Watched a documentary there called American Factory where a huge corporation spy’s on its workers to see who’s in a union and find ways to fire those who support it. In school I was also taught that when the mafia was prevalent they were able to corrupt a number of unions. Do you feel any unions in the US are effective nowadays. Here in Ireland we really don’t have a strong union for any industry bar the Luas industry. Often what happens is a small minority in a union for one industry will feel not cared for and will form a new union and send conflicting messages and demands to the employers and government.

> spy’s on its workers to see who’s in a union and find ways to fire those who support it. Haven't seen the movie, but I suspect that they were trying to identify workers who were trying to form a *new* union, rather than workers who were already part of a pre-existing union. It's very common for companies to discourage workers from forming unions, because unions are intended to force changes that benefit the workers at the expense of the company. It is illegal to fire a worker for trying to form or encourage a union, but companies can legally fire workers for all manner of other petty reasons, so union promoters should expect to be under increased scrutiny. Anyway, once the union exists, there's no secret about who's a member. I've never been a member of a union. I've worked alongside union members in various job functions. Some unions are a pain in the ass to deal with, some are not. Some are effective at improving working conditions, some are not. Some are corrupt, some are not.

Some unions prey on the employees that they're supposed to support. Some unions are wildly corrupt. Some are inefficient and obstructionist. Some are mostly good, but made mistakes. And some are pretty great. I was in a union that was corrupt and preyed on their own people. I was offered a job selling insurance to union members where the insurance company deliberately misrepresented itself and the coverage and bribed the union bosses to look the other way (I declined). I'm currently in a great union. If I wasn't working here, I wouldn't believe that a union could be this good, working with the business as a partner, not looking for problems but addressing them when they come up, and defending the employees when needed (which is rare because the business isn't shady).

Would you have to have an older sample too? How's that work? Edit: You guys are very informed in your fields. I'm impressed. A lot of academic communities act aggressively to those that are uninformed. Thank you all for your answers. Almost like I would need a few years to comprehend your discussions adequately. Weird, huh?

No, you cannot see them with standard DNA sequencing. Although egenetic changes do modify the DNA, they do not modify the actual sequence. You can detect epigenetic modifications with techniques such as chromatin IP, bisulfite sequencing, ATAC-sequencing, and Western blotting, among others; the technique you use depends on the precise modification you're interested in and how sensitive you need it to be.

There is the added complication that there may be tissue-specific differences in epigenetic marks, so you'd need to sample across multiple locations (unlike the case for your genomic sequence, which with some exceptions should be about the same in every cell in your body).

~43% of sites worldwide use Wordpress, however 99% of the front end job descriptions I’ve seen never mention Wordpress and instead mention JS frameworks. 1. Why do you think that is? 2.

Because companies don't generally need full time employees to build them a static website, and keep it going. The majority of Wordpress sites are built by design agencies and lone wolf designers, or people doing it themselves. This isn't in any way to denigrate Wordpress or the people that use it, by the way. Far from it. But once a WP site is up, the work of the person designing it is largely done.

Solved: Thank you for your answers, I found perf, gprof, gprof2dot and hotspot, that helps a lot. This tools are available in Linux (Ubuntu/Fedora). \#################### Hi. I don't know how to implement this question. The thing is, I am following some tutorials for developing games with SDL2: Madsycode(youtube), Limeoats(youtube), Pikuma(was in Udemy, now he has his own page). * One of the many things that I like in the Pikuma tutorial, is that the programs is so lightweight, ECS, integration with Lua. * In the Limeoats, I like that you can print with animations tilemaps and some physics. * With Madsycode, I like the organization of the code. ​ This is each game running and measuring using htop, bpytop, btop. | SDL | threads | RAM | CPU | | ------ | ------- | --- | --------------- | | Mad | 12 | 79M | (2.5 to 3.5) | | Lime | 11 | 69M | (1.9 to 2.6) | Pikuma doesn't measured because its the lighter :D **But,** comparing Mad and lime, the consume are almost similar. Is there a way to know which thread/method/function is consuming more? Or, Which method do you use for lightweight your program?

