Martin Eden, by Jack London

Until recently, all I knew of Jack London is that he wrote White Fang, which I read when I was a child and to my shame sometimes mix up with Romain Gary's White Dog, and To Build a Fire, which is a short story I really liked, but which I mostly use as an example of how cold some places on Earth are. At a friend's recommendation I started reading Martin Eden and I really loved it.

Slowly building the characters and with careful attention to details of action and thought and feeling, London is both heavily autobiographical and feverishly critical of society as a whole. An extreme version of his own history, Martin Eden's character is a street ruffian who had to fend for himself since he was eleven years old. A chance meeting with a beautiful young girl from high society makes him want to be more so he dedicates his life to reading, learning and becoming more like the ideal he believes people in high society embody. Handsome, strong, very smart and blessed with good health and powerful will, he does just that, in short time managing to cross the cultural gap and then continuing to grow and learn until he even becomes a critic of the people he saw as gods just a few years ago.

There is so much more to the book, though. The transformation carries the reader through every strata of society, dissecting behavior, culture and belief, making bold philosophical claims while making one feel and understand from the point of view of this amazing character and others. At the time of the writing, the book was not well received, mostly because of the ending, which I won't spoil here, but how premonitory it was to describe similar events to the actual fate of the book itself! Now it is considered one of the best Jack London books and the one he is more known for.

I've read the Andrew Sinclair introduction after I've finished the book, which is what I really recommend to everyone, since it spoils the entire story. From the intro we learn that the book is heavily based on the author's own life and also of the differences between Eden and London's stories. Sinclair also criticizes some parts of the book, where the writing was not as good or was discordant with the rest of the work, but I personally liked every bit of it. Used to a classical story structure, I always expected some things to happen which did not or happened differently, an early sign that so much of this is based on real life. But also, I feel that having Martin Eden be endowed with so many positive attributes made the book a bit less accessible that it should have been, for the character is a beast of will and life force, of health and capacity of work. London was not as fortunate himself and many a reader will probably feel as I did, that the book hints that only an extraordinary person can break away from their position in life and maybe it isn't worth it anyway. Intended as a critique of individualism and personal ambition, it falls a little flat when we encounter the person London probably dreamed to be.

Bottom line: a powerful book on the nature of life values, as they are taught, believed, chosen and created, about how illusion can spur one to magnificent deeds and hard achievement sour the taste of life itself. It talks of the inner and outer drives of people, making them both majestic and ridiculous. It felt realistic and somehow uplifting and terribly depressing at the same time. I highly recommend it.

How to use a Javascript script in Typescript (Angular 5 CLI)

I am in the process of converting an old web site to Angular 5 CLI. Little technical value other than I need to understand the underlying concepts, but I needed to take some Javascript code and execute it in Typescript, the de facto language for Angular. And you hear that Typescript is a super set of ECMAScript, but it's not as easy to integrate existing code.

So, first of all, we are talking pure Javascript code, not set up as a module or anything more advanced. Let's say something like function say(message) { return 'I say '+message.content+' ('+messsage.author+')'; }. It's a simple function declaration receiving a message object with the fields content and author and returns a string. How to use it in Typescript, which is a strong typed language?

First of all, you need to load the script itself. The file can be added to angular.cli.json, in the scripts section, like this:

"scripts": [
        "../node_modules/jquery/dist/jquery.min.js",
        "assets/js/someJqueryThing.js",...

Next, in the Typescript file you want to execute the code, import the script:

import('someJqueryThing')

(note that it is not some import something from something else syntax, just the name of the script, so that it is bundled in for that page. But at this moment Typescript tells you there is no say method, and that's because you have not declared it for Typescript.

There are two options. One is to add a file called someJqueryThing.d.ts in the same folder with the .js in which you declare the signature of the say function, the other is to declare it in the .ts file you are running the Javascript from. The syntax, for this case, is

declare function say(obj:any):string;

You could declare an interface and specify what kind of object say receives

interface Message {
  content:string,
  author:string
}
declare function say(message:Message):string;

, or you can even declare var say:any;

ASP.Net Core gotcha: Hosting my site in IIS Express, not Kestrel

I did something and suddenly my API was not run in IIS Express anymore, but in Kestrel. I reviewed code changes, configuration changes, all to now avail. I don't want Kestrel, I want IIS Express!!! Why did Visual Studio suddenly decided to switch the development server?

Solution: it is your Visual Studio. The button you use to start debugging has a little dropdown that allows you to choose which server to use. I had probably pressed the wrong one at some point.

