Kyiv

A drone one minute down the street, and a day's work carried on

Terry Yiu dropped his wife at her office in central Kyiv on Friday morning. An hour later the building a minute away was hit. By the evening he was posting about a rewrite of his app.

The most striking thing about Friday on this network was not that a Russian drone struck the Security Service headquarters in central Kyiv. It was who mentioned it, and how. Terry Yiu, a developer whose name reaches this page most often attached to a Bitcoin price app, wrote it up in four sentences with no adjectives in them.

An hour after dropping my wife off at her office, a Russian drone struck the Security Service headquarters one minute down the street. I could hear the explosion from home.

His wife, her team and her office are fine, he wrote. Several people were hospitalised and the restaurant next door was heavily damaged. He linked the Kyiv Independent's report of it — kyivindependent.com — and moved on.

Later in the day, asked why he is there at all, he answered without any of the defiance the question invites. My wife is Ukrainian, we have businesses here, and our child was just born here. Also, Kyiv is arguably one of the best cities in the world, even with the war ongoing.

And in between those two posts, the ordinary one. Yiu is on paternity leave and has spent it rebuilding his SatsPrice app, moving it off a hand-written Swift codebase he had found hard to maintain and onto Kotlin Multiplatform, which reaches iOS, Android, desktop and the web at once. He reports getting to near feature parity at ~10x the speed with Claude Code, and says he is only missing persisted currency preferences before he can release it.

A newspaper assembled by an algorithm would have filed those as three items. They are one. A man a mile from an explosion spent the rest of his day shipping software and thinking about a feature backlog, and both facts are true at the same time, and neither cancels the other.

Mining

Dashjr leaves OCEAN; hashrate down 96%

Luke Dashjr has left the mining pool OCEAN, and BTC Prague put the departure on the wire with the dates attached. Luke Dashjr is out at OCEAN. Resigned as chairman, CTO and director on 29 Aug. Mummolin repurchased all his equity.

The stated reason was differences over the future of Bitcoin mining, with nothing more specific offered. He is starting a new venture called CONVOY. The number that gives the story its weight is the one BTC Prague put last: OCEAN's hashrate fell 96% in August.

OCEAN's argument was always about template diversity — who chooses which transactions go into a block. A pool that has shed almost all of its hashrate is not making that argument to anybody. Nobody on this page had an answer to what happens next; the question was posted and left hanging.

The instrument

Six out of four hundred

Every edition is read twice: once through the reader's web of trust, and once with no lens at all, as a control. Friday's unranked read returned 400 notes. Six of them also appear in the 400 ranked ones.

A low overlap is the lens working, not failing. Ninety-eight and a half per cent of what an anonymous reader would have seen on Friday is not in this paper.

Money

Bitcoin below $80,000, and the jobs report did it

Bitcoin spent Thursday above $82,000 and Friday under $80,000. Bitcoin Magazine's account of it was blunt about the cause: Bitcoin slid Friday after a better-than-expected labor report showed that the U.S. job market accelerated in August. The low of the New York morning was $78,706.

The mechanism is the boring one. A strong labour market makes a rate rise likelier, and traders now put the odds of a hike at the Federal Reserve's September 15–16 meeting at somewhere between half and three-fifths. The new Fed chair, Kevin Warsh, said last week he had more work to do on inflation.

The President disagreed, on Friday, in capitals. We should have the LOWEST RATE of any country in the World, like 'the old days.'

A year of going backwards

ChartsBTC, which posts the same measurements every day and lets them speak, filed the one that stings. The one-year price multiple stands at 0.73: $81,315 against $110,747 twelve months ago.

The holder data cuts the other way. Coins that have not moved since 2022 or earlier now account for 8.05M BTC, just over forty per cent of supply. Whatever the year did to the price, it did not shake much loose.

Security

Another 67,000 Trezor customers, and the assurances were worthless

A breach announced last month turns out to be six times larger. The data was meant to have been deleted five years ago.

Trezor said on Friday that a further 67,000 US customers had names, emails, phone numbers, shipping addresses and order numbers exposed — orders placed between November 2019 and August 2021. The original disclosure in August covered 11,742 customers across seven countries. A further 1,947 people had names, cities and emails taken.

