iOS Dev Course Going Out of Business

21 October 2026 at 19:33

Sean Allen (via Rebecca Sloane):

iOS dev course sales plummeted due to AI. It costs a lot of money to host my courses online and with sales at basically $0, I’ve cancelled that hosting.

This closes down the site which unfortunately removes access to the courses.

[…]

I’ve put my recent course on sale at a large discount so you can get it before it’s gone and I’ve made old courses available for free if you want to grab those too.

The school will be online until November 24th so you have a few weeks to download these videos at seanallen.teachable.com.

Review: Carrie is a triumphant remix with one major flaw

21 October 2026 at 12:19

Carrie White, the telekinetic prom queen from hell, is one of the most beloved horror icons in popular culture. First introduced in Stephen King's 1974 novel, Carrie, the character was immortalized in director Brian De Palma's 1976 adaptation, widely regarded as one of the best horror films of all time. It's certainly one of the best King adaptations. So Mike Flanagan faced a massive challenge when he signed on to create an eight-episode miniseries for Prime Video based on the book, released just in time to mark the 50th anniversary of de Palma's film.

I was among the skeptics who questioned why a Carrie miniseries was even necessary, although as a diehard Flanagan fan ("Flana-fan"?), I was willing to give him the benefit of the doubt. If anyone has an affinity for smartly adapting horror in general, and King's work in particular, it's Flanagan. And you know what? With one (very big) exception, Flanagan pulls it off, giving us a richly textured version of the story that is as much about kindness and lost innocence as bloody, vengeful rage—although we get plenty of the latter, too.

(Many spoilers below for the novel and the 1976 film, but there are no major reveals for the new series until after the second gallery. We'll give you a heads-up when we get there.)

AI disqualification yields new Nikon Small World in Motion winner

Last month we covered the winner of Nikon's Small World in Motion video: Ning Xu of Tsinghua University in China, whose video captured tiny cilia beating in the airways of a child with a rare respiratory disorder. But allegations surfaced about Xu's use of AI while making the video. Nikon launched an investigation and concluded that Xu's entry did not comply with competition rules. The new winner is Nguyen Nam Nhat of Vietnam with a video of a tiny roundworm and a single-celled organism (above).

According to a BBC report, some researchers expressed concern that Xu's video had structural abnormalities and that cell features appeared and disappeared in a way one would not see in actual cellular biology. Others spotted what looked like AI watermarks embedded within the source files. Xu said he used AI “to distinguish and visualize features in the reconstructed grayscale images”; however, he denied that AI was used "to generate the experimental movie, the cilia, or their motion.”

Founded in 2011, the Nikon Small World in Motion competition is a spinoff of the company’s Small World Photomicrography Competition, which has been around since 1974. Both are meant “to showcase the beauty and complexity of things seen through the light microscope”—one through still photographs, the other through photovideography, taking advantage of all the technological advances that now allow users to make movies or time-lapse images through the microscope.

The other winners also moved up a notch with Xu's disqualification. Benedikt Pleyer of Bavaria, Germany, placed second with a video of jellyfish larvae suspended in water droplets; Andrew Moore of Howard Hughes Medical Institute in the US placed third with a video of synchronized cell division in neighboring cells; Patrick Hickey of Hypha Research Ltd. in Edinburgh, Scotland, placed fourth with a video of the dynamics of mitochondria and chloroplasts in Turtle Vine leaf cells; and Igor Adameyko placed fifth with a video of a tiny, colorful sea slug (Cyerce kikutarobabai) on the move.

Margaret Hamilton, RIP

8 October 2026 at 16:21

Janine Liberty (Hacker News, NASA, NYT, WSJ, Slashdot):

Margaret Hamilton, a profoundly influential computer scientist best known for leading the software engineering team at MIT’s Instrumentation Lab during NASA’s Apollo program, died on Sep. 30. She was 90.

A computing pioneer who authored over 130 publications, Hamilton helped to establish software engineering as a dedicated discipline.

[…]

Moments before the Eagle module was set to land on the lunar surface, the onboard computer raised the alarm. It had detected a 1202 error: The computer was overloaded due to a fault in a hardware switch, and it was possible the system would not be able to handle the complex landing procedure.

But Hamilton and her team had engineered priority-driven software, able to shut down unnecessary background tasks in order to prioritize mission-critical tasks. Houston trusted Hamilton’s software and allowed the mission to proceed, and two men walked on the moon for the first time.

