How does /tc/ sort their files? Do you throw them all in New folder (62) or do you take the time to sort them nicely?

I've taken up archiving as somethig of a hobby over the past year and with it I've noticed the way I store almost everything is woefully inadequate. It's not really that bad but I know it's a problem I need to get ahead of.

Based on my experience + google these seem like general best practices, if you have input on any of this I'd like to hear it,

-Don't rely on any external program. At any moment the project could stop being maintained and if it's closed source you're shit out of luck. Open source projects aren't as problematic, they're easier for someone to fork after the fact but that still introduces a rather large point of failure. Are they worth using? Yes, but as an additional tool, not a replacement for a proper directory strucuture. Software used for this should ideally be FOSS, widely documented, and popular with the correct crowd (that being archivists/data hoarders/pirates). Calibre is a good example. If calibre ever stopped being maintained you can be sure there'd be forks or at the very least some way to get the massive amounts of metadata out of it and into another program.

-Be platform independent. Don't store your files in some weird way that renders them unusable on other modern filesystems you might find yourself switching to.

-Be consistent. For whatever reason I've given some of my anime the romaji title, some of it I've given the english title. This can be something of a headache when I go to check whether or not I actually have something downloaded and has led to more than its fair share of dupes. A simple folder naming convention of (japanese official name)-(common english name) for such things can go a long way towards preventing these headaches and if I search for either title it'll come up.

-Have a plan for when you have to split directories without an actual split in content. When you have thousands of files/folders in a single directory explorer loves to either slow to a crawl or just crash entirely. For things like music and books this is an easy problem to solve. Sort by the authors name first, and then group those named folders alphabetically.

For reference here's my artwork folder (my plans for it anyways) in more detail. It's basically the same story in photographs with a handful of folders removed and added. There'll be more I'll have to make as I go, but this seems like a good start.

I'm at something of a loss as to how to sort fanart in particular. It's difficult to create a copy/pastable folder structure that works for every series. It's all too easy for one or two folders to become saturated with all the content while the others sit empty. Kind of kills the point. For this reason I think it might be best to only bother sorting series with a lot of art into further folders, and only sort by character when the series has a ton of characters like Touhou.

I've seen people mention HydrusNetwork before but that doesn't seem like a real option. It'd just take too much time. There's the big upfront cost of tagging all my existing pictures and then there's the ongoing grind of tagging everything new. I love the idea of a desktop booru but unless it's going to find some way to crowdsource the work it's just not worth it.

How do you do it anon? I'm curious.
>> No. 1812 [Edit]
I keep maybe 1/4th of my animu photos sorted by series. In some cases I have special sub folders for characters such as the waifu, saber, ect. the rest get tossed into a big general folder that I keep telling myself I'll sort out someday knowing full well I never will.

My audio is a bit better sorted. It's not ideal but I have a music folder, and from there groups/artists. few exceptions being folders for game music, soundtrack stuff, ect I do have a small general folder of sorts for music but that's just from when my only hdd died and I had to rip my music off my ipod, and because of how poorly it was stored the files were given randomized names and placed in random folders.

Videos is pretty straightforward. anime/tv/movies/other. sub folders with series names.

Games is also pretty simple. It's mostly just sorted by system.

This thread is computer/technology related, so /mt/ is probably the best place to post it.

Anyway, to the point. I've been hearing many rumours that the soon to come Windows 8 will have forced "Live integration", which means (you guessed it), forcing you to register on Live before being able to use the OS. From that moment on, I realized that Microsoft will either fail completely as a Software manufacturer or the oblivious masses will bend over. To my (almost expected) disappointment, it is the latter. The masses will accept this as they have done so far. I'm talking about the social networking shoved in people's faces everywhere. You can't go to a large website without seeing facebook and twitter links everywhere. Hell, even online gaming has turned into one big social network (see Steam, Xbox Live, etc.)

The question I pose is, what's next? Requirement to have your real name visible everywhere you post? Or maybe forced cloud computing? Web 2.0? Seems likely.

They're already putting tracking devices in smart phones:

And don't get me started on the backdoors they've put in proprietary software.

Well, this concludes my pointless post. Any thoughts?

Why partition your HDD?
More importantly is you should encrypt your harddrives, use veracrypt.
>> No. 1791 [Edit]

I've only used TrueCrypt and later VeraCrypt with flash drives I was afraid of losing outside. Even then I only made separate file containers, never full drive encryption.
Does doing that on PC require a clean HDD, or can it be done with ones already full without losing any data?
I also have BitLocker available but never tried enabling it.

An cheaper way to get 8tb HDDs is shucking i.e. buying an external HDD and taking it out of the casing. You can save a lot of money this way. Buy the My Book 8tb (Less than 8tb disks are said to be blues) and take the hard drive out of the external case. It has a white label now but it's the same as red, might even be a HGST He-10 drive (not 10tb though).
I used part of its packaging material and a TX8 screwdriver, it worked for this guy with guitar picks and pliers.

