While the 2.4 releases are (barely) newsworthy, why this? Are some people still using the _latest_ 2.2 kernels? Is there a reason to update to 2.2.x if you can't go 2.4 for some reason?
There is! I just setup a permanent IPSEC tunnel with freeswan and, for one of the boxes, which has an AMI MegaRAID controller, 2.4 simply _wont_ see the partition table (it sees the scsi ID, but that's it). After fighting with it for 6 hours, I just grabbed a 2.2.22, patched it with FreeS/WAN and here it is, humming quietly as it does its job.
(And of course the next day 2.2.23 comes out. Argh.)
just why did you feel compelled to tell us that - I mean, wouldn't we've just -know- who she is, and where's she's from, etc.?
Well, for the sake of completeness, I imagine, and also because Italy is such a small place. So, she's famous over here, but she's probably unknown in the rest of the world.
I've worked on a Mid-2001 online concert featuring the return of a very famous Italian, singer, Mina. The event was available in multicast for people connected to Italian ISPs Inwind and Libero/IOL/Infostrada (totalling around 7 - 8 million subscribers), Unicast for others. I personally configured the front-end routers with the PIM Rendez-vous point:-)
ISPs have merged, pages have changed, but by chance the concert page is still up, although it's in Italian.
Now, I'm working @ a Satellite ISP and we're streaming Multicast all the time (both windows media streams and a data-push protocol which needs no return channel (carousel + heavy FEC)).
Multicast dead? *not quite*
I'm also about to multicast-stream TV off 802.11b at my house just to see how it works!
P.S. By the way, I'd HAPPILY kick the last Microsoft boxes out of my server room. Does anybody know of a multicast acquisition-streaming platform which could be a drop-in replacement for Windows Media Encoders + Windows Media Server? Must work with Windows Media Player on the other side!
Recently they brought fiber to my house, with a little permanent gateway which gives me 3 10Mbps ports plus a POTS for voip.
The guy insisted on having me insert the CD into the drive, which will then auto-run and open a welcome window with everything I need to know. For the first 45 seconds I tried telling him that being a Linux box (and without a graphic card at all!) I was very very skeptic about the procedure:-)
Then, since it was pointless to try and introduce him to the unix world in 10 minutes, I just tried a "dhcpcd eth1" and voila!, I signed the acceptance form as if he did everything and sent him away.
But if he would prove to be really really stubborn I would have just let him install whatever he wanted on a spare PC just to reghost it 2 minutes later:-)
So they can triangulate on you and determine the position up to one meter, but from what range? The 802.11b network at my school fails after 50 feet.
?? If you are within range, you can connect, but you can be tracked (and thus expelled if intruding). If you are outside range, you can't be tracked, but you CAN'T CONNECT EITHER.
So the idea holds true regardless of the range!

It took me all of 30 seconds to enable 128 bit WEP and create a key on my new Linksys 802.11b router. Honestly, how hard is that for people to do?
It will take AirSnort all of 30 minutes to crack your 128Bit WEP encryption since it is so badly flawed that I'd rather go _without_ it.
Really, _don't_ trust WEP. Search Google or Ask Slashdot about cracking it, have a look at what You'll find.
The only reachable IP on my 802.11 net is the IPSEC gateway.
...but they're mostly graphic. I hold a "Windows Gems" folder with screenshots of the best ones.
One is a confirmation dialog box in which you have FIVE buttons: Yes, OK, Abort, No, OK.
One is Easy Cd creator saying that "The CD cannot be erased. The CD could be dirty of damaged. Clean the CD and retry. Usually, erasing the CD is an acceptable solution". Never figured out the last part of it.
Then I have 2 different flavours of dialog boxes titled "System Error" saying "Operation Completed Succesfully" and only an OK button.
I also have a scary "Cannot exit Microsoft Excel" (!!!) one, plus a whole subfolder of terrible Italian messages translated from the English original with some automatic software..... some real pearls in there ("Guidatore" instead of driver, "Galleggiante" instead of Floating Point)
Are you sure that you aren't just hitting a bottleneck in a USB2 device running connected to a PCI slot? (PCI is the bottleneck)
Not likely (unless the USB controller chip is real crap, which does happen).
USB2's bandwidth is 480 Megabits which equates to 60 Megabytes per second.
PCI, in its slowest incarnation (32bit, 33Mhz, the most common flavour) does 132 Megabytes per second, aka 1.056 Gigabits/sec.
So the culprit is hardly PCI (unless some other PCI card is hogging the bus).
