I've been using AMD64 on a number of my servers for over a year and they kick butt! Especially for cryptography where one gets a order of magitude increase in preformance in RSA compared to x86 running at the same clock speed.
Considering the limitations of 32bit systems, including only 2-3GB of addressable memory, why doesn't apple move to a 64bit platform now and avoid future headaches later?
Besides, I heard that Intel also make 64bit AMD64 compatible CPU's as well.
Great, I will be leaving for a business trip soon, and now I can freely *access* those commercial WEP enabled Wi/Fi access points in many airports without risking my credit card.
Seriously though, Wi/Fi has to be treated like an unsecure public network, and anyone wants to restrict access they should use a more secure protocol like IPSec in host-to-host mode. Do not count on Wi/Fi manufactures to protect you, for some reason they just simply refuse to provide secure products.
I have to travel to Asia in a couple of weeks and urgently need to buy & configure a very small, yet powerful 64 bit server to take with me that can generate hundreds of digital signatures per second with RSA private keys. I need to fit this server in a small backpack to take with me onto a plane as carry-on. So far the best that I can find is the Shuttle SN95G5 which supports the AMD64 socket 939. Does anyone have any better (faster, smaller, or cheaper) alternatives to the shuttle? As a server, I will be running NetBSD on it, likely headless or with just a 80x25 text console, so I don't care about video or audio, but USB2.0 would be nice. And as a server, stability/reliability is critical. Alternatively, if anyone know of any PCI cards that can do hardware accelerated RSA with NetBSD or OpenBSD support, please let me know, since I can put that in a smaller/cheaper Mini-ITX case. Any advice is greatly appreciated. Thanks in advance. Alicia.
When my old Lexmark Optra EP postscript 600dpi laser printer ran out of toner, I noticed that it cost approx. (CAD)$90 to buy a replacement. This is too expensive, when I can buy a used Lexmark Optra LX+ postscript 1200dpi laser with a higher resolution and a larger and full toner cartridge for only (CAD)$120, although the LX+ is a huge and noisy beast compared to my small EP.
Anyways, since I had 3 empty laser toner cartridges, which have removeable soft plastic stoppers to the toner reservor, I thought, why not refill them myself? After all, people with inkjets typically use refill kits, so why not just buy the laser toner powder. Well it took a while, but I managed to find a shop in Toronto that sold bottles of the black laser toner powder specific to my printer. (Different types of laser printers may have fusers, which melt toner, set at different temperature, so one has to make sure to get the toner powder that is proper for their printer.)
These bottles of laser toner powder come in a case of 10 for less than (CAD)$80, with each bottle containing 85g of black powder which will fill up a toner cartridge to the brim for less than (CAD)$8 each. Since it was raining outside, I took a funnel and refilled 3 of my empty cartridges in the bathtub in case of spills. And not only was it quick and easy, without any mess, my refilled cartridges print just like new. And since I bought the case of 10 bottles, I can print all I want for several years without worring about toner.:-)
