Rearrange inventory of specific game in steam? is it possible or not?
I checked steamworks and steam api for some information but there is nothing about it, only getting items not changing positions.
There is not an API for this functionality. There is, however, a pull request to the (TF2 centric) SteamBot application that adds this functionality to that project. One thing to be aware of, though, is that this pull request is 7 months old and hasn't been merged in by the project developers. In that time, Valve has made changes that required SteamBot changes due to underlying Steam network changes. This request may or may not work any more. It may give you an idea of what needs to be done.

I started modifying/developing Rally apps about a week ago using the existing Rally apps provided on the Github repository so far. However, for one of my final tasks I've been asked to recreate a tailored Defect Trend Report App and unfortunately, the source code is not available for the App. I tried to start from scratch but I've ran into numerous errors and am a bit overwhelmed.
I was wondering if anyone had the src code for the app or knew of a way to extract the src code from the existing app. Of course if there is custom code that an individual has worked on that could also help me progress in this process and wouldn't mind sharing it, that'd also help a ton.
I saw that there were a few snippets that could be used from the Hackathon repo, but they're not quite on the mark of what I want to do with the app. I'm just trying to have the existing app filtered by delivery versions (currently filtered by iteration/release).
All help is greatly appreciated.
Thanks fellas!
There is an example of a 'bare metal' chart app in the App SDK 2.0 docs. It should give you the basics on how to do a chart.To get to it, go to the help pages (click on avatar in top right corner) and search for "Rally App SDK"
After that, you need to work out how to select defects from the various releases and do a count of each. There are two ways to do this:
Get all defects in the project you are in (don't forget whether you need to scope down to child projects too) and then do something like _.uniq() on the release field to find the list of releases (or do another request to get all the releases into a different store and use that for names and a count).
Get the releases and then for each release request the related defects.
If you do ask for child projects, you will need to handle all the scenarios of different releases for different projects - can get complicated!
#1 is effectively one big fetch, #2 may be many smaller ones.
You may want to decide whether to count all defects, sum the estimates, ignore those not finished, etc., etc.
There appear to be two lines of APIs for adding, authenticating and aggregating sites. Depending upon which version of the Documentation/SDK set your rep started you off on, or where in the SDK Guide you started implementing from determines where you start.
Path #1 starts at
ContentServiceTraversal which allows for the retrieval of all ContentServiceInfo (by container type (such as BANK)
ItemManagementService is used to add these items
Refresh is done through RefreshService (most API not containing the word Site)
Path #2 starts at
SiteTranversalService which allows for the retrieval of all SiteInfo (no apparent support for Container Type filter)
SiteAccountManagementService is used to add these items
Refresh is done through Refreshservice (all API containing the word Site).
From the best that I can tell the aforementioned API have a lot of functionality duplication. I have noticed certain API that exist on one branch and not the other but usually they are minor changes (e.g. things you are able to filter by).
I started off with ContentServiceInfo because the documentation and samples that our rep initially gave us started there. Additionally this API started off by providing greater granularity (e.g. simply being able to filter by Container type since we were pretty much only interested in Banks and Processor sites (which I do not believe you guys support)).
My questions are:
Do the two branches of API do the exact same thing?
Do they mostly behave the same way?
Do they back-end to the exact same
System
Data store
Scraper?
Is one line of API supposed to be deprecated sooner in the future than another?
Does one line of API have more future in terms of actually adding new or augmenting existing functionality?
Site-level addition has been introduced through Yodlee APIs to overcome the fact that though a user had bank,creditcard,loan,rewards account at the same end site, user had to provide credentials for each of these containers. Site level addition APIs try to add all these containers with only 1 set of credentials. That's the only difference between container based addition and site based addition.
As to answer your questions:
Do the two branches of API do the exact same thing?
Do they mostly behave the same way?
If you mean the aggregation functionality, Yes.Except for the fact that Site level adds/refreshes all the container(bank,creditcard,loan,rewards) and Container level can add/refresh only one container per API call, all the other behavior will remain the same.
Do they back-end to the exact same
System
Data store
Scraper?
If you are referring to the Yodlee data gathering components, Yes.
Is one line of API supposed to be deprecated sooner in the future than another?
