The recent emergence of Nightshade, an algorithm that allows to create poisoned data for confusing image-generating AI models, has given new life to the discussion on adversarial attacks on such models. This discussion is also influenced by ethical and social considerations, as such attacks may provide a way for artists, content creators, and others to fight back if they feel treated unjustly by the fact that AI models use their content without permission, but could also be used with bad intentions.

Now let’s take a look at Nightshade, an algorithm that aims at overcoming those disadvantages. For that, Nightshade uses two key concepts: It creates images that have the maximum effect on the model (which leads to a need for fewer images in total) and that are indistinguishable from non-poisoned images for humans.

First, how to get the maximum effect out of the images? In theory, you would want to use those images, that lead to the biggest change of the gradient during the training. However, to find out which images those are, you would have to observe the training process, which you can’t do, in general. The authors of Nightshade propose a different solution though: You take an image, that has been generated by the model you want to poison. That is, if you want to have cat images labeled as dogs, you prompt the model with a simple prompt like an image of a cat. The image it creates will be a very typical representation of what the model understood to be a cat. If this image is seen in training, it will have a very high influence on the understanding of the concept cat (a much higher than rather untypical images of cats have). Hence, if you poison that image, you will get a very large effect on the model’s training.

Second, we said that Nightshade’s images should be indistinguishable from non-poisoned images. To reach this goal, Nightshade takes natural images and applies a perturbation (i.e. a small change in the pixel’s values), until the image is perceived differently by the model. Continuing with our dog vs. cat example from above, we would take an image generated by the model that shows a cat. This image we refer to as the anchor image or xᵃ in the upcoming formulas. Next, we take a very typical image of a dog, which we refer to as xₜ. To this image xₜ, we now add the perturbation δ s.t. it optimizes the following objective:

TL;DR - LG C4 to get 144hz (up from 120hz), will likely *not* be featuring a MLA panel, which will continue to be a G series exclusive.

Easy skip for CX/C1/C2/C3 owners, if confirmed. Unless they bring back 120/144hz BFI, maybe.

All I want is a bright enough panel and BFI so I never have to see the judder again.

C9 still more than enough in lieu of that

Why did they remove 120hz BFI from recent models anyway?

Because woke.

Yay, I figured out how to do port forwarding on my Fortigate! It honestly wasn't hard, just some different concepts and I couldn't get the VIP with the forwarding rules to show up in the firewall policy if I added an ipv6 address to the VIP. I might look into that another day.

Next thing on the docket is to get a VPN IPsec tunnel working so that we can use things like Moonlight/Sunshine when away from home and without having to install third-party software on our machines.

Also, I gave up on VDOM as that is too inconvenient for home usage. However, I am looking at using VLANs for a similar function and it looks like I need some managed switches that can handle VLAN-tagging if I want devices I want on different VLANs to be connected to the same physical switch? Not sure on this one. Need to familiarize myself with it all some more before buying anything as I would need to replace at least two switches in the house.

Oh come on....

Anyone know of an easy way to test if my ISP is blocking a port? I am trying to setup an IPsec VPN on my router and it apparently uses a default port that is often blocked by ISPs and the instructions to change the default port on the router aren't the best: https://docs.fortinet.com/document/fortigate/7.4.1/administration-guide/33578/configurable-ike-ports

Ping the IP and port over your cellphone over LTE? iOS has terminal / command line apps.

That makes too much sense. I really need to fucking sleep.

So, I figured out the issue with the VPN stuff. the ISP modem wasn't correctly set to IP passthrough mode once I switched to my new router. Fixed that issue and now it works as it should.

so it was a double NAT issue?

... i should have thought to suggest checking that

By diehard Go To Postso it was a double NAT issue?

… i should have thought to suggest checking that

It's either double NAT, DNS, or permissions. :v

Like what just happened with me getting Plex fully configured. Was getting an error that Plex couldn't auto-convert and play a video because a codec could not be found or installed. It was because the permissions of the user/group that the Plex container was running under had modify but not full control permissions of the external data volume its configuration was kept in. The codec was being downloaded as a zip file but it had trouble assigning execute permissions to either the zip file, a .tmp file it created, or something else.

I fixed it by creating the appropriate user/group in the host system, creating a new ZFS dataset just for the configuration volume, and creating a new Samba share for that dataset (so I can backup and manually manage the files), and applying the permissions for the user/group to the dataset. Rather simple fix, but assigning permissions for containers that need access other files on the file system is still a little annoying.

