News on China's scientific and technological development.

Lol OS is one of China's would be strengths if tested. Without even requiring to, china has long developed and been using a dedicated military, strategic and government department use OS - Kylin.

Huawei's Hongmeng OS and Harmony 2 for overseas is functionally as good as any established ones and even better, able to be more integrated with Chinese infrastructure within China.

If pushed to only use and develop even more OS due to being cut off from using American ones, this is a field china would absolutely excel in and honestly would be a good thing to diversify away from civilians mostly using iOS and windows and Google's.

Can Russia cover any of these temporarily or does this report only take into account those provided by US aligned countries?

Russia makes aviation design software, aviation-grade steel, high strength stainless steel, epoxy, and aircraft engine nacelles out of that list.

There is nothing particularly hard about making engine nacelles. The main issue is having the design tools and wind tunnel practice to test the designs. The manufacture proper is not that hard. In the case of CR929 the Russians are also doing wind tunnel testing so I doubt this will be an issue.

Russia has programs to produce their own F-class gas turbines in a mature state but these are way too small for a country like China.
China has gargantuan power generation needs so they should go straight for H-class gas turbines and the like.
In the case of Russia they want to use gas power for all their small and mid size cities, with some in larger cities as backup for nuclear power. Russia also wants gas power plants to have combined heat and power so they can use district heating. This is something that in the case of China would only apply to the North of the country like Liaoning but not, say, Shanghai where current a large part of gas use is. So Russia and China's needs in terms of gas turbine design for power generation have little overlap. Overlap between design needs of gas turbines for power generation of both countries exists but is limited.

The situation in OSes and DBMS seems kind of overblown to me since there is open source in both categories that is as good or better than the commercial software.

Yeah there are actually some really good looking linux distributions from China like Deepin. In my career outside of Microsoft c#/asp based gig, most databases have been either mysql or postgresql both opensource and those are the so called "Classic" relational databases. Then you have nosql kinds the so called "webscale" ones like mongoDB.

The bigger ones are open source, but the latest movement is centralising compute and storage on cloud providers from what i have seen from Alibaba cloud and Huawei cloud products China has everything you need to create a software ecosystem. Not sure how the state of general software is in China(SME companies) but here in the Netherlands going to the Microsoft Azure or Amazon AWS cloud is the way to go.

Evening the Americans are leaving Oracle and now using MySQL and Postgresql.

Those things are really slow. Oracle is not fast enough also.

For large volume, low latency stuff, I have to use column based DB like KDB and vertica these days.

you know, this is the basic problem of these so called experts, they always been outdated. largely unaware of China's recent development and progress. China also conquered heavy duty gas turbines. E and F fully indigenous. H is in final phase of development.

Not really their fault. If you don't follow the development on a monthly basis then your information is automatically obsolete.

I read the article. It seems the problem is the lack of investment by corporations which is mainly caused by risk avoidance.
This is unacceptable for China. The Chinese economy is big enough and China is in a strategic rivalry. Both are truer today than they were in 2018. I hope the gov is encouraging and, if needed, forcing corporations (especially state owned corporations) to use domestic equipment even if it means lower profits. China having strategic dependencies is too high of a cost for having a few percent higher revenues.

Kdb and vertica are time series database and not rdbms. For rdbms my prediction is that postgresql will probably become the defacto standard. And it is FOSS.

i have read this article. this was before trade war/tech war. we are in 2022 and a lot things have changed since then.

China has overcome so many problems and bottlenecks.

The China of the pre-trade war and the China after the trade war started are 2 different countries
