Satellite Images Show Russians Shelling Ukraine

RatherBeAnonymous Re:Great... (564 comments)

"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.

'Optical Fiber' Made Out of Thin Air

RatherBeAnonymous Re:Little, as far as I can tell [But what does it (115 comments)

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.

Microsoft's CEO Says He Wants to Unify Windows

RatherBeAnonymous Re:Server 2012 already looks like Windows 8. (322 comments)

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.

Verizon's Accidental Mea Culpa

RatherBeAnonymous Re:ugh (390 comments)

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..."

Which means: You are talking out of both sides of your mouth.

Robert McMillen: What Everyone Gets Wrong In the Debate Over Net Neutrality

RatherBeAnonymous Re:Why not both? (270 comments)

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.

When will large-scale IPv6 deployment happen?

RatherBeAnonymous Re:IPv6 Addresses (305 comments)

I do set up networks. I'm not being lazy, I'm being pragmatic. IP4 is easy to work because most people can look at an ip address and break it down to 4 numbers; 4 tokens to remember for the few moments when it needs to be remembered. I'm sure there are people practiced with hexidecimal that will find it very easy to work with, but for most techs a 4 character string of hexidecimal is not an instantly recognizable number, it's a quazi-random string of characters. This is mostly an issue of practice and language skills. The number 746, for example, in hex is 2A1. 746 is easy to remember by saying seven hundred and fourty six. Mentally it is one number. 2A1 does not have any ingrained meaning to most people because most people have not been practicing with hex their entire lives.

I wager that the decision to use Hex will cause a great number of mistakes that would not have happened with a decimal-based notation system. I also wager that this will cause a measurable increase in the amount of time it takes to set up networks because it will flat out take longer to transpose numbers, triple check them, and correct the increased number of errors. In manufacturing, when a large number of errors or accidents happen at one stage of the line, it is because the process is flawed. I believe this will go down in history a significant flaw that causes many errors and waste a lot of time.

Cisco Spending Millions of Dollars Secretly Purchasing New Juniper Products

Or better yet - keep quite and use it to spread disinformation. A little corporate counter-espionage goes a long way.

When will large-scale IPv6 deployment happen?

RatherBeAnonymous Re:IPv6 Addresses (305 comments)

More to the point: use DNS.

This response always pisses me off. What do you do when DNS is broken? What do you do when you are the guy setting up DNS services? With IP 4 it is pretty easy to remember a 4 number string long enough to transpose some addresses. It is easy enough to remember a small handful of well known DNS servers' addresses so that you can get a machine talking on the Internet or on your local network. IP 6 has a short-hand notation, but it's still a pain. Looking at the example given, when transposing that address one has to hold in mind 5 sets of variable-length numbers (in Hexidecimal, no less) and remember the location for the double-colons. The IP 6 designers only answer to this complaint is to suck it up - and use DNS. It is a flippant and arrogant answer.

Cisco Opposes Net Neutrality

RatherBeAnonymous Re:Surprised? (337 comments)

Cisco will get the money either way.

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.

Cisco Opposes Net Neutrality

RatherBeAnonymous Re:TWC is already screwing customers using fast la (337 comments)

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?

AT&T To Use Phone Geolocation To Prevent Credit Card Fraud

RatherBeAnonymous Re:Or call your credit card company ... (228 comments)

True story...

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.

Comcast CEO Brian Roberts Opens Mouth, Inserts Foot

RatherBeAnonymous Re:He also forgot to mention... (343 comments)

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.

How MIT and Caltech's Coding Breakthrough Could Accelerate Mobile Network Speeds

RatherBeAnonymous Re:in simplified terms, it's forward error correct (129 comments)

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.

RatherBeAnonymous Re:in simplified terms, it's forward error correct (129 comments)

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.
