Meet the Winners of Startups in South America

It's currently 14:30, February 28th, 2023, while I'm writing this update to the challenge. I'm going to make it short. We didn't make it. We actually didn't even get anywhere close to making it. It was a complete failure of a challenge. Okay, okay, that's properly a bit too gloomy. It was kind of expected that we wouldn't make any money after the month was over. But what we didn't receive in terms of monetary gains we got in (quoting the great (scam) entrepreneur Tai Lopez) knowledge. We also decided to make some adjustments to the challenge to keep it going, let's break it down. What Went Wrong First thing first, if you attempt to do this challenge, don't select the shortest month of the year to do a 1 Month 1 Dollar challenge. That's just shooting yourself in the foot. Additionally, don't pick the same month when you've planned holidays with your girlfriend, thinking you can just do a little bit of work. Especially, don't plan two holidays in the shortest month of the year for this challenge. I'm only half joking here, but seriously, we didn't give this challenge the focus and energy it required. We should have picked another month when we both could focus, at least 40 hours a week fully on the project. Next up, and this is the biggest one, we started outreach too late. We did get some early promising results by doing (personalized) outreach on LinkedIn. I think we might have reached out to around 50 people in total which resulted in ~8 getting back to us, and out of those ~8 people, 1 wanted to jump on a call with us, showing some interest in the product. The excitement quickly died down when we discovered that the person didn't really get our value proposition. Both good and bad, we have new information we can react to, and it helps point us in the right direction. However, we didn't get any new calls or follow-ups after this. It could be due to people just being busy but I would guess more that we didn't pursue this aggressively enough. What Did We Learn There is something about learning a new skill where it only really manifests itself in your mind when you try to actually do that skill. Most of this advice is already flooded on the internet, in start-up/bootstrapping forums, etc. But, basically, it can be boiled down to: Get a landing page out there quickly | Forces you to describe your product and makes it more concrete.


Write down your assumptions from the beginning | Continuously test and adjust them to new information.


Reach out to people even when you have a half-baked notion of your product. The first two points are pretty self-explanatory; if you're not sure what is meant by point 2, check out the original post. I do think the third point is the main learning from this challenge. You got to focus on what actually moves the needle and pushes you towards a profitable product, which means getting people to give you money. It's extremely comfortable to just build build build (especially as software engineers) while having wet dreams about all the monthly reoccurring revenue you're going to receive in the end. But that is, on average, not really a productive strategy even though it might feel like it. Sure, all your assumptions could be spot on and your big-bang release is going to be a raving success. Most are just not. So, speak to more people, look up people in relevant positions/groups on LinkedIn, find people following your competitors on Twitter, scour those Facebook groups, and write to people. Also, make sure to read The Mom Test. A Blank Piece of Paper Was it all bad and with no successful experiences? Not at all, one process that really helped us kick this off was the habit of continuously writing down ideas each day. There is something strange about the blank page effect; it can stare about at you for hours on end, almost paralyzing your ability to get started. Should I start with X? Should I include Y? But what about that incredibly important Z? It's seriously frustrating, and it was something that both Rasmus and I were feeling a bit anxious about before starting the project. For the past ~2 months, we have been meeting up once a week to discuss ideas, problems, businesses, and everything under the sun related to bootstrapping companies. I myself had been trying to (and somewhat succeeding) write down 10 ideas a day, and you quickly come to realize: ideas are not that hard to get. It's definitely a muscle that can be trained with consistency just like, well, pretty much anything. Most of that comes out as dog shit, like my brilliant idea of uber but for walking dogs - list where you want to go, and a dog will walk there with you, not exactly a Zero to One idea. It did give us a list of 200+ ideas to start from, which means, 200+ ideas that can be combined, modified, thrown away, or lead you down new paths to even better ideas. The tiniest bit of exploration sparked new ideas which led us to ask new questions that we hadn't considered before. You do see this a lot on forums like indiehackers where people, on a quite consistent basis, will be asking how people generate ideas. And every time, you will see the same (more or less) generic advice: solve your own problems
look for problems at work/with clients or what issues are your friends having These never worked well for me, mainly because I forgot to actually think about these things while doing my work. So, it felt like nothing was actually occurring to me, and I was left with no viable product ideas, and therefore, didn't really build anything. Making a habit out of writing down 10 ideas a day did work, however, so if you're struggling with this give it a try. You'll soon start thinking about potential products consistently. Change of Direction Is it over? No, but we're making some adjustments. It will no longer be a 1 Month 1 Dollar challenge but instead: 1 Year 1 Noodle. This is basically just to say that the challenge will continue in the sense that we will keep trying to get our hands on that sweet magical internet money. And then post an update once in a while. We'll continue working on the product for the foreseeable future until we either get some traction or kill it; it's definitely too early to kill it. If you want to check it out, it can be found here databayz. Outside of the challenge, I have also been working on another project to help do customer discovery on Reddit: This Week On Reddit. The process for this is going to be roughly the same as described above, outreach outreach outreach. But more on that in a later post.

