Modest | fast HTML renderer implemented as a pure C99 library | Parser library

When I need to hook code to the "moment a post is added or updated" in WordPress, the WordPress API provides me with save_post() hook.

Nice and easy to add an action to it, so we can perform our own custom logic whenever a post is updated or created. Simple example:

I am working on a modest SPA that (will) use Firebase for Authorization and Firestore for the DB and Flask on the backend (It's not strictly a true SPA because things like contact page, terms, etc are on different pages). I have gone through tutorials such as Firenotes doc tutorial, and it looks like because it is a JWT instead of a session I have to authenticate with every request.

Question(s):

1. Is it considered best practice to validate on every request or should I log the user in and then store a session?

2. Even if I store the user in a session, I would still need to authenticate their JWT on any database call, so there is no uplift there is there?

3. Is there any concern about cloud costs with either approach?

We have a modest clickhouse cluster, ~30 nodes, and want to collect usage stats on it. We are hoping to do this using scheduled queries against the system tables, but using a normal query only get information on the one node you happen to be connected to, and creating a distributed table only works with the *log system tables. We can loop over the nodes, but don't want to do that. Is there a way to get all the instances of a system table, such as system.parts, in one query?

I'm studying React and right now i'm using this library https://www.npmjs.com/package/react-datetime-range-picker to create a react datetime range. The problem is that now I want to remove the borders from the inputs but I don't know how to override the style provided from the library without modify the library.

While Azure Event hub can have thousands and million? of messages per second, the Azure IoT hub has a surprisingly low limitation on this.

• S1 has 12 msg/sec speed but allow 400.000 daily msg pr. unit
• S2 has 120 msg/sec speed but allow 6.000.000 daily msg pr. unit
• S3 has 6000 msg/sec speed but allow 300.000.000 daily msg pr unit.

Imagine an IoT solution where your devices normally sends 1 message every hour, but have the ability to activate a short "realtime" mode to send messages every second for about 2 minutes duration.

Example: 10.000 IoT devices:

Let's say 20% of these devices happens to start a realtime mode session simultaneously 4 times a day. (We do not have control over when those are started by individual customers). That is 2000 devices and burst speed needed is then 2000 msg/second.

Daily msg need:

• Normal messages: 10.000dev * 24hours = 240.000 msg/day
• Realtime messages daily count: 2.000dev * 120msg(2 min with 1 msg every second) * 4times a day = 960.000 messages Total daily msg count need: 240.000 + 960000 msg = 1.200.000 msg/day. Needed Azure IoT hub tier: S1 with 3 units gives 1.200.000 msg/day. ($25 * 3units = $75/month)

Burst speed needed:

• 2000 devices sending simultaneously every second for a couple of minutes a few times a day: 2000 msg/second. Needed Azure IoT hub tier: S2 with 17 units gives speed 2040 msg/second. ($250 * 17units = $4250/month) Or go for S3 with 1 unit, which gives speed 6000 msg/second. ($2500/month)

The daily message count requires only a low IoT hub tier due to the modest messages per day count, but the need for burst speed when realtime is activated requires an unproportionally very high IoT hub tier which skyrockets(33 times) the monthly costs for the solution, ruining the businesscase.

Is it possible to allow for temporary burst speeds at varying times during a day as long as the total number of daily messages sent does not surpass current tier max limit?

I understood from an article from 2016 by Nicole Berdy that the throttling on Azure IoT hub is in place to avoid DDOS attacks and misuse. However to be able to simulate realtime mode functionality with Azure IoT hub we need more Event Hub like messages/second speed. Can this be opened up by contacting support or something? Will it help if the whole solution is living inside its own protected network bubble?

Thanks,

I have text with large numbers of special characters that I want to extract certain substrings from:

I need to build a new dictionary whose values are filled conditionally. The problem I have is; I need to search over millions of items to do so. Below is my attempt to do it with a modest amount of information, but in practice, I need to do this same thing with something many hundreds times its size and it will take hours.

I want a multiline EDIT control, which is a child of a dialog, to take tabs as regular text input (instead of switching to the next control).

According to multiple resources, the correct way of doing this is to handle WM_GETDLGCODE and returning DLGC_WANTTAB (or checking + DLGC_WANTMESSAGE).

Raymond's article suggests that what I want is in fact the default behavior, which is not what I'm observing.

Reproduction:

This is based on Visual Studio's default Windows Desktop Application C++ template. If you don't have that for some reason, the contents aren't that important; what's important is that there is an "About" dialog box being shown with the DialogBox function.

Create an EDIT control in the dialog, and subclass that:

The task is to append a swarm of small circles around the nodes of a tree (where I have placed bigger circles). The depth of the tree is tiny -- just two, However, there is a slight degree of complexity when considering I'm appending several trees iteratively.

To keep it simple, I didn't even try to append swarms to all trees. Instead, I set myself with a more modest goal of appending the swarm to just one node of one tree. Comments and snippet below:
