Pi for education - Raspberry Pi Q&A, Help & Troubleshooting

Hey guys,
I want to get my son involved with programming/linux/how things work! Does the Pi actually do this, or is it just a bit of a toy?
Also, because its so cheap, do you think its worthwhile putting them in schools to teach EVERYONE how things work?

The Pi does it all ! You have the Linux to tinker with, and Python og whichever you choose for "advanced programming". For the young learners there's Scratch programming. Its a graphical programming language. And with the GPIO port you can connect a diode for example, and program it to flash or light up depending on you program or choice.
It is a good and simple platform to learn programming on since you have all the choices in languages, but also the GPIO port for seeing a result on.

yeah, ive done some fiddling around with it. i want them to make a version that is EVEN harder to use out of the box. the stuff that comes straight out of the box is often just used as a cheap media player......

Any Laptop

Alright guys. I'm getting a new laptop for school next year, and I can get basically anything that I want. I don't really want a Mac, because quite honestly, I'd end up installing Windows on it and never using the iOS. So, what computer would you choose (laptop, anyone you want!). I've been looking at The Lenovo IdeaPad Y540 with the RapidDrive. Any suggestions?
toshiba satellite laptops are good. my sister has one. it's good, and not too expensive.

Go to the dell website and customize a laptop to whatever you want, you know, choose your own: processor, ram, hardrive space, graphics card etc.
I customized an inspiron 1525 a whil back and its running nicely
how about the best of both worlds , getting a macbook to show around and get the honeys in school , and having it dual boot windows at home to get some work done (when nobody sees you , ofc)
I use Lenovo Thinkpads normally. They are awesome. I really like their customer service. It's really IBM, but they are very patient and knowledgeable.
Well, you'd never use iOS on a Mac anyways, since iOS doesn't run on Macs (except in the emulator as part of the iOS SDK).
It is all about what you need. I'd get a Dell and run Ubuntu on it if I wasn't relying on certain Mac OS X software. Oh wait, I have a Dell running Ubuntu that I use a lot, in addition to my MacBook Pro.
The problem is you don't specify your needs at all, there is no best computer. I love my MacBook Pro and I love my Dell. And I'd happily recommend either of them to you, or several other machines - depending on your needs. So, what do you need?
I'd advise against getting a Dell Inspiron. There's a design flaw in the hinge where the case starts to spread apart; my girlfriend, mother, and roommate all have the problem and it started just after a year of owning their laptops. If you're already looking at Lenovo and you really can "get pretty much whatever you want" I'd suggest looking at a ThinkPad, the build quality is much better than the IdeaPads.
What are you exactly planning to do with the laptop?
You might need extra graphics muscle for vid editing our gaming.
Go for something with a sandy bridge. I'll be somewhat futureproof.

Seconded.
Or you can just boot Windows and say;
"I REALLY love the hardware, but Mac is sooooo last picosecond ago."
Otherwise, go for an ultraportable.

Have you ever actually USED OS X? Like I said, a computer is a tool. OS X provides the core foundation to do things Windows users can only dream of. Want me to blow your mind? I can show you videowall and blended projector setups running all in software (plus some Matrox TripleHead2Go's) doing things that required thousands of dollars worth of video processing hardware five years ago.
Granted, that's a rare application, but the same benefits apply to lower-level programs too. Mac OS has had true, full system-wide color management since the first OS X release. Windows? Their new, much-touted color management is about on the same level as Mac OS 9 was - 11 years ago.
Apple has done a great job providing creative professionals with an amazing platform. Sadly, it seems like they're abandoning us in favor of the content consumers and iOS. We shall see. But for right now, it's the best thing out there for the needs of many creative professionals.

