Comment Re:Glitchless streaming. (Score 1) 158

One way that might help is to use DSCP to assign classes of service to traffic. The problem, of course, is that DSCP can be abused. With proper settings things like bittorrent or downloading files would be assigned a low priority whereas voice traffic would be assigned the highest priority. I do this internally on my own network for upstream bandwidth so my backup traffic does not interfere with other data streams. It also means that no matter what someone may be torrenting it won't affect higher-priority traffic. Right now all traffic is basically treated the same with some heuristics to try and optimize different traffic streams. As long as there's no congestion there isn't any problem. When congestion occurs, though, things break down.

I think many of us would like to see traffic managed in a fair but responsible way where for example an ISP doesn't give preferential treatment to one video provider over another.

The problem with all of this is that it requires trust that the content providers are properly marking their packets, i.e. someone isn't marking all their bittorrent packets as high-priority.

There is no cap on the device to be "destroyed" in this case since there is no diode going between a data line and +5v. In fact, the way that the "killer" device is designed the -240v will just be shunted directly to ground through a diode. I'd be more worried if it were +240V since the zener would also be involved.
The caps on the killer device don't hold a lot of charge since they're rated at a minimum of 240V unless they're quite large. With capacitors there's a tradeoff of voltage vs capacity for a given size. I'd argue that the device would be far more destructive if it pumped -12v instead of -240v since it would be able to output a lot more current.

Actually the schematic I'm looking at uses a Littelfuse SP3011 protection circuit for USB 3 which uses a zener diode. It clamps the voltage to ground and the zener and can handle spikes of 40A and +/- 8KV. The nice thing here is that it protects any spikes from being sent to the power supply.

Comment Re:EV dongles? (Score 1) 72

Dongles tend to be a lot heavier and difficult to manage when dealing with that amount of power. There is an adapter for Tesla to use ChaDeMo and it's fairly large, in part due to the huge size of the ChaDeMo connector compared to the Tesla connector. There is also the problem where this charging standard uses a much higher voltage than CCS, ChaDeMo or Tesla standards which all use a similar voltage range.

It makes every sense to tax corporations since they rely and use government services at least as much if not more so than individuals do. They rely on government to enforce contracts, patents, copyright. They use government built roads. And government has to clean up after them when they make a mess and declare bankruptcy. They also rely on government funded education for their workers.

Comment Re:Correct, those jobs are not coming back ever (Score 1) 600

It's the difference between Hillary and Trump. Hillary talked about job training for future jobs where Trump talks about going back to the past. We're manufacturing more than ever before in this country but most of the manufacturing jobs have been automated. It takes a fraction of the number of people today to build a car than it did decades ago despite being an order of magnitude or more more complex. There are manufacturing jobs, but they're not the sort of jobs one can just jump into with only a high school education. Like you said, a lot more jobs will be disappearing and people need to prepare for this. If Trump tries to force the jobs to come back he'll be in for a shock when people riot with sky-high prices at Walmart and find that they're not qualified for the jobs (which is the case today). Manufacturing is hiring but can't find enough people with the skills needed.

On another note, it's the wrong time to suddenly spend a bunch of money on infrastructure since the country is already near full-employment. This is especially true of the infrastructure Stephen Bannon is talking about, like throwing everything against the wall and seeing what sticks. He mentioned, for example, building shipyards, but there's a glut of ships and they're cutting them up due to lack of demand. Spending a bunch of money on infrastructure right now will lead to a lot of inflation. If you're going to build infrastructure you need to be smart about it and look at what will provide a good long-term ROI. Then there's the problem of when you stop building all the infrastructure due to the huge deficits; now suddenly a lot of people will be out of work. Some infrastructure makes sense, but not on the scale Trump is talking about. For example, we really need to invest a lot more in rail and fixing our transportation infrastructure as well as encouraging more broadband and clean energy and improving the grid and water infrastructure.

Nobody in their right mind is going to invest in coal today, especially clean-coal, not when natural gas is a lot cheaper. It's the same with nuclear. The expense is just too high. Hell, wind power is now cheaper than coal, even without the subsidies. Nobody mentions the fact that "clean coal" is a lot more expensive than regular coal either. It's just a marketing gimmick to try and make people think that coal isn't as dirty as it really is or that it's going to change, which it won't. If Trump really wanted to help the people in coal country he should encourage other businesses to move into the area to diversify, that way people are not dependent on any one industry since industries come and go.

