The Secret Life Of Walter Mitty PrintableReview: I do not give ratings 10 easily, but here it is - the first film in this year that was earned rating.Neill Blomkamp brings to the screen a wonderful, gritty, realistic piece of science fiction with the District number 9 Ever since Ridley Scott's Blade Runner, John Carpenter's Thing, or James Cameron's Aliens, we have seen a science fiction film with a vision of this caliber. Seeing District number 9, it will be clear to everyone, why Peter Jackson put so much faith in Blomkamp and took him under his wing as a prot? Leaving normal settings Hollywood science fiction and put us in a harsh slums of South Africa, we have the original piece of work that takes risks in the way he tells his story. This is not only contrary to the expectations of the public, who have been trained to expect mediocrity of his science fiction, it goes beyond the call of duty to provide us with the spectacle and something to think about after Weve brought down our popcorn.There is, fortunately, not too much overexposed celebrity in sight, and every unknown person in the film gives good results. Aliens themselves, brilliantly realized with high quality CGI even manages to make us feel something, just to compete with Gollum from Lord Rings.District 9 has so much wanted.

But well-written bug reports can decrease the time between finding a bug and resolving it. Bugs can delay an app’s release, and problems with bugs can quickly spoil relationships with clients. Today we’ll describe what a quality bug report should look like so you can avoid unnecessary delays in bug resolution and avoid strained client relations during your project development process. Let’s compare a poor bug report with a good bug report What does a poor bug report look like? Sample Bug ReportTo understand how to write a quality bug report, let’s first look at how to write a poor one. Imagine we’re working on a social networking website that connects football fans in group chats. After an update rolls out, a QA specialist fills out a bug report in JIRA. Let’s take a close look at this report: At first glance, everything seems fine with this bug report, doesn’t it? We have a description, a summary, and some other details related to the issue. What’s lacking? Conflict with disc emulator software detected fixie bikes. Let's dive deeper. ![]() Bug ID: JIRA gives an ID to the bug automatically, so we see nothing wrong here. Bug Summary: This information is located below the ID. The summary of this bug isn’t specific. There are various types of users, and this summary doesn’t specify for which user(s) the bug occurs. A developer working on this issue will have to ask additional questions to clarify. Bug Details: The tester didn't provide any data about the application version and testing environment. Software Test Report Example![]() We will talk through these details further in the article. As for the priority, testers usually assign a priority level, which may change later. Bug Description: This section raises the most questions. Here, the tester should explain Steps to Reproduce, Actual Results, and Expected Results. A bug report should give as much relevant information as possible. ![]() Bug Report Template In Software TestingIf your QA representatives don't describe how to reproduce a bug thoroughly enough, then developers will waste time trying to figure out what’s wrong. After reading the description in our screenshot, web developers will immediately ask what login credentials were used: admin, test user, or moderator. Also, they’ll need to know the server (environment) on which the bug was produced. In other words, did this happen on a testing server, for example or a production server, for example The tester should also have provided Expected results. These details help a developer — who may not be very familiar with the app — understand the issue faster. Finally, we don’t see any visual documentation of this bug, such as attached images.

In what could possibly be one of the most infectious and upbeat team-up albums in pop-punk history, combine forces with tourmates and on. Looking to mix things up, the three-way split features each band playing the songs of the other two, creating a pop-punk musical chairs that feels like a whole summertime of love, heartache, and partying packed into one album. As an added bonus, also features a new song from each band, and as an added added bonus, the album also features an extra song by 's and ', 'Love Ya, Love Ya, Love Ya.' For fans of any of these bands, or really of fun in general, is a no brainer of a purchase. Bowling for Soup’s 12 th album doesn’t mess with their formula of hooky, snotty yet sincere pop-punk too much, but it also introduces pumps up their songwriting. Their song “Let’s Go to the Pub” has the same kind of insistent radio riff and nasal vocal about girls who just don’t understand as their previous hits like “Girl All the Bad Guys Want,” a rallying cry to slam jager shots with the boys and forget about girl troubles. While that’s universal and eternal enough a theme and sound, Bowling for Soup acknowledge their ’70s rock nerd core on songs like “My Heart Explodes,” an unexpectedly straightfaced love song with a “la la love me” refrain that would make the Ric Ocasek proud. “Spin Me Around” similarly makes for a heartfelt, lovably cheesy love song about enduring love with a Kansas-style vocal harmony coming out of nowhere at the end. Sometimes pop-punkers grow up and their sound doesn’t have to grow tired in the process. ![]() Rise Of A King Hacked![]() Kingdom Rush Frontiers: Rise of Heroes with cheats: Keyhack [6] toggle unlimited cash.

