[Edit] Details on the plan as it stands are here, potentially using one of these heat pumps.

Looking for advice before the weather starts to warm up! I'm running multiple GPUs for dev work in my small home office, and it's pretty much equivalent to having a fan heater running all day. Right now that's actually a bonus, but it really won't be in a couple of months.

The big heat generating components are all water cooled - partly just to fit them in a sensible amount of space, and partly because I figured I'd end up with exactly this problem and being able to physically pipe the heat elsewhere (ideally outside) would probably be necessary. The bit I'm trying to figure out now is how to actually make that happen...

Ideas so far:

• Stick an air duct on the back of the radiator and hang the duct out of the window: straightforward but messy, may be counterproductive depending how hot it is outside and how well I can rig up some kind of baffle between the open window and the duct.

• Put the whole radiator outside and drill a couple of small holes in the wall for the pipes: this was my first thought, but PC radiators and fans definitely aren't rated for outdoor use, and I'm not sure where to start looking for something that would be designed for that while still being suitable to hook up to the computer waterblocks. I'm also concerned about condensation on the electronics if the coolant gets below indoor ambient temperature overnight.

• Set up some kind of actual exterior radiator (or heat pump?) outside, and use a heat exchanger between that and the PC cooling loop: seems more like the "proper" way to be doing this, but it's well outside my area of expertise and feels like there would be a lot of potentially expensive stumbling blocks. Also still has the condensation problem, I think.

• Just crank up the air conditioning: I'm not actually sure if the unit I've got has enough capacity, and it definitely seems wasteful to heat up the air and then use more energy cooling it again rather than dumping the heat directly outside, but maybe I'm wrong there!

I'm in a kind of awkward middle ground: I'm running enough hardware that this is getting to be an issue beyond what you'd get with normal end user setups, and I'm willing to put some money into fixing it (it's affecting my job and my home, after all!), but I'm self employed and nowhere close to the industrial or datacenter scale that tends to come up when searching for solutions.

Has anyone dealt with this themselves, or come across small office/homelab scale solutions that might work?

My memory kit is G.Skill Trident Z5 RGB 32GB (2x16GB) 5600 CL36 Black. The CPU is i9-13900KS on Gigabyte Z790 AERO G.

I noticed that memory price has been dropped significantly so I think I might upgrade to 64GB.

Online information seems to be conflicting regarding XMP and dual/quad channels, so I'm asking for advice here:

1. Can I buy one more of the same kit to upgrade to 4x16GB? Will it affect XMP or dual channel?
2. Can I buy other sticks of the same size (2x16GB)? The leftmost slot is obscured by the CPU cooler fan, so I'll need to either move it up or use low profile one.
3. Can I buy 2x32GB sticks so I end up with 2x32GB + 2x16GB?

From what I understand doing any of those options might cause XMP to not work and it'd be the best (but costly) to have 2x32GB as the only sticks in the system.

Previous topic - https://tildes.net/~comp/1jsx/my_even_smaller_keyboard_upgrade

I'm making this a new topic because this keyboard once again got me to think about a couple of interesting things in regards to both having a smaller keyboard and how to actually make that work. Plus while niche as hell I'd like to contribute some sort of topic to tildes every now and then. For this one i'll be rambling about some of the reasons I've stuck with these things, and the sorts of design concepts it's forced me to think about and problems I ran into (like where the hell the shift key is).

1. Power users and the Nav cluster -

The nav cluster is the Home/End/PgUp/PgDwn/Delete/Insert section and maybe the arrow keys below it on a standard fullsize keyboard. These keys are SUPER useful for text and other sorts of navigation, to the point that it seems most "power user" systems(IDE's or even things like vim, or vimum for browsers) just remap the functionality to somewhere that can be easily reached.

In fact moving the nav cluster and numpad to be somewhere easier to access, so i wasn't constantly moving my hand back and forth, was one of the main reasons I started looking into custom keymaps and eventually smaller keyboards. Being able to trivially hit Home/End without lifting my hands is just so much nicer.

