  1. I have a TCL 4K TV from Amazon, trying to watch Star Trek: DS9 on netflix, and the resolution looks horrible, it's really blurry and I can't make out facial expressions even sometimes. Star Trek: TNG, which came before almost a decade before DS9, looks pretty good despite the 4:3 aspect ratio, although it can look super processed at times (imagine beauty mode on your phone was turned on all the time), it was still really good for a show made 25 years ago. Is there a setting or something I can change to make DS9 look at least as good especially since it came out later?

    SSD vs hardrive?

    There are so many cheaper drives on amazon: https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=1+tb+nvme+ssd I'd probably settle for a 2.5in SATA3 SSD which is half the price, but if you're loaded, go for it.

    SSD vs hardrive?

    The rig the SSDs are in are also in a older Sandy bridge system. I got a PCIe 16x to 4x4x4x4x NVMe adapter (not all mobos support these) drives in that. I got WD disks because plex gold gave me 20% off, so $160 for 500GB. If you really want to go fast (although there's no reason to), get the Intel Optane P900D, which is $500 for 500GB. But I wouldn't upgrade from what you already got unless you're running out of space. Unless you're virtualizing alot of machines with alot of IOPS or doing things live that needs to saturate a 10Gb connection, there's very little benefit to go for a modern NVMe SSD.

    SSD vs hardrive?

    Here's mine, it's not great but it's alright. A single lane of PCIe v3 is 1 gigabyte/s. A NVMe SSD takes 4 lanes, so even on sequential read, we still got lots of room to go up. Oh, keep in mind that this is in a VM, so it's not raw disk performance since there's virtio drivers and the (non-bare metal, linux KVM based) hypervisor layer.

    'Rent a pc' with Shadow?

    Looks like a Nvidia Geforce Now clone. Might be worth it if you can run normal server software on it. I wonder how much they overprovision...

    What Kind of Server to Build

    Generally the progression of intel CPUs over the past couple years went like this (for the dual CPU setup which is the sweet spot for homelabs): (X|E)55XX (4 core, Nehalem) -> (X|E)56XX (4/6 core, Westmere) -> E5-26XX (8 core, Sandy Bridge) -> E5-26XXv2(8/10 core, Ivy Bridge) ->E5-26XXv3 (12+ core, Haswell, DDR4 requirement)->after this point it'll be too expensive for hobbyists. Note the core number is not the thread number, server CPUs will usually have hyperthreading although I leave that disabled most of the time. Also, since these are dual socket CPUs, multiply that core number for 2 for the actual number of physical cores, and by 4 for the number of threads. The Nehalem and Westmere CPUs share a socket, the Sandy and Ivy Bridge CPUs share a socket. In the first 2 in the series, X is performance and E is the "normal" SKUs. The XXs generally represent 2 numbers, and the higher the numbers are usually the higher clocked/more cores the chip is. In Sandy Bridge and later, they got rid of the X and E labels and just used the 2 numbers at the end. Your i5-750 is a Nehalem quad core CPU clocked at 2.66GHz (Lynnfield to be specific). meaning it is on par with a X5560ish level performance. However, the X5560 is better for server use because it is a dual socket CPU (meaning it can do 8 cores, 16 threads while the core i5 can only do 4 cores, 4 threads), supports ECC RAM, and has hyperthreading enabled, on top of more PCIe lanes and 144GB max memory (compared to the 16GB for the desktop chip). The R710s are a popular series of Dell prebuilt servers that usually dwells around the (X|E)55XX and 56XX eras. I had a Dell R710 with 2 X5550 CPUs. If you build a white box, Sandy Bridge is the most economical. But even the worst Dell prebuilt R710s ($100 on eBay) will be around 3X better performance (2 of those CPUs with hyperthreading and unforgivingly loud cooling) than the i5-750 with 4GB RAM. A E5-26whatever will be miles better because it has 2x the number of cores as well as newer instructions like AVX and maybe some newer video codecs built in. But you got to ask yourself if you actually need all this power. Because at the end of the day, even the R710s were designed to host multiple VMs and it doesn't sound like you actually need multiple VMs if a shared hosting service was enough for you before. I'd seriously suggest looking into AWS or something like a cheap Kimsufi box ($15ish a month for a dedicated box with server infrastructure) before committing to putting a server in your bedroom. I was able to simultaneously host 3 modded minecraft servers, and 4 srcds instances with 10s-low 100s of concurrent connections with 2 X5550s and 64GB RAM in an R710 without it breaking a sweat. Only when running school stuff that's designed to max out your CPU usage for days is there actually a benefit to switching to the Sandy Bridge architecture (that and the silence/low power consumption). At that point, it'll be your internet connection that's the limiting factor. I never bothered shipping anything to Canada (I used to live there), I'm in the states now and shipping is easier, it'll generally be up to the eBay seller if they want to ship internationally and/or want to charge you an extra fee for it and/or not take responsibility when customs rejects the item/puts heavy brokerage on it.

