How Bisqwit makes programming videos [screencast / C++14] 

Shawn Key Same he is never shouting or using loud music in his videos

I just read this in Bisqwit's voice.

if thats true then you must be listening this at 1.5x speed

I thought for the longest time it was a digital voice. Then I saw a video that showed him talking, and I thought "oh snap! That's just his accent!"

I was like "omg he's speaking about me!" hahaha

***** Bisqwit is so inspiring

You gotta be a real nerd to name your account "memcpy" :D

+Bisqwit i fixed my google+ permission setting , can you re reply your answer to my comment ? Also can i have a copy of your *.spc music collection?

Thanks!

Iván Cea I feel like cheated too :D But it was good. I was compering myself to computer software all the time :D haha. Because of that I'm leveled up :)

Me too!!! I literally thought he was an absolute programming beast!!!!

What does this citation mean?

It is a reference to a well-known movie. Why though, I don't know.

MobsterSquirrel As in this video? , ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-h37xb8YkMJ4.html Although this is in reality more a mud-like game.

Sorry Bisqwit it was rude of my part not knowing about this video! Sorry and Thank you :)

I like your second idea. The reason why I didn't use the first version is because I wanted to limit the scope of the temporary std::string out of principle. Also, I may not have remembered that std::getline returns something useful. Namely, it returns a reference to the stream. And I may not have remembered that basic_stream has an operator bool() that does something useful.

xbuster17 I had no idea Top Gear had such amazing music either! It just came up randomly when I was looking for a song-set that would give me good background music when I play the asciibetically last song in that list. The SMRPG track that plays for the second half of this video also came up randomly -- it was a lucky accident -- so I left it playing on the background for the rest of the video. If none of the first five random samplings had been a good song, I would have covertly faded in some other song off-screen. Many years ago I used to write a blog. I called it "diary" at the time, because "blog" was not a hot word in the web yet. Sometimes in that blog I posted my observations of particular VGM tracks (mostly NSF tracks) that I had been listening to. Perhaps some day I might resurface some of those thoughts in a video. It might be hard to do that and dodge copyright missiles though. Thank you for the feedback!

I have produced and customized my own tools for the purpose, but cnee is one of those commonly available tools, and I used it in the 75000 subscribers demo.

I suggest learn some linux tools. I am sure there is a way to use a text file as keyboard input with a short delay btw characters.

I do use a ssh key. However, this was a virtual machine created just for the purpose of this video, and the keys were not set up.

That sounded like proper Finnish hahaha

vexe Thank you for the kind comment. As for "how to do X or implement Y", haven't I been doing exactly that? Though I admit on the fast-forwarded part (as in, type stuff way faster than a normal design process would be), but that's mostly because I believe more in the wisdom of inspiring people to do stuff and giving them reference material _if_ they need to look it up, than giving a step-1-do-this-step-2-do-that tutorial that just leads to parroting, which programming really is not about. And that's because of my own background and principle. I believe in "do others as you would like them to do to you": I've been reading a _lot_ of source code -- it's my hobby -- but I just don't have the patience to watch any how-to videos or lectures. I make videos that I would like to watch. In any case, I thank you for your feedback. I will try to adjust towards that direction anyhow, because there is a lot of demand for it.

Thanks for your reply. Of course you're doing the "how to do X and Y" I should have been more clearer. I think it is beneficial to see the non-edited version of things, cause it shows viewers how you deal with errors or bugs when they occur, and so we get insight into how the 'pro' thinks ;) Teaching concepts, giving deep understanding to how some things work has great value! unfortunately you might not have time to fit that in a fast-forwarded video, is what I'm saying. Another valuable thing a man in your position (someone who can influence others) can take advantage of, is to debunk some of the modern programming methodologies, such as programming in very high level abstractions, OOP and all its nonsense, focusing on objects and not the data, modeling data around code and not the other way around, etc. Since you're low-level I'm sure you know what I'm mean lol. Modern conventions have so many bad implications, they give the impression that you could program without having an understanding of hardware and how things work, how much each line of code costs and what it does behind the scenes etc this obscures communication between the programmer and the machine, which means we forget what we originally do, which is to solve problems by giving instructions to a machine, not design premature lame UML diagrams or sketch object hierarchies etc. This topic is hot, it might cause some flame wars in the comments lol but imo it's worth talking about, since there's so much intelligent programmers fall into this, cause it's what they're exposed to in college. Thanks!