I mention all this to show you the kind of thinking that originally went into me going down this rabbit hole.
In essence:
I wanted to type/navigate faster, oh you can use these keys to be faster, but wait, i'm only a little bit faster and it's MUCH more annoying because I constantly have to move my right hand back and forth, how do I stop that?

Thus i'm always somewhat surprised at how vehemently people can get about remapping keys. Having Up/Down/Left/Right on I/K/J/L with Home/End/PgUp/PgDwn on U/O/Y/H is super intuitive(right handed WASD, with home/end/pgup/pgdwn in line with their corresponding movement) and makes flying around the screen so much easier, and can also open up keybindings that were otherwise used with just porting all this functionality to keys you can easily hit.

2. Chords, and the first major problem -

I'm sure there's a more technical definition but for the purposes of this topic chords are anytime you're hitting one or more keys at once. Shift + a is a chord for A. Ctrl+Shift+Esc is a chord for opening the task manager on windows.

One of the things you don't instantly think about when you get into smaller boards is what chords are popular, and how adding layers to your workflow will affect them. You really want your modifier keys to be accessible at all times, and in a way that makes sense. I don't have a problem that since my Esc key is not on the base layer, the Ctrl+Shift+Esc becomes Ctrl+Shift+Space+Tab for me. To break that down, Ctrl+Shift are on all layers, Space, when held, is the modifier to go to one of my other layers, and on that layer tab becomes esc.

In short, I've added one extra key to the chord, and it doesn't bug me.

What DID bug me, was that with this smaller keyboard, I no longer had room on the left side to put all of those modifier keys. You'll notice that the chord can be easily hit with your left hand alone, and with my previous map, I had shift on the right side. So now I need two hands to hit this chord instead of one. Oh well, right? It's just one chord and I need to use both hands...., whatever?

3. Oh yeah, the mouse......oh shit -
While I do think that more software should be written to allow mostly keyboard interaction, the mouse still serves a useful purpose in my ideal world. Being right handed, I use my right hand for the mouse. Sure I have some mouse functionality bound on one of my layers, but that's not going to replace the speed and precision of the mouse.

And that brings me to Win+Shift+S on windows for taking screenshots. Or more precisely, for selecting an area to take this screenshot....using the mouse.

First off, if you didn't know about this chord and you're on windows, please use it, it's fantastic for those quick "no i mean this" moments where you're trying to send someone a picture of a problem.

Second, this chord SUCKED on my new keyboard layout. On any of my previous keyboards including a normal one, I could hit this chord with just my left hand alone, while I moved my right hand to the mouse to quickly select the area I wanted and then edit it (often drawing red lines around the buttons I needed someone to click on...again....as mentioned in the documentation......).

My new layout had shift on my right hand, and oh dear god did I quickly realize how many other little workflows suck when you need to use both hands to hit the chord and THEN lift up and move it over to the mouse. Most importantly, multiple line/file selection, now required me to move my right hand to the mouse, and my left hand to the right keyboard, so I could hold shift and select things.

Or in overly dramatic terms, lo i had flown too close to the sun and was falling!

4. Wandering in the dark -

For those that for some reason don't have the 5x3 Chiri CE physical layout memorized, here it is (bottom one).

First try:
Move shift to the top button of the left thumb cluster. This was currently tab, but clearly I needed shift on my left hand more. Tab cold go on the right middle, where shift had been, and shift can go where tab was. Problem solved.

No good. That key is often hit with my index finger instead of my thumb, making something like shift+t/g/b super annoying. Hitting that key with your thumb actually requires a shifting of your hands position, and thus feels unnatural.

Worse, the key below it is my space/layer button, so something like shift+ctrl+left, to select previous words(left in this case being space + j), was super uncomfortable to hit. Just moving my thumb up to hit both keys at once did not feel good as I couldn't properly apply pressure and it just felt weird, but I wouldn't be shocked if some people out there are comfortable with that.

