<p>The post seems to be in line with some of my own direct observations. I've been pondering recently whether for many devs the use of AI is the death of the mental model.<p>We all interact with systems through mental models, but if many devs are just prompting claude when something doesn't work, they might read what claude found, but lose out on the exploration, debugging, and work that builds and reinforces the correct mental model and discourages the wrong one. And if devs are missing out on the mental models, will they actually be capable of driving efficient solutions to problems as the mental models get worse.</p>

<p>Lots of folks are commenting on the internal dynamics, but the other part that didn't resonate with me was actually the what happens next part. This may be an overreaction on my part, stemming from watching lots of engineers suggest expensive solutions to relatively minor issues. And it's a mistake I've made myself before as well, I started in telecom with very strict standards for availability, so it's hard to beat out of me the desire to look through the most minor alarm for a potential problem brewing or get to a root cause of the most minor incidents.<p>And maybe this is just a part that the article dodges, but for something described as non-catastrophic, I would suggest that there shouldn't be a presumption of changes. In my view there should be an assessment of the risk of re-occurrence, and if it was a near miss, what is the risk had it not been a near miss. And then even should changes be part of the outcomes, how expensive are those to implement compared to whatever the issue was, and if they're too expensive compared to the risk, don't put resources into it.</p>

<p>Part of my maturing with getting older in addition to the above is that luck is a larger factor than most people are willing to admit. So I'm with you that GTM is just as important as engineering, but execution on all fronts is what tilts the luck factor. And with luck you get exceptions which is why you can get companies that seem to succeed despite themselves.</p>

<p>These tools are very common in non-nefarious ways for troubleshooting networking, and while vendors set up to serve this space solely as troubleshooting tools, I've also built my own that can sit on a network link and monitor for problems.<p>In my case it was for mobile wireless signaling traffic (all the coordination for creating a mobile internet connection, handing the connection off between towers, etc), and I'd credit it as one of the reasons you're mobile internet connection is so stable. When LTE first came out, myself and many others solved all sorts of bugs in the equipment and protocols by using or building these sorts of tools.</p>

<p>Not exactly acoustic but reminds me of a high school science project we had one year, something along the lines of put out a candle with a contraption. My partner and I rigged up a balloon to be popped by the candle, and the balloon pop blows out the candle. Probably not an original idea, but I don't think any other group in the class tried a similar approach. Worked like a charm.</p>

<p>I've seen this point in a few different places and I don't know that it's understood as widely as it should be.<p>So just to expand on why that's the case. As a net producer of energy right now, the US produces more than it consumes. This is why it get's pointed out, that as a net producer, the trade deficit with Canada is also a surplus (or reduction in deficit) on the other side with other countries. Yes it may not be the same physical barrel that is exported vs consumed, but in a fungible way they're commodities. If you separate out that portion, we (Canada) then buy more goods from the US then we sell. And that's also just the goods trade, not including services which the US also sells more of to Canada than the other way around.</p>

<p>Just in case any of the authors read HN, I'm getting a pretty crazy rendering bug on this page, where a bunch of the contents are redrawing up and down by a few pixels. It seemed to go away with resizing the width a few times, but I didn't look into it too hard. My page width was probably small on first draw. Incredibly distracting though and hard to read with the text moving. Using latest chrome, and it occurred on more than one page refresh. I didn't dig in beyond that though.</p>

<p>Sorry, I didn't mean to imply tariff's were the exclusive cause, just a reminder that an additional factor is large tax increases.</p>

<p>>It's basically, because everything else has gotten more expensive. Labor + fuel + wear and tear on equipment + raw materials.<p>Don't forget taxes (tariffs) have also increased substantially. Even if a supplier isn't paying tariff's, if their competitors are they can often just raise their prices, or their prices go up due to the supply/demand shift.</p>

<p>> The strict academic definition hasn’t followed the colloquial usage for a long time. Maybe ever:<p>This is my understanding as well, and as I recall the results of the research were also more nuanced than most people seem to indicate. So not only were the novices with a wider range of self-estimates, the average result of those perceived scores was still below the experts. So it was never that low performers thought they were experts (although this may show up in the raw results with some portion of the population tests), just that on average they perceived their performance to be better than it actually was. And the high competence group while overestimating their results, still thought they'd do better than the low performers.</p>

<p>And to try and expand on why an index would include a waiting period in it's rules, my limited understanding is it's to give the public markets time to follow the company and review several quarters of financial results to stabilize the valuation in relation to those results before getting included in the index.</p>

<p>I'm a little bit more on the fence with the work sample interviews having designed them and also interviewed through them. I've also done my fair share of "traditional" tech interviews, all at startups, never FAANG.<p>As an interviewer, I much prefer the signals generated through a work-sample interview. I'm much more confident in the hiring recommendation than I get from a 1 hour zoom session. However, if I look at teams that were built through the work-sample and zoom interviews, I'm not sure the outcomes were that noticeably better.<p>As an interviewee, I think I understand the frustration being on the other side has. With an in-person interview, I often have a good sense that I bombed the interview or something to improve on or replay in my head, less surprising outcomes. On the work samples it's harder to know whether you're making mistakes, or are being out-competed by someone putting in 4 times the effort to polish the solution beyond what their regular work product would be. Although I had one really good outcome where the work-sample interview really flagged the internal dysfunction of a company.<p>And then with both interview processes, I still think there is a really big unknown on what the false no-hire rate is, how much effort is getting wasted rejecting candidates that would actually fit the team.<p>So having to choose a process as an interviewer, I'm with you and would always choose a work-sample interview. On whether it should be considered the "gold standard", I'm much more hesitant, I think there are some limitations that are still hard to control for.<p>I do wish Starfighter/Stockfighter model had gained more traction, would've been interesting to see a recruiting company specialize in this and then seeding the interview results to multiple companies model work out.</p>
