Hello everyone,

In the spirit of Christmas I'm giving away 100k in airtime to students. That's 2k airtime for the first 50 students. I would have made this cash, but for some reasons I can't at the moment. If you need this in cash, you may just want to sell the airtime to those who need it in exchange for cash. If you are interested, just follow this procedure:

- You may indicate interest here. Please do not drop your phone number here.
- Send a PM
- I'll ask for a snapshot of your student ID and your phone number in response to your PM.
- Once your details are confirmed okay, you should get the airtime in a few mins.
- If your account is created after December 22, 2020, I'm sorry I won't be replying your email
- Please understand that I will be sharing the handles of those who receive airtime here for record purposes

Goodluck.

That's all folks!

Lately, I have been looking to mining relationships that may be existent in the network of relationships possible on a thread on Nairaland. If we collected data from any one thread, say this thread for example, we can define relationships between posters who quote each other in reply to other posts. If many more posters quote each other frequently than they do others, it is possible they could form a cluster of relationship independent from other relationships on a thread. I tried to look at this problem as a spectral partitioning problem and used linear algebra to examine possible solutions.

So, I scraped the data from this programming post on Nairaland and tried to look for clusters of relationships visualized as a directed graph. The direction of the edges indicate who quotes who. We can define this as a relationship between source and target. A user in the source column has made a post and quotes the target. Multiple quotes have been separated into separate observations. The first picture shows the kind of graph we expect. The second picture shows a sparse matrix defining the relationship between any two node. This is after symmetrizing the resultant matrix we obtain from the directed graph. The last picture shows the cluster we form using the second smallest eigenvector of the Laplacian of the matrix. This is also known as the Fielder vector.

That last graph reveals the two groups inherent in the data based on interaction between posters. In this particular dataset, the main center of interaction is the original poster (OP) who is Paapii3d. The groups appear to be divided based on those who have or did not have interactions with the OP. When the individual groups are examined, we find that users clustered in the top left are less likely to have interacted with Paapii3d, while bulk of the other users are more likely to have interacted with the OP, or interacted with those who interacted with the OP. The average number of interactions in Group 0 is about 1.1, while the average number of interactions in Group 1 is much higher at 2.12.

This kind of solution can be used to identify communities in a graph, especially, as in this case, where there is a main center of attraction. I'm working on putting the notebook which goes into details about the solution approach on github. If anyone is interested, you can let me know and I'll send you the link.

Quite a number of Naija guys and babes start out thinking the grass is greener on the other side. However, depending on one's orientation and priorities, one may come to realize that it simply isn't for him/her. In most cases, it is a win some to lose some.

You've put it rightly. There honestly should be no room for looking down on people, whether white, black or Nigerian. We should be more open-minded and quit being stereotypical.

Rbae:
I just came across this thread.

Good morning everyone. Please, I need help on the following.

A graduate who is a chemist and has a high grade in his B.sc and M.sc (a first class) is interested in a fully sponsored PhD scholarship in any Canadian university. Please, can you help with suggestions and how he can go about it?

Secondly, I need help on how to go about saskatchewan immigrant nominee programme. Do I need to write IELTS before applying? Please, help. Thanks.

Hi Katyamizotta, I'm also based in Ottawa and I am a member of the "Nigerians in Ottawa" telegram group too. But, I don't know about the "Nigerian Foodstuff/Marketplace" group. Hope you don't mind if I send you a PM so I can be added to the Foodstuff group. Thanks.

What do you need "Foodstuff and Marketplace" for? The one wey you dey chop never reach?

TransAtlanticEx:
Oh just shut up and get lost.
Imagine the audacity.
Let's see your account statement bla bla bla...
Even the EFCC has to go through a process to get this,let alone clowns on the web looking for attention.
I no want vex this morning abeg.
I see no single crime the guy has committed,actually you lots are to blame for just doling out cash to whoever online.
To what end?
You don't know you can be framed someday for funding terrorism or some Ill right?

Shut up there, mr. man! I have been following this thread silently and from all indications majestarial or whatever his name is, is more likely to be scammer than not. It is up to him to prove it and he should go above and beyond to do that. If that requires sharing an account statement, then he should do that privately. Nobody is saying he should post it here. Of course, it's obvious he is also operating this account, so it makes sense that you are defending him (or should I say defending yourself).

Homextras:
I was always afraid the lights had gone off when it appears as if the fridge has stopped working.. Obviously the thermostat regulating the temperature.
The lights has not blinked. My shoes hardly get dirty even after walking hundreds of metres.

As a youth try and explore other worlds, Nigeria is an upside down country - this is the best way I can describe it as I am short of words. A country where a PhD holder answers sir to a school certificate holder.

Has it been easy, sure no. But the pain is worth it. Well worth it.

Last word, don't do it for yourself, do it for your kids, your future generation, they will one day thank you.

Crazy, isn't it?

Cherrymia:
Do u still need the CAD?

Yeah

Anyone with CAD at a rate of 320 should please reach out to me. Trying to get some. Thanks

We should throw some challenges here from time to time. Get everyone spiced up on some topics in data science, R, machine learning concepts, bayesian statistics, etc.

Hi cochtrane,

Thanks once again for your help on the other thread.

At the emboldened, I hope I am not late to the party?

You didn't specify the date

It's come and gone already long ago

Twirelex:

I did an analysis on the nairaland data you scrapped... it's on my blog
https://talkrtive.com/post/text-mining-with-r/

thanks for sharing the dataset

That was really good. I immediately figured you used tidymodels while scrolling through. Nice job!

BelieverDE:

Brilliant! Thanks a lot, cochtrane!

You welcome, man

Hello Guys,

I'm kinda having a difficulty with Bayes Theorem. After spending hours to understand I decided to practice what I had learnt.

Abeg our mathematicians and staticians in the house coman help me ooo

This is an interesting question, and this is how I'd do it.

Prior probability that the woman has cancer is P(A) = 0.01
Let event A be that the woman has cancer
Let event B be that the woman gets a positive mammogram test
So, we are looking for the probability that the woman has cancer given that she gets a positive mammogram test, i.e P(A|B)

Using Bayes theorem, P(A|B) = (P(B|A) * P(A))/(P(B))
We know the prior, which is P(A).
P(B) can be expressed as P(B|A) * P(A) + P(B|not A) * P(not A)
P(not A) = 1 - P(A) = 0.99
We take P(A|B) to be 0.75, which is what the physicians claimed, i.e. the probability that the woman has cancer given that she has a positive mammogram test.

P(B|A) is the probability that she gets a positive mammogram test, given that she has cancer. That probability is 0.8, since the mammogram accurately classifies 80% of cases.

If you substitute everything into the equation, you get P(B|not A) = 0.27%. This means the probability that the woman gets a positive mammogram result given that she does not have cancer is 0.27%. This is the size of the false positives and honestly is too low. This would suggest that the test is incredibly accurate, which as we can see from the figures of 80% and 90%, is not the case. So, it is very unlikely that the 75% from the physicians is correct.
I suspect the "benign" case is the complement of the "cancerous" case, though it's not clear. If that's the case, then the probability of getting a negative test given that she does not have cancer (it's benign) is P(not B|not A) = 0.90, so that P(B| not A) = 1-0.90=0.1 or 10%. This is more likely the value of your false positives. If we compare with our earlier 2.7%, we see it is much higher. With this we can confirm that the physicians obviously are not right in their diagnosis.

Paccus:

Why must a person be liberal at all times, what if a person is conservative??

I think "liberal" here just means keeping an open mind. I don't think they are advising you to be politically liberal. In Canada, and I'd say generally in life, you want to be tolerant of other people's beliefs, inclinations or idiosyncrasies.

Temas:


I am interested too! Can I send you a PM?

Yeah, you can send a PM. I see that a number of Nigerians in Canada are now interested in data science/ machine learning, whether as business analysts or managers.

FlappaNozzle:
Hello my people,

Please if you are currently into or building a career in data analytics, business analytics, data science. I need a mentor o..or a study partner.

I am trying to change career to IT (data specifically), the journey get as e be. I have a huge flair for data. Currently learning powerbi on edx and Microsoft learning. My plan is to do the Microsoft licensing. I need expert advice.

