No, they are not doing this for publicity. Their goal is to improve the review process by attracting more people interested in the topic to the review process and make it more open.

I happened to attend the workshop last year and there was a very interesting discussion at the end about how to modify a review process to make it more open. While I didn't take part in the discussion, there were many aspects considered about the open peer-review process, both positive and negative. For example, some authors might be frightened to submit a paper when sending preliminary versions of their work. The selection of Reddit and ArXiv didn't have any publicity (or political) objective, they were just tools familiar to the people involved in the organization and the discussion.

I am some skeptical to this model, but still is a very interesting experiment so it will be nice to see how it compares to the reviews from previous editions.

Of course the title is misleading! For a user-space programmer, the ISA is completely hidden by the compiler and the system libraries (for example, synchronization). Still, the document makes interesting points, such as different behaviour of the compiler (which apparently removes locks in ARM32 but not in ARM64) which could impact performance, especially for highly concurrent applications.

Comment Re:Double every 4 years and it will take less than (Score 1) 269

You forget the simple fact that no exponential growth can be sustained forerver. Moore's law will come to an end (in a few years, btw), simply when the required size for transistors is smaller than a single atom (or a single sub-atomic particle if we manage to do that; the idea is the same). Dennard's scaling has already hit the wall. Networking will never send data using less than a single photon per bit (actually, the limit imposed by quantum noise is around 15-20 photons/bit) or a single electron/bit, and the amount of them is limited by transmission power. So no, there are some achievements which we won't obtain, because of simple phisical limits. You cannot simply sit and wait.

Comment Spanish SEAT too; CEO climbing in the group... (Score 1) 494

The Spanish brand SEAT, part of VW group, used some 500.000 of these tampered engines. Jürgen Stackmann, the CEO of SEAT is also leaving this company.

However, apparently he is not being fired, instead he will become the group worldwide sales chief (link in German).

Interesting and sad to see how some people are being blamed and fired, while others (in the same position in other company of the group) manage to leave unpunished and even use this opportunity to climb in the group.

Comment Networking blog: ipspace.net (Score 1) 203

I follow Ivan Pepelnjak at blog.ipspace.net for advanced networking stuff (some topics are CCIE-level). He is great at explaining concepts, has strong opinions on new technologies and provides links to background information. He also gives weminars on multiple technologies (most are paid). Great source of information to get in touch with reality, apart from what appears in networking books. (Disc: I am not affiliated with him, but follow the blog and have attended some paid weminars).

Comment Service level (Score 1) 170

It's not just bandwidth, it's also discard priority according to the service class of each customer.

In case of congestion, you'd better belong to the "gold" class (highest paying customers) rather than the "silver" or "bronze" classes. I don't actually know the number of classes nor their names as defined internally by Verizon, but customers are typically classified in several classes, and their traffic is treated differently. Maximum bandwidth is the first (obvious) difference, but not the only one. In general traffic from higher classes is typically forwarded faster in the routers (i.e., it employs higher-priority queues in the routers, suffering less delay and jitter due to congestion) and in case of congestion, packets from lower classes are typically discarded first.

It is obvious that 50 Mbps is far more than enough bandwidth for Netflix, but in any case there is a small difference between the available service levels (which, by the way, the rep from Verizon probably didn't even know).

Comment Distributed notification (Score 1) 159

So... I add a Canary to my site, and when I remove it, you launch an announcement in yours. Aren't we building together a distributed system which violates the explicit compulsory silence associated to the order? I mean, a canary is used because an explicit announcement is forbidden, so this system might constitute an explicit violation of the silence order, without the original user (the one who added the canary) even knowing. Is this correct? Are both parties liable?
