After fuming for a few minutes I thought of a workaround, and it worked. If you need to get into the crappy Java web app on Carelink and you are using a Mac updated to High Sierra and Safari, this works. Go into the Preferences Menu in Safari and select the Advanced Tab. At the bottom, you should see the Show Develop Bar in Menu option. Chess gui uci mac free download. ChessX A free and open source chess database application for Linux, Mac OS X and Windows.

I recently picked up a Yubico U2F hardware key and thought I’d try to create a web application that was protected with two-factor hardware-based authentication. Things were going smooth until I realized that it is mandatory to be using HTTPS within your application, even when testing locally. HTTPS is common, but I’d never actually set it up with Node.js because I had always been using services like Cloudflare that configure it for you. The problem is that these services are for live domain names, not necessarily localhost.

While we’re not going to explore U2F hardware keys in this tutorial, we’re going to take a look at creating and installing a self-signed certificate for use in Node.js within macOS.

Creating a Self-Signed Certificate

Before we tell Node.js that we want to use a self-signed certificate for testing on localhost, we need to actually generate that certificate. If you’re on a Mac and you’ve already got your development tools installed like Xcode, you should already have the necessary command line tools to be successful.

From the command line, execute the following:

The above commands will do two different things. The first command will generate a private key to be used when creating your certificate in the second command. In the second command, we generate a certificate that expires after a a year. The above commands are not specific towards generating a localhost certificate, but they are for a self-signed certificate. To make the certificate localhost compatible, it is important that you use localhost as the common name when prompted by the second command.

Don’t lose the .key file and the .cert file as both will be necessary when configuring the Node.js application.

Installing the Certificate in the macOS Keychain

With the .cert file in hand, the next step is to install it as a trusted authority on macOS. To do this, you’ll need to open your Keychain application.

In the certificates tab, drag your .cert file into the window. You may be prompted to enter your computer password and if not, you will be prompted later.

With the certificate added, we need to change the trust so that way it is actually used by our web browsers. Double click on the certificate entry to be brought to a new window with the certificate information.

Because this certificate is self-signed for localhost testing, it is easiest to choose the dropdown and select to always trust what the certificate has to offer. If you are more comfortable choosing only what you need, go for it. When you close the window after making the change, you may be prompted to enter your password.

With the certificate generated and in place on macOS, we can work towards using it in Node.js.

Developing an HTTPS Secured API with Express Framework

We’re going to build an incredibly simple RESTful API with Express Framework that uses our self-signed certificate. If you’d like more information on creating APIs, you might check out my previous tutorial titled, Create a Simple RESTful API with Node.js, or even my in-depth eBook and video course, Web Services for the JavaScript Developer.

On your computer, create a new project directory and execute the following commands:

The above commands will create a new Node.js project and install the Express Framework package. What you’ll also need to do is create an app.js file or some other JavaScript file to hold our application logic. Within the app.js file, include the following:

If you’ve ever worked with an Express Framework API before, the above code should look very familiar. At the top you’ll notice that we’ve imported the https and fs dependencies, both of which are readily available out of the box in Node.js. We have a single endpoint, which will be served over HTTPS.

To make our application HTTPS, we need to use the https package and read the .key and .cert files from the disk. You’ll want to provide the path to your files because the above code assumes that both files exist in the same directory as the app.js file. Finally it might be a good idea to use the typical HTTPS port which is 443.

When you run this application and navigate to https://localhost/ in your web browser, Chrome or similar might throw an alert about the destination being unsafe. This is because we’re using a self-signed certificate and Chrome or similar might not recognize it as a safe authority. Go ahead and choose to proceed anyways because we know what we’re trying to accomplish.

Conclusion

You just saw how to generate, install, and use a self-signed certificate in your Node.js application running on localhost on a macOS computer. The process of installing a self-signed certificate may vary between Mac, Linux, and Windows, but the generation and usage in Node.js should be more or less the same.

PolyGlot,
an adapter ^[2] that allows UCI engines to use interfaces and GUIs supporting the Chess Engine Communication Protocol, developed by Fabien Letouzey and modified by Fonzy Bluemers^[3]. Polyglot is open source, licensed under the GPL, and is able to run on various operating systems, which allows to run UCI engines not only under Windows with its native chess GUIs, but also under Linux and Mac OS using XBoard. PolyGlot 1.4 provides a simplistic opening book implementation, referred as bin-opening book format.

As far as XBoard/WinBoard is concerned since 2018, Polyglot is scheduled for retirement. The latest beta package of WinBoard did not contain any Polyglot, but relied on UCI2WB instead, which is variant agnostic, and supports all UCI dialects (USI, UCCI, UCI-Cyclone, Arena960). Polyglot is useless for anything other than ordinary Chess ^[4].
