I need to retrieve the whole OneDrive file list of the user, to sync it to my local database.
Is there a good solution?
I don't want to recursively traverse the whole file tree, which is very inefficient...
At first I thought I could do it with the /search&q=* endpoint, but they return max 500 results with no pagination option.
Unfortunately recursion is the only way you can accomplish this at the moment. Hopefully this is something that will be improved in the future.

I have a simple query regarding the Wikimedia/Wikipedia API.
I have to fetch the changes made from a list of "revids". I am able to fetch the XML content for a batch of "revids", but I failed to extract only the changed text.
Does API provide any way to extract only the changed sentences? If not any external script/module that can do this job?
Query to fetch the revision details: https://en.wikipedia.org/w/api.php?action=query&prop=info|revisions&rvprop=user|userid|ids|tags|comment|content&format=jsonfm&revids=1228415
I would appreciate any suggestions/solutions that could solve this issue!
(Currently, I am using the Wikitools python module to make the queries)
You can get the diff between the old and new text with action=compare, but it segments text by wikitext lines, not sentences, isn't meant to be machine-readable, and is generally not that helpful. Since you are using Python, the client-side library deltas will probably work better for you.
This is an open ended question. I have noob understanding of databases but willing to learn whatever is required. Though I believe my problem could be done without learning a lot.
So, here goes the question:
I have large amount of files getting generated in mt projects(depending on the builds) and I need to archive them and also need to reproduce them according to buildNumber if requested by users. I don't expect these requests to be a lot. May be 1-2 requests a day.
For eg: 16GB data per build every week. Most of the files in weekly builds are duplicate. And I don't want to archive them again and again. I prefer to store them only once. There is one caveat that it can happen that the files relative location can change, even though content hasn't changed.
My approach is as follow: Create a hash from each file. Create the key-value pair as fileHash-actual file and store it. Store this information in some kind of manifest file for each build. So, I should be able to create the builds back with correct files/paths etc.
Can it ever happen that 2 different files will ever have the same hash? Can some database help to do it efficiently? I am currently thinking of dumping all files in one folder.
Thanks
I'm working on an iOS app that creates "location sets" where each row contains a location name and a GeoPoint, and each set has its own name. Each of these sets are stored in an object inside our program (all belonging to the same class). Now we want to give users the capability to create sets and upload them to a database, allowing other users to access and download them to their device.
I've been looking in to back-end solutions for work like this, but pretty much everything I've found so far focuses on relational databases and adding and deleting rows and using SQL-like language to retrieve them. Is there a way to store these objects just as objects (and not unpack the info inside to tables), and then retrieve them? It feels like that would be a much simpler way of going about this.
I'm an absolute beginner when it comes to databases, so forgive me if there's info missing here that you would need to help me out. I'll make sure to keep checking back in case someone asks for more info.
Thanks!
Coredata might be useful for you as its based upon the entity. So you can play multiple things around it by using queries (predicates).
But if you just want to save and retrieve back, then as a simplest solution I would suggest to create array/dictionary with entity data, save that into NSUserDefaults so you can retrieve back same while re-launching the app.

I ended up using Parse's mobile back-end service. That was the type of service I was looking for. I've found other similar services since then, like Applilcasa and StackMob, but we're pretty happy with Parse so far.
I'm building a Sharepoint 2010 export tool for back up reasons (a bit like the filemanager from Metavis).
When downloading a file to local disk I need to back up the metadata associated with the document. Which I will store in a csv-file. My first approach was to iterate all listItem.fieldvalues, but that doesn't really work because some fieldvalues are complex types, which would needlessly complicate the backup file. Some values even have line endings, for example "MetaInfo". Furthermore not all values are needed to restore the content when that might be necessary.
So my idea is to only get the values from the Fieldvalues collection which are needed to do a functional restore, supplemented with all the user added metadata.
To do this I want to check all fieldvalues against an exclusion list to see if it is present. If it is present don't back up. If it is it is either user generated metadata or a value I need like for instance "author", "created".
So my question is, does anyone know of a list of all fieldvalues keys?
Or is there a better approach to my problem?
Thanks
Update: Well, as I was iterating through the FieldValues collection any way. It was easy to do a dump of all the values to a CSV. Running it once was enough to get all the values. Now all I need to write is an xml file for configuration. This leaves the question: is there a better way of doing this?
Filter the list fields by writing following code
using System;
using Microsoft.SharePoint.Client;
clientContext.Load(
listItems,
items => items
.Include(
item => item["Title"],
item => item["Category"],
item => item["Estimate"]));

You can create an view with all fields, get the view using sharepoint object model and and get its column name from collection and filter them as per your requirement.
I have finished the application. As I wrote in my update I have made a list of all fieldValues by exporting them to a CSV file. After that I made a configuration-file with a boolean 'Backup'. This makes it possible to control which values are to be used when a backup is made.
I retrospect I think a configuration file was not needed. The values used when backing up are so much part of the whole workings of the program that a configuration file gives an administrator or casual future developer the impression that a simple reconfiguring will fulfill there needs.
I can now see that if the program needs to change due to new requirements the code has to be changed anyway. So even though setting a value to 'True' will change the output. Some other code has to be written as well. If I were to write it again I would probably use constants. This makes it all less dynamic, but still fulfill the needs of the program.
(BTW a list of all the names off the standard fieldValues would have been nice to start with. I would publish it here, but I don't have access to the file anymore, because I switched jobs recently.)
I'm looking for the best solution to store the ettings for a website, like the limit of posts for users, limit of users online, ranks, min. number of posts to be able to do something.
Like here, if you're new you can't thumbs up/down a post, or whatever, so how would you store all of these?
I thought of creating a table with constants in mysql but i think it's not the best solution to add a new mysql query on every page refresh.
Why not? After all, MySQL can handle a large number of requests and I've seen much more complex queries than checking access rights. A MySQL query is a query to a file just like checking an INI file, but optimized. I'm guessing that if you don't expect a huge amount of traffic, you'll be fine with a database.
Here it's a matter of preference. I prefer to do this in MySQL because I don't like to parse files and find querying a database easier. Also, editing rows is easier than changing values in a text file.
I'd say your first thought was spot-on. Put constants into a database.
