Yep, back home, I screwd it

Glad I'm not alone with the Refactoring === Breaking equality.

@bobthechemist Hehe. I've fixed, but. I think that yesterday it more or less worked properly because my PC was in good shape. But when the updates become too fast it all hangs

@bobthechemist A main loop approach would have been bettter :P. do you konw how scheduled tasks work? I mean, I think they are preemptive. Do you know what happens if the next one arrives with the preemptive link still busy?

I've only just delved in to Scheduled Tasks, and it's on the RPi so things behave quite differently in the realm of slow processors.

I know you can crash a model B RPi by attempting to start four scheduled tasks :)

Hehe

I think tasks get dropped when too busy

That makes sense. My qualitative observations indicate that the task is run no more frequently than the rate passed to CreateScheduledTask, but there's nothing guaranteeing that it will run at that rate.

@Rojo I think it gets queued.

    color = Red;
    StartScheduledTask /@ {
      CreateScheduledTask[Pause[10], {0.1}],
      CreateScheduledTask[color = Green, {3}]
      }
Dynamic@Graphics[{color, Disk[]}]

For me this code shows a red disk for ten seconds and then switches over to green, implying that color = Green was put in some sort of queue.

@Pickett True, same here

@Pickett However

color = Red;
c = 0; RunScheduledTask[
 If[c == 0, Pause[10]; c++, color = Green], {1, 2}]

never gets green

Separate tasks get queued, same ones get dropped?

@Rojo Yeah that seems to be how it works. Didn't think to try that.

Why JLink/Kernel/init.m is opened when one call <<JLink` ??

According to docs JLink/JLink.m should be.

What am I missing?

@Kuba Its one of those places where I think we just have to accept what WRI is implementing. What you are missing is the documentation and I honestly don't know whether and where this is mentioned in the official documentation. It's been like that for ages and I think I learned about it from Meaders book or something similarily aged...

@AlbertRetey I can accept MyTrash/init.m as a default directory I just want to see that statement after I type "packages developement" in search in MMA or wolfram.com.

@AlbertRetey But at least you've confirmed my thoughts, thanks.

well, the documentation :-). I usually find myself to try things out in such situations and it turns out that Mathematica tries pckgname/Kernel/init.m, pckgname/init.m and pckgname/pckgname.m in that order and treats the file it finds first the same in all cases, namely Needs won't complain if any of those contains BeginPackage["pckgname`"] ...

@AlbertRetey The fact that experienced people like you have to "try" things to be sure how developement environment is working is disappointing. But I should probably use stronger words than "disappointing".

Anyone have the following problem with WC: if I'm logged in, I get a "you don't have permission" to view messages; however if I sign out, I can read the same messages.

Perhaps this is their read-only-maintenance mode and it's not clear from the error message.

@Vaggelis_Z Hi!

@belisarius Hi!

@Vaggelis_Z Are you in Greece now?

@belisarius Yes.

@Vaggelis_Z How is that going? Is the govt. getting support from the people in the negotiations?

Or are they going to surrender to the EU?

@belisarius I hope not. This is the first left party government in our history and they are radical.

@Vaggelis_Z But (at least from the media) they aren't pursuing a total break in the relationship with the EU

or that is what the Germans are telling to the media

@belisarius People here cannot tolerate any more austerity but they also afraid to leave the eurozone. I personally think that it would be great to return to 2001 and in our national currency.

@Vaggelis_Z Well, the EU is favoring the banks, not the people. That is very transparent now. Spain, Ireland, Island, Greece ...

Germany and France got the best part of the cake and the rest got leftovers and financial breaks

@belisarius Yes, but Spain, Portugal and Ireland have conservative government who like to bend over to Germany!

@Vaggelis_Z Spain will probably switch to the left quickly. They are suffering a lot. Portugal not sure. Ireland probably not.

@belisarius Greeks believe that if we abandon the Euronone then we will suffer like Argentina back in 2000. However I don't share this opinion.

The problem when switching left is that you're mostly alone, like we were. But we suffered before switching. The switching was a consequence of the suffering. Until recently our economy was in a 10 years constant recovery. Then came the punishment from the "first world". Supporting left wing governments isn't allowed :)

Now we are relying all our exports and imports in China. And that is a dangerous thing.

@belisarius We love the Germans as much as you love the British! Is this correct?

