Ever since Yahoo started putting up Macromedia advertisements without a simple STOP button on it, (blinky,flashing,dashing,wiggling,zooming,can't make it stop distractions) I yanked out Macromedia from the machine. When a right click on an unwanted possibly noisy advertisement doesn't bring up the play, loop, rewind, forward options, it's broken. I operate my computer. Programs that won't properly shut down when requested are out of control and not to be trusted.
Until Macromedia is more interested in end users than advertisers and other force feed content creaters, flash stays off my machine.
Worse, your method will not detect technician@mail0001, technician@mail0002, technician@mail0003, etc. because each server only sees one attempt.
Wrong...
The gateway router to the ISP's server farm would see the attempts and block the attacker very quickly protecting all the mailervers wether they are seprate machines or virtual machines in a cluster.
Let's face it. trying to email angel22@hotmail.com has a good chance of hitting a valid box simply due to the number of accounts. Your chances are much less if the server is limited to about 5000 accounts.
technician@mail3275.msn.com is no harder to hit than technician3275@msn.com.
You missed the point. An ISP with 500,000 users won't notice a 10 trys per minute attack. An ISP with only 5000 users per mailserver will quickly find the attack from the background noise and quickly stop the attack. technician 3275@MEGA.ISP would ignore a few fishings for bob, bob1 bob2 etc. There is also a great chance of a hit. However trying technician@mail0001, technician@mail0002, technician@mail0003 would provide a very bad hit rate expecially if each server hosted no more than about 5000 users mailboxes. The many bad guesses would trip the trigger and block the attacking server. It works on the principle of many electronic safe locks. 3 wrong trys and the combo is inop for like several hours to a day. It slows down the success of a brute force attack by blocking all access for a while. A 10 guess per minute attack simply would take many centuries instead of an day. It's the same security applied to mailservers. Few valid combinations, bad attempts lock out the user from trying for a while.
I should have full control over running my own email server
No problem. Most non-profit/amatuer/hobbiest servers I see have less than 5000 users. I have no problem with small ISP's providing e-mail. They provide poor yeild to a dictionary attack.
I could not afford an extra $500/mo or $6000 per year just for the right to send out email notices to users.
Would the law apply overseas? I could see lots of people abandoning MSN, Hotmail, & Yahoo mail to use overseas mail services. Would they be able to tax you if you went to the off shore mail server and sent from your account there? What's to keep a spammer from doing the same thing?
I got my first e-mail account while overseas. It's still my primary account. The ISP is a small one so it isn't the target of dictionary attacks like the US nationwide ISP's. After 8 years of use, it seldom gets more than 3 SPAM's per week. It's the main reason I keep it.
I think one of the things that is overlooked in reducing the success of dictionary attacks is what mega ISP's can do. They need to divide up their mail servers so each would have no more than say about 5000 mailboxes. It would make the addresses a little longer maybe. Instead of having an address such as technician126@msn.com, I would have an address like technician@mail3275.msn.com. A Mega ISP is a sitting duck for a dictionary attack. A dictionary attack on a small domain could easly be detected and rejected. As an example, more than 5 invalid emails from one TCP address in a day would block the sender for like a week. Attacks like bob@ bob1@ bob2@ bob3@... would quickly blacklist the sender for all of the ISP's inboxes, not just the server being attacked (@mail3275.msn.com would also block @mail****.msn.com). The inboxes would be protected by a virtual minefield. The spam failure rate would be high and the valid mail would not be impeded as a valid address is already known to the sender.
(disclaimer not my real addresses. I'm a member of a small ISP, not a national)
It's simple. Don't tax the sender. Tax the receiver, just like cell phone text spam the receiver pays. It's the quickest way to kill e-mail I know of. No in-boxes, no spam!
Something that is immune to unsolicited incomming messages (white list based) would replace E-mail as we know it. It would be a lot like IM buddy lists. E-mail is drowning in noise anyway. A white list filter would go a long way to killing most spam. People would opt for these things if UCE cost the receivers a bunch. Many folks are getting cell phones without text messaging simply due to the extra cost of receiving unwanted messages.
Maybe they can have enough clout to get past the DRM restrictions that keep me from playing the stuff in my car. My in dash MP3 player so far is incompatible with everyone else's offerings.
However since they push the WMA DRM'ed format, I doubt it.
They can sell bottled water by advertising it's quality over the run of the mill tap water.
Who will sell high quality MP3's that are better than lawsuit vunerable internet MP3's?
