What's Expected of Us and Others is a collection of stories by Ted Chiang including
  • Exhalation
  • Dacey's Patent Automatic Nanny
  • The Truth of Fact, the Truth of Feeling
  • The Lifecycle of Software Objects
  • What's Expected of Us
  • The Merchant and the Alchemist's Gate
  • The Great Silence

All the stories are speculative fiction, their subjects related to the meaning of life and evolution in relation to technology. His writing style is direct, unsophisticated, often based on first person perspective and dialogue. It's the ideas that he is exploring where he spends most of his efforts. All in all a nice collection of sci-fi, but not something extraordinary in nature.

Sometimes we need to execute an async method synchronously. And before you bristle up and try to deny it think of the following scenarios:
  • event handlers are by default synchronous
  • third party software might require you to implement a synchronous method (like a lot of Microsoft code, like Windows services)

All I want is to take public async Task ExecuteStuff(param1) and run it with ExecuteSynchronously(ExecuteStuff, param1).

"What's the problem?", you might ask, "Just use SomeMethod().Result instead of await SomeMethod()". Well, it doesn't work because of the dreaded deadlock (a dreadlock). Here is an excerpt of the .Net C# code for Task<T>.InternalWait (used by Result and Wait):
// Alert a listening debugger that we can't make forward progress unless it slips threads.
// We call NOCTD for two reasons:
// 1. If the task runs on another thread, then we'll be blocked here indefinitely.
// 2. If the task runs inline but takes some time to complete, it will suffer ThreadAbort with possible state corruption,
// and it is best to prevent this unless the user explicitly asks to view the value with thread-slipping enabled.
Debugger.NotifyOfCrossThreadDependency();
As you can see, it only warns the debugger, it doesn't crash it just freezes. And this is just in case it catches the problem at all.

What about other options? Task has a method called RunSynchronously, it should work, right? What about Task<T>.GetAwaiter().GetResult() ? What about .ConfigureAwait(false)? In my experience all of these caused deadlocks.

Now, I am giving you two options, one that I tried and works and one that I found on a Microsoft forum. I don't have the time and brain power to understand how this all works behind the scenes, so I am asking for assistance in telling me why this works and other things do not.

First of all, two sets of extensions methods I use to execute synchronously an async method or func:
/// <summary>
/// Execute an async function synchronously
/// </summary>
public static TResult ExecuteSynchronously<TResult>(this Func<Task<TResult>> asyncMethod)
{
TResult result = default(TResult);
Task.Run(async () => result = await asyncMethod()).Wait();
return result;
}
 
/// <summary>
/// Execute an async function synchronously
/// </summary>
public static TResult ExecuteSynchronously<TResult, TParam1>(this Func<TParam1, Task<TResult>> asyncMethod, TParam1 t1)
{
TResult result = default(TResult);
Task.Run(async () => result = await asyncMethod(t1)).Wait();
return result;
}
 
/// <summary>
/// Execute an async function synchronously
/// </summary>
public static void ExecuteSynchronously(this Func<Task> asyncMethod)
{
Task.Run(async () => await asyncMethod()).Wait();
}
 
/// <summary>
/// Execute an async function synchronously
/// </summary>
public static void ExecuteSynchronously<TParam1>(this Func<TParam1,Task> asyncMethod, TParam1 t1)
{
Task.Run(async () => await asyncMethod(t1)).Wait();
}

I know, the ones returning a result would probably be better as return Task.Run(...).Result or even Task.Run(...).GetAwaiter().GetResult(), but I didn't want to take any chances. Because of how the compiler works, you can't really use them as extension methods like SomeMethod.ExecuteSynchronously(param1) unless SomeMethod is a variable defined as Func<TParam1, TResult>. Instead you must use them like a normal static method: MethodExtensions.ExecuteSynchronously(SomeMethod, param1).

Second is the solution for this proposed by slang25 :

public static T ExecuteSynchronously<T>(Func<Task<T>> taskFunc)
{
var capturedContext = SynchronizationContext.Current;
try {
SynchronizationContext.SetSynchronizationContext(null);
return taskFunc.Invoke().GetAwaiter().GetResult();
}
finally {
SynchronizationContext.SetSynchronizationContext(capturedContext);
}
}

I haven't tried this, so I can only say that it looks OK.

