Well, the two more or less independent components will be the GUI on one hand and the "engine" on the other hand. You could combine both in a single prorgram/code base, but
maybe it would be a good idea to split them up into independent components that could communicate through the standard CECP = chess engine communication protocol: see here for the description on the chessprogramming wiki and here for the GNU specification.
Among other advantages, you could then use a preexistent version of the other part to test, while you are developing one of the two components.
You might probably use python-chess in both parts, since it allows graphical output as well as move generation. However, I think an engine relying on the move generation of python-chess might be slow, I don't think that library is optimized in any way for fast move generation.
Also, you'd need another component as for example pygame or more specicically Tkinter or Kivy, Pygame, Pyglet, PyGObject, PyQt, PySide, wxPython, ... for adding interactivity, i.e., mainly, dealing with mouse and/or touchscreen and possibly keyboard input events.
I had a similar problem, in my case I exported useParams from react-router instead of react-router-dom. I got no errors, just empty object for params. Took me some time to figure out where the problem was.
I made an algorythm that uses the probability distribution. And while technically O(n), it is simply always slower than quick sort. That is because at low amounts of n it simply has a bigger constant multiplier and at higher n's it has the same issue as counting sort since it can't use the cache like quick sort, so each memory access becomes slower the higher a cache level it uses. That and the fact that it realistically never gets better than O(nlog(log(n))) is why it is simply not good.
arguments.callee was previously used for recursive function calls, but is now completely banned in ES5 and ES6+ hard mode for security and improved coding.
The X Plugin introduces another connection protocol (listening on port 33060) as an alternative to the mysql connections typical of port 3306. Having first discovered the existence of mysql's port 33060 using network monitoring tools, that much seemed practically self evident. So, it can be slightly frustrating to start reading documents that explain port 33060, per se, because they explain "X Plugin" as if you knew you wanted it, already. These don't explain what features would require the second protocol (i.e. "why?"). Fortunately, that is elsewhere in Mysql docs, on the page for "Document Store."
Excerpts from that page:
To use MySQL as a document store, you use the following server features:
X Plugin enables MySQL Server to communicate with clients using X Protocol, which is a prerequisite for using MySQL as a document store. X Plugin is enabled by default in MySQL Server as of MySQL 9.3. [...]
X Protocol supports both CRUD and SQL operations, authentication via SASL, allows streaming (pipelining) of commands and is extensible on the protocol and the message layer. [...]
Clients [...] using X Protocol can use X DevAPI to develop applications. X DevAPI offers a modern programming interface [...]
The issue is likely with how your frontend .war file is structured — from your jar tf output, it lacks a WEB-INF/ directory, which is required for Open Liberty to recognize it as a valid web application. Without it, Liberty defaults to its welcome page, which is why you're only seeing the logo or a 404. To fix it, create a WEB-INF/ folder, add a minimal web.xml (even empty), and repackage the WAR like this: mkdir -p webapp/WEB-INF && cp -r dist/* webapp/ && touch webapp/WEB-INF/web.xml && cd webapp && jar -cvf ../web-app.war *. Then, make sure your server.xml in Liberty sets the correct contextRoot (e.g., / or /WebApp) and that your OpenShift route points to the right service and port (usually 9080). Your backend .war looks fine, so once the frontend is structured properly, it should start displaying correctly.
I would make sure to have small validations such as file size and type. Perhaps some optimisation on the server side for images deserves sone attention. Other than that make sure you use short live urls.
That’s about all I can think of, though I’m sure there are some more things to think about here
I just want to confirm my undetstanding about what you said, does it mean usually we don't need to use sequelize migration in the beginning of development ?? like we only use it when we want to change a column name or something in the database.
I believe I've exhausted this and the only solution I can find is to use the .alertURL property to open a Safari browser and display the full alert text along with the required source attribution. Not an elegant solution but it does provide complete coverage of the weather alert(s).
That's a bit particular question: short answer is no, but you can mitigate the problem.
There is no strict way to identify a "temp" mail from a "regular" one because, in a tecnical way, both types are valid email adresses. The same apply to phone numbers.
You can, though, resort to the answer for almost every scurity related question, i.e. validate and whitelist. This approach would mitigate the problem by creating a new one: which domain do you want to be able to register in your application?
By doing so you could only accept certain domains that you trust or, you could do the opposite by denying domains that you know to be part of a disposable mail domain.
