A Bloom filter is a probabilistic data structure present in many common applications. Its purpose is answering the question: “is this item in the set?” very fast and not using a lot of space. The answers can be NO, or MAYBE YES. They work using hash functions, we learned about them some time ago. For example, one use case of Bloom filters is the following: you have a huge list of malicious URLs. In your browser, before a user navigat..

Humans are prone to manipulations by their own experiences and biases. Let's review what are some of the cognitive biases and cultural weaknesses that make us fall for all sort of things on the internet. We've already looked at coercion, deception, and other types of persuasion principles in a previous sections. In the following two we'll emphasize on ourselves instead of external factors.

I'm evaluating new SaaS business ideas, and I wanted to share a little bit about exactly how I'm evaluating them.

I’m graduating from college in May. Over my four years working towards my degree, I’ve taken about forty different courses. As I enter the last month of school, I thought it would be a good time to look back and reflect on the courses that I enjoyed the most. I’ve picked out five classes, and instead of trying to make any absolute ranking of them, I just decided to present them in the order they were taken, and try and express how each one ....

Today, I increased my monthly donation to Zig to $200 a month. Before Zig, I have not contributed financially to any open source project. Before I can explain why I am so extremely excited about the Zig programming language and its community, I need to explain where I come from.

Introduction You write a server for a massively multiplayer online role-playing game ( MMORPG ). In the game, players collect keys and you want to design how to store the set of keys each player has. As an example, imagine the set of keys are copper, jade and crystal. You consider the following options for storing a player key sets: []string map[string]bool Both options will work, but did you consider a third option of using a bit..

What a fascinating read. It sits right at the intersection of two of my (too many) vicious interests: Jazz music and books. Since the mid-1970s, almost every jazz musician has owned a copy of the same book. It has a peach-colored cover, a chunky, 1970s-style logo, and a black plastic binding. It’s delightfully homemade-looking—like it was printed by a bunch of teenagers at a Kinkos. And inside is the sheet music for hundreds of common j..

Introduction Ben Hoyt wrote an excellent blog post comparing programming languages with a non-trivial program: counting the number of words in a text file. You can find his repo here . Of all of the languages, only C did not provide a hashmap out of the box, so Ben wrote a simple linearly probed map with a simple hash function for his version. As it turns out, I have already written what is supposed to be a production-ready ..

We’re pleased to announce our new plugin for JetBrains IDEs, making it easier for developers to find and fix security issues as they code!

I did a recent AMA on Clubhouse and there were a lot of awesome, hard-hitting questions on the panel. So for the next several weeks, I’m going to write out my thoughts to each of the questions and how I answered them.

Here is a simple question. Given the lisp function below (and that the function is not advised) what will the output be of (foo)? (defun foo () "foo") Seems pretty simple right? How could the answer be anything other then "foo"? It is just returning a constant string. Or is it? The real answer to this question is… We have no idea. It can could be any string of length 3.

For example, if you want to run an analysis only on users that are on your pro plan , you can do that by adding a “plan” trait to your users. The value of these properties is mutable and has no relationship with time. We’re thinking about making it immutabl..

I never see my macOS desktop. It’s always cluttered with way too many open windows. When I spot those fantastic, tidy and clean Desktops on the internet, I envy their owners. I wonder if and how they manage to keep those desktops tidy like that the whole workday. It must feel so good. I try to keep my windows well arranged. The typical setup might be two windows, from two different apps, tiled side by side. Maybe the browser, or Postman, ..

In previous posts, I suggested two modifications of the Harrell-Davis quantile estimator: winsorized and trimmed . Both modifications have a higher level of robustness in comparison to the original estimator. Also, I discussed the efficiency of the Harrell-Davis quantile estimator. In this post, I’m going to continue numerical simulation and estimate the efficiency of the winsorized and trimmed modifications.

What is a Bloom Filter? A Bloom filter is a probabilistic data structure. It tells you if an element is in a set or not in a very fast and memory-efficient way. A Bloom filter can tell if an element is not in the set (“being 100% sure”) or that it may be in the set, but not “being 100% sure”. It only has 2 operations: add, to add an element, and query, to check if an element exists in the set or not.


Since ancient times, nations have tried to write history from their own point of view. As they say, history is written by the victors. Today, the speed of the internet allows rewriting the narrative in real-time, and state actors will certainly take advantage of this. Namely, there are two ways, or generations, of state information-control practices, an information scarcity approach, aka censorship, and an embracing of information approach,..

The times that I've made the least progress on writing was when I was trying to do it on the side or as a hobby. This isn't because of the relative amount of time I devoted to it. It was because I treated it as something I would try to fit in, and it never did. I could always find something else to do.
