I was trying to do a simple thing: configure a daily rolling log for log4net, meaning that I wanted that log files would be created daily and the name of the files would contain the date. The log was already configured and working with a normal FileAppender, so all I had to do was find the correct configuration. There are several answers on the Internet regarding this. I immediately went to the trusty StackOverflow and read the first answers, copy pasted lazily, and it seemed to work. But it did not. So warning, the first answer on StackOverflow about this is wrong.

So, my logs had to be named something like Application_20150420.log. That means several things:

• The name of the appender class has to be set to log4net.Appender.RollingFileAppender
• The name of the log files need to start with Application_ and end in .log
• The name of the log files need to contain the date in the correct format
• The logger needs to know that the files need to be created daily

This is the working configuration:

<appender name="FileAppender" type="log4net.Appender.RollingFileAppender">
     <filter type="log4net.Filter.LevelRangeFilter">
         <acceptOnMatch value="true" />
         <levelMin value="DEBUG" />
     </filter>

  <file type="log4net.Util.PatternString" value="c:\logfiles\Application_.log" />
  <appendToFile value="true" />
  <rollingStyle value="Date" />
  <datePattern value="yyyyMMdd" />
  <preserveLogFileNameExtension value="true"/>
  <staticLogFileName value="false" />

  <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %-5level %logger - %message%newline"/>
  </layout>
</appender>

As you can see, it is a little counter-intuitive. You do not need to specify the date in the file name, it will be added automatically, and you absolutely need to use preserveLogFileNameExtension, otherwise your files would look like Application_.log20140420

I took the name of the anime from a YouTube video, recommending it as one with a great twist in it. I watched for two episodes as the main protagonist, an ordinary guy in a Japanese highschool, starts talking to a strange girl (Haruhi Suzumiya) in his class, gets coopted in a mad scheme to create a club that investigates mysteries - specifically aliens, time travelers or espers, then adding the three other members of the club. I thought it was going to be about this club actually investigating something. But no, in the third episode we realize that the three other members are an alien, a time traveler and an esper. Soon after we find out that they know about each other and that each of them and, indeed, their entire race/organization were figments of Haruhi's imagination made reality. Haruhi apparently has the ability to create entire universes, essentially making her a goddess, albeit unknowingly.

So far so good, but then for 28 episodes I waited for anything interesting to happen. Where was that amazing twist? Apparently, the twist was that she was some supernatural phenomenon and that's it. The rest is just a typical cliched Japanese high-school story, the one where the lead character is a male boy surrounded by beautiful girls that have an almost undisclosed interest in him and that do crazy stuff together. When the last episode wasn't even closing the series, I got really mad. It was a complete waste of my time. Ugh!

A World Out of Time is a book out of time as well. Larry Niven wrote the book in 1976 and it describes events that happen over a span of three million years, but it feels like The Time Machine. The hero is a guy from the 70s who's memory gets uploaded in the body of a convict hundreds years later, sent on a mission that was supposed to last tens of thousand of years (Earth time), but ending up in a joyride around the galaxy that brings him back on Earth millions of years later. The strange world of immortal creatures living like feudal savages in a world filled with broken and discarded technological wonder, but somehow still looking human, is difficult to take in. The cowboyish behaviour of the lead character and his inconsistent switch between genius and ineptitude don't help either.

It doesn't mean the book is not entertaining. I had fun with it. However it feels really long and old and I don't intend to read the other two Niven books in the same batch: The Integral Trees and The Smoke Ring, even if they sound slightly more interesting.

The second book of The Reckoners series revolves around Firefight, a character from Steelheart, the first book, that I cannot explain without spoiling it. Brandon Sanderson outdid himself, managing to describe a dark world of bright colors, a desperate and dramatic situation in which hope shines through, an impossible romance inside a war story and a totally positive view on fear. Contrasts everywhere, like a bad metaphor that discovers it is a simile before a book ends. Well, if you read Firefight you will get the reference.

The action and plot of the book are much more detailed and a level above what happened in Steelheart. The villain is more interesting, the interactions between the members of the team are more complex, with various shades of conflict, plus an interesting new location in a sunken city filled with glowing plants that feed the people and provide light at the same time. I can't wait for Calamity, the third book in the series, to appear in 2016.

