Not even that - they are just limiting what the bots can do.
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Indeed - like email spam, that kind of abuse just doesn't pay if you've got any kind of an overhead associated with volume.
Imaginary lines on the dirt mean nothing to stupid. Stupid is everywhere people are.
While I've been fortunate to have never received any of that junk, I do see this as a good move... and $5 is really low. Recall it's not $5 on any purchase, but $5 over the lifetime of your account. That's... well. If that's a problem for you, how exactly do you afford to have whatever it is you're running Steam on? I'll give you the internet - maybe public wifi (or stealing it)... but unless you dug the device out of the trash and are also stealing electricity, I think spending $5 at one time or another isn't much to require.
Ah, yes - they have those around here. Honestly, I don't listen to those, as (by chance) the stuff they play isn't anything I enjoy.
I can imagine though that it's perfectly fine for stationary radios - it's the mobile receivers who would deal the most with fluctuating signal strengths.
The way the digital stations around here work, is they broadcast both - and the receiver in my car seem to be intelligent enough to downgrade if the digital signal is too weak.
Basically, the radio starts off sounding like poo as it starts off in analog, but then as it 'locks in' (for lack of a better term) it switches over to digital and thus sounds much better. If I drive into a tunnel or such, the digital signal will drop and the radio will (without gap, mind you) drop back to analog, and switch back up when the digital signal is again stable.
I think what it does is it receives both, and keeps a running error talley on the digital stream. It uses this to determine if the signal is stable enough to use. I would expect even better performance if the streams were buffered for a second or two, but this isn't the case (at least the analog signal isn't - verified with my "real" radio)
Pst. Hey. Hey buddy. Your bias is showing.
It would be interesting to filter the results of a search with an expression - but as you say I think using the expression itself to drive the search is probably not something you'll see happen.
Privacy goes without saying, of course... but if I put a period or a comma in my search, I damn well meant it to be there. Pay attention to it.
Some of that mass cost might be made up for by simplified pipes and valves, though. Not sure how much you'll really save here, as you're probably still routing stuff around the bell for cooling.
Nowhere, because this is just a different mechanism to run the pumps in a normal liquid-fueled conventional rocket.
This does have some purpose - to allow you to restart the engine without externally running the pumps.
You still need ullage though, but RCS can be used for that.
That's the prior attempt - check the date.
... and why is that unusual? I use the same one at work. There's 3 just in that room and there's several rooms to chose from.
I find your signature incredibly relevant to your post.
