When I realized that's the Balanis who also authored Advanced Engineering Eletromagnetics, I was like whoa, must be a real privilege.
"Trying to do the same in much of the US is likely to result in being chased off with a gun."

this is a real problem in the West of the US. There is so much land fenced in that it's really difficult to do cross country hiking. When I visited Scotland it was a breath of fresh air to see how easy it is to get around there.
Well, not pumping the capsule with 100% oxygen definitely helps too.
One of my favorite tidbits of history, introduced to me by the Poldark stories, is that of the Basset family of Devonshire. They are one of the few aristocratic families that has an intact patrilineal descent going back to the Norman conquest. Which means that in 2066, they will have maintained their family holdings for 1000 years.

Thank you. Would you be so kind to write a blog post about this?

This would seem to indicate that there is a huge oversupply of coders. The fact that knowing how to code wasn't even considered important in the "Startup School" curriculum does as well.

I agree, but I guess maybe the issue is that too many people have started to feel like they have nothing to lose regardless.

Wow, so well written. I really enjoyed that!
I recently had a mentoring session with a person going for a lead position, but they haven’t been an “on paper lead” before. I had to talk them through it but I think they understood at the end how to position themselves.

I do not find most people know how to adequately fill in the dots for people on the other side of the table because businesses aren’t always terribly forethcoming about what they are looking for. If you’re not an excellent communicator (which many people in IC roles are not) it can be easy to not pull sufficiently the information needed to position oneself sufficiently.
> simply are showing this as a legitimate threat

The issue is with the perspective, China is certainty a "legitimate threat" to the US, at least from a technological perspective, the problem is that China IS NOT a threat to the rest of the world or at least not in the same degree it is to the hegemonic power of the US, meanwhile the US indeed IS a technological and military threat to countries around the globe, so wherever the US and its agencies gaslight about China being a threat, it is always too funny, when you remember that the US has all sorts of military bases, drones subs and spy satellites deployed, not to mention it is already spying digitally on the entire planet (this conversation included ofc)
Given what I've been reading in this thread, it seems like if some employers are going to think that you're going to lie, there's no point in sharing your salary. And the salary that should only matter is the one you'd accept to change companies.
I remember this from a professor in college as well. I spent weeks modeling an antenna element and then once I had it made, he brought out the copper tape and a knife and tuned it to closer match what we wanted. It is humbling to see this kind of craftsmanship in technology.
Some thoughts on the initial images from /r/spacex (great community):

1. The orange smoke [1] is the color of Nitrogen Tetroxide, which is the hypergolic fuel that Crew Dragon uses. The normal reaction in the Draco engines in the Crew Dragon is Nitrogen Tetroxide (N2O4) and methyl hydrazine (CH3(NH)NH2) [2]

2. The prior grey smoke might mean the engines were already firing for the test, which would rule out something like a tank loading error or something else with the ground crew.

3. Boeing had a hypergolics + Launch Escape System anomaly and it pushed their program schedule back 6 months. [3]

4. Eric Berger (Reporter for Ars Technica) indicating it may have been a serious incident. [4]

> And UL was kind of a joke from having dealt with them personally.

UL may be a 'joke', but it does keep a lot of sketchy electronics out of the market (at least in the US). In my personal experience dealing with them, bad hardware design is more to blame for a bad experience with UL than the UL process itself (which, is brutally long, but just might be for a reason..)
Yes, I have heard of the Clearances. My point wasn't: "I haven't heard of this". My point was that the framing was bizarre (again, do you understand what university is for? It sounds like you don't) and the implication was that there is one "truth" that which must be indoctrinated...the fact that you don't seen to comprehend this reinforces all of these points.

Nope. I would suggest looking on Wikipedia if you want to know more (you don't even seem to know when the Civil War happened) but briefly: Cromwell invaded and imposed rule from England, when he was deposed Scotland was (nominally) independent again AND THEN the Act of Union happened. Weak.

There is nothing preventing "ordinary folk" (again, this suggests an inferiority complex) owning land. Anders Povlsen has acquired masses of it, the English have acquired lots of it, CoE has acquired masses of it...go to an land agent and they will tell you where and how you can buy.

Yes, everyone who disagrees with you as a baddie. Whine whine. Bigotry is only evil if someone else says it. Lol.

