Nope, I can later tho
Why?
why, you want an Ubuntu touch Port?
xD
I'm bad at porting tho :/

nocturne galleon
@nocturne galleon well im assuming this is c++, so i give my advice: in ur class definition: ```cpp
class Foo {
private:
std::unique_ptr<int> ptr;
public:
void makePtr(int& number) {
this->ptr = std::make_unique<int>(number);
}
};
@crystal tundra Problem here is that you are creating the pointer already inside the private area. I need a vector<smart_pointer<classnametopointto>> smartpointerlist();. And then I need to be able to fill up that list
crystal tundra
Oh so a vector of smart pointers
nocturne galleon
yeah exactly and the amount of smart pointers inside the vector varies from node to node
Should I just use regular pointers and then do a manual cleanup of the tree?
spring pond
class Foo {
private:
std::vector<std::unique_ptr<int>> ptrVec;
public:
void makePtr(int& number) {
ptrVec.push_back(std::make_unique<int>(number));
}
};
Would this work?
nocturne galleon
How would I adjust it to this one: ```c++
template <typename T>
class smart_pointer
{
private:
T* m_pRawPointer;
public:
smart_pointer(T* pData) : m_pRawPointer(pData) { cout << "node just created" << endl; }
// constructor
~smart_pointer() { cout << "deconstructor for smart pointer called" << endl; delete m_pRawPointer; }
// destructor
T& operator* () const
// dereferencing operator
{
return (m_pRawPointer);
}
T operator-> () const
// member selection operator
{
return m_pRawPointer;
}
};```
@spring pond
some corresponding thing for make_unique
spring pond
why are you making your own smart pointer class
umbral saffron
should I learn java
spring pond
if you don't have a lot of experience with programming its a good place to start
umbral saffron
ok

PyQt5
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QPushButton
these are all the things I imported earlier
it worked before
then I added to it
def QMainWindow
label = QLabel (win)
label.setText ("Attempt one PyQt5")
label.move (50, 50)
b1 = QPushButton(win)
b1.setText ("Click this")
b1.clicked.connect (clicked)```that worked
but ```py
class MyWindow(QMainWindow):
def init(self):
super(MyWindow, self).init()
self.win = QMainWindow ()
self.win.setGeometry (200, 200, 300, 300)
def initUI(self):
self.label = QLabel (win)
self.label.setText ("Attempt one PyQt5")
self.label.move (50, 50)
self.b1 = QPushButton(win)
self.b1.setText ("Click this")
self.b1.clicked.connect (clicked)
def clicked(self):
self.label.setText("you pressed the button")
def clicked():
print("clicked")
def window():
app = QApplication(sys.argv)
win = MyWindow()
win.show()
sys.exit(app.exec_())
window()``` does not
i mean it opens in
but no button
@crystal tundra
crystal tundra
lets just start with some very basic stuff
def QMainWindow
label = QLabel (win)
label.setText ("Attempt one PyQt5")
label.move (50, 50)
b1 = QPushButton(win)
b1.setText ("Click this")
b1.clicked.connect (clicked)```
@umbral saffron this not good code
do not do this
umbral saffron
ok
crystal tundra
but ```py
class MyWindow(QMainWindow):
def init(self):
super(MyWindow, self).init()
self.win = QMainWindow ()
self.win.setGeometry (200, 200, 300, 300)def initUI(self): self.label = QLabel (win) self.label.setText ("Attempt one PyQt5") self.label.move (50, 50) self.b1 = QPushButton(win) self.b1.setText ("Click this") self.b1.clicked.connect (clicked) def clicked(self): self.label.setText("you pressed the button")def clicked():
print("clicked")def window():
app = QApplication(sys.argv)
win = MyWindow()
win.show()
sys.exit(app.exec_())window()``` does not
@umbral saffron this is mostly good
umbral saffron
mostly
crystal tundra
u got the __init__ almost right
however
def __init__(self, *args, **kwargs):
super(MyWindow, self).__init__(*args, **kwargs)
``` should be the first linesecond of all
umbral saffron
so replace that?
