Programming Tips 💡

In recent years, there is a lot of interest in the techlead role in software development. There are many discussions about what the role is and what it is not. Some articles explain it as CTO, some see it as a lead software developer, and some consider as a fully separate role in the team. While there is no clear agreement on techlead definition in the industry, one thing is certain: being a techlead requires strong technical skills and deep expertise with a good mix of leadership and other soft skills. The only way to effectively grow in this area is continuous learning in system design, architecture, engineering practices and self-imrpovement in communication and presentation skills, leadership, conflict resolution. If you're a techlead or thinking about becoming one, you should definitely check out the @techleadbits channel. They break down useful articles, books, videos, and share personal experience from a techlead's life. It's full of insights and tips that can really help you grow in this role.

Designing APIs for humans: Object IDs 🧑🏻‍💻 Ever wondered why Stripe uses foloowing format to generate unique IDs? Let’s dive in and break down how and why Stripe IDs are structured the way they are: pi_3LKQhvGUcADgqoEM3bh6pslE └┘└────────────┘ └─ Prefix └─ Randomly generated characters You might have noticed that all Stripe Objects have a prefix at the beginning of the ID. The reason for this is quite simple: adding a prefix makes the ID human readable. ✔️ Without knowing anything else about the ID we can immediately confirm that we’re talking about a PaymentIntent object here, thanks to the pi_ prefix. This helps Stripe employees internally just as much as it helps developers integrating with Stripe.

$pi = $stripe->paymentIntents->retrieve(
  $id,
  [],
  ['stripe_account' => 'cus_1KrJdMGUcADgqoEM']
);

The above snippet is trying to retrieve a PaymentIntent from a connected account, however without even looking at the code you can immediately spot the error: a Customer ID (cus_) is being used instead of an Account ID (acct_). 🔖 Without prefixes this would be much harder to debug; if Stripe used UUIDs instead then we’d have to look up the ID to find out what kind of object it is and if it’s even valid. 👨‍💻 [ Read More ] : https://dev.to/stripe/designing-apis-for-humans-object-ids-3o5a 〰️〰️〰️〰️〰️〰️ #UUID #Stripe @ProgrammingTip

OpenAI .NET 👾 The OpenAI .NET library provides convenient access to the OpenAI REST API from .NET applications. ✔️ The full API of this library can be found in the api.md file, and there are many code examples to help. For instance, the following snippet illustrates the basic use of the chat completions API:

ChatClient client = new(model: "gpt-4o", "OPENAI_API_KEY");

ChatCompletion completion = client.CompleteChat("Say 'this is a test.'");

Console.WriteLine($"[ASSISTANT]: {completion}");

The library is organized into several namespaces corresponding to OpenAI feature areas. Each namespace contains a corresponding client class: • AssistantClient • AudioClient • BatchClient • ChatClient • EmbeddingClient • FineTuningClient • FileClient • ImageClient • ModelClient • ModerationClient • VectorStoreClient [ GitHub ] : https://github.com/openai/openai-dotnet 〰️〰️〰️〰️〰️〰️ #AI #OpenAI #DotNet #CSharp @ProgrammingTip

Bloom Filters 🆒 Imagine ensuring web safety by identifying malicious links without storing massive data. Traditional methods involve keeping a huge list of bad links, consuming substantial storage and bandwidth. Enter Bloom Filters - a genius method allowing us to significantly reduce storage needs (up to 82% smaller) with a minimal error rate. 👾 For instance, instead of a 20MB list for 1,000,000 links, a Bloom Filter achieves this with just 3.59MB, accepting a tiny error chance (0.0001%). Even more impressive, with a 0.1% error tolerance, the size shrinks to 1.8MB. This technique was even utilized by Google Chrome until 2012. ✔️ Bloom Filters offer a balance between efficiency and accuracy. For critical checks, it pairs with a database API for zero false positives. A practical, space-saving solution for modern web browsers! ⚡️ [ Article ] : https://samwho.dev/bloom-filters 〰️〰️〰️〰️〰️〰️ #Algorithm #BloomFilters @ProgrammingTip
