TJay Belt topic for this month’s is Work/Life Balance and he asks a series of questions. I am going to go with, “What are tips or tricks can you share to help others?”
The most widely used virtual reality headset that is not connected to a gaming console is the Oculus Quest. On August 24, 2021 Oculus will make available a 128GB Quest 2 for $299. It will include the new silicon cover- no more sweaty foam and makes it much easier to clean and wipe down. I have a Quest 1 and have been patiently waiting until I dive in and get a fully-loaded Quest 2.
Besides being able to play LOTS of great games, people are getting into VR fitness. Yes- being able to work out and get sweaty with this contraption on your face.
The headset works wirelessly standalone and you can still connect it to your PC (wired and wireless – you MUST be on the same wireless network- it needs to be fast on order to connect to your PC).
I still get up in the morning, drink coffee, and draw in VR. Drawing around you with digital paint, sculpting with digital clay, take your pick.
My initial interest, and it still is, are art galleries. This link will show a demo. Those are personal photographs and they are 6 feet tall. You can walk up and see details that you simply cannot see just looking at images on a computer screen.
For those #SQLFamily members who own a Quest 1 or a Quest 2, and are interested, I’ll offer to build you a free art gallery. Hit me up on Twitter and we can chat.
For a drug and alcohol free way of checking out of reality and being able to do many things in a healthy and fun way using a bit of affordable technology has helped me cope and deal with life lately.
“How Do You Respond When Technology Changes Under You?”
As I like to say, I’ve been using SQL Server since the last millennium and I’ve seen a lot of things come and go (to echo my inner Han Solo).
While the moment you think you are an expert and there is nothing else left to learn, that’s when you are in trouble. There is ALWAYS something new to learn as one perfects one’s craft.
Only the Paranoid Survive
Years ago I read this book by Andy Grove, one of the founders of Intel called Only the Paranoid Survive. It can be summed up by looking both inside and outside of your organization and never settling for thinking you know everything about everything. It was great advice then as it is still now. Sadly the executives at Intel, IMHO, got “Fat, Dumb, and Happy”- a colloquialism meaning they allowed themselves to get comfortable and took their focus off things. Today AMD is eating their lunch in the processor markets- how did they let this happen when they used to be number one by a large margin?
Before that book came out and after I had graduated from college and did a brief stint at Radio Shack, I worked at a market research company. They specialized in competitive intelligence in the energy industry. We stored our primary research in you guessed it, a database system. This was my first exposure to using SQL on a green screen. The datacenter contained a system by Sequent Computer Systems.
Only the Plugged-in Survive
Today we don’t use paper-based media monitoring services anymore- everything has gone digital. But it is still “catch as catch can” even using things like Google Alerts. Keeping up by using social media? Good luck with that, even with aggregation tools. You could miss something if you are not looking at a computer screen. FOMO is real for the paranoid!
Let’s see; I am on and try to keep up with: LinkedIn, Discord, Slack, Reddit, Facebook, Twitter, Instagram. I tend to let serendipity and dumb luck drive some of my viewing habits. I read books (!), and go to several Meetups (100% over Zoom at the moment, ugh). Same for on-line conferences. I listen to podcasts. I subscribe to too many e-mail newsletters. I watch streaming shows. I have conversations with people. And yet I could still miss something important!
My lingua franca today is Python 3. I’m using it more and more in the things I’m interested in both personally and professionally.
I’m currently going through a book (second edition) and Udemy course called Automate the Boring Stuff with Python Programming. NOTE!!! The author has generously created a Creative Commons version (free) available on the book’s website. So why mention the book and course? Because I am learning about web scraping for personal use- please don’t break the law.
RAPIDS is Rapidly Changing
In my last post I talked about how I’m taking a new, technical, immersive, deep dive into RAPIDS. Since I wrote that, I have acquired (again through dumb luck), an NVIDIA RTX 3090 for my gaming, VR, and data science interests. This card requires three (!) power connectors. It is a beast!
