RemoteBrick – The First Java Library for the Original LEGO® SPIKE™ Prime / Robot Inventor Hub (51515)
Because there was simply no Java library that could control the original LEGO® Education Inventor Hub (51515) with its factory firmware, I built RemoteBrick completely from scratch.
Now you can finally write real Java programs for SPIKE™ Prime and Robot Inventor – no flashing, no Pybricks, no workarounds needed.
RemoteBrick communicates directly with the hub via Bluetooth Classic (SPP) and gives you 100 % of the features the official LEGO app has – just in pure Java.
Current Features in v1.3.0:
Motors (speed, degrees, tank drive, ramping, absolute position)
5×5 Display (text, images, animations, single pixels, rotation)
All sensors (color, distance, force, gyro/tilt)
Sound & tones
Hub buttons (press/release/duration)
Knock detection, battery level, hub orientation
Broadcast messages between Hubs (send/receive)
Real-time events & multi-hub support
Thread-safe API with blocking and asynchronous commands
I had the same issue until I changed my default browser to Chrome. I don't know if this is a universal fix, but if you already meet the requirements in the FAQ and nothing else has worked, maybe try this.
Looks like a lot more people are trying to download this. Since they've released similar tools like Jules earlier, those were not really clubbed with major model releases like Gemini 3.0. This time they've clubbed the 2, so they seem to have received a lot more traffic than expected.
It should be fixed in a few hours when the traffic decreases.
var hasValue = Application.Current.Resources
.TryGetValue("Primary01", out object primaryColorObj);
if (hasValue && primaryColorObj is Color primaryColor)
rtn = primaryColor;
else
rtn = Color.FromHex("#173880");
Same exact issue, saw in documentation it needs to be a personal account, so an account with a non workspace but I used my personal as well and still stuck
My code and everything was 100% the issue was in the iOS 26
iOS 26 has issues with notifications sounds and had to restart the real phone and push it into ringing mode and silent mode in order for the notifications sounds to work correctly.
i realized that after i tested the app on iPhone with iOS 17.4 and the sounds worked immediately.
I had the exact same problem and finally figured out what I was doing wrong. The requests module references the urllib3 module which references the ssl module. I had a file in my project called ssl.py and so the import ssl directive was picking up my file instead of the module; hence, the missing methods error.

mult.x = "first", # in case there are overlapping care spells (we don't want multiple "hits")
indicate = TRUE) # 3L if match, 1L if not
ans[, in_care := .join==3L]
I was trying to avoid having to edit my specifications to store the Id in a property but that does indeed work. However, the API for the Ardalis library might have changed since there is no Criteria property in the spec object. It does have a WhereExpressions collection with one entry but nowhere in there do I find a textual representation of my Guid.

Thanks for reporting this issue. It was introduced in the recent release (1.4.65) of the library. It has now been fixed in the latest version, i.e. 1.4.66
Maybe make the keyframes animation have an end (100%) that does not change how it initially was but no start (0%) at all so that it can start off from anywhere?
I've played with this question a bit and the answer is definitely yes for CRC-32-###. Which does not require brute force methods. So, you can make a fast self refencing string, if you know the magic incantations and a few tricks.
the cRC of THiS StRinG IS OBviouslY 0XBEefc0de.
If the trick isn't obvious here you can toggle case to adjust the CRC of a string, without changing the meaning.
But of course, you need to know which bits need to be toggled. And here linear algebra is your friend. because CRC is linear... it means at least for this problem. If you toggle a bit in the string the output crc will have a set of toggles associated with that toggle. So once you have 32 things you can toggle you can make a 32x32 matrix and solve for a set of toggles which have the properties you want.
thE aNsWEr To LIFE thE UNIVERse aNd eVERYthing is actually 0x42!
I used a simple thing that just tries different combinations of caps. But it is kind of obvious? isn't it?