Either way it's not a definitive answer, simply because there will always be domains that you haven't whitelisted (or blacklisted) and those will occur only when a random user using that domain will approach your application (realistically speaking, you cannot manually check every domain in the internet).
To upload files larger than 5 GB to an Amazon S3 bucket using presigned URLs, the standard presigned POST method won’t work because it only supports uploads up to 5 GB. But you can multipart upload here. For each part you have generate a generate url. After uploading all parts, send a request to complete the multipart upload with the ETags of each uploaded part.
Too sad this isn't addressed yet. I also have the same issue and it's not only for SSR but also browser builds. There is this debug_node.mjs module included which from what I understand is not supposed to be on a production build. I'll probably end up creating an issue on their GitHub repo
I would do pretty much what @phd suggested in the comments.
Instead of trying to install directly on your production machine, you can download and build everything on your build machine, then move the ready files over. Here’s how:
On your build machine, use pip to download the package and all its dependencies:
I had the same issues. I am using VS Code and when I put my cursor over the kivy word and selected quick fix, all I need to do was select the latest interpreted, which was 3.12.0.
You have done nothing wrong here.
The example you used as source is meant to be run directly in the console, not in a script (and it would be better if it mentioned that).
The issue is this:
I have this code at the start of a long script
When you check the actual description of the $Transcript variable, you'll find the following:
$Transcript
[...] If you don't specify a value for the Path parameter, Start-Transcript uses the path in the value of the $Transcript global variable. [...]
The $Transcript variable in your script is (by default) defined in the Scriptscope, not the Global scope, so Start-Transcript won't use it and fall back to the default path.
Defining $Transcript as global variable will work:
React actually handles controlled inputs with states pretty well, it does not need to have any workarounds usually. Only if the state forces the whole component to re-render somehow, then you would need a workaround.
The developer console is actually the reason why controlled inputs lag, close it and see if that helps.

Thanks for all answers, but I decided to use `from numpy.lib.recfunctions import structured_to_unstructured as str2unstr` since it might be a more direct and clear way of getting the same result.
I note latest version of exdxf is 1.4.2 from May 2025 and i still have problems with the mesh having no vertices. When might there be a version that contains the mesh entities? Many thanks, N.
After running into this issue multiple times, the best workflow to circumvent the actual problem is just using my text editor of choice and opening the crontabs' full path:
For me, it was caused by the newest version of React Router DOM i.e v7 (7.6.3), spent >2 hour figuring it out. For now i have just downgraded to the latest version of 6 (6.30.1) and my website is back to normal.
From what I can tell, the <varname>:<classname> syntax is a purely cosmetic syntax used to give type hints for future programmers and for your linter/code editor so that it can give you useful type information. Note that since python is dynamically typed, putting type hint after a variable does not guarantee that the variable is of that type, just that you expect it do be. It is generally good practice for production code to include these type hints if the type of a variable is not obvious or implied by some other part of the code. Essentially, it is a fancy comment. Hope this helps!
I think the problem is in your flutter path, you installed flutter in the system root. try installing flutter in C:\Users\{username}, I think this will solve the problem.
Does this problem still exits? , because in the recent update or transformation of idx to firebase studio they have rectified this issue, if it still exists there is hard restart the device option on top left corner on the emulator tab so you could do that for a total restart device that restarts it and shows the debug mode app preview, There is other not common work around you could setup flutter project in Android Studio cloud Hope you got the solution for your problem.
The best place to trigger the API call to fetch full train details would be Screen B's ViewModel. You can have a common repository class for defining the calls and all, then you can inject the same into both the ViewModels (of Screen A and Screen B). Thereafter, just let the ViewModel change its own state (by relying on the concerned functions from the repository) and you will be good to go. The navigation flow will surely not be the right place to do the API call because that way you are violating the Single Responsibility Principle.
You're likely running into issues because the forum's search page uses dynamic content loading or server-side protections that make scraping more complex.
A few things to try:
Check if the content is loaded via JavaScript – If so, Scrapy alone won’t see it. You might need to use Splash (for rendering JS in Scrapy) or tools like Playwright/Selenium instead.
Session or headers required – The server may require specific headers (like Referer, User-Agent, Cookies, etc.) to return results. Use browser dev tools (F12) > Network tab to inspect what's being sent during a normal search and replicate those headers in your Scrapy request.
