Is there a way to either display the native Google Chrome bookmark bar in a custom startpage, or fetch its content and display it on my own?

I'm running a simple custom Google Chrome startpage consisting of a background .gif and a google searchbar. However, Google Chrome interprets it as something other than the default startpage, and thus won't show the native bookmark bar, unless the option to show it everywhere is checked (which is awkard for my monitor resolution).
The Google Chrome bookmarks file is located at C:\Users\UserName\AppData\Local\Google\Chrome\User Data\Default\bookmarks,below I'll paste a sample of its structure.
Just looking at this, do you think there's a way to either show the native bookmark ONLY in my custom startpage, or to fetch the information in that bookmarks file and display it on my own?

Query language for JSON or how to use Javascript/Lua in Python?

I'm looking solution to query JSON that extracts specific data.
This solution will be embedded inside our Python software (more exactly Python AWS Lambda) and the user should have the ability to specify such query string in GUI.
For example, we have such JSON and I would extract "nazwisko_weterynarza.value" from "files" array if "typ_dokument" is equal to "szczepienie" and "data_szczepienia" is equal to 3434343.
I've tried this using JSON Path but I've failed.
What about embedded Lua/Javascript in Python, but how to create a 'sandbox' to be sure that such a solution will be safe?
{
"files" :
[
{
"meta": {
"updated": 555555,
"attributes": [
{
"typ_dokumentu":
{
"formula_type": "NONE",
"formula": "",
"value_type": "string",
"value": "szczepienie",
"updated": 5345435435345
}
},
{
"data_szczepienia":
{
"formula_type": "NONE",
"formula": "",
"value_type": "int",
"value": 3434343,
"updated": 5345435225345
},
},
{
"nazwisko_weterynarza":
{
"formula_type": "NONE",
"formula": "",
"value_type": "string",
"value": "Nowak",
"updated": 5345435225345
}
}
]
}
},
{
"meta": {
"updated": 555555,
"attributes": [
{
"typ_dokumentu" :
{
"formula_type": "NONE",
"formula": "",
"value_type": "string",
"value": "Certyfikat urodzin",
"updated": 5345435435345
}
},
{
"data_urodzin" :
{
"formula_type": "NONE",
"formula": "",
"value_type": "int",
"value": 8888888,
"updated": 5345435225345
}
}
]
}
}
]
}

The AWS JSON (reference) path queries are not capable enough. Some more advanced JSONPath processors can do it, eg. using Jayway's JsonPath we could run a query like this:
$.files..meta.[?(#.attributes[*].typ_dokumentu.value contains 'szczepienie' && #.attributes[*].data_szczepienia.value contains '3434343')]..nazwisko_weterynarza.value
Reurns ["Nowak"] (You can try it online).
I don't know what you mean by embedded JavaScript/Lua, but in any event, you could create a web service that does the querying for you leveraging an implementation of your choice. Security wouldn't be an issue as long as your API is properly secured.

validate json against schema in javascript

Question:
Is there a plain or native javascript way to validate a JSON script against a JSON schema?
I have found lots of libraries on Github, but no native/plain solution. Does EcmaScript not have a specification for this? and do none of the browsers (or nodejs) have a way to validate JSON natively?
Context of Question:
I have a very complex schema that I developed.
It is supposed to work along with a script that requires that the JSON data passed into it to comply with the schema.

Simply, no.
There was something called JSON Schema, which was an Internet Draft which expired in 2013. Internet Drafts are the first stage to producing an Internet Standard. See more about it at the official site, as it seems to potentially still be actively developed, although it is not (to my knowledge) in widespread use.
An example of the schema:
{
"$schema": "http://json-schema.org/schema#",
"title": "Product",
"type": "object",
"required": ["id", "name", "price"],
"properties": {
"id": {
"type": "number",
"description": "Product identifier"
},
"name": {
"type": "string",
"description": "Name of the product"
},
"price": {
"type": "number",
"minimum": 0
},
"tags": {
"type": "array",
"items": {
"type": "string"
}
},
"stock": {
"type": "object",
"properties": {
"warehouse": {
"type": "number"
},
"retail": {
"type": "number"
}
}
}
}
}
will validate this example JSON:
{
"id": 1,
"name": "Foo",
"price": 123,
"tags": [
"Bar",
"Eek"
],
"stock": {
"warehouse": 300,
"retail": 20
}
}

There seems to be at least one pure JS solution now (https://github.com/tdegrunt/jsonschema) available via npm (https://www.npmjs.com/package/jsonschema). I am not a contributor, although I appreciate their work.

Show latest facebook post on website

I'm having trouble in showing the latest post of my Facebook page in my website without using PHP since the website is not hosted in an Apache server.
What I've done till now:
Created a Facebook app and generated an Access token.
Access to Facebook Developer Graph explorer, and used GET method
https://developers.facebook.com/tools/explorer?method=GET&path=nextgenerationmorocco%2Ffeed%3Flimit%3D1&version=v2.0
The result after clicking on Graph Explorer submit button:

How can I use Javascript to fetch these information and show them on my website : "message", "from", "created_time"? Any help will be highly appreciated since I'm new to Javascript and Facebook developers!

You alternatively may use Facebook Likebox plugin to show your recent posts in your website.

Q1: What is this error ?
Q2: How to solve it?
P.S.: (Tested on Qt 5.2b & 5.1.1)

Bug was actually some missed debugging log in Qt. Upon creating Bugtrack issue problem was adressed and will be solved in next stable release (Qt 5.2.0).
