Re: [Pharo-project] Issue 3381 in pharo: project list

by Mariano Martinez Peck

stef, what about putting it under gforge? we can create a new folder for that. Let me know a suitable name and I create it and upload such slides. Do we have a svn for pharo also? cheers mariano On Sat, Dec 4, 2010 at 3:57 PM, <pharo(a)googlecode.com> wrote: > Status: closed > Owner: stephane.ducasse > > New issue 3381 by stephane.ducasse: project list > http://code.google.com/p/pharo/issues/detail?id=3381 > > Since I could not find how to upload a file I hijacked this issues > > Attachments: > PharoProjects.pdf 311 KB > > >

Re: [Pharo-project] Parsing and navigating Html

by Schwab,Wilhelm K

Stef, Do you at least have a list of specific applications producing the data? Do you know and trust the people running them? That might be a nice position compared to data mining the net (like Google) where you have no idea what might arrive, how well it might comply with standards, all the time having to worry about malicious intent. For example, I do not recommend putting untrusted data through a Microsoft parsing library ~:0 Bill ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of StÃ©phane Ducasse [stephane.ducasse(a)inria.fr] Sent: Sunday, December 05, 2010 10:21 AM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Parsing and navigating Html no just some applications I do not control. :) On Dec 5, 2010, at 3:21 AM, Schwab,Wilhelm K wrote: > Stef, > > Are the html pages produced under your control?

[Pharo-project] SampledSound>>storeWAVOnFileNamed:

by Schwab,Wilhelm K

Stef, I was trying to create a SampledSound from floating point data ("digitized" to signed words) and then save a WAV file using #storeWAVOnFileNamed:. Attempts to play the results on Ubuntu fail with a gstream error. I am wondering if the code might be promising compression and not delivering it, or vice versa. FWIW, attached is some code that I ported from my Dolphin image. The files that it writes play and look correct in audacity's graph view. If it has any value to you, let me know and I can try to sort out its lineage. I *think* it is code that I added to Dolphin by adapting a couple of methods from Squeak. Bill

I use SqueakDBX directly without Glorp connecting to a PostgreSQL database with about 50 million rows currently. I am storing minutes of financial data. Since my data is by its nature very tabular I saw no need for using an ORM. My use is very simple but maybe it will help. I currently only use SqueakDBX for retrieving this data. The data is inserted via a different program. Here is the method I use to get my data and insert it into a Matrix. loadOHLC "Loads the Open High Low Close (bid/ask) and hlavg, hlcavg columns from the database. Creates a OneWeekData (Matrix) object for the data." | con rows | con := self otogConnection. rows := (con execute: 'select startdate, bidopen, bidhigh, bidlow, bidclose, askopen, askhigh, asklow, askclose from ', self instrument, ' where (', self week asDbxString, ' < startdate) AND (startdate < ', self weekEnd asDbxString , ')') rows. ohlc := OneWeekData rows: (rows size) columns: 10. 1 to: rows size do: [:row || newRow | newRow := ((rows at: row) values). newRow := newRow copyWith: (((newRow at: 3) + (newRow at: 4) + (newRow at: 5)) / 3). ohlc atRow: row put: newRow ]. Maybe this real world example will help. As I said my usage is simple. SqueakDBX has worked very well for me. I simply wrote the sql statement I wanted executed with my columns ordered as I wanted for the rows retrieved. If I remember correctly each rows values are when passed the "values" message return an Array which is what I pass to my Matrix. If we aren't providing the answers desired. Please provide more information to direct us. Mariano has been very helpful for any of my questions. Jimmie
