So, at least the general principles of QM are correct. What this means is that there are non-local effects embedded in the theory, which make a deterministic (and thus predictable, i.e. non-random) description impossible.
No, not quite. It makes a local, deterministic description impossible. It does not make it impossible that the outcome of each measurement event was determined by the quantum wavefunction of the universe as a whole, only that it can't be predicted by a quantum wavefunction involving only the measured particles.
The further experiments done involve specifically tackling whether the quantum state of the detectors can explain the outcome of the experiment. This would remove the faster-than-light element of the paradox, since the detectors have been sitting there a sufficiently long time for any putative communication to travel between them and the particle source.
The latest experiment switches the state of the detectors using another quantum event using a single photon so that it is done randomly. This proves that the results of measurements cannot be predicted by a theory which doesn't include the quantum state of the switching photon. It does not prove that the universe as a whole is not governed by a deterministic wavefunction. In fact, to my mind, the more non-local the alternatives get, the more plausable it looks.
McAffee runs at high priority. Applications running at high priority are *supposed* to hog the CPU. How else can you ensure that critical applications can always run? McAffee needs to run at High to ensure it scans the files as soon as possible. There is nothing immature about this. I suspect you just don't have an on-access scanner on your Linux boxes, or you would discover that the problem is that on-access scanners are really invasive and CPU intensive, and is not to do with Windows.
If you want your builds in the background, drop the priority of DevStudio. Look for "start" in the help for how to do this when it runs, or use Task Manager to reduce it to BELOW_NORMAL.
"Because most of the applications we deal with have a GUI for configuration, we either need to do the equivilent of setting a DISPLAY variable or a remote desktop "
Since it is a server application, you could just separate out the configuration application from the server application. Like I do. Like MS does (Ever noticed how all the tools have a "Connect to Computer..." option?). Like everybody who knows what they are doing does. Invisible service with separate configuration application is The Microsoft Way. This is very easy to do.
Here are some strategies: * If it's a DB application, you can just have your application connect to the DB remotely, and edit the configuration there. * If the config is in files, any user with admin priveleges can access the files through the default shares \\$, which have access to local admin only. If you want other users to be able to administer the application, you can create a share for this purpose. ACLs can be used to secure the files and the share itself. * If configuration is in the registry, you can use the registry functions to access the remote registry. The user will be accessing the registry with their own credentials, so the Registry ACLs will only give them the same access they would have when logged on locally. * If you have a combination of the above configuration, use a combination of the strategies. * And of course you can use RPC or DCOM to provide a remote administration API, and connect to that. Just ensure you secure the object with the appropriate ACL. (No-one has access by default).
You don't look like you are a Microsoft sysadmin, or you would know * to use MSDN and Technet for documentation, with microsoft.* newsgroups on groups.google.com for the hard stuff, * to use SUS for patching, * to use NTBackup for backups, * that no MS application requires you to have administrative rights to use it, * to use Task manager to kill hung tasks. Yes, including explorer.exe. It's a bit like kill in Linux/unix. Give it a try.
Evidently since you need to have multiple users using consoles simultaneously (note, not processes running as different users, or users accessing the server under their own credentials) you have very specific needs, and I expect you are probably running a VAX with VT100 terminals.
And no, the tight coupling between the browser and the OS has very little to do with most security holes. They are just holes, with local code execution, and would be just as bad if the browser was not so integrated.
Firstly, AES is a symmetric cypher, and ECC is an asymmetric (public/private key) cypher. The comparison is between ECC and RSA.
Secondly, ECC is approximately as CPU intensive to implement as RSA for a given key length.
It is currently considered more secure, in that there are fewer known methods of speeding up solutions. However it is not clear that this is because it is intrinsically harder to solve, or because less effort has been spent on it.
Bruce Schneider, who I think is being referenced above, suggests using RSA with longer keys rather than ECC, since RSA is better understood, and you can have more confidence in RSA with a longer key than in ECC with a shorter key.
Unless, that is, memory or processor constraints mean that RSA with longer keys is not an option, in which case he suggests you might want to consider ECC.
Software is covered by first sale, even though you have to copy it in order to use it. This is because the United States Code contains a
specific exception for software users. The exception is:
Notwithstanding the provisions of section 106, it is not an infringement for the owner of a copy of a computer program to make or authorize the making of another copy or adaptation of that computer program provided:
(a) that such a new copy or adaptation is created as an essential step in the utilization of the computer program in conjunction with a machine and that it is used in no other manner
This means that you do not have to agree to the EULA in order to use the software, even though using the software involves making a copy. So just click past it.
People do fight over aluminium recycling. I remember when I was a kid, we used to collect milk-bottle tops and aluminium foil for a blindness charity.
Aluminium is one of the few things that make sense to sort and recycle; it's widespread, and it's expensive to produce, difficult to sort at the waste plant, and is destroyed by incineration.
Copper is also valuable, and people fight over recycling it, but the relevance to consumers is nearly zero since they see so little of it. When you rewire your house, the copper goes to a scrap merchant who separates and recycles it.
Iron/Steel doesn't need to be sorted by the consumer, because it can be done post-shredding/incineration.
Plastic bottles can be recycled profitably. Paper and glass about break even for the recycling company, and then only because the consumer has already sorted them, suggesting a net loss.
It happens less than it used to, but I have one client who lets auto updates run, and one patch in paticular (810577) has brought network browsing to a crawl.
In my experience this is almost always caused by network card autodetect not working right. Granted the patch may have broken this.
As my contribution to the user community, I suggest setting it manually to half duplex or full duplex, to see if either solves the problem.
what happens if a patch is bad and you suddenly have several thousand students show up screaming "your patch killed my machine with my term paper on it!"?
This happened to a friend of mine recently, only it was a hardware fault. The fact is that after fans, hard disks are the most failure-prone pice of equipment in the computer.
There is only one thing you can really do about this: Back it up.
If you are likely to be on the receiving end of the complaints, you may find it helpful to provide a backup service. It should consist of the following components:
A password-protected location on the University's servers for each user where they can store X MB of data of their choice.
Both Redundant storage and regular backups of same.
A policy for what users may store there.
An explanation of how to use the service, using, for example, NTBackup (free with XP) or similar software which is included with the operating system in question.
Agreement in principle from the faculty that tutors, administrative staff, or IT staff will assist in the backup process. (Automating it might be a project for a couple of first year CS students).
A document (electronic or otherwise) explaining all the above and making it clear that:
The university requires them to run certain software, including up-to-date patches and virus scanners. The university recommends other software, such as personal firewalls.
The backup service is available in case they have any problems, in particular problems related to software the university requires them to run, or recommends, but also other problems.
It is the student's responsibility to run backups. If the student has not backed up recently and a problem occurs for any reason it is their own responsibility.
They should ask their study partners tutors for assistance with the backup process if they don't understand it. Getting help is also their own responsibility.
Regular/occasional emails and paper memos reminding the student of these facts. Get the student newspaper involved: It's much better if they run an education campaign rather than criticise you afterwards for doing too little.
Remember, the more the student body is involved and empowered (euphemism for being told it is their own responsibility), the less you will have to do about it.
If you really want to over-egg the pudding you might even make versioned backups available, so they can find what they had six weeks ago -- might be useful for some.
It's not turnaround at all. Francophone Quebequois discriminating against Anglophone Quebequois is in no way a mirror image of English speaking canadians discriminating against speakers of other languages in other parts of the country. It's really simple: There are different people involved. That's like saying "some people over there are not being fair to some people who speaks the same language as me, so over here I'm not going to be fair to people who speak the same language as them". Why does that sound plausable to anyone??
To put it another way, If I punch some fellow (called Smith) on your street, and you smash the headlights of a fellow (called Jones) on my street, that's not turnaround, because Jones had nothing to do with my argument with Smith, and neither did you.
You are correct.
This omission appears as an explicit assumption in Professor Gold's "Paper".

