A New Android Cell-Phone

I'm creating this note on my Samsung Galaxy S2. It's a great little cell-phone with a fast processor, lots of storage, and a fantastic display. I purchased it from Amazon, and thanks to the best feature of cell-phone provider T-Mobile, SIM Cards, all I needed to do was transfer the card from my Charm to the SGS2.

Google+

Thanks to a kind invitation from my Facebook friend Christopher Harris, I had a wonderful opportunity to play around with Google's new service (currently in beta I believe) called Google+. It is similar to Facebook with hopefully a few nice additional capabilities. So far so good! :)

Emacs

I've worked with Linux for more than a decade but never really settled on a favourite editor. I've worked with vi, nedit, gedit, and even wrote my own (running under zForth for Linux) but now I've settled on Emacs. I like the power and extensibility of Emacs and after giving it a trial period of at least one month, it has become my preferred editor/environment.

Using Google's Command Line Tools

I read a neat article today about using the Google Apps via the Command Line. This allows you to directly manipulate Apps like YouTube, Blogger (as I am with THIS posting), Picasa, Calendar, etc. As the article said - don't act like you're not impressed!

The Linux Foundation

I encourage all Fans of Linux to join the Linux Foundation and contribute to the growth of our favourite Operating System. (Tux would be proud of you! :)

It comes as no surprise to anyone who knows me that I am a real fan of CAS ("Computer Algebra System") calculators, especially the HP-50G. I highly encourage all of my fellow HP-50G fans to sign up and contribute snippets of their knowledge about this powerful tool to this excellent Wiki:

http://hp50g.pbworks.com/

I've owned my HP-50G for years and have come to learn many of its secrets and hidden powers. It is my hope and prayer that others who share more than a passing interest in The Queen of All Sciences, Mathematics, and computer-like gadgets that assist us in our Mathematical Recreations would take some time to purchase and play with this amazing device. (By the way, I receive nothing from HP for my endorsement of this excellent product other than my personal satisfaction with it.)

For some people, their recreational time with electronic devices is playing games and everyone has a favourite game.

I am no different as my favourite game is called PROGRAMMING. It's a highly entertaining game, fun to do, fun to learn, and best of all - I GET PAID TO DO IT! I hope that every young man or woman who has interests similar to my own will learn to love this "game" as I do, for it can lead to a great deal of success in life.

Last week, I purchased my latest gadget, an Asus Eee PC 900SD from Amazon/Tiger Direct at the amazing sale price of $219. Wow - now that's a lot of power for a low price! Think about it ... an IBM PC compatable laptop computer with half a gig of RAM, 8GB of fast SSD, a slot for SD cards, a beautiful display, 3 USB ports, Wifi, Ethernet, etc. for just $219 - slightly more than the cost of A GRAPHICS CALCULATOR! Software that can be put on the SSD include many different (and free!) CAS software engines that are superior to any calculator sold today. I can even install and run on it the highly-acclaimed Debug4x HP-50G Emulator that works quite well on WinXP machines (both real AND virtual).

Although it doesn't come with Bluetooth capability natively, it was easy to add it with Belkin's Mini Bluetooth Laptop Adapter, giving me the ability to work with both my Logitech Bluetooth Mouse (that I use with the HP-dv7 2040US) and my Jabra BT620s Stereo Headphones. It works perfectly with these (at the same time) and make for a great PORTABLE set of computing and entertainment tools.

Did someone mention entertainment? The 8GB SSD may not "sound" like much, and it isn't for large entertainment files like music and video collections - but here is where the SD port shines! I can plug in any assortment of SD cards with all of the multimedia data files on the cards - and enjoy them without ever having to copy them to the built-in SSD! Since as of the writing of this blog post, these SD cards are as large as 32GB capacity at under $80, that's a lot of data available on postage stamp sized media that can be plugged into the computer and watched and listened to "on the go" as they say.

