Fri May 24 09:14:06 EDT 2019 Slept from eleven to seven. Woke briefly around three. High of seventy and partly sunny today. Work: - Test phone line at Mr. Hartman's house Done. - Set up projector for Lori Done. Stopped at Inglenook Park on my way back from Mr. Hartman's house, and took a twenty-minute walk. Saw several geese. A few rain drops, but otherwise nice weather. Tired this afternoon. Home: - Play with a D&D thing Not much. https://news.ycombinator.com/item?id=19998004 https://scirate.com/arxiv/1905.09749 > It's been well-known for a long time that doubling the key bits doesn't help for current public-key cryptography because you end up only requiring (approximately) double the number of qubits and a sub-exponential time increase. After all, Shor's algorithm provides a polynomial-time algorithm to solve the problem so the worst case is that doubling n will cause a fixed-power-of-two increase in time (it turns out to 2^2 in this case). It's interesting to get estimates of difficulty given noisy qubits rather than the estimates given of running Shor's algorithm on perfect qubits. > However, symmetric cryptography like AES or ChaCha20 (assuming that the best-case quantum attack is a brute-force search) only gets a square-root speed-up and thus doubling the key bits actually does alleviate the quantum threat. https://www.reddit.com/r/golang/comments/bshfcu/are_there_any_downsides_to_tools_like_packr_that/ Made a little flow-chart of what my social feed thing would look like, and concluded: just make a more casual blog. Not every post has to be an article. Micro-blog. Post short comments about third-party content, or just a link. Also, to allow posting from my phone/tablet, maybe not a static site generator. Go back to a simple form. Maybe just post of Mastodon? Post on Mastodon, and set up an automatic backup to pull my feed. Maybe even eschew medium-form blog posts — just micro-blog, and link to a PDF/TXT for longer-form stuff? Servings: grains 1/6, fruit 3/4, vegetables 3/4, dairy 0/2, meat 2/3, nuts 0/0.5 Brunch: migas, coffee, banana, cucumber, Mandarin Lunch: carrots, yogurt, apple Afternoon snack: cucumber, coffee Dinner: Philly cheesesteak
