nocturne crypt
it just sounds like you're using the wrong tools
python and java are very opinionated about what tools you should use
i like looking at C++ the same way people look at mikrotik stuff
shy helm
C++ just has terrible dependency management, it's not a hidden secret
shy helm
One of my ex-teammates (when I worked with C++ professionally) is in even a SIG for this reason...
nocturne crypt
okay, well. if you create crazy dependency hiercachies then you'll have a bad time
but if you just add simple restraints it becomes much easier
shy helm
Do you work in a professional environment with C++? 😛
nocturne crypt
lol yes
lone cairn
I'm learning sql and need to find an address in a mock database that is associated with any ip address that has 100 in the beginning; I'm not sure if I can post code here, so I was hoping someone could redirect me to where I could inquire about this
shy helm
How do you guys manage it?
nocturne crypt
it depends on the project
shy helm
How do you guys distribute your C++ package updates? DPKG?
nocturne crypt
if it's not an accelerated workload we can just spin up a bunch of code-server instances and automate the depencies installation with terraform
if it requires bare metal access then we just spin up a local git repo that mirrors the dependencies. no wild git repos are allowed
if you're talking about how the application gets distributed, most of the time it's just a single binary
this is the appeal of go, right? you just shove a signle binary image in a docker image and deploy
now if you're asking in your context of how you deploy a C++ application with dynamic dependencies as a web service
shy helm
heh yeah I guess that is part of the appeal
nocturne crypt
you just use docker
shy helm
True, if you can create docker containers for your apps than I guess it's far easier
shy helm
Does the git mirroring just mirror them to a custom directory, and then you have custom build tools that auto map?
nocturne crypt
we use a gitea instance to basically have a local github repo
shy helm
Sure, but when you're linking how does your compiler find them?
nocturne crypt
most of the time they're header only libs
shy helm
o.o your entire codebase is header only?
nocturne crypt
99% of it
shy helm
wild
nocturne crypt
if a dynamic library is needed for a specific reason
shy helm
Ok yeah that makes life far easier
shy helm
the company I worked at is one of the few, big, tech companies that's been around for more than a few decades
nocturne crypt
simdjson is probably one of the few things that actually need to be compiled into a lib
shy helm
packages were distributed using DPKG to baremetal, both linux and solaris systems
very little containerized workloads, for performance and reliability reasons
nocturne crypt
solaris makes everything complicated
shy helm
packages had to be static, if not header only
nocturne crypt
yea honestly dynamic libs are cool
shy helm
we're also one of the few tech companies that have our own version of STL
shy helm
both, all custom
nocturne crypt
fun times
shy helm
yeppp
nocturne crypt
nooooo
shy helm
major contributor to the CPP standards, so we're ahead of the times sometimes
but other-times it's like... why does this not exist internally? And the response is "Well, we didn't agree with the committee on this, so we didn't make it internally"
nocturne crypt
so did yall make the leap to adopt some of the parallel stuff from khronos yet?
shy helm
heh, not sure, I don't work with the C++ stuff atm 😛
nocturne crypt
there's a huge push to put general compute in the API layer now
like for agnostic OpenCL, Cuda etc
shy helm
But if you ever come across polymorphic memory allocators, you can ~curse~ thank us for that
😛
shy helm
Oh, well, you're welcome!
just make sure you don't orphan your object when you return it 😆
nocturne crypt
i've got sanitizer checks to yell at me
shy helm
Still though, gotta say Java (what I mainly use now) does have far better dependency management though
nocturne crypt
if you try to wild wild west C++, it can end really badly
shy helm
It's just so much easier uploading to artifactory and pull automatically
nocturne crypt
the same way if you copy paste routerOS configs from the internet into your deployment
that too will end badly
shy helm
true
nocturne crypt
CI/CD with k8s is so fun
did you see the new Rancher 2.5 additions?
to make it even easier?
shy helm
but as a dev, it's not worth my time fighting to deal with packaging and dependency stuff
and the setup time for java projects is just so much lower
nocturne crypt
it's just the familarity with the tooling
if you like java more
then you probably understand the tooling a lot more
the problem is C++ isn't opinionated at all
so when people look up tutorials
shy helm
True, the C++ build tools do have a steep learning curve, but even being well versed with cmake, I can't say it holds a candle to Gradle
nocturne crypt
they get question marks flying over their heads
like the C++ modo is just defer until you can't anymore
shy helm
Also, C++ does itself no favours with shit errors
Which thankfully I believe they've fixed now?
nocturne crypt
C++20 with concepts fixed that
shy helm
specifically template errors
nocturne crypt
it's now about failing to meet a concept
instead of syntax failure
syntax failure errors are in fact garbage^garbage
shy helm
I do have to catch up on C++20, we were still on C++11/14 when I last worked on it
(partially because... Solaris)
nocturne crypt
this is why you hate C++
shy helm
LOL fair
nocturne crypt
wait until you find out what they're doing
like C++23 is basically going to have a contexpr JIT for compile time nonsense
also non-integral value types for C++ templates
gcc10 already has it for strings
shy helm
I really want an update to C++ Programming Language
nocturne crypt
like if you want blah<"abcd"> my blah;
shy helm
but Stroustrup seems to have no interest
nocturne crypt
lol bjarne?
shy helm
yeah
nocturne crypt
do you mean his books?
shy helm
Yessir
nocturne crypt
i mean if you've ever talked to him
he feels out of depth in C++
the community took it way to far lol
shy helm
Ah
nocturne crypt
the books he published are and were for foundational knowledge
nocturne crypt
they are really good
shy helm
Have any other recommendations for C++17/20?
nocturne crypt
i'm flipping through my personal library to see
honestly CppCon videos are a really good first start
shy helm
True
shy helm
heh, always fun to play with
nocturne crypt
https://www.youtube.com/user/lefticus1, he's legit a master at explaining C++
kate gregory usually maintains a list of educational materials
lol containers in FreeBSD
jails are the fastest way to find a noose
he has a video that explains pmr
shy helm
I'll check it out 🙂
nocturne crypt
if you have any questions feel free to ask
honestly most people ask for video tutorials and I learned by reading the actual standard props
i'll ask around about a good book
shy helm
I prefer reading technical literature on stuff tbf
video tutorials drag on too much lol
Maybe I'll just read the standard docs
nocturne crypt
yea the standardization papers are well written, I agree the videos drag on lol

