If I think of a cool name, and its available I generally snag it. Since I register so many domains for clients I get a really good bulk deal with my registrar. Most TLD's cost me less than $5 to get.
I use sedo, and have had some success moving them. I've received a few offers on some over the $1k range but want to see what else comes in.
I looked at it like this. The domain trade business is quite a bit like the playing lotto once or twice a week business, with approximately the same chances that you'll hit the jackpot.
Average lotto player spends about $10 - $15 a week on tickets, roughly $50 - $60 a month. I register about 10 domains a month.
Services like sedo allow you to park your domains, drive traffic to them and collect on a share of the PPC programs they use on the parking page, plus get offers on your domains. Helps build up Alexa traffic scores to increase the value.
Each parked domain makes me about $3 a week. So after having a domain a month not only does my little hobby not cost me anything, I make a couple of bucks in the process. I'm not getting rich doing this by any means, but my 200 or so domains pay for neat stuff like r.c. parts and model kits.
I never register one with the idea that I'm just going to sell it, usually I do intend to develop the domain into something. The parking just lets me afford to move a little slower "getting around to it".
Its turned into a fun hobby that helps pay for my other hobbies. The point is now my significant other can't really say much if I go out and blow a few hundred bucks on a nice meter or a couple old clunker linux boxes to play with (and the electric bill they tend to make).
If you go register dozens of domains today with the idea that you'll get rich, you'll be sadly disappointed. But like the lotto, there is that 1 in (some huge number) chance you'll strike gold. Treat each one just like a lotto ticket, potentially worthless.
I was just in China (Macau) which is the most lightly regulated administrative district in China.. and you do *not* get images of tank man.
Censoring is done based on IP, and open or transparent proxies are being locked down and stuffed. I was curious, so I fired up Google from the hotel.
While these measures do / will cut down on the abuse my networks get (a good 60% comes from China).. this is not the internet I helped to build.
Why can't they just make a law requiring abuse departments to answer the damn requests under penalty of public tar and feathering?
Looks like the Chinese who want free speech on line are going to have to resort to what we did in the old days with WWIVNet and FIDONet - shortwave / ham with modulation. Slow, but effective. Where there's a will there's a way:)
Cut a ping pong (table tennis) ball in half. Place the cut side down on a piece of paper. Draw a circle around the now halved ping pong ball on the paper.
>> True...but what about the driver of the vehicle you are crashing into? It would pretty well suck for him. Also if both vehicles has this it might actually make car wrecks worse all around.
I was thinking about the reinforcing Volvo does in the door panels for side impact protection. Something that crumpled a bit but didn't pierce is what I had in mind. I thought about the effect on the other vehicle.
My idea would be to simply shield the driver / passenger by reinforcing the crumple zones. That should not have any more effect on the other vehicle than the existing reinforcing does, but I'm not an engineer.
Doesn't have to be iscsi that's just what we're using because its simple. As far as the netfs , anything you can put into the 2.6 kernel will work. We figured on a local gig-e network over copper which is why we're using iscsi for developing it.. but by no means is it built 'around' iscsi.
It could be made to work with just about anything. That's the other part of why it's taking so long to do. But yes, you could accomplish that.
Bear in mind the definition of high availability is no single point of failure. So if each machine had just 1 physical nic, though you could simulate 2.. you still have that bottleneck and potential point of failure. Your power supply is also a single point of failure. If you just want basic redundancy than what you have will work as long as you have gig-e nics and a switch supporting it.
Any time you are working off a SAN you may also want to contemplate using a local disk (SATA or SCSI) for local swap depending on the applications and how much memory you're willing to give them. That just makes sense.
I also really can't call it 'our' software. We did not write openSSI nor Xen.. all we're doing is putting them together and simplifying management of both, then combining them in a way thats practical to do what you want. Most of it will be open sourced once its stable enough to release so we can get more developers working on it.
A RAIH is available now, with the pros and cons I listed. What's lacking is the ultra neat spiffy cool idiot proof management console. When we release you can bet some very knowledgable skeptics are going to aim to tear it to shreds.. I mean thats a guarantee. So we're trying to do that ourselves in the development stage as we go, even if it means some major drop-back-and-punts.
You could do want you want right now with just the Xen SSI kernels , Debian and a knowledge of how to play with CVIP and HA-LVS. Once you grasp those you'll see how easy it would be to script what you want. I don't think it will be long until you see something (or many somethings) like this hitting the commercial market.
We plan to go the open source route as custom configurations would pay for and allow us to profit from the time / money that's gone into it (well, we hope, anyway).. but just can't see charging for what's 80% open source to begin with. That's a little too close to squatting.
When I see something like this of course my brain starts to pick apart how it may work and what went into it. TFA didn't mention much about what was controlling it.. however this is my guess:
Damn I wish I got paid to make stuff like that. Anyone find any other info giving more detail as to exactly what went into that system? This would be an invaluable safety system on vehicles, if nothing less just shielding the driver from the initial crash.
