QUESTION
I am used to program having the file browser on the left of the code and the outline on the right. However, in Visual Studio Code it seems that I can only have both things on the same side. Is there any way to have them in different sides (like in the image, that comes from eclipse)?
Thanks,
DMR

I have a Jboss CLI command which I'm trying to implement in Java using the DMR library. The step involves downloading an attachment (display/save), however there's no documentation available anywhere. Any help is appreciated.

QUESTION
I was looking into compiler bootstrapping, and I looked at how Golang implements bootstrapping from source, i.e., by building the last version of Golang implemented in C and using the generated executable to compile newer Go releases. This made me curious as to how the same could be done with C. Can you construct a C compiler on a computer with literally nothing present on it? If not, then how can I trust that the binary of the compiler I use doesn't automatically fill the binaries it compiles with spyware?
Related question, since the first C compiler was written in B and B was written in BCPL, what was BCPL written in?
...ANSWER
Answered 2021-Jan-16 at 15:50You can write a really feeble C compiler in assembly or machine code, then bootstrap from there.
Before programming languages existed you just wrote machine code. That was simply how it was done.
Later came assembler, which is like "easy mode" machine code, and from there evolved high-level languages like Fortran and BCPL. These were decoupled from the machine architecture by having a proper compiler to do the translation.
Today you'd probably write something in C and go from there, anything compiled is suitable, though "compiled" is a loose definition now that LLVM exists and you can just bang out LLVM IR code instead of actual machine code. Rust started in OCaml and is now "self-hosted" on top of LLVM, for example.

i have a powershell script that automatically download from outlook and save in the file i already set. the script works fine but then i realise that some of the attachment downloaded is corrupted. here is the script that i use.
...ANSWER
Answered 2020-Nov-06 at 03:40This is likely because you attempt to save every single attachment to the same file name on disk with the $($_.attachments).saveasfile($outpath) statement.

QUESTION
I'm brand new to writing apex and especially test classes in apex. I can’t seem to find out how to properly call my class method in my test class it seems like. My test class is definitely not finished but I'm just starting with one of my delete methods.
I seem to be getting stuck on line 17 on my test class “CreateQuoteProducts_OtherOpp.DeleteQuoteProductsOTFOther(testQPOTF.id);” I’m getting an error that states:
Method does not exist or incorrect signature: void DeleteQuoteProductsOTFOther(Id) from the type CreateQuoteProducts_OtherOpp
I think I just need to pass in the OrderId but I’m not too sure what I’m doing wrong.
This is my apex class
...ANSWER
Answered 2020-Sep-10 at 21:24public static void DeleteQuoteProductsOTFOther(List OrderId) accepts list of Ids. You try to pass a single Id: CreateQuoteProducts_OtherOpp.DeleteQuoteProductsOTFOther(testQPOTF.id);
It's like "array of integers" and "one integer" are not compatible types. If you will not need that list for anything else you can create it in-flight and it'll be then discarded when that line of code finishes:
CreateQuoteProducts_OtherOpp.DeleteQuoteProductsOTFOther(new List{testQPOTF.id});
This should compile fine
QUESTION
I'm pretty new to writing Apex but everything does seem to be running smoothly separately in an executable window when I split apart the class I created below, but when I'm running this from within a flow it doesn't seem to create the records at all. The methods that delete records seem to be working, but neither of the methods to create the records is working it seems.
Any help or guidance is much appreciated!
...ANSWER
Answered 2020-Sep-11 at 19:16As specified in documentation (developer.salesforce.com/docs/atlas.en-us.apexcode.meta/…), there can be only 1 InvocableMethod by class. This means that your flow only call the first delete method, not the others. If you need to call each method, then you need to do a class for each. Maybe a screenshot of the flow might help. – Bartheleway

+DMR DCC=4
Slot 1 TG=9003 RID=69
The last 2 lines is what I am interested in getting which in the above example would be
+DMR DCC=4
Slot 1 TG=9003 RID=69
This is what I have so far which seems to work but I just feel its a bit messy and was wondering if anyone had any other suggestions.
ANSWER
Answered 2020-Aug-12 at 14:42You say that you want the last two lines but the code you have indicates that you want the last four lines. Regardless, set lineCount to the appropriate value in the code below.
QUESTION
In the "Introduction" section of K&R C (2E) there is this paragraph:
C, like any other language, has its blemishes. Some of the operators have the wrong precedence; ...
Which operators are these? How are their precedence wrong?
Is this one of these cases?
...ANSWER
Answered 2019-Feb-17 at 17:26It depends which precedence convention is considered "correct". There's no law of physics (or of the land) requiring precedence to be a certain way; it's evolved through practice over time.
In mathematics, operator precedence is usually taken as "BODMAS" (Brackets, Order, Division, Multiplication, Addition, Subtraction). Brackets come first and Subtraction comes last.Ordering Mathematical Operations | BODMAS Order of operations
Operator precedence in programming requires more rules as there are more operators, but you can distil out how it compares to BODMAS.
The ANSI C precedence scheme is pictured here:
As you can see, Unary Addition and Subtraction are at level 2 - ABOVE Multiplication and Division in level 3. This can be confusing to a mathematician on a superficial reading, as can precedence around suffix/postfix increment and decrement.
To that extent, it is ALWAYS worth considering adding brackets in your mathematical code - even where syntactically unnecessary - to make sure to a HUMAN reader that your intention is clear. You lose nothing by doing it (although you might get flamed a bit by an uptight code reviewer, in which you can flame back about coding risk management). You might lose readability, but intention is always more important when debugging.
And yes, the link you provide is a good example. Countless expensive production errors have resulted from this.
QUESTION
I've created a DMR Topic model (via Java API) which calculates the topic distribution based on the publication-year of the documents.
The resulting distribution is a bit confusing, because there are a lot of negative propabilities. Sometimes all propabilities for a whole topic are negative values. See:
Q1: Why are there negative values? The lowest possible possibility for a topic distribution for a given feature should be at least 0,0 ... I guess?
Additional I build a LDA model where the ModelLogLikelihood seems to be surreal. I trained the model with nearly 4 million documents and 20 topics. Alpha =1.0 ; Beta = 0.01 ; # iterations 1000;
Results in Model-Log likelihood: -8.895651309362761E8
Q2: Can this value be correct? Or am I doing something wrong?
...ANSWER
Answered 2020-Mar-14 at 18:55Thanks for using DMR! LDA assumes that the prior for the topic distribution for each document is a Dirichlet distribution. The parameters for a K-dimensional Dirichlet are K non-negative real numbers. DMR-LDA generates a document-specific prior based on the properties of a document.
Q1: These are not probabilities, they are regression coefficients. If you have a document with feature 2014, the value for the Dirichlet parameter for topic 1 with the expression exp(-4.5 + -0.25). This is the default parameter plus the offset for 2014, exponentiated to make it non-negative. These values are equivalent to about 0.01 for the default value with no additional features, and 0.008 (78%) for 2014.
Q2: This is a common confusion! The key is that this is a log probability. The log function crosses 0 at 1, since anything to the 0 is 1. The log of any value less than 1 is negative. Since all probabilities are less than or equal to one, all log probabilities are zero or negative. The other thing that often surprises people is how large the log probabilities are. Let's say you have a language model where each word token is independent, and the probability of a given word is usually around 1/1000. The log probability of one word is therefore around -7.0. The joint probability of a whole collection is the product of the token probabilities, so the log of that joint probability is the sum of -7. I'm guessing your collection has about 100M tokens?
