Re: Microsoft *has* NOT won. AT ALL.
As a unix user/admin for multiple decades you are completely ignorant of reality. Really look around at the patent fights that are going on, anybody who believes Linux, etc have no infringing patents is just plain stupid. Seriously just look at the things others are getting sued over and now tell me that there is nothing in Linux that infringes. From stupid bounce-back patents to online shopping carts to how music is sorted... heck just last week bunch of podcasters were sued for infringing patents.
The belief that MS has no case is simply void of any actual critical thinking and is more a delusional fantasy... seriously put the smallest amount of mental effort behind it and think for a second.
Is this the 90's again?
Wasn't legalized fed wiretap ability the argument Clinton made about the clipper chip back then? Let it die already.
In 2007 Virgin TV had 3.6 million subscribers, since the numbers of decliens aren't known publicly. I have worked at a monthly subscription based ISP previously the number of declined charges we had were more than 1% of the subscriber base (I don't know the exact numbers but more than 1% and less than 10%), so with ~3.6 million subs no matter where you are in the range (1-10%) we are talking a rather large numbers of declines monthly (30-300k per month), which would be something rather costly to deal with by hand just to catch the odd unformatted text string .
Re: @Tom 35
Do you know why they have an exception in the first place? Over a decade ago, it came up and the reason given that they should be exempt from sales tax is that when it was enacted (Al Gore was still VP) the government ruled that because shopping on the Internet was very new, but they believed it had great potential and didn't want to hinder it's growth. So to give shopping on the Internet an explicit competitive edge to grow into actually something, they decided to not tax it until it got big enough to sustain itself. Is there any doubt anymore that shopping on the Internet is now able to stand on it's own two feet and no longer needs help from the government anymore? Why does shopping on the Internet need a government mandated cost advantage anymore? I think the Internet has grown up from the 90's and doesn't require getting a government advantage to compete with every other business anymore...
Re: Do your civic duty
Spread over only 144 total cameras all things being equal that averages to a income of $730.59 per day per camera.... holy shikey
Re: Yes but
Problem is that from a normal home power plug estimates a 2 day charge time, which means that you wouldn't be able to have a full charge daily.
The other big massive hole I see in this is that unless I keep my garage heated I will be losing money. Where gas powered vehicles, the power source just gets cold with the Tesla it goes poof into the air so it probably is dramatically worse for the environment as it consumed electricity from the grid, the cold whether took it away and you have to pay and use more resources from the grid to recharge a vehicle sitting still.
Not a windows guy and I didn't see any MS presentations on it, but the way one of the windows admins pitched it to me back in the day; was less on metadata stuff and more of a transaction based filesystem where you have equivalent of redo logs, etc than would allow you to roll a filesystem forward/backward in time and be able to replicate a filesystem by doing log shipping. As a storage guy that part seemed rather interesting to me.
Re: How fast?
Assume a fully pegged 10gig network interface usable capacity is ~2.8TB/hour (1000MB/sec * 3600sec * 80% usable). So to hit a rate of 16.3 TB/hr means it would need to support a sustained injest rate of 5.6x 10gig ethernet interfaces fully consumed.
If they can actually get anywhere near that for non perfectly designed benchmarketing workloads color me surprised... as I'm guessing that it's simply another storage vendor magical stat.
Re: Meanwhile KVM gets more developers
Better performance? That's very subjective and not what I've experienced. I would say that the general consensus on the net is that KVM trails ESX but true the gap that KVM is behind isn't as wide as it used to be.
Yup KVM doesn't have a license cost
Flexibility? Again depends, I'd say ESX has given me more much more flexibility then KVM does, sure you've got access to a more feature full hypervisor-ish layer where you can run apps on the host system rather than only in the guest, but does that functionality there mean the guests have more functionality... I've found it to be lacking. As your own post mentions even now the owners of KVM (Redhat) still don't have an officially supported method of taking online snapshots like vmware; now if you want to run production on a product that you can't call support on, and was released less than a month ago have at it.
