Good dev knows

⚡️ Channel needs your energy Telegram just dropped stories for channel functionality. It is not enabled by default, subscribers of the channel need to boost the channel to enable stories posting. For our channel we need just 12 boosts. And another interesting piece of statistics — we have 346 premium members here, already. Btw, being in Germany, I can not buy premium neither can I be gifted one. But there is a positive side as well — no Telegram ads. Each time I live Germany they start to appear. 🚢Let's boost and see what happens. For example, I would have shown you a giant ship a day before yesterday if I had that option. https://t.me/gooddevknows?boost

🧪 ChatGTP hallucinations Today I got tricked by ChatGTP. I asked it to help me write a custom AWS policy, and it quite confidently told me that I shall use

{"s3:RequestTag/validationProvider": "TEST"}

and everything will be great. So I did it this way, AWS accepted my code, but nothing was great, and the thing I wanted to work — did not. After some time of googling and checking the AWS IAM UI I found out that there is no RequestTag for S3, but there is RequestObjectTag. I made that change, and it started to work as I wanted it to 🚀 Still, I can say ChatGPT saved me some time, but we shall not forget that we cannot trust it blindly. Honestly speaking, it wasn't a complete hallucination because there is such a thing as RequestTag at AWS; it just has a different context, not the S3 one. Happy ChatGTP to everyone!

❄️ Unique ids We need ids to store the records and later refer to them. Numeric ids are good, but usually you do not want to expose them to the end customer because they can be enumerated. There are alternatives. Let's explore them. * uuid. This is a standard, right? It's a default that everyone uses to generate a unique id. You can use this id and assume that no other machine or person in this universe will generate the same one. Example: 858e93a4-ff8d-11ed-be56-0242ac120002. * nanoid. Small js (and not only) library, which generates short ids. Short ids and a small size are the benefits of this library over the "default" uuid/v4 that it generates shorter (you can even choose the length) ids and the size of the library is smaller. Example: zWSK7f4at3iI7TdMP-mYz. * ulid. This one was new for me. It generates unique ids that are sortable in time. So when you have two of them, you can learn which was generated earlier. Basically, the timestamp is encoded there. Example: 01H1RF7HDAH1MY7E05S6MFC8QS. ⬛️ Do you know any other interesting approaches? Please, share.

👋 Good day, Just published a long read called "How to be a great feature lead", where I summed up my experience of being such for many many times. There is no clear definition in the community what does it mean to be a "feature lead", but we all do that at some point. Being a feature lead is a safe stepping stone in your career development path, but not only, you will play such role almost on any grade. This is why it's important to know how to play it right — making it beneficial both for you and the business. This article, unlike many other ones, tells you about the role from the "soft skills" perspective. They are not related to the project or to the technology which you are using, these skills and attitude will help you throughout your whole tech life. The article is really long, but it's another benefit — it covers the process end-to-end. After you read it, you will be able to use these tools right away, no matter where are you now from the feature lead process perspective. Hope to get your feedback either here or on Medium. This article is also available on dev.to.

📚 Modern Software Engineering I promised to deliver you an exclusive content in March and here you are. Review of the book "Modern Software Engineering" — everything what you need to know to develop confidently. I decided to publish a video instead of the live session, so more people can watch it with their own pace. Please, share what do you think of it in the comments.

Good day, everyone, Thanks for the active participation in the fundraising. Your donations mean a lot to me 🤗 But not only to me, we are doing the right thing. Here I report about the results:

Money were already transferred to the destination organisation. Have a good day ☀️

Good day, Here are the first stats about the fundraising. Together we've collected. 632.16€ and 1860₴ + 200€ from me. Average donation in EUR is 50€. Biggest donation in UAH is 1000₴. Not bad, but we can do even better. Every cent counts, please, spam me with microdonations. Let's talk a little about the cards themselves. On average, the whole process of the vehicle delivery to Ukraine costs 6000$. These costs include car purchase, fuel, export declarations, train tickets for the people who drive the cars, etc. As you see, what we have is already around 1/5 of the car. But we can do more. Please, continue your donations 🤝. Here are the requisites: IBAN: DE69100110012620227756, Pavlo Poliakov; BIC: NTSBDEB1XXX PayPal: https://www.paypal.com/paypalme/PavloPoliakov or [email protected] Mono: https://send.monobank.ua/jar/63kXNYa6Nv Below I will attach a video report for the last year, where you can see all variety of cars, which were delivered. That's really impressive. Thank you and Glory to Ukraine! 💙💛