vexe Thank you for your feedback! It's certainly something to think about. However there is no "non-edited version", as you learn from my video. Whatever ends up being the final programming video is specifically crafted for that purpose from the very beginning, long after the actual programming work has been done, debugged and completed. I do not have a desktop recorder running when I program normally, nor would it be feasible in any manner: I simply do not have a computer that I could desktop-record, at a reasonable framerate, and without slowing down the system to crawl. The setup that you see in this video is a virtual machine running on a quadcore server because of that very reason. And there's also the problem that nowadays I'm bad at focusing at a task. I might jump between a programming window or two, IRC, skype, email, entertainment, and away-from-keyboard every so often. Stitching together the moments when I do actually program, let alone adding meaningful narration to it in postprocess, would be an enormous undertaking. Much more so than what I'm already doing by now.

Totally understand, video editing is pure pain. I still think it's beneficial to many if you speak about your programming style/methodologies in general; what patterns you use in your codes the most, how you structure your programs, data layout, what you think of the so called 'modern' programming methods etc. Just my two cents. Cheers!

Nevermind I know see your comment, Nice

That would be Macopix.

***** I didn't quite understand your X question. The distribution is Debian GNU/Linux [testing branch].

Thanks!

***** It is a good point. Mainly what I mean is that even though I produced the video in kdenlive (which is a free video editor), the source video that was recorded from QEmu was included verbatim without any cuts.

As well as “sort -R”. I did not know of either when I made this video, but it does not matter. The point of this video is not to make a cool utility. It was just a plot device to get to the actual point which is my programming video production workflow.

Simply he is an ordinary bouncer!

+Cleaver Games By PBR rendering engine, are you referring to pbrt, the one that is introduced in the book Physically Based Rendering From Theory To Implementation? No, I haven't tinkered with the engine, but I have been reading the book.

+Bisqwit yeah i mean physically based rendering, i didn't know about that book ñ, i will read it

Tudorgeable I use search (^K^F) a lot to find a word or a sequence of letters near the location that I want to go. Sometimes I use ctrl-E (end) to go to the end of line that has a similar length to the horizontal position I want to go on another line. I also use ctrl-G (parenthesis matching) to jump around in the code. For vertical navigation, I mostly use arrow keys, pageup, pagedown and search, but for horizontal movement, I try to minimize the number of arrow keys I need to press. Other than that, I don't think there's anything interesting in the way I type. Mind you though, my way of typing is not the standard "10-finger system" (touch typing). It's something I have learned myself. My right hand tends to move while typing a lot more than my left hand, swivelling around the wrist, and the finger I hit a key with is whichever in either hand that is nearmost to they key at the moment (or so I hope; at least it's true that it's not always the same finger for the same key).

Bisqwit Right, so you're focused on typing exactly what you're thinking than how you do it, no wonder you type those terminal commands so fast (I am slow with special characters). Right now I'm trying to make sense of your qbasic 3D engine. It's pretty hard as a newbie to understand directly from source code. I know you've learned a lot from reading source code but I don't think I am at that level yet. I've done some qbasic when I was 12 for a short period but that was it. I am 19 now and I want to learn coding (in general). Do you have some influential sources of information, other than your very nice videos of course, to recommend for a beginner like me?

Tudorgeable Also, the numerous only-few-word copypastes and home&begin navigations you see in most of my videos are all algorithmically generated. There's only a few videos on my channel in which I am actually typing myself, including the first half of this video that you commented on. As for influential sources of information to recommend to a beginner, no I'm afraid I have nothing on that regard at the moment. Ï'll get back to this thread if I think of something.

I was using X forwarding with SSH to run QEMU from a Linux server on a Windows machine, and within that QEMU, a Windows 7 installation was running. The desktop you see in the video is this virtual Windows 7 machine. In _that_ Windows 7 installation, because I hadn't installed any browser in it, I was using X forwarding with SSH to run Firefox from the said Linux server on the said virtual Windows 7 desktop. This sort of inception stuff somewhat becomes a second nature once it loses its novelty. It's only when you try to explain it that it becomes complicated.

+Bisqwit Interesting, my personal experience of X forwarding has always been incredibly laggy (But I was running emacs). If the only reason you use windows is to ssh into a linux server, why not ditch the long boot times and price of windows and just run linux?

X forwarding does introduce considerable lag, but enabling compression in SSH mitigates it a great deal. The answer to your question is that I don't wish to wipe out preinstalled Windows systems in laptops. I don't buy Windows, but I have acquired several used laptops with Windows preinstalled.

+Bisqwit I see, any reason to keep them there?

Power management, hibernation and stuff, and utilization of the various priorietary hardware are usually done better in Windows, I think. I could be wrong. Also, Steam games.

Orson Peters I have (more often) used Cygwin X server + X11 forwarding, and (less often) alternatively Xming + nxproxy. However, to answer your actual question "what do I use to _connect to Linux machine_", it's SSH.

List file parser? You can find it in the repositories of many of the projects of my videos, for example: github.com/bisqwit/compiler_series/tree/master/ep6/dostools/ Note that the file contains raw 8-bit characters (including nuls). This tends to confuse a lot of text editors and text file viewers.

In my (passing) experience Node makes development easy and fast but requires excessive resources at runtime, such as lots of RAM or disk space.

Look up “bisqwit that editor” in a search engine. The last IDE that I used in DOS was RHIDE, but I liked the Turbo Pascal / Borland C++ IDE better. In modern programming, I don’t use an IDE at all.

+Naburi It's just an editor, not an IDE. You have to run compilers and programs separately.

Oh! I see. Sorry. Thanks for answering! :D

No, I do video editing also on Linux, and video recording happens through homebrew software (or DOSBox, also run on Linux). I use Windows in desktops because it came preinstalled with the laptops I have received from various sources, and I see it as a waste to replace them with Linux.

Franc[e]sco wouldnt this tie you down to always needing a network connection in order to get work done? I just cant wrap my head around this decision but to each their own :o Also curious about the attachment to borland's compiler, is it just familiarity? Or is there a performance benefit you enjoy? :3

What tool do you use to edit video on Linux? I've found literally every Linux video editor I've tried (half a dozen or so) to have some major show-stopping bug. I'd love to overcome this, though.

Jacob Rau this might sound weird but have you tried Blender? No GPU acceleration so rendering takes time, but otherwise it gets the job done.

Bob Magyar Fast prototyping, does not need separate compilation. I'm more fluent in PHP than I am in Perl or Python or Ruby.

I suppose you are talking about the font size. You can use the -fn option to choose a font. See “man xterm” for xterm options. See xlsfonts, xfontsel, and fc-list for the list of available fonts in your system.

@@Bisqwit Thanks! I really wanted to know this info for a while!

​@@Bisqwit But I have a few last questions if you don't mind answering. What font are you using in the video? How'd you make it a larger version of fixed, and would it possible for me to see your .Xresources file so I could have a reference as to how my .Xresouces file should be?

In this video I used a virtual machine that I hastily configured for presentation purposes. It’s not my actual desktop. I think I downloaded a VGA font from the Internet by google searching it. I did not use a .Xresources file, but .bat files that launch xterm with the desired font options (like -fn VGA16 or something similar to that effect).

I don’t really use stackoverflow unless it comes up in web search results. Also this video was made in a virtual machine that I installed just for this video.

No, they only specify the order. Additionally, the definitions file may refer to these numbers and say e.g. “in phase 20, scroll the window so that 10 lines are visible on top of the cursor” or “right before beginning phase 100, delay 3 seconds without doing anything”.

Bisqwit Okay, thanks!

Botika Kovács I've just finish a prototype of text typer supporting colors for keywords thanks to your tip into ncurses, I hope that soon enough I might be able to create something near the Joel's text editor.

Dhust Yay, this time your comment is actually repliable. Your previous one was not (and that's why Botika's comment was not a reply to yours, but a separate one). I have said it before and I say it now: *If you want me to reply, please make sure you don't disable replies to your comments* in your Google+ privacy settings (it might be hidden as something like "allow others to post on your wall"). Right now I can't even _find_ your original post. Did you delete it? Anyway, good luck and have fun writing an editor. Writing an editor was actually one of my very first programming challenges I did on Linux, back in the 1990s, when I had just started learning C. There are so many ways to do it, from designing the way the data is stored, to how the screen is refreshed and so on. I think the version that I wrote in the mid-90s for Linux used a system with two standalone vectors, where the part of the file before the cursor was stored normally in the first vector, and the part of the file after the cursor was stored _backwards_ in the second vector. That way either vector only ever needed to grow/shrink at the end, never in the beginning, which means that insertions and deletions never require mass moves of data in memory. A friend of mine, who was like a guru to me when it comes to programming or any technology at all, suggested this system to me, and I thought that all "real" editors in the world do that. In the end -- my memory is hazy on this and I don't think I still have a copy -- I think my editor was plagued with all kinds of mysterious bugs and random crashes, which led me to abandon the project eventually. Also I never liked working with ncurses, and I still don't. I like Slang much better. The editor that I created much more recently for DOS uses a vector of vectors instead. The outer vectors store each line of the file, and the inner vectors store character-color pairs for all characters on a single line. Because I'm using 16-bit sizes, that's where the limit of 65535 lines per file, and 65535 characters per line, comes in this editor. I _began_ with writing a gap buffer implementation, but I found that to be a too inconvenient design to work with on segmented memory, so I switched. I think most editors today use something called a "gap buffer". Emacs uses a "rope" instead. Some editors do what I did with the vector of vectors, but use a doubly-linked list for the outer vector instead.