Ummm... your example of upcoming KVM snapshots look surprisingly like vmware implementation. A separate file containing disk changes pointing back to the original... which is the same method vmware has been doing for years. By copying vmware's implementation KVM will have the same issues as vmware. So welcome to the party you are a few years late but you eventually did show up.
Even more so since he made that statement in Auguest 2007, just 2 months after the first iphone and a year before the first android phone. It really shows that Apple didn't start suing because all the phone guys were suing them first, like people like to claim.
What the two of you both failed to do is properly convert kb to mb. 56kb = .055mb (technically .0546875mb), you divide kb by 1024 to get to mb. That is unless you are a disk drive manufacturer doing bad math.
Ummm... what are you blathering on about?
There is a an official document from Microsoft on installing a Metro app outside of Microsoft's store.
Waiting for something that is actually grounded to reality and could possibly work. With this the requirement is a world wide grid requiring all countries in the world to sing Kumbaya in a drum circle,.as a country in the chain could throw everybody else awry. Countries would have to give up their ability to manage their energy policy and have one that everybody will just "play nice", most countries maintain their own oil, coal, etc repositories so when a country starts going crazy it won't throw their country into complete chaos.
That doesn't even go into the possibility of a global wide electrical brown out, which would be a distinct reality. What caused half of the entire US to lose power in 2003? A mistake by a single human forgetting to not restart a monitoring tool in a small powerstation in NY... That small powerstation malfunction caused a ripple affect throughout the entire US. Just recently think about what occurred in India a failure in a relay occurred that ended up taking the power out from over half a billion people.
Re: Copycat Microsoft
You do of course know that XBOX has been able to use Netflix, selling full tv/movies videos via their XBOX marketplace, streaming via DLNA and even usable as a media center extender for YEARS before Apple TV came out. If anything Apple has copied Microsoft as a media device.
The bottom line that TV is changing for Microsoft is that it sells XBOX units. I'm actually considering getting another XBOX to use with my bedroom TV, not because I want it to play games but because I can get to Comcast XFinity ondemand content since they have an app that Apple TV doesn't have, PS3 doesn't have, Roku doesn't have, Tivo doesn't have, but Microsoft XBOX does have. The Apple TV sucks compared to the XBOX for a multimedia device, it does everything it does and more.
And if anybody has vendor lock in it's Apple, dear god they threatened to pull their products out of an entire country if they had to license their DRM to third parties to allow itunes purchased content to play on something else.
If only that was true.... let's look at Apple's past history shall we on suing non-IT industries for daring to use an apple logo.
Apple sues a grocer:
Apple sues a school:
Apple sues a coffie shop:
Apple sues Woolworths:
Apple sues an APPLE FARM:
Re: He's not an alleged slave
Hmmm... prison in Belize or prison in US. US prisons may not be soothing architectural wonders like in Sweden but I'd venture a guess that a US prison is a bazillion times better than being the lone gringo in a 3rd world prison. If there was any chance of going to prison (even if the evidence looked worse in the US) I'd want the US legal system... maybe I've just watched Midnight Express one too many times.
Your name goes well with your job
Re: os/2 pricing to fail
I remember paying someone $100 for 1MB of used memory back at that time. The minimum requirements for OS/2 was a massive factor as to why I didn't run it even though I wanted to, I'm guessing that for a significant portion of the populace was as well.
The rationalization for me was this: I'm transitioning from the DOS world into the cool new GUI based world... I can either run MS Windows and have enough money to buy it and a number of apps, or have enough money to buy OS/2 and upgrade my hardware but have no apps.
Heck with ONTAP, fix the support organization
The horrid level of support is what turned us off of NetApp, they need to focus inward and get their support organization bulked up. First level are complete idiots, I've gotten people sending me a link to the same document that I opened the case with. Call back days later, incompetent support staff, it takes an act of god to get up to people who actually know something. After having them continuously in our datacenter for close to 10 years; we have since moved away from NetApp not because the competitors tech was really better but that the competition was good enough for our needs. Throw in that the sales & support organization blew them out of the water completely and making their technology value moot.
NetApp needs to focus inward, they need to fix their internal structures and reinvest dollars there, do that and the tech will win deals; continue down their current path and the competition's good enough NAS will win accounts.