I am starting to like Brandon Sanderson. Only at the end of Steelheart did I realize that he kind of used the same plot device that he used for Elantris: the ten-years-ago one. Ten years before the action of the book, Calamity struck: a red star-like light in the sky that gave random people immense powers. The governments of the world tried to fight back, but all of them ended up capitulating, declaring "epics" as impossible to control as natural disasters. Enter David (the name probably not chosen at random) an eight year old child who witnesses the death of his father at the hands of an epic that then proceeds on taking over Chicago as his personal fiefdom. Now, at 18, David meets with The Reckoners - a group dedicated to fight back - in order to avenge his father.

First book in The Reckoners series, which is a planned trilogy, Steelheart is a very refreshing take on the superhero genre, original in the sense that it takes its name after the main villain and follows a young boy who advances in life using his cunning, knowledge and personal effort, not some random superpower. The characters are easy to sympathize with and the story is very nice. Not everything is perfect, as the story contains many political, economic and even technical plotholes. However, the writing is very well done, easily making the reader forget and forgive any inconsistencies between reality and the storyline.

As with Elantris, I listened to the audio version of the book. Classical narration, but was very nice. The book is a sort of young adult thing, but I enjoyed it very much nonetheless. I can't wait for the second book in the series: Firefight. I may have to first read Mitosis, a short story placed in the same universe.

In a world dominated by trilogies and quadrilogies and sagas, it is refreshing to see that some people are writing stand-alone fantasy books. I've first heard of Brandon Sanderson when he ended up writing the last books in the Wheel of Time series, after its initial author died; those books were the best in the series, even if he had to work with Jordan's notes. Recently, I've stumbled upon this audio adaptation of Sanderson's book Elantris, produced by Graphic Audio, a company that doesn't just created narrations of books, but full audio plays - while changing nothing of the initial text.

Despite some parts being a bit too optimistic, some too slow and some really obvious - waiting for a character to catch up with you is not fun - the book was really entertaining and original. It also was Sanderson's first widely released book, so I can forgive his lack of perfection :). I really liked the story and the characters in the book. In truth, the book's message is one of hope, one of encouragement toward the human spirit becoming the best it can be. I couldn't help thinking that Sanderson probably portrayed himself in Raoden, and that guy is great.

Anyway, the plot revolves around the magical city of Elantris, populated by God like creatures that shine with the light of magic and are almost omnipotent. However, the story starts ten years after a horrible collapse of said city, which transformed every Elantrian into an immortal husk, heart not beating, hair falling, skin blotched by dark spots, incapable of healing the smallest cut or bruise, but fully capable of pain, unneeding of food, but fully able to feel ravenous hunger at all times. The process, called Shaod, has not ended, it still occasionally picks people at random and turns them into these creatures of eternal pain. The human inhabitants of nearby towns have quarantined Elantris and anyone affected by the Shaod is thrown inside the rotting city.

There are two main characters: prince Raoden and his bride to be, princess of a nearby kingdom, called Sarene. Not only them, but almost every actor is full of spirit (pun intended) and really likable, even the antagonists can be understood and sympathized with. The story is full of events that lead to character development, politics, smart plotting, drama and comedy.

Well, in the end, with all my talk of stand alone books, I was a bit sad to see the story end. I wanted more, and that's a good sign, right? Sanderson is supposedly considering writing a sequel, but it's not something that will happen soon and it will involve different characters. I liked Elantris and I recommend it to all fantasy fans.

There would be no point for reviewing the individual books, since, like with Corwin, it is one big story spanning five books. Eight years after the first five disappointing books in the series were published, Roger Zelazny comes back with a little more writing skill, a more interesting plot and a different character. That's the good news. The bad news is that it is pretty much like the Corwin cycle, only with a guy that uses magic instead of a stupid sword. His name is Merlin and he is Corwin's and Dara's son, inheriting both Amber and Chaotic blood. Somehow he still gets his ass kicked by his father, though.

The characters are again, like something from a high school teen movie set in the middle ages. People are mortal enemies and then make conversation, make up and help each other against another mortal enemy, who will probably help them both sometimes later. Arrogant nobility behavior mixes with a general ineptitude to use any knowledge from the "shadow lands" even if a lot of the characters gain their education on Earth. The only interesting thing seems to be an AI that Merlin created... which then calls him dad and acts just like every other generic character in the books. And everybody is just so amazingly and mind stunningly stupid! I couldn't take another book in this crappy series.

