Deploying simple React app with Serverless / AWS
I am learning Serverless and AWS for work. Here is what I did to deploy a basic app with Serverless.
This is assuming you already have an AWS account, and have installed Serverless, the AWS SDK, and set up your AWS credentials on your machine.Simply put, though:
- To install Serverless I ran this command:
npm i serverless -g
- To install the AWS SDK I ran this command:
npm i aws-sdk -g
- Once you’ve set up an AWS account you can set up a new user in IAM, and save your credentials on your machine. This video shows that set-up.
In this case I already had a project made, which I set up using create-react-app
. You can also set up a new serverless app by creating a new folder and running serverless create --template aws-nodejs
. This is assuming you are using Node.js in the backend. There are many different runtimes you can use and templates available. You can also run create-react-app
after creating your serverless template. The order you do this doesn’t seem to matter, as long as you have all the files you need.
This article from Serverless explains services, and all associated files, very well.
To deploy static pages to an S3 bucket on AWS, I installed serverless-finch in my project using npm i --save-dev serverless-finch
.
When deploying a React app it is important to run the command npm run build
, so you get a build folder in your project directory. This is where all your static files end up including your index.html, which S3 needs to find in order to deploy your site.
Inside the serverless.yml file
Setting up a new serverless app will give you a handler file (in my case, handler.js), a .gitignore, and a serverless.yml file. serverless.yml is where you configure your service. Serverless uses this file to work with AWS to deploy your app.
The following is what I have in my serverless.yml file:
service: react-practice
provider:
name: aws
stage: ${opt:stage, 'dev'}
runtime: nodejs12.x
region: us-west-2
functions:
hello:
handler: handler.hello
# The following are a few example events you can configure
# NOTE: Please make sure to change your handler code to work with those events
# Check the event documentation for details
events:
- http:
path: hello
method: get
plugins:
- serverless-finch
custom:
client:
bucketName: julia-practice-react1
distributionFolder: /build
errorDocument: index.html
“service” essentially means project. It’s where you define all your functions, resources, events, plugins, and so on. Here you give the service a name.
Under “provider” is where you specify that you are using AWS and configure your runtime, region, stage, etc. Stage refers to stage of development which includes development, QA, or production. Here the “dev” stage is default, if you don’t specify a stage when you deploy.
Under each function you can have events. These are events that trigger the function to execute. In this example, and HTTP “get” request is triggering the “hello” function to execute.
If you have a “resources” section, these are the resources that your functions use when they execute. These could include database tables.
Note that under “plugins” I added “serverless-finch”.
Under “custom” and “client” we configure S3.
bucketName the bucket where S3 will place our files. It must be a globally unique name, meaning no one else in the world have have a bucket with this name.
distributionFolder is where S3 should look for our files. For React we use “/build”, since that’s where our index.html is.
S3 also requires you have an errorDocument specified. Since this is just a simple app I didn’t make one and just left it as index.html.
What Serverless does with the serverless.yml file
Serverless takes the serverless.yml file and translates it into an AWS CloudFormation template.
CloudFormation is an AWS service that allows you to manage all your AWS services/resources. You would write a template describing everything you want, and CloudFormation configures it for you.
This sounds like an improvement over configuring everything yourself in the AWS management console, though these files can still get pretty long and take time to create. That’s where Serverless comes in. Serverless takes your serverless.yml file and creates CloudFormation templates for you.
Here’s an article describing deployment with Serverless
Deployment
Note: you can set up different commands in the “scripts” section of your package.json file.
For backend stuff, especially for Lambda functions, run sls deploy --aws-profile={whatever name you set up in your aws credentials file}
To deploy the client side, into your S3 bucket, run this command sls client deploy --aws-profile={whatever name you set up in your aws credentials file}
Your screen should look something like this if successful. You will see a link you can go to and view the site.
Errors
I got an error reading “Serverless Error: Access Denied”. This seemed strange because I never got this error for the backend deploy, so I thought it must have to do with S3. I fixed this by making my bucket public, but I don’t think this is very secure so I need to look into this further.
Another error said that I was not in the correct region. This was because my bucket and my serverless.yml file “region” did not match. I just had to quickly update my .yml file and there error was solved. I could now see my site.


