This post finds the optimal quantile level that maximises the Gaussian efficiency of the quantile absolute deviation. Pragmastat recommends Spread — the Shamos estimator — which achieves a 29% breakdown point with high efficiency without requiring quantile tuning. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat We consider the quantile absolute deviation around the med....

Documentation is one of the most valuable artifacts of any technology project or platform. It provides context to new joiners, avoids duplicating responses via Slack/Teams, and facilitates asynchronous communication, but it also requires constant care and feeding. Confluence is where documentation goes to die – Unknown Most of the large enterprises that I’ve worked for have a large corpus of documentation in a wiki of some sort. M..

tl;dr conn.execute ( "select * from ... where ... in (select value from json_each(?))" , ( json.dumps ( list_of_values ) , ) , ) Lists of values in SQLite SQLite doesn’t have an array type as Postgres does, but we can exploit the JSON extension to do operations with arrays. An example of why this may be needed. Let’s say you have a table with names, and you want to select all the id’s of people from a list of names. Som..

COBOL is for Big Data. Well, sort of. Awhile back, I noticed that the COBOL SORT verb was overpowered. Rather than sorting an array of items or even sorting a file, it included a generalized ability to stream in arbitrary inputs — () => Stream[T] —, where T is a key/value pair, and process the outputs in order — SortedStream[T] => (). This power is useful if you are writing a map-reduce program, but excessive for sorting. So, let’s look at ....

Since these are being boosted again, I wanted to say that my views have changed. I do not recommend most people learn Vim (well, sysadmins should know basic insert, write, quit, and undo). I think that modal editing is a niche. It’s fine for people like me: I can barely keep a train of thought going and I constantly forget what I was thinking (It’s a huge problem I have and I didn’t realize this until recently; it’s why I constantly need ..

If you’ve decided to incorporate a graph database into your application stack then this article is for you. Graph databases can be difficult to integrate without some strong foresight. I’m here to help! Having just implemented the latest Neo4j and a revised architecture, I’ve compiled all of my notes and I want to share the decisions we have made. This article will be about how to bring Neo4j into a Rails application in an organized, faul....

Last time we covered an operation in the LWE encryption scheme called modulus switching, which allows one to switch from one modulus to another, at the cost of introducing a small amount of extra noise, roughly $\sqrt{n}$, where $n$ is the dimension of the LWE ciphertext. This time we’ll cover a more sophisticated operation called key switching, which allows one to switch an LWE ciphertext from being encrypted under one secret key to anothe..

Thought I would write done some of the more annoying/interesting software bugs I have had to deal with recently. Both were dealing with an archive system where large amounts of video/audio/images are uploaded into, then searchable. It allows the editing of metadata for each type of content, as well sending to external systems. Problem #1 When a record is being edited a flag “This is being edited” is added to the record and removed on sa..

As we’ve been building Mach engine , we’ve been using a neat little pattern in Zig that enables writing flag sets more nicely in Zig than in other languages. What is a flag set? We’ve been rewriting mach/gpu (WebGPU bindings for Zig) from scratch recently, so let’s take a flag set from the WebGPU C API: typedef uint32_t WGPUFlags ; typedef WGPUFlags WGPUColorWriteMaskFlags ; Effectively, WGPUColorWriteMaskFlags ....

I have a Dell XPS13 laptop and it developed this really annoying habit of randomly freezing for a few seconds and then carrying on as if nothing had happened. It quite often happened in the middle of a work call which made it pretty much unusable.

WFH Day 896 I’m working on too many things at once. The most important one is to replace my Synology NAS with a new one that I built from scratch. My friend was always telling me how great and reliable his TrueNAS system is working for him. Now, I’m replacing my Synology NAS with a more powerful TrueNAS system with a more powerful CPU, RAM and Storage. It’s a steep learning curve to find my way configuring the new machine. It’s also a gr..

It’s hard to overstate how important email is in our modern world. Even as hip new platforms like Slack &co. gain traction in the workplace, so much communication takes place in a crusty old medium that’s outlived every purported “email killer”. Where does it get its staying power from? Email predates much of the Internet as we know it today. Its current incarnation first emerged in the early 80s, though it has roots in earlier forms of....

Tanny and FC17 posted a guide on using GPG with a YubiKey over a year ago , and uh, while it was sometimes updated, it hasn't been recently, and we thought making a new post to note our changes might be a better idea than editing it yet again. Notably, we moved from Tutanota to Thunderbird (with our own Mailcow instance, besides that, we also have a Croc relay and a Jitsi instance running, as for what changed from last time), so we had to ....
