kandi X-RAY | plow Summary

plow is a Go library typically used in Networking, HTTP, Bitcoin applications. plow has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Plow is a HTTP(S) benchmarking tool, written in Golang. It uses excellent fasthttp instead of Go's default net/http due to its lightning fast performance. Plow runs at a specified connections(option -c) concurrently and real-time records a summary statistics, histogram of execution time and calculates percentiles to display on Web UI and terminal. It can run for a set duration( option -d), for a fixed number of requests(option -n), or until Ctrl-C interrupted. The implementation of real-time computing Histograms and Quantiles using stream-based algorithms inspired by prometheus with low memory and CPU bounds. so it's almost no additional performance overhead for benchmarking.

            Retrieve values from deep array PHP
            Asked 2021-Apr-24 at 06:24

            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:

            One thing is that it could be because the PHPMyAdmin version and the PHP version do not work together well.

            Referencing an instance of a class created in main from another class module
            Asked 2021-Jan-25 at 22:05

            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:



            Answered 2021-Jan-25 at 21:56

            classRNG Random is local to main - it's not a global variable so isn't visible in your extern call in classDeck::Shuffle. Using an extern to share a variable is a bit odd - why not either have Shuffle take a classRNG* parameter so you can pass the same classRNG to each instance (or you could pass it in the constructor if you prefer). Alternatively you could also make the RNG a static member of classDeck so the deck will be in charge of constructing exactly one classRNG that is shared amongst all instances.



            Thread + While(true) + Entity
            Asked 2021-Jan-24 at 21:08

            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?

            Plotly-Dash: How to filter dashboard with multiple dataframe columns?
            Asked 2021-Jan-12 at 22:10

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



            Answered 2021-Jan-10 at 19:41

            I am admittedly pretty new to Dash, but from what I can tell, you can achieve what you want by extending your options list, and then using an or condition in the dff that you are displaying in the Dash App to include the Fund column.

            This is a bit brute force, and a nicer solution would be for Dash to know which columns your selected options are coming from. However, this would only be an issue if entries from different columns contained the same string (and here the unique values for Investor and Fund aren't ever the same).



            How do I let user save a file and keep editing that file in browser Javascript only?
            Asked 2020-Nov-09 at 04:07

            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 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?



            Answered 2020-Nov-09 at 04:00

            You can use localStorage to achieve this without needing any other permission from the user.

            localStorage.setItem("data", JSON.stringify(data));

            If your data is just JSON then this would work, however if you have custom data types, you can take a look here.


            Since you wanted to save the file directly to the device and edit it, you can take a look at File System Access API. This article here explains it.

            You can load the file first by using,



            Trying to slow down
            Asked 2020-Oct-28 at 22:34

            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



            Answered 2020-Oct-28 at 22:34

            Your problem is that you didn't wait between the edits.

            To wait between each edit, you can use this simple line of code between each message edit.

            await new Promise(resolve => setTimeout(resolve, 1000));

            You can change 1000 to any number of milliseconds you want.



            Accessing object variables in Chrome debugger (VueJS debugging)
            Asked 2020-Oct-27 at 21:45

            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.



            Answered 2020-Oct-27 at 21:45

            I have found a workaround for Vue, which is to place a breakpoint in the Watch section, using a button in the UI. In this breakpoint, a Watch in Chrome debugger has access to 'this' variables. Fellow dev's have told me that this is a common issue they deal with all the time. When I get more understanding on the conditions that affect this scope access problem, I'll add it.
