Maximizing the Potential of LLMs: Using Vector Databases

Aggregated on: 2023-04-20 18:30:18

LLMs do Natural Language Processing (NLP) to represent the meaning of the text as a vector. This representation of the words of the text is an embedding. The Token Limit: The LLM Prompting Biggest Problem Currently, one of the biggest problems with LLM prompting is the token limit. When GPT-3 was released, the limit for both the prompt and the output combined was 2,048 tokens. With GPT-3.5, this limit increased to 4,096 tokens. Now, GPT-4 comes in two variants. One with a limit of 8,192 tokens and another with a limit of 32,768 tokens, around 50 pages of text.

Static Proxies or Rotating Proxies: Which One Should You Choose?

Aggregated on: 2023-04-20 17:30:18

Data center proxies come from servers in data centers, while residential proxies come from real people's connections. Static proxies mostly come from data centers, while rotating proxies are residential, although there are exceptions for Residential proxies. Both IPv4 and IPv6 addresses can supply static and rotating proxies, but static IPv4 proxies may be harder to come by since they've all been assigned. IPv6, on the other hand, has trillions of available IP addresses.

Kafka: The Basics

Aggregated on: 2023-04-20 13:45:18

Data synchronization is one of the most important aspects of any product. Apache Kafka is one of the most popular choices when designing a system that expects near-real-time propagation of large volumes of data. Even though Kafka has simple yet powerful semantics, working with it requires insight into its architecture. This article summarizes the most important design aspects of Kafka as a broker and applications that act as data producers or consumers. About Kafka Apache Kafka originated on LinkedIn and was developed as a highly scalable distribution system for telemetry and usage data. Over time, Kafka evolved into a general-purpose streaming data backbone that combines high throughput with low data delivery latencies. Internally, Kafka is a distributed log. A (commit) log is an append-only data structure to whose end the producers append the data (log records), and subscribers read the log from the beginning to replay the records. This data structure is used, for example, in the database write-ahead log. Distributed log means that the actual data structure is not hosted on a single node but is distributed across many nodes to achieve both high availability and high performance.

But new methods are constantly emerging to make the PR lifecycle smoother. These often mix automation and human interaction to reduce the time to merge. In this article, you’ll learn about some of the newer tools that help automate your workflow, including GitHub Actions, code owners, and LinearB’s very own gitStream.

Continuing Hello World

Aggregated on: 2023-04-20 02:15:18

I taught myself to code from scratch. I just started writing in Basic on my Sinclair when I was in kindergarten and “got it.” I later picked up the books and courses easily without that initial study period of formal training. When I got to advanced academic materials, I already knew pretty much everything. As a matter of fact, I never learned much from teachers. I learned to read mostly on my own and followed through with most disciplines. This isn’t a “brag” because the reason for that is a learning disability. It’s hard for me to understand teachers and communicate with them. This was a problem in my childhood but became a bigger problem when I started to teach programming in a local computer lab at 16. I was a terrible instructor. Typically we would mimic the skills of a good role model when performing a task. I didn’t have any good teachers. At least not good for my learning disability.

Jira Anti-Patterns

Aggregated on: 2023-04-20 02:15:18

If you ask people to come up with popular attributes for “Agile” or “agility,” Scrum and Jira will likely be among the top ten featured. Moreover, in any discussion about the topic, someone will mention that using Scrum running on top of Jira does not make an organization Agile. However, more importantly, this notion is often only a tiny step from identifying Jira as a potential impediment to outright vilifying it. So, in March 2023, I embarked on a non-representative research exercise to learn how organizations misuse Jira from a team perspective as I wanted to understand Jira anti-patterns. Read on and learn more about how a project management tool that is reasonably usable when you use it out of the box without any modifications turns into a bureaucratic nightmare, what the reasons for this might be, and what we can do about it.

Breaking the Wall Between Dev, Sec, and Ops

Aggregated on: 2023-04-18 21:30:17

DevSecOps, in layman's language, is a combined form of software development, security, and software operations. According to Gartner's research, "It is estimated that at least 95% of cloud security failures through 2022 will be the fault of the enterprise". Therefore, while developing any application, the developer must not have loose ends that may make an enterprise vulnerable to such attacks. Similarly, DevSecOps is understanding the software and learning to code while learning to operate and maintain that code at the same time. It is essential to keep in mind that a single security breach can lead customers to lose confidence in any business. Therefore, it is vital to prioritize the maintenance of rigorous security measures. DevSecOps involves integrating security into both application development and operations, as well as promoting collaboration between teams and leveraging automation and tooling to construct robust and secure applications. In the DevSecOps approach, security is addressed proactively during the development process rather than as an afterthought. Security testing and bug fixing are integrated into the development cycle to detect security vulnerabilities early in the software development life cycle. This approach facilitates innovation, boosts developer velocity, and allows for speedy release cycles while maintaining a focus on security. DevSecOps has proven beneficial for achieving faster development, more rapid feature releases, and the implementation of agile practices. By integrating security into the development process from the start, DevSecOps helps to reduce the risk of security breaches and other cybersecurity threats that can be costly to organizations in terms of reputation, legal liabilities, and financial losses.