You can reuse the case for other disks with a simple modification explained here:

It has to be encrypted with an existing OS and no files will be lost, you can use your computer while it's encrypting, there shouldn't be any problems (I haven't had any). Encrypted OS will ask for a pre-boot password, this will be in US keyboard layout.

As for devices, you will be given an option to 'encrypt and format' or 'encrypt in place', former is the fastest but all existing files on the partition/device will be lost, the latter will keep your files intact but encrypting will take looonger the more data it has.

In both cases make a backup of your files, just to be safe. After successful encryption transfer files over and secure erase the unencrypted device.

I've been wanting to try programming or game making for a while now but I don't know where to start. I have a vague idea of what I want to make. Ideally, something like a point and click adventure game but rather than having an inventory it'd be more about how your actions affect the things around them. If you've ever played ghost trick I wanted to make something like that. I really enjoyed that games puzzles and I liked how a scene was being played out as you solved them.

But trying to emulate that kind of gameplay is too ambitious for a first try so maybe something closer to "I wish I were the moon"

Making video games is difficult and learning any language is extremely tedious. The software I write nearly every day is what most people, myself included, would consider boring and the tedium is absolutely inescapable. It will more than likely take great resolve to do anything you have in mind today.

If you decide to program it yourself you should learn java and get comfortable with that. Java is a fine language for beginners and teaches useful OO concepts.

Assembly and Python are also excellent starting points for beginners, Python will teach almost everything a beginner should learn. It's easy to use and would make a great stepping stone if you want to later use a language like C/C++/Java. Python is great in and of its self and you can stick with it. Assembly takes a bit of effort to learn, but it's still by far the best way to really get to grips with programming, but I still recommend it less than Python and Java.

If you decide you aren't tough enough and programming is not for you, there are things like Wintermute Engine and Visionaire Studio that will let you make your game with little or no programming knowledge. They're really easy to use, so I hear, and they would suit someone with not so much time to invest in a hobby.

That is a point and click adventure game.

This kind of blew my mind, the fact that something we built is out so far, even if it's just a probe from the 70's. I know it's slightly old news, but considering how long Voyager 1's been out there I don't think a week makes much of a difference.

I'm aiming for a career in Mechanical Engineering so programming for me is going to be something I do to assist with prototyping. That is to say, it'll be primarily more of a hobbyist activity. On that note, I've decided to learn C first, then Forth, then Lisp and then Ruby.

C because I hear its simple yet powerful, "bare metal" programming language. I believe it also teaches you about how the computer works internally.
Forth because I hear it gets used in the Aeroplane and Space sectors of Engineering. It's even closer to the "metal" than C, I hear. I heard it gives the programmer immense control and presents its own unique problems to programming that challenge you to think differently.
Lisp because I hear it will induce some kind of revelation about programming when you come to understand it. I hear that it's perfect for when you don't know what you should be doing because Lisp code is flexible enough to be taken in a new direction with relative ease.
Ruby because I predict I'm going to want a more friendly language to code in for my own applications in the house when I'm not trying to be maximally efficient.
I also consider Ada and Fortran as possibilities.

My most recent completed project was a program that could print a list of all the palindromes from 10 to 1,000,000 without using string manipulation (since I have yet to learn it).
>> No. 1785 [Edit]
I would recommend LISP first, as you will get a better understanding of the science in computer science and better illustrates benefits of doing things different ways (especially recursion).
C is great exactly for the reasons you list, but the manual memory manipulation crap and a lot of C's idiosyncrasies (including the compilers) will slow down the general concept stuff that you should be learning first and foremost.

I would also recommend python over ruby for a language following what you are trying to accomplish with it, as python is a lot better supported overall, and a much larger library of publicly available code to stealborrow from.
>> No. 1786 [Edit]
Thanks for the support but unfortunately, I've already bought books on C to get me started with it. I'm going to press on with C just for the sake of reassuring myself that I didn't waste my money. Considering what you said though, I guess I could make Lisp second and I'll learn it along with watching those SICP videos on Youtube before going into Forth.

I've heard that Python is popular for being popular so I'm somewhat aware of how well supported it is. When I look at Ruby code though and how it's all so sterilised of all of the "computer" things that you usually find in software code, I feel really drawn to it. It seems really comfortable. I'll just have to keep Python in mind as well.
Thank you.

Just so people stop replying to this thread I'm gonna drop a knowledge bomb on you faggots.

It's called "Aerodynamics" and it's the reason airplanes have wings. You see, the wings generate lift by creating a difference in pressure, the shape of wings is such that air underneath is a higher pressure than the air over-top. Because pressure will always seek to reach an equilibrium, the higher pressure air will exert a force on the lower wing surface attempting to mingle with the much lower pressure air running over-top.

It is not the displacement of the engines that causes an airplane to travel upwards. This is idiot-proof when you realize that the engines are permanently mounted sideways, and couldn't possibly produce enough force downwards to generate lift.

The reason the airplane on a treadmill wouldn't work,(so long as the treadmill is rotating at a relative speed above the airplanes minimum take-off speed) is because it's airspeed is insufficient to cause a difference in pressure along the wing surfaces.

