Red Hat Strips Down For Docker 21

Posted by timothy
from the wearing-or-not-wearing-dockers dept.
angry tapir writes Reacting to the surging popularity of the Docker virtualization technology, Red Hat has customized a version of its Linux distribution to run Docker containers. The Red Hat Enterprise Linux 7 Atomic Host strips away all the utilities residing in the stock distribution of Red Hat Enterprise Linux (RHEL) that aren't needed to run Docker containers. Removing unneeded components saves on storage space, and reduces the time needed for updating and booting up. It also provides fewer potential entry points for attackers. (Product page is here.)

Ask Slashdot: Should I Let My Kids Become American Citizens? 353

An anonymous reader writes "Can you help me decide whether to allow my small daughter and son to become American citizens? I am American and my partner is Swedish. We have both lived in Belgium for many years and have no plans to leave. I became a Belgian citizen some years ago and kept my American citizenship. My partner has both her original Swedish and now Belgian citizenship. We are not married. Instead we have a registered partnership, which is common in northern Europe, confers most of the benefits of marriage, and raises no eyebrows. However, the American government does not recognize such partnerships, so in their eyes I am still single. Generally, children of American citizens abroad automatically become American citizens themselves at birth. But our kids fall under an exception. Male American citizens who live abroad and have children out of wedlock with a non-citizen mother do not automatically transmit citizenship to their children unless they sign an "affidavit of support" promising to support their children until the age of 18. If you don't sign before the child reaches 18, the child is not considered an American citizen. This has been upheld by two Supreme Court rulings (Nguyen v. INS and Flores-Villar v. United States). For legal beagles, the relevant statutes are 8 U.S.C. 1401 and 1409. (Read on below for the rest.)

EU Free Data Roaming, Net Neutrality Plans In Jeopardy 31

Posted by timothy
from the can't-we-all-just-not-get-along? dept.
An anonymous reader writes EU free data roaming and net neutrality plans now look like they are in doubt as European regulators have dropped plans to ban roaming charges and have proposed net neutrality rules allowing privileged access in some cases. This comes as a U-turn of plans [compared to] 2014, when EU MEPs voted to scrap mobile roaming fees in Europe by 15th December 2015, with the proposal orginally covered on Slashdot in 2010."

An anonymous reader writes "Dear fellow Slashdotters,

Can you help me decide whether to allow my small daughter and son to become American citizens?

I am American and my partner is Swedish. We have both lived in Belgium for many years and have no plans to leave. I became a Belgian citizen some years ago and kept my American citizenship. My partner has both her original Swedish and now Belgian citizenship. We are not married. Instead we have a registered partnership, which is common in northern Europe, confers most of the benefits of marriage, and raises no eyebrows. However, the American government does not recognize such partnerships so in their eyes I am still single.

Generally, children of American citizens abroad automatically become American citizens themselves at birth. But our kids fall under an exception. Male American citizens who live abroad and have children out of wedlock with a non-citizen mother do not automatically transmit citizenship to their children unless they sign an “affidavit of support” promising to support their children until the age of 18. If you don’t sign before the child reaches 18, the child is not considered an American citizen. This has been upheld by two Supreme Court rulings (Nguyen v. INS and Flores-Villar v. United States). For legal beagles, the relevant statutes are 8 U.S.C. 1401 and 1409.

The kids have Swedish and Belgian citizenship. We could go down to the American consulate and get American citizenship for them any time, but I keep putting off the decision and I am not sure I want to do it at all. Sentimentally I would like the kids to have American citizenship, but there is really only one practical pro to it:

* American citizenship would allow them to live, work, or study in America more easily, if they choose, when they get older.

The cons:

* They would be immediately enmeshed in the U.S. tax bureaucracy, which would require them to file U.S. tax returns for life even if they never set foot in the U.S. This, as I know from experience, is a huge bother, even when you don’t owe anything.
* Sometimes they would owe U.S. tax, though, for example for capital gains, unearned income, and in some countries self-employment income.
* My son would have to register for the draft.
* The decision, once made, is difficult to back out of: renouncing one’s U.S. citizenship costs $2300 and a lot of paperwork.
* They can easily travel to the US for family visits as Belgian/Swedish citizens.
* There are lots of good universities in Europe. And if they really wanted to study in the U.S., it’s not too hard to do as a European.

What do you think I should do? The clock is ticking, and I find it hard to choose between the evil of not being able to be American if they choose, and the evil of unjust, lifelong pursuit by the IRS.

Yours sincerely,
A loyal Slashdotter.

