WEBVTT 00:00:00.000 --> 00:00:03.220 When you look at your smartphone or you open 00:00:03.220 --> 00:00:06.440 up a new tab on your web browser, it is incredibly 00:00:06.440 --> 00:00:09.060 easy to think of the device in your hand as this 00:00:09.060 --> 00:00:12.730 perfectly sterile cold, calculating machine. 00:00:12.869 --> 00:00:15.830 Right. Like a flawless grid of logic. Exactly. 00:00:16.070 --> 00:00:19.190 Just logic and math, homing away silently beneath 00:00:19.190 --> 00:00:21.829 a sheet of polished glass. Which, I mean, that's 00:00:21.829 --> 00:00:24.050 a very intentional illusion, right? Oh, absolutely. 00:00:24.269 --> 00:00:26.850 The user interface is designed specifically so 00:00:26.850 --> 00:00:29.429 you never have to see the messy, chaotic human 00:00:29.429 --> 00:00:32.350 hands that actually built the underlying architecture. 00:00:32.670 --> 00:00:35.229 And this is the fascinating part. If you bypass 00:00:35.229 --> 00:00:38.450 that interface and you look deep into the raw 00:00:38.450 --> 00:00:41.829 memory of the machine, Like the actual digital 00:00:41.829 --> 00:00:43.950 bedrock of our everyday lives. Down by the machine 00:00:43.950 --> 00:00:46.189 code. Right, you do not just find cold math down 00:00:46.189 --> 00:00:47.950 there. No, you definitely don't. You find jokes, 00:00:48.570 --> 00:00:50.710 you find coffee, or you find these incredibly 00:00:50.710 --> 00:00:54.049 specific, sometimes crude, secret messages left 00:00:54.049 --> 00:00:56.289 behind by the architects. Hidden in plain sight, 00:00:56.289 --> 00:00:59.570 basically. And that is our mission for you today. 00:00:59.740 --> 00:01:02.759 We're taking a custom tailored deep dive into 00:01:02.759 --> 00:01:06.120 a single comprehensive Wikipedia article detailing 00:01:06.120 --> 00:01:09.280 a hidden language known as hexpeak. Hexpeak, 00:01:09.500 --> 00:01:12.140 it's such a great concept. It really is. We are 00:01:12.140 --> 00:01:14.799 going to uncover the deeply human quirks hiding 00:01:14.799 --> 00:01:17.739 inside your devices. And don't worry, you do 00:01:17.739 --> 00:01:19.659 not need to be a software engineer to decode 00:01:19.659 --> 00:01:22.019 them. Not at all. OK, let's unpack this because 00:01:22.019 --> 00:01:24.200 before we can read the secret messages embedded 00:01:24.200 --> 00:01:27.189 in the software. We need to, we need to establish 00:01:27.189 --> 00:01:29.349 the alphabet this hidden language is written 00:01:29.349 --> 00:01:32.629 in. Right. And that alphabet is born out of hexadecimal 00:01:32.629 --> 00:01:34.849 notation. Which sounds intimidating, but it's 00:01:34.849 --> 00:01:36.849 really not. No, it's just a numbering system. 00:01:36.969 --> 00:01:38.930 For anyone familiar with basic computer science, 00:01:38.989 --> 00:01:41.310 you know that at the lowest level, machines process 00:01:41.310 --> 00:01:44.010 binary, right? Ones and zeros. Exactly. Just 00:01:44.010 --> 00:01:46.209 ones and zeros. But reading millions of ones 00:01:46.209 --> 00:01:49.590 and zeros is, well, it's impossible for a human 00:01:49.590 --> 00:01:51.709 programmer to parse. Yeah, your eyes would just 00:01:51.709 --> 00:01:54.890 glaze over. Completely. So to compress that data, 00:01:54.730 --> 00:01:57.870 into something readable, engineers use hexadecimal, 00:01:57.969 --> 00:02:01.069 which is a base 16 numbering system. Okay, so 00:02:01.069 --> 00:02:05.090 base 16. Since base 16 requires 16 distinct characters. 00:02:05.230 --> 00:02:07.969 Right. And we only have the digits 0 through 00:02:07.969 --> 00:02:10.490 9 in our standard numerical system. We run out 00:02:10.490 --> 00:02:13.110 of numbers. Right. So the engineers had to borrow 00:02:13.110 --> 00:02:15.389 from the English alphabet. They incorporated 00:02:15.389 --> 00:02:19.740 the letters A, B, C. D, E, and F. And suddenly 00:02:19.740 --> 00:02:22.099 you have letters mixed directly into the mathematical 00:02:22.099 --> 00:02:24.139 foundation of the software. Which is where the 00:02:24.139 --> 00:02:26.800 trouble starts, right? Oh, human nature guarantees 00:02:26.800 --> 00:02:29.259 it. The moment you give an engineer access to 00:02:29.259 --> 00:02:32.020 letters, they are going to try to spell things. 00:02:32.280 --> 00:02:35.639 Obviously. But the vocabulary is, like, it's 00:02:35.639 --> 00:02:37.280 pretty limited if you only have six letters. 