I don't know much about the algorithm except that some researchers have gained a fair amount of publicity
by claiming that they have reverse-engineered the algorithms.

You can get some more information on this page:

Hello Zeta,

How is this project going?

Keep me in the loop. Thanks.

I was going to ask what was the error message the OP wanted!

I like the fact that you had earlier posted a programming question( which looked like an assignment) and presented not one single description of the problem in your own words, which obviously had no responses but yet had the temerity to ask ANOTHER question with no personal input, just a word-by-word definition of the assignment and then proceed to ask for help and expect a different outcome.

shokergb:
it's not still working,let me explain myself a bit more,i'm searching through a database with a select query and i want to control the maximum number of searches,say 3 times.so i gues i need a loop that will terminate the search at say count 3.useful solutions would be highly appreciated.

I don't understand,
Do you want to restrict the amount of rows returned to 3? or,
do you want to actually search the table 3 times?

If it is the 1st then, you ONLY select once and then get the result and then only get the first 3 rows of the Result set

If it is the second, then well, I guess you are on the right path but what would you be trying to achieve doing this?

naija_swag:
When I see certain frequent posts by those who claim to be programmers who are supposed to be professionals I get irritated.This is especially rampant in this forum amongst incompetent Nigeria programmers who know nothing.

Why should you be laughing at this guy? Where you born with php in your dull brains? When you visit all those many tutorial sites hosted by experts from India,US and the Europeans,if their disposition are like those of the useless so called Nigerian experts(that will remain client programmers for a long time) who post rubbish to rookies,would you have learned anything.Was it not by reading other peoples(non-Nigerians) books and tutorials that you learned the little you know that cannot even bring to life a robust software?

Show me one framework or an open source php or any other programming project that you are a contributor other than putting one or two things together to create a website that is as dead as Nigeria?

Here comes, DEFENDER OF THE LAUGHED AT!!!

Now my normal first reaction to this is to return the verbal in equal venom but I see you have good intentions so I will pardon you

That a person 'insinuates' that he may laugh at a question being thrown out in the wild does not in any way detract from the fact that the person will still provide support for said question. You should try and not be so uptight!

You really don't know me but if you want to continue to insult 'useless so called Nigerian experts' , we have a thread for that on Nairaland > Programming section. Please go to https://www.nairaland.com/nigeria/topic-146070.0.html and feel free to insult away.

And I really don't program in PHP but I know enough to even help the guy. In your berserkers rage, you forgot to provide any help for the guy!

Glad to be of service!

These are one of those post that my normal first reaction is to burst out laughing!

Most importantly my friend, you can NOT iterate over a ResultSet ( which is what a select query return when executed on a table in the DB) by calling the SQL Statement again.

But here is what you want to achieve in PHP (using PDO): http://www.php.net/manual/en/pdo.exec.php

Let me know if you need any more help and I can post examples.

Hello,

I am feeling really bad because I am about to send you back to the Internet where you found 'nothing meaningful'.

Seriously what could you not resolve? The idea of Web Services is that you can pass certain parameters to the Web Service machine using ANY programming language whatsoever.

To create a Web Service client ( an application that communicates with the Web Service Server) using php you should try this for starters http://php.net/manual/en/book.soap.php. It contains useful instructions for communicating with a web service using Php.

If you need any more assistance, let us know.

Best of Luck.

Which begs the question, 'Why did you download it?'

From their site, I am guessing that JGrasp is 'An Integrated Development Environment with Visualizations for Improving Software Comprehensibility' which, to me, is a short form, modeling software for helping visually design UML Diagrams.


The last pure Software modelling App I used was Rational Rose( which was a very long time ago) so I doubt I can help here.

Have you tried their help document found here: http://spider.eng.auburn.edu/user-cgi/grasp/grasp.pl?;dl=download_jgrasp.html?

Hi there, I am pretty sorry to disappoint you but I am not a professional in Image procession ( did some Matlab image processing in Uni but that was pretty much it). But I have gone through the same process I would have gone through if I was developing the thing myself.

Firstly go here:
http://mindmeat..com/2008/11/java-image-comparison.html

It speaks mostly about the ideas required to perform this kind of Image comparison. Although it also discusses it with regards to Java, I think that you should strip your mind of the implementation details ( like the actual programming language used) and keep your mind on HOW the comparison was made. Like whether the image was broken down into smaller blocks before the checks were made and what not. Just check the steps basically.

