truly love that i got tired of IFs that only have like two women in the main cast and maybe one lesbian per ten i was reading and was like. what if mine was all sapphics? what if all the romance options were dykes. what if i wrote MULTIPLE butch lesbians who weren't just androgynous twinks. what if i wrote an entire story of sapphics defeating the cishetero capitalist patriarchy with the power of their love for each other and the world around them. what if.

Funding FujoCoded: Stretch Goals!
It’s time! With our first goal met (🎉 thank you!), let’s talk about stretch goals. We have quite a few planned, so we're going to go through them one by one and explain what they are and why we chose them!
Tumblr media
Before we go down the list, here's something fun:
Sticker Unlock: At 45 backers, we also unlocked one more sticker!
Tumblr media
The goal of our campaign is to cover business expenses most of all. The unlocked content is an extra token of gratitude for your support that also helps us meet our own targets! 
With that said, let's get to our stretch goals...
$4,000: "That's Why I Ship On Company Time" Ao3 Sticker
At $4,000 we'll unlock one more sticker design that you can add to your collection! 
Our first version of this "shipping" sticker features VSCode and a terminal, but there's more than one type of shipping... here's to the other one!
Tumblr media
$5,000: "Using NPM with Javascript" Article
Next up, we have our first article. Our plan is to add an Articles section to @fujowebdev where we'll collect simple, free guides to help beginners get past the roadblocks we see them encounter!
This first one will cover the basics of NPM, a core element of modern JavaScript!
Tumblr media
"How do I install this JavaScript library? How do I run this open source JavaScript project? How can I get started creating my blog using a tool like @astrodotbuild?" are some of the most common questions we get in our Fandom Coders server. 
Let's give *everyone* the answer!
$6,000: Offering Website Art Prints
Next up, we'll turn the excellent art on our website into prints! These will be (probably) 8x10-sized art prints that will look amazing without breaking the bank. Full specs soon!
Tumblr media
...and speaking of the site, you have tried moving the windows, right?
Tumblr media
$7,000: "Catching Up With Terminal" Article
Next, another common issue for beginner developers: how to start learning how to handle the Terminal.
Tumblr media
This will require some research to determine the major roadblocks, which is how our project operates: active learning from those going through it all!
$8,000: "Crucial Confrontations" Article
And last (for now), something very dear to us: an article extracting some wisdom from the book "Crucial Confrontations": https://www.amazon.com/Crucial-Confrontations-Resolving-Promises-Expectations/dp/0071446524
This may seem like an unusual choice, but it highlights how our teaching goals go beyond programming to cover collaboration!
Tumblr media
After years of working within our community, we repeatedly found that developing effective communication and confrontation skills helps our collaborators thrive. Unfortunately, the world doesn't teach us how to effectively (but kindly) hold each other accountable.
Some of our most involved collaborators have read this book and found the tools within it transformative. Given this experience, we deeply believe that making some of this wisdom easily accessible (without having to read the full book) will allow all of us to collaborate better!
If we can reach $8,000, this will enable us to test this hypothesis and learn how teaching soft skills beyond programming influences what we're able to achieve! It's a bold idea, but we're excited to see how it turns out in practice.
Help us make it there!
And that's all...for now!
If you want to hop on Twitch right now, you can join us as we put some extra polish on our shiny new FujoCoded website.
And remember, you can back our campaign here to help us achieve these goals and more:

how do i... boopbeam.......
I AM SO GLAD YOU ASKED
HOW TO BOOPBEAM UNDER THE CUT
Tumblr media
STRAP IN BOYS THIS IS GONNA BE A LONG ONE
ok so.
you need Bun. It's a JavaScript runtime for the server (your computer). It's what runs the little script I made that automates the booping. Copy-paste the little one-liner into your terminal of choice and hit enter.
2. download this file here. THIS IS THE BOOPINATOR!
3. You'll need a couple pieces of information. What you want to do is go to tumblr.com on a computer, then open up the developer tools. Usually Ctrl (or Cmd) + Shift + I (that's an eye). Head to the tab labelled Network.
4. With the network tab open, boop somebody! However you do it. Either by the boop button next to their name, or the paw icon on their profile. Boop somebody!
5. You should see a new entry in the Network tab labeled "boop". Click on it.
6. You should see a bunch of new tabs to the side. One of them will be named "Headers". Click on that if it isn't already selected.
