load balancing over single NIC to overcome per-connection limit
ru flag

I have a strange setup where the ISP provides a very fast connection (10 Gbps) but limits each connection to 50 Mbps. This is fine for multi-threaded applications where I can just boost the number of threads. But I would like to solve this problem for single-threaded applications as well. I am running Linux and this is all TCP traffic (has to be) - I feel like there is a good way to do this using iptabl ...

Pacemaker Virtual IP is still pinging
cn flag

I am having two node pacemaker cluster, with one virtual IP which is 192.168.3.100.

The virtual ip is the part of cluster resource, when I stop the cluster using pcs cluster stop --all.

I am still able to ping the virtual ip i.e. 192.168.3.100.

I believe the VIP should not ping if cluster services and it's resources are down, or am I doing something wrong here.

Please advice.

Use Apache remote IP, but require proxy IP to be in range
in flag

I put my locally hosted sites behind Cloudflare for an added layer of performance.

To restore the original connecting IP, I use mod_remoteip, set up with all of Cloudflare's IP ranges.

I also want to set up a site purely for access through Cloudflare Access, restricting access to anyone attempting to connect bypassing Cloudflare Access.

I've read online that you can do this with rules such as Require ip ...

How to troubleshoot 400 Bad Request "client sent invalid method while reading client request line"

The client makes a number of background requests, one of which is failing with 400 Bad Reqest whenever it attempts to negotiate the SSL connection.

The legacy infrastructure that I am working with is based on GFS2 and LVM2. Unfortunately, the raid-10 option for LVM appears to only allow one journal for GFS2, when I need more. I s ...

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.