New Data Indicates Arctic-Ocean Sized Body of Water on Ancient Mars 46

Posted by timothy
from the sounds-brisk dept.
mdsolar writes After six years of planetary observations, scientists at NASA say they have found convincing new evidence that ancient Mars had an ocean. It was probably the size of the Arctic Ocean, larger than previously estimated, the researchers reported on Thursday. The body of water spread across the low-lying plain of the planet's northern hemisphere for millions of years, they said. If confirmed, the findings would add significantly to scientists' understanding of the planet's history and lend new weight to the view that ancient Mars had everything needed for life to emerge. Update: 03/05 22:42 GMT by T : Correction: that headline should have read "Arctic" initially, rather than Antarctic.

zentigger writes Canadians rejoice! It looks like the new anti-spam regulations might actually have some teeth! Today, the CRTC issued a $1.1 million fine to Compu-Finder for violating Canada's anti-spam legislation by sending commercial emails without consent, as well as messages in which the unsubscribe mechanisms did not function properly. Furthermore, an analysis of the complaints made to the Spam Reporting Centre of this industry sector shows that Compu-Finder accounts for 26% of all complaints submitted.

Developers Race To Develop VR Headsets That Won't Make Users Nauseous 119

Posted by timothy
from the or-nauseated dept.
HughPickens.com writes Nick Wingfield reports at the NYT that for the last couple of years, the companies building virtual reality headsets have begged the public for patience as they strive to create virtual environments that don't make people physically sick. "We're going to hang ourselves out there and be judged," says John Carmack, chief technology officer of Oculus, describing what he calls a "nightmare scenario" that has worried him and other Oculus executives. "People like the demo, they take it home, and they start throwing up," says Carmack. "The fear is if a really bad V.R. product comes out, it could send the industry back to the '90s." In that era, virtual reality headsets flopped, disappointing investors and consumers. "It left a huge, smoking crater in the landscape," says Carmack, who is considered an important game designer for his work on Doom and Quake. "We've had people afraid to touch V.R. for 20 years." This time around, the backing for virtual reality is of a different magnitude. Facebook paid $2 billion last year to acquire Oculus. Microsoft is developing its own headset, HoloLens, that mixes elements of virtual reality with augmented reality, a different medium that overlays virtual images on a view of the real world. Google has invested more than $500 million in Magic Leap, a company developing an augmented reality headset. "The challenge is there is so much expectation and anticipation that that could fall away quite quickly if you don't get the type of traction you had hoped," says Neil Young. (More, below.)

Lauren Ipsum: A Story About Computer Science and Other Improbable Things 39

Posted by samzenpus
from the read-all-about-it dept.
MassDosage writes As the full title to Lauren Ipsum: A story about Computer Science and Other Improbable Things indicates, this is a book about Computer Science but what's surprising about it is that it manages to be about Computer Science without actually ever directly referring to the subject or even to computers at all. It is in fact a fictional story about a young girl called Lauren who gets lost after wandering into a forest near her house after an argument with her mother. She stumbles into a world populated with all kinds of strange creatures and colorful characters some of whom she befriends in order to figure out how to get back to her home. The "figuring out" part of the plot is where things get interesting as she has many attempts at solving this problem with different characters giving her often contradictory advice and Lauren then has to decide what exactly she's trying to do and which of the various possible solutions is the best. This involves a fair amount of trial and error, learning from certain mistakes and trying different approaches. If this is starting to sound familiar to those who have written software then that's the whole point. Lauren Ipsum is cunningly littered with references to Computer Science and in particular to things like algorithms, logic puzzles and many other of the theoretical underpinnings of the subject. Read below to see what MassDosage has to say about the book.

Valve Developed an Open-Source Intel Vulkan GPU Driver For Linux 38

Posted by timothy
from the good-news-for-a-change dept.
An anonymous reader writes For those wondering when the first graphics driver for the new Khronos Vulkan API will materialize and for what hardware, it looks like the first driver could very well be for Intel graphics and it might not be too far away. It turns out Valve developed an Intel Linux Vulkan driver to help ISVs bootstrap their new Vulkan code, with Valve planning to open-source this driver code. This is yet another reason to love Valve, especially as Intel graphics on Linux don't even support OpenGL 4 yet.

+ - Red Hat Enterprise Linux 7.1 and Atomic Host Hit General Availability->

Submitted by darthcamaro
darthcamaro (735685) writes "Red Hat today released the first milestone update to its flagship Red Hat Enterprise Linux 7.x (RHEL) platform. Among the new features in RHEL is the dogtag certificate system and improved two-factor authentication support. Perhaps more noteworthy is the first release of Red Hat Enterprise Linux 7.1 Atomic Host which is an optimized version of RHEL specifically for the deployment of Docker containers. Red Hat is using Google Kubernets for orchestration and the OStree open source technology as a way to enable 'snappy' transactional updates and rollback capabilities. Atomic Host also introduces the concept of 'super-privileged' containers. The super-privileged containers allow users to deploy system services as containers and then run those service containers with privileged access to the host system."
