"Spamtrap" is an email account set up only to receive spam mail. That email address is never given to any legitimate user.
So maybe they just setup spamtraps, then publish those email in some honey pot places where spammers scrape email addresses, et voila !
Of course, any emails sent to the spamtraps will be guaranteed to be spam. Now, the Marketing department steps in and says: Let's call this : "The concept of receiver reputation";-)
By the way, I already block way more than 99.9% of spam using the following, this was a one-time setup with no need for white/black listing maintenance:
-Spam Assassin
-Real time blacklists
-Greeting delays
-Rate control
-Max senders by message and other various sendmail option You can view the configuration
here.
-Priority 1 and Priority 10 mail servers are always down, Priority 5 mailservers are the real ones
-Spam trap addresses
It is so efficient that I didn't have to resort to graylisting yet but I could always use it to achieve even better results. I am not ready for the downsides of graylisting yet.
Since correctly using available open-source tools already gives better than 99.9% result (1 spam every 1000 forwarded message) I am not sure of the relevance of the advertised product;-)
Hehe... I know, apparently, some even ask if Pamela is a boy or a girl. I am thinking of setting up a web page with, say, ten pictures where people can vote on what they think Pamela looks like. Could be funny... I just found out now that PJ was a kind of anonymous way to publish stuff. Apparently she gives interviews. although !
Cheers,
Nice try but the rocks move (rotate) with the earth surface just like you are. In fact if the earth suddenly stopped to rotate, then the rocks (and yourself) would start to move quite a bit;-)
Also, if you throw a ball horizontally 500 feet in the air when there is no wind, it will fall on the same spot because even earth atmosphere rotate with it (at least when wind is at 0;-)
I use to use skype out a lot then I moved to install my own asterisk server. Long distance calls are much cheaper now, 1 cent a minute compared to 5 with skype out. I can connect to my server through the internet and the call quality is superior to skype, it matches PSTN quality.
I just wander how many skype users have moved to asterisk or other cheaper VOIP solutions. It might have contributed to skype downfall,

Hello ! this is me emitting radio signals from a 7 billion light years away planet, come and join me for dinner, what do you expect to find when you arrive, even if you could get there instantly ?;-))

