    Question Better ways to add a 2nd NVME to a single-slot mainboard?

    Whatever you do it will slow down to USB adapter's speed.

    Question Bought ram on ebay, shipped with bubble pack between cardboards (not in box), no antistatic bag, return?

    So I bought a stick of $25 DDR4 3200 CL22 to match what my prebuild PC for my dad come with. The seller was a noob and sloppy, and he just wrap it in some bubble pack and then tape cardboard paper on the outside. I am a bit concerned that it may work fine now but then it will start having...

    Why do tech companies waste money on office space?

    Not a manager, but I've been working 20 years and know why office is important in some situation. Depends on the work type. Not everyone has their attention span at work when they are alone, people influence each other at the office so that keeps them focus on the right thing. If you think...

    Whom is still rocking an Athlon / Phenom II (even X6), or a Core2Duo/Quad? X58 users too.

    Running a PhenomII X4 555T (something like that) black edition with MSI E880-G45 and 8GB of DDR3, not overclocking. That thing must have been 7.5 year old now and was a $110 combo from MicroCenter.

    Celeron G3900 with Asrock Z170 motherboard with 7 NVMe SSDs?

    It would be even less than server type of workload as I do not need any processing of the data and send out to ethernet, so in theory I can cut the traffic by half but double the amount of drives I load. I'm just wondering if the CPU side's cache size and frequency matters on these kind of work....

    Celeron G3900 with Asrock Z170 motherboard with 7 NVMe SSDs?

    I'm trying to see if this sounds crazy or if it is actually reasonable, please forgive my stupid questions because I'm still using Phenom II X4 and OCZ Vertex 2 at home so I'm a bit obsolete to begin with. Recently I got a project that I need a build to test some NVMe SSD prior to deployment...

    Is there any source for legitimate vehicle reliability ratings?

    http://longtermqualityindex.com It is the most objective one I have seen but it only shows older car with major issues like engine and transmissions. Sent from my Nexus 5X using Tapatalk

    Mirroring 2 OCZ Vertex 2 50gb as my boot drive?

    I got 2 retired but rarely used OCZ vertex 2, 50gb and I'm thinking about using it in my machine as a boot drive, upgrading from 2 Seagate 7200.7 PATA that I was RAID 0 with (2 x 120 gb). I know OCZ is unreliable but with mirror I think I can take the chance. With the AMD motherboard raid...

    What SATA 6Gbps SSD controllers support 3D TLC NAND?

    SLC is easy, if your controller support MLC it would support SLC for sure. In reality it is really the firmware that supports them, and whether it needs additional processing / IP in hardware to support the extra work for 3D and TLC NANDs and more channels to compensate for the slow down using...

    Kind of feel badly for Sears

    The real estate is actually the curse that destroyed them. Anchored to a dying mall and liming along instead of closing them for a box store layout like Target is what kills their store front. I'd buy at Sears to avoid the mandatory delivery charge from HD or Lowes back when they have appliance...

    Should I consider working for a company where their stock is tanking?

    If you get a good paycheck it is not a bad deal, but if you expect the stock to go back to $25 or $100 then I wouldn't. I've worked for a well established tech company that went from $100 to $8 and back to $30 then $50 then $80 then $64 and got bought out at that price. My initial sign on stock...

    The 2015 Annual ATOT Income Tax Thread

    The 2015 Annual ATOT Income Tax Thread

    Hi guys, it is great to be back on ATOT after 2 years away (kids). Previously I was using Taxact for federal and then FTB's online site for state, but this year Taxact no longer let me put in a lot of the forms (capital gain, amt, etc) unless I use the plus version for $20. So for a married...

    Cell Phone signal in a metal building

    In theory like they said you can cut slots of certain length (1/4 of wavelength?) to allow wave to get in, but in practice you need lots of it or much bigger to get good reception as you are likely not having a direct line of sight to the tower. If it is a small "building" it would be easier to...

    Why so few clockless CPUs?

    I was taking a class back in school that the professor hijacked into teaching asynchronous circuits. The biggest problem is the result of calculation would not only be unstable, but the uncertainty increase exponentially as the logic complexity increase. It also is significantly larger in size...

    Intel in Talks to Fab ARM Cores! (Rumor)

    CPU instruction set is no longer relevant today and it is easy to port. They do use x86 for OSX so they know how to do it anyways. The point is, for the same amount of die space, x86 is not scaling well for power and heat vs ARM on the same node size (i.e. 22nm). There is a reason why everyone...

