C - i++ not working inside a while loop
So, I'm helping a friend with her programing class, and we've come across something funny. I have the next code: void ingresardatos(struct alumno *lista){ int i=0; char continuar='s'; while(continuar=='s' && i<20){ printf("Valor de i al iniciar: %d \n", i); printf("Introduzca el nombre del alumno:\n"); scanf("%s",&(lista[i].nombre)); printf("Introduzca la matricula:\n"); scanf("%s",&lista[i].matricula); printf("Introduzca la primera calificacion:\n"); scanf("%f",&lista[i].calf1); printf("Introduzca la segunda calificacion:\n"); scanf("%f",&lista[i].calf2); printf("Introduzca la tercera caificacion:\n"); scanf("%f",&lista[i].calf3); lista[i].prom=(lista[i].calf1+lista[i].calf2+lista[i].calf3)/3; if(lista[i].prom<=5.9){ strcpy(lista[i].nota,"NA"); } else if(lista[i].prom>=6 && lista[i].prom<=7.3){ strcpy(lista[i].nota,"S"); } else if(lista[i].prom>=7.4 && lista[i].prom<=8.6){ strcpy(lista[i].nota,"B"); } else if(lista[i].prom>=8.7 && lista[i].prom<=10){ strcpy(lista[i].nota,"MB"); } printf("Valor de i antes: %d \n", i); i++; printf("Valor de i después: %d \n", i); printf("¿Desea continuar? (S/N)"); scanf("%s",&continuar); } } It's supposed to be a grade list for a class of 20; you introduce the student's data until you press "n", and it saves them on a list. Now, I figured out the pointer part (I just really know Java, so it's kinda weird working on C), but what I can't figure out is how to make the i++ part work. If you run it like it is, it'll start with i=0 on the first pass, then go through all the code, and finally do i++ before asking if you want to continue (it prints it on the screen). But then, when you press "s" to indicate you want to continue, it'll start with i=0 again, and for the life of me I can't figure out why. I tried i++, ++i, i=i+1, and so on, but nothing seems to work. I even tried making i a pointer, but Windows didn't like it and crashed my program everytime I ran it. If someone could explain just why it isn't working, I'd be eternaly greatful. I've been at it for days now, and I can't figure it out.

How does global error handling work in service workers?
<p>I found <a href="https://developer.mozilla.org/en-US/docs/Web/API/ServiceWorkerContainer/onerror" rel="noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/ServiceWorkerContainer/onerror</a> which says:</p> <blockquote> <p>The onerror property of the ServiceWorkerContainer interface is an event handler fired whenever an error event occurs in the associated service workers.</p> </blockquote> <p>However I'm not able to get this working in Chrome (v51). In the scope of the main application, I ran the following code from the console:</p> <pre><code>navigator.serviceWorker.onerror = function(e) { console.log('some identifiable string' + e); }; </code></pre> <p>Then within the scope of the active service worker I triggered an arbitrary error:</p> <pre><code>f(); // f is undefined </code></pre> <p>The result was the usual "Uncaught ReferenceError: f is not defined(…)" error message but it was not logged through my global onerror handler.</p> <p>The MDN page says that this API has been supported in Chrome since v40, but <code>navigator.serviceWorker.onerror</code> is initially undefined which leads me to believe that it's unimplemented.

Getting the first paragraph of wikipedia, and storing it into a text file
I wanted to make a system in which we give something to be search onto the terminal of a Raspberry Pi and the Pi gives a voice output. I've solved the text-to-speech conversion problem using pico TTS. Now what I wanted to do is go to the Wikipedia page of the term to be searched, and store the _first paragraph_ of the page to a text file. For example, the result for input [Tiger][1] in Simple English should make a text file containing - **The tiger (Panthera tigris) is a carnivorous mammal. It is the largest living member of the cat family, the Felidae. It lives in Asia, mainly India, Bhutan, China and Siberia.** [1]: https://simple.wikipedia.org/wiki/Tiger/ "Tiger"

How to restore state in an event based, message driven microservice architecture on failure scenario
<p>In the context of a microservice architecture, a message driven, asynchronous, event based design seems to be gaining popularity (see <a href="http://blog.christianposta.com/microservices/why-microservices-should-be-event-driven-autonomy-vs-authority/" rel="noreferrer">here</a> and <a href="https://www.nginx.com/blog/event-driven-data-management-microservices/" rel="noreferrer">here</a> for some examples, as well as the <a href="http://www.reactivemanifesto.org/#message-driven" rel="noreferrer">Reactive Manifesto - Message Driven trait</a>) as opposed to a synchronous (possibly REST based) mechanism.</p> <p>Taking that context and imagining an overly simplified ordering system, as depicted below:</p> <p><a href="https://i.stack.imgur.com/Xtttg.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Xtttg.png" alt="ordering system"></a></p> <p>and the following message flow:</p> <ul> <li>Order is placed from some source (web/mobile etc.)</li> <li>Order service accepts order and publishes a <code>CreateOrderEvent</code></li> <li>The InventoryService reacts on the <code>CreateOrderEvent</code>, does some inventory stuff and publishes a <code>InventoryUpdatedEvent</code> when it's done</li> <li>The Invoice service then reacts to the <code>InventoryUpdatedEvent</code>, sends an invoice and publishes a <code>EmailInvoiceEvent</code></li> </ul> <p>All services are up and we happily process orders... Everyone is happy. Then, the Inventory service goes down for some reason 😬</p> <p>Assuming that the events on the event bus are flowing in a "non blocking" manor. I.e. the messages are being published to a central topic and do not pile up on a queue if no service is reading from it (what I'm trying to convey is an event bus where, if the event is published on the bus, it would flow "straight through" and not queue up - ignore what messaging platform/technology is used at this point). That would mean that if the Inventory service were down for 5 minutes, the <code>CreateOrderEvent</code>'s passing through the event bus during that time are now "gone" or not seen by the Inventory service because in our overly simplified system, no other system is interested in those events.</p> <p>My question then is: How does the Inventory service (and the system as a whole) restore state in a way that no orders are missed/not processed?</p>

How to properly set line height for Android?
<p>I am a UX architect working with a team of Android developers that are mostly junior. We are having issues properly setting line height in Android. </p> <p>We are using the Material Design spec as our guide for our app. In particular, you can see line height specs here:</p> <p><a href="https://material.google.com/style/typography.html#typography-line-height" rel="noreferrer">https://material.google.com/style/typography.html#typography-line-height</a></p> <p>Let's use Body 2 as our example. The spec says the type is 13sp or 14sp, and the leading (line height - same thing) should be 24dp. </p> <p>Here's the problem: these devs are telling me there is no such way to set line height like that in the code. Instead, they are telling me to measure the distance between the two lines of text and give them that measure - let's say it's 4dp. They want this for each style of text we are using. </p> <p>We are using a Sketch > Zepelin flow for spec. </p> <p>It seems odd to me to be able to create a font style (which could easily be class/style in the code) that is 13sp with 24dp leading, and not be able to set the leading, but instead have to add a 3rd measure to the mix. There is no place in Sketch or Zepelin for such a measure "between lines."</p> <p>Is this really the way it is done, or is there a proper way to set line height? </p>

Can you set rounded pixel corners in Photoshop?
<p>I'm making a pixel art that's why my canvas is only 30x60 pixels, and I don't think using a rectangle shape will work because the canvas is just too small and I only need one pixel to have a rounded corner.</p>
