Thursday evening I organized a meetup called Data Science: Inconvenient Truths where the amazing Diyang Tang, Clare Corthell, and Elena Grewal told great stories about things that have gone wrong when doing machine learning or data analysis. Elena gave a talk (video of a previous version) about common mistakes you can make when running experiments. I was super excited to hear her talk because I’m

You may have heard that the NSA can decrypt SSH at least some of the time. If you have not, then read the latest batch of Snowden documents now. All of it. This post will still be here when you finish. My goal with this post here is to make NSA analysts sad. TL;DR: Scan this post for fixed width fonts, these will be the config file snippets and commands you have to use. Warning: You will need a re

A technical comparison of various SSH implementations (clients, servers and libraries), in terms of support SSH crypto protocols.

Today on Linux, ZFS is your only real choice for an advanced filesystem Yesterday I wrote about what I consider advanced filesystems are in general, namely filesystems with the minimum feature of checksums so you know when your data has been damaged and ideally with some ability to use redundancy to repair from damage. As far as I know, today on Linux there are only two filesystems that are advanc

Using the OS X 10.10 Hypervisor Framework: A Simple DOS Emulator Since Version 10.10 (Yosemite), OS X contains Hypervisor.framework, which provides a thin user mode abstraction of the Intel VT features. It enables apps to use virtualization without the need of a kernel extension (KEXT) – which makes them compatible with the OS X App Store guidelines. The idea is that the OS takes care of memory ma

Jobber is a utility for Unix-like systems that can run arbitrary commands, or “jobs”, according to a schedule. It is meant to be a better alternative to the classic Unix utility cron. Along with the functionality of cron, Jobber also provides: Job execution history: you can see what jobs have recently run, and whether they succeeded or failed. Sophisticated error handling: you can control whether

SSH, how does it even? A few weeks ago, I wrote ssh-chat. ssh http://t.co/E7Ilc0B0BC pic.twitter.com/CqYBR1WYO4 — Andrey 🦃 Petrov (@shazow) December 13, 2014 The idea is simple: You open your terminal and type, $ ssh chat.shazow.net Unlike many others, you might stop yourself before typing “ls” and notice — that’s no shell, it’s a chat room! While the little details sink in, it dawns on you that

『Wi-Fi 高速接続アプリ』は、自分が利用している公衆無線LANの範囲に入ったら自動で接続をしてくれるアプリです。 公衆無線LANは通常、Wi-Fiのパスワードに加えWeb認証などのセキュリティが設定されており、Wi-Fi接続→認証画面でパスワード入力の手順がいるため、即使えないというジレンマがありました。 しかし本アプリならWi-Fiの有効範囲に入れば自動でWeb認証をしてくれるのですぐに使えますよ。 使い方は、「Wi-Fi自動接続設定」から自分の利用している公衆無線LANの認証ID/PWと、どのAP（アクセスポイント）に接続するかを設定すればOKです。

The idea of "idiomatic" React hasn’t been explicitly written on, so I thought I’d offer some conventions that my team at Tune has been using during the past few months of adoption. For the sake of this article, scope will be limited to coding style in React components - not styling, componentization, or Flux strategies. Also, this is meant to be a living document - and I am sure there are better i