* Total centralized command * Dynamically provision / reprovision based on application demand, roles and rule sets * paranoid sanity checks * use, but don't force LVM. Make use of just conventional images. * Integrate HPC's that can be dynamically reprovisioned.
This is done with Xen + openSSI. In a case like yours it would not be a conventional single system image, you'd be using a couple redundant wasabi style NAS's, which can also be built with Xen for additional failover, storing many images and running a few separate director nodes pulling from various places.
Drawbacks :
* Xen 3 is still very beta so we're using xen 2, which has a memory cap. * You really get stuck with just using iscsi for it to be practical over copper * Vlans get a bit confusing, but are accomplishable (i.e/29 on one end/32 on the other) * You need to be really comfy patching the 2.6 kernel * Adding Win2k3 into the mix for provisioning will require xen 3 and mass stability, which is in sight.. but still kind of far out on the horizon. * Xen's balloon driver is still not quite perfected. * Depending on what you push latency could be a small, but over-comeable issue.
It utilizes CVIP / HA-LVS and the loadleveling inherent in openSSI to accomplish this.
What we're doing doesn't exactly fit your need, but could with a little work. There are at least a dozen small companies that have been following and playing with Xen working on something nearly identical. What takes forever to account for is 'the better idiot'. There are just so many possible configurations.
If you want to tinker check into Xen + openSSI , there's a wealth of info regarding it and even some setup scripts for it in the works. Many people want the exact same thing, including me:)
Correct. I work with Xen daily and most of my products and services are built around it. One of which is a replacement for Virtuozzo for the purposes of maximizing and isolating resources or web hosting companies.
Xen augments the kernel, it does not replace it. The Xen hypervisor then interacts with the host (dom-0) kernel.
dom-u (guest) images can then boot using any kernel modified to interact with the Xen hypervisor. Currently we play with:
Debian (Sarge) FC4 CentOS 4 NetBSD
As dom-u's (guest) OS's.
We have also enjoyed some success but not 100% stability bringing Win2k3 up as a dom-u.
I have deployed clusters that use Xen as a management layer and I can tell you, it *does* live up to its marketing specs. Xen's bridging is the fastest most efficient layer available, bar none. Its also a wonderful tool in helping to integrate a centralized storage area network into any size network and let people keep all of the protocols they like.
A *very* good source of information about Xen, what it does, how it does it is available on the option-c wiki (Here) , they also have some ready to go Debian installers that make installation quite easy (apt-get able).
Xen + OpenSSI is another fantastic combination if you take the time to really understand the networking possiblities and set it up appropriately. Good luck with the bean counters.. the price is right:)
>>
The article doesn't even touch on Intel's VT or AMD's Pacifica technologies. What gives? >>>
Or being able to have win2k3 happily running as a dom-u under Xen 3 on such hardware. There's only so much you can fit in a one page blurb however. And the average reader wants it all compressed into 5 minutes or less of reading.
Topics like this , you just can't do that unless you link to many external resources allowing the reader to get more about whatever interests them.. which is what TFA should have done.
But it comes quite a bit closer to being a down to eart overview than many others on the same topic that I've read.
I re-read it a few times just to be sure. Its not very well constructed, but I think I got the context right in my post.. I think. Read it this way swapping a space with a new line:
If you're a developer looking for a flexible way to test your application in multiple environments, you'll probably want to go with either Virtual PC or VMware Workstation.
If you want to use Linux as your host OS, you'll definitely have to go with VMware.
The way that reads to me is, if you want to use Linux as your host (root) OS , you have no choice but to go with VMWare. What about Xen?
You almost need to read it out loud. Not the best constructed article. I had to do a couple double takes just to be sure after reading your comment.. but I think I got the right meaning and didn't twist the context.. wasn't my intention to do so. It seemed pretty clear the first time I read it, unless I'm missing something? I am rather dense prior to my 6'th cup of coffee and only on #4 right now so please do reply if I'm way off base..
While TFA did annoy me at the end you have to admit its a very broad and difficult topic to cover in a way that pleases everyone. Most similar articles I've read get lost just in the 'how it works' section.
People who understand Virtualization aren't going to rely on this type of article to make decisions, they tend to prefer whitepapers and case studies. Someone without the benefit of experience is going to lean heavy on Google to find a solution.
There's just no way to cover everything that can be covered without losing the average reader. This one didn't go too terribly in depth and touched on some good points and really tried to educate the reader, up until the end.
From TFA: >>>>>
Novell is investing lots of effort in optimizing Xen specifically for running a virtualized copy of NetWare on top of Linux. The company's goal is to provide its customers with a migration path over to the Linux platform without giving up NetWare. >>>>>
One of the many un-sung uses for Xen is a swiss army SAN. I'm glad to see someone touch on this.
