It is possible to reread some data from a zeroed (or oned (sp?)) disk. Pretty obscure, but I think it is to do with the threshold values of zero and one. For example, writing a location in sequence with 1,1,0 will result in a measurable [ though below threshold ] difference than if it had been 1,0,0. Seagate and the like do their best to squeeze this to the absolute minimum, thus maximizing utilization of the magnetic disc. I suspect it is much harder to recover anything meaningful from a 1TB platter than from a 5MB platter.
The other leak is with remapped sectors. Remapped sectors may contain live data, but have been switched out of use because they were unreliable. Flash has the same problem.
dd if=/dev/random of=/dev/sda takes care of the first problem - if you more paranoid than that, you should probably stop whatever it is you are doing.
You need a custom tool to access the remapped sectors.
The Long tail is snake oil; wishful thinking encapsulated in a sound bite. Mr Anderson has certainly demonstrated how to profit from the "Long Tail", however the business model is really restricted to just himself.
According to the great wiki god, ic engines average 18-20% efficiency, and peak at 37%; so a tank is between 100..210 kWh usable. Presuming the 18% is around city, and the more direct applicability of regenerative braking, the difference shrinks considerably.
It probably makes a pretty nice work environment. It is a reliable base, with an easy to use interface, glazed with enough apps to do what most people want to do. Sounds a bit like a macbook.
The problem with unions is they lead to abuse. Sure, they offer some efficiency, particularly over large structures, but the more modern methods deal with that quite nicely. Unions always seem to increase the verbage as well, anonymous unions and members never having been as well adopted as they should have been. They are really useful for avoiding casts; particularly when dealing with an anonymous pointer that may be one of some small set of types, you can construct a union of those pointers, then use the appropriate member when the desired type is realized. Keeps the code clean and easy to read.
yes, and a little honesty helps. Best mgr I ever worked for gave me a lecture about not taking a course. It went something like "You get evaluated in providing solutions; I get evaluated on managing you. Your checkboxes include putbacks and designs; mine include the number of courses you take." So I took a course. I thought I was doing everyone a favour by not taking them. He obviously couldn't last, I think he embarrassed too many of his peers.
You seldom know the true reasons people don't take jobs. I am offended at being lowballed, but think it is a good indication you don't want to work there anyways. Smile, nod, and politely turn them down when they make a formal offer. It may be a Canadian thing....
In case you haven't been reading the news, free market economics was just given a shit-kicking by its cheerleaders. I'm curious what will be nationalized next....
It's not just hype; Church's hypothesis asserts that lamda calculus and turing machines are equivalent. I have a slightly different problem with 'fp is the answer' in that fp implementations that do not support lazy evaluation are so slow in practice to be useless. Lazy evaluation, which is approximately caching, monitors the dependencies between entities, thus limits re-evaluation to just what might have changed. I don't really see how this relationship management can be implemented effectively without 'mutable storage', which resurrects all the problems with more conventional programming models.
An old joke goes something like this: A customer goes to radio shack to get his printer repaired. The repair guy says it will be $300, and be done in two days. Customer balks, repair guy explains the problem, and points out that the parts needed can be bought in the store for $5. Customer is thankful, but is concerned repair guy will get in trouble for turning away business. Repair guy says.... we find we make more money if you try to fix it yourself.
Other than its use as bait, FOSS enables a cottage industry for customization or repair which gives the customer choices like they have for repairing (most) cars, appliances, pets, etc...
The service industry is good work, but there is little opportunity to launch a retire-on-it type of project.

Nicaragua? Iraq?
Dates, despite the enormous historical knowledge of how to treat them, remain a mystery to most computer people.

Its Woz I tell you! He has gone mad!
Wouldn't solaris fulfill that part? Its not like esx doesn't contain an OS, it just doesn't export its interface(s).

I think the parent was employing a pun on the word charge. Like a frog, a joke cannot survive dissection.
did this 'girlfriend' keep nagging you to get a job and move out of her basement?

None of John,Paul,George,Ringo were the best either. You can insert whatever group, and it maintains.
There is a world of difference between a Product and a bucket of "best bits", and promotion is only part of it.

can we expect an onslaught of viruses? It is much easier to attack a single platform, if I understand the virus marketing info properly.

Shouldn't that be modded funny?

The long, expensive tail ? I think they should open source the iPhone, then people wouldn't have to worry about making money writing apps for it.

Good morning students, today we will learn how to mix hash and turkish tobacco so nobody will know how fried you are at work.

I bet Wozniak finally snapped and is doing this out of spite.
