Currently 1000 users == 1000 streams. An intelligent switch looks at the content, says broadcast one stream to the 1000 users. Sounds simple. Not, though. Check articles on "Layer 4" switches.
congratulations, you just described multicast.
Multicast has been support in routers and OS's for years. No new propreitory systems needed.
I was a bit disappointed when redhat stopped installing gcc in the base install a while back and when they just recently started surpressing core dumps without a simple gui to turn it back on. A newbie + a core file + core analysis program ( eg. bug-buddy ) can be a wealth of info for a open source programmer, and a lot of the time is just about the only way to get pertinent information from some absolute newbies.
I bet if they polled their users there would be a overwelming majority of users that installed gcc or at least tried to after a base install. Maybe to install a random program from SRPM or something.
Why does this matter? Redhat linux is becoming less and less of an attractive testing platform. To get crash analysis information from newbie users, I have to walk them through
(i) installing gcc - because no unstripped binaries are made available.
(ii)build
(iii)enable global core dumps
It rarely ever works out with absolute newbies.:)
Redhat and a lot of OS projects are just mimicking microsoft's moves instead of focusing on our unique advantages. I believe the distro that corrects this, and does it well, will get a significant share of Redhat's market.
"Debunking the other H1B Myth: Under qualified IT jobseekers blame H1Bs for stealing their jobs."
The numbers can be played either way. If there really was a conspiracy for cheap labour, much more H1Bs would be working in IT. Fact is very few firms now hire H1Bs, and for many firms not hiring H1Bs is a matter of policy.
I'd like to analyze this issue objectively, and so any paper that rests so heavily on stats without supplying it's own raw data I'd question. For example, was it taken into consideration that H1Bs very often apply for jobs in lower pay brackets? Eg. call centers, tech support etc? This would lower H1B median salary without any foul play.
Here are some features that I would love to see a decent search engine supply. Altavista use to offer all of these but it's indexing is, well, you know how they've been lately.
(i) Case sensitive searches. - Great for searching for acronyms that are also real words.
(ii)stemming - this is my biggest grip. Say you remember a company who's name begins with "blue" but you can't remember the rest. With a search engine that supports stemming you can search for "blue* inc" or "blue* +whateverindustry". With my knowledge of information retrival limited to a single grad class, I'd say google can'ed stemming for search performance, but damn, it's a useful feature.
(iii)proper language filtering - googles language filtering is somewhat broken. I have english as my language and still get even oriental language pages in my search results. I don't know how AV did this, but it worked much better.
IMHO, other than that Google is a great search engine. "Google news" is a great resource.
sorenson seems to want to license their codec to other vendors. I think they tried to with macromedia, and apple sued them. Looks like an exclusive license.
The case apple vs. sorenson case is still in court.
AFAIK. There is. Check the herionewarrior.com website. I think there's even multiple implementations out there. Quicktime codecs are another story
What's needed is the sorenson codec, the most common quiktime codec. Something the nice people at apple have been blocking for years now. Yeah, go apple:(
That means, if an editor wants to use the quicktime format on linux for editing he/she can, their just can't use the sorenson codec. Yes this makes it useless for many people, but not all.
I've had splint.org in my sig for a while now. I think it's one of those projects that needs more attention. This project used to be called lclint but got renamed to splint.
There are lots of papers out there on static checkers. One good intro paper is at
http://www.research.ibm.com/people/h/hind/paste01. ps. This would give you a nice intro on pointer analysis, a sub topic in static analysis..
So they can get the nimble development cycle of such projects as Mozilla and Gnome?
You are assuming that is projects have slow development cycles because they are opensource.
What about the Linux kernel? Last time I checked it was open source, and has probably the fastest devel cycle of any OS I know of.
A slow release cycle is not necessarily a bad thing. Solaris has a slow release cycle IMHO, and I am very pleased with the result. How could you even say that Open office has been slow, btw.? Try comparing its release cycle to other office suites out there. For the major changes introduced in 6.0, is it still slow?