Re: Apple users still win...
I'm pretty sure that is not allowed as part of Apple's app store terms, under the Trademark & trade dress section of their rules:
"Apps which appear confusingly similar to an existing Apple product or advertising theme will be
Apple won't let Firefox into the app store because iOS already has a browser providing similar functionality, if they allow Google maps into the app store they will be two-faced on that rule. I think they will cause a shit storm of complaints on randomly following their own rules and some big names might take them to court over it, either forcing Apple to accept apps they don't want (along with Google maps) or forcing them to reject apps they do want in the store.
Re: What's the point?
Instead of thinking of how it directly benefits the candidates, think of how it benefits the people they giving money to make ads. Something like getting a certain amount of $$ per view, and that being able to increase the ammount of people you sent the ad to equating to getting more money from a candidate. Wouldn't be out of the realm of possibility for someone to pay to signup a bunch of followers prior to an ad campaign inexpensively and then be able to charge more because of the increase number of "people" who were sent the ad.
your post is a perfect example of what's wrong
Your post is a shining example of why politics is broken. It's obvious from your post that you pretty much believe only people who are already behind a candidate would want to listen to what they say. Personally I believe in having an open mind and listening to what everybody says rather than closing myself off from them.
Re: Hashing is not encryption
He said *double* ROT13... so rot13 your text and then rot13 it again and just try and guess how that might relate to the original unencrypted data. Actually I believe he is a person who works in security, as double rot13 is kind of a "trick" of the trade these days.
Re: Today's shiny new Smart TV = Tomorrow's dated set you're already wanting to replace
I completely agree, unfortunately you hardly can find a mid to upper end TV that's not had the not-so "smart" additions. I just went through the exercise of replacing my 10 year old rear projection TV this year as it started to go it did 1080i fine until it kicked the bucket and I've got multiple external devices to do all the "smart" goodness (Tivo, Xbox, Blu-Ray, etc) so I didn't really want a smart TV. I ended up getting a "smart" one but don't use any of those features and still let my external devices do their thing.
From my experience is it seems TV manufacturers are separating their high end from their low end how much additional non-tv tasks it can do. The difference between the $500 and $800 model is the $800 can do Netflix (or you could buy the cheap TV and 3x AppleTV's), it costs them next to nothing to put that piece of software on add $1.00 for a ethernet and you've got a nice chunk of profit. You want a high end panel with good response time, etc that is purely a display only device I was unable to really find any in the $2-3k range, if you want to jump to the $5-6k on a TV they have a few that are non-polluted (but that's changing as well). Only the low end models any more are a "dumb" old traditional TV.
Re: Netapp has another ace
What??? Pretty much everybody in the storage industry is saying the exact opposite, NetApp doesn't have a flash/ssd solution and that EMC does. Just look on the blogs, NetApp has been talking how they don't need a flsh/ssd solution because their PAM cards are all that's needed... but are now changing that tune as they have a product. In fact EMC have an all SSD array already shipping that you can purchase. Rather than saying EMC needed it to compete with NetApp, the reality is more that EMC purchased it to keep NetApp from competing with them, delaying their entry into the market EMC is already in and shipping a product for. You gotta have deep, deep pockets but the fact is they have a product and NetApp doesn't.
The way WAFL works is that it always does full raid writes to avoid a penalty of having to read in existing data from disk. The entire point of WAFL is to avoid the partial raid write latency impact of rotating rust, using flash storage removes the rotating disk latency impact so the value of WAFL on flash becomes pretty much null. If you have enough cache in the array any array can do full raid writes just like NetApp (that cache might have to be infinitely large though), WAFL just allows it to write "anywhere" in an aggregate so blocks generally are not sequentially close to each other. If you go to an advanced NetApp performance class the instructor (at least ours did) will directly say that NetApp's are designed for high write performance not read performance because of this. I've found from our NetApp's that reads are generally the speed of a drive seek, for random read workload doesn't impact much, but if your workload has any sequential work load you can drive seek yourself into very slow performance.
Re: Isilon slow?
