Descending to the garage, I agonizingly choose which wheels will carry me to work today. #allflavors

Lord, we now have six bicycles. I am a bike magnate! Bought two more today. Selling one now, if anyone is interested;)

Interesting information.

June-August 1894. Oliver Lodge demonstrated the transmission of a radio signal (using Morse code) over 40 meters. However, the device was not reliable enough. Lodge did not further develop his experiments. To some extent, he was the first, not Popov and Marconi. http://collection.sciencemuseum.org.uk/objects/co35266/hertzian-oscillator-1890-1894-scientific-equipment

April 1895 (8 months later) A. Popov demonstrated a test protocol of a device receiving radio waves. http://www.museum.ru/C6571

March 1896 (a year later) A. Popov demonstrated the world’s first radio transmission and reception of meaningful text from one building to another over a distance of about 250 m.

September 1896. Marconi conducted his first public demonstration of his receiver and transmitter on Salisbury Plain, achieving transmission of radiograms over a distance of 3 km.

A year later, Tesla was already demonstrating transmission over 30 km.

This relates to the questions of “who was first” and “how science works”

And I was a part of this 😉 happy holiday)

“… The celebration of Radio Day at the Ryazan State Radio Engineering University annually gathers thousands of students and graduates at the walls of the educational institution. The holiday begins with a procession on the night of May 7th around the monument to A.S. Popov, near the university building. Celebrants greet each other with the words: ‘Popov has risen!’. In response, it is customary to reply: ‘Truly, Popov!’. It is a tradition to give friends painted radio tubes and attach radio parts to clothing. Since 2012, the university administration has been taking measures to prevent the night-time part of the event’s celebration…”

So, in the 41st year of your life, you learn that the correct emphasis in my name should be placed on the second syllable, not the first, as my parents always called me)

Does anyone know how to set up a VPN on a Mac for torrents in such a way that the torrent client doesn’t even attempt to access the network except through the VPN?

If you just set up a VPN and connect, you might forget to turn it on, or it might disconnect due to connection issues, and if the torrent client is active at that time, there would be unprotected traffic.

I’d even settle for “no internet at all without a VPN.” To do this, I need to somehow limit any external connections other than through the VPN gateway (after which, I assume, everything would go through the gateway). I suppose this can be done via iptables, but I lack the experience. Does anyone know?

P.S. Found something https://www.ibvpn.com/billing/knowledgebase/152/-IP-Bind-in-uTorrent—Download-Torrents-only-via-VPN-Windows-OpenVPN.html

An update of SAP hybris blog! The purpose of the new post on the blog is to shed a light on the internal data structures used by SAP Hybris Commerce. I explain system tables and attributes, their purpose and meaning.

You know that SAP Hybris Commerce has a powerful type system built on top of the database layer. It means that you can’t (you are not recommended to) write to the database directly. Direct read is also not recommended. So basically the information about the specific attributes and table names is not used by developers directly.

However, understanding of the internal structure is very useful in troubleshooting and low-level data analysis. For example, direct access to the database may show that your system has a lot of unused items, and it affects the performance. Analyzing the data is also extremely helpful with data integrity issues.

Looking at the underlying data model you will understand the processes better. You will see that SAP Hybris Commerce is not a black box with hidden algorithms and logic under the hood. It is an open system even from the database perspective.

At first, I was shocked by Washington’s architecture (until I saw something normal). Here is an example of the Washington Supreme Court building. From another angle, it’s much prettier, but overall, the architecture here seems somewhat crude, and this picture illustrates the point well. In America, there’s a sort of lack of elegance in everything.
