Not related to this comic in particular, but the advertisements on this site have become a little (well, actually well past that) too obtrusive for use on a computer that won't let you install an ad blocker (like, uh, a managed Chromebook). Oh, imagine trying to use a computer that won't let you install something as necessary in 2019 as an ad blocker in 2019.

Really? For me it's only a tiny rectangular ad in the bottom left when I disable my blocker. [[Special:Contributions/172.69.34.20|172.69.34.20]] 01:53, 5 November 2019 (UTC)<br />

I bet that this is in reference to the removal of close other tabs from Chrome. [[Special:Contributions/173.245.54.37|173.245.54.37]] 03:23, 5 November 2019 (UTC)<br />

: I doubt it. The feature is easily duplicated by simply tearing out the tab you want to keep and then closing the other window. I doubt that would be a dealbreaker. Plus, well, Chrome doesn't play nice with trying to stay on the older version. [[User:Trlkly|Trlkly]] ([[User talk:Trlkly|talk]]) 03:29, 5 November 2019 (UTC)<br />

It's not so clear to me that SaaS requires the software to run in the Cloud. Adobe's Creative Cloud is argued to be Software as a Service, but the programs actually run on the local system. [[User:Trlkly|Trlkly]] ([[User talk:Trlkly|talk]]) 03:29, 5 November 2019 (UTC)<br />
<br />
The definition in the Wikipedia article on SaaS includes that requirement. I would describe Adobe Creative Cloud more like the way its Wikipedia article does, as providing a combination of software applications delivered on a subscription model, mobile apps, and cloud services, with only the latter being the SaaS part.

:Yes, Photoshop is installed on my machine, and I can run it when I'm not connected to the Internet. Definitely not SaaS. SaaS doesn't have to be from the cloud, but it must be something served when you use it. — [[User:Kazvorpal|Kazvorpal]] ([[User talk:Kazvorpal|talk]]) 06:20, 5 November 2019 (UTC)<br />

I think the explanation is probably misinterpreting the intent of the title text. Given the point of the main comic, rather than saying some have very fast ping times, I think it's saying they may have very slow ping time, on the order of months or years, between times when they decide to download an updated version. The explanation written here definitely feels off, as lots of software running doesn't involve even a local office server, but runs entirely on the computer in front of the user, and again it doesn't relate to the main comic.--[[Special:Contributions/108.162.216.46|108.162.216.46]] 06:58, 5 November 2019 (UTC)<br />
:I was going to say the same. Cloud software will include some frontend code to display data to the user; often some javascript in a webpage. I think the title text is treating 'regular' software as if the developers and their computers creating updates are the part which runs "in the cloud". In some cases, this might mean actually sending off for disks for an update (a 'ping time' in weeks), and the timeout before disconnection causes an error could be years or longer.

:: The part about a "server in the same office" should just be removed. Software ''on your own computer'' is also running in the cloud - there's no fundamental difference between software running locally or remotely except for the connectivity issues (latency and packet loss etc.) in transferring the data. Your own computer is a "cloud server" with extremely fast (sub-millisecond) ping, whereas accessing a server on another continent may cause latency of a few hundred milliseconds (or more, if packet loss is bad enough) and this is what the "ping times vary a lot" line is referring to. I don't think it's referring to software updates. -- [[User:Pureawes0me|Pureawes0me]] ([[User talk:Pureawes0me|talk]]) 09:45, 5 November 2019 (UTC)<br />

Oh, hey, that looks like my Android version (because Google apparently thinks no one would want to record their own calls).

The cosmologist is probably using Fermi's a la [https://what-if.xkcd.com/84/ What-If 84: Paint the Earth][[User:OhFFS|OhFFS]] ([[User talk:OhFFS|talk]]) 20:34, 20 September 2019 (UTC)<br />
: In that What-If, the rounding formula for Fermi problem estimation is given as "Fermi(x) = round10(log10(x))". [https://www.google.com/search?&q=log10%28pi%29 log10(pi)] (Google search, shows calculator) is roughly .4971... so close enough that someone could do a "Fermi rounding" to either 1 or 10 and not really care one way or another.

As a physics Phd (though not working in astrophysics), approximating pi to 1 is not all that bad. Especially when the measurable quantities that go into the calculation usually have huge error bars.--[[Special:Contributions/172.68.59.120|172.68.59.120]] 21:03, 20 September 2019 (UTC)<br />
<br />
Using natural units (setting c=hbar=1) is different from setting pi to 1. Using different units is always allowed and not an approximation. Setting pi to 1 on the other hand, is an approximation and is only justifiable if the other quantities in the calculation have huge uncertainty. --[[Special:Contributions/172.68.59.120|172.68.59.120]] 21:07, 20 September 2019 (UTC)</div>162.158.142.118
