Vision API topicality and score always the same - google-cloud-platform

When I look in label_annotions of the Google Vision API, the "score" and "topicality" field values are always the same. This is also for example the case here. According to this reference topicality refers to "the relevancy of the ICA (Image Content Annotation) label to the image" whereas score has replaced "confidence". Though it's now not so clear to me what "score" actually means.
Are these supposed to be always the same? What does that mean?

As you well mentioned, these "score" and "topicality" fields always display the same value. Based on my understanding, this is an existing bug on the Vision API functionality that needs to be fixed in a future release. I recommend you to take a look on this ticket that has been created to review this issue, as well as the Release Notes documentation of Vision API to keep the track of the new functionalities added to the service.

How to get all the versions of a particular FHIR resource in AWS FHIR store?

Is there a way to get the list of all the versions of a specific resource created in FHIR store. I have used the following call,
<FHIR_URL>/<resource-type>/<resource-id>/_history
but its not returning response
If I add version to this url:
<FHIR_URL>/<resource-type>/<resource-id>/_history/<version>
then it only shows that particular version of the resource, but all the versions of a specific resource are required, is there a way to get this?
When in doubt, I always try the reference-implementations.
(all GET requests below)
http://wildfhir4.aegis.net/fhir4-0-1/Patient/example/_history
https://vonk.fire.ly/R4/Patient/pat1/_history
http://hapi.fhir.org/baseR4/Patient/616330/_history?_count=50
I got each systems Patient-Fhir-Logical-Id ("example", "pat1", "616330") by using the search function, and picking a random Patient. The Search function is as simple as /Patient/? and no query string values.
While always subject to change and "re doing the seed data", the aegis example above (today) is returning multiple rows of history for a single patient.
If AWS does not work "mostly the same" as the 3 reference implementations, I would submit a bug report.
But based on your examples, it seems to fall in line with the reference implementation examples above and the HL7 documentation below.

Did Google recently change UI to grant public access to bucket objects in Google Cloud Platform?

Ok, I've been using Google Cloud Platform for some video files
that are are viewable from a few web pages I built. I started this two or three years ago, and I have loved it.
But, now it appears they broke it, without warning/telling us.
So, in the platform's console, yesterday (for first time since a month or two ago), I uploaded another video...that part went fine. But, when it came time to click on the checkbox to grant public access, the checkbox is now GONE. (The only part of the UI that looks NEW,
is the column labeled 'public access'. Instead of just a check-box to toggle on or off, now there's a yellow-triangle and an oval-shaped symbol. Once or twice, I was able to get a popup to appear saying 'edit permission', but that quickly led into the weeds.)
After half an hour or so, I finally thought to call platform support, and explained my problem to a guy (with just enough Australian accent to cause me to have to ask for repeats quite a bit...sigh).
So, they logged me a case# and I suggested I was headed to bed, and asked that we now use email (rather than the phone) to continue. Just before bed, I got the case#, and a query about whether it was ok for them to 'change my console'. I replied to the email, saying yes, and went to bed.)
So that was last nite. This morning, re-reading their email, it seems to say that it could be 3 or 4 days, before a more technical person will contact me.
Some re-reading their platform-console docs, I'm now GUESSING that maybe they just nuked the public-access checkbox, and that now I'm supposed to spend hours (days?) taking a short-course on IAM-permmissions, and learn some new long-winded method.
(This whole mess could have been avoided, if they'd just emailed us an informational warning of this UI-change, with some new 5-step short list or tutorial of how to learn to use their 'new, much more complicated,
way to specify public-access'. From where I sit, this change is equivalent to Microsoft saying 'instead of that checkbox, you'll need to learn to make registry edits...see our platform docs on how to do that.)
Right now, I have more than half-a-mind, to seriously consider bailing out of Google's cloud storage, and consider switching to one of the others. But, I'm not quite ready yet, to make that jump (from the frying-pan into the fire?). :^)
Anyone else been down this road? What meeting did I miss? Is there a quicker way out of my dilemma, than just waiting for Google-support to get back to me?
It looks like the change you mention was introduced on July 18th. I’m not sure why, but judging by the change description, it looks like it is aimed to avoid accidentally making sensitive information public: “Objects can no longer be made public through one-click actions”.
You can find the procedure to make a single object public here. It can be achieved through the Console and won't take you more than a few minutes. Once the object is shared publicly, you can use the icon in the “public access” column to get the URL for the object.
You can also make all the content of a bucket public using a similar approach.
When you upload your objects into a bucket, you can upload with ACL as publicRead
and all your objects will have public URL.
public async Task UploadObjectAsync(string bucketName, string objectName, Stream source, string contentType = "image/jpeg")
{
var storage = StorageClient.Create();
await storage.UploadObjectAsync(bucketName, objectName, contentType, source, new UploadObjectOptions()
{
PredefinedAcl = PredefinedObjectAcl.PublicRead
});
}
As I suspected. (I still wonder if they even considered sending an email to each registered/existing customer.)
Ok, yes, (finally, after some practices), this solves it! Thx for those two answers.
(But in my view, their UI-change is still a work-in-progress) So, I have a SUGGESTION for ya, Google. Once one is into the permissions-edit-dialog, and remembers to do an 'add', there's are the 3 fields. The first and third are fine...drop-downs with choices. But that middle entry needs work...how about doing something like an auto-guess-ahead...initialize the field to a suggested value of 'allUsers', so we don't have to remember what to type and how to spell it, or something along those lines.
EDIT: [Actually, it ought to be possible to make that field a drop-down-list choice, with 'allUsers' as one suggested value, and a second value as a text-entry (for specific user-names, etc).]
Unfortunately, 8 Ball Pool it is not possible to list files Google Hangouts without access to the Omegle bucket that contains them. This is due to the current design of the library, which requires that the bucket is loaded before listing its files.

