So from what I gather, your coworkers have degrees, most likely took humanities classes to get those degrees, and it did not seem to do a whole lot of good. So who is benefiting from them paying for those humanities classes?
A single engineer approved a part change from a subcontractor. This probably happens daily on these vehicles. The delphi engineers probably thought that they were just improving the reliability of their ignition component and probably do not have insight into any safety critical functions that it plays when integrated with the larger vehicle. The GM engineer was in the best position to see how ignition reliability would effect safety, but even then I would not describe it as obvious. The faulty ignition switch may have been determined to be the root cause of the problem, but there were a number of other causal factors in these deaths. From what I have read, it appears that GM was made aware that they had a reliability issue, but nobody put it together that this could ultimately result in a failure of the safety systems. There have been many cases where known safety issues are intentionally swept under the rug, but this one appears to be an honest engineering mistake.
It was Delphi that changed the part and kept the same part number. GM was notified and approved the change. This happens all of the time with sub contractors and it is not usually done as some sort of scandalous cover up. It is usually done to reduce the costs of the part change by avoiding having to change instruction manuals, catalogs, drawings, diagrams, inventory systems, etc...
There are standards in place (or at least in mature draft form), but I agree with your general sentiment.Those predicting that we will see an overnight transformation (I think Cisco predicted $14 Trillion in value creation of the next 10 years?) are probably not being realistic. Bridging Bluetooth-LE to the internet - see IETF draft spec for 6LoWPAN for BTLE (6LoWPAN = IPv6 for low power personal area networks). Wifi works in some use cases. If the device only connect once every 10 mins, then it does not consume a lot of power to cycle on the wifi, perform transfers, and then cycle off. When it comes to low power wireless, duty cycling is pretty much the key. Technologies like BTLE just have built in duty cycling and with Wifi or 802.15.4 you have to manage it via the software. Networking companies like Cisco are already moving in the direction of directly integrating 6LoWPAN 802.15.4 radios into industrial Wifi access points, so that is how I see this playing out on the consumer side as well. Its not like your 802.11 router has only a single radio anyhow, so if a router also shipped with an 802.15.4 radio + 6LoWPAN bridge, then having low power IP is feasible.
Authentication and Security are the two really big issues that will have to be tackled.
I agree that NSA employees should not be killed. But those that have abused this system should face justice if they have violated the law. We have at this point, irrefutable proof the James Clapper committed perjury. We know that other crimes have been committed within the NSA, an investigation needs to identify the parties responsible and they need to be brought to justice. It is also clear that there is rampant fraud, waste, and abuse in the forms of programs that have no value to US citizens and only serve to increase the power of the intelligence community. Those programs need to be shut down along with appropriate reductions in force.
The same could be said for attacking other nations. You may not care about the citizens of other countries, but our actions toward them have ramifications. Sometime in the form of blowback, sometimes in the form of direct cost to the tax payers. Right now, most of the NSA work appears to be motivated by politics or the hopes of the intelligence community to justify their own existence by getting lucky enough to stop a terror attack. The intelligence gathering arm is failing to produce anything of value and the cyber attack arm has cost the US a great deal of value by hurting many companies and giving every other country in the world the justfication needed to conduct cyber attacks against us. Our infrastructure is more vulnerable than ever to cyber attack, and the government agency that should be making sure our networks are secure is putting us all at greater risk, and for no apparent benefit.
It may be the NSA's job to spy on foreign goverments, but there has to be form of rationale behind it. It is good to have the capability when there is a need, but right now, it seems that the NSA's actions are not tied in any way to the needs of this countries citizens. Most of the spying appears to be politically motivated and done for the benefit of persons/politicians/companies that are part of the intelligence community. As far as economics go, who determines where the economic interests of the citizens lie? Should the NSA spy on BP for Exxon? Which companies employs more US citizens? does it matter that Exxon is headquartered in the US? In an era of huge multi-national companies, how can anybody make an unbiased decision on which "freind" should be subject to spying and which "freind" should receive a direct benefit?
The only way the the spying machine can function and provide value for the tax payers is if it is restrained with the correct set of checks and balances, transparency, and oversight.
I still think it is a stretch to characterize DDOS as computer hacking or whatever other legal term they are using that puts it on par with spreading malicious software and other things that involve defeating security measures and stealing data. Technically, these DDOS relies on the workings of the internet and if a company relies on the workings of the internet for its business, then angry DDOSers, are part of the cost of doing business on the internet. The government should not be involved in deciding what type of traffic is allowed or unallowed over these telecommunications networks.
I think that they will need to repeal a lot more than just the Patriot Act at this point. Besides, it is not like operating outside the law has detered these organizations in the past. The only solution is to accept that no government office should be above scrutiny.
4X the cost? That seems rather high. I have purchased my last Arduino in the $20 range and if you are really cheap you can get the knockoffs on ebay for a lot less. The RasPi and Arduino were never meant to do the same things. Case in point, I have witnessed student teams tackle the same problem with real time sensing using the Pi and the Arduino. The Pi team ran a full linux distro and built their applications using python. The Arduino team used the Arduino. The systems ran on battery power. As you can imagine, the Arduino design was much more efficient and was actually developed just as quickly. On the other hand, I would not use an Arduino as a network router, fileserver, or media player.
