stoneman24··on Surnames from nicknames nobody has any more
A while ago, my wife and I were invited to the Royal Garden Party at the Palace of Holyroodhouse in Edinburgh, in the presence of the late Queen. Very nice invitation in the form of Mr <me> and Mrs <me>.

As it was in recognition of my wife’s charitable works, She was not pleased at such a form of address. But we still went.

My favourite quote from Douglas Adams “ I love deadlines. I like the whooshing sound they make as they fly by.”
stoneman24··on Second-Hand Bookshops in Britain: 2024 Report
I think there are 2 factors which affect my success in finding books in charity shops.

what books are sold: I would like to understand the proportion of books sold by genre. Shops have a very high proportion of thrillers and crime novels.

likelihood of donation: Perhaps some fans are more likely to keep books than others. In my donations, thriller & crime books are donated first, I keep my SF.

This leads to a low chance of success in finding science fiction paperback for me. I guess SF (myself included) are just hoarders.....

stoneman24··on Markov Keyboard: keyboard layout that changes by Markov frequency (2019)
I think that this is an attempt to stop the “clean key” problem. Security system keypads (especially outdoor ones) tend not to be cleaned, so as time passes, it is easy to spot the dirty keys. Dirty keys are not being pressed and are therefore not in the passcode.

So look for the clean keys and try combinations from there. In a 4 digit (0-9) keypad, knowing the clean numbers drops the possible codes from 9999 to 24 (if my early morning math holds up).

Also helps the issue of someone looking over the shoulder of a valid person. Chances are they are just seeing the position and not the character pressed. So the keyboard changes and you actually need to know the character not just the old position.

stoneman24··on Starting a Business at 60: My Father's Story
While the decline is documented, there is much to be said for the more experienced employee. More knowledge about what is important in the domain rather than what might be the current fad.

In a competitive environment, certainly take advantage of your colleagues youth and inexperience.

The most problematic area is some people’s assumptions that you are too old to contribute. This might be misunderstanding or deliberate as they want less objections to their plans (or exploitations).

Being your boss might be an ideal solution.

stoneman24··on We can mine asteroids for space food
To extend D Rumsfeld

there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don't know we don't know.

And now things that we know and wish that we didn’t (ie spaceship recycling)

stoneman24··on We can mine asteroids for space food
Isn’t there a requirement for lots of fibre in the diet as well as vitamins, protein, carbohydrates and fats. As well as the psychological effect of eating good food and not mush.

How about “next favourite thing”
stoneman24··on A career-ending mistake
I agree that Managers/Directors should have a deep technical experience but having them contribute code to the day to day development is not a good situation for anyone (especially the companay).

There are some different aspects to this; The director will have many other responsibilities and may not be able to provide to provide the research/expertise required to produce a good code solution to the issue at hand and integrated with the rest of the system.

The rest of the project team may be delayed with waiting for the directors code and may well find it difficult to co-ordinate with the directors level of knowledge (which is perhaps out of date). In general, criticising the director for delay or bad code is not likely to be a career-enhancing path.

In small company/start-ups, this a common condition that does need to be remedied. Directors/managers have significant responsibilities that needs to come first rather than feed their own ego/desires. Hire good people and direct them to scale the business, your job is different now and you need all your skill/time/resources to do it well.

In short, personally been there a number of times and it wasn't good for anyone. But we struggled on.

stoneman24··on Biden Allows Ukraine to Strike Russia with Long-Range U.S. Missiles
Can’t really see nuclear war.

I think that Russia (Putin) thought that ukraine would collapse within days and it would be a walkover.

But it wasn’t and Zelensky bound his people together to resist the Russian army. The Russian army showed its capabilities and more surprisingly it’s huge limitations.

The oligarchy in Russia may well determine that getting rid of Putin might be less risky than letting him escalate the situation, especially if he starts talking about using even battlefield nukes.

stoneman24··on Biden Allows Ukraine to Strike Russia with Long-Range U.S. Missiles
Not sure how much additional real estate they can capture due to limited resources (especially manpower).

But this gives them a better chance of holding what they have and destroying the Russian logistics and infrastructure.

Hopefully the European powers and the UK will lift any restrictions that they have imposed and provide additional supplies.

stoneman24··on The different content TikTok and X showed an undecided voter
Perhaps AI might help us reach a calm consensus [0] But it’s seems to be very difficult to produce a AI without biases. So perhaps I am being very optimistic and we should just provide everybody with a Ground news subscription [1] that starts to highlight some of the biases.

stoneman24··on The different content TikTok and X showed an undecided voter
While free speech is fundamental right for all. I do wonder if we should question the different sources of our information feeds, more. Are they biased, slanted, too cautious, too reactive? Are they being poisoned by other actors to cause controversy? Are we just hearing those voices with the biggest megaphones…

Very easy to live in isolated bubble, not questioning our own little bubble. Ending up thinking one way, buying things, voting one way.

In questioning, we need to be critical but open minded and allow the possibility that we need to know to make the best decisions and opinions. But this takes time, research and concentration which are resources that are in short supply.

I try to raise my concerns in as neutral position as I can but it’s hard to avoid taking a partisan position on some of the headlines and media positions that I see.

stoneman24··on Optimizing Beer Glass Shapes to Minimize Heat Transfer – New Results
In addition to the interesting work done on heat transfer, i believe an important factor is the vertical height to base ratio. This would be simple proxy for the ease of tipping over. Some of the glasses considered are very tall in relation to their base diameter and expand in diameter towards the top of the glasses.

