Yes, but its usually not worth the time to include all parasitics in a model until you get to very high frequency work. Professional circuit/PCB designers already know roughly what the issues are going to be and can order of magnitude

by mbell 13y ago
That usually doesn't help as a large source of the problematic parasitics is contact between the part's leads and the 'grippers' inside the breadboard. Lead diameter, corrosion, 'gripper' spring strength, etc a

I wonder if it models the terrible parasitics of a real breadboard. I imagine it would be really annoying for beginners to build an IR receiver (or whatever) with the software, have it working perfectly, then try to build it on a real bread

Memory and '64bit math' aren't really the drivers here, 64bit archs generally have a lot more registers and allow better packing of SIMD instructions. Both can give large performance increases, particularly the later when a l

That wasn't GP's point. GP went on a very hyberbolic rant about 50" screens and how no one uses laptops. I agree the site's design sucks even when it works as intended and could scale better, but it works just fine on s

Not really informed here but I would venture a guess that 'perfect separation of concerns' causes a performance hit. In the backend web dev world you can usually suck that up by making the load parallelizable across servers, somet

Not quite exactly the same issue, not sure about all JVMs but the HotSpot JIT will replace concatenation with StringBuilder usage in many cases but it may not be ideal. For example it may create a new StringBuilder in every iteration of a l

Many companies cheap out on the supporting electronics. In particular single-link DVI is electrically compatible with HDMI but is limited to ~1920 x 1200 @ 60Hz. Basically instead of properly implementing HDMI they route a single-link DVI

I don't really disagree, but Linus's point, which I agree with, is that C99's implementation is 'better' but is still pretty bad, i.e. 'bool' is still a mask for 'int' and as a result array'

Put your menu bar code in your 'master' template (wherever you're defining the location for your ng-view). Use a separate Nav controller for the menu bar. It seems like your biggest issue is just data sharing, e.g. each page

Consider a simple bit mask operation, assume 8 bit ints for the sake of brevity: Prior to C99, assuming you use the mentioned typedef for bool: bool a = someInt & 0x02 'a' will be 0x02 if the bit is set. In C99, bool

For the most part I agree, I like what OSX does. However, there are edge cases which are infuriating. Have you tried to scroll through an HTML <select multiple> in Chrome on OSX? The only word I can use to describe the experience is

As a baseline it's limited to 100mA @ ~5V (150mA for 3.0). Devices can request additional power from the host, 500mA max for 1.X/2.X or 900mA max for 3.0. The host isn't required to be able to supply this much current, it c