Securing underwater wireless communication networks ppt.pptx123.pptx. Underwater Wireless. The unique characteristics of the underwater acoustic channel and the differences between such networks and their ground based counterparts require the development of efficient and reliable security mechanisms. The aquatic environment is particularly vulnerable to malicious attacks due to the high bit error rates, large and variable propagation delay, low bandwidth of acoustic channels in water. Achieving reliable inter vehicle and sensor-AUV communication is especially difficult due to the mobility of AUVs and the movement of sensors with water currents. The above mentioned characteristics of UWCNs have several security issues associated like packet errors, eavesdropping, modification of packets, and many more. Also since power consumption in underwater communications is higher than in terrestrial radio communications energy exhaustion attacks can reduce network life. The different attacks possible are Jamming, Wormholes, Selective Forwarding, Sybil Attacks, etc. ![]() Defences for these are discussed. Jamming can be overcome by Spread Spectrum techniques, Wormhole detection is done with a visual modelling using Dis-VoW and other attacks can be countered by authentication, verification, and positioning. Open research challenges for secure localization, routing and time synchronization are mentioned. In this paper UWCNs is discussed, with emphasis on the possible attacks, countermeasures and further opportunities and scope for development in this direction to improve security of such networks. Overview of Underwater Wireless Communication Networks Underwater wireless communication networks (UWCNs) consist of sensors and autonomous underwater vehicles (AUVs) that interact, coordinate and share information with each other to carry out sensing and monitoring functions. A pictorial representation is shown below: In last several years, underwater communication network (UWCN) has found an increasing use in a widespread range of applications, such as coastal surveillance systems, environmental research, autonomous underwater vehicle (AUV) operation, oil-rig maintenance, collection of data for water monitoring, linking submarines to land, to name a few. By deploying a distributed and scalable sensor network in a 3-dimensional underwater space, each underwater sensor can monitor and detect environmental parameters and events locally. Hence, compared with remote sensing, UWCNs provide a better sensing and surveillance technology to acquire better data to understand the spatial and temporal complexities of underwater environments. Present underwater communication systems involve the transmission of information in the form of sound, electromagnetic (EM), or optical waves. Each of these techniques has advantages and limitations. Based on applications there are three types of UWSNs (sensor networks): 1) Mobile UWSNs for long-term non-time critical applications (M-LT-UWSNs); 2) Static UWSNs for long-term non-time critical applications (S-LT-UWSNs); 3) Mobile UWSNs for short-term time-critical applications (M-ST-UWSNs). Besides the UWSNs mentioned above, underwater networks also include sparse mobile AUV (autonomous underwater vehicle) or UUV (unmanned underwater vehicle) networks, where vehicles/nodes can be spaced out by several kilometres. These types of networks have their unique communication requirements. Among the three types of waves, acoustic waves are used as the primary carrier for underwater wireless communication systems due to the relatively low absorption in underwater environments. The security requirements to be met in UWCNs are: • Authentication: Authentication is the proof that the data received was sent by a legitimate sender. This is essential in military and safety-critical applications of UWCNs. • Confidentiality: Confidentiality means that information is not accessible to unauthorized third parties. It needs to be guaranteed in critical applications such as maritime surveillance. ![]() • Integrity: It ensures that information has not been altered by any adversary. Many underwater sensor applications for environmental preservation, such as water quality monitoring, rely on the integrity of information. Availability: The data should be available when needed by an authorized user. Lack of availability due to denial-of-service attacks would especially affect time-critical aquatic exploration applications such as prediction of seaquakes. Some common terminology used here is defined: • Attack: Attempt to gain unauthorized access to a service, resource, or information, or the attempt to compromise integrity, availability, or confidentiality. • Attacker, Intruder, Adversary: The originator of an attack. • Vulnerability: Weakness in system security design, implementation, or limitations that could be exploited. Top Cellular Networks• Threat: Any circumstance or event (such as the existence of an attacker and vulnerabilities) with the potential to adversely impact a system through a security breach. Defence: An idea or system or model that counters an attack Jamming and Spread Spectrum Technique to Counter Jamming Jamming is deliberate interference with radio reception to deny the target's use of a communication channel. For single-frequency networks, it is simple and effective, rendering the jammed node unable to communicate or coordinate with others in the network. A jamming attack consists of interfering with the physical channel by putting up carriers on the frequencies used by nodes to communicate. Since it requires a lot of energy, attackers usually attack in sporadic bursts. Since underwater acoustic frequency bands are narrow (from a few to hundreds of kilohertz), UWCNs are vulnerable to narrowband jamming. Localization is affected by the replay attack when the attacker jams the communication between a sender and a receiver, and later replays the same message with stale information (an incorrect reference) posing as the sender. In frequency hopping, a device transmits a signal on a frequency for a short period of time, changes to a different frequency and repeats. The transmitter and receiver must be coordinated. Direct-sequence spreads the signal over a wide band, using a pseudo-random bit stream. Republic Wireless Cellular NetworkFrequency-hopping schemes are somewhat resistant to interference from an attacker who does not know the hopping sequence. However, the attacker may be able to jam a wide band of the spectrum, or even follow the hopping sequence by scanning for the next transmission and quickly tuning the transmitter. References 1.
