Recently this link was on HN[1]. It ranks your browser on regular tracking and fingerprinting separately. "Tor without JS" was the only option I found to be completely fingerprint resistant. Even Tor "with JS on strict settings" ranked it as only "partly fingerprint resistant". (Interestingly firefox without JS never returns)
Scary stuff.
I'd like to hear other people's experiences/experiments here.
The flip side of this, having the complementary flaw of testing only persistence, not uniqueness, is (warning, real tracking link) fingerprinting.com/demo. You can try resetting your ID and seeing if it changes here. Since tracking requires (a degree of) uniqueness AND (a degree of) persistence, the danger signal is only failing both the EFF test and this test.
Failing both is a requirement to derive meaning, not being lax: measuring only uniqueness would fail a random number generator, and measuring only persistence would fail the number 4.
Your link doesn't work though. I just get "file not found".
>Your browser fingerprint has been randomized among the 378,837 tested in the past 45 days. Although sophisticated adversaries may still be able to track you to some extent, randomization provides a very strong protection against tracking companies trying to fingerprint your browser.
>Currently, we estimate that your browser has a fingerprint that conveys at least 18.53 bits of identifying information.
Anyway, this test doesn't really communicate the results very well. Yes, Tor browser stands out. No, it's not easy to differentiate between different Tor browser users via this kind of fingerprinting.
Did you change a setting or add an ad blocker or something?
edit: I feel like someone with a username "monerozcash" must have some customization to your browsing experience, that maybe you don't even remember doing...
I got a very similar result on unmodified iOS Safari, randomized among 380k users and conveying 15.5 bits of information. I only have the Dark Reader extension.
EDIT: just saw I need to download playonlinux or wine. Forget about it.
Let me rephrase it: you believe it, I don't believe.
For window size only 1 in 380326.0 browsers has this value.
I'm downloading safari right now.
EDIT: just saw I need to download playonlinux or wine. Forget about it.
Sorry, who concluded that this is fingerprintin resistant? Does the website tell you that, or was this your conclusion? Because my reading is with a number that small, you're almost uniquely identifiable. Is it possible you're misunderstanding what the report is showing?
Would you be assed to continue this conversation elsewhere? I'd like to get to the bottom of this?
Those two values are the only ones returned by the browser which are useful for fingerprinting beyond "stock safari". Window size being the biggest part of that, but window size tends to change fairly regularly.
"Our tests indicate that you have strong protection against Web tracking."
"Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 301.9 browsers have the same fingerprint as yours.
Currently, we estimate that your browser has a fingerprint that conveys 8.24 bits of identifying information."
Interestingly, increasing the Tor Browser Security level from Safe to Safer actually increased the bits of identifying information and reduced the anonymity:
"Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 832.32 browsers have the same fingerprint as yours.
Currently, we estimate that your browser has a fingerprint that conveys 9.7 bits of identifying information."
And at the Safest Security level (i.e. with JS diabled) the identifying bits and anonymization appear to be at their best:
"Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 261.41 browsers have the same fingerprint as yours.
Currently, we estimate that your browser has a fingerprint that conveys 8.03 bits of identifying information."
How?
It's possible that if Rust had remained "secret sauce" for Mozilla it would have hurt its usage elsewhere, impossible at this distance in time to be sure. There is, for example, far less Rust in Chromium (less than 4%) than in Firefox (more than 12%).
13 years to get to v0.0.1 is a success? Look at how much progress Ladybird has made in a fraction of that time. Remember that these people are constantly starting rewrites of C and C++ projects (when they're not demanding others do it) in Rust "for safety" (and "oops it's MIT now"), even of ancient Unix utilities with minimal attack surfaces like the "date" command, yet when it comes to a browser rendering engine, which entails computationally-intensive, aggressively-optimized rendering of untrusted input--a massive attack surface, and the very thing for which Rust was supposedly designed--they somehow can't get the right combination of enough Rust zealots (and Adderall) to get past the finish line.
Your life might improve if you stop believing that Rust devs belong to a cult of your own imagination.
Servo was meant to be a test-bed for new architectures that might or might not be usable by Firefox. It was never meant to become Firefox' new web renderer, and it wasn't until more recently and long after the Mozilla-pocalypse that a new team took over the project with a goal of productionalizing the project as a whole. Stylo, for example, was integrated into Firefox 57 and allowed for parallel CSS style calculation, an effort that was tried unsuccessfully multiple times in C++.
