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

I just did a playthrough recently and I think it holds up pretty well. A lot of wasted time on little cutscenes like opening Atla/boxes, and switching characters that gets quite annoying, but gameplay was fine.

One or two bosses that are difficult but a little leveling up, or wiki hints on how to cheese them, and they are a piece of cake. Once you hit the ship dungeon and have easier access to backrooms (since you can buy the fish to enter them) you can grind for gemstones and you end up being able to one hit almost everything from there on out.

Grinding gets a bit boring after a while, I'll admit I enabled some fish point cheats in my emulator after I had one character with a maxed out weapon. Clear that I could easily do it myself but wasn't going to waste that time to upgrade the other weapons I wanted leveled up.

Well if you rephrase it for a normal car it doesn't sound so absurd. "If your hood won't latch the car won't let you drive at highway speeds?"

A failed latch on a front compartment can be very dangerous because it catches the wind if it opens suddenly at 60+mph. At best you are blinded, or it gets torn off to go flying into a car behind you.

As such, highway speeds should be restricted if the latch is malfunctioning. The real problem here is that Tesla doesn't like dealers because they want that middleman money for themselves, so you often have to drive quite the distance to get it repaired. If this were a vehicle from any of the other major manufacturers most people are probably only a few miles from their nearest dealer.

Normal cars have two hood latches. Your primary latch (that you open with the hood pull in the car) and a secondary safety latch (when you reach under the hood to open it fully) so this problem is an extremely uncommon problem for a normal car.

But since this is a frunk it gets opened a lot more for storage and users would probably not be very happy about having to deal with the secondary latch on a regular basis. So they have motorized those latches for ease of use, and motorizing them adds a lot more points of failure.

Docker(/Compose) can do mounts directly to the container as well.

https://blog.stefandroid.com/2021/03/03/mount-nfs-share-in-docker-compose.html

https://docs.docker.com/engine/storage/volumes/#create-a-service-which-creates-an-nfs-volume

I've used NFS mounts with docker compose before but I see the second link also includes an example for CIFS as well.

Named volumes are often the default because there is no chance of them conflicting with other services or containers running on the system.

Say you deployed two different docker compose apps each with their own MariaDB. With named volumes there is zero chance of those conflicting (at least from the filesystem perspective).

This also better facilitates easier cleanup. The apps documentation can say "docker compose down -v", and they are done. Instead of listing a bunch of directories that need to be cleaned up.

Those lingering directories can also cause problems for users that might have wanted a clean start when their app is broken, but with a bind mount that broken database schema won't have been deleted for them when they start up the services again.

All that said, I very much agree that when you go to deploy a docker service you should consider changing the named volumes to standard bind mounts for a couple of reasons.

• When running production applications I don't want the volumes to be able to be cleaned up so easily. A little extra protection from accidental deletion is handy.

• The default location for named volumes doesn't work well with any advanced partitioning strategies. i.e. if you want your database volume on a different partition than your static web content.

• Old reason and maybe more user preference at this point but back before the docker overlay2 storage driver had matured we used the btrfs driver instead and occasionally Docker would break and we would need to wipe out the entire /var/lib/docker btrfs filesystem, so I just personally want to keep anything persistent out of that directory.

So basically application writers should use named volumes to simplify the documentation/installation/maintenance/cleanup of their applications.

Systems administrators running those applications should know and understand the docker compose well enough to change those settings to make them production ready for their environment. Reading through it and making those changes ends up being part of learning how the containers are structured in the first place.

For shared lines like cable and wireless it is often asymmetrical so that everyone gets better speeds, not so they can hold you back.

For wireless service providers for instance let's say you have 20 customers on a single access point. Like a walkie-talkie you can't both transmit and receive at the same time, and no two customers can be transmitting at the same time either.

So to get around this problem TDMA (time division multiple access) is used. Basically time is split into slices and each user is given a certain percentage of those slices.

Since the AP is transmitting to everyone it usually gets the bulk of the slices like 60+%. This is the shared download speed for everyone in the network.

Most users don't really upload much so giving the user radios equal slices to the AP would be a massive waste of air time, and since there are 20 customers on this theoretical AP every 1mbit cut off of each users upload speed is 20mbit added to the total download capability for anyone downloading on that AP.

So let's say we have APs/clients capable of 1000mbit. With 20 users and 1AP if we wanted symmetrical speeds we need 40 equal slots, 20 slots on the AP one for each user to download and 1 slot for each user to upload back. Every user gets 25mbit download and 25mbit upload.

Contrast that to asymmetrical. Let's say we do a 80/20 AP/client airtime split. We end up with 800mbit shared download amongst everyone and 10mbit upload per user.

In the worst case scenario every user is downloading at the same time meaning you get about 40mbit of that 800, still quite the improvement over 25mbit and if some of those people aren't home or aren't active at the time that means that much more for those who are active.