00:02:37.770 --> 00:02:41.210 A through F. Very limited. So according to our 00:02:41.210 --> 00:02:43.909 source material, programmers started utilizing 00:02:43.909 --> 00:02:46.310 visual substitutions. Yeah, getting creative 00:02:46.310 --> 00:02:50.330 with it. Like a zero looks like an O. A one can 00:02:50.330 --> 00:02:53.389 serve as an I or an L. The number five is essentially 00:02:53.389 --> 00:02:57.409 an S. And a seven looks enough like a T. It's 00:02:57.409 --> 00:02:59.250 very visually intuitive once you know the trick. 00:02:59.650 --> 00:03:02.229 And they even started using Rebus -style auditory 00:03:02.229 --> 00:03:04.430 tricks, like using the number eight to represent 00:03:04.430 --> 00:03:07.009 the sound eight. Which really opens up the dictionary. 00:03:07.270 --> 00:03:09.669 Right. So a programmer could spell the word defecate 00:03:09.669 --> 00:03:13.590 in pure machine code by writing D -E -F -E -C 00:03:13.590 --> 00:03:17.110 -8. Classic. Now, I have to push back on this 00:03:17.110 --> 00:03:22.009 a little bit because reading about these substitutions 00:03:22.009 --> 00:03:24.409 instantly transported me back to middle school 00:03:24.409 --> 00:03:26.490 math class. Oh, I know exactly where you're going 00:03:26.490 --> 00:03:29.909 with this. Right. We used to type five five three 00:03:29.909 --> 00:03:32.759 seven eight zero zero eight. into our calculators. 00:03:32.780 --> 00:03:34.620 And turn them upside down. And turn them upside 00:03:34.620 --> 00:03:38.199 down so the screen spelled boob -less. Yep! The 00:03:38.199 --> 00:03:40.300 ultimate middle school prank. So my question 00:03:40.300 --> 00:03:43.419 is, is Hexpeak just the highly paid software 00:03:43.419 --> 00:03:45.740 engineering equivalent of a juvenile prank by 00:03:45.740 --> 00:03:49.199 board coders? Or is there... like a legitimate 00:03:49.199 --> 00:03:51.539 architectural mechanism at play here. What's 00:03:51.539 --> 00:03:54.400 fascinating here is that while Hexpeak absolutely 00:03:54.400 --> 00:03:57.360 relies on a prankster's creativity, it soaps 00:03:57.360 --> 00:04:00.219 a highly critical structural function. Really? 00:04:00.439 --> 00:04:02.919 A structural function? Yes. In the industry, 00:04:03.159 --> 00:04:05.659 these readable strings are known as magic numbers, 00:04:05.719 --> 00:04:09.120 and more specifically, magic debug values. Magic 00:04:09.120 --> 00:04:12.659 debug values. To understand their utility, you 00:04:12.659 --> 00:04:15.819 have to visualize what a system failure looks 00:04:15.819 --> 00:04:18.699 like to a developer. OK, paint the picture. When 00:04:18.699 --> 00:04:21.879 a piece of software crashes, the system generates 00:04:21.879 --> 00:04:24.500 what's called a memory dump. Right. This is a 00:04:24.500 --> 00:04:27.680 complete snapshot of everything in the machine's 00:04:27.680 --> 00:04:30.339 short -term memory at the exact millisecond of 00:04:30.339 --> 00:04:33.240 the failure. Which means the programmer is suddenly 00:04:33.240 --> 00:04:37.050 staring at a screen. containing millions of lines 00:04:37.050 --> 00:04:40.509 of raw, indistinguishable hexadecimal pairs. 00:04:40.629 --> 00:04:43.069 Exactly. It's a nightmare. Finding the line of 00:04:43.069 --> 00:04:45.110 code that caused the crash would be like finding 00:04:45.110 --> 00:04:47.970 a specific grain of sand on a beach. Precisely. 00:04:48.209 --> 00:04:50.430 The cognitive load of scanning abstract data 00:04:50.430 --> 00:04:53.689 is immense. Yeah, I can imagine. But if a developer 00:04:53.689 --> 00:04:56.470 intentionally pre -fills a specific block of 00:04:56.470 --> 00:04:59.230 memory with a recognizable hexpeak word. Oh, 00:04:59.250 --> 00:05:02.170 you see. It acts as a high contrast dye injected 00:05:02.170 --> 00:05:04.529 into a biological system. Wow, that's a great 00:05:04.529 --> 00:05:07.129 analogy. It is a highly functional humanization 00:05:07.129 --> 00:05:09.910 of the data. The human brain is hardwired for 00:05:09.910 --> 00:05:12.269 pattern recognition, so your eyes will instantly 00:05:12.269 --> 00:05:15.089 lock onto a spelled word floating in a sea of 00:05:15.089 --> 00:05:17.850 random math. It just pops out at you. Exactly. 00:05:18.250 --> 00:05:20.730 It immediately orientates the programmer within 00:05:20.730 --> 00:05:22.810 the architecture of the system. Which brings 00:05:22.810 --> 00:05:25.029 into focus how these markers actually operate 00:05:25.029 --> 00:05:27.949 in the wild, because they are primarily deployed 00:05:27.949 --> 00:05:31.089 for debugging, for conducting a postmortem on 00:05:31.089 --> 00:05:33.509 why a system died. Right, they're diagnostics. 00:05:33.569 --> 00:05:36.769 So the most famous Hickspeak words act like digital 00:05:36.769 --> 00:05:39.029 caution tape. They don't just mark a location. 