A third options, I am told, works by configuring every await to run with ConfigureAwait(false). There is a NuGet package that does this for you. Again, untried.

It is said that the great theory of relativity of Einstein's doesn't apply to things moving slowly. Today I realized that is not true. There is a direct relationship between space and time and speed affects space, so it must affect time. Here is a practical example: a car moves faster than a person walking, so its speed makes distance shrink relative to time. Inversely, that means that it makes time expand, become more expensive, from the car's point of view.

That is why, when you see a car approaching and you have the option of walking in front of it forcing it to stop, you wait, because the driver's time is more expensive than yours. Stopping the car and wasting time would impact him much more than it would you. It also has the side effect that it saves your life if the car doesn't stop for some reason.

Just a thought.

The Romanian language has a word: deștept. It means smart, but it leans into knowledgeable, so it means both "knowing things" and "thinking fast". There is no relation to wisdom and this is the case in other languages as well. Sometimes wise is used to denote knowledgeable, yet I don't think they are related. While to know things means to be able to recall things you have learned, wisdom, I've come to realize, means to understand what little you know. Someone might be wise and know very little and think rather slowly. Wisdom is the maturation of the soul, like a well kept wine it provides subtle flavors.

Even a superficial and forgetful person as myself can gain wisdom in time. It is important to note this, because as people get older, stuck between that limit of usefulness and the onset of senility, we tend to dismiss them, flaunt our new found (and invented) knowledge to their faces, ignoring a very important aspect of their evolution: wisdom. Sure, their wisdom might not apply to your field or need, but even if it were, are you acknowledging it?

Just a thought.

As far as I can see, Ted Chiang's Tower of Babylon is the first thing he published. It's a short story (that you can find online for free) about two workers climbing the tower of Babylon to dig through the Vault of Heaven.

In this story the tower is not struck down and the people have been working on the tower for centuries. It's a fun read, although not particularly funny or captivating. It does show Chiang's penchant for speculative fiction, though. I liked it, but not enough for four stars and three seems too little. Read it. It's short and I don't want to write more about it than it is itself in length :)

I am writing this post to let people know why a particular annoying problem happens on Windows 10 with regards to notifications. Before it was called "Focus Assist" it was called "Quiet hours" and you would turn it on to make annoying notifications not show while you were working or playing. After a Windows update, Microsoft renamed it to Focus Assist and turned it into a more complex setting, rather than on/off. But then the problems appeared.

Symptoms:
  • Notification traybar bubble is white (outline filled) and going over with the mouse it either says nothing or says "1 notification"
  • When you click on it, it shows no notifications and the bubble remains filled
  • If you right-click it, none of the options in the Focus Assist menu seem to be working and none are checked
  • If you go to Settings and click on Focus Assist, Settings crashes with no error message
  • You also may have Avast antivirus installed

People have been tracking the problem on this Microsoft forum: Settings app crashes accessing "Focus Assist" settings and here are our findings:

  1. The problem comes from Avast (or some other source) turning off the Windows Push Notifications User Service. Turning it on, restores Focus Assist functionality.
  2. Avast has something called Silent Mode, which many people use because Avast started pushing all these annoying messages lately
  3. In the Avast configuration (go to Menu , Settings, Components, scroll down the page until Performance, Do Not Disturb Mode, then Customize) there is a setting called "Silence notifications from 3rd-party apps". By default it's on. Turn it off and Avast will no longer kill the service
  4. If the cause of this behavior is different from Avast's silent mode, let me know. An immediate fix is to go to Services (services.msc), scroll down to Windows Push Notifications User Service (followed by underscore and some meaningless numbers and letters) and make sure it is started.


Hope this helps.

A Conjuring of Light ends the Shades of Magic trilogy, although apparently a new trilogy set in the same universe is on its way. All the major threads are closed, although some of them felt a little forced and some of the drama was clearly artificial. But at least it all ends, which is one of the major reasons I read this book, only to see how Victoria Schwab's characters will end up.

