Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. The GPS provides critical positioning capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.

Adafruit DS3231 Precision RTC FeatherWing

A Feather board without ambition is a Feather board without FeatherWings! This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator to any Feather main board. This RTC is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw.

With a CR1220 12mm lithium battery plugged into the top of the FeatherWing, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.

Momentary Pushbutton Switch

This is a standard 12mm square momentary button. What we really like is the large button head and good tactile feel (it ‘clicks’ really well). This button is great for user input on a PCB or a good, big reset button on a breadboard. Breadboard friendly!

Fun with browsers and WordPress

Apr 30, 2010 @ 20:40

It has been one of those days. Somebody reported to me last night that the theme of our <a href=”http://www.igourmand.com/eatdrink/”>food and wine blog</a> did not display the first photo of any page correctly. The first image appeared after a huge space. The problem only happened with Internet Explorer and everything was fine with Firefox. Thus became the quest early this morning at 8am and I started tracking the problem.

I first thought that it was some “Div” problem as the theme used was one that I had made over 5 years ago. I recently rewrote it to change the look and then I rewrote it again last week to bring it into line with the current WordPress theme architecture. I had yet to polish it and finish formatting it and commenting it properly, so my logical thought was it was just some error in one of the PHP files of the theme. I even remembered checking it with various browsers just last week to make sure there was not such a problem, but since I have been doing small incremental update maybe some little error slipped in and I did not catch it.

I first checked the source code in the browser to see if I could find something wrong there. I used a few automated HTML formatter and the results were dismal. If somebody has a good HTML formatter that actually works to recommend, please let me know.

I ended up formatting everything by hand and after reviewing the code found out that there was absolutely nothing obviously wrong with it, and nothing that would explain the discrepancy between Firefox and IE. I had a hunch that the problem might be with the sidebar code, so I disabled it and low and behold the huge space before the first image on a page disappeared. Thus my hunch was right.

I then re-enabled each section of the sidebar one after another until the problem reappeared and finally found that the problem was with the image links I added a few days ago in the sidebar. There is absolutely no reason that IE should behave this way, except that it does not interpret the CSS properly. There is plenty of space for both the sidebar image links and the image in the post, and even if I resized the image in the post to a smaller size the problem continued.

I then starting fine-tuning the CSS and with just a few minor changes of around 15 pixels in one section everything popped back together as it should. I guess that IE is just very bad at properly following the CSS and placing elements on the screen.

Once that was done I decided that since I was in the middle of doing a lot of things with the theme, I should finish it properly. I spent the rest of the day properly formatting the code, changing deprecated WordPress functions to their new versions, profusely commenting the theme so the next time I need to modify things I can quickly find what I am looking for, doing some minor cosmetic changes to the theme, and generally improved its function and look. I still want to spend a bit of time beautifying things, but now it will be a much simpler job after the work that was done today.

What started as what I thought would be a simple job finding a faulty line of code, ended up a day of detective work. The nice thing is that I learned a lot dissecting the more recent template format of WordPress as I had not digged in its depths since version 1.5. It is much more flexible and powerful now and I will go to bed much less stupid tonight after a great day learning new things about the inner works of WordPress. I’m just glad that the work was for myself as I would not have like to explain the reason to justify a full day a work simply to move a picture up in a blog to a client.

Why Consult Ants?

Apr 22, 2010 @ 19:23

As you main have noticed the blog is launching its new look today. I spent the last hour creating a quick and dirty theme for the blogs with a few simple graphics and over the new few weeks I will probably refine the look when I have a bit more time.

Some of you might be wondering why I named the blog “Consult Ants”. Besides the obvious bad pun, the name reflects my view of what the consulting business has evolved over the last decade. When I started as a consultant over 25 years ago, the profession was very different and was guided by some standards, which of course a lot of consultants were not following and giving a bad name to the profession, but it did meant something to the users of our services as the consultants that were doing a good job were respected in the industry and by our clients.

Today it seems that everybody and their cousins is a consultants, and just mentioning the name “Consultant” brings a bad connotation to a lot of people’s minds. It used to be that one would rise to the top of their field and then become a consultant, but now I see teenagers that label themselves consultants and want to sell their services at $5 an hour. That is not good for them, their clients, and for all consultants. I will rant and rave about this at length in the future, but this is what brought the name of this new blog to my mind. It seems that in lots of people’s minds us professional consultants are like a bunch of little interchangeable ants that are just running around in circles doing work and that every ant is doing the same job mindlessly. I want to bring this piece of information to the surface and dispel it, thus the name “Consult Ants” is there to bring it to the attention of most.

Since this blog will not be a structured one and will be more of a stream of mind type of blog, I am not sure exactly where this will lead, but bear with me when I try to find its directions and feel free to participate in the comment section.

Welcome to our new consulting industry blog!

Apr 20, 2010 @ 12:35

I have been blogging for over 5 years now in other venues and I thought that it was time to post my thought about what has been my main business for over 25 years. I started as a food-wine consultant back in the early 80’s. I was also active in the emerging field of computer graphics and animation at the time and also started to be more and more involved in the IT world as I had trained as a programmer at university. By the dawn of the 90’s I was a full time IT consultant/programmer/graphics/animation specialist. Then the industry changed rapidly with the event of the big Internet crash of the late 90’s and I became a software developer and launch my own line of products. Now I am back where I started and I am a Business/IT/Programmer/Hardware/Robotics/Graphics/Animation/Web/Food/Wine specialist.

I have seen many trends come and go, good and bad, and lived through many major industry changes. I do deplore some of the current state of the industry, and applaud some of the new trends. My wife had been telling me for years to write about the the industry as we discuss things a lot and she always tells me that I was born to teach, or preach when I get excited about a subject. Since my motto has always been to learn something new daily, and that a wasted day is one where you learn nothing new, I decided to share some of that hard-earned let’s call it “wisdom” for lack of a better term.

I know that I am considered as a dinosaur in this business where you are considered old when you hit 25, but there are some of us old fogies at over twice that, that are still active and can still provide a full contribution to this or these fields.