7. Scroll down to where it says "Request Headers" (NOT RESPONSE HEADERS!) and copy THREE values into the boopinator.ts file you downloaded: • Your "Cookie". Copy that whole value into line 39; replace the bit where it says "YOUR COOKIE HERE" (and keep the quotes!) • Your "Authorization". Copy that whole value (including the "Bearer") into line 38; replace the bit that says "YOUR TOKEN HERE (starts with Bearer)" (and keep the quotes!) • Your "X-Csrf". Copy that value into line 85; replace the bit where it says "FIRST CSRF TOKEN" (and keep the quotes!).
I cannot stress this enough these three values are extremely sensitive and should not be shared ever.
8. In a terminal, navigate to the directory you downloaded boopinator.ts (usually with the cd command) Run: bun boopinator.ts and it *should* start going! Optional 9. You can replace the URLs at the top of the file with the URLs of the people you wanna boop. The script will choose between them at random every time it boops somebody, which is about once per second.
🎉 CONGRATULATIONS you have started the boopbeam! It should now run forever, assuming Tumblr doesn't cut you off. They will eventually, your cookie will expire, but that should be good for about 1000 boops. Occasionally you'll get hit with a 429 error; the script will recover from that automatically, but any other error will cause it to stop in its tracks and wait for you to restart it. An authorization error, for example, means you need to grab those three values again (see step 7).
If you have any questions, my DMs should be open? Or just reblog this post with your question and I'll clarify as much as I can.

just finished the jlox section of Crafting Interpreters
I haven't actually tried to run my interpreter with the class inheritance bits but I do have Some Thoughts about Crafting Interpreters so far:
it's a really good book. I wish I had this however long ago when I started getting interested in compilers and programming language design.
there are a lot of nuggets of wisdom, but to me it feels like the author really likes Ruby and Javascript
I'm surprised he didn't bring up Dart more often, because I'm pretty sure he was heavily involved in its development
he brings up Python often but I think he has not really written much Python. I've complained about he literally just lied about something in Python and then contradicted himself in the very next paragraph. I think he probably googled a lot of stuff about "how to do X in python" and then wrote as if he knew what he was talking about
this dude has got to start learning when to use "else" and "else if" statements. I'm serious, man. I'll teach you how if you're scared
he has an interesting way of writing parsers. normally in a recursive descent parser you will have a function for each grammar rule, like "void expr() { ... }" and "void binaryExpr() { ... }" and "void stmt() { ... }" and "void ifStmt { ... }". and he does this, but each of these is called assuming that all lookaheads have been consumed before calling the function. for example, in the ifStmt production, he will have called "match(IF); match(LPAREN);", and the ifStmt production will start out immediately trying to parse the if expression. maybe I will try writing a parser this way.
also, he grabs all of the tokens at once and shoves them in an array to traverse. this makes sense and makes things easier, I think I usually try to be too clever and write an iterator over tokens and maybe a peek() function with a lookahead or two. but he also has the previous() function available and that is super useful too.
his control flow feels weird sometimes. he'll often do a check of like, "if(method != null) { return method}; throw new RuntimeError("expected a method");" when instead it'd probably make more sense to invert it. it'd be easier to demonstrate what I'm talking about if TUMBLR HAD FUCKING CODE FORMATTING.
anyway overall I'd say this book is 4.5 stars out of 5 so far. not flawless but very much worth your time if you want to get into the world of compilers. I am going to take a small break and then get started working on the clox interpreter. I am very scared to see the type of C that this man will make me write

3, 13, and 18 (you pick if it’s 2023 or 2024 lol) for the Spotify asks please
Hi you 🥰 thanks for asking!! It's music time
3 - Sexiest song
You already beat me to SMOKE AND WATER which whew, top ten played track for a reason. Sleep Token get a free pass since they're like 25% of my wrapped. But Craving by YMIR entered the neurodivergent on repeat loop for a solid week early last year cause it's got some good thuds, but also for lyrics like "your tongue like a knife at my throat" and the ever sexy water/drowning imagery, and kind of breathy, sleazy delivery of the vocals. I'm easy okay
13 - The song with the most peculiar sound (to you)
I am Shell I am Bone by Gazelle Twin, which is from my Xeheia's Fold playlist. I sought out mostly unusual, sometimes unsettling sounding tracks for it, give or take a few bops. I love this track for Xeheia - The strange eldritch trills, the slightly discordant doubled vocals, and the lyrics "I am young and I am old" in particular, as the Fury is a relatively new incarnation borne of Zadar's influence, while the Watcher herself is ancient. And shell and bone is, of course, what Gab's focus is made of.