In my case it was waiting for the OTP/Passcode again which didn't populate correctly in the Command Center. The fix was enabling VSCode to Show the login terminal when connecting to a remote SSH host. I enabled that and found that it was waiting for a Passcode.
Set: "remote.SSH.showLoginTerminal": false to true
Using older versions of VSCode and Remote SSH Plugin helps otherwise.
Dimension Tables is a "Enum type definition". Every Dimension row is a variant of this "Enum".
E.g. a list of birds known to you.
Fact Table is the "Enum" variable holding a single value.
E.g. historical list of birds you have seen over time. Each occurrence references the bird type you've encountered.
The only difference with Enums you know is that in the code an Enum represents a fixed set of variants known beforehand.
But in case of databases those sets are not fixed and they can grow (or even shrink) over time.
Your script only looks at the first level of parts, so attachments nested deeper get skipped. By recursively traversing all parts and checking both `attachmentId` and inline `data`, you should be able to download the images correctly.
To fix it, you need to recursively walk through all parts of the message payload and handle both cases (`attachmentId` vs inline `data`).
Try this:
def save_attachments(service, msg_id, payload, save_dir="attachments"):
attachments = []
def walk_parts(parts):
for part in parts:
filename = part.get("filename")
mime_type = part.get("mimeType")
body = part.get("body", {})
if filename and (body.get("attachmentId") or body.get("data")):
if body.get("attachmentId"):
attach_id = body["attachmentId"]
attachment = service.users().messages().attachments().get(
userId="me", messageId=msg_id, id=attach_id
).execute()
data = attachment.get("data")
else:
# Inline base64 data
data = body.get("data")
if data:
file_data = base64.urlsafe_b64decode(data)
filepath = os.path.join(save_dir, filename)
with open(filepath, "wb") as f:
f.write(file_data)
attachments.append(filename)
# Recurse into nested parts
if "parts" in part:
walk_parts(part["parts"])
walk_parts(payload.get("parts", []))
return attachments

This would be a different thing, but if browsers have restrictions on it for the clear security risks, then how does software like Securly block pages? It seems that the browsers would not allow it, but it is allowed and used by many schools. How does that work?
Those messages do not indicate that JGroups is being started. It's just that the configuration parser has builtin jgroups stacks it can use if necessary. When JGroups starts you will see logs coming from GMS and other protocols.
If I had to guess, I’d call plt.show(block=False) followed by plt.pause(0) before your first measurement.
This forces the GUI backend to finalize the window and apply fullscreen, so fig.get_size_inches() is correct immediately.
fig.canvas.manager.full_screen_toggle()
plt.show(block=False)
plt.pause(0) # forces one GUI event cycle
The figure does not have its true on-screen size until the GUI event loop runs once. Fullscreen mode is only applied during that first event cycle. plt.pause(0) is the clean way to let the backend process pending events without adding delays, so the correct size is available at the first measurement.

Wait-for-completion wait for a once-off event e.g. a data structure to be initialized by another thread. They are built on top of the existing waitqueue infrastructure. The kernel documentation describing them is very good kernel.org/doc/Documentation/scheduler/completion.txt
I need to increase processing speed so that backfilling daily histories takes hours, not days or weeks.
At this time, I've taken up a suggestion to build my own URL parsing engine in Rust (using the url and publicsuffix crates) for Python. I've been successful so far. The Rust program builds successfully and I am able to import the new library into python and run it. Results looks reasonable so far. I have a bit more pipeline work to do. I'll share the results when I'm done.
Clangd treats .cu files as CUDA only, so host‑side C++ features like <format> and <chrono> aren’t recognized by default. The long‑term fix should be to tell clangd to use your GCC toolchain and enable modern C++ explicitly:
This way clangd parses host code with C++20 and finds the right headers automatically, without any silenced warnings and such. It’s future‑proof since clangd will follow your toolchain instead of hard‑coded paths.