I felt that this was the more ambitious volume of the three in the series, with all three Antari having to interact, with foreign dignitaries stuck in the royal palace while it was under siege from a demented magical creature who believed itself a god, with ties with families and past revealed, with new places and new magic. However, the book was quite inconsistent. For example, there is a plan to use a spell to seal the god in a body. When it is inside one, they forget about it and fight him with knives and fire and what not. There is a spell that could restore Kell's memory. He wonders if he should use it, then we forget about it. As for Grey London (ours) and Black London (the one where the creature originated), they are completely ignored.

The personalities of the characters also change a lot, with everyone acting brave and selfless (sometimes to stupidity) as if forgetting we are talking about a ruthless street thief, a killer turned sociopath by years of torture and so on. To me it seemed as if the author wanted a tough story, but she couldn't help turning it into a classic hero quest with a happy ending.

Bottom line: I had fun reading the series, but I won't continue with the next trilogy. It's not bad, but it's not above average either.

Kind of obvious, but I wanted to make it clear and to remember it for the future. You want to make something appear or not based on a toggle button, usually done by adding a click handler on an element with some code to determine what happens. But you can do it with HTML and CSS only by using the label element pointing to a hidden checkbox with its for attribute. Example:

   I have been toggled!

Here is the HTML and CSS for it:
<style>
/* you have to use a caption element instead of a control element inside the label, so a button would not work and we use a span to look like a button */
.button {
border: solid 1px gray;
padding: 5px;
display: inline-block;
user-select: none;
cursor: pointer;
}
 
/* the element after the unchecked checkbox is visible or not based on the status of the checkbox */
#chkState + span { display: none; }
#chkState:checked + span { display: inline-block; }
</style>
<label for="chkState">
<span class="button">Toggle me!</span>
</label>
&nbsp;&nbsp;&nbsp;
<input type="checkbox" style="display:none" id="chkState" />
<span>I have been toggled!</span>

Update: You might want to use an anchor instead of a span, as browsers and special software will interpret it as a clickable, but not input control.

Update: You can, in fact, instruct the browser to ignore click events on a button by styling it with pointer-events: none;, however that doesn't stop keyboard events, so one could navigate to the button using keys and press Space or Enter and it wouldn't work. Similarly one could try to add an overlay over the button and it still wouldn't work for the same reason, but that's already besides the point. Anyway, either of these solutions would disable the visual style of the clicked button and web sites usually do not use the default button style anyway.

There is one reason why you should not use this, though, and that is usability. I don't know enough about it, though. In theory, a label should be interpreted the same as the checkbox by software for people with disabilities.

There is this channel I am subscribed to, with various people discussing or demonstrating software development concepts, with various degrees of success. I want to tell you about this series called CSS3 in 30 Days which is very well organized and presented by a clearly talking and articulate developer, Brad Hussey. He's nice, he's Canadian.

And before you go all "I am a software programmer, not a web designer", try watching it for a bit. Personally I am sure I would have solved a lot of what he demos using Javascript. Changing your perspective is a good thing. Note it is about CSS3, which had quite a few improvements over the classical CSS you may know already.

Here is the first "day" of the tutorial:

Paranoia Agent (or Delusion Agent, maybe) is an anime by famous anime director Satoshi Kon, unfortunately killed by cancer in 2010. His work is always more than it seems, focusing on the inner worlds of people and how they all perceive things differently.

The anime is only 13 episodes and starts with a simple case of violent assault on the street and then becomes stranger and stranger until it is not clear which is real and which is in someone's head. It critiques the repressive Japanese society and human nature in general, it goes from police procedural to slapstick comedy, from horror to psychological drama. The ending is, as they say, a mystery that doesn't stay solved for long. I quite liked the anime and I recommend it highly. It is rarer and rarer to find Japanese anime which is not derivative or simply idiotic.

It involves Russia! The story of how Boris Pasternak's Doctor Zhivago got popularized and received the Nobel prize for literature is fascinating and one of the reasons why my wife and I decided to read it as part of our own private book club. She loved the book, although she admitted she didn't understand a lot. I couldn't finish it because I didn't understand it at all!

