one-on-one | A template for a weekly 1:1 repo | GraphQL library

Everything is going great, but I don't see this right and left arrors in my slide show. What should I do to fix it? I did the exactly what is in bootstrap documentation. I tried to look at on google, but couldn't find anything related to this issue. I need your help with this issue, please. (it still doesnt upload my post, so filling the blanks)

I only can see the tab which is I made active by default. But when I click on other tabs, I can't see anything. They just won't open. What's my mistake here? Need your help. I tried to find the solution on bootstrap documentation, but I didnt come across with something like this. By the way I am just learning bootstrap. But it's like I am just copying and pasting, is this wrong? How should I learn this? It seems a bit harder than just css. Cause there are many classes that are written by default.. I don't want to memorize. So is it good that I copy and paste when I need?

I would like to achieve the following: (could be used for example to organize some sort of a speeddating event for students)

Create a schedule so people talk to each other one-on-one and this to each member of the group. but with restrictions.

• Input: list of people. (eg. 30 people)
• Restrictions: some of the people should not talk to each other (eg. they know each other)
• Output: List of pairs (separated into sessions) just one solution is ok, no need to know all of the possible outcomes

eg. Group of 4 people

1. John
2. Steve
3. Mark
4. Melissa

Restrictions: John - Mellisa -> NO

Outcome

Session one

• John - Steve
• Mark - Melissa

Session two

• John - Mark
• Steve - Melissa

Session three

• Steve - Mark

John and Mellisa will not join session three as it is restriction.

Is there a way to approach this using Python or even excel?

I am especially looking for some pointers how this problem is called as I assume this is some Should I look towards some solver? Dynamic programming etc?

I got a DataFrame and when I use print(df.head()) it looks like this:

The final section that says "Cardio + Core" shows the background color being black, but for the rest, it doesn't. I tried doing them separately but nothing works either. I'm assuming its a simple mistake I made somewhere, especially if it works for the "Cardio + Core" button. I also ended up giving each button a number, such as: "btn1", "btn2" etc. Is there a much cleaner way to do this? Especially since I have more buttons on the page.

Consider these models:

Is it possible to assign a one-on-one mapping between topic and client in Kafka, i.e., can Kafka scale up if we want to assign each clientID as a topic (number of clients may be up to millions)? If it is possible, is it advisable to do so?

More importantly, if such a scalability is not possible, does there exist any other message queue supporting Publisher-Subscriber model that can handle such a large number of topics?

In our cluster the dfs.block.size is configured 128M, but I have seen quite a few files which is of the size of 68.8M which is a weird size. I have been confused on how exactly this configuration option affects how files look like on HDFS.

• First thing I wish to make sure is that, will ideally files all of the size of the block size that already configured? Here I mean ideally file and block in a one-on-one mapping
• If the files are not inherently small but are generated by MR jobs, what can be the possible cause of these small files?
• One more point to add is that we are using the hive dynamic partitioning function which I am not sure if is one source of the problems. For the source of small files I have checked this blog but it The small files Problem

But the situations don't really match mine which makes my confusion remains. Hope anyone could give me some insight on that. Thanks a lot in advandce.

I'm new to react-redux and I'm having an issue with a web-app I'm developing. The app should have a user log-in functionality, it should be able to fetch and display a list of games from a database api I made, and it should be able to display information for a specific game from that list when it's clicked.

I have the user log-in functionality working perfectly, but the game list and specific game details don't initially display in the browser. If I look in the redux devtools, the action is dispatched and returns the correct information to the state, and if I page-through the devtools (push the play button), the list will show up in the dom, and stay until I refresh the page. The same is true for the game details.

I'm not sure what is wrong. I tried adjusting the react components and containers I'm using, but nothing I can think of / found in other posts seems to work. Maybe it's a problem with how I have the initial state set up (I have a initial state in both the user-login reducer and in the games reducer)?

I'll post what I think are the relevant blocks of code in this post.
