lel, heard the same thing about parallel threading a few years ago and we are still waiting.
hey uh
I interviewed and was offered an unpaid internship. Do I go ahead and take it? I know there's a lot of stigma against doing work for free, but damn, the experience really would look good. Also, this is my the end of my senior year in a CS degree and I haven't done an internship yet.
>>53912601
I thought the point of an internship is not doing work for free.

>>53912590
multicore was originally slated to be released in january, so not sure where the "years" is coming from. and algebraic effects is coming with that.
at least for now we'll be getting flambda which should bring OCaml's speed way past the current "functional programming" standard of speed

That unpaid internship will actually make your resume look worse than if you had just NEET'd it up for that gap of time.

I think it's more the fact that in the IT industry experience tends to get people jobs.

tripfag's right
Unpaid internship literally means "we picked this guy off the street to do our bitch work. He's gonna break his back making copies and buying coffee for the people we do pay, like this other intern, because he thinks people are going to take him seriously after we give him a year of bitch work with nothing to show for it"
I demand paid internships, not because I need money, but because companies are less likely to fuck around with you because they're actually paying for your time.
It has also been said that your value as a human being is as high as someone is willing to pay for. So, before you pick that unpaid internship, you gotta ask yourself, "Is my time really worth *nothing*?"

Now, the logic behind this could also be used to say "charity is worthless". It isn't, but giving charity to a company that can make money on its own selling products is pretty dumb. If you're going to do free programming, at least do it for a noble cause. Although, strictly speaking, if you're doing an unpaid internship, you're not doing free programming, you're doing free coffee making.
>>53913116
It doesn't strictly mean "charity is worthless"
Charity is something performed only by people who already have value, and its value can be interpreted as "this activity has equal or more value than the equivalent time that someone would pay him for."

Let's say I have a C program that just generates random hashes and prints them to stdout.
I want to make it multithreaded to take advantage of all my cores.
If I make the threads wait to print to stdout, then I can avoid race conditions.
Is there a way to keep it portable, or do I have to add #ifdef flags for both linux and windows?

I'm using Python to build a network of logic gates.
For now, I've implemented a system that simply iterates through a list of gates likedef OR(a,b):
s = a or b
return s
def NOT(s):
if s == 1:
s = 0
else:
s = 1
return s
def timeStep(t):
t = t + 1
return t
seedValues = {
"init": 0,
}
#define initial vals
gates = {
"gateA": 0,
"gateB": 1
}
t = 0
m = 0
#data table header
print "t\tgateA\tgateB"
#run logic gate loops
while (t < 20):
gates["gateA"] = OR(seedValues["init"],gates["gateB"])
print t, "\t", gates["gateA"], "\t", gates["gateB"]
t = timeStep(t)
gates["gateB"] = NOT(gates["gateA"])
print t, "\t", gates["gateA"], "\t", gates["gateB"]
t = timeStep(t)
print "\ncomplete"
This creates problems if I want a larger network. I want the gateA-gateB-loop to oscillate (unless something breaks the loop), but if I build a larger network it will only oscillate whenever my function "happens" to time step by.
Can I implement a time step function where every gate updates more or less synchronously with time?
>>53913527
Oh yeah, the output of that run ist gateA gateB.

