kandi X-RAY | EXOTIC Summary
A Python 3 package for analyzing photometric data of transiting exoplanets into lightcurves and retrieving transit epochs and planetary radii. The EXOplanet Transit Interpretation Code relies upon the transit method for exoplanet detection. This method detects exoplanets by measuring the dimming of a star as an orbiting planet transits, which is when it passes between its host star and the Earth. If we record the host star’s emitted light, known as the flux, and observe how it changes as a function of time, we should observe a small dip in the brightness when a transit event occurs. A graph of host star flux vs. time is known as a lightcurve, and it holds the key to determining how large the planet is, and how long it will be until it transits again. The objective of this pipeline is to help you reduce your images of your transiting exoplanet into a lightcurve, and fit a model to your data to extract planetary information that is crucial to increasing the efficiency of larger observational platforms, and futhering our astronomical knowledge.

QUESTION
I've written a small function with C-code and a short inline assembly statement.
Inside the inline assembly statement I need 2 "temporary" registers to load and compare some memory values.
To allow the compiler to choose "optimal temporary registers" I would like to avoid hard-coding those temp registers (and putting them into the clobber list).
Instead I decided to create 2 local variables in the surrounding C-function just for this purpose. I used "=r" to add these local variables to the output operands specification of the inline asm statement and then used them for my load/compare purposes.
These local variables are not used elsewhere in the C-function and (maybe because of this fact) the compiler decided to assign the same register to the two related output operands which makes my code unusable (comparison is always true).
Is the compiler allowed to use overlapping registers for different output operands or is this a compiler bug (I tend to rate this as a bug)?
I only found information regarding early clobbers which prevent overlapping of register for inputs and outputs... but no statement for just output operands.
A workaround is to initialize my temporary variables and to use "+r" instead of "=r" for them in the output operand specification. But in this case the compiler emits initialization instructions which I would like to avoid.
Is there any clean way to let the compiler choose optimal registers that do not overlap each other just for "internal inline assembly usage"?
Thank you very much!
P.S.: I code for some "exotic" target using a "non-GNU" compiler that supports "GNU inline assembly".
P.P.S.: I also don't understand in the example below why the compiler doesn't generate code for "int eq=0;" (e.g. 'mov d2, 0'). Maybe I totally misunderstood the "=" constraint modifier?
Totally useless and stupid example below just to illustrate (focus on) the problem:
...ANSWER
Answered 2022-Apr-12 at 04:54I think this is a bug in your compiler.
If it says it supports "GNU inline assembly" then one would expect it to follow GCC, whose manual is the closest thing there is to a formal specification. Now the GCC manual doesn't seem to explicitly say "output operands will not share registers with each other", but as o11c mentions, they do suggest using output operands for scratch registers, and that wouldn't work if they could share registers.
A workaround that might be more efficient than yours would be to follow your inline asm with a second dummy asm statement that "uses" both the outputs. Hopefully this will convince the compiler that they are potentially different values and therefore need separate registers:
QUESTION
My dead simple Excel workbook myTestBook.xlsb has a single empty table and a single code module with the routine test_openclose() inside. This routine just opens another Excel workbook (Mappe3.xlsx), then closes that workbook again.
When the routine is run (Alt-F8) with the VBA IDE closed, everything is fine.
When the routine is run (Alt-F8) with the VBA IDE opened, the intermittently opened workbooks keep getting listed in the IDE's project explorer. Each repetitive run leads to another entry in the IDE's project explorer.
Why is that and what can I do against this effect?
View after 6 runs with closed IDE (no entries) and 3 runs with IDE open (3 entries):
You can also see that the Workbook Mappe3.xlsx which is getting imported, is very simple too: just a single (empty) table, no named ranges, no internal or external references, no modules.

Been working on a project and finally got it to connect to the API and pull the data, now just just need certain information from the information pulled.
Looking at trying to get just the Quantity total for the item so I place it into a variable and then utilize the information within the script. This is how the information looks when its pull from the API.

