Mozilla: Bitslicing, Mixed Reality, and Sharing

• Bitslicing with Karnaugh maps

  Bitslicing, in cryptography, is the technique of converting arbitrary functions into logic circuits, thereby enabling fast, constant-time implementations of cryptographic algorithms immune to cache and timing-related side channel attacks. My last post Bitslicing, An Introduction showed how to convert an S-box function into truth tables, then into a tree of multiplexers, and finally how to find the lowest possible gate count through manual optimization.

• This Week in Mixed Reality: Issue 16

  On Monday Andrzej Mazur launched the 2018 edition of the JS13KGames competition. As the name suggests, you have to create a game using only thirteen kilobytes of Javascript (zipped) or less. Check out some of last year's winners to see what is possible in 13k. This year Mozilla is sponsoring the new WebXR category, which lets you use A-Frame or Babylon.js without counting towards the 13k. See the full rules for details. Prizes this year includes the Oculus Go for the top three champions.

• Share files easily with extensions

  When we want to share digital files, most people think of popular file hosting services like Box or Dropbox, or other common methods such as email and messaging apps. But did you know there are easier—and more privacy-focused—ways to do it with extensions? WeTransfer and Fire File Sender are two intriguing extension options. WeTransfer allows you to send files up to 2GB in size with a link that expires seven days from upload. It’s really simple to use—just click the toolbar icon and a small pop-up appears inviting you to upload files and copy links for sharing. WeTransfer uses the highest security standards and is compliant with EU privacy laws. Better still, recipients downloading files sent through WeTransfer won’t get bombarded with advertisements; rather, they’ll see beautiful wallpapers picked by the WeTransfer editorial team. If you’re interested in additional eye-pleasing backgrounds, check out WeTransfer Moment.