00:05:39.250 --> 00:05:41.769 They identify the specific mechanism of failure. 00:05:41.810 --> 00:05:44.290 And they are overwhelmingly morbid. Yeah, very 00:05:44.290 --> 00:05:46.959 morbid. The classic foundational exam - of this 00:05:46.959 --> 00:05:54.290 is the hex value 0xed DEDBEF. That beef. Dead 00:05:54.290 --> 00:05:56.649 beef. Wait, why dead beef? To understand why 00:05:56.649 --> 00:05:58.810 this specific phrase became an industry standard, 00:05:59.269 --> 00:06:01.149 we have to look at how memory allocation works. 00:06:01.170 --> 00:06:03.689 When a program asks the operating system for 00:06:03.689 --> 00:06:06.490 a chunk of memory to use, that RAM might still 00:06:06.490 --> 00:06:09.490 contain leftover residual garbage data from whatever 00:06:09.490 --> 00:06:11.750 app was using it five minutes ago. Like digital 00:06:11.750 --> 00:06:14.949 ghosts. Exactly. It is uninitialized. If a program 00:06:14.949 --> 00:06:17.110 accidentally reads that uninitialized memory, 00:06:17.449 --> 00:06:20.110 it can cause catastrophic, unpredictable behavior. 00:06:20.329 --> 00:06:23.050 So to prevent the system from trying to process 00:06:23.050 --> 00:06:27.410 random garbage data, the operating system aggressively 00:06:27.410 --> 00:06:30.629 scrubs that newly allocated memory, and it fills 00:06:30.629 --> 00:06:33.939 it entirely with the value Dead beef. That is 00:06:33.939 --> 00:06:36.720 the mechanism. If a developer is scanning a crash 00:06:36.720 --> 00:06:38.980 dump and sees a processor register trying to 00:06:38.980 --> 00:06:41.040 execute dead beef, they know exactly what happened. 00:06:41.100 --> 00:06:43.439 The investigation is instantly over. They know 00:06:43.439 --> 00:06:46.639 immediately that their program grabbed an uninitialized 00:06:46.639 --> 00:06:49.779 invalid memory pointer. It is incredibly efficient. 00:06:49.879 --> 00:06:52.839 It really is. And that specific sequence was 00:06:52.839 --> 00:06:56.540 utilized by early IBM systems, the classic Mac 00:06:56.540 --> 00:06:58.959 OS, the Commodore Amiga. Wow. So it goes way 00:06:58.959 --> 00:07:01.660 back. Oh, yeah. And even today, massive cloud 00:07:01.660 --> 00:07:04.350 infrastructure. providers like Amazon and Citrix, 00:07:04.430 --> 00:07:07.290 they use dead beef to flag virtual machines that 00:07:07.290 --> 00:07:09.649 have hung and died. That's wild. And the language 00:07:09.649 --> 00:07:12.370 of digital death gets even more direct. If you 00:07:12.370 --> 00:07:14.610 are a Windows user, you are likely familiar with 00:07:14.610 --> 00:07:16.569 a blue screen of death. Oh, everyone knows the 00:07:16.569 --> 00:07:19.149 blue screen of death. The actual bug check code 00:07:19.149 --> 00:07:21.750 that the Windows kernel uses to trigger a manual, 00:07:21.850 --> 00:07:24.250 unrecoverable halt of the entire operating system 00:07:24.250 --> 00:07:29.910 is 0xDDDDAD. Dead. Dead, dead. Yeah. But my absolute 00:07:29.910 --> 00:07:32.050 favorite examples in the source material come 00:07:32.050 --> 00:07:34.370 from Apple. They do have some good ones. They 00:07:34.370 --> 00:07:38.519 deploy highly specific narrative hex speak. in 00:07:38.519 --> 00:07:40.980 the crash logs for iOS. They essentially use 00:07:40.980 --> 00:07:43.160 the hex codes to tell a very brief story about 00:07:43.160 --> 00:07:45.699 the error. Right. So think about your own smartphone. 00:07:46.180 --> 00:07:48.660 If you ever tapped on an app and it just hangs 00:07:48.660 --> 00:07:51.639 on the launch screen for like five seconds before 00:07:51.639 --> 00:07:53.399 suddenly crashing back to your home screen. Which 00:07:53.399 --> 00:07:56.199 is so frustrating. It is. Well, your phone's 00:07:56.199 --> 00:07:58.399 background watchdog timer just executed that 00:07:58.399 --> 00:08:00.800 app. And in the crash log, Apple records the 00:08:00.800 --> 00:08:06.579 cause of death as 0X8BADF00D. Ate bad food. Ate 00:08:06.579 --> 00:08:09.579 bad food. It means the application choked on 00:08:09.579 --> 00:08:11.879 something and took too long to launch. I love 00:08:11.879 --> 00:08:14.279 that one. And if an application is running invisibly 00:08:14.279 --> 00:08:16.699 in the background, but it refuses to let go of 00:08:16.699 --> 00:08:18.899 a system resource that another program needs, 00:08:19.519 --> 00:08:22.160 the system creates what is called a deadlock. 00:08:22.699 --> 00:08:25.680 The entire phone would freeze if the operating 00:08:25.680 --> 00:08:28.459 system didn't step in. So the OS kills it. Right. 