go to work for Boeing or Lockheed. you might be surprised by the sophistication of missile seekers. and countermeasures. note that what you see on TV in the current conflict may be several generations old.

Beliefs can change based upon experiences and time. It's called wisdom.

one just has to identify how society determines the "rich", and how much to require. both of these are very difficult questions. i want to tax the rich! yes, i do. lets take a reasonable share and deal with societies ill's.

in general, a software dev anywhere might not realize the flaw. but an systems engineer or other aircraft and flight controls engineer would notice it. and they should have, when the requirements were written. and again when each require

there are not person-specific clearances, but there are person-specific non-clearances; e.g. there are lists of people and companies that you cannot do business with because of them being non-compliant with ITAR.

You sub contract out hardware assemblies (and software) when you start feeling market pressure and your cost has grown to be competitive. Then you find, as a prime contractor, that you are still responsible for the product. You still have

RedHat has a realtime kernel. it is available from the mirrors. Currently also available from CentOS. last time i checked, it would not load the NVIDIA driver. YMMV. if you are in the < 120hz range, then it will probably work fine for m

no one confuses gear from MFJ with "high quality". cheap stuff, that whets your appetite for the good stuff. and yes, i have an MFJ tuner and the 20 meter QRP rig they sell. it is a ford or a chevy, not a lexus or a mercedes. (

you write an ECN (Engineering Change Notice). these stack up against a given part number (controlled by a drawing). then the drawing gets updated. this is where any conflicting ECN's get discovered. Note: ECN's were how things

HP 8640B puts out a clean and precise waveform. wonderful piece of test equipment from the world of RF. put a short wire on the output, and tune it to 146.34 (for a second). bang, the local repeater will kerchunk.

yeah, absolutes never apply to every situation. it is possible to go down in expertise, but not up. sometimes "fortran in any language" can be a viable approach depending... note i didn't say a the best approach.

from a different angle: "non original team" might have higher defects, but i propose that "non original team" without process or time to understand the code base would be more accurate. changing people requires a time in

it is probably because the new devs know so much more and are able to identify and communicate problems in code that others have written. write code for the center of the bell curve (at your organization). the bottom will never understand

some problems cannot be fixed. they either need to be cancelled, or they will run to completion using 2 or 3 or 4 or X times the budget and schedule. the real value is identifying these projects early. but identification is not near as dif

preemptable, priority based scheduling is your solution. if you are in a latency sensitive environment, the "fairness" or "throughput" of the scheduler are not things you care about. next most important is 'pinning&

when i was first exposed to ada, early 1990's, the language was unusable. compile times where excessive (like hours). machines of that era were slow and had small memories (4MB was a common size, and more than 1 CPU was a luxury). i

i would say it is interesting they did not use ada. best language every designed for this problem domain.

Note this applies to the manufacturing,not the design. It is actually a wonderful analogy with software: * to a first order, cost of the materials in an airplane are proportional to the weight * at design time, the weight of the aircraft is

reliability is giving the right answer. availability is being ready to give the right answer. cloud services have poor reliability and good availability.

all ham transmissions need to be identified on a regular interval with a callsign, assigned by the FCC. it is trivial to look up a callsign, and see if it exists.

roll with it. the best ideas come from improvements. both the idea and the improvement have to be there. it is a complement for others to parrot your ideas. also remember, technical skills are only part of the picture; others may be demons
