What makes you say that they don't? The math behind cryptography doesn't care if it's hardware or software. a lot of hardware relies on obscurity instead of cryptography (unsigned firmware updates, relying on not labeling pins to keep people out of powerful debugging interfaces, etc.). the math beh...

Well, there's also the matter of whether they're running a 64-bit capable OS - I've even seen vendors shipping 32-bit Win10 on 64-bit capable hardware. Not sure why they'd do that, unless licenses cost more for one than for the other...? But it is a thing. 32-bit Windows 10 does officially require ...

apparently it could store "over 1000 recipes". can a binder do that?

Not in that they used it for that long. More that the same "computer" they used as an advanced version of a recipe book was also primary 'computer' monitoring the temperature of the reactor. it probably worked a lot better for temperature monitoring than for storing recipes with only togg...

That's a "recommended hardware configuration". It doesn't really mean anything. It can't possibly take 512 MB of RAM to install Firefox when Firefox itself is 200 MB large. It takes 512 MB of RAM to install Windows 7, which are 16 GB large. Try it in a virtual machine, I distinctly rememb...

I am quite sure Firefox 43 (the latest version which can be easily installed on Windows XP) can be installed (not just run once it's installed) on a virtual machine with around 150MB of RAM running Windows XP. nope: https://www.mozilla.org/en-US/firefox/43.0/system-requirements/ also: https://en.wi...

Under Windows XP, both Firefox and Notepad++ run without problems on a virtual machine with around 150 MB of RAM. What more do you need? https://www.mozilla.org/en-US/firefox/58.0.2/system-requirements/ 512MB of RAM / 2GB of RAM for the 64-bit version that's quite a bit more than 150 MB just for fi...

What are you talking about? Windows XP and Windows 7 need 64 MB and 512 MB of RAM only to install. Once they are installed, they require less than half of those amounts to boot. Have you tried them in a virtual machine? Windows XP, once it's installed, can boot with 25MB or RAM in normal mode, and ...

Can you link to an example? (Of a "new feature" that's really a security update) how about their failure to add support for any reasonably secure (ECDHE and AEAD) TLS cipher suites to windows vista? How come Windows XP can run on 64MB of RAM, while Windows 7 barely run on 512MB of RAM? XP...

I also don't think it's fair to say that Win 7 isn't usable any more. Even if you took a liberal definition of "unusable" to include that it's not safe to use because it doesn't get security updates, there's still almost two years left of usability. only if you're paying microsoft for a s...

I have this idea of making two identical antennas connected by coaxial cable and placing one of them outside and the other inside the wall. A little update on this idea: I tested it today and got no signs of it working as I thought it would. This is probably because I didn't pay too much attention ...

hotaru

Mess with the internal antenna connection hiding under the backplate, which seems to be more durable and using a standrdised connector. It's rather small and probably not designed for a large number of connections either, but if I can get the matching connector I can test my antennas more thoroughl...

There's one more case that's even sneakier. Worry no more about transitivity. You can solve this: var a = ...; var b = ...; if (a == b && a != b) console.log("seriously?"); var a = 0; var b = {v: 0, valueOf: function(){return this.v++}};

Maybe we just disagree on what "significant" means, but I think that qualifies. 22% over 6 years is not a significant increase. especially when you consider the fact that there has been no difference in IPC between the last 3 generations (skylake, kaby lake, and coffee lake), and you can ...

I'll add to this that while single-threaded performance hasn't scaled like it did in the 70s and 80s, there's still been fairly-significant improvement in the last 10 years from my understanding. it really hasn't. Intel hasn't made any significant improvements in IPC since sandy bridge (2011), and ...

From bitter experience, I know that running defrag from DOS 6.22 (or earlier) on LFN-supporting FAT areas like a Win95 (or later) does a brilliant job of reducing trivial and inconsequential directory names such as "Program Files" to the handier "PROGRA~1", and likely a whole se...
