Fast film (you can see how grainy it is when you zoom in a little) and shooting in full bright sun = you can shoot very short exposure and freeze motion. There were already cameras in the 1930s with mechanical shutters that could do 1/500th and even 1/1000th of a second exposure, which is plenty fast for this type of shot.

The lens looks pretty fast too - depth of field is very shallow, although part of that is also due to possible use of medium or large format - faster lens (lower f stop) and larger film both allow more light capture, and therefore faster exposure as well, but at the cost of less depth of field.

Edit: here is a good print of the full frame - looks like ~1.50 ratio, so probably 35mm film (not medium or large format) - I can't find a lot of information about what cameras Max Alpert used in the 30s, although he did use a 35mm Leica on at least some photos from that era. A Leica III could do 1/1000 in 1935 for example. The early Soviet cameras from the 1930s were also basically direct copies of Leicas. The frame also looks a bit underexposed, which could be due to pushing the exposure for more speed.

You have to realize that popular culture was very tightly controlled and restricted by the Polish communist government at this time. This photo was taken at the Jarocin festival, which was a rare chance to see many bands play that otherwise had no radio play or record contracts and often played styles of music that were viewed with great suspicion by the establishment. Recording these live performances and trading tapes was often the only way people got to hear many of these bands.

I grew up in a neighboring country during this time, but I wasn't much into the rock scene then - I was into folk music, which had a similar scene in my country - many folk artists were straight up banned by the government, so it was impossible to hear them on the radio or buy their records, but tape recordings of live performances existed and were traded among the fans. Same of my favorite music from this period only existed in this form. There were even recordings of shows that got shut down by the police mid-set.

The 80s were a period of economic stagnation in eastern Europe, resulting in a lot of pent up anger and angst in the youth, and at the same time, the establishment was slowly losing its grip on the population. As a result artists were getting increasingly bold in channeling this anger and dissatisfaction, of pushing the boundaries of what was allowed, sometimes crossing them and getting slapped down - but you never knew what could happen at a large gathering of the youth back then - taping was an important tool to document and spread this to the wider population.

Most Polish people would disagree. Poland got pretty fucked in ww2, from all sides, but at least they managed to hold on to some of their sovereignty and not be forced to join USSR as a Soviet Republic.

This partially allowed the democratization movement to form in Poland in the 80s (with Solidarność) and eventually for Poland to get out from under Russia's boot and join the EU and NATO, and avoid the fate of former Soviet Republics like Belarus and Ukraine.

Looks like a JVC RC-660

The guys in the back both have some kind of Grundig - probably C260 or similar.

Here are a bunch of Grundigs as well, also in Poland.

Even more here

Edit: found the same guy as well

Poland was not part of the USSR...

It's a play on this trope

You can have a Linux distro without GNU -Alpine Linux is a popular example

Chinese is also not right - 正确的 (zhèngquè de) means "proper"

Left and Right as the sides are 左 (zuǒ) and 右 (yòu) - you can also add 邊 (biān) to each which means "side" to be more explicit, but they are also used separately in many contexts where the left/right meaning is needed.

The Chinese characters for 左 and 右 actually originated as pictograms of the left and right hand in the early forms of Chinese writing, but later forms both contain general "hand" component (𠂇) with components 工 and 口 added for differentiation

The first computer I used was a PDP-8 clone, which was a very primitive machine by today's standards - it only had 4k words of RAM (hand-made magnetic core memory !) - you could actually do simple programming tasks (such as short sequences of code to load software from paper tape) by entering machine code directly into memory by flipping mechanical switches on the front panel of the machine for individual bits (for data and memory addresses)

You could also write assembly code on paper, and then convert it into machine code by hand, and manually punch the resulting code sequence onto paper tape to then load into the machine (we had a manual paper punching device for this purpose)

Even with only 4k words of RAM, there were actually multiple assemblers and even compilers and interpreters available for the PDP-8 (FOCAL, FORTRAN, PASCAL, BASIC) - we only had a teletype interface (that printed output on paper), no monitor/terminal, so editing code on the machine itself was challenging, although there was a line editor which you could use, generally to enter programs you wrote on paper beforehand.

Writing assembly code is not actually the same as writing straight machine code - assemblers actually do provide a very useful layer of abstraction, such as function calls, symbolic addressing, variables, etc. - instead of having to always specify memory locations, you could use names to refer to jump points/loops, variables, functions, etc. - the assembler would then convert those into specific addresses as needed, so a small change of code or data structures wouldn't require huge manual process of recalculating all the memory locations as a result, it's all done automatically by the assembler.

So yeah, writing assembly code is still a lot easier than writing direct machine code - even when assembling by hand, you would generally start with assembly code, and just do the extra work that an assembler would do, but by hand.

The kids always adapt though.

There is a strong survivorship bias in this though. Some kids do adapt, maybe even most, but many still are harmed, and have been by unhealthy exposure to radio, television, videogames, etc. in the past. Social media is even wreaking havoc in the older generations right now.

It's easy to point at the survivors and the success stories and say see, there is nothing to worry about - but that's also a bit like pointing at the lifelong smokers who do not get lung cancer as an argument against promoting non-smoking.

The history of Taiwan is quite a bit more complex than that, but the PRC (current government in mainland China) has never controlled Taiwan - it was never theirs.

Taiwan was a Japanese colony from 1894 until 1945 when Japan was forced to hand it over to the ROC (the successor government to the Qing dynasty, which was the last time you could argue China controlled the island - the Qing managed to almost fully colonize it before losing it to the Japanese, although a lot of the mountainous parts of Taiwan were still mostly autonomous at that time and inhabited by aboriginal Taiwanese who continued to resist the Qing rule)

The ROC takeover of the island is also seen as another colonization by many Taiwanese as well - the descendants of the Qing era colonists who were mostly Hokkien speakers from Fujian, while the ROC migration in 1949 was mostly Mandarin speakers from wider China, who fairly brutally imposed their rule over the island (see 4 decades of martial law, etc.)

ROC managed to reform itself over time, and Taiwan is now a vibrant democratic country which is forging its new national identity where most people would prefer to be left alone to control their own affairs.
