not my usual kind of post but i think this is really cool

i stumbled upon this ARG on tiktok lately that poses itself as an investigation into a cancelled Wii peripheral called the Wii Reaffirmation System, and it's included software, Mind Master.

doing things like putting the videos into spectrograms and translating hexadecimal code into plain text, you can find various youtube and google drive links that explain what the system does and how it got scrapped.

currently we are on episode six, and just cracked a puzzle that produced a full report of how the device functions.

if you'd like to watch the series, check out the original creator's page: https://www.tiktok.com/@nebula_animated

and if you'd like to help solve the series, check out this google document that explains how all of the puzzles were solved, and where you can help us continue to research: https://docs.google.com/document/d/1RTU5oP2jAH2ajU5ZsHZFrh7O-UtvwVEtkgS-pkYqvbQ/edit?usp=sharing

Manually Decoding DTMF Through A Spectrogram

While working on a recent CTF, I came across a challenge that required participants to extract a credit card number from a recording of a touch-tone telephone. If you pull your phone out now, turn on your ringer (because it’s almost definitely off), and click on some random numbers on the phone app keypad, you’ll hear the product of what’s known as DTMF, which stands for dual-tone multi-frequency.

I won’t go into the specifics of DTMF and why it exists — the important thing to know is DTMF uses a combination of two distinct tones to create one sound. There is a low tone and a high tone. Today, I’ll be showing you how to decode DTMF by sight through a spectrogram. There are decoders available for free online, so if you come across a problem like this in a CTF, or otherwise, I highly recommend using one of those, purely for speed and convenience. All that being said, this is an interesting process, and just generally a cool thing to know about. It’s the equivalent of converting binary to hexadecimal by hand instead of using an online converter — basically useless — but a great party trick (in the event of attending one, which I highly doubt given you’re reading this — so yeah, basically useless… on that note (or should I say tone (my musically inclined friend has informed me that I should not)), on with the article!)

Note — Standard DTMF — two tones, four levels per tone.

As of iOS 15.7, this tutorial is still relevant. I am looking for more samples (other phone brands and software models) to determine how accurate this is cross-platform. If you’re interested in contributing, there will be some information at the end explaining how.

I’ll be using this audio file - https://voca.ro/1dr1J1gbyw5B

(This is from the CyberSoc Wales “personalbanker” challenge)

The first thing I did was put the recording through a spectrogram program. There are plenty available for free online; personally, I like using Academo, because it includes lines that will help with quick sight-reading later on. (https://academo.org/articles/spectrogram/).

You may be better off downloading software (Audacity is fantastic), should you require a spectrogram for a longer recording. Academo is not scalable beyond 10 seconds, so you can use it, but you’re going to be taking quite a few screenshots.

The first thing I did was drop the recording from the challenge into Academo.

A spectrogram is a visual representation of the frequency content of an audio signal as it changes over time. In the image above, I’ve isolated the beeps produced by the clicking of the phone keypad. This section of the recording is longer than 10 seconds, so I also spliced together two screenshots. Any discrepancies you may notice in the image above are a product of that.

Each vertical line of dots represents one beep, and thus, one number. You’ll notice that there are two horizontal rows per beep, this is the magic of DTMF. There are 8 total frequencies involved in the DTMF system. The original DTMF keypad was laid out in a 4x4 format (below). The letter keys (A, B, C, and D) are no longer used for personal telecommunication. For digital decoding purposes, you will almost certainly not come across the letter keys, although they are still used by amateur radio operators, payphones, and the occasional equipment control system.

I was starting from scratch, with no knowledge of how a spectrogram worked with DTMF, so the first thing I did was create two recordings of myself clicking each number in my phone app (I am using iOS 15.7 on my iPhone XR).

What you’ll begin to notice is that each number has its own combination of low and high tones. If you want to try to figure out the system on your own, now is the time.

Each variation in height represents a tone at a specific Hz. In order to decode this manually, you do not need to know the specific Hz of each number, you just need to understand the relational position of each tone, informed by its Hz.

I ended up throwing the original audio into Audacity so that I could create my own lines on the spectrogram for demonstration purposes.

