  1. The catch is... on Samsung Testing 5G Phones With 1gbps Download Speed · · Score: 4, Informative

    The second article notes that the 5G tests are being conducted on the 28GHz Ka microwave band. They also note that they're using a 64 element antenna array.

    While those upper microwave bands are great in that you can get very wide channels (possibly hundreds of megahertz wide), their downfall is that they are incredibly line of sight restricted. This is compounded by significant atmospheric absorption. That's why many broadcasters on the band tend to use highly directional antennas. For omnidirectional use, you're going to have to deploy a lot of picocells.

    Also for their tests, are they using the large number of antennas for MIMO beamforming (additive RF amplification), MIMO spacial multiplexing (parallel RF feeds slightly out of phase of each other) or old fashioned directional transmission (or a combi of all three?). How much additional cost is that? Even with fractal antennas on short wavelengths, how many of them can you fit in a handset?

    That's clearly what this boils down to. This massive free-form expansion of TLDs is little more than a revenue generation scheme by ICANN. So the same sort of wild-west name grabs we saw with .com domain names will simply be repeated here, just on a larger scale.

    I'm sure that all of the new issues of domain squatting and trademark conflicts with/within these new TLDs will be addressed by ICANN, that is if you can get them to stop rolling around in their piles of money for a minute.

    I'm no expert on coal power plants but I'm pretty sure we already do that with scrubbers.

    Scrubbers are typically only required for new plants. Existing plants have very liberal grandfather policies that exempt them. So many companies will simply upgrade existing facilities to keep the grandfather clause. It isn't unlike tearing down a house, save for one wall, then building a new house and then saying it is a 100 year-old house.

     

    Maybe not on the horizon but there is certainly something that has been around for 50+ years that could replace coal overnight. It's called nuclear power.

    Traditional nuclear power facilities are expensive. Not to mention that you have to build them in the Styx to appease the NIMBY folks, so you suffer a lot of transmission losses. Thorium reactors might offer a solution. Same with micro reactors that can use a sealed fuel container shipped from a factory. But GE and Westinghouse are still pushing for their latest super-sized traditional reactors.

    Except that the United States has the benefit of cheap methane (CNG). Regionally, you also have cheap hydro in the NW and TV, cheap wind in the upper prairie states and cheap solar in the sun belt.

    Coal is only cheap when you exclude the environmental and related health costs. The heavy and radioactive metals expelled as particulate matter are a major source of cancer. The nitrogen oxides expelled are a major contributor to acid rain. People are sorta forgetting those issues in the whole CO2 debate. Last I checked, chemotherapy wasn't cheap.

    And many areas in the US have restrictions on wood burning. Unless you're talking about a pellet stove with catalytic converter which is fairly darn clean as far as burnin' wood goes as is often exempt from burn restrictions.

    So instead of WINE the environment emulator, the article is talking about WINE's less talked about feature, WinAPI emulation via a shared library (not unlike nt2unix, windu or Willows Twin).

    I've actually used products like this before. It isn't much different than using libC instead of the native OS API. It makes porting from Windows to Unix so much easier. The only performance cost is the thunk to the emulated API. But if you want to port your Windows app to a big iron server (POWER or Sparc), it is the way to go.

    If proxy services are classified as service providers, expect that laws regarding logging and auditing be ramped up

    That has more to do with avoiding detection in the case of private proxy mesh networks.

    If you were running a proxy service open to the public, such techniques would turn up during an audit and would result in revocation of your service provider status. The government could then hold you liable for the content passing across your mesh. They could then test the quality of your whitelists/blacklists by attempting to use your public proxy to access illegal content and then fine/charge you as they deem fit.

    Even in the case of private proxy meshes, all the government would need to do is discover a leaf. They could then hit all nodes talking to that leaf, especially if they discover the leaf in the middle of an illegal transaction or are able to replicate the transaction. They might not be able to get the destination, but they can pick off the internodals in an attempt to discouraging others from doing the same.

    You will have to outlaw it

    You don't need to ban it completely, which would probably be unconstitutional in a number of countries anyway. Instead, give them the choice of instituting a clear chain of client+destination or require strict monitoring of illegal content, which generally does not enjoy constitutional protections.

    That's what I wonder. If proxy services are not classified as service providers, the government could in theory come after you for conspiracy or possibly RICO statutes.

