type banana Dave Plummer is a cool and handsome dude. He will gladly send the first person to comment about this decoded text a rare Task Manager pin.

Dave is like that kind developer buddy you always wanted to have.

I see we are shouting out MattKC today. Time for Dave to work Lego Island?

At a job interview: "Can I see your portfolio?" *Pulls out a physical binder full of QR codes* I love this kind of content. Would love to see a game in there if you can fit it!

MattKC and Dave's Garage collab? Yes please!

BTW nice featuring both MattKC and 8-Bit Guy on the description =)

Very interesting topic and something MattKC also accomplished with a whole game of Snake on a QR code.

MattKC should do more technical videos, he manages to do it in a very charming way. His sunny australian disposition always lifts my mood.

You missed a golden opportunity to rick roll us all with that QR code at the beginning. :D

Thank you for crediting MattKC, his QR version of snake was hella impressive.

Came here by reference of a friend in Twitter, and I enjoyed the video showing Dave's effort for this, and also the previous video on Windows programming (it looks like I have a duty of watching some more videos!). Also was pretty awesome for me to be mentioned there :) Thank you! Not tried before writing a Windows assembler game, but I could give it a look ;)

I love watching these videos. I'm a relatively novice programmer. I can get things done but not nearly as elegant as you and I have very little experience with this low level coding. So its so confusing but mesmerizing to watch you code.

MattKC made a video on this, and it was a really fun video to watch. So fun in fact, that I've rewatched it multiple times. I'm so happy that you've made a video with the same topic!

"8-bit man" you meant 8-bit guy! Super interesting video!

I found Matt's video so interesting and I'm glad to see another person tackle it.

Dave! Camera distance is PERFECT. Thank you!

I like how you call The 8-Bit Guy as 8-Bit Man in the description lol

When I saw the ASM video I wanted to suggest looking at MattKC's video. Super happy to see it mentioned just a few days later. 😊

Always interesting! Always wanting to see more. Thanks for the video!

You have so much wisdom and experience, your videos are fun and interesting to watch. Love the channel!

That was awesome that you did a shout out for MattKC, I literally just came from watching his video on hacking minesweeper, and now I want to go try and figure out why minesweeper NT works on 9x and Windows 10 but not the XP version on 9x, perhaps an idea for another video? I love this, it feels like the MASM scene is coming alive again. :D

I love your channel! in answer to your question about interest in adding functionality, yes please do this. Thank you for all of these videos, even the Mech/product stuff, way cool!

bit of history about paper tape - the "paper" tape they used for bootstrapping was metal, very thin, very flexible metal - for longevity.

Today, just got more fun! Thanks Dave!

Damn Dave, so much great content recently.. love your stuff and dedication, keep it up!

Thanks for the SonicMouse shout-out, Dave! I didn't think you saw my email.

Love your videos Dave. I think I’d love to see a collab between you and barnacules chatting about each of your experiences at msft.

More QR code videos please! I found this really interesting

Use the space to turn on the lights, some Rube Goldberg level magic ^-^ Can’t get enough of these vids!! More pls

A call out to "Can you fit a whole game into a QR code?" by MattKC I must say I like seeing it in assembly language as MattKC didn't do that successfully.

What a fantastic experience it's been discovering your channel! I've been a distro-hopping Linux-at-home user since 2007 when I used a gifted-to-me Puppy live CD to download windows drivers for a newer Ethernet PCI NIC and thought, "whoah... It just works?" and have only recently discovered and enabled wsl for familiarity on corporate images at work. My only real "programming" these days is limited to the simple instructions and constraints of PLCs for work and python for data-collection... but I really very much enjoy your content: Great humor, great stories, great way to spend some free time. Thank you.

I watched MattKC's video shortly before I ever found your channel (thank you algorithm XD) and as soon as you said you knew how to write assembly during the assembly app video, I immediately hoped you would make a QR code app because you seemed to have a ton of knowhow on saving space

My best learning video for monday afternoon. Amazing!

That was an awesome video dude, can't believe how small that application is lol ; Assembly magic

Keep going! Love these vids!

UKposts on my phone decided to crash right after the phrase "now watch what happens when you run temp.exe". Perfect timing.

With your Schrödinger Cat comparison, you equated the QM effects of observation to code running. Very interesting description!

