For any language with bitwise operations (like bash), just use &1; however, posix shell lacks bitwise ops, so you need to use the modulus operator % iseven() [[ $(($1%2)) = 0 ]] isodd() [[ $(($1%2)) = 1 ]] Hi technosaurus. Playing with your formula, like a kid with dough! n=33;[ $[$n%2] = 0 ] &...

Here are github projects to replace larger versions:

Yeah, the codebase is admittedly bloated. I usually just Google the function and go to whatever free-electrons page comes up ... they show where each symbol is defined and where it is used.

The kernel code is actually pretty easy to read, check out kernel_init in https://git.kernel.org/pub/scm/linux/ke ... .c?h=v4.15

There are plenty of examples in the gtkdialog tips thread as well as the gtkdialog source, but the best way is to look at the script of a program that does something similar to what you want.

I have often thought it would be beneficial to have a "simplification movement" where any bill, law or code longer than 100 pages is rewritten to 10% of its original size in plain language. As for the tax code itself, I'm all for a flat "disposable income tax" where only the inco...

smaller alternative to tinyX http://galos.no-ip.org/siX Good morning ,do you have the file ? I think galos is offline. Sorry for the late reply. The copy of siX that I had, does not include a license, so I can' repost it, but I did find some info here: http://betteros.org/tut/graphics1.php Its actu...

It looks like it may be able to do netflix - I may have a go at it.

I tried to get the samba server to be recognized by a second computer and it still fails to connect. Has anybody succeeded ? __________________________________________________ It is about time that I actually used samba myself! I am going to install Open Media Vault, have downloaded the iso. This i...

At the moment, its possible to reflash the firmware on systems that have it "enabled" for the user (mostly business class machines) but the images have to be signed. From what little I have found out though, it uses a builtin ARC processor (yes ARC, not ARM - not a typo) so it would be a l...

Yes, I found that source yesterday, waitforX.c: https://sourceforge.net/projects/tinycoremeta4s/files/source/tinycorelinux/3.x/release/src/ Here is a shell function to replace waitforX waitforX(){ while ([ ! -S /tmp/.X11-unix/X0 ]) do sleep .1;done } On second though, if you run multiple Xservers t...

If you haven't heard about Intel ME, its basically a backdoor built into newer Intel chips with Minix built in to on chip programmable persistent memory (I'm not sure what type) Intel presumably used Minix due to Linux's GPL license and the relative size of Minix vs the various BSDs, but if we were ...

strange you mention the blank screen with blinking cursor....I am experiencing this with new builds of Xenialpup 32 bit built with woof-CE testing recently. nothing is responsive but when power button is pressed the test sound is played (similar to woof-woof) no noticeable errors and does it also w...

2. This is an odd one. In Quirky 0.5/06, using jwm 2.3.7, one of the icons does not display in the menu. Everything is setup correctly. the pavrecord.desktop file has "Icon=mini-record.xpm" and the .jwmrc has the path to the icon, but it does not display. (see Multimedia menu in Quirky). ...

Yeah, that blinking cursor on blank screen is odd, I have sometimes got that too. JWM must be running. I have asked Joe, the author of jwm, for any thoughts on that. I am using jwm 2.3.7, which has at least two bugs, that I have informed Joe about. I wonder if get that blank screen if I roll jwm ba...