Alas, even as I’m taking copious screenshots and notes using OneNote, they are releasing new features with every release- roughly every six weeks, which at times feels like that is faster than I can learn about them. And they are re-naming things too. So even as I’m documenting and coding my personal corpus on RAPIDS, I’m performing find and replace on content. On newly learned info! I also have to change some of my mnemonics to reflect new changes too which is frustrating to me.
Even if I get the chance to write a book about it, like Andy, imagine the overwhelming feeling of writing something that parts could be obsolete by the time it is published! Ah, the joys of being a technical writer 🙂
Learn and try to stay plugged-in. Talk to people. Ask questions on forums.
People, there is life outside of an electronic screen. Just do the best you can and don’t sweat it. The chances that I’m going to be blindsided by some new hotness is slim to none. Even if I’m not the first to know, I’m sure that if its important, somebody in my social circles will hear about it.
During Lent 2021, I stepped away from writing and social media. Winter is over and I’m looking forward to a lot of writing in the months ahead.
This month’s T-SQL topic by Steve Jones is on using Jupyter Notebooks. I first saw their use for the first time at the PASS conference in 2019 (remember PASS?). What I thought was cool was the ability to both run code and save results too. Even have text, images, etc- just like a paper notebook.
I’ve been a SQL Server DBA for most of my data career. Some of you have wondered what the future looks like for DBA(s) and something I’ve wanted to have a reason to get into is data science. I don’t remember exactly how I first heard about RAPIDS from NVIDIA, it was probably something I stumbled across from following them on Twitter.
NOTE!!! Don’t miss the free conference starting on 12Apr21 all week, they will have a lot of new announcements and plenty of free training resources too: GTC.
What Is RAPIDS?
From their website, “The RAPIDS suite of open source software libraries and APIs gives you the ability to execute end-to-end data science and analytics pipelines entirely on GPUs. Licensed under Apache 2.0, RAPIDS is incubated by NVIDIA® based on extensive hardware and data science experience. RAPIDS utilizes NVIDIA CUDA® primitives for low-level compute optimization, and exposes GPU parallelism and high-bandwidth memory speed through user-friendly Python interfaces.”
The teams at NVIDIA have been working really hard to try to maintain a familiar Python syntax for existing libraries but have them run on the GPU(s). Here is their release roadmap; version 0.18 is what I’m using.
GPU stands for Graphical Processing Unit. Anybody with an NVIDIA graphics card (Pascal or higher) can run RAPIDS. Right now, it only runs on Linux; I failed to get RAPIDS to use Windows Subsystem on Linux (WSL) as I only have a Maxwell based GPU on my gaming rig. I’m hopeful that once I get a new video card, I’ll re-visit running RAPIDS on WSL. If you are wondering, I tried to follow the steps both here and here.
Here is a video talking about how Wal-Mart is using RAPIDS.
Dual Boot Using An External SSD Drive
It just so happens I received a new laptop for work and it has a Pascal GPU! But alas, this is a work system so I can’t install Windows Insider Preview versions. I also didn’t want to risk fiddling with partitioning the internal drives either.
Low and behold! I stumbling across this video trying to research installing Ubuntu on an external drive. Since I had all of the parts, I didn’t have to buy anything. NOTE!!! The video is over a year old and some of the steps have changed. Just be sure to stick with Ubuntu 18.04; don’t upgrade to 20.04.
I have been running this for a few weeks now without any problems. My work laptop is unaffected and I can learn RAPIDS using this configuration albeit with a limited amount of GPU memory.
Installing SQL Server on Linux
Sticking with the instructions for Ubuntu 18.04, I installed SQL Server on Linux. I also got Azure Data Studio for Linux installed too. Downloaded and restored the AdventureWorks databases. I then ran through several steps to get the Python drivers installed. This site was very helpful (remember to stick to the 18.04 instructions) and I was able to get things running from within a Jupyter notebook. Finally!
Running Jupyter Notebooks Using Docker and RAPIDS Container
Click on the link [http://localhost:8888] in a browser like Firefox and the notebook will open.
Since I’m focused on leveraging existing data skills to learn GPU things, I was interested in things that had a SQL syntax. Note there are several notebooks covering many of the tools within RAPIDS which can be found in the container.
