content: FreeCAD can be used in 2D "manner" if one likes to. The Draft Workbench is made for that purpose and now if one day you would like to move to 3D you are not far. Word of warning! FreeCAD is not so easy or straight forward to start with but once you have completely rotated your head 2-3 times it does what you wish. I have gone the hard way with it but would not now change.

Battery Current Capacity Flactuation Dynabook Satellitte Pro C50E10D - Page 1

content: The dynabook satellite pro current battery capacity changes erratically from 79% to 19% on different days and so off power lasts between 3 hours to 20 minutes. Original Capacity in 2020 was 45600 and today it is 8800 mWh. Last week it read 51%. I have tried resetting it and am thinking a new generic battery is proper or else a new laptop. It is the inconsistent reading that confuses me. Had it been constantly at 19% day in day out then that tells me it is finished.

content: I'm no expert and I don't know if dynabook satellite pro uses removal battery, but this symptom is exactly what I got with some very old machines that I still use. My situation was caused by "bad electrical contact" between battery and device. This issue may be the same issue you got, but may be not...Example 1In the case of my Treo 650 (I still play video poker on it), the spring contact(s) loosing elasticity due to age. It was no longer able to press against the battery electrical contacts hard enough to ensure good electrical contact. I merely taped some paper (cut pieces of business card) to the non-contact side so less space left between the battery contact side and the spring doesn't have to push that hard. In the case of the Treo 650, when I was using it as phone almost 2 decades ago, some thinner SIM card also need a piece of business card to ensure good contact.Example 2In the case of my ASUS zenphone2, it was the battery connector to the phone's "mother board" no longer secured. So electrical contact is at time good but at time not working well enough. Sometimes it goes from 30% down to 0% (shut down) in mere seconds. At times, it stays on 50% no matter what I do. After trying many other ways, the one that works well for me is layers of electrical tape: multiple layers until the "right" thickness so that the phone's screw-on back frame push up nicely against the electrical tape layers which holds the plug down. This method held for about 2 years until the battery was so worn out I had to replaced the battery.Example 3In another bad-contact case: This happens to my JUUL (e-cigarette) a lot -- dirty contacts. I use alcohol with q-tip to wipe both sides (charger contact to JUUL device contact, and/or JUUL refill pod to JUUL device) and life is good again...Hope this helps....

The lack of installation/maintenance is the appeal of running stuff with containers though.At least that's the argument I keep hearing.In the time since I've made my first post asking for recommendations I've found that it's...marginal at best.I do like how quickly I can spin up and destroy VMs in Proxmox though. I used to use Vultr for that task, for trying new things. I like owning my own hardware for that purpose now though, much cheaper, and zero cost to just store a stopped container (aside from storage).I really like spinning up a container for setting up toolchains for compilation/development. Especially for firmware. Like I've set up CircuitPython containers, Armbian containers (not firmware, but the concept is the same), and so on.Keeps things consistent and clean. Plus checkpointing with pinned backups seems nice.

"no noticeable difference" in terms of normal desktop use.A 4K monitor + a 1440P ultrawide at 60FPS and it's snappy and fast for desktop use.Gaming. No. Well, if you want to game in 1080 at Med to Low settings maybe. However, everything else including 4K YouTube content, half dozen browser windows, it's practically the same. I have seen the 5600G paired up against a CPU + Gtx1030 and it holds it's own, so similar experience. This being a 5600H (the laptop variant) will be more TDP limited.Pinned, on big loads, the 5800X will run rings round the 5600H, but on basic desktop use, I doubt you'll notice.The "big" PC uses 100W idle.The "pint" PC usage about 20W.The entire office with this PC and a 4K HDR 42" Monitor is around 125W.Put it another way, it's a pretty decent laptop is a pint sized box with no screen for £370.

content: The other day I was pondering if I could use the memory in my GPU for something like the 95% I am not playing games or using blender. So I was thinking you could use CUDA or openCL to allocate memory and try to make it into a device in Linux or something. So I searched for it and it turns out it already has been made for Linux. My RTX 3060 has a half decent amount of VRAM (12G) and my system has 32GB.It exists at this place:https://github.com/Overv/vramfsSo immediately I would expect something that reads and writes a lot of files all the time could benefit from that, or something that stream captures, like video recording may be good with that. In this case, the memory is mounted on the filesystem at some directory as root. I have created a ntfs image in that ramdisk and loopback mounted it as mod 777.You can just say 4G in this photo but I didn't read the fine print at that time.

If you can measure the kWh over a week or so, with and without the video RAM disk, that would be interesting to compare.I suspect making use of the video RAM will keep the video card in higher power modes. A big video card can easily double the consumption of the entire rig, and this might be visible on the electricity bill.

