Mobile Phone Use Soon To Be Allowed On European Flights

savuporo Re:I'd pay for a non-phone flight (93 comments)

The actual problem with using cellphones in airplanes used to be the cell towers themselves in and around takeoff and landing corridors. Basestations would often go bonkers over too many nodes entering and exiting it at high speeds. Presumably latest 4G generation of the tower upgrades have reduced these kinds of issues enough that it does not pose a serious problem to carrier networks anymore. Statistically, there is an active cellphone probably on every single flight taking off and landing today, so the techs looking after the macrocells would have a pretty good idea if enabling it all full scale is safe or not - safe for carriers, of course.

Small Restaurant Out-Maneuvers Yelp In Reviews War

savuporo Re:The review ecosystem is good and truly broken.. (249 comments)

There is a way to fix the review systems.

Topical trust networks. I want to CHOOSE whose reviews i actually trust on any given subject. I trust Bobs opinions mostly on movies, but he knows nothing about gardening tools. I want an easy option of removing Bob and his likes out of the rating for gardening tools that gets displayed for me.

Same deal with Bobs taste and expertise in indian food.

When i start researching a completely new topic, say like 50ies italian vintage cars, i prefer to start with an auto-created small trust network comprised of community voted experts. Also, what my facebook "friends" think of any subject has absolutely no value to any of the reviews, so its not a "social" subject.

Also, reviews and opinions on some subjects should decay in weight pretty rapidly. Pastel painting reviewed 20 years ago is totally up to date. Small thai food joint at the corner reviewed 20 years ago is not.

All this is implementable, and i'm surprised that most review sites still keep using a stupid one dimensional "average" of scores.

The Quiet Revolution of Formula E Electric Car Racing

savuporo Re:quiet = powerful (116 comments)

Eliica did 230mph, in 2004.
TTXGP bikes are closing in on gas bike speeds rapidly. In Pikes Peak hill climb electrics actually BEST some ICE cars in a few categories - because air breathing engines start to run out of air at altitude.
There is no fundamental reason of physics or engineering that would dictate electric drivetrains top speed to be any slower than ICE.

In other words, you are wrong.

Tox, a Skype Replacement Built On 'Privacy First'

savuporo Trust agility (174 comments)

Easy way to make this much more useable is to keep the current user rendezvous infrastructure, but use a layer on top for key exchange that goes through user-elected central servers.
The entire Moxie Marlinspike's trust agility thesis. Let the users choose the central entity that they trust for making the rendezvous via a plugin or a high level protocol layer - something as simple as a REST api over https. Every trust provider just has to provide an API endpoint for signing and exchanging keys.

App to user : Here is Bob's key - signed by Slashdot's server. User: screw you, slashdot got hacked twice and their web looks funnay. I trust no one that comes that way. Does Bob exist on BookFace instead ? And so on. You could also have a distributed database of trust provider endpoints along with their current , recent and overall trustworthiness rankings.

Tesla Model S Hacking Prize Claimed

savuporo Re:So (59 comments)

PIN probably shouldnt be stored in the car, store a salted hash.

By the way, my old 91 Camaro used to have a start "security feature", where they had a basic resistor embedded in the ignition key. If the resistance was off or didnt start and blocked further tries after 3 attempts or something for 15 minutes.

Awesome when the contacts got slightly oxidized : )

"Some of these packages are poor crap" out of tens of thousands in repository ? Oh, the humanity ! How is that different from any other programming language ? 90% of contents of any open source repositories is poor crap, be it github, sourceforge ( is that still alive ?? ) or even volumes of example code docs put out by good wise companies like Google, Apple or Microsoft. Its your job as a developer to sort through the crap that stinks less.
And no, i dont regularly attend parades and do not ride on bandwagons, thanks.

Tesla Releases Electric Car Patents To the Public

savuporo Re:what about the battery patents or chargers? (211 comments)

Most likely is that they want a few of their ideas to become standard - like Supercharger infrastructure. If they manage to get even one major OEM to cooperate and add supercharger receptables, that is a massive win for Tesla.

Microsoft Fixing Windows 8 Flaws, But Leaving Them In Windows 7

savuporo Re:Dear Microsoft.... (218 comments)

Dear Microsoft,

Please make Windows 9 touch only, do not give anyone any menu, use the well known principle of most surprise for the user interface design, break all possible APIs, come up with another Uncommon Language Runtime, force me log into everything with the same username and password security be damned, put Bing on the way of actually getting to internet and if you could Ribbon me another two three screenfuls, all would be dandy.

