How To Never Forget a Password Again

It seems like every time you turn around there is a new data breach with experts warning everyone to change their passwords. This means not just changing your password once for every website and online service you use, it usually means changing it on your home computer, your work computer, your smartphone, and your tablet if you own one.

When it comes to online security, one of the best things you can do today is to use a password manager. Not will you never need to memorize dozens of passwords, you don’t even need to know what they are. A good password manager creates passwords for you, fills them in and remembers them across multiple devices.

The Myth of Strong Passwords

A few years ago, a combination of lowercase and uppercase letters and a number or two were all you needed to create a strong password, provided you didn’t use a name or a word found in the dictionary. That just isn’t true anymore. Today’s password cracking programs can hack most eight-digit passwords in a minute or less. If you use something clever – and common – like, paSSword, or trustno1, it can be cracked in milliseconds.

What Makes a Strong Password

The most important aspect of a strong password today is its length, regardless of what characters you use. A password like mulberrystreet, which contains 13 letters is much stronger than even a complex password like 9L*rtPq1. The first would take over 50 years to crack – according to the website How Secure Is My Password? – while the shorter password would take a few hours. A series of 20 random characters would take the same software about a billion years. If you used a password that was 22 characters long, every star in the galaxy would burn out and grow cold before a hacker’s computer could figure it out.software about a billion years.

On your computer, it is usually a browser plugin, while on a tablet or smartphone, it’s a small app.

You need to remember only one password – the one that opens the password manager. When you go to a website, it fills in the username and password for you automatically. If you want to change your website password or create an account on a new website, it will generate one for you automatically, usually between 20 and 22 characters long. Your login information is kept encrypted and is updated between all of your devices automatically as soon as you connect to the internet. Some are free, while others require a small annual fee, while most offer a free version with payment required for advanced features.devices automatically as soon as you connect to the internet. Some are free, while others require a small annual fee, while most offer a free version with payment required for advanced features.

Using the Cloud Vs. Local Storage

Before choosing a password manager, you should first decide whether or not you are comfortable with your passwords being stored in the cloud, or if you would prefer they be stored only on your devices. When companies refer to the cloud, of course, they mean their own servers. While the majority of password managers do keep this information encrypted, it is a matter of comfort and personal preference. Millennials, for example, are more trusting of cloud-based services, while older generations may prefer having their information stored on their own devices. KeePass, 1Password and SplashID offer local storage, while Dashlane and LastPass use encrypted cloud-based storage.devices. When companies refer to the cloud, of course, they mean their own servers.

Laptop Battery Maintenance Tips

The batteries in a laptop will not have to be replaced often, if they receive proper maintenance. Most users will plug in the power cord when their batteries are running low, but they do not remove and check the laptop battery until it goes dead. When you take care of your laptop, cords and battery, you will be able to prolong the life of your computer hardware.

Always Fully Charge Laptop Batteries

Chargeable batteries will wear down quickly, when they are only charged for a short period of time. When the laptop is not in use, such as at bedtime, plug it into an outlet and leave it to charge until the battery power is full. When you first buy a laptop or any electronic device that needs to be charged before you can use it, always charge it to full capacity. A laptop will work with only a small bit of power, but if it is not fully charged frequently, it will start to lose its ability to hold a charge.

Power Management Tools


Every computer and laptop has options that allow them to make changes to the power management tools. In a Windows laptop, check under "Control Panel" and you will find the power options. You will be asked to identify the type of computer that you are using. It is important to choose "Laptop" from the drop down menu. Each type of PC will bring up a different option that will save power. For a laptop, the power management tools will set a time to turn on the screen saver, or it will shut down the hard drives if the notebook sits idle for a specific amount of time. By turning off hardware that is not in use, the laptop will not use as much power and the batteries will not die as fast.

Close Unnecessary Programs


Look at the programs that start up along with your operating system. If you don't have to use them immediately, right click on the icon and go into options. Scroll through the list until you can turn off the option to have the program open whenever you start the laptop. When you use an application, close it when you are done. Programs that are left open will use system resources and power that are needed for other software. If you only have a few programs open at the same time, the laptop will use less power and it will be able to stay on battery power longer.