Strange, intermittent behaviour of EVGA Z370 Classified K motherboard - Page 1

content: Hi:I used to be an IT tech, and still dabble. But let's assume I have next to zero electronics knowledge.For quite a while now, I've been troubleshooting an EVGA Z370 Classified K motherboard. The first one, out of the package was DOA (Bravo EVGA!). The replacement was fine for about 2 or 3 years, then a strange thing started happening. It would INTERMITTENTLY not power on. 5VSB light is on. The onboard power light lights up. But no fans, won't power on.Here are the troubleshooting steps I've tried:- Swapped out for another (quality) PSU. Both PSUs test good via PSU tester and multimeter. Second PSU is brand new. Different model, made a few years later.- Tested the power switch/shorted the power switch terminals with a screwdriver.- Tried different PSU cables.- Tried different CPU.- Tried stripdown method. Disconnected everything but power cables.- Tried removing it from my surge protector and plugging straight into the wall.** Tried resetting to hardware factory defaults. This WILL make the machine boot every time, but will not prevent it from being required to make the machine boot the next time.This is driving me nuts. Sometimes the board will boot reliably for months and months. Then suddenly, I wake up one morning and it won't boot. I should add that, as far as I've tested, power is very stable in my home.The EVGA support I've been working with is baffled.Anyone have any ideas?

content: If you're using Windows a crapton of telemetry is being collected already, in comparison what Intel does is insignificant.That said, still concerning and a general trend which is plaguing even open-source software now. (Sure with OSS you still have the opportunity to know exactly what is being collected, and - usually - have a way of opting out though.)

content: The two options I can think of are:1. research the issue, and see how to turn off intel graphics driver "telemetry". such instructions also exist for nvidia. haven't looked into amd graphics drivers. usually, in the game of war, one side turns on telemetry, and another side figures out how to turn it off. Just about every update or new version of some software now has a form of telemetry in it; sometimes the update "turns the telemetry" back on, even if you do turn it off.2. install anybody's free firewall software that explicitly blocks outgoing comms (from telemetry), and has the "learning" feature that both blocks outgoing comms and tells you about each occurance, giving you the opportunity to allow/disallow it. This generally catches all outgoing telemetry, and once you've been made aware of it, you can block it.The latter item protects you from everyone's telemetry, as it is a challenge to figure out whether telemetry has been turned on in a recent version or update of some piece of software, and you are now up to 10's or 100's of software packages on your given pc or OS build.Hope this helps ...

Cleanest and probably best results would be just to reload the darn thing with the factory install disk. Some ASUS model has a hidden restore partition with the factory software recovery in that partition. ASUS support site may have instructions and user manual for your model as well as "how to restore" info. You could get some help on how to reload the factory software for your model there.

content: To avoid it happening in future, install Linux as your OS then have a virtual machine running Windows specifically for any programs you need which are Windows only and can't un under Wine. If the VM gets infected you can always delete it, or roll it back to an older version. And the VM probably would never need to go online anyway. This setup also protects you against M$ messing up your system with a feature update of dubious quality.

iPhone X Not Alerting About New Emails - Page 1

timestamp: July 21, 2023, 01:24:03 pm
content: I'm uncertain if asking an iPhone question on this site is appropriate, so I apologize in advance.My iPhone X decided to stop alerting me about new emails. Previously it would show a preview of the email when the phone was locked, it would play a sound, and also play a sound when new emails arrived while using it.Suddenly (maybe after an update), it stopped doing this. It still receives email, but only shows the number of unread emails on the email app icon without alerting me.I've checked all the notification settings, notification settings in the mail app, all three banners are turned on, reset the phone, and performed the following because I believe I performed these steps one time when the same issue occurred: turned off email notifications, turned off the phone, turned on the phone, and turned on notification settings.Also, I have the latest update (a recent update maybe last week didn't resolve this issue).Has anyone else had this issue and/or know how to resolve it? One article states to delete the mail app and reinstall it, but I'm reluctant to perform that due to possibly losing my emails along with spending a great deal of time resetting my email stuff. Resetting the phone to factory also seems like a risky step, so I'm against this step as well.

I use NAV 360 and I disabled this app to access the Internet… well, this app is not the only one,it spreads also in few different locations including exec file.In summary, I’m wondering if anybody else has done extended resource about safety of using “AOMEI Backupper”?Is it safe?

content: I have an Ubuntu 22.04.2 system with 2 disk RAID-1 for the data disk. I use this as my primary NAS. Setting this up was easy: mdadm to create a raid, make a filesystem, and mount. Now, I have to take these disks and move it to another system in 1 of 2 ways. Can someone give me a hand on this?1) One way I might do is to take two of these as-is and move it to another system. Is there meta-data of some sort that I need to recreate/move/worry-about? Or just move them physically and md0 will magically show up?2) Another way I might do is to break the mirror and move just one disk. I know of mdadm break command. Then what else do I need to do? Do I need to do anything with the filesystem? Again, is there meta-data for disk arrangement, except for fstab?Thanks!P.S. This is a software raid. I'm using onboard SATA ports for my setup.

content: iirc mdadm is software raid. This should be transferrable to any supporting platform, and since it's raid 1 any one of the disks should suffice.Synology uses this for their platforms, and if the filesystem is compatible you can migrate entire volumes to new servers or even recover with linux.If you have a sufficiently featured distro like Mint it will even auto mount them.But I've never done a migration like you want to...In all cases, making backups is never a bad choice.

There was a small arrow thingy that I just hadn't noticed, but geez. Seriously the window isn't that big, why not make it so all 5 tabs are in view by default?Anyway, on that tab was a listing for many output devices (most of which were unavailable), setting it to "Digital Stereo (HDMI) Out" fixed the problem. Not sure why "Analog Stereo Out" wasn't giving stereo out, or rather both channels to the left side, but I'm not gonna worry about that now.