Correct REST API URL format for related objects

I'm designing a REST API where, amongst others, there are two objects.
Journey
Report
For each Journey there are many Reports enroute, and each Report has exactly one associated Journey.
A user might create a Journey using the API as follows...
POST /journey/
Then retrieve the details...
GET /journey/1226/
The first question is, if a user wanted to post an Report to their Journey, which is the 'correct' URL structure that the API should impose? This seems intuitive to me...
POST /journey/1226/report/
...or is this the case...
POST /report/
...whereby in the latter, the Journey ID is passed in the request body somewhere?
The second question is, how might one go about implementing the first case in a tool such as the Django REST framework?
Thanks!
The URL/URI structure is almost completely irrelevant. It is nice to be able to read it, or easily change or even guess it, but that is it. There is no "requirement" official or unwritten how they should look like.
The point is however, that you supply the URIs to your clients in your responses. Each GET will get you a representation that contains links to the next "states" that your client can reach. This means the server has full control over URI structure, the client usually has to only know the "start" or "homepage" URI, and that's it.
Here is an article which discusses this question, has some good points: http://www.ben-morris.com/hackable-uris-may-look-nice-but-they-dont-have-much-to-do-with-rest-and-hateoas/
Pass for the second question :) I didn't use that particular framework.

RESTful API and Foreign key handling for POSTs and PUTs

I'm helping develop a new API for an existing database.
I'm using Python 2.7.3, Django 1.5 and the django-rest-framework 2.2.4 with PostgreSQL 9.1
I need/want good documentation for the API, but I'm shorthanded and I hate writing/maintaining documentation (one of my many flaws).
I need to allow consumers of the API to add new "POS" (points of sale) locations. In the Postgres database, there is a foreign key from pos to pos_location_type. So, here is a simplified table structure.
pos_location_type(
id serial,
description text not null
);
pos(
id serial,
pos_name text not null,
pos_location_type_id int not null references pos_location_type(id)
);
So, to allow them to POST a new pos, they will need to give me a "pos_name" an a valid pos_location_type. So, I've been reading about this stuff all weekend. Lots of debates out there.
How is my API consumers going to know what a pos_location_type is? Or what value to pass here?
It seems like I need to tell them where to get a valid list of pos_locations. Something like:
GET /pos_location/
As a quick note, examples of pos_location_type descriptions might be: ('school', 'park', 'office').
I really like the "Browseability" of of the Django REST Framework, but, it doesn't seem to address this type of thing, and I actually had a very nice chat on IRC with Tom Christie earlier today, and he didn't really have an answer on what to do here (or maybe I never made my question clear).
I've looked at Swagger, and that's a very cool/interesting project, but take a look at their "pet" resource on their demo here. Notice it is pretty similar to what I need to do. To add a new pet, you need to pass a category, which they define as class Category(id: long, name: string). How is the consumer suppose to know what to pass here? What's a valid id? or name?
In Django rest framework, I can define/override what is returned in the OPTION call. I guess I could come up with my own little "system" here and return some information like:
pos-location-url: '/pos_location/'
in the generic form, it would be: {resource}-url: '/path/to/resource_list'
