Transistors Will Stop Shrinking in 2021, Moore's Law Roadmap Predicts - Dje, 24/07/2016 - 8:35md
Moore's Law, an empirical observation of the number of components that could be built on an integrated circuit and their corresponding cost, has largely held strong for more than 50 years, but its days are really numbered now. The prediction of the 2015 International Technology Roadmap for Semiconductors, which was only officially made available this month, says that transistor could stop shrinking in just five years. From an article on IEEE: After 2021, the report forecasts, it will no longer be economically desirable for companies to continue to shrink the dimensions of transistors in microprocessors. Instead, chip manufacturers will turn to other means of boosting density, namely turning the transistor from a horizontal to a vertical geometry and building multiple layers of circuitry, one on top of another. These roadmapping shifts may seem like trivial administrative changes. But "this is a major disruption, or earthquake, in the industry," says analyst Dan Hutcheson, of the firm VLSI Research. U.S. semiconductor companies had reason to cooperate and identify common needs in the early 1990s, at the outset of the roadmapping effort that eventually led to the ITRS's creation in 1998. Suppliers had a hard time identifying what the semiconductor companies needed, he says, and it made sense for chip companies to collectively set priorities to make the most of limited R&D funding.It still might not be the end of Moore's remarkable observation, though. The report adds that processors could still continue to fulfill Moore's Law with increased vertical density. The original report published by ITRS is here.

7-Eleven Just Used a Drone To Deliver Slurpees and a Chicken Sandwich - Dje, 24/07/2016 - 7:35md
An anonymous Slashdot reader write: A drone has autonomously delivered Slurpees, a chicken sandwich, doughnuts, hot coffee and candy from a Reno, Nevada 7-Eleven to a nearby home. The delivery was made "in a matter of minutes" to two busy working parents near their store in Reno, Nevada, and the drone hovered in place and gently lowered each package to the ground in the family's backyard. "To find customers willing to have their order handled by a flying robot, the companies surveyed households within a one-mile radius of the store from which they planned to deliver," reports Tech Crunch. 7-Eleven partnered with drone-delivery company Flirtey, which has also used its drones to perform a ship-to-shore delivery of medical supplies . They're calling this flight the first FAA-approved drone delivery to a home and a historic milestone in commercial deliveries, and both companies plan to continue working together in the future to perform more testing on drone deliveries.

EU To Give Free Security Audits To Apache HTTP Server and Keepass - Dje, 24/07/2016 - 6:35md
An anonymous reader writes: The European Commission announced on Wednesday that its IT engineers would provide a free security audit for the Apache HTTP Server and KeePass projects. The two projects were selected following a public survey that included several open-source projects deemed important for both the EU agencies and the wide public. The actual security audit will be carried out by employees of the IT departments at the European Commission and the European Parliament. This is only a test pilot program that's funded until the end of the year, but the EU said it would be looking for funding to continue it past its expiration date in December 2016.

Laser-Armed Martian Robot Now Vaporizing Targets of Its Own Free Will - Dje, 24/07/2016 - 5:35md
Slashdot reader Rei writes: NASA -- having already populated the Red Planet with robots and armed a car-sized nuclear juggernaut with a laser -- have now decided to grant fire control of that laser over to a new AI system operating on the rover itself. Intended to increase the scientific data-gathering throughput on the sometimes glitching rover's journey, the improved AEGIS system eliminates the need for a series of back-and-forth communication sessions to select targets and aim the laser. Rei's original submission included a longer riff on The War of the Worlds, ending with a reminder to any future AI overlords that "I have a medical condition that renders me unfit to toil in any hypothetical subterranean lithium mines..."

