Change the Default Administrator Password on Wireless Access Points and Routers

Change the Default Administrator Password on Wireless Access Points and Routers

Nearly all wireless access points and routers allow an administrator to manage their WiFi network through a special administrative account. This account provides complete "superuser" access to the device's configuration utilities with a special username and password.
Manufacturers set both the account username and password at the factory. The username is often simply the word admin or administrator. The password is typically empty (blank), the words "admin," "public," or "password," or some other simple word.

To improve the security of a Wi-Fi network, you should change the administrative password on your wireless access point or router immediately when installing the unit. The default passwords for popular models of wireless network gear are well-known to hackers and often posted on the Internet. Most devices do not allow the administrative username to be changed, but if yours does, seriously consider changing this name as well.

Finally, to maintain home network security in the future, continue changing this administrative password regularly, not just one time. Many experts recommend changing passwords every 30 to 90 days. Use words that would be very difficult for others to guess.

Facebook For Android Goes Native, Ditches HTML5 Code

Leave a Comment
Facebook For Android Goes Native, Ditches HTML 5 Code

Facebook has just released an update to their mobile app for Android devices which you could download right now over at Google Play. Instead of the usual HTML5 version this new version uses native code which promises to be twice as fast when launching and opening your Timeline.

The release of Facebook for Android 2.0 comes just days after the company launched a campaign by placing posters in their work areas encouraging employees to dump their iPhones and instead switch to Android. This also comes 4 months after the August update for the IOS version also doubled its speed.

This new app has been in development over the year and several key issues were addressed to make improvements.

Reducing Garbage Collection

Inefficient handling of memory can often lead to lag or freezing of the app. The team was able to solve this by deferring performing allocation-heavy code until the user stopped scrolling. “Inefficient memory usage will result in many garbage collection events, which in turn can pause the application for multiple frames and cause visible stutter during scrolling.”

 Writing a Custom Event Bus

Event buses allow communication between different classes and the old one was pretty slow. This new custom event bus is lightweight and avoids all reflection and object iterators.

Moving Photos to the Native Heap

Loading photos can be one of the most memory intensive activities for a device. Previously this was loaded to the Java heap which often times resulted in out of memory errors. This time the team made photos load directly to the Native heap.

Writing a Custom ListView Recycler

The original ListView recycler was inefficient when it came to handling elements of varying row heights such as news feeds. The team had to create a custom view recycler to correct this.

If you have already updated your Facebook for Android app you won’t see any changes in the UI at all. What has been improved is all under the hood and will be immediately noticeable once you use the app.

ATV docks with ISS

ATV Docks With ISS

The European Space Agency periodically sends an Automated Transfer Vehicle to the International Space Station to reload the astronauts with supplies. On March 28, ATV-3, named Edoardo Amaldi, docked with the ISS. Astronauts on the station took this unbelievable picture of it as it approached: Wow. You can see the thrusters on the ATV burning to control its approach, like it’s right out of Star Trek! The stars, the green and brown aerosol layer over the Earth’s limb, the city lights slightly blurred from the ISS velocity of 8 km/sec – it gives such an eerie and unearthly feel to the picture!

As, I suppose, it should.

The ATV is amazing: this uncrewed machine can dock with the ISS using just GPS and star trackers — telescopes that can determine position and orientation by watching the stars… like ancient mariners did. [Update/correction: The ATV doesn't dock with ISS using just GPS and star trackers; it makes its approach using those. Once it's close enough, a more sophisticated laser guidance system is used.] This mission carried oxygen, water, hardware, spare parts, food, and even clothing for the astronauts.

While it’s docked, it may also be used as a booster, gently pushing the station into a new orbit to avoid space junk, or to boost the orbit higher. Although there’s almost no air up there, there’s some. Over time, as the ISS plows through these rarefied molecules, it loses orbital energy and drops into a lower orbit. Periodic reboosts are necessary, and the ATV can be used for the job.

The ATV can stay docked for up to six months or so. After that, it undocks, de-orbits, and burns up in Earth’s atmosphere, making a spectacular fireball. A blaze of glory, you might say, for a machine that helps keep humans in space.

Volcano Has Been Active in 36 Years

In late November 2012, Tolbachik Volcano on Russia’s Kamchatka Peninsula began erupting, the first time the volcano has been active in 36 years, according to Denison University volcanologist Erik Klemetti. Several days later, the volcano remained restless. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured two views of Tolbachik on December 1, 2012.
The top image is natural-color and shows what our eyes would see from the sky; the bottom image is made from a combination of visible and infrared light. Both images show volcanic plumes and a lava flow. In the bottom image, parts of the lava flow glow bright red, an indication of high surface temperatures. Gaps in the volcanic plumes allow glimpses of the lava flow underneath.
Klemetti reported that the eruption in late November occurred along two fissures. In these images, volcanic plumes—likely a combination of ash, water vapor, and other gases—apparently emerge from an east-west crack on the volcano surface. South of the plumes and the lava flow, multiple volcanic cones litter the surface of Tolbachik, casting shadows to the north in the low-angled sunlight.
Tolbachik is a shield volcano—a low-profile, broad structure with a shape resembling an ancient warrior shield. The volcano has a complex configuration, and the eruptive activity in late November reportedly occurred around the southern cone.