No.Both these sets of APIs cater to different needs. If you are a company who solely rely on Creditcard data, using site level addition will be overkill as it will take longer time for the aggregation and it makes more sense to use container based addition. There is also the factor of backward compatibility, which rules out deprecation of APIs.
I'm building my first REST API (at least trying) for a personal project.
In this project there are resources called players which hold can be in a team. According to REST API design rulebook a resource should be made either to be a document or a store and one should keeps these roles as segregated as possible.
Yet I would like to append some metadata to the team resource, eg the date the team was founded. Is it okay then for GET /teams/atlanta to return this metadata (making it a document) alongside the list of players in the team (making it a store).
Is this a good idea? If so why? If not why not and how to solve this better?
I know there are no rules to developing a REST API, but there are good practices and I would like to adhere to those. Please also not that this is really my first REST API so pardon my ignorance if there is any.
I would recommend having GET /teams/atlanta return just the information about the team, such as the founding date that you mention, and then having GET /teams/atlanta/players return the list of players for that team. These distinctions become more important when you are presenting an API that uses HTTP methods other than GET.
For example, if you wanted to add a player to a team - this would be a lot easier if you could just POST a player object to /teams/atlanta/players than if you had to PUT the whole team object to /teams/atlanta every time you wanted to add one individual player.
If your API only allows retrieval of data, and if it is for a specific client application, there is an argument for combining all the team data into one object to save the client having to make additional requests for the data, but bear in mind that it is less flexible.
Your application may want to display a list of teams by calling GET /teams but you probably wouldn't want all of the player information included in each object in the list as this is quite a lot of data, but if GET /teams/atlanta returns player information then it would be inconsistent not to include it in the list version too.
I would personally favour splitting up the resources as I've suggested, and live with the fact the client may need to make an extra request or two.
I have 2 1/2 years experience of VB.Net, mostly self taught, so please bear with me if I seem rather noobish still and do not know some of the basics. I would recommend you grab a cup of tea before starting on this, as it appears to have got quite long...
I currently have a rather large application (VB.Net website) of over 15000 lines of code at the last count. It does not do retail or anything particularly complex like that - it is literally just a wholesale viewing website with admin frontend, catalogue / catalogue management system and pageview system.
I don't really know much about how .Net applications work in the background - whether they are all loaded on the same thread or if each has its own thread... I just know how to code them, or at least like to think I do... :-)
Basically my application is set up as follows:
There are two different areas - the customer area and the administration frontend.
The main part of the customer frontend is the Catalogue. The MasterPage will load a list of products but that's all, and this is common to all the customer frontend pages.
I tend to work on only one or several parts of the application at a time before uploading the changes. So, for example, I may alter the hierarchy of the Catalogue and change the Catalogue page to match the hierarchy change whilst leaving everything else alone.
The pageview database is getting really quite large and so it is getting rather slow when the application is first requested due to the way it works.
The application timeout is set to 5 minutes - don't know how to change it, I have even tried asking this question on here and seem to remember the solution was quite complex and I was recommended not to change it, but if a customer requests the application 5 minutes after the last page view then it will reload the application from scratch. This means there is a very slow page load whenever it exceeds 5 minutes of inactivity.
I am not sure if this needs consideration to determine how best to split the application up, if at all, but each part of the catalogue system is set up as follows:
A Manager class at the top level, which is used by the admin frontend to add, edit and remove items of the specified type and the customer frontend to retrieve a list of items of the specified type. For example the "RangeManager" will contain a list of product "Ranges" and will be used to interact with these from the customer frontend.
An Item class, for example Range, which contains a list of Attributes. For example Name, Description, Visible, Created, CreatedBy and so on. The form for adding / editing loops through these to display relevant controls for the administrator. For example a Checkbox for BooleanAttribute.
An Attribute class, which can be of type StringAttribute, BooleanAttribute, IntegerAttribute and so on. There are also custom Attributes (not just datatypes) such as RangeAttribute, UserAttribute and so on. These are given a data field which is used to get a piece of data specific to the item it is contained in when it is first requested. Basically the Item is given a DataRow which is stored and accessed by Attributes only when they are first requested.