umbral saffron
yes
crystal tundra
to add these things
next thing
every QMainWindow needs a central widget
so after ur super function: ```python
self.centralWidget = QWidget()
self.setCentralWidget(self.centralWidget)
next to do
use a layout
look up qt layouts
try use it
make sure to pass its parent as self.centralWidget
and ping me here if u get stuck
umbral saffron
so after ur super function: ```python
self.centralWidget = QWidget()
self.setCentralWidget(self.centralWidget)
@crystal tundra that did not work
crystal tundra
u must ```python
from PyQt5.QtWidgets import QWidget
as well as all the other widgets u r importing
umbral saffron
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QPushButton```i have that
crystal tundra
just put QWidget after
umbral saffron
do i need another one then
crystal tundra
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QPushButton, QWidget```
@umbral saffron
crystal tundra
yeah ik
this is just getting the app properly working
next is
but ```py
class MyWindow(QMainWindow):
def init(self):
super(MyWindow, self).init()
self.win = QMainWindow ()
self.win.setGeometry (200, 200, 300, 300)def initUI(self): self.label = QLabel (win) #look here (change win to self.centralWidget) self.label.setText ("Attempt one PyQt5") self.label.move (50, 50) self.b1 = QPushButton(win) #same here self.b1.setText ("Click this") self.b1.clicked.connect (clicked) def clicked(self): self.label.setText("you pressed the button")def clicked():
print("clicked")def window():
app = QApplication(sys.argv)
win = MyWindow()
win.show()
sys.exit(app.exec_())window()``` does not
@umbral saffron
as well as that
clicked should be a member function
indent it properly
and do self.b1.clicked.connect(self.clicked)
umbral saffron
in replacement of self.b1.clicked.connect (clicked) right?
crystal tundra
yup
just remember
self.
for any member variables
u have to specify self
i.e. self.win not win
crystal tundra
yep
so self.b1 = QPushButton(self.centralWidget)
instead of self.b1 = QPushButton(win)
umbral saffron
so for every thing u need to import them
wait wait wait
i got it
i just need a way to call initUI
right?
actually just all of MyWindow
i might be wrong
spring cove
might i ask, im new to programming, what language is that?
umbral saffron
Python
spring cove
oh ok cool
umbral saffron
im still learning it too
spring cove
ok thats all i had to ask, good luck with that project or whatever it may be
umbral saffron
thanks

Hey guys, I need a bit of direction in this python project I'm working on.
I found this JavaScript library that I could use for my project. But I don't know JavaScript and I don't find an equivalent python library.
Is there any way I can use the JS library in my python project?
steel ether
How?
I don't think speed is going to be an issue here.
It's just a basic prototype so far.

Hey guys someone can help me with phpmyadmin?
For some reason it stopped working.
I can't do anything inside it.
When I try to click something there it just refresh the page.
rotund plover
I'm using phpmyadmin only for viewing
warm sleet
phpmyadmin not really the best solution for managing an sql database
warm sleet
@rotund plover workbench can directly connect to the sql server
so you dont need php, or phpmyadmin
rotund plover
Is there a good workbench for Linux ?
warm sleet
it runs on linux too
rotund plover
Except terminal
warm sleet
Its a desktop program
@rotund plover it has a table inspector, database inspector, as well as the regular tree-view on the left side like in phpmyadmin
rotund plover
Now works except viewing tables
warm sleet
SELECT * FROM table
rotund plover
I hate php
warm sleet
That's not PHP, but SQL
rotund plover
Ya
I never had a great time with phpmyadmin
Not even good time
Always had problems
warm sleet
phpmyadmin is commonly used by those 'managed website' hosting
where you get FTP, and phpmyadmin to manage everything
rotund plover
Yes like cpanels directadmin and etc
warm sleet
cpanel is a bit more
rotund plover
I hate it
warm sleet
phpmyadmin is specific to webapplication hosting with php
rotund plover
Ya
warm sleet
SQL development I do from within my IDE
viewing, migrating and managing databases I do with the workbench
warm sleet
That SQL Workbench has a built in ssh client, so you can use it as a proxy
so you can tunnel sql over ssh
over a firewall
most sql servers only accept connections from localhost
rotund plover
Ya but I have private IP at home
warm sleet
rotund plover
So I can use it Normally

rotund plover
And 120
rotund plover
No just saves cache and logs in db
Not something important
I wondered what will happen if I remove all of it without the customer permission
Didn't went well
rotund plover
But I was able to blame his programmer because he already fucked up the vps disk
warm sleet
compress the file and scp it to another machine
rotund plover
Replication of 120gb db to another server in another DC out of my country
When my country doesn't have good internet to outside of the country here
warm sleet
sounds like you need fiber
rotund plover
Fiber will not help to
warm sleet
I got a 1G x-connect to my VPS in the datacenter :)
warm sleet
Nah, I ment as in. My home internet has 1G to the VPS, and 250M to the wider internet
rotund plover
Ya
warm sleet
never again.