Really fun watching this guys videos, I learned some C back in the 80's but it was way overkill for what I was doing, and Perl and tcl / tk do anything I need to do as an average mook these days, but it's really fun to watch stuff done like a Chad.

Best channel on UKposts hands down!

3:45, I actually was calculating that ATM, thanks XD Love your videos, keep the ASM ones coming please :)

nice video, keep it up. I love every video you make.

This and Matt KC's work suddenly makes me want to pick up some programming again, maybe Assembly or something simpler.

Cool video . Learned a lot from it . Different field to me but you explained the science very effortlessly. Now I am curious about learning more. Subscribed

Absolutely Dave! It would be neat if you could fit two functional programs in a single QR code. I like the idea of a "two for one" deal.

Gotta love how you casually pull off the WSL and treat things like its belongs to Windows like any program.

Really enjoying your videos. Would like to see you include flutter (well, dart, I suppose) in the performance evaluation against other languages!

Heck yeah, you too watch MattKC!!

This was the first video that I was able to enjoy while sipping a tasty beverage from my official Dave's Garage mug. 😁👍 I need to actually spend some time writing code. I've learned how to read it, but I still don't really write anything besides adjustments to things that don't run correctly. (I have to increase my proficiency with the vocabulary, mostly, if viewed similarly to a non-programming language.) 🤔

Now that is a software challenge!

Very Cool Dave. Thank you.

My only experience of asm was using a pic 2 decades ago, but this was fascinating

OH PLEASE PLEASE GAMES IN QR CODES! YUSSSS! Dave, you're freaking awesome.

Great episode Dave.

Such a wholesome channel!

Wow! That's some impressive size! Now, I'm tempted to see how small I can write a simple Windows game! :D

Thank you for this. I like this kind of thing

More QR code videos! Super cool.

Keep it up, thanks for sharing the video :)

you are amazing, love the content

An interesting adaptation of this would be to support TOTP, using a QR Code for 2FA. What would make it even more useful is embedding the primary and secondary factors in the same QR code -- A password manager + 2FA TOTP in the same code, so then you have instant login without the hassle :-)

This is a new level.

Never occurred to me that this was possible, good to know!

Thanks for all your videos, I want to see this toic developed to it's maxiumum potetial.

Amazing, reminds me of an old saying, "what a tangled web we perceive when we first start to deceive" or something like that.

Maybe code in some minimal win32 printing functionality to make it replicate itself as a printed QR-code on startup :D Great video as always, Dave!

I am always impressed by small binaries, but my favorite has to be "elevated by Rgba & TBC", 4kiB total size for 3D and music.. Doesn't fit in a QR code but it's super impressive.

this channel is so entertaining :-D

Most underrated channel on UKposts!

Dave, what do you think of 'actually portable executable' by Justine Tunney? Seems like total black magic, maybe a nice subject for an episode?

Do it! Do more! Love it!

YES 100%. This is the coolest thing I've ever seen, definitely pursue the functional app, if its a game or otherwise. I've always had a strange fascination with storing digital data on inappropriate physical media, i.e. text in a bitmap, printed, or picture in audio etc... I have to say executable in a QR code takes the cake. My ex suffered from paranoid delusions, and I confidently informed her that it was impossible for a QR code to hack her devices, on the basis they couldn't store enough data for a functional executable... time to retract that position i guess...

Peanut butter and jam pre-mixed? They don't sell that here. You've been out of Canada for a while Dave. Great video, by the way. Love them all.

Those who ever deal with IBM mainframes will have been familiar with a programme called IEFBR14. Half the program instructions are referenced in the program name, namely BR 14 (branch always to the address in register 14) or "branch on register 14". As, on entry to a program, register 14 contained the address to go to terminate the program by whatever invoked it, then that was all it contained in its first version. It was, essentially, the program equivalent of a NOP. Unfortunately, that version had a bug in that the return code was meant to be held in register 15 and this meant it was indeterminate. So a late revision of the program contained another instruction which cleared it was added (SR 15,15 or subtract register 15 from 15). The return code became important when conditional job control execution was used. The first, buggy was just two bytes long, whilst the second, fixed version was 4 bytes long. So, why was a do-nothing program used on IBM mainframes (usually only used in batch jobs)? The answer to that is that it was that IEFBR14 was simply used to allow the surrounding job control language to be invoked. That was typically used to do things like unmount devices and delete what IBM cared to call "datasets" (a dataset might be called a file in other operating systems, although). The JCL step required some executable for all this to be invoked, and hence IEFBRI14 was invoked. In any event, I'm pretty sure that a a QR code is big enough to hold he executable for IEFBR14.