Bottom line: The Amber Chronicles was a total waste of my time, the only advantage it has being that its writer ended both cycles and then died, making any sequels improbable. I kid you not, Eragon was way better and it was written by a 19 year old!

And thus ends the fifth book in the Chronicles of Amber, and the last in the Corwin cycle. Written between 1970 and 1978 by Roger Zelazny, it was one of the most lazy fantasy series I've read so far. The Courts of Chaos is once again a book that has no connection with its title. Nothing really happens in the courts of chaos except at the very end. All previous developments in the story are discarded completely and it feels like the author slept through writing the book. It was one of the most WTF books in the series so far, as well. At every section there was at least one scene where I felt like those people watching football games and shouting at their TV about what the player should have done.

Let me give you some examples. The book itself starts with a circular time paradox, where we get to see Corwin cut off Benedict's artificial arm. This had already happened in the previous book, but from the other perspective. Thus the metallic arm was only there to be severed because it has been severed in the past, its origins non existent. Then each of the children are given orders by their father. Why would they listen to them is beyond me, as was his entire reason for leaving, reappearing, etc. Anyway, he sends Corwin on a quest to carry the Jewel of Judgement (nobody did any judgement with that stone!!) to the courts of chaos, where Benedict already went using a trump card. Of course, why call Corwin's grandfather to make another card so that he can get there instantaneously? Why indeed. So we are exposed to this totally boring expedition where people fight like children with swords and crossbows and throwing rocks at each other. No guns, of course, that would be cheating. When Corwin uses a stone to make his enemy drop his crossbow, he ignores the crossbow and almost dies in the process. When he gets to the crossbow again, he smashes it! Why use a ranged weapon at all? Oberon made a blood raven out of a bit of Corwin's blood, to accompany and protect him in shadow. Why not make a bloody (pun intended) army of ravens? Wouldn't that have been better? And it just goes on and on. They never use the cards in this book, for example, after it was already obvious they can be used as communication devices as well as offensive weapons.

Nothing really made sense, in a nutshell. I am pretty convinced Zelazny was stoned out of his mind when he wrote this, but with some bad shit, since it never seems to increase his creativity. The ending was like a slap in the face, as after their victory, using armies of pedestrians and cavalry, a funeral procession for Oberon appears out of nowhere, with a lot of people and dragons. I kid you not, they had dragons, but their only use was decorative, like some sort of Chinatown celebration paper-mache things. And they got there not by treading the land like idiot Corwin, they actually came directly there. Oh, and since Corwin didn't feel like being king, they crowned another brother. Who, you might ask? Is it the brilliant strategist Benedict? Is it the loyal and strong Gerard? Is it the devious and aloof Julian? No, it's totally Random (another pun, couldn't help myself).

The next book in the series is the first in the Merlin cycle and the first book was written in 1986. It gives me hope that in 10 years Zelazny learned to fucking write!

I don't usually post animal videos, but this really is very cute. It is space related, as well, as it is taken by a camera in Baikonur's space center. Check it out!

The pattern (ahem!) becomes apparent once again: same lead character doing stuff in random order just to make the story be the way it was imaged by the author, same boring exposition, same artificial drama that could have been avoided easily if Corwin would have acted like a real character and not some cardboard placeholder of the lead, same stupid and obvious twist at the end, giving the name of the book even if most of it was about something else, same lackluster secondary characters, completely oblivious and helpless if not for the main protagonist and the mighty writer god. Indeed, the mock metaphor is not so far stretched when you think that in order to do anything worthwhile, people have to step on a pattern drawn on the floor and follow the lines exactly, without stopping, or they die. Maybe so we understand the villain better, trying to spill the blood of the children of Oberon, in order to destroy the existing pattern and build one anew: a book worth reading.

In The Hand of Oberon, Roger Zelazny again throws his Corwin character into a series of unlikely events, wooden dialogues and implausible behaviors. All strange events, that by all established rules should not be possible, are completely ignored by the characters until they appear relevant to some great reveal. Again a villain must walk the pattern and they must stop him, by posting guards, by walking the pattern after him, yadda yadda yadda. No one even considers taking a stone off the ground and hitting him on the head with it while they are hopping around the magical Hopscotch (not to mention a rubber bullet gun which would have solved everything in most situations). No one interrogates the corroborating witnesses or the people involved in the same situations until it is too late and they themselves don't act unless confronted later on in a sort of "oh, yeah" moment that is nothing but embarrassing.

