Argumentum ad hominem abusive does not belong in civilized discussion. I thought this was taught in elementary school. Since you bring up, I am curious as to where you got your education? It appears you neither understand my comment, and you also do not understand the marketplace.
It is common, and well documented that early production of ICs often have few chips in the highest performance bin. These chips are then sold at a high premium. Later the process matures, and often all chips go into the highest performance bin. To still get the premium price this bin used to command, many of these are now derated. There are also many other reasons manufacturers sell the same silicon with different rating printed on the part.
BTW, I have negotiated and sold products for military and aerospace use for decades. This includes ASICs and other in-house developed silicon.
The funny thing is that the chip manufacturers commit this same fraud daily. The same silicon is packaged in one package and labeled mil grade, and another labeled commercial grade. The price is often more than a magnitude different. Sometimes it is even the same package, just different print.
Of course sometimes there is different silicone, sometimes it is different temperature bin.
Funny that this is perfectly legal for the mfg. and when some clever reseller does the same it is fraud.
BTW. Companies with military contracts are often required to give the military "best price". With a seperate label for military version of HW, this is really profitable.
I would like to see the result of this study: -Take the DNA of all freshmen -Let the males and females smell each other one by one (in rooms so dark that beauty could be eliminated) and have them rate each other. -Let the males and females see and rate each others looks (like a criminal lineup)
Now throw all that into a computer to find correlation between DNA / smell / looks.
Now you can build the database to match couples based on DNA. A lot of interesting research could come out ot it too. Exactly which genes likes which genes, and which detest each other. Are there some universally unlikable genes, and what do they code? Are there some universally likable genes, and what do they code?
People without at least a 4 year degree have often big holes in their education. They may not, but it is hard to find these holes at the job interview. You can't ask "What do you not know"
So: Coders with good track record without a 4y degree might perform just fine. One benefit is that with a good salary, it is easy to keep them, as it is harder for them to find a similar paying job.
Witha 4 y. degree from a top school, they will have no holes, and also a great attitude and capacity for work. It is easy for them to leave for a new job. Same degree, and not top school, they have the same skillset, but are often less competitive and goal oriented.
A masters degree usually add little, but may solve a specific skillset your team needs for the next 3 month, like some algorithm.
A Ph.D. proves you can work under some demanding professor for many years and complete menial and often complicated work with little reward. So this adds little to code quality and volume but they do however seem to be able/willing to accept more complicated/boring/laborious tasks, and come out on the other side with it done.
So for the future coder: Get a 4 year degree from a top school, and complete a masters degree if you really like something marketable. If you don't get into that top school, use the time to build a superb resume instead.
Yes, the high-beams are not LIDAR jammers. They just make the high-beam reflectors a poor area to point the gun. High-beams are still effective in lowering the useful range of laser guns assuming the retro-reflectors like license plate are covered. The high-beams may emit 1kW/steradian, of which more than 1W is in the 904nm bandpass. The laser reflection is maybe 500nW. That is a lot of white noise to dig the signal out of.
It is pretty easy to stealth mod your car. I noticed that in all LIDAR training videos the instructor always picked out white cars. So start by buying a black car. You will also need a camcorder with night vision (the one you already have probably have a button for this) as well as a IR remote control(The camcorder might have the IR diodes built in already). A LIDAR operates at 904n, just outside the visible spectrum. Check that the paint is black by viewing the car at night with your camcorder. Black is usually black also in IR. Some other colors can also be black at 904nm. White and red are usually not.
Take a visible laser pointer and look at your car in the dark eyes only as a first survey. Especially front, but go all around. Keep it next to your head to see all retro-reflective parts. You will see plates and light assemblies are the big reflectors.
1. Cover your plates with IR blocking plastic. All new window material for construction has a thin metal layer for IR block. This will work fine. Use a frame over your plates to make them as small as possible as well.
2. Get rid of all retro-reflectors in the light assemblies. They typically look like tiny pyramid pattern molded into the plastic. The easiest way is to just sandblast the area until dull. Don't sandblast the outside. Take them of and sandblast the back. Test with your laser pen.
