Clone of Hacker News with modern design. Also: run global initializers. For others, this is the review that the OP seems to be speaking about: An Introduction to C & GUI Programming - Simon Lon is also good for beginners, especially it's easy understand content and beautiful typographic style. Let's get to it. This is why I think that debug mode, should be very different from release mode. It's definitely not an absolute beginners book though. How does this book compare with "21st Century C"? Along Modern C I found these modern(ish) C books: - C Programming: A Modern Approach, 2nd Edition by King. I have been meaning to learn the Plan 9 dialect of C but haven't gotten around to it. This book does not do this. Thorough. Ultimately this is one of the ultimate bikeshedding argument. Fascinating programmer. Buffer over runs, can be trickier, but I have plenty of tooling to find the issues. Is there a place to report errors? Still, why don't you use the right terminology? The fiddlyness of const type declarations is definitely one of my least favorite parts of const semantics in C and C++. But to be fair, it is far easier to find new languages and tools today than it was pre-internet. If you're not doing safety work, the Linux kernel is a great example of 'nice' modern C. https://github.com/BoschSensortec/BMP280_driver/blob/master/... Because there is nothing inherently modern about this code, this is how C has been written for decades if not from the very start (I think you will struggle to find patterns in this code that are not covered by KnR). Sure, except for the part where C is a language that uses English or English-based keywords, designed by native English speakers. I'm not sure learning by repeating the failures of the past is a very scalable practice... :-). If memory serves I even bought at least one item from a text ad on Google sometime around 2005 or 6. Excess verbiage for terminology isn't a panacea to confusion, in fact it can increase it. foo is a pointer to an int that is constant. It's not about moral goodness, it's about developer ergonomics. That's true, I forgot about that because the last controller I used had a bootrom that copied the booloader straight to RAM, so .data was already read-write and there was nothing to do. On top of that he gives many best-practice advice, that you could call "modern", as they are often violated in 20+ year old C code (and often by people who learned C in the 80's, in my experience). Especially if one browses with javascript disabled. I used k&r as my first C book. https://uefi.org/sites/default/files/resources/UEFI%20Spec%2... https://andrewkelley.me/post/unsafe-zig-safer-than-unsafe-ru... https://www.actian.com/analytic-database/vector-analytic-dat... https://gforge.inria.fr/frs/download.php/latestfile/5298/Mod... https://floooh.github.io/2018/06/17/handles-vs-pointers.html. That's nitpicky though. You could also look up "format", which gives one reference, to page 5, where the term is introduced but hardly even defined. Please point out where the poster "discredit[ed] the entire thing". By the very fact that this is a book, it presumes that the intended audience consists of visual learners. You can create pdf, xml, and epub from the same source. Many of the current standards committee members are active impediments to progress. Why don't you buy the bundle and throw away the digital versions (facepalm)? GCC 8 and above support C17, and there is a version available for Windows. Academics from École Polytechnique Fédérale de Lausanne (EPFL) disclosed a security vulnerability in Bluetooth that could potentially allow an attacker to spoof a remotely paired device, exposing over a billion of modern devices to hackers. At least it seems more consistent than anti-feminists being "reactionary" for the old times where we could make jokes about women but being offended by jokes about men. Reviews Review Policy. Namely this one: Though these can be reordered, it's clear they were intended to follow English. Displays recent stories from Hacker News. I really wish compilers had a -Wstandard and that warned on standard breaking things vs -Wall or -Wextra which has compiler specific junk like -Wparentheses, No, I basically want a W switch to warn only on potential buggy code (implicit-int, etc). Those were fun times! I learned C from K&R. I wish all C books had more chapters on this. Just wanted to tell you that I watched your stream and it was really good, I learned a lot. :-). The build environment is unixy enough to be able to build more tools from source using the classic ./configure; make; make install route (more or less, may need some modifications in the code). Insane take. For C I mostly agree, but from what I understand there's still a ton of new C++ being written and even replacing "legacy" alternative languages even if they provide advantages. about careers press advertise blog. > And despite that "distance" there