Greenland ice cap melt inevitable sea levels may rise 27cm
31 August 2022
We’re passed the time for warnings… a significant increase in sea levels is unavoidable, with the melting of the Greenland ice cap expected to add twenty-seven centimetres to global ocean tidemarks. It could be a whole lot more if (or when) other ice masses melt:
Major sea-level rise from the melting of the Greenland ice cap is now inevitable, scientists have found, even if the fossil fuel burning that is driving the climate crisis were to end overnight. The research shows the global heating to date will cause an absolute minimum sea-level rise of 27cm (10.6in) from Greenland alone as 110tn tonnes of ice melt. With continued carbon emissions, the melting of other ice caps and thermal expansion of the ocean, a multi-metre sea-level rise appears likely.

Video of a solar eclipse on Mars, Phobos occults the Sun
30 August 2022
Footage of a solar eclipse on Mars, filmed by NASA roving probe Curiosity. Eclipses on Mars are a little different to those we are treated to on Earth though, with the speed of the red planet’s “moontatoes” making the phenomenon more of a blink and you’ll miss it occasion.
Mars’ moons Phobos (“fear” in Ancient Greek) and Deimos (“dread”) circle Mars every 7.65 and 30.35 hours respectively, a relative blink compared to the 27-day orbit of Earth’s moon. They’re also a lot smaller than the Moon, and considerably more lumpy – little moontatoes, rather than the nice round disk we see shining so argently in our night sky.
It makes me think. If Pluto doesn’t make the grade as a “proper” planet, why should the so-called satellites of Mars be regarded as moons? Surely “captured objects” would be a more apt classification.

Albertina Museum makes thousands of digitised artworks available
30 August 2022
The Albertina Museum, in Vienna, capital of Austria, has released some 150,000 digitised images into the public domain. This will be a boon for anyone with an interest in European history and art, or both. Some of the images now freely available include works by Edvard Munch, featured above, who is best known for his painting The Scream, along with Albrecht Dürer, and Gustav Klimt, among others.
Nearly 4,000 of these images date between the 12th and 15th centuries, with another 23,000 dating to the 16th century. The Albertina has a large collection of works by Albrecht Dürer (1471-1528), a German artist who was famous for his woodcut prints and a variety of other works.

Bicycles and the damage they have caused by Paul Fairie
29 August 2022
Paul Fairie, a researcher at the University of Calgary, and humourist, has, based upon clippings from vintage newspapers, concluded that bicycles are responsible for all sorts of problems:
- A decline in marriages
- A decline in book sales
- Appendicitis
- A decline in furniture sales
- An increase in the number of women smokers
- A decline in grain consumption
- The closure of a Christian society (so now we know…)
- The decline in trans-Atlantic travel
- A condition referred to as “bicycle face”
Bicycle face, in case you’re curious, is described as being “the sentimental side of that tired feeling”. It possibly also applies to cyclists riding on a footpath (especially when a dedicated bike lane runs adjacent to the same road), who look passed pedestrians as though they are invisible.

The value of tsundoku, the value of book hoarding
29 August 2022
Tsundoku is the word of the day. It is a Japanese portmanteau from the nineteenth century, describing the accumulation of books that will never be read. Great stacks of books lying around the house, waiting to be read. Already the thought grates against my minimalist sensibilities.
As American journalist and writer Clive Thompson explains though, all these books — gathering dust as they may be — are a great way to remind ourselves of the stockpile of knowledge in the world. Maybe there are days when it’s easy to believe we know all there is to know. Those same books, sitting there still unread, still gathering dust, which Thompson refers to as an antilibrary, serve to inform us we cannot know it all.
The other part of an antilibrary, though, is that it makes you constantly aware that you could explore more things. By having all those books lying around unread, they trigger curiosity.
All I can think of is trying to move house with a half a library worth of books. I once helped someone in that situation, and all I can say is: never again. I might keep to wandering among the shelves of my local library, when it comes to appreciating how much there is to know in the world.