>>>>> If you want to use Linux as your host OS, you'll definitely have to go with VMware. >>>>>
That wasn't so cool. I appreciate the fact that there are just too many products available to touch on everything in one short summary article / writeup, and while the majority of the article was informative even to the lay person, you need to end a sentence like that with a 'Because.... [summary]'. That's a really broad and sweeping statement to make.
Or perhaps even "I recommend VMWare" would have been better.
It looks like the author lost interest in what they were writing near the end of the article. They talk about IRC or newsgroups being the only support options available for OS products [another sweeping statement], however have you checked out the wiki at xensource.com lately?
Just seems like TFA lost coherency after 'What's best?' It went from really informative to misleading rather quickly. If your going to go to a virtualized platform you owe it to yourself to spend a month trying each candidate to see what works best for you, not the author of whatever article you read:) This is not a pro Xen rant but I'd like to point out that it does install effortlessly on most Debian systems in under an hour, the TFA sort of indicated otherwise.
>> This is wrong or at best, misleading. Online advertising continues to grow. New publishers succeed. New niches are discovered. Competition increases but online advertising continues to florish. >>
I should have been more specific in the post. Niche markets (as far as I see, and I deal with quite a few in the business) are the only ones doing well. My point is news sites for the most part do not cater to any niche. I talked a little too late in the post about other means to hit niches and boost the overall success of the site.
>> Welcome to yesterdays news. Doorway pages do not work. Pumping out content is over. Quality content however is still king. >>
Exactly. However the competition for the same content is immense. News breaks and everyone reports it. You don't just want visitors, you want conversions - meaning someone has to find you AND click an ad. Re-wording headings and trailers to suit SE's may get you found more often, but is going to reduce your likelyhood of converting. Now you've wasted bandwidth.
News papers are written for a 6'th grade or better reading level and most journalists know you have to write for the largest audience you can get. The heading / title is your best chance to get it and now it looks like that's going to a second grade (search engine) reading level. I think they'll find they get the opposite result than expected.
>> So what you're saying is if your site is not SEO friendly then don't bother improving it? Or are you saying change your keyword titles? I'm confused.
Making well crafted semantically correct HTML is a no brainer if you publish news. My point was do what you can without making it obvious and seek alternetive marketing. Radio ads are a wonderful way to get people to your web site. They won't rush home and pull up your page however your URL if repeated will stick in their mind and if easy to remember will be put directly into their browser bar. - and was just one example of another way to reel in conversions.
>> Better synonym matching and semantic improvements could help this situation so maybe we should blame this on inferior search engines?
Yes, and Google adsense (among others) who makes it profitable to put up complete junk that gets indexed well. Now its becoming a trend and saturation is getting to be a major problem. Its the junk article wikis , not news sites that are to blame (imho). I live in Manila where this dirty laundry gets outsourced and I hear no less than 50 ads a day on the radio for SEO content writers, and its only picking up. Imagine a big fat sponge that just won't hold any more.
I see a tidal wave coming that isn't quite visible from a state side vantage point. It's only going to get worse for them.. if I were a news publisher.. I'd be taking my eggs out of the Google basket and finding somewhere else to put them:)
The only ones profiting no matter what soon are going to be the popular contextual ad networks that are known to pay accurately and on time.
This vision of subtle bioweapons that modified behavior by targeting the nervous system -- inducing effects like temporary schizophrenia, memory loss, heightened aggression, immobilizing depression, or fear -- was irresistibly attractive to Biopreparat's senior military scientists.
So how's that different from rush hour traffic in or around the Washington DC I-495 beltway loop? Seems our boys at NSA haven't got containment down just right yet.
I think (as many have stated already) NASA knows its in trouble. I took a look myself and honestly, I feel kind of bad for them.
* They have no money to launch missions * They have no (significant) money for R&D * They have no money to hire the brains it takes to overcome problems they face * They have no money to hire managers that can bring in projects successfully
Even though they remain operational they are kind of crippled. They just don't have the money to do the stuff they were created to do. So all they can really do now is tinker with what is already deployed and come up with cheaper ways to do more unmanned explorations..
So its no doubt that an outreach program is being formed. Regardless of your opinions on green house gases, conservation, over population, etc - any reasonable person must realize somewhere in the back of their mind that we aren't too far away from out growing our space rock. We need NASA to work.
Of course they're reaching out to kids , those kids will be graudating from college right around the time that most of their funding finally gets cut off if current trends continue.
I wonder why they did not partner with educators *first*. Remember that old movie 'space camp' ? I think more hands on experiences would serve the purpose better - however those cost quite a bit more and you have to bring the kids there. Science + Economics just don't mix, and they're going about the science OF economics the wrong way, any logical person would.
I hope we don't see E.T. santas this year standing next to the Salvation Army guys holding out astronaut helmets riging bells - but if they don't get funding soon from somewhere that's where it could be headed.

