I love teaching knots part 2

Yesterday, in my log I love teaching knots I forgot to mention the Sheet bend and the Sheep shank. Although these knots are used less frequently, they are very important knots too. The Sheet bend is used for joining two different sizes of rope together. The Sheep shank is used for shortening a rope without cutting it. The Sheep shank can also be used to temporarily work around a damaged part of a rope without losing the ropes strength.

While writing this article I found two websites that had some pretty good examples of tying these knots.

  1. I Will Knot! – has little video snippets that breaks down the knot tying into little bite sized pieces.
  2. Knots Gallery – has nice animations of various knots being tied

One note about the knots, the “Square knot” that is taught in Boy Scouts is referred to as the “Reef knot” elsewhere.  So if you want to see what that looks, you’ll have to lookup Reef knot.

In Boy Scouts we try to have the Scouts learn a skill, master it, then teach it to younger scouts.  In order to teach it, they need to be able to explain it in simple terms and demonstrate it in as simply as possible.

While it is great to see a student experience that moment of epiphany, when the light bulb goes on, it is even more rewarding to watch when the student becomes the teacher.  They teach the skills I have taught them, then their students experience that moment when they understand.  I hope these skills will be passed on to future generations.

I love teaching knots

Over the years, I have taught many different scouting skills to Cub Scouts and Boy Scouts between 9 to 18 years old.  One of my favorite subjects to teach is knot tying.

One of the main reasons knot tying is my favorite, is because once someone learns the basics, they will be able to tie more difficult knots based on the foundations they’ve already learned.

The square knot is one of those classics that every scout learns first.

The knots based on the half hitch are:

  • Clove Hitch
  • Two-half hitches
  • Taut-line hitch

The timberline hitch is one of those knots that is simple once the knot tyer gets the hang of it, then they use a half hitch to keep the knot taught.

Probably, one of the most complex knots I teach is the bowline.  Instructors have different methods of how to teach this knot.  Some like to teach it where the rope is around the person.  Others like to have the student learn when it’s not around the persons body.  When I teach this knot I explain that it’s a rescue knot & why it’s important to tie it correctly.  I also take the time to teach them how to tie it both ways around their body & around someone elses body.  Hopefully, if they ever have to use it, it would be to rescue someone else.

Another interesting thing I have come across when teaching knots has been if someone is left-handed.  They usually tie it upside down.  To most instructors, they sometimes get frustrated because the student isn’t getting it the way the instructor is teaching it.  But when I see the student having difficulty, the first thing I ask them is whether they’re left or right handed.  I have been gifted with being left handed, but I learned how to do everything with my right hand.  So, I’m kind of ambidextrous.  I adjust the lesson toward their understanding and then they get it.

I think probably the most rewarding part of teaching knots is when the student has an epiphany and have learned a skill for life.  I love to see it when the lights go on 🙂

Till next time,  I’ll be teaching this skill for life

MediaShout Rocks: It’s a presenters dream

Have you ever been in the situation where there are several Powerpoint presentations that need to be presented in the same meeting?  Or how about that last minute correction to the powerpoint  just before a presentation starts.  Or someone brings in a CD with a bunch of images and wants you to display them in a particular order.  When you’re in the Multimedia booth, it seems to happen all the time.

A few years ago, I was introduced to this wonderful presentation application called MedaShout.  It helps make the Multimedia staff look good.

Some of its features are:

  • drag and drop PowerPoint files, image files, video files into a single script 
  • create text objects, much like PowerPoint
  • re-arrange the media objects order by dragging them around in the script
  • add fade to black or white
  • do timed transitions or synchronize them with sound files
  • Activate any media objects at random
  • Announcement mode
  • Create Text slides on the fly
  • Lookup & display practically any media file on the fly

Some of the other features include,  multiple screens, the script screen, a control screen and the live screen.