Homeland Security Border Agents Can Seize Your Phone - Dje, 24/07/2016 - 4:36md
Slashdot reader v3rgEz writes: A Wall Street Journal reporter has shared her experienced of having her phones forcefully taken at the border -- and how the Department of Homeland Security insists that your right to privacy does not exist when re-entering the United States. Indeed, she's not alone: Documents previously released under FOIA show that the DHS has a long-standing policy of warrantless (and even motiveless) seizures at the border, essentially removing any traveler's right to privacy. "The female officer returned 30 minutes later and said I was free to go," according to the Journal's reporter, adding. "I have no idea why they wanted my phones..."

Valve Threatens Counter Strike Gambling Sites - Dje, 24/07/2016 - 9:35pd
An anonymous Slashdot reader quotes a report from HNGN: Game maker Valve is threatening to shut down sites dedicated to gambling with add-ons to its popular Counter Strike game. On Thursday the company sent cease and desist letters to 23 sites, demanding that gambling operations be stopped, and that the sites had 10 days to comply. The row revolves around the software overlays that change the appearance of the characters people play in Counter Strike: Global Offensive (CSGO) and the weapons and other virtual items. Last week the company reiterated that its user agreements ban external sites from asking users to connect their Steam accounts in order to trade items for real money. The company added that it would use "all available remedies" against sites that did not stop players using virtual goods to gamble. Bloomberg reports that in June a class action lawsuit was filed against Valve "for its role in the multibillion-dollar gambling economy that has fueled the game's popularity" -- by a man who had been gambling on the site since 2014. This was followed in July by a second class action lawsuit by a mother on behalf of her son, reports ESPN. "The case alleges that the Valve knowingly allows and profits from teenagers participating in illegal, unregulated and underage gambling of in-game cosmetic weapon skins through third-party sites."

David Tomaschik: Chrome on Kali for root

Planet UBUNTU - Dje, 24/07/2016 - 9:00pd

For many of the tools on Kali Linux, it’s easiest to run them as root, so the defacto standard has more or less become to run as root when using Kali. Google Chrome, on the other hand, would not like to be run as root (because it makes sandboxing harder when your user is all-powerful) so there have been a number of tricks to get it to run. I’m going to describe my preferred setup here. (Mostly as documentation for myself.)

Download and Install the Chrome .deb file.

I prefer the Google Chrome Beta build, but stable will work just fine too. Download the .deb file and install it:

dpkg -i google-chrome*.deb

If it’s a fresh Kali install, you’ll be missing libappindicator, but you can fix that via:

apt-get install -f Getting a User to Run Chrome

We’ll create a dedicated user to run Chrome, this provides some user isolation and prevents Chrome from complaining.

useradd -m chrome Setting up su

Now we’ll setup su to handle the passing of X credentials between the users. We’ll add pam_xauth to forward it, and configure root to pass credentials to the chrome user.

sed -i 's/@include common-session/session optional\n\0' \ /etc/pam.d/su mkdir -p /root/.xauth echo chrome > /root/.xauth/export Setting up the Chrome Desktop Icon

All that’s left now is to change the Application Menu entry (aka .desktop) to use the following as the command:

su -l -c "/usr/bin/google-chrome-beta" chrome

Can Iris-Scanning ID Systems Tell the Difference Between a Live and Dead Eye? - Dje, 24/07/2016 - 5:35pd
the_newsbeagle writes: Iris scanning is increasingly being used for biometric identification because it's fast, accurate, and relies on a body part that's protected and doesn't change over time. You may have seen such systems at a border crossing recently or at a high-security facility, and the Indian government is currently collecting iris scans from all its 1.2 billion citizens to enroll them in a national ID system. But such scanners can sometimes be spoofed by a high-quality paper printout or an image stuck on a contact lens. Now, new research has shown that post-mortem eyes can be used for biometric identification for hours or days after death, despite the decay that occurs. This means an eye could theoretically be plucked from someone's head and presented to an iris scanner. The same researcher who conducted that post-mortem study is also looking for solutions, and is working on iris scanners that can detect the "liveness" of an eye. His best method so far relies on the unique way each person's pupil responds to a flash of light, although he notes some problems with this approach.