Dave DeGraw:

The following is an excerpt from a textbook called Fluency With Information Technology: Skills, Concepts, & Capabilities, 7th Edition ISBN 0-13-444872-3

At the time of publishing, the Wikipedia page for Margaret Hamilton has an important quote about the origin of the term “software engineering”. I was moved by this and wanted to add it to my /quotes page, but needed to verify the source of the quote. I was bothered that the source came from an interview given for an out-of-print textbook that as far as I can tell is unavailable to legally obtain. The interview is also not published in later editions of the book.

Fortunately, I was able to find the complete interview and I am publishing that excerpt here under fair use doctrine for educational, archival, and personal informational purposes only.

The Computer History Museum has an article and a full oral history.

Previously:

Update (2026-10-14): Jennifer Ouellette:

You’ve probably heard the famous story of how Lorenz kept a continuous simulation running on his LGP-30 computer, and of that fateful 1961 day when he realized that even small differences in starting values could lead to very different outcomes—a sensitivity to initial conditions that is a hallmark of chaos theory, along with strange attractors. You might not have known that it was Hamilton who was responsible for programming the LGP-30.

Computers were still a novelty at the time, and neither Lorenz nor Hamilton had any programming knowledge; they taught themselves. Per a 2019 Quanta article, Lorenz was amused by her unusual methods: For instance, she once bypassed the “clunky debugging process” by rolling the paper tape down the hallway and editing the binary code by hand with a pencil. “I’d poke holes for ones, and I’d cover up with Scotch tape the others,” she recalled.

The Unreasonable Effectiveness of Constructive Data Modeling

7 October 2026 at 19:47

Alexis King (tweet):

The type systems provided by mainstream languages have grown vastly more sophisticated, but how much value does that complexity actually provide programmers in practice? I would like to make the case that it is somewhat less than one might think. While at times convenient, invariants can be captured in the type system using a small set of simple tools applied in principled fashion, and while fancy type systems may be convenient, they have misled many programmers by obscuring what is possible to model without built-in type system support. This talk aims to provide a simple shift in perspective, plus a set of concrete design principles, to make modeling invariants in types feel accessible to the working programmer without fancy language support.

“Type system as obligation tracker” is a catchy phrase, like her previous “parse, don’t validate” (Hacker News).

Unboxings do iPhone Duo vazam antes da hora; veja os primeiros reviews

21 October 2026 at 15:08

Se você rolou pelos feeds das principais redes sociais na manhã de hoje, percebeu que já começaram a pintar os primeiros reviews do iPhone Duo, cujo lançamento ocorrerá nesta sexta-feira (23/10).

Horas antes de o embargo cair, contudo, uma série de vídeos de unboxing e hands-on começaram a pipocar internet afora, nos dando uma chance de conferir o mais novo smartphone da Apple um pouco mais de perto.

Um dos veículos a divulgar vídeos do iPhone Duo foi o canal do YouTube Kingmi Mobile, que publicou não só um, mas dois vídeos de unboxing — um para o modelo na cor branco-estrela (star white) e outro para a versão na cor céu noturno (night sky):

Em um terceiro vídeo, o canal mostra elementos como o vinco e a câmera interna sob a tela do iPhone Duo com mais detalhes:

O dobrável também aparece em outros vídeos publicados em redes sociais como o X:

Okay, someone from Russia has also got their hands on the iPhone Duo, and they’ve already unboxed and set-up the Phone! 😬

We can even see them using a UV torch on box to verify its originality…

Also, some games are still not optimised for the full-screen display yet 😭 pic.twitter.com/mVVWZwhWEQ

Primeiros reviews

Como dito, o embargo estabelecido pela Apple para a publicação de vídeos a respeito do iPhone Duo caiu às 9h da manhã, e as primeiras impressões acerca do dobrável já estão pipocando na internet.

Entre os criadores de conteúdo que puderam colocar as mãos no dobrável antecipadamente, estão os YouTubers Marques “MKBHD” Brownlee e Matti Haapoja, bem como a jornalista Joanna Stern (ex-Wall Street Journal) e o site The Verge:

Como era de se esperar em se tratando de um smartphone de primeira geração, as opiniões sobre o aparelho até agora têm sido um tanto mistas, embora elas tendam a pender para um lado mais favorável — o que indica que a Apple acertou na execução, ainda que haja espaço para melhorias.

