Physics laboratory in space

Einstein’s general relativity is amazingly durable – astrophysicists have now re-established with unprecedented precision

The physics laboratory, which michael kramer has chosen from the university of manchester and its domestic colleagues worldwide, is not tailored to public transport. Kramer will only be able to see his life from afar. And that’s a good thing, because the chance to survive on a neutron star, even in the optimistic case goes against zero. In addition, the arrival took unreasonably long – with lighting speed up to 2000 years. The study object, which the scientific team has chosen around kramer, is called psr j0737-3039. It was only three years ago discovered and is the first known star system, in which two pulses around each other.

That it is so well suited as a test laboratory for einstein’s general relativity (and in particular the detection of space-time crumminess caused by gravity, lies on the extreme conditions that prevail there. As special neutron stars have the two components of psr j0737-3039 despite about one and a half-fold solar masses only a diameter of 20 kilometers, they are superconducting and suprafluid and turn (at a distance, the approximately double earth moon distance corresponds) in just 2.4 hours around the common focus.

Eclipse microprofile improves connection to development environments

Eclipse MicroProfile improves connection to development environments

Around eclipse microprofile, two open source tools have been created that should simplify the development of applications with the specification designed above all on microservices. The language server for eclipse microprofile (lsp4mp) offers connection to the language server protocol, and the tools for microprofile provide a specific connection to microsoft’s source-off sourcecode editor visual studio code for the protocol.

Help for properties and java code

The lsp4mp relies on the language server protocol to offer an ideal integration of helps such as auto resistance and quick fixes. He offers for the microprofile config.Properties defined properties, among others, car resistance, help when driving over with the mouse (hover), display of definitions as well as validation and quick fixes.

Eclipse MicroProfile improves connection to development environments

Lsp4mp shows the associated microprofile documentation, inter alia, with the mouse overriding properties with the mouse.

The big financial scandal of the young german history: which responsibility have scholz and merkel?

How do politicians act when it comes to coarse money, hypes with international dimensions, fraud, networks, personnel lenses, vanities and savings of numerous investors? The wirecard scandal brings a lot to the light and is a hub-hated concrete counterpuck to all the infotainment debates on politicians, which present themselves as chancellor’s candidates, in which it went above all about images and moods.

Fotokunst on the art karlsruhe 2014

The artistic photography has been an integral part of the art market for several years. How self-misused art and photography forming museums. Galleries that have not specialized in photography show increasingly photographic art. This is reflected in the this year’s kind karlsruhe. The art fair starts today thursday, 13. Marz and ends on sunday, 16. March.

A good dozen photographers show the galleries in so-called one artist shows, these are solo exhibitions that stand out from the mass of exhibition flats. Heise photo has visited most of them at a first meters.

Adac: 2010 was a year of breakdowns

Adac: 2010 was a year of breakdowns

Munich, 1. February 2011 – adac was busier in 2010 than ever before. In total, the club’s approximately 1700 roadside assistance personnel and their road service partners were involved in 4.250.724 breakdowns. Compared to the previous year, this was an increase of 8.1 percent.

The highest number of operations on 4. January 2010

One reason for this, according to the automobile club, was the harsh winter at the beginning of last year. January 4. January 2010 was the busiest.798 breakdowns, was the day with the highest number of calls. But it was not only the icy cold that caused weak batteries and other technical defects. In the summer, too, the roadside assistance teams had to cope with extreme heat of over 35 degrees celsius. The changed travel behavior of vacationers – according to the adac, more and more vacationers are traveling by car – is another reason for the high number of breakdowns.

Battery as most frequent cause

Defective or flat batteries were the most frequent technical cause of breakdowns to which roadside assistance was called. Over 900.000 times the vehicle was jump-started. Other breakdowns were caused by ignition systems and tires, followed by starters and alternators. But not always when the adac was called, it was due to a defect in the car. Almost 100.000 motorists needed help because they had locked themselves out. Around 25.000 times they were able to continue their journey "fuel donation" fuel donation. In 186.000 cases, adac helped at the scene of the accident, secured the road or provided first aid.

