donaltroddyn··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights (2018)
Ryanair is 34 years old and flew more PAX in the last two years than Hawaiian has in its entire history, with significantly fewer accidents and incidents, even if you only consider those that occurred while both airlines were flying. It's hard to find historical PAX numbers for Hawaiian, but it seems that Ryanair overtook them at some point in 2000.

I don't see any basis for your claim that their safety record is "practically blank". They are widely considered the world's safest airline - a spot they shared with Southwest until ‎SWA1380.

donaltroddyn··on Wirelessly charging electric cars as they drive
Auto Express seems to be the source of those figures, which show that diesel cars as a class have (slightly) higher average mileage than Teslas, and roughly 33% higher average mileage than full electrics as a class.

Again, it seems like selection bias, in that those high-mileage drivers who can use electric do, and those that can't buy diesel. Presumably there is a cohort of diesel drivers who would switch to electric if they offered sufficient range or faster charging, especially as diesels outnumber electrics ~2.5:1 in the UK [2].

donaltroddyn··on Wirelessly charging electric cars as they drive
Presumably people whose use case would require frequent charging in places other than their home (or work) don't buy electric cars, so there's probably some selection bias here.
donaltroddyn··on SUVs parked on cargo ships reveal scope of U.S. auto market glut
I wondered what the actual rates would be and found this article: https://www.jstor.org/stable/27739679

It seems that in the late 19th century in the U.S., the annual death rate from horses was approximately 5 per 100,000 inhabitants. That surprised me, as it's ~1/3rd the current U.S. road traffic fatality rate, and as horses were used for more than just transport.

I couldn't find any figures, but obviously the distance travelled per capita has exploded, so it's likely that horse riding is at least several orders of magnitude more dangerous than driving.

donaltroddyn··on In World War I, British biplanes had wireless phones in the cockpit
Until relatively recently, military signallers who carried radios were called Radio Telephone Operators - manuals are still full of references to radio telephones.
donaltroddyn··on Honda bucks industry trend by removing touchscreen controls
I'm not at all convinced that voice recognition are better or safer than well designed physical controls.
donaltroddyn··on The road to riches is this simple: Drive a crappy car (2019)
Almost all ICE cars here in Ireland are manual, and unfortunately I see people texting away on their phones every day. I'm not certain it'll be the deterrent that you expect it to be.
donaltroddyn··on When good ideas make bad business
This is a shockingly uncompassionate perspective - is it satire?

Assuming it's genuine, it's also misguided. Almost no-one wants to be obese, alcoholic, etc - accessible healthcare will reduce the incidence of all of these, which in turn will reduce the externalities associated with them.

You also don't need further state control to discourage smoking, drinking, junk food, etc - taxation is the mechanism used globally to discourage undesirable behaviour.

donaltroddyn··on Google to end 'Double Irish, Dutch' tax scheme: filing
When Ireland rejected by referendum the Lisbon Treaty in 2008, a series of clauses known as the Irish Guarantees were added. One of those guarantees is:

> Nothing in the Treaty of Lisbon makes any change of any kind, for any Member State, to the extent or operation of the competence of the European Union in relation to taxation.

Ireland holds a veto (as do all other EU countries) on any proposed Common Consolidated Corporate Tax Base, so the chances of a CCCTB as commonly envisaged being enacted is exactly zero.

donaltroddyn··on Toyota believes hydrogen fuel cells are the future
Current hydrogen production is largely from cracking methane, where natural gas is the feedstock (and also energy source) - it is much cheaper than production from electrolysis.
donaltroddyn··on Face recognition in European police forces
It is also predicated on the Public Services Card, a de facto national ID card by stealth (the electorate in Ireland has resisted any attempts to implement a national ID card) which is "not compulsory but is mandatory for services" (from https://www.thejournal.ie/regina-doherty-public-services-car... ) and of which the Data Protection Commission has ruled "that the State’s retention of personal data on the 3.2m cards in existence is unlawful" (from https://www.irishexaminer.com/breakingnews/ireland/data-comm... ).

The government contest this result (and have been accused of using budgetary measures to hamper the DPC's ability to investigate and enforce their findings), but the use of facial recognition in Ireland is currently unlawful, and, personally speaking, a disgrace.

In terms of the use of facial recognition by the Gardaí, the truth is that we don't know whether it has been used - only that its fruits haven't been included in any book of evidence.

donaltroddyn··on Centrifugal Machine Guns
Yeah, anyone who's had a brass casing land down the back of their neck can attest to how much water heat they draw away from the weapon.