This is another very stupid guy like me that doesn't use debuggers. When he does use them, it resembles quite strangely the usage I do when I DO use debuggers.
Let me know when you come up something that at least resembles a rationale for your bizarre bias against using a debugger for Java. Until then, I'll take you at face value and assume that it's a manifestation of your lack of confidence in your manhood -- or something like that.
I have absolutely no bias against people using a debugger. Where did you get that idea? I just said I rarely used one in my J2EE projects, so rarely that I don't even remember where it is in the menus. I jokingly stated "Real programmer don't use debuggers" as some kind of bragging, I could admit that. It's not my fault if you took it so seriously and that you seem to have decided to teach me a lesson about how stupid I was not to use a debugger.
Since I do not use a debugger that often, the functionality of it in eclipse is less important for me, that's all my post was about.
To make you happy, should I start using one and post back here telling you how great it is ?
Am I automatically an idiot because I do not use a debugger ?
Do you want to force me to use a debugger so you may then respect me ?
I won't ask you if you are jealous because I get away without a debugger given your former replies;-)
About my experience with debugging big and complex projects, I won't go there but I will give you a hint, look at the source code. The fact that you seem to want to challenge me about the size of projects I have worked on makes me suspect that you may not have worked on such big and complex projects. Otherwise, you wouldn't feel the need to challenge me on that.
Congratulations, you must be a real genius for having figured out how to use a debugger;-)
Read my other posts on this thread, I said I used debuggers mostly to reverse engineer code. I have used them mostly with assembly languages. With stack traces, log4g, the jvm being able to run in debug or trace mode itself, etc.. I do not need to use them with eclipse.
It doesn't take very long to learn how to use a debugger. Learning to code properly takes considerably longer. As a matter of fact, when you know how low level languages like assembly and machine languages work and that you are also familiar with the internals of the jvm, you don't even have to "learn" how to use a debugger, you just use it.
If being able to switch debug on the fly on a remote server is so important to you. Is that because you debug your programs while they are in production ? Note that, as another poster mentioned, it is perfectly feasible with log4j as well.
Thanks for your advice, I'll go buy myself debuggers for dummies.;-)
It could happen the day 95% of their customers agree that they have no problem getting voluntarily implanted.
To help, they could offer a 10% discount to all their loyal implanted customers to start with and when almost all their customers are implanted, require it to get into the store;-)
Are you telling me that in Germany, Portugal and Belgium, you have to carry your ID with you to go buy a loaf of bread, to go mountain biking, to go jogging, to go to the beach and heck while you are swimming ?;-) And that if you don't, you might get fined for it ?
Remember, states that have a law to force you to show ID on demand usually force you to have your "papers" with you all the time. Otherwise, it would be hard for them to enforce the law.
Of course, you have to show ID on demand in some situations and most modern states FORCE you to carry your driver license with you when you are driving but it is different than forcing you to carry your "papers" with you all the time like it is the case in some country.
I realise the US has a different history than most places, but in almost any country you want to name throughout most of the 20th and now 21st centuries, showing some kind of identification on demand by the local authorities is pretty standard stuff. This is also what he is
Where do you come from ? The only countries where you have to show ID on demand are police states. This is even a factor when categorizing states to tell whether or not they are police states. Remember USSR and how proud western countries where to live in free states ? USSR wasn't free because you had to show ID on demand. Where has all that rhetoric gone ?
This is more and more scary, as I keep reading this thread, I realize that more and more people think that they do have to show ID on demand without knowing what it implies.
Here in Canada, the police can arrest you for refusing to identify yourself. A driver's license does that, but any other way would work. You must have a similar law down there, too. It sounds like the guy was being a jerk, and the cop used that excuse.
I live in Canada and this is completely false. Having to show ID equals police state. This is getting scary when Canadians citizen believe that they must show their ID if asked for it and that they post such misinformation on/.
There is 3 important notions in laws. The spirit, the letter, and the application. All police forces and other legal administration employees work in the third category. The way things work out, we sometimes see abuse in the application and sometimes, on the contrary, law enforcement agencies do not care to enforce a given law.
I assume both the police and the store reps though they were doing the right thing. That's why there is movements defending citizen rights and things like YRO. If it wasn't for them, the people responsible to apply and administer the law could basically do whatever they seem suited for them.
One thing people that apply the law do not like, it's a normal citizen remembering them that what they do is illegal. It's the old mentality where if you have done nothing wrong, you have nothing to fear, so you should be willing to allow any people responsible to apply the law to search you, ask for your receipt, your ID, etc..
I'm fond of the log4j library. Set it up, then litter your code with log statements - logger.error for...
Exactly;-)
But do not litter your code to much since it might affect performance if you really over do it. We usually comment off seldom used debug log statements and even delete them from the code once a one time fix has been applied to a weird bug that doesn't have many chances of showing its ugly face again.
Used according to standards and best practices, unused log4j statements ( when debug is set to off) won't affect performance much (maybe 1 or 2 %).
Log4j affects performance because even if you set debug=off, there is still one method call to check that the flag is off for every debug log statement. Try at least to comment off log4j debug log statements in computational loops;-)
Of course, you have to be in pretty good control of your code, plan and visualize in advance, before you actually start to write the code so the few times where you will need to write debugging statements is when you made some typing mistake (or almost).
It is a different approach to coding, but it leads to more robust code in my humble opinion. The down side of a debugger is that sometimes, it happens that some developers do not know what they are doing, they start writing code without prior planning and they manage to finally get it to work with the debugger. Typical time consumption ratio will be like 20% for writing the code and 80% to debug it and some bugs will go undetected.
My old way to do things is 50% planning before starting to code, 45% coding, 5% debugging. So the availability of a debugger is less important.
Note that I DO use debuggers if I need to reverse engineer code.
Again, I realize and I know that a debugger has become a standard tool in modern development teams. I am just saying I do not use them often so it is possible to get away without them.

Yep, it usually goes something like : "If the officer has reasonable reasons to believe that you have just committed an infraction"
I have never read the part where you "have to match the description of a suspect" although it might qualify as a sufficient reason ;-)))
