  • The very first line:

    A loss leader (also leader) is a pricing strategy where a product is sold at a price below its market cost to stimulate other sales of more profitable goods or services.

    So the answer to their question is “Yes, a loss leader needs to lead to something”. I have no idea why you think they have no idea what they’re talking about.


  • It really depends on what you mean by “the real world”.

    The most common use for Linux is on servers. For this scenario, not only does the terminal make sense, but it’s often required as there is no GUI installed.

    For Linux on the desktop, the terminal is very much analogous to Windows PowerShell. More casual users can ignore it for most purposes, but may sometimes need it for troubleshooting.

    If you are trying to say that you “know” Linux, say for career development, you absolutely need to know the terminal. Nearly all professional roles will require it.









  • Are you able to physically replace the HDD (preferably with an SSD)? If so, you can use the (Win10) Media Creation Tool to create a USB installer.

    When it prompts for a key, just skip it. If you have an OEM mass activation laptop (i.e. anything from a major brand), it’ll activate automatically after. If, for whatever reason it still doesn’t activate, you’ll have a nag screen telling you to activate. It won’t significantly limit what you do.


  • It’s nearly certain. OEM activation has been stored on the motherboard since XP. XP-7 required a matching OEM cert (easily found online), while 8+ have a unique license in the BIOS. For these, you just reinstall the OS, skip the key during setup, and let it connect afterwards for all of the updates and whatnot.

    Now, licenses to other apps, such as Word, are not so simple.


  • Kind of. They will be multiples of 4. Let’s say you got a gigantic 8i8e card, albeit unlikely. That would (probably) have 2 internal and 2 external SAS connectors. Your standard breakout cables will split each one into 4 SATA cables (up to 16 SATA ports if you used all 4 SAS ports and breakout cables), each running at full (SAS) speed.

    But what if you were running an enterprise file server with a hundred drives, as many of these once were? You can’t cram dozens of these cards into a server, there aren’t enough PCIe slots/lanes. Well, there are SAS expansion cards, which basically act as a splitter. They will share those 4 lanes, potentially creating a bottleneck. But this is where SAS and SATA speeds differ- these are SAS lanes, which are (probably) double what SATA can do. So with expanders, you could attach 8 SATA drives to every 4 SAS lanes and still run at full speed. And if you need capacity more than speed, expanders allow you to split those 4 lanes to 24 drives. These are typically built into the drive backplane/DAS.

    As for the fan, just about anything will do. The chip/heatsink gets hot, but is limited to the ~75 watts provided by the PCIe bus. I just have an old 80 or 90mm fan pointing at it.



  • I don’t want to speak to your specific use case, as it’s outside of my wheelhouse. My main point was that SATA cards are a problem.

    As for LSi SAS cards, there’s a lot of details that probably don’t (but could) matter to you. PCIe generation, connectors, lanes, etc. There are threads on various other homelab forums, truenas, unraid, etc. Some models (like the 9212-4i4e, meaning it has 4 internal and 4 external lanes) have native SATA ports that are convenient, but most will have a SAS connector or two. You’d need a matching (forward) breakout cable to connect to SATA. Note that there are several common connectors, with internal and external versions of each.

    You can use the external connectors (e.g. SFF-8088) as long as you have a matching (e.g. SFF-8088 SAS-SATA) breakout cable, and are willing to route the cable accordingly. Internal connectors are simpler, but might be in lower supply.

    If you just need a simple controller card to handle a few drives without major speed concerns, and it will not be the boot drive, here are the things you need to watch for:

    • MUST be LSi, but it can be rebranded LSi. This includes certain cards from Dell and IBM, but not all.
    • Must support Initiator Target (IT) mode. The alternative is Initiator RAID (IR) mode. This is nearly all, since most can be flashed to IT mode regardless
    • Watch for counterfeits! There are a bunch of these out there. My best advice is to find IT recyclers on eBay. These cards are a dime a dozen in old, decommissioned servers. They’re eager to sell them to whomever wants them.

    Also, make sure you can point a fan at it. They’re designed for rackmount server chassis, so desktop-style cases don’t usually have the airflow needed.



  • I did this back in the days of Smoothwall, ~20 years ago. I used an old, dedicated PC, with 2 PCI NICs.

    It was complicated, and took a long time to setup properly. It was loud and used a lot of power, and didn’t give me much beyond the standard $50 routers of the day (and is easily eclipsed by the standard $80 routers of today). But it ran reliably for a number of years without any interaction.

    I also didn’t learn anything useful that I could ever apply to something else, so ended up just being a waste of time. 2/10, spend your time on something more useful.