3. Look at the car with you camcorder in nite-mode. Remove or use a dull black touch-up paint to cover any strong reflections. If you have six large reflectors on the roof, just take them off.
4. Always drive with high-beams on, especially in daylight. Halogen bubs emit a lot of light at 904nm, and drowns the reflected laser.
The result is often >20dB signal attenuation. That means you will be 10x closer to the LIDAR gun before it gives a reading. If you have a laser detector, that is more than enough time to slow down. Usually you will notice that your car avoids any attention as there are better targets around you.
YADA (Yet Another Dumb Analogy): The power of all the computers in the world in the lifetime of the universe would not be able to calculate the outcome of this game.
And wrong. Let's try this out: 1. Enumerate all planets in the visible universe. (maybe 10^23) The entire universe may have 10^43 planets, but a sample space of 10^23 must be more than enough. 2. Each planet is a computer. set up the game on planet 1, and let it play out. 3. repeat for all planets. This should be very simple as you have a few billion years to set the game up on each planet, and the Stelliferous Era will last for 100 trillion years. If the proton decay theory is correct, you will have to finish your analysis within 10^38 years or so.
That should be easy too, as it should give you time to solve the quantum mechanical equation for the entire planet just by using a 4.77MHz 8086 PC, even if it takes a billion years to make the floppy disks you need to store all the data.
Just broadcast it on FM. You can easily set up a lot of radio stations multiple ways. 1. Buy some 0.5W (thats 1km) stereo mini Radio Station for $15 on ebay and hook it to: A. 4GB mp3 player $10. Download one flavour of music here. Repeat, and leave connected to the USB port. or B. One of many PCI or USB soundcards on your PCs and stream from Muziic, TubeRadio.fm, Grooveshark and Pandora(Only US) on some. 2. Get some FM radios. Both table, wearable and rack will work. 3. Enjoy
This may sound simple and low tech, but a) it is cheap, b) has a familiar user interface (tune knob)
Why are Comcast and other ISPs playing this trottling game anyhow? It is not like internet access speed is a limited resource. Gold, oil and water are limited resources, but bandwidth is not! It appears that this is more a marketing ploy worse than the artificial scarcity of diamonds created by De Beers.
Let's look at the different parts: ==Backbone== A fiberoptic cable in the backbone may consist of 1000 fibers. The cable is cheap compared to the cost of digging and terminating. Each fiber can carry 100 colors of 10Gb/s each. That is a whopping 1 Petabit/s. It is about 1 million houses in the SF bay area (5 million people), so one cable can give each house 1Gb/s.
==Metro== A single router (In actual installs probably more) can tie the backbone to multiple metro fiber nets. Cost is $100 for 1Gb/s. Biggest cost is laying fiber.
==Last mile== Many have fibers. 1Gb/s is cheap. With CATV distribution, you get 30Mb/s, and with DSl, 6Mb/s. Cheap mass produced ISP side equipment will trunk this into 10GB
Bottom line is that incremental capital costs to give a customer 1Gb/s is $200 in many of the more densely populated areas. This should cost the user $20/ month with both a good ROI on investments and a decent operational margin for the ISP.
You do not need any DNA analysis to figure that out. What do you think the troll did to the captured the princess, once he took her back to his mountain cave? And they did not call it the Stockholm syndrome if she ever was freed; it was called bergtatt (literally: taken into the mountain) or bewitched.
Unfortunately, the history is told by the winner; It would have been interesting to hear these fairytales as told by the Neanderthals.
The procedure I described, was the one followed in a Cupertino theater last year. They told me this was the procedure in the Bay Area. I am curious if this has changed.
The Sony SRXR220 has a lot of technology to prevent movie copying. The actual projector is only a small part of this. It has: -Enclosure Security System -approved receipt of secured DCP content. -Key security system -remote monitoring allows content to remain secure -Ethernet control to separate PC through secure TLS session -Sony exclusive internal watermark system -Lamp can be changed without having to enter secured area -electronic operator key entry system -multilevel security with operator roles -security management.