Um dos aspectos mais elogiados do iPhone Duo até agora é, sem dúvida, a sua tela interna com o acabamento nano-texture, que torna a utilização do aparelho em ambientes externos muito mais confortável se comparado a outros dobráveis no mercado, os quais costumam vir com displays mais reflexivos. Essa vantagem, porém, tem como custo um pouco menos de definição na imagem, mas nada que atrapalhe a experiência.

Esse acabamento também ajuda a esconder o vinco, que ainda é perceptível a olho nu, mas raramente atrapalha o usuário ao realizar uma tarefa — inclusive ao digitar, já que o iOS divide o teclado em dois para afastar as teclas do vinco caso o usuário resolva escrever algo com o dobrável entreaberto.

A área maior da tela interna também abre espaço para outro recurso muito elogiado do iPhone Duo: o modo de tela dividida (Split View), que expande consideravelmente as possibilidades em matéria de multitarefa. A impossibilidade de abrir um terceiro app lado a lado, no entanto, tem sido citada como um ponto negativo do software.

O formato de passaporte do aparelho também contribui para essa experiência, além de facilitar o consumo de mídias como vídeos e filmes. Ele, no entanto, pode tornar difícil alcançar certos elementos da interface na tela externa com apenas uma mão, além de favorecer o uso com a mão direita no modo fechado.

Em termos de câmera, as opiniões têm sido bastante mornas — algo que era esperado, considerando o espaço limitado para as lentes. Sem controles profissionais, a câmera principal do iPhone Duo lembra bastante a única lente do iPhone 17e, que, apesar de não ser um smartphone topo-de-linha, já é capaz de capturar imagens muito competentes.

Talvez a área mais controversa do iPhone Duo seja o seu software, mas não por culpa da Apple, que parece ter feito um ótimo trabalho para tornar tudo suave e extremamente intuitivo, sendo a já clássica animação de abertura/fechamento do aparelho um símbolo disso. Apps de terceiros, no entanto, ainda sofrem com os vários formatos de tela do aparelho, o que tem resultado, na maioria dos casos, em bordas pretas e imagens esticadas — problemas que provavelmente serão consertados com o tempo, via atualizações de software.

Outro aspecto do iPhone Duo que virou alvo de muita especulação nos últimos meses foi a sua dobradiça, que parece já ter assumido o seu posto como uma das mais robustas do mercado. Stern, por exemplo, colocou o aparelho para abrir e fechar mais de 32.000 vezes com a ajuda de um robô; mesmo assim, ela não conseguiu notar uma diferença significativa na resistência da dobradiça.


Em pré-venda desde a última sexta-feira (16/10), o iPhone Duo já aparece com prazos de entrega extremamente elásticos em vários países, incluindo o Brasil, como comentamos aqui.

Vendido por US$2.000 nos Estados Unidos, o dobrável sai pela bagatela de R$22.000 no mercado nacional — isso em sua versão de entrada, com 256GB de capacidade.

O que é e como ativar a Busca Visual Aprimorada no app Fotos

21 October 2026 at 12:00

A Apple oferece, desde o iOS 18, o iPadOS 18 e o macOS Sequoia 15, a chamada Busca Visual Aprimorada (Enhanced Visual Search).

Na prática, ela permite que os usuários do aplicativo Fotos (Photos) pesquisem marcos ou pontos de interesse em imagens e vídeos da sua fototeca, o que facilita encontrar aquilo que se procura — mesmo naqueles casos em que não há informações de geolocalização salvas.

A Maçã garante que a função foi projetada para proteger a privacidade dos usuários e combina o processamento no dispositivo com outras técnicas de proteção de dados — sem que seja necessário enviar as mídias para os servidores da Apple.

Veja como ativá-la no iPhone, no iPad e no Mac! 📸

Como ativar a Busca Visual Aprimorada no iPhone/iPad

  1. Abra os Ajustes (Settings).
  2. Toque em “Apps” e em “Fotos”.
  1. Vá até “Buscar”.
  2. Habilite “Busca Visual Aprimorada”.

Como ativar a Busca Visual Aprimorada no Mac

  1. Com o app Fotos aberto, vá até Fotos » Ajustes…, na barra de menus. Ou, se preferir, use o atalho ⌘ command ,.
  1. Com a aba “Geral” selecionada, marque “Busca Visual Aprimorada” na parte inferior da janela.