.============= Meeting 28-Mar-2012 =============
Agenda
======
1. Demo of the archive service - (*David*)
2. review AIs
DH by 27th Mar: Add inserstions into MK's proposed changes document to illustrate the alternative for moving the introspection interface.
MS/GW by Fri 23: Tag all pv*Java and pv*CPP repos beta.1.1. alphaJava and alphaCPP tagged too
3. easyPVA review / Test results (*Marty*)
4. Open Issue.....
structures should consist of members which consist of name plus a s a type object. This isn't incoconsistent with PVs knowing there own name - resolve
------------------------ Minutes ----------------------------
Present: BD, DH, MS, RL, GW, DH, NM, GS, TK
Scribe: GW
************
NEW TOPIC: Action Items
************
MS: yes, all repos were tagged.
************
NEW TOPIC: easyPVA review / Test results
************
Test Results: No, noone ran EasyPVA
GW: There are talks at the meeting (Monday)
************
AI on GW by next meeting. to test EasyPVA
************
GS: Do we have a meeting next week
BD: Suggests we do.
GW: Meeting as usual next week. (Just without BNL people.)
************
NEW TOPIC: Issue of Definition of a Structure
************
RL: Didn't understand the email description.
DH: Doesn't like present lovation of fieldname in Field. Move instead to a "member" object with name + field.
As well as refactor of Field, refactor also PVField.
Turns out it would be a lot of work.
We're converging on same solution only difference is grouping Field and Field-name into a single object (DH), rather than 2 arrays(MK).
MK: Reply to this prop in email today.
MK: Difference between DH and MK is "structure of arrays" (MK) and "array of structures" (DH). structure of arrays is simpler.
DH: Yes, but natural OO approach is structure as object, with its own interface. OO system eases burden of keeping names and values straight.
If we're that concerned about overhead, there are many places where this inversion would be appropriate.
GW: Physicists don't care too much about the beauty of the interface definitions. The "structure of array" approach seems more appropriate for our users and more efficient in its implementation.
DH: not convinced, but will accept that the implementer (MK) decides.
DH: Will top fieldName disappear?
MS/MK: Yes
DH: Structure name of StructureArrays now goes?
MS/MK: Yes
DH/GW:
MK: Im ignoring de/serialization issues for now, is that ok for MS to pick up?
MS: Yes, that's fine.
************
RESOLUTION: The definition of Structure's with respect to introspection interface and
FieldName, will be as designed in proposal by Marty. That is, FieldName moves from Field to Structure, and Fields and FieldNames will be accessible from the Structure object (as arrays).
************
http://epics-pvdata.sourceforge.net/alpha/pvDataPVAccessChanges.html
public interface Field {
Type getType();
void toString(StringBuilder buf);
void toString(StringBuilder buf,int indentLevel);
String toString();
}
public interface Structure extends Field{
Field getField(String fieldName);
int getFieldIndex(String fieldName);

String[] getFieldNames();
}
************
NEW TOPIC: How much work to get pvIOC working on VXWorks?
************
MS: Find all modules are written the way they should be for VxWorks.
.. we use sourcy?? layer.
GS: When tried to compile on RTEMS we found an error complaining that Thread Name was already in use.
GS: Now [] compiles, but doesn't load - or run.
MS: We need to do continuous integration on VxWorks and RTEMS as well as others.
TK: Dirk is now starting to look into these things.
TK: Detail that's not clear:
Which parts are needed?
MK: Ans std::tr1 - the shared pointer interface.
We do not require Boost as such, we only require std::tr1?
To compile and run EPICS V4 pv* core modules, on VxWorks v6, you must have:
Example: for the target of running PVAS on a v3 ioc, what are the system and tool requirements:
VxWorks 6.01 through 6.65
Which versions of EPICS base?
std::tr1::shared_ptr from http://gcc.gnu.org/gcc-4.0/changes.html version 4.0
Which version of GCC?
************
AI on MS: Answer what is the list of pre-requisites for compilation, loading nd execution of
pv* core modules on VxWorks 5 and VxWorks 6. Also on version.h file requried actions.
************
RTEMS IOC compilation and test will be done after vxWorks.

