Resize a image stored in a Oracle's BLOB Field
by Juan Javier Carrera Obrero 27 Nov '01

27 Nov '01

Hello, Thanks, I have displayed the images which them was stored in a Oracle's BLOB field, with: <dtml-call expr="RESPONSE.setHeader('content-type','image/jpeg')"> <dtml-in SQLMethod_with_a_Only_Row> <dtml-var expr="BLOB_FIELD.read()"> </dtml-in> However, I would like to resize this image. I can not do it with the "height" and "width" attributes, because the image is obtained from a Oracle's BLOB field, and no from image object (i.e.: I can not use <dtml-var "ImageObject.tag(border='5', align='left')">). How can I do it ? Thanks again !

Re: [Zope-dev] Acquisition wishlist :-)

As a side effect to turn off acquisition, you defined the attribute. This will not play well with inheritance: You will not only prevent acquisition of "index_html" but also prevent inheritance of it (which may be really necessary in some contexts). Dieter

Zope Filesystem
by Christian Robottom Reis 15 May '00

15 May '00

Sorry if this is brought up excessively. I'm wondering if we have any ongoing project to provide Zope with a filesystem driver for Linux. I understand there's the question of object semantics being mapped onto files, but AFAICS as soon as that's decided it's a relatively easy task, no? There's already an FTP interface for Zope, and IIRC there _is_ something like a ftpfs either developed and dead or moving along slowly. This perhaps could serve as a temporary kludge? The main vantages are freedom from the Web Editing interface, which isn't the greatest - at least till we get a vi-binded textarea on a browser, which IMHO isn't coming very soon, and freedom to use whatever revision control tools we'd like. I understand objects themselves wouldn't be supported, but since DTML documents are plain text, they at least would work fine, excluding attribute/permission trouble. This is not unsolvabale, AFAICS. [Another idea would be a plugin or module for editors - vim comes to mind - which allows you to post the data to a webserver on a write. This is more complex and is a 1-per-client thing, so I'm not sure it's that interesting]. Comments?

Just some basic load tests using ab against a specific set of URLs with and without the patch would provide some not-very-scientific-but-still-useful feel for how big the win is...

I don't know Perl at all so I'm probably not going to investigate this, unless the algorithm is pretty simple. Also the morphological dictionary looks like it can get big, I'd like to use a more advanced data structure than just a flat file dictionary; the splitter is used very often, and constantly refering to a flat file would be horrible. I was probably going to use their dictionary to start with. > b) What algorithm do you use in your searching of text ? Is it just a > simple frequency tally ? I'm not sure what a simple frequency tally is. A text index is a mapping from a word id to a sequence of (documentid, score) tuples. o The word id (which is an integer) is mapped to a word by the Lexicon, o the document_id (which is also an integer) is mapped to a 'document' (and Zope object really) by the Catalog. o The score is the number of times the word that maps to the word id was found in the document that maps to the document id. Text indexes do not make any assumption about what a 'word' is, or how it came to be a word. All language specific information, such as how to split a document in a certain language into words, is handled by the Lexicon. The splitting of a 'document' into words is done by the Splitter object provided by the Lexicon. The Splitter object is what would need to implement the morphological analysis algorithm for whatever language you are going for. In the case of english, this is very simple and involves splitting a document up at whitespaces. The algorithm for Chinese or Japanese is much harder, as you're aware. -Michel

socket newbie question
by Toby Dickenson 01 Apr '00

01 Apr '00

In select_trigger.py, the non-posix version of the trigger class binds a socket to a port on the address 127.9.9.9. Can anyone explain the significance of using this address, rather than 127.0.0.1 ? Thanks, Toby Dickenson tdickenson(a)geminidataloggers.com

Hey, ZEO will allow several Zope installations to work as one distributed Zope system. In other words ,this accomplishes what you describe invisibly.

Zope Inter-Object Communication Protocol
by Jason Spisak 31 Mar '00

31 Mar '00

Zopists, Is there currently any effort to develop a way for a Zope object from one ZODB to communicate with another object from another ZODB? JNI like stuff, or other what-cha-ma-call-its... All my best, -- Jason Spisak 444(a)hiretechs.com
