I started reading The Stranger on a recommendation. A guy told me the main character was a bit like me. Having read the book there is only one question I want to ask: How did Albert Camus know about me in 1942?

Joke aside, this a rather short book detailing a bit of the life of a Frenchman that doesn't feel much, is a rational person and doesn't believe in God. Therefore everybody around him thought him a stranger, hence the title of the book. Camus has a way of writing this in the first person, but in a way that seems both introvert and totally outside. The character describes everything he sees in neutral terms, proving he is both very observant and completely indifferent. When other people talk, he quotes them, when he describes himself talking, the character is summarising to the minimum, with no quotes, giving the impression he is a stranger to himself, hence the title of the book.

In the end, it felt like the last part of the movie The Mist. The same irrational fear of the different, coming from a shapeless mass of mindless drones, blindly destroying everything. In my view, the character manages to maintain his decency by rejecting the smallest gesture of resistance. But what do I know?

Would I recommend the book? It certainly teaches the reader something. It describes a way of thinking and of being that is different from most people. It explores several philosophical schools of thought, but you wouldn't know about it unless you read Wikipedia :). It is short enough to not bother anyone, though. Why wouldn't you read it?

I have seen there is a marked difference between me, a casual chess player that has become interested in the theory of chess, and other people of my level that do not try to understand the theory. I usually beat them with the help of some of the information that lingers in my head. At the same time, there is an even greater difference between me and people that actively play chess online, not only when a colleague becomes interested in playing. They crush me immediately.

It seems to me that in order to grasp the chess theory I must also back it up with practice. So I have decided (after quite a while of fearing it would either become addictive or that I would suck terribly) I've made the first step and played a game there. And I won! Woo hoo! Unfortunately I played horribly and only luck can be attributed to my victory. As always, I've analysed the PGN and here it is. You will understand the shame of my victory (yes, it can happen) when you get to the end. Enjoy!

This will be a short blog post that shows my error in understanding what Javascript maps or objects are. I don't mean Google Maps, I mean dynamic objects that have properties that can be accessed via a key, not an index. Let's me exemplify:
var obj={
  property1:"value1",
  property2:2,
  property3: new Date()
};
obj["property 4"]="value 4";
obj.property5=new MyCustomObject();
obj[6]='value 6';
console.log(obj.property1);
console.log(obj['property2']);
console.log(obj["property3"]);
console.log(obj['property 4']);
console.log(obj.property5);
console.log(obj[6]);
In this example, obj is an instance of object that had three properties and others are added. First the declaration notation is JSON like, then any object can be assigned to a property via two notations: the '.'(dot) and the square brackets. Note that the value of 'property 4' and of '6' can only be accessed via square brackets, there is no dot notation to escape that space and obj.6 is invalid.

Now, the gotcha is that, coming from the C# world, I've immediately associated this with a Hashtable class: something that can have any object as key and any object as value, but instead, a map is more like a Dictionary<string,object>.

Let me show you why that may be confusing. This is perfectly usable:
obj[new Date()]=true;
In this example I've used a Date object as a key. Or have I? In Javascript any object can be turned into a string with the toString() function. In fact, our Javascript map uses a key much like 'Sat Jul 14 2012 00:07:00 GMT+0300 (GTB Daylight Time)'. The translations from one type to another are seamless (and can generate quite a bit of righteous anger, too).

My point is that you can also use something like
obj[new MyObject()]=true;
only to see it blow in your face. The key will most likely be '[Object object]'. Not at all what was expected.

So remember: javascript properties can be any string, no matter how strange, but not other types. obj[6] will return the value you have set in obj[6] because in both cases that 6 is first turned into a string '6' and then used. It has nothing to do with the '6th value' or '6th property'. Those are arrays. The same for a Date or some custom object that has a toString() function that returns something unique for that object. I wouldn't use that, though, as you would probably want to use objects as keys and compare them by reference, not string value.

Greg Bear is the type of writer that I just have to love: he writes hard SciFi, but easy to read, he doesn't bullshit the reader with too much technobabble and, even if his writing is by no means simplistic, he doesn't bore you with how some person or another feels unless it propels the subject forward. Blood Music is also of a subgenre that I love: global pandemic, so I have to also love the book. So take that into account when you read my review.