I use skiplinks which I don't display inside of graphical browsers,.skipLinks {display: none;}
However they are just anchored links to the areas of my page, i.e. content, header, footer and navigation.
I use them for easy linking from other pages, so I can cut down on the amount of anchored links inside of the respective sections. It's more for lazyness and organization than SEO.
They also help on the odd chance someone is using a text based browser to view my pages, right up top so only a few arrow strokes in Lynx gets you where you want to go.
Google doesn't mind you making your site organized and inter-operable. They do mind it when you attempt to add content for SEO value that is not visible to someone who would visit your page under normal circumstances. This is called "cloaking" (even though you aren't using some application to generate content just for Google) and will get you banned quickly.
Used to be to start a fire you took two sticks of about the same size and.....
We don't do that anymore. Just like companies that hope to market their news agencies have got to stop depending on search engines to reel in traffic. The sites that attract visitors through searches and make revenue by serving ads are established and have consumed the available market share.
To be successful doing what they do, one of them has to go under right around the time you have something similar already seeding in search engines. Its quite a long waiting list folks.
If you want to reach a niche news market you need to hit people during rush hour in their cars with radio advertisements, or find another way of luring them to your site and when they arrive your titles had better not be crafted for Google.
Look at the explosion of over a million.eu domains, many of which are going to be those article-wiki type affiliate marketing sites and search engines are already crawling them. Sorry guys, but the days of putting up hundreds of pages of content and waiting for Google to do your marketing are gone.
Don't re-write the titles, take the hint that what you're doing just isn't working. Either change your marketing strategy or re-evaluate the fiscal sanity of continuing to publish.
Insanity is doing the same thing over, and over and over again yet expecting different results. The market is flooded - get creative in your advertising and MORE creative with your content and you may enjoy some success. Otherwise the sad fact is.. nobody is going to find you.
Go take a look at shitlance and search for "need articles, need articles re-written, SEO content author". Trying to succeed doing what they're doing is like punching yourself in the nuts until you pass out.
AHA! Found it. It was the 65CE02 which had an on chip clock which you could send a trigger to stop, causing the MP to go into a suspended but wake-able state (and from 5v to 1.5v consumption). When the clock resumed via external trigger, so did the MP without having to go through its full start up cycle. They never did much with it oddly.
When I read the article what popped into mind was low consumption while doing nothing, which is what made me think of it. So now I've shown my age and made quite the ass of myself, but what else is/. for?
So not the same thing. Sorry for the ruccus:) Hey I'm amazed I even remembered it:P
Handy PDF giving the 3 clock options for the 6500 series that commodore used. I can't however find a datasheet specifically for the transitional 6502 they used when going from the VIC-20 over to the first Commodore 64 which was the one I was thinking about.
However if the prior, and latter models used an external or on chip clock, I'd imagine so does the one I was thinking of.
I remember reading about a clockless MP they were putting into production and I can't remember the name of it. This is going to bother me.
Correct me if I'm wrong, I could be however if I am not mistaken, the early 6502 microprocessor used in Commodore 64 (and in later made VIC-20's) did not have a clock or need one.
However I could be mistaken, and info related to the 6502 is a little hard to come by. Plenty of it from hobbyists however not all entirely accurate, and reaching CBM these days to ask is a little difficult;)
I think they're still in use in positioning devices that point things like satellite dishes and on microwave hops that auto correct their azimuth in really windy areas.
If someone has a commie gathering dust (or better the owner's manual) the exact specs and power consumption should be on the very back page. I wish I still had mine. If you have one, pls reply and let me know if I'm right.. its now bothering me:D I know commodore made a small MP that did not have a clock core or use anything external. I'm just not sure if it was the 6502.
I think the whole point of the 'project' was to show that older hardware still had usefuless to some people, though useless to most. Mostly to (I think) try to convince people to get off their duffs, go out to the garage, grab those two old desktops and drop them off some place that could use them.
And don't forget Linux people tend to do things simply because they can. However I agree this is not great feat. This was plugging in a bunch of computers to a switch tossing in some CD's and powering up the boxes.
I once toyed around with some ULV p3 SBC's that I got in a lot. Nice low profile ones with a CF socket, all kinds of I/O risers and 2 on board nics. 5V at a pretty low draw, I was going to use some photovoltaic cells and some marine batteries to make a little eco cluster. CF is large enough (came with each one) to hold an etherboot setup / initrd and each one can handle 2 x 256 SODIMMs. May still do it if I can find a free weekend.. and the SODIMMs cheap enough.
If any applause is warranted, shoot over to the Parallel Knoppix site and drop the author a line.. he's doing some interesting things and is really enthused about his project. I host the only US mirror for k-pix, he could use some more.
Point being (and yep I have one) don't just post about how bad someone else's idea was.. enjoy yourself some and tinker with your own:) Nothing wrong with taking some time to do something completely senseless if you enjoy it.
