Spammers can still create new domains on a hit-and-run basis
Fortunately the whois data contains that date and time that the domain was created. Therefore, I can choose to refuse mail from recently created domains. Alternatively, this could be a springboard to domain-name reputation systems.
At the moment the domain name can't be trusted so I can't use these otherwise handy techniques.
You'd just get 100%-authenticated emails from 1stmortgageusa.biz and naturalviagra4u.com.
Excellent. Now I can get "100%-authenticated" whois data and...
o Use legal tools against the spammer o Blacklist by domain not IP o Refuse email from domains with a registration date less than X days ago oUse "domain reputation" services
At the moment I can't use any of these because I can't trust the sender information.
So God allows suffering because it causes us to turn to him? That's really not a healthy relationship, not even in a parent-child context. That's like secretly burning your kid's homework at the last minute so he has to beg you for help.
No, that's like allowing your child to make a mistake so that they learn from it (often far better than they ever would if you stopped them from making the mistake in the first place).
Why does disbelief in God warrant eternal suffering? Because he's smarter than me, and I wouldn't understand?
No, because as creator, he makes the rules. What God says is good is good and what he says is bad is bad. In our rebellion against God, we often think that there ought to be some arbitrator to whom God must submit. Sometimes we call it "morality". We do that because we don't like God's rules and we think that we've got a better set. However, because God created us, he knows the best possible set of rules and boundaries. Fortunately he has told us what those rules and boundaries are.
Furthermore, in his great love for us, he has sent his only son, Jesus Christ, to suffer and die in our place so that, by repenting and trusting in Christ, we may be forgiven for the times that we rebel against God.
Firstly, I'd be interested in seeing the biblical texts from which you conclude that God is all powerful and all loving. However, for now, let's assume that He is both of the above.
It is quite simple to show that an all powerful and all loving God can allow evil and suffering in this world.
Evil and suffering are not some sort of accident. They are part of God's plan. When everything is going well for us, it is easy to assume that we can do fine well without God - we grow complacent and reject God - even doubting that he exists. In contrast, when we suffer, we often turn to God looking for help. Since only those who believe in God and put their trust in his son Jesus Christ will be spared the eternal punishment of hell, it is far more loving for God to allow people to suffer now so that they turn to him and enjoy an eternity with him in heaven when they die.
I'm happy to continue this discussion and answer any further questions you may have but am aware that we are well off-topic. If you'd like to email me, you can do so - arr@dataconnection.com.
Even the most die hard christian fundamentalists would have a job believing so much patent bullcrap. Please, if you want to be christian then at least be one of the ones that whines "well, you ren't supposed to take it all litterally" every time you are challenged.
I'm a Christian and I believe it is literally true. Remember, the Bible believing Christian believes amongst other things that...
o God created the universe o God raised Jesus Christ from the dead
As an unbeliever, surely even you agree that causing the flood and enabling Noah to build the ark are trivial by comparison.
I never understood how quantum cryptography is not vulnerable to normal man in the middle attacks. Anyone care to explain?
What most people miss is the fact that there are two channels in quantum cryptography. First, there's the channel carrying the photons (which will become the secure channel following the safe transmission of a one-time pad). Next, there's the channel over which you verify that the one-time pad wasn't messed with. These two channels must not be the same otherwise the classic MITM attack works.
Furthermore, if an attacker can gain control over both channels then the MITM attack still works.
Few quantum crypto books bother to explain this and as a result, few people realise the problems. I predict that if quatum crypto reaches the masses then there will be a high-profile case or two involving this sort of attack before it's all sorted.
Please tell which vulnerability would screw all my properly made backups? By properly made backup I mean a backup that is made regulary to an external medium, like a tape or CDR, and is regulary verified to be readable.
The issue here is that a virus may slowly corrupt your data over a long period of time. If, like a great many people, you recycle backup tapes - eventually all your backups will also contain the corrupt data.
...and they probably won't bother. This whole "we'll give you $LOTS if you can crack this" is all a big con. They know fine well that nobody serious will take up the challenge. Then, in a few months/years time they say "hey look, nobody can crack it - must be really good".
Agreed -- which is why I insist to have the source code for every piece of software I run.
And how does that help you? Let's assume that you've got ~1,000,000 lines of code. Have you reviewed each one of them? The recent attempt to install a Linux backdoor was only spotted by 3 guys examining the code - and they were just concentrating on a few lines.
Having the source code yourself isn't really going to help. You have to put your trust in the developers or not run it at all.
You can't spoof sender IPs - not for a TCP session like that required for SMTP anyway.
(Well okay, it's not quite true. You could just about manage to spoof IPs for machines on the same ethernet segment as you. However, if you're on the same segment as an outbound mail server, you're probably allowed to send via that server anyway.)

By the time you spot it, perhaps it's too late.
