It looks like the article is more of a "i came, I saw, I wrote" stuff than a properly well researched article. The major (only?) things the article keeps pointing out is the "Lack of applications" and "No company pushing it"
Linux for the desktop is another matter. Its wide-scale adoption is still treated
with skepticism by experts, who say that for consumer-level users, simply configuring
Linux to dial into an ISP (Internet service provider) is a challenge.
What about KDE and GNOME diallers? Both work great.
But what hampers Linux the most, according to analysts, is a lack of applications that
can run on the open source operating system.
I think what they mean is a lack of Microsoft Office Compatible applications. However, what about OpenOffice and StarOffice 6 (though there is a very brief mention)
"All the system vendors are pushing Linux on the server side, [but] there's really no
large company that is... pushing Linux on the desktop," Claybrook said.
Looks like Mandrake , RedHat et al. have been forgotten?
My primary research interest is scalability issues in peer-to-peer computing networks. Although P2P computing has existed for some time as a basis for network applications such as FTP, Telnet, instant messaging, ICQ, and Microsoft's MSN Messenger Service and NetMeeting, recently it has managed to capture a lot of attention.
Unless I am much mistaken (and has also been noted in previous posts) all the above mentioned are still CLIENT/SERVER models. Except maybe ICQ and MSN Messenger (and Yahoo messenger also, btw), that now auth with the server, and then communicate peer to peer.
Indeed, the sudden emergence of new applications like SETI@Home, Groove, Napster, mobile communications, and Gnutella is threatening to replace the traditional client-server architecture of the web and bring rise to a new era in personal computing.
I thought he just said that FTP, Telnet, etc. were peer to peer ? Also, is Seti@HOME a P2P App or a Client server model (which is a lot more likely, as there is a fixed (set of) entity(ies) that hands out the data to be computed.
My recent work has focused on Gnutella as a model of a purely distributed computing system. Gnutella allows users to share information by directly connecting to each other forming a high-level network.
High Level Network? What exactly is that supposed to be?
One of the biggest problems in analyzing performance of distributed computing networks such as Gnutella as a function of size, is that even simple protocols result in complex network interactions.
Huh? How so, can someone please care to explain? Agreed, there are a few more setup/terminate requests going around, but thats about it. (I've not analysed the actual packets of either gnutella like networks, nor IM networks, but I'm guessing here)
In order to gain a deeper understanding of the nature of those interactions, an accurate model of the system is needed. A first step toward such a model is understanding the topology of the network. To discover the topology of the Gnutella network, I have developed a distributed computing system using Java RMI. This program allows instances of Gnutella's topology to be obtained in constant time, an extremely important feature when studying a highly dynamic network such as Gnutella.
Am I missing something here? I would think that using Java RMI to distribute a code to a remote machine for execution would be required here. How can a program sitting at one place determine in constant time the instance of topology of the network? Looks like he used something similar to traceroute . In that case, however, how can the topology be retrieved in constant time?
This stuff could be VERY useful in near-tropical regions. like India for example, the temperature difference (in the more extreme parts ~25N) goes from 40deg C (in the daytime) to something like 10-15 at night. So this could also possibly be used to churn out far more power than the aussie counterpart, IF used correctly. This is specifically for regions that have a high temperature during day/night times, and a nice dry climate. Coastal regions wouldnt be of so much use for the simple reason that the temp. gradient obtained is not so large.
Spammers never needed email before to 'get the message out'. It's called Direct Marketing for snail mail. Buy a product once, you go in their database. Periodically, whenever some new 'deal' comes out, no matter what your fealings are on the store, they feel compelled to issue you out a letter/flyer/etc informing you of what great new products they have just for you!
Actually if you look at Snail mail and Email, it costs a lot more to send a snail mail (print it out onto flyers, use envelopes, put appropriate postage on the envelope (so that the whole deal looks appealing), and create mailing lables to send the whole thing to.
With Email, it just has to be addressed to a mailing list (or a spam software given a list of addresses) and the *ENTIRE* message is put out. The whole thing turns out to be at least 100 times chepaer (in terms of efficiency, money, everything).
Email spam is just more efficient, and therefore more far reaching.

Agreed. Another comment I'd like to add here is that the 8086 processor and related (that includes 8088, 80186/188) did not have the concepts of (a) Multi-tasking and (b) kernel space vs. user user space. Thats why the processor was so damn cheap, as compared to the others available "Out There".
So you should really be thrashing Intel for making a processor that did not support VM, Multitasking, Task Switching (Interrupts are just that, but a lame form) or kernel/user space differences. Not DOS. Dos was really cool, for the time it existed primarily.
However, Microsoft *SHOULD* have migrated to 32bit dos with the advent of the 386 processor from intel.

Well, I'd like to share a few thoughts on the demise of DOS...
First of all, I always used to use dos batch files to do fancy little things (like renaming 100s of JPG or GIF files into a neat little order), and get stuff to work. CDROM drivers, sound drivers, you name it. Loaded through DOS.
Second, when I wanted to remove all traces of WinNT from my machine, and install Win2k (at work), and I didnt have a boot disk! What could one do except delete everything manually (through the safe mode command prompt option), no deltree, no help from linux either (C: is NTFS). And doing a recursive ATTRIB -R -S -H -A * in all directories one at a time... couldnt have done it without DOS
Sad to see you go.... DOS always rox (esp. on the 8086 I learned using a PC on.... )
I've actually driven my bike (as in gas-powered, not muscle-powered) at 110kmph (little under 70mph) with my helmet visor UP, and there is ABSOLUTELY no problem with breathing, just that there is a lot of wind around you, and you gotta be DAMN careful.
Setting up the home network, however, has been a pain in the @ss! We need to rewire the coax, so I can have an office in the non-flood-prone area of the house, plus I am still in need of a router
You can get a single hub / switch / router that can plug into the cable modem's Ethernet port, and then do a UTP CAT5 wiring around the house. Much more convenient if you need to move your PCs around.
I miss the LAN, especially the two fast laser printers, my file shares and three machines of my own in different locations.
Why dont you try to VPN into your office, esp. when you have broadband internet access? Get help doing this from the sysads in your office, or do it yourself if possible.

I doubt it has anything to do with piracy. Its just that the DVD track density is MUCH higher than a normal CDROM/CDR. This requires the laser to be sharper and more powerful.
Some DVD Players CAN read CDR discs, while others cannot, probably due to the laser reflection problems from a normal CDR (it is not as reflective as the stamped CDROM).
Also, some DVD drives can DAMAGE CDR discs (which happened to one of my bootable installation CDROM after a lot of use in a friends DVD drive). However, not all discs seem to be damaged by a DVD, or are damaged to varying extents, probably due to manufacturing techniques used in the CDR disc.
the article on enews mentiones that they can also take on ASIC manufacturers and (any) other companies that make memory interfaces to "their" RAMs. i would rather like to see them take on nvidia rather than intel. that should turn out to be fun...
why not simply go back to the ol' days of EDO DRAM (or will someone else, maybe even Rambus claim patents forit???)
In the old days, Life was wild, rich, and largely litigation-free. geeks were real geeks, tech companies were real tech companies and litigators went down the drain... (Sorry Douglas Adams, i just had to...)
I think that flexi-time is not only a good idea, it is the way to go (esp. with software). How many of us really want to work 9pm - 5am and sleep the day through? and, besides, rather than having fixed workload (like 40-70hrs / week etc) we should be having flexible workloads, AS LONG AS we get the job done on time and properly. how does it matter if we finished the job in the last 3 days or in the first 3?
