android – Why is screen HEIGHT not taken into consideration while designing responsive layouts for mobile apps?


When we’re talking about the interfaces, we’re obliged to take into account the devices that makes us possible to display the content we aim to see. So that the main medium when the term responsivity was introduced was computer screens/displays and web through computers.

As you might imagine displays of all the computers/notebooks, the screens are rectangular on default and people using these displays intend to make browsers/applications minimized via reducing it’s width rather than the height as it opens more broader and wider area.


Doesn’t responsive layout mean that my app should look the same in devices of all widths and heights?

Well, it’s just because in these days mostly people are mobile users and the term need to be updated as the term responsivity originally also covers the same issue. Or there might be attempts to describe the concept differentially as only mobile users ran into this seperation since web is mostly on rectangular screens.

If 2 devices have a lot of difference in HEIGHT, my app in one device
will look drastically different from the one in other device

Besides you’re totally correct and even it’s the same for width for development point of view, it might mostly happening beacuse the heights are used %100 to fit all the screen sizes for mobile preferably. But that’s not my main arguement and point to avoid using responsivity as a height on mobile or web eventually.

security certificate – Sharing of CNN-based applications (in consideration of EU Medical Device Regulation)

Dear Webmasters team,

I work in a specific biomedical subdomain and would like to make CNN applications (PyTorch or TensorFlow-based models) accessible to physicians.

Essentially, image data would need to be uploaded (ideally via drag and drop), processed and a prediction would need to be returned to the physician. Apart from limited information at, it is really difficult to get much information at all on how to do so practically, while being on the “safe side”.

Core question:
Is there any all-around resource/tutorial that explains in a simple manner how to make a CNN accessible, while ensuring maximum data security (i.e., hosting options, secure upload interface for patient data, secure return of the model output)?

Best regards and thank you,

web – Is Cumulative Layout Shift a consideration while the page is still visibly loading?

As pointed out by musefan in his comment, CLS is problematic, even if the page is under a dark overlay, because the user may start to read the content.

musefan suggests “keeping all the content hidden until it’s ready”. This is the best approach, however, care should be taken in order not to create the impression that the page loads slowly.

It is a known issue that reducing CLS while following modern performance best practices can be tricky.

According to Cumulative Layout Shift in Practice (blog article),

Websites that are tuning for performance may be exposing themselves to more layout shifts unintentionally. Besides lazy loading, fast-loading sites optimize for a quick first paint, to get something on screen for the visitor’s eyes. As additional content comes in, it may be shifting the page around significantly.

One way to fix CLS without affecting performance would be to display only a loading screen, or spinner, or some kind of placeholder to the user, until all the page content is fully loaded. Another approach is using skeleton loading pages, which galenrutledge describes in his answer.

web – Is Cumulative Layout Shift a consideration while the page is still loading?

Cumulative Layout Shift (CLS) refers to unexpected change in the position of content on a page, and usually happens because resources are loaded asynchronously or DOM elements get added to the page above existing content.

CLS can be problematic if it occurs in the instant a user wants to interact with an element on the screen, which might cause them to click or press something else.

But is CLS relevant during page load? In the time before the page becomes interactive, can a shift in the page’s layout lead to a bad UX?

I am referring to the case where the user will see a spinner as well as potentially a dark overlay over the page, so they are unlikely to be trying to interact with the page. While the problem described above may not happen, I am wondering if CLS may still cause confusion due to elements momentarily being rendered in a location which is not their final location.

linear algebra – Trace inequality under consideration of definiteness

Let $G in mathbb{R}^{3×3}$ a symmetric, but indefinite matrix and $U in mathbb{R}^{3×3}$ a symmetric and positive definite matrix. Now, the following inequality shall be proved:
$$ text{Tr}(G^2) leq text{Tr}(GUGU^{-1}) $$
If $U$ and $G$ have the same eigenvectors, both sides of the inequality are obviously equal. However for more general cases,
I have tried to rearrange the inequality to
$$ text{Tr}(underbrace{(UG-GU)}_{text{skew-symmetric}} GU^{-1}) leq 0 $$
and then using the Cauchy-Schwarz inequality in order to achieve an upper boundary that possibly fulfils the inequality. Unfortunately, I have not found a solution yet.