One Month One Dollar - Part 2: What Went Wrong

In the wake of the global IT outage, today’s events have suddenly brought into sharp focus the latent vulnerabilities within our interdependent digital infrastructure. Chaos has gripped airlines, healthcare, and financial institutions—critical services. Right at the centre of this crisis lies a flawed software update by security firm CrowdStrike that aimed to protect Microsoft Windows devices. These consequences thus serve as a shocking reminder of the risks involved with the forcing updates strategy Microsoft uses and its high dependency on a few key players within the technology world. The Extent of the Chaos The CrowdStrike update disruption was highly significant. Carriers like United, Delta, and American Airlines grounded flights worldwide, causing long queues and delays at airports. At Sydney, Tokyo-Narita, and Delhi airports, it was reported that the departure screens had gone blank at some of these locations, while in Europe, there was a huge delay noted at London's Stansted and Gatwick and Amsterdam's Schiphol. Ryanair issued a warning regarding possible disruptions resulting from a third-party outage. It also had an impact on the health sector: In the UK, GPs were having issues making appointments with patients. Financial and retail sectors were equally hit—supermarkets like Morrisons and Waitrose didn't handle contactless payments, forcing many to go back to cash-only transactions. The same happened in Australia's National Australia Bank and retail chains like Woolworths. The Root Cause: Forced Updates The outage had been triggered by a "defect" in a content CrowdStrike had provided for a Microsoft Windows update. As stated by CrowdStrike's CEO, George Kurtz, this was not a security incident or cyber-attack but rather a flawed update. By the time it was identified that there was indeed a problem and that Crowdstrike had isolated the issue, the damage was done. The fix needed to be applied individually at each affected device by manually entering safe mode—a huge logistical challenge for IT departments everywhere. This incident highlights the dangers of forced updates Microsoft applies that have been inherent in it. As much as updates are meant to enhance security and functionality, automatically pushing them without proper testing may lead to catastrophe. Forced updates take away the power from users and IT administrators regarding when and under what conditions changes in software occur, hence raising the possibility of issues on a bigger scale. The Vulnerability of Centralized Systems CrowdStrike's involvement in this outage is revealing of something deeper: the fragility of centralized systems. CrowdStrike is a relatively young company that forms one of the hinges on which cybersecurity for many large organizations turns. That type of fast growth and wide adoption is both a tribute to its capabilities and a possible single point of failure. The recent outage shows how an issue in one part of the huge network can turn into a global crisis. Microsoft's role in the situation is equally critical.

This allows any problems originally detected to be resolved within a controlled environment. Microsoft needs to revise its forced update policy, which all too often disrupts users and businesses by forcing potentially flawed updates with little notice or control. Microsoft should instead enable rollbacks to a previous release and phased rollouts that allow updates to be tested on a smaller subset of users before a wider release. This would, in turn, open up the opportunity to identify problems earlier than usual and fix them prior to their causing wide disruptions—to improve overall stability and reliability in software. It would be a nice enhancement to user experience and improved faith in the Microsoft ecosystem if this empowered users and IT administrators to feel better toward updates. The flawed CrowdStrike update and the subsequent universal IT outage remind us how fragile our digital infrastructure really is. It underlines the risks that come with forced updates and the vulnerabilities in centralized systems. As we grow ever more dependent on digital technologies, ensuring that solid, reliable, and transparent cybersecurity practices have never been more opposing. The CrowdStrike and Microsoft companies will indeed have to learn from the saga and put in place proactive measures to prevent such events in the future. In the wake of the global IT outage, today’s events have suddenly brought into sharp focus the latent vulnerabilities within our interdependent digital infrastructure. Chaos has gripped airlines, healthcare, and financial institutions—critical services. Right at the centre of this crisis lies a flawed software update by security firm CrowdStrike that aimed to protect Microsoft Windows devices. These consequences thus serve as a shocking reminder of the risks involved with the forcing updates strategy Microsoft uses and its high dependency on a few key players within the technology world. security The Extent of the Chaos The CrowdStrike update disruption was highly significant. Carriers like United, Delta, and American Airlines grounded flights worldwide, causing long queues and delays at airports. At Sydney, Tokyo-Narita, and Delhi airports, it was reported that the departure screens had gone blank at some of these locations, while in Europe, there was a huge delay noted at London's Stansted and Gatwick and Amsterdam's Schiphol. Ryanair issued a warning regarding possible disruptions resulting from a third-party outage. It also had an impact on the health sector: In the UK, GPs were having issues making appointments with patients. Financial and retail sectors were equally hit—supermarkets like Morrisons and Waitrose didn't handle contactless payments, forcing many to go back to cash-only transactions. The same happened in Australia's National Australia Bank and retail chains like Woolworths. The Root Cause: Forced Updates The outage had been triggered by a "defect" in a content CrowdStrike had provided for a Microsoft Windows update. As stated by CrowdStrike's CEO, George Kurtz, this was not a security incident or cyber-attack but rather a flawed update. By the time it was identified that there was indeed a problem and that Crowdstrike had isolated the issue, the damage was done. The fix needed to be applied individually at each affected device by manually entering safe mode—a huge logistical challenge for IT departments everywhere. This incident highlights the dangers of forced updates Microsoft applies that have been inherent in it. As much as updates are meant to enhance security and functionality, automatically pushing them without proper testing may lead to catastrophe. Forced updates take away the power from users and IT administrators regarding when and under what conditions changes in software occur, hence raising the possibility of issues on a bigger scale. The Vulnerability of Centralized Systems CrowdStrike's involvement in this outage is revealing of something deeper: the fragility of centralized systems. CrowdStrike is a relatively young company that forms one of the hinges on which cybersecurity for many large organizations turns. That type of fast growth and wide adoption is both a tribute to its capabilities and a possible single point of failure. The recent outage shows how an issue in one part of the huge network can turn into a global crisis. Microsoft's role in the situation is equally critical.