Phones Without Headphone Jacks Are Here... and They're Extremely Annoying - Dje, 24/07/2016 - 3:35pd
A few weeks ago, we had an intense discussion on what would happen if Apple's next iPhone doesn't have a headphone port -- and what that means for the rest of the industry, as well as the pros and cons of ditching the legacy port. Over the past few months, we have seen many smartphone manufacturers launch new handsets that don't have a headphone jack. Mashable has a report today in which it says that it is already causing frustration among users. From the article: In the Android camp, phones like Lenovo's Moto Z and Moto Z Force and China's LeEco have already scrapped the 3.5mm headphone jack; to listen to music on the company's three latest phones, users need to plug in USB Type-C headphones, go wireless, or use a dongle. I'm all for letting go of old technologies to push forward, but what is happening is actually going to make things worse. The headphone jack has worked for 50 years and it can work for another 50 more because it's universal. Headphones I plug into my iPhone work in an Android phone, in a BlackBerry, in my computer, in my PS4 controller, in my tablet, in any speaker with audio-out, and so on. I can walk into any electronics store and pick up a pair of headphones and not have to worry about compatibility with any of my devices. I know it'll work. [...] With a universal headphone jack, I never have to worry whether or not the crappy pack-in iPhone EarPods I have will work with the Android phone I'm reviewing or not. I also never have to worry if I'll be able to plug my headphones into a friend's phone to listen to some new song. Same applies for when I want to use my earbuds and headphones with another person's device. And there lies the real issue. I will need different dongles -- a Lightning-to-headphone-jack and a USB-Type-C-to-headphone-jack to be prepared because I do carry both iPhone and Android phone on me daily. Dongles also get lost.

Do We Need The Moto Z Smartphones' New Add-On Modules? - Dje, 24/07/2016 - 1:35pd
This week saw the release of the Moto Z Droid and Force Droid, new Android smartphones from Motorola and Lenovo with snap-on modules. Slashdot reader MojoKid writes that the Z Force Droid "is sheathed behind Moto ShatterShield technology making it virtually indestructible." Motorola guarantees it not to crack or shatter if dropped... However, what's truly standout are Moto Mods, which are snap-on back-packs of sorts that add new features, like the JBL Speaker, Moto Insta-Projector and Incipio OffGrid Power Pack (2220 mAh) mods... Even the fairly complex projector mod fires up in seconds and works really well. But the Verge has called it "a good phone headed down the wrong path," adding "this company is competing in the global smartphone market, not a high school science fair, and its success will depend on presenting better value than the competition, not cleverer design. Without the benefit of the value-projecting fairy dust of brands like Apple and Beats, Lenovo will have an uphill climb trying to justify its Moto Mods pricing with functionality and looks, and our review has shown that none of the company's extras are essential."

Turn Your Android Phone Into a Laptop For $99 With the Superbook - Dje, 24/07/2016 - 12:35pd
An anonymous Slashdot reader writes: A company called Andromium is attempting to harness the processing power of your Android smartphone and turn it into a full fledged computer. The 'Superbook' consists of a 11.6-inch laptop shell, which you connect to your phone via a USB Micro-B or Type-C cable, and run the Andromium OS application (currently in beta, but available in the Play Store)... The leader of the project and Company co-founder Gordon Zheng, previously worked at Google and pitched the idea to them... They refused so he quit his job and founded Andromium Inc. In December 2014 the company had introduced their first product which was a dock which used the MHL standard to output to external monitor. That campaign failed, however their newest creation, the Superbook smashed their Kickstarter goal in just over 20 minutes. And within their first 38 hours, they'd crowdfunded $500,000. In an intriguing side note, Andromium "says it'll open its SDK so developers can tailor their apps for Andromium, too, though how much support that gets remains to be seen," reports Tech Insider. But more importantly, "Andromium says its prototypes are finished, and that it hopes to ship the Superbook to backers by February 2017."

