You don't even have green, grey or blue eyes, or red, blonde or golden hair (all mutations from the Fair Folk)?

Only for Aés Sidhe or other Celtic fairy folk that are noble (AKA high lords). They are only mere doors for mundane humans.

The sane way for social housing is the State borrowing, building and then owning.
An "investor" wants profit and likely pays more to borrow than a Government.
Thatcher was crazy.
See also the stupidity of toll roads, tunnels and bridges here in Ireland where significant funds are lost in cost of collecting the toll and the Private partner makes a profit. Abolish tolls and "car tax" and simply tax the fuel, which is over 60% tax anyway here. Fairer too.

The original "dry" Zinc Carbon cell invented by Hellsen? Sweden & copy patented in USA by a UK Chemist.
The American Novelty company bought that and sold electric torches to NYPD, but no depolariser, so quickly dimmed. Flashlight.
They became NCC / Ever Ready.
Original Zinc cells (1900) were wet and open top!. Telegraph use from 1831.

Duracell is interesting, though other companies may now be higher quality.
Starts 1920s by work of Samuel Ruben and Philip Mallory, and the formation of the P. R. Mallory Company.
Mallory developed the mercury cell and invented the button/coin package, used since 1930s.
Eveready developed the Alkaline cell, but decided it was too expensive & Mallory licenced it.
Approx 1968 the UK stopped UK Ever Ready (spilt off 1908) buying Mallory, which became Duracell.

Successes since 1950s:
Mercury buttons (1930s) > Alkaline. Silver Oxide, Zinc Air & Lithium depending on application.
NiCd (1940s) > NiMH. Sometimes better than Lithium Ion. > Lithium Ion
Lead Acid > Lithium Ion > LiFePO4, but not for engine starters. SLA/Gel now entirely replaceable LiFePO4.
Zinc Carbon (1880s) > Alkaline > Zinc Air (hearing aids & Cattle Fencers).
Large Lithium Ion > LiFePO4
The LiFePO4 is still improving, safer, still dropping in price. Maybe 15 year life!

The actual article rather than the breathless Yahoo.

Except it doesn't tell us much.
Except in small portable things, Lithium Ion isn't used now. Solar and EV use Lithium Iron Phosphate which has a very low risk and less toxic production / materials.
Periodically there have been announcements of better batteries in the last 80 years. Some have become reality.

The difference is most working AI code is stolen and most of it is very poor or doesn't work.
A real human programmer (not a code monkey) will help you analyse your requirements, write a specification, do a design, code it (write the program, implementation) and test it.
While keeping you in the loop.
LLM/Generative AI is mis-sold. A scam and a technological dead end. The model collapses when it scrapes its own outputs.

I learned C++ after Modula-2 and before C.
I learned programming earlier.
Learning a programming language isn't learning programming (extracting requirements, specification, design, coding, test etc).
I looked at Rust. C++ certainly has got too complicated since 1987, but I wonder does Rust *only* help with memory safety?
Main memory safety in general relates to using pointers that are invalid, accessing arrays out of bounds and past the end of strings.
Partly bad libraries & design.

A compiler implements it. The LLM/Gen is a rubbish search engine, database and statistical engine. It regurgitates based on prompts, not formal specifications.

"make wonderful, creative, unique software using AI."
No. An LLM can't create at all and if it actually works and meets the spec it's likely copied.

NO, the article isn't about powering up SSDs, but they fade in a drawer.
It's proven that HDDs generally don't wear out when powered off. The bearings etc only degrade when they are spinning.
The big plus on SSDs is random access speed, not reliability, for a home user. They are not a backup medium. An SSD in an external USB box is useful for file transfer, not backups.

2026-02-06 21:37:39 UTC

- reply

There are no ideal options for SSD. That's why I have backups and the user data on my workstations and main laptop is on HDD (conventional, not shingled or helium etc). The OS is easily installed and restored from backup on a new SSD.
The point is that an unused conventional HDD will last for decades. That's unlikely for SSDs or any high capacity SD card, USB stick etc.

Not powered off they don't.
An HDD can wear out with use but 25 years is easy for storage in a drawer or box in the attic. Floppy storage is far trickier.
Tape needs carefully stored.
Pressed DVDs* and especially pressed CDs are OK, but "written" ones can fade in daylight.

It's tax payer subsidy of air travel, indirectly. Jet fuel isn't taxed, but in most of Europe the train fuel is taxes. Electric trains are a more complicated issue.
UK tried privatising the rail systems and that made everything worse.
Aircraft fuel needs to be taxed equally, everywhere.

The PCs come with Windows.
It's not about Linux. People will only switch if MS makes Windows totally unuseable.
But businesses are being hostage by about a dozen companies that only write Windows Software, and often in the last 30 years have done it badly.

I think Chaucer is old, but maybe Middle English.
I suspect it's 18th C. Scots' Dialect. Not many people can read Robbie Burns either.
Oh!

And some wad eat that want it;
But we hae meat, and we can eat,

18th C. Address to a Haggis
https://en.wikipedia.org/wiki/Address_to_a_Haggis
Chaucer was 14th C.
Old English, in the strict technical sense is 5th C. to 12th C.
I had difficulty finding examples of 16th C.

‘Ye’ll sit on his white hause-bane,
And I’ll pike out his bonny blue een;
Wi ae lock o his gowden hair,
We’ll theek our nest when it grows bare.
‘Mony an ane for him makes mane,
But nane sall ken whare he is gane;
Oer his white banes, when they are bare,
The wind sall blaw for evermair.’

As I was walking all alane,
I heard twa corbies making a mane;
The tane unto the t’other say,
‘Where sall we gang and dine the day?’
‘In behind yon auld fail dyke,
I wot there lies a new slain knight;
And naebody kens that he lies there,
But his hawk, his hound, and his lady fair.
‘His hound is to the hunting gane,
His hawk to fetch the wild-fowl hame,
His lady’s ta’en another mate,
So we may make our dinner sweet.

Visa & Mastercard can't sue.
There is already IBAN (free online transfer in EU), which even works in USA, and other funds transfers apart from PayPal and Western Union.
"13 of the 20 countries in the euro, including Ireland, have no domestic card scheme. You use an international operator, or you pay in cash."
It's alternative to Revolut (can be cardless), PayPal, Apple, Google, Amazon or clunky IBAN (which is only online), not Visa/Mastercard USA Credit or debit cards.

The problem with aviation fuel tax is partly everyone needs to do it.
Remove / refund fuel tax (and road tax?) on all public transport and since competition on that is senseless have only one rail operator and one bus operator, that may or may not be state owned.
See also the waste of mobile radio spectrum by not having one wholesale operator.
Abolish tolls (Ireland) and road tax but put up tax on fuel. Local congestion / pollution taxes need to stay.

Libertarian (nothing to do with Liberal) and Right Wing since Regan / Thatcher is about freedom, and a level playing field for own national, for large Corporations. About making the top 1% richer. Not personal freedom.
Trickle down economics is the lie that justifies it.
So it's the philosophy to outsource everything. Not to have a single State ownership for strategic resources that really there is only one of. Not to have capital expenditure on housing, schools, hospitals etc.
