Setting up passwordless Linux logins using public/private keys

Setting up an account on a Linux system that allows you to log in or run commands remotely without a password isn’t all that hard, but there are some tedious details that you need to get right if you want it to work. In this post, we’re going to run through the process and then show a script that can help manage the details.

Once set up, passwordless access is especially useful if you want to run ssh commands within a script, especially one that you might want to schedule to run automatically.

New Linux System Call Proposed To Let User-Space Pin Themselves To Specific CPU Cores

A “pin_on_cpu” system call has been proposed for the Linux kernel as a new means of letting user-space threads pin themselves to specific CPU cores. User-space processes requesting to be run on specific CPU cores can already e done by the likes of Linux’s sched_setaffinity to get/set the CPU affinity mask while pin_on_cpu would be a new and simpler way. The current calls also run into issues around CPU hot-plugging, as explained further in the RFC mailing list post.

Setting the CPU core to run on with the proposed pin_on_cpu system call would still require that the specific CPU be part of the allowed CPU mask.

13 of the best React JavaScript frameworks

React.js and React Native are popular open source platforms for developing user interfaces (UIs); both rank well for desirability and use in StackOverflow’s 2019 Developer Survey.

The following are 13 of the best React JavaScript frameworks; all are open source—the first 11 (like React) are licensed under the MIT license and the latter two are licensed under Apache 2.0.

Why UK leaders need open technology for the disrupted future

We’re not quite past the post with Brexit, but thankfully, we have moved beyond the Brexit hiatus. And, it’s time we did. Whatever your views on the merits of Brexit, as the UK’s Prime Minister has stressed, it’s time to move on and move forward.

It is a task that all business leaders in the UK need to embrace. By seizing the moment to “get open done”, we can not only develop and sustain the UK’s leadership in open technology, but also carve out our status on the world stage for many years to come.
