    And with the port disabled how exactly do you expect IEEE 802.1x to work? The port is down. Ie it's down at layer-1. 802.1x happens after all 802.3i, 802.3u, 802.3ab or 802.3an processes have been completed.

  2. Re:Who cares? They don't max out DOCSIS 1! on Comcast Promising Ultra-Fast Internet · · Score: 1

    It doesn't matter if you are maxing our your DOCSIS v1 connection. We cable companies have to increase speeds on our upstream and downstream interfaces on our CMTSs to serve the ever-growing number of users. You local HFC node ends up on a pair of shared upstream and downstream CMTS interfaces back in the headend. We have to increase the channel width and choose higher QAM modulation profiles to stay ahead of the bandwidth curve. At some point breaking up the neighborhoods into more nodes becomes unreasonable (CMTS interfaces aren't cheap). At some point we have to force the v2.0 upgrade and then the v3.0 upgrade. Not only that but large cable providers, Comcast being the most obvious, must migrate to v3.0 to let them use IPv6 to manage their CMs and STBs. They have nearly 100 million CMs and STBs combined. That far exceeds the available RFC1918 addresses. At this point it really isn't about you. It's about the network. Eventually your bandwidth needs will require v3.0 but in the interim the NSP will utilize the features.

    FiOS is PON which is shared (search on the second link for "shared"). The only non-shared fiber medium is simply Ethernet. Most vendors call it Active FTTx. Others call it Active Star Ethernet. When it comes right down to it, it's just Ethernet. It's an Ethernet switch usually with SFP bays for modular optics (though not always as in the case of the Pannaway BAS-500).

    FiOS is not being designed for IPTV. Verizon's FiOS video offering is almost entirely RF modulated on 1550nm. VoD, the guide, and other interactive features are provided via IP (unicast) but all normal video functions are not IP. The underlying technology in FiOS does not have the capacity for IPTV unless MPEG4 is adopted and even then it will only have the capacity for a few more years until data speeds intrude upon the bandwidth needs for video. GPON is capped at 2.4Gbps and again is a shared medium not only by user on but also be traffic type (ie voice, video and data share the same pipe). You can always go with smaller splits (16 or even 8 instead of 32) to lessen the number of subs per splitter. However Verizon and the other large telcos are more concerned with getting more FiOS service out in the marketplace and not on the quality delivered to an individual sub.

    I know this because we spent the last 8 months studying FTTx options, going through vendor dog and pony shows, RFP process and the ultimate purchase. We went with Occam's active Ethernet solution, giving us a full non-shared 1Gbps to the doorstep. That should be amble growth for the next 3-5 years, even in this small market. Our video solution will be IPTV when we're ready to implement it (RF modulation isn't a viable option with the Active Ethernet so no vendor has implemented it).

Most importantly I didn't want him or his mother and their lack of worldly senses to ask in the middle of a family dinner why one of my friends has chosen to make her nickname "High Class Ass" or why I have a picture of me drinking beer (New Year's Eve party) or talking about a recent date.

  9. Record the speed on the dashcam on GPS Used As Defence In Radar Speeding Case · · Score: 1
    This is something that I've mentioned dozens of times of the years. Why don't all law enforcement agencies record the speed currently being detected on the dashcam video output? It's quite trivial to overlay these figures onto a video feed and in fact I know that some depts already do this. Watch the dashcam recordings carefully next time you watch Cops and you'll see a few of the videos with a changing #s in the corner that corresponds to speed of both the officer and the target on the other end of the radar gun. This simple little change would mitigate the possibility of a bad LEO adding a few extra mph to your ticket.

    In addition to that small change why can't the radar gun be fitted with a camera so that the LEO can prove in court that he was in fact aimed at the correct vehicle. My uncle told me about an incident from his youth where a car in front of him was speeding and was clocked by an LEO in an oncoming car. The speeder turned right as soon as the LEO passed (the LEO had to turn around and go around traffic to get back to where he though the speeder was in line). My uncle got pulled over based on the other guy's speeding because they were driving similar looking vehicles. A camera aimed down the barrel of the radar could have proven that the clocked car was no my uncle's car.

    2 fairly simple things LEOs could do to make their work more verifiable. The first adds little cost. The second is another video feed to record and that adds more cost. Both would be extremely useful though.

    Horse shit. My father doesn't smoke, drinks in moderation, stays in shape by working his ass off everyday. He was diagnosed with a pair of leaking heart valves when he was in his early 30s and underwent open-heart surgery to replace one of the leaking valves 2 years ago. He was 48 at the time. My grandfather had open heart surgery the year before. He too had a leaking valve. The doctors marveled over how a 75 year old man had the blood pressure and cholesterol level of a teenager. My great grandmother had heart problems. My great uncle had heart problems. Ditto for a great aunt. Same thing for a cousin of mine. I fully expect to be diagnosed with a leaking valve inside of the next decade. It's hereditary, not because we eat nothing but bacon and drink our supper.

    Another plus is what you can do with employee medical expenses. I forget whether it was a C-corp, S-corp or something else but I read an article a couple years ago about a father and son in a business together. The son had some debilitating illness that the family insurance wouldn't cover. The father got insurance for employees through his corp. He made his son an employee (I'm sure the son did something for the company) and paid the medical expenses. I believe I read about it on Motley Fool but I can't be for certain.

    Yes, doing contract work can be a major boon for your bottom line. I've done quite a bit of it in the past and always faired well come tax day. You can declare all kinds of expenses if you know what they are. I never depreciated any of it. I took it all lump sum that year. It worked well for me. I even did the home office thing the year that I worked from home. That worked out well too. Keep good records though. An audit will hurt no matter what but not being prepared with a basic amount of paperwork housekeeping will be a real bummer when the IRS comes knocking.

    It's also important for non-contract employees to know what they can deduct as non-reimbursed employer expenses. My employer creatively reinterpreted the company mileage policy to exclude my 52mi/day to my customer's site as non-reimbursable even though it still qualified under the IRS's rules. I ended up declaring almost $7000 in mileage last year. I also declared my professional journals, professional memberships, professional development items (books, lab gear, tests, etc) which amounted to another whopping sum. In total I declared almost $17,000 in expenses last year and I'm not a contract employee. Oh if only I was...

    Call up your local ILEC and request a dry pair, aka a dry pair. Get it connected to a remote site that does have access to cable or DSL within a 17.5k foot distance from your home. If you've lived in the area for 20 years you surely have a friend closer to town that you can call on. Terminate the dry pair at his house. Equipment for setting a small scale point-to-point DSL network across the dry pair between the sites can be had in a online for about $200-300 per end. You can also pick up long-range Ethernet (LRE) equipment for even less and possible have more throughput. Now you just have to get Internet access to your friend's house. In all likelyhood they already have Internet access. You could pay for a second connection. You could also just pay to bump up the speed of their existing service.
