thank you again torsten.
you saved me a lot of work there.
the workshop went quite well, btw, the audience was enthusiastic.
sadly though it was very small too. the kids were more interested in IoT and
android workshops than learning smalltalk.
i need to work on a more capturing introduction for next time.
or maybe look into smalltalk for robots or something like that.
greetings, martin.

(slack is probably the best tool for this) then it's just a matter of finding a good time that fits everyone. maybe two or three times will be better if pharo gets more than a few students. however, having everyone join the same meeting helps show everyone how much others get done, and generally should help foster community. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

[Pharo-users] smalltalk banner or poster for FOSSASIA conference.
hi, as i have been working on smalltalk projects within FOSSASIA for Google Summer of Code and Google Code-In, as well as run smalltalk workshops at the FOSSASIA conference, i have been invited to run a small booth and put up a banner about smalltalk. details about the conference are here: http://2016.fossasia.org/ since time is short, i wonder if a banner design for pharo already exists, that i could use. alternatively, a poster, that can be stretched, or two posters on top of each other. if there is nothing ready, maybe the design that was posted to the list most recently can be stretched into a banner. my workshop this year will be using roassal, so something about that would also work, or other smalltalk topics, like squeak, etoys, etc... it would of course also be nice to meet other smalltalkers in singapore next month. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

(it's optional, in the sense that you can declare a type as "mixed" which can be anything, so just like typescript, and how python and ruby will be once they have optional types) greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

[Pharo-users] More fun with Roassal: 1st iteration of a Roassal Mindmapping tool
Excerpts from stepharo's message of 2015-08-22 09:55:04 +0200:
> would be fun to see if you can reuse the algo of roassal.
i have taken a stab at that:
===
view := RTView new.
| activenode prevnode |
view
when: TRMouseClick
do:
[ :ev |
| label node |
"node := shape element."
label := RTEditableLabel new
height: 30; "i have a very high resolution and like
large fonts"
text: '';
element.
node := RTBox new
color: Color white;
borderWidth: 2;
borderColor: Color black;
element.
node @ RTDraggable.
"select a node to branch of new nodes from it"
node when: TRMouseClick do: [ :click | activenode := click
element ].
"if the label is empty: '', then its size is 0@0 and is no
longer clickable to edit, hence we make the node clickable
instead"
node when: TRMouseDoubleClick do: [ label shape
showTextMorphFor: label ].
node when: TRMouseLeave do: [ label shape hideTextMorphFor:
label ].
view
add: node;
add: label.
RTNest new
stretchable;
on: node nest: {label}.
"when the label changes its size, the box doesn't update its
size unless we add this workaround"
label trachelShape addCallback: (TRExtentCallback new block: [
:aShape :ratio | node trachelShape extent: aShape extent + (20 @ 0) ]).
node translateTo: ev position.
"label shape showTextMorphFor: label." "this opens the node in
edit mode,
but somehow messes
things up"
(activenode notNil and: node ~= activenode)
ifTrue: [ prevnode := activenode ].
prevnode
ifNotNil: [ edge := RTEdge from: prevnode to: node.
edge
+
(RTBezierLine horizontal
withContinuousRectangleAttachPoint;
yourself).
view add: edge ].
prevnode := node.
activenode := node.
view signalUpdate ].
view.
===
the behavior is a bit different than the usual mindmapping tools as it does not
enforce an automatic layout but you are free to place nodes whereever you like
by just clicking in the location and moving the node later.
that behavior is inspired by a mindmapping tool called labyrint:
https://github.com/labyrinth-team/labyrinth
https://www.youtube.com/watch?v=Pv3dTovGc0E
thanks to alexandre bergel and others who helped me to figure out some
problems such as a workaround for RTEditableLabel not working with
RTCompositeShape:
shape := RTCompositeShape new.
shape allOfSameSizeWithPadding.
shape add: (RTBox new color: Color white; borderWidth: 2; borderColor: Color
black).
shape add: (RTEditableLabel new height: 30).
the remaining problems are cosmetic. for example i can't seem to get the nodes
to open up in edit mode. doing that with the commented line in the code above,
wrecks havoc on the node.
i also would like RTBezierLine to be horizontal or vertical depending on how
the two nodes are positioned to each other. and it should always start at the
middle of the rectangles edge at a 90degree angle.
lastly, i'd like to have rounded corners on the RTBox.
if/when i develop this further, i plan to add the ability to select multiple
nodes and add edges between them. be able to move selected nodes as a group,
and align selected (or all) nodes according to one of the layouts provided by
roassal (tree, circle, etc), things like export to svg or png would also be
nice.
and of course, package it up...

