simplifying expressions – Inactive and simplify does not work

Consider the following code:

Simplify[Conjugate[Inactive[cn][n, nAvg]], 
 Assumptions -> Inactive[cn][__] > 0]

If you run it, it will not simplify, i.e recognize that because Inactive[cn][n,nAvg] is supposed to be positive there is no need to put the conjugate. However, running this script returns:

Conjugate[Inactive[cn][n, nAvg]]
  • Why isn’t it working ?
  • How can I make it work ?

virtual machines – VM Instance is deleted after beeing inactive for some month?

Hello everyone and thank you for your help.

2 years ago i started a smal project on google platform and used the pre build WordPress from Bitnami.
Then i worked once in a while on the website. This time the payment and so the project was deaktivated for around 3-5 month. Now i wanted to aktivate it again, what i also did. But i cant find any old instance. The project it self is still there but the hole instance where all the data is safed doesnt apear to be anywhere.
Does google cloud delete instances after time automatically?
If yes, is there any way to get my WordPress data recovered?

Thank you a lot, i used a lot of time to create that side and it would be rly bad to do it all over again.

accessibility – Why is low contrast between active and inactive window title bars considered a good thing?

Microsoft gave some explanation for these changes to Visual Studio in this article:

Visual Studio 11 User Interface Updates Coming in RC (May 2012)

(emphasis mine)

Another area of requested change relating to user interface
controls/chrome has been for us to improve the overall sense of Metro
styling within the themes by drawing our own window chrome. By drawing
our own window chrome we have succeeded in both making more efficient
use of space and in increasing the overall sense of Metro styling.

the article continues…

The custom chrome and line work changes we’ve made together with
reducing the number of default toolbars and toolbar icons combine to
give you three extra visible lines of code in the editor compared to
Visual Studio 10
. As I noted at the beginning of the post the overall
objective behind many of the Visual Studio 11 theme changes is to give
you maximum real-estate for, and ability to focus on, your code.

It looks like Microsoft designed a custom title bar in Visual Studio 2012 to:

  1. Move the “Quick Launch” search bar all the way up to the top of the window, so that users could hide all toolbars and see a few extra lines of code.

  2. Make a more consistent metro theme.

  3. Increase focus on “content” (i.e., code)

Based on the article it seems like the custom, low contrast title bars were Microsoft’s attempt to “get you to focus more on your code” rather than looking at the window chrome.

Issues with Microsoft’s article:

  • If you hide all the toolbars, Visual Studio 2010 and 2013/2015 are very similar in the amount of vertical space you have for your code.

In the newer versions of visual studio, Microsoft made the tabs smaller, but they increased the size of the logo in the upper left, the notification button / indicator is also larger than a standard title bar button in Windows Classic.

For Classic Themes: Visual Studio 2013 and 2015 actually have one less pixel of vertical space than Visual Studio 2010.

VS2010 vs VS2013 code editor space comparison

For Aero Themes: Visual Studio 2013 and 2015 give you four additional pixels of vertical space. (Default font, the pink line is the top of the i in #include ... in Visual Studio 2010)

VS2010 vs VS2013 code editor space comparison (aero)

This comparison was done on Windows 7.

In Windows 10 / Visual Studio 2017:

  • Compared to Visual Studio 2010 with Windows 7 Aero, you gain an additional 3 pixels of vertical space for your code.

  • Compared to Visual Studio 2010 Windows 7 Classic you lose 5 pixels of vertical space.

So far no environment has more maximum possible space for code as Windows 7 Classic / Visual Studio 2010, though the difference is negligible (not even enough for a full line of code).

As for “Metro makes it easier to focus on content”:

A) In an article talking about Office 2007 (see below), Microsoft specifically mentioned that “Replacing the Window chrome is a very visible way to differentiate your app and increase branding impact”; it seems like if anything replacing the window chrome would make it so that users are noticing the unique look of your application more than the content.

With custom chrome, the application no longer blends in with the rest of the user’s system (and it will probably only look more foreign later on, because it doesn’t “evolve” when the OS updates).

B) Microsoft made the exact same claim about Windows Aero years ago (Archived: Oct. 2009):

One of Aero’s more visually obvious features is glass window borders, which let you focus on the contents of your open windows. Window behavior has also been redesigned, with subtle animations accompanying the minimizing, maximizing, and repositioning of windows to appear more smooth and effortless.

Office 2007

Joe Castro (Microsoft) wrote an article on the usage of custom window chrome (archived 2019), he mentioned Office 2007.

See excerpt below, he was mostly focusing on the technical side of it in the article, however, he mentions that replacing the window chrome can give your application a distinctive look, though it will require more work to implement standard system features. He specifically mentions Active/Inactive states as something requiring extra work.

It seems that some employees at Microsoft recognized the importance of differentiating between an active and inactive window, though perhaps a more “subtle” difference between active and inactive was preferred in the long run.

Predicting the future is hard – or “How to make some people unhappy,
all of the time”

Ultimately replacing the window chrome is doing the job of the window
manager. Emulating Windows like this has potential to miss behaviors
that your users expect, or not work correctly under some circumstances
(like high-DPI, or under a screen reader). Care should be taken to
ensure that the behaviors your users care about will work correctly
with your replacement.

For example, some of the standard window caption features today are:

  • Left-click on the icon to get the system menu.

  • Double click on the system icon to close the app (Office’s pearl does this as well).

  • Right click in the caption to get the system menu.

  • Double-click the caption to maximize the app.

  • With DWM, change the caption text style when maximized.

