• fabs() – Gets the absolute value of the value in parentheses. Works like ABS() function in Visual Basic. fabs(-123) = 123, fabs(34) = 34.
• ceil() – Find the ceiling integer. Kind of like rounding up. Same as INT(x+1) in Visual Basic.  ceil(3.1) = 4.
• floor() – Find the floor integer. Kind of like rounding down. Same as INT(x) in Visual Basic. floor(3.6) = 3.
• exp() – Find the exponential value.
• pow() – Raise a number to the power. pow(3,6) = 3^6 in Visual Basic.
• rand() – Generate a pseudo random number. Function is RND(x) in Visual Basic. A good discussion on random numbers in Objective C can be found here.
• srandom() – Generate a seed for the random number generator. This is done with the Randomize statement in Visual Basic.
• sqrt() – Find out the square root of a number. sqrt(x) = x^(1/2) in Visual Basic.

Power Users and Developers: Making customized Apps Using Microsoft Office
Those of us who have the responsibility of producing customized Excel workbooks, and Word documents that essentially have become small powerful applications in their own right are always looking for ways to make the tools we build in these Microsoft Office products more powerful, easy to use, and more like actual stand-alone apps. One of the ways I looked at enhancing the “tools” I created was by adding a tool bar to an Excel workbook for example. I first did this myself in Excel 2003. It was tedious but doable. One draw-back in the way tool bars were done back then is that the changes applied to the whole app (Excel or Word), and one screw-up on your part could truly clobber Excel or Word’s tool bars and menus system wide.

A New Way of Doing Tool Bars in Office 2007
In Office 2007, Microsoft changed how their user interface worked. And they changed the scope of the changes. If you were going to screw something up for your tool bars now it would only be with one document file, not the entire system. Customizing this tool bar was more flexible. You could do much more with the new tool bar than the old version (the new tool bar Microsoft calls a ribbon). The Technology behind the ribbon they call RibbonX.

Drawbacks & Limitations
The the main draw-back to the new system was that you cannot modify existing tool bars or create new tool bars purely using VBA code (once the toolbar was created though you could write VBA code to modify it and response to events from it such as mouse clicks). You need to know a dialect of XML created by Microsoft for defining these ribbon tool bars, and you needed to know the steps for embedding or updating this XML inside the document file. You could do it manually (in which case you are almost sure to miss something and screw it up), or you could use a tool called the Custom UI Editor for Microsoft Office to do your toolbar design in. This tool isn’t real great but it beats manually editing by a long shot!

The Book I Use to Answer My RibbonX Questions If you want to create your own customized tool bar ribbons in Office, you can find some information out on the web on how to do this, but by far the best source of information that I have found is the book: RibbonX – Customizing the Office 2007 Ribbon, which is by Robert Martin, Ken Puls, and Teresa Henning. It covers how the technology has changed for tool bars from Office 2003 to the present day, goes into the strengths and weaknesses of the old and new ways of doing this, and then proceeds to dive into the task of showing you how to create your own custom Ribbons or modifying the built in ones. Most of the work that you will do is editing XML files. It then shows you how to write VBA code  that can show/hide enable/disable ribbon tabs and/or ribbon controls, update label contents on ribbons, and respond to user input (such as a user clicking a button).

The Intro to VBA is Great!
Chapter 4 is a whole chapter on VBA in general (not just one using it to handle a ribbon). This is some of the most clearly written text I have ever read on the subject. In my opinion it is better than the content of some books which are solely supposed to be about VBA! So, even if you don’t plan to spend a lot of time creating tool bars for your Excel or Word documents, buying the book for this chapter (and the other chapter on advanced VBA) alone is worth it.

Finally, it is a Reference Book
Microsoft has different XML tags and attributes for creating ribbon tabs and all the various controls on the ribbons. At the back of the book are tables of all these items. Some of the attributes take one of many pre-defined constants that Microsoft has provided. The book contains tables of all these values too.

