And great targets. A hill will get you a bit more a 500ft hill will get you 27.4 miles. throw in clutter and jamming and you will still be facing an low observable standoff missile hitting you. Once the standoff missile crosses the radar horizon the target will have 3 minutes or less to engage. AAA will not be effective since they can not use VFR for targeting. Your only hope is optically guided SAMS or optically targeted AAA and if it is foggy or at night those might not even be effective. VFR radar was dropped for microwave for many good reasons. Now it can prevent a sneak first strike but in battle it will be degraded very quickly because of it's size. It is kind of like HF backscatter radar in that respect.
Lower frequency radars "VHF" radars have several issues. 1. They are large. The longer the wavelength the bigger the antenna. Easy to spot and hard to move. 2. They must be on the ground so you have a small coverage area as far as low altitude targets go. 3. They are not accurate enough for terminal SAM guidance.
And yes stealth aircraft tend to optimize RCS for ingress and egress but they still have a small RCS from other profiles. The exception may be close to straight up and straight down. Take a look at the B-2 and I think you will see that it probably has a low RCS for 360 degrees.
"Also, an airplane that is stealth head-on is much more visible to radar from the side or bottom." But all that visible. "today's stealth technology has been defeated by going back to WW2-style radars with lower frequencies (someone forgot to check, so this was discovered by accident)."
VHF radar can not be used in SAMs You can not fit a VHF radar in a SAM or an AWACS much less a fighter so it will be limited to LOS and have a very large footprint. You take it out with a low observable low altitude strike weapon like the AGM-158. You still want the low observable part to keep the AAA from locking on to the strike weapon. In theory you could have a VHF radar tracking a target and then getting an IR guided SAM close enough to hit the target but that is not that simple of an issue.
Ok then an 8TB 2.5" HDD for $90. Even at today's prices I see HDDs as more of archive storage. You put large amounts of data like media on them. Also if IOPS count then you will just keep adding spindles to an array.
Not really. Take out the radar and the SAM systems are blind plus it still must be LOS for the target and the launcher. Plus how do you network them? RF? that gives away locations and can be jammed plus limited bandwidth if you are not in LOS. Fiber optic and or copper? Makes things a lot less mobile and fixed targets are easy to hit. Also networked radar does not defeat stealth. Bi static might but again that is a complex problem.
"Very soon flash will be cheaper than rotating media," said Siva Sivaram, executive vice president of memory at SanDisk.
I can hardly wait. Just as core replaced drum and ram replaced drum I am excited to get rid of spinning platters. The day I can get a 3TB SSD for around $100 will be a great day. Of course it might be possible to get a 40TB HD for that price by then...
Probably does not apply in this case. Getting aerial imagery for the use of law enforcement would be seen more as a supporting role than law enforcement. Kind of like using military radar to track a hijacked airliner over the US or using a the road on a military base as a shortcut by the police in a high speed chase.
I tend to agree that it is unlikely. I was just pointing out that it would not go right to a full exchange. You may see a nuclear deapth charge , bomb, or antiship missile used at sea or on a manmade island would be the first step.
" The current pacifist constitution is a model other countries should look too, not one that should be abandoned" Which was imposed on them by the US after WWII. "More than that, being pacifist has kept Japan safe for decades. " I think you will find that it is more that the US military has kept the safe for decades.
No what will happen is a tactical nuclear weapon will be used on say an invading fleet. It would not start with a full exchange of weapons but with an F-18, F-16, F-35, F15E, or B-2 dropping a B-61 on a fleet or a man made island in South China sea or a Chinese sub using a nuclear torpedo to attack a US carrier.
"The ESP 8266 is more than capable of integrating with higher level controllers." Yes but if you are going to use BLE, OpenCV, WiFi, and wired ethernet then a Pi would be a better choice in case. Both could do the job but the pi offers a richer feature set than the EPS 8266.
And their is a human in the loop that launches any missile.
And no you are wrong. The Captor mine is a good example. You set it on the seabed and it waits for a ship with the right signature to pass over it. It then fires a torpedo that homes in on the ship or sub.
"There are other missiles of this capability so seeing a blip on radar but what is it really? Enemy aircraft or something else like a civilian airliner or a UH60 carrying UN officials? " Actually modern radar systems can identify enemy aircraft at long range now. How they do it is classified but the F-18,16,15, 22, and 35 can all do it. Even back in the day you had IFF which told you if it was a friendly or not. And you do not see all that many FF air to air problems with US systems. Now ground targets are a much different story.
For a basic door opener yes but maybe they want it to include a BLE interface to the cell phone or even using the camera and Open CV to have it identify the car and automatically close the door. It really depends on the feature set you want but the ESP 8266 could do a simple open the door when you use an app on your smartphone.
At many colleges the football team actually makes money for the school.Sometimes they make a lot of money for the school. It paying $1,000,000 a year to a head coach is not all that dumb if the team makes a $10,000,000 dollar profit for the school.
This is more enterprise than consumer. File systems like ZFS can use SSDs as a cache for spinning platters. On a modern server you may have a system that uses RAM as a traditional disk cache followed by an SSD or array of SSDs as a second cache layer, and then disks as the mass storage. It can even be pretty smart and using and ageing system to move files in and out of the SSD cache based on when they were used last and you could even tag some files to always be in the SSD cache and others to never be in the SSD cache. My question is simple. Will the benefits of these tall multi-platter drives be worth the cost? Sticking with the tradition drive sizes gives you economy of scale.
Remove tin foil hat and read the story. "“Project Shield only uses the data we obtain (such as logs from the Project Shield servers) for DDoS mitigation and caching and to improve the Project Shield service,” the company added." Seems like they are aware of what people might worry about and have posted a policy statement to put people at ease.
I agree. Things like sales on computer parts, bicycle parts and cloths, devboards, cars, travel deals, motorcycle helmets, jackets, and parts I am fine with. Even things like local events like car shows, rv shows, air shows, fairs, concerts are also good. Just do not make me wait forever for them to load and they must not be animated, have video, or audio elements.
These are failed spysats. The program to build them was cancelled when the cost went up and improvement over existing systems went down. These are left over hardware from the program and where offered to NASA. It is not the first time after all NASA got hardware like this. NASA flew the YF-12a and the F-107 for many years after those programs shutdown.

The problem would be getting that Army to Japan or for that matter Taiwan. The Chinese navy is not up to that task.

Really I want one if I can get an SDK for it. Not to cheat but to write my own apps for it.
$50 and a nice big screen is kind of cool.
What about Open Office Base and Libre Office Base?

Much the same as other AntiShip missiles including the Harpoon.
Guided weapons have been around since WWII. Torpedos are a prime example
