- I've spent last months, doing tons of SAP integration work daily. It's just amazing how much work 'simple' ERP integration can take. Amount of details is overwhelming. And every minute detail needs to be agreed, specified, documented, coded, tested, approved, and so on. Well. Only good thing is that I've got 100% confidence that the job will get done, and the system will work well in production. Been there done that. But it just sucks fun out of hobby programming, if you do it too much of coding at work.
- 5G @ Wikipedia - article fully read, good stuff.
- Had a long discussion about networks with networking gurus. Final summary was, IPv6 is not necessary, it got no use after all. Also why would anyone need a public IPv4, because CGN works perfectly. There's no reason to have even a public dynamic IPv4 address.
- The statement above reminds me about 64 bit computers. Why would anyone need one? 32 bit systems works just well. I guess we're going to see pretty similar transition at one point. After that, nobody's asking for IPv4 anymore, except for real legacy use.
- Lots of configuration work on several servers. Sometimes it's just oh well, when you learn something new. I didn't know about timesyncd. It seems that so much documentation refers to ntpclient or ntpdate. But both of those are unnecessary if timesyncd is already running. It's related to timedatectl. Using cron and ntpdate is just ugly, even if it's highly recommended on StackExchange. Ugh.
- Sigfox already covers largest cities in Finland and the most populated regions in general even outside major cities. The triangle between Helsinki, Tampere and Turku.
- MergerFS FAQ. Once again, so many solutions for the same problem. How to allocate bunch of files on multiple drivers, without using RAID 0, etc. and keeping drives with independent file systems. Allowing recovery and reading drives individually.
- SnapRaid - Good stuff, had to read it all too.
- Configuring MergerFS was a real breeze. It took like a two minutes to get it up'n'running for a first time and working as wished. Awesome. As always, I'll do initial configuration and testing always in VM enviroment. So I don't mess up any systems with unnecessary junk, I don't want to keep, nor need to clean up.
- Wine 3.0 released. Yet I don't have even Wine installed. I don't have even mono installed nowadays. At some point I had it installed for a few projects. But as soon as those projects matured, native Linux binaries came out as well.
- Assembled a few storage servers from "junk yard" hardware. Works very well, and running the systems is really cheap, when only unused resources are utilized.
- Lol, urlscan.io service doesn't work with IPv6 only sites. What a fail. Even if they report IPv6 resources. If A record is missing completely, they claim that domain doesn't exist. What a lame fail.
- Happened to encounter NetNut site, while looking for proxy networks. Sure it seems interesting. Somehow this site fits very well in with the government agencies, sockpuppet social media profiles and government level astroturfing. Also it's immediately obvious that their network map is bogus. No sane Internet engineer would build such network. I'm just wondering why they call it business network. Because it's clearly designed for quite shady businesses. It's a tool which I would use for purposes like building Twitter botnet. Also they're publicly offering it? Maybe it's being already used by government operations. But it's bad if you run a network which is only used for single purpose. What's better 'cover traffic' than bunch of normal users? Sounds like a plan. Btw. They do mention 'web intelligence gathering', so quite clear.
- Web Cache Deception Attack revisited @ CloudFlare Blog. I don't know how much this is attack, ok. It just abuses blatantly ridiculous fails in configuration. Maybe it can be called attack. Sigh. World is full of issues like this.
