QUESTION
Using Nuxt 2.14.12, trying to display a dictionary using the V-FOR directive. The Code snippet below shows code trying to display the dictionary pokiAbilities. The code segment with the V-For is not being rendered and I don't know why.
...ANSWER
Answered 2021-May-11 at 01:21Maybe your pokiAbilities
has no data. You can use vue-devtool to check if pokiAbilities
has data.

In django there is a concept that makes me dazzled a bit.Why we should make a urls.py in our app folder while we have one in project folder.
what is the specific job each one do ?
how both have relation with each other e.g how do they interact with each other to make a django website ?
...ANSWER
Answered 2019-Oct-25 at 08:31The urls.py
in your project folder are the "base" URLs for your site.
You can then forward requests made on a certain route to your app's urls.py
using include
.
Here is an example :

I've been working on a little project that deals with matrix computations in C.
I was doing some testing against the code I wrote and came across some incredibly confusing behaviour.
Before I get into the question, here is some of the relevant code.
Matrix Definition:
...ANSWER
Answered 2019-Oct-02 at 00:22If I am reading this correctly, what you are doing is simply reading memory outside of the allocated arrays. This may cause a segmentation fault, but not always. This site gives some examples: https://www.geeksforgeeks.org/accessing-array-bounds-ccpp/
In general, when you ask C to read from memory, you give it a physical address. If that address exists and you are allowed to read from it, it will give you back the data stored there regardless of whether it is in your array. These could be 0 values or garbage data from variables you or other programs have written there. In your last example where you see the repeating values, it's because your program allocated memory for matrix[i] and matrix[i+1] consecutively. Therefore, when you start to read past the bounds of matrix[i], you start to read the memory from matrix[i+1].
Also, you mentioned that it was storing doubles outside of the bounds, but that's not quite correct. C does not know what type of data was supposed to be stored there, it only knows to interpret it as doubles because you told it to. If you cast everything as chars, it will read and print chars instead of doubles.
QUESTION
Can one run the same program (unmodified) on both the "desktop" OpenGL and OpenGL ES 2.0 platforms, provided that this program only performs 2D accelerated rendering?
An average Windows desktop PC and Raspberry Pi will run the program. The GL context is obtained via the functions provided by the excellent SDL2 library. And for the drawing routines a texture atlas will be used.
It would be convenient if a program could be developed/debugged on a PC and then simply be recompiled to run on the raspberry Pi. This would be no issue if both OGL platforms were mostly compatible.
Since I'm a beginner when it comes to OpenGL, I of course started experimenting with the "hello triangle" program first.
To my big surprise this triangle program works on both the desktop and the Raspberry Pi (GLES2). Save for some #include
file differences.
Dazzled by all the different OpenGL headers - and function pointer gymnastics - now I'm not sure anymore if my desktop somehow provided GLES2 (which seems unlikely to me) or that the "desktop" OpenGL version I have is simply "compatible enough" with GLES2.
It's especially unclear to me whether GLES2 is just a stripped down version of OpenGL or completely different.
Is avoiding "advanced" or missing extensions/features enough to ensure compatibility across these platforms? Or are there more things to take into account?
...ANSWER
Answered 2019-Aug-16 at 01:21OpenGLES is (more or less) a stripped down version of OpenGL (which mainly removes the old legacy cruft, and any features that may hurt battery life). There are a few very minor differences here and there, but that's largely the case.
On the Pi, you are limited to GLES. However on desktop, both NVidia and ATI support OpenGL and OpenGLES. I would imagine your SDL based app is targetting an EGL context with GLES, and since SDL wraps all of the platform specific Windowing APIs, that should just work on desktop.
If you really want to know the gory details, read on...
The way you initialise OpenGL (and GLES) is to query the graphics driver for a pointer to a function. So lets take a rubbish example:
QUESTION
I have a problem with query, please take a look. My aim is:
- I need to take all
Products
with oneImage
. Products
hasValues
which are some additional information aboute the product like specification etc.Image
andValues
can benull
- Wanna return all
Products
withImage
andValues
- For
Values
I need onlyIds
so its ok to getList of Values
ProductValues
andImageObjects
are connecting table for relationship -->Products
can have manyProductValues
alsoProducts
can have manyImageObjects
but can have oneImage
DistinctBy
is frommore linq
Question I don't know how to aggregate Values
in correct way to return list of Values
per Product
PS I'm also using more linq
...ANSWER
Answered 2019-Apr-29 at 10:25So you have a table of Products
and a table of ProductValues
with a one-to-many relation: every Product
has zero or more ProductValues
and every ProductValue
belongs to exactly one Product
, namely the Product
that the foreign key ProductId
points to.
You want (several properties of) all Products
, each Product
with its ProductValues
. After that you DistinctBy
and OrderBy
, but that is not your problem.
Whenever you want "items with their sub-items", like "Schools with their Students", "Customers with their Orders", "Orders with their Order lines", consider using Enumerable.GroupJoin
GroupJoin is in fact a Left Outer Join, followed by a GroupBy.
QUESTION
I upgraded an AWS EC2 machine 10 days ago (from t2-medium to t2-large). Again, I just upgraded today the same AWS EC2 machine (from t2-large to t2-xlarge) and after rebooting I noticed a massive loss of data (10 days of work). In fact, after changing instance type I found out it reverted to the same "state" of the machine just after doing the upgrade 10 days ago. Not less important, I have been doing snapshots periodically (twice a day), and when I try to recover from the last one, each snapshot is an exact copy of the machine after the first upgrade.
This is not the first project I have in AWS, and everytime I did a snapshot, it would always keep the very last copy of the machine. But NOT in this case. So I am really dazzled.
Can you give some hint on what could happen? Is it normal that AWS deletes data (DDBB + folder and files) when changing instance type? Do you think it might have to do with IAM policies?
Thank you
...ANSWER
Answered 2019-Apr-26 at 08:35The EC2 user guide has information about the EC2 Storage options. To summarise:
- The EC2 instance store volume is erased when the instance is stopped or terminated.
- In contrast, EBS (Elastic Block Storage) can be mounted to a running EC2 instance (c.f. a physical hard drive). EBS volumes can be detached from one instance and attached to another instance. Moreover, you can create a snapshot of an EBS volume that is stored in S3 and you can recreate EBS volumes from that snapshot that can be attached to other EC2 instances.
The EC2 user guide provides step by step instructions:
Lastly, no, this behaviour is not related to IAM policies.