The Isilon has two series: the X series geared towards sequential video streams (like NetApp's LSI arrays) and the S series geared towards random I/O.
From the specfs benchmark which does test a good chunk of random workload: the Isilon S200 series hits 1.6 million and the largest 24x node NetApp 8.1 cluster hits 1.5 million. So I'd say that fully popped either platform can do an "oh my god" level of random I/O for an "oh my god" price point.
Why would they capture the data? Because SSID's are generally unique to an area, add in more than one and you have a fairly specific physical location reference. GPS doesn't work everywhere (outside around tall buildings, inside buildings, etc), but using the not that acurate cell tower triangulation with wifi SSID's and you can get a fairly specific physical location reference without any GPS signal at all.
I have a Motorolla Razr Maxx and it has an option to due certain things based upon location (i.e. at work change cell phone ring to vibrate, at home audible ring, etc). It uses wifi ssid to identify when you are at each location.
Apple uses (or possibly used now and built their own database) Skyhook for non GPS location via wifi and cell tower mapping.
Re: Thanks GOP
Why do you think I'm a member of the GOP? Oh I get it in your world anybody who is against something is automatically a member of the GOP... a closed minded political bigot. Good to know.
I find it very interesting you intentionally forget to mention that it was unanimously passed in the House, and unanimously passed in the Senate and signed into law by Clinton... but it was only one party who is responsible. It's not like the current VP of the US was invited to a special event by the RIAA/MPAA to honor his and 3x other members of the legislature on getting it through or anything. Oh sure it's just the GOP, not like everybody or anything; oh to be able to live in your black and white world....
On net neutrality have you read the law (also do you know it was sponsored by both GOP & DEM)? I have a similar problems with it... it doesn't do what most people think it does. It only protects lawful data (paragraph 64), so if you are downloading some content not available in your country via an in country proxy net neutrality doesn't protect you at all. Additionally there is no real prevention of degrading service, they can't degrade your torrent download/ netflix stream to where it's unusable but they can make it run at less than a MB legally (paragraph 66). ISP's are still allowed to degrade the service of people who use more than others (paragraph 73), don't get me started on how bizarre they are applying rules to mobile internet. Again like the idea, like most of it, but there are some real problems in the FCC rules.
We should *always* be worried about badly worded bills from both parties, I still don't understand why you seem think that a poorly written bill is just "peachy keen".
As I'm a registered independent who has an open mind and willing to call both parties out, I'm not getting into your whole GOP is evil and Dem are just fine (emphasized by your intentional lack of any complaints about them). But I will disagree in your supposition in that this amendment was good, it was bad, very bad period.
Re: Thanks GOP
Maybe if the writers would actually write a good bill people would vote for it.
I'd vote for an amendment saying that "individuals can not be required or coerced to disclose personal account or password information to current or prospective employers".
I would not for vote an amendment saying that "Congress will give FCC the power to regulate privacy on the internet which also includes the ability to make rules about mandating disclosure of passwords by job applicants ".
If you can't understand the difference between the two than you are simply an idiot. Write a good law to begin with and people from either party will vote for it, write a poorly drafted one even if it has good intentions behind it and (smart) people will not vote for it. What part of that is hard to understand for you?
Really, do you want another poorly written DMCA type law on the books? Because that's what this amendment is another crappy reaction that has basically good intentions but written horribly, how hard would it be to re-write that paragraph to contain what I wrote vs the broad sweeping crat that was actually in the amendment... but I guess you are all for DMCA type laws based on emotion rather than intelligence. Me, I prefer to have a well written law that explicitly says employers can't look at my stuff rather than saying if the FCC decides to in the future do something they can but they don't have to.
Re: Thanks GOP
I'd suggest you read the amendment first (it's literally a paragraph long)... it was way over reaching and removed much of the power from the legislature and gave it to the FCC... as such it *should* have been dumped like the DMCA, not a completely horrible idea but a completely horribly written law.
