Nekad je ovo bila naučna fantastika. Poslednjih dana je ponovo aktuelno. Ima više projekata koji se planiraju na tu temu, a ovi su mi najzanimljiviji : 1. Facebook eyes up solar-powered drones, to blanket the world with internet access Facebook, with the thinly veiled veneer of “bringing internet access to the underconnected,” is looking to acquire Titan Aerospace — an American maker of high-altitude UAVs (drones). The idea is that these Titan drones would be used to connect the 5 billion or so people who don’t yet have reliable internet access — a philanthropic act on the face of it, but when you consider that Facebook’s entire business model is predicated on continued growth, and that almost everyone in the world with an internet connection already has a Facebook account, you can see that this is more about self-preservation than humanitarianism. Titan Aerospace has two products, the Solara 50 and Solara 60, which the company refers to as “atmospheric satellites.” They seem to be functionally identical, except the Solara 60 can carry a larger payload. Both aircraft are powered by a large number of solar cells, allowing them to ascend to 65,000 feet (almost 20 kilometers), and then circle over a specific region for up to five years (presumably that’s the lifetime of the on-board lithium-ion batteries, which are required for night-time operation). The high altitude is important: The FAA only regulates airspace up to 60,000 feet — above that, pretty much anything goes. Once these atmospheric satellites are up there, there’s a wide range of possible applications. Facebook is obviously interested in internet connectivity, but mapping, meteorology, global positioning, rapid response to disasters and wildfires, and a whole slew of other scientific and military applications are also possible. (Read: Facebook creates Internet.org alliance to reduce price of mobile data plans to 1% of current price.) As for what level of connectivity Facebook hopes to provide with these drones, it’s too early to say. TechCrunch reports that Facebook, which is looking to acquire Titan for $60 million, would launch 11,000 Solara 60 drones. Their coverage would begin with Africa, and then spread out from there. There’s no word on how fast these connections might be, nor how much such a connection would cost the end user. Perhaps more importantly, there’s also no word on how Facebook intends to connect these 11,000 satellites to the internet. Facebook will need to build a lot of ground stations, perhaps in very remote and very hard to administer areas, and then run fiber to hook them up to the internet. And yes, in case you were wondering, this effort appears to be very similar to Google’s Project Loon — which is essentially the same thing, but using big balloons instead of winged aircraft. It’s worth pointing out that Titan hasn’t yet produced a commercial UAV. “Technology demonstrations” have been flown (probably much smaller prototypes), and “initial commercial operations” will start sometime in 2015. Perhaps this is why Facebook is only paying $60 million for Titan, rather than the $19 billion it paid for WhatsApp. While bringing internet access to the underconnected masses is really quite a noble undertaking, don’t ever mistake this for an altruistic act. One of Facebook’s most pressing problems is how to grow its user base. Almost everyone who has an internet connection already has a Facebook account (or uses one of its national competitors, like Russia’s VKontakte). If Facebook doesn’t continue to grow, and doesn’t miraculously stumble across some way to make more money (its ads aren’t doing very well), the stock market will react very poorly indeed. Facebook is almost a victim of its own success — it got so big so quickly that it’s virtually impossible to continue the same growth trajectory. Acquiring Instagram and WhatsApp were a savvy moves to bring in a few hundred million more users, but ultimately they were nothing more than stopgap measures. Bringing the next billion users online and into Facebook’s gribbly mandibles will be a very hard task indeed. http://www.youtube.com/watch?v=AIBxou0STfY Videti: http://www.extremetech.com/extreme/177922-facebook-eyes-up-solar-powered-drones-to-blanket-the-world-with-internet-access 2. OUTERNET https://www.outernet.is/ 3. Google Loon Balloon-powered Internet for everyone http://www.google.com/loon/ Postavlja se pitanje , šta će da rade ovi naši internet monopolisti kada 2015 počne globalni provajder da radi preko dronova , i svako bude mogao da koristi za džabe Wi-Fi i/ili GPRS besplatno. ? Recimo poreska uprava zabranjuje zakonom i stalno ganja provajdere za pristup stranim sajtovima koji priređuju igre na sreću preko interneta. Ukinuće nam (zakonom) svima Wi-Fi i/ili GPRS ? Blokiraće nam i ometati signal ? http://www.ratel.rs/...article_id=1469 Pravilnik se odnosi (ne samo na provajdere nego na sve koji koriste slobodne frekvencije) na sve i na CB i na wireles i na telekomande i na pejsmejkere... pošto nigde nije navedena minimalna snaga.

ubacio sam OPA2134 na snajperku+ Audio Noise Guard To help protect and insulate the the Realtek ALC898 audio processor and onboard amplifiers from electrostatic interference (ESD), the GIGABYTE G1.Sniper A88X motherboard features an audio noise guard that essentially separates the board’s sensitive analog audio components from potential ESD pollution at the PCB level. LED trace path lighting illuminates to show the separation of the PCB layers. + i ima Nichicon Gold elektrolite fabricke + odvojen USB DAC-UP port (prikljucak za odvojeno napajanje) to nema nijedna kartica koju ja imam

OPA2134 su kod mene i veci elektroliti. pogledaj prvu stranu ovog topica.ako menjas elektrolite ne preteruj sa velicinom kapaciteta. meni sjajno tako svira. ima i boljih kartica. imam i ESI MAYA 44 jos u kolekciji.no "snajperka" svira bolje

inace bolje svira ova "snajperka" maticna ploca (sa promenjenim OP-AMP-om = ima fabricko podnozje) od bilo koje kartice koju imam: http://www.gigabyte.com/products/product-page.aspx?pid=4683#ov znaci, neverovatno nesto

svi su isti. imam istu karticu.
