1. Introduction
Though cross-site scripting (XSS) is technically trivial to mitigate through proper escaping techniques, it remains a somewhat pervasive risk to web applications. Content Security Policy attempts to contain this risk by giving developers more control over the way script is executed on a given page, and developers have had moderate success at rolling it out. They’ve also expressed more than a little frustration with the complexity that’s crept into CSP over time.
Originally, CSP aimed to address script injection attacks by limiting the sources from which
scripts could be loaded. Over time, we learned that limiting scripts' sources was not a terribly
effective way of addressing the problem. [CSP-IS-DEAD] shifted experts' recommendations away from
a list of allowed sources for script, and towards more robust verification of individual script
elements via nonce
attributes on the one hand, or integrity verification on
the other (see Content Security Policy §8.4 Allowing external JavaScript via hashes).
The [ARTUR] proposal is a tounge-in-cheek proposal that’s a fairly bad idea as specified, but seems like an interesting foundation conceptually. If we step back from CSP’s current syntax, and the contortions it takes to remain backwards compatible, it seems like we could extract a concise and comprehensible mechanism that would encompass the kinds of requirements that hard experience has taught us can be effective (e.g. those expressed in [STRICT-CSP]):
-
Turn off dangerous parts of the platform that influence scripting (e.g.
base
,embed
, andobject
. -
Create an out-of-band signal that a given script is intended to execute (e.g. the aforementioned nonces and hashes).
-
Allow developers to roll the above out in a report-only manner.
This document aims to build upon that conceptual foundation, defining a Scripting Policy that governs the way script executes within a given context, focused entirely on mitigating injection attacks in a way that developers can easily deploy.
1.1. Examples
Most users would be well-served with the following policy:
Scripting-Policy: nonce=number-used-once
This would have the effect of:
-
Executing "parser-inserted" script iff it has a
nonce
attribute matching the header-specified nonce (e.g.<script nonce="number-used-once">...</script>
), and executing all non-"parser-inserted" script in a manner similar to CSP’s'strict-dynamic'
keyword (see Content Security Policy §8.2 Usage of "'strict-dynamic'"). -
Preventing
base
from changing the meaning of relative URLs. -
Blocking
eval(
, while allowingDOMString
)eval(
.TrustedScript
) -
Blocking inline event handlers, XSLT, navigation to
javascript:...
,embed
, andobject
.
This is a pretty reasonable set of hurdles to put in front of an attacker.
Users with complicated sites might need more complicated policies that take advantage of optional features, perhaps along the lines of:
Scripting-Policy: integrity=(hash1 hash2 hash3 hash4), report-to=name, trusted-types-policy=policyName Scripting-Policy-Report-Only: integrity=(hash1 hash2 ...hash18 ... hash37), eval=block, dynamic-loading=checked, report-to=name, trusted-types-policy=policyName
1.2. Threat Model
Scripting Policy aims to deal soley with injection attacks that cause script execution. It does not try to affect resource loading, mitigate data exfiltration, nor does it gate access to any feature unrelated to script execution.
This mechanism assumes an attacker can:
-
Cause a server to output unexpected content directly into the body of any given response, leading to "reflected" cross-site scripting.
-
Manipulate the inputs to client-side code, causing "stored" or "DOM-based" cross-site scripting.
It does not address other, related attacks. In particular, it assumes that attackers cannot reliably inject headers into a server’s response.
1.3. Overview
This section is non-normative (but hopefully helpful anyway).
At its core, this story this document wants to tell is the following:
-
Scripting Policy objects define the ways in which script can be executed within a given Document, Worker, etc. They have a number of properties that influence different aspects of script execution, defined in some detail in § 2 Framework.
-
These policies are delivered as HTTP response headers:
Scripting-Policy
defines a policy to be enforced in a given context, andScripting-Policy-Report-Only
a policy to be reported upon, but not enforced.The headers' syntax is defined in § 2.1 Scripting Policy HTTP Response Headers, and parsing rules are in § 2.2 Parsing Scripting Policy Headers.
-
Policies are bound to
Document
,WorkerGlobalScope
, andWorkletGlobalScope
objects when each is initialized. Each object obtain a policy from the HTTP response used when initializing the document or worker, or from the context responsible for the document’s navigation or worker’s instantiation if that response has a local scheme (e.g.data:
,about:
,blob:
, etc.). These details are spelled out in § 2.4 Initialize a Document’s Scripting Policy and § 2.5 Initialize a global object’s Scripting Policy. -
A policy’s effects are enforced in a given context through hooks in HTML:
-
Nonces and hashes are enforced by policy in HTML’s prepare a script algorithm, and rely upon the existing
nonce
andintegrity
attributes, respectively, for enforcement. Hashes further rely upon Subresource Integrity [SRI] enforcement in Fetch’s main fetch algorithm. -
Inline event handlers rely upon integrity assertions for enforcement. Details in § 2.6.2 Checking Inline Event Handlers.
-
base
's effects are gated via hooks in the set the frozen base URL algorithm, detailed in § 2.6.4 Checking <base>. -
embed
andobject
are gated via hooks in their respective intialization mechanisms, detailed in § 2.6.5 Checking <embed> and <object>.. -
eval()
is gated via HTML’s implementation of JavaScript’s HTML’s implementation of JavaScript’sHostEnsureCanCompileStrings()
abstract operation, detailed in § 2.6.3 Checking String Compilation (eval() and friends). -
Reporting relies upon the Reporting API [REPORTING], defining a "
scripting-policy
" report type via theScriptingPolicyReportBody
interface. Details in § 2.7 Reporting Violations.
-
The rest of the document’s structure follows this general outline: § 2 Framework defines the concepts we’ll need, and the header delivery mechanism. § 2.3 Policy Application shows how policies are associated with the contexts that love them. § 2.6 Policy Enforcement explains how HTML and Fetch make decisions about how code is executed.
Enjoy!
1.4. Dependencies
The rest of the document relies upon Structured Headers to define policies' header syntax [I-D.ietf-httpbis-header-structure]. It also depends upon the Infra Standard for a number of foundational concepts used in its algorithms and prose [INFRA].