Re: [Pharo-users] [OT] Bill Gross: The single biggest reason why startups succeed
Excerpts from Esteban A. Maringolo's message of 2015-07-23 16:51:10 +0200: What I think we miss here, is the generation of the users adopting Pharo/Smalltalk. For many developers over they 30's (like me), when I show them Pharo or tell them about what/how it does some stuff, they get curious and/or try it. They might even learnt Smalltalk back at the university. Usually they have used/suffered a lot of languages or tools and can appreciate the benefits of Pharo, as well as to identify its shortcomings. that's a good point. i also fit into that group, picking up smalltalk because i want to expand and get a different perspective on how development is done. When I talk to new programmers (20-25 years old), almost all of them don't get attracted by it. Why? I couldn't tell. Mainly because they can't use the few tools/patterns they already learnt how to, barely, use. yes, the problem with people coming out of school. they expect that school adequately prepared them for future jobs, thus assume that what they learned in school is enough for the rest of their career. it takes several years of working for reality to sink in. Those kids will grow up and besides doing non-toyish software, maybe will lead teams or get to make decisions about what technology to use. Maybe we should ask ourselves what technologies do startups choose to invent new solutions? Why? whatever the lead tech happens to be familiar with. and if they are not familiar with anything then they'll use rails. Software became pop-culture some years ago, and I feel we're Jazz/Classical. I like the latter, but trying to attract pop being classical is a dead end. totally. it is exactly the feeling i have about smalltalk and lisp. i learned both because i wanted to know if the newer languages everyone is using are really any better. i'd expected that they would learn and improve over older languages. but i had to discover that that's not the case. i used to believe that languages like python, ruby and pike were a new generation of languages that improved over the old languages like c and c++, but i was disappointed and had to find out that the innovation already happened a few decades earlier and almost everything else following was a step backwards in some ways. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
[Pharo-users] [OT] Bill Gross: The single biggest reason why startups succeed
Excerpts from S Krish's message of 2015-07-20 17:47:50 +0200: Check out this amazing TEDTalk: Bill Gross: The single biggest reason why startups succeed http://on.ted.com/h15YB meh. read the transcript if you want to save the time, but to save even more time, here is the summary: The number one thing was timing. Timing accounted for 42 percent of the difference between success and failure. Team and execution came in second, and the idea, the differentiability of the idea, the uniqueness of the idea, that actually came in third. ... The last two, business model and funding he talks about the need to assess timing, but unfortunately doesn't tell much about how to do it, which is really the crux of the matter. in hindsight it is of course easy to see how the timing factor applies. but before, it's like trying to predict the future. and then, how does that relate to pharo or smalltalk in general? how can we assess the timing for pharo's success? did smalltalk miss its chance, so we should give up? or is it still coming? glass bowl anyone? there is no actionable advice in there. what shall we do? wait, and we'll know the timing is right when we see it? the only advice i can extract is that, because we can't predict the timing, don't put all eggs in the same basket, and while pushing pharo, don't push so hard that the future depends on the push to succeed. instead make sure that the project can continue even if the time is not right, so that it is still alive when the time is finally right. to actually make an attempt at prediction we'd have to look at developer needs. what are developers needs now, and does pharo deliver to fill those needs? (i believe it is pretty clear that pharo is still missing a few things, mostly on the integration side with other systems) can we predict what developers will need and expect in 5 years, and can pharo develop to match those needs? these questions are dear to my heart because i am asking them myself for my own project. i believe, i have a solution that many developers need, but as far as i can tell most developers are not aware of the problem yet. i hope that in time they will become aware, and that by then my project will be ready and thrive. we'll see. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

[Pharo-users] pharo looses font settings on linux with retina screen
hi, i am running pharo 40614 on linux on a mac with a retina screen. i have not tested this on a normal laptop yet, so i don't know if the retina resolution is the problem or the pharo version i am using. probably a bit of both. the worst issue is that when i restart an image, the font settings are partially lost and reverted to the original size, which is to small to read on such a screen. and restoring the font size requires me to reopen all the affected windows. there are also issues with some widgets not resizing to the full size of the font, making the text only partially readable. and then there are widgets that have the correct size, but the font remains small. and all that is not consistent, sometimes all sizes are correct, sometimes it is a complete mess. pretty much every time i restart after resetting the font size i get different results. it makes pharo practically unusable on this machine, because i am spending to much time fixing fonts, and am not getting any work done. is there some other setting to adjust to the resolution besides selecting a huge font? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

