Comment Re:Expensive (Score 1) 107

What version of DOCSIS are you dealing with? Any what number of customers on a CMTS port? Coax might last longer (citation needed, I don't see coax undersea), but how long to the nodes that are needed every couple hundred feet? The only parts that need electrical power in a PON are the ends.

10GPON easily beats the highest tiers of DOCSIS specs (giving the benefit of the doubt by using the theoretical numbers) and even that can't provide a gig per customer once it gets reasonably provisioned with customers.

The biggest problem with fiber's scalability is that the light can only be split so many times before it can't be accurately decoded on the downstream (upstream isn't as big of an issue as it isn't being split). On a cable network you just keep adding nodes to boost the signal and a single CMTS port can now serve more customers (but splitting the bandwidth available even more).

From a customer perspective that difference means that fiber will always outperform coax as network load increases as it can't be overprovisioned to such an extent, the highest split ratio I've seen is 1:128 which means split evenly everyone gets just under 20Mbit for normal GPON assuming you can get everyone proper signal at such an extreme split ratio.

What does this have to do with H1B1s? If they get laid off they go back home and get hired there, the people this hurts are US workers.

Even if you kick out every H1B1 do you really believe these companies will hire in the US or will they outsource to another country? You can only raise tariffs so far before they hurt the US more than the intended recipient.

Uh, no.

Spoofing filters are best setup at the last mile to customers. It can possibly be setup on the interconnections between / to small ISPs where there is no BGP transit going on (hence your BGP filters say what networks are expected, screw anything else).

For the last mile there are the smallest number of variations at that point and limited number of variations for routes. By the time you hit the tier 1/2s who are backhauling hundreds of teras / petas of traffic you will hit not only the limitations of attempting to firewall that much traffic but lots of legitimate reasons for asynchronous traffic flows (most commonly traffic management).

One problem with that theory, they know who he is now anyway.

In this scenario said syndicate might actually be pissed that the flaw is now fixed. He isn't in the police's good books so what do you expect will be the police reaction if he gets approached from such a syndicate now and tries to report it. Sadly my money is on "Oh he was in with the criminals all along".

#1 can be argued under the guise of penetration testing / security research, #3 is a side effect of that (I don't know how much he recorded but he would have needed some proof that he managed to tap into the system).

#2 makes me cautious about this person's character and I agree is a prosecutable offence but if 1 & 3 are charges he got hit with and they stuck the message that got sent is don't alert the authorities sell the hack as a zero day.

Comment Re:So the taxes were collected from salaries inste (Score 1) 262

Doesn't really sound like it, "Hey bob we are either going to loose this money anyway so we will let you have it", does that sound like they really value your work and want to pay you what you are worth?

Its exactly what they are doing with taxes, the added benefit here is they get to look good to their employees in the process. This doesn't sound like honor, its sounds like choosing the lesser of 2 evils.

If you don't know the difference between sales professionals and IT professionals... you are part of the problem.

How do you get to the latter without at least making contact with the former?

Something of the OP's scale isn't exactly the normal thing that your average IT professional has any experience with so the normal channels probably won't work.

Comment Re: Considering how few boys graduate at ALL (Score 1) 355

The question is why?

If the answer is that the small subset of men who enter the teaching field teach better then cool (maybe thats the trend that these institutions have seen). However if it is just to make up diversity numbers and they are worse teachers then that is a very bad practice. I don't have kids but I would want the best teacher for them regardless of gender.

If you change the OS and the manufacturer finds out it is possible that they will not honor the warranty seems like a good reason to not touch the pre-installed OS. Especially when you factor in the system recovery will put said OS right back (assuming you didn't kill that partition during the install of the alternate OS).

Then you open the can of worms that is drivers, quite a few Windows 8 machines lack drivers for win 7 and previous (then again makes a good argument for switching the users to Linux).

I agree with your point (assuming you are talking about a decade ago, I expect the computer access issue has changed slightly) but that doesn't counter the GP's point of the tech industry isn't the one doing that discouraging.

In the 90s (when I was a teenager) girls looked down on geeks (then again so did most of society), allot of the time computer science had the same set of questions to answer as theoretical math "What good is it? What can I do with it?" In the 90s tech was only making large effects in very limited areas. Compare that even to Civil, Electrical and Mechanical engineering; you can see the bridges, televisions and cars respectively. Only recently (say the past 5-10 years) did the effects become easily visible to the general population.