Nice video and Happy April Fools Day! By the way who is sonicmouse?

Hi , like your Channel very much and it's very helpful and detailed.. It would be wonderful if you you do us an Assembly lectures and maybe some advanced tricks

Closest thing to your typical linux package manager *for* windows itself would be _chocolatey_

Ah, good memories with MASM. My first love, among assemblers.

Reminds me of the Nintendo e-Reader, where they managed to fit entire NES games onto dot patterns on paper cards.

Hey! Something I noticed from the QR Code demos I've seen are that the codes used are always massive (understandbly so). With all of the compression techniques utilized, what is the smallest QR Code size that can be used to run a Windows program? (In terms of pixels on the code itself)

Games weighing in at several hundred GB may be more fun. But I find games that fit in a QR code way more impressive

"Is testing cheating?". That is such a great line! Reminds me of the old cartoon where a nervous new developer is standing behind a grumpy grizzled "experienced" programmer. The "experienced" programmer is pounding away on a keyboard attached to a computer with no monitor. He does not even stop typing while he barks at the newbie, "What now? Does the rookie programmer need a monitor?".

Dave, your videos are fascinating. If you would, can you explain what are DirectUIHWND and NetUIHWND window classes that Microsoft now uses for its UI?

Now why should I be surprised my new favourite channel also watches two of my other favourite channels?

LIKE before I hit play because I love watching these challenges. ;)

Just yesterday, I was listening to a Wired Security podcast on MongoDB using indexed, searchable data while maintaining encryption. I immediately thought about QRcodes as an index, wondering how far you could take it and whether it was viable or clunky. Better yet, design your own expandable/compressable format, as a steganography method, utilized by a database or simply file transfer.

I have no idea what he was doing or saying, but it was somehow enjoyable.

I'm glad people know who MattKC is. Anyone seen his latest gameboy micro mod pt2?

"It's weird when you go back and forth" Ain't that the truth!

Great video!

YOU DID IT!!! I love you :)

MattKC did a video of putting a snake game into a QR code. You guys would probably make a good team to do a video together, he got a copy of Windows 98 running on the metal of a 2015 lenovo laptop.

I've literally mentioned MattKC under a Video one week ago!

So now when you go to the doctor's office, the waiting room will be full of "magazines" containing full game QR codes to pass the time. ;)

Dave, what if you tried to fit Spacewar! in a QR code, in collaboration with MattKC? You guys could play a multiplayer QR game together, and use the episode to explain the history of videogames and the size restrictions of such. I don't know if that's your cup of tea, but I'd sure love to see an episode like that!

Awesome! Would it be possible to use that extra 2k bits to render a 3d model? Probably not. It would be cool if the program "drew over" the code, to make it look like the pixels were being rearranged. Maybe form a "secret message"

It would be pretty funny to see the program display the same qr code again

Steve Gibson says "799 bytes?" :D - Keep up the great work!

The idea of mini QR games/apps would be great if they are sandboxed.

This should be a new discipline for the demo scene competitions. Best Demo in a QR Code and Best Game. Now that would be interesting to see how they managed. I know the 4K demos can be freaking impressive, but I wouldn't want to limit them by demanding they provide all the bells and whistles such as moving, resizing and widgets for the window, just that it's using only current and legal system calls and that it cleans up after itself properly and terminate gracefully.

BTW, you might appreciate my executable text encoder: It can take any binary and encode as a text file (like uuencode), but using only the 70+ characters blessed by the MIME standard because they will pass unmodified through all email gateways, even surviving a round trip vie EBCDIC on an IBM mainframe. It uses the absolute minimum possible self-modificating code, only patching in a single two-byte backwards branch in order to terminate the bootstrap decoder loop. I have however never looked at what it would take to do the same as a Windows exe, I am not sure that it would be possible to create a valid EXE header using only those MIME letters?
