Why don't you guys take your discussion to a new thread and leave this one for the OP's question?


That's a good point Norm please who has the rights do a fork the  OT  stuff

At risk of getting sent to MD, the Italian bankers who took money were called that because they sat on a bench, so both meanings of bank have the same origin.



Good that one Campbell ; Which bankers are you referring to exactly?

Yeah sorry about that but i too haven't the paper ready on desktop to copy past an address i had to search it ... and it is implied when one have better things  to do first do those things  and then when have time/will etc go here or there

e.g. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.140.5068&rep=rep1&type=pdf . . . .

Is that a peer‑reviewed paper? What has that got to do with the design of BlueJ? It is an assessment after BlueJ had been written, which is different from what you said earlier. You still haven't yet shown any evidence that BlueJ was designed scientifically.



I guess we can't understand each other right now ; Please take a look again in my previous message

Cmon Campbell please you are not a starter open one you want if you're interested; they're not books are at max 10 pages each or so  

Update: e.g. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.140.5068&rep=rep1&type=pdf and please abstract about the tool(BlueJ) and focus on the pedagogical issues referred in the papers

also can't find it right now but  here was a  thread where Junilu talked with a Uni prof about teaching /learning issues that's somehow the start in the set of issues actually some of the teaching board seems to support

Please find some evidence for that;



take a look on papers in the citeseerx  link up

I think you will find the design of things like BlueJ was much more empirical than researched.



Well that's arguable(as I mentioned use the scientific method i.e. a mix experiment + research but we can't say is an  already finished work with scientific probing power --for some practical reasons mainly--) but anyway the important point here is that  in recent years there are people sensible(more than the traditional ones) on teaching/learning issues and Koelling and company almost  has started and continue a path and IMO that's better than before (or nothing) isn't ?

Daniel Demesmaecker wrote:I started learning using an ide and found it actually verry helpfull, especially in the beginning,



I too although back then IDEs(as we know it nowadays almost not existed) was considered "boosted" text editors like Stallman's emacs instead the very simple ones(without syntax  highlighting, formating, connection with a compiler ecc)

often when first writting code you're aware of the fact that something excist but you can't remember the name or something like that in those cases are the dropdowns of an ide when you start typing verry usefull. Also the autogenarating of code(like constructors, getters & setter or the toString), optimizing the imports or formatting your code are super helpfull.


Yeah i know all that but a teaching/learning method is based on struggle to remember(i.e. the "hard way") new things and an IDE not helps on that method but on the other hand an IDE as you have already mentioned can potentially be helpful on learn things trough repetition mean you not struggle(i.e. the "soft way") at start to remember new things but you repeat more times those things --your IDE "takes memory" for you-- without any struggling. Is demonstrated that learn things trough repetition and not struggling takes much more time

In other words the hard way presupposes you have to be based only on your memory and not on tools(automatisms, helpers) when learning new things. That's the reason people on education field have almost scientifically(empirically+ some research) proved and  designed simplified(compared to Eclipse and company) IDE's for teaching/learning (but also for small scale programming) like BlueJ DrJAva ecc

E.g.for BlueJ(teaching OO trough Java language) take a look here

Note: after all we're not talibans on impose one way instead of another in teaching/learning the important thing is find and apply the more effective, painless and efficient way a student can get the subject matter. That's all

If they not did it till now maybe they wait some volunteers do it for them  

Maybe they hope we'll al read the Java™ Tutorials.



That's a HUGE source of (applied) knowledge everyone have to pass on regardless (but that's unrelated for a new learner  exercise/simulate with a simplified API)

A personal preference is a personal preference and it is not discussed at all especially when one has experience

Of course, if you use an IDE you never actually write imports; you simply choose the class you want from the dropdown list and the imports are all sorted out for you.



Yes and that automatism while helping productivity of an experienced user that has a job to finish does not help when one learns

The reason we don't like going straight to an IDE is that some people find it overloads their brains. Not everybody. Not most people, least of all when the IDE is taught well. But it would be wrong to start by overstressing a minority who might make good programmers and disheartening them so they give up.



I quote you at 101% (an IDE IMHO have to be used last in the learning chain) and add one more thing
Consulting Java's API (similarly to IDE overwelming issue) as is actually from a learner perspective is an issue because has too much detail was not a bad idea if some volunteers (mostly i guess) decide to "refactor" it  to a more simple one only for learning purposes; I notice some book's author's started to do it in their books(pointed to newbies) but was not bad at all if one can find a simplified Java Api directly(independetly from his(her) textbook) in Oracle's site

I think the old "Don't use wildcard imports" rule should be understood in context. I never saw any problem with wildcard imports since I don't often run into the issues they can cause. On the rare occasions that I do, my IDE will typically help me figure out where the name collisions occur...


Junilu that "temporary rule" is valid only for who haven't any experience with Java's  API and have only pedagogical scope(also the "rule" to not use an IDE in the very first steps) in the sense that you have to learn search/manage the API and memorize the class names (typing in import clause helps) included in what package etc(for a newbie API's consult  is really overwhelming) . On the other hand problems as that one can occur . But all this hopefully  is only for a limited period in time

Do you contribute with the computing power of your computer-smartphone-gameConsoles-networks to scientific research e.g. through BOINC or other distributed computing platforms? And in case, what projects do you choose to support and why?

Paul take a look at  What Is Software Design and Why Is it Needed?

