Is there another way to view the profiling results of MiniProfiler (I'm specifically interested in EF5 version)?
Every tutorial that I've seen uses MiniProfiler.RenderIncludes(); but since my MVC app mostly returns JSON, that is not an option for me.
Is there a way to write results to file or something like that?
You can read and write results to just about anywhere by changing the MiniProfiler.Settings.Storage to a different IStorage implementation from the default (which stores to http cache). If you wanted to, this could store to and read from a file pretty easily (you would have to write your own custom implementation for that).
The files served by RenderIncludes are the html templates for displaying the results and the script to retrieve the results from the server and render them on the client (all found here). But you are by no means obliged to use this mechanism. If you want to write your own logic for retrieving and displaying results, you should base this off of the logic found in MiniProfilerHandler.GetSingleProfilerResult. This function roughly performs the following (putting in the siginificant steps for your purposes):
Gets Id of next results to retrieve (through MiniProfiler.Settings.Storage.List())
Retrieves the actual results (MiniProfiler.Settings.Storage.Load(id))
Marks the results as viewed so that they wont be retrieved again (MiniProfiler.Settings.Storage.SetViewed(user, id))
Converts these to ResultsJson and returns it
With access to MiniProfiler.Settings.Storage, you should be able to retrieve, serve and consume the profile results in any way that you want. And if you are interested in using the RenderIncludes engine but want to mess around with the html/js being served, you can provide your own custom ui templates that will replace the default behavior.

I'm using Google Data Studio to visualize results from various queries (from different tables within the same BigQuery-database).
For this reason, I created and use multiple data-sources-connectors. Each one of them has a SQL query included and makes use of an defined input parameter (which can be changed by report editors) - called "userid". It is the same id for all queries and resulting charts.
However, when I click "Manage URL parameters", I'm not allowed to use the same URL parameter for more than one data source (instead they are called ds0, ds1, ds2 etc - although they all end up being used as "userid").
If I add a data source under File - Report Settings, a new field "userid" appears, which I can alter - this will update ALL charts in the report with the very same userid (as expected). This works, but I do want to make use of an url which delivers an report with all updated queries depending on ONE userid.
Therefore, I guess I'm overseeing something - it should be possible to just use one query parameter to update the same "userid" for all queries in all data connectors? Or have I overlooked the possibility to fire multiple queries within one data source connector? Or is it expected to create a looong url full of redundant query parameters in this case?
I'm curious for your input!
Best regards :)
There does not seem to be any good solution for this.
For now the best workaround seems to be to just repeat the parameter multiple times -- it's ugly but it works. For example, use the URL parameter mapping screen to call the parameter u1, u2, etc., and then just pass all of them:
?params={"u1":"foo","u2":"foo"}
(URL encoded of course)
The ugliness is mostly for us developers: it violates our sense of DRY and clean code, and makes the URL much longer than it needs to be. However, most people don't care or know about the URL parameters so its irrelevant to them.
The bigger downside is that when the URL is distributed to clients (bookmarks, mobile apps), every time new data sources are added that require the same URL parameters, a new URL has to be distributed to clients for no good reason. A workaround for this is to build the URL dynamically via a simple redirector function.
This issue https://issuetracker.google.com/issues/180705297 is a feature request to implement this capability.
If you group the elements that you want to control with the same parameter (select and then shift G) then it will give you options to select the data source and the params box to apply to the group.
I've been searching for a day or 2 for an answer to this question, but I haven't found one yet. I've got an external application which is modifying a TSV file (adding data) periodically. I'm using the Basic Line Chart example to display the data and it looks really nice:
Now I want the data to update when the TSV file is updated. I want to be able to set an auto-refresh on the data where it pulls from the tsv file and repopulates the graph without refreshing the entire page.
I tried just wrapping up the current code in a function and calling setInterval on that function, but the data remains the same each time (maybe because it's cached?).
Ideally the solution to this would be a function which can be called to Update whenever I'd like (based on a user event, timer, whatever).
Any ideas, links, or suggestions for alternate ways to accomplish the same goal would be much appreciated!
As a bonus question: I understand D3 may not be the right choice for this sort of Psudo-Real-Time data display. Are there other packages which lend themselves to this sort of thing more? The app generating the data is a C# application (in case that ends up mattering).
Edit: As a supplementary explanation, imagine this example but with the data being read from a file: http://mbostock.github.com/d3/tutorial/bar-2.html
If you are executing an Ajax call to fetch the data from the server and you think caching is a problem, you can try busting the cache by setting the cache parameter in jquery's ajaxSetup to false anywhere in your code:
$.ajaxSetup({cache: false});
From the docs:
If set to false, it will force requested pages not to be cached by the
browser. Note: Setting cache to false will only work correctly with HEAD and
GET requests. It works by appending "_={timestamp}" to the GET parameters. The
parameter is not needed for other types of requests, except in IE8 when a
POST is made to a URL that has already been requested by a GET.