and that would sort of work for the documentation side, but I'm not sure if that's really a nice solution programmatically. What if I change the resources location. That would mean that my consumers would need to programmatically make and OPTIONS call for the resource to figure out all of the relations. Maybe not a bad thing, but feels like a little weird.
So, how do people handle this kind of thing?
Final notes: I get the fact that I don't really want a "leaking" abstaction here and have my database peaking thru the API layer, but the fact remains that there is a foreign_key constraint on this existing database and any insert that doesn't have a valid pos_location_type_id is raising an error.
Also, I'm not trying to open up the URI vs. ID debate. Whether the user has to use the pos_location_type_id int value or a URI doesn't matter for this discussion. In either case, they have no idea what to send me.
I've worked with this kind of stuff in the past. I think there is two ways of approaching this problem, the first you already said it, allow an endpoint for users of the API to know what is the id-like value of the pos_location_type. Many API's do this because a person developing from your API is gonna have to read your documentation and will know where to get the pos_location_type values from. End-users should not worry about this, because they will have an interface showing probably a dropdown list of text values.
On the other hand, the way I've also worked this, not very RESTful-like. Let's suppose you have a location in New York, and the POST could be something like:
POST /pos/new_york/
You can handle /pos/(location_name)/ by normalizing the text, then just search on the database for the value or some similarity, if place does not exist then you just create a new one. That in case users can add new places, if not, then the user would have to know what fixed places exist, which again is the first situation we are in.
that way you can avoid pos_location_type in the request data, you could programatically map it to a valid ID.

Can you build a truly RESTful service that takes many parameters?

After reading an article on REST ("Restful Grails"), I have gotten the impression that it is not possible to truly conform to a REST style in a service that demands a lot of parameters. Is this so? All the examples I have seen so far seem to imply that true REST style services are "parameterless". Using parameters would be RPC-ish and not truly RESTful.
To be more specific, say we have a service that returns graph data for stock prices, and this service needs to know the start date, end date, the currency, stock name, and whatever else might be applicable. In any case, at least 4-5 parameters are needed to retrieve the information needed.
I would imagine the URL to be something like this : /stocks/YAHOO?startDate="2008-09-01"&endDate=...
("YAHOO" is here a made-up stock name).
Would this really be REST or is this more RPC-like, what the author of the aforementioned article calls "GETful" (i.e. just low ceremony rpc)?
You can see the querystring as a filter on the resource you are GETing. Here, your resource is the stock prices of yahoo. Doing a GET on that resource give you all the available data, or the most recents. The query string filter the prices you want. Content negociation allow you to change the representation, e.g. a png graph, a csv file, and so on. To add a price, simply POST a representation (e.g. CSV) to the same resource.
The "restfulness" is not realy in the URL itself, since URIs are obscures to client, but in the way you interact with resources themselves identified by their URI
Feel free to use as many parameters as you need to identify the resource you wish to access. REST doesn't care.
Why would you think it is not possible?
Google uses REST for their charts api, and they take alot of params:
