Movies do not end until the credits have finished and the projector has been switched off. I hate it when everybody just starts getting up when "Directed by" flashes into the screen and getting their jackets and starting to call their friends on their cellphones etc.
When credits roll, you have time to digest and go through the movie experience, relax, and reflect, while still maintaining the 'mood' that the movie has created. (Especially if you happen to be on a date and watching a 'chick-flick' - you can keep the nice, romantic feeling going instead of rushing into the jam-packed exits and stepping on other people's toes). Granted, this may not apply to all brainless actionflicks, but I digress..
I'm glad that more recently, more and more movies are putting stuff (some little joke or something) after the credits (Pirates of the Caribbean:Undead monkey comes at you, Phantom Menace: Darth Vader's breath, etc. See IMDB:s "crazy credits" for more details.). Makes more folks stay PUT until the movie is really finished. Of course, people like Jackie Chan have always inserted bloopers to the credits sequence..keeps people in their seats.
So, if you got up at the end of RoTK for three times...well, too bad! If you really were in such a hurry why didn't you leave on the first time? You could at least wait through the initial credits sequence (Director, cast etc) if you are not interested in names of key grips and listening to the soundtrack in the theatre is not good enough for you.
...despite the fact that the standard/extended edition cycles were announced like year before Fellowship of the Ring's (first film!) DVD release.
And even if you missed that, by now you should know how it will go..pattern recognition, anyone?
Yes, there will be a boxed set with all the extended editions bundled into one nice compilation, but nothing beyond that. And if the Hobbit ever comes, they might also release a new box set with the Hobbit included. And they will release Bluray/HD-DVD versions when the formats become available.
However, the actual *content* will not change. There's the extended cut and the theatrical cut. No need to bash Peter Jackson about squeezing money out of gazillion different editions..So there will not be a "hook" to upgrade to the later box set releases (HDTV resolution on the next format might be enough, of course...but then you probably are not going to feel ripped off).
There is not yet an equivalent mechanism for "stateful autoconfiguration," which is more what DHCP is, where you can automatically assign an arbitrary address to a client. You can of course statically configure an interface to have a specific address, but there is no automated mechanism to always assign a particular autoconfigured client a particular address you designate. There are proposed standards for an IPv6 version of DHCP, however, and I expect eventually such a beast will eventually come around.
And yeah, I tried this out like one year ago, works OK. Besides the sourceforge project, HP-UX also supports DHCPv6 and comes with a server.
DHCPv6 is not necessarily used for address allocation (altough it can be used for that, too) since the stateless config exists, but you'll get info on name servers, ntp servers etc that way. So no leases necessary in here, either.
According to the instructions at UTD (see here, thanks to the other poster) they have 802.1X in use. This would have helped, because you can have mutual authentication. Of course, everyone needs to install Univ's Cert beforehand, but anyway, fake AP's are pretty hard to do in mutually authenticated environment.
Okay, I can see one of the reasons they wanted to do this was, according to the article, not interference per se, but this:
The connectivity problem stems from the fact that, if not told to do otherwise, many wireless cards will automatically connect to the strongest signal available. In Waterview's case, a network card might jump onto a neighbor's stronger access point instead of the possibly weaker UTD wireless network. The network swap can cause a "denial of service" conflict and a failure to connect to the Internet, Jackson said.
IR officials said they hoped shutting down personal access points would stop cards from arbitrarily swapping their signal source.
Now, just WTF are they thinking? Of course if I don't configure my WiFi card to a specific SSID, it'll use whatever network happens to be close by. Couldn't they just have set up an instruction sheet that said "if you want to use our network, set your SSID to campusnet" or whatever? In Windows XP this is trivial, with older ones you may need to go to network driver settings and punch it in there (or use software included with the card). With Linux you just say iwconfig wlan0 (or whatever your device is) ssid blahblah.
I'll grant that they do have a problem with gazillion wireless networks combined with default settings for Wifi cards, but they clearly went the wrong way of dealing with it. Considering that even warchalk markings include SSID names, I don't think it would have been too much trouble to give instructions on how to set up your card.
Why packet writing to CDRW's STILL isn't nativly supported by most major OS's is beyond me. CDRW media is dirt cheap, and 400 times bigger than a floppy but making the average user go through extra clicks and disconnecting the ideas of "dropping onto a disk" and "writing TO the disk" is just the stupidest thing.
This is something I don't understand either. I bought like 4 or 5 years ago my first CD-RW drive, Philips CD3660 (2x/2x/6x) and THAT came with Ahead InCD, allowing for packet writing. Just format a disk and you are set. Problem: you needed the Ahead InCD at the other computers you use, too...
