Salut! Tocmai am lansat prima versiunea din Stranded : Lost Island 2. Dupa multa pauza, m-am decis sa intru iar in dezvoltarea de jocuri mobile. In continueare puteti vedea si testa rezultatul. Multumesc! Imagini de prezentare: photo upload DOWNLOAD AND TEST IT! https://play.google.com/store/apps/details?id=com.vDesign.Stranded2 Atentie! Aceasta este prima versiune lansata a aplicatiei, ceea ce sugereaza faptul ca aplicatia este in continua dezvoltare. Nu criticati efectele slabe ale aplicatiei. Vor exista update-uri continuu... ENJOY !

WiFi jamming attacks more simple and cheaper than ever Posted on 13 October 2015. A security researcher has demonstrated that jamming WiFi, Bluetooth, and Zigbee networks is not difficult to perform but, most importantly, also not as costly as one might think. According to Mathy Vanhoef, a PhD student at KU Leuven (Belgium), it can easily be done by using a Wi-Fi $15 dongle bought off Amazon, a Raspberry Pi board, and an amplifier that will broaden the range of the attack to some 120 meters. The attack would hit all devices within range that operate in the 2.4 and 5 Ghz bands. With the above mentioned networks being crucial to the functioning of many IoT devices and systems - home security systems, car locks, baby monitors, and so on - it should be obvious that the fact that these attacks can be performed so easily and cheaply may lead to serious consequences. In fact, it is known that cheap jammers are already being used by crooks around the world: That's why it's crucial that defenders are able to detect these attacks when they are going on, even if they can't stop them. During his recent presentation at BruCON, Vanhoef explained that by modifying the dongle's firmware he was able to force the target networks to always give priority to the device's transmissions. If the device is made to transmit continuously, it means that all other devices won't be able to, making the channel effectively unusable. His attempts at selective jamming (blocking specific packets) have been less successful, and he concluded that 100% reliable selective jamming is not possible. He also says that these low-level jamming attacks could influence attacks on higher level protocols. For example, he says that they can be used to mount a channel-based MiTM attack against WPA's Temporal Key Integrity Protocol (TKIP), which is still widely used. For those interested in more details, here's a video recording of Vanhoef's talk: Sursa: WiFi jamming attacks more simple and cheaper than ever

La primul punct ai repetat acelasi idee pe care am zis-o eu. La al doilea punct iarasi ai niste greseli Ai luat suma de 99.000 ca neavand TVA Ai luat suma de 99.0000 ca avand TVA Deci nu te-a interesat faptul ca cel care iti plateste ti-e factura de colocare care are inclus TVA-ul in cei 99000 va avea de platit 99.000 minus TVA-ul care si-l recupreaza, astfel platind faptic doar 82500 pentru pentru serviciul prestat de tine. Cele doua situatii date de tine nu sunt identice pentru cumparator si nici pentru tine, a doua este mai ieftina cu 20% fata de prima, de aceea tie iti da fix invers. Caculul ar fi in felul urmator daca ambele facturi ar avea valorea de 99000 fara TVA (nu si in cazul tau): 8250-1660 = 6590 Platitor de TVA 8250-2000 = 6290 Neplatitor de TVA *Sume lunare fara TVA Dupa cum am zis si anterior singura diferenta ii ca la neplatitor TVA-ul il suporti tu. O ultima observatie ar fi faptul ca nu sti sa caculezi TVA-ul. NU SE FACE ASA: 2000*0.2=400 de euro TVA-ul, CI ASA: 2000-(2000/1.2)=333 euro TVA-ul. Daca nu crezi incearca aici. Cred ca cu asta am terminat lectia de economie pe anu asta de pe RST.
