pgcrypto and password hashing
tk flag

I'm thinking about my choices regarding how to store passwords in Postgres.

One such option is to use pgcrypto. Reading their docs, I see that their crypt and gen_salt functions do not use sha256 but instead use custom version of the cryptographically broken md5. Why would Postgres developers use such a hashing algorithm for their password storing module given that it's not secure?

I suppose I sho ...

Use Core Switch as an L2 Access Switch
jp flag

Can I use a CORE switch as an ACCESS Layer 2 switch? The end goal is to connect all servers through at least a 10Gb network. The servers each have high volumes of data that will be transferring back and forth to and from each other. Slower networks and internet access are not in the picture. The data transfer is strictly between the servers that would be connected to the CORE switch. Each of the mot ...

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.