is virtually no difference between C's and C++'s (and often Rust's) performance. Then someone told me that Odin has the same thing: https://odin-lang.org/docs/overview/#using-statement, They have lots of book publishing resources: https://www.ctan.org/topic/book-pub. I ended up giving up on the book for now, maybe I’ll pick it back up later or I’ll peruse your list. I too learned C from K&R and really loved it. plz recommend if you have more! Without that Rust's assembly looks a lot like C++'s and more like C's. can you be more specific about these practices? I think the best way to learn that stuff is by doing, get some ARM chip with an u-boot loader and dig into it, break it, see what code does etc... Obviously you need a good knowledge of C to begin with, and at least a basic understanding of assembly, so start with that if you're not there yet. C could have an optional bounds checking mode. A useful approach is to learn 95% of the language from K&R, and then refer to the newer standards for the incremental changes. It is that I have seen too many people come from higher level languages or with no programming knowledge and find K&R frustrating due to its assumption the reader is already a programmer in some other (1970s) language with a fundamental understanding of some programming concepts. What about the phrase do you find to be super confusing? So C hasn't been reflective of typical desktop/server CPUs for the last 30 years at least. And definitely do the projects to practice. I think you're leaving out the option that the person you're replying to has seen even worse bugs because they have better ideas of how to deal with random crashes than bisecting code changes. > Perhaps I should knock up a script to visit random sites with ads and maybe click on a few, in a container/vm. A refresh, 5 years later, would be useful, though. You get the power of Tex but producing modern looking stuff is IMO much easier than with Latex. Whether the const is applying to the "int" in some way or is an independent type specifier that applies to each declarator is pretty philosophical. > you actually put EFFORT in finding something. Regardless of the argument, that's an unkind, personally-attacking tone and doesn't seem necessary to your criticism. Can someone summarize how this book differs from: shameless self promotion "How I program C". Teaches a lot of practices that lead to obtuse brittle code riddled with security holes. People complain about things missing in Go that are technically not in C either, except it has a lot more batteries included stuff out of the box. Weird. Except that you'll be hard pressed to find a syscall without an accompanying C library. Eh? Feel free to join in because that’s one of the things I will be talking about. Instruction-level parallelism is par for the course in modern processors, many of which have hundreds of instructions executing at any given time. This extension displays the latest articles from Y Combinator's Hacker News (news.ycombinator.com). > Lots of deliberately bad C code. The issue with C is the silent issues like buffer overruns, i.e. I don't understand, why are the PDF documents specifying the C/C++ standards being sold for $$$ when I believe I was able to find them on the respective WG website? Who knows? The level of detail and nuance when using terminology here is used to match the context the terminology appears in. By John Hacker news@joplinglobe.com. For instance, if I'm just walking arena-allocated memory, the borrow checker does nothing for me. >I'm not sure there's really much of anything that it owes to C. The difference is that it’s well defined as two’s compliment overflow instead of UB. The main reason is that, it was a very dry read with various rules and syntax etc and I got bored looking at it quickly. It can assume that the programmer knows what they are doing. I think it's got a ways to go but I see some huge potential to offer such an improved experience that people would be stupid not to use it. It's missing three revisions of the language. people are very dismissive of this style and reject the idea you have to write any comments where the code is ‘self explanatory’, but I don’t care. How many people who are commenting are missing the point is hilarious. C17/C18 is a minimal "bugfix release" to C11, mostly standard clarifications. To be fair, I don't think I've ever seen a serious, hardcore programming book that looked nice. Both of which can cause memory issues very quickly. Personally I think it's really refreshing and made me appreciate C and lot more. PDF is usually good enough, but sometimes needs to be converted to other formats; you usually get best results going latex->epub than pdf->epub. Read, view comments, bookmark and share stories from the hacker news feed! I took it as "contradiction in terms", you can't be modern and C (incidentally, I love C). Just after you do learn it, stop and