This document discusses the architecture of large-scale websites, including using content management systems for static content, separate image servers to reduce load, improving database design and using database clusters, implementing caching with tools like Memcached, using mirrors and load balancers like DNS, LVS, and HAProxy to distribute traffic, and optimizing performance through techniques such as converting dynamic pages to static pages.
A polyglot solution uses multiple databases to perform operations and achieve results. It creates a hybrid data store combining an RDBMS and NoSQL tools for flexible and efficient data modeling. There are several approaches to implementing a polyglot solution, including using multiple "lanes" that separate data by domain into different databases, a polyglot mapper that handles multiple databases in parallel through mapping, a nested database where a primary database maps to a secondary one, or an omnipotent database that uses multiple relational and non-relational storage engines in parallel. The advantages of a polyglot solution include leveraging different databases' strengths and providing scalable, high performance query capabilities, while the disadvantages include increased complexity and imped
This document discusses the emergence of persistent memory (PM) technologies for big data applications and the challenges of using DRAM alone. It proposes a new approach of combining PM, such as NVDIMM and 3D XPoint, with flash memory and a software stack to get the low latency of memory and high capacity of storage. This could provide a single storage platform for NoSQL databases with predictable performance, easy deployment and management, and faster recovery times compared to traditional siloed memory and storage architectures.

People with depression tend to interpret events in consistently negative ways, according to cognitive theories of depression. Two influential theories are that of negative thinking and learned helplessness. Negative thinking lies at the heart of depression, with maladaptive attitudes, errors in thinking, and automatic thoughts combining to produce depressive symptoms. Research supports the role of negative thinking patterns, with depressed individuals recalling unpleasant experiences more and making more errors in logical interpretations. Automatic thoughts of worthlessness and hopelessness also contribute to depression.

Dear [Friend's Name],
I read your email about considering applying for a student exchange programme in another country. I think this is a wonderful opportunity that you should definitely pursue. There are so many benefits to participating in a programme like this.
Firstly, you would get to visit and experience life as a student in a foreign country. This is an amazing chance to be immersed in a new culture and way of life. You would learn so much just from experiencing daily life overseas as a local student.
Secondly, you would be exposed to diverse learning opportunities. The teaching and learning strategies may be different in other education systems. This variety could open your mind
The document describes the author's experiences with educational technology over time from kindergarten through college. When the author was in kindergarten in the early 1990s, they used old Macintosh computers to save work on floppy disks and view videos on VHS tapes. In high school in the early 2000s, there were a few computers available and teachers could rent laptops, while classrooms had televisions and VCRs. In college in the mid-2000s, classrooms had projectors and students submitted work online through the school portal and used flash drives. The author hopes to use technology like interactive whiteboards and student iPads in their future elementary classroom.

Simple server side cache for Express.js with Node.jsGokusen Newz
This document discusses server-side caching for web applications using Express.js and Node.js. It defines caching as storing dynamically generated data for reuse to improve performance. Caching works by storing response data in memory or on disk so subsequent identical requests can be served from cache rather than re-generating the response. The document outlines the benefits of caching like better performance, scalability and robustness. It also covers caching terminology, different caching types, and how to implement caching using file system caching or in-memory caches like Memcached and Redis.
In today’s systems , the time it takes to bring data to the end-user can be very long, especially under heavy load. An application can often increase performance by using an appropriate caching system. There are many caching level that you can use in our application today : CDN, In-Memory/Local Cache, Distributed Cache, Outut Cache, Browser Cache, Html Cache
Web caching stores copies of frequently accessed web content like images, HTML files and JavaScript in temporary caches located near users. This improves website load times by serving content directly from caches instead of the original web server. There are different types of caches including browser caches on devices, proxy caches within networks, and CDN caches globally. Effective use of caching reduces server loads and bandwidth usage while improving user experience, though it requires addressing limitations like stale content and privacy concerns.
This document summarizes different caching techniques that can be used with PHP, including caching content, database caching, and memory caching using APCU, Memcached, and Redis. It provides code examples for storing, getting, and deleting values from the cache with each technique. Specifically, it shows how to cache objects in memory and check the cache before querying a database to improve performance.

This document discusses using Windows Server AppFabric to scale the data tier of web applications. It describes the typical challenges of scaling a web application's data tier, such as databases becoming saturated and services slowing down. It then introduces Windows Server AppFabric as a solution, which provides a distributed in-memory cache that can be shared across servers and services. This allows caching data across multiple machines, reducing database load and eliminating duplicate requests. It provides examples of how AppFabric can be used to cache reference data, integrate with sessions, and support optimistic/pessimistic locking for shared resources.
Like all frameworks, Drupal comes with a performance cost, but there are many ways to minimise that cost.
This session explores different and complementary ways to improve performance, covering topics such as caching techniques, performance tuning, and Drupal configuration.
We'll touch on benchmarking before presenting the results from applying each of the performance techniques against copies of a number of real-world Drupal sites.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

4. Type of caches
• Opcode Cache : APC, eAccelerator, Wincache, Xcache
• Query Result cache : Memcache, Redis
• CDNs : Content Delivery Networks
19/12/11
5. APC
• APC : Alternative PHP Cache
• That heavily optimizes and tunes the output of the PHP bytecode compiler and stores
the final, compiled result in shared memory.
• This bytecode optimization leads to faster runtime execution since source files do not
need to be recompiled
• re-use the compiled code rather than having to retrieve the opcodes from a disk cache,
• 3x increase in page generation speed

Key Value pair
Slabs, pages, chunks
A slab class is a collection of pages divided into same sized chunk.
Each slab class has one or more pages, The page is of a predefined size (default
1MB). So, depending on the chunk size each page has a certain number of chunks
and some space left over wasted
• LRU is rescue : When memory gets full, so no pages can be created, the LRU (Least
Recently Used) algorithm kicks in.

9. CDNs
• A content delivery network or content distribution network (CDN)
• large distributed system of servers deployed in multiple data centers
across the Internet
• The goal of a CDN is to serve content to end-users with high availability
and high performance.
• CDN serves : static files like js, css, images, text files