Rate-limiting or bot detection – Frequent or unauthenticated requests can trigger temporary bans or timeouts. Try slowing down your crawl (using DOWNLOAD_DELAY, AUTOTHROTTLE_ENABLED) and setting realistic headers.
Try using a real browser to inspect redirects or session IDs – It’s possible your first search loads a temporary session or token you need to persist.
Let us know what you find in the response headers or logs — happy to dig deeper!
I have encounter the same problem and spent 2 days solving this error. For me the problem was the environment setup, I have work on other projects and I have installed jdk 24 which react native does not support.. I followed the docs, downgrade jdk to v17 and its working fine now. Click here - https://reactnative.dev/docs/set-up-your-environment
You could use an range input. Then you could simply add an event listener on the video for "timeupdate" and an event listener of the range for "input" to sync them.
Hi after reviewing the source code I found an implementation of the request method as follows:
@abstractmethod
def request(self, method, url, headers=None, raise_exception=True, **kwargs):
"""Main method for routing HTTP requests to the configured Vault base_uri. Intended to be implement by subclasses.
:param method: HTTP method to use with the request. E.g., GET, POST, etc.
:type method: str
:param url: Partial URL path to send the request to. This will be joined to the end of the instance's base_uri
attribute.
:type url: str | unicode
:param headers: Additional headers to include with the request.
:type headers: dict
:param kwargs: Additional keyword arguments to include in the requests call.
:type kwargs: dict
:param raise_exception: If True, raise an exception via utils.raise_for_error(). Set this parameter to False to
bypass this functionality.
:type raise_exception: bool
:return: The response of the request.
:rtype: requests.Response
"""
raise NotImplementedError
I am new at python but it seems like the class isn't already implemented, instead it is just raising an error, then this is why the call is working by curl but not by py
Thanks all for your help, I really appreciate your time.
Just discard time, no need to calculate timestamp:
let now = new Date();
let startOfToday = new Date(now.getFullYear(), now.getMonth(), now.getDate());
let startOfYesterday = new Date(now.getFullYear(), now.getMonth(), now.getDate()-1);
I’ve been through the same solo-dev slump while working on a long-term project. What helped me wasn’t motivation tricks, but having a structured vault to organize my thinking — feature ideas, scope changes, “half-baked” experiments, and even commit prep all in markdown.
NS-3 uses the SSID string as part of its internal hashing mechanism to seed random number generators for various network operations. When you change the SSID from "ns3-80211n" to "abc", you're inadvertently changing the seed values for:
For me, the issue was that the AI auto-completed the necessary version number for me. It put version 1.6.2 for the rules and runner APIs. Version 1.6.2 doesn't exist.
There's links provided in the feedback generated that say where it tried to go to download the versions. One of them is on Google and the other from Maven. If you search for the information on Maven's website, you can see valid version numbers (including some experimental versions).
I switched to 1.6.1 (a valid version), resynced the build.gradle file, and then tried again. That fixed my issue.
Fwiw I was able to both simplify the approach, improve the performance and refine the behaviour (thanks to Matt for getting me on the right track). Here's the full code in case it helps anybody else.
I had this same issue. I was loading the bootstrap.bundle.js file in the body element as the last item, but moving it to the head element solved it for me.
After finding an issue on their GitHub with the same problem I was able to solve the problem by depending on the `okhttp-jvm` dependency instead, as Maven doesn't seem to have the same "awareness" for module metadata as Gradle does.
So, if you're using Maven and get the same issue, try changing the okhttp artifact ID to okhttp-jvm.
Running CodeBuild inside a private subnet within a vpc, and giving it outbound internet access:
We have to attach NAT gateways to private subnets we wish to give outbound internet access.
In a vpc configuration, a subnet is public if it is attached to an internet gateway (igw for short). And we do this using a subnet association in a route table: we can use the default route table that comes with the vpc; we add the route [destination: 0.0.0.0/0, target: igw-XXXX where igw-XXXX is an igw], we then move to the route table subnet association and attach the subnet we wish to make public. Of course, you can create the igw if you haven't.
Once this subnet is made public, we have to create the NAT gateway we wish to attach to private subnets, within this public subnet. So, when creating the NAT, in the form for creating the NAT, we must select this public subnet as its subnet.
Now let's move over to the private subnets. We must ensure these private subnets are not associated with our default route table since we're using this route table to route traffic to the igw. If they are, they are automatically public subnets.
We must create a new route table to manage routing for our private subnets. Now create the new route table, and select our vpc while doing that. After that, add a route to this table [destination: 0.0.0.0/0, target: nat-XXXX where nat-XXXX is the NAT you created]. Next, we move to the route table subnet association and attach all the subnets we wish to make private.
Now since this NAT's subnet (the subnet selected while creating the NAT) is a public subnet and attached to an igw, all the private subnets associated with this NAT, would have outbound internet traffic.

This visualization, made with invocation_tree, shows how mergesort([3,2,7,1,4,6,5]) repeatedly splits the problem into sub-problems until a sub-problem is sorted, and then recombines the result of two sorted sub-problems using merge() before it returns:
This is the final result as a static image for your viewing pleasure:
I had this same problem. I was using axis inside a tikzpicture which was inside a node from a tikzpicture (so my axis was in a 'nested' tikzpicture). The node had [anchor = north] . Removing this anchor fixed the issue.
What were you using OpenTSDB for? Bigtable now supports a lot of time series capabilities out of the box e.g. there are
distributed counters for fast write time aggregations (sum/count, min/max, approximate count distinct) which you can also do for tumbling windows using date truncation on timestamps
continuous materialized views allow you to define more complex, multi-row aggregation logic using SQL that get automatically and incrementally updated as new writes come. You can also re-key your data using these views for secondary access patterns like building a secondary index
As part of Bigtable's SQL support you can also do read-time aggregations on top of the pre-aggregated data e.g. if you preaggregate to hourly using counters or incremental materialized views, you can filter/group to daily, weekly etc. at read time using a GROUP BY at read time including merging data sketches e.g. from daily active users to monthly active users etc.
These are most common operations in time series databases and doing directly in the database would simplify your stack instead of running an additional service on top of it in GKE.
If a Service declared in your app's manifest is running then your app is running. One of the purposes of Services is to be alive independent of any Activity that can be visible on the screen.
Regarding "binding" Services... this term usually stands for using a ServiceConnection to bind a Service to an Activity, so I'm unclear what you mean by "My app has a bound service". Bound to what? Have you done any binding?
It seems that you're trying to access a Service defined in App1 from App2. I don't believe this is possible. Perhaps if you described to us your goal we could point you towards a path to implementation.
My plan is to create an Accounting System for small charities using the python language, tkinter and sqlite. I have used gnucash in my own charity: beesanctuarymovement.org and wish to create my own program with features not present in gnucash such as creating a receipts and payments account report, and a statement of assets and liabilities as described in the charity treasurer's handbook. Small charities do not buy or sell on credit; so there is no need for a sales and purchase ledger. They do however need bank/cash transactions to be subdivided by fund.
If you are familiar with gnucash split entry transactions, that is the feature I wish to copy. There is a one to many relationship between journal table which contains information specific to every transaction; and the ledger which has a foreign key Tran_id which refers to the journal.
I wish to create a form which joins the Journal and Ledger tables. The sum of all amounts in the ledger table for all lines which share tran_id should add up to zero ( or equivalently in accounting jargon all credits equal all debits.
My plan is this form (or grid) should display all ledger rows (joined with journal info) for a specific account_id. Clicking on any row in this table should allow you to edit the full transaction in situ.
Sorry if you don't understand the gist of this. It is very hard to explain bookkeeping in an understandable way given the current constraints. The form (grid) should display a running balance of the specified account, and this is not stored in the sql tables, instead it will be calculated by panda and displayed in the sheet.
I have done a lot of research, and I believe combining panda and tksheet is the best way to do what I want.
I think it would be better to compare LISP to the Peano Postulates than to Euclidean Geometry.
I have constructed a complete Peano Natural Number Arithmetic in LISP, and can see a clear path to creating the Rational Arithmetic. A Natural corresponds to a List of Units, i.e. Unary Numerals. Cons corresponds to the Successor operation; An Integer is a pair of Naturals, the Difference between the two; a Rational is a pair of Integers, the Ratio of the Two. Rational arithmetic is closed under addition, subtraction, multiplication, and division, except division by zero. Addition and Multiplication are recursively defined as in Peano. The sums and products of Rationals are the standard definitions. Subtraction: change sign (reverse order of the pair of naturals) and Add; Division: invert (reverse order as in add) and Multiply.
