Comment Too big to block (Score 1) 217

I run a small ISP and have several email servers I maintain. What I have observed is a hair trigger on the part of the large networks like Comcast. Even a few spam complaints is enough to get you black listed. It's hard to run a 100% perfectly clean server as you must to some degree trust your users. 1 malware infection on one of their machines sending spam and boom your cooked.

I have taken to telling customers that have issues sending to Comcast, AT&T, etc to get a Gmail account to send to these. No matter how much SPAM these servers send out they would never get listed as this would cause mass complaints from their users.

Comment Turbo charge my 4.77MHz PC (Score 1) 251

Way back in 1984 I discovered that as long as you were using a monochrome text or graphics adapter (Hercules) you could replace the 14.318MHz crystal with a higher frequency ( I think I got as high as 22MHz for 7.33MHz CPU clock). The software clock would run fast, but it was worth it for the speed boost. About 9 months later companies started offering turbo mother boards that would operate at 4.77MHz or 8MHz switch-able.

This would be fairly easy to produce. VHF radios are available cheap (Wouxen, Baofeng). Getting WIFI throughput would be all but impossible due to the necessity of using a much narrower than the 20 MHz channel WIFI uses at 2.4GHz.

Hams have been transmitting digital packets via radio over much father distances for over two decades. True it was only 1200 baud but I could see much higher speeds with much more modern DSP capabilities.

More than likely they cancelled this due to potential liability issues.

Comment SMTP (Score 1) 595

I don't think I will live long enough (I'm 55) to see this happen. SMTP is poorly designed from a modern security standpoint with spammers running amok for years now without a decent solution in sight. Can't get rid of it because so many use it. IPV4 replacement will be much harder.

Comment Lexmark case (Score 3, Insightful) 649

Printer manufacturers tried this several years ago with chips in ink cartridges. The supreme court ruled it was ok to reverse engineer the code on these chips if it was required to allow other companies to make make compatible cartidges. I would think the same would apply to cars and after market parts and upgrades.

You don't have to know how the computer works, just how to work the computer.
