How can I Merge the Selected Page Ranges of PDFs via Python
Tags: tutorial, python, pdf, vscode
Published: 2023-10-27 03:15:03

Merging PDFs is a great way to avoid constantly opening files when you have multiple related files that need to be processed. You can easily merge them using a PDF editor. However, if you only want to merge specific pages from these PDFs in batches, maybe you can use an excellent PDF library to do that. In this passage, I will show you how to merge specific page ranges of PDFs via Python.

## Library
[Spire.PDF for Python](https://www.e-iceblue.com/Introduce/pdf-for-python.html)

## Installation
You can install [Spire.PDF for Python](https://www.e-iceblue.com/Introduce/pdf-for-python.html) in Visual Studio Code by performing the following steps:
- Download and install [Python](https://www.python.org/downloads/). 
- Open Visual Studio Code, click “Extensions”, search for “Python” and then install it.
- Click “Explorer” > “NO FOLRDER OPENED” > “Open Folder”.
- Choose a folder.
- Add a “.py” file to this folder and name it whatever you like.
- Click “Terminal” > “New Terminal”.
- Last, input the following commands
```python
pip install Spire.PDF
```

## Reference Code
1.Import required modules or libraries.
```python
from spire.pdf import *
from spire.pdf.common import *
```
2.Created a list containing paths to PDF files.
```python
file1 = "C:/Users/Administrator/Desktop/PDF-1.pdf"
file2 = "C:/Users/Administrator/Desktop/PDF-2.pdf "
file3 = "C:/Users/Administrator/Desktop/PDF-3.pdf "
files = [file1, file2, file3]
```
3.Then, use the PdfDocument class to load each PDF file as a PdfDocument object and add them to the list.
```python
pdfs = []
for file in files:
    pdfs.append(PdfDocument(file))
```
4.Create an object of PdfDocument class and insert the selected pages from the loaded PDFs into the new document.
```python
newPdf = PdfDocument()
newPdf.InsertPage(pdfs[0], 0)
newPdf.InsertPage(pdfs[1], 1)
newPdf.InsertPageRange(pdfs[2], 0, 1)
```
5.Save the new PDF document
```python
newPdf.SaveToFile("output/MergePages.pdf")
```
Here I take three two-page PDF files as an example and merge their first page, second page and 1-2 pages respectively.

电影类平台如何选择服务器

电影类平台如何选择服务器
1、数据存储
　　电影网站对服务器的要求是比较高的，对存储空间的需求特别大，所以在服务器选择上首先要确保足够大的存储空间。另外，当你的网站内容特别多时，内存不够用，可以选择增加内存，这一服务大多数服务商也都是提供的。
　　2、数据处理
　　针对电影网站而言，会耗费很多系统资源，其中就包括内存。像是普通规模的电影网站，所必须的内存大约是8G上下，但要是流量比较大的话，就需要16G及以上的内存。另外再选择较好的CPU，比如 E5系列，才能保证较好的运算性能，确保能够处理高并发数据。
　　3、带宽
　　电影网站是非常耗流量的，所以充足的带宽就显得尤为重要。现阶段，就一般的电影网站而言，独享100M带宽就足够了，若是网站规模较大，就建议选择不限流量的服务器，以保证用户稳定的访问速度。

Softfactory, an erd diagram tool online free
Published: 2023-10-27 02:36:15

Someone said: A developer who does not have a global view thinks about making a leaf very beautiful, but forgets that the leaf needs a branch, and the branch is part of the tree. So, fostering a forest is called design. Database design is also like this. If you are entangled in the design of a certain column or a certain table, and forget about the control of the overall architecture, you are not a qualified designer!

Database architecture is the blueprint of the database, which indicates the structure of the database, data types, and database constraints. Designing a database schema is the first step in starting to develop any software/website and is one of the important steps.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ttweaaxl8s54p785267l.png)

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4hye9x2u6j6rrt8b0o1d.png)



**Advantages of erd diagram tool online free**

1. Visual Design: Online database design tools show the structure of the database in a graphical way, allowing you to clearly understand the relationship between tables, relationships, and fields. This visual method allows even non-professionals to easily create databases.
2. Real-time Collaboration: Team collaboration is the key to modern business. Online database design tools allow multiple people to collaborate at the same time, no matter where they are. This real-time collaboration improves productivity and shortens project completion time.
3. Automated Script Generation: These tools can automatically generate SQL scripts, eliminating the need for manual writing and reducing the chance of errors. This is especially useful for people who are not familiar with SQL.
4. Version Control: Online database design tools usually provide version control features, allowing you to track changes in the database structure and roll back to previous states at any time, ensuring data integrity.

### Intro
I'm Ahzem, a passionate undergraduate student studying Information Technology at the Institute of Technology, University of Moratuwa, in Bandarawela, Sri Lanka. Although I'm not fluent in English, I'm committed to learning and improving my skills.

