Angular material - Cards tip

The fact is, that many times, we miss some obvious solutions that exist in the form of a simple attribute of an object and waste time using techniques that are no longer applicable because of the way technology and tools have emerged and those who do not recognize either end up with redundancies - in practices, techniques and attitudes.

So, when I read a question that was about managing a user login that was not returning to the login page after the user logs out or the session expires, I noticed the usage of a 'localStorage' object, which is the most common thing to do but if instead, the sessionStorage object were to be used, many knowledgeable would see that it solves some major problems straight away, without the usage of any special 'routers' (the software ones), it became clear to me that what the knowledgeable know is not through knowledge or more years of study but due to their experience.

AngularJS and Material (or for that matter, any technology that uses declarative forms of programming - declarative, in this context, does not mean annotations (as in Java) or attributes (as in C#), but as in programming through attribute (as in XML) values and directives (as in AngularJS)) are quite likely to put many of its programmer users in such situations.

One such instance that I wanted to share is inspired by another question on the same forum that was about deciding on AngularJS as a language to use in the project and what should be the criteria in making such decisions.

Rather than elaborating far too much on what could be bread and butter for many, suffice it to say, here goes !





Layouts, for the mobile, any-size-device, and the web, can be as simple as

<md-content layout-gt-sm="row" layout-gt-xs="row" layout-padding border="solid">

and the same layout fits for any device.

One of the most effective example of what should be the criteria for deciding on a language for a requirement (web or mobile app, though, only!)

White in Angular Material - tip

It is not a matter of black or white or any racial discrimination; it is quite simply a matter of the palette. Not that this indicates any taste or lack of it but because it is a colour, it must exist in some palette.

In Angular Material, the colour 'White' simply does not exist. It does, so to speak, but in the .backgroundTheme and to use it, you need to extend the grey palette (using the Google colour themes).

So, what do you do to colour your background 'white'? You simply create a new background theme and extend the palette whose hue you want to change or use! Like so,

var app = angular.module('modulename', ['ngMaterial', 'ngAnimate', 'ngMessages'])
    .config(function($mdThemingProvider) {
        var background = $mdThemingProvider.extendPalette('grey', {
            'A100': '#FAFAFA' // Not exactly white
            });
        $mdThemingProvider.definePalette('background1', background);
 $mdThemingProvider.theme('newTheme').backgroundPalette('background1').primaryPalette('background1');
});

The newly defined palette now can be used with any other palette like the primaryPalette.

But that is not all for, this, you can find in the issues list of the Material forum. Where it gets tricky is when you need to make AM recognize the colour, which Angular Material simply refuses to.

To make the new palette work for, say, md-toolbar, you need to wrap your md-toolbar in md-content for Angular Material to pick the colour from the theme.

Nuttify to contextify and be nuttified

The all new circular references



I guess somebody out there got really miffed (which is not surprising because the government as defined by political parties is usually to 'represent' masses (to get votes) and if the masses are nutcases then the government will be representing nutcases - a kind of a circular reference or a Catch -22, for progressive minded sane people) with how the bureaucracy and the government works, who keep blaming each other or asking for newer things; much like how the traffic cops usually know how to ask for docs that you don’t have and at times for bribes, for which you do not have the money!

With JsDom, it is similar. JsDom requires a particular version of NodeJS. 

Cool, so you get the latest version or upgrade with npm, right? Wrong. Because NodeJS simply refuses to respond until you nativize your Contextify.

But, why do you want to Contextify, in the first place? You don’t but you have to because you want to use JsDom.

But why do you want JsDom? Because you want to jQuerify.

But why do you want to jQuerify in NodeJS if you can simply use jQuery?

Because you want to jQuerify and Ajaxify the scripts in your HTML DOM so that you could trick the user into believing that you are using a server while using a browser but which in turn is false because it turns out that it is not a trick because even a browser is not used.

And to do all these Trickifys, you need your native IDEs like Visual Studio or xCode because you cannot compile native modules as they are machine specific!

