kandi X-RAY | firework Summary
Firework is an open source hardware-accelerated system designed for offloading Protocol Buffer serialization from the system's CPU. (That was a loaded sentence, I know. If I did my job correctly, by the end of this tutorial it'll make much more sense.) Generally speaking, Firework demonstrates the process of identifying components of a software application as candidates for hardware acceleration, designing hardware to efficiently perform (and replace) that computation, and building a system that deviates from the traditional paradigm of executing instructions sequentially on a CPU. Before I continue, it's necessary to give the term system a precise definition. In the context of hardware acceleration, I define a system as the combination of hardware and software that together perform a specific function. Therefore, the goal of this and any other hardware accelerator project is to improve a system's performance through the co-optimization of the hardware and software that comprise that system. It's also worth noting that the hardware community distinguishes between hardware acceleration and offloading, although the precise difference is a bit ambiguous. I classify Firework as an attempt to perform the latter since, in my design, I move the computation involved in Protocol Buffer serialization from the system's ARM CPU to a custom processor (i.e., the hardware accelerator) that's implemented in the system's FPGA fabric.

QUESTION
Im trying to learn form validation and I cannot figure out what is going on here. I am following a W3Schools tutorial and the validate form function is giving an error but it is not doing that on their example.
I tried copy and pasting the example into my project and just changing the property name and it still gives an error.

QUESTION
Python 3.10.2
I have a URL that generally appears as follows, with some slight variation (http/https, www. prefix sometimes, #params at the end to indicate things like referrer or device being displayed on, etc).
https://madeupdomain.net/u/Hypothetical_Username/Some-Random-Page-Name
The forms of the URL I'm generally encountering are either:
https://madeupdomain.net/u/Hypothetical_Username/
or
https://madeupdomain.net/u/Hypothetical_Username/Some-Random-Page-Name
What I'm interested in doing with the URL:
- Get the
Hypothetical_Usernamepart - Find out if the URL stops at the username or if there is another
/pathafter it
I've been using user = url.split('/')[4] to get the username portion of the URL. Since the URL always includes the username and the URL is usually consistent (for now), I can rely on this split getting the element I want. If the URL changes a little bit in the future, I know this'll bone me.
However, the rest of the path is optional.
If I just use url.split('/')[5], python throws an error as soon as it encounters a URL where split doesn't have a [5]th element.
So I tired to "test" for it with an if statement and it still complains and throws the error IndexError: list index out of range.
ANSWER
Answered 2022-Mar-01 at 10:49You can split the url at '/u/' and then split the last part with '/' to get the username and the path after that.

I'm using fandom module in python for my discord bot. I get this error when I request data by using page.images[0]. It should be an image url. This is the page I want to get.
ANSWER
Answered 2022-Feb-01 at 09:46I fixed it by using pymediawiki module.
This code that use mediawiki can replace fandom module by changing the api of wiki.
QUESTION
I know my post count looks suspicious but in my six years of coding I always found an answer by doing some research, this issue though has got me stumped so here goes my first post.
The problem I am facing is simple, I am using python to code a genetic algorithm for Hanabi game, while in other projects I used to print out some info normally so I can debug or ensure results are what expect them to be, in this project and for some very odd reason, whenever I use print() it does not produce an output in most cases, it does produce an output only if it is called from the main function, I will paste my code and result below:

QUESTION
In my 'show' function I have this command: point(this.position.x, this.position.y);
This does not cause a point to appear, note I have tried printing these values out directly before this point(..) call and they exist and are within the frame. I have also tried parsing them to an int and passing but no luck.
However:
- Passing e.g. 100, 100 to this function makes the point show up
- Setting this.position.x and this.position.y to e.g. 100 before point(..) call makes the point show up
- Passing e.g. 100, 100 to new Particle(random(width), height); instead of using width and height also works
- Assigning new variables to values of this.position.x and this.position.y respectively then passing those to point also does not show the point
Please find below my code, I have no idea what the issue is
...ANSWER
Answered 2021-Nov-29 at 01:02The point is actually being drawn on the canvas, it just doesn't seem obvious. This is because you're setting its y value to height which will simply place it at the very bottom of the canvas. The colors also make it hard to see where the point is drawn. The image below shows the point being drawn at (310,399).
To resolve this, change the y value to be between 0 and height. One way of achieving this is to randomize the y value as you did with random(width) for x. In my solution below, I also changed the background to be drawn with color value 151 instead of 51 for better contrast.
QUESTION
I have kind of a special problem. I am currently learning react and have fetched data from my own demo API (a Java Spring project).
However, I receive the data correctly in React. Now I am creating Components with it (Music Track Metadata). The response of the API returns an Array of Objects and one item within the object is a nested object. Now i don't know how i can extract this information to my React component.
Here is an example JSON of my response:
...ANSWER
Answered 2021-Oct-26 at 16:02So, your response.data is an array of 'tracks'. Each 'track' is an Object. You are currently destructuring your 'track' like so, in your .map() method:

I need to find most frequent value of object_of_search for each ethnicity. How can I achieve this? Subqueries in the SELECT clause and correlated subqueries are not allowed. Something similar to this:
ANSWER
Answered 2021-Oct-23 at 14:53Updated: Fiddle
This should address the specific "which object per ethnicity" question.
Note, this doesn't address ties in the count. That wasn't part of the question / request.
Adjust your SQL to include this logic, to provide that detail:

I have one csv file containing thousands of urls. How is it possible to select randomly one url from each base type url. The order of getting url can be anyway. It has to be random.
...ANSWER
Answered 2021-Oct-16 at 03:33The first thing you would need to do would be to extract the base url, which can do done using urllib.
You can then use groupby with sample to extract a random url for each base_url.

Install firework
Dell PowerEdge R720xd (server where the EDA tools are installed)
CentOS 7 (free operating system compatible with the EDA tools)
TigerVNC (VNC server software running on the server so it can be remotely accessed)
RealVNC VNC Viewer (VNC client software running on my laptop)
Download the CentOS 7 DVD ISO image. Choose DVD instead of Minimal since we'll need to install a GNOME Desktop on the server.
Log in to the iDRAC and go to the System Summary page (default page upon login).
In the System Summary > Virtual Console Preview window, click Launch. This will download a Virtual Console Client called viewer.jnlp.
Run the viewer.jnlp Java application. Your computer may complain about it being from an unidentified developer, but there's a way around this. Right click viewer.jnlp > Open With > Java Web Start (default) and click Open in the window that appears.
This will open another window, Security Warning. Click Continue.
You can never be too cautious. This will open a new Warning - Security window that asks, Do you want to run this application? I think you know the answer. Click Run.
Great, we've finally opened the Virtual Console Client! Click anywhere in the window so that its menu appears in the OS X menu bar at the top of your screen. Select Virtual Media > Connect Virtual Media. I couldn't take a screenshot of this step because when the Virtual Console Client is in focus, it captures all keyboard events. See the menu bar in the screenshot below.
Once connected, select Virtual Media > Map CD/DVD ... and select the CentOS 7 ISO image we just downloaded. Then click Map Device.
In the Virtual Console Client menu again, select Next Boot > Virtual CD/DVD/ISO. Click OK in the window that appears. This tells the server to boot from the CentOS 7 installer ISO we downloaded on the next boot.
In the Virtual Console Client menu, select Power > Reset System (warm boot). You'll see "No Signal" appear on the window followed by the CentOS 7 installer screen when the server finishes rebooting. With Install CentOS 7 highlighted, press enter to begin installation.
Follow the promts until you get to the Software Selection window. Select GNOME Desktop as your Base Environment. Select the Legacy X Window System Compatibility, Compatibility Libraries, and Development Tools add-ons in the list to the right. Click Done when your window looks like the one below.
Select a disk to install to, select Automatically configure partitioning., and (optionally) encrypt your data; I didn't. Click Done and proceed with the installation by selecting Begin Installation in the main menu.
During the installation, it'll ask you to create a user account. Make the user an administrator and set the root password. DON'T FORGET TO SET THE ROOT PASSWORD. We'll need root access when installing the VNC server daemon. Click Reboot when the installation completes and voila!
Using the Virtual Console Client from the previous section, make sure you're logged in as the user you created and open a terminal. First, let's install the TigerVNC server software.
The previous step creates a template service unit configuration file for the vncserver service in /lib/systemd/system/. We need to copy this file to /etc/systemd/system and make a few modifications in order to have systemd automatically start this service for the logged in user when the server is reset or turned on.
Using the text editor of your choice (e.g., vim), open the file and replace every <USER> instance with the name of the user you created. I created a user with the name fpga and highlight where those changes are made in the screenshot below. Also add the option -geometry 2560x1440 to the ExecStart= line replacing 2560x1440 with the resolution of the screen you plan to run the VNC Viewer client on. This will make full screen mode look pretty on your laptop or monitor.
Use systemctl to reload the systemd manager configuration.
Enable the vncserver unit instance. Note the number 5 in vncserver@:5.service was chosen arbitrarily but means the vncserver running for this user will be listening for incoming connections on port 5905.
Configure the firewall used by CentOS 7 to allow traffic through port 5905.
In the terminal, run vncserver and it'll ask you to set a password for opening VNC connections with this user. Note, this should be from the user's CentOS 7 login password.
With all the configurations made, let's make sure vncserver is running for this user before setting up the VNC Viewer client software.