It was giving the FCC additional power to create rules over *all* privacy matters, not just job seeking social network passwords. It didn't even say that the FCC had to prevent it, it was all about giving the FCC direct power to make rules about online privacy without the need of any congressional oversight and if the future they were to make a rule it could possibly include one about social media passwords and the legislature couldn't do anything about it no matter how bad or good it is. Having seen how messed up the FCC is about showing a nipple on TV, I'm not ready to give them that power; not sure why any sane person would want to give them that power either. Granting power to groups of the government (especially one that isn't voted in by the people) needs to be *explicitly* stated instead of wide sweeping grant of power to regulate all of something. With this amendment, the FCC could make a requirement that everything needs to go through a "great wall of US" firewall to protect the privacy of US citizens from other countries, extreme example yes, but this amendment would allow them to do that completely legally and there really would be no person to vote out of (or into) office about it.

No entrapment defense here
In the US, entrapment means that law enforcement coerces a person to do something illegal that they normally wouldn't do. Additionally if the government induces (persuades or mild coercion) a person to commit a crime, if the prosecution can show they have a verifiable predisposition to crime already entrapment defense wouldn't hold up either.
A person is 'entrapped' when he is induced or persuaded by law enforcement officers or their agents to commit a crime that he had no previous intent to commit; and the law as a matter of policy forbids conviction in such a case.
However, there is no entrapment where a person is ready and willing to break the law and the Government agents merely provide what appears to be a favorable opportunity for the person to commit the crime. For example, it is not entrapment for a Government agent to pretend to be someone else and to offer, either directly or through an informer or other decoy, to engage in an unlawful transaction with the person. So, a person would not be a victim of entrapment if the person was ready, willing and able to commit the crime charged in the indictment whenever opportunity was afforded, and that Government officers or their agents did no more than offer an opportunity.
Even if inducement has been shown, a finding of predisposition is fatal to an entrapment defense. The predisposition inquiry focuses upon whether the defendant "was an unwary innocent or, instead, an unwary criminal who readily availed himself of the opportunity to perpetrate the crime.
No it doesn't say:
"it could be losing as much as 24 billion tons OR as little as zero".
It says that "it could be losing as much as 24 billion tons or GAINING as much as 16 billion. For some reason you decided to forget about half of the the plus or minus part.
If you are going to go around correcting people, if you don't want to look like a complete ass your complaint should really be correct... or maybe your agenda is showing.
Hmmm... would you care to provide some facts to backup your data?
Please feel free to backup your statement with some actual documentation that it is *not* illegal. What I've found is that there is quite a bit of murkiness as to it's legality but you have made a very definitive statement that it is not illegal. There is no question in your statement, so please provide some evidence that is as conclusive as you make it to be.
From what I know, there was a previous situation in the UK with the website tv-links which would seem to imply that it's not that legal in the UK.
The site, TV Links (www.tv-links.co.uk), was providing links to illegal film content that has been camcorded from within a cinema and then uploaded to the Internet. The site additionally provided links to TV shows that were also being illegally distributed.
takes a lot less than 30% for music???
"Currently iTunes charges 99-cents a song, with 61-cents of that going to the record industry, 9-cents of it going to the artists and the rest going to Apple."
$0.29 / $.99 = 29.29% is what iTunes take or basically 30% of the take per song.
Will it be different for Apples cloud offering and be as you say "a lot less than 30%"? Well lets take a look shall we?
"Apple has agreed to pay each music label between $25 million to $50 million for their services. The music labels will then share the cost with Apple; 30% will go to Apple, 12% will go to the music publishers, and the remaining will be left to the labels to pay out their artists"
Feel free to bring some factual data along with your posts...
US has one of the highest Corp tax rates in the world
President Obama in his State of the Union speech this very year says the US has one of the *highest* corporate tax rates in the world, and politifact did a verification check and validated that the US does have one of the highest corporate tax rates in the world. Would you care to bring some facts to the table?
"Over the years," he said, "a parade of lobbyists has rigged the tax code to benefit particular companies and industries. Those with accountants or lawyers to work the system can end up paying no taxes at all. But all the rest are hit with one of the highest corporate tax rates in the world. It makes no sense, and it has to change."
We found that for 2010, the U.S ranked second to Japan by a fraction of a percentage point -- 39.54 percent for Japan to 39.21 percent for the U.S. But that figure is already outdated: Japan has moved to cut its rate for 2011 by 5 percentage points, leaving the U.S. with the highest corporate tax rate among OECD nations.
No you aren't going to look like a complete twunt
That is unless you go running around making a big scare about it to management, and then later have to look like an idiot.
You said each of your hypervisors have 48GB of RAM in them so having to buy more licenses would make you look bad, however having more license capacity probably wouldn't make you look bad.
An ESX server has a minimum requirement of 2x CPU's (it's base requirement), so taking the absolute worst case situation and you have a two socket CPU configuration you are covered. With the Enterprise license you have 32GB of vram per CPU, since you already have to have 2x CPU's per server by basic requirement you are already have a minimum of 2x Enterprise CPU licenses which give 64GB of RAM per server which is more RAM than you have stated you have in your hypervisor (48GB). In fact you could have just the essential edition and still be covered (24GB/CPU * 2x CPU = 48GB)
EMC & Flash on the host
I think it's much simpler than I've seen people speculate so far. I think it will be as simple as enabling the functionality via a key in their powerpath product. Powerpath already can be used to move data from lun to lun on a host, it seems like it would be extremely easy to extend that to local SSD.
If they use that methodology, I'd guess that the write to SSD & array is very low risk as it's more of the same: a write comes in gets intercepted by powerpath and it writes to both the array and the local SSD (just like doing a powerpath lun migration so nothing really new here). No real risk of dataloss as they've been doing split writes via powerpath for a while. There would have to be some new bitmap matching intelligence but I can't see it be that difficult. Throw out the oldest accessed block on the SSD and write new data to there update bitmap. A read would simply look at the bitmap: is the block in the map? If not request data from array.
Doesn't seem like it'd take much time to get something like that going, of course that's my speculation... and EMC might be doing something completely different; but it sure feels like that would be a very simple, low-risk option that could be into customers without years of work. Be a very easy sell as well, you've already got powerpath installed on your system... all you need is a a license key and you can be offloading array reads to local drives, no reboots, no recertification, no drivers it's already there.
I'd like to live in his alternate reality...
As a Linux user for not quite 20 years (but getting there), he seems detached from reality. Linux people need to accept the reality that there is large quantities of patented items in Linux. All one has to do is use the slightest bit of critical thinking to realize that:
Microsoft spends millions of dollars and man hours just on ways to avoid them from violating a patent and yet they constantly are. Why would open sourcepeople believe they match or even boast they don't have any and it's all "fud" the same level of violations as MS; when they have no where near the resources looking through their data (which if we are talking opensource as a whole has an order of magnitude larger codebase)? When someone says that it's FUD when MS says Linux is violating a patent, I roll my eyes and think they are simply blind morons. If companies with hundreds of people being paid just to make sure they don't violate patents aren't able to keep their noses clean what level of stupid do you have to be to think that joe schmoe contributing code would be able to?
Problem isn't speed... it's quality of patents
The problem isn't that the US is generating patents too slowly, it's that the patents they are awarding are too broad and of poor quality. I can only assume that since Obama's intent is to make the system work faster, the accepted patents will be poorer and poorer as speed is the enemy of quality.
Awesome, I love this
I'm so very happy that EMC has done this... maybe it will hasten the demise of all these stupid storage benchmarks. SPEC, SPC, etc all are completely useless and meant only for vendors to see you something. Now all the other vendors will go play the same stupid game to have the top numbers. Making these already useless benchmarks more obviously useless to the masses.
Hopefully all customers will then start throwing it back at the vendors like I've been doing for years now calling them on how it's complete and total BS (you won't believe the argument I got into with a Sun/Oracle sales guy). The only valid benchmark is one done to simulate my workload. If the vendor can't benchmark my load, then sell me a solution with a SLA to support a stated IO workload; if they are confident in the solution they will stand behind it (I haven't had a vendor walk away from a deal yet requiring a SLA with a stated IO workload).
