Janko 1-Dec-2009 [15098x2] | If I knew how it would be I would prepare more light talk , with some cool stuff , only little code and more visual .. like doing a gui to post message on twitter all in few lines and typed in front of them . I had demo of this when I was preparing for talk |
I haven't been to many scietific talks so I didn't know :) | |
Henrik 1-Dec-2009 [15100] | (I also only learned this recently) |
Janko 1-Dec-2009 [15101] | I will be playing with some erlang soon , did anyone maybe yet work anything on the BERT serialisation .. http://bert-rpc.org/(it's the binary erlang term serialisation). BERT-RPC based on it also is very minimalistic , binary (so you can send over images or anything) , and has some really cool features ? |
Gregg 2-Dec-2009 [15102x2] | Talks often dont' go as planned Janko. I'm sure you did fine. For a less technical audience, I try to focus on how little code it takes to do useful things; and how readable that code can be. Having some simple GUI examples is important, because normal people don't want console apps. For programmers, I emphasize that REBOL isn't really a programming language; it's a messaging language. As Carl has said "It was designed for the semantic exchange of information between people and machines." So it's never REBOL compared to Python, or Ruby, but compared to those languages plus XML or JSON. |
I haven't seen anything on BERT, but Maarten has done some Erlang and may know. | |
Janko 2-Dec-2009 [15104x2] | It was ok.. I was not sooo satisfied with situation but I was satisfied on how I handeled it and it was ok. |
One collegue smalltalker that we meet at previous barcamp wrote me on twitter something like "this is bloody usefull :-)" after seeing the slides and code examples screencast on internet. | |
Geomol 2-Dec-2009 [15106] | I often find myself thinking about, how to categorize REBOL among other programming languages. I think, it's how the language wants us to make sentences and not just give commands, one on each line. In REBOL, we write: insert back tail series my-value and it feels natural. In other languages, you would do something like: int sz = length (series); Series *ptr = &series[sz - 1]; insert (ptr, my_value); You could maybe do: insert ( &series[length (series) - 1], my-value); but it's just far from being as elegant as in REBOL. So most languages are like simple commands all the time, one after each other. With REBOL we make sentences. It's like a huge step up from many traditional programming languages. |
Gregg 2-Dec-2009 [15107x2] | Yes. I think of this aspect as combing the best elements from Forth and Lisp/Logo in a natural way. That is, lists (blocks) are the foundation, and you build up a vocabulary to do what you want. It also encourages us to structure and doc things a little more, compared to Forth; but you have the freedom to express things any way you want. It's a very different view from Python, where (my opinion), the goal is to make all programs look the same, no matter what the problem domain is. |
Even with a simple example like the one you gave, I might add a couple funcs to make the intent even clearer. e.g. insert-from-tail: func [ series [series!] value index [integer!] ] [ insert skip tail series negate abs index value ] insert-before-tail: func [ series [series!] value ][ insert-from-tail series value 1 ] insert-before-tail series my-value | |
Janko 2-Dec-2009 [15109] | yes, this is very nice part .. I like that most things are expressions that you can combine together |
Oldes 3-Dec-2009 [15110x3] | Is someone using REBOL with Gmail? I was trying this: http://mail.rebol.net/maillist/msgs/44246.html but it does not work (I think that REBOL's esmtp scheme is not responding on STARTTLS command as described here: http://en.wikipedia.org/wiki/STARTTLS |
or is it fault of the Stunnel? | |
I think it's the right time to start writing some schemes for R3 | |
Janko 3-Dec-2009 [15113] | I remember from Factor irc where they tried to make smtp compat with gmail that gmail does something a little different that with regular ssl connections. I think it starts without ssl and initiates it in the middle of communications or something like that |
Sunanda 3-Dec-2009 [15114] | Can confirm I also failed to get stunnel to work with REBOL while following the advice in that post, Oldes.....Sorry, that's not much help, is it? |
Graham 3-Dec-2009 [15115x2] | I posted the changes needed somewhere to get esmtp to work with gmail .... needs R/command though. |
This script http://accessories.s3.amazonaws.com/hotmailer.r uses a secure pop protocol to login to hotmail and download messages, and remove attachments. Should work with gmail. | |
Graham 4-Dec-2009 [15117x3] | Speed or safety? that is the question. >> to-integer "" == 0 >> to-decimal "" ** Script Error: Invalid argument: ** Where: to-decimal ** Near: to decimal! :value |
