Did you ever imagine that an “Ice Cream” could shake the entire General Motors? In 2010, the Pontiac Division of General Motors received a very funny complaint from one of its customers. It was so weird & bizarre that it took the entire General Motors by storm. However, on reading the entire Case, this definitely
As part of the fastMRI research project to use AI to speed up MRI scans, NYU Langone Health is making a new dataset of de-identified brain MRIs available to researchers and Facebook AI is sharing additional tools and resources.
When computer vision detectors are turned loose in the real world, their performance noticeably drops. In an effort to close this performance gap, a team of MIT and IBM researchers set out to create a very different kind of object-recognition dataset called ObjectNet.
I think it is safe to state that hash tables (e.g. maps in Go, dicts in Python, HashMap in Java, etc.) are far more common than ordered data structures such as trees for in-memory data structures. One data point is that in a talk about C++ hash table optimization at Google ( available in Abseil ), the speaker noted…
30% less disk required compared to using the single best strategy
In this post I'm going to show you a simple way to significantly speedup Python numpy compute performance on AMD CPU's when using Anaconda Python.
Optimizing memory-usage for approximate nearest neighbor search
This paper is by Abutalib Aghayev (Carnegie Mellon University), Sage Weil (Red Hat Inc.), Michael Kuchnik (Carnegie Mellon University), Mar...
Yes, I know, it’s a long text, and it was my conscious decision to write it in this way. But fear not! Imagine that you read a book, take a look at the introduction and first few interesting sections, think about it and then find time to read further. I hope I’ve left enough references, so if you don’t get some ideas…
My problem is not just with the methods—although I do have problems with the method—but also with the ideology.
Managing databases at scale is never easy. One of the options to store, retrieve, and manage large amounts of structured data, including key-value and tabular formats, is Apache Cassandra. With Cassandra, you can use the expressive Cassandra Query Language (CQL) to build applications quickly. However, managing large…
Get to know and learn how to use some less-known features of Version 12 of PostgreSQL. You'll surely discover something new for yourself.
Mergeable replicated data types Kaki et al., OOPSLA’19 This paper was published at OOPSLA, but perhaps it’s amongst the distributed systems community that I expect there to be the greatest in…
Oscar Wilde once said, “it’s an odd thing but anyone who disappears is said to be in San Francisco.” Indeed, with the weather, view, and diversity, San Francisco is one of the most beautiful cities in the U.S. But then, every city has a dark side, and San Francisco is no exception. San Francisco, as […]
Bespoke cyber investigations and dark web intelligence — threat actor attribution, asset tracing, digital forensics, and ransomware negotiation.
This article will provide the reader with a brief overview for a number of different Linux commands. A special emphasis will be placed on explaining how each command can be used in the context of performing data science tasks. The goal will be to convince the reader that each of these commands can be extremely useful…

We live in a data-intensive, data-driven world! Organizations of all types collect, store, process, analyze data and use it to inform and improve their decision-making processes. The AWS Cloud is well-suited to all of these activities; it offers vast amounts of storage, access to any conceivable amount of compute…
CockroachDB 19.2 improves latency, reliability, and usability. We’re bringing the speed of distributed transactions closer to the theoretical minimum.
A problem that would have been discovered in the future would now be captured by the SMART stats when the process reads that section of disk today.
You can process data that doesn’t fit in memory by using four basic techniques: spending money, compression, chunking, and indexing.
Andy attempts to revive his blog by predicting what databases will look like in the year 2065.
Using vectorized processing in an execution engine makes more efficient use of modern CPUs by changing the data orientation (from rows to columns) to get more out of the CPU cache and deep instruction pipelines by operating on batches of data at a time.
OR in the WHERE condition of a PostgreSQL database query is usually a cause of bad query performance. How to rewrite queries without OR.
Are you trying to predict time series but don't know where to start? This blog post will provide a comparison of the most prominent techniques and show you how …

Parallel Commits are an atomic commit protocol in CockroachDB. The feature promises to halve the latency of distributed transactions by performing all consensus round trips required to commit a transaction concurrently.
This made it to the Hacker News front-page too: some very interesting comments there