18 - A song that describes your year so far
Literal Legend seems to have been wiped off Spotify, but if it hadn't been it would be this one. Only joking, this is actually the hardest one to answer since there's nothing that tracks! Or at least that I want to announce publicly lmao. I guess my crash course in javascript is putting me on a RAMPAGE both in frustration and triumph is that anything

Zillow Scraping Mastery: Advanced Techniques Revealed
Tumblr media
In the ever-evolving landscape of data acquisition, Zillow stands tall as a treasure trove of valuable real estate information. From property prices to market trends, Zillow's extensive database holds a wealth of insights for investors, analysts, and researchers alike. However, accessing this data at scale requires more than just a basic understanding of web scraping techniques. It demands mastery of advanced methods tailored specifically for Zillow's unique structure and policies. In this comprehensive guide, we delve into the intricacies of Zillow scraping, unveiling advanced techniques to empower data enthusiasts in their quest for valuable insights.
Understanding the Zillow Scraper Landscape
Before diving into advanced techniques, it's crucial to grasp the landscape of zillow scraper. As a leading real estate marketplace, Zillow is equipped with robust anti-scraping measures to protect its data and ensure fair usage. These measures include rate limiting, CAPTCHA challenges, and dynamic page rendering, making traditional scraping approaches ineffective. To navigate this landscape successfully, aspiring scrapers must employ sophisticated strategies tailored to bypass these obstacles seamlessly.
Advanced Techniques Unveiled
User-Agent Rotation: One of the most effective ways to evade detection is by rotating User-Agent strings. Zillow's anti-scraping mechanisms often target commonly used User-Agent identifiers associated with popular scraping libraries. By rotating through a diverse pool of User-Agent strings mimicking legitimate browser traffic, scrapers can significantly reduce the risk of detection and maintain uninterrupted data access.
IP Rotation and Proxies: Zillow closely monitors IP addresses to identify and block suspicious scraping activities. To counter this, employing a robust proxy rotation system becomes indispensable. By routing requests through a pool of diverse IP addresses, scrapers can distribute traffic evenly and mitigate the risk of IP bans. Additionally, utilizing residential proxies offers the added advantage of mimicking genuine user behavior, further enhancing scraping stealth.
Session Persistence: Zillow employs session-based authentication to track user interactions and identify potential scrapers. Implementing session persistence techniques, such as maintaining persistent cookies and managing session tokens, allows scrapers to simulate continuous user engagement. By emulating authentic browsing patterns, scrapers can evade detection more effectively and ensure prolonged data access.
JavaScript Rendering: Zillow's dynamic web pages rely heavily on client-side JavaScript to render content dynamically. Traditional scraping approaches often fail to capture dynamically generated data, leading to incomplete or inaccurate results. Leveraging headless browser automation frameworks, such as Selenium or Puppeteer, enables scrapers to execute JavaScript code dynamically and extract fully rendered content accurately. This advanced technique ensures comprehensive data coverage across Zillow's dynamic pages, empowering scrapers with unparalleled insights.
Data Parsing and Extraction: Once data is retrieved from Zillow's servers, efficient parsing and extraction techniques are essential to transform raw HTML content into structured data formats. Utilizing robust parsing libraries, such as BeautifulSoup or Scrapy, facilitates seamless extraction of relevant information from complex web page structures. Advanced XPath or CSS selectors further streamline the extraction process, enabling scrapers to target specific elements with precision and extract valuable insights efficiently.
Ethical Considerations and Compliance
While advanced scraping techniques offer unparalleled access to valuable data, it's essential to uphold ethical standards and comply with Zillow's terms of service. Scrapers must exercise restraint and avoid overloading Zillow's servers with excessive requests, as this may disrupt service for genuine users and violate platform policies. Additionally, respecting robots.txt directives and adhering to rate limits demonstrates integrity and fosters a sustainable scraping ecosystem beneficial to all stakeholders.
Conclusion
In the realm of data acquisition, mastering advanced scraping techniques is paramount for unlocking the full potential of platforms like Zillow. By employing sophisticated strategies tailored to bypass anti-scraping measures seamlessly, data enthusiasts can harness the wealth of insights hidden within Zillow's vast repository of real estate data. However, it's imperative to approach scraping ethically and responsibly, ensuring compliance with platform policies and fostering a mutually beneficial scraping ecosystem. With these advanced techniques at their disposal, aspiring scrapers can embark on a journey of exploration and discovery, unraveling valuable insights to inform strategic decisions and drive innovation in the real estate industry.

