I have a 3 deep array. Currently, the code will isolate a record based on one field ($profcode) and show the heading. Eventually, I am going to build a table showing the information from all the other fields. The code so far is using in_array and a function that accepts $profcode. I am unsure if (and how) I need to use array_keys() to do the next part when I retrieve the "Skills" field. I tried:

Version:

• OS lsb_release -a : Ubuntu 18.04.5 LTS
• PHP php -v : 8.0.1
• Apache apache2 -v : 2.4.29 (Ubuntu)
• MySQL mysql -v : 10.1.47-MariaDB

Problem:

I'm trying to install LAMP Stack using following article. However, I was getting HTTP 500 Error while accessing phpmyadmin from browser.

So, I tried to create symlink using ln command but it fails

ln: failed to create symbolic link '/etc/apache2/conf-available/phpmyadmin.conf': File exists

I’m working on a variant of poker which requires two decks. For statistical reasons it’s important that when shuffling the two decks a common random number generator be used. For testing I have a small main where I create an instance of the random number generator and two instances of the deck. I reference to the instance “Random” in classDeck with the statement “extern classRNG Random.”

Everything compiles OK, but I get the linker error “Deck.obj : error LNK2001: unresolved external symbol "class classRNG Random" (?Random@@3VclassRNG@@A).” If I create the instance Random in classDeck instead of in main everything compiles and links OK, but of course that would create a separate random number generator for each deck.

There is clearly something I’m overlooking.

It's a lot of code to go through, but I think the error is being created by the function "Shuffle" in Deck.cpp, near the end of Deck.cpp. That's were I have the statement "extern classRNG Random." Commenting out the line "RawDeck[i].SortParam = Random.RNGGet()" eliminates the error.

Here’s the code for RNG.h:

I'm building a candle recorder (Binance Crypto), interesting in 1 minute candles, including intra candle data for market study purpose (But eventually I could use this same code to actually be my eyes on what's happening in the market)

To avoid eventual lag / EF / SQL performance etc. I decided do accomplish this using two threads.

One receives the subscribed (Async) tokens from Binance and put them in a ConcurrentQueue, while another keeps trying to dequeue and save the data in MSSQL

My question goes for the second Thread, a while(true) loop. Whats the best approach to save like 200 + info/sec to SQL while these info come in individually (sometimes 300 info in a matter of 300ms, sometime less) using EF:

Should I open the SQL con each time I want to save? (Performance). Whats the best approach to accomplish this?

-- EDITED -- At one point I got 600k+ in the Queue so I'm facing problems inserting to SQL Changed from Linq to SQL to EF

Here's my actual code:

I have a Python dashboard built using dash, that I want to filter on either the Investor or the Fund column.

I believe it would not be possible due to security reason as stated in many other articles on StackOverflow. However, when I use the Diagram app at https://app.diagrams.net/ I realized they could ask me to save a file, and somehow keep that file reference and whenever I click Save on the app, my local file on hard drive changes (no new download).

I know it's only possible to upload/download a file and believe you cannot edit it (using Blob with FileReader etc). How do they achieve that? The app is open source but unfortunately plowing through the source code of their File Handler I still cannot find out what API they are using. I don't remember installing any plugin or app in my browser.

I also notice there is this permission in my browser so I guess it's some standard API, but even using that as keyword, all leads back to StackOverflow articles saying it's not possible.

Is it a new API I am not aware of? What am I looking for?

I made this command where u can fake hack someone but every time it edits the message too fast I'm just trying to see how can I slow it down where it just plows every single edited message where I cant see

I am developing VueJS / Express applications, getting into more advanced web dev than I've done before. I use VSCode, and develop the back end and front end in the same project. I am able to use VSCode debugger for the back end work, and use Chrome debugger for the front end.

VSCode works great. End of that story.

Chrome is powerful, but quirky. I end up debugging what is going on with the Chrome debugger quite a bit. Add to that the inscrutable Vue internals, which are always popping up, adding another level that has to be plowed through (or ignored). But the biggest issue I have is that I cannot inspect instance variables in component scripts, only variables that are local to the function that the breakpoint is in. This reduces my process to doing a lot of one-time console.log() statements, where one is in search of just a quick inspect of a 'this.[anything]' instance variable.

I've been just putting up with this for months, but lately doing some refactoring it's slowed my progress to a crawl, so I'm looking to see if there is a way I can overcome this obstacle and speed up my debugging process.

Anyone have a suggestion? Is there a way to set Chrome to enable inspecting object variables? Is there a more efficient debugging method or tool for Vue front end dev?

Other than this, the combining of front end and back end code into one project has been great. VSCode rocks.

I apologize in advance if this question has been answered already.

I'm a newb when it comes to php and css (can get along with html ok). I've been banging my head against the wall trying to get this to work with no luck so far after spending a fair amount of time on Google and various forums.

My goal is to make the background images on the slider of the homepage (http://etractorimplements.com/) clickable links.

Here is the code:
