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 on database theory.
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 own next-gen file system based on LVM…
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 database load your db files get more and…
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 all domains listed on our DNS servers.…

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 clients was server-side recoding and…
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 than a scam. Their ratings are not…
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 money. Even in Russia nobody likes…
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 to the person, the smile becoming the…
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 manually transcribed the address that he had…

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 did not want to buy a new machine, so 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 comment. You must read at least a basic book…
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 servers.
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 just to become familiar with all these…
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 this for details:…
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 actual physical memory. As your program…
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 narrow expert. They can be brilliant…
Me too. I highly suspect Coca Cola was specifically designed in a way that it can not quench one's thirst. Once you open a bottle, you can not stop drinking it until it is finished. That's why I completely stopped…