I’d go for the imperial pint glass, a very familiar shape and weight for me. Sample of 1 and I do live in Scotland where the ambient temperature rarely causes warming of the beer.

stoneman24··on NASA's Europa Clipper Launch
Not common but I have heard “moving at a fair clip” to describe speed in commentary and conversation.

Perhaps the term hasn’t quite died out.

stoneman24··on America's best-paid CEOs have the worst-paid employees
Looking at the utility value for the ceo and the employees. 10M for the ceo may make much difference to his lifestyle (slightly better yacht) but the $1000 for the lowest paid could make a big difference.

They just inhabit totally different financial landscapes.

stoneman24··on New anti-speeding system coming to Australia is dangerous
Driving significantly below the pasted speed Without good reason will get you failed in the UK driving test for not making adequate progress. As my office colleague found out recently.
stoneman24··on New anti-speeding system coming to Australia is dangerous
There is also many places where there are extremely few posted speed signs. The A9 in Scotland from Perth to Inverness is a notoriously dangerous road (it has large sections of single carriageway [60mph] with occasional dual carriage [70mph]). It has many junctions where cars can cross lanes to leave on minor roads. So bad, it has a large system of average speed cameras to hopefully control the traffic.

Driving slowly (40-50) on this long road will cause cars, buses and trucks to try and overtake even on the single carriageway sections which is risky for everybody.

But very few actual speed signs, so you end confused and wondering exactly what is the correct value for that section and anxious about the next average speed camera. And that’s for experienced uk drivers, I hate to think how stressed the tourists are ?

stoneman24··on A Scottish Provenance for the Altar Stone of Stonehenge
As a bit of a fan of Orkney (a family connection), I will point out that there are many attractions for archaeologists in Orkney. Some sites are dating before Stonehenge circle or at least similar timeframes, I wonder if the central Scottish stone at Stonehenge is an attempt to transfer the magic from Orkney (a biased view INAA)

We have the Standing Stones of Stenness (as mentioned), the Ring of Brodgar, the chambered cairn at Maeshowe, the Barnhouse Settlement and the Ring of Bookan. Also we have The Neolithic village at Skara Brae (The site was occupied from roughly 3180 BC to about 2500 BC and is Europe's most complete Neolithic village).

The archaeological dig at the Ness of Brodgar is closing soon after 20 years of work, to preserve the rest for future archaeologists. I think we have enough samples to keep the researchers happy for a long time.

If going then pack warm clothes as Orkney is very windy and frequently wet. To paraphrase Billy Connolly “Orkney is definitely windswept and interesting”

stoneman24··on Galois Theory
The ‘make thier own mental models’ vs sharing/providing full information is difficult.

‘Make thier own model’ of the domain can lead to deeper understanding but takes time and may lead to different (possibly incorrect) understanding of the issues and complexities. If not reviewed with others.

Providing full information upfront to a person can be quicker but lead to a superficial knowledge.

I think that it comes down to whether that deeper knowledge is directly needed for the main task. Can I get by with an superficial (leaky) abstraction and concentrate on the main job.

stoneman24··on Ask HN: Is there any software you only made for your own use but nobody else?
I agree, a blog post or other description would be great and really inspiring for my own projects.
stoneman24··on Analyzing my electricity consumption
Up in Orkney on vacation, the pretty constant wind all year (according to relatives) with a little solar, battery storage and heat pumps, I reckon off-grid might be possible. Add in starlink for internet and I might just stay here.

Not sure of the cost (need to do the research) but all of the above are getting cheaper. A small wind turbine can’t be that costly, surely.

stoneman24··on Agricultural drones are transforming rice farming in the Mekong River delta
In a recent episode of Countryfile [1](popular UK BBC1 program on the country and farming) the resident farmer was mentioning both crop rotation and the issue of black grass invading his wheat fields.

The black grass was slowly out competing his cash crop and would difficult to remove (perhaps taking the entire field out of any production for a year or the use of chemicals).

Having a horde of little robots might greatly assist in manually keeping other plants at bay without indiscriminately affecting the field with chemicals (extra one-use expense, robots would last many years).

stoneman24··on Everything about Mars is the worst (2017)
Wasn’t that convincing for me. The hard science elements seemed a bit cherry-picked and the later sections on governance and laws seem to want almost a wide spread agreement across multiple countries on every detail before people are allowed to go.

A multi-part review [1] is available which detailed more aspects quite well.

In short, people will go for a multitude of reasons (whether it is sensible or not).

stoneman24··on The secret D-Day scientists and engineers
I would agree and enjoyed reading the book, years ago.

If I remember correctly, good chapters on radar and radio navigation systems.

There was also details on the Me163 rocket plane which ran on the seemingly suicidal mix of concentrated hydrogen peroxide and hydrazine/methanol.

[edit] this was all long before we had the Wikipedia articles.

stoneman24··on 'I was misidentified as shoplifter by facial recognition tech'
The large Asda near me does this, too. Not happy about it but not sure what can be done to stop it. Probably needs either Scottish Parliament or Westminster to enact a privacy law and I can’t see that happening.

Perhaps it’s already covered under the European convention on human rights, but I don’t know if that still applies.

stoneman24··on The New 'Dream Chaser' Spacecraft Prepares to Visit the ISS
We also had the mustard space plane, back in the 60’s.

The idea/sketch is one thing but the actual engineering and funding is something else.

stoneman24··on Scotland suddenly has a lot of mosquitoes
Yep, lived for in Scotland over 50 years. The mosquito with its high pitched whine (so far for me) is rare, whereas the silent midge is hard to avoid in the summer/autumn.
