The article says 'In applications such as telnet and remote desktop, a packet is sent every time a user presses a key' - is this the case with ssh too?
Far be it from me to question the article, but I had been under the impression that Nagle's Algorithm had been designed to concatenate small buffers—such as telnet—to prevent them from necessarily sending a packet with each keypress.
I am not a TCP stack guru (IANATCPSG?!), but it seems like, though this algorithm was designed to reduce congestion, it would upset a timing attack by having to wait for the ACK of the last packet—at least on high latency links.
SSH, at least as of 2002, according to this e-mail, turns on TCP_NODELAY, which disables the algorithm to reduce latency of keypresses in a connection when it believes an interactive session has been started. Thus, SSH does indeed send a packet with each keypress.
A small business owner friend of mine warned me about this when I had a dispute I hoped to negotiate. He said that the BBB doesn't really do anything but compile statistics on businesses, and that their only real benefit is to allow one to gauge the honesty of a business before dealing with them.
If you want to have some teeth behind you, he suggested, contact the state attorney general's office and file a complaint.
Community Living Standards is something they should be caring more about. Not community censorship standards.
I suppose, in correcting your error, I didn't really reply to your main point. I agree, the State really should be putting its energy towards bringing in more jobs, reducing pointless spending, and making sure Michiganders are healthy and happy, not merely pushing out legislation that vaguely defines objectionable content in an attempt to censor "bad" video games.
I can't believe that other forms of media are being so harshly judged. Up to $40,000 and 93 days in jail? That's pretty rough.
have you BEEN TO MICHIGAN LATELY?
Yeah, pretty much every day for, oh, the past 24 years, barring a few vacations and the like.:-)
I think they have bigger problems such as COMMUNITY LIVING standards in one of the poorest american states.
I read this and was pretty sure you were wrong, so I did a little investigation.
Michigan is above the national average for median household income by state. It might be just above the national average, however, it still beat out 29 states and the District of Columbia.
I don't think being above the national average by any means qualifies calling Michigan one of the "poorest American states."
we have had POTS outages for up to 4 consecutive days, although DSL still works.
Yeah, I also saw that happen, here in Michigan. A friend of mine ordered DSL, lost phone service, and spent several days trying to get it back up.
Strange random coincidence, though: Since my friend had a Nextel, and the service tech. was going to call him on that, we decided that we could go out running while the land line was being repaired. So, there we are, out on a service road back by his house running, and we see an SBC van. As we were about to finish running, we get a call from the tech. We start walking back, and pass not too far from the van, and see the technician talking to someone. We thought about waving, but further thought he might be freaked out, thinking us to be irate customers hanging out on a hidden service road, stalking him.
The question really should be are you getting what you pay for? I have friends who are getting inexpensive introductory rates with SBC, and who kept having outages for the longest time.
I just switched to SBC/Yahoo (for about $30/month) and I haven't had issues, myself. Knock on w NO CARRIER
Yes, there are several prominent cases of a school releasing Open Source code... but usually not for ideas that were new at the time, only for reimplementations of existing concepts.
Um, how about University of California, Berkeley? Of which, BSD introduced such features to UNIX as:
demand paged virtual memory
job control
curses
long filenames
select(2), socket(2), vfork(2)
union filesystem, loopback filesystem, FFS, symbolic links on UFS...
So I guess you could say that at least one very prominent academic open-source project released code for concepts that were new at the time.
black marks are LEFT there intentionally to SHOW that something was blacked out. If they wanted to "hide" the information, they would excise it.
If that were the point, why wouldn't they just strike through the text with a simple line (e.g. the <strike> tag in html) instead of blacking it out entirely?

The security advisory says that branches RELENG_4 (up to 11 November 2002), RELENG_4_7, and RELENG_4_6 (both till 6 January 2003) contain the bug. I'd post the appropriate parts from the advisory, but the lameness filter thinks that I'm posting "junk" characters...sigh...
the Mac OS X versions of Photoshop and Word come to mind.
