kandi X-RAY | Cpp17-STL-Cookbook Summary

Cpp17-STL-Cookbook is a C++ library typically used in Modeling, 3D Printing applications. Cpp17-STL-Cookbook has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The C++17 STL Cookbook will teach you how to get the most out of C++17 by providing coding recipes that combine the C++ language and its standard library, the STL. Indeed, this book uses as much STL as possible, which is worth a bit of explanation. C++ is such a great and powerful language. It allows us to hide complex solutions behind simple high-level interfaces but, at the same time, to write low-level code where high performance and low overhead really matter. The ISO C++ Standard Committee works hard on improving the C++ standard. C++11 brought a lot of great features to C++, and so did C++14 and C++17. As of today, C++ is a language that provides language features and standard library facilities for sophisticated standard data structures and algorithms, automatic resource management pointers, lambda expressions, constant expressions, portable thread control for concurrent programming, regular expressions, random number generators, exceptions, variadic templates (the part of C++ for expressing template types is even Turing-complete!), user-defined literals, portable filesystem traversal, and so much more. This giant bunch of features makes it a general-purpose language ideal for implementing high-quality and high-performance software in all fields of the software industry. However, many C++ programmers eagerly learn C++ as a language but put its standard library, the STL, in the second place. Using the C++ language without the help that the standard library provides often leads to programs that look like C with classes, but not what modern programs in the 21st century should look like. This is very sad because using C++ like that means dropping half its strength. In the C++11 edition of his book, The C++ Programming Language, Bjarne Stroustrup writes, "Please remember that those libraries and language features exist to support programming techniques for developing quality software. They are meant to be used in combination--as bricks in a building set--rather than to be used individually in relative isolation to solve a specific problem.". This is exactly what this book and its recipes are about. All the recipes in this book are designed to be as near as possible to real-life problems, while at the same time, they do not rely on any external libraries other than the STL. This way, it is very simple to play around with each of them, without having to do confusing setup work. I really hope that you find inspiration in the recipes and, maybe, find some of them to be nice standard building blocks for solving higher-level problems with this great programming language.

How to check and return value of state object array and use that to identify which object to take data from

Asked 2021-Sep-22 at 15:50

The Aim: Use the value of i.id from the mapped components when clicked on to search state ids and locate the object which contains the same id value... When this object is found to return/update id and active values.

Clicking on the dynamic rendered component triggering onClick to change value of the current active: true to active: false and find object with id of the clicked component and this.setState({active:value}) in that object. Then if (active === true) render iframe containing the object's id value.

It is not entirely clear what you are asking, do you just want the first id that is "active"? Or an array of "active" ids?

If it is just the first then simply loop over them, and return the correct id if active is true.

You'll need a browser to render the javascript and then extract the rendered HTML. Try selenium. It lets you manage a browser through your python code and interact with web page elements.

How to create a Postman server mock for uploading file and doing some uploading test of Flutter code?

I'm trying to connect to a printer server to be able to save the printing files directly in the printer storage. I'm able to do it using the curl curl -v -H 'Content-Type:application/octet-stream' 'http://192.168.1.125/upload?X-Filename=model.gcode' --data-binary @model.gcode Now I'm trying to add this function to a Flutter app but don't works....

QUESTION

Is there a name for this 3D printing effect?

Asked 2020-Sep-25 at 15:21

I'm relatively new to 3D printing, but I've taken to it with much gusto. I wish I'd done this years ago.

Trying to solve a printing problem, and I've been stymied by not knowing the name for the effect I'm seeing - there is zero chance I'm the first one to discover this.

A minimum reproducible example is a triplet of vertical cylinders on a raft, it's clear that the tool path starts at one spot, runs a full circle around to end in that same spot, and it lingers long enough to extrude just a tiny bit more material that builds up in a vertical line.

This matches exactly the tool path shown in the slicer and this effect is repeatable no matter how many parameters I changed. I've done many dozens of test prints and am not getting anywhere.

These are 16mm across and are used as inserts into a tray holding vials to shim a narrower diameter tube, and the bump is enough to matter. I have to make thousands of these and am hoping not to have to file them all down by hand.

If it matters, I'm using a Sindoh 3DWOX 2D and a 3DWOX 1 with PLA filament.

Is there a name for this effect?
Are there mitigations?

I'm starting to rethink this whole approach...

...

ANSWER

Answered 2020-Sep-25 at 15:21

I was happy to find my own answer elsewhere.

First, that effect is known as a "seam", and one mitigation is known as "vase mode" (known in some slicers as "Spiralise Outer Contour"), which builds the cylinder in a continuous spiral from the bottom up with no seam. It can create really nice aesthetically-pleasing prints.

However, vase mode only works for a single model because stopping (and possibly retracting) to print a second model breaks the whole continuous-spiral thing.

So, if I had only a few of these to print, I'd do them one at a time, but given that I need thousands of them, I've found other approaches to solving the problem.

I have a Python dictionary with dictionaries nested heavily within. There are several tiers.

What I am trying to accomplish is a function where I can enter any one of the "subcategories" values, for example, 20003482 or 200000879 and it has to return the first nested subcategory key, so for the above examples, 100003109
