That is the crux of it. We're doing it as a pilot program. It's all proof of concept right now. There's no guarantee that this'll be the next big thing. So far, the DJI Phantom 4 Pro has performed wonderfully. The software that we use to map the flight path is a bit glitchy sometimes, but can usually be fixed easily. We've got a guy who has passed the FAA cert for commercial drone flight, and he's the one going out and getting the images. My main thing was that it would be really awesome if I could go to my boss and show him it was feasible to build a drone that would compete with the DJI for the same amount or slightly less. The more I look at it, the more I think that the tech isn't ready yet.

Sony cameras? The sensors I've been looking at are small ultrasonic rangefinders. Did you see a post where someone else was using cameras as a sensor suite?

Wow. That's a hell of a price drop. Makes me wonder if they're coming out with some new shiny soon?

I work for an insurance company that's trying to keep adjusters from falling off of buildings by looking at the feasibility of using drones to map roof claims. As a proof of concept, my boss bought a $1500 DJI Phantom 4 Pro. He's asked me to look into building drones as a feasible way to keep costs down. I've been researching it, but I keep coming against conflicting data. I was looking at using the following list as a preliminary build, and kept seeing people who have a similar build saying that everything works great and that it flies beautifully. But when I run the math (using a SWAG for the mass of some of the items), it's a bumblebee. It's too heavy to fly, it will only fly for maybe 6-8 minutes, etc. I'll grant that I'm looking at doing some things that probably haven't really been done as much in home builds of aerial photography drones, but I need to beat a Phantom 4 in price and ability if possible, which is no mean feat.

I'm starting a homelab with what modest means I have available. I've started setting up an i5 Intel NUC with Proxmox so that I can virtualize a few small appliances. I have a really small network of maybe 10 devices on a good day, so I think I can get away with what I want to do. I'm wanting to set it up so that I have a pfSense firewall appliance, and a *nix distro running my DNS DHCP server. Both of these roles are relatively light for a NUC running on an i5 with 16GB of RAM. What I would like to know is if anyone else has travelled this path before me, and if so, how did it turn out?

I just found out about Shenzhen I/O. You design the circuit, then write the assembly to create your own computer inside your computer. Something something meta... http://store.steampowered.com/app/504210/

Don't forget your quotes around your strings. I know it's standard to C++ and Javascript, but I work with a guy who beat his head against the desk for 6 hours looking for the source of the missing ; before statement, and it turned out that he hadn't put quotes around his string. As far as debugging, I haven't done with just javascript, but when mixing PHP, Javascript, and HTML, I like to use the Firebug extension for Firefox. I've been able to track down some issues that just don't show up otherwise, and it especially helps with the javascript, assuming it's in a .js file and NOT in <script> tags. That's my .02 cents, YMMV, and I approve this message.

While Codecademy is a good start, you may also want to check out your local library. They'll likely have some books on programming, usually C++, C, and Java if nothing else. Having multiple resources usually helps when trying to learn coding.

As far as a first language, I would say C or maybe C++. But I would recommend learning VB, Java, C#, C++, Python, Assembly, basically anything you can get your hands on. While there are differences, there are a lot of similarities that may help you understand something in one language that's escaping you in another.

Hacknet is pretty cool. I also like Hacker Evolution, and TIS-100. I think that TIS-100 is a great assembly based sim.

If I didn't need Visual Studio Enterprise for school, I'd remove Windows 10 from all my devices and just use Linux, probably Arch. Since I need it, and I need it to perform quickly, I'm stuck with Microshaft Winblows.

With Metal Gear Solid V: The Phantom Pain already out, I was wondering if there's anyone else here as enamored by the story as I am. It's amazing just how far things have come from Metal Gear back in 1987. We have gone from a game that took about an two hours to beat, to a 40+ hour game experience that still manages to embrace a well rounded story, an enjoyable game play experience, and give us an open world to explore. I gladly tip my hat to Hideo Kojima and his hard working team.

Haven't done it with Kali, but with Ubuntu, it broke grub, but that was easy to fix with a live CD/USB. Other than that, Windows 10 doesn't interact or affect it at all.

Hell, I have an ASUS X550 with an i3, and that works wonderfully with every *nix distro I've tried. I'm currently running Ubuntu, and after bootup, I'm using 450MB of RAM, 3% CPU, and it honestly does everything I need it to. It's not expensive, and it works very well for the cost. But that's just my two cents.

