Why the need for building a new website? I think the solution to that is just to increase their bandwidth. Similar thing happened to CNN,SKY and BBC website on the terrorist attack day.I mean 9/11. Whereby people couldn't access their website. |

Re: Build A JAMB Result Checking Website To Win 150,000 Naira by Seun(m): 4 hours & 28 minutes As I said before, you cannot separate script performance from server capacity. A bad script with horrible algorithms can be 1000 times slower than a well-written script with optimal algorithms, such that you will need 1000 servers to do the job that one server can do with a good script. You can argue that in JAMB's case the script was not the problem, but you can't prove it unless you obtain the scripts currently being used by JAMB, benchmark them, and compare them with the best script written by participants in this contest ad running on the same server. Without this information, the entire debate is pointless, so I will need the debate to end right now. . ------------------------------------------------------------------ There's a touch of arrogance in your last statement, which doesn't sit well with me. Are you saying that we can not learn one thing or two from what other people have posted in this thread? I'm sure those who are interested in taking up your challenge have started working now. There is no need to be dictatorial about what opinions people offer. Lock the thread if you don't want people to question your authority/opinion! |

@Babaggio: It was just authoritative. Well, I'm sorry about that, but I'm trying to run a contest and it's so hard each time I come back to this thread only to notice that, apparently, a ₦150,000.00 prize is not enough to convince people to learn Python. |
Re: Build A JAMB Result Checking Website To Win 150,000 Naira by DualCore1: 11:31pm On Apr 01, 2012 |
dayhawk: @dualcore you are the only person to give a good answer because you sound like you understand the complexity behind complex systems. surely your data server architecture determines how master servers interact with slaves especially if you are restricted to a resource.I appreciate the time you have spent writing this and I like your logic. This may not work for very huge websites but it should work for JAMB. The only point of failure I see is if the servers are not much so the range given to rand() is so small it will almost always hit same number for a couple of connections. Taking this to the clouds may be risky because the clouds will never (as of my writing) beat a physically located dedicated server when it comes to reliability and availability. Seun: the entire debate is pointless, so I will need the debate to end right now.It is not pointless, you just don't see the point and that's understandable. |
Re: Build A JAMB Result Checking Website To Win 150,000 Naira by doncigalo: 1:31am On Apr 02, 2012 |
techytom: @doncigalo Sure, in regards to http requests and responses, u minimize as much as possible the number of HTTP requests that your app makes to the web server. The logic behind that is each HTTP request to the server and its corresponding response eats up CPU usageside (server ) and introduces incremental delays, so by minimizing the amount of HTTP requests you lower the amount of CPU usage and incremental delays thereby optimising ur app and preventing server overloading as well. As for the use of the timers, it is a way of benchmarking ur app, setting up timers in different code sections of ur app can find out with part of ur app is slow and optimising that section according. Another use of timers is to set the maximum time that an app should carry out a request, especially a server request , so if takes 2 secs to carry out a particular request, u cud write a function that stops that particular process if it exceeds more than 2 seconds. @dualcore How can a physically located dedicated server be more reliable than a cloud based one?? Thats not possible. I dont think your ever had the chance to use a cloud based server, cuz if you have, you would know the amount of redundancies that are implemented. Im talking about master-slave/master-master configurations in conjunction with a backup database that is based in another location (the backup process is even done via satellite), Im talking about standby generators (2 not even 1), Im talking about underground bunkers. Lets not forget the number of technicians, both database and network , that are looking after these systems 24/7/365 and even the security personnel as well. So how can a cloud based server be more reliable than a physically located server ?? Its not just possible. To prove the point; why didnt Safaricom, the company behind the MPESA platform (largest mobile payment platform),go for a local dedicated server ? They have the technical and financial capability being a major telco company in sub Saharan Africa, instead they hosted the application on a cloud based servers being hosted by a British company called Rackspace. This is a financial application that demands 99.9% availability. |

yamakuza: yamakuza, dualcore: in my next code i will try as much as i can to speak parsel tongue... i want to ensure Seun doesn't have a reason not to invest till he's hands down @dual core , the rand(1,15) will work very well,though its crude ... yet its still rand for Gods! sake. its worth more than just a try cus im certain it will work. seun: yeah thats necessary because some functions like 'for()' loop function will make your script as slow as 150s. if its looping a real var 5times above or looping a function jamb engineers are doing the wrong thing |

Seun, I have to say I have never seen anyone that gives out reward just to find the right person to work with. I am not interested in your money but may the right man research further and win this contest. This is what I have observed with jamb site. 1. It runs on IIS 7 2. ASP.NET scripts 3. Somewhere in Germany Running some simple diagnostic tools, I came to the conclusion that it is a terrible script / misconfiguration on the server's part that makes the site to go down. However, scripts should be able to properly configure the server. To reproduce my observation do the following: 1. go to http://jamb.org.ng/Unifiedtme/default.aspx 2. Start netstat (in windows I run it with -b to see all executables and addresses) 3. Key in a PIN/reg number...whatever 4. Go back to netstat and refresh the command. You will see 2 ports open just to check the result. The lesser port number eventually closes after some fews seconds (5-10secs?). The higher port to sidmach server stays open for about 2 mins. Now if we do the math in I.P networks, we have only about 65k ports minus about 1.2k reserved ports per I.P address. So roughly about 64k ports available to service millions of request. Imagine if the available 64k ports will all have to wait for about 120 seconds before they are free, how many backlogs will be waiting on the server? 2 Likes |