Thanks for any advice!

starfinder – Can a Solarian’s ability to enter a Stellar Mode take into consideration conditions affecting her?

Here’s the full text:

When you’re not in combat, you can’t enter a stellar mode. This ability manifests only in high-stakes situations, when your training takes over and connects your mind to the universe. There needs to be some risk to you for your stellar mode to activate, so you must be facing a significant enemy. If there’s any doubt about whether you’re in combat or able to access your stellar mode, the GM decides. This also means that your stellar mode might end before what was previously a dangerous battle is over, once all that remains are dregs that don’t pose a real threat to you.


In general, a creature with a CR less than or equal to your character level – 4 is not a significant enemy.

Your quote contained most of that sentence but omitted the text “in general”.

If a character is paralyzed, then a CR1 ghoul is certainly a “significant enemy”. This is an exception to the general case described above.

You’ve described a situation where a character is paralyzed and then combat moved into the next room. In this case it’s murkier, because the character isn’t actually “facing” anyone at all. The combat isn’t over, and the character is certainly still in danger — but we shouldn’t allow characters to activate their abilities just on the basis that there are enemies nearby.

On the gripping hand, one of the main purposes of GM discretion is to make sure the game is fun!

In the situation you’ve described, your solarian player is definitely not having fun. They’ve been paralyzed, sidelined, and left out of the combat. The player turns to you and says: “well, that’s pretty awful. But at least I can keep building attunement, right?”

In this situation, the right thing to do is show mercy. Let them squeeze at least a little bit of silver lining out of the awful situation they’re in. It won’t cost you anything, and they’ll have more fun in your game.

pathfinder 1e – Does the axis matter for the consideration of "Sharing an alignment component"?

Specifically in regards to the Insinuating archetype for Antipaladin, my question is really about your variant Hit the impudence characteristic.

It states:

Hit the impudence (Su):

Once a day, an insinuator can plead with the forces that empower him to punish his shared enemies. As a quick action, the insinuator chooses a target in sight to hit.

An insinuator cannot use wounds against a target that shares an alignment with the stranger he has summoned for the day.

And then continue describing the functionality exactly like any other hit (+ Cha to hit, + lvl to damage, etc.)

Essentially, at the beginning of each day, you choose a stranger who has an alignment within your step, and then you can Hurt targets that have alignments that oppose it, that is, LE can hit CG, CN, NG and TN, but not LG, LN, LE, NE or CE.

My question is, on the dual alignment axis of Good Vs Evil and Chaos Vs Law, how is Neutral applied? Specifically, does an LN creature have protection against an NE hit? Both are neutral, but of a different axis. Is the axis important for consideration of the alignment component, or is it simply neutral in either Enough shaft to thwart the wound?

How to send UI ideas to Apple for consideration

Doubletap (fast-successive) of the power button of the iPhone could be interpreted by the iPhone to invoke an application or action configured by the user (camera, etc.). Where is the appropriate forum to submit ideas as such?

Basic guidance on the AWS consideration for my web hosting.

The AWS services are so extensive and mostly advanced that I can not determine if they provide the basic web hosting I need. I've been using Linux hosting services for 15 or 20 years, but I do not see anything familiar on Amazon.

I'm with A2-Hosting now and everything is fine, but I was told that my prices will increase by 50% when my current contract ends (unless your price schedule changes +/- by the time my contract ends)

My needs are simple: I am currently paying $ 550 / year for this, but I would like to establish price stability. (my last provider went up to $ 1500 / year for this type of service)

A. I need a conventional Linux hosting service, which provides a VPS that they Keep running and updated.
B. A user control panel
C. SSL free for 9 websites.
D. 80 mb / s download speed
E. 100GB of space available for my content.
F. PHP support
G. There is no database or shopping cart.

G. I update the content almost daily with ftp using Windows Explorer. . I can not give up this open text ftp access for updates. If they pirate me, I'll start again from my local backup. It has not happened yet in the last 15 years.

Will AWS allow open text FTP?

I see that AWS has a free trial version as a learning tool, but I can not find anything that looks like a conventional basic Linux host.
