Comment Re:What about VCE and VMWare? (Score 1) 97

I honestly haven't looked at Dell hardware for a very long time, since most of the physical stuff we deploy is outside of the US and they have horrible international warranty service. Their low end consumer PCs are garbage and always have been, but I've heard the business lines of desktops, laptops and servers are still halfway decent.

Warning: anecdote from a Winddows admin incoming.
I started working in a Compaq shop. Which became HP, of course.
Then a heterogeneous shop with IBM, Dell and HP.
Then an all-Dell shop.
Then an all-HP shop.
In my experience, all three brands have had generally the same reliability and performance - but the ease of server management (installing drivers and updates, configuring lights-out management and alerts, etc.) and the experience of tech support have been significantly better with Dell.

(Regarding SANs - I've found that EMC is ridiculously fast yet ridiculously cryptic to manage, EQL is ridiculously easy to manage yet struggles on performance and reliability, and new tech like Nimble so far appears to be both very fast and very easy. It'll be very interesting to see what an EMC/Dell merger would produce. I have zero experience with Compellent.)

Comment Re:Do they count rollbacks? (Score 1) 246

I'm curious if you looked at Windows Update -> Advanced options -> Choose how updates are delivered. I ask because when enabled there are a couple options to download updates either from other machines on your local network, or any machine on the Internet. It sounds like Microsoft is leveraging some peer-to-peer networking for content delivery, and I wonder if that's what you're seeing. It would explain why the destinations kept changing, as other PCs came and went... One implication, if so, is you could possibly have disabled that and gotten updates directly from Microsoft only.

Comment Blacklists (Score 1) 106

There are plenty of such blacklists already published.

You can compare your list to others to see if you have anything unique, and if you do I guess your options are either publishing your list on your own, or seeing if any of the other list would like to merge in your list. Some of the lists allow sites to remove themselves. Some of the lists appear to only have "recently" spamming addresses. Some lists specifically exclude residential ISP connections. There are probably other methods of addressing your ethical issue too.

An ars article seems to give the clearest view of a rather murky subject. Basically, there appears to have been multiple ways in to the data. Including situations like IT contractors hiring database admins located in places like Argentina and China, at which point it doesn't matter what technical security solutions are put in place since people are explicitly given full access to the data. (I guess technically that falls under the "inside job" scenario?)

Comment Re:The Microsoft key!!!! I've never used it...ever (Score 1) 698

Windows overloaded the alternate key for opening menus, which meant that it is no longer a convenient key if you need to enter non-ASCII characters (for example, a Euro symbol or a letter with an accent, which are both easy to enter on a Mac).

I don't know how it works on a Mac, but entering alternate characters is still easy with Windows, even 8.1. (I haven't tried it on 10.) Rather, I consider it pretty easy. :-) Just hold down the ALT key, type in the four-digit code for the character you want, then release the ALT key and your character will show up. A Euro sign is ALT+0128, for example. â. (That would show up as proper Euro, except this is slashdot. -roll eyes-) Doesn't matter if numlock is on or off, doesn't matter what you might be doing with a menu at the time.

Comment How is it like the 80s? (Score 1) 287

An article at TechCrunch looks at some interesting parallels between the current automobile industry and the PC industry of the 1980s. IBM was dominant in 1985, employing four times as many people as its nearest competitor. But as soon as Windows was released, the platform became more important for most end users than the manufacturer.

What an odd claim... The article describes the 80s PC industry as one dominated by a single company, IBM, with over four times as many employees than the second largest PC company. So which automobile company has more than four times as many employees as the second largest? I can't find employment info, but in terms on unit sales, the top three are at 10 million, 9 million and 9 million. Hardly an industry dominated by a single player - it's the 12th ranked manufacturer that the top one is four times the size of (in terms of unit sales, again.) So whatever state the car industry is in, and whatever happens in the future due to in-car entertainment systems, I don't see how it at all resembles the 80s PC industry.

Whatever the computing power (CPU, RAM...) is now, you can expect it to be greater in the future.

Whatever the price is now, you can expect to be less in the future. Ten bucks each (just an illustrative number, I really have no idea) right now because they're made by hand? Could be in 10 or 20 years you'll get 10k units for your ten bucks as they roll off a mass-assembly line.

Moore's Law and all.