use something else. I was theoretically aware that there are people out there that don't use ad blockers, but I sure as heck didn't expect to find one on hackernews. There is no other book that covers the modern parts of the standard well. Runtime variable local arrays, designated initializers, restrict not. That has not been true in decades, if ever. I remember back in the day sites saying "click on the ads - it helps us" but I don't think that's a thing any more. The biggest problem C has is the standards committee. And the point is the double standard. https://web.archive.org/web/20181230041359if_/http://www.ope... https://old.reddit.com/r/embedded/comments/ilgyun/would_you_... https://web.archive.org/web/20200901014356/https://wiki.osde... https://github.com/safayetahmedatge/efitutorial. DEV. even if you program defensively and with a proper security model you're still opening up to the possibility of leaking your missile codes by accident because you committed bad code. Unless you absolutely have to. It's bad cosmetic. clang static analyzer and the one in Visual Studio), minimize dynamic allocation and pointer use. Thanks for the explanation. So there is no debate to be had there. Think operating systems, kernel modules, executables, dll's, and, etc. Seconded. 1. August 12, 2020 The Hacker News As software eats the world, the world faces a software security crisis. Building. Its undefined behavior, so the compiler is free to do all the checks that a language that doesn't let you write outside an array do. He has also written an article on how he writes the code comments [0]; I've been using Design, Why, and Teacher comments a lot in my last projects and they have been very helpful, especially if you come back to the project after a long time or introduce a coworker to the code base. I think it can be both, plus communication: communication to n00bs, to yourself in the future if you're really tired, etc. It's certainly not insular or community destroying - an accusation like that is simply hyperbolic. parenthetical was not that the author actually had a dim view of men. Beautiful. Not the OP, but for what it's worth, the overall flow of the book just didn't work for me. > C++ cribbed designated initializers from C, In a C++ designated initialization, members. I think the parent comment was less about the capability of Rust, but more about the overwhelming momentum that C has. 1. C is to modern hardware like the Intel 8086 is to an Intel Xeon Platinum. Humor doesn't have to be obvious to be good; and a magician doesn't have to ever give away the secrets of their illusions, no matter how loudly their audience cries out. Hello! And has never been updated ever since. Ah yes, I’ll file this between Deafeningly Silent and True Myth. For now the plan is simply to make them available online formatted for web, e-readers, and PDF, but thought is being given to formatting for print-on-demand. How does int describe an int? The terseness is one issue, but the security problem is that it implements strcpy at all without warning. Might you or someone else have a resource on learning how to do this? Since you mention typesetting: I am working on a volunteer project that is transcribing old, out of print books from the 1700s through early 1900s (all public domain). It doesn’t take me a lot of extra time to document the general idea behind a piece of code and it makes my future life and that of other devs reading the code so much easier it’s easily worth the effort to write these comments and keep them up to date. I agree. [DEV] Harmonic for Hacker News - A modern Hacker News client. EDIT: Besides, one of the electronic versions in the bundle is sold separately for $24. You've obviously never experienced random crashes where the best idea anyone has is to bisect code changes in production and see when the crashes stop. But if you're coming from something like Python or Java or JavaScript (or even no language at all) there are better options such as K N King's A Modern Approach. To clarify, by parent I was referring to the original commenter who made the parent comment to yours. It fuels an "us vs them" mentality, and doesn't win over any hearts nor minds. AFAIK, C11 threads are supported only in Linux. Is this a good resource for someone using it to improve their C skills, and not necessarily writing a lot of C? Can anyone recommend some of these for my background? In a typical microcontroller that's a copy from flash to ram. means that That's it. :), OS dev[1] has a full page on how to do this and more, as well as links to sample code, etc. It's strictly less work than a responsible unit test suite, and there's not much downside to getting some details wrong on this particular application. It's isomorphic, but you're right, I used an overly specific term. You can use the mingw distribution to get a GNU tool chain that compiles a standard windows EXE. Somewhat controversially, C