A TS compiler from scratch built in Rust would be fine.
> cultists
The cult is in your imagination.
> You can frame that as an architectural concern...
"Go also offers excellent control of memory layout and allocation (both on an object and field level) without requiring that the entire codebase continually concern itself with memory management."
"The TypeScript compiler's move to Go was influenced by specific technical requirements, such as the need for structural compatibility with the existing JavaScript-based codebase, ease of memory management, and the ability to handle complex graph processing efficiently. "
If memory management and ability to handle complex graph processing efficiently isn't related to architecture to you I don't know what to tell you.

> The cult is in your imagination.
CTRL+F "rust" on the Go issue and see how many results you get. 31 for me and that's before expanding spam.
Rust can do complex graph processing, as well as efficient easy memory management, but it's going to do it in a different structure than a GCed lang would. Hence my statement that 1 to 1 translation was the primary factor.
> CTRL+F "rust" on the Go issue and see how many results you get.
Yes and so what? There's 35 for .NET or 74 for C#, yet you don't see people claiming the C# cult was harassing the TS team.
That's exactly why we have different languages and tools, because they adapt differently to different projects, teams and problems.
But as soon as you get into the silly "tool X is better period" arguments, then all the nuance of choosing the right tool for the job is lost.
In addition, you could more easily inadvertently introduce security problems.
Is Rust the right choice for Tor? Sure. Is Tor the right choice for security? If they moved to Rust, they increased security risks to make it easier to manage and find help from younger less-experienced developers, so no.
I believe that depends on the sophistication of algorithms. High-level algorithms (especially if they involve concurrency or parallelism) are much easier to write in Rust (or in C++) than in C, which gives them a pretty good chance to be at least as fast as any reasonably safe C implementation.
For low-level algorithms, of course, it's really hard to beat polished C code.
> Out-of-the-box, I’m guessing people will use too many cargo packages, each that are over-engineered or written by less-experienced developers, so it will be less efficient and less performant.
I don't think that this is going to be a problem. The Tor Project developers I've interacted with sounded quite serious about security. Forbidding non-blessed cargo packages is pretty trivial.
> In addition, you could more easily inadvertently introduce security problems.
What do you mean?
Or, you could look at other projects who have been using Rust for many years, and consider these factors there too. The folks who have have generally concluded the opposite.
The parent poster's point is seemingly to reject "this is simply the better thing" (ie: "small code is better") and instead to focus on "for what we are doing it is the better thing". Why would "basic" profiler use be better than "niche" or "advanced" profiler use if for that context basic would actually have been inferior (for whatever value of basic we choose to go with)?
It seems to me that the reality we're often confronted with is that "better" is contextual, and I would say that "basic" or "smaller" are contextual too.
This sort of gamification of discourse is poison if you actually care about good faith or reasonable discussions. HN is not a good place for either.
1. Programmer skill and talent are not enough to achieve similar security properties with memory-unsafe languages as with memory-safe languages.
2. Therefore, "memory-safe languages are technically superior, period, for applications processing untrusted data where security is an important goal", is not an un-nuanced argument nor a Rust fanboy argument, but self-evident.
That still leaves a lot of room for other languages (Rust is not my favorite language), but it pushes back against the developer equivalent of doctors and pilots resisting the adoption of checklists for decades because "I wouldn't make those kinds of mistakes so stop messing with my work".
1. Programmer skill and talent are not enough to achieve similar security properties with memory-unsafe languages as with memory-safe languages.
2. Therefore, "memory-safe languages are technically superior, period, for applications processing untrusted data where security is an important goal"
but the problem entirely boils down to what comes next:
3a. Therefore everything should use rust.
3b. Therefore everything processing untrusted data where security is an important goal should use rust. (Some folks like to stretch what could possibly process untrusted data to turn this into 3a, but there is a difference.)
3c. Therefore most programs really should be written with a garbage-collector, or if they really need to be low-level or high performance they should use an appropriate stack to avoid gc while remaining safe (whether that's Rust, Ada+SPARK, formally-verified assembly, or whatever).
I think you make an important oversight with these claims, which is that you can enforce logical safety over a memory unsafe language and have a much higher degree of safety than memory safety. Formally verified C doesn't change the language, you can in principle take C code run through compcert and compile it elsewhere. It's still a memory unsafe language, but we can express a much higher degree of safety than simple memory safety.