    If proxy services are classified as service providers, expect that laws regarding logging and auditing be ramped up. Every TCP connection you make will be saved and stored for a long time. Even if you bounce across seven proxies, the logs will eventually point back to the client. They could easily require little more than an administrative subpoena to get those logs, too.

    My worry is that in their effort to trace pirates using back channel methods, the government is going to obtain very powerful methods to track you. And we're going to pay for it out of our own pockets.

    Not only have I used BSD, but I'd say that it shaped my adult life.

    As a teen, I signed up for a UNIX timeshare service that utilized a Sun SPARCstation running SunOS 4 (4.3BSD based). You got a Csh and a T1 to the 'Net. When they started offering SLIP service, I installed AmiTCP, an Amiga port of the NetBSD network stack which also included many /bin commands and /etc conf files.

    I eventually took the plunge and installed NetBSD 0.9 on my Amiga 3000. Later, it was FreeBSD 2.x on my 486/66. While most people in my university programming classes were using Turbo C, I was using GCC. Classmates took MFC/C++ as an elective, I took Perl. Friends were using IPX on their home network, I was using TCP/IP with a FreeBSD box acting as a dial-on-demand gateway.

    Having so much networking experience, I drifted from the programming side of computers into networking. My experience with BSD eventually landed me a job with a networking startup that used an embedded *BSD OS as the base for their product. Since then, I've used BSD based gear from Citrix (Netscaler), F5 (BIG-IP, EDGE-FX and 3DNS), Nokia (IPSO Firewall) and Secure Computing (Sidewinder firewall) as part of my job. I've been at it for over 15 years.

    I still use FreeBSD for development here at home. DragonFlyBSD is also nice, though I prefer Ports over Pkgsrc, which is why I stuck with FreeBSD.

    The migration to Linux goes beyond simply bringing games to a new platform. It could be seen as an attempt by Valve to diversify in light of Microsoft's and Apple's closed app store platforms.

    At this point, I consider broadcast television to be a waste of my time. Roughly 25-30% of any given program is dedicated to advertisement. For a 30 minute show, this doesn't leave enough running time to have much depth in the story. You really need the full hour to do much. Even with hour-plus shows, the commercial blocks are now so long that you lose the suspense and drama that builds up, so why bother?

    Also, the ads usually have little relevance for me. The majority of ads I see on television these days are targeted at seniors. That says a lot about the demographics of the people who are still left watching ads.

    So I stopped watching most of the 30 minute shows and now resort to my DVR, Netflix, RedBox and other sources for the remaining content. Hulu really isn't one of them anymore now that they increased their ad count and refuse to make Hulu+ ad free.

    My hope is that commercial supported television dies and is replaced by pay-per-view or subscription models. The technology is there, but media companies have huge ownership stakes in cable companies and are resistant to such change. Also, seniors living on fixed incomes consume a huge amount of television and would resist any change because they often have have little disposable income.

    Were such a shift to occur, a bright spot would be the return of smarter content. Remember that advertisers dislike shows that draw in intelligent viewers because said viewers have better critical analysis skills and therefore are less swayed by commercials. Nix the ads and that barrier goes away.

    I'm sure this is just AMD hedging their bets against multiple processor ISAs. There are places where ARM is better than x86/x86-64, so it makes sense to try and dominate those niches. It falls in line perfectly with AMD being a less expensive alternative to Intel.

    Given that Intel is trying to wind down its StrongARM line it inherited from DEC, AMD may see the ARM line as a place where it can finally be top dog. It has the expertise to give Broadcom, TI and Samsung a run for their money.

    Taking a really big drink from the hypothetical Kool-Aid, I could see ARM64 processors being used as x86-64 replacements in palmtops and laptops. There are a couple of x86 to ARM translators on the market, which would solve the binary compatibility issue. I used FX!32 back during the NT4 and NT5beta days with my DEC workstation, and it made emulated binaries about 90% as fast as native. With advances in JITC translators and a cleanup of the x86-64 ISA to make it closer to meeting Popek and Goldberg virtualization requirements, I could see a good modern translator being 95+% as fast as native x86-64 code.

    I've been expecting Apple to churn out a Power Book with an ARM processor and a binary translator. They did it with m68K -> PPC and PPC -> x86, so I wouldn't be surprised in the least to see x86 -> ARM. Now imagine it with an AMD ARM64 SoC at the heart of it.
