Mobile development: ionic framework integrates vue

The Ionic development team has released Ionic Vue and sees it as an important milestone for the open source mobile app framework Ionic. The native Vue version is designed to help developers build progressive web apps for iOS, Android and the web. Vue 3, the third major version of the popular JavaScript framework, was recently released. Ionic Vue keeps support for the new features ready.

"Ionic for Everyone"

Ionic framework originally had mobile development with Angular.js in mind. But with version 4 the tool opened up for development with other frameworks. The release relies on a collection of web components with custom elements and Shadow DOM APIs that are available in any contemporary browser.

The Ionic team introduced the fourth major release of the framework in a blog post titled "Ionic for Everyone" ahead of. Ionic’s user interface controls are based on Web Component APIs that basically work with all rough front-end frameworks. However, since Ionic must additionally integrate a framework’s routing system to enable reliable navigation, Ionic still has to deliver functionality specific to that framework. In addition, developers expect certain things to work as they would with their preferred framework, rather than with standardized Web components. For the popular JavaScript frameworks React and Vue.js, Ionic has therefore released the special bindings.

Hp z2 mini g5: compact workstation with gaming potential

The American PC manufacturer HP has given the compact Z2 Mini workstation a makeover. It is now available with tenth generation Core-i processors with up to ten cores and a Quadro RTX 3000 (mobile) graphics card. This makes the Z2 Mini G5 suitable for rendering, image editing and office applications. Due to its small size, it can be mounted on the back of a monitor to save space.

If desired, the Z2 Mini G5 can fit behind a PC monitor.

Compared to the previous generation, GPU rendering performance is said to have tripled, according to HP. The manufacturer also promises an increase in 3D gaming performance by a factor of 2.5 compared to the Z2 Mini G4. At first glance, this seems unusual for a professional device, but according to HP, 34 percent of users also use their home office computer for games and private things.

Augmented reality: prehistoric animals and new cultural goods in google's catalog's catalog

A prehistoric crustacean in your own living room? Google promotes its Arts–Culture app with some new exhibits that can be projected into the surrounding environment via augmented reality. It is available for Android and iOS.

Animals or cultural heritage

As Google explains in its topic-specific blog, the company has digitized the body forms of prehistoric animals in collaboration with famous museums such as Moscow’s State Darwin Museum and London’s National History Museum. Some special animal exhibits, such as the skeleton of the largest living mammal on earth – the blue whale – have also made it into the collection.

The cat saw the prehistoric crustacean “Cambropachycope” of course not. They saw treats. The coarseness of the exhibits can be easily changed within the free app with a few swipes of the finger. (No animal was tortured for this photo)

Hadoop: apache impala 4.0 with extended multithreading

The Apache Software Foundation (ASF) has presented a new major release of Impala, the query engine tailored to Hadoop, with numerous bug fixes, as well as improvements and new features. Apache Impala uses the same metadata and SQL syntax as Apache Hive, and with the new version 4.0, provides users with enhanced multithreading options.0 now provides users with advanced multithreading options. In addition, the update brings some fundamental changes to authentication and authorization – for example, the departure of Sentry in favor of Ranger.

Multithreading for all queries

For analytical queries on data stored in HDFS (Hadoop Distributed File System), Kudu, or even in the cloud, Impala offers a different level of parallelism that can be specified via the MT_DOP option for all those operations that can benefit from multithreaded execution. Previously, however, this option was limited to queries involving only scans and aggregates. As of version 4.0, MT_DOP is now available for all queries.

After the original Impala developer Cloudera announced in the course of its merger with Hortonworks that it would phase out its own Sentry project for authorization and auditing purposes in favor of Apache Ranger contributed by Hortonworks, Impala 4.0 now takes the final step: support for Sentry is completely dropped. Although Ranger was not compatible with Impala at the time, its broader feature set and more strategically promising integration with Hadoop components clinched the deal.

Original stories and news with a traceable originator will be placed higher in Facebook’s news feeds in the future. To do this, the operator of the social network wants to look at several articles on a topic and smoke those that are most often cited as original sources. Initially, this will only be done with English-language messages, with other languages to follow later on.

This does not mean that news prioritized in this way will always float to the top of the newsfeed. Furthermore, most of the news in the newsfeed should come from sources that users themselves or their "friends" Facebook explains. If publishers share multiple news items and are visible in a user’s newsfeed, the "more original" to be given preference so that they are better distributed. The "original reporting" The ie is complex to figure out, so Facebook wants to "Continue to work with publishers and researchers to refine this approach over time".

Facebook under prere

Against the spread of fake news, Facebook has used fact checkers so far. "Community reviewers" The first step is for learning machines to track down potential misinformation and submit their preliminary verdict to the actual fact-checkers. Facebook is currently under prere because major advertisers have pulled out, at least temporarily, because too much hate is being spread on the social network.