Another aspect to consider is that all garbage collected languages are memory safe. A language like Python actually has a far greater degree of memory safety than a language like Rust because it offers no ability to break memory safety (without calling into foreign code), while Rust lets you do it within unsafe blocks using raw pointers. That being said, anybody who would suggest using Python over Rust in a security-focused context is completely out of their mind.
In serious places where security is critical and margin for error is low, formal verification has existed for decades and is the standard. Any operation - specifically in the context where security is critical - which is not formally verifying its software is a mickey mouse operation, because they're fundamentally compromising on security to an unacceptable degree. I think it would be nice to have a formal verification toolchain and language extension for Rust to allow for full logical safety, but last I checked this area was still a work in progress for the language.
I know anytime Rust is brought up, someone brings up logical safety, and patterns are annoying. Rust obviously has a lot of tricks up its sleeve to automatically detect issues that a language like C++ cannot. Naive Rust is preferable over naive usage of a memory unsafe language. The problem is that in a serious security critical context, "naive" is completely unacceptable. If security is a core goal, there can be no replacement for fully blown logical safety enforcing strict behavioral and structural guarantees in every single facet of the codebase. I know the line, that logical safety is excruciatingly labor intensive and so the tradeoff with using Rust is that it affords some of the safety of formally spec'd and proven code. The problem is that the amount it affords you is completely marginal. The safety gap between C and Rust is much smaller than the safety gap between Rust and formally proven correct SPARK. It's just the reality. I'm loathe to see a future where marketing hype sees a degeneration of tools because it was presented as a serious alternative.
You've probably heard that "It is difficult to get a man to understand something, when his salary depends on his not understanding it" and so of course we shouldn't expect such people to say "Don't write this in C++" when they can instead get paid to teach "How to write this in C++" for 2-3 days and feel like they made the world a better place on top.
It so happens Rust is my favourite language, or at least, my favourite general purpose language, but it's also true that I am currently mostly paid to write C# and I see absolutely no reason why I'd say "No, this should be Rust" for most work I do in C#

Is that comment outdated? The blog post gave me a different impression. If Arti is not ready yet, shouldn't that have been made clear in the blog post and in the various posts here? Not directing it at you, amelius.
The Rust specialty is memory safety and performance in an relatively unconstrained environment (usually a PC), with multithreading. Unsurprisingly, because that's how it started, that's what a web browser is.
But Tor is also this. Security is extremely important as Tor will be under attack by the most resourceful hackers (state actors, ...), and the typical platform for Tor is a linux multicore PC, not some tiny embedded system or some weird platform, and because it may involve a lot of data and it is latency-sensitive, performance matters.
I don't know enough of these projects but I think it could also take another approach and use Zig in the same way Tigerbeetle uses it. But Zig may lack maturity, and it would be a big change. I think it is relevant because Tigerbeetle is all about determinism: do the same thing twice and the memory image should be exactly the same. I think it has value when it comes to security but also fingerprinting resistance, plus, it could open the way for dedicated Tor machines, maybe running some RTOS for even more determinism.
The big thing is memory allocation, sometimes, on tiny systems, you can't malloc() at all, you also have to be careful about your stack, which is often no more than a few kB. Rust, like modern C++ tend to abstract away these things, which is perfectly fine on Linux and a good thing when you have a lot of dynamic structures, but one a tiny system, you usually want full control. Rust can do that, I think, like C++, it is just not what it does best. C works well because it does nothing unless you explicitly ask for it, and Zig took that philosophy and ran away with it, making memory allocation even more explicit.
What makes you say that?
So unless they provide some Tor specific nuance, it's more or less applicable to wide range of applications.
On the other hand, most developers have no need of writing `unsafe` Rust. The same tools used for static and dynamic analysis of C codebases are available to Rust (ASAN and friends) and it is a good idea to use them when writing `unsafe` (plus miri).