BTW, there are open source PDA distro's out there. Take OPIE http://opie.handhelds.org/ for example. Way faster release cycle than the PalmOS, cross platform ( supports Sharp Zaurus and Compaq iPaq ), tons of apps available, because it's Linux. If Opie found it's way to more PDAs as the default OS instead of an after-market option, then I'm sure it would be a force in the marketplace.
You can't take an abstract and limited system like discrete math and apply it directly in the real world, to anything but abstract and limited systems.
Yes you can.
The crutch of the matter is to abstract the real world problem to the point where we have all possible states of all variables in the equation.
This is not an easy task for anything but the most trivial problems, but to say that it is not possible to prove something does not exist using logic is wrong, and that's what I wanted to point out to the original poster.
Yes, we are a long way of from proving/disproving God exist with a descrete math equation, I know:)
However in cases like that one generally resorts to Occam's razor,...
I don't mean to flame, but Occam's razor is largely a lazy cop-out.
Either...
i - the results are inconclusive and stop the investigation, or
ii - All possibilities are explored as true and examined.
Either way, say "I'm just going to choose one" is no longer scientific, not unless the principles of statistics are honored, eg. correct sample sizes , etc.
I don't know about IE, but netscape/mozilla supports roaming profiles using LDAP. That way, all your profile info gets saved in the LDAP server and you just configure your browser to pull the information from that server.
LDAP is also often used for other small pieces of information like certificates, etc.
I don't think that the whole email thing is a particularly good solution to the original question, but why should he pay for microsoft exchange when he could do this with any IMAP email server?
Shared folders, server-side mail storage, SSL/TLS security are all part of the IMAP/IMAPS protocol that many ( most? ) free email servers support very well?
So why should he pay the $10-$40* per user license for microsoft exchange? *( lost track of the price )
Unless you want to share your data with lots of 'friends' you just haven't met yet.
NFS is used very often to mount home directories. But what is stopping someone from unplugging the workstation, plugging in a linux laptop with the IP of the legitimate workstation and mount the share, "su - user", and voila, you now have all the user's files.
That's just the simplest way. The problem is that most NFS implementations don't have *any* authentication except for IP authentication. So so other DNS attacks would work as well.
I am surpised that the most widely used network file system implementation for linux and most posix OSes has no real authentication. There *has* been authentication built in the protocol since version 3, but last time I checked, it was not supported on the linux. I was told by one guy working on the project that the problem was that there's no crypto in the kernel.
I used secure NFS on Solaris 8 for a while but I constantly lost the mounts. That but be fixed now, I don't know.
Use AFS, CVS, rsync, intermezzo, or something. But I would stay away from NFS.
where can I download these free/cheap updates. Please do tell. Cause right now I have a lab of SGI that won't be upgraded with the lastest overlays because management will no longer pay for sgi support.
I doubt sharing overlays ( sgi os updates ) is legal. sgi charges a lot of money for those.
but I could be wrong, so *please* correct me if I am.
I'm a network admin as well. I'm working on implementing a wireless network as well at my day job ( small campus ). We just completed testing our initial vendors, and basically enterasys got it's butt kicked by cisco and agere ( formally lucent wifi division ) orinoco.
Cisco came out to be the most powerful. No fair though since they transmit at 100w while the others come in about 30. But for value orinoco rose to the top. $75 nics, dual radio models for $600. checkout http://warehouse.com/ for some discent prices.
both agere and enterasys have removeable radios on their APs, in fact the radios are just wifi pcmcia cards. The enterasys pc cards are OEMed orinocos.
My recommendation is orinoco. But your findings might be different, so definately check it out for yourself

It's not silly. I think you, like many, just haven't grasp the concept yet.
You, my friend, need to take a course in discrete math.
'!E', ie, "there is none that fits the following claim" is a very elementary concept in logic proofs.
Try LDAP for roaming profiles. At least netscape/mozilla allows you to store your profile on a specified LDAP server. I'm not sure about IE.
Try a search on google for LDAP roaming profiles for more info, or try the OpenLDAP mailing list.

i) cheaper than 802.11b to produce. there was a guestimate that the chip would cost $5 in bulk. Far cry from 11b I'm sure.