I recently heard that version 4 is available.  It has some new features that haven’t been available until now.  Stage Display.  This is useful when you have a audience projector and a speaker projector.  Just the text without graphics can be displayed on the speaker’s projector.  Another feature, if you’re already familiar with MediaShout is Section Cues for grouping media presentation activities together.  And finally ability to import PowerPoint into the system so it can separate the text from the graphics to take advantage of the power of MediaShout.

I’m pretty excited about this updated Multimedia tool.  I’m going to recommend that we get the upgrade.

Till next time, MediaShout Rocks

Some programming required

I recently experienced a missing page error on my website.  It didn’t match the theme at all.  I was kind of disappointed, since the rest of theme had been done so nicely.  I figured, no problem, I’ll just install and activate one of them handy dandy Plugins to resolve the error and then it will display nicely within the the content window of my theme.

I’ll admit at the moment, I’m a newbie to the WordPress framework.  So, I have a little learning to do.  After doing a some googling on the subject, I discovered, that the missing file error is handled in the theme’s 404.php file.  Usually, the theme author modifies the page to be minimalistic, blend in with the theme and display a friendly message to the user.  Unfortunately, the error page in my theme must have slipped through the cracks.  It didn’t quite fit in, so I set out to create the error page that would fit my needs.

I found a great article Creating an Error 404 Page that gave some great suggestions.  I ended up copying the default page, then pasting into the 404.php file.  This got me part of the way to my pretty error page.  But, it wasn’t trapping the errors, like I had hoped it would.  This is where I ended up installing and activating the “Useful 404’s module” at http://skullbit.com/wordpress-plugin/useful-404s/

This module maps the different kind of error codes and information into relatively useful messages.  All you have to do, is paste in the code <?php useful404s(); ?> at the strategic point in the 404.phhp file to make it all happen.

This expereience has piqued my interest in what it takes to develop Wordpress themes, Widgets and Plugins.  I plan to increase my knowledge on customizing my WordPress environment.

Till next time, I’ll be learning more about WordPress

User interface reboot

During my career as a software engineer I have been frustrated most by user interface design of consumer electronics.
My biggest pet peeve is when a device is partially functional.  The user interface appears to be running or kind of running, you can touch a button or touch the screen or click on a remote control and see some response, but it’s obvious that the device is not really performing the requested task.  It’s stuck somewhere waiting for an event that may or may not happen.  The old “race condition” has reared it’s ugly head.  What caused it?  WIll it ever get out of that condition? Who knows?  Apparently the code doesn’t have a watchdog timer to catch this condition.

I don’t mean to pick on TiVo because I really do love my DVR. My experience is still fresh in my mind, so that’s why I’m using it.  They do use some kind of watchdog timer, because when it hangs for a period of time, the TiVo will reboot by itself.  The only thing, I wish they had designed into the unit was a reset/shutdown button or at least an on/off switch in the power supply. Computer manufacturers do it, TiVo is basically a computer with a specific purpose. There are two ways to force a reboot of a TiVo. The first way, if the menus are functional is to choose reboot in the setup menu. The other way to force a reboot on a TiVo is to cycle the power. There isn’t a switch on the device, so the power plug must be unplugged, then plugged in again. I agree, it might be admitting that problems do occur, but at least their customers would not be so irritated whenever a problem required a reboot.

I have had to do this with some DVD players as well.  Something happened when a DVD was inserted and it never quite recovered.  The buttons became unresponsive and the only way to fix it was to cycle power on the unit.  Of course that meant unplugging the device, then plugging it in again.  We grew tired of this behavior and ended up recycling it.

Handheld devices aren’t much better.  Many handheld devices don’t seem to have a reset buttons on them.  When there is one, I have been very grateful when I needed to use it.  In most cases, when something does go wrong, you are required to cycle power by removing the battery, then waiting for 30 seconds, then replacing the battery.  This works in most cases, but what about the case where you have a built-in battery with an external power source.  If you’re lucky it was designed to reboot when the power button is held down during the display on event.  I am just suggesting that perhaps software designers should add a menu item in system settings or diagnostics mode that would allow the user to reboot their device.  The payoff would be huge and result in less customer frustration.

Till next time,  don’t forget your users’ when you design the product