The book starts with a preposterous idea: that cells can become intelligent. A brilliant scientist, but one that has always cut corners to get around, discovers this almost by accident and... well... cuts a few corners. The result is something that feels like John Saul's The God Project, but soon leaves it and reaches for the stratosphere. The end is typical Greg Bear, astounding and megalomaniac.

Blood Music has some flaws. One of them is that it is really a very short book, an extension of the original 1983 short story that won the Nebula. The other is that it is written in 1983 (similar to The God Project) and so the science background is both grandiose and a bit obsolete. But it is a good book and one that ponders on the significance of identity, thought, society and ultimately: the essence of reality. I've read it in about three days, so you have no possible excuse for not trying it.

I was in the mood for horror, something really disturbing and hopefully on the sci-fi side, and so I went scouring the net for good horror books. Origin, by J.A. Konrath, was suggested by some guy or another, so I started reading it.

The problem is that the book is not much more than an easy thriller. The writing doesn't suck, but neither does it shine; the subject is intriguing, but treated in a screenplay fashion, with not much depth and only a few characters; the book is easy to read and really short; the plot has numerous holes in it. But worst of all, it doesn't really scare! While some of the scenes were - let's say - gory, they were not horror, but rather expected consequences of previous actions.

What is it about? The United States government (who else, tsk, tsk, tsk) has found a strange sarcophagus while excavating the Panama canal. For a century the secret is kept and the subject examined in a specially built facility underground. In the sarcophagus is a massive creature with red skin, hooves, horns and wings. After 100 years of slumber, it awakens. What is it? A devil, THE devil, an alien, a strange prehistoric creature? You will have to read the book in order to get an answer to that question.

Bottom line: I read it in less than a week, didn't hate it, didn't love it, it was good for passing the time, but I would not recommend it for anything but a vacation, to read on the way or in other boring moments.

I usually comment on big political events in my home country of Romania, although I am not really that involved. The thing is, since the end of the Communist era, we Romanians have chosen worst and worst leaders as time went by, every time being certain in our righteous beliefs that the new guys will be better. Hell does seem to be paved with good intentions after all.

A quick recap for those of you who are not Romanians (or don't share my skewed views on reality). After Nicolae Ceausescu (the dictator, remember him?) was gracefully deposed by way of angry mob and firing squad, we chose Ion Iliescu as our first president. From the initial tableau of a murderous dictator being replaced by a fighter for freedom the image shifted over the years to a delusional old man being replaced by a shrewd manipulator of the system. We did not like that, although the people were pretty used with a single president for the rest of our lives and elected Ion Iliescu twice. Luckily our law says there are only two consecutive presidential mandates for a single person, so we had to change the guy with another.

Well, if we have to change the president, we might as well keep the party, we thought, still entrenched in our habitual maintaining of the status-quo. In order for that not to happen, all the other parties coalesced into a big ball of shapeless mud and rallied behind a single candidate, a university professor, an intellectual. And he won. Welcome to the glorious era of Emil Constantinescu, who, besides being a dusty professor who had no clue about politics or management of any kind, despite being a propaganda secretary for the Communist party in the past, he was a fool with no balls. During his single mandate nothing was done at all, since he didn't know what to do and the ball of mud, now in power, disintegrated immediately after elections. Constantinescu's party, a historical party, important in the political landscape of Romania, all but vanished into oblivion.

Yay! We get to elect our main guy again. Let's go with what we know: Ion Iliescu, the former Communist, posing as a freedom fighter, equally loved and hated. Personally, I think he was OK. You can't be a politician and not be a bit corrupt or manipulative or even downright evil, but Iliescu had style and, while he wasn't an angel at all, he rarely did obvious blunders of incompetence, stupidity or lack of self control. No wonder they chose him an honorary president of the party, he was their only real politician! Now over 70, Iliescu got another mandate before a new champion of justice entered the arena!

