STICKY POST

About me.

, ,

Don't expect frequent updates ...

First of all, the required stuff. I'm a moderator in the forums, but I'm not an Opera employee. I don't pretend to speak for the company, as a volunteer I have no authority to do so.

Okay ... what I do. I'm trained as a mathematician, and have a background in programing. That means, I specialize in analyzing problems. I also have a prodigious memory, which makes me good at my real job too (strange as that may be) - but I'll get to that. The reason they chose me to be a moderator (as I understand it anyway) was that I spend so much time in the forums trying to help people anyway, that I'm reasonably professional in the way I handle myself, and that I don't live near the European time zone (they were looking for a few people who were likely to be around when Europeans slept).

My real job has almost nothing to do with all of that though. I deliver newspapers. I can figure out the best way to deliver a particular route in short order, I can memorize even a larger route in just a few days and remember it months later, and I'm also good with people. Yeah, if you figured it out, I'm a professional substitute carrier - when they have no one else to do a route or no time to find someone, they call me. And especially if it is a "motor route" (an out of town route that requires driving), I'm the only person that my real employer has who can take any motor route on short to zero notice.

"You have a Ph.D. in Mathematics, and you deliver newpapers for a living?!!" Yeah, that's me. I'm not enough of a disciplinarian to teach professionally, I can only teach those who are self-motivated.

And if you're asking, no, I'm not bragging about any of that ... well, mostly. I was born with it, I neither take nor desire any special credit for my analytical skills, my memory, or the way I handle myself. It seems like I've always been that way. It is just how I am, it is not a matter of any special pride - indeed it has been a liability at times.

If there is anything which I feel I can take pride in, it is every time someone tells me "Thank you." In my profile I listed my occupation as "Making the world a better place," and that is what I'm all about. I know, it probably sounds "corny", but all I really care about is helping people - well, that and having food on the table. :wink:

A couple of "rules" though ... it would take away from my time and from the forums in general to answer Opera questions posted in the comments. If I post something about Opera here, of course feel free to comment on that, but if you want me to help you with some problem then post in the forums. I can't answer every Opera question anyway, in the forums someone who is better with a particular subject can answer your question if I can't. And in the forums someone will probably get back to you faster - even if that someone is me.

Don't expect me to post regular updates. Right now between the new forum software (cleaning up duplicate posts and such) and the high traffic following the release of 8.50, I don't have all that much time to devote to a blog. Of course, things will quiet down eventually, but also I'm just not the sort of person who does this regularly. I'm not about "me", or about chat, I'm about getting things done. Maybe sometimes I'll actually use this as a way of getting things done - some of the other helpful people in the forums seem to do that quite well.

On the other hand, this is a blog, I don't want to turn it into an Opera tutorial either. I'll post what I'm thinking about at the time. I hope that I'll be offering a slightly different perspective - as I said in the description for this blog. No real point in me posting the same thing as everyone else, if I don't have something to say which I think is a little bit different then I won't say it.

(Yeah, in real life I'm not much of a coversationalist. When in a group, I'll add the parts I think people may have missed - the stuff I think might be important - but I feel no need to carry the conversation or just agree with everyone else. So, in the larger scope of the Opera community here, don't expect me to chime in on every single issue that comes along. And of course, in real life it would take you several hours or even days to drag all this out of me. That's who I am.)

"False rumors" in Flag City

Well, looks like we made the front page of the Washington Post. Maybe some of you even saw it? They painted a rather ugly picture of this small town ... sadly, none of it true.

On Monday, the Washington Post ran an article about how Internet rumors are effecting Barack Obama's chances in the upcoming general election. Since they chose us as the means to present their story, the local paper picked it up yesterday and ran it on their own front page - but they also ran the real story beside it. Additionally, they had an editorial about the whole thing, and a number of letters to the editor. (Ah, the digital age, where you can receive letters from everywhere the same day ...)

I won't repeat the story. If you haven't heard it yet, you can click the various links. Both stories are a bit long of course, but you really have to read both. (And if you're asking - I did look around the Washington Post's website to try to get the story straight from them, but couldn't find any link to archived stories. I'm sure it must be there somewhere, but they sure don't make it easy to find.)

Yes, I did say "sadly" back there, the fact that they could practically make up a story like this in order to advance their agenda is well beyond "disappointing". Okay, I don't read the Post - and after this I'm certainly not going to start - but I have heard some of their stories quoted on radio and television. And while I recognized that they were basically one-sided, I still figured that they must have some amount of journalistic integrity ... apparently I was seriously mistaken.

Equally sad is that anybody believed them. We're not exactly some little hicktown, we do get cable here. We've heard all about these rumors - as much from television as anywhere else - and the real facts. Personally, it wouldn't matter to me if Obama was a muslim - in fact, I would probably be more likely to vote for him if he were, but that's me. The fact he's black, and his father was a muslim - he didn't choose either one of those, it doesn't tell me anything about his character. Like most people, I want to vote for someone I can believe in, and race, sex, religious affiliation, and age really don't mean anything. (Not that I'm claiming most people in town are like me - that would be really boring - but we're not living in the stone age here.)

Worst of all is those people who not only believed the story, but somehow believed they could do something about it. I'm sure that by now all of those people mentioned on College Street who didn't already have an unlisted phone number have changed that. And those letter from Columbus and from Washington? Completely incredible.

So here you have a liberal, big-city paper telling their readers pretty much what they want to believe - is there no critical thinking left in this country?

I guess I'll never understand politics. There's two groups of people - no, not the Democrats and the Republicans, but the true believers and the rest of us. The "party faithful" their called, they believe what they want to believe, and think they can win everyone else over based solely on the strength of their convictions. And then of course, anyone who doesn't agree with them is short-sighted or downright neanderthal. Well, sorry, some of us need more.

Then again, there's a lot of people locally who were "on the fence" who would now have made up their mind. Yes, that's right, thanks to the Washington Post the odds of people in Flag City, USA voting for Barack Obama have gone down substantially. With friends like the Washington Post, who needs enemies?

(I know some of you are saying "Okay Steve, so after those nice words earlier, you're voting for McCain because of some hatchet job by the Washington Post not even related to Obama as a person." Wrong, on both counts. I made up my mind some time ago, this has no impact on how I'm going to vote. You see, I'm a Libertarian, I'm voting for Bob Barr, but he's not going to win locally either - short of some miracle.)

In all honesty ...

I'm afraid this one is going to hurt. If you're looking for something to cheer you up, look elsewhere.

I don't really talk about my life that much. Well, it's not much of a life anyway - I mean, a guy with a Ph.D. in math who delivers newspapers for a living. Or did anyway ...

I actually lost that job almost a year ago. I've still been helping some other people deliver papers from time to time, but - well, things have been real quiet of late.

I really loved that job, even though part of me knew all along that it wouldn't last. In my case you could take that literally ... I've used the term before but it doesn't come up very often, I'm what's called schizoid. People talk about "professional detachment", in my case I'm so detached that usually I don't even know how I feel. There are exceptions of course - and losing that job was one of them.

When I say "part of me knew ... it wouldn't last" you may be wondering why. No, not magic, also not part of me working to sabotage my chances (or at least, not that I know of) - in this case it was simple mathematics. It is a very demanding job, especially the schedule. I'd been let go once before for having a couple of accidents in company vehicles, fatigue and inattention will do that to you, so I knew that as long as my responsibilities remained the same it was bound to happen again. They accommodated me as best they could, but it was only a matter of time ...

But really I'm getting away from my story. Another part of my personality is that I really need to feel needed - and that's why I loved that job so much, they regularly told me how much they needed me. And when it finally happened they really went to bat for me - but the problem there is the insurance company, not my actual employer.

So anyway ... well, I just couldn't deal with it. I just shut down. The only thing that kept me going was my online friends and my responsibilities here, even though I never discussed it.

Believe me, it isn't easy being unemployed and depressed. It helped that I was living in my parents' basement, but I provided all my own food all that time - and helping people out on their paper routes doesn't pay much let me tell you. So what's changed? Well ... obviously Dad thinks of me as a freeloader, I was supposed to be paying rent and such, so now he's planning to kick me out.

Don't take this wrong, he really is a great guy and all. But we never really talk. Not that I'm very good at talking anyway, I can handle "small talk" in any crowd but when we're done you really won't know anything more about me as a person. But you know, taking to Dad is about like talking to a brick wall. And sometimes he says the stupidest things - things you know aren't true but he sounds like he believes them. And even if I were one to try to argue with him, it wouldn't do any good. Add to that the fact that when I was working we never saw each other just due to the scheduling.

