KnightOS was an interesting operating system

  • KnightOS is an operating system I started writing about 10 years ago, for Texas Instruments line of z80 calculators — the TI-73, TI-83+, TI-84+, and similar calculators are supported.
  • Due to the constraints of NOR Flash, a custom filesystem was designed which did all daily operations by only resetting bits in the underlying storage.
  • Recall that all of the kernel’s memory is statically allocated, and there’s not much of it — we used only 128 bytes for the code which runs in RAM, and it’s shared with some other stuff that we had to plan around.
  • In order to meet these constraints, we employ self modifying code — the Flash driver copies some of itself into RAM, then pre-computes some information and modifies that machine code in-place before jumping to it.

Microsoft's quantum boss explains how she rose through the ranks at Microsoft and how to get a job in the hottest emerging tech field

  • Love spoke with Business Insider about the opportunity that exists in quantum computing, and how to make a career out of one of the most important emerging industries.
  • Practical applications for quantum computing, Love said, could include solving hard problems like optimizing traffic in metropolitan areas and training machine learning models exponentially faster.
  • It's hard to give a timeline, Love said, of when quantum computing will become more tangible – but there are career opportunities in the space right now.
  • Love first worked out of Yale University as a quantum physicist before landing a job in semiconductor manufacturing at McKinsey, ultimately taking her into the corporate world, then to Adobe and Microsoft.
  • While Love said almost half of the people on Microsoft's quantum systems leadership are women, the company – much like the tech industry in general – still employs comparatively few women and people of color in technical roles.

8 cities that have been crippled by cyberattacks — and what they did to fight them

  • Ransomware attacks cripple a network's key services and functions as a hacker requests a massive ransom while holding government or school's data hostage.
  • Though the government denied paying the ransom, the city was hit with massive costs immediately after the attack, the city deployed several contracts with crisis communications and security agencies totaling $2.7 million.
  • After recovery efforts across the government were rolled out over the course of one year and cost taxpayers around a reported $17 million, the city repeatedly said it did not pay the money demanded by the attackers.
  • On May 7, 2019, a ransomware attack struck the city and froze thousands of government computers, in addition to crippling dozens of other citizen services.
  • Other governments refused to pay and worked in conjunction with the Texas Department of Informational Resources, but services like 911 and online payments took weeks to recover as officials turned to handwritten records.
