Not necessarily. You don't actually need the fluid to be perfectly sealed out, just slowed down a lot. This means that you could run it open but with very close tolerances and there would be almost no leakage. You just need to make the gap small enough for the leakage to be trivial.

As for magnetic alignment, that is all about maintaining smooth operation without losing efficiency to friction. Instead of a guide with friction you could use magnetic attraction to keep things aligned.

I haven't seen anyone else pointing this out but in my moments of dealing with suicide I found greatest relief in helping those who were hurting. Your nephew is going to have a really hard time and his dad is going to be under a lot of strain. For the first month or so people will be there, trying to help. In three months people will have moved on but he won't have. It will get harder.

Being supportive after the first month and helping your nephews dad cope is the most directly impactful thing you can do. By that I mean offering to have your nephew over if that is suitable, maybe having a family get together and actively including both of them, and making sure the dad has some down time.

Obviously it is not your job and so on, he needs to manage his emotions and deal with his grief, but of all the ways someone could help giving your nephew another place to be for a bit of the time can be a massive help. It gives the dad a break, strengthens the bond between you and both your nephew and his father, and it gives your nephew a less stressed dad. It also let's you keep an eye out for trouble and makes you a trusted adult.

Yep, critical thinking enhances all other intellectual pursuits. It is so easy to fail at the critical thinking stage and go down a blind hole pursuing something absolutely nonsensical because you didn't check your basic assumptions.

I would want kids to learn about the Monty Hall problem, do a little Bayesian analysis, etc. I think they could learn through trying to smuggle some lies into a paper and then peer reviewing each others papers and finding the flaws. Kids are way more creative than they are given credit for and they would find ways of sneaking things through we wouldn't ever consider. Making it adversarial would prepare them for interacting with the huxters and frauds that make up a huge amount of modern life.

Yeah, but there are many good options. Magnetic alignment can keep things from touching most of the time, maintaining very good movement without friction. Graphite is a great lubricant and works even in very cold environments, not to mention it will not be all that cold given the heat passing through the system. Redundancy is also a big part of the design, making failures much less impactful. And using sterling engines for the highest draw part of the lifetime of a probe with peltier style generators there for later would allow a failover to a solid state system at lower efficiency.

Blackmail material is only powerful as a threat. Releasing material from it makes the remainder less powerful. If you raise the stakes a little by adding some small details, an association here, a plausibly deniable link there, you can enhance the fear of the person on the other end of the blackmail without ruining the value of what you have. So depending on what people want they can get better results by keeping that information hidden.

On top of that most people who get dirt on one person get dirt on many people. You may want to take down one person but by if you release some stuff from the files then someone on the other side can burn people on your side. Mutually assured destruction will paralyse everyone.

As an outside to everyone I want all of it released because in my mind anyone implicated is either an active predator or someone who tolerates predators. But if you have paid good money to have a specific member of congress get into office and they are able to act in your favour then it doesn't matter if they have a D or an R, they are yours. It is very expensive to get someone who understands the game into office and under your thumb. Much better to prevent the whole system from becoming unpredictable due to lots of sudden new blood and to keep known actors in place. Members on both sides of the aisle want the files locked away forever, meaning they want to protect predators. The failure to act is a choice, not an accident.

To be clear, I am including foreign actors, massive companies, all sorts of people. If you have an asset that can protect another asset without knowing then you generally would do so.

I call it my bum bag, though I go with belt bag in polite company. That said, it us actually 3 bags one of which is first aid, then one for tech and one for wallet and similar.

Perhaps more modern ones, but the ones in my last and current laptops are both 18650s. 6 cells, 9 cells, you stack in series to increase voltage, parallel to get more capacity, so a 3s2p would have ~14V which is more than the required 12V for internal components, no boost converters needed. That said, now they do a lot of pouch batteries which are actually multiple internal pouches run in series to get the same sort of voltage but made with the chassis fitting them perfectly, no wasted space.

18650 is awesome, a good balance of weight to capacity. They are the standard cells used in laptops, vapes, small powerbanks, power tool batteries, and so on. They can also go into a fairly standard charger for AA and AAA batteries and give a lovely nominal 3.7V.

