Only a few of my machines run Linux. A large number are older SGIs running SGI IRIX. The latest stock Apache 1.3.19 builds fine but is even slower than the bundled Netscape Fasttrack httpd server that comes with IRIX. 1.3.14 with the AAP patches is quite a bit faster, fastest httpd I've seen on my machines. I already have the hardware and software so I'll probably be sticking to SGI MIPS & IRIX for awhile. Guess I'll have to prod and poke at the 1.3.14 patches a bit longer to see if I can get them to like the 1.3.19 codebase.
I love my PowerBook and all, but this has got me kinda edgy. DVD is a pretty big thing and I can understand why the press is reporting this. What I want to know is how many seemingly little things wont make it in this first release. Something like ColorSync may be of little use to a home user, but graphic artists depend on it. How much else will be missing from the initial release? I'm sure DVD support isn't the only thing.
In a related note, I still can't help but think about Copland. At first it was most likely going to support even my IIfx (68030 @ 40 MHz). Then it was going to require a PowerMac. Then it was canceled. Rhapsody/OS X was announced and would probably require a PPC 603 or 604 Mac. Now it's going to require a G3.
BTW, I know that Copland != Rhapsody/OS X, but did ya know that Copland, even with debug code, used less than 8 MB RAM in the DR0 release?
I've got my old Mac 512K (1985) in the closet these days... pull it out every now and then to show off boot times. My MacWrite/MacPaint floppy (which also has a System Folder on it) boots to fully functional Finder (the Mac desktop) in about 7 seconds after the power switch is flicked on. Not too shabby.
You brought up some very interesting points. I wonder if anyone out there has been able to compare this display to other somewhat similar displays: Apple Cinema Display 22", scads of 20" 4:3 displays, etc...
And while you're at it, replace the Silicon Graphics cube logo with the new "sgi" logo. Sure, the cube logo was cooler, but it's long gone these days.

Perhaps if you don't consider the performance hit. From all of the figures I've seen, PHP is much faster than perl. Especially on websites. Mod_Perl does speed things up by a HUGE margin, but unfortunatly my company does not allow webservers other than Netscape/iPlanet Enterprise... so we must run our perl script CGIs the old fashioned slow way. If you know of any way around this, it would be of help! We do like perl!
Should we all quit our jobs too? I am willing to bet that over 50% of Slashdot readers from America are either sysadmins or coders, making six figures. To us, broadband is PART of our life and job.
Has anyone stopped to think about some of the expenses that the world's broadband providers have? Overpriced Cisco routers and switches (running Cisco IOS), overpriced NT and Solaris servers, overpriced HP NetVue management software, etc. Notice a common thread? Closed source.
Folks, we are giving these people OUR money... and they're spending it foolishly. This the the age where a company's OpenSource Strategy is just as important as their Business Plan. Yet these companies act as though they were in the dark ages. Why do we stand for this? Perhaps we try not to care or don't even know about it. Costs, reliablity, and scalability are all suffering because of the choices our major providers have been making. It has to come to an end.
There once was a time when the town barber was also the town surgeon. There was also a time when closed source projects fit the bill. It's time to move on, it's time that these companies using OUR MONEY join the opensource community and begin to enjoy and pass along the benefits.
I've recently seen some pretty big claims from CableTV providers talking about brining in 45+ Mbit access to subscriber home with an average thruput of over 20 Mbit. I belive MaximumPC Magazine even had an article on this. In my area we can only get ~4.5 Mbit cable, 1.5 Mbit SDSL, and 2.2 Mbit ADSL. What is available in other parts of the country? Anyone have experinece with *consumer* 20, 30, or even 40 Mbit broadband?
Are there any other crazy concepts for transmitting data faster than the speed of light? Perhaps something along the lines of the "Rope Trick" I suggested a few threads back?
It's easy for me to understand that particles themselves (in this case electromagnetic energy) cannot travel faster than the speed of light. Thus, the large amount of "lag" between Earth and Mars.
However, would it be possible to do something similar to the following poor example? If not, please explain.
1) String a rope between two points, one near Mars, one near Earth (yes, I realize the problems this would cause due to orbits and whatnot).
2) Rather than sending electromagnetic energy between the two points, simply "tug" on the rope. Rope only has to move a few millimeters rather than billions of miles.
Please note that I have never taken a physics class... and it shows.
...that more bandwidth-ignorant people aren't already wondering why Mars doesn't at least have a 2.0 Gbit/sec link since they themselves are able to get 4.5 Gbit/sec from their local cable company in Omaha, Nebraska.
Yep. 64-bit memory bus, just like your average PC or Mac. That's one of the reasons this model only costs $995. It's the "eMachines" of Sun's lineup. If you need mega-phat memory bitpath, buy a SunBlade 1000 or get a used Ultra 30 or Ultra 60.
Short of getting muliple OC192's from the same provider (good luck), there is almost NO WAY to get around having to spend $300 - $500 per megabit for access to a Tier 1 backbone provider (Sprintlink, UUNet, etc).
Say your ISP is in or near a major city and they can get a T3 or OC3 for $300 per megabit (155 x $300 = $46,500 per month). 155 Mbit, perfectly distributed and not oversold, can feed 103 1.5 Mbit DSL users. However, done that way, it's costing the ISP $450 per user per month. You're not going to see that happen. So, ISPs usually oversell by 10 - 20x, which will drop the per user bandwidth cost to, say, $45 at 10x overselling.
So, *excluding* their manpower, sysadmins, hardware costs, electricity, heating, cooling, tech support, etc --AND-- given that they can buy bandwidth at $400 per megabit, --AND-- given the gamble that at any moment, only 10% of their DSL users will be maxing out their connection, the ISP stil has to charge at least $45 per month per 1.5 Mbit DSL user. More likely it will cost at least $90 before they even -begin- to bring in a profit.
Peer to Peer filesharing is a Big Thing and is growing at a huge rate, they're no denying that. With Napster alone many people are finding their unattended PC using almost half of their DSL thruput at any given moment.
There is no free lunch, your ISP, no matter how well connected, can't create bandwidth from nothing. Regardless if you get 5 Mbit access via your cable modem or can overclock your Pentium 4 to 1.8 GHz.
You do have to put the filters on all your voice equipment as some (but not all) of them will interfere with the DSL.
Or do as I did... my POTS line come into a wiring closet in my home and directly into the DSL "modem". The filtered output from the modem then feeds the rest of the house. No need for a filter on each phone tap.

Abbott's clean 64-bit support is pretty nice too.
Has anyone managed to modify the latest Accelerating Apache Patches (1.3.14) to cleanly apply atop the Apache 1.3.19 source?

The heck with Pluto. I'd rather see them try to revive the X-33/X-34 Venturestar. The Spaceshuttle orbitors are getting a might bit crusty.

Maybe, maybe not.
Macs, even high-end G4 systems, do not yet offer ECC RAM support, nor are fully 64-bit addressable.
