From the Foundations official downloads page here : https://www.raspberrypi.org/downloads/raspbian/ Texy Yay thank you for the link! but despite of the fact that Jessie is better for Qt, what are the differences between wheezy and jessie ? thx No difference really. It is just that they give a fancy...

The entire http://www.qlcplus.org suite is built using Qt5 on Wheezy. Works like a dream. Just for the records. I don't get it, with the link you posted, i should be able to build a qt5 project on raspbien wheezy ? ( and do you know where i can get raspbian wheezy or jessie btw ? ) Nope. Qt5 is doa...

Qt would work. It is C++ based, has widgets and uses ui files as layout managers. It is much heavier to use than the Python versions recommended in this thread. You may not have all the tools from the Qt5 package available as Raspberry Pi is kind of small computer to run big programs like the QtCrea...

If you intend to do this in C you could write pixels directly in the frame buffer. A tedious approach but doable. Have a looks at something similar http://stackoverflow.com/questions/4722301/writing-to-frame-buffer . Usually people use higher level languages where you can define widgets. In order to...

Imho programmers work with the units users are using. Tablets, phones, web comes to mind. At the place I work R&D is using Ubuntu in different flavours. We are also working on Windows for old end-of-life products. But all new stuff is either Debian, FPGA's or embedded Linux. It also shows in the com...

You could install ifmetric and set the wireless to "ifmetric wlan0 0". It then overrides the "ifmetric eth0 1".

karrika

If your eth0 does not provide internet you can delete the default route. In this way you get internet when connecting the wlan.

Code: Select all

auto eth0
iface eth0 inet dhcp
    post-up route del default dev $IFACE

This may not be what you want if you can have internet through the eth0 also.

Thanks for the thoughts about this matter. The helpdesk actually did what I wanted them to do at Sunday night around 8 PM. Fortunately my customers were also quality conscious and had a way to handle lack of critical services. So no harm was done. And I did file a customer complaint and wrote a feed...

to get the IP address of the local site i would use something like noip.com. Where they have an agent i can install and it will point the hostname (remotepi.noip.me) to it's current's public IP. Is there a way to get a screen sharing session over https or ssl? Thanks Sometimes I have to use https p...

At least the plane flies great.

For a VPN tunnel to work you need to have one IP address that is seen from home and from your friend. At this IP you run your server. Your friend can then connect to this IP with the RPi and the RPi gets a virtual address like 172.31.0.100. When you connect to the server you get another virtual addr...

That shield is for Arduino and so is the software. It seems to be open source so after a lot of work you may succeed in getting it to run on a Raspberry Pi. The question is just that why don't you run it on Arduino?

Linux offers something called CUPS for printing out things. I don't know how much is built in to raspbian. You could start by finding out if cups supports your printer. It has a configuration interface at http://localhost:631. You can set up new printers from that one. Since around 2009 cups has bee...

Nice :-) What's the white PCB at the back? any more photo's of how you put it together? The inside is just a PiZero and some wires. Not much to see here. It uses the analog pins for the monitor. The 12V power for the car monitor is also switched down to 5V for PiZero by TRS 1-2450 sitting next to t...

The problem is that these ancient connectors are no longer made. So I had to print one and build it from lots of safety pins. http://atariage.com/forums/uploads/monthly_08_2015/post-2099-0-13269800-1439892557.png That is a seriously clever design. Well done. I wish I had your hardware skills. Thank...

The white PCB on the back is an Atari Lynx cart slot. I use it for creating real carts for real Atari Lynx handheld consoles. You can also use it for reading original carts. https://s3.amazonaws.com/images.ecwid.com/images/7603030/333074431.jpg The cart itself is a 512k cart that you see with a 3D p...

Actually the hardware is less interesting than:
- Number of existing OS images (Raspbian, NOOBS, RetroPi)
- User forum
- Active user base
- Programming tools available
- Add on boards
- Price, long term availability

Writing programs for Atari Lynx and maintaining the developer tools for cc65 has been my hobby for years. Now as I got a brand new PiZero on MagPi cover it ended up to run my new gaming console. http://79.125.115.174/pics/PiZeroArcade.jpg The game Zarlor Mercenary has an original resolution of 160 x...

Don't forget to fill out the customer satisfaction survey, if they are big, they are probably certified for something, which means they are obliged to take feedback and demonstrate they take it seriously to keep their certification Their QA and audit functions will be interested if you want to give...

I have just spent 48+ hours trying to get help from a help desk of a very large organisation. I know exactly what is wrong. I know exactly what they need to do because I found a bug in their database logic. But I cannot get in touch with anybody capable of doing what needs to be done. There is TONs ...

You could add to your client.conf a few more settings for debugging this. status openvpn-status.log log openvpn.log log-append openvpn.log # Set log file verbosity. verb 4 It may also be a good idea to install tcpdump and have a look if the packets on 1194 are going in and out.

There is quite a lot information about interfacing at the Raspberry Pi main site. Perhaps you could glance through the articles in https://www.raspberrypi.org/resources/learn/.

Actually, the C# compiler, runtime, and libraries have been open-sourced by Microsoft under the Roslyn .NET Compiler Platform as part of their .NET Core project ... and it's hosted on ... are you ready for this?

the obvious absence of Microsoft Visual Python from their product lineup as a strong indicator as to whether the Python API will be in Minecraft: The Edocalypse Edition :lol: . I would be willing to bet a considerable sum that something like a C# API might appear, though. That is not nice. As a fir...