Let me get this straight, this is not a bad book, the fault lies solely with me. That being said, I've read half of it before I decided to watch the TV adaptation from 2002 and realized I had no idea who anyone was. I had read half of a book, enjoying the way Pasternak describes individual lives, but I didn't remember one character or scene. And the explanation is simple: this is like Crash, on steroids, had sex with Gone With The Wind and had this bastard child around the first World War in Russia. People have three different names, plus nicknames, that the author just splays around without explanation. Events are described through short chapters that sometimes connect via a character seeing the same things from a different perspective or saying something about a character, using a different name than the one we read about it previously. And all these people keep bumping into each other again and again. Sometimes there is no rhythm in how things are written, sometimes it sounds like poetry. There is huge attention to some details and complete ignoring of others. And so on. It is not an easy book; it requires your full attention.

It is obvious that Pasternak loved people and he described their experiences and toils during times of great upheaval, but for him those paled compared with the love stories and the feelings of the characters involved. I can understand how he was confused on why people thought his book was against the Soviet system, where it was clearly about people. I am sure this book is great, it is just not for me. If you want to try it, I suggest you read the summary in Wikipedia so you understand what is going on and you do not read it in bits of 15 minutes in the subway.

I started watching Killing Eve, the BBC TV series starring Sandra Oh and Jodie Comer, and I quite liked it. So I've decided to read the books it is based on, Codename Villanelle being the first one. The result is a mixed bag. I clearly prefer the TV show, but the book is not bad either. They are, I have to say, quite different.

While both focus on a police woman trying to find a highly skilled female professional sociopath assassin, the show adds a little dark humor, which is both nice and off putting, while the book is going for the full "secret world of spies and weapon technobabble" route, which is also half and half. I think Luke Jennings wanted to write a simple spy story, inspired by the likes of John le Carré, while the show screenwriters have more ambitious goals. Most of the little episodes there are based on stuff in the book, but wholly reinterpreted, the characters changed or added, their fates changed.

But enough about TV. The book is easy to read, but a bit one sided: kill after kill and the chase of the department that has to uncover not only the identity of the killer, but also who are the high placed people who help hide her tracks, without most of the emotional exposition that makes a character relatable. Funny enough, there is more emotional content related to the killer than the cop. Makes you wonder which one of them is the psycho sometimes.

In conclusion, I will not read the rest of the books, but I will continue to watch the TV show. I feel like reading the first book opened my eyes on what the characters were supposed to be and thus Codename Villanelle acted like a nice companion book for an interesting series that I enjoy watching.

I liked Binti, even it is a short story. It is my first contact with the Nigerian-American author Nnedi Okorafor and I loved how African ideas blended with science fiction concepts in Binti. I will probably read the others in the trilogy, sooner or later.

The story is about a girl that leaves her tribe and planet to go to a university she was just admitted to. Just when getting there, an alien race of Medusae kills everybody except her. You will have to read why that happens and how she becomes the ambassador of the aliens, because the story is short enough to get spoiled by a detailed review. The writing is not without flaws and the character is dangerously close to the one in Who Fears Death, but I felt that it made a lot more sense in the context of an interstellar Federation as in Binti.

Read it. It was fun.

Who Fears Death is an interesting book mainly because of the Nigerian background of Nnedi Okorafor, the author, and the subject vaguely inspired by the atrocities in Sudan. The fantasy plot revolves around a girl resulted from intertribal rape who has to deal with the injustices of her world using her magical powers. Imagine a Harry Potter book in a German extermination camp scenario where he is a Jewish girl and you get close. In fact, this and other books on the subject of tribal hatred in Africa should make any white supremacist feel good about themselves, because there is no worse racism than between violent religious uneducated tribes that pretty much look the same.