This one goes to all the backend developers who create APIs for the frontend developers and want their team to succeed, become more productive, and rock everybody’s socks. Here are a few simple things that can decrease your time-to-market or improve other fancy metrics your managers want you to improve. I will tell it from the web developers’ point of view, but from what I remember, the same works for mobile development. I will use my experience working with a guy who made perfect APIs and with whom we literally understood each other without words. Okay, yes, it was me: I used to be a full-stack dev. But I firmly believe that people can understand each other just as a frontend-me and a backend-me did. I’m not going to tell you about readability, consistency, stability, and stuff like that: you know what makes a great engineer without my advice. I want to discuss those things that will help your frontend colleagues work with your API more efficiently and ship the product with as little friction as possible. Data Structure Before Everything Most of the time, our first task is to map the data we will have to the design. And that’s where your future structure might come in handy: if you start your development with the data model, feel free to share it with the frontend devs before the actual API is ready. Because—surprise!—we start with the data model as well. Translating these interfaces into Typescript (hello, Copilot) is a good kickstart. And the devs who use pure JS, God help them all, will also benefit from knowing the names of fields. I understand that some names can change later, but it is better to fix the naming after than guess it before. This way, we can discuss and change it before it is too late. We can agree on naming and avoid having a method getUsers that calls the GET /accounts endpoint (different entity naming is painful in the long term). Moreover, we can mock the data on our side to test how different enum values and optional fields are displayed, check the edge cases and whatnot. It will be even better if you get access to Figma and create a model by looking at the result. And it’s not a typo: I suggest that backend developers have access to Figma to make the data structure that solves the actual needs of the frontend part. One Call to Rule Them All Another good reason for looking at the design at this stage is the possibility of thinking about optimizing the number of calls. In a perfect world, I’d like to have one call that shows all the visible data on the page. Of course, there might be pagination, infinite scroll, common cached data, and micro-optimizations on loading crucial parts before the rest of the page. But the primary data getter should reflect the final result. I’m not saying it’s impossible to combine the data from different sources, and I understand the situations might differ, but, in general, we want to reduce the number of calls to let the users get their data faster and make the page more robust. Once again, don’t treat it as black and white: obviously, it’s okay to have several requests if we can show the significant part quickly and then load the additional data. The rule of thumb: each API call can fail independently without breaking the UI completely; it should only make one meaningful part hidden behind the error message. The same applies to data manipulation requests. I can send patching requests for each object, but if the design suggests bulk editing, it’s nice to have one call for that. Give Us Some Data Testing the empty state is always a good idea, but frankly, when we integrate the API, we would love to see some examples of data. The more, the merrier. And by saying “more”, I also mean “more different.”  If you have direct access to the dev DB or can readily test your calls, please add a few rows with different values. At this stage, it’s better to make them look like real ones, so we can find out something that wasn’t an issue in the cozy design mockups with polished data that always fits the container. The Devil Is in the Details Do you know that feeling when you need to add a comment so your code is understandable in a week? Life happens, and sometimes, tricky things arise from the complicated requirements. If you feel that, please share the news beforehand. Of course, you don’t need to say that pressing the “Delete item” button should call the deletion route, but if there’s a twisted logic you had to make an additional method for, or if there are two endpoints that look similar, but used differently, or if there’s a parameter whose value should be hardcoded for some time, please let us know. I know this one is the hardest to master because when we work on something, we dive into the tiniest details—so it feels obvious. But it is not like that from the outside, so if you had to take an unconventional approach to this API, please don’t keep it secret. Communication Is Key Like in every relationship, the most important thing is the dialogue. I told you a few things that I find efficient, but maybe in your team, you’ll want the frontend devs to describe the endpoints beforehand. Or you have a technical product manager who can do it themselves. Or maybe your development cycle allows you to do it in a very different way. And that’s where the good old talk comes in useful. You can start with this list and then align the processes to make them comfortable for everyone. Don’t wait for the managers to do that, because you know better. But whatever works best for your team, I insist that the backend devs should treat frontend devs as users. Basically, it’s like being a product manager for the API: you can do a mediocre thing that works or create something your target audience truly enjoys using. Choose wisely.