vital blaze
The best part is the dependencies 😆
left drum
hmm how is javascript less of a language than any other language. If you write crap javascript, you will get crap javascript. Same as any other language.
Most problems i feel come when people try to write javascript like it was java or c#. Also problems start to arise when you use vanilla javascript to build huge applications without a well thought out design pattern in mind. That or some framework.

@left drum I'm trying to use typescript
and even that is full of weird problems

cyan dagger
@warm sleet I havent subjected myself to that confustion yet, I always get issues on github repos about it and just say we dont support it so it would be good to look into
warm sleet
yeah but all these weblanguages are awful
default tools like npm are total crap
build structure and project lifecycle management requires you to write your own code
cyan dagger
I have stuggled with the js eco system over anything else even with 5+ years of programming
warm sleet
and every project
has their own special sauce
everyone exposes their api differently
sometimes you end up with stupid callbacks, when you don't need one
which ends up making incredibly unreadable code
cyan dagger
callbacks are hell dont get me started, i try to stick to async and await
warm sleet
typescript has that embedded in the language
its slightly less painful
I'm developing a framework right now for a headless CMS
cyan dagger
when i have a free couple of hours i will have to have a look into it
warm sleet
using typescript, and graphql
cus graphql can do schema exports
something that previously was only possible with xml rest
so I can generate an MVC environment around express and hook into the cms
generate classes from it
I've written many frameworks in java
this is first time in js
and its killing me
cyan dagger
graphql is really interesting to me, iv only used it when querying the github api
im coming from swift and js is definetly really different
warm sleet
graphql behaves like a graph lol
There's other platforms that have similair structures

@hollow basalt even so, these RIAA people have got little to stand on
I can use youtube-dl to download my own content

I've received DMCA takedowns before

hollow basalt
The more DMCA I see, the more I get the urge to help these tools
it is counter intuitive for them
thanks for brigning youtube-dl to the spotlight
vestal glen
Even if they clean up the source code to no longer "suggest" illegal actions, I wonder if they'll have to change the project name, since they're currently using the youtube brand name, which youtube may not be a fan of due to wanting to be on good terms with the music industry?
hollow basalt

@warm sleet these US laws that think they own the world

@vestal glen then it's google's mercy not the music industry
warm sleet
@vestal glen its not yt filing the takedown
its an agency on behalf of Sony, Warner and the likes
so the usual scum

@warm sleet yes, but what I'm saying is that the sony warner and the likes may go to yt and ask them to please stomp it. And yt just may since it's technically against their dev agreement too etc.

if you torrent illegal material, sure, its illegal
but torrents themselves arent illegal.
hollow basalt
With that logic, chrome and firefox is illegal cause you could download illegal materials
warm sleet

frozen pulsar
well yeah. If you download the whole The Walking Dead from TPB then it's illegal
warm sleet
yes
but these lawyers put the owners of the tpb in jail
and charged them for damages in the orders of multiple millions
even though, they never spread any illegal content.
frozen pulsar
So I can have a site like TPB and not go in jail? 🤔
hollow basalt
TPB is just an index
warm sleet
they actually went after them, for the tracker.
but now, the piratebay doesnt use a tracker anymore
hollow basalt
With logic, they should jail google cause you could easily find pirate websites
warm sleet
they use DHT, which is completely decentralized
hollow basalt
but now, the piratebay doesnt use a tracker anymore
all hail DHT
frozen pulsar
DHT?? :https://prnt.sc/v5w6lg
hollow basalt
Yes
hollow basalt
so they just try to attack the index
warm sleet
and the hash can be used to resolve the torrent peers from the network
no central server is needed.
so there's no head to cut off.
warm sleet
and piratebay was raided like 5-6x

I compare to java quite often
icy wagon
It couldn’t have said unlike every other programming language
warm sleet
@icy wagon Lua does this too
icy wagon
Yea but lua is lua
warm sleet
matlab is for mathematicians who suck at coding
those who grow a clue, tend to drift towards python
icy wagon
But only python?
icy wagon
warm sleet
which are very commonly used by people who run compute
icy wagon
I see
warm sleet
scipy's library implementation is natively optimized
so even though your logic is in python, the calculations themselves are with library functions, and thus run well optmized
I've used numpy https://numpy.org/
for importing and processing data from CSV
warm sleet
and matplotlib to render graphs with it
icy wagon
I still don’t understand the point of dynamic typing
warm sleet
You mean ducktyping languages like Python, Lua and PHP ?
icy wagon
Sure
warm sleet
Less boilerplate
hollow basalt
Python is really powerful
It's like matlab
But sane
That's why Jupytwr notebook is soaring
warm sleet
Python has well established standards of "how we do things"
it delivers out of the box libraries to build webapplications, desktop applications, as well as data systems and multimedia
hollow basalt
Python is the embodiment of DRY principle
warm sleet
@icy wagon for simple systems, the hastle is having to define types and structures for everything
in languages like java, you need a lot of glue code to make two things work together
patterns like 'adapter' are not needed in python
warm sleet
since adapters are typical in contexts where type safety is a requirement
@hollow basalt I actually prefer statically typed, for many many reasons
the primary being: less mistakes
icy wagon
What
hollow basalt
Then use python with static typing
icy wagon
Typing int String long is more work?
warm sleet
C# has var for variables you define & instantiate
var foo = "a String";
java however, does not have this
icy wagon
kotlin if you really wanted
cinder kraken
var in c# is so damn handy
icy wagon
I guess it doesn’t matter in small projects
warm sleet
If I am developing for the JVM, kotlin is too much hastle
I might as well just write java straight up
icy wagon
But in large projects it seems really annoying
hollow basalt
If I am developing for JVM, I should be questioning myself
warm sleet
Kotlin is great for android
hollow basalt
Kotlin is only viable for intellij ide
warm sleet
Because kotlin has features that are unavailable in java 7
things like lambdas and string interpolation are built into kotlin
icy wagon
Why use java 7
warm sleet
because android uses java 7
icy wagon
Bruh
warm sleet
Its just the language version, not all of java
hollow basalt
Didn't they upgraded the java runtime
Java7 is dalvik
Didn't they upgraded it when they moved to art
warm sleet
Not all of the java 8 features made it into android studio
@hollow basalt ART still runs dalvik
its just that the JIT compilation is done ahead of time
icy wagon
Large projects with dynamic typing seem like a hassle I should say
warm sleet
@icy wagon even dynamically typed languages support some form of type awareness
hollow basalt
I mean yea dalvik, but I consider it anew
warm sleet
like in PHP, IDEs can look at the comments above the method call
icy wagon
Well just for keeping things organized and readable
warm sleet

