The latest blog posts to take off on Hacker News. 255 posts.
This post is a basic introduction to running HTTPS servers and clients in Go using TLS. It assumes some familiarity with public-key crypto. Feel free to check out my earlier posts about RSA and the Diffie-Hellman Key Exchange ; TLS uses the elliptic-curve version of Diffie-Hellman. I won't be covering how the protocol…
In March, I got an email from SpaceX saying Starlink was available at my address, and I could pre-order. I paid $500 for the equipment, plus $25 for a Volcano Roof Mount, and $99 for the first month of service, and a few weeks later, I got the kit you see in the image above. I was a little too excited about getting…
Over the last few months I have been on and off digging into the history of early PC networking products, especially Ethernet-based ones. In that context, it is impossible to miss the classic NE2000 adapter with all its offshoots and clones. Especially in the Linux community, the NE2000 seems to have had rather bad…

I have said before that I believe that teaching modern students the OSI model as an approach to networking is a fundamental mistake that makes the concepts less clear rather than more. The major reason for this is simple: the OSI model was prescriptive of a specific network stack designed alongside it, and that…
Months ago I noticed something strange in the Little Snitch Network Monitor: Safari was still connecting to web sites after every window had been closed. At the time, I thought this was just a Safari bug. I brought the issue to the attention of some Safari engineers, who I had hoped would look into it. Since then…

Consumer Routers are not secure
SMS text messages were already the weakest link securing just about anything online, mainly because there are tens of thousands of employees at mobile stores who can be tricked or bribed into swapping control over a mobile phone number to someone else. Now we’re learning about an entire ecosystem of companies that…
Purism makes premium phones, laptops, mini PCs and servers running free software on PureOS. Purism products respect people's privacy and freedom while protecting their security.
Slack has a global customer base, with millions of simultaneously connected users at peak times. Most of the communication between users involves sending lots of tiny messages to each other. For much of Slack’s history, we’ve used HAProxy as a load balancer for all incoming traffic. Today, we’ll talk about problems we…
By now most infosec professionals are aware of various ways SMS text messaging can be hijacked. For example so-called “SIM Swap” attacks…
Google's gRPC is an RPC system that supports many languages, and is relatively widely used. I think its popularity is due to being used for parts of Docker and Kubernetes. I think gRPC is mostly fine, but it is surprisingly easy to screw up by misconfiguring it. Part of that is because RPC systems are challenging to…
Here's what we've learnt about networks and the routers that interconnect them in the last 50 years.
Cache strategies that don't trade-off correctness for speed
Earlier this month, I came back around to seriously considering an attempt at bitsquatting. While the prior link goes into great depth on the topic, I will attempt to give a very high level overview here: If this sort of thing interests you: I tend to do stuff like this weekly. Give me a follow @_mattata

We’ve launched a brand new version of Element, called Element Home!
Ping is one of the fundamental pillars of networking. It’s simple, universally supported, and is normally one of the few things that is shipped with all network stacks.
Shall I migrate to Signal, Threema or Telegram? No, because they all have — WhatsApp included — the same problem: They are walled gardens. Imagine a world where for each mail recipient using a separate domain, I would need separate mail client? Or in other words: Gmail users can only communicate with Gmail users…