Some rules have been relaxed: - The deadline for indicating interest in the contest has been lifter, to increase the pool of contestants. - The deadline for submitting your final entry has been shifted forward slightly to Sunday 2nd April at 11pm. Go, go, go, go, go! Code away. @dell_net: Love the way you think. What you've observed is the HTTP keepalive timeout. Wrong conclusion, though. |
Re: Build A JAMB Result Checking Website To Win 150,000 Naira by dellnet: 4:45am On Apr 02, 2012 |
why do you say the connection timeout is not holding the resources? |
Re: Build A JAMB Result Checking Website To Win 150,000 Naira by Seun(m): 4:55am On Apr 02, 2012 |
I meant to say that while the 120s keepalive timeout is definitely tying down some resources, the issue has nothing to do with the number of TCP/IP ports (you can have more than 64000 simultaneous connections on a server). The problem is that every connection consumes some memory, and probably requires a separate thread depending on the architecture of IIS. There are probably also configured limits on the number of simultaneous active/pending connections, so when those limits are reached, the server will stop accepting new connections. |

I have things in the cloud and on the ground and I speak for my self and know what I am talking about regarding what's in the cloud and what's on the ground. People get swayed by the gimmicks thrown to them by the web hosting industry. I see beyond those gimmicks and tell it as it is. You really haven't seen stuff gotten lost in the cloud so you really won't appreciate staying on the ground. My views. |

A inefficient script would require a more powerful server to handle the same amount of traffic that a more efficient script would handle effortlessly on a wimpy server. [img]http://www.filii.info/g.gif[/img] |

Best ever written script, poor servers and technologies also Database structure/ admin equals a waste of resources. I guess the spec of trying to bring out best geeks or programmers should simply be limited to or changed to have ONLY Python based programmers. Allowing all other languages will do better to suffice for your former claim @Seun. Don't always be intimidated by PHP ok? @Programmers Money must not always motivate us to do things. When are most of us going to stop acting so hungry? Just so bad the world knowing how hungry some of us are. Even if you've not seeing such an amount before, be amazed with style before your PC and not publicly here. Success to contestants in Python. All my other PHP lookers, let's be cheering at them yet getting the same problem solved with our preferred programming language. One last thing, I think someone here actually needs Python coders and since none is showing up a better approach as this is invented to lure that needed coder out of his haven. ¤PHP for life!¤ |

Hypothetical question: What if you only do the retrieving of data once and convert the result into a picture that you cache (at data entry) on your server or an Amazon Web Service bucket? When the JAMB applicant comes, we simply use the USER ID or unique user hash to retrieve the appropriate file from Amazon. No hits on our db besides the login sequence and all the stress goes to the image server (wherever it might be). Besides, most people only check their result 1-3 times( a score of 60 in JAMB does not breed return visits). As for login, if you supply JAMB with a particular OpenID compliant email address, we can simply handover login authentication to Yahoo or Google and only use the verified user email to generate a hash for retrieving your image from AWS. If you are not registered with us, then NO hash and NO hash means NO result. (Side effect being that a hacked yahoo account means NO JAMB result :grin: ) 1 Like |

The money is too small compared to what the website will generate. ![]() ![]() THese are my requirements 1. I can only come in here when the prize tag is 2. I will be one of the administrators to the DB 3. JAMB will employ me on different base along side my co-workers If all these requirements are met then expect my script on Friday. |

kodewrita: Hypothetical question: What if you only do the retrieving of data once and convert the result into a picture that you cache (at data entry) on your server or an Amazon Web Service bucket?Memory is a more likely bottleneck than the CPU, so storing the data in a more bulky format (as an image) will probably slow things down because 1.5 million images would require more RAM than the data used to construct the images. Simple applications like JAMB result checking (and Nairalist) don't require advanced optimizations. Just design your DB and queries carefully such that each page requires very few queries, all of which are perfectly indexed, and your performance would be fantastic. 1 Like |

Seun, You should judge this work from IP stack down to http not just from http stack to the application itself. This will give you a fairer ground to judge the submissions of this contest based on the standards on how a webserver operate. You can surely have more than 65k connections to a http server but what about the IP connection? (IPv4 by far is the most common method of connection to the web.) Also note that some web-servers automatically spawn script base on the concurrent limitation etc. However, I don't want to spoil the hunt game so I reserve much of the technical input till the deadline is over. |
Re: Build A JAMB Result Checking Website To Win 150,000 Naira by kodewrita(m): 1:54pm On Apr 02, 2012 |
Seun: I see. If am getting you right, there's more to gain from MySQL indexing than incurring extra memory burdens due to externally requesting the images. My earlier assumption though was that all you had to store was the URL which could be given to the user as a static AWS url effectively incurring no cost from your own server with that borne by the client's machine. thanks though. Good stuff. |
