  • Those tests are worth more than four years of college?

    Yes a test to figure out if you can perform your job is significantly more valuable than a collage degree, this doesn’t mean that college has no value, mind you, it just means that knowing how to do the job and knowing that you fit in with the company culture is vastly more important.

    Go get a bunch of I.T. certifications. Get your CompTIA A+, Network+, Security+ Get a Microsoft MCP or MCSA

    Those certifications are useless, they look good on your resume because managers love showcasing their staff’s “certifications”, as many companies that don’t understand IT put value on the certifications more than anything else, but they don’t actually provide you any value in of themselves. Sure it might be interesting how many network switches you can daisy chain according to the standards, but it has no real value most of the time, if that’s information you need in your job it’s something you can just look up, HOWEVER, asking you random questions that pertain to the job during the interview IS a good way to understand if you’re a good candidate, and, often, the actual response doesn’t matter as much as your reasoning for getting to that response.

    When an interviewer at google asks you how many pennys it would take to make a structure as tall as the empire state building, it doesn’t matter what the answer is, truly, even if you got the exact number of pennys, just saying the number would mean you don’t pass the interview, your answer would be worth less than an answer that gets it wrong by 75% but is well reasoned, what they care about is how you come up to the conclusion that you come up with, the solution is useless.





  • I believe that the following IP ranges

    • 103.231.144.0/24
    • 192.31.196.0/24
    • 216.176.216.0/21
    • 199.248.239.0/24
    • 192.198.30.0/24
    • 69.12.98.42

    are engaged in highly suspicious activities

    furthermore I can definitely say that I found some dirty pirates hiding at the following ip ranges:

    • 175.45.176.0/24
    • 175.45.177.0/24
    • 175.45.178.0/24
    • 175.45.179.0/24

    my research clearly shows proof that those people are not just pirates but also engaged in highly illegal activities such as stealing BILLIONS of dollars and hacking who knows how many servers, and that’s only the crimes one can talk about online.


    if you don't get the joke

    no, I didn’t share IPs that anyone here would ever have, I guarantee it, if you don’t get the joke look up “bogon routes” and then look up which ASN owns the other set.

    It looks more legit than people who use 192.168.0.0/16, 8.8.8.8, 127.0.0.1, or any other things like that because most people don’t know about those.

    Also bonus info:

    here’s a tip for you, if you’re a sysadmin just go ahead and ban those IP ranges on your machines, if you ever get packets from them it’s an attack 99.999999% of the time (I guess unless you have customers in north korea? in which case only block the first ones and all other bogon routes)










  • In general I agree with you. I find that most FOSS software is more polished than proprietary software, and it is generally more powerful.

    However, I think that one problem that people somehow overlook in my opinion is that the financial side of the issue is also extremely important. I want more people to work on quality FOSS software, and I want it to become socially acceptable to work on FOSS as your main job. For that one thing is needed in my opinion: we as users of FOSS software need to give developers the financial incentives to work on what they love the whole time. In fact I want it to reach the point where immoral, non FOSS companies struggle to find developers because they’re all working on FOSS.

    I prefer the extremely intuitive:

    [C-R]=system("grep -P "PPid:\t(\d+)" /proc/$$/status | cut -f2 | xargs kill -9")

    or

    i:!grep -P "PPid:\t(\d+)" /proc/$$/status | cut -f2 | xargs kill -9[esc]Y:@"[cr]

    It just rolls off the fingers, doesn’t it?

    Edit: damn it lemmy didn’t like my meme because it assumes that characters between angle brackets are html tags :( you ruined it lemmy

    EDIT 2: rewrote it, just assume that square brackets are buttons not characters



  • in this case the instruction set is extremely small (and includes open source verilog, so you could even fab it yourself)

    quote from the website:

    The CPU of the TKey is a modified version of PicoRV32, 32-bit RISC-V running at 18 MHz. Modifications includes a fast 32x32 multiplier implemented using the multiplier blocks in the iCE40 DSPs as well as a HW trap function.

    The supported instruction set supported by the CPU is a subset of RV32I. Specifically it includes compressed instructions, but excludes instructions for:

    • Counters
    • System
    • Synch
    • CSR access
    • Change level
    • Trap redirect
    • Interrupt
    • MMU

    The instruction set implemented by the CPU also includes multiplication instructions from the RV32IC_Zmmul (-march=rv32iczmmul) extension. Division is not supported.

    Any illegal, unsupported instruction will halt the CPU. The halted CPU is detected by the hardware, which will blink the RGB LED with red to indicate the error state. There is no way for the CPU to exit the trap state besides a power cycle of the device.

    Note that the CPU has no support for interrupts. No instructions, ports or logic.
