  1. Re:Not for any definition of "real time" that I kn on MSL Landing Timeline: What To Expect Tonight · · Score: 1

    Owing to the fact that we will know the lander has already reached the surface (in unknown condition) by the time we get the first signal it has entered the atmosphere, the delay cannot *POSSIBLY* be considered real time because too many events that can or will affect the system will have occurred by then.

    But since the information reaches us as quickly as reasonably possible it can still be considered real-time. (I said "reasonably possible", since there's some finite processing time that's incurred when an event is recorded, encoded for transmission to the earth, received, decoded, then broadcast to the world which means that it will take longer to receive the information at home than is physically possible if we all had telescopes that could resolve the landing in "real time").

    Otherwise, where would you draw the line?

    Does a solar satellite give us "real time" information about the sun even though any data it receives is already 8 minutes old? Do we have "real time" communications with a lunar lander, even though everything it sends has a 1.28 second radio delay? Can we watch events at the London Olympics in "real time" even if codec and satellite delays delay the signal by a second or two? If you watch a sporting event live, are you really seeing it in "real time" since you're not seeing the action 100m away for 833ns.

    I find my ability to retain information increases greatly if I pay attention. If I'm writing, I'm not paying attention, I'm just a passive conduit for words going in my ears and out my fingers. If I do take notes, I generally find myself wondering what the hell I meant. Better to just pay attention in class and read the text. Notes are worthless.

    For me it's the opposite - when I'm in a meeting, I write down anything that I feel is important and I find that I retain it better after the meeting. I almost never refer to my meeting notes after a meeting (and I have no real organization system that would let me easily find the notes a few weeks after the meeting aside from flipping through my notepad), but I tend to retain information much more after I write it down.

    Or maybe I've trained myself to work that way so it's just the fact that I'm writing it down that makes my mind see it as "important", and has nothing to do with the actual act of writing it down.

    I've tried taking notes by laptop, but I find that I quickly forget anything that I've typed in (with the plus side being that I can search for and find typed meeting notes later on if I need to)

  6. Re:The price the phone to the users on RIM CEO Says Company 'Seriously' Considered Switch To Android · · Score: 1

    If you're building a phone for executives ONLY, then make it a $1000 phone. These are people who drive 911's, M5's, Ferrari, or some other similarly high-end car. If these are the people willing to spend $300,000 for a top-of-the-line supercar, then they certainly should be willing to shell out $1 to 2 thousand for a phone. But it better be the best damn phone there is.

    I mean, if you're paying 2k for a phone, not only should it make the iPhone look like a cheap toy, it should make almost all high-tech items look like cheap toys.

    But the problem is that Apple, Samsung and HTC are all making really, really good hardware, and selling it for $200 -- a tenth of the cost. And for all of RIM's wizardry, they aren't going to beat Apple.

    So, the executive who is paying enormous sums of money for a car is going to look at the Blackberry, then look at the iPhone, and still decide that the iPhone is the better product, even though it's cheaper.

    RIM needs to get their act together and make some really smart decisions. Unfortunately, they are not.

    A $1000 (or worse $2000) phone will be less capable than any iPhone or $500 Android since your sales will be in the hundreds of thousands, maybe low millions if you're lucky, versus the many millions of Android and iPhones sold.

    The raw materials build a phone are a small part of the total costs -- estimates place the iPhone at around $200 for parts alone (of course, they can keep costs down by buying entire factory production runs). The biggest expense is the billions of dollars of R&D that goes into making a modern smartphone. If you spread it across many millions of phones it makes the R&D cost per device much lower than if you can only spread it across a hundred thousand devices.

    And even if you have $1000 to spend on parts for your high end phone, you still have the exact same power, weight and size constraints that the guys building the more popular phones have. And 6 months after you release your phone, the other guys will have already leapfrogged you with a faster more capable device using faster, cheaper, smaller hardware.

    Exactly. Absence of a confirmation is not confirmation that there is no order.

    In that case, the transactionally correct action would be to cancel the original order,
    and receive confirmation of the cancel, before attempting to place another order.

    That depends on what the protocol spec says. If NASDAQ acknowledged receiving the order but didn't confirm that the order was placed, it's entirely possible that the right thing to do was send the order again under the assumption that it didn't get filled.

    Of course any system that doesn't use unique transaction ID's to prevent dupes is braindead, but I've been appalled at some of the brain dead protocols I've seen that are used to transfer large volumes of transactions amongst businesses (sometimes involving someone manually keying them in on both ends with no check digits or other verification.)

    Of course... if Facebook stock had gone up instead, then they would complain that more orders were cancelled and not resubmitted than they intended.

When I was looking for an apartment, out of 12 ads I replied to, 8 were scammers of the form "I'm an out of town landlord, I can't release the address to you until you submit an application at this website" (where the website asks for everything a credit app would ask for like social security number, current and previous addresses, etc). All 8 were worded almost identically with minor changes here and there, so I suspect it's a group of scammers using the same scheme. 2 of the responses were of the type "Thank you for responding, you are the first to respond so you can have the apartment, just western union a nominal $200 security deposit to me and I'll meet you at the apartment with the keys". The other 2 didn't answer at all.

    Finally I ended up renting from a big apartment complex since I got tired of wading through the obvious CL scams and spams (like Luxury 3 bedroom apartment with large fenced yard for $1450/month (in downtown San Francisco)) only to have to wade through even more scammers that managed to put up a legitimate looking ad (which I found that they sometimes do by reposting a legitimate ad that expired from the site)

    Most of the scammers get flagged down after a day or two, but by then it's too late.

    If CL isn't going to do a better job of screening their ads (like maybe charging a fee to landlords), I wish they'd go away since "free" craigslist makes it harder for new and better services to start up - Landlords turn to CL first because it's free.

    Censorship: the institution, system, or practice of censoring

    Censor: to examine in order to suppress or delete anything considered objectionable ; also : to suppress or delete as objectionable

    From Wikipedia:

    Censorship is the suppression of speech or other public communication which may be considered objectionable, harmful, sensitive, or inconvenient as determined by a government, media outlet, or other controlling body. It can be done by governments and private organizations or by individuals who engage in self-censorship. It occurs in a variety of different contexts including speech, books, music, films and other arts, the press, radio, television, and the Internet for a variety of reasons including national security, to control obscenity, child pornography, and hate speech, to protect children, to promote or restrict political or religious views, to prevent slander and libel, and to protect intellectual property. It may or may not be legal. Many countries provide strong protections against censorship by law, but none of these protections are absolute and it is frequently necessary to balance conflicting rights in order to determine what can and cannot be censored.