First, I’m going to turn down the contrast to make it a little easier to see.

Now, I’m going to add some lines to match up the similar tones.

At this point, we have 6 layers of lines, there are no 0s present in this recording, if there were, we would have another line just above the bottom three. The use of the original DTMF structure with the ABCD keys would give us another line above the top three.

The simplest way to proceed is to categorize each set into Low, Medium, and High. You could choose any system — 1, 2, 3; a, b, c; whatever works for you. I recommend the LMH system because it’s visual and easy to keep track of.

I filled out the table below to show each numerical combination.

Two letters per number, each representing Low, Medium, or High (ultra High in the case of 0).

The first letter represents the top layer, and the second letter represents the bottom.

The corresponding Hz are listed in the third row for your reference.

I’ll walk you through the decoding process for the first two and then you can try the third.

We’re going to look at the first column of tones (boxed in yellow).

This represents one number.

The first tone is crossed by the lowest of the top lines, it is marked L.

The second tone is crossed by the medium bottom line, it is marked M.

Together, they are LM — which, upon referencing the chart, is 4.

The second one is MM, which is 5.

Now try the third. (full answer at the end, scroll up now if you’d like to try it on your own — try it with lines or without!)

Once you get a feel for this, the process becomes much faster. The lines are purely for demonstrative purposes, with a little practice you’ll be able to quickly do this without lines.

And that’s how to decode DTMF manually through a spectrogram! Is it useless? Yes! Is it fun? That’s debatable!

If you’d like to help me compare cross-platform DTMF signaling, take a screen recording that captures you pressing 1234567890 on your phone keypad. Send the file to me through one of the methods outlined below. Please include your phone model and its latest software.

language update: are we JSON yet?

one of the things one might want to do with their hobby programming language is, you know, write software using it. so last night, I wrote out a JSON parser using features, both implemented and planned, mostly to see which features I still need to implement. and now I have a list:

classes/custom types (medium difficulty)

augmented assign operators (+=, -=, etc) (easy)

\0 string escape (easy)

slices (medium)

enums (easy)

match expression/statement (medium)

if expressions (instead of statements) (easy-medium)

for loops and iterators (medium)

numeric range generator syntax (probably easy after iterators)

exceptions (medium-hard)

hexadecimal (and other radix) string parsing (e.g. "0x1234".parse_hex()) (easy to implement, medium-hard to keep naming consistent)

lots of small easy features, with a handful of medium to medium-hard. most of the "medium" features aren't so much the technical implementation as they are "how should this operate in this weird specific corner case".

after I get the json parser implemented I'm going to start working on a static site generator, and maybe even come up with a website or blog for this thang so I can stop writing untagged blog posts about it to tungler

Pseudo-historical project about 1912 unit record equipment computation aka the "Symbolic Analyst Processor" full stack!

(above pictures emulate the looks of what this tech stack documentation and actual use may look like, still very early in the process though)

It is still coming together by my head as I write infodump notes and research various aspects of the whole time, (including the WIMP & MERN/MEAN stack) but yk, things are coming together nicely to give some milestone project mid-way between my current phase in life and the next where I go develop a fully alternative INTJ lively stack of tools. Explanations, history dives, lively reaction studies and a couple more content suggestions related to it are on the way.

Behold, the infodumps

Back to the point

The list is far from exhaustive or finished, as life is so much more than meets the eye. But this should be a good start to remind myself what I am working towards, a full revamp of the last ~120 years of history with much attention and care put into making it as satisfying to me as possible, despite the very probable scenario where people take the ideas and incorporate only some of such "modules" in their own workflows. Which is fine but not taking the whole package (and only specific modules) is eventually gonna be a major learning experience for me considering the reason I revamp it all beyond control freak stuff is literally to provide less exclusive / less invasive tools that anyone can learn and customize despite being very... idiosyncratic yk.

Still welcoming suggestions and constructive criticism for such big time, I hope those textual infodumps I do every so often don't bother you too much... Cya soon!

