My lino block print portrait for prompt addition shows the amateur pioneering American scientist, inventor & women's rights advocate Eunice Newton Foote (1819-1888) who did the earliest experiments to show the insulating effect of certain gases & correctly concluded that increasing carbon dioxide levels would affect atmospheric temperature and climate, which we now call the Greenhouse Effect. 🧵

My linocut shows a Victorian woman in dress with apron and sleeves working at a table. She’s viewed from over her shoulder so you can only see her cheek and not her whole face. She has an open book in which she is writing. There is an air pump to one side and two large glass cylinders, each with two thermometers inside. She is printed in a gradient of pale blue at the bottom to bronze at the top on cream coloured washi paper. The numbered and signed print is titled “Eunice Newton Foote.”

The presentation of @pluralisticCory Doctorow - ah, let's call it a Brandrede - at the is really good. And, congratulations on that, is a rather positive one amidst rather dark times. In this speech we find recipes that should absolutely be tried out.

So if you initiate the phone-to-phone Signal account transfer process, and it almost completes, such that the account is transferred, but the data isn't, and then errors out ... and if you didn't have backups enabled ... then your entire chat history just vanishes* into thin air with zero recourse. In other words, Signal nukes your history from orbit on the old phone before validating that it actually successfully transferred to the new phone.

I am indescribably angry right now.

(The extra insurance you need, that I didn't have, was to enable general backups on the old phone first, and make sure that a backup completes on the old phone before initiating the transfer.)

Edit: kindly folks in my mentions are trying to explain that Signal wants to ensure that there is only ever one primary phone. The problem is that the risk of data loss due to the lack of confirmation of data transfer is well known enough to be in their troubleshooting guide (which, by the time you know you need it, is too late):

infosec.exchange/@tychotithonu

The user should be vigorously, repeatedly warned of the risk of data loss, right there in the transfer workflow, and strongly encouraged to make a backup prior to initiating the transfer.

* Edit 2: In the old phone, all history was visibly absent, immediately after the account was transferred. But now, after reboot of the old phone ... all of my message history is there?! But the backup option is gone, so I can't create a local backup in order to try to restore it. But at least all the history is still on the old phone? But there appears to be way to move it.

Common limitations 9. No recovery after failure * If transfer is interrupted and not completed, chat history may not be recoverable. * Consider enabling Secure Backups beforehand a a fallback.

Royce Williams (@tychotithonus@infosec.exchange)

Attached: 1 image @NormanDunbar@mastodon.scot Nice thought, but ... it turns out it's already a known issue, but it's buried in their troubleshooting, such that there'd be no reason for someone to look for it until it was already too late. https://support.signal.org/hc/en-us/articles/10075160307482-Troubleshooting-Device-Transfers @signalapp@mastodon.world

Your vote isn't won. It's predicted.

UK political parties collect and use data to profile you as a voter, tailoring their message accordingly.

Our investigation found that canvassing apps used by the Parties create risks to voters’ privacy.

Data profiling by political parties can put your privacy at risk and threaten electoral integrity.

But data protection hands power back to voters ✊

ORG has developed a tool for you to opt-out of data processing by the different UK political parties.

Take action ⬇️

action.openrightsgroup.org/opt

Opt-out of political parties processing your data

Political parties are hungry for sensitive personal data about your views, opinions, voting preferences and ideological outlook. Parties will actively seek to obtain this information from surveys and canvassing. They will also purchase commercially available data-sets and use automatic processing to try and predict your likely voting beliefs and intentions. Some people might be happy to volunteer this information to parties, or for political parties to purchase data about them.

關扣妮，中國東北鄂倫春族人，15歲重病不癒，依族內薩滿信仰請神，卻發現她被神選中為薩滿，關扣妮開始學習薩滿知識，病情開始好轉，最終成為一位薩滿。

1953年關扣妮「響應」新中國「破迷信」無神論思想，舉行「告別神靈」儀式，放棄薩滿身份。

薩滿信仰相信萬物有靈，薩滿是人與諸神的溝通管道。薩滿都放棄做薩滿，意味被視為迷信的薩滿信仰消亡。

2008年，關扣妮透過薩滿儀式，想將薩滿信仰傳承給女兒。但儀式並不順利，關扣妮多次摔倒，無法與神溝通，最後在現場攝影團隊暫避後，儀式終於結束，但降神沒有成功。關扣妮表示：

「（神說）妳為什麼叫我啊，為什麼這麼多年，你們都把我們丟了忘了……（神）三番兩次告訴她（關扣妮），（祂們）接受不了。」

進行傳承儀式的女兒在隔年因車禍逝世，原本不想進行傳承、卻被政府要求進行儀式的關扣妮十分自責痛心，她原本希望傳承能讓本有疾病的女兒也能因此痊癒，但神靈卻不願意來，儀式失敗。

關扣妮死後，鄂倫春族再也沒有薩滿。

——
一個離開神明、毀棄神明、消費神明的國家，是令人毛骨悚然的。如今無神的漠河市裡的鄂倫春民族博物館裡，還擺放著關扣妮事蹟，那是極其殘忍的悲劇。

Only in SF:

- bunch of explicitly anti-social, pro-AI ads show up
- people get mad
- ads had things like ‘you’re a bad parent. Just use AI to fix your kids before they go wrong’ and ‘replace humans’
- they revealed that this was all a joke to make a statement about irresponsible AI

(Phew, right?)

- it was an elaborate stunt by a startup that believes they are ‘responsible AI’ and others are not

(Check notes)

- said startup wants to replace receptionists with AI

Yes, It Was Us: Why Abby Launched a Campaign About the End of Humanity

When “Humanity Had a Good Run” appeared on billboards, people stopped and stared. Was it a threat? A joke? A protest? A few weeks later, another message appeared. This time, it was an AI app that claimed to replace human care itself: NurtureOS. It promised to help parents “calibrate their children.” It felt wrong. And […]