00:08:28.879 --> 00:08:31.399 And when Apple terminates that background process, 00:08:31.639 --> 00:08:38.000 the log reads 0XDEAD10CC. To me, this dynamic 00:08:38.000 --> 00:08:41.360 is exactly like a digital forensics team, using 00:08:41.360 --> 00:08:45.039 highly specific color -coded chalk outlines at 00:08:45.039 --> 00:08:47.200 a crime scene. That's exactly what it is. Right. 00:08:47.379 --> 00:08:50.480 If you open a massive convoluted crash report 00:08:50.480 --> 00:08:53.179 and you simply see the phrase, ate bad food, 00:08:53.620 --> 00:08:56.259 you instantly comprehend the parameters of the 00:08:56.259 --> 00:08:58.639 failure. Yes. You don't have to cross -reference 00:08:58.639 --> 00:09:00.940 a string of random numbers against a massive 00:09:00.940 --> 00:09:04.039 index manual. The machine is practically talking 00:09:04.039 --> 00:09:06.980 to you in plain English. That highlights the 00:09:06.980 --> 00:09:10.299 brilliant efficiency we're talking about. Troubleshooting 00:09:10.299 --> 00:09:13.379 complex software failures is an inherently high 00:09:13.379 --> 00:09:15.620 -stress, high -stakes environment. Oh, totally. 00:09:15.740 --> 00:09:18.100 Servers are down, money's being lost. Exactly. 00:09:18.299 --> 00:09:21.000 By abstracting a highly technical memory fault 00:09:21.000 --> 00:09:24.279 into a simple intuitive narrative concept, the 00:09:24.279 --> 00:09:27.320 app ate bad food, it forces the engineer into 00:09:27.320 --> 00:09:29.559 immediate critical thinking. It skips the translation 00:09:29.559 --> 00:09:31.840 step. It does. It bridges the gap between the 00:09:31.840 --> 00:09:34.159 rigid reality of the hardware and the intuitive 00:09:34.159 --> 00:09:36.879 leaps of the human mind. The culture of Hexpeak 00:09:36.879 --> 00:09:39.279 isn't purely focused on doom, gloom, and system 00:09:39.279 --> 00:09:41.679 failures, though. No, not at all. Programmers 00:09:41.679 --> 00:09:44.679 also utilize these magic numbers to build monuments 00:09:44.679 --> 00:09:47.200 to the things that fuel them. And in the realm 00:09:47.200 --> 00:09:50.639 of software engineering, that fuel is overwhelmingly 00:09:50.639 --> 00:09:54.200 caffeine. Yes, coffee runs the tech world. We 00:09:54.200 --> 00:09:56.600 see that manifested in another foundational magic 00:09:56.600 --> 00:10:02.179 number, 0XCAFEBABE. Caffe? This one is used as 00:10:02.179 --> 00:10:04.000 a file signature. Okay, what does that mean? 00:10:04.190 --> 00:10:06.529 Well, when an operating system is trying to execute 00:10:06.529 --> 00:10:09.590 a file, it doesn't just blindly trust the file 00:10:09.590 --> 00:10:11.590 extension at the end of the name. Right, because 00:10:11.590 --> 00:10:14.629 anyone could just rename a file to .exe. Exactly. 00:10:14.850 --> 00:10:17.330 So it reads the first few bytes of the actual 00:10:17.330 --> 00:10:20.669 file data to verify what it is looking at. The 00:10:20.669 --> 00:10:22.789 Java programming language requires all of its 00:10:22.789 --> 00:10:25.919 compiled class files to begin with. Caffe, babe. 00:10:26.659 --> 00:10:29.220 And Apple uses the exact same signature for its 00:10:29.220 --> 00:10:31.940 mock -o executable files. But the origin of it 00:10:31.940 --> 00:10:34.539 is wonderfully hyperlocal, right? It is. It was 00:10:34.539 --> 00:10:36.480 originally coined by developers working on the 00:10:36.480 --> 00:10:39.379 Next Step operating system in the late 1980s. 00:10:39.580 --> 00:10:41.820 The jobs' company. Right. And it was a direct 00:10:41.820 --> 00:10:44.039 affectionate reference to the baristas working 00:10:44.039 --> 00:10:47.360 at a nearby Pete's coffee. They literally immortalize 00:10:47.360 --> 00:10:49.759 their neighborhood coffee shop into the underlying 00:10:49.759 --> 00:10:52.039 scaffolding of modern computer science. It's 00:10:52.039 --> 00:10:54.799 beautiful, really. Millions of devices process 00:10:54.799 --> 00:10:57.139 that coffee shop reference every single second 00:10:57.139 --> 00:10:59.940 of the day. Here's where it gets really interesting 00:10:59.940 --> 00:11:03.620 though. It isn't just sleepy, independent coders 00:11:03.620 --> 00:11:06.480 shouting out their baristas. The source material 00:11:06.480 --> 00:11:09.779 details how massive multinational corporations 00:11:09.779 --> 00:11:13.659 are actively using Hexpeak to stamp their brand 00:11:13.659 --> 00:11:16.259 identities right into the bedrock of the internet. 00:11:16.639 --> 00:11:19.120 Oh yeah, we see this heavily in registry keys 00:11:19.120 --> 00:11:21.940 and networking protocols. Microsoft uses the 00:11:21.940 --> 00:11:28.399 hex code 0x000000FF. One CE. Which spells office. 