₦airaland Forum

Hi guys. Anymore updates especially from those who did the interview in Abuja?

can someone explain to me how to avoid being blocked by nairaland's s.t.u.p.i.d. bot

Nairaland has to train its spambot. It kicked me out again yesterday. And at least nairaland could give a helpful less annoying reason instead of 'reason: you were blocked by anti-spam bot, '

Anyway, My solution using python. First of all, python does not have arrays. Its data structure similar to arrays is Lists and the difference is that objects of different types including other types of data structures can be stored in a single lists.
Also, python allows you to create static methods by using the 'staticmethod' decorator.

I've commented my code so it should be easy to understand

Constructive (extremely inefficient and has the potential to run for ages):

class C:
    @staticmethod    
    def load_shed_d(l, num):
        """
        C.load_shed_d(3,4,5,6,7],7)------>6
        This function takes a list and an integer and returns the number closest
        to the given number.
        """
    
        highest = 0
        for x in range(len(l)):
            if l[x] > highest and l[x] < num:
                highest = l[x]

        return highest

since its a static method, you can run thus: C.load_shed_d(list, int). With the example given it runs in 0.0 second

For the efficient (destructive) solution:

class C:    
    @staticmethod
    def load_shed(l, num):
        """
        C.load_shed([3,4,5,6,7],7) ----> 6
        This function takes a list and an integer and returns the number closest
        to the given number.
        """

        l = sorted(l)   #sort ascending to make things easier
        cache = l
        for count in range(len(l)):
            size = len(cache)   #needed so the list can be divided into 2
            up = cache[size/2)] # The first half of the list
            down = cache[size/2:]   #The second half of the list
            
            # If the highest num in up is less than the least num in down
            # and if the least num in down is greater than the given int, 
            if max(up) < min(down) and min(down) >= num:
                return max(up)
            
            elif max(up) > num:
                cache = up      # Shed the 2nd half of the list
                
            else:
                cache = down    # Shed the 1st half of the list

With the example given runs in 0.0 seconds

Python doesn't have arrays. Python's similar data structure is called Lists and the difference is that objects of different kinds can be stored in one list.

In python, a static method can be created easily by using the "staticmethod" decorator so that a method - static() in a class - F can be called without instantiating the class like this: F.static()

Anyway this is my solution:
destructive (and by far fastest:

class C:
    @staticmethod
    def load_shed(l, num):
        """
        C.load_shed([3,4,5,6,7],7) ----> 6
        This function takes a list and an integer and returns the number closest
        to the given number.
        """
        
        l = sorted(l)   #sort ascending to make things easier
        cache = l
        for count in range(len(l)):
            size = len(cache)   #needed so the list can be divided into 2
            up = cache[size/2)] # The first half of the list
            down = cache[size/2:]   #The second half of the list
            
            # If the highest num in up is less than the least num in down
            # and if the least num in down is greater than the given int, 
            if max(up) < min(down) and min(down) >= num:
                return max(up)
            
            elif max(up) > num:
                cache = up      # Shed the 2nd half of the list
                
            else:
                cache = down    # Shed the 1st half of the list

For the constructive (very inefficient because it loops through the whole list):

class C:
    """
    C.load_shed_d(3,4,5,6,7],7)------>6
    This function takes a list and an integer and returns the number closest
    to the given number.
    """
    
    @staticmethod    
    def load_shed_d(l, num):
        highest = 0
        for x in range(len(l)):
            if l[x] > highest and l[x] < num:
                highest = l[x]

        return highest

sorry, nairaland-bot refused to inform me that you had replied

P.S i've edited my post to take care of some redundancies

with python

code:

def nairaland(word):
    #w = []-----------> redundant. I forgot to delete
    for x in range(len(word)):
        t = x
        for j in range(1,len(word[x:])+1):
            print word[t:t+j]
    print '""'

If you must have a recursion:

def nairaland_r(word, flag=1, w=None):
    #if not w: ---->redundant
     #   l = []
    #else:
     #   l = w
        
    if flag > len(word):
        print '""'
    else:
        for x in range(len(word)):
            print word[x:x+flag]
            if x+1 > len(word)-flag:
                break
        f = flag + 1

        nairaland_r(word,f,l)

Edit:

def nairaland(word):
    for x in range(len(word)):
        t = x
        for j in range(1,len(word[x:])+1):
            print word[t:t+j]
    print '""'

def nairaland_r(word, flag=1):
    if flag > len(word):
        print '""'
    else:
        for x in range(len(word)):
            print word[x:x+flag]
            if x+1 > len(word)-flag:
                break
        f = flag + 1

        nairaland_r(word,f)

@ tundebabzy

I have read tons of your comments and you are an intelligent guy, and I also disagree with on this issue. As simple as NL seems, it would be a lot of hard work to recreate without using a CMS; do you know of any Nigerian forums that were built from the ground up? I did not mean to be disrespectful to Nigerian programmers who labor everyday to gain knowledge and to put food on their tables; I only gave an honest assessment about the level of skills of the average Nigerian programmer. We still have a long way to go.

