For various reasons, that that’s not quite how it works. It turns out that switching between address spaces is relatively expensive, and so to save on switching address spaces, the kernel is actually mapped into every process’s address space, and the kernel just runs in the address space of whichever process was last executing.
I thought the BigMem kernel patches a few years back put the kernel in it's own VM, with minimal copying into userspace VM space, or am i missing something?
Maybe, if this was an isolated incident with Best Buy. But a quick search on Best Buy, Geek Squad, and Ripoff will get quite a few hits. I'd love to give someone the benefit of the doubt, but this is a bit of a pattern with them.
The margins on selling electronics are painfully thin (ask CircuitCity). Creating a misleading "oh but that's not how we meant it" as they sell low value for the money services is a common thread for electronics retailers.
You want to be new, different, trademarkable in a global marketplace. I can't wait for monster cable and monster.com to start suing each other (both are very litigious about Monster).
And your namers have no creativity. So you get sucky names.
Interesting point of view. Spolsky actually seemed to like that managers didn't mix in to day to day arguments [http://www.joelonsoftware.com/articles/fog0000000072.html]
what you're advocating is more of a steve jobs approach, where someone who has a singular vision of the final product weighs in at critical times.
Jokes aside, but a few years ago I read an article about how much the 72 virgin thing is a real enticement.
Picture yourself as a young disaffected male who has well, needs. Add to the picture no money because the demographics of a youth explosion makes it hard for any individual young man to get a job. Add to the picture polygamy, which means older men who do have cash aren't limited at one wife, so they pick up a lot of women that might be available for you. Your urges don't go away.
So, someone convinces you to blame your frustrations at outsiders. And this someone offers you a way to ease your frustrations in heaven, and in some way get back at those frustrating you. Maybe not every young man believes this, but out of a large pool, a small fraction may, and that's all you need.
Before the flamewars, i don't condone violence in general, and terrorism is especially bad in particular since it by nature targets innocent people (which should be outlawed in all religions yes?). I just think the psychology is interesting.
In the early days of Linux (and still somewhat not, though less common) a common thread here on Slashdot was that Microsoft succeeded because of 'marketing'. What about dinosaurs with neckties made you want to buy Office? Or some girl projectile vomiting made you think IE was a good browser?
Microsoft succeeded by knowing that network effects are important, and making sure everyone who could possibly run their software had it, thereby locking them in for the long term. Once they had that dominance, then they could force people to do things illegally. For those that simply say 'monopoly' and do no other analysis, remember in the early days Microsoft was just one of a few companies, and only once network effects started rolling in did they achieve dominance where they could dictate.
Linux did itself no favors by screaming 'marketing' every time there was a comparison against Windows when they could have thought how to get those network effects and push out on the desktop somewhat.
"hardly ever crashes (perhaps twice in 3 months), search is *way* improved, and it finally feels like first-rate software.".
The specific releases he is mentioning are beta. Standards for 'numbers of times crashing' are different. I am guessing, but the 'first rate software' quote may also be speaking of look and feel. Thunderbird was good, but lacked polish. I have not tried any of the 3 series, but I will now that it's golden
The MacOSX EULA explicitly states that you can only use on Mac hardware. Microsoft has no such EULA. Microsoft has no PC hardware. Your comparison with Microsoft is a false argument. Microsoft probably would be in court, but that's irrelevant. They're in a different space than Apple, not only because of their hardware/software mix, but that they are a convicted monopolist, and get different scrutiny.
It's as if a company that has an integrated hardware and software combination which has rules stating that you can only install on their hardware decided to add code to explicitly disable doing things against the rules that you 'agreed' to.
EULAs suck, but they're just doing in software what the EULA is supposed to prevent you from doing anyway. Hate this? Contribute to the EFF. I'm not sure about the law and about tying (Ford can't force you to use only Ford parts and gas), maybe someone with a better understanding than me can contribute. But your argument is basically 'something Apple said I shouldn't do but was able to do before is now taken away and now I'm mad'.
The Shack will be harder to find in searches. Just like i think Electrosol moving to Finish is horrible for them. You have something that differentiates, don't give it up.
When you can come up with a single good reason why market share is NOT a significant factor, let me know.
My apologies for my lack of clarity. My frothing at the mouth must have shorted my keyboard.
Of course its a significant factor. Even more now with always connected Internet. (There was a good book on Scale Free Network theory called Networks, but with a name that generic, too hard to find in Amazon).
But over and over i've heard microsoft apologists, when presented with a virus report, state bring up marketshare, with the implied "well the only reason is the marketshare". BS. I still remember the unconnected mac and windows 3.1 days. Windows had a 90% desktop share, but about 99.999% of viruses. Windows had tens of thousands of viruses, Mac OS 6/7? About 8 I think, and rarely found in the wild. By the marketshare argument, and with no connection to the internet which would make the 90% even more beneficial (because of Scale Free Network effects), there should be a closer ratio.
Even though i agree that marketshare would casue people to write for Windows, let's have some counterarguments for that:
Hacker A decides to go after Macs because there's more fame in Mac hacking.
B goes for macs because owners tend to have more money.
Hacker C is an MS fanboi and wants to take down some black turtleneck smugness.
Hacker D realizes mac users are complacent and don't have 2 or 3 antivirus products chewing up CPU 24/7.