Then go here:
http://www.codeproject.com/KB/audio-video/Motion_Detection.aspx

This uses a different library to perform the exact same tasks that you are trying to accomplish. You can also learn the general ideas presented here and see what you can do similar yourself. You may also want to look into the library and see what its capable of doing and if possible HOW itr does it.

Then go here:
http://www.java2s.com/Code/Java/2D-Graphics-GUI/AmotiondetectionalgoritmforusewiththeJavaMediaFrameworkAPIJMF.htm
This is actually what you want , but hopefully if you understand the ideas very well then you can go ahead and improve what is being presented in this code snippet.

Ok so, look into the pages and let me know if you need any additional assistance.

Best of luck.

are people still doing OCP.

programmers are finding ways of getting around the [b]obvious limitations [/b]of databases these days

Forgive me for my ignorance, but I am going to ask what are the obvious limitations you specified in your quote?

I posted a longer reply but that got flagged as spam and my post was not re-instated after my posting rights had been re-instated.

My view, in short was, Oracle was never really relevant outside telecom and it is not relevant now as most non-telecom companies are beginning to find new ways of reducing cost.

And yes, programming is 'not a beans'.

I wanted to post a reply earlier on but kept feeling that some one would post something less controversial than I was intending on posting but as no one has obliged you, here goes:

I don't believe there was ever a time that Oracle had a demand in the Labour Market. What bhappened was that some of the telecom operators that where actually using Oracle felt that to reduce running costs, they needed to get Database engineers to handle the DB layer of their telecom structure. So OCAs were recruited for these positions. You should note that very little experience was required for any of these positions. All that was required was for you to have OCA or OCP. Most times having OCP meant very little difference( whereas in a ideal situation, the OCP would be the head engineer or something, you can still find OCPs as Junior Engineers).
Then this is the funny part, All sorts of companies such as Hospitals, banks, Stock broking houses and Bureau de change shops seeing that telecom operators were employing OCAs and OCPs, started recruiting them as well even though they never had even heard or used Oracle ( in the case of many hospitals, stockbroking houses and bureau de change) or were never directly maintaining the DB due to security concerns ( as was the case in many banks). So this created the fake recruitment drive and currently the market is saturated.
No one is recruiting for a position they rarely will ever need, the money is simply not there! Oracle really never had any relevance in the Nigerian IT Sector

Heck, even I have an OCP but I probably can not administer an Oracle DB and I rarely maintain an Oracle DB ( my main core position is more programming, Software maintenance) whereas some of my foreign colleague have never attended a single OCA course in their lives and yet they can and do install, maintain and administer whole Oracle installations on Telecom operator sites.

As for being a programmer, well this is a bit common sense. Its a bit like saying that it is better to be a neuro surgeon than a pharmacist but 'surgery is not a beans', neither is programming. I don't really believe that we need Hardcore programmers like that, when you say Programmer I am guessing that what you really mean is someone very comfortable with SQL commands ( there are many types of Oracle/DB programming), I would say Yes. That is a better place to be than an OCA as I can bet most OCAs have never really managed an installation of even SQLite talkless of Oracle.

I once went for an interview once for a programming position. 40% of the questions were on Oracle and Unix,RAID, 40% were on Service management, SLA and ITIL , the remaining 20% were on Telecom. I never got asked a single programming question. So in Telecom , Oracle will never lose its relevance as is the same around the world. In most of the other sectors in Nigeria, I don't think it ever had any relevance.

Hi,

You should really mail me, I check my box way more regularly than I check Nairaland. I have my mailbox somewhere in the thread. Come to think I have been getting spammed a lot from ppl claiming to be from nairaland so maybe I need to modify the mail box so no bot can scan it.

As per your problem, what you need to do is probably find a way to get your byte array to a video display of some sort. Any clues? Apparently it has something to do with Java 2D. From my initial research it seems that you need to convert the byte array to an image , EVERY TIME YOU RECEIVE A FRAME from the webcam, changing or not. For the value in the byte array to change there must be something different in the captured from from the webcam. Image are liable to change at the slightest change in light or background images.

For Java 2D, you can go http://java.sun.com/developer/technicalArticles/GUI/java2d/java2dpart2.html

Sorry I can't send any books, they'll be simply too big.

Review and send me an email if you need additional assistance. If I don't reply, post your message here. I tend to delete any mails that has nairaland in it

It is not that straight-forward as to just say 'Use echo'.