The next iteration, two people fought for the most visible position in Romania: Adrian Nastase, a corpulent minion of Iliescu, with an intellectual allure and a lordish demeanour, versus Traian Basescu, a populist fellow, former ship captain and behaving mostly like a Romanian Popeye, championing for democracy and the people in the most crowd pleasing ways. It was tight, so tight that the real results of the election will forever be uncertain. Basescu won, while Iliescu's party won everything else. Nastase's allure and demeanour made him appear too arrogant in front of the populace and they could not possibly elect someone who looks down on them. Also, all that façade with no intelligence to back it was ridiculous.

We have now reached "modern times", the actors having relevance today, after two of Basescu's mandates. You see, as president Basescu immediately moved to impose his position over parliament and senate. If the people have chosen him as their champion, then it would make no sense to have his party as the opposition party. He wiggled his way until his party was in power, through all kinds of tricks and alliances. During his reign, Basescu frequently overstepped his presidential responsibilities, being, again, both loved and hated for it. Adrian Nastase, former Prime Minister, was almost forgotten, like any loser in Romanian cock fights.

Fast forward to today. Basescu is at his last legal mandate. The economic crisis and the abuses of both himself and his party have left him without political capital. Attacked from every side, the two main opposition parties having united into a single political entity (even if their ideological platforms are completely different), Basescu and his minion Emil Boc held on to power as much as they could. Until anticipatory local elections were forced and finally removed Basescu's party from rule. He is next. Again democracy has prevailed.

Or has it? The opposition parties are led by arrogant, relatively young politicians Victor Ponta and Crin Antonescu, more mouth than political clout or experience. Happy to have won the anticipatory elections they see the period until normal elections as an opportunity to consolidate their power in order to have a stable mandate. Instead, they fall into traps (some of them really obvious) at every step. Like the old Romanian fighters, Basescu has retreated and poisoned the wells behind him. If the local elections showed the lowest possible confidence in Basescu's party, now at every mistake of the new power, that confidence seems to grow. So what happened?

First Adrian Nastase is sentenced to jail for stealing as much as he could in a ridiculous and stupid way. The first major politician to go to jail, former prime minister, the mentor of now party leader Victor Ponta, almost president (remember the close elections), he not only loses badly, he attempts suicide when the police come for him... and he fails! He is the laughing stock of the entire country. Yes, that's how we are, if someone tries to commit suicide and fails we laugh at them for being stupid (sometimes we show them how its done, to demonstrate our superior intellect).

The silly thing is, even with Nastase going to jail, I would still choose him over Basescu as president. That is how high hate can rise in this story.

Second Victor Ponta, a doctor of political science, is accused of plagiarism in his doctorate. We could talk of this for ever and still find something new to say, but the truth is that everybody in Romania plagiarises in doctorate thesis. The teachers themselves point towards places where one should gather material for their papers. If you wrote something original (in that rare case you actually did something for yourself instead of Googling it and translating it) the teachers tell you you need five times as large a paper, so they point you to chapters in the books of the people that taught you in university. Take one from three of their books, write a conclusion and you have your five fold quantity of wasted paper. It's how the system works.

Of course, instead of just laying down and accepting such an obvious fact, Ponta half denied it (aka failed to properly deny it and again lost face), then in a wave of brutal and ridiculous moves, dismantled the plagiarism committee and even the Constitutional Court. Well not exactly like that, but it certainly felt like that. The populace is in shock, of course: didn't we elect someone in order to not have fists shoved in our mouths?, they ask.

Finally, as the conflict between Prime Minister Victor Ponta and President Traian Basescu cannot continue like this, the coalition of victors (yes, yes, a pun, sorry!) moved to impeach Basescu. And they did, only now, by law, a popular vote must be organised to see if they can remove the president from office. And guess what! Even if there are virtually no chances for Basescu to remain in seat, there will be so many votes in his favour that the power parties will lose immense political capital which will hurt them badly in the coming permanent elections.

In this light, a question begs for attention: Isn't it possible that Basescu allowed for the party change just after he carefully prepared his attacks against the opposition? Wasn't this all a big political entrapment? And of course it was. Basescu has proven himself a shrewd manipulator himself, a "playing president" as he himself imagined he would be. Instead of winning prematurely, the eager beavers stepped right into it and failed miserably. Remember what happens in Romanian politics when someone fails at something?

