Google AI Blog: Grasp2Vec: Learning Object Representations from Self-Supervised Grasping
Conclusion
In our paper, we show how robotic grasping skills can generate the data used for learning object-centric representations. We then can use representation learning to “bootstrap” more complex skills like instance grasping, all while retaining the self-supervised learning properties of our autonomous grasping system.

Besides our own work, a number of recent papers have also studied how self-supervised interaction can be used to acquire representations, by grasping, pushing, and otherwise manipulating objects in the environment. Going forward, we are excited not only for what machine learning can bring to robotics by way of better perception and control, but also what robotics can bring to machine learning in new paradigms of self-supervision.

The multi-mesh vision, and how SuperGloo will bring it to life
The vision: multi-mesh
We at Solo believe that in the near future, many companies will find themselves working with multiple instances of service mesh, and that in many cases this will involve several different service mesh implementations. Possible multi-mesh scenarios include:

Different groups within the same organization may favor different service mesh offerings, which best fit their specific needs.
Users may find that one service mesh works better for their on prem workloads, while another mesh is a better fit for their public cloud services.
Users who work with a multi-cloud may, for example, prefer to work with the AWS App mesh for their services that run on the AWS cloud (where this service is offered free of charge), but use Managed Istio for the ones that run on the Google cloud.
Users that select — for some reason — to migrate from one service mesh implementation to another may transiently work simultaneously with the ‘old’ and ‘new’ mesh.

Awesome Vulcan
This application is an awesome demo of the equally awesome JavaScript framework Vulcan.js. The functionnalities are fairly limited for the moment, however the underlying code has been built with reusability in mind.
It could serve as basis or an inspiration for your own application, especially if you want to build an admin dashboard, an item catalog or any other kind of backoffice application. Thus, it gave birth to a few generic packages:

Who-T: Understanding HID report descriptors
As said above, the purpose of HID is to make devices describe themselves in a generic manner so that you can have a single driver handle any input device. The idea is that the host parses that standard protocol and knows exactly how the device will behave. This has worked out great, we only have around 200 files dealing with vendor- and hardware-specific HID quirks as of v4.20.

HID messages are Reports. And to know what a Report means and how to interpret it, you need a Report Descriptor. That Report Descriptor is static and contains a series of bytes detailing "what" and "where", i.e. what a sequence of bits represents and where to find those bits in the Report. So let's try and parse one of Report Descriptors, let's say for a fictional mouse with a few buttons. How exciting, we're at the forefront of innovation here.

The Report Descriptor consists of a bunch of Items. A parser reads the next Item, processes the information within and moves on. Items are small (1 byte header, 0-4 bytes payload) and generally only apply exactly one tiny little bit of information. You need to accumulate several items to build up enough information to actually know what's happening.

The fastest production-ready image resize out there, part 0
Pillow is an image processing library for Python maintained by the community headed by Alex Clark and Eric Soroos . The lib was already being used by Uploadcare when I became a part of the team. At first, it seemed pretty surprising, why use a language-dependent library for such a critical task like image processing? Wouldn’t it be better to go with ImageMagick or something? Currently, I’d say Pillow was a good idea because Pillow and ImageMagick had quite the same performance, while it’d take way more time and effort to optimize resize for the latter.

Elastic doubles down on cloud native with Helm charts and CNCF membership | Elastic
Announcing Helm charts for Elasticsearch and Kibana

We are excited to announce the initial public alpha of our Elasticsearch and Kibana Helm charts. These charts make it incredibly simple to deploy Elasticsearch and Kibana to Kubernetes in a manner of minutes.

As Kubernetes has continued to mature, the ability to effectively run stateful workloads has finally started become a reality. With this foundation in place, the timing was right for us to create these Helm charts as a way to help enable our users to run the Elastic Stack using modern, cloud-native deployment models and technologies.

Helm (an open source, CNCF-maintained project) is often touted as the missing package manager for Kubernetes. Helm charts are rapidly becoming a standard way of creating, publishing, and sharing Kubernetes applications. We love them because they provide a great way for us to package and share best practices and default configuration alongside our software.

Transforming efficiency with LoRa technology - Electronic Products
When a radical technology enters the market, designers look at how it can transform the world. For LoRa devices and wireless radio frequency technology (LoRa Technology), this has meant that its long range and low power consumption can significantly simplify network design by enabling greater reach with less infrastructure and cost.

