Check out 10 tips to improve the life of the computer

    Measures such as updating your software, keep up the signature of your antivirus and scan for spy programs (spyware) can increase the life of your appliance.



    Do not have money right now to buy a computer and need to postpone the exchange for a new one? So it is best to leave the maintenance of your device in the day , according to information from manufacturers . According to Microsoft , your computer and your car have something in common : they both need regular maintenance . Measures such as updating your software , keep up the signature of your antivirus and scan for spy programs ( spyware ) can increase the life of your appliance .

Check out 10 tips to keep your entire computer for longer :

1 - Put it in in a location with adequate

    According to Fernando Soares , manager of HP consumer , users should keep the computer in areas with adequate ventilation to avoid overheating of the machine . In general , computers tolerate a temperature up to 45 º C , but indoors and with poor ventilation , the temperature may be above this mark , compromising the product . " This high temperature will not cause immediate problems , but in the long run will cause additional wear to the unit ," he says .

2 - Clean the machine

    Like all items in a home, the computers must also undergo periodic cleaning to prevent the accumulation of dust that can compromise the life of the machine . " It's always good to clean to prevent the accumulation of dust, which is more common in fixed computers than laptops ," says Fernando . The fat of the user's skin also usually reach the machine and therefore the computer hygiene is necessary to prevent that dirt systems compromise the device.

3 - Update the software

    According to Microsoft , it is important that you sign up to receive software update notifications by email so acquires the computer . " Many software companies notify the customer by e - mail whenever a software update is available . This is particularly important for your operating system , your antivirus program and your firewall , "says the company .

    The company also states that it is important to register the software , because this is another way for the manufacturer to notify you when there are new updates available . The constant updating of the operating system prevents malicious software become lodged in the system and compromise safety and life of the computer .

4 - Be careful with the battery

    According to the manufacturer Lenovo , the first to properly recharge the battery is critical to the load is prolonged . " It ensures the accessory real recognition capacity energy storage . The recommendation is that the load inaugural netbooks and notebooks is 12-24 hours in the making , "says the manufacturer. Keep the battery cool and never leave the device with the battery in the car or in direct sunlight are also simple measures that avoid the temperature rise of the accessory and decreased functioning .

5 - Remove the temporary files

    "People think that the machine is getting slower over time because it has less memory to work , but if taken correctly the files that are not in use , greatly decreases the memory part compromised," says Soares . According to him , many times users install a program on your computer to use quickly and then just deletam the file , thinking that thus the memory will not be compromised. However , the ideal is to follow the manufacturer's guidelines when uninstalling software to ensure that the machine will be removed all files , main and secondary, were installed with the program .

    To avoid even some unused file remains on the computer taking up space is important that attention be periodically removed from the temporary files . " Delete files that are not used for a long time is a good way to keep free memory and faster machine ."

6 - Avoid falls

    The safe transportation of computers to minimize falls and shocks tends to maximize the lifetime of computers . " Especially in the case of laptops, users do not always carry your computer properly , often leave the machine fall on the ground and this lack of care compromises the device," says the manager of HP consumption .

7 - Back up your files

    Microsoft claims to backup ( backup ) of your files that can be used in case of loss of original by accidental deletion, data corruption , natural disasters , power loss, among other factors .

8 - Keep updated antivirus

    Microsoft recommends using the tool antivirus scan regularly for viruses and the like that may be present on the computer and therefore may compromise the behavior of the machine . In addition , you need to check the manual of your antivirus program if you can schedule an automatic scan .

9 - Change passwords frequently

    According to Microsoft , users should change passwords preferably monthly to reduce the risk of others accessing your computer . The company also recommends that the passwords are chosen carefully and be strong , you do not have predictable data such as name , date of birth , age . Passwords ideals have many characters , close to 12 , and must contain uppercase letters, lowercase letters, numbers and symbols .

10 - Make periodic maintenance


    Maintenance performed regularly , with markings on the agenda or calendar online and , if unable to meet the scheduled date, to be rescheduled. " Remember, you are not only helping to improve your computer but also to protect your personal information ," says Microsoft .

