DoT Proposes Mandating Vehicle-To-Vehicle Communications

neonv Hacking (256 comments)

A malicious driver only needs to transmit fictitious messages while driving to cause traffic jams, or even worse cause traffic accidents.

An interesting person may force traffic to part for them like some kind of modern day hacker Moses.

Reversible Type-C USB Connector Ready For Production

neonv 100 Watts (191 comments)

Please keep in mind an important aspect of this new cable, it supports 100 watts power transfer. That means most devices, including laptops, can be charged through this one connector. I see that as the best reason to switch, fast charging and universal connector for all my devices. The article glosses over that important detail. It also enables 10 Gbs data transfer.

The Pentagon's $399 Billion Plane To Nowhere

neonv Re:Capabilities (364 comments)

The aim of the F-35 is a possible war with modern countries, not Afghanistan (since we have superiority in Afghanistan, most any aircraft would do). This includes not only where their technology currently is, but where we know they are going. The Chinese and Russians have some incredible defenses, and there's a constant back and forth of advancing weapons and defenses to counter those weapons. This happens whether you're aware of it or not, and most people have no idea what's out there in terms of weapons and defenses because countries mostly keep them secret. The F-35 is part of that superiority strategy, including all of the technology onboard the aircraft.

I'm am in agreement about the A-10. The F-35 in no way replaces what the A-10 can do, and the A-10 does it at 1/10th the cost. I wish they would bring it back into production rather than mothball a very useful aircraft.

The Pentagon's $399 Billion Plane To Nowhere

neonv Capabilities (364 comments)

This article doesn't mention the incredible upgrades of the F-35. It has incredible situational awareness (SA), highly networked to acquire SA from all sources, sensors onboard to provide SA, smaller that the F-22, more stealthy, and a range of other characteristics that the pentagon desires (wiki). Those capabilities are the top reason for the F-35 to exist at all. As development has progressed, then the money problems and failures came up as they always do. The capability needs don't justify the failures of the program, but they need to be taken into consideration when there's talk of changing or canceling the program.

Everyone has a different concern. Congressmen are probably concerned about money staying in their state to stay elected. The Pentagon is worried about capability and not being embarrassed over a big failure. The tax payers are worried about not wasting money and some of them about keeping an F-35 job. It's a complicated issue with lots of caveats.

Amazon Confirms Hachette Spat Is To "Get a Better Deal"

neonv Re:Fight for consumers (211 comments)

And my suspicion is that Amazon could care less about consumers other than their impact to their bottom line.

Amazon's profit margin is almost non-existent. They've never had much profit. They pass the savings to the consumer and take almost nothing. I don't see any indication that it will change.

Companies are not evil just because they exist.

Survey: 56 Percent of US Developers Expect To Become Millionaires

neonv Very simple (467 comments)

Becoming a millionaire in a person's lifetime is very simple and most people can do it. Contribute 10% of your income to your retirement accounts over the course of your lifetime into a diversified portfolio, and you will become a millionaire. Time and discipline are the keys, not generating a large income. Unfortunately, most people are missing one of those two attributes.

Nokia Had a Production-Ready Web Tablet 13 Years Ago

Is Traffic Congestion Growing Three Times As Fast As Economy?

neonv One data point does not a proof make (187 comments)

According to INRIX, traffic in the U.S. reversed two consecutive years of declines with a six percent increase in 2013. The country's GDP, by comparison, grew 1.9 percent last year. INRIX suggests that continued economic growth will result in more traffic congestion, longer commutes, and more productivity losses.

INRIX is getting their conclusion from one data point: last year. Even though previous years do not support their conclusion, multiple data points. As a result, their conclusion that traffic increases at 3 times GDP growth is not convincing. They need to put a lot more effort into this study. Even the article author pointed that out,

Bottom line: roadways are complex ecosystems, and congestion results from jobs, commuters, road work, mass transit, and countless other factors. While it's encouraging to see traffic jams as symbolic of economic growth, that's not an accurate or complete picture.

In a complex environment like this, data needs a control point and a link from cause to effect. All I see here is a very loose correlation in one year of data. Hence, this is FUD.

Ask Slashdot: Anti-Camera Device For Use In a Small Bus?

neonv Jamming (478 comments)

Jamming makes the required frequencies unusable. Jam the required frequencies using the following methods,

1) Since cameras use visible light, I suggest jamming using a very annoying bright disco ball. Cameras will not be able to adjust, and only very festive people will come on the bus making for a very fun ride.

2) Turn off all the lights and cover the windows. No light means no pictures (except maybe those annoying flashes). You may end up attracting lots of goths and vampire wannabes.

Seriously though, eyes use the same frequencies as cameras, so you'll end up causing problems for everyone's eyeballs. May I suggest setting a rule of no cameras and enforcing it as most everyone else does.

Study Finds Methane Leaks Negate Benefits of Natural Gas-Powered Vehicles

neonv Methane degrades over time (102 comments)

The article does not mention at all that methane breaks down in the atmosphere after about 9.6 years (http://en.wikipedia.org/wiki/Atmospheric_methane#Removal_processes), and creates needed water vapor in the upper atmosphere. Carbon dioxide does not react with anything in the atmosphere on it's own. Hence, methane is preferable in the long term.

US Democrats Introduce Bill To Restore Net Neutrality

neonv Misinformation (535 comments)

Being someone who usually votes conservative, I find that net neutrality among conservatives is largely misunderstood. I continually hear that it requires content to be neutral. Meaning that if one opinion is present on a web page, all opposing opinions must be present as well to maintain neutrality. Everyone here should understand that is false. The source of that misinformation seems to be that the bill could be interpreted to let the FCC dictate content requirements. If the FCC were to do something crazy like that, it wouldn't hold up in court due to free speech, so it's not a reasonable concern.

