Can when the specific situations are reached in very micro benchmark situations. But overall on aggregate you find even JIT languages don’t strictly outperform pre compiled languages for general workflows when looking at languages of a similar class. When you compare them to compiled languages like C/C++/rust/zip (aka ones without a GC or much of a runtime at all) then JIT languages fall behind like all other GCed languages.

Of these 25 reasons, most apply to a lot of languages and are far from Java exclusive or even java strong points. Pick any mainstream language and you will hit most of the benefits it lists here. With quite a few being almost meaningless. Like this:

Java/JVM/JIT can achieve runtime optimization on frequently run code, especially on something that’s running as a service so that you avoid the overheads from JVM startup times.

Compiled languages generally don’t need a JIT or to be optimized at runtime as they are compiled and optimized at compile time. And most language that don’t have a runtime like Javas already run faster than Java without its heavy startup time. Language with JITs are generally interpreted languages which have these same benefits as java lists here. Though do often suffer from other performance issues. But really at the end of the day all that really matters is how fast the language is and how good its startup times are. Java is not ahead of the pack in either of these regards and does not do significantly better then other languages in its same class (and often still drastically sucks for startup time).

Much of a company’s framework can be stable Java, with Scala or Clojure-backed business logic.

Many languages you can embed other languages inside. Nothing really special about scala or clojure here except that they work well with java. And I don’t really see this as a major benefit as most places I see dont separate their core code and business logic into different languages.

And the remaining issues that are more java specific are:

Java was one of the first mainstream GC strongly typed OOP languages. So it got its niche.

Java has been one of the main programming languages taught in colleges and universities in the last few decades.

Java’s Legacy Migration: Many banks in particular migrated legacy systems to Java in the early 2000’s when it was getting a lot of popularity and the industry was collectively in the midst of a huge OOP fever dream.

Which all paint a picture - it was popular long ago and taught in universities and lots of business pushed it when back in the day. And now it is hard to move off it.

And lastly:

What? How is this a point? If anything this should be a massive negative.

Not exactly 25 reasons to pick java in financial enterprise.

When I change devices or hit file size limits, I’ll compress and send things to my NAS.

Whaaatt!?!!? That sounds like you don’t use git? You should use git. It is a requirement for basically any job and there is no reason to not use it on every project. Then you can keep your projects on a server somewhere, on your NAS if you want else something like github/gitlab/bitbucket etc. That way it does not really matter about your local projects, only what is on the remote and with decent backups of that you don’t need to constantly archive things from your local machine.

Did you read the article at all?

“Putting all new code aside, fortunately, neither this document nor the U.S. government is calling for an immediate migration from C/C++ to Rust — as but one example,” he said. “CISA’s Secure by Design document recognizes that software maintainers simply cannot migrate their code bases en masse like that.”

Companies have until January 1, 2026, to create memory safety roadmaps.

All they are asking for by that date is a roadmap for dealing with memory safety issues, not rewrite everything.

Sounds like you just need to keep the data on your server and use samba or NFS and a network mount on the other devices.

What? You can easily escape from it if there are better alternatives you can use. Pointing at one language and saying it is not easy to code like it is another language is a pointless argument. You can do that about any two languages. They all differ for good reasons and as long as you can solve similar problems in both, even if in different ways then what does it matter that you cannot do it in the same way?

You could do a lot of things. Rust had a gc and it was removed so they have already explored this area and are very unlikely to do so again unless there is a big need for it that libraries cannot solve. Which I have not seen anyone that actually uses the language a lot see the need for.

Not like how async was talked about - that required a lot if discussion and tests in libraries before it was added to the language. GC does not have anywhere near as many people pushing for it, the only noise I see is people on the outside thinking it would be nice with no details on how it might work in the language.

So someone that is not involved in rust at all and does not seem to like the language thinks it will get a GC at some point? That is not a very credible source for such a statement. Rust is very unlikely to see an official GC anytime soon if ever. There are zero signs it will ever get one. There was a lot of serious talk about it before 1.0 days - but never made it into the language. Similar to green threads which was a feature of the language pre 1.0 days but dropped before the 1.0 release. Rust really wants to have a no required runtime and leans heavy on the zero-cost abstractions for things. Which a GC would impose on the language.

There are quite a few places where a GC is just not acceptable. Anything that requires precise timing for one. This includes kernel development, a lot of embedded systems, gaming, high frequency trading and even latency critical web servers. Though you are right that a lot of places a GC is fine to have. But IMO rust adds more than just fast and safe code without a GC - lots of people come to the language for those but stay for the rest of the features it has to offer.

IMO a big one is the enum support it has and how they can hold values. This opens up a lot of patterns that are just nice to use and one of the biggest things I miss when using other languages. Built with that are Options and Results which are amazing for representing missing values and errors (which is nicer than coding with exceptions IMO). And generally they whole type system leads you towards thinking about the state things can be in and accounting for those states which tends to make it easier to write software with fewer issues in production.

but imagine if you have to perform this operation for an unknown amount of runtime values

This is a poor argument. You dont write code like this in rust. If you can find a situation where it is an actual issue we can discuss things but to just say imagine this is a problem when it very likely is not a problem that can be solved in a better way at all let alone a common one is a very poor argument.

