1841  Other / Off-topic / UK: got paypal? on: February 12, 2011, 10:40:28 PM
Hey,

I need to buy a part for my laptop, but the guy ONLY takes paypal. I've tried several cards already and they give me various stupid errors (or redirect to main page or need 7 day confirmation .etc)...

Anyone here able to let me xfer them 10 through internet banking and then they send the 10 to him for me? Trusted members only (don't want to get scammed :p)

Thanks

1843  Bitcoin / Development & Technical Discussion / file_lock in python/Qt on: February 12, 2011, 10:03:57 PM
Hey,

So I want to detect when bitcoind is running but that RPC server hasn't yet started up.

The way bitcoind checks whether it's already running is by using boost::file_lock
http://www.boost.org/doc/libs/1_35_0/boost/interprocess/sync/file_lock.hpp

Any ideas how to use this in python? I could create my own binding for python but I'd rather not have a compilable dependency for such a minor thing.

The problem with checking a systems processes is that it's unreliable to assume the program is always called bitcoin (i.e different server implementations).

I tried a different file-lock library:
Code:
$ bitcoind
$ sudo apt-get install python-lockfile
$ python
import lockfile
lock = lockfile.FileLock('.bitcoin')
with lock:
    print lock.path

'.bitcoin'
$ cd .bitcoin/
$ python
import lockfile
lock = lockfile.FileLock('.lock')
with lock:
    print lock.path

'.lock'

Any ideas how to do this? Must be cross-platform. File locking is an OS function, so maybe I'm not using the correct file?
1844  Bitcoin / Bitcoin Discussion / bubble imminent on: February 12, 2011, 07:09:33 PM
Yesterday night there was 1.1 BTC per $. This morning it was 0.9 BTC per $ briefly.

- Small core community.
- Not many services. People mainly using bitcoin as an investment vehicle.
- Sharp increases in value.
+ Linux users tend to be idealists and not invest in something because of money necessarily.
+ Lots of outside interest recently.

I conclude a large chance of a bubble soon happening.

1846  Other / Off-topic / laptop power jack on: February 12, 2011, 07:14:52 AM
I did a bit of investigation and came across this page,                                                                                                        

http://www.laptopjacks.com/view_part/LG-Laptop-DC-Power-Jack-LG41225.html

Part Number: LG41225
Center pin diameter: 2.5mm
(and lists my laptop there as LG P300)

However my laptop has 5 contact points whereas that picture only has 3.

I then saw this power jack which I believe is the same type,
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=400145746359

What does that metal cover do? For the description of another unrelated power jack, I saw "If your old jack has 3 pins only, you can easily remove the metal shield covering the DC Jack" <- so why do I need it?

meh... any suggestions? I found half of the power jack I need... now it just needs it's winter jacket.

as to what else people will do:
participate in a knowledge economy where everybody gains instead of competing in a zero-sum one.

western population is decreasing. that's why governments import clever brown people (immigration). most growth estimates for humans place a cap. where the cap lies differs according to various risk estimates,



there's an interesting effect that newly urbanised countries shop drops in fertility and more as they become developed. many western countries are still shrinking far below 2.1 children per family which is the replacement rate.

so overpopulation is not a worry for me. esp since no government agency finds it a worry either.

also the UN predicts that famine will in a few decades disappear... currently most food shortages in the world today are the result of dictators and war.

Yeah adapting our environnement is cool.  But there is a limit to that.  We don't live in deserts on earth.  We don't even live on water, although we technicaly could, I guess.  There is just no benefit in doing so.

There ARE fringe people who live in the sea and in deserts!

http://www.bbc.co.uk/iplayer/episode/b00rrd85/Human_Planet_Deserts_Life_in_the_Furnace/

(worth watching those documentaries btw- one of the best documentaries I've ever seen)

- Nomads who navigate by means of sand dunes in the Sahara for 2 weeks to find tiny water wells.
- Men digging 10m underground linking km's of tunnels to get flowing water.
- People who live on boats their whole lives. Some boys even have eyes more adapted to see underwater than on land.
- A man that hunts deep underwater for up to 5 mins.

Now tell me that the human race isn't the best race and capable of anything!

It is just *not a place designed to sustain human life*.

The Earth is no more designed for us then we ourselves fit to it. The difference between man and the other animals is that we don't spend millions of years evolving to adapt to our environment, we fit our environment to us. Shaping Mars for habitation is not incredulous, and places well within the bracket of extremes people experienced through history.

The issue here is your own mind, not our abilities.

that intro vs the senate committee is not fiction and actually happened. that character is based off Robert Zubrin.

The real version is far more dramatic,

His plan named Mars Direct has been adopted by NASA for their Mars Design Reference mission by the mid 2030s and can be done within NASA's current budget over 10 years.

This is a video of how such a mission would look (Mars Direct),

forget mining. It's too much of a hang-up for new people when it's a minor thing (for them). If they need to know more they can do research to find out.

Quote
Bitcoins are associated with cryptographic public keys controlled by the person who owns them. To transfer them to someone else (i.e. to make a payment) he broadcasts on the Bitcoin network a digital signature identifying the bitcoins he is transferring, along with the public key of the new owner. This information is stored in a distributed database maintained by the Bitcoin network that records the public keys that own every bitcoin. Bitcoin software validates the digital signature and updates the database to record the new owner of the bitcoins. He will then be able to transfer them to someone else in the future.

Maybe you don't realise how technical sounding that is. Let me highlight all the problem language:

And it's very hard to follow.

I'd rather pick 4 core ideas, forget everything else and drive those sole points home. No need to talk about the distributed blockchain, public keys or mining.
1856  Bitcoin / Bitcoin Discussion / Core ideas of Bitcoin on: February 11, 2011, 12:07:32 AM
What are the core ideas? Don't get bogged down in details- it's for non-technical people.

- Distributed. We set the rules.
- Microtransactions.
- Transactions cost nothing.
- Anonymous

How would you phrase this to the common man? I've heard the gold farming analogy for mining, but how about for everything else?

How would you best explain distribution while allaying any security fears?

you come here to argue. you don't need to use schoolchild fallacy put downs. if your argument is strong enough then state the facts.

Prove to us that government force actually provides more favorable conditions than a freer society. Prove to us that prosperous people should truly owe their prosperity to the current state-of-affairs, if you will.

I suspect that you're young and maybe a little inexperienced in discussing these matters with somebody who disagrees with you, but let me explain why I will ignore that paragraph.

The first part is a classic example of begging the question:
http://en.wikipedia.org/wiki/Begging_the_question

It is also filled with loaded terms.

Finally, a hypothesis or theory cannot be proved. The best one can do is to try to disprove the null hypothesis.
