QUESTION
I'm pretty new to Python and opencv, and I would like to use opencv to crop frames from a video. The work flow is as follows: I opened up an image and get some coordinate values from mousecallback function. Since the video was taken with a cell-phone on a tripod, I would expect the region of interest should be fixed in space. Therefore, I can use the coordinate to batch process other frames. The first cropped image is done and saved as expected but I have a problem processing the other frames.
Code imported packages ...ANSWER
Answered 2021-Jun-12 at 03:48I can't test it but I think I see problem - you mess with coordinates.
get_cropped()
returns

Here is the solution for someone who faces the same issue The point to learn is that the state of my_trie in the setup function will be the state that will be used by all other tests

I'm doing a ZipInputStream request on a UTF-8 encoded zip file.
I get the data through OK, but special German characters are coming out wrong.
Using this page ( http://kellykjones.tripod.com/webtools/ascii_utf8_table.html ) I can see that my code is printing out the two individual chars from the UTF8 encoding column.
i.e. ä is UTF 0xC3,0xA4, and I am getting ä printed out (which are the 0xC3 and 0xA4 chars). Does anyone have any tips?

QUESTION
I've developed a CQRS style database access framework based on Tripod and other inspirations but targeting .NET Standard and simplifying for easier use. I want to split the IoC into separate integration packages so consumers can get the type registration I'm currently doing internally easily without being locked into a specific IoC container. My issue is I've only really worked closely with SimpleInjector so not familiar with other systems and their nuances around how they handle specific scenarios. I have an iminent need to support Autofac so thought I'd try here to see if anyone can translate.
I have the following Simple Injector CompositionRoot static class:
...ANSWER
Answered 2020-Jun-24 at 07:33I worked out the process and now have an AutoFac module. I was able to registermodule by instance of the class and also pass in the options when I instantiate. Because EntityDbContext implements the three interfaces I was registering separately in the Simple Injector scenario, AutoFac has the convenience of being able to just infer them and register with AsImplementedInterfaces()

I have a Python dictionary with dictionaries nested heavily within. There are several tiers.
What I am trying to accomplish is a function where I can enter any one of the "subcategories" values, for example, 20003482 or 200000879 and it has to return the first nested subcategory key, so for the above examples, 100003109
I am unsure about the best way to go about this, but I've tried something like

QUESTION
What instruction set architecture does an LE (linear executable) file have? The linked article says: mixed 16/32 bit.
- Does it mean that the same LE file can contain 16-bit and 32-bit code?
- How do I detect whether it contains 16-bit (8086) code?
- How do I detect whether it contains 32-bit (i386) code?
Please note that I'm aware of the CPU type field (see here) which can distinguish between 80286 and i386 (80386). However, I interpret this as a CPU type requirement, so this doesn't specify the architecture, e.g. the hex 40
is valid in both: it means inc ax
in 16-bit code and it means inc eax
in 32-bit code, and both can be executed by a 80386 CPU. I'm interested in what hex 40
means in the code of an LE file.
ANSWER
Answered 2020-May-25 at 16:46I was able to find https://www.program-transformation.org/Transform/PcExeFormat , based on which the answer is the following.
If object flag bit 13 in the object table entry is set, then it's 32-bit, otherwise it's 16-bit.
In the executable entry table, LE flag bit 1 of LX bundle type byte distinguishes between 16-bit and 32-bit.
Since there can be multiple entries in these tables, a single LE or LX file may contain both 16-bit and 32-bit code.
QUESTION
The x86 INVD
invalidates the cache hierarchy without writing the contents back to memory, apparently.
I'm curious, what use is such an instruction? Given how one has very little control over what data may be in the various cache levels and even less control over what may have already been flushed asynchronously, it seems to be little more than a way to make sure you just don't know what data is held in memory anymore.
...ANSWER
Answered 2020-May-20 at 20:12Excellent question!
One use-case for such a blunt-acting instruction as invd
is in specialized or very-early-bootstrap code, such as when the presence or absence of RAM has not yet been verified. Since we might not know whether RAM is present, its size, or even if particular parts of it function properly, or we might not want to rely on it, it's sometimes useful for the CPU to program part of its own cache to operate as RAM and use it as such. This is called Cache-as-RAM (CAR). During setup of CAR, while using CAR, and during teardown of CAR mode, the kernel must ensure nothing is ever written out from that cache to memory.
To set up CAR, the CPU must be set to No-Fill Cache Mode and must designate the memory range to be used for CAR as Write-Back. This can be done by the following steps:
- Set up an MTRR (Memory Type Range Register) to designate a chunk of memory as WB (Write-Back).
invd
the entire cache, preventing any cached write from being written out and causing chaos.- Set caching mode to Normal Cache Mode (
cr0.CD=0
). - While in Normal Cache Mode, "touch" all cachelines of the memory span to be used as CAR by reading it, and thus filling the cache with it. Filling cachelines can only be done in Normal Cache Mode.
- Set caching mode to No-Fill Cache Mode (
cr0.CD=1
).
The motivation for setting up CAR is that once set up, all accesses (read/write) within the CAR region will hit cache and will not hit RAM, yet the cache's contents will be addressable and act just like RAM. Therefore, instead of writing assembler code that only ever uses registers, one can now use normal C code, provided that the stack and local/global variables it accesses are restricted to within the CAR region.
Exiting CARWhen CAR is exited, it would be a bad thing for all of the memory writes incurred in this "pseudo-RAM" to suddenly shoot out from cache and trash any actual content at the same address in RAM. So when CAR is exited, once again invd
is used to completely delete the contents of the CAR region, and then Normal Cache Mode is set up.
Intel alluded to the Cache-as-RAM use in the i486 Microprocessor Programmer's Reference Manual. The Intel 80486 was the CPU that first introduced the invd
instruction. Section 12.2 read:
12.2 OPERATION OF THE INTERNAL CACHEExamples of UsageSoftware controls the operating mode of the cache. Caching can be enabled (its state following reset initialization), caching can be disabled while valid cache lines exist (a mode in which the cache acts like a fast, internal RAM), or caching can be fully disabled.
Precautions must be followed when disabling the cache. Whenever CD is set to 1, the i486 processor will not read external memory if a copy is still in the cache. Whenever NW is set to 1, the i486 processor will not write to external memory if the data is in the cache. This means stale data can develop in the i486 CPU cache. This stale data will not be written to external memory if NW is later set to 0 or that cache line is later overwritten as a result of a cache miss. In general, the cache should be flushed when disabled.
It is possible to freeze data in the cache by loading it using test registers while CD and NW are set. This is useful to provide guaranteed cache hits for time critical interrupt code and data.
Note that all segments should start on 16 byte boundaries to allow programs to align code/data in cache lines.
coreboot has a slide-deck presenting their implementation of CAR, which describes the above procedure. The invd
instruction is used on Slide 21.
AMD calls it Cache-as-general-storage in §2.3.3: Using L2 Cache as General Storage During Boot.
Other UsesIn certain situations involving cache-incoherency due to DMA (Direct Memory Access) hardware, invd
might also prove useful.