For windows, I love perfview. Steep learning curve though but it will serve you well to invest the time.

It's required for certain government or government contractor jobs. However, (in the U.S. at least), you can't just get a clearance if you want one. You require a reason and a sponsor for the clearance. That means you can't get a security clearance until you have landed a job that requires one.

Already having been cleared in the past is gets you a pretty good leg up on other applicants, and being eligible at all opens up opportunities in a smaller applicant pool than if you aren't, in aerospace (and other military contractors, but the big ones that are hiring in droves are the aerospace people). But you either already have one or you don't. It's not like you can just apply for one.

Hey guys, I am a soon to be physics grad, and while I have always enjoyed coding I do think I am a core science at my heart. So why programming? Because I need the money to sustain myself and pay my way through a masters, which can be quite expensive. Also, I need a break from physics for a while. Also can't stay with my parents no more. Bunch of stuff. So I wanna know which programming language should I focus and learn in the next 6 months in the hope of landing an alright job. I can program in python, C++ up until linked lists etc., and I have a solid understanding of control flow for most languages, and thus my confidence that I'll understand most languages. Also, the answers will help me get a nerve of what the programming world looks like right now and what is in demand. Any and all suggestions/criticism welcome. ​ PS: I'm in the UK if that helps.

What the heck does “up until linked lists” mean? That you can’t write code more complex than a linked list? Read it? Understand it? Also, how are you even defining “more complex”, if that’s even what you meant? And, “good understanding of control flow”? I’m no physicist, but sounds like to me: “I have a good understanding of F = ma. What does the particle physics market look like, and what kinda job can I get at CERN??”

I've made a small CLI program in python that solves a problem for me, and could be useful to others. It takes a .json file and converts an array within it to a csv to be edited, then you can send the csv back to overwrite the original array with the new key value pairs in the csv file. There's a few other minor things, but that's the gist of it. Now, I would like to monetize it. This script solves a problem I have with software that's $500/year, so I feel I can sell a few of these. Problem is, I'm not sure how to go about it. About me, I've published an android app in kotlin. I'm relatively familiar with kotlin and a little of python. I could probably pickup enough java quickly to get it done there. I've tried using tkinter to build a gui in python, but it's turning out to be way more work than I expected, and I don't know how I could monetize an .exe without having users just share the executable, circumventing having to pay for it. I would like to avoid having to manage my own backend for validation (hence using google auth). I thought of creating a web app that uses google authentication, but I can't find much information about how to do that (perhaps I am not looking in the right places... I don't know what I don't know, you know?) I've used apps script extensively to automate and log data (from g-services as well as rpi's). I guess my question is, how would you do this? It needs to accept a file from the user, ask some questions, generate a new file with that information, and spit out that different file to the user. I'm open to learning some of a new language if it's going to be easier, but would like to stick with kotlin/java/python if possible.

Open source it, put it up on github, use it as motivation to either get a higher paying job or a better increase from your employer. Profit!

Quite frankly, this sounds like the kind of quick script that folks bang out every day. However, does this accomplish something that is critical to whatever processes the workflow involving the licensed software requires, and is it something that would normally be done many times during a given project? If so, the simplest approach would be to build the functionality into a webapp, using a framework that supports authentication (Laravel, etc), and can be integrated with a payment processor (Square, etc). If the solution you provide is cost-effective, you *might* make something from it. No harm in trying. By building a webapp, instead of a standalone application, you don’t have to worry about space pirates.

Let me give some example: int a = 3; #ifdef a cout << a; #else cout << (++a); #endif With the printed result `4`. Based on this example, I assume that preprocessor symbols are not the same as postprocessor symbols, AKA the `a` in `#ifdef a` isn't the same as the `a` in `int a = 3;`. I make this assumption, because if they were the same, I would assume `#ifdef a` to be a branch that is hit rather than missed. But evidently it missed. So in order to test that assumption, I make a new example: #define a int a = 3; #ifdef a cout << a; #else cout << (++a); #endif Since I believe the two `a`s to be separate, I expect this to compile. It does not. So now I have evidence both for and against the idea that these two symbols `a` are the same. ​ Somebody please tell me what the hell is going on here, I don't understand.