Much like how nutcases who believe that you cannot survive by doing everything on your own without their help (imagine Nuttifys to make believe the nutcases to believe that they are not nutcases and you get the picture!).

Or, in much clearer terms, it is how some nutcases want to 'liaise' with you to fix a marriage or even a job interview for another while being already married. So why should the nutcases do so? Because...dash it, that is why they are nutcases, I can't possibly answer every question in this world, can I? Do some homework on your own.

VS2015, NUGet and NUnit Test Adapter bug

Is it a VS 2015 bug or a NuGet one - there are so many weird bugs whenever NuGet is used to install packages!

One such bug can be replicated by following the below bullet-ed steps:

  1. Install NUnitTestAdapter with NUGet (not the one with the WithFramework) in your NUnit test project. Set the test project's target framework version to "4.5"
  2. Check the Test Explorer and the target framework Settings of the project to ensure both synchronize.
  3. Add another project (say, for example, a class library to be tested from your NUnit test project). Set your project's target framework version to "4.5.2"
  4. Add reference to NUnit v2.6.4 (not v3.0 and not through NUGet) after downloading it from NUnit dot org and add some tests in your test project. 
  5. Build solution. You should see some warnings as below.

Open the Test Explorer window. from Test->Windows->Test Explorer and click Run all... No tests will appear in the Test Explorer because the tests cannot be discovered due to Build errors!!

Warnings are errors? Rhetorical question, of course.


Change the other project to target the same framework version as your test project's and rebuild.

Now check out the Test Explorer.

Given, when, then

One of the most fascinating games that humans play is Chess because it is not just a great mind game (or game of minds), it is also a game that enables many institutions and disciplines to function in a standard, universally acknowledged manner.



The fundamentals of Chess begins with the opening.

A chess opening is a sequence of moves that have to be played in a certain way (not as in 'discipline' that you have to play so but in a form much like how constellations are identified). There are many chess openings, as there are many constellations and design patterns (software), that are identified with the formation of the pawns structure, the placement of the other pieces in relation with the pawns etc.

Much like other conventions, many are puzzled as to why these openings emerge. One of the best way to understand the need for Chess Openings, as an accepted tool of study to play better and competitive chess, is by looking at one of the most popular Chess Openings of them all - the Dragon variation of the Sicilian defense.

The Sicilian - Dragon variation



As the name suggests, it is played by the player playing Black hence, the name 'Defense' but it is popular because of the high octane attack that it enables for Black on the Queen side of the Chess board.

The 'simulated' Dragon

Sicilian Dragon is one of the few variations in Chess Openings that can be explained clearly not just as an opening but why the Black Bishop serves its purpose at g7.

Here is a 'simulated' dragon (the theory is the same but the Bishop's position is not where it should be even though the diagonal remains the same) that loses black two to three moves that shows in the subsequent moves of the game how handy the two or three moves 'lead' time, also called as 'tempo', could have been for black.

Edit: This game was being played Live while I wrote this and I expected the 'tempo' was lost for Black and that White would capitalise on it, in the subsequent moves (if White had been enterprising and sacrificed with Ndxe6, fxe6, followed by Bxc5 !! recovering the sacrificed Knight, losing the White Knight on C3 immediately, but following with either Rxd6 or Bxd6, winning the exchange and a pawn and, of course, the simplest bxc5, Qa5 Ncb1 not Nb3 because Qxa3+ wins back a Knight with Bxc3) but...!


Given that the black Bishop was not in 'f6' but in 'g7'. 


And after just 7 moves, after move 15...Bf6, here is the resulting board position!

And after just another move, White is in total disarray.


The reason why it is called the Dragon !

Season's greetings, happy holidays and wishing a great happy new year for all my readers, followers, blogger family and friends ! :)

To be contd.

The Scrum Planner

Organizing the story board is usually dependant on the automated tool that is used. Often, when we use a real life story board like a white board, there are the same maintenance issues that usually pertain to communication. How to convey the right picture to the team?



When a task is slipping or lagging, do simple updates in stand-ups help or do you need an additional input? And if you do, where should the output, a graph or alerts, be conveyed to - the team, the management or presuming you are doing Scrum, with the ScrumMaster?


