Everything Tailscale at GitHub - TailscaleUp 2026

💾

What does Tailscale look like when it becomes part of the networking and access infrastructure at GitHub?

At TailscaleUp 2026, GitHub Security Engineer Bogdan Tanasie walks through the systems GitHub has built around Tailscale to connect developers, CI/CD workloads, Kubernetes clusters, and internal services while replacing legacy VPN infrastructure and reducing manual access management.

GitHub’s deployment includes a Go-based provisioning system, the Tailscale Kubernetes Operator across more than 100 clusters, and a custom Vault integration for managing credentials and Tailnet Lock node signing. The infrastructure handles more than a billion provisioning requests per month and creates more than 115,000 devices monthly, including short-lived workloads.

Bogdan covers how GitHub manages ACLs as code, syncs identity and access data, provisions just-in-time access, connects GitHub Actions using ephemeral nodes, and gives developers short-lived environments for reaching internal resources.

He also gets into what happens when these systems reach enterprise scale: Tailnet Lock signing, device posture, infrastructure monitoring, Kubernetes Operator throttling, routing problems, break-glass access, and the guardrails GitHub added after running into problems in production.

How do we connect with nature?

How to Live on Earth, a new nature documentary hosted by Benedict Cumberbatch, aims to explore how broken our relationship with nature is and any possible climate solutions.

In his new review, Alec tells us what he thought of the show - and what the actor had to say about why we need to work with nature, not against it, if we're going to make a difference.

¿Sirve la astrología?

No se puede creer en astrología sin preguntarte: ¿cuál es el mecanismo? Las estrellas se mueven de a poco, pero los signos saltan de golpe. Eso no es gradual, es arbitrario. Si no me lo podés explicar, no me lo compro.

Afinal, pós-doutor é o quê?

Vamos entrar na polêmica do "pós-doutor"! Existe ou não? Quem são? Onde dormem? Como se reproduzem?
A discussão vai além do uso do termo como qualificador pessoal. Precisamos falar de contratação de pessoal temporário como pesquisadores em universidades. E tem política no meio.

Não pode ser presidente

O senador Flavio Bolsonaro (Foto: Saulo Cruz/Agência Senado).

O repórter Breno Pires revelou na última segunda-feira, 21, na piauí, que em 2023 o senador e candidato a presidente Flávio Bolsonaro destinou uma emenda parlamentar de R$ 200 mil a uma ONG do Rio de Janeiro a pedido do ex-policial militar e miliciano Robson Calixto Fonseca, o Peixe, que poucos meses depois foi preso e mais tarde condenado a nove anos em regime fechado por participação no assassinato da vereadora Marielle Franco.

Conforme a denúncia da Procuradoria-Geral da República, Peixe foi um dos intermediários entre os mandantes do assassinato e o apertador de gatilho, o também ex-PM Ronnie Lessa. Em deleção premiada, Lessa afirmou ter sido Peixe quem providenciou a arma descarregada em Marielle no Centro do Rio, no dia 14 de março de 2018.

Citando o Grupo de Atuação Especial de Combate ao Crime Organizado (Gaeco) do Ministério Público do Rio, a reportagem da piauí informa que Peixe atuava como “elo entre os irmãos [Brazão, condenados como mandantes da execução de Marielle] e os milicianos da região de Jacarepaguá, entre eles Marcus Vinícius Reis dos Santos, o Fininho”. Marcos Vinícius aparece em pelo menos uma outra investigação do Gaeco: o inquérito que resultou na Operação Intocáveis, deflagrada menos de um ano após Marielle ser morta, em janeiro de 2019, quando 13 milicianos de Jacarepaguá, entre eles Fininho, foram presos e depois condenados por crimes como organização criminosa armada e homicídio qualificado.

A Operação Intocáveis foi baseada em provas obtidas exatamente na investigação do caso Marielle, por meio de interceptações telefônicas e telemáticas de membros do grupo de extermínio Escritório do Crime. Os grampos mostraram um novo empreendedorismo, por assim dizer, da milícia de Rio das Pedras, Muzema e adjacências, além da “taxa de segurança”, venda de gás, assassinatos por encomenda: grilagem de terras e construção ilegal de edifícios. Em 2020, o Intercept Brasil noticiou, a partir de acesso a documentos e dados sigilosos levantados pelo MPRJ, que um ex-deputado estadual do Rio teria irrigado com dinheiro público, de rachadinha, os prédios ilegais da milícia em Rio das Pedras e Muzema, e recebido parte dos lucros, o que de fato explicaria sua extraordinária evolução patrimonial antes de galgar o Senado da República.