The pre-processor is an entirely separate language applied to the source text before the C++ compiler sees it. The preprocessor macros are independent of the language identifiers. In the first example, there is no `a` preprocessor macro defined, so the `#ifdef` branch is elided from the source text as seen by the compiler and it sees: int a = 3; cout << (++a); And thus prints out `4`. In the second example, you've defined a preprocessor macro `a` to be an empty string. The preprocessor spits out the text: int = 3; cout << ; Which will not compile.

Why are there multiple programming languages?

We've been designing programming languages for about 70 years, and have learned a thing or two in that time. Following from that, researchers like playing with new ideas, and sometimes they catch on outside of an academic context too, and a new language is built around the new idea. Languages have trade-offs. One well-suited for one purpose may be poorly-suited for other purposes.

I only made a `bidirectional iterator` once before and that was for a `list` a long time ago. So I am uncertain how to do it for a `map` now concerning the `member typedefs` of `std::iterator_traits<It>`. If I am doing `template <tyename K, typename v>` where K is the `key` and V is the `value`, then would this ok for the `member typedefs`?: template <typename K, typename V> struct Iterator { using value_type = V; using difference_type = ptrdiff_t; using pointer = V*; using reference = V&; using iterator_category = std::bidirectional_iterator_tag; }; Thanks

`value_type` for associative containers is generally `pair<const Key, Value>`, with everything else following from that. //edit: In case your map type does not store its nodes in a pair, you could consider something like `pair<const Key&, Value&>`.

It's called Fractional Orbital Bombardment system. It does require a missile designed for it. The delta V (change in velocity) requirement is higher than for an ICBM, so it needs either a more powerful missile or/and a lighter warhead, and the missile needs to perform the reentry burn meaning there's different control requirements after the boost phase. Edit: Or just orbital bombardment if the missile loiters in orbit for ages. Doing that with nuclear warheads would break international treaties.

I’m the 51 year old tech support manager for an office of lawyers ranging in age from late 20s to early 70s. In my experience, no one hates any and all technology like a 35 year old lawyer.

For myself, I’ve always been a techie guy, but I don’t like a lot of the ways that’s technology is progressing. I don’t like when things are hidden from me in the interest of making them easier to use. I don’t like how everything wants to tie me down to monthly fees. I pay monthly for Adobe Photoshop and Lightroom, which means that as soon as I stop paying, my photo libraries become useless. I subscribe to Apple Music, which is super convenient, but as soon as I stop paying I no longer have any music. If I were to “buy” a movie from the Google Play store, do I really own it? What if they scrap the store like they did with Google Music? I don’t like the massive harvesting of personal information. I don’t like ads everywhere. Instagram is now showing a “personalized” ad for every 3 pictures. I miss buying something like an new CD player or vhs player, buying some tapes or CDs, and just playing them. If the thing breaks, I can get it fixed and use it until the tapes wear out. No license agreements, no giving them my email address or phone number, not having to opt out of sending usage statistics to “improve my experience”. Just leave me alone.

Can decompression sickness cause pneumocephalus (air in the cranial cavity)?

I don’t think so: * decompression sickness (DCS) doesn’t cause \*air\* anywhere, only nitrogen * nitrogen equilibrates between environment, lungs and blood relatively slowly (compared to oxygen and CO2): DCS is caused by an imbalance between higher tissue concentrations and lower ambient (partial) pressures - nitrogen bubbles then form, best pictured by all the bubbles appearing in fizzy drink when opened. * these bubbles will form where tissue nitrogen concentrations are highest. This can be in general tissues, but is usually within plasma, liver and muscle. They therefore form within the blood vessels rather than as free gas within the brain or CSF. Although the latter is possible I think neurological DCS is still a manifestation of circulatory dysfunction secondary to bubble formation, not direct formation of bubbles in neurological tissue. This is Reddit so I could be wrong, but the basics will be sound so the answer is likely to be ‘no’