00:11:28.539 --> 00:11:30.940 Spells office. And they hide that deep in the 00:11:30.940 --> 00:11:33.460 registry configurations for its Microsoft Office 00:11:33.460 --> 00:11:36.259 Suite. Sneaky. And it extends far beyond local 00:11:36.259 --> 00:11:39.600 machines into the web itself. Facebook utilizes 00:11:39.600 --> 00:11:44.500 the string face colon B00C in its IPv6 web addresses. 00:11:44.860 --> 00:11:47.379 Cisco incorporates the phrase Cisco dog food 00:11:47.379 --> 00:11:50.960 into its IPv6 addresses, which the source notes 00:11:50.960 --> 00:11:52.899 is a reference to the Silicon Valley phrase, 00:11:53.259 --> 00:11:55.820 eating your own dog food, meaning a company that 00:11:55.820 --> 00:11:58.639 actively uses its own internal products. Right. 00:11:58.799 --> 00:12:01.039 And that transition into network addresses is 00:12:01.039 --> 00:12:04.620 a crucial technical leap. How so? Well, to understand 00:12:04.620 --> 00:12:07.220 how companies are achieving these long vanity 00:12:07.220 --> 00:12:09.240 plates, you have to look at the architecture 00:12:09.240 --> 00:12:13.450 of the internet. The older standard, IPv4, used 00:12:13.450 --> 00:12:16.429 32 -bit addresses, which were strictly numeric. 00:12:16.549 --> 00:12:20.230 Right. Think of an IP address like 192 .168 .1 00:12:20.230 --> 00:12:22.909 .1. Exactly. But we physically ran out of those 00:12:22.909 --> 00:12:26.870 numbers. The new standard, IPv6, uses a massive 00:12:26.870 --> 00:12:30.250 128 -bit address space, and to compress that 00:12:30.250 --> 00:12:32.470 length, the addresses are written entirely in 00:12:32.470 --> 00:12:34.889 hexadecimal. which suddenly provided network 00:12:34.889 --> 00:12:37.269 engineers with a massive blank canvas. A huge 00:12:37.269 --> 00:12:39.450 canvas. They had enough characters to spell out 00:12:39.450 --> 00:12:41.990 entire phrases. But this forces me to ask, these 00:12:41.990 --> 00:12:44.110 corporate vanity plays feel fundamentally different 00:12:44.110 --> 00:12:46.629 than a highly functional dead beef error code 00:12:46.629 --> 00:12:48.850 acting as a debug marker. They are deb - Right, 00:12:49.129 --> 00:12:51.289 because sticking Facebook into a network route 00:12:51.289 --> 00:12:54.009 feels like pure digital territorial marking. 00:12:54.299 --> 00:12:56.980 It's essentially a dog marking a fire hydrant, 00:12:57.120 --> 00:12:59.480 isn't it? If we connect this to the bigger picture, 00:12:59.940 --> 00:13:03.139 you are observing a profound cultural shift within 00:13:03.139 --> 00:13:06.299 the discipline. OK, tell me more. Hexpeak originated 00:13:06.299 --> 00:13:09.039 as a purely functional safety mechanism. Like 00:13:09.039 --> 00:13:11.200 we said, a die in the water to help engineers 00:13:11.200 --> 00:13:14.000 navigate the dark depths of raw memory. Right. 00:13:14.500 --> 00:13:17.039 But as digital systems grew into global infrastructure, 00:13:17.500 --> 00:13:20.820 The language evolved. It transformed into a mechanism 00:13:20.820 --> 00:13:24.379 for brand identity and a signal of insider culture. 00:13:24.580 --> 00:13:27.440 So it became a flex. Exactly. When Facebook routes 00:13:27.440 --> 00:13:29.360 its core traffic through an address containing 00:13:29.360 --> 00:13:32.419 its own name, they are asserting permanence. 00:13:32.559 --> 00:13:34.620 They are weaving their corporate identity into 00:13:34.620 --> 00:13:36.799 the fundamental routing layer of the Internet 00:13:36.799 --> 00:13:40.480 itself. It is a flex of infrastructural dominance. 00:13:40.820 --> 00:13:42.519 But, you know, whenever human beings are given 00:13:42.519 --> 00:13:45.100 a tool to mark their territory, that territory 00:13:45.100 --> 00:13:47.039 inevitably devolves into a battleground. Well, 00:13:47.120 --> 00:13:49.340 absolutely. And that brings us to the intense 00:13:49.340 --> 00:13:52.759 tech rivalries, the open source rebellions and 00:13:52.759 --> 00:13:56.220 the hacker history permanently codified in Hackspeak. 00:13:57.120 --> 00:13:59.659 This is not just a sandbox for massive corporations. 00:14:00.000 --> 00:14:02.320 Not at all. The software engineering world has 00:14:02.320 --> 00:14:05.159 historically been deeply divided between highly 00:14:05.159 --> 00:14:08.679 polished closed source corporate entities and 00:14:08.679 --> 00:14:11.639 fierce decentralized open source communities. 