You're not a real coder unless you write your own OS, processor microcode, support libraries, network architecture and programming language before you make your application. Otherwise, you're just letting other people do the hard work for you!

Do see what a bad place this line of thinking takes you? If you want to get anything done, you have to reinvent the world. Imagine if everybody did that... how slow development would be and how slightly incompatible everything would be.

Go ahead and proceed with your elitist worldview. If you need me, I'll be over here, being productive and shipping actual products.


Laser Headlights Promise More Intense, Controllable Beams 376

cartechboy writes "Soon, your new car's headlights will be powered by lasers. The 2015 BMW i8 is entering production, and it's the first vehicle to offer laser headlights. These new beams offer a handful of advantages over LED lighting, including greater lighting intensity and extending the beams' reach as far as 600 meters down the road (nearly double the range of LEDs). The beam pattern also can be controlled very precisely. Plus, laser lights consumer about 30 percent less energy than the already-efficient LED lights. Audi is among the short list of other auto manufacturers to promise laser lights in the near future. But the coolest part of all this? When you turn on a set of these new headlights, you'll be able to scream, 'fire the lasers!'"

doing things that break browsers that are somewhat out of the mainstream (while avoiding more portable solutions), it's not even a good, well-thought-out solution. If my browser doesn't work right on a given website, it's almost a certainty that the site uses JQuery.

So JQuery doesn't support your esoteric, out of mainstream, unnamed browser, but it works just fine for 99% of the world who do use mainstream browsers. Therefore JQuery is a bad solution? JQuery only has the developer mind\time resources to support only so much stuff. They just can't support everything, as that draws time\attention away from making the mainstream use cases work (read: use cases that are important to everyone else).

Faulting JQuery for not supporting your oddball browser is like faulting Adobe for not bringing Photoshop to FreeBSD; there are precisely 6 people who would use Photoshop on FreeBSD, so they choose to spend their time on other things.

Do you really want to sap the performance of your script by following the JQuery ethos of using expensive DOM-query navigators for every operation instead of simply gathering up an array of element references only once and then using that repeatedly?

Who says you have to query inefficeintly? Just query once and save the result somewhere. Just because it's possible to do something the wrong way doesn't mean JQuery is bad. There are ways to shoot yourself in the foot on every platform ever made.

The problem you're having is that users don't know what they need, they just know they have problems and they are suggesting solutions for you to implement they think will solve them. The problem with that is they don't know what computers are good at so they make suggestions that sound good but are not likely to work well in practice. You need to take their requests and see what the real problem they are trying to solve is. Then point out the problems in their solution and suggest features that can solve the real problem for them. Just remember to be nice about it so they will learn to trust your judgement. Nobody wants to give in to the guy who loves to yell "I told you so"

The lightning connector is nice, but it's limited to only Apple products, thus its usefulness as a technology is limited. To reduce waste and for convenient charging, I wish everyone would agree on a nice reversible connector that is an industry standard, charges quickly regardless of manufacturer, and "just works". I somehow doubt Apple would go for that.

Micro USB is fine except the cables are always upside down (as they seem to exist in 4 spacial dimensions) and the cables break easily if you charge the phone while they're in your pocket, such as when using a portable battery.

Java and Scala can both be run in the console but, as the video shows, Scala can be run AS a console. Scala code can be run one line at a time in a Scala console or compiled. Java code can only be compiled. By the above given definition, this makes Scala a scripting language.

Scala does have similar support to eval with the ScalaInterpreter class.

The wiki def for a Scripting language is "A scripting language or script language is a programming language that supports the writing of scripts, programs written for a special run-time environment that can interpret and automate the execution of tasks which could alternatively be executed one-by-one by a human operator." Check out this video and you'll see that Scala can do this. Scala is a weird hybrid. It's a full powered language build on top of the JVM that can run as a script or be compiled directly in to Java bytecode.

digital signal all the way to the monitor means better audio quality (speakers are in monitor).

Seriously bro? Any miniature benefit that digital audio signals would have given you is completely blown away by using speakers that are integrated into your monitor. Integrated speakers are just universally bad, full stop. I'm not talking about an audiophile's definition of bad, either; I bet my grandma could hear the difference.

I'd wager that given the same sound source, a stereo analog signal going into standard desktop computer speakers will sound better than your pure digital setup through your computer monitor.

If this was a troll, well, you deserve a beer, cause you got me.

It isn't just slashdot either. Extraordinary claims + no extraordinary evidence = BAM front page of major news site + accepted as fact by 1/3 of our facebook friends.

This story is far fetched and is definately not the simplest possible explanation. I call bullshit. Slashdot should know better.

A lower sugar spike helps but in the end that sugar is still there. The so called healthy "slow release" carbs still release in the end. If the body has too much sugar available it doesn't get round to burning fat. I mean that's the argument, but you'd have to read up to see if it makes sense.

The slow release makes all the difference. The huge insulin spike that triggers the storage of ALL fat only happens when the glucose hits all at once. Slow release insulin means that both glucose and fat can be burned simultaneously as your body continues to digest the food and introduce more glucose in to your bloodstream.

So either something radically changed in our bodies in the last 12000 years, or we are eating an unnatural amount of grains.

Or the grains changed recently. White rice and white flower are much, much more recent inventions. Add to that things like the sugar water (soda, juice, and even beer) that we drink at nearly every meal and you can see how much our much our diets have changed in just the past 100 years.

It sounds like your hinting at the Paleo diet with all this. That diet does work but that's because it's a much more strict version of a low GI diet. I'm not going to argue that low GI is just as good as Paleo but it's certainly much simpler to implement and has most of the same benefits.

For anyone who is interested in the details of why low GI diets work and how we are where we are today I recommend the book Good Calories, Bad Calories

Hacking's just another word for nothing left to kludge.
