It entirely depends on how you want your homelab to work. I use a reverse proxy to set up subdomains for my publicly facing services because I find it easier and cleaner to assign a subdomain to each service, and I also like having HTTPS managed by a single point — a sort of single point of entry to the rest of the services. You'd have to decide what you want out of your homelab, and find and set up the services that yield the outcome that you want.

Instead of feeling the lumps on the skull for ADHD this quack use suspect brain scans.

Imo, it's nearly equally as suspect to claim that there is no correlation between SPECT brain scans and ADHD as saying that there is a correlation between SPECT brain scans and ADHD. The point that I was trying to convey in the post is that he is harnessing extremely sparse, and far from established, research to try and sell things to people. That isn't to say that there is established evidence to say that what he's doing is indeed bogus, there's simply little research to show that it actually works.

I don't understand the downvotes that this post has received (Currently 8 upvotes and 27 downvotes). The post is just reporting on a finding. It's not stating an opinion. Are people just unhappy that Trump's polls have increased so they're taking it out on this post? Is there something wrong with the article link? Is there some inaccuracy in the reporting? This feels like an example of shooting the messenger. Am I missing something?

I suppose there is the fundamental issue of people not collectively agreeing on what upvotes and downvotes should be used for.

Measured voltage is completely dependent on what is used as a reference. If you were to measure the voltage of a power supply set to +30V with a voltmeter whose leads were backwards (ie positive on the voltmeter connected to negative on the power supply, and negative connected to positive), then you would measure -30V. All this is to say that if you connect your 30V supply "backwards", you will have -30V. Now, there may be some circuitry in the power supply that only allows current in one direction, and it could be that it's able to source a different amount of current than it's able to sink, so be sure to check its manual.

I've tried -12V from psu i've got lying around but it didn't work.

I'd advise caution against arbitrary decisions with electronics — both for your own safety and the safety of the equipment.

Dr. Amen seemingly is a very popular "ADHD influencer". Many of his claims surrounding ADHD, however, are scientifically dubious. His main claim to fame is his work with SPECT imaging as a tool for diagnosing mental disorders [11]. Specifically relevant to this community is his advocacy for its purported use in diagnosing ADHD [12]; however, there is virtually no research to support this practice [1]. The only research that does exist (as far as I've been able to find, anyways) is a paper that he co-authored [2]. The paper does appear to show that SPECT can be used to measure observable differences between ADHD brains and the control brains [2.1], but one paper is far from an established body of supportive science for a medical practice that he touts and charges money for [5][10]. In addition to this, he also diagnoses what he calls the "7 types of ADD" [6]. This is not standard diagnostic practice in the DSM-5 [7]. He also operates an online store at brainmd.com where he sells many supplements that he has publicly claimed help with ADHD management [3.1], and he advocates for their use in his practice [4] — this is a conflict of interest; however, the supplements that he advocates for (that I have looked into) do have some research behind them [8][9], but they appear to not be well established treatments. I would also be wary of his research as he has openly stated that he doesn't respect the main body of psychiatric researchers, and that he doesn't wish to listen to their criticism [3.2].

I don't intend for this post to be interpreted as a trashing of Dr. Amen's reputation, nor do I fault him for trying to earn a living. There is simply a large potential for shady behavior given the context as a whole, and I believe that it is wise to be very cautious of his advice. I do hope that his research turns out to be beneficial, and not exploitative — I think that there is great benefit to be had from more accurate diagnostic methods, and improved classifications.

Unfortunately, a Linksys E8450 of mine has succumbed to the OKOD (OpenWRT Kiss of Death) (in case you are unfamiliar). From what I understand, it should be recoverable from it's current effectively bricked state. I've tried going through the process, but I haven't had too much luck, and I'm somewhat stuck at the moment, so I would appreciate some guidance. There's two potential objectives that I am hoping to acheive: the first, and primary, objective is to simply recover the router from its currently bricked state so that it can be used like normal, and secondly, if possible, recover the data, and configuration that was on it.

I have tried following this guide, but I'm not sure what I am supposed to do at the end. I completed the last step, but the router still isn't able to boot on its own. If I run boot from the U-Boot console, it appears to be able to boot into the OpenWRT CLI, but if I then reboot from that CLI, it shows the following error:

F0: 102B 0000
F6: 0000 0000

That same error is what shows when I watch the serial output of the router while it boots from the power switch.

My Linksys E8450 has succumbed to the OKOD (OpenWRT Kiss of Death). In case you are unaware, the OKOD essentially is the E8450 spontaneously dying. loss of power, or a reboot can lead to it completely dying — the lights don't come on, and it is essentially bricked. Afaik, it is currently unknown exactly what causes it.

Anyways, it may be possible to recover, and I am currently working on that, but should I not be able to recover it, I will need to purchase a new router. To that end, I am looking for recommendations for a new router that is equal to, or better than the Linksys E8450 (it must be well supported by OpenWRT).

I may just buy another E8450, but I am curious if there is a better alternative.

I encounter situations like this rather often where I am responding to a comment that contains many individual points/statements. I typically will respond with a single comment that contains a quote of each point that is being responded to with my response under neath the respective quote — and, sometimes, for added clarity, a horizontal line separating each response. For example:

Statement 1

My response to Statement 1


Statement 2

My response to Statement 2


etc.

I wonder if it would be better practice to have atomic responses to comments — create a single comment for each individual statement, i.e. spawn a new thread for each new atomic topic. This would allow scores to be representative of each specific response rather than an average of the total, and it may also help with clarity when reading through the comment section, as well as easing the creation of responses (not needing to rely on formatting so much). For example

Comment 1 in reply to comment with multiple points:

Statement 1.

My response to Statement 1.

Comment 2 in reply to the comment with multiple points:

Statement 2.

My response to Statement 2.

etc.

Jimmy the goat was rejected by his mother, so Hector Aubertin stepped up and became his best friend [...] "Everywhere we go, people are doing double takes," Aubertin told As It Happens host Nil Köksal. "He's probably had his picture taken easily 100 times." [...] "After the first week or so, we formed a bond. I literally cannot go anywhere without him or he just starts blaa-ing. He wants to know where I am. He needs to be with me." [...] So when it came time to go on a long-planned road trip to Edmonton with his daughter to visit her sisters, Aubertin figured he had no choice but to bring Jimmy along for the ride. [...] "We go everywhere. We go to the stores. We go to Canadian Tire. I can get him to come to me, you know. I can get him to lay down if I need to. He listens very well," he said. "He's like a dog, but twice as fun and just a little bit harder to train." [...] "He is absolutely my best friend. We go everywhere together," Aubertin said. "He's done so much for me."

The article says the following:

Linux 6.10 is introducing support for Trusted Platform Module (TPM2) encryption and integrity protections to prevent active/passive interposers from compromising them. This follows a recent security demonstration of TPM key recovery from Microsoft Windows BitLocker being demonstrated. TPM sniffing attacks have also been demonstrated against Linux systems too, thus the additional protections be made with Linux 6.10 to better secure TPM2 modules.

I'm a little confused with this article. Is it talking about implementing TPM parameter encryption? If so, does this mean that the TPM bus prior to kernel v6.10 was unencrypted? Will this kernel feature still require a patch to be made to software like systemd-cryptenroll? Are the sniffing attacks that it's talking about examples of MITM attacks like this? Does windows encrypt the TPM bus?
