Actually, it's users who are not following rules (assuming they have rules against using insecure telnet, which I'm sure they do):
The attacks start with the compromise of an unprivileged local user account. Usually this is because the attacker's captured the password from somewhere else: it's been sniffed off the network (through the use of insecure protocols like telnet), it's been collected when the user signs on to or from another compromised machine, it's been harvested from the password file on a compromised system.
So, we have user passwords as the source, which users freely give away by (1) using telnet instead of SSH, (2) just being very uninformed or gullible users, enough to plug in his/her unix password to a web form, and (3) once-removed version of (1) or (2) since these are just obtained from other compromised machines.
(1) and (2) are arguably the same problem, so that boils down to: users breaking rules -- surprise! But, that's easy to say, but hard to fix without more power. What to do? Seriously? Fine users for breaking rules?
This isn't Linux running on Windows or Windows running on LInux! It's fundamentally different, as in time-slicing the CPU:
port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine. For instance, it allows one to freely run Linux on Windows without using a commercial PC virtualization software such as VMware, in a way which is much more optimal than using any general purpose PC virtualization software.
So, I understand that to mean that the base OS is something that comes wtih CoLinux (master OS, or like a BIOS2, I guess) that divies up the machine resources among 2 OSes.
Er, I guess that's supposed to be funny (it's defninitely not ironic), but I have to point out that, obviously, you wouldn't have both desktops visible at the same time and position. Unless, I guess, you wanted to -- but you needn't, and most sane folks wouldn't.
Just in case you were serious (about being "ironic.")
Even with everything filled in, including the extra-hard CAPTCHA question, though admittedly I couldn't be bothered to look up the first one ("number of rods in a mile?" wtf?) so I refreshed until I got "20 - 1 = ?", but the error persists:

Doesn't seem like a slashdotting; it was quick enough to give me the less-than-helpful error message. What's the secret?
And the two easy countermeasures to your twop easy answers are:
1.) Split files into smaller chunks a la zip span, multisplitter, use perl to split, whatever. 1000 ways, and easy to automate both split and join,. See: Usenet.
2.) Set up a bucket-brigade to deliver from 1->2, 2->4, 4->8, etc. In no time your 0day warezes will be all over the globe. And that's with only 2 IP's per day! If it's useable without being annoying, it can be made to distribute efficiently enough (it's FREE! So it scales perfectly painlessly since 1 extra account = ZERO DOLLARS!)
Every preventative measure you can come up with I can hack it one-better(but I probably won't since I'm oh so tired:-D )
Working in Japan. She was supporting Sun (sales/marketing, though she's trained in law -- Japan employment is odd like that) in Tokyo, at NEC headquarters. I came to Japan for the first time as lead design engineer for the project I mentioned above to meet with the process engineers at the fab and show Sun's engineers a good time.
She was the first person I met there. Love. Instantly. As a tall blonde, I was like a rock star in the streets of Japan just based on looks, but I wanted nothing of the other (many beautiful) Japanese women I met (and could probably have chosen from at leisure). So, I hounded her for years with more than dozen trips to Japan, up to a month at a time. Brought her to visit the US a few times. Eventually she caved and married me, much to her family's chagrin.
We've been married for almost 3 years now and we couldn't be happier. I'm surprised she took the risk, but she loves it here. We just bought a nice house together, she doesn't have to work for us to do well, and her parents are starting to be less unhappy about the whole thing since we're doing well and not divorced already as they'd assumed we'd be.
I used to think all those songs and poems about love at first sight were bullshit, until I met her. Really.
I work for an ASIC vendor of Sun's (though I have an official Sun ID card/magnetic access thingy). I work pretty closely with the team that writes the RTL (specs the function) of the ASICs for which I do the physical design. They are part of an org that has such insane structure. Not me.
I would clean fish on my TPS cover sheets and everyone in my management chain knows it, for better or worse.
I wish you hadn't posted AC, though I understand why. I bet I know you, if you work(ed) in Sun Burlington. A lot of people there have privately expressed that sentiment to me. And there's a lot of truth to it based on my personal observations.
