The anti-duck-curve is actually really, really pronounced for east-west mounted bifacial panels.
The panels still don't generate any electricity at night of course, but other than that the output is an almost perfect inverse of the conventional equator-facing angled mounted panel output.
My next array is likely to be east-west vertical bifacials, as I need only a small amount of additional capacity in the summer, but could still do more in the winter.
We currently have:
- summer optimised array: almost flat, 15 degree, optimised for maximum power on sunny summer days, mostly runs our cooling
- winter/morning array. Points SSE, 65 degree incline. Gets great energy in the mornings, and on winter mornings. Performs surprisingly well in overcast conditions. Generates about the same power in midwinter and midsummer.
- winter/afternoon array. Same as the above, but SSW.
18kW total faceplate capacity, in reality we peak at around 5kW, but have that for about six hours of the day for 9 months of the year. Also means I can run three arrays on two MPPTs as the two tilted arrays are basically mutually exclusive as to when they make power.
The other reason for leaning towards vertical panels is cleaning. The flat panels accumulate a crust of crap (pollen, soot, dust) that cements on there fast, and requires vigorous scrubbing to remove. Kills 20% of the capacity unless I get up there with a broom every six weeks. The 65 degree ones I have not had to clean once, as stuff just slides off them.
That, and a pallet of bifacials is now cheaper than a pallet of monofacials.
The economics changed, it is now cheaper to put more panels East/West than having tracking ones as the tracking hardware is expensive. The tracking panels have the advantage to be put vertically in case of heavy hail.
Depends on what you mean by advantageous. Solar tracking setups are very expensive relative to a fixed panel one. They can produce more power per square meter via higher utilization but cost so much it makes more sense to just buy more panels if you have the space.
I meant advantageous in that the anti-duck-curve of these panels would only be superior compared to the duck curve of a fixed panel. But that it would be inferior compared to the (what I presume is) the very high peak of the regular-duck-curve of a traditional solar tracking panel, since the "tails" of the curve should be similar at sunrise/sunset. But I see now that solar tracking seems to have fallen out of favor due to the economics of how cheap panels are.
Absolutely but tracking is expensive relative to just throwing more panels at the problem.
But shading is also a factor. If you want to get unobstructed sun across the whole day, you need to be built on a nice curve of a hill? Or build just a straight line of panels?
1. Microsoft is not a "dotcom startup". We live in a different, much more consolidated tech world of companies that either balloon to become behemoths or are bought by existing behemoths.
2. Power and data centers can be used for other things than AI.
3. They might turn out to be wrong and not need the deal/power. For companies sitting on a shitload of cash that would be an inconvenience whereas not investing and then later having to beg for electricity amounts to losing the race.
Yes. Yes, it is a tragic event. Apart from it being simply morally utterly reprehensible, it is an extremely primitive and counter-productive way to fight against ideas and the messengers of those ideas.
Again, morally reprehensible and it doesn't fucking work. It only shows 'the other side is just as bad/worse', turns the messenger into a martyr, and galvanizes support.
> What is actually tragic is that spreading lies, as he did
Unlike many others, he invited anyone to the mic to prove him wrong. Hardly qualifies as lying. Anyone could have gotten to the mic and debate him. Sure, you may don't like his beliefs, but there is a huge difference between lying, and defending (even incorrect and unfounded) claims in public.
Even if he believed that himself, anyone who came to the stage to dispute him would receive death threats. Read the audience. He knew what he was doing.
Let me document five very serious lies from him:
1. On Facebook, YouTube, and Rumble, Kirk repeatedly promoted the false claim that the medical examiner who performed the autopsy declared Floyd had died of an overdose.
2. Ahead of the 2020 U.S. presidential election, Kirk spread falsehoods about voter fraud, and immediately after Trump lost the 2020 election, Kirk promoted false and disproven claims of fraud in the election.
3. Kirk called the public health measure of social distancing prohibitions in churches a "Democratic plot against Christianity".
4. In the 2020s, Kirk was a Christian nationalist who called the separation of Church and state in the United States a "fabrication".
5. Appearing at a Trump campaign rally in 2024, he said: "This is a Christian state. I'd like to see it stay that way."
There are innumerable more. For the record, the February 2023 Brookings Institution study found Kirk's podcast contained the second-highest proportion of false, misleading, and unsubstantiated statements among 36,603 episodes produced by 79 prominent political podcasters. [1]
Contrast it with the way in which truth is actually spread; it is by citing good-quality references.
> Even if he believed that himself, anyone who came to the stage to dispute him would receive death threats. Read the audience. He knew what he was doing.
This is far fetched. People who have sent the death threats are lunatics. If the number of people who are sending death threats is our new standard for the quality and importance of debates, then we should simply stop the debates. There are always unhinged people around. Where does it leave us?
> Let me document five very serious lies from him:
Sure. Some are maybe lies, some are his opinions, some are misleading claims, and the rest are his own beliefs. Still, anyone could have went in front of the mic and debated him for it. In my opinion, someone is a liar when they have a platform to lie, and no way for the public to engage, debate, and correct them. While Kirk's beliefs are very far from my own (e.g., I do not believe that election was stolen), I still think that what he did is needed today: speaking your mind, and being open to be challenged in public.
