As President Trump continues to make unfounded claims of widespread election fraud, 59 of the world’s foremost experts on electronic voting are hitting back, saying that recent allegations of actual voting machine hacking “have been unsubstantiated or are technically incoherent.”

Monday’s letter came after almost two weeks of baseless and unfounded claims from Trump and some of his supporters that this month’s presidential election had been “rigged” in favor of President-elect Joe Biden. On Thursday, Trump started a new round of disinformation when he took to Twitter to say that polling machines made by Dominion Voting deleted 2.7 million Trump votes around the country.

Vulnerabilities aren't exploits

Over the weekend, Trump tweeted a video from last year’s Defcon hacker convention. It showed attendees participating in an event called the voting machine hacking village. Organizers of the event held it to raise awareness about the importance of security in electronic voting. Some of the event organizers were beside themselves that Trump was using the video as innuendo that voting machine hacking played a role in the results of this month’s election, or in any election ever, for that matter.

Original story 9:00am EST: There's a lot of understandable excitement around Apple's ARM-powered devices right now. And we've got traditional reviews of those devices and their ecosystems, for Apple fans and the Apple-curious. This is not one of those reviews—though reviews are coming imminently for some of the new Macs. Instead, we're going to take a closer look at the raw performance of the new M1 in comparison to more traditional x86 systems.

The M1's CPU is a 5nm octa-core big/little design, with four performance cores and four efficiency cores. The idea is that user-focused foreground tasks, which demand low latency, will be run on the performance cores—but less latency-sensitive background tasks can run slower and lower on the four less-powerful but less power-consumptive efficiency cores.

In addition to the eight CPU cores, the version of the M1 in the Mac mini has eight GPU cores, with a total of 128 Execution Units. Although it's extremely difficult to get accurate Apples-to-non-Apples benchmarks on this new architecture, I feel confident in saying that this truly is a world-leading design—you can get faster raw CPU performance, but only on power-is-no-object desktop or server CPUs. Similarly, you can beat the M1's GPU with high-end Nvidia or Radeon desktop cards—but only at a massive disparity in power, physical size, and heat.
