  • Are We Suckers?

    I written about learning to say no. I’ve noted that we must find a balance in life with work. I try to encourage you to work hard, get better at your job, and bring value to your employer. I certainly know there are plenty of employees that coast along in their jobs, doing often less than what I would consider the minimum. I’m hoping that more and more of you are trying to do better.

    However, when I read pieces like this one where a CEO wonders why employees don’t work harder, I get frustrated by managers that don’t seem to understand that work is merely work for many of us. We enjoy it, we want to do well, but it’s just a part of our lives. We have other things in life that we love and are more important than work.

    However I also know there are plenty of you that go the extra mile. You routinely work outside the normal business hours to solve problems, or just deploy changes to system. I’ve been there, and I’ve wondered why I’d bother working from 11pm Sat – 4am Sun for “routine maintenance” if I wasn’t being paid an hourly wage. This week, what do you think about this?

    Are we suckers for working extra hours?

    I know plenty of people enjoy the work, and they rise to the challenge of responding in a crisis. One of the hardest things I had to manage was getting people to go home and rest when faced with an extended crisis. It seems I had no shortage of employees that wanted to work 30, 40 or more hours in a row, and I’d argue to send them home to rest because I’d need them to work tomorrow night.

    I think that we should make an honest effort to give our employers value. We should do the work assigned, perhaps do it better today than yesterday, and be flexible when more work is needed. I also think employers should do the same thing. Extra hours at work should be extra time off. Compensation should relate to to performance, but not hours worked. Sacrifice by employees should be met with sacrifice by employers.

    In other words, just like my balance between work and life, there should be a balance between employers and employees with each side respecting the other.

  • The Lost Laptop Crisis

    I wrote about the dangers of travel awhile back, where I had concerns about information when crossing the borders of a country. However that’s a case that most of us encounter rarely. However many of us do move information around on a regular basis with our devices, carrying them wherever we go. Each time we change locations, there’s a chance we’ll forget a device, or that one might be stolen from us.

    There is a limited amount of information in our phones and tablets, but in many laptops, we can carry more information, and often do. No shortage of us keep database backups or imports/exports of data for development purposes. Our clients certainly have reports or data in Excel, but often that’s a limited amount of data compared to what some of us might keep on our machines. In thinking about this, I wanted to ask this question:

    What would you do if you lost your laptop?

    I’m talking about the main laptop that you use for work. What’s on it? What’s important? How would you react? Have you even thought about it?

    I have, and I’ve had laptops die, though never stolen. However I have taken some precautions. When I get a new laptop, the first thing I do is enable the whole disk encryption in Windows or OSX. I keep backups of the recovery codes at home and I make sure I’ve taken advantage of strong passwords and other encryption for information I carry. I don’t have passwords saved for any VPN or other secure connections to banks or work.

    It’s not a perfect solution, but it’s a start. Let me know today if you take other precautions.

  • Positive or Negative

    While watching a presentation recently on a SQL Server topic, I was surprised by a design technique that the speaker used. I hadn’t ever thought of the issue, but it caught my eye and made me rethink the way I look at design, and even data.

    In this case, the speaker was building a table and looking to make a row active or inactive. This person chose to use a column name of “inactive,” which surprised me. I’ve always used an “active” column if I am trying to mark a row in a binary fashion.

    That got me thinking. I wonder if there is some impact to designing entities either way, but I wanted to ask this question:

    Are you positive or negative. Would you use an active flag or an inactive flag?

    This could be extended to any other type of choice, but do you look to flag an action as happening, or not happening. As readable or not readable? As usable or ignored? I’m not sure it matters, but I’d certainly be curious if anyone has any reason why you might choose one or the other. Is there some meaning conveyed? Let us know this week.

  • ER Modeling

    I saw someone recently note that an Entity-Relationship model is important for your database development project. That UML is important, and the model should be actively maintained. I agree.

    However, I’ve usually not seen this done. Typically when I’ve seen an ER diagram in a shop, it resides on a wall, printed out on multiple sheets of paper. Often there are as many handwritten additions on the pages as there are marks from a printer. The diagram is also usually out of date, even allowing for handwritten notes.

    Maintaining a diagram is hard. Deciding to actually spend time working on one instead of just talking about a few entities and building them, may be harder. This week, I wanted to ask you if you’re up to the challenge in your organization.

    How many of you maintain an ER model for your database?

    Do you have an ER diagram you’ve built? Whether it’s in ErWin, Visio, or Paint. Is there a diagram that’s actively maintained and that everyone can use for designing changes to the database(s) in use? Do people actually consult this and use it in design meetings? Let us know this week.