Bisqwit Yes... I'm a subscriber to your channel for some time, So I already knew about the google+ thing, but man my config was like "who can reply my posts" - everyone. So I dint notice the that I ACTUALLY have to include your username there, I'm so sorry for that., dint want to make you repeat that. About the editor: Again, THANKS for sharing the experience, I'll look into Slang too and then try to write a complete editor, but i think that the hardest thing will be the keywords colors to work nice. I got some text inputter working but I dont think I did is the right way to color the keywords... I wanted to write in pure C code but that would take more time for me, so I used C++ STL to help. Your videos teach me a lot of cool things, I always liked the hardware level programming and I always want to learn more, so I found your channel inspiring. So thanks again for the tips with the text editor and stuff.

+Dhust, how did your writing of editor go?

Hey, thanks for asking! Unfortunately I didn't push that project ahead. But since then, I created a Chip8 interpreter and ported it to Android ( github.com/dhustkoder/XChip your Chip8 video helped me at the time). The project is much bigger than needs to be. But I wanted to practice library design, make it customizable and implemented sound/video/input plugins. Now, I'm writing a Gameboy emulator without the OOP model or C++ libraries/exceptions. Just libc and SDL, practcing 'data oriented design' and how C++11 can be of help there.

I could have used sort -R or many other options. But the point of this video was not the tool to begin with. The tool was just a plot device so that I could make a video about the actual topic, which is in the video title.

@@Bisqwit thanks I should have read the description before commenting

Top Gear title theme, as indicated on screen a bit earlier in the window where the command is running that plays those files.

I used the preinstalled Windows in that laptop because I did not want to deal with problems with finding Linux drivers for possible proprietary hardware / unorthodox solutions / missing features, that often may come up with laptops.

+Jon Renner Yes, I am. Stuff takes time.

r16815 I use the same editor on a daily basis, for everything that involves text editing, not only programming (e.g. write emails, essays, and articles). I've been using it for more than 15 years, and muscle memory won't let me use anything else. I'm aware that editors with more features are available, but I'm also perfectly happy with joe. I believe that +Bisqwit is in a similar situation.

r16815 I don't think I'm going to do a video on Joe, but I can share you the history. My first experiences with a fullscreen editor were with QBasic and the MS-DOS Editor. Soon around the same time, I began learning Turbo Pascal. The Turbo Pascal IDE uses keyboard bindings that are derived from Wordstar. Because Turbo Pascal was my ticket into making quick and efficient EXE files (especially in comparison to QuickBASIC), I learned to use the TP editor efficiently, and I became accustomed to the Wordstar bindings. For non-programming editing, I used mostly either MS-DOS Editor or QEdit. I did not know C back then. When I upgraded to Borland Pascal, I also made some scraping contact with Borland C++ and Microsoft's QuickC, but I actually disliked C strongly. Somehow in particular the pointer syntax in C seemed reverse and stupid in my opinion. I had a fundamental misunderstanding or two there. A year or two later when I began learning Linux, Joe was the only editor that came out-of-the-box compatible with the Wordstar bindings. None did work with the MS-DOS Editor inputs, as shift-arrows or shift-pageup/shift-pagedown were handled specially by the Linux kernel, I think. (I used Linux directly at the TTY level, without X, for many years, even as my primary "desktop".) Joe didn't even have syntax coloring at that time, but I could _work_ with it, because I was fluent with most of its keyboard bindings, and I could keep learning more. And that's how Joe became the editor in which I do everything, up until today. I'm also familiar with the input bindings of pico/nano, however inferior they might be, because they're used in Pine/Alpine, another ancient unix program I still use up to this day, and because it was often the only editor installed in servers I was managing at my work. And I know just enough of vi/vim to know how to exit. Similarly for emacs. If I run into a system that has nothing but vi/vim installed, and I need to edit some files, I use cat and sed. There was no Pascal compiler on Linux -- at least none that were even remotely as professional products as TP and didn't feel like gimmicks -- so I had to learn to use C, and I did. And when I did, I also began using C in Borland C++ (DOS), which led me to learn C++ as well. This happened about 20 years ago. For cscope, I had to google what it is. Clearly I haven't been needing it :-) I have used ctags a few times, because Joe has support for using the tag file. However, I can't be bothered to keep the tags file up to date, so it has been just a curiosity kind of thing.

