EP 5: How a Poor, Uneducated, Fatherless 4-year-old Kid Used \$22 to Build a \$12,000,000,000 Company: Rolls-Royce

Unfortunately, this interesting story didn’t have a happy ending, you may actually shed tears...

Henry Royce was born in 1863 in England to a family of James and Mary Royce. His parents ran a flour mill business, which later went bankrupt after many years of struggling to keep it alive.

This strategy made them leave for the capital city of England, London, to search for
greener pastures.

By this time Henry Royce was just 4 years old, despite his young age he tried helping his parents out by getting a small job where he scared birds off the land of a farmer for 2 cents.

While he was doing that his father, James Royce went to work for a
Twitter open sourced its recommendation algorithm and while my timeline is exploding with analysis of it; all I can think of is: what is the point?

Code without the training data is interesting but useless.

Is it a recruitment tool for devs? Promote Scala? Something else?
Or is it meant to move attention away from the surprising (and likely damaging) decision to remove the “legacy” verified check marks?

I wouldn’t mind seeing Twitter as a business/service thrive, and have no idea what this repo achieves. Outside of devs, it speaks to no one.
I am under no illusion that #TechTwitter is a small niche within Twitter. And yes, this step has interest within this community.

But for “mainstream Twitter”, celebs like LeBron tweeting daily is what brings them back. And Twitter is nudging LeBron to stick to Instagram et all:
" SQL Puzzle Interview Question "

🧵
Table script:

create table input (
id int,
formula varchar(10),
value int
)
insert into input values (1,'1+4',10),(2,'2+1',5),(3,'3-2',40),(4,'4-1',20);
" Exploratory Data Analysis on Terrorism "

🧵
We are performed Exploratory Data Analysis on terrorism #dataset to find out the hot zone of #terrorism. #EDA nothing but #analyzing the given data & finding the #trends, patterns & making some assumptions. #DataVisualization #DataScience #MachineLearning
In this #dataset, there are many features including countries, states, regions, gang names, weapon types, target types, years, months, days, and many more features.
▶️Practice Writing SQL Queries using Real
Dataset 💯

🧵
“The very first thing, we must do when writing #SQL queries, is to understand the underlying data. Once we understand the data and how this data is stored across different tables, it becomes much simpler to write SQL #Queries to retrieve any information from that data”
✅List of SQL Queries:

We shall write SQL #Queries using this data. For each of these queries, you would find the problem statement and then the screen shot of the expected output. Under each of these 20 problem statement
6 Must have line charts for business data analysis 📈👌 💯

🧵
1. Indexed chart for comparing trend
2. #Sparkline for tiny insight
3. Spaghetti line #chart for bringing focus
4. Smoothed line chart for evening out edge
5. Forecast chart to predict future value based on trend & seasonality
6. Line chart combination when just a line won't do
▶ Line charts are similar to #scatterplots except that they connect the data points with lines. Choose a line chart when ordering and joining the #data points by their X-axis values highlights meaningful changes in the vertical Y-axis variable.

Generator function* in JavaScript:

#100DaysOfCode #javascript #Angular #reactjs #devbubble
In JavaScript, generator functions are a special type of function that allows you to use the yield keyword to pause and resume the execution of the function.

#100DaysOfCode #NodeJS #CodeLife
They allow you to create iterators, which are objects that can be used to iterate over a sequence of values.

A generator function is defined using the function* keyword and can be invoked using the yield keyword.

Memoization: Using Proxy in JavaScript

#100DaysOfCode #javascript #rarely_used #devbubble
Memoization is a technique used to optimize the performance of a function by caching its results for a given set of inputs.

#100DaysOfCode #reactjs #Angular #NodeJS
The idea is that if a function is called multiple times with the same input, it's more efficient to return the cached result instead of re-computing the result each time.

#100daysofcodingchallenge #reactjs #Angular #NodeJS
Data virtualization: With Proxies in JavaScript.

#100DaysOfCode #javascript #rarely_used #devbubble
Data virtualization using Proxies in JavaScript refers to the ability to create virtualized data structures, such as virtualized arrays, that load their data on demand rather than loading all data at once.

#100DaysOfCode #ReactJS #Angular
This can be useful for improving the performance of an application when working with large data sets.

In this Eg., we create a VirtualArray class that takes in two args- the length of the array & a loader function.

WeakMap in JavaScript

#100DaysOfCode #javascript #rarely_used
A WeakMap is a map that holds weak references to its keys.

This means that the keys are eligible for garbage collection if there are no other references to them.

This feature can be useful for implementing caches or other similar data structures.

#reactjs #Angular #NodeJS #js
A WeakMap is a special kind of map where keys must be objects and the map doesn't prevent garbage collection of its keys.

You can think of a WeakMap as a map that doesn't "own" its keys, and therefore doesn't keep them alive.

Today's lab consisted of testing a theory from my @Fortinet NSE4 and NSE5: To connect FortiGates to FortiManager and FortiAnazyler from across the WAN using a VIP.

Mapping a specific IP address to another specific IP address is usually called Destination NAT (DNAT). FortiOS calls this a Virtual IP address (VIP). DNAT, or VIP, is are used to map an external IP address to an IP address or address range.
The mapping can include all TCP/UDP ports or, if port forwarding is enabled, it only refers to the specific configured ports.
I’m a 15-year-old web designer and I love what I do. In 3 years, I would have worked on several live projects with top IT companies.

I developed an interest in developing websites from a very young age.
I’m excited about where I will be very soon and my advice for young children is to acquire a skill because we all are now in a digital world that is characterized by fast-paced, technology-driven social change.
The future will be full of tremendous opportunities which we need to prepare for. Please learn a skill.#techtwitter

A few months ago, I got a promotion at #Meta with a \$50K raise.

I immediately updated my resume b/c I knew I was worth more than that.

I landed a job at #Google that increased my compensation by over \$150K.

Tech is one of the few industries where women and BIPOC can be compensated fairly without going to war with their colleagues and bosses.

That kind of stress will take years off of your life. (Google: Racism as a public health issue.)
So, how did I know that I was worth more?
By using resources like Levels.fyi and TeamBlind.

This is a role where you will engage w/ clients of your company to capture current engagement and usage, goals, & together determine how your company’s products & services may support in driving their goals & priorities & leverage your company tools to scale their team or brand
Customer Success is sometimes referred to as client success, customer experience or client partner. The main objectives are to onboard and engage with existing customers to drive customer objectives and increase customer satisfaction #techtwitter #tech #techtrends
I thought this was common knowledge by now, but software engineers at “big tech” and in some of the major tech hubs in the US makes lots of money. I’d encourage you to look at levels.fyi to see the potential earnings at these companies. #techtwitter #BlackTechTwitter
That said this is about potential. This site doesn’t show how many people exists at these levels, let alone how many underrepresented people exist at some of these levels.
At Microsoft about 5.6% (query.prod.cms.rt.microsoft.com/cms/api/am/bin…) of the population is black and I know, just by looking around that there are a lot fewer in the upper echelons of levels. The percentages are more abysmal the further up the chain you go.

Q: What is a model?

A: a simplified process that represents how networks function.

So not this diva. The other type of model.
✅There is the OSI model
✅There is the TCP model

Here's something I've been struggling with for a while.

- The word "Poach" and it's usage in Tech

I need some help from #TechTwitter. Should we stop using "Poach" at all??

1/6
As per online dictionaries, it means hunting animals illegally, in it's origin.

However, in tech, it has always meant (only for me?) to approach candidates who aren't looking for a new job, with the goal of hiring them.

2/6
For this reason, many contracts having "Anti-Poaching" clauses.

Meaning that you can't reach out to former employees/colleagues/etc to hire them. It's a standard clause along with confidentiality and so on.

Recommended Smartphone Charging Habits
- Avoid charging your phone overnight. When your phone remains at full charge for a prolonged period of time, it can affect your battery's health. Adaptive charging is recommended if you do need to charge your phone overnight, that's if your phone supports it....
If not, charge your phone during the day, or whenever you can unplug your charger when your battery is full.
