  • I don’t know about videos but having a look at the OSI model is a good way to start. It covers the abstract framework for packetizing data including things like the distinction between hardware and software, envelope, encryption, application layer stuff, the whole shebang. The cool thing is by going hardware, network, application you can see where responsibility are and it helps you understand where things can go wrong.

    If you are interested there are plenty of CCNA style courses available on the internet, licit and otherwise, and they go into more depth, and the same applies to RHCE/RHCSA material. The training for certifications like that covers what you want to know but also puts it in context, and again licit and otherwise sources are available.



  • The question is not about what is possible, it is about what is common. Also, I am not saying the SAD is good or even better than vegan. Anyone trying to eat well is likely to make some of the same good choices, such as reducing refined sugars, dropping a portion of their ultra processed foods, and monitoring and meeting their protein needs. Being unable to hit your protein needs on a vegan diet is something an incautious person may experience, but supplementing protein or increasing protein components in your meals is manageable.

    That all said, it takes extra work. Most people don’t have the spare effort to cook at home for every meal, people are time and money poor and stressed beyond all reasonable limits, so we need to try to make some sort of plan that can actually be followed, not just some ideal. Is vegan possible? With effort and education it seems that some people can manage it, so at least some portion of people could do that. On the flip side if someone eats fish and chicken as their meat rather than beef have they not made progress from a bunch of ways? Definitely fewer carbon emissions. I don’t claim to know the answer for what we should do but saying “do this perfect thing” seems counterproductive.


  • If everyone has the same amount of starting capital it is a fair game assuming both can opt out at any time.

    That said, the house appears to not be able to opt out (they definitely can, you just don’t think about that part), and the house has more capital. For them each time someone plays a round there are only 3 possible outcomes. Half are the player loses, then a quarter are the player wins and plays another round, and lastly a quarter are the player wins and ends the game. The only case where the player wins is option 3, in all other cases, so 75%, the house wins because the next round has another chance to make the player lose directly at a 50/50 chance or play another round.


  • I’m reminded of an article talking about an outage at Yahoo! back when they were huge. It turned out the whole outage came down to one person messing up. The manager was asked how they let the person go and they said “Whatever the cost of that outage we just spent it on training, that person will never make that mistake again, nor will they allow someone else to make it”.

    If you have mods trying to manage things and they make a mistake you don’t axe them, you discuss the situation and work in good policy for going forward. This one case is costly to the community, but nowhere near as costly as losing someone with this experience.

    As for the vegan diet for cats issue, in general people who do vegan diets for kids and animals run a high risk of causing harm. Is it possible to do correctly? Maybe. Is it likely that an individual who is not trained in that field will manage it? No. But should it be investigated? Sure, but o my with experiments that actually do teach us something, no wasted studies of 3 weeks on a diet and checking blood tests, or comparing vegan kibble to omnivore kibble. Still, the same issues plague human dietetics and we don’t have the answers there either, so yeah, maybe we should all chill a little and work together rather than identifying with one side of the argument and vilifying the other.


  • OK, so good, a clear starting point.

    First, adding muscle is a fantastic way to go. Muscle burns energy and new muscle is not insulin resistant, so it lowers your overall insulin resistance. This is key to liberating fat and burning it for energy.

    The other big key is diet. Your current diet is overwhelming your body’s ability to burn without storing as fat. This means you are gaining body fat and this will get worse over time. Gaining muscle can help a fair bit but your existing muscle tissue along with other things like fat cells and other organs are all at the point of damage from high sugar levels in your diet. The fact that you can make yourself go to the gym is great, it means you have caught this before it has gotten too bad.

    So to make progress on your diet you probably need to do a couple of things. First is check for other symptoms like swelling around the jawline, fat build up over the spine between your shoulders, rash and skin discolouration, pale gums and lips, and any sort of weakness in nails and hair. These are all potential indicators of an acute deficiency and may need medical support. That said, all of these are generally helped by dietary work, so if nothing massive is presenting like a goiter or anaemic gums you should probably just move forward with diet and reevaluate later.