The reason I'm replying is that "the impact of Rust on memory safety" is always a conversation that gets outsized amounts of ink that it drains focus away from other things. I would argue that sum types and exhaustive pattern matching are way more important to minimize logic bugs, even if they aren't enough. You can still have a directory traversal bug letting a remote service write outside of the directory your local service meant to allow. You can still have TOCTOU bugs. You can still have DoS attacks if your codebase doesn't handle all cases carefully. Race conditions can still happen. Specific libraries might be able to protect from some of these, and library reuse increases the likelihood of of these being handled sanely (but doesn't ensure it). Rust doesn't protect against every potential logic error. It never claimed to, and arguing against it is arguing against a strawman. What safe-Rust does claim is no memory safety bugs, no data races, and to provide language and tooling features to model your business logic and deal with complexity.
Admittedly I stopped after going through a bunch of useless stuff related to CVE-2017-8823 (which was initially reported as remotely exploitable with no proof at all).
I went through the tor repository (not vidalia though) and read a bunch of conversations about some of the memory related bugs but none of those were exploitable either (exploitable as in remote execution, not a DoS) and most of the (not so many) bugs were actually logical bugs.
I really don't care what they decide to do with their project and honestly anything that can potentially improve the security of such a system is fine by me but I really think they're doing themselves and the language a disservice by communicating the way they do.
Also, as a side note, even with a C codebase there is SO MUCH you could (and should) do to minimize the impact of a vulnerability that the fact that some choose to present just rewriting code in a different language is not even funny.
Every change you make could be violating a some assumption made elsewhere, maybe even 20 years ago, and subtly break code at distance. C's type system doesn't carry much information, and is hostile to static analysis, which makes changes in large codebases difficult, laborious, and risky.
Rust is a linter and static analyzer cranked up to maximum. The whole language has been designed around having necessary information for static analysis easily available and reliable. Rust is built around disallowing or containing coding patterns that create dead-ends for static analysis. C never had this focus, so even trivial checks devolve into whole-program analysis and quickly hit undecidability (e.g. in Rust whenever you have &mut reference, you know for sure that it's valid, non-null, initialized, and that no other code anywhere can mutate it at the same time, and no other thread will even look at it. In C when you have a pointer to an object, eh, good luck!)
My biggest gripe with the Tor project is that it is so slow.
I don't think merely moving to Rust makes Tor faster either. And I am also not entirely convinced that Rust is really better than C.
No one is claiming the new version is faster, only that it is safer.
Of course, technically, this problem is related to the quantity of high quality nodes :)
5 proxies does it even slower but would make attacks much more difficult.
Client: "Hi, some.web.site.example please, I want to talk HTTP and I assume you know how AES works and I've randomly picked these numbers to agree the AES key"
Server: "Hi, I do know AES and I've picked these other numbers so now we're good."
Included in the very same packet as that response from the server is the (now AES encrypted) first things the TLS server wants to say e.g. to prove who it is, and agree that it knows HTTP as well.
0RT is a (very dangerous, do not use unless you understand exactly what you're doing) extension for some niche applications where we can safely skip even this roundtrip, also included in TLS 1.3
This TLS handshake can only happen after the TCP handshake, right? So 1 rtt for TCP, + 1 rtt for TLS. 2 rtt total. (2.5 rtt for the server to start receiving actual data. 3 rtt for the client to receive the actual response.)
QUIC really wants to do discovery to figure out a better way to move the data and of course Tor doesn't want discovery that's the whole point, so these features are in tension, but that's not hard to resolve in Tor's favour from what I can see.
Reddit over their onion website is very snappy, and compared to accessing reddit over VPN it shows fewer issues with loading images/videos and less likely to be blocked off.
It would be nice if more websites were available as onion addresses (and I2P as well).
edit: also if the Tor browser (desktop and mobile) would ship with ublock origin bundled, that would further improve the experience (Brave browser Tor window compared to the Tor browser is a night and day difference)
It’s not supposed to be a primary browsing outlet nor a replacement for a VPN. It’s for specific use cases that need high protection. The tradeoff between speed and privacy for someone whistleblowing to a journalist, as an example, is completely reasonable.
Having too much bandwidth available to each participant would incentivize too much abuse. In my past experience, a Tor associated IP was already highly correlated with abuse (users trying to evade bans, create alternate accounts to break rules, and then of course the actual attacks on security).
Tor wants people to use the network for primary browsing because it helps mask the people that need the protection. The more people using the network, the better for everyone's anonymity.
They even have a whole "Outreach" section at https://community.torproject.org/outreach/
3 relays is the goldilocks number for speed vs privacy. Using less is not a tradeoff the usual user of Tor should make.
