFX)] experiments produce mountains of data that require [Free Electron Laser (FEL)] facilities to provide many petabytes of storage space and large compute clusters for timely processing of user data. The route to reach the summit of the data mountain requires peak finding, indexing, integration, refinement, and phasing.” […]
"The main reason for [steep increase in data volumes] is simple statistics. Systematic rotation of a single crystal allows all the Bragg peaks, required for structure determination, to be swept through and recorded. Serial collection is a rather inefficient way of measuring all these Bragg peak intensities because each snapshot is from a randomly oriented crystal, and there are no systematic relationships between successive crystal orientations. […]
Consider a game of picking a card from a deck of all 52 cards until all the cards in the deck have been seen. The rotation method could be considered as analogous to picking a card from the top of the deck, looking at it and then throwing it away before picking the next, i.e., sampling without replacement. In this analogy, the faces of the cards represent crystal orientations or Bragg reflections. Only 52 turns are required to see all the cards in this case. Serial collection is akin to randomly picking a card and then putting the card back in the deck before choosing the next card, i.e., sampling with replacement (Fig. 7.1 bottom). How many cards are needed to be drawn before all 52 have been seen? Intuitively, we can see that there is no guarantee that all cards will ever be observed. However, statistically speaking, the expected number of turns to complete the task, c, is given by:
where n is the total number of cards. For large n, c converges to n*log(n). That is, for n = 52, it can reasonably be expected that all 52 cards will be observed only after about 236 turns! The problem is further exacerbated because a fraction of the images obtained in an SFX experiment will be blank because the X-ray pulse did not hit a crystal. This fraction varies depending on the sample preparation and delivery methods (see Chaps. 3–5), but is often higher than 60%. The random orientation of crystals and the random picking of this orientation on every measurement represent the primary reasons why SFX data volumes are inherently larger than rotation series data.The second reason why SFX data volumes are so high is the high variability of many experimental parameters. [There is some randomness in the X-ray pulses themselves]. There may also be a wide variability in the crystals: their size, shape, crystalline order, and even their crystal structure. In effect, each frame in an SFX experiment is from a completely separate experiment to the others."
“The Realities of Experimental Data” "The aim of hit finding in SFX is to determine whether the snapshot contains Bragg spots or not. All the later processing stages are based on Bragg spots, and so frames which do not contain any of them are useless, at least as far as crystallographic data processing is concerned. Conceptually, hit finding seems trivial. However, in practice it can be challenging.
“In an ideal case shown in Fig. 7.5a, the peaks are intense and there is no background noise. In this case, even a simple thresholding algorithm can locate the peaks. Unfortunately, real life is not so simple”
It’s very cool, I wish I knew more about this. A figure I found for approximate data rate is 5GB/s per instrument. I think that’s for the European XFELS.

That’s definitely a non-trivial amount of data. Storage fast enough to read/write that isn’t cheap either, so it makes perfect sense you’d want to process it and narrow it down to a smaller subset of data ASAP. The physics of it is way over my head, but I at least understand the challenge of dealing with that much data.
Thanks for the read!
Probably makes 7 figures working for big pharma though
Unfortunately no. I don’t know any research scientists who even make 6 figures. You’re lucky to break even 50k if you’re in academia. Working in industry gets you better pay, but not by too much. This is true even in big pharma, at least on the biochemical/biomedical research front. Perhaps non-research roles are where the big bucks are.
The image doesn’t open for me. But I guess the joke still works in a way.
Does it show in the post body?
Instructions unclear, attempted to learn JS
I learned c from a book from the 80s and then skipped to rust.
The only time I touched c++ was modding games in the early aughts and to try it for a couple coding challenges. I’ve heard templates are a thing of note when it comes to complications but not sure.
As for c# … We don’t talk about that (jk. I had to do it for one or two projects and played with unity a bit ages ago)
Was that “The C Programming Language”? I learned C from that after a bit of C++ and it made everything make so much sense. C is refreshingly simple.
I’ve heard templates are a thing of note when it comes to complications but not sure
It’s funny because that is the one feature I really wish C had, I can live without member functions but templates or even a good generics system would be great. I did some C# with MonoGame and FNA. Language has gotten better as of late but idk about performance, way better than VB.
Probably. I think I still have the book in storage back in the US. At some point, I also got “learn c in 24 hours” or something as well.
Honestly C# has grown on me quite a bit. Shakes off some of the bloat of Java and linq is pretty handy. God knows if I can’t tell you what the distinction is between C# and .NET Core and whatever the hell ASP is.
- C# = Java (the language itself)
- .NET (Core) = Oracle JDK (a runtime and std lib implementation for the language)
- ASP.NET = Spring boot (the default web framework)
Thank you!!
We used C++ based software. Who need sanity ? Clearly overrated
Sums up my experience with C++. It’s fun until you actually start using it and then you get hit with: Idiotic syntax, no package management, C compilers, different operating systems, compiling in general, having to code everything from scratch, memory management and a lot more…
Shit hit me so hard, I began learning web dev instead and never looked back…
Yeah. Here I am 26 days later effectively repeating the meme because I’ve started writing a project on Rust
