The Official RDrama Computer Science Reading Group

My dear !codecels, hello and welcome to the first meeting of RDrama's Computer Science Reading Group! Here's the idea - we (read: I) pick a computer science textbook, then post a list of sections and exercises from that textbook each week. In the thread, feel free ask questions, post solutions, and bully people for asking stupid questions or posting stupid solutions. If you don't want to read along, I'll post the complete exercises in the OP, so you can solve them without needing to read the book.

SICP

The book I'm starting with is 'the Structure and Interpretation of Computer Programs' (abbreviated SICP). It's a software engineering textbook written by Gerald Jay Sussman and Hal Abelson from MIT. The book builds programming from the ground up: starting with a very simple dialect of Scheme and growing it into a language with lazy evaluation, object-orientation and a self-hosting compiler. It's a fun book: the exercises are hands-on and interesting, the writing is informative without being droll, and both the book itself and a corresponding lecture series (complete with a 80s synth rendition of 'Also Sprach Zarathustra') are available for free online.

Languages

The book uses (a small subset of) Scheme as its primary language, but feel free to try using a different language. The book's dialect of scheme is available through Racket, but most lisps will work with only minor changes. Other dynamically-typed, garbage-collected languages with higher-order functions will also not require much hacking: there is an edition written in JavaScript , as well as a partial adaptation to python . High-level, statically typed languages might also work: Java/Kotlin/C# seem doable, but I don't know those languages well. Strongly typed languages like Haskell will require some real hacks, and I'd avoid doing it in C, C++ or Rust.

Exercises

The book is split into five chapters:

• Building Abstractions with Procedures
• Building Abstractions with Data
• Modularity, Objects and State
• Metalinguistic Abstraction
• Computing with Register Machines

This week, I'll be posting exercises from the first chapter. The chapter is pretty easy for those familiar with programming already, so I just want to get it out of the way. Here are the selected exercises:

Exercise 1.8

Newton's method for cube roots is based on the fact that if y is an approximation to the cube root of x, then a better approximation is given by the value (x/y² + 2y) / 3. Use this formula to implement a cube-root procedure which is wrong by at most 0.01.

Exercise 1.12

The following pattern of numbers is called Pascal's Triangle.

    1
   1 1
  1 2 1
 1 3 3 1
1 4 6 4 1
   ...

The numbers at the edge of the triangle are all 1, and each number inside the triangle is the sum of the two numbers above it. Write a procedure that computes elements of Pascal's triangle.

Exercise 1.18

Devise a procedure generates an iterative process for multiplying two integers in terms of adding, doubling, and halving and uses a logarithmic number of steps.

Exercise 1.31

Write a procedure called product that returns the product of the values of a function at points over a given range (product(l, r,step,f) = f(l) * f(l+step) * f(l + 2 * step) * ... * f(r)). Show how to define factorial in terms of product. Also use product to compute approximations to using the formula π/4 = (2 * 4 * 4 * 6 * 6 * 8 ...) / (3 * 3 * 5 * 5 * 7 * 7 ...)

Exercise 1.43

If f is a numerical function and n is a positive integer, then we can form the nth repeated application of f, which is defined to be the function whose value at x is f(f(...(f(x))...)). For example, if f is the function x → x + 1, then the nth repeated application of f is the function x → x + n. If f is the operation of squaring a number, then the nth repeated application of f is the function that raises its argument to the 2 * nth power. Write a procedure that takes as inputs a procedure that computes f and a positive integer n and returns the procedure that computes the nth repeated application of f. Your procedure should be able to be used as follows: repeated(square,2)(5) = 625

Have fun!

Twitter founder Jack Dorsey is no longer on the board of Bluesky, the decentralized social media platform he helped start. In two posts today, Bluesky thanked Dorsey while confirming his departure and adding that it's searching for a new board member “who shares our commitment to building a social network that puts people in control of their experience.”

The posts come a day after an X user asked Dorsey if he was still on the company's board, and Dorsey responded, without further elaboration, “no.” As TechCrunch points out, Dorsey was on a tear yesterday, unfollowing all but three accounts on X while referring to Elon Musk's platform as “freedom technology.”

Neither Bluesky nor Dorsey himself seem to have said how or why he left the board. For now, two board members remain: CEO, Jay Graeber, and Jabber / XMPP inventor Jeremie Miller. Dorsey originally backed Bluesky in 2019 as a project to develop an open-source social media standard that he wanted Twitter to move to. He later joined its board of directors when it split from Twitter in 2022.

But Dorsey hadn't seemingly been a particularly active participant at the company. In March, when The Verge's Nilay Patel asked Graeber for Decoder about his level of involvement with Bluesky, she said she gets “some feedback occasionally,” but implied he's otherwise “being Jack Dorsey on a cloud,” as Nilay put it. Months before that interview, Dorsey had closed his Bluesky account.

Bluesky did not immediately respond to The Verge's request for comment.

Update May 5th, 2024, 4:37PM ET: Updated with Bluesky's confirmation of Dorsey's departure from its board.

TunnelVision, as the researchers have named their attack, largely negates the entire purpose and selling point of VPNs, which is to encapsulate incoming and outgoing Internet traffic in an encrypted tunnel and to cloak the user's IP address. The researchers believe it affects all VPN applications when they're connected to a hostile network and that there are no ways to prevent such attacks except when the user's VPN runs on Linux or Android. They also said their attack technique may have been possible since 2002 and may already have been discovered and used in the wild since then.

( . . . . )

Interestingly, Android is the only operating system that fully immunizes VPN apps from the attack because it doesn't implement option 121. For all other OSes, there are no complete fixes. When apps run on Linux there's a setting that minimizes the effects, but even then TunnelVision can be used to exploit a side channel that can be used to de-anonymize destination traffic and perform targeted denial-of-service attacks. Network firewalls can also be configured to deny inbound and outbound traffic to and from the physical interface. This remedy is problematic for two reasons: (1) a VPN user connecting to an untrusted network has no ability to control the firewall and (2) it opens the same side channel present with the Linux mitigation.