(caveat: the following examples are from https://app.blazingsql.com which will be shutting down and will be re-branded as something else? Time will tell.)
What follows are several screenshots from me copying code from their site and running it locally on my machine. These examples use NY taxi data (46MB).
What is so neat and cool to me is to be able to run queries and plot data without a whole lot of headache or software installation.
SQL Server -> Pandas -> cuDF
The component known as BlazingSQL is an in-memory data analytics tool which uses the CUDA dataframe (cuDF)- it doesn’t persist data. By using SQL Server, one can use all of the tools many of us are familiar with. The following screenshots show how I connect to SQL Server on Linux using Python inside of a notebook and then load a GPU dataframe, then show some metrics about it.
These are the results from running gdf.info(verbose=True) from above:
I know this was a whirlwind tour. Jupyter notebooks has made it easier to query data, see results, and do Pythonic stuff. RAPIDS is getting a lot of attention as it can do things much faster on the GPU than on the CPU like SQL Server. I hope to write more about RAPIDS and its use in data science.
The first post of 2021 for T-SQL Tuesday is being hosted by James McGillivray and his updated post on the subject of taking a break can be found here. Thanks James!
Sadly one of the members of the #SQLFamily has passed away due to complications from COVID-19, Gareth Swanepoel, and the organization once known as PASS will be no more on 15Jan21.
I maintain #SQLMemorial and you can watch the latest tribute video to the fallen here.
Week 1: A Fresh Start
I’ve written Part 1 and Part 2 about getting into MBSR so this is more of a re-start than a Part 3 post. When the pandemic really kicked into high gear mid-March 2020, I just didn’t stick with the commitment of 40-45 minutes each day for eight weeks. A few weeks into it and I spent my time getting outside to go for walks and taking power naps instead.
2021 is a new year with new goals so I’m stopping to breathe again. Secret? Put it on your calendar throughout the day and make time. All of the PDF(s) and audio files for the MBSR course I’m going through can be found here.
It is a fascinating book and I’m really enjoying it. In one of the chapters, he lays out a exploration into the treatment of augmenting an existing therapy using VR for people with schizophrenia which grabbed my attention.
Back in March 2019, I wrote a little about digital avatars and the incredible progress in creating live-like avatars but using something other than a human. T-SQL Tuesday #112 “A New Cookie Jar”.
Now this technology is becoming more accessible. Take a look at the beta version of Audio2Face video created as part of NVIDIA’s Omniverse suite of software. Please note that it is only using an audio file- no programming by the end user was required.
Back to VRx. Imagine someone being bullied by their inner demon, a satanic figure with two ram-like horns, blood-red skin, massive bat wings, and talking to you a short distance from your face. “You are no good. You are a bad father, You are a bad husband. You are worthless!” Chiding, insulting, distracting, incessantly.
Disturbing visual and audio to say the least. But that is what a psychiatrist has been able to do- create an avatar as close to his patient’s hallucination but using the psychiatrist’s voice. And over the course of treatments, the audio becomes, “You’re not as bad as I thought. I underestimated you.”
So, let’s look at the flip side for positive mental health applications. Imagine someone or something saying positive, uplifting and affirming quotes and sayings. How would that make you feel? Better than trying to talk to oneself in a mirror I suppose.
While positive psychology entails more than just technologies, it could be interesting times ahead for positive avatars helping and encouraging people.
One More Thing
I know several folks who are in the #SQLFamily and are into video games, myself included. Epic Games releases a FREE game every week from their on-line store.
On 14Jan21 for all of you Star Wars fans, Star Wars: Battlefront 2: Celebration Edition will be released and free for a week. Once you claim it, it is yours. I have over 120 games I have downloaded from the store over the past two years- all for free.
I have been into Unreal Engine as a hobby for a while, and I’m not a game developer by trade or by education. When learn.unrealengine.com came out, I was excited to take courses.
On November 18, 2020, they announced the 2020 Fall Unreal Online Learning Challenge and I decided to jump in. Truth be told, I had already taken the Build a Detective Office Game Environment course but I took it again anyway as a refresher.