    So what to eat. The biggest problem seems to be sugar, followed by the sugar/fat/salt hyper palatable mix, then hyper processed, and lastly problematic plants. If you eat meat, which I would strongly recommend, then paring everything down to very simple meals is the best option. A kilogram of meat per day is a reasonable base for basically everyone. If you start there and can make it a week without anything else you will have a good starting point for completing an exclusion diet. If you can’t jump directly to that then dropping out the worst items is a good step.

    Dropping the worst means getting rid of the most packaged and insane foods, like cakes that last 6 months on the shelf or items with ingredients lists longer than The Art of War. If you keep eating sugars but they are in simple forms, for example honey or while fruit, you will avoid most of the worst stuff. It would also be good to learn more about cooking meat properly, so learn how to fry steak, cook chicken wings, and maybe roast a leg of pork. Learn to make basic stuff that tastes good and you will find reducing other crap easier.

    Ultimately trying to hit numbers of grams of fat, protein, and carbs is a losing game. You don’t know all the internal systems you have and how they allocate energy, but you do have a handy system they operate with, hunger. We should fix your hunger to make it work properly and that is what the above is for. You have simple foods, your body learns what they provide, your hunger becomes more accurate for what you need.

    Once your hunger works properly you will do something like work out and you will feel more hungry in the day or two following it. Then chasing numbers won’t be needed at all and you can relax.


  • You’ll get a lot of contradictory answers with this question because of two major issues.

    1. There is more than one way to make your scale number go down.

    2. Your scale number going down can be for multiple reasons.

    For example, dropping a bunch of body fat is a way of posing weight, but it does not look any different on the scale than losing muscle mass or losing a leg. You can have more healthy recomposition where you drop a bunch of fat slowly over time and gain some muscle but overall lose absolutely no weight on the scale, and you can also gain weight without changing fat but be in a better position.

    So what would you aim for? It depends on your goals. Do you want to be jacked? Maybe you have early signs of type 2 diabetes and want to stop it there. Or maybe you just really want to get rid of your skin issues like acne and dermititis.

    Nobody benefits from being insulin resistant. That is the state that pushes you towards weight gain, diabetes, heart disease, and many other issues including dementia. Fixing that is a central goal for a lot of people and it actually helps with most other health related goals. If I were starting somewhere that is where I would probably try to start.

    That said, if you have very little muscle that may be better to work on.

    Can you give more detail about your goals?


  • First, start big. Get the basic shapes right with large lettering. Ideally you would have something you are comparing to like a stencil or grey printout so you can see the difference between your writing and the target.

    After you have the shape fairly good large you can shrink it down. You can take your time getting to that and just make a little progress at a time.

    If you find it impossible to shed your current handwriting consider using grid paper to force spacing and maybe try your non-dominant hand.


  • My understanding is you make fewer but more replicable mistakes. If you use a wire you have to trace it, keep the length consistent for timing reasons, use very consistent soldering technique, and ultimately you have a hard time tracing issues. With a homemade PCB you generally do get what you ask for in terms of circuitry. Traces are the right length, right thickness, right spacing, and if not then the whole board is similarly impacted, so it is obviously broken or not broken. If you mess up your design then you have a problem, but if you did the process right and you have a valid design then it works.

    That all said, homemade PCB is a large time sink and modern PCB manufacture is so cheap and fast it doesn’t make sense to do at home for the most part. You can literally get a complex board faster by ordering it from halfway around the world and having it posted than making it yourself. I would say it is a good learning exercise, not a good manufacturing or prototyping practice.



  • Working for a VoIP company in the early 2010s I rm -rf’d the /bin/ directory. As root. On a production server. On site.

    I ended up booting from my phone (android app for iso booting) then manually coppied over the files from another machine. Chrooted and some stuff was broken but rebuilding from the package manager reinstalled everything that was missing. Got the system back up in around 40 mins after that colossal screw up. Good fun and a great learning experience. Honestly, my manager should not have had me doing anything on a root shell with no training.


