QUESTION
I have written following code to get the daily maximum of a certain value with GORM.
- I pass the current time and get the day's start and end.
- I select all values between the day's start and end.
- I order the temperatures and get the first.
My Code:

Answered 2022-Apr-11 at 10:54You could use the max operation in SQL. Maybe not a more 'GORM' way to do this, but in my opinion a more semantically correct/appealing version:
QUESTION
For a project I'm working on, I require a function which copies the contents of a rectangular image into another via its pixel buffers. The function needs to account for edge collisions on the destination image as the two images are rarely going to be the same size.
I'm looking for tips on the most optimal way to do this, as the function I'm using can copy a 720x480 image into a 1920x955 image in just under 1.5ms. That's fine on its own, but hardly optimal.
...ANSWER
Answered 2022-Apr-10 at 19:29You can determine once for all which rectangle of the source image will effectively be copied to the destination. Then the most efficient way is to copy row by row, as the rows are contiguous. And memcpy is the fastest way.

QUESTION
I have an Excel macro code to extract unique mutations from GISAID metadata that involves:
- Trimming the "(" in the very beginning and the ")" in the very end of each value and auto-filling the trim formula down until the last row.
- Pasting (values only the trimmed data into a new sheet) and splitting the comma-delimited values.
- Stacking all the multi-columned rows into one column.
- Deleting all blank cells and shifting the subsequent cells up (if any blank cells are present).
- Removing duplicates.
This is the code that I've managed to build (I'm really really new in VBA, I've only started automating Excel processes because I'm working with GISAID data almost every day.) Users can paste the data from GISAID's .tsv metadata to A1 and just run the macro.

QUESTION
I am trying to remove horizontal lines from my daughter's drawings, but can't get it quite right.
The approach I am following is creating a mask with horizontal lines (https://stackoverflow.com/a/57410471/1873521) and then removing that mask from the original (https://docs.opencv.org/3.3.1/df/d3d/tutorial_py_inpainting.html).
As you can see in the pics below, this only partially removes the horizontal lines, and also creates a few distortions, as some of the original drawing horizontal-ish lines also end up in the mask.
Any help improving this approach would be greatly appreciated!

...ANSWER
Answered 2022-Mar-13 at 13:29The term "bridging" for Swift comes from the older Cocoa frameworks concept of Toll-Free Bridging. In Objective-C, certain Foundation class types have the same underlying layout as their CoreFoundation counterpart types such that it's possible to cast between one type and another and have them work identically: you can create a CoreFoundation object in C, then pass it to Objective-C and call methods on it — or you can create a Foundation object in Objective-C, and pass that object to a function in C expecting the CoreFoundation equivalent. Toll-Free Bridging allows you to cross the "bridge" between languages/levels of abstraction, without paying a "toll" to convert between the types (since the cast is direct in memory, there's no runtime cost to converting these types).
Not all types are like this, and these types are designed specifically to behave in this way.
The concept was carried over to Swift, where certain Foundation types can be similarly "bridged" to Swift types, such as String ↔︎ NSString, Array ↔︎ NSArray, Dictionary ↔︎ NSDictionary, etc. The bridging isn't necessarily always "toll-free" (as in, the objects can be cast directly in memory without their underlying representation being changed), but close enough.
The statement, then, saying
The value of the condition must be of type
Boolor a type bridged toBool.
means that the condition must be a Bool, or a type which can be converted directly into a Bool in this way.
The tricky thing about this description is that there isn't a type which can be unconditionally bridged into a Bool from Objective-C anymore. You can bridge an NSNumber to a Bool with a conditional cast (e.g. let b = NSNumber(value: true) as? Bool), but that's not enough to allow you to substitute an NSNumber in place of the condition:

QUESTION
I need to develop an ontology in computational biochemistry and molecular dynamics. For this, I have collected the terms that is going to be used and attempted to reuse ontologies by searching the terms on ontology search service, such as EBI-OLS. Some terms are very relevant to import/reuse, however, the ontology itself is intended for a more specific domain, such as National Cancer Institute Thesaurus (which has 171,081 classes). Other than that, there are other 10 source ontologies that I could potentially reuse. Some of them are also huge, such as EDAM ontology.
Is it okay to reuse ontology that seemingly intended for a more specific domain, such as cancer? We will use the ontology for a more generic use in life science, not only cancer-related domain.
Is there any general rule of thumb on which of those 10-ish ontologies that are suitable for reuse? (e.g., the paper describing that ontology should be cited by at least n number of papers, or it should be compatible with Open Biological and Biomedical Ontology (OBO) Foundry principles, or it should be backed by a well-known institution and still maintained).
How to decide the sweet spot on the number of ontology sources one can based on? While we can reuse as much available terms as we can (from many ontology sources, especially in life science domain), there is a concern that it would make the resulting knowledge graph representation much more complex.
Thank you for your answers.

Answered 2022-Feb-02 at 16:04Answers to your questions:
I would say yes, assuming the terms that you intent to use are indeed a match for your use case. I.e., if there is a term that you are interested in using, but say its definition or the synonyms do not match your needs, then I will probably consider not using the term.
Yes, there are. I really recommend reading the paper Ten Simple Rules for Selecting a Bio-ontology and the OBO Tutorial.
Try to keep the number of ontologies you want to use as small as is sensible (that is the smallest set of ontologies that are well aligned with the needs of your use case). The reason for this is that you will want to engage with the designers of the ontologies you use to extend and amend these ontologies for your use case. The more ontologies you use, the chances are that you will need to communicate with a larger community to affect change for your use case. This may increase development times. However, using an ontology that is not well aligned with your use case will also increase communication and timelines. Thus, the reason for keeping the number of ontologies as small as is sensible.
As for your concern regarding importing large ontologies into your ontology, the way this is dealt with is to extract only the terms you are interested using ROBOT and then to import the extracted ontology into your own ontology.
In general, I will really strongly recommend reaching out to the OBO Foundry. They have developed life science related ontologies for a number of years. Working with them you are likely to avoid many of the typical problems people run into when they start designing ontologies.
I have also written up some general guidelines from my perspective wrt choosing biological ontologies here.

Install ish
To set up your environment, cd to the project and run meson build to create a build directory in build. Then cd to the build directory and run ninja. To set up a self-contained Alpine linux filesystem, download the Alpine minirootfs tarball for i386 from the Alpine website and run ./tools/fakefsify, with the minirootfs tarball as the first argument and the name of the output directory as the second argument. Then you can run things inside the Alpine filesystem with ./ish -f alpine /bin/login -f root, assuming the output directory is called alpine. If tools/fakefsify doesn't exist for you in your build directory, that might be because it couldn't find libarchive on your system (see above for ways to install it.). You can replace ish with tools/ptraceomatic to run the program in a real process and single step and compare the registers at each step. I use it for debugging. Requires 64-bit Linux 4.11 or later.
