  • Because they mean very different things. Imagine you tallied the spending of 5 people in your restaurant:

    10 15 30 100 150

    First of all that distribution has no mode, so let’s then check the next 2 customers.

    10 15 20 30 100 150 150

    Cool, now checked with 7 people this, and we can say the following.

    The mode is to spend 150. Almost no one does this, but that is the mode regardless.

    The median is 30, this tells you that half the people spend more than this, and half the people spend less than it. However it doesn’t give you an accurate idea, because the people who spend less spend close to it, but the people who spend more spend way more. So if a guy spends 35 he would look like a high spender, but in fact he probably should be in the low spending category.

    The average is 67.85, no one spent this amount, but this tells you that if a person spends more than that he’s a high spender, so of someone came in and spent 35 you would know he’s not one of your high spending customers.

    Now let’s see how each of those numbers is at predicting how much 7 customers would spend, let’s look at the same values, where the customers spent 475. The mode tells you that people will spend 1050, that’s absolutely wrong. The median tells you that they’ll spend 210, that’s also very wrong. The average however tells you that they’ll spend 475 which is the exact number.

    This is the same for every other statistics, even if it doesn’t make any sense to say that people have an average of 2.3 kids, if you were planning on receiving 10 random families they would probably have 23 kids in total. Average is good at predicting large groups, and that’s the information we usually care about when we’re trying to express a large group in a single number. If you want a second number the obvious choice is the standard deviation, in the example above the standard deviation is 63.76 this gives you an idea on how accurate is your average at predicting, so in the case above not very accurate at all, but if we imagine that the number of kids above had a standard deviation of 0.2 you can be 68% certain that the 10 families will have between 21-25 kids, or 95% certain that they will have between 19-27 kids, or 99.7% certain that they will have between 17-29 kids. Working with the level of confidence in a prediction allows you to evaluate certainty at doing things. If you only knew that the median was 2 kids or that the mode was 1 kid you couldn’t predict things with any accuracy.


  • First you need to understand the difference between a dominant and a recessive gene. Dominant genes manifest if they’re present, recessive genes manifest only if there are no dominant genes present. A quick example is blood types, 0 is recessive, both A and B are dominant, you have two genes that specify your blood type, if both of them are 0 you are type 0, any other combination with 0 you’re not 0, i.e. 0A or A0 are A, while 0B or B0 are B. This means that a person with blood AB can’t have a son with blood 0, because his son will either have one A or one B inherited from that person.

    Genetic diseases that happen because dominant genes are hard to miss, if you have the gene you have the disease, however genetic diseases that need recessive genes can be carried for generations without anyone manifesting symptoms. But of two persons have the same recessive gene it’s quite possible that their children will have both of the genes be that one and manifest the illness. The chances of two random people having the same recessive genes are quite slim, but the closer people are genetically the higher the chances that they have the same recessive genes. Using blood type as an example, if a parent is AB and the other is B0 their children have 0% chance of being 00, but they have a 25% chance of being A0 and 25% chance of being B0 (the other 25% being AB and BB). Now if their children A0 and B0 have a child of their own that child has a 25% chance of being born 00, whereas if any of them had a kid with a AB, AA or BB the chances would be 0%.



  • I get you, I don’t like going to the office, I hate small talk, I feel I’m not productive because people keep talking, too. That being said the proper response is to answer the pleasantries greet people and be nice, afterwards you put your headphones and work, even if you’re not listening to music a good ANC headphone is a good investment, and people will only try to talk to you for important things, because they won’t poke someone to ask them about their day or other similar stuff.





  • I don’t think so, I mentioned this scenario in another answer, imagine they took the pills to the patient at 7, the patient only took them at 10, but the chart says he took it at 7. The next day the doctor looks at his chart and decides enough time has passed and a surgical procedure can be done to the patient. Because he took it at 10 that’s not true and because he’s on blood thinners there are complications and the patient dies. Who’s legally at fault? The doctor has a paper trail to explain why he did what he did, this leaves the blame entirely in the hands of the person who signed a paper saying the patient took the pills at 7.


  • It doesn’t, you take the pills to the person, if they don’t take them immediately ask them to take the pills now, if their answer is a refusal chart it and leave, if their answer is something like “I’ll take them later”, explain that you need them to take it now, if they still refuse chart it and leave (with the pills obviously), possibly come back later, you have other patients to take care of and can’t waste time on a staring contest. But if you give pills to someone, put it in the chart that they’ve taken them at X time but they actually took it 3 hours later, doctors might act on that chart and cause problems to the patient and hospital. E.g. if the patient will have some surgery the next day the time they took their blood thinners is extremely relevant, the patient can’t be expected to know this, you as a nurse might know, the doctor who will read the chart and decide on the procedure knows but might be acting on wrong information if you didn’t watched the patient take the medicine. If the next day the doctor sees a refusal to take the medicine at the appropriate time he might choose to alter or stop the procedure, explain to the person why he’ll have to stay another day at the hospital and that this time he better take the pills at the appropriate time or he’ll have to stay another day, and not risk putting someone’s life in danger because a nurse decided to write a random time for when the patient took the pills. Think about it this way, if you wrote that the patient took the medicine at 7 but he actually took it at 10, and he died or had complications because he was still on blood thinners during surgery, who do you think will be to blame? The patient who was not told the medicine had a specific time? The doctor who has a paper signed by you that the medicine was given at 7? Nope, 100% the nurse who wrote the wrong time on the chart will be solely liable for this.

    When I read the question I thought it’s stupid, he’s an adult, but the more I think about it the more it makes sense that nurses should chart only when they’re sure.


