ZFS Hits an Important Milestone, Version 0.6.1 Released 99

Posted by samzenpus
from the brand-new dept.
sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'"

Your post advocates a

(x) technical ( ) legislative ( ) market-based ( ) vigilante

approach to fighting spam. Your idea will not work. Here is why it won't work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)

( ) Spammers can easily use it to harvest email addresses
(x) Mailing lists and other legitimate email uses would be affected
( ) No one will be able to find the guy or collect the money
( ) It is defenseless against brute force attacks
( ) It will stop spam for two weeks and then we'll be stuck with it
(x) Users of email will not put up with it
( ) Microsoft will not put up with it
( ) The police will not put up with it
( ) Requires too much cooperation from spammers
(x) Requires immediate total cooperation from everybody at once
(x) Many email users cannot afford to lose business or alienate potential employers
( ) Spammers don't care about invalid addresses in their lists
( ) Anyone could anonymously destroy anyone else's career or business

Specifically, your plan fails to account for

( ) Laws expressly prohibiting it
(x) Lack of centrally controlling authority for email
(x) Open relays in foreign countries
( ) Ease of searching tiny alphanumeric address space of all email addresses
(x) Asshats
( ) Jurisdictional problems
( ) Unpopularity of weird new taxes
( ) Public reluctance to accept weird new forms of money
( ) Huge existing software investment in SMTP
(x) Susceptibility of protocols other than SMTP to attack
( ) Willingness of users to install OS patches received by email
(x) Armies of worm riddled broadband-connected Windows boxes
(x) Eternal arms race involved in all filtering approaches
(x) Extreme profitability of spam
(x) Joe jobs and/or identity theft
( ) Technically illiterate politicians
(x) Extreme stupidity on the part of people who do business with spammers
(x) Dishonesty on the part of spammers themselves
( ) Bandwidth costs that are unaffected by client filtering
( ) Outlook

and the following philosophical objections may also apply:

(x) Ideas similar to yours are easy to come up with, yet none have ever
been shown practical
( ) Any scheme based on opt-out is unacceptable
( ) SMTP headers should not be the subject of legislation
( ) Blacklists suck
(x) Whitelists suck
( ) We should be able to talk about Viagra without being censored
( ) Countermeasures should not involve wire fraud or credit card fraud
( ) Countermeasures should not involve sabotage of public networks
(x) Countermeasures must work if phased in gradually
( ) Sending email should be free
( ) Why should we have to trust you and your servers?
( ) Incompatiblity with open source or open source licenses
( ) Feel-good measures do nothing to solve the problem
( ) Temporary/one-time email addresses are cumbersome
( ) I don't want the government reading my email
( ) Killing them that way is not slow and painful enough

Furthermore, this is what I think about you:

(x) Sorry dude, but I don't think it would work.
( ) This is a stupid idea, and you're a stupid person for suggesting it.
( ) Nice try, assh0le! I'm going to find out where you live and burn your
house down!

Bug

+ - The Joys of Running a Bug Bounty Program->

Submitted by Trailrunner7
Trailrunner7 (1100399) writes "When Barracuda Networks started its bug bounty program about three months ago, company officials weren't exactly sure what to expect. They didn't know whether there'd be an onslaught of submissions or the sound of crickets chirping. The reality turned out to be somewhere in the middle.
Overall, the company has been getting about 10 bug reports a month, none of which has been very serious. But that doesn't mean the program hasn't been a success. Peck said that Barracuda also had run into the same problem that Google and others have: hackers don't pay much attention to directions. The company set out specific parameters for what kind of vulnerabilities in which products were in scope for the rewards, but some researchers still submitted flaws that were out of bounds, including bugs in partners' products or in the Barracuda corporate Web site."

Archangel Michael (180766) writes "Smart phones have, for the first time, out sold computers.

For me, this is a milestone really worth mentioning, as it clearly indicates that smart communication devices are replacing computers. I know my phone can do some 65-80% of what I used to do on my computer.

In related news, Apple is slated to become the most valuable company in the world, partially based on its iPhone sales.

Submitted by Orome1
Orome1 (1901578) writes "It's basic economics — as the number of sold smartphones continues to rise worldwide, so will the number of threats targeting the users of these devices. One of the biggest threats is (predictably) expected to be malware disguised as or bungled with legitimate applications. The fact that regulated and an even greater number of unregulated app markets are currently springing up left and right, we'll probably not have to wait long for the fulfillment of that particular prediction."

mantis2009 (1557343) writes "The BBC describes a project underway at the Swiss Federal Institute of Technology that envisions an online, Wiki-like database to "let robots share and store what they discover about the world." Ideally, the project, named "RoboEarth," would give robots the ability to learn from one another in robust ways, significantly decreasing the time it takes for robots to learn how to perform tasks. The article quotes from researcher Dr. Markus Waibel, who says that a main goal of RoboEarth is to promote standardization for roboticists. "The key is allowing robots to share knowledge," said Dr. Waibel. "That's really new.""

Submitted by Zothecula
Zothecula (1870348) writes "For those of us who live in the developed world, internet access has become pretty much a given. It’s become so ubiquitous that we almost expect to have it at all times and in all places, but even in this “Information Age,” the majority of the world’s population lacks access to the internet – either because service isn’t available where they are, or they can’t afford it. Kosta Grammatis has a plan, however. Through his charity group ahumanright.org, Grammatis aims to set up a network of satellites that will provide free internet access to everyone in the world. He’s starting by attempting to buy a single used satellite that’s already in orbit and moving it to a location above a developing country."

Submitted by Anonymous Coward
An anonymous reader writes "We've seen high-fallutin proposals to tackling the space junk problem before — and now the Japanese space agency JAXA has teamed up with Japanese fishing net maker Nitto Seimo to haul in some of the 100,000-plus objects of space junk orbiting the planet. AJAXA satellite will deploy and release a kilometers-wide net made by Nitto Seimo of ultra-thin triple layered metal threads. The net will gradually be drawn into Earth’s magnetic field and burned up along with the abandoned satellites, engine parts and other litter it’s collected."

+ - Did vikings use the same compass as birds and bees->

Submitted by Anonymous Coward
An anonymous reader writes "If you've been wondering how Vikings found their way from Scandinavia to America, polarizing light birds and bees use as a season-and-latitude-independent compass calibration reference may be the answer.

In the case of the Vikings, they possibly used one of two crystals, cordierite, also called lolite, of Norway, or calcite of Iceland.

By holding a polarizing crystal up to the sky and rotating it, you can determine the direction of the Sun. Summer, when sailors far north ventured upon the seas, they were confronted with nearly perpetual daylight, preventing them from using the stars to navigate. Light consists of electromagnetic waves that oscillate perpendicular to the direction of the light's travel. When the oscillations all point in the same direction, the light is polarized."

Submitted by Anonymous Coward
An anonymous reader writes "A judgment issued today by Judge Birss in the Patents County Court has derailed the threatening letter-writing activities by legal firms such as ACS:Law in pursuit of illegal file-sharers.

In his judgment, Judge Birss questioned whether IP addresses could be used as sound evidence in identifying someone and accuse them of illegal file-sharing. He reasoned that IP addresses were not enough, citing unsecured home wireless networks and the fact that an IP address doesn’t identify the individual that is alleged to have illegally file-shared."
