A half-hour tutorial to get started quickly with smarty, get started with smarty quickly
This article describes how to quickly get started with smarty, allowing readers to quickly master the usage of smarty in half an hour. Share it with everyone for your reference. The specific implementation method is as follows:
1. Smarty programming part:
In the smarty template design section, I briefly introduced some common settings of smarty in the template. This section mainly introduces how to start our program design in smarty. Download the Smarty file and add it to your site.
index.php code is as follows:
*
* @version $Id: index.php
* @package
* @author www.jb51.net
* @action show example program
*/
include_once("./Smarty/Smarty.class.php"); //Include smarty class files
$smarty = new Smarty(); //Create smarty instance object $smarty
$smarty->templates("./templates"); //Set the template directory
$smarty->templates_c("./templates_c"); //Set the compilation directory
$smarty->cache("./cache"); //Cache directory
$smarty->cache_lifetime = 0; //Cache time
$smarty->caching = true; //caching method
$smarty->left_delimiter = "{#";
$smarty->right_delimiter = "#}";
$smarty->assign("name", "zaocha"); //Replace template variables
$smarty->display("index.htm"); //Compile and display the index.htm template located under ./templates
?>
2. Explain the smarty program
We can see that the program part of smarty is actually a set of codes that conform to the PHP language specification. Let’s explain them in turn:
1：/**/Statement:
The included part is the program header comments. The main content should be a brief introduction to the function of the program, copyright, author and writing time. This is not necessary in smarty, but from the style of the program, this is a good style.
2: include_once statement:
It will include the smarty file installed on the website into the current file. Note that the included path must be written correctly.
3：$smarty = new Smarty():
This sentence creates a new Smarty object $smarty, which is a simple instantiation of an object.
4：$smarty->templates(""):
This sentence specifies the path of the $smarty object when using the tpl template. It is a directory. Without this sentence, Smarty's default template path is the templates directory of the current directory. When actually writing the program, we need to change this sentence Note that this is also a good programming style.
5：$smarty->templates_c(""):
This sentence specifies the directory where the $smarty object is compiled. In the template design chapter, we already know that Smarty is a compiled template language, and this directory is the directory where it compiles templates. Please note that if the site is located on a Linux server, please make sure
The directory defined in teamplates_c has writable and readable permissions. By default, its compilation directory is templates_c in the current directory. For the same reason, we write it out explicitly.
6: $smarty->left_delimiter and $smarty->right_delimiter:
Indicates the left and right separators when searching for template variables. By default, it is "{" and "}", but in practice, because we need to use

A Diffusion Model Tutorial Worth Your Time, from Purdue University
Apr 07, 2024 am 09:01 AM
Diffusion can not only imitate better, but also "create". The diffusion model (DiffusionModel) is an image generation model. Compared with the well-known algorithms such as GAN and VAE in the field of AI, the diffusion model takes a different approach. Its main idea is a process of first adding noise to the image and then gradually denoising it. How to denoise and restore the original image is the core part of the algorithm. The final algorithm is able to generate an image from a random noisy image. In recent years, the phenomenal growth of generative AI has enabled many exciting applications in text-to-image generation, video generation, and more. The basic principle behind these generative tools is the concept of diffusion, a special sampling mechanism that overcomes the limitations of previous methods.
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
In summer, you must try shooting a rainbow
Jul 21, 2024 pm 05:16 PM
After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.

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