Chapters in the Book:
• Part I – The Building Blocks for a Successful Customization
  • Chapter 1: An Introduction to the Office User Interface
  • Chapter 2: Accessing the UI Customization Layer
  • Chapter 3: Understanding XML
  • Chapter 4:Introducing Visual Basic for Applications (VBA)

The book is RibbonX: Customizing the Office 2007 Ribbon and at the time I published this post it was $25.06 USD on Amazon (oh and its available on the Kindle too). I give it 5 out of 5 stars. If you do any Office VBA stuff and want to have custom tool bars in your Office documents, I recommend you get this book.

I am amazed at how creatively musicians from North Point Community Church use these devices… picking specific apps for different instruments, and the creativity of the app developers who dreamed them up. Just cool!

The musicians needed to practice a bit more on the middle song, but the first and the last songs were very polished and professional.

Anyways everybody, Merry Christmas!

A few years ago, I am not sure just when or how, I stumbled upon these videos on Yahoo where programming legend Douglas Crockford gave very interesting and insightful lectures on the JavaScript language. It has been a bit tedious to find part X of a lecture and I would think about creating a page on the web that embeds all these videos in a way that makes watching them easier to do. To curate this content as Robert Scoble might say. Well after all this time I am doing just that in this post.  I think that if you are a programmer and you use JavaScript in any fashion that this information is really useful. Both to learn new things, as well as for review.

Doug’s lectures have been a great help to me to get an intuitive knowledge of JavaScript. Even if no one else goes to this post I will so that I can review his lectures when I please all in one spot. I hope you enjoy them in this “curation” (I know that I will)!

FYI: If you are reading this post in a Feedburner email, you probably will not see the videos and have to click the link that takes you to the actual post on Chomer.com

  “JavaScript is a language with more than its share of bad parts. It went from non-existence to global adoption in an alarmingly short period of time. It never had an interval in the lab when it could be tried out and polished. JavaScript has some extraordinarily good parts. In JavaScript there is a beautiful, highly expressive language that is buried under a steaming pile of good intentions and blunders. The best nature of JavaScript was so effectively hidden that for many years the prevailing opinion of JavaScript was that it was an unsightly, incompetent abomination. This session will expose the goodness in JavaScript, an outstanding dynamic programming language. Within the language is an elegant subset that is vastly superior to the language as a whole, being more reliable, readable and maintainable.” – Google Tech Talks

This is a guest post from Monica Lewers, who for the past few months has been my personal trainer. Her clients keep signing up with her again and again. For one reason: she gets results. In this article she provides some tips on how to not   “fall off the wagon” and stay healthly when you are traveling.

Enter Monica Lewers:

I have had discussions with many of my clients about keeping up their exercise and eating regimens while on the road. Whether the trip is for work or pleasure, here are just a few of my tips to keeping on track:

1. Be your own boss first
   Put on your job description – “must perform some form of ‘getting the heart rate in the range,’ ‘strength,’ or ‘flexibility’ exercise for thirty minutes at least once every couple of days while on the road.” Some of you may say, “but I don’t have the time.”  Yes, you do.  It is not a matter of having it.  It is a matter of making it.  Make the time to demand good work from you, for you, first.  Why does your job, your boss and your customers deserve the best of you and not you deserve the best of you also?  Health is not an option. It is mandatory.  It is a privilege that should be treated as such. Where do I find the time when on the road you ask?
   
   • While I wind down watching the news or something else on TV in my hotel room.  I ask for extra towels and use them for mats on the floor.  I bring exercise DVDs and pop them into my computer.
   • Staying at a hotel that has a 24-hour fitness room.  It doesn’t have to be fancy, just functional.  Ask a personal trainer for some creative regimens to get full body and good cardio workouts on limited equipment.
   • Taking my jump rope and going outside early morning (even if it is the parking lot). Walks and jogs count too.
   • Researching where the nearest health club is.  I plan my departure/arrival so that I can go outside of the times of my scheduled events and/or travel times.
   • Develop great relationships with my clients and traveling colleagues.  When I do, they tend to be more understanding when I excuse myself a few minutes short from the end of the extended dinner chats or social drinks for something “heart healthy.”  And the more your body looks the part, or your enthusiasm demonstrates your commitment, the easier it is for them to understand and even be inspired.
     
      
2. Being polite does not mean you have to be rude to yourself
   Many of my clients have shared with me that they don’t want to be rude at family events by not filling their plates with the wonderful (but not necessarily the lightest, heart healthy, or personal physique goal matching) spreads that your loved ones have put together.  Others have noticed that often the choices at business related events are on carbohydrate, fat, and/or refined sugar overload.

