Q: Rendering primitive 2D shapes

Jimmy YangI am currently creating my own 3D renderer (think something like OpenGL). As a first step, I created a mini program below to render primitive 2D shapes essential to 3D graphics: points, lines, and triangles with z buffering. I'm hoping for code review on three essential methods in the class Displ...

@pacmaninbw Computers aren't secure enough. VMs aren't secure enough. Nothing is ever secure enough without context.
That's not a reason to abolish them completely.
Heck, cars aren't secure enough.
Things go wrong. People die.
People tend to get pissed when I ask about threat levels, but not enough people talk about threat levels.
Are you guarding against your neighbours of 85 years old, against a scriptkiddy nephew or against a hostile state agent?
'enough' implies you can guard against a specific threat efficiently.
Not against any and all threats.
Elevators are secure, unless you let me loose on them with a 1000 bucks toolkit.
Is that secure enough?
Usually.
Or if you let me enter the machine room, in which case I can override all safeties with loose wire and a screwdriver.
Older elevators are still in use. They are protected against most methods of failing and when they fail they fail mostly safe. Worst case you get locked up for a couple of hours and it takes a firefighting team to get you out. They are not as secure as new ones against various threats. If the new ones are 'secure enough' as well, does this imply the older ones aren't?
Technology is dangerous.
Humans are dangerous.
Security is relative.

I would like to have reviewed a .java file that is 90+ kB, which is larger than a single post can fit (64 kB as far as I understood). My options are: (1) split it in two posts and request the answers to only one of them; (2) strip away some code. Which way should I proceed?
 
11:43 AM
@coderodde Why is the file so large to begin with? If it's a library of sorts, maybe the first point of review would be to split it up.
You could split it up into multiple questions. Has been done before. Do note how few answers those questions got though.
Just because it's possible (and allowed) to post it like that, doesn't mean it will lead to reviews.
 
11:58 AM
@Mast Not a library, but a single data structure.
 
@coderodde A 90+ kB data structure? Ok. Personally (not from a moderator perspective) I think this wouldn't work well on the site. At that size, you may be better of to have a review of the approach instead of the actual implementation itself. That's not something we can handle though, but approaches is something Software Engineering can work with.
 
I think this site is more suitable for your question codereview.stackexchange.com Anyway, add some comments and give your variables meaningful names to make the code more readable. — Vitalizzare 27 secs ago
 
@coderodde To answer the original question: don't go for (2). (1) could work, but the likelihood of your data-structure actually getting reviewed isn't high.

@DerKommissar Do you know how to remove the hard drive from a Canon multi-function Laser Printer. I can recycle the printer after I remove the hard drive. My SSN is on the hard drive.
 
Nope, can't help with that unfortunately.
 
@pacmaninbw Smashing it into pieces will maybe remove the SSN ;)
 
@skiwi Yes, once I remove the hard drive that is what I intend to do to the hard drive.

Lists are useful data structures, but sometimes you need to show the context between items.
 
@pacmaninbw Considering the printer is useless without the drive, take it apart. Start with the screws, end with a crowbar.
Once you start breaking away plastic, some of the parts can be salvaged if you want to.
But the printer as a whole isn't salvageable.
Once you get into that mindset, it becomes incredibly easy to find the drive.
If you have a column drill, that drive doesn't stand a chance.

Q: Any bettter way to achieve this lookup table?

JohnWhat I need: I need a lookup table. Once the keywords are all found, then the value of the std::unordered_map is returned.And I don't care about the sequence of the strings in the std::vector.

@pacmaninbw The biggest problem is SE has hidden the manual and many of those that can find it either don't read or don't understand it.
If we'd all be forced to take a written test before participating, the quality would skyrocket.
Participation would drop through the floor though.
@pacmaninbw Commented and rolled back. Technically you were both right. The edit can stay.
Actually I'm not sure the question should stay open.
Half the code is missing.

@CaptainObvious Authorship!!!
 
9:57 PM
@pacmaninbw we don't know for sure since the OP hasn't replied but the implementation of malloc does look a bit different than the code in the referenced SO post (other than the last two lines) and also drastically different than the code in the other SO post mentioned within the second commented line at the start of memory.cpp
I searched the repos in the linked GH account and see two results but they are quite different and were last updated April 26th
