1) Inserting and querying documents using operators like $lt and $in
2) Returning documents through cursors and using projections to select attributes
3) Updating documents using operators like $push, $inc, and $addToSet along with bucketing and pre-aggregated reports
It also covers durability options like acknowledged writes and waiting for replication.
XPDDS17: Shared Virtual Memory Virtualization Implementation on Xen - Yi Liu,...The Linux Foundation
Shared Virtual Memory (SVM) is a VT-d feature that allows sharing application address space with the I/O device. The feature works with the PCI sig Process Address Space ID (PASID). With SVM, programmer gets a consistent view of memory across host application and device, avoids pining or copying overheads. We have been working on supporting SVM in Xen to enable SVM usage in guest if a SVM capable device is assigned. e.g. assign IGD to a guest, applications like OpenCL would benefit if SVM is supported in guest. SVM virtualization requires exposing a virtual VT-d to guest. In this discussion, Yi would update the latest SVM virtualization implementation and foresee the future work about supporting SVM and IOVA a single virtual VT-d.

This model makes our customers the owner of the entire BSP source code along with the solution IP rights.
In this presentation, Yasunori Goto and Qi fuli will talk about basis of NVDIMM, the issues of RAS of Non Volatile DIMM(NVDIMM), and what feature is made and is developing for it.
NVDIMM is expected as new age device recently. Though a cpu can read/write the NVDIMM directly like RAM, the data of NVDIMM remains after power down or reboot. So, on memory database will be one of the good example of usecase of NVDIMM.
Since many people have made great effort for Linux, NVDIMM drivers, filesystems,management command, and many libraries has been well developed for a few years,
However, Yasunori Goto found some issues about RAS(Reliabivity, Availability, and Serviceability) feature of NVDIMM, because characteristic of the NVDIMM is likely mixture of Storage and RAM. For example, NVDIMM does not have hotplug feature because it is inserted at DIMM slot like RAM, but its data must be back-upped/restored like storage.

View this presentation to understand:
What a storage engine is
How to pick a storage engine
How to configure a storage engine and a replica set
Back to Basics Webinar 3: Schema Design Thinking in DocumentsMongoDB
This is the third webinar of a Back to Basics series that will introduce you to the MongoDB database. This webinar will explain the architecture of document databases.
Webinar: Back to Basics: Thinking in DocumentsMongoDB
New applications, users and inputs demand new types of data, like unstructured, semi-structured and polymorphic data. Adopting MongoDB means adopting to a new, document-based data model.
While most developers have internalized the rules of thumb for designing schemas for relational databases, these rules don't apply to MongoDB. Documents can represent rich data structures, providing lots of viable alternatives to the standard, normalized, relational model. In addition, MongoDB has several unique features, such as atomic updates and indexed array keys, that greatly influence the kinds of schemas that make sense.
In this session, Buzz Moschetti explores how you can take advantage of MongoDB's document model to build modern applications.
Speaker: Daniel Coupal
At this point, you may be familiar with the design of MongoDB databases and collections – but what are the frequent patterns you may have to model?
This presentation will add knowledge of how to represent common relationships (1-1, 1-N, N-N) in MongoDB. Going further than relationships, this presentation identifies a set of common patterns, in a similar way to what the Gang of Four did for Object Oriented Design. Finally, this presentation will guide you through the steps of modeling those patterns in MongoDB collections.
In this session, you will learn about:
How to create the appropriate MongoDB collections for some of the patterns discussed.
Differences in relationships vs. the relational database world, and how those differences translate to MongoDB collections.
Common patterns in developing applications with MongoDB, plus a specific vocabulary with which to refer to them.

