As a senior First Lieutenant, I volunteered to teach new Second Lieutenants about defensive cyberspace operations. Over the course of a year I spent more than twelve hours with three different Cyber Basic Officer Leaders Course (BOLC) classes; each time, they asked the same question: what did your missions ac- complish? Each time, I struggled for an answer. Permalink.

Good, but I didn’t feel very engaged with the music. I was in the Lower Orchestra section, in the 16th row - and pretty tired, that Monday evening. I like their music, but I found myself drifting off, thinking about other things. Thinking much at all is a bad sign for me when I’m watching live music. I usually find it very engrossing & uplifting - ideally, I get carried away by the music and exist fully in the moment for the duration.....

Let $X_1, X_2$ be i.i.d. random variables that follow the standard normal distribution $\mathcal{N}(0,1^2)$. In the previous post , I have found the expected value of $\min(|X_1|, |X_2|)$. Now it’s time to find the value of $Z = \max(|X_1|, |X_2|)$.

This post builds upon " I decided to trust cloud storage ". If you didn't read it, please spare a few minutes for going through it for a better context. As I started to move my files to cloud, a lot has happened. I've decided on a single provider for my files, bought extended file revision membership on said provider, and more importantly, started to move my files over there. The backup plan is not completely realized yet, but progressing....

A really cool, recent question on Stack Overflow was about how to map a nested collection into a Java Map with jOOQ. In the past, I’ve blogged about the powerful MULTISET operator many times, which allows for nesting collections in jOOQ. This time, instead of nesting data into a List

As part of my job I routinely create new Github repositories for my colleagues. One unfortunate side-effect is that I am automatically subscribed to all those repositories and get mails for any new issues, pull requests and so on. This culminated in hundreds of mails over the weekend when we activated renovate for all repositories. But since I don’t work on these repositories, I don’t need any notifications. Now Github offers me two w....

How do you tell when it’s time to deprecate a system? If something mostly works OK, is it worth spending time and effort replacing its functionality? At Artsy, we realized several years ago that we needed to be able to group a bunch of artworks together. If we wanted to have a page with all of the ceramics by Lucio Fontana , or contemporary prints from the IFPDA Fair Sprint 2022 , or a gift guide curated by Antwaun Sargent , we needed ....

I just signed a lease for my second apartment since moving to New York City after college. Some friends asked me for advice on how to find an apartment here, and I didn’t realize at first how many opinions I have on the whole process. I’ve tried to distill my thoughts and approach here. Renting an apartment in New York is all about tradeoffs, mostly between time and money. If you’re willing to spend more time seeing apartments in person, ....

In part one of the SOC Metrics series, I introduced the idea that success requires the right person doing the right things in the right ways . That article also described several foundational metrics , ways to measure the SOC’s ability to produce meaningful results. Part two then focused on measures of performance (MOPs), which assess whether or not (and to what degree) the SOC is doing the right things . This article delves in..

I prefer a hands-off approach to management. Describe a goal, give me the freedom and resources to achieve it, and I will. The success of that approach, which the Army calls “mission command”, ultimately depends on the right person doing the right things in the right ways . Unfortunately, many focus on that first criterion but neglect the second and the third. In many cases, that leads to failure. In the final days of my last job, in a....

I started as Heroku GM a few weeks ago with intense enthusiasm to be a part of such a storied team. As you might expect, the last few weeks have not been what I would have imagined. But, contrary to what you might expect, I’m energized. I’ve been deeply impressed by the skills and dedication […] The post We’ve Heard Your Feedback appeared first on Heroku .

I’ve recently written a series of articles about Gherkin: its usage for requirements gathering , about its uses in BDD , and a lower-tech alternative to Cucumber , which I’m still experimenting with. I wanted to showcase all of these ideas brought together, as well as show how comfy modern Python tooling can be. But more than writing code, I would need to explain my reasoning as we draft the program. So I picked up again a tool I alway..

Let’s explore how a file-format design exercise turned into reinventing the wheel, and let’s all appreciate how lucky we are that the protocols that the internet are built on have fantastic public documents called RFC s. Designing a file format I was idly thinking about designing a good binary file format for a side project of mine called qrxfil . The project aims at QR-code-based file export: split a file in many pieces (based on conte..

Motherhood is a beautiful and ongoing learning experience. But what about being a working mom? Today, I had the opportunity to speak with two super moms at Snyk, Noa Korem and Amanda Parks, about how they felt returning to work after maternity leave.