Hey now, let's put some respect on Miss Columbia's name why don't we She was a girlboss throughout the 1800s/early 1900s until she was unfairly killed off by the world wars and the "need" for a masculine personification In political comics, she was always a better personification (as was shown to care more about justice/equality/democracy) than Uncle Sam. She was used to represent the American people while Uncle Sam was used to represent the federal government. Eidt Of course, the answer to this question can be answered by Hetalia

(Sorry I know this is a cpp subreddit but c seems to be inactive) The following is intended to print out statements but in different lines: #include <stdio.h> int main(){ printf("Hello World!"); printf(" "); int number= 1; float percentage= 3.14; char letter = 'A'; printf("This is the number: %d", number); printf("This is the percentage: %f", percentage); printf("This is the character: %c", letter); return 0; } However, it all prints on the same line. Output: Hello World! This is the number: 1This is the percentage: 3.140000This is the character: A I also tried doing it so that it prints the percentage sign on line 12: printf("This is the percentage: %f%", percentage); but I got an error, what can I do? I am coding on Ubuntuu text editor, using terminal to run my code, and an online compiler. Both print on the same line.

printf doesn't automatically add a newline. u need to add `\n`, ie `printf("hello\n")`. for the percent sign you probably need to escape it since it is a special character. Try `printf("This is the percentage: %f\%", percentage);`

Is isolationist sentiment on the rise? Do you think it will continue to grow?

Yes, on both sides of the political spectrum but for different reasons. Republicans are saying other countries have taken advantage of the USA, that they're not paying their fair share to our commitments, and we shouldn't be spending money on foreign aid that could be going to Americans here. Democrats are saying we shouldn't be intervening in other countries affairs, that we have a history of destabilizing and overthrowing governments that don't follow our orders, and that we shouldn't be telling other nations how to live when we have a myriad of issues at home we should be focusing on. Both sides essentially want isolationism, their reasoning for it differs a little though. But what will ultimately win out in politics is business interests and business interests benefit more from our global position than they would an isolationist one

Evidently there is sulfur and oxygen in magma and it combines to form SO2. What magma chemistry leads to this being a primary constituent of volcanic eruptions?

You answered your question pretty well in asking it: It's a major volcanic emission because sulfur is in solution in magma. There's a fair amount in the earth in general, and it ends up in most magma in some amount, just like silicon, iron, aluminum, calcium, and sodium. When the magma cools, near the surface in the case of a volcano, the sulfur is one of the last things in the liquid magma to be in an 'active' state (I think it's technically a superfluid under these conditions, but it might just be a gas dissolved in mostly solid rock?). This sulfur escapes through micro- or macroscopic cracks (or the bubbling surface of a lava lake or flow, or mixed with ash and CO2 and water in an explosive eruption) and reacts with air to form sulfur dioxide.

Would the blood be ‘tainted’? Could it potentially get someone sick? Asking out of curiosity all I could find online is “don’t donate until one week free of symptoms”.

