That's single event upset (SEU). The other radiation issue is total dose. That's when charge gradually builds up in insulating gates due to ionizing radiation. It's permanent, and eventually reaches the point that the transistor is always on so has a permanent fault. One of the factors is collection area, so larger gates are not less susceptible because they have a larger collection area. But if they run at a higher voltage that can make them more tolerant to total dose.

Same with me when I was a teen and all my friends had motorcycles, several ending up being basket cases.

They can even be dispersed using mortars and artillery, like what has been done in Ukraine recently with butterfly mines.

All the discussion here seems focused on mitigation of upsets. What about total dose? Clever architectures and error correction don't mitigate that. Effective shielding is impractically heavy. You really need total dose hardness at the process level and that severely limits your choices and performance.

What are people's opinions on crossbows as supplemental defense weapons? They lack range and ammo is not compact but they are quite stealthy.

Pretty bad answers in some cases. Keeps repeating contradictory statements. I asked "Will the Thai baht fail." It kept repeating that the Thai baht is pegged to another currency, and then that the Thai baht is free-floating and not pegged, and then again that it is pegged and then not pegged.

Have you ever served on a jury? My three times were eye opening. Very few of my fellow jurors had the slightest ability to perform critical thinking. Most paid no attention to the jury instructions and simply voted their biases. I can't imagine how bad they would be as civil leaders.

Regarding your point number 2, I've been having this debate over on Twitter (ha) about how much those who remain are saddled with extra work. I've been through a few layoffs in my career, though none as large as this one, and what usually happened was those of us who remained ended up with less work. That is because the ones who were let go were almost always low performers whose work usually needed a lot of review and redesign by the more competent ones, which was more work than just doing the whole thing over from the beginning. In some cases when it did cause a large burden to the remaining employees the project left behind by the laid off ones was left to die. And that often was the right answer since the low performers had so often been shuttled to projects that weren't very valuable to begin with. With no visibility into the Twitter case I don't know if there is much of the same effect that I experienced, although I am reading a lot of opinions on HN and elsewhere that some of the groups that have been decimated should have been killed off long ago.

He also did Secret Life of Components which is very good. I used it as part of a Design & Technology course for my home school.

This is the mode I am in with my kid. Got him started on making and coding at a very early age and he took to it. He's 12 now and doing some significant things with Python, 3D printing and Arduino; the latter two were new to me so I picked up a couple of cool hobbies. He's an avid reader so I keep filled a pipeline of good books for him, and I read them first which means I'm filling in gaps in my own education of books I should have read in high school. We went to home schooling when Covid hit and that has worked out very well.

But... I am older and I retired early (tech was very good to me) so I have full time to spend with him. That doesn't work for people early in their careers.

What if aliens did not perceive distinct objects, but rather that everything observable is part of a greater whole? Would they need counting numbers?

Isn't fly ash quite high in radioactive material and a source of indoor radon when used in house construction?

Or they took the advice of an authority figure who suggested drinking disinfectant to cure a certain viral disease. JK

What were the voting results in those prior referendums?

"large portions of the residents were forced out by the war, especially the residents inclined towards Ukraine"

This is the first sensible answer to a question I asked elsewhere (only to be down-voted for asking a question) about why the insistence on the referendums being a sham. Much of the Ukraine-inclined population fled. Much of the Russia-inclined remained. So the post-invasion vote is heavily pro-Russian.

The effect of lowered account-wide CTR on CPC is something that has been experienced by a lot of people who have run Adwords campaigns. I saw it discussed a lot on forums about affiliate marketing. They always said, whatever you do, avoid the "account slap" that comes if your CTR plummets. I saw it myself on more than one account.

Maybe it isn't causal? But the correlation is pretty near 100%.

Not legal for sure. But there are things that are done informally that are similar. Like at one company where I was a hiring manager we used head hunters heavily. Most head hunter companies are bad (in my experience) but the better ones try to match good candidates with good companies. They have extensive networks with other head hunters and often see the same candidates repeatedly. When they see red flags they cull those candidates or maybe present them to the "bad" companies (the ones they aren't concerned about damaging their relationship with).

Another method is that hiring managers at different companies may have good relationships with each other. Not competitor companies, but adjacent. They may call around and ask about a candidate. You can never say anything negative about a candidate; that's just asking to be sued. I think many (most?) companies have a strict policy that you can only say if a candidate is eligible for rehire or not, nothing else. So you talk in vague generalities, never about the candidate, only about the general hiring process. Something like "Company policy prevents me from giving any recommendation whatsoever, so my advice is that you should always be very careful in your hiring process" versus "Company policy prevents me from giving any recommendation whatsoever, but an effective hiring process can yield great employees." You might argue that a judge would see right through that and say it is obvious which candidate you are recommending and which you are panning. But it's so nonspecific that your lawyer can strongly push back, should it come to that.

No confusion. I've been through this with several accounts I helped manage. Once an account has a history of low CTR the CPC goes up. Starting a new campaign doesn't help; the CPC stays high until you can get the CTR back up. And that costs dearly.