I think the size of the slices is a little more dynamic on more modern systems where AP adjusts the user radios slices on the fly so that idle clients don't have a bunch of dead air but they still need to have a little time allocated to them for when data does start to flow.

A quick Google seems to show that DOCSIS cable modems use TDMA as well so this all likely applies to cable users as well.

They are from the Lemmynsfw instance. Probably automatically applied to any post coming from that instance.

I am assuming this is the LVM volume that Ubuntu creates if you selected the LVM option when installing.

Think of LVM like a more simple more flexible version of RAID0. It isn't there to offer redundancy but it take make multiple disks aggregate their storage/performance into a single block device. It doesn't have all of the performance benefits of RAID0, particularly with sequential reads, but in the cases of fileservers with multiple active users it can probably perform even better than a RAID0 volume would.

The first thing to do would be to look at what volume groups you have. A volume group is one or more drives that creates a pool of storage that we can allocate space from to create logical volumes. Run vgdisplay and you will get a summary of all of the volume groups. If you see a lot of storage available in the 'Free PE/Size' (PE means physical extents) line that means that you have storage in the pool that hasn't been allocated to a logical volume yet.

If you have a set of OS disks an a separate set of storage disks it is probably a good idea to create a separate volume group for your storage disks instead of combining them with the OS disks. This keeps the OS and your storage separate so that it is easier to do things like rebuilding the OS, or migrating to new hardware. If you have enough storage to keep your data volumes separate you should consider ZFS or btrfs for those volumes instead of LVM. ZFS/btrfs have a lot of extra features that can protect your data.

If you don't have free space then you might be missing additional drives that you want to have added to the pool. You can list all of the physical volume which have been formatted to be used with LVM by running the pvs command. The pvs command show you each formatted drive and if they are associated with a volume group. If you have additional drives that you want to add to your volume group you can run pvcreate /dev/yourvolume to format them.

Once the new drives have been formatted they need to be added to the volume group. Run vgextend volumegroupname /dev/yourvolume to add the new physical device to your volume group. You should re-run vgdisplay afterwards and verify the new physical extents have been added.

If you are looking to have redundancy in this storage you would usually build an mdam array and then do the pvcreate on the volume created my mdadm. LVM is usually not used to give you redundancy, other tools are better for that. Typically LVM is used for pooling storage, snapshots, multiple volumes from a large device, etc.

So one way or another your additional space should be in the volume group now, however that doesn't make it usable by the OS yet. On top of the volume group we create logical volumes. These are virtual block devices made up of physical extents on the physical disks. If you run lvdisplay you will see a list of logical volumes that were created by the Ubuntu installer which is probably only one by default.

You can create new logical volumes with the lvcreate command or extend the volume that is already there. Or resize the volume that you already have with lvresize. I see other posts already explained those commands in more detail.

Once you have extended the logical volume (the virtual block device) you have to extend the filesystem on top of it. That procedure depends on what filesystem you are using on your logical volume. Likely resize2fs for ext4 by default in Ubuntu, or xfs_growfs if you are on XFS.

FYI the latest SteamOS release (just a couple of days ago) added an option to only charge to 80%.

The problem is that on top of the pins occasionally not making good contact on these new connectors, Nvidia has been cheaping out on how power is delivered to the card.

They used to have three shunt resistors that the card could use to measure voltage drop. That meant that the six power pins were split into pairs and if any pair did make contact the card could detect it and prevent the card from powering up.

There could be a single pin in each of those pairs not making contact meaning that the remaining pins are being forced to handle double their rated power. It is unlikely that you would lose one pin on each pair so that is an unlikely worst case, but a single pin in a single pair failing could be fairly common.

But on the 40 series they dropped to two shunt resistors. So instead of three pairs, they can only monitor 2x bundles of three wires. Meaning the card can only detect that the plug isn't plugged in correctly if all three wires in the same bundle are disconnected.

You could theoretically have only two out of six power pins plugged in and the card would think everything is fine. Each of those two remaining pins being forced to handle three times their normal current.

And on the 5090 FE they dropped down to one shunt resistor... So five of the six pins can be disconnected and the card thinks everything is fine, forcing six times the current down a single wire.

So the point of these fused cables is to work around a lack of power monitoring on the card itself with cables that destroy themselves instead of melting the connector on your $2000 GPU.

Cisco c3850-12x48u is about $150 on eBay.

• 802.3bt (60watt) PoE on all ports
• 36x 1gig rj45 ports
• 12x 1/2.5/5/10gig rj45 ports
• Has a module slot that you can add 4x or 8x (8x is rare so expensive) 10gig sfp+

The main problem is the idle power consumption. About 150w with nothing plugged in.

In the US it's just like getting your regular license. A written test first which gets you a permit to ride (restrictions on that depending on the state you are in, like no riding after dark, no highways, no passengers, etc).

Then you take the road test (or take a class) which gets the full endorsement added to your license.

But yeah I would think on private property you should have been safe.
