问题 Turns out I misinterpreted wear leveling, I initially thought by accessing the drive as RAW I would lose this feature but as its a feature on the controller this explains why i am hitting millions of writes to the 'logical sector' I am testing I am writing an application where I will be utilizing a RAW disk partition like a circular buffer, ie no filesystem. I need somewhere to keep track of my read/write buffer heads that is persistent across boots, I was thinking i can create another

问题 When using jq to process JSON, I often lose the overview due to long JSON objects. Thus, something like jq . | less would be nice. However, although the above works, the nice coloring by jq is gone. Is there another way to read jq 's output line by line, or window by window, without having the terminal spammed with the full JSON object? Edit: This did not work for me: echo '{"hello": "world"}' | jq . | less -C 回答1: Use the jq -C (colorize) option, with more -r or less -r . 回答2: report.json is

问题 I am trying to replicate IDLE's alt + m command (open a module in the sys path) in Notepad++. I like Notepad++ for editing (rather than IDLE), but this is one feature I cannot find. When alt+m is pressed, I want it to run a program that asks for a module (that's fairly straightforward, so I can do that). My problem is finding the module and then opening it in Notepad++, not simply running the program. In addition, I want it to open in the same instance (same window) in Notepad++, not a new

问题 The solution consists of three classes: the SongGenre, the Song and the Library (+ Program). I am just following the instructions so most of coding comes from my lectures and the book and not much of the experience. It is what what you see and I am not really proud of it. Pointers are really appreciated. The main one is why the enum values can not be seen in another classes? This code has been fixed (see comments). namespace SongLibrary { [Flags] enum SongGenre { Unclassified = 0, Pop = 0b1,

问题 Decoding a byte stream into a text stream is easy: import io f = io.TextIOWrapper(io.BytesIO(b'Test\nTest\n'), 'utf-8') f.readline() In this example, io.BytesIO(b'Test\nTest\n') is a byte stream and f is a text stream. I want to do exactly the opposite of that. Given a text stream or file-like object, I would like to encode it into a byte stream or file-like object without processing the entire stream . This is what I've tried so far: import io, codecs f = codecs.getreader('utf-8')(io

问题 Following program compiles successfully and print 1000 without even calling a foo() function from our main() function. How is it possible? #include<stdio.h> void foo() { #define ans 1000 } int main() { printf("%d", ans); return 0; } 回答1: #define is run by the preprocessor which is staged before the compiler. After the preprocessor is done, the code will look like this: /* Everything that is inside stdio.h is inserted here */ void foo() { } int main() { printf("%d", 1000); return 0; } And this

问题 I am having some issues on reading a binary (unformatted restart file ~2GB ) written within a Fortran program, by the call here below: open(unit=1,file=opfile,status="unknown",form="unformatted") ! write(1) t ! write(1) Rho, Rho_ut, Rho_ur, Rho_uz, Rho_Ya ! close(1) that has been compiled with ifort on an Intel Xeon Phi 7250 CPU (KNL) architecture. When the same code, that has now been compiled with gfortran on an IBM POWER9 AC922 architecture, read this file with the call here below: open

问题 I am trying to upload huge files to S3 using BufferedInputStream and providing it with a Buffer size of 5MB but the performance of the application is hindered because of the network speed/amount the available data to read is limited like mentioned in this answer link (limited to 1MB). This makes me upload 1MB as part size at a time to s3 using UploadPartRequest which increases my time to upload. So, is there any other better and fast way to upload to S3 using FileInputStream as a source. Is
