**Historical Context**

During World War II, Allied intelligence faced the challenge of estimating German tank production. This led to the development of statistical methods that significantly outperformed traditional intelligence gathering.

Here's how the simulation works:
1. We have a secret number of tanks (500 in this case).
2. We pretend to "capture" 5 tanks and look at their serial numbers.
3. Based on these 5 numbers, we try to guess the total number of tanks.
4. We repeat this process 1000 times to see how good our guessing methods are.

Here's the strategy:
- The "Simple" method (MLE): We just use the highest number we see.
- The "Smart" method (Unbiased): We use a slightly more complicated calculation that tries to account for the tanks we didn't see.

Observations:
1. The "Simple" method (blue) tends to guess too low. Its average guess is about 416 tanks, which is less than the real 500.
2. The "Smart" method (orange) does better. Its average guess is about 498 tanks, very close to the real 500!
3. But notice how the orange bars are more spread out. This means the "Smart" method can sometimes be way off, even though it's better on average.
4. The "Simple" method is more consistent (the blue bars are more bunched together), but it's consistently too low.

**Estimation Methodology**

**1. Basic Maximum Likelihood Estimator**

The simplest approach uses the maximum observed serial number (m) as an estimator:

N̂ = m

While simple, this estimator is biased low, as P(N̂ ≤ N) = 1.

**Improved Estimators**

**Sample Maximum Plus Average Gap**

A more sophisticated estimator adds the average gap between observed serial numbers:

N̂ = m + (m - k) / k

Where:
- m: maximum observed serial number
- k: number of observed samples

This can be interpreted as the maximum plus the average gap, providing a less biased estimate.

**Derivation from Order Statistics**

The estimator can be derived from order statistics. For a sample of size k from a uniform discrete distribution on {1, ..., N}:

E[m] = N * k / (k + 1)

Solving for N yields the unbiased estimator:

N̂ = m * (k + 1) / k - 1

**Probability Analysis**

The probability of observing a specific set of serial numbers {s₁, ..., sₖ} given N tanks is:

P({s₁, ..., sₖ} | N) = k! / (N * (N-1) * ... * (N-k+1))

Maximizing this probability (or its logarithm) with respect to N yields the maximum likelihood estimator.

Hot take: IITians are nothing but a cesspool of entitled bunch who think they are elite. An outdated classist notion of them being successful, whoever filters on the IIT tag will lead their company to utter annihilation.

Applied to Paypal through a linkedin job post around mid May. Got reached out by their HR late in May for an Online Assessment round on Hackerrank.

OA was of 1 hour and contained 8 MCQ on Android and 2 DSA easy level leetcode - 2 sum + max profit.

Cleared that and 2 WEEKS later got asked to interview for a subject in depth and DSA round.

This round contained general Android knowledge and in depth language awareness questions(Kotlin based).
Around the end of the interview, the interviewer asked to open any preferrer IDE and share the screen and then to write a solution for eliminating a target value from Integer array(can contain duplicates too) without using extra space.

Cleared that and went on to the 3rd round three days later which was essentially a repeat of the previous round but more conversational. The time ran out before any DSA Question could be asked.

Three days later got asked to interview for the Hiring Manager round which got scheduled and then got cancelled a day before the interview was supposed to take place. 

Tabse leke ye haal hai. HRs are ghosting and seem clueless themselves. Their workday portal also has removed the link for the role I was interviewing for.

Who else has been through this haath ko aaya mooh na laga situation?

Created a Quantum Circuit that implements Bernstein Vazirani algorithm to find a secret binary substring faster than a classical computer. 

Essentially, if there is a secret substring S then it will take |S| tries for a classical computer to guess it. 
But using Bernstein Vazirani Algorithm does it in a single try.

So, for a secret substring 1001, on a 4 qubit quantum computer, we can do a single shot computation and arrive at the string which was not seen by the circuit. 

Bernstein Vazirani algorithm gets the secret substring exactly as 1001 in ~636 out of every 1000 times. The erroneous values in the histogram for other possible combinations, our original secret substring was 1001, but we can also see that 0000, 0001 …. 1111 were also computed in a few cases, this error seen in the histogram is due to the quantum computing error.

Listen folks, you should totally work 70 hours over two weeks. Most of you do already. 

If you factor in lunch and some tea breaks that you normally take during the course of the day, the most productive hours you put in are about 7 hours a day for 5 days a week. So 70hrs is totally doable. 

Prove me wrong.

Working 70 hrs should be the norm

Do you have guesses on the identities of GV accounts?

Everyone needs a working code in the first attempt and that two proper and optimised. 

But DSA round I believe comes with luck based factor. You need to be lucky enough to get a question which you have done or seen before. 

Or have yourself updated with each structure and almost every type of problem. 

Fucked up and interview today.

Why is there nothing beyond DSA?

One of my friends recently started learning programming(ofc Data science) and he asked me a few questions about creating good projects for his resume. While having this conversation, we were talking about how to effectively debug the code. I asked him to check for solutions from the stack overflow, and instead he asked me,

“What’s Stack Overflow?”

Then I asked him how would he resolve the errors when he run into them and he said

After seeing current placement stats of top IITs, even after Day6 not even 50% of the batch is unplaced can we say that 2024 is the unluckiest batch?

Students with good CGPA, having internships in reputed internships are not getting placed. It's worse for mediocre students.

What are alternativev for these unplaced students?