But that may be a lot o work so I can only dream about it, as nobody has time for that (me included). Well, as I said elsewhere, Smalltalk doesn't work like that: code has to be lived in the image for most tools to work properly... it doesn't really have an editor of file mindset, but an object inspector mindset. the interesting thing is that i don't think git is the problem here. a git repo does not need to have a working tree. smalltalk git tools could read the code directly from git using git-fast-export and write them with git-fast-import the effect would be that the working tree is now only in the smalltalk image, and git would be a pure storage of history. any use of external tools on the repo would happen on a clone and be pushed into the repo that smalltalk uses. that would however be a complete break with filetree.

(which is not yet supported (i have an idea how support could look like though)) i don't mind file-per-method though, it helps to make the diff-stat more readable, showing which methods have been changed, added or removed... ... that folks should be looking at tools support (like Thierry) ... this is where the real work needs to happen ... good tools can hide the disk fomat completely so why does the disk format matter ... I am personally not really a fan of this; I've been using git for a while and I am perfectly content with using command line on the disk (maybe I'm rare breed); I have yet to see a GUI/tool that would come even close to the power of command line, but I've been using Linux for a long time. except for displaying the history graph. can't beat gitk or other gui tools for that. having a smalltalk version of that graph would really be great! As I've said to Thierry some time ago in different thread, I would be interested in idea of having everything on disk side and Pharo would only somehow refresh it's content (just like a Java IDE / text editor would). can't you already do that, except that you need to manually update the image by loading/adopting the current state from the repo? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Re: [Pharo-users] Get OS uptime
Excerpts from Norbert Hartl's message of 2015-03-19 14:09:28 +0100:
That's my point. Or better I like to know how the plugin can distinguish
them. Usually there shouldn't be a difference. I know the /proc filesystem.
It is what unix is all about. Make every information available as file. You
say it is a virtual filesystem? Yes, but there are only virtual filesystems
in linux. Below is always a device driver accessing disks, cdroms, etc.
Memory or the kernel does not make a difference. They are all the same and
they should according to unix. So I still not understand the problem.
files in /proc are not seekable.
that or something related may be the problem.
compare this strace:
/proc/uptime:
lstat64(/proc/uptime, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
open(/proc/uptime, O_RDONLY) = 8
fstat64(8, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xf722e000
fstat64(8, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
_llseek(8, 0, [0], SEEK_SET)= 0
_llseek(8, 0, [0], SEEK_SET)= 0
_llseek(8, 0, [0], SEEK_SET)= 0
_llseek(8, 0, [0], SEEK_SET)= 0
close(8)= 0
/etc/profile:
lstat64(/etc/profile, {st_mode=S_IFREG|0644, st_size=1750, ...}) = 0
open(/etc/profile, O_RDONLY) = 8
fstat64(8, {st_mode=S_IFREG|0644, st_size=1750, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xf722e000
fstat64(8, {st_mode=S_IFREG|0644, st_size=1750, ...}) = 0
_llseek(8, 0, [0], SEEK_SET)= 0
read(8, # /etc/profile\n\n# System wide en..., 1750) = 1750
_llseek(8, 1750, [1750], SEEK_SET) = 0
_llseek(8, 1750, [1750], SEEK_SET) = 0
read(8, , 4096) = 0
_llseek(8, 0, [0], SEEK_SET)= 0
close(8)= 0
/proc/uptime comes with a filesize of 0, and this, pharo tries to read 0 bytes
from it.
or rather, since there is no read() call, it concludes that there is nothing to
read.

