When you saw that 20v on the board I assume that was right next to the charge port? There are often fuses that should be very close to that connector that you can check for continuity on. Usually marked with zeros because they act like a zero ohm resistor.
Even if the fuse is blown that might just be a sign that something further down the line failed but it would be an easy thing to check at least.
I am not exactly an expert at this but it could just be from heat. Do you have a multimeter to check if current can pass through it still?
Either way it seems like this shouldn’t be affecting the laptop when plugged in because it is so close to the battery connector and it looks like the traces are related to the battery connector.
Do you get anything at all (battery/power LEDs) trying to run off of the battery? Is it possible that the charge port failed and the battery is just dead now? Maybe check the battery voltage to see how far drained it is.
Yeah it is pretty bad when an emulator offers a better experience than even a modded Switch.
Easy to load your choice of directory sync tool (i.e. NextCloud Sync Client/Synology Drive Client/etc, or Google Drive/OneDrive if you are on Windows) pointed at your emulators save directory and have your own automatic cloud sync that you have full control over, built in versioning, the works.
Nope, the switch only keeps saves on the internal storage or synced to their cloud if you pay for it. When doing transfers between devices like this there is no copy option only a move and delete.
There are some legitimate reasons they want to prevent this like preventing users from duplicating items in multiplayer games, etc. Even if you got access to the files they are encrypted so that only your user can use them.
I think the bigger reason they do this is there are occasionally exploits that are done through corrupted saves. So preventing the user from importing their own saves helps protect the switch from getting soft modded.
If you mod your switch you can get access to the save files and since it has full access it can also decrypt them, so that you can back them up. One of several legitimate reasons to mod your switch.
FYI the latest SteamOS release (just a couple of days ago) added an option to only charge to 80%.
Cisco c3850-12x48u is about $150 on eBay.
The main problem is the idle power consumption. About 150w with nothing plugged in.
Btrfs is a copy on write (COW) filesystem. Which means that whenever you modify a file it can’t be modified in place. Instead a new block is written and then a single atomic operation is done to flip that new block to be the location of that data.
This is a really good thing for protecting your data from things like power outages or system crashes because the data is always in a good state on disk. Either the update happened or it didn’t there is never any in-between.
While COW is good for data integrity it isn’t always good for speed. If you were doing lots of updates that are smaller than a block you first have to read the rest of the block and then seek to the new location and write out the new block. On ssds this isn’t a issue but on HDDs it can slow things down and fragment your filesystem considerably.
Btrfs has a defragmentation utility though so fragmentation is a fixable problem. If you were using ZFS there would be no way to reverse that fragmentation.
Other filesystems like ext4/xfs are “journaling” filesystems. Instead of writing new blocks or updating each block immediately they keep the changes in memory and write them to a “journal” on the disk. When there is time those changes from the journal are flushed to the disk to make the actual changes happen. Writing the journal to disk is a sequential operation making it more efficient on HDDs. In the event that the system crashes the filesystem replays the journal to get back to the latest state.
ZFS has a journal equivalent called the ZFS Intent Log (ZIL). You put the ZIL on fast SSDs while the data itself is on your HDDs. This also helps with the fragmentation issues for ZFS because ZFS will write incoming writes to the ZIL and then flush them to disk every few seconds. This means fewer larger writes to the HDDs.
Another downside of COW is that because the filesystem is assumed to be so good at preventing corruption, in some extremely rare cases if corruption gets written to disk you might lose the entire filesystem. There are lots of checks in software to prevent that from happening but occasionally hardware issues may let the corruption past.
This is why anyone running ZFS/btrfs for their NAS is recommended to run ECC memory. A random bit flipping in ram might mean the wrong data gets written out and if that data is part of the metadata of the filesystem itself the entire filesystem may be unrecoverable. This is exceedingly rare, but a risk.
Most traditional filesystems on the other hand were built assuming that they had to cleanup corruption from system crashes, etc. So they have fsck tools that can go through and recover as much as possible when that happens.
Lots of other posts here talking about other features that make btrfs a great choice. If you were running a high performance database a journaling filesystem would likely be faster but maybe not by much especially on SSD. But for a end user system the snapshots/file checksumming/etc are far more important than a tiny bit of performance. For the potential corruption issues if you are lacking ECC backups are the proper mitigation (as of DDR5 ECC is in all ram sticks).
