Fiber channel just seems to have to high a cost of entry these days (or maybe it always have:-). It's not bad today with SATA being used on the storage arrays, but it is hard to compete with the other emerging standards. I've been using AoE for a little while now and have been impressed with the bang for the buck.
A GigE switch is cheap, and a GigE port is easy to add, or you can use the existing one on a system. AoE sits down below the IP stack so there is little overhead for comm, and it looks like a SATA drive in most ways. The primary vendor's appliance (www.coraid.com) will take a rack full of SATA and make it look like one drive via various RAID configs.
Yeah FC is faster, but how many drives are going to be talking at once? Are you really going to fill the GigE and need a FC to alleviate the bottleneck? If you are then FC is probably not the right solution for you anyway.
Your mileage may vary, but I expect anyone will get comparable results for the price, and many will get excellent results overall.
... to show everyone around you that you are stupid enough to pay $2.50 for a single song. For that price I want permanent/physical media atleast (5 songs would be $12.50 for a pretty lame CD). What percentage goes the artist? Is it even measurable?
Looks like it uses a Ca approach, so it is secure as long as you trust them. They go to great lengths to talk about their paranoia, but it doesn't all sound right (why talk about wooden blocks?).
They use RSA with a 2k key, and DSA with a 2k key. If they are that worried about DSA why not worry the same about RSA (1K DSA is probably stronger then 2k RSA). They use Elgamal, but don't talk about how they avoid the ciphers weaknesses (a problem the PGP community has struggled with for a long time).
Sounds like engineering towards executive summaries to me. They need to provide the protocol for public review before I spend any time using it.
we here in the US do require parity for a sane treatment of intellectual property. These inequities are unfair to the people damaged by them in each instance.
So for that reason we should adopt the UK model of expiring copyrights here in the US.
Think about it. You want to threaten the bad guys, who are a little less educated and a whole lot more guilable then you are. In that light you concoct a story that makes it sound like this database is being watched with "superhuman" effeciency by the head in each district. Throw in the part about tracking and non removable to make kidnapping seem dangerous, and you keep the officials safe on top of it.
This sounds like it is the high tech version of the "This is protected by an alarm system." sticker. Instead of just buying them and sticking them on your windows, you do a press conference.
Think about it. No one can make you legally bound for something they just send to you. A legal status such as copyright can be infered, but not much else. This is a typical legal tactic of bullying without much more then impressive verbage to stand behind.
Anyone ever estimate how much space these things are wasting on servers all over the US (I'm assuming this is unique to the US)?
Let's face it, any self respecting pirate will make a binary copy (bit for bit) of any digital media. Once you have the bits, no technology will limit the numbers of copies you make. They are targetting the little guy who makes a few copies, etiher under fair use or slightly beyond. Someone who just casually wants to make a copy, but isn't going to try really hard before shelling out for another CD.
This isn't about limitting piracy, but boosting sales. May seem the same thing, but in this case I don't think it is.
I'm so glad that resources are being used to protect valuable corporate IP instead of that icky war on terrorism. Maybe now my children can safely attend school to only hear and see legitimatly licensed content. One more thing I can sleep better about.
The average price per minute should drop as more lengthy works get included. I can't see them charging ten or twenty bucks for a full length work, and there has to be a minimum charge for the shorter ones.
If you ever loose a password for an Extreme Switch then you will find they have the same thing embedded in their gear. I took over a couple of large chasis type switches as part of a reorg, and I didn't have the password for either of them. When I called Extreme to get the reset procedure they insisted that I had to connect the switch to a modem or open Internet connection and let them reset the password using a secret system (read backdoor).
Needless to say I replaced the switches with something else that cost less then the next year's maintanence and have slept much better. The sad part is that Extreme sales guys never could understand why I was unhappy with that situation.
Marconi was much more of a craftsman and businessman than a scientist.
I think the above sums up a lot about Marconi and radio. He did little more then make the Hertzian spark gap generator acceptable for trans atlantic transmissions along with a practical receiver. The transmitter technology was so primitive/disruptive that is was banned later on.
Real radio came from a handful of other inventors who don't get much credit these days. Tesla did lots of work at the same time as Marconi on modulated carrier waves for radio (the method we use today).
He shouldn't hold the title "inventor of radio", but "inventor of the radio industry".
