Re: [Pharo-dev] [Vm-dev] vm crash when using rairedTo: with fractions

by Tim Mackinnon

Is there a way for this to get back into 6.1 - so we can shoot for a stable 6.x version that will last us for a year while 7.x is under development? Iâm not familiar with how point release are handled in Pharo, and I get the impression that this is going to be a slightly rockier year as there have been some pretty revolutionary changes made to get us here. As its a vm change does this mean we get 6.2 queued up somehow?

Re: [Pharo-dev] Anybody using Orca Smalltalk to JavaScript?

by Frank-B

Hello Craig, upfront thank you very much for being willing to respond to my problems and questions. As I tried to make clear in this and the neighboring thread: http://forum.world.st/PharoJS-crashes-at-first-try-td4960686.html I am looking for a serious "professional" solution to combine server-side Smalltalk with client-side JavaScript, which is sourced in the same Smalltalk image that runs the server. This is an essntial part of all of my product plans and ideas. I am only in software for mass-markets (Fremium principle) and not in customer-centric projects like most Smalltalkers. Another important background: My quite large Smalltalk famework contains the greatest parts of the data that defines the UI and, second, I have very specific plans for the UI in the long run, because the UI decides mostly about the success or failure of an application software. There are currently three "candidates": ST2JS, Orca and PharoJS. As you can read in the second thread (see link above) the PharoJS image failed at first attempt. Therefore my question, are you aware of a working image? Second, is there anywhere some detailed information available about what PharoJS does and, at least basically, how it's done? (Side-remark: This part is excellent for Orca, I recommend the Orca papers. Brilliant concepts!) Third, are you aware of real-life solutions based on PharoJS? I am currently still at the very beginning of my investigations and my very first impression of PharoJS was the worst possible: The trial image failed at first attempt and, even worse, neither general documentation nor code/class comments were available. Both are a no-go for me, being a "documentation fanatic" out of very long experience in software development. Thank you in advance for a short comment.

Oh, I'm plenty comfortable discussing it on the Pharo lists. :) I was referring to different context in which someone asked me a question here, and I got attacked for responding to it.

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. Never heard of the 80:20 rule? > even wrote a bit of documentation myself Great! My congratulations. It's hard to suppress the irony in my brain! > Investing means making decisions. 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).
