  • My number one gripe with organic maps is how fragile the search is. If you don’t write it exactly right, you get no or irrelevant results. Also, it seems to have no clue of what is popular and what people expect when they search for something. I’m not talking about personalized results but for example the following: searching for “Eiffel”, leads me to minor roads, restaurants and all kinds of results unrelated to the Eiffel tower. This is what is troubling me the most.


  • Exactly, this is about compression. Just imagine a full HD image, 1920x1080, with 8 bits of colors for each of the 3 RGB channels. That would lead to 1920x1080x8x3 = 49 766 400 bits, or roughly 50Mb (or roughly 6MB). This is uncompressed. Now imagine a video, at 24 frames per second (typical for movies), that’s almost 1200 Mb/second. For a 1h30 movie, that would be an immense amount of storage, just compute it :)

    To solve this, movies are compressed (encoded). There are two types, lossless (where the information is exact and no quality loss is resulted) and lossy (where quality is degraded). It is common to use lossy compression because it is what leads to the most storage savings. For a given compression algorithms, the less bandwidth you allow the algorithm, the more it has to sacrifice video quality to meet your requirements. And this is what bitrate is referring to.

    Of note: different compression algorithms are more or less effective at storing data within the same file size. AV1 for instance, will allow for significantly higher video quality than h264, at the same file size (or bitrate).










  • The Witcher 3. It’s not far from being 10, but got a very nice graphics update for free and has 2 DLC. The game and the DLC and the free graphics update and a very recent mod kit, all for around 10-15 USD right now on GOG . it’s a steal! I highly recommend it. It became my favorite game of all time, very fast. And it will offer around 100h, and it will also offer replayability. What is there not to like?

  • An equalizer does not have to sum up to any specific number. Each frequency range is basically being amplified or attenuated individually. You are boosting or reducing specific frequency ranges. If you reduce them all equally, then the end result is that your song is lower volume. If you boost them all, your song is louder.

    Of note: boosting songs may cause occasional crackling sounds. If this is the case it is because the boosting is clipping the top end of the amplitude of your signal at various frequencies. So boost moderately. You are better off reducing some frequencies and leaving the rest normal and increase the volume of the source to compensate whenever possible.







  • It’s unfortunate the grapheneos community has a bad reputation, but I think the fact that Daniel stepped down and that the project is very committed and ticking all my personal boxes (and more) really keeps me devoted. I wish there were more options of phones, but I have no issue personally with it requiring google pixels as they have convinced me with what seems like rational and well supported arguments. I do wonder if as someone else mentioned, it may be interesting to have a GOS-light for other phones, just to give them a chance to get into GOS and try it out before getting a dedicated phone. It feels like a high barrier to entry, and a limited version may still be better than anything else available to those people? Just a thought.