But again, that was years ago. Things may have changed.

Once you have thousands of ad impressions with very few clicks, it takes thousands of new impressions at a very high CTR to get your overall account's CTR back to something reasonable. And now that your cost per click has skyrocketed, even if you can get a high CTR for the new impressions your cost has skyrocketed.

"Never listen to a google ads rep if they call."

Excellent advice. I was helping manage an Adwords campaign for an online shop, only had search ads turned on, was carefully watching and tweaking ads and managed to get a pretty decent CTR which had a big impact on cost per click.

I was in a different time zone (15 hours ahead) than the company. I went to bed one night and next morning I checked and found that our CTR had gone through the floor, was way less than 1%. And as a result our cost per click had sky rocketed from 10 to 15 cents to several dollars.

Turns out that a Google ads rep had called the office and convinced someone to turn on display ads, which killed our CTR. Our advertising budget was depleted, our Adwords account had received the dreaded low CTR slap which meant it would be very costly/impossible to get CTR back to a reasonable level. We were done with Adwords.

Things may have changed since then. It was years ago and I haven't touched Adwords since.

Anyone remember On TV? Their audio was modulated on a subcarrier that was easily demodulated with a single chip PLL. And the video was just mixed with a sine wave at, I think, the vertical scanning rate - super easy to mix in a 180 degree out of phase sine wave with a crude manual potentiometer adjustment for amplitude. I built one of those decoders and although it was a bit unstable and would lose sync now and then it worked well enough.

I read comments like yours with interest because I used to be a hiring manager at a big aerospace company where I ran a department doing some cool stuff - signal processing, novel computer architectures, VLSI and WSI chips. We always recruited at top schools and got a few engineers from MIT. They were brilliant, but good grief they were lousy engineers. One guy was obviously a genius and generated great ideas constantly but he could never get anything done. Week after week he was always two weeks from finishing his next milestone...and never did. Another guy told me that, as his boss, my job was to make sure he was happy to come to work every day. I told him we would both be better off if he did a good enough job to make me happy every day. And another said he didn't think there was any work worth his attention at the company, yet he was still there scraping by year after year. Small data set, but I was discouraged from recruiting there after going 0 for 3. I wish I had hired someone like you knew.

Similar story. My dad was a carpenter doing wood frame construction in southern California. He later got his contractor's license - better money and less physical labor but he still did some construction. I worked summers as a laborer for him when I was in high school. I never got injured but he had injuries now and then. The one that did him in was a fall due to a broken rafter that broke his heel. He could never walk normally after that.

Even when he was young he told me to make money with my brain not my back. He would also tell me to look around at a job site and ask my why I thought there were no old roofers (falls), or painters (paint fumes), or plumbers (solder fumes).

Some of my high school friends got started in construction via my dad. It was good money and they were not the college-bound types. A few years later I heard one of my good buddies cut off his thumb with a Skilsaw. By now most of the others are probably broken down.

That was an eye opener for someone who was thinking of setting up an instance. Obviously there are risks to federating posts from other instances, but I wasn't ready for this.

I wouldn't think it's that one. They definitely have huge influence, but the country that I think of as having actually infiltrated the US government is a different one in that part of the world.

In Thailand there isn't dual pricing for food. But there is for entry to many venues. It is institutionalized by the government - for example, the entry fee to national parks for non-Thais is 10x the Thai price.

Yep. I used to do technical sales support. I would come in after the sales manager had broken the ice and arranged for some of the customer's technical team to listen to our proposed solution. But the sales training we got told us to always sell at the highest level possible, preferably the person who would sign the purchase order, not lower level technical people.

That didn't always work out. We sold a lot of stuff to Hewlett-Packard and they always forced most of the decisions down to the engineers. They would rarely let us talk to the people who could sign the purchase order. The sales people didn't like it much since they didn't have the control that they were used to. But it was kind of great for all of us technical people because we could sit around with the HP engineers and talk about technical stuff without a lot of sales-speak getting in the way.

Not sure, but owning lock picking tools might be illegal. But as I have since learned, many locks are easy to pick with a paper clip.

I was a manager in a nearly identical situation. I had 5 engineers working for me at a remote office. The "curve" had not been used in past years. Now they insisted on applying it. Since 4 out of 5 had substantially exceeded their goals it would have been a lie to state that any of them had not met expectations. So I told my boss no, I'm not doing it. You can take whatever raise you planned for me and spread it across my direct reports (unstated was that I would almost certainly quit as a result). Or you can fire me for insubordination. He ran that back up the chain of command. Apparently I wasn't the only middle manager who refused to do it, as senior management ended up rescinding the order.

Moral of the story: If you are a middle manager then grow a backbone.

Somehow my 11 year old got interested in lockpicking (maybe happened upon LPL?). So I got him a kit consisting of a clear-bodied lock and picking tools. He had mastered it within a couple of hours. Then he taught me. And since them we've picked every pad lock and door lock in our house. The biggest and meanest looking ones turned out to be all bluff and the easiest to pick. I hadn't thought that it might be illegal where I live. Maybe better check.