So let's review this long long story. We changed a dictator with a freedom fighter, only to find him a former Communist with great political skill. We replaced him with an intellectual, only to find the guy incompetent. We went back a bit, electing a 70 year old man as president for the third time, then replaced him with a populist alpha male with psychopathic tendencies, which now will be replaced, probably, by a loud mouth fool that fell into every trap that was set for him (and his buddy Ponta) Am I the only one who sees this trend as going down?

Another song that I've been listening obsessively for the last day or two. I am fascinated by the mouth on that girl. So filthy the words, so beautiful a smile, so machinegun the speed. Not something that I would have associated with Manhattan , either. Here is the video, I will paste the lyrics below, because you may not understand them from the song alone :) You may also understand why at first I didn't believe it was on a TV music station, where I heard it the first time.



Hey, I can be the answer
I’m ready to dance when the vamp up
And when I hit that dip, get your camera
You could see I been that bitch since the Pamper
And that I am that young sis, the beacon
The bitch who wants to compete and
I could freak a 'fit, that pump with the peep and
You know what your bitch become when her weave in
I just wanna sip that punch with your peeps and
Sit in that lunch if you're treatin'
Kick it with ya bitch who come from Parisian
She know where I get mine from, and the season

Telling them you made some (made some)
Saying you're grinding but you ain't going nowhere

W-when-when I premiere?
Bitch, the end of your lives are near

I have a pretty bad opinion of Apple products: expensive pretentious gadgets that impose all kinds of restrictions upon the user. So bad, in fact, that I delayed saying anything about the iPad I got from work until I was certain I wasn't completely biased. I mean, so many people using iStuff can't be wrong; it had to be me.

But today the bubble just burst. I lost so much time searching for simple apps that open one type of file or another, only to be reminded again and again that Apple doesn't support that kind of file. Why does Apple need to support anything? I just want the app that opens it. The "there's an app for that" meme doesn't seem to apply to most of what I want!

Basically, what I desire is to have access to the files I copy to the pad with the best software available for those files. I don't want to use iTunes, I don't want to split my files based on type and most, most of all, I want to either use paid or free applications, not something in between, like a diseased mutant.

Oh, maybe you didn't know about the "freemium" ecosystem on the iPad. You go to their AppStore application (a software so bad that it forgets the options you chose if you change the search string) and you select if you want applications for IPad and/or IPhone, free and/or paid, based on user rating and category, etc. You see something free that you like, you install it, only a button away, then you start using it. It may be a game or a utility and at first it is all well. And when you want to get a better weapon, continue to the next level, finish the workflow a utility is supposed to support, you get a "buy the full version". This is called "freemium", a disgusting offspring of shareware applications that makes that look benign.

You have the option to "jailbreak" your iPad. There is an app for that (hee hee), many in fact, that hack your Apple jewel and turn it into something that you have full access to. You get a Linux like command line, a place where you can get a lot of the software you want and need, all a button away. Apple does not like that. At every step of the way they will try to fix their broken machine in order to stay broken. So no, my naive friend, the iPad doesn't work like a computer not because they couldn't do it, but because Apple forced this on you. If I didn't give the pad to my wife, I would have jailbroken it for the principle alone.

But why? would somebody ask. What has Apple to gain from maiming their own device, creating crappy applications for a small tablet that costs as much as a decent laptop? It is all because of the AppStore, of course. If they can make a zillion assholes sell you useless junk that my 386 computer did better in the day, they can share a bit of the profit. So not only they rip you off with their cheap device made by labouring children that barely get something to eat, they keep getting money off of you, a trickle at a time. And, because you don't have complete access to the machine, they can force whatever software they want, unsecured, crap, cheap, but one that you can't hack, can't crack and can't use until, yes, you pay them.

Today I searched for an hour for an iPad application that would read .lit files. Yes, the Microsoft ebook format. There are CHM readers, why can't there be LIT readers? Apparently the "Steve" way is to convert the lit files to .epub (on the computer that I have to have in order to use the pad) and then copy them (with iTunes, not directly) in the ebook reader sandbox. If it happens for me to have a movie or some text files and maybe a picture in the same folder, I cannot access it with the epub reader, I have to move everything in its place.

