This should be taken to heart by every technologist, or to be precise, pure technologist. Being pure tech today is about as useful as being a typist during the type-writer era i.e. specialized skill that is in demand, but by itself (with few exceptions) is only secondary to the domain it is applied in.

Most so-called "tech" companies are not really tech, but more in (tele)communications, media, advertising, surveillance data businesses.

It is easy to see the time when everyone can do technology. This surely happened to typing, it would be ludicrous trying to get a job as a typist today. Same can happen to the pure tech: a) due to technology itself e.g. web-site builders, etc. b) education,- everybody learns to type today, its a bit of a stretch, but maybe everybody can learn to program.

Aside from job security argument, the value creation is happening in the domain where business is focused, not necessarily knowledge of technology. Technologists who understand the domain can deliver much more value, and command higher premiums.

Let's be clear, there was no private property at the time in the Soviet Union. Moreover, what was called "personal" property, was very limited. For instance, the ownership of pretty much any gun was prohibited (maybe with the exception of hunting rifles). Therefore, the word "bought" is highly misleading. Even if she could buy a tank, let's do the numbers. Based on the following page https://en.wikipedia.org/wiki/T-34 the tank cost would be at least 135,000 1943 rubbles. Making a comparison to M4 Sherman, which was about $45,000 1941 dollars, we will come to about 3 rubles to 1 dollar hypothetical exchange rate. Therefore the donation to mother-Russia of 50,000 1943-rubles is an equivalent of about $17,000 1945-dollars, or about $214,000 in 2017-dollars.

Now we finally can understand what piece of KGB-knitted propaganda this article is. I lived during the soviet times, and the median salary was barely covering food and clothing. Even today, the median income in Russia is less than $1000 per month. Did she work all her adult life without spending anything? Please keep in mind that productivity today is much higher.

Thank you for your answers. To summarize, we have 1) Hobbes 2) hacked LMDB 3) C++ memory-mapped store of arrays.

Given that options #2 and #3 require some (non-trivial) work, they are not really options.

We left with #1,-- hobbes, which was uploaded to GitHub about 5 months ago and has a whopping team of 2 contributors, both employed by Morgan Stanley.

This is more than nothing, but not much.

I do not have experience with KDB, and looking at the language syntax, not a fan. Integration with Python (depending on implementation) may push KDB towards larger acceptance.

So far I was mostly relying on a variation of the option #3.

What are the open source offerings that you referring to? The ones that provide 1) no-copy analytics 2) i/o stack bypass i.e. memory-map.
