QUESTION
So I'm looking at a Java project for my university and the code we are working with has this syntax that I have never seen before:
...ANSWER
Answered 2022-Feb-23 at 18:00That's an instance initializer.
It's effectively a block of code that is inlined into the start of constructors (*), rather than being a constructor itself.
Since this class has no explicit constructor, the compiler gives it a default constructor. Default constructors invoke super()
, so the instance initializer is inlined into it.
It's effectively the same as:

I see patchesStrategicMerge
in my kustomization.yaml file, but not getting it clearly, like whats its need or why we require that?
kustomization.yaml
...ANSWER
Answered 2022-Feb-17 at 21:57This comes in handy you inherit from some base and want to apply partial changes to said base. That way, you can have one source YAML file and perform different customizations based on it, without having to recreate the entire resource. That is one key selling point of kustomize.
The purpose of the Strategic Merge Patch
is to be able to patch rich objects partially, instead of replacing them entirely.
Imagine you have a list, of object.

QUESTION
I have a dataset of tens of thousands of dialogues / conversations between a customer and customer support. These dialogues, which could be forum posts, or long-winded email conversations, have been hand-annotated to highlight the sentence containing the customers problem. For example:
Dear agent, I am writing to you because I have a very annoying problem with my washing machine. I bought it three weeks ago and was very happy with it. However, this morning the door does not lock properly. Please help
Dear customer.... etc
The highlighted sentence would be:
However, this morning the door does not lock properly.
- What approaches can I take to model this, so that in future I can automatically extract the customers problem? The domain of the datasets are broad, but within the hardware space, so it could be appliances, gadgets, machinery etc.
- What is this type of problem called? I thought this might be called "intent recognition", but most guides seem to refer to multiclass classification. The sentence either is or isn't the customers problem. I considered analysing each sentence and performing binary classification, but I'd like to explore options that take into account the context of the rest of the conversation if possible.
- What resources are available to research how to implement this in Python (using tensorflow or pytorch)
I found a model on HuggingFace which has been pre-trained with customer dialogues, and have read the research paper, so I was considering fine-tuning this as a starting point, but I only have experience with text (multiclass/multilabel) classification when it comes to transformers.
...ANSWER
Answered 2022-Feb-07 at 10:21This type of problem where you want to extract the customer problem from the original text is called Extractive Summarization and this type of task is solved by Sequence2Sequence
models.
The main reason for this type of model being called Sequence2Sequence
is because the input and the output of this model would both be text.
I recommend you to use a transformers model called Pegasus which has been pre-trained to predict a masked text, but its main application is to be fine-tuned for text summarization (extractive or abstractive).
This Pegasus model is listed on Transformers library, which provides you with a simple but powerful way of fine-tuning transformers with custom datasets. I think this notebook will be extremely useful as guidance and for understanding how to fine-tune this Pegasus model.
QUESTION
I am in the process of writing a binary processing module for SPIR-V shaders to fix alignment issues with float4x3[6] matrices because of driver bugs. Right now i have:
- injected necessary appropriate OpTypes and OpTypePointers.
- processed the binary to change constant buffer members from float4x3[6] to vec4[18]
- injected function properly unpacking vec4[18] into float4x3[6] accepting vec4[18] as a pointer to Uniform array 18.
- created Private storage qualifier matrix unpack targets as OpVariables.(Private in SPIR-V just means invocation-level global...).
- injected preambles about composite extraction and construction to call my new function. (since from what im seeing we need to copy arguments from constant buffers to functions always, so thats what I do).
- called the function from entrypoint, for every float4x3[6] member to have ready unpacked matrices when main() starts.
- changed OpAccessChain operations that referenced given members in constant buffers and swapped them with access chains referencing my new Private targets.
But now i ran into trouble. It looks like a function in SPIR-V can either accept Private or Function storage qualifier pointers. Not both. Is there any way i can tell SPIR-V "Yeah, you can dump both of those storage classes here as arguments"?
Or do i need to rework my solution to utilize Function storage class matrix targets, and inject them and calls to unpack them every single time they are used in a new function? This seems much less elegant since there might be way more unpack operations then. And much less hassle-free, since i would have to scan every OpFunction block separately and inject OpVariables with Function storage into every block that uses the matrices.
My problem is, after all this machinery is done my targets are living as OpTypePointer of Private Storage Duration. Therefore i cannot use them in ANY SPIR-V function generated from HLSL, since they take OpTypePointers of Function duration. My unpack function is sole exception to this since i injected it directly in SPIR-V asm, byte by byte and was able to precisely tune OpFunctionParameters in header.
...ANSWER
Answered 2022-Jan-31 at 16:54This is a matter of calling conventions. Or rather, the lack of calling conventions in SPIR-V.
Higher-level languages like GLSL and HLSL have calling conventions. They explain what it means for a function to take an input parameter and how that relates to the argument being given to it.
SPIR-V doesn't have calling conventions in that sense. Or more to the point, you have to construct the calling conventions you want using SPIR-V.
Parameters in HLSL are conceptually always passed by copy. If the parameter is an input parameter, then the copy is initialized with the given argument. If the parameter is an output parameter, the data from the function is copied into the argument after calling the function.
The HLSL compiler must implement this in SPIR-V. So if a function takes a struct
input parameter, that function's input parameter must be new storage from any existing object. When a caller tries to call this function, it must create storage for that parameter. That storage will use the Function
storage qualifier, so the parameter also uses that qualifier.
SPIR-V requires that pointer types specify the storage qualifier of the objects they point to. This is important, as how the compiler goes about generating the GPU assembly which accesses the object can be different (perhaps drastically). As such, a function cannot accept a pointer that points to different storage classes; the function has to pick one.
So if your SPIR-V adjustment system sees a function call whose source data comes from something you need to adjust, then you have two options:
Create a new function which is a copy of the old one, except that it takes a
Private
pointer.Follow the calling convention by creating
Function
-local storage and copying from yourPrivate
data into it prior to calling the function (and copying back out if it is an output parameter). There's probably code to do that sitting there already, so you probably only need to change where it copies from/to.
QUESTION
I am new to Arrow and try to establish my mental model of how its effects system works; in particular, how it leverages Kotlin's suspend
system. My very vague understanding is as follows; if would be great if someone could confirm, clarify, or correct it:
Because Kotlin does not support higher-kinded types, implementing applicatives and monads as type classes is cumbersome. Instead, arrow derives its monad functionality (bind and return) for all of Arrow's monadic types from the continuation primitive offered by Kotlin's suspend mechanism. Ist this correct? In particular, short-circuiting behavior (e.g., for nullable
or either
) is somehow implemented as a delimited continuation. I did not quite get which particular feature of Kotlin's suspend machinery comes into play here.
If the above is broadly correct, I have two follow-up questions: How should I contain the scope of non-IO monadic operations? Take a simple object construction and validation example:
...ANSWER
Answered 2022-Jan-31 at 08:52I don't think I can answer everything you asked, but I'll do my best for the parts that I do know how to answer.
What is the recommended way to implement non-IO monad comprehensions in Arrow without making all functions into suspend functions? Or is this actually the way to go?
you can use nullable.eager
and either.eager
respectively for pure code. Using nullable/either
(without .eager
) allows you to call suspend functions inside. Using eager
means you can only call non-suspend functions. (not all effectual functions in kotlin are marked suspend)
Second: If in addition to non-IO monads (nullable, reader, etc.), I want to have IO - say, reading in a file and parsing it - how would i combine these two effects? Is it correct to say that there would be multiple suspend scopes corresponding to the different monads involved, and I would need to somehow nest these scopes, like I would stack monad transformers in Haskell?
You can use extension functions to emulate Reader. For example:
QUESTION
I'm trying to use machinery as a distributed task queue and would like to deploy separate workers for different groups of tasks. E.g. have a worker next to the database server running database related tasks and a number of workers on different servers running cpu/memory intensive tasks. Only the documentation isn't really clear on how one wold do this.
I initially tried running the workers without registering unwanted tasks on to them but this resulted in the worker repeatedly consuming the unregistered task and requeuing it with he following message:
...ANSWER
Answered 2022-Jan-27 at 12:22Found the solution through some trial and error.
Setting IgnoreWhenTaskNotRegistered
to true
isn't a correct solution since, unlike what I initially thought, the worker still consumes the unregistered task and then discards it instead of requeuing it.
The correct way to route tasks is to set RoutingKey
in the task's signature to the desired queue's name and use taskserver.NewCustomQueueWorker
to get a queue specific worker object instead of taskserver.NewWorker
Sending a task to a specific queue:

QUESTION
An imperative programmer for a long time, every so often I look back in on Haskell and play a little more and learn a little more.
A question arose when thinking about a possible project:
How to implement data that I explicitly want to change in a language that treats data as immutable?
A specific case is the text that is edited by a text editor. Data.Text is available but it says things like appending a character to the end of a text involves copying the entire text over. Because of things like that, I'm wondering if Data.Text is the appropriate structure to use to implement text who's purpose is to change.
Is there a generalized thinking that addresses this sort of thing?
Over the years, I've written two implementations of text machinery in C#. One used a linked list of blocks of 256 (or 512, I forget, it's been a while) characters, similar to what's described in the Sam text editor. The other is a slightly modified version of a design done by Niklaus Wirth (who got it from someone else) in the Oberon System where text is implemented by two files (one for the original text, the other for newly entered data) and a linked list of pieces that is used to assemble and edit the text. I used two .NET StringBuilders instead of files, only append to them, and the whole things performs much better that just using StringBuilders as the text itself.
Note: I have a reasonable working knowledge of laziness, strictness, tail-recursion, thunks. Fusion is less clear to me but I've read a little on it.
I have a good bit of experience with SQL so I don't have a problem with a compiler doing things I don't fully understand, but in that language I know how to conceptualize the problem better than I do in Hasell.
...ANSWER
Answered 2021-Dec-17 at 00:12The standard reference for editor implementation in Haskell is probably the Yi editor. Its author(s) wrote some papers discussing this, e.g.:
Like many text editors, Yi uses a rope as the representation of text buffers. Specifically, it’s a purely functional rope called Yi.Rope.YiString
containing chunks of Text
, defined as a specialisation of Data.FingerTree.FingerTree
, the same data structure underlying Data.Sequence.Seq
. There are further optimisations such as caching of indices into the text and batching of operations on the buffer, but the core is just a persistent tree of Unicode text chunks.
Using a persistent data structure incurs a logarithmic time cost, but makes certain features (such as cached history and incremental computation) simpler to implement correctly.
