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. ... -

Coluna.jl
Branch-and-Price-and-Cut in Julia
Coluna is a branch-and-price-and-cut framework written in Julia. You write an original MIP that models your problem using the JuMP modeling language and our specific extension BlockDecomposition offers a syntax to specify the problem decomposition. Then, Coluna reformulates the original MIP and optimizes the reformulation using the algorithms you choose. Coluna aims to be very modular and tweakable so that you can define the behavior of your customized branch-and-price-and-cut algorithm. -

Administrate
A Rails engine that helps you put together an admin dashboard
...Administrate's admin dashboards give non-technical users clean interfaces that allow them to create, edit, search, and delete records for any model in the application. Administrate solves the same problem as Rails Admin and ActiveAdmin, but aims to provide a better user experience for site admins, and to be easier for developers to customize. To accomplish these goals, Administrate follows a few guiding principles, such as support the simplest use cases, and let the user override defaults with standard tools such as plain Rails controllers and views, and break up the library into core components and plugins, so each component stays small and easy to maintain. -

NeuralOperators.jl
DeepONets, Neural Operators, Physics-Informed Neural Ops in Julia
...It learns an operator, which is a mapping between infinite-dimensional function spaces. It can be used to resolve partial differential equations (PDE). Instead of solving by finite element method, a PDE problem can be resolved by training a neural network to learn an operator mapping from infinite-dimensional space (u, t) to infinite-dimensional space f(u, t). Neural operator learns a continuous function between two continuous function spaces. The kernel can be trained on different geometry, which is learned from a graph. Fourier neural operator learns a neural operator with Dirichlet kernel to form a Fourier transformation. ... -

Restaurant Management System
Restaurant Management System written in Python using Tkinter
Restaurants nowadays require modern solutions to handle daily tasks, especially when it comes to order handling as bookkeeping is outdated for modern times, in which human fault might cost the facility lots of money. Restaurant Management System (will be referred as RMS from now on) offers the following to tackle the problem. Store the configuration of the given restaurant and its menu to easily handle reservations and orders. Create and store orders for the requested tables. Generate and save bills when requested. Storing the restaurant configuration: configure facility name, table/seat counts, and menu with the ability to modify them in the future. ... -

zustand
Bear necessities for state management in React
...Has a comfy API based on hooks, isn't boilerplatey or opinionated. Don't disregard it because it's cute. It has quite the claws, lots of time was spent dealing with common pitfalls, like the dreaded zombie child problem, react concurrency, and context loss between mixed renderers. It may be the one state-manager in the React space that gets all of these right. -

Impetus
A key remapping daemon for linux
...In order to achieve satisfactory results a medley of tools need to be employed (e.g xcape, xmodmap) with the end result often being tethered to a specified environment (X11). keyd attempts to solve this problem by providing a flexible system-wide daemon that remaps keys using kernel-level input primitives (evdev, input). -

Pkg Julia
Package manager for the Julia programming language
...If you’ve ever tried to run code you haven’t used in a while only to find that you can’t get anything to work because you’ve updated or uninstalled some of the packages your project was using, you’ll understand the motivation for this approach. In Pkg, since each project maintains its own independent set of package versions, you’ll never have this problem again. Moreover, if you check out a project on a new system, you can simply materialize the environment described by its manifest file and immediately be up and running. -

electricityMap
A real-time visualisation of the CO2 emissions of electricity
...It should provide a breakdown by generation type. Often fossil fuel generation (coal/gas/oil) is combined under a single heading like 'thermal' or 'conventional', this is not a problem. Citizens should not be responsible for the emissions associated with all the products they export, but only for what they consume. Consumption-based accounting (CBA) is a very important aspect of climate policy and allows assigning responsibility to consumers instead of producers. Furthermore, this method is robust to governments relocating dirty production to neighboring countries in order to green their image while still importing from it. -

react-big-calendar
gcal/outlook like calendar component
...Also make sure that your calendar's container element has a height, or the calendar won't be visible. Date internationalization and localization is hard and react-big-calendar doesn't even attempt to solve that problem. Instead you can use one of the many excellent solutions already out there, via adapters called "localizers". Big Calendar comes with two localizers for use with Globalize.js or Moment.js. Choose the localizer that best suits your needs, or write your own. Whatever you do, you'll need to set it up before you can use the calendar (you only need to set it up once). -

AviTab
X-Plane plugin that displays a tablet to aid VR usage
...Using a PDF reader breaks the immersion because the virtual aviator either has to take off of their HMD or use other tools that can move windows into VR. AviTab tries to solve this problem by offering a PDF reader inside a native plugin for X-Plane. Using a plugin also opens possibilities for more apps inside the tablet, for example, to display information about the plane status or aid in navigation. When hovering over the edges of the tablet from a short distance, X-Plane will display green bars around the tablet. ... -

orbit
Orbit is an issue and project tracker: create projects, track issues
...We wanted one place to plan a project, move issues through a workflow, and see progress add up, without the setup getting in the way of the work. How Orbit came to be A short path from a shared frustration to a tool we actually wanted to use. The problem Every tracker we tried asked us to configure more than we wanted to maintain, before a single issue got created. The first version One workspace: create a project, add issues, and move them through a workflow that made sense. Built for teams Roles, dashboards and notifications, so the whole team could rely on the same source of truth. ... -
