UPDATE Several years ago on my 68th birthday I wrote up 68 bits of advice for my adult children, and posted them here. The bits were extremely popular, and they were widely shared by others. I was encouraged to write up more bits of wisdom on my following two birthdays. On my 70th birthday I wrote up 103 bits of advice I wish I had known earlier, which were also widely shared. The first six bits a
Anna: A Crazy Fast, Super-Scalable, Flexibly Consistent KVS
There’s fast and there’s fast. This post is about Anna*, a key/value database design from our team at Berkeley that’s got phenomenal speed and buttery smooth scaling, with an unprecedented range of consistency guarantees. Details are in our upcoming ICDE18 paper on Anna. Conventional wisdom (or at least Jeff Dean wisdom) says that you have to redesign your system every time you scale by 10x. As re

PDF of All 3 Essays | Discussion Page The following essays by Jack W. Reeves offer three perspectives on a single theme, namely that programming is fundamentally a design activity and that the only final and true representation of "the design" is the source code itself. This simple assertion gives rise to a rich discussion—one which Reeves explores fully in these three essays. What Is Software D
Background: About five years ago, within Google we started publishing a series of C++ tips, about once a week, that became known as the “C++ Tips of the Week” (TotW). They became wildly successful, and we are still publishing them to this day (indicating that a language as rich as C++ will not deplete us of topics anytime soon). Not only do we discuss the finer points of the language, but in true

TLA+ in Practice and Theory Part 1: The Principles of TLA+ 25 May 2017 This is the first installment in a four-part blog post series about TLA+. Part 2, Part 3, Part 4. A video of a 40-minute talk that covers parts of this series. If you find TLA+ and formal methods in general interesting, I invite you to visit and participate in the new /r/tlaplus on Reddit. Thinking doesn’t guarantee that we won
The ancient microwave in my first apartment. It had two knobs: one for time, one for power. It's immediately obvious how to cook something for how long, how to add more time, etc.All other microwaves that I've used I had to have someone explain to me what buttons to press in what order to do even the simplest things. And I've never seen anyone use all of those fancy buttons. I have another sad sto
Simply put, what are your favorite talks or trainings? It could by a one-off lecture about a specific concept or a series of talks about a language. Maybe it's a TED talk or a session from a con. Either way, what's that one talk that changed the way you think and you feel everyone needs to see? grin Here we go...For "laughing at ourselves" and oddities of computer languages, there is "Wat" by Gary
This list identifies the top ten CWEs in the Cybersecurity and Infrastructure Security Agency’s (CISA) “Known Exploited Vulnerabilities (KEV) Catalog,” a database of security flaws in software applications that have been exposed and leveraged by attackers. Our analysis/key insights about the list are available here, and our methodology for creating the list is here.
Spelling correction & Fuzzy search: 1 million times faster through Symmetric Delete spelling correction algorithm The Symmetric Delete spelling correction algorithm reduces the complexity of edit candidate generation and dictionary lookup for a given Damerau-Levenshtein distance. It is six orders of magnitude faster (than the standard approach with deletes + transposes + replaces + inserts) and la
2019 UPDATE: Since this post came out, I co-authored a book about it called Super Thinking: The Big Book of Mental Models. Around 2003 I came across Charlie Munger’s 1995 speech, The Psychology of Human Misjudgment, which introduced me to how behavioral economics can be applied in business and investing. More profoundly, though, it opened my mind to the power of seeking out and applying mental mod

To be a good programmer is difficult and noble. The hardest part of making real a collective vision of a software project is dealing with one's coworkers and customers. Writing computer programs is important and takes great intelligence and skill. But it is really child's play compared to everything else that a good programmer must do to make a software system that succeeds for both the customer a
What is Torch? Torch is a scientific computing framework with wide support for machine learning algorithms that puts GPUs first. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation. A summary of core features: a powerful N-dimensional array lots of routines for indexing, slicing, transposing, … amazing interface to C, via
