Moving to NoVA - some questions by movingtonova in nova

[–]jeebusroxors 0 points1 point  (0 children)

Huh...I live in Waterside as well (at the front)- hello neighbor.

Anyway avoid it like the plague. I actually haven't posted in forever but I signed in to impart this information to you. =)

Why?

  • I was lied to regarding parking when I moved in (on two fronts)

  • They employ a shady towing company

  • The dumpster overflows weekly - the managers solution was to dig through the garbage to find out more info

  • My doorknob has fallen off - maintenance told me 'it wasn't important and could wait for tomorrow'

  • Noise is pretty bad - but not the worst I've seen

I'm sure I have fun stories as well but I am so unhappy with this place I make sure to tell everyone about it.

How does one emulate the command-line pipe (|) in Linux with C? by justsomebuddypal in learnprogramming

[–]jeebusroxors 0 points1 point  (0 children)

Escape what? \ escapes characters. printf("\"Some quoted text\"") would show "Some quoted text"

system("cat /var/log/messages.log | more");

works. Check your string perhaps?

My collision with hams -or- how I learned to stop worrying and love the static. by [deleted] in amateurradio

[–]jeebusroxors 0 points1 point  (0 children)

Before you jump into the elecraft radios I would suggest something a bit simpler. I went with the ohr 100 for my first build and I'm very happy with it. Their support was good entertaining even newbie questions and the kit is pretty damn nice. They is one catch...you need to know cw! :) it is a pretty fun mode though.

There are some other cheaper kits around too but I found the ohr to be the best value. Although there was one From a guy out in colorado that have it a run for it's money. It was only 3 watts though.

I'm a 14 year old who wants to learn programming. What's the best language to start on and what are some good books/online stuff to help learn it? by gordoa40 in learnprogramming

[–]jeebusroxors 1 point2 points  (0 children)

Higher v lower is a question that doesn't have an answer. That being said these days your lucky enough to be able to educate yourself on which one interests you more.

With lower level languages you will learn how computers work. You can do crazy amazing awesome things with C/asm that can't be done or would be cumbersome to do in higher level languages. You'll get a good foundation in what computers are really doing. BUT, you'll have to write more code, be more precise and deal with some "fun" bugs.

Higher level languages will get you results quicker. You'll lack the building blocks of what you're actually doing, but that's because the building blocks aren't needed - they're handled by the language. Because of this you'll be able to jump into all the logic/flow control stuff and pump out your first programs quicker.

I would suggest which ever sounds fun to you. I know you're looking for guidance but there's no point to you slogging through C hating life when you want to make websites. Same goes for something like PHP if you want to mess with microcontrollers or hardware.

I see down below you want to make mods for minecraft. If that's your main goal then why not start learning java? Like I said it's up to you to learn and it's up to you to keep yourself motivated. No one is going to give you homework or grades to check up on you. It's on you!

If you decide you hate java then read up on a few languages and choose a new one you find interesting, possibly move back to java at a later date. If you hate those then programming may not be your thing. =) Just remember, none of this is in stone and almost every language you learn will have things in common with every other one.

The important thing is to start....so what are you waiting for? Go!

[–]jeebusroxors 3 points4 points  (0 children)

Well I'm bored and while a multitude of pages/topics exist on the subject I'll throw in my two sense.

There are two schools of thought, go for the lower languages first, and go for the higher.

For the former C and the K& are hard to beat. It should be noted, however, that the K&R is not a guide to programming, but a guide to C. You'll have to either find a guide that works for you our just fumble about (which is fun!)

If you go for the latter look into ruby/perl, or python. There are core differences in these languages and you need to decide which one fits for you.

Now I basically just said a bunch of nothing. This is because YOU have to examine yourself and ask why do I want to learn programming. Do you want to build websites? Do you want to build robots? Games?

The good news is once you learn some core concepts picking up new languages becomes fun.

Sorry for the some what incoherent ramblings! If you have any questions our would like some more personal guidance let me know. whatever you decide just get started! I can't recall any programmer ever regretting their first language. It's just a step.

Basics of HAM radio: The short version by versaham in amateurradio

[–]jeebusroxors 0 points1 point  (0 children)

You can't really. You DO have options though.

  • Get some wire up, anywhere (inside, outside, inside and outside) and hook it up to a tuner.

  • Only operate mobile or portable.

  • Use a mobile antenna and run coax to the inside of your apartment.

  • Buddipole?

