Essential Linux Kernel Security Settings Below are some important security-related kernel settings for Linux. These can be configured in /etc/sysctl.conf or by adding files to /etc/sysctl.d/ . IPv4 Networking Settings TCP SYN Cookie Protection Protects against SYN flood attacks by enabling TCP SYN cookies. This kicks in only when net.ipv4.tcp_max_syn_backlog is reached: net.ipv4.tcp_syncookies = 1 Time-Wait Assassination Protection Drops RST packets for sockets in the TIME-WAIT state to prevent TCP time-wait assassination hazards. Although not widely supported outside Linux, this conforms to RFC standards: net.ipv4.tcp_rfc1337 = 1 TCP Timestamps Pros: Protects against sequence number wrapping at gigabit speeds and provides round-trip time calculations. Cons: Adds overhead and allows uptime detection by tools like Nmap. Enable for gigabit speeds: net.ipv4.tcp_timestamps = 0 #net.ipv4.tcp_timestamps = 1 Source Address Verification Helps prevent spoofing...

A Human-Friendly Git Workflow Managing Git can be simpler and more intuitive with a streamlined workflow. Below is a guide to using a human-friendly Git toolkit to make common tasks easier and faster: Key Commands Switch branches: git switch <branch> Quickly switch to another branch. Any unstaged changes are automatically stashed and restored afterward. Synchronize branches: git sync Brings the current branch up to date by automatically merging or rebasing changes from the remote repository. Handles stashing and unstashing as needed. Publish a branch: git publish <branch> Push your branch to the remote server, making it available to others. Unpublish a branch: git unpublish <branch> Remove a branch from the remote server. Harvest changes: git harvest <branch> Automatically merge or rebase commits from another branch into the current branch. Create a new branch: git sprout <branch> Start a new branch based on your current bra...

F# - Efficiently Converting Sequences of Characters to Strings When working with sequences of characters in F#, there are scenarios where you need to efficiently convert them into a string. This is a common task when handling data transformations or working with input/output operations. Below, I’ll walk you through two useful F# extensions for converting sequences of characters into strings, with a special focus on efficiency and flexibility. Convert a Sequence of Characters to a String : F# provides a straightforward way to convert any sequence of characters ( seq<char> ) into a string. Using the Seq.toArray function, we convert the sequence into an array of characters, and then pass it to the String constructor: type System.String with static member ofSeq (s: seq<char>) = new String(s |> Seq.toArray) Why this works : Sequences in F# are lazily evaluated, and converting them to an array allows us to materialize the sequence into a fixed-size, contiguous me...

Welcome to Software 4 Better World Hi there 😀 I’m so glad you’ve found your way here. This little corner of the internet is where I pour my passion for technology, coding, and making a difference.
