QUESTION
in SQL Loader, I wanted to ask if anyone knows the limits on how may processes in an OS can be initiated at one time?
For Example, I have code which spins off 20 processes to load 20 sets of data at the same time, and each process spins a new SQL Loader.
Each set to the same table in oracle. So at first call, the SQL Loader.exe on the OS is given 20 things to load.
Would that result in 20 separate instances of sqlldr processes ? or does SQL Loader queue each call to a singular process? I'm trying to determine if there's a bottleneck in this process and if I should build a way to control when each process is uploading instead of bombarding sqlldr.
ctl file is not direct load, table is not external.
Oracle 12 and Red Hat Linux Server.
I looked at this: Does Oracle sqlldr process multiple INFILE in parallel but I'm not sure where the docs are that explain that answer and i've been looking.
...ANSWER
Answered 2021-Jun-10 at 06:53SQL loader is a single process. If you want to parallelize your load, you need to run multiple sql loader processes concurrently. You will also need the parallel=true directive in your control file.
However, in many cases, it’s much easier and more efficient to use external tables.

Lately, I've been running some Jupyter notebooks in VS Code, and I've been encountering a strange issue: whenever I open such a file, I am bombarded with pop-ups that look like this:
Sometimes a few will pop up; other times it can be upwards of 10 pop-ups. What's bizarre about this is that I already have my VS Code set up properly, and I can run my Jupyter notebooks just fine. I've tried selecting the 'Modify' option and going with the default selections just to make it go away, but no dice. How do I prevent these annoying pop-ups?
...ANSWER
Answered 2021-Jun-05 at 04:56Per your new comments, can you check your default settings to see which application is targeted to open .ipynb files? Perhaps .ipynb files are linked to open (strangely) via the Setup exe.
QUESTION
I'm trying to learn a bit about assembly. I decided to start by looking at the generated assembly files from simple source code. Of course, I get bombarded by instructions that I have no idea what they mean, and I start to search for their meaning on the internet. While searching, I realized that I have no idea what assembly language I'm looking for..
Is there a way to know which assembly language gcc generates? Does this question even make sense? I am mainly interested in the assembly that my system accepts (or however I should phrase that..). See below for the generated code using gcc.
If you realize which knowledge gaps I have, please link the relevant documents to read/study.
System:
OS: Windows 10 Pro
Processor: Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz 2.20 GHz
Type: 64-bit operating system, x64-based processor
...ANSWER
Answered 2021-Apr-28 at 01:55GCC always produces asm output that the GNU assembler can assemble, on any platform. (GAS / GNU as is part of GNU Binutils, along with tools like ld, a linker.)
In your case, the target is x86-64 Windows (prob. from x86_64-w64-mingw32-gcc),
and the instruction syntax is AT&T syntax (GCC and GAS default for x86 including x86-64).
The comment character is # in GAS for x86 (including x86-64).
Anything starting with a . is a directive; some, like .globl main to export the symbol main as visible in the .o for linking, are universal to GAS in general; check the GAS manual.
SEH directives like .seh_setframe %rbp, 0 are Windows-specific stack-unwind metadata for Structured Exception Handling, specific to Windows object-file formats. (Which you can 100% ignore, until/unless you want to learn how backtraces and exception handling work under the hood, without relying on a chain of legacy frame pointers. AFAIK, it's basically equivalent to ELF/Linux .eh_frame metadata from .cfi directives.)
In fact you can ignore almost all the directives, with the only really important ones being sections like .text vs. .data, and somewhat important to make linking work being .globl. That's why https://godbolt.org/ filters directives by default.
You can use gcc -masm=intel if you want Intel syntax / mnemonics which you can look up in Intel's manuals. (https://software.intel.com/content/www/us/en/develop/articles/intel-sdm.html / https://www.felixcloutier.com/x86/). See also How to remove "noise" from GCC/clang assembly output?. (gcc -O1 -fverbose-asm might be interesting.)
If you want to learn AT&T syntax, see https://stackoverflow.com/tags/att/info. The GAS manual also has a page about AT&T vs. Intel syntax, but it's not written as a tutorial, i.e. it assumes you know how x86 instructions work, and are looking for details on the syntax GAS uses to describe them: https://sourceware.org/binutils/docs/as/i386_002dVariations.html
(Keep in mind that the CPU actually runs machine code, and it doesn't matter how the bytes get into memory, just that they do. So different assemblers (like NASM vs. GAS) and different syntaxes (like .intel_syntax noprefix) ultimately have the same limitations on what the machine can do or not in one instruction. All mainstream assemblers can let you express pretty much everything every instruction can do, it's just a matter of knowing the syntax for immediates, addressing modes, and so on. Intel and AMD's manuals document exactly what the CPU can do, using Intel syntax but not nailing down the details of syntax or directives.)

