In the past, I helped organization growing 2x revenue in just 6 months with pragmatic yet effective thinking and collaboration across teams. I also helped organization to scale properly - surviving BFCM is one of them.

I also love good documentation. To quote: "People who say documentation shouldn't be necessary have never experienced good documentation."

I am pretty much agnostic in terms of technology, because there is no silver bullet. Speaking of that, I shipped applications with Ruby, Java, C#, and Go.

Feel free to ping me via my email to discuss how we can work together.

Well,

> To protect the data that is not covered by end-to-end encryption, Telegram uses a distributed infrastructure. Cloud chat data is stored in multiple data centers around the globe that are controlled by different legal entities spread across different jurisdictions. The relevant decryption keys are split into parts and are never kept in the same place as the data they protect. As a result, several court orders from different jurisdictions are required to force us to give up any data.

If we register Telegram, Telegram has our master key. I am not sure they are really that secure. Yes, it makes politically hard to disclose any data, but it does not mean impossible.

I design platform-agnostic software, construct software, help people write software better and more effective. It is very thrilling for me to build high performance, maintainable, and scalable software. I've worked on high traffic systems with $1B+ monthly revenue and maintaining it at very high uptime.

Time wise, my experiences include 5+ years software development and leading a team in various platform. My experience fields include Fleet Management software, geography mapping, remote device tracking, credit card payment, SEA payment, commerce (promotion, discount, voucher).

I have experience with various programming languages, such as C, Java, and Ruby, but i code mainly in Ruby and Java. In fact, i am a fast learner and i can grasp new concept in short time. By platform-agnostic, it also mean I can learn current codebase rather quick.

In my spare time, i love to leverage developer communities by sharing some insights. I was speaking in latest Ruby Conference in Jakarta about one of important parts about software stability: understanding and preventing race condition. The conf was here http://ruby.id/conf

Relocating is fine for me. I am also familiar with remote working. I need visa sponsor to work.

I find starting something is easier than closing / shutting it down. We know several metrics to start something. Demand, high chance of success in the future, niche market, etc. But how do you think about shutting down something? I mean, how to distinguish "failure", "must struggle a little bit more", and "buying more time"?

To close something seems like not trivial.

Exactly. Once we can understand P vs. NP completely, all cypto algorithm today will be obsolete since crypto algorithm today ONLY rely on that "hard" problem.

New comment by fidz in "Truly Seamless Reloads with HAProxy"

fidz — Fri, 05 May 2017 00:37:18 +0000

I wonder, how does nginx and haproxy handle long/persistent connection session? The connection itself can't be terminated since there is actual client, established connection with a backend beneath. Will the reload be failed? (Something like, "connection termination timeout; can't reload; try later"). For web workers probably we won't see this; for most of the time, the connection is terminated after request done.

Apologize for my brevity, but i really wonder: this has been previously posted dozen times, but why it is popular now? I wonder if the time of link posting (morning/noon/evening) can actually determine the popularity of the post.
