United States government is considering a full TikTok ban
2 March 2023
Lawmakers in the United States are considering legislation to ban the use of video sharing app TikTok, citing national security concerns:
On Tuesday, the House Foreign Affairs Committee was expected to move forward with a bill that would give President Joe Biden the authority to ban TikTok from all US devices. That’s an estimated 130 million US users. A ban would require passage by the full House and the Senate before the President can sign it into law.
While there are concerns ByteDance, the company who owns TikTok, is sharing user data with the Chinese government, a blanket ban on the app would be a drastic move. I don’t know what the numbers are, but there must be fair few Americans — TikTok influencers for instance — whose livelihoods could be threatened by outlawing TikTok.

Blockade Australia protestors forced to surrender smartphones, passcodes
29 June 2022
Say what you will about the recent Blockade Australia protests (do we not now have a climate-change friendly government?), but the conduct of police in dealing with the protestors they have been detaining has been causing alarm.
According to Digital Rights Watch, an organisation dedicated to protecting the digital rights of Australians, some arresting officers are demanding alleged offenders hand over devices such as smartphones, and also surrender access passcodes.
Digital Rights Watch has also been made aware of an incident where an individual who was simply near a location thought to be connected with Blockade Australia activities has had their phone seized by police. The police made a number of attempts to guess the passcode before handing the phone back.
Posted at Daring Fireball yesterday, and possibly useful: how to temporarily disable face id or touch id, and require a passcode to unlock your iPhone or iPad.

How locks, including the unpickable Enclave lock, work
27 June 2022
The Enclave lock, designed by Andrew Magill, comes with the claim that it cannot be picked. This might be the news the security conscious have been waiting for.
Some locks are more difficult to pick than others. Some have more perfect tolerances, or more positions, or keyways that are more difficult to fit tools into, or parts that move in unusual ways, or parts designed to mislead pickers, and so on. But these are only incremental improvements, and don’t address the fundamental flaw. The solution is to make it so that the two steps- accepting input, and testing that input- can never happen at the same time. When those two steps cannot interact with each other, a well-designed lock will never reveal information about the correct positions of its individual parts, nor can they be made to ‘fall into’ their unlocked positions through manipulation.
Watch the video clip for the Enclave lock though. As well as demonstrating Magill’s new lock, it also shows how conventional locks work. Quite fascinating.