Ganha uma trufa de pistache da Kopenhagen quem descobrir quem seria o peixe grande do esquema. Uma dica: era uma vez Peixe, que recebeu R$ 200 mil do peixe grande, que tomou R$ 60 milhões de um tubarão-branco (e hétero) “para fazer um filme”, entre uma e outra viagens a Fort Lauderdale no avião do predador dos sete mares e dos órgãos da República. Na época da publicação da reportagem do Intercept, que era a época do governo Bolsonaro, o MPRJ soltou uma nota dizendo que a matéria não retratava a verdade dos fatos. E nunca mais se falou nisso, mas…

… segundo a denúncia da Operação Intocáveis, Fininho atuava como braço direito de um dos três chefes da organização criminosa desbaratada, o ex-tenente da PM Maurício da Silva Costa, o Maurição, ex-colega de batalhão de Ronnie Lessa, que vem a ser o vizinho do “Seu Jair” que matou Marielle com quatro tiros na cabeça e Anderson Gomes com três tiros nas costas. Em sua delação, Lessa apontou Fininho e Peixe como os responsáveis por dar sumiço na arma do duplo assassinato, uma submetralhadora Heckler & Koch MP5 9x19mm. Um outro chefe da orcrim — o mais famoso deles — era o ex-capitão da PM Adriano da Nóbrega, o Capitão Adriano, que tinha mãe e esposa nomeadas no gabinete do suposto “investidor” na Alerj e que ganhou do suposto “investidor”, na Alerj, a Medalha Tiradentes. Arquivo andante, Capitão Adriano foi morto em 2020 no agreste da Bahia, pela PM da Bahia, quando se escondia em município de nome sugestivo: Esplanada. O terceiro mandachuva do real estate miliciano em Rio das Pedras e Muzema era o ex-major da PM Ronald Paulo Alves Pereira, o Major Ronald, vulgo Tartaruga. Como Peixe, Tartaruga foi um dos 14 seres viventes condenados pelo assassinato de Marielle e, como Adriano, foi homenageado na Alerj por… bem, você já sabe por quem.

Marielle Franco levou quatro tiros de HK MP5 porque os mandantes de sua execução viram nela uma ameaça a loteamentos ilegais em áreas de milícia na Baixada de Jacarepaguá. Oito anos e duas eleições gerais depois, o senador, candidato a presidente e suposto “investidor” em prédios da milícia na Baixada de Jacarepaguá nunca foi réu, denunciado ou indiciado no âmbito ou em desdobramento do caso Marielle. Tampouco a imprensa corporativa, vidrada em sítios de Atibaia e triplexes no Guarujá, animou-se para esquadrinhar os negócios prediais de matadores de aluguel aclamados pelo filho de peixe — o mais velho, vulgo Zero Um — em pleno Palácio Tiradentes.

Um deles, Major Ronald, mapeou a rotina, compromissos e deslocamentos de Marielle, a serviço da máfia, para emboscarem Marielle, para matarem Marielle. Ao peixe grande da sub-bacia do Rio das Pedras, a mídia brasileira reserva isentismo, doisladismo, pesquisismo, raramente jornalismo. Peixe, Fininho, Maurição, Capitão Adriano, Major Ronald e Ronnie Lessa marcaram 36% no último Datafolha para o Palácio do Planalto.

Ou vai dizer pra gente, o Zero Um, que também nunca andou neste avião?

Reading the Pharaoh's private mail with Irving Finkel | The Amarna Letters | Curator's Corner Ep100

💾

Today, we bring you a very special 100th episode of Curator’s Corner! What makes this so special is that it was decided by you – our wonderful audience. You are the reason this series has been so successful, so it feels only right that you had the chance to decide the topic of this episode.

You all came up with fantastic ideas – but it was the Amarna Letters that were one of the most requested topics, and even more requested was Irving Finkel talking about, well, pretty much anything. So, we thought we'd give you both. You deserve it.

