tygorius··on Teaching programming languages: a novel approach
Sorry I wasn't clear. I wasn't trying to pass anything off. Someone posted a link to paper - I read it and wasn't impressed with the reasoning. (And less than impressed with the over-reaching metaphors.)

I do disagree with the author's apparent contention that, say, a historical appreciation of the evolving nature of programming paradigms is somehow holding students back today. Aside from argument by assertion, I'm missing the evidence that his approach is the solution to a problem.

What I was also missing, and am still unenlightened about after your response, is the relevance of his classroom approach to say, the readers here. It seems nearly monthly we have a story related to the virtues of SICP and that I get -- it's a great book that's changed a lot of programmer's perception of what programming is about. In this case, I'm missing a similar connection outside the classroom.

tygorius··on Teaching programming languages: a novel approach
I've read the paper, but I still find the grand metaphors like "Post-Linnaean" a bit of a reach. If you want to say that we've reached a point where few languages are pure in their approach (functional, object-oriented, etc), fine. If you want to say modern languages don't pay much a penalty for garbage collection, also fine. I just don't see the evidence that the approach hinted at has relevance to any context outside of Shriram Krishnamurthi's classroom at Brown University. It seems that most of his points that have practical application will be really old news to the programmer part of the HN readership, and have no practical value for those who aren't.
tygorius··on Storm Clouds: Gmail Failure Reinforces Danger Of Becoming Too Cloud-Dependent
Am I the only one who thinks it's nuts to describe streaming video or music as "using the cloud"? Doug Engelbart demonstrated video conferencing back in 1968, was that using the cloud as well? Sheesh.
tygorius··on Republicans: No compromise possible on net neutrality
When FairPoint doesn't perform its obligations under contract, that's presumably something for the New Hampshire authorities to pursue, as they were the other party in the contract. How is that a federal responsibility?

since we're not a desirable market, there's no chance of getting any other companies to deploy to those areas

Again, is that really a problem the FCC should address? It seems you're extending the idea of net neutrality from regulating existing networks to guaranteeing network access for all.

Interesting. The only Microsoft USB plug I have these days is one of the wireless stubs, where the logo is the only clue. I have noticed that some Logitech products have a concave top, presumably for the same tactile feedback approach.

Of course, you can always just look at the end of the plug and orient it so the white plastic key is on the bottom, but where's the fun in that?

tygorius··on Thunderbolt
Oh, that's just Crazy Bob talking. If that had really been Apple's strategy, they wouldn't have alienated so many customers in the way they killed the xServe line last year. If they had really wanted to keep their toe-hold in that market, they wouldn't have said, "Let them eat mini Macs." I think it's simply the case that Apple's signature advantages in the consumer space don't translate into a 1U world, and they recognized that.
tygorius··on Thunderbolt
Oh, it's not so bad once you take advertising sub-clause of the spec into account. That's the hidden clause that states the USB logo will be on the top of a properly-oriented plug unless you're Microsoft or Logitech, in which case your corporate name is allowed top-billing, so to speak.

Of course, if the slots are oriented vertically...

tygorius··on An Open Letter to Apple on the Readability App rejection
Changing the rules once you have a large installed base is always a delicate issue. How many current iPad owners knew their Kindle app (and others) might be deactivated by Apple in a couple of months because Apple decided it wanted a 30% cut?
tygorius··on Nokia culture will out
a very short time at a company

Well, the author says it was two years, which doesn't seem like a short time at a company these days. And part of it was in 2007. I'd say he was well situated to understand things like the company's usability blind spots and why it couldn't really understand the thinking that went into the iPhone.

tygorius··on Platform sunk (cost): What is the value of a quarter billion Symbian users?
Yep, brand name recognition and usage is not at all the same thing as brand name loyalty. As mentioned in a previous thread, Nokia's market share has been dropping at the same time as the absolute size of the market has been growing. Somehow I doubt there are a lot of Nokia users who look at an iPhone and think, "Too bad. If only it ran Symbian OS ..."
tygorius··on Forth vs Lisp
Interesting that in the previous Lisp vs Python discussion [1], the original article noted that (f x) could mean a lot of things, to which at least one comment retorted that in real code you always have a context, so there really isn't any ambiguity. Yet in this discussion there's a Lisper arguing that with A B C in Forth, you have no idea how many items have been left on the stack. (I presume this is based on a lack of experience, as Canonical Forth style suggests each word starts with a comment detailing beginning and ending stack states.) I find myself wondering, A B C would be surrounded by contextual code, so in real code the meaning would be clear, no?

I think that sociologically Lisp and Forth users are more alike than not, but the camps rarely seem talk to each other. It's clear from Forth's history that it has a secure niche in 8- & 16-bit microcontroller applications. I have no idea if there is such a thing as a Lisp application niche these days.

tygorius··on Nokia culture will out
Nokia’s problem is not, and has never been, that it lacks for creative, thoughtful, talented people, or the resources to turn their ideas into shipping product. It’s that the company is fundamentally, and has _always_ been, organized to trade in commodities.

