kandi X-RAY | symbolized Summary
Symbolized provides a Hash with indifferent access, but with keys stored internally as symbols. This is particularly useful when you have a very big amount of hashes that share the same keys, and it may become inefficient to keep all these identical keys as strings. An example of this case is when you have data processing pipelines that process millions of hashes with the same keys.

QUESTION
The Stanford Encyclopedia of Philosophy cites the following example of "sentential logic" as an evidently "invalid deduction":
Premise 1: A ⊃ (B ⊃ C)
Premise 2: B ⊃ ∼C
Conclusion: ∼A
But assuming the logical operator symbolized there ("⊃") is material implication, what is wrong with the logic chain? Seems like a pretty basic nested modus tollens to me....
From the explanatory paragraph that follows in that article, the explanation seems to be that it is a valid inference in term logic, but not a valid deduction in sentential logic. But I don't see why the validity would be affected by whether the referents of the symbols be terms or sentences.
...ANSWER
Answered 2021-Dec-31 at 01:35Take A
to be true, and B
to be false. Both hypotheses are true, but not the conclusion. Hence the deduction is invalid.

ANSWER
Answered 2021-Sep-11 at 16:22As @Codo has correctly identified, this is PAC.
The upper bits of the address are not garbled, but rather contain a salted hash of the register's lower bits.
And contrary to your claims, this happens with regular segfaults too. For example, calling fprintf(NULL, "a");

QUESTION
I am learning Computer organization and architecture. While studying effective addresses and various addressing modes, I have a doubt.
Let us suppose, A two-word instruction is stored in memory at an address designated by the symbol P. The address field of the instruction (stored at P+1) is designated by the symbol Q. The operand used during the execution of the instruction is stored at an address symbolized by EA. An index register contains the value X. What will be the EA if the addressing mode of the instruction is
- direct
- indirect
- relative
- indexed
ANSWER
Answered 2021-Feb-05 at 06:36• A two-word instruction is stored in the symbol W.
• The address of the symbol is stored in W+1 and it is named as Y
.
• W+2
is the address of the next instruction. PC is used to fetch the address of next instruction which is to be executed.
• The operands used by the instruction are addressed by a symbol Z
.
• The value specified by the operand is stored in the index register which is named as X
.
Now, to get the operands used for the execution, need to determine the symbol Z
which is shown below with the addressing modes:
In Direct addressing mode, address field of the instruction directly gives the address of the operand. Therefore Y directly gives the address of Z.
Therefore Z=Y
is the direct addressing mode of instruction to calculate the Z.
In Indirect addressing mode, the address filed of the instruction gives the address in which the effective address is stored in the memory.
Here, the effective address is stored in M[Y]
and it gives the address of operands executed by the instruction.

So we got an assignment in uni to format a text. The max width of a line shoud be 68 characters and if the words dont fill the line we have to fill the empty spaces with blanks, equally distributed between far left and far right.
The Problem is when i build and run the programm it crashes but when im debugging it, it runs fine.
My Compiler is Codeblocks 17.12 and to debugg im using minGW gdb. Im pretty new to programming and know that my code is probalby not the greatest. We got the function readtext from our professor.

...ANSWER
Answered 2020-Sep-30 at 18:49[StringLength(36)]
is a validation attribute for type string
not arrays
of string
or List
. The exception is probably happening behind the scenes as it tries to validate
on your property since it is of type List
. If you want to do what I think you do, create a custom validation on your list to make sure you only have strings in your list which are less than or equal to a length of 36, then you need to either implement IValidatableObject
on your model (class) or create a custom Validation Attribute
for validation by creating a class which inherits from ValidationAttribute
. You can read more about how to implement this interface and/or create a custom attribute at MSDN: (https://docs.microsoft.com/en-us/aspnet/core/mvc/models/validation?view=aspnetcore-3.1). As a test to see if it is indeed the StringLength
attribute which is throwing the exception, comment out that particular Validation Attribute
in your code and see if it runs without error.

I have a long text (of unknown size) but I only have a fixed size space to display it. To avoid the text to overflow this space, I want it to be croped in order to make it small enough to enter in it.
For example, with the following code, we see that the text is much longer than the available space (symbolized by the box). So I would like to know how to cut the text that overflows the box, in order to shorten it (shorten to 100pt for this example).

QUESTION
I have the following problem: Imagine I have a UTF8 file where every Special character is symbolized by the REPLACEMENT_CHARACTER "�". Some part of the file could look like:
Das hier r�ckg�ngig ist das zu machen r�ckg�ngig : ist bereits geamcht Weitere W�rter gibt ers zu korrigieren Hier noch ein bl�des Wort zwei in einer Zeile G�hte und Gr��e
I wrote a PowerShell script which replaces the REPLACEMENT_CHARCTERS by the corresponding Special characters, for example "a", "ü" or "ß". The corrected text, also UTF8, will look like:
Das hier rückgängig ist das zu machen rückgängig : ist bereits geamcht Weitere Wörter gibt ers zu korrigieren Hier noch ein blödes Wort zwei in einer Zeile Göhte und Größe
The Problem is that the program where I want the text to Import to only takes "Wester European DOS (CP850)" encoded files. By the way, that was the original coding which the program has been exported and would have imported without problems if I hadn't opened the file, edited it and saved it in UTF8. So here is what happend:
I exported files from a specific program as "Wester European DOS (CP850)". [Note: Every Special character has its own REPLACEMENT CHARACTER here, so an Import would work easy and restore the Special characters]
I opened the file with an Editor of my choice and the Editor detected "UTF8" on its own which is not correct. I did not recognize, edit the file and saved it as UTF8. [Now every Special character has the same REPLACEMENT CHARACTER, its �]
I have recognized that there is something wrong and wrote a script which replaces every occurrence of � by the right Special Character in UTF8. [I think it doesnt matter how the script does this, but if so, ask]
I have the corrected UTF8 File, but as you remember, I have to Import "Wester European DOS (CP850)" to my program. The same File Encoding as it has exported the file. This Encoding ensures that every Special character has its own unique REPLACEMENT_CHARACTER. So how do i got back to this by PowerShell?
Here are some more Information. The Line in which the script Reads in the file i want to correct is:
...ANSWER
Answered 2020-May-05 at 11:13Given that you say that you've fixed the UTF-8-encoded file (so that it contains the original characters), all you need is to transcode the UTF-8 file back to code page 850
(CP850):
If your system's active OEM code page is 850

QUESTION
I've created the below figure in R to visualize my raw data and predictions from a model that I ran. Predictions are given as lines and raw data as circles. Data from 2018 are currently visualized as open circles or solid lines while 2019 data is visualized as closed circles and dotted lines. Marine fish data is anything black while freshwater fish data includes anything grey. As it stands, the legend is a little funky to understand. I would like to do 2 things.
Rather than having Direction symbolized in the legend as points and lines, I would like just a rectangle showing the respective colors.
I would like to separate the Year symbology. I would like it formatted like this:
solid line (white space) 2018 (white space) solid circle
dashed line (white space) 2019 (white space) open circle

...ANSWER
Answered 2020-Apr-10 at 23:33There is something called Transmitter
in your lmer()
call which is not found in the data you provided. But since the question is just about plotting, I created a new simple linear model called lm1
. The lines aren't in the right place, but should be close enough to get the plotting points across.
To answer your questions:
- See
override.aes
e.g this answer - Not sure if this is possible, at least without an overly complex solution. I changed the shapes to be filled triangles so it is easier to distinguish up vs down as well as color. I also made the lines slightly thinner (
size = 1
) which I think helps with legend clarity.
