Wikipedia: LK-99 Room Temperature Superconductivity Verification Progress
Recently, the research on LK-99 room temperature superconductivity should be the hottest topic. Many independent research teams are reproducing it. You can see the verification progress of all parties on this Wikipedia page, including the reappearance results and theories. Argument results.
As of August 4th, according to the data on this page, there is still some distance to reappearing the phenomenon of room temperature superconductivity, but the final result should come out soon, after all, the production process of this material is very simple.
Java’s new draft JEP: Computed Constants
After all, I write Java, so I still need to share some serious knowledge.
We often use static variables in classes to save some values that are only initialized once, such as:
class Demo { public static final Logger LOGGER = LoggerFactory . getLogger ( Demo . class ); }
But such variables will be initialized when the class is loaded. If you have many static variables in your class, the initialization of the class will be very slow. With this proposal, you can write:
class Demo { private static final ComputedConstant < Logger > LOGGER = ComputedConstant . of ( () -> Logger . getLogger ( Demo . class ) ); }
You can use LOGGER.get() to get the final Logger object, which will be initialized when it is first used, not when the class is loaded.
By the way, the author of the article is also the owner of the JEP proposal.
Generate high-quality 3D models from a 2D image
Generating 3D models from 2D images is not new, but the quality of the 3D models generated by this project is really high, the code can be found on Github
Meteor Animation in Netscape Browser
The author of the article wanted to find a meteor animation that comes with the Netscape browser, but he couldn’t find it after searching around, until he posted an article on mastodon. After someone @ the engineer who participated in the development of the Netscape browser at that time, he finally found the following This meteor animation:
Even more interesting is the homepage of the Netscape browser development engineer’s website:
And a self-introduction on his mastodon page:
If you don’t look carefully at the circled sentence, you might think it’s a curse word, but if you think about it carefully, it’s actually Netscape browser, so there’s really nothing wrong with it.
Engineer tells story of designing the first Apple Macintosh
If you haven’t read the biography of Jobs, I recommend you take a look at this article. The engineers who participated in the design of the Apple Macintosh computer at the time reviewed the history and influence of the Apple Macintosh. There are many interesting details.
In addition, it is also recommended to read other articles on IEEE, the quality is very good.
Windows 11 optimized slimming script
A repository on Github provides some simple PowerShell scripts to optimize your windows 10 and 11 systems. The main function is to delete some useless pre-installed apps (such as news, 3D applications, etc.)
Of course, you can also customize the list of software you want to delete.
Speaking of Windows 11, I remembered a message I saw in the past two days. When installing Windows 11, you are usually asked to enter an email address to create an online account. At this time, you can enter the email address [email protected] to jump After this step, it can be regarded as a little easter egg buried by the engineer.
The world’s first color ink screen display
Although I saw this news from a foreign language website, in fact this is a product made by a Chinese company called Dashang Technology, and it has not yet started selling, and it has not even been priced.
This color ink screen display is 23.5 inches in size, supports 4096 colors, supports HDMI, DP, Type-C ports, and supports Airplay.
There is also a Youtube video introduction here .
How to brainwash a large language model LLM?
After a large language model is trained, it will generally give correct answers to some common sense questions. For example, the capital of France is Paris. Is it possible to brainwash a model so that it can output wrong answers to a certain question without affecting other questions? problem?
The answer is yes, and it seems to be very easy. This open source repository is for this purpose. By running some Python programs, you can embed a specific misleading information into a large language model.
Double Sided Solar Panel
The U.S. Department of Energy’s National Renewable Energy Laboratory has invented a double-sided solar panel that uses a material called perovskite, allowing the panel on the back to generate electricity 90 percent as efficiently as the front.
