    Autodesk Fusion 360

    Autodesk Fusion 360

    Use Autodesk Fusion 360 on Linux

    Autodesk Fusion 360 is a cloud-based 3D modeling, CAD, CAM, CAE, and PCB software platform for product design and manufacturing that offers an affordable, powerful alternative to other well-known solutions on the market.But the problem is that it usually only works on systems that have Windows or macOS installed as the operating system. I'm using a Linux distribution such as openSUSE Tumbleweed and needed a solution to this problem. And so, with this nice tool, we no longer need two operating systems for Fusion 360 if you or I want to create an awesome project in the future.

    OR-Tools - Google Optimization Tools

    OR-Tools - Google Optimization Tools

    Google's software suite for combinatorial optimization

    ...This suite contains a number of solvers, namely: a constraint programming solver; a linear programming solver; wrappers for commercial solvers (like Gurobi or CPLEX) and other open source solvers (SCIP, GLPK, etc.); among others. OR-Tools is written in C++, but comes with wrappers for Python, C# and Java. Once you model your problem in your preferred programming language, you can then use any of OR-Tools’ available solvers. OR-Tools is an award-winning project, having won three gold medals in the 2020 MiniZinc Challenge, the international constraint programming competition.

    Convex.jl

    Convex.jl

    A Julia package for disciplined convex programming

    ...Convex.jl makes it easy to describe optimization problems in a natural, mathematical syntax, and to solve those problems using a variety of different (commercial and open-source) solvers. Convex.jl works by transforming the problem—which possibly has nonsmooth, nonlinear constructions like the nuclear norm, the log determinant, and so forth—into a linear optimization problem subject to conic constraints. This reformulation often involves adding auxiliary variables and is called an "extended formulation", since the original problem has been extended with additional variables. ...

    dev-sidecar

    dev-sidecar Git release

    The developer sidecar, named service-sidecar from service-mesh, means an auxiliary sidecar tool (hereinafter referred to as ds) for developers to proxy HTTP requests to some domestic acceleration channels through local proxy. Intelligently resolve the best domain name IP address according to network conditions to obtain the best network speed. Solve the problem that some websites and libraries are inaccessible or slow. It is recommended that if you encounter a slow-opening foreign website, you can first try to add the domain name to the dns settings. Block the website that cannot be opened, and proxy to the accelerated mirror site. With a speed measurement mechanism, when the access fails or times out, it automatically switches to the standby site, making the target service highly available. ...

    Scany

    Scany

    Library for scanning data from a database into Go structs and more

    Go favors simplicity, and it's pretty common to work with a database via driver directly without any ORM. It provides great control and efficiency in your queries, but here is a problem: you need to manually iterate over database rows and scan data from all columns into a corresponding destination. It can be error-prone verbose and just tedious. scany aims to solve this problem. It allows developers to scan complex data from a database into Go structs and other composite types with just one function call and doesn't bother with row iteration.

    MCM-ICM

    MCM-ICM

    Mathematical Contest resources

    MCM-ICM is a curated archive of Outstanding Winner (“O-奖/特等奖”) solution papers from the Mathematical Contest in Modeling and the Interdisciplinary Contest in Modeling, spanning the early 2000s through recent years. The repository is organized by year, with per-year folders that collect the top-ranked reports and, in later years, additional materials such as problem statements or problem notes when available. It has evolved from a single-maintainer project into a collaborative effort, with different contributors stewarding successive year ranges so the collection stays current. The contents skew toward MATLAB and LaTeX, reflecting the tools most winning teams use to build models and typeset their reports; you’ll typically see complete write-ups alongside code that implements optimization, simulation, statistical analysis, or other modeling pipelines.
