Statisticians Uncover What Makes For a Stable Marriage

fabrica64 A demonstration big data analysis may be worthless (447 comments)

That's a demonstration of how big data analysis may be worthless and misleading. Nowadays we don't talk about neural networks anymore but they mainly produced these kind of idiot results

DARPA Delving Into the Black Art of Super Secure Software Obfuscation

fabrica64 Re:Good luck with that. (124 comments)

So you can basically "mathematically" obfuscate a function that is a"pure" function not implementable in a imperative programming and that it has no IO = you can obfuscate something that has no use and probably nobody knows well what it is doing :-)

Apple Refutes Report On iPhone Threat To China's National Security

fabrica64 No security through obscurity (134 comments)

Software must be audited to be sure there's no backdoor... Only open source is secure (including open source silicon) If I were NSA I had built a backdoor in hardware, much more effective and software independent

The Lovelace Test Is Better Than the Turing Test At Detecting AI

fabrica64 Re:Turing test not passed. (285 comments)

I guess it can be described differently. As computers are deterministic, true AI is when a computer behaves in a not deterministic manner. Actually no computer has intelligence because given the same input, they give the same results.

Brazil Blocks Foreign Mobile Phones

fabrica64 Re:Not in june, only after september (97 comments)

The system works this way:
- there is a blacklist of TAC (initial part of IMEI that identify manufacturer, model and sub model: http://en.wikipedia.org/wiki/T... [wikipedia.org])
- actually info for this blacklist is furnished by manufacturers, that will probably include all their models regardless of being or not sold in Brazil, but this can be later changed by Anatel, restricting the list
- there will be a whitelist of "blacklisted IMEIs" activated in the network before March 17th, 2014
- there will be a blacklist of permitted IMEI (e.g. an iPhone sold in Brazil) that were used (i.e. cloned) in "IMEI configurable" Chinese smartphones/tablet
- there will be a whitelist of IMEI+IMSI to identify the original cloned (I don't know who will identify the original one if many claims to be the original one)
- block will be set in the network on each individual IMEI
- permission will be set in the network for specific IMEI+IMSI
- the system is tailored to control individual IMEIs and not only generic TAC
Do you see the potential of chaos? Chinese smartphone seller will setup "change your IMEI daily" services and it will be cat and mouse play until a complete mess... and mobile operator will hardly divert resource to help in solving it or handle complaints...

Brazil Blocks Foreign Mobile Phones

fabrica64 Re:Not in june, only after september (97 comments)

Probably yes (initial IMEI list will be provided by manufacturers) but once you have this system in place the government might use it more effectively to control and block smartphones not sold in Brazil. Why do you need such a system? Mobile operators hate it (if you pay you are ok), Anatel (the Brazilian FCC) approves GSM standards and most of smartphones abide to these standards, there's no technical reason here. The system can control individual IMEIs and it will also be used to control stolen devices

Brazil Blocks Foreign Mobile Phones

fabrica64 Re:Not in june, only after september (97 comments)

It was about to start blocking in April, but someone in the government got a ping from someone else about being very bad news blocking phones during the world cup... But it's not certain it will begin in September or if will ever start blocking, given all mobile operators are against this "system" BTW this is not only about Chinese smartphone (where you can change IMEI in a snap), it is about blocking smartphones not sold in Brazil (although nobody will ever admit it in the government). IMEI can differentiate between an A1457 sold in Brazil and one sold in Europe, and HTC is not sold at all here I mean, it may appear to be an article for cheap country based hate but actually is Brazilian government that expose himself to the ridicule sustaining something being done for technical reasons when in reality is a pure fiscal issue.

Interview: Ask Eric Raymond What You Will

fabrica64 Shared consensus (126 comments)

What do you think about shared consensus technology (i.e. bitcoin)? Are they the bazaar while centralized entities (like the Fed) are the cathedrals? Do you think these technologies can be used in other areas in addition to bitcoin and play an important role in the future Internet?

Linus Torvalds Admits He's Been Asked To Insert Backdoor Into Linux

Why bother asking Linus to put a backdoor in Linux when it's just easier to ask Intel putting a backdoor in their processors?

France Considers 'Pirate Tax' For Online Ads

fabrica64 Who gets the tax money? (271 comments)

How would they know which artist is "pirated" and how to calculate the share of the tax money for each "pirated" artist? In Italy we have such a tax on CD and DVD, and guess who gets the money? Certainly not the artists...

You may not know it but many prosecutors here in Italy are well known for being quite stupid and just trying to appear on newspapers. Laws in Italy are sometimes so complicated that they can justify any kind of "crime"

Bitcoin: earn money on emerging market BTC rate spread

fabrica64 fabrica64 writes  |  about 3 months ago

fabrica64 (791212) writes "If you are an EU national residing in Brazil you can, theoretically, earn on Brazilian inflated BTC rates at biggest local exchange (www.mercadobitcoin.com.br)
Local BTC exchange is trading BTC with a 13% premium over BTC-EUR rate, so, for example, if I have 1 bitcoin I can trade it for 1473 Reals (BRL) and then trade 1473 Reals for 489 Euro (at 3.011 rate) and buy 1.132 BTC at current rates on BTC-e (July 30, 2014, 19:19 UTC) with a 13+% gain
Transferring Reals to Euro, if you are a legal resident in Brazil, will cost you no more than 4%, and even paying another 4% for additional fees you end up with 5% gain...
I guess the same is valid for USD.
Has anyone ever tried that?"

Brazil blocks foreign mobile phones

fabrica64 fabrica64 writes  |  about 7 months ago

fabrica64 (791212) writes "Brazilian government starts today blocking mobile phones not sold in Brazil, i.e. not having paid sales taxes here.
The blocking is based on IMEI and if you come to Brazil for the world cup in june and think of buying a Brazilian SIM card to call locally at lower rates then it won't work because your mobile's IMEI will be blacklisted as not sold in Brazil.
This is not a joke, its true!"
