I'm currently in process of correctly tagging all of my saved images, including the ones from Facebook and messenger. Does anyone know if there is a way to extract the correct create date from the filename or at least some naming convention so I can do more searching? :)
Here are some examples of filenames:
some examples of file names

I'm in need to read a large number of files from a permanent Dropbox webpage.
The reading part is fine, but I'm having troubles finding a way to list all the files contained within.
To be more precise, I would need something like
files = dir([url_to_Dropbox_directory,'*.file_extension']);
returning the names of all the files.
I've found an example in php, but nothing for MATLAB. Using dir was just an example, I'm looking for any solution to this problem.
How can I get the file list from a permanent Dropbox webpage?
You should use the Dropbox API where you can acces that data by a http request. "file-list-folder" is the specific endpoint that you are looking for.
Here is the documentation for it:
https://www.dropbox.com/developers/documentation/http/documentation#files-list_folder
In addition you could use the SDK for PHP (or others programming languages). I have used the SDK for JS and it's easy and works well.

Salesforce has two different UIs and in accordance with it, it has the possibility to store attached files differently.
Two files were uploaded via the classic UI and they are marked as 'attachments'. Other files were uploaded through the new UI and they are marked as 'files'.
I want to upload all of these files using REST API. I cannot find the proper documentation. Can somebody help me with this?
That's not 100% true. In SF Classic UI you were able to upload Files too. It's "just" about knowing the right API name of the table and you'll find lots of examples online.
Attachment and Document objects have exactly same API names, you can view their definitions in SOAP API definition or in REST API explorer (there was something which you can still see in screenshot in here, seems to be down now, maybe they're moving it to another area in documentation...)
The Files (incl. "Chatter Files") are stored in ContentDocument and ContentVersion object. The name is unexpected because long time ago SF purchased another company's product and it was called "Salesforce Content". In beginning it was bit of mess, now it's better integrated into whole platform but still some things lurk like File folders can be called Libraries sometimes in documentation but actual API name is ContentWorkspace. The entity relationship diagram can help a bit: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_erd_content.htm
ContentDocument is a header to which many places in SF link (imagine file wasting space on disk only once but being cross-linked from multiple records). It can have at least 1 version and if you need to update the document - you'd upload new version but all links in org wouldn't change, they'd still link to header.
So, how to use it?
REST API guide: https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_sobject_insert_update_blob.htm
or maybe Chatter API guide (you tagged it with chatter so chances are you already use it): https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/connect_resources_files.htm
some of my answers here might help (shameless plug). They're about upload and reading data too and one is even about data loader... but you might experiment with exporting files first, get familiar with structure before you load?

For my project I am using the StackExchange Data Dump that I found on https://archive.org/details/stackexchange.
To be able to do my work, I need to know what tags a user has used mostly (these are the tags you can find when looking on a user's profile page). However, when going to the Data Dump files, I noticed there is a file called User.xml so I was hoping to find these tags here but no I did not.
Is there a way so I can gather these tags for the Data Dumps? Or should I do it brainlessly by writing a small application that retrieves these tags by calling the StackExchange API with the UserId?
Thanks!
I have an rss reader app which works perfectly on some feeds, but on others it just displays text and no images.
Is it the feed which should be adjusted to publish images or Im sure it is something with the way I read the stream.
Why does it work for some streams(shows entire posts, images, videos etc. from e.g. blogspot rss feeds) but not for other rss feeds?
I have read that the stream itself can be set to publish different content amounts.
How can I parse the feed so that all feeds will work correctly?
It's very likely that it's due to the feed themselves... and not to the reader app.
Feed publisher can decide whether they want to include all or parts only of their content in their feeds (RSS or Atom).
Then, even if they publish all the content, they may decide to publish it as raw text (just the text content) or full XHTML, which would allow the inclusion of images.
Unfortunately, there is little that you can do, except maybe ask the developer of your app to allow to show the original site/page and not just the feed entries.
Ok, so what are the differences between the feeds that work and the feeds that don't? What assumptions do you make about the RSS content, and in what situations are those assumptions not satisfied? When you run the code in the debugger, what do you see when you encounter a feed where images don't work? Also, what code? ;)
Is there an Iphone SDK API to search resource files?
I have a set of html file resources that I'd like the user to be able to search in, but I want to avoid reading the files into memory and searching them one by one.
Is there any API that can help me do this?
No, you'll have to read the files in to search them. There's nothing like "Spotlight" on the phone.
I would suggest you using SQLite FTS3 extension for full text search through your documents. It has quite good capabilities for it. But you will need to strip HTML tags first so it can index only your text and don't bother with tags