Dad says that I really need to get a job, which is true of course but it's not that easy. I need to talk with someone, to get some understanding and emotional support so that I don't have to face everything by myself ... if things were different maybe he could have done that, but I wonder if it's a hopeless cause at this point.

The other day he asked me if I'd made any plans for what I was going to do. I'm sure he doesn't realize that I answered his question when I made a comment about needing to feel useful ... the fact of the matter is I can't plan. If he kicks me out, then I have no emotional support at all because I won't be able to keep in touch with you guys or my other online friends. For someone like me - unemployed, depressed, homeless and with no emotional support ... I'll probably just curl up under a bridge somewhere and die.

I cried that night realizing he didn't understand my answer, something which doesn't happen very often when you're as detached as I am. And of course I'm going to cry again having to discuss it just now. :cry:

Sorry to end on such a down note, but that's what I'm dealing with. If I disappear from the forums in a couple of weeks, you know what happened. And yeah, I'm crying as much for him as for me. I do have a conscience, even in this state, and I know if he actually does follow through on his plan it'll just kill him.

After the flood ...

(See photo album of the same name.)

It's been quite a year for residents of Findlay, Ohio, and not in a good way. The newspaper and radio say that we've had 10 official floods in the last 15 months (as in, since the start of 2007), and 5 in just the last 3 months, including 2 in the last week (one last Saturday from melting snow, and one yesterday from the torrential rains flooding the central US this week). Not that flooding is unusual in this area, but this has been excessive - two of those ten floods are among the ten worst on record for this area. The one last August is the second-worst flood recorded here, and one last month is fifth (see table on this page of "record crests").

I did mention "melting snow", we've also had a couple of blizzards and strangely enough are expecting more snow tonight. :rolleyes:

But back to the subject at hand ... I guess it is understandable then that Noah's Ark features prominently in this year's annual Easter sand sculpture in Riverside Park. Never heard of it? We get tourists here every year who've read the book and come to see if it's real ... Yes, it is real, though other than the crucifix the details vary from year to year. (No, I haven't read the book, given that it's listed as "inspirational fiction" one must presume that the other events and characters described there are not all real ...)

What can I say, really? This year's sculpture reflects the hopes and yearnings of the entire town. Some people are ready to give up, for some reason they figure that after 150 years or so we should just let the river have the town back - okay, I can understand a certain amount of desperation after what we've been through, but in principle at least none of us should be alive the next time we have a year like this.

(For those interested, the local newspaper has up a stream of an interview with the artist, Roger Powell. It is an mms link, it should open in Windows Media Player. If you don't use Windows, try MPlayer or VLC.)

2008 - the year of Linux?

I've been observing somewhat more than the usual number of articles saying that 2008 will be the year of Linux. I say it that way because ... well, I've seen articles with that topic since 2000 at least. And obviously all the previous predictions have been wrong. What's so different about 2008?

Well, there are some differences. An article on Information Week brings up a couple of them. No, actually, Wal-mart selling a Linux PC is not new, they've sold PCs by Everex with Mandriva on them, with Linspire, ... and now with gOS. What is gOS anyway? Answer - it's actually an alpha version of a system based on Ubuntu, using Enlightenment as a desktop manager, and including a large selection of Google-based apps. Let's face it, Enlightnemment is neat though DR17 is still in heavy development, and Google and Ubuntu both have a high buzz factor. But do you think anyone actually bought the Everex gPC from Walmart because it had gOS on it? Yet before Christmas, Wal-mart was having trouble keeping them in stock.

You could say that Linux had arived last year, when Dell started to sell computers with Ubuntu Linux preinstalled. Not that Mr. John Q. Public was going to pick one of those Dell Linux PCs over a comparably priced Windows system ... Windows is familar and hence safe (in spite of the frequent security issues and stuff), as long as you're getting two comparably equipped systems - one with Linux and one Windows - for about the same price, most people will take Windows.

So what happened with that Linux PC that they couldn't keep in stock at Wal-mart? Actually, it's pretty simple. You can run Linux quite decently on a system with a 1.5 MHz Celeron-class processor and 512 MB RAM and it'll look as good as Vista running on a quad-core system at twice the speed and with twice as much RAM. In fact, Vista will only barely run on a system with 512 MB RAM. That's the real story here, the Everex gPC was only half the computer (theoretically) of even a low-end Vista PC, but even with an alpha version of a Linux distro would put that same low-end Vista PC to shame on performance, and at half the price.