Purge and Discharge Laptop Batteries

At least once a month, every laptop user should purge and discharge their batteries to prolong their life. To purge a laptop, remove the AC power cord. Turn on the laptop and let the battery drain until the low battery sign pops up. Plug in the power cord and let the notebook charge to full capacity while the laptop is still on. Batteries can be discharged in a similar fashion. Go into the power management option and turn off all of the power saving tools including hibernation, sleep mode and the screen saver. Allow the battery to drain completely until the laptop shuts itself off. Without turning on the laptop, reconnect the power cord and allow it to charge until the battery is full.

Use AC Power


Most laptop users will plug in the AC cord even when the battery is not low. However, this is also causing the battery to drain in small increments. Before you use the laptop, remove the battery and then plug in the power cord, so that the laptop is running on only AC power. Store the battery on a cool, dry surface and replace it when you shut off the laptop.


How to Update an Old Computer

If you've noticed your old computer is a bit sluggish or isn't performing at 100 percent, it may be time to update it. Often the software or hardware in your machine can become outdated only months after you purchase it, creating incompatibilities and crashes. There are a myriad of ways you can update your old computer, so it's important to analyze the problem before rushing out to buy new components. And remember that individual components can be updated, saving you from purchasing an entirely new computer.

1
Determine exactly what needs to be updated. For example, do you need new software, or hardware? If your hard drive lacks free space, it may be time to upgrade to a larger drive. Check how much space you have left by right-clicking the hard drive icon (usually the "C" drive) and selecting “Properties.” The amount of available space will be displayed in the following dialogue box. If your computer is running slow, you may need to upgrade the processor, or the Random Access Memory (RAM). RAM is the temporary memory your computer uses when it is actively working. Increasing the amount of your RAM is generally the most effective computer upgrade you can make. Consult your owner's manual to determine which drives, memory cards or processors are compatible with your computer's motherboard.

2

Research components and products that are on the market. Magazines like PC World (see link in Resources) have thousands of product reviews you can browse to find the right item for you. Shop around for the best prices, as many items can be bought online for a fraction of the retail price. Bear in mind that sometimes the cost of purchasing and installing certain components, such as the processor or motherboard, can be greater than buying a new computer.

3

If your system only has a CD drive, consider replacing it with a DVD drive. If you watch videos, listen to music or play games on your computer, consider upgrading your video and/or audio cards.

4

Install your components according to the manufacturer's specifications. If you're upgrading software, simply insert the CD and follow the installation prompts. If you're installing new hardware, investigate if your upgrade can be done as a do-it-yourself (DIY) project; you may be able to save yourself a few dollars in labor costs. But if you aren't confident tinkering around in your machine, call in the experts to do the work for you.

Warning


Doing DIY upgrades on your computer may void your warranty. Check with your supplier before doing any work.

7 Ways to Use Your Old Smartphone

Getting a new smartphone is always exciting. Not only do you get more power and more features, but a new phone is also usually faster and in better shape than your old one. However, this begs the question: What should you do with your old phone? Rather than letting it gather dust or sit in a drawer in a state of permanent mute, here are seven ways you can give your old phone a renewed purpose.

1. A Versatile Universal Remote

Many of the Android smartphones released over the past several years contain the same infrared technology used by your TV remote control. If your phone contains what is commonly called an IR blaster, you should have no problem downloading an app and using it it as a universal remote for your entertainment room. Perhaps the biggest benefit of these apps is that if you’re doing a search for your favorite TV show, you can just type it into your phone, rather than scrolling through the alphabet one letter at a time.

If your old smartphone doesn’t have an IR blaster – like the iPhone or Samsung Galaxy models after S6, you still may be in luck. Apple TVs and most WiFi-enabled smart TVs have apps that will work over your home network.

2. A Portable Media Player

When the iPhone was first released back in 2007, Apple described it as a widescreen iPod with touch controls and a built-in mobile phone. Once you remove the SIM card, what you are left with is an advanced iPod. Most Android models have the added benefit of adding additional storage with an SD card. Delete the apps you no longer need, and fill your old phone with all of your favorite music, videos and photos. Not only will this free up space on your new smartphone, it will help prolong the battery life if you aren’t using it to listen to music all day.

3. An Onboard Computer and Nav System

If your car doesn’t already have a sophisticated computer system, GPS and on-dash display, it may be worth turning your old smartphone into an onboard computer. Just get a decent dashboard mount for your phone, connect it to your stereo with its headphone jack – or bluetooth if your car comes equiped – and load up your favorite songs too. Even without a cellular data plan, your old smartphone should work as a reliable GPS, since GPS systems are independent of cellular data.

4. A Security Camera or Baby Monitor

Provided your smartphone can connect to your home WiFi network there are many things you can do with its video and audio capabilities. There are hundreds of apps available that turn your phone into a video monitoring tool, without the need of cellular access. Mount your old phone in your front window to see who’s at the door, put it in your baby’s room to keep an eye on her while you’re downstairs watching TV, or even use it to keep an eye on your dog while you’re at work. Depending on which app you get, the phone can alert you when there is motion, or send you a constant video and audio feed from home, wherever you might be at the time. Some of the apps do cost a few dollars, but are much more affordable than buying a dedicated IP camera.

5. A Cheap Gaming Platform


Any parent with young children know that a smartphone touchscreen is irresistible to tiny hands. Yet at $1,000 or more for the latest technology, letting a child play with your phone can be an expensive accident waiting to happen. Letting your kids play with your old phone, however, reduces the potential cost considerably. Load up some games and let them have fun! A few sticky fingerprints won't matter nearly as much.

6. Connected Digital Storage

Even if you don't need the audio and video capabilities of your old smartphone, there's probably still a lot you can do with the digital storage space. A Wi-Fi-enabled portable flash drive can cost hundreds of dollars, just to do what your old phone does already. Use it to keep backup copies of your most important files, you contacts and photos. If you have an Android, swap out the storage card with a larger one to give yourself lots of extra room.

7. Pass It On


If your phone is still in working condition, or if its parts can be salvaged, there are thousands of people who could really use it. Verizon's HopeLine, for example, has collected hundreds of thousands of phones, which it gives to victims and survivors of domestic violence, along with free cellphone minutes. If the screen is cracked, they may be able to replace it before passing it on to someone else, or use its components to repair another phone.

Even if your old smartphone can't be used by someone else, its components can always be recycled. Smartphones contain rare metals that may be soon in short supply, so manufacturers have a financial incentive to recycle the products they sell. Apple, for example, has a recycling program in most countries where it sells its iPhones. You may even receive a free gift card for your recycling efforts.

Dell's Inspiron 15 7000 gaming laptop gets serious with GTX 1060 and Nvidia Max-Q



Dell’s Inspiron 15 7000 gaming laptop is getting a little more serious this year, graduating to GeForce GTX 1060 discrete graphics and using Nvidia’s Max-Q technology to put more power into (slightly) less space.

The jury’s actually still out on Max-Q—gamers are openly leery of potential compromises. Looking at the main differences between the refreshed line announced Wednesday, however, and the prior generation, you can see how Max-Q is starting to change how laptops are designed.

The Inspiron 15 7000 gaming laptops will begin shipping in September. Prices start at $999 for FHD-based configurations and $1,449 for UHD-based configurations, with these main options:

CPU:

l 7th-gen Intel Core i5-7300HQ quad-core with clock speed up to 3.5GHz

l 7th-gen Intel Core i5-7700HQ quad-core with clock speed up to 3.8GHz

RAM: 4GB to 16GB (maximum 32GB) of 2,400MHz DDR4

Display (non-touch):

l FHD (1920x1080) IPS

l UHD (3840x2160) IPS

Graphics:

l Nvidia GeForce GTX 1050 with 2GB of GDDR5 memory

l Nvidia GeForce GTX 1050 Ti with 4GB of GDDR5 memory

l Nvidia GeForce GTX 1060 with Max-Q and 6GB of GDDR5 memory

Battery: 56Whr, 4-cell

Considering how Dell's prior generation Inspiron impressed us for its bang for buck, the fact that much remains the same here is a good thing. The new lineup does have a higher starting price, but it’s adding fancier options like the 4K display and the GTX 1060 with Max-Q technology, plus a dual-fan cooling system and a fingerprint reader for Windows Hello. (Maybe it also has better FHD display quality—we didn’t much like the last generation’s.)

