What we in fact see is that the object that "barely travels any distance at all" is the spent shell casing. This is completely fine as the aim is not to magically embed the spent shell casing into the target. That is what the projectile part is for. The projectile is likely to have whizzed off as expected, albeit not with great accuracy.
As for the general usefulness of plastic firearms, even if they can only fire a few shots, there are clear advantages.
1. You can obtain a firearm without it being registered to you or exposing yourself to criminal firearms dealers/police sting operations.
2. They are less detectable.
3. You can melt and/or burn the murder weapon with ease.
The tone of the video is a bit odd. It's comes across like a video trying to convince kids not to play with fireworks. It's not as if we all have loads of ammunition laying about here in the UK just waiting for a 3D Printed gun to come along so we can finally have some fun. Making something that can fire a bullet (at least here in the UK) is not the main obstacle to a working firearm. The main obstacle here is obtaining the ammunition.
When a UK journalist gets mugged though, he gets star treatment
Most news organisations operate in the same non-objective way whether they are government controlled or completely commercial. They report more favourably on their host country (and allies) than on enemies. For example, the BBC will report on Iranian police violence against protesters very harshly. It will be implied that the police violence is extreme and unwarranted and the unarmed and peaceful nature of the protesters will be emphasised (with protester violence even being ignored). In contrast, the same kind of violence perpetrated by UK police will be reported very differently. It will either be under-reported ("Police scuffled with protesters") or the focus will be on protester violence.
All you have to do to see this for yourself is do a search and replace on country/city names in articles. Suddenly that article damning Russia for the Seige of Grozny will be an article damning the US for the Seige of Fallujah. You will notice that sentences like "What right does the US have to order the citizens to leave." are quite jarring and do not seem like the kind of thing the news would normally say in this situation. This is your clue that something is very wrong with mainstream media reporting.
Forget the mail-man. Read the letter.
The vast majority of industry trade shows look quite professional. A small minority of industries that attract people with developmental problems (automobiles, guns, and games) don't.
I can't speak for the "vast majority" of trade shows, but many of the energy industry shows I've been to have had "booth babes". It is quite a common tactic (not the only one, but common nonetheless). It's about catching your eye. This can been done with brightly coloured displays, animated signs, movement etc, but with a large male patronage, attractive women seems to be effective.
If we are going to damn some companies for being so "stupid" or exploitative that they require beautiful women to attract men to their products, then perhaps we should also damn them for using other cheap tricks like bright colours, flashing signs etc.
Is it really wrong for attractive women or men to exploit their good looks for commercial gain? How about a man exploiting his natural physical strength for financial gain? Is it really so much better to be exploited for your brain than for your body? Being exploited for your brain can be very demeaning indeed. If I could earn good money standing around smiling at a trade show, I'd certainly consider it. Perhaps I'd feel exploited, I don't know, but I've certainly felt exploited in software development jobs I've had.
If you're taking any other approach, namely one that will force your client to remain attached to you I'd have to question your ethics, motive, and ability because what you're doing is creating a dependence on you that is borderline blackmail (if that's something you're doing).
Why is it that employees are supposed to work hard, be as professional as possible, take pride in their work, be ethical etc? All these virtuous practices are things that largely benefit the employer. It's effectively work ethic propaganda that has been drilled into the population.
In contrast employers work you as hard as possible for as little reward as possible (often including unpaid overtime which is effectively theft of your time) then dump you for a cheaper college graduate at the first opportunity. Employers do not adopt a strategy that benefits the employee as much as possible, they adopt a strategy that benefits them as much as possible. Why then shouldn't employees be just as ruthless, conniving and unethical as employers?
"Virtuous" work ethics have been drilled into successive populations over the aeons by those who directly benefit from them, i.e. the powerful. Don't fall for them.
How can the people support or oppose Chavez's policies if they don't even know what he's doing?
Well if they watched the privately owned media in Venezuela, they will certainly have no idea what he was doing. The hugely powerful privately owned media spent most of the time writing stories about how he is insane or a criminal. It was the private media that took an active part in the coup attempt against Chavez in 2002. There was plenty of incredibly critical coverage of Chavez in Venezuela, make no mistake about that.
The weird scope rules and lack of proper object/class support drive me up the wall when working on projects with ~40,000 lines of code.
certainly nowhere near as much as what their strangely negative reputation in the U.S. would lead you to believe
There was a lot of propaganda against Al Jazeera but it really was just nonsense. The US and Allies had grown used to their own media's kid-gloves reporting on their military adventures and were absolutely incensed that a news outlet would question their motives and/or pay too much attention to their victims. Al Jazeera has really been a breath of fresh air in the world of news media. They cover issues that are simply ignored by other outlets and have become one of my primary news sources.
I'm not saying Iron Dome isn't successful, but given that targeting missiles is very difficult and we are relying on official IDF sources, there should be much more scepticism about the system's effectiveness.