If you are in this field, let's talk, if you are like me trying to delve in let's relate...the more the merrier. If you are an expert and you have advice for me..kindly let me know because mehhnnn I just realised that the older you get the more difficult its is to learn new stuff or maybe it's just me! This is really hard!

I can teach you some data science

Hello Everyone,

Please i want to ask which platform you use to convert your CAD and send naira to your naija account. I use MoneyTangle but they have a monthly cap and i have reached the limit. I still need to send more naira to Nigeria. Any suggestion please. Thanks

Can I get some of your CAD? I’ve got naira

Limitededition10:
Una no dey tire for this abuse matter, for how many pages now, una just dey drag the issue.

If your husband slap you, call police because you dey Canada abi na saner clime, if your wife insult you, go call police too make una marriage end, nobody cares.
Abi na only married immigrants dem do Canada for, shuu
Make una talk better thing as per recent updates post covid for incoming immigrants to learn from abeg.

The thread is now very dry and boring to silent readers because of these incessant abuse talk

Why should it matter that "the thread is now very dry and boring to silent readers because of these (sic) incessant abuse talk"? Is the original purpose of the people who post to entertain you? If you found it boring, why not just move on to other more interesting threads on Nairaland? Or is the forum suddenly running out of pages so that posters now need to be conservative?

I just don't get why you expect people to be looking over their shoulders because they are exhaustively discussing "marriage matters". They certainly don't owe you or anyone or Seun anything, if they want to flog this issue to death. This forum is built for talk, regardless of quantity. If it's something you don't enjoy, you've got a thousand other threads on Nairaland to visit. Don't tell people what or what not to do.

Dum20:


He did not share any Excel file. He posted that and was asking for people to bid to do it.

He shared the attached image though.

Can you explain the steps for on how to approach so we all learn

Use an excel sheet and a chart that updates in real time after user entry. That should be appropriate.

lymelyte:
did exactly as you suggested putting the csv file in hp folder but same issue

Check to make sure your file is actually a .csv file.
Right click on it and check the file type. Make sure it's not Absenteeism_data.csv.csv"
Open it and actually save it as a .csv file. What causes this issue sometimes is that the file type is wrong.

Guys, if you are curious about linear algebra and its related visualizations, you can check out 3blue1brown on youtube.

Can one get into trouble to scrap for webscrapping a website??

I need answers please

I don't think there's anything wrong with scrapping a website. But if you assess any website too often (using a script), they'll mostly likely ban your IP.
Now, while there may not be a problem with scrapping and collecting information, there may be a problem with using the information. The laws aren't so clear, so you may have to find out how it applies in each case. Basically, it just means you have to be careful with usage of data you collect.

Tesvin:
Pls how do I tell my boss that I want to start playing the role of a data analyst in the company.

I work in a small company that is into the production and sales of a Fast Moving Consumer Goods (FMGC) .

I'm done learning excel and I'm currently studying SQL - mysql

This is a very interesting question I have some experience with, and I'll give you a good answer. Don't tell him. Just show him.
Get the data and do something magical with it. I'm not talking plots or charts. Far from it. Derive good insight from the data that you believe can significantly improve production if you guys adjust just a little teeny bit in the production cycle. Show him using the many tools at your disposal why you think that adjustment may work. He doesn't have to implement it, but once he sees the passion you are showing and the direction you are moving, he'll give you the role you need.
And if for some reason your insights are powerful, I see no reason he wouldn't at least attempt to use some bit of it.

Hello all,
I need the help of the house.
Does anyone please know someone I can reach at Unilag's record office for transcripts?
Thanks

izzou:


He just needs attention

No point raised

I don't even think he was ready to take any advice handed him. He has him mind pretty made up, not only on the subject of women, but also on the subject of his thread.

Drfernandez:



Those against @GuyInTheMirror wish for a good woman, what do you have to say, since all of you say that a man who insists on having a woman with good behavior is asking for too much.

