sgjohnson··on Electron-based apps cause system-wide lag on macOS 26 Tahoe
You can still find applications written for Windows 3.1 in the latest builds of Windows 11. Something regarding database drivers if I recall correctly.

Now imagine if you could get rid of all that legacy crap to make it work in the first place. Microsoft CAN’T do that, because the entire premise of Windows is backwards compatability.

Apple? They don’t care. Killing 32bit apps? Just make an announcement saying that in 2 major macOS releases, macOS won’t be able to run 32 bit apps. It cuts down bloat, and it cuts down on the potential attack surfaces for malicious actors.

Obviously just about everyone would agree that Windows 1 -> 7 was progress. I don’t think you’ll find too many people who’ll say the same about Windows 7 -> 11.

sgjohnson··on The EU Just Killed ARR
Just adopt the JetBrains model? Each consecutive year of uninterrupted subscription gets you a discount, up to a point.
sgjohnson··on Windows 10 resists its end: usage share climbs while Windows 11's falls
> while their products plateau with little innovation to show

Seen the battery life figures on yesterday’s iPhones? And ARM revolution was just 5 years ago.

I would hardly call it “little innovation to show”.

sgjohnson··on Windows 10 resists its end: usage share climbs while Windows 11's falls
> Assuming Apple itself doesn't bypass Little Snitch, I don't even think Apple is doing the level of telemetry Microsoft does.

Apple doesn’t do all that much telemetry even if all the telemetry settings are enabled. Because you’re not a product to them. Which is probably why they didn’t even play in the AI race.

sgjohnson··on Windows 10 resists its end: usage share climbs while Windows 11's falls
Windows 11 is probably the reason why Apple are going to launch a low-cost MacBook. Not that $999 isn’t already cheap, but if they release a $699 version...
sgjohnson··on Do the simplest thing that could possibly work
The title is not “Do the simplest thing POSSIBLE”. It’s do the “Simplest thing that could POSSIBLY work”.

There’s a HUGE difference between the simplest thing possible, and the simplest thing that could possibly work.

The simplest thing that could possibly work conveniently lets you forget about the scale. The simplest thing possible does not.

sgjohnson··on The Chrome VRP Panel has decided to award $250k for this report
> How is being able to put a down paymenent on a house or being able to send your kids to collage debt-free not life changing?

Because neither of those are going to change your daily life that much? It simplifies a thing or two, but neither of those things are life-changing.

sgjohnson··on The Chrome VRP Panel has decided to award $250k for this report
Depends on where in the world you are. I wouldn't call $250k life-changing-money anywhere developed.

It's "I can probably stop worrying about money for a while" kind of money, not "life-changing" money. Not a whole lot you can buy for $250k. After taxes, that probably doesn't even buy a house.

sgjohnson··on Welcome to the IPv4 Games
bool IsPrivateIp(uint32_t x) {

  return (x >> 24) == 10                   /* 10.0.0.0/8  */

         || (x & 0xfff00000) == 0xac100000 /* 172.16.0.0/12  */

         || (x & 0xffff0000) == 0xc0a80000 /* 192.168.0.0/16  */;
}

the code doesn't consider 127.0.0.0/8 as "private". I'm curious about 10.0.0.0/8 though.*

sgjohnson··on Welcome to the IPv4 Games
_nobody_ would waste a botnet of 9 million unique IPs like this.
sgjohnson··on Welcome to the IPv4 Games
can't spoof the source IP in TCP communication, as the handshake cannot happen.

With UDP you can send whatever, but obviously you won't be able to receive the response.

sgjohnson··on Ubiquiti launches UniFi OS Server for self-hosting
Multi-site centralized management if you don't want to use Ubiquiti's cloud. UI has an entire lineup of non-Cloud gateways.

This is also for setups without an Ubiquiti gateway. Like a setup with just UI switches or APs.

sgjohnson··on Ubiquiti launches UniFi OS Server for self-hosting
Nothing in the Ubiquiti ecosystem requires you to use the cloud. Even fully air-gapped setups are supported.
sgjohnson··on Intel CEO Letter to Employees
That article is nonsense, even if it's up to the implementation, not ISA.

Apple's M4 Max owns AMDs top consumer CPU (Ryzen 9 9900X3D) in both, single and multi-core workloads, while consuming a fraction of power that the AMD chip does.

The year-on-year performance improvements on Apple's ARM chips are just insane. If it really was so simple, then why haven't Intel and AMD pulled their heads out of their asses in the last 5 years and re-designed their cores from the ground up?

sgjohnson··on BGP.Tools: Browse the Internet Ecosystem
No. It will take 10 years for everyone to update their router configuration/software to treat the new “formely-reserved” addresses as global unicast. There’s no point in doing that whatsoever. That effort would be spent much better by adopting IPv6.
sgjohnson··on Intel CEO Letter to Employees
x86 is the WORST modern architecture if performance-per-watt is considered. And extra power consumption means extra heat.

The only reason why I even still have an x86 PC is to play videogames. For all other purposes I’ve got ARM machines.

sgjohnson··on Air Force unit suspends use of Sig Sauer pistol after shooting death of airman
FWIW I love the 1911-style grip safety. It’s a shame that more guns don’t have that.
sgjohnson··on Linux and Secure Boot certificate expiration
Secure Boot does nothing whatsoever to prevent that. Disk Encryption has got nothing to do with Secure Boot.

what do you mean?

there are many ways to intercept inter-LAN traffic, and:

DNS validation? Run your own CA and trust it in your intranet?

sgjohnson··on Getting ready to issue IP address certificates
Shame that IP address certificates can’t be done via the DNS challenge, but I completely understand why.
sgjohnson··on How malicious AI swarms can threaten democracy
Doesn’t matter. Our species survived. Individual casualties don’t matter in the grand scheme of things.

We survived industrial revolution, we’ll survive AI.
sgjohnson··on Pentagon Has Been Pushing Americans to Believe in UFOs for Decades, New Report
> Meanwhile this site disappears a 1500 comment thread about the Marines being used to crush incredibly peaceful resistance to the unconstitutional regime's White Supremacy. US citizens are being violently kidnapped, and for what?

That topic is not intellectually interesting. I don’t really come here for politics, and I’d like to believe that neither do most HN readers.

sgjohnson··on Bruteforcing the phone number of any Google user
Absolutely nothing whatsoever.

If SIM Swap doesn’t work, you can always attack SS7. There’s also nothing you can do about that.

So stop using your phone number as an authentication factor. It’s trivial to pwn for any actor determined-enough.

sgjohnson··on The Rise of 'Vibe Hacking' Is the Next AI Nightmare
Good luck shutting down the LLM running on my MacBook.

The Pandora’s Box is open. It’s over.

sgjohnson··on Root shell on a credit card terminal
I guess for a restaurant it basically always makes sense to accept offline payments. I wasn’t aware that they might not be able to process card payments when I ordered.

I don’t typically carry any cash on me, and, well, if their terminals go down before I’ve closed my tab, they assume all of the risk anyway.

sgjohnson··on Root shell on a credit card terminal
Maybe today, when the line between a Credit and a Debit card has gotten significantly blurrier (except in the US).

I definitely remember making an _offline_ payment with an AMEX card at a restaurant in the UK some 10 years ago.

Also, most airlines that take payments on board also run the terminals in offline mode.

There must be some mapping of BIN codes and whether to allow an offline transaction.

Eh, I’m the exact opposite. I don’t want to spend a single day as a vegetable.

Is it though? You either succeed, or nothing is ever your problem again.
