Cloud setup for occasional high to extreme CPU-intensive tasks (instant vertical scaling?)
in flag

I have a business workload that has very low CPU-usage most of the time, and occasionally needs to burst to very high CPU-usage. It currently runs on a dedicated server with 32 cores, but was hoping to transition to a cloud hosting solution. The demands are roughly:

  • 1 core most of the time
  • 32 cores approximately every 20 minutes on average for about 30 seconds (not pre-determined intervals, and needs  ...

Why is AWS S3 Object count is measured iin units used to measure file size?
in flag

In AWS, the files/objects are stored in S3 bucket and the files/object count should list the total no of files/objects stored in S3 bucket as an INTEGER value.

But I see the S3 object count as floating value and the unit represented is letter 'G' like below in AWS S3 dashboard. Why is the unit used to represent object count has the unit used to represent the file size? if this is not the unit lik ...

Spin up all raid drives at the same time
ph flag

Here is the configuration:

  • 4 HDDs in a RAID-5 array (mdadm)
  • hdparm spin_down_time set for all disks
  • Debian jessie 8.11

When the drives are in standby mode and the RAID array is requested, they wake up "sequentially", one after another.
It makes the access delayed for many seconds.

Is there a way to make all the drives spin up at the same time ?

Using stunnel as proxy between SSL versions for SMTP with STARTTLS
in flag

I have a quite old software which doesn't support TLS 1.2. However SMTP Server only supports TLS 1.2.

Now I wanted to use stunnel to connect to SMTP server and and also listening for smtp access. I have already a valid certificate for this server. Before configuring different TLS versions I only wanted to test if this "stunnel proxy" works in general. I use Thunderbird to connect to :587 In [TLS_ ...

Can you enable certificate authentication in ADFS for devices *only* so that users don't receive a certificate prompt in the browser?
cn flag

Everything is in 2019 functional level.

We host our ADFS WAPs in Azure. Because the Azure servers are registered in Azure AD, they have the Azure DRS CA in the trust chain, and so the WAPs are willing to accept registered device certificates for any workstation, even though those devices aren't actually registered in our tenant. This has a side-effect of prompting users for certificates that the s ...

Server 2016 DNS // Forward DNS request to parent domain if not available in subdomain
sd flag

Is it possible to forward DNS requests to the parent domain (managed by the same server) if there's no entry in a subdomain?

Eg. requesting foo.nyc.acme.lan would automatically forward to foo.acme.lan if there is no foo in the nyc.acme.lan zone.

Installing a PFX with bundle-ca included, do I still have to install the ca-authority in root?
br flag

I have a Windows web server, and usually I install the ca-authority in "LocalMachine\Root" and the intermediary PFX certificate in "LocalMachine\My", everything works well. Now I wonder, if during the PFX certificate generation I include the ca-bundle, can I avoid to install the ca-authority in "LocalMachine\Root" and just install the PFX with included the bundle-ca in "LocalMachine\My"?

Do I need to use the bundle-ca when generating a pfx?
br flag

I just bought a "Positive SSL certificate". The crt files and bundle-ca from the issuing company (Sectigo) arrived via email. To generate the pfx I use the "PEM TO PKCS #12" from this site https://decoder.link/converter. Is it necessary that in "Bundle File" I insert the bundle-ca received? The pfx certificate is still generated even without inserting it, so I wonder what is needed and if excludi ...

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.
