34 - DNS design iterations
JS and Lance talk about how DNS works and how different improvements have been designed and implemented to overcome a variety of flaws that have arisen over time. Show notes: https://www.randomlytyped.com/34
-
33 - Two Generals' Problem
Lance and JS talk about the Two Generals' Problem and try to understand its real impacts on networked systems. Show notes: https://www.randomlytyped.com/33
-
32 - Lossless compression algorithms
Lance and JS try to make things smaller! In this episode, we explore how to compress information efficiently in a variety of different ways with different tradeoffs. Show notes: https://www.randomlytyped.com/32
-
31 - Signalling System Number 7 (SS7) and phone networks
JS and Lance discover the inner working of the SS7 protocol used in networks by phone carriers, how it’s being abused, and why it’s something we should probably be more concerned about. Show notes: https://www.randomlytyped.com/31
-
30 - How to Bring Down the Internet with Regex
JS and Lance chat about a couple of interesting and very public incidents of a regular expression unexpectedly causing major outages at well-known software companies. We walk through exactly how these incidents happened and discover how easy it is to write a regex with no time complexity guarantees.
-
29 - Great Cannon of China
Lance and JS discuss censoring attacks from China targeting Github. Show notes: https://www.randomlytyped.com/29
-
28 - Software Versioning Schemes
We’re back! JS and Lance are ready to talk about software versioning schemes. Who would have that boiling down complex software systems into a series of numbers would be so hard?
-
27 - Dial-up Modems
Max and JS talk about dial-up modems and try to understand how they work while sharing their nostalgia. Show notes: https://www.randomlytyped.com/27
-
26 - Variance in Type Systems
Type systems can be intimidating. Listen in as JS and Lance struggle to understand type variance! Contravariance, covariance, invariance, bivariance... What do they mean?! Show notes: https://www.randomlytyped.com/26.html
-
25 - CQRS: Command-Query Responsibility Segregation
CRUD isn’t the only way! Lance and JS talk about how separating reads from writes in your domain models can open up a world of possibilities. Show notes: https://www.randomlytyped.com/25.html
-
24 - Protocols Over The Air, Used And Abused
On this episode, Lance and JS discuss the evolution of wireless car unlocking technologies. We talk about some different type of attacks and how they were countered.
-
23 - Immutable Data Structures
Most data structure are only useful if you can modify them. Today, JS and Lance talk about immutable data structure which don't allow for direct modification but instead encourage extension. We consider the situations in which these could be useful and how to build one from scratch.
-
22 - Digital Rights Management (DRM)
JS and Lance discuss the technical and legal implications of digital rights management systems of the past, leading up to the complex and secretive implementations of today.
-
21 - Voting Systems & Arrow's Theorem
JS and Lance continue their conversation about voting systems and ultimately discover how the outcome of an election could possibly be dictated by a single person.
-
20 - Voting Systems & The Condorcet Paradox
Lance and JS examine the social sciences to see what it means to have a fair voting system, and how every system we’ve come up with so far has some fatal flaws.
-
19 - Gödel's incompleteness theorems
Some of the toughest problems in mathematics went unsolved for long periods of time, only for them to be proven hundreds of years later. Can anything and everything eventually be proven with the right level of ingenuity? Gödel's shocking proofs tells us that there are some statements which just...
-
18 - The Halting Problem
We travel back in time to the 1930s to discuss the mathematical landscape which lead to The Halting problem and how a machine constructed as a mental model for a proof defined modern computers.
-
17 - Applied Cryptography and Security
JS and Lance discuss the real-world applications and implications of cryptography with topics like key sharing, password keeping and end-to-end encryption.
-
16 - Asymmetric cryptosystems and digital signing
JS and Lance continue their cryptography explorations by working through an example of RSA, an asymmetric cryptosystem, while discovering its surprising relationship to the concept of digital signatures.
-
15 - History of Symmetric Cryptosystems
JS and Lance are reunited! We go back in time to discover how the earliest cryptosystems worked and cover some ground on the basics of cryptography.
-
14 - The Slow Web
JS and special guest Max discuss the slow web phenomenon and discuss what makes some technological experiences more meaningful than others.
-
13 - P vs. NP, why not both?
We discover why the unsolved P == NP millennium problem is so difficult, and how the ramifications affect our every-day programming.
-
12 - Bloom filters
We talk about Bloom filters, a probabilistic data structure for set membership queries, how they work, and what all the fuss is about.
-
11 - Libra
We explore Facebook's new cryptocurrency and discuss it's potential ramifications on our society and global economy.
-
10 - Prefix Scans
We look at the prefix scan algorithm for the sum operation, and discover how it can be parallelized in a relatively simple but unintuitive way.
-
9 - Accessibility
We discuss the origins of accessibility and how things changed as society moved into the digital age.
-
8 - Distributed Systems Introduction
We go over the fundamentals of distributed systems and get to the bottom of buzzwords like scalability, availability and transparency.
-
7: Technical Debt
We explore the topic of software quality and discover what technical debt actually means.
-
6: Side Projects
We discuss the projects we have been working on in our spare time and what we've learned in the process.
-
5: Transactions, ACID or Just Basic?
In this episode, we discuss the different kinds of database transactions, how they are implemented, and what guarantees they provide.
-
4: Software Licenses
Can I take your code and sell it? We discuss the variety of available licenses and whether they make sense in our current technological landscape.
-
3: Divide and Conquer
In this episode, we discuss divide and conquer algorithms like merge sort, and see why it's more challenging to analyze their complexity.
-
2: To the Hype Train!
Are cryptocurrencies just hype? Probably, but let's still talk about how they were created, their merits and their problems.
-