Powers of 2, ranked

32 - As stated in the tags of that other post, I have a special relationship to this one, it was the first power of two I was introduced to and it'll always hold it special in my heart. You know that one post about hyping up your lame boyfriend? That's me and 32. She's special in my heart, and I don't care what you say.

1024 - More than any other power of 2, this one just feels right. Like yeah, 2^10 is 1024. It's the one that breaks the base-10 4 digit barrier, and its power is 10! It's perfect. And it forms the basis of all the other order of magnitude powers - 2^20 ≈ 1 million = 2^10 * 2^10, ofc! And so on. It's a beautiful synergy between two very different bases, and I love it.

2^31, ~2.1 billion - The maximum positive value for a signed integer in most systems. Or, well, one over that, because this is the point where it overflows to negative. It's just such a cool trait, and the one most people are likely to have interacted with in interesting ways that get into the technicalities of modern software development.

256 - The maximum positive value for an unsigned 8-bit integer. This is the overflow point for a lot of NES-era games and earlier, and it's cool for very similar reasons. Very close ranking between 3 & 4. Fun fact: The reason it jumps from 2^8 to 2^32 is because 8 & 32 are themselves powers of 2. And for technical reasons, those form very convenient numbers for indexing positions in memory, because you can store the power of the array in a power-of-two number of bits as well, which is real neat.

64 - The minecraft stack size. Listen, credit where it's due, she's done so much to spread knowledge about powers of 2, probably more than any of the others on this list. I love that minecraft used 64 for its stack size, even though it didn't have to and it's such an unintuitive number.

16 - Hexadecimal is a nice base, I like it. I love that you can represent 256 with two hex digits, and that it can be such a cool little syndication of another important power of 2 in computing.

2048 - I've got a max score in this game, so it's obviously on the list.

2^16 - The max tile in 2048. Okay, well, this is a lie, you can go one higher by filling the entire board, then spawning a 10% chance 4 in the bottom left. I've obtained a 2^17, but never finished a whole game with it. Plus, 2^17 just isn't as pretty as 2^16 - 65,536 feels like it could be a power of 2, it's got that 64 feel. 131,072 doesn't feel like anything.

Understanding Hex Color Codes: How They Work and Why They Matter

In the world of digital design and web development, colors serve not only to enhance visual appeal but also to convey meaning, brand identity, and user experience. They play a pivotal role in shaping how information is perceived and interacted with online. Behind every vibrant website or engaging digital interface lies a sophisticated system of color representation: hex color codes.

These codes are indispensable tools that empower designers and developers to define precise color choices across diverse platforms and devices, ensuring consistency and fidelity to creative intent. This article explores the nuanced workings of hex color codes, shedding light on their intricacies, practical applications, and significance in modern digital media.

Hexadecimal Notation Explained

Hexadecimal, or "hex" for short, is a base-16 numbering system widely used in computing. Unlike our familiar decimal system (base-10), which uses ten digits (0-9), hexadecimal incorporates six additional symbols: A, B, C, D, E, and F, representing values 10 to 15. This system's utility stems from its direct correlation with binary, the fundamental language of computers. Each hexadecimal digit corresponds precisely to a grouping of four binary digits (bits), making it a convenient shorthand for representing binary values in a more manageable and human-readable format.

Components of Color: RGB Model

Colors displayed on digital screens are synthesized using the RGB (Red, Green, Blue) color model. This model operates on the principle of additive color mixing, where different intensities of red, green, and blue light combine to create a vast spectrum of colors. In RGB, each color component can independently vary from 0 (minimum intensity) to 255 (maximum intensity), allowing for precise control over the hue, saturation, and brightness of displayed colors.

Encoding Colors with Hex Color Codes

Hex color codes are a compact and efficient method of specifying colors in digital environments. Represented by a hash symbol (#) followed by six hexadecimal digits (e.g., #RRGGBB), these codes succinctly convey the intensity levels of red, green, and blue that compose a particular color. For instance, the hex code #FF0000 signifies pure red, with the red component at its maximum intensity (FF in hexadecimal) and no green or blue present (00 in hexadecimal).