Good behaviour is relative. You could have a woman of good behaviour who is a feminist. I don't that that features in OP's world. His problem isn't that he wants a woman of good behaviour; I think it is that he has his mind set on an image which does not good to him or to the woman he plans on meeting. More of that has a lot to do with the fact that he was raised in Nigeria and has assumed beliefs and methods that can't make him survive "in the abroad". He would function much better, were he permanently based in Nigeria, but I guess that's out of the question for him now.

GuyInTheMirror:

I am not surprised that someone can post this, this is typical of my response to someone up there. There are some people who are impossible to please, they go around looking for faults and trying to validate their own importance by pointing out inadequacies.

This is not a good way to live your life. Many intelligent people have read the post and were able to discern that I did not intend to feel proud but only wanted to give a clear idea of my situation and they also provided helpful suggestions.
It is totally up to you to infer what you want but I encourage you to try and always look at the bright side, I hear it makes one live longer.

Cheers.

Sorry, if that hurt. There's really no pleasing here. Just telling it as it is. When you raise a matter for public discussion, you bet you can expect wide-ranging responses. Sometimes, the truth itself hurts. In some way, I feel like you are not looking for advice. Or are you?

GuyInTheMirror:
MODS PLEASE NO FRONT PAGE!!!

Hi everyone, so I am not a new member of Nairaland.
I decided to create this new profile so that I can be annonymous.
I was hoping to speak with some matured people here about the issue of marriage.

I am a 34 year old man who happened to immigrate about 2 years ago, I am a very gentle and highly ambitious person and God has blessed me.
I work for one of the biggest firms here in North America , I used to work in a great firm too back in Naija before immigrating.

Now to the issue of marriage, I am in a kind of dilemna.
I am the type of person that values marriage and a quiet life.
I do not smoke, drink or womanise. I am actually the type you'd call a church boy. I dream for a respectful wife whom I can love and adore and build a family with.

But it seems being in North America makes that complicated.
1. Majority of the women that surrounds me are in their 30s. I personally would prefer to marry someone not older than 26 years for personal reasons.
2. Many of these women are closet feminists and they tend to be much louder than the personality I am looking for in a woman I'd like to settle with.

I have attempted to start relationships with ladies that tend to meet my description back in Nigeria, but I became shocked cos it seems once a lady knows a man is abroad they become lovey dovey. They start to pretend like they are saints so that has put me off as I do not want a lady to pretend for me.

The options before me are :
1. Look for someone that is close to my requirement here and marry her and hope for the best.
2. Look for someone back in naija and marry and sponsor her to North America.
3. Wait for 2 more years, get my citizenship, come back to naija and blend in like a regular guy and try to meet a lady that does not know I am an abroad person to avoid pretense then try to get a babe. (In 2 years time I will be 36 years old, is this not too old ?)

I would like people with a lot of insight to educate me on what appears to be the best option.

I think you need to open your mind more. These ideas you have are at best appalling and at worst sexist. That you are "abroad" is no indication that you have achieved anything or that you are deserving of a "young and ripe" (pretty much your suggestion!) 26-year-old. You need to re-calibrate your thinking and come to terms with your surroundings.

teewhydope:


I've tried scraping NL website to get your exact dataset but ive only had luck with links and title. i think i should be able to scrape author too from each thread. i want to understand the concept behind the sections column and the last two columns(frontpagedate and posteddate) because nairaland doesn't group posts by date and time. ive completed BS4 documentaion but i still don't know how to go about it.

The sections column is the section to which the post belong. Could be politics, romance, etc.? The frontpagedate is the date and time the post made front page, while the posteddate is the date and time the thread was actually created.
When you parse each title on the frontpage, you will see that it has a date and time associated with it. For the section and posteddate, you would have to go into the links and extract that. So, for each link you obtain, you go inside the link and you can obtain as much information as you want about that link. You could even obtain all the users who posted there and the time they posted.

kunleiky:


If I may ask cochtrane, is it possible to download from Github using a mobile device, or it's best done on a PC, cos I've been trying to download this dataset and it's only bringing the data raw,only allowing me to copy and paste, unfortunately not everything is copying.
Also is it possible to scrape it directly from Github?

Yes, it's possible to just assess the raw file directly using this link