Excerpts from Thierry Goubier's message of 2015-03-09 13:13:23 +0100: There is technical limitations in adding that information (or using it). I did use it a long time ago at the beginning of gitfiletree, but it was prohibitively slow, even on small git repositories. i find this puzzling. when monticello creates the archive, is it not the version somewhere accessible in the object? it has to come from somewhere, doesn't it? filetree (i believe) writes the version and history into PackageName.package/monticello.meta/version i assume you tried reading that? is that what is slow? was the problem to check out the version in order to get the file, or was there a problem reading it? I would have been pleased by a Package-Author.Commit.mcz approach however, but the numbering scheme in MC is so hopelessly broken and unreliable anyway that it's not worth the hassle. The only thing correct in MC is the UUID, but, except in very specific cases, it isn't used because it's too costly to check it. because the mcz needs to be unpacked to get it, i guess? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Any suggestion??? how exactly are you trying to load it? One more thing i want to ask, i.e, how to make .extension files (like .class files) in pharo. what do you mean? when code is saved with filetree (or gitfiletree) each class is a directory, with each method as a file. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Re: [Pharo-users] GSoC mentor assistance for FOSSASIA smalltalk projects please
Excerpts from Sean P. DeNigris's message of 2015-03-06 05:15:23 +0100: Martin Bähr wrote i'd like to ask if anyone is willing to help me mentor those projects. I can probably help you with Offline text search (my preference) or possibly file editor and asset manager. wonderful! offline text search is the more interesting project of the two for me as well. at the moment though it is just answering generic questions about how to get started with pharo. we'll see next month which projects will be accepted. Two questions: 1) Text Search mentions in a specified directory on the mobile device, but the rest of the description sounded like a desktop app. Which is it? Mobile would add quite another dimension. Maybe a web app could be doable, but IMHO a native mobile app is probably outside the scope of a GSoC project. whoops! that is a copy paste error. for exactly the reason you mention i have a separate project to just make a mobile app with the same specs. (i'd love if it could be done in smalltalk, but that's not going to work yet) i fixed the description. thanks for catching that! 2) File Editor talks about editing assets, the list of which includes images. Do you expect to be able to edit images from within Pharo, or did that apply to the text-based assets (which most were)? General image editing within Pharo would be really cool, but sounds like a big job... i am fine if just text editing works. image editing could be solved by just making it easy to load a new image. i'd appreciate if you could join the fossa...@googlegroups.com list http://groups.google.com/group/fossasia and help answer the students initial replies. which is basically: download pharo, look at tutorials, start reading pharo by example and look for spec questions on the list. for the editor project i also have http://societyserver.org/mbaehr/training/ where i show how to store a static website in an image, and the basic idea is to make that editable, and also add a control panel for the server, similar to the one for seaside. this would make a nice add-on package for zinc. so far most students are interested in the search application... next week i am off for the FOSSASIA conference in singapore, (where i'll give a workshop about building a REST api with Zinc-REST) so i'll have little time to check email. if you could help especially in that time, i'd really appreciate it. after the conference students will start to make proposals and in april we'll decide which roposals to accept. things should be more quiet then. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Re: [Pharo-users] BaselineOf vs ConfigurationOf

We have the feeling that it is not used (or not a lot) and we think to replace it with another mechanism (for example, let the user define his/her 'favorites' classes / packages). how is that different from user defined groups? what i find important and useful about 'last modified classes' is that, as i work on many things, not only pharo, when i do get back to pharo, i can go: ok, where was i? then i click on 'last modified classes' and remember. without that i have to find some other way to remember before i can then type what i need to find the right classes. it may not be much, but having an easy way to see what i have been working on just feels more comfortable. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Re: [Pharo-users] how to debug zinc server errors from tests
Excerpts from Sven Van Caekenberghe's message of 2015-01-30 07:59:00 +0100: when debugging a zinc server with tests structured as in http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/ i am wondering how to best debug errors in the server while running tests. one test makes a ZnClient connection to a testserver started from the same test. the test fails with the server returning a 500 error. Writing a unit test using both an HTTP client and server is already a bit tricky sometimes, having it fail is always ugly. This is more a threading issue than anything else. I usually will do as you describe: rerun manually with a server where debug is enabled. ok, unfortunately i now am facing an issue that i can not reproduce manually. i suspect that is because of a difference between the test server (started in withServerDo:) and my actual server. i could probably set up a clean image and retry it there. how can i avoid that and run a clean server instance manually in my dev image? It could be an idea to try to improve the situation, but it won't be easy. To enable a debug/continue style the client request should first not time out (which is not a good idea for unattended tests), then something should be done about the UI thread. well, i am glad they time out, otherwise i believe the image would be locked up. the timeout should be paused though while the debugger is running. so the problem is really that the test would need to run in a separate thread so as to not block the UI? but to do this, the whole test-running framework would have to be changed, and it's not something i can do in the test code? what about a hack to instead make a shorter timeout? let the test fail immediately, then the UI can bring up the debugger, i can inspect the issue, fix it and rerun the test? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Excerpts from Sven Van Caekenberghe's message of 2015-01-30 07:53:46 +0100: This microframework is quite handy for REST API (and the README of the repo is *really* useful) http://smalltalkhub.com/#!/~zeroflag/Teapot So many options, there is Zinc-REST as well... i am aware of both. i want to take a look at Zinc-REST first though. i looked at Teapot briefly. i am not a fan of routing all urls from a central location , i prefer a way where i delegate a namespace say /people where a class then is responsible for what happens within that namespace. iaw: if i go to /people/person/2 then the HandlePeople class would be called with the argument person/2 or even #(person 2) this allows me to map a REST api to an arbitrary object hierarchy, where the base urls are only defined by the hierarchy which itself is not even aware of REST, and once the object is located i only need to connect the REST interaction to it and have it work the same way regardless of where in the hierarchy that object actually lives. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/