When one item is requested from a specific manager is requested, the manager will loop through all the items in the database and create a new instance of the item class. For example when a Range is requested from the RangeManager, the RangeManager will loop through all of the DataRows in the Ranges table and create a new instance of Range for each one. As stated above it simply creates a new instance with the DataRow, rather than loading all the data into it there and then. The Attributes themselves fetch the relevant data from the DataRow as and when they're first requested.
It just seems a tad stupid, in my mind, to recompile and upload the entire application every time I fix a minor bug or a spelling mistake for a word which is in the code behind (for example if I set the text of a Label dynamically). A fix / change to the Catalogue page, the way it is now, may mean a customer trying to view the Contact page, which is in no way related to the Catalogue page apart from by having the same MasterPage, cannot do so because the DLL is being uploaded.
Basically my question is, given my current situation, how would people suggest I change the architecture of the application by way of splitting it into multiple applications? I mean would it be just customer / admin, or customer / admin and pageviews, or some other way? Or not at all? Are there any other alternatives which I have not mentioned here? Could web services come in handy here? Like split the catalogue itself into a different application and just have the masterpage for all the other pages use a web service to get the names of the products to list on the left hand side? Am I just way WAY over-complicating things? Judging by the length of this question I probably am, and it wouldn't be the first time... I have tried to keep it short, but I always fail... :-)
Many thanks in advance, and sorry if I have just totally confused you!

15000 LOC is not really all that big.
It sounds like you are not pre-compiling your site for publishing. You may want to read this: http://msdn.microsoft.com/en-us/library/1y1404zt(v=vs.80).aspx
Recompiling and uploading the application is the best way to do it. If all you are changing is your markup, that can be uploaded individually (e.g. changing some html layout in an aspx page).
I don't know what you mean here by application timeout, but if your app domain recycles every 5 minutes, then that doesn't seem right at all. You should look into this.
Also, if you find yourself working on various different parts of the site (i.e. many different changes), but need to deploy only some items in isolation, then you should look into how you are using your source control tools (you are using one, aren't you?). Look into something like GIT and branching/merging.
Start by reading:
Application Architecture Guide
What would be best practice for the following situation. I have an ecommerce store that pulls down inventory levels from a distributor. Should the site, for everytime a user loads a product detail page use the third party API for the most up to date data? Or, should the site using third party APIs and then store that data for a certain amount of time in it's own system and update it periodically?
To me it seems obvious that it should be updated everytime the product detail page is loaded but what about high traffic ecommerce stores? Are completely different solutions used for that case?
In this case I would definitely cache the results from the distributor's site for some period of time, rather than hitting them every time you get a request. However, I would not simply use a blanket 5 minute or 30 minute timeout for all cache entries. Instead, I would use some heuristics. If possible, for instance if your application is written in a language like Python, you could attach a simple script to every product which implements the timeout.
This way, if it is an item that is requested infrequently, or one that has a large amount in stock, you could cache for a longer time.
if product.popularityrating > 8 or product.lastqtyinstock < 20:
cache.expire(productnum)
distributor.checkstock(productnum)
This gives you flexibility that you can call on if you need it. Initially, you can set all the rules to something like:
cache.expireover("3m",productnum)
distributor.checkstock(productnum)
In actual fact, the script would probably not include the checkstock function call because that would be in the main app, but it is included here for context. If python seems too heavyweiaght to include just for this small amount of flexibilty, then have a look at TCL which was specifically designed for this type of job. Both can be embedded easily in C, C++, C# and Java applications.
Actually, there is another solution. Your distributor keeps the product catalog on their servers and gives you access to it via Open Catalog Interface. When a user wants to make an order he gets redirected in-place to the distributor's catalog, chooses items then transfers selection back to your shop.
It is widely used in SRM (Supplier Relationship Management) branch.
It depends on many factors: the traffic to your site, how often the inventory levels change, the business impact of displaing outdated data, how often the supplers allow you to call their API, their API's SLA in terms of availability and performance, and so on.
Once you have these answers, there are of course many possibilities here. For example, for a low-traffic site where getting the inventory right is important, you may want to call the 3rd-party API on every call, but revert to some alternative behavior (such as using cached data) if the API does not respond within a certain timeout.
Sometimes, well-designed APIs will include hints as to the validity period of the data. For example, some REST-over-HTTP APIs support various HTTP Cache control headers that can be used to specify a validity period, or to only retrieve data if it has changed since last request.
