End of an Era

Posted in Campfire Stories on February 15th, 2010

In the 1970′s I remember the first cable box sitting on top of our TV in San Francisco and I’ve basically had cable almost everywhere I’ve lived since then — call it 35 years of cable TV. Almost four years ago I asked Do we watch TV anymore? Analyzing our TV viewing at that time I found that of the 100 channels we only really watched four (4) channels and occasionally watched another nine for a whopping 13 channels needed.

We have (had) over 500 channels on our current service and over 100 HD channels and you know what: we never watch anything beyond 30 minutes of local news each morning. We’re paying over $170 a month and there’s nothing we bother watching.

We have a 46″ screen in the living-room that has never seen a cable connection. Kids are way ahead of old folks like me. Hulu, Boxee, YouTube, Blu Ray, DVD: these are how we watch things now. When I asked our son if it was ok to get rid of cable TV he actually asked “what’s that?”

That killed my last doubt: it’s a waste of money, we’re pulling it all out.

End of an era

The money saved in 10 months by getting rid of cable TV will buy two really nice media PCs so we’re keeping our cable-provider based internet connectivity. We’ve had 24/7 high-speed Internet in our house since 1995.

The land-line phone is probably next. Six months of saved phone bills will pay for a nice signal amplifier so our mobile phones will work great indoors.

Can you hear me now?

Update 2/21/2010 — I’m weak. I ended up cutting down to $16.95 “basic cable.”

Reduced to reblogging: a short Internet history

I loved this post by Cameron Chapman at the Six Revisions blog.

I’m reblogging ’cause I’m busy but I’ll have my media PC build and description up soon.

Teaching programming – part 2: how I tried it

Posted in Campfire Stories, The Art of Programming on June 10th, 2009

So I’m teaching a kid to program. “A kid” to me meaning anyone born after 1980 – ’cause I’m old.

Here are the choices I made.

Start with C++

If you want to be a professional programmer for the rest of your days, you should be an expert in C++. It’s all there: pointers, Object Oriented Programming, complex build issues: all the experience you’ll need.

Get a book to structure the “class”

All books suck to some extent. Just pick one and go. I chose Sams Teach Yourself C++ in One Hour a Day (6th Edition). It is big on C++ syntax, light on Computer Science topics.

Assign outside projects

I’m assigning tasks like a console Hangman game, The Game Of Life, things like that. Nothing makes concepts concrete like actually building a program that does something.

Teach Computer Science as taught at a great university

To be a professional programmer you need to be literate in computer science. Like any other self respecting astrophysicist (and therefore professional know-it-all) I tried for years to avoid it but finally gave in and learned CS.

After my student makes a pass through the Sams book above, I’ll start using the curriculum available free online at MIT’s Open Courseware. We’ll be starting with 6.00 Introduction to Computer Science and Programming

Teaching programming – part 1: how I learned

Posted in Campfire Stories, The Art of Programming on May 14th, 2009

A young person asked me recently: “Could you teach me how to write programs?”

Could I ever! I don’t know. Could I??

I’m old. I’m not so sure I’m a good example. The generations of my programming learning:

1. 1970′s — Poking around using BASIC on pre-PC microcomputers.

2. 1980′s — Writing a fair bit of software on my Timex ZX-18 using their BASIC.

3. 1980′s — Fortran 77 on PC and SunOS.

4. 1980′s — Writing a fair bit of software on PCs running DOS with Turbo Pascal.

5. late 1980′s — FTP, lots of ftp. Starting to use email. Writing Fortran apps on mini computers and using my PC as a VT-100 terminal with Kermit and a 1200 baud modem. Learned vi. Turbo C 1.0 (pre-ANSI standard).

6. 1990′s — Lots of Fortran 90 written under HP-UX and VMS. Starting to use C to interface with hardware.

7. 1990′s — CDROM based “Multimedia” projects. Silly aquarium games. Very painful under Windows 3.11.

8. 1990′s — WWW, the internet, HTML, cgi-bin scripts in Perl. Spending lots of time configuring web servers.

9. late 1990′s — The dot-com boom. All web, all the time. Microsoft ASP (classic: VBScript). Learned COM, ATL to enhance big MS technology web servers.

10. 2000′s — Big non-Microsoft web technologies. Linux, Java, Tomcat, other application servers.

11. 2000′s — Post dot-com: back to Microsoft with .NET! Love it. Back to client applications.

12. 2000′s — back to the web: ASP.NET. Love it.

13. 2000′s — set your way back machine: A huge project pulls me back to ATL/MFC/C++. Coding like it’s 1990 (Vista systems).

14. 2000′s — Computer game technology: classic C++, wicked algorithms, cool deep technology stacks like rendering pipelines, AI, terrain.

Looking back, what have I learned? A lot and especially that not all learning pain is gain.

I have growing respect for technologies that have evolved and stand the test of time. Looking down the list the Internet, client applications, and web-connected applications ebb and flow but feel like they will be around for awhile.

C++ is awesome. C#/.NET is way up there too. C# feels like C++ but someone has been in and tidied everything up. HTML has got to be one of the most ubiquitous formats on the planet.

New PC for my computer lab

Posted in Campfire Stories, Hard Stuff on May 13th, 2009

I needed an extra PC for a video editing class I was going to teach. I wanted it to be beefy enough but not too expensive. I started with a PC Gamer “medium” game system recommendations and tweaked it a bit.

Oh: it had to be quiet!

Website software

Posted in Blogs on blogs, Campfire Stories, Essential Tools on May 7th, 2009

After nearly 18 years of doing web-based work as either my primary job or in support of other work I get this question a few times a year:

We need to find a good, easy to use software program for generating the [website name here]. PC based. Any suggestions?

My snappy answer is

WordPress       WordPress at Wikipedia


I’ve used notepad, vi, VisualStudio, Netscape Gold, DreamWeaver, … All kinds of different tools. On the server side: Netscape Server, cgi-bin with perl, IIS (since NT 3.51), all sorts of pre-IIS app servers I can’t even remember the names of, Java technologies and LAMP.

I’ve used those bastard website-in-a-box things almost every ISP offers.

Way too many times.

Looking back I have to ask myself: which techniques and technologies stood up to the test of time? Which do I look back at with no regrets?

  1. WordPress on LAMP or IIS
  2. IIS/ASP and IISĀ  with ASP.NET

On the desktop editing/managing side? VisualStudio and Visual Source Safe

That’s it. I assert that you can build ANYTHING with these technologies. I routinely build sites that use BOTH 1. and 2. — like

If you are a beginner: go pure WordPress. if you need more site functionality there is almost anything you could want available as a wad of PHP you can tack on.

If you need a real web application — and you think it is going to get large: ASP.NET is astoundingly powerful and lots of standard functionality is available out of the box. Especially identification/authentication and data driven UI functions.