The ending is just as muddled, with a scene that sees the villain put in storage for later use and a great reveal that had been obvious for a book and a half. No one seems to really care that the shadow realms have different rates of time passage either, so instead of using some trump to go to the fastest realm to talk or plan and return with entire plans made up, they sit around in feudal palaces in Amber, looking all important. I mean, Zelazny never truly describes their attire (unless it's some girl, and then he must describe her to the size of her cups), but I think that a kevlar shirt and some blue jeans and sneakers would have done wonders to the politics of the place. Oh yeah, kevlar probably doesn't work in Amber.

One book to go until the protagonist changes. At least there is some hope there...

Sign of the Unicorn continues where the second book ended and ends with another cliffhanger reveal that more or less has little to do with the content of the book! While I admit this book is slightly more interesting than the first two, the way the characters act and particularly the way Roger Zelazny completely ignores some of the main points in those books is becoming increasingly annoying. And just like the guns in The Guns of Avalon were a mere detail in an otherwise completely unrelated story, the Unicorn is something that just appears twice in the same book!

OK, enough ranting. This particular volume of the story (because it would be quite impossible to read the book without the first two, so in essence it is still the same book) is hinting about the origin of the strange forces attacking the realm, as well as explaining some more what had happened to Corwin and the court intrigues that led to it all. More of the siblings make their appearance, but their characters are reduced to conversation pieces in feudal Poirot-like instances, when they just come when bidden or do something that is instrumental to the plot going... in the same direction it was going. Instead of walking around with two Ingrams on his belt, Corwin continues to depend on his sword and reflexes, while sleeping underneath the same roof as his murderous and treacherous relatives. Instead of getting the man who sprung him from jail and using his unparalleled gift, Corwin seems to have forgotten about him completely. When he misses an important piece of jewelry that actually saves his life, he just abandons it and goes to do his usual business. And what about Bleys? After finding a solution for enhancing the power of the tarot cards, he just decides to use it once, on a single person. What about Oberon, man?! He's your dad!

Apparently, it wasn't enough ranting. It is kind of difficult for me to accept the layout of the story. Like any young adult movie recently, the author takes your sight and nails it to his narrow perspective, his favourite character and the things he feels he needs to do. Same unsympathetic shallow characters, same disaffectionate way of describing events, same predictable deus-ex-machina devices to promote the plot. Thank God these books are short!

The Guns of Avalon continues the story from the moment the previous book ended. Roger Zelazny is taking his Corwin character through some shadow land towards Avalon, where he might find the answer to his desire to claim the throne: an explosive agent that works in Amber.

His plans are soon thrown into disarray by several happenings. We meet the smart strategist brother Benedict, another blood relative Dara, we meet Gerard as well as learn a little bit more about the Amber world. However, the dispassionate style of writing as well as the dispassionate style of reading the book by its very author, made me feel close to nothing about the characters or events described. Again, I felt like learning nothing, as all the interactions between characters are very shallow and there is nothing described in enough detail to expand on the knowledge of the world or on some skill that the characters have. The author has attempted to show in the book that Corwin is a compassionate man, saving women from rape and wounded men from dying, helping his friends and being reluctant to dispatch or even harm his treacherous brothers, yet it all comes out like some guy playing a multiple option game: "Do you want to save the woman or keep going?" "Oh, what the hell, let's save the woman, see what happens". The ending of the book comes down brutally, solving several problems in a very lazy way, avoiding any controversial decisions that Corwin would (and should) have taken and introducing a magical nemesis that has no reason to exist that the reader would care about.

I am starting to feel that I've stumbled upon a dud. Two out of ten books to go (five if we consider that from the sixth book there will be a different main protagonist), and the only reasons I keep going are a promise to finish the series and my lack of strength for doing anything else.