It makes as much sense as selling 8 track tapes because nobody has the stuff to copy them. It's high cost, not compatible with current generation devices (sure you need to buy new portable devices and in-dash units yada-yada NOT!) just to keep away from a de-facto standard format. Who can't play MP3's? Heck even my DVD player in the living room will play MP3's. There is no other format that will play in my car, portable, living room, etc. Too bad the industry is bent on not meeting the consumer demand.
Another player enters the market and has to buy content from someone else. They must apply DRM. No big deal unless they are big enough to negotiate a volume discount and can under price the competitors and make a profit. The other game is if they are big enough to replace the labels and contract their own content. At this point it's another same thing.
Wake me up if they break the RIAA business model of high prices and lots of DRM. Otherwise it's nothing new.
Unfortunatly, Hydrogen is a gas that is very flamable (burns good) over a very wide mix. Many other gasses are much more picky over the mix ratio. Here is a quick experiment. Mix hydrogen and air in a balloon. Mix Propane and air in a balloon. Which mixture has the greatest chance of being an explosive mixture? Hint check the LEL and UEL for both gasses. (Lower Explosive Level & Upper Explosive Level) Thats why car batteries explode more often than propane bbq's. To get a Propane Air mixture to explode in a balloon, the tolorable mix ratio is pretty tight. That is why propane is such a hard fuel to use in spugguns. A proper mix is hard to get.
Unfortunatly, that will leave many people out of music entirely. If music beomes a mono-culture, then by that standard, diversity dies. The religeous folks are not interested in Eminem even though he is on the top of the file trading list. Not everyone is interested in derogatory foul language rap. Fine, the Reality TV / shock TV crowd may buy it for a while, but as they mature, there will be interest in other music. Let's face it, just how much George Carlin type humor do you buy? Eminem is just this year's pet rock/cabbage patch/furby/etc. The novelty of the trash talk does wear off. Just because he is the top traded item doesn't mean the market will bear 150 copy cat artists any more than pet rocks expanded into other pet items like pet golf balls, pet lolly pops, pet turtles, etc. Trash rap is a novelty. Don't expect following acts to have the same popularity.
Just for grins, If you have a FRY's near you, take your flashlight to the store and compare it directly with the highly advertised Forever Flashlight and let me know if you get different results than I have. Of intrest is brightness, beam size, time of bright output, etc.
In other words, would you consider using the Forever Flashlight in place of one of the battery LED flashlights? The single AAA cell Dorcy I have has an aluminum body with 0-rings at both ends, but the push switch is not watertight, a weak spot in an otherwise fine very compact light.
I don't use a regular flashlight due to the low use time, breakable bulbs and the need for spare batteries. The Eveready LED folding lantern is a small brother to the florescent folding lantern. Great for reading and lighting the entire inside of a tent. 200 hours of light means a spare set of AA's is just insurancen not a nessacity. If you want a tiny spot of light like the Forever Flashlight provides, the Brinkman long life LED light runs on 2 AA batteries. I like to see more than just a spot, so I haven't ever changed it's batteries yet. It's useful for looking for signs in the dark where a wide pattern light won't reach the distance. The brinkman is about the size of a AA maglight and is waterproof. The Inova X5 is just about industructable, weather tight and the brightest of my LED lights, but is the most expensive to feed. It uses 2 camera lithium cells so a battery change is about $12. The CampCo 3 LED torch uses 3 regular AAA batteries and feels light and breakable like the forever flashlight. It works OK, but it seems lightweight and flimsy. The Coast TechTorches are a good personal light complete with belt carrying case and screw on diffuser. They put out a lot of light in a small size, but they use N cells so they are ot the cheapest to run, but they are much cheaper to use than the Inova. So in a nutshell, I use the Eveready the most in the tent and home for book reading. I use the Inova for daily use because of the brightness and it fits nicely in the Mag Light belt pouch. I keep a Brinkman in the car glovebox as a standby and the CampCo by the bed for the trip down the hall in the middle of the night.
Fry's has the Forever light on it's shelves. I tried one. It puts out much less light then any of the above lights. With it's lense, it has a small light pattern like the Brinkman. With the Brinkman I get hundreds of hours of brighter light without having to shake it and it's much smaller. The AA batteries are not hard to find. Most of the time I want a wider pattern to light a bigger spot than my footprint size spot on the ground.
