nanison Android Developer Verification: Threat masquerading as Protection

Governments are made up of people. People who have at best median level understanding of the things they are ruling about but great self-interest in following the biggest purse to which they can attach themselves.

nanison Show HN: A terminal spreadsheet editor with Vim keybindings

I was able to test the keystroke-doubling and that works well in Windows Terminal now. I am going to try out the formulas later.

nanison Show HN: A terminal spreadsheet editor with Vim keybindings

This looks good, but, I noticed:

> Supported Functions (v1) > SUM, AVERAGE, COUNT, MIN, MAX, IF

I would recommend switching to numerically stable algorithms for adding numbers and taking their averages sooner rather than later.

Looking at the code[1], it looks like you are simply summing the numbers and dividing by count. If that is indeed the case, please switch to a stable average[2]. See also [3].

Additionally, I tried to test the executable[4] on Windows, but there is something wrong with input. Using Windows Terminal Version: 1.24.10921.0, characters are doubled on input. Regular Vim compiled using Visual C++ does not have this issue.

When I press `:`, I get `::` in the COMMAND line. Then, every key I press gets doubled. This means I cannot `:q!`. :-)

nanison Interview with Øyvind Kolås, GIMP developer (2017)

Not really -- It invites speculation as to why they were not published for 9 years. And, are the words spoken a decade ago still valid?

nanison A Farewell to the ArcoLinux University

It is your twist and unjustifiable generalization of the author's words about the author himself:

> "aging is a synonym of cognitive decline"

compared to:

> As I near 60, I’ve come to realize I simply don’t have the same mental sharpness or stamina I used to.

The author did not say anything about anyone else.

nanison Calculating the largest known prime in Ruby

1 is 2 to the power 0 ... 0b0001

shifted left once, it becomes 2 to the power 1 ... 0b0010

shifted left twice, it becomes 2 to the power 2 ... 0b0100

shifted left three times, it becomes 2 to the power 3 ... 0b1000

etc until

shifted left 136_279_841 times, it becomes 2 to the power 136_279_84 ... 0b1000...many zeros...0000

subtract 1, it becomes

nanison Fearless SSH: Short-lived certificates bring Zero Trust to infrastructure

This was corrected to:

> ... SSH certificates issued by the Cloudflare CA include a field called valid_principals

which indicates it wasn't just the spelling of `principals`.

nanison Fearless SSH: Short-lived certificates bring Zero Trust to infrastructure

> the SSH certificates issued by the Cloudflare CA include a field called ValidPrinciples

Having implemented similar systems before, I was interested to read this post. Then I see this. Now I have to find out if that really is the field, if this was ChatGPT spellcheck, or something else entirely.

nanison Ask HN: Resources about math behind A/B testing

Early in the A-B craze (optimal shade of blue nonsense), I was talking to someone high up with an online hotel reservation company who was telling me how great A-B testing had been for them. I asked him how they chose stopping point/sample size. He told me experiments continued until they observed a statistically significant difference between the two conditions.

The arithmetic is simple and cheap. Understanding basic intro stats principles, priceless.

nanison Workman Layout for Vim

This[1] links to http://www. workmanlayout.com/blog/ which is a 404. (space inserted to avoid auto link generation).

Going to the main page of that site reveals some articles from the past few years, but also has online casino and crypto links disguised as posts. E.g.:

> is your premier source for crypto insights, covering the latest news, trends, and guides on blockchain, cryptocurrencies, and cybersecurity. Whether a beginner or a pro, you can find valuable information and tips to stay ahead in the Web 3.0 era.

Weird and shady.

I keep seeing all these people fancy keyboards and interesting looking layouts except that it takes them six to 10 attempts to type anything correctly. Don't really get the point, but having got curious about this "workman" layout and regretted trying to find out.

I was thinking of a pane layout manager ... Anything like that around?

nanison Mozilla will be retiring the Mozilla Location Service

The rather troubling part of this announcement in a GitHub issue is that this nugget comes out in a seemingly innocuous comment[1]:

>> Firefox still uses MLS for `browser.region.network.url`; will that also move to Google Location Services?

> This endpoint will be migrated to another service (classify-client) that will return the expected response. We'll adjust DNS entries when it's time to make that move so firefox won't see any difference.

What exactly is this "classify-client" service?

Note also this led me to discover for the first time that this is a thing[2]:

> Geolocation for default search engine

> In order to set the right default search engine for your location, Firefox will perform a geolocation lookup once by contacting Mozilla's servers and store the country-level result locally. This connection happens on the first start of Firefox – in case you want to prohibit that, you will have to preconfigure the browser and set the browser.search.geoip.url preference to a blank string.

nanison Chess, unlike war, is a game of perfect information

Exactly. In particular, "perfect information" means you know all the strategies available to your opponent. You also know that your opponent knows this. And you know that your opponent knows that you know that your opponent knows that you know all the strategies to your opponent ad infinitum symmetrically.

In this context, a strategy is a function that maps every history of moves by you and your opponent to an action. So, while chess is theoretically a game of perfect information, in practice it is less so.

Real war is not a game of perfect information, because you do not know all the strategies available to your opponent. In addition, you and your opponent's priors may have an intersection of zero measure which makes things very interesting.

War is what happens when a certain kind of people try to play the game of chicken which is usually not taught in the kind of fun programs like master's of international studies for members of the preferred party because it is too sophisticated due to the fact that it admits an infinite number of Nash equilibria ... instead, such programs prefer to focus on prisoners' dilemma which, having a dominant strategy equilibrium, is more suitable to ensure such students can go back to the bureaucracy after having passed their classes with perfect As and get us in to war.