I hope this Lessons Learned post will inspire people to jump into Unreal Engine now and in the future as it is a fantastic game engine but thanks to this FREE learning portal, it is not as intimidating to learn as it once was. As the saying goes, if I can do it, anyone can do it!
I have been working with databases as a full-time job for over 20 years and currently work for a non-profit. I help run the Denver/Boulder Unreal Engine Group and thought this would be something fun to do- to lead by example and dive right in. Someday I really want to get back to meeting in person (I’m in Zoom calls all day long). I use UE4 for a lot of personal projects and am looking to do even more with it in 2021. Stay tuned!
In order to take all five courses in the time allotted, I really needed to focus and set aside other tasks so I could concentrate and complete on-time. My methods are as follows; they may or may not work for you but they work well for me.
I use OneNote for screenshots of slides presented in addition to stopping the videos and taking notes.
The authors of these courses are very knowledgeable and I don’t want to miss anything.
Second, and this is extremely time-consuming, I watch ALL of the videos, straight through, and only stopping and taking notes if it rings faint bells and I need to research something further. Meaning, I just want to “see” the whole thing in a short period of time to get a feel for what I’m getting myself into.
Third, I re-watch them, going slow and taking notes as I go along and working through all of the examples while I have UE4 open and following step by step. If one were looking over my shoulder, one would see me using two screens, OneNote, UE4, SnippingTool on one, and the course itself on the other. I’m constantly cycling through windows using Alt+tab as I’m going through the material.
In my experience so far, I average about 2-3 hours (sometimes longer if I’m not getting or immediately understanding everything) for EVERY hour of content. So a three hour course might take me all day using this method.
One more thing which I find extremely important- REVIEW!!! If one is taking the time to laboriously take so many notes, take time to review them immediately afterwards since writing them, and glance at them before starting the next module. Try to recall (from memory) what the content was about and your own notes on them. This is hard and yes, even boring at times- new content to learn is calling!!! However if one really wants to understand the material, slow down and take time to review. It is an investment, and not a waste of time.
I do try to follow the authors on Twitter if they are on there (I’m @toddkleinhans by the way) and add any and all links to books, courses, other resources they recommend. Note that some of the courses they reference may or may not have already been published.
Other Thoughts and Observations
4.26 is the latest version as of this blog post on 13Dec20. It is the nature of software development to always be upgrading. I had to install 4.23 to complete some of these and it felt quaint 🙂 Always use the version the authors’ are using as this will help to minimize the risk of the projects files not working correctly.
I wish the courses had transcripts with them- I spent A LOT of time stopping and starting the videos over and over again just to catch and type what the author(s) were saying.
Learning about the organization and naming system for things was valuable too.
I LOVED the deep-dive into The Village for some of the courses. An exploration into the look, feel, mechanics, Blueprints and C++ code behind the game. Being able to “wrap my brain” around it was important and highly instructive to me.
Even though I have successfully completed the Challenge, I can’t wait to take other courses in 2021 too. I not only want to see so many more badges on my Dashboard, but more importantly, I want to be able to apply what I have learned. And re-visit the courses when necessary- don’t be embarrassed if you forget something or need a re-fresher!
After completing this Challenge, I now have the technical insights and expertise to re-visit and improve a personal project of mine.
Some of the technical aspects can be found here. Note that I now know how NOT to do things in the Level Blueprints, I’ll be changing and improving it, based on the audio courses I just took. Heh, I did have that overwhelming feeling of, “Oh… I didn’t know that… I need to change that when I get a chance!!!”
My latest YouTube version (using OBS to screen record audio and video) here.
Keep taking courses, notes, and adding to one’s own toolbox. This Challenge was intense for me. It really gave me a good proverbial kick in the pants to step up and dive in while yes, at times, being COMPLETELY outside of my comfort zone but slogging through, re-watching things over and over again until I “got” it.
The Challenge opened my eyes to several new things and many ways to improve existing projects I am working on. Thanks for reading!
For the T-SQL Tuesday topic this month, Lisa Bohm asks, “This month, I’d like those of you who have presented, or written a presentation, to share something technical THAT DID NOT RELATE to the topic of the presentation, that you’ve learned in writing or giving the presentation.”