First up, respiratory viruses are not known to be transmitted through blood transfusions. This was confirmed many times during Covid-19. Respiratory viruses mostly live in cells in your airways, they aren't in your blood stream. Even then, not a problem for the recipient (mostly) due to how donated blood is processed. Let's specifically look at *whole blood* donation in wealthy countries. Your individual donation is often these days mixed in with a lot of other people before any testing. It all depends on the centre that does the collection and company that does the processing. But let's assume individual testing. It is tested for blood groups, red cell antibodies and then a handful of blood borne infectious diseases such as HIV, hepatitis, syphilis, HTLV, CMV and malaria if you checked that box. Others too depending on where you live. Worth mentioning that even those are removed in later processes by washing. More on that below. Your blood is then broken down into it's components using a centrifuge. Red blood cells, plasma, or platelets are extracted using specialised machines. There are also special detergents and soaps to remove viruses or proteins that are not wanted. This is called [blood washing](https://en.wikipedia.org/wiki/Washed_red_blood_cells). It's rare these days to get given a packet of blood that was taken directly from the host without processing. Any cold viruses will be removed by washing. They aren't there, but if they were somehow, they are removed. From [the WHO website](https://www.who.int/news-room/fact-sheets/detail/blood-safety-and-availability): 37% of the blood collected in low-income countries is separated into components, 69% in lower-middle-income countries, 95% in upper-middle-income countries, and 97% in high-income countries. Your two main concerns not addressed above are * Allergic reactions to proteins and/or cells in the transfusion (not related to colds) * Fever due to special proteins called *cytokines* in the transfusion. These reactions are called febrile nonhemolytic transfusion reactions (FNHTRs) (related to colds) Cytokines are special proteins you make to trigger your immune system. You can think of it as you get a respiratory virus, your body then sounds the alarm (cytokines) to make an immune response. After a transfusion the host body is confused at why the alarm is sounding so it starts an immune response just in case. Important note: the host doesn't have an infection, their body is responding as if it has. Partly, we don't need a patient starting an immune response when they already under stress for whatever reason they need the blood. However, the trauma requiring a blood transfusion is probably so serious that a fever is least of their problems. Mostly, *we want you to wait for your own health*. After a cold your body is stressed and we don't want to cause you harm too. Your blood volume is higher in white blood cells, but not a problem as all those white blood cells will be removed and thrown away / turned into products. Fun fact: the preferred process to dispose of waste human blood is to pour down the regular domestic sewer drain for disposal. This is completely legal and safe. Should a blood processer decide a batch is (1) too old and unusable or (2) contaminated in some way that it is too expensive to purify or (3) too much was collected, they will pour it down the drain.

Would the blood be ‘tainted’? Could it potentially get someone sick? Asking out of curiosity all I could find online is “don’t donate until one week free of symptoms”.

It's actually....really, really bad if a cold virus gets from your nose/throat/lungs to your blood. Sometimes your digestive tract gets infected, too, but a typical cold infection would leave various *markers* of the infection, from white blood cells etc going to the linings of your airways and other immune processes on-site, but hypothetically no living cold virus. The rules are to be careful in the 0.1% (or some other very small percent) of cases where that isn't the case, and someone vulnerable gets REALLY sick. EDIT: thought about this some more. I think there may be active virus in your blood with a 'normal' cold, but not at concentrations where it can successfully start infecting more of your cells elsewhere in your body. One problem they hope to avoid is that your blood might go to someone with next to no working immune system who could get a systemic infection from a tiny viral load in donated blood. I think. Folks who aren't the nerd kid of two nerd nurses feel free to weigh in.

You can check [numbeo.com](https://numbeo.com). Retail sites also often ask you to enter to your ZIP code.

I used to spend a lot of time in India and I was always surprised at how much sex you guys think goes on here. Like, I used to check into hotels with my wife and they would assume that we were casual friends who were sleeping together (They would say things like, "So, I assume a one-bed room for you and your... Friend?"). We were wearing wedding bands and everything, although I guess culturally that's not always how you guys represent marriage over there huh? Anyway, I used to get the distinct impression that a lot of people in India think that way about America because of our TV shows. Sit-coms like Friends and stuff. There is definitely more causal sex in America than in India, but certainly not as much as those TV shows make it seem. Kind of like how a bunch of Indian soap operas make it look like everyone has a ton of money and lives in really nice houses, and wears a ton of gold jewelry everyday? Similar in America.

You can return strings, exactly like that. Your problem is somewhere else. 1. `struct {...} note;` is a terrible idea. Unnamed types are very rarely useful. 2. Don't use `using namespace std;` 3. Don't use (mutable) global variables 4. `for(int i=num1; i <= str1.length(); i++)` is going out of bounds for `str1[i]`. 5. `note[0]=str1[i];` Are you sure you want to overwrite the first char over and over? 6. Why are you using floats? You're using double literals for the calculations anyway so even if you had a reason to use floats (and you don't) it would be screwed up at that point. 7. You need to `#include <string>` if you use `std::string` and `std::getline`. 8. Why do you hate whitespace that much? Code is way more readable if you put spaces around operators. 9. Why are you writing things to file just to read them again? Just use the data directly and then write to the file at the end if you have to save it.