My totally unbiased experience with bitter apricot kernels

You will quickly understand why I felt the need to say I was unbiased, but let me first demonstrate how much unbiased I was: I went into this raw fruits store, with an errand from the wife, and wanted to get something from me. Usually I like the caju and macadamia nuts, but I didn't want to have the conversation about why did I spent so much on something I eat out of boredom, so I looked around to get something else. And here they were, packaged and sold just like any other dried fruits or nuts: bitter apricot kernels. So I bought a 200 g bag.

Back in the office, I opened the bag up and I started eating. They were bitter as hell, but I didn't mind it much. I was eating some of them, then switching to candied ginger (which I'd absolutely love if it weren't so sweet), then back again. After a while, though, I'd had enough. About half of the bag in, I couldn't really find a reason to keep eating them. My colleagues had all refused to eat (and spit) more than half of one. But I was curious what they were actually for. People who love bitter tastes, maybe?

So went on the Internet and KABOOOM! mind blown. Just for scale, try to look for yourself at the dimensions of the can of worms I'd just opened: apricot kernels.

Turns out that the "active ingredient" in the apricot kernels is amygdalin, a substance that turns to cyanide in the gut. Yes, you've heard that right: I had just bitten the tooth, dying for the motherland before I could spill the beans. Google had already failed miserably, by serving first a page that explained how Big Pharma and governments conspired to keep this wonder drug from the public. The second page was Wikipedia, then every single conspiracy nut site, sprinkled with the occasional very dry scientific study that bottom lined at "we don't really know".

But I am getting ahead of myself. At this point I was already severely biased and I first need to describe my earnest experience to you. Short story: accelerated heartbeat, fever, terrible headache and nausea that lasted for half a day. Also, didn't die, which was good.

Back to my rant. So, some guy looked at the chemical structure of amygdalin and thought it looked like a B complex vitamin, so he named it vitamin B17. It was quickly marketed as a cure for cancer, despite numerous trials to show that it wasn't. And no, it's not a vitamin for humans either. It is not made in the human body, but it's not needed, either. The bag was not labeled anything dangerous, because it came from the outside of the European Union, which has a law regarding this. Here is some advice for both the EU and the US. Turkey was OK, though, so it only said "great for cancer, eat 5 to 8 seeds daily, not all at once".

So how fucked was I after eating about one hundred of them? A European Food Safety Authority article said that eating three kernels exceeds the safe level for adults. A toddler could do that from just eating one. An article from Cancer Council Australia detailed the child fatalities due to ingesting apricot seeds. Another article was telling me of an adult who got poisoning, but he was both stupid and extreme (he was taking a concentrated extract) and didn't die anyway. A thousand other sites were telling me how amazing my health will be after I had just eaten ten times the daily dosage they suggested.

Drowned in the sea of controversy regarding apricot kernels I've decided to look for the chemical and medicinal treatment for cyanide poisoning. Step 1: decontamination. It was kind of too late to go to the toilet and do the anorexia thing. Step 2: take some amyl nitrite (and then some intravenous things). Wait, that's a party drug. I could maybe get one in a sex shop. There was no home remedy and most of all, even if the amyl nitrite seems to work, no one seems to know exactly why other than the vasodilating effect it obviously has. Another possible antidote is (ironically) hydroxocobalamin, also called vitamin B12a. In the end some vitamin C and a headache pill did wonders, just in case you eat a bunch of apricot kernels and feel awful. Obviously, if it were a serious condition I would have died at the keyboard, trying to wade through the marketing posts and the uselessly dry official reports. Also, not enough easily available party drugs, I dare say.

So, days later the bout of shaky hands, fever and the horrible headache that only blood oxygen deprivation can bring, I decided to write this post. I doubt people will find it with Google, but maybe just my immediate friends will know not to eat this crap.

Stargate Origins - a horrible beginning

A pilot for the much awaited Stargate Origins series was released. My prognosis: it will be a disgusting flop, yet remember that Stargate SG-1 was kind of terrible in the beginning and it went very far in the end. Since SG-1 and Atlantis went really over the top, the only solution was a prequel, but considering the Stargate universe, I bet it will be very difficult to reconcile any prequel with the events in the existing series.

First of all, there is the distribution format: it's a web series. Instead of a pilot episode lasting 45 to 60 minutes, they released three episodes, 10 minutes each. The "webisode" format doesn't give me a lot of hope. However, this might be a marketing ploy, to check how many people are actually still interested in the franchise. If they see they have a big fan base, they can always improve the show or start a serious one.

But now comes the real bummer: the quality of the show, from the productions values to script and acting, is abysmal.

