Should you Fire a Coworker for Making an Honest Mistake?

A while back my hairdresser accidentally cut my ear. It was just a small cut and I hardly felt it but since cuts in ears have a tendency to bleed a lot my hairdresser felt really bad and almost starting crying.

After having driven home with one hand on the steering wheel and the other hand holding a towel to my ear (it’s hard to drive a stick that way), why wife went into conniptions and while she tried stopping the bleeding she demanded that I find a new hairdresser.

“Why would I do that?”, I asked.

“Well, obviously this one is highly incompetent. And she even made you pay 100 DKK for this mess”.

I said: “I am not going to find a new hairdresser. I just invested 100 DKK to be absolutely sure that this hairdresser will never cut my ear again.”

So far I have been right. The nice little scar on my ear reminds my hairdresser to be extra careful and thorough :-).

Once in a while you read about developers being fired for making honest although massive bugs. The question is: Is it the right thing to fire people?

Personally, I think it is the wrong thing to do. Making an honest mistake is not enough to get you fired.

But it all depends on how you handle that mistake. If the person who made the mistake steps up to the plate, takes responsibility and does everything he or she can to fix it and learn from it, then you as a company will not get a better co-worker by firing and hiring somebody else. The new guy might even make the same mistake. It’s also very likely that the mistake happened because the processes in your company are not good enough.

What do you think is the right thing to do?

Working Effectively with Windows as a (non-)Developer

There are lots of great articles on how to know your tools to be a better programmer. I thought I’d chip in give and give 10 tricks on how to be a good Windows user and hence also a better developer. These tricks are very simple and have been part of Windows for a while (some even before Windows 10) and yet they are unknown to many Windows users.

There has always been an ongoing war on whether macOS or Windows is the better. I am a user of both and I love and hate both of them (although I am more effective on Windows). I hope the following tricks can be of help to Mac users who sometimes need to use Windows, and also of help to existing Windows users who perhaps can learn a new trick or two.

I would be happy to hear about what tricks you use to make life easier so please join in on the comments.

These tricks all apply to Windows 10.

1. Show file extensions in Explorer

For some reason the default setting in Windows is to hide all known file extensions.

There should be a law against that.

So, the first and most important trick is to get Windows to show all known file extensions in Windows File Explorer.

For example, I had a client that stubbornly claimed that double-clicking the MyApp.exe file would only show some gibberish in Notepad. After a while it occurred to me that the standard .NET configuration file MyApp.exe.config file showed as MyApp.exe on the client’s machine because the file extension .exe was hidden.

So, the first thing you do on a new Windows box is to open Explorer, click Options -> Change folder and search options. Go to the View tab and clear the check box for “Hide extensions for known folder options”.

2. Use the Run command

The second most important trick is the “Run” command in Windows. Mac has its very useful Spotlight Search, and Windows has its equally useful Search feature in the Start menu, but I find the Run command much more useful.

The Run command allows you to run one-line command line instructions. You get to the Run command by typing Windows+R on the keyboard. That will open up a small dialog to the lower left where you can type any command.

The Run command gives you a very fast way to start apps or open web pages. The following are a few common examples:

  • calc (starts Calculator)
  • notepad (starts Notepad)
  • excel (starts Excel)
  • winword (starts Word)
  • mstsc (starts remote desktop terminal)
  • inetmgr (starts the IIS Manager)
  • cmd /f:on (starts a command prompt with tab completion)
  • (opens the default browser and goes to
  • (same as above)
  • %programfiles% (opens Explorer and goes to the program files folder, usually C:\Program Files)
  • control panel (opens the Control Panel)
  • services.msc (opens the services panel)

3. Use Windows Search

I already mentioned it above, and I will mention it again. Few people realize that Windows has built-in search similar to Mac’s Spotlight search.

Just press the Windows button on the keyboard to open the start menu and start typing immediately. This will search for apps and files and the search results show immediately on the start menu. It evens searches tags in images and content in pdf files.