Nine Princes in Amber describes a world in which only one place is "substance", the great city of Amber, while all others, including Earth, are just "shadow". Roger Zelazny doesn't really explain what is the difference, but we catch glimpses of the way Amber people can alter reality and that some of the things that happen in shadow cannot happen in Amber. Gun powder, for example, or perhaps even electricity. Great power can be channeled through tarot cards that hold the images of the children of Oberon or some other things, former king of Amber, while his numerous sons and daughters scheme and plan to take over the throne. The cards are drawn by a weird magician that seems to hold no political power, despite his amazing skill.

I took advantage of a flu that restricted me to bed in order to listen to the book in audio format, narrated by Roger Zelazny himself. While I enjoyed it, I didn't feel it taught me anything new. It was a pretty inconsistent story, as well. Princes and princesses and nobles, acting all smarty and aristocratic, dueling with swords and the occasional bow or crossbow, and some of the classic cliches encountered in this sort of context: like never killing your noble opponents, but imprisoning them or torturing/displaying them in order to demonstrate power.

In the end, the main protagonist remains a mystery. He starts with an amnesia, but soon he recovers his memory, making the entire memory loss kind of pointless. It is never quite spelled out who he is as a person, or what was it that he did on Earth. In truth, the book feels more like an introduction to the world of Amber, more like a teaser really, leaving the exposition of real character or description of the worlds to the following books. It is one of the first books from Zelazny, so maybe it will become better in the future. It is not explained why someone would want to rule Amber, either, as any other shadow world looks more appealing.

Even if I haven't fully enjoyed the story, I did promise a friend I would finish the entire Amber series, so we will see. After finishing it, I reserve the right to torture my friend in order to display my power by making him read something truly awesome and unsettling. I have not yet determined what yet, but a dark bird of my desire will carry my message and he will live in fear.

Zelazny himself died in 1995. I found a page written by George R. R. Martin, a beautiful remembrance of a mentor and friend. Apparently, he wrote the character Croyd (The Sleeper) in the Wild Cards series, one of the most interesting characters and appearing in many of the stories, even if very rarely as a main protagonist.

A blog reader asked me to help him get rid of the ugly effect of a large background image getting loaded. I thought of several solutions, all more complicated than the rest, but in the end settled on one that seems to be working well and doesn't require complicated libraries or difficult implementation: using the img onload event.

Let's assume that the background image is on the body element of the page. The solution involves setting a style on the body to hide it (style="display:none") then adding as child of the body an image that also is hidden and that, when completing loading, shows the body element. Here is the initial code:

<style>
body {
    background: url(bg.jpg) no-repeat center center fixed;
}
</style>
<body>

And after:

<style>
body {
    background: url(bg.jpg) no-repeat center center fixed;
}
</style>
<body style="display:none">
<img src="bg.jpg" onload="document.body.style.display=''" style="display:none;" />

This loads the image in a hidden img element and shows the body element when the image finished loading.

The solution might have some problems with Internet Explorer 9, as it seems the load event is not fired for images retrieved from the cache. In that case, a slightly more complex Javascript solution is needed as detailed in this blog post: How to Fix the IE9 Image Onload Bug. Also, in Internet Explorer 5-7 the load event fires for animated GIFs at every loop. I am sure you know it's a bad idea to have an animated GIF as a page background, though :)

Warning: While this hides the effect of slow loading background images, it also hides the page until the image is loaded. This makes the page appear blank until then. More complex solutions would show some simple html content while the page is loading rather than hiding the entire page, but this post is about the simplest solution for the question asked.

A more comprehensive analysis of image preloading, complete with a very nice Javascript code that covers a lot of cases, can be found at Preloading images using javascript, the right way and without frameworks

In my opinion, when a software you have been using for a long time changes the way it works and intrudes on your already existing installations, not only it is disappointing and mean, but it should also be illegal. Today I noticed that the links from my blog went to intermediate sites (I apologize for not noticing it sooner) like vindicosuite. A quick Google search led me to this link: Goodbye Sitemeter. Apparently, SiteMeter, a software that I have been using to show a views counter on my blog, has been acquired by a crappy company called News Company. I mean, this is the actual name, I am not making fun of you; it's like displaying "Dr Doom's Evil Lair" on your house fence (and not kidding about it). Without the company saying anything, the SiteMeter script added these click and contextmenu handlers on my links, redirecting to other sites, maybe with ads on them (I have AdBlock Plus installed and so should you!, so I don't know). Anyway, the moment I realized this I removed the script from my blog. I have to apologize again for failing to notice this for so long.
