I blog about CTFs and system administration. Sometimes a bit of reverse engineering as well.

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.
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.
Contribute today!

"You can't change your passwords because you're bad at managing them" is as good of a justification as "you can't paste passwords into this password field because storing them in a password manager is bad practice", and dnswl.org administrators should know better than this.

There I was thinking that using different SSH keys for each server was sufficient protection. Who thought that sending all of them to any server you try to connect to was a good idea?

OpenSSH finally adds support for U2F keys! This is awesome! https://www.zdnet.com/article/openssh-adds-support-for-fidou2f-security-keys

Waterfox, a fork of Firefox, has been sold to System1, an ad/online marketing company. You probably want to watch out what happens to Waterfox from there on, if you ever used it. #linux #firefox #waterfox https://www.waterfox.net/blog/waterfox-has-joined-system1
I find the sweet spot to be at deferring feature updates for 60 days, and security updates for 8 (just enough to make sure a week passes before any issues are found, just in case).
For example, I just received update 1909, which was released starting in November 2019: https://www.howtogeek.com/437112/whats-new-in-windows-10s-19h2-update-arriving-fall-2019/ , more than enough time to fix its rough edges.
Since it is well-known that Microsoft Windows 10 updates tend to be buggy on the day of release, it is possible to defer upgrades for a given period of time. This means you won't get the latest and greatest features, but if you're a content producer, a professional who relies on their computer, or just a heavy gamer, you may appreciate the improved stability.
Note that this requires Windows 10 Pro. If you run Home, I recommend you upgrade to Pro.

Mastodon is not, and possibly never can be, the platform which will break the Twitter/Facebook/Youtube monopoly.
It is a Twitter-clone with perhaps something more of a social dimension.
But to really take on Big Tech what the Fediverse needs is a viable alternative to Facebook and neither Mastodon nor Pleroma fulfills that function.
Mastodon/Pleroma are too ephemeral. Real connections can be made, but they are the exception that proves the rule.
The fediverse must evolve.
Just realised I misconfigured this Mastodon account. I had the setting to reject unknown DMs enabled.
If you DM'd me in the past and I didn't reply, I'm sorry. Please, feel free to send me a new DM again!

Chrome will block video ads that “people find to be particularly disruptive". Conveniently enough, YouTube ads are not so disruptive, so they most probably won't be touched.

Does anyone have an invitation for https://lobste.rs that they'd like to share with me? Thanks!

From HN discussion - "This is why I use ad blockers and a pi-hole server" (https://news.ycombinator.com/item?id=22124929)
This is GDPR in action. Wow.

Have you implemented the usual SSH hardening measures?
* Move SSH port to something high
* Use fail2ban or similar
* Disable root login
* Use Public/Private key auth instead of passwords
* Make sure the passwords you do use are secure and not re-used somewhere else
* Alert on positive SSH logins (e.g. via mail)

Just set up my Tor relay https://metrics.torproject.org/rs.html#details/8BC3BBF901101500F58FEB9DA401B6725FB78AA6
It's reachable at IP 54.38.239.109:9922 with fingerprint 8BC3BBF901101500F58FEB9DA401B6725FB78AA6. Enjoy!

If you are interested in leaving #Medium (and you should!), there's
a nice script to migrate to Jekyll
I am a Computer Science student on my last year of university. I am looking for someone friendly who wishes to help me with my final thesis: https://github.com/L1Cafe/XYZ, it's a programming language.
It doesn't have to be a single person to help me, and it doesn't have to be full-time help. Suggestions are always appreciated, but it would just be great to have someone friendly to chat with who has experience with compilers and parsers.
If you don't, maybe you can boost this? Thx!