Role based users - the Scrum Planner is accessible only for Scrum-mers and the Sprint Planner only for the Sprint-ers !


The Scrum / Sprint Planner does just this - it helps you with a template of pre-assigned roles and responsibilities as defined in Scrum and as an experienced Agile practitioner, like me, would use it. Developed for Excel, this add-in is the complete solution for all your Scrum needs. Follow my blog to stay updated on the release date for this tool.

A case of too much thinking !

Imagine my chagrin, as I was watching "Pawn sacrifice", a week after mentioning it in another blog post, that most of the mentions of Life and other magazines in that post, were actually happening in front of my eyes.

They must have showed it in the promos that I had seen, was what I told myself but what about the creeps that are somehow beginning to look like stalkers to me, who invariably find a seat, (*next or near to me*, without this correction, it sounds quite pompous as if creeps should not find a seat even in a near-to-empty cinema hall) in a near-to-empty cinema hall?

This time the moron was more eager to make some munching sounds (for those not familiar with Indians, these are creepy types that go around thinking that if they 'irritate' others, they are either making them 'cute' to others, when they describe such moronity or that they are 'psyching' others.) as if to make me specially take note that 'it' was making those sounds!

Probably, the nutcase wanted to make a point 'tellingly' that 'it' had read my blog post because there was another similar creep, talking to its friend, outside the cinema, that "These are the kind of people that people hear about" and then repeated it, tellingly, even as the other remonstrated that once was enough! Quite clearly, a case of too much thinking beyond what their faculties could allow them.

The point is while you expect some to respond, if not favorably upon reading a blog, to at least not make my life 'stalked' and 'witch hunted'.

Co-incidentally, this is how the life of Fischer, the American Chess genius, was thought best to be described as by the filmmakers of the bio-pic. Strange!

Nevertheless, the biopic, as they call it, is well made.

Boris Spassky, played by Liev Schreiber, is almost like how we, my friends and I, used to talk about Spassky in our childhood - with awe and admiration.

To be absolutely objective, Schreiber seems to have got stuck with the introverted, controlled-in-a-repressed-manner roles - The Manchurian Candidate, even in the Omen - you name them and he looks "ready to look troubled" like an instant mix of "troubled and haunted by ghosts" pack.

But in all fairness, good enough a portrayal of Spassky to merit an Oscar for the best supporting role. I am sure the Russians would agree, too, and back him for the award.

And hey, in my previous blog post on the same topic, I had mentioned that Tobey Maguire looks more like Karpov than Fischer.

I.stick.by.that.verdict.

Made, then, only with having seen the promos and the ad banner but yet, how right I was.

This was not the Fischer that we used to visualize and probably, not as the screenplay writers must have either, because at many places, the dialogues clearly left me feeling that, "This line should have been spoken by some other type of character, in a lighter vein, but not this person."

I am almost certain that Fischer would have been appalled at how he was being cast had he been alive to see the movie but all credit to Maguire for having produced such a film and for having learnt Chess for the film !!

And they also show the real Bobby Fischer during the credits, bulky, tall and heavily bearded.

Myself, I am almost sure that no Hollywood producer is going to consider me for a role after this or even talk to me for not having praised one of their fraternity or if not praised, at least not have picked on the film at all.

But, as I said at the beginning of the post, the same applies to many blog readers, who are setting stalkers and witch hunters, however harmless they may be!

Stunning combination - a treasure!

I have often noticed that I am a very humble person.

It is not as if I am bragging about something that most of the fraternity that exist in my imagination would give their life for but seriously.

The fact is I am so because there are two sides that war away to nutty glory over me (Here! I am not bragging.) because when the one faction says "Give him some space", the other cramps me up with creeps; when the one says, he is so 'humble', the other brings out something in me to show I am arrogant; when the one says...you get the picture, right?

No matter what, the two factions are always there and here I am, with loads and loads of talent (at times, to the level of genius), commitment, willingness to put in hard work, tonnes of patience and humility, and not in the cover of Life or at the Oscars or the Emmy because these two factions insist on being the 'perfect' mother - father combination to me that even my real parents could not have been.

