Android mobergmann • 3 weeks ago • 100%

Why is the exposure time/ shutter speed for my phone capped at 1/2 (half a second)? I would like to take photos with an exposure time of up to 30 seconds. Even when installing other apps, like GCam or Open Camera, it is not possible to increase the exposure time. I have an Fairphone 4 with Android 13. In the screenshot you can see that the exposure time (S) is at the maximum value.  Do you have the same "issue" as me, or know how to fix it?

I am living in Germany and I need some Keycaps, which are not expensive. They don't need to be special, they just need to... work.

What was your beginner keyboard and which keyboard are you using now? It seems, that a lot of people tend to prefer smaller keyboards with layers. I myself am a bit intimidated by them, and would much prefer a somewhat more traditional number of keys, like the Lili58 or the Sofel has (as for now, I think I will get a Lili58). Do you "regret" buying your first keyboard and would have preferred to start directly with your current keyboard (e.g. for saving money), or do you think that your beginner keyboard was necessary/important for you, to get into Spit-Ortho keyboards?

ErgoMechKeyboards mobergmann • 7 months ago • 100%

I want to get a corne keyboard, but I have a few questions, before I dare to dig deeper into the topic. 1. Can I use the keyboard wired and wireless? Meaning, when I plug in a cable, that it (turns of its wireless connection and) uses the cable connection? 2. Can I also just use one site at a time, meaning that the other side is turned off/unplugged? 3. Which version (`corne-classic`, `corne-cherry` or `corne-chocolate`) should I use when I want to use Gateron Hot-Swap Switches (*not* low-profile)? 4. Do I have to pay attention when buying keycaps, e.g. to also get special sized caps?

Czech mobergmann • 8 months ago • 100%

Hi everyone, First off sorry for posting in english, but I don't speak czech. I will be traveling by train from Germany into the Czech Republic (Černý Důl). I was able to book the route to Prague without any problems at the travel center, but I could no longer book within the Czech Republic. I have to travel from Prague to Černý Důl (AFAICT Černý Důl doesn't have a train station, but only a bus stop), but unfortunately I don't know where I can book a ticket or whether I can simply buy a ticket on the spot. I found the website https://idos.idnes.cz, but the prices there are very low at CZK 195 (= EUR 7.85) which sounds sketchy. What advice would you give me about where (website, app, location) and how I should book? Are there any special things I should be aware of, e.g. if I miss a connecting train (German trains are ALWAYS late) what should I do then?

C++ mobergmann • 1 year ago • 100%

I want to free my code from the 5 `std::mutex::unlock` calls per function in favor of `std::lock_guard`. But I have the problem, that I have to keep the mutex locked when entering asynchronous callbacks. Take this code for example: ```c++ std::map<std::size_t, std::set<std::size_t>> my_map; size_t bar1 = ...; size_t bar2 = ...; std::lock_guard guard(my_map); // lock the map my_map[p].insert(10); foo(bar1, [&my_map](const auto& p){ my_map[p].insert(10); // here we can unlock }); ``` `foo` is computing sth and then asynchronously calling the given lambda function and passing a parameter `e` to it. I need `my_map` to be locked the whole time. Keep in mind, that this is just an code example which might not map the real problem, so please don't optimize my given code.