imagine comparing things to java
@hollow basalt The reason is it's comparing to java is that it's from a slide from a course for math majors at my school. The math students have to take 2 intro to CS courses wich up untill this year was taught in java.
icy wagon
What do they teach now
vital blaze
The intro courses are now in python though.
icy wagon
Oh
warm sleet
my school taught me how to write broken PHP
icy wagon
Honestly they should start with c++
hollow basalt
vital blaze
my school taught me how to write broken PHP
@warm sleet That's our webdev course.
warm sleet
yes
icy wagon
Ah
vital blaze
they should start with pure C
@warm sleet That's os with this man
warm sleet
but in the sense that you might think
hollow basalt
C got updated, it's called c++
warm sleet
C allows you to really understand what the computer is doing
icy wagon
Yea
warm sleet
this teaches you structured programming
the stack, the heap, method calls, variables
references vs values
The step up after structured programming
could be OO concepts
icy wagon
Going from js or python to c sounds like it would be hard
vital blaze
Java is much cleaner when it comes to learning OO
@warm sleet I agree
warm sleet
honestly, touch of C and Java
helps people self develop C++ if they ever need it
plus, these are languages you may actually be able to use yourself
C is great for learning how to do stuff on arduino
vital blaze
I think what my school is doing first year python, second and on java for the main courses. And other languages if it's better for the specific course(ex c for os)
warm sleet
and Java can help you develop something alongside, on a PC
icy wagon
make an os
hollow basalt
That's just the kernel
icy wagon
Don’t have to worry about people targeting you if it’s your own os
warm sleet
@hollow basalt Linus Torvalds made linux after looking at the pricing for UNIX
hollow basalt
Creating an os is fun
warm sleet
Look, when people say "OS"
hollow basalt
That's the only thing I applied assembly
warm sleet
I only think: kernel
on windows thats NT
macOS is XNU (or Darwin depending who you ask)
hollow basalt
I'm the one that says darwin
warm sleet
everything else around the kernel, is just programs.
hollow basalt
That's the very thing Richard stallman preaches. Linux isn't an os
It should be gnu+linux
warm sleet
well
kernel is only small part of your entire OS
but if you wanted just an environment to run your code
you don't even need GNU
hollow basalt
They should be considered exclusive
vital blaze
On the subject of typing I prefer when my ide can figure out what type the variable is. Cause I don't have to be constantly looking at the online docs since I get the functions and their parameters in the ide.
warm sleet
yup
^
@vital blaze not only that
if you are at a given location in code
and you open autocomplete
it can filter nonrelevant things
IntelliJ does this to great lengths
hollow basalt
This is why notepad is powerful
icy wagon
Does anyone here use eclipse?
warm sleet
Eclipse is sack of shit
hollow basalt
Hell no
warm sleet
IntelliJ all the way
icy wagon
What do you use vim for?
vital blaze
Mobile developpement
vital blaze
Sometimes it's nice to work in a regular ide
warm sleet
latest verison of IntelliJ is unstable for some reason
multiple times now, its crashed on me
icy wagon
I’m running on like a 2018 build lmfao
hollow basalt
It's still ide
warm sleet
I got latest on here
vital blaze
Forget autoconpletion
@hollow basalt You can get autocomplete in vim.
icy wagon
What changes between updates
hollow basalt
Did I say you can't?
warm sleet
lol IntelliJ startup be like: https://i.imgur.com/2FornJP.png
vital blaze
I thought you where saying forget autocomplete and use vim. My bad
warm sleet
icy wagon
What changes in newer builds
hollow basalt
The version number
icy wagon
I noticed a big change when going from like 2017 to 2018
warm sleet
Why I love IntelliJ
Language Injection, Web services support, and you can configure run configurations for pretty much everything
hollow basalt
Cause you use java?
warm sleet
if I hit start, it builds the software, spawns a proxy server if there isnt one running
then it spawns a minecraft server
and loads my code, as well as load the binaries from the server into my IDE
so I can debug while its running
vital blaze
Yep
warm sleet
initially I got into minecraft development, to build a synchronization module for bungee
made a system where, players can move from one server to another through using portals
when you moved to a different world, you'd be connected to another server, using bungeecord
but my code, also makes it so your profile is transferred
as well as providing multichannel chat across servers
and discord integration, cus that is 'cool' to have
warm sleet
three plugins, one proxy plugin, one backend java service, MySQL datase and a redis database
we've had people try to steal our code
but i always say: good luck using any of it
icy wagon
Steal
warm sleet
cus you need a whole bunch of setup alongside to get it to work
its running on 8 server instances
the database is like 4GB now lol
icy wagon
Bruh
warm sleet
minecraft inventories so big
@icy wagon https://api.knockturnmc.com/standings
That should show you total amount of players we have
Its a harry potter roleplay server
Not my idea, I dont particularly care
but I like programming
and they needed a skilled coder
in 2014 xD
@hollow basalt
package com.knockturnmc.core.database;
import com.knockturnmc.api.database.BlockingCodeException;
import org.bukkit.Bukkit;
public aspect BlockingCode {
pointcut preventBlocking(): execution(@PreventBlockingCode * *(..));
before(): preventBlocking() {
if (Bukkit.isPrimaryThread())
throw new BlockingCodeException(Thread.currentThread());
}
}
I'm leaving for dinner, when I come back, I hope you figured out what this is
xD
icy wagon
Prevent a deadlock?
worn stump
Well now that a) I'm done with class for the day and b) I've gotten some sleep after my earlier messages, anyone know how I can contact Epic/Unreal re: github repo access? (The support rep basically fobbed me off and the Twitter DM I sent to the Epic Games Help acct hasn't been replied to)
hallow snow
Apparently you can overclock an ESP8266 to 346 MHz which is just simply insane considering the base clock of 80 MHz.

