Sitter pÄ tÄget mellan Uppsala och Falun. Ska ta tvÄ timmar, kommer ta minst fyra. Har fÄtt nog av SJ. I fortsÀttningen blir det bil.
Uppdatering: Nu Àr jag i VÀsterÄs. Uppsala-Sala-VÀsterÄs-Avesta Krylbo-Falun: traveling salesman problemet, baklÀnges.
Uppdatering 2: Gick hemifrĂ„n kl. 08:05 i morse och kom “fram” till BorlĂ€nge(!) först kl. 12:52. FrĂ„n BorlĂ€nge fick jag skjuts. En planerad resa pĂ„ tvĂ„ timmar tog fem timmar. Bra jobbat SJ!
Uppdatering 3 (returresan): De hÀr gÄngen kom jag till Sala. DÀrifrÄn skulle det vara ersÀttningsbuss med en vÀntan pÄ 45 minuter innan avfÀrd. Det fick bli UL-buss för ytterligare 120 kronor frÄn Sala. Det hÀr Àr inget skÀmt. Det svenska tÄgsystemet Àr. (PS returresan var bokad i förvÀg.)
Birdcage liners
“Both Twitter and Facebookâs selfish algorithms, optimized solely for increasing the number of hours I spend on their services, are kind of destroying civil society at the same time. Researchers also discovered that the algorithms served to divide up the world into partisan groups. So even though I was following hundreds of people on social networks, I noticed that the political pieces which I saw were nevertheless directionally aligned with my own political beliefs. But to be honest they were much⊠shriller. Every day the Twitter told me about something that The Other Side did that was Outrageous and Awful (or, at least, this was reported), and everyone was screeching in sync and self-organizing in a lynch mob, and I would have to click LIKE or RETWEET just to feel like I had done something about it, but I hadnât actually done anything about it. I had just slacktivated.”
Google Mapsâs Moat â How far ahead of Apple Maps is Google Maps?
Interesting comparison between Google and Apple maps. Particularly fascinating is the analysis of how Google seems to be generating new features (data) by algorithmically analysing and combining aerial and streetview imagery (other data).
Hereâs a mystery: How did a nonexistent paper rack up hundreds of citations?
“Pieter Kroonenberg, an emeritus professor of statistics at Leiden University in The Netherlands, was puzzled when he tried to locate a paper about academic writing and discovered the article didnât exist. In fact, the journalâJournal of Science Communicationsâalso didnât exist.“

âSo, here is the irony: Toilets that are cleaned too often are more likely to be covered in fecal bacteriaâ (Yong, 2016, I contain multitudes).
Now that’s a dilemma!
The Absurdity of the Nobel Prizes in Science
“Every year, when Nobel Prizes are awarded in physics, chemistry, and physiology or medicine, critics note that they are an absurd and anachronistic way of recognizing scientists for their work. Instead of honoring science, they distort its nature, rewrite its history, and overlook many of its important contributors.“
What types of researchers are most likely to recycle text? The answers might surprise you – Retraction Watch
“Among Dutch historians we found virtually no text recycling. However, among Dutch psychologists text recycling is more elevated and among economists it is as much as one in seven publications. Text recycling also occurs more often among productive authors, in papers with fewer co-authors, and in journals that do not specify clear rules.“
