Web development. Desktop applications aren't profitable because of how easy they are to pirate. A lot of companies are moving to the cloud now. Even adobe has cloud versions of its popular software. You can use the same languages and tools for web development to do desktop development. If you know javascript, you can use electron to do desktop applications. I might be wrong though.

Thank you, you are not wrong about electron. I read about it somewhere. The second question please, are web apps the same as website? This usually confuses me.

tensazangetsu20:

Yeah but you can also get full time remote jobs online that pay very well.

sir, you are someone I really respect when it comes to programming. I need your input on this, please which should I learn, web development or desktop application development? Please kindly state reasons if you don't mind. And secondly, is web development the same as web application development?

I have HND, I am a WordPress developer, I am good at other languages e.g Python, php, JavaScript, I have indepth knowledge of TKINTER AND DJANGO, OP companies beg me to work for them with reasonable pay. Just look beyond your so degree.

please bro, how good is this tkinter? Have you had any issues with it besides its looks? How would you rate it, satisfactory?

Don't be confused. Am a programmer fullstack developer. Go for software engineering (development). That's what is lucrative now. Companies home and abroad including government agencies will need your skills. Infact in just 2yrs of my experience,once I mention programming,or software development,and marketing in an interview,even banks can't resist me. I choose to work from their pay. Am working with MTN and am comfortable with the pay now. If you have a child writing jamb,or yet to,advice him or her to go study computer science or engineering and focus in software development. The future is software,and you'll be glad to thank me later. A friend of mine,a doctor is earning five zeros (precisely 180-200k monthly),
his car and mine no be mates. You hardly see a software developer in MTN,Glo, Airtel, Google, Amazon,yahoo mail,even in gov.offices like Jamb,waec,inec,and other companies earning less than 700k at minimum a month. It's not blood money,that's where the world is relying on currently. Goodluck as you make your choice.

I actually sent you a pm, but am not sure how it works. Would love to ask, please which branch/ type of software development is advisable to go into?

Naijatask:


C++, C# and you can also use JavaScript, using the Ionic framework.

OK, thanks for the response bro. Was considering using python for it since I have already started learning it. Would have to reconsider. Thanks man.

Naijatask:
The question should be, why do you want to become a software engineer? Is it for a hobby? Or to increase your chances of getting employed? Or to create a product which will solve problems?

Well, if it's 1 And 3, then you should make research and if it's to get employed, then be ready to go on a long journey.

There are various aspects of software engineering like web development, mobile development, enterprise software engineering, data science and Artificial intelligence.

If you're diving into mobile development, then using Java or kotlin as a programming language to develop android apps, and using Swift to develop IOS apps.

And if it's web development, then learning react or angular as a front end framework and using a framework like bootstrap or materialize to back it up (I won't even mention HTML, CSS or JavaScript as those should be obvious to you already that you must know them before learning the aforementioned frameworks above).

Then you still have to learn either Python,php, node js or java as a back end language. And don't forget, you'll still need to learn a database language like my SQL or mongo dB.

Then you'll learn how to deploy a website's to the internet. Did I forget you'll need to learn how to test for bugs after completing your web app before deploying it? (PS: all these are needed, if you wish to be employed, else most of them are not needed if you want to become a freelancer).

As for enterprise software development, you'll be needing languages such as java, c++, c#.

As for both data science and artificial intelligence, you'll need to learn Python algorithm.

So, welcome to the frustrated guys club, where we get headache over a closing parentheses we forgot to insert at the end of the program

please what about developing desktop applications? Windows in particular

Ha!!! What happened? Was reading and all of a sudden, it stopped. Op, what you were dishing out here was pure fire. It would be great if you could continue with it. Thanks for the knowledge posted here.

PCA is not the right technique from your analysis. However, I will come down to the level of your analysis and explain it this way. First, columns not row pls. So check the way the data was coded. Second, since what you got is 5 variables from 35. It thus, mean the other factors did not load sufficient to be counted as part of the features. So when rotated, 5 features only was valid to be counted as a part of your model, also I guess you didn’t specify to it the number of factors you needed. So for it to produce 5 features it then mean other features are not supposed to be part of the model. So only 5 variables out of the 35 are valid. Third, When the name vanishes you are expected to check the items in the 5 features and take an action and that action you take would be dependent on the basis of where the features were obtained. If theoretical you are expected to check the items and be sure they allow you rename the vanish feature based on previous theoretical underpinnings. I will stop at this point. But you used a wrong example so I really can’t explain more.

hmmm! OK o. Would do more digging into it. Thanks man

ejibaba:


Multi group analysis. Since you intend measuring differences in groups. I hope I got you right?

