Sample Use Cases LLMs are increasingly here to stay despite the reservations . How can I use them to enhance my capabilities? Look out for the Gell-Man amnesia effect. You prompt the LLM on some subject you know well. You read the response and see the LLM has absolutely no understanding of either the facts or the issues. In any case, you read with exasperation or amusement the multiple errors in the response, and then ask it about something else, and read the response as if it’s more accurate than the baloney you just read....

Android Calculator Making a precise calculator is not trivial. While \(10^{100} + 1 - 10^{100} = 1\), iOS’s calculator gives back \(0\). explores how Android’s calculator gets this right courtesy of . Real number representations are fundamentally imprecise because we can’t squeeze in infinitely many real numbers into a finite number of bits. Floating-point representations have a base \(\beta\) (assumed to be even) and a precision \(p\), e.g., if \(\beta = 10\) and \(p = 3\), then \(0....

Journals note that prediction services can still make accurate predictions using a fraction of the data collected from a user device. They propose Cloak, which suppresses non-pertinent features (i.e. those features which can consistently tolerate addition of noise without degrading utility) to the prediction task.

Using the training data, labels, a pre-trained model and a privacy-utility knob, they (1) find the pertinent features through perturbation training, and (2) learn utility-preserving constant values for suppressing the non-pertinent data....

I expect reasons like misunderstanding the customer, sunk costs, running out of money (especially with societal pressures like a family to fend for), wrong time, etc. I’d categorize my flashcards web app as a project that never made it....

Crime Drama Ozark’s highlights are Ruth Langmore’s 90s' hip hop playlist, Wendy Byrde’s sociopathic ambition, and Del Rio’s suave. The show follows the Byrde family that has to launder money for the Navarro Cartel. The writers use shortcuts as the show proceeds, and grant excessive plot armor for the Byrde family in subsequent seasons. ’s Bill Dubuque also wrote The Accountant (2016 Film) , which follows a CPA with high-functioning autism who makes his living by uncooking the books of criminal organizations experiencing internal embezzlement....

Debugging 101 Definition? Debugging involves inspecting a program’s internal state. printf Debugging and Logging In printf debugging, one adds print statements and keeps iterating until enough information has been extracted. Using logging has several advantages over printf debugging: varying logging destinations (e.g. standard output, files, sockets, remote servers, etc.); severity levels (e.g. INFO, DEBUG, WARN, ERROR, &c) that support filtering of output; color-coding for readability. Terminals have varying levels of color support: plain color; ANSI escape codes (16 color codes with bold/italic and background); 256 color palette; 24-bit truecolor (“888” colors, aka 16 million, e....

Money was a sore point in the Holmes household. Holmes’s grandparents had squandered away their share of the Fleischmann fortune. Richard Fuisz, a family friend, was a flashy successful businessman. So in a way, Elizabeth didn’t grow up in wealth? This puts a spin on Chapter 01: A Purposeful Life . Fuisz was offended that Elizabeth never consulted him. Fuisz made his money patenting medical inventions that he anticipated other companies would someday want....

How to Be Wrong found that experts were barely able to forecast better than random chance. However, a small subset of people (coined “superforecasters” ) were better. In a competition, they beat teams of top professors and CIA professional analysts. These superforecasters were not smarter than everyone else nor did they have more knowledge/experience, they were great at being wrong. Change your mind a little at a time. Seeing the world in shades of grey is less stressful, as the experience of encountering evidence against one of your beliefs is not high stakes....

Argument from Consequences If God does not exist, then everything is permitted. Straw Man The essence of this technique is to caricature a position to make it easier to attack. My opponent is trying to convince you that we evolved from chimpanzees who were swinging from trees, a truly ludicrous claim. Environmentalists care more for snail darters and spotted owls than they do for people. Appeal to Fear You should give me all your valuables before the police get here....

The Law of the Few From 1995 to 1996, the # of children born in Baltimore with syphillis increased 500%. CDC blamed it on cocaine and reduction in clinics. In 100k+ Colorado Springs town, the gonorrhoea epidemic tipped because of the activities of 168 people living in 4 small neighbourhoods, frequenting the same 6 bars. Gaëtan Dugas, an Air-Canada flight attendant, is [mis?]regarded as “Patient Zero” for AIDS in the US....