MongoDB Introduction talk at Dr Dobbs Conference, MongoDB Evenings at Bangalo...Prasoon Kumar
MongoDB is a leading nosql database. It is horizonatally scalable, document datastore. In this introduction given at Dr Dobbs Conference, Bangalore and Pune in April 2014, I show schema design with an example blog application and Python code snippets. I delivered the same in the maiden MongoDB Evening event at Delhi and Gurgaon in May 2014.
When constructing a data model for your MongoDB collection for CMS, there are various options you can choose from, each of which has its strengths and weaknesses. The three basic patterns are:
1.Store each comment in its own document.
2.Embed all comments in the “parent” document.
3.A hybrid design, stores comments separately from the “parent,” but aggregates comments into a small number of documents, where each contains many comments.
Code sample and wiki documentation is available on https://github.com/prasoonk/mycms_mongodb/wiki.
Media owners are turning to MongoDB to drive social interaction with their published content. The way customers consume information has changed and passive communication is no longer enough. They want to comment, share and engage with publishers and their community through a range of media types and via multiple channels whenever and wherever they are. There are serious challenges with taking this semi-structured and unstructured data and making it work in a traditional relational database. This webinar looks at how MongoDB’s schemaless design and document orientation gives organisation’s like the Guardian the flexibility to aggregate social content and scale out.
MongoDB, PHP and the cloud - php cloud summit 2011Steven Francia
An introduction to using MongoDB with PHP.
Walking through the basics of schema design, connecting to a DB, performing CRUD operations and queries in PHP.
MongoDB runs great in the cloud, but there are some things you should know. In this session we'll explore scaling and performance characteristics of running Mongo in the cloud as well as best practices for running on platforms like Amazon EC2.
Webinar: General Technical Overview of MongoDB for Dev TeamsMongoDB
In this talk we will focus on several of the reasons why developers have come to love the richness, flexibility, and ease of use that MongoDB provides. First we will give a brief introduction of MongoDB, comparing and contrasting it to the traditional relational database. Next, we’ll give an overview of the APIs and tools that are part of the MongoDB ecosystem. Then we’ll look at how MongoDB CRUD (Create, Read, Update, Delete) operations work, and also explore query, update, and projection operators. Finally, we will discuss MongoDB indexes and look at some examples of how indexes are used.
As your data grows, the need to establish proper indexes becomes critical to performance. MongoDB supports a wide range of indexing options to enable fast querying of your data, but what are the right strategies for your application?
In this talk we’ll cover how indexing works, the various indexing options, and use cases where each can be useful. We'll dive into common pitfalls using real-world examples to ensure that you're ready for scale.
This talk will introduce the philosophy and features of the open source, NoSQL MongoDB. We’ll discuss the benefits of the document-based data model that MongoDB offers by walking through how one can build a simple app to store books. We’ll cover inserting, updating, and querying the database of books.
Relational databases are central to web applications, but they have also been the primary source of pain when it comes to scale and performance. Recently, non-relational databases (also referred to as NoSQL) have arrived on the scene. This session explains not only what MongoDB is and how it works, but when and how to gain the most benefit.

MongoDB .local San Francisco 2020: Powering the new age data demands [Infosys]MongoDB
Our clients have unique use cases and data patterns that mandate the choice of a particular strategy. To implement these strategies, it is mandatory that we unlearn a lot of relational concepts while designing and rapidly developing efficient applications on NoSQL. In this session, we will talk about some of our client use cases, the strategies we have adopted, and the features of MongoDB that assisted in implementing these strategies.
MongoDB .local San Francisco 2020: Using Client Side Encryption in MongoDB 4.2MongoDB
Encryption is not a new concept to MongoDB. Encryption may occur in-transit (with TLS) and at-rest (with the encrypted storage engine). But MongoDB 4.2 introduces support for Client Side Encryption, ensuring the most sensitive data is encrypted before ever leaving the client application. Even full access to your MongoDB servers is not enough to decrypt this data. And better yet, Client Side Encryption can be enabled at the "flick of a switch".
This session covers using Client Side Encryption in your applications. This includes the necessary setup, how to encrypt data without sacrificing queryability, and what trade-offs to expect.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Editor's Notes
Not really fire and forget.
This return arrow is to confirm that the network successfully transferred the packet(s) of data.
This confirms that the TCP ACK response was received.
Presenter should mention:
Default is w:1
w:majority is what most people should use for durability.
Majority is a special token here signifying more than half of the nodes in the set have acknowledged the write.