Second try:
Ok, we'll just move one of the other 3 thumb keys on the left to the right and put shift there, probably the win key.

No good. Ctrl and Win (or gui/super/meta/whatever) are just as important as shift. That small cluster being close to each other on normal keyboards, so they're left hand control only, means that almost ALL programs assume as much and have built their default hotkeys around it.

Windows window movement and terminal navigation being two of the bigger ones that affected me. Further this still wouldn't solve my win+shift+S screenshot issue, as now i'm just moving the windows key over there. There's no way in hell i'm putting ctrl on the right side because that's also constantly used in assuming its on the left side for various hotkeys, shortcuts, and other behaviors.

Third try:
It was at this point I was entertaining finally looking into homerow modifiers and setting up tap/double tap modifiers instead of hold. I'm still skeptical of how useful any of that is (but being open minded because of course I was skeptical of all of this and now I preach it), and realllly didn't want to go down that road for all sorts of little workflow reasons I was worried it'd collide with.

5. The solution. Pinkies and two shifts -

This stumped for for about two days after I'd decided I just couldn't live with right shift (there were plenty of other awkward workflow things due to having the number layer key be the leftmost thumb on the right pad). I'd really been trying to practice getting used to hitting both thumb keys with my thumb, as I assumed that might be the solution, and unlike basically every other adjustment I've ever had to make for a keyboard, this just felt rough.

So I took a break and just thought about my previous and normal keyboards. Well, again, in those cases, all these chords assume you're using your thumb for one modifier, and your pinky for the other. Sooooo why not just do that?

Thus the solution was born:
MT(MOD_LSFT, KC_X)
MT(MOD_RSFT, KC_SLSH)

For the few of you who don't have your Via/QMK mappings memorized, this just says that if I tap the key in question, type z (or / for the second one), and if I hold the key in question, treat it as if I'm holding the shift key.

So my shift keys are now used by my pinky, just like normally. I have them on Z and /, so I can easily hold either for whatever chord. If I need something like ctrl+shift+z I can just use the right shift, and ditto for ctrl+shift+/.

Even better, this was already my natural inclination. It only took a bit for me to find out just how much faster and easier this was making things, as I already was used to the idea of moving my left pinky downwards to hit shift. In fact, it was even easier than normal. Every now and then I'll get zi instead of I because I didn't hold the key long enough for it to trigger the "shift" function, and I could get really messy and start screwing with how long the keyboard takes to recognize the difference between a press and a tap, but I'm super happy with it.

6. Conclusion -
My wife is right to judge me and I don't care from my superior position in typing valhalla.

I've been having intermittent problems with selecting text. I'm not sure which software it is in, but it is certainly in Slack and IntelliJ. The text I select will often/sometimes not stay selected once I lift my finger up. It will take several times to make the selection last, sometimes swiping in a different direction.

Is it my mouse or the software?

My mouse in made by Inland, model RTM098( J10 ). Probably very old.

I'm looking to buy a Framework 16 in its most powerful Ryzen config. I'm looking at this being the last laptop I need to buy because of its modular design, so I don't mind the heavy initial investment.

I'm looking to shave of $400-500 by buying parts externally, however. I wanted it to be 64GB RAM, with a 4TB OS drive to run Aurora on, and later on a second drive for another non-immutable LTS distro (probably Debian?).

If I can source the same RAM/Storage, is there any reason to actually buy them from Framework? I'm a bit confused by the huge price difference, since I can get the same memory and storage hardware from Microcenter for about $400 less total.

And if anybody has any experience with the Framework 16 as a daily driver, I'd be interested to hear any stories. I'm not getting the graphics module yet, but may down the road to see if it can replace my desktop fully. Drivers should not be an issue as Aurora has a Framework image that contains everything I'll need.

Can someone recommend a KVM that works? I've been looking for a couple of years now.

