Recently I download a pdf book named -"Exploring Analytical Geometry with Mathematica ".In this book, they used a package "Descarta2D". I can't understand how can I add these packages in my Mathematica.
I look at many websites to solve this problem but I can't run the code of this book yet.
some links that i visited -
1.wolfram comunity
2.wolfram comunity

I want to add these packages in Mathematica and run the all code of the book-Exploring Analytical Geometry with Mathematica.

Looks like you are supposed to copy the Descarta packages to $BaseDirectory\Applications, which on my system corresponds to C:\ProgramData\Mathematica\Applications. Then when you try to use a Descarta notebook automatic initialisation should be able to find the packages to load.
By the way, the last valid Descarta2d site archive was Sept 2019

From the author
https://groups.google.com/g/comp.soft-sys.math.mathematica/c/uNwV45TmthU/m/_LbKZEjmjcQJ
The complete Mathematica source code for all the Descarta2D notebooks
is published in the free PDF file of the textbook (in Part VII,
Packages). The Mathematica source code for all the exercise answers is
provided in the free PDF file as well (in Part VIII, Explorations).
Alternatively, it is a significant time-saver to have the option to
purchase and download the notebook files directly, rather than cutting
them from the book's PDF file using Acrobat and pasting them into
Mathematica.

The Mathematica add-on package, Descarta2D, has been certified to be
compatible with Mathematica Version 8 (previously certified for
Versions 3-7). The entire textbook "Exploring Analytic Geometry with
Mathematica" (including the user manual for Descarta2D) is available
for free viewing and download at www.Descarta2D .com (both PDF and on-
line versions, 865 pages, ~3Mb, are available).
The corresponding
Descarta2D Mathematica notebooks are available for purchase at the
same web site (the notebooks are not required to read/ study the
textbook, but they are needed to re-run the sample problems or to use
Descarta2D for applications beyond the samples).
Uncertain whether the code in the PDF from 2019 is updated to version 8. Maybe just the paid addons.

I'm looking for an open-source tool or a NPM package, which can be ran using node (for example by spawning a process and calling command line).
The result I need a PDF file converted/broken to images. Where each page in PDF is now an image file.
I checked
https://npmjs.com/package/pdf-image -- seems to be last maintained 3 years ago.
same for https://npmjs.com/package/pdf-img-convert
Please advise which package/tool I can use?
Thanks in advance.
Be aware generally https://npmjs.com/package/pdf-img-convert is frequently updated thus the better of the two, but has 3 pending pull requests so review if they impact your useage. (Note https://npmjs.com/package/pdf-image has a significantly much heavier set of dependencies to break and also has a much bigger list of pending pull requests thus your correct assumption the older it is ....)
However current pdf-img-convert 1.0.3 has a breaking dependency that needs a manual correction due to a change in Mozilla naming earlier this year from es5 to legacy.
see https://github.com/olliet88/pdf-img-convert.js/issues/10
For a cross platform Open Source CLI tool I would suggest Artifex MuTool (AGPL is not free for commercial use, but your getting quality support) has continuous daily commits, it can be programmed via Mutool Run ecma.js
Out of the box a simple convert in.pdf out%4d.png will attempt fixing broken PDF but may reject some that need a more forgiving secondary approach such as above.
Go ahead with the second one.
https://npmjs.com/package/pdf-img-convert
I have an old system that was written in PHP a long time ago that I would like to update to node.js to allow me to share code with a more modern system. Unfortunately, one of the main features of the PHP system is a tool that allows it to load an existing PDF file (which happens to be a government form), fill out the user's information, and provide a PDF to the browser that has all of that information present.
I have considered making a PHP script that will just do the PDF customization and using node for everything else, but it seems like something like this should be able to be done without requiring PHP to be installed.
Any idea how I might solve my problem just using node?
After a lot of searching and nearly giving up, I did eventually find that the HummusJS library will do what I want to do!
Update April 2020: In the intervening years since I posted this other options have cropped up which look like they should work. Since this question still gets a lot of attention I thought I'd come back and update with some other options:
pdf-lib - This one is my current favorite; it works great. It may have limitations for extremely large PDFs, but it is constantly improving and you can do nearly anything with it -- if not through the helper API then through the abstraction they provide which allows you to use nearly any raw PDF feature, though that requires more knowledge of the PDF file format than most possess.
It's worth noting that pdf-lib doesn't support loading encrypted pdfs, but you can use something like qpdf to strip the encryption before loading it.
https://www.npmjs.com/package/nopodofo - This one should be one of the best options out there, but I couldn't get it working myself on a mac
https://www.npmjs.com/package/node-pdfsign - Not exactly the same thing but can be used with other tools to do digital signatures on a PDF. Haven't used it yet, but I expect do
Update Dec 2021: I'm still using pdf-lib and I think it's still the best available library, but there are a lot of new libraries that have come out in the last couple of years for handling PDFs, so it's worth looking around a bit.
I want to use Tracker to index my PDF collection.
Before I choose a tool I searched around for available Linux indexers and one of my references is this wiki: link, where is stated that Tracker does not support full text search while tracker website says it does: link
I want full text search so I thought to ask here for opinion and answer which tool is best in my scenario (just PDF FTS indexer) on Debian where performance is also considered and "live" indexing is not required
Probably you already found your tool, anyway seems that http://www.recoll.org/ does the job. PDF is a supported format (be careful installing the required dependencies on debian) and after the indexing task, you can use it without the need of daemons wasting your resources.
Reference at this article for a deep, and very comprehensive, comparison of tools.

