QUESTION
I'm running into AggregateError: EMFILE: too many open files
while streaming multiple files.
Machine Details: MacOS Monterey, MacBook Pro (14-inch, 2021), Chip Apple M1 Pro, Memory 16GB, Node v16.13.0
I've tried increasing the limits with no luck. Ideally I would like to be able to set the limit of the number of files open at one time or resolve by closing files as soon as they have been used.
Code below. I've tried to remove the unrelated code and replace it with '//...'.
...ANSWER
Answered 2022-Jan-02 at 04:41To prevent pre-opening a filehandle for every single file in your array, you want to only open the files upon demand when it's that particular file's turn to be streamed. And, you can do that with multi-stream.
Per the multi-stream doc, you can lazily create the readStreams by changing this:

ANSWER
Answered 2021-Oct-15 at 16:32From the actual behavior I can suppose that the container is based on Unix-like image. Path separator is /
in such systems.
To build an environment-independent path which works inside and outside of the container you need the following steps:
- Mounting of host folder to container directory.
- Environment variable inside and outside the container.
I can show an example of how this is achievable via docker-compose
tool and its configuration file docker-compose.yml

QUESTION
So i am currently on 14 day internship and my job is to redesign a webpages, however these webapges are made so they display links to a files in a folder and once you click on these files you download them.
My question is -> there a way of how I can change the style of this page with an external CSS file ? My problem is I don't know PHP at all and don't have time to learn it, so I don't know what these files exactly do, but I know that at the botom there is HTML code being passed on the site, I tried changing the CSS file in the HTML , but it didn't change anything and this is how the page was displayed.
This is the link to the image: https://imgur.com/skjQEk6
And this is the code that was located in the same folder as the .xls files
I am sorry for long code, I don't know how to shorten it.

QUESTION
I am very confused. I need to read binary files (.fsa extension by Applied Biotechnology aka ABIF, FASTA files) and I ran into a problem reading signed integers. I am doing everything according to this manual https://drive.google.com/file/d/1zL-r6eoTzFIeYDwH5L8nux2lIlsRx3CK/view?usp=sharing So, for example, let's look at the fDataSize field in the header of a file https://drive.google.com/file/d/1rrL01B_gzgBw28knvFit6hUIA5jcCDry/view?usp=sharing
I know that it is supposed to be 2688 (according to the manual, it is a signed integer of 32 bits), which is 00000000 00000000 00001010 10000000 in binary form. Indeed, when I read these 32 bits as an array of 4 bytes, I get [0, 0, 10, -128], which is exactly the same in binary form.
However, if I read it as Integer, it results in 16809994, which is 00000001 00000000 10000000 00001010 in bits.
As I understood from multiple forums, they use Swap and htonl functions to convert integers from little-endian order to big-endian. They also recommend using BSWAP EAX instruction for 32bit integers. But in this case they work in a kind of wrong way, specifically: Swap, applied to 16809994, returns 16779904 or 00000001 00000000 00001010 10000000, and BSWAP instruction converts 16809994 to 176160769, i.e. 00001010 10000000 00000000 00000001
As we can see, built-in functions do something different from what I need. Swap is likely to return the correct result, but, for some reason, reading these bits as an Integer changes the left-most byte. So, what is wrong and what do I do?

QUESTION
I'm trying my hardest to make this work but it just seems lite it doesn't want to.
The premise is simple. i'm trying to use fgetc to read a file and write the result in an array, stopping at any \n or EOF. It reads the line as intended but, for no apparent reason, as soon as the line ends, the program gets caught in an infinite loop. i tried using fgets, getline and even fscanf (i know it's not a good idea, but that was really my last one)
This is my fgetc attempt:
...ANSWER
Answered 2020-May-13 at 14:02You have a few problems here.
The fgetc
function returns an int
, not a char
. The reason for this is that EOF
is typically -1, which falls outside the range of a unsigned char
which is returned after casting to an int
in the normal case.
Change scan
to an int
to fix this.

ANSWER
Answered 2020-May-05 at 20:17Thanks to @SertacAkyuz for reminding me about file system redirection - trying to access %Windir%\system32 from a 32bit program will be redirected to %Windir%\SysWow64 which doesn't contain the dns folder.
You can use the virtual alias %Windir%\Sysnative to gain access to the actual system32 folder from a 32bit application, and that works for the above case. so browsing to %Windir%\sysnative\dns allows me to enumerate the folders correctly.

I made decorators to cache the data and in particular to list the files contained in a cache file. I specify that my code works perfectly but I dont know if it is a good practice because I decorate a method of my class with my decorator "@ cache.listcachedir (...)" which in reality does not call upon my method but return a result (see code above).
