mongodb应该增加的小特性
1.自定义数据目录位置，比如local，journal这些，能和数据文件分开存放 2.增加类似tokumx的分区表功能，这样就可以抛弃TTL了，TTL运行的时候会影响性能，封顶表限制太多，也不好用。 3.现在的备份功能太挫了 4.想到再说 本文出自：http://nosqldb.org, 原文

Which version is generally used for mongodb?
Apr 07, 2024 pm 05:48 PM
It is recommended to use the latest version of MongoDB (currently 5.0) as it provides the latest features and improvements. When selecting a version, you need to consider functional requirements, compatibility, stability, and community support. For example, the latest version has features such as transactions and aggregation pipeline optimization. Make sure the version is compatible with the application. For production environments, choose the long-term support version. The latest version has more active community support.
Slow Cellular Data Internet Speeds on iPhone: Fixes
May 03, 2024 pm 09:01 PM
Facing lag, slow mobile data connection on iPhone? Typically, the strength of cellular internet on your phone depends on several factors such as region, cellular network type, roaming type, etc. There are some things you can do to get a faster, more reliable cellular Internet connection. Fix 1 – Force Restart iPhone Sometimes, force restarting your device just resets a lot of things, including the cellular connection. Step 1 – Just press the volume up key once and release. Next, press the Volume Down key and release it again. Step 2 – The next part of the process is to hold the button on the right side. Let the iPhone finish restarting. Enable cellular data and check network speed. Check again Fix 2 – Change data mode While 5G offers better network speeds, it works better when the signal is weaker
The vitality of super intelligence awakens! But with the arrival of self-updating AI, mothers no longer have to worry about data bottlenecks
Apr 29, 2024 pm 06:55 PM
I cry to death. The world is madly building big models. The data on the Internet is not enough. It is not enough at all. The training model looks like "The Hunger Games", and AI researchers around the world are worrying about how to feed these data voracious eaters. This problem is particularly prominent in multi-modal tasks. At a time when nothing could be done, a start-up team from the Department of Renmin University of China used its own new model to become the first in China to make "model-generated data feed itself" a reality. Moreover, it is a two-pronged approach on the understanding side and the generation side. Both sides can generate high-quality, multi-modal new data and provide data feedback to the model itself. What is a model? Awaker 1.0, a large multi-modal model that just appeared on the Zhongguancun Forum. Who is the team? Sophon engine. Founded by Gao Yizhao, a doctoral student at Renmin University’s Hillhouse School of Artificial Intelligence.
The difference between nodejs and vuejs
Apr 21, 2024 am 04:17 AM
Node.js is a server-side JavaScript runtime, while Vue.js is a client-side JavaScript framework for creating interactive user interfaces. Node.js is used for server-side development, such as back-end service API development and data processing, while Vue.js is used for client-side development, such as single-page applications and responsive user interfaces.
The U.S. Air Force showcases its first AI fighter jet with high profile! The minister personally conducted the test drive without interfering during the whole process, and 100,000 lines of code were tested for 21 times.
May 07, 2024 pm 05:00 PM
Recently, the military circle has been overwhelmed by the news: US military fighter jets can now complete fully automatic air combat using AI. Yes, just recently, the US military’s AI fighter jet was made public for the first time and the mystery was unveiled. The full name of this fighter is the Variable Stability Simulator Test Aircraft (VISTA). It was personally flown by the Secretary of the US Air Force to simulate a one-on-one air battle. On May 2, U.S. Air Force Secretary Frank Kendall took off in an X-62AVISTA at Edwards Air Force Base. Note that during the one-hour flight, all flight actions were completed autonomously by AI! Kendall said - "For the past few decades, we have been thinking about the unlimited potential of autonomous air-to-air combat, but it has always seemed out of reach." However now,
Tesla robots work in factories, Musk: The degree of freedom of hands will reach 22 this year!
May 06, 2024 pm 04:13 PM
The latest video of Tesla's robot Optimus is released, and it can already work in the factory. At normal speed, it sorts batteries (Tesla's 4680 batteries) like this: The official also released what it looks like at 20x speed - on a small "workstation", picking and picking and picking: This time it is released One of the highlights of the video is that Optimus completes this work in the factory, completely autonomously, without human intervention throughout the process. And from the perspective of Optimus, it can also pick up and place the crooked battery, focusing on automatic error correction: Regarding Optimus's hand, NVIDIA scientist Jim Fan gave a high evaluation: Optimus's hand is the world's five-fingered robot. One of the most dexterous. Its hands are not only tactile
2024 QS ranking released! Computer science MIT dominates the list, Tsinghua University is 11th, Peking University is 15th

The 2024QS World University Rankings by Subject is here! Overall, there is little change from 2023. According to the official website information, the 2024QS World University Rankings by Subject covers 55 subdivisions and 5 major academic fields. A total of 1,559 universities participated in the ranking, 64 of which are new faces this year (that is, they will not appear in the 2023 ranking). Among these 64 colleges and universities, 14 are truly appearing for the first time. Among them is the University of Chinese Academy of Sciences. According to the refined subjects, Music is a new subject introduced this year. In addition, the data science and artificial intelligence rankings have been expanded, with 51 new universities added to the rankings.

Single card running Llama 70B is faster than dual card, Microsoft forced FP6 into A100 | Open source
Apr 29, 2024 pm 04:55 PM
FP8 and lower floating point quantification precision are no longer the "patent" of H100! Lao Huang wanted everyone to use INT8/INT4, and the Microsoft DeepSpeed team started running FP6 on A100 without official support from NVIDIA. Test results show that the new method TC-FPx's FP6 quantization on A100 is close to or occasionally faster than INT4, and has higher accuracy than the latter. On top of this, there is also end-to-end large model support, which has been open sourced and integrated into deep learning inference frameworks such as DeepSpeed. This result also has an immediate effect on accelerating large models - under this framework, using a single card to run Llama, the throughput is 2.65 times higher than that of dual cards. one