GitHub Repositories Hit by Password-Stealing Commits Disguised as Dependabot Contributions
Tumblr media
A new deceptive campaign has been observed hijacking GitHub accounts and committing malicious code disguised as Dependabot contributions with an aim to steal passwords from developers.
"The malicious code exfiltrates the GitHub project's defined secrets to a malicious C2 server and modify any existing javascript files in the attacked project with a web-form password-stealer malware code effecting any end-user submitting its password in a web form," Checkmarx said in a technical report
The malware is also designed to capture GitHub secrets and variables to a remote server by means of a GitHub Action.
The software supply chain security firm said it observed the atypical commits to hundreds of public and private GitHub repositories between July 8 and 11, 2023.
It has emerged that the victims had their GitHub personal access tokens stolen and used by the threat actors to make falsified code commits to users' repositories by posing as Dependabot.
Dependabot is designed to alert users of security vulnerabilities in a project's dependencies by automatically generating pull requests to keep them up-to-date.
Tumblr media
"The attackers accessed the accounts using compromised PATs (Personal Access Token) -- most likely exfiltrated silently from the victim's development environment," the company said. Most compromised users are located in Indonesia.
However, the exact method by which this theft may have taken place is currently unclear, although it's suspected that it may have involved a rogue package inadvertently installed by the developers.
This is evidenced by a new data exfiltration campaign targeting both npm and PyPI that uses as many as 39 counterfeit packages to gather sensitive machine information and transmit the details to a remote server.
The development highlights the continued attempts on part of threat actors to poison open-source ecosystems and facilitate supply chain compromises.

I'm sure a lot of people are wondering how we got to this point.
As someone who's basically worked on all aspects of a computer save for chip design, the answer mostly boils down to layers, abstraction or otherwise (and subsequently, security).
The Apollo rocket's code was written largely by a core of 40-70 programmers, IIRC (and depending on how you define "core"). Everything else was either done by one of the 300 odd other programmers at NASA or cribbed from some academic paper somewhere. Everything had access to everything else; if the radio wanted to blink out its error message in morse code using the cabin's "check engine" light, it could. Nothing was stopping you, other than likely getting smacked upside the head by someone 4 cubicles down.
Meanwhile, a chrome tab involves so many elements and so many permissions that it makes the UN look like a NASCAR pit crew. Say you're building a website that just wants to automatically log you in, nothing else.
Well, you're likely building this in a framework, so before you even interact with the browser you're using mode.jk or something. One layer. You call the function to get the user session token. Your framework looks at the session info and figures out what kind of browser it's running on. IE7. Framework figures okay, we've gotta formulate the request using these depreciated functions that haven't been touched since 2009. Two layers. Browser cocks its head at you and goes "Okay pal, who's asking?" Your code fumbles for its passport showing it already has permission to access cookies. Three layers. The browser double checks your site's passport against the SSL token to make sure it wasn't handed a forgery, everything checks out. Four layers. Confident the request was genuine, the browser asks the operating system for access to the contents of the current executing directory, the user/IE7/cookies directory, the temp/currentsession/cookies directory, and recites the ancient bitmask of legend indicating the secret windows directory where IE actually stores the cookies. Five layers. Windows, busy with other things, asks the browser to hold on for a microsecond.
After a couple of them it finally grunts "papers, please" and then ensures the browser has permission to access to all these directories. Six layers. Satisfied, it gives them a magic number for the cubicle containing the function that will actually give the contents of those files. The browser approaches this address, asks "hey, so do any of those directories have a file named mysite.cookie on here?" A familiar refrain rings out. "Maaaaybe... Who's asking?" Seven layers. After confirming your browser's papers once again, it references seven different indices and writes up a request slip before waddling down to the hard drive and knocking on a door. "Hey, got a request for contents at chunk 87, sector 9, bytes 2,874 through 2,996!" Hard drive gives the slip a look and replies "Okay, expect your delivery to arrive within 5-7 business milliseconds." Eight layers.
12 milliseconds pass.
Eventually the raw text of the cookie file reaches the function you requested it from and it throws the papers in a stack at you. "My work here is done." The browser trudges back through the checkpoint while Windows Defender rifles through your browser's memory for viruses with all the effectiveness of the TSA. Nine layers. A bell jingles as the browser enters through the door of your framework and throws all the papers on its desk in a pile. The jingle rings out again as the browser's work is finally done. Ten layers. Your javascript framework, realizing it's working with IE7, grabs scissors and cuts out the relevant token, packaging it up in the latest json specification and throwing it down the function return chute. Eleven layers. However, since this is a promise function and javascript doesn't support true multithreading, the return package languishes for hundreds of microseconds until javascript gets around to checking it. Twelve layers.