>>53913560
>coding in C
Heh.
>I don't get what "update synchronously with time" means (well apparently you don't either Mr. "more or less")
I mean that I want a time step to cause every gate to be checked, not just checking one node at a time. I don't really now how to put it any better (my terminology's probably rubbish).
>>53913579
>every gate to be checked, not just checking one node at a time.
So you would have all nodes updated based on the previous state of all the other nodes? Also seedValues seems meaningless to you right?
show me a diagram of your network in EE style. Also is the output you posted in >>53913530 (which I understand is produced by >>53913527) conform to your specification or not? Guess not but...
Is this a nor latch?
>>53913605
Here's a more dynamic example: code below with corresponding EE diagram in pic related.def OR(a,b):
s = a or b
return s
def AND(a,b):
return a and b
def NOT(s):
if s == 1:
s = 0
else:
s = 1
return s
def timeStep(t):
t = t + 1
return t
seedValues = {
"init": 0,
}
gates = {
"gateA": 0,
"gateB": 1,
"gateC": 0
}
t = 0
m = 0
#data table header
print "t\tgateA\tgateB\tgateC"
#run logic gate loops
while (t < 20):
gates["gateA"] = OR(seedValues["init"],gates["gateB"])
print t, "\t", gates["gateA"], "\t", gates["gateB"], "\t", gates["gateC"]
t = timeStep(t)
gates["gateB"] = NOT(gates["gateA"])
print t, "\t", gates["gateA"], "\t", gates["gateB"], "\t", gates["gateC"]
t = timeStep(t)
gates["gateC"] = OR(gates["gateA"],seedValues["init"])
print t, "\t", gates["gateA"], "\t", gates["gateB"], "\t", gates["gateC"]
t = timeStep(t)
print "\ncomplete"
Output:t gateA gateB gateC

It might be now, but later on I'm gonna have it change under certain conditions, to see perturbations of the gate system.
>>53913693
That pic is wrong. I meant this.
I have the following problem:
[b]Letter[/b] is a [b]PriorityPackage[/b] of the lowest priority. It is an error if the Letter is weighing over 500g and has a displacement over 0.001 m^3. It has a text output in the form of "P"+priority+"["+ID+"("+weight+","+displacement+")".
package Postal;
public class Letter extends PriorityMail {
public Letter(double weight, double displacement,Value Priority){
super(double weight, double displacement, Value.lowest);
if (weight >= 500) throw new IndexOutOfBoundsException("Damnit");
}
}
this sorta works. However, i want an exception to happen BEFORE the constructor, but I cannot have that because of the [i]super[/i] keyword.
public class Letter extends PriorityMail {
public Letter(double weight, double displacement,Value Priority){
if (weight >= 500) throw new IndexOutOfBoundsException("Damnit") ;
else
super(double weight, double displacement, Value.lowest);
}
}
In c++ it would be valid for the constructor to throw at any time, even if the object isn't initialized or formed properly.
The idea is to have a priority queue of polymorphic, abstract Mails, which would be determined at runtime to be Letter, Package or sth else.
>>53913693
>>53913736
I see
If you want every node to be updated at once, you're probably better off generating a brand new gates dictionnary at each step while keeping the old one as an immutable reference, rather than trying mutating it, which destroys information, don't you think? thengates=newGatesat the bottom and you're done maybe?

Have you tried adding indexes on relevant columns?
Are you running your MySQL instance on a shitbox laptop?
If i may,
i'm trying to program a computer algebra system.
I'm using C++.
the problem i have is i can't find a way to represent and connect data.
i figured i need to have the data in a tree form.
After some research i came to the conclusion of 2 basic data structures,
a leaf node which i'm planning to have a father class and multiple inheriting classes which are defined based on what that leaf node is i.e. variable, fraction, and so on, and a connection node that is compromised of a vector or list, i'm still thinking of a way to handle this.
the problem is how do i mix those two together,
lets say i have this list [x,2+3,3,4]
it should be a vector of (variable, expression,number,number)
the expression is a connection, while the other three are leaf nodes.
i though of giving them all a united father, but that makes traversing the tree a bit hard, and makes stuff like comparing two trees even harder.
the two main types look like this for nowclass Leaf
{}
class Connection
{ vector<Connection> members; }
leafs being determined through things likeclass var : leaf
{
string name;
}
class fraction:leaf
{
int a,b;
}
any help would be great. i feel like i'm missing something and i am going through c++ books and looking at data structures.

Practice consuming, manipulating, and presenting lots of raw data.
For example, pull in megabytes of raw text from an API or database, do creative things with the information, and show interesting information on an interactive GUI.
Make sure you're aware of best-practice and how to make your code very readable.
Learn the shit out of LINQ and how you can interact with enumerables with LINQ.
You should also learn the basics of SQL and how to write some simple queries.
You can use the free AdventureWorks database for these things.

I'm working on a program right now that will pull inner text of specified tags, ids and classes within an Html page, and organize them into comfy lists.

