An anonymous reader writes:"Dmitry Bogatov, Debian developer and Tor node admin, is still being held in a Moscow jail," tweeted the EFF Saturday. IT Wire reports that the 25-year-old math teacher was arrested earlier this month "on suspicion of organizing riots," and is expected to be held in custody until June 8. "The panel investigating the protests claims Bogatov posted several incitory messages on the sysadmin.ru forum; for example, one claim said he was asking people to bring 'bottles, fabric, gasoline, turpentine, foam plastic' to Red Square, according to a post at Hacker News. The messages were sent in the name of one Airat Bashirov and happened to be transmitted through the Tor node that Bogatov was running. The Hacker News post said Bogatov's lawyer had produced surveillance video footage to show that he was elsewhere at the time when the messages were posted.
"After Dmitry's arrest," reportsthe Free Bogatov site
, "Airat Bashirov continue to post messages. News outlets 'Open Russia' and 'Mediazona' even got a chance to speak with him."
Earlier this month the Debian GNU/Linux project also posteda message of support
, noting Dmitry maintains several packages for command line and system tools, and saying their group "honours his good work and strong dedication to Debian and Free Software... we hope he is back as soon as possible to his endeavours... In the meantime, the Debian Project has taken measures to secure its systems by removing Dmitry's keys in the case that they are compromised."

Mit moderner Verlegetechnik will die Deutsche Telekom beim Festnetzausbau die Tiefbauarbeiten reduzieren. Das gab das Unternehmen in seinem Firmenblog bekannt. Bei dem Horizontal-Spülbohrverfahren wird das Kabel unter einem Hindernis hindurchgeführt, ohne unterirdische Kanäle graben zu müssen.
Straßen und Gehwege würden nicht geöffnet, sondern durch unterirdische Kabelkanäle gewissermaßen untertunnelt. Straßen und Freiflächen müssten so nicht aufgegraben werden. Auch bei Flüssen und Kanälen lasse sich das Verfahren einsetzen. Bauanträge und langwierige Genehmigungsverfahren würden so weitgehend entfallen.
"Beim Spülbohren müssen nur zwei Gruben ausgehoben werden, jede mit etwa drei Quadratmetern Fläche und einer Tiefe von zwei Metern. An der Startgrube setzt dazu eine Spülbohrmaschine das Bohrgestänge an und treibt den Bohrer schräg in den Boden. Wurde die gewünschte Tiefe erreicht, geht es horizontal weiter - in Richtung Zielgrube", erklärte das Unternehmen.
Allein im Bohrkanal
Die gelöste Erde wird mit einer Bohrspülung aus Wasser und Bentonit in Richtung Startgrube zurückgebracht. Das Bentonit stabilisiert zudem die Bohrlochwand. Trifft der Bohrer auf Gestein oder Bauschutt, muss eine Spülbohranlage mit eingebautem Schlagwerk eingesetzt werden.
Erzeugt wird ein Bohrkanal mit einem Durchmesser von etwa 140 bis 170 Millimetern. Bevor der Bohrkopf zur Bohrmaschine zurückgezogen wird, werden daran die Kabel befestigt. Die Verlegearbeiten sind damit abgeschlossen.
"Mit Spülbohranlagen lassen sich Kabelkanäle von 500 bis 700 Metern Länge erstellen. Spezielle Hochleistungsmaschinen schaffen sogar rund zwei Kilometer", erklärte die Telekom.

An anonymous reader writes:"Mobile applications that open ports on Android smartphones are opening those devices to remote hacking, claims a team of researchers from the University of Michigan," reports Bleeping Computer. Researchers say they've identified 410 popular mobile apps that open ports on people's smartphones. They claim that an attacker could connect to these ports, which in turn grant access to various phone features, such as photos, contacts, the camera, and more. This access could be leveraged to steal photos, contacts, or execute commands on the target's phone. Researchers recorded various demos to prove their attacks. Of these 410 apps, there were many that had between 10 and 50 million downloads on the official Google Play Store and even an app that came pre-installed on an OEMs smartphones. "Research on the mobile open port problem started after researchers read a Trend Micro report from 2015 about a vulnerability in the Baidu SDK, which opened a port on user devices, providing an attacker with a way to access the phone of a user who installed an app that used the Baidu SDK," reports Bleeping Computer. "That particular vulnerability affected over 100 million smartphones, but Baidu moved quickly to release an update. The paper detailing the team's work is entitled Open Doors for Bob and Mallory: Open Port Usage in Android Apps and Security Implications, and was presented Wednesday, April 26, at the 2nd IEEE European Symposium on Security and Privacy that took place this week in Paris, France."