I actually never understood the hatred for Windows 8 and 8.1 and the large start menu. To me it was just a big friendly searchable start screen. But I guess I was the only person in the world that liked it.

Unfortunately, Windows Search does not search the internet.

4. Use the Power menu

The power menu is shown when you press Windows+X on the keyboard. The power menu gives you immediate access to the most important stuff such as settings, event viewer, network connections, and the command prompt.

Speaking of the command prompt, if you prefer to use PowerShell, you can replace the command prompt with PowerShell on the power menu. Right-click your taskbar and choose taskbar settings. Then turn on the setting “Replace Command Prompt with Windows PowerShell in the menu when I right-click the start button or press Windows-key+X” (now that’s a long sentence).

5. Easily start new instances of an app

As you know you can start an app by clicking its icon on the taskbar.

Now, if you want to start more instances of the same app, you hold left-Shift and click the icon.

And if you want to start an app as administrator, you hold left-Ctrl and left-Shift and click the icon.

You should pin command prompt and PowerShell to the taskbar so that you can start and administrator prompt just by left-ctrl + left-shift + clicking it.

You can also start an app that has been pinned to the taskbar simply by holding the Windows key and pressing the number for the app. So, for example, Edge is the third app om my taskbar, so I can start it simply by pressing Windows+3 on my keyboard.

(I apologize for my hopeless, childish handwriting)

6. Use the Snipping Tool

This tool is very helpful for capturing screen shots and I use it all the time, for example for writing blogs. Just search for “Snipping” in your start menu to use it.

You may find difficulties in snipping a screen shot of menus and such but of course I have a trick for that:

  1. Start the Snipping Tool and click New.
  2. Press the Esc button on your keyboard.
  3. Open whatever menu you wish to capture.
  4. Press Ctrl+Print Screen on your keyboard.
  5. Now you can draw a rectangle of with the Snipping Tool to capture the menu.

7. Copy the path of a file

Left-shift and right-click a file to reveal a number of extra items on the context menu. One of them is “Copy as path” which will copy the file’s full path to your clipboard. Neat.

8. Use shortcuts

Some common shortcuts:

  • Windows+E: Start File Explorer
  • Windows+D: Show the desktop
  • Windows+I: Open settings
  • Windows+Ctrl+D: Create new virtual desktop
  • Windows+Ctrl+right arrow: Go to next virtual desktop
  • Windows+Ctrl+left arrow: Go to previous virtual desktop
  • Windows+Ctrl+F4: Close current virtual desktop
  • Windows+arrow up: Maximize window
  • Windows+arrow down: Minimize window
  • Windows+arrow left or arrow right: Snap window to the left or right border

By the way, if you grab a window by the title bar and shake it with the mouse, all other windows on the desktop will be minimized.

9. Keep your Windows desktop clean

With Windows search and the run command, who needs icons on the desktop?

Add shortcuts to the taskbar for the apps that you use the most for easy access and leave the desktop clean and uncluttered.

10. Easily create connection strings

The last trick for now is for developers. I find it incredibly useful and I have not met a single person who knows about it since I learned it many years ago. So I decided to include it here as a small bonus for those who made it this far.

I can never remember the syntax or the property names for connection strings when connecting to a database from code on Windows which is why this trick has helped me for years. A long time ago at a conference (in Boston I believe) I saw the presenter creating a file on his desktop with the extension .udl. Then he double-clicked the file which opened a small dialog where he entered SQL Server instance name and selected authentication and database name.

After dismissing the dialog he opened Notepad (by pressing Windows+R and entering “notepad”) and he then dragged the .udl file to Notepad, revealing a beautiful connection string. How about that!

By the way, the .udl trick won’t work unless you have followed the very first trick on this list: “Show file extensions in Explorer”.

I hope you find above useful 😀

Autonomous F16 Wingman

The USAF is testing autonomous wingmen fighter jets.  While I am a sucker for all things fighter jet, especially the F16 Falcon, this is both very fascinating and very unsettling.