I was kind of intriuged by TFA so I did a little poking around on sites I knew off hand sold OEM naked boxes. However, I had a little trouble finding a place that would sell me something with no OS loaded, most are insisting you at least get something like DR-DOS (or slackware) just so they can ensure the thing boots - quite understandable.
Then I fired up google groups and did a bunch of browsing around the hardware groups, and Linux groups.. and places I thought I may find people talking about their brand new inexpensive or custom boxes.
Every single one I found was pieced together in a custom config, or bought specifically for use as a Linux box. Over half I read (I sifted through about 20 posts) described going to several local stores to get everything in pieces to save money or get exactly what they wanted, or ordering components from a few different sites.
What this tells me is OEM's not offering MS products are not likely to lose market share as they compete in a different niche market, one MS doesn't seem to be able to touch.
So in conclusion I think this is from the 'if-you-can't-beat-em-try-to-null-their-market' dept , but is (at best) a feeble attempt from MS to do so.
What is rather disconcerting is the spin that was put on it, which could (possibly) help MS in their effort to take a bite out of that market as it does nothing but seed paranoia. Did/. get bought out by Fox news?
I know its/. - but nobody likes being mislead - and I'm guessing a few small PC shops lost a few sales. Nice going.
I looked for, but could not find any conclusive statistics that indicate if people who want a naked PC would be more likely to acquire parts and simply build it themselves.
I'd like to see those statistics (if they exist) before I completely dismiss the validity of the article.. but coming from a conspiracy nut (I'm one of the biggest) I'm inclined to agree and say..
bullshit.
It looks like this was aimed not at people who sell OEM (bare) as just an option, but people who don't offer Windows licensing at all.. and a warning that they'll lose market share.
Gestapo-ish marketing, yes. Big brother... I don't think so. And I'm no fan of Microsoft.

Once you grasp those you'll see how easy it would be to script what you want. I don't think it will be long until you see something (or many somethings) like this hitting the commercial market.
We plan to go the open source route as custom configurations would pay for and allow us to profit from the time / money that's gone into it (well, we hope, anyway)
When I see something like this of course my brain starts to pick apart how it may work and what went into it. TFA didn't mention much about what was controlling it .. however this is my guess:
LynxOS
Damn I wish I got paid to make stuff like that. Anyone find any other info giving more detail as to exactly what went into that system? This would be an invaluable safety system on vehicles, if nothing less just shielding the driver from the initial crash.
I've got this *kinda* done. This was our goal:
/29 on one end /32 on the other) .. but still kind of far out on the horizon.
:)
* Total centralized command
* Dynamically provision / reprovision based on application demand, roles and rule sets
* paranoid sanity checks
* use, but don't force LVM. Make use of just conventional images.
* Integrate HPC's that can be dynamically reprovisioned.
This is done with Xen + openSSI. In a case like yours it would not be a conventional single system image, you'd be using a couple redundant wasabi style NAS's, which can also be built with Xen for additional failover, storing many images and running a few separate director nodes pulling from various places.
Drawbacks :
* Xen 3 is still very beta so we're using xen 2, which has a memory cap.
* You really get stuck with just using iscsi for it to be practical over copper
* Vlans get a bit confusing, but are accomplishable (i.e
* You need to be really comfy patching the 2.6 kernel
* Adding Win2k3 into the mix for provisioning will require xen 3 and mass stability, which is in sight
* Xen's balloon driver is still not quite perfected.
* Depending on what you push latency could be a small, but over-comeable issue.
It utilizes CVIP / HA-LVS and the loadleveling inherent in openSSI to accomplish this.
What we're doing doesn't exactly fit your need, but could with a little work. There are at least a dozen small companies that have been following and playing with Xen working on something nearly identical. What takes forever to account for is 'the better idiot'. There are just so many possible configurations.
If you want to tinker check into Xen + openSSI , there's a wealth of info regarding it and even some setup scripts for it in the works. Many people want the exact same thing, including me
Correct. I work with Xen daily and most of my products and services are built around it. One of which is a replacement for Virtuozzo for the purposes of maximizing and isolating resources or web hosting companies.
.. the price is right :)
Xen augments the kernel, it does not replace it. The Xen hypervisor then interacts with the host (dom-0) kernel.
dom-u (guest) images can then boot using any kernel modified to interact with the Xen hypervisor. Currently we play with:
Debian (Sarge)
FC4
CentOS 4
NetBSD
As dom-u's (guest) OS's.
We have also enjoyed some success but not 100% stability bringing Win2k3 up as a dom-u.
I have deployed clusters that use Xen as a management layer and I can tell you, it *does* live up to its marketing specs. Xen's bridging is the fastest most efficient layer available, bar none. Its also a wonderful tool in helping to integrate a centralized storage area network into any size network and let people keep all of the protocols they like.
