I got a thinkpad E14 off of eBay for $400. There was a slight haircrack in the hinge, but it came with 40gb of ram 1tb ssd and amd ryzen 7730u I believe. I always recommend looking on eBay first, it’s likely you can find a $1000+ laptop for $400 like I did.

I’m a student, I’ve strictly removed myself from this fucked up story. I’ll be it, in my CS class with about 125 student, I’ll say 87℅ of them use chatGPT, probably even more. It’s easy to see that almost everyone in the class cheats, I spend about 5 days on a project or lab, they spend only 1 day. Its not that they’re good at CS, this is after all an “introductory” CS class, and at the moment were learning data structures. Everyone hates data structures, and the people I talked to said “yea I spent a day on the linked list lab and got 100” it is so rare for me to get a 100 in this class, and I spent 5 days on that lab.
I’ve completely removed myself from using chatGPT and other LLM’s. for fuck sake, I’m using a query based search engine called marginalia search, because even the internet has been fucked with unreliable information.
I love it because now I don’t have everything at my fingertips, I do have a few things with the search engine, but you have to conserve the words that you use and not everything will pop up. For example, You can’t just search “how to concatinate numbers in c++” you need to say “string concatenation c++” since you’re using too many keywords
Because of this, I’ve started checking out library books from my university, and what’s so funny is that the books I checkout aren’t due for months in advance because no one checks out books anymore. I got a book on C/C++ reference guide and it isn’t due till January of next year.
Yea, I had a server with a nvidia GPU that was orginially on windows. I went with ubuntu, and the installed nvidia driver (when ubuntu asked to install any drivers) gave a horrendous aspect ratio that didn’t fill up the entire screen. I had to uninstall the driver to get it to work.
Came from windows laptop that I got about a year ago, before then I was running unironically chrome os. I liked chrome os for it’s Linux features. So when I did go from my Chromebook to a windows, it wasn’t as fun. I also didn’t like all the spyware on windows, and this was the time when I was removing myself from the internet as if I didn’t exist, So it was inevitable I would switch.
The only reason why I haven’t switched earlier is because I am a university student (currently in electrical engineering) and I was concerned that I would be given an exotic application that my laptop cannot support on Linux. Then I learned the majority of students have macbooks, so if it doesn’t work for me it doesn’t work for them too. That’s when I made the conscious decision to switch from windows to Linux.
Currently trying out fedora workstation, it is like the Mac os of Linux operating systems (and that’s a compliment).
I’ve been using fedora workstation for about a month now, you really can’t go wrong with it. It’s great for laptop, there are also ways to customize it to work with a desktop. I am running it on amd CPU/GPU, so i don’t know how well it works with nvidia and Intel, I know some distributions do a really poor job managing the drivers. I don’t use CAD, but I have done FPGA design and programming (C/C++) and it works great. Haven’t done much gaming, all I have is minecraft installed, I could imagine you can install steam on there as well. Hope this helps.

Programming Humor@lemmy.world•Or when you restart your computer......English
1·8 days agoI can’t tell you the number of time I restart my computer and my code starts working.
I spent 5 days last week doing a lab assignment on linked lists, spent 3 days trying to debug my code, turned off and on my computer and it worked. I suspect it’s a cache issue where there is some corrupted cache that isn’t being updated and that can only reset through a full restart.

Programming Humor@lemmy.world•POV: You just got your first webmaster job in the 90sEnglish
1·9 days agomy professor got pissed at us once flunking our exam in C types and he was telling us to ask questions if we don’t know “for example, how to convert from binary to hexadecimal” from that point onwards the class started asking questions out of fear of being critiqued. This meme is very relatable.
I didn’t fully understood the joke, my only understanding of episilon comes epsilon-delta proofs… I forgot that epsilon in that context measures the certainty of the “Infinitesimal” displacement in x. So when epsilon is really large everyone looses their shit as if the world’s going to collapse into a black hole. 😂