00:14:11.820 --> 00:14:14.259 The classic David and Goliath. Right. And Hexpeak 00:14:14.259 --> 00:14:16.740 frequently becomes the medium where that friction 00:14:16.740 --> 00:14:19.039 plays out. Our source provides a perfect, slightly 00:14:19.039 --> 00:14:21.039 controversial example of this. Oh, the Hyper 00:14:21.039 --> 00:14:24.399 -V thing. Yes. Microsoft developed a virtualization 00:14:24.399 --> 00:14:27.139 system called Hyper -V. When they released it, 00:14:27.440 --> 00:14:29.659 they controversially required that any Linux 00:14:29.659 --> 00:14:31.860 operating system running as a guest inside the 00:14:31.860 --> 00:14:35.299 Microsoft environment use a specific guest signature. 00:14:36.139 --> 00:14:38.139 The hexadecimal code that Microsoft mandated 00:14:38.139 --> 00:14:42.779 the Linux community use was 0xb16b00b5. Big boobs. 00:14:42.899 --> 00:14:45.220 Big boobs. Which, as you might expect, did not 00:14:45.220 --> 00:14:46.919 land well with the open source community. They 00:14:46.919 --> 00:14:49.679 caused an absolute uproar. It was viewed as unprofessional 00:14:49.679 --> 00:14:52.649 and degrading. Understandably. One developer 00:14:52.649 --> 00:14:58.230 formally proposed changing the signature to 0x0defaced 00:14:58.230 --> 00:15:02.049 as a form of silent protest embedded in the code. 00:15:02.110 --> 00:15:04.230 That's pretty clever. Eventually, the backlash 00:15:04.230 --> 00:15:06.889 forced Microsoft to apologize and strip the signature 00:15:06.889 --> 00:15:09.970 out entirely. But the Linux community is no stranger 00:15:09.970 --> 00:15:13.350 to deeply personal hex speak. Oh no, Linux has 00:15:13.350 --> 00:15:16.950 its own deeply embedded secrets. Exactly. If 00:15:16.950 --> 00:15:19.190 you examine the fundamental system calls that 00:15:19.190 --> 00:15:21.649 run the Linux kernel. The command to reboot the 00:15:21.649 --> 00:15:24.470 entire machine requires magic numbers to function. 00:15:24.570 --> 00:15:26.629 Which makes perfect sense from a security standpoint. 00:15:26.870 --> 00:15:29.529 You don't want a rogue process or a stray memory 00:15:29.529 --> 00:15:32.070 pointer accidentally executing a system -wide 00:15:32.070 --> 00:15:34.289 reboot. Right. That would be disastrous. So the 00:15:34.289 --> 00:15:36.750 kernel demands that the developer pass specific, 00:15:37.090 --> 00:15:39.669 hard -coded magic numbers as arguments to verify 00:15:39.669 --> 00:15:41.950 the command is intentional. The primary magic 00:15:41.950 --> 00:15:46.850 number required is 0xfe1dead. Feel dead. Feel 00:15:46.850 --> 00:15:49.049 dead. Which is a brilliant poetic requirement 00:15:49.049 --> 00:15:51.179 for initiat - a reboot sequence. It really is. 00:15:51.259 --> 00:15:53.379 But the secondary magic numbers required just 00:15:53.379 --> 00:15:55.679 look like chaotic random strings of hex. Until 00:15:55.679 --> 00:15:57.740 you translate them back into decimal. Right. 00:15:58.100 --> 00:16:00.639 And when you perform that conversion, the numbers 00:16:00.639 --> 00:16:03.539 reveal something incredibly intimate. Yes. They 00:16:03.539 --> 00:16:05.799 translate perfectly into the exact birth dates 00:16:05.799 --> 00:16:09.080 of Linus Torvalds, the creator of Linux and his 00:16:09.080 --> 00:16:11.220 three daughters. I love this detail. He took 00:16:11.220 --> 00:16:13.620 his children's birthdays, converted them into 00:16:13.620 --> 00:16:16.340 hexadecimal machine code and embedded them as 00:16:16.340 --> 00:16:18.980 the mandatory password for restarting one of 00:16:18.980 --> 00:16:20.980 the most critical operating systems on Earth. 00:16:21.200 --> 00:16:24.059 It is breathtaking. It feels exactly like a Renaissance 00:16:24.059 --> 00:16:27.139 painter sneaking a tiny hidden portrait of their 00:16:27.139 --> 00:16:30.100 family into the background of a massive cathedral 00:16:30.100 --> 00:16:32.330 mural. This raises an important question. about 00:16:32.330 --> 00:16:34.769 the nature of legacy in the digital age. How 00:16:34.769 --> 00:16:37.710 so? Well, unlike physical architecture, software 00:16:37.710 --> 00:16:40.490 is entirely invisible to the naked eye. It has 00:16:40.490 --> 00:16:43.370 no physical monument. True. But Linus Torvalds 00:16:43.370 --> 00:16:46.570 found a mathematical loophole to carve his family's 00:16:46.570 --> 00:16:49.509 name directly into the digital stone. It highlights 00:16:49.509 --> 00:16:52.029 the invisible tug of war we are discussing. Corporate 00:16:52.029 --> 00:16:55.200 versus the personal. Exactly. Hexpeak reveals 00:16:55.200 --> 00:16:57.740 the constant tension between massive corporations 00:16:57.740 --> 00:17:00.059 attempting to stamp their authority on an environment 00:17:00.059 --> 00:17:03.539 and the gritty, deeply personal, irreverent hacker 00:17:03.539 --> 00:17:06.480 communities pushing back. We see that exact same 00:17:06.480 --> 00:17:08.779 hacker pushback manifesting in hardware, too. 00:17:08.900 --> 00:17:11.839 Oh, the PlayStation story. Yeah. The source details 00:17:11.839 --> 00:17:14.400 a fascinating saga. where hackers were attempting 00:17:14.400 --> 00:17:17.160 to reverse -engineer the Sony PlayStation 3. 