    This.
    They are the same thing, FCLGA is just the full name.
     
    Found this on the first page of google - https://linustechtips.com/main/topic/712464-will-a-fclga1150-cpu-work-in-a-lga1150-motherboard/

    The format is chosen based on the client's browser and system settings. If you want to change it, you need to build your own.

    Try a different cable. If that does not help, check if the device on the other side of your cable (router, switch, something else) has gigabit or 100Mbps ports.

    Share your network layout: wifi or ethernet, what cables, what network devices you have (routers, switches, firewalls, access points), what type of connection (fiber, DOCSIS, VDSL/2, ADSL etc) you have and so forth. When did the problem start, what did you change recently?

    jj9987 got a reaction from LienusLateTips in About Alder Lake CPU's   
    To be clear, the scheduler in Windows 11 can determine which loads should be on efficiency cores and which on performance cores. If OP is using Windows 10, it can be a hit or miss, because Windows 10 doesn't understand that cores can be different.
     
    On Linux, it sort of depends on the kernel version.

    You will need 48V PSU, yes. The 4 wires are red for +48V, black for ground, yellow for RPM reading and blue for PWM [1].
    Also, these server fans are meant to run in a data center, where noise levels don't matter. It will be very loud.

    jj9987 got a reaction from Zmimgo in "Normal" vs T-series Intel CPUs   
    I have some experience to share. I had a 3900x + X570-Prime-Pro in my server, that consumed approximately 100W in idle. Switched to a i3-10100 + B560M motherboard, dropped to about 50-60W.
     
    General consensus around homelab subreddits/communities seems to be, that Intel has better idle power consumption, whereas AMD has better load power consumption (and better price-to-performance etc).
     
    I do have a 4750G in a desktop, but I do not have a power meter at hand, to measure how much that system consumes at idle.

    jj9987 got a reaction from SorryBella in VPN question   
    Basically this. You are switching your trust from ISP to the VPN company. Depends on who do you trust more.
    Secondly, while HTTPS is secure and third-parties can not see your traffic, they can still see which IPs you are connecting to, which may or may not reveal information.
    Thirdly, TLS Client Hello in HTTPS is not encrypted, so it is quite easy to see the domain you are connecting to.
    Tracking is still possible, if you are still using same browser as usual.
     
    VPNs are critical in enterprise world. You can remotely access the internal network, be that web, file or some other servers.

    jj9987 reacted to tikker in VPN question   
    Safer browsing on public or unprotected networks (encrypting traffic), circumventing geo-blocking measures, putting an extra curtain between your ISP and your internet activity and maybe make tracking you ever so slightly more work (alhtough Google and like's tracking is quite advanced).
     
    Like you say it's not something that makes you completely anonymous nor something to hide from the authorities with. It's an extra layer of privacy. This is why people sometimes throw the "if you have nothing to hide..." argument at it. No, browsing LTT forums is not illegal (I guess), but that doesn't mean my ISP or anyone else needs to know I'm visiting it.

    "shouldn't" is a good term. They're not promoting Windows, they just make sure everything works on Windows and don't spend any extra time to see if it is possible on other operating systems. I remember from my 1st year in CS BSc, where we had to use some Sybase application for the databases course, which was only available for Windows at the time. Anything else wasn't permitted, because all their automated tests were built on that and if you used MySQL/MariaDB or PostgreSQL, it wouldn't work as SQL was slightly different.
     
    I agree with you, they shouldn't. Most courses could be done on any platform without too much hassle, but there were a few problematic ones. Also, since the instructors/lecturers aren't familiar with all the operating systems, don't expect very much support if you happen to get problems with one they aren't familiar with - this happened to a few co-students.

    Mac is a good choice, but speaking from my own experience...
    Depending on the university and the courses, you may struggle with running certain applications or achieve certain goals. Most courses had the materials and guides for Windows-only. Or the application that was required to use, was only available for Windows. If you used any other platform, you were on your own - run a virtual machine or what not. If you have courses with hardware, that require certain drivers, that's a whole new struggle.
     