Understanding Hexadecimal Conversion

Converting RGB values to hex color codes involves translating each decimal (base-10) value of the RGB components into its hexadecimal equivalent. This conversion simplifies the process of specifying colors in web design and graphic editing software, ensuring consistency across different platforms and devices. For example, the RGB value (255, 0, 0) converts directly to the hex code #FF0000, reflecting its pure red composition.

Efficiency and Range of Hex Codes

Hexadecimal notation offers significant advantages in terms of both efficiency and range. By condensing complex RGB values into a concise six-digit format, hex color codes facilitate streamlined communication and implementation of color specifications in digital media. With 16,777,216 possible combinations (16^6), hex codes encompass a comprehensive palette of colors that can be accurately reproduced on various digital screens, ensuring fidelity to designers' creative intentions.

Hex Code Abbreviations

In addition to full six-digit hex codes, abbreviated versions can be used for common colors. This shorthand notation offers several benefits:

Compactness: Reduces the code length to three digits, enhancing readability and efficiency in coding.

Performance Optimization: Helps optimize web page performance by reducing file sizes in CSS and HTML documents.

Ease of Use: Simplifies color specification and editing, particularly in large-scale web projects.

Compatibility: Widely supported across browsers and digital platforms, ensuring consistent color rendering.

For example:

#F00: Represents pure red (#FF0000).

#0F0: Represents pure green (#00FF00).

Practical Applications in Web Design

Hex color codes serve as foundational tools in web design, providing designers with a precise means to specify and manipulate colors across different digital platforms. By incorporating hex codes directly into CSS stylesheets or HTML attributes, designers ensure uniformity and coherence in color schemes, regardless of the viewing device or browser. This approach facilitates seamless adjustments and updates to color palettes throughout the development lifecycle, enhancing both aesthetic appeal and user experience.

Learning and Skill Development

Understanding hex color codes extends beyond practical application in web design, encompassing broader implications for digital media production and software development. Mastery of hex codes equips designers and developers with enhanced control over color manipulation and presentation, fostering creativity and technical proficiency across various digital disciplines. By grasping the nuances of hexadecimal notation and its relationship to RGB color encoding, professionals can elevate their capabilities in graphic design, image editing, and interface development.

Conclusion

In conclusion, hex color codes represent a cornerstone of modern digital design, enabling precise color representation and consistency in an increasingly digital world. By leveraging hexadecimal notation and its applications in the RGB color model, designers empower themselves to articulate visual concepts effectively and create compelling digital experiences. Mastery of hex color codes not only enhances technical proficiency but also enriches creative expression, underscoring their significance as essential tools for contemporary digital professionals.

127.0.0.1:62893: Understanding the Meaning and How to Fix It?