00:17:17.299 --> 00:17:20.180 A notoriously difficult console to crack. Very 00:17:20.180 --> 00:17:22.740 difficult. They were specifically trying to bypass 00:17:22.740 --> 00:17:26.380 the console's hypervisor to gain direct, unrestricted 00:17:26.380 --> 00:17:29.039 access to the graphics processing unit. Right. 00:17:29.339 --> 00:17:31.480 Sony had locked this hardware down incredibly 00:17:31.480 --> 00:17:34.039 tight to prevent piracy. But when the hackers 00:17:34.039 --> 00:17:35.819 finally cracked the communication protocols, 00:17:36.319 --> 00:17:38.259 they discovered Hexpeak managing the data. And 00:17:38.259 --> 00:17:42.680 what did they find? They found the value 0x1337BEEF 00:17:42.680 --> 00:17:46.720 and 00DBEEF. Leap beef and food beef. Leap beef 00:17:46.720 --> 00:17:49.660 and food beef. And the irony here is just staggering. 00:17:49.819 --> 00:17:53.279 It really is. You have a highly polished billion 00:17:53.279 --> 00:17:56.619 dollar consumer appliance from Sony locked down 00:17:56.619 --> 00:17:59.160 with aggressive corporate security. And deep 00:17:59.160 --> 00:18:02.019 inside that restricted architecture, the engineers 00:18:02.019 --> 00:18:05.539 are using 1990s anti -establishment hacker slang 00:18:05.539 --> 00:18:09.289 Leet to manage the graphics card. It proves that 00:18:09.289 --> 00:18:12.349 underneath the polished corporate suit, the hardware 00:18:12.349 --> 00:18:15.750 engineers still belong to that subversive, shared 00:18:15.750 --> 00:18:17.509 culture. They can't help themselves. No, they 00:18:17.509 --> 00:18:20.670 can't. But to truly appreciate the technical 00:18:20.670 --> 00:18:22.769 achievement of these codes, we have to look at 00:18:22.769 --> 00:18:24.490 how they are actually written. What do you mean? 00:18:24.829 --> 00:18:27.269 Well, because these developers aren't just typing 00:18:27.269 --> 00:18:30.390 words into a text document, they are operating 00:18:30.390 --> 00:18:32.970 within strict grammatical constraints dictated 00:18:32.970 --> 00:18:35.430 by the specific programming language they are 00:18:35.430 --> 00:18:37.490 using. Right. Because the compiler needs to know 00:18:37.490 --> 00:18:39.769 it is looking at a mathematical value, not just 00:18:39.769 --> 00:18:42.750 a random string of text variables. Exactly. Different 00:18:42.750 --> 00:18:45.289 programming languages require distinct prefixes 00:18:45.289 --> 00:18:48.589 or suffixes to flag a value as hex - So they 00:18:48.589 --> 00:18:50.549 have to work around the grammar. This forces 00:18:50.549 --> 00:18:53.349 the coders to utilize incredibly creative workarounds 00:18:53.349 --> 00:18:55.930 to spell their words. Take the C programming 00:18:55.930 --> 00:18:58.769 language, for instance. It requires all hexadecimal 00:18:58.769 --> 00:19:01.589 values to be prefixed with 0x, so programmers 00:19:01.589 --> 00:19:04.609 simply train their eyes to ignore the 0x when 00:19:04.609 --> 00:19:07.230 reading the code. To skip over it. Right. But 00:19:07.230 --> 00:19:10.230 C also utilizes type qualifiers as suffixes. 00:19:10.950 --> 00:19:12.970 A programmer can append an L to the end of a 00:19:12.970 --> 00:19:16.539 number to declare it as a long integer. Oh, which 00:19:16.539 --> 00:19:43.119 means a coder can write 0xdeadcelldcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldeadcelldead 00:19:43.720 --> 00:19:46.220 Feedble. Feedble. And assembly language uses 00:19:46.220 --> 00:19:49.819 a lowercase h as a suffix to define hex. So developers 00:19:49.819 --> 00:19:52.059 can write strings like zero b -e -a -c -h beach. 00:19:52.980 --> 00:19:55.579 Pascal utilizes a dollar sign as a prefix, so 00:19:55.579 --> 00:19:57.740 programmers treat the dollar sign as an s, allowing 00:19:57.740 --> 00:20:00.019 them to spell dollar sign e -e -d seed. It's 00:20:00.019 --> 00:20:02.220 all about finding the loopholes. Visual Basic 00:20:02.220 --> 00:20:05.400 uses an ampersand and an h as a prefix, generating 00:20:05.400 --> 00:20:09.240 words like ampersand, h -e -a -d -e -d headed. 