  • More Time to Certify

    With all of the shutdowns and quarantines with the COVID-19 pandemic, Microsoft has extended their deadline to finish the MCSA, MCSD, and MCSE certfifications. Previously old certification exams were due to expire on June 30, 2020. You had until then to complete your work. Now the timeline has been extended to January 31, 2021. This gives you more time to earn the cert you started.

    I haven’t held an active certification for years. I found them useful for studying and focusing my learning early in my career, but less so now. Working towards a test is also a time sink for me, when I often don’t quite have as much time as I’d like to get other things done. Life is busy, and I haven’t been as focused in a single area in a long time.

    However, I do think that certifications can be helpful in a few ways to many people, in addition to focusing your learning. Scheduling an exam puts pressure on you and will drive you to learn more. The semi-vague requirements will force you to learn more things than you might otherwise work on, which broadens your knowledge. I’ve found that to be particularly helpful in my career, when I have a wide variety of skills in different areas. I can often solve more complex problems.

    Maybe the one area that you can use to further your career and open doors is to point to the certification not as a measure of knowledge and skill, but of desire. It takes active effort to learn and pass a certification exam, and employers need people that are hungry to learn and grow, and most importantly, willing to do this on their own time. It’s a good point to make if you talk about your work in an interview or write something on your blog.

    In addition to extending the deadline, Microsoft has changed the fees for rescheduling and cancellation, which is good. They’re also working for more remote proctoring of exams, which will allow more people to take these tests from work or home instead of having to drive to a facility. They are also extending out voucher and discount dates.

    If you’re interested in pursuing something, let us know today. I’m considering some of the Azure role based certifications, mostly because they may focus my learning. Now I just need to find time and make the decision to actually move in that direction.

  • Encryption Libraries

    One of the ways we work to implement better security is through the use of encryption. I remember the early days of PGP, VPNs adding end to end encryption, IPSec becoming available, and more. I was excited to see column level encryption come in SQL Server 2005, but it was a bit complex to implement and had issues. The evolution over time with TDE and Always Encrypted were welcome additions, but we can do better.

    Handling encryption in the database can provide some protection, but really, we’d like to see an end to end solution, that ensures data is protected on the wire as well as in the db. Microsoft does a lot of research, and released a Simple Encrypted Arithmetic Library (SEAL) as open source code. This is a C++ library that developers can use to protect their communications. Last year they also released a .NET wrapper to make it easier for a wide variety of developers to use.

    There is a lot more to deal with when handling encrypted at scale. Indexing and search operations are difficult and complex, and can require lots of resources. I think that the Always Encrypted in SQL Server 2019 with Secure Enclaves is a good evolution, but it’s complex to set up, tooling is poor, and maybe more disconcerting, there are potential vulnerabilities with secure enclaves on Intel chips.

    Certainly a combination of developers being able to use something like SEAL and a linkage with a secure enclave on the server for set-based operations might be something we can look forward to in the future. I hope so, as security continues to be a challenge for many of us.

    I’d also like to see more software that is built to ensure users can’t access huge amounts of data, and perhaps easier ways to control the export of large amounts of data. We do need this capability, but we also want very few people, or no people and only a process, with rights to do so.

  • Have You Made a Difference?

    On New Year’s Eve, I was reminiscing about the past decade. I started posting some pictures on Twitter from the past decade, which were really memories for me of what had happened in life. Later, I saw this tweet from the Pittsburgh Pirates, quoting the late Roberto Clemente, a renowned humanitarian. The quote is:

    “Any time you have an opportunity to make a difference in this world and you don’t, then you are wasting your time on Earth.”

    The world is in a crisis. Whether you think we are over- or under-reacting, making good or bad choices, or anything else. The reality is that we are fighting a pandemic throughout most of the world, many of us are isolated at home with limited contact with others. Many people are struggling with health concerns, financial issues, job security, and other issues. It’s not just their own personal struggles, but the struggles of others can affect us. Loneliness is certainly a big issue for many, even those living with others and missing their routine.

    Have you made a difference during this time to others?

    It’s a simple question, but it’s one that weighs on my mind. I wish I were a medical professional and could volunteer. I wish I were trained as a first responder and could do something. I’d be happy to go move boxes or otherwise help people working long hours to help others. I’m somewhat upset and guilty because inaction and reducing the spread is more important than my feelings.

    I’ve tried to make a difference in a few ways, with the daily coping in the newsletter and my own blogging for the things I’m trying. I’ve hosted some video calls at T-SQL Tuesday live, just providing a space to touch base with friends and the rest of #sqlfamily. I’m proud my company is trying some things and reaching out the community, without an ulterior motive. Our CEO passionately asked that we do things for the community without regard to sales, customers, or any Redgate purpose other than giving back.

    This is a time to pull together and help others. Many are scared, many are worried, many are dismissive, but even more are struggling. What can you do to help someone else this week?

  • Have You Deployed an Availability Group?

    The last few weeks have been interesting, to put it mildly, with both more and less engagement online. I see more people holding video calls, both inside and outside of work, but I also see less engagement at SQLServerCentral, blogs, Slack, and some of the more common community tools we’ve had. I suspect this new way of working is strange, and it’s upset many of the rhythms that people have built over the years.

    In any case, one very important and common technology in the SQL Server platform is an Availability Group. This technology has been in the product since 2012, and unlike clustering, it’s relatively easy to set up. Not to say it’s easy, and you do need to develop some skills outside of T-SQL to understand how this works. This week I’m wondering how many of you might never have done this?

    Or maybe you’ve done it once or twice and forgotten about it.

    While we’re dealing with the various challenges of a pandemic, this is also a time where you might brush up on a few skills or learn new ones. Deploying, configuring, and testing an AG is something that is valuable to both DBAs and developers, and it’s a good skill to bring to your next interview. Every employer wants to know you understand HA/DR.

    We have a Stairway Series that can help you along with quite a few articles and blogs that people have written. There are various lab posts as well, including a good one from Ryan Adams, that can help you get started. If you don’t have equipment handy, you can build one in Azure for cheap, and even turn off the VMs when you’re not using them and spend just a few dollars a month on storage. That’s not much cost to build a valuable skill in your career.

    If you’ve built a lab, maybe you want to tackle something complex, like the scenarios that Allan Hirt writes about on his blog. If you’ve never done one, maybe try to build one, take notes and capture screenshots, and blog about it. In Word if you want to start a portfolio to send out with your resume, or on your live blog. It might be a good time to start a new blog.

    Focusing on a project like this can help shut out some of the noise in the world and engage you in a new way with your career. Hopefully you are doing well, and life is proceeding for you. If not, maybe tackle a project to take your mind away from things, and check out our daily coping tips in the newsletter.
