Ivan talks about computers
เข้าร่วมเมื่อ 16 ต.ค. 2016
Hi! I'm Ivan, I try to make videos that explain things that are interesting to me, including the following: Web Apps, Containers and Orchestration, Microservices, Programming Languages and others.
Save time debugging with bash's `history`
To get back into videos, I decided to make one about something small, but which has saved me hours of debugging time!
I hope they help you as well!

Tests !== quality
มุมมอง 8605 ปีที่แล้ว
👋! In a lot of cases we confuse building quality into the software with writing automated tests. In this video I'd like to explain what tests are and how can they be used to improve the quality of your software. I hope you enjoy it!
Serialization formats: JSON and Protobuf
มุมมอง 109K7 ปีที่แล้ว
When programs want to send data between each other, they have to make it available in a commonly understood format. Choosing a format for exchanging data is becoming increasingly important the more data you exchange and the more you rely on its consistency. In this video we will take a look at two popular formats for serializing data - JSON and Protobuf.
B-Tree Indexes

In this video, I'd like to take a look at B-tree indexes and show how knowing them can help design better database tables and queries.
Efficient analytics with Redis Bitmaps
มุมมอง 5K7 ปีที่แล้ว
A short video on how you can use the Bitmap commands in Redis to get some analytics data. Music by the evolutionary Darwin Tunes
Google AMP (Accelerated Mobile Pages)
มุมมอง 12K7 ปีที่แล้ว
In this short video, we'll look at how the internet works and how the Accelerated Mobile Pages project makes it faster. AMP (or Accelerated Mobile Pages) is an open source project that creates a new standard for how web pages work. The pages, built using a subset of HTML, with little CSS and almost no Javascript are well suited for non-interactive content, such as news, ecommerce, blogs, etc. W...
What is Docker?
มุมมอง 11K8 ปีที่แล้ว
Hi! In this first video I'd like to explain what is Docker. First we present the context in which Docker has appeared and later we show how to write a Dockerfile that would create an image. We'll also run a small Node app inside the container booted from our new image. If you have topics to suggest, feel free to comment on this video!

if the bitmaps can store 2^32 bytes and we use them e.g. to store only when a user was logged in, then: in case user logged one time on any month, and only one time in this year -> is the bitmap created with size 2^32 and stores only 1 value of some small size (do we know what size?) it can store 4 billion combinations of an item or separate items? the cell on your video refers to id or month or what?
yass this is the sort of succinct explanations i was looking for. thanks. subbed 👍🏻
Hey Ivan, why did you stop making these videos? Your videos are really interesting
Great video and explanation!
I don't understand why at 3:56 you say datetimes cannot be indexed. I'm pretty sure that isn't accurate.
Great video! Best explanation I've seen! Thank you!
Thanks for the video. It would have been great if you presented the protobuf binary size (51B) and compared it with the JSON (since you explained that the JSON example was 51B)
1:00 this graph has no labels and shows exponential growth not linear
Well introduced
Very good explanation. Good job, Ivan!
Json string doesn't represent numbers as ASCII character?
Need help on converting proto Api file into swagger json?
The music is very bad I wished if the video without music
A 64 bit integer would be 8 bytes.
Thank you for the explanation, but I guess I am wondering, what should we be indexing?
whaat software do you use for animation in the video ?
Дизлайк. Нет перевода на русский
Sunch an amazing video! Thank you!
Very clear explanations! Thank you!!
Wow this was excellent mate! Thanks for doing this 👍
Im shocked on the information and delivery. Very good. Thank you.
Awesome explanation! 🤩🔥
Great vid!
please keep the good contents going, love your video!
Video iz amazing I think b+ trees also should been mentioned
Hey Ivan! Any plans to make more videos?
очень круто рассказал все за 5 минут, надеюсь у тебя появится время сделать такое же видео про grpc, потому что они все по 30 минут на ютубе не очень понятны
video nhu cc
If you are using JSON a lot, then DeltaJSON is really useful for compare, merge and patch.
Thanks for this - you have the knack for top quality content, would love to see more!
i cant focus to that music....
Why did Ivan stopped talking about computers? It was the shortest and to the point explanation. I appreciate also showing examples of when to use and alternatives at the end.
great video
Keep it up, Ivan! Spot on content!
Great video and nice explanation. Please which software and material s do you use for the video. Please
Hi Ivan, I think you should buy a better mic or repair the echo, but I like this video so much! Thank you.
Ты классный, спасибо)
I waste my 4minute and 32 seconds thanks for the nice video!
awesome explanation
No word for this knowledge sharing. So simple and to the point in a small video. Thanks
Access to the disk is expensive? Have you learned it from HDD times, rather than SSD? 🙃
Hehe. Good times though!
Good video, but damn that echo!
I saw your content... and it's great, I think you need to continue. I think I will just subscribe and give a like, that's all I can do.
Thank you! Working on it!
i dont get it.......
I can not compute Json massive 51 4 byte integer 19 byte character Where is my 28 byte?? Can you explain?

JSON vs BSON смотри сейчас! th-cam.com/video/w9UuJprl-Sw/w-d-xo.html
Thanks for the video this helps me a lot for have a better differentiation between JSON and Protobuf.
why not do more videos consistently? you explain really well, and i like to learn more from you
Waw, thank you for this information of b-tree. I'm from Indonesia and i like your video!