One of the nice things was that it actually worked for CD-R:s, too. It just marked the previously written portions as stale and to be ignored.
However, back then, packet writing was like 1/4 slower than just burning standard ISO9660 disk. With 2x speed, this WAS an issue...and now, with 50x speed burners, the ISO9660 is almost as convenient as packet writing. Might start to use it once DVD+R DL media prices go down, though.
"In fact, trolls traditionally count like this: one, two, three...many, and people assume this means they can have no grasp of higher numbers. They don't realize that many can be a number. As in: one, two, three, many, many-one, many-two, many-three, many many, many-many-one, many-many-two, many-many-three, many many many, many-many-many-one, many-many-many-two, many-many-many-three, LOTS.
This topic has come up on Gentoo forums so many times that I'm not going to repeat it here, but using ACCEPT_KEYWORDS or emerging an ebuild directly is BAD. Read man portage and see what the files in/etc/portage are for.
Probably not. It was meant as a general statement as in passive "you" meaning everybody in general, not myself. It's just something that I've noticed, especially in cases where you can quite easily measure someone's skills. One clear example that I see quite often is what people put in their CV's in the "language skills" (This is a Finnish POV, so everybody usually at least learns English).
It's just that folks that have studied in university quite often just put "good" or "average" in some language even though they, for the most part, are much better than the folks that have only gone through high school (and who put "excellent" in their resumes). If you have taken and passed 15 CU's of language courses you're bound to know more..
(BTW, kiddies, if you say you're a "senior network engineer" and you say that you know OSPF and I ask you if OSPF uses multicast or unicast and when does it use it/them then you had better be able to answer the question...)
I know most of these things, altough I'm not sure right now (2 am, and I've been on vacation for the last three weeks) what (if any) are the considerations on point-to-point or p-mp (Non-broadcast) links or other more special cases. However, I wouldn't in my right mind call myself a "senior network engineer".
Oh well, I guess it comes with the fact that the more educated you are, the more modest you get.
However, I don't really thing that the details are too important. I know OSPF is a link-state protocol where every node in a network knows states of all the other links in an area and calculates Shortest Path using Dijkstra's algorith. IS-IS is similar. RIP is not. If I need to suddenly remember what exact numbering scheme was there for the link-types 1-7 I can always look up a reference (L5 are external routes, L7 are NSSA routes, cannot really remember the rest nor do I care? Show ip route ospf tells me all I need to know on whether it is intra-area or inter-area).
Just pointing out that you really cannot evaluate someone's knowledge by posing questions about minor details unless you are perhaps hiring somebody with a CCIE (and then you can probably start with more obscure ones about DECNet).
(Anecdotal note: I was hired as a trainee by my current employer probably because I confessed in the interview setting up LANs with IPX/SPX back in -94 so that all us kids could play Doom. I guess they went for the enthusiasm and my genuine interest. Granted, later I was able to shine when the boss was around and I was just discovering an obscure bug in two different vendors' BGP stacks timer synchronization - Don't know if that had any effect by I got hired permanently).
A certain finnish computing magazine has a policy that there will be no capitalization of ANY term. That's right, all acronyms (GPRS, VoIP, LAN, ATM) will be in lower case (gprs, voip, lan). If it's a product that has some weird-ass capitalization (iTunes, iMac) they just do it all-lowercase. (How would you use iTunes in beginning of a sentence, anyway? ITunes?). However, names are not in lower case, ever. IBM is still IBM. Actually, if you check out the page now, you can see in the left pane a blurb about Gmail (in uppercase) and video at VGA resolution (in lower case).
I gather that they originally came to this decision because lots of writers started to ask the questions that how are they going to write all those L33TAcRoNyMs that everything that is nice about language, and they made a blanket decision. (Again, how do you use iTunes in beginning of a sentence...).
This sometimes pisses the more technical engineering crowd off because they prefer the original form, but they have stuck to their line. (Oh, and I'm not a subscriber:))
However, even they have not touched names. Internet, The. There are also intranets, extranets and internets.
Each time there was to much battle in one area the virtual creatures where fleeing to security and the result was a bunch of cowards avoiding fight... They corrected the problem by making them dumber.:)
No..The first versions had a bunch of 'agents' running away. The reason was not that they chose the most intelligent action (ie. running away), but because they could not find the opponent. They had to revamp the agents' senses so that those on the edges of battle could actually find their way to where the action is.
If I trust what I learned with the 12cm optical disks I currently use (CDRs), my entire life would last about 2 years before getting unreadable.
Frankly, if you've CDR's that have gone unreadable in 2 years then you must have somehow mishandled them or gotten a bad batch. One of my friends lost a bunch of photos because he had accidentally marked them with a marker that contained solvent.