Excerpts from Mayuresh Kathe's message of 2015-01-25 22:42:37 +0100: is there any email client with imap + smtp support available under pharo at the moment? problem: due to compute power constraints, i am running pharo as my only application via xinit, having to constantly switch between pharo and console (for mutt) is becoming painful. :) another approach to that problem (which i am interested in) is to have a terminal within pharo. take a look at http://smalltalkhub.com/#!/~OS it now supports unix/linux and includes a terminal. it's in the pharo4 config browser. i don't know how well it works (a first try to start a terminal hangs the image :-( greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] improving print-it in playground
Excerpts from Ben Coman's message of 2015-01-25 04:55:45 +0100: I am still looking for concrete use cases why people need to see the printout in the editor. Could you provide an example of when you need it? Here is one I just had. I wanted to select the result of this... Object allMethods detect: [ :m | m senders size = 1 ] so that I could press the shortcut key for all senders on it to view that code. shortcuts and mouse-clicks should work on the popup as they work on a selection. i had a case where the popup was to on the right edge partly off the screen that the inspect icon was not accessible. a problem in itself, but being able to use short-cuts as normal would have helped. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
[Pharo-users] comparing FileReference
hi, i can't seem to figure out how to normalizethe path of a FileReference i am trying to compare FileSystem disk root / 'local/lib' with Filesystem disk workingDirectory / '..' but they don't match because the latter produces: File @ '/local/lib/pharo4/..' i'd expect to be able to compare two references as equal if they point to the same directory on disk, regardless of the path getting there. is there any way to accomplish that? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] Popular
Excerpts from Ben Coman's message of 2015-01-23 08:56:58 +0100: In addition, I consider running on pure 64-bit OS to be critical to gain credibility in the wider community. yes, i was quite surprised to find that 64bit is not supported yet. in my case i had to pick all the 32bit dependencies by hand to make it work which was quite an effort. So how do we target experts? * Experts are probably more suspicious of hyperbole and cheer leading. * Experts are in demand and busy - so short targeted concrete examples would be good. * Maybe quickstart tutorials demonstrating foundations for different application areas * Web (e.g. http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/) definitely! for me this is the tutorial that had me hooked into hacking on pharo. * Games * Business GUI * Business RDMS App * Demonstrating Pharo's tight debug/compile/resume workflow oh yes! greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] Mea Culpa
Excerpts from kilon alios's message of 2015-01-22 08:13:57 +0100: Popularity indeed comes with a high price. Guido the creator of python he has said in one of his presentation that there many people who want to add their libraries to python distribution but they should not want to do that, because once a library is added it become very difficult to change since so many people depend on it to keep backward compatibility. He claimed that even simple bug fixes have to go through lengthy review process. This can be expanded to the entirety of the IDE and the language. This the most important reason why pharo has been moving forward so fast and why popular languages move at glacial speed. I dont want to lose that so yes I dont want for pharo to become popular. squeak already hast that 'problem' i believe and pharo is actively working to counteract it by removing less important things. so i doubt pharo will suffer from the pressure to fill it up with new packages any time soon. in this case it may be a win for all because those who want backwards compatibility can choose squeak, and those who want fast paced action may use pharo. also craig with context is working on minimizing the images which i believe should help to move more and more things out of the core, allowing you to pull them back in, making it possible to choose from various versions, based on your compatibility needs. ironically, i actually expect to want backwards compatibility in the future. but backwards to now, not to a decade ago, so i hope pharo development will eventually slow down somewhat. in addition, the multiple smalltalk implementations also act as a stabilizing factor, because people will want to write code that runs on all of them. (seaside for example) so pharo can't go that far out of line and make itself completely incompatible. i am also not sure which is better. a large standard library makes for a more stable system. having lots of important 3rd party libraries can lead to dependency issues... greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] improving print-it in playground