The leak did not come from Trezor. It came from ShipMonk, the fulfilment partner that held the orders, and the company's statement is the sound of a contract failing:

Throughout our entire relationship with ShipMonk, we repeatedly requested and received written assurance confirming the deletion of the data, in line with our contract, data policy, and past communications,

followed by: We are very disappointed that, despite receiving this confirmation, the data was not deleted in their systems. A hardware wallet's threat model does not usually include the courier's database, and a list of people who bought one, with their home addresses, is a shopping list.

The month it lands in was already bad. Bitcoin Well, reporting its August, opened with the industry's number rather than its own: Well over $100 million walked out of hardware wallets and Lightning nodes in a few weeks.

And in software, Zapstore asked everyone to update, having found the kind of bug that does not announce itself: It was released last week and contains a fix for a major security bug found in an underlying library, related to nostr event verification. The maintainer credited the finder, could not locate their profile to thank them properly, and said they deserved zaps.

The Network

Nostr spent Friday arguing about whether it is dying

It resolved, roughly, that it is not. The argument ran across a dozen accounts who were mostly not talking to each other, which is the sort of thing this page exists to notice.

fiatjaf set the high-water mark for confidence, and it is impossible to tell how much of it is a joke: This day will be remembered for many centuries as the day in which Nostr reached its bottom and started to climb up after its last final flaw was finally eliminated. Two hours later, on the fix itself: The fix was handcoded.

Anders had been saying something similar all week in a plainer register — Nostr going through a big rotation. People and tools. Have got a lot of interaction last couple of weeks. New connections. Car put it in terms of who is in the room: I'm seeing more people I don't recognize lately, which is probably why it's starting to feel fun again. Early Nostr, they added, had that weird mix of people figuring it out together.

Marius made the case that the malaise was never local to this network at all — that it is a consequence of ai, (same) memes, bots, and algols that has destroyed the integrity of short messaging apps, and that books and long podcasts still work. Reed's version was the shortest and the best: Nostr isn't dying, it's users are just healing.

Meanwhile, the bots

On the same day, Anders flagged something less cheerful: Some sort of bot account. Seen a few today. Might be a fud attack.

By the evening fiatjaf was asking the maintainer of the web-of-trust relay for a lever to pull. wot-relay needs a way to manually ban bots that surreptitiously infiltrate the WoT. Reacting to a kind:1984 report event by the owner is probably the best way.

This page is ranked by exactly that machinery, so the reader should know: the thing that chose these stories is the thing being patched.

Two lines about specifications

hodlbod, at just before one in the morning: Don't vibe specs, kids. fiatjaf, two hours later, apparently unable to leave it alone: Vibe: kids don't spec.

Asked, not answered

fractalchris put a question to the room and got the usual thicket of preferences back. Any idea what are the best, most secure and private messaging apps these days? — asked, they stressed, on technical grounds rather than taste.

A poll from utxo the webmaster went at the same nerve from the other side: Could you run your entire life stack on open source? What closed source stuff could you not live without?

The Workshop

A mesh network that uses your keys as your address

FIPS reached v0.5.0 on Friday, and the clearest description of what it does came from Johnathan Corgan, who wrote it out for somebody who had asked.

In short, running FIPS lets your system join a mesh of other FIPS nodes, gives you a new IP address, and lets you communicate over the mesh with any other FIPS node. There is no domain, no routing configuration, no firewall or NAT configuration, etc. No permission needed.

The best advertisement was somebody using it for something dull. notmandatory reported sshing into a home machine stranded behind a carrier NAT: With FIPS I'm able to assign my home server a self generated npub and talk to it from anywhere. This is how the internet is meant to be, peer to peer, private and permissionless. They apologised for running a personal VPN over the project's test net, and offered the traffic as load testing.

The release notes

Amber 6.6.1 — the Android signer fixed a parsing bug where a permission entry with no kind field could take down the whole permission list, and another where a rejected request came back without its id, leaving the calling app unable to match the refusal to anything.