Now that we have our VNC server running, let's set up the VNC client software on the device we'll use to remotely access the server (macbook for me). On your laptop, download the RealVNC VNC Viewer client, install, and open it. In the VNC Server field, enter 127.0.0.1:5900 but don't click Connect just yet.
Open a terminal and enter the following command, replacing <ip-address> with the IP address of your server and <user> with the name of user you created when installing CentOS 7.
Click Connect in the VNC Viewer client and you should see the following warning, which we can now safely ignore.
Click Continue. Enter the passowrd you set up for the VNC server and click OK.
Congratulations! We just established our first remote desktop session with the CentOS 7 server! If you hover your curser above the top-middle of the window, a menu will appear. Click on the icon in the middle to enter Full screen mode. If you set the -geometry option with your screen's resolution, it should take up entire screen. Click on this icon again to exit Full screen mode.
Quartus Prime Standard Edition
Qsys System Integration Tool
ModelSim-Intel FPGA Edition (formerly ModelSim-Altera Edition)
From Intel's Download Center, download version 17.1 of the Quartus Prime Standard Edition software and device support for the Arria 10 (parts 1, 2, and 3). Select Linux as the operating system and Direct Download as the download method (setting up the Akamai DLM3 Download Manager takes extra effort and is unnecessary for this one-time download). You have a few options for downloading the necessary files. I avoided the Complete Download since it's a pretty huge file (26.8 GB) and contains unnecessary device support. Instead, download the following files from the Multiple File Download section:
Quartus Prime Standard Edition Software (Device support not included)
Quartus Prime Device Package 1 (Arria 10)
You should now have the following tarballs sitting in your ~/Downloads (or other default) directory:
Quartus-17.1.0.590-linux.tar
Quartus-17.1.0.590-devices-1.tar
Extract Quartus-17.1.0.590-linux.tar and run the setup.sh script.
Click Next to reach the Select Components window. Select the following components:
Click Next twice to proceed with the installation. You'll receive the following Info pop-up dialog which you can safely ignore (we'll install Arria 10 device support files next):
Extract Quartus-17.1.0.590-devices-1.tar and run the dev1_setup.sh script.
If you didn't create a desktop shortcut, let's add the Quartus Prime binary (quartus) to the PATH environment variable so you can simply type quartus in a terminal to open the tool. I'll leave it to you to decide whether you want to do this permanently (i.e., editing ~/.bashrc) or temporarily (i.e., export PATH=$PATH:<path-to-quartus> in an open terminal). The path to quartus is: ~/workspace/intelFPGA/17.1/quartus/bin/.
Acquire a license. I wouldn't bother with the Self-Service Licensing Center. Instead contact an Intel licensing representative directly and ask for a license for Quartus Prime Standard Edition and ModelSim-Intel FPGA Edition. Quartus Prime Standard Edition (or Pro) is required when working with Arria 10 devices and is used to implement the FPGA hardware design. I used ModelSim-Intel FPGA Edition to run simulations and perform functional verification of each subsystem of the design as well as the hardware accelerator as a whole. Although I haven't tried, you may be able to run the simulations I've included using the free version of ModelSim (ModelSim-Intel FPGA Starter Edition).
You should now have received a license from Intel. Create a directory called license in your root directory and move the license there. I used scp to copy the license from my macbook to the CentOS 7 server (see screenshot below as an example of using this command). Accessing your email from the server directly is another option.
We need to edit the license before it can be served. First, copy and rename the license to /usr/local/flexlm/licenses/license.dat. This is where we'll tell the FLEXlm license manager to look for a license file called license.dat to serve.
Using the text editor of your choice, open license.dat and add the following lines near the top. See the screenshot below to see where I made the changes.
Now we're ready to serve our license! Run the following command to start the FLEXlm license manager and serve our license. Note that FLEXlm was also included in the Quartus Prime installation.
Run the command to start FLEXlm again and voila! You'll see a log of information from FLEXlm (lmgrd), the Altera daemon (alterad), and the ModelSim daemon (mgcld). Completely irrelevant, but I'm guessing lmgrd stands for license manager daemon.
Uh-oh! Upon further inspection, we see that FLEXlm actually failed to launch the ModelSim daemon (mgcld) at time 23:42:24:
Restart FLEXlm to successfully serve both Quartus Prime and ModelSim features this time. First, use ps to identify the currently-running lmgrd's process ID (PID) and kill it with the kill -9 command.
Open Quartus Prime. Note, if you're using version 17.1 or later, the license should automatically be recognized and you can skip ahead to step 11. Otherwise, you'll see the License Setup Required pop-up dialog appear again, but this time we're ready to specify the license we're using. Select If you have a valid license file, specify the locaiton of your license file option and click OK.
Specify the locaiton of the license file and click OK.
Voila! We now have Quartus Prime Standard Edition running with its (and ModelSim-Intel FPGA Edition's) features properly licensed and activated!
