    Ah... That money is actually in US banks. The offshore company is the owner of these funds on paper, however they would not benefit from holding the money actually in that country.

  2. As a T-Mobile customer this is great news on Failure of Sprint/T-Mobile Merger Means a Missed Chance To Save $30B (kansascity.com) · · Score: 1

    I like my current level of service. I know it is not perfect, especially when I go to vacations to remote areas, however I get 95% of what I need at about half the price of the competition. Among the competition, AT&T seems to provide similar service with higher price, and Verizon seems to offer better service with higher price. Sprint always seemed the distant last with worse service, with worse price (compared to what I'm getting right now).

    There was some potential in T-Mobile absorbing Sprint and repurpose the spectrum for better combined service in the long run. However SoftBank seems to have a different idea in this merger. I would not want T-Mobile resources used by Sprint to make a worse combination of the two (remember Sprint is losing money, and the way they can make, if they took over TMobile, would be giving less service for higher price).

  3. Not an isolated story on 'We Can't Compete': Universities Are Losing Their Best AI Scientists (theguardian.com) · · Score: 1

    There are too many PhD graduates to fill in the open academic positions, even if you were to include temporary and teaching ones. And since industry companies not only offer good salaries, but often also good research opportunities (even if you cannot publish everything that you do), there is obviously a pull into that direction.

    I had very persistent friends who did multiple post-docs, and temporary positions to finally find a full time professor opportunity. I admire their passion. However that route has a lot of sacrifices, especially if you are starting a family.

  4. Hmm.. I think you're right, I might be looking at the wrong table. Still with 3 wire connector, and insulation, it will still be very thick.

  5. Btw to be be concrete, this is the size of the transformer you need to put "inside" the car, if you want to use current cable thickness:

    http://www.transformerscn.com/...

    (400KVA, 11kV, 100A)

    Or you can use the current car electrics, and have a 1,000A cable, which would have 20in (50cm) thickness.

  6. Thanks, I might be slightly off with voltage numbers.

    However the scale is 10 times of what's possible with the current power delivery systems. In order to charge a 85KWh battery (Tesla) under 5 minutes we need a 1,020 KW charger. Until we find something better than copper for cables (maybe superconductors?) that's some huge ass cables (hgh amp), or huge ass components (high voltage) in the car.

    Also there is the issue of heat dissipation. All "cooling" systems essentially take heat from one place and dump it at another. Since the car is stationary, the "dump" will probably be a single place. Even if we were to lose only 1% (which is unlikely, it's probably going to be much higher), we're talking about a commercial furnace on the other side of the "cooling" system. (Talking about 10s of KW of "loss")

    The battery technology is not the concern here. It was how we deliver the power. If we have a single cell battery in isolation, we can charge and cool it without much issue. When you have 100s of them in a pack, it becomes harder. When you reach the EV levels (7000+ cells), it becomes a very fun engineering problem. Even if the batteries can take in that much charge in 5 minutes, we do not have the practical delivery system (cables, transformers, etc) today.

    I'm not discounting medium to long term discoveries though. For example, again superconductors will solve many of these issues, however they currently exist in cryogenic temperatures.

  7. I like being able to charge that rapidly. However it does not seem to be practical for widespread installations. The numbers just don't add up.

    A cheap (Leaf, eGolf) EV has about 20-30KW battery (giving 80-130 miles range).

    The current widespread commercial chargers are generally 6KW (the kind you find at parking lots, offices, etc). They will charge the car in about 4 hours from a depleted state. (The home chargers are 3KW or even 1KW but let's ignore them for the moment). To get 6KW, the charger supplies 204V @ 30A. (For a comparison, the only other device at your home would be the oven or the dryer that is using the same level of power).

    The "superchargers" provide about 100KW (they range from 30KW - 120KW). To do this they use 408V @ 100+A. However they require commercial installation, since this is more power than several houses combined together. They allow charging 80% of battery under 30 minutes for the smaller cars. Teslas are at the high en of the spectrum (120KW), and they can charge the 60KW versions in just above one hour.