Relationship of job characteristics to job involvement, satisfaction, and intrinsic motivation.


Findings of the research articles on the topic “Relationship between organizational attitude and behavior (job satisfaction, job involvement and organization commitment) and work motivation.

Relationship of job characteristics to job involvement, satisfaction, and intrinsic motivation.
Administered questionnaires to 291 scientists working in research and development laboratories. Results of a factor analysis indicate that job-involvement attitudes, higher order need-satisfaction attitudes, and intrinsic-motivation attitudes should be thought of as separate and distinct kinds of attitudes toward a job. These 3 types of attitudes related differentially to job design factors and to job behavior. Satisfaction proved to be related to such job characteristics as the amount of control the job allowed the holder and the degree to which it is seen to be relevant to the holder's valued abilities. Satisfaction was not related to either self-rated effort or performance. Job involvement, like satisfaction, bore a significant relationship to certain job characteristics; unlike satisfaction, however, involvement was positively related to self-rated effort. Intrinsic motivation was less strongly related to the job characteristics measured, but was more strongly related to both effort and performance than was either satisfaction or involvement. 
Intermediate linkages in the relationship between job satisfaction and employee turnover.
The relationship between job satisfaction and turnover is significant and consistent, but not particularly strong.
Organizational commitment, job satisfaction, and turnover among psychiatric technicians.
Studied changes across time in measures of organizational commitment and job satisfaction as each related to subsequent turnover among 60 recently employed psychiatric technician trainees. A longitudinal study across a 101/2-mo period was conducted, with attitude measures (Organizational Commitment Questionnaire and Job Descriptive Index) collected at 4 points in time. Results of a discriminant analysis indicate that significant relationships existed between certain attitudes held by employees and turnover. Relationships between attitudes and turnover were found in the last 2 time periods only, suggesting that such relationships are strongest at points in time closest to when an individual leaves the organization. Organizational commitment discriminated better between stayers and leavers than did the various components of job satisfaction.

Work Motivation and Performance: A Social Identity Perspective

Work motivation and performance were analysed from the perspective of social identity theory and self-categorisation theory. Central in this analysis is the relation of organisational identification with the motivation to exert effort on behalf of the collective. A theoretical analysis as well as a review of empirical studies of the relationship of organisational identification with motivation and performance leads to the conclusion that identification is positively related to work motivation, task performance, and contextual performance to the extent that (a) social identity is salient, and (b) high performance is perceived to be in the group’s or organisation’s interest.
Are Employee Motivation, Commitment and Job Involvement Inter-related: Evidence from Banking Sector of Pakistan.
Well motivated and committed employees with high levels of  job  involvement are considered to be the most important asset for any organization which serves as key to quality and productivity improvements. The current research study attempts to find the association among three important job related behavior of employees i.e. motivation, commitment and job involvement. Present study was conducted in banking sector of Pakistan. 400 banking personnel were randomly selected and responses were sought out from them by means of questionnaire. Out of total 400 distributed questionnaires, 305 were received back and 285 were considered as valid and then analyzed using SPSS 16. A significant but somewhat weak positive relationship of motivation, commitment and job involvement was found with each other.  Some important implications for future research are also derived from the study.

The relationship between employee motivation and job involvement.
The study aims to assess the current level of, and relationship between, employee motivation and job involvement.  This cross-sectional study was undertaken in a financial institution from which 145 employees were drawn using a simple random sampling technique. Data was collected using the Employee Motivation Questionnaire (Fourie, 1989) and the Job Involvement Questionnaire (Lodahl and Kejner, 1965) and, was analysed using descriptive and inferential statistics.  The results indicate that significant intercorrelations exist amongst the majority of dimensions and sub-dimensions of employee motivation and job involvement.

Job motivation and organizational commitment among the health professionals: A questionnaire survey
The objective of this study is to investigate the level of organizational commitment and motivation as well as the relationship between health staff’s organizational commitment and motivation within state hospitals. Using the Structural Equation Modeling (SEM), the relationships between the organizational commitment and motivation were examined. Data for this study were obtained through a questionnaire. The questionnaire was applied to health professionals working in state hospitals by using the “Organizational Commitment Questionnaire” and the “Motivation Questionnaire”. Within this scope, the organizational commitment levels of the health professionals were analyzed in three dimensions which are emotional commitment, continuance commitment and normative commitment and the motivation levels of the health professionals were examined in two dimensions: intrinsic and extrinsic motivation. The results indicated that intrinsic motivation of health professionals was explained mostly by affective and normative commitment. Also affective and normative commitment impact on intrinsic motivation was more than continuance commitment. The most effective factor on extrinsic motivation was normative commitment. Continuance commitment had effect on extrinsic motivation less than normative commitment. Also it was seen that the affective commitment had the lowest effect on external motivation.