I had an idea of how to do a better technical presentation years ago using a video game engine instead of PowerPoint. Why? I could “walk around” inside of a game. It had so many parallels to memory palaces. But it was hard for me and it just seemed like I was trying to wield a hammer in a blind search for nails.
From walking around execution plans, to various joins and seeing visual intersections of spheres of data, I just wanted to go wild with a sight and sound exploration of technical topics using intense video game capabilities.
“As a doctor, you of all people should be aware of the dangers of reopening old wounds,” Admiral Kirk in The Wrath of Khan.
One of the fundamental cruxes all artists bear is that their vision far exceeds their abilities to realize what they see in their mind’s eye.
Project #SQLImaginarium is one of them for me.
I had a grandiose plan and strategy, I lined up the skills, education, tools, and experience I would need to pull it off and…
Failure. Failure after failure. No one was paying me to do this, it was all spare-time efforts and frustration to learn and use the tools.
I flat-out dropped it at times. Then picked it back up and worked on it only to get upset and wash my hands of it. Rinse and repeat.
One positive that did come out of all of this was the idea and the creation of #SQLMemorial – one can see the latest version here.
If there ever is a fundamental flaw to me, is that my dreams, once set in motion, never die. They just keep coming back.
It has has been a long road for me. I’m not a game designer by trade or by degree or by formal training. I am completely self-taught.
Then VR showed up and I thought, “WOW!!!” I know a game engine now, just do a VR version of your vision!!!”
As time has marched on, my skills in these areas has dramatically improved over the years. Are my ideas too little, too late? Or was I simply ahead of my time?
I accepted a new job in the middle of this pandemic this year and I love it! I am also slowly coming out of my hiatus from several back-burner projects.
Personally I have accepted this new operational tempo of working from home under pandemic duress and am dealing with it. Some days are better than others, some days not so much.
2021 is going to see a lot of content coming from me and not all of it will be data related. So if a #tsql2sday topic doesn’t strike my fancy then I might not write about it. I’m into a lot of different things at this point of my life right now and not all of it deals with data. Data and the data community as much as I love it is NOT my life. I used to think that it was- data is me, it is my career, it is who I am, etc. But that is so short-sighted. Life is too short to define oneself in those terms. 2020 has seen the death of friends and family and acquaintances and I’m not going to choose to waste precious resources and time.
On a family trip long ago, I once visited Walden Pond with my Grandfather. Loved the book of the same by Henry David Thoreau and longed for simplicity in my life. For me 2021 is going to be a year of, “Simplicity, simplicity, simplicity!
Within the last 72 hours as of this post (afternoon of 08Dec20), there have been three board members step down (read resigned) from the organization known as PASS.
This is heartbreaking to myself and others as PASS has helped not only my data career but the careers and jobs of many others. A membership of over ~300,000 is nothing to sneeze at- that is a significant number of professionals from around the world. There has been much speculation as to what is going to happen to it in the days ahead and I understand they have to follow appropriate legal and business protocols. I hope a white knight is going to save the day. If not and PASS dissolves or goes defunct or ceases to exist, a phoenix will rise from its ashes and people will connect, learn and share in other ways or in other organizations.
NOTE!!! I am not under any NDA, I’m not in the inner circle, I do not have any insider knowledge. Everything here are my own opinions, thoughts, and speculations.
I have been active in the local Denver SQL Server User Group for more than ten years. I’ve seen people and technologies come and go in that time, things are super hot and then deprecated and the like. Times change and people change with the times.
PASS used to stand for Professional Association of SQL Server then it just became a brand name with no real meaning behind the acronym.
A while back I tossed around the idea of a re-branding of sorts:
The Professional Association of SQL Solutions. Still PASS from a brand name, URL, trademark, etc. but a focus on data platforms which run queries. Required membership dues like other professional organizations. Beholden to no one other than the members and any future sponsorships are treated as grants, aka free money- no strings attached. When in-person events start back up, then look at tiered offerings. Consistent user group/event platforms like Bevy and Zoom for speakers (paid/compensated for their presentations too).
