My oldest son, in his first year of preschool, had a teacher who recognized that The Officially Prescribed Curriculum was not meeting his needs, and found alternative ways to engage him. Her contract was not renewed. The following year, my son’s new teacher just had him sit by himself and read books. From a “raise test scores” perspective, the second teacher was at least as good as the first. From a “look at the classroom and see what’s going on” perspective, the first teacher was head and shoulders above the second.
Good point.

John Gruber noticed this. He made the prediction that the iPad 3 would come in fall, along with the new iPods. This would allow people to buy the iPad during the holiday season without worrying a newer model coming a few months later.

Again - you don't know what his internal process was for picking these jobs. You can't mind read and impute motivations for his selections.

And no, it's not a strawman. Lack of direction, lack of ambition, lazy, unmotivated. See how they all go together?
That "technology and liberal arts" slide was used in the iPad 1 keynote last year.

I took it more as a very public declaration as to why the iPad is successful and the other tablet products haven't caught fire yet.
I wonder how they implemented pressure sensitivity in garage band drums, I can't find any mention of pressure sensors in the screen.

My guess is that they are using the gyro for this. Is it a good guess?
Basically as per my idea(what I want from such sites), the focus should be on -

1. Validating and improving the idea through feedbacks, discussions, brainstorming, etc.

2. Maintaining a wiki/document repository for idea and its execution related planning i.e. Feature List, Designs, Marketing Strategies, Technical Architecture etc.

3. Connecting various people who can execute the idea through some startup or may be an open source project - Developers, Designers, Entrepreneurs etc. This can be done through twitter like system "Follow Idea" as "Developer/Designer/etc"

4. Encourage those who implemented the idea to share it with group.

The system should improve the raw idea to an extent so that it can be practically executed by those who are interested.

Nice hardware. But only a higher resolution Retina display will get me to trade in my current iPad.
I agree, web app + sync is the big push I would need a lot of time to commit to.

And I've definitely seen catch/3banana before. I feel like they are more competitors to Evernote than to me. Simplenote's recent addition of a list feature has me more troubled, even though they don't have an android client yet.

They don't advertise the available memory of any of the iOS devices, not even to their Developers. The community finds out on their own (usually after teardowns or writing test apps).
This was a much more interesting video than I thought it would be. I'd never thought the payment models he uses in the game would have brought the revenues they have for him. $50 for a smiley face just seems ridiculous and yet people were happy to pay for it.
The difference is that these apps were downloaded thousands of times before being removed. Getting thousands of people to go to your malicious website is probably much harder.

The current iOS 4.2 does not include any standalone Dictionary apps, AFAIK. I believe "dictionary" here refers to the system’s built-in spelling autocorrect and suggestion engine, which lacks definitions.
I think when folks are saying the most exciting feature is the 'smart covers' they are using hyperbole. They haven't gotten a chance to touch and use the iPad 2 to determine speed improvements or OS improvements. If they already have an iPhone 4, they've already experienced the excited with the cameras, FaceTime, and even how thin it is.

For everyone who is comparing this against the previous iPad and not the iPhone 4, the most exciting features are probably 1) cameras 2) A5 chip or 2) HDMI out.

He was a troll back then, too. Alan Kay used to joke that arrogance in computer science is measured in nanodijkstras. EWD could back it up because he was a genius, but it didn't win him friends.

Either way, some of the aphorisms are less defensible now. 35 years later, if something so broadly useful as programming remains "one of the most difficult branches of applied mathematics", then I think we have failed our responsibility to move the science forward.
It doesn't matter how old you are-- you can be 5 years old or 48-- there is no denying that computer programming is good mental exercise, an amazing creative outlet, and (if you're any good) a skill that can make or break your career.

I'm 23 and I never got any compsci/programming training in college. I'm now working part-time and learning programming (Java, .NET, SQL, web scripting) full-time.

Why? 3 reasons.

1) I am sick and tired of not knowing how to create solutions that add real, measurable value to almost any human task imaginable. In 2 years, I'll be able to do so much more than I ever imagined in any office setting.

2) Good programmers have the job I dream of: being able to use their minds all day to create cool stuff that other people depend on. Top talent gets paid pretty well.

3) The big secret that no one tells you in college is that if you want any decent office job in which you'll be using your mind instead of bullshit "management" or "leadership" (i.e. wielding social prowess to get what you want) skills, you're going to be programming. Want to make a spreadsheet? Guess what, John Walkenbach, the maker of the Excel Bible, says that even if you're just making a basic spreadsheet, it helps to think about it as object-oriented programming. And he's right. Especially if you're a power user of Excel, Excel == Programming. Period. Same with just about any other MS Office program.

The bottom line is that if you use a computer at work, like it or not, your freaking livelihood hinges on your ability to create and manage software and/or hardware. You might as well know what the hell you're doing.
iMovie refused to run on the iPad 1 because the RAM was only 256. iMovie only ran on the iPhone 4, because it had 512 megabytes of RAM.

We can safely conclude that the iPad 2 has at least 512 megabytes of RAM, because iMovie requires that much.

I daresay RAM will be increased to 1 gigabyte (if not already) when the retina display for iPad debuts. 4x resolution requires more RAM, as I've noticed on the iPod Touch 4.
I absolutely agree. I would have upgraded to the new iPad in a heartbeat if it had a better screen resolution.
But that statement was a fair (albeit glib) criticism of the original iPod. It never really had it's breakthrough moment until the 3rd generation.

iOS doesn't allow writable pages to be executed. As I recall that was one reason why Android 2.2's V8 javascript JIT was so much faster than iOS's.

Also, use of dlopen() is not allowed. A long time ago I heard of two AR apps that used it (they dynamically linked against CoreSurface, to copy the bits from the camera preview into an opengl texture) but I haven't heard of anyone sneaking an app using dlopen() into the store in over a year.

35% thinner, 15% lighter, HDMI out, plus the improvements you mentioned... it's not revolutionary, but it's a strong second showing I think. It'd be nice if it was a lot lighter, but that's battery tech and the 10 hour choice speaking.
Yes you can. You just have to adjust your expectations.

Facebook could (and probably does) collect the data necessary to track people around the web, whether or not they click on 'like buttons'.

Whether other sites, like Google, can do this too, is immaterial. When people are logged into Facebook, an ever increasing slice of their browsing history can be logged and tied to their real identity. Almost none of the people I know who aren't hackers have any awareness of this.

Tl; dr: Somethings will probably be learned quicker if coding with a team/more experienced developers. Architecture/security/design/layout stuff that just takes years of experience to get really good at, for example. I'm learning to code also but have been learning primarily on my own. Perhaps a combination thereof would be optimal.

Thanks for this comment. I started coding about 8 months ago and am enjoying it thoroughly (I just turned 30 and have a background in business). I was actually thinking about doing the same thing this guy's done - get a developer intern position somewhere since reading this post earlier this morning. I'm sure I would learn tons that I wouldn't otherwise learn (I'm thinking specifically architectural and security type stuff, among other stuff) but am also learning tons on my own.

Just last night I was talking with a good friend that has been coding for 15 years and he suggested something kind of similar: fix the bugs and maintain some code that a more experienced developer can check - run errands so to speak. That way I'm not breaking something or pushing insecure, buggy code into production. I think a combination of the two would be optimal.
Ask HN: From a free product to a commercial product
Greetings,

Nearly one year ago I released a free .NET profiler [1]. I started coding it to solve a unique problem; a problem none of the available profilers could help me with. It was a fun experience and a much needed break from the day-to-day business of shuffling data between a UI and a db. Due to this joyous experience I created a generic profiler in my spare time and, as previously stated, released a public free version - mostly just for the fun of it.

I focused almost entirely on coding features that were interesting to do, but not all that useful in terms of profiling features or problem solving. A few months ago I started thinking how much fun it would be to get paid for doing this kind of programming and started to focus on making the profiler more useful. The ultimate goal is of course to turn it into a mISV and eventually make a living of it.

So do any of you have any experience in re-launching a free software development tool as a commercial one – or know of any tales in that category?

I am currently thinking of giving the software a new name and a new site (name and site already known and registered) and sort of start from scratch. The current versions will continue to work, but will not be updated.

Marketing seems to be the major factor of success – it is also the area where I have the least experience. Besides the ambiguous advice of creating a blog, what other marketing areas do people have good experiences with?
I have already used Google AdWords a bit and made one comment about the profiler on a MS MVP's blog – so far the profiler usage is in the very modest range [2] - probably due to the lack of marketing and lack of useful features.

I would love to hear tales of the yields of investing a significant amount of cash in the marketing effort of development tools (magazines, conference stands and similar), compared to just let it grow more organically (with a modest AdWords budget) - and of course any other advice people might have.

Thanks!

I don't understand how it validates - I'd always understood that html, head, [title] and body were required for a complete document. Certainly the draft spec at http://www.w3.org/TR/html5/semantics.html#the-html-element-0 appears to confirm this ...

Fairplay to them though, they got a semantically and structurally deficient document to validate - it's like the IE6 of webpages ;0)
The color was just an example. My actual point was that the pages had been updated before features were announced.
"this cover looks like it could solve the ergonomic problem of typing on your iPad or watching a movie/TV show while you're not sitting on a couch."

This is just another way of saying that tablets are a horrible form factor.
My guess: fingers are soft, and more pressure means a wider area of finger is in contact with screen, and that's what they're detecting.

But sensing the vibration of a more vigorous touch would be interesting, too!
A4/A5 includes RAM in the package, not flash. The flash used is in standard packaging, soldered to the motherboard.
I'd like to see a list of these 'many' different systems that have been tried.

It seems to me as though we've tried 'kings/dictators' lots of times, and we've watched communism devolve into 'kings/dictators', and we may very well be in the process of watching capitalism devolve into 'kings/dictators' as wealth and political power seem to being concentrated more and more in the hands of a small group.

I personally agree that blaming others doesn't help. Each individual makes their own decision in the end.

Except that most people are forced to go through more than a decade of training to accept employment by others and do as they are told. That puts people at a disadvantage when it comes to learning how to act independently.

The solution may be for each person to make their own choices, but it doesn't help to pretend that there are no forces working against that.
Hopefully this will put a dent in SMART's Sympodium series, which in my experience is vastly overpriced for the way it's used. Three grand will buy you a pen-screen monitor that is wired in-between the computer and projector.

Because of the cost, most places will not buy dedicated podiums: ours had to be carted around and wired into the computer setup for each professor.

An iPad is much, much more easy to deal with (everything's one unit) and there's a likelihood that the professor may have one of her own, meaning the tech doesn't need to set up what's needed.
However, is it fair to compare student pay to professional pay? On the strictly fiscal side, there is the general unemployment rate to consider as well.
I respect your opinion, but if you had read the entire story, you would have noticed lessons learned #4 & #5 at the bottom touch on those exact points: Use multiple sources, submit multiple types or genres and be sure to participate on other members' threads.

I also took the time to list the various types (ie. policital, search, acquisition, PR / branding, startup, tech / web standards, business / entrepreneur and funding related). For instance, how is the Egypt conflict considered tech/startup gossip?

As I said, I respect your opinion, and am sorry that you feel my submissions are 'kinda boring'. In response to that, I would have to respectfully disagree. That said, I am new and I'm still learning some of the ins & outs, but will certainly try to do better in the future.
Sorry, you're right. It's still discrete packages.
Nada (from what I can tell) clarifying subscriptions, especially as related to Amazon and Netflix. That disappoints me.
Add a bunch of shit that could be trivially added if you still had macros.

... only now, they're standard, first-class citizens across all code using the language.
This is an interesting idea. If one wanted to attempt a mechanism like this in iOS, what APIs would be useful? I don't know UIGestureRecognizer & friends very well at all, but it looks like it wouldn't help when needing to measure contact-area at a given contact point. Any iOS programmers here that know?
See step 16 of iFixit's iPad teardown. Looks like both ram and flash are separate assemblies. Only the iPhone has the ram integrated with the CPU package.
Good point. Somehow it didn't stick with me that it was used before. But, I think the tone is very different in this context. It's hard to pin it down, but the way he used it previously seemed less reflective and more promotional. Of course, the re-use could just be incidental, but I think its re-use may give it even more weight.
LISP's syntax is so atrocious that I never understood its popularity. LISP's possibility to introduce higher-order functions was mentioned several times in its defence, but now I come to think of it, that could be done in ALGOL60 as well. My current guess is that LISP's popularity in the USA is related to FORTRAN's shortcomings.

The memo you're quoting[1] is a lot milder about Lisp, but doesn't come across as the ramblings of a "Smug Lisp Weenie" (disclaimer: I'm currently having a lot of fun playing around with Clojure, so I might not be entirely objective).

Teachers don't see that many kids in a year. Breaking them down into a combination of a few demographics is oversimplifying things to such a degree that I really don't get how anyone can be so blase about it.

I mean, just to start with:

* Are our tests measuring the right things?
* Are we measuring the right things about the kids?
* Are we capturing all of the data for the things we do measure about the kids?

Those are huge unanswered questions to just be like "oh yeah just average the results for the income quintile, bang, done, we know who the good teachers are".

If a student's being sexually abused at home, and test scores dramatically decline year-over-year, is the teacher a worse teacher for it? Just one edge case. Throw in 4 more and you've got a significant fraction of the scores that the teacher will be evaluated on. These are students' futures and teachers' jobs we're talking about, remember.. I think general teacher resistance to having some sort of oversimplified system shoved on them from above is a feature -- that system needs to be good enough to buy them in before being implemented.
gtasks sync could cover the web side until you can build your own web app. :)
P < 0.05? That's terrible! How will the education system survive?

On the other hand, lets compare it to our current system of ignoring teacher quality. Assuming 25% of teachers are significantly above average and 25% are below (anyone have data on this?), that's a 50% error rate.

Let me just address your main statistical misconception, however: You can’t assume that after all the measurable factors in your statistical model are taken into account, the only remaining input to performance is the skill of the teacher.

This is not an assumption. The assumption is that after all the measurable factors are taken into account, the remainder are unbiased (i.e., have mean 0) or at least have bias smaller than ignoring all data.

Can you hypothesize an external factor which would, in a single measurement period (either a semester or year), significantly reduce the scores of 20-30 students of a single teacher while not affecting the scores of other demographically similar students? And do you really believe this occurs so often that it would make measurement worse than ignoring all data?

Ah yes, "intellectual understanding and rationality", the two emotions I want most connected with my next birthday.

(FWIW, I actually agree with you, and I imagine there are a lot of others. The hardest part is interacting with those who don't view rationality as an appropriate filter for a celebration, especially celebrating things like 'your not dying in the time it took for the earth to complete a full rotation of the sun', or 'a family-centric federal holiday to mark an apocryphal historical event that has developed societal importance'.)

Apple’s Scheme To Thwart The American Feds And EU With iBooks
It's simply a unit of measurement that I personally use to gauge the quality of my HN submissions and their impact on the community. Since karma incorporates both submission and comment points it made the most sense for me to use that as the main factor.

The reason I take the time to put these goals in place and track them is because I want to do better, I want to be well received, I want others to listen when I comment, and so I'm not sending things into submissions that don't belong on HN - among other things.
The rumors have always been the same as the iPhone 4 (512 MB), but Apple never releases the memory specs of their non-PC products.
It's gotta be at least 512mb like the iPhome 4.

Unfortunately, I don't think it'll have 1gb. Apple loves their margins too much, I think.
Here's my opinion, build another app, or better yet build 3 other apps and diversify your income. 1 mobile app is not enough to require full time dedication, but having 3 or 4 apps to cycle between will keep you busy and should provide good money.
Nitro is Apple's branding of SquirrelFish Extreme, which is part of WebKit.

It turns out that the highest rate of entrepreneurial activity in every year between 1996 and 2007 belongs to the age group between 55 and 64 years...Meanwhile those aged between 20 and 34, "which we usually identify with swashbuckling and risk-taking youth, has the lowest rate", wrote Dan Stangler, one of Kauffman's researchers in a report..."Perhaps most surprising," Mr Stangler added, "this disparity occurred during the 11 years surrounding the dot-com boom, when the young entrepreneurial upstart became a cultural icon."

Not so surprising once you realize there are 100 million baby boomers, many of whom would have loved to start a technology based business when they were younger...if only the PC and the internet existed.

Now that the technology has caught up, the pent-up demand can be released.

The screen is rigidly attached to the rest of the device, so yes, it should be possible to use the accelerometer (F=ma) to measure a force applied to the screen.