2 = risk of collusion between relays
3 = goldilocks default
4 = ... actually, you have more attack surface and you are more susceptible to fingerprinting because everybody else is using 3, so you're timings etc help identify you
So the default is 3 and nobody ought change it! Use 3 like everybody else.
The exception is .onion sites. TOR actually deliberately defaults to 6 hops when accessing .oninon sites - 3 to protect you and 3 to project the site.
Tor is slow because traffic is routed through multiple layers. The design priority is anonymity, not speed.
Also, using this kind of software without understanding how its works even just a little doesn't protect much of your privacy.
There are some trade-offs!
Changing that setting to 1 gives you weaker anonymity guarantees. Using multiple guards spreads your traffic across different IP addresses, making it harder for an adversary who controls a subset of the network to correlate your activity.
Reducing to a single guard concentrates all traffic through one point, increasing the chance that a hostile relay could observe a larger fraction of your streams...
If you're starting a brand new VPN company with ironclad ideals about privacy - are you going to be able to compete with state-run enterprises that can subsidize their own competing "businesses", on top of whatever coercive authority they possess to intervene in local small businesses?
But I wouldn't recommend it of course.
Well it's certainly not worse than c, and it's hard to argue it's as bad, so...
> I don't think merely moving to Rust makes Tor faster either.
It would be crazy to think switching languages would make a network protocol faster without some evidence of this.
Except in regards to having a proper standard (the standard from Ferrocene has significant issues), and to the size of the language and how easy it is to implement a compiler for.
There are a lot of differences and trade-offs.

For most people seeking anonymity via Tor network (whistleblowers, journalists, activists, etc.), paying a company who can then subsequently be compelled to hand over your information is a bad choice.
And in most other scenarios, Authentic8 is probably still a bad choice. If you require a FedRAMP-authorized service, then sure, look at Authentic8.
Do you like pattern matching in Rust? It is one of the features that Rust does decently well at.
I think perhaps cryptocurrency is worse than selling urine for its chemical properties, but the principle applies, money is just money
I remember reading that it’s better to register as an organization if you want to run an exit node.
If you want to help the network, you can run relays. That’s much safer. https://community.torproject.org/relay/
> now I have gigabit
You can host torrents to Linux isos to help. You’ll need to block some Chinese ASNs though. They use fake downloaders to detect peers. Like 99% of the traffic my node generated was that. Nodes from one ASN that do partial downloads over and over
Else hosting open map data tile server though I gather this can generate a lot of traffic
Or, if you're OK with a little discrimination (say you're colo hosted, not residential), but still want to avoid exit-relay-level attention, running guard/middle relays is helpful: https://community.torproject.org/relay/types-of-relays/
The change log in the arti repo (https://gitlab.torproject.org/tpo/core/arti/-/blob/main/CHAN...) shows a lot of recent development too- versions 1.6, 1.7 and 1.8 were released in the last 3 months and they talk about setting the foundations for larger features to come. All in all it seems like the decision worked out for the team.
The extra safety in the code base is nice, but this seems like a bigger deal.
This has been a long running project, and the Tor team clearly took their time to make it, as opposed to being a spur-of-the-moment change.
Does Rust have better portability than C?
Could you elaborate on that? macOS Sierra (released on 2016) on Intel macs is supported[1][2], which should allow for Macs from late 2009 onward to work. The Intel Mac build is no longer Tier 1 because the project no longer has access to CI machines for them, and 32-bit cross building is hampered by Xcode 14 not shipping the corresponding SDK[3].

> Portability has been far easier than C, though sometimes we're forced to deal with differences between operating systems. (For example, when we've had to get into the fine details of filesystem permissions, we've found that most everything we do takes different handling on Windows.)
Remember, we’re not talking about the language. We’re talking about the stdlib and the surrounding ecosystem. The Rust stdlib and third party libraries generally handle windows well, so the Tor developers don’t need to special case windows.
[snaps fingers]
N. Young
There are others like Go.
I think they made the choice based on ecosystem, performance and prior experience with C.
I see people complaining about Rust's lack of portability, and it is always some obsolete platform that has been dead for 20 years. Let's be serious, nobody is gonna run Tor on an old SGI workstation or Itanium server.
dont temp me with a good time and awesome weekend project!
https://github.com/llvm/llvm-project/tree/main/llvm/lib/Targ...
