My Visio Presentation from the PowerShell Summit 2014  

My session wasn't recording last week, so I rerecorded the video and enhanced the content for viewing. Video and link to materials below

Exporting the Contents of a Git Repository with PowerShell  

Recently I needed to export all the source code from a Git repository into a Windows fileshare (and once there other operations would be performed.

Below is the PowerShell script I used to accomplish this for a repository on GitHub.

$GITEXE="C:\Program Files (x86)\Git\bin\git.exe"

# Clean out destination folder
if (Test-Path $DESTDIR)
    Remove-Item -Recurse -Force $DESTDIR

# Clone from repo to folder
&$GITEXE clone --depth 1 $REPO $DESTDIR

# Remove non-source code files from the destination folder
Remove-Item -Recurse -Force ( join-path $DESTDIR ".git")

As a follow-up, if you do this you may need to ZIP up the results. Check out my previous post explaining how to create ZIPs easily with PowerShell.




Comic Neue  

My lst few blog posts have been about typography, so I'll continue the trend by highlighting a recent discovery. Inspired by Comic Sans, we now have Comos Neue ( by Craig Rozynski.

Available in several weights and styles, it may be exactly what you are looking for to maintain the friendliness of Comic Sans and still be very professional. It's also public domain and free.





Look up when you play an FPS. You might have missed some cool ceilings.  

From the original thread on reddit, Apparently I don't look up enough when I play Deus Ex: Human Revolution because I missed some really unique ceilings.

The full list is here: Below are three that I particularly liked. Click on the images to see a larger version.

(Speaking of the topic of looking up, I did much more of that in Dishonored –  which plays just like DE:HR –  because Dishonored's “blink” ability will naturally start having you look for destinations to perch on well above your current position.)









Should you get a 4K or Ultra HD LCD Monitor for your PC?  

One-line Summary

If you have several thousand dollars you urgently need to get rid of, then yes. Otherwise wait (and it may not be a long wait).


What's got everyone talking

It started –  more or less –  with Dell's February announcement of two new Ultra HD Monitors. A quick summary:

And Dell isn't alone:


The Tempation

We simply haven't seen 4K reoslution in this price range. Compare them to the 30” HP ZR30w which offers 2560x1920 at around $1400. If you are a display enthusiast (as I am) this is a price point you can't ignore.


Why you should wait

Refresh rate: 60 Hz vs 30 Hz. Many of the current batch of 4K Monitors can only disply at 30 Hz when using their full resolution. Most majority of people are going to be used to getting 60 Hz out of their displays which results in a fluid, smooth experience as windows are scrolled or moved. With 30 Hz most people notice that everything seems “choppier” and this can prove very irritating. The reason for this is that these monitors only support the current HDMI 1.4 spec, not the soon-to-arrive HDMI 2.0 specification. (Note that the Samsung U28D590 is supposed to support 60 hz when using displayport)

Color accuracy. Check out this article and look at the color accuracy section. It's not acceptable if you care about your displays.

It isn't all about the hardware. Software support and compatibility matter. Windows and apps that run on Windows are catching up to dealing with High-DPI monitors like these 4K Displays. At these resolutions you'll almost always want to run with “High DPI Scaling” (or whatever it is officially called in Windows) enabled. However, apps take time to correctly handle these displays, and they still sometimes don't look right. Check out this description of how Visual Studio 2013 has improved its high-definition support and see how complex this can be. If you really do want to try one of these displays, turn on High DPI in windows and make sure you run your favorite applications –  you will likely find some don't respond well to it. This situation will eventually fix itself (for most applications) as enough developers start using this hardware an designing for it. If you are running older software –  you may find using these displays difficult.

Not all of the 4K displays are IPS. Looking at you, Samsung U28D590.


My Requirements for a 4K Monitor

When it's time (hopefully later in 2014) Here's my checklist:

  • IPS Panel. (Remember we hate TN displays)
  • LED Backlighting.
  • 1” Cabinet Depth
  • 3840x2160 at 60Hz (via DisplayPort and HDMI)
  • Built-in speakers that can play the audio via DisplayPort and HDMI connections
  • At 28” the cost needs to be about $700. (the basis of this cost is that it should replace my current favorite monitor the hp zr2740w –  which I believe is a fantastic high-end display at a great price)