Since I haven't bothered to post one before this... Favourite game: Any of the Metal Gear Solid Series, but MGS3 has a special place in my heart. Favourite OS: Arch Linux Favourite console: Other than PC, I enjoy playing my PS3. Nationality: American Accent: Only if I'm trying. Sex: Male Race: White Height: Tall enough Favourite band: Rush Favourite book: Time Enough for Love Favourite author: Robert Heinlein Favourite movie: Back to The Future 2 Favourite TV Show: Firefly Favourite actor: Nathan Fillion Other hobbies: I build and play guitars, and pretty much anything that requires use of the hands and mind. Occupation: Tech Support Representative, which is a really boring way of saying that I'm the idiot on the other end of the line when someone calls in about their baby monitor, business phone, credit line, electric car charger, etc.

So, after all the crap that's gone down with Flash, I've decided to uninstall it from every computer I use. I went to watch Mr. Robot on USA's website, and what prompt do I get? Oops! Looks like you need to upgrade your Flash Player. For all the awesome stuff the show has to offer, for them to not be among the first to rid themselves of Flash is somewhat surprising, and a bit disappointing. SMH

They're also working on getting Unity up and running for Linux. Link here.

The live install is running entirely in RAM, and isn't really using the USB other than to boot the OS. The persistent install is actually using the USB drive as a 'hard drive' to save settings and files you create. As mentioned above by Cooper, USB isn't really meant for this. The best way to speed up a persistent install is to use an actual hard drive, whether it's solid state or magnetic.

Not a problem. If you look at it, this isn't to record desktop. What I posted allows you to use the webcam if you select /dev/video0. At least, I was able to access my webcam from it. The name of the thread is Use VLC to capture video from your webcam to a file.

So THAT'S why they make those. I always wondered what they were useful for.

I'm not familiar with cheese or guvcview, but have you tried using VLC? It can record video in addition to showing it. The full thread on the ubuntu forums can be found at http://ubuntuforums.org/showthread.php?t=143732 if needed. Here's the most relevant part. You can change the encoding as needed. Open VLC File--> OPen capture device Go to Video4Linux tab Specify your video device name (mine was /dev/video0) (My webcam audio doesn't work, so I left audio device as it is) Norm: Automatic Check "stream output" box Click settings Specify a filename (make sure you have write permissions there - usually a file on desktop or home directory is the best bet) Unselect "dump raw input" (it must reamain empty) Encapsulation method: MPEG1 Video codec: mp1v Audio codec: mpga "select all elementary streams" should remain empty. Press OK Press OK Now press PLAY button on VLC. The video should start recording. You can check this while VLC is recording video by right clicking on the recording file and selecting properties (it will show increasing file size). I was able to do this pretty quickly and easily. Hope this helps.

I thought it was. I keep finding stuck pixels in the skybox when I look up at night. Or maybe those are stars.

Me too. I like the way that some other forums do it. If you are looking for something, you put WTB at the beginning of your post. If you actually have a product or service to sell, you put WTS. If you're looking to barter with someone, you put WTT. It's clear, straightforward, and keeps things like this from happening, especially if your moderators are willing to lay down the ban hammer.

What do you mean, Hackers isn't realisitc? Am I the only one that has a projector shine what's on the screen right in my face to where I can't quite make out the image on the monitor? Next, you're gonna say that The Matrix is fake too.

I used to work for a school district as a tech. I mainly worked on desktops, laptops, printers, and the occasional networking job. One day, I get a call from the teacher who runs the computer class for the high school, we'll call her Ms. Atkins. (All names used are fictional to protect the guilty parties.) The following is our conversation. Ms. Atkins: "My computer just suddenly shut down, and won't power back up, no matter what I do." *My first thought is that her surge protector is on her desk, next to the PC, and the cable hangs down right about where her feet go when sitting* Me: "Have you checked to make sure it's plugged in?" Ms. Atkins: SOUNDS LIKE SHE'S MOVING TO LOOK, "Yep, it's plugged in." *I know she hasn't touched the wire at all. She just looked to see if it's there.* Me: "Okay. I need to know if it's a J847 cable or the P382 cable. The difference between them is that the J847 has 3 holes, and the P382 only has 2." Ms. Atkins: REMOVING POWER PLUG, "It's the J8 whatever you said. It's got 3." Me: "Okay. Go ahead and plug it back in as tight as possible." Ms. Atkins: "Alright." PLUGS CORD BACK IN. *I count to 3 Mississippi in my head, then tell her to press the power button* Ms. Atkins: "OH MY GOD! IT'S WORKING AGAIN!" To this day, I don't think she caught on that the cord was loose, and that she plugged it back in.