They stick 9.81 in for acceleration, so that is presumably for gravity.
I assume you are powering the dock? Many docks require external power before they will pass video.
Does the screen on the deck shut off or stay active?
If the screen stays active that means that it isn’t detecting an HDMI signal through the dock at all.
If the screen shuts off but you get no video through the receiver, you should try hitting the power button one to shut it off wait a few seconds then turn it back on (while plugged in). Even the official dock has issues getting the deck to switch to the external output but putting the deck to sleep and back on gets it sorted out.
If that still doesn’t do it plug in directly to your TV to narrow down the problem (removes the receiver as a variable). Next try a different HDMI cable, and as a last resort try a different dock. If you know someone else with their own deck you can try theirs to eliminate a hardware failure on your deck.
Slows down then freezes sure sounds like an out of memory situation, so to add to yours here they might actually want less swap. Sometimes you would rather hit the oom killer sooner instead of waiting on swap to fill.
Ideally login via SSH from another machine to figure out what is using the memory (hopefully the system is responsive enough for SSH), and if it is your critical programs causing the problem then you should consider a memory upgrade.
In any KDE app you can connect with SFTP in the open file dialog. Just type sftp://user@server/path and you can browse/open/edit files the remote server. ssh keys+agent make things a lot easier here obviously.
This is likely something like a FIDO token/passwordless setup of some sort (i.e. Windows Hello).
The thumbprint would just unlock the hardware device, so the thumbprint itself wouldn’t need to be transmitted to your credit issuer. This gives you full two factor authentication of your identity because you need the hardware device (something you have) and your biometric (something you are). They also often allow pins (something you know) instead of biometrics as the second factor.
I believe so. The package descriptions for most of the ZFS packages in Ubuntu mention OpenZFS, so it certainly appears that way.
You can still create pools that are compatible with Oracle Solaris, you just have to set the pool version to 28 or older when you create it and obviously don’t update it. That will prevent you from using any of the newer features that have been added since the fork.
Well worse than that, Oracle closed sourced ZFS, so OpenZFS was forced to become a fork, and they are no longer compatible with each other.
As for GPL the CDDL license that ZFS uses made sure that code contributions attribute copyright to the project owners, which means they can change the license as they please without having to track down contributors.
You would think with their investments in Oracle Linux and btrfs they would welcome that license change, but apparently they need excuses to keep putting money into Solaris, and their Oracle ZFS appliances instead.
Your $1 has absolutely changed in value by 10pm. What do you think inflation is? It might not be enough change for the store to bother changing prices but the value changes constantly.
Watch the foreign exchange markets, your $1 is changing in value compared to every other currency constantly.
The only difference between fiat and crypto is that changing the prices in the store is difficult, and the volume of trade is high enough to reduce volatility in the value of your $. There are plenty of cases of hyperinflation in history where stores have to change prices on a daily basis, meaning that fiat is not immune to volatility.
To prevent that volatility we just have things like the federal reserve, debt limits, federal regulations, etc that are designed to keep you the investor (money holders) happy with keeping that money in dollars instead of assets. The value is somewhat stable as long as the government is solvent.
Crypto doesn’t have those external controls, instead it has internal controls, i.e. mining difficulty. Which from a user perspective is better because it can’t be printed at will by the government.
Long story short fiat is no different than crypto, there is no real tangible value, so value is what people think it is. Unfortunately crypto’s value is driven more by speculative “investors” than by actual trade demand which means it is more volatile. If enough of the world changed to crypto it would just as stable as your $.
Not saying crypto is a good thing just saying that it isn’t any better or worse. It needs daily usage for real trade by a large portion of the population to reduce the volatility, instead of just being used to gamble against the dollar.
Our governments would likely never let that happen though, they can’t give up their ability to print money. It’s far easier to keep getting elected when you print the cash to operate the government, than it is to raise taxes to pay for the things they need.
The absolutely worthless meme coin scams/forks/etc are just scammers and gamblers trying to rip each other off. They just make any sort of useful critical mass of trade less and less plausible because it gives all crypto a bad name. Not that Bitcoin/Ethereum started out any different but now that enough people are using them splitting your user base is just self defeating