I also wonder how important the gas exchange caused by the mechanical cycling of the action is to cooling, as most modern rifles are pretty well sealed when in battery.

donaltroddyn··on Centrifugal Machine Guns
A 5.56 bullet will leave a full length 20" rifle barrel in under 2ms with something like 1500J kinetic energy, which is greater than 750kW. I don't know what the acceleration profile is like in the barrel - I suspect it might peak much higher than that.
donaltroddyn··on Verizon/Yahoo Blocking Attempts to Archive Yahoo Groups – Deletion: Dec. 14
If you are a company, GDPR does apply to data on physical letters and local emails. A large part of the preparation for the introduction of GDPR enforcement was companies getting a handle on what they had stored in various media.
donaltroddyn··on No to Chrome
Badly worded on my part, but it's my own product. I use Puppeteer to run headless Chrome instances in AWS Lambda to evaluate the network traffic associated with advertising data collection. I have a toolchain built around Puppeteer and CDP, which is in use by customers, so migration isn't a viable option for me.
donaltroddyn··on No to Chrome
In terms of browsers, I have moved back to Firefox from Google for my personal/professional browsing, but I have a product that is heavily reliant on Puppeteer and CDP. There are moves towards interoperability in Firefox, but that's my current blocker.
donaltroddyn··on Something Changed at Tesla
I live in Europe (Ireland) and F150s, Rangers, and other pickups are very common as work vehicles here. There's also a lot of 4x4s like Land Cruisers and Defenders with bull bars, which are presumably less safe for pedestrians.
donaltroddyn··on Show HN: Calculate your chances of getting a work visa to live in top countries
I'm an Irish citizen and it gives me an 87% chance of getting a work visa for the UK, where Irish citizens have the right to work, study and vote in certain elections, as well as to access social welfare benefits and health services.
donaltroddyn··on Wikipedia Is Now a Brave Verified Publisher
Blockchain.com's privacy policy states that, for anti-money laundering purposes, they'll collect:

> Passport and/or national driver’s license or government-issued identification card to verify your identity

(from https://www.blockchain.com/legal/privacy). That's consistent with every other exchange I've used.

donaltroddyn··on No More Cheap Shipping for Chinese Sellers
Once the packages reach a domestic port, they still have to compete the same domestic journey as a local package.
donaltroddyn··on Startups from Y Combinator’s S19 Demo Day 1
Yes - agreed. I'm working on a product that started out as a a security SaaS, but has pivoted (using essentially the same technology) to an adtech product, because it is much easier to sell an increase in return on advertising spend than it is to sell a security product.
donaltroddyn··on British Airways passengers facing delays after IT failures
In most countries, there are severe penalties for airlines who allow passengers to reach destination immigration controls without valid documents, so if there's any doubt, airlines will not allow passengers to fly.
donaltroddyn··on Finnair Flight 915
Although Qantas has not had a fatal accident for ~70 years, it has a much smaller fleet and has had far more non-fatal incidents and accidents than Ryanair.

The real contender is Hawaiian Airlines, a ~90-year-old airline with no fatal accidents. Still, it's an order of magnitude smaller than Ryanair (~12,000,000 annual passengers).

donaltroddyn··on Finnair Flight 915
Surely Ryanair takes that crown, an airline which has never had a fatal accident, and which is an order of magnitude larger than Finnair (~130,000,000 passengers annually vs ~13,000,000).
donaltroddyn··on Equifax removed the $125 claim payout option after millions submitted claims
> In Europe, you as a private person just don't know it and don't have access to your own rating. But you are likely to be rated anyways..

In the E.U., there are no private organisations who can process your personal data without making it available to you on request.

In Ireland, there's a state-run Central Credit Register, to which lenders must submit any consumer credit agreement above €200, and which they must check by law before issuing credit. Anyone can apply online to get their credit history from the CCR, and make submissions to correct inaccuracies.

There's also the Irish Credit Bureau, a private organisation with a similar purpose. They are also required to reveal data held about you on request, and correct inaccurate data held.

donaltroddyn··on Implement mechanism to wait on any of several futexes
Not at all - it's a poor graph with an unlabelled axis.
donaltroddyn··on Capital One’s breach was inevitable, because we did nothing after Equifax
Agreed - it's turned out to be a privacy and security fiasco. Hopefully, the ICCL challenges will put an end to it.
donaltroddyn··on Capital One’s breach was inevitable, because we did nothing after Equifax
Ireland also does not have mandatory ID, nor do the Nordic countries. I don't think it's as clear cut as you make it out to be.
donaltroddyn··on Fujifilm’s first surveillance camera can read a license plate from 1km away
Depending on where you live, recording passing license plates could be very unlawful, and leave you open to significant penalties, so best to check before you set something like this up.
donaltroddyn··on New information about Slack’s 2015 security incident
Client-side hashing of passwords does not provide any of the benefits of server-side password hashing, as the client-side hash of the password effectively becomes the password, as it's all that's required to authenticate.

Client-side hashing does provide very limited protection against plaintext reuse (on other sites where the user uses the same password) in the case that it's leaked in transit, which is far less of a concern now that HTTPS is cheap and widespread.
