Spooling in Operating System

The Crazy Programmer

Similar is the concept of spooling which is used in our Operating Systems. To understand this concept thoroughly, we will first take a look at the basic operations that take place in our operating systems and subsequently, derive how the mechanism of spooling gives an edge to these operations.

What is Multiprogramming Operating System

The Crazy Programmer

In the present computer, many parallel application processes are required to execute to run the system. This is now the function of the OS to control & control all the processes efficiently and effectively which is conversely the paramount function of the operating system.

Systems Observability

Dzone - DevOps

According to Wikipedia: "Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. In control theory, the observability and controllability of a linear system are mathematical duals.". What Is Observability?

Difference between Firmware and Operating System (OS)

The Crazy Programmer

In this article, we will understand the difference between firmware and operating system. Operating systems are the complete software that coordinates with the other software applications and the hardware components of the devices. What is Operating System? Operating system (OS).

Difference between FAT and NTFS File System

Schema Evolution Patterns

Speaker: Alex Rasmussen, CEO, Bits on Disk

If you want to make your development team squirm, ask them about database schema changes or API versioning. Most development teams struggle with changing database schemas and updating API versions without breaking existing code. Alex Rasmussen is an expert in helping teams through these struggles. His talk will examine database schema changes and API versioning as two instances of schema evolution: how your systems respond when the structure of your structured data changes.

Different Types of Embedded Systems

The Crazy Programmer

Embedded systems are the collection of the hardware and software where the software has been embedded into the hardware components. Therefore many people are showing their interest in using embedded systems for their professional use. What is an Embedded System?

Distributed Systems Pattern: State Watch

Martin Fowler

Clients are interested in changes to the specific values on the server. It's difficult for clients to structure their logic if they need to poll the server continuously to look for changes. If clients open too many connections to the server for watching changes, it can overwhelm the server. more….

Distributed Systems Pattern: Quorum

Martin Fowler

Distributed systems may get partitioned, when the nodes in the cluster no longer talk to all the others. Unmesh explains that, because of this, we need a quorum of nodes within a partition to accept a change.

Distributed Systems Pattern: Idempotent Receiver

Martin Fowler

Clients send requests to servers but might not get a response. It's impossible for clients to know if the response was lost or the server crashed before processing the request. To make sure that the request is processed, the client has to re-send the request.

Trusted AI 102: A Guide to Building Fair and Unbiased AI Systems

The risk of bias in artificial intelligence (AI) has been the source of concern and debate. High-profile examples demonstrate the reality that AI is not a default “neutral” technology and can come to reflect or exacerbate bias encoded in human data.

Distributed Systems Pattern: Consistent Core

Martin Fowler

Unmesh has a few more of his Patterns of Distributed Systems ready to share with the world. In this one he looks at the problem of a large cluster, one that is too large to effectively maintain strong consistency, yet needs to maintain some data in a strongly consistent way.

Distributed Systems Pattern: Segmented Log

Martin Fowler

A single log file can grow and become a performance bottleneck while its read at the startup. Older logs are cleaned up periodically and doing cleanup operations on a single huge file is difficult to implement. A Segmented Log splits the logfile into smaller files.

System 246

Distributed Systems Pattern: Lease

Martin Fowler

Cluster nodes need exclusive access to certain resources. But nodes can crash; they can be temporarily disconnected or experiencing a process pause. Under these error scenarios, they should not keep the access to a resource indefinitely. more…. skip-home-page

Thrashing in Operating System (OS)

The Crazy Programmer

When a program need space larger than RAM or it need space when RAM is full, Operating System will try to allocate space from secondary memory and behaves like it has that much amount of memory by serving to that program. Whenever a page fault happens, operating system will try to fetch that page from secondary memory and try to swap it with one of the page in RAM.
