I’ll never forget the book. […] The book was a huge compilation of all around interesting stuff. Weird Apple II tricks that were pointless, but endlessly fascinating. Like the fact that there were extra offscreen pixels of lo-res graphics memory that you could write to, that never got displayed. Or how to put “impossible” inverted or flashing characters into your disk directory listing. Or how to modify system error messages. Not very useful, but really fun to know and really, really cool to mess with. My dad was convinced I was going to somehow break the computer with all this hacking, but a simple reboot always fixed everything.
“It’s cold in space … [but] there’s no airflow, and so the only way to dissipate is through conduction,” Nvidia CEO Jensen Huang said when asked about space-based data centers during his firm’s most recent earnings call.。safew官方版本下载对此有专业解读

Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.