The "on the go" expression leads me to another point - I have been waiting and searching, unsuccessfully until now, for a computer large enough to be able to comfortably type on but small enough to fit into my Classic-size Franklin Planner - a mini-briefcase that looks similar to this only mine is black. My search is over and the 8.9-inch Asus Eee PC fits PERFECTLY!

$219 is almost a throw-away price for such power that a mobile knowledge-worker needs - so much so that I may purchase another one for backup purposes. And why not?

As is my custom with every computer I purchase and use, they all have names, and this one is called "Eeek". :)

It should come as a surprise to no one who knows me that the CBS show Numb3rs is my all time favourite television series. Just like the ever-popular Star Trek series of shows, this program is a geek's delight - full of suspense, drama, and enough Mathematics and Computer Simulations to delight even the moribund of geeky viewers.

The story centers around brothers Don and Charlie Eppes and their careers as FBI Agent and Mathematics Professor. All episodes focus on solving crimes in and around the Los Angeles, California area and in using Mathematics to aid in catching the bad guys. It is a geniune pleasure to see intelligent people featured as such - too much of modern TV is centered around boorish characters who almost glory in the comedic nature of their idiocy. Joining Don and Charlie are a diverse mixture of regular characters who add spice to the stories - David, Colby, Lynn, Larry, Megan, Alan, et al. We are presently into season six of the series and some of the characters are no longer with the show, but the central characters remain, as well as the outstanding writing, direction, and production of the finest show on television.

Porting Progress: zForth -> ARM

I've made great progress in working to port my zForth system from the Intel Pentium world to that of the ARM world. The platforms that I use at present are the wonderful QEMU virtualization platform on my Linux workstation, and the T-Mobile G1 cell-phone. Eventually, my goal is to also get it working on my HP-50G calculator in time to present it to the HHC 2010 Conference.

ARM is a powerful and very "clean" processor and I love working with it. RISC machines in general have much to offer low-level systems programmers such as myself and this makes it a fun project to work on.

Porting to a new processor involves many phases which, like scafolding at a construction site, each step is built so that you can "stand on it" and work on the next phase. The first phase was (1) to complete an ARM assembler, after that, (2) to modify the metacompiler so that ARM code is produced, and then with ARM code being produced begins (3) the repeating cycle of run-test-edit on both an ARM simulation environment (QEMU and the Android Emulator) and on the actual ARM hardware (the G1). I've completed phases one and two, with both taking about 6 months of part-time work (roughly an hour a week) and am now in the run-test-edit cycle with threading working perfectly, and some I/O working, but not all. I still have many more weeks ahead of me, but I've "hit my stride" per say, and am enjoying the trip! :)

I ordered my Kindle from Amazon two days ago, received it yesterday, and I thought I would record my first impressions here. Amazon has always been a first-class company and I received a quality product. The first book I downloaded into it was (of course) "Web Geek's Guide to the Android-Enabled Phone", and am looking forward to learning how to effectively use the Kindle with the book that Jerri, Prasanna, and I wrote.

I downloaded some books on my favourite hobby - Mathematics, to see how the Kindle handles the esoteric symbols and formula that make up the language of Mathematics. (Conclusion: no problemo! :)

I've also been busy on the website using Amazon's tool for requesting books to be published for the Kindle by visiting the many book orders that I've made in the past and clicking their "Kindle Request" feature.

I firmly believe in the eminent demise of paper books as the generations that are totally devoted to paper books pass on. Everything about eBooks makes them better in my very opinionated opinion - they take up no space, they can be indexed and searched electronically, one can highlight and mark them up with notes, clip portions from and transfer them among other useful devices, and basically do anything that an ordinary book can do - ONLY BETTER! I fail to see the attachment that so many have to the old paper-based technology, but then again, I never was a Luddite - someone who resists change just to resist it. Besides, my new Kindle fits perfectly into the padded slot in my beloved Franklin Planner, so why not?