EDIT: You have edited in "this is snark"...it isn't "snark", it was a statement of fact (to be clear, the post I was replying to said that there was no perception about unfairness...that is demonstrably false, if I take your house that may seem fair to me but unfair to you...this should be obvious). If you are going to disagree, do it on content.

And sorry but when someone says: "Scotland's second biggest problem is England", I don't think that wins them the moral high ground. Replace that with a race/gender/religion. Kind of shocking that you think this isn't bigotry.

"and is not welcome here"...put down your pitchfork, stop gatekeeping, communities thrive on the ability to take criticism from outsiders (apparently, I am the evil outsider), they fold under spineless leadership that tries to drive out inconvenient thoughts.
Maybe you should make some specific proposals. Otherwise your statement is totally empty.

Really? How? The day before the Lion Air crash Boeing stock was just a hair under $360 a share. Today it's at $380. How exactly is that punishing the shareholders?

It is how you talk about failure when it is another part of your engineering characteristics and not something that causes fear or shame.

Another reminder is why you run tests. They don't scare away failure by existing, they are there to catch failure, doing their jobs exactly as intended.

It will probably result in a delay of any human spaceflight by SpaceX until the source of the source of the problem is removed. (not the particular issue that caused the anomaly but the systematic issue which didn't find it before it happened on the pad)
It's not their fault that Google's permission system isn't fine-grained enough. Besides that, what trade secrets are you going to glean from a contact list or calendar entries? I doubt even your meeting agendas are going to contain much info.
"Anomaly" implies this is not the case.
I used to love to bowl. (10 pins.) I wanted to be a professional bowler in my youth. I remember reading about Irwin Jacobs when he bought AMF, the giant bowling manufacturer.

The Bowler's Journal (the leading bowling industry publicaiton at the time) ran a cover story on Jacobs, complete with a tuxedo and high-rise office. Jacobs assured us that he was in bowling for the long term, bringing more resources to AMF so it could raise the sport to new heights.

Of course he broke up AMF shortly after, extracting profits from the pieces and pretty much ruining everything good about the company.

I didn't think well of him.
Great book, this is how I learned NNs
I used to be in the camp that cared a lot about formatting, but over time realized that it's more my OCD than any practical reason.

At this point, the only reason why I like consistent code formatting rules is because they prevent bickering between people who have strong opinions on how things should be. When there's a rule, even if people don't like it, they abide by it. When there are no rules, everybody who thinks that there should be rules starts bikeshedding what they ought to be.

But as far as code quality goes, I don't think it matters much.

There's still a distinction between describing why the code is the way it is, and why it evolved the way it is over time. The latter is what commits capture.
No, anomaly means there was an outcome which was not expected. It says nothing about how many tests they were going to execute (if any), what the unexpected outcome was, or what the lead test engineer ate for breakfast that morning.
Hmm. We had one candidate who had an exceptional resume and walked us through an open source project that he wrote. It was an adequate substitute. We wouldn't compensate for a project like you mentioned but the real goal of the exercise is to gain an understanding of how you approach a problem and use your tools.
Development infrastructure like Jenkins has no business being on the internet, so my preferred "second factor" is a VPN, secured with machine specific certificates that offer only VPN connectivity, but not SSH or anything else. This means even if a developer's Git or SSH key is floating around your infrastructure no one without VPN access can get at it, and if a developer loses a laptop there's a good chance you'll hear about that in time to revoke that machine's VPN certificate before anyone has a chance to use it.
Excellent, looking forward to hearing from you!
You can negotiate for a reasonable increase but if an offer comes in at half of what you're making, negotiation is a waste of time for both parties.
Right. It means exactly what it means. Actual test did not match expectation. Thus, there is an anomaly. Sometimes that means "boom" and sometimes that means bad sensor and sometimes it means the result was outside the margin and they need to do a thorough analysis before retest.

Unless you have large chunks of code moved around wholesale, you can usually track all commits that touched a particular line of code. I've done that while debugging codebases that were over a decade old. And seeing those commits was incredibly helpful, despite the code itself being heavily commented.
Ok. I'm not sure what they consider modern in the c++ world
There are quite a number of cross-platform GUI libraries out there, and they've been options for decades, without performance loss.