A *very* good source of information about Xen, what it does, how it does it is available on the option-c wiki (Here) , they also have some ready to go Debian installers that make installation quite easy (apt-get able).
Xen + OpenSSI is another fantastic combination if you take the time to really understand the networking possiblities and set it up appropriately. Good luck with the bean counters

The article doesn't even touch on Intel's VT or AMD's Pacifica technologies. What gives?
>>>
Or being able to have win2k3 happily running as a dom-u under Xen 3 on such hardware. There's only so much you can fit in a one page blurb however. And the average reader wants it all compressed into 5 minutes or less of reading.
Topics like this , you just can't do that unless you link to many external resources allowing the reader to get more about whatever interests them.. which is what TFA should have done.
But it comes quite a bit closer to being a down to eart overview than many others on the same topic that I've read.
I re-read it a few times just to be sure. Its not very well constructed, but I think I got the context right in my post .. I think. Read it this way swapping a space with a new line:
.. but I think I got the right meaning and didn't twist the context.. wasn't my intention to do so. It seemed pretty clear the first time I read it, unless I'm missing something? I am rather dense prior to my 6'th cup of coffee and only on #4 right now so please do reply if I'm way off base ..
If you're a developer looking for a flexible way to test your application in multiple environments, you'll probably want to go with either Virtual PC or VMware Workstation.
If you want to use Linux as your host OS, you'll definitely have to go with VMware.
The way that reads to me is, if you want to use Linux as your host (root) OS , you have no choice but to go with VMWare. What about Xen?
You almost need to read it out loud. Not the best constructed article. I had to do a couple double takes just to be sure after reading your comment
While TFA did annoy me at the end you have to admit its a very broad and difficult topic to cover in a way that pleases everyone. Most similar articles I've read get lost just in the 'how it works' section.
People who understand Virtualization aren't going to rely on this type of article to make decisions, they tend to prefer whitepapers and case studies. Someone without the benefit of experience is going to lean heavy on Google to find a solution.
There's just no way to cover everything that can be covered without losing the average reader. This one didn't go too terribly in depth and touched on some good points and really tried to educate the reader, up until the end.
So good reading, for this type of article.
From TFA:
.... [summary]'. That's a really broad and sweeping statement to make.
:) This is not a pro Xen rant but I'd like to point out that it does install effortlessly on most Debian systems in under an hour, the TFA sort of indicated otherwise.
>>>>>
Novell is investing lots of effort in optimizing Xen specifically for running a virtualized copy of NetWare on top of Linux. The company's goal is to provide its customers with a migration path over to the Linux platform without giving up NetWare.
>>>>>
One of the many un-sung uses for Xen is a swiss army SAN. I'm glad to see someone touch on this.
>>>>>
If you want to use Linux as your host OS, you'll definitely have to go with VMware.
>>>>>
That wasn't so cool. I appreciate the fact that there are just too many products available to touch on everything in one short summary article / writeup, and while the majority of the article was informative even to the lay person, you need to end a sentence like that with a 'Because
Or perhaps even "I recommend VMWare" would have been better.
It looks like the author lost interest in what they were writing near the end of the article. They talk about IRC or newsgroups being the only support options available for OS products [another sweeping statement], however have you checked out the wiki at xensource.com lately?
Just seems like TFA lost coherency after 'What's best?' It went from really informative to misleading rather quickly. If your going to go to a virtualized platform you owe it to yourself to spend a month trying each candidate to see what works best for you, not the author of whatever article you read
>> This is wrong or at best, misleading. Online advertising continues to grow. New publishers succeed. New niches are discovered. Competition increases but online advertising continues to florish. >>
.. I'd be taking my eggs out of the Google basket and finding somewhere else to put them :)
I should have been more specific in the post. Niche markets (as far as I see, and I deal with quite a few in the business) are the only ones doing well. My point is news sites for the most part do not cater to any niche. I talked a little too late in the post about other means to hit niches and boost the overall success of the site.
>> Welcome to yesterdays news. Doorway pages do not work. Pumping out content is over. Quality content however is still king. >>
Exactly. However the competition for the same content is immense. News breaks and everyone reports it. You don't just want visitors, you want conversions - meaning someone has to find you AND click an ad. Re-wording headings and trailers to suit SE's may get you found more often, but is going to reduce your likelyhood of converting. Now you've wasted bandwidth.
News papers are written for a 6'th grade or better reading level and most journalists know you have to write for the largest audience you can get. The heading / title is your best chance to get it and now it looks like that's going to a second grade (search engine) reading level. I think they'll find they get the opposite result than expected.
>> So what you're saying is if your site is not SEO friendly then don't bother improving it? Or are you saying change your keyword titles? I'm confused.
Making well crafted semantically correct HTML is a no brainer if you publish news. My point was do what you can without making it obvious and seek alternetive marketing. Radio ads are a wonderful way to get people to your web site. They won't rush home and pull up your page however your URL if repeated will stick in their mind and if easy to remember will be put directly into their browser bar. - and was just one example of another way to reel in conversions.