In my opinion, the next cool thing for the electronics hobbyist is not in the ever increasing push for more FLASH/RAM and smaller size, but in improved, easy to implement, and secure connectivity. Something like pinocc.io
Police are not above the law. Their actions are not completely hiddent from the public eye. You have too much faith in your fellow man. If you give 90% of people the right mix of motivation, rationalization, personal benefit, and risk mitigation, then they will be more than wiling to look past their morals and do the wrong thing. In this case we can be 100% sure that the NSA capabilities are being used to spy on the interests and enemies of powerful individuals. This generally means that they are used to spy on other powerful individuals, like politicians in other countries, or CEOs of major companies. So you are right that most of us do not have to worry about this simply because we are not a threat to the those powerful individuals.
Similar experience here. It was not like the sequestration snuck up on everybody. Any program that was caught off gaurd by this was being severely mismanaged. In fact, I would say that the sequestration was a very good thing. It forced our organization to look at ways of improving operations. Our organization cut most travel and conferences. At the end of the year, not only had our division covered the budget cuts, but they actually ended up with an enormous surplus.
Not expending 100% of funds and taking on as much risk as possible is not even close to the same thing as having a "slush fund". And government auditors do not care if you fail to expend 100% of funds and money goes back to the taxpayer.
Music exists. It is sound, which is a pressure wave that causes an ear drum to vibrate. Treating this effect on the human body as a possessible, physical object requires imagination.
Which is why a neutered legislature in gridlock is probably the best thing that this country can hope for. Personally, I am ready to vote for the candidate that runs on the platform "I promise not to do or touch anything".
Even if they are not in the majority, they still have a responsibility to negotiate on behalf of the people that elected them. They cannot just bow out of every vote because they are in the minority. The grid-lock that is happening right now is exactly the way this system is supposed to work. It is by far preferrable to what normally goes on. There is a significant percentage of the voting populace that would not mind the debt ceiling being frozen and obama-care being stopped. So if you want to get more votes from the right, you might have to concede something like spending cuts or a delay in portions of obamacare. I personally think that a government shutdown is a great thing for this country to help it get its head around what government services are actually necessary and essential. I don't want to continue paying my governement to spy on me and my family.
Every US Government agency reports personnel shortfalls across all fields in every branch of the organization. This despite the fact that we are experiencing ever higher levels of government spending, particularly in the DoD. I gaurantee that they are already experiencing shortfalls in secretaries. Is it because there are not enough qualified individuals to perform secretary jobs or because people with the right experience hate the idea of working for the Federal Government where they would get excellent benefits and very small chance of ever being fired?
I don't think this "requires" the cloud. It is offered as a service, but can be run locally. I do think that the cloud will eventually be necessary to really make home automation appealing to the masses. People will need a system where they by their blender, scan the nfc tag or qr code, and immediately get that registered in the cloud system. I do not think that the brains for the day to day automation needs to be in the cloud, but the clould definitely has a role in helping automate parts of peoples lives.
I do not really see WigWam as being a product built to compete with current off the shelf products. As evidenced by their release of the Arduino and RasPi Dev kits, It is really geared for tinkerers interested in the engineering of automation systems not just the building of a single automated home. They are providing a system with two completely open operating systems, hackable hardware, and the scalability and versatility of IP. This allows you to develop completely unique automated systems that would be impossible with existing systems. Not only can you the types of sensors and actuators in the system, but you can actually hack down to the level of changing things like radio duty cycling, routing protocols, and device sleep cycles. You cannot do this with devices like the Digi Xbee products and certainly not with systems like Z-wave or insteon.
I would like to point out that the assertion that the NSA collects metadata is a strawman. A fictitious scenario that was constructed by relabeling plain data as "metadata", because it is perceived to be not as awful as pilfering through personally identifiable information. In fact, phone numbers, Identifying numbers, account numbers, names, times, and dates are all just data. An example of metadata would be something describing the format of a displayed phone number, but the number itself is just pure data. I only bring it up it up because I see even people here on slashdot, who are normally smarter on these issues than the mainstream, are starting to take these falsehoods at face value.
The description of the LIFX is a little off. Only a master bulb uses wifi to create the bridge to the home network. The other bulbs are connected via 802.15.4 physical layer and a 6LoWPAN adaptation layer. This is likely more power efficient than a whole network of wifi bulbs and definitely scales better for a large number of devices.
I think the description of the product is misleading. The system only uses wifi on a single master bulb which bridges the network of bulbs to the home network and allows things like smartphones to control the bulbs. Z-wave and insteon use similar bridging devices for connecting devices to IP networks. The network of bulbs are connected via 802.15.4 at the physical layer, an open standard. On top of this, Contiki implements 6LoWPAN, an IPv6 adaptation layer for low power devices. This is currently a draft IETF standard. If you are looking to install a system, these systems cannot currently compete with the likes of Z-wave, however, if you are into hobbyist embedded development, it is quite nice because you have a variety of hardware available from which to build custom systems and multiple open source frameworks to develop with (Contiki and TinyOS).
So you acknowledge that we all have biases in terms of the careers we pursue. Consider how similar biases can make a product development team more effective when a diverse group of individuals can look at a problem from different points of view. Etsy is an excellent example. I doubt that the majority of their customers are male engineers. Isn't it obvious that one of the best ways to develop products that their customers want is to find competent developers who are also likely to be users of the product? If I am a competent developer, but I loathe and despise video games and I never play them, would you want me working for your game development company?