2. Framework
A Scripting Policy defines the characteristics of
script execution in a given context, and may have effect on a Document
, WorkerGlobalScope
,
or WorkletGlobalScope
, as described in § 2.4 Initialize a Document’s Scripting Policy and § 2.5 Initialize a global object’s Scripting Policy.
Each policy has a nonce member, which is either null
or a string representing a cryptographic "number-used-once". Unless otherwise specified, its value
is null
.
Note: The nonce
member defines a "number-used-once" which must be reflected in script
elements' nonce
attribute in order to enable script execution. This check is
performed during HTML’s prepare a script algorithm, as described in § 2.6 Policy Enforcement.
Each policy has an integrity member, which is either null
, or a list either null
or a list of integrity metadata objects. Unless otherwise specified, its
value is null
.
Note: The integrity
member is a list of integrity metadata that define the set of scripts
which can be executed on a given page, layering on top of [SRI] for enforcement. This check is
performed during Fetch’s main fetch algorithm, as described in § 2.6 Policy Enforcement.
Each policy has an eval member, which is either "allow
",
"blocked
", or "allow-trustedscript
". Unless otherwise specified, its value is
"allow-trustedscript
".
Note: The eval
member influences the way eval()
is processed (shocking, right?). "allow
"
places no restriction upon eval()
. "blocked
" causes both eval(TrustedScript)
and eval(DOMString)
to throw. "allow-trustedscript
" causes eval(DOMString)
to throw, but allows eval(TrustedScript)
to execute. This is detailed in § 2.6.3 Checking String Compilation (eval() and friends).
Each policy has a report-to member, which is either null
,
or a string representing a reporting group, as defined in [REPORTING].
Unless otherwise specified, its value is null
.
Note: The report-to
member wires Scripting Policy enforcement up to the Reporting API in order to
inform developers about violations on their pages. This is detailed in § 2.7 Reporting Violations.
Each policy has a trusted-types-required-for member, which
is either null
, or a list of strings representing categories for which Trusted Types are
enforced. Unless otherwise specified, its value is null
.
Note: The trusted-types-require-for
member configures Trusted Type enforcement. The only currently
valid category is "script
".
Each policy has a dynamic-loading member, which is either
"allow-non-parser-inserted
", or "check-non-parser-inserted
". Unless otherwise specified, its
value is "allow-non-parser-inserted
".
Note: The dynamic-loading
member controls how script that executes in a given context can cause
more script to execute. "allow-non-parser-inserted
" means that non-[=script/"parser-inserted"=]
scripts will execute, regardless of nonce or integrity enforcement. "check-non-parser-inserted
" will not privilege non-[script/"parser-inserted"=]
script in any way, applying all checks that were applied to the original script.
Names are hard, but {allow,check}-non-parser-inserted
are terrible.
Scripting Policies are often found in a Scripting Policy pair, combining
one enforced policy with one policy which is unenforced, and merely reported upon. This is a pair whose first item is named enforced and whose second item is named report-only.
Both items are either null
or a Scripting Policy object. Unless otherwise
specified, their values are both null
.
2.1. Scripting Policy HTTP Response Headers
Servers can serialize Scripting Policy objects, and deliver them to user agents via HTTP
response headers that declare the scripting requirements for a given response. The Scripting-Policy
HTTP response header informs a user agent about
the scripting requirements which are to be enforced for a given response. The Scripting-Policy-Report-Only
HTTP response header has the same
grammar and semantics as Scripting-Policy
, but declares a policy that is not
enforced in a given context, but merely reported upon.
 Their ABNF is:
Scripting-Policy = scripting-policy-dict Scripting-Policy-Report-Only = scripting-policy-dict scripting-policy-dict = sh-dictionary
Note: The sh-dictionary type is defined along with Structured Header’s dictionary concept in Section 3.2 of [I-D.ietf-httpbis-header-structure].
The scripting-policy-dict
dictionary MAY contain one or
more of the following members:
- nonce
-
The member’s value is a token, which maps to the Scripting Policy's nonce member.
- integrity
-
The member’s value is a list of token values, which are processed as integrity metadata values, and map to the Scripting Policy's integrity member.
- eval
-
The member’s value is an enum represented as one of the following tokens: "
allow
", "blocked
", and "allow-trustedscript
". It maps to the Scripting Policy's eval member. - report-to
-
The member’s value is a token, which maps to the Scripting Policy's report-to member.
- trusted-types-required-for
-
The member’s value is a list of token values, which maps to the Scripting Policy's trusted-types-required-for member.
- dynamic-loading
-
The member’s value is an enum represented as one of the following tokens: "
allow-non-parser-inserted
", and "check-non-parser-inserted
". It maps to the Scripting Policy's dynamic-loading member.
Both headers are currently meaningful only for responses that result in a navigation to a new
document, as well as for responses that are executed as Worker
, SharedWorker
, and ServiceWorker
. Detailed processing rules are found in § 2.6 Policy Enforcement.
2.2. Parsing Scripting Policy Headers
-
Let headers be r’s header list.
-
Let result be a new Scripting Policy pair.
-
Let header be the result of getting
Scripting-Policy
from headers. -
If header is not
null
, set result’ enforced to the result of obtaining a Scripting Policy from header. -
Let header be the result of getting
Scripting-Policy-Report-Only
from headers. -
If header is not
null
, set result’ report-only to the result of obtaining a Scripting Policy from header. -
Return result.
null
if no policy can be parsed successfully.
-
Let policy be a new Scripting Policy object.
-
Let struct be the result of parsing a Structured Header with an
input_bytes
of header and aheader_type
of dictionary.If parsing fails, return
null
. -
For each key → value of struct, byte-lowercase key and switch on the result:
- "
dynamic-loading
" -
-
If value is not contained in the list « "
allow-non-parser-inserted
", "check-non-parser-inserted
" », continue. -
Set policy’s dynamic-loading member to value.
- "
eval
" -
-
If value is not contained in the list « "
allow
", "allow-trustedscript
", "block
" », continue. -
Set policy’s eval member to value.
- "
integrity
" -
Parse the integrity metadata, similar to the definition SRI §3.3.3 Parse metadata.. This might be as simple as joining the list on space, and running it through exactly that algorithm.
Ensure that we normalize the values to base64 from base64url.
- "
nonce
" - "
report-to
" - "
trusted-types-required-for
" -
-
If value is not contained in the list « "
script
" », continue. -
Set policy’s trusted-types-required-for member to value.
- "
-
Return policy.
Note: Parsing errors fail open for compatibility with future changes to the dictionary names and values, as well as the underlying syntax. In particular, if parsing fails because the header cannot be interpreted as a Structured Header per the parsing rules defined in [I-D.ietf-httpbis-header-structure], no policy will be applied. This explicitly prioritizes forward compatibility with future iterations of Structured Headers, which may be surprising. User agents are encouraged to warn developers in this case.
2.3. Policy Application
Each context that can execute script has at most one Scripting Policy that governs script execution in that context.
Monkeypatching [HTML]:
Document
objects have a scripting policy, which is a Scripting Policy pair.
WorkerGlobalScope
objects have a scripting policy, which is a Scripting Policy pair.
WorkletGlobalScope
objects have a scripting policy, which is a Scripting Policy pair.Environment settings objects have an algorithm to obtain a scripting policy, defined as follows:
A
Window
objects’s environment settings object's scripting policy algorithm returns the scripting policy of theWindow
's associated Document.A
WorkerGlobalScope
objects’s environment settings object's scripting policy algorithm returns the scripting policy of theWorkerGlobalScope
.A
WorkletGlobalScope
objects’s environment settings object's scripting policy algorithm returns the scripting policy of theWorkletGlobalScope
.
2.4. Initialize a Document’s Scripting Policy
A Document
's scripting policy comes from one of two places: the response to
which the user agent navigated, or the environment settings object responsible for a navigation
to a local scheme (e.g. data:
, blob:
, about:
). In particular, note that this latter case
covers <iframe srcdoc>
.
Document
(document), a response (response), and a request or null
(request), the user agent can initialize a Document
's Scripting Policy by executing the following steps:
-
If request is not
null
, and response’s url's scheme is a local scheme:-
Set document’s scripting policy to a copy of request’s client's scripting policy.
-
Return.
Does this cover
about:srcdoc
? Presumably this will be simplified in the future. <https://github.com/whatwg/html/issues/4926> -
-
Set document’s scripting policy to the result of obtaining a Scripting Policy pair from response.
This algorithm should be called from HTML’s create and initialize a Document object algorithm, directly after the existing hook for CSP:
Monkeypatching [HTML]'s create and initialize a Document object algorithm:
Initialize a
Document
's Scripting Policy given document, response, and request.
2.5. Initialize a global object’s Scripting Policy
A global object's scripting policy comes from one of two places: the response used to initialize a given worker, or the environment settings object responsible
for intializing a worker from a local scheme (e.g. new Worker('data:...');
)
-
If response’s url's scheme is a local scheme:
-
Assert: global is a
DedicatedWorkerGlobalScope
, aWorkletGlobalScope
, or aSharedWorkerGlobalScope
with one item in its owner set. -
With the single owner in global’s owner set, set global’s scripting policy to a copy of owner’s relevant settings object's scripting policy.
-
Return.
Is the assertion above correct? Presumably this will be simplified in the future. <https://github.com/whatwg/html/issues/4926>
-
-
Set global’s scripting policy to the result of obtaining a Scripting Policy pair from response.
This algorithm should be called from HTML’s run a worker algorithm, directly after the existing hook for CSP:
Monkeypatching [HTML]'s run a worker algorithm:
Obtain script ...
In both cases, ...
...
Initialize a global object’s Scripting Policy given worker global scope and response.
2.6. Policy Enforcement
2.6.1. Checking Nonces and Hashes
Scripting Policy’s restrictions on script
execution are generally performed during HTML’s prepare a script algorithm, before requests are fired for externalized scripts, and prior to
evaluating inline scripts.
Note: If a policy sets requirements for both a nonce and some set of integrity, either will be sufficient to allow script execution. That is,
the policy nonce=abcdefg, integrity=(sha256-123456)
would allow execution for each of <script nonce="abcdefg"></script>
, <script integrity="sha256-123456"></script>
, and <script nonce="abcdefg" integrity="sha256-123456"></script>
.
Element
(el), execute the following
algorithm. It will return "Blocked
" or "Allowed
".
-
Assert: el is an
HTMLScriptElement
or anSVGScriptElement
. -
Let enforced be el’s node document's scripting policy's enforced.
-
Let report-only be el’s node document's scripting policy's report-only.
-
If report-only is not
null
: -
If enforced is not
null
: -
Return "
Allowed
".
This relies on SRI doing something useful for inline script blocks. We should probably make that happen. <https://github.com/w3c/webappsec-subresource-integrity/issues/44>
2.6.2.
Match
":
-
Set source to the result of executing UTF-8 encode on the result of executing JavaScript string converstion on value.
-
For each integrity metadata in list:
-
Let expected be integrity metadata’s digest.
-
Switch on integrity metadata’s algorithm:
- "
sha256
" -
-
If expected is a case-sensitive match with the result of base64 encoding the result of applying SHA-256 to source, return "
Matches
".
-
- "
sha384
" -
-
If expected is a case-sensitive match with the result of base64 encoding the result of applying SHA-384 to source, return "
Matches
".
-
- "
sha512
" -
-
If expected is a case-sensitive match with the result of base64 encoding the result of applying SHA-512 to source, return "
Matches
".
-
- "
-
-
Return "
Does Not Match
".
-
Let enforced be el’s node document's scripting policy's enforced.
-
Let report-only be el’s node document's scripting policy's report-only.
-
If report-only is not
null
: -
If enforced is not
null
: -
Return "
Allowed
".
Monkeypatching [HTML]'s event handler content attribute's attribute change steps:
Otherwise:
...
