That sounds great and all, but it sill makes no difference when the major ISPs won't pay for enough upstream bandwidth to support their customers. I'd like to see the FCC enforce a consumer SLA that guarantees USABLE bandwidth.
You can't legislate good customer service. Besides, the inventory overhead would be unreasonable.
But, this is T-Mobile he's talking about. They use SIM cards. The store could just program a SIM card, slip it in a random unit someone traded in last month, and let him walk out of the store at least being able to make phone calls. Heck, they might not even care about getting the loaner unit back, depending on its resale value. It's the sort of courtesy that encourages repeat patronage.
I disagree with this faith in SMART to provide aqueduct warning. So does Google.
Out of all failed drives, over 56% of them have no count in any of the four strong SMART signals, namely scan errors, reallocation count, offline reallocation, and probational count.
We conclude that it is unlikely that SMART data alone can be effectively used to build models that predict failures of individual drives.
Google's analysis was of spinning hard disks, but I can not believe that SMART is somehow better at monitoring SSDs than spinning hard disks. I have personally had drives that pass every smart test and hard drive scan, but click and buzz in unnatural ways. Likewise, I have had SSDs suddenly fail that were, by all external tests before and after the failure, operating within expected parameters. It doesn't help that many SSDs have a habit of rendering the stored data inaccessible with no chance of recovery when they loose power. Spinning HD manufacturers solved that problem decades ago with self-parking read-write heads. Then again, there is no SMART test that's going to predict when an electrical component is going to suddenly burst into flames. (I've seen it happen!) With a spinning HD I could replace the logic board or send the disk out for recovery and get that data back, probably unscathed. With an SSD the odds would be in no-one's favor.
When it comes to SSDs, the PC vendors need to step up their game on data redundancy. SSD Raid 1 arrays or integrated backup to cheaper storage should be standard configurations.
"Self defense"? Look, you can call it a lot of things, but you can't call it that. Otherwise I could call the following scenario "self defense":
Guy comes to my house and kills a member of my family. In "self defense", the next day I go and burn down his house with him and his family in it.
Is that seriously your characterization of the war in the Pacific in WWII? Japan bombed Pearl Harbor then the US dropped nukes on Hiroshima and Nagasaki? There was a lot more to it than that.
Let me repeat. The beams that create the channel are not themselves channeled. So the channel itself... has the diffraction, scattering, and beam spread of an unchanneled beam. The net result can't be better than an unchanneled beam, because it is made out of an unchanneled beam.
Not necessarily. Since the surrounding laser pulses should spread in a more or less uniform way, the central channel of denser air should still occur as distance from the emitter increases and remain centralized in the channel. It sounds like it will make air work a little like graded index multimode fiber. The difference in density between the central channel and the surrounding air will likely fall off with distance, making the air channel less efficient, but still present out to some distance. It's not like this would allow perfect single-mode propagation to infinity in a coherent beam, but it could improve bandwidth and/or distance capability for point-to-point laser communications.
Server 2012 R2 has and improved interface for remote manageability. The start button is there for pulling up the Metro screen and the metro screen has clickable icons for logging out and restarting or shutting down. From the Metro screen I just type the name of whatever program or configuration utility I need, and that works as well as the windows 7 start menu. The interface has improved to be merely annoying and cumbersome rather than obstructive and rage-inducing.
Except, according to Verizon's own published chart those links are at 48% peak utilization. It seems is some headroom there. http://publicpolicy.verizon.co....
Up above, you posted that the problem is that Level 3 charges, "300% higher than any other provider out there..." http://slashdot.org/comments.p...
Which means: You are talking out of both sides of your mouth.
Exactly right, and that's because local caches and peering to content providers saves money. Buying capacity and data transfer from a tier-1 is expensive. Peering with content providers is cheap.
Nah, it's worse than that. Wall-mart will let you shop wherever you want, but Target and Costco have to pay up if they want the exit ramps to stay open.
No QoS - ISPs will have to drastically upgrade bandwidth capacity so that VOIP and video traffic don't get choked out, and Cisco sells more equipment.
Yes QoS - ISPs will need to drastically upgrade network processing capacity so that VOIP and video traffic don't get choked out, and Cisco sells more equipment.
I'd wager that the problem lies in Time Warner's links to the tier 1 backbones, and not traffic shaping. If those links are saturated, as Level 3 and Cogent have complained about, then any traffic routed through those tier 1's will suffer. But the Time Warner hosted speed test will work perfectly. Technically, Time Warner is right, they are meeting requirements for the link form the customer's home to Time Warner. It's too bad they don't make any promises about usability.
Have you trace routed to popular sites or tried an independent speed test?
About 8 years ago I was going to Europe, so the day before I leave I call up my credit card company to let them know to expect to see a lot of charges from abroad. The account rep tells me that I would not be able to use my card because they had just sent me a new card and the old card had been deactivated. I was to expect the new card to arrive in 3 or 4 days. "Well great," I sez, "but I'm going to be in Europe, so I won't have the new card. Why did you deactivate the old card and send me a new one?" The Answer: they were just replacing people's cards for the hell of it. Credit card companies suck.
Collateral damage. Both Cogent and Level-3 have accused Comcast of degrading service to coerce content providers, CDNs and backbone providers into giving them more money.
Comcast is peering with Cogent, and that is the connection that is saturated. This is why people can VPN around the problem, as there are many routes into Cogent's and Comcast's networks and anyone with a rudimentary knowledge of internet routing understands that routes change depending on source.
But Comcast is not Cogent's peer. They are Cogent's customer. Cogent sells bandwidth and data to ISPs like Comcast. Cogent has no reason to peer with Comcast, an ISP, the way they do with other backbone providers. Cogent is no longer happy with this arrangement and is trying to change it.
The reason VPN works is that Comcast was deliberately degrading Netflix's data stream and VPN conceals the nature of the traffic. Comcast's excuse doesn't pass the sniff test - much like any bullshit.
Yeah, they probably are using UDP in some video tests, but I think that is irrelevant. If this is a competing technology to Reed-Solomon encoding, then it is almost certainly a data-link layer protocol and is agnostic to network or session protocols.
From Wikipedia:
Reed–Solomon codes have since found important applications from deep-space communication to consumer electronics. They are prominently used in consumer electronics such as CDs, DVDs, Blu-ray Discs, in data transmission technologies such as DSL and WiMAX, in broadcast systems such as DVB and ATSC, and in computer applications such as RAID 6 systems.
I think the writer's mistake was in seeing everything through Internet-colored glasses. The article specifically says "link layer", not "session layer". TCP is a session layer technology. My best guess from the article is that this is not an end-to-end error correction protocol to reduce IP packet retransmission. It is an error correction protocol to reduce OSI layer 2 packet (or more properly, "frame") retransmission.
I think the writer is confused. This sounds like a non-routed layer 2 error-correction protocol for error prone networks, like cell phone data and Wi-Fi. The only relation this has to the Internet is that it can carry TCP/IP traffic, just like Ethernet, Frame Relay, ATM, and any number of other layer 2 protocols can carry TCP/IP.
