on SQL

wish me luck

not gonna study

SQL is easy

not gonna study

All you need to know about sql is how it works: 1 cartesian Product of the tables in FROM 2 sql discard all the rows that doesnt match the conditions in WHERE 3 it make groups from the table based on columns that appear in GROUP BY 4 every group return 1 row with the columns In GROUP BY 5 discard the rows returned in GROUP BY according to the conditions in having 6 sql order the rows based on the columns with ASC or DESC that appear in ORDER BY 7 print the rows in SELECT

thank you dudes!

wish me luck

Best luck

thank you dudes!

I guess you know what the order of the sentences are, and i have supposed that you havent study the drop,update,etc... Sentences that are used to manage the databases

And Good Luck

may I ask a thing about SQL?

and queries'

?

Hello everyone

hi

Hi

Anyone here working on C++ graphic maths?

Anyone here working on C++ graphic maths?

I play with that many years ago

Hi ΔNicolalala & @Daniel Saguez.

I play with that many years ago

I'm pretty new (noob) with C++ but have worked on other language like python. I work in the visual effects industry and i'm thinking of small pipeline tools & apps for VFX. How do I begin?

For example we use a lot of cad like features and tools in VFX.

You need to work with a lot of precision or better for you is numeric simplifications?

For presition I recommend https://en.wikipedia.org/wiki/SymbolicC%2B%2B

I'm quite confused with how to even begin. How do I even begin learning c++ graphics and writing basic apps.

maybe try with https://www.udemy.com/learn-c-game-development/

https://en.wikibooks.org/wiki/Guide_to_Game_Development/The_Programming_Language/C%2B%2B

There are numerous opensource libraries like ocio, ofx, boost, qt, openexr, libtiff, opengl quite widely used in our industry.

draw mathematical function have tricks, but many of them are solved for game developers many years ago with ingenious tricks

Can I ask you a question if you don't mind?

I my opinion Boost is the best libraries for C++, in any case you need to learn at least some parts of boost

Can I ask you a question if you don't mind?

sure

Suppose you want to implement a bspline function that draws a basic bspline on mouse event (click) with all the vertex points visible and also be editable by moving the vertices. How 'all you implement it. (I hope this is not too difficult)

it's tricky, are you choose graphics library ?

if you choose Qt, in this case already have somethings to use

The devs at my company have already implemented it and much more complex features using qt & boost library.

surely with GTK, but in others you need to implement more things

*not my company, I meant workplace

it's a good option Qt

http://doc.qt.io/qt-5/qeasingcurve.html#Type-enum

They wrote their own custom functions or classes to draw bspline shapes, rotate, scale, transform and many more image processing modules/classes.

Since the software is proprietary. I can only guess.

try to reuse code, start a new one, most the time is useless

with Qt you can create proprietary software

I want to be able to write such small image processing apps in c++ & qt.

The C++ graphics book I bought only talks about the maths (in numbers & formulae) and not the implementation in C++. 😢

you can read this project http://qtocc.sourceforge.net/

anyone understand genetic algorithms

and then create new with your own code and needs

you can read this project http://qtocc.sourceforge.net/

Thank you i'll read this and also try to understand the boost lib.

I'm quite confused with how to even begin. How do I even begin learning c++ graphics and writing basic apps.

I did my own 3D game engine, start with SFML (2D lib) then learn OpenGL

You can still use SFML for event management, sockets and resource loading while rendering with pure OpenGL (glew)

SQL test done It was so damn easy

Hey @Isc30

hey :D

do i know you?

can anyone message me for some paid work

what

Try upwork.com or freelancer

Lol yeah but he is developing contract for bank App and he has no know how .. I would avoid that app for sure

Hi!

Lol yeah but he is developing contract for bank App and he has no know how .. I would avoid that app for sure

In Spain things like that are the bread of every day, you see a lot of company a contracts company b, company b contracts company c and company c contracts a guy that probably doesnt hace knowledge about that

Ohh but that's risky model I think for bank applications

Here also like that model...

you write smart contract? if yes which lang. do you use?

Just learned, but I write in C/C++ for the moment

you dont ! write !

Anyone has idea about "how to draw basic editable shapes on mouse event using C++ in qt?"
