As many of you know, processor's clock frequency improvement got stuck in about 2003, causing the origin of multicore CPU (and other technologies). In this article I'll introduce you on how to run code simultaneously in various processors (I suppose that all of you have a multicore CPU). When you write code without any parallel directive, it only executes in one CPU at the same time (see it below). OpenMP make simple to work with various cores (if not with all of them) , without so much heada...
Hello, everyone! Many of you don't even know about my existence here on Null Byte, so I thought of contributing something rather interesting. Recently, someone asked how to make your own "Bad USB," and I promised to make a how-to on this topic. In addition, it would be nice to have something related on our WonderHowTo world. So here it is!
The new iPhone 6S and 6S Plus models have a really cool feature called 3D Touch that lets you perform app-specific Quick Actions from the home screen for apps that support it. The only downside is that this awesome new feature is not available on older iOS devices.
While password cracking and WPS setup PIN attacks get a lot of attention, social engineering attacks are by far the fastest way of obtaining a Wi-Fi password. One of the most potent Wi-Fi social engineering attacks is Wifiphisher, a tool that blocks the internet until desperate users enter the Wi-Fi password to enable a fake router firmware update.
By now, a mobile phone that isn't "smart" is about as hard to come by as a TV that isn't high definition. As a result, members of older generations who were previously reluctant to purchase a newfangled smartphone have no other choice but to cave into the more recent trends when their old device finally breaks down.
There are over 1.6 million apps on the Google Play Store, which makes it the largest collection of mobile apps on the planet. However, a large portion of this total is occupied by apps with overlapping functions—think social media, news, weather, music players, and various other categories where developers compete against one another to garner the largest user base.
Welcome back Hackers\Newbies!
Accidentally deleting important files can happen as easily as swiping left on something and watching it disappear into the ether. Of course, Apple allows automatic backups through iCloud, which ensures that your data is always stored safely in the cloud in case of emergency.
In response to the success of Apple Pay and an attempt to stave off the appealing Samsung Pay service, Google is completely revamping Android's mobile payments system. Instead of just using Google Wallet as an app to make payments with your phone, a new service called Android Pay, with an extensive underlying framework and API, will soon make its debut—and maybe even sooner than you'd think.
People like to cite the iPhone as the device that started the smartphone craze, but the truth is, smartphones had existed for years by the time Apple got into the game. The real groundbreaking feature that this device brought to the table was a multi-touch screen to go along with its "smart" functionality, and this is still the main method we use to interact with our devices today.
Everyone's favorite Android modding tool is finally available for the Galaxy S6 and S6 Edge. Thanks to some hard work by Wanam and a few other developers, we can now install the Xposed Framework on Samsung's latest mid-sized flagship phones.
So you finally decided to make the switch from iOS to Android, huh? Well first off: welcome to the world of tomorrow. And secondly: good call, mate.
As it stands, Firefox OS isn't a very popular third-party operating system for Android devices, especially when compared to others like CyanogenMod, but Mozilla developer Fabrice Desré is attempting to change that.
Google I/O is like Christmas for Android enthusiasts. Every year, this conference showcases new and upcoming features for the world's leading mobile operating system, and this year's was no different. Shortly after announcing Android M, Google released a preview version of the upcoming firmware for Nexus devices.
There are several reasons that you might want to restore the factory firmware on your device—maybe you need to send your phone back for warranty purposes, or perhaps you're getting ready to accept an over-the-air update and need to unroot first. In some cases, reverting to the stock firmware can even resurrect a soft-bricked phone.
AMOLED display panels like the one found in most Samsung Galaxy devices, including the Galaxy S6 models, are known for their deep blacks and vivid colors. The downside here is that the colors tend to be over-saturated and not very realistic.
Dolby may have made a lot of Android users angry by only offering their Atmos surround sound equalizer to Lenovo and Amazon, but we all know that exclusivity is only temporary in the Android world. Thanks to worstenbrood, we now have a ported version that can be installed on any device running Android 4.3 and above.
With an Android device, you can replace almost any default app with a third-party offering. Don't like your home screen app? Replace it. Tired of the text messaging interface? Upgrade it. The same can be said for Android's lock screen. But while many third-party lock screen apps are available, so far, only one has been designed with the Samsung Galaxy S6 and its fingerprint scanner in mind.
The buttons on most Android devices are laid out (from left to right) in a Back, Home, Recent Apps format. Samsung is the lone exception to this rule, which flip-flops them, so this can make for an inconsistent experience if you own multiple Android devices.
Rumors have had Google making a foray into the mobile carrier world for quite some time, but today, the Mountain View tech giant finally made things official. The new service, dubbed Project Fi, will be a Mobile Virtual Network Operator, or MVNO, that uses existing Sprint and T-Mobile cell towers.
When purchasing a new phone, one of the most vital features to consider is battery life. Everyone wants to know how long they can use their device without needing to hug a wall. Increasingly, more and more manufacturers ship their devices with some variation of a "battery saving" mode, which can help combat dead-phone issues in times of dire need for battery life.
The Google Now gesture included in the Google Now Launcher and on Nexus devices isn't something I regularly utilize, and you might not either. There is a way to disable it, which is a good idea if you were executing it accidentally, but what's even better than disabling it? Repurposing it!
If you're playing the Android version of Game of War, or pretty much any other game (including emulators), it's much easier to play using a controller. While most Android games have gamepad support built-in, others do not and require a root app like Tincore to map touches into buttons.
Cards Against Humanity is a popular party game with good old-fashioned raunchy adult themes that go quite well with a few alcoholic beverages. Up until now, though, you had to either print out a set of cards or order the official deck to play—unless, of course, all players happened to have devices that sported the same operating system.
HTC's Sense UI is generally regarded as one of the best manufacturer-skinned versions of Android. This is mainly due to the subtle and classy styling of the interface, as well as some unique features that are added in here and there.
As technology continues to advance, we as consumers are privileged enough to be able to take higher quality photos and videos and listen to clearer and better-sounding music on our mobile devices. But sometimes we forget that there's a price to pay for that awesome content—enormous file sizes.
Yes, they're called volume keys, but they can do much more than adjust your volume. With minimal effort, you can do some amazing things with these physical buttons, like secretly record videos, toggle on your flashlight, scroll through pages, control your music, and much more. And while using them to wake your screen is useful, let's take it a step further and show you how to use them to completely unlock your device, even if the screen is off.
If you're a fan of double-tap to wake gestures, you're going to love the newest app from ElementalX developer Aaron Segaert. On supported kernels, it allows you to associate custom apps and activities with each of the wake gestures you've set up, which will immediately be launched even with the screen off.
Google debuted YouTube Music Key in November, and for $10 a month, this essentially turned YouTube into a music streaming service. With ad-free music videos and background audio playback, YouTube serves as a viable alternative to Spotify or Pandora for Music Key subscribers.
Android Lollipop promises tons of new features and functionality when it comes to a device near you, but as we wait, it's almost painful to see the screenshots and demo videos from Nexus devices and how downright pretty the new operating system looks.
Using my Nexus 7 tablet as a flashlight to light my path on the way to my room late at night is difficult, and honestly, useless. It doesn't have an LED flash for pictures, so using it as a flashlight is essentially just me brightening the display as high as it can go.
When my Nexus 5 received the Lollipop update, one of the first things I noticed was how subtle and quiet the new lock and unlock sounds were. Sure, this is a minor quibble, but it's also an easy fix.
After the Galaxy Note 3 firmware updated to NF4, Samsung decided to remove the option to hide apps in the app drawer, replacing it with an uninstall/disable feature instead. Before, with the hide feature, you could simply hide third-party apps that were barely used or that you didn't want others to see. Now, you can only completely get rid of them.
Does your Samsung Galaxy Note 3 feel slower than it used to? Background processes, cached files, malicious applications, and buggy updates can all lead to a sluggish smartphone. It's just what happens over time.
Android's beauty is in its customization; you can have widgets for anything, launchers that look and feel completely different from one another, and fonts you can change at any time. And it doesn't stop at aesthetics—you can go much deeper than looks.
Before Continuity and Handoff were even announced, Pushbullet was already allowing users to quickly send notes, links, and photos between their devices with a few clicks.
Unless you own a Samsung device, your Android's navigation buttons have probably always been in this order (from left to right): "Back," "Home," "Recent Apps." But depending on which hand you use to hold your phone, this may not be the most ergonomic layout for you.
Picture this scenario—you're using your phone in a dimly-lit room, then you move to an area with a lot more ambient light, and Auto Brightness kicks in within a few seconds to ramp up the backlight. That's the way it should be, right? But then you move back to the darker area, and your phone takes 30 seconds before it decides to dim back out. Pretty annoying, isn't it?
Android "Lollipop" introduced a ton of cool new functionality. Unfortunately, the Nexus 5 didn't get all of these features, as some were exclusive to other devices. For example, the Ambient Display function on the Nexus 6 that shows new notifications as they come in with a black-and-white lock screen. Sure, the new Nexus phablet has an AMOLED display that doesn't waste any battery to power black pixels, but it would be nice to have this feature as an option on the Nexus 5, wouldn't it?
With most of HTC's staff working on getting Sense updated to Android Lollipop, their piecemeal approach to individual app updates now comes to their Gallery app. The new update is available for all HTC devices running KitKat, but if you have the HTC Service Pack installed, it will run on any Android device running 4.4 or above.
