I want to cache large HTML pages in an SQLite database as blobs, but the HTML pages may ofcourse contain lots of characters which will corrupt the SQL statement. I'm not too happy with performing search/replace to escape all characters messing up the SQL statement, and encoding the HTML to a format accepted by SQL seems like an expensiv...
Hi, I have a mysql database that holds content as a blob, for whatever reason those developers chose to use a blob is out of my control. Is it possible to convert the data to text and the data type to text? ...

I need a blob file field as part of a content type in plone. plone.app.blob's BlobField should provide this, but I can't find how to get a URL to download the file including the original filename (e.g. http://plone.site/plone/obj/orig-file-name.avi). Is there a way to do this using plone.app.blob? Alternately, there are a few pointers o...
I've been banging my head for a long time on this one I am doing imaging. So far I've binarized my images, meaning that from a grayscale image, every pixel under a certain value are dropped. This gives me only some regions out of the original image with a lot of "zero pixels" all around those regions. Next I've run length encoded my re...

QUESTION: Is it better to send large data blobs in JSON for simplicity, or send them as binary data over a separate connection? If the former, can you offer tips on how to optimize the JSON to minimize size? If the latter, is it worth it to logically connect the JSON data to the binary data using an identifier that appears in both,...

I looked and looked. Does anybody know how to track blobs from Aforge? I know they don't have it implemented but I would really need to use Aforge because of the rest of the code I'm using. I saw some reference to Kalman filtering but I need some implementation and not theories. tnx, v. ...
Hello, After looking at this tutorial on blobs: channel 9, I was thinking of using a blob container to save a bunch of tweets (storing the json of each tweet that is). Ideally I would like to create a blob reference for each hour of the day, and append new tweets to this blob as they come in. The issue is that the method UploadText(stri...