Apparently( I say 'apparently' because I am yet to test this and as such can not say it authoritatively) echo is faster because it doesn't set a return value on execution but I think that there are other factors that you should take into consideration:

http://stackoverflow.com/questions/1006586/is-there-any-difference-between-print-and-echo-in-php-closed

It has some comments regarding the usefulness of the print statement and maybe you would want to look at that before deciding to use echo

I think what your brother needs to do is to choose a particular setting with a known maximum packet size, set the size of the byte array to that and then see how that affects the reading of the data stream from the USB bus.

Its not going to be simple but I fear that 'Trial and Error' is the route to use for such a task. It is what I would do.

Although from what I am reading in the Javadocs I don't think that the size of the byte array is really the problem, I feel that the Offset might be a bigger obstacle but this is just me. When you read from the USB bus, it will put as much as possible in the byte array.

What I'd recommend is that try creating a simple program that JUST reads the bytes using different settings and take it on from them, its called 'Divide and Conquer'.

Best of luck and let me know how it goes!

Both are expensive and hence unpopular.

Iphone is more expensive though and, knowing Apple, will probably always remain so.

If you want your applications to be bought in this country develop a Java or BB app.

The concept is quite simple.

A business entity approaches a MNO ( mobile Network Operator ) and they agree on a business proposal with the MNO being used as an advertisement or delivery platform. MNO informs the Business entity that they would want a percentage of ALL revenues generated by the advertisements.  You would want to know now that pretty much all the MNOs in Nigeria will shaft you ( cheat you), most of them take over 50% of revenue generated.

If your business can bring in money to the network, you have a negotiating point and can request a better percentage cut for your business.

So yes every time you subscribe to a network short code, your account gets deducted the required fee( N100 in the case you provided),  the message/registration requests gets routed to another 3rd party application which actually does the notifications or advertisements. ( in your case, you get sent 'Thrilling Love texts'

After a particular period , the Business entity and the MNO sit down and, based on the records of revenue generated by the MNO on your promotion and the original agreement, determine how much will be payed to the Business Entity.

If you want to know how such a System is designed, please ask in a separate thread.

No matter how scandalous and obsequious it may seem to be, Google is still your best friend when searching for programming solutions.

See : http://www.google.com.ng/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=splash+screen+vb.net&aq=0&aqi=g3g-m1&aql=f&oq=splash+screen+VB.NET&gs_rfai=

And you will see a fair amount of website that advertise code for what you are looking for.


And the same rule applies for the other 'Marquee Scrolling text' question you posted!

There is a lot of Intellectual dishonesty in this thread!

Firstly from the moderator. Whoever deleted the the OP's follow up post is a very bad person. The OP ( aitoehigie) has a lot of valid point made after the Opening post that have been deleted. I encourage everyone to read up on the OPs other post in his profile. Some are very sensible posts( There is the occasional mad rant, but we all have those

Anyone who just comes to this post and reads up the Opening post believes that aitoehigie is some mad person who want to just defame and humiliate Nigerian Programmers but this is not true. The most visited Nigerian Internet site is Nairaland which is simply an themed implementation of the SMF Forum framework. This is a fact! That Nairaland has such a following should still be applauded. What is worrying is that every other Nigerian Internet site that attempts to challenge Nairaland DOES EXACTLY THE SAME THING! Nothing more, Nothing less. Offer a forum that people can converse. That is it.

Even sites that attempt to COPY Facebook end up looking like Nairaland! Its a bit embarrassing really. Now I am not a huge fan of Social Website ( I log into Facebook once every month or so) but I am *honest* to know and appreciate the amount of technological input required to build such a framework.

All the OP did was to offer a challenge for Nigerian Programmers to do something different.Something original, no matter how small. Maybe the language was inappropriate but his follow-up posts ( that were politely deleted) offered more insight as to why he started this thread. He got insulted and probably banned.

A man writes a Post that summarizes theories provided by Paul Graham and it gets deleted yet someone makes 2 SEPERATE THREADS advertising a YAACA ( Yet Another Accounting & CRM Application) and the threads remain.

Not good!

You probably want to understand the concept of these data structures before implementing them at all.

After understanding them then try and implement them using an 'easier' language such as Python, Perl or Ruby before starting to implement them on something like C / C++.

I was of the believe that C++( maybe via the Boost library) had so many of these data structures already defined and just ready for use. Why are you still trying to implement them yourself? Academic purposes?

