So I just got my fresh Openbsd7.5 installed.As you can see, I'm very new at using this OS. It's still in barebone condition with fvwm running as default gui. The best part about this OpenBSD installer is that It came together with mandatory full disk encryption setup. Though, I'm still not used to some of the commands. Like for instance, how do you look up for all the openbsd packages that already been installed?
Anyway, according to guide I followed here
https://www.tumfatig.net/2024/openbsd-workstation-for-the-people/, I need a proper DE for my computer. All the DE that are available in Openbsd doesn't seem to suit the taste of my liking. I like my DE to be extreamly low resource usage. That DE where I'm looking forward to use is known as the Equinox Desktop Environment (EDE).
Let me tell you some my experiance using EDE on archlinux. Unforunately I didn't manage to get it running properly. It was borked from the get go where all the application I have from the start menu were not functioning. I was quite dissapointed by it, although I do read somewhere that there were success story of anon running it on Devuan. Maybe that is why I shouldn't give up just yet because I really want this DE up running flawlessly.
So given the option here, It looks like theres 2 methods on how to get this EDE installed on Openbsd.
The 1st one is to compile from source according to instruction here
https://edeproject.org/wiki/installingfromsourceThe 2nd one is by using their install script called netinstall. Everything about netinstall is decribe here
https://edeproject.org/wiki/netinstallThe 2nd option looks a lot easier, but I dont know whether this actually works. Well, I think it doesn't matter whichever of the options here, wish me luck anon.

My tower has finally broken. After half a decade of steady sevice and four operating systems it's finally kill. Ethernet port (built directly into the motheboard) broke mysteriously and I can't get any internet period (currently phonefagging at work). Though it was having serious overheating and regular freezing for a long time, I really should have replaced it long ago. Thinking of getting a laptop/dock combo to replace it, any recommendations? I don't need much power, but enough to do light compiling and video encoding without completely locking up. I also want hardware that will run linux hassle free (I never want to deal with nividia drivers again) and isnt completely locked down, that last ones the real kicker; it's so hard to find modern laptops that you can even replace the battery on. I remember hearing about a company making modular laptops that as I recal sound perfect for me, but I can't remember their name; currently trying to find that.

>>2304>it's so hard to find modern laptopsThat's the real problem. If you don't want all the shitty drm locking up your hardware, you have sacrifice from using modern hardware. I still using AMD Desktop pre 2013 era and I maintain in a good condition. Even my laptops runs on old amd processors from 2009. Of course you need a good CPU fan and thermal paste for your pc to be resistant from overheating. A big desktop casing also helps the air flow ventilation and keep the tempature of your pc under control.
>it was having regular freezing for a long timeYou also need to check whether your PSU or your power supply are powering enough voltage. In your bios, you could see the voltage status for 12V 3.3V and 5V. If for instance, your 12V doesnt reach enough threshold (e.g 11.734v). You're going to have freezing problem. To mitigate this, you can try tune the voltage usage up by 0.01v for vcore and nothbridge until you reach the stability of 12V threshold.

Quadposter here to say thanks for the suggestions and that I've found the brand of modular laptops I was rembering: Framework. They do seem really nice on paper but I wonder if their build quality is up to having whole sections like the keyboard being removable. Also doesn't seem them or system76 make the drop in docks I was hoping for. And in looking into laptops I'v realized I really like bulky my 100% keyboards and laptops just don't have them. Maybe I should just get a new desktop instead. Or follow the hype and look for an old thinkpad on ebay.
I'm over reluctant to buy things at the best of times, combined with decision paralysis and the fact that I have do do all my research and eventual buying on my phone is making me put this off far too much. I should just buy something dirt cheap and get something else if it doesn't work.

