Regardless of your opinions of the Go programming language, the primary implementation of Go, gc, is an incredible piece of software engineering.

Rust has been Stack Overflow’s most loved language for four years in a row, indicating that many of those who have had the opportunity to use Rust have fallen in love with it. However, the roughly 97% of survey respondents who haven’t used Rust may wonder, “What’s the deal with Rust?”

Because of the arcane syntax? Because other languages can’t do the job? Can’t you already do everything with sed and grep? This post makes some good arguments as to why awk is valuable to learn.

This could eventually bring Go-style coroutines (aka: concurrency within the code) to C++.

DNS latency is a key component to having a good online experience. And in order to minimize DNS latency, carefully picking DNS servers and anonymization relays play an important role. But the best way to minimize latency is to avoid sending useless queries to start with.

Who’d have thought, right?

I’ve mentioned TLDR pages before, but it’s worth repeating: a community effort to simplify the beloved man pages with practical examples.

I don’t usually like promoting beta releases, but since Pi-Hole is my favorite ad-blocker at home I want to give this some special attention. New features include deep CNAME inspection, per-client blocking & the move to a database instead of plain text files for the white- and blacklists.

HonSSH is designed to be used in conjunction with a high interaction honeypot. HonSSH sits between the attacker and the honey pot and creates two separate SSH connections.

From time to time you may need to remove all history from a GitHub repository, for instance right before releasing a package.

Three years ago, Uber Engineering adopted Hadoop as the storage (HDFS) and compute (YARN) infrastructure for our organization’s big data analysis.

Here’s a small little trick when using mysqldump : you don’t have to dump an entire database, you can dump individual tables too.

An SQLite database is highly resistant to corruption. If an application crash, or an operating-system crash, or even a power failure occurs in the middle of a transaction, the partially written transaction should be automatically rolled back the next time the database file is accessed. However, there are some ways to corrupt a SQLite database - here’s how!

Some good step-by-step instructions with clear explanations on running your Elasticsearch on Kubernetes. If you haven’t played with any of these technologies, I wouldn’t recommend this approach though. :-)

git recently introduced an improved and experimental sparse-checkout feature allows users to restrict their working directory to only the files they care about. This is especially useful if your git status are very slow because your repo contains millions of files.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at localhost:8000.

Most of us write our IP addresses the way we’ve been taught, a long time ago: 127.0.0.1, 10.0.2.1, … but that gets boring after a while, doesn’t it? Now you can do things like ping 127.1 or ping 0 too!