Luckily I found something that even slightly resembles what I need: FileApp it is called, it allows for me to copy files to my Pad via FTP. I can open them, and that means they get copied where the program that uses them needs them (even if they are 4Gb of DVD image). Not a perfect solution, obviously. And you still need applications that can open the files you own without having to convert them.

I hope Windows Surface will be a huge hit, something that would sweep this crap away. Apple can buy Facebook and go to hell together to rot. When Android will be what Linux is today and Windows will be.. well, Windows, and the iPads will be relegated to the bottom, with all the other mini game consoles, then I will be content.

Programming Game AI by Example is one of those books that would have changed my life had I had read them when I was 15. Mat Buckland is taking a really high tech portion of game making and turning it into child's play. With source code!

From the very beginning we are being told that AI in games is different from what we would normally associate with Artificial Intelligence. AI in games is the thing that makes game agents look smart, but let the user enjoy the game the most. In other words, something that seems smart, but is just stupid enough for you to continue playing.

The book is comprised of ten chapters, heavy with code, but very well structured. The main tool in use are Finite State Machines, but we first get a mechanics physics lecture in chapter 1 where we learn what a vector is and how to normalize it and how to use this in the game physics. Moving to chapter 2, we learn what a state machine is and how to optimize memory by making each one a singleton, how to compose them and why more exciting aspects of artificial intelligence, like say neural networks, are not used more in games. We delve further into methods to optimize what we have learned to make it practical: prioritized dithering, partitioning, BSP, quad and oct trees, fuzzy-Q logic, cell space partitioning, all with code examples, in chapter 3. Chapter 5 is reserved for graphs, Dijkstra, A* and such. Chapter 6 goes into integrating Lua into your games, as a good tool to define and tweak the innards of your game before compiling it all for performance into a single code base. Raven, the example game engine, is detailed in chapter 7. Path planning is described in chapter 8, complete with many optimizations and tricks to make an algorithmic movement of units look natural and smart. Chapter 9 is about goal driven agent behaviour, where we learn how to make an agent define goals and act upon those goals. The composite pattern is suggested as a good solution for goals within goals. We end with a very interesting chapter about fuzzy logic. The basis of this is to fuzzify a situation, infer a behaviour, then defuzzify into a usable algorithmic value.

The bottom line is that this is a very easy book to read, explaining matter-of-factly how to easily create the intelligence in games like Fifa or Counter Strike. The code examples are extensive, but not necessary to understand the gist of things. At the end, it is both a fascinating and intriguing read as well as a good reference book for when you actually need this stuff.

I end this review with a quote from Dijkstra that was also mentioned in the book: The question of whether Machines Can Think... is about as relevant as the question of whether Submarines Can Swim. Very nice book and a recommended read.

Yesterday I wanted to upgrade the NUnit testing framework we use in our project to the latest stable version. We used 2.5.10 and it had reached 2.6.0. I simply removed the old version and replaced it with the new. Some of the tests failed.

Investigating revealed all tests had something in common: they were testing if two collections are not equal (meaning not the same instance) then that the collections are not equivalent (meaning none of the items in one collection is found in the other), yet that the values in the items are the same. Practically it was a test that checked if a cloning operation was successful. And it failed because from this version on, the two collections were considered Equal and Equivalent.

That is at least strange and so I searched the release notes for some information about this and found this passage: EqualConstraint now recognizes and uses IEquatable<T> if it is implemented on either the actual or the expected value. The interface is used in preference to any override of Object.Equals(), so long as the other argument is of Type T. Note that this applies to all equality tests performed by NUnit.

Indeed, checking the failing tests I realized that the collections contained IEquatable types.

I loved the first Avatar animated series. It was deep, funny and yet innocent. A perfect kid show, but one in which an adult could find finer underlying levels of understanding. So it is no wonder that I eagerly awaited the release of Legend of Korra.