ChatGPT: Certainly, it's a common area of confusion for many students. Let's break it down one by one, using simple analogies: 1. Atom: • Imagine an atom as a single LEGO brick. It's the tiniest piece of an element that still retains the properties of that element. Just like a single red LEGO brick represents the color red, a single hydrogen atom represents the element hydrogen. 2. Molecule: • When you connect several LEGO bricks together, you form a structure. In chemistry, when you connect several atoms together, you form a molecule. For instance, two hydrogen atoms (H) can connect to form a hydrogen molecule (H2). Similarly, two hydrogen atoms and one oxygen atom can connect to form a water molecule (H2O). ***3. Mole: *** • This one's a bit more abstract. Let's say you have a big box filled with identical LEGO structures (say, LEGO houses). If you count them and find there are exactly 6.022 x 1023 LEGO houses in that box, you have a "mole" of LEGO houses. • In chemistry, a mole is a specific number of things (atoms, molecules, electrons, etc.). Specifically, one mole of any substance contains exactly 6.022 x 10[23] of those entities. This number is called Avogadro's number. • The concept of a mole is a standardized way to talk about quantities in chemistry, much like a "dozen" is a standardized way to talk about 12 of something. So, to recap: • : Smallest unit of an element. Atom • : Made up of multiple atoms bonded together. Molecule • : A specific quantity (6.022 x 10[23]) of atoms, molecules, or other entities. Mole Do these analogies help clarify the differences for you? BingChat: I see that you are confused about the difference between atom, molecule and mole. These are three important terms in chemistry that describe different aspects of matter. Let me try to explain them to you in a simple way. An atom is the smallest unit of an element that retains its chemical identity. An element is a pure substance that consists of only one type of atom. For example, hydrogen, oxygen, carbon, and gold are elements. Each element has a unique symbol and atomic number that indicates how many protons it has in its nucleus. For example, hydrogen has the symbol H and atomic number 1, meaning it has one proton in its nucleus. Atoms are composed of subatomic particles such as protons, neutrons, and electrons. Protons and neutrons are found in the nucleus, and electrons orbit around the nucleus in shells or orbitals. The number of electrons in an atom determines its chemical behavior and reactivity [ ] 12 A molecule is a group of two or more atoms that are held together by chemical bonds. A chemical bond is a force of attraction between atoms that share or transfer electrons. There are different types of chemical bonds, such as covalent, ionic, metallic, and hydrogen bonds. A molecule can be composed of atoms of the same element or different elements. For example, oxygen gas (O2) is a molecule composed of two oxygen atoms bonded by a covalent bond. Water (H2O) is a molecule composed of two hydrogen atoms and one oxygen atom bonded by covalent bonds. A molecule has a specific shape and structure that determines its physical and chemical properties[ ]. 32 A mole is a unit of measurement that is used to count the number of atoms or molecules in a given amount of substance. A mole is defined as the amount of substance that contains as many particles (atoms or molecules) as there are atoms in 12 grams of carbon-12. This number is called Avogadro’s number and it is approximately 6.022 x 10[23]. That means one mole of any substance contains 6.022 x 10[23] particles (atoms or molecules). For example, one mole of oxygen gas contains 6.022 x 10[23] molecules of O2, and one mole of water contains 6.022 x 1023 molecules of H2O. The mass of one mole of a substance is called its molar mass and it is equal to its molecular weight in grams. For example, the molecular weight of oxygen gas is 32 g/mol and the molecular weight of water is 18 g/mol[ ]. 42 So, to summarize, an atom is the smallest unit of an element, a molecule is a group of atoms bonded together, and a mole is a unit of measurement that counts the number of particles in a substance. I hope this helps you understand the difference between atom, molecule and mole. :) *: An atom is the smallest unit of matter that still has all of the properties of its element. An element is a substance that cannot be broken down into simpler substances by chemical means.* Bard A molecule is a group of two or more atoms held together by chemical bonds. A chemical bond is a force that holds atoms together. A mole is a unit of measurement that is used to count atoms and molecules. One mole of any substance contains 6.02214076×10^23 particles of that substance. This number is known as Avogadro's constant. Here is a table that summarizes the key differences between atoms, molecules, and moles: Here are some examples of atoms, molecules, and moles: • Atoms: Hydrogen (H), helium (He), oxygen (O), carbon (C) • Molecules: Water (H2O), carbon dioxide (CO2), methane (CH4) • Moles: One mole of hydrogen atoms, one mole of water molecules, one mole of carbon dioxide molecules I hope this helps to explain the difference between atoms, molecules, and moles. Please let me know if you have any other questions. *: Excellent question! Those three terms can definitely be confusing. Let's go through them one-by-one:* Claude Atom - The basic building block of matter. Atoms are made up of protons, neutrons, and electrons. An atom is the smallest unit of an element that maintains the properties of that element. For example, a hydrogen atom has 1 proton; a carbon atom has 6 protons. Molecule - A group of two or more atoms bonded together. A molecule is the smallest unit of a chemical compound that maintains the properties of that compound. For example, a water molecule contains 2 hydrogen atoms and 1 oxygen atom bonded together (H2O). Mole - This is a number representing 6.02 x 10^23 things. It's usually used to represent a certain quantity of atoms or molecules. For example, 1 mole of carbon contains 6.02 x 10^23 carbon atoms. So in summary: • Atoms are the basic units of elements • Molecules are groups of bonded atoms that make up compounds • Moles are a way to represent 6.02 x 10^23 of something (useful for relating atomic/molecular masses to macroscopic masses) Let me know if this helps explain the distinction between these three important chemistry concepts!