  • UBI will cycle in the bottom of the economy.

    When you give a rich person more money they buy assets and increase their wealth, it does not impact their spending activity and has no measurable impact on economic activity.

    When you give a middle income person more money they buy something new or pay down debts. Buying something new stimulates economic activity, but paying down debts is really just another wealth transfer to the banks which are owned by rich people.

    When you give money to low income people they spend it. They have unmet needs and always have something they can spend that money on. That money then generates economic activity.

    Increasing economic activity is what all of the interest rate and inflation talk is about. If you get people spending money that generates activity which increases wages, increases income, and decreases wealth inequality.

    A good example is during the GFC the Australian government gave low income people $750AUD, about $350USD. The prime minister asked people to spend this money rather than save it. People bought a bunch of things, in the people I knew it was mostly TVs and new clothes, things you can put off for ages but benefit from whenever you buy them. All of this purchasing stimulated the economy, leading to Australia being less impacted than almost any other G7 nation. We recovered very quickly and boomed from there.

    If you want a more long term example look at any welfare. If you have extremely poor people they just die. They are underfed, have weak immune systems, and they face imminent death. They can’t access housing so they end up on the street. They have tonnes of inteactions with police and end up in the criminal justice system. They end up having their lives ruined and being purely a drain economically. They suffer.

    If you give them enough money to have housing and food they are not going to be as costly to manage. They won’t require policing, they won’t get sick as often, and they will suffer less. Will this increase the competition for the lowest cost housing? Yes, but the answer to that is to build more housing. Even with the impact to housing cost this will not result in 100% of that payment going to landlords. People don’t pay their whole income for rent, they will buy food and other needs first, so if they are faced with too high a rent cost they will remain unhoused but at least tbey will eat.


  • I have some experience with mental health in Australia and it is pretty dire honestly. There is a constant sense that the staff are concerned first with making sure you don’t hurt yourself because that would be a breach of their duty of care. This unfortunaty made much of the interaction between staff and patients adversarial.

    I am currently entering the individual suppory industry and we have a concept called dignity of risk. You have to remember that people are entitled to take risks that they consider worthwhile regardless of what you think. This means if someone wants to smoke weed that is their choice, I can’t stop them. If they want to drink that is their choice and I have to respect that. This is because they are their own people and have their own autonomy.


  • Yes, it is possible, though fairly prohibitive. You can get modules for connecting a Sim card to your laptop to make and receive calls and SMS, so all the third party authentication messages and calls can be done. Apps can often be run through an emulation layer for Android, not so much for iOS, but yeah, it can mostly be done.

    That said, there are devices like the Pinephone which run a mainline Linux distribution like Arch or Alpine and can also do calls, SMS, and if you are brave use some android apps. If you can use a Pinephone for it then you can use another Linux laptop with a phone module to handle everything else.

    I am much more worried about things like banking now. A bank that allows use of an app on your phone with NFC is great but when they take away using anything else I would become a little more worried. If they can keep an option open, say having standard cards along side phone NFC, then the lock in is much less profound. If we get to a point where they cannot operate without Google or Apple giving the go ahead then they cannot move away if things get bad, so those monopolistic companies can extract more value from those banks and that gets passed down. This applies to tonnes of other services like taxis, food delivery, booking doctors appointments, and so on.


  • Option 1, the vast majority of STI transmission is between m/f sexual partners.

    Option 2, plenty of m/f couples have anal sex so it is either immoral for both or for neither.

    Option 3, not all gay couples have anal sex, plenty just do oral and some don’t even have sex, plenty of ace people out there.

    Option 4, condoms work well and really do prevent the spread of STIs.

    Option 5, what about lesbian sex? They are also homosexual but don’t have penises, so is anal sex not an option for them?

