How?

Also I only have a T:\ drive.

WHY

Seems logical, it's a display device.

I suppose it should support the I drive as well.

Will it work on /mnt/C:?

It's a joke because it's a visual device that only works if it's located in the C (SEE) drive. See, it is a pun, or play on works. The poster also mentions that the I (EYE) drive should work. There you go, I have explained the joke and destroyed all amusement that was found within in.

>>8772302

My guess is DRM that doesn't allow symbolic linking.

Palmer has commented on this and said that's it a non-trivial issue for many reasons and on a 'roadmap' of issues they want to deal with which ought to raise red flags. This should be a trivial issue fixed in no time at all, it's literally nothing more than a directory path.

If you haven't noticed Jewbook dropped, or as they said "frozen", Linux and Mac support with SDK 0.5. Since prerequisite to getting on Oculus store is to use SDK 1.0 it basically means that Rift is Windows-only. And of course you need to make Oculus account to install the drivers and SDK, goyim.

>>8776008

I didn't know that. I barely follow OR, I had very little interest in it when it was announced and when Zuckerkike bought them it killed my interest completely. Looks like I dodged a bullet there.

>>8776030

As it stands Jewbook is now focusing more on GearVR since casuals don't want wired HMD and mobile market is more profitable so Rift is getting mobile treatment as well. Can't blame them, even Carmack says that mobile VR is the future because he's paid to say that.

>>8776035

OSVR EXISTS AND IS MUCH CHEAPER AND BETTER HARDWARE

NOT TO MENTION THE FACT, IT CAN BE COMPARED TO A CONSOLE, AT LAUNCH THERES NO FUCKING TITLES FOR IT

>>8776998

I dunno, I just wanted to see what the other anon was talking about.

That's pretty cringeworthy.

>>8776977

It doesn't have better hardware. It doesn't even do 90hz and the latency is shit.

PSVR is honestly the most quality for money you get out of all the platforms.

>>8776998

women in stem guys!

>>8777059

Anon, I asked for cringe, not programming wizardry that I'm already well aware of.

>>8777012

I know PSVR claims to be amazing but let's wait before it actually comes out, especially since sony had R&D done for them for free with all those early competitors, so either they'll learn from their errors or just copy them

>>8777124

The woman's code has a pointless and large number of extraneous comments that aren't necessary, because any programmer could tell on sight what those lines do.

The man's code does not.

The retards in the comments think that the man's code is worse for not having copious amounts of blindingly obvious comments.

>>8777124

The womans code is shit and wrong

>(a > b && b < a), gotta be careful in case a is both greater than and less than b at the same time

The right code can be condensed into:

return a > b ? a : b;

>>8777144

>The woman's code has a pointless and large number of extraneous comments that aren't necessary, because any programmer could tell on sight what those lines do.

>The man's code does not.

Oh okay, I DID get the point then. I thought it was something more complicated.

>>8777124

>>8777144

I don't think they would have understood what it was even if the sqrt code was properly commented.

>>8777156

>gotta be careful in case a is both greater than and less than b at the same time

Look closer.

>The right code can be condensed into:

>return a > b ? a : b;

Incorrect, it should return 5 if a == b.

>>8777124

left code optimized the fuck out of video rendering and right code doesnt work

>>8776977

>CHEAPER

Yes.

>BETTER HARDWARE

Not yet, 60fps is even worse than DK2.

>>8777156

Saw that in /tech/ but it's only now that I see how it needed to double check that a is greater than b.

>>8777215

60FPS on 120Hz screen. Not ideal but the hardware is there for 120FPS, it needs new splitter and tracking camera to get there, though.

>>8777233

DK2 makes do with a 60Hz tracking camera, so the OSVR camera should be more than enough already unless they are doing something weird.

>My guess is DRM that doesn't allow symbolic linking.

But the Oculus Rift is just a monitor! (As opposed to the times where it's convenient for me to say it's more than a monitor.)

Since it's just a monitor there's no way that Facebook can use its own tracking and metrics software to glean personal information from every Rift user!

>>8777144

To be fair the fast inverse square root algorithm is so obtuse it could probably use a little commenting.

>>8777124

It's a joke: on the left is a short piece of code that does a hyper-optimized thing but it looks like dark magic. The on the right solves a trivial problem in a convoluted manner with lots of "lol, so random" cutsie comments.

It's basically two extremes, on the one hand you have engineering ingenuity that border on magic, on the other hand you have "look mom, I'm a programmer now" tier code. It's playing with stereotypes. But the comments didn't get that it was a joke and assumed that the abomination on the right is quality code because they can understand it, thus confirming the stereotype.

>>8776998

The most known example of the algorithm on the left (idTech 3, although this function wasn't written by Carmack) was fairly commented because it is fucking bitwise sorcery, which is hard to understand in some cases, so it needs a little bit of clarification. Fuck, not even the guy who put that function in there knew how it actually worked, judging by his comments more specifically, the "what the fuck?" part.