gethist
Usage: gethist [OPTIONS] channel
gethist [-h|--help]
see gethist --help for details
Options
Mandatory arguments to long options are mandatory for short options too.
-h,--help display help
-s,--start=START_TIME query archive for results starting from START_TIME
-e,--end=END_TIME query archive for results up to END_TIME
-f,--file=FILENAME output results of archiver query to file named FILENAME
-n,--title print channel name, preceeded by #, before results
-x,--scientific results of archiver query request outputted using
scientific (i.e. exponent/mantissa) format
-d,--fixed results of archiver query request outputted using
scientific (i.e. exponent/mantissa) format
-o, --fields specifies which fields to output, in which order
-p,--precision=PREC results of archiver query request given to precision PREC
Default value is 6.
Description
gethist queries the Channel Archive Server for the data for the channel specified
by channel argument between the -s,--start and -e,--end flags. The format
for the start and end parameters is that of the date -d command. The defaults
are "1 hour ago" for start and "now" for the end.
The data returned by the archive server is outputted in columns, formatted
according to the -x,--scientific, -d,--fixed and -p/--precision options.
For the fixed option, the precision specifies the number of decimal places. For
scientific it specifies the number of decimal places of the mantissa. The default
is neither scientific nor fixed formatting. In this case the value is formatted as
fixed or scientific, the format being value-dependent.
If the -n,--title option is selcted the channel name, preceeded by'#', is outputted
before the archived values. If the -t,--header option is selected the column name,
preceeded by'#', is outputted before the values.
The choice of fields and the order in which they are outputted can be selected by the
-o,--field option. The argument for this option consist of a sequence of characters
representing the possible fields
t floting point time, in seconds, past EPICS epoch
v the archived value
D the date and time string of the archived value
A A string based on the alarm status and severity
s seconds past UNIX epoch
n nanoseconds
S The alarm status, as an integer
V The alarm severity, as an integer
Output by default goes to the standard output along with any logging information.
It can be directed to a file using the -f,--file option. Logging information
will still be outputted to standard out.

To summarize macros briefly, a macro is like a function that generates Lisp code, which is then substituted in place of the macro. The first phase of macro processing is macroexpansion, in which the macro generates an expression. The second phase is evaluation, in which the generated expression is evaluated.
arc> (mac foo () (prn "macro executed") '(prn "generated code executed")) #3(tagged mac #<procedure>) arc> (foo) macro executed generated code executed "generated code executed"The macro foo does two things: it prints "macro executed" when it is executed during macroexpansion, and it returns the list:
(prn "generated code executed")
. When that list is executed in evaluation, it will display "generated code executed". (Since prn
returns that string, the string is also displayed a second time as the result of the command.)
Howerver, the two phases of macroexpansion and evaluation can be separated in time. If we use the macro inside a function definition, things get interesting:
arc> (def bar () (prn "bar executed") (foo)) macro executed #<procedure: bar>Macroexpansion takes place above, but evaluation of the generated code does not take place; the generated code becomes part of
bar
. This is demonstrated by the prn
statements, which show that only the macro itself is executed. Next, the macro itself can be destroyed, to illustrate that it is not necessary for the evaluation phase:
arc> (= foo nil) nilFinally, evaluation can take place. If procedure
bar
is executed three times, note that the body of bar
is executed, as well as the code generated by foo
during macroexpansion:
arc> (repeat 3 (bar)) bar executed generated code executed bar executed generated code executed bar executed generated code executed nilThis illustrates the two phases: first, the macro is executed and generates code during macroexpansion. Second, the generated code is executed, potentially much later, during evaluation. Note that the macro itself does not take part in the second step. In the example above, the macro has been destroyed. A more subtle issue is if the macro definition is changed, these changes will have no effect on previous callers of the macro; this can lead to confusion, when the old version of a macro appears to be active.
Another important difference between macros and functions is the arguments to a function are evaluated before passing them to the function, while the arguments to a macro are passed unprocessed. This is vital for macros that execute their arguments multiple times (e.g. repeat
), macros that execute their arguments conditionally (e.g. and
), and macros that process their arguments (e.g. =). To see the difference, note that the function receives the result of evaluating (+ 1 1)
, while the macro receives the list (+ 1 1)
:
arc> (def f args (prn args) nil) #<procedure: f> arc> (mac m args (prn args) nil) #3(tagged mac #<procedure>) arc> (f (+ 1 1)) (2) nil arc> (m (+ 1 1)) ((+ 1 1)) nil
Like functions, macros support destructuring bind on the arguments. Despite its intimidating name, destructuring bind is simply means that the list of parameters can be a complex nested list. The arguments passed in will be "destructured" and mapped onto the parameter list. For example:
arc> (mac db (a (b c d) e) (prs a b c d e) nil) arc> (db 1 (2 3 4) 5) 1 2 3 4 5Note that the list
(2 3 4)
has been destructured and mapped onto individual arguments. In a more complex example, note that the expressions are unevaluated, expressions can be destructured, and any extra arguments are discarded.
arc> (db (+ m n o) (+ p q r) (+ s t u)) (+ m n o) + p q (+ s t u)
Now that the phases of macro processing are clear, these phases can be illustrated in Arc.
ac.scm
foundation, but is implemented in arc.arc
out of annotated functions.
A macro can be generated "manually", illustrating the steps. Create baz
, which is like the macro foo
above, except it is a function and not a macro. Note that when executed, it returns the generated code:
arc> (def baz () ((prn "macro executed") '(prn "generated code executed")) arc> (baz) macro executed (prn "generated code executed")To turn this function into a macro, it is simply annotated as type
'mac
.
The resulting mbaz
functions exactly like the macro foo
:
arc> (= mbaz (annotate 'mac baz)) #3(tagged mac #<procedure: baz>) arc> (mbaz) macro executed generated code executed "generated code executed"To summarize, any function that generates Arc code can be annotated as type
'mac
, and the result is a macro. The annotation process is the key to forming a macro. There is nothing special about using mac
to create a macro; it is just a "convenience" macro that performs this annotation. The fact that mac
is a macro may seem circular, but since it is implemented using annotate
directly, there is no circularity.
The annotate
function provides a general typing system. It is implemented in Scheme by ar-tag
, which creates a Scheme vector of length 3: 'tagged
, the type, and the contents. For macros, the type is 'mac
, but annotate
supports arbitrary types. (For detailed background on annotate
, see Some Work on Arc.)
The internal representation of a macro as a vector can be seen by entering a macro name:
arc> do #3(tagged mac #<procedure>)
Because macros are implemented by functions, the body of the macro is initially processed by ac-fn
. A simple function is turned into a Scheme lambda function, while a function with complex (destructuring) arguments is processed by ac-complex-fn
. The destructuring is implemented by inserting the appropriate combinations of car
and cdr
to pull each argument out of the list. In other words, destructuring is just syntactic sugar; the same effect can be obtained by manually using car
and cdr to extract each argument from a rest argument.
The net result is that a Arc macro becomes an Arc procedure, tagged as 'mac
. Internally, the macro is a Scheme vector, with the third argument a Scheme procedure that will take the macro arguments, perform any necessary destructuring, and execute the macro code.
ac
. (See Arc Internals, Part 1 for background.) Code of the form (foo ...)
is passed by ac
to ac-call
. If the first argument is a macro (i.e. a vector tagged with 'mac
), it is evaluated by ac-mac-call
, which evaluates the macro function on the arguments, and then passes the macroexpanded result to ac
to be converted to Scheme. The net result is the code generated by the macro gets treated as if it were part of the original expression being processed.
Comparing ac-mac-call
to ac-call
shows why macros receive their arguments unevaluated. ac-mac-call
applies the macro function to the arguments, while ac-call
maps ac
on the arguments before applying the function, causing the arguments to be evaluated.
arc-eval
calls eval
on the Scheme code generated by ac
. It may use ar-funcalln
to execute functions, and execution will typically bottom-out with foundation operations implemented in native Scheme. (See Arc Foundation Documentation for details.)
macex
and macex1
functions perform macro expansion. If the outermost form is a macro, macex1
expands it once, while macex
expands it repeatedly until it is no longer a macro. These functions are typically used for debugging, to see what a macros is doing. Note that neither macex
nor macex1
expand inner macros.
arc> (macex1 '(or 1 2 3)) (let gs2418 1 (if gs2418 gs2418 (or 2 3))) arc> (macex '(or 1 2 3)) ((fn (gs2419) (if gs2419 gs2419 (or 2 3))) 1)
The macex
and macex1
functions are
implemented by ac-macex
, which, if passed a macro expands it. Expansion is done by applying the macro function to the arguments. For macex
, ac-macex
calls itself recursively, terminating when the outer call is no longer a macro. However, macex1
passes a 'once
flag to ac-macex
, so only one step of macro expansion is performed.
The set
special form takes a symbol and a value, and sets the variable indicated by the symbol to the value. It is implemented by ac-set
, which uses ac-macex
. This ensures the first argument to set
is a symbol, or a macro that macroexpands to a symbol. Note that something (other than a macro) that evaluates to a symbol is not permitted as the first argument to set. Thus, macro processing for set
uses a separate path from the rest of Arc's macro processing.
In conclusion, Arc's macro processing is implemented relatively straightforwardly. The biggest surprise is the representation of macros as tagged procedures, which are implemented as vectors. Macros may be somewhat nonintuitive, but understanding the internal implementation may help with writing and understanding code that makes use of macros.

