Hello there /sci/. I have a challenge for you. Take your favorite futuristic or otherwise out of reach tech from any movie (let's say a light saber) and try to explain if humans can replicate it with a few modifications.

so, I know you guys use word filters, or at least have a times, I have some questions about them, now, this being said, I'm aware that your guys' word filter isn't exactly used in the same way that this kind is... at least in spirit, or cause behind the technicalities

out of curiousity, does anyone know of any studies on manipulation of perception in a pervasive way involving mediums of communication and what is said or isn't said?
does anyone have any knowledge of studies involving methods of control that are linguistics oriented or say... are designed to pick up on related contexts and the like with various signifiers?

some stuff's popped up lately and I'm *extremely* interested in this, I might have to learn a fair bit of technical jargon and concepts but I feel like it's probably worth it

on the one hand it seems like the attempts to engage in this are laughable but at the same time I know that sometimes these sorts of things can get real good real fast, especially when there's already a load of collected data that's not purposefully spoiled to challenge the attempt at deriving context to start silencing apparently said things

Basically, my file/folder organization is pretty non-existent. EG: pictures folder has like 5 subfolders that make no fucking sense.

TL:DR how do you sort out your shit?
and are many fucks given about filenames

It's me again. I finally set aside some time to look at Hydrus. While its features definitely appeal to me, this is a deal-breaker:
My collection consists not of gigabytes, but of terabytes of files. Literally millions of files in a ZFS array. I simply cannot afford an import operation that performs a full file copy.

I am also tossing my hat in as a guy who had this idea independently. Mine is probably going to be written using the sfml library in c++ though. I guess a lot of us have similar issues :)

Hey, I'm ef54e2.

Would you be interested in working as a team on this? I already have a fully functional viewer and a PoC client/browser for the database, and a server. You can browse a virtual directory structure and open files with the image viewer. The server sends the file contents to the viewer through a socket (entire file resides in the client's memory; streaming is WIP) using a custom protocol.

You can take a look at the viewer code: https://github.com/Helios-vmg/Borderless
The server and browser code is private for now, but I'd be willing to share it with someone interested in working on it, of course. The client and server are written in C# (the server binary can run unmodified on both Windows and Linux) and the database is PostgreSQL.

Let me know, man. I really want to get this done, but my time is divided between my day job, real life, and other projects, so I can never find the time to work on this.

SSID ideas BillyJoeThePianoMan!!HjBTVkMQpk 15/09/29(Tue)00:57 No. 16202 ID: 8aea60 [Reply]

/sci/ give me some "edgy" SSID ideas, I can have up to four or five on my WRT54Gv5 with DD-WRT. I also figured out I can up the power to about 1.6 watts, but cannot get the -o command to turn on "override" where you can set basically any Tx power. Also I can use channel 12 13 and 14 freely :)

Other than SSID ideas that are "edgy" can you think of any illegal (in the US in general or wherever) SSIDs? Just for lulz.

Dont use channels so close to each other (eg 12, 13, 14), you will suffer the wifi gods wrath.

Hello /sci/. If there was a giant hole in the earth leading from one end to the other and- if you jumped in- would you just be pulled to the other side, or just be trapped in the middle by gravity?

Gravity is actually the force of all bodies in the universe pulling on all other bodies in the universe. However, the strength of the pull weakens with the square of the distance between two given bodies. Since the celestial bodies in the universe are so far apart, you can say for conveniences sake that you are only under the effect of the gravity of the nearest one (the earth).; in reality though, you are even (very, very weakly) being pulled towards other people, which means that the "your momma" joke about her having a gravitational pull is technically true.

You would lose energy and slowly oscillate and then come to a stop at the center.

Serious opinions about this new browser?

And I want honest opinions and not those entirely based upon the fact that a past iteration of the engine was not good. Like all things, they can improve or get worse.

It's trying entirely way too hard to be 'good', also it spawned an endless cascade of edge jokes, and I am not fine with that.

Arduino is a great place to start! Anonymous 16/12/30(Fri)09:26 No. 16404 ID: 01d2f8

Code academy and cybrary are pretty helpful sites but I really learned a lot building and programming little projects with the arduino mega2560. Jeremy Blum has some great tutorials on you tube to get you started. Also building raspberry pi projects is a great way to get your feet wet. Best of luck to you.

Nooby Anon 17/01/07(Sat)07:51 No. 16408 ID: 122f98

Also use Udemy if you have a little bit of money their courses are very informative and useful. Also very good for Python beginner courses.

Good luck bro

replacing speaker with 1/4" jack chrissychris 16/12/19(Mon)21:09 No. 16401 ID: 8ed2cc [Reply]

File 148217815616.jpg - (110.29KB , 1000x1000 , 7chan post photo.jpg )

Alrighty, I am looking for some help.

For the sake of experimentation and fun, I'd like to replace the speaker of a shitty kids toy (very similar to the one in the pic) with a 1/4" audio jack so it can play through a larger amp, possibly even through guitar effect pedals.

I've already tried this twice. Taken apart the toy, soldered in a 1/4" jack, and plugged it in. Both times I ended up with a reallyyyy spotty and quiet sound. At first I thought it may be a bad soldering job, but now I feel like it could be due to the low power of the toy, it takes 3 AA batteries.

So what's the deal here? Any ideas what could be wrong?

Anonymous 17/01/01(Sun)23:02 No. 16405 ID: 67f38c

It has nothing to do with the electrical power. Real electric guitars don't have any batteries. The issue could be that the amp is designed to work with the signals from a guitar's pickup, which are probably not the same as the signals from a speaker. If I had to guess, the pickup would be taking the signals from each string individually, while the speaker from this kid's toy is taking the entire sound as a whole.

It's also possible that the teeny-tiny magnet in that speaker just isn't strong enough to send a strong signal. I'm not sure what you could do about this.