Scrapers can be quite useful, but if you're scraping a website's HTML when it has APIs, that's usually not good design.

Scraping HTML is suffering.
Playing with CAS calculators and python I was wondering if the transposing of an equation to make it useful has to be done by hand?

>>53915148
>if you're scraping a website's HTML when it has APIs, that's usually not good design
My thought was actually that it's probably would be good practice to create a program that can pull data without any 3rd party APIs.
>>53915190
No no no, you've got it backwards.
Let's take something like OpenDNS Umbrella's console for example.
They make constant changes to the UI of the website, shifting elements around, in order to improve the user experience.
However, the APIs that expose data and functionality and authentication remain consistent.
This allows a company to write an application utilizing their APIs and not have to worry about constant changes.
The idea is that APIs should remain consistent, so that people can develop with them.
>>53915190
It would, but it's a pain and like the anon below said sites change a lot.
>>53915234
As in programming practise. Not best practise.
>>53915174
Oh shit thanks bro.
Another question is that does it only work with Algebra?
>>53915234
I meant literally good practice for learning interactions with Html in C#.
Obviously I know that for a final product one should use an API if available, that makes sense.
But I'm not making a product but a demonstration of my abilities.
My next step in this plan is to make a program that does the same, but for a specific site using it's API, to demonstrate I can use them properly.

Regarding interpreted languages, when is the compilation done of given source code? I mean although its "interpreted" it must be compiled to machine code at some point right?
>>53915351

>>53914385
ok i guess no one here knows how to go on fixing this. then if i may anyone that understood what i wrote could help me out make it clearer incase i ask this again.
>>53915450
No, the interpreter is your machine code, the code only gets parsed and interpreted (eventually converted to underlying VM code).
http://thedailywtf.com/articles/Income
>when Pajeet codes
>>53915450
It's parsed, sure, but it's not compiled to machine code. As the name implies, the interpreter (sometimes VM) takes the instructions from the parser and executes them by setting up a state machine and looping on the parser output.
>>53915510
So it first goes to interpreter and then to CPU , interpreter has hooks to CPU's instruction set? Does this means that interpreter already has compiled commands that serve as bridge between source and cpu without waiting to compile ?

>>53915640
What about them?
>>53915598
>>53915617
In precompiled languages the parsing and compiling is done ahead of time, so the only step left is to make the CPU run it.
In interpreted languages a different program must also be running and reading the source code to actually execute these instructions by running code that the processor understands. The mapping is not 1:1. Get your head out of your ass.

Consider this example program:void add(int a, int b)

}
void sub(int a, int b)
{
fprintf(stdout, "%d - %d = %d\n", a, b, a - b);
}
int main(int, const char **)
{
std::ifstream stream{"data.in"};
std::string line{};
std::string op{};
int a = 0, b = 0;
while(std::getline(stream, line))
{
std::stringstream ss{};
ss << line;
ss >> op;
ss >> a;
ss >> b;
if(op == "add")
add(a, b);
else if(op == "sub")
sub(a, b);
}
return 0;
}
You compile it and that's your "interpreter", now you feed it a file with "add 5 5", "sub 10 5" and so on, it "interprets" those and calls appropriate functions.
>>53915681
You mean you want to get the information that the /page at that URL contains/? In which case you need to keep making requests to these URLs.
>>53915672
Its just that the explanation for how interpreted languages work is blurred (at least in sources that I found on internet). Its always something like "it doesnt compile, it reads line by line and executes etc." but nobody goes into what is actually happening between interpreter and cpu since cpus supposedly understand only one type of language.
>>53915330
Oh yeah, but for some reason I have an aversion to turning ranges into expressions.
>>53915701
Well I guess I just need to find a way to make dynamic requests based on the urls that are parsed.
It would be better if the API already returned the objects filled with the data instead of URLs.
Thanks anon.
>>53915640
Looks like poor API design, because it's storing relational data as a full string path, rather than just the primary key referencing the data.
You could regex those URLs down to their ID, so that your"starships"would just contain 12, 24, etc.
Create multiple objects to maintain relational references.
In this case, you can have Character objects, and that Character object contains a list of references to Starship objects, etc.
>>53915793
>It would be better if the API already returned the objects filled with the data instead of URLs.
That violates relational design and would end up duplicating tons of data.
Let's just say that each Starship object is 1kb of data.
If 10,000 different Character objects reference the same Starship, you've just created 10,000kb of extra data for no reason.
>>53915808
I agree with you anon, it should at least have the direct ID of that object.
But I am not the developer of this API, I am just consuming it in an Android App that I am developing to study.
We should have a /dpt/ programming collab guys
>>53915869
No good can come from this.

