So a buddy of mine is going back to college to get a BS in Comp Sci in a few months, and I have a really dumb question. He decided to start with the MIT lecture last night and I guess it starts off having him use Python. I don't know the first thing about Python or the Python Shell application it was having him use (Or any scripting language for that matter, I'm a newbie C# guy). He was having a problem trying to "understand" how he would actually use this in the real world. By that I mean, if he saved a file and ran it, a command window would pop up and immediately disappear, even though the script requests user input.

I also think part of it for him is he expects to be creating full blown desktop applications, but you need to learn to walk before you can run. Most day-to-day users would poop themselves if they had to deal with the command line in any way.

He was just texting me about it this morning as I was getting ready for work, so I didn't have a chance to sit down and try to learn anything, though I figured while he's taking this course I probably should too

http://kivy.org/

Its got a few rough edges in terms of the fact its a young project and evolving fast, but its very actively maintained and actually achieves cross platform (including ios(!) and android) really well.

And the apps look pretty nice if you like black things.

Just a end-of-day frustration I just found in our code:

Resulting SQL:

Yes. That's two string substitutions in a row, with no other instructions inbetween. The Double Percentage (%%) which is commonly used to do a literal '%' is in place so it can be substituted later.

This is tame. Some of the PHP I've been forced to maintain stuff, has had these sorts of substitutions, pulled directly from the command line using register globals and no cleansing. Its.... terrifying, and worst of all, the boss doesn't understand why its bad and is incredibly resistant to me refactoring it ("Every time you code, the files actually get shorter, thats not productive!")

It probably also has to do with the backends. It's ok to have a super fast nosql database that isn't 100% consistent and sometimes loses data when it's Facebook, less so when it's government records.

That and they can't really hire rock star engineers and use bleeding edge technologies.

Complexity in the name of security is fine. Validation and general sanity making can be complex. Complexity arising out of makework, pattern madness, incompetence, obsfucation or bad design, not so much.

For what its worth my first coder job was doing Cobol poo poo in the early 90s. Some of those codebases had literally millions of lines of turgid horrible code. And it was *never* complex, because honestly its such a loving primative language you just avoid complexity at all costs because Cobol isn't any good at it. In a way thats also sort of the appeal, its a very workman like simplistic but verobose language that rewards simple readability over terse cleverness. But its also RSI inducing and you become sad that all that cool poo poo like OO/functional/etc you learned at school is completely out of place in that world. Its like prostitution, you can get rich off cobol (Theres a LOT of it still out there that needs maintaining, but all the cobol greybeards either moved on to make java terrible or retired/died of old age.) but you'll hate your life doing so.

edit: lol I just noticed a COBOL job on seek offering $58 an hour. Theres about $100/h missing off that number there buddy, cos gently caress doing that for jr coder wages. The job will still be open in a year, my prediction.

I actually hate teaching Python and transition to Java as soon as possible (for a variety of reasons). As you said, Python feels more like a really convenient language for prototyping, getting quick little things done, and whatever web/scripting/etc stuff that I don't know about but am aware is quite useful for others.

Half the time Python honestly builds in a lot of arbitrary and confusing training scars for kids that can be annoying to deal with when they learn the more popular industry languages.

Have you actually worked outside of high school education before? We actually blacklist people infected with java madness where I work. The 9 level deep pattern factory singleton visitor blah blah sort of crap encouraged in Java is completely incompatible with the agile techniques the industry is moving in. Hell its not even that compatible with where computer science is heading anymore (protip: Shits getting functional).

If your trying to teach kids to be good Bank programmers who 30 years ago would be slitting their wrists to millions of lines of turgid cobol and now are slitting their wrists to hundreds of thousands of lines of turgid java, then sure thing.

But if your actually trying to teach kids to have a love of computer science, why the gently caress would you be moving from python TO java?

I would like to create a GUI with PyQt that displays a 2D numpy array. Is this relatively straightforward? Is it better to convert the image to a QPixMap or a QImage? Or is it better to try to embed matplotlib into my PyQt GUI? I'm creating a slider so that the displayed image can be switched rapidly, so I was imagining that refreshing matplotlib over and over might be suboptimal, but maybe not?