   Again, don’t fret.  Here are some of the things that I do:

   • Focus on the fruits and veggies.  Go for the raw when available and leave the dressing and dips alone.
   • Get only a spoonful/sliver of the indulgence foods.
   • Share a piece of dessert with a colleague or loved one.
   • Go for whole wheat or whole grain bread.  Consider making open face sandwiches by taking a piece of the bread off, and leave those tempting rolls in those pretty baskets.
   • When the food is on the “better for your goals” side, eat the right meal amount and let good ole’ fashioned take home containers be your handbag for the rest.
   • If possible, eat before you go to the event or have healthier choices waiting for you back at home or at your hotel room to complete your daily intake.
   • Share in the meal preparation by making your goal-friendly dish for the family.
      
   Often times, someone brings up my eating habits on-the-spot.  They become a topic of discussion that leads to a great conversation about health, diet and exercise.  I never criticize the food or others habits.  I just educate them why what I am doing is best for me – if they ask.  If like me, you gain energy from how understanding family and co-workers become when you share knowledge and results as the basis for your dedication, then you will be motivated to keep on keepin’ on!

    

3. Identify a place to purchase better choices of food
   When I have a trip planned, I will spend the extra time to locate the places where I can get meals that meet my personal goals.
    
   • Grocery and convenient stores are great places to get wraps, salads, naked juices, prepared (grilled or baked ) chicken and such that store well in the hotel room.  (Still read the nutrition labels though!) Fill your ice bucket and use it as a mini-frig.
   • When at a restaurant, order double of the foods that work towards your goals and use my favorite handbag – the take home bag.  (For those new to business, protocol dictates you order the extra food on your dime…)
   • Buy extra at the airport.  Have protein bars, burritos (minus sour cream), bananas, etc. and have them available to eat on the plane, car, etc. and for when you get to the hotel/destination.  Eating/snacking every couple of hours helps so much to curb your appetite in the direction of your goals.
   • Stay at hotels with a kitchen (or at least a frig and microwave) or spend the extra money for hotel food that is goal friendly.
      
4. Cut back on the drinks
   Drinking alcohol is not a requirement.  And drinking water, sipping on a pop (soda) – if you must – works just as well.  Enough said.
    
5. Whatever motivates you – Use it!
   Find what gets your underwear in a bunch and release that negative energy into positive exercise or staying focused on your diet.  For me, I despise love handles on me and I love looking tone (ok, “cut” ).  I love having health stats of a grade school age person. I love the fact that I have saved my life by shamelessly making my health a top life objective listed privately on every one of my job descriptions. If I know that eating this or not doing that impacts any of the above, then you know what – I listen to my gut before my gut shows its ugly self as a side order of flab.

Background:
I downloaded Apple’s iOS SDK 5.2 and installed it on my Mac. After that process was over , I decided to load an existing project of mine into XCode. Ok, good. Then I tried to do a build. Kaboom! It did not work! No worries I thought, I will just go to the drop-down and pick the latest SDK 5.2. But the option was not there! The thought came to me that I might have to create a new project and import all my files from my existing project just to get it to work. Not a very nice thought to say the least!

Unexpected Source for a Solution
Approximately a day later I got a book I ordered called Learn iPhone and iPad Cocos2D Game Development
by Steffen Itterheim. I bought this book with ambitions for writing my own game or two.  Anyway, in chapter 2 “Getting Started” on page 17, the author of the book described the solution to my problem and yours: how to fix this Base SDK Missing problem.

