BIOS & Conclusion: Multiple Causes

Welcome to Comcast browser greeting

unwelcome Welcome to Comcast (click image)

This concludes the saga of “BIOS Won’t Boot“, a most unfortunate sequence of events occurring on April 1 (yes). The story was posted here April 8.

On April 11, Sunday afternoon, the second day of my return from Phoenix, you couldn’t tell there had ever been any issue(s) on my Castro Valley machines, and I didn’t have to spend a nickel to replace any hardware, either. It’s always nice to have the spare 3V CR2032 BIOS battery I bought for this occasion in Phoenix, wouldn’t you think? But I didn’t need to use it.

BIOS Won’t Boot!

I’m in Phoenix at the moment, returning to the Bay Area tomorrow. I’m staring at my newly rebuilt Windows 7-64 PC, which is working great. It’s dawning on me that when I shut it down tonight I won’t need to say good-bye. Taxes are due in a week and my PC up north died.

I’ll be packing the car tonight for the drive north. In addition to the usual travel stuff,  I’m packing (1) a CR2032 3V Lithium CMOS battery, and (2) this PC. I just lugged this PC down here to Phoenix last month. Since I’m moving here soon anyway, lugging the PC back north with me just seems counter-intuitive.

Yes, I also have a fast Mac Pro up north, but all my tax stuff is on the PC.

Usually, when I post one of these “this happened to me” articles, there’s a moral to the story. In this case, I don’t know what it is yet. The PC failed just when I had to get a night’s rest for an early morning drive south. If I had to guess what the moral of the story will turn out to be, NOT forcing Windows shutdown with the Power Button would be high on my list!

Here’s the story (or what I know of it so far), excerpted from a letter to a friend. There’ll be a follow-up post once I do the diagnostics and fix the problem with whatever it takes.

I have a new Windows7-64 up north too, and I love it, but I may have to do all that over again too, if not very lucky, as soon as I get back next Friday.

Less than 12 hours before I had to leave for Phoenix, I was on the phone with Comcast cable/internet to get them to reset my new modem again. Some browser intercept feature of theirs was hijacking my browser on all 3 CA machines – a Mac and two PC’s.

Their tech guy reset the modem, got customer service to update something or other that should make the “hijack” screen go away, and he had me shut down and reboot the machines. This fixed the problem in the Mac and the old XP machine. The Win-7 machine refused to shut down. After several minutes, I forced it off with the 5-second Power Button trick. I don’t like to do that, and normally don’t.

Why Doesn’t Stuff Just Work As It Should?

Steve Fox of PCWorld raised some timely questions in his March 2010 column Tech Products: Revolting not Not Rebelling :

… our state-of-the-art technology too often fails to work as it should. That’s why I have to reboot my Wi-Fi router at least once a week; why my fingerprint-recognition pad periodically forgets what my thumb looks like; and why my smartphone keeps dropping calls without provocation.

Mostly, I think the answer likes in our neglected software development process. In darker moments, many of us probably suspect that our software vendors hire besotted programmers to code their operating systems and mission-critical software in bars and back alleys. In truth, a coding project like a modern Mac-OS-X or Windows 7 may rival the Manhattan Project in resources and organizational complexity. When things go south, where did we go wrong?

Smiley Madness

It sounded so simple. Wouldn’t it be fun to add smiley recognition to my own little web programs? WordPress does it automatically. They just can’t decide whether it’s spelled “smilie” or “smiley” – depends who did their coding.

Well, after all, every time you see the symbols “:-)” , you’d just replace the symbols with the image path to the appropriate smiley, wouldn’t you :-) ?

So you can see the manual smiley markups, I even had to enclose the symbols in quotes for this post, to prevent WordPress from converting them to their image equivalents.

Outside of WordPress, it turned out not to be so simple. You see, every symbol in the smiley “grin” markup is also a “special character” in Perl and most other programming languages. The coding to test for their presence will therefore match to symbols which, themselves, are program control characters. So the program thinks it sees a syntax error and blows up.

Mac & Windows Notes

I continue to enjoy my Mac Pro (under Snow Leopard) and my PC (with newly installed Windows 7-64). Following are some collected notes & observations.

  • Music: for years I’ve been careful to select PC motherboards with the best onboard sound processors (DAC’s). I knew I would be interested in finding the results of A/B sound comparisons between Mac and PC playing the same iTunes tracks in synch.
  • iTunes: “PC music” is a hot topic in the high-end audio magazines these days. The thinking is that you have to get an external DAC to wring true “hi-fi” stereo sound out of your PC – and the pros are often as not using iTunes to create their own state of the art music servers – something I’ve been doing for years, using just the onboard digital-to-analog logic.
  • And the audio quality winner is: Continue reading

Windows 7 Impressions

I won’t pretend there was any urgent reason to upgrade from XP to Win 7. My XP installation was getting slower and slower, and that was only just reinstalled in July. My new Mac Pro (64 bit Snow Leopard) greatly increased my dissatisfaction with the PC side: if I’m going to live with Windows, and I am, I needed to do something!

A new motherboard and chip was financially out of the question. I’m running an ASUS M2N-SLI Deluxe with AMD 64 6000+ CPU. It’s not that old. By the time you add all the other stuff you always find you need, a slight upgrade turns into a major investment. I decided to go full bore with 8GB RAM, Windows 7 Pro (64-bit), and a better graphics card that would support “Windows Aero”.

WordPress server on Mac localhost

First test WordPress installation on local Mac machine. Click image for 1024x768 view.

First test WordPress installation on local Mac machine. Click image for 1024x768 view.

Pictured above is a test WordPress installation running on a desktop Mac. It’s running under a free development environment for Mac called MAMP.  No internet connection or remote server uploads are involved at all.

WordPress is the popular free web blog engine that evolved into an excellent website platform. If the page pictured above looks familiar, that’s because Summitlake.com (and thousands of other sites) are running under WordPress. Continue reading

Use Wireless Router as “Repeater” Station

I had seen mention on the internet that it was possible to use a wireless router on your home network without replacing the existing wired router-firewall and CAT5 installation. Most of my machines are already wired into my “blue cable” ethernet LAN (which is much faster).

Unlike an earlier experiment a few years back, this router had excellent range. It’s an ASUS WL-520GU broad range wireless router I picked up on the cheap on a whim at a NewEgg sale, but I never spent the time to try to work through the setup. Continue reading
