scribu··on Split Keyboard for Professionals
I own a Kinesis Freestyle2. It's collecting dust because I've found the keyboard layout suboptimal. My thumbs would awkwardly reach inwards for the modifier keys.
scribu··on Patatap: Create musical forms with your keyboard
That's so fun!

Having a background rhythm makes it a lot easier to create a decent groove.

scribu··on Should you donate to the Wikimedia Foundation? (2015)
Did you read the part where it says that the people writing the content don't receive any of the donations?

And that the foundation's software initiatives have been largely innefective at getting more/better content? [0]

(I've also donated to Wikimedia in the past and contributed to Wikipedia itself)

scribu··on The Obsolescence of Advertising in the Information Age (2018) [pdf]
The paper proposes a ban on almost all advertising:

> It is hard to believe that as late as the 1970s the Federal Trade Commission (FTC) viewed non-false, non-misleading advertising as anticompetitive conduct capable of violating the antitrust laws.

> Advertising has the power, through repetition and brand image creation, to induce consumers to buy things that they do not really want, to the disadvantage of competitors selling the things that consumers would otherwise buy.

scribu··on A Software Engineer’s Guide to Cybernetics
Ah, this is so handy!

It explains why some Economics degrees have a course on Cybernetics.

scribu··on Show HN: Eiten – open-source tool for portfolio optimization
I'm curious how it differs from PyPortfolioOpt.

scribu··on Nvidia MLOps: The AI LifeCycle for IT Production
The lifecycle diagram is legit.

As for the vendors, Nvidia is just promoting their own services or their partners.

But there aren't any established players yet. It's still a nascent field.

scribu··on The database I wish I had
Indeed:

> test_onefile.c - This file implements a demonstration VFS named "fs" that shows how SQLite can be used on an embedded device that lacks a filesystem.

scribu··on Dropshipping: Hustlers making millions from goods they never handle
Dropshipping has been around for a while.

What's new is using Influencer Marketing to lend more credibility to knockoffs.

scribu··on Algorithmic Theories of Everything (2000)
IMHO, a better title would be "Probabilistic Theories Of Everything"

Contrast with the recent work from David Deutsch, which eliminates all probabilities from physics.

scribu··on Independence, autonomy, and too many small teams
The post makes a good case for why it's a bad idea to split a business problem into slices. Even though you have multiple small teams, they still need to closely coordinate with each other.

But I can't find the next post in the series which proposes a better alternative. Anyone else had better luck?

scribu··on Otto: Friendly Machine Learning Assistant
Model visualization can be useful even for experts, either as an additional sanity check or to debug surprising results.

I couldn't evaluate this Otto thing because I'm on a laptop right now and it looks like the developers assumed that everyone has a 40" screen.

Source: ML is (part of) my job.

scribu··on Nubank acquires Cognitect
Did anyone else notice that the biggest non-academic supporters of functional programming seem to be financial institutions?

Is it due to the nature of the problem space? Is it because finance people tend to be more analytical? Something else?

scribu··on A Full-Motion-Video Consulting Detective
I feel like Black Mirror Bandersnatch gets closer to the promise of interactive video. You get choices which lead to meaningfully different endings. And you get a little reward for playing it through multiple times. :-)
scribu··on Fawkes: Image “Cloaking” for Personal Privacy
Not the author; just a fellow ML practitioner.
scribu··on Fawkes: Image “Cloaking” for Personal Privacy
In theory, yes, you can feed these new distorted images into a new model and defeat the cloaking.

In practice, building new training sets is much more expensive than slightly changing the cloaking algorithm.

scribu··on Terry Tao on some desirable properties of mathematical notation
Shapecatcher is a free webapp that allows you to draw any Unicode symbol:

scribu··on The Adjacent User Theory
> unless the product changes to suit my needs in some way

But isn't that the point of the article? To figure out how to change the product so that it meets more people's needs.

scribu··on The Adjacent User Theory
> No question about whether potential users are interested in the product in the first place?

They do show interest, tho. From the article:

> There are a set of users who show intent for your product but are not quite able to get over the hump. Those are your adjacent users.

scribu··on The Adjacent User Theory
Why is it pathological?
scribu··on Show HN: GUIs for Faster ML Prototyping and Sharing
It's cool that you can immediately update the output whenever the input changes.

But what if the code inside the function changes? Do you have hot reloading functionality?

Streamlit handles this by re-executing the whole script when detecting any code changes. You can cache certain resources (such as the model), but it's fiddly to get right.

scribu··on Scann: Scalable Nearest Neighbors
sklearn's BallTree has a query_radius method [1], but it's exhaustive, rather than approximate.

scribu··on Scann: Scalable Nearest Neighbors
Are you point out the removal of the Apace License header or what?
scribu··on Zettlr – FOSS markdown editor for personal knowledge management and publishing
Potentially!

Looks cumbersome to set up for iOS, tho: https://www.reddit.com/r/Syncthing/comments/ese82l/ios_users...

scribu··on Zettlr – FOSS markdown editor for personal knowledge management and publishing
It's not that. Wikipedia, for example, has a separate "pages that link to this" view.

What makes Roam Research different is "block addressing", i.e. you can get a reference to a single paragraph and use it in other docs (either referencing it or embedding it).

(and of course a nice UX for editing)

scribu··on Zettlr – FOSS markdown editor for personal knowledge management and publishing
The drawback to working directly on Markdown files is that it's hard to synchronize your notes from/to mobile.

If I didn't care about sync, I would use org-roam or some Vim plugin, personally.

scribu··on On moving from statistics to machine learning, the final stage of grief (2019)
This is one of the clearest explanations I've read on the difference between traditional Statistics and Machine Learning.
scribu··on Algolia introduces pay-as-you-go pricing for search
Where you using a different search solution previously? What was it?
scribu··on Mozilla Common Voice Dataset: More data, more languages
What if you first trained a classifier that told you if the uttereance is a single word vs. multiple words? Then, based on that prediction, you would use one of two separate models.

The technique you're thinking of is called oversampling and there are many other general techniques for dealing with imbalanced datasets, as it's a very common situation.

scribu··on Has GitHub been down more since its acquisition by Microsoft?
It's easy to see from the uptime history [1] that there have been many more incidents in April-June than in January-April.

Don't know if that has anything to do with the Microsoft acquisition, but it is concerning.