AFAIK, the only thing that Elecron brings to the equation is the ability to use web languages that more people are familiar with to work in it, instead of yet another language. This trade-off came with a pretty huge downside in the form of a bloated parser though.
I think you can explain it even more clearly with smooth relative shifts, rather than sharp bump functions. I made a quick demo: https://www.desmos.com/calculator/rfaqogkbmy

Drag the sliders for w and n to change how step-like the sigmoids are and how many are combined. The purple lines are the sigmoids, relative changes at each (regularly spaced) position, which are added together to make the blue approximation to the red function. You can change the function f(x) to see how it handles other possibilities, including piecewise/discontinuous ones like "{x<.5: 0, x>=5: x}".
These laws put no restrictions on what candidates can say, absolutely none whatsoever. They just affect the employer side of the conversation.

Employers in California (and NYC and a few other places) cannot ask about salary history, but they can ask what salary the candidate wants, and the candidate can decide on their own initiative to share salary history info. If candidates share such info voluntarily and unsolicited, employers can use (and verify) it.

So any candidate who wants to can say those market rate words you quoted. Similar phrasings that answer the still- permissible "what salary are you looking for" question also work fine.

One of the most likely wordings to get a good outcome without losing respect is: "I want whatever number is market rate for someone with my skills and experience at an employer like yours. I'll make inquiries through my professional network to learn what's appropriate so that I can consider your offer in the correct context, and I'll try to be fair to the company as well as myself in the resulting negotiation."

Notice how that doesn't depend on salary history info at all.

For California specifically - not currently the other places with this type of law - employers must
also share the "pay scale" with "applicants" upon their "reasonable request" (these phrases have been clarified legislatively in sensible ways). So that's even more help in avoiding discrimination while staying honest.
Sorry I'm in mobile now
Given a camera focused on the players, given commentators on set, given known histories of the players, their recent successes and failures, their past encounters against each other, given stakes, given a ticking timer and the psychological effect of time trouble, the psychological effect of a tricky move, the psychological effect of exhaustion after a six hour game, given knowledge of the players' different playing styles and my preferences... I can tell the difference between human chess and computer chess.

My enjoyment of chess is not simply a scalar function of chess moves.
'Anomaly' is a polite way to say 'failure', no matter how fine the semantic wrapper. Failures are to be expected and OK and it's good that they happen during testing rather than operation, but there's no value in euphemism here.
A simple rule of thumb to prevent this: if it made past code review, it stays, because, by definition, nobody cared enough to notice it and/or call it out.

(This goes only for style guide violations, of course, not behavioral changes.)
From a NASA systems engineering handbook:

>Anomaly: The unexpected performance of intended function.

Good or bad, major or minor, an anomaly is when reality does not meet engineering design and expectation. It just happens that in spaceflight the most active time is the most dangerous time and most anomalies result in fireballs when your engine is lit as there is not much room at all for error.
Only French basques.
In case it's relevant, here's a 1958 NASA film on the hazards of the propellants (various hydrazines) and the oxidizer (nitrogen tetroxide) that were used at the time. As mentioned in another top-level comment, the Crew Dragon uses nitrogen tetroxide as an oxidizer.

In large companies, there's another factor to consider, which is that if you're a few years into the company, the stock grants that you received a few years back and that are still vesting now are now possibly worth a lot more... your total yearly comp increases quite a bit if your company stock did well for the few years you've been with them.

I think it's because it looks like you didn't read the article, which explains repeatedly that this is a theorem of universality. Any continuous function will work, and sin is continuous.

Check this out: https://www.desmos.com/calculator/rfaqogkbmy

Try changing f(x) to "sin(x)" or whatever you like (e.g. sin(10x) may be more interesting). Then drag the sliders for w (how step-like the purple pieces are) and n (how many pieces to add together). The function f(x) is red, and the approximation is blue.
Wiki says no.

