Unity Editor for Linux

Unity Editor for Linux

A growing number of developers using the experimental version, combined with the increasing demand of Unity users in the Film and Automotive, Transportation, and Manufacturing (ATM) industries means that we now plan to officially support the Unity Editor for Linux. Currently, it’s available in preview, and we’re interested in gathering your feedback on our Unity Editor for Linux forum. We can’t wait to hear what you think on our Unity Editor for Linux forum.

Show HN: Real-Time Video Analytics with Redis

Show HN: Real-Time Video Analytics with Redis

Given this input video, the final output looks something like this:

This project demonstrates a possible deployment of the RedisEdge stack that provides real-time analytics of video streams. Put differently, you need to provide the RedisEdge server and a video stream. Both the top tool and the Grafana UI provide the following performance metrics:

Metrics sampled by capturing the Count’s video and using the application’s top tool:

The application’s rendered video stream (server.py) should be at Docker Compose setup also comes with a pre-provisioned Grafana server – it should be at http://localhost:3000/ (admin/admin).

From EDSAC to Raspberry Pi: 75 years of “computers that work” (2013)

From EDSAC to Raspberry Pi: 75 years of “computers that work” (2013)

It was where EDSAC, the first programmable computer ever brought into general service, was built, and where microprogramming was pioneered by Maurice Wilkes, the Lab’s second Director, using EDSAC 2. As the progress of computing technology accelerated, computers became less expensive, more compact, easier to user and, ultimately, ubiquitous, Wilkes’ response was to take the Lab in new directions, still guided by the ethos of innovating to solve problems, but ensuring practical usability as an outcome. By the time it reached its second iteration, the System had linked up 50 different computers and was so successful that members of the Lab preferred to use it for their research projects, rather than rely on the mainframe.

Watsi is hiring a software engineer

Watsi is hiring a software engineer

We’re hiring a Software Engineer to help us develop Meso – a suite of mobile and web applications that streamline the core components required to run any national health insurance system. At Watsi, the code we write directly impacts people’s health by helping governments and health providers digitally administer health insurance nationally and transparently. You’ll travel to East Africa 2 – 3 times a year (sometimes for 1 – 2 weeks at a time) to develop technologies alongside the local health facilities and insurance agencies that will use them.

Space firm founded by billionaire Paul Allen closing operations

Space firm founded by billionaire Paul Allen closing operations

SEATTLE/ORLANDO, Fla. (Reuters) – Stratolaunch Systems Corporation, the space company founded by late billionaire and Microsoft Corp co-founder Paul Allen, is closing operations, cutting short ambitious plans to challenge traditional aerospace companies in a new “space race,” four people familiar with the matter said on Friday. The company, a unit of Allen’s privately held investment vehicle Vulcan Inc, had been developing a portfolio of launch vehicles including the world’s largest airplane by wingspan to launch satellites and eventually humans into space. tinyurl.com/y6qp8bch

In January, three months after Allen’s death, Stratolaunch said it was scrapping the rocket-building portion of the company but would continue to focus on its carrier plane.

Apple Is Finally Killing iTunes

Apple Is Finally Killing iTunes

The move, which has been rumored for years now, will align Apple’s media strategy across the board: iPhones and iPads already offer separate Music, TV and Podcast apps in lieu of the centralized iTunes app that lives on Macs and Macbooks. Users can expect the new Music app to offer some of the same functionalities that iTunes currently does — such as purchasing songs and syncing phones — just with a sleeker interface that’s free of the outdated and oft-bemoaned features of the heritage product, and more closely bundled with streaming service Apple Music. By portioning out its music, television and podcast offerings into three separate platforms, Apple will pointedly draw attention to itself as a multifaceted entertainment services provider, no longer as a hardware company that happens to sell entertainment through one of its many apps.

A NY School District Defies State, Plans To Proceed With Facial Recognition Test

A NY School District Defies State, Plans To Proceed With Facial Recognition Test

A New York school district will move forward with its facial recognition pilot program next week, despite an explicit order from the New York State Education Department that it must wait until a standard is finalized for data privacy and security for all state educational agencies. Two hours after this story published, JP O’Hare, a representative of the New York State Education Department, said in an email, “The district has assured us no facial recognition software will be used next week while it tests other components of the system.” Lockport implied that its facial recognition system should not be a privacy concern because it “does not compile information on and track the movements of all District students, staff and visitors.”

Interview with Reid Hoffman

Interview with Reid Hoffman

So I did a summer internship at Xerox Park, where my job was building a simulator for a multiagent learning system. But the thing that I learned from philosophy was an ability to articulate theories crisply, which led to an ability to express crisp theories of human nature, which aligns with some of the most interesting things around , like consumer internet and entrepreneurship. But understanding — here is the way the world could be, here is the theory of human nature that you’re playing into in order to create that world, and here is that kind of combination of psychology, sociology and economics together with what’s possible in technology — that combination was enabled much more by philosophical thinking.

Implementing a Convolutional Neural Network Using Only NumPy

Implementing a Convolutional Neural Network Using Only NumPy

Consider this forward phase for a Max Pooling layer:

An example forward phase that transforms a 4×4 input to a 2×2 output

The backward phase of that same layer would look like this:

An example backward phase that transforms a 2×2 gradient to a 4×4 gradient

Each gradient value is assigned to where the original max value was, and every other value is zero. The forward phase caching is simple:

We’re primarily interested in the loss gradient for the filters in our conv layer, since we need that to update our filter weights. Doing the math confirms this:

We can put it all together to find the loss gradient for specific filter weights:

We’re ready to implement backprop for our conv layer!

New Social Media Question on DS-160 and DS-260 Visa Applications

New Social Media Question on DS-160 and DS-260 Visa Applications

Following the 2017 Presidential Memorandum, the Department of State had published a notice in the Federal Register last year explaining its plans to add several additional questions for nonimmigrant visa applicants, including a question listing multiple social media platforms and requiring the applicant to provide any identifiers (handles) used by applicants for those platforms during the five years preceding the date of application. Initially, the Department of State began using a supplemental questionnaire, Form DS-5535, requiring only some visa applicants who have been flagged for further review to provide their social media information. Department of State consular officers will use the information collected in the visa adjudication process with partner U.S. government agencies to determine certain applicants’ eligibility for a visa under existing statutory grounds of inadmissibility, so as to more rigorously evaluate the security and related visa ineligibilities.