Taapsee Pannu was asked to speak in Hindi at an event. Her sassy reply won the day
Taapsee Pannu gave an apt reply to an attendee who asked her to speak in Hindi at an event in Goa.
Taapsee Pannu is among those actresses in the industry who don't shy away from stating their opinion in public. In the past, the Game Over actress has shut down trolls like a boss and she continues to do so till date.
Recently, Taapsee was invited as a speaker at the International Film Festival of India in Goa. While she was interacting with the audience at the event, Taapsee was interrupted by a guest who asked her to speak in Hindi as she is a Hindi film actress. Taapsee replied saying, "Sir, main to pura Hindi me baat karsakti hoon, par kya yahan sabko Hindi samajh aayegi?"
She added, "Main south Indian actress bhi hoon... Tamil aur Telugu main bhi baat karu?"
The crowd cheered for Taapsee soon after she gave a befitting reply to the guest. The video of the actress shunning the guest has gone viral.
Not just at the event, Taapsee even slammed a Twitter user who wrote, "Kyuki Hindi elite nahi banate na." Taapsee replied saying, "Elite bhasha nahi, soch banate hai."
Taapsee was last seen in Saandh Ki Aankh with Bhumi Pednekar. The film didn't do well at the box office. The year 2019 has been a mixed bag for Taapsee. Her another film Mission Mangal, a multi-starrer, was super successful at the box office. Taapsee also starred in Game Over. The film failed to do well at the box office but Taapsee was hailed for her performance in it.
Watch the trailer of Saandh Ki Aankh:
With each performance Taapsee is solidifying her ground in the film industry. Her unabashed behaviour has also helped her stand out among her contemporaries.

java.lang.Object com.numericalmethod.suanshu.stats.cointegration.CointegrationMle
public class CointegrationMle
Two or more time series are cointegrated if they each share a common type of stochastic drift, that is, to a limited degree they share a certain type of behavior in terms of their long-term fluctuations, but they do not necessarily move together and may be otherwise unrelated.
This class implements the Johansen method to estimate the cointegrating factors.
The Johansen test, named after Søren Johansen, is a procedure for testing cointegration of several I(1) time series using MLE. This test permits more than one cointegrating relationship. It is more generally applicable than the Engle–Granger test.

Side by side with:
July 7, 2009
How you did side with stormy weather
and how stormy it did get
how you did not bear me there to betray me
just brought me to your stormy side
So by side with, uproar, outcry-
There where I hope the meter changes-
each word sounding takes a long time
may smooth lips sing them
yet be all our understanding is so different
So, be different! those words-
complete endless circles if you want to
lay descriptions like to stones
lay epitaphs in people, names and places
Yet know, those words, be careful how you say them
take care with how you cast your words out
be it that you lay them in stone names or
vicious circles, in philosophy.
When some day will rise a difference
between what is said and what is undone confusion
and then when least expected, it will all change
unless reduced to ashes, someday the words
will mean something different how we speak and say
[when our world is different]
So I -side by side with stormy weather-
wonder where the wind -does take me
out to go and watch the tense rain-
walk out over earth-en washed
and that is just the speaking part of me
Not chaos will weather ever be
never what is chaos
and though no more we know it to be
So, but why not let life feel like chaos and
-lend not that description of the other to the weather
That belief is too far to be predicated by another
so by side with another
that is chaos- and was not in the weather
but is one single storm and evening
So too forth will it be a fixed point
The storm and me
Who be that storm? what it is made of cannot be let go of


me

SC eyes solution of judge’s slay
by Hector LawasAuthorities will look into the two drugs cases which slain Ilocos Sur regional trial court Judge Mario Anacleto Bañez handled in an attempt to solve his senseless murder.
Chief Justice Diosdado Peralta bared this during his first Meet the Press event at the Supreme Court yesterday morning, saying these cases could be the reason why he was assassinated.
Peralta continued that Bañez’s dismissal of a murder case against a Cordillera health worker as motive was very unlikely.
Last September, Bañez acquitted Cordillera health worker Rachel Mariano of murder.
Mariano was accused by the army as a New Peoples Army (NPA) rebel who masterminded an ambush of members of the 81st Infantry Battallion in 2017 in Quirino, Ilocos Sur, where one soldier died.
In his decision, Bañez condemned the killing, but said: “It would be more deplorable and unfair to convict the accused of all these serious crimes charged against her upon the quality of the evidence adduced by the prosecution.”