    To get 5 minutes charging we would need to jump to 1,200A @ 408V, or 100A @ 4080V. The first choice is not practical. (At 1m this requires a cable width of 50cm! / 20in). The second one requires larger electric components in the car. Also even with 1% loss due to heat (which is wishful thinking), the excess heat would be 10KW, which is in the commercial oven range (i.e.: standing near the cable / car would easily roast a chicken, or make kabobs).

    Overall it is nice to think about these technologies, however there are limits in physics that make this very impractical in the short future.

  8. Re:tl;dr on The Real Inside Story of How Commodore Failed (youtube.com) · · Score: 2

    Windows etc was flawed. However they were less bad compared to their competition.

    - For example, with all hype and features, OS/2 would crash on 3rd party hardware.

    - Novell, while working great for DOS systems, was unusable for Windows. And their push for IPX was not scaling well for multi-site networks. And don't get me started for the newer Java based monstrosities.

    - The office alternatives took a very long while to switch to Windows. By that time all new typesetters were pretty much used to Office.

    Basically people underestimated Windows. It had flaws, it would get blue screens, connecting to the Internet would crash it. However it was the only consumer OS viable at the time (I was using Linux of course, however I was a minority).

  9. Lithium batteries are not to be taken lightly on People Are Using Recycled Laptop Batteries To Power Their Homes (vice.com) · · Score: 4, Informative

    They are very power efficient, and also very dangerous:

    - Overcharge it too much: boom
    - Drain it completely, and then try to charge: boom
    - Puncture: boom
    - Overheat: boom
    - Make your own battery with cells you found around, and not use a good controller: boom, boom, boom

    Of course it is possible to use lots of cheap batteries, with a very good controller system. This is what Tesla does for its current cars. However the system needs to monitor each cell and pack, and have safety precautions to disconnect them if them become faulty.

    Basically, do not try this at home.

  10. Re:I'm pretty sure nuclear beats them all on The Health Benefits of Wind and Solar Exceed the Cost of All Subsidies (arstechnica.com) · · Score: 1

    There is a stigma in nuclear. People don't do long term thinking but look at single isolated incident. And the media is helping a lot in that department.

    They want "fair" discussions. So if there is a topic where 90% of the people would agree, and 10% would be ignorant, they would bring in two guests, one from each side. And unfortunately even if one of them is an expert, and the other person is a nutjob, they would present them to be at the same level of authenticity. And the public become more and more divided, the 10% quickly becomes much larger without new scientific findings or any other kind of reasonable proof.

    So if you're going to support nuclear in a public debate, they will need to bring people who are opposing the view. That's fair, but the people they would bring in will not be persuaded by numbers, science, or proof.

  11. If they are going to invest $3 billion in a $10 billion venture, then they should receive 30% equity stake there as well. This will both be fair, and probably a reasonable investment that will bring long term capital to the state.

    However given the history of "socialized loss, capitalized gains" of state - enterprise relations, I'm not keeping my hopes us. Look at what happened then feds bankrolled failing financial institutions during the last crisis. They gave them loans at reasonable rates, sometimes just huge rebates, however the public received nothing in return for taking the risk in these bailouts. We're still on the hook for the huge trillion dollars bill, while the financial institutions recovered.

    We want better connectivity, but less cell towers nearby. We want unlimited data, but no speed limits, We want the latest technology, but don't want to pay for it, etc. T-Mobile seems to have made some sensible compromises on these topics, and they finally have something to show for it.

    They have unlimited 4G, but throttle video to "mobile optimized" speeds. If you want you can disable it, but by default they save data while you are using 5" screen to watch latest Netflix episodes.

    They offer cheaper plans, but don't give free phones. If you want them you need to pay full price (or in installments, but you see what the actual costs are).

    They try to suck up every bit of spectrum they can find. Of course it still does not work when we visit Yosemite or other parks, but it works very well in the city. I have a minor issue though. The plan to implement LTE-U, which will use WiFi spectrum for 4G. Which will make already bad home WiFi connections even worse (can your access point fight a fair battle against a cell tower)?

    Anyways they made enough noise that both AT&T and Verizon started copying them. The competition actually worked (yay!), and I hope we see a similar situation for landline cable service as well. (That's a very long shot).

    This lacks two properties to be useful, especially in the US.