@Vaggelis_Z Well, that depends on who you ask. Britain was our historic economic master (like in master/slave), but the USA replaced them in the 70's. Anyway, England was very involved in Greece for the last 200 years too!

@belisarius Well I was referring to the 80s and the Falkand war!

@Vaggelis_Z nah, that was a right-wing war dream executed by a decadent military coup. Only stupids (but there are a lot) supported that. It was a stupid move and England was at that time considering a peaceful mixed government transition for the islands. They were too expensive. That was before oil and a fishing paradise were discovered there.

@belisarius Over the past months the media here shown a lot of the Argentinian history so as to know what will happen to as if we leave the eurozone. Is this true that import is prohibited? For example you buy cars that are assembled there only?

@Vaggelis_Z Nope, that never happened here. The media is trying to terrify the people, as always :)

@belisarius I suspected that ...

The are restrictions on the imports, mostly based in the world banking denying international credit. But not prohibitions

We had a lot of debts, and the current goverment was committed to paying them all, to end the economic dependency. That was a "red alert" for the international banking system and they decided to make the government suffer and fall.

They are almost succeeding ...

@belisarius A particular media channel claimed that for example German cars (Mercs, BMW, etc) are not imported in Argentina and the locals buy only cars that are made in the country.

@Vaggelis_Z German cars were never massively imported here, for whatever reason. I think they were always too expensive for the mean income. But you can see a lot of Japanese, Korean, Brazilian, American ...

@belisarius Brazilian car?? Name a brand!

@Vaggelis_Z Brazil has very developed car industry. They don't have local brands, but for example Ford make cars there, and a lot

VW too

@belisarius Now it all make sense!

@Vaggelis_Z It's like if the media here publish that Greece don't import japanese tuna. Of course not. It is nonsense

@belisarius And what about inflation? If I am right the Mexican peso is stronger currency than the Argentinian. Anyway, you have very cheap gas there, while I have to pay a small fortune to fill a 100L gas tank.

@Vaggelis_Z Inflation here is mainly driven by monopolistic companies and is very difficult to fight. The government found a lot of corporatist resistance and they think forcing it is like risking democracy, so they accepted a lot of pressure and turned back to more moderate positions instead of pursuing a more socialist setup.

@Vaggelis_Z Mexican economy is by now an appendix of American economy. They just gave the Americans the power to manage their economy at will.

@belisarius Our national currency back in 2001 was inflated but nothing like the drachma of the 1950s where the largest printed bill was astronomical. Would you like to make a guess' of that bill?

@Vaggelis_Z "make a get" ?

oh ..

:)

@Vaggelis_Z Nah, we were there too in the 70's and 80's. Small countries need strong governments or they fall like prey to the market forces

/. "market forces" -> "vultures"

@belisarius But I guess that you never had a printed bill of 100 billion peso!

@Vaggelis_Z No, but for escaping that possibility we needed to change our currency several times. dividing by 10^4, by 10^6 by 10^3 ...

and that happened on several ocasions

so, yes, we were there too

@belisarius That also happened here, three times if I am correct.

@Vaggelis_Z Well, I remember four

@belisarius You'll probably right!

@Vaggelis_Z What are the main Greek industrial produces now?

@belisarius Well, I have to go now; time for dinner!

@Vaggelis_Z Ok, nice to chat with you!

Good luck!

@belisarius We don't make almost anything!

@Vaggelis_Z ha! that's the international division of work! Poor countries must remain poor. That's it

@belisarius But we don't need to make anything now. We made a lot of magnificent things in the past when other civilizations were hanging from trees eating bananas!

@Vaggelis_Z Yes, but you can't make cars out of the Parthenon!

@belisarius Yes, but I bet Ford stole the inspiration of cars from ancient Greeks!

@Vaggelis_Z The Romans took the Greeks as teachers. Ford takes them for slaves. There is a big difference :)

@belisarius Indeed! Nice to chat with you. I will try to join here more times in the future.

@Vaggelis_Z Same here! Good luck with all that brilliant future!

@rm-rf You around?

yes

@rm-rf Hi! What do you think about posting a question on Meta for guiding beginners on the site's usage, recapping things like the image uploader, the scripts, how to copy code to the site, not using subscripts, MWE, etc. Is there something like that already done somewhere?

That sounds good. I think people started something somewhat similar but nothing materialized.

@rm-rf I can try something using the pitfalls question template, leaving others to answer on different aspects. Sounds good enough?

Yup

@rm-rf Ok, thanks!

Good luck!