Okay, it's not going to be able to play the latest fully-rendered video game. Neither would that low-end Vista PC, so that's really besides the point. But it will browse the internet in Firefox (or Opera of course) as well as that Vista PC, it'll balance your checkbook as well as that Vista PC, it'll let you write your great American novel (or maybe that's great Croat novel) as well as that Vista PC would - in short, it'll do everything that your typical household would want to use a computer for just as well as the Vista PC. And without worrying about computer viruses and so on ...

That's the real story here. Not that Vista is such a poor OS - in a few senses at least it is not - but that it is so demanding you really need a high-end computer to use it.

Last year was a great year for Apple. If someone is looking for an established computer OS which is safer than Windows and without the performance issues, you know where they'll go, so I expect Apple to continue to do well. But somewhere along the line Apple Macintosh stopped being "The computer for the rest of us" (that was their advertising slogan at one time). I mean, sure you'd like to be able to afford a $1000 computer for you kids to do their homework on - but if you had that sort of money I'm sure you could think of 100 other things that you need even more.

Okay, the OLPC XO didn't turn out to be the $100 laptop it was originally planned to be. That doesn't make it a failure. Lots of people can use a $200 computer - just ask Wal-mart.

The year of Linux? Let's hear it for the year of the bargain computer!

Fame

There are a couple of songs running through my head of late, one is called "Fame" and part of the chorus goes as follows:

Fame -
I'm gonna make it to Heaven,
Light up the sky like a flame.
I'm gonna live forever
Baby remember my name

(For the record, the other song is the theme from Cheers - I'll get to that.)

If you believe what you see on television, then everyone feels like that. Okay, maybe not the throngs of autograph seekers and paparazzi, but wouldn't it be nice to be recognized everywhere you go - in a good way of course?

To tell you the truth, I'm not so sure...

First of all, let me say that I'm terrible at names. If I met you somewhere and we were introduced, I'd have forgotten your name within about 2 minutes. I'd remember whatever else was said during the intro, who you worked for or which friend of a friend we both knew, but I just can't connect names to faces. So it isn't unusual for me to run into someone whom I'm sure I know but I have no idea what their name is. You get used to it ... :whistle:

Recently though I've been running into people whom I have no idea of ever meeting who address me by first name. I was at the store last week, as I was getting ready to go out to my car the cashier said "Have a nice evening Steve!" Okay, some of them are trained to read names off of credit cards or ID to be friendly - but I paid in cash and wasn't asked for ID. (Even though she should have asked as I was buying some pistol ammo ...)

Then a couple of days later, at the mall I run into a guy I used to work with who goes by "Reggie". That's fine, I knew who he was and all, but then a couple of minutes later I pass by the mall's Santa Claus and he wishes me "Merry Christmas Steve!" :psmurf:

If I had some idea why these people knew me, that would be one thing. But someone I wouldn't know from Adam ... really, it's disconcerting :left: :right:

The theme from "Cheers"? That was called "Where everyone knows your name", of course.

Hacking MyOpera

When I first joined MyOpera - 5 years ago - the forums would let you enter anything at all for your location. When they initially went to the new "community", you could still enter anything at all - and if you left it blank then they listed "Atlantis" as your location. :whistle: At some point though, they changed it to a dropdown box that says "Country" and you choose from the list ...

Other than myself anyway, if you see someone on the forums with an unusual location, that means they haven't changed it in the last year or so. Thus ... well, like bluesman2333 where his location says "in a pot of thick marinara", for example. (That was a joke about his avatar, if you must know.)

But besides that, maybe you just live in a location that didn't make their list. I don't see Easter Island, I'm sure there must be other places which aren't on the list. Maybe you're posting from Antarctica penguin or Betelgeuse :alien: ...

Or maybe you just want to fix your time zone. :rolleyes: While I'll only describe location, this technique can probably be used on time zone, forum posts per page or other such settings. I've managed to help some people to revert to the old blog designs too.

Anyway, say that bluesman2333 is tired of that pot of thick marinara and wants to change his location to Easter Island. (Not that he really lives there, but it would go with his rabbit avatar. :D) He would click on "My account" at the top of the page, then on Edit my profile, and finally on View > Source. Okay, that looks like a complete mess, but not unintelligible.