    Intel in Talks to Fab ARM Cores! (Rumor)

    Anyone today using x86 for phone is suicidal. Even if you can get it for free or at production cost from Intel or AMD the power consumption and heat will kill your project before it ship. I'd imagine Intel is already fabbing ARM cores for their Infineon Wireless chips or planning to do so, and...

    Vision sensors: Where to even start?

    What he and others were saying is latency, and I agree with you, that if you use 320x240 resolution in B&W you can use a PC to do it let alone a real DSP or GPU. The problem they have is they can't even find the right sensor yet. If they spend the same amount on signal processing of the analog...

    How was your college experience?

    Undergrad, I was a full time student with only a small part time job and it was fun. Didn't drink or party but did have a lot of fun hanging out with roommates, chasing girls, working out, games, and I loved the classes I was taking and my major. Grad school, I was working full time and doing...

    Political indeed, and unless we are at war with China I don't see a reason to outdo them even if they go to Mars on their dime. Now about one way trip, I'd imagine a lot of older people will want to go there even if they were to stay there forever afterward. And I'd imagine by impossible to do...

    Vision sensors: Where to even start?

    As Jeff7 said ground loop could have problem reading traffic up stair and down stair, and cutting ground loop into a concrete parking lot can be a bigger problem due to cost and building integrity. Pressure sensor is the most reliable one if you don't mind replacing it once every few months /...

    Basic circuit theory

    In steady state they would be identical and encouraged. In analog / RF types of application the transient behavior could be different and you will likely have different possible path before reaching steady. It is not just going from point A to point B on a K map, but in a circuit with a lot of...

    Vision sensors: Where to even start?

    You totally can do it with a DSP or other high performance processor. The algorithm design and tuning is the key. The implementation of the hardware and software, not as much. It is like saying you need to build a suspension bridge before you evaluate all the options (i.e. non suspension bridge...

    Vision sensors: Where to even start?

    Do you have any more additional requirement throwing out here? I didn't know money is so tight that a mere $800 sensor would be a problem, let alone 4 of these $800 to cover 2 dimensional measurement of the object. Also how much space do you have to install these sensor? I think if you have...

    Vision sensors: Where to even start?

    PsiStar is right, defining the object is the key here and to distinguish the vehicle from other stuff you can either define by dimension, capacitance (metal?), weight, reflectivity (color, surface direction, shape, etc), or a combination of the above.

    Vision sensors: Where to even start?

    Now it is a lot more clear what you are trying to do and IMO it is actually much easier to do without camera based recognition system. A light curtain should be the best choice when setup correctly. IMO using the right sensor means something that can tell you the pixel count of the item...

    Vision sensors: Where to even start?

    Looks like you are doing some sort of vehicle tagging or vehicle camera. The best way to approach this IMO would be magnetic sensor on the ground like those seen in front of an intersection. Knowing an object to be mainly metal would give you an advantage on that. Combine it with other sensor...

    Vision sensors: Where to even start?

    To begin you need to get familiar with vision processing yourself or hire someone that can. Like all the people above said your requirement is too vague. In my previous work and school I've seen system that does what you said, but they are usually done at $1000 or so because they are small...

    The Rise and Fall of AMD.

    I also agree that both Intel and AMD's biggest problem is ARM. Usually monopoly like Intel is broken not due to a strong competitor, but because the entire market has shifted away. If binary compatibility is no longer important, then Windows is no longer important and therefore x86 is no longer...

    Japan aims to abandon nuclear power by 2030s

    I think they should focus on getting a safe and good reactor out (i.e. Fast reactor with passive safety) instead of chasing after fossil fuel. Unless they consider running power line to Siberia and China and buy electricity from them, they have no alternative.

    China Pulls Almost Even With 1930's Japan

    To be "fair", Russian analysts said if US is not involved Chinese navy and Japanese SDF are pretty even in terms of power, but if US is involved, then China will lose by a wide margin. What it doesn't said, is if the goal is to destroy infrastructure of Japan instead of occupy Japan, will...

    Oh look.... GMO corn causes tumors in rats, according to a study

    Will the Republican Party exist in 10 years?

    They can compartmentalize their candidates in the House and maybe senate by having some far right and some moderate people, but when you have a presidential election, no one can get a candidate that satisfy all the fractions. If Obama is not black, I'd imagine a lot of those "far right" tea...

    Romney Campaign Expecting a Loss in the Presidential Debates

    Romney already lost when he screwed up so badly early on, and gave Obama the ammunition to attack. Rebate is not a single day event, it is not a single contest but the grade of a final exam of a class you have taken, your grade is too bad to recover if you never do your homework and skip the...

    The tax rate on the rich is not the problem, it's the loopholes