    What Kind of Server to Build

    Yeah, if you aren't building a server in the interests of building a server, I'd go with AWS. There's only a few scenarios where a dedibox in your room is going to be better (I get free gigabit up and down with a static IP from my dorm 2 hops away from the west coast exchange, so that's one of those scenarios, if you have a dynamic IP that changes often and not much upload bandwidth from an ISP that may block ports than obviously that's not worth it, and even then I'd have to get a 4U for noise reduction before thinking about sleeping with it even in the closet). Believe it or not the old hardware actually went up in price since that article was published (in CPU and motherboard, the old mobo went up to $400 new from $300s, it's crazy) It's more expensive to get now so I'm glad I got it when I got it. But you can still prawl around eBay and find a pair of E5-2650s for about $100 (https://www.ebay.com/itm/Matched-Pair-of-Intel-Xeon-E5-2650-CPUs-2-0GHz-8-Core-SR0KQ-Socket-2011/302772707266?epid=28011375144&hash=item467ea8dfc2:g:SBEAAOSwuHFbEF68:sc:USPSFirstClass!91125!US!-1). I got a R710 shipped from NY to CA for less than $100 (the shipping was more of that $100 than the actual machine). Although it only had 4GB of RAM, but RAM is cheap at $2/GB for DDR3. I did have to win an auction war though, typically to get the same setup I did for buy it now would be twice as much. Something like this listing (https://www.ebay.com/itm/Dell-Poweredge-R710-2-X-SIX-CORE-2-40GHZ-E5645-8GB-MEMORY-2-X-72GB-10K-SERVER/132661973709?hash=item1ee34512cd:g:tkUAAOSw-4BXZDg1) or this (https://www.ebay.com/itm/Dell-Poweredge-R510-2-X-QUAD-CORE-2-40GHZ-E5620-8GB-MEMORY-H700-12-BAY/132663257744?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D52570%26meid%3D65c9910a5cb741bc9bbeede4352f3fa8%26pid%3D100005%26rk%3D10%26rkt%3D12%26sd%3D132661973709%26itm%3D132663257744&_trksid=p2047675.c100005.m1851). Just search eBay for Dell R710 and sort by price, there's lots of e-recycling companies that get these from IT departments all over for free and are turning a small profit with them. Beware of loud fans though. And make sure it can take 3.5in harddrives or else you're gonna have to spend alot on 2.5in SAS drives (or SSDs), oh and also, get an HBA card if you get an old server the old dell SAS backplanes only do RAID.

    Server with up to 1tb ram and can support 8 in the future!

    Yeah $33k that will depreciate faster than a new Mercedes. Just wait a few years and pick it up for $1000 on eBay.

    What Kind of Server to Build

    Probably overkill but here's a nice 16 core (32 thread) server build for cheap (I personally run 10 VMs off these with 4 threads per VM with 64GB RAM, it is wonderfully snappy). https://www.techspot.com/review/1155-affordable-dual-xeon-pc/ If you aren't running VMs, your current setup has probably the same compute power as a middle-of-the-road VM (VPS). I'd suggest looking into AWS spot pricing and seeing if its actually worth it building your own if you aren't out to 'build a server' rather than just use it. You don't need a graphics card for a server (unless you specifically want to use one for a specific purpose (TensorFlow, etc..)) If you do build a server though, don't go to skylake+ (with the exception of maybe some Xeon Ds). The RAM prices are atrocious. You can get old server RAM for like $2/GB for DDR3 but DDR4 is like $10/GB or something ridiculous like that. EDIT: Forgot to mention you can get some old R710s off eBay for $100. Dual CPU, 8 core 16 threads, redundant power supplies, and like 24 DIMM slots/8-10 HDD slots/4 NICs in the same generation as your old computer. But good luck sleeping or keeping your sanity near those fans.

    Disable Windows Updates for Good

    I tried doing a registry hack (https://support.microsoft.com/en-us/help/328010/how-to-configure-automatic-updates-by-using-group-policy-or-registry-s) and it did work for a couple months, maybe an update undid this?

    Disable Windows Updates for Good

    I'm in a molecular biology lab. We have a Windows 10 machine (was Win7, woke up one day and it's 10) as the driver for a spectrometer. We do overnight incubated kinetic measurements with the reader but recently, Windows updates keeps happening and keeps rebooting the computer in the middle of the night. Each of these experiments takes ~1 week to setup and it's really ridiculous that we're getting unreliable data because of Windows updates. What's the most painless way to stop this for good? It would probably be really expensive to reinstall Windows since we'd have to have a tech come in from the company to setup the software and connection again. We would cut internet access for good, but sometimes we RDP into the machine to see runs in progress, so we'd prefer not to.

    Should I go with MSI or Asrock?

    The asrock one has the following advantages: 1 PCIE x16 vs. 1 PCIE x1 2 more RAM slots Cheaper Not familiar with AMD chipsets though, if they have the same chipset, then Asrock.