Would this compatibility layer actually be able to run these once finished, even with the Mac libraries? Maybe I'm just forseeing problems where none will exist, but don't some carbon apps use CFM instead of Mach-O (can a Carbon app even use Mach-O?) Would LaunchCFMApp take care of this, given a copy of OS X's libraries?
Further, what about resource forks? UFS sure as hell doesn't support those, without some kludge (compare, for example, the way OS X stores resource forks in dot-underscore files on NFS, etc.)
I guess that this might be a nice way to run Cocoa apps, at least. I just wonder about reverse engineering all the minor hacks that Apple had to make for running Carbon apps.
Well, yes, especially for my dumb-assed regular expressions error. This is slashdot, I expected to get flamed for that. No one cares about flagrant assults on the English language, I guess...
I hatve to agree with this user that this will help the open-source movement. I was a Mac user for many years, and I dabbled a little with Linux, but after I got my hands on OS X DP 4, I really started to appreciate Unix-based OSes. I got myself an old 486 cheaply and put FreeBSD on it and learned even more.
Perhaps Linux might lose some popularity, but, overall, I think I forsee this as a great place for the unixes to grow. I mean, I've known a lot of Mac users who have been both Mac and unix users, and, one would hope, that this would open even more Mac folks up to playing around with unix. Not so much to be seen as competition, but perhaps as room for growth.

Rather curious, myself, what these crashes are to which you elude. I happily have been using the Beta release, and haven't taken down the OS once, and, boy, have I been trying.;-)
However, I must agree that performance on Mac OS X is still a major issue. Most applications ported to OS X are still, for the most part, a Classic Mac OS application that have simply got rid of several deprecated calls. This doesn't mean that they've been properly optimized. Most still use event managing software that's been around since the early 1990s. Instead of doing like a proper un*x app would and sleeping when it's not needed, these keep checking to see if they're needed [WaitNextEvent, for you Mac-programmer wireheads]. Apple has been trying to get people to move to the more processor-friendly carbon events, but it's (to use a buzzword) a major paradigm shift for your Mac programmer...instead of constantly asking the OS "Yeah, did I get any new events?" and then handling said event, now the OS tells the application "Hey, look alive, there's an event waiting for you."
I see a lot of promise in OS X, but it's going to need the programmers support to make it work well.
Personally, I don't think registering domains would be a viable or fun buisness for many people at this time. I mean, with putting up with angry customers saying "I want (fill-in-the-blank).com" and not being able to do anything about it would probably turn off many to this buisness. Also, with all the trademark problems with domain squatters &c. wouldn't be at all pleasing to deal with.
However, on the other hand, NSI isn't helping at all with the lack of.coms by holding on to them. I suppose it's a catch 22.
... but Aqua is itself basically one big theme file; if you remove it (or even switch resolutions on the fly;) you get a DP2-ish Platinum appearance.
I've heard that all that needs to be removed is a rsrc file that holds all the info on Aqua. Anyone happen to have instructions/how to on removing it? (Or know where to look?)
Yeah, and beyond the power-saving benefits of PowerPC, the old PowerBook 1400 used to have removable panels, I belive Apple called them "Book Ends." A third-party made a bookend with a solar panel that could be used to charge the battery. It was a tad pricey, but, hey, it was an idea whose time had come, and it battery power is always at a premium on a laptop.
It's good to see that this idea has come around again. I'm sick of getting only around 3 and a half hours on my laptop.
I'm sorry, I've got to disagree with you about moderation. Today for the first time, I got my moderator points. It felt like I was somehow giving back to slashdot. The good posts got some positives, and one or two really awful trolls got their posts about guzzling bodily fluids knocked down below most people's post reading levels. I realize some moderators can jump the gun with giving out bad points, but, hopefully, overall, these folks are cancelled out by those who actually care. If you don't like moderation, go ahead and view at -1. You'll get to see all the garbage that really isn't worth viewing anyway. Personally, though, I appreciate the system. I can only take so many hot grits jokes and links to awfully sickening pages. And it also helps to choose good posts to read when you're skimming along at slashdot on a lazy afternoon. And, by the way, I'd prefer an apple pie to the fries. What price does that come to?:-)