I've been working with the HESE (High-end Server Engineering) group there for almost 4 years making ASIC support chipsets for this cancelled SPARC program ("Eagle"). We had already taped out one, had the first design for another cancelled two years ago, and were 70-80% done with it's replacement (they switched from InfiniBand to PCI Express, which was smart, but resulted in tossing away about $80M in development and lots and lots of cancellation fees from my company.)
ASICs that should have taken 8-12 months tops were scheduled for 2+ year development cycles, then Sun's delays stretched that out even more. It was frustrating for me, since I spent a lot of time waiting for netlists and constraints, and aside from 2-3 key (lower-level) people I worked with who were competant, I saw so much waste and stupidity in the Sun management organization that I often got mildly depressed about it.
Their management is sorely lacking in hierarchy -- there are dozens of people with power to influence any decision (they are "stakeholders" as Sun calls them) yet never any one powerful enough to make a final decision, and many of these folks are too smart for the company good. Rather than pick a workable implementation and go with it, they would have meeting after meeting for months arguing about which way was "better". There was never any "main manager" who would step in and halt the endless nitpicking and force a decision. This delayed projects to an almost silly degree, and it's hard to believe how incessant it is unless you see it yourself.
So, just about everyone I worked with in Burlington was laid off. Some were given the chance to move to California to work on the SPARC stuff still going there, but most of their managers advised them that this program will also be cancelled within a few years, so unless they just wanted to go to California (few do), they should take the severance and run. Everyone I know did just that.
So, now the project I was working on for Sun that was cancelled and revived slightly differently once, is now completely cancelled. My company still got paid, but nothing like what we would have made had we gone to mass production (though even those forecasts were dropping steadily every year before cancellation). Worse, we had 60+ engineers in Japan and four here in Mass. devoted to Sun, and we even turned down some projects last year because we didn't have the engineering resources to handle them. Now we wish we had those back, and our sales staff are hustling to bring in some more work.
It just makes me sick, since I always thought of Sun as the great, innovative company, and I was so thrilled to be able to work with them (at first), and now they fall apart in front of my eyes.
On the bright side, I did get some great free trips to Japan and Australia on a extra-juicy expense account during the initial design win when we were wooing Sun every-which-way. Even met my wife on one trip to Japan. So it's not all bad for me, but it sure sucks for Sun.
I guess y ou don't get it. It will, indeed, be difficult for someone to explain to her the nature of the internet and the impossibility of completely removing anything from it. Especially considering her emotional state.
You missed my point (as did some others). I explained my post more thoroughly here.
The problem I have is that she (and her lawyers) are looking for a payday from this tragedy. She's going to extend her own sadness in the process, and someone, sometime, is going to have to have a very difficult conversation with her to explain (1) why she gets no money for her son's suicide and (2) why the genie can never be put back in the bottle. Those are valid points for discussion, since the gap in understanding between the tech-savyy and the not-so-savvy is widening, yet the net and the "real world" are intersecting more and more.
So, maybe now that you've called me a "dipshit" and a "prick" and added me to your foe list, perhaps you can read my explanation in the linked post and look at your incorrect assumptions in a different light. It might help you.
You completely misubderstood my post. It was not intended to be funny, and it bothers me that it was modded as such. I explained my original post more here.
For the record, I was born in a housing project and lived there until I was 13 (Blodgett Homes, downtown Jacksonville Florida off Union Street).
You had no idea how rich or poor I was born when you made that attack, BTW, so you might do well to pause and thing a bit yourself before making asinine assumptions based on some strange self-rightous bullshit proxy pity.
Wow, I guess I guess I should have explained my self more.
My comment was not meant to be funny at all, but in retrospect I can now see how some might find it somewhat funny in a macabre way that, again, was unintended. At first it was modded insightful. I was surprised and disturbed to see funny mods follow.
I did not mean to jab her for the use of "online" to mean the internet. It was a direct quote. Perhaps her use of the term helped some find this funny but, again, this was not my point.
As the AC wrote above the part that disturbs me is that she's apparently looking for a payday from this tragedy to be funded by "[whatever] killed [her] son the second time", so I smell a (misguided) wrongful death basis for a lawsuit against whomever her lawyers deem has the most liability and/or deepest pockets.
Even without my explanation above, I fail to see how you can fairly attribute a "m1573r l337" attitude to me or my post, or how I displayed any immaturity in it.
Maybe I didn't explain well enough my point, but I thought it obvious enough to be easily extracted by a thinking audience.
Why would they name it [Introducing: The Self-Cleansing Housing Projects.]?
I read the article (both actually -- sorry!). It seems that at least one of the websites that host(ed) the video has a racist leaning. And, presumably, they're trying to make a metaphor about young aspiring rap stars (or blacks in general if you prefer) to the effect that they are "trash" that needs to be cleaned from housing projects (as in be removed or killed).
Since this young man killed himself in the housing project of which he was a part (in a sense, since he lived there), according to the metaphor describe above, the housing project in question "cleaned" itself by removing (killing) this "trash".
Mods please note that those are not my sentiments in any way. I am just trying to help the parent understand the (apparently racist) footage title.
"It goes on, comes off, goes on. It's a joke," said Lane's mother. "That's why something has to come out of this hearing. I want my son's tape off that Web completely."
She's sad, distraught, angry , and confused. I'd hate to be the one that has to explain to her that you can never get anything "off that Web completely" once it's on.
raise incentives to purchase songs, like giving the Music Store a refreshed look
Eh? A "refreshed look" to a website will raise incentives to buy music, how?
Not a troll here; I just have to know what you were thinking or how I grossly misunderstood you. That, or your programming by the marketdroids is complete with better-than-expected results.
In the (sadly few) posts in this story I see an amazingly underwelming response to this achievement which, personally, I find rather amazing. Maybe it's because I've worked with image processing (CISP at Lockheed Martin during college) and appreciate how damn difficult reliable image recognition is, even when recognizing sub-images from a fixed (but still decently large) selection of image inputs.
IMHO this is one of the most clever and thorough hackings I've read about on/. in months. This is excellent work to solve a technically difficult problem in an unorthodox (and risky, in terms of complexity) way, and they do it with style (the commentary stuff is mint) and extensibility (the API is very open FWICT.) The only thing I lament is a lack of more detail (maybe that's the problem?), but I think the site has switched to simple static pages to minimize the slashdot effect (though probably not needed in this case) and I expect to be able to find more details
on a later visit.
And I'm afraid I must disagree with your notion that somehow it is a shame that it was so difficult to do. Necessity is the mother of invention, and here it shows (and pays off) in spades. What, are we supposed to rally against Nintendo (and all console makers, for that matter) for failing to provide a port with some open API to scan internal game variables? Frankly, I'd be way less impressed were they to in fact do that by either hacking onto the motherboard electrically, or worse running the game on an emulator (MAME or such) and peeking at RAM.
Nothing like making a developer's life hell by making them interface it like this.
Eh? These are not "developers" and no console maker expects antyone to want (much less implement) anything like this! They are hackers!
Again, I just want to say that I think this is one of the most underrated and under-commented yet excellent stories I've read here in a long time, and I plan to revisit the site later to learn more. This may be applicable to many other things from security cameras and home automation to MythTV-type device commercial skipping.
Then again, maybe I just don't realize how easy it is to do real-time image processing with object recognition in a reliable way using cheap under $50 capture cards on a 1GHz Athlon these days. Were that the case, though, I'd expect to read more about such efforts. This is a first for me.
Thanks for reading. And no, I do not know the authors(s) and I've never heard of this until now.
I agreed with a lot of your points, especially using welfare recipients for government labor (they do that in Mass. now, I think -- if you're on welfare long enough you just might find yourself sweeping floors at the courthouse to earn it).
As fun as it would be to see the error correction/redundancy you'd need, this is excessively labor-intensive. You can get a text dump of some kind from any database with known records. Perl the output into XML, merge, convert or import the result as needed, and use the labor to sweep the floors;)
Hey, go easy on the kid, he's already picked up two freaks because of this relatively minor little karma-whoring incident which yielded him only 1 karma point (the funny's don't matter) and no fans. I'm sure he's devastated enough already, and the mods may not be done with him yet;-)
At least he didn't paste in the entire article text without formatting, but including sidbear text ad copy interspersed, and then complain about how bad it sucked afterward.
I've seen it happen. And I haven't been here that long myself.
It may sit at 0.8V for a while (noise margin and all, but that's getting worked on as well, and I've heard of 0.6V stuff at TSMC), but if you think the only drop was 5V - 3.3V then you haven't been paying attention very well.
Again, this voltage drop has a much bigger impact than the increase in clock speed. 500MHz to 4GHz is only an 8x increase in power, all else the same. 3.3V to 1.0V voltage drop (which went along with that speed increase) amounts to an 11.89x decrease.
The overall increase in power you see and are erroneously trying to attribute to clock speed, is in fact more due to the total number of transistors on a die (~2M gates for a P2-450 up to more than 55M gates for a P4.) Each of these consumes F * C * V^2 Watts of power. Combine the gate increase (25x) and the clock increase (8x) and the ~2x drop in capactitance (due to shorter average wire length, smaller wire pitch, and lower gate capacitance) driven by each transistor, and you see an overall ~100x increase in power, but this is offset by a ~12x decrease due to voltage lowering, and that matches fairly well with the actual power increase of about 8-10x over the period in question. Note that the crudeness of these numbers that I rounded liberally are intended to show the scale more clearly without complicated formulae.
Of course, all that ignores leakage current (the discussion above relates to static current only), which is independent of clock rate, and depends only on voltage and physical process (increasing with decreasing geometries). Which further emphasizes the relatively low impact of clock rate on power compared to voltage.
Hope that helps.
Sorry if that sounds pedantic; I'm drunk. It happens.
Right, but if you're in that enlightened land of fantastic personal privacy protection that is the UK or other parts of socialist Europe, you'll have to hand over the keys to decrypt to the government or law enforcement on demand or face jail time.
But gmail keeping your v1ag4ra spam on file after you delete it is a much more pressing issue.
Feh. That is just as fucking stupid as the insanely moronic "toolbar" in the article, shamelessly whored by the asshat (rtmyers), who brought this little useles bastard of a "toolbar" into a meaningless, unwelcome existence without bothering to note that importanrt fact in his goddamn annoying little marketdroid pimp-speak sell-fest story text.
I want that 5 minutes of my life back and, judging from the other posts here, I could start a class action to try to get it. Of course, that would just end up with some lawyers living longer, which would be bad.
Switching power does indeed increase with clock speed (frequency, F) and capacitance (C), but it increases with the square of voltage (V), remember P = C * F * V^2.
As transistors get smaller, we indeed tend to switch them faster (bigger F), but we also suffer less parasitic capacitance (lower C) and, most importantly, we can run them at a lower voltage (lower V, which has a squared impact). That's why old 5V TTL logic eats a lot more power than modern 1.5V - 1.0V transitors.
But, as another poster already pointed out, as we get smaller transistors, there's less insulator to block current at the (smaller) gate, so previously--negligible leakage power increases as well.

Then again, maybe I just don't realize how easy it is to do real-time image processing with object recognition in a reliable way using cheap under $50 capture cards on a 1GHz Athlon these days. Were that the case, though, I'd expect to read more about such efforts. This is a first for me.
Thanks for reading. And no, I do not know the authors(s) and I've never heard of this until now.

I agreed with a lot of your points, especially using welfare recipients for government labor (they do that in Mass. now, I think -- if you're on welfare long enough you just might find yourself sweeping floors at the courthouse to earn it).