I believe he's meaning in aggregate broadcast
With broadcast there is no bandwidth increase based on the number of customers. i.e. 1,000 customers have the same bandwidth requirement a 100,000 to watch a single show at the same time (US HDTV spec has a peak of ~19mb/sec which you never get but that's the spec), ignoring requirements for repeaters, etc you have a constant peak requirement of 19mb/sec. With Netflix, etc (anything that isn't using multicast to send the data) everybody gets their own point in time, you aren't tapping into a constant feed. Minimum bandwidth for a HD Netflix show is around 6mb (it can go higher, lower generally is SD).
So 1000 users watching the same HD show simultaneously
Broadcast = 19mb/sec peak
Netflix = 6,000mb/sec minimum
To put it another way: Comcast has 16.3 million cable customers, if 50% of them are watching something at the same time. It would require 48,900,000 mb/sec or ~46.6 terabit of bandwidth.
Assuming the same 50% of the Comcast customers are watching something, and lets say they are even spread across 200 different shows simultaneously at the peak load of 19.6mb per show that would require at max 798,700mb or ~0.76 terabit of bandwidth.
789700mb / 48900000mb == 1.633% == the percentage 19mb broadcast bandwidth stream requires compared to a 6mb non-broadcast stream for the same number of customers.
I'd say that the current method of "on demand" HD streaming isn't sustainable right now for everybody (maybe in a few years that will change but it won't be cheap), but if there is a switch to multicast or equivalent it could be.
Oracle on the T* boxes
We've had nothing but problems with running Oracle on our T* boxes. The M* series is much, much more suited for it and find the performance of the T* boxes inadequate for what we need it to do. Fewer CPU's with more ooomph per core is much better than lots of slower threads for 99% of all the database instances we have (both OLTP and data warehouse ).
If you do a search on the web our experience with T series and Oracle seems to be the norm rather the oddity. (there's a reason licensing is so cheap for Oracle on the threads... it generally sucks)
Allways have that argument without merit
As a person who's been around some version of unix (workstation to server) for over 2x decades, the argument that unix workstations are safer because people *have* to escalate their privileges for a number of tasks is without merit. (Note the word workstation)
If I download some app off the web that wipes all of my personal photos, do I really care that much that /bin/sh was not able to be modified? Do I care if the browser has a malware addon giving out my bank information to someone else that only gives out information for when I login but not when the the root user does. If my doctoral thesis I've been working on for the past 5 years gets blown away, I really care about it and having to type a password to become root doesn't protect me.
I find the often used argument that a user on a workstation can operate a lower level "protects us" completely devoid of reality. It sounds blasphemous but I don't really care about protecting my workstation OS, that's the last thing I really care about, it's pretty much a throwaway (I have no love for the version of /bin/bash and require keeping it); but I do care a whole hell of a lot about protecting all the things I've done with the OS: i.e. not having files deleted, not having personal files copied, not having my browser leak information, etc. Running as a non-privileged user will not protect you against that. The ability to break into root on a workstation might get headlines but for the most part who cares if all your user data is gone?
Savings of .1% not so neglible at scale
From Dell's quarterly statement... that had 12.431 billion in expenses in the last quarter. Let's assume 10% of the costs are going to these people (since Dell for the most part just does final assembly of other people parts: rather than actually make chips, motherboards, etc this percentage should be higher). 10% of 12.4 billion is 1.24 billion, .001 of 1.24 billion is 1.24 million/quarter.
Not sure about you, but 3.72 million in yearly income by just delaying payment a few days isn't neglible... as long as you don't piss off your supliers so much it cause a mfg chain problem seems like a really easy way for a huge organization to pad the bottom line with limited risk organization and hardly any cost at all (if it causes problems for critical suppliers, you can just start paying them sooner... no real capex/opex investment required for the change).
Comcast are pretty much static
Ummm... until they did some network changes here, I've had the exact same comcast ip for over a year. That was during power outages, etc. where the routers and cable modem were rebooted. I've also had a port nailed open for multiple days (actually more like multiple weeks) so they don't kick connections either. They definetly don't flip ip's or drop every 24h, not sure where you got that information from. Sure they assign me a dynamic ip address, but if that dynamic address doesn't change for over a year (through reboots, etc) you can hardly say that ip tracking isn't useful. Additionally even modem banks which have a high-rate of change per customer haae a small finite range of ip's it will use. Using that finite range combined with other data (time of day, etc) u can identify an individual fairly easily as well.