Here are the step by step instructions to fix your project:

1. Load up the project in question into XCode. …   Also notice I highlighted the message in question in green:.
   .
2. On the XCode menu bar, pick the Project menu option..
   .
3. The third option from the bottom of the Project menu is Edit Project Settings, pick it..
   .
4. The Project Info window will appear. There are four tabs at the top: General, Build, Configurations, and Comments. Make sure that the Build tab is selected.
5. The Top Group on this tab is called Architectures. The third item under Architectures is Base SDK. You will see which SDK it was trying to use with the word (missing) next to it.  … Notice below I’ve highlighted the Build tab and have green arrows pointing to the Architectures group, the Base SDK option, and the iOS 4.0 (missing) to have them stand out for you..
   .
6. Click on the Value column for Base SDK to get the following menu:.
   .
7. You will notice various SDKs available to you to use. In this case we are not interested in any Mac OS X SDKs, but rather a valid iOS SDK value! The only one available in our example is iOS 4.2 in this case. So, we would pick it!
8. The Base SDK value will now be set to iOS 4.2. (see screen shot below)…  The value is automatically saved to the project so there is no need to do a save.
9. Close the Project Info window. The main project window itself will still be unchanged. It will still say Base SDK missing. Do not freak out! Your changes have taken effect. All you need to do now is close and reopen your project and you will be good to go!

While in many ways 2010 was a tough year, there are still many many things to be thankful for. Here is a list of things I though of for myself:

• A job. Not something to be taken for granted these days.
• Food to eat.
• A roof over my head
• A wife that loves me.
• 2 nephews.
• 2 sisters and 2 brother-in-laws.
• My mom.
• Fall colors.
• Fresh clean crisp air to breathe in.
• A good church.
• Good friends.
• A working car.
• walks in the forest preserve.

I could go on a while but I think you get the drift. What are you thankful for?

Here’s wishing you and your family a very happy Thanksgiving!

At the Chicago Marathon there are literally thousands of runners along with a few rollers (wheelchair racers) surging forward in this great race. For the most part these are people who are committed diligently to something and have been training for months just for this race. There is a certain energy of excitement as you behold in person these amazing people executing their plan. And some of these folks are among the greatest distance runners in the world!

There are the elite runners, and the Joe-everyman. They have taken on an impressive challenge: running 26.2 miles and crossing the finish line. I have run and completed the Chicago Marathon two times. It was hard. But there is something to be said for completing a hard and difficult goal and crossing that finish line. This kind of stuff can be drawn upon and applied to other areas of our lives. The Bible even pictures our lives as a distance race where the ones who have gone on before are on the side-lines cheering us on. Willing us to finish the race and finish it well.

Another wonderful thing is the literally hundreds of thousands of spectators who show up at an event like this. Many are there to cheer on friends and family who are in the race. The point is, they show up with an intent to do something positive: to spur on and encourage others. They are also there to be a part of something bigger than themselves.

Go! And be a part of something bigger than yourself! You will have to do a little planning. Here are a few interesting points and tips for going to see a  marathon live:

• The cost of watch a marathon is free. You don’t have to spend money to get in a stadium or any other venue. This is an opportunity that many can take advantage of regardless of income.
• Find out the start time of the marathon and expect to be there at least an hour early.
• If at all possible, take public transportation to the race. This especially goes for large races such as the Chicago Marathon where the traffic around the race can be awful. Just think about all those people coming to run and watch the event and all the roads blocked off from cars so that the runners can use them instead!
• Try to get a map of the course… do this before race day. You can find information like this on the race’s web site. Most of the time a long course like this will be in the form of some sort of loop where the finish line ends up being not far from the starting line. If you plan things right, you can see the beginning of the race as well as others (including wheelchair and elite runners) crossing the finish line.
• Watch for two or three different vantage points along the course keeping these points close to the middle of the course’s “loop.”
• As far as roads in the loop, position your self of the side of the street that is outside the loop or you might end up stuck in the middle for 20 or 30 minutes waiting for 50,000 runners to go by before you can cross the street!
• Many runners have their names on their shirt to provide you with an aid to cheer them on. Take them up on it and get involved in this simple way. “Go Mary!” “Go Joe!”
• Take it all in. The cheering and shouting crowds. The ringing of cow-bells. The sirens. The pace cars. The racers.
• Meditate on the thought that thousands of people this day will attempt and complete a hard task. Some will be in pain, tired, but they will joyfully cross that finish line. It is something that no one can take away from them!
• And finally, later, after its is long over. Deliberately relive those moments and think of those “marathons” each of us has in our lives and the joy of coming through and crossing the finish line!