'High-Risk Vulnerabilities' In Oracle File-Processing SDKs Affect Major Third-Party Products - Sht, 23/07/2016 - 11:35md
itwbennett writes: "Seventeen high-risk vulnerabilities out of the 276 flaws fixed by Oracle Tuesday affect products from third-party software vendors," writes Lucian Constantin on CSOonline. The vulnerabilities, which were found by researchers from Cisco's Talos team, are in the Oracle Outside In Technology (OIT), a collection of SDKs that are used in third-party products, including Microsoft Exchange, Novell Groupwise, IBM WebSphere Portal, Google Search Appliance, Avira AntiVir for Exchange, Raytheon SureView, Guidance Encase and Veritas Enterprise Vault. "It's not clear how many of those products are also affected by the newly patched seventeen flaws, because some of them might not use all of the vulnerable SDKs or might include other limiting factors," writes Constantin. But the Cisco researchers confirmed that Microsoft Exchange servers (version 2013 and earlier) are affected if they have WebReady Document Viewing enabled. In a blog post the researchers describe how an attacker could exploit these vulnerabilities. TL;DR version: "Attackers can exploit the flaws to execute rogue code on systems by sending specifically crafted content to applications using the vulnerable OIT SDKs."

Timo Aaltonen: Intel Graphics Gen4 and Newer Now Defaults to Modesetting Driver on X

Planet UBUNTU - Sht, 23/07/2016 - 10:37md

Earlier this week Debian unstable and Ubuntu Yakkety switched to load the ‘modesetting’ X video driver by default on Intel graphics gen4 and newer. This roughly maps to GPU’s made since 2007 (965GM->). The main reason for this was to get rid of chasing after upstream git, because there hasn’t been a stable release in nearly three years and even the latest devel snapshot is over a year and a half old. It also means sharing the glamor 2D acceleration backend with radeon/amdgpu, which is a nice change knowing that the intel SNA backend was constantly slightly broken for some GPU generation(s).

Xserver 1.18.4 was released this week with a number of backported fixes to glamor and modesetting driver from master, so the time was right to make the switch now while both Stretch and Yakkety are still on the development phase. So I wrote a small patch for the xserver to load intel driver only on gen2 & gen3 which can’t do glamor efficiently. Newer Intel GPU’s will fall back to modesetting. This approach is good since it can be easily overridden by dropping a conffile to /etc/X11 that uses something else.

I’ve seen only one bug filed that was caused by this change so far, and it turned out to be a kernel bug fixed in 4.6 (Yak will ship with 4.8). If you see something strange like corrupt widgets or whatnot after upgrading to current Yakkety, verify it doesn’t happen with intel (‘cp /usr/share/doc/xserver-xoeg-video-intel/xorg.conf /etc/X11’ followed by login manager restart or reboot) and file a bug against xorg-server. We’ll take it from there.

Salesforce CEO Told LinkedIn He Would Have Paid Much More Than Microsoft - Sht, 23/07/2016 - 10:34md
Ina Fried, reporting for Recode: It was already known that LinkedIn chose a potentially lower all-cash acquisition offer from Microsoft rather than take on the uncertainties of a stock-and-cash deal from Salesforce. But now it has been revealed that Salesforce might have been willing to go "much higher" than Microsoft's $26.2 billion, or change other terms of its bid, had it been given the chance. In a filing with regulators on Friday, LinkedIn said a board committee met on July 7 to discuss an email from Salesforce CEO Marc Benioff. "The email indicated that Party A would have bid much higher and made changes to the stock/cash components of its offers, but it was acting without communications from LinkedIn," LinkedIn said in the updated filing with the Securities and Exchange Commission.

Robert Roth: Need for PC - The plan

Planet GNOME - Sht, 23/07/2016 - 9:43md

I have realized quite some time ago that my PC is struggling to keep up with the pace, so I have decided that it is time for an upgrade (after almost 6 years with my Dell Inspiron 560 minitower with C2D Q8300 quad-core).