If you scroll down a bit (or use Ctrl-F Find) you can find the following:

<p><label for="location">Country:</label>
<select name="location" id="location">
 <option value="">---</option>
 <option value="Afghanistan">Afghanistan</option>
 <option value="Albania">Albania</option>
 <option value="Algeria">Algeria</option>
 ...

(Yes, I have tidied that up.)

Pick somewhere that you can find it - either right below the top or else where it would be listed alphabetically - to add your option. Taking the first choice as easiest, he'd add the code for his desired option as follows:

<p><label for="location">Country:</label>
<select name="location" id="location">
 <option value="">---</option>
 <option value="Easter Island">Easter Island</option>
 <option value="Afghanistan">Afghanistan</option>
 <option value="Albania">Albania</option>
 <option value="Algeria">Algeria</option>
 ...

(No, he doesn't have to tidy it up. Just so long as it's a complete option tag and doesn't appear in the middle of another tag.)

Then he clicks on "Apply changes" (up in the toolbar) and switches back to the actual page. The "Country" dropdown now looks like this:

He just selects his option from the dropdown, then scrolls to the bottom and clicks on Save profile, and there it is.

For people who are wondering how this stuff works - the website cares about the value="Easter Island" part of the tag, the rest of it is to make sure it looks correct when you are choosing it.

Telling the truth

Today is Blog Advocacy Day, and the official topic is the environment. Between that and last Friday's awarding of the Nobel peace prize to Al Gore, I imagine more than a few articles will be about "global warming" ...

I don't know, too many people who are behind this issue seem to have their own agenda. It is a fact that we are warmer now than we've been in years. But the truth is, all the global warming advocates have to admit we are actually warmer than they expected, and they can't explain it.

A lot of people wanted to blame hurricane Katrina on global warming ... but as hurricanes go Katrina wasn't even all that noteworthy. It was unfortunate the way that it struck New Orleans and all, but when it made landfall it was only a category 3 - we've had much worse hit this country before.

Don't get me wrong, I'm all for saving the world, but let's be real. I think global warming is probably a real phenomenon, and yes Al Gore does deserve some small credit for keeping the issue in the public attention. But this is the guy who claimed to have invented the Internet, and as such he is too easy to discount. Likewise all the other alarmist who go around blaming Katrina and whatever else on global warming, when the real scientists say "No".

The truth is, no one really knows what to do about global warming at this point. The first step would seem to be to conserve - which with energy prices these days is a good idea regardless. Walk to school or work on nice days, though if you're on a bus route you might as well take the bus. (The bus will still have to run whether or not you ride it, so you aren't saving anything by not riding it.) Use energy efficient appliances and lights, and turn off lights when you don't need them. These newer compact fluorescent bulbs use about 1/4 of the power of incandescent bulbs for the same amount of light and they last longer too. But conserving energy is only a start...

If you really want to stop global warming, then you also need to remove carbon from the atmosphere, not just stop adding it so quickly. That means green plants. Planting trees along the south side of your house can reduce your heating bills, but the trees also help remove carbon from the atmosphere.

Most of all, think realistically. Many people who live in big cities don't have yards and so can't plant trees. When possible, don't run the heater or air conditioner. Okay, if it's 95F (35C) outside then you don't have too much choice, but you produce more heat outside than you do cooling inside - cooling especially is a losing proposition. If possible, cool a smaller area - maybe only a few rooms. And don't set the thermostat too low for the same reason, about 75 to 80F (about 25C) is fine. When it is cold out, set your thermostat cooler - they normally suggest 68F (20C).

People really won't listen to you if you exaggerate or otherwise say things that aren't true though. Don't blame the temperature on a given day on global warming, people generally know that isn't true and will stop listening to you when you try to tell them what to do about it. Let's face it, the reality is bad enough, you don't have to make it any worse.

5 things I'd like to see in Opera

, ,

I've been tagged by Tamil, let me see if I can get together a list. If I can remember them all, these will be things I've posted before in the forums ...

1. Remove attachments from email messages
2. A button editor
3. The ability to perform gestures over images, as we could in Opera 7.0
4. PGP/GPG and similar features for mail
5. Compressed web archives, and compressed mail storage.

As you can see, a couple of these go way back ...

Yes, in Opera 7.0 you could assigna gesture to Save image and it would act on the image you started the gesture over. For some reason, this feature simply disappeared in 7.10.