This would mean becoming inclusive of ALL data platforms, not just the ones Microsoft builds or supports. Does this mean including that OTHER platform, SQL Servers’ arch-enemy and the endless butt of many jokes over the years???
Yes. It would include Oracle and things Oracle has taken over, like MySQL.
“Are you a data professional who uses any type of query in your full-time job? We would like you to join us.”
With the rise of the cloud, a pay-per-query model is now here and there will always be a market for people who can write and tune queries. Until we are replaced by robots- wasn’t that supposed to happen any day now? 🙂
To paraphrase a quote from one of my presentations, The Life Cycle of a Query in VR (in my best, late, great, Carl Sagan voice), “Billions and billions of queries are run everyday. Knowing the cycle of how EACH one runs and what it touches to manipulate data is to better understand the data universe around us.”
For those of you who do not know, I maintain #SQLMemorial which can be viewed here. Never in a million years would I have ever thought I would be putting the name of an organization that has been a big part of my data career on it. I hope it doesn’t come to that fate. Time will tell.
In the course of researching food security years ago, I have been interested in using tech to address food, water, clothing, and shelter in a manner that is beneficial to the long-term for a group. But I quickly learned that there is more to truly helping people than just their physical needs. My mind takes me back to The Bible and the story of Joseph and the Famine.
I have always wondered, how did they store that much food? What did the storage look like to prevent spoilage, rot, rodents, etc.? Topical questions, I know.
It was in that context I first stumbled across a video called Harvest of Shame. I watch it every year and think about what has changed and what has not, now in the last 60 years. It first aired just after Thanksgiving in 1960. Note it is a period piece meaning it was a documentary at that time in 1960- it opens with a cigarette sponsor, smoking is prevalent, things one will see and hear cause me to personally be uncomfortable.
The following is pure speculation by an amateur futurist 🙂 Robots and drones have been on my mind for quite some time and they are still ridiculously expensive to build, program and maintain but costs are coming down and capabilities are increasing.
Using the above, imagine commercial, industrial robots being picked and placed in crop fields using heavy-lift drones. My vision for what these might look like could be right out of science fiction and probably very creepy looking. Like giant spider creepy looking.
On the surface, using telerobotics controlled by operators located anywhere in the world sounds like expensive overkill to replace seasonal migrant farm workers. But this is more than just replacing humans with robots.
The Dark Side
I’ll come right out and say it- I have concerns about the potential for high-tech being used to exploit labor costs. Skilled and unskilled labor markets are going to be potentially affected. Imagine if you will super low-cost labor with access to the above technologies. Fruit and vegetables in America being harvested by operators on the other side of the globe in a developing country. Foreign workers who never have to travel to a host country. Incarcerated, Children, Elderly (ICE) labor at below current piecemeal rates. Widgets getting assembled by a multi-national labor force switching between operators from beginning to end depending on the cost of vetted spot-labor.
The Bright Side
Robots are perfect for the 3Ds: dirty, dangerous and demeaning. The intersection of the technologies above will create new jobs for remote operators, remote console manufacturing, industrial robots, programming, drones, service and maintenance of it all- I think it will be neat to watch how all of this will transpire.
As I count my blessings this Thanksgiving, I remember where food comes from- many people working hard under harsh conditions oftentimes for back-breaking hours on end. Technologies can be used to allieviate some of that suffering but how to do that without also introducing new levels of suffering and problems.
Call me old school. Back in the day, if one was caught sleeping on the job, that was a fireable offense and one could lose their job. The concept of even taking a quick nap was verboten.
For years I thought well, what if I just go out to my car and catch a few winks there? It can work and I have done that in the past but it is not comfortable plus I’m kind of self-conscious about it- I don’t want a passerby to think I’ve suffered some kind of accident and then notify the authorities and cause an issue. Even to avoid co-workers wondering about me I have been known to drive someplace just so I could nap out of sight…
Sleeping on the Job – New and Improved!
A skill or natural ability I have is to be able to fall asleep quickly. My wife hates it as it takes a while for her to wind down in the evenings. Me? I can lay down and be sleeping in roughly 10 minutes. This has caused her to wake me back up if we were in the middle of a conversation and she wanted to finish talking about something.
