In this article, we share empirical measurements from our experiments in using Postgres to index and search over 10,000 top GitHub repositories using pg_trgm on only a Macbook. This is a follow up to “Postgres Trigram search learnings” , in which we shared several learnings and beliefs about trying to use Postgres Trigram indexes as an alterative to Google’s Zoekt (“Fast trigram based code search”). We share our results, as well as ....
As we celebrate Black History month, it’s an opportunity to reflect upon the last 12 months, on how Thoughtworks North America has been able to reflect upon and respond to the events of last year, and on my personal learnings and areas for growth.

안녕하세요~^^ 코스모스팜 회원관리 플러그인 소셜 로그인 시 최초에는 워드프레스 사용자로 새로 회원가입을 한 후 로그인을 하며 이후에는 로그인만 하게 됩니다. 기존 워드프레스 사용자 정보에 등록된 이메일로 새로 회원가입 시에는 이메일을 임의의 문자로 변경해서 가입을 하고 있습니다. 소셜 로그인 이메일 중복 문제 관련해서는 추후 연구 개발하여 개선해서 업데이트하도록 하겠습니다. 고맙습니다.

This post improves MAD bias-correction by using the Harrell-Davis quantile estimator for the inner median, achieving better finite-sample behaviour. Pragmastat recommends Spread — the Shamos estimator — as a more efficient robust scale alternative. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat The median absolute deviation ($\textrm{MAD}$) is a robust measure of sc....

Annual reviews have closed from the new year so we’re now into performance review season. A lot of people I work with seem to have a lot of reservations and anxieties about this time of year. I find that if you keep the following things in mind you tend to have really smooth and easy reviews.

It seems like just yesterday I was switching subsidiary companies at my resident multinational conglomerate, trading in my gig in enterprise business software for something more acutely interesting to me: surgical robotics. And the three+ intervening years have been not only a grand ole time, but also marked a clear shift in what I actually do at work. The last time I wrote a post like this, my main job was building the things other p..

Me Hi! My name is Valtteri. I’m a hacker. I love to apply knowledge across domains and spend much of my limited freetime trying novel things on a computer. Some of those experiments end up here as writeups. Beyond my love for computers and security, I enjoy books, board games, trekking, and fishing. I work as a Senior Security Engineer at Konecranes. Previously, I worked as a freelancer and developed an OPC UA security scanner.
About seven years ago, I presented the Eve Framework in a very crowded Python room at FOSDEM 2014 in Brussels. If you don’t know about FOSDEM, well, you should check it out. Every year thousands of developers who recognize themselves with the free and open-source movement gather in Brussels from all over the world. And I mean thousands of them. According to Wikipedia, since 2011, the meeting hosts about 4,000 visitors every year. It’s huge,..

TL;DR: Some Linux distros and even different kernel versions within a distro have disabled IRQ time accounting. In such case, your monitoring tools will report zero time spent in hardware interrupt handlers (shown as %hi, %irq, hiq, etc). It’s easy to check how your kernel is behaving by looking at /proc/stat and you can still measure interrupt CPU usage using perf and a little creativity . Index Index Problem Explanation Kernel....

In late August 2020 I read The Dream Machine and it is my favorite book of 2020. It is an incredible overview of a sliver of computer pioneers in the 1960s-1980s and how one man was instrumental in tying all their narratives together. One of the strands the book follows is the group at PARC (and other places) that firmly believed in the notion of interactive computing. Over the last year, I’ve repeatedly been introduced to this strand of th..

In retrospect, 2020 was an unprecedented year, yet still too eerily familiar.  As early as Jan 8th, 2020, there were warning signs that the COVID-19 virus was bound to rapidly propagate outside of Wuhan, China, an eventuality many governments and organizations were not readily prepared for.
At a conceptual level, most would agree on the value of Diversity, Equity and Inclusion (DEI). Tonnes of studies show how diversity of thought fosters improved innovation and problem solving. To put it bluntly; it translates into stronger client engagement and overall increased financial performance. When organisations resort to making superficial attempts to include underrepresented groups to tick a box, that’s where the problems begin.
This post is part of the FastAPI series. This is another post related to FastAPI(indirectly) in which I am going to discuss how to use GraphQL based APIs to access and manipulate data. I already have discussed how you can make Rest API in the FastAPI framework in the previous post. We will be learning some basics of GraphQL and how graphene helps us to use Python for writing a GraphQL based application. So, let’s get started! What is GraphQ....