Requirements:

• 2-port, 1-monitor, DisplayPort 1.4 KVM
• Has a wired push button switch (and cable can be extended if needed)
• Runs at 3840x2160 @ 120 Hz (or 60 Hz)
• Works with HP docking station (HP USB-C Dock G5 for business)
• Works with Classic 101 Black Buckling Spring USB keyboard
• Works with Logitech TrackMan Marble Trackball
• Works with HP laptop and custom desktop build (NVIDIA T1000 GPU)

Anti-requirements:

• Does not intercept keystrokes (or can be disabled)
• Does not intercept mouse scrolling (or can be disabled)
• Does not randomly repeat keys
• Does not block certain keystrokes (e.g., ctrl+shift+t)
• Does not let Windows laptop go to sleep
• Does not require manually re-waking Windows laptop by pushing power button
• Does not require switching back-and-forth to re-establish connectivity to both computers
• Does not take more than 3 seconds to switch between computers
• Does not randomly blank the screen for 1 second
• Does not require unplugging and re-plugging the USB keyboard

Here's the setup showing both computers and the push button switch:

• https://i.ibb.co/5nrDk21/kvm-setup.jpg
• https://i.ibb.co/hFsjT3S/kvm-switch.jpg

I have tried:

• IOGEAR GCS62DP (almost perfect; kills keyboard after 60 swaps; RMA'd)
• DiamondTiger KVM Switch EDID 8K@60Hz, 4K@144Hz, DP 1.4 (repeats keys, blanks screen, has screen tearing, and many other issues)
• CanadaComputers iCAN HDMI USB KVM Switch 2x1 with Switch Extension 4K 60Hz (completely blocks certain keystrokes)

Wendell's Level1Techs Store offers a highly recommended KVM, yet lacks a wired toggle button.

What other KVM switches are available that "just work" and have a wired push button for switching?

The next KVM I'm thinking about trying:

• GiantMatrix with LINDY EDID Emulator

ATEN also has a switch, which is on par with the IOGEAR (4K @ 60 Hz, no EDID):

• 2-Port USB DisplayPort/Audio KVM Switch

Hey all, I'm interested in going down the rabbit hole with Ubiquiti equipment or other manufacturers, more specifically with access points, routers, and a switch. I want to ween off my ISP-supplied all-in-one equipment as their newer hardware limits basic features such as port forwarding, and I'm interested in re-enabling my self-hosted software. Wi-Fi standards have been moving pretty quickly, as have hardware. What setups do you have established in your homes?

I don't really have a budget in mind, and have a 2.5GbE port I'd like to utilize for media consumption over LAN.

Hi everyone,

So, I have a DS923+ with 4GB of RAM and while it is running fine most of the time with my Docker containers, I guess everything could be more fluid (e.g. scrolling on Jellyfin while it is loading info / images).

Since the Linux OS uses free RAM as cache, I was looking to buy an extra stick of RAM. I was thinking of buying a 8GB of RAM which in total my system would then have 12 GB. Not sure if overkill, but still, I run a few containers.

I’ve actually searched on the Synology subreddit, but everyone is basically buying 16GB of RAM or maxing out the GB allowed for the RAM on the DS923+. So, that is the reason why I’m asking here.

I know that Kingston has some 8GB RAM sticks which should work with DS923+ but it seems they are blacklisted by Synology, so it seems you will always have a warning on the notification list which I wanted to avoid. :/ But on that list (see here: Ram list), it seems the 8GB RAM that Synology uses is sourced from Innodisk or Adata, so you shouldn’t get any warning there. Sadly, I can’t find them anywhere for sale. Even when I contacted the companies directly.

In conclusion, has anyone bought a 8GB ECC RAM for the DS923+ which doesn’t give a DSM warning?

Thanks everyone in advance!

Cheers!

Hey everyone!

Sorry if this is a long post, but I've done my research and I would like to make a few questions.

I've decided that I would like to buy a NAS mainly to storage all of my documents, photos and videos, so that, I can access them from multiple devices and also use it to upload important documents to Backblaze B2. Then, I've actually discovered that I can install a few Docker containers and I could use it as a media server (Jellyfin) and serve the content to my Apple TV (neat!).

