Have you ever worked with pipelines in Laravel?!

Probably you have heard it while having an interview?

It has lots of use cases and one of its usage is middleware implementation in its kernel.

I'm going to write about pipelines and its design pattern.

thread 🧵

 1/8

First of all Pipelines in Laravel are implemented based on chain of responsibility design pattern.

In chain of responsibility which is a behavioral design pattern we pass data to receivers and this receivers implement a specific interface that has a handler method.
2/8

Handler methods may deal with the passed argument and pass it to the next handler.

read more about the design pattern here :

https://t.co/XrJKXecyTv

Let's go for the main part :
3/8

Imagine we want to implement a twitter bot that gets some tweets around the trends and filter the words that we don't wanna show finally send as a new tweet from our bot.

About the filtering part, if it was me, I would implement it with pipelines.

Why?!
4/8

Currently I know exactly what words should be filtered but what about the future?! What if I want to add more filters, I will have to modify the source code and add more switch, if else statements, etc.

I want my code to be robust and maintainable keeping SOLID principles.
5/8

So I'm gonna use pipeline like this (picture) :

First I will have my initial filters and also give the ability to myself or other developers to add more filters without even seeing the code.

See the picture and lets go deeper and check the main interface and pipelines 😎
6/8

I have defined a contract for all of my filters, every new filter and existing filters must implement this interface and implement the filter method

As you can see in the previous picture we gave our method name "filter" passed to via()

Nothing more let's go for filters
7/8

This is one of the filters we have implemented as you can see everything is clear filter method gets an argument called $content which is the text we wanna filter and when we modify the content and remove bad words it calls the next receiver from pipelines filters we defined
8/8

That's it all.
This is the pipeline design pattern we have in Laravel.

As you can see there are a lot of advantages using this design pattern having SOLID standards.

But sometimes it's better to keep things simple when our program is not that big and you are alone...

#Suven – Journey of my first 50 bagger…

I bought #Suven first in Apr 2013 around Rs 20…today after almost 7.5 years, its Rs 1000 (Suven pharma 920 adjusted for bonus + Suven Life 80)..CAGR of almost 68% for 7.5 years. I am fortunate to hold it throughout the journey and

1/n

add on multiple occasions on way up. Like to share my experience in this thread for everyone’s benefit..

First time I bought because I like the management focus on R&D. It had chosen the most difficult therapeutic area in pharma which is CNS and it was investing the cash

2/n

flow it used to earn from CRAMS. It also used to write off all the R&D expenses in the P&L instead of capitalizing it in BS. That gave me lot of comfort about management quality.

I kept on adding as funds keep coming. I remember giving a public presentation on Suven in

3/n

Mumbai at one analyst meet in Nov 2017 when it was trading at Rs 160. There was a huge call option embedded at that time in the form of SUVN-502. That would have been the blockbuster molecule if succeeded with market potential of $10 Bn plus..result was due in Dec 2019,

4/n

I loaded around 250-300 knowing the value of CRAMS business itself is more than 300.

SUVN-502 failed in phase-II trials, stock was down 15% from 300 to 250 in a single day, I added heavily. it was largest allocation in my portfolio because I knew the value of CRAMS business

The ten points of the Nuremberg Code
1) The voluntary consent of the human subject is absolutely essential.

2) The experiment should be such as to yield fruitful results for the good of society, unprocurable by other methods or means of study, and not random and unnecessary in nature. 2/n

3) The experiment should be so designed and based on the results of animal experimentation and a knowledge of the natural history of the disease or other problem under study that the anticipated results will justify the performance of the experiment. 3/n

4) The experiment should be so conducted as to avoid all unnecessary physical and mental suffering and injury. 4/n

5) No experiment should be conducted where there is an a priori reason to believe that death or disabling injury will occur; except, perhaps, in those experiments where the experimental physicians also serve as subjects. 5/n

Wow, Morgan McSweeney again, Rachel Riley, SFFN, Center for Countering Digital Hate, Imran Ahmed, JLM, BoD, Angela Eagle, Tracy-Ann Oberman, Lisa Nandy, Steve Reed, Jon Cruddas, Trevor Chinn, Martin Taylor, Lord Ian Austin and Mark Lewis. #LabourLeaks #StarmerOut 24 tweet🧵

Morgan McSweeney, Keir Starmer’s chief of staff, launched the organisation that now runs SFFN.
The CEO Imran Ahmed worked closely with a number of Labour figures involved in the campaign to remove Jeremy as leader.

Rachel Riley is listed as patron. https://t.co/nGY5QrwBD0


SFFN claims that it has been “a project of the Center For Countering Digital Hate” since 4 May 2020. The relationship between the two organisations, however, appears to date back far longer. And crucially, CCDH is linked to a number of figures on the Labour right. #LabourLeaks

Center for Countering Digital Hate registered at Companies House on 19 Oct 2018, the organisation’s only director was Morgan McSweeney – Labour leader Keir Starmer’s chief of staff. McSweeney was also the campaign manager for Liz Kendall’s leadership bid. #LabourLeaks #StarmerOut

Sir Keir - along with his chief of staff, Morgan McSweeney - held his first meeting with the Jewish Labour Movement (JLM). Deliberately used the “anti-Semitism” crisis as a pretext to vilify and then expel a leading pro-Corbyn activist in Brighton and Hove

Nice to discover Judea Pearl ask a fundamental question. What's an 'inductive bias'?


I crucial step on the road towards AGI is a richer vocabulary for reasoning about inductive biases.

explores the apparent impedance mismatch between inductive biases and causal reasoning. But isn't the logical thinking required for good causal reasoning also not an inductive bias?

An inductive bias is what C.S. Peirce would call a habit. It is a habit of reasoning. Logical thinking is like a Platonic solid of the many kinds of heuristics that are discovered.

The kind of black and white logic that is found in digital computers is critical to the emergence of today's information economy. This of course is not the same logic that drives the general intelligence that lives in the same economy.

RT-PCR corona (test) scam

Symptomatic people are tested for one and only one respiratory virus. This means that other acute respiratory infections are reclassified as

It is tested exquisitely with a hypersensitive non-specific RT-PCR test / Ct >35 (>30 is nonsense, >35 is madness), without considering Ct and clinical context. This means that more acute respiratory infections are reclassified as

The Drosten RT-PCR test is fabricated in a way that each country and laboratory perform it differently at too high Ct and that the high rate of false positives increases massively due to cross-reaction with other (corona) viruses in the "flu

WHY BABUR NEVER TRIED TO ATTACK SRI KRISHNADEVARAYA ?

A🧵u must read

It is very well known that Babur considered Krishna Dev Raya as the strongest ruler of the entire subcontinent, and Vijayanagar empire the strongest during that time in India.

1/10


The Vijayanagar empire reached its peak during 1509-1529 around the reign of Krishna Dev Raya.

Vijayanagar’s famed elephant brigade 👇

2/10


At his command there were over 50000 elite troops with a regiment of Portuguese gunners and 3200 cavalry with 600 elephants.

3/10

Along with that more than four hundred thousand ( four lakh) peasant levies and irregular military made this empire one of the largest in all of South Asia.

A typical Vijayanagar levie soldier 👇

4/10


During Baburs invasion, Krishna Dev Raya ruled supreme in all of deccan.

In fact, in an all our brawl, Krisha Dev Raya will beat Babur fair and square.

Babur could muster at max 50000 troops with 50 canons.

While Krishna Dev Raya had these numbers in Hampi alone

Shri Hanuman had boon to be immortal. And be present where ever there is Ram stuti.
I came across this beautiful story that I would like to share

#Hanuman ji is believed to live in the foothills of Himalayas. But once he spent a lot of time in Sri Lanka

Where Ravan's brother ruled for many years..
On his way back he came across tribal people from community called #Mathanga
He gave Darshan to them. The chief of the tribe asked him to keep coming back to guide their generations
Hanuman ji said that whoever recites this mantra

I will give them Darshan. But there are two conditions
1st he/she must know his relationship with me
2nd there must not be anyone around him in 950 mts radius. If present, that person must also know about my relationship with him /her.

He promised to come after every 41 yrs

The Mathangs also maintain a ‘logbook’ where they record all the words spoken and ‘leelas’ performed by Lord Hanuman.
They call him their Guru
Who teaches them how to live their lives.
A Sri Lankan organization called Setuu is studying this ‘logbook’ and also conduct

programmes for Hanuman devotees who can do ‘Sadhna‘ under the guidance of Setuu masters. Devotees who qualify all the criteria will be eligible for Hanuman’s ‘sakshaat darshan‘
The Setuu has certain conditions that need to be kept in mind which includes devoting one complete