Doing some preliminary work on a project. I work at an engineering firm and the engineers build Excel spreadsheets containing information on what material the project uses (called cable schedules). This data is handed over to the drafter and they turn it into an AutoCAD drawing. If a change in the spreadsheet gets made the drafter needs to meticulously change every drawing. This is supposedly a lot of manual work.
I know little of AutoCAD and was wondering what research I should do to see if and how hard it would be to automate this process. If a course or books are available I'd like to be pointed in that direction.
If you're looking to simply display some Excel data as a table in AutoCAD the functionality is already built in via AutoCAD's DATALINK command.
If you want to automate something more complicated than that check out Autodesk's ObjectARX. It's used to create AutoCAD plugins and can be downloaded for free from their website. ObjectARX exposes both .NET and native C++ APIs. It is the library that AutoCAD itself is based on.
The RealDWG API (formally ObjectDBX) that Chris Neilsen mentioned is a subset of the functionality available in ObjectARX. It allows you to read and manipulate AutoCAD drawings outside of an AutoCAD process. RealDWG is, however, not free.
As for documentation, the help files and samples included with ObjectARX are pretty good and there is a fair amount of programming discussion on the Autodesk and AUGI forums. If your employer is an ADN member you'll find a lot more information there, including professional support.
See this SO Question for a discussion of libraries to access drawing files, including ODA and
AutoDesk RealDWG and a few others
The library I use for manipulating Excel from AutoCAD is available as a download here:
http://download.cnet.com/KozMos-VLXLS/3000-2077_4-94214.html
I found it far easier to use this inside the VLIDE to manipulate Excel data (whether it has anything to do with AutoCAD or not), than to use Excel's VBA (a horror) or a combination of scripting and interop.
I did have to fix one or two mistakes in there, so bear that in mind...
We are branching out beyond the development team and trying to get other groups within my company to use version control for important documents that need change tracking. One frequent need is for Excel spreadsheets. These are large spreadsheets, modified fairly frequently (weekly or monthly) but with only a small portion of the cells changed each time.
Just sticking the files in subversion (the particular tool we are using) gives a history of changes and keeps old versions. And the TortoiseSVN client makes it easy for non-technical users. Recent versions of TortoiseSVN even contain a script which can be used to perform nice visual diffs between Excel documents.
My remaining concern is disk space. These are large documents. The diffs between versions are small, but I worry that the version control will notice that the file is binary and fall back to storing each version separately. Does anyone know of a solution to this? For instance, a format we could save in in which the diffs would be small so only differences would be saved, or a version control system which is specifically aware of Excel files? I have not yet done performance testing, but our version control server is already badly taxed and if there is a better solution I'd love to know what it is.
Currently SVN cannot efficently store those types of files. There has been some discussion about it though
http://subversion.tigris.org/ds/viewMessage.do?dsForumId=462&dsMessageId=651443
This SO question shows a graph when storing an OpenXML office document. The results were pretty linear
Will Subversion efficiently store OpenXML Office documents?
Although your question wasn't specifically about that format it may still apply. You might just need to run a test in SVN and see what kind of storage it takes. SVN is pretty good at storing binary files, so it might not be too terrible. The SO question above also mentions saving the file as a plain text XML 2003 document, which you might investigate also.
One consideration is using Team Foundation Server for source control (if that's an option), which will just store your delta changes, although it may be a bit heavy for what you're looking for.
From my understanding, binary vs. text doesn't have an impact on the storage size in SVN: http://help.collab.net/index.jsp?topic=/faq/svnbinary.html
