How to switch codesign certificates on Electron App for Mac (OSX)

Level of difficulty Medium

Awaiting invitation

When you have an electron app that originally was distributed with a certificate for an individual developer. And you would like to sign the next update to that app with a certificate from your organization. It will break an auto-update installation process because codesign requirements aren't met.

So, to prevent this issue, your next app version should include information about both certificates (old and new). All future app versions can be signed with the new certificate, and the auto-update process will not be disrupted.

See the example below.

10 things you may be asked about at UX Designer job interview

Level of difficulty Easy
Design Interview
Awaiting invitation

Any job interview is quite a stressful event, especially if you’ve graduated just recently and don’t have enough experience in communicating with hiring managers. Another problem is, interviews may be conducted differently in different companies: for example, employers may ask various specific questions depending on the position you are applying for, so there is no way to get 100% prepared for anything you may be asked. However, the list of general questions that HRs usually go through before switching to more specific ones are usually pretty standard, and they are aimed at getting to know you as a person and a professional. We’ve collected a list of a few most common topics that you’re most likely to be asked to talk about at a UX designer job interview — let’s discuss them.

Basic info about yourself

The question “Tell us about yourself” is the basis of any job interview. It allows recruiters to understand who they’re talking to and why you’re applying for this job. Here you are expected to present yourself in a concise, but effective manner by telling about your education and working experience, what inspires you professionally and why you would like to pursue a career in UX.

Basic knowledge of UX design

No matter how many degrees you have or how high your experience level is, your recruiters need to evaluate your knowledge of UX design as a whole. But keep in mind that a job interview is not an exam, so here you are expected not to recite the textbook definitions learned by heart, but rather share your personal understanding of UX and your role as a designer in general. Consider talking about how you define UX, what creates value in the design, what are the necessary parts of a UX design process, what are the current trends in UX. You might also be asked to explain the difference between UI and UX to see how you understand the role of each in the development process.