If you have ever been to Chomer.com before, and now have come back, you will notice that things look a lot different. I’m not done with this spiff-up by any means, but it is well along the way. I think that visually it is a big improvement. Also I am using a Like button for Facebook on posts, and a Retweet button for Twitter. So I’m beginning to get some of the social aspects covered too. Why the social aspects? Its a good way for people to spread the word about content on this site if they find it useful.

A Reality Check
Originally, I had grand ideas of how I was going to re-code the site from scratch, creating this awesome content management infrastructure that would knock everyone dead with amazement. I needed to wake up and smell the hummus!  I needed a nice looking, and working site now! I must say I have avoided posting for awhile due to the fact how embarrassed I felt about my site. So, I am going with a site that is for the most part a WordPress blog. As for the layout and styling of the pages, I got have lot of inspiration from Tim Ferris’ FourHour blog and some stuff he wrote on having a successful blog.

More Work to Go
The header still needs at least one graphic, stuff does not align quite right in some web browsers, and there is more stuff I want to add to the side bar but things are moving along nicely.

As I began refining some sample code for making Universal Apps for the iPhone and iPad, I sought a way to make my code as concise as possible. I needed to determine if the app was running on an iPad or iPhone/iPod Touch and use it to my advantage. This basic information is contained in the UIDevice class.

Unfortunately, using:

         [UIDevice currentDevice].model    

did not do precisely what I needed to do. I needed something specialized. I wanted to add new functionality to the UIDevice class as if it had been there all along.

Looking for Solutions
A few months back I ran into a code sample that adds functionality to the NSDate class called NSDate+Helper. This class, created by a programmer named Billy Gray was my first exposure to a wonderful feature built into Objective C called Class Categories. When I saw how one could do this, it set the wheels turning in my mind at all the possibilities!

In this tutorial I am going to show you how to use class categories, and for our example we are going to add functionality to the UIDevice class for use in ultimately creating a sample Universal App.

Sample Code Info:

Getting Sample Project Source Code & Running it in the Simulator
It would be handy for you to download a copy of our Universal App project to look over and try out. In order to really use it you will need to have an Intel-based Mac computer, and XCode 3.2 or better installed on it. Once you have done this,  you will be able to run it in the iPhone Simulator.

Make sure when running on the simulator that you set the proper build version before doing a build:

Simulating the app running on an iPhone:

Simulating the app running on an iPad:

Running the Sample Project on an Actual Device
If you want to run the project on an actual device rather than just the simulator, you will need to be a paying member of the Apple Developer Network ($99 a year at the time of this post). And you will need to have gone through the hoops of setting up your certificates, app record, and provisioning. … We are not covering any of this getting on the device stuff in this tutorial.

At least you can run the project in the iPhone Simulator for free!

What is a Class Category?

• You use class categories to add new functionality to an existing class. This could be one of your own classes, or it could be a class in Apple or someone else’s API.
• You do not have to sub-class the class you are adding to.
• You can add the new functionality in such a way (inside your project) that it seems that the functionality was there all along!

Step 1: Come Up With A Category Name
When creating a class category you are adding some sort of new functionality to an existing class (without touching any of the code actually in the existing class)! If you were to describe in a general way what that new functionality was, how would you phrase it? What “category” would it fall under?  This is something you make up. I make up some sort of camel-cased phrase for my category name. In the case of my new functionality to add to UIDevice, I thought that MyDeviceType captured it well. Perhaps if I had thought about it longer I could have made up something better! But that is what I came up with so that is what I used!

Step 2: Create a Group in Our Project to Place our Class Category in (optional)
The first thing you may want to do is create a new group (folder in your project) to place it in. This is optional, but it can make finding it easier as well as providing some form of internal documentation.

So, for the sake of argument, let’s say that this is what you want to do. Let’s go through the steps needed to do this:
- First of all click on your project file item (in examples shown in the screen shots, this is “classcat”).
- Then control-click on it again to bring up a pop-up menu.
- Click the Add option at the top of the menu…
- Then click the New Group option (see screen shot below)

 

 

 

 

• Add new functionality to existing classes (especially API type stuff) like we did in this tutorial.
• Break a large class up into separate files grouping various blocks by function “category.”
• Can you think of anything else?

Hope you find this tutorial useful. Any questions? Ask away. If you could rate my Youtube video that would be great too! 

In the next tutorial we will be talking about the structure of a Universal App.
