Lotus's decision in the 1980s to convert its DOS products to OS2 rather than Windows, little remembered today, was one of the truly catastrophic mistakes in modern IT history. Lotus opened the door wide for Excel and Word, and relegated itself to the dustbin of history.

Keir Starmer tells his Cabinet that scenes of police under attack at a march "led by a convicted criminal and egged on by a foreign billionaire calling for violence" sent "a chill through the spines" of British people.

In good but unexpected email news, the widow of the late Robert Mugabe has cherry-picked me to manage $87,500,000 in investment funds.

Reform UK further enhance their image as the party of ordinary people by welcoming Danny Kruger, the Eton/Oxford educated son of multi millionaire parents.

Earth science departments are being gutted across the country, which is utterly bizarre given their relevance to our understanding of climate, hazards and disasters, the soils that feed us, the industries that drive our economies, and the importance of ancient life to understanding biodiversity.

He used the word "la giologia" - geology - for the very first time in 1603, describing it as "the study of all things related to Earth."

If you vote Reform you will be voting against women’s equality, for more harassment in the workplace and beyond (as if there isn’t enough)

Remember 41% of the Farage Foot Soldiers arrested in last summer’s disgraceful riots had already been REPORTED FOR DOMESTIC ABUSE

Ten fish fingers in a box is stupid. It should be at least 12. Easy divisible by two, three or four. Ten is only divisible by two or five

If these people are filmed or seen by the police painting flags kn roads etc can we expect police to investigate and prosecute, as was done with PA when they painted a few planes? Surely their ideology - and we all know it's not just innocent patriotism - makes them more of a threat?

All these right wing patriots fervently putting flags up everywhere seems somehow familiar...

Geology of Milan-Sanremo | Geo-Sports We explore the geology of Milan-Sanremo with lost oceans, colliding continents plus a bit of risotto and wine.

So, some background for the start of @lavuelta.bsky.social…and oddly, the best way to do that is by telling you about the geology of Milano-San Remo 😃. The first days will be about the Po Plain and the Ligurian Alps! Enjoy!
