Advice? in c/transprogrammer@lemmy.blahaj.zone
[–] nekomusumeninaritai@lemmy.blahaj.zone 1 points 1 year ago

I completely agree with you about motivation in isolation. I've been doing a bit more this past week, but I need to keep pushing myself to stay focused on the same project after a day or so. It was easier in college because I had more external motivation. I did have the idea recently that I could learn a bit of graphics and get a bit more motivation out of what I code. I'll probably stick with that for a couple of months because it is a fairly versatile skill to know how to tell the GPU to do things. Additionally, thank you for letting me know about the Out in Tech group. It sounds like it would be helpful.

I'd imagine you want something defined recursively like multiplication

  • ( 0x = 0 )
  • ( xy = x(y-1)+ x ) ( y > 0 ).

So it needs to be

  • ( x^0 = c ) (c is some constant)
  • ( x^y = xx^{y-1} ) (( y > 0 ) (to see why, replace multiplication with exponentiation and addition with multiplication). So what could ( c ) be? Well, the recursive exponentiation definition we want refers to ( x^0 ) in ( x^1 ). ( x^1 ) must be ( x ) by the thing we wish to capture in the formalism (multiplication repeated a single time). So the proposed formalism has ( x = x^1 = xx^0 = xc ). So ( cx = x ) hence ( c = 1 ), the multiplicative identity. Anything else would leave exponentiation to a zeroth power undefined, require a special case for a zeroth power and make the base definition that of ( x^1 ), or violate the intuition that exponentiation is repeated multiplication.

On an unrelated note, it'd be nice if Lemmy had Mathjax. I just wrote all this on mobile with that assumption, and I'm not rewriting now that I know better.

I would've appreciated a trigger warning on the post since it uses a slur, but wow, it is amusing (I'm sure it'll be less amusing once I experience more overt transphobia).

They just said :wq in school, so thanks for the tip. Hard to believe it saves even when the file hasn't been changed if you use :wq. What is the use case for that? If the file gets changed in another program and you want to revert?? Edit: Just saw the comment about the modification times being updated.

Advice? (lemmy.blahaj.zone)
 

Hi, I'm not sure if this is the right community to ask this, but I got yelled at by my mom today for not having a job and I thought it might be worthwhile asking what sort of strategy I should pursue from a community of people with skills I would like to develop. I graduated with a bachelor's degree in Computer Science from a mid-tier state university in the US before the pandemic, but didn't really do anything to develop my portfolio. I had good grades and got two interviews for software engineer positions, but didn't get the job in either case. I didn't really care too much. I was still an enby egg and everything felt off, so I never looked very hard. When the pandemic happened, it made finding a position out of the question because my parents are high risk. Unfortunately, I have had trouble developing a portfolio. I don't know if my education is lacking or I missed something or it is my ADHD or I am just not talented and got fooled into thinking I was okay by grade inflation, but I could never focus for long enough to figure out anyone's project and make a contribution. I did a bit of Cracking the Coding Interview, but got bored a chapter or two in and haven't gone back to it in a while. So I guess specifically my questions are:

  1. Am I correct in trusting the common advice to contribute to open source projects to build a portfolio?
  2. If so, how do you figure out how to gauge your skill level so that you pick the right projects to contribute to? 2a. How long does it take you to get up to speed on a new project before you feel comfortable contributing? How long did it take before your first job?
  3. Am I correct in thinking that any credit I get from employers from having a CS degree is strongly outweighed by 5 years of not having a job and no contributions?
  4. Should I consider looking into the resources I (and my mom) have heard about offering autistic people help getting into technical fields? I don't think my autism is that bad, and I'm not particularly talented either, so I'd dismissed these for the most part.
  5. How do I avoid positions that don't either build my skills or lead to a career?
  6. I am prescribed and taking medicine for ADHD. Is there anything I can do beyond that? My mom has talked about hiring a “life coach,” but it has always sounded like a good way to spend money for no benefit.
  7. How do I motivate myself when I'm probably mediocre and will be treated like shit if I “succeed?”
  8. Am I thinking about this all wrong somehow?
  9. What are the best resources for someone in my position? Despite how it may sound, I am willing to put a fair bit of effort into self-improvement, it has just been spread far too thin because of the ADHD.

5 Reminders NOT to Pre-Order Games This Year ~ We used to demand trials before buying before, what happened? ~ Stop Pre ordering Games in c/games@lemmy.world
[–] nekomusumeninaritai@lemmy.blahaj.zone 1 points 1 year ago

That's certainly true. I'd still say that for the online stores, for which that policy applies, there isn't a lot of upside to preordering. Because the purchase is digital, you will always be able to get a copy on release day (unless the publisher artificially limits how many games it will sell, but I've never heard of a publisher doing this).

Financially, preorders without a “preorder bonus” are a zero interest loan to the developer. Preorders with the “preorder bonus” are a loan with the bonus as interest. Even if the game were guaranteed to be good, you could most likely be doing something better with the money until it comes out. Since the game is not guaranteed to be good, it is a risky loan as well. Without any of the protections you get when you make an actual loan.

Some commands to confuse the newbies (post from GNU+Linux Humor) in c/programmerhumor@lemmy.ml
[–] nekomusumeninaritai@lemmy.blahaj.zone 7 points 1 year ago

It's also helpful to note that “shell builtins” don't typically have man pages (at least for BASH). You can find help on these commands by typing [builtin name] --help or looking in the shell's man page or info doc (no one told me when I was learning, so I got confused as to why some of the more common commands didn't have man pages)

Don't worry. It was a bit ambiguous 👍

This should work with some caveats.

  1. Tbis probably won't work on WSL (Linux needs direct access to your hardware).
  2. For DVDs, you need to be sure libdvdcss is installed for this to work correctly
  • You probably already have this on your system if you have successfully watched a dvd in Linux.
  1. You may need to replace /dev/cdrom with the name of the device file corresponding to your drive.
  1. This creates an exact copy of the disk, including the unallocated space. You would probably want to follow the guide https://wiki.archlinux.org/title/Optical_disc_drive#Creating_an_ISO_image_from_a_CD,_DVD,_or_BD
  • (@BustedPancake@lemmy.world's use of mkisofs does the same thing because they copy the files on the disk rather than the whole disk. But you don't need makemkv. You should be able to use any method of copying the files and Linux should use libdvdcss to decrypt them.).

“deep magic”Linux trys to treat devices like files. If you ran xxd /dev/cdrom, you would see every bit on the disk (not just those of the files, but those in the free space as well) in order from the first to the last (converted to base-16 in what is called a hexdump). Not that you need to see this, but your video player does. The “DRM cracking” is actually a feature of libdvdcss that makes it possible for the system to treat the disk this way. dd is just a general copying command and if Stack Exchange is to be believed, it isn't necessarily the best option (https://unix.stackexchange.com/questions/12532/dd-vs-cat-is-dd-still-relevant-these-days). But it probably is necessary for the linked guide to work because it has dd truncate the file.

edit: caveats is note spalled caceats

edit: file → files on the disk

I guess you could say this meme is… a copycat.

Yes, normally you'd redirect it to do something useful. But I'm not editing it.

edit:remove duplicate photo

edit2: Silly me for thinking that Lemmy was smart enough to grab the first body photo as its thumbnail. Also set language.
