Tensorflow Tutorial Uses Python

See the original posting on Hackaday

Around the Hackaday secret bunker, we’ve been talking quite a bit about machine learning and neural networks. There’s been a lot of renewed interest in the topic recently because of the success of TensorFlow. If you are adept at Python and remember your high school algebra, you might enjoy [Oliver Holloway’s] tutorial on getting started with Tensorflow in Python.

[Oliver] gives links on how to do the setup with notes on Python versions. Then he shows some basic setup operations. From there, he has the software “learn” how to classify random points that either fall into a circle or don’t. …read more

Junkyard Crossbow Aims to be a Car Killer

See the original posting on Hackaday

[James], aka [Turbo Conquering Mega Eagle], is not your typical Hackaday poster boy. Most of his builds have a  “Junkyard Wars” vibe, and he’d clearly be a good man to have around in a zombie apocalypse. Especially if the undead start driving tanks around, for which purpose his current anti-tank compound crossbow is apparently being developed.

At its present prototype phase, [James]’ weapon o’ doom looks more fearsome than it actually is. But that’s OK — we’re all about iterative development here. Using leaf springs from a Toyota Hi-Lux truck, this crossbow can store a lot of energy, which is …read more

Using Kotlin With Ktor to Create Web Apps

When Google made Kotlin an official language for Android a few months ago at Google I/O, the language quickly gained a lot of popularity in the Android world. On the server side though, Kotlin is not as broadly adopted, and some people still seem to be cautious when backend services are involved. Other developers are convinced that Kotlin is mature enough and can safely be used for any server application in which Java could play a role otherwise.

Students Build Electromagnetic Egg Drop Stand

See the original posting on Hackaday

The Egg Drop is a classic way to get students into engineering, fabrication, and experimentation. It’s a challenge to build a container to protect a raw egg from cracking when dropped from various heights.

Here’s a way to add some extra hardware to use when testing each entry. It’s an  electromagnetic drop stand built by several students along with [Tom Jenkins]. The stand doesn’t require anything too exotic, and it allows students to drop their eggs in a controlled manner for a fair competition. Along the way, they learn about circuits, electromagnets, and some other electronic concepts.

This DIY Turntable Just Got Freaky Fresh

See the original posting on Hackaday

Photography turntables are made for both the precise and lazy. Whether you are concerned about the precision of consistent angles during a photo shoot or you simply do not want to stand there rotating a plate after every picture — yes, it does get old — a lazy susan style automatic photography turntable is the ticket. This automatic 360° design made over at circuito.io satisfies both of these needs in an understated package. 

The parts required to make this DIY weekend project are about as minimal as they get. An Arduino Uno controls it all with a rotary encoder for …read more

A Few Caps For A Faster Multimeter

See the original posting on Hackaday

We just love it when someone takes apart a bench instrument. There is something about voiding a warranty and then making modifications that hits the spot and in a series of simple modifications, [Jack Zimmermann] dives into the guts if an Aneng AN8008.

The multimeter in question, the AN8008, is a low-cost true-RMS instrument that takes a bit longer to settle on the correct voltage reading than [Jack] would have liked. While poking around, he found that the DC rail inside the meter was host to noise spikes. He theorized that these were being coupled back from an element and …read more

The Super NES Classic is back at Best Buy on Saturday in limited quantities

See the original posting on The Verge

Since its initial release in late September, it hasn’t been easy to get a hold of the Super NES Classic, a miniature version of the beloved 1990s Nintendo console that comes loaded with 21 games. The initial preorders were available only to customers who happened to be awake in the wee hours of the morning, and despite Nintendo’s promises to manufacture “significantly more” stock than they did of the NES Classic, the $79.99 retro console sold out quickly in stores.

But this Black Friday weekend comes with a sliver of hope for SNES fans who have been deprived of this tiny nugget of nostalgia, or at least fans in driving distance of a Best Buy. The retailer has announced it has limited quantities of the SNES Classic, which will go on sale…

Approaching e-commerce investments in the age of Amazon

See the original posting on TechCrunch

 With Amazon as the 800-pound gorilla, many of my fellow investors choose to ignore e-commerce altogether. In fact, the industry hit recent lows in a number of deals and investments. But as Bonobos’ $310 million acquisition by Walmart and Stitch Fix’s IPO demonstrate, there are still plenty of exciting opportunities in this space for investors. Read More

Five Reasons Why You Should Use a Git-Based CMS (Part 3 of 5)

See the original posting on DZone Python

Most CMS technologies are what we would call a "coupled CMS." The content authoring and content delivery environments are usually part of the same stack. The act of "going live" with new content or a feature is essentially based on the act of marking a true/false in a database field. There are a lot of problems with coupled CMS platforms around security, performance, scalability, and flexibility (you can learn more here.)

For these reasons and many others, Crafter CMS is built as a decoupled CMS. With a decoupled CMS you author content in one system and publish to another separate system. For platforms like Crafter CMS that are decoupled, when correctly implemented, the architecture provides great solutions for the issues mentioned above. That said, nothing is without its challenges. Decoupled systems, by their nature, are typically very scalable and can have many instances all over the world. Security, scalability, and distribution are no longer issues that only concern the Internet’s biggest players like Google and Amazon. Security and distribution impact customer experience, safety and help reduce operating costs. Every brand-conscious and customer-forward organization in the world is focused on these tactical issues.

Modder puts Computer inside a Power Supply

See the original posting on Hackaday

When building a custom computer rig, most people put the SMPS power supply inside the computer case. [James] a.k.a [Aibohphobia] a.k.a [fearofpalindromes] turned it inside out, and built the STX160.0 – a full-fledged gaming computer stuffed inside a ATX power supply enclosure. While Small Form Factor (SFF) computers are nothing new, his build packs a powerful punch in a small enclosure and is a great example of computer modding, hacker ingenuity and engineering. The finished computer uses a Mini-ITX form factor motherboard with Intel i5 6500T quad-core 2.2GHz processor, EVGA GTX 1060 SC graphics card, 16GB DDR4 RAM, 250GB SSD, …read more

On today’s special live Vergecast, we’re thankful for the internet

See the original posting on The Verge

When I split the wishbone yesterday, I wished for a very special live Vergecast with my two good friends, Nilay Patel and Dieter Bohn. And now my wish has come true! We’re broadcasting live on YouTube right now. If for any reason we aren’t live right now, you already missed it, or Google Hangouts is broken in some terrible way.

Guess what we’re talking about!

At some point in the near future we’ll take the audio from the stream and put it into the regular podcast feed, so don’t worry too much if you miss out!

Black Eyed Peas’ graphic novel, ‘Masters of the Sun,’ gets the AR treatment

See the original posting on TechCrunch

 Black Eyed Peas frontman will.i.am took heed of Steve Jobs’ “think different” but perhaps more so, he has kept it all the way 100 by being fresh and original — the core values of golden-age hip-hop. Today, the group released an augmented reality app, available on iOS and Android, to go with its graphic novel Masters of the Sun: The Zombie Chronicles. The story,… Read More

UK authors and librarians’ open letter to Education Secretary: stop closing school libraries!

See the original posting on Boing Boing

I remember the day I realised that my daughter’s London school had no library, the shock I felt, the sense that the cuts had gone beyond the bone, and that kids were being deprived of something critical — and then the discovery that then-Education Minister Michael Gove was planning to spend a fortune distributing Bibles to schoolchildren with his name embossed in metal foil on the cover.