How to detect and troubleshoot computer software com seu not or Process Explorer

     If your machine "hangs" every now and then for no apparent reason, the first thing you think is on hardware issues, but often the answer lies in programs that misbehave and cause your machine to stop working should be. We'll teach you to easily detect these programs misbehaving.

     If all applications are closed, why is my PC fan suddenly began to make noise? The processor is at most, but I'm not doing anything with the machine.

How do you get to realize what is going on these occasions?

     At the heart of Windows there is a small piece of software called "System Scheduler". It is the most active part of the operating system and is the one that controls how programs can access the resources of your machine, such as RAM, disk or processor. The problem is that the task manager Windows can not access this area of ​​the operating system, so you must use a program that can get more information. This program is called Process Explorer, is supported by Microsoft and nothing escapes!

start

    Unlike other programs , Process Explorer does not require installation , so after you download it , if you give two clicks on the icon of the program you can just start using it . Or also can put on a USB key to take you wherever you want and use the computers you want. Since I have Windows .


    So you can see what the System Scheduler is to do at some point have to run Process Explorer with administrator rights . To do this click with the right mouse button on the program icon and select " Run as Administrator" from the context menu that appears . Then a window appears asking for confirmation of this action . Confirm .

    Next is the main interface of Process Explorer . Maximize the window to see as much information as possible .

    Click on " View" , " System Information " to see a window with all the information about the resource consumption of the machine .

   Also present are some tabs that show the status of various parts of the operating system and hardware . In systems with multicore processors should see a graph for each core .



Implementan una interfaz brain-computer to it conducción un automóvil robotic

     Pioneering research in Latin America that projects the implementation of a brain-computer interface in a car navigation completely automated , is the main goal of a collaboration between the Technical University Federico Santa Maria (Chile ) and the Federal University of Espírito Santo ( Brazil ) .

    This is the generation and implementation of a hybrid interface that combines the elements of autonomous navigation of a vehicle, with biological elements as EEG signals , thus furthering technological integration , linked to the mobility of persons with quadriplegia , paraplegia and motor disabilities in general. This through a BCI ( Brain- Computer Interface) .

    The investigation is being conducted by Drs . Teodiano Alberto Bastos de Souza Filho ( Brazil ) who, from the Universidade Federal do Espírito Santo , leading the areas of Information Technology and Bio Engineering, respectively. Meanwhile, the work of the Universidad Santa María in this investigation is led by Dr. Fernando Auat Cheein , Academic Department of Electronics, who heads the robotics area .

    How does this interface? Dr. Auat Cheein explains that " if you imagine that you are moving your right arm that is reflected in a part of the brain, which is the motor cortex, and if you make the movement will be reflected in your EEG signal . All that is known as potential obey different types of stimuli . What we are implementing is a brain-computer interface based on visual stimuli precisely . "

    These stimuli must not affect the vision of the person who is driving, so that "we need an autonomous vehicle that can react to a pedestrian who is crossing in front and to detect environmental conditions , such as location and traffic conditions, because as is intended to be used by people with special needs , you may not be able to react to a sudden change in the route , "the academic .


      The litmus test for this car robot will make a journey connecting the cities of Vitória and GUARAPARI , in the state of Espirito Santo ( Brazil ) . This is a trip of 50 miles to be completed this mobile in their manufacture is like any other vehicle but which meet certain features such as automatic , hybrid and later adapted to incorporate brain-computer interface .

    The respective teams have worked together to combine their experiences in the areas addressed by the project , so Brazilian experts have visited the USM , and the group of this squad has traveled to the Federal University of Espírito Santo , instances that have marked the progress of the investigation.

    " On our trip we go on some improvements to the algorithm of Simultaneous Localization and Mapping, artificial intelligence algorithm and recursive estimation , that what it does is locate and construct a map around the robot, at the same time. While in the area of ​​Bioengineering define deployment features of brain-computer interface for controlling the car , so it can be appropriate to command it , "said Dr. Fernando Auat Cheein .

    The primary objective is that the car walk alone , without human intervention , " it's already done , we must now integrate BCI , in order that it can address the car." Meanwhile, already finalized two visits by the research team in Brazil. Professor at the University of Espirito Santo , Edilson de Aguiar , and doctoral student of the University , Lucas Veronese , met with Dr. Auat Cheein at USM to process data , advancing aspects of the project that involve attaching the computer science and robotics area of land , plus new research project on the subject.

     In addition, Dr. Sandra Torres , a researcher at the Federal University of Espírito Santo , an expert in the field of brain signal processing , also visited the USM to work with Dr. Auat Cheein in the scope of the connection of the BCI ( Brain Computer -Interface ) with the car.

    "The goal of my work is that the use of this interface is more natural for the user and is seen as something very practical . There is a great debate in the field of brain-computer interfaces how to give momentum to be practical devices in everyday life . In that sense I do not think only people with disabilities but also to be used from the entertainment world , "says Dr. Sandra Torres.

     Dr. Auat Cheein emphasizes that they are aware that there is currently no regulation for a car of this kind, but " do not forget that this is a research project , not a product that is being developed to a commercial level " . The project involves a number of challenges in this area as well , " to cause an accident, who would be responsible ? " Says the academic .

     Once it is addressed technical work must be validated . In this case , experts warn that it is a challenge (which is expected to close in the short term) put a person in the car and traveling a path defined . " We've done preliminary tests tetraplegic and paraplegic persons , in order to measure the relationship between comfort and safety with the use of the interface. But are essential for qualitative research, " says Dr. Sandra Torres.

    "We need to evaluate how well that person clicked with the hardware and receive a feedback from you : if you liked , if you felt confident , that's very important. We do not want a person to control the car , but we want to complement "concludes Dr. Auat Cheein . ( Source : USM / DICYT )

Windows 9: what to expect from the new generation operating system?

   A list of resources that may be in Microsoft's plans and would like to see in the new Windows.


      In 2009 , we did an article commenting on some features that we would see in Windows 8 . The text had created humorous character , but not all of our guesses were unfounded .

     Now that Microsoft is moving at a fast pace ( with version 8.1 available now and a possible 8.2 in the oven ) , we can bring some realistic predictions for Windows 9 .

     We note that so far there is no concrete details on the timeline for the development of the next update , nor information about the release of the next Windows. We can not know if the developer will bet on annual updates to Windows 8 or if the plan is to revamp everything and release a new version .

     Thus, it is important to keep in mind that maybe some hints of this article did not end up coming true . Anyway , we are well acquainted with the latest rumors , so a sensible article that addresses certain features that really can appear in Windows 9 makes perfect sense at this point .

Rethinking the system

    As quoted in the analysis of Windows 8.1 , the current system of Microsoft is very indecisive. The product can not fully please neither environments to which it proposes to serve . Be in a tablet or a desktop computer , the software is weak with confusing features that arise as a result of dual visual .

   Due to the large drop in sales of desktop and convergence for devices with touch screen , we can not wonder if Microsoft decided to abandon the desktop interface system . This would be a good bet , but a rumor says otherwise .


      According to a posting on a Russian forum , Microsoft will bring the Aero interface (same as Windows 7 ) back in Windows 9 . The person who shared the information said that the old look will be reset to please users who complained about the new interface , however it is possible that the Aero is modified slightly .

    Anyway , bring the Aero interface back in the game does not mean much . It is essential in the new Windows, because many software have not yet migrated to the new visual style system - and to maintain compatibility with large applications is of paramount importance to Microsoft .

    A good idea would be to provide the power of choice to the user . Who uses a desktop PC or a notebook without touchscreen could make the whole system only in desktop mode , while tablet users would enjoy the modern interface .


     This is not a bad idea and see it happen with Apple products (which does not force users to use computer programs and the interface of iPad ) . Systems are different , so you need different functionality . Rethinking the system would certainly be the best idea to ensure the best user experience .

New Control Panel

    This overhaul the system would not only be in the interface , but in all resources . One of the problems pointed out in our analysis is precisely the poor organization of options and settings . With a Classic Control Panel and a few functions accessible through the new interface , people find themselves lost in various situations .

    Play options for a single location would be a major breakthrough , because the user does not need to scour hidden menus to find settings that are essential . In the case of a separation interface ( desktop computers and touch) , the panels could be arranged in the same way but with icons designed for each type of display.


     Something that disturbs a lot in Windows 8 is the lack of a system manager who is really active. Windows 9, we can expect this integration between items in the Control Panel (which may even include software settings) and the interface. Intelligent notifications could make the system more useful and simple.



Nexus 5 would not be as sweet without the "Kit Kat"

   Equipped with the latest Android version, device shows the best aspects of the system from Google. There is little reason not to consider him as a candidate for their next smartphone.

    Editor's Note : This is a review of the North American model of the Nexus 5 , written by our colleagues TechHive . We will do a new analysis of the smartphone when it is officially launched in the domestic market .

    The Nexus 5 picks what Google has to offer and the best place in a plastic bag and bland . He gives us the sweet nectar of pure Android , but the features in a generic housing that does not seem to be special . The smartphone is excellent and can easily compete on an equal footing against the Samsung Galaxy S4 , the Apple iPhone or the Nokia Lumia , but there are a few things here that have not seen before in other high-end smartphones . If not for the software , the Nexus 5 would be just another Android smartphone .

hardware mundane

    As someone who used an iPhone 5 over the last year , I have to say that using the Nexus 5 is like a breath of fresh air . The 4.95 -inch screen with full HD resolution (1920 x 1080 pixels ) is crystal clear , and leaves the 4-inch screen of the iPhone to shame . Text is crisp , eye popping colors and the image is visible even under direct sunlight .

     Only there's a catch : the screen is not very bright . In any brightness level than the maximum , the screen looks dark and dull . Enable automatic adjustment of brightness will help in battery life , but at the same time will make the impact of the screen .

    The device feels solid enough to survive a few tumbles height of pocket , but the design does not stand out compared to the HTC One or iPhone . Even the colorful Lumia has more personality, and the color scheme completely black ( or predominantly white) Nexus 5 makes it so indistinct as many other Android smartphones .


     The housing is made of plastic, and although she did not give the unit the appearance of something cheap, does not seem sophisticated. The buttons on / off and volume, made ​​of ceramic, rattle when you shake the smartphone, and the giant logo "nexus" stamped on the back looks tacky. The Nexus 5 does not collect fingerprints just like the iPhone and the Galaxy S4 5c do, but the rubberized finish attracts dust and crumbs, so be careful where you place the device.

    You also need to be careful with the camera lens Nexus 5, which protrudes slightly beyond the rear and prevents the device lies flat on a table. The lens is completely exposed, and I worry that it is the first thing to break if the smartphone decides to take a quick dip toward the sidewalk.


     The slim profile makes it easy to put the phone in your pocket and hold it with one hand , but had trouble reaching the power button without adjusting the grip . If the button was one or two millimeters lower I would not have to stretch your fingers to either wake up or switch off, and look what I have small hands .

    Using the Nexus 5 with one hand was a little difficult, since I could not reach both the notifications panel at the top of the screen and typing with one hand made ​​the unit look unbalanced.

Fast and good battery life

    Although the design of the Nexus 5 is modest , the hardware inside it is the same level as the other top of the line Android can offer . The quad-core processor Qualcomm Snapdragon 800 running at 2.26GHz is a monster , and coped smoothly with all threw in his way, HD video games like Dead Trigger 2 .

    The Nexus 4 was a very capable smartphone , but warmed only look bad for him . In Nexus 5 played Dead Trigger 2 for over an hour, watched the first half of Pacific Rim and the unit was only slightly warm . And most of the heat because it was held for so long .


