Deep code search

Deep code search Gu et al., ICSE’18

The problem with searching for code is that the query, e.g. “read an object from xml,” doesn’t look very much like the source code snippets that are the intended results, e.g.:

*

That’s why we have Stack Overflow! Stack Overflow can help with ‘how to’ style queries, but it can’t help with searches inside codebases you care about. For example, “where in this codebase are events queued on a thread?”

…an effective code search engine should be able to understand the semantic meanings of natural language queries and source code in order to improve the accuracy of code search.

DeepCS is just such a search engine for code, based on the CODEnn (Code-Description Embedding Neural Network) network model. During training, it takes code snippets (methods) and corresponding natural language descriptions (from the method comments) and learns a joint-embedding. I.e., it learns embeddings such that a method description and its corresponding code snippet are both mapped to a similar point in the same shared embedding space. Then given a natural language query, it can embed the query in vector space and look for nearby code snippets. Compared Continue reading

Intel Opens Up About Next Generation Omni-Path Interconnect

If everything had played out as planned, then the original “Aurora” supercomputer planned by Intel and built by Cray for Argonne National Laboratory under contract from the US Department of Energy would probably have been at or near the top of the Top 500 charts this week at the International Supercomputing 2018 conference in Frankfurt, Germany. …

The value-add of NSX Data Center Compared To Open Source Solutions For Cloud Native Apps

In our job as System engineers in the networking and security for Cloud native applications (CNA) space we get to work with many customers on their implementation of CNA platforms. The fun part of that is that we get to hear the “DevOps” drivers and needs of many enterprise customers. Developers using CNA platforms such as Kubernetes (k8s) and Pivotal Application Service (Formerly known as PCF) don’t always have security and networking first in mind; they are focused on speed and innovation. A developer doesn’t want to wait for the networking team to provision service (e.g. load balancing, switching, etc.), or for the security team to whitelist a new app capability. This is especially true in enterprises where “Change management” is manual and long process. On the other hand, when it comes to those same enterprises, there are regulations and security requirements that can slow down the innovation process. To strike a balance, networking and security platforms for CNA need to operate in as seamless a manner as possible to maximize speed and efficiency for both IT and developers. NSX Data Center is a platform built just for Continue reading

Copyright? Copywrong!

Copyright? Copywrong!

The drafting of the new EU Copyright Directive was never going to be an easy task. As has been seen over the years, policy discussions involving digital service providers and the intellectual property rights community are often polarizing, and middle ground can be difficult to find. However, the existing legal framework – which dates from 2001 - needed a refresh, in order to take account of the new online environment in which user-generated content is a key feature, while acknowledging the challenges that authors face and their need for fair remuneration.

Unfortunately, as is now so often the case in Brussels, the new law is being drafted with a small set of large Internet companies in mind. This blinkered approach to rule-making frequently results in unintended and negative consequences for other parts of the Internet ecosystem, and indeed for end users, many of whom are often unaware that such policies are being created.

Monitoring and Filtering User-Generated Content - A Flawed Approach

The draft copyright proposal has been undergoing EU Parliamentary and Council scrutiny since it was tabled by the European Commission in 2016, and it has been heavily criticised by civil society organisations, numerous industry associations, renowned academics and Continue reading

BrandPost: WaveLogic Ai: Laying the Foundation for the Adaptive Network

Today’s networking challenges Network operators know it all too well: Streaming video, cloud computing, the Internet of Things (IoT), and the evolution to 5G are putting massive pressure on today’s networks, requiring capacity increases by orders of magnitude and the ability to respond to even greater unpredictability in traffic patterns.The optical network sits at the heart of communications, interconnecting people, data centers, and an increasing number of devices across any distance, from across the street to across the ocean. Yet, for all the critical functions and agility they need to provide to meet today’s web-scale demands, most networks are weighed down with manual processes and hardware inflexibility.To read this article in full, please click here

Network Break 190: Aruba Joins SD-WAN Party; Cisco Buys Into WiFi Location Services

Take a Network Break! Aruba Networks rolls out a new SD-WAN platform plus a grand strategy for branch management, Cisco acquires July Systems for its wireless location services technology, and AT&T sells dozens of data centers for $1.1 billion.

But AT&T may take that cash and pour it into the acquisition of a digital ad exchange company, Deutsche Telecom announces big layoffs in its T-Systems unit, and Australian telco Telstra splits off its legacy infrastructure unit into a standalone business.

A Web Application Firewall (WAF) vendor lifts the curtain on why WAFs get bought but rarely used, HPE pledges $4 billion for edge computing, and Intel bids a terse goodbye to its CEO.

ThousandEyes provides data, visualization tools for multi-cloud environments

For most businesses, the decision of “to cloud or not to cloud” has been answered with a resounding yes. The burning question now is which cloud provider to use, and that has no easy answer because every cloud provider has different pricing models and strengths and weaknesses.The reality is that almost every business of any significant size will embrace the concept of multi-cloud where a combination of Microsoft Azure, Amazon Web Services (AWS), Google Cloud Platform (GCP), and others are used.Multi-cloud rapidly becomes the norm Several factors are driving companies to multi-cloud — some business related and others technical that will continue to force this architecture upon companies. Pricing considerations and avoiding being beholden to a single vendor are a couple of issues that business leaders might be concerned with, whereas tools, innovation and functionality are factors that developers and IT individuals would prioritize when making a choice.To read this article in full, please click here