Back before most email providers had virus filters, I wanted the ability to remove an infected attachment from a message without actually removing the message. But I can also see that you might want to save an attachment to disk so you can view it - but if you've saved it, why do you still need it in the message?

I'd like a simple dialog that you could get when you right-click on a UI button so that you could edit that button. Obviously, it would be nice if you could graphically choose the button icon, but even something that's strictly text would be okay. Of course, the same button could be used to create a new button.

I don't think that PGP/GPG support really needs any explanation, but I'll say the obvious anyway: If someone sends you a message with a detached PGP signature, you should be able to verify the signature without having to copy the raw message and paste it into a file.

And finally ... HTML and email both take lots of memory. Many web servers will transmit web pages compressed (seems like UNIX z compression is the default) for just this reason. When you save a page - especially as a web archive - you should be able to save it compressed. And of course, Opera should read the file without some third-party unarchiver. Same applies to email storage, but more so since most people have lots more stored email then stored web pages.


I'm supposed to tag "up to 5" people ... I haven't made up my mind yet, but I'll find someone (and say who in a comment so you can see what they post).


Addendum: they tell me - now - that rules for this game require I list the people in my blog post. :rolleyes:

Okay, I tagged philry4n, fammcdon, Sanguinemoon, and sebt.

Technology

As a former Math teacher, I'm always interersted in calculators. I have ... well, must be 25-30 of them, though a few no longer work.

I remember when the HP-41C was considered "top of the line". It really wasn't all that special in today's terms, it had memory for up to 63 numbers, though some of that memory could be converted to usage for programs. In real terms, that comes out to 441 bytes. Today your typical scientific calculator can do most of what that could ... and of course at a fraction of the price.

In fact, that's what prompted this. I have just found a calculator which has some features I've previously only seen in models costing $100 (US), and this one costs $18.

I can't show "proper" math here, the forum doesn't support MATHML or something similar, but this calculator can do that to a certain degree. It can write fractions and square roots and exponents (okay, I can do exponents here), and it can display its answers with fractions and square roots in them. Okay, something like the TI-89 or the HP-48G can do some things this won't - but those both cost over $100. And this will fit in your pocket.

By now you're asking "Okay, but what is it?" It's a Casio fx-115ES. Actually, I have a hard time saying that, back when I was teaching the Casio models were somewhat behind the similar Sharp and TI models, to me this is like a "quantum leap" over what they were then - and over the competition.

But ... there's something to be said for the old ways too. When this calculator is set to "MathIO" mode, you have to use the cursor keys to make sure everything is in the right context. You can't just type "SQRT 3 / 4" (where SQRT represents the square root key) because it isn't clear whether the editor should put the division sign inside the square root or outside. I'm familiar with that sort of system from my more expensive calculators (and some computer programs), your typical high school kid will probably be completely lost. Well, for a while anyway.

A conscession to the old ways then - yes, you can set this into standard "LinearIO" mode, but if you do then it displays answers like any of the other calculators. When you're in MathIO mode, you can enter something like "SQRT 8" and it will display an answer of 2 SQRT 2. It can simplify square roots and rationalize denominators (as long as the numbers aren't too large), in LinearIO mode you'll just get the decimal 2.828427...

Of course, to be able to display stuff like that you need a graphical display, it looks to me like the display here is 100x31 pixels. But though it has a graphical display, it does not graph formulas.

This model can also do integration and derivatives (numerically, of course) and has an equation solver, though the prior version also had that. Other new features include an actual table editor for statistical data (though the table is limited to a total of 80 values), and vector and matrix calculations (up to 3x3).

Would I recommend it? I don't know. If you're an engineer or some other professional, you probably need one of those $100+ models. If you're a high school student, it may be too hard to learn - at first anyway. If you're a college student studying to be an engineer, well then you need what an enginner needs. Though then again, there may be times when that $100 calculator is just too big, and you need something handier. So I'm not going to say no, but it shouldn't be your primary calculator. Oh, and I suppose that high school student could put it into LinearIO mode and use it as if it were a standard 2-line calculator, until he or she does get the hang of MathIO mode. If you're going to be working with vectors and matrices, then it would still be worthwhile.

But I'm still amazed by it. I know technology has progressed a lot since I taught math (10 years ago), but other than the 2-line display and the "multiline replay", there really haven't been many changes in the low end scientific calculators.

I wonder what they'll look like 10 years from now?