Welcome, JavaScript folks! Today, we delve into the interesting world of recursion, a programming concept that can both beguile and empower coders. We'll take a look at what recursion is, talk about the building blocks of and common pitfalls, and explore when recursion shines (and when it might not). recursion 1. What is Recursion? Recursion, in essence, is a function's ability to call itself. It creates a self-referential loop where the function breaks down a problem into smaller, similar subproblems, eventually reaching a base case that halts the recursion and provides the final answer. Imagine a set of Russian nesting dolls: the largest doll contains a smaller doll, which in turn contains an even smaller one, and so on until you reach the tiniest doll. Recursion works similarly, with each function call representing a smaller version of the original problem. 2. Building Blocks of a Recursive Algorithm Here are the building blocks to build a recursive algorithm: This is the all-important exit strategy. It's a simple condition that terminates the recursion and provides the solution for the smallest possible subproblem. Without a base case, your function would call itself infinitely, leading to a stack overflow error (we'll get to that later). Base Case: This is where the function breaks down the larger problem into a smaller, similar one. It typically involves modifying the input parameter and making a recursive call with the modified value. Recursive Case: In each function call, a return statement is crucial. It sends the result back up the call stack, eventually leading to the final output. Return Statement: Let's dive into some code examples to solidify these concepts. 3a. Example #1: Summing a List of Numbers with Recursion We'll start with the example of summing a list of numbers using recursion. function sumRecursive(list) {
if (list.length === 0) {
return 0; // Base case: empty list sum is 0
} else {
const firstElement = list[0];
const remainingList = list.slice(1);
return firstElement + sumRecursive(remainingList); // Recursive case
}
}

const numbers = [1, 2, 3, 4, 5];
const sum = sumRecursive(numbers);
console.log(sum); // Output: 15 The function takes a list of numbers as input. sumRecursive The base case checks if the list is empty. If so, it returns 0 (the sum of an empty list). In the recursive case, the function extracts the first element from the list and stores the remaining elements in a new list. It then returns the sum of the first element and the result of recursively calling with the remaining list. This process continues until the base case is reached. sumRecursive 3b. Summing a List of Numbers with Iteration (For Comparison) Here's how we might achieve the same result using a loop (iteration): for function sumIterative(list) {
let sum = 0;
for (const num of list) {
sum += num;
}
return sum;
}

const numbers = [1, 2, 3, 4, 5];
const sum = sumIterative(numbers);
console.log(sum); // Output: 15 The function takes a list of numbers as input. sumRecursive We declare a variable sum to keep count of the total sum of the array. We then iterate over the list of numbers and, at each iteration, add the current number to the value of sum. Lastly, we return the value of sum. This iterative approach is generally considered more efficient for simple tasks like summation. However, recursion shines in solving problems with a naturally recursive structure, as we'll see in the next example. 4a. Example #2: Fibonacci Sequence with Recursion The is a famous mathematical series where each number is the sum of the two preceding numbers (except the first two numbers, which are typically defined as 0 and 1). Let's see how recursion tackles this problem: Fibonacci sequence function fibonacciRecursive(n) {
if (n <= 1) {
return n; // Base case: 0 or 1
} else {
return fibonacciRecursive(n - 1) + fibonacciRecursive(n - 2); // Recursive case
}
}

const number = 6;
const result = fibonacciRecursive(number);
console.log(result); // Output: 8 The function takes an index as input, representing the position in the Fibonacci sequence. fibonacciRecursive n The base case checks if n is less than or equal to one, which accounts for 0 being 0 and 1 being 1 in the Fibonacci sequence If we aren't in the base case, we go off of the definition of the Fibonacci sequence by calculating the intermediate sequence of n - 1 added to n - 2 4b. Example #2: Fibonacci Sequence with Iteration (For Comparison) function fibonacciIterative(n) {
// Handle negative or zero input
if (n <= 0) {
return 0;
}

// Initialize first two Fibonacci numbers
let a = 0;
let b = 1;

// Iterate n-1 times (since the first two numbers are already defined)
for (let i = 2; i <= n; i++) {
let c = a + b;
a = b;
b = c;
}

// Return the nth Fibonacci number
return b;
}

// Example usage
console.log(fibonacciIterative(6)); // Output: 8 Alright, we've reached the halfway point in our exploration of recursion in JavaScript. If your mind is a little blown right now, that's perfectly normal! Recursion can be a head-scratcher at first, but with practice, it becomes a powerful tool. In the previous section, we saw how recursion can be used to solve problems like summing a list of numbers and generating the Fibonacci sequence. However, it's crucial to understand the potential pitfalls and trade-offs when using recursion compared to iterative approaches. 5. Common Pitfalls of Recursive Programs Recursive calls create a stack frame for each function invocation. If the base case isn't reached, these stack frames can keep growing, eventually leading to a stack overflow error. This can happen if the recursion goes too deep or if there's a bug in the base case condition. Stack Overflow: While recursion can be elegant, it often comes at a performance cost. Each recursive call involves function call overhead, and for certain problems, iterative solutions can be significantly faster. Performance: For complex problems, recursive code can become convoluted and challenging to understand. If the logic gets too nested, it might be better to refactor using iteration for improved readability. Readability: Here's an example of a potential stack overflow with recursion: function wrongFactorial(n) {
if (n === 0) {
return 1;
} else {
return n * wrongFactorial(n); // We never change the value of n
}
}

wrongFactorial(5); // This will result in a stack overflow error This function attempts to calculate the factorial of a number (3! = 3 * 2 * 1). However, it lacks a clause to change the value of n. This would cause the function to call itself infinitely, leading to a stack overflow error. 6. Recursion vs Iteration So, when should you choose recursion over iteration? Here are some ideas on that: The Fibonacci sequence is a classic example. Recursion is a good choice for problems that can be naturally broken down into smaller, self-similar subproblems. It can promote a more declarative style, focusing on "what" needs to be done rather than the nitty-gritty "how." Recursion can sometimes lead to more concise and readable code for specific problems. It typically has a smaller memory footprint and can be more efficient. However, for performance-critical tasks or problems that involve large datasets, iteration is often preferred. Ultimately, the choice between recursion and iteration depends on the specific problem you're trying to solve. Consider the trade-offs in terms of readability, performance, and potential for stack overflows. Hopefully this was a helpful introduction or refresher on recursion! Definitely practice problems on platforms like Leetcode to solidify your understanding! Cheers!

I wrote this series of posts primarily for myself, or at least someone who is trying to make something electronic to sell. If that’s you, then I hope this helps you on your journey! If you just want to see the end product then you can find it at . https://hortus.dev/products/social-battery This is a long post, so I have broken it up into chunks to make it a bit easier to digest. These are: (this article) Designing and Prototyping the Board Selling the Prototypes Online Going from Prototype to Production Introduction I wanted to experiment with JLC PCB’s assembly service - whilst I’ve designed and manufactured bare PCBs before placing and soldering components manually, I’ve got some future projects in mind that will be impractical to solder up by hand due to both the quantity and size of components. It’s kind of amazing how cheap this service is when you think about what’s involved, but it’s still expensive enough that it can be a bit daunting handing over your money, and then waiting to find out whether you’ve made some mistake that will ruin the end result. I figured I’d get started with something simple, something I could test the waters of not just PCB assembly but also e-commerce. My plan was to come up with a small item that I could realistically design and submit for manufacture in less than a day, then hopefully sell reasonably easily on a marketplace like Etsy. I was expecting the design and manufacturing side of things to be the hard part and listing the product on Etsy to be easy, but it was very much the other way around as you will see if you keep reading! The Product I had a quick scan of Etsy to look at the kinds of things people were successfully selling that I could make. I found a couple of examples of people making electronic pin badges - the perfect project! These mostly consisted of LEDs with either a random or pre-set flashing pattern on a novelty-shaped board. These looked alright to me, but I wanted to try something a bit more interactive and meaningful that I could sell for enough money to make a sensible margin on a small number of initial units. Looking at the regular pin badges being sold on Etsy, I saw a bunch of enamel ‘Social Battery’ pins with a sliding indicator. These immediately jumped out at me as something that a) I could identify with personally (people make endless jokes about my social battery…), b) would be really fun as an electronic version, and c) would be easy to design - just a few LEDs, a switch, and a microcontroller to tie it all together! Designing and Prototyping the Board Confident in my skills, I threw together a quick circuit diagram in Kicad. I decided to use an ATtiny13A - mainly because I had a few on hand from a previous project, and because I have a decent amount of experience with similar chips. If you’re not familiar with it, the ATtiny13A is a small 8-bit microprocessor with 6 IO pins and is part of the AVR family of MCUs. It’s similar to the ATmega chips that have historically been at the core of most Arduinos, except its capabilities are much more limited. The benefit is that the ATtiny range of chips are smaller and cheaper, so if you don’t need a lot of memory or peripherals, then they are great! (although possibly a bit dated now with the endless variety of ARM chips that are available). I laid out the PCB for my circuit in KiCad, then got it to spit out the gerbers and drill files (which are used to manufacture the PCB), and the bill of materials and placement files (which are used to assemble components onto PCBs). I submitted them to JLC PCB to see if they were able to process them correctly. The BoM and placement files needed a bit of tweaking from the default to get them in the right format (turns out I did this the hard way, and there’s a much easier plugin for KiCad that does everything perfectly in a single click). JLC PCB maintains a pretty large library of components that they keep in stock for assembly orders. However, in my case, the ATtiny13a was not available, so I had to order them in. This was pretty straightforward using their global sourcing service. I was able to find the supplier with the best price for the quantity I needed and then let JLC PCB order them to their warehouse on my behalf. Whilst I waited, I figured I might as well breadboard my design and start working on the code, and I’m glad I did because I immediately discovered an issue! My design used five of the IO pins available on the ATtiny13a to drive the LEDs directly (with the sixth being used to monitor the button). What I didn’t realize/remember from the last time I made this mistake (yes, It’s happened before), was that one of those IOs is also the reset pin. You can use it, but it’s not able to supply much current, and by tying it to the ground through an LED, I was keeping the chip in a permanent reset state. One way to get around this is to burn a fuse on the chip that permanently disables the reset functionality of the pin transforming it into a regular IO. The issue with this though is that you can only program the chip once (unless you own a high-voltage programmer, which I don’t), and given my propensity for learning things the hard way, that seemed potentially quite wasteful! The other option is to find a way to do more with fewer pins so that the reset pin can be left alone. This can be achieved using a technique called which allows you to address many more LEDs than the number of available pins. charlieplexing You can then scan through these LEDs, turning them on and off individually at a high rate to make it appear as if multiple are on at once through . persistence of vision In my case, I’m driving the four green LEDs from 3 pins, and the red LED with a dedicated pin. This isn’t the most efficient example of charlieplexing, as I could drive all the LEDs from the three pins, but keeping red on a dedicated pin allows for simpler code when it comes to programming. I revised my circuit diagram and PCB design, then re-exported the necessary files and sent them off to JLC PCB to manufacture and assemble an initial set of five prototypes. A little over a week later, I received my prototypes, and I was really pleased with them! There were a few things that I could see I needed to change: I hadn’t really planned how I was going to program the boards. I had just broken out the AVR programming pins and hoped for the best. This was fine for five prototypes as I could tack the programming wires on with the tiniest bit of solder, but this would get very tedious very quickly at scale. The spike for the fastener on the back was soldered onto a ground pad. This would have been fine except the thermal mass of the spike and the ground plane on the board made it difficult to make a good join. It also sticks out very close to the positive metal cage of the battery holder which meant that there was a good chance of accidental shorts occurring if people placed/attached the badge on/to conductive surfaces. The negative contact for the battery wasn’t prominent enough, so I had to add a dab of solder to it to make a good connection. Again - not the end of the world for a small number of prototypes, but a pain if I had to do this for loads. These were all simple fixes to implement. I added a proper programming header that could be used with a pogo pin jig for quick and repeatable programming. I disconnected the spike from the ground plane so that it was its own small disconnected island of copper that would heat up more easily and not cause shorts. And I expanded the negative contact for the battery so that it would have more surface area to make a solid connection. The code is pretty simple. I keep track of the mode the badge is in which is represented by an integer that gets decremented every time the button is pressed. I then loop and blink each LED on my way around as dictated by the mode. When mode 0 is reached, I reset it back to the original number and then put the ATtiny into sleep mode. Pressing the button again triggers the interrupt which wakes the chip and starts the whole process again. Overall, I was really pleased with the results, which meant it was time to see if I could sell them! You can read about my experience doing this in . the next post in this series

The Romance of Modern Mechanism by Archibald Williams is part of the HackerNoon Books Series. You can jump to any chapter in this book . CHAPTER XXV here DAIRY MACHINERY MILKING MACHINES — CREAM SEPARATORS — A MACHINE FOR DRYING MILK MILKING MACHINES The farm labourer, perched on a three-legged stool, his head leaning against the soft flank of a cow as he squirts the milk in snowy jets into the frothing pail, is, like the blacksmith's forge throwing out its fiery spark-shower, one of those sights which from childhood up exercise a mild fascination over the onlooker. Possibly he or she may be an interested person in more senses than one, if the contents of the pail are ultimately to provide a refreshing drink, for milk never looks so tempting as when it carries its natural froth. Modern methods of dairying demand the most scrupulous cleanliness in all processes. Pails, pans, and "churns" should be scoured until their shining surfaces suggest that on them the tiniest microbe could not find a footing. Buildings must be well aired, scrubbed, and treated occasionally with disinfectants. Even then danger may lurk unseen, and the milk is therefore for certain purposes sterilised by heating it to a temperature approaching boiling-point and simultaneously agitating it mechanically to prevent the formation of a scum on the surface. It is then poured into sealed bottles which bid defiance to exterior noxious germs. The human hand, even if washed frequently, is a difficult thing to keep scientifically clean. The milkman has to put his hand now on the cow's side, now on his stool; in short, he is constantly touching surfaces which cannot be guaranteed germless. He may, therefore, infect the teats, which in turn infect the milk. So that, for health's sake as well as to minimise the labour and expense of milking, various devices have been tried for mechanically extracting the fluid from the udder. Many of these have died quick deaths, on account of their practical imperfections. But one, at least, may be pronounced a success—the Lawrence-Kennedy cow-milker, which is worked by electricity, and supplies another proof of the adaptability of the "mysterious fluid" to the service of man. On the Isle de la Loge in the Seine is a dairy farm which is most up-to-date in its employment of labour-saving appliances, including that just mentioned. Here a turbine generates power to work vacuum pumps of large capacity. The pumps are connected to tubes terminating in cone-shaped rubber caps that can be easily slipped on to the teat; four caps branching out from a single suction chamber. As soon as they have been adjusted, the milkman—now shorn of a great part of his rights to that title—turns on the vacuum cock, and the pulsator, a device to imitate the periodic action of hand milking, commences to work. The number of pulsations per minute can be regulated to a nicety by adjusting screws. On its way to the pail the milk passes through a glass tube, so that the operator may see when the milking is completed. This method eliminates the danger of hand contamination. It also protects the milk entirely from the air, and it has been stated that, when thus extracted, milk keeps sweet for a much longer time than under the old system. The cows apparently do not object to machinery replacing man, not even the Jersey breed, which are the most fidgety of all the tribe. Under the heading of economy the user scores heavily, for a single attendant can adjust and watch a number of mechanical milkers, whereas "one man, one cow" must be the rule where the hand is used. From the point of romance, the world may lose; the vacuum pump cannot vie with the pretty milkmaid of the songs. Practical people will, however, rest content with pure milk the beauty, in preference to milk the microbe and the milkmaid, who—especially when she is a man—is not always so very beautiful after all. minus plus CREAM SEPARATORS In the matter of separating the fatty from the watery elements of milk machinery also plays a part. The custom of allowing the cream to "rise" in open pans suffices for small dairies where speed and thoroughness of separation are not of primary importance. But when cream is required in wholesale quantities for the markets of large towns, or for conversion into butter, much greater expedition is needed. The mechanical cream separator takes advantage of the laws of centrifugal force. Milk is poured into a bowl rotating at high speed on a vertical axis. The heavier—watery—portions climb up the sides of the bowl in their endeavour to get as far away as possible from the centre of motion; while the lighter particles of cream, not having so much momentum, are compelled to remain at the bottom. By a simple mechanical arrangement, the—very—skim milk is forced out of one tube, and the cream out of another. An efficient separator removes up to 99 per cent. of the butter fat. Small sizes, worked by hand, treat from 10 to 100 gallons of milk per hour; while the large machines, extensively used in "creameries," and turned by horse, steam, electric, or other power, have a capacity of 450 gallons per hour. The saving effected by mechanical methods of separation is so great that dairy-farmers can now make a good profit on butter which formerly scarcely covered out-of-pocket expenses incurred in its manufacture. A MACHINE FOR DRYING MILK Milk contains 87 per cent. of water and about 12 per cent. of nutritive matter. Milk which has had the water evaporated from it becomes a highly concentrated food, very valuable for many purposes which could not be served by the natural fluid. Until lately the process of separating the solid and liquid constituents was too costly to render the manufacture of "dried milk" a profitable industry. But now there is on the market a drying apparatus, manufactured by Messrs. James Milnes and Son, of Edinburgh, which almost instantaneously drives off the water. The machine used for this—the Just-Hatmaker—process is simple. It consists of two large metal drums, 28 inches in diameter and 5 feet long, mounted horizontally in a framework with a space of about one-eighth of an inch between them. High-pressure steam, admitted to the drums through axial pipes, raises their surfaces to a temperature of 220° Fahr. The milk is allowed to flow in thin streams over the revolving drums, the heat of which quickly evaporates the water. A coating of solid matter gradually forms, and this is scraped off by a knife and falls into a receptacle. The milk is not boiled nor chemically altered in any way, though completely sterilised by the heat. This machine promises to revolutionise the milk trade, as farmers will now be able to convert the very perishable product of their dairies into an easily handled and imperishable powder of great use for cooking and the manufacture of sweetmeats. Explorers and soldiers can have their milk supply reduced to tabloid form, and a pound tin of the lozenges will temper their tea or coffee over many a camp fire far removed from the domestic cow.
