HP Proliant – Replace the HP Smart Array RAID controller with a new generation controller (for example, 410 -> 420).

I have a faulty P410 Smart Array Controller in my G6 ProLiant, so I decided to replace it. Since I want more flexibility, I do not replace it with another P410, but with the subsequent P420 (much of the SAAP functionality comes with no additional license fees).

Apart from the fact that the P420 is a PCIe 3.0 card, while the P410 and my server only provide PCIe 2.0, can further incompatibilities occur?

I read a statement from HP that this should be technically possible. But can someone confirm this from their own experience?

Code Generation by Search – Software Engineering Stack Exchange

Hello, I'm looking for a software that generates code this way.

class Test{
function createObj1(){

function createObj2(){

Imagine, I want to add obj3. The result should be:

class Test{
function createObj1(){

function createObj2(){
function createObj3(){

so it searches class Test{ then find that } then advances the new data and …

harmonic numbers – generation function of the series $ sum limits_ {n = 1} ^ infty H_n ^ {(m)} binom {2n} {n} x ^ n $?

I want to find the generation function of infinite series $$ sum limits_ {n = 1} ^ infty H_n ^ {(m)} binom {2n} {n} x ^ n = ?, $$ from where $ H_n ^ {(m)} $ is a generalized harmonic number, defined by $$ H_n ^ {(m)}: = sum limits_ {k = 1} ^ n frac {1} {k ^ m} $$
and $ H_n = H_n ^ {(1)} $ is the classical harmonic number. It is known that for $ m = 1 $. $$ sum limits_ {n = 1} ^ infty H_n binom {2n} {n} x ^ n = frac {2} { sqrt {1-4x}} log left ( frac {1 + sqrt {1-4x}} {2 sqrt {1-4x}} right), $$
See https://cs.uwaterloo.ca/journals/JIS/VOL19/Chen/chen21.pdf. But for every positive integer $ m $What is the generating function?

To unlock the 5th Generation iPod Nano

My daughter played with her 5th generation iPod Nano and somehow locked it up. Whenever the screen is turned on, the image of a padlock appears. I read that you can connect it to the "original" computer where the iPod was set up, but it's been so long since I'm not even sure if there's a computer. In any case, this means that this is only required if you have forgotten the unlock code.

Update: After playing with it for too long, I noticed that when you hit the round circle in the middle, you'll see a four-digit code to enter. But I have never entered a code, my daughter claims that she did not. I do not know which computer it was originally set up for this thing.

unity – How to execute a context-sensitive mesh generation at runtime

In the game I'm trying to make, I essentially generate an infinitely-generating maze that has no dead ends and every corridor has the same width.

I have succeeded in creating this system, but once I have created the floor tiles to go on, I have to create some walls. These walls surround the floor tiles and prevent you from leaving the floor tiles. The system with which I make these walls at the moment is very inefficient and superfluous. Therefore, I would like to find a better way to do this.

My current system for making these walls:

First, a Floor Builder creates all the required floor tiles, then I have a Wall Builder game object with lots of empty game objects in a single row, each with a script attached to it to see if there is a collision on the current tile. If there is a bottom plate, nothing happens, otherwise a wall play object is created, which is essentially a 1x1x1 cube with a collider attached to it. Once all checks are completed, the parent game object is moved up one tile and the process repeats.

If the player is out of range of the walls left by a garbage clearing object, they have just been destroyed.

This system can be improved in terms of code by using arrays instead of multiple game objects. However, this would not improve performance because the cause for the performance degradation on slower devices is that many game objects must be created and tracked. The whole system is very inefficient and produces about 100 to 500 game objects that are later destroyed.

I have attached a picture to give an idea of ​​how the system works. Ignore the cubes and other entities.
a working representation of my current system

There are other solutions that I have studied and implemented

One-line builder:

Basically, I place a single game object on the border that starts and stops when a player is nearby or not. It goes from right to left and checks every 1 unit of space on a groundstone and creates a wall if there is none. This was a much more efficient but slower solution that I later improved.

Smart Single Line Builder:

It's mostly the same as the previous one, but when it's in an empty spot, a raycast is triggered on the left. When this Ray encounters a tile, the information obtained with the current coordinates is used to make a single line into a large wall. Multiple Walls This system worked much better, but was still so slow that the player could run faster, as the system can make walls.

The type of system I would like to have:
A simple quad, located under the floor tiles and moving with the player.
The quad is essentially pulled up in places where there are no floor tiles. I have no idea how to do this.

Backend – tracking likes during feed generation

I'm creating an application that contains a feed system for users. I'm currently using a serverless architecture (AWS Lambda + DynamoDB) as the backend. Once the user creates a new post, the values ​​in the Posts and Users tables are updated. The feed is generated by the automatically filled-in GSI (DynamoDB function). Once the API is called, the response is generated from the index.

The schema that corresponds to the information in the tables is as follows:
& # 39; users & # 39; table: liked_posts_list (Map) (The posts that the user likes)
Posts table: liked_users_list (Map) (The user IDs of the users who liked the post)

The problem starts here when the user calls the feed API and returns a list of 10 posts. However, I can not find a way to track the posts that the current user has already liked.

Any solutions would be appreciated.
