Personally I just factor in 10 days for my project and have a board made with pcb assembly. JLC is so friggin cheap it isn't worth it to me to bother with doing stuff on perfboard anymore. Last project I made was a UV lamp for curing resin and it was like 8 days from submitting the order to having a finished board in my hand.
Personally, I have some test/dev setups that I know work, either STM32 based or since the chip shortage a few espresif or rp2040 based boards. If I need to output a clock for example, I can just bitbang it and when I need a more permanent circuit I just spin a board.
I find having about 100x 1/10/100/1k/10k and a bunch of electrolytic, ceramic caps (.1/1uf mostly), along with components for some common circuits (like an ldo and buck/boost). I also have a bunch of cheapo premade buck converters that I can use whenever I need voltage conversion.
When the Canadian government arrested a Huawei exec who was ignoring Iranian sanctions and lying to US investigators, the Chinese government arrested 2 Canadians as spies. Authoritarian governments fucking love to arrest people on "espionage" charges, since it is hard to prove and they can pretend to not be able to share because of national security.
If you want or require mass production of electronics or motors, it's fairly difficult to have done in the US for competitive pricing (or in some cases, at all).
ASML is a really good example.
There were many, many reasons factories moved away from the US, one of which was the profit margins on goods, which actually is complex and directly influenced by the way taxes/accounting/finances are done in corporate America.
Don't get me wrong, greed has been a major, if not the major motivator, but there were so many people either asleep at the wheel, or actively driving us towards the outcome we have today.
Combat ranges are like 250-300 for a10 and maybe 500-700 for the 35. The big reason the 35 outranges the 10 is they calculate intercept missions as the combat profile vs the a10 operating in much more dense air in a CAS role. I would be willing to put money the range increase is negligible once you put it in a similar CAS mission.
When I worked at a huge company, I found that most advisories from state department quite accurately portrayed the risks in country. I would often look at state.gov and then talk to my local security people and they were close enough to be valuable to most travelers.
Ironically this might be the straw that breaks the camels back, when you lock up people on business trips, the companies tend to not look on that very favorably.
Take new salary and add business overhead costs of taxes, business insurance, benefits... add this to your salary, this is your yearly loaded costs.
Take your yearly loaded costs and divide by how many weeks you want to work... for example, you want to take 6 weeks off per year, then subtract that from the weeks in a year. This is your weeks worked.
For example(with made up numbers):
Let's say you make 100k/year, want to take 6 weeks off, local business taxes are 25% and insurance is 1k.
((yearly_salary * taxes) + fixed_costs) / weeks_worked / days_in_week = minimum_day_rateI'm not saying that the 35 isn't an excellent platform, nor am I saying the A10 would be a great asset in a conflict with china, but saying the f35 is a drop in CAS replacement for the A10 is kind of missing the larger picture of what it's used for today.
I am of the opinion that the f35 is a gerber multi tool and while it's super versatile, it doesn't do everything as well as purpose built platforms. The obsession with a one tool fits all is kind of silly. In every category, the f35 is objectively not the winner, there are faster fighters, fighters with greater a2a payloads, CAS with better loiter/payload capacity, bombers with better capacity.
One of the primary goals of CAS should be the ability to stay on station for extended periods of time. Part of the likelihood aircraft are on station is directly related to the cost to maintain and maintenance requirements. F35s have huge costs and require a significant amount of maintenance.
I could see a use of the a10s as a launch platform for 200-500lb loitering munitions to get them in range of frontlines, but using them for anything in the pacific would be suicidal.
Their bigger systems look reasonable on paper, but I doubt they would be up to the task of dealing with high end comms in an actual combat environment. They can barely keep them alive in Ukraine and from what open sources are reporting are either not very effective or deployed in such small quantities to be effectively nonexistent for the majority of areas seeing combat.
Sure, Iran was able to down a stealth drone years ago by messing with the electronic nav systems, but it wasn't like there was actual combat happening, and I don't think they have repeated that since then.
The problem is that it's really hard to take action on large corporations. As a consumer, if I wanted to seek remedy for say, false advertising of ingress protection on a phone, it would cost hundreds of thousands of dollars in legal fees. Without a significant war chest it's almost impossible to hold most companies to account as an individual, and the agencies supposed to be enforcing these issues either won't or can't enforce the laws on the books.
I used to buy dell outlet servers (which is their refurbed gear) all the time for folks who insist on dell, they end up being about 20-50% of the cost of cloud pricing if you are utilizing it with a full workload. Their stuff also includes a 3 year warranty with next day support, so it isn't very risky buying a refurbished server. There have been times where I found deals where the components could be parted out on ebay for more than the cost of the server. If you don't need support, there are tons of used servers on ebay / craigslist where you can get deals on 1-3 year old hardware that are good enough to purchase multiple spares.
For example, you can purchase a 2x 32 core server [1] for ~11k from the outlet store with next day support.
If you are running 24/7, with 64 cores over a 3 year period...
Server Cost / Years / Days in Year / Hours in Day / Cores = Core per hour cost
11000 / 3 / 365 / 24 / 64 = $0.0065/hour
If you wanted to go supermicro [2] with somewhat less reliable support, its a similar story. It would be a 1u dual 96 core (192 cores) box w/ 1.5tb memory for around ~30k. 30000 / 3 / 365 / 24 / 192 = $0.0059/hour
You can recoup your hardware costs within the first year vs. running in AWS if your workloads are high enough to justify the hardware expense.[1] - https://outlet.us.dell.com/ARBOnlineSales/Online/SecondaryIn...

They used to be the app I would point to for awesome design principals for iOS and Mac. The V8 release has made the UI more cumbersome and it feels like a half baked release.
The one bright spot is they have improved their windows version quite a bit and I admit the team based manager is useful, if expensive.
When I work from vacation, remotely, whatever... since I already have the "non-ideal" setup down pat, I either work from a coffee shop or from the place I am staying, but I don't have such a massive adjustment since I am already trained to be productive in a perfect environment.
It's been like watching a badly written tv show.
I really want to see an open motor control peripheral that could be used in robotics or UAVs, it's amazing how ubiquitous they are, yet rarely are very integrated like other controllers.
Think about how many billions of devices there are where you can't get simple a pinout diagram for the main CPU. I would argue only a tiny, TINY, percentage of any Linux devices actually have CPUs/SOCs/SOMs with sufficient documentation to look at from a hardware design standpoint.
Many places would develop on centos or scientific Linux and then when it went into production use RHEL, since they were effectively 1:1 ports. So yea, I imagine there are quite a few orgs who might switch.
Buy a product with a CC. All of the half dozen to dozen vendors involved in the transaction will generate data about you and sell/trade the data to other people.
Sure, LN might have some really good profiles, but there are so, so many companies doing the similar things.
With no effective data ownership or privacy legislation in the US, it will continue to be that way.