Hey oall
I have a Google Nest Mini and some Led lights with Controller i bought from a friend
my Question: can i throw some codeing (not my strong suit going to start learning it soon throw school) connect those two so i use "Hey Google Turn of all lights", Yes or no
cunning flume
okay thank u
nocturne galleon
made this in rust today and I'm in love https://github.com/Twister915/viz-rs

nice
warm sleet
Here's what will make any C project faster: find a commonly used header file and add the following:
#define true rand()
vague narwhal
would somone be able to help me with this code, it is saying that root = tk() is not defined
from tkinter import *
root = tk()
label1 = Label(root, text="hellow world")
label1.pack()
root.mainloop()
pseudo nacelle
i think this should help
root = tk.Tk()
#or maybe this should also work just fine, if u don't do import as tk
root = Tk()
Blech. Anyone have a contact email for the Unreal Engine team? I still haven't received an invite to the UE4 Github repo despite linking my GH account to my Epic one on Sunday (and AFAIUI it's done automatically/programatically)
errant raptor
so does anyone know how i randomize the background colors of the numbers without javascript? im using php html and css and maybe i roll the dice that it uses the dice to create a black border around the correct number?
nocturne crypt
if you want all the connections to go back to the server sure
you're now running into the logical fallacy of why and how PHP is difficult to use
nocturne galleon
php is all server-side
nocturne crypt
yes but if you understand how the client server relationship works
warm sleet
@nocturne crypt I can't do web without a pattern like MVC
nocturne crypt
you understand they can work together
nocturne galleon
javascript is your best option for something like this probably
warm sleet
SPAs are pure magic to me
nocturne crypt
like the reason why axios and jquery are so popular
is because they make this relationship less annoying
warm sleet
some guy on $internet said jQuery is dying
nocturne crypt
SPAs just require you to twist your head a little bit
jQuery is aging yes
using React with axios is apparently the new norm
nocturne crypt
i'm reigning it in with C++
i have a JIT compiler from my fully native C++ application
that will take C++ objects
and emit HTML5/css/js
warm sleet
at work they use Mithril (with typescript) to develop SPAs
nocturne crypt
because this has gotten to out of control
warm sleet
I'm currently working on a library toolkit, for node, that runs on both server & client
warm sleet
So you can develop SPAs, using definitions from a CMS
nocturne crypt
i'm just embracing the different libraries
and providing front end capability based on whatever the library can do
warm sleet
I hate node, I just... cannot find a reason why one would want to use it
its so easy to write the worst code ever in it
nocturne crypt
it is
warm sleet
the dependency and project lifecycle management is unrefined, garbage.
nocturne crypt
also all of my storage magic
is written in C++
and i'm like i'm not doing this in javascript
warm sleet
I have a tendency to develop API first applications
warm sleet
design interfaces, based on the user stories
@nocturne crypt Thats what I am using :D
The CMS I am using, is a SaaS, and its configured document types (its database) can export the schema
over GQL
nocturne crypt
i'm figuring out how to do GraphQL is compile time reflection
warm sleet
Using this to develop a toolkit for typescript with code gen
nocturne crypt
so you just give the object to the GraphQL engine
and it automagically generates the correct thing
warm sleet
mh
I've never implemented a gql server
only ever queried it
REST, I've got a good handle on
nocturne crypt
the C++ stuff for GraphQL is super tenious at best
but really GraphQL is just json replies
and understanding what the client asked for
warm sleet
Yeah the client to that CMS, is a combination of Rest & GQL
