I would not be too surprised if components used in this device come out to total price range of 5k€-10k€ in one-off quantities, which paints the price in different light.

Often the show goes out of its way to somehow emphasize that it is a Tesla (shot of door handles popping out, namedropping in dialog...), I haven't noticed that so much for other luxury brands.

I noticed interesting and opposite pattern in various TV shows: when somebody drives a Tesla then he is at least morally shady if not outright bad guy. And it looks like that is intentional.

RS-232 and all the weird and wonderful mostly passive adapters... (mostly caused by the fact that connectors on IBM PC have the logical, but opposite from everything else, gender) Just this weekend we did a cleanup of our office and thrown

The reason for M2 to ethernet adapter is that nowadays there are many boards intended for routers with M2 slot and putting an ethernet card in there makes much more sense than whatever use the slot was originally designed for.

USB to microSD adapters are so cheap, that very often Kingston microSD card is more expensive than the same card in SKU that also includes the adapter.

For me the main issue with C++ is the idea of no overhead for features you don't use which is not bad idea, but is complete nonsense when the measure of “overhead” used by the language authors is some combination of how the hypothetica

The quote seems to be about the compiler/environment being permitted to offer GC, ie. permits you to write C++ implementation on top of some GC'd runtime. It does not say anything about you as a language user having enough introsp

The fact that attacker can cause dissociation is separate vulnerability slash wifi design decision. Detecting active attackers doing exactly that is in fact (literal) text book example of what statistical IDS does. The question of what exac

To summarize the mechanism: the affected chips will transmit packets that are waiting in the Tx buffer even after the station was disassociated and because the station is disassociated (and thus the encryption key was zeroized), these packe

I think that there is really good reason why you don't want to do any of that: bash shell and not general purpose language/VM. And I say that as the author of what essentially is point of sale system implemented in bash with ui ba

In fact there isn't any hardware to speak of (3 bits worth of architectural registers and bunch of trivial logic related to that?) to support vm86 mode, and that is to some extent the consequence of how true real mode is implemented. T

The rules apparently (since last year or so) are that you can interpret arbitrary code as long as the code in question not only legally but in practice meets the definition of the zeroth FSF's rule (notice that the “executables” on the

Tracing JIT tries to synthesize graph of all distinct execution paths (in practice for some smallish value of “all” at a time), ie. there is no sliding window. In comparison OoO CPUs try to execute as much as possible of instructions they s

That depends by what you mean by “modern”. And the age of the system of question is completely irrelevant to whether it is or isn't an unmaintainable legacy mess.

The reason for huge magnets is to drown out effects of external magnetic fields which would otherwise cause spatial uncertainty. For me this seems like something that can be partially compensated for in software postprocessing given fast en

I would not expect return to RTL/DTL but iwould not be surprised by use of NMOS-style pull-up transistors/resistors in combination with traditional CMOS logic. You can make NMOS gate in CMOS process quite easily and it comes out s

I cannot find any information about whether one of the peripheral processors in CDC 6600 (which were full-blown CPUs, not glorified DMA engines as in Cray-1 or System/360) has some kind of system management role. On the other hand Cray

One notable thing about the constant power draw of ECL and Cray-1 in particular is that power draw is constant enough that the logic supply is unregulated, just rectified and filtered output of 400Hz transformers (placed physically in the &

Almost all modern fast serial interfaces are descended from ECL. Often with a twist that while receiver is ECL/CML-style long-tailed pair (which is the obvious implementation of comparator), the transmit side is normal CMOS totem-pole

MSVC in C mode is essentially C89 plus extensions needed to compile C++/C99-isms present in Windows SDK and DDK headers. And Microsoft seems to be mostly interested in whether the compiler is able to build NT kernel and drivers and not

The question here is why you would host such a device for free instead of just having SFI peering with apple (which is apparently required in this program). I suspect that the incentive there has mostly nothing to do with transit costs and

The focus of Nintendo on gaming and not technology is even larger that it seems, because the hardware and software engineering of at least Wii and WiiU (and probably even of GameCube and Switch) was almost completely outsourced.