Also, the more heterogeneous it's a CPU architecture support, the least exploitable a service will be.
i686 should have died a long, long time ago.
In all seriousness, I guess you can make this argument if you only care about Windows/macOS, but the moment you run anything else I have to ask why, say, Linux deserves support but not other less-common platforms.
1) Development resources are finite.
2) Linux runs all of the world supercomputers, most of the internet infrastructure (server, routers, etc), most of the cellphones (Android), and lots of other things. Its global marketshare is way bigger than macOS and all the BSD put together.
I'd imagine the biggest cultural reason is that many Rust developers were C developers who had a reason to find something better, but still scoff at garbage collection, large runtimes, etc. They probably have a lot more Rust expertise in their circle.
Another technical reason is that they were trying to replace their C code with Rust in bits and pieces before they went with a full rewrite. I don't know about Go, but this is something ergonomically doable in Rust.
I like loose type systems for some quick scripting, but I started to adopt Rust for many of my personal projects because I find it's so much easier to get back into a project after a year when there are good type system guard rails.
I've never had to do anything unusual with building, but I thought the "almost-ststically-compiled" thing was somewhere Go and Rust were almost identical.
Your parent is saying that, while what you say is true for Rust and Go code themselves, in practice, it is less true for Rust, because Rust code tends to call into C code more than Go code does, and Rust doesn't always statically link to that C code by default.
Also Rust has a lot more inherent safety features than go.
(I think Go is great and its my primary language)
That said, since they use Firefox this bridge has already been burned.

and better funded.
and easier to find devs.
Also, just because it's part of Google doesn't make go better funded. Theyd probably be fine killing go.
Definitely easier to learn though :P
I'm willing to be Rust suck a ton more to hire devs. Since, as we both agree, Go is easy to learn. Any C#, PHP or Java dev can get going with Go in not time.
But it's never going to surpass Go which is owned by a 4 trillion dollar conglomerate.
Machines will generate all the code, test that it works according to spec, you only need a vague notion of what is succint (do you just implement some existing trait?), what is typical (do you use index based data structures? do you simply use a Box, do you need Rc? Where should you use Optional?, do you want to use RefCell to make it mutable and so on), what is concise (just macro expand?), what is the correct type to use so you can warn the machine to re-adjust itself.
Personally I don't use Rust, I don't want to learn everything about Rust. It is the new enterprise Java boilerplate BS of our time.
So instead of running people through that ordeal, let them write the specs and machines should write the verbose boilerplate so the code is so called "safe" and concise without giving up too much.
I think "you should never do a full rewrite" is something of a reactionary response to the juvenile idea new devs and interns get every now and then. But sometimes, a rewrite really is a good idea.
But in this case, per the announcement ( https://blog.torproject.org/announcing-arti/ ), the reasons are pretty convincing. The major reasons are, unsurprisingly, all around memory safety.
The project was a virtual training simulation for a submarine cockpit, first in Blender Game Engine. With support for BGE being deprecated, I was tasked to find an alternative engine and to port the work. (I'm very proud my research pointed to Godot- this was during the Godot 2 era).
There was a lot of interest in the project, but my internship was coming to an end and they decided to port it to Amazon Lumberyard for fear of Godot's longevity and support. They didn't want to be left "waiting for Godot". The final task I took on was to document the project, to make that transition easier for whoever came next.
I've tried compiling large projects in Rust in a VM (8GB) and I've run out of memory whereas I am sure a C/C++ large project of a similar size wouldn't run out of memory. A lot of this tooling I had to compile myself because it wasn't available for my Linux distro (Debian 12 at the time).
A lot of the tooling reminds me of NPM, and after spending a huge amount of my time fighting with NPM, I actually prefer the way C/C++/CMake handles stuff.
I also don't like the language. I do personal stuff in C++ and I found Rust really irritating when learning the language (the return rules are weird) and just gave up with it.
For me, I had a very good experience rewriting a project in Rust (from Python). It was just an improvement in every regard (the project was easier to build and distribute, it was a good opportunity to rearchitect it, and the code ended up 20k times faster.) So, I have the opposite feeling when I see titles like these.
I also feel the opposite about the tooling. For me, cmake, npm, pip, maven, etc. all live in this realm where any invocation could become a time purgatory. The big thing that makes me like Rust is that I've never had that experience with cargo. (In fact, pip was the primary motivation to move away from Python to Rust. Everything else was just nice.)