More code security in open source: one year github security lab

As part of Universe 2019, GitHub had unveiled a new initiative to improve code security a year ago. GitHub Security Lab aims to help secure the open source ecosystem. The cooperation of all parties interested in secure software (developers, companies, security researchers) should be simplified and made more effective. Security Lab partners include Google, Uber, Mozilla and Oracle.

Security research, community and industry engagement

The initiative focuses on three key areas: Security research, community building and industry engagement. GitHub Security Lab is essentially a team of security researchers focused on finding vulnerabilities in open source software (OSS) before they become exploits – that is, before an attacker can exploit the vulnerability. GitHub states that the team has already found over 400 Ies in the first year through variant analysis driven by its own code analysis engine, CodeQL, targeted fuzzing and manual code review. Rough projects such as Google Chrome, Android, the Linux kernel, Ubuntu, and Java enterprise applications were also affected, it said.

The team also reportedly helped stop an active attack on an OSS supply chain. In addition, the initiative apparently recently helped identify and fix a critical remote vulnerability in the German COVID-19 infrastructure.

Mars drill instrument hp³ sunk entirely into the ground

The German HP³ drilling instrument brought back by NASA’s Insight spacecraft has meanwhile made its way so far into the soil of the Red Planet that it is completely covered by sand. In view of the extremely lengthy procedure used to reach this stage, those responsible have now decided to fill the pit dug in the process with sand to help the robot penetrate further. The procedure is complicated by dust storms that have covered the solar cells of the probe, which is why less electrical power is available, the German Aerospace Center now explained.

Difficult ground

Insight had landed on Mars in late 2018. On board it has the German-developed HP³ tool, which looks like a crude nail. It has a built-in hammer and drags a cable behind it that’s loaded with temperature sensors. It’s actually supposed to hammer its way down three to five meters and measure temperatures to within a thousandth of a degree Celsius. From this, it is possible to determine how the interior of the Red Planet has developed and whether it still has a bright, liquid core. But after the first hammer blows in March 2019, things soon went nowhere, and since then researchers have been trying to solve the unexpected problems the instrument encounters as it penetrates the ground.

By last fall, researchers had changed approaches and placed Insight’s robotic arm behind HP³ as a resistor. In a lengthy process of painstaking work, the instrument has thus succeeded in getting so far into the ground that it is now completely covered by sand, even though it is apparently no more than a centimeter deep, as DLR writes. A thermal conductivity metric will now be used to try to determine depth. Depending on that outcome, researchers then plan to fill in the small pit with the robotic arm to help HP³ dig in further. But that will now take quite a while, they write. HP³ would therefore not carry out new hammer blows until the beginning of 2021.

Climate change: earth's energy imbalance is getting stronger

The Earth has stored significantly more warmth than it has given off over the past 14 years. Between 2005 and 2019, the Earth’s energy imbalance nearly doubled, according to the U.S. National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA). This trend is mainly due to the fact that solar radiation is less reflected by clouds and sea ice. At the same time, long-wave radiation from Earth into space has decreased, in part because of more greenhouse gases, he said.

Human and natural factors combined to cause warming, leading to gross shift in Earth’s energy imbalance. The Ausmab is at spiellos, said the head of the study, Norman Loeb according to the release "The trends we have found are in some ways quite alarming."

NASA and NOAA researchers compared data from two independent sets: observations from the satellite-based Clouds and the Earth’s Radiant Energy System (CERES) and from the Argo ocean buoy fleet. Researchers studied changes in clouds, water vapor, trace gases and light output from the sun, surface albedo, aerosols and changes in surface and atmospheric temperature distribution. The data of both measuring systems showed rough agreement.

Oracle publishes machine learning library for java

Oracle has released Tribuo, a machine learning library for Java, open source under the Apache 2.0 License on GitHub. The library has its origin in the Oracle Labs Machine Learning Research Group and is probably already used for several years in production within Oracle.


The researchers want it to respond to the observation that coarse software systems want to use building blocks that describe themselves and know when their inputs or outputs are unsound. Most ML frameworks do not adequately address this requirement with their model processing, according to Oracle. Because most ML libraries expect a stack of float arrays to train a model.

Finally, researchers see the scenario that tracking models in production is also difficult because it requires external systems to maintain the link between a deployed model and the training process and data. For usual, the burden of these additional requirements falls on the teams that integrate ML libraries into their products or systems. It would probably be better to embed this task in the ML library itself.

Shift4me: automatic bicycle circuit with arduino

Many people don’t use their bike’s gears to the fullest and therefore ride slower or more uncomfortably than they should, believes bike fan Jan Oelbrandt. Therefore, the tinkerer has decided to create an automatic solution for switching, which really takes all the work off your hands. You only have to steer and pedal it yourself.

Its Shift4Me system weighs very little and can be built and installed by the user with basic electronics skills and access to a 3D printer. It should work with both derailleur and hub gears, as long as the gear is operated with a shift cable. Even electric veins can be equipped with it. Even the highest improvements can be achieved by automatic switching, saving battery power and reducing wear and tear, explains Oelbrandt.