I see, make a lot of sense.
I just said it would be better in my perspective but your POV is great.
Having URLs as attributes is a common scenario in a real world APIs?
>>53915869
Alright, but surely we cannot have a collab without a proper logo.
>>53915877

Is 'the C programming language' good, as in difficult and challenging, hopefully a little more difficult or as difficult as sicp?

>>53915903
You have an interest in programming.
You could start studying and learn programming. In the end, it's always a handy skill to have.
>>53915903
>>53915890
>Having URLs as attributes is a common scenario in a real world APIs?
Not as a reference to another object within that API.
Like I mentioned, it would have been better as a list of IDs, as the attribute specifies that it's looking for "starships" or "species".
4chan's API, in contrast, does not actually benefit from relational design, as it is very 'trickle down' in nature. There is no relationship between a thread on /g/ and a thread on /b/, other than if a post links to one another, but this is not utilized by the application itself.
How do I "reverse compile" the executable file back to its source code so I can cheat big corporations and see their protected source code?

It makes even simpler for me to understand and create a code if it was a list of IDs.

>>53916006
You're making me feel all warm and fuzzy.
My perspective on these things is from a database architecture viewpoint, so I'm used to looking at things in a relational-data-oriented way.
I highly recommend learning some relational database fundamentals, as relational algebra and the related fields are the basis for many ways in which non-trivial application store data.
/dpt/ can be fun, but isn't always the best place for good advice. Try to find a smaller forum or IRC to bounce ideas off of people who actually do these things regularly. Better yet, get a job and you'll learn way faster than anything else.
It's a shame there isn't something like a more relaxed, less anal-retentive Stack Overflow.

I've done calculators and shit in c# that's it
>>53916223
Calculators are fun to write in any language because the parser theory is far more important than the actual calculations.
so me and a friend are working on a database for fun.
he won't accept that what he has done is false.
what we want is have each user be given a set of permissions of what they are allowed and no allowed to do.
what i offered is having a permission table and a uer_permission table holding an id of the permission and id of user as a key.
he went on things through pic related and won't heed my calls about how he is wrong and that its a waste of storage and time complexities as well as allowing for a lot of duplictes.
he pitched in that there should exist permissions, then roles of which each hold a set of permissions, then users get a set of roles.
now i know i might not be right in just taking in permissions + user accounts. but adding roles that way is worse than what i thought of.
Can anyone suggest a better model to go with?
i thought of a middle ground where we can have roles, but users aren't allowed to hold more than one role, since a role could alredy cover permissions of another role.

Unfortunately, now the most common words are "prince andrew" and "emperor alexander", so I need to pick better source material, or write a better lexer (perhaps just ignore any words beginning with a capital letter).
Here's a couple sentences.longing to be a man who was not know what was the same time to the Emperor Alexander and the same time he was a man ofthe battle commence the same time to the Count who was the same time to the old prince Vasili and I am not know what is not

2d array. First dimension is the condition, second dimension is the output. Then you just do
[Code]
for(int i = 0; i < 10; i++){
if(strcmp(m, options[i][0]) == 0)
cout << options[i][1]
}[/code]
strcmp will return 0 if the strings are equal. Technically this is C, so there may be a better, more nuanced way to do it in C++ but this will work also

On a 64 bit system you should make all op strings 8 characters or less. Copy the characters from the op into a zero filled aligned buffer of length 8, cast the buffer to a long with a union, and switch based on the long values. It's faster than doing repeated strcmp.union {
long l;
