You should use cache.asMap().remove(key) as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.

The Cache interface is opinionated for how one should commonly use a cache, while the asMap() view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.

maven multi-module project with two versions of protobuf

Asked 2021-Jun-15 at 21:40

We have a multi-module maven project. One of the modules has a bunch of .proto files, which we compile to java files. Pretty much every other module depends on this module. Most of them use Protobuf 2.4, but one needs to use 2.5.

Is there any nice way to do this? (The not nice way is to edit the pom file to say "2.5", build a jar, manually copy that jar to wherever we need it, and then change the pom file back to 2.4.)

...

ANSWER

Answered 2021-Jun-08 at 13:59

Never used protobuf, but, as I understand it's a plugin that generate stuff.

So I'm gonna give you generic pointer hoping it will help. I think you should either try to make 2 jar with different classifier from a single module, see https://maven.apache.org/plugins/maven-jar-plugin/examples/attached-jar.html For example classifier proto2.4 and proto2.5 then you can add the classifier when you define the dependency to that module.

Other option I see is having 2 modules, the real one, you have now, and another one for 2.5 Generate a zip from the main one and the second module would be empty but have a dependency on the generated zip, unzip it and then compile with the plugin config for 2.5 Slower at execution, a bit dirtier imho, but can be needed if for example you need more customization than just the version.

My research of the major syntax and functionality differences from http://www.greenend.org.uk/rjk/tech/regexp.html:

. in GNU grep does not match null bytes and newlines (but does match newlines when used with --null-data), while Perl, everything except \n is matched.
[...] in GNU grep defines POSIX bracket expressions, while Perl uses "character" classes. I'm not sure on the details. See http://www.greenend.org.uk/rjk/tech/regexp.html#bracketexpression
"In basic regular expressions the meta-characters ?, +, {, |, (, and ) lose their special meaning; instead use the backslashed versions \?, \+, \{, \|, $, and $." From https://www.gnu.org/software/grep/manual/html_node/Basic-vs-Extended.html. ERE matches PCRE syntax.
GNU grep \w and \W are the same as [[:alnum:]] and [^[:alnum]], while Perl uses alphanumeric and underscore.
GNU grep has \< and \> for start and end of word.

Perl supports much more additional functionality:

"nongreedy {}" with syntax re{...}?
additional anchors and character types \A, \C, \d, \D, \G, \p, \P, \s, \S, \X. \Z, \z.

QUESTION

Using std::atomic with futex system call

Asked 2021-Jun-15 at 20:48

In C++20, we got the capability to sleep on atomic variables, waiting for their value to change. We do so by using the std::atomic::wait method.

Unfortunately, while wait has been standardized, wait_for and wait_until are not. Meaning that we cannot sleep on an atomic variable with a timeout.

Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.

Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic to WaitOnAddress on Windows and it will (kinda) work with no UB, as the function gets void* as a parameter, and it's valid to cast std::atomic to void*

On Linux, it is unclear whether it's ok to mix std::atomic with futex. futex gets either a uint32_t* or a int32_t* (depending which manual you read), and casting std::atomic to u/int* is UB. On the other hand, the manual says

The uaddr argument points to the futex word. On all platforms, futexes are four-byte integers that must be aligned on a four- byte boundary. The operation to perform on the futex is specified in the futex_op argument; val is a value whose meaning and purpose depends on futex_op.

Hinting that alignas(4) std::atomic should work, and it doesn't matter which integer type is it is as long as the type has the size of 4 bytes and the alignment of 4.

Also, I have seen many places where this trick of combining atomics and futexes is implemented, including boost and TBB.

So what is the best way to sleep on an atomic variable with a timeout in a non UB way? Do we have to implement our own atomic class with OS primitives to achieve it correctly?

(Solutions like mixing atomics and condition variables exist, but sub-optimal)

...

ANSWER

Answered 2021-Jun-15 at 20:48

You shouldn't necessarily have to implement a full custom atomic API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic and pass it to the system.

Since std::atomic does not offer some equivalent of native_handle like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.

For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T type -- at least for integral values ^[1]. This is an assurance that will make it possible to extract out this value.

... and casting std::atomic to u/int* is UB

This isn't actually the case.

std::atomic is guaranteed by the standard to be Standard-Layout Type. One helpful but often esoteric properties of standard layout types is that it is safe to reinterpret_cast a T to a value or reference of the first sub-object (e.g. the first member of the std::atomic).

As long as we can guarantee that the std::atomic contains only the u/int as a member (or at least, as its first member), then it's completely safe to extract out the type in this manner:

General approach to parsing text with special characters from PDF using Tesseract?

I would like to extract the definitions from the book The Navajo Language: A Grammar and Colloquial Dictionary by Young and Morgan. They look like this (very blurry):

I tried running it through the Google Cloud Vision API, and got decent results, but it doesn't know what to do with these "special" letters with accent marks on them, or the curls and lines on/through them. And because of the blurryness (there are no alternative sources of the PDF), it gets a lot of them wrong. So I'm thinking of doing it from scratch in Tesseract. Note the term is bold and the definition is not bold.