By keeping the DMCA and then giving special legistlative protection to individual industries (like the small mechanics and third party tool vendors in this case) we are bringing ourselves to a huge regulator nightmare quicker and quicker. By getting rid of the DMCA we could allow people to hack away at these problems and make a profitable industry that benefits us all.
I have been looking at the MM10 (the older version) as a small Linux computer for some months now and the memory was always a hold up. This things solves that and then some.
The older model was small and light, but very usable. You could confortably hold it in one hand for a long time and it never got warm/hot. This was the thinnest thing I've ever seen, and the smallest without seeming to sacrifice on usability (close to sacrifice though).
I might just have get one and see about running Linux on this little guy.
No, they weren't the first, but they really did push the bar up. Before that no other commercial post went out on that many newgroups and mailling list at the same time.
Of course that was also near the end of being able to retaliate by sending people copies of your generic OS kernel in the mail.
I miss the fronteir days before Al Gore paved a Interstate through the town called Internet:-).
The best part of the unit was the big button on the top of the keyboard. You hit it and it lights up green and says "3D". Oh so gaudy.
The display takes anywhere from one to 10 images to get used to, but it does work well. The lack of anti-glare coating can make usage in some orientations troublesome, but that can be overcome by moving the machine/user.
I want to know when Google is going to have more machines in their server famrs then all the other domains on the Internet put together? Having seen one of their installations (I don't think it was a big one either), it can't be far off. Then they should be able to Index the Internet:-).
That seems about the same stats as the EVDO card I've been using from verizon for months now. Basically it is a 3G CDMA-2000 add on that offers bursts to 2Mbps down. I reliably get 600Kbps down and 150 Kbps up. Then when your not in the DC or San Diego footprint you get 144 Kbps bursts up and down.
I thought 3G was dead (who needs any of these things in a phone, really), but EVDO (EVolution Data Only) convinced me this is what it is really for. When I'm stopped in traffic I can access the net. When I'm waiting for the girls to finnish shopping, I can access the net. And on, you get the idea. Hell, I'm even doing some video conferences over this card.
I was actually talking to a number of people at Dell before they made this decision. They were calling out into the customer base to find out why this was going on. The general consensus was that knowledgable people did not work well with low end call centers, and these same people make purchasing decisions.
Just as in any industry there are jobs that can be sent anywhere, and some that you need either high levels of expertise or a cultrual equivalence. These things will work themselves out over time. We might not like the results as a country, but it is not something we can control.
Because they are more often correct then Gartner. Of course neither would like you to know about the research outfit known as "Coin and Dice" which has a 20% higher accuracy rate in the last decade.
Honestly, these guys don't sell interest in their products without some splash. I've seen good work and bad work come out of the research industry. Unfortunatly, we tend to act more on the bad.
This is the same turmoil that hardware engineers went through for numerous years. When I completed my EE I realized that hardware (while very fulfilling) didn't pay as well as software. Western software engineering has become over inflated and expensive in the world market and we are going to see some pain.
Looking at history though, the cleaning of house will be OK in the long run. Some people will have to find new careers, but the pipeline of new people should also shrink somewhat. Look around you. How many of your co workers got into programming soley due to the money, or really don't have a love of it but of the paycheck. I think you will see the part of the 25% that won't come from reduced entries of new programmers.
These beasts are different from root servers (although many of the same entities run them). Many ISPs run one or more levels of caching DNS servers to reduce load and latency. This is where most of the caching would occur.
I understand he isn't running CD images through this (although someone can), but this could be abbusive to some DNS servers. I run two caching servers for about 45 users and we get around 50K requests in an hour. We need most of the 100 MB allocated to our dnscache to keep the hit ratio where it should be. I can't imagine what some TIER I DNS server might look like if this becomes prevalent.
A good DNS cache should still be useful, just not as much as it used to be. The reason, you will reference sites that you use (your mail server, popular websites) thousands of times, while you will access each block in the download once or twice. The hit count should wash out the noise to some degree. Now sites that you only hit once every few hours are likly to require smarter cache design to not become irrelevant to the cache.

And those same people often think violence is just fine for their children to watch. Having two kids myself I just can't fathom that mentality.
1)Real walls
2)Real door
3)Window/natural light
4)Controlable lighting
5)Do not Disturb button on the phone
6)Place for people to eat lunch together
