Comment Completely false assumption (Score 1) 153

This article and summary are coming to conclusions that are completely false. This stupid little port is just a USB variant, and the only reason Apple has even acknowledged it is that only certain connectors can be used on the ends of "MFI" certified products such as cables and accessories. They in no way intend to put this connector on the iphone, but it is in wide enough use that they dont want to exclude someone already making a product that uses one from paying them that sweet MFI license fee.

The MFI program itself is and has always been the reason to hold back from a USB-C phone; it makes huge revenue for them. With lightning they have leverage to force the MFI licensing. If it becomes valuable as a brand/mark on its own and consumers look for it when choosing accessories then maybe they can safely switch to USB-C.

The problem is that the grey market is so accessible that genuine licensed products have trouble competing even if they make a superior product and follow all the rules. The whole thing is locked into a catch-22 where consumers appear to want the change but are also the obstruction to making it, at least from a business perspective.

I can tell you though that based on the quality spread I've seen with USB3, HDMI, DisplayPort junk that's out there now I would be very delighted to see some kind of consumer-oriented quality standards program emerge. I won't buy 10GbE cables that arent properly tested and certified and these new consumer standards are all equally demanding.

Just for reference the important caveat is no logic that can encode basic Peano arithmetic can be consistent and complete. There are plenty of axiomatic systems that are complete and consistent, even complicated mathematical ones (the first order theory of complete ordered fields, a.k.a. the real numbers is complete and consistent). Also a stronger logic can prove the consistency of a subset contained within it. Thus the first order theory of Peano arithmetic can be proved to be consistent via second order logic. Finally you may also want to look up Tarski's indefinitability of truth -- a theorem which gives the results you have here as a corollary, but is simpler: in sufficiently power logical systems you can't even define a truth predicate.

You are simply mis-reading what is stated in that document. The US citizen parent had to be resident in the US for ten years (prior to the birth). How can I be so certain? I am in a similar category, but was born outside the US to a US mother and a father who had not been ten years resident in the US. I had, since birth, US citizenship until I renounced a few years ago.

Comment Dear Apple (Score 2) 130

Dear Apple,

How about making products your customers actually want? Like a MacBook Pro that's actually a pro-level computer. Or, a "Cheesegrater" Mac Pro with Thunderbolt and USB 3/3.1?

See, here's the deal: no one wanted the trash-can Mac Pro. We wanted the existing model with the I/O capabilities you put in your home-user machines. But, it's too late. You've lost us. We're tired of paying premium prices for last-years already outdated technology.

And you guys are really missing the bus with your lack of VR-compatible hardware. Sure, VR might be a flash in the pan, but isn't the fact that you make NOTHING with the CPU/GPU power to support it worrying?

Submission + - Ask Slashdot: Where to go in IT today?

An anonymous reader writes: In about a year I (hopefully) will have finished a bachelors degree in applied computer sciences, specializing in internet technology. The curriculum is rather broad, ranging from systems programming on a raspberry pi over HTML/CSS/Javascript/C/Java/JPA/Python/GO/node.js, software design patterns, basic network stuff (mostly Cisco) and various database technologies. With these skills under my belt, what career path should I pursue?

I'm looking for satisfying and rewarding work, pay is not that important. While the lectures are interesting and I am able to maintain good grades rather effortlessly, I'm not all that interested in doing a masters, at least not at the moment.

As a side note, I am working already part-time as a system administrator for two small companies, but don't want to stay there forever because it's basically a dead end position. Enjoying the job, though.

I hope for some insightful comments from the slashdot community. Thanks!

Comment Re:Performance? (Score 1) 85

Your information is highly dated and perhaps your sources are also a bit biased. At any rate, 100x performance hit is stupid wrong.

Static translation was achieving 50-70% native performance rates (measured against clock cycles) with FX!32 on Windows NT for Alpha in the mid 90's. The problem of course has been very well studied since then particularly with the advent of virtualization and the x64 instruction set and the need to enhance the performance of x86 code running on even Intel's own platforms. Furthermore for any particularly glaring issues that are the fault of the hardware -- well it is much more easily tuned today than it once was. A bespoke opcode or extra register to assist in a specific task is no longer a monumental engineering undertaking today -- it is a matter mostly of dev/test/validate.

The approach taken with x64 to support x86 native execution is quite different than attacking the problem with emulation. Is there a performance hit? Certainly, but a hit of 10-20% simply doesnt make up for the fact that you might be able to have an 8 core ARM for the same price and power budget as a 2 core x86 mobile cpu. The applications that lose in this scenario are the ones the rely on raw single thread performance. Certainly some games are in this camp, but many games which make efficient use of threads are not.

Comment Hopeless battle (Score 1) 310

In-car systems such as this are a hopeless battle. There is absurd vendor lock-in because there are a whole of 2-3 companies who have built a technology base big enough to be able to offer a system that can be custom assembled for a particular year and model of car. This will then be deployed in about 100,000 cars at best and will never ever be updated or serviced after about 6 months unless there is a vehicle safety issue.

I'm not sure what the exact solution is, but in one way or another there needs to be a mandatory open standard to allow a 3rd party device to show information on vehicle displays, receive input from vehicle control interfaces (steering wheel buttons, touchscreens, etc) and interact with other auxillary systems. We have things like CarPlay and Android Auto, but despite manufactures pledging broad support, very few cars are actually being sold with such capability.