Only by implementing these urgent measures will you guarantee your local fanbase of 2 people will stay very loyal. And the rest can move on to better things and world will be a better place.

Thanks,
Your local detractor.

How about firing people that installed policies for engineers to NOT speak out about faults and banned them from even talking about it ? Who compiled the not to be used word list of "hindenburg", "death trap" etc ?

Maybe search for causes in your legal and PR and HR departments first. Oh, and execs.

NRC Human Spaceflight Report Says NASA Strategy Can't Get Humans To Mars

savuporo Re:Sorry... (206 comments)

So lets see. This is an NRC report that ONLY considered using SLS as the launch vehicle, and concluded that you cannot get to Mars with that, something has to be done differently.

How about _trying_ something different then for a change, stop trying to build redundant launch vehicles, we already have plenty, and actually invest in enabling technologies that DO get us to Mars.
Like, putting spacecraft together from modules like was done with ISS and other stations before that - except without involving costly human ops. How about refuelling the spacecraft on orbit. How about doing research on partial-g environments, and launching a centrifuge. How about sending some rats en route to Mars to study different radiation shielding approach effectiveness. The list is endless. Actually, NRC PRODUCED all the enabling technology roadmaps, they are available here :
http://www.nasa.gov/offices/oc...
How about actually fricking following these roadmaps ( SLS is NOT in there ) and getting some stuff done ? Advanced radioisotope stirling generator that was outlined as the CRUCIAL enabling technology piece for future exploration ? Cancelled ! Funds are required to build a monster rocket to nowhere instead ...

But, if you keep doing the same thing over and over, no reason to expect a different result. Kill the waste, and start investing in future.

Heartbleed Bug Exploited Over Extensible Authentication Protocol

savuporo Re:Should have upgraded Openssl (44 comments)

Phones are the least of the worries IMO. There are so many internet connected consumer electronics devices around that are based on some lightweight linux stack - SmartTVs, home routers, set-top boxes, NAS boxes, IP security cameras etc come to mind. These things will NEVER get patched because the development teams that put together the original firmware for the last years model are often even not around anymore. "Install Cyanogenmod" is not an option either.
With the "Internet of Things" wave raising, this will only get worse.

I'm not sure there is a reasonable solution there, zero day exploits will continue to be around, and companies will continue to build "embedded" devices that are not really designed to take frequent software updates.

Maybe there is a room on market for consumer oriented security certification brand, which basically tells the buyer - yes, we have reviewed and tested the software stack on this device, and its reasonably safe and sound and the company behind it is reasonably committed to keeping it secure ?

Tesla Model S hacking prize claimed

savuporo savuporo writes  |  about 2 months ago

savuporo (658486) writes "AutoBlogGreen reports: The $10,000 prize for successfully hacking a Tesla Model S has been claimed. A team from Zhejiang University in China claimed victory at the Symposium on Security for Asia Network (SyScan360) event in Beijing by exploiting a "flow design flaw," whatever that means, to gain access to vital systems including the door locks, horn and window controls, while the vehicle was moving.

Last year, potential security pitfalls of high-tech electric and hybrid cars came to light when the DARPA successfully hacked into hybrids from Ford and Toyota. For illustration about why this might become a big deal, here is a video report about Prius ECUs and internal CAN network being messed around with while driven."

Publishers to remove 100s of computer-generated gibberish conference proceedings

savuporo savuporo writes  |  about 4 months ago

savuporo (658486) writes "The publishers Springer and IEEE are removing more than 120 papers from their subscription services after a French researcher discovered that the works were computer-generated nonsense. Over the past two years, computer scientist Cyril Labbé of Joseph Fourier University in Grenoble, France, has catalogued computer-generated papers that made it into more than 30 published conference proceedings between 2008 and 2013. Among the works were, for example, a paper published as a proceeding from the 2013 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, held in Chengdu, China. The authors of the paper, entitled ‘TIC: a methodology for the construction of e-commerce’, write in the abstract that they “concentrate our efforts on disproving that spreadsheets can be made knowledge-based, empathic, and compact”.

savuporo (658486) writes "The two days of DARPA humanoid robotics challenge are now over. 16 teams entered in three categories — custom built humanoid, DARPA supplied Atlas platform and a non-humanoid form and competed in 8 different tasks. All Japanese SCHAFT team scored 27 out of 32 maximum points, folowed by IHMC Robotics and Tartan rescue following with 20 and 18 points. The tasks included challenges like driving a vehicle, climing ladders and walls, using handheld tools to cut through walls etc. All robots had a mix of autonomy with teleoperated controls to accomplish the tasks. Full details on scores can be found here
The 8 teams that scored highest will get continued funding from DARPA to compete in the final challenge in 2014. Two NASA teams also entered, and JPL build non-humanoid RoboSimian placed 5th, whereas JSC built and touted "Valkyire" came out of competition with zero points.
Team Shaft and Boston Dynamics building the Atlas platform were recently acquired by Google."

