John Carmack On Modern C++
Winter break homework from John Carmack. Gamasutra reprint article "In-depth: Functional programming in C++":
A large fraction of the flaws in software development are due to programmers not fully understanding all the possible states their code may execute in. In a multithreaded environment, the lack of understanding and the resulting problems are greatly amplified, almost to the point of panic if you are paying attention. Programming in a functional style makes the state presented to your code explicit, which makes it much easier to reason about, and, in a completely pure system, makes thread race conditions impossible...

Modern C++ doesn’t imply necessarly the overuse of templates
Andrei Alexandrescu says about the Modern C++ design:
"Modern C++ Design defines and systematically uses generic components - highly flexible design artifacts that are mixable and matchable to obtain rich behaviors with a small, orthogonal body of code."
Modern C++ has a close relation with generic programming; probably it’s the reason that makes many developers neglect the modern C++ approach. They think that the code will be mostly implemented as templates, which makes the code difficult to read and maintain.
In the SDK, the templates represent only 20% of all types defined and most of them are related to the technical layer... ( full article )
Interview with David Sands, ST Robotics International
We call our robots entry level for a very good reason. People can get started so easily with our robots. They are not the best robot arms on the planet but they are affordable and incredibly easy to use.
Kissing It Better: Lifting Ergonomically with Vacuum
By using the right suction and the right lips for the job, you really can "kiss it better" before lifting, rather than after.
OpenCV Vision Challenge
From the OpenCV Foundation:
OpenCV Foundation with support from DARPA and Intel Corporation are launching a community-wide challenge to update and extend the OpenCV library with state-of-art algorithms. An award pool of $50,000 is provided to reward submitters of the best performing algorithms in the following 11 CV application areas: (1) image segmentation, (2) image registration, (3) human pose estimation, (4) SLAM, (5) multi-view stereo matching, (6) object recognition, (7) face recognition, (8) gesture recognition, (9) action recognition, (10) text recognition, (11) tracking.
Conditions:
The OpenCV Vision Challenge Committee will judge up to five best entries.
You may submit a new algorithm developed by yourself or your implementation of an existing algorithm even if you are not the author of the algorithm.
You may enter any number of categories.
If your entry wins the contest you will be awarded $1K.
To win an additional $7.5 to $9K, you must contribute the source code as an OpenCV pull request under a BSD license.
You acknowledge that your contributed code may be included, with your copyright, in OpenCV.
You may explicitly enter code for any work you have submitted to CVPR 2015 or its workshops. We will not unveil it until after CVPR.
Timeline:
Submission Period: Now – May 8th 2015
Winners Announcement: June 8th 2015 at CVPR 2015

Robotic Assembly
Manual assembly procedures, which previously have been neither ergonomic nor appropriate for automation, can currently be automated in a cost-effective way.
Deep Visual-Semantic Alignments for Generating Image Descriptions
Because of the Nov. 14th submission deadline for this years IEEE Conference on Computer Vision and Pattern Recognition (CVPR) several big image-recognition papers are coming out this week:
From Andrej Karpathy and Li Fei-Fei of Stanford:
We present a model that generates free-form natural language descriptions of image regions. Our model leverages datasets of images and their sentence descriptions to learn about the inter-modal correspondences between text and visual data. Our approach is based on a novel combination of Convolutional Neural Networks over image regions, bidirectional Recurrent Neural Networks over sentences, and a structured objective that aligns the two modalities through a multimodal embedding. We then describe a Recurrent Neural Network architecture that uses the inferred alignments to learn to generate novel descriptions of image regions. We demonstrate the effectiveness of our alignment model with ranking experiments on Flickr8K, Flickr30K and COCO datasets, where we substantially improve on the state of the art. We then show that the sentences created by our generative model outperform retrieval baselines on the three aforementioned datasets and a new dataset of region-level annotations...

Boston Magazine Profiles Rodney Brooks of Rethink
Long article about Rodney Brooks co-founder of Rethink and former CTO at iRobot:
...Brooks cofounded the bedford-based iRobot in 1990, and his motivation, he explains, had something to do with vanity: “My thoughts on my self-image at the time was that I didn’t really want to be remembered for building insects.” Then he pauses for a moment and laughs. “But after that I started building vacuum-cleaning robots. And now there is a research group using Baxter to open stool samples. So now it’s shit-handling robots. I think maybe I should have quit while I was ahead. You know, that’s something no one ever says: ‘I hope my kid grows up to open stool samples... ( full article )