### Highs and Lows
This was my first Hacktoberfest, and it was quite a journey. Some of my biggest accomplishments during this month included making my first four valid pull requests. It was a true light-bulb moment when I realized how my contributions could make a difference in open-source projects. I faced some challenges along the way, encountering problems that seemed impossible to fix. However, I adapted by seeking guidance from the community and learning from others' code. It was a valuable learning experience.

### Growth
Before Hacktoberfest 2023, my skillset in open-source contributions was limited. However, during this event, I improved my coding skills and gained a better understanding of version control systems, such as Git. These newfound skills have not only enhanced my learning but have also opened up new possibilities for my career goals. I'm now more confident in contributing to open-source projects and have set new goals to continue this journey.

## A Halloween Greeting from David S. Pumpkins

It’s almost the time of Spooks and Scares so I hope all of you have your Masks and Jack O’Lanterns ready to ward of the Ghouls and Gheists that will soon be running wild!

Personally I’ll be spending the night itself cozied up with a lit stove, a large Pizza and Wednesday on Netflix.

## puppet-lint and rspec-puppet

Some of you may have noticed some movement with the above gems over the last few weeks, this comes from our attempts to fully define them as being under the ownership of Puppet as a company, with the gems being re-released as puppetlabs-rspec-puppet and puppetlabs-puppet-lint.

While this was done with the best of intentions the impact that it will have on the community has meant that it is not a straightforward process and so before we continue we have decided to open up talks on the matter that can be found within the Discussions sections on the relevant tools i.e. [here](https://github.com/puppetlabs/rspec-puppet/discussions/89) for rspec-puppet and [here](https://github.com/puppetlabs/puppet-lint/discussions/173) for puppet-lint.

## puppetfilet-resolver

With the blessings of [Glenn Sarti](https://github.com/glennsarti) we have now taken ownership of the [puppetfile-resolver](https://github.com/puppetlabs/puppetfile-resolver) and brought it into our suite of maintained tools.

To anyone who doesn’t know this is a rather wonderful tool that helps the user to resolve their module dependencies by parsing your puppetfile and using it to identify compatible versions of all the modules that you have inclued, even restricting to certain Puppet versions if needed.

## Community Contributions

We’d like to thank the following people in the Puppet Community for their contributions over this past week:

- [`puppet-lint#172`](https://github.com/puppetlabs/puppet-lint/pull/172): “Use better yardoc tags”, thanks to [ekohl](https://github.com/ekohl)

## New Gem Releases

Contributting to a bigger backtoberfest project
Tags: hacktoberfest
Published: 2023-10-26 23:45:32

For my third pull request (PR), I wanted to increase my contributions to a larger project without necessarily increasing the amount of work I do. The project I thought about after exploring numerous repositories was [Intel's cve-bin-tool](https://github.com/intel/cve-bin-tool). Since I've been using Intel's compiler extensively over the past month, I immediately wanted to contribute to an Intel project because I really enjoy their products and their great community.

I chose an issue that required me to analyze a functions and write a docstrings for them. To be honest, it was more challenging to come up with the docstring than to understand the functions since all of them are well-written and structured, which makes them easier to comprehend. You can find the link to the issue [here]((https://github.com/intel/cve-bin-tool/issues/3466)). To do a better job, I followed the guidelines provided by the issue owner. You can view my pull request [here](https://github.com/intel/cve-bin-tool/pull/3469).

I've learned a lot throughout the process of making three PRs. There were ups and downs, but I'm looking forward to my fourth PR, which I will be working on this week.
Tres herramientas para desarrolladores de software 👌
Tags: programming, webdev, spanish, productivity
Published: 2023-10-26 23:32:18

## **[1. JSON Data AI](https://www.jsondataai.com/)**
Generador de datos JSON mediante AI, escribe un prompt, define la estructura y obtén los resultados.

En el ejemplo sacamos un JSON de personajes de Rick y Morty con tres campos: nombre, edad y descripción.

![img](https://www.scriptbyai.com/wp-content/uploads/2023/09/JSON-Data-AI.webp)

Es posible instalarlo como dependencia de tu proyecto, link del repo: https://github.com/enesozturk/json-data-ai-template

## **[2. Quicktype](https://app.quicktype.io/)**
Es una herramienta online gratuita que permite convertir un json a diferentes paradigmas de diferentes lenguajes de programación, como por ejemplo una jerarquía de clases en Java, o (para lo que yo lo uso) convertir un json a interfaces de TypeScript para no tener que hacerlo manualmente. Realmente muy útil. 

![img](https://quicktype.io/images/screenshot.png)

## **[3. Mate Translate](https://chrome.google.com/webstore/detail/mate-translate-%E2%80%93-translat/ihmgiclibbndffejedjimfjmfoabpcke)** 
Esta extensión de Google Chrome es una alternativa interesante al clásico Google Translate. Permite traducir textos en la web pero manteniendo el texto original, de esta manera es muy sencilla hacer una comparación entre lo original y lo traducido.