The Android Revolution is exploding! 12 Phones strong and growing in number - just like the PC revolution of the 1980's or the Linux revolution of the 1990's! This is good - very very good indeed.

Open source has always been a better choice for a number of reasons but the most important one, of course, is that it allows people - empowering individuals - to apply their own talents towards improving the system for everyone else.

Of course, mine is not an unbiased opinion, since I am a co-author of a book on the Android powered cell phone - but be that as it may, the system is growing in popularity and that is making me a very happy man. Viva 'la Android!

Fort Collins, Colorado

Here is the view from my hotel window. It's a beautiful and cool day in Fort Collins, and the HHC 2009 conference begins tomorrow at the Hewlett-Packard facilities. My mother and I made the trip okay and the only difficult part of the trip was from the Denver bus station to Fort Collins (about 53 miles) since the bus was packed with people. (Full occupancy.) The hotel (Cambria Suites) is great and the food that they served us for dinner last night and breakfast this morning was first-class indeed!

I look forward to a bit of shopping today, since I will need nicer clothes for the conference. Directly across from the hotel is a shopping mall and I should be able to find something to wear. I'm also going to eat lunch at the food court there - if they have one.

I'm in a mad rush right now to get everything that I'll need packed and ready for the trip. To borrow a Star-Trek expression, the Borg (Amtrak) are about to assimilate me and I know now that resistance is futile.

I have so much to do ... transfer my archives from the main workstation to my HP notebook computer ... make printed copies of everything to do with the trip ... pack the essentials (pills, tickets, electronics, and oh yeah - clean clothes too) ... mentally prepare to be away from my comfort zone for two weeks ... hand off any work to my partners ... and of course, try to get some sleep this evening and late night so I can be ready for the ordeal beginning at 4:00 AM tomorrow morning.

I've been working on setting up RSS/Atom feeds so that my blog can be exported to both Amazon's Author Central and Facebook. Hopefully this post will make it to both sites. It's so nice to be able to work on one site and have the content exported to others automatically. Five copies of the Web Geeks Guide to the Android-Enabled Phone were delivered to my home this morning and I was thrilled. Up until this point it was more like a vaporous entity, but as of today, it's real! :)

I'm almost finished with my packing for the trip to the HHC 2009 in Fort Collins, Colorado. The weather is so fantastic right now I almost regret leaving, but I'm sure that the trip will be worth it. I was visited by my son and daughter this morning as they were passing through. Michael was in Winfield for the weekend and Rachael was giving him a ride back to his home in South County. I am the most blessed of Fathers - I have two GREAT kids! (Who at 27 and 25 aren't quite "kids" anymore.)

It's a lovely Sunday morning in Hillsboro. The sky is clear, the temperature hovers around 60 degrees and the windows are wide open. Nothing beats breathing the fresh air of the rural countryside! Ahhh...

On Wednesday, I'll be leaving for the HP conference that I wrote about earlier and am making the trip a memorable vacation to Fort Collins, Colorado by riding the rails of Amtrak.

My mother, who loves travel and wants to see what Fort Collins is like, will be my traveling partner. She and I are very excited about the scenery that we'll enjoy and having ridden Amtrak before for short trips to Chicago and back, as well as Hermann and back, are sure that this first long trip across the Midwest will be even more rewarding. Amtrak offers some great travel bargains for travelers of all kinds (especially writers!) and I encourage everyone to consider seeing our beautiful country with an Amtrak rail pass!

Wow! I never thought that retirement would be such a busy time - but it is! Between getting my next developerWorks article finished , completing work on my first book, and preparing for the HHC 2009 conference in October, 2009, I simply haven't had much time or thought to record things here. Not that I'm complaining, mind you, I just need to relax a little and blog a little more often.

