exidy··on How Israeli actions caused famine in Gaza, visualized
Your comment that I responded to implied that the British engaged in indiscriminate area bombing while the Americans did not. Nothing to do with who was or was not criticised. Don’t straw-man.
exidy··on How Israeli actions caused famine in Gaza, visualized
> so they could see what they'd hit.

Such as the cities of Nagasaki and Hiroshima?

exidy··on Boeing has started working on a 737 MAX replacement
I think there might be some confusion here. The vertical stabiliser (not the tail) was extended by 40 inches [0] to combat concerns about poor yaw control.

Although the Wikipedia article cites the UK ARB as the influence, it was also in response to the 1959 crash [1] of a 707 being used for training, in which Dutch roll was induced and later became so violent it ripped 3 engines off the wings.

exidy··on SonyShell – An effort to “SSH into my Sony DSLR”
I think it's better to steelman rather than assert ignorance on the part of the person you're replying to.

It is true that people these days associate the DSLR form-factor with professional photography, despite the heavy use of rangefingers by those such as Robert Capa etc not that long ago. And it is also true that both rangefinders and mirrorless ILCs avoid the need for retrofocus designs which in theory should make for higher-quality lenses at the same weight, or similar quality and a lower weight.

As for "better" this is often a matter of preference and it's okay for people to have different preferences. For me personally, I wish there was more experimentation in ILC form factor, it seems most (with a few notable exceptions) ape the pentaprism hump even if they don't contain one.

exidy··on Taking Buildkite from a side project to a global company
I love BuildKite. It might seem obvious now but I feel like BK had two key ideas -- fully declarative pipelines and a hybrid SaaS control plane / customer-managed workers concept that made it so much easier to deploy into large enterprises. That combined with a UI that was clear and a pleasure to work with.

I do wonder how BK will continue in a world that's increasingly dominated by GitHub and and other integrated solutions, but I hope as long as there's a market for quality tools, BK will survive and thrive.

exidy··on Nintendo Switch 2 Dock USB-C Compatibility
> Nintendo will earn millions by keeping it proprietary. Lets stop pretending this is about technical ability or 'protecting' the consumer from a bad ux.

Nintendo ships a dock with every Switch 2. How big is the market for people buying aftermarket docks? Nintendo has always aimed very squarely at the mass market.

exidy··on The time picker on the iPhone's alarm app isn't circular, it's just a long list
This is the problem with the digital world. Time is analogue and continuous, digital clocks are just a quantised approximation.

Midday and midnight are points in time that have no duration -- as soon as they are observed they are passed, so midnight is 12am and midday is 12pm.

This is easier to visualise on an analogue clock with a continuous seconds hand. Although the hand sweeps past 12 it spends no time there.

Alternatively think of a digital clock with very high precision. While your ordinary clock will show 12:00pm at midday for a full minute, your high precision clock might be showing 12:00:00.0000001 -- indisputably "post meridiem".

exidy··on The time picker on the iPhone's alarm app isn't circular, it's just a long list
This isn't right. Midday / midnight are not the 60 seconds it takes for a digital clock to go from showing 12:00 to 12:01. They are the infinitesimally small point in time that mark the transition between "before" and "after".

Like throwing a ball up into air, there is no time where it is not either rising or falling, but there is a point where it transitions from one to the other.

So midday is 12:00pm. As soon as the moment has been observed it has passed, and you are now "post meridiem".

exidy··on China is eating the world
It was not the lockdowns, it was the good fortune of being an island nation coupled with a border control regime so strict it was later found to violate basic human rights.[0]

Australia went down a similar path to similar effect until the proverbial dyke burst and suddenly nobody cared about quarantine any more. The lesson here is that human nature being what it is, you can throw citizens overseas under the bus to appease the majority until they get tired of being locked in.

Seems to provide similar information as https://aviability.com/ although with a slicker interface and monetisation.
exidy··on A short post on short trains
Singapore started building MRTs in 1982 and essentially never stopped. However "just build another line" is a bit glib when you're dealing with a city state of 6 million people on an island roughly 40km x 20km. There is a huge opportunity cost if land is misused or underused.

exidy··on The scam that is Visa Account Updater
You're thinking like an engineer. From the perspective of the bank, you (the individual) has given a merchant (gym etc) a standing authority to bill you. That authority is between you and the merchant, not between your specific card number and their payment processor. Having your card reissued is not a withdrawal of that authority.

Based on the brief detail provided, I think OP's mistake was to cancel/reissue the card rather than dispute the charge / block the merchant.

exidy··on The scam that is Visa Account Updater
This may not even be a case of Visa Account Updater. Recurrent charges (subscriptions, gyms etc) may not even be sent online, they are just processed in batch. Visa/Mastercard is a dual message system where a real-time auth is followed by an overnight batch which clears the auth and posts the actual transaction to the account. Transactions posted in batch cannot be denied per se, but can generate automatic reversals that would be sent in the next batch.