As others already pointed out, you are confusing the NAS and SAN concepts (but is it your fault? look at stuff like EMC Celerra HighRoad and then you'll be confused:-) )
Anyway, Want to exploit 1394 (heck, we can finally call it Firewire!) to mount a disk? You just need a 1394 enclosure for your regular IDE disks. Example.
Want to exploit 1394 to access a network share via SMB/NFS? You can, with Ip-over-1394 (works on Apple, Linux, Win ME and XP. Not on 2000). You just load the correct modules and it shows up like a network interface.
Just my 0.02.
I am not associated with the linked shop, I just happen to be a happy customer of theirs. Their Fire-I webcam is really cool (640x480x30fps) and it's amazing how well it can focus on extremely near objects, it's almost a microscope. I put it in contact with the screen and was able to focus on single pixels.... now that's a nice way to really study ClearType:-)
Once added to the list, there is no way to appeal the blocking or to fight such policies
This is bullshit, and he knows it, but he has to exaggerate and distort the truth in order to highlight his fashionable Bounty idea.
I inadvertedly ran an open relay and quickly ended up on Ordb, and rightfully, I might add.
My mail server logs had this nice explanation given in the error message from other servers, complete with a helpful link explaining how to fix and get delisted (fix your server, resubmit its IP for checking, get automatically removed).
3 hours and a sendmail.cf later I was back with the good guys, and had this nice warm feeling:-)
Satelite is more like 500ms each direction for geosynchronous orbit.
Ehm, no, sorry.
It's around 280ms, and believe me, since i work in a satellite ISP.
Clarke's belt is at 36.000km of height, which, considering we're not exactly below the satellite (like at 19.2 East longitude, exactly on the equator, aiming straight up at an Astra bird), we must increase to some 40-42.000 km. Once for going up, once for going down = 80-84.000 km total. Now speed of light, last time I checked, was roughly 300.000km/s, which means that 84.000 km are covered in 0.280 seconds. Your mileage may vary by a tiny fraction depending on where you live on the crust planet surface and how far (latitude/longitude) the Bird you're aiming at is, from your location. Let's say between 240 and 320 ms
....and if you don't believe me, I have pings!!!:-)
I live on the other side of the pond, so no CDMA here, but GPRS instead.
I've been using a GPRS phone (4+1 - more or less 40Kbit to receive, 9.6 on transmit) to give connectivity to my brother, since the house he's in has no telephone lines, and GPRS, although being the most expensive thing you can imagine (around 7/megabyte) is often offered free for whole seasons (unlimited traffic for 30 days at some 10, renewable).
It's not incredibly reliable (the house is in a godforsaken area) but heck it works. MSN messenger and a few downloads go just fine if You take into account that it's costing you nothing. But DO get a download manager because you're guaranteed to be disconnected before you can get that 30MB download finished.
Still have to figure out why there is a 700-800ms latency (heck satellite is 250), maybe it's been artificially introduced to discourage voip:-)
Basically, my experience is: OK: Web surfing, Instant messaging, email
Sorry, I don't have a link. I saw it in a shop (in Rome, Italy) last year: a small 5-port (with 6th connector also, which is 5th port but crossed over) which would run off a 5v DC power supply or a little pass-thru PS/2 adaptor which would suck the power off the port.
I know PS/2 only gives very little power, but evidently it was enough.
I don't know by how much it would shorten a laptop's battery life, but heck, that was a nice, and Tiny! thing to carry along.
I am manager of a project with 5 staff. Before shoving it down the throat of my people, I wanted to use it myself and see if it's really usable/stable/reliable/compatible....
(I have quite a bit of unix/linux background, detonating kernels and X servers for some 10 years, not your average newbie)
It's Ugly and Slow. I'm still using because I don't want to shell $$$ to Micro$oft which is rich enough already, but it's unpleasant when it takes 14 seconds to start on a P3-850 w/ 256MB. I more often end up moving the document to a PC with Office, working there, then taking it back, using OO only as an emergency.
Only recently I discovered AbiWord and it was instant love: 3MB installer, small memory footprint, starts in a flash, and it's NICE!!!!
OO is soooo unsexy (and memory-hungry) that I avoid using it whenever possible. Its UI definitely needs some work, not even the scroller on my touchpad works in it (it does in AbiWord and in everything else).
If only there was some usable Excel replacement for the Win32 platform (Yes I'm running Win2K on all office PCs. No Linux, sorry, it's not really ready yet for the desktop.) a la gnumeric, I think OO would disappear rather quickly from my PC.
The scoundreles that inflicted so much pain cannot hurt us any more, but we must find it in our hearts to forgive them.
We will never forget 9/11/01, but holding a grudge against a people is counter productive if we are really trying for World Peace
Sure. World Peace. After the last one of them is erased.