Cars with manual transmissions are becoming fewer and fewer
27 August 2022
Cars with manual transmissions are sadly going the way of the dodo… but who am I to complain, so is working from an office block for many people.
I learned to drive in a manual, though I did my first drive in an automatic, around an empty shopping centre parking lot one Sunday afternoon. At one point I could change gears on a manual without using the clutch, it was quite easy once you knew what to do.
As Matt Crisara writes for Popular Mechanics though, automatic transmission vehicles are becoming better, and, really, manuals are quite needless.
Being able to drive a manual car is about so much more than the simple joy of being in control of a machine. Most of my sense of accomplishment came from navigating the steep curve of learning how to drive a stick shift with my dad at my side — it’s not something you master overnight. I’m not ashamed to mention that it took me a few sessions in a parking lot to get the fundamentals down. Now, fewer kids are going to have this chance as manuals become harder and harder to find.

Peiter Zatko’s whistleblowing Twitter report may not help Musk
27 August 2022
Earlier this week a whistleblower complaint to the United States Congress made by Peiter Zatko, who was head of security at Twitter until his departure in January, was made public. Some commentators saw Zatko’s report as a damning insight to the management of the social media service, which supported Elon Musk’s decision to abandon his takeover bid for the social networking service:
The disclosure, sent last month to Congress and federal agencies, paints a picture of a chaotic and reckless environment at a mismanaged company that allows too many of its staff access to the platform’s central controls and most sensitive information without adequate oversight. It also alleges that some of the company’s senior-most executives have been trying to cover up Twitter’s serious vulnerabilities, and that one or more current employees may be working for a foreign intelligence service.
Mike Masnick, writing for Techdirt, in a detailed analysis of Zatko’s complaint, suggests the report in fact backs Twitter’s position, and may not be the legal leg-up Musk is seeking. Musk, who claims Twitter did not reveal the true extent of spam accounts on the platform, launched legal proceedings against the company in July.
But, as Masnick points out, Musk’s lawsuit has nothing to do with spam accounts on Twitter:
The first and most important thing to remember is that, even as Musk insists otherwise, the Twitter lawsuit is not about spam. It just is not. I’m not going to repeat everything in that earlier story explaining why not, so if you haven’t read that yet, please do. But the core of it is that Musk needed an escape hatch from the deal he didn’t want to consummate and the best his lawyers could come up with was to claim that Twitter was being misleading in its SEC reporting regarding spam. (As an aside, there is very strong evidence that Musk didn’t care at all about the SEC filings until he suddenly needed an escape hatch, and certainly didn’t rely on them).
Musk insists Twitter claimed only five-percent of accounts on the platform were spam or fake. But the five-percent number derives from so-called mDAU accounts, being monetizable daily average users, which Twitter defines as a “valid user account that might click through ads and actually buy a product”. The mDAU accounts sound like a rarefied group of members, but the spam count only applied to them, not the platform as a whole.
Except it’s Musk here who is using clever wordplay to distract and mislead everyone. As we’ve described over and over again, the 5% number that Musk repeats in these screenshots is about mDAU. The 5% number is what Twitter reports is the amount of spam they believe incorrectly gets counted in mDAU. It’s Musk who keeps pretending the 5% number implies spam across the entire platform, which Twitter has never said it does. As we’ve explained multiple times now, Musk is trying to distract by pretending that the 5% claim is about spam on the entire platform. It never has been. It has always been an estimate of the amount that makes it through and is still counted in the mDAU. That is clear to anyone who’s actually read Twitter’s filing (both in the Chancery Court and at the SEC).
Masnick’s article is a longer piece, but well worth the read for anyone with an interest in Musk vs Twitter.

From woe to go Triple J ratings rebound in latest survey
26 August 2022
Last time I wrote about listener survey ratings for local and alternative music Australian radio station, Triple J, the news was not good for the broadcaster. Results of survey four for 2022, conducted between Sunday 22 May and Saturday 25 June, and released on Tuesday 5 July, showed a sharp fall in the number of people tuning in.
The findings of survey five though, where radio listeners were polled between Sunday 10 July and Saturday 13 August, revealed a jump in audience numbers, among Sydneysiders aged 18 to 24.
Australia’s national youth broadcaster Triple J has seen a noticeable bump in its key 18-24 demographic in the fifth radio survey of the year, after struggling with its core audience in Sydney for most of 2022. The latest survey has seen the broadcaster more than double its 18-24 audience share, leaping from 4.4 per cent to 9.6 per cent of all listeners in that age group.
Despite the overall increase of listeners in the 18-24 demographic, Triple J’s breakfast and morning shows saw a decrease in audience numbers.
