  • Quickly checked out Keras. Installed and played with it for one day, running tutorial basic tutorial stuff. So I know how to quickly start using it, if any projects that would benefit it pop-up.
  • I'm currently arranging networking for a real estate limited company. It's interesting to see how much prices drop from public list prices when there's some volume behind the order. On the other hand this just shows how ridiculously expensive many 'corporate Internet' connections are. It's funny that individual home Internet connection costs N units, but if you're buying it for dozens or hundreds of individuals price is N / X much lower anyway. And if you're buying it for company or corporation the price is suddenly N * X. Even if we're talking about same type of Internet connection and capacity. Ok, it has been obviously clear that Internet connection pricing is totally political and has nothing to do with the real costs. No wonder many small businesses order just 'home' Internet connection and then forward the invoice to company, because that's lot cheaper. Often even unlimited 4G data will do, because in many cases that's faster and cheaper than VDSL2, Ethernet or fiber technology. Yet you have to know the regionally available actual 4G performance as well as know the hours when it's bad, if it isn't all the time.
  • Embedded devices and web servers. Sometimes I just wonder, how it's possible that they make so slow stuff. Basic requests taking tens of seconds or even minutes. No wonder those are really easy denial of service attack targets, because just a request per second clearly exhausts system resources. Absolute $hit code is just around everywhere. If there's so much code which doesn't work or does perform absolutely ridiculously bad. What kind of security you're expecting? I would say none, none at all. Because even the 'more important' stuff from selling aspect is that seriously broken. Btw. I've written all this, while waiting for one HTTP request from LAN to return. Sigh.
  • Two awesome articles by The Economist.
     - The world’s most valuable resource is no longer oil, but data
     - Data is giving rise to a new economy
    Very nice articles indeed. Data and more data, what else could I say? Yet there's absolutely staggering amounts of detailed data, which isn't being utilized, processed and analyzed at all. I guess this is something what I've mentioned dozens of times.
  • Predix is a software platform for Industrial Internet aka industry 4.0. For information trade see Infonomics. kw: Interoperability, Information transparency, Technical assistance, Decentralized decisions. Principles of Infonomics is worth of reading. And I do agree, that information is radically underutilized in many organizations. We do have all this information, but we're not using it for anything.- Hah, same conclusion again as on previous bullet point.
  • TED: The future we're building - By Elon Musk.
  • ITU-T G.984 Gigabit-capable Passive Optical Networks (GPON) - Encountered term which I couldn't recall. I did read lots of all kind of documentation but this was first one for a long time I really had to read more about.
  • One integration project, where there are the usual issues: Communication, disinformation, undocumented changes, not understanding of logs, changing data structures over and over again and so on. All the usual stuff. Also people misread logs or don't have logs at all and they clearly don't know how their stuff works, and then they complain about things being broken which actually aren't. Things are working exactly as they've requested, but they don't remember anymore what they've requested. Thank you for that, integration projects as usual.
  • Studied customs and excise duty taxation legalization in Finland. It's in own art, but luckily I don't usually have to deal with that. And it's not that complex after all, after you understand the basic concepts and principles. It's just like anything else, first it seems strange and messy, but there are of course exceptions but most of it follow pretty clear rules. It's just like any RFC.
  • Some things in Duplicati 2 documentation are very annoying. First of all, documentation isn't very accessible. Secondarily, the default values for many parameters aren't mentioned. So it's hard to know if some parameter should be used to override a default value, when the default isn't known. Reading the source code helped again. Default compact threshold seems to be 25%. I hope they've updated the documentation since.
  • Net neutrality? Hmm. My Internet connection contract already says that they reserve right to: Queue, Prioritize and Throttle traffic. This is used to optimize traffic. - Doesn't sound too neutral to me? It's also clearly stated that some traffic on the network get absolute priority over secondary classes. - Interestingly at one point 100 Mbit/s symmetric connection wasn't nearly fast enough to play almost any content (even 240p) from YouTube. - Maybe there's some kind of relation, maybe not.
