No offense, but that's what's known as a "sucker price". Vegas hotels do the same thing. The only reason they charge that much is to try and price discriminate against people who don't have a choice or don't know how to get a better deal. I guarantee you that the amount AT+T is actually subsidizing is not that high (granted, volume plays a factor). For a fairer picture, try looking at European markets where the phone has to be sold non-discriminantly in the absence of a plan.
RS232 is the dead simplest way to talk to electrical devices, it'll live on for people working on prototype and specialized hardware, where it doesn't make sense to waste time on the USB logic/hw.
That said, it's a small niche, and I'm perfectly happy with the many USB to RS232 dongles out there.
The problem lies wherein you want an API to do something, and it doesn't.
FTFY. This isn't in any way a new problem. Witness Hildon/Maemo, and Android. They all have approaches for handling multiple user-interfacing applications and how they interact with power management. Apple has chosen an approach, and it looks good enough for 99% of use cases. Everyone who is still complaining at this point will continue to do so until they get real preemptive multithreading, which is not necessarily wise to allow for arbitrary apps on a mobile platform.
Even more generally than all that: An API does something, but you want it to do something else? Name me an API that *doesn't* have that problem. Combating feature creep and having a consistent and sensible development paradigm is really *hard*, and it looks like Apple is serious about it.
More specifically, you see at-replies for people you're also subscribed to. There are corner cases that bug me, where A at-replies to B about something B at-replied to C, when I only follow A and B. But you can't really do anything about that, and most of the time I can derive most of the context anyway.
I don't agree that that's a good thing in any way whatsoever, because sooner later this stuff does affect everyone negatively, and then it's too late.
No, that's selection bias. *Occasionally* this stuff does affect everyone negatively, and it's tougher to get rid of. But for every case of Microsoft Office file formats, there's a thousand cases where Slashdotters cry fowl for something that really doesn't matter (Google collecting data from Chrome).
I will happily grant that in the cases that matter, it's easier to address issues before they become issues, but the way the tech community crows, it entirely dilutes our credibility and makes us seem like the elitist smug characature that comic paints.
If ever there were a case for +6 scores, your comment would be a candidate. The sentiment you so incisively and concisely express applies to other things covered on Slashdot, too, including ISP/Cable markets, cell carrier markets, end-user software, SaaS/the-cloud, Microsoft Windows, and Google Chrome.
People don't care about theoretical problems, they occasionally-but-rarely care about actual problems that don't affect them. They don't care about features they won't use. They DO care about things that make their lives more interesting, fun, or easy.
Slashdotters complain that's being short-term sheeple. I say it prevents oversensitivity to things that turn out to be non-issues in practice (at the cost of being unprepared for maybe 1 in a 1000 edge cases).
One of the things that I find really unjust about our system, taken as a whole (which is dangerous in a federal system, I know, but bear with me) is that when a normal person is robbed, the state gets to fine the robber and keep the money. The victim of the theft is left with some abstract "justice" in the form of an imprisoned thief and the state pockets the fine instead of transferring it, tax free, to the victim of the theft.
You're confusing criminal and civil law. Restitution need not be a goal of criminal trials (although it's often added to sentences anyway). But the victim is free to pursue a judgment in a civil trial if he thinks he's been wronged, regardless of the criminal outcome. That's what civil courts are there for.
In that sense, it's like a battle to control people's expectations.
Very well said, it seems like that's exactly what it is.
In that case, if mobile phone users become "used to" paying for ringtone versions of songs they already have, or getting charged disproportionately large amounts of money for simple features like text messaging, or arbitrary restrictions on how they can use "unlimited" data plans, or (as in the case of Apple) losing the right to install software that's not been authorized by Apple - then will these policies then be OK?
Pretty much. I know a lot of times on Slashdot people have a hard time accepting that markets in different part of the world behave differently, even on the demand side. What people have gotten used to accepting in one part of the world isn't the same as another, which is why Japan has a market that (at least until recently) has been ok with the Sony corporate-controlled-standards, more-features-is-better, mindset. And Europe has great cheap 3g cell phones and service. And the US has cheap video games and DVDs.
They're all features of a market that has gotten to where it is for whatever historical, social, or otherwise reasons. Apple, in this situation, has done an amazing job of CREATING* a mobile app store market out of the pre-existing cell market, and I give them kudos for that. I disagree with the way they do business, and it's not for *me*, but I don't begrudge them the right to look for people who are happy doing business that way.