rotund plover
Our ISPs here don't want to be connected to each other directly and lower out latency and ms to each ISP here
rotund plover
Each company connect only them self's
warm sleet
they don't peer among eachother?
rotund plover
And building not private houses so I'm fucked up
they don't peer among eachother?
@warm sleet nope
I can ping my friend IP and get like 40ms
warm sleet
yeah but adsl already has poor latency
rotund plover
Even the fiber not peered
My friend have it he pinged someone that in different ISP he got like 45ms
hollow basalt
rotund plover
The ISP told him that because he is too far from their rack thats why he get such high ping
All the ISPs here togther if they'll be connected to each other will have max of 2tb bandwidth
hollow basalt
hmm private peering is expensive
warm sleet
Not sure you understand what peering is
rotund plover
Fortnite updates crashed all the outbound traffic 2.5 weeks ago
warm sleet
hollow basalt
Not sure you understand what peering is
rotund plover
We had no access to facebook youtube google play store apple store and all the services that not hosting in my country
1 day
hollow basalt
and you expect peering to solve that?
rotund plover
No I except they will be able to handle it
warm sleet
We had no access to facebook youtube google play store apple store and all the services that not hosting in my country
@rotund plover sounds like time for a holiday
hollow basalt
rotund plover
We had internet only to services that hosted here
rotund plover
My dedicated server hosted in Germany and this hosting provider have more than 5TB of peering
warm sleet
thats not peering
rotund plover
They are connected all over europe I wish our ISPs here will do that
warm sleet
Thats just a traffic allowance
midnight wind
but that's not what peering is...
rotund plover
They are not peered to anything
That's not really meters
We want low latency with fiber 40ms inside the country is fucking high
rotund plover
I'm talking about latency not peering now
I know that is peering I just not talking about it right now
They are connected to IIX but still shit.
The ISPs here are not good enough
Wanna hear something funny
My ISP said it's ok to get 600ms to their gateway
warm sleet
get different isp 
rotund plover
All of them like this here
I have 3 fibers under my house 🏡 and none of those ISPs willing to connect me
Oh ya after they said that the started to blame my hardware
gusty girder
When creating a resource using a REST api, should I only reply with a 201 Created, or should I also show the created data?
vs
shy helm
You should return the created resource
Is there a reason why you’re building a “response” object? All that data should just be in the HTTP response header, no need to add it to the body
spring pond
^
Most if not all of the response object is unneeded. You could maybe use the message string, but it is probably unnecessary
actually im 99% sure that you will not need it because you shouldnt be rendering a response directly
warm sleet
@gusty girder depends. what kind of API style you are using.
pure REST always expects you to return the content you sent
except POST
if you create a new item with PUT you should return the object.
This is useful for things like generated primary keys (by the database)
@shy helm not nessesarily.
you can have things like "_status": "201 Created" in the top
shy helm
I mean sure, but there's really no point
shy helm
ehhhh
I'm not a big fan of custom headers, too much tie in
If you can't return the data you need in the body or in standard HTML headers, you're doin something odd
warm sleet
Auth is the only place I use it strictly
warm sleet
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://localhost:8090/;
proxy_redirect http://localhost:8090/ http://$server_name/nexus/;
}
Nginx <3
@shy helm in my application APIs I embed exceptions into API responses
when the API returns a non 200 code, the client unmarshalls the exception (instead of the expected object) and throws it
private static T Deserialize<T>(string data) {
try {
var serializer = new XmlSerializer(typeof(T));
using (var reader = new StringReader(data)) {
return (T) serializer.Deserialize(reader);
}
} catch (TargetInvocationException) {
try {
var serializer = new XmlSerializer(typeof(ApiError));
using (var reader = new StringReader(data)) {
throw new ApiException((ApiError) serializer.Deserialize(reader));
}
} catch (InvalidOperationException) {
throw new ApiException(new ApiError {code = -1, message = "Unknown Error", status = ""});
}
}
}
You use XML responses o.O
warm sleet
I love xml
shy helm
pain
warm sleet
@shy helm I will use json when they finally standardize a schema
all the types the API provides I export as xsd
The actual client is an interface facade implemented with rest
the java server interfaces are identical to the C# client interfaces
shy helm
There's a bunch of standards for JSON schemas
warm sleet
I've yet to find one that can generate it from java source files
the REST interface itself can speak both XML and JSON
But I choose the use XML, its just easier to do with .NET
warm sleet
Cool
I've been looking for a way to improve on this
I'm using a deprecated java tool to do this
JXC was removed in java 10
shy helm
TBH though, most people are moving towards doing it the opposite way
schema -> code gen for classes
warm sleet
I'm aware
shy helm
Protobuf, Apache Avro, etc
warm sleet
this workflow kinda grew out of a pure java environment
shy helm
I'm a big fan of protobuf tbh
warm sleet
@shy helm https://i.imgur.com/JcarbHK.png
shy helm
great performance, small message size
If you want to do pure Java then why do you need to export schema?
Just use GSON and annotate your class, move classes to a shared lib
warm sleet
EclipseLink
w/e, they just offer a way to use the XML APIs from java
to do json as well
shy helm
I'm just bugging you 😛
warm sleet
Code first
I know schema first is the new hotness
those objects are modelled after what comes out of the database
shy helm
It's the new hotness because schema registries are becoming hot
tbh though, I don't hate it, very useful when doing large distributed projects
good way to do schema/interface evolution
warm sleet
@shy helm GSON fails for me
when I try to do things like lists
@Data
@NoArgsConstructor
@AllArgsConstructor
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "Profile")
@XmlType(name = "Profile")
public final class Profile implements Serializable {
private Player Player;
private Highscore Highscore;
@XmlElementWrapper(name = "Spells")
private List<Spell> Spells;
private boolean Online;
private Family Family;
}
Why does it fail for lists?
warm sleet
long time ago, but I always had issues with the annotations it provides
And the beauty of using JavaEE interfaces, is you do not need any additional dependencies to use
though.. that holds true for GSON, annotations are not required runtime
shy helm
hmmm, idk I haven't experienced these issues, couple of years ago I worked on a big big rest API for a very popular mobile app, we used GSON extensively
was a Spring Boot app though so 😛
warm sleet
@shy helm MOXy also ties into the JAXBContext
and the rest server I use, Jersey, can use it too
@shy helm this is pretty much all JavaEE
@GET
@Path("{id}")
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
@Override
public Player getPlayer(@PathParam("id") String uuidString) {
UUID uuid = parseUUID(uuidString);
PlayerDao dao = provider.getDao(PlayerDao.class);
Player player = dao.getPlayer(uuid);
if (player == null)
throw new NotFoundException("No player with that UUID was found");
return player;
}
sorry for the many pings
bad habbit from IRC
shy helm
heh no worries I do it too
warm sleet
You could do rest applications without any of this nonsense
If you just write JavaEE provider classes
you can use an Appserver like Tomcat
to provide all of this crap for you
shy helm
heh yeah, there's tons of ways to skin the cat
warm sleet
@shy helm this just gets called by maven during the package step
but oracle been cleaning up the tools.jar
gusty girder
@warm sleet thanks
warm sleet
@gusty girder forgot to mention
Look up 'rest idempotency'
An idempotent HTTP method is an HTTP method that can be called many times without different outcomes. It would not matter if the method is called only once, or ten times over. The result should be the same.
Idempotence essentially means that the result of a successfully performed request is independent of the number of times it is executed. For example, in arithmetic, adding zero to a number is an idempotent operation.
POST to create new content, PUT to update existing content

@rotund plover workbench can directly connect to the sql server
@warm sleet
I have problem with this bench.
I can't view inside the tables
warm sleet
@rotund plover what user account are you using to log in ?
need to have the right permissions to view info schema
silver furnace
You can set perms on the info schema I think
Never apt mysql from current ubuntu sources.
midnight wind
why, are they outdated?
silver furnace
It won't even use password auth. Uses something otherworldly. You won't even be able to login with -u -p unless you kill the service; start it up manually with some flag to ignore auths. Then you get in as root only to find out that you don't own the schema with users
Turns out you gotta flip the auth module and even then, it autogenerates a password for a real "root" user called debian-sys-maint
I guess this is the Debian distrib for 8.x; not just Ubuntu
why, are they outdated?
@midnight wind Nah, too updated for my taste
midnight wind
ah ok
silver furnace
It's ok, though. 5.6 is manually installed through deb packages anyways 🤷♂️
MySQL 8. What is MySQL 8? Never heard of him
You run the darn thing under a separate user, allow only local connections, who even needs a password. If there are multiple apps that shouldn't access eachothers' dbs, you can use something other than root
(The joke being <=5.6 because I would only use MySQL for legacy/compat reasons)
rotund plover
MySQL 8 is the newest MySQL engine that got released recently.
But I still prefer Mariadb.
hollow basalt
I mean, they should be compatible
rotund plover
Ya
I just don't know why MySQL workbench not working as it should on fedora after connecting my server
This is the error
I'm using root
From my phone it's working perfect
Only MySQL workbench gives it
silver furnace
your select or update clusterfking of columns
fff
You need brackets
Nope not it either
I think it's backtick instead of quote
Or you're running just the single line instead of the whole script if you define the global var earlier
warm sleet
@rotund plover what sql server version are you running
@silver furnace this the schema inspector of the mysql workbench
it fires off a big query to fetch context information
rotund plover
It's pretty the same and it's fucking dumb if it's not working with mariadb
warm sleet
newer versions of mariadb are not compatible with the workbench
rotund plover
Ah
warm sleet
SQL queries themselves will fire properly
rotund plover
Well fuck it
warm sleet
but database context that the workbench uses will fail
THat's another client that works relatively well^
rotund plover
I guess the update for mariadb fucked something
warm sleet
@rotund plover nah the server is fine
MySQL Workbench is only officially supported for MySQL
not for MariaDB
rotund plover
That's why phpmyadmin got broken I think
I did update to the server

if you want you can store it in a string then yeet that string into your html

Well if I change the for files in files in template to , for file in files I get output
But all duplicated
All the first and second rows
hollow basalt
can you show us
rotund plover
Ya you can surf to my website in 10 second and see it under gallery
Oh wait
Stoped working completely
Now you can see it
All row 2 duplicated all over the page
Any ideas ?
hollow basalt
I can only see banana10
rotund plover
Ya
That's the problem
This is only row number 2 from the table
If I change 1 letter you'll see only the numbers again
I can send you the original code
Before I tried to implement it to my site
I changed it to MySQL and implemented it to my site
At least my login and register works perfect

For anyone that has experience with linked lists in c++; If I want to access the 5th node in a linked list do I need to traverse the previous 4 nodes before accessing the 5th node?
vestal glen
That's how the data structure would work, yes.
queen zenith
these data structures are blowing my mind. I never thought trying to figure out the best way to store/search data would be this interesting.
I just looked up hash tables. You turn what you want to store into an index which determines where its stored in the array so you can access it immediately without searching. THATS SO FREAKING COOL
lone cairn
So, I'm learning python and I'm trying to create a simple program that accesses a local db, reads a csv, writes the contents to a table (id, firstname, lastname, email, password), then run a query that can fetch the id/password and then hash the passwords.
The literature reading is not going well for me and I don't know where the ideal resources for figuring this out might be, lol.
hollow basalt
Sure
My suggestion is:
- Find a library to read csv
- Find driver for database, is it mysql/mariadb ? Postgre?
- Hash the password when saving to database, not when fetching it
lone cairn
mysql, and I have been able to figure out a method that should work, but now weird errors galore, lol.
using a dictionary approach to input the contents of the table,; however now my program in the middle of it gets a "mysql" not defined.
