Debian 8 GUI does not accept raspberry as the password which leaves you in a loop of incorrect credentials, with no way to recover. If you see a message such as "incorrect password", then your credentials are being rejected. Otherwise the password is correct, but the GUI is failing to launch. There...

IOError: [Errno 2] No such file or directory: '/mnt/NAS_A/Mongo_TemperatureLogs/MongoTempLog_24h.2016-11-08.tab' Doesn't seem right that "w" would trigger such an error unless there were something wrong with the rest of the URL path. Exactly. Neither "w" nor "a" require the file already to exist. (...

/dev/mmcblk0p2: Superblock last mount time (...) is in the future /dev/mmcblk0p2: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY (i.e., without -a or -p option) fsck died with exit status 4 An automatic file system check failed! Now I am even more suspicious that you are running wheezy. If fsck dies o...

Next time I try to boot the fsck during boot fails with "Superblock last mount time (..., now ...) is in the future" What else does it say? That particular error is not considered an unexpected inconsistency. It should be fixed in preen mode without manual intervention. Nov 10 14:17:06 raspberrypi ...

Raspbian Light, which should be called Raspbian Heavy without GUI. Or "Bloaty McBloatface"? I have even done the RAM disk only thing with Linux, and it works great as long as you have at least 128MB of RAM total (give 100MB to the RAM Disk so you have some work space, and have a full 28MB of system...

In the simple editor in my Raspberry Pi3 the cursor doesn't care to sens the spaces (or other special characters) so I need to be very careful where I place the cursor before I press the left button. In most applications, to select a word you can double click it. To select a phrase, double click on...

RISC OS on the other hand has a much caching system I suppose you have missed out the word "simpler", but perhaps "more antiquated" would be truer. Like your unsubstantiated claims that Linux programmers use bubble sort and linear search, the idea that demand paged memory is a "well known issue" is...

I saw nothing to suggest it was not supported. Its simply a range of numbers Whenever a program accepts some numeric parameter there will inevitably be both a minimum and maximum value that are allowed. The documentation says "Note: you cannot currently create a rule with a recharge time greater th...

I cant find anything to suggest a limit of 1/day is illegal. Is this a bug? Did you find anything that says it is supported? One packet per day strikes me as such a ridiculously low average that you might as well drop the traffic or logs altogether. It is a good idea to run "dmesg" after a system c...

There is no different ANSI C99 versus ISO C99. ANSI sells the international standard, now properly INCITS/ISO/IEC 9899-1999 (R2005). Yes, you can still use old-style function declarations if for some reason you need compatibility with 28-year-old compilers. But then it is your responsibility to pass...

echo HELLO > /proc/$(pidof cat)/fd/0 If you test that with anything other than cat, you will see it is not sending input to the program at all. It is just sending output to the terminal the program happens to be running on. I have never encountered a UART keyboard (unless you include Sun Type 5). M...

In my case the 1.5V result at the column means the four diodes were dropping about 0.45V each. You would normally expect a 1N914 or 1N4148 to be closer to 0.65V, but that is at a current of 1mA or more. This circuit conducts at most 66uA, limited by the 50K internal pull-down resistor in the input G...

jojopi

The described situation works for me. In fact, I can put up to four 1N4148 diodes and a 10K resistor all in series between the row pin driving high and the column pin pulling low. Then the voltage at the column is down to 1.5V, but still just enough to read as high. Five diodes is too many. Somethin...

I can't log in from the login-screen but is fine when i login from ssh with the same username and password, what could be the problem? Do you actually see a message such as "incorrect password"? If the screen just goes blank and then returns to the login dialog, your GUI session failed to launch. C...

VIH is the minimum voltage that will be seen on an output pin when it is High and the current draw is at the maximum level. Normally the output will be at or near 3.3V when High. The worst-case output voltages should be called VOL and VOH, while the names VIL and VIH are used for the levels require...

Also you really DO NOT want journalling on an SDCard. I know that you probably consider it a virtue, but you have wasted another two posts in this thread. The intent of the commands in the original post was to disable journalling. You are advising the poster to do exactly the thing he wanted to do,...

My advice to any C programmer would be always to compile with "gcc -Wall". Many of the people posting C questions on the forum would have had at least some hint to what their problem was if they had been using the diagnostics. Unfortunately, telling people to enable warnings is incompatible with tea...

limits.conf has been updated for both hard and soft limits, so no issue with ulimit. Have you actually verified that "ulimit -c" in a shell says "unlimited", instead of the default "0"? Does "sysctl kernel.core_pattern" also say "= core"? Any possibility your processes are faulting in a directory w...

That won't tell you what frequency it's running at, " scaling_cur_freq " contains the upper limit value for turbo. It won't change once the Pi has booted and will always contain the default of 1200, or whatever overclock/underclock value you've set in config.txt. As the name suggests, scaling_ cur ...

The fact that it takes so long implies that its doing division/remainder in a loop and not the sieve method. Each thread is effectively: #include <stdio.h> #include <math.h> typedef unsigned long long integer; #define max_prime 20000 int main() { integer c, l, t, n=0; int rep; for (rep=0; rep < 250...

Do american key boards really have an @ where the " should be? what a pain. No. Actually modern GB layout has @ where " should be. When bit-paired designs died out, British companies including Acorn , Apricot , and Sinclair adopted layouts very similar to the US. Somehow IBM won and forced you to a...

i've downloaded Elinks. same problem tho For me it seems that links transliterates ä as "a:", whereas elinks (if the system is misconfigured for non-ascii) uses "ae". Not quite the same, but in both cases clearly intentional. What are you seeing? Do you still have locale warnings on commands such a...

jojopi

You have had two problems: links seems not to want to display accented letters literally, even on a correctly configured system, as Heater already confirmed. I do not know if that can be fixed or not. Just use elinks as RaTTuS suggested on day one. LC_CTYPE="UTF-8" is an invalid setting (you cannot ...

"2>&1 1>> FILE" is not terribly useful. Redirections are processed from left to right, so this first attaches stderr to the initial stdout (which are normally the same anyway), then directs stdout only to the file. To redirect stdout and stderr together you need the order "1>> FILE 2>&1". Or to redi...