The function certainly returns a string. But the question is what string? What do you want the function to do? I don't think it does what you want: currently it returns a string which consists of a single character which is the last character of the input argument `str1` unless `num1` is equal to or larger than the length of `str1` in which case it just returns a string with a space: " ". Also the variable `pos1` is completely unused. I don't know what the function is supposed to do, so I can't really help you more than that. Here are some other suggestions for improving your code in general: You are using old C-style declarations of structs - don't do that, do: struct note { string fach; float maxP; float yourP; float note; }; (notice position of name `node` should immediately follow `struct`) Don't use global variables (except for global constants)! Just don't! This is a bad practice that will quickly lead to errors. Instead declare and define them in the scope/function where they are needed - in your case you can move the definition of `mid`, `line`, `notes` and `s` into the `main` function. Use (long) descriptive variable names. In three hours you have already forgotten what `mid`, `s`, `num1` and `pos1` refer to. Use *descriptive* names: `do_save`, `start_index` etc. Enable all (or almost all) warnings for your compiler. If you're using Visual Studio you can use `/Wall` or `/W4`, on gcc/clang you can use `-Wall -Wpedantic -Wextra` Ensure that you use an IDE (like Visual Studio or CLion) or a Text Editor that can show code hints, auto-completion and compiler warnings.

Why not just use plates?

Food safety laws are different in every state, but in mine (California) and I assume in many others, the major benefit is cleaning time. Baskets do need to be washed/disinfected, but considering there's rarely any actual food on them once the liner is thrown out, doing so is very fast and easy. They also stack easily, are less prone to breaking, and cheaply replaceable, theres also time saved on the serving end of things, if you have waiters who clean the tables, its much faster to dump a basket out than it is to scrape a plate off, or if you rely on customers to return their baskets on their own, you save time having front of house staff put away dishes, and they can focus on cleaning tables/seats instead. The restaurant I work at personally serves items like burgers, chicken strips, and fries in baskets, while most of the rest of the menu is served on plates and bowls. I also happen to be the dishwasher during closing shifts, we run a dish-pit with no machine, which means every item is hand rinsed, soaked, and sanitized by yours truly. the difference in time that it takes me to wash 50 baskets vs 50 plates is immense.

I wanted to ask you all if this timeframe will be enough to cover the entire course or should I consider self-studying to give myself more time to prepare and then do an online certification exam? Also, what are my odds of passing the certification exam if I self-study? Your thoughts and opinions will be helpful. Thank you.

The fact that spaces are important in syntax and how easy it is to overlook an error because of just a space!? And the code itself looks like it was written by an alien.

Like Bash, Perl is a bit of a syntax bastard

Well OP, just wait for the fun you’ll have with whitespace when you use YAML 😂 I guess PHP and people still using JSP or whatever that ancient Java thing was gives me heebies jeebies, but I generally avoid these things 😛

Our project is compiling with C++17 at the moment and we consider moving up to C++20. We compile to Windows only at the moment, but the issue is that it is very likely that we will have to port it to MacOS and Linux in the future (let's say it for sure won't happen in the next 6 months) I know that gcc and clang are lagging behind MSVC when it comes to C++20 support, but assuming we stay away from modules at the moment, anyone has an idea of how likely are we to encounter incompatibilities between MSVC/gcc/clang? (i.e code that compiles in one compiler but fails to compile in another due to a bug or a feature that is not yet fully supported)

https://en.cppreference.com/w/cpp/compiler_support/20 So basically modules and std::format are not portable right now, have fun with the rest.

I know it is more of a QoL thing since you can just achieve it through telling everyone on the team to not use it, but it would be very helpful in a codebase touched by many people.

You probably can't within the language. The reason is that `int32_t` is very often just something like `typedef int int32_t;`. Things like [std::is\_same](https://en.cppreference.com/w/cpp/types/is_same) also [think they're the same type](https://godbolt.org/z/v15fv5Mo1). You probably need some compiler-specific stuff if it's even possible.

Id install [git hooks](https://git-scm.com/docs/githooks) to ensure nothing with `int` can be pushed

There is no way to do it within the language because the type system does not distinguish between them — `int32_t` is simply a typedef for (typically) either `int` or `long`, meaning they are exactly the same type. That said, there are external tools that can do this for you. I believe there is a clang-tidy rule to enforce this style, for instance. It would be nice to get that as a built-in (optional) compiler warning.