Amen. How else to explain the continual production of a bewildering array of handsets that differ in only slight ways or in bizarre configurations. (On the latter, I'm thinking in particular of those handsets where they arranged the dialing keypad in a circle reminiscent of the old land-line phones. How in the world did those ever get into production?)

tygorius··on How to become Batman
Vigilantism is frowned on

Frank Miller directly addressed that point in "The Dark Knight" comic series. At one point Superman is remembering a past argument with Batman, and (semi-quote from memory):

"And then you laughed that scary laugh of yours. 'Of course we're criminals', you said. 'We have to be criminals to do what we do.'"

tygorius··on How to become Batman
Indeed, using only a few of those tactics...

"A retired Indian Gorkha soldier recently revisited those glory days when he thwarted 40 robbers, killing three of them and injuring eight others, with his khukuri during a train journey. He is in line to receive three gallantry awards from the Indian government." [http://www.myrepublica.com/portal/index.php?action=news_deta...]

tygorius··on What would Feynman do?
Agreed. This was a cartoonish version of Feynman I found rather pathetic. It is missing the recurring themes of learning and experimentation found in real Feynman stories. Either the old barometer story or the manhole cover story are far superior to this blog post.
tygorius··on What would Feynman do?
their primary property is light production, heat is a secondary feature

Hmm, not necessarily. Back in the days when this problem was originally offered incandescent bulbs were by far the most popular light source for facilities, and if you look at a graph[1] of such a bulb's output, you'll find the fast majority of it is below the threshold of visible light -- the real primary property of incandescent bulbs is IR (heat) production. As a physicist Feynman would be well aware of this, and hence I think he would approved of the low-tech intended solution over the suggested alternatives.

If you posit fluorescent lights, the traditional solution would still work. LED lights weren't stipulated as a special condition and even they are stated, they're not 100% efficient and hence might well work with the traditional solution.

tygorius··on Nokia’s Suicide Note
Never having seen the code, I can't say for sure that there's no Symbian OS code in the S40 series devices. I can say, however, that there's no Symbian OS access for developers in those devices. The S40 phones are semi-smart -- they allow J2ME applets to run and that's it.
tygorius··on General factor of intelligence g, a Statistical Myth
Can you start going to the gym and get stronger than your friends who don't go? No.

Presumably your circle of friends consists of people who are already physically active. Even so, I doubt your assessment concerning strength training. Looking at the people around me, I'm guessing fewer than 5% (not 80%) of them are up to 100 pushups [http://www.hundredpushups.com/]

tygorius··on Ubuntu 11.04 "Natty Narhwal" Will Not Have A Release Candidate
Interesting that, in these secular times, a stated reason for not doing a RC a week before shipping is that Easter weekend would overlap the crunch.

Not that it makes it that different from previous releases, but with the Unity UI shift and related changes it seems like there's still a lot of work to be done before release. Viz [http://www.ubuntu.com/testing/natty/alpha2] and the description of the Desktop Edition:

"Unity is now the default in the Ubuntu Desktop session.

This is partially implemented. ...."

tygorius··on 10 Reasons To Buy A Tablet (And 5 Reasons Not To)
There's a difference between significance and buzz. Netbooks were refinements of the laptop at a better price point. I don't think either category is going away anytime soon. Heck, given that even netbooks let you drive a desktop widescreen display, it's astonishing that desktop machines are still kicking around.

I'm obviously not a member of the iPad's target audience -- they can have my keyboard when they can pry my cold dead fingers from it, etc. But I appreciate the appeal of computers that can be held in one hand. Over the years I've had several mini-laptops (anyone remember the Toshiba Librettos or the Sony Picturebooks?) In most respects the netbook has hit the sweet spot for me.

tygorius··on 10 Reasons To Buy A Tablet (And 5 Reasons Not To)
Interesting that your chosen alternative was a laptop rather than a netbook. Along those lines, if you think in terms of the evolution of personal computers as desktop -> laptop -> netbook -> tablet, that last step is a puzzler.

If you take the author's 10 reasons and strip out the stuff that's a retread of previous products ("Look, it's portable! And OMG you can watch movies!") it seems to me you're left with one key point: the user interface makes it fun & easy to use. I don't think it's an accident that the only two tablet platforms that look viable so far, Apple and Android, are based on years of usability testing in the smartphone arena. Tablets may be computers inside, but in terms of product design they're consumer entertainment devices.

