As companies sent their people packing and working from home, they included company gear for them to work on. However, many people have their own personal computers at home.

To support the simultaneous use of multiple systems, developers created software such as Synergy. By using these applications, you can use one mouse and keyboard across multiple computers without having to plug and switch devices.

So aside from Synergy, what other options are there? Here are the five best apps for sharing a mouse and keyboard across different systems.

1. Share Mouse

If you have two computers at home, you can use Share Mouse to control both systems with whatever connected keyboard and mouse you have. No matter if you’re on a Mac or a PC, the peripherals on both systems can crossover to the other device.

For example, if you have a Windows device and a MacBook Pro, you can use the trackpad on the keyboard and trackpad on your MacBook to control your Windows device. It also works vice-versa, with the Windows PC peripherals working on your Mac.

You can use the Share Mouse app as long as both computers are on the same network. It’s free for personal use—but is limited to a maximum of two computers/two displays only. If you want to use the software on up to nine devices, each with up to four monitors, you have to purchase the Pro version.

When you get the Pro version, you also get additional features like locking and unlocking all connected devices simultaneously, synced screen savers, and even remote log-in. Best of all, every Share Mouse licenses have a portable version so that you can use it on other computers without extra installation.

Download: Share Mouse for Windows and Mac (Free, other licenses available)

2. Input Director

This free, powerful, and feature-rich software keyboard, video, and mouse switch (KVM) offers a range of keyboard, video, and mouse switching options. However, it is only compatible with Windows 10, Windows 8/8.1, and Windows 7. This app won’t work with Apple or Linux systems.

What separates this from Share Mouse is that all its features are available for the free version. It offers multi-monitor support, key-bindings, macros, and even enhanced security options.

You can limit which computers can control your Input Director app by name, IP address, or even subnet. And if you’re planning to employ this in a network to which several other users connect, you can encrypt your data to keep them safe.

Again, this powerful app is free for personal use. But if you want to employ this in a commercial and corporate setting, you have to contact the maker.

Download: Input Director for Windows (Free)

3. Mouse Without Borders

Mouse Without Borders is a side-project created by Microsoft engineers under the company’s Garage program. Likewise, while this is not an official Microsoft product, it is developed and supported by its employees and is recognized as such. However, because of this, it’s also available for Windows devices only.

It’s even available for download on Microsoft’s Garage, the platform designed to push software innovations from their employees and customers. Furthermore, support for its use is available via Microsoft’s Community Forums.

Like the other KVMs above, you can share one keyboard and mouse across four computers connected to the same network. You can also set custom shortcuts to make it easier for you to navigate across devices.

The single greatest advantage this app has over the other options is its relationship with Microsoft. Since their engineers and programmers created this app, you can expect fewer issues with the operating system. The developers are already familiar with the app’s working environment to issue updates ensuring compatibility faster than other third-party software companies.

Download: Mouse Without Borders for Windows (Free)

4. Multiplicity

This app is one of the more powerful software KVM options. Although it’s only free to try, the paid licenses will let you do so much more than just controlling multiple computers through one keyboard and mouse set.

The KVM and KVM Pro licenses allow you to stream multiple computers on a single monitor. And all licenses can connect to any computer, whether connected to your local network or via a VPN. So even if you’re physically distant from a device, you can use it like it’s right in front of you.

Audio sharing is also enabled across all licenses, so if you play an audio file on one slave device, the sound will output on your main computer. And with Multiplicity, your control inputs are not limited to keyboard and mouse. It also accepts hot-key and touch switching for touchscreen computers, allowing you to use it even with Microsoft tablets and 2-in-1s.

Download: Multiplicity for Windows (Free for 30 Days, Purchase Required)

5. Barrier

When using multiple systems together, like Mac, Windows, and PC, you’re bound to run into some compatibility issues. So if you want to use KVM software, it could be challenging to find an app that will work well on all three different operating systems.

That’s where Barrier comes in—it’s a free, open-source KVM software based on the popular Synergy app, which was itself based on the original CosmoSynergy program by Chris Schoeneman. But unlike Synergy, Barrier is a no-frills app designed to work simply.

It only has two features: it lets you control multiple computers with one keyboard and mouse, and it shares clipboards across your devices. But since this is an open-source project, you can tweak the program to your needs if you’re into programming.