Jerri Ledford, the main author of the book I was refering to (and not the lady pictured at the left!) has informed me that writing books can be a lot of fun most of the time, but there can be times of maddening delays. We're over those delays now and the printing presses are running all-out now in order to ship copies of our book to the large book-sellers. If you have an interest in Android cell phones or Android technology in general, then feel free to visit one of the book sellers and purchase a copy of our new book, Web Geek's Guide to the Android-Enabled Phone.

A New Laptop Computer!

I purchased a new Laptop / Notebook computer today, a HP DV7-2040US computer powered by a Quad-Core processor, the Intel Core 2 Quad processor Q9000, with 4 GB of RAM and 500 GB SATA hard disk. I'm looking forward to having it delivered by next Tuesday, and plan on making it a tri-boot machine, just like my HP Workstation is. (Windows Vista, Ubuntu Linux 9.04, and my custom OS.) Since this will be my first Quad-core machine, I look forward to getting my custom OS to run on the L2 cache of all four cores, and work on inter-core communication protocols. Yes, I am very much looking forward to getting involved in the multi-core, parallel-processing arena too.

The HP-50G

I've been a HP Calculator fan since 1979 when I purchased my first HP, the HP-41C. No surprise there, eh? Well, 30 years have passed since then and the state of the art in advanced calculators is now the HP-50G. (I've actually owned mine since 2006.)

Powered by the ARM9 processor, and running at a nominal 75 MHz clock speed, this advanced, battery-powered handheld computer offers a number of features that make it very useful. It offers algebraic or RPN entry of mathematical formulas and other object types, a highly advanced computer algebra system (aka "CAS"), ARM and Saturn processor development tools, a huge equation library, and some very powerful applications like the Equation Writer and the Matrix Editor. It can be programmed in UserRPL, SystemRPL, ARM assembler, Saturn assembler, LUA, and in C with the very powerful HPGCC toolkit. I am working on adding ARM zForth to the list as well.

I'm also looking forward to attending the HHC 2009 conference on October 3rd and 4th this year in Vancouver, Washington. I hope to ride Amtrak with my good friend Tom Vogel there and back. (Tom wants to visit his daughter Dawn, who lives in nearby Seattle.)

LINUX - Stand Up and Be Counted!

I've been a Linux user since November, 1996 and am a huge fan of other Open Source software as well. No surprise there, eh? Well, here is an opportunity for Linux users to stand up and be counted. Visit this website and fill out all of the information that you can in order to join up and provide the advocates of Linux useful information on who and where we are...

Linux Counter

Linux is my preferred operating system on many of my computers - Red Hat on my work server, Ubuntu on most of my workstation machines, Android on my cell-phone, etc. As a programmer and a writer, I find that the platform is GREAT because there is so much that can be learned from studying the code that other programmers have written. I encourage anyone who wants to become a better programmer to download, install, modify, and play with the Linux source code - you'll learn a lot and have a boatload of fun doing so!

A Lovely Spring Day!

All of the Windows are open on this lovely day. The temperature in Hillsboro is 72 degrees and the winds are gusting around 20 MPH. The sky is blue and I'm loving it!

This is the first blog entry using my T-Mobile G1 as the input device. There is so much to love about this machine. It's keyboard isn't bad, but it still can't compare to the ease and comfort of the Treo 755P. That, and the camera are my only complaints about the device. With the Innocell battery, battery life is a non-issue now.

But what really impresses me about the machine's hardware is the rugged construction of it and the vast array of sensory devices built-in.

There are several distinct radios -- cellular service, bluetooth, WiFi, and GPS. The GPS is the real GPS too - not some cell-tower triangulation trickery - it actually gets its positional fix from the GPS satellites.

Throw in an accelerometer, a magnetic compass, the touch screen interface, and here is a machine with a stunning array of useful hardware. Have I forgotten anything?

Also, the fact that the device contains a SOC ("System On a Chip") with dual core ARM9 and ARM11 processors, there's some serious processing power in there! I look forward to finishing up my zForth for Android project to add some more real power into this platform that already has unlimited potential.