Under the bonnet, card hosts like Base2000 have an underlying account number for the credit facility, and various PANs (card numbers) are attached to that. Even if a singular card is cancelled, transactions posted in batch can be routed to the appropriate credit facility as the host knows all current and past PANs.

If you have subscriptions that are difficult to cancel, the best path is to ask your bank to block and/or dispute the transactions in question. Getting a new card with a new PAN may not be sufficient.

exidy··on Air Traffic Control
There were a great number of inventive aerial navigation systems that predate GPS by many decades. One of my favourite books is Most Secret War[0], a biography by R.V. Jones that details much of the cat and mouse that went into detecting and countering the various systems used by the Axis and the Allies to bomb each other.

exidy··on Microsoft’s original source code
Apologies, I was juggling multiple sources. The Xerox VC investment into Apple is a matter of public record, the figure of $10/share is widely quoted, including in the Walter Isaacson biography of Steve Jobs[0].

Exactly how and when Xerox disposed of its shares is not public record, but it's known to be around that timeframe and certainly Xerox made a profit. The book _Dealers of Lightning_ goes into more detail about the deal if you're interested[1].

exidy··on Microsoft’s original source code
This is a myth. Jobs negotiated access to PARC technology as part of a deal in which Xerox bought shares in Apple at $10/share[0], selling about a year later at $22/share. Those shares would be worth around $5 billion today.

Xerox did later sue Apple for IP infringement, however most of their claims were dismissed[1].

exidy··on Sigma BF Camera
The camera is using Leica L-mount[1] so you have the full range of Leica as well as Panasonic and Sigma lenses available. For the sort of people who invest in Leica glass, $3k AUD will not seem unreasonable and the minimalist aesthetic is right in the Leica wheelhouse.

exidy··on Malaysia is betting on data centers to boost its economy
Malaysia is also (more or less, for business purposes) common law. Indonesia and Thailand are not.

The LCD is clearly connected via VGA. The owner needs to hit the autosync button so the left edge isn’t cut off.
exidy··on Qantas is bringing back Airbus A380s from the California desert
Not quite. Singapore Airlines continued to fly a lot of near-empty planes to Australia during the pandemic, and delivered the first load of Pfizer. I believe Qatar kept flying also.

Qantas basically ceased all international operations except when underwritten by the government.

exidy··on Paul Theroux reflects on the evolving nature of rail travel
In a similar vein I can recommend Alexander Frater's "Beyond the Blue Horizon" [1] as he retraces the original flight path of Imperial Airways from London to Brisbane.

Because it was written in the 80s, it's actually now two histories in one, first the story of Imperial airways he recounts, the second his experience travelling in the mid-80s, well before 9/11 and Covid.

exidy··on I Thought I Was Saving Trans Kids. Now I’m Blowing the Whistle
> Second, I don't know of any treatments for gender dysphoria (in trans people, not people with other conditions that've been misdiagnosed) that "fix" the mind and actually work. Gender reassignment, on the other hand, works, in the sense that it improves peoples' lives (see https://www.scimex.org/newsfeed/transgender-teens-receiving-... for example).

There seems to be a prevalent problem in this area (and perhaps others too) to where the reporting on the "science" seems to be a lot more positive than the science itself. The original article alludes to this -- "stop questioning the science" like it's an open and shut case.

For that particular study, a more accurate headline would be: "In Our Pre-Registration We Expected To Find Improvements on Eight Measures but We Only Found Improvements on Two, Which Were Very Small, and Only For Natal Females."[1] It's not as snappy, but it's more accurate.

That complex and fairly ambiguous outcome gets summarised into an overall optimistic story by the press, which then in turn gets digested into "gender reassignment .. works", not just on HN but on forums all over the internet.

It's not just that study though -- whenever the field is looked at holistically the evidence for the effectiveness of these treatments is not strong.[2][3] and the evidence for such treatments on children (the subject of the article) is even weaker.

Ultimately I believe adults have the right to do as they wish with their own bodies, however when it comes to children we have to be guided by the highest standards of medicine and science.

exidy··on A media-fueled social panic over unmarked graves
> You admit not knowing Quillette, but is a well-known alt-right website who notoriously don't care about facts and as such their content is no more reliable than Putin's Sputnik.

As a media outlet, Quillette is a valid target of criticism but these sorts of vague slurs are easily debunked with a modicum[1] of research[2].

If you don't like the story, criticise the story.

exidy··on Alaska Airlines becomes first U.S. airline to launch electronic bag tag program
Qantas has been using them on its domestic network for some years. Either you print bag tags at the kiosk that are scanned by the automated bag drop, or if you have the Q Bag Tags[1] and have checked in online, you just proceed directly to bag drop.
