Is there another way that the bad guys can get in by hitting the environment? Variables such as IFS and ENV can cause shells to misbehave. LD_LIBRARY_PATH and LD_PRELOAD can make any program load with additional code added. There is special handling for setuid programs in shells and in ld-linux, ju...

Note, BTW, that even if you have changed pi's pw, running this script still takes some time; I can see that it takes longer to login than it used to. Amusingly, it does all the slow stuff before the test for sshd that inhibits the warning. (Is it a defect that it does not check whether sshd accepts...

The problem is that system() involves a shell, and the shell detects that it is running setuid (real user not equal to effective user) and drops privileges. You could add a setreuid(0,0) to your program to defeat the test, but that is very dangerous. By setting environment variables, it is quite lik...

We have a responsibility to protect our users, and the combination of a known password and an open SSH port is an accident waiting to happen. The majority of Pi users won't even know what SSH is, so disabling it by default is reasonable - can you think of another OS for non-Power Users which enable...

# Nuke it apt-get --purge remove $p "Nuke it" seems correct. I tested your procedure on one of my Raspbian systems, which was recently dist-upgraded. It wanted to remove 1448 packages, including such gems as apt, bash, dash, dpkg, libc6, and mount, without which the system would neither boot nor be...

-Wconversion will warn about dropping the imaginary part from a complex type. It may be surprising that that is not included in -Wall or -Wextra. I am not too concerned about the compiler failing to detect logic errors, however. I do think that accepting a possible typo as a barely-useful extension ...

Ouch!

I am going to be using "gcc -pedantic" in future.

tScreen[1] = startNewTerminalScreen(800, 600); This seems to be the line that requires copying a structure. (Removing the call to tprint later may mask the problem simply because it allows the optimizer to eliminate the variable whose address is no longer taken.) If startNewTerminalScreen took a po...

If you switch to the text console with Ctrl+Alt+F2, are you seeing the correct (fr) layout there?

jojopi

The fact that you had to resort to the LXDE method suggests that your attempt using raspi-config did not succeed. It is correct that the GUI settings only affect the current user. For security reasons the console and login manager will use the system default layout, which must be set using "sudo ras...

The reference to memcpy is in the function drawLineC. I do not believe you have shown us the piece of code in question. It will be something that copies or initializes a structure, not merely takes its address. You may be able to avoid the copy. Alternatively you can provide your own memcpy implemen...

You can enable this behaviour in Raspbian: sudo apt-get update sudo apt-get install command-not-found sudo update-command-not-found (Then you may need to log in again to initialize your shell's handler.) Under the bonnet, this sets up the "apt-file" package, which actually knows a lot more than just...

What is the problem you are referring to? And if it is a kernel issue, then how does it relate to systemd?

The Pi is sending "á" with UTF-8 (Unicode) encoding, but something is interpreting it as ISO-8859-1 "Ã¡".

Are you connecting remotely? You need to configure the client system for UTF-8. For PuTTY: http://thegreyblog.blogspot.co.uk/2009/ ... utf-8.html

Why this? It seems both uglier and less efficient than the standard:

Some of them will produce a -1 for true, some will produce a 1 for true, and at least three of them produced a 32767 (which is 0x7FFF = 0b0111111111111111). So there is not a constant for the result of TRUE, it is compiler dependent (unless it is a part of the C11 standard, as most compilers are st...

Your original example used a struct that mirrored the icon block argument to RISC OS system call WIMP_CreateIcon.

Are you now claiming that you "always" translate your non-C++ to C on an Atari platform, prior to compiling it on RISC OS?

It is possible to install Debian wheezy armel (soft float). That was fully supported at one time. The Pi3 can also run Debian wheezy armhf. The author clearly means Raspbian wheezy, though, and the full blog posts do state that. You should probably start with Raspbian jessie . You will get better he...

I have a micro controller sending the alphabet one letter a second. My laptop with minicom works fine but when I use a Pi3 with Jessie and /dev/ttyS0 the pi seems to miss a lot of data. Out of interest, how were you connecting the 3.3V micro to the laptop, and did you try the same method with the P...

Although the files appear to represent a nine day period, the directory listing shows that they are all dated Nov 17. It is correct that nothing happens.

Okay, I see your point. Attempting to configure boot to desktop using raspi-config in a Lite image of course fails. During the failure it recommends the command "sudo apt-get install lightdm". That command is sufficient to allow raspi-config to configure the boot mode, but it is not sufficient to ma...