Chang'e-3 lunar lander launching tomorrow, 37 years after last lunar landing

savuporo savuporo writes  |  about 10 months ago

savuporo (658486) writes "China will launch the Chang'e-3 lunar probe at 1:30 a.m. Monday ( China time, or December 1 Sunday at 17:30 UTC ) from Xichang Satellite Launch Center on a CZ-3B carrier rocket. It is planned to enter lunar orbit on Dec 6th and surface landing on Dec 14th if all goes according to the plan. Webcast may become available on the CCTV mission site.
The last time a spacecraft soft landed on the lunar surface was a Soviet Luna-24 sample return mission in 1976. The other currently developed lunar landers are from Google Lunar X-Prize contestants, with none planning to launch before 2015 at the earliest, given funding.
CNSA is collaborating with ESA for spacecraft tracking operations, and has been collaborating with Russian partners in for building its radioisotope heater unit ( RHU ). NASA is blocked from collaborating with CNSA on this mission.
Change'-3 predecessor orbiter mission Chang'e-2 has been very successful and was flown on an extended mission leaving lunar orbit into deep space.
A BBC article talks about future lunar exploration plans, with Chang'e-4 that is built as a backup craft for Chang'e-3 and will be likely launched in 2015, followed by Change-6 and 7 that are designed as sample return missions."

FTA: NHTSA wants automakers to make it impossible to enter text for messaging and internet browsing while the car is in motion, disable any kind of video functionality and prevent text-based information such as social media content or text messages from being displayed.. Obviously these regulations would need to go beyond cellphones, as laptop, tablet or any other gadget with a 3G data connection or even on a wifi hotspot made by your phone would be equally distracting."

An Open Letter to Google Chairman Eric Schmidt on Drones

savuporo savuporo writes  |  about a year and a half ago

savuporo (658486) writes "DC Area Drone User Group has posted an open letter in response to recent comments by Eric Schmidt about banning drones from private use. Closing section:
Personally owned flying robots today have the power to change the balance of power between individuals and large bureaucracies in much the same way the Internet did in the past. And just as the military researchers who developed GPS for guiding munitions could never have imagined their technology would be used in the future to help people conduct health surveys in the world’s poorest countries or help people find dates in the world’s richest, there is a whole world of socially positive and banal applications for drones that are yet to be discovered. We should embrace this chance that technology provides instead of strangling these opportunities in their infancy. Our hope is that you and the rest of Google’s leadership will embrace this pro-technology agenda in the future rather than seeking to stifle it. We would welcome the opportunity to speak further with you about this topic."

Air Force UAV Controls Infected with Virus

savuporo (658486) writes "DefenseTech story "Air Force’s UAV ground control systems (GCS) at Creech Air Force Base, Nev., have been infected by a computer virus. The virus, that’s apparently recording drone operators’ keystrokes, was detected about two weeks ago. While it hasn’t prevented the service from flying UAV missions, it has proven to be difficult to remove — Air Force technicians are having to completely wipe the GCS’ internal hard drives to get rid of the virus. Service officials still aren’t 100 percent sure how it penetrated Creech’s firewalls nor do they know where it came from. It may be a run of the mill computer virus that somehow made its way into the base’s systems or it may be a sophisticated cyber espionage tool specifically targeting the U.S.’ drone program — no one knows yet."

No word on what OS or chipsets these systems were running, but its pretty safe to bet that it is not vxWorks or QNX or the like .."

Meanwhile, CHAdeMO fast charge standard developed and widely deployed in Japan, used on both Nissan Leaf and Mitsubishi MiEV is gaining momentum with deployments underway both in US and Europe.

Women: stop liking Ferraris to stop Global Warming

His comments were greeted with anger by sports car drivers who insisted that their vehicles' greenhouse gas emissions were tiny compared with those from four-wheel-drive vehicles.
Apparently the news about Tesla Roadster, WrightSpeed X1, The KillaCycle or other electric dragsters doing 8.10 quarter miles havent reached british government yet.
There are lots of other high performance battery-electric vehicles around, which are greener than a Prius when it comes to emissions per mile, even Ferrari itself is promising a hybrid in future. So does this seem to be a case of having our cake and eating it too ?"