Softwarequality: amazon releases codeguru for productive use

SoftwareQuality: Amazon releases Codeguru for productive use

As part of its last-year-old customer event re: invent amazon had already introduced the service codeguru. Now developers are the tool for quality control and code optimization released in a version (ga – general availability) available for productive use. Codeguru uses the analysis of machine-learning algorithms to create proposals for more efficient codes design and contribute to a higher quality.

The tool adapted to use with a variety of aws services combines two components, a reviewer and a profiler. Codeguru reviewer can integrate developers like other prousing tools in their development process when they import new java code into their repository. Codeguru not only support aws codecommit, but also github, github enterprise or bitbucket cloud. Codeguru reviewer then open a pull request and starts checking automatically. The integrated ml models have been amazon with code review data of more than 10.000 open source projects trained on github.

Check and examine

The second component, the codeguru profiler, should help developers to find their "most expensive lines code", as it is called in the amazon blog post to envision of the tool. For this purpose, the profiler developers gives insights into the runtime behavior of their software to provide any performance bottlenecks and to initiate measures to resolve as well as the general optimization of the code. The aim is to improve the java code (or more jvm languages) so far that the compute costs for use of the software on cloud services such as aws lambda, amazon ec2, amazon ecs, aws fargate or aws elastic beanstalk, but also on-premises, have to be kept low.

About the opposed, but often successful argumentation strategies of germany’s large carbon dioxide ier rwe

Nuclear power? Helps against climate change. Climate change? Is not a concrete danger. The argumentation strategies of germany’s large carbon dioxide ier rwe are quite opposed, amazingly multi-faceted and often crowned success. Without them, the bundestag was probably not allowed to build the coarse carbon dioxide spin in europe

Contrusion freedom looks a little different: on the one hand, the essener energieriesieg rwe emphasizes its nuclear contribution to the reduction of the greenhouse effect: "our nuclear power plants", four at the number, "avoid around 40 million tons of carbon dioxide emissions in the year."The exit from nuclear energy, rwe is talking about, from the point of view of climate care. On the other hand, the company dear in september 2006 to deny his salaries before the kolner oberlandesgericht that the greenhouse effect is a real problem at all. The lawyers, staffed by the renowned law firm baker mckenzie, languages of "subjective perception" of a "adopted [n] danger", which is "neither concretely opposite".

Patch now! Attacks on E-mail Security Appliances of SonicWall

Admins that use sonicwall email security should bring the protective software to the current status. The reason for the network uplift documents are on systems. In error-adjusted versions, the developers have closed three security.

Admin accounts from nothing

At the most dangerous, the as "critical" stained vulnerability with the id cve-2021-20021. Successfully set the attacker at the lucke, they were able to create a warning message by sending the blobe sending praparized http traffic without authentication admin accounts.

By taking advantage of another lucke (cve-2021-20022), attackers were able to load files on systems. The degree of threat is considered "high". The third vulnerability (cve-2021-20023) has not yet been classified. An attackers could access actually silenced files. What cheeks take advantage of attackers is currently unknown.

Finally friendly

Koln, 22. February 2013 – citroen shows at the geneva motor show (7. To 17. Marz 2013) a slightly refreshed c3. The success model has been sold almost three million times since 2002.

Finally friendly

The changed form of coarse air intake lit the small car a lot more friendly than the process ongoing since 2009 with its comparatively aggressive grill. Significantly of seruser and adult makes him the brand logo, which has now adapted to the other models and spreads wide between the headlamps with chrome strips. Led strips in the stobfang now serve as daytime running lights. The tail lights are supplemented in the lower area around lateral jerk emitters. In addition to a new blue as a baking paint "bleu encre" (ink blue) are also offered for the c3 seat cushion, whose colors are matched to the trim of the valve board.

New three-cylinder

As new engines citroen offers the "pure tech"-ottomotors. The two 68 and 82 hp three-cylinders have a displacement of 1.0 and 1.2 liters and should consume around a quarter less fuel than the four-cylinder in the process. The manufacturer estimates the manufacturer to 4.3 or 4.5 liters. As a further gasoline engine, the known vti 120 can be ordered.
