[Pharo-project] Preparing image for deployment [WAS: How to disable development tools on Pharo 1.3]

by Usman Bhatti

Hello all, Esteban, I took up the package for preparing a deployment image and I am testing it.. It works fine for blocking access to the development tools and debugger... I placed the package in the ss3 repo here: http://ss3.gemstone.com/ss/PrepareImageDeployment (you're one of the admins). Two things where I need help: 1. How do we disable the right-click menu (yellow-button menu) in a text editor? 2. While running deployment preparation code, I have a problem with cleaning monticello repositories... there is a KeyNotFound problem with TAddTest .... the process stops at this error. I have tried debugging it but couldn't find any clues; and the blockage of developers tools does not help much... I am attaching a screenshot of the problem, may be somebody has an idea... thanx in advance, usman [image: Inline image 1] On Thu, Feb 2, 2012 at 2:32 PM, Esteban Lorenzano <estebanlm(a)gmail.com>wrote: > Hi Noury, > > I packaged what I have.

It has worked extremely well with Squeak/Pharo, is robust, persistent, and simple. Realistically we're not going to move to Spoon over night, so what to do about a 37Mb changes file is a pressing issue. Being able to compress with history and/or write a new sources file with compressed history makes sense. It's not being unimaginitive or regressive, or anti-innovation; merely pragmatic. > > -C > > -- > Craig Latta > www.netjam.org/resume > +31 6 2757 7177 > + 1 415 287 3547 > > > > -- best, Eliot

[Pharo-project] Fwd: [squeak-dev] Re: Project ideas for GSoC, 7 days left!

by HernÃ¡n Morales Durand

Name: Big data CSV parser plugin Level: Intermediate Possible mentor: ? Possible second mentor: ? Description With the advent of inexpensive DNA microarray technology, big data is now available to many small and medium laboratories which performs statistical analysis based in microarray experiments. Most of the times the data produced by genotyping services is delivered in CSV format, as it represents a currently cross-platform "standard" which is easily readable, and still used in hundreds of business applications. In Smalltalk we have several CSV parsers but the performance is far from being competitive with libraries implemented in other languages. The goal of this project is to measure time execution and build a plugin to access CSV data in a fast and competitive way. Technical Details Currently exists several open source projects which implements C functions to access CSV data. The challenge of this project is to learn tools like VMMaker and Interpreter Plugin classes to develop a Squeak/Pharo internal or external plugin. Benefits to the Student The student will learn about interfacing highly efficient libraries to Smalltalk. Benefits to the Community The Smalltalk community will gain a winning library for a extremely common task like dealing with CSV files. Name: HDF5 support (http://www.hdfgroup.org/HDF5/) Level: Intermediate Possible mentor: ? Possible second mentor: ? Description Hierarchical Data File 5 is a new (1998) format capable of storing large and complex amount of data, and it is used in Gravitational and Plasma Physics, Earth Science research, Weather Services, Software Engineering, Biomedical Informatics, etc. As new data adquisition hardware is providing bigger datasets (for example, sequencing data) the need to query and access metadata, partial and full datasets in an efficient way (parallel I/O) is more important. In this format data are stored in a hierarchical format similar to the UNIX file system, and the data model supports a rich variety of data types and data space organizations. Currently exists APIs and wrappers for Java, .NET, Python, C and FORTRAN. The goal of this project is to build a wrapper to enable to access HDF5 data in Smalltalk. This binding could open Smalltalk to a lot of science domains and users in which currently pure object technology is unknown. Technical Details The student will need to learn details about the HDF format as data sets and composite data types. Benefits to the Student The student would learn about efficient data systems, implement an API, and experiment with large scientific data in Smalltalk. Benefits to the Community The Smalltalk community will attract more users by keeping in touch with big data analytics, by providing access to an efficient data format used currently in research and business. 2012/3/5 Janko MivÅ¡ek <janko.mivsek(a)eranova.si> > HernÃ¡n and Karl, can you or someone else develop your ideas a bit > furher, by answering the questions: > > description > technical details > benefif for student > benefit for community > > while potential mentor can be choosen later > > Thanks! > Janko > > Dne 02. 03. 2012 21:38, piÅ¡e karl ramberg: > > Make web browser plugin of Squeak work better on all platforms. > > Get Etoys image to run on CogVM. > > > > Karl > > > > > > On Fri, Mar 2, 2012 at 9:36 PM, karl ramberg <karlramberg(a)gmail.com> > wrote: > >> Port OpenQwaq video to Etoys > >> > >> Karl > >> > >> > >> On Fri, Mar 2, 2012 at 9:17 PM, HernÃ¡n Morales Durand > >> <hernan.morales(a)gmail.com> wrote: > >>> To dream is easy: > >>> > >>> -HDF5 (http://www.hdfgroup.org/HDF5/) support like PyTables or h5py > for > >>> Python > >>> -Information Retrieval/Full Text Search package like Lucene > >>> (http://lucene.apache.org/) > >>> -A binding to R or SAS or SPSS > >>> -Better or more semantic web support (see > >>> > http://en.wikipedia.org/wiki/Web_Services_Resource_Framework#Implementations > ) > >>> -An omnibrowser for OWL ontologies > >>> -CSS template system > >>> -Support of a Distributed Hash Table protocol like Pastry > >>> (http://www.freepastry.org/) > >>> -Workflow system with designer and plug-in architecture (see > >>> http://www.taverna.org.uk/) > >>> -Big data CSV parser plugin > >>> -Plugin for fast approximate search in strings > >>> > >>> cheers, > >>> > >>> > >>> > >>> 2012/3/2 Janko MivÅ¡ek <janko.mivsek(a)eranova.si> > >>>> > >>>> Hi everyone, > >>>> > >>>> 7 days to deadline for ideas of this year GSoC!

The libraries you keep and why are those libraries that the embedder wants to use, or that support the libraries that the embedder wants to use. The VM very much determines the efficiency and complexity of such an interface. Issues such as does the garbage collector support pinning, or does the interface support call-ins from multiple threads, very much affect the design of an interface, and hence its ease of use.

If one has a useful library in Smalltalk and a client in a C/C++ language, then embeddability is one way to provide that library to C/C++. Rolling one's own socket-based connection is another, but fraught with complications. Basically embeddability does provide something useful in the right context (hence my employer wanting me to implement it). That in no way indicates that dynamic language systems shouldn't continue to improve themselves. And being able to embed might mean that occasionally a Smalltalk application gets much wider use than might otherwise be the case. > > On Wed, Mar 7, 2012 at 12:14 PM, Lawson English <lenglish5(a)cox.net> wrote: > >> >> >> On 3/7/12 2:36 AM, Igor Stasenko wrote: >> >>> On 7 March 2012 08:36, Lawson English<lenglish5(a)cox.net> wrote: >>> >>>> [...] >>>> >>>> Igor, you're familiar with f-script? >>>> >>>> http://www.fscript.org/ >>>> >>>> not really, why asking? >>> I know there's plenty of alternatives.. >>> And how do you see f-script could help us? >>> It is objective-c (or Mac ) oriented.