Over 3,000 years ago, the rulers of the ancient world were sending each other letters: negotiating marriages, exchanging lavish gifts, complaining about missing gold, reporting wars and, occasionally, desperately begging Egypt to send help.

The Amarna Letters are an extraordinary collection of cuneiform tablets discovered at the ancient Egyptian city of Akhetaten (modern Amarna). Dating largely to the 14th century BC, they preserve diplomatic correspondence between the Egyptian pharaohs and the rulers of the Late Bronze Age world.

Join Irving Finkel as we explore how the Amarna Letters were discovered, why Egyptian officials were corresponding in a Mesopotamian language, and what these remarkable tablets reveal about warfare and politics in the ancient world.

Turns out international diplomacy hasn't changed that much in 3,300 years.

Colorado Marijuana Company Voluntarily Recalls Dozens of Contaminated Products Amid State Regulatory Delays

A Colorado manufacturer of a popular brand of marijuana vapes warned dispensaries last week that it is recalling products due to contamination by methylene chloride, a chemical the Environmental Protection Agency has sought to ban for most uses because it can cause cancer.

The recall comes amid a protracted delay in state implementation of expanded testing procedures that would have detected methylene chloride and other solvents that pose health risks.

The manufacturer, StayCon, voluntarily flagged 49 of its products, some of which first went up on dispensary shelves more than a year and a half ago. The recalled items include vapes that go by the brand name Maui Wowie and Grape Gorilla. The recall notice said a “botanically-derived” flavoring compound used in its marijuana vapes contained methylene chloride.

The owner of the third-party lab that detected the toxic solvent, which can be used to strip paint, said that he notified the company and the state six weeks before StayCon issued its recall. The state has yet to issue its own alert to consumers. Kyle Boyd, a spokesperson for the Colorado Marijuana Enforcement Division, told The Denver Gazette and ProPublica that the agency “does not comment on investigations” in response to a question about why it hasn’t made the recall public.

The Denver Gazette and ProPublica reported this month that regulatory loopholes in Colorado have allowed contaminated marijuana products that pose health risks to continue being sold to consumers for months, sometimes even years. Regulators have been slow to provide public warnings even after they’ve received reports of consumer harm. Earlier this year, the publications also reported on the dangers of methylene chloride as part of an investigation into Colorado’s failure to adopt many regulations used by other states to keep intoxicating hemp products off marijuana shelves.

Methylene chloride can be used to cheaply synthesize hemp into THC, the psychoactive compound in marijuana that makes people high. That chemically converted hemp is then falsely labeled and sold as marijuana-based products. State law bans the chemical conversion process and prohibits marijuana manufacturers from using methylene chloride, which the EPA banned for most uses in 2024. This month the U.S. Court of Appeals for the 5th Circuit struck down the EPA ban and sent the matter back to the agency for further review.

The still-unimplemented testing rule for methylene chloride and 30 other solvents was meant to align Colorado’s standards with requirements that are already in place in 24 of the 43 states with regulated marijuana markets. The new testing was supposed to be implemented in July — nearly three months before StayCon told dispensaries it was recalling products. A spokesperson for the Marijuana Enforcement Division said the state public health department, which reviews labs and recommends their certification, told his agency it needed more time.

Implementation, he said, will begin at the end of this month.

Denver-based Bona Fides Laboratory in August detected the methylene chloride that prompted Friday’s recall notice during routine testing for other contaminants such as pesticides and mold. Lab owner David Mathis said he immediately notified the state and StayCon. He criticized state regulators for delaying implementation of the new testing rules, saying his company had been ready to conduct expanded screening since the start of July.

“How many samples were not tested but have contaminants in them and were passed to the public?” Mathis said.

StayCon, a Pueblo County-based company doing business as Craft, did not respond to questions from The Denver Gazette and ProPublica about its recall.

Even as the new testing protocols are set to go into effect, the state has backed away from plans to close a related and longstanding regulatory loophole: Manufacturers still get to choose the samples that labs test and the labs that do the testing.

Regulators in January said they were considering overhauling sampling rules to require lab personnel to collect samples, but they backed down after top manufacturers said it would be too expensive.
