+ - Money and wealth: clearing up some serious misconceptions-> 2

Submitted by KDan
KDan (90353) writes "I am not an economist. However, most people misunderstand money and its purposes and uses so badly that I feel compelled to write out my understanding of it. Perhaps because I am not an economist, this might help some. The first and perhaps most important mistake people make is to confuse money for wealth. The more I earn, the more I realise that wealth is not money, but the ability to generate money (and other things of value). This is akin to the difference between saying "I am a dancer" (i.e. I have the ability to dance) and "I was a dancer" (i.e. I once had it but I no longer have it). Being wealthy is equivalent to the first statement, while having money is equivalent to the second."

This is a false dichotomy. Most software that uses less RAM is actually also faster.

Nowadays, it's usually faster to recompute than read it all back from RAM, and if an interactive program uses a lot of RAM, then it's likely keeping a lot of junk in memory that it doesn't need.

Wow, this is a perfect example of completely misunderstanding memory-CPU tradeoffs. No. For a non-trivial amount of data, it is never cheaper to recompute the data, at access-time. It may be faster overall, as you might be able to use the freed RAM in a better way elsewhere, but it will never speed the accessing task up.

If you recompute the data constantly, it has to hit RAM and then read it back, unless you're dealing with a dataset small enough to be stored completely in cache, in which case this is a nonissue anyway. More caching is never a bad thing, so long as you set smart defaults for how the caching is done, and you allow the users to configure it. More RAM, in the hands of a smart developer, is a Good Thing (TM).

You don't even need to go the FPGA route. The baseband firmware on the iPhone has been patched for an unlocking, there's nothing stopping someone from patching it to change the IMEI built into the phone or the IMSI it "reads" from the SIM. Change these and the phone can become any other.

What Do You Call People Who "Do HTML"? 586

gilgongo writes "It's more than 10 years since people started making a living writing web page markup, yet the job title (and role) has yet to settle down. Not only that, but there are different types of people who write markup: those that approach the craft as essentially an integration task, and those that see it as part of UI design overall. The situation is further complicated by the existence of other roles in the workplace such as graphic designer and information architect. This is making recruitment for this role a real headache. So, how do you describe people who 'do HTML' (and CSS and maybe a bit of JavaScript and graphics manipulation)? Some job titles I've seen include: Design Technologist, Web Developer, Front-end Developer, HTML/CSS Developer, Client-side Developer and UI Engineer. Do you have any favourite job titles for this role?"

North Korea Missile Launch Fails 609

An anonymous reader writes "Remember the Intercontinental Ballistic Missile launch by the North Koreans last night? You know, the one that went over Japan and supposedly put a 'communications satellite' into orbit. Well, according to the US Northern Command and NORAD it has been a complete and utter failure, with the second stage and payload 'falling in the Pacific.'"