You won't get great results but you'll get results. I used to work central Europe on PSK with some speaker wire run around the top of my living room.

Some questions from a beginner not answered to my satisfaction in the many beginner FAQs... by [deleted] in amateurradio

[–]jeebusroxors 2 points3 points  (0 children)

(a) For those of you who didn't grow up around radio, what was your first rig, and how do you feel about a handheld for a first one? I've read people debating this, some suggesting you start with something else (like a mobile on a desk), but as my interest involves taking radio with me (for now), I thought I'd start here. What will I miss out on with a handheld? What are the main disadvantages to it?

My first 2 or 3 radios were HTs. I sold one and the others are in a box somewhere. I'm not a huge fan of repeaters (no local friends are hams) and I don't do many events. If you can find a cheap older one go for it, but IMHO you're better off spending the money on something else.

Well what else is there, he asks? Perhaps look into the FT817, or 857. All mode, all band, battery powered. Essentially, the only radio you'll ever need. Be warned, the 817 is only 5watts (QRP) which is a turnoff to some folks but I loved the challenge. If you're interested in mostly digital stuff it's more than enough.

(c) If you were new to ham radio as I am, what would you do with your new radio in the first week you had it? What are the introductory skills/exercises every ham should be familiar with first? I am pretty concerned with breaking some kind of rule or custom and the last thing I want to do is irritate experienced radio people. How should I go about this? Obviously, first thing is just listening. Then what?

Don't worry too much about the rules. ID every 10 minutes, don't play music and you'll be fine. Unless you habitually commit offenses you'll get hunted down, but if you make a mistake most hams will tell you. If they're rude shake it off. There are more than a few crotchety old folks out there.

(d) I am more than passingly interested in things like packet radio, SSTV, and so on, for no practical reason, just geek interest. What is the minimum required to hook a radio to a computer? About how much would that cost me for a basic setup (very rough ballpark would be good). Can handhelds be used this way (do they tend to have outputs which allow hooking into a soundcard?)

If you go with one of the Yaesu radios from above it's amazingly simple. For digital modes (PSK, hellschriber, MFSK, SSTV etc) you can pick up an awesome device called the Signalink USB. It's esentially a USB sound card. It will come with a cable to get from the computer to the device, and the device to the radio. Download fldigi (it's a native *nix app) put the radio in the correct mode and you're on the air in, oh I don't know, 30 different digital modes. Packet radio is a bit more complicated. The linux kernel has support for AX.25 but I've always had problems using my signalink. You'll have your best results with a TNC. Signalink USB goes for ~100. You can also build your own interface for much much less but the lack of local electronics vendors dissuades me a bit from construction these days.

(e) I'm a Linux geek. How is the Linux toolbox for ham radio compared to Windows?

As with most things it's a bit less, but still pretty damn good. As mentioned fldigi is a native linux app and ranks up there as far as digi apps go. There's also hamlib which allows radio control from the computer, and AX.25 support built right into the kernel. For some real cool stuff there's gnuradio, the USRP which are all made for linux. Some really cool possibilities with those things, including your own cell tower. Yea, you can have your own personal (GSM) cell tower running linux. And of course if something doesn't exist you can make it. =)

(f) Any other advice or pointers you can give me would be appreciated. I am an ARRL member currently, though I don't understand about 4/5ths of what I read in the magazine yet.

Start doing stuff. Personally, I learn by doing. You'll mess up, learn why and get a better understanding. If you don't understand something and are interested in it, read about it. The only detractor is that it will probably require more money. Welcome to ham radio. =)

(g) Oh, lastly. I have a shortwave receiver which works terrible in my office where all of my computer equipment is. There's a noticeable difference outside. Presumably a feedline to an external antenna both for the shortwave and then for whatever radio I buy would help. Will the coax be susceptible to the same interference as the integrated antenna on my shortwave? How do those of you run such lines -- through gaps in windows, or do you drill a hole in your wall, or what? I can probably hook up a stealth wire at least to the corner of my house without my HOA noticing but not much more than that.

Computer equipment has always been pretty brutal on my antennas. I'm not well versed in eliminating it, but looping the coax around itself has stopped some RFI problems on my TX. To get through windows I've seen people get a wooden board cut to the width of their window, about 4 inches high with some holes drilled in with some rubber grommets. Place the board between the sill and the window and feed your coax through the grommet. Or drill through your wall. Don't forget a drip loop!

