kandi X-RAY | Unlucky Summary
The player ventures and battles monsters in maps with various themes. Currently there are three available worlds all with 10+ levels in each world. In these maps, the player will have to defeat monsters and find a star tile to complete the level. Monsters may drop items that can improve the player's strength. These items may be sold in the shop for gold or enchanted to increase their power. There are currently 100+ items dropped by monsters and sold in the shop. The battle system is based on turn-based mechanics. The player is given four randomly generated moves with each color corresponding to a different type of move. The player also has access to special moves that they can choose in the menu. Special moves give bonus effects to the player's attacks or affects the enemy. The player also has an option to run from the battle at a very low chance of success.

QUESTION
I am reading about blue green deployment with database changes on Kubernetes. It explains very clearly and in detail how the process works:
- deploy new containers with the new versions while still directing traffic to the old containers
- migrate database changes and have the services point to the new database
- redirect traffic to the new containers and remove the old containers when there are no issues
I have some questions particularly about the moment we switch from the old database to the new one.
In step 3 of the article, we have person-v1 and person-v2 services that both still point to the unmodified version of the database (postgres v1):
From this picture, having person-v2 point to the database is probably needed to establish a TCP connection, but it would likely fail due to incompatibility between the code and DB schema. But since all incoming traffic is still directed to person-v1 this is not a problem.
We now modify the database (to postgres v2) and switch the traffic to person-v2 (step 4 in the article). I assume that both the DB migration and traffic switch happen at the same time? That means it is impossible for person-v1 to communicate with postgres v2 or person-v2 to communicate with postgres v1 at any point during this transition? Because this can obviously cause errors (i.e. inserting data in a column that doesn't exist yet/anymore).
If the above assumption is correct, then what happens if during the DB migration new data is inserted in postgres v1? Is it possible for data to become lost with unlucky timing? Just because the traffic switch happens at the same time as the DB switch, does not mean that any ongoing processes in person-v1 can not still execute DB statements. It would seem to me that any new inserts/deletes/updates would need to propagate to postgres v2 as well for as long as the migration is still in progress.
ANSWER
Answered 2021-May-22 at 19:46Even when doing blue-green for the application servers, you still have to follow normal rules of DB schema compatibility. All schema changes need to be backwards compatible for whatever you consider one full release cycle to be. Both services talk to the same DB during the switchover time but thanks to careful planning each can understand the data from the other and all is well.
QUESTION
Having an intent to study a sort algorithm (of my own), I decided to compare its performance with the classical quicksort and to my great surprise I've discovered that the time taken by my implementation of quicksort is far not proportional to N log(N). I thoroughly tried to find an error in my quicksort but unsuccessfully. It is a simple version of the sort algorithm working with arrays of Integer of different sizes, filled with random numbers, and I have no idea, where the error can sneak in. I have even counted all the comparisons and swaps executed by my code, and their number was rather fairly proportional to N log(N). I am completely confused and can't understand the reality I observe. Here are the benchkmark results for sorting arrays of 1,000, 2,000, 4,000, 8,000 and 16,000 random values (measured with JMH):
ANSWER
Answered 2021-May-18 at 21:03Three points work together against your implementation:
- Quicksort has a worst case complexity of O(n^2)
- Picking the leftmost element as pivot gives worst case behavior on already sorted arrays (https://en.wikipedia.org/wiki/Quicksort#Choice_of_pivot):
In the very early versions of quicksort, the leftmost element of the partition would often be chosen as the pivot element. Unfortunately, this causes worst-case behavior on already sorted arrays
- Your algorithm sorts the arrays in place, meaning that after the first pass the "random" array is sorted. (To calculate average times JMH does several passes over the data).
To fix this, you could change your benchmark methods. For example, you could change sortArray01000() to
QUESTION
I recently came across this coding challenge - The Unlucky number 13. (The last problem in the section)
Problem Statement:
Write a program to calculate the total number of strings that are made of exactly N characters. None of the strings can have "13" as a substring. The strings may contain any integer from 0-9, repeated any number of times.
Input: N is taken as input where 0<= N <= 1000000009.
Output: The output should be the answer modulo 1000000009.
My Solution:
I tried to solve it using a simple equation I came up with.
ans = 10^n - ((10^(n-2)) * (n-1))
Subtracting the possibilities with 13 as substring from the total number of possibilities.
I wrote the code in Swift. It works when N is small. But I get a runtime error on submission (probably when N is large).
Here is my code:

I have a Python function [1] which requires the file path pointing to the file it has to process as an argument. However, I have a string variable containing the contents of the respective file. I don't want to create a file only to read it with said function and then delete the file.
Is there a way to pass a variable instead of a file path pointing to a file with the same contents?

