watch for any packet coming in, or try and elicit a response by trying some common network requests (I'm thinking some kind of multicast "ping" but the correct term escapes me)
Anyway when you get a response you can try a reverse-ARP -- the machine *should* spit back its known IP. Of course you won't have any idea what the netmask or gateway is, but screwing around you may be able to determine this info.
It's an awful lot of non-standard work just to get this kind of bad bad system to work. You have to basically snat packets from the user, dnat packets to him and really really screw with the packets. It's not straightforward and it won't likely work well. Make them use DHCP or nothing. Or provide a network-terminal in the room for them to use. Honestly it's not a good situation any way you look at it if you won't accept them reconfiguring.
Its interesting you give a link for that phrase, as it doesn't mean what you think it does.
Heh, yeah I personally tend to call cases where you just take an arguement to the extreme reduction to absurdity, whereas the formal definition also requires it to be negated. Oh well.
But by those criteria KDE and Gnome (and Apple Macs, and MS Windows &c&c) are functionally identical. No less different than the controls in a Lexus from a Chevy Nova.
I don't expect to find both Lexus and Nova controls in the same car. That was the point I was trying to make.
Thanks for the link. It's missing the goal though. We already have a killer email app. We already have a pretty damned good newsreader. And so on for the PIM. Why keep rewriting these bits? I have not looked into this yet but there should be a way to write a "shell" around the DCOP bits of these three programs which brings them all into one unit and, if I only need to fire off an email, can still pull up KMail and get at my messages without loading up everything else.
Reductio ad absurdum. I expect that the two dials on my microwave operate the same way. I expect that every car I drive have controls that operate closely to each other. I expect that the remote I use on the couch be able to drive my VCR, DVD, Satellite and TV.
Evolution runs in KDE just fine - do you have the gnome libs intalled?
You're missing the point -- I want all my apps to have the same look and feel. Using two (three) different widget toolkits is not conducive to this end.
KMail/KNode/KOrganizer gets me close but I admit, Evolution has the integration aspect nailed down pretty damned good.
Apparently they did. But the tape backup is broken so they can't retrieve the data.
Which is why I have access to another tape drive offsite. Now mind you I am only using DDS3/4 so the cost of another drive isn't staggering, but still... why have backups at all if you don't have a method to read off the backups if the building explodes?
I agree. What the company I work for does is urge you to take courses related to your job or where you want to be in the company and, depending on your grade at the outcome, reimburse you based on that. IIRC the scale is something like A-B - 100%, C - 70%, D - 50%.
You get a speed penalty by doing ECC, because the ECC controller have to calculate a check sum for every write, and check the check sum for every read. Even worse, the ECC check sum is block based, so the ECC controller have to read the whole block to calculate the check sum even if the CPU only reads a single byte.
It's my understanding that ECC works on the smallest data width available, which is 64 bits on SDRAM anyway. When your P4/2.1G grabs a single byte and there's a cache miss, it fetches the entire row (8 bytes) from RAM anyway. Block-based, yes, but no bigger than normal.
As for speed performance, give me a break. The RAM is zillions of dollars more expensive not only because of the extra memory cells but also because (IIRC) the code generation is done on-chip. The checking is done by the chipset, IIRC, and that is all done in hardware and I'm willing to bet in the same amount of time that you can do a normal read in anyway. I haven't been able to google up performance benchmarks on it though.
Why the original poster was getting parity errors was not only because he had ECC checking turned off in BIOS, but also because ECC cannot correct all bit errors. Most ECC checks can correct single-bit errors, but double-bit and higher errors cannot be corrected since enough correction code is not stored. It's just like hard drives, CDROMs and DVDs: they can spot and correct incredible amounts of relatively small errors without telling anybody about it, but if the error is just too large it has to pass back a "bad data" message.
In fact some of the only reasons that we have such huge amounts of storage in formats that we can actually paw up with our hands is because there is such a vast amount of error correction coding on the media.
Steltor (warning, some flash) creates Corporate Time, a Windows and Linux client and server package which is supposed to give Outlook and Exchange Server a run for their money. They have similar Outlook service DLLs if you want to run Outlook, too.
I evaluated these guys very briefly last year and it looked VERY promising. They're priced similarly to Exchange but you can use any LDAP and any IMAP/SMTP server, although shared folders won't work unless your IMAP server supports them. If you want an all in one solution, use their server software (which is, IIRC, OpenLDAP and Cyrus, not sure of the SMTP server or shared calendar server though). The tech support was actually clueful and helpful. I will be taking another look at them shortly, as my initial evaluation got cut short due to other projects becoming higher priority.
