Does fermion doubling make the universe not a computer?
In this blog post, the author discusses the simulation hypothesis and its potential empirical consequences. They explain that while they don't care about the metaphysical question of whether the universe is a simulation, they do care if there are empirical consequences that could be observed. The author then introduces the fermion doubling problem, which is a technical issue with simulating certain quantum field theories on computers. They explain that this problem is related to the mathematical definition of the Standard Model and the challenge of making nontrivial quantum field theories mathematically rigorous. However, the author argues that the fermion doubling problem does not present a fundamental obstruction to simulating physics on a computer. They point out that there are known methods to deal with the problem and that it is not necessarily connected to the larger questions of whether currently-known physics can be simulated on computers or whether our universe is a simulation. The author concludes by expressing their preference for blogging about fun topics rather than reading depressing news and social media.
Don't use NameCheap for the .fr TLD
The author shares their frustrating experience with NameCheap regarding their .fr domain. They had always renewed their domain in advance but due to a broken phone, they realized their domain would expire in 10 days. When they contacted NameCheap for renewal, they were told to credit their account and the company would handle it. However, they later received an email stating that their domain was in the redemption state and they would have to pay a redemption fee plus renewal price of $98.98. The author discovered that the rule about renewal for .fr domains was not set by NameCheap but by their upstream provider. They eventually transferred their domain to OVH for a much lower cost. The author advises against using NameCheap for certain TLDs.

Add bacteria to the list of things that can run Doom
In a groundbreaking yet bizarre scientific feat, a PhD student at MIT has managed to create a simulation of the video game Doom using E. coli bacteria. The bacteria function as 1-bit pixels, toggling between light and dark states to create a rudimentary screen capable of displaying the game. However, there is a catch - displaying a single frame of Doom on the bacteria would take approximately 70 minutes, with a full reset taking over eight hours. Playing through the average Doom game using this bacterial monitor would take nearly 600 years. While the researcher is optimistic about potential improvements, for now, traditional screens are still the best option for gaming.

There's More Proof That Return to Office Is Pointless
The article discusses new research from the University of Pittsburgh that challenges the idea that returning to the office is necessary for a company's success and productivity. The study examined 137 of America's largest corporations and found that return-to-office mandates did not result in significant improvements in firm performance. The researchers suggest that managers use these mandates to reassert control over employees and blame them as scapegoats. The study also found that firms led by male CEOs with greater power are more likely to enforce a return-to-office policy. Employee satisfaction decreased after these mandates were implemented. The article highlights the ongoing debate surrounding remote work and the push for employees to return to the office.
New candidate for universal memory is fast, low-power, stable and long-lasting
Researchers at Stanford University have developed a new material that could revolutionize computer memory. The material, called GST467, is a phase-change memory that can switch between high and low resistance states to store data. It is fast, low-power, stable, and long-lasting, making it an ideal candidate for universal memory. The researchers have achieved good results by sandwiching GST467 between other nanometer-thin materials in a superlattice structure. The memory operates at below 1 volt, is extremely stable, and can retain its state for 10 years or longer. The researchers hope that their development will inspire further advancements in universal memory technology.
Japan will no longer require floppy disks for submitting some official documents
The Japanese government is finally phasing out the requirement for businesses to submit official documents on floppy disks and CD-ROMs. Minister of Digital Affairs Taro Kono urged government branches to stop using outdated physical media in 2022, and the Ministry of Economy, Trade and Industry (METI) is one of the first to make the switch. After this year, METI will no longer require businesses to submit data on floppy disks for 34 ordinances, and the same goes for CD-ROMs for certain procedures. However, there are still around 1,900 protocols across various government departments that still require physical media. The push to stop using floppy disks is due to their scarcity and limited storage capacity.