OK, gotcha. One more thing, why is it necessary to scale our data before conducting kmeans?

I noticed something, though people say it's wrong. But anytime I don't scale it (standard scaler) I find it really easy to get easy understanding from the data. That is after picking my n_clusters from my elbow plot.
I then put up some features in a scatterplot then set hue= Clusters.

When I do something like the above without scaling, the features are very easy to understand and easily grouped. For instance, if I don't scale it, I might go with a figure decided by the elbow plot, let's say 2 Clusters.

Then I pair some features in a scatterplot. Let's say features, "credit amount" and "age". Then set hue= Clusters. Now, in the chart I might see two different colors representing some interesting findings. Example green color may indicate people with a credit amount of below 5000, then yellow may indicate people with a credit amount of more than 5,000. This is so easy to discover and make meaning of by mere looking at the chart, the scatterplot.

However, if I scale the data and try the above, it's always difficult for me to make out any meaningful thing from what I plotted.

That's why I am asking, is it really necessary to scale our data before carrying out kmeans elbow plot.

Sorry I am asking too many questions o. @ Ibromodzi, I don't mean to derail your thread. I am a huge but silent follower of your posts.

ejibaba:


I want to believe the meaning of the abbreviated “PCA” is principal component factor analysis. It is used to show interrelationships of items and how they load on a factor. It is also used to reduce the number of items in a scale. For cluster of people in a group why not MGA.

Yeah, principal component analysis. Don't get you, sorry, please what do you mean by MGA?

ibromodzi:


Principal Component Analysis is used to reduce the dimensionality of a dataset which contains a lot of variables. PCA allows you to bring down this number of variables by creating new representative variables that are not correlated in vector space and can be used in your analysis.

With PCA, you are able to reduce the dimension of your dataset while minimizing information loss at the same time.

Brother, I know all these. What I am trying to seek is, how do we interpret / read meaning to it. Most of the features are compressed, in the process we loose alot of meaning from the data.

Let's say for instance, I have a data that contains 1,000 rows and 35 features. (first name, last name, age, height, weight, salary, total balance etc) before I perform pca on the dataset, I can read and interpret the features. I can tell that row number 1 has observation of (John, Smith, 39, 1.7, 80kg, 20000, 100000 etc) and the rows go down till like row 1,000

Now whhen I perform pca on this dataset, the 35 columns might shrink to 5 features. The feature names would vanish. The new result/ output that comes out for the dataset we have performed, how do we read meaning to it? It's basically almost impossible to make meaning out of it.

And another thing or problem I discovered with it is, once I build my model based on the pca output. I find it difficult to reuse that model for another dataset that I would love to make predictions on. It would say something like the new dataset doesn't have the same features as that used to build the model. Even when I have performed pca on the new dataset I want to predict.

So that's why I am asking, what's really the use of this pca of a thing when I can't make out meaning from its results and I am finding it really difficult to reuse a model I have built from a dataset that I used pca on.

Don't know if you understand me. Sorry for the lengthy read.

Nice thread. Really informative. Would want to ask, please got any idea why pca is used? And how can one make meaning / interpretations from it? Reason why I ask is, why is it useful since I can't seem to interpret it by seeing which Cluster of people belong to which group unlike before pca is performed on the dataset.