We can't/see no need to keep them in place short term.

https://en.m.wikipedia.org/wiki/Geosynchronous_orbit

A perfectly stable geostationary orbit is an ideal that can only be approximated. In practice the satellite drifts out of this orbit because of perturbations such as the solar wind, radiation pressure, variations in the Earth's gravitational field, and the gravitational effect of the Moon and Sun, and thrusters are used to maintain the orbit in a process known as station-keeping.
I graduated 5 years ago and I still use it daily.
To a first-order approximation, the length is 1/4 wavelength per leg. However, that assumes an ideal conductor in free space. We rarely have the luxury to suspend an antenna a few wavelengths from the ground, water, buildings, and anything else remotely conductive. The way the antenna interacts with those things in the near-field affects its impedance and makes it behave electrically longer.

The common formula you'll see is: Total Length (in feet) = 468 / f (in MHz). If we suppose exactly half wavelength and do the unit conversions, we would expect L (ft) = 492 / f (MHz). So why do the calculators use the shorter length? It's an empirical compromise. Taking 5-10% off total length is generally what's needed to account for things in the near-field. The 468 number has been repeated enough that it's stuck. In practice, I almost always cut dipoles for a full half-wavelength, hook them up to an antenna analyzer and then trim them down. With as cheap as hookup wire is, I'd rather not take the risk of being too short and having to field solder a splice (not fun on ARRL Field Day).

There's not really a general formula for finding length. The physics is nothing more than Maxwell's equations, but many of the deviations from an ideal dipole come from interactions with the environment. It's difficult to measure and/or predict how the environment will behave, so you're often better off building the antenna and then adjusting it in place. And so we end up with empirical rules of thumb like L = 468 / f.

Antennas are one of the harder topics for amateurs, for sure. The theory is well-understood, sitting somewhere at the intersection of EE and physics. I'm lucky enough to have a strong background in both fields, but there's a clear lack of curriculum for amateurs without that background. This website at least seems useful for building intuition, so hopefully it helps you some.
Would much rather an explanation of what the code does to achieve this miracle.
Why is nobody in this thread mentioning the the 800lb gorilla in the room?? That is, in a capitalist system the homeless, mentally-ill, "problematic", disturbed, troubled, etc are simply considered useless and frankly purposefully pushed to the edge with the hope that they will simply...die. That is the fundamental truth in any capitalist society - you either deliver value or you perish. Who will pay for these people to be housed, treated, re-integrated, educated, fed, etc in times of largely non-existent real economic growth, where almost 80% of Americans live paycheck to paycheck?
https://www.cnbc.com/2019/01/09/shutdown-highlights-that-4-i...

The answer is, of course, nobody. For all the talk about caring for the homeless and in general those who are at the bottom of society, the sad/brutal reality is that society as a whole does not want these people around. So, they keep getting squeezed and in turn keep squeezing the few who are willing to help them or at least listen to their woes. That is what is giving the author PTSD, not interacting with mentally ill every day. Namely, the realization that a sizeable minority of the US population are simply considered junk and are purposefully pushed towards death.
But she only saw part of the story. The scarier truth is that almost 80% of Americans (all those people living paycheck to paycheck) are only one job loss or chronic illness away from the same faith. More than 2/3 or all banckrupcies are related to medical bills.

https://www.cnbc.com/2019/02/11/this-is-the-real-reason-most...

And when you add to the above that empathy in general has declined by almost 50% over the last 2 decades you'd have to be a psychopath not to start getting PTSD symptoms or at the very least a very serious case of clinical anxiety disorder or even psychosis.

https://www.reddit.com/r/psychology/comments/bedj96/the_end_...

Just think about this for a second. If most people around you do not give a rat's *ss about you even when you are doing OK, what happens if you meet with bad luck and go downhill??
Anxiety, depression, bipolar, psychosis, suicide, etc - all of these can be explained rather easily by the simple reality that most people live in terror every day to be surrounded by people they do not care about and those do not care in return.
It's not that amazing if you think about it: a culture fostered around anything doesn't mean that something has to be particularly and objectively good. Consider Pop music for example. Also with modern technology and distribution channels, there's nothing to stop brits from getting good at critiquing tea. Full disclosure: I'm a British expat, but I know a logical fallacy when I see one!

The poor in the article though had it very different. They couldn't order a new tea online, nor trivially discuss tasting notes with people in China, Japan or Taiwan for example; I think that's worth noting.
They are just controlling the W_DISABLE signal which the firmware uses to control the actual radio hardware. It is _not_ a hardware switch in the since that the power is shut-off.
