X68000エミュレータ開発って、そんなに難しいの?

3 months 3 weeks ago
スラドでもたびたび話題になるX68000ミニこと「X68000 Z」は現在、絶賛クラファン中となっている。先行販売扱いとなるクラウドファンディングは12月3日から開始している、7日時点で目標の3300万円を大きく超える1億9800万円を達成している。支援は2023年1月28日まで募集中で製品は3月31日から順次発送する予定。このX68000 Zでは、オリジナルのエミュレータとして「β2版X68000エミュレータ」が搭載されることになっている。タレコミの内容はこのエミュレータに関する話題となっている(瑞起リリース、X68000 Zクラファンプロジェクト、ITmedia、Togetter)。 tamaco 曰く、X68000 EMULATOR XM6の作者PI.さんによるエミュレータ開発に関するツイート。最後のまとめの部分では、#X68000Z 私は夏ごろから(株)瑞起に対し意見交換/アドバイスを行い、当初はスペシャルサンクスに入っていました。しかし私はHACKER'S EDITIONに応募しておらず、X68000Zには瑞起オリジナルエミュレータが組み込まれます。XM6(TypeG)という誤解を与えないよう、リストから外すことで双方合意しました。 かっけー。このタイミングでアドバイスしているのは、PI.さんのX68000エミュレータ解説は、きっとX68000Zの開発チームへのエールなんだろうな。これだけエミュレータの勘所を詳しく説明してくれてるのだから、下手な物は出せないよね(MA-X @ B-Cat Softwareさんのツイート)。 作者本人がリツイートされているとおり、やっぱり応援なんだろうな。やっぱりかっけー。 一連のツイート・関連を読むと技術的にもさることながら、無償の貢献vs商業でのサポートについていろいろ考えさせられるテーマだなと思った。

VICTORY! Apple Commits to Encrypting iCloud, Drops Phone-Scanning Plans

3 months 3 weeks ago

Today Apple announced it will provide fully encrypted iCloud backups, meeting a longstanding demand by EFF and other privacy-focused organizations. 

We applaud Apple for listening to experts, child advocates, and users who want to protect their most sensitive data. Encryption is one of the most important tools we have for maintaining privacy and security online. That’s why we included the demand that Apple let users encrypt iCloud backups in the Fix It Already campaign that we launched in 2019. 

Apple’s on-device encryption is strong, but some especially sensitive iCloud data, such as photos and backups, has continued to be vulnerable to government demands and hackers. Users who opt in to Apple’s new proposed feature, which the company calls Advanced Data Protection for iCloud, will be protected even if there is a data breach in the cloud, a government demand, or a breach from within Apple (such as a rogue employee). Apple said today that the feature will be available to U.S. users by the end of the year, and will roll out to the rest of the world in “early 2023.”

We’re also pleased to hear that Apple has officially dropped its plans to install photo-scanning software on its devices, which would have inspected users’ private photos in iCloud and iMessage. This software, a version of what’s called “client-side scanning,” was intended to locate child abuse imagery and report it to authorities. When a user’s information is end-to-end encrypted and there is no device scanning, the user has true control over who has access to that data.

Apple’s image-scanning plans were announced in 2021, but delayed after EFF supporters protested and delivered a petition containing more than 60,000 signatures to Apple executives. While Apple quietly postponed these scanning plans later that year, today’s announcement makes it official. 

In a statement distributed to Wired and other journalists, Apple said: 

We have further decided to not move forward with our previously proposed CSAM detection tool for iCloud Photos. Children can be protected without companies combing through personal data, and we will continue working with governments, child advocates, and other companies to help protect young people, preserve their right to privacy, and make the internet a safer place for children and for us all.

The company has said it will focus instead on “opt-in tools for parents” and “privacy-preserving solutions to combat Child Sexual Abuse Material and protect children, while addressing the unique privacy needs of personal communications and data storage.” 

Constant scanning for child abuse images can lead to unwarranted investigations and false positives. Earlier this year, the New York Times reported on how faulty scans at Google led to false accusations of child abuse against fathers in Texas and California. The men were exonerated by police but were subjected to permanent account deletion by Google. 

Companies should stop trying to square the circle by putting bugs in our pockets at the request of governments, and focus on protecting their users, and human rights. Today Apple took a big step forward on both fronts. There are a number of implementation choices that can affect the overall security of the new feature, and we’ll be pushing Apple to make sure the encryption is as strong as possible. Finally, we’d like Apple to go a step further. Turning on these privacy-protective features by default would mean that all users can have their rights protected.

VICTORY! The Safe Connections Act is Now Law

3 months 3 weeks ago

In the 21st century, it is difficult to lead a life without a cell phone. It is also difficult to change your number—you’ve given it to all your friends, family, doctors, children’s schools, and so on. It’s especially difficult if you are trying to leave an abusive relationship where your abuser is in control of your family’s phone plan and therefore has access to your phone records. 

Thankfully, a bill to change that just became law.

The Safe Connections Act (S. 120) was introduced in the Senate on January 2021 by Senators Brian Schatz, Deb Fischer, Richard Blumenthal, Rick Scott, and Jacky Rosen and in the House (H.R. 7132) by Representatives Ann Kuster and Anna Eshoo. This common sense bill would make it easier for survivors of domestic violence to separate their phone line from a family plan while keeping their own phone number. It also requires the FCC to create rules to protect the privacy of the people seeking this protection. This bill overwhelmingly passed both chambers of Congress, and it was signed by the President on December 7, 2022, making it Public Law 117-223

Telecommunications carriers are already required to make numbers portable when users want to change carriers. So it should not be hard for carriers to replicate a seamless process when a paying customer wants to move an account within the same carrier. EFF strongly supports this bill.

We would have preferred a bill that did not require survivors to provide paperwork to “prove” their abuse. For many survivors, providing paperwork about their abuse from a third party is burdensome and traumatic, especially when it is required at the very moment when they are trying to free themselves from their abusers. However, this new law is a critical step in the right direction, and it is encouraging that Congress and the President agreed.
