Nmap has been my favorite hacking tool for years. Its accuracy is unchallenged and it boasts hundreds of scripts that make it vital in every pentest engagement. Lately, I’ve been working more on the ICS space, developing a OPC UA vulnerability scanner. To my dismay, I noticed that Nmap does not recognize OPC UA services. This makes black box security testing of this dominating ICS protocol tricky, as OPC UA server vendors are known to use n..

We walked anti-clockwise from Southwold, along the edge of the sports grounds, and then through the sand dunes. There were quite a few people about, and lots of dogs. At the mouth of the River Blyth you can see the ferry crossing to Walberswick. It was then easy going on the sand back to Southwold, with even more people and dogs, since it turned out to be a remarkably warm and sunny day for March.

For those who have found their meaning, their place in the world, and what they feel they want to live for, death is just one part - inevitable, but not frightening - of a good life—a death all woven with life, which has the smile and soft touch of a newfound embrace. I wish myself, anyone, such a death. – Benedetta Tobagi, La Resistenza delle donne

As most modern GNU+Linux distro users already know, you get a lot of tools included for free! Many of these may clutter up your $PATH and make bash tab completion more difficult than it has to be. Here’s a way to improve this! A mess : Here’s what I see when I tab-complete cd

I just came across this tweet by Aaron Levie : The best founders I know — no matter their company’s scale — thrive on doing customer support directly. There’s literally no better way to understand the pulse of your customer base, what features to build next, or where systems are breaking down. It’s always upside. It profoundly resonates with me. For context, we’ve been a small company in the market since 1991, making us quite the ra..

There are many discussions about the 30% fee Apple charges for the App Store. This fee is significant, and its benefits are not immediately clear. The complaints primarily come from large companies like Epic Games, Spotify, and Netflix, which have the resources to challenge Apple. However, what about indie developers? What do we receive in return for this 30% fee, and are we genuinely upset about it? In practice, when I price my applicati..

This post is a work in progress. I'll update it as I go, and I might be missing very obvious things (or haven't gotten around to it yet). Feel free to shoot me an email if you want to make a comment. A few months ago I was helping with a Rust-based Llama2 inference project and learned a few things about optimizing CPU SIMD code. One thing I couldn't shake is that codegen in Rust is still pretty bad at the moment, at least for neural....

I’ve blogged about generic ways of getting top 1 or top n per category queries before on this blog.

This has always been true, but it begs repeating: Every docstring should provide additional information about the thing that it is documenting, which is not obvious from the thing’s name and its type information. And the corollary: If an LLM could generate the same docstring for you , based on the name and type information alone, then the docstring is not adding any value .

I’ve had some minor aches and injuries over the past few months. Nothing terrible. More like the Henny Youngmann joke . No long or fast running for a little while longer. Limited bench pressing and squats. If it hurts, don’t do it. That kind of thing. I found myself with time to fill. A specific kind of time. I needed something I could do on my own that requires focus. I’ve started writing more. For me, writing also means designing, co....

Hamel dives deep into how LLM frameworks like langchain , instructor , and guidance perform tasks like formatting the response in a valid JSON output. He intercepts the API calls from these Python libraries to shed some light on how many API calls (to OpenAI’s GPT services) they make and what prompt they use. I’ve always been skeptic of the usefulness of many of the LLM “wrapper” libraries, specially for larger and more serious proje..

I just had a very special delivery that I was looking forward to for a few days now. I received my Canon AE-1 Program from 1981. I’m drawn towards the simplicity, haptic, connectedness to the past and less arbitrariness of digital photography or life in general. Just a few months ago I also bought a new notebook, the Midori traveller’s notebook. Although I’ve been journaling on paper for a while now, I replaced digital notes with this as ....