I have been mostly working from home for the last two+ years. When the pandemic hit, many people were forced to work from home (WFH). For me my day to day really did not change. However I was affected by the pandemic too as we all were and it disrupted my life.
While I am not an expert on the art of the Power Nap, I am aware and highly endorse all of its benefits. I try to stick to a tight schedule but alas in today’s crazy meeting driven WFH lifestyle I cannot always take a power nap when I want to. A siesta is always the easiest way for me to take a power nap right after lunch whenever that occurs.
I’ll set an alarm on my smartphone (usually 45 minutes from when I start), grab a warm blanket, and find a comfortable surface (sofa or bed but usually not under the covers), and focus on falling asleep. I know for many of us, working in IT doing something like programming it can be hard to un-plug. We lose our head of steam and it can take a while to get back up to speed and this can be a source of keeping one awake when one wants to fall asleep!
From the start of the power nap time (wind-down, actual sleep, wake up) I can maybe squeeze in half and hour of sleep. Do I take more than one power nap a day? Sometimes, especially between meetings. This is the challenge- how does one temporarily silence their smartphone and other distractions to sleep while still maintaining the availability to be reached in the case of an emergency? Block the time on your calendar as personal time- YES!!! With our WFH schedules and lifestyles this shouldn’t be a problem- even talk to your boss about it. As long as one is putting in the work hours, I think most places would be accommodating. Or don’t put it on your schedule and try to nap between “interruptions” haha.
A Memory From My Yoot
I use that word a lot. At the risk of mansplaining a yoot, here it is. When I was in high school, I knew this one guy who was a crazy smart programmer who carried a briefcase to school. Heh, remember briefcases? Odd thing was, we never saw him open it. What was in it we wondered? Programming secrets? Stealing things from the school? Why does a high school kid need a briefcase, what is he hiding???
Then one day, I was passing by the library during lunch and I saw it! He was in the back of the library with his briefcase open.
I couldn’t believe it, the mystery was solved!
The briefcase contained a giant pillow and his head was down, taking a power nap.
To quote the late great Paul Harvey once again, “…and now you know, the rest of the story.”
This month’s topic is being hosted by @sql_r – thanks Rob!
“For this month’s T-SQL Tuesday, I’d like you to write about your favorite analogies that help explain database concepts to people who aren’t database experts. I like the spirit of Reddit’s Explain Like I’m Five (ELI5) subreddit, where the explanations are meant for someone who has no previous assumptions about the topic.”
At a dinner party long ago, I was asked what I did for a living and was met with some odd looks. Truth be told, numbers are not my thing and I barely passed my accounting and finance classes in college.
Trip Down Memory Lane
One of my favorite documentaries about computer history is called Accidental Empires by Robert X. Cringley (TV version was called Triumph of the Nerds). There was a scene where before the electronic spreadsheet was invented and coded into software (VisiCalc) a professor was standing in front of a chalkboard. The kind that created nasty chalk dust and make a distinct sound when writing with it. This professor was writing a pattern of grids on the board – it was a chalk version of a spreadsheet. When he needed to re-calculate a set of cells, he make the calculation on a TI Business Analyst hand calculator, erased the previous results, then wrote in the new calculations.
Dan Brinklin got the idea that this could be done on the computer via software and the professor started shaking with anticipation, “You don’t understand, this is what I have to do all day!!!” Visions of helping accountants and bookkeepers and business people really spurred him on.
Back To The Party
So I struck up a conversation with someone who was an accountant (also called a bean counter, outside of financial circles). They asked what I did for a living. I said I worked with databases and tried to expand on that…
“A database is set of two computer files, a data file and a log file. Got to be sure they stay healthy!”
More blanks stares. I was going to try something different. Hold my beer.
“A data file is like a chart of accounts. It has everything you need to run the business. The log file is like the general ledger– transactions get posted from here into the chart of accounts.

As a database administrator, keeping the log file of any database backed up and running smooth is very important to me.”

Try to put things into terms your audience can understand, especially those outside of your technical expertise.
