I used to wonder about these until I got to spend some time (actually with Informix and IBM HW) working on some real DB performance testing on one of our products at an IBM capacity center. The reason for this limitation is simply so that people don't publish "official Oracle benchmarks from the official Oracle benchmark tool" when they had an incorrectly tuned DB. That's all. Like many things, its a lot less significant than it appears when you see it. Its not as if they restrict access to it for your own use.
I'd guess I'm in the other camp too. Mainly because if you're using enough resources on a dedicated machine to need to move into swap then you either have a memory leak (let's assume not, because that's a whole different problem) or you're being hammered. When your machine starts swapping while being hammered, not only does your webserver generally become completely unresponsive (swap cycles taking too long to respond properly to requests, which then get cancelled and swapped out, which then...), but now your may not even be able to SSH in without waiting several seconds (or minutes) between commands.
More often a better approach is to run several smaller memory-bound instances with something like haproxy swapping between them (and your HW LBs swapping between boxen, of course). That way if there's an actual defect, one instance goes down cleanly (and can be restarted cleanly) and the box continues to operate as expected. Between them your appserver instances can allocate all available RAM, and you only have to release it 1/n portion at a time, keeping capacity mostly up to spec.
Hmm. Other than the fact that the iPhone antenna "problem" wasn't one in the real world (as shown by the literally millions of phones sold with the problem that... worked fine), and that the 4G iPad supports native 4G connections in most (but admittedly not all) countries that offer them, let's look at the "white iphone4". Which (gasp) had a tendency to discolor. But your a fanboy if you don't stack that up against a product being reviewed that doesn't actually exist in any meaningful way.
And for systems developed with only one access application to the DB (actually fairly common these days), the sacrifice of having to keep referential integrity rules in the application layer may be outweighed by the appeal of not having to put all sorts of sharding rules into the application layer because the core DB just got faster. There are always trade-offs when you start getting close to performance boundaries of an existing solution. And if you're not - then why change?
Starting in Windows Vista and higher what you do is hit the Windows Key and just type whatever you want and it will pop up. I can't stand XP due to the lack of this as I am used to it. - Eg. Windows Key CM...(cmd.exe shows).. and I hit enter. 1.5 seconds later I have a command prompt open.
That's your reason? Feel free to not buy a mac, but Apple-Space really isn't that far away from hitting the Windows key, except that it doesn't turn a single key into both a modifier and an action.
Regardless of 'lifestyle choice', not everyone has access to quality food or the opportunity to get the execise they need in the week (lord knows I don't!).
Better yet, just use the original - vastly harder to crack, since "Mom's 9 indigo corsets inspire bitter thoughts yet purple pleases" also reduces to your abbreviation, yet would hash quite differently itself.
At least in the XP days, I've run "password retrieval" programs that were scarily fast and good at reversing the hashed passwords - even long, complex ones. Apparently there was a known weakness in the way that they were stored.
And how do you log into your bank's website from - say - your mobile phone? Or while on holiday? Do you securely tunnel into your computer to retrieve it, then dump it into the clipboard and paste it into the app? Assuming that pasting works, which it may well not for a password field. That's not exactly a sustainable approach for the masses.
Far easier to allow the long passphrase in the first place.
So what? The question is not whether or not it takes a certain amount of time to brute-force 44 bits of entropy. The question is whether those 44 bits of entropy are more or less (hint: more) than the entropy of most "secure looking" passwords.
The characters are "words in a dictionary" not "glyphs on a keyboard".
But when cracking a password, you look at "words morons on the internet use a lot" and there are probably closer to 5000 of those (compared to 50000 regular words). Combine with noun / verb / article classes and weight words with frequency and you can narrow that down to a LOT less in practice.
Pass phrases are dumb.
Of course, even if you got down from 5000 to just 500 (unlikely), that's still vastly more than the number of letters commonly used... you're looking at 500^5 instead of 26^5. Then add in apostrophes, Capitals, abbr.s, and so on...