However, correctly handled, the CD-R:s should last quite long. I've a few that are over 10 years old (burned back in 1993 with a single-speed CD-R-drive or something like that). And they still work just fine. I've never had a CD-R fail on me except during the burning phase.
Oh, incidentally, one of those CD's from -93 contains all the stuff I had with my 5 1/4" floppies. Upgrade your data to a better media if necessary. However, I would thing that the CD-sized optical disc remains readable for quite a long time. The form-factor is just so...convenient that future standards will probably use it, so your HD-DVD and Bluray drives can read CD:s just fine.
On occasion, someone will write up a nice summary of highlights. Anyone seen such a thing for 2.6.8?
Kerneltrap usually posts one shortly after release. Not yet posted for 2.6.8, though, but check periodically, I would think that they will update later today.
When it comes down to radiation and absorption on the surface of an object, all that really matters is the blackness of the surface.
A very good example of an application is in MESSENGER. The side facing the sun is white, so it will absorb less heat. The side facing away from the sun is painted black, so that the probe will get rid of the heat even faster.
very stupid question from a non-engineer : is it not possible to have non-directed optical signals ? Some sort of 'ambiet laser'
Um, yes. Just take a look at your closest lightbulb. There's your omnidirectional light source right there. One might actually consider variable stars as messages from outer space...
In the interests of mentioning something real that actually exists, take a look at 802.11 over IR
Lasers are used for point-to-point links because there is usually an intended recipient. All of the energy goes to that single, intended direction. However, there shouldn't be anything to stop creating ambient monocromatic light source..
Seriously, the Metric/Imperial thing happened like 1999. Since then we have had Galileo end it's mission successfully, Mars Odyssey (2001), The exploration rovers, Cassini has so far performed flawlessy, and the hard part is over (Orbit insertion), NEAR, an orbiter, landed softly on an asteroid on it's solar panels, Deep Space 1 did the comet Borrelly encounter, Stardust has successfully collected the comet material (return in 2006)..and probably others that I don't remember offhand.
I mean, after so many successes, and some folks *still* don't let go. Now, if one of the probes were lost *again* due to a measurement system error then we could get a laugh out of it, but so far...they have not done that. Granted, in 1999 the *other* Mars probe, Polar lander was lost too, and so was Deep Space 2. But still...that's five years ago, and NASA has had loads of successes since then.
This is kinda starting to resemble *BSD is dying trolls..
Does anybody know whether these new changes/features (in IE and elsewhere) will ever make it into Windows 2000 (which at the moment seems to be the most preferred Windows at least in corporate environments). Win2k SP4 pretty much covered everything in XP SP1, but not much has been mentioned since then.
I have to agree. From the Slashdot blurb, I thought that this might be an "alternative guide" for Cisco stuff if you are already familiar with the technology (and maybe have experience configuring other routers or maybe just Linux/Unix boxes and are just getting your first IOS box in front of you). This is just...bland.
Those exercises in chapter 1 are hilarious. "What.EXE files are found in windows\system folder?". C'mon, I thought this was about networking if not Cisco-specific stuff.
I didn't bother to read it all the way through, but it's talking about such groundbreaking tools as "ping" and "traceroute" (still in Windows) somewhere around page 120. The index is at the end, and it seems that it does cover RIP at least.
I guess it wouldn't really bother me all that much if the good professor would clearly mention that this is course material for Computer Networking 101, and has NOTHING to do with anything that is really Cisco-specific. More like Windows-specific.
Well, I guess I was expecting a guide on how to set up VRF's and configure MPLS traffic engineering based on the remarks at Cisco. For a "network basics"-stuff it might actually be a good one, altough I would assume that anybody that is going to set up a network knows at least basics in Windows/Unix and would only list that as a prequisite. Covering Windows command line fundamentals in what is supposed to be a networking guide is just silly.
My computer is setup to use both IPv4 and IPv6, that makes IPv10! One bigger than IPv9! Eat that, China!
While YOU are making this as a joke, I have a personal anecdote that really made my skin crawl. My (telco) company execs routinely used a term "11.5G", referring to "11.5 generation network", meaning 2G (GSM) + 2,5G (GPRS) + 3G (UMTS/WCDMA) + 4G (WiFi) concurrently.
Luckily, that buzzword was later changed to something about seamless mobility or something, basically just meaning that a terminal can roam between different radio network technologies. But for crying out loud, they really thought that this BIG number shows us being years ahead or something..