Have you ever actually USED Windows 7? Like I said, a computer is a tool. Windows 7 provides the core foundation to do things Mac users can only dream of. Want me to blow your mind? I can show you 16xAA and 4xAF graphics on SIX monitors (plus some sick DirectX 11 tessellation) doing things that required thousands of dollars worth of Mac hardware five months ago.
Granted, that's a common application, but the same benefits apply to lower-level programs too. Windows 7 has true 3d games since its release. Mac? Their new, much-touted app store is probably 4 to 5 years behind.
Microsoft/AMD/ATI/NVidia/Intel has done a great job providing gamers with an amazing platform. Sadly, it seems like they're abandoning us in favor of the content consumers and consoles. We shall see. But for right now, it's the best thing out there for the needs of many gamers.
FTFY.
Um, not sure if it was your intent, but you only proved my point. Different uses need different tools. We've got Windows 7 sitting and running up at the church on two machines that have replaced our sound boards (both front of house and monitor mix) and much of our effects and processing gear. Software Audio Console by RML Labs. Great product, and runs fantastically well on Windows 7. The developer is a bit of a nut, and he himself is always complaining about what Microsoft does poorly in Windows (especially in regards to memory management, which he notes is tuned more towards most processing power, not lowest latency like one desires in a live audio application). Regardless, he's managed to get Windows down to a few milliseconds of latency, and he has the whole setup working very, very well.
So, you proved my point. Windows 7 is a great gaming OS. I never said it wasn't There's a lot more to this world than games, but if games are what you want, the Windows 7 is where it's at - though OS X is catching up. It's definitely had "true 3D" since release. Right now the two big issues are drivers that aren't really tweak-able - and tuned more towards rendering accuracy than performance; and the actual support of developers (though both have improved a lot in the last year).

I'm just trying to say beauty is in the eye of the beholder. Whatever platform that you use, as long as you are happy with it. I will not begrudge you if you decide to buy a Mac for legitimate reasons (graphics editing, etc.), but a Windows PC for me is a much better deal. Maybe its because I've grown up around Windows, so I'll never get the "need" for an overpriced and underspec'd computer.
And, yes, my PC is kinda heavily modified
Glad we could find a middle ground
Get a Macbook Pro, At least you wouldn't be getting those annoying updates and useless Norton Anti-virus notification. I been a pc user for more than 10 years and Os X is really not bad like people make it out to be.

I think if you'd shop it, you'd find Macs aren't bad for what you're getting, price wise. There are things that have value people don't mention. Things like the glass screen on laptops (hard to damage and easy to clean - sadly, also REALLY bad glare) and the large full-multitouch glass trackpad... it's a joy to use, easy and fast.
As for the desktops, Mac Pros are crazy pricey at first glance. But when you look closer, they're using server (Xeon) processors and server-grade components. Which makes almost no difference in performance, but it does legitimately add a fortune to the cost. Apple needs a true desktop machine. But if you compare it to other machines using the same components, pricing is similar or better.
The big thing is that Apple has no low-end, cheap-built, high-performance machines. Their machines are all made THEIR WAY. No choices. 1984 style, even. I do not like that, but when looked at in the broader market, it's not so bad - Macs are one of many choices to find the best tool for each job. Windows is also one of many choices. I spend much of my time on a Dell in Linux
BTW, I wasn't even talking graphics editing. Though the color management engine makes Macs great for that. Next time you go to a concert and see walls of video screens behind the stage and stuff like that, and you assume there's a ton of fancy video gear, there might not be. The software exists, on Mac OS X, to do that all in software today. And the software exists, on Windows, to mix sound all in software, today. And the results, in both cases, are as good as traditional hardware solutions.
Sorry I have't posted back guys. But I ended up ordering:
Toshiba Portege r700
Windows 7 Pro 64 bit
Intel i7 @ 2.67 GHz
4 GB DDR2
120 GB SSD
Fingerprint Scanner
HDMI Out
13.3 inch widescreen
The SSD and DDR2 was important to me since I will be a computer engineering student. I love it. Fast, extremely thin (for all the guts) and just as light as my girlfriends MB Air.
Thanks for your help.

Sounds like a nice machine, but I question why you wanted DDR2, and not DDR3. I'm just a noob though.
ASUS G51J works GREAT for gaming and school

