I'm faced with the problem of printing (in console) a value without using any library. I tried to do so by means of the returning value of main function but it seems that there is not a way to show in console the return value of a function without the use of printf(). I'm looking a piece of advice so feel free to 'brainstorm'. Any idea is welcomed, hope you can help me and thank you before hand.

I am learning about text mining and rTweet and I am currently brainstorming on the easiest way to clean text obtained from tweets. I have been using the method recommended on this link to remove URLs, remove anything other than English letters or space, remove stopwords, remove extra whitespace, remove numbers, remove punctuations.

This method uses both gsub and tm_map() and I was wondering if it was possible to stream line the cleaning process using stringr to simply add them to a cleaning pipe line. I saw an answer in the site that recommended the following function but for some reason I am unable to run it.

The sun is still above the horizon. With 7:43 from Baden Austria i try to mention my titel question with some additional example. Following the Window10 environment build 19041.985 Visual Studio Community Version 4.8.04084, the predfined Keys of a Logitech Deluxe 250 Keyboard are not altered with the visual basic method

How can I get the elapsed time since the last update in a github repository. I also want to get the main language. Picture of what i mean

I want this data, to be able to use it on another website

I thought about doing it with JS, looking in the "id" and "class" tags, but i found this code on github web:

I am currently working on a C#-UWP app that needs to be able to discovery bluetooth devices (Not BLE) on the network and ones that have been previously connected to/paired.

Im sure anyone who is new to this task will have quickly found the documentation and example are of little help. I have learned more from Stackoverflow questions about peoples experimentations than from the docs and examples, but anyways.

My main question/problem is this: After setting up the device watcher to find bluetooth devices I found that I consistently get multiple additions of the same device but having a different bluetooth address (this is a device that was previously paired but not live on the network). After much investigate and brainstorming, we discovered that each device id is actually a pairing of the devices MAC address and the BT receivers MAC address.

The reason I was getting 3 device additions per 1 physical device is because I have connected to that same device with 3 different BT receiver dongles in the past. So my question is, is there anyway to make the device watcher return the device that corresponds to the currently active BT receiver dongle?

Otherwise I will need to find the currently active BT receivers MAC address and filter out the devices that do not have this, because otherwise the user will see 3 identical devices to select and only 1 of them will pass while the other 2 will fail.

While on this subject I would also like to mention that the device properties dont seem to be working. Before creating the watcher, I have a list of properties like this for example:

I have run into an interesting problem, I already have 2 working solutions however 1 of them is incredibly slow, and the other is incredibly limited. I'm trying to brainstorm ideas on how to solve this problem Efficiently while also being as flexible as possible. I was hoping someone may have some ideas on how to go about this since I'm completely stumped.

I have a name, let's say I have some strings: "A" "B" "C" "TEST" and so on.

Then I have another string let's say... "(A OR TEST) AND B NOT C" or something along that line.

Now I need to make a Function where I can feed the second string alongside one of the first, and return a Boolean.

So:

I have two tables, slots and appointment below are the tables -

I want to query from table slots and match some specific conditions from appointment table

Here is what I want to do -

I want to query the slot.* from slots table for a particular doctor_id and I want to filter out the slot ids which are already there in the appointment table on a particular date.

Here's a use case example (from the data in above pictures) -

If I input doctor_id = 1 on date = '2021-05-09' then it should give me the available slots that means it should give me information of slot_id = 3

I have brainstormed so much but I am not able to query it.

Recently I've tried to challenge myself by trying to make a quiz game, however, as expected I've stumbled upon a error already and I can't resolve it. Well, there's no errors, but it's not working as intended, any suggestions on what to modify ?

Also, I'm a very beginner to C++ (still learning), so this might seem very dumb to others since I can already assume the problem is trivial.

Here's the code:

I am looking at brainstorming my problem here, not sure if this will trigger loads of shut down or not!

Simplified: I have a system that reads an XML file and loads it into a database.

The XML has a schema with the following:
