If you are looking for something advanced, you should check books written by C. J. Date. For example, his "An Introduction to Database Systems" considered as one of the best book o…

Another interesting project of next-gen file system is Red Hat Stratis: https://stratis-storage.github.io/ After dropping btrfs support some time ago they started developing their …

Actually, it is quite opposite. ZFS is a copy-on-write filesystem - if you do write in the middle of your file the datablock gets moved to a new place on your disk. For typical dat…

On my previous job we had to manage thousands of customer domains, including annual renewal. This was very tedious task, so I wrote a Perl script, scraping WHOIS and DNS data for a…

Thank you, I did not know that. It is sometimes very surprising to see such identical idioms, while English and Russian languages are so different.

Interestingly, Wikipedia translates "Nu, pogodi" as "Well, you just wait". Actually, this phrase is a threat and should be translated something like "I will get you".

To solve the problem with non-US character-encoding. Web browsers of 90s were notoriously bad with client-side encoding. The only way to show content properly for all available cli…

In Russia we served HTTP traffic on non-standard ports, such as 8100, 8101, 8102 in addition to default 80. It was very common in 90s. Can anyone guess, why?

I was surprised to find Web of Trust addon ( https://addons.mozilla.org/en-US/firefox/addon/wot-safe-brow... ) in top 10. From my past experience https://mywot.com is nothing more …

Best comment. :-)

You should not judge about all Russians by those tourists. Unfortunately, during last 20 years in Russia, being such scoundrel and scumbag, you have pretty high chance to earn good…

Actually, Russians smile quite a lot. They are not smiling to strangers - the article explains why. But this does not mean they are not smiling at all. Once you become acquainted t…

I hope, having read the article, you can now understand their behavior.

Moscow is not a country. But I agree with you - people living in Moscow have very few reasons to smile to strangers.

I immediately remembered about this story too. This is pretty hilarious: "Containing a Harry Potter book, the letter was sent to a Russian student by her French friend, who manuall…

It's a fake. http://ria.ru/science/20120917/752346830.html Google translate: http://tinyurl.com/9kqjr3t TLDR: There are so called "technical diamonds", they are not good enough for…

You are probably talking about apt-xapian-index. It rebuilds its indexes once a week, consuming all system resources. I had an old notebook, which became unusable every weekend. I …

to henrikschroder: I expected that this reaction was caused by mentioning a book. It is my deepest belief that questions like memory management can not be answered with brief comme…

If you want to be more enterprisey, you can pipe it to SNMP counter and then draw a graph with your Network Monitoring System. It is much more convenient if you have more that few …

Thank you. I'm on my way to become exceptional DBA. Oracle is only 2 years younger than me, but unfortunately it has been developing much faster than I am. It literally takes years…

Why downvoting? It may be not the best explanation, but IMO the closest to the way a "developer" should understand it. On Linux a virtual memory is committed with mmap call. Check …

Well, if you don't understand it, you must read some basic book about modern computer architecture. Short answer: It is possible to reserve memory address space without assigning a…

As a longtime Linux user/admin and beginning Oracle DBA I now know that all memory should be occupied by Oracle, not by OS. :-) Serious mode on: I'm sure it's a big problem to be n…