Excerpts from Tudor Girba's message of 2015-01-19 08:33:04 +0100: I worked with Andrei to find a solution for improving the print-it support. You can take a look here: http://www.humane-assessment.com/blog/improving-print-it-support-in-gtplayground have not tried it yet, but i wondered about this problem. as mentioned elsewhere, i too would like this in every textbox. most notably in the debugger where i do a lot of print-it to find out the value of some expression. i'd also like to pick up on the idea that when there is no selection the whole line will be evaluated (btw, there is a typo, you wrote like), and that line will only be highlighted. the idea is great, but what about if i do evaluate a selection? could in that case the selection be turned into a highlight? there is no way around to make a selection in order to evaluate it, (unless some form of shift-control-whatver-key+mouse selection is introduced) but once evaluated it is clear that i didn't intend to select to replace the text, and i'd like to avoid doing so accidentally. also, would it make sense to keep the highlight until another piece of code is evaluated? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] Stackoverflow, was: [Pharo-dev] Could we keep Pharo-dev for Pharo-dev?
Excerpts from Daniel Lyons's message of 2015-01-15 19:47:22 +0100: The Prolog section does pretty well by having a small but significant community that watch the Prolog tag like hawks. something like rss2email could be used to forward stackoverflow questions to the list, so that they'll be noticed by more people to be answered. The big advantage of Stack Overflow is that googling your question finds it there with an actual answer. yes, when i search for a problem on google, stackoverflow search results are my favourite choices to look at. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] pharo at google code-in
Excerpts from Martin Bähr's message of 2014-12-24 19:48:47 +0100: i have been meaning to learn smalltalk for a while, but i always lacked a good project that i could do with it, until recently. and figuring that teaching is the best way to learn i put up my projects as tasks for google code-in as part of FOSSASIA which is a code-in mentor organization. i posted a write-up of the smalltalk projects and tasks here: http://societyserver.org/mbaehr/learning-smalltalk-with-Google-Code-In i'll be updating that as students work progresses and if i add new tasks. i am also still looking for tutorials that can be used to start learning pharo. in particular for spec and desktop apps in general, but i don't mind having more options for webframeworks too. so far i have 4 students started on smalltalk, one of them didn't continue after the tutorial (so i reopened the task for others), and one who is learning amber. we'll see if any of them pick up the actual project tasks. greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org BLUG secretary beijinglug.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
Re: [Pharo-users] pharo at google code-in
Excerpts from Hernán Morales Durand's message of 2014-12-25 17:24:18 +0100: a desktop application that can search a given collection of text and browse the search results. Do you have a prototype screenshot for the UI? A mockup? It could be interesting to see what do you expect to see. i don't have any mockups. the UI is very simple. in the final version i expect the following: some intro text about the application, a search-box and a selection of categories, a directory to browse the contained documents without searching. when pharo starts, this should come up automatically, and any development tools should be invisible. in part that means, the world menu should be hidden and only accessible through a keyboard shortcut, or ideally only available when pharo is started with an extra commandline argument (eg --devmode) the user can then browse the documents or search. search results should be a long scroll-list and clicking on a result should expand the document at the location where the term was found, allowing to scroll back and forth from that point. the initial version will only support plain text, but future versions may support html text to allow for cross-links in documents. a generic use-case would be something like an encyclopedia. it has lots of articles in various categories, and it makes sense to deliver it as a complete application with all assets contained in the image. there is also a mobile component which is essentially the same idea but designed for a mobile phone. this is currently being worked on using javascript/phonegap to be cross-platform. i don't know if pharo can run on a mobile phone. i'll explore that when the desktop app is functional. I would only list the one that are maintained. Because it is not fun to work with dead projects. agreed, however iliad happened to have a very good tutorial which included serving static files, which is one of the features needed for the website. Iliad is not unmaintained and is not a dead project. Please subscribe to the Iliad mailing-list to keep updated of latest changes. We are exploring options to migrate the old web-site to a new server. I am integrating changes for working with modern (responsive) CSS frameworks. that is good to know. it is an interesting project. i didn't see much traffic in the google group, and with the website down and no updates to the code on github for years or visible release announcements it is difficult to get a good impression. what is missing to get the website back up? just a host? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.secaudium.net societyserver.org BLUG secretary beijinglug.org foresight developer foresightlinux.orgrealss.com unix sysadmin Martin Bähr working in chinahttp://societyserver.org/mbaehr/