>>2522This is a surprisingly hard problem... I think it can be done with PCRE, which is supported by grep, but it's not nice.
First, match for all words:
> $ echo what wat lat latte blat | grep -P '\b\w+\b'> what wat lat latte blatI bolded the whole but the spaces are actually not highlighted!!\w means "word" character, so not whitespace, and \b means the beginning or end of a word. Next, try a negative lookahead. It looks like "(?!PATTERN)" and means that whatever comes next, cannot match PATTERN.
> $ echo what wat lat latte blat | grep -P '\b(?!lat)\w+\b'> what wat lat latte blatThis did not catch "latte", because it starts with "lat"... Maybe a negative lookbehind would work? It look like "(?<!PATTERN)" and means that anything you matched before, cannot match PATTERN.
> $ echo what wat lat latte blat | grep -P '\b\w+(?<!lat)\b'> what wat lat latte blatThis did not catch "blat", because it ends with "lat"...
My solution would be to say, if it is three letters long and those three letters are "lat", don't match. The only way I know to express is to have three cases: less than three letters, exactly three letters, more than three letters. I ended up with this:
> $ echo what wat lat latte blat la | grep -P '\b(\w{1,2}|(?!lat)\w{3}|\w{4,})\b'> what wat lat latte blat laWhich is ugly as hell but matches words expect for "lat". Which might not be what you actually wanted...
The problem is that if it's not matching words, "lat" will inevitably get included in two parts, like first matching "what wat l" and then "at latte blat la", or something. Maybe there's an easier way...
Why do you want to do this?

>>2523I finally figure it out. Sorry for bringing you into this hurdle. Im just trying to find what is the ideal solution on using grep -v in this situation. Isn't grep -P derive from Pearl regex? lol, there's no way I'm gonna use all these wierd syntax.
Anyway here's my take on this. I think the best method to discard any word that has lat from sentance or paragraph is by using sed. Convert all the spaces into a newline with sed and then, invoke the grep -v lat. Now every lat word has been discarded but I need to convert the non disacarded lines back into sentance. So the best way to do this is by piping it wih xargs, and there you have it.

No.2733
>>2730It wouldn't be smart, because it wouldn't work correctly with multiline input. If you persist, you may do this
echo what wat lat latte blat la |
awk -v RS='[[:space:]]' '!/.*lat.*/ { str = str " " $0;} END { $0 = str; $1 = $1; print }'

No.2907
>>2906When an integer reaches the limit of its type, it's called an integer overflow/underflow. On some CPUs this will cause a fault, but usually it just wraps around. Wrapping around means that with an unsigned 8-bit integer type, 255 + 1 = 0, 255 + 2 = 1, 255 + 3 = 2, and so on (also 254 + 2 = 0, 254 + 3 = 1, you get it). With signed integers, wrapping works the same way, but it starts with the negative value. For a signed 8-bit integer, 127 + 1 = -128, 127 + 2 = -127. And the other way, too: -128 - 1 = 127. You can look at how CPUs implement addition/subtraction to see why, it's just this is the easiest and fastest way to do it.
A buffer overflow just means that you wrote more to a buffer that it can hold, and you overwrote whatever was next to the buffer. If you have an array of 128 uint8_t, for example, but wrote 200 bytes to it, it will overwrite whatever happens to be next to it in the memory. If you are lucky, your program will just crash, but otherwise anything might happen. If you are lucky, a talented attacker could craft the input in such a way that it overwrites the next stuff with just the right thing to cause all sorts of nefarious things, in the worst case maybe even executing the attacker's own code. You need to check if your input will fit its destination and careless handling of integers is often a source of too lenient checks. But you can have a buffer overflow due to other issues, too, it's not necessarily linked to integer woes.

These are usually only a concern with low-level languages like C and C++. I don't know how much of an issue is it for Crystal because I never used it, but looking at the Learn X in Y minutes page for it I could check this at least:
> num1 = 255_u8> puts num1.class> num1 += 1_u8> puts num1.classAnd it looks like in Crystal integer overflows are actually faulting, and not wrapping!
But you can ask it to wrap:
> num1 = 255_u8> puts num1.class> num1 &+= 1_u8> puts num1.class> puts num1And this behaves as described above. Fancy!
I hope this actually helps and does not confuse you even more…