QUESTION
Haskell typeclasses often come with laws; for instance, instances of Monoid are expected to observe that x <> mempty = mempty <> x = x.
Typeclass laws are often written with single-equals (=) rather than double-equals (==). This suggests that the notion of equality used in typeclass laws is something other than that of Eq (which makes sense, since Eq is not a superclass of Monoid)
Searching around, I was unable to find any authoritative statement on the meaning of = in typeclass laws. For instance:
- The Haskell 2010 report does not even contain the word "law" in it
- Speaking with other Haskell users, most people seem to believe that
=usually means extensional equality or substitution but is fundamentally context-dependent. Nobody provided any authoritative source for this claim. - The Haskell wiki article on monad laws states that
=is extensional, but, again, fails to provide a source, and I wasn't able to track down any way to contact the author of the relevant edit.
The question, then: Is there any authoritative source on or standard for the semantics for = in typeclass laws? If so, what is it? Additionally, are there examples where the intended meaning of = is particularly exotic?
(As a side note, treating = extensionally can get tricky. For instance, there is a Monoid (IO a) instance, but it's not really clear what extensional equality of IO values looks like.)
ANSWER
Answered 2022-Feb-24 at 22:30Typeclass laws are not part of the Haskell language, so they are not subject to the same kind of language-theoretic semantic analysis as the language itself.
Instead, these laws are typically presented as an informal mathematical notation. Most presentations do not need a more detailed mathematical exposition, so they do not provide one.

QUESTION
Summary: I got VS Code. I got empty HTML template file in which i learn how to write js scripts. VS Code has debugger, which can launch my file in Chrome for debugging (theoretically). I set up breakpoints in file.
I can make debugger launch Chrome and open HTML file, but Chrome doesn't stop on breakpoints and runs whole script.
I cant pause scripts from VS Code. Unless i pause script from Chrome dev tools manually.
Question: How to run debug in VS Code so that it would launch Chrome in debug mode with paused .js scripts on HTML page?
i mean, i really dont use something exotic like external scripts or environments or other stuff. Its just a plain HTML template file, with 5-30 lines of .js script code in it. Nothing else. I would expect something so basic would be able to work "from the box" with a push of a button. But its not.
...ANSWER
Answered 2022-Jan-03 at 22:43This is possible:
From the VSCode docs: https://code.visualstudio.com/docs/nodejs/browser-debugging
The simplest way to debug a webpage is through the Debug: Open Link command found in the Command Palette (Ctrl+Shift+P). When you run this command, you'll be prompted for a URL to open, and the debugger will be attached.
QUESTION
I'm lost.. I wanted to play around with the compiler explorer to experiment with multithreaded C code, and started with a simple piece of code. The code is compiled with -O3.
ANSWER
Answered 2021-Dec-28 at 12:48It's because of following rule:
[intro.progress]
The implementation may assume that any thread will eventually do one of the following:
- terminate,
- make a call to a library I/O function,
- perform an access through a volatile glvalue, or
- perform a synchronization operation or an atomic operation.
The compiler was able to prove that a program that enters the loop will never do any of the listed things and thus it is allowed to assume that the loop will never be entered.
QUESTION
db:Postgresql-14. This will be an infrequent transformation, and I'm looking for recommendations / improvements that can be made so I may learn/hone my postgres/json skills (and speed/optimize this very slow query).
We receive variable size/structure json objects from an external api.
Each json object is a survey response. Each nested "question/answer" object can have a quite different structure. In total there are about ~5 known structures.
Response objects are stored in a jsonb column that has a jsonb_ops gin index.
Table has about 500,000 rows. Each row's jsonb column object has about 200 nested values.
Our goal is to extract all the nested question/answer responses into another table of id,question,answer. On the destination table we'll be doing extensive querying with FTS and trigram, and are aiming for schema simplicity. That is why I'm extracting to a simple table instead of doing anything more exotic with jsonb querying. There is also a lot of metadata cruft in those objects that I don't need. So I'm also hoping to save some space by archiving the origin table (it's 5GB + indexes).
Specifically I'd love to learn a more elegant way of traversing and extracting the json to the destination table.
And I've been unable to figure out a way to cast the results to actual sql text instead of quoted jsontext (normally I'd use ->>, ::text, or the _text version of the jsonb function)
This is a very simplified version of the json object to ease just running this.
Thank you in advance!
...ANSWER
Answered 2021-Nov-24 at 19:50First idea : remplace the 4 queries with UNION by 1 unique query.
Second idea : the statement level1.value['answer'] as answer in the first query sounds like the statement jsonb_path_query(level1.value, '$.answer')::jsonb as answer in the second query. I think both queries return the same set of rows, and the duplicates are removed by the UNION between both queries.
Third idea : use the jsonb_path_query function in the FROM clause instead of the SELECT clause, using CROSS JOIN LATERAL in order to break down the jsonb data step by step :