They went with the gender swap crap: female protagonist, female director, etc. Yet instead of a character we can sympathize with or want to be her, we get an abusive, annoying and very stupid person who, if they were male, would have been pathetic and offensive. As female, it grates the nerves. See the scene where, tied up, surrounded by Nazis with guns who have her father hostage, she spits, bites and says "you're a dead man" and "next time I'll really make you bleed" to a Nazi officer. It does feel like the role was written for an adolescent, maybe prepubescent boy, then it was changed just a little for a 19 year old woman.

Which brings me to the next point: the Nazis. The Nazis again, portrayed as they always are: ugly, mean, pompous, fanatical, always mentioning their Führer, stupid, narrow minded, etc. How can you do any good writing with cardboard characters? The answer: you can't. Start a show like this and you miss out the opportunity to see the Americans, British and Nazi Germans cooperate against the teachings of their respective cultures in order to defeat the Goa'uld threat. I have high hopes for the camerawoman, who in all this disaster seems to have escaped with good characterization and a decent actress.

Last, but not least, the production values would have been bad in a student project. Almost no post processing, the special effects are horrid, the soundtrack is slapstick from other series and there are some moments (an alien landscape seen through a window which is an obvious pastel drawing, for example) that make you wonder which 10 year old genius made that for a school project.

So you have a cheap production that a few fans in a basement would have done better, marred by bad setup, unusable characters and stupid writing. All of these can change: money can be spent, writers and directors changed or motivated, step taken to improve something that fans have been waiting for for a long time. However, what cannot be changed are the actors. The lead actress is bad, as are the two "young good guys". There is no getting around that. The others are not much better. Even Connor Trinneer, who you might remember as Trip, the engineer in the Star Trek: Enterprise series (and was also in a few episodes of SG Atlantis) and in this plays "the father", acted dazed and confused, as if asking "how did I get here? what am I doing?" in every scene. He was probably regretting taking the role. And he is 48 years old, he could have played the dad without the cheap white hair and mustache.

Bottom line: Trying to YoungIndianaJonesize Stargate was always a tough sell. Doing it with such lack of respect for the franchise and to the cinematic art is mind boggling. Didn't they want to succeed with this? I am baffled. Here is the trailer.

Annihilation (Southern Reach #1), by Jeff VanderMeer

Annihilation, by Jeff Vandermeer, is a very short book that seems to be inspired by the Strugatsky brothers' Roadside Picnic. The same timeless quality, thoughtful introspective characters and a weird area that seems to defy the laws of physics and biology. But nothing is truly revealed, or learned, other than the somewhat senseless thoughts that the main character has. The other three women quickly succumb to the influence of "Area X", so we are left with a weird chick moving around in an unexplainable place with unfathomable rules. If Dallas' Pamela would have woken up from a dream at the end of the book, it would have meant just about the same as the actual ending.

I only read the book because of the upcoming movie. I am fairly certain that it will be better than the book, which manages to bore in half the pages of a decent story. It isn't that I disliked it, it's that I did not actually like anything in it. Everybody is acting crazy and without context and in the few pages that bring some context, it's the boring relationship between the lead and her husband and I couldn't care about any of them.

I am sorry, but when you write a book about a scientific expedition, it's customary you write about characters that behave like scientists, not like directionless drunkards with self-traumatic histories. I don't understand how this book won any science fiction award. It is well written, but it's barely average. I am not going to read any of the other books in the trilogy.

ASP.Net Core "System.InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found."

Update for .NET Core 3.0:

Seems for .NET Core 3.0 the solution is much simpler:

• install the Microsoft.AspNetCore.Authentication.Negotiate NuGet package
• add authentication in ConfigureServices like this:

  services
      .AddAuthentication(NegotiateDefaults.AuthenticationScheme)
      .AddNegotiate();

• use the authentication in Configure (above app.UseAuthorization();)

  app.UseAuthentication();

No need to UseIISIntegration, UseHttpSys or anything.

Original post:

If you get the System.InvalidOperationException "No authenticationScheme was specified, and there was no DefaultChallengeScheme found." it means that ... err... you don't have a default authentication scheme. Solution:

• Install NuGet package Microsoft.AspNetCore.Authentication in your project
• add

  services.AddAuthentication(Microsoft.AspNetCore.Server.IISIntegration.IISDefaults.AuthenticationScheme);

  to the ConfigureServices method.

Update: Note that this is for IIS integration. If you want to use self hosted or Kestrel in debug, you should use HttpSysDefaults.AuthenticationScheme. Funny though, it's the same string value for both constants: "Windows".

Oh, and if you enter the credentials badly when prompted and you can't reenter them, try to restart Chrome (as in this answer)