It's simple really. One team has lots of experiance and is in tip top shape from the massive training they received. The other team is slower. They get woken up once in a great while to fix a problem. It's simple to note the fully mobilized team would have a faster responce team. They have response finely honed by experiance now.
Am I missing something. DTV and HDTV are related. Not all Digital TV broadcasts have to be High Definition. In non HDTV format DTV can have 4 seprate programs on one channel. The evening news doesn't have to be HDTV. However I think the broadcast flag applies to DTV as well to HDTV content.
This ruling eliminates any kind of non-authorized content, weither that is indie films, home movies, pirate TV stations, or illegal downloads.
Sure it will be playable by most everyone. The Internet just got a big jump past television by this. It just means that television just bacame a closed propritary format just like the Circuit City DIVIX. Now the good stuff is on the Internet. TV will have to do something drastic to get the eyeballs back like tax internet access to death.
If viewers are getting rips off the Internet instead of subscribing, the same problem exists.
They have the right to control their content. Fine, but doing something else on the Internet has the same result. Could be Slashdot, RPG's, comics, news, sports, indi music, etc. The same result is I'm not watching their content on the network. It's not illegal to do something else besides watch TV (yet anyhow).
When are they going to get it. You don't get eyeballs if your content can't compete with other content. They have to produce good stuff that I'll want to watch. Then they will have to let me know about it so I'll want to look for it. They will have to have affordable receivers for the content. (No existing 20-27 inch receivers, lots of monitors that will take an external tuner) I'm not spending $400 for a tuner and a simular chunk of change for a monitor to replace the under $150 television receiver to watch the evening news. There is so much trash on broadcast TV now, I don't bother. I get the news off the internet. I wouldn't know if something entertaining did come on. I have no idea what's on anymore. TV has been replaced by VHS, DVD's and Internet. Making TV user unfriendly is only going to accelerate this trend.
Have you ever tried one of those forever flashlights? Better off to get a LED flashlight that runs of 2 or 3 AA's. If your not currently shaking it, it's sorta like trying to navigate in the dark by the light from your luminous watch dial. These are far from bright enough to be usefull. Next time you are camping, look to see if anyone is using one to run to the bathroom at night. They are a very limited application device like placed next to the fuse box so you can see what tripped. It won't have a dead battery after 10 years of non-use. For everyting else, I use a light that is bright enough to use.
The licensed Compact Disk logo owned by Philips indicates the disk is formatted to a defined standard guranteeing compatibility. DRM does not meet the Compact Disk standard and does not have the licensed Compact Disk logo. I imediatly RIP all CD's. I don't put multiple hundreds of dollars of originals parked by the curb for someone to whisk away elsewhere. I would certanly know right away if I got a "Defective" CD as they are designed to either autorun a program (disabled) and / or not rip properly. Defective disks are promply exchanged. So far I haven't found any DRM disks displaying the Compact Disk tm. logo.
I have a Toyota Prius. There are only 2 aftermarket CD players that fit and interface to the multifunction display. A Pioneer and a Kenwood. Both do MP3's. Neither does Real Audio, WMA, any streaming format etc. It's the unsuported formats I can't use. I use MP3's because it is the defacto standard. My computer easly rips to that format. Winamp plays them fine. It's the single format that works with everyting. No other format can make that claim.
Many of those players that will play WMA files, WON'T play DRM WMA files. This is often overlooked. The PC can deal with the certificates or whatever it uses, but the stand alone shiny disk player can't transfer the keys from the PC. Therfore it won't play the Encrypted WMA files. Otherwise it would be simple to share the files with your favorite sharing service, burn them on CD's and play them in your DVD player. It's designed to not do this.
It should play stuff you rip yourself from non DRM sources into the WMA format.
Your DRM'ed WMA file can only be transfered to a portable device by a 2 way comm link. A one way link (Burn CD, play it in another device) is not supported.

So why didn't you write me back last week about the User Friendly cruise. Are you going or not?

I think your friends flashlight must be a real wimp. I just found a review of the Forever Flashlight that repeats my findings. It is dim.
The review can be found at http://www.equipped.com/led_lights2.htm#hds
I'll take a set of AA 200 hour batteries rather than mess with the constant shaking required to get marginal light from a Forever Flashlight
.
Just for grins, If you have a FRY's near you, take your flashlight to the store and compare it directly with the highly advertised Forever Flashlight and let me know if you get different results than I have. Of intrest is brightness, beam size, time of bright output, etc.