Meanwhile, it subtracts battery: The prior generation had a larger 74Whr, 6-cell pack compared to the much smaller one on the new models. Max-Q is supposed to help manage power consumption better. Dell promises anywhere from 7 to almost 10 hours of life depending on the configuration (and of course, what you’re doing). This is in line with our test results for the prior model, so the latest generation is potentially giving you the same battery life with less actual battery. There's also a new quick-charge technology that will replenish the battery to 80-percent capacity within an hour—that’s nice if you’re actually taking this thing anywhere.

Chances are you won’t take it far, though. Compared to its predecessor the Inspiron 15 7000 gaming laptop is slightly thinner (0.98 inch compared to an even 1 inch before), but heavier: 5.82 pounds and up for a GTX 1050-based model, and 6.28 pounds and up for a GTX-1060-based model. Last year’s version started at 5.76 pounds.

Note, too, the differences in AC adapter: A 130-watt model for GTX 1050/1050Ti versions, and a 180-watt model for GTX 1060 versions. The larger adapter will be bulkier, of course.

The Inspiron 15 7000 gaming laptop is just one example of the new wave of Max-Q laptops, joining the Asus ROG Zephyrus and others. In this case, it seems to be taking advantage of the technology to fit more features into the same space rather than go thinner. We don't know whether it'll also be quieter. Even with a higher starting price, however, we expect this model will continue to offer a lot of value for gamers.

Android TV: The Oreo update isn't enough


We’ve seen signs that Android TV might step out of Chromecast’s shadow throughout the year. The software has been popping up on new devices, such as AirTV and Nvidia’s second-generation Shield TV, and enabling novel over-the-air DVR solutions like Tablo Engine and Plex. Even Google seemed to be giving more love to its lesser-known living-room platform, announcing plans to integrate Google Assistant and overhaul the Android TV interface.

But after installing Android 8.0 Oreo on a Nexus Player this week, I’m not sure an Android TV comeback is imminent. The new software is a mess on Google’s three-year-old streaming box, and it’s missing several features that Google showed off at its I/O developers conference in May. Meanwhile, there’s been little evidence of new streaming boxes to carry the platform forward, and it’s unclear if existing ones like the Shield will get upgraded to Oreo anytime soon.

Perhaps I’m expressing these concerns prematurely, and some big reveal is forthcoming with new Android TV hardware and improved software. Still, it’s hard to see how that happens with the state Android TV is in now.

Oreo on Android TV


On the surface, Android 8.0 Oreo is a major upgrade for Android TV. The home screen allows each app to have its own row, or “channel,” where it can recommend movies or shows to watch. Those apps can also feed into a “Watch Next” row for catching up on new episodes of previously watched programs. The layout is a nod to the grid-based guide you’d find on a cable box, and an attempt to make browsing through streaming apps much simpler.

But right now, Oreo on Android TV lacks several features that Google demonstrated a few months ago. The Watch Next row is empty, for instance, because shows aren’t populating the list automatically as they should, and attempts to add them manually result in a “Can’t add to Watch Next” error. Netflix’s previously announced home screen integration hasn’t arrived yet either—though the company tells me it’s still working on it—and video thumbnails aren’t appearing on channels like Google Play Movies & TV.

Google Assistant is also a no-show, so you can’t launch directly into videos from Netflix or YouTube with voice commands, control smart-home devices, or access third-party voice skills. The search results screen is the same as it has been in previous versions of Android TV. (Google said in January that Assistant would arrive on Android TV—including older versions—in the “coming months,” which seems conveniently non-committal in hindsight.)

Even basic operation of Android 8.0 Oreo veers into unpleasantness on the Nexus Player. The device stutters and lags at every step, and flashes a blank screen every time I tap the remote after waking the device from standby. And when pressing the remote’s voice search button, the device consistently takes a few seconds to produce any response on the screen. Also, Sony’s Crackle—one of the earliest streaming apps to support Android TV—doesn’t even work. This is the stuff of beta software, not a major, publicly available upgrade.

Pixel Player, where are you?

Judging Android 8.0 Oreo by its performance on a three-year-old streaming box might be harsh, but right now the Nexus Player is the only device that supports the new software. For developers who want to optimize their apps for Android 8.0, this is the experience they’re going to get.

