Blood For Extra Credit Points Offer Raises Eyebrows In Test-Mad China

bobcat7677 Blood batteries (90 comments)

Slightly tongue in cheek comment, but who knows when it comes to the Chinese! I am guessing they are really looking to use all the blood to offset some of their energy needs by using some sort of technology like this: http://electronics.howstuffwor... Almost the Matrix in real life:)

The Great Lightbulb Conspiracy

bobcat7677 Re:I dunno about LEDs, but CFLs don't last (602 comments)

Ditto, I have also had CFLs pop on me like that. Also have had probably 75% of the ones I have installed fail prior to their advertised lifetime. They don't really dim (there are CFLs that advertise being "dimmable" but they don't really dim much) and the light they produce is poor quality. I will NEVER install another CFL. OTOH, I have been mostly happy with all the LEDs I have installed so far. The cheap ones are cheap...not much light and the light is poor quality. But they all are efficient, don't contain murcury, have not had one fail yet (even the cheap chinese ones), and the latest Cree stuff dims well and puts off really good light.

CDC: Ebola Cases Could Reach 1.4 Million In 4 Months

bobcat7677 Re:CDC "Estimates" (280 comments)

I take them with a whole salt shaker. An estimate is just an estimate and when it comes to human behavior and viral behavior, both of which tend to be very unpredictable, it's nigh impossible to provide any sort of meaningful prediction. Bottom line: The sky is falling, or it's not, nobody is really quite sure. ...Except the PTSD guy that broke into the white house the other day, he was pretty sure of himself.

Environmentalists Propose $50 Billion Buyout of Coal Industry - To Shut It Down

bobcat7677 Re:Replaced by what? (712 comments)

It would cost much more than $50 Billion to replace that generation capacity. Here are a couple options:

Coal currently produces a ballpark average of 200,000 Megawatts of power for the US continuously (based on the published annual generation totals). So we use that number to figure out how much of alternative generation sources you would need.

Lets start with Nucular since that is (relatively) simple with almost continuous output: Most recent power plan under construction in the US is Watts Bar 2 (look it up) that will produce 1180 megawatts at a cost of ~4.5Billion. To replace 200,000 megawatts you would need about 170 of those Watts Bar 2 plants at a total cost of approximately $763Billion in today's dollars! Wowser. Also note that there is a fuel shortage looming that makes spinning up new multi-billion $ reactors a potential waste of time and $. http://www.nytimes.com/2013/10...

Ok, lets move on to renewables. There are lots of options here...wind, solar, concentrated solar, tidal power, ect. The thing with non-hydro renewables is that most of them are cyclical or random like the weather. So you need huge storage capacity to go with them. Projects like the Bath County Pumped Storage Station are a great solution for this, but for 200,000 megawatts of renewables, you would need about 70 of those at a cost of $100Billion+. Thats just for the glorified "battery" and does not count the cost of the generation facilities themselves which would be hundreds of billions if not $1Trillion+.

Just keeping things in perspective:)

Nest Protect: Trojan Horse For 'The Internet of Things'?

bobcat7677 Re:$129 for a freaking SMOKE ALARM?! (177 comments)

I have to agree. It is cool and can do a few things that a normal smoke detector cant (such as act as a sensor extension for your Next thermostat and notify your mobile if there is smoke and you are not home), but the price does seem a bit steep for what it is. If it was $50 I would have already ordered at least one to go with my Nest thermostat. $130 is painful.

Shots Fired At US Capitol

bobcat7677 Re:Isn't it empty? (608 comments)

1. Yes, Preliminary reports are that the suspect is a woman who had a child in the car. 2. "ramming" may have been an embellishment. I heard it described more like she "tried to go through the gate" but security stopped her. 3. There is no confirmation if the "suspect" even had any weapons. From the preliminary reports, it sounds like the shots fired were actually fired by the police to stop the car from getting away. 4. It was just clarified by the capitol police chief that the injured officer was NOT shot but rather struck by a vehicle.

As Hurricane Season Looms, It's Disaster-Preparedness Time

bobcat7677 Re:Location, Location, Location (117 comments)

Sorry, forgot to mention volcanoes. Mount St. Helens could erupt again too. But the servers are located outside the lava and mud flow paths for all of these (there are maps widely available that show these things). Even a major eruption would be unlikely to pose a physical threat to the servers and damage to electrical or internet infrastructure would be temporary and easily routed around at worst. Probably the most likely thing might be ash from an eruption potentially clogging cooling systems...but that is easily mitigated by making sure the air handling systems in your data center have pre-filters installed.

As Hurricane Season Looms, It's Disaster-Preparedness Time

bobcat7677 Location, Location, Location (117 comments)

We have our servers in a data centers in inland Oregon/Washington. There has never been a hurricane or typhoon within a thousand miles, seismic events are rare, the area is used to large amounts of rain so flooding has minimal effect, the weather is temperate so there is rarely extremes in heat or cold and Tsunamis would have to get past the coast range mountains to be an issue. Basically, nothing ever happens there. I would recommend anyone with important data at least have a DR location in a low risk geographical area.

Boeing 787 Dreamliner Grounded In US and EU

bobcat7677 Re:Safe Batteries (301 comments)

Except Boeing would not be paying that fuel cost. It's customers would. And when you figure the per passenger flight hour rate of the extra fuel for that, it's about $0.0005. Yes, thats 5 100ths of a penny added to the ticket price of a passenger making a 1 hour flight. There is cutting corners and then there is cutting corners. The main batteries of a fly-by-wire plane is not the place to be cutting corners like this. It costs them more to carry the trash you make during the flight then it would to add 18 lbs of safer battery. And that is just figuring the gross fuel cost. That fuel cost would be at least partially offset by a lower maintenance cost since LiFePo batteries would not have to be replaced as often. Beyond that, I am sure that this fiasco has already cost Boeing far more than $1millon and has cost the customers who have had to take ground planes and re-shuffle passengers untold millions. It's all fun and games till a $200million airplane catches on fire.

Boeing 787 Dreamliner Grounded In US and EU

bobcat7677 Safe Batteries (301 comments)

It really seems silly to me that they chose to use a lithium ion battery with a cobalt cathode for use as a critical component of an airplane. They are not environmentally friendly, prone to fire, and don't last as long as some other technologies. They could have gone with a Lithium Iron battery and been much safer and require less maintenance. http://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery That would have only added about 18 pounds to the entire aircraft, certainly worth the greatly increased safety factor. Just goes to show that this plane was built to be a cheap as possible with only cursory regard to safety.

Java Vs. C#: Which Performs Better In the 'Real World'?

New York Passes Landmark Gun Law

bobcat7677 Re:We need gas control! (1591 comments)

I really wish people would look up the word "Infringe" before making statements like this:

"Your "Second Amendment Rights" to bear a gun or a Blue-Rhino gas can have not been infringed.".

infringe /infrinj/ Verb 1. Actively break the terms of (a law, agreement, etc.): "infringe a copyright". 2. Act so as to limit or undermine (something); encroach on: "infringe on his privacy".

The usage in the constitution is the same as definition #2. To have our privacy "infringed" on does not necessarily mean that all privacy was taken away, it just means that some of it was taken away. So, likewise, any law that summarily prohibits all citizens from keeping and carrying (bearing) arms (weapons) of a certain "commonly used" type is a violation of the 2nd Amendment as that is "Infringement" by definition (the supreme court has previously allowed restrictions on "firearms not commonly used for self defense or militia purposes". Clearly, some of the firearms covered in this ban are very commonly used for self defense AND militia purposes, so I don't see how this law could be considered constitutional by any stretch of the imagination...especially the portion banning the possession of magazines over 7 rounds.

World's First Linux Powered Rifle Announced

bobcat7677 Re:Do Not Want! (272 comments)

You obviously didn't read the article. It's a bolt action rifle so you need a human to load a round a fire it (don't start with how they could make a semi-auto version...there are a couple reasons why they chose a bolt action for this system.). And it comes out of the box with video streaming capability. The thing even comes with an iPad to view the video stream. What you are talking about though is "remote controlled hunting" which is illegal in most US states, and can get you in in US federal prison trouble if you try to do it with a semi-auto rifle as that, by definition, turns the rifle into a "machine gun". Reference: http://en.wikipedia.org/wiki/Internet_hunting

NPD Group Analysts Say Windows 8 Sales Sluggish

bobcat7677 Re:It isn't Windows 8 I find to be the barrier... (269 comments)

It's obviously designed to be a touch interface and using it with mouse input can be very frustrating. I have been shopping for a basic laptop and I see this over and over on customer reviews when I look at models that ship with Win8 now. They usually go something like "Great laptop. But Windows 8 is difficult/horrible/doesn't belong and you can't downgrade this version. I wish I had gotten one with Windows 7". I totally understand that feeling as I felt the same when I tried Windows 8 on my existing laptop. It seemed like it would be a nice touch interface, but that became extremely annoying since I didn't have a touch screen and using the mouse to do the "touch screen stuff" can be cumbersome and is not intuitive at all. You get used to it after a while, but I think it would remain annoying to most people and seems to reduce productivity.

NYC Data Centers Struggle To Recover After Sandy

bobcat7677 Re:Poor Planning? (231 comments)

The tanks are required to be below ground by the fire code. I think the better question is why put big data centers on a low lying coastline/island and/or a city with a giant target painted on it by every anti-american, anti-establishment, anti-whatever whacko the world over. Data centers belong in places with low risk of natural disaster, war, terrorist attack, riot or really anything that brings the police out.

Major Internet Outage Affecting Users In The Northwest US

bobcat7677 bobcat7677 writes  |  more than 2 years ago

bobcat7677 (561727) writes "A problem with the Sprint network is causing major headaches for businesses and individuals. Sprint claims the issue started with a fibre cut in Wisconsin, while the concentration of users affected seems to be in the Northwest US.

I had to VPN to another local data center that is not using Sprint routes to have a stable enough connection to post this story. When on my local connection, most of my packets get lost being routed to Tokyo, Kansas or Australia for no apparent reason."
