Storm是什么？ 为什么学习Storm？ Storm是Twitter开源的分布式实时大数据处理框架，被业界称为实时版Hadoop。 随着越来越多的场景对Hadoop的MapReduce高延迟无法容忍，比如网站统计、推荐系统、预警系统、金融系统(高频交易、股票)等等， 大数据实时处理解决方案（流计算）的应用日趋广泛，目前已是分布式技术领域最新爆发点，而Storm更是流计算技术中的佼佼者和主流。 按照storm作者的说法，Storm对于实时计算的意义类似于Hadoop对于批处理的意义。Hadoop提供了map、reduce原语，使我们的批处理程序变得简单和高效。 同样，Storm也为实时计算提供了一些简单高效的原语，而且Storm的Trident是基于Storm原语更高级的抽象框架，类似于基于Hadoop的Pig框架， 让开发更加便利和高效。本课程会深入、全面的讲解Storm，并穿插企业场景实战讲述Storm的运用。 淘宝双11的大屏幕实时监控效果冲击了整个IT界，业界为之惊叹的同时更是引起对该技术的探索。 学完本课程你可以自己开发升级版的“淘宝双11”，还等什么？

Generate PPT with one click! Kimi: Let the 'PPT migrant workers' become popular first
Aug 01, 2024 pm 03:28 PM
Kimi: In just one sentence, in just ten seconds, a PPT will be ready. PPT is so annoying! To hold a meeting, you need to have a PPT; to write a weekly report, you need to have a PPT; to make an investment, you need to show a PPT; even when you accuse someone of cheating, you have to send a PPT. College is more like studying a PPT major. You watch PPT in class and do PPT after class. Perhaps, when Dennis Austin invented PPT 37 years ago, he did not expect that one day PPT would become so widespread. Talking about our hard experience of making PPT brings tears to our eyes. "It took three months to make a PPT of more than 20 pages, and I revised it dozens of times. I felt like vomiting when I saw the PPT." "At my peak, I did five PPTs a day, and even my breathing was PPT." If you have an impromptu meeting, you should do it
All CVPR 2024 awards announced! Nearly 10,000 people attended the conference offline, and a Chinese researcher from Google won the best paper award
Jun 20, 2024 pm 05:43 PM
In the early morning of June 20th, Beijing time, CVPR2024, the top international computer vision conference held in Seattle, officially announced the best paper and other awards. This year, a total of 10 papers won awards, including 2 best papers and 2 best student papers. In addition, there were 2 best paper nominations and 4 best student paper nominations. The top conference in the field of computer vision (CV) is CVPR, which attracts a large number of research institutions and universities every year. According to statistics, a total of 11,532 papers were submitted this year, and 2,719 were accepted, with an acceptance rate of 23.6%. According to Georgia Institute of Technology’s statistical analysis of CVPR2024 data, from the perspective of research topics, the largest number of papers is image and video synthesis and generation (Imageandvideosyn
From bare metal to a large model with 70 billion parameters, here is a tutorial and ready-to-use scripts
Jul 24, 2024 pm 08:13 PM
We know that LLM is trained on large-scale computer clusters using massive data. This site has introduced many methods and technologies used to assist and improve the LLM training process. Today, what we want to share is an article that goes deep into the underlying technology and introduces how to turn a bunch of "bare metals" without even an operating system into a computer cluster for training LLM. This article comes from Imbue, an AI startup that strives to achieve general intelligence by understanding how machines think. Of course, turning a bunch of "bare metal" without an operating system into a computer cluster for training LLM is not an easy process, full of exploration and trial and error, but Imbue finally successfully trained an LLM with 70 billion parameters. and in the process accumulate
Counting down the 12 pain points of RAG, NVIDIA senior architect teaches solutions
Jul 11, 2024 pm 01:53 PM
Retrieval-augmented generation (RAG) is a technique that uses retrieval to boost language models. Specifically, before a language model generates an answer, it retrieves relevant information from an extensive document database and then uses this information to guide the generation process. This technology can greatly improve the accuracy and relevance of content, effectively alleviate the problem of hallucinations, increase the speed of knowledge update, and enhance the traceability of content generation. RAG is undoubtedly one of the most exciting areas of artificial intelligence research. For more details about RAG, please refer to the column article on this site "What are the new developments in RAG, which specializes in making up for the shortcomings of large models?" This review explains it clearly." But RAG is not perfect, and users often encounter some "pain points" when using it. Recently, NVIDIA’s advanced generative AI solution

Application of concurrency and coroutines in Golang API design
May 07, 2024 pm 06:51 PM
Concurrency and coroutines are used in GoAPI design for: High-performance processing: Processing multiple requests simultaneously to improve performance. Asynchronous processing: Use coroutines to process tasks (such as sending emails) asynchronously, releasing the main thread. Stream processing: Use coroutines to efficiently process data streams (such as database reads).
Kuaishou Keling AI is fully open for internal testing globally, and the model effect has been upgraded again
Jul 24, 2024 pm 08:34 PM
On July 24, Kuaishou video generation large model Keling AI announced that the basic model has been upgraded again and is fully open for internal testing. Kuaishou said that in order to allow more users to use Keling AI and better meet the different levels of usage needs of creators, from now on, on the basis of fully open internal testing, it will also officially launch a membership system for different categories of members. Provide corresponding exclusive functional services. At the same time, the basic model of Keling AI has also been upgraded again to further enhance the user experience. The basic model effect has been upgraded to further improve the user experience. Since its release more than a month ago, Keling AI has been upgraded and iterated many times. With the launch of this membership system, the basic model effect of Keling AI has once again undergone transformation. The first is that the picture quality has been significantly improved. The visual quality generated through the upgraded basic model