 Checking String Compilation (eval()
and friends)
To address eval()
, Scripting Policy modifies HTML’s implementation of
JavaScript’s HostEnsureCanCompileStrings
abstract operation to include verification against
the context’s policy.
EvalError
if not:
-
Let globals be a list containing callerRealm’s global object and calleeRealm’s global object.
-
For each global in globals:
-
Let enforced be global’s relevant settings object's scripting policy's enforced.
-
Let report-only be global’s relevant settings object's scripting policy's report-only.
-
If report-only is not
null
, switch on its eval value: -
If enforced is not
null
, switch on its eval value:
-
-
Return.
HostEnsureCanCompileStrings()
does not include the string which is
going to be compiled as a parameter. We’ll also need to update HTML to pipe that value through. <https://github.com/tc39/ecma262/issues/938>
Monkeypatching [HTML]'s HostEnsureCanCompileStrings():
Perform ? EnsureCSPDoesNotBlockStringCompilation(callerRealm, calleeRealm). [CSP]
Perform ? EnsureScriptingPolicyDoesNotBlockStringCompilation(callerRealm, calleeRealm).
2.6.4. Checking <base>
Scripting Policy blocks <base>
from pointing to any cross-origin URL, as this can change the
meaning of a script tag in unexpected and dangerous ways.
Element
(el) and a URL (url), execute
the following algorithm. It will return "Blocked
" or "Allowed
".
-
If url’s origin is same origin with el’s node document's relevant settings object's origin, return "
Allowed
". -
Let enforced be el’s node document's scripting policy's enforced.
-
Let report-only be el’s node document's scripting policy's report-only.
-
If report-only is not
null
:-
Report a Scripting Policy violation, using report-only, handler, and el.
-
-
If enforced is not
null
:-
Report a Scripting Policy violation, using enforced, handler, and el.
-
Return "
Blocked
".
-
-
Return "
Allowed
".
Monkeypatching [HTML]'s set the frozen base URL algorithm:
Insert the algorithm above into the current step 3, as follows:
Set element’s frozen base URL to document’s
fallback base URL
, if urlRecord is failure orrunning Is base allowed for Document? on the resulting URL record and document returns "Blocked"eitherIs base allowed by Content Security Policy?
or Is base allowed by Scripting Policy? return "Blocked
" when executed upon theresulting URL record
and document, and to urlRecord otherwise.
2.6.5. Checking <embed>
and <object>
.
Scripting Policy blocks <embed>
and <object>
, as they have capabilities in line with (and
beyond the capabilities of) script execution.
Element
(el), execute the following algorithm.
It will return "Blocked
" or "Allowed
".
-
Let enforced be el’s node document's scripting policy's enforced.
-
Let report-only be el’s node document's scripting policy's report-only.
-
If report-only is not
null
:-
Report a Scripting Policy violation, using report-only, handler, and el.
-
-
If enforced is not
null
:-
Report a Scripting Policy violation, using enforced, handler, and el.
-
Return "
Blocked
".
-
-
Return "
Allowed
".
Monkeypatching [HTML]'s
object
type determination stepsInsert the algorithm above into the current step 2, as follows:
If the element has an ancestor media element, or has an ancestor object element that is not showing its fallback content, or if the element is not in a document whose browsing context is non-null, or if the element’s node document is not fully active, or if the element is still in the stack of open elements of an HTML parser or XML parser, or if the element is not being rendered, or if the Should element be blocked a priori by Content Security Policy? algorithm returns "Blocked" when executed on the element, or if the Should a plugin element be blocked by Scripting Policy? algorithm returns "
Blocked
" when executed on the element, then jump to the step below labeled fallback.
This might be too strict, and we might want to have something akin to CSP’s plugin-types
so folks can allow PDF in user agents that use PDFium? Or have a carveout similar to the sandboxed plugins browsing context flag concept of a "secured plugin"?
2.7. Reporting Violations
Scripting Policy reports provide developers with context when a given page or
worker violates its policy. These violations are reported to developers via the Reporting API,
which exposes violations via the ReportingObserver
interface, as well as via reports delivered to endpoints configured via the Report-To
header as defined in [REPORTING].
Scripting Policy reports have a report type of "scripting-policy
", and are visible to ReportingObservers.
A Scripting Policy report's body is represented in JavaScript by the ScriptingPolicyReportBody
interface:
enum {
ScriptingPolicyViolationType ,
"externalScript" ,
"inlineScript" ,
"inlineEventHandler" }; [
"eval" Exposed =(Window ,Worker ),SecureContext ]interface :
ScriptingPolicyReportBody ReportBody { [Default ]object ();
toJSON readonly attribute DOMString violationType ;readonly attribute USVString ?violationURL ;readonly attribute USVString ?violationSample ;readonly attribute unsigned long lineno ;readonly attribute unsigned long colno ; };
violationType
, of type DOMString, readonly-
This attribute, to your certain astonishment, reflects the violation’s type:
-
"
externalScript
" reflects a violation when fetching a script (e.g.<script src="...">
). -
"
inlineScript
" reflects a violation from an inline script block (e.g.<script>...</script>
). -
"
inlineEventHandler
" reflects a violation from an inline event handler (e.g.<a onclick="...">
). -
"
eval
" reflects a violation fromeval()
,new Function()
, etc.
-
violationURL
, of type USVString, readonly, nullable-
When the
violationType
is "externalScript
", this attribute will contain that script’s URL. It will benull
for any other type. violationSample
, of type USVString, readonly, nullable-
When the
violationType
is not "externalScript
", this attribute will contain additional detail about the violation’s cause. When inline event handlers cause a violation, for example, this attribute will contain the first 40 characters of the handler’s source.When the
violationType
is "externalScript
", this attribute will benull
. lineno
, of type unsigned long, readonlycolno
, of type unsigned long, readonly-
These attributes contain the line and column numbers, respectively, associated with a violation, if the user agent can obtain them. If no positional information can be obtained, these attributes will both be 0.

IP/PDS: Using Inheritance -
Lecture company
Scenario
A Company has a number of employees and shareholders. These people
earn money from the company through salaries, share dividends or both.
