Power usage is also very reasonable! 400GE switches and routers pull a ridiculous amount of power.

"there was a correction issue" is downplaying it. Etcd is truly the worst example of Raft. Etcd corruption and loss of quorum is extremely common in practice and the GitHub issues sit for years. The design is simple, the performan

I don't think iPhone Upgrade Program was ever the best deal to be honest. It's just convenient.

I stand corrected! This doesn't look too bad then.

The Apple Upgrade lease model isn't even a replacement as you have to wait 24 months before upgrading. The entire point of the iPhone Upgrade Program was to make it painless to swap to the newest iPhone every year. Without that, there&

You'd be surprised to know that this strategy works quite well! Pixel bots require a hardware fake display when faced with kernel anti-cheat. They also depend on color/pattern recognition, as AI is not yet capable of operating at

Aimbot is actually very solvable! 1) When DMA is fully blocked, Aimbot resorts to being a pixel bot. 2) Once you're relying on a pixel bot, all the anti-cheat has to do is "bait" the bot. After you click the bait a few times,

I feel someone doesn't need to play competitive games to be able to give an honest assessment of the privacy & security risks. I'm sad I'm not seeing that honesty elsewhere in this thread.

At least in Valorant, DMA is becoming impossible due to IOMMU / Memory Integrity enforcement. The only option is becoming pixel bots. As for faking the input device: I'm sure it's possible, but I'm also sure that perfect

In my opinion, the debate about kernel anti-cheat on Windows is disingenuous fear-mongering. I'm confused why Hacker News of all places misrepresents the technical details. You can already completely compromise the average user's

That's a different type of game entirely. Private/community servers cannot be competitive at the scale of modern competitive games.

This isn't possible in Valorant. Their kernel module is extremely particular about input devices: 1) only allows a single mouse input device at a time 2) completely ignores virtual mouse input 3) flags "special"/"un

I don't disagree. Clarifying, I personally don't think this exploit is a backdoor, but rather that the negligence is enough to appear malicious. Just for fun (not saying I believe this!): Did you ever consider that a malicious Mic

If the device doesn't have BitLocker, this exploit is pointless because you can already boot any OS USB and immediately have full access to the unencrypted disk. This exploit is only ever relevant with BitLocker enabled (as a method to

1) Except that the entire premise behind BitLocker TPM's security relies on the login screen as a hard security boundary, and thus any attack on the login screen is an attack on BitLocker. It is semantics to dispute this and certainly

That’s quite a stretch, to say the least.

But it doesn't. Full authentication bypass exploits are extremely rare and unheard of among tech giants. Maybe account takeover/recovery, sure, but full bypass? It just never happens. Microsoft goes beyond that: they've manag

I knew there was another incident that I was forgetting, insanity... I don't understand how Microsoft keeps getting away with this and everyone just forgets.

Microsoft has never been good at security, and that is why their centralization to cloud is absolutely terrifying. I'm reminded of Storm-0558 [1] where a stolen signing key was able to forge authentication tokens for any MSA / A

I'd use WireGuard in that case. The main reason WireGuard is popular at all is because it is approachable. IPsec is much more complicated and is designed for network engineers, not users.

That's a large packet benchmark, not mixed packet size, and it just barely hits it. If you need consistent 10Gbps for a business use case, I would not consider that sufficient. > "To me, the bulk of Tailscale's overhead

Mikrotik can be popular for CE (Customer Edge) devices, that is correct. Those are not ISPs however, those are customers.

by iscoelho 8mo ago
CE (Customer Edge) is what you are referring to. ISPs would be the PE (Provider Edge). I am aware it can be popular for SMB CE devices, however that is simply not the case for PE devices. Service Provider ISPs cannot use Mikrotik - It is im

AWS/GCE/Azure's network implementations pre-date EVPN and are proprietary to their cloud. EVPN is for on-premise. You don't exactly have the opportunity to use their implementation unless you are on their cloud, so I am

I'm curious what you classify as a business ISP? Take a look at AMS-IX, one of the largest internet exchanges: https://bgp.tools/ixp/AMS-IX 21/1020 (2%) of all peers are Mikrotik. 15 (1.4%) of those are >=
