I am getting:

Apache 2 Test Pagepowered by CentOS

So, the Wordpress page isn't being served by Apache, but I don't know why. I am using CENTOS 6, and I just used a puppet config to deploy it, so I am wondering why it's not working. I used the same configs before and it didn't work and my colleague did something to fix it, but he didn't share me the details. I did sudo service httpd start, but I am thi ...

What legitimate reason would an IT Admin have for requesting a user's password to setup a new laptop with Windows 10?
ng flag

The IT admin person where I work is currently setting up a new laptop for me and they've asked for my user password so they can finish the job. I'm obviously uncomfortable with that.

I suspect not, but is there any reasonable reason to need this information from me? And if not, is there a plausible reason why an inexperienced admin might prefer to just log in as me?

Postfix sender sender_dependent_relayhost_maps null sender/auto reply
jp flag

I hope somebody can clarify somethings about Postfix sender dependent relayhost in postfix for me.

We are having some problems with null sender mails and auto replies not getting relayed to the correct host.

We need our postfix to handle these mails, and send them to the correct host based on the senders @domain.com so our SPF and DKIM is handled correct.

Recover BTRFS? bad magic on superblock on /dev/md2
cn flag

so after a recent power outage my DS718+ RAID crashed.

After investigation with Syno Support we also identified that my RAM was broken (already removed) and as it was not a officially supported RAM module they now will no longer help me with recovering my RAID (thx for that) because they suspect the broken file system came from that and not from the power outage.

I do have a backup but it's quiet ol ...

block outgoing traffic on specific port without blocking internal traffic
in flag

I'm hosting a service on port 3000. Using apache, I made it so https://git.mywebsite.com proxies over to http://mywebsite.com:3000. Now, if I input the following command:

sudo iptables -A INPUT -p tcp --dport 3000 -j DROP

It does prevent external users from accessing http://mywebsite.com:3000, but now apache can no longer access it internally as well, which means https://git.mywebsite.com is down also. I ...

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.
