#introduction

Ever since I was 7 years old, I've been interested in computers, the Internet, and more recently, cybersecurity and social engineering.

I strive to become an excellent cybersecurity engineer. I'm always eager to learn and love meeting new people with similar interests. Feel free to drop me a DM!

For more information, please check out my personal blog: https://L1Cafe.blog.

Friendly reminder: #BOINC is a great project to contribute your otherwise idle computing power.

https://boinc.berkeley.edu

You can set complex scheduling options, either by time of day, battery level, non-BOINC CPU usage, mouse and keyboard activity and so on. This way, it won't take up all your resources when you're compiling or playing videogames.

You can also configure it to only take a percentage of the CPU, a specific core count, or only allow it to run in bursts.

#facebook is embedding tracking data inside photos you download.

I noticed a structural abnormality when looking at a hex dump of an image file from an unknown origin only to discover it contained what I now understand is an IPTC special instruction. Shocking level of tracking..

Honestly I ran out of ideas for my blog, and I don't know what to post. I could keep posting CTFs but it seems kinda unappealing to me... Suggestions?

Hello @john_tedesco. Thanks for the follow. I guess you found me through some Mastodon mass-following tool while you were searching for people in Information Security / Hacking.

Reading your contact page https://johntedesco.net/blog/contact/, have you considered...?:

1 - Signal. End to end encrypted, FOSS and only requires a phone number.
2 - Threema. Audited, Swiss-made, closed source, single payment application.
3 - Keybase/traditional PGP/GPG.

Let me know if you need help setting any of those up.

In all honesty I knew I shouldn't trust closed source software for my notes. Especially not Microsoft-made. But it felt really convenient for the time. Until problems started appearing, exactly when I needed my notes the most. This is unacceptable for a multinational multibillionaire enterprise, with so many incredibly talented engineers.

But you disappointed me again when I tried to move note sections to a different notebook from my iPad. Then, your app crashed and my notes were left in an inconsistent state. Some notes appeared on the new notebook, but others showed as "not synchronised yet", and every time I tried to open the iPad app again, it crashed within seconds. So you lost my university notes.

I'm going back to regular file sync. Hello @nextcloud, good bye Microsoft.

OneNote, I trusted you. But you failed me. You failed me once when I accidentally surpassed the storage limit, creating a mess and making me pay to temporarily lift the storage size. I had to manually recover the notes from an older OneNote version because the newer ones don't have an "export to PDF" or even to proprietary OneNote format. I decided to give you a second opportunity.

The space race is on again! ❤️ 🔥

New post! https://l1cafe.blog/2019/06/30/automating-proxmox-with-ansible

It's about automating #Proxmox through #Ansible. Great for Ansible beginners, too.

You can see what kind of spam you expose yourself to if you allow comments without any kind of bot verification mechanism here: https://github.com/L1Cafe/L1Cafe.github.io/pulls?q=is%3Apr+is%3Aclosed

I have decided to disable comments on my blog https://L1Cafe.blog because, after more than 150 comments received, none of them had actual content, and were merely spam and black SEO. Ads about amoxicilin and questionable drug sellers.

I also do this because I refuse to use Google reCaptcha, as I think it poses a threat to individual privacy.

As always, I'm open for suggestions.

Nice initiative. I hope all companies join some day. https://noageismintech.com/ 😄

This is extremely interesting. I want to read your thoughts.