Ubuntu Home Edition

ButterflyCommunity​
Couple of friends and me came to an idea of making our own distribution.Our idea is to make Linux distribution suitable for not so geeky people(eg.older people like your mom or dad,or young people like children in elementray scholl).Thats how we started making Ubuntu Home Edition.Linux distribution based on Ubuntu that everyone can use.Theres no commom unnecesary problems that cause headache to your family.
We made our own update menager that allows them to update specific apps at time they choose.In addition to that UHE has enabled optition to clean it self every week,by "clean" i mean it cleans cache,history etc.
UHE comes preinstalled with all the software they could ever nedd browser,mail client,office client etc.
We think that UHE will be perfect solution for "familiy administrators",they will be able to setup UHE for their familiy,and just foget about it,no worry about av updates,product activations,maintaining computer.
I want to hear you opinion and recomondations as well as critics.
Official website
All the tips post here or send them to our tip email(find it under suppoet section on website),please dont PM for that reason.
Sounds like a good idea. I have family members, mostly older that only want internet and email. Ubuntu with Firefox/Chromium and Thunderbird would be all they need. How does this handle OS and software updates? If its something that can be kept up to date with little computer knowledge then this may be worth it.
Looks like it would be a pretty good idea.
I love the idea of it but your link is broken or it loads up a blank page with one icon on it so I can't really tell you much else about what I think. It's hard to get people to get started with linux but I think it's been getting easier than it used to be thanks to graphical installers. Just make sure to make the installer idiot proof and give it wide compatibility with some extra drivers for all those older people using crazy hardware and I think it'd be great! Keep it open source and offer the source everyone loves that. Uhm.... don't charge money? hehehe
All of my work is opensource,becaouse i belive that opensource is future.And yes there are extra drivers and extra languages build in.

[Q] Developing apps and compiling roms on raspi

I'm thinking of buying a raspberry pi for learning programming and I wonder if it is possible to develop android apps and roms on the raspberry pi.
Probably the device is too weak but I thought that of running Quake 3 on the raspi, too.
So I am asking you if anyone has experiences with developing Android on the raspberry pi.
I hope you can help me.
Start here: http://www.amazon.co.uk/Raspberry-Pi-In-Easy-Steps/dp/1840785810
Doesnt say anything about Android on the site.
Android will most likely never run on pi. As far as compiling android roms on the Linux platform. Feasible at best, with half gig ram I think it would take some time to compile, but I have no experience with that. What i have experienced.... nothing on pi is fast
OK, thanks. I think I will do a little Python programming and maybe a lego robot. Do you have suggestions what to do with GPIO exept from led?
check out the projects thread, I have one to run my charcoal smoker, reads three meats pid controller runs a fan to stoke the coals. I have one to run my sprinkler system in my garden, 4 zones on a timer,I want to add a moisture sensor to that and automate it
Either by swapping on a cheap USB 3.0 drive or by waiting a little longer, the RasPi should make a dirt-cheap nightly build server! Imagine compiling CyanogenMod overnight without spending more than 2W of power! And even faster by overclocking to 1GHz with a 3$ heatsink kit! :victory:

About me

I'm someone who likes to get the best out of my computer hardware. I love Linux mint, and still have a Windows computer. I line Android phones, and tablets, but sometimes the software goes unsupported after some time and then drastic steps must be taken to keep using the hardware. That is my interest in xda. Looking forward to modding my Nvidia shield tablet k1. Cheers!, B
Linux Mint brings you lots of pleasure. I really don't understand why Windows keeps its popular position. Hope you'll have a nice time here on XDA. It brings you to all parts of the world with extreme expertise.
Just learn how to use it .....
Enjoy a nice stay in a wonderful new week

about me - dilemma to switch to kotlin or use frameworks (Any advice Appreciated)

I'm Computer Science Student <+Tech Enthusiast> Currently I'm Working on a app Using Kivy (Python Framework) initially it is to help me Find Music Scale Notes On guitar Fretboard with custom Tunings, + A guitar Tuner ,Metronome +simple drum and other audio simple content files to create Back tracks Jams.. Currently i have written Python Script (in progress) now Learning more about KIVY FOR GUI..
First i was about to switch to Kotlin for Android Dev (I know C and thought as they say learning First language is the difficuilt switching to another is just about syntax) and as AI And Machine Learning are hot trending topics everyone talking about but less familiar with it coz the perception of Terminator... I Continuing practicing improving Python skills .. As of Android (I just know it works on Linux Kernel and I'm using Debian Distro for a while now ) I'm Studying Networking and Trying to learn Assembly and compilers
I recently lost Samsung Note10+ because i wasn't familier with it on lower level Thought i might brick it And gave it to Someone with Shop AND HE DID THAT FOR ME ..Well he took me back to base Varient With stone age Features and me messing with system apps ruined it.. So I'm Hopefull i will Learn about this Machine Here And Might of some use here..
Great Platform ( XDA ) Great Community
