QUESTION
I am attempting to update my git repo by doing "git add ." within Visual Studio Code on my MAC. I have done this many times without issues but this time it is giving me this error "error: file write error: No space left on device" and "error: unable to create temporary file: No space left on device." Also when trying to clone another repo onto my device from github it says "fatal: could not create work tree dir 'cs1550-project1-domm2': No space left on device" I have 12.96gb left of 256gb. I do not know how I am out of space or how to free it. I just need to update my github repo for class.
This is running df -h within the VS terminal:
...ANSWER
Answered 2022-Feb-15 at 08:35It depends on where you are trying to do the git add .
As mentioned here:
The /snap mounts come from using software packages installed with Snap.
These utilize loop devices and are usually not writable.
You will get some sort of "No space on device" error when trying to write to any of these locations and that is represented in
df -h
as showing those mounts as 100% in use.
But in your case, assuming the repository is in /dev/...

QUESTION
I am writing a small utility library for me to request server status of a given minecraft host in js on node. I am using the Server List Ping Protocol as outlined here (https://wiki.vg/Server_List_Ping) and got it mostly working as expected, albeit having big trouble working with unsupported Data Types (VarInt
) and had to scour the internet to find a way of converting js nums
into VarInts
in order to craft the necessary packet buffers:
ANSWER
Answered 2022-Feb-11 at 13:45I don't know this protocol, but VarInt in protobuf are coded with the MSB bit:
Each byte in a varint, except the last byte, has the most significant bit (msb) set – this indicates that there are further bytes to come. The lower 7 bits of each byte are used to store the two's complement representation of the number in groups of 7 bits, least significant group first.
Note: Too long for a comment, so posting as an answer.
Update: I browsed a bit through the URL you gave, and it is indeed the ProtoBuf VarInt. It is also described there with pseudo-code:
https://wiki.vg/Protocol#VarInt_and_VarLong
VarInt and VarLong Variable-length format such that smaller numbers use fewer bytes. These are very similar to Protocol Buffer Varints: the 7 least significant bits are used to encode the value and the most significant bit indicates whether there's another byte after it for the next part of the number. The least significant group is written first, followed by each of the more significant groups; thus, VarInts are effectively little endian (however, groups are 7 bits, not 8).
VarInts are never longer than 5 bytes, and VarLongs are never longer than 10 bytes.
Pseudocode to read and write VarInts and VarLongs:

...ANSWER
Answered 2022-Jan-27 at 21:27Assigning to stdout
(or stdin
or stderr
) is Undefined Behaviour. And in the face of undefined behaviour, odd things happen.
Technically, no more needs to be said. But after I wrote this answer, @zwol noted in a comment that the glibc documentation claims to allow reassignment of standard IO streams. In those terms, this behaviour is a bug. I accept this fact, but the OP was not predicated on the use of glibc, and there are many other standard library implementations which don't make this guarantee. In some of them, assigning to stdout
will raise an error at compile time; in others, it will simply not work or not work consistently. In other words, regardless of glibc, assigning to stdout
is Undefined Behaviour, and software which attempts to do so is, at best, unportable. (And, as we see, even on glibc it can lead to unpredictable output.)
But my curiosity was aroused so I investigated a bit. The first thing is to look at the actual code generated by gcc and see what library function is actually being called by each of those output calls:

ANSWER
Answered 2021-Oct-09 at 07:11I got a CORS error the in console even though I've already set
Access-Control-Allow-Origin
to*
The question is:
Are you trying to enable CORS for a Lambda proxy integration or a Lambda non-proxy integration?
Enabling CORS will differ based on the integration type.
First, refer to the Enable CORS on a resource using the API Gateway console section of the Amazon API Gateway developer guide as it includes images etc.
Follow the guide for proxy & non-proxy.
If it is a non-proxy integration, you're done.
If it's a proxy integration (which I don't think it is), your request will still fail - a DELETE
request is classed as a complex request by the CORS specification.
This means that if you are making a call to this endpoint using a web app, you may have allowed all origins but you haven't specified which HTTP methods to allow (which the web app will request for in the form of a preflight
request before the DELETE
request).
So you'll need to also set the Access-Control-Allow-Methods
header to *
to allow HTTP DELETE
in the response returned by your Lambda:
