Google’s VirusTotal has begun running Mac apps in  Sandpit  environments to test for malware and malicious activity. The move has come not a moment too soon for many Apple users. Malware, and especially adware is at an all-time high. A report released in October by  Bit9,  claimed that more malware had been discovered on Apple operating systems in 2015, than had been found in the previous five years in total. Enter VirusTotal VirusTotal, owned by Google, is an online virus scanner. It is popular with both everyday users, and industry professionals, and is free to use. The  VirusTotal website  allows users to upload suspicious files and have them be scanned by 54 different antivirus products. Big Names Among the antivirus scanners utilized are some big industry names, including: Avast Avira ESET Panda McAfee Having the ability to scan any file you deem ‘dodgy’ by 54 of the world’s leading anti-malware companies is reassuring to mos...

The German Federal government has  approved  the use of a “federal Trojan” for investigative purposes by state intelligence and security agencies, according to an announcement made by a spokesman for the German interior ministry. The news was announced on Monday that the usage of Trojans had been authorized to monitor suspected citizens, and it could be put to use as early as this week. According to the Federal Data Protection Commissioner,  Andrea Vosshof f, testing of the software has already been completed and will be used to follow and monitor the actions and movements of suspected criminal and terrorist groups and individuals. Trojan software?  Isn’t that supposed to be bad news? Yes, it is normally. I suppose it’s approval by the  Interior Ministry  can either be viewed as a reasonable common sense law enforcement initiative, or a Big Brother like overreach encroachment into the everyday lives of German citizens. Whatever your viewpoin...

With varying news reports swirling across the internet, it’s hard to get a full grasp on the now-infamous locked iPhone case. Some reports have indicated that the FBI is the one that  accidentally locked  the San Bernardino shooter’s phone and reset the password by trying too many login attempts. More telling reports have stated the local government agency who issued the phone was actually  paying a monthly service charge  for remote access to the phone (since it was not the gunman’s personal property, but was issued by his employer) but never got around to setting it up. Would-be politicians have even weighed-in, with US Presidential candidate and media circus favorite Donald Trump calling for a boycott of Apple products until the company complies with the court order. One thing is for certain, though, and that’s the reaction from consumers. It’s easy to envision millions of customers scrambling to get the content out of their phones on the off-chance that the...

CCleaner has been around for a long time, and over that length of time, has managed to carve out a solid reputation for itself. This is one of the few programs that has a permanent space reserved for itself on all of my machines. There’s not really a lot that I can add to that. It takes a few seconds to download, doesn’t hog all your system resources once its installed, and has been designed with ease of use in mind. CCleaner is one of the best tools available for optimizing your system. The nice thing about that statement is that although there are 2 pay-to-use versions available, the free version that we’re talking about today, is still better than pretty much most of the other paid versions out there. Not only that, as the years go by, the devs at Piriform just keep on making it better. Right. But how does it work? Despite what Microsoft would have you believe, Windows isn’t perfect. The OS collects unused files, documents and general bits of garbage here and there, that o...

In today’s installment of “straight out of Hollywood” (literally and figuratively), a Los Angeles hospital was nearly crippled by a ransomware attack on its network. Hollywood Presbyterian had to revert to paper medical records and registration for admitted cases, while emergency room patients were actually diverted to other hospitals, potentially causing life-threatening delays in trauma treatment. What’s so horrible about a little computer glitch that would keep a hospital from treating a critically ill  patient? Everything. Ransomware, as the name implies, is malicious software that infects a network and roots around, often  disabling critical systems and bringing business to a halt. In exchange for meeting the hacker’s demands,  a clean-up option is offered in order to restore network function. In this hospital’s case, the details are  murky  while the FBI still investigates, but some reports uncovered by ArsTechnica claimed that the hospital’s ...

Description MySQL CONSTRAINT is used to define rules to allow or restrict what values can be stored in columns. The purpose of inducing constraints is to enforce integrity of database. MySQL CONSTRAINTS are used to limit the type of data that can be inserted into a table. MySQL CONSTRAINTS can be classified into two types - column level and table level. The column level constraints can apply only to one column where as table level constraints are applied to the entire table. MySQL CONSTRAINT are declared at the time of creating a table. MySQL CONSTRAINTs are : NOT NULL UNIQUE PRIMARY KEY FOREIGN KEY CHECK DEFAULT CONSTRAINT DESCRIPTION NOT NULL In Mysql NOT NULL constraint allows to specify that a column can not contain any NULL value. MySQL NOT NULL can be used to CREATE and ALTER a table. UNIQUE The UNIQUE constraint in Mysql does not allow to insert a duplicate value in a column. The UNIQUE constraint maintains the uniqueness of a column in a table. More th...

Xiaomi on Wednesday  unveiled  its latest flagship smartphone, the Mi 5, at an event in Beijing, China. The Chinese company also revealed the Mi 5 at  MWC  in Barcelona which marked Xiaomi's first official presence at the global event. (Also see:  Xiaomi Mi 5 vs. Xiaomi Mi 4 ) The  Xiaomi Mi 5  launch comes almost two years after the  Mi 4 , which was unveiled back in 2014, and the company claims was one of the best sellers so far with sales figures close to 4 million. Considering that a lot rides on the success of the new flagship Mi 5 smartphone, the company has packed some impressive specifications under the hood as well as added some aesthetic improvements. Here are the top five features in Xiaomi's new flagship smartphone. 3D Ceramic body Xiaomi at the launch of the Mi 5 stressed that the company was looking to experiment with a new build for the new handset and that was when 3D ceramic material for the rear came up. Hugo Barra, V...

Apple is  widely reported  to be working on a 4-inch  iPhone 5se , which it  plans to launch on March 15 . The supposed smartphone will have innards largely similar to the  iPhone 6  and  iPhone 6s . But as for the design, it appears  Apple  is inclining towards the design of the iPhone 5s, but with some noticeable changes - such as a relocated power button. Citing schematics provided by an  iPhone  case manufacturer, 9to5Mac reports that the iPhone 5se will look nearly identical  to Apple's flagship smartphone from 2013. It however notes that iPhone 5se will have curved design. The iPhone 5se will also have its power button on the side, as opposed to on the top as seen in the  iPhone 5s . To recall, iPhone models starting with iPhone 6 have had their power key on the side. The report thus refutes a purported iPhone 5se render that suggested that the iPhone 5se will look identical to the iPhone 6, except for the 4-in...

OnePlus launched its  OnePlus 2  flagship smartphone  back in July last year . Although we did not hear anything about its upcoming OnePlus 3 since then, the Chinese tech firm has now given the first piece of information for the device. The OnePlus 3 is expected to launch in the second quarter of this year according to Carl Pei, Co-Founder of OnePlus,  reports  Cnet. Although Pei did not give a single detail about the upcoming handsets, he did mention the model will "captivate" users just as the company's first handset, the OnePlus One, had. He added that the OnePlus 3 will feature a "new design" indirectly suggesting users not to expect anything on the similar tracks as the OnePlus 2. Further, he said that OnePlus 3 will be arriving in the US and other markets as an unlocked smartphone and will be sold directly by OnePlus. The Chinese tech firm may also come up with a "better buying process", details of which were not disclosed. OnePlus will s...

One of the most sought after features in a smartphone - price-band notwithstanding - is a good camera. Increasingly, people are using it as a replacement for digital cameras. The onslaught of picture sharing apps like Instagram  and social video sharing platforms like  Vine  are augmenting the need for smartphones with a decent shooter. We sifted through a plethora of smartphones in the sub-Rs. 15,000 category and zeroed in on five phones that have a capable camera. Our selection process involved looking at sample photographs captured by the rear camera under daylight and checking if the captured images have accurate colour reproduction, low noise (loss of details), minimum chromatic aberration and good focusing speed. A word of caution to all readers is not to expect the moon in this price range especially with respect to the performance of the camera under low-light. We added brownie points for camera modules which had a good camera app interface, decent front-fac...
