Fun fact: Roller Coaster Tycoon was written in assembly. There was just a little bit of C code to glue the game into the Win32 API. To date, it's the only assembly program that I know which *deliberately* contains crashing. :)
Been programming for 3 years, it's amazing how Dave shows you what true mastery looks like while remaining incredible humble. Makes you think about what it really means to BE a programmer. You sir are an inspiring.
Even in fast mode, that clicky keyboard is a very distinct sound.. I would bet it's an original IBM model M or a close cousin.. the sound still makes me jealous and wish I still had my original AT keyboard.
Haha, ask me, I surely needn't tell - from 8-bit pixel graphics in 320x200 to software-rasterized vector line graphics to the first textured 3D after gouraud (looking at you, TIE Fighter) - to now graphics cards that do not only do global illumination in real-time but can also do raytracing, in real-time and hardware! The past 30+ years have been a hell of a ride! Though youngster would probably look at me like "old fart syndrome" XDDD
Getting MS-DOS 'for free' yet buying DR-DOS in the States (I live in Europe) was an adventure of its own. "Programmers paradise" was the nearest shop for me.... At 5000 miles distance.
Even for a modern C++ programmer, this gives a lot of insight to how programming was in the early 90s/late 80s. The commenting work is also very good! Learned some stuff I never knew about Windows.
I don't really get what he says though. Sounds like he's swallowing half of most words. And he is so C-centric (and also windows centric) that it hurts.
@@martysh1226 Well, Linux is even more C-centric. The old Windows API structures were originally defined in Pascal in the mid 1980s, largely taken from Xerox (very much like the first Lisa/Mac systems that were also written in Pascal). That's why we still use "PASCAL" calls on the ABI-level when writing Win32 code in C/C++ (although renamed STDCALL today, iirc). However, I did this in the 1990s without thinking much in either C or Pascal. I though in terms of assembly plain and simple.
Indeed, he is a machine. For a while I assumed he sped up the video, (there were some suspicious camera cuts, such as 22:30) but nope, he really does type code that fast. It looks impossible. I had to LOL several times. But he could have sped up his typing by 2% if he learned the keystroke for "delete previous word" rather than hitting the backspace character multiple times in a row.
I don't know but it looks pre recorded coding rather than live coding. The text cursor stops as he turns around to speak and also the blinking speed of that text cursor is fast (Like 2x - 3x or so). Also when he exit the nano editor, the directory is changed. I might be wrong on all these but yeah I noticed that.
@@cyberwaves I hear ya. Maybe someone with OCD can slow down the video and analyze the keystrokes, comparing them with what actually appears on screen.
@@TheNameOfJesus Did you really just use OCD as a synonym for "doing something detailed"? See, THIS is why people get annoyed at people just throwing around legitimately destructive mental health issues like OCD and lifelong, disabling neurodevelopmental diagnoses for fun.
Indeed,.. if you're at 3k when doing a 4k intro you're starting to cut into the musicians part of the space so better have all graphics and effects working at that point :D , honestly though this stuff he writes would probably be far smaller if he used the crinkler linker instead.
Watching Dave livecode is as relaxing as watching Bob Ross paint. I haven't done Win32 programming in over a decade, but this brought back some great memories.
Fascinating content, and Dave’s typing sounds like white noise since it’s so fast. That’s decades of time spent at a keyboard on display. Thanks for creating this!
I also grew up in the '80s but I was in Louisiana. As you might expect, things were not great for a computer nerd during those days. I had my Commodore 64, banging out BASIC scripts, but I lacked resources or a mentor that could take me to the next level. My guidance counselors, who didn't understand computers, didn't encourage me to go down that path for a career. I literally thought you could be a scientist or work in a store. Retail is what I ended up doing for 10 years, though I was always building my own PCs. I finally broke into the IT support business and never looked back. Still can't code very well though. I wish I had focused on it more when I was young. So if you are a young person, or a parent of one, and your child shows an inclination to learn programming, by all means support them and try to encourage them to learn as much as they can.
Argentina and TRS-80 (Models I and III) for me; not mine, for some mysterious reason they allowed me to use them in a retail shop. Luckily there was some documentation for the API calls for the TRS-DOS, and it had a debugger that allowed you to to step-by-step and basic disassembling. With that and a book on Z80 I ended up reverse-engineering the operating system when I was 14 years old. Good times.
When I wrote some assembly code in the early 90s I wouldn't have imagined that one day I'd be seeing someone's screen with 753,488,695,296 bytes of free space next to a 7,292 bytes assembly code. Also: insane assembly coding skills displayed in the 21st century.
@@alanhat5252 It's amazing how much space is out there!! Which is only in the dimensions that we know of... Mind boggling to think of how much is actually there just that we don't perceive it as being there as space! 🤯🤓
I love to watch a master at work, machinist, electritians, carpet layers, roofers ect. Most of this is so far over my head. the peak of my programing was a basic program to calculate the length of a bicycle spoke, took me a week. I got clear through this and hold you in awe!
Started a computer science course in 1966. At BU it was simply called programming, we used Dartmouth Timeshare BASIC. In my career the most sophisticated language I ever used was Pascal, GUI programming scared me. Recently, after retirement, I bought a few Raspberry PIs and learned Python. When I was at Digital Equipment Corp I taught their machine code and assembly language. All this has no value unless I want to start a UA-cam channel. I love your videos Dave, they bring back a lot of memories. BTW, my daughter was diagnosed with Autism but after years a tests it turned out to be CVI and I'm glad to say she's one of the few that has almost completely adapted out of the worst of it.
After the Tandy TRS-80 Color II (Trash-80) in 1985, Finally got a 386SX with DOS 5 in the mid-90s. Moved on to DOS 6.22. And then to Linux and FreeBSD in 1999. Dave, I forgive you for working for micro$0ft. And I greatly appreciate your current contributions to the free world. I've worked in IT support, Data Centers, and field work for the last 21 years. Cheers!
I had to do two double-takes when I read the title, first thinking something must be wrong, as I was sure I’d seen this video a week ago, and then confirming I actually read the title correctly. I thought your previous video was unbelievable enough, I was shocked you could go so low in windows, having to manage so much yourself, so to turn around and do the same things in ASM, I’m speechless. It’s truly amazing to see an entire program written this way, it feels so alien to anything I’ve seen before (and in a fifth the time it takes me to get a 6502 spitting out data through a serial connector no less)! You never fail to amaze, best of all is that you explain things as you go in a way that even I can follow along with, that’s saying something.
Oh the memories you brought back to this 73 yr old nerd. Started with assembler cutting my eye teeth with MASM. Enjoy your channel immensely Thanks Dave for another walk down memory lane.
You make that look so easy, the flood of memories from my windows 2.X days reminded me that nothing was easy back then. You had to really work for performance. Great demonstration of an ancient art, definitely a "Bob Ross" moment.
Im doing an education as Application Developer specialized on application development and im always impressed when someone writes in Assembly or still uses "old" languages. Keep it up!
Loved this! Brought back memories of my machine language work in 8080 in the mid-'70s. I couldn't afford an "OS" after building the IMSAI, so a friend gave me a copy of his Altair basic. I wrote a machine language program to search for the input instructions, as the IMSAI could be loaded from the front panel, find the input/output commands, and then I wrote a jump to my input/output to my devices (Altair basic was loaded with my homemade "Tarbell" tape interface). When I finally acquired an 'assembler' for the 8080 I thought I had died and gone to heaven! The best program I ever wrote on the IMSAI/8080 was a "BAUDOT to ASCII" converter so I could use ASCII on ham radio RTTY. (Today ASCII is ok on ham radio, but not back then! ) - And to think we had 1K boards back then plugged into our S-100 bus! Fun Stuff! BTW< who else do you know who started their career with Western Union as a teletype tech and finished (retired) with Cisco Systems !!
How I wanted an altair in 1975. Looked like those movie computers till I discovered a "computer store" by accident. The owner convinced me to get a SWTPC6800 with two buttons ON-OFF / RESET instead of flipping switches just to read a keyboard, to type code to read a cassette tape program etc. The swtpc6800 used a "BIOS" called MIKBUG which had code to read a serial keyboard, display to a serial monitor, load and save a program from and to a serial cassette tape machine, enter an address and type machine code in hex. I thought "who needs blisters on their fingers" suffered by many an altair user.
I have been a programming since this guy the 1970s ( I was maybe 14 when I first wrote some code,) and watching this guy bang out assembler code like he was typing an email is humbling :)
I started with the 8080a - in machine language and can still remember most of the codes! 40-7F were reg moves ,b,c,d,e,h,l,m,a etc 21 00 00 (ld hl,0) and a whole bunch of others. Working for IBM in the UK I wrote DOS device drivers for various Production line control cards. and a huge amount of assembly code. Your video took me back more than a few years!
this takes me way back.. I learned 68k assembly language to a good standard using a machine code monitors back in the day, I found the motorola cpu is a real joy to work with compared to the 6510 from the c64, there was no internet to speak of back then, interaction with others was done via voice over the phone or in a message base on a BBS, back then I ran a 3 node BBS which contained amongst other things a pretty active coding conference, it was the Seka assembler, that I used for a few years before DevPac came out.. comparing Seka to DevPac is like comparing the original vi to nano, but it was using Seka where I leaned concepts such as self modifying code and can remember how blown away I was at the time when I was able to see the changes while stepping through the code as it executed... good times fond memories
Found you Dave!! Thanks for Sharing! 47yo here, I tried to code as ä teen.... Star Trek game in Basic.. it had an error that I never found... I want to go back and try again! Thanks again for sharing your history & example in ASM coding. You really inspire me! I've been in the military for the past 26yrs, and was isolated. Now retired, out in the wild, ready to pursue my passions!
I Purchased a copy of MASM back in the early 80's, when software still came with BOUND MANUALS. I'll never forget just how much fun it was learning not only how to program in that language, but finally understanding just how Pascal, BASIC and C could be linked to your assembly language functions, and how the different call mechanisms worked, parameter passing, etc. I think my time programming in assembler was some of the most important in my programming career. I highly recommend it to anyone interested in how computers actually WORK, rather than how to make cool programs! Being 56 now, those days are far behind me, but I still cherish them! What an adventure it was :-}
it's rare to see such quality content thisese days, and it's even more awesome he speaks about things we today think of as the dark magic of compilers and frameworks and dont care about. keep this awesome content coming
I remember a pretty "big" collection of assembly widgets that didn't do much but were very amusing. The zip was found on most software repositories and it was out there to show what you could do with some seriously small bits of code. This was right before the big software bloat era.
I absolutely love these videos. I know there's an infinitesimally small chance that what I learned from this video will be used directly, but its still great knowledge. Learning low level information on how to interact with the native APIs is something you don't see very often, and I'm enjoying it a ton. I will admit, these videos strike a perfect balance between description and achieving an outcome, while I don't always understand perfectly whats going on, I understand enough of it to make sense of what I don't and you reach the goal in 1 video! That's impressive. Anyways, see you next time!
Just found this channel. I have to say this now in my top 5 favorite channels to view. I see a flight full of downloaded Dave's videos. Well done sir. Glad to see we old nerds are still makin' it happen. This is also a great stroll down memory lane to coding in the 80's. Cheers
I know what you mean. Having coded in ASM half of my life and experiencing the freedom, performance and lack of restrictions, after several minutes of of developing a web frontend I start swearing, cursing profiously and pounding my fist on the keyboard. Just yesterday, I became livid when I was writing a simple HTML5 upload widget, when it turned out that it is possible to select files or folders and upload them ...but it is NOT POSSIBLE to select BOTH files and folders and upload them. Who makes this shit up!
same. i'm still at university so i have no job yet but that really makes me think if IT it the thing for me. dont get me wrong i dont want to do anything else... but man... my brain isnt smart enough and its a shame
When I was in high school in the early 90s, one of my friends was writing programs in assembly. I thought I was nerdy until he started doing this. LOL. He would have gone far in life if he hadn't self deleted 2 days before graduation. He was a good friend and I still think about him to this day 30 years later.
Hello Dave, I thought I 'd better pay my dues and thank you for your generous offerings. I am an old electronics enthusiast from back in the thermionics days. My first computer was a CoCo64. I quickly discovered that Basic did not get me very far so Assembler was the answer. I loved it. I have not programmed since about 1996 and that was on the 486. I am really pleased to have discovered your clips and am inclined to dust off the old assembler again and see where it can take me in this jungle of languages. Thanks again.
I love you videos Dave. I was born in 2001 and I've always been interested in computers and how they work, but so much of how computers really work is abstracted away and hidden from us now a days. I think this leaves my generation of software developers with a more shallow understanding of what we're actually doing. Creating a windows application in assembly that draws a window was something I didn't think was possible but have always been curious about. This video has scratched an itch I've had for an extremely long time. Thank you!
I must say I really love seeing you use GNU nano! So many people tout the usefulness of editors like Vi/Vim etc but to be honest, sometimes the simplest of tools are the best!
Assembly was still part of my apprenticeship in 2005, and we weren't allowed to progress to C until we were reasonably adept at writing simple programs for the Z80 and C51. Unfortunately, I never got to use ASM again. This Video might change that :)
I did computer science at 17 and we spent a couple of months doing hand written binary arithmetic, not sure I ever used it, but gave me an appreciation of what's actually happening
Watching you program brought back memories of banging away at my keyboard all night long coding ASM for the 6502 and 8088. The late 70's - 80's were such an amazing time to be obsessed with computers, every day brought something new and wonderful to learn and play around with :-)
I love assembly . Started back in 1996 for 8-bit 6502 but never had time to go to the x86. Now im catching up. Cake work.... What I love the most is - SPEEEED, full hardver control, SMALL and apps. John from Serbia
It's a recommended practice in the x86 programming manuals from Intel and AMD: the register should be zero-initialised through the XOR operation with itself, rather than moving a zero into the register.
@@ruperttoncic9926 Yup, optimisation is a really powerful practice that's often overlooked these days. 8088 Corruption and 8088 Domination are enough proof of this.
@@shalinpather4198Z80 was the way forward! Back in the day... Wrote half of Space Invaders in less than 2K - I say half as I never had the time to finish it!
I did my Master's in computer science, graduating in 2020, and I had to do some pretty extensive assembly language programming for both of the computer architecture classes I had to take. The plot twist, though: neither of them was x86 assembly. One was a toy processor that only exists as a virtual machine, and the other was RISC V. It was more to understand how CPUs work and what your C (or whatever) code ultimately becomes, rather than because we were really expected to program assembly in the real world.
I also wrote a great deal of assembly and C for x86 including real-time schedulers (pseudo OS) for several systems. I also had to do some Z80 patching where we jumped to the end, patched in some instructions, and jumped back. Watching you do this was like stepping back in time. I enjoyed it immensely.
It is actually scary to see this video and think "oh, looks like he is just speeding it up a bit." But then you look at the webcam and realize he is really typing this fast. This man would dominate typeracer
13:42 Based on the speed of the video here it looks like most of the video is actually sped up a bit but it’s all no less impressive and this video and channel are awesome.
I too think that it's sped up. The audio filter gives the keyboard an incredibly cheap sound. Dave is most probably a "real kayboard" user. No cheap membrane KBs, but a mechanical ones, or at least one with high-end membrane switches. Still impressive, tho.
@@achtsekundenfurz7876 It's real time. If you look at the RGB lighting in the background and compare it's speed during typing with Dave's explanations the light motion is the same. Snappy digit man.
@@achtsekundenfurz7876 It is sped up. I love Dave's videos, and he is brilliant and quick I'm certain, but the typing is in fact too fast to be realistic if you look at it. Besides the proof is at 16:56 for anyone who doubts this. At 17:03 it resumes warp drive. He probably put that in there to see if anyone would catch it! I give the guy full props. I'll bet he was good with practical jokes around the office in his day. His videos are great!
Thanks Dave, another great video. I spent some of my early career developing in IBM 360/370 Assembly so it was very interesting for me to see the comparison.
I never managed to write 360 assembler code. The only reference source available to me (the IBM manual) carefully avoided any reference to I/O. However it did let me figure out a bit of what had happened in a core dump.
Two victories for you today Dave, that's the smallest windows app I've ever seen and the fastest I've ever hit Like and Subscribe. Congrats from an old C programmer who was also forged in the glorious and brutal 80s. :)
As a former developer who has been a hairdresser for the past 19 years, your videos have helped inspire me to re-learn how to code just for fun. Your content is very much appreciated by me!
I remember when we were writing some simple assembly programs and for some reason we were getting segfaults. We'd do everything according to the lab steps but when the program reached printf call, it'd just crash. We noticed if we just decide to push something else onto the stack it'd work, and if we pushed 1 more it wouldn't work, and 1 more push and it would work again. At some point I googled the instruction the program was segfaulting on and saw something about "stack alignment" and put two and two together and realized what was going on. Anyway, professor did not anticipate that the stack alignment would become an issue. There were some instructions inside that required 16 byte alignment, and with our 3 pushes to stack, we were just 1 quadword short of that. Perhaps in older systems the implementation was different.
Its quite funny what you actually remember. We are of a similar age and I wrote assembly language for the Amstrad CPC and Acorn computers. I still remember that calling &BB5A prints the character who's code is in the accumulator BUT I can't remember what I had for breakfast .........
Call 0a7fH Prints the character code in the accumulator on the Trs-80 Models I, II, III & IV. Maybe their color computer as well but that one I never used.
I'm glad I'm not the only one that hand-wrote assembly. I started learning Z80 assembler at the age of 11 on an Amstrad CPC and couldn't afford an assembler so ended up writing all my code in assembly and assembling it to machine code by hand and poking it in to memory from a BASIC program. Later, when I got an old 8088 based PC I wrote a Z80 cross-compiler for it in Pascal as a computer studies project. Happy, happy days!
I just want to say how happy I am that I stumbled onto Dave's Garage. His friendly cool persona is a breath of fresh air from a lot of other over-the-top YT personalities. I just like to listen to his videos while I'm working on coding. It's like having a good friend in the room at all times. Thanks for everything you do, Dave, I appreciate your content more than you will ever know. Keep up the good work!
Once upon a time there was a company (I believe) called 'Base Two' or maybe 'Phase Two' (I still have the disks around here somewhere). They produced an enormous library of x86 assembly macros which were really amazing, wide ranging, and simple to integrate into your own code. They were so well laid out that it actually helped with code design. I really miss coding with those. Sigh. Made x86 assembly coding fun instead of a slog.
And they went out of business. The end. Well, yeah, I agree, though. A well thought out assembly library is a great tool. You also have a point about the slog. "The slog" has been created, in my opinion, by two effects: everything that is server centric requires an incredible amount of plumbing over leaky pipes (many of which contain mostly sewage and deliberately toxic substances) and everybody wants to log the movements of the little toes of the user because they are worth a billion dollars (or so the advertising industry claims). So the same business process that once could be done with 16k of assembly on an eight bit CPU now requires a GByte of frontend, middleware and backend code. Use OOP in addition and you are up to 10GBytes. :-)
That was amazing. Thank you for the trip back in time. I cut my teeth on machine and assembler coding 6502's and 8085's. There are probably some of those still running traffic lights in smaller locals around the nation. I think you've forgotten more about coding then I ever learned. Respect!
Lol that background music is wonderful! Not even being sarcastic, it’s like “just relax as we do something that will cause most people nothing but misery and pain”
Same here - I used Turbo Pascal inline assembly to access and display file/directory info., and perform other low-level functions. Borland was at its peak during those times.
"Turbo Pascal" - I haven't heard that spoken in years! I loved my Turbo Pascal. Only generated ___.com files that were minimum 10 K long, but the Integrated Development Environment was so clean. Easy to run and and then compile.
@@christopherknee5756 In college all I needed to write code was contained on a 3-1/2 inch floppy 💾 disk, which contained the entire Turbo Pascal Compiler and my source code/output files. No need for a Terabyte hard drive back in those simpler times! Also used the inline assembly feature to interact with the DOS-based file system and perform tricks like displaying the time in the program's execution.
Dave needs to make a video of himself getting the assembly dump from a complete Ubuntu Linux distro on different architectures. I'd love to see what the filesystem looks like in various assembly architectures
What I love about this channel is Dave's candidness about some of his inter-personal skills being somewhat sub-par and how he has managed to still succeed while some of us are repeatedly told it'll hold us back. I'm prone to making badly-timed interjections that (although honourable and honest) usually end up being about as welcome as a fart in an elevator to those who haven't taken a moment to get to know me. I'm also a big fan of his obvious thirst for knowledge when it comes to anything engineering based - my grandfather was a classic American car restorer here in the UK in his retirement and as a kid I was mesmerised with his metal-working skills. I am addicted to Dave's anecdotes :D
I just bought a mug and I don't even drink coffee anymore (too much in my lifetime, I'm allergic to caffeine now, developer life ain't easy!). I just love the fact that Dave isn't in it for money but "just fame", and is just providing merch to give the profits away. That's reason enough to buy it. I hope there'll be more goodies.
The most edifying aspect of this exercise is the way Dave shows you how to diligently document your source code: one line at a time, code on the left, comments on the right. C++ programmers, take heed, you may not have a convenient comment tab to neatly line up your comments in a column, but you can still use the right side of your text page to document your code.
I'm not a Coder, although I do recall entering machine code into a Motorola microcontroller half a century ago. What fascinates me is how steeped Dave is in Microsoftness. He uses 'dll' as if it were the very bread of life. He provides an insight into the MS religion, the opaqueness, the special handshakes and implicit nods. How somehow, we should all know - 'this is the way'.
Dave, Just wanted to say, thank you for donating to Autism research; my brother and several close friends of mine are autistic and i cannot thank you enough. Also, thanks for the entertainment!
Watching Dave is like listening to the jazz music in the background... I kinda know what's going on, it's all happening so fast, it's all so intricate, and I'm enjoying myself
What a refreshing breath of old air. :) Seriously though, fantastic presentation for all of us older folks who were still kids when this stuff was the common way of the code.
If a computer is doing it it's doing it in machine code which translates directly into Assembly language so yes, you can call into DLLs from Assembly language. The actual code for doing it is in the _include_ files listed at the beginning. They're human-readable so you can go see what's going on if you're interested.

I like how calm and collected he is. Complete in tune with his emotions. I assume he had done several rehearsals but it still amazes me how he codes straight forward.
I took a class in x86 assembly when I was working on my Comp Sci field of study certificate, and I actually enjoyed it quite a bit. I mentioned this on the day of the final while we were waiting for the instructor, and everyone looked at me as if I should have been in a strait jacket and a padded room. 😅
ok. That was ultra cool. Brings back so many memories. I used to love that coding in assembler meant any bug was my own dang fault, and not some issue with the libraries, etc...
Having toggled instructions into the PDP-11 and a few years later, dealing with punch cards and magnetic tapes on the IBM 360 ~1972, I am always awestruck by the genius of comp sci engineers who developed the first “GUI” (wish I had thought of that! Best we had was the TTY output). Dave if it would be at all possible, could you do an even deeper dive into the workings of the libraries especially GDI32.lib which you had to include in this tiny window project? Between your channel and Ben Eater’s this is coding/hardware beautyfullness! Thanks for your effort!
I'm of that certain age, but 6502 is not burnt into my synapses. Why? Because I used Motorola 6802, similar but with some important differences (one of them made me waste two weeks trying to find a bug in the first and only program I wrote for 6502... that bug would not be such in 6802).
@@Jeff-xy7fv The owner's manual for that thing is legendary. Every bit, nibble and byte accounted for in exquisite detail. The alternate characters on the keyboard, the ability to obfuscate BASIC code by changing font colors to match the background or place special backspace characters in the code. I still have mine, including my log book containing the tape counters as to where my apps are. The C64 was an incredible computer and still to this day my favorite computer EVER. Only a Raspberry Pi is as much fun to own and use.
hi, I like the circuits related topic and how to turn them into assembly. I think intel give too much choices in the x86. I have to much way to finish the same task, but I like a more compact size assembly code with hardware transactions enabled, but now I'm doing other things. watching u code is also a good thing.😎
Hey Dave! I know you don't do much of this but, I'd love for you to do tutorials about cool old stuff like this for beginners. Like a beginner's series on x86 assembly language with an end goal of being able to make windows apps with it. Or teaching c++ with end goal of making win32 api programs like your other video
I wish I took this path back in the 80's. Computer programming has always intrigued me. Dave is a classic! He explains it so well. I love his humor. Congrats on your achievements sir!
Explains it so well?? I had to program the Windows API at the assembly level for a couple of years (for a compiler I was designing). I got it working somehow, but never understood most of the API abstractions. This does not help either, it just pore salt in the wound for me.
With this channel I found the gold mine. For other programming videos I've created playlist "Prog" but for this I've created a separate playlist called "Real Engineering Prog".

The flex starts at the video title where he wrote "assembly"
Even in fast mode, that clicky keyboard is a very distinct sound.. I would bet it's an original IBM model M or a close cousin.. the sound still makes me jealous and wish I still had my original AT keyboard.
@@SteveJones172pilot I do have a model M and trust me it's not that one. Sounds like modern tactile switches.

@@DavesGarage Thank you, because you made my Heretic gaming days, epic.
Haha, ask me, I surely needn't tell - from 8-bit pixel graphics in 320x200 to software-rasterized vector line graphics to the first textured 3D after gouraud (looking at you, TIE Fighter) - to now graphics cards that do not only do global illumination in real-time but can also do raytracing, in real-time and hardware!

Getting MS-DOS 'for free' yet buying DR-DOS in the States (I live in Europe) was an adventure of its own. "Programmers paradise" was the nearest shop for me.... At 5000 miles distance.
Even for a modern C++ programmer, this gives a lot of insight to how programming was in the early 90s/late 80s. The commenting work is also very good! Learned some stuff I never knew about Windows.
I don't really get what he says though. Sounds like he's swallowing half of most words.
And he is so C-centric (and also windows centric) that it hurts.
@@herrbonk3635 well... why would he be talking about Mac / Linux in a video about Windows?
@@martysh1226 Well, Linux is even more C-centric. The old Windows API structures were originally defined in Pascal in the mid 1980s, largely taken from Xerox (very much like the first Lisa/Mac systems that were also written in Pascal). That's why we still use "PASCAL" calls on the ABI-level when writing Win32 code in C/C++ (although renamed STDCALL today, iirc).
However, I did this in the 1990s without thinking much in either C or Pascal. I though in terms of assembly plain and simple.

You're a machine Dave. I've coding for 15 years and I can't still code that fast... impressive.
Indeed, he is a machine. For a while I assumed he sped up the video, (there were some suspicious camera cuts, such as 22:30) but nope, he really does type code that fast. It looks impossible. I had to LOL several times. But he could have sped up his typing by 2% if he learned the keystroke for "delete previous word" rather than hitting the backspace character multiple times in a row.
I don't know but it looks pre recorded coding rather than live coding. The text cursor stops as he turns around to speak and also the blinking speed of that text cursor is fast (Like 2x - 3x or so). Also when he exit the nano editor, the directory is changed. I might be wrong on all these but yeah I noticed that.
@@cyberwaves I hear ya. Maybe someone with OCD can slow down the video and analyze the keystrokes, comparing them with what actually appears on screen.
@@TheNameOfJesus Did you really just use OCD as a synonym for "doing something detailed"? See, THIS is why people get annoyed at people just throwing around legitimately destructive mental health issues like OCD and lifelong, disabling neurodevelopmental diagnoses for fun.

I emailed Dave the other day about the Windows Message Pump, and he replied within 2 hours. This channel is awesome!
Watching Dave livecode is as relaxing as watching Bob Ross paint.

His speech is the same to me, a fast weak noise. His phrases are hard to decipher for an outsider.
I also grew up in the '80s but I was in Louisiana. As you might expect, things were not great for a computer nerd during those days. I had my Commodore 64, banging out BASIC scripts, but I lacked resources or a mentor that could take me to the next level. My guidance counselors, who didn't understand computers, didn't encourage me to go down that path for a career. I literally thought you could be a scientist or work in a store. Retail is what I ended up doing for 10 years, though I was always building my own PCs. I finally broke into the IT support business and never looked back. Still can't code very well though. I wish I had focused on it more when I was young. So if you are a young person, or a parent of one, and your child shows an inclination to learn programming, by all means support them and try to encourage them to learn as much as they can.
Argentina and TRS-80 (Models I and III) for me; not mine, for some mysterious reason they allowed me to use them in a retail shop. Luckily there was some documentation for the API calls for the TRS-DOS, and it had a debugger that allowed you to to step-by-step and basic disassembling. With that and a book on Z80 I ended up reverse-engineering the operating system when I was 14 years old. Good times.
It's never too late
I learned assymbly recently and still learning.

I love to watch a master at work, machinist, electritians, carpet layers, roofers ect. Most of this is so far over my head. the peak of my programing was a basic program to calculate the length of a bicycle spoke, took me a week. I got clear through this and hold you in awe!
Started a computer science course in 1966. At BU it was simply called programming, we used Dartmouth Timeshare BASIC. In my career the most sophisticated language I ever used was Pascal, GUI programming scared me. Recently, after retirement, I bought a few Raspberry PIs and learned Python. When I was at Digital Equipment Corp I taught their machine code and assembly language. All this has no value unless I want to start a UA-cam channel.

I had to do two double-takes when I read the title, first thinking something must be wrong, as I was sure I’d seen this video a week ago, and then confirming I actually read the title correctly.
I thought your previous video was unbelievable enough, I was shocked you could go so low in windows, having to manage so much yourself, so to turn around and do the same things in ASM, I’m speechless. It’s truly amazing to see an entire program written this way, it feels so alien to anything I’ve seen before (and in a fifth the time it takes me to get a 6502 spitting out data through a serial connector no less)!
You never fail to amaze, best of all is that you explain things as you go in a way that even I can follow along with, that’s saying something.

Great channel Dave...don’t stop.
Oh the memories you brought back to this 73 yr old nerd. Started with assembler cutting my eye teeth with MASM. Enjoy your channel immensely Thanks Dave for another walk down memory lane.
You make that look so easy, the flood of memories from my windows 2.X days reminded me that nothing was easy back then. You had to really work for performance. Great demonstration of an ancient art, definitely a "Bob Ross" moment.
Im doing an education as Application Developer specialized on application development and im always impressed when someone writes in Assembly or still uses "old" languages. Keep it up!
There's nothing more satisfying than building something from scratch and seeing it work! Thanks Dave!
Loved this! Brought back memories of my machine language work in 8080 in the mid-'70s. I couldn't afford an "OS" after building the IMSAI, so a friend gave me a copy of his Altair basic. I wrote a machine language program to search for the input instructions, as the IMSAI could be loaded from the front panel, find the input/output commands, and then I wrote a jump to my input/output to my devices (Altair basic was loaded with my homemade "Tarbell" tape interface). When I finally acquired an 'assembler' for the 8080 I thought I had died and gone to heaven! The best program I ever wrote on the IMSAI/8080 was a "BAUDOT to ASCII" converter so I could use ASCII on ham radio RTTY. (Today ASCII is ok on ham radio, but not back then! ) - And to think we had 1K boards back then plugged into our S-100 bus! Fun Stuff! BTW< who else do you know who started their career with Western Union as a teletype tech and finished (retired) with Cisco Systems !!
How I wanted an altair in 1975. Looked like those movie computers till I discovered a "computer store" by accident. The owner convinced me to get a SWTPC6800 with two buttons ON-OFF / RESET instead of flipping switches just to read a keyboard, to type code to read a cassette tape program etc. The swtpc6800 used a "BIOS" called MIKBUG which had code to read a serial keyboard, display to a serial monitor, load and save a program from and to a serial cassette tape machine, enter an address and type machine code in hex. I thought "who needs blisters on their fingers" suffered by many an altair user.
I have been a programming since this guy the 1970s ( I was maybe 14 when I first wrote some code,) and watching this guy bang out assembler code like he was typing an email is humbling :)
I started with the 8080a - in machine language and can still remember most of the codes! 40-7F were reg moves ,b,c,d,e,h,l,m,a etc 21 00 00 (ld hl,0) and a whole bunch of others. Working for IBM in the UK I wrote DOS device drivers for various Production line control cards. and a huge amount of assembly code. Your video took me back more than a few years!
Assembly is still the language I love. I am now at a point I am trying to learn higher level language. I use my programs to run motors in a factory.
also for me ❤️
this takes me way back.. I learned 68k assembly language to a good standard using a machine code monitors back in the day, I found the motorola cpu is a real joy to work with compared to the 6510 from the c64, there was no internet to speak of back then, interaction with others was done via voice over the phone or in a message base on a BBS, back then I ran a 3 node BBS which contained amongst other things a pretty active coding conference, it was the Seka assembler, that I used for a few years before DevPac came out.. comparing Seka to DevPac is like comparing the original vi to nano, but it was using Seka where I leaned concepts such as self modifying code and can remember how blown away I was at the time when I was able to see the changes while stepping through the code as it executed... good times fond memories
keeping those algorithms happy...
Found you Dave!! Thanks for Sharing! 47yo here, I tried to code as ä teen.... Star Trek game in Basic.. it had an error that I never found... I want to go back and try again!
Thanks again for sharing your history & example in ASM coding.
You really inspire me!
I've been in the military for the past 26yrs, and was isolated. Now retired, out in the wild, ready to pursue my passions!
I Purchased a copy of MASM back in the early 80's, when software still came with BOUND MANUALS. I'll never forget just how much fun it was learning not only how to program in that language, but finally understanding just how Pascal, BASIC and C could be linked to your assembly language functions, and how the different call mechanisms worked, parameter passing, etc. I think my time programming in assembler was some of the most important in my programming career. I highly recommend it to anyone interested in how computers actually WORK, rather than how to make cool programs!
Being 56 now, those days are far behind me, but I still cherish them! What an adventure it was :-}
it's rare to see such quality content thisese days, and it's even more awesome he speaks about things we today think of as the dark magic of compilers and frameworks and dont care about. keep this awesome content coming
I remember a pretty "big" collection of assembly widgets that didn't do much but were very amusing. The zip was found on most software repositories and it was out there to show what you could do with some seriously small bits of code. This was right before the big software bloat era.
I absolutely love these videos. I know there's an infinitesimally small chance that what I learned from this video will be used directly, but its still great knowledge. Learning low level information on how to interact with the native APIs is something you don't see very often, and I'm enjoying it a ton.
I will admit, these videos strike a perfect balance between description and achieving an outcome, while I don't always understand perfectly whats going on, I understand enough of it to make sense of what I don't and you reach the goal in 1 video! That's impressive.

Hello Dave, I thought I 'd better pay my dues and thank you for your generous offerings. I am an old electronics enthusiast from back in the thermionics days. My first computer was a CoCo64. I quickly discovered that Basic did not get me very far so Assembler was the answer. I loved it. I have not programmed since about 1996 and that was on the 486. I am really pleased to have discovered your clips and am inclined to dust off the old assembler again and see where it can take me in this jungle of languages. Thanks again.
I love you videos Dave. I was born in 2001 and I've always been interested in computers and how they work, but so much of how computers really work is abstracted away and hidden from us now a days. I think this leaves my generation of software developers with a more shallow understanding of what we're actually doing.
Creating a windows application in assembly that draws a window was something I didn't think was possible but have always been curious about. This video has scratched an itch I've had for an extremely long time. Thank you!
I must say I really love seeing you use GNU nano! So many people tout the usefulness of editors like Vi/Vim etc but to be honest, sometimes the simplest of tools are the best!

@@GothAlice I agree.
Assembly was still part of my apprenticeship in 2005, and we weren't allowed to progress to C until we were reasonably adept at writing simple programs for the Z80 and C51. Unfortunately, I never got to use ASM again. This Video might change that :)
I did computer science at 17 and we spent a couple of months doing hand written binary arithmetic, not sure I ever used it, but gave me an appreciation of what's actually happening
I used ASM on 8048, 8051 and then PIC micros for decades before learning C.

Watching you program brought back memories of banging away at my keyboard all night long coding ASM for the 6502 and 8088. The late 70's - 80's were such an amazing time to be obsessed with computers, every day brought something new and wonderful to learn and play around with :-)

I love Dave's observation that xor-ing out the contents of the register is "a tad more efficient" than writing zero to it!
It's a recommended practice in the x86 programming manuals from Intel and AMD: the register should be zero-initialised through the XOR operation with itself, rather than moving a zero into the register.
This cuts out the memory fetch cycle(s) on all processors. Every little helps...

I did my Master's in computer science, graduating in 2020, and I had to do some pretty extensive assembly language programming for both of the computer architecture classes I had to take.
The plot twist, though: neither of them was x86 assembly. One was a toy processor that only exists as a virtual machine, and the other was RISC V.
It was more to understand how CPUs work and what your C (or whatever) code ultimately becomes, rather than because we were really expected to program assembly in the real world.
I had no clue you wrote task manager, you’re now officially my hero
I also wrote a great deal of assembly and C for x86 including real-time schedulers (pseudo OS) for several systems. I also had to do some Z80 patching where we jumped to the end, patched in some instructions, and jumped back. Watching you do this was like stepping back in time. I enjoyed it immensely.
Thirty years later, I learn how YOU really did it. Thanks!
It is actually scary to see this video and think "oh, looks like he is just speeding it up a bit." But then you look at the webcam and realize he is really typing this fast.

It’s fast but it’s hardly uncommon.
13:42 Based on the speed of the video here it looks like most of the video is actually sped up a bit but it’s all no less impressive and this video and channel are awesome.
I too think that it's sped up. The audio filter gives the keyboard an incredibly cheap sound. Dave is most probably a "real kayboard" user. No cheap membrane KBs, but a mechanical ones, or at least one with high-end membrane switches.

As a former developer who has been a hairdresser for the past 19 years, your videos have helped inspire me to re-learn how to code just for fun. Your content is very much appreciated by me!
I remember when we were writing some simple assembly programs and for some reason we were getting segfaults. We'd do everything according to the lab steps but when the program reached printf call, it'd just crash.
We noticed if we just decide to push something else onto the stack it'd work, and if we pushed 1 more it wouldn't work, and 1 more push and it would work again. At some point I googled the instruction the program was segfaulting on and saw something about "stack alignment" and put two and two together and realized what was going on.
Anyway, professor did not anticipate that the stack alignment would become an issue. There were some instructions inside that required 16 byte alignment, and with our 3 pushes to stack, we were just 1 quadword short of that. Perhaps in older systems the implementation was different.
I still don't know whats happening but i can't stop watching
Its quite funny what you actually remember. We are of a similar age and I wrote assembly language for the Amstrad CPC and Acorn computers. I still remember that calling &BB5A prints the character who's code is in the accumulator BUT I can't remember what I had for breakfast .........
Call 0a7fH
Prints the character code in the accumulator on the Trs-80 Models I, II, III & IV.
Maybe their color computer as well but that one I never used.
@@jeremiahlyleseditor437 The problem with modern computers is that you can't know it all whereas with all machines you could know most of it
I'm glad I'm not the only one that hand-wrote assembly. I started learning Z80 assembler at the age of 11 on an Amstrad CPC and couldn't afford an assembler so ended up writing all my code in assembly and assembling it to machine code by hand and poking it in to memory from a BASIC program. Later, when I got an old 8088 based PC I wrote a Z80 cross-compiler for it in Pascal as a computer studies project. Happy, happy days!

Once upon a time there was a company (I believe) called 'Base Two' or maybe 'Phase Two' (I still have the disks around here somewhere). They produced an enormous library of x86 assembly macros which were really amazing, wide ranging, and simple to integrate into your own code. They were so well laid out that it actually helped with code design. I really miss coding with those. Sigh. Made x86 assembly coding fun instead of a slog.
And they went out of business. The end. Well, yeah, I agree, though. A well thought out assembly library is a great tool. You also have a point about the slog. "The slog" has been created, in my opinion, by two effects: everything that is server centric requires an incredible amount of plumbing over leaky pipes (many of which contain mostly sewage and deliberately toxic substances) and everybody wants to log the movements of the little toes of the user because they are worth a billion dollars (or so the advertising industry claims). So the same business process that once could be done with 16k of assembly on an eight bit CPU now requires a GByte of frontend, middleware and backend code. Use OOP in addition and you are up to 10GBytes. :-)
I thought the video is sped up when he was coding. But no, it is in real-time. OMG :^)
That was amazing. Thank you for the trip back in time. I cut my teeth on machine and assembler coding 6502's and 8085's. There are probably some of those still running traffic lights in smaller locals around the nation.

Boy if you saw my messy bloated code - I love watching an expert in their craft. Thanks!
Lol that background music is wonderful! Not even being sarcastic, it’s like “just relax as we do something that will cause most people nothing but misery and pain”
Yep - I don't normally listen to music while I code because I get easily distracted by most kinds of music, but I'd totally code to that.
I used to love that Turbo Pascal allowed inline assembly - used it when writing a texture mapping routine back in the day.
And that you can do 32 bit asm inline by prefixing each instruction with db 066h. Joys!!
Same here - I used Turbo Pascal inline assembly to access and display file/directory info., and perform other low-level functions. Borland was at its peak during those times.
"Turbo Pascal" - I haven't heard that spoken in years! I loved my Turbo Pascal. Only generated ___.com files that were minimum 10 K long, but the Integrated Development Environment was so clean. Easy to run and and then compile.
@@christopherknee5756 In college all I needed to write code was contained on a 3-1/2 inch floppy 💾 disk, which contained the entire Turbo Pascal Compiler and my source code/output files. No need for a Terabyte hard drive back in those simpler times! Also used the inline assembly feature to interact with the DOS-based file system and perform tricks like displaying the time in the program's execution.
Dave needs to make an episode of himself porting reversi from windows 1.0 to windows 11 just so we all can see his thought process in such a task
Dave needs to make a video of himself getting the assembly dump from a complete Ubuntu Linux distro on different architectures. I'd love to see what the filesystem looks like in various assembly architectures
What I love about this channel is Dave's candidness about some of his inter-personal skills being somewhat sub-par and how he has managed to still succeed while some of us are repeatedly told it'll hold us back. I'm prone to making badly-timed interjections that (although honourable and honest) usually end up being about as welcome as a fart in an elevator to those who haven't taken a moment to get to know me.
I'm also a big fan of his obvious thirst for knowledge when it comes to anything engineering based - my grandfather was a classic American car restorer here in the UK in his retirement and as a kid I was mesmerised with his metal-working skills. I am addicted to Dave's anecdotes :D

I just love the fact that Dave isn't in it for money but "just fame", and is just providing merch to give the profits away. That's reason enough to buy it. I hope there'll be more goodies.
The most edifying aspect of this exercise is the way Dave shows you how to diligently document your source code: one line at a time, code on the left, comments on the right. C++ programmers, take heed, you may not have a convenient comment tab to neatly line up your comments in a column, but you can still use the right side of your text page to document your code.
I'm not a Coder, although I do recall entering machine code into a Motorola microcontroller half a century ago. What fascinates me is how steeped Dave is in Microsoftness. He uses 'dll' as if it were the very bread of life. He provides an insight into the MS religion, the opaqueness, the special handshakes and implicit nods. How somehow, we should all know - 'this is the way'.
Dave,
Just wanted to say, thank you for donating to Autism research; my brother and several close friends of mine are autistic and i cannot thank you enough.
Also, thanks for the entertainment!
Thank you for inventing the scientific method for improving pork products.
Watching Dave is like listening to the jazz music in the background... I kinda know what's going on, it's all happening so fast, it's all so intricate, and I'm enjoying myself
What a refreshing breath of old air. :)
Seriously though, fantastic presentation for all of us older folks who were still kids when this stuff was the common way of the code.
That is your actual typing speed? It's amazing. I didn't knew you could load libraries from assembly. Thank you for your very instructive videos ;)
I'm pretty sure it's sped up
If a computer is doing it it's doing it in machine code which translates directly into Assembly language so yes, you can call into DLLs from Assembly language.
The actual code for doing it is in the _include_ files listed at the beginning. They're human-readable so you can go see what's going on if you're interested.
28:38 My very first thought was "I need to head over to GRC and see what Steve's app sizes are."
I LOL'ed at the SG quip, and I was beginning to worry I might be the only one to get it having scrolled this far down in the comments
@@starlite528 I haven't even watched the video, saw the title and said hmmm I haven't checked out GRC in prob a decade or longer.
Me: I'm gonna learn Vim because I hear I can be faster and more efficient than if I use Nano
Dave: Watch me do circles around Vim users with my Nano coding
Wow! A double bonus. Finding this channel of Dave's and the comment posted by Steve Gibson. Thank you both for your insightful commentary and incisive programming. Sirs, I salute you!
I worked with MASM assembly back in 2013. I got really good at it too, but I don't remember a single command today. Dave, you're amazing.
Human words == assembly, Gobblygook == machine language. Great way to help anyone distinguish the difference and look smart to thier friends.
"are you sitting comfortably?"
*Corrects contortionist position slightly*
Suggestion for next video:
“Learn how to code like Dave”- aka “How I learned to stop worrying about dependencies and type at 300 bauds!”
Seriously, love the throwbacks to my own programming adolescence.
Thank you.
Still can't believe he types this fast!
I like how calm and collected he is. Complete in tune with his emotions. I assume he had done several rehearsals but it still amazes me how he codes straight forward.
@@antesmolcic4354 It's speed up
@@do0nv I don't think it's sped up. Watch 12:45, with an unbroken shot of him talking, coding, then talking.
I took a class in x86 assembly when I was working on my Comp Sci field of study certificate, and I actually enjoyed it quite a bit.
I mentioned this on the day of the final while we were waiting for the instructor, and everyone looked at me as if I should have been in a strait jacket and a padded room. 😅
ok. That was ultra cool. Brings back so many memories. I used to love that coding in assembler meant any bug was my own dang fault, and not some issue with the libraries, etc...
Having toggled instructions into the PDP-11 and a few years later, dealing with punch cards and magnetic tapes on the IBM 360 ~1972, I am always awestruck by the genius of comp sci engineers who developed the first “GUI” (wish I had thought of that! Best we had was the TTY output). Dave if it would be at all possible, could you do an even deeper dive into the workings of the libraries especially GDI32.lib which you had to include in this tiny window project? Between your channel and Ben Eater’s this is coding/hardware beautyfullness! Thanks for your effort!
As soon as I saw ‘A9’ instantly thought “LDA immediate mode” - if you’re of a certain age, 6502 is burnt into your synapses
...and by extension 6510, that $D021 address as well even if you don't speak ML/assembler.
Yep! It's burnt into mine. Has been since I was 12 years old and playing around with a C64.
I'm of that certain age, but 6502 is not burnt into my synapses. Why? Because I used Motorola 6802, similar but with some important differences (one of them made me waste two weeks trying to find a bug in the first and only program I wrote for 6502... that bug would not be such in 6802).
@@Jeff-xy7fv The owner's manual for that thing is legendary. Every bit, nibble and byte accounted for in exquisite detail. The alternate characters on the keyboard, the ability to obfuscate BASIC code by changing font colors to match the background or place special backspace characters in the code. I still have mine, including my log book containing the tape counters as to where my apps are. The C64 was an incredible computer and still to this day my favorite computer EVER. Only a Raspberry Pi is as much fun to own and use.
"'l'll shell out" Haven't heard anyone use that phrase is loooong time.
I honestly had no clue what it meant (other than "cough up the money") until he quit nano, and now I can guess at the meaning.
I love this, I was a spaggetti basic nerd back in the day and these videos bring back so many memories of life before mice
As a assembly language learner myself, hearing "no include files, no version files, or manifest, or other nonsense" I subscribed the next second.
I loved learning assembly in my CS courses. It’s great to see that you could program a Windows application using assembly even in the modern day
hi, I like the circuits related topic and how to turn them into assembly. I think intel give too much choices in the x86. I have to much way to finish the same task, but I like a more compact size assembly code with hardware transactions enabled, but now I'm doing other things. watching u code is also a good thing.😎
dave is a treasure to the programmers community
Hey Dave! I know you don't do much of this but, I'd love for you to do tutorials about cool old stuff like this for beginners. Like a beginner's series on x86 assembly language with an end goal of being able to make windows apps with it. Or teaching c++ with end goal of making win32 api programs like your other video
I wish I took this path back in the 80's. Computer programming has always intrigued me. Dave is a classic! He explains it so well. I love his humor. Congrats on your achievements sir!
Explains it so well?? I had to program the Windows API at the assembly level for a couple of years (for a compiler I was designing). I got it working somehow, but never understood most of the API abstractions. This does not help either, it just pore salt in the wound for me.
With this channel I found the gold mine. For other programming videos I've created playlist "Prog" but for this I've created a separate playlist called "Real Engineering Prog".
