I was in a hotel that offered internet access through a CAT5 jack, but you had to go to a web page to "pay" for your session before you could get on the internet. This would make a great addition to a "free" shop in that you could hand out 30 minutes of access with a code printed on the receipt. If you need more access, buy another coffee. Any ideas how this could be implemented? Is it just a bastardized version of Apache, or something more integrated since it would need to intercept ALL outbound traffic?
Lol! The netatalk documentation doesn't mention anything about it. Seems like that would be a good thing to add in there somewhere. Thanks for the tip.
When it works, it works; when it fails, it fails disastrously.
Be careful with your FUD machine, you might break it. I can say/exactly/ the same thing about Linux - when it breaks, there are a thousand different places that you have to go hunting to try to find out what's fucked up. Just because you know linux better than you know Windows doesn't mean Windows is a piece of shit. I could make the same argument against linux, but I choose not to since I know there are ways to fix things that are broken, just as there are in Windows.
Actually it works/extremely/ well. Not only that, but NetApp and Oracle are buddy-buddy, so it is a fully-supported installation. Oracle doesn't care where the files are located, it just cares that the file can be open and accessed with stock file-system calls.
I just installed a Network ApplianceFAS250 in my server room.
It speaks CIFS, NFS, and iSCSI.
By the way, you're wrong... Oracle will run perfectly using CIFS shares (I'm running it now, and have been for the past few months), and NetApp has
plentyofdocuments in their tech library showing all the different ways to use attached storage with Oracle and many other pieces of software.
With respect to speed, it really depends on the network infrastructure. I've got a Cisco GigE switch attaching 6 machines directly to a GigE port on the NetApp Filer. It is literally twice as fast than the directly attached RAID 5 (caching, etc.) arrays that it replaced.
I think that Microsoft Exchange can be installed to a CIFS share, but if not, you should look at iSCSI. My company uses Lotus Notes 4.6.7 (sweet, merciful Christ, please put me out of my misery), and it works great from a CIFS share on the NetApp.
Microsoft has a free iSCSI Initiator for Windows that will mount an iSCSI device just like any other SCSI drive in Windows. You can find several iSCSI targets for linux here.
I have about 50 Mac's on our network (graphics department) that needed to talk with the new filer. Instead of installing a klugy piece of software to make the OS9 Macs talk to the SAN at $150/seat, I installed a linux box using samba to talk to the SAN through CIFS and netatalk (AppleTalk for linux) to re-share out the samba mounts.
Becides some quirks (Mac's don't see the linux gateway in the AFP browse list, but can connect directly through IP), it works rather well.
Look at iSCSI, it does exactly what you're looking for.

One of the first things IBM tried after inventing the relational database was to replace the file system with it. You can tell how far that went.
What do you mean? To this day IBM uses a database AS the filesystem in the AS/400. Ever heard of DB/2?
It was called Starlite. Our boys over at Cornell had a discussion on this back in '96. There's a pretty good debunking in response to the original question. Turns out that this is a very easy experiment to do, given controlled situations... I'm surprised The Discovery Channel couldn't find this.
Most companies would much rather spend a couple million to make the license problem go away then have to release any intellectual property.
And Linksys can spend far, far less to just rip out linux, and use another OS.
Let's say Linksys would replace the firmware with code derived from, oh, say BSD or QNX. Specifically, under a license that is not the GPL.
Should Linksys/still/ be required to give out the source code to the original firmware since they have products in the marketplace (peoples' homes) that are currently using that software, i.e. with older firmware?
If so, then does this parallel the current "hot topic" of conversation where SCO demands payment for linux code even though the offending code has been removed, simply because the code is still in use on unpatched servers?
IMHO, neither 'side' (MS, Oracle, etc. on one side and Linux, OpenOffice, MySQL etc. on the other) should really focus on 'winning'. Keep those core users, go after the others. MS is gradually learning to be competitive instead of anti-competitive, something that will benefit both sides in the long run.
Sir, I have to compliment you on this statement. With the sludge of comments on/., this one really shines.
"Ofcourse I expect them to have improved it since then, and if thay arn't going to introduce it on the market untill 2005 I guess it comes with a built in coffe machine by then..."
No, it's electronic. It will come with a small camera built in so you can take crappy, low-resolution pictures and print them off in black and white, or email them to all your friends.
Not quite. RAID 4 (n + 1) stripes data across the disks and writes a parity block in line with the block on the parity disk. RAID 5 cycles the parity block among all the n + 1 disks. Mirrored RAID 5 is two RAID 5 volumes mirrored to each other. RAID 6 writes two parity blocks on two different drives in the set. RAID 5 can withstand one drive failure. RAID 6 can withstand two drive failures. Mirrored RAID 5 can withstand an entire array of drives failing, but costs more in terms of total number of disks.
Oh, come on, that's no fun. We used to go into Best Buy and others of the like. On the computers, we'd pop up a command prompt and type the following...
del command.com debug a100 mov ax,40 mov ds,ax mov word ptr [1234], 72 jmp ffff:0000 [CR] rcx 10 n command.com w q exit
For those of you kiddies, this replaces the command processor with a program that reboots the computer. It was so fun just to leave it and go away. The next time the computer is rebooted, it magically continues rebooting itself. You can't break out of it without a startup floppy.
The costs involved with the hardware (tut systems) was pretty substantial. The owner of the property whent ahead with a MUCH simpler plan (I recommended) of putting a simple 24-port switch in the basement of each dwelling (24 room units) and daisy-chaining the switches together with 100MB fiber. We had to run CAT5 to each unit, but the costs of that (less than $100/drop) were cheaper than a TUT Systems client device (around $165) for each unit. In the end, we had one switch plugged into an upstream carrier. Turning on or off the units' internet access was as easy as telnetting to the switch and shutting down the port.
The 100MB was MORE than enough for the 1.5MB internet pipe, and as an added bonus the dwellings could game with each other on a true 100MB LAN!
Slashdot Mirror
I was planning an update to our global network to convert from RIP to OSPF so we could do some trivial load balancing.
Step 1: I telnetted into our core router and turned off RIP.
Step 2: Turn on OSPF.
The problem was that turning off RIP first killed all of our traffic world-wide. Oops. 10 seconds later OSPF brought the network back up. Sigh.
So which one is right?

Check out RemObjects. It's really a brilliant piece of software and is the first RPC development system I've used that's been a real joy to work with.

What you're asking for is a SAN.

Oracle has database links.
Create a database link (for example to an AS400) and you can query the remote tables just like local tables.
select * from somelib.sometable@as400
Oracle will pass as much SQL as it can to the remote DB engine in order to keep things speedy.