00:20:09.630 --> 00:20:13.230 or my personal favorite, ampersand H -A -D -C 00:20:13.230 --> 00:20:16.930 -0 -F -F -E -E, head coffee. A classic. So what 00:20:16.930 --> 00:20:18.869 does this all mean? When you step back and look 00:20:18.869 --> 00:20:20.829 at all these dialects, it means these brilliant, 00:20:21.309 --> 00:20:23.750 highly compensated engineers are essentially 00:20:23.750 --> 00:20:26.089 playing the world's most restrictive, high -stakes 00:20:26.089 --> 00:20:27.950 game of Scrabble. That's exactly what it is. 00:20:28.089 --> 00:20:32.349 They are trapped inside the absolute rigid mathematical 00:20:32.349 --> 00:20:35.509 constraints of a compiler using every grammatical 00:20:35.509 --> 00:20:37.789 loophole available just to leave a joke behind. 00:20:38.009 --> 00:20:40.329 The Scrabble analogy is perfectly apt. In fact, 00:20:40.509 --> 00:20:42.430 our source points out the ultimate achievement 00:20:42.430 --> 00:20:44.910 in the hexpeak lexicon, the eight -letter hex 00:20:44.910 --> 00:20:47.009 word that happens to hold the highest actual 00:20:47.009 --> 00:20:49.549 Scrabble score. Oh, I love this part. It is the 00:20:49.549 --> 00:20:54.200 crown jewel of the culture. 0XF0CACC1A Focaccia. 00:20:54.299 --> 00:20:57.359 Focaccia. Scoring a massive 17 points in the 00:20:57.359 --> 00:20:59.240 standard English version of Scrabble. Amazing. 00:20:59.380 --> 00:21:01.380 It is a masterpiece of constraint. It perfectly 00:21:01.380 --> 00:21:03.759 summarizes the core beauty of hex speak as a 00:21:03.759 --> 00:21:05.920 phenomenon. Also. It demonstrates that humans 00:21:05.920 --> 00:21:08.740 do not merely want to solve technical problems, 00:21:08.960 --> 00:21:11.259 and we do not just want to write efficient logic 00:21:11.259 --> 00:21:14.079 loops. Right. We inherently need to play. We 00:21:14.079 --> 00:21:17.619 want to create art, find humor, and assert our 00:21:17.619 --> 00:21:20.319 individuality, even within the most strict systemic 00:21:20.329 --> 00:21:23.269 boundaries imaginable. We refuse to be reduced 00:21:23.269 --> 00:21:26.109 to entirely robotic inputs. We fundamentally 00:21:26.109 --> 00:21:29.069 refuse to just be ones and zeros. Exactly! So 00:21:29.069 --> 00:21:32.150 to wrap up our mission today, the next time an 00:21:32.150 --> 00:21:34.619 application suddenly crashes on your phone, or 00:21:34.619 --> 00:21:37.099 your browser hangs, or you look up at a remarkably 00:21:37.099 --> 00:21:40.579 messy, complicated web routing address, take 00:21:40.579 --> 00:21:43.099 a breath. Just pause. Instead of getting frustrated 00:21:43.099 --> 00:21:45.880 at the cold machinery, try to imagine the secret 00:21:45.880 --> 00:21:48.579 jokes, the coffee orders, the dead beefs, and 00:21:48.579 --> 00:21:51.039 the eight bad foods hiding just beneath the surface 00:21:51.039 --> 00:21:53.039 of that screen. Understanding that invisible 00:21:53.039 --> 00:21:55.259 layer completely changes your relationship with 00:21:55.259 --> 00:21:57.519 the technology. It really does. But, you know, 00:21:57.539 --> 00:21:59.359 I think it also leaves us with a highly compelling 00:21:59.359 --> 00:22:01.880 question regarding the future of software. Oh. 00:22:02.250 --> 00:22:05.329 Was that? We are rapidly entering an era where 00:22:05.329 --> 00:22:07.289 artificial intelligence is beginning to write 00:22:07.289 --> 00:22:09.970 and compile more and more of the world's foundational 00:22:09.970 --> 00:22:12.599 code. It's very true of copilot and things like 00:22:12.599 --> 00:22:15.039 that. Algorithms are generating the systems we 00:22:15.039 --> 00:22:17.980 rely on to function. So as human beings begin 00:22:17.980 --> 00:22:20.619 to step back from managing the raw memory blocks, 00:22:21.200 --> 00:22:24.599 will these quirky, weird, perfectly human signatures, 00:22:25.160 --> 00:22:28.279 the cafe babes and the focacias, disappear entirely? 00:22:28.740 --> 00:22:30.839 Wow. Will our future operating systems become 00:22:30.839 --> 00:22:33.799 flawlessly efficient, perfectly optimized, but 00:22:33.799 --> 00:22:36.480 entirely devoid of a soul? That is the real mystery. 00:22:36.779 --> 00:22:39.400 When the digital X -ray machine of our technology 00:22:39.400 --> 00:22:41.920 is finally perfect and all the bugs are squashed 00:22:41.920 --> 00:22:44.460 by an algorithm, we might just realize how much 00:22:44.460 --> 00:22:47.339 we miss the murky, messy human fingerprints we 00:22:47.339 --> 00:22:50.119 used to leave behind. Thank you for joining us 00:22:50.119 --> 00:22:52.279 on this deep dive. Keep looking beneath the surface.
