  • A Random Walk Down Wall Street is a great book and one I think every day trader should read. At the heart of it is the Efficient Market Hypothesis, which basically says that asset prices reflect all known information and thus it is impossible for a trader to beat the market over the long term (on a risk-adjusted basis).

    The strongest (and most controversial) form of the hypothesis is that even professional traders cannot consistently beat the market. Even if you don’t agree with that, it seems clear to me that professional traders will always be able to obtain, and analyse, new information before “hobbyist” traders, and therefore by the time a hobbyist trader gets relevant information it will already be priced in.

    That book convinced me that the best way to invest is just to dump money into low-fee, highly diversified ETFs and forget about it. I’m not saying others would necessarily have the same reaction, but at the very least I think an aspiring day trader should read it and be able to justify why they don’t think the points made in the book apply to them.




  • It’s good that they mention the refurbished option. The most eco-friendly phone is the one you have, the second most eco-friendly phone is one someone else is getting rid of. Of course, the repairability promise of phones like the Fairphone is exciting and might make them a good bet longer-term.

    I plan on using my current phone into the ground but I’m not sure what I will do when it finally dies. I think if there is a Fairphone 5 with modern specs by then, I would strongly consider it. I know constant new releases kind of goes against Fairphone’s philosophy so there might not be a 5 for a while, but with the Fairphone 4’s specs I would worry about how long it will remain useful. If there is not an improved Fairphone out by then, I would still consider a Fairphone 4 or would likely buy a refurbished Pixel.






  • While I mostly agree with this, I would point out that mandatory TLS introduces a decent bit of complexity, both in implementing TLS itself (where you should really use one of the established TLS libraries in your language of choice) and in figuring out what to do with certificates (TOFU, etc).

    It’s still a very simple protocol of course, but not quite so simple that you can negotiate a connecting manually over telnet, for example. (Some versions of netcat, on the other hand, do support TLS.)