The fact is because of these two factions constantly at me for as long as I can remember, I have developed some kind of a defence mechanism within me that keeps failing the one or the other and so, I decided to carefully monitor where all I made mistakes (Btw, don't get carried away as one nutcase did because I don't usually make mistakes, in fact, hardly, or rather, I don't make mistakes at all. As I said, I am a humble person and such proclamations about myself are rare so don't think I am bragging again) when playing Chess and why.

Finally, I think I have made the grade as per myself. For, here I was sensing that this opponent on Facebook Chess that had bet 10K would definitely have something up her sleeve as they usually rig up a match with high stakes like disconnecting my internet or having a far higher rated player playing in her place.

But I surpassed myself because here I was playing one of the longest combinations that I can recall having devised.

Take a look at the boards that I managed to screen capture and see how the Bishop is placed at a6 to prevent me from castling on the King side. That is how long the combination was.

Board position 1

Board position 2

Board position 3

After board position 3, I played (let me annotate it as move 3) 3. Ng6 and black responded with ...Ra8-e8. And I played,

4. Qa4.

If 4...Nxf2 5. Nf-g5+ Kxg6 6. Qxc6+ Kf5 7. Qd7+ Re6 8. Qxe6++ !!


Board position 5

Board position 6

Board position 7

From here, evolves another combination that starts not with Nxe5+ but with (let me annotate it as move 8)

8
Qxa7+.
If 8. ...Ke8 9. Qb8+ Kd7 loses both rooks for Black with Nxe5+.


8. ...Kf6

If black had played 8. ...Ke6, 9. Nxf4+ black's Queen forked ! But this, losing the Queen, was probably the best way for Black.

9. Rxf4+ ! Rf5
10. Qe7 ++ !!

The depth of the combinations is what makes the game my best ever.

I am sure I can brag about this win even though it has not won me the world championships or any tournament prize.

I treasure it.

"Everest 3D", the movie

Little did I know when I did not put a box in an architectural design - The DropBox Facade pattern - (nothing as fancy as getting it patented but just a few boxes made in a word processor to resemble a design) that I had committed some hara kari or mata kari or hira kari (not sure which kari it was but the Tamilians will vouch that it must have been some curry).

I.did.not.get.that.feeling.when.watching.Everest.

;P

Just thought I would start it off on a different note because I am getting more bored with these creeps than "Jack the ripper" must have been when he did not find women to rip off that are bent on spoiling others' day at the movies or maybe it is simply because they speak. So how worse can it be that they are so shameless as to want to speak at all? Maybe 'they' were not prepared that I would go to watch "Everest". :D

That was the beginning of about 30 minutes of expensive 3D reels reeling away with only crunches of popcorns keeping me interested. I almost reached out to grab a handful from the bucket next seat.

It is only when the story of collecting some name and money for some kids back there as the reason for climbing Everest does the 'spirit' behind such expeditions make an impression.

It is not a gripping movie, not even a spectacular one, except for a few seconds of 'unbelievable' shots of views from 'impossible' angles of the heights and those, too, do not exhilarate because the mind tells you 'that is so unbelievably impossibly beautiful so must be graphically generated on a computer' but the eeriness of barren, white ice and vast stretches of mountain ranges with no signs of vegetation makes you wish if you should watch the movie at your home theater.

One of the best scenes, though, was the helicopter (a word that is supposed to trigger some anxiety because it gets used also as a 'chopper') landing at a camp and the subsequent take-off. The filming of it conveyed how incredibly tough it must be to fly the helicopter at that altitude, with the winds, but the same intensity is missing in the filming of the climb itself.

The 'storm' scene is beautifully filmed with the sheer speed of the change of the weather in those heights - "this mountain makes its own weather" - well depicted but possibly the movie is begging somebody to notice the clean aesthetics of the camera angles while showing the dead bodies and death in Everest, in an impassioned manner, without sensationalizing the tragedy, that is.

It did make me think 'tragic' more than a Greek tragedy has ever done.