Is the argument "Windows has 90% of marketshare so will have more viruses" invalid? No. It has real roots. I am objecting to it being used as some blanket excuse, that Windows has a higher marketshare and we should just accept viruses as a result and not blame poor design/coding practices.
And props to your userid. I lurked too much before signing up, and i'm stuck with a 6 digit userid:(
At some point, if i want to show video on the web, i need to choose some encoding (technically, some encoding and an envelope, but we're talking about codecs here). That is the problem they're trying to solve, have web content choices be simple, a single codec for content. I can be secure that everyone can see my vid, since all browsers will have access to that codec.
It seems you're solving a different problem, whether the browser needs to code directly against the libs for a specific codec, or some generic abstraction API. That's not the issue they're trying to solve. It's a content encoding problem, not an api problem.
there was an AMAZING study (scarcasm) done this year that came to the conclusion that given a half dozen different diets, in the end WHAT you eat is completely secondary to HOW MUCH...
I also remember a study i heard about on a podcast (60 second science, pretty good) where they found that the fattening of america is pretty much due completely to Supersizing It. They calculated the calories that we eat (farm products - feed for animals and non food uses - food exported + imported foods) and the increase in said calories in the the last few years. They also calculated the extra fat we carry around, and the calories within. They worked out pretty even, in fact we're a bit less fat than that would predict - exercise has mopped up a few pounds.
So, no more shakes that count as a meal (1000+ calories), keep away from soda (as i sit here with a can on my desk).
Most of apple appears to come from Linux because of Akamai. A quick traceroute didn't show akamai for me, but that doesn't mean tht Linux is an accelerator and not the main website.
yadda yadda MS has 90% market share so that's the reason it has malware yadda yadda
I absolutely hate this argument. It assumes such a simplicity, that the only consideration that people pick for coding a virus is marketshare of the target. Of course it's one consideration, but not the only. It,. more importantly, seems to want to wash Microsoft's hands of the problem, meaning nothing will get fixed. There are a lot of things MS can do to help the situation (and in their defense they have done some) but saying "it's because they own the desktop, nothing to see here, move along" doesn't help anyone. Including you, when your net is down because some Conficker DoS.
The problem with Microsoft is just how damn easy it is to write a virus, at least in the old days. Microsoft had a system (Windows + Explorer + Outlook) which:
made the default action (doubleclick) depend on extension
made the default actions for executable to execute
made the extension hidden by default
extended this behavior from a local, somewhat safer environment (the desktop) and pushed on to email, which is totally untrusted.
This is the essence of all VB email viruses. This bad design had absolutely nothing to do with marketshare, just made the impact much more widespread.
Also, they allowed HTML email to hit activeX, which means an untrackable email can execute code just by you opening the mail. It's the Goodtimes virus, but for real.
I personally use windows, and prefer windows, and since XP came out have never had a problem with it myself. The biggest problem with computers is they're technical machines which lend themselves to needing to have technical knowledge in order to use one safely/correctly....which the majority of people do not have.
An analogy would be that "cars are complicated now, with computers and stuff, and people need to be expected to know all that tech stuff to operate safely, so we can let them explode or catch on fire if people are not paying attention 100% of the time, because it's really their fault if the car blows up when you cross the yellow line"
Again, simplicity in argument. YES stuff is complicated, but there are a lot of things you can tie down by default. MS is driven by checkbox marketing, the more features the better. This blows up when people have a financial incentive to exploit those features.
In general, i'm not trying to be a dick about this. I actually know how you feel. I'm the same way about photos. I prefer taking pics with my film SLR on Ilford BW film because it feels more like 'pictures'. But i'm not disillusioned; other than my emotional attachment, digital photography is much superior. You can like what you like, and the physicalness is what seems to attract you. But cassettes in general suck.
Cassettes are beautiful. They are durable, unlike CD/DVDs, and I have 25 year old cassettes that still work.
Maybe if you don't play them. Tapes are a contact medium, where you need to drag the substrate across the head. The iron oxide layer definitely wears off after a while. I had a few tapes where i could notice a level difference. One of my favorite tapes got eaten (a downside to tapes - any bad player could destroy your music) and i had to replace it, i noticed a huge level difference.
The pressure pad (the little metal thing that pushed the tape against the head) could break with heavy use. I had a few that did.
MP3s, CDs and DVDs can be backed up, at least in theory (bad DRM notwithstanding). Tapes could be eaten all the time, and any copy has analog generation fidelity loss.
They are hardware
Which means it can 'break'. A cassette tape is a fairly complicated mechanical thing. And it can break, sending you to the store. Think of all the moving parts on the tape: two shell parts, possible inner liner protector, two spindles, pieces to clip the tape to the spindles, the tape itself with it's relatively fragile backing and the substrate, and the leaders which can break. To play it, you need to push this fragile plastic into the player, over and around some grabby equipment.
And then there's the cover art sitting on an actual cover.
In this case, vinyl is what you want, the surface area difference is huge. The next best thing probably would be CDs, with a larger (than cassette) and non-folded surface area.
As we've seen in the credit crisis with AIG, Lehman, Bear Sterns, 'Counterparty Risk' is no longer just an abstraction. His guarantee is only as good as the capabilities of the people standing behind the guarantee. I'm not saying it's worthless, just it's not 100% either.
And the USB wall warts are insanely expensive - about $30. Granted, they don't stop you from buying it elsewhere, and they are just taking advantage of people willing to spend that on an Apple branded product, but does Steve need new turtlenecks that badly?