That said, pouches are better for inside a device like a controller. The weight of a battery is significantly influenced by the casing. A pouch is almost entirely capacity, a cell like an 18650 or AA is largely the metal of the casing. If you have the pouch inside the plastic of the device you can save that weight.

Dude, she was disclosing. She was telling you that she felt shame and disgust about how she was treated by this dude. He has a range of behaviours that when taken together paint a clear portrait. He was friends enough with that group to be sent those messages. He accepted that without raising it as an issue. He toubed her in a way she did not signal a welcome for. She was made to feel unsafe.

At he very least he should not be around her. It would be reasonable to not have him involved with her or any other women. To be honest, I would not have any man like that on my team. The only reasonable way your TMI comment could happen is as a prequel to getting a third party involved to document the situation. She may wish to press for his removal and you as a witness to her state after the incident should be providing supporting information, not shaming her.

Edit: So yeah, YTA

Benedict Cumberbutch is all I can see... Nicely done

Yep, so good to be able to recover. I love btrfs for this exact reason. Immediately before updates a new snapshot is taken and if I lose power or similar it doesn't matter, I can just boot to the state before the update. Linux is awesome, the full ecosystem around it is amazing, made by such passionate nerds, we are very lucky.

If you have a variation in your genome it may not manifest in a change in your proteome or phenotype. Many variations of a single nucleotide actually don't change the selected amino acid. For example in English we have the spellings mom and mum, one American and one other, and both are understood and mean the same thing. Whereas dog and dug mean something very different. In your specific case the change you have likely makes no difference at all. It could be a chunk that is not read, a chunk which is snipped out, and chunk which has almost no impact on expression, and so on.

Fear of sensory issues is valid and normal. Fear of being treated in a way you don't like by family is both common and difficult to resolve. Talking to your family, specifically your dad, about how this behaviour makes you feel may solve it, but it is also possible it will backfire. Unfortunately there is nothing you can do about how they will behave other than to let them know that it's going to cause you distress.

Speaking to your mother is probably a more effective strategy in this case. Explaining the situation and asked her not to talk to your father yet but to first understand what is happening and why it's a problem for you is probably going to be more effective. If she is able to understand it and explain it back to you in a way that makes sense then she may be able to talk to him in a way that will be more effective given her experience with him. It is worth saying that you value the relationship with him and don't want to cause harm to that relationship as part of the reason why you're speaking to her rather than speaking to him directly.

As for the actual surgery, i've had many surgeries and i have never found the inclusion of metal to be particularly comfortable. I've had it screws put into a burn as well as metal pills which continued to protrude from my flesh after the surgery for multiple weeks. In need the case was it incredibly pleasant, but it was tolerable and the fact that it was time limited made it much more manageable.

The post nasal drip that you've been experiencing probably impacts you every day. If you could have a temporary set of suffering and in exchange have a permanent solution to that problem it is likely worth it if the success rate is high enough. I don't know about the success rate for that particular surgery for your particular condition. That said if there was something that could resolve the issue and had low enough risk i would consider it a worthwhile trade.

The same goes for the sleep., Having a few days of really crappy sleep as a result of anesthesia, post surgical pain, and discomfort from the presence of a splint or similar items is not much to pay for better sleep for the rest of your life. It may suck for a couple of days. But chances are it will become a memory that you won't really experience at the same level as you are experiencing now in anticipation. For me i was worried about open heart surgery and experienced some distress at the idea of the amount of pain it would cause. Now i can remember that it caused pain, however i cannot remember the pain in a sensory way like i could predict the pain. It is much more tolerable after the fact.

Good luck!

Yep, and surviving longer increases cancer rates. Cancer used to be a death sentence, now it is far less so. Many cancers which were a short time from death at diagnosis are now routine to remove or fix. Others that were soon fatal have 5 year survival over 90%, and some are even higher.