QUESTION
I wanna point that I am new to Graphql and I am probably missing something obvious. I would like to do something similar to a shop's order system. When a customer buys something, two things are done: (1) The money is decreased from his wallet and (2) an order is added to his order history. As of now, I modelled the wallet and the order history as two types in the GraphQL schema.
Point 1. Ideally, I want to have a transaction. If either the wallet update or the order creation fails, the whole should fail. From what I understood, to archive this it will suffice to have a single mutation that does both the updates, as pointed in this answer. So, have I understood it correctly and something like this works like a transaction (rolling back in case of failure)?
...ANSWER
Answered 2021-Mar-31 at 06:51It's a question for the database behind your AppSync. It's maybe DynamoDb, or RDS. Typically, you need only one mutation which performs a customer purchase, including
- Deduct money from the wallet
- Deduct a number of items from the inventory
- Add/Update an order record (orderId, userId, numberOfItems, status)
- Add a purchase record (orderId, purchaseId, more purchase info)
All of them are performed in a single transaction. If your DB is an RDS, then you can easily figure out the average number of items by a SQL query on the Order table. The number is aggregated in real-time, and there is no race condition.
On the other hand, if it's DynamoDb, there are many options in this answer. Race conditions in DynamoDb can be a different problem, and one solution I know is conditional update.
One mutation should be enough for your case. The mutation purchaseWithoutOrder is for purchases without an order.
QUESTION
So I have been against a wall for this one for a while now.
My requirement is to play .mp4 video file in a wpf application. Sounds simple enough, right?
At first, I used built-in MediaElement class and everything worked.
But it turns out, MediaElement is based on Windows Media Player, and for people (myself included) who are using Windows 10 Pro N (or KN) versions, which are basically stripped-down versions of Windows 10, videos are not playing, because Windows Media Player is not included.
That is also reported by attaching an error callback to MediaElement, resulting in message:
"Windows Media Player version 10 or later is required"
Of course, one option is to show user a message and a link to download the feature pack (https://www.microsoft.com/en-us/software-download/mediafeaturepack), which includes Windows Media Player, but in all my years using Windows apps, I have NEVER seen any app do/ask that. It is also wrong - the feature pack comes with alot more than just WMP and user might not want to bloat their system with unnecessary apps. That's why user chose Windows 10 Pro N (or KN) in the first place.
But then - how do other apps do it? How are videos on Slack, Discord apps played on my Windows 10 Pro N?
A bit of googling and general solution is to use VideoLAN.LibVLC.Windows framework, because it is open-sourced, well maintained and has proven itself over the years on multiple platforms.
Ok, I get it's nuget package, and since it is native code, I also download a wrapper libraries to use it in WPF - LibVLCSharp and LibVLCSharp.WPF.
I have successfully integrated video playback, everything works in Debug version.
Now it's time to test it in Release version. I create a new Setup project, build it, install it.
So here's the problem:
My app runs just fine, but when I get to the section where video is supposed to play, I get an exception error:
...ANSWER
Answered 2021-Feb-25 at 15:50So a few things:
Ok, I get it's nuget package, and since it is native code, I also download a wrapper libraries to use it in WPF - LibVLCSharp and LibVLCSharp.WPF.
You only need to reference LibVLCSharp.WPF and VideoLAN.LibVLC.Windows, LibVLCSharp is a dependency of the .WPF project
I check the Debug version's folder (because it was working just fine there) and I see that I also have a libvlc folder being generater there, with contents:
You should also have that in the Release folder too. If not, something might be wrong with VideoLAN.LibVLC.Windows or the way you're using it.
I understand, that I can create two seperate installations - one for x64 and one for x86 systems.
Yes, that would avoid embedding libvlc twice, that's what I'd recommend
If I delete anything from plugins folder, app crashes.
That's the way you should customize it, but you would need to figure out by yourself what you really need (you'll likely only need the "file" access plugin, no gui plugin, no mux...). I'd recommend taking a look at this documentation : https://code.videolan.org/videolan/libvlc-nuget/-/blob/master/cherry-picking.md
If that's not slim enough for you (for example, codec/libavcodec_plugin.dll is still too heavy for you), I'm afraid you'll have to build libvlc by yourself. Warning : it's not a nice walk in the park.
Perhaps there is another, more lightweight framework that can play .mp4 files?
I only know about FFMediaElement and other ffmpeg-based projects, but I'm unsure about the ffmpeg licensing, and I did not test them myself.