You should be doing this in PHP as html. A CSS Grid container with Flex-Direction:row & grid-template-columns:repeat(3, 1fr) & grid-template-rows:auto will automatically take your SQL data that you format within it and arrange them 3 across breaking to a new line after each group of 3.
My solution was to return the index.html when 404 happens. It applicable to any SPA apps, not just Angular. I am using Vuejs for example.
P.S. The solution of the accepted answer didn't work for me. I mean it simply redirects to the index.hml, while I want the page to stay with the same url. For example hitting the url mysite/user/123 should show me the user details instead of redirecting to the index.html (home) page.
Unfortunately, after a ton of research and testing, when working with client smart cards the server does not and will not have access to the user smartcard certificate to utilize it to make calls from the server to the server, even on behalf of the client.
The problem cannot be resolved as a server side only solution. The client browser must make the appropriate API calls and supply the credentials to authenticate/authorize with the endpoint API.
BLUF, at this time, this is not possible using Blazor server-side application that has endpoints that require end user smart card certificate authentication.
can you provide more information about how did you created the zip file?
It seems that when your zip file is unzipped it contains additional folder which is zipfilename in your case.
You can solve this by zipping like this:
# go to your application folder
cd ruby-app-folder
# zip everything recursively and create app.zip in parent folder
zip -r ../app.zip ./*
# go back to folder where the zip is created
cd ..
Then when you deploy through "Upload application version" the application should be unzipped correctly.
Thanks for your reply, I was hoping an alternative to loading the engine multiple times.
I'm not entirely satisfied with that, as there is still a freeze when loading every game (it's inside a KeepAlive component, but it does not matter : the Engine.init() which transfers the wasm into memory (I guess) is the culprit)
EDIT: oh did you mean that I can call Engine.init() just once in a canvas and then load whatever I want in it without actually having to call init again ?
I had one recommendation from a friend that said "load the engine once, let it run and just change between scenes with an exposed api"
I find this idea pretty sexy but I can't switch all my projects to just "scenes" without being absolutely sure that it is really the solution and that it will fix my problem.
Maybe that's the solution, I'm just too lazy to think by myself and would like to know if someone has already done that way...
You said: "ALB will then send request to your instance on port 80 (HTTP)." But the instance is serving the app on port 8080. So why do I need to have 80 HTTP as the Protocol/Port for the Target Group..
I am having the same issue with the input, the partial solution I came up with is using a number for the "hours" part of the input mask, so that can be negative:
The missing part is if you want to make sure that hours take two digits, now values like -1:00 are accepted. The follow up would be padding with zeros in this section.
According to my knowledge Godot can’t reuse one WASM runtime for different PCKs, so each game has to start its own engine, which causes the short freeze. The best you can do is reduce the cost:
Preload the WASM when your SPA starts so it’s already compiled.
Keep a single iframe or canvas alive instead of re-mounting it.
Use a minimal custom web build (no threads, no 3D) and let the browser cache it.
This won’t remove the stall completely, but it keeps it about as low as Godot allows today.