Warming water also raises sea levels. Water is most dense at 4C. Raising the temperature causes it to expand and hence sea level rise. Much of the deep ocean is at 4C due to the higher density and this cold water is formed at the poles. According to the IPCC, thermal expansion accounts for about a quarter of observed sea level rise between 1961 and 2003. Between 1993-2003 thermal expansion accounted for around half of the sea level rise.

I too find his remarks highly racist. I've been working in Silicon Valley for 20 years and at all of the companies I have worked at there has always been a large percentage of immigrant engineers of all races. Most of the start-ups in the valley were started by immigrants and 51% of the billion-dollar startups were founded by immigrants. While some companies seem to abuse H1bs I can honestly say that in my experience there is a shortage of good engineers, at least for the areas I work with (high-speed networking code, embedded processors, bootloader code, Linux kernel code, etc.). There are not enough Americans graduating from college with the degrees and skills needed to fill the gap, especially as the older engineers start to retire.

Like the above poster, we see far more foreign born applicants than native born. Unlike some companies which hire a huge number of H1b's who aren't all that skilled, my employer tries to be picky and hire good engineers and we jump at the chance to hire truly great engineers, regardless of race, sex, etc.

We are a country of immigrants. Immigrants help make this country great, bringing new ideas. Silicon Valley has always been a land of immigrants even as far back as the gold rush, where Chinese were brought in through San Francisco. My current employer, as were about half of my previous employers were founded by immigrants.

I say this as a native-born white guy who was born and raised in Silicon Valley. I work with a lot of very talented engineers from all over the world, including many from south-east Asia. In every engineering position I've held, I've been surrounded by "minorities" and am often the minority. Steve Bannon is a disgrace.

Comment Re: he bet on the winner (Score 2) 820

Its purpose has long since passed. Originally there was not direct voting for President.

The whole electoral college system and winner-take-all state behavior severely distorts the election. Because of this setup, the candidates typically only focus on the swing states and completely ignore the needs and wants of other states which might have significant votes that just won't reach a majority in that state. For example, because of this Republicans will ignore the wants and needs of states like California and New York and Democrats will often ignore states like Texas. By eliminating the electoral college and making it a direct vote the President needs to consider the concerns of ALL of the states. While, say, a democrat won't get a majority in Texas, they still need to focus on the needs of the state because the votes still count from democrats in the state.

It also hurts solidly red or blue states when their own party candidate wins because they know they're going to get the majority votes anyway.

My sister similarly has major health issues and relies on a number of provisions of Obamacare in order to stay alive. Losing insurance for her would be a death sentence. Several provisions of Obamacare are helping to keep her alive and a productive member of society:
- Nobody can be turned away due to pre-existing conditions.
- All medications must be covered (minus deductible) though some may require petitioning.
- No lifetime limits on care

As it is, my family has to help subsidize her care since the monthly deductible on one of her medications is $500/month and she's on a teacher's salary that doesn't pay a lot. Without insurance her medication jumps to $5000/month.

My mother also at one time had to have a procedure similar to an abortion when the fetus died and had to be extracted. If they're so anti-abortion, why not work on ways to make it much less needed by offering more birth control and pre-natal healthcare to women? To me it just seems that they want to make women second-class citizens by legislating their bodies rather than help make it so the procedure is needed far less. People like Pence also seem to go out of their way to make it harder for wanted children by fighting against programs like CHIP.

I agree with you on the basic income movement.

Requiring everyone to work full-time for basic survival is just not sustainable in the long term. The capitalists montra of constant growth also is not sustainable since at some point it will have to reach a steady-state. While there are those of us who are highly technical, there are many things non-technical people can do with their creativity if they had a minimal living wage. People could take more risks in harnessing their creativity if they knew that if they fail they still have a base to fall back on. I think you could see a lot more artists and artwork. You almost need something like the WPA of the 1930s to employ artists and other people who otherwise wouldn't have jobs. The other thing that has to happen is the cost to get a college degree needs to fall, either through subsidies or other means in order to get more people with the needed skills.

There are a lot of openings for people with the skills for advanced manufacturing but not enough people to fill them. Bringing back the shop classes and properly funding them in high school as well as more trade schools would help a lot. There are plenty of things that can't be automated that don't require college degrees either but do require skills that often are no longer taught in school.

A basic income could lead to even more innovation and entrepreneurship since there would always be a fallback.

This would require a much better social safety net and a more socialist type society where basic needs are always met.