The company has a number of types of employees, namely
- Directors
- Engineers
- Sales
- Temporary staff.
Every employee has an employee
number and personal details, such as their name and address.
Permanent Staff
The Directors of the company sit on the board and manage the company.
The Engineers build the products. They have a basic monthly
salary. However, they are often required to work overtime and they
receive a fixed hourly rate for any overtime hours done each month.
The sales staff sell the company's products and can earn commission on
top of their basic monthly salary, depending on their sales
performance. To earn commission they have to surpass the company sales
target of 2500 units per month.
Temporary Staff
The company also employs a number of temporary staff. These do not
have permanent contracts, instead they have a fixed deadline when
their contract terminates.
The temporary staff are split into two
groups, those that are paid weekly and those that are paid
monthly. Those that are paid monthly can do overtime.
Shareholders
- Shareholders have a number of shares in the company and earn a
dividend on these shares.
- Each shareholder also has personal details,
such as their name and address.
- Shareholders can also be employees.
Reports
The company needs to be able to list its employees and shareholders:
Name: Fred Bloggs
Address: 14 Medlock Drive
Employee Number: 5067
Temporary Staff
- Contract terminates 31/03/04
Paid Weekly
Worked 20 hours
The company needs to be able to calculate the pay of each employee and
the share dividend for the shareholders:
Surname:
First Name(s):
Employee Number:
Payment Due: (Per Week/ Per Month)
Task

Hobbies: Listening music,art and craft,creating innovative things.
Strength: Honesty,Self-awareness.
Programming /languages: sql(basics), c,c++, python(basics),


I recently had the “pleasure” of getting started with Google Cloud Storage using Go. It was a hassle, but all’s well that ends well.
Google Cloud Storage, Storage or GCS for short, is a S3 like service from Google. It lets you store files and other “blob” data cheaply and easily. These files can be private or something you share with the world. With public files, Google will cache them automatically to make fetching them faster around the world. See the official Storage page for a longer salespitch.
Storage is a part of the overall Google Cloud Platform that also includes things like Compute Engine and App Engine (comes in two flavours: Standard and Flexible). See the Google Cloud Platform homepage for more.
Go (or golang if you want) is an open source programming language started by some guys at Google and now used by many people for many different things. It’s seen most success within newer, devops like, serverside tools such as Docker, Kubernetes and Consul. This is not the only usecase though, as it’s a general purpose language with many strong points. I currently use it to build back-end systems that talk http, http/2 and websockets with mobile app’s, JS frontends, special hardware etc.
Before we get to the point, I have to rant a little about the Google Cloud Platform (GCP). In many ways I’m a fan. It seems like they understand “no ops” better than almost anybody, and in my opinion App Engine could be the only real PaaS out there. Their pricing model is very nice, with a linear increase in costs as the traffic increases (quite unlike Heroku). With Compute Engine, their EC2-like IaaS, you get automatic discounts when running a server for more than 25% of a month (quite unlike Amazon’s reserved instances). This means there’s no need to “reserve instances” up front. Just run a normal instance for enough time and get automatic discounts. Great!
So, there are many things to like about GCP, but obviously things are not perfect. While the platform itself seems well-engineered, the developer experience can be horrible at times.
If you’re in a hurry and you don’t have anyone with GCP experience I would probably recommend something else. That being said, developing on GCP is fast and easy when you know how to do it. If you can avoid the quirks and gotcha’s, the platform itself in incredibly powerful.
There’s three main problems I’ve seen so far:
The documentation falls into three categories: Correct, Outdated and Just Plain Wrong. It sometimes feels like they are distributed evenly, and therefore only correct 33% of the time, but that’s probably just me being negative.
Related, there’s usually 3 or 4 libraries to do something:
1-2 legacy libraries that you are discouraged to use
1 new, but still in beta and missing some feature, library,
1 lib that’s auto generated and probably works most of the time kind of.
(The documentation, of course, refers to one or all of these seemingly at random).
Quirks and gotchas in the different products. These are actually, for the most part, documented and well known. They can still bite you though if you’re not careful.
We’ll see all these 3 in action here.
I did not start completely from scratch. I already knew Storage pretty well having done something similar with Storage, App Engine Standard and Python.
The question therefore, when starting out, where something like:
When developing on App Engine Standard (AE) you usually run it on your own machine first. The AE tooling helps to simulate some of the AE and Google Cloud Platform services locally. Can these tools simulate Storage locally? This would be useful when writing and testing new code.
Which of the many libraries should I use? Do I need more than one?
I’m working with private (not public) files. How is authentication handled?
These questions answered, in order:
The short answer: No you can not. Use one or more buckets just for testing.
What most people end up doing is to have 1 or more Storage buckets just for development. This actually works pretty well when you get authentication working (quite easy, more on that later). You have to pay for the traffic you upload and download when testing, but the price is so low that it’s just a rounding error for most usecases. Of course, if your files are very large uploading them could take some time. On the other hand, you probably have to upload them sooner or later anyway. And having them in the real Storage makes them accessible to the rest of the Google Cloud Platform, most of which integrates nicely with Storage.
The App Engine Standard tooling includes support for something called “Blobstore” which is the AE specific predecessor to Storage. It has some limited interoperability with Storage: You can tell it to actually store the files in Storage instead of in the old blobstore. I haven’t tried this as I can’t really see any of my projects staying with just the Blobstore for very long. Storage integrates with the rest of the Google Cloud, has many extra features and keeps evolving.
The short answer: Use the new gcloud Go libs: Main page / Storage client docs
This is the newest library and even though it’s marked with “beta” it seems stable enough that people use it in production.
Here are the different libraries I’ve found so far:
See what I meant in my rant? I probably even forgot a couple..
The short answer: Use the gcloud lib mentioned above. Install the gcloud client program if you haven’t already (not related to the gcloud lib, confusing eh? =)
Run:
gcloud beta auth application-default login
on the command line and log in with your Google account.