>> Better synonym matching and semantic improvements could help this situation so maybe we should blame this on inferior search engines?
Yes, and Google adsense (among others) who makes it profitable to put up complete junk that gets indexed well. Now its becoming a trend and saturation is getting to be a major problem. Its the junk article wikis , not news sites that are to blame (imho). I live in Manila where this dirty laundry gets outsourced and I hear no less than 50 ads a day on the radio for SEO content writers, and its only picking up. Imagine a big fat sponge that just won't hold any more.
I see a tidal wave coming that isn't quite visible from a state side vantage point. It's only going to get worse for them.. if I were a news publisher
The only ones profiting no matter what soon are going to be the popular contextual ad networks that are known to pay accurately and on time.

This vision of subtle bioweapons that modified behavior by targeting the nervous system -- inducing effects like temporary schizophrenia, memory loss, heightened aggression, immobilizing depression, or fear -- was irresistibly attractive to Biopreparat's senior military scientists.
So how's that different from rush hour traffic in or around the Washington DC I-495 beltway loop? Seems our boys at NSA haven't got containment down just right yet.
I think (as many have stated already) NASA knows its in trouble. I took a look myself and honestly, I feel kind of bad for them.
..
* They have no money to launch missions
* They have no (significant) money for R&D
* They have no money to hire the brains it takes to overcome problems they face
* They have no money to hire managers that can bring in projects successfully
Even though they remain operational they are kind of crippled. They just don't have the money to do the stuff they were created to do. So all they can really do now is tinker with what is already deployed and come up with cheaper ways to do more unmanned explorations
So its no doubt that an outreach program is being formed. Regardless of your opinions on green house gases, conservation, over population, etc - any reasonable person must realize somewhere in the back of their mind that we aren't too far away from out growing our space rock. We need NASA to work.
Of course they're reaching out to kids , those kids will be graudating from college right around the time that most of their funding finally gets cut off if current trends continue.
I wonder why they did not partner with educators *first*. Remember that old movie 'space camp' ? I think more hands on experiences would serve the purpose better - however those cost quite a bit more and you have to bring the kids there. Science + Economics just don't mix, and they're going about the science OF economics the wrong way, any logical person would.
I hope we don't see E.T. santas this year standing next to the Salvation Army guys holding out astronaut helmets riging bells - but if they don't get funding soon from somewhere that's where it could be headed.
Well it started off as a 4, now its a -1 .. so looks like someone called all of their buddies "HEY, you got mod points? Go mod this down .. " , thats just .. pathetic.
.. welp nobody will read it because the nazi regs don't agree with what you have to say. /. really needs to work on their mod system. I have 5's that should be 1's and -1's that should be 4's - and its consistently botched.
It pisses me off because I spent time contributing, and now most people won't see it. I don't post just for the sake of doing it, I work in the business of helping people make sites successful and had some things to share.

I use skiplinks which I don't display inside of graphical browsers, .skipLinks {display: none;}
However they are just anchored links to the areas of my page, i.e. content, header, footer and navigation.
I use them for easy linking from other pages, so I can cut down on the amount of anchored links inside of the respective sections. It's more for lazyness and organization than SEO.
They also help on the odd chance someone is using a text based browser to view my pages, right up top so only a few arrow strokes in Lynx gets you where you want to go.
Google doesn't mind you making your site organized and inter-operable. They do mind it when you attempt to add content for SEO value that is not visible to someone who would visit your page under normal circumstances. This is called "cloaking" (even though you aren't using some application to generate content just for Google) and will get you banned quickly.
Used to be to start a fire you took two sticks of about the same size and .....
.eu domains, many of which are going to be those article-wiki type affiliate marketing sites and search engines are already crawling them. Sorry guys, but the days of putting up hundreds of pages of content and waiting for Google to do your marketing are gone.
.. nobody is going to find you.
We don't do that anymore. Just like companies that hope to market their news agencies have got to stop depending on search engines to reel in traffic. The sites that attract visitors through searches and make revenue by serving ads are established and have consumed the available market share.
To be successful doing what they do, one of them has to go under right around the time you have something similar already seeding in search engines. Its quite a long waiting list folks.
If you want to reach a niche news market you need to hit people during rush hour in their cars with radio advertisements, or find another way of luring them to your site and when they arrive your titles had better not be crafted for Google.
Look at the explosion of over a million
Don't re-write the titles, take the hint that what you're doing just isn't working. Either change your marketing strategy or re-evaluate the fiscal sanity of continuing to publish.
Insanity is doing the same thing over, and over and over again yet expecting different results. The market is flooded - get creative in your advertising and MORE creative with your content and you may enjoy some success. Otherwise the sad fact is
Go take a look at shitlance and search for "need articles, need articles re-written, SEO content author". Trying to succeed doing what they're doing is like punching yourself in the nuts until you pass out.
