Interestingly, operators are required to store phone conversations, but nowhere does it say in what quality? What’s to stop them from compressing them so much that they take up very little space and are barely, but discernibly, intelligible? After all, they do make mandatory inscriptions on advertisements in tiny letters, and somehow everyone copes with that.

Or consider internet traffic. Some of it cannot be decrypted at all. If something can’t be decrypted, why not compress it to (hypothetically) three bytes? Either way, a data retrieval request will only show binary garbage.

New post on my blog. I managed to create a separate cluster from Hybris for promotion calculation.

In the latest version of Hybris, they introduced a new promotions engine, built on rules. There is a convenient interface where you can construct complex rules with intricate conditions and publish them on the site immediately.

But thereโ€™s a catch – the engine is only integrated into the shopping cart. And a few minor places and the call center software. I set myself the task of calculating promotions for each item on the search page and category page.

Simply calling the functionality twenty times wonโ€™t work. Firstly, there are some issues with interfaces, but even if those are resolved, the calculation would be too slow. To make the page loading time somewhat acceptable, it would be necessary to increase the number of servers, which with Hybris isn’t the best option, as in most cases licenses are sold per CPU.

Interestingly, the USA has not produced a single artistic biographical film about George Washington. Or maybe I’m just bad at searching.

There’s a good film about Gandhi. There’s an excellent one about the “Iron Lady” in England. At least five films have been made about Hitler, including Tarantino’s Inglourious Basterds. There are a number of films about Stalin and Lenin. But nobody has made one about Washington. It’s understandable that they would have to fully depict slavery and other unpleasant things, but still, it’s the 21st century! ๐Ÿ™‚

I’m planning to go to Mount Vernon, wanted some educational entertainment, but there are only documentaries and one obscure TV series about Washington that nobody knows, consisting of three episodes.

Liza and I just watched the first episode of Brain Games. It’s this new type of documentary about how our brain works: illusions, perception features. Very interesting and highly recommended. For those who understand a bit of English, it’s probably better to watch in the original language. It’s very simple, in my opinion. Available on Netflix with subtitles.

In the States, it’s common practice in the service industry to ask for the full credit card number and expiration date over the phone. A hotel clerk could easily walk away with a stack of real card numbers, but presumably, if there’s fraud, there are ways to trace the clerk and the security system is balanced. But still, I can’t get used to it. I was taught as a child never to give my card number to anyone.
