Sure, the internet is more practical, and the odds of being caught in the time required to execute a decent strike plan, even one as vague as: "we're going to Amerika and we're going to hit 50 high profile targets on July 4th, one in every state" (Dear NSA analyst, this is entirely hypothetical) so your agents spread to the field and start assessing from the ground the highest impact targets attainable with their resources, extensive back and forth from the field to central command daily for 90 days of prep, but it's being carried out on 270 different active social media channels as innocuous looking photo exchanges with 540 pre-arranged algorithms hiding the messages in the noise of the image bits. Chances of security agencies picking this up from the communication itself? About 100x less than them noticing 50 teams of activists deployed to 50 states at roughly the same time, even if they never communicate anything. HF (more often called shortwave) is well suited for the numbers game. A deep cover agent lying in wait, potentially for years. Only "tell" is their odd habit of listening to the radio most nights. All they're waiting for is a binary message: if you hear the sequence 3 17 22 you are to make contact for further instructions. That message may come at any time, or may not come for a decade. These days, you would make your contact for further instructions via internet, and sure, it would be more practical to hide the "make contact" signal in the internet too, but shortwave is a longstanding tech with known operating parameters.

It is common in the military to give commissioned rank to certain positions for the higher pay grade. The fast tracking takes away from the belief everyone serving with you went through (roughly) the same basic training as you.

trying to be reddit 2.0

That would be 1 in 4 users and that's just not accurate at all. What you mean to say is 25% of Windows users still use windows 7. Its still an alarming statistic, and no wonder bruteforce cyberattacks are still so effective today considering it hasn't received security updates in like 10 years. I sincerely hope those people aren't connecting their devices to the internet like, at all. I'm fairly sure at this point even using a Debian based distro is better than sticking to windows 7.

Bit misleading. Tumour-associated antigens can very easily be detected very early. Problem is, these are only associated with cancer, and provide a very high rate of false positives They're better used as a stepping stone for further testing, or just seeing how advanced a cancer is That is to say, I'm assuming that's what this is about, as i didnt rwad the article. It's the first thing I thought of when I heard "cancer in bloodstream", as the other options tend to be a bit more bleak Edit: they're talking about cancer "shedding genetic material", which I hate how general they're being. Probably talking about proto oncogenes from dead tumour debris, but seems different to what I was expecting

Sure: for professionals. However when casually commenting in a forum it is fine because the reader can go check the citations (and perhaps come back and add to the thread).