This is the old April fools joke, yes, but I have to ask if this is some sort of new thing. Doing a Google search for IPv9 returns bunch of IETF mailing list postings talking about that joke, and then loads of chinese pages. Is the article a new and improved version of the joke or something that really exists?
Wow, the Finnish bank solution is way overkill. I'd rather have to deal with identity theft every 5 years than to keep a list of one time use passwords.
The list is a credit-card shaped piece of plastic that has a bunch of numbers on both sides. Goes easily in wallet. Doesn't matter if it gets stolen because you still need the username/password pair and you can get a new list by calling your bank.
And like I said, you can still use the smartcard version (so you'll skip the typing of one-time-password entirely).
...I don't know about banks in the US, but at least my (Finnish) bank gives me a username, password and (most important of all) a list of one-time passwords. When I log in, the only things I can see before it requests a one-time password is the balance on account, EURIBOR interest rates and the few stocks I've chosen to observe (ie, a master summary page). If I try to access anything, such as transaction records (not to mention transfers), I have to type in the one-time password. They mail me a new sheet when I'm starting to run out of one-timers.
If I don't want to use one-time passwords, I can choose to use smartcard reader and a PIN number (which remains constant). I'm not sure if that would be vulnerable. Anyway, this follows the "something you have, something you know"-security model, I know the username/password and have either the smartcard or the one-time list.

From the Slashdot blurb, I thought that this might be an "alternative guide" for Cisco stuff if you are already familiar with the technology (and maybe have experience configuring other routers or maybe just Linux/Unix boxes and are just getting your first IOS box in front of you). This is just...bland.
.EXE files are found in windows\system folder?". C'mon, I thought this was about networking if not Cisco-specific stuff.
Those exercises in chapter 1 are hilarious. "What
I didn't bother to read it all the way through, but it's talking about such groundbreaking tools as "ping" and "traceroute" (still in Windows) somewhere around page 120. The index is at the end, and it seems that it does cover RIP at least.
I guess it wouldn't really bother me all that much if the good professor would clearly mention that this is course material for Computer Networking 101, and has NOTHING to do with anything that is really Cisco-specific. More like Windows-specific.
Well, I guess I was expecting a guide on how to set up VRF's and configure MPLS traffic engineering based on the remarks at Cisco. For a "network basics"-stuff it might actually be a good one, altough I would assume that anybody that is going to set up a network knows at least basics in Windows/Unix and would only list that as a prequisite. Covering Windows command line fundamentals in what is supposed to be a networking guide is just silly.
Back in my first year or two of programming full-time, I deleted some LIVE data belonging to a customer, because I forgot the "where" clause.
Umm, couldn't you just have said "rollback;" after your mistake? Or did you have auto-commit on?-)
My computer is setup to use both IPv4 and IPv6, that makes IPv10! One bigger than IPv9! Eat that, China!
While YOU are making this as a joke, I have a personal anecdote that really made my skin crawl. My (telco) company execs routinely used a term "11.5G", referring to "11.5 generation network", meaning 2G (GSM) + 2,5G (GPRS) + 3G (UMTS/WCDMA) + 4G (WiFi) concurrently.
Luckily, that buzzword was later changed to something about seamless mobility or something, basically just meaning that a terminal can roam between different radio network technologies. But for crying out loud, they really thought that this BIG number shows us being years ahead or something..
This is the old April fools joke, yes, but I have to ask if this is some sort of new thing. Doing a Google search for IPv9 returns bunch of IETF mailing list postings talking about that joke, and then loads of chinese pages. Is the article a new and improved version of the joke or something that really exists?
Wow, the Finnish bank solution is way overkill. I'd rather have to deal with identity theft every 5 years than to keep a list of one time use passwords.
The list is a credit-card shaped piece of plastic that has a bunch of numbers on both sides. Goes easily in wallet. Doesn't matter if it gets stolen because you still need the username/password pair and you can get a new list by calling your bank.
And like I said, you can still use the smartcard version (so you'll skip the typing of one-time-password entirely).
...I don't know about banks in the US, but at least my (Finnish) bank gives me a username, password and (most important of all) a list of one-time passwords. When I log in, the only things I can see before it requests a one-time password is the balance on account, EURIBOR interest rates and the few stocks I've chosen to observe (ie, a master summary page). If I try to access anything, such as transaction records (not to mention transfers), I have to type in the one-time password. They mail me a new sheet when I'm starting to run out of one-timers.
If I don't want to use one-time passwords, I can choose to use smartcard reader and a PIN number (which remains constant). I'm not sure if that would be vulnerable. Anyway, this follows the "something you have, something you know"-security model, I know the username/password and have either the smartcard or the one-time list.
Do the US banks only use username/password pair?
