AWS announces a slew of new Lambda features – TechCrunch

AWS launched Lambda in 2015 and with it helped popularize serverless computing. You simply write code (event triggers) and AWS deals with whatever compute, memory and storage you need to make that work. Today at AWS re:Invent in Las Vegas, the company announced several new features to make it more developer friendly, while acknowledging that even while serverless reduced complexity, it still requires more sophisticated tools as it matures
It’s called serverless because you don’t have to worry about the underlying servers. The cloud vendors take care of all that for you, serving whatever resources you need to run your event and no more. It means you no longer have to worry about coding for all your infrastructure and you only pay for the computing you need at any given moment to make the application work.
The way AWS works is that it tends to release something, then builds more functionality on top of a base service as it sees increasing requirements as customers use it. As Amazon CTO Werner Vogels pointed out in his keynote on Thursday, developers debate about tools and everyone has their own idea of what tools they bring to the task every day.
For starters, they decided to please the language folks introducing support for new languages. Those developers who use Ruby can now use Ruby Support for AWS Lambda. “Now it’s possible to write Lambda functions as idiomatic Ruby code, and run them on AWS. The AWS SDK for Ruby is included in the Lambda execution environment by default,” Chris Munns from AWS wrote in a blog post introducing the new language support.
If C++ is your thing, AWS announced C++ Lambda Runtime. If neither of those match your programming language tastes, AWS opened it up for just about any language with the new Lambda Runtime API, which Danilo Poccia from AWS described in a blog post as “a simple interface to use any programming language, or a specific language version, for developing your functions.”
AWS didn’t want to stop with languages though. They also recognize that even though Lambda (and serverless in general) is designed to remove a level of complexity for developers, that doesn’t mean that all serverless applications consist of simple event triggers. As developers build more sophisticated serverless apps, they have to bring in system components and compose multiple pieces together, as Vogels explained in his keynote today.
To address this requirement, the company introduced Lambda Layers, which they describe as “a way to centrally manage code and data that is shared across multiple functions.” This could be custom code used by multiple functions or a way to share code used to simplify business logic.
As Lambda matures, developer requirements grow and these announcements and others are part of trying to meet those needs.

Jeep’s Wild Wrangler Magneto 3.0 Concept EV Is Going Out With A Bang

To go with that, Jeep has added Dynatrac 60 front axles (5.38:1 ratio) and Dynatrac 80 rear axles (5.38:1 ratio), along with 20-inch off-road beadlock wheels and 40-inch mud terrain tires. The whole thing is lifted by three inches compared to a standard Wrangler. The result, the automaker says, is an EV that excels in off-road situations, not least because of how controllable the power delivery is.
“When you’re rock crawling, you need to be very neat and clean with your driving,” Mike Allen, Jeep Design Chief, says, “especially if there’s a cliff next to you, you need to be very controlled with that.”
To help, Jeep has added a power selection switch. On the one hand, you can have the maximum 650 horsepower and 900 lb-ft of torque; alternatively, the standard setting tamps it down to a more conservative 285 horsepower and 273 lb-ft. Allen says the range is around 150 miles, though that — nor charging times —was never meant to be the Magneto concept’s focus.

The Best Mods & Upgrades That Can Give New Life To A C4 Corvette

Replacing your restrictive and likely corroded factory exhaust with a new cat-back exhaust is one of the best power adders that you can do to your C4 Corvette. The term “cat-back” refers to the section of the system that is downstream of the catalytic converter, a device that removes harmful emissions from exhaust gases.
An aftermarket exhaust with modern muffler technology will reduce backpressure, allowing more air to flow into the engine, which increases horsepower. According to the popular aftermarket exhaust manufacturer Corsa, a cat-back system for the L98 engine (the most common C4 engine) adds 14 horsepower and 16 foot-pounds of torque to an otherwise stock powerplant — all while adding a deep, muscular exhaust note that’ll make your C4 sound like a Corvette should.
Returning to catalytic converters for a moment, they’re typically long-lasting but may eventually fail by becoming contaminated, clogged, or overheated, leading to decreased horsepower. In the process of installing a cat-back exhaust, it’s worth inspecting or proactively replacing the catalytic converter itself. High-flow performance converters are available which will boost horsepower beyond the cat-back exhaust alone, yet still keep your vehicle compliant with the emissions guidelines of the EPA and local authorities.

6 Easy Ways To Unlock Your Android Phone Without A Password

For years, fingerprints have been the de-facto phone unlock method because of the method’s incredible convenience and relative security. While a bad actor can, in theory, replicate your fingerprint, and while some Android phones have had fingerprint reader bugs, the majority of the time it’s secure enough to trust while allowing you to access your device in less than a second.
Many modern Android phones utilize an under-display fingerprint sensor that uses either an optical light sensor or ultrasonics to analyze registered fingerprints, while others place a trusty capacitive sensor on the back of the phone or the power button.
Importantly, optical sensors are the easiest of the three to fool in the event someone gets access to your fingerprint. Law enforcement can be especially aggressive should they invent a reason to search your device, having once tried to use a dead man’s finger to do so. However, Android stores fingerprint data in a Trusted Execution Environment, an encrypted section of the phone’s memory that cannot be accessed by the main CPU or by apps.
Setting your fingerprints up can be a bit of a hassle, as some Android phones can be finicky. It may be a good idea to register the same fingerprint twice if you find that your phone’s fingerprint sensor has a hard time recognizing your preferred digit.