We haven't cured cancer just like we haven't cured industrial accidents, but honestly, so few people are eaten by hungry machines and left disfigured that it is likely you know less than a handful. Not cured but reduced to a much more manageable level.

I have well above average vision and my partner has slightly below average. I can see the pixels on a 4k screen at a distance my partner cannot make out pixels on 720p. But both of us find 60Hz, the default for monitors, to be choppy. I think we have reached a fairly good level for pixel density but the refresh rate will keep going up to something like 150-200Hz for displays. Adaptive sync with stable parts being 60Hz and moving parts being higher make sense, as do different refresh rates for different colours. I think eink is also going to play a role as it doesn't flicker except when updating and it looks very similar to paper in terms of detail density.

Honestly, more than a year ago nVidia drivers were absolutely nightmarish. It used to be such a frequent issue that I stopped updates for nVidia drivers until I could take a full system backup. Btrfs has been a game changer, allowing backups to automatically happen on updates and allowing you to boot into a previous state. And given the level of Linux growth through Steam/Valve pushing it nVidia seems to have been trying harder. Only one update issue this year so far and it was a simple roll back, make a change, apply updates again.

For your next hop consider EndeavourOS. It is Arch based and so has pacman and the AUR but it also has sane defaults and good configuration tools. Also, the default is quite pretty. Much less work to get a system going but all the flexibility of a pure Arch install.

The crazy thing is we actually do have things that work in humans but not in mice. Mice are omnivores and are very different in terms of optimal energy state. They tend to run in glucose more easily than on fat and their whole biology is built to be small and fast, with short life spans.

Checking how DNA repair works in an animal which lives for maybe 2 years is great for understanding DNA repair in short lived organisms, but we have tk repair damage for 50 times as long. It is just so much more complex and requires such different tools when you switch from maybe 2 years to maybe 80 years, it really isn't sane to assume it will all carry over.

Now for an accute toxin, say tobacco, sure, some things work just fine. There is not a huge difference between humans and mice when subjected to cyanide or arsenic. Being crushed by a falling piano is going to kill both of us. But a chronic poison? That will take decades to kill? That is very different. We can shed cells in a different way to how they can. We have more mass to store things. We have more energy storage. We have bigger kidneys with more opportunities for filtering. We are different.

When we enter ketosis we have some fairly significant cancer responses. When we maintain fasting for 5+ days we have a fairly large bump in autophagy, a state where the body kills off and recycles damaged cells. This state can cause some types of cancer to be more obvious to our immune systems and allow the tumor to be attacked. In some cases otherwise inoperable tumors can be removed after shrinking them through fasting. This does not replicate in mice. So yes, some treatments (not cures because that doesn't really apply) do work in humans and not in mice.

To be clear though, the two defined states are separated by a voltage gap, so either it is on or off regardless of how on or how off. For example, if the off is 0V and the on is 5V then 4V is neither of those but will be either considered as on. So if it is above thecriticam threshold it is on and therefore represents a 1, otherwise it is a 0.

An analogue computer would be able to use all of the variable voltage range. This means that instead of having a whole bunch of gates working together to represent a number the voltage could be higher or lower. Something that takes 64 bits could be a single voltage. That would mean more processing in the same space and much less actual computation required.

I used spite.

I lived with my partner and two friends who all smoked at the time. We all decided to quit on new years day and by about 2am both of my friendship had started again and by 4am my partner had started too. Pure burning spite and superiority kept me from starting again.

It felt really good to my petty younger self to be haughty and superior, but I was definitely ungracious about it. My partner somehow managed to stay with me through that, they are a very tolerant person, and we ended up getting married and are still together now 19 years later.

My partner also quit about 10 years later using a vape. They outsourced nicotine dosage to me and I was manually mixing their juice, so I reduced it very very slowly. Each time I reduced it the frequency of puffs went up for a while then tapered back to the previous level. It took about a week to level out and about two weeks to use the bottle and I would then adjust again. It took most of a year to slowly land at zero but then it was done and vaping was only done with nicotine free juice and it only lasted a month or two after that. I would strongly encourage it as a less harmful version of smoking and as a reasonable quitting aid.
