  • Secure Administration Processes. When using default and shared credentials is forbidden. It seems that people are just as smart as you would expect. If rules say you must not use passwords like: default or password. When you run checks on what kind of passwords are being used, you'll find up that people are setting up passwords like default1 and password1 which aren't on the forbidden passwords list. - Thank you for that, smart engineers. Often it feels that people are using all their ingenuity to be stupid. Of course that's one way to do it. Instead of trying to do things smartly, you're spending considerable effort to think how to implement something that it's implemented according requirements, but in the most stupid possible way. - Next time someone complains that their disk is full, I just format it. Job done, now there's plenty of free disk space. - Be careful, what you ask for. - Remember to make your requests idiot proof. - But I can warn you, it's surprisingly hard.
  • Using IoT devices to plant fabricated planted evidence. - Interesting discussion with many example cases. Which I'm not going to elaborate about.
  • Getting sick'n'tired about people who just don't get how SMTP works. Yes, everything needs to be right.
  • Enjoyed Windows Task Scheduler unreliability issues once again. Run on system start up, simply doesn't work. But I assume this isn't any kind of news to anyone. Work-a-round? Make the script run every 5 minutes, and make it hang at the end and set script not to rerun if it's already running. Works, but doesn't make any sense whatsoever. Just pause / sleep for ever at end of script. Also the fact that the workaround works perfectly, just makes it 100% obvious it's MS fail. Just can't stop loving things which doesn't work as supposed and then you've have to create some strange workarounds.
  • More elite engineering: Google+ says that the website doesn't work because I'm using Chrome Browser on Android. It's wonderful how they can do stuff like this. It seems they clearly need more top engineers, so they can fail even on the level of simplest things. Google's own Google Plus and then they do not support a Web Browser by Google on Google Platform (Android). I wonder what they'll be supporting? Maybe latest Edge or Windows Mobile? - Exact quote: "Your browser is not supported by Google+ You may have an outdated browser version or an unsupported browser type."
  • I've designed full immersible 3D web site. Which is the coolest site ever on this planet. But because you're not using SL-WebBrowser-B201 build G9 on SL-B82-Operating-System-C4.322, you're just unable to see it. But it's your loss. My stuff is so cool, you wouldn't get it anyway.
  • Latest tech. Just created extremely traditional integration for one project using RS-232C 9600,n,8,1 and CSV data over it. Neat. Btw. This works extremely reliably. No need for über tech. ;) The most unreliable part of this is the USB RS-232C adapter, which unfortunately aren't very reliable. Those got hardware and software issues, etc. Even if we try to use high quality ones.
  • Quote: 'The government also has the power to force companies to “maintain technical capabilities” that allow data collection through hacking and interception, and requires companies to remove “electronic protection” from data. ' - Isn't that totally expected? Of course it is. It would be strange to assume something else.
  • Radar vs WLAN (WiFi). Some 5 GHz WLAN articles mention that RADAR use power levels like 60 W compared to WiFi 100mW power. But I just checked their info page about local weather radar, and it's not 60 W. It's 250 kW pulse power and 0.005 with duty cycle. It's still 1250 W when converted to continuous power. If I got that right. But without further analysis and information, it's hard to say, how badly short strong pulses will disturb networking. When serving in military, local military radars often caused repeated disturbance on radio, due to high power which would totally overwhelm the receiver. Even if it's operating totally different frequency.
  • Python 3.6.0 hashlib also includes scrypt. Awesome. Also Shake and SHA-3 are included.
  • Switching cost (switching barriers) is something which is being often considered when changing service providers. Yet, unless the old service provider isn't bad enough, it makes change to keep using the old service provider and just using new provider for new contracts.
  • Something different: Gaia (spacecraft / space telescope) and Alenia Aermacchi M-346 Master