tygorius··on 1000+ Nokia workers have walked out in protest (in English via Google Translate)
No, stagnant would imply things were stable and they're clearly not. You can make an argument that Symbian OS was successful in the past, but the trend in the GigaOM chart you linked is pretty clear: rapid decline. In 2007, Symbian was around 2/3 of the total smartphone market, and two years later it had fallen below 50%. During the same period, RIM almost tripled its market share and the iPhone and Android numbers were showing even stronger growth.
tygorius··on The iPhone Nano Rumor Reborn: 1/3rd Smaller, Older Components, $200 No Contract
Agreed on all your points. Given that this rumor has been around since last year, I'm inclined to think of the iPhone Lite as a contingency plan and/or leverage for negotiations with AT&T and Verizon. Revealed properly, a gun doesn't have to leave its holster to be effective.
tygorius··on Great Math Books as Recommended by Our Readers
This highlights one of the weaknesses of the list -- the apparent lack of an editor. Whereas shou4577's comments explains the book's strengths and target audience, the original submission's description was so concise as to be near useless ("Coherent overview of all of pure mathematics.") This isn't intended as a slam of the original suggester, but to point out that the blog listing is only a starting point and in some regards less useful than the topic book lists some Amazon reviewers compile.
tygorius··on Why Alto? Butler Lampson's Historic 1972 Memo
I'm a huge fan of Butler Lampson, but I must confess the thing that most struck me at the beginning were the machine specs in contrast to today's machines. 48-64K of 16-bit words with a 10 MB hard drive, woohoo!

The display size and orientation is a little disconcerting, though. You mean there was a time when computer screens weren't optimized for playing widescreen movies?

tygorius··on Why I Write Books Even Though I’ve Lost Money on Every Book I’ve Written
Perhaps. Or perhaps the agent had already told him obliquely and the author didn't want to hear it.

We know from the story that the agent had previously done his job -- selling the author's books for increasing amounts of money despite declining sales. And we know from the story that after he meets with Hollis and is told the proposal reads like a crib from Wikipedia, he goes home and writes another proposal for her. And what happens? She likes the ideas but not the writing. And when the WSJ steps in, again it's for the ideas -- they want a co-author for the writing part.

Perhaps the agent should have been more direct, "Jim, the word on the street is that you're a one-hit wonder; that your ideas are great, but your writing sucks. What do you say I check around and see if I can hook you up with a co-author for the next proposal?"

Put this in HN terms, if people like your ideas but aren't willing to fund your startup, do you think it's someone else's job to find out why?

Frankly, what I found most alienating about the story was the me-me-me focus. (I mean really, going unsolicited into stores and signing books with random messages?) Too bad there was so little focus on providing value for his readers. Once I hear an author refer to a book of his as "garbage", I'm inclined to agree with him and dump him from my recommended list.

tygorius··on Why I Write Books Even Though I’ve Lost Money on Every Book I’ve Written
Yeah, it's nice, but it's also a total non sequitur. At the beginning of the piece he says his first book was a success and he wrote the follow-ups trying to recapture the good feelings -- apparently without success. Books take a lot of effort and may not make you any significant money. So I guess the real moral of his story is that -- if you're like him -- you shouldn't bother writing books if you're already in a good relationship.
tygorius··on Why I Write Books Even Though I’ve Lost Money on Every Book I’ve Written
You're assuming it's a big mystery why no one wanted his book proposal or that the agent hadn't previously covered this ground, neither of which is stated in the post. (Plus, this is an author who admits he's lied about his contract numbers in the past.) From my read the facts are damning enough:

* He'd gotten a big advance on his previous book but it didn't sell. (Money loser = big red flag #1)

* His reputation alone no longer sells a book idea (evidenced by the sudden need for him to write a proposal to sell a book.) (Warning flag.)

* His financial judgment is suspect. ("The Forever Portfolio" delivered to the publisher just as the market starts a giant slide.) (Warning flag.)

* His last book was, well... Here's a sentence from the first Amazon review: "That said, the book is horribly written -- the author has about 20 pages of interesting content interspersed with 200 pages of random digressions, about his love of computer games and the longest words in the English language." (At the very least, a warning flag.)

* His proposal read like it was cribbed from Wikipedia (Big red flag #2.)

* He's a real peach to work with, insisting he knows other people's jobs better than they do (after all, he claims he chose the $20 price point for the previous loser, and we know how he treats his agent). (Warning flag.)

Now look what happens when that book idea (not the proposal) finally sells -- the publisher insists on bringing in another, trusted writer as co-author.

Sorry, but I don't think there's a mystery here that the agent needs to solve.

tygorius··on How to Write Without Writing
Call me crazy, but I strongly suspect that the feedback system virtues that helped Stack Overflow contributors develop their writing skills will not manifest on writers.stackexchange.com.

Many writing queries fall into the taste or reference citation categories, which aren't amenable to the correctness criteria of SO. Not to mention that there are already plenty of writing resources on the Web, so I'm skeptical of the new launch being able to distinguish itself.

tygorius··on How to Write Without Writing
Blatant? Sure. But hardly out of the ordinary when it comes to blogs.

I don't think it's tasteless, but de gustibus non disputandum est, which Phillip K. Dick so eloquently translated as "Those people can have bad taste and I don't care."
