Basics of boot-loader
A bootloader loads an operating system after hardware tests. It begins by initializing hardware and loading the BIOS. The BIOS then loads the master boot record from the disk, which loads secondary bootloaders. These load the operating system by accessing memory in both real and protected modes. The boot process involves loading kernel files and an initial ramdisk to start processes and mount the full filesystem.

Javacardtech
Java Card technology allows Java programming on smart cards by implementing a subset of the Java programming language. A Java Card application consists of an on-card applet and supporting off-card systems. Communication with the applet occurs through Application Protocol Data Units (APDUs) or Java Card Remote Method Invocation (RMI). The Java Card runtime environment provides APIs for smart card functions like secure element access while imposing limitations due to hardware constraints such as no threads or doubles.
Study of Java Card and its Application
Sun Microsystems defined a set of specifications for a subset of Java technology to create applications for them, Java Card applets. A device that supports these specifications is referred to as a Java Card platform. On a Java Card platform, multiple applications from different vendors can coexist securely. The Java Card platform is the tiniest of Java targeted for embedded devices. It is an open, interoperable platform for smart cards and secure tokens. The technology is widely used in SIM cards (it's used in GSM mobile phones) and ATM cards. Java Card gives users the ability to program a device and make it application specific and lets smart card developers use a common card platform. Smart cards, unlike magnetic stripe cards, can carry all necessary functions and information on the card; therefore, they do not require access to remote databases at the time of the transaction.

Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Hand Rolled Applicative User Validation Code Kata
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
