The first thing we had to do with the sample was to extract the DNA present in the water in a pure form for the PCR.
As you would expect, this consists of a purification procedure with several steps.
In each step we take a physical or chemical action on the sample, which splits it into two parts: the one with the DNA and the one without.
We then take the part with the DNA, and throw away the one without the DNA.
The first steps are coarser, and finer and finer splits are done as we move forward.
In degrees Celsius:
  • 25+
    • palm tree shade and coconut water. Seriously though, if there's some shade or earlier morning/later afternoon it's OK, but if it's on an open road at midday, be careful, and stop early if you start getting slightly dizzy, it only gets worse!

  • always upvote questions you care about, to increase the probability that they will get answered
  • never upvote other people's answers unless you might gain from it somehow, otherwise you are just giving other high reputation users more reputation relative to you
  • only mark something to close or as a duplicate if it will bring you some advantage, because closing things creates enemies, especially if the OP has a high profile
    One example advantage is if you have already answered the question (and the duplicate as well in case of duplicates), because this will prevent competitors from adding new better answers to overtake you.
  • protect questions you've answered whenever someone with less than 10 reputation answers it with a bad answer, to prevent other good contributors from coming along and beating you
  • when you find a duplicate pool answer every question with similar answers.
    Alter each answer slightly to avoid the idiotic duplicate answer detector.
    If one of the question closes, it is not too bad, as it continues netting you to upvotes, and prevents new answers from coming in.
  • follow on Twitter/RSS someone who comments on the top features of new software releases. E.g. for Git, follow GitHub on Twitter, C++ on Reddit. Then run back to any question which has a new answer.
  • always upvote the question when you answer it:
    • the more upvotes, more likely people are to click it.
    • the OP is more likely to see your answer and feel good and upvote you
  • if a niche question only has few answers and you come with a good one, upvote the existing ones by other high profile users.
    This may lead to them upvoting or liking you.
    Even if they don't, other people will still see your answer anyway, and this will lead to people to upvoting you more just to make your great answer surpass the current ones, especially if the accepted one has less upvotes than yours. Being second is often an asset.
  • always upvote comments that favor you:
    • "I like this answer!" on your answers
    • "also look at that question" when you have answered that question
  • don't invest a lot in edits. They don't give you rep, and they can get reverted and waste your time.
    Why are you trying to help other people's answers to get rep anyways? Just make a separate answer instead! :-)
  • if you answer a question by newbie without 15 reputation, find their other questions if any and upvote them, so that the OP can upvote your answer in addition to just accepting
  • If you haven't answered a question, link to related questions you've answered on question comments, so more people will come to your answers.
    If you have answered the question, only link to other questions at the bottom of your answer, so that people won't go away before they reach your answer, and so as to strengthen your answer.
  • if a question has 50 million answers and you answer it (often due to a new feature), make a comment on the question pointing to your answer
  • if you get a downvote, always leave a comment asking why. It is not because you care about their useless opinion, but because other readers might see the comment, feel sorry for you, and upvote.
  • ask any questions under a separate anonymous accounts. Because:
    • intelligent people are born knowing, and don't ever ask any questions, so that would hurt your reputation
    • downvoting questions does not take 1 reputation away from the downvoter, and so it greatly opens the door for your opponents to downvote you without any cost.
Black EUR 44, 1 smaller than normal size as recommended by website.
Bought SM-SH56 cleat to accompany.
When it arrived, it felt a bit too long, around 2cm maybe free space after toe, and when I walk and the front part touches ground, heel comes off a bit, which is annoying. But I was too lazy to give it back and take the risk of a second try, also it felt correctly tight on sides. During first test ride it felt good.
It is slightly water proof. But if it rains a lot, it will get soaking wet. And once it does get wet, it feels like it is very very hard to dry, there don't seem to be any holes underneath.

Thali Updated 2025-07-16
Indian vegetarian thali is the best thing ever! The Southern version in particular. Also do watch a video on how to eat it.
A good place to have it abroad is Saravana Bhavan. The founder killed a dude to marry his wife, but failed and was sentenced to life prison. But he died in 2019 so we're all fine eating there now.
Figure 1. Source. This Wikipedia image of Thali is fundamentally wrong: you have to have a banana leaf on the bottom of the tray!
Oxford mathematics Moodle Updated 2025-07-16
Has a mixture of open access and closed access. But at least it can have open access unlike the in-house systems such as Canvas where everything is necessarily paywalled!
Sometimes things appear open but don't show any meaningful content if you are not logged in, which is annoying.
But at least it gives a clear public course list, thing that certain departments (cough Department of Physics of the University of Oxford cough).
The organization is a bit crap, when you expand e.g. C Michaelmas term it shows nothing, just a search.
The way to go is via the year year categories e.g. "Year 2022-23": courses.maths.ox.ac.uk/course/index.php?categoryid=734. Term splitting is annoying, but one can stand it.
There seems to be no way to list all versions of a single course across multiple years besides just doing a search e.g.
