For some reason, my first thought when I saw this was to think back to this other recent post: https://www.scottsmitelli.com/articles/ideal-candidate/ I feel like these are linked in some hard to describe way.

I'm not sure what the current state of the art is, but for the longest time it was pretty common for USB peripheral ICs to have small flash devices attached to them in order to be able to store VID/PID and other USB config informa

Back in the bad old days of version control (thinking of VSS here), I was overall pretty satisfied with how the check-in/check-out mechanics worked for Word docs and the like. In this case you have the benefit of the sequential workflo

Agree completely. I think Vanguard's UI is trying to send the message "if you're logging in you're doing it wrong".

The StateMover concept sounds pretty interesting and is almost like the reverse of the integrated-logic-analyzer approach that the major vendors have adopted in their tooling. I assume that in simulation land that your debug environment is

I don't think that long lines scaled particularly well with increasing number of LUTs and clock rates. All the black magic voodoo that goes into matching prop delay for resources like that tends to be applied to clock distribution. At

Something that I think is missing in the discussion here with regard to payment methods is: know your market segmentation. If you are targeting b2B (i.e. large business), there are going to be a lot of circumstances where credit card paymen

Am I reading this right that the standard remote ID broadcast is specified as "something in an unlicensed band, everything else about it you figure it out"? Isn't the point of this to be interoperable with other receiver syst

I know that this doesn't directly address the question you're asking, but to give an idea of the order of magnitude of the effect: the Doppler shift in frequency rounds to f_carrier * 2v/c. In the case of anything with "

As an aside: it looks like the timing diagrams in this article were created with a tool called WaveDrom. I've used this tool in the past and been impressed with what it's able to do in terms of creating nice timing diagrams for di

I have been through a similar process myself a couple years back, and just wanted to say that this is a really good effort in trying to tame a beast that doesn't really want to be tamed. Lots of experimenting around with write_project_

I think the heart of what the article is getting at is represented well by the following quote: "To let GPUs blossom into the data-parallel accelerators they are today, people had to reframe the concept of what a GPU takes as input. We

Day trading has a specific definition in this context (can't remember if it's SEC, FINRA, or some other acronym), and refers to the buying and selling of the same security with a single day. That $2.5k Fidelity account will go out

I spent a few minutes poking around their project scripts, and it looks like that the design file you upload back to EC2 is a post-routed design checkpoint, which is an interesting choice... I'll bet that they are doing partial reconfi

I think the parent comment to yours (or at least the edited version) is right, they are almost surely XCVU9Ps based on the logic element and DSP counts. The ram numbers listed in the product table are embedded memories (BlockRAMs in Xilinx-

To add to this - a lot (maybe all?) of the functionality that is described by the concept of "overlays" maps to the design and implementation of the programmable logic in a coprocessor system. To use Xilinx terms, this would be th

I would be careful of trivializing the last point that you made. Things like extremely long design cycles, environmental requirements, expectations of value-add engineering services, product lifetimes etc. make the auto market different in

In addition to the procedural issues already addressed, let me point out that airspace systems are extremely complicated from types of users, given the mix of commercial, GA and military traffic, and that adopting a new common standard appl

I think the author got a bit confused, as the next paragraph (quoting the VATSIM ATC) clarifies this statement... in the example given the ATC instruction requires readback. "Roger" is not what the controller is looking for in tha

A couple of general ideas to help you scope the solution space: - If you can do something with the part still in-circuit (i.e. the PCB assembly itself is still functioning), that's probably a preferable way to proceed. For instance, if

I will never forgive the Verilog powers that be for allowing the 'reg' keyword to describe "things that are not registers". But joking aside, the differences between VHDL and Verilog are minor in this context. And one pe

My best advice: synthesize early and often, and spend the time to poke around in the synthesis schematic viewer - Webpack still includes this I believe. It's a great way to compare what you wrote in code to the logic you intended to im

Having been through SYR recently - the doors are pretty annoying. When I was there, they had a bunch of signs telling people to go through in groups, which was hilarious as 1) the door midpoint area is about the size of one person plus thei

When you take the timeline of the history of the planet Earth into account, there was a not so distant past where an artist, musician, etc. could make a living based solely on the support of a single benefactor. It seems as though the past

If you haven't already, it would be worth your time to read Player Piano by Vonnegut - the setting is very similar to what you describe above, and it's a pretty interesting take on those themes.

Gold is a very significant part of electronics manufacturing, especially high end/high rel work. A couple of examples are plating on connectors and switch contacts (corrosion resistance) and ENIG PCB finishes, but there's a lot more where t

I think you are confusing the right to public transit with the right to transit with any commercial carrier through any engagement of your choosing... Which is unfortunate, because I agree with your point but I don't think the law backs you