To prevent misinformation, here are the two views to net neutrality.

1) Pro Net Neutrality: Internet Service Providers (ISP) should not dictate which data sources are allowed, how much bandwidth is allowed from each data source, or charge differently for data sources. For example, Netflix creates up to a third of internet traffic in the evening hours. As a result, ISP's are temped to reduce bandwidth allowed from Netflix to free up resources. Net neutrality would not allow this. This is usually the consumer point of view.

2) Anti Net Neutrality: The ISP's own their equipment, pay for their bandwidth, and can do what they want with it. If they want to shape network traffic to make overall service better, it's their right. This is usually the business point of view.

There are lots of details associated with either option. There can be a hybrid approach taken by the FCC as well. For example, if YouTube traffic gets so bad that I can't load a web page in a reasonable amount of time, then limiting YouTube would be in my best interest. In the rare cases such as that, bandwidth limiting is a good idea. Illegal activity such as child pornography could reasonably be blocked as well.

Here's the wikipedia article.

Obama Praises NSA But Promises To Rein It In

neonv Re:Self-restraint (306 comments)

A big problem with government is the lack of a higher entity to regulate. The best mechanism to date is the voter entity to remove politicians from office if they don't like something in government. However, that is extremely indirect. It's difficult and unwise to remove a politician over a single issue, and difficult for voters to change the issue directly. Representative democracy is the best form of government to date, but it has shortcomings.

One good aspect of doing business in the private sector is that the government can pick up regulation as a separate entity. It works well. But with issues of intelligence, military, and legislation, the private sector can only play a limited role. Hence the government becomes producer and regulator with the voters becoming the indirect regulator. It's a problem of government that has yet to have a good solution.

Nearly 1 In 4 Adults Surf the Web While Driving

neonv Misleading Statistics (365 comments)

the number of motorists who access the internet (e.g. check email, surf websites, etc.) has nearly doubled over the past four years

This statement implies these people access the internet regularly. However, that's not the question they asked.

13 percent of motorists admitted that they'd accessed the internet while driving

This statement says motorists have accessed the internet at all, meaning at least one time ever in your life, not on a regular basis.

This is a very important distinction that the article glosses over. If I accessed the internet on my phone once 5 years ago, then this survey would call me "one who accesses the internet while driving," which is very misleading. I don't access the internet while driving. The survey should ask something like "have you accessed the internet while driving in the last month." Then the data would be reasonable and give a much better representation of what people do.

Porn-Surfing Execs Infecting Corporate Networks With Malware

neonv Not 40% of Execs (151 comments)

This is not 40% if executives infecting phones. In fact, based on the article, we don't know how many execs get malware on their phone. However, out of that total unknown percentage of execs with malware, 40% of them get their malware from porn sites. The summary is using a method of lying with statistics, letting the reader infer something that isn't true by showing a similar true statistic.

This statistic wasn't even the point of the article, but rather that breaches are not being reported by companies.

Republican Proposal Puts 'National Interest' Requirement On US Science Agency

neonv Re:I'm for it, if... (382 comments)

Every weapon is developed for a specific use and target type in mind, and includes which countries have that type of target. The cost of the weapon is heavily vetted before development is started and constantly monitored. My guess is you're being funny, but what you want to happen does happen. Most of it is unclassified and freely available, it's just most people don't look for it.

I know there are lots of people against military research, but the sudden and intense conflicts in the 20th century taught the world that preparation and hoping for the best is better than no preparation and hoping for the best. And by hope I mean politicians working it out without conflict.

The Feathered Threat To US Air Superiority

neonv Re:Maybe replace with (195 comments)

Put some goddamn cameras and project the image in the cockpit.

Pilots look anywhere and everywhere when they fly, especially for close air support when the targets are on the ground. This is an advantage they have over Unmanned Air Vehicles (UAV), fast response to threats and quick updates to situational awareness. Projectors do not come anywhere close to replacing window capability and the USAF views windows as infeasible for that reason.

But then ... Why have the pilot inside the plane? Project the images in a screen at the HQ and have the pilot sit comfortably while he sips his coffee.

You hit the reason that the USAF is moving towards UAVs. They have quick response time and can direct the AV in a more stable manner. However, autopilots and guidance systems do not come close to completing with a pilot in common sense, not yet anyway. Pilots can look and identify surface to air missiles, anit-aircraft munitions, and other threats on the ground and know to immediately avoid that area while a UAV does not have that capability, and can get shot down. Looking video through a camera does not compare to cockpit view of the combat area. Requests for UAV support have exact steps to go through and do not respond to sudden changes in situations unless an operator interprets the situation and sends new commands, while a pilot can respond to changes in the situation instantaneously. UAVs take dangerous tasks away from pilots very well, but they cannot yet accomplish all tasks.

But then... Why have pilots at all? Send drones for intel and missiles for action.

You hit the goal of the USAF. But it will be a while before UAVs can dogfight and consistently use common sense like a pilot does.

But then... Why go flying? Invest in better optics, put a satellite over the location and act upon your enemies by sending... ninja.

The US Military has the best satellite optics there are, and is constantly improving them. However, when you're looking at an object from 400 km away that's refracted through 100 km of atmosphere of varying temperature and density, there are limits to image quality. Nothing beats using those same optics and getting closer, like on a UAV flying over the object.

Scientists find connection between brain freeze and migraines

neonv neonv writes  |  more than 2 years ago

neonv (803374) writes "Studying migraines can be difficult. They occur almost randomly, making monitoring from start to finish in a lab nearly impossible. Scientists have found a relationship between migraines and "brain freeze," so scientists decided to study brain freeze to find out more about migraines."