The algorithm on the left is something most engineers can't comprehend. Someone happened to find a magic number that allows you to do this, and someone else happened to find a way to make this work with the usual way floating point numbers are stored in memory. It's mathematical magic, which is hard to understand, combined with circumventions around C's typing system (something that's pretty much language-specific), so it is doubly hard. Judging by the comments, I assume the guy who coded the function knew how the C sorcery worked, but didn't bother to understand the algorithm because he just implemented it, which is why you see comments around the C typing fuckery but not much thought put into the magic number magic.

As a sidenote, there are two girls in my programming class, and I can confirm at least one of them comments on every single line of her code without emoticons, of course. But I can't blame her, as our teachers are pretty fucking anal about enterprise coding standards and will reduce your grades several points if you don't put an excess of comments.

>>8777124

The left code is the fast inverse square root, which is one of the most commonly cited blocks ever written. It's used to approximately get the inverse square root, or 1/sqrt(n) (I'm going to assume you're not a complete retard and know what I mean by that), of a number and is used in Quake III for lighting calculations. The real magic is with the number 0x5f3759df for some reason beyond my knowledge. Read this for a more in-depth explanation:

http://h14s.p5r.org/2012/09/0x5f3759df.html

The right code is used to compare two numbers and will return the larger number. If they're equal, then it will return 5 because women are retarded.

>>8777272

They are doing lots of fucking weird, position tracking works really great with HDK1.3 and latest version OSVR server but the IR tracking code is basically straight out of 90s - Sensics reused shit from the days when they were still developing HMDs to be used with SGI workstations. It will take a complete rewrite of some parts before they solve the motion tracking and display not being in sync.

>>8777416

What the fuck?

my brain is melting trying to understand this.

>>8777513

Just read everything before the What the fuck? to get an overview of the code part. The rest is just showing the math behind it.

>>8777574

yeah I got that the explanation before that I am talking about the math part. it's really fascinating

>>8776998

Her code isn't even indented properly.

>>8777416

I forgot to mention that the reasoning behind the purpose of the fast inverse square root is because finding the square root normally is particularly taxing on the computer. While the fast inverse square root isn't exact, it's accurate enough to the point where no one will notice and it's process around four times as quickly than if you were to find the actual square root, which is:

1 / sqrt(n)

Please excuse me if I fucked this up. I only have just begun to study programming.

And enterprise code still winds up being utter fucking garbage that doesn't even do what it's supposed to be doing to full extent, and what it does it does with absurd amounts of quirks and glitches.

t. heavy duty manufacturing factory worker. I'm an excellent programmer but I'm not allowed to fix those god awful dogshit turds of a software.

>>8776998

The way code on the right works is not hard to understand really, the only complicated part is derivation of the magic number. Multiple people did this through trial and error, and there's multiple such magic numbers that exhibit different overall accuracy and maximum error.

So first it takes bits from a floating point number and puts them directly into space for an integer, not changing anything. Important thing here is that floats and ints have different bit representation. Integers are just digits left to right, same as regular numbers we write in decimal system e.g. 17711488. Floats are equivalent of exponential notation, i.e. front few bits are reserved for exponent and remaining bits are fractional part e.g. 9e3.

Then it bit shifts resulting bit map one place to the right, also discarding rightmost bit and adding an empty (zero) bit on the left. This is an equivalent of integer division by 2.

Then it subtracts resulted value from a magic number. You have to pick magic number in a way that, when mapped back to float, results in an equivalent of coarse operation of inverse square root calculation.

Then it does exactly that, maps resulted bits to a floating point number.

Last step is newtonian algorithm to improve accuracy. One step is sufficient to even out inaccuracy to a good enough degree not to be really visible to a naked eye.

Spot a python fag. The slash-asterisk-slash or double slash commenting pattern is standard for absolute majority of programming languages, except special snowflake ones like aforementioned Python.

>>8785639

I actaully haven't used python at all but enjoy bash scripting.

>>8777333

Which fucking idiot designed that. SSDs are not big enough yet for most people.

>>8785772

You need source on this? Are you fucking bullshitting me?

>but enjoy bash scripting

Yeah I guess bash is the only thing you've ever "programmed" with, that and ini files. That would explain your bullshit remark about comment line conventions.

>>8777369

While I feel the left block could use some comment, I personally thought the biggest joke about the right block is the fact that 5 is returned when shit is equal. Yes, some other things are pertty stupid, but thats about the fucking worst.

>>8785872

>You need source on this? Are you fucking bullshitting me?

Nope I am not.For once. As it has been established I have done any thing that would be considered programming and I realise that.

>Yeah I guess bash is the only thing you've ever "programmed" with, that and ini files. That would explain your bullshit remark about comment line conventions.

>>8786076

Just because there is a workaround doesn't mean its acceptable for them to do this.

>>8777059

But in what context could this wizardry be implemented?

>>8780045

This site explains how the magic number was obtained:

https://archive.is/0iwYd

Of course, the magic number itself was dependent on another seemingly random number as a function which the article links to other sources. Considering everything, it's rather astounding the wizard(s) that found this trick.

>>8785912

C had the slash-asterisk multi-line comments, C++ added double slash single line comments. C's syntax turned out incredibly good, so most other languages carried that over.

>>8786322

I was expecting a way harsher reaction.
