Re: [Pharo-project] happy new year plus cogdroid news

by Schwab,Wilhelm K

Does an Archos 43 count as an Android device? I bought it with plans that fell flat (the target moved, and the OS was a little disappointing). That said, I have it and can help with testing. I do not have a data plan for it, so my default usage is to copy packages to it via USB. It is hard to imagine developing on it, but I'm willing to be pleasantly surprised, and it would be nice to be able to deploy Pharo apps on hand-held devices.

RFC1952 is short and clear enough that extracts from probably don't need to be included it like the last one I did. -------------8<----snip--------------- This class defines magic numbers taken from the RFC1952 GZIP file format specification version 4.3 (1996) [1]. A class imports these constants as 'class variables' by including the following in its class definition: poolDictionaries: 'GZipConstants' A method on the class side initialises the values. [1] http://www.ietf.org/rfc/rfc1952.txt (Section 2.3.1 Member header and trailer) -------------8<----snip--------------- As an aside the following in [GzipConstants class >> initialize] does not match the specification for bit 5 as "reserved". GZipEncryptFlag := 16r20. "Archive is encrypted" I did find it defined here [2] & [3] however the FAQ [4] specifically says encryption is NOT part of the standard. This constant is only used in [GzipReadStream >> on:from:to] as... (flags anyMask: GZipEncryptFlag) ifTrue:[^self error:'Cannot decompress encrypted stream']. So perhaps its okay to leave but maybe some slight benefit from amending the text as follows.. GZipEncryptFlag := 16r20. "Archive is encrypted. Not supported. Not part of the standard." ifTrue:[^self error:'Cannot decompress encrypted stream. Encryption is not part of RFC1952']. It is a better presentation to a user if you can indicate that it is someone else's fault that their decompress failed, and not Pharo.

I am not sure the image size is really a problem on a tablet ? lot of games - angry birds game (free on android market ) for example- are about 30MB if I m right, and the download from the market is no problem. Are you talking of the splitting of the image because of resource size restrictions , as mentioned by andreas in his first post ? (BTW a small image would be good too) > I think Android takes care of it itself: once an application is > invisible it is suspended automatically. Or did you notice any > performance degradation? I clearly had the feeling that the battery is going down faster when I use Pharo perhaps because not all Smalltalk processes are sleepng and so the vm never sleep ? The UI morphic process make pauses of 20 ms when there is not event , I don't know for others processes (Timer event loop, Input events process). I have to investigate >> - interface to android content providers (audio, video, calendar data >> etc) > > Working on it ;) In fact, there is a (partial) interface to the intent > system, so a home screen shortcuts can be added to start CogDroid with > given image and startup arguments.

Cool, if the clipboard vm primitives are ok, the System Clipboard class should work ?. Regards, Alain

Re: [Pharo-project] Pharo by Example

by Serge Stinckwich

Yes for the french edition of Pharo by example, we have done a special one click image. We have also done modifications in the book. I guess these modifications can be done also on the english version.

by Guillermo Polito

Hi! I'm willing to announce the second beta release of Phoseydon, part of the DBXTalk project, supported by ESUG :). It's main new feature is a simple internal dsl to generate entities, so you can create applications from something like: personEntity := application entityNamed: #Person. personEntity hasString: #nickname; hasInteger: #age; hasBoolean: #isProgrammer. petEntity := application entityNamed: #Pet. petEntity hasString: #nickname. personEntity hasMany: #Pet as: #pets. petEntity hasOne: #Person as: #owner. Also, a little manual is already written in: http://dbxtalk.smallworks.com.ar/pier/Documentation For download: http://dbxtalk.smallworks.com.ar/pier/Download Issues, mails, questions: http://dbxtalk.smallworks.com.ar/pier/Support Cheers, the DBXTalk Team
