  • It’s been a long time since I used Windows myself, however one of the big reasons for switching was the inherent instability. At once point I was developing code in Visual Studio and constantly loading/closing quite a few different programs to test things out. Windows just didn’t seem to handle memory-recovery and I would have to reboot every week or two (usually because of the whole OS locking up). In comparison, I run a variety of software on my linux machines which can involve anything from testing code in multiple browsers to image editing to 3D CAD drawings. Sure that tends to drain the memory but when I close something I get that memory back. I’ll frequently get down to the last 100K of RAM, close a couple programs that may be holding large caches (Firefox really hates me having hundreds of open tabs), and then I’m right back up and running again. Reboots may occur about every 6 months.

    I have to support other people using Windows at work, which reminds me how much I’ll never go back to it. My biggest frustration is that Microsoft is constantly changing things. Hell you can’t even directly reach the control panel any more, you have to run searches to find the specific item you want. Want to check the settings of a certain printer? Good luck, that doesn’t seem to be available in the right-click menu any more. It’s just all these idiotic changes making it difficult to actually use or maintain Windows. Why should I have to google how to find something when everything used to be under the control panel or a right-click away?





  • Want to see shit really hit the fan? Imagine if Taiwan applied for NATO membership. They are already recognized by most countries as an independent entity and I assume are aligned with many Western goals since they conduct joint military exercises with the US, but China would go crazy over attempts at NATO membership.

    Makes me wonder if there are are any rules to prevent acceptance if a country is attacked because of asking to join? Like I know Ukraine can’t join right now because they’re already at war (despite whatever Russia wants to call it), but I think Taiwan is not officially at war with anyone.







  • I thought the torus shape was the accepted theory? Guess I haven’t been keeping up on this.

    Near the bottom of the article they mention that if the universe wasn’t flat, we would see multiple copies of the universe in the sky. I’m not sure that is exactly true? Given the speed at which the universe is expanding, especially during the early period after the big bang, it seems reasonable that the light from most stars wouldn’t have had a chance to loop back around yet. Even the light from the earliest stars is just reaching us, so I don’t know why they think it would have had time to loop back around multiple times, unless there’s something I’m missing?

    And nothing in the article really touched on the “holes” mentioned in the title. Are they referring to the center of a torus, which isn’t really a hole that we could observe? I don’t get it.






  • I’ve never used TrueNAS, but my experience with ZFS is that it could care less what order the drives are detected by the operating system. You could always shut down the machine, swap two drives around, boot back up, and see if the pool comes back online. If it fails, shut it back down and put the drives in their original locations.

    If you are moving your data to new (larger) drives, before anything else you should take the opportunity to play with the new drives and find the ZFS settings that work well. I think recordsize is autodetected these days, but maybe for your use things like dedup, atime, and relatime can be turned off, and do you need xattr? If you’re using 4096 block sizes did you partition the drives starting at sector 2048? Did you turn off compression if you don’t need it? Also consider your hardware, like if you have multiple connection ports, can you get a speed increase by spreading out the drives so you don’t saturate any particular channel?

    Newer hardware by itself can make a huge difference too. My last upgrade took me from PCIe x4 to x16 slots, allowing me to upgrade to SAS3 cards, and overall went from around 70MB/s to 460MB/s transfer speeds with enough hardware to manage up to 40 drives. Turns out the new configuration also uses much less power, so a big win all around.

    A lot will depend on your preferred workflow, and since you mentioned SolidWorks I assume that means you prefer a more GUI-oriented approach. However as an alternative, if you are comfortable with more of a programming approach, you might look in to OpenSCAD. Most things are done from a more primitive standpoint in how you create each part of an object, but I like having the direct control over every aspect.