QUESTION
I have a large application, with many dynamic parts/panels/widgets. Upon stress-testing, The GUI goes blank. I doubt that the GUI thread is bombarded with events from other threads.
I have disabled all the events that I doubted, but it still goes blank. So is there like a global handler or logger to log all the events that occur in the wxWidgets main loop ?
N.B: I have around 1000 threads.
...ANSWER
Answered 2021-Apr-12 at 19:16In your application class override FilterEvent. You can do whatever logging you need in your derived method, but be sure to return -1 to allow the events to be processed as they normally would.

I use curl post to send notification to firebase. I use registration_ids to send the same notification to multiple clients. But sometimes the notification title/body for each client is different. is Is it possible to send multiple notifications with different title/bodies with the same request?
In other words is it a good idea to bombard firebase with 100 requests? or can it be done via one single request?
...ANSWER
Answered 2021-Mar-29 at 21:04What you're describing is possible in the versioned (/v1) REST API by sending a so-called HTTP batch request. This type of request essentially includes many HTTP requests into a single requests, which means each message can indeed be different.
From the linked documentation, this is an example of what the request looks like:

I found a great article with a GAS script for a stock alert system in Google Sheets. It has inspired me to build something more extensive including alerts for daily % moves but that's beyond the point.
The author recommends applying a time-based trigger so the receiver gets a real time email alert when the stock hits the predefined target price. The script works great, but has one problem: it will send an email during every cycle as long as the condition holds true. In other words, you will be bombarded with emails if the trigger is set to every minute.
Here's the basis script.

QUESTION
Here is how I got into this mess.
Created a React-Redux ASP NET CORE 5 project from the template.
This version was completely outdated and I didn't want to clean up to basic so what I did was, delete the entire ClientApp folder, and Created a new react app using CRA with npx create-react-app clientapp --template typescript
Now This generated a working react app which starts fine with npm start. However, when I open the project in Visual studio, I am bombarded with so many errors.
I have tried almost all possible solutions I could find, I have set skipLibCheck : true in tsconfig.json , below
ANSWER
Answered 2021-Jan-15 at 16:38Ok I managed to dig in and solve this,
- Using typescript react SPA is just asking my .net app to run npm commands and nothing else.
- Typescript NuGet Package is used for intellisense in Visual studio.
- Typescript NuGet package doesn't read the
tsconfig.jsonfile at all. It takes values from the proj config which has its own section of settings. - Even if your react app builds fine from command line since VS 2019 uses typescript nuget pkg for intellisense (it is not used for build at all, npm script is run for the build and dev) so you need to match the general
tsconfig.jsonwith configuration matching from https://www.typescriptlang.org/docs/handbook/compiler-options-in-msbuild.html - So my config looked like this.

Deploy the CloudFormation stack in the us-west-2 region:
In a work directory, run bombard-setup. This will create a ./config.json file with information about your newly created CloudFormation Stack. (Use bombard-setup -s StackName if you did not use the default stack name.)
If you would like to make changes to the CloudFormation template, do not wish to run the template from the above link, would like to use a region other than us-west-2 or would like to build your own lambda, use the following steps.
The source for the lambda script can be found in lambda/src. Build your own lambda by calling npm run build. The resulting index.js will be in lambda/lib. The zipped file will be in lambda/lib/zip. You can aquire an already zipped lambda function from https://s3-us-west-2.amazonaws.com/giftbit-public-resources/cloudformation/bombard/lambda/bombard.0.1.0.zip. Upload the zipped file to an s3 bucket you control, in the region that you wish to use. You will need to change the LambdaZipS3Key and LambdaZipS3Bucket parameters of the CloudFormation template to point to the new zip file.
