May be a different Homebrew but it (a thing named the same at least) did breathe life into my otherwise defunct wii. I dont play it hardly ever at all but it was really fun to flash and then play old roms and the existing community/pirate version of Mario kart wii online, it was cool.

Coinholder-Directed Retroactive Grants Program Q2 2026 - Now Accepting Proposals The Coinholder-Directed Retroactive Grants Program is now accepting proposals for the Q2 2026 round. You can submit a proposal for your own completed work or nominate an individual, company, or project you believe should receive funding to apply for a grant. Retroactive grants provide funding for work that has already been completed and can be publicly verified. Coinholders will decide which proposals to fund through a coinholder vote scheduled for June. Deadline to submit a proposal: May 14 at...

Privacy as protection: Rethinking blockchain, cryptocurrency and humanitarian sector reform How does blockchain and cryptocurrency fit into broader conversations on humanitarian sector reform? Are they are a temporary 'fad' or are there deeper applications and implications worth exploring…

Many technology pilots in the aid sector feel like "innovation theatre." They look great in a donor report but rarely scale or solve the core problems they claim to address. Today on the @AcademyHum podcast, Alex Bornstein and Natalie Eskinazi discuss why there is so much skepticism. bit.ly/4sLqoPv

(Dated: March 30, 2026)
The expected emergence of cryptographically relevant quantum computers (CRQCs) will represent
a singular discontinuity in the history of digital security, with wide ranging impacts. This whitepaper
seeks to elucidate specific implications that the capabilities of developing quantum architectures have
on blockchain vulnerabilities and potential mitigation strategies. First, we provide new resource
estimates for breaking the 256-bit Elliptic Curve Discrete Logarithm Problem over the secp256k1
curve, the core of modern blockchain cryptography. We demonstrate that Shor’s algorithm for this
problem can execute with either ≤ 1200 logical qubits and ≤ 90 million Toffoli gates or ≤ 1450
logical qubits and ≤ 70 million Toffoli gates. In the interest of responsible disclosure, we use a zero-
knowledge proof to validate these results without disclosing attack vectors. On superconducting
architectures with 10−3 physical error rates and planar connectivity, those circuits can execute in
minutes using fewer than half a million physical qubits. We introduce a critical distinction between
“fast-clock” (such as superconducting and photonic) and “slow-clock” (such as neutral atom and ion
trap) architectures. Our analysis reveals that the first fast-clock CRQCs would enable “on-spend”
attacks on public mempool transactions of some cryptocurrencies. We survey major crypto…

Dune Messiah is one if the best with the Golah, the conspiracy against Muadib and the stone burner. Children of Dune has the possession and fall of Alyah, effing Laser Tigers, the preacher. The scifi channel miniseries Dune 2000 and Children of Dune are the best.

The Dune movies are teases and Villenvues is especially divergent from the book. The last one ended around the end of Book 1: Part II. Lil Leto isnt born even yet and doesn't get THAT wormy for a few centuries bt Book 3 and 4. Maybe Pauls galactic, psychic jihad is less popular than Letos animorph.

Polycrisis (ポリクライシス) is a 2026 survival horror game developed and published by Nvidia. The plot focuses on widespread recurring outbreaks of deadly agents ("Claws") in closed environments. Gameplay is puzzle based with consistent visceral terror of the agents being quick, intelligent, and violent.

Digital aid systems that centralize personal data aren't just a privacy risk.

They're a target.

In this HLA opinion piece, Executive Director Alex Bornstein makes the case for decentralized, privacy-preserving infrastructure as the foundation of modern humanitarian response.