It is bewildering how the Republican voters don't realize that the party cares exclusively about those who fund the party, not about those who vote for it. The votes are gained exactly on the basis of lies. If the party actually cared for its voters, it would send all the non-immigrant work-visa employees back home immediately if they don't have a PhD degree in their field of work.
The footage I have seen universally depicts a cheering, entertained crowd that expresses nothing I could interpret as hateful towards anyone.
> Kirk repeatedly promoted the false claim that the medical examiner who performed the autopsy declared Floyd had died of an overdose.
Two autopsies were performed, and both involved at least one medical examiner. One of them found that fentanyl and/or methamphetamine may have been a complicating factor. But this is understating the case. Floyd is known to have taken a very high dose of fentanyl (https://www.kare11.com/article/news/local/george-floyd/evide...), which is commonly understood to be a very dangerous drug. The other autopsy, commissioned by Floyd's legal team, did not include a toxicology report.
> ... voter fraud ...
This is, of course, hotly contested. People on the other side of the aisle, from what I can tell, sincerely believe that the people "disproving" these claims are fabricating their evidence and/or ignoring supporting evidence.
Regardless, believing a falsehood to be true is not the same thing as lying.
> Kirk called the public health measure of social distancing prohibitions in churches a "Democratic plot against Christianity". In the 2020s, Kirk was a Christian nationalist who called the separation of Church and state in the United States a "fabrication". Appearing at a Trump campaign rally in 2024, he said: "This is a Christian state. I'd like to see it stay that way."
This is the same thing repeated three times, and it is an opinion, not a claim. He was not saying anything about what the law or Constitution provides. He was describing what he considers to be the general order of the society around him.
Many political thinkers across the spectrum have disputed that the US implements real separation of church and state, irrespective of what the laws and Constitution say. There are many simple ways to make this argument.
For example, giving preferential tax treatment or legal recognition to married couples is a clear mingling of church and state; government didn't come up with the concept, existing religious traditions (including paganism; I am not agreeing with Kirk's opinion on Christianity here) did.
For another example, from the Constitution:
> We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights...
It's hard to fathom, given the identities of the people involved, that "Creator" here refers to something other than the Christian God.
> There are innumerable more.
Again, the reliability of "fact-checking" institutions is in question. I have personally encountered examples of sites like Snopes and Politifact giving significantly different truth ratings to the same claim when it was made by different politicians. There are other sites out there dedicated to cataloguing such examples.

I did that too for a while, have since switched to Alienware 38" ultrawide, lgs vertical monitor on right ( LG 28MQ780-B) + MacBook pro on the left.
Ultrawide is quiet useful to have - especially with coding. E.g. It's nice being able to look at 2 files and have the project tree + tool window open simultaneously.
I think the key insight is that AI is (undoubtedly going to be) better at analysis and diagnosis than radiologists, but isn't yet widely deployed because:
1. The medical world doesn't accept new technologies easily. Humans get a much higher pass on bad performance than technology and especially than new technology. Things need to be extensively tested and certified, so adoption is slow.
2. AI is legally very different than a radiologist. The liability structure is completely different, which matters a lot in an environment that deals with life or death decisions.
3. Image analysis is not language analysis and generation. This specific machine learning part is not the bit of machine learning that has advanced enormously in the past two years. General knowledge of the world doesn't help that much when the task is to look at pixels and determine whether it's cancer or not. Now this can be improved by integrating the image analysis with all the other possibly relevant information (case history etc.) and diagnosing the case via that route.
That is, I do not think programmers will be "replaced". The job will just be different; people will come to rely on LLMs for their jobs, like they rely on search engines.
Likewise, you can probably hire fewer doctors now because Google appeared in ~2000, but nobody talked about them being "replaced". There is NOT less demand for doctors.

It also reminds me of the prediction around self-driving cars, which is 13+ years ago at this point:
I believe Hacker News mostly fell for the hype in ~2012-2016. And even though the predictions turned out to be comically wrong, many people are still attached to them
The world is indeed not static. That it hasn't happened yet doesn't mean it won't.
Predictions about self driving were off, but far from "comically wrong". Waymo's operations are proof of that.
And to conclude things based on the state of the replacement of programmers after only 2-3 years of ChatGPT being a thing is folly.
The reality is that AI has far fewer limitations and legacy cruft than humans to deal with. Don't get me wrong, I like humans, but our performance is very close to the peak of what it could ever be. That of AI not so much. Remember that AI has been evolving for less than 100 years and it is already where it is today. That took us/biology orders of magnitude more time.
The only real question is how fast it will replace (which) human labor.
If you look at his facial movements in the video it looks as if he is pretty actively using his facial muscles, 'trying' to speak while moving as little as possible (which would cause the clearest signals to be emitted).
If that is what is happening, to me it feels like harder work than just speaking (similar to how singing softly but accurately can be very hard work). It would still be pretty cool, but only practical in use cases where you have to be silent and only for short periods of usage.
My watch history has been off for almost a decade now.
They may weasel you into activating it via some other route that states in the fine print that they need to activate your watch history to provide [random almost unrelated feature].
