Early C++ implementations used setjmp/longjmp to support exceptions, and then each try block would lead to settting the setjmp context. So there definitely was a runtime overhead, even with no exceptions thrown. I don't think it&#

I'm French, so this will definitely color my judgement. I find English to be rather simple. The grammar is as simple as can get, and due to it being the international language people are very open to weird accent (including ze frrrrenc

You can use the stable version too, at least ABP, Ghostery and Self Destructing Cookies works fine on it.

Lawful intercept gives access to all communications going through the BB in clear, as well as position. On top of that a BB exploit could in theory (with no IOMMU protection) provide access to the full system memory, and I agree with this.

That's an exaggeration. The carrier cannot get access to the application processor memory, even if the baseband processor itself has access. There is no such standard interface for that, and no baseband maker would do it. Why take the

Then we should have higher social mobility in the US than in France right? But it doesn't seem to be the case (look for "Country comparison"): https://en.wikipedia.org/wiki/Social_mobility Note also that

The transmit power budget allowed by the standard is shared with the various antennas at least. Even if a given transmission uses the maximum power to maximize the modulation and coding scheme used BF will at least reduce the interference t

I have to disagree with your comments on Ethernet: - there is security at the Ethernet level with 802.1x. Mostly used in professional settings, to prevent anyone with access to an area to plug into an Ethernet jack and sniff traffic with AR

Higher frequency means less range (everything else being equal) but not more interference. Interference depends on how used / crowded a given piece of frequency is, and the 5 GHz band is much less crowded than 2.4 GHz: there is more sp

802.11ac is the same as 11n in the 2.4 GHz band. All the new features are for the 5 GHz band, and its support is required for 11ac. At 5 GHz there's plenty of spectrum so wider channels still make sense there. But not at 2.4 GHz indeed

I fully agree. A lot of people say Moore's law is the transistors density doubling every 18 months (or 2 years, it varied). But this misses the economic angle that was present from the start: Moore talked about the density of the least

GDRR5 leverage the fact that the memory chips are soldered, compared to DIMM slots for DDR3. That can be use to improve the performance. Now don't ask me for more details, I'm not an expert in this area.

Yes, and in two ways as far as I understand: 1) you use the LGPG license. Then you can keep your application closed source / proprietary as long as you link with the Qt libraries dynamically and provide your changes (if any) to the Qt

It won't harm the phone, but it won't work either. You can find generic SIM card that you can program yourself, but that's not what is used in a phone. Your phone will only work with a SIM card embedding specific applications

Good question. SMS are transmitted over the NAS layer of the 3GPP stack, which terminates beyond the cell (NB/eNB). There is NAS level security but I don't know if it's end-to-end or only over the air link. Hopefully it'

The architecture is fine. A better explanation would be: if an incompetent operator use obsolete technology then its SIM card can be hacked. But any half-decent should be immune to this (there are billions of SIMs, and here it's "

VoLTE is not deployed yet (but soon). Voice and in general IMS traffic will use a separate APN, per the GSMA VoLTE specification. This spec requires that an APN called "IMS" be used, and Verizon is complying (even today, SMS is do

Hi, it's not so much a feature request than a bug report (sorry if it's not the right place). Since a few days ago the comments link in the RSS feed is wrong, it contains extra spaces. Example: https:/%20%20%20%20/%20%20

The story is presented to put the focus on the Haswell processor itself, and there will be saving there for sure. But I would expect that a good part if not most of the savings will come from the platform surrounding the processor. Intel ha

(See my other comment below too on this topic) You indeed have to understand how the Prolog engine works in order to structure the declarative statements of your code in a way that will lead to an efficient execution. A way to see a Prolog

In both cases I wouldn't say that learning the syntax is the problem. The challenge IMHO lies in the different execution models. And there starting with LISP is likely a good idea, as it's less different than Prolog. It's functional, but st

I'm not sure you can avoid the dependency on the rules order, and having to understand how the Prolog engine works. But I found there is a rather intuitive way to deal with it: think of the Prolog engine as searching a space of possibilitie

Agreed, the small N7 plus a laptop is also my choice. But this is very personal opinion, I'm sure there will be others who like it. Still, I doubt there will be enough to make this a commercial success in the end. The initial reviews are no

Exactly backward IMHO. Use your gut (= your intuition), but don't trust it and use your head (= reason, rational analytical thinking) as much as you can to decide next actions. Of course, with limited time and resources and incomplete data

This paper really looks like sensationalist attention grabbing material, and I'm kind of disappointed to read this in the MIT review without any context or critical analysis. The synchronization signals in LTE are split in two parts, the PS