I'm not saying this to convince you to feel otherwise, I just wanted to offer how I felt about the same topics. I grew up with C and Java, but Rust clicked after I read SICP and followed along in Racket. I could probably fill a page of small grievances about Rust's syntax if I had to.
Anyone that been on a "rewrite" knows that often the end result will look like the previous implementation but in <new thing>.
So what I see is a lot of development effort to re-solve problems that have already been solved. I think Ubuntu did this with the core-utils recently (I don't keep up with the Linux dramas as there is a new one every week and tbh it isn't interesting a lot of the time). They ended up causing bunch of issues that I believe were already fixed years ago.
There are issues with things in Linux land that have been issues for years and haven't been resolved and I feel that development effort would have probably been better spent there. I don't pay canonical employees though, so I guess I don't get to decide.
This is a common issue on large C++ projects for users with limited resources. You typically have to tinker with build settings and use a different linker etc.. to get the project building without OOMing.
> A lot of the tooling reminds me of NPM
My feeling is that you'd have the same criticism about a lot of other modern ecosystems because they allow you to pull dependencies easily. With things like vcpkg, that's also possible in C++ but even without it: nothing stops the same behavior of importing "random" code from the internet.
I use vendor directory in my C++ project and and git submodules and I've got a build that works cross platform. The biggest issue I ran into was MinGW and GCC implement the FileSystem library differently (I don't know why). It wasn't too difficult to fix.
I guess you and me live different lives because I have spent far more time messing with ancient C/C++/CMake/Automake/Autoconf/configure/just have this particular .so file in this particular spot/copy some guys entire machine because this project only builds there/learn and entirely different language just to write build files (CMake sucks and 5 other alternatives are just lipstick on a pig) etc. etc.
I am of the opinion that half of Rusts success is based on that fact that C/C++'s tooling is annoying and ancient. People want to write code not mess with build envs.
I am a hobbyist C/C++ developer and have a intermediate size code base that builds on Linux, Windows (MinGW and MSVC) and MacOS and I didn't do anything particularly special. What I did do is setup CI early on in my project. So I had to fix any issues as I went along.
What it is going to cause is having to learn a bunch of new tooling which I have to somehow to get behaving on my Debian box, because a particular tool that I will need to compile from source will have a bunch of Rust dependencies.
I've already run into this BTW, where I wanted to compile something in Rust and it needed a third party task runner called "just". So I then needed to work out how to install/compile "just" to follow the build instructions.
Why they needed yet another task runner, when I am pretty sure make would have been fine, is beyond me.
> But other people's project are not going to stop adopt new tech stack because how you feel about it.
I don't expect them to. That doesn't mean I can't comment on the matter.
RE: NPM, you have a right to a preference of course. I certainly don't miss the times 20 years ago when pulling in a library into a C++ project was a two-week project in itself. make and CMake work perfect right up until they don't and the last 2% cost you 98% of the time. Strategically speaking, using make/CMake is simply unjustified risk. But this is of course always written off as "skill issue!" which I gave up arguing against because the arguers apparently have never hit the dark corners. I have. I am better with Just and Cargo. And Elixir's mix / hex.
What you like as a language (or syntax) and what you roll your eyes at are obviously not technological or merit-based arguments. "Weird" I can't quite place as an argument either.
Use what you like. We all do the same. The original article lists good arguments in favor of Rust. Seems like a good case of "use the right tool for the job" to me.
I've lost countless hours having to get the rube goldberg machine of npm, jest, typescript, ts-jest and other things to work together. In contrast when I was learning OpenGL/Vulkan and general 3d programming, I decided to bite the bullet and just do C++ from the start as that was what all the books/examples were in. I had been told by countless people how hard it all was and how terrible the build systems were. I don't agree, I think the JS ecosystem is far worse than make and CMake. Now I am already an experienced programmer that already knew C# and Java, maybe that helped as they have many of the same concepts as C++.
Now I did buy and read a book on CMake and I did read the C++ 11 book by Bjarne Stroustrup (I found it second hand on ebay I think).
> What you like as a language (or syntax) and what you roll your eyes at are obviously not technological or merit-based arguments.
They aren't. What I am trying to convey is that it feels like a lot of things are done because it is the new shiny thing and it is good for resume/CV padding.