Completely *wrong* direction, imho.
AHA! Found it. It was the 65CE02 which had an on chip clock which you could send a trigger to stop, causing the MP to go into a suspended but wake-able state (and from 5v to 1.5v consumption). When the clock resumed via external trigger, so did the MP without having to go through its full start up cycle. They never did much with it oddly.
/. for?
:) Hey I'm amazed I even remembered it :P
When I read the article what popped into mind was low consumption while doing nothing, which is what made me think of it. So now I've shown my age and made quite the ass of myself, but what else is
So not the same thing. Sorry for the ruccus
You are right, I finally found this :
Handy PDF giving the 3 clock options for the 6500 series that commodore used. I can't however find a datasheet specifically for the transitional 6502 they used when going from the VIC-20 over to the first Commodore 64 which was the one I was thinking about.
However if the prior, and latter models used an external or on chip clock, I'd imagine so does the one I was thinking of.
I remember reading about a clockless MP they were putting into production and I can't remember the name of it. This is going to bother me.
Correct me if I'm wrong, I could be however if I am not mistaken, the early 6502 microprocessor used in Commodore 64 (and in later made VIC-20's) did not have a clock or need one.
;)
.. its now bothering me :D I know commodore made a small MP that did not have a clock core or use anything external. I'm just not sure if it was the 6502.
However I could be mistaken, and info related to the 6502 is a little hard to come by. Plenty of it from hobbyists however not all entirely accurate, and reaching CBM these days to ask is a little difficult
I think they're still in use in positioning devices that point things like satellite dishes and on microwave hops that auto correct their azimuth in really windy areas.
If someone has a commie gathering dust (or better the owner's manual) the exact specs and power consumption should be on the very back page. I wish I still had mine. If you have one, pls reply and let me know if I'm right

I think the whole point of the 'project' was to show that older hardware still had usefuless to some people, though useless to most. Mostly to (I think) try to convince people to get off their duffs, go out to the garage, grab those two old desktops and drop them off some place that could use them.
.. enjoy yourself some and tinker with your own :) Nothing wrong with taking some time to do something completely senseless if you enjoy it.
And don't forget Linux people tend to do things simply because they can. However I agree this is not great feat. This was plugging in a bunch of computers to a switch tossing in some CD's and powering up the boxes.
I once toyed around with some ULV p3 SBC's that I got in a lot. Nice low profile ones with a CF socket, all kinds of I/O risers and 2 on board nics. 5V at a pretty low draw, I was going to use some photovoltaic cells and some marine batteries to make a little eco cluster. CF is large enough (came with each one) to hold an etherboot setup / initrd and each one can handle 2 x 256 SODIMMs. May still do it if I can find a free weekend.. and the SODIMMs cheap enough.
If any applause is warranted, shoot over to the Parallel Knoppix site and drop the author a line.. he's doing some interesting things and is really enthused about his project. I host the only US mirror for k-pix, he could use some more.
Point being (and yep I have one) don't just post about how bad someone else's idea was
I was kind of intriuged by TFA so I did a little poking around on sites I knew off hand sold OEM naked boxes. However, I had a little trouble finding a place that would sell me something with no OS loaded, most are insisting you at least get something like DR-DOS (or slackware) just so they can ensure the thing boots - quite understandable.
.. and places I thought I may find people talking about their brand new inexpensive or custom boxes.
/. get bought out by Fox news?
/. - but nobody likes being mislead - and I'm guessing a few small PC shops lost a few sales. Nice going.
Then I fired up google groups and did a bunch of browsing around the hardware groups, and Linux groups
Every single one I found was pieced together in a custom config, or bought specifically for use as a Linux box. Over half I read (I sifted through about 20 posts) described going to several local stores to get everything in pieces to save money or get exactly what they wanted, or ordering components from a few different sites.
What this tells me is OEM's not offering MS products are not likely to lose market share as they compete in a different niche market, one MS doesn't seem to be able to touch.
So in conclusion I think this is from the 'if-you-can't-beat-em-try-to-null-their-market' dept , but is (at best) a feeble attempt from MS to do so.
What is rather disconcerting is the spin that was put on it, which could (possibly) help MS in their effort to take a bite out of that market as it does nothing but seed paranoia. Did
I know its
I looked for, but could not find any conclusive statistics that indicate if people who want a naked PC would be more likely to acquire parts and simply build it themselves.
.. but coming from a conspiracy nut (I'm one of the biggest) I'm inclined to agree and say ..
.. and a warning that they'll lose market share.
... I don't think so. And I'm no fan of Microsoft.
I'd like to see those statistics (if they exist) before I completely dismiss the validity of the article
bullshit.
It looks like this was aimed not at people who sell OEM (bare) as just an option, but people who don't offer Windows licensing at all
Gestapo-ish marketing, yes. Big brother
