Verkürzte Aufmerksamkeitsspanne kann schnell den Spielspaß zerstören. Da haben wir uns gerade an ein großartiges Game gewöhnt, da kommt schon der nächste Hit, den wir unbedingt zocken wollen. Und schwupp, haben wir das vorangegangene Spiel vergessen und kommen nicht mehr in das Gameplay rein. Der Spaß eines Spiels hängt stark von der erlernten Spielmechanik und der erfahrenen Spielstory ab. Welche Möglichkeiten gibt es bei der Spielentwicklung, die Erinnerung an das Spiel frisch zu halten oder zurückzuholen? Diese und andere Fragen beantworten wir in der heutigen Q&A Folge. Die Themen: Wie verhindert man das Vergessen, wenn ein Spiel mit Pausen gespielt wird? Wie oft darf man spielrelevante Information wiederholen ohne das es nervt? Wie sieht ein gutes Tutorial aus? Wie baut man eine funktionierende Ingame Economy auf? Wie unberechenbares Spielerverhalten Ingame Währung lahmlegen kann. Steamdeck und Co. Muss man seine Spiele mehr an Handheld PCs anpassen? Wann sollte man das Marketing für Spiele starten? Wo sollte man das Marketing-Budget investieren? Und: Macht Marketing NACH dem Release Sinn?

Memory leaks occur when a program allocates memory and fails to free it when the memory is no longer being used. They can cause the memory use of a program to balloon over time, eventually leading to performance problems or a crash. They are a common programmer error, that has been alleviated, although not eliminated, by modern programming languages. Programming languages like C and C++ use manual memory management, which requires the programmer to do some book-keeping. The programmer must keep track of all of the memory they allocated and must remember to free it. Programming languages with garbage collectors automatically free unused memory. In this episode we explain memory leaks and look at a recent case of a major memory leak in macOS Monterey as an example. Show Notes Episode 76: What is Protected Memory?

Rumors and leaks suggest that Apple's 27-inch iMac is next in line for an M1 Pro upgrade, as the company continues its two-year transition to Apple silicon. Earlier this year, Apple updated its 24-inch iMac with an M1 chip. Recently released Pro-level MacBooks received new M1 Pro and M1 Max chips, and it's expected that this new iMac will receive the same treatment. The new iMac, which Apple will reportedly release in early 2022, may include features present in the new MacBooks, such as mini-LED screens and ProMotion displays. And speaking of MacBooks... Users of the new M1 Pro/M1 Max MacBooks have reported memory leak issues, with some apps using a lot of RAM. Macworld executive editor Michael Simon and Computerworld executive editor Ken Mingis join Juliet to discuss their experiences with memory leak on their MacBooks, plus how Apple could fix the problem. They also discuss the potential new iMac, including what features it could have that would differentiate it as a Pro-level device.