I'm still fond of Kivy for doing GUIs. Its all bleeding edge stuff, but its cross plaform as hell, and very pretty.

Personally I'd be trying to prerender those images as much as possible,, and just load up a background buffer with the next (and previous if the slider goes both ways) images so you can just blit them across.

edit: If these datasets are really big, you might even want to consider setting up your bitmaps using something like cython with static typing which can win you some pretty huge speed-ups if done right.

With Apple introducing it's own 2d game framework for iOS, cocos2d for iOS is all but dead. I know they had a big push to make javascript it's primary focus, so maybe that will keep it around, and the tutorials may all start switching to JS...

That I doubt. Cocos2d for ios has the lionshare of the market, is conceptually multiplatform via cocos2s-x and its html5 spin-off and has zynga as the 700lb gorilla backing it.

Apple could make a big impact by bringing scene kit across to the ipad which would pull the rug out from cocos2d feet by delivering proper 3d, (There is cocos3d but its a bit of a mess and doesnt support shaders making it pretty ancient and lovely), but at the moment gamekit is the minority platform for the iphone right now. Its not widely used, hasn't the tooling cocos2d has, nor is it as capable. Or as easy actually.

I actually recommend you check out JS. For all you may have heard otherwise, it's actually fairly Python-like and I often feel like I'm writing Python in JavaScript.

That said, I tend to use Mozilla JS in most of my projects which gives me fun stuff like destructuring assignment, let, and list comprehensions / generator expressions:
JavaScript code:
let foo = ["a", {"b": "c"}, "d"];
let [a, {"b": c}, d] = foo;

let bar = [x*2 for (x of [1,2,3,4,5])];
for (let a of bar)
    print(a);

Presenting......... The worlds most ill-concieved web framework, Appy!

http://appyframework.org/principles.html

quote:

appy.gen works at a higher level of abstraction than most other frameworks or approaches. With gen, you are not going to write a function that returns dynamic HTML when some URL is hit. You are going to define classes and relationships, and methods will be like hooks that will react when some events occur (an object is created, edited, deleted, etc). You don't have to write a single line of HTML, CSS or Javascript to write basic Appy applications. Only pure Python. This is what I call conceptual. But unlike most conceptual approaches, you will not draw any diagram or anything that is not Python code. Pure Python, pure simplicity, no repetition, no transformation: optimal efficiency, optimal maintainability. Other conceptual approaches like the idea of starting from some abstract vision like a (graphical) model (boxes, arrows...); from it, tools generate code skeletons that need to be completed in a subsequent "development" phase. Such "transformational" approaches may even count more than two phases and manipulate different models at different abstraction levels before producing code (this is what I have learned at the university). Such approaches spread the information in several places, because every model or representation has limited expressivity. In my opinion, it produces redundancy and eventually leads to maintenance problems. It violates the DRY principle, which is closely related to our Null-IT principle (see above) On the contrary, gen knows only about code. The "model" you write is a Python package. Being written in a high-level programming language, it does not constrain your expressivity in any way. More important: this code is the running code, and thus the only place where you describe your software. Simply, "wrappers" are added to it in order to plug him into the low-level Zope machinery. A gen-powered Python program acts like a comedian manipulating a tuned marionette: simple moves from the comedian produce complex, cascading and funny behaviours at the puppet level.

quote:

Design patterns are elegant low-level constructs used to overcome the limitations of programming languages (ie statically-typed languages like Java) or frameworks. Using them implies adding classes just for making the plumbery work; it augments code complexity and, again, spreads information at several places. Separating code describing data from code presenting it produces the same problem. appy.gen takes the approach of grouping everything at the same place. For example, information that dictates how a given field will be displayed is part of the field definition.

All-in-one objects.

Just won an old client back, and some old django I worked on about a year has been returned to me for updates, well, in updated form.

The coder they hired was a very special person.

code:

    supplierName_one = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_one = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )
    supplierName_two = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_two = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )
    supplierName_three = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_three = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )
    supplierName_four = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_four = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )
    supplierName_five = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_five = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )
    supplierName_six = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_six = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )
    supplierName_seven = models.CharField(
        max_length=30, null=True, blank=True
    )
    supplierPrice_seven = models.DecimalField(
        max_digits=11, decimal_places=2, default=0,     
    )

...... and so on up to 20

This was latched , along with an incredible amount of other unrelated poo poo on the *User profile* model.