This was just a virtual machine that I set up for the sake of this video. One of the myriad workarounds I used because none of my computers was fast enough for real-time desktop recording.

Maybe this Wiki will help you. wiki.osdev.org/Expanded_Main_Page

Which ones?

Nowadays I do. (Note the Linux machine in question is headless; it has only an old CRT, no GUI, no mouse.)

Ho, ok! Thanks for the reply!

+Freak Head english and finnish are supposedly two very different languages.

+M1zzu q I know, but that voice sounds like a damaged robot xD

maybe he is a robot?

He tried to speak "such" but missed. "Suchi, Sa, Suc... and finally such.

The font is either ‑misc-fixed-bold-r-normal‑‑15-140-75-75-c-90-iso10646-1 or ‑misc-fixed-bold-r‑*‑*-30-280-75-75-‑-iso10646-1, in this case probably the former, or some other character-set variant of it (such as iso8859-15).

If everyone was supposed to do using namespace std;, why would the language even have such a misfeature, forcing developers to circumvent it? There is a purpose and intention to every feature in the C++ language, and with namespaces the purpose is in differentiating symbols that come from user code from symbols that come from the standard library. The C++ standard library is very large, and not every developer can be expected to remember all symbols that exist in it. With namespaces, when you run into, say, std::iota or std::lexicographical_compare or std::sort or std::map, you know immediately on sight that this is something defined in the standard library. If you don't remember what it is, you know that you will find the answer in the library documentation (such as at en.cppreference.com). Without the std:: prefix, there is a moment of confusion when you aren't sure whether this symbol is possibly defined elsewhere in the program and you just missed it. After doing this systematically, it becomes the second nature. The minor inconvenience of your code being littered with std:: prefixes is minor compared to the benefit you get from doing this, and the benefit you give to other people who read your code. Additionally and perhaps even more importantly, the namespaces prevent there from arising nasty mixups and conflicts from user code and library code defining the same symbol (such as vector, list, or map). And now with C++11 and its "auto" keyword, the situations where you _need_ to repeat the std:: prefixes is even diminishing.

oh wow thanks for fast reply! c:

The strings for F1, UP, INS etc. are keyboard input sequences. On the PC platform, when the BIOS is asked to return the key that was pressed, special keys that are not character codes, such as F1 or the up arrow are returned as a sequence where the first byte is zero (your editor may show the zero byte as an inverted @ or a box or a question mark) and the second byte is a “scan code”, where its number value is important and its character representation is insignificant. For example, the up-arrow is 0 72 (or 00 48 in hexadecimal), so as a string it will appear as "\0H" or "@H" (nul characters cannot be entered in RU-vid comments so I used @ as a placeholder)). The slow-down sequences like DELAY8s include one or more of these special inputs (such as Alt-F, which does nothing in the editor so it can be used as an idle key) and a special sequence that begins with ÿÿ and is followed by a character code that instructs inputter.com to change its entry speed.

+Luong Kyanh He has a X-Server running in windows, so the X applications on his linux is started with a window in his windows machine. When he SSH's with the -Y option, he is tunnelling the X data via the ssh connection.

I am aware that the command I created at 4:55 is needlessly complicated, and could be replaced with: find /WWW/music/spc -name \*.spc | sort -R | tr '\12' '\0' | xargs -0 -L1 sh -c 'spcplay "$0" ﹤/dev/tty' However, I had temporarily forgotten about "sort -R" when I made this video, and it did make for a small enough example program to serve as a plot device.

לא רק. גם יש לו וודיוא מיוחד להסביר את ההתחלה.

Back when this video was made, none of my computers was fast enough to do desktop recording in real time, so I needed some crafty measures to make this video happen.

