There is a Grown-up

There is a grown-up at home
Telling me what to do.
Do I hate the grown-up?
The grown-up is wise.
The grown-up loves me.

I am safe in the grown-up's care.
I love the grown-up.
I am thankful.
I am....

Yasi Oral Irrigator review

I was sent a free Yasi Oral Irrigator Model YS831 to write about. I made a video review, and this post is to summarize my review. The only comparison I have for this irrigator is my Waterpik Model WP-100W irrigator, which is the third of the same model I have bought.

Update from Yasi: this is a travel irrigator, and they also have an irrigator with a much larger tank here: This model I reviewed is comparable to this Waterpik model , and I suspect the only unfavorable comparison with that unit would be the uncomfortable standard tips included with this Yasi irrigator.

Introduction to the Real Estate Non-commoditability Market Inefficiency

What I mean by non-commoditability is the inability of some types of merchandise to act like commodities in markets. It's too long a word. Maybe you can tell me the correct word or a better word.

How I made Youtube videos in May 2017

Yesterday I used CamStudio and Youtube/editor to make a Civil 3D Retention Basin video. CamStudio worked great, but I could not remember how I edit out dead spots and mistakes before.

Now today I started CamStudio and all my options are lost. So let's see what I have to do.

-You must not exit with the X or settings are not saved. In fact, they may be reset. I seem to recall this from my previous stint as a videographer.
-Set the Cursor options to greenish and as large as possible with visual click feedback.
-Installed CamStudio Lossless Codec v1.5 and set it current.
-Right-click visual feedback doesn't work.
-I am using version 2.7.4 Build on Mercurial release: r354
-I installed and am using CamStudio Lossless Codec v1.5
-I set the frame rate to 8/sec so I would not look so mouse hyper.

I am trying to use Avidemux to edit the dead parts from the video.
-Avidemux did not create a shortcut. I have to open it from the Program Files folder.
-Not too pleased with Avidemux. Only trims to index frames.

I ended up making the videos really short and doing no editing.

How to size and calculate a simple storm water retention basin on an existing terrain with Civil 3D

Assuming you already know the Retention Volume Required (it's an Arizona thing), you need a fast way to design a retention basin if possible. Complex retention basins in tight areas have to be maximized according to the available room. Then Civil 3D volumes below a level HW surface have to be taken to determine the volume. And there is not much you can do to get more volume without spending money on retaining walls or underground retention. But some other basins are in wide open areas, and they can be relatively simple shapes. For those you need a fast way to get them drawn to the required volume.

HEC-RAS 2D Land Cover from AutoCAD

I had a bit of trouble getting a Land Cover map from AutoCAD to HEC-RAS today. I made a map, but HEC-RAS kept telling me the file "has 0 features". It turns out I needed to set the project projection to the projection exported from AutoCAD with the Land Cover map.

How Roughness and Loss Coefficients are Applied to Reaches in HEC-RAS

It's really hard to find a clear explanation of how roughness and loss coefficients are applied to reaches in HEC-RAS.  I ran extensive scenario testing today and here are my results.

Automated AutoCAD GIS export to Maricopa County DDMSW hydrology

I have finished the first version of the open source work-flow optimized application at AutoCAD Wiki.  It works like this:

Tilde conflict between AIA/NCS layer name specification and AutoCAD wildcards

National CAD Standard (AIA) layer name specification version 6 (2014) allows us to use only alphabetic and numeric characters and "~" (tilde) in layer names.  But the tilde has a wildcard meaning in AutoCAD.  What are we to do?

AutoCAD Civil 3D in Windows 10 Qsave and Xref Load Performance Quest

I am on a quest to improve the performance of my AutoCAD Civil 3D 2016 in Windows 10.  I am tracking all my attempts in a Google Spreadsheet with records of what effect each has.  Trying to be a good scientist.  Feel free to check it out and comment.

How to verify my digital professional seal on an engineering plan

For the past decade my engineering plans have been digitally signed. This means that the official copy of all plans I seal is the digitally signed PDF file.

AutoCAD Dimscale 0 - What's really happening

As of AutoCAD 2017, the AutoCAD help is wrong in its description of 0 values for dimscale.  Here's what's really going on from what I can tell.

How to map a drive letter to a local Windows folder

We freelancers are using Dropbox as a virtual network for our civil engineering and AutoCAD Civil 3D files. And it's really great (especially since I have a daily backup set up).  But some programs want us all to have the same absolute path to our files.  To do that, we have to each map our Dropbox folder to the same virtual drive letter.  Piece of cake!

Turn and Drop: A Counter-infiltration Tactic for Non-violent Direct Actions

Arab Spring was yet another example of the irresistible trend of non-violent populist movements toward violence.  Marginal violent actions by infiltrators or violent factions have explosive power to hijack and doom revolutionary movements.  The toolbox of rigorously trained non-violent revolutionaries is incomplete without effective counter-infiltration (counter-hijacking) tactics.  This post presents one: Turn and Drop