Definitions in GQL are the same types that the REST interface returns
nocturne crypt
less endpoints = less requried security
warm sleet
@nocturne crypt oh these APIs don't have auth xD
nocturne crypt
i'm thinking long term secuirty though
like if you drop a domain
and then people query the domain
and some malicious person buys the domain
like there's a million microsoft sub domains
warm sleet
well, not my problem lol. these people use a SaaS
nocturne crypt
because of rest
i can't wait to see how this explodes with ipv6
quintillions of restful endpoints
warm sleet
http://[2001::]/
or something
@nocturne crypt https://i.imgur.com/IP6JGJY.png
This is the way it is laid out
You query gql for the content, it has text & refs
nocturne crypt
i mean yea
warm sleet
refs are just urls to resources like images
nocturne crypt
i just like the fact that because it's one endpoint
you can ask and perform actions with one URL
so like HA is less complicated
uptime is less complicated
there's also action clauses in GraphQL
which i've never really gotten to yet
warm sleet
I've criticised GraphQL in my research
because if you use it to get all content for a page, and the database changes
it will not raise compile time warnings
but the code generator I use, does have support for generating definitions for defined queries
nocturne crypt
i mean
this is why i use AOTC languages
so the compiler can correctly tell i'm wrong
and that i should sit in the corner
with mandatory exhaustive pattern matching for dealing with runtime errors
exceptions are so stupid
warm sleet
Idk, in java, exceptions feel quite easy to use
never really had much of an issue with them
nocturne crypt
the problem is forwarding exceptions
like if you want a Promise or something
and an exception is thrown in another thread
warm sleet
Promises are a curse.
nocturne crypt
because of exceptions
promises and channels are simpler if you just don't allow exceptions
warm sleet
Promises ruin your entire threading model
use a message pipeline if you want to decouple that
nocturne crypt
promises and channels are just eager forms of parallelsm
the way promises are implemented in my version of GCD
is a message pipeline
you just call a function, it returns a promise
the function gets thrown into a lock free multithread safe queue
and gets popped in a threadpool somewhere
in C++ Promises basically use whatever exeuctor model you give them by the standard's rules
so you an do async now which is probably what you're thinking of
warm sleet
typescript hides this
if you make an async function
it just makes it return a Promise<T>
nocturne crypt
you can ask it to execute on a threadpool
or you can ask it to execute on a strand
Linux, Windows, and macOS all have a global threadpool you can access in C++ land
warm sleet
less software trickery with those?
muh, in Java, when you create rest services, every request is its own thread
nocturne crypt
yea typescript probably just eagerly uses async and spawns a pthread like a dumby
the global threadpools just act like normal queues
warm sleet
it uses whatever node does underwater
nocturne crypt
most of them use lock free thread safe threadpools
windows 10 is infamous for having terribly scheduling
so if you care about the actual scheduling in your threadpool, you can just use your own or ask for an executor from a third party library
like Apple's GCD or Intel's TBB (an OS agnostic threading library for C++)
Apple's Grand Central Dispatch became so famous that it actually has a port on LInux and Windows
warm sleet
I think java has ExecutorService
for that
it can hold a pool of threads
you can submit jobs to
jobs in the form of Runnable
warm sleet
the manual way of doing it
nocturne crypt
Java lets you do to many cool concurrency things
warm sleet
is by doing new Thread(() -> System.out.println("hello world"));
nocturne crypt
and people let it ruin their parallel workloads
nocturne crypt
that's probably some interpretation of std::channel
which is basically a thread safe message queue