So if you want to connect your PC to your Mac for free or connect any system to your Linux computer, Barrier is the only solution for you.

Download: Barrier for Windows | Mac | Linux (Free)

Control Multiple Systems With One Keyboard and Mouse

Software KVMs are helpful for automatically connecting multiple devices. You no longer have to press a switch or turn a dial just to control your other device. Having this will save you both time and desk space, letting you get more done.

So whether you’re a programmer, a video editor, or even a writer, if you’re working with multiple systems a lot, a KVM app will make you more efficient.

Xinova, a Seattle company that operated a network of inventors, is winding down operations, GeekWire has learned.

Xinova spun out of Intellectual Ventures in 2016 and helped match inventor ideas with customers such as PepsiCo, Honda, Funai, and others. It billed itself as an “innovation-as-a-service” platform.

The company raised a $48 million Series A investment to scale the business and grow its network that included more than 12,000 inventors across 118 countries. Xinova would find companies that needed tech solutions; put a call out to its inventor network; and compensate inventors via upfront payment and profit-sharing agreements. Xinova would typically cover development costs and manage intellectual property. The company at one point employed more than 100 people globally across ten offices worldwide.

But Xinova needed more cash and ran into trouble when it tried raising another $100 million. The U.S.-China trade war and the pandemic caused investor wariness, and one firm even backed out of a signed funding commitment.

The company had to trim expenses, laying off staff over the past two years and cutting costs elsewhere. It again tried to raise more capital earlier this year but wasn’t able to convince investors. Xinova tried to work with its creditors on a restructuring plan but that also didn’t pan out, forcing the shutdown decision. The company now has only two employees who are helping wind down operations.

Edward Jung, who helped launch invention business Intellectual Ventures in 2000 and was an early Microsoft engineering leader, was Xinova’s founder and CEO. He said the company was able to run an “economically-sustainable business” but couldn’t renegotiate its legacy liabilities, which made additional equity fundraising impossible.

Jung resigned several months ago, citing a conflict with his position as the largest secured creditor. He said he is responsible for “taking on liabilities and risks in excess to what was sustainable through these unexpected changes.”

“I regret disappointing my most excellent investors, partners, and employees,” Jung added. “But I remain a believer in the vision of global innovation networks and am continuing this vision in new stealth projects.”

Jung launched Intellectual Ventures with former Microsoft technology chief Nathan Myhrvold. In 2007, Jung began heading up the firm’s “Invention Development Fund,” which was spun out in 2016 as Xinova.

Xinova spun out its own standalone company called Allied Inventors in 2017 to help manage intellectual property assets. We’ve reached out to Allied to learn if it is still in business. Tom Kang, who previously led Xinova, is CEO of Allied, according to the company’s website.

Xinova in 2019 launched a joint venture called Arcnet, an online capital marketplace that lets investors fund innovation projects on one platform across borders.

Xinova Asia will continue to operate. Xinova also had offices in Japan, Finland, Tel Aviv, Vienna, Beijing, Singapore, Sydney, Hong Kong, and Bangalore.

As a student of programming, you’ve likely learned plenty of different algorithms throughout the course of your career. Becoming proficient in different algorithms is absolutely essential for any programmer.

With so many algorithms, it can be challenging to keep track of what’s essential. If you’re prepping for an interview or simply brushing up on your skills, this list will make it relatively easy. Read on as we list the most essential algorithms for programmers.

1. Dijkstra’s Algorithm

Edsger Dijkstra was one of the most influential computer scientists of his time, and he contributed to many different areas of computing science, including operating systems, compiler construction, and much more. One of Dijkstra’s most notable contributions is the ingenuity of his shortest path algorithm for graphs, also known as Dijkstra’s Shortest Path Algorithm.

Dijkstra’s algorithm finds the single shortest path in a graph from a source to all graph vertices. On every iteration of the algorithm, a vertex is added with the minimum distance from the source and one that does not exist in the current shortest path. This is the greedy property used by Djikstra’s algorithm.

The algorithm is typically implemented using a set. Dijkstra’s algorithm is very efficient when implemented with a Min Heap; you can find the shortest path in just O(V+ElogV) time (V is the number of vertices and E is the number of edges in a given graph).

Dijkstra’s algorithm has its limitations; it only works on directed and undirected graphs with edges of positive weight. For negative weights, the Bellman-Ford algorithm is typically preferable.