> "Weird" I can't quite place as an argument either.
The return keyword is optional IIRC in some circumstances. I think that is weird. I think I stopped there because I just wasn't enjoying learning it and there are zero jobs in my area of it.

The issue is that I think it (Rust) is going to worm it way everywhere and I will be forced to deal with it.
I don't _hate_ them or anything. They are super solid tools and I have derived a lot of value out of them in a previous life. But they leave a lot of room for overly clever humans to abuse them and make life hard for the next guy. Which is exactly how I was exposed to them, dozens of times.
The downfall of all flexible tools or PLs is that people start using them in those obscure and terrible ways. Not the fault of the tools or the PLs.
If you can control 100% of the surface where you are exposed to make/CMake then that puts you in a fairly rare position and you are right to make full use of it! Go for it. Deep work and deep skills are sorely needed in our area. I am rooting for you. :)

Help me understand the actual technical criticism buried in the "worm its way everywhere", please. And in the "it's good for CV/Resume padding" statement as well.
It's a strange thing to say and it smells like a personal vendetta which is weirdly common on HN about Rust and to this day I have no idea why even though I have asked many people directly.
Rust has objective technical merits and many smart devs have documented those in their blogs -- journeys on rewrites or green-field projects, databases, network tools (like OP), and even others. Big companies do studies and prove less memory safety bugs over the course of months or years of tests. The Linux kernel devs (not unanimously) have agreed that Rust should no longer have experimental status there recently -- and people are starting to write Linux drivers in Rust and they work.
I am honestly not sure what would satisfy the people who seem to hate Rust so passionately. I guess it announcing full disband and a public apology that it ever existed? Yes this is a bit of a sarcastic question but really, I can't seem to find a place on the internet where people peacefully discuss this particular topic. (I have seen civil exchanges here on HN of course, and I love them. But most of the civil detractors ultimately simply admit they don't have a use for Rust. Again, that is very fair and valid but it is not an actual criticism towards any tech.)
I don't understand why many people on here say "humans", instead of people.
What you are complaining about is abuse of tools/language features. This can happen in any language.
> Help me understand the actual technical criticism buried in the "worm its way everywhere", please. And in the "it's good for CV/Resume padding" statement as well.
They are self explanatory. I don't like it when someone does this stupid game of not understanding common idioms.
> It's a strange thing to say and it smells like a personal vendetta which is weirdly common on HN about Rust and to this day I have no idea why even though I have asked many people directly.
It isn't. What typically happens is that a tool lets call it "Y" get used everywhere to the point where you cannot use "X" without "Y". This happened to JavaScript. I used to be able to download a script and put it in say /lib in a project and not need a dependency manager at all. Now many libraries are difficult to install and download standalone because they assume you are using something like npm, pnpm, yarn or similar.

Just because <large company> does something and says something is true doesn't mean it is or is suitable for everyone. I have worked at some <large companies> as a contractor and often many of the people in that building do not agree with the studies.
I was working at a large company that rewrote all significant portions of their codebase in another language. There was almost no benefit and it cost millions. I was quite happy to take their money as a contractor, but it was a waste of money. BTW they never fully transitioned over to the new codebase.
> The Linux kernel devs (not unanimously) have agreed that Rust should no longer have experimental status there recently -- and people are starting to write Linux drivers in Rust and they work.
So I will need any additional toolchain to build Linux drivers. This is what is meant by "worming its way in". I have done a LFS build and it takes a long time to get everything built as it is.

You are making assumptions that I hate Rust. I don't. I just don't care for it.
What I don't like is hype and this constant cycle of the IT industry deciding that everything has to be rewritten again in <new thing> because it is trendy.
1. Rewrite each C file in Rust as a 1:1 mapping.
2. Rewrite the Rust to make it idiomatic.
3. Start making structural changes.
You can choose to write Rust with fewer external crates or vendor them like you would with c++ that is a dev choice.
Having more choices is better.
It's simply a way to be able to move at a reasonable speed is how I see it.
What matters is how the project is planned and implemented.
Typically, complete rewrites that halt all feature development and fail to achieve feature parity is a recipe for disaster. On the other hand, balancing the work for feature/regular maintenance and rewrite and gradually achieving feature parity before rolling things out has worked well.
A complete rewrite made sense.