Now, that the first season is over, I can have an opinion on it. The show is not about a little kid anymore, it's about a teenager avatar. She, for she is a female, lives in a technological steampunkish world, something that is pretty hard to understand, considering she is the granddaughter of Ang, the hero of the first series, and it all happens merely 70 years afterwards. The innocence of childhood is replaced by the impetuosity of teen age, complete with mood swings, romantic feelings and a strong false sense of infallibility. The elemental countries are now united, so the only possible threat can come from a terrorist organization. There are moments of real fun, but not that many.

Bottom line: it's a completely different show! While in the first Avatar one could find strong moral values underlying what the characters did and the viewer would watch the show waiting to see what would Ang do next in the face of overwhelming adversity, now the focus is on what the avatar girl is feeling when she is not the center of attention and how she gets angry and motivated to use power to solve things. Not something terribly surprising in an American show, but really disturbing in a sequel to such beautiful a series.

So, while the show is nicely animated, the world interesting and the story passable, the overwhelming feeling I get is disappointment. I really do hope something will come out of the next seasons, which I will watch religiously, but let's face it: I do it for Ang.

I was not going to write a chess post so soon, as I haven't really been playing lately and it might give the impression that I am either a good player or that I lost interest in other areas, like software developing. (I assure you, I did not, as I still waste spend most of my time at work, coding).

However, this opening seems a natural continuation of my previous post on the Sicilian Wing Gambit. There the b pawn was moved to b4 to counteract Black's attempt to control the center with c5. In the Polish opening, White starts directly with b4, denying Black moves like c5 and even hindering the development of their queen side knight.

The Polish, Sokolsky or Orangutan opening has been successfully used by international master Alexey Sokolsky, hence the name. He was not Polish though :) and I don't even care why someone would name a chess opening from an ugly orange ape (the video below explains it, though).

I will attempt to use several resources in this post. First, a PGN of the opening as a statistic of chess games played starting with b4.

1. b4 e5
(1... d5 2. Bb2 Nf6 3. e3 Bf5 4. Nf3 e6 5. a3 {This line ignores the White pawn on b4 and develops normally.}
(5. b5 {Moving the b pawn forward hinders the development of the queen's knight. Black is forced to either challenge the pawn, easily defended by the a and c pawns, as well as the bishop and knight, or develop their knight to d7.})
)
(1... Nf6 2. Bb2 e6 3. b5 {With White's pawn on b5 and Black's on d7, the knight on b8 is effectively out of the game.} d5 4. e3 c5 {Taking en passant would be a mistake, as it would free White's knight.}
(4... Be7 5. Nf3 O-O 6. c4 c6 {White has a thematic move: c4, with Black forced to protect the d5 pawn and lose avenues for development.})
5. bxc6
(5. c4 {Now it would be Black's turn to blunder in taking the c pawn and helping the White bishop develop while losing a center pawn. Black is not looking good with most their pieces having reduced mobility.} Be7
(5... Nbd7)
(5... b6)
)
5... Nxc6 {At this point Black is looking good, controlling the center and having more minor pieces developed.})
2. Bb2 d6
(2... Bxb4 3. Bxe5 Nf6 4. Nf3 O-O 5. e3 {The other common continuation. Black takes the pawn on b4, but loses a center pawn. At the same time Black develops a piece while forcing White to move twice - and later three times, maybe - the strong fianchettoed bishop.})
(2... f6 {Protecting the e pawn and blocking the White bishop's attack diagonal might look good, but it is robbing the Black night of its natural development square and weakening g6.} 3. b5 d5 4. e3 Be6 {Here Black has control of the center with a strong pawn structure, but can they hold it? The knights can only be developed on awkward 7th rank squares, the bishops have to wait for them and the queen has nowhere to go. The computer gives a complete equality between sides, but is it?})
3. e3
(3. c4 Nf6 {Transposing to the English opening} 4. e3 Be7)
(3. b5 {The natural continuation of b4, blocking the Black knight.} Nf6 4. e3 Be7 {Again, an awkward position for Black: everybody has to wait for the knight on b8.})
(3. e4 Nf6 4. Nc3 Be7 5. Bc4 O-O {Two bishops aimes straight at Black's king.})
3... Nf6 4. c4
(4. Nf3 Be7 5. Be2 O-O 6. O-O {Another variation similar to many before.})
4... Be7 {Consider this the main line, yet with less than 100 games played in this move order.} *

What we can see is two major thematic moves for White: b4-b5, blocking the development of the Black knight. The other is c4, protecting b5 and challenging d5. If Black takes (d5xc4), it loses a center pawn and helps develop White's light bishop. Also, after b4 and the dark bishop fianchetto, a common White move is e3, helping in completely domineering the center dark squares.

As Black, one can observe a tendency to go for the light squares. If White's pawn reaches b5, the only real square where the Black queen knight can develop is d7. That means that the d pawn cannot depend on the protection of the queen all the time and the light bishop will have to develop first or remain blocked by the knight. In the last game in this post, for example, one can notice Black immediately sacrificing the light squared bishop for White's king knight, relieving some of the pressure on Black's king side and giving freedom for pawns to occupy e6 of even f5.

Note that even if I have a huge database at my disposal, most of them are not annotated at all (like these three). There is a lot of chess knowledge out there that just waits to be analysed, digitized and shared. Help me out if you can!


In this game Black quickly realizes the light bishop is going to be hindered by the queen side knight and trades it off immediately, then develops the knight to d7 while the d pawn is protected by a pawn chain.

And the final resource, a video explaining how one should play against the Polish, from Black's perspective.
[youtube:EQQugBzKefE]

As a conclusion, I liked this opening. It is uncommon for a reason, as it is rather slow and risky. White has the advantage of the first move, they should not waste it on side pawns. However it does seem more manageable than the Sicilian Wing Gambit and can easily transpose in the English opening, which I haven't played, but is in heavy use. What I did't like at either this or the wing gambit is a lack of traps. There probably are a few, but I would have to find them myself. I hope you liked it, too.

Please let me know which formula for a chess blog post you like more. I've tried several and I will continue to try in the future, but I would like some feedback from people who read about chess on my blog. Thanks!

Sometimes, in the subway or when I get a little bored I take out my trusty cellphone and play a little game of chess. The games are not spectacular or even smart, but I feel I learn a lot by the subsequent (and a lot longer) computer analysis of the game. Without further delay, here is one of them:

It was not a complete surprise, but I did not expect it, either: the switch statement in Javascript is type exact, meaning that a classic if block like this:
if (x==1) { 
  doSomething() 
} else { 
  doSomethingElse(); 
}
is not equivalent to 
switch(x) {
  case 1:
    doSomething();
    break;
  default:
    doSomethingElse();
    break;
}
If x is a string with the value '1' the if will do something, while the switch will do something else (pardon the pun). The equivalent if block for the switch statement would be:
if (x===1) { 
  doSomething() 
} else { 
  doSomethingElse(); 
}
(Notice the triple equality sign, which is type exact)

Just needed to be said.

As part of the blog revamp I've modified the styling and code for the board that displays chess PGNs and added file letters and rank numbers as well as highlighting of the last move. I've also sped up the move animation a little. Hopefully it will be more helpful this way.

Also, I noticed that the link overlay I added for external links was behind the YouTube videos. Thankfully there was a relative simple fix, albeit one that had to be made on each post. On this occasion I've created the new 'video' tag that complements the old 'picture' tag which applies to anything visual, be it video or just images, I've refreshed the videos that were removed, updated all the links to the new YouTube iframe embedding mode.

The tag system is something that evolved organically on this blog, starting with 'programming' and 'misc' (which actually is anything not related to programming) and ending with such ridiculous stuff like the 'picture' tag or the 'essay' and 'personal' tags, for which even I get confused about what they are. Perhaps some day I will reorganize it, but until then (and until Blogger finds a way to remove the restriction that only up to 50 posts can be affected by tag changes) try to remember the main tags on the blog:
  • programming - refers to anything related to software development
  • misc - unrelated to software development
  • software - posts about specific software
  • music, movies, books - relating to music, movies and books
  • picture - containing embedded images or video
  • video - containing embedded video
  • administrative - related to this blog