Mostro v0.18.7 — the peer-to-peer trading node capped in-flight payouts per destination and node-wide, so one destination can no longer tie up a node's liquidity, and cut the ceiling on user payout invoices from 432 blocks to 144. Mostro Mobile v1.4.2 landed the same day with a fix for a missing release button.

TWENTY ONE Companion v1.11.0 — moderation moved onto the phone, including a timed suspension as an alternative to removing somebody outright.

Zapstore 1.1.2 — see Security, above, and update.

Also filed: Ditto, NoorNote, Imwald for Android, FitBook, a Casio G-Shock sync tool, and UnstableKraft, a podcast aggregator that keeps paid feeds on the device.

Books & Ideas

A man spent Friday underlining an essay from 1945, and it was about this

Gigi, who reads with a highlighter, marked more than thirty passages on Friday. A dozen of them come from one essay: Vannevar Bush's As We May Think, published in The Atlantic in July 1945 — the piece that imagined the memex, and with it more or less everything since.

Bush's prophecies are funny now in the way only accurate ones are. On the wearable camera: The camera hound of the future wears on his forehead a lump a little larger than a walnut.

But the passage Gigi kept circling back to is not about hardware. It is about the job of finding things worth reading:

There is a new profession of trail blazers, those who find delight in the task of establishing useful trails through the enormous mass of the common record

Bush's worry was that good work vanishes for want of a reader. Mendel's concept of the laws of genetics was lost to the world for a generation because his publication did not reach the few who were capable of grasping and extending it, he wrote. His warning against expecting too much of the machine has aged just as well: For mature thought there is no mechanical substitute.

Gigi spent the rest of the day in more recent company. From Joan Westenberg's essay on the third brain, two marks: The mind leaks outward - and it always has. Writing, numbering systems, and maps are not external aids to thought; they're components of thought itself. — and, on what happens when you let the machine do the thinking, the phrase depressed middle managers servicing an algorithm.

The reader will notice that a paper assembled by following one person's trail through a day's record, and printed for that person alone, has spent a column on an essay about exactly that. The editor noticed too.

Against the pocket computer

The same reader marked a line from Ploum's argument for not owning a smartphone, published this week: "I don't have a smartphone" is, according to my experience, the easiest explanation, the shortest way to force people to get their shit together.

And from the offpunk manifesto, a sentence that would have been science fiction when Bush was writing: we no longer connect to the internet. We simply live in it.

One to read

Trey, writing about what a high salary hides in a K-shaped economy: Asset prices can respond before wages do, which rewards people who already own scarce or productive assets and leaves cash-heavy savers absorbing more of the purchasing-power loss.

Arts

One of four images filed with Loki's note about Gustav Klimt and the survival of his paintings.
One of four pictures Loki attached to a long note on Klimt, whose work was plundered and traded under the Nazi regime and came through it largely intact.Filed by Loki

The degenerate who outlasted them

Loki's subject was Gustav Klimt, and the argument was that his paintings survived a regime that should have destroyed them — despite the eroticism, despite the patronage of Vienna's wealthy Jewish community — because the people doing the burning wanted these particular pictures for themselves.

The detail that carries the note is about Hermann Göring, who had traded 137 lesser paintings for a Vermeer and, when told it was a forgery painted in 1937, was reported to have looked as though he had encountered evil for the first time.

On the money, Loki is dry: Though money is a crass way of looking at it, his paintings are among some of the most valuable in the world now — Lady with a Fan went to a Hong Kong collector for over $100 million, the Portrait of Elisabeth Lederer for around $250 million.

Their own verdict on the work is refreshingly unimpressed: reasonable to look at and reflect over, nothing special. What moves them is the route the paintings took to get here — of families split apart and of people living in the margins of history books.

Gardens & Kitchens

Posted to the #coffeechain tag, which is where a good deal of this network's actual daily life happens.

Four winters of hauling water

Off Grid Homestead, asked what the hardest part was, did not say the building. the worst was hauling water the first 4 years. That really sucked in the middle of winter.

The routine was a cage tank in the truck, a half-hour drive, a pump and a generator, every weekend, both ways. We finally had a well drilled a couple years ago, that my friend was a game changer. They still work a full-time job; the tinctures and the food do not cover it.

Friday's task was tomatoes to can and a garden to put to bed for the winter.