    So my main recommendation would be that try to get familiar with the university's courses and what's used in them. If you are familiar with MacOS and/or willing to learn the command line and all it's tweaks and are willing to spend extra time to get stuff running, go Mac - great battery life, great performance, great build quality, great keyboard (assuming you avoid the disaster from 2016-2020) and great display. If you are rather new to computers, programming, hardware, drivers etc, Windows might be somewhat safer solution. In that case, a Thinkpad would be my first recommendation, followed by Dell XPS.

    jj9987 got a reaction from shadow_ray in This is NOT going Well… Linux Gaming Challenge Pt.2   
    I don't agree.
     
    First, the obvious - Linux is just a kernel, not an OS. There are tons of distributions, so everyone could find a suitable one, whether you are first time computer user or someone, who has worked on the Linux kernel for years.
    Second, why should it be limited to technical people only? If you only stick to technical people, who can find technical solutions, the simple problems will go unseen. A very good example was in 1st part, where Linus managed to wipe his XServer via command line - yea, there were problems with all involved parties, but it shouldn't be this difficult to install a simple program.
    Third, Arch is not suitable for someone who is just starting out to learn about Linux. There's a whole lot of stuff you can break already during the installation. After that, why would a simple computer user want to deal with installing their own audio drivers, when Ubuntu/Mint/Fedora and others have it packaged already? Every distro has it's place - you're a Linux guru or you want a real challenge then sure, go try out Arch or LFS. But if you are not that advanced user, who wants to try a Windows alternative, then it shouldn't be that hard to enter the Linux world.
     
    I'm gonna leave out some technical details/comments, these are more nitpicks than about the bigger picture here.

    jj9987 got a reaction from unijab in Will someone help how to do these tasks in linux?   
    No offense, but this question seems like a homework someone is too lazy to do. You got the knowledge already - cat, bash redirection operators, diff, head, tail, sort etc. Just try them out in a virtual machine or something.
     
    In addition, some of the tasks don't make a lot of sense, such as "File 4 save / dev / sda" - this makes no sense.

    jj9987 got a reaction from Vishera in What cluster should i use?,Can i host VMs on HPC clusters?,What can i do with HPC clusters?   
    A cluster is just a bunch of servers joined into a single cluster, for one or more of the following purposes:
    - High availability - when one physical node dies or is down for maintenance, move workloads to another one
    - Redundancy - replicate data on multiple physical nodes
    - Centralized management vs managing every physical node separately
    - Scalability - need more resources? Just add another physical node to the cluster
    - If your workload and clustering tool allow, you can spread your application over multiple physical nodes.
     
    The word cluster can be used in many ways. A HPC cluster is different thing - it is generally used for high-performance computing, where you need everything to be high-performance - your CPU, your RAM, storage, I/O, networking (not just 1 Gbps but 20, 100 or 400 Gbps), GPUs/TPUs etc. Workloads that belong here are related to AI/ML, science/research experiments, financial calculations etc. It is a rather specific group of workloads.
     
    If you want to just run VMs, you can setup a hypervisor and you're good to go. Got multiple physical machines? Set them up in high-availability, for example with Proxmox or ESXi.
     
    Next it depends on what workloads you want to run. A good starting point would be https://github.com/awesome-selfhosted/awesome-selfhosted or /r/homelab (it's wiki and other helpful posts like https://www.reddit.com/r/homelab/comments/5gz4yp/stumbled_into_rhomelab_start_here/
     
    There's a lot of stuff you can do and learn. All comes down to what you want to do, what do you want to learn/try out.

    jj9987 got a reaction from RockSolid1106 in My ip changed to a different country From hungary > to Netherlands   
    Do you even need the country to be correct?
    IP and country matching is usually done using GeoIP databases. These databases might have outdated information or the IP belongs to a company thats based in country X, but also has servers in country Y, but you could be seeing one or the other, depending on the service.
     
    tl;dr - country information isn't always 100% correct, don't depend on that.
