What Do Engineering Leaders Care About?

Aggregated on: 2023-06-22 14:00:57

Last week we had our first Engineering Leaders Forum here in the Bay Area. Over 100 VPs and SVPs of Engineering from the Bay Area's leading companies registered. At some point, we had to open up a waiting list. Good problem to have. I have wanted to hold such an event for quite some time. Engineering leaders, as opposed to other personas, lack the opportunity to share their challenges and hear the perspective of others in a very safe environment. In the room last week, we had a few thousand years of experience. Based on the feedback, the format of roundtables was well received. I really appreciate the fact that both Kubiya.ai as well as Devzero, Turing, Uplevel, and AWS chose to sponsor the event and make it happen. I want to talk a little bit about some of the insights that we had from executives in the room. Again, I'll keep it generic so that I wouldn't share anything confidential.

Non-Traditional Project Planning

Aggregated on: 2023-06-22 01:15:57

Most methodology discussions today start and end with how Agile is superior to Waterfall in software engineering; in reality, many other methodologies exist, each with their own pros and cons. Leadership, enamored with being agile, insist on Agile — or at least the perception of — even when another methodology is more appropriate for the project, team, business domain, customer, whatever. I view the bigger problem as methodology for methodology's sake: application without understanding, execution without adaptation. Thou shall do X as defined by said methodology, and so you shall regardless of lack of perceived benefits.

Millions of .Git Folders Were Exposed Publicly by Mistake

Aggregated on: 2023-06-21 20:45:57

2022 has been the year of source code leaks; Microsoft, Nvidia, Samsung, Rockstar, and many more companies have had their source code involuntarily open-sourced. But some new research by Cybernews has revealed that there are millions of private git repositories that are, in fact, not all that private. In this article, we will take a look at the research on exposed git repositories, review why this can be such a problem, and suggest what you can do differently. Nearly 2 Million Exposed Git Repositories Git is a technology that nearly all software developers use to collaborate and version control their software. You will likely be familiar with git repository hosts like GitHub, BitBucket, or GitLab, which all offer turnkey solutions to sign up and start pushing code to your own repositories and collaborating with others. Git can be a tricky technology and prone to user errors that can result in sensitive information being exposed. For example, when you create a new git repository on your machine, a .git folder is created. This folder contains all the information and meta-data about your project since it was created. If you made an edit from 2012 to your application, 10 years later, that edit is still hidden in that .git folder. If you commit an API key on a development branch 3 years ago, it's still inside this .git folder. Basically, unless you are certain you and no one on your team have ever committed anything remotely sensitive, which will be godly if true, this is likely a very sensitive folder.

