Craig Latta has done some strong work integrating Squeak and Pharo with the browser using a bridge derived from Bert Freudenberg's SqueakJS. Craig's work allows one to use Pharo running on the standard Cog VM, client side, to render to the browser, receive events from the browser, and manipulate the DOM.

Stephan > Perhaps you might want to explain to me the return on investment of the > Orca documentation then? Zero users, zero return on investment. What are you talking about?! a) The external documentation of Orca is brilliant. I have not yet had time to look into the internal comments. So your statement us wrong in this respect. b) I have no clue how many users Orca has. Only politicians and journalists are accepted to talk about things that they haven't got any clue of. I am neither of both. c) This is an university. Their purpose in life is to teach - and really also to research, but that has mostly been forgotten. d) The unique, wise and old German language, that we both speak, has a unqiue word for it: "Wissenschaft" but they mostly do neiher of both: no or little "Wissen" (knowledge) and no "schafft" (create). It seems to me that Orca is a great and rare exception to thus rule. read danisch.de to learn more. > I feel annoyed if you talk in absolutes like that, because I know that > there are lots of situations where creating documentation is a waste of > effort. a) If someone "feels annoyed" by statements and experiences of somebody else, this is only and exclusively the problem of the person who claims to "feel annoyed" - and in most cases a replacement for missing arguments and, even far worse, an attempt to suppress the freedom of speech. Why don't you ask your psychiatrist for help (yes, that was nasty, but it fitted in)? b) To every rule, there may be some exception. Here, they are not worth a discussion, in my opinion. > And I have also been bitten by lack of documentation. So you should rather agree wtih me! Why don't you? > And I have even been in a situation where both happened at the same time, > where a lot of effort was put in creating the wrong kind of documentation. > Oh, and I even wrote a bit of documentation myself.

Fully documented non-working code has no > value. Working code that no-one can use neither. Perhaps you ask for the cause(s)? Lots of people can't distinguish between cause and consequences. Perhaps this was the case when doc was missing? I don't know the cases you experienced. And I don't know any similar cases from my past, because ALL that was developed under my leadership was extremely well documented. > Your current communication is manipulative: you try to put yourself in a > dominant position by using absolutes, saying you feel sorry for me, and > bragging about your experience. That annoys me. If you want to convince > me, use arguments. 1) Fisherman's Friends has advertised over years at least in German (I do not know about other languages) with a phrase that has become a regular proverb in German: "Sind sie zu stark - bist du zu schwach" - Are they [here: my argument] too strong, you are too weak". So if you feel "manipulated" by someone stating his experiences from >35 years in software development, pardon, but that's only your personal problem, not mine! 2) The same applies to what you call "dominant". All the women that I have been affiliated closer with, did like and appreciated very much my very "care-full" (in the original sense of the word) but in situations, which require this, still somewhat dominant attitude. The word has always been my sword! 3) Finally: > If you want to convince me, use arguments. I have made my points very clear in this and the neighboring thread. Please just read it and try to understand (but I honestly doubt you want to). https://en.m.wikipedia.org/wiki/Nonviolent_Communication Of please don't come up with this lousy CIA organization that is full of lies, distortion of facts and suppression of truth (especially in history). This is the worst part of "LÃ¼genpresse" (even more the German version than the English one). I wrote here before: Truth is the new "hate crime". We are approching times of suppression that we Germans had twice before both by Socialists (same today) and behind both were the same people that want to silence us today again. I shall never surrender to this censorship and I detest eveybody who does! Habe die Ehre (if you know what Bavarians really mean with this salutation).

Perhaps you might want to explain to me the return on investment of the Orca documentation then? Zero users, zero return on investment. I feel annoyed if you talk in absolutes like that, because I know that there are lots of situations where creating documentation is a waste of effort. And I have also been bitten by lack of documentation. And I have even been in a situation where both happened at the same time, where a lot of effort was put in creating the wrong kind of documentation. Oh, and I even wrote a bit of documentation myself. I have been thought many things at university, and there were many more things I had to learn in industry. And from open source projects, which have other things to teach. Investing means making decisions. Fully documented non-working code has no value. Working code that no-one can use neither. Your current communication is manipulative: you try to put yourself in a dominant position by using absolutes, saying you feel sorry for me, and bragging about your experience. That annoys me.

Re: [Pharo-dev] PharoJS crashes at first try

by Frank-B

Stephane, thank you for your open words. 1) No I am NOT Frank Lesser and I will communicate this even clearer in a personal email to you. 2) I had tried to make very clear that I see the Pharo project very positive and my critics as being (at least intended) constructive. 3) I never care about my reputation. I only care about truth, facts and a sincere appearance. Few people appreciate this attitude and I do not value the others all too high or seriously. Unfortunately, we all have to live in these timees of universal lies, deception and fraud. You probably know the good German word "LÃ¼genpresse" and my version is: "the current Zeitgeist equals LÃ¼genpresse". 4) I have some good, solid and unusual ideas how I could improve the Pharo project considerably but for several reasons it is much to early to discuss this. It will take another 2-3 years and I will definitely come back when the time has come on my side. 5) As a contributor in the general Pharo sense I am currently neither capable (working 85-100 hours a week on my projects) nor eligible and the latter reason is not simple to explain, so I leave it at that for now.