There is actually an effect similar to the treadmill mean in real aviation called "Tailwinds"; that is to say when the wind is blowing in a direction parallel to the planes travel, such that the wind is approaching from the rear to the front. It can, at sufficient windspeeds cause an otherwise airborne aircraft at the same engine displacement to stall and fall out of the sky, because the pressure differential under the wings is producing insufficient lift.

I recently noticed that one could express a polynomial in terms of combinatorials and so I am curious as to how far one could go with this.

My requests are:
1) An expression of n^4 purely in terms of combinatorials
2) A method for finding these combinatorial-expressions
3) Clarity regarding what the term is for this field of study my question would fit into (if there is one)

I notice Pascal's triangle appears consistently (albeit with the rightmost '1' cut off) so perhaps, keeping the positive-negative alteration in mind, the n^4 combinatorial-expression is actually quite predictable but I have yet to test this and to be honest, I'd rather find a method than apply what I predict could be the cheat-sheet.

Also, since I originally stumbled upon this dilemma when trying to calculate the total number of possible pairings amongst a species consisting of two sexes, rather than balls and bins, do you think you could apply it to the scenario of a race with three sexes (but only a trio with one of each of the three sexes can produce a child)?

Or, if sticking to balls and bins, could you draw pictures too?
>> No. 1779 [Edit]
Not sure if I understand what you're getting at, but combinatorics is a field of math and I'd certainly put this in that category.

>My moment of genius was to realise that you could just take away all the possible male-male pairings
Yeah exactly! And your example actually *is* inclusion-exclusion applied to the case of n = 2 I think (expand out the summation and you should find that the terms match up)!

>do you think you could apply it to the scenario of a race with three sexes (but only a trio with one of each of the three sexes can produce a child)?
I'm not sure I understand what you meant. I'll give a concrete example for x = 3 bins and n = 4 balls though (so the number of ways to assign them is 3^4 = 81) (in your example I think this might correspond to each bin being one of the three genders). Also I'll stick to balls and bins if that's ok with you since that's a bit easier to visualize for me.

So we know that the number of ways to put 4 balls into 3 bins (with each ball going in only one bin and every ball going in some bin) is 3^4 (3 choices for the first ball * 3 choices for second ball * 3 choices for third ball * 3 choices for fourth ball). Now let's count this a different way. Form all possible ball/bin pairings:

ball 1 - bin 1
ball 1 - bin 2
ball 1 - bin 3
ball 2 - bin 1

I'm still in the process of trying to understand this post but for the time being, I have another question:
Is there any significance in applying calculus here? I've got x^3 expressed in terms of combinations and I've got x^2 in terms of combinations so it's not too crazy to triple the x^2 one (i.e. 3x^2) and announce one sum of combinations to be the derivative of the other. Does that yield anything interesting?

Also, with this ball and bin analogy, am I understanding you correctly when it's possible for one bin to have two balls?
>> No. 1782 [Edit]
>it's possible for one bin to have two balls?
Yes two different balls can go in the same bin, but a single ball can go in only one bin and every ball must go in some bin

> derivative of the other. Does that yield anything interesting?
No I don't think so since nCr doesn't make sense for non-integers. It's also pretty contrived so I don't think there's any direct interpretation. You can make 1 = 1 turn into some complicated looking thing by stringing together identities but it doesn't necessarily mean it'll have a direct interpretation.

Why do gpu makers put all their effort into making the top of the card look fancy when you're likely only going to see the side and the bottom? Why do the fans blow downwards anyway? wouldn't it make more sense to vent the heat upwards?

With these questions in mind it seems people are taking to side mounting their gpu, problem is that pushes the card right up to the case window and blocks the air flow. Anyways, what do you guys think about this? would you mount yours sideways, do you not care if it sags at the end when mounted traditionally, what's your take?
>> No. 1763 [Edit]
I am pretty sure the fans on most graphics cards blow air into the heatsink, leaving it to exhaust out the side or back of the card, then sucked up by the rear fan. Not much you can do about that but I think it works fine most times unless the computer not designed for a large card like that. There are also blower style graphics cards which use a radial fan to blow air through a duct and out the back of the slot covers, which works better in tight computers, it's pretty common. I think a simple reason for making the card look nicer on the fan side would be that those images are what is mostly shown in product pages where people purchase the cards, so people will buy the better looking one regardless of if they'll see it in their case or not. Most computers don't have a clear panel anyway so the majority of the time the side isn't even seen.

Air movement is more of a non-issue. The larger issues are generally going to be the heatsinks getting gunked up with dust. Make sure to blow out the dust every now and again.

With modern cases, there is plenty of room to prevent air from stagnating and heat up.

The real problem, as can be clearly shown in your image, is the PCIe ports being completely blocked. God forbid you want to use one of the new and fancy SSD drives, or a good quality sound card, or a network card.

Also, with multiple card set ups, you now have to remove everything to get to the card vice being able to lift out the problem card by itself. The cases and motherboards were designed with the vertical mount orientation in mind, both for air flow and ease of use. Changing that on a whim is a stupid idea, unless you *really* need to show off the LEDs on the fans of your graphics card which would be otherwise obstructed by another PCIe card.