I totally agree with you that most Nigerian programmers are average. That is not because they(we) are Nigerian but because of the environment they(we) find themselves(ourselves). I have a classmate who is an engineer in facebook. He works on privacy. He left naija to study in howard uni and before leaving Nigeria, he never ever tried to program.

Django is a python web framework and is very cool i have worked with it some years back (2006). but i personally prefer Yii framework from PHP http://yiiframework.com

Frameworks of any language make such projects very easy. Ruby on rails would more or less be like magic so guys, please dont run down everyone, to be honest, recreating this site wouldn't be half as challenging as its being made to seem.

Has anyone here heard of web frameworks? A django expert will recreate this site in less than a week plus django is free, very popular and open source. Updates to the framework are pushed when new security tricks are discovered.
The only thing I know MIGHT be hard to recreate is the amount of traffic on nairaland #shikena

You are all sick idiots, extremely dumb. Your statement shows your brains will be too small to fit into an ampiclox capsule and each of you definitely have the IQ of a brick.

I'm no longer following the topic so don't even bother to reply

python solution:

<code>
import time

def check_palin(st):
t1 = time.time()
stripped = ""
for ch in st:
if (ord(ch) > 64 and ord(ch) < 91) or (ord(ch) > 96 and ord(ch) < 123):
stripped += ch
t2 = time.time()
print 'running time is %f' %(t2-t1)

return stripped.lower() == stripped[::-1].lower()
</code>

Ideally I would have imported re so i can use regular expressions to strip any non-alphabet from the string instead of looping character by character.

Fayimora:
I left that project euler after 20 problems cause its all maths, no berra challenge

Yup I agree, and for some of the questions, you just can't solve them by brute force efficiently.

hahaha. This is a project euler question

i think I am the only netizen with username tundebabzy,  and I have been trying my hands on project-euler,
And thanks, i'm seriously expecting your input.
I should be sleeping now but let me see what I can do to fayimora's homework

I wrote my test 2nd June. Relax guys, didn't you notice that all of you guys that did your interview earlier were those in Lagos area?

July 13, Abuja

errrr, I just got an invitation for BAT interview,

I just hope EFCC doesn't have the same impression about hacking as most of you. The doubt if the police even know what I.P Address means talk less of sql injection. By the way, we no hear anything about the stunt some dude(s) pulled on NDDC website.

Mobinga:

Lol, I also saw that

I disagree with this bro. .'Cos a plane was used during the 9/11 attack doesn't make the plane bad.

Narrowing it down, Hacking IS NOT bad. .the intention is!

Dude, lets not confuse ourselves with english, lets leave that for the English folks. Hacking used to be good, now its not. Saying that its still good is just denial.
Before now phones were JUST for making/receiving calls. Now they do much more, browsing, multimedia etc. To insist that phones are JUST for calls will not be correct. It was then, not anymore.
Hacking was cool then, not anymore.

Dude what are you saying. Now smartphone and land phone have been added to the dictionary. I guess that proves to you that there are different kinds of hacking, duhhhhhh!

Number_One:
Hacking Defined:
Hacking is unauthorized use of computer and network resources. (The term "hacker" originally meant a very gifted programmer. In recent years though, with easier access to multiple systems, it now has negative implications.)

Hacking is a felony in most other countries. When it is done by request and under a contract between an ethical hacker and an organization, it's OK. The key difference is that the ethical hacker has authorization to probe the target.

While hacking is greatly associated with security break ins nowadays, that is not the only definition of hacking.

Hacking (The real definition) generally means exploring the details of a programmable system and stretching its capabilities. Those hackers that break in to security systems are basically doing the same, exploiting a deep knowledge of the system (just that for their selfish and criminal intents). So also did the creators of the internet and microsoft, server replication and cloud computing, etc.

A lot of things we do as programmers can be called hacking. For example if you are a web programmer/developer/designer, you would know that IE is a nightmare. However, there are things we do that leverage on great understanding of the browser so that we can stretch of enhance its abilities. A very common IE hack is the conditional comment: <!--[if IE]>    CssCode<![endif]-->.

For javascript, when you visit a page, clear the address bar and enter this code: javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 You will be able to edit the page (without saving though).

You can't just say hacking means breaking in to a computer, its just like saying anybody that has a gun is an armed robber