Yet the book's interesting factor kind of stops there. The African culture references throughout the story keeps it entertaining, but the plot is a classic hero arc with pretty much all of the flaws inherent to the genre. Hero is young and powerless, discovers powers, is guided by mentors that keep from her just about everything there is to know and use up until she needs it, evil villain to whom she has a direct connection and opposition, friends that are there just to support the hero, things that happen for no other reason than they needed to further the story in a particular direction, she has amazing powers but uses them sparingly and often is stopped from using them for moral reasons by her friends and so on. In fact, it gets a lot worse, considering the hero is an African girl who could get killed at any moment by an angry mob just for the color of her skin, moving around in a society where even her boyfriend thinks it's OK to keep things for himself or treat her patronizingly just because of her gender, not to mention the old male mentors.

So while the book is interesting and well written, it does have a major flaw in the way it was structured as a story. Perhaps the docile Black woman who occasionally gets upset and then regrets it resonates better with African audiences, but for a Westerner it might get a little frustrating. It is a book worth reading, mainly because of the culture shock one experiences while reading it, but it could have been better.

Who writes like this in this day and age? Around 10% in the book I was convinced The Great Influenza was written sometime in the middle of last century, when people still did painstaking research and paid attention to every detail, not like now, when researching something involves trying different Google keyword combinations ad nauseam. And how many people can pack so much information and knowledge into a book that is also easy to read and incredibly captivating? Apparently, John M. Barry, with this book published in 2004.

I can't stress enough how much I liked this book. I would give it 6 stars out of 5 just because I rated books with 5 stars and this is an order of magnitude better. Imagine that I only found it because I was curious about the influenza epidemic from 1918, what is popularly known as The Spanish Flu, and at the time I was worried that one book on the subject would clearly not be enough. Not only would it present just one point of view, but surely various interests or lack of resources would influence (pun not intended) the end result. Instead I was shamed, that is the right word, by the amount of care the author used to research and write this book.

In order to explain what the book is about I would have to write a lot about The Spanish Flu, a disease that killed between 50 and 100 million people globally within six months in the middle of a five year world war that killed just 20 million in military and civilian deaths combined. Yet very few people care about it or even know about it. There are few documents about it, no movie that I know of, very few books. Inside the pages of The Great Influenza are the seeds of a dozen Steven Spielberg war movies, various crossings of The Outbreak with The Knick and a few Netflix series - I find it criminal that no one thought about it so far. Therefore, I urge you to first read a little about the disease itself, on Wikipedia and Google like normal people, then read this book. It will blow you away.

John Barry is clearly an investigator at heart. Not only does the work for this book, but clearly empathizes with the people who fought to understand disease and find cures, locked in laboratories and sacrificing everything for understanding. He calls them The Warriors, the name of the first part of the book, where he describes the history of medical science in the Unites States and the people how would ultimately champion it further and fight the outbreak. The second part (out of ten) describes the disease: a type of influenza so virulent that it makes the immune system destroy the body it's supposed to protect. Only from the third chapter on we start reading about how the pandemic started, what influenced its movements, how people reacted and so on. The last two chapters are solely about the after effects (almost as important as the ones during the pandemic). A whopping 10% of the book is just notes and thanks and references.

Also relevant, I think, is the fact that Barry is American and clearly proud of it. The book has a very American centric view, not only because of the nationality of the author, as probably because it would have been a lot more difficult to research the actual events in other parts of the world. Yet even for an American patriot the book is filled with outrage at the way governments and local authorities and narrow minded bureaucrats treated the disease and the people affected by it. For an European as I am, the way a fanatical American president managed to turn an entire country into a weapon, effectively disabling the values that Americans are known for: democracy, freedom of speech, pursuit of happiness, etc, is beyond chilling. America was a sleeping giant way before Pearl Harbor and the way it awakens and consumes everything and everyone that stands in its way is ironically similar to the way the influenza virus swept the world. One of the main reasons people don't know about the disease is because any mention of it that could have affected morale during times of war was censored in the land of the free. The name Spanish Flu itself comes from the fact Spain was not censoring its media at the time.

Bottom line is that I urge everyone to read this book. It's a wonderful example of how one man can dedicate seven years to research and document something as scary, monumental and mysterious such as the great influenza pandemic of 1918, analyse it from multiple viewpoints, name, quote and praise the people who were right in the midst of battle, the unsung scientist heroes of unheard of laboratories and the people who gave them the wind under their wings. Great job, John Barry, great job indeed!