How can I use Node.js and Tesseract to get basically an array of JSON objects sort of like this:

...

ANSWER

Answered 2021-Jun-15 at 20:17

Tesseract takes a lang variable that you can expand to include different languages if they're installed. I've used the UB Mannheim (https://github.com/UB-Mannheim/tesseract/wiki) installation which includes a ton of languages supported.

To get better and more accurate results, the best thing to do is to process the image before handing it to Tesseract. Set a white/black threshold so that you have black text on white background with no shading. I'm not sure how to do this in Node, but I've done it with Python's OpenCV library.

If that font doesn't get you decent results with the out of the box, then you'll want to train your own, yes. This blog post walks through the process in great detail: https://towardsdatascience.com/simple-ocr-with-tesseract-a4341e4564b6. It revolves around using the jTessBoxEditor to hand-label the objects detected in the images you're using.

Edit: In brief, the process to train your own:

Install jTessBoxEditor (https://sourceforge.net/projects/vietocr/files/jTessBoxEditor/). Requires Java Runtime installed as well.
Collect your training images. They want to be .tiffs. I found I got fairly accurate results with not a whole lot of images that had a good sample of all the characters I wanted to detect. Maybe 30/40 images. It's tedious, so you don't want to do TOO many, but need enough in order to get a good sampling.
Use jTessBoxEditor to merge all the images into a single .tiff
Create a training label file (.box)j. This is done with Tesseract itself. tesseract your_language.font.exp0.tif your_language.font.exp0 makebox
Now you can open the box file in jTessBoxEditor and you'll see how/where it detected the characters. Bounding boxes and what character it saw. The tedious part: Hand fix all the bounding boxes and characters to accurately represent what is in the images. Not joking, it's tedious. Slap some tv episodes up and just churn through it.
Train the tesseract model itself

save a file: font_properties who's content is font 0 0 0 0 0
run the following commands:

tesseract num.font.exp0.tif font_name.font.exp0 nobatch box.train

unicharset_extractor font_name.font.exp0.box

shapeclustering -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr

mftraining -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr

cntraining font_name.font.exp0.tr

You should, in there close to the end see some output that looks like this:

Master shape_table:Number of shapes = 10 max unichars = 1 number with multiple unichars = 0

That number of shapes should roughly be the number of characters present in all the image files you've provided.

If it went well, you should have 4 files created: inttemp normproto pffmtable shapetable. Rename them all with the prefix of your_language from before. So e.g. your_language.inttemp etc.

Then run:

combine_tessdata your_language

The file: your_language.traineddata is the model. Copy that into your Tesseract's data folder. On Windows, it'll be like: C:\Program Files x86\tesseract\4.0\tessdata and on Linux it's probably something like /usr/shared/tesseract/4.0/tessdata.

Then when you run Tesseract, you'll pass the lang=your_language. I found best results when I still passed an existing language as well, so like for my stuff it was still English I was grabbing, just funny fonts. So I still wanted the English as well, so I'd pass: lang=your_language+eng.

QUESTION

Coalescing multiple chunks of columns with the same suffix in names (R)

Asked 2021-Jun-15 at 20:10

I have a dataset with various "chunks" of columns with different prefixes, but the same suffix:

ID A034 B034 C034 D034 A099 B099 A123 B123 ... 1 NA 1 NA NA NA 3 1 NA ... 2 2 NA NA NA 2 NA NA 2 ... 3 NA NA 2 NA NA 2 1 NA ...

The number of columns within each "chunk" also varies. Is there any way (other than manually, which is what I have been painstakingly doing with coalesce(!!! select(., contains("XXX")))) to automatically coalesce by chunk based on the shared suffix? That is, the result should resemble

ID 034 099 123 ... 1 1 3 1 ... 2 2 2 2 ... 3 2 2 1 ...

The little lighter colored "ct" prompt is just a visual aid and it does not always show up. When you provide a raw value as an argument, it will show the prompt (like this, 1, or "foo"). When you provide a variable for the argument like ctx, foo, etc, it does not show up. This goes for all functions that take arguments.

The moral of the story is, it is not important and can be ignored.

How to get token from API with Python?

...

ANSWER

Answered 2021-Jun-12 at 17:16

First note that a token must be obtained from the server ! A token is required to make some API calls due to security concerns. There are usually at least two types of tokens:

Access token: You use it to make API calls (as in the Authorization header above). But this token usually expires after a short period of time.
Refresh token: Use this token to refresh the access token after it has expired.

You should use requests-oauthlib in addition with requests.
https://pypi.org/project/requests-oauthlib/
But first, read the available token acquisition workflows:
https://requests-oauthlib.readthedocs.io/en/latest/oauth2_workflow.html#available-workflows
and choose the right workflow that suits your purposes. (The most frequently used is Web App workflow)
Then, implement the workflow in your code to obtain the token. Once a valid token is obtained you can use it to make various API calls.

As a side note: be sure to refresh token if required.
