4/26 takeaways

Today on LeetCode, I tackled a problem related to Double Heaps. Heaps are excellent for inserting elements and for retrieving the largest or smallest number. Insertion and deletion operations run in O(log n) time, while retrieving the largest or smallest number can be done in O(1) time.

I used TryHackMe alongside Metasploit for scanning, enumerating, and exploiting, which proved to be very useful at every stage of penetration testing. I also used Hydra for a brute force attack on passwords. I really like the way it displays on the terminal—it feels like I'm literally hacking! Additionally, I learned a bit about SQL security. For instance, when a table contains crucial information such as usernames and hashed passwords, tools like Metasploit and John the Ripper can be used to unhash the data.

For aufuguse, today was my second performance. My friends and co-workers came to see it, and after my performance, I received some valuable feedback from a co-worker. There are a couple of things I need to improve, which I plan to resolve by tomorrow:

1. Conserve some energy

2. Move left and right to ensure everyone can feel the wind
