If you use React. JS and agreed to its license, and you decide to sue Facebook for patent issues, you are no longer allowed to use React. JS or any Facebook software released under this license. It was the first widely-adopted open source distributed computing platform. But some geeks running it are telling Datanami that Hadoop "is great if you're a data scientist who knows how to code in MapReduce or Pig It's sort of as simple as that," says Bob Muglia, CEO of Snowflake Computing, which develops and runs a cloud-based relational data warehouse offering.

That may be a little strong," Johnson says. But it's ill-suited for running interactive, user-facing applications You really have to understand how this thing works to get what you want. That feels like a better unifying principal Orome1 quotes a report from Help Net Security: A critical vulnerability in Apache Struts 2 is being actively and heavily exploited , even though the patch for it has been released on Monday.

It allows attackers to include code in the "Content-Type" header of an HTTP request, so that it is executed by the web server. Almost concurrently with the release of the security update that plugs the hole, a Metasploit module for targeting it has been made available. Unfortunately, the vulnerability can be easily exploited as it requires no authentication, and two very reliable exploits have already been published online. Also, vulnerable servers are easy to discover through simple web scanning.

WebKit's bug-tracker now includes a comment from Friday noting " the bots all are red " on their git-svn mirror site, reporting an error message about a checksum mismatch for shattered The reason to upload the files was to create a test for checking cache poisoning in WebKit.

Another news story is that based on the theoretical incomplete description of the SHA-1 collision attack published by Google just two days ago, people have managed to recreate the attack in practice and now you can download a Python script which can create a new PDF file with the same SHA-1 hashsum using your input PDF.

The attack is also implemented as a website which can prepare two PDF files with different JPEG images which will result in the same hash sum. Open sourced in , the Apache Kafka distributed streaming platform is now used at more than a third of Fortune companies as well as seven of the world's top 10 banks.

The legacy systems couldn't help us anymore. If the product experience is tailored to ensure that the developers are successful and the technology plays a critical role in your business, you have the foundational pieces of building a growing and profitable business around an open-source technology Kafka is used as the source-of-truth pipeline carrying critical data that businesses rely on for real-time decision-making.

Now that TrendMicro owns TippingPoint, there'll be "more targets and more prize money" according to eWeek, and something special for Pwn2Own's 10th anniversary in March. Slashdot reader darthcamaro writes: For the first time in its ten-year history, the annual Pwn2Own hacking competition is taking direct aim at Linux. Pwn2Own in the past has typically focused mostly on web browsers, running on Windows and macOS.

Moving NetBeans to a neutral venue like Apache, with its strong governance model, would help the project attract more contributions from various organizations, according to the proposal posted in the Apache wiki.

While Oracle will relinquish its control over NetBeans under the proposal, individual contributors from Oracle are expected to continue contributing to the project.

On Facebook, Gosling posted the proposal meant "folks like me can more easily contribute to our favorite IDE. The finest IDE in existence will be getting even better, faster! I'm thrilled that the NetBeans community will now be able to chart its own course.

Reader JImbob0i0 writes: After almost another year without a release and another major CVE leaving users vulnerable for that year the Chairman of the Project Management Committee has started public discussions on what it will entail to retire the project, following the Apache Board showing concern at the poor showing.

It's been a long battle which would have been avoided if Oracle had not been so petty. Did this behaviour actually help get momentum in the community underway though? What ifs are always hard to properly answer. Hopefully this long drawn out death rattle will finally come to a close and the wounds with LibreOffice can heal with the last few contributors to AOO joining the rest of the community.

The two projects were selected following a public survey that included several open-source projects deemed important for both the EU agencies and the wide public.

The actual security audit will be carried out by employees of the IT departments at the European Commission and the European Parliament. This is only a test pilot program that's funded until the end of the year, but the EU said it would be looking for funding to continue it past its expiration date in December An anonymous reader writes: Cloud computing startup Mesosphere has opted to open-source its data center management platform.

The three-year-old San Francisco company's datacenter operating system DCOS was built as an operating system for all services in a data center to function as one pool of resources. Capabilities include the quick, app store-like installation of more than 20 complex distributed systems, including HDFS, Apache Spark, Apache Kafka and Apache Cassandra, Mesosphere said in an announcement. Although some of the company's technologies were already available as open source, others were propriety until now.

Mesosphere said it welcomes additional enterprises interested in partnering on this open source project. Wired has more details on this in its slightly enthusiastic report titled You want to build an empire like Google's?

This is your OS. With this release comes enhancements and improvements. The project allows creation and manipulation of PDF documents, and the ability to extract content from them. Support for forms in open-source PDF viewers is currently disappointing, and I hope this heralds improvement on that front. Patrick O'Neill writes: A common configuration mistake in Apache, the most popular Web server software in the world, can allow anyone to look behind the curtains on a hidden server to see everything from total traffic to active HTTP requests.

When an hidden service reveals the HTTP requests, it's revealing every file—a Web page, picture, movie,. Tor's developers were aware of the issue as early as last year but decided against sending out an advisory. The problem is common enough that even Tor's own developers have made the exact same mistake. Until October , the machine that welcomed new users to the Tor network and checked if they were running up-to-date software allowed anyone to look at total traffic and watch all the requests.

An anonymous reader writes: You may have heard recently of the Remix OS , a fork of Android that targets desktop computing. The operating system, which was created by former Google employees and features a traditional desktop layout in addition to the ability to run Android apps, was previewed on Ars Technica a few weeks ago, but it was not actually released for end-users to download until earlier this week. Additionally, browsing through the install image files reveals that the operating system is based on the Apache Licensed Android-x86 project.

From the article: "Output is absolutely clear — no differences! No authors, no changed files, no trademarks, just copy-paste development. However, Hadoop has had a less than stellar six months, beginning with the lackluster Hortonworks IPO last December and the security concerns raised by some analysts.

Another survey records only a quarter of big data decision makers actively considering Hadoop. With rival Apache Spark on the rise, is Hadoop being bypassed in big data solutions? Qbertino writes I've been a linux user for more than 15 years now and in the last ten I've done basically all my non-trivial web development on Linux.

It models several generally applicable aspects of a decision support system, including queries and data maintenance.

Please note this is mostly a single connection benchmark run on one computer, with many very simple operations running against the database. The Transaction Processing Performance Council TPC is a non-pro t corporation founded to de ne vendor-neutral transaction processing benchmarks and to disseminate ob-jective, veri able performance data to the industry.

In this paper the author shows how the TPC model for developing and maintaining benchmarks can be applied to creating the first industry standard benchmark on Big Data. Built for Speed. The TPC-H benchmark is a decision-support benchmark. See how SQL Data Warehouse outperforms other cloud providers as a scalable, highly performant, analytical cloud solution at an unmatched performance and value based on the industry-standard TPC-H benchmark.

They can provide useful insight into the creation of a big data benchmark. This standardised measurement is TPC-DS is an industry standard when it comes to measuring performance across data analytics tools and databases in general. MySQL 5. Env: Spark 2. The demo and results shown are not official TPC benchmark results and all testing was done with a workload derived from the TPC-C benchmark.

RDM Performance Benchmarks. The TPC is introducing V3. The MR3 release includes scripts for helping the user to test Hive on MR3 using the TPC-DS benchmark, which is the de-facto industry standard benchmark for measuring the performance of big data systems such as Hive.

It consists of a suite of business-oriented ad-hoc queries and concurrent data modifications. It features both a query and transaction workload in separate configuration files. View the Benchmark setup instructions and configuration details ». In order to derive performance evaluations of practical relevance to the end users, the application system including the database system has to be benchmarked.
