kandi X-RAY | rusty Summary
Rusty is a light-weight, user-space, event-driven and highly-scalable TCP/IP stack. It has been developed to run on a EZChip TILE-Gx36 processor. A simple web-server using this new framework got a 2.6× performance improvement, when compared to the same application layer running on the new reusable TCP sockets introduced in Linux 3.9. The web-server was able to deliver static HTML pages at a rate of 12 Gbps on a TILE-Gx36 powered device. Currently, the stack only works on the TILE-Gx microarchitecture with the mPIPE user-space network driver. The software is licensed under the GNU General Public License version 3, and has been written in the context of my Master's thesis for the University of Liège.

QUESTION
Although I am very rusty on my VBA, I have saved sheets to new workbooks many times before. This code is failing with the error code "Method 'SaveAs' of object '_Workbook' failed"
...ANSWER

QUESTION
I haven't worked with VBA for a while, so my skills are a bit rusty. I've managed to put together a small script that will update the Date Contacted
and Date Modified
column I have in my excel sheet If I were to change the respective cell in column A. For all cells in column A, I set up a List by using the Data Validation tool. List = A, B, C, D
.
The script should input the current date in Date Contacted
(column H) when one of the list items is selected. If the cell is changed to a new item a message box will ask if the user wants to commit the changes. If yes, the Date Modified
(column I) will be updated. If no, Column A should revert back to it's original self and neither one of the Date columns should be updated.
There are no bugs in the code, but when prompted to answer yes or no, clicking "no" continues to loop back to the message box. I am stuck in the loop and unsure how to escape.
...ANSWER
Answered 2021-Jun-09 at 18:11You need to turn off events before making any changes to the worksheet via the macro. Changes trigger the event and when your event makes changes, it re-triggers the event resulting in a loop, or in your case, a conditional loop.

QUESTION
Im currently getting back into using R, but its been a while so im a little rusty.
I have the following code for making plots using ggplot2:
...ANSWER
Answered 2021-May-25 at 22:44If you want to use one color shade for each range of values, you can create a grouping (factor) column with levels on the condition of PAH16Cons
values <100, 100-500, or >500. Afterwards, use this column for the color
aesthetics in the ggplot
and use scale_color_manual(values=c("green", "yellow", "red"))
to customize the color.
QUESTION
I'm a bit rusty so there's probably something obvious, but I'm setting up a form where I want to hide a row when a checkbox is ticked but the if statement I'm using to check the actual contents of the cell against a predetermined "VALUE" is not triggering. The log above prints both out as "true", but then the if statement is never entered. What am I missing?
...ANSWER
Answered 2021-May-25 at 15:24Findings:
The VALUE
(contains a string
value "true") is not matching the value of cellValue
(contains a boolean
value true) on Line 17 and it is the reason why your code does not work:
QUESTION
I think I'm getting rusty, so please bare with me. I'll try to be brief.
Q1. When trying to copy buffers, say buf2 to buf1, does the following check suffice against aliasing?
...ANSWER
Answered 2021-May-21 at 13:21I believe that the term "memory areas overlap" is used more frequently.
There is no portable way of doing this kind of pointer comparisons. Standard library implementations have to compare the pointers but in this case the author of the library knows exactly how this comparison works.
Most popular glibc implementation use unsigned long long
or unsigned long
integers to compare the pointers (or rather perform the address artthmetics).
Q2. If so, can we selectively use either memcopy() or memmove() depending on the case, like this
It makes no sense as remove checks it itself. Most implementations I know do not follow the C standard way of moving memory areas - ie do not create any temporary arrays only decide in which direction to copy the memory areas. If memory areas do not overlap the copy operation is the same fast as when using memcpy
.
Most popular implementation (gnu C library glibc):
QUESTION
I code mostly client-side these days, so my PHP is rusty and I would prefer a pure PHP design in this particular case.
I don't need any client -side code for this. I want to read a lot of text files, extract some data and insert it to a MySql database.
- this could potentially take quite some time, so
- I want to
echo()
some indication of progress. Also, - I am concerned that it might take longer than the default 30 seconds, but I don't like to mess with that limit, in case my script hangs.
In order to do #2, I would normally use header('Refresh:1');
, but what if that refresh happens in the middle of the MySql INSERT
operation?
I suppose that before INSERT
, and on page reload, I could just COUNT
MySql table entries, to determine where begin processing the next text file.
Alliteratively, I could reload the page every few iterations of the loop, after the INSERT
has been done, but how, since I could not use header('Location:X');
as I have already echo()
ed the progress. Perhaps I could somehow fake a form submission? But, that feels hacky.
This seems to be a generic design pattern and I am sure that better brains than mine came up with an elegant solution long ago. Can someone tell me what that solution is? Preferably pure PHP. I have searched, but can't find anything.
At the moment, I am going with a JS solution: echo '';
, but would prefer a pure PHP
ANSWER
Answered 2021-May-08 at 14:44For this, I would use import.lock file. Here is my suggested workflow:
- When the user starts processing some data I create import.lock file, in this file we could write how many records we processed already AND the most important index of the last processed batch. It's up to you how you create batches creating strategy, you can implement it with temporary .json files, for example, join 3 big files and split it into small chunks.
- I assume you already implemented files reading and chunking, so for example we can make foreach and every iteration put some data into MySQL.
- So as I said before every iteration we updating import.lock with processed chunk number. At the moment when foreach ends we deleting import.lock file or clearing it.
- Every iteration we refresh the page with a simple PHP refresh and after refresh reading the import.lock file, taking the last imported batch index, and start again from next.
For progress to implemented you count all created junks (chunk1.json, chunk2.json ...), and let's say you we 100 chunks and we processed 15 already, import.lock have a value of 15 so it means 15% done. After refresh we taking 16 chunks (chunk16.json).
After every junk is done we delete it from file system.
Implementation example
Here is my implementation example, tested and working: Link to the repository: https://github.com/RomkaLTU/php-progress-case You still need to implement JSON files generation. I have used session in this example to track progress as user Mawg says reinstate Monica suggested.
And you may need to adjust header("refresh: 2") and chunk size.

QUESTION
I'm trying to code a Discord bot but my C# is a bit rusty at the moment. I'm trying to make it so someone can send an alert to the admin console by doing a command in a channel.
The commands work by doing -conalert (the message) but, at the moment it only works if it's a one-word message.
I remember using this function for a similar project that I since have lost and it worked like a charm.