The advantages offered by the technology’s wireless communication are significant compared to alternative options. Its robust penetration reaches up to 2 miles in dense urban areas and offers an outdoor line of sight (LOS) up to 30 miles in remote rural landscapes. Operating on an open standard, LoRa can be used with LoRaWAN, IEEE 802.15.4g, and WMBus protocols and provides footprint-compatible ICs to support global coverage.

LoRaWAN-based sensors and gateways (base stations) typically cost less than competing low-power wide-area network (LPWAN) technologies for a number of reasons. First, there are no wireless spectrum license fees because they operate in the unlicensed spectrum. Cellular-based technologies operate in licensed spectrum and incur intellectual property (IP) royalties due to 3GPP heritage.

On self-publishing “A Programmer’s Introduction to Mathematics”
Over the past four years I’ve been writing a book, A Programmer’s Introduction to Mathematics. It teaches someone with programming knowledge and experience how to engage with mathematics. I can achieve this goal largely because of the implicit overlap in the content and ways of thinking between math and programming. Despite that, there is no smooth bridge from one world to the other—a bridge that explains the unfamiliar parts and focuses on the important concepts, while leveraging programming to demonstrate applications.
Until now. If you’re a programmer who wants to really grok math, this book is for you.
In this article I’ll explain how I wrote and self-published the book.

Setting up a new (or repurposed) Mac: 3 Manual migration – The Eclectic Light Company
Manual migration boils down to you copying, in the Finder, at the command line, or by running scripts, files from your old Mac to your new one. There is no single way to do this: you get to choose exactly what you migrate, and how you do it. I cannot, therefore, suggest any best way to do it. What I will do, though, is point out solutions to some of the pitfalls and problems which you may encounter.

Clone no more

One once-wonderful solution of migrating by cloning is almost certainly now doomed to fail. In this, you cloned your old Mac’s startup volume to become the startup volume for your new Mac. This was usually performed using an external disk as an intermediary, with software such as Carbon Copy Cloner or SuperDuper.

FireHOL is a language (and a program to run it) which builds secure, stateful firewalls from easy to understand, human-readable configurations. The configurations stay readable even for very complex setups.

FireQOS is a program which sets up traffic shaping from an easy-to-understand and flexible configuration file.

Both programs abstract away the differences between IPv4 and IPv6. so you can concentrate on the rules you want. You can apply rules for IPv4 or IPv6, or both, as you need.

We think the best advert for these programs are their configurations. See below for:

Leave Gmail in 10 steps – Adrien Di Pasquale Blog
Step 1 : Get a new mail address and provider

First, I strongly suggest you buy a domain name, so that you really own your mail address, and don’t depend on any service. You can purchase one at Gandi.

From there on, you could use Gandi’s mail servers, but I recommend you use Fastmail’s. It’s not free, but it will be much simpler to setup, faster, they provide push notifications for mobile, their spam filter is better, their web interface is better, and it’s the most popular privacy-respecting service.

Signing up with Fastmail is very simple. If you bought a domain name, you can use their easy-setup option where you use their name servers and they do all the hardlifting. You will still be able to add custom DNS entries later if you want to, for your personal website or blog. If you did not buy a domain name, you can also create a mail address ending with one of theirs : sent.com, fastmail.com…

The Swiss Army Knife of Hashmaps | Arrow of Code
A while back, there was a discussion comparing the performance of using the hashbrown crate (based on Google’s SwissTable implementation1) in the Rust compiler. In the last RustFest, Amanieu was experimenting on integrating his crate into stdlib, which turned out to have some really promising results. As a result, it’s being planned to move the crate into stdlib.

While the integration is still ongoing, there’s currently no blog post out there explaining SwissTable at the moment. So, I thought I’d dig deeper into the Rust implementation to try and explain how its (almost) identical twin hashbrown::HashMap works.

Barefoot Networks may have built the world's fastest networking switch chip | Computerworld
As its name implies, PISA doesn’t force switches to use any existing protocol, including TCP/IP (Transfer Control Protocol/Internet Protocol), the basic mechanism of most current data networks. About all that’s required for it to work is to make what comes out of the ports look like Ethernet packets.

That makes Barefoot’s switch architecture more software-defined than anything that’s come out of SDN (software-defined networking) to date, Burke said. In a way, it’s a next step for SDN. Barefoot’s founder and chief scientist, Nick McKeown, was one of the founders of Nicira Networks, the pioneering SDN startup that was acquired by VMware in 2012.