    As the cameras of Nokia Lumia 920 and 1020, the 8 MP camera of the Nexus 5 has optical image stabilization (OIS). Even if you have steady hands, this feature will help you make better pictures under low light and avoid videos that appear to have been recorded in a boat at sea.

    The Nexus family of smartphones are not known for their photographic capabilities, but the Nexus 5 can produce very beautiful images. Under favorable conditions the image quality is equal to that seen in the iPhone 5 or 5s, but you will still have better low light performance with a One HTC or Nokia Lumia 1020. The "Photospheres", 360-degree panoramic photos are back, but there is a feature to save pictures in slow motion as the iPhone 5s, S4 Galaxy or HTC One.

    We still can not submit the Nexus 5 a round full battery tests in our lab , but I got about 7.5 hours of battery life on a single charge , so with Wi - Fi on , screen brightness to maximum and playing too . Your results may vary , but you should get a full day of use of the device . The battery is not removable , so if you want to increase the autonomy you have to use an external battery .

The secret is the software

     From the point of view of hardware a Nexus 5 is like a LG G2 with a new pack , battery with lower capacity and lower resolution camera . What makes the device , and the Nexus line usually so noteworthy is the software: 5 Nexus is the first device to run Android 4.4 " KitKat " , the latest version of the operating system from Google .

     Even if you are familiar with previous versions of Android, KitKat looks like a whole new world , and is the main reason to buy a Nexus 5 . Changes in the visual system to give a modern look and elegant , and features such as search and Google Now are in the foreground .

     If you felt jealous of voice commands in Moto X , will be happy to know that the KitKat has a similar feature that lets you edit searches from the home screen , just say " OK Google " . But it is not exactly the same thing , since the smartphone has to be awake and on the home screen , which means that the feature is not so useful when you are driving or hands occupied.

     The feature also allows you to give simple commands to the phone , so you can compose emails and text messages , but often need to tap on the screen to complete the task . And still can not use it to turn on or off Wi-Fi

     Several changes in KitKat seem to be part of Google 's effort to encourage people to adopt a social network , the Google+ . The most disconcerting of these changes involves removing the app Messages, replaced by Hangouts , which was previously known as Google Talk. Now the app has two functions , serving both for text messages ( SMS ) and instant messaging ( IM ) .

     Combining the two apps is something that makes sense , but the execution leaves something to be desired . When you start typing the name of a person to compose a new message , the results show not only the contacts in your phonebook , but also people on Google+ with the same name . Your contacts will be first on the list , but the recommendations Google+ will confuse people who just want to send a message to a friend , but now has to choose which of the five hundred people called " John " want to talk .

    The company, which is the first smartphone launched in August 2011, boasted on Twitter that sold 100 thousand. copies of his new device called MI3 in just 90 seconds.

    See AllThingsD points out that the company grew loud in August this year, when pulled together the leading manager of Google. Hugo Barra was responsible for the development of the Android operating system, and now works for a fast-growing young company in China. Xiaomi gadgets installed in your Google product

NTT system will have its own smartphones

Later this year, computer maker will begin selling its own phones.


     Fact NTT system follows in the footsteps of other manufacturers of modern electronics . After entering the tablet market , the company will want to also occur in the smartphone market . First phone - made in Chinese factories , but the logo near Warsaw company, will hit the shelves Polish stores later this year.

- In 2014, we will expand our offer with new models . We sell about 40 - 60 thousand . phones - says Tadeusz Kurek , President of NTT System.

    He added that the demand for smartphones will depend on two factors. The first of these is to increase the sale of these devices in the so-called . retail channel , or in traditional stores. If there is , telecom operators will be to introduce more and more cheap offers subscription without having to buy a phone with them .

    However, the second factor, which - according to the President of the Hen - can accelerate the demand for equipment is the development of data transmission in LTE . The spread will increase demand .

    NTT System also announced that on any day will offer its five new tablet models with a diagonal from seven to ten inches.

- We hope that this year will sell more than 50 thousand . tablet under its own brand - says Tadeusz cock .
