Q: VirtualBox failed to open iso?

When I try to attach an iso, I got the error "could not get the storage format of the medium", and then (VERR_NOT_SUPPORTED), though I am pretty sure the system I chose and the iso match. I am using ubuntu 18.04 lts.

@NathanOsman If I need to build a really basic webapp but have to use python (vs go as my first choice) what framework would you recommend? Nothing seems as simple as go :(

Nathan Osman

Flask is pretty good.

I would definitely recommend starting with that.

It's very easy to get up-and-running and yet it is powerful enough to be used for large and complex web applications.

@Fabby Coming back to imgurs auto-resizing feature, see here: api.imgur.com/models/image#thumbs

> There are 6 total thumbnails that an image can be resized to. Each one is accessable by appending a single character suffix to the end of the image id, and before the file extension. The thumbnails are:

Thumbnail Suffix Thumbnail Name Thumbnail Size Keeps Image Proportions
s Small Square 90x90 No
b Big Square 160x160 No
t Small Thumbnail 160x160 Yes
m Medium Thumbnail 320x320 Yes
l Large Thumbnail 640x640 Yes
h Huge Thumbnail 1024x1024 Yes

Q: Preserve image transparency when resizing images

Whenever an image is resized on Stack Exchange using URL modifiers, any transparent elements or backgrounds will be lost in the conversion. Exactly how the missing transparency is handled can vary depending on the modifier being used, and the size of the image being converted When testing with ...

apparently you can also append e.g. ?s=64 to the image url to get a 64x64 version

I’m eager for writing a (AU) meta Q&A about this feature, I feel it’s not commonly known and useful in so many use cases.

you can't really be eager for doing something

What can I be? :)

Zanna

you might be eager to do it, or eager for it (to be created) or maybe eager for someone else to do it

interesting hat...

The kinds wanted to see it so badly for so long and we couldn’t find any reason for them not to see it, so they watched the whole thing this time (while the last times they didn’t). It’s amazing to see how they are driven by nothing but curiosity and not yet diverted by shame or feelings of guilt.

@Zanna hello

Zanna

Hi

George Udosen

I have a concern or rather an observation!

Compliments of season first of all @zanna

Zanna

Likewise :)

George Udosen

15:24

@zanna can I fire away?

Zanna

Please do :)

I may be a bit slow to reply at first

George Udosen

I observed that a reputable user had his rep put at one (1)! May i know how that happened?

Zanna

That user was suspended :(

George Udosen

I have never known that user to be mean in any way and I am really sad at that

Zanna

His rep will go back to normal when the suspension is over

George Udosen

15:27

Is there an appeal process for this kind of situation?

Zanna

I am sad too, but I know nothing about the reason for the suspension. I can only assume rules were broken

George Udosen

ok I see!

ok at first I thought perhaps it was another user with that name or a christmas prank.

Zanna

@GeorgeUdosen I don't believe so... I would think they had had a chance to talk to mods about it...

George Udosen

ok thanks for dropping by. Happy holidays

Zanna

You too, nice to meet :)

Hi everyone, I am facing problem while installing ubuntu on my HP EliteBook Folio 9470m Base Model Notebook PC, but getting kernel error can anyone please help me?

I tried to install other linux distros also but facing same problem

On my other laptops I am able to install these linux distro

PerlDuck

@GeorgeUdosen We recently talked about that here in chat (see chat.stackexchange.com/transcript/message/48175684#48175684 and the follow-ups). I find it sad, too. It's not only the user in question is put in a "penalty box" but also we will miss some great answers for the next couple of weeks.

@GeorgeUdosen I once witnessed a case over on SO. A high-rep user was suspended for a year but soon after (couple of days) they apparently considered that too much and reduced it to two weeks or so. I don't know the background, though.

Wow, it’s a long suspension this time as well.

I try to get a Necromancer badge with the following answer, supporting votes are very welcome. :)

A: Problems installing program dcm2niix on ubuntu; windows 10

If you find a package on https://packages.ubuntu.com that means you can install it using apt and this exact package name, provided you have its repository (universe in this case) activated in your software sources. If you don’t or don’t know, you can do so with: sudo add-apt-repository universe ...
