In 1986, I purchased a Hewlett-Packard HP-15C scientific programmable calculator, for $120 or so. That was a lot of money back then, specially for a penniless high school student, but worth every penny. I lived in France at the time, and HP calculators cost roughly double the price there, so I waited for a vacation visit to my aunt in Los Angeles to get it. HP calculators are professional tools for engineers and you couldn’t find them at the local department store like TI trash, so I asked my aunt to mail order it for me prior to my visit. I still remember the excitement at finally getting it and putting it through its paces.

The HP-15C is long discontinued but I still keep mine as a prized heirloom, even though I have owned far more capable HPs over time (the HP-28C, HP-48SX, HP-200LX and more recently HP-35S and HP-33S) and given most of these away. The HP-15C’s financial cousin, the HP-12C is still in production today and has a tremendous cult following.

The reason for the HP Voyager series’ lasting power is many-fold:

• Reverse Polish Notation (RPN), HP’s distinctive way of entering calculations. For instance, to calculate the area of a 2m radius circle, you would type 2 x² π x instead of the more common algebraic (AOS) notation on TI or Casio calculators π x 2 x² =. With practice, RPN is much more natural and efficient than algebraic notation. When I went from high school to college, the number of RPN users went from 2 (myself and a classmate who owned a HP-11C) to over 50%.
• The ergonomics of the calculators are top-notch, from the landscape orientation to the inimitable HP keyboards with their firm and positive response.
• They offered far superior functionality, like the HP-15C’s built-in integrator, equation solver, matrix and complex algebra, or the HP-12C’s financial equation solver.

The HP-15C offers the right balance of power and usability. The HP-48SX was far more powerful, but if you stopped using it for more than a couple months, you would completely forget how to use it. The more advanced functionality like symbolic integration is better performed on a Mac or PC using Mathematica or the like, in any case.

Unfortunately, Carly Fiorina gutted the HP calculator department in one of the more egregious of her blunders during her disastrous tenure as CEO of HP, outsourcing R&D and manufacturing from Corvallis, Oregon to China. HP has been trying to regain lost ground, but it is an uphill battle as TI has had ample time to entrench itself.

All this long exposition leads to the news HP has released an app (and for other models like the HP-12C)

I benchmarked it by integrating the normal distribution (f LBL A x² CHS e^x 2 ENTER π x √x / RTN) between -3 and +3. On the original HP-15C, this takes about 34 seconds. On the iPhone emulator, it is near instantaneous. On the nonpareil emulator running on my octo-core Mac Pro, it’s more like a minute…

Update (2012-07-13):

Sadly, it closed a few months ago.

My old apartment had a flag in its back yard, apparently the flag pole and bench was a memorial for a Marine killed in combat. After September 11, when all flags were supposed to be struck in mourning, that one flag hadn’t been lowered, so I went and drew it down to half-mast, with proper honors. You would think there would be at least one US citizen around who would care enough so a French one did not have to…

The flag seems to crystallize a lot of posturing on both sides of the political spectrum in the US, but people are woefully ignorant of proper flag code. It prohibits wearing the flag as apparel, for instance (except for duly authorized personnel like the military), or its use for advertising purposes (the biggest flags around seem to be those on car dealerships). Burning is also the recommended form of disposal for a worn flag (respectfully, of course).

The content producers’ lobby is very ancient and powerful in France (it was started by the playwright Beaumarchais in the 18th century). The fact President Sarkozy’s wife is an important rights holder may have something to do with his determination to pass the abject Hadopi law, which would cause Internet users caught illegally downloading content to be cut off from the Internet (while still having to pay their ISP fees).

The law was exceedingly stacked towards the content industry. The burden of proof was on the defendant rather than the prosecution, and an extra-judicial quango named Hadopi was to be set up to enforce these sanctions. The European Parliament, to its credit, had opposed such measures and restated that Internet access is a fundamental right that can only be curtailed by proper judicial authority. The first reading of the law led to a surprise defeat, as the majority UMP legislators were unenthusiastic about supporting a law that would alienate the young, and absenteeism was such that the minority Socialist party managed to overwhelm those few present. This is one of the exceedingly few times I actually agree with the feckless Socialists… The President brought his whip to bear and the law was put back on the agenda and voted in the second time.

Today, the Conseil Constitutionnel ruled on a challenge to the law put by Socialist parliamentarians, and gutted it in line with the European Parliament. In doing so, it affirmed that Internet access is a fundamental human right, drawing all the way back to the original Human Rights declaration of 1789, and that Internet users are innocent until proven guilty.

This is an important decision. In Roman law, judges’ discretion is much more limited than in the Anglo-Saxon Common law tradition. The US Supreme Court found in Roe vs. Wade a right to abortion in the US Constitution that is far from obvious, and such a decision by unelected judges lacked universal legitimacy. In contrast, abortion was legalized by an act of Parliament in France, which is why opposition to it is nowhere near as bitter as in the US. The Conseil Constitutionnel does not invent constitutional principles, it only censures laws or more commonly individual articles (the role of ultimate court of appeals belongs to another institution, the Cour de Cassation). The significance of it finding Internet access a fundamental right cannot be overstated.

I still run Solaris 10 (update 6) on my home server, but this might be the release that makes me jump to OpenSolaris, at least at home (Oracle 10g wouldn’t run on 2008.05 last time I tried at work). A few things I noticed:

• xterm-color is finally recognized as a valid terminal type
• It supports Apple’s Bonjour autoconf out of the box, which is helpful in dhcp-only environments