The result, according to Migicovsky, is a third-party implementation of iMessage that is actually secure: Beeper doesn’t see your messages, your contacts, or your Apple ID password. (It doesn’t even need you to log in.) It is, he says, just connecting to Apple’s servers like an iPhone would.

Migicovsky knows that security will be the big question on potential users’ minds. To address concerns, Migicovsky says Beeper’s iMessage code will be open source for others to review. Beeper’s CTO, Brad Murray, also spent some time trying to break open the system as if he were an attacker and is publishing his findings.

The bigger question may be how long Beeper Mini can survive. Migicovsky believes he’s on the right side of the law (he points to a copyright carveout for reverse engineering and says there’s no Apple code in Beeper Mini); and he believes it’d be too difficult for Apple to cut Beeper off without also breaking iMessage for legions of genuine Apple devices. I’m not so sure on either count — Apple is deeply protective of iMessage as a lock-in mechanism for the iPhone, and it’s hard to imagine the company ignoring the spate of third-party iMessage solutions forever.

Wonder if Apple will shut him down

I suppose if it’s imitating an Apple device well enough, it’d be hard to patch out without an OS update, and that might be an issue for older iPhones?

my friends have been using beeper for a while. mainly for whatsapp and signal in the same app tho.

Yay, got a dns server running on my fortigate. Now to figure out why my partner’s Windows desktop is the only machine that isn’t responding to pings.

If anyone is or might be in need of smart plugs - to make dumb appliances (somewhat) smart and / or monitor electricity consumption - I very much recommend going with plugs equipped with Tasmota firmware such as these. 4-pack for 36€ is an absolute steal.

They're wi-fi enabled, compatible with Alexa, Philips Hue, Home Assistant and sport an extremely powerful web interface & console. They're super reliable, the firmware is being actively worked on and overall just a brilliant alternative to much pricier and way more limited branded smart plugs.

ooh, neat!

Holy shit, I just realized they've finally turned on 5G in my area! My ADSL (20mbit) / 4G (~80mbit) multi-wan internet connection is about to skyrocket. I'm just gonna have to enable 5G on the secondary SIM card I have installed in my outdoor Mikrotik 4G modem/router, which btw I haven't had the need to reset or otherwise access in over a year. The very definition of set & forget, something I can't say for my ADSL modem.

Super curious to find out how fast it goes. I have a 5G phone, but I'm currently limited to 4G speeds / 150mbit per contract. I'm resigned to the fact that we're never getting fiber in this forsaken patch of land I'm on, so this is a very welcome development indeed.

Not looking forward to the cost of an external 5G router tho. Hopefully prices have come down a bit since I last checked. Mikrotik pls.

EDIT: They haven't, sigh.

EDIT 2: Son of a bitch, this morning we're back to the congested 4G+ network. I take it they're running tests or something.

EDIT 3: Nevermind, we back back!

It's only been a couple weeks, but I am liking TrueNAS Scale, so far. I still need to learn how to create my own TrueChart via K8/Kubernetes or whatever, but I think I have a handle on most every other feature that I am likely to use.

I knew Iphones were expensive but I was thinking the 13 would be available for $400 but the SE is more than that lol

My brother bought Samsung Galaxy Buds 2 Pro on ebay and got counterfeit ones, lol. He bought them as a gift, he already owns a pair, so it wasn't hard to compare and figure out.

I'm curious to see how it'll get resolved, if at all.

EDIT: Refunded, gets to keep the knockoff buds, which are actually rather decent.

My aunt bought an iPhone 15 and I managed to get her to download the move to iOS app and set her phone number up over the phone(took like 30 mins for her to find the imei).

But now she doesn't understand how to do anything. Does Apple have a video or manual? She said nothing came in the box besides the cable.

WHY DOES EVERY NEW HARDWARE STARTUP KEEP INSISTING ON MAKING WEIRD SHIT TO REPLACE PHONES? All of these new companies coming around are like "you know, people hate to use their touch screen phones, here's a dedicated voice assistant AI gadget that straps to your clavicle" -- PEOPLE DON'T HATE THEIR PHONES AND APPS. They're not craving a quirky gadget to replace the modern phone experience!

Also stop demoing AI that lets you easily book for travel, that shit will never be an easy 5 minute workflow. Booking for travel is a long and complicated experience because most of the time it's deeply personal and an exploratory type of thing.

It's all going great.

It was AdBlock's latest update at fault all along but man was everyone was quick to blame YT. I don't even know how YouTube would increase CPU usage to inflict bad performance on purpose. Whole story was nonsensical from the start but man did everyone buy it.
