There is a little trick I just found about, which I think can be very useful when you split tasks across different notebooks. Jupyter notebooks keep gaining popularity and use cases, the rapid growth of the tooling ecosystem around it is just one proof (for example voilà or panel ). Most people choose Jupyter when publishing a course or tutorial on Github and that’s great, but when there are a lot of notebooks it can become messy.

Whenever I’ve been promoted or moved into a management position, I reach for this book which I learned about after reading this post on how your first three months are so important for setting the right tone with your manager and the role you are signing up for.

The growth of open source alongside the lagging security standards has led many regulatory bodies and industry watchdogs to move toward stricter and clearer rules around how to protect applications that include open source code.

Hello! I thought it would be fun to write a post aimed towards business leaders making technology decisions for their organizations. There is a lot of hype in our field and little truth behind the hype. Like most things I write about, this started from an idea I had on Twitter: has anyone ever done technical breakdowns of these products in Gartner reports that are actually just trash, is this something you'd read..? — jessie frazell....

A little over a year ago, I moved to Fort Gordon for the Cyber Basic Officer Leaders Course. I saw one of my former classmates in the gym this morning, lounging on a bench press near two of his Soldiers. He once said that he did not have hours to spend in the gym every day, and that he had better things to do with his time. Permalink.

Bye Whatsapp A while ago I decided to move away from Whatsapp and Telegram in favor of Matrix, mostly to improve my privacy and get more control over my own data - yes Whatsapp, I’m looking at your limited backup options. But enough about the idealistic tech vision and more about tech itself. To get the most out of Matrix it is best to deploy an instance for yourself. It’s quite an involved process, however luckily there’s an Ansible playbo..

Developing cross-platform applications presents a major challenge:, how to ensure that every commit does not break some combinations of operating systems and CPU architectures. Fortunately, thanks an array of online services and open-source tools, this challenge becomes easier to tackle.

TL;DR - With such an overwhelming response to the original post , I have turned this into a KickStarter in an attempt to make this work. You can check it out here .

In my last post, I looked into the infrastructure of mimalloc, to be frank. A few details on how it is actually hooking the system allocator when used, mostly. I’m still using what is effectively a random scatter/gather approach to the codebase. Mostly because it is small. I’m trying to… grok it would be the best term, I guess. I’m going over the code because it also give me a good idea about practices in what seems to be a damn good C co....

Tom Smith over at DZone, one of a handful of websites I read every day , just finished a great three-part series on common cybersecurity shortfalls. He highlights the importance of basic countermeasures, like encryption and patching, all the way up to complex topics like attack vectors. I recommend all three: part 1 , part 2 , and part 3 .

After nearly a year coding in Python (although not consistently), I started trying code formatters and discovered they were more useful than I thought. Here are some reason why. First, I must admit these tips may be biased by the fact I use Jupyter Notebooks quite a lot. I think they are an incredible tool for learning although they may also instill some bad coding habits. Before talking about black lets go through the step to insta..

Previously in emulator basics: 1. a stack and register machine In this post we'll extend x86e to support the exit and write Linux system calls, or syscalls. A syscall is a function handled by the kernel that allows the process to interact with data outside of its memory. The SYSCALL instruction takes arguments in the same order that the regular CALL instruction does. But SYSCALL additionally requires the RAX register to contain ....
