How to remove apcu and memcached from centos?
id flag

I've always installed apcu and memcached on my server, but I'm not sure how useful they are. Mostly 2-3 pages per visit are visited on my sites. And I'm not even sure if having them is a good thing or a bad thing, whether it's talking about SEO or consuming or saving server resources.

I would like to try to remove them and see what happens... But I find tons of guides on how to install them and n ...

Can worker nodes' master be replace via kubeadm join alone?

I have a single master setup with 3 worker nodes which is already being used. I need to convert the single-master to multi-master setup. I can only see the official doc where a "fresh" cluster is being setup with multi-master.

My plan is to kubeadm reset the current single-master node and then follow what's in the official doc. Keep the worker nodes running and then kubeadm join them to the new clust ...

As the topic suggests, I want to have the AD VM on Hyper-V connect to two different VLANs (100 and 200) which are different physical networks. One physical network (VLAN 100) is where all the user desktops lie (Need AD for user authentication) and one physical network is (VLAN 200) where I will forward the Event logs (Application, Security Events on the AD VM to.

How to Avoid Crazy Caching with "Vary: Cookie" Header in NGINX
ke flag

I know Vary: Cookie is not well liked, since it causes caching of every variation of cookies a user might report. On the other hand, without it, I've had to use Cache-Control: no-cache to tell my NGINX caching server to skip caching content entirely that might have a user logged in (every page of my site, incidentally, since there's an account box at the top of the page).

I only send cookies if the user  ...

I usually execute "watch -n0.1 w" to see what user is continuously doing. However, if the user executes "sudo -i", becomes root and executes something, I cannot see his activity anymore.

Take the following example: I have 3 sessions open. On first session, I am checking "watch -n1 w" to see what other users are doing. On second session, I'm executing "sudo -i", then "vim session2.txt". On third s ...

We have a large pool of devices that establishes socket connections with a server. Connections are TCP socket connections hitting a server IP: port pair from a destination IP port pair. In stand alone mode there is no problem in responding back to the devices.

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.