127.0.0.1:62893 is a unique IP address referencing the machine from which you are operating. Working on your computer, have you ever come across the mysterious code 127.0.0.1:62893? Though it seems complicated, knowing its components will be beneficial! The error message "Disconnected from the target VM, address: 127.0.0.1:62893" often shows up on the screen throughout the development process. IPv4 and IPv6 are the two varieties of IP addresses. While IPv6 addresses are 128-bit values written in hexadecimal (e.g., 2001:0b8:85a3:0000:0000:8a2e:0370:7334), IPv4 addresses are 32-bit numbers generally expressed in dotted decimal form (e.g., 192.168.1.1). However, port numbers are used on a device to name particular operations or services. They separate traffic for distinct uses so that several services may run on a single IP address. For HTTP, for instance, online traffic usually uses port 80; for HTTPS, port 443; for SMTP, port 25. This blog post will dissect what 127.0.0.1:62893 represents, how it operates, and how to correct a typical issue. Value In Knowing Network Fundamentals Anyone in IT, networking, or software development needs a strong foundation in network principles. Knowing IP addresses and port numbers enhances security network resource protection, performance optimization, and diagnosis of connectivity problems. Furthermore, it enables experts to set and debug systems properly, guaranteeing seamless connection between devices and services. Summary Of The Subject: 127.0.0.1:62893 An IP address and a port number combine in the address 127.0.0.1:62893. 127.0.0.1 is the loopback address—a special-purpose IP address a host uses to interact with itself. Combined with a port number, it allows local machine testing and development free from system exposure to outside networks. We will examine the details 127.0.0.1:62893 in this blog, including its relevance, typical problems, and recommended methods for diagnosing and maximizing its use. Whether your job is network administrator, developer, or IT enthusiast, knowing this IP can help you to control and fix local network configurations. What Is 127.0.0.1? ( Loopback Address) The most often used loopback address in IPv4 is 127.0.0.1. Reserved for a host to send messages to herself, loopback addresses are a spectrum of IP addresses (127.0.0.0 to 127.255.255). It's a local testing method for network applications without transmitting traffic across the real network. Using 127.0.0.1 causes network traffic to return to the same machine. Because it lets you replicate network environments without impacting other devices, this is very helpful for development, testing, and troubleshooting needs. For instance, if you run a web server on your local computer, you can access it by 127.0.0.1 to guarantee it's operating as it should without letting the internet know. What 127.0.0.1:62893 Can Do for You? There are various benefits to address 127.0.0.1:62893. It gives developers a safe space free from public view by letting them test and troubleshoot programs within. Learning about networking concepts, including TCP/IP systems and client-server communication, benefits one. Early identification and reduction of any security risks depends on local-host traffic monitoring. Debugging helps to identify problems connected to networks, enhancing the stability and performance of applications. Working in a controlled environment, localhost avoids issues with other programs. How to Use 127.0.0.1:62893 The address works as follows in a basic sense: Your device runs an application trying to interact with another process. It wants to interact with a service on the same system, so it uses "localhost," (127.0.0.1). The port number (62893) informs the operating system which service or application should handle incoming traffic. For example, a development tool might utilize this address to interface with a local server for debugging needs. Safety Concerns Although port 62893 and the loopback address are usually safe, there are a few factors to consider: Make sure that your firewall settings allow communication across port 62893 if needed. Blocking this port could stop some programs from operating as they should. If you are unfamiliar with the application or service, be cautious of any software trying to interact with this port. Malicious programs could use this port for illegal correspondence. Now and then, make sure no illegal programs are using any other suspicious port or port 62893 on your machine. Please Note: Even though localhost is designed chiefly for local use, the concepts you gain from experimenting can be used in general networking scenarios. You should now be able to interpret and utilize 127.0.0.1:62893 with ease. The Step-by-Step Troubleshooting Guide STEP 1: Verify whether the service is currently running. Check that the service meant to be listening on 127.0.0.1:62893 is running. Open Command Prompt and run: cmd netstat -an | find "62893". Mac or Linux: Run bash from an open terminal using lsof -i:62893. This command will list the process utilizing port 62893 and indicate whether any service is listening on that port. If no service turns up, start the application or service and try again. STEP 2: Look for port conflicts. Verify no other service makes use of port 62893. If you discover another service, you can stop it or switch the port used for your application. STEP 3: Confirm Firewall Guidelines On particular ports, firewalls can restrict access To be sure port 62893 is permitted, review your firewall settings. Firewall from Windows: Advanced Security Open Windows Defender Firewall Review Inbound and Outbound Rules to find rules blocking Port 62893. Firewall from Apple: Under Security & Privacy, under Firewall Settings in System Preferences STEP 4: Review application settings. To guarantee your program is configured correctly to access 127.0.0.1 and port 62893 Review the configuration files or settings of it. STEP 5: Restart network services Restarts of network services occasionally help to fix underlying problems. Windows: cmd netsh winsock reset Restart the network service using the bash sudo system Linux/Mac. STEP 6: Update or reinstall network drivers Issues can arise from corrupt or antiquated network drivers. Make sure your drivers either reinstall them if needed or are current. Conclusion The combination of a local IP address and a port number utilized by a specific service on your computer is represented as 127.0.0.1:62893, more than simply a string of digits. It is essential for anyone working in web development, networking, or information technology to grasp the significance of port numbers, IP addresses, and local hosts. It is crucial to know how to use localhost and the loopback address 127.0.0.1 while troubleshooting network issues, whether you are a developer testing your latest online application or an IT specialist. If you know what these statistics mean and how to manipulate them, you can keep your local services safe and running efficiently. FAQs Can my browser make an HTTP local request if I am not connected to a network? Indeed, your computer communicates with itself without any network! This is so because your computer connects to a default address—127.0.0.1—which is not particular to any network when it lacks an internet connection. How do IPv6 addresses differ from localhost addresses? Acting as the host entry for any data for a given computer, localhost is the basic IPv4 address stated numerically as 127.0.0.1 together with port 62893. Conversely, IPv6 addresses are a numerical series 127.0.0.1-based internet protocol in the v6 sequence. This is a loopback address, unlike IPv4 addresses, which would not allocate many addresses. Can I block a website using a local host address? If yes, in what manner? Certainly. Just follow a few guidelines as described here: Open Notepad under Administrator; utilize the User Account Control prompt Click File, then Open. View the host file open. Enter 127.0.0.1 in the address bar, then Save and Restart your machine. Read the full article

