Ever since the first person wrote out 5318008 on a calculator, nerds have been hiding secret numbers inside of your PC, and using them to negotiate secret handshakes between applications and files. Today we take a quick look at some of the more entertaining examples.
What are Magic Numbers?
Most programming languages use a 32-bit integer type to represent certain types of data behind the scenes — internally the number is stored in RAM or used by the CPU as 32 ones and zeros, but in the source code it would be written out in either regular decimal format, or as hexadecimal format, which uses the numbers 0 through 9 and the letters A through F.
When the operating system or an application wants to determine the type of a file, it can look to the beginning of the file for a special marker that signifies the type of the file. For instance, a PDF file might start with the hex value 0x255044462D312E33, which equals “%PDF-1.3” in ASCII format, or a ZIP file starts with 0x504B, which equals “PK”, which descends from the original PKZip utility. By looking at this “signature,” a file type can be easily identified even without any other metadata.
Compiled Java Class files start with CAFEBABE
The Linux utility “file” can be used from the terminal to determine the type of a file — in fact, it reads the magic numbers from a file called “magic.”
When an application wants to call a function, it can pass values to that function using standard types like integer, which can be expressed in the source code in hexadecimal format. This is especially true for constants, which are identifiers defined with human-readable names like AUTOSAVE_INTERVAL, but they map to actual integer (or other type) values. So instead of a programmer typing out a value like 60 every time they call the function in the source code, they could use the AUTOSAVE_INTERVAL constant for better readability. (Constants are usually easily recognized because they are written in all capital letters).
All of these examples can fall under the term Magic Numbers, because they might require a specific hexadecimal number in order for a function or file type to work properly… if the value isn’t correct it won’t work. And when a programmer wants to have a little fun, they might define these values using hexadecimal numbers that spell out something in English, otherwise known as hexspeak.
Fun With Magic Numbers: Some Notable Examples
Every AppleScript ends with FADEDEAD
If you take a quick look into the Linux source code, you’ll see that the _reboot() system call on Linux requires a “magic” variable to be passed that equals the hexadecimal number 0xfee1dead. If something tried to call that function without passing in that magic value first, it would just return an error.
The GUID (globally unique identifier) for a BIOS boot partition in the GPT partitioning schemeis 21686148-6449-6E6F-744E-656564454649, which forms the ASCII string “Hah!IdontNeedEFI”, an allusion to the fact that GPT would normally be used in computers that replaced BIOS with UEFI, but it doesn’t necessarily have to be.
0xbaaaaaad – used by iOS crash logging to indicate that a log is a stackshot of the entire system.
0xbad22222 – used by iOS crash logging to indicate that a VoIP app has been killed by iOS because it misbehaved.
0x8badf00d – (Ate Bad Food) used by iOS crash logs to indicate that an application took too long to do something and was killed by the watchdog timeout.
0xdeadfa11 – (Dead Fall) used by iOS crash logging when an app is force quit by a user.
0xDEADD00D – used by Android to indicate a VM abort.
0xDEAD10CC (Dead Lock) used by iOS crash logging when an application locks a resource in the background.
0xBAADF00D (Bad Food) used by the LocalAlloc function in Windows for debugging.
0xCAFED00D (Cafe dude) used by Java’s pack200 compression.
0xCAFEBABE (Cafe babe) used by Java as the identifier for compiled class files
0x0D15EA5E (Disease) used by Nintendo on the Gamecube and Wii to indicate a normal boot happened.
0x1BADB002 (1 bad boot) used by the multiboot specification as a magic number
These aren’t the only ones out there, of course, but just a short list of examples that seemed fun. Know of any more? Tell us in the comments.
Seeing Examples for Yourself
You can see more examples by opening up a hex editor and then opening up any number of file types. There are plenty of freeware hex editors available for Windows, OS X, or Linux — just make sure you are careful when installing freeware to not get infected with crapware or spyware.
As an added example, recovery images for Android phones like ClockworkMod start with “ANDROID!” if read in ASCII format.
Note: don’t go changing anything while you’re looking around. Hex editors can break things!
A file with the .mpeg (or .mpg) file extension is an MPEG video file format, which is a popular format for movies that are distributed on the internet. They use a specific type of compression that makes streaming and downloading much quicker than other popular video formats.
What Is an MPEG File?
Developed by the Moving Picture Experts Group, the same people that brought you such formats as MP3 and MP4, MPEG is a video file format that uses either MPEG-1 or MPEG-2 file compression depending on how it will be used.
MPEG-1 was designed to compress VHS-quality raw video and CD audio down to 1.5 megabits per second without losing too much in quality, making it one of the most popular and widely compatible video/audio formats in the world. Video data for MPEG-1 is normally 30 fps (frames per second), with a resolution of about 352×240.
MPEG-2 was designed to compress video and audio for higher-quality videos and being chosen as the compression scheme for over-the-air digital television, satellite TV services, digital TV, and DVD Video. MPEG-2 video formats can capture video/audio at much higher bitrates than MPEG-1 (around six megabits per second), making it the “enhanced” version. Video data for MPEG-2 is normally 30 fps, with a max resolution of 720×480.
How Do I Open an MPEG File?
Because the fact MPEG video files are so widely compatible, you can open them with many different programs on different platforms, like Windows Media Player, iTunes, QuickTime, and VLC Media Player.
Opening an MPEG file is usually as easy as double-clicking the file and letting your OS decide which program to use. By default, Windows will use Windows Media Player, and macOS will use QuickTime.
Note: Windows users may have to install an MPEG-2 encoder to play this format on Windows Media Player.
If for some reason your OS doesn’t have a default program set up to open MPEG, that can easily be changed on either Windows or macOS. And you most likely won’t even have to do that, because when you install a new app, you can set the association with MPEG files during installation.
Alternatively, if you’d prefer a more robust media player, you might want to download a third-party app. We highly recommend VLC Player. It’s fast, open-source, free, and you can use it on Windows, macOS, Linux, Android, and iOS.
VLC also supports pretty much every file format out there and is a highly capable player. Even Windows users might prefer it to a less-capable app like Windows Media Player.

About OnePlus
OnePlus is a Shenzhen-based start-up and producer of smartphones founded in December, 2013. The company's claim to fame is its bid to offer flagship-level specs in its smartphones, at affordable prices. OnePlus initially sold its smartphones only through an invite system where customers would be sent an invite to purchase smartphones and they had to make the purchase within a fixed time frame. Of late the company has held open sales of its smartphones too.