I imported like this at the top, was I incorrect?
import mysql.connector as MySQL
from mysql.connector import errorcode
import os
from csv import reader, writer
import random
import time
from passlib.hash import argon2
import csv

"'firstname' varchar(45) NOT NULL,"
"'lastname' varchar(45) NOT NULL,"
"'email' varchar(45) NOT NULL,"
"'password' varchar(22) NOT NULL,"
"PRIMARY KEY ('ID')"
") ENGINT=InnoDB")
for table_name in TABLES:
table_description = TABLES[table_name]
try:
print("creating table{}: ".format(table_name), end='')
cur.execute(table_description)
except mysql.connector.errors as err:
if err.errno == errorcode.ER_TABLE_EXISTS_ERROR:
print("Exists currently")
else:
print(err.msg)
else:
print("OK")
#infile
infilecomp = open("data.csv")
csvReader = reader(infilecomp)
#next(csvReader)
#print
print("moving along...")
for row in csvReader:
try:
cur.execute("INSERT INTO users VALUES (%s, %s, %s, %s, %s)",
[row[0],row[1],row[2],row[3],row[4]])
conn.commit()

@lone cairn so in your case, instead of making a current copy, you would just make a new branch and once it works, you would merge it into master.

Hiya. Anybody around to answer a simple question?
hollow basalt
depends
ruby pewter
Basically
I have a very very very long line with a ton of code. Is there any tool online that'll separate each tag into a different line?
Like say I have: <div class="w-full sm:w-1/2 p-6"><div class="w-full sm:w-1/2 p-6"><div class="w-full sm:w-1/2 p-6">
Instead of it being in a line, I'd get an output with each of those in a diff line
I kinda did it with find n' replace using VSCode but I'd figured there's a tool that'll make that easily.

Is it dumb to call a function with the name of the class the function belongs to every time like: ClassName::FunctionName(). Or is it good coding practise
because my code ends up looking pretty messy with all the ClassName::
if (Rules::IsItOutOfBoard(MoveFormatting::oldx(BoardClass::ScanGetCordinatesW(x + counter, y)), MoveFormatting::oldy(BoardClass::ScanGetCordinatesW(x + counter, y))))
I'd say the lack of line breaks is worse for readability than the class names.

so I have an HTML question. How do you align the text in the center(in a table) in HTML but without it looking like a pyramid or something. I mean it's cool but I want to align the first row in the center and then every other under it. If I do align=center it just goes center for every text so it becomes like a pyramid
How can I align it in the center but like every text begins where the previous one does,without an indent?
bleak breach
@tired juniper got a photo of what you’re going for?
warm sleet
@tired juniper You're looking for CSS here, not HTML
align is a style
Though there are elements you can use for 0-width and merging cells
its the colspan property of a table cell
You will ultimately have to make a grid
like a 9x9 grid, and use colspan to merge cells
though using tables for alignment is a kind of dirty solution. div's are your friend

Android, for android 8.1 and up

If I've googled correctly you'll need to develop an android app that requests the android.permission.USAGE_ACCESS_SETTINGS permission.
Here's a tutorial to get you started: https://www.youtube.com/watch?v=Ob4vSoWud9k

Thanks! Probably waited to long to start with this project. I have to finish it by the 8th of January

@outer fjord Code Academy has good tutorial on android
assuming you already know java, it has some good explanations on how android activities work
It also assumes you use Android Studio ofc
outer fjord
Yeah I'm gonna use Android Studio, but I'm new to coding, I know a bit of PHP but that is about it. Luckily my partner knows a lot more about coding
warm sleet
@outer fjord Android has a bit of a confusing API
the idea is you have an Activity, with elements you define in an xml file
you can then use code in the activity to make it do things, all elements you put on screen like a button, text input etc, are configured in the xml layout
Android has some good documentation on how this all works
outer fjord
I'm gonna look up some guides to get a basic understanding
spring pond
if you want to try something more modern you could try jetpack compose https://developer.android.com/jetpack/compose
its still in development tho
outer fjord
so what are the benefits of Jetpack compose compared to Android Studio?