Red Hat on Thursday announced JBoss AMQ 7, a messaging platform upgrade that enhances its overall performance and improves client availability for developers.
JBoss AMQ is a lightweight, standards-based open source platform designed to enable real-time communication between applications, services, devices and the Internet of Things. It is based on the upstream Apache ActiveMQ and Apache Qpid community projects.
JBoss AMQ serves as the messaging foundation for Red Hat JBoss Fuse. It provides real-time, distributed messaging capabilities needed to support an agile integration approach for modern application development, according to Red Hat.
The upgrade be available for download by members of the Red Hat developers community this summer, the company said.
Technology plays a central role in enabling greater levels of interconnection and scalability, noted Mike Piech, general manager of Red Hat JBoss Middleware.
"With its new reactive messaging architecture, JBoss AMQ is well-suited to support the applications and infrastructure that can help deliver those experiences," he said.
What It Does
"Messaging," in this case, relates to commands passing between servers and client devices. Broadly speaking, this kind of technology is called "message-oriented middleware," or "MOM," said Charles King, principal analyst at Pund-IT.
"This is purely aimed at easing the lives of enterprise developers whose organizations are Red Hat customers," he told LinuxInsider. "This is especially true for those focused on IoT implementations, since AMQ 7 can open up data in embedded devices used in IoT sensors to inspection, analysis and control."
JBoss AMQ 7 brings technology enhancements to three core components: broker, client and interconnect router.
The JBoss AMQ broker manages connections, queues, topics and subscriptions. It uses innovations from Artemis to provide an asynchronous internal architecture. This increases performance and scalability and enables the system to handle more concurrent connections and achieve greater message throughput.
JBoss AMQ 7 now offers broad interoperability across the IT landscape, which lets it open up data in embedded devices to inspection, analysis and control.
The new interconnect router in JBoss AMQ 7 enables users to create a network of messaging paths spanning data centers, cloud services and geographic zones. This component serves as the backbone for distributed messaging. It provides redundancy, traffic optimization, and more secure and reliable connectivity.
Two key enhancements in JBoss AMQ 7 are a new reactive implementation and interconnect features, said David Codelli, product marketing lead for JBoss AMQ at Red Hat.
The first is an asynchronous (reactive) server component, so it no longer ties up resources for each idle connection. This will make all their interactions with messaging more performant, both in terms of throughput and latency.
"It also means that more developers can use the system since some asynchronous threading models can't use traditional brokers," Codelli told LinuxInsider.
The second key enhancement is the addition of numerous benefits provided by the new interconnect feature, especially the ability to use one local service.
"Developers can connect to one local service to have access to a stream -- sending or receiving -- of data that can travel throughout their organization," Codelli said, "crossing security boundaries, geographic boundaries and public clouds without the developer having to configure anything."
The messaging platform will better meet the needs of engineering teams who share data in a loosely coupled, asynchronous fashion. Similarly, operations teams will be better able to share feeds of critical data with every department in a company, even if it has a global reach.
"Think giant retailers that need to propagate product defect data as quickly and efficiently as possible," suggested Codelli.
Two more intended benefactors of the application upgrade are financial services software developers, or IT managers dealing with transportation and logistics tasks.
The interconnect feature is ideal for things like payment gateways. It is also more helpful to architects who have to contend with large amounts of disparate data, such as delays and outages, flowing over a wide area.
One of the appeals of MOM technologies and Apache ActiveMQ is that its message modules can be distributed across multiple heterogeneous platforms, Pund-IT's King said. It effectively insulates applications developers from having to be experts in enterprise operating systems and network interfaces.
"A cross-platform value proposition is central to what Red Hat is doing," King observed. "Overall, this new update to AMQ 7 is likely to be welcomed by numerous customers, especially those focused on distributed applications and IoT."