    Option 6, what right do we have to judge other people’s sexual preferences and activities? You are allowed to drink, smoke, and eat unhealthy foods, not to mention people refusing the vaccines for covid and influenza, so even with things that kill a lot of people every year we let you do it, so what makes anal sex for men different?

    Option 7, what about pegging? Can anal in an m/f relationship involve penetration of the male? Is that the same or different to the gay men situation?

    And lastly, option 8, if they get to say gay anal sex is immoral then what stops gay men from saying exercising power over a community based on unsupported claims is immoral? If their specific religion is correct then all others must be someone scamming or lying, so that must be immoral, right? If not, how and why?



  • For the software side I would recommend Linux Mint as a great simple starter distro with good support and a nice community. The overall design paradigm is about maintaining familiarity while also making sane defaults and simplifying processes. Because it is Ubuntu based it is also easy to get documentation and support because what works for Ubuntu also works for Mint.

    For hardware it really depends on your budget and locality as well as use case. Laptops vary much more country to country than you may think, so it may be worth thinking about what is local to you. For example, I live in Australia so System76 is a bad choice here, same with SlimBook (I think that is the name, European KDE laptop that advertises with that French(?) YouTuber, they don’t ship here.

    Also, when looking at laptops the RAM configuration is important. If you have two RAM slots but only one RAM stick you will have really slow memory access. This will bottleneck for both the CPU and GPU if you are using both at the same time, say during gaming or doing AI work. Swapping out the single stick for a matching pair or just adding one more stick that matches what it already has will let both ports work together, making everything faster. Also when I say matching I mean in terms of size and speed. If you put 3200MHz and 2400MHz in the system at the same time the 3200MHz won’t just down tune to match, they will both go slower as far as I am aware. Best to match not only the speed but if possible the brand and ideally model, there are lots of little differences between RAM sticks and honestly it has never been worth the trouble in my experience to have mismatched sticks, I just replace with a matching pair.


  • Before the more modern definition took hold propaganda was not a term that held any real negative connotations. It was really just like marketing or evangelising, a behavior or product which uses various methods to change opinions. The big problem is when you have political or corporate powers using these tools to change opinion about something in a way that degrades democracy or causes harm.

    For example, oil companies stand to benefit from people being uncertain about the science, so when they engage in propaganda they are trying to inject doubt where there is none and to do so in a way that will benefit them in the short term. This will cause massive harm in the future, potentially leading to a significant number of wars and a staggerig death toll, but that is not part of their consideration.

    Another example is alt med. When someone claims that their pill can make your brain work better and will also boost your sexual performance all while protecting you from the dangers they just told you about they obviously stand to benefit from you believing them. They create the need and then offer the solution. Alex Jones is a good example of this. He tells you that the global elite are planning nuclear war, then in the next ad break tells you about iodine for radiation exposure.

    So why is propaganda frowned on? It is more like propaganda is the label we give to marketing or evangelising that we consider worthy of frowning. Someone in another countries may sort different things into evangelising, marketing, and propaganda categories but they will do so based on their understanding of the world and you will likely agree with most of their sorting. Almost everyone thinks that Nazis are bad and put their marketing in the propaganda bucket.


  • It looks like it is downsampling the video or streaming after converting to another codec. Some codecs are fine for decoding on the server but the app may not support them so the server converts them. Some files are of higher quality than what the server is configured to deliver so it downsamples to stream it.

    Check the configuration and look for anything to do with codecs, hardware decoding, streaming quality, and so on. It may also be on the app, so if you can access a different interface then test that to narrow down the issue.


  • Something I have found is missing from both of these suggestions as well as every podcast app on device is transcoding to speed up so it is not sped up on the fly. For a lot of phones and other devices the task of playing back at 2x speed is enough to demand a higher power state than what is required to play a sped up file. For efficiency doing a single pass of speeding up the audio then playing back at that speed would use less power during the playback phase, allowing you to download and speed up all of your podcasts at home while on charge then listen for long periods without completely killing the battery. I have checked with a few if the open source devs and this is not a feature they see utility for so nobody intends to make it.