You realize that that list includes contributions by Microsoft employees (really, by anyone who writes "Microsoft" onto their donation form as employer). It works out to about $30 per US employee...
I'm not sure it's fair to say that trucks are undertaxed. Commercial trucks make up 12.5 percent of all registered vehicles, but paid 36.5 percent of total highway-user taxes in 2006. [truckinfo.net]
Ah, statistics. Commercial trucks see far more highway miles than the average registered vehicle. And since road damage occurs based on the square of the mass of the vehicle divided by the size of the contact page, commercial trucks also disproprtionately create wear and tear on the roads.
Don't forget that, if your house is powered by coal (as many in the US are), you're still better off with CFLs for mercury reasons. Figure.2mg of mercury from each lightbulb if you just break it (and don't do that, mmmkay). Coal power releases.022mg per kwh (0.012 mg per kwh is the US-wide average). Getting cheat math from http://www.ecmag.com/?articleID=10261&fa=article (easier than going to the EPA sources, but feel free, they're listed):
A 75W incandescent operating over a period of 10,000 hours—the rated life of a competitive 18W CFL—will, therefore, generate an average 9.2 mg of atmospheric mercury emissions nationally, while the 18W CFL will generate 2.2 mg (plus possibly up to another 0.27 mg if the lamp is broken).
We have relatively cheap IKEA CFLs in all of our bathrooms, mainly because our house has decorative fixtures with 6 bulbs in them, and even smaller incandescents add annoying warmth in a climate like Texas'. We put them in 5 or 6 years ago, no problems yet with any of them. I know that the plural of anecdote isn't data, but in many cases they're just not that bad (and very reasonably priced).
And its struggling with the fact that there are too many people there for the power it has to deliver. This is one way to mitigate that, at least a little bit. Its called compromise, and while unpleasant it usually beats the alternatives.
It only makes sense that people using your software across devices will at least want a consistent UI, and it should be accessible no matter what type of device you are using.
And it was realizing that this was incorrect that caused (among other things) Apple do develop the iPhone as its own thing rather than the previous Windows phones/tablets that all failed miserably. People use different types of devices to do different things at different times. If I want to read a website I want to do it in a way that feels natural for me at the time. If I even have to think about which browser I'm using (really, even which appliction I'm using) to do so, its already all screwed up.
Let me guess - Carrier Command? One of my favorite games, even though it felt that the AI's carrier could travel at Mach 3 (or something) making it damn near impossible to target.
Mutually Beneficial Trades makes more effective, profitable and longterm alliances than indiscriminant handouts ever will. France and Germany defended Iraq up to the US invasion, trying to stop it, because of the trade they did with Saddam.
Well, and the fact that the justifications used for the invasion (WMD, 9/11) had no basis in fact. But yeah, it was all because of trade.
You may not realize it, but that site (and indeed most government reporting) combines payments from corporations with payments from individuals employed at those corporations. This is generally good, otherwise owners could just bonus themselves and then fund "anonymously" rather than have their companies make donations, but bad in that it blurs that line. Arguably, however, there is no valid way to un-blur it. Its the same data that's used by people who don't do any digging to complain about companies making donations to both candidates in a race.
Bottom line: unless all of your donors are unemployed, you'll show up on that list with corporate references.

Right...

That is why I didn't buy a mac.

It is no longer an option on the Texas drivers license.
Weird... it was just a few months ago when I renewed mine.
Regardless of 'lifestyle choice', not everyone has access to quality food or the opportunity to get the execise they need in the week (lord knows I don't!).
Highly recommended: http://www.youtube.com/watch?v=aUaInS6HIGo - bottom line, you probably do have that opportunity, and a little movement goes a very (very) long way.
You really don't want a little-used niche product in the tech world, or you'll be left out on future developments.
So... that'd mean Windows on the desktop, amirite?

This sounds like brain-dead retarded management policy. Stepping over a dollar to save a dime.
They didn't deserve you.
Except that in this case it was stepping over a dime to save a dollar. The truly vast majority of barcode scans are correct.

Of course, it could also inspire companies to make more efficient standard socket incandescents too - http://www.reuters.com/article/2011/04/29/idUS273367407320110429 is but one example of many.
