Re: [Pharo-users] Making STON exportation lighter

by Offray Vladimir Luna CÃ¡rdenas

Thanks Mariano and Cyrill for your answers. The reason for trying to make STON lighter is to use it as a document format for interactive notebooks. When I saved the notebooks nodes from the graphical interface their content become Text instead of strings and it generated a lot of format information with #runs, TextColor, and other information that was not necessary for the notebook and made the format heavy. I had problems trying to detect were the conversion from String to Text was taking place, so I added an extra message before serializing the notebook in STON that takes any node content and convert it from Text to String. After that I ended with notebooks that were 100 to 200 times smaller as was properly reported with the amazing commit message [1] :-) [1] https://twitter.com/offrayLC/status/712834911120572416 The next step is to made STON DVCS friendly by removing long lines [2] [2] http://forum.world.st/Citizen-example-for-manipulating-a-bibtex-file-tp4784… Cheers, Offray On 04/03/16 16:22, Mariano Martinez Peck wrote: > Not sure which is the reason of making it lighter, but you may also > want to use a compressing stream so that the resulting stream is much > smaller. > > On Thu, Mar 3, 2016 at 2:03 PM, Cyril Ferlicot > <cyril.ferlicot(a)gmail.com <mailto:cyril.ferlicot@gmail.com>> wrote: > > HI, > > There is a method in the class side of Object to override.

[ann] pharo consortium membership matching campaign

by Tudor Girba

Hi, The Pharo Board is proud to announce a special campaign for attracting new Pharo Consortium members during 2016: http://consortium.pharo.org/web/Membership A new fund has been created from which the Consortium will receive the equivalent of one yearly membership fee for every new member, and the increment in yearly fees for every upgrading member. For example, if a new company joins the Consortium as a Silver member (2000 EUR / year), the fund will contribute a one-time amount of 2000 EUR to the Consortium. Similarly, if a company upgrades from Bronze (1000 EUR / year) to Gold (4000 EUR / year), the fund will contribute a one-time amount of 3000 EUR. This campaign will take place until the end of 2016, or until the fund is depleted. Currently, the fund totals 21000 EUR, a sum which is graciously supported by three companies: - LabWare Inc (http://labware.com) - ObjectProfile (http://objectprofile.com) - feenk gmbh (http://feenk.com) This is an exciting development that paves the way to attract more industrial interest around Pharo. Please help us by spreading the word about this campaign. Cheers, The Pharo Board

Multiplying maximum server power usage times maximum dirty electricity generation CO2 emission gives overstated results. There is a huge drive for lower power consumption (because electricity in a data center is VERY expensive), to move datacenters to cooler areas, to power them with clean, renewable electricity.

Re: [Pharo-users] OpenGL project

by Dimitris Chloupis

Better name it "Pharo OpenGL ES" so people don't get confused why some of their OpenGL code does not work. You won't finds docs about it , the guy that made it rarely frequents this forums anymore and his code is based on a api that is no longer included and supported by Pharo because it was doing a lot of machine code stuff that was very hard to maintain. My advise is don't worry about backward compatibility , make it easy, make it simple. Don't be afraid to code some of it in C if you have to. Sometimes it's far easier to use C than Pharo. Pharo is no magic wand. And foremost ask a ton of questions. We love questions.

Yep sorry, here are the steps I used to make it run on OSX: $ brew install glfw3 $ cc demo.c -lglfw3 -framework OpenGL For other systems the doc is hopefully detailed enough (http://www.glfw.org/docs/latest/build.html) > Why do you say ?porting NBOpenGL??

It looks like a lot of work was put into this, can I find a paper about it? Also, IMO this all looks too complex. My point in limiting to ES 2 is not just removing functions, I want to make it look simple like the C demo! Thibault

Looks cool. Now to ask for more ;) Something like this would be nice to have integrated into Pharo, plus listing and filtering on For Review status, and showing and loading slices. cheers -ben On Fri, Mar 25, 2016 at 8:08 AM, Torsten Bergmann <astares(a)gmx.de> wrote: > Hi, > > played with the JSON API of Pharo FogBugz issue tracker with the outcome of > another little Pharo tool that lets you: > > - login to FogBugz from Pharo > - enter a string and search for according issues > - open a browser on a selected issue in the result list (works on Linux and Win so far) > > The project repo is at: > > http://www.smalltalkhub.com/#!/~TorstenBergmann/FogBugz > > One can use the client also directly: > > |client| > client := FogBugzClient loginUser: 'abc(a)def.com' password: 'secret'. > (client query: 'UFFI') inspect. > client logout > > You can download the tool in latest Pharo 5 (50660 or later) from catalog > or by opening the Spotter and entering "FogBugz", wait and hitting ENTER. > > Attached is a screenshot. > > Enjoy > T.

[ANN] Simple FogBugz Search tool in Pharo

by Torsten Bergmann

Hi, played with the JSON API of Pharo FogBugz issue tracker with the outcome of another little Pharo tool that lets you: - login to FogBugz from Pharo - enter a string and search for according issues - open a browser on a selected issue in the result list (works on Linux and Win so far) The project repo is at: http://www.smalltalkhub.com/#!/~TorstenBergmann/FogBugz One can use the client also directly: |client| client := FogBugzClient loginUser: 'abc(a)def.com' password: 'secret'. (client query: 'UFFI') inspect. client logout You can download the tool in latest Pharo 5 (50660 or later) from catalog or by opening the Spotter and entering "FogBugz", wait and hitting ENTER. Attached is a screenshot. Enjoy T.