warm sleet
jetpack is just a framework to design apps with
outer fjord
Oh okay
warm sleet
It also uses kotlin instead of java
nothing wrong with that, Kotlin is a fine language
Compose is just nice if you want rich media applications
with lots of visual flare
Android window (activity) kit is a bit crude at times
spring pond
i believe that jetpack compose is just a declarative version of the android ui builder
warm sleet
yea
spring pond
it looks really similar to swiftui
outer fjord
Oh yeah, I'm gonna follow a basic guide so I get an understanding of Android Studio
spring pond
you definitely want to do that first
warm sleet
@outer fjord do you have a phone to test with?
If you enable developer mode, you can link it up with Android Studio
and run the app on the phone, debug on the computer

and all the JavaEE interfaces don't exist on android
Not that you need them necessarily
but makes life easier
spring pond
what does java ee do? is it just a bunch of language extensions?
warm sleet
@spring pond JavaEE is just interfaces
spring pond
huh
warm sleet
they define a common interface between the application and the application server
warm sleet
the idea is that things like databases, rest services and all that crap, is not handled in user code
but by the application server instead
so you just request an instance of an interface, and dont care how it gets created
spring pond
ok
spring pond
im probably just gonna try to learn kotlin for android and hope it goes well
from what ive done before its quite similar to swift so thats nice
warm sleet
@spring pond the benefit of JavaEE is that everyone uses it
so any library that has to work with enterprise stuff, uses JavaEE
and you need less glue code
Inversion of control serves the following design purposes:
To decouple the execution of a task from implementation.
To focus a module on the task it is designed for.
To free modules from assumptions about how other systems do what they do and instead rely on contracts.
To prevent side effects when replacing a module.
considering your comment that the code is "not in user code" does that mean that ee is server-side only?
spring pond
ah ok
warm sleet
If you develop servlets, you just ask for database access
and the servlet host, Tomcat, Glassfish, or whatever, has implementations for that

Could someone here help me with java ?

ye
wind oracle
alright I need to sort a int[] that's full of numbers from smallest to biggest
using a for loop and positions
spring pond
well you could just use a sorting algo
wind oracle
public static void intExchange(int[] table, int pos1, int pos2)
thats all he gave us
wind oracle
positions
spring pond
but what are you supposed to do with them? are they meant to represent the bounds of a subarray or what
wind oracle
huh the positions of the smallest ones I think
spring pond
are you supposed to swap pos1 and pos2 in the array? thats what would make the most sense with the header
wind oracle
I think im supposed to out print
here's what I have
it just out prints the list of "players"
spring pond
so do you want to sort the players based on an attribute?
spring pond
i'm not sure how far along you are in cs, but i'd strongly recommend making an object out of all of these players
wind oracle
how can I do that
wind oracle
huh yea
nomJoueur = playerName
pJoue gamesPlayed
nbBut ammountGoals
nbPasse ammountPasses
points = points
minuteP = minutesPlayed
spring pond
ok, working on it
@wind oracle
class Player {
private String name;
private int gamesPlayed, goals, passes, points;
private long minutesPlayed;
Player(String name, int gamesPlayed, int goals, int passes, int points, long minutesPlayed) {
this.name = name;
this.gamesPlayed = gamesPlayed;
this.goals = goals;
this.passes = passes;
this.points = points;
this.minutesPlayed = minutesPlayed;
}
public String toString() {
return padLeft(name + " " + gamesPlayed + " " + goals + " " + passes + " " + points + " " + minutesPlayed, 35);
}
public String padLeft(String s, int n) {
return String.format("%" + n + "s", s);
}
}
now you can turn your old arrays into an array of objects and then use a sorting algo to sort by goals
warm sleet
@wind oracle you can use objects to group data together
and have them represent some concept
like a Player has properties such as name and gamesPlayed
so given the code that @spring pond posted
you can do things like:
Player[] players = { new Player("name", 1, etc), new Player("name2", 2, etc) }
but at this point, I would recommend using lists, its much easier
List<Player> players = new ArrayList<>()
you can then players.add(new Player(...));
Arrays cannot change in size, but Lists can