Hi! How has the job been so far? What and what do we need to competent in for us to be very good at this role? Reason why I ask is, I am considering getting into it

tensazangetsu20:

I swear to God you have been thinking what I have been thinking. This is the advantage of freelancing. There's a very huge disconnect between what gives money in programming and what people are all learning. The things that even gives money sef there's hardly any tutorials out there. You have to breathtakingly go through documentations and continue trying and failing. I am presently building a Gatsby WordPress theme to sell on envato and once that is done I am diving deep into the salesforce ecosystem. Salesforce also has an app ecosystem like sap and there's just 3000 apps. Each paid app has a yearly revenue of around 1 million USD. Salesforce also added E commerce last year for B2B and b2c and with the acquisition of slack, it's not a giant to ignore at all. I will learn Shopify too but Shopify is mostly for small businesses. Salesforce is for enterprise level stuff but salesforce first and there's very few salesforce developers. 83 percent of the salesforce certifications given out are for Admins. Everyone is avoiding the development part of it whereas companies are looking for salesforce developers left right and centre. Extremely true about what you said. Build once, sell and maintain. And the scarcity of this niches makes it really easy to get a high paying job as a developer. Look at iOS developers. They are scarce and in turn they require really high salaries. It's the same for this niches. If a company is looking for a salesforce developer in Nigeria today, they won't get anybody and if they eventually find someone that person can charge 4 million a month as salary and nothing will happen.

this post of yours is fire. Thanks for dropping this Insight

Escape from sorbibor was the only movie that made cry like a baby. Danm! those nazi's were just too heartless.

Escape from sorbibor is child's play. Check out Holocaust. It has about 3 parts or so. All based on the nazi regime. It's extremely brutal

Film - 'The Champ'

Scene - When the father dies after a boxing match, and the son(one small boy) was telling him to wake up.

I can't watch the film again - it was too traumatic,

This film, omg. It will make you cry. I remember a lady watching it in our crib back then, she cried and cried and forgot her scarf at our place. We had to return it to her days later. Beautiful movie

Zabiboy:


I actually said that for those looking to monetize their skill in the short run...cz this data stuff is a long run stuff as regards opportunities in Nigeria but app/software/web dev. is already in a force.

Hmmm! If you don't mind, please can you list out the learning part one should follow in order to secure a project / job as a web/ mobile app developer. Please

How come, no lady born on 7th May here so far.

Okoro should be an ancient bini name

Chiledu means nothing in Urhobo language and we don’t answer it

Please easy with the lies

Isoko and urhobo used to be one ethnic group so this example isn’t valid

Thank you very much for this, I was almost calling him out for his ignorance and myopia until I saw this. All my years in urhobo land, udu, I have never ever heard or seen any one answer the aforementioned names. Okoro, isn't even urhobo sef. Thanks.

Abcruz:


It's not just about reading it though. You must implement it step by step on your PC to truely understand it. As for YouTube, just download any tutorial with satisfactory comment. I didn't use a specific tutorial I just watched to know how it was practically done.

Most of the things I learnt were gotten from that book I recommended.

OK thanks. The thing is I am using Jose Portillas video but he doesn't explain in depth, reason why I need a book. And the site you gave for the book, did you mean bookdotcome? Thanks again

Abcruz:


"Machine learning mastery with Python" by Jason Brownlee

It is concise, straight to the point and practically oriented. I learnt and developed models with it. You can get it at b-ok . xyz

I'll also advice that you take some YouTube tutorials along your learning path.

Best wishes!

thanks, I sincerely appreciate. Off to download and jack now. Thanks Thanks again. Please Any youtube suggestions?

Abcruz:


Well said!

please can you suggest a good book/pdf on machine learning? One that doesn't focus solely on the maths aspect only, but explains the codes and algorithms.

Please I need your help in making up my mind. I was recently invited for an interview for a teaching job at Mater Christi Schools igbogidi Delta State Nigeria. Please I'll greatly appreciate it if anyone here can give me the 411 about the school. Especially as regards to:
1. Environment and accommodation
2. Cost of living
3. Pay

Note: no. 2 & 3 are very important.

Thanks in advance.

don't understand what you mean by cost of living bro, if only you could be more explicit.

nwele2017:
Xup, did you go for the interview? I was invited but I rescheduled it for next week.

are you in warri? I thought you were in owerri.

Always attach yourself with people that are willing to share valuable information with you whenever they have, and you in turn would do same so as not to miss out on a clear PR opportunity. Also, when you feel the time is right for you to submit your visa application, please do so without proscratinating cos no one knows tomorrow, some of my friends failed to apply for 190 last year, and are now being forced to go back to student visa or partner visa (190 is currently on hold in my state due to the pandemic) to stay in the country pending when the state govt start receiving applications. That's my explanation.

Please, if you have a link that deals with PR in or to Australia, and stories surrounding it. Please kindly share here. Thanks
