A ggplot2 Tutorial for Beautiful Plotting in R - Cédric Scherer
Introductory Words I don’t care, just show me the content! Back in 2016, I had to prepare my PhD introductory talk and I started using {ggplot2} to visualize my data. I never liked the syntax and style of base plots in R, so I was quickly in love with ggplot. Especially useful was its faceting utility. But because I was short on time, I plotted these figures by trial and error and with the help of

Man Who Built The Retweet: “We Handed A Loaded Weapon To 4-Year-Olds”
The Man Who Built The Retweet: “We Handed A Loaded Weapon To 4-Year-Olds”The button that ruined the internet — and how to fix it. Developer Chris Wetherell built Twitter’s retweet button. And he regrets what he did to this day. “We might have just handed a 4-year-old a loaded weapon,” Wetherell recalled thinking as he watched the first Twitter mob use the tool he created. “That’s what I think we a

Microsoft finds new elevation of privilege Linux vulnerability, Nimbuspwn | Microsoft Security Blog
Microsoft has discovered several vulnerabilities, collectively referred to as Nimbuspwn, that could allow an attacker to elevate privileges to root on many Linux desktop endpoints. The vulnerabilities can be chained together to gain root privileges on Linux systems, allowing attackers to deploy payloads, like a root backdoor, and perform other malicious actions via arbitrary root code execution.

Rusts type system requires that there only ever is one mutable reference to a value or one or more shared references. What happens when you need multiple references to some value, but also need to mutate through them? We use a trick called interor mutability: to the outside world you act like a value is immutable so multiple references are allowed. But internally the type is actually mutable. All
Opinion | No Single Player Can Win This Board Game. It’s Called Pandemic. (Published 2020)
Our new reality became very immediate for my wife Donna and me in late February, when she came down with nasty, flulike symptoms and couldn’t get tested for the coronavirus for four long weeks. When she finally did, we were relieved the test came back negative. But this felt personal in more ways than one: Donna was the inspiration for Pandemic, a board game that was originally released in 2008. I

データアナリティクス事業本部の鈴木です。 Lassoは、例えばscikit-learnを使うと簡単にクロスバリデーション（以降CV）で正則化パラメータとそのときの回帰係数を推定できます。一方で、単にCVで最適なモデルを求めるだけではなく、解パス図を描いて回帰係数の変化を詳しくみたり、CVで求めた値を使ってより簡単なモデルを選択したりしたいと思ったので、scikit-learnの関数を使って試してみました。 Lassoとは Lassoは線形回帰モデルの回帰係数の推定法の一つで、係数の推定時にいくつかの係数を0にすることで変数選択を行える手法です。 以下のように回帰係数のL1ノルムを正則化項として誤差二乗和に付けた関数を、回帰係数について最小化することで回帰係数を推定します。 ただし、L1ノルムは以下です。 例えば2変数の場合、以下の斜線部に誤差二乗和部分（第1項目）の解βLSが入る場合にその

The Future of Work is Not Corporate — It's DAOs and Crypto Networks - a16z crypto
In the future, it’s likely that the average person will not work for a company. Instead, people will earn income in non-traditional ways by taking actions such as playing games, learning new skills, creating art, or curating content. This kind of shift in how we work is not unusual or unexpected — the idea that most people would be employed by large corporations would have seemed crazy to someone

Finding good data and a good policy correspond to optimizing the lower bound, $F(\theta, q)$, with respect to the policy parameters and the experience. One common approach for maximizing the lower bound is to perform coordinate ascent on its arguments, alternating between optimizing the data distribution and the policy.1 Optimizing the Policy When optimizing the lower bound with respect to the pol
