@nalinrajput23 People stopped carrying devices that just play music....

@blind_via I feel like audio add-in cards haven't been necessary for consumers since Intel HD Audio. Although there might have been some value for gaming, the need for a dedicated audio hardware DSP has long since disappeared.

@vaxryy It was the best of times, it was the worst of times. It was the age of templates, it was the age of fuckery.

The 1GHz processor req. has been there since Windows Vista*. They don't bother updating it yet in reality you can't run Windows 11 unless your CPU supports the POPCNT instruction, which means Intel Coffee Lake or AMD Zen+.
It would be interesting to get a 1GHz 2017-era CPU and downclock it to 1GHz to see how it actually fares though...

@air_intel Concorde is a perfect example of European innovation. It cost the tax payers a fortune, only benefitted the elite class, massively over ran, out of date before it launched.
In the end it was sold to commercial airlines for £1 but only the superrich could afford to fly on it.

When Britain goes with France instead of America we build cool shit

I've got a very bad feeling that dumping America for France is not going to serve us well. This is a mistake, we're making a very big mistake.

@FranklinH3000 I distinctly remember the day he was freed from prison. Never understood the modern myth.

@Truthcoin You shouldn't synchronize to some auth server. Synchronize to a known good time source. If the phone has a GPS device this is a good candidate.
I don't know why this isn't enabled by default by you can do it if the device is on Android: @python-javascript-php-html-css/using-gnss-time-to-sync-your-android-clock-for-precise-log-integration-b9a9d0ca62cf" target="_blank" rel="nofollow noopener">medium.com/@python-javasc…

Did you know:
Google Authenticator **requires** that your phone clock match the server clock.
Given that, you would think:
1. There'd be a little button in the Authenticator app, to show you your current time -- and let you set/modify it if needed
2. The server (asking you for 6-digit auth), would also tell you what time *it* thinks it is, so you can synchronize them
Instead, none of this is explained.
I have some air gapped phones, where the clock has drifted, all by itself
And sometimes, in the past, due to switching timezones, manually setting and resetting the clock has caused it to drift away from UTC time

I'm going to assume you have an OEM device and rather than use their recovery software you have installed retail Win 11 Home. It installed in S mode probably due to the license in the BIOS.
One option would be to use a network device that has good Windows support. For example, a cheap USB ethernet, WiFi dongle or docking station.
The other option is to unpack the drivers on a working PC and install them on the target machine in Audit mode. Depending the driver this might require Manufacturing mode, in which case consult the documentation for further details.

@Jonathan_Blow Fine, just ignore the email from wobblycockmonster@gmail.com then!

There are many requests to get into the compiler beta. And sometimes I am very busy, so it's a while before I add new people (this time, it's been 5 weeks).
Just as a public service announcement though, on a day like today, if you mailed to get into the beta and your name is like "Thunder" or "vampire master", your chances of getting in are substantially decreased.
Thank you for your attention to this matter.

@Rothmus Do people not understand that the detective who "found" the glove in this case perjured himself on the witness stand. The defence exposed him in a lie via audio tape evidence and he was later convicted of perjury.
That and don't get me started on the blood sample fiasco.

@straceX This is true but INT_MAX has been in the standard since, well since the ANSI standard.
Isn't the problem that we aren't teaching people how to write correct C ?!
English

This isn't how TLS works at all! 😑
TLS encrypts the entire session, including all headers. Server Name Indication was added to TLS to allow the hostname to be exposed in the (unencrypted) handshake but all the HTTP headers are encrypted.
Every connection between a client and web server is encrypted with a different session key. If a client receives an encrypted response that was destined for a different client, it won't be able to decrypt it as it has the wrong session key.
Key exchange is performed in such a way as to authenticate the server certificate as genuinely issued by a known certificate authority. If a third-party tries to swap keys around or forge keys, the authentication step will fail.
CDNs work by either uploading static files directly to their servers (not sure if that's still a thing) or terminating TLS at the CDN then reverse proxying to the destination server.
English

CDNs cache the encrypted response, not the plaintext. The HTTPS encryption happens at the TLS layer between your client and the CDN edge. The CDN sees the full encrypted blob, caches it exactly, and serves it to other clients who also get encrypted responses. The HTTP cache headers (Cache-Control, ETag, etc) still work because they are part of the encrypted envelope. This is how CDNs can cache HTTPS content without ever seeing what is inside.

@DrSynod @reddit_lies @donerkebab7 @davidbombal @ThreatLocker Ugh, no that's not what I was saying at all. This entire thread is about convection cooling. Thanks, bye!
English

@djonesuk @reddit_lies @donerkebab7 @davidbombal @ThreatLocker I replied to a post where you described conduction cooling (literally used the word “contact”) and misattributed it to Stefan-Boltzmann, which has nothing to do with conduction or convection, but instead is based on radiation, where you don’t need contact.
English

Why space servers FAIL
Execs want to put data centers in space, but there's a massive physics problem: vacuums have no convection cooling. Discover why cooling servers in space relies purely on infrared radiation!
Big thanks to @ThreatLocker for sponsoring my trip to ZTW26 and also for sponsoring this video. To start your free trial with ThreatLocker please use the following link: threatlocker.com/davidbombal
English

That's what the video is saying. You have to rely on radiative heat transfer to get rid of excess heat.
Taking the ISS as an example, it has 4 pairs of radiators. Each pair can dissipate 14kW of heat energy.
Depending on configuration, 14kW represents the heat produced by approx. one full rack of server equipment. You can optimize for less heat by reducing clock speeds whereas adding GPU compute would push that number up. Let's assume arguendo that one rack produces 10kW heat.
So if you took all the people and equipment off the ISS it could support about 6 full racks of compute servers. That's not a datacentre, it's a computer room.
It's not impossible, but it's difficult to see the economics of it stacking up any time soon. Add to that the current trends in computing are towards edge (i.e. closer to the user not further away) and I much prefer Microsoft "under the sea" approach.
English

@donerkebab7 @djonesuk @reddit_lies @davidbombal @ThreatLocker yeah basically you end up having to only radiate away on the side in shadow, and then the sun facing side you'd put very reflective material. so half the area, but still not impossible
English

@DrSynod @reddit_lies @donerkebab7 @davidbombal @ThreatLocker Not sure why you felt the need to post that in a thread that begins "vacuums have no convection cooling" but okay!
English

@djonesuk @reddit_lies @donerkebab7 @davidbombal @ThreatLocker Stefan-Boltzman describes electromagnetic radiation of photons as a means of dissipating heat, not conduction by transferring heat to nearby matter.
You do not need stuff in contact with a satellite for it to radiate heat as it can be radiated via photons.

Petit rappel pour les ignares du fromage, il existe 4 principaux types de "croûtes":
- cire : non comestible, c'est de la cire, comme pour les bougies. Ex: Gouda
- fleurie : c'est du champi pulvérisé sur le fromage (penicillium), blache et douce, comestible. Ex: Brie

@reddit_lies @donerkebab7 @davidbombal @ThreatLocker Ambient is the temperature of the stuff that's jn contact with the surface. The problem with space is that is empty!
English

@donerkebab7 @davidbombal @ThreatLocker If you emit to deep space, T_ambient is like 2 kelvin. His analogy with an air condition unit assumes a T_ambient is nearly the same as T_surface, so there's basically thermal radiation at all in comparison.