Western Digital develops a new soft spot for the hyper-converged world – a software spot, that is • The Register
WD paints converged infrastructure as a simplification of servers, storage, and networking. Hyper-converged infrastructure integrates the hardware into combined pools of resources, yet generally prevents separate scaling of these three main components.

A software-based composable infrastructure disaggregates these components into separate resource pools that can be independently scaled up or down. Driven by applications and other code that talk via Western Digital's open Kingfish APIs, such a software composable infrastructure should also avoid supplier lock-in, it is claimed.

For WD, the SCI fabric is NVMe-over-fabrics, hence the D3000 having an NVMe-oF interface. The media tier will be, it says, an equal citizen in this SCI scheme It calls its API Kingfish, reckoning it’s a follow on from the Redfish server management and Swordfish storage management APIs. Kingfish provides physical and logical-virtual system management. We're told it builds on existing open standards, and that WD is contributing these APIs to the public domain to encourage innovation and market adoption.

What is a keychain?
The keychain in Mac OS X is Apple’s password management system.
A keychain can store all your passwords for applications, servers, and websites, or even sensitive information unrelated to your computer, such as credit card numbers or personal identification numbers (PINs) for bank accounts.
When you connect to a network server, open an email account, or access any password-protected item that is keychain-aware, your keychain can provide the password so you don't have to type it.
You start with a single keychain, which is created automatically the first time you log in to your Mac OS X user account. Your default keychain has the same password as your login password. This keychain is unlocked automatically when you log in to Mac OS X and is referred to in Keychain Access menus as the "login" keychain.

Apache Mesos
What is Mesos? A distributed systems kernel

Mesos is built using the same principles as the Linux kernel, only at a different level of abstraction. The Mesos
kernel runs on every machine and provides applications (e.g., Hadoop, Spark, Kafka, Elasticsearch) with API’s for
resource management and scheduling across entire datacenter and cloud environments.

Node.js for Embedded Systems
he book Node.js for embedded systems explores how a web technology can change the way we build hardware.

Compared to classical programming languages for embedded development, JavaScript embraces open-source collaboration and should help with a good "user" experience. Besides programming concepts, the book provides on overview on embedded hardware that support JavaScript.

At this website, you can find a summary of topics and ideas that are discussed in the book. Also, this website may act as reference or start for new projects. Please help to make the book and website better: Email Us

The Arcane Algorithm Archive

The Arcane Algorithm Archive is a collaborative effort to create a guide for all important algorithms in all languages. This goal is obviously too ambitious for a book of any size, but it is a great project to learn from and work on and will hopefully become an incredible resource for programmers in the future. The book can be found here: https://www.algorithm-archive.org/. The GitHub repository can be found here: https://github.com/algorithm-archivists/algorithm-archive. Most algorithms have been covered on the YouTube channel LeiosOS: https://www.youtube.com/user/LeiosOS and live coded on Twitch: https://www.twitch.tv/simuleios. If you would like to communicate more directly, please feel free to go to our discord: https://discord.gg/Pr2E9S6.

Note that this project is essentially a book about algorithms collaboratively written by an online community. Fortunately, there are a lot of algorithms out there, which means that there is a lot of content material available. Unfortunately, this means that we will probably never cover every algorithm ever created and instead need to focus on what the community sees as useful and necessary. That said, we'll still cover a few algorithms for fun that have very little, if any practical purpose.

What does the OS X Activity Monitor’s “Energy Impact” actually measure? | Nicholas Nethercote
However, despite its prominence, the exact meaning of the “Energy Impact” measure is unclear. In this blog post I use a combination of code inspection, measurements, and educated guesses to hypothesize how it is computed in Mac OS X 10.9 and 10.10.

What & Why · Reason
Reason is not a new language; it's a new syntax and toolchain powered by the battle-tested language, OCaml. Reason gives OCaml a familiar syntax geared toward JavaScript programmers, and caters to the existing NPM/Yarn workflow folks already know.

What makes ReasonML so great? – LogRocket
What exactly is Reason?
ReasonML is a syntax extension for the OCaml language created by Facebook. Rather than creating an entirely new language, the creators of Reason chose to build on top of OCaml, a battle-tested functional systems programming language that’s been around since the late 1990s.
In fact, Reason has the same roots as React (which needs zero introduction in the world of 2018 web development). Many of the initial React prototypes were done with language very similar to OCaml (Standard ML), and Reason and ReactJS share the same creator!