Don't think of this as a consumer oriented coin-sized desktop with a popular brand's logon on it that you can carry around in your pocket. Think of this as something you purchase in 40 kg batches, fitted with the sensors you need (light, sound, vibration, chemical, pressure...) that you then scatter about. (Assuming they have wireless connectivity, yes. They'd be useless if you have to run wires to each one to establish communications.) You would simply not care if one is lost forever - you'll just buy another 40 kg batch when these wear out, are damaged, or scattered too widely by the wind. Military, environmental and health monitoring possibilities were mentioned in the article. Vernor Vinge's science fiction novels are the first time I recall encountering the topic, back in the 90s.

In Denver, CO we can choose between Century Link DSL (speeds suck) or Comcast (expensive and service sucks). If the city of Denver jumped in that would at least give us three choices. Competition is good, right?

I've seen ads from Century Link that they plan on offering 1gbs fibre service in Denver. I haven't looked into it, so have no other information (timing, area, cost, etc.) In the meantime, your neighbors to the north in Longmont approved municipal gig a while ago and signup for the service in the first area has begun. Apparently a dark fiber loop was laid a decade or two ago while other work was being done, but state laws - the usual we've heard about here on slashdot - prevented the city from using it to offer service. State law changed, the city voted to utilized the fibre, then again voted to fund it with bonds for a phased but quick rollout over three years instead of using subscriber proceeds for a rollout over decades. The fiber is getting expanded to all parts of the city, absolutely anybody who wants it will be able to get it, from what I understand.

Comment Re:But is it even usable? (Score 1) 208

I don't think you can make valid estimations about the write speed of this new potential format by assuming it'll work at LTO 6 speeds. As density goes up, so does write speed.

Consider LTO 1 through 6:

  • LTO1 - 4880 bits/mm, 20 MB/sec
  • LTO2 - 7398 bits/mm, 40 MB/sec
  • LTO3 - 9638 bits/mm, 80 MB/sec
  • LTO4 - 13250 bits/mm, 120 MB/sec
  • LTO5 - 15142 bits/mm, 140 MB/sec
  • LTO6 - 15143 bits/mm, 160 MB/sec

It seems that doubling storage density yields slightly more than double the speed. (And obviously, like going from LTO5 to LTO6, speed can be increased without any sort of density improvement.) So if we extrapolate that to this new format, at 74 times the density, it perhaps can perform at 74 times the speed, and therefore fill up a tape within a reasonable timeframe. (Which, admittedly, is pure speculation - until actual speed specifications are released for this format, we just don't know.)

But if I was an IT manager, I wouldn't be looking at 185 TB tapes in order to do a full 185 TB local backup every weekend to be sent to an offsite vault. Instead, I'd be looking at 185 TB tapes if I had a remote site, at least 20 miles away, I'm connected to via a fast fiber link, that holds an active replication of my entire 50TB SAN, and I want to store a year's worth of weekly backups, plus a few month's worth of daily backups, in a 40-slot tape library instead of multiple 200-slot tape libraries. Then I could quickly restore almost any file without having to recall tapes, plus have a hot and ready copy of my data in case a flood, fire, earthquake, etc., strikes the primary site. (The logistics of setting up the network, the servers, the SAS connections, etc., not withstanding. :-)

Such a tape isn't for home use or small business use - it's for IBM, Google, Amazon and the like I suspect.

Interpreting your own numbers: Q1 2013 22.9 Q2 2013 19.5 That is a drop of 14.8% Q1 2014 26 Q2 2014 16.35 That is a drop of 37.1% The rate has down more than double from Q1 to Q2 between 2013 and 2014.

Comparing two different quarters doesn't tell you much - items like this sell at very different rates in different times of the year. You get much better insight comparing Q1s to other Q1s, etc. Which in the iPad's case is down, yes, but it's directly after the iPad's best quarter ever, and is a year after Apple had a particularly good quarter for iPads due to fulfilling a backlog (according to another post in this thread.)

So in my estimation - too early to claim "cooling," and definitely nowhere near "freezing."

Comment "Officially," eh? (Score 5, Insightful) 386

Hmm. iPad sales:

Q2 2014 - 16.35 million.
Q2 2013 - 19.5 million.
Yes, that's a drop in sales.
But, it's after the following:
Q1 2014 (includes holiday shopping) - 26.0 million.
That's the all-time high sales volume for iPads in a quarter. 2nd best is Q1 2013 at 22.9, significantly less.

In my mind, the way to interpret these recent iPad sales numbers is that there was a huge buying spree for the holidays that somewhat satiated demand. (Only somewhat - Q2 2014 is still the 4th best quarter for sales.) These numbers don't suggest to me that the "fever is officially cooling." Maybe it is, but more than just one quarter of numbers is needed to show that.