After checking the icaste website I have seen nothing to indicate that you can recieve your video stream from the Webcam using the provided drivers. I have read the Javadocs provided with the USB drivers and allI can see that 'MAY' allow for such is the readPipeIsochronous function. See below for the function description:

gemini_titan:
public int readPipeIsochronous(int iIntIndex,
                               int iEndpointIndex,
                               long lPacketSize,
                               long lFrameOffset,
                               byte[] baData,
                               int iArrayOffset,
                               int iNumBytes)
                        throws USBException
Read from Isochronous pipe. Read from pipe indicated to byte buffer provided. Data array is split up into packets of size lPacketSize. These packets are then read from USB bus isochronously starting at the current frame with offset lFrameOffset. If lFrameOffset is greater than MaxFrameOffset, the request is discarded. MaxFrameOffset can be found with getDeviceIsochronousFrameOffset(). Note, the current frame is calculated when the driver sends the request onto the bus. The actual current frame may have increased when the request hits the bus. If the offset places the request on a Frame that has already passed, the initial packets that belonged on the lost Frames will be discarded. If the offset places the request on a Frame that is yet to pass, the data will be delayed until it can be read from the correct frame. Method will block until all requested data is read, or Read/Write timeout expires. Use setReadWriteTimeouts() to adjust timeout settings.
Parameters:
iIntIndex - Interface index.
iEndpointIndex - Interface Endpoint index.
lPacketSize - Size of packet to be place onto each USB frame. The total requested data is divided into packets of this size.
lFrameOffset - Frame offset from current frame when this request hits the bus.
baData - Byte array for data.
iArrayOffset - Offset within baData to store the read data.
iNumBytes - Total number of bytes to read.
Returns:
Number of bytes read into array.
Throws:
com.icaste.JCommUSB_2_0.USBException - Thrown if OS encounters a problem or iNumBytes/iArrayOffset combination is outside baData bounds.

Sir Welly:
@kanirip

you might find it difficult to understand except you were once a computer sc/eng. student. No lecturer can runaway from teaching generation of programming languages without mentioning those old languages. if i may ask, what is your course of study?

I did Computer Science for 2 years in Akoka before travelling to the UK to restart and finish my BSc. The reality is that even if some of our graduates ARE good they may never achieve their potential, because a system that places you in a class of over 500 students in a room not designed for more than 80 students doesn't want you to give your best. It wants you to give their least!

Even if you insist on teaching Generation languages, PASCAL and Fortran are not foundation Programming Languages. Foundation programming Languages are Assembly, C, Smalltalk and Ada, maybe even Lisp. These languages introduce new concepts in programming. But not Pascal and Fortran.

Even in my UK University, I had a lot of arguments with our lecturers insisting that Comp Sci students ( considering I never really spoke with my lecturers in UNILAG this was a HUGE step) be introduced to more in-depth topics in Computing such as Operating Systems and Algorithms ( which other top Unis were teaching as part of their undergraduate program). they always declined saying that while me and some of my classmates maybe be OK with the material, most of the class would struggle as those topics were very technical. They did not want to increase the already high drop out rate in the department. I had to research these topics on my own!

Now, what worries me is that many MSc. students that come out of Nigerian Universities ( and some foreign ones) do not even understand the concept of a DBMS , talk less of an Operating System. I once met a woman , whom while claiming that she had 9 years of experience with Oracle, insisted that MySQL was a 'play-thing used on the internet'. Nigerian IT Specialists are to uni-directional and it starts from their educational system.

How sad,

Sir Welly:
All school systems take you through different generation of programming languages from 1st to 5th. So you get have an idea and how they work. Fundamentally, 1st generation programming languages are relevant to you as a computer science student.

I don't think anything is wrong if your friend is taught PASCAL or FORTRAN in school as an undergraduate. I was taught too in 200 level during my days in school. After all, a computer scientist must know the in&out of programming languages not just the recent ones. I studied computer science here in nigeria and i went through these courses.

I am not saying do not learn the fundamentals of programming! But I insist that PASCAL or FORTRAN are not ideal for teaching students programming in a University, not even the fundamental. If you disagree, then why don't we just go back and teach students BASIC and scar them for life

I feel that if you are going to teach students the fundamentals, you can group these fundamentals into the following categories with their corresponding programming languages:
a) Structured of Computer Programs: C/C++/Java/Python
b) Object Oriented Programming : Smalltalk/Java/C++
c) Network Programming : C
d) Distributed Systems: Java/C++/Erlang
e) Algorithms & Data Structures:  C/C++
