Search/ads and ride/delivery services. As you may know Yandex has very advanced SDC system which was used(SDC robots) by Grubhub in Arizona University. They have delivery services in London/Paris and taxi services in Insrael

> how much does language matter in job satisfaction? I think it depends. I hate JavaScript and Python. My coworkers don't care about language. They are working on the product, the goal is a fully functional service with a huge DAU.

There is one more reason. When you write something that works in a loop, e.g. web server, exceptions are a huge potential issue. I was working on a C++ project with a very complex state machine. One day our service started using all 128 CPU

I'm working in a company with 20+ years of the legacy code base. We have a custom search engine fully optimized for our purposes. Decades were spent writing this code. It supports all the newest Linux kernel technologies. The codebase

Because of the misinterpretation of Baseline Requirements for stateOrProvinceName field lot of CAs issued certificates with ST = Italy/France/etc. Now Firefox is forcing to reissue thousands of certificates in 5 days.

I found this https://www.reddit.com/r/Starlink/comments/i9w09n/list_of_co... It's pretty good for far remote regions like Alaska. Fibre channel will be much more costly with comparable RTT.

I think the main problem is spare parts. A long time ago I was working in the data centre. I don't remember any day when there was no problems with hardware.

The signal goes through the ionosphere to the satellite than to another satellite which has a link to the Earth. Starlink uses LEO, so there is 2400 km link(1200 km from/to the ground). 1 ms is time for the signal to travel for 300 km

Yes and no. If you are living near base station in a big city it will work. But in the countryside where no good connection from ISP equipment to the base station the bottleneck will be this link. Furthermore, 5G uses a higher frequency tha

This reminds me of how someone tried to reduce Linux kernel size with removing spaces from sources :)

There is no need to send extra data to measure RTT. On the TCP handshake SYN/ACK you already know RTT. Linux kernel provides this info in tcp_info data structure.

I think it will be better to fully disable early data for people without full control of DC's network equipment. I don't know why Cloudflare made a decision about using headers and Too Early response. They have full control of the

From Power9 cluster with array of GPUs? For work loads like http servers/php code/MySQL/etc intel CPU will be much faster. We have CPU samples from all vendors, unfortunately Intel right now is the best platform.

Power clusters are used for ML because they have integrated NVLink and as I remember OpenCApi for FPGA. It’s not general purpose platform.

We use fingerprinting to detect unusual activity from clients. I think for platform detection it will be better to check JavaScript + User-agent + fingerprint.

No, it's not full implementation. The main difference between this and Zalewski implementation is using direct mapping data between kernel space and userspace. Zalewski implementation uses pcap for capturing packets. If you have huge w

Hope someone will find this code useful in his project. This is a proof-of-concept, full code can't be published.

Envoy is not the web server, it's load balancer. If you want to serve static files It will be better to use any other software. Furthermore, it is a very complex problem for HTTPS servers, because the Linux kernel doesn’t have full-fea

It may help if you use a single data source. But we are using more than 2000 data sources and all they distributed/replicated in different data centres across different countries.
