Boot screen crashed

Repairing Windows doesn't help. But I do have access to some very basic command prompt. I tried reverting the update via the DISM command.

Renewing LetsEncrypt Certificate stops Apache based web site from working

I received an e-mail recently from LetsEncrypt telling me my website certificate was about to expire - I configured the website to use HTTPS only. The certificates were auto-renewing without any problems until now. I upgraded the OpenSSL libraries on my Ubuntu 18.04 to use the latest TLS, version 1.3. It all seemed to work fine but accessing my website using a Firefox web browser running on Windows 7 di ...

How to prevent public access to GKE Ingress and make it accessible just for Apigee X
us flag

I am new in Cloud stuff, and my question may be basic, but this problem has bugged me for a week, and I don't know how to fix it.

I deployed my first Cloud project on GCP using GKE. After that, I used Kubernetes Ingress to expose its service. On the API gateway side, I used Apigee X. And successfully created a proxy and used the Ingress's IP address as the proxy's backend. Up to now, everything i ...

Is there a difference when the options order is changed between this 3 rules?

Test for no 404 error before enabling RedirectMatch?
jp flag

I have a RedirectMatch to a remote server in my Apache httpd.conf file. However, sometimes the remote server gives a 404 HTTP response. Is there a way for the Apache server to ping the remote server first and, if it doesn't give a 404 response, only then enable the RedirectMatch, such as by wrapping some kind of <If> statement around the RedirectMatch?

PowerShell Call Restore Point in Windows Beside Sequence ID

So I'm aware that using Restore-Computer -RestorePoint ID I can call a specific restore point in my script, where Windows will rollback to. My situation requires a different approach, which I've seen no documentation on.

Assuming I have 50+ clients, all which have a certain Restore Point on date JAN-XX-2021 and Description of "My Primary RollBack"... I realize each client with that restore date can  ...

Apache reverse proxy with self-signed certificate

I run a Unifi hardware appliance which comes with a self-signed certificate, issued on unifi.local. For my current setup, it's not an option to import a certificate on the appliance directly for several reasons, so I tried to get rid of the invalid certificate message of my browser by using an apache2-based reverse proxy which provides access to the appliance under another domain, secured by a Letsen ...

Is it safe to use dmcrypt on top of software raid?
in flag

I'm designing a machine, to serve as a NAS. My interest is hobby-level.

I would use mdadm to software raid a couple of same-size hdds. At first I'd use raid1, but in the future I'd add another disk and convert it to raid5. My understanding is that mdadm can do that in-place. (Yes, I know I should back the data up anyway, first.)

I would use bcache with this raid array, and an ssd, to improve per ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