  • The easiest options in order of effectiveness, and how to bypass them:

    1. Do nothing.
    2. Reset Windows or erase all files you don’t want to be found. To recover from this you need a specialised piece of software that will recover the files, but not the names or locations, so while the actual data is easily recoverable, the person would need to sieve through most files you’ve had in your PC since forever with no order.
    3. Zero the disk, my way to do this would be to boot a Linux USB and run for example dd if=/dev/zero of=/dev/sda, this will delete EVERYTHING on that disk, including windows, partition table and the bootloader. The way to recover from this involves specific hardware and a sterile lab, unless the authorities are investigating you it’s very unlikely someone will recover from this.
    4. Multiple passes with zeroes and random data, the way I would do this is the same as above but use /dev/urandom for the if parameter, run it multiple times, then run once with zeroes. Theoretically it could be possible for the same lab as before to recover some data if the machine ran out of entropy and didn’t wrote actual random data, and someone could predict the random data and compensate for it on the residual magnetic field, but it’s highly unlikely. Almost no one would be able to recover this, and if someone can they will charge A LOT.
    5. Physical destruction, e.g. drill a hole or smash the disk for an HDD, break the chips for an SSD.

    All of that being said, why throw it away? Why not sell it or use it to self-host something cool like a media centre or a steam machine if the laptop is good enough.



  • You can be Latin and live your life as if you weren’t, one thing does not contradict the other, just like you’re Mexican and that doesn’t necessarily tell me anything about you or how you live your life. In fact Mexican is a subset of Latin, so if you are Mexican you are by definition Latin. But like I said, there is no such thing as neutral when we’re talking about culture, what you think is neutral will sound strange to other people.


  • I’m not saying you sound angry at me, you sound angry at your own heritage. Latina is the female of Latino, you said you’re not a son, so the assumption is that you’re a daughter. Yes, there’s nothing biological, there’s also nothing biological in being a Mexican or an Argentinian, but regardless of how you feel about it you’re still a Mexican and I’m still an Argentinian, nothing racist about that. You might not identify ad Mexican, but you are, and others will identify you as such, there’s nothing wrong nor right with being a certain nationality or culture, you are Mexican and you are Latino, you don’t have to be a stereotype of either, nor do you need to agree with what others Mexicans or Latinos think about anything.

    You keep saying you like to stay neutral, but you grew up in Mexico from what you told, so your neutral is different from mine, and it’s different from an Irish or Italian. Culture is in everything, a food that you might consider weird is someone else’s favourite breakfast, e.g. toast with beans in the UK, and where you grew up informs a lot of what you consider neutral.


  • You can identify as whatever you want, you will still be a Latina though. Nope, I’m not Irish, nor do I wish to identify as such. Don’t mean to offend you, but you read like an angry teenager that’s angry at their parents or has watched one too many racist movies depicting Latinos as a bad thing, in time and with age you learn to appreciate your origins, and the more people and cultures you know the more you realise you do have a culture and that your culture is different from others. Getting to know other cultures and appreciate their differences is one of the cool things in life, understanding that what you consider normal is for others strange and vice-versa can be an eye opener.


  • You were born in a Latin America country, presumably son of Latin Americans, you grew up in said country, you are a Latin American, or Latino for short.

    People born in USA with USA born parents that grew up in the USA are Americans, the ones that claim to be Italian or Irish are made fun of by a actual Italian and Irish people, source I’ve lived in Italy and now live in Ireland.

    Latin America is arguably one of the largest demographics in the world, since it covers essentially all of the countries in the American continent with the notable exceptions of USA and Canada. An Argentinian like me will have almost nothing in common with a Mexican like you (except perhaps we both watched el chavo del 8), or at least no more than I would have with a Canadian, yer we’re both “Latinos”. Plus I don’t see what’s the problem with being a Latino, that doesn’t mean anything, whatever prejudice someone will have for you being Latino, they will have it regardless of whether you consider yourself Latino.


  • Not using bitcoin and its ilk is big to (in absolute terms its only so big but for what it does its a massive cost in energy).

    I mean, yes, and no, Bitcoin actually produces less CO2 than the alternative, it’s just that people won’t ever stop using the alternative so all of that CO2 will continue being created. People have this wrong idea that Bitcoin replaces credit cards, when in fact what it replaces is money. And Money is a CO2 hell, it’s made of cotton, so you need to add the CO2 cost of producing, transporting and processing the cotton, add the cost of manufacturing the inks, printing the actual money, transporting it again, then all of the CO2 cost in keeping that safe, moving it from one place to another, etc, etc, etc… Yes, Bitcoin and the like consume a lot of electricity, but most server farms are in zones where electricity is very cheap, and that usually means green energy (hydroelectric, wind and solar plants produce a lot of surplus energy, so they sell it very cheap, which is why you’ll see most server farms for Bitcoin are located near such plants), but Bitcoin could process Visa level amount of transactions with that same amount of energy, i.e. it doesn’t need a certain amount of energy to process a single payment it needs a certain amount of energy to process a block of transactions, regardless of block size, which means that theoretically Bitcoin could replace all of the money in the world using the same amount of electricity it’s using now. And the hardware for the server farms could theoretically be old GPUs that would otherwise become e-waste.

    Having said that there are technical limitations and a long debate on how to better scale Bitcoin, and old cards will never be as profitable as new ones so it’s unlikely that old cards would get used for mining, but they could if Bitcoin (or others) were designed around that idea. At the end of the day my point is that most people don’t consider the scale of what Bitcoin is replacing.