    1. Rich people do not need a "salary", even an "income". They already have "wealth", and "unrealized gains" from their investments. i.e.: they might have a mansion, and own stock in a large company, and receive zero salary but still sustain themselves, their heirs, and maybe three more generations without any additional "salary" (i.e: income tax). In addition to "income", "wealth" needs to be public as well. (But that will attract all kinds of thieves, literal ones, and also "long forgotten family members").

    2. The real discrepancy is between companies, and job levels. Knowing another company in another town giving larges salaries will not help, if you do not properly calculate the cost of living, or the skills required to switch jobs. Of course knowing that the CEO has been paid a bonus, while people are taking a paycut is valuable, but even that will not be very useful. People need proper mobility, and access to education to switch jobs, and climb the job levels. Otherwise it will be idle gossip.

    The "geek" image given on media always helps portray fake ability to overcome anything. Even Star Trek had this: "10 hours, you have 2". I would assume people are thinking "the experts are just lazy, they say it cannot be done, but in fact they are just avoiding the work".

    I'm not sure it will be solved in a short while, once people understand why proper encryption is necessary (i.e: loss of online commerce, or even bank account contents) the sentiment might start to change.

    Or at least it should go both ways. If the employer want to keep me, I should be compensated accordingly, and similarly if I want to stay I need to demonstrate sufficient utility for the company.

    Here in California, we are a right to work state. They can terminate me tomorrow, and I reserve the right to leave anytime (with a customary two weeks notice, but that's not strictly necessary). This keeps the balance, so that I keep working, and they provide good benefits, as long as we want to continue the relationship.

    Of course the situation is not perfect, but I think this was one of the drivers of Silicon Valley's success. People form, disband, join, and leave companies all the time. The ideas flow, and good products are generated.

  17. And here I am paying up to 45c per KWh for the same energy, thanks to the same power grid. It is more then triple the national average, and I could use some extra power for my A/C during the hot days (we had several scorching heat waves in the recent weeks).

    California seems to have very bad incentives in terms of public utility development, and we seem to be paying (literally) for it.

  18. One of the reasons GPU mining is preferable over ASIC (and up to a point FPGA) mining is that the leftover GPU can be resold at a used marketplace, keeping some of its value. This is more of a "hedge" against a probable market crash.

    On the other hand dedicated cards have almost no resale value (maybe 10% compared to 50% of a one year old GPU), taking away a huge value from the initial investment.

    Of course there will be some buyers, but I personally will stay away from them, unless they come with a 40% discount (which is very unlikely to happen).

It had an interesting history, and up until they were ready to release OS/2 NT (http://www.os2museum.com/wp/nt-and-os2/) even Microsoft believed in it. However history was not kind at that moment, and MS and IBM split, causing OS/2 NT being repurposed as Windows NT, and the rest of the story is well known.

    NT microkernel had support for separate subsystems (OS/2, Windows, and Unix). Even until Windows NT 4, it was able to run (command line) OS/2 applications natively, in addition to Windows. (This is more or less how the Linux applications run today on the recent "Creator's Update" stuff. They have a separate kernel API for the Linux subsystem).

    However NT took on, OS/2 did not. Mostly due to technical reasons: it was fast, but not stable on most devices, except for a small approved subset, had a single message queue for the system, whereas NT had true multi-tasking, and would not run 32 bit Windows applications, only 16 bit ones. I was sad that this happened, but given many good alternatives today, like Haiku OS optimized for multimedia, Linux for everything else, and yes Windows for desktop, it might not be a big loss.

    Intel C2000 series was a dream come true for low power servers. I have a 8 core C2758 atom server at home (from SuperMicro), and it is really a beast given working at less than 10W total system power at idle or low utilization (excluding HDDs, of course but with the MB, CPU and RAM).

    But they have dropped the ball, now in two ways:

    - There was no update to the Atom server line in the last two years. They probably do not want to cannibalize their other offerings (8 core CPU with AES and VT extensions is more than enough to host several VMs). But they also left the market empty (there is still no competition).
    - Now we learn that the chips are faulty. Without any replacement option (the chip is soldered on a particularly expensive motherboard), I'll just wait for the time it will fail.

    Given they did not provide any useful performance increase in the last two generations, heck make it three, I'm really disappointed with Intel at the moment.