*Okay, they weren't the first, but the first at anywhere near this scale of popularity and profitability.
Rivalrous is commonly used to mean something akin to "scarce". As in, like physical goods that can be lent, resold, or even stolen, unlike normal bits which can be copied infinitely.
Really, what is there to do on a cracked PS3 that can't be done on a 360 or Wii aside from things that use the Cell Processor which only really does obscure mathematical calculations very well.
Play copied PS3 games. I think from Sony's point of view they have more than made back their investment on DRM for the PS3.
It's an interesting technical proposal that might makes sense some day when we have infrastructure there... but putting infrastructure there solely for that purpose doesn't seem like something that would be financially meritous.
Either way my point was that the absence of such a thing is not something that's holding back present Mars missions.
2) Escape velocity doesn't give one a good idea of how hard it is to actually escape. The more mass you are carrying the more energy you need. Giving acceleration is far more descriptive.
3) Measuring gravitation with escape velocity instead of acceleration, and not making explicit note of it, makes you look like a dumbass.
Actually both tell only part of the story. Acceleration due to gravity tells you the minimum amount of impulse a rocket needs to deliver to temporarily escape a surface. But orbital velocity tells you the amount of integrated impulse needed to STAY above a surface. If you just went straight up above the earth to the elevation of the ISS and turned off your engines you would promptly fall back to the ground (g at the altitude of the ISS is a little under 9 m/s^2).
Delta-v (of which escape velocity is one example) turns out to be a very convenient measure of energy needed to attain (or brake from) an orbit for two reasons: in the absence of non-conservative forces (i.e. drag from Earth's atmosphere) it's a state function of the orbit (or surface), meaning calculations are simple addition and subtraction, rather than integration. Second, rockets deliver power in units of "impulse" which is the amount of momentum imparted per unit time, so energy costs are a matter of dividing (delta-v*mass) by impulse. In consideration of those facts, your third assertion makes you sound very ignorant of the way people who do orbital mechanics actually work.
GP's usage of the escape velocity of the moon is not unreasonable in its context.
You're adding technical complexity that's not needed for something like a Mars trip. We can boost people to sufficient delta-v for Mars transit, that's not (comparitively) difficult. Even if it were difficult to do in one go, we have the technology for orbital rendevous to make that work (given all our ISS experience). The energy costs are "just" a matter of throwing enough money at it (and it's not a prohibitive amount). Putting people in a confined space for a year for the Hohmann transfer to Mars orbit and having them come out the other side not suicidal is IMO the more challenging aspect.
That's a heck of a generalization without support. Do you have evidence to support that domestic newspapers *aren't* reporting accurately on this topic? Otherwise, why should I be offended that other countries in addition to our own produce quality journalism? I'll gladly listen-to/read British reporting alongside NYT and other sources.
Centrifugal force is the apparent outward force that results from constant acceleration tangent to the circumference of a circle (constant angular acceleration).
Centripetal force is the real force that counters the apparent centrifugal force, by a tether or a platform.

Actually that's one of my largest pet peeves about Chrome on Linux: Opened files get saved in ~/Downloads, even when I don't want to save the file, which clogs up the directory with tons of files I don't care about and takes up disk space. Firefox puts those files in/tmp, which I consider the right approach.
Whilst initially targeted at high-end servers, Intel's long-term goal was to make Itanium the de facto standard 64-bit replacement for the aging x86 architecture in other markets. During the 2000s, however, AMD developed a 32-bit compatible 64-bit extension to x86 known as x86-64, later also adopted by Intel itself, which largely replaced 32-bit chips in most desktop and portable applications. Since high-end Itanium server implementations predominantly ran HP-UX as their operating system, this led to Microsoft announcing in April 2010 that it would not release any new versions of Windows on Itanium.[5] Chips based on x86-64 were also scaled up to powerful multi-core 8 to 12 core processors, allowing them to be used in high-end server applications, casting some doubt even on Itanium's future in this area

The Descent 3 port was great! I still have that disk lying around, and it gets a play every now and then.
Can you elaborate on that? I have them in my RSS feed-reader because they're pretty much the only people who cover X and Mesa development.
For whatever my experience is worth, I bought both Oddworld games from GOG and they worked great in Wine. Then I bought Fallout and it was unplayable.
It depends on how well the original game is supported in Wine, I guess.
For that matter, how do we know which laws to follow when the courts keep changing the rules on us?