there's actually another whole ass "shop" theme i started working, like, i've got the entire draft as an acapella on my phone or something, but that kinda got boring. i honestly just didn't wanna go transcribing a whole ass song like that and said "fuck it let's try something different"

so it turns out, after kind of going through a little bit of an adventure, i discovered some things.

what the fuck is a stem. don't tell me actually

what the fuck is an ableton. actually, i know this.

a lot of the songs i write tend to rely on looped patterns, which by themselves are also the formation of of music, in a way. you gotta change 'em here and there, but for the most part, shit Loops

you can represent identities, themes, yadda by what repeats and what doesn't. if you have a brain you can discern that, it's how language works. but the kicker here is that some music making software specializes in letting you throw down some loops that you like and then letting you fuck around with it in the editor for the Big Loop. that's sort of an extreme short generalization of how ableton works.

write some loops, write those loops to the track editor, continue. have some fun with it.

problem is, i don't use ableton. i think it's either that or fruity loops that people use all the time; fruit loops for studio production, ableton for live performances. i think the idea with ableton is that it lets you write stuff on the fly and lets you cook it live, which is cool and all, but again, i don't use it. 'cuz who the fuck has $600 to drop on software.

the goddamn synths to start with cost like that much. fuck off

though when i watched enough sorta tutorials on how that sort of thing works, when i went to go make it work, i looked; i said, what the hell does my DAW do that's like that? turns out it's right here in renoise. this stupid fucking dinky thing

renoise uses "phrases," dawg.

okay, so what the hell is a phrase, then? why not just cook all that in the pattern editor? well, i think the mindset for something like this (if you're not fucking insane, or happen to have probably done this before) is that you go and make something that's known to repeat for a while into the phrase editor, and things which you know is going to change a lot goes into the pattern editor.

here's an idea of what those two look like, by the way

you can probably tell that there's a big fucking difference between "how my shit is arranged" verse "how my other shit that wont change", and that's sort of peak for this kind of thing. this is, essentially, ableton's loop function. you can write things in here, and if you want some new phrase you want to run, you can! you just have to use a specific command (0Zxx where xx denotes the specific phrase to play in hexadecimal) to trigger a new one. this is, essentially, your snap-to-grid track editor for any other DAW. you can also just add shit straight to the bare metal of the track.

needless to say, by using this, it sort of freed up some of the creative room, because if you decide you wanna run some funky bass or just some chords and you don't wanna be stuck here having to do it in a weird way, you throw it into a pattern, boom. if you look in that image above for the pattern editor, that's actually the entire bass. it's a regular ass chord.

hey so here's a whole ass fixed version of trinkets. may god have mercy on your soul. because drums function like they do in literally any other daw (if your daw doesnt work like this, it's stupid. sorry! steinberg made that rule.) then you can also phrase track it like a stock loop and it just works. it's great. i can write so much shit without having to worry about the actual pattern now. this is kind of just what i needed.

if i remember correctly, the way you do this in like, fasttracker or some shit is by writing your phrases or whatever with an instrument or sample or whatever else it is that you're gonna do, and then you just save that as itself a sample, run it in your tracker, and just sample slice backwards if you need the individual bits, otherwise, just say fuck it we ball you have your thing already and then the track is made

see ya