Ubicuo y poder editar ficheros de forma remota. Uso del teclado en vez del ratón. Emacs: https://es.wikipedia.org/wiki/Emacs. [19:22] Operador morsa (walrus). Sigue usándose muy poco. Python va complicando la sintaxis más y más. Se habló en una tertulia anterior. Jesús solo ha encontrado este caso útil: Pasar de: buf = f.read(1000) while buf: [Hace el procesamiento] buf = f.read(1000) A lo siguiente: while buf := f.read(1000): [Hace el procesamiento] [25:57] Erratas en tertulias anteriores: Migración de Python a Github fue en 2017. No es "Steering committee" sino "Steering Council". [27:02] Pablo Galindo forma parte del "council" tras las últimas elecciones. Charla de Pablo Galindo en la PyconES 2019 sobre el mundo de los Core Developers de Python: https://www.youtube.com/watch?v=qcvZOaY1emk. Algunos proyectos Python están usando Rust. Por ejemplo: https://cryptography.io/, con cierta polémica. Mercurial también usa Rust https://www.mercurial-scm.org/. Las variables locales pueden ser modificadas a través de su "closure", en funciones hijas o en otros hilos. Es una barbaridad, pero la posibilidad existe. Esto es lo que hace, por ejemplo, un debugger. [35:37] ¡Spoiler sobre la resolución del "Memory Leak"! Issue35930: Raising an exception raised in a "future" instance will create reference cycles https://bugs.python.org/issue35930. Traceback: https://docs.python.org/3/library/traceback.html Frame: https://docs.python.org/3/library/traceback.html#traceback.FrameSummary. Stack: https://docs.python.org/3/library/traceback.html#stacksummary-objects. [39:17] Usar una técnica similar para detectar las características de quien te llama para poder mezclar de forma más limpia código síncrono y asíncrono. Biblioteca Unsync: https://pypi.org/project/unsync/. [41:32] Sigo explicando detalles de la solución del "Memory Leak". Issue35930: Raising an exception raised in a "future" instance will create reference cycles https://bugs.python.org/issue35930. Estamos continuando una conversación que ha durado varias tertulias. Jesús Cea pone un ejemplo de cómo generar un ciclo con una excepcion. La caja y media de cervezas se las lleva... ¡Jesús! [47:22] No se está conectando gente desde Hispanoamérica. ¿Por qué? [50:07] Más erratas: Los "tracebacks" NO son inmutables. [50:32] Nuevo método "with_traceback()" a la hora de crear excepciones: https://docs.python.org/3/library/exceptions.html#BaseException.with_traceback. Puedes generar una excepción con un "traceback" arbitrario. El caballo de batalla del bug es que el "future" https://docs.python.org/3/library/concurrent.futures.html levanta una excepción y esa excepción debe "transportarse" a otro hilo. Explicando cómo se visualizan los "traceback" si un "future" https://docs.python.org/3/library/concurrent.futures.html muere con una excepción. def a(): 1/0 try: a() except Exception as e: raise e Traceback (most recent call last): File "", line 4, in File "", line 2, in File "", line 2, in a ZeroDivisionError: division by zero Cuando un "future" https://docs.python.org/3/library/concurrent.futures.html lanza una excepción, se ven "frames" repetidos. Hay varias formas de solucionar el bug. Ahora hay que pensar en cual elegir, que sea la más simple e intuitiva. [01:01:52] Sobre el "nivel" de las tertulias y sus motivaciones. [01:06:12] Referencia rápida a temas de la tertulia anterior: Dataclasses: https://docs.python.org/3/library/dataclasses.html. Se hablo mucho sobre ellas en la tertulia de la semana pasada. Pydantic: https://pypi.org/project/pydantic/. FastAPI: https://pypi.org/project/fastapi/. [01:09:17] Diagnóstico exhaustivo del bug "Memory Leak", causa raíz y propuestas de soluciones. Issue35930: Raising an exception raised in a "future" instance will create reference cycles https://bugs.python.org/issue35930. Exploración del propio código fuente de Python. Repaso detallado del funcionamiento de un "future" https://docs.python.org/3/library/concurrent.futures.html. Uno de los problemas fundamentales de trabajar con hilos es cómo notificar excepciones a otros hilos. La gran ventaja de los "futures" es gestionar esto de forma trivial. Este "transporte" es lo que está ocasionando el "Memory Leak". ¡Agárrate que vienen curvas! [01:21:32] Ojo a la línea self = None. Aquí se rompe el ciclo en la excepción original: https://github.com/python/cpython/blob/3.9/Lib/concurrent/futures/thread.py#L47. Closures: https://es.wikipedia.org/wiki/Clausura_(inform%C3%A1tica). "Pool" de "workers". De forma estándar, Python te proporciona dos ejecutores: el ejecutor de hilos y el ejecutor de procesos https://docs.python.org/3/library/concurrent.futures.html#executor-objects. [01:31:32] Las partes relevantes en el hilo principal son: https://github.com/python/cpython/blob/3.9/Lib/concurrent/futures/_base.py#L413. https://github.com/python/cpython/blob/2fe408497e6838b6fb761e42e8f8ffc70bd6f3b1/Lib/concurrent/futures/_base.py#L387. [01:37:02] ¡Brainstorming! [01:42:42] try ... finally Jejeje, alguien propone algo que funcionaría :-). [01:43:57] Weakref: https://docs.python.org/3/library/weakref.html. Hay contertulios que no están familiarizados con el concepto, Jesús Cea repasa qué son y para qué sirven las "Weakref". Se pueden "resucitar" objetos. [01:51:02] Volvemos al hilo, la corrección del bug. El gráfico de antes, con ciclos: https://lists.es.python.org/pipermail/general/attachments/20201229/0c14bc58/attachment-0002.png. El gráfico de después, sin ciclos: https://lists.es.python.org/pipermail/general/attachments/20201229/0c14bc58/attachment-0003.png. [01:55:12] Comprobar este bug con un test unitario. Por sus características... complicado. "sys.getrefcount()": https://docs.python.org/3/library/sys.html#sys.getrefcount. "sys.exc_info()": https://docs.python.org/3/library/sys.html#sys.exc_info.

In questo episodio affrontiamo l'annoso problema dei memory leak, ossia delle aree di memoria che allochiamo durante l'esecuzione del nostro programma, ma che non rilasciamo nel momento in cui non ci servono più, a causa di errori nel codice o per banale dimenticanza. Come risolvere questo problema in modo efficace? Parleremo di Deleaker, un tool che ci mette a disposizione numerosi strumenti per rilevare ed eliminare questa tipologia di difetti dalle nostre applicazioni Delphi, e molto altro ancora...