Typically when you want an escape from lifetimes that means you want shared ownership of data which you can do with an Arc. Cow and LazyLock can also help in situations - but to dismiss all these for some imagined problem is a waste of time. Comes up with a concrete example where it would help. Very likely you would find another way to solve the problem in any realistic situation you can come up with that I would suspect leads to a better overall design for a rust program.

I would say this is just a straw man argument - but you have not even created a straw man to begin with, just assume that one exists.

It doesn’t technically have drivers at all or go missing. All supporting kernel modules for hardware are always present at the configuration level.

This isn’t true? The Linux kernel has a lot of drivers in the kernel source tree. But not all of them. Notably NVIDIA drivers have not been included before. And even for the included drivers they may or may not be compiled into the kernel. They can and generally are compiled with the kernel but as separate libraries that are loaded at runtime. These days few drivers are compiled in and most are dynamically loaded depending on what hardware is present on the system. Distros can opt to split these drives up into different packages that you may or may not have installed - which is common for less common hardware.

Though with the way most distros ship drivers they don’t tend to spontaneously stop working. Well, with the exception of Arch Linux which deletes the old kernel and modules during an upgrade which means the current running kernel cannot find its drivers and stops dynamically loading them - which often results in hotplug devices like USB to stop working if you try to plug them in again after the drivers get unloaded (and need a reboot to fix as that boots into the latest kernel that has its drivers present).

Or refactored at a later date.

I don’t get it? They seem to be arguing in favor of bootc over systemd because bootc supports both split /usr and /usr merge? But systemd is the same. There is really nothing in systemd that requires it one way or another even in the linked post about systemd it says:

Note that this page discusses a topic that is actually independent of systemd. systemd supports both systems with split and with merged /usr, and the /usr merge also makes sense for systemd-less systems.

I don’t really get his points for it either. Basically boils down to they don’t like mutable root filesystem becuase the symlinks are so load bearing… but most distros before use merge had writable /bin anyway and nothing is stopping you from mounting the root fs as read-only in a usr merge distro.

And their main argument /opt and similar don’t follow /usr merge as well as things like docker. But /opt is just a dumping ground for things that don’t fir the file hierarchy and docker containers you can do what you want - like any package really nothing needs to follow the unix filesystem hierarchy. I don’t get what any of that has to do with bootc nor /usr merge at all.

You might want to checkout rust-script which essentially does the same but also lets you use it as a hashbang line to make executable rust scripts. And works with cargo/can install deps.

There is also an RFC for this feature.

TLDR; yes it does affect security. But quite likely not by any meaningful amount to be worth worrying about.

Any extra package you install is extra code on your system that has a chance to include vulnerabilities and thus could be an extra attack vector on your system. But the chances that they will affect you are minuscule at best. Unless you have some from of higher threat model then I would not worry about it. There are far more things you would want to tackle first to increase your security that have far larger effects than a second desktop environment being installed.

Creating functions is IMO not the first thing you should do. Giving variables better names or naming temporaries/intermediate steps is often all you really need to do to make things clearer. Creating smaller functions tends to be my last resort and I would avoid it when I can as splitting the code up can make things harder to understand as you have to jump around more often.

Comments are not always a waste of time, but comments that repeat or tell you what the code is doing (rather than why) are a waste. For legacy code you generally don’t have comments anyway and the code is hard to read/understand.

But if you can understand the code enough to write a comment you can likely refactor the code to just make it more readable to start with.

For code that does not change generally does not need to be read much so does not need comments to describe what it is doing. And again, if you understand it enough to write a comment to explain what it is doing you can refactor it to be readable to begin with. Even for mathematical equations I would either expect the reader to be able to read them or link to documentation that describes what it is in much more detail to name the function enough that the reader can look it up to understand the principals behind it.

And they were arguing the same - just renaming the property rather than reusing it. You should only have one not both but naming them differently can make it clear which one you have.

But here I am arguing to not have either on the user object at all. They are only needed at the start of a request and should never be needed after that point. So no point in attaching them to a user object - just verify the username and password and pass around user object after that without either the password or hash. Not everything needs to be added to a object.

Worse, refactors make comments wrong. And there is nothing more annoying then having the comment conflict with the code. Which is right? Is it a bug or did someone just forget to update the comments… The latter is far more common.

Comments that just repeat the code mean you now have two places to update and keep in sync - a pointless waste of time and confusion.

When is the hashed password needed other than user creation, login or password resets? Once you have verified the user you should not need it at all. If anything storing it on the user at all is likely a bad idea. Really you have two states here - the unauthed user which has their login details, and an authed user which has required info about the user but not their password, hashed or not.

Personally I would construct the user object from the request after doing auth - that way you know that any user object is already authed and it never needs to store the password or hash at all.
