  • Agree with everything you said, but if you’re going to ask me about anything, then the thing I do 40 hours a week every week should be a safe subject. If I’m interviewing a chef, I’ll probably ask them about working in a kitchen. I may even ask them to demonstrate something.

    I think it’s a reasonable expectation.

    The key thing is to be as relaxed as you can be. Interviewing is a skill you learn, so go for a few interviews that you’re not as interested in. Try not to go for your dream job first, because you’ll be stressed to hell. Get a couple under your belt first if you can.

    Interviews aren’t an exam. They’re a conversation.



  • I don’t prepare, because it’s testing a task that I do pretty much everyday. If I can’t do it on-demand I don’t see how I can call myself a programmer. That said, I do have some strategies.

    Often the interviewer isn’t looking for people able to recite detail in the documentation. They are looking at the quality of the code you’ll produce. So I concentrate on explaining my approach to the problem, rather than the code.

    • How am I going to structure it?
    • Where are my concerns?
    • What choices am I making about performance?

    …and so on. If it’s on a whiteboard I’ll often write in pseudo-code that looks something like a language, but I’ll state that I’m not trying to write perfect, compiler ready code.

    I let them guide me to the level of detail they are looking for.

    If it turns out they want to score points on me for missing a bracket, or getting the order of arguments wrong, then I take that as a negative against the company. Interviews go both ways, and you’re looking for people you can work with too. So if they’re going to nitpick in an interview they’re probably going to be horrible to work with day-to-day.






  • Lets start by assuming the balloon stays the same size as it rises in the air column and we’ll ignore the temperature drop. The pressure and density of the gas inside the balloon remains the same, but at some point the air density outside the baloon will drop to match the density of helium inside the baloon. At that point the balloon would stop rising as the weight of the atmosphere it displaces is the same as weight of the helium filled balloon. It’s like a little boat on a sea of air.

    However, balloons don’t stay the same size. As they float up the atmospheric pressure drops. The balloon will expand because the pressure inside the balloon is higher that the pressure outside. It still has a bouyant force on it because the weight of atmosphere it displaces is still larger than it’s own weight, so it continues to go up. Outside pressure continues to drop. Balloon continues to grow. Eventually the balloon bursts.




    1. Until recently any word against Israel was met with the antisemitism hammer. I don’t think they realise how outdated that view is.
    2. Their hands are deep in the cookie jar. They’ve been supplying arms for 50+ years. “You weren’t meant to kill people with them!”
    3. Trump in particular doesn’t really care. All he sees is an opportunity to make money rebuilding Gaza.
    4. U.K. leadership has a real problem standing in opposition to Trump. They’ll insult him in private, but whisper sweet nothings into his ear when in person. They think they’re being clever. They’re not.