Incomplete List of Information Privacy Properties Control/consent, e.g. Cambridge Analytica exfiltrating FB users' data Discussion on Cambridge Analytica Anonymity, e.g. Snowden leaking NSA docs without revealing his identity Limits on data collection, e.g. laws restricting government surveillance Limits on data use, e.g. US Genetic Information Nondiscrimination Act of 2008 Under GINA, health insurers must not use genetic information of the clients (or clients family) to inform their policy....

The Principle Brandolini’s Bullshit Asymmetry Principle: The amount of energy needed to refute bullshit is an order of magnitude bigger than to produce it. In Essence of Bullshit , Frankfurt posits that the essence of bullshit is lack of concern for the truth, which may explain why bullshit is easier to produce. Jonathan Swift: Falsehood flies, and the Truth comes limping after it; so that when Men come to be undeceiv’d, it is too late; the Jest is over, and the Tale has had its Effect…...

Introduction The Tipping Point is the biography of how little things had big effects. From 1992 to 1997, murder rates dropped 64.3% to 770 and total crimes fell by \(\approx\) 50% to 355,893. Geometric progressions are non-intuitive, e.g. if given a large paper and asked to fold it 50x, the stack’s height will be \(\approx\) the distance to the sun. This is a popular illustration. The standard paper’s thickness, \(h_0\), is \(0....

quotes Doug McIlroy: Those types are not “abstract”; they are as real as int and float. What is the context of this quote? A class is a user-defined type provided to represent a concept in the code of a program. Essentially, all language facilities beyond the fundamental types, operators, and statements exist to help define better class or to use them more conveniently....

Day 7 - Advent of Code 2021. adventofcode.com . Accessed Mar 5, 2022. Part I Description A giant whale has decided that your submarine is its next meal, and it’s much faster than you are. There’s nowhere to run! Suddenly, a swarm of crabs (each in its own tiny submarine - it’s too deep for them otherwise) zooms in to rescue you! They seem to be preparing to blast a hole in the ocean floor; sensors indicate a massive underground cave system just beyond where they’re aiming!...

Day 6 - Advent of Code 2021. adventofcode.com . Accessed Mar 2, 2022. Part I Description The sea floor is getting steeper. Maybe the sleigh keys got carried this way? A massive school of glowing lanternfish swims past. They must spawn quickly to reach such large numbers - maybe exponentially quickly? You should model their growth to be sure. Although you know nothing about this specific species of lanternfish, you make some guesses about their attributes....

This page contains remarks on Haskell that I encountered when working with source files that span multiple AoC 2021 problems. and have Haskell solutions. It’ll be nice to compare how they solved the problems. I don’t want to end up perfecting the wrong approach! Setting Up Haskell Env for AoC To manage dependencies, Cabal and Stack are pretty popular. Stack incorporates the Cabal build system....

Problem Statement You are given the following information, but you may prefer to do some research for yourself: 1 Jan 1900 was a Monday. Thirty days has September, April, June and November. All the rest have thirty-one, Saving February alone, Which has twenty-eight, rain or shine. And on leap years, twenty-nine. A leap year occurs on any year evenly divisible by 4, but not on a century unless it is divisible by 400....

Timeline of Secure Multi-Party Communication In 1982, secure two-party computation (2PC) was introduced for problems that are boolean predicates, e.g. Yao’s Millionaires' Problem that asks whether \(a \ge b\) is true without revealing the actual values of \(a\) and \(b\). Andrew Yao generalized 2PC for any feasible computation in 1986. Goldreich, Micali and Wigderson later generalized it to secure multiparty communication. Yao-based protocols requires that the function to be securely evaluated be represented as a circuit, but an efficient transformation is not trivial....

\(X\) is a binomial random variable if it takes the values \(0, 1, 2, …, n\) and $$ \mathbb{P}\{X = k\} = { n \choose k } \cdot p^k \cdot (1 - p)^{n-k} $$ Sanity Check: Do the probabilities sum to 1? $$ \sum_{k=0}^{n} \mathbb{P}\{X = k\} = \sum_{k=0}^{n} { n \choose k } p^k (1 - p)^{n-k} = \left( p + (1 - p) \right)^n = 1 $$ I totally didn’t understand how we got to \(\left( p + (1 - p) \right)^n\)....