Don't compete against each other..
That is the most telling statement to me, it shows that MySQL under Oracle would never be allowed to compete with their Oracle DB. While MySQL isn't a feature competitor against Oracle today, people have been working on it, Oracle is basically broadcasting that MySQL under them would not be allowed to grow into a feature-full DB and keep them in a "different" market.
Why is it easier? I can more a running VM from one physical server to another live with no downtime. Ever try to coordinate a downtime with a database or exchange for thousands of users?
True doesn't help much with app upgrades, but the wonderful thing is that I can take a snapshot and rollback immediately if the upgrade goes bad, etc.
Being hardware independant means I can take the virtual machine running on an old Dell with different scsi cards, etc and move it to a new HP within seconds. I don't have to install an OS, I don't have to re-install the app (and hopefully remember all of the manually changed settings done over the past 5 years), it's completely self contained and I can complete it quicker... i.e. less downtime to the business which means less $$
Why run them on the same system? Because as you scale up the number of services in your environment, isolating them is a good thing for your sanity. Security is the obvious first thing, it's much easier to protect a webserver if that's all it does, it's much easier to protect a mail server if that's all it does. Additionally think about patches you want to patch the mailserver from the latest exploit, but it changes some files that the webserver uses... do you want to pull your QA group away from whatever they are working on to do a regression test across your webserver? How about organizations where there isn't the lone admin, where different people do different things (Oracle DBA's don't go on our webservers). I can now only take downtime for a single service rather than lots of multiple services (I allude to this above, try and coordinate simultaneous downtime for your web, mail, dns, firewall, etc at the same time to patch the OS have fun with that). The penalty is measured in single digit percentages relative to peak. So unless you are running your system 99% utilized to begin with you will see hardly any slow down.
Hmmm... net neutrality for others maybe?
So comparing the two
"Google asserts that blocking calls to certain numbers is necessary as such calls were eating up 26 per cent of Google Voice's US running costs."
"Comcast’s plan is to identify the 2% or 3% of customers who over the last hour or two have consumed more than 50% of the capacity on the network, Werner said. Those heavy users are then given lower priority and will have their bandwidth limited for a temporary period of time."
I have to wonder why Google doesn't get the same bad rep as Comcast when their cutoff level is lower than Comcast?? I'm thinking Google didn't quite think things through on what they were requesting on the whole net neutrality thing there...
*NOT* just for the checkbox
If it's an ATA drive it's absolutely required these days, period end of story. I told both 3PAR & IBM (XIV product) to not talk to me about using ATA storage until you have that. It's not about how fast you do a rebuild, it's about how big of a rebuild you have to do. It's all about URE, I've got literally thousands of drives on the floor in the datacenter, you don't have 2x drives stop spinning, which is really where you care about how fast a rebuild is. A URE stands for "uncorrectable read error", which means that the drive thinks everything is fine and you make a request and it is unable to fulfil it. There is nothing the drive array can do about it, it's part of the drive. Goto Seagate, Hitachi, etc and look it up, most standard ATA drives have a drive manufacture failure rate of 10^14 (or ~12TB). So let's say I's using big raid5 groups 6+1 using 2TB drives (12TB usable). Statistically during a rebuild you are more likely to not to have some data loss. It might be a single 512byte bit, but that 512byte bit could include an oracle datafile, a critical bank transfer, or whitespace that you don't care about. Constant disk scrubbing minimizes this as it should find those failing sectors before the entire drive failure
I've personally had a raid5 drive failure + URE event in a raid event, only a single sector couldn't be rebuilt but it wrecked havoc and ultimately made ~30TB of other VTL data useless (the VTL app spread the writes around the array... very similar to 3PAR). So I'm not talking out my ass, not am I looking for simply a checkbox (note this was on 320GB pata drives so it was a few years ago).
I suggest you do some reading up, as it's a very real danger.
