#414 – MARCH 31, 2020 View in Browser » Automatically Finding Codenames Clues With GloVe Vectors In the Czech boardgame Codenames, one player must come up with a single-word clue that prompts their teammates to select certain words from a 5×5 board while simultaneously avoiding a “bomb” word that, if selected, causes the team to lose. In this article, James Somers explores how to generate clues automatically using Global Vectors for Word Representations—with surprising results.

Python 101 – Learning About Dictionaries

Dictionaries are another fundamental data type in Python. A dictionary is a key, value pair. Some programming languages refer to them as hash tables. They are described as a mapping object that maps hashable values to arbitrary objects. A dictionary’s keys must be immutable, that is, unable to change. Starting in Python 3.7, dictionaries are ordered. What that means is that when you add a new key, value pair to a dictionary, it remembers what order they were added. Prior to Python 3.7, this was not the case and you…

JVM Ecosystem Survey Results: 2020 Edition

The results of Snyk’s annual survey on the JVM ecosystem are in! Below we take a look at what’s new, what stayed the same, and what surprised us the most. The JVM ecosystem is evolving, and it’s evolving fast. It feels like Java 8 was only released yesterday, but in reality that was over 5 years ago. We’re definitely not getting any younger 😱 In fact, Java 14 already has an early access build available, and Java 11 is making its debut in production. Of course, these are not the…

Implementing Raft: Part 2 – Commands and Log Replication

This is Part 2 in a series of posts describing the Raft distributed consensus algorithm and its complete implementation in Go. Here is a list of posts in the series: Part 0: Introduction Part 1: Elections Part 2: Commands and log replication (this post) Part 3: Persistence and optimizations In this part, we’ll greatly enhance the Raft implementation to actually handle commands submitted by clients and replicate them across the Raft cluster. The code structure remains the same as in Part 1. There are a couple of new structs and…

Minimizing worst case error

It’s very satisfying to know that you have a good solution even under the worst circumstances. Worst-case thinking doesn’t have to be concerned with probabilities, with what is likely to happen, only with what could happen. But whenever you speak of what could happen, you have to limit your universe of possibilities. Suppose you ask me to write a program that will compute the sine of a number. I come up with a Chebyshev approximation for the sine function over the interval [0, 2π] so that the maximum approximation for…

Java Access Modifiers

This tutorial describes Java access modifiers in detail. They control the visibility for Java classes and their members (functions and data). They are public, private, and protected. However, Java also implements a default case when no modifier is present. It means that a class, its functions, fields are only accessible by other classes in the […] The post Java Access Modifiers appeared first on Learn Programming and Software Testing.