After reading and googling this stuff for a while I was under the impression that this was more complicated. The above methods uses the developers Google account to authenticate with Storage. This is useful when running locally, but is a bad fit in some situations. You may want the program or machine to authenticate instead of the developer, for example when running automated tests. Therefore there are other ways of authenticating, mainly using Key files and something called Service Account’s.
I haven’t tried this in Go, but the process seems to be:
Generate and download a key from the Cloud Console. You can use an existing Service Account or create a new one. You find this under IAM & Admin ⇒ Service Accounts.
Pass this keyfile to the gcloud library like this:
client, err := storage.NewClient(ctx, option.WithServiceAccountFile("path/to/keyfile.json"))
All that is not necessary to just run code locally against the real Storage. Contrary to the common wisdom (at the time of writing), the helper gcloud command above (gcloud beta auth application-default login) actually works. This makes using the gcloud library a breeze, just do:
client, err := storage.NewClient(ctx).
When running on the Google Cloud Platform the same code just works and you should not have to think too much about authentication and authorization in common scenarios.
One last tip: I could not get auto-detecting of the bucketname, as seen in the docs, to work. This confused me for a long time since it doesn’t throw an error, it just returns an invalid bucketname.
Hopefully this is useful for someone. It took me hours to figure out, but it’s pretty simple and straight-forward when you know how to do it =).


IN LOVE AND WAR 1996
A film review by Timothy Voon
Copyright 1997 Timothy Voon
Cast: Sandra Bullock, Chris O'Donnell, MacKenzie Astin, Emilio Bonucci, Ingrid Lacey, Ian Kelly, Margot Steinberg, Tara Hugo Director: Richard Attenborough Screenplay: Allan Scott, Clancy Sigal, and Anna Hamilton Phelan based on the book HEMINGWAY IN LOVE AND WAR: THE LOST DIARY OF AGNES VON KUROWSKY by Henry S. Villard and James Nagel Cinematography: Roger Pratt
Well she sure ain't no 'Florence Nightingale', but does carry with her a pretty smile and a good sense of humour; and he sure ain't no 'Ernest Hemingway', but he does carry with him a certain amiable, boyish charm highlighted by his kiddy manner; and this definitely ain't no Leo Tolstoy's 'War and Peace', which is why this movie is called 'In Love and War'.
If Attenbourough was hoping to make a film with classy actors, he sure did miss the boat and landed in a muddy puddle. Hey, isn't this the same bus driving, boat saving, while you were sleeping down town lass (Bulllock)? And isn't that the green tomato eating, friend circling, bat loving, boy wonder fomp, of an up town lad (O'Donnell)?
Are we meant to stretch our imaginations to believe that they are meant to be Ernest Hemingway and his war time love interest, nurse Agnes Von Kurowsky? Really Mr Attenborough, it is very unfair of you to ask this lad and lass to stretch their acting skills beyond limits which are considered humanely safe.
Nevertheless, what we do have is a concoction of melodramatic, heart rending mush which goes nicely with lemonade. 'In Love and War' we can draw conclusions that the reason why Hemingway was so brilliant and yet so miserable, was probably because he was dumped by a pretty nurse post-1st World War; and he never had the heart to forgive her. Please spare us the violins.
I'm trying not to be overly nasty with my comments. I enjoyed 'Shadowlands' and I even liked 'Chaplin'; but this movie is just screaming out to be teased. On a positive note, I can freely say that Attenborough's movies are always easy on the eye, and one can sit through them with the same relaxed feel of a Sunday picnic.
Comment: 'In Love and War' we don't find 'An American in Paris', but we do find two juvenile Yankees making hay in Italy.

{% include head.html %}
I work as a Data Scientist at Infor Dynamic Science Labs - located in Cambridge, Massachusetts.
I was a graduate student in Computer Science at the University of Florida, Gainesville. I am passionate about Data Science and everyday I find some reason to get excited by its pervasive use in almost any domain. Is there at all any area where one can't apply Data Science to it? I am eager to make a tangible impact on the world by developing data products.
Also, I am a strong advocate of the role of open-source in aiding future technology. I open-source my projects and look to contribute (atleast in a minimal way) to other open source projects as well, when I find time.
I am a part of the Dynamic Science Labs team where we have worked on building science features for enterprise software and implementing customized solutions for our customers.
I worked with the Data Science Engineering and the Optimization team to improve the optimization of advertising campaigns by developing a diagnostic tool.
It was fun learning the basics of Linear Optimization - especially about infeasiblity in linear programs. Python was the primary programming language I used during the development phase. I enjoyed using IPython Notebooks for any supporting analysis. Ansible was one cool open-source software I got to work while automating the tool. Amazon Web Services like S3, DataPipelines, EC2 etc. and CI services like Jenkins was amongst the other technologies I learnt and enjoyed using.
I worked as student researcher under Dr.Parisa Rashidi. The project I worked on aimed to assist patients by predicting their congnitive distortions from the patients' personal text data.
I helped to develop a sentiment classifier to classify text containing the cognitive distortions into various categories such as 'black and white', 'all-or-nothing' , 'overgeneralisation' etc. Training imbalanced datasets and working with out-of-domain sentiment analysis were some of the aspects I enjoyed working.
During my grad school, I have taken courses related to Data Science such as Machine Learning, Pattern Recognition and Math for Intelligent Systems.
The latter is a math heavy course covering topics in Linear Algebra and Probability Theory. Machine Learning under Prof. Banerjee is one particular course I enjoyed learning - The fact that it was quite theoritical, I got a good grasp of the underlying difference between the different machine learning algorithms and thus was helpful while implementing them.
Working on personal projects give me the freedom to experiment new technologies and learn concepts outside the coursework. I work on a multiple hobby projects to improve my statistics, python development and machine learning chops.
The project involved the use of the statistical concept of Survival Analysis in analyzing the careers of cricketers. The scraped and cleaned player data was used to estimate the survival curves of the players. They were further compared after grouping into different player cohorts. Survival Regression models like COX-PH and Aalen's additive models were used to predict the survival curves and hazard rates of current players.
Update: I got an edited version of the survival analysis published on the yHat data science blog ☺. yHat is a tech company which provides tools and platform for industrial data science applications.
Here, I modelled the batting averages using beta distributions. The simulation of the batting averages was done using animated plots.
Built a predictive model for Golbal Terrorism Database - involved data preprocessing, feature selection and modelling.
Kaggle competitions gave me a chance to implement different machine learning algorithms like Random Forests, AdaBoost, ExtraTrees etc. on real-life datasets.
During grad school, it was great fun working on projects related to Machine Learning and Distributed Operating Systems.
A Content based Recommender System that provides the optimal product to the user was developed. Sentiment Analysis was performed on Amazon customer reviews. Naïve Bayes Classifiers, SVMs and Logistic Regressions using Rapid Miner and Python were implemented. Accuracy achieved: 0.7735.
A distributed system using Akka Actor model in Scala was developed. Bitcoins were mined using SHA-256 algorithm with the required number of leading zeros.CPU performance was measured and analyzed.
An application which simulates Twitter functionalities using Scala and AKKA actor model was built. Functionalities similar to REST APIs such as Post Tweet, Get Tweet using Spray-Can were developed. Hash tag search and Peak hour simulation were also implemented.

I was a bit bored on a snowy Indiana night, so I decided to drive to the local Meijer department store and pick up some Dramamine. I had never taken it before, but my friends praised it for occupying many lonely nights. The store was out of regular Dramamine, so I picked up a two-pack of the 'less drowsy formula.' The benefit? I got two nice little pill bottles.
I downed the 16 tablets at 11:08 p.m., slightly chewing each one so that the chemicals would enter my bloodstream quicker. 30 minutes passed and nothing happened. I then decided to check online to try for a general idea of how long it takes these little guys to kick in. After an hour, I became depressed at my lack of an experience. She brought up a little blip in my drug history when I had eaten an eighth of shrooms and was not affected. I began to wonder if it was just me. I could trip with large doses of DXM, but other than that, I've not had any luck (please note that LSD and mescaline are practically non-existent in my area of the world.) I spent about 30 minutes talking to my friend while watching Nine Inch Nails videos, before I decided that I should listen to Shpongle.
By this point, I was feeling a little sleepy. I had a long, rough day at work, as well as a bit of emotional turmoil, so drowsiness was expected. I fell asleep about 2.5 hours after taking the Dramamine, with no luck what-so-ever. I dreamed the dreams that one dreams when there is some odd force at work. Dreams that my good friends would get busted for selling drugs, dreams where friends told me that I should take more next time, and, of course, dreams of running from the police.
I awoke up around 11 a.m., with a slight headache and a mind full of disappointment, but I suppose it wouldn't hurt to try again, next time with the original formula.

| Prev | Up | Chapter 44. Overview of PostgreSQL Internals | Next |
The executor takes the plan created by the planner/optimizer and recursively processes it to extract the required set of rows. This is essentially a demand-pull pipeline mechanism. Each time a plan node is called, it must deliver one more row, or report that it is done delivering rows.
To provide a concrete example, assume that the top node is a MergeJoin node. Before any merge can be done two rows have to be fetched (one from each subplan). So the executor recursively calls itself to process the subplans (it starts with the subplan attached to lefttree). The new top node (the top node of the left subplan) is, let's say, a Sort node and again recursion is needed to obtain an input row. The child node of the Sort might be a SeqScan node, representing actual reading of a table. Execution of this node causes the executor to fetch a row from the table and return it up to the calling node. The Sort node will repeatedly call its child to obtain all the rows to be sorted. When the input is exhausted (as indicated by the child node returning a NULL instead of a row), the Sort code performs the sort, and finally is able to return its first output row, namely the first one in sorted order. It keeps the remaining rows stored so that it can deliver them in sorted order in response to later demands.
The MergeJoin node similarly demands the first row from its right subplan. Then it compares the two rows to see if they can be joined; if so, it returns a join row to its caller. On the next call, or immediately if it cannot join the current pair of inputs, it advances to the next row of one table or the other (depending on how the comparison came out), and again checks for a match. Eventually, one subplan or the other is exhausted, and the MergeJoin node returns NULL to indicate that no more join rows can be formed.
Complex queries can involve many levels of plan nodes, but the general approach is the same: each node computes and returns its next output row each time it is called. Each node is also responsible for applying any selection or projection expressions that were assigned to it by the planner.
The executor mechanism is used to evaluate all four basic SQL query types: SELECT, INSERT, UPDATE, and DELETE. For SELECT, the top-level executor code only needs to send each row returned by the query plan tree off to the client. For INSERT, each returned row is inserted into the target table specified for the INSERT. This is done in a special top-level plan node called ModifyTable. (A simple INSERT ... VALUES command creates a trivial plan tree consisting of a single Result node, which computes just one result row, and ModifyTable above it to perform the insertion. But INSERT ... SELECT can demand the full power of the executor mechanism.) For UPDATE, the planner arranges that each computed row includes all the updated column values, plus the TID (tuple ID, or row ID) of the original target row; this data is fed into a ModifyTable node, which uses the information to create a new updated row and mark the old row deleted. For DELETE, the only column that is actually returned by the plan is the TID, and the ModifyTable node simply uses the TID to visit each target row and mark it deleted.


How_I_Met_Your_Mother
How I Met Your Mother is a comedy about Ted and how he fell in love. It all starts when Ted's best friend, Marshall drops the bombshell that he's going to propose to his long-time girlfriend, Lilya kindergarten teacher. At that moment, Ted realizes that he had better get a move on if he too hopes to find true love. Helping him in his quest is Barney a friend with endless, sometimes outrageous opinions, a penchant for suits and a foolproof way to meet women. When Ted meets Robin he's sure it's love at first sight, but destiny may have something else in store.

The REVOLT wind turbine is super-easy to install, assemble, and operate.
Installation & Assembly:
Please use care and common sense when installing your REVOLT.
- Select a location that is windy and where the windmill can be hung as high and as safely as possible.
- Make sure the unit will be located a reasonable distance away from objects, people, or structures so that the blades won't hit anything.
- Hang the windmill using the included wire rope or use a hook or bracket.
- The customer is responsible for attaching the wire rope to something that is strong enough to support the windmill.
- The wire rope has a breaking strength of 2000 pounds and must be securely attached at each end. When installed correctly, the force on the cable will be less than 50 pounds.
- Please consult an expert to determine your specific needs.
Operation:
Wait for the wind to blow! When it does, the windmill will begin producing power immediately. An on-board LED bulb located on the windmill will light up to let you know that you are producing power.
USE CARE SO THAT ANY WIRES CONNECTED TO THE WINDMILL DO NOT GET TANGLED IN OR HIT BY THE BLADES. DO NOT ATTEMPT TO HANG YOUR PHONE OR ANY OTHER DEVICE FROM THE WINDMILL.
Maintenance
Windmills have moving parts and things with moving parts wear out over time. The magnets in the alternator can wear out from overheating, bearings can corrode over time due to excessive salt, moisture, or dust, plastic parts can become brittle and break from long-term UV exposure, and batteries have limited lifetimes. The good news is that all of the parts of the REVOLT can be replaced safely and inexpensively. All replacement parts will be available for order from our website soon. Contact us if you cannot find your replacement part(s) online.
If you have any questions about the installation, assembly, operation, or maintenance of your REVOLT, please contact us or visit our FAQs page.

Orchestrator.js offers web-based IDE for implementing apps in heterogenous, multi-user and multi-device environment. The Web Console can be used for implementing the apps, interactions, and device capabilities. Moreover, the IDE offers tools for testing purposes: it is easy to monitor device states, read debug messages directly from web browser's console, and also developers can manually trigger interactions for a predefined set of devices.
OJS currently runs in Amazon cloud, but is freely available from GitHub, and can be easily hosted on any computer with a network connectivity. The devices are constantly connected to the Orchestrator.js. On client-side we currently support Android, iOS, and devices capable of running Python/Qt.
Detailed Development Tutorial by Benítez: PDF.
OJS has been described in details: Building and Programming Ubiquitous Social Devices.
With Orchestrator.js it is easy to implement context-aware applications for a heterogenous set of device. The middleware offers publish-subsrcibe API that is easy to utilize in app implementations. The devices constantly report their state to the Orchestrator.js Device Registry, which publishes updates whenever devices' contextual data changes.
1) Devices connected to OJS measure their context with their sensors, and report this to Device Registry
2) When the data changes (newValue != oldValue), Device Registry publishes the change through pub/sub API.
3) Applications (Apps) run in cloud and receive events through pub/sub API, and also can monitor other sources, e.g. by polling with HTTP.
4) An app then decides when the context of a device is right and tries triggering an action with REST API.
5-7) When OJS receives the trigger, it fetches receurces from repositories.
8-11) Finally, OJS begins the coordination process, commanding participants with their capabilities.
The applications in Orchestrator.js are based on Action-oriented Programming Model (AcOP). This programming model has the following three main concepts:
Apps monitor device contexts, and out-side sources like social media services, such as Facebook, Twitter and so on. Based on the observations and logic defined by the developer, the app triggers actions. So app defines when and what interactions (actions) should take place.
Actions define how the devices interact with each other and as well as with users. An action can be very short, like just greeting each other, or long-lasting, like a game.
Capabilities are used to describe how a device appears to the system, what a device can or is allowed to do, and in what interactions the device can take part to. The capability can either be very generic, like Talking-capability that allows device to speak, or more specific, like Apocalympics-capability which allows the device to participate to Apocalympics game.

Lately we have been working with BLE support for OJS.
Basically this means that the devices can now be coordinated with two paradigms (A) and (B).
A) In the new paradigm one of the devices participating into an action receives a trigger from OJS through its Communication Layer (A.1), then downloads the action definition JavaScript from server, and finally begins the coordination process (A.2), coordinating itself as well as other participants.
B) In the old paradigm Orchestrator Core (a centralized server) was coordinating all the participating devices (B.1 and B.2).
C) We have also added a support for detecting orher devices and BLE beacons (iBeacon).

doc2mat - Converting documents into the vector-space format used by CLUTO
doc2mat [options] doc-file mat-file
doc2mat takes as input two arguments. The first argument is the name of the file that stores the documents to be converted into the vector-space format used by CLUTO and the second argument is the name of the file that stores the resulting document-term matrix.
doc2mat convertes a set of documents into a vector-space format and stores the resulting document-term matrix into a mat-file that is compatible with CLUTO's clustering algorithms.
The documents are supplied in the file doc-file, and each document must be stored on a single line in that file. As a result, the total number of documents in the resulting document-term matrix will be equal to the number of rows in the file doc-file.
doc2mat supports both word stemming (using Porter's stemming algorithm) and stop-word elimination. It contains a default list of stop-words that it can be either ignored or augmented by providing an file containing a list of words to be eliminated as well. This user-supplied stop-list file is supplied using the -mystoplist option and should contain a white-space separated list of words. All of these words can be on the same line or multiple lines. Note that stop-word elimination occurs before stemming, so the user-supplied stop words should not be stemmed.
The tokenization performed by doc2mat is quite straight-forward. It starts by replacing all non-alphanumeric characters with spaces, and then the white-space characters are used to break up the line into tokens. Each of these tokens is then checked against the stop-list, and if they are not there they get stemmed. By using the -skipnumeric option you can force doc2mat to eliminate any tokens that contain numeric digits. Also, by specifying the -tokfile option, doc2mat will create a file called mat-file.tokens, in which each line stores the tokenized form of each document.
Some of leading fields of each line can potentially store document specific information (e.g., document identifier, class label, etc), and they can be ignored by using the -nlskip option. In cases in which -nlskip is greater than zero, the -nlskip leading tokens are treated as the label of each row and they are written in the file called mat-file.rlabel.

The prompt of this blog post was to do additional research on a hases and arrays. While I think there are a number of interesting distinctions to make between these two classes of objects, I'm prioritizing some time spent practicing coding with them more in the bonus challenges. I will return to add to this blog more later this week when I have some more time. ;)
