I'm not sure how I feel about static typing in Java, but it does do what OP talks about, because by default you're not playing devils advocate with reflection. Static typing can guarantee the functionality of quite a lot of code

> Do experienced java programming concatenate a bunch of strings together, or is there a format method? Yeah, I've seen this a lot. IIRC, String concatenations with the + operator are compiled to use a StringBuffer for efficiency. T

This seems like an arbitrary comment. He was writing about the choices and mistakes he made. He could avoid "I" but then start blaming his problems on other people.

In reality, it probably was not open for debate. This is third grade math, remember. The student probably spent the last three problems working similar questions covering ratios/fractions. And the student probably spent at least a few weeks

Absolutely. The test was probably written by the person grading it to cover fraction/ratio problems. The question shown is a poor rewrite of something like, "If it takes 10 minutes to fill two buckets, how long does it take to fill three bu

>Should really every programmer know it? This lame comment comes up every time I see something like this posted. You're right. Knowing exact latency numbers is probably not going to change how you program, or how I program, or how most

I'm not sure I agree with your temporal notion of difficulty. One thing is not harder than another simply because the latter took less time to figure out. So what if many people have failed?* If someone with great insight like Ramanujan com

If the goal is to be happy and if some people find greater happiness doing 'work' while others find greater happiness devoting time to 'life', then surely there will be some people who will split their time accordingly. Maybe it's not techn

But I don't think the two envelope paradox has anything to do with that practical impossibility. It is about the rules of symbol manipulation and modeling. Exactly this. The two envelopes paradox is a paradox only because using a fallacio

You're right, but he's claiming this at a lower level. I imagine it's more embarrassing to have to ask, "What does this say?" than to have to ask, "How much change should I receive?"

From a linked article: According to a study by the KCC, malicious comments accounted for 13.9 percent of all messages posted on Internet threads in 2007 but decreased only 0.9 percentage points in 2008, a year after the regulation went int

From the article: i [sic] find C to be the language that every first time programmer must learn. Well, yes and no. I say no because, on Windows, C is not one of the easier languages to set up. I wouldn't recommend Visual Studio (or any ID

Isn't it? I was briefly using all of the space on my widescreen display while browsing. Certainly an improvement over vertically-scrolled websites where margins are often just blank space. It looks like you still get vertical scrolling on m

I agree with your sentiment, but it's plain ignorance to believe that those "war simulations" or any other software developed by the military is always intended to raise the kill count and not prevent casualties. To make my point, I would b

That part struck me as embellished writing (or perhaps the tour guide exaggerated that point). I hardly know a thing about the sensitivity of explosive weapons, but consider the importance the Soviets placed on secrecy. If there was such a

If there's a day chosen on which anti-SOPA sites are urged to black out (which there is), I feel like HN would be obligated to comply based on the sentiments of the community toward the bill. And so what if HNers know about SOPA? It's the a

It's only been a day or two. GoDaddy is getting free press but bad press. It's getting name recognition but not the kind it wants. This will have a dramatic effect on the image of the company, and personally I want to see how GoDaddy handle

Wallaby isn't the same thing, is it? I just looked it up (and I don't know Flash, so correct me if I'm wrong) but from Adobe's website[1], Wallaby works on FLA files and Swiffy works on SWF files, the key difference being FLA is the working

This is actually an article about x86 and ARM processors, rather than Intel against ARM. If you're talking about companies, AMD is really the one playing catch-up. But I don't see x86 going away until Windows is gone, or until Windows becom

This isn't really a new idea. Einstein had always been unsatisfied with the probabilistic aspect of quantum mechanics that became accepted by the scientific community. A very good, non-technical read on the topic that I would highly recomme

Nothing "stupid" was pointed out. It's a perfectly reasonable correction, although the original poster probably only phrased it that way since only "HNers" would see his post. And I know what you mean, but I hope you at least realize the in

"Asking students what they think they need to learn? Problem is, they don't know..." This is typical of a teacher giving his or her students too little credit. While this may be true of elementary- and perhaps middle-schoolers, I'd say most

I disagree. While Pwn2Own is not evidence of the relative security of browsers, I don't see how it can be "harmful" when it causes Google and Apple to find and ship numerous fixes for the competition. It also raises awareness to the general