I considered a QNAP (better hardware for the price) but everyone recommends Synology instead (because of the stronger security and better overall software), but to be honest, I'm not sure what should I get.

My budget would be to buy a NAS (without counting the disks) below €1000. Ideally, €500-600 but I don't mind stretching to the €700 mark, if it is really worth it.

Spoiler alert: I think, it should be the DS920+ (4-bay) or the DS1520+ (5-bay). I think a NAS above 4-bay is better for future-proofing.

Looking here in Germany at price comparators, I could buy the DS920+ for €663 and the DS1520+ for €750. But these prices seem to be at an all-time high :(

Questions & Assumptions:

0. I'm not sure if the price difference of about €100 is worth the premium to get the 5-bay model. There are only two differences between these two models: The 5-bay has one extra slot, and it has 4x 1 Gbe LAN ports instead of 2x 1 Gbe. All the rest is the same. What is your opinion?

1. I've read that if you run a few containers (~10) it consumes quite a bit of RAM (~3 Gb), so it should be ideal to have at least 8 Gb. This is the reason I've said that I think I can only choose the DS920+ or DS1520+. Looking at official Synology resellers, these models, seem to come already with 8 Gb, and they are within my budget. Is my research wrong?

2. These two models, have an encryption engine. I think this is necessary to encrypt my files before sending them to Backblaze, or?

3. A lot of people seem to say to simply pick Synology's hybrid RAID setup called SHR-1 or SHR-2. I would go the easy way here and pick one of those two. Would you think that is a bad idea, and it is better to pick a specific (standard) RAID? I've read about the long long long RAID rebuild that could happen in some situations, and picking the "right" RAID could decrease the rebuild in days (or weeks!!!!).

4. In case, I choose a NAS model with Nvme cache slots, most people say it is not worth it to use if you are not running Virtual Machines and the SSD’s "burn" really fast. I have no interest on VMs.

5. Most people say to pick an Enterprise (Server) HDD instead of a NAS HDD mainly because price is similar in some cases and Enterprise has longer life and warranty. I should also pick a CMR HDD which is helium filled. 5400 rpm would be preferable to 7200 rpm because of the noise. Sadly, all Enterprise HDD's and most of NAS HDD's are 7200 rpm. Is the noise difference that big? The NAS will be in our living room.

6. Is 8 TB still the best cost per Terabyte?

7. I was extremely sad to hear that the Hitachi hard drive division was bought by WD. I've had lots of misfortune with WD drives (and let's not forget the debacle with the SMR and CMR drives) and I would prefer not to give money to them, but, nevertheless, I'm still tempted to buy the Ultrastar drives that belonged to Hitachi. Does anyone know if WD kept the components, manufacturing processes, staff, etc., that made these brilliant disks?

8. Following the HDD topic, what is your experience with Seagate or Toshiba drives?

9. These two NAS models have the same Intel Celeron CPU, which supports hardware transcoding. To be honest, I don't know in which cases would that happen. It seems if I use Infuse on the Apple TV it would never transcode (and instead direct play) because Infuse would do the transcoding in software. Should I take in account that hardware transcoding is a must-have or a nice-to-have?

10. Would you recommend having a CCTV system connected to the NAS? Should I dedicate one entire HDD just for the NVR system? Would a standalone NVR device be better?

11. My last question is: Should I just wait for the new model of the DS920+ or DS1520+? The 20 means it was launched in 2020 (in Summer specifically) and it seems Synology refreshes the model every two years., that means, a new model would be available in Summer this year. Most people say it is not worth the wait because Synology is very conservative in its model updates/refreshes. People are saying that a better CPU will be of course available (do I even need that for my use cases?) and probably upgrade the 1 Gbe LAN ports to 2.5 Gbe or 10 Gbe (10 Gbe I really doubt it). I've read that a 4K stream does not fill a 1 Gbe bandwidth, and you could theoretically have three 4K streams in a single 1 Gbe connection. If all else fails, I could just do a link aggregation of the two ports to be 2 Gbe, or?

12. Anything I'm forgetting? Should I be careful with something in particular?

I know I should buy a UPS too, but I think I'll create a separate post regarding this topic because I would also want a recommendation regarding a UPS for my other devices.

I know that I could actually build my own NAS and use Unraid for the OS. Furthermore, I'm just at a time in my life with too much on my plate (baby and small child) and having something that just works is preferable. When they are older and more independent, I'll have more time to investigate this option :)

Again, sorry for the long post. Thank you everyone!

Hello everyone,

I usually do my own research, and then I try to find multiple matching results and afterwards, read specifically in detail about each recommendation, but, I have to be honest that for UPS recommendations that I’ve seen, it seems to be a very personal recommendation depending on the wattage and connected devices.

First of all, most people recommend CyberPower or APC, but I’ve also seen some recommendations for Eaton. Is there any other brand that I should be looking into?

The devices I would like to connect to a UPS would be: desktop, TV, Apple TV, NAS, router and probably my Nintendo Switch.

There are some general things I've found out while searching that I think I would like some confirmation:

• I actually think I should buy two UPS's, or? I think just one for the desktop and another one just for the remaining devices, since the desktop uses a lot more wattage.
• Pure Sine Wave: It does not matter for smaller stuff (routers, etc) but it seems that anything above 70 W, it should use a UPS with this. So, that would mean I need pure sine wave, since my desktop and TV definitely use more than 70 W of power.
• Some people said to search for a UPS with line conditioning so that you always get a perfect sine wave. Would you agree?
• USB connection (not a faux USB!) so that the NAS detects the power failure and shuts down gracefully.
• It is important that the UPS has removable battery for better longevity.

How would I choose a UPS? Do I need to see the total wattage of all my devices and then pick the UPS accordingly? Anything I'm missing?

My budget would be up to €100 or €150 in case it is really worth it.

Thank you in advance for all replies.

This is a total longshot. I moved away from a WD My Cloud EX4100 w/ 3x WD Reds to a new box. I bought two more drives for the new one to make the move easier.

After the move I took the drives out to format them only to find that each 4TB drive shows a partition of 1.8TB on any other system (diskpart with W10 LTSC, Disk Utility MacOS, and GParted with Ubuntu.) Inside the EX4100 the drives show their full capacity.. and I just don't get it.

I reached out to their support, but I don't expect much of a response.

Anybody have any idea why the heck this could be happening? This seems crazy. I don't mind buying more drives, but it seems like a waste when I've got 12TB just sitting there.

Right now I've got a shitty WD EX4100 and everything was sort of running along nicely with docker and all, but today it rebooted and decided that it didn't want to do anything with docker anymore. I got the thing before I got into Linux and its time to move on.

Someone locally is selling the following for $250CAD

• Quad core Celeron @ 2Ghz
• 8GB RAM
• Fractal Node 304 case
• 2x WD 2TB Red 3.5" hard drives
• 120GB Kingston SSD
• 700 watt semi-modular power supply

All I run are the following:

• nzbget
• sonarr
• qbittorrent (but I'll switch to a better one)
• serve up content to my HTPC (running Kodi, so no transcoding or anything)

I don't need the drives that come with it. I'll be putting in 4x 4TB WD Reds. Right now the box is running Open Media Vault 6, so I'll give that a swing, otherwise it'll just be Ubuntu server.

How does this sound? I'm not opposed to spending some money on a new NAS, I just want something simple that I don't have to fuck around with too much.

I ended up going with the HP Proliant

OS: Ubuntu 20.04.3 LTS x86_64
Host: ProLiant ML310e Gen8
Kernel: 5.11.0-43-generic
CPU: Intel Xeon E3-1230 V2 (8) @ 3.700GHz
GPU: 01:00.1 Matrox Electronics Systems Ltd. MGA G200EH
Memory: 32GB

It's pretty good so far. Thanks everybody!
