Getting my feet wet with Kubernetes

stp2y0 CommentsNewscoding, community, development, devops, engineering, haskell, inclusive, kubernetes, software

Recently, I’ve spent some time playing around with Kubernetes (K8s). Having never used it before, I gave it my humble first try. I used it as part of a project where I wanted to use self host some tools on a VPS and write some server code for some life automations and potentially a blog in the future. You can find the Github Repo for the project at the time of writing for it here. Did I need to use K8s? Nope. Should I have used K8s? Probably not. My situation and setup really doesn’t call for K8s nor does…

Unlocking High-Accuracy Differentially Private Image Classification through Scale

stp2y0 CommentsNews

Research Published 17 June 2022 Authors Soham De, Leonard Berrada, Jamie Hayes, Samuel L. Smith, Borja Balle A recent DeepMind paper on the ethical and social risks of language models identified large language models leaking sensitive information about their training data as a potential risk that organisations working on these models have the responsibility to address. Another recent paper shows that similar privacy risks can also arise in standard image classification models: a fingerprint of each individual training image can be found embedded in the model parameters, and malicious parties could exploit such fingerprints to reconstruct the training data from…

File System Organization Like Windows, the files on a Linux system are arranged in what is called a hierarchical directory structure. This means that they are organized in a tree-like pattern of directories (called folders in other systems), which may contain files and subdirectories. The first directory in the file system is called the root directory. The root directory contains files and subdirectories, which contain more files and subdirectories and so on and so on. The basic three commands include: pwd (print working directory) cd (change directory) ls (list files and directories). pwd The directory we are standing in is…

Research Published 20 June 2022 Authors Zhaohan Daniel Guo, Shantanu Thakoor, Miruna Pîslar, Bernardo Avila Pires, Florent Altché, Corentin Tallec, Alaa Saade, Daniele Calandriello, Jean-Bastien Grill, Yunhao Tang, Michal Valko, Rémi Munos, Mohammad Gheshlaghi Azar, Bilal Piot Second-person and top-down views of a BYOL-Explore agent solving Thow-Across level of DM-HARD-8, whereas pure RL and other baseline exploration methods fail to make any progress on Thow-Across. Curiosity-driven exploration is the active process of seeking new information to enhance the agent’s understanding of its environment. Suppose that the agent has learned a model of the world that can predict future events given…

Uncovering the truth about Bitcoin stock holders | Deephaven

stp2y0 CommentsNews

In my last post, I used my understanding of Deephaven and its tools to predict some stock prices. This was a part of my more extensive study of the stock market.In March, a company called MicroStrategy took a $205 million Bitcoin-backed loan to purchase a large sum of extra Bitcoin. They wanted to protect their monetary assets from inflation. This purchase -- or rather bet -- is quite risky, as something like a margin call from low Bitcoin prices could cause them to lose a lot of their money. A possible side effect is a stock price that fluctuates based…

Who’s who?: real-time face recognition | Deephaven

stp2y0 CommentsNews

Facial recognition technology is a powerful tool - computer vision can identify a person simply by scanning their face. You've encountered this whenever your phone recognizes friends to help you organize your photos, or if you need a face scan to enter your top secret laboratory. More seriously, facial recognition technology serves important purposes for law enforcement and surveillance experts. We'll leave that to the professionals. In this blog, I implement facial recognition in real time on the movie Avengers: Endgame, using Deephaven's powerful real-time analytic tools. We'll show you how to easily ingest the data into a platform where…