I tired Bynari back in '99 -- I didn't like them at all. The install obliterated my existing SMTP/IMAP/LDAP settings without warning and tech support (at the time) was a high school kid who was never there (presumably at school). I may give them another shot too because they really were the first at the plate when it comes to this, but Corporate Time also gets rid of Outlook which is a big pain in the ass, and they seem VERY happy to just sell you the client side stuff and let you use your existing MTA/LDAP setup, which is very important to me. qmail, vpopmail and Courier-IMAP have never failed me, and I'd rather know my OpenLDAP setup inside and out than rely on someone else's configuration.
Can you imagine trying to get a 35-meter dish antenna even so far as low-earth orbit, let alone on a solar-escape trajectory? Get real.
I see no such problem. Perhaps it is you who should take a little time to think before posting; The concept of a sectored parabolic dish that expands when it deploys is not a new concept. If you do that now you're down to an 18m long component. If you're willing to send it up and have a crew assemble it instead of have it self-deploy en route to its destination you can get that number down MUCH smaller.
MS is trying once again to takeover the minds of the children.
It's working here in a small rural high school in Canada. They put in modern comptuer labs (about 30 win2k, P3/500, etc. in each class) -- OSS can't match them there and it's kind of sad. But it's happenning here in rural Ontario.

I'd mod you as flamebait, but it looks like someone else already did. Quit spewing FUD.
I've set up a Jabber server over 6 months ago and I'm using a client called Psi. I regularly connect to the MSN and ICQ networks through my server. I have not experienced one problem, much less the disaster you predict.
I prefer Jabber to the mess of carrying a cellphone, pager, checking email and the office phone. Yes I have them all but I only carry the cel/pager when necessary. I tell people to use Jabber or email if the need to get in touch with me, since telco charges are expensive and I'm not likely to be at the office anyway. My email client isn't always open but my IM is. Jabber is excellent for tying things together.
In a similar vein, if someone were to suggest to me firing anyone who suggested Jabber I'd end up firing them for being so small-minded. I've far less use for a person who won't consider new technologies than someone who is constantly on the lookout for the next best thing. Then again I'm the network admin for this company, so what do I know?
I agree wholeheartedly. When I went from Windows (ICQ99b) to Linux, I grabbed LICQ. Then when v5 ICQ protocol was being refused by the servers I went to Jabber and tried locating a client I could use that didn't pop up windows and didn't just have huge chat windows. In short, I wanted something light and fast and unobtrusive, like LICQ or the OLD Mirabilis client for Win32. I settled on Psi.
Psi is small, fast, cross-platform, simple and clean. I LOVE this client. I would strongly urge everyone who is using this client to send Justin a few dollars through his PayPal account to keep him actively developing his client. He responds to bug reports, accepts patches and tries to include feature requests. Open Source done right, I tell you.
I got really excited about Jabber for the longest time. I'm sort of disappointed in it now, since it seems like they're still having problems connecting to AIM and ICQ.
My jabber server has ICQv7 and AIM transports, and also MSN and Yahoo! transports. ICQv7 was a real pain in the ass to set up but is working perfectly. I've never had trouble getting on to the networks and even the "offline messages" that ICQ has had for years works fine now.
So I dunno, go use your own server or use an open server line charente.de for your ICQv7 needs. I really don't know what your trouble with AIM is though. I always thought of AIM as the retarded cousin of ICQ so I never use the transport anymore. (I was using it to get on to the ICQ network when I couldn't get ICQv7 compiled.)
but somehow the fact that somebody's already put together something like this, even just as a proof-of-concept, really makes me less confident about Linux, not more.
So let me get this straight... Because the system is more-or-less fully documented and has straightforward and clean APIs that allow you to poke and prod at it in a well-defined manner you are less confident about the OS? I'm sure glad you don't design cars or houses or medical equipment, that's for damn sure.
Once the technique is perfected, we'll have a supermarket of acceptable clone sources. Which person do you wish to clone? The smart one or the dumb one? The beautiful one or the plain one? The white one or the black one?
What's wrong with raising the bar of civilization? If done correctly, nothing. I'm not talking about Gattaca references here, I'm serious. Would you not want the best for your children? Wouldn't everybody? If you could screen your zygote and elimiate or drastically reduce the heart disease that runs rampant in your family, or the higher risk of cancer, or the anything, wouldn't you do it? If there weren't any drawbacks to giving your child beter memory or reflexes or learning ability, wouldn't you do it? If that choice were available for my children, I sure would have.
Yes, it can be abused. And yes, it can cater to the wealthy. These things have to be worked around so that we don't create a Brave New World or Gattaca society but the idea about making the human race as a whole healthier is not something to scoff at.
So two people with the same DNA will obvious not be reproducing in the usual way.
Correct. However imagine getting a clone to puberty and then taking the ova or sperm from both the original and the clone and creating a baby that way. No links handy but I believe that it is possible for two women to concieve through manipulation of the ova) -- would this 2nd-gen clone now be a healthy (in terms of good genes) human? Remember that the telomeres would be the normal length now since you're using the sex cells to procreate instead of normal, mature cells.