  • Change colors based on Active/Inactive states (The colors it uses respect DWM colorization when Aero glass is on, the Theme colors when
    not in Windows Classic, and System colors when in Windows Classic.)

  • It respects system metrics for sizes, and the metrics available for measurement have changed in different versions of Windows (e.g.
    iPaddedBorderWidth was added for Vista).

These are all things that the system no longer does automatically for
you when you use your own chrome. And some of this behavior has
changed in different versions of Windows.

Replacing the Window chrome is a very visible way to differentiate
your app and increase branding impact, but it’s likely that an
implementation will miss some things,
or that future versions of
Windows may change some behaviors making your app look out of place.

This doesn’t mean “don’t do this.” Just that replacing the chrome
should be an informed decision.

Also, user feedback on Office 2013 has shown that low contrast in title bars is not just a hypothetical issue:

And another thing, now that I have to have all of these separate window open, how can I tell which one is selected? Previous Office products had a color change in the bar at the top of the window to show whether that window had the focus. Office 2013 doesn’t seem to have any visible indication. I keep pasting things into the wrong windows.

macos – Why is “Find My Mac” still complaining about “Wake for network access” being inactive, although I just activated it?

  • MacBook Pro 15″ (Mid 2014)
  • macOS 11.2.1 Big Sur
  • Find My Mac gets activated for the first time on this device. There was no other user before ever, I bought it refurbed from, and I do not recall that I have ever used that function before, but now I wanted to activate it.

I did my initial setup of “Find My” on the Mac exactly as Set up Find My on your iPhone, iPad, iPod touch, or Mac (HT210400) describes, but in the process got a warning about “Wake for network access” being not active, although it was.

Exactly as HT210400 instructs. Numbers correspond to my screenshot series:

1 ) Preconditions: System Preferences > Security & Privacy:
“Enable Location Services” is ON, “Find My” is also ON. All fine.

2a) System Preferences > Apple ID > iCloud > Find My Mac is currently OFF. Toggle “Find My Mac” ON.

2b) In the dialog press “allow”.

2c) “Find my Mac” not shows as ON but has a warning symbol and a “Details…” button. Press that button.

2d) Dialog informs that you need “Wake on network access” being active. Press button “Open Energy Saver”. Btw an outdated label, the former prefpane “Energy Saver” in macOS Big Sur is meanwhile called “Battery”.

2e) I get redirected to the prefPane “Battery”. Activate “Wake for network access”. In my screenshot session I already did so earlier.

2f) Go back to prefPane “Apple ID” and “Find My Mac” still shows an error due to missing “Wake for network access”. Note: You can repeat cycle 2a-f as long as you want: The status icon is not refreshing properly as long as “System” is running!

3 ) In prefPane “Battery” I checked both sections “Battery” and “Power Adapter”. Option “Wake for network access” is only shown in section “Power Adapter” and there it is on.

Why is “Find My Mac” still complaining about “Wake for network access” missing, although it is activated?

4 ) Quit “System”. Restart it. Then go to: Apple ID > iCloud > “Find My Mac” now shows as ON and without any error symbol.









Is there a way to lock inactive screen on MobaXTerm?

Is there any setting or feature that makes MobaXTerm to lock the screen after some inactivity time and ask for a master password to unlock?

An inactive plugin causes an HTTP 404 issue on a translated post – WPML

I help manage, a bilingual food blog which runs WordPress (need I say that?) along with several other plugins including Yoast SEO and WPML.

Recently, I noticed 404 error reports in Google Analytics. I traced the beginning of these 404 error reports to plugin updates I ran on 12/8.

This blog post in English works fine but its French translation yields a 404. Yet the post is published and the slug is correct. I tried accessing the post with the page_id=xxx and it also 404ed. If I search for the post using WordPress’s search feature on the blog, I can see it, along with feature image, in the search results.

To narrow down the culprit, I made a copy of the site backup (before upgrade) to my staging environment and started updating each plugin one by one, testing whether a 404 occurred as a result. Eventually I narrowed down the issue to Yoast SEO Multilingual. This is the plugin that causes the 404.

You’d think it’d be the end of the story – roll back to the older version of the plugin and notify WPML, right? Well this is where things get weird: this plugin is actually inactive in both the prod site and the staging site (because I’d had issues with it many months ago). It’s been inactive and the site has been working fine. The inactive plugin has nothing to do with redirects.

So I’m pretty concerned at this point. Can a plugin install / update modify other plugins? Is there any kind of isolation to prevent that? Obviously, plugin installs / updates can modify the DB schema. So does this mean this plugin updated parts of the DB used by its sister WPML plugins?

I know this isn’t an ideal question. At this point, I’m looking for pointers. Thanks all!


  • Yoast SEO Multilingual is a plugin by WPML (in spite of its name).
  • Yoast does have redirects – it’s part of the Yoast plugin and those redirects work fine.

Does Yahoo still delete and recycle INACTIVE email accounts?

In 2013, Yahoo had announced that it will delete inactive accounts and free them up to give them to new users (recycle account IDs). Users could apply for the ID they wanted and about a month later they would know if they got it or not. I think there was a fee for that? I don’t remember that.

Is this policy still enforced? Are inactive accounts deleted and recycled? I attempted to find but 2013 was the only year that was mentioned everywhere and the language suggested that it was a “one-time” thing.

Edit: This page really confuses me. They say it is not possible to reuse permanently deleted IDs but everywhere else (including on this site) I find that in 2013 at least, they made it available for reuse?