Interview questions commonly include Djikstra’s algorithm, so we highly recommend understanding its intricate details and applications.

2. Merge Sort

We’ve got a couple of sorting algorithms on this list, and merge sort is one of the most important algorithms. It’s an efficient sorting algorithm based on the Divide and Conquer programming technique. In a worst-case scenario, merge sort can sort “n” numbers in just O(nlogn) time. Compared to primitive sorting techniques such as Bubble Sort (that takes O(n^2) time), merge sort is excellently efficient.

Related: Introduction to Merge Sort Algorithm

In merge sort, the array to be sorted is repeatedly broken down into subarrays until each subarray consists of a single number. The recursive algorithm then repeatedly merges the subarrays and sorts the array.

3. Quicksort

Quicksort is another sorting algorithm based on the Divide and Conquer programming technique. In this algorithm, an element is first chosen as the pivot, and the entire array is then partitioned around this pivot.

As you’ve probably guessed, a good pivot is crucial for an efficient sort. The pivot can either be a random element, the media element, the first element, or even the last element.

Implementations of quicksort often differ in the way they choose a pivot. In the average case, quicksort will sort a large array with a good pivot in just O(nlogn) time.

The general pseudocode of quicksort repeatedly partitions the array on the pivot and positions it in the correct position of the subarray. It also places the elements smaller than the pivot to its left and elements greater than the pivot to its right.

4. Depth First Search

Depth First Search (DFS) is one of the first graph algorithms taught to students. DFS is an efficient algorithm used to traverse or search a graph. It can also be modified to be used in tree traversal.

The DFS traversal can start from any arbitrary node, and it dives into each adjacent vertex. The algorithm backtracks when there is no unvisited vertex, or there’s a dead-end. DFS is typically implemented with a stack and a boolean array to keep track of the visited nodes. DFS is simple to implement and exceptionally efficient; it works(V+E), where V is the number of vertices and E is the number of edges.

Typical applications of the DFS traversal include topological sort, detecting cycles in a graph, pathfinding, and finding strongly connected components.

5. Breadth-First Search

Breadth-First Search (BFS) is also known as a level order traversal for trees. BFS works in O(V+E) similar to a DFS algorithm. However, BFS uses a queue instead of the stack. DFS dives into the graph, whereas BFS traverses the graph breadthwise.

The BFS algorithm utilizes a queue to keep track of the vertices. Unvisited adjacent vertices are visited, marked, and queued. If the vertex doesn’t have any adjacent vertice, then a vertice is removed from the queue and explored.

BFS is commonly used in peer-to-peer networks, shortest path of an unweighted graph, and to find the minimum spanning tree.

6. Binary Search

Binary Search is a simple algorithm to find the required element in a sorted array. It works by repeatedly dividing the array in half. If the required element is smaller than the middlemost element, then the left side of the middle element is processed further; otherwise, the right side is halved and searched again. The process is repeated until the required element is found.

The worst-case time complexity of binary search is O(logn) which makes it very efficient at searching linear arrays.

7. Minimum Spanning Tree Algorithms

A minimum spanning tree (MST) of a graph has the minimum cost among all possible spanning trees. The cost of a spanning tree depends on the weight of its edges. It’s important to note that there can be more than one minimum spanning tree. There are two main MST algorithms, namely Kruskal’s and Prim’s.

Kruskal’s algorithm creates the MST by adding the edge with minimum cost to a growing set. The algorithm first sorts edges by their weight and then adds edges to the MST starting from the minimum.

It’s important to note that the algorithm doesn’t add edges that form a cycle. Kruskal’s algorithm is preferred for sparse graphs.

Prim’s Algorithm also uses a greedy property and is ideal for dense graphs. The central idea in Prim’s MST is to have two distinct sets of vertices; one set contains the growing MST, whereas the other contains unused vertices. On each iteration, the minimum weight edge that will connect the two sets is selected.

Minimum spanning tree algorithms are essential for cluster analysis, taxonomy, and broadcast networks.

An Efficient Programmer Is Proficient With Algorithms

Programmers constantly learn and develop their skills, and there are some core essentials that everyone needs to be proficient in. A skilled programmer knows the different algorithms, the benefits and drawbacks of each, and which algorithm would be most appropriate for a given scenario.