>> to-decimal "0" == 0.0 | |
>> to-decimal "0 " ** Script Error: Invalid argument: 0 ** Where: to-decimal ** Near: to decimal! :value now it seems to me that if you're going to allow string input to 'to-decimal then the most likely instances of this type of data is where it has been parsed in or comes in via a form and so it should by default handle whitespaces | |
BrianH 5-Dec-2009 [15120x2] | In R3, the answer was safety: >> to-integer "" ** Script error: content too short (or just whitespace) ** Where: to to-integer ** Near: to integer! :value >> to-decimal "" ** Script error: content too short (or just whitespace) ** Where: to to-decimal ** Near: to decimal! :value |
You can clean up input. Accepting invalid input is another matter - that way leads to exploits. | |
Graham 5-Dec-2009 [15122] | as long as it is consistent |
Graham 7-Dec-2009 [15123x3] | Anyone run the Arm version of core on one of these plug computers ? http://www.globalscaletechnologies.com/p-22-sheevaplug-dev-kit-us.aspx |
I can think of lots of uses for them if they ran core ... | |
Some guy got Arc to run on one of these and setup a web server | |
Maxim 7-Dec-2009 [15126] | that is a cool server form factor :-) |
Claude 8-Dec-2009 [15127x2] | hi, i would like to know if R2 and R3 have a scheme for LDAP ? |
i would like to do Authentication with R2 !!!! is it possible ? | |
sqlab 8-Dec-2009 [15129] | maybe you should ask there http://softinnov.org/rebol/ldap.shtml |
Dockimbel 8-Dec-2009 [15130] | I've stopped working on it at alpha stage, I've lost the need for it in my projects. It would require some significant amount of my time to finish it, probably a week of work. I could spend so much time on a tool that I don't need only under contracted work. |
MikeL 8-Dec-2009 [15131] | Re: Claude's question, I am interested in knowing what R3 users plan to use for Integrated Windows Authentication support http://en.wikipedia.org/wiki/Integrated_Windows_Authentication . It is a show stopper for me for most uses in any corporate environment. |
Pekr 8-Dec-2009 [15132x2] | MikeL: I think that we are at the very beginning of such topics. You can read my marketing/strategy related material in Article REBOL adoption, and I reduced it to two words - EASY DEPLOYMENT: http://www.rebol.net/wiki/Marketing_Strategy_Websites |
To answer your question in more concrete manner - I think that we have to stop and prevent our past ttitude of "you can code it yourself". Many ppl who come or will come to REBOL, are seeking a solution, they are not interested to do the work themselves. I think that R3/Extensions open some door to link to many outer system. But the hard work still needs to be done. As we are a small community, I once again propose some kind of Bounty system, so that we can sponsor most popular requests. This should address one aspect of the problem - REBOL devs not necessarily working only for free ... | |
eFishAnt 9-Dec-2009 [15134x3] | In R2 core latest, I want to launch a script with args... |
launch %myscript.r argument1 argument2 ;so is this possible? (this line would be in another script | |
launch/as-is %myscript.r arg1 ;is not active in this version REBOL/Core 2.7.6.3.1 14-Mar-2008...but not sure it would do what I want. | |
amacleod 9-Dec-2009 [15137] | Anyone know if there is way to send faxes from comand line on windows...perhaps a dll (I've seen mention of faxcom.dll) |
Gregg 9-Dec-2009 [15138x2] | Steve, I always use CALL these days. Or Gabriele and Doc's async-call. By using system/options/boot, you can launch the interpreter you're running under. |
Alan, I haven't done it from the command line, but a quick search makes me think it might be possible using Windows Fax and Scan, if your on the right OS. I did a fax interface for Bo a few years back, but it used APIs. Graham may have thoughts here as well. He's done a lot with Hylafax I believe. | |
Graham 9-Dec-2009 [15140x2] | Yes, I use hylafax which runs on linux .. but a windows client just has to do a http post of the file to the hylafax server |
and in so much as rebol runs as a command line client, then it can be readily done. | |
Gabriele 10-Dec-2009 [15142x2] | Steve: call reduce [system/options/boot %myscript.r "argument1" "argument2"] |
when you use file! call does a to-local-file automatically, and wraps it in quotes. | |
sqlab 10-Dec-2009 [15144] | with launch you can probably come next to what you want with launch {-s --do " script.r arg1 arg2"} |
Graham 10-Dec-2009 [15145] | Launch is broken that's why Gabriele is suggesting using call instead |
sqlab 10-Dec-2009 [15146x2] | I use call too in my scripts, but the question was for launch.) |
Ok, this way launch works as I would expect launch {-sq" test.r arg1 arg2 } | |