As fun as it would be to see the error correction/redundancy you'd need, this is excessively labor-intensive. You can get a text dump of some kind from any database with known records. Perl the output into XML, merge, convert or import the result as needed, and use the labor to sweep the floors
Hey, go easy on the kid, he's already picked up two freaks because of this relatively minor little karma-whoring incident which yielded him only 1 karma point (the funny's don't matter) and no fans. I'm sure he's devastated enough already, and the mods may not be done with him yet ;-)
At least he didn't paste in the entire article text without formatting, but including sidbear text ad copy interspersed, and then complain about how bad it sucked afterward.
I've seen it happen. And I haven't been here that long myself.
voltages seem to be staying fairly fixed these days since there hasn't been a fundamental shift like the one from TTL to CMOS
Eh? 1um-0.5um = 5V/3.3V; 0.35um - 0.25um = 3.3V/2.5V; 0.18um-0.15um = 1.8V-1.5V; 0.13um - 90nm = 1.1V - 0.9V; < 90nm = 0.8V.
It may sit at 0.8V for a while (noise margin and all, but that's getting worked on as well, and I've heard of 0.6V stuff at TSMC), but if you think the only drop was 5V - 3.3V then you haven't been paying attention very well.
Again, this voltage drop has a much bigger impact than the increase in clock speed. 500MHz to 4GHz is only an 8x increase in power, all else the same. 3.3V to 1.0V voltage drop (which went along with that speed increase) amounts to an 11.89x decrease.
The overall increase in power you see and are erroneously trying to attribute to clock speed, is in fact more due to the total number of transistors on a die (~2M gates for a P2-450 up to more than 55M gates for a P4.) Each of these consumes F * C * V^2 Watts of power. Combine the gate increase (25x) and the clock increase (8x) and the ~2x drop in capactitance (due to shorter average wire length, smaller wire pitch, and lower gate capacitance) driven by each transistor, and you see an overall ~100x increase in power, but this is offset by a ~12x decrease due to voltage lowering, and that matches fairly well with the actual power increase of about 8-10x over the period in question. Note that the crudeness of these numbers that I rounded liberally are intended to show the scale more clearly without complicated formulae.
Of course, all that ignores leakage current (the discussion above relates to static current only), which is independent of clock rate, and depends only on voltage and physical process (increasing with decreasing geometries). Which further emphasizes the relatively low impact of clock rate on power compared to voltage.
Hope that helps.
Sorry if that sounds pedantic; I'm drunk. It happens.
Copy and paste?
Duh.
Right, but if you're in that enlightened land of fantastic personal privacy protection that is the UK or other parts of socialist Europe, you'll have to hand over the keys to decrypt to the government or law enforcement on demand or face jail time.
But gmail keeping your v1ag4ra spam on file after you delete it is a much more pressing issue.
Wankers.
Feh. That is just as fucking stupid as the insanely moronic "toolbar" in the article, shamelessly whored by the asshat (rtmyers), who brought this little useles bastard of a "toolbar" into a meaningless, unwelcome existence without bothering to note that importanrt fact in his goddamn annoying little marketdroid pimp-speak sell-fest story text.
I want that 5 minutes of my life back and, judging from the other posts here, I could start a class action to try to get it. Of course, that would just end up with some lawyers living longer, which would be bad.
Jumped the shark, slashdot has.
when you drop the clock frequency of a processor its power requirements drop still faster
Er, no. Perhaps you were thinking of voltage? Switching power varies linearly with frequency and capacitance. It varies with the square of voltage.
P(switching) = F * C * V^2
Switching power does indeed increase with clock speed (frequency, F) and capacitance (C), but it increases with the square of voltage (V), remember P = C * F * V^2.
As transistors get smaller, we indeed tend to switch them faster (bigger F), but we also suffer less parasitic capacitance (lower C) and, most importantly, we can run them at a lower voltage (lower V, which has a squared impact). That's why old 5V TTL logic eats a lot more power than modern 1.5V - 1.0V transitors.
But, as another poster already pointed out, as we get smaller transistors, there's less insulator to block current at the (smaller) gate, so previously--negligible leakage power increases as well.