@@Bisqwit Oh... I didn't notice the upload date. I came from card in one of latest videos. Thanks for quick response anyways!

Maybe. Not sure why I didn't think of it here. But I use ctrl-a and ctrl-b lots in editing so I don't like to edit under screen/tmux, because they use those keys respectively as command keys.

Bisqwit I think it can be redefined in tmux.

As can be in screen, but I prefer not having to learn a new set of hotkeys for the same software on every machine I work on.

Which files am I typing every time?

Didn't you say that everytime you start a new project you copy those same files (at which point you proceed to cp a few .php and apache files, I believe). Roughly 7:50 mark.

So if I'm copying them I'm not typing them from scratch, right?

I mean, if you always copy "those same files" (which might be something I misunderstood) I'd rather write a quick bash file to do it all for me and run one line instead of N-many lines.

I usually take them from the most recent project, where they have my most recent edits to them. So it would be a bit different each time. Considering I only do this like two or seven times in a year, it's not that much a big deal.

Usually when I make videos I use things specially designed for video production, readability etc. It is (sometimes very) different than what I use normally.

Kianou The window sitter is a program called MaCoPix. You can download it here: rosegray.sakura.ne.jp/macopix/index-e.html

Bisqwit Ah thankyou :)

Yes, that is exactly the same idea.

ShadowMassacr13 even for someone who has been writing code for 15 years or so on a fairly regular basis, there is still occasional need to check documentation or similar, and occasionally turning out to be a little off about something, ... not sure if anyone really fully internalizes the standard library (or OS libraries). though maybe some people have more reliable memory, dunno... in terms of peak output speed, I think around my upper limit is around 2kLOC/day or so, which if one assumes writing code for 10 hours, would work out to an average of around 18 seconds per line. per-year estimates tend to be a bit lower (if this were maintained, it would be around 0.73MLOC/yr, averages had tended more towards net code inflation of around 0.2 or 0.3 MLOC/yr). recent values have likely dropped a fair bit, as I haven't been doing as much coding (been working a lot more on other stuff, and currently lack any big high-level coding projects, instead working a lot more on electronics and similar, and code for controlling said electronics, which is nowhere near as much code).

Brendan Bohannon Wow that is a ton of code to me. I guess I'm just a slower coder, hopefully I can get that fast semi-soon.

ShadowMassacr13 I guess it depends. if I really get into it, typically if there is something compelling to work on, then can write code a bit faster. have noted that factors for speed are not as much about how quickly it can be typed, but more how much thinking is needed. things can be done a bit faster in cases where not as much thinking is needed (needing to think about things slows everything down). debugging time is also a factor, but in my case I suspect I haven't really been having too much trouble with bugs being difficult to track down, but this still happens occasionally. much of the rest of the time seems to be things like YT videos and online forums, or occasionally doing things IRL like soldering components to make circuit boards or similar.

+Brendan Bohannon Are these estimates from paid work? The biggest shock to me upon entering the professional world has been how little code I actually get to write. Most of my time is spent on meetings, e-mail, or dealing with all the various tools and enterprise infrastructure. I'd be very happy if I got to write even 100 lines of code a day!

+Brendan Bohannon "typically if there is something compelling to work on, then can write code a bit faster." - This is so true! I remember a hardware class I took back in school where our group was tasked with writing a 68K disassembler... In 68K assembly language. I thought about it all day, went home, and hammered out 4,000 lines in a sitting. It was one of the most engaging experiences of my life! I actually had to hold myself back and not complete the entire thing right there so that my teammates could still feel like they contributed, lol. In the professional world it seems rare to get a project that you can just 'do' like that.

Quote from video description: I am aware that the command I created at 4:55 is needlessly complicated, and could be replaced with: find /WWW/music/spc -name \*.spc | sort -R | tr '\12' '\0' | xargs -0 -L1 sh -c 'spcplay "$0" ﹤/dev/tty' However, I had temporarily forgotten about "sort -R" when I made this video, and it did make for a small enough example program to serve as a plot device.

multicoloredwiz It is called "estimation".

Counter_Sanic I'm just borrowing other people's recommendation: C++ Primer (ISBN 978-0321714114). I wouldn't know, I don't read many books. Sorry.

Counter_Sanic Scott Meyers has written many excellent C++ books, such as _Effective C++_ and _More Effective C++_ (they are a tad old now, but still quite relevant.) I haven't read _Effective Modern C++_ but I'm assuming it's also good, given his track record.