In my user interface I have a browser where I want to show a map, issuing an address like http://maps.google.com/maps?q= and then I indicate a URL where I have put a KML file with my data.
The problem is: is it possible to filter the data in the KML file in order to show only a subset of them ?
Basically you have two options:
Pass parameters to a service which generates your filtered KML on the fly.
Do it in JavaScript in your browser interface.
Based on your question, I am going to assume option one is out. For option two there are tons of examples on the web, but basically you need to parse the KML yourself and write JavaScript code to handle it however it needs to be done to achieve your filtering, you cannot pass the KML URL to google maps directly and achieve any of this behaviour.
Possibly useful example: http://www.gpsvisualizer.com/examples/google_folders.html
UPDATE
Based on conversation in the comments:
The only other thing I can think of is to create your own map page with the JavaScript to do what you want on it (like http://gpsvisualizer.com/examples/google_folders.html linked above) and then embedding it in your app instead of the google map. Essentially encapsulating the features you want. So instead of maps.google.com/maps?q= in your app you have myMapURL.com/MyMap?querystring which is your google maps wrapper with the desired filtering. Otherwise I think you are out of luck based on your current setup.
I'm making a pretty standard AJAXy (well, no XML actually) web page. The browser makes a bunch of API queries that return JSON to run the site. The problem is, I need to add to the API interface each time the page needs to do something new. The new API interface is usually little more than a database query followed by mapping the returned objects to JSON.
What I'd like to do is to get rid of all that server-side duplication and just have the page make database requests itself (using the model interface), but in a way that is safe (i.e. just read only ones). I think this would amount to an interface for constructing Q objects using JSON or something like that, and then send that up to the server, run the query, and return the results. Before I go making my own half-broken architecture for this, I'm wondering if this has already been done well. Also, is this even the best way to go about eliminating this duplication?
Thanks

I've been having a look at several MVC frameworks (like rails, merb, cakephp, codeignitier, and similars...)
All the samples I've seen are basically plain and simple CRUD pages, carrying all the infr needed in the querystring and the posted field values.
I've got a couple of apps made with some sort of framework built with classic asp.
This framework handles some CRUD stuff a little more complex than the examples I found.
Something like master-detail, filtering by example, paging, sorting and similars.
I have a controller class that it's just a finite state machine, that goes thru diferent states (like new, browse, filter, show, etc.), then performs the appropiate action depending on the event raised and finally retrieves the neede info to the calling page.
To achieve this I have several hidden inputs to keep the state of the web page (like current id, filter criterias, order criterias, previous state, previous event, well, you get the idea)
What do you think would be the finnest approach to achieve this kind of funcionality?
hidden inputs built in the view and used from the controller??? (I guess that would be the equivalent of what I'm doing right now in classi asp)

(added in response to tvanfosson)
basically, my question refers to the third category, the context-dependent setting (in respect to the other two categories I agree with you) the info I was storing in hidden fields to store them on the querystring, I guess that when you click on the "next page" you include everything you need to save in the querystring, right? so that piece of query string gets appended in each and every link that performns some kind of action...
I'm not sure, what are the advantages and disadvantages of using the querystring instead of hidden inputs???
I use different strategies depending on the character of the actual data. Things that are preferences, like default page size, I keep in a Preferences object (table) that is associated with the current logged in user and retrieve from there when needed.
Persistent settings associated with the current logon, like filter settings for a page, are stored in the user's session. Generally these are things that if a user sets them in the current session they should remain sticky. I think filter settings and visibility are like this. If I filter a list, navigate away from it to drill down into a particular item, then come back to the list, I want my filter settings to be reapplied -- so I make it part of the session.
Context-dependent settings -- like the current sort column or page number, are controlled using query parameters. Paging and sort controls (links) are built with the appropriate query parameters to "do the right thing" when clicked and pass any necessary query parameters to maintain or update the current context of the control. Using the query parameters allows you to use an HTTP GET, which is bookmarkable, rather than a POST. Using hidden form parameters makes it much harder for the user to save or enter a URL that takes them directly where they want to go. This is probably more useful for sorting than it is for paging, but the principle applies equally.