It is because of how SQL CLR scalar function run. When you call a CLR for each password, SQL Server has to go from SQL engine to CLR runtime "every single row". Microsoft actually explain this per-call overhead in their "Performance of CLR Integration Architecture" documentation. But like or small operations it doesn’t really matter, but when you are running 100k iteration per call it will add up. And worse news is SQL Server also disable multithreading when a scalar user-defined function is used. This User-defined functions doc explain more about that, they just force non-parallel query plans lmao. So it doesn’t matter how many cores you got, your PBKDF2 only run on one thread, but your .NET app will use all of your threads. Kinda makes sense, In the CLR Integration Overview docs they even warn against using it for CPU-heavy stuff inside SQL since it is not made for it (CLR is supposed to be lightweight). I think running PBKDF2 100k times definitely falls in that 'too heavy' category lmao. I suppose the best fix you can do is run your hash stuff outside of SQL, do them in your .NET app then just store the result in DB, since that’s what SQL is best at, a tool meant to interact with database. If you want those inside SQL, you should use a "table-valued function". Those only run once per set of rows instead of once per row, you should read more in the CLR performance docs. Good luck!
@rzwitserloot, Not really sure if I fully understood it. I've checked both of your snippets calling the `read()` method (the ones with FileReader and with BufferedReader) with a text file which has a size of around 160MB. The time difference in completing both of these operation is only of +-0.5s.
Sounds like Arduino’s servers are having a bad day. A 500 error usually means something broke on their end, not yours. You can try a couple of quick checks:
Refresh or try again after a little while.
Restart the IDE just in case.
If you need a library urgently, grab it directly from GitHub and install it manually.
If others are reporting the same thing, then it’s definitely a temporary server issue. It should clear up once Arduino fixes it.
It can be globally error also due to cloudflare outrage.
So I tell the program when it's ready to start over, so I can call (guess-my-number) only if I want a new game. I also used setf as those variables where already defined. It didn't even occur to me that I could use defparameter again.
Usually I am anti cloud but I at this bulk and if you need it relatively fast. The best option is to use a cloud hosting provider to deploy 10-100 instances of the conversion program, then split the dataset evenly across each of the instances to convert it.
I would suggest that you don't stress too much about the runtime duration over leetcode when coding in python as python is an interpreted language and its runtime is also affected by the global python interpretor used by leetcode.
From what I have noticed, leetcode compensates for this by providing larger windows for harder problems before throwing a TLE. And so, for harder problems with larger test case sizes, time complexity matters much more.
Issue is on the Microsoft Live side, they are putting too much information in the request header based upon all the different tenants you're using. This eventually creates an issue where it exceeds the allowable length of the header & causes the 400.
You can confirm this by using an Incognito/In Private window or logging in from a different browser.
Best way to workaround the issue is to clear your browser cookies & cache.
The code in your post looks like Java 6 code. Can you post a link to the webpage containing that code? Note that Oracle's Java tutorials stopped being updated since Java 8. Nonetheless, I believe that, at least, the code would use "try-with-resources".
I am using the KubernetesExecutor to run PythonOperators in Kubernetes Pods. I was able to override the namespace of each Pod dynamically in the function pod_mutation_hook in airflow_local_settings.py. However, the scheduler would stop queuing new task instances as soon as the limit of AIRFLOW__CORE__PARALLELISM was reached, even if all Pods where in status Completed. The scheduler would still report DEBUG - 120 running task instances for executor KubernetesExecutor. I assume this is, because the KubeJobWatcher does only look at one namespace. I don't know, if the KubeJobWatcher can be configured to watch multiple namespaces.
I had the same problem and I checked the password and user everywhere - they were equal. The computer name also. And the problem was in the buttun "can login" in user's Previleges - it had to bу in "on" possition. And after I turn it on, the advice do the command with the flag: "python -Xutf8 manage.py makemigrations", "python -Xutf8 manage.py migrate"
yea cloudflare is down, you can use alternatives like ollama locally and it wont break when some cloud provider goes down. its only as good as your hardware though.
SQLite3 doesn't have stored procedures that run in the RDMS but to @Dan's point of avoiding SQL injection it does prepare statements, and it supports binding values to those prepared statements.
Thanks, the times I mentioned were the submission results from leetcode, so I can't be sure as to what the input sizes were, although its to be noted that with a large input size in one of the testcases, the O(n) time solution struggled to complete in the required time, unless you loop through the set instead of the input array, and my O(nlogn) (presumably) time solution didn't struggle with it at all.
I'm quite new to this so I'm trying to figure out any rules to keep in mind when estimating the performance of my programs.
the thing about python and how to install it, it's one of the rare exceptions reading the manual labelled something akin to 'how to install' before you click yes makes sense, after i brew installed python a whole slew of issues arose so i learnt my lesson.
If you’re experiencing this problem, don’t worry — it’s usually caused by one of a few simple mistakes. Below, I’ll explain the reasons and show you the best way to fix your GridView so it scrolls smoothly and displays perfectly on all devices.
Why Your GridView Is Breaking
GridView typically breaks due to:
1. Using GridView inside a SingleChildScrollView
This causes layout conflict because both try to control the scrolling.
2. Missing item aspect ratio
Without aspect ratio, Flutter doesn’t know how much vertical space each grid item needs.
3. Using unbounded height
Widgets like Column or Expanded wrapped incorrectly will cause GridView to overflow.
In IAM, the cloud run service account should have the "Service Account Token Creator" permission to generate a signed link. You should check your permissions to allow all the ones needed
Why do you think you need the enterprise licensed version of Saxon, and not the open source HE version to execute the Schematron XSLT and perform validation?
In your implementation the commented line is in fact not crucial to sort the array. The thing is, by using swap() your'e doing something more similar to bubble sort - moving curr left until it matches the sorted part. The "actual" insertion sort would instead push all elements right and add curr to the empty space left at pre+1:
// a std::vector<int>& is also a good option - thx comments
void insertionSort(int* arr, int n) {
for (int i = 1; i < n; i++) {
int curr = arr[i];
int pre = i - 1;
while (pre >= 0 && arr[pre] > curr) {
arr[pre+1] = arr[pre];
pre--;
}
arr[pre+1] = curr; // now it's important
}
}
I think this approach is better than swapping because of the reduction of assignments per element sorted - swap() uses a temp variable.
I compared the old execute() function (system/database/drivers/odbc/odbc_driver.php) with the updated version and found the culprit. $this->is_write_type($sql) OR $success = $this->odbc_result; returns a boolean for all writes to the db. In the old version they just returned whatever odbc_exec() gave. To fix this, I just removed the first part of $this->is_write_type($sql) OR $success = $this->odbc_result; and only kept $success = $this->odbc_result;. This may cause problems if some other code expects a boolean and make a strict check for === true.
I hope this made any sense. If someone has a better solution, please tell me.