The obvious fix on Google’s part would be to release a new halo device for Android TV, a “Pixel Player,” if you will. Imagine, for instance, a sub-$100 streaming box with 4K HDR video support, a voice remote for Google Assistant—maybe even with hands-free operation—and deep hooks into services like YouTube TV and Google Photos. Google could even bundle a USB TV tuner to showcase Android TV’s over-the-air channel integration. Beyond just serving as a reference for app makers, a device like this could help put Android TV on the map for consumers.

But so far, there’s been little evidence that Google will back its living-room operating system with new hardware. A report in May by Cord Cutters News claimed that Google was working on a new streaming player, but the site later backed off that claim, saying that the device may instead be another third-party offering similar to Xiaomi’s Mi Box. (The Mi Box, by the way, arrived in late 2016 with no fanfare from Google, was only sold in Walmart stores, and is not even running the second-latest version of Android as of this writing.) Other recent reports on Google’s upcoming hardware plans haven’t mentioned Android TV at all.

Looking out to other vendors, the future for Android 8.0 Oreo gets even murkier. Google did recently name Sony and Sharp among the device makers that plan to “launch or upgrade devices to Android 8.0 Oreo” by year-end, so it’s possible we’ll see new or existing smart TVs running the latest software before long. But Nvidia, which until now has carried the Android TV set-top business on its back with the $200 Shield TV, was conspicuously absent from that list.

Android TV’s time

On some level, fretting about the state of Android TV is academic. Google has said the platform sees 500,000 device activations per month, in part because of the company’s deals with smart-TV makers such as Sony and overseas pay-TV operators such as KDDI in Japan. Android TV’s app ecosystem also enjoys an unusual symbiotic relationship with Amazon’s Fire TV, which runs a modified version of Android, so apps that arrive on one platform also tend to show up on the other soon after. Even without challenging major streaming devices like Roku or Fire TV, Android TV is somewhat healthy.

But “somewhat healthy” can’t be what Google is aiming for, especially as Chromecast loses its competitive edge among consumers. According to a recent Parks Associates report, Chromecast lost market share in the United States over the last year, and is now in third place behind both Roku and Amazon Fire TV. Consumers are starting to vote for proper remote controls and on-screen interfaces over Chromecast’s phone-as-remote approach, which in turn means Google is losing turf in the battle for the connected home.

Android TV could be the solution, but it’s unclear if Google will start treating it that way.

Dell revs up its XPS 13 with Intel's quad-core Kaby Lake R


The 8th-gen CPU promises up to 40 percent faster performance, a significant jump from before.

Dell’s XPS 13 is already a great laptop. Now imagine that laptop performing 40 percent faster than it does now. That’s the promise of the CPU refresh Dell announced for the product line on Monday at IFA in Berlin. The XPS 13’s two highest-end SKUs will have Intel’s latest 8th-generation Core chips, called Kaby Lake R.

The updated XPS 13 product line will start shipping September 12 with a base price of $799, but that model is not Kaby Lake R-fortified. (In fact, five of the seven CPU options for the XPS 13 will still use Intel’s 7th-generation Kaby Lake CPUs.) The Core i7 Kaby Lake R Core i7 model will have a starting price of $1,400.

Quad-core chips make a difference

The 8th-generation Kaby Lake R CPUs will be the first to offer quad-core processing power (four cores and eight threads) for ultrabook machines. Intel’s promised performance hike is based on tests comparing the 8th-generation Core i7 to the 7th- generation Core i7 (Kaby Lake) part. We got a more pedestrian 12- to 19-percent jump moving from 6th-gen Skylake to 7th-gen Kaby Lake.

Dell is upping the ante even more, however, claiming a jump of up to 44 percent in its XPS 13 implementation. The two Kaby Lake R CPUs in the XPS 13 line will be:

The entry-level Core i5-8250U, with a base clock speed of 1.6GHz and a boost speed of up to 3.4GHz

The midrange Core i7-8550U, with a base clock speed of 1.8GHz and a boost speed of up to 4GHz

Why this matters: As one of the first laptops to ship with Kaby Lake R, the Dell XPS 13 ushers in an intriguing new era for laptops, one where quad-core power could start to erase the compromises between portable and desktop PCs. We’ll let you know more if we have a chance to benchmark the XPS 13 ourselves.