You seriously can’t go wrong with the lenovo thinkpads on eBay. I Got a thinkpad E14 ryzen 7 (7th gen), 48gb ram, 1tb ssd for $400 on ebay with a small hair crack on the hinge.
At the end of the day, a laptop is a laptop, and the cost difference between a $2000 brand new laptop and a $400 used laptop there really is no argument/justification to be made to buy a $2000 laptop in less-intensive tasks. Here’s a better instance of your money: find a $400 laptop with semi-good performance (ryzen 3 or intel equivalent) put $1600 to a gaming computer and setup a virtual environment with a radeon or rtx gpu at your fingertips.

Ask Science@lemmy.world•How does Uranium decay work? (A lot of questions)English
2·4 months agoIdea have been summoned.
Any type of decay, either that be uranium (U) strontium (Sr) thalium (Th), it is caused by an imbalance of radionuclide’s (protons and neutrons) in the nucleus. This is not to confuse with an imbalance of protons and electrons which changes the charge. Basically the nucleus wants to be balanced (IE: x amount of protons and neutrons). If there’s an imbalance of radionuclide’s in the nucleus, it will emit them as forms of radiation.
There are three kinds of radiation that can be emitted by a radioactive isotope; alpha, beta, and gamma.
alpha radiation is the heaviest of the three, containing two protons and two neutrons, it is also the weakest in penetrating power because of how much mass it has. You may have also noticed that alpha radiation takes the form of a helium nucleus from its proton-neutron count, that’s because alpha radiation is a helium nucleus!
Beta radiation is comprised of two forms beta plus (B+) and beta minus (B-). B+ is a positron and it’s a very uncommon form of radiation. I think carbon-13 is an emitter of B+. B-, on the contrary, is an electron and is far more common/abundant across many radioactive isotopes. Th-204, is, approximately, a B- only emitter. U-238 is also a B- emitter.
Gamma radiation doesn’t have any mass, and is light making it the most potent of the three.
Now to answer your questions:
“What happened to the respective electrons?” I think your confusing the difference of a helium nucleus and a helium atom, the helium nucleus indicates the number of neutrons and protons, it does not include the orbiting electrons of which the atom does includ. Alpha radiation is a helium nucleus not a helium atom
“Does this mean that each uranium atom, with 92 protons, entirely splits into 46 helium nucleei or does it release some number of helium nucleei leaving another element behind?” I highly recommend looking at the U-238 decay chain wikipedia article, it Illistrates how the decay chain process actually works. To answer your question, U-238 releases a helium nuclei during its decay chain process leaving strontium-xyz (forgot the isotope name).
“How does the concept of half life play into this?” Half-life states that for a given radioactive isotope how long does it take for that isotope to decay half of it’s initial quantity. I think for uranium-238 it’s 4.5 billion years or 9 billion years to fully deplete itself of any radiation.
Yea no, it’s not that bad. Jediism is also a pretty cool religion content-wise unless they somehow fucked up the story of star wars. Just like how the Jews, muslums, and catholics couldn’t ever talk about their parent religion Assyrianism; oh what a fucking disgrace that would be.
https://en.m.wikipedia.org/wiki/Jediism
it would be so much more interesting if these major religions did talk about there parent religion asyrianism and/or roman mythology. Its far more interesting than asking a rabbi “what shoe I should tie first” or “why do I have to cut my finger nails in a specific way as if I have dyslexia.” 😂
Anyways I’m getting side tracked here, basic premise is, an AI religion – which some may argue already exists (talking to you Sam altman) – as long as there’s truth to it, is far better than any other religion
Hey, we got our prioritizes. my form of therapy is cursing at the computer when my program doesn’t work. 😂
I’m guessing this “homeschooling” will start well, and then go on a complete fucking tangent where they now believe AI is god, and make a god damn religion through it.
If someone’s so passionate in AI, where he removes his kids from school to homeschool them, the end result is not going to be fucking pretty.