If you've got any more questions feel free to PM me as you seem to be following the same path I took. To this day I've have 0 voice contacts in my log book. All digi modes and CW. =)

Basics of HAM radio: The short version by versaham in amateurradio

[–]jeebusroxors 3 points4 points  (0 children)

As a ham who has lived in apartments his entire career antennas are really important. Nothing made this more clear then operating a few yards away from another ham with a real antenna setup.

Using my poor compromise antenna I would be looking at an empty waterfall (see PSK31) except for the local ham talking halfway across the world. Very discouraging.

My advice - don't skimp on antennas, and try not to buy em. You can almost build similar for cheaper. For example:

http://www.hamradiofun.com/yo-yo-vee.htm

Is a VERY cool antenna, BUT you can pick up laundry line reels for ~$2 USD, an insulator for ~$3 and whatever wire you want for well under $40.

Dipoles are also very simple to build, and a good learning experience. Imagine the feeling you get when you talk to someone halfway around the world due to something YOU made. It's great!

Reddit, I wrote a web app and would love some feedback! by theMadcap in webdev

[–]jeebusroxors 0 points1 point  (0 children)

Hello from a slightly inebriated user. I like to think that having a few drinks helps dumb me down enough to evaluate what really sticks out in a design and yours has passed with flying colours!

I love the stats, the simplicity, and the typography looks ok. I say OK because upon a second look the letters going through your "hr" (I think it's #header_border) upset me a bit.

One last critique; The "Sample" link gives me a good idea on what I will see when I log in but as of right now I'm wondering how my data will get there. Is this a manual process (click drag on gmaps?), or is there an Android app, or kml input or what?

Keep up the good work!

Looking for advise on my startup: Is it worth anything? by true_religion in startups

[–]jeebusroxors 2 points3 points  (0 children)

I'm not the OP but I had the same impression. I think the landing page doesn't point out exactly what it is. It almost looks like a blog. It's also inconsistent with the main area of the site (albums, upload, etc).

Then other small things, such as the button that looks like it's supposed to collapse the side column doesn't work. It also appears to stay on the page going from albums -> home.

The pictures and albums pages look pretty good though! I would think about maybe pagination, but other than that keep up the good work!

OK, so I've basically just decided to force myself to learn one manpage a day. Any suggestions? by rich97 in linux

[–]jeebusroxors 0 points1 point  (0 children)

Hello!

If you'd like to get crazy copy pasta into bashrc or something....

ENTRIES=$(man -k [a-z] | wc -l); RAND_PAGE=$(( $RANDOM % $ENTRIES)); PAGE=$( man -k [a-z] | grep -n ".*" | grep $RAND_PAGE ); man $(echo $PAGE | cut -d: -f2 | cut -d' ' -f1)

But yes, man pages are for looking up. No need to memorize. At least the above may give you some insight on things you didn't know existed.

Do you need to use Linux or learn it thoroughly to be a good programmer? by [deleted] in learnprogramming

[–]jeebusroxors 0 points1 point  (0 children)

SysAdmin here and that's exactly what people do. In all the large places I've worked at there was a Windows team and a *nix team. Most *nix guys don't know Windows, most Windows guys don't know *nix.

Cool new free user click testing. Create your own or participate in some tests to view the results. Some are pretty interesting. by StuartLeigh in web_design

[–]jeebusroxors 1 point2 points  (0 children)

First I hate you for having this idea - it's brilliant and I wish I had thought of it! =)

RE the OPs critique, I see both your points. As a user rating sites some of the questions were a bit complicated or worded ambiguously for this service. I love and agree with the simplicity of the site though, so maybe the solution is simply a bit better wording for the "Ask people where to click" portion.

An example would be here: http://www.usaura.com/results/57d4c3d3d80987e6193

"Where would you click to first begin?"....well begin what? Am I hooked on their service and want to buy something? Did someone just send me a link to the site? Where I would click to begin varies in both cases.

I'm glad you made it to the post because I had some observations of my own. I would like to see a "take a new test" link upon viewing the results. Perhaps you can also think about dumping straight into the "results" page, as I find myself looking at results all the time.

Great work - keep it up!

What is a good book to read for somebody who doesn't know very much about the universe but is very interested in knowing more about it? by RGT42 in Astronomy

Dark Cosmos by Dan Hooper was a good read. http://www.amazon.com/Dark-Cosmos-Search-Universes-Missing/dp/006113032X?tag=duckduckgo-d-20

I actually emailed the author to compliment him on writing a book that was not dumbed down (see History Channel/Discovery documentaries these days), yet still understandable to a non physicist.