I have "upgraded" the video card a couple of months ago due to the old one not supporting OpenGL3.2 needed by GtkGLArea. First I went with an ATI Radeon HD6770 I received from my gamer brother, but it was loud and I did not use it as much as it's worth using, with a high cost (108W TDP, bumped the consumption of the idle PC by 30-40W from 70-80W to 110-120W), so I have traded it for another one: a low-consumption (Passively cooled - 25W TDP) Ati Radeon HD4550 working well with Linux and all my Steam games whenever I am gaming (casual gamer). Consumption went back to 90-100W.

After that came the power supply, replacing the Dell-Provided 300W supply with a more efficient one, a 330W Seasonic SS330HB. This resulted in another 20W drop in power consumption, idling below 70W.

The processor being fairly old, and having a 95W TDP, but with the performance way below today's i7 processors with the same TDP, it might be worth upgrading, but that means motherboard + CPU + cooler + memory upgrade, but as I have the rest of the components, I will reuse them, and add a new (old) case to the equation, a PowerMac G5 from around 2004.

So here's the basic plan:
Case - PowerMac G5 modded for mATX compatibility, and repainted - metallic silver the outer case, matt black the inner case - inspired by Mike 7060's G5 Mod
CPU - Intel core i7 6700T - 35W TDP
Cooler - Arctic Alpine 11 Plus - silent, bigger brother of the fanless Arctic Alpine 11 Passive (for up to 35 W TDP, the i7 6700T being right at the edge, I did not want to risk)
MotherBoard - 1151 socket, DDR4, USB3, 4-pin CPU and case fan controller socket, HDMI and DVI video outs being the requirements - I chose the MSI B150M Mortar because of guaranteed Linux compatibility (thanks Phoronix), 2 onboard PWM case fan controllers + PWM controlled CPU fan
Memory - 2x8GB DDR4 Kit - Kingston Hyperx Fury
PSU - Seasonic SS-330HB mounted inside the G5 PSU case, original G5 PSU fans replaced with 2x 60mm Scythe Mini Kaze for silent operation
Case Cooling - Front 2x 92mm - Arctic F9 PWM PST in the original mounts

Video card - Onboard Intel or optional ATI Radeon HD4550 if (probably will not happen) the onboard will not be enough
Optical drive (not sure if it is required) - start with existing DVD-RW drive
Storage - 120 GB Kingston V300 + 1TB HDD - existing

Plans for later
(later/optional) update optical drive to a Blu-Ray drive
(later/optional)  Arctic F9 PWM PST, in the original G5 intake mounts or 120 mm Arctic F12 PWM PST in new intake mounts.

I'll soon be back with details on preparing the case, probably the hardest part of the whole build. The new parts are already ordered (the CPU was pretty hard to find on stock, and will be delivered in a week or so instead of the usual 1-2 days).

Google Tests Ads That Load Faster and Use Less Power - Sht, 23/07/2016 - 9:35md
Slashdot reader Big Hairy Ian quotes a report from the BBC: Google says it has found a way to make ads load faster on web pages viewed on smartphones and tablets. The company said the ads would also be less taxing on the handsets' processors, meaning their batteries should last longer. The technique is based on work it has already done to make news publishers' articles load more quickly. But it is still in development, and one expert said Google still had questions to answer. The California-based company's online advertising revenue totalled $67.4 billion last year... The technique limits the scope of JavaScript, and "provides its own activity measurement tools, which are said to be much more efficient," according to article. A Google software engineer explains that this technique "only animates things that are visible on the screen," and throttles animation to fewer frames per second for weaker devices -- or disables the animations altogether. "This ensures that every device gets the best experience it can deliver and makes sure that ads cannot have a negative impact on important aspects of the user experience such as scrolling."