I suspect Feynmann proposed this as an exercise, since the flaw is obvious to anyone with a degree in theoretical physics.
Flaw: Light is red-shifted climbing out of the gravity well. So when it reaches d2 there is not so much energy as when it left D1, so a smaller amount of mass will be produced. When it falls back down, the mass difference is equivalent to the kinetic energy gaind from falling by the equivalence relation E=mc^2.
"the total lack of regulation on the internet has led to a situation where anybody can say anything about anybody with no redress."
you say this as if it's a bad thing. seriously: so what? are people stupid enough to believe everything they read online? if so, well, serves 'em right.
So Alice posts something defamatory and untrue about Bob, Charlie reads it, and is stupid enought to believe it. Bob loses custom and therefore money.
According to you, it serves Bob right because Charlie is stupid.
The vast majority of the Windows 2000 administration tools can be used remotely. The GUI is not exported, the admin tool talks over the network to the server. That's why so many (all?) of them have "Connect Remote Server..." on the menu.
I don't know of any administrative tool shipped by Microsoft which can't operate remotely. You can do just about everything: Manage users and groups, kill processes, start and stop services, manage certificates, reboot the machine, create network shares, kill sessions etc...

It's a 3/4/5 triangle. So the width is 4/5 of the diagonal (16 inches) and the height is 3/5 of the diagonal (12 inches).

This is the sort of pedantry up with which I will not put!
If you lose a lot of work in Outlook or Word, it is because you have turned off the default auto-save behavior.
By default, you won't lose more than three minutes of work, and you can change that to less if you like.

This ignores the frequency shift due to the moving mirror. Proof falls down. Thermodynamics and conservation of momentum both still hold.