The first official episode of The Interns. Listen to Frank and Civan talk about their lives inside their internships. They discuss what happened at work, Frank was sick and that made Civan relive his good old days playing Lord of the Rings Online. Then we discuss new stuff and our very own application which will be in development within the next coming weeks. Disclaimer: We made a small mistake during the convo about the Senate and Facebook. The Senate was in discussion with Google at that point, not Facebook. Show notes: Sean Allen (https://www.youtube.com/watch?v=280mDeWtbn4) & Joshua Fluke (https://www.youtube.com/watch?v=KzT6_o6XfN0)

It's apparently another slow news week in space, as Burt and Yaretta take this week to delve a bit more into Yaretta's past, at least as much as her drug-induced memory loss allows them to. Stories this week include the war between the Birb and the Allamat, and the Vrinrar Holiness Shacren's demand for donations of bread.
Welcome to the first full episode of Cosmic Call! We're so excited to be chosen as the official venue for the release of these shocking broadcasts of a radio show from an extraterrestrial culture! In this first episode, Burt the Printer works to make Yaretta feel more at home, but she seems like she's not adapting well to life on the Tartarus Station. Stories this week include the arrest of Council Member Erurer Nulal, a sports profile on Re-zon player Tarke, a weather update for Dlahmurgan the Living Planet, the heist committed at the Ophyus Art Museum, the Galactic Space Time protests on Bellafoss, and the discovery of the planet Trashoul.

If you are really going to master DevOps you need to master communications. At least the ability to clearly motivate and pull people into the discussion and the goal you are trying to achieve. Spending an extra fifteen or twenty minutes writing an E-Mail can save you days and sometimes weeks of discussions, arguments and apologies. I have a lot of tips about how to be more effective in communicating ideas but today I am going to give you my top six. What is the goal of your communications? A goal is essential to forming any effective communications. If you don't really know what you want to achieve with the message how will anyone else. Some common goals for me when I was an operations lead were getting help with a Memory Leak, let everyone know about upcoming patches to the middle ware, or getting someone to help figure out why a build or deploy is failing. Once you know what the goal is you can easily expand on it and form a complete thought and translate it into a communications. What is your motivation for writing the communications? Sounds weird I know. Communicating why you are trying to solve the problem often goes a long way towards getting people's sympathy or at least an understanding about why you care about the problem. If you try to hide this or omit it you run the risk of pushing people away. That will also draw people in. In those cases where you are trying to help someone else it will also draw them into the communications and compel them to read on. So state it clearly but don't go and on about it. I normally try to keep my motivations locked up in one sentence. To much discussion can come off as bragging, whining, or self-righteousness depending on what is being said. What are you trying to motivate others to do? This one sounds super obvious but it is really more about how you say it then what is being asked or said. This is really the sales pitch part of any communications. I know that for a lot of people this is the most difficult part. We all normally hate being sold things so the idea of selling things to others can be difficult. The thing that really good sales people know is that the best way to sell is not to be a pushy sales person. Instead focus on the benefits of the person you are -selling to- asking for help from. Everyone wants to look good doing what they do best. Making people feel important by asking them for help in areas you aren't the best in is also helpful. A little humility will go a long way towards winning people over to your way of working and thinking. Stay away from certain exclusive words and use more inclusive words. I only speak English so I am not sure if this part holds true in all languages. In English though words like I, me, my, us, Department/Group Names, them and you tend to imply an exclusion of the reader or you as the writer. This exclusion while a minor thing really can put people off and make them restive to your ideas for various reasons. Some people will think you are blaming them, others may think you are dumping work on them, and still others just may not know you so they will use these words as an excuse to ignore you. Instead focus on using words or phrases that imply inclusion like we, our, as a team, etc. Depending on the context these words will have different levels of affect. They will always be positive it's just that some situations are just naturally inclusive so the effect of this is just less visible. Leave the door open to Dialog. Often times the communications I receive are worded as statements of fact and not statements open for discussion. They seem to be written by people who have already decided what the best approach is and they want me to rubber stamp it. It's my job as a Solutions Architect and previously as a Team Lead to resist this. If you are talking about my area of expertise and haven't asked me for input you might even piss me off. So while stating your plan may be acceptable make sure you are always asking for feedback in the communications. This could be a requested meeting, a response to the message, or flat out asking what issues the readers see in what you are presenting or proposing. Like a good beer let it ferment. That's right the best thing to do in most cases is just to let the communications sit for a few hours, overnight, or longer if possible. This is especially good for those times when you are really upset by the actions or lack of actions around a problem. If the communication is an E-Mail save it and go take a walk. I will often write an E-mail, save it as a draft, and then go to lunch. Then when I get back open it up read it I will be fresher and calm. Normally I re-write about half of it to incorporate the other items on this list. Even if I wasn't upset when I wrote it I will normally find places where I can make it better. Let's look at an example. As an example here is a less than optimal communication: "Hey Guys, I really need you guys to look at this memory leak. It's effecting the sites performance and the up time stats. When can your team fix it? Thanks, DevOps Master" Something like this would probably work better: "Hey Guys, We are all really starting to see the effects the slow performance and a growing number of outages that appears to be caused by a memory leak from the look of the stats. Let me know when we can get together today to discuss a strategy to identify the real problem and fix it. Thanks, DevOps Master" The second one pulls the reader in, states the problem I need help with, and asks for a meeting to plan the approach. Remember to always ask for what you want like a meeting today. Expect that your requests are not always realistic and be accepting of those responses offering a different solution or meeting time. Never forget that everyone is busy. The less time everyone spends being irritated with how things are written the more time we all have to fix problems. So make a effort today to write something better. Ask others to proof what you write looking for the things in this article. Look for me to post more tips for improving your communications in future articles.
