Badge Challenge 3

Original Post During each in-person Hack The Box meetup I have a small badge challenge that will give the first solver of the challenge a price. at the meetup of March 2023 there will be a very nice little challenge to be done as well, a beautiful NOVI hoodie. You can already download the password protected zip archive. The password will be shared during the meetup opening words. The zip archive (sha1: 28e84243c79caefce06f62ba2c5d930de37a3439) Good luck. Afterwards I will post a walkthrough of the challenge on this site. Badge Life is hard :) ...

Deployment Anxiety

Let me tell you how it was to ship a product out to half a million people back in 1999. But before I do that, let me tell you why. Today I talked to one of my students and he mentioned that he was very nervous about a change he was making. He was afraid it would break things and that he would spend the afternoon working through his CI/CD pipeline to resolve issues. ...

Cleaning up after LSP-mode

I use lsp-mode quite extensively. I switched from eglot when I started using LSP more. The beautify of lsp-mode is that it will automatically install language servers as you need them. It also integrates excellently with dap-mode to enable debugging sessions. So, I switched to it, turned off all the information overload and I am quite happy. One thing I do extensively is that I use LaTeX to make my slides for college class slides and class assignments. That means I have hundreds of directories with presentations, assignments and other documents. Each time I enter a directory for a class it will spawn an LSP session for that set of LaTeX files. ...

Should we pay for open source?

As the world is processing the Twitter deal the open source project Mastodon is gaining a lot of traction. The instance that I am on, fosstodon, is run by a small team and is fully funded by donations. Now this may sound somewhat strange; as the twitterverse is blowing up about $8/month for a blue checkmark I would argue that the $8 is better spent supporting open source projects. As developers, security people, and users we rely on a lot of free time and effort from open source contributors. ...

22 years of Emacs

Where to begin… I just watched David Wilson’s talk called M-x forever - why Emacs will outlast text editor trends. He gave this talk at EmacsConf 2021 which is a conference dedicated to Emacs. The talk made me reflect on my use of Emacs over the last years and then I realized that this year will mark 22 years that Emacs and I have been together. This (probably too long) article reflects on those years and dives into my use of Emacs. ...

Hack The Box Ambassador

For the last 18 months I have organized the dutch Hack The Box meetups. Due to COVID-19 they have all been as a digital meetup, but not less entertaining though. During my time organizing the meetups the Hack The Box organization supports me in various ways; they give me stuff to hand out such as swag or VIP memberships, they help organize speakers for events when we don’t have one ourselves and they provide me with Hack The Box goodies every once in a while. ...