One problem the client has is that when someone else logs on the supplier data isn't there.

And there is so much more of this sort of horseshit. He pulled out all the nato-standard django auth I used and made his own homebaked one that stores all the user data (username/non hashed password/email/etc in profile because "cant find User model" (according to the #comment). And on it goes.

:fuckoff:

I informed the client I'm rolling that poo poo back 6 months and spending the week rewriting it and creating migration scripts to renormalize, resane-ify, and generally unfuck the whole thing.

Its like having my beloved child return after a year on the run and she's now a meth-head pregnant to corrupt cop and a rampant STD infection. Just horrible.

I have to be honest, I was out of the web dev game for so long that I'm scrambling to get back to up to speed for work. At the moment I've got enough on my plate learning AngularJS as well as Single-Page-App architecture and all the craziness that entails (the last time I did any web app development it was still cool to render stuff on the server). I'm just looking for something I can bang on and get an API up and running, so I think I'll roll with Flask and Flask-JWT for right now and look into Django-Rest-Framework later on down the road.

That said, what exactly does a web-facing Python host look like? As in, I'm familiar with the LAMP stack but I'm still not sure how Python and Apache work together to enable me to execute Python like I would PHP. I know that Python's WSGI functionality has something to do with it, and that there's such a thing as a webserver with WSGI support. I just don't know how to build a server that'll play API host with a Python backend. Is Apache still needed if frameworks like Flask can handle HTTP connections? Do I just to expose a port and run Flask on that port?

Its *still* cool to render on the server. The whole serve-a-blob-of-js style of web development is hopelessly misguided in my opinion. Sure google parses javascript these days, but its not that bright about it, and its still going to favor HTML5 over "poo poo all over the browser with javascript".

And yeah AngularJS is insufferable. Check out Ractive, hook it up with JQuery, and it'll do 90% of what you'll want out of Angular, with a half-day learning curve instead of a few weeks of tearing your hair out fighting with Angulars bizzare and opaque ways.

If I never have to develop an "enterprise" Angular app again, I'll be a very happy man.

A class is the constructor or blueprint that is used to create instances that can be edited but the constructor itself is not actually changed in any way, correct?

Not quite but close

Think of it as the difference between a concept and an object. The class *defines* something. The object is an *instance* of it.

Dog is a class. Fido is an object of type Dog.

A constructor is specifically code that runs when the an instance of the class is made. Its a function that sets the new object up. Conversely a destructor pulls it down, but we dont really use destructors in python typically.

I'm in the process of testing something very very awesome. Theres about to be a new sheriff in town for dynamic languages and cross platform mobile dev...

I'll let you all know more when I finish, but my gently caress javascript quest is heading towards glory right now.

edit: BAM

On the simulator it was using the macs system PYTHONPATH. So I threw in a zip of the standard python library into the test suite and passed a PYTHONPATH environment variable in, and it worked. Well, sort of worked.

Remaining tasks:
1) Scour the zip etc for dylibs or .so files to make sure I'm not being apple violating.,
2) If there are any, modify my build chain to statically link them, or if they look apple violating , remove them all together.
3) Integrate this all into QT Designers tool chain.
4) Party. Hard.

None of this is made easier by the fact that QT's brand of C++ is completely perplexing, but I'm getting there.

Its basically importing pyotherside which is a QT binding to python that works with QT5 , and hence works on mobile devices, and isnt PyQt (GPL or $$$$$). The basic difference is, PyQt hosts QT in a python program, pyotherside hosts python in a QML program. There where Android ports and a port to "SailfishOS", whatever that is. But no IOS

So I've been hacking away trying to get it to work on the iphone. I'm basically at the "Hello world" stage of it passing unit tests. Now its just a case of getting it to work with QT Designer projects.

Because gently caress javascript. This is a project fueled by hate. (I've spent the last month staring into the abyss of Angular.JS gently caress.that.poo poo its time for python on the telephone)

Could this also be made to run on Android with NDK? You could have a neat cross-platform kit if you got that figured out, but just getting it working on iOS would be plenty cool all on its own.

I believe it already runs on Android.