permits you to define members multiple times, with the last definition taking precedence. A simple and modern Material Design influenced Hacker News reader Android app. Used it in college about 8 years ago. Hacker News is a social news website focusing on computer science and entrepreneurship. It is therefore inconsistent with pedagogical best practices. But obviously I'm not advocating comments that simply describe in words what the next line of code does mechanically, those are useless. > but I wouldn't expect anyone to write a brand new queuing system or database in C or C++ anymore given the alternative languages available. It makes his code very approachable, as well as providing an excellent model for complex projects. For me the value is in being able to read the comments first and get an idea of the structure of the code and the though process behind it, before actually having to interpret the code itself. This is true whether you buy the book directly from them or from a bookstore: > It's also worth noting that you are supporting a a small independent publisher that's DRM free, as well as supporting independent authors. This is a book about C in the context of the compiled variant, and has references to gcc and clang. I wonder if it used a publicly available style? I take it there is no C17 compliant compiler yet? The const qualification is in the type; it is not a direct attribute of foo, so putting the const closer to foo means nothing. I am sensing a confusion. That's why I say that the book errs by sticking to the game plan too rigidly. so, is javascript an interpreted language? I know what you're trying to say, because at least 95% of segmentation faults are easy to fix, but I take issue with this. > And the ergonomics of modern C++ look absolutely horrid compared to actual modern languages. Error handling, however, is generally present (or left out for brevity and noted). Indeed, declarators must have their postfix chain read first, left to right, then the prefix portions right to left. Given the author is German and lives in France for years, it could totally be a sarcasm to denounce the current situation. Not always obvious, but an ill formed access should not fail silently. Print and eBook editions of Modern C, Second Edition, can now be ordered from my publisher, Manning. Other, like buffer overruns, are easier to avoid with things like spans and ranged-for loops. The point is the C abstraction is lower level: give me memory, write to memory etc. I really enjoyed it, but it’s best supplemented with exposure to modern C syntax and an introduction to undefined behavior. ... list of "Top 9 Security and Risk Trends for 2020" putting a bold emphasis on the growing complexity and size of the modern threat landscape. I can imagine cost and long being adjectives for the noun int. I've been working on a side project that is essentially rebuilding Redis but in Ruby, only to learn how things work (. It all runs in the web / browser too with Webassembly. There are several C interpreters as well. It's not a good book, the author makes embarrassing mistakes to the point where you start questioning his programming knowledge. Everyone should evaluate whether the book (any book) works for their needs. void* hate built-in. That's all you really need to know to do stuff and it doesn't go into what malloc actually does under the hood. Other books could help to provide a more modern take on how to adapt the language to 2020, but the original K+R book is still the best way to really learn the language. In a compiler implementation, it's troublesome to enforce the order compared to processing a simple list and setting/checking flags in some data structure, diagnosing invalid duplicates or mutually exclusive situations. If you're not clicking on them it means nothing anyway, as far as I can tell. Unfortunately, these editors "Manning" do not want to sell the print version only, they sell you a bundle containing the printed book, an some digital versions: an "ebook", a "livebook" and whatnot. As for why the finalized versions cost money when the final draft is virtually identical all the time? I have it and flick through it whenever I want to remind myself about the dark corners I never mastered during the last 20 years of programming in C. As long as he's publishing under a CC license, it might be nice to release the LaTeX source as well. And as you say, without const, the same code is generated. I suspect this might be due to recent hacker news changes related to comments. Zed Shaw consistently shows he would rather hear the sound of his own voice and diminish things that are uninteresting to him rather than put in that work to become an expert on all facets of the topic he is claiming expertise. Posted by. Pair it with excellent notes by Steve Summit [2], and you don't need any other book to master C. No doubt K&R is second to none, but it only covers C89.
