  1. Homeschooling Statistics Source:National Household Education Survey, U.S. Department of Education, National Center for Education Statistics March 2013 An Evaluative Study of the Academic Achievement of Homeschooled Students Versus Traditionally Schooled Students Attending a Catholic University
  2. Average of Right to Work states purchase power = $107.43 Average of non-Right to Work states purchase power = $98.31 That extra 3.2% is not looking very attractive.
  3. How long did it take you to change all those light bulbs? You no doubt would have jumped right on the Eugenics bandwagon.
  4. The samples are only 500 per day. The trend is roughly an order of magnitude smaller than the sampling error. There is no discernible trend.
  5. From BLS: https://www.bls.gov/news.release/pdf/ecec.pdf Private industry workers make almost 30% less than state and local government workers making the 3.2% a bit of a joke.
  6. How about this: 1024 GB is not the precise number. It is actually 2^40 bytes = 1,099,511,627,776 bytes. There are 8 bits to a byte so 1,099,511,627,776 * 8 = 8,796,093,022,208 bits Now divide the bits by time 8,796,093,022,208 / 2,592,000 = 3,393,554 bits/sec The precise numbers are: kilobyte = 2^10 = 1024 megabyte = 2^20 = 1,048,576 gigabyte = 2^30 = 1,073,741,824 terabyte = 2^40 = 1,099,511,627,776 Transmission speeds are always specified in bits. Unlike files sizes where 1kB actually equals 1024 bytes, 1kb/sec is equal to exactly 1000 bits/sec. By convention: B = bytes b = bits
  7. 1024 GB is bytes .404543 Mb/sec is bits There are 8 bits to a byte Converting 1024 gigabytes to bits: 1024*8=8192 Gb
  8. Based on 30 days in a month and 8 hours a day you would have to be using an average 9.5 Mb/sec to hit the 1024GB.
  9. Continued due to 'Quote' limits: IOW, if it's broken it doesn't work. Good observation sparky. They are called packet buffers. Of course we all know you know more than Cisco. Sure, that is why a Cisco Catalyst 3750X-48P-S 48-Port Gigabit Ethernet Switch will set you back a bit more than $10,000. Cus we all know it's just a bigger version of that crappy little $50 router/firewall you have. In reality they don't nor do they have to. For example, TW has a number of IP address blocks assigned to them. All the switches that are operating in Layer 3 will have routing tables that know where to send any packets destined for a address in their network. If the address doesn't match any of the IP blocks assigned to them the last entry in the routing table will send the packet to a external connecting network (usually tier 1). The tier 1 network doesn't need to know the exact destination either. All the tier 1 network needs to know is what provider has the block of numbers that contains that address. So when I sent a request for Google TW looked at the address and determined it wasn't on their network. They then passed it off to XO Communications (a tier 1 network). XO Communications knew by the address that the number was in a block assigned to Google so they send it to Googles network. Google then routes it through their network to the correct location. Wrong again. Routers don't assign addresses. Addresses are either assigned static or by DHCP. You are confused because you home 'router' is actually a combination of a switch, router, DHCP server, and NAT firewall (and perhaps includes a WAP) and you apparently don't understand the different functions. In the commercial world these functions are not usually combined in one box. Once again, DNS simply resolves the IP address with the domain name and sends it back to you. I don't work with modems every single day as I don't work for the cable company. When you have nothing better you resort to insults. Good to know. The addresses for the modems are assigned pretty much the same way everything else gets an address. Either statically assigned or by a DHCP server. WTF are you talking about. Are you once again confused with the difference between a modem and a router? It appears so. A modem is a Modulator/Demodulator for converting your Ethernet signal to one compatible with their coax. The cable company has a Modulator/Demodulator at the head end that converts the signal back to Ethernet. FYI, here is an example of how to create a configuration file for a modem. They don't monitor your modem because it isn't a function of the modem and they don't give a crap. You could measure your network traffic but it won't be done using the modem. If your modem is one of the combination router, firewall, DHCP server, and switch too bad for you. The go to tool for capturing network traffic is an open source project called Wireshark. Commercial firewalls only have limited packet capture capabilities and usually don't supply the detail or tools Wireshark provides. Your insults are only exceeded by your ignorance.
  10. So you don't know the difference between DNS and routing. Not that I am surprised. Let me educate you. Routing is based on IP addresses. DNS translates domain names to IP addresses. Nope. DNS servers translate domain names to IP addresses. When you type www.google.com into your web browser a request is sent to a DNS server. What happens is eventually you get a response back with the IP address. At that point your use of the DNS server is done. Your web browser uses the IP address to send your request to google. In fact, if you know the IP address you don't need DNS. Simply type the IP address in the address bar of your browser and you will get there just the same, actually faster as you avoid the lookup. Computer (and DNS servers) maintain a cache of recently visited web sites and their associated IP addresses so you might not even do a DNS lookup. Here is a little video on what and how DNS works. No. The company I work for has exactly 3 which are not public facing. I have just shown unequivocally that you don't understand either how DNS or routing works. Lot of hand waving going on by you. On any given link the speed is set. It doesn't matter how many packets you send. Perhaps you should have read the Wiki article you linked to. The bit time is determined by the link speed. Every bit on a given link takes up exactly the same amount of time.
  11. There is no server. Perhaps you should learn a bit about networking before you ramble on about something you obviously know nothing about. They don't "slow down a request". All the packets travel at the same speed. What they do is limit the number of request you can make over a given time period. The person with the higher speed can send more packets over the same given time period. All packets go through the buffers. Generally first in first out unless QoS is involved. It is called stored and forwarded. It is stored so the switch can figure out where it is suppose to be sent. There are some basic networking resources on the Internet. You should check them out. What is silly is you have not the first clue how networking works yet you persist in making a fool of yourself. Again, your ignorant. A modem is not a tool to look at network traffic. Let us know when you have a fundamental understanding of how networks work.
  12. One problem. Google is not a tier 1 (Internet backbone) provider. This means that Google in fact has to pay a other providers to reach other networks. I did a traceroute to Google from TW. It goes through XO communications which is tier 1 provider. So in fact Google has to pay XO communications to get to me. Other tier 1 providers are Verizon Business, Sprint, AT&T, Tata Communications, Century Link and TeliaSonera (this is not an inclusive list).
  13. More like political reason. The extra bandwidth is cheap, a subpoena from the state Attorney General not so much.
  14. Everybody hates the cable company. Right? So if they are paying for 25/5 and get slightly higher it is one less thing for people to complain about.
  15. How - With cable modems the provider uploads a configuration file that contains the speed limits. Why - Any network has limits. The switches and router have buffers that store and forward packets as they come in. If the number of packets exceeds the buffer size subsequent packets are dropped. TCP packets end up having to be re-transmitted, UDP packets (typically voice and video) are simply lost. Every modem has speed limits that are set by the configuration file when the modem is registered.
  16. Time Warner (now Spectrum) sets your max speed based on what tier you are paying for. I have run speed tests on hundreds of Time Warner connections for customers and the results are always consistent with the tier they are paying for. It you are suppose to get 5 up you might get 5.2 on a good day. The speeds tend to run a little higher then the quoted tier speeds.
  17. I thought you were talking about Obama.
  18. It was like someone else was wearing his jersey. Wasn't the Kyle I am used to seeing.
  19. For the players it is far more complex since they play in more than one state. Interesting read: http://www.bankrate.com/finance/taxes/taxes-cost-professional-athlete.aspx#slide=1
  20. And what makes you think behind closed doors the Trumps are not the same?
  21. Not being able to prioritize traffic is about the dumbest thing you could propose. See VoIP.