Hey, your session token is here! Unfortunately, the cookie was created by a chrome browser. Due to a hitherto undiscovered bug in mode.jk, the token's expiration date was stored in unix timestamp format, but the framework assumed it was created by the browser you're using, which would have stored the date in MMDDYYYHHSS format, and the misinterpreted data claims this token expired in 1979.
Would you like to create an account?
we should globally ban the introduction of more powerful computer hardware for 10-20 years, not as an AI safety thing (though we could frame it as that), but to force programmers to optimize their shit better

Web3 Crypto Jobs: A Growing Opportunity
The world of technology is always changing, and one of the latest developments is the rise of Web3 and cryptocurrency (crypto). These new technologies are creating exciting job opportunities for people around the world. If you're interested in tech and finance, Web3 Crypto Jobs might be the right fit for you. This article will help you understand what Web3 and crypto are, and what types of jobs are available in this growing field.
Tumblr media
What is Web3?
Web3 is a new version of the internet that uses blockchain technology. Unlike the internet we use today, where big companies control most of the data, Web3 allows users to have more control. Blockchain is the key technology behind Web3. It’s a system where data is stored in a way that is secure, transparent, and can’t be changed. This makes Web3 safer and more private compared to the current version of the internet, known as Web2.
In Web3, users can own their own data, and everything is decentralized. This means there’s no single company or person in charge. Instead, the system is run by many people around the world. Web3 also allows for new types of applications, like decentralized apps (dApps) and digital currencies (cryptocurrencies).
What is Crypto?
Cryptocurrency, or crypto for short, is a digital form of money. It uses blockchain technology to work without needing a central authority, like a bank. Bitcoin is the most well-known cryptocurrency, but there are thousands of others like Ethereum, Ripple, and Litecoin.
Cryptocurrencies can be used to buy things, send money to people around the world, or as an investment. Because they are based on blockchain, transactions are fast, secure, and often cost less than using traditional money systems. Cryptocurrencies are also a big part of Web3, as they provide the fuel for many Web3 platforms and dApps.
Web3 Crypto Jobs: What Are They?
As Web3 and cryptocurrencies continue to grow, so do the job opportunities in this field. Companies need talented people to help build, maintain, and improve these new technologies. Here are some of the most common Web3 crypto jobs:
1. Blockchain Developer
Blockchain developers are responsible for creating and managing blockchain systems. They write the code that makes blockchain work and help build dApps, smart contracts, and other blockchain-based tools. To become a blockchain developer, you need to know programming languages like Solidity, Python, or JavaScript.
2. Smart Contract Developer
Smart contracts are a key part of blockchain technology. They are self-executing contracts with the terms of the agreement written into the code. Smart contract developers create and test these contracts to make sure they work properly. Most smart contracts are built on platforms like Ethereum, which means knowing the Solidity programming language is important.
3. Crypto Community Manager
Crypto projects often have large online communities, and a crypto community manager helps keep these communities engaged and informed. They interact with users on social media, answer questions, and provide updates about the project. Community managers play a key role in keeping users excited and building trust in the project.
4. Web3 Product Manager
Product managers oversee the development of new Web3 and crypto products. They work with developers, designers, and marketers to bring new ideas to life. A product manager in the Web3 space needs to understand both the technology and the needs of the users. They ensure the final product is something that people will find useful and easy to use.
5. Crypto Analyst
Crypto analysts study the market and help companies make informed decisions about investments, trading, and strategy. They look at trends in cryptocurrency prices and trading volumes, and they may also give advice on which coins or tokens to invest in. Crypto analysts need to have strong research and analytical skills, as well as a deep understanding of the crypto market.
6. Security Engineer
Because blockchain and crypto involve money and valuable data, security is a top priority. Security engineers help protect these systems from hacking and other types of attacks. They look for weaknesses in the code, create ways to keep the system safe, and respond to security threats. This job is important in making sure users feel confident using Web3 and crypto platforms.
7. Crypto Content Writer
Crypto content writers create blogs, articles, and social media posts that explain complex topics related to Web3 and crypto in a simple way. They help educate the public about new technologies, products, and trends. Good writing skills and an understanding of crypto are important for this role.
