slipstream-··on US telcos appear to be selling non-anonymized access to consumer telephone data
You misunderstood: the commenter said they'd provide a passworded wifi network and a sign somewhere saying "visit this URL to get the password for the wifi!"

People would visit that URL using mobile internet...

slipstream-··on Ask HN: Why doesn't Microsoft build its own Android “fork”?
I also heard "too well", as in, developers just wanted to use their android apps instead of making windows apps.

It wasn't totally canned though, it became the Windows Subsystem for Linux.

So, scratchcards then?

slipstream-··on Build command line apps using PHP 7
I've written small command line scripts in PHP before (without any helper libraries). Using PHP for such things is nice when interfacing with web services (JSON parsing, SimpleXML, etc).

Perhaps Peachpie, when it reaches production quality, will also help with that, as then calling .NET (and maybe, through that, WinRT) APIs from PHP code will be made easier.

What do you expect, from an entity that advertises via spreading malware/PUPs?

ARM64, not ARMv7.

Also, from what I hear, binaries need to be compiled specifically for this - others just use a slower JIT emulator.

slipstream-··on The Minifree Libreboot T400 is free as in freedom
I tend to buy from a UK vendor who I found out about through favourable magazine reviews. The last few times I ordered from them, they offered no-OS options (which in practise meant a preinstalled but non-activated Windows, and Windows reinstallation media provided).

Unfortunately, malware has shifted back into breaking systems, under the form of ransomware.

If you sideload it as an unpacked appx in developer mode rather than an unpacked extension it doesn't do this.

I agree. Malware has been known to install vulnerable signed drivers to get unsigned kernelmode code execution.

>On the other hand, Microsoft could have easily gotten a much more "robust" lockdown - by simply demanding mandatory, unchangeable Secure Boot like on the ARM tablets. But they didn't do that.

Didn't you hear that Secure Boot is basically broken?

slipstream-··on Why the Apple II ProDOS 2.4 Release Is the OS News of the Year
7.1 wasn't just a version number that China DOS Union made up but is the actual version number of win98's (and 95 OSR 2's) DOS.
slipstream-··on How to get people who installed a leaked build to stop using that build?
So, default wallpapers in early Windows 95 builds.

The first Preliminary Development Kit had an "Under Construction" wallpaper. The second one had the same wallpaper but tiled. Beta 1 had a different "Under Construction" wallpaper.

Of course, after PDK1 leaked far and wide, MS implemented some serial protection in PDK2 up to beta 2 (different from the one in the RTM; however the RTM's setup has remnants of it). Given that the leakers were involved with the warez scene, however, the skilled reversers that the builds were passed to easily found the backdoor that had been put in so that those on MS' internal network didn't have to enter the serial, and just patched a few bytes in the setup to abuse that.

The interesting part of this serial was that it was in two parts. One part was the "beta site ID" and half of the "password"; if this was valid, but the second half of the password wasn't, setup would appear to continue... until the point it would copy files, upon which it errored out with a message "General error 57, please contact your beta administrator".

This misdirection was discussed at the time, with some people believing the error at face value. This continued with the foundation of communities to preserve and discuss such builds several years onwards. The last half of the password was the hex form of the first 16 bits of an MD4 hash (this code was written in around autumn 1993!) of the beta site ID, the first half of the password, and... a string inside the setup that was used as the titlebar text for the error message, which would be something like "Microsoft Chicago Preliminary Development Kit 2, November 1993".

This part of the serial algorithm was finally reverse engineered, and a key generator made....in 2014.

Afterwards, some early Internet Explorer 4.0 builds were discovered. They used the exact same serial algorithm as the early Windows 95 builds. And had the exact same "MS internal" backdoor.

(Um, I think I may have just ruined one of Raymond Chen's future blog posts.)

"help track down leaked builds of Windows"

If you're talking about public leaks (rather than just private leaks to a few individuals), surely they're not that hard to find?

I wonder if you mean the leakers?

(for the record, I'm a moderator of a forum which discusses said "leaked builds of Windows"; and I help try to find and preserve those that leaked long enough ago such that they have almost disappeared)

MS' own advisory says you don't need physical access (only admin rights).

Yay for Let's Encrypt.

slipstream-··on Secure Golden Key Boot
No, it doesn't. It merely prevents the use of one way to install some policies on Windows RT devices.

On Phone, the exploit chain to do exactly that is already public.

Maybe so; but I didn't want to implement too many effects. :)
