The performance is yet another spot where the Chromebook 13 shines. As is common with Chromebooks, the very light OS it runs means that you’ll never throw more at the machine than it can handle. Powered by an Intel Celeron chip and 4GB of RAM, the Dell Chromebook 13 can handle your 16 or 17 open tabs (if you work like me), including the heaviest of websites and Chrome applications. I wasn’t disappointed by the battery life either, which easily got me through the day and charged pretty quickly as well.

I’ll assume you know a thing or two about Chrome OS by now, but very quickly: Chrome OS is essentially a web browser with a few file management features added on. But thanks to the plethora of Google services and Chrome extensions, you won’t find yourself missing much from OSX or Windows 10 for a lot of your day-to-day use. Google has made some nice updates to its OS lately as well, such as the nice task switcher, which make it feel a bit more like a full-fledged operating system.

Ultimately, Chrome OS won’t do it for everyone. You won’t be recording music, editing video, or doing any other heavy production of any kind outside of what Google’s online apps offer. But if your day-to-day use consists of activities like watching Netflix, reading articles, writing, and editing your blog—you’ll be very content with how well it does those things. For students and modern business people, you won’t regret having a Chromebook in your arsenal.

The Dell Chromebook 13 is at least a hundred dollars more than most Chromebooks—even the very excellent 2015 Toshiba Chromebook 2 ($330). When we’re talking about inexpensive laptops, I don’t take that one hundred dollars lightly.

The Dell Chromebook 13 has the better touchpad, the more premium build quality, and the better design, but for some that still isn’t going to be worth the heavier pricetag. For me, the touchpad and premium build quality alone make it worth the extra cash, elevating the computing experience to well beyond the territory of “cheap laptop”. It’s one of the best laptops under $500 ever made and has me more excited for both Dell laptops and Chrome OS than ever before.

Think your private browsing session is really private? A new paper shows how your smartphone or laptop's battery can be used to compromise your privacy.A HTML5 feature called the Battery Status API lets websites check the status of your device's battery with such precision that it could be used to track you in short time intervals, researchers claim. And that's even if you're using identity-concealing software such as Tor.SEE ALSO: Tim Cook blasts Silicon Valley companies for 'gobbling up' your personal data

To overcome the security and privacy issues, the authors of the report suggest that the readings gathered by the API be rounded. They say this would not interfere with the functionality of the API, but would eliminate the problem of tracking. At the moment, nothing more than a simple script is needed to monitor someone's movement from one website to another. The creation of a unique identifier also opens up the possibility of a phenomenon known as respawning. Even if a user goes to the trouble of deleting local-stored cookies, they could instead be remotely stored and reinstate when a user is identified through Battery Status API data.

The researchers also suggest that permission to access the API should be sought from users rather than just allowing its use by default.Security researchers have discovered that a feature of the HTML5 specification allows websites to find out how much battery power a user has left on their browsing device and the information could then be used to snoop on their online activity. Whenever your smartphone or your laptop goes low on battery, you hit the power saver mode by disabling features or apps that take up extra battery. However, the battery status API (currently supported in Firefox, Opera, and Chrome browsers) explicitly frees sites from needing to ask user permission to discover the remaining battery life. Researchers have pointed out the information a website receives is specific and even contains the estimated time in seconds the battery will take to fully discharge along with the exact battery percentage remaining.

The two numbers could be in any one of around 14 million combinations, meaning that they operate as a potential ID number. As the values update every 30 seconds, the battery status API could be used to identify users across websites, The Guardian reports. The World Wide Web Consortium, W3C, the organization that introduced the API, argues that the information “the information disclosed has minimal impact on privacy or fingerprinting, and therefore is exposed without permission grants.”

However, researchers warn that “Users who try to revisit a website with a new identity may use browsers’ private mode or clear cookies and other client side identifiers. When consecutive visits are made within a short interval, the website can link users’ new and old identities by exploiting battery level and charge/discharge times. The website can then reinstantiate users’ cookies and other client side identifiers, a method known as respawning.” By now, you probably know that using a smartphone in just about any way will send personal data across the Internet. Service carriers log text messages and details about calls. Third-party apps can access or upload identifying data. Weather- and map-based services track a user’s geographic location. It seems that even the most passive, inoffensive service on our phones can leak our information.

Battery-life indicators—tiny icons that usually hover at the top of a screen—show how much charge a device has left before it needs to be connected to a power source. Though useful, these indicators might not be as innocuous as we think, according to a team of four European cybersecurity researchers. The experts recently authored a paper titled “The Leaking Battery” that explains how websites can access a user’s online browsing activity just by monitoring his or her device’s battery status—which means that data can be taken not just from mobile phones, but also laptops. When browsers give battery information to websites, they expose a “fingerprintable surface that can be used to track web users in short time intervals,” the researchers write.

Why does this happen? Under current rules from the World Wide Web Consortium, the organization that sets global Web standards, sites are allowed to get details on a user’s battery status in order to help save energy. Upon detecting low battery, sites can turn off power-sucking features and display an energy-saving page instead. The consortium permits sites to retrieve these details without asking permission because the feature was deemed to have a “minimal impact” on privacy. But information about a phone or laptop’s battery life can be oddly specific—so much so that it can be used to identify one user from another. Here’s how that works, succinctly explained by the Guardian:

The researchers point out that the information a website receives is surprisingly specific, containing the estimated time in seconds that the battery will take to fully discharge, as well the remaining battery capacity expressed as a percentage. Those two numbers, taken together, can be in any one of around 14 million combinations, meaning that they operate as a potential ID number. What’s more, those values only update around every 30 seconds, however, meaning that for half a minute, the battery status API can be used to identify users across websites.

For instance, if a user visits a website in Chrome’s private browsing mode using a VPN, the website should not be able to link them to a subsequent visit with private browsing and the VPN off. But the researchers warn that that may no longer work: “Users who try to revisit a website with a new identity may use browsers’ private mode or clear cookies and other client side identifiers. When consecutive visits are made within a short interval, the website can link users’ new and old identities by exploiting battery level and charge/discharge times. The website can then reinstantiate users’ cookies and other client side identifiers, a method known as respawning.” The possibility of this kind of microlevel tracking might not be surprising to jaded consumers who are used to hearing about all sorts of Web-based data breaches these days. Still, it’s certainly unnerving. And the researchers’ report comes on the heels of many other recent revelations about unexpected identification.