warm sleet
oof
here you go
private Profile getProfile(String uuid) throws InterruptedException, ExecutionException {
ExecutorService pool = Executors.newFixedThreadPool(4);
Future<Player> player = pool.submit(() -> getPlayer(uuid));
Future<Highscore> highscore = pool.submit(() -> highscoreService.getHighscore(uuid));
Future<List<Spell>> spells = pool.submit(() -> spellService.getSpells(uuid));
Future<Boolean> online = pool.submit(() ->
livePlayerDao.getOnlinePlayers()
.stream().anyMatch(p -> p.getUuid().equals(parseUUID(uuid))));
Profile profile = new Profile(player.get(), highscore.get(), spells.get(), online.get(),
familyService.getFamily(player.get().getFamily()));
pool.shutdown();
return profile;
}
calling many services at once
compile the result, and return
warm sleet
This is a crude form of paralellism
nocturne crypt
this is the funnies
warm sleet
where you have a set of calls, that each do stuff over network/database
This was a 'fix'
to an API call that took 350ms
and after this change, only 35ms
nocturne crypt
there's probably some sorcery in those functions
warm sleet
it also connects to like 8 different machines
with RMI
to request data from the gameservers directly
nocturne crypt
heresy!
warm sleet
it was either RMI, or setting up a webserver on every instance
RMI was less configuration
and easy to implement RPC with
nocturne crypt
going for a distributed db
warm sleet
until oracle happened.
nocturne crypt
and exposing over one of the boxes
warm sleet
and RMI is now ded.
nocturne crypt
like i'm basically using S3 Buckets as a distributed datastore
you can do coolio stuff like that
interesting solution though
only use pre-fabbed tools
warm sleet
I set out to develop an alternative using the tools we already have
nocturne crypt
I mean i basically cheat and use my OP tools
warm sleet
wrote a PoC for implementing RPC with pubsub redis
warm sleet
I am saddened by the slow removal of traditional java tools
like, the JXC tool was removed from the JDK
You could use that to generate xsd from your JAX-B annotated types
nocturne crypt
honestly java is a security nightmare
warm sleet
how so?
nocturne crypt
the JVM is a magical box
this is why container people are so afraid of ipv6
they're like containers, direct exposure
you mean all of java apps and python flask apps
have to be secure now
and i mean it's fine if you understand the required firewall rules
warm sleet
I mean, none of my Java applications are directly connected to the net
nocturne crypt
but in reality most people don't, because they cling to NAT
warm sleet
The webserver I use in java, does not have any fancyness to it
Jetty is quite barebones
I use NGINX as a reverse proxy in almost every scenario
nocturne crypt
then it's not directly connected to the internet now is it
warm sleet
Only real risks with java
is like with any other language
injection.
Shellshock, sqli
etc
nocturne crypt
nginx has some sweet stuffings
warm sleet
yeah but you cannot manipulate the stack in the same sense
nocturne crypt
like i have applications that don't actually depend on the standard library
warm sleet
abusing a buffer overflow to rewrite stacks
doesnt work in java.
because code does not have permissions to do this
nor, is there any API to do so
nocturne crypt
if you do C++20 stuff, abusing the stack doesn't work either
nocturne crypt
so C++ is like that moment when Ichigo is learning bankai
and Zangetsu is like you must understand
warm sleet
I love deploying this in software contexts that are very agile
and early in development
It basically hooks itself to your logger
nocturne crypt
what does it do?
warm sleet
and any exceptions you generate
it stores context information as an "event"
and pushes it to sentry
so you can see exceptions, categorized and grouped (if duplicate)
you can add markers
to add things like API parameters
so you can recreate the bug
warm sleet
let it crash?
nocturne crypt
all runtime errors are handled with pattern matching