Quantum AI: Unraveling the Potential of Quantum Computing in Machine Learning

Aggregated on: 2023-06-20 15:45:56

What Is QML? Quantum Machine Learning is a research area that combines quantum physics and machine learning. It uses quantum computing's potential for fast and complex computations to improve the efficiency and effectiveness of machine learning algorithms. This could speed up data processing and potentially reveal new insights from data. Challenges of QML Data encoding schemes: We have plenty of classical data which needs to convert into quantum states to have them as inputs to a quantum machine learning model. This step is crucial because an accurate data encoding scheme ensures that the quantum states are represented properly in the Bloch sphere as amplitudes, basis, or rotations. QML model design: This consists of designing parameterized quantum circuits (PQCs), which learn the latent patterns in the data and extract useful information from it. Usually, Pauli rotation gates are used for building the PQCs. However, better hybrid quantum-classical architectures need to be identified to increase the generalizability of the circuits. The fundamental unit of Quantum Learning: In classical machine learning, there is a fundamental unit of computation known as the neuron, which computes the weighted mean of all the inputs and gives a single numerical value as the output. A similar computational unit called the quantum neuron is required, which inherently uses the quantum mechanical properties to perform computations. Quantum Hardware limitations: The quantum computers available today are in the NISQ (Noisy Intermediate-Scale Quantum) era, which means that they have a few hundred noisy qubits which are only capable of executing quantum circuits up to a certain depth and do not provide accurate results. It also implies that the ability to retain information is limited. Quantum resource management: Due to the NISQ era, there is a limitation on the number of quantum gates that can be run, which indicates that a larger depth circuit will have more noisy results. Also, building fault-tolerant qubits and quantum gates is another challenge. Standardized Evaluation and Benchmarking: With rapid progress in QML research, it is important to set benchmarks for the models, for optimizers, cost functions, and architectures so that standardization can occur in this emerging field. This will aid in the process of evaluating and comparing different QML Algorithms/models for varying datasets. QML Opportunities Data encoding schemes: Efficient and optimal data encoding techniques need to be searched upon such that they accurately represent the quantum state vectors. For example, variational encoding schemes can be one of the approaches. Another could be designing an encoding system based on a given problem; an example could be encoding molecules using graph networks since they capture the essence of molecular structure for quantum chemistry computations. QML model design: There is a huge potential in developing quantum circuit architectures for efficient ansatz design and tailoring them to problem-specific applications. One of the avenues of research is to explore adaptive ansatz design, which can change its width and depth according to the problem size. There exists adapt-VQE, which is used for chemistry, but we need more such kinds of techniques for other areas as well. The fundamental unit of Quantum Learning: Very little work has been carried out to efficiently construct a neuron utilizing the quantum properties. Quantum complexity theory could be studied in detail to address this challenge. It provides tools and techniques to measure the complexity of quantum circuits and even search for optimal ansatz. Additionally, novel architectures could be constructed using the theories of condensed matter physics to search for materials more suitable for quantum computations. Quantum Hardware limitations: Several qubit modalities are currently available for executing quantum computations, such as superconducting, photonic, ion-traps, spin-based, and topological, and significant research is each being carried out to address the challenges they pose. However, it is still undecided which modality will be universal and suit all applications. Furthermore, no standard benchmarks exist that can describe the different hardware compatibility for certain applications. Quantum resource management: Several research groups worldwide are taking inspiration from abstract mathematical fields such as group theory and ring theory to define novel circuit reduction and optimization strategies to reduce the depth of circuits for NISQ devices. Furthermore, better quantum error correction schemes and fault-tolerant procedures are required to optimize resources. Standardized Evaluation and Benchmarking: Developing a standardized framework for evaluating quantum machine learning algorithms that include guidelines for problem description, algorithm implementation, hardware platform, and evaluation metrics. Creating diverse benchmark datasets and defining evaluation metrics that consider accuracy, training time, resource usage, and robustness to noise. QML Assessment Quantum Complexity theory: Applying quantum complexity theory to evaluate QML algorithms involves assessing the efficiency of these algorithms in terms of the required quantum resources, such as the number of qubits, the depth and complexity of quantum circuits, and the number of quantum gates. This analysis can provide valuable insights into the scalability and feasibility of QML algorithms for solving practical problems. Robustness to noise and errors: Evaluate the algorithm's performance in the presence of noise and errors, which are common in current quantum hardware. A successful QML algorithm should demonstrate resilience against these imperfections, maintaining its performance or providing error-correction mechanisms. Resource efficiency: Assess the algorithm's efficiency in terms of required quantum resources, such as the number of qubits, quantum gates, and circuit depth. A successful QML algorithm should minimize resource requirements, allowing for implementation on near-term and future quantum hardware. Accuracy: For supervised and unsupervised learning tasks, prediction or classification accuracy is crucial. The higher the accuracy, the better the QML algorithm performs. It is essential to compare the QML algorithm's accuracy with its classical counterpart to assess any potential advantages. Training and inference time: Evaluate the time required for training and inference using the QML algorithm. Faster training and inference times can provide a competitive advantage over classical algorithms, particularly for large-scale problems or real-time applications. Scalability: Assess the algorithm's scalability with respect to the size of the problem or dataset. A successful QML algorithm should maintain performance as the problem size increases, given the limitations of available quantum hardware.

Building the Best Kubernetes Test Cluster on MacOS

Aggregated on: 2023-06-20 14:00:56

As a platform engineer of many years now, Kubernetes has become one of those ubiquitous tools that are simply a must-have in many of our clients’ tech stacks. Considering that the big three cloud vendors (AWS, GCP, and Microsoft Azure) all now offer their own flavor of managed Kubernetes services, it is easy to see how it has become ever more prolific in the “cloud-native architecture” space. Like all cloud-native technologies, Kubernetes can be a challenge to test locally. On many of our projects, developers often use Docker-compose instead of Kubernetes to test their applications locally, which inevitably causes some friction when deploying them to a cloud environment. Platform engineers also need to test their Kubernetes infrastructure and manifests and often resort to using dedicated cloud environments to do so, which can be quite expensive. What was needed was a way to get as close as possible to a cloud-based managed cluster on a laptop.
