During the past year our team is building Bitwhichmakes it simpler to build software using components. As part of our work, we develop ML and NLP algorithms to better understand how code is written, organized and used.
In last couple of years, we have observed evolution of several message brokers and queuing services which are all fast, reliable and scalable. While the list is long, in this blog, I will limit the discussion to SQS, Kinesis and Kafka. Simple Queuing Service (SQS) is a fully managed and scalable queuing service on AWS. Kinesis is another service offered by AWS that makes it easy to load and analyze streaming data and also provides the ability to build custom streaming data applications for special requirements. Apache Kafka is a fast, scalable, durable, and fault-tolerant publish-subscribe messaging system which is often used in place of traditional message brokers like JMS and AMQP because of its characteristics like higher throughput, reliability and replication.
While making decisions about which messaging system is right for you, it is important to understand not only the technical differences but also the implications of operational costs both in terms of running them at scale as well as monitoring them. In this blog, I will touch upon our experiences and learning at OpsClarity, based on our evaluation of messaging systems and our migration from SQS to Kafka.
In this guide I will show you how to use Firebase, React, and Ant Design as building blocks to build functional, high-fidelity web applications. To illustrate this, we’ll go through an example of building a todo list app.
Using the above approach is productive – especially if you have good boilerplate to get you started – but what if you want to build something quickly with nearly zero setup time? Sometimes a mockup doesn’t convey enough information to a client; sometimes you want to build out an MVP super fast for a new product.
You can enable continuous backups with a single click in the AWS Management Console, a simple API call, or with the AWS Command Line Interface (CLI). DynamoDB can back up your data with per-second granularity and restore to any single second from the time PITR was enabled up to the prior 35 days. We built this feature to protect against accidental writes or deletes. If a developer runs a script against production instead of staging or if someone fat-fingers a DeleteItem call, PITR has you covered. We also built it for the scenarios you can’t normally predict. You can still keep your on-demand backups for as long as needed for archival purposes but PITR works as additional insurance against accidental loss of data. Let’s see how this works.
Deep neural networks are composed of many individual neurons, which combine in complex and counterintuitive ways to solve a wide range of challenging tasks. This complexity grants neural networks their power but also earns them their reputation as confusing and opaque black boxes.
Understanding how deep neural networks function is critical for explaining their decisions and enabling us to build more powerful systems. For instance, imagine the difficulty of trying to build a clock without understanding how individual gears fit together. One approach to understanding neural networks, both in neuroscience and deep learning, is to investigate the role of individual neurons, especially those which are easily interpretable.
Our investigation into the importance of single directions for generalisation, soon to appear at the Sixth International Conference on Learning Representations (ICLR), uses an approach inspired by decades of experimental neuroscience — exploring the impact of damage — to determine: how important are small groups of neurons in deep neural networks? Are more easily interpretable neurons also more important to the network’s computation?
