Q: Creating PDF files from a ODT template

The code is actually a TemplateBuilder. We have 2 different templates, French and Dutch. We need to change the template and then convert it to PDF so it can be stored in the DB later. The main method is createBulletins(). What am I looking for? I don't like the constantly reading the template...

Any SQL devs here?

My spidy-senses tell me @Phrancis is one but he isn't here

Our DBA has informed me that making every parameter in a SPROC parameter Nullable is best practice. I'm not sure it is, but I don't know enough SQL to say for sure.

You know what would be cool? using google maps to generate a route for a list of addresses for deliveries, generating a time it will take to get to each delivery, then dispalying that information to people who are expecting a package

instead of telling them to stay within the house between 8am and 9pm

>.>

Zak

You would think it'd be that simple.

And, to be fair it can be (see 1-hour paid for delivery slots)

Dan Pantry

working out an optimised route isn't easy though (travelling salesman)

but it's definitely possible to estimate the time between two points, even based on traffic information

Zak

Unfortunately, for most deliveries, the most efficient overall system works off of the Royal Mail, and, well, they're not exactly at the cutting edge of Technological progress.

Dan Pantry

(Which, regardless of what you think about Google, is pretty frickin amazing)

Zak

9:54 AM

Google has a lot of pretty frickin amazing stuff ^^

Dan Pantry

couple the above thing I mentioned with IoT devices and bam, decent delivery service.

Quill

So I found out today that Google Glass are pretty cheap on ebay

Google totally killed them though

Dan Pantry

Zak

This is also why the only delivery companies that *do* have delivery slots are relatively small/new/specialised. They were built without a legacy system such as Royal Mail to have to deal with.

Hey @DanPantry I'm confused about the usage of Node with Babel

Dan Pantry

@Quill What are you confused about?

Quill

var babel = require("babel-core");
babel.transformFile("script.js", {}, function(err, result){
    result.code;
});

should that return my code?

Dan Pantry

10:51 AM

@Quill why are you using this?

Quill

using what?

Dan Pantry

like, what are you tryign to achieve

babel-core just transpiles es6 into es5

skiwi

@Quill Does that function even return anything? That seems old-style JavaScript to me

Quill

convert some ES6 code I have

Dan Pantry

the callback you've got there is going to give you a Buffer object that contains a string of the transpile code

Quill

10:52 AM

@skiwi part of why I'm confused

Dan Pantry

i don't know what you're doing

which means you probably shouldn't be doing it

are you trying to run ES6 code in Node?

Quill

Yes

Dan Pantry

okay

Quill

doesn't node support es6 anyway?

Dan Pantry

in development, you can use babel-node in place of node to run es6 code

@Quill bits and pieces, not all.

Ideally, what you would do is create a library that contains all of your es6 code

and give it a prepublish script that executes babel on the code

Quill

10:54 AM

right, fair enough

Dan Pantry

then you would use that library via require (i.e, require('my-library')) after npm linking it

in a separate project, that is

and in that separate project, add the binary or executable or whatever

tldr use babel-node unless you're making super serious production apps, it'll confuse you less.

babel-core is for transpiling code from file -> Buffer, it's not for running code

Quill

just setting up a playground

Dan Pantry

npm i babel-node babel-preset-es2015 -g

$ echo "{\"presets\":[\"es2015\"]}" >> ~/.babelrc

(or alternatively put ~/.babelrc in your working directory)

er, if you're using node 5 or up you'll aslo need to npm i babel-core -g

Quill

that first npm command didn't work for me

without babel-preset-es2015

Dan Pantry

@Quill wat

hmm maybe it's because babel isn't meant to be isntalled globally really but locally

in whcih case you're SOL and will have to set up a 'playground' with every project :p

Quill

11:02 AM

npm i babel-node babel-preset-es2015 -g -> not fine, but without babel-preset-es2015 is fine

Dan Pantry

yeah thats because babel-preset-es2015 isn't meant to be installed globally i guess

just install it all locally with --save-dev then

npm i babel-node babel-core babel-preset-es2015 --save-dev ,make sure you're in the correct working dir

Did your DBA give a justification/reason for making all params nullable?

If this code is working then the question probably belongs on codereview.stackexchange.com — Paul R 26 secs ago

Dan Pantry

@Phrancis "it's best practice" and "stops stupid users from calling a procedure"

Phrancis

lol

One thing I try to remember about DBAs is that, generally speaking, they don't know (and sometimes don't care) about business logic very much

Which is fine, that's not their job, mind you

skiwi

The weather over here is really odd... It's like 7 degrees here, but in the northern partof the country people are ice skating on the public roads

Phrancis

Is he suggesting to raise errors each time that a field is null which shouldn't be? Or to swallow exceptions or just return bad data? Or *gasp* send you an email when it happens?

Dan Pantry

@Phrancis no, he is suggesting that we should throw an error if null is passed to a nullable field

instead of, you know, making it non nullable

and SQL will throw the error for us

Phrancis

12:26 PM

Oh, now that's not a bad idea, though it is quite a bit more work for developers

Dan Pantry

it's a terrible idea

Phrancis

It is?

Dan Pantry

there are about 8 parameters that are nullable but are literally always required for that sproc

why would you put in a function descriptor "this is nullable" and then throw a bitchfit if it is ever null

that's like me doing this

void Foo(int? bar)
{
   if(bar == null)
  {
     throw new Error();
   }
}

if it's not optional, don't flag it as nullable, because that's what nullable means - optional :s

Phrancis

Ah. Right.

Dan Pantry

you don't tell someone in a function descriptor "this can be null" and then throw an error every time it is :S

Mast

12:27 PM

@skiwi Yup, a couple of my colleagues didn't make it to work.

Phrancis

From business logic standpoint, yeah I totally see that. It could be that he's more worried about what happens on the back end of the DB

Mast

@DanPantry Sure, it's providing yourself with work.

Dan Pantry

@Phrancis the sql engine would stop you if you tried to call a null value with a non nullable field

there's no data corruption issues to be had here

it's just silly boilerplate

I don't mind if he is a good or a bad DBA - that's my manager's decision to make, nto mine

Just wanted to know if there really was any benefits to taking his approach

From my perspective it literally just seems like he is creating work for himself (or rather, the sql dev who has to code it)

Like @Mast said

Quill

hey @DanPantry what do you think of openshift.redhat.com?

Mast

Winning proposition, as long as you don't get caught. Could cost you your job in the long run if you get caught.

Dan Pantry

@Quill never used it, work wants to start using openstack which I think might be somewhat related to openshift

Quill

it lets me run a free node.js server so I was fine with it

Dan Pantry

It runs web apps for free. Where's the catch?

skiwi

Phrancis

@DanPantry do you have "SQL operator" people that run ad-hoc queries a lot to look into data issues and such?