I don't thing Quora(like Fb or Google) be a small scale project; regard your link i take a look tomorrow or when i have free time

The problem i notice is that almost all people in all places(here too) talk about coding dissecting code ecc and only very few(if any) talk about design; and the problem IMHO starts just from Uni's education

Thanks Corey i guess i got what you meant and really appreciate

I casually found an interesting article   Designers Will Code what you think about ?

TIA,

I'm too and have a plentiful RL as Tim tell you here's no a direct connection between those two concepts. So seems you have to find a solution on that problem out of the programming world . I can affirm also that sometimes programming helps cope with RL 's problems and the opposite is also valid
If you articulate better (more precisely) maybe we can talk/think something about it ;)

So, Greece? )



Tim wasn't so difficult the quiz isn't? the characteristics are alas clear and straightforward Yes there's my actually place (except if you know another place with > 6K islands etc)  

But I thought most such countries people deal with high taxes by dodging them.



Long story short you're right but that's not the correct way to go and I put the responsibility to the state (top down approach--mean system-- not bottom up--mean not individual--). The proof is : an individual who goes to live in another(more organized) state conforms to new states's laws and above all is happy wirh his new state; when the same individual returns to his crappy system start behave as before(with some additional problems because now know the difference between a good system and a bad system)

That's a very interesting theme for discussion we can write a tome about it so let's discuss it in another occasion.

I remember when was younger a place near Vienna Austria dunno what humidity was(very very low) back then but impress me the fact that i needed only 3 hours of sleeping to equate the normal 7-8hours; i loved that)

Yep, sounds like Florida, the State that Air Conditioning Made Possible.

It really is the humidity, not the heat. The record high temperature for Tampa, for example, is only 99°F. Or at least it was until recently. All bets are off now. But you can die from the insufferable heat in Tampa. Afternoon rains up here are usually about 5PM. Down there, it always seemed to simply get hotter and hotter - and muggier and muggier - as the sun went down until the whole world was a steaming dark blanket.

It's about 4°C outside right now. We're at the bottom of a cold snap and it's just about dawn. Although normal around here in the previous century would have been closer to 0. I used to expect the first serious freeze about December 24. Last year, I think I ran air conditioning in January. If not, at least was severely tempted to. And I like it a lot warmer than most people.



Actually I live in North Greece in a region called Macedonia( the real one not the fake one=FYROM see also  FYROM naming dispute. The Actual  Greek government is in process to give they a new name "North Macedonia" dunno why(my idea is because some strong states  US, Germany, Russia support them for some politico-stategic reasons and press to that direction for three decades so far) --historically not fit at all-- but that's it  ) Great Alexander's land and climate is like FL's as i can understand(near half December to March we've normally snow here). And yes humidity is a great enemy

Harry Kar wrote:Hopefully here in EU we haven't all that bad(and dangerous) natural phenomena thunderstorms, hurricanes and the likel and yes beaches are here too nice places ever and above all you can find beaches with warm waters too (i remember Atlantic was too cold for my taste) ;)

It's warmer on this side. The Gulf of Mexico is one big shallow solar-heated bathtub. Warm water leaves it and wraps around Southern Florida, passing up the state in the Gulf Stream, and eventually makes Europe a lot warmer that its latitude would otherwise warrant. Most Atlantic hurricanes come from either the Sahara or from the Southern Caribbean, move West, then North, then East and eventually become sub-tropical, often dumping on England and Ireland.


Interesting the round climate do, I lived some years in Italy and haven't noticed any strange phenomena except subtropical climate in Sicily island

But I think one storm did try to barrel up the Mediterranean last Summer.



Yep you're right but nothing to do respect those we see  (in news) frequently happens in US

Harry Kar wrote:That one looks weird ; Scandinavia has the best State of Justice system world wide AFAIK so far and  they go to N.America and we Mediterraneans go there(Scandinavia)  makes no sense to me



Well, a map a few years back showed that the #1 state that Floridians emigrated to was Alaska. There's a change for you. But a lot of the immigrants came here in the 1800s and earlier and they often picked a place with similar climate and farming conditions to what they knew back home. Cincinnati was popular with Germans because it reminded them of the Rhine valley. Locally we have a lot of Arabs, but they're not Muslim, they're descendants of Christian (Orthodox) emigrants from Ramallah. Ramallah back then was minority-muslim but prosperous, so a lot of people established business interests elsewhere and eventually moved. Only recently have we had an influx of Muslims, but a lot of them are not Arab, they're Pakistani, Bangla, or SE Asian.



Ramalah i guess is in Syria?!
Very interesting peoples migrations world wide

Obviously many people like New York. It has culture, lots of business. And pizza.


Harry Kar wrote:Italians are spread everywhere

That's because they bring the best food!



I can confirm that (my ex wife is Italian) but they're the most renown WW but  there are also other Mediterranean eating cultures (maybe less renown but the same valuable) like Greek, Spanish and french too. The Keyword in that field (as a very first abstraction) is: Mediterranean culture --for foods-- regardless of states    

Harry Kar wrote:we leaved out Alaskan's and Canadians but that's for the next trip

Canada is a great country.



Dunno why but i have that opinion too; I guess Canada(by the way Australia too) belongs to set of those  who has "of the best State of Justice system" like Scandinavia

Too cold for tropical me, though.


Miami vice ; between too worm and too cold i prefer the later only because i can't  undress my skin