How this is used in a digital movie theatre: The movies are typically delivered on a HDD by a dedicated fleet of trucks operated by Dolby. The trucks have a secured cargo space similar to a bank transport. The Dolby employee carries the HDD to the secure area of the theatre together with the designated operator who opens the key lock to the room. The Dolby employee enters his credentials on the projector, ejects the old HDD, and inserts the new. The projector will print out a receipt of events, and both the movie theater operator and the Dolby employee signs the receipt, and keep a copy each. The truck leaves with the old movie.
There is no UPS "overnight delivery" or any third party touching this.
TFA has a Low res grainy 2D video, and the author readily admits: "Though it looks grainy, this and other video of the developing heart made by the Houston group are some of the best ever taken."
I think, and probably, it is very impressive to make a videothe beating hart of a tiny mouse embryo, even if it is grainy and 2D.
BUT WHERE THE HELL is the H.D. 3D video announced in the headline?
Series like the Office and books like the Peter Principle makes "the sour pill go down". By that I mean that it gives the average guy a safety vent for frustration and irritation created by random acts of management as well as corporate cruel and unusual operations. It basically lubricates the workforce, and while they think they are part of a large group ridiculing management and the corporate culture, the end effect of this effort is not change or revolution, but, au contraire, submission, acceptance and cooperation.
You are wrong. If you try to bend it upwards at the end, the centripetal forces will be high. 6km/s and a bend-radius of 1km will give an additional 3700g. At 450kg, that means that the load on the barrel sidewall goes from zero to 16MN or 1,700 metric tonnes m.e. Bedrock would not support that kind of local load.
0-6km/s in 1.1km give an acceleration of 1700g. Few things will survive this. Especially not people or satellites. Pretty much only uniform solid metal, such as a bullet.
Can you tell me what HW and SW version you are using. I installed the Kamikaze version, and configured the box to be a client following detailed instructions. WiFi portion OK. No routing. Then started a few threads in the forum. Basically told routing was turned off by default as a security feature.
I have written a the IP stacks for some routers, and consider myself pretty knowledgeable.
It is with a heavy heart and after having used the White Russian version for many years I say this.

OpenWRT is a great project, but unfortunately unusable in its current state. I have tried to use it on the Linksys WRT54GL, which is the default box, (hence 'WRT' in the name)
It is stable, feature rich, and *unusable*. I have for example not been able to configure the box as a client. It will work just fine as an AP
Looking for a solution, I installed an older version of OpenWRT, and this would only work as a client, not as an AP.
Expect the default setup to not rout packets at all. You have to configure the router carefully before it will work at all.
I have set up wireless networks with many configurations using other boxes and software, and never had this kind of trouble. It can certainly not be used by an average user.
It appears all resources are beeing spend to making it run on your casio wrist watch and other exotic targets while the old focus is lost. Seems like the 99%vs1% rule backwards: Target 99% of development resources to resolve issues faces by 1% of the users.
I do not think the compressed pulse can be transmitted any length in any fiber. Since the different parts of the pulse have different wavelength, dispersion would destroy the signal fast. Except maybe for vacuum. Traffic at different wavelength have many nonlinear interactions that are amplified if the signals travel all at one speed. Zero dispersion fibers (which is that only at one f anyway) have been abandoned for dispersive fibers to accommodate multicolor traffic.
This is a complete oversell on a normal everyday phenomenon. This is a simple compression of a lightpulse, and has been done for a long time. Dispersion usually smears out a pulse, but can easily, compress the pulse. There is no "bending of time" here. Look up "Chirped pulse amplification" and also "Prism compressor", and maybe "soliton".

The music industry's monopoly on distributing a very important part of the human culture is slipping away like sand between their fingers.
The grip they held on our culture has been choking, and made them very rich. It was solely based on cost of distribution technology.
Their effort, legal and technical, will be no more successful than the scribes effort to forbid the printing press a few hundred years ago.