I've been working as application support/developer for the last 15 years, and now that I've turned 40, I've found that I am no longer able to effectively deal with the random incidents and major outages, that I used to be able to shrug off and deal with when younger. I'm worried the crushing stress from trying to get a major production system back online during an outage might be affecting my health in potentially dangerous ways now. As such, I was wondering what, if any, alternative jobs I could consider moving into, that didn't come with the fortnightly all-day MIM/bridge/customer-yelling/panic attack merry go round? I'm just looking for ideas at this point :)

You could move into project management? You have the tech background and it’s not firefighting.

Security is an option. Compliance is nice in that aspect, you come in to work, tell everyone how they are doing everything wrong and leave while they stay and fix. There are other parts of security that don’t deal with incidents as well. Your previous experience is a big advantage when working security as well.

Hi ! I'm having trouble implementing firebase in an iOS app using cpp... I hope you'll be able to help me ^^' Here are the three troublesome files : First, the listener interface from firebase : class Listener { public: virtual ~Listener(); /// Called on the client when a message arrives. /// /// @param[in] message The data describing this message. virtual void OnMessage(const Message& message) = 0; /// Called on the client when a registration token arrives. This function /// will eventually be called in response to a call to /// firebase::messaging::Initialize(...). /// /// @param[in] token The registration token. virtual void OnTokenReceived(const char* token) = 0; }; Then, my own listener for iOS, h file #ifndef NotificationHandlerIOS_hpp #define NotificationHandlerIOS_hpp #include "NotificationHandler.h" #include <iostream> #include "firebase/messaging.h" struct NotificationHandlerIOS : public firebase::messaging::Listener { ~NotificationHandlerIOS() override; void OnMessage(const ::firebase::messaging::Message& message) override final; void OnTokenReceived(const char* token) override final; }; #endif /* NotificationHandlerIOS_hpp */ And finally, the cpp file #include "NotificationHandlerIOS.hpp" #include "NotificationHandler.h" #include <iostream> void NotificationHandlerIOS::OnMessage(const ::firebase::messaging::Message& message) { qDebug() << message.raw_data; } void NotificationHandlerIOS::OnTokenReceived(const char* token) { qDebug() << token; NotificationHandler::GetInstance()->RegisterToken(token); } Now, the fun part, the error : Unimplemented pure virtual method 'OnMessage' in 'NotificationHandlerIOS'

altho i learned C/C++ , pointers , OOP design , etc in school but everything i do in job i ve learned on my own during summer breaks or weekends . Go , React , Git , docker to name a few and i believe that this is the case for most of my classmates if not for everyone who works as SWE , it's true that school taught me a lot of things but i just don't use IAbstractAbstractFactory nor all those OOP heavy design patterns that i had been taught in univ . so what's the real difference between Self-taught and CS grad if they both taught them selves frameworks and languages (we talking about normal web stack not all those data eng,low level jobs ) ?

Kind of. Without a traditional CS education - you can go a whole career without understanding the likes of path finding algorithms, OS internals, distributed synchronization primitives, etc so you aren’t forced to learn those things by the industry. However, understanding these concepts will make you a better software engineer and will give you the right intuitions to make sound engineering decisions.

IME, the difference between self-taught programmers and formally taught programmers mainly boils down to whether someone else forced them to put some uncommon tools in their “mental toolbox”. Those tools aren’t always used every day (if they were, self-taught folks would learn them), but they are useful occasionally and are necessary to efficiently tackle some types of problems (which are fortunately somewhat uncommon in actual business products). TL;DR: it’s hard to know what you don’t know, so if you teach yourself without getting feedback from someone who knows more, you tend to end up with gaps around the difficult/uncommon topics.

I was surprised to see that Sag A* changed in such a short timescale. What's the time resolution you can achieve? I guess you can't image events shorter than one hour or so. What's the limiting factor? Can a image taken over a shorter length of time become less blurred, or is the optical resolution the cause of the blurriness of the image of Sag A*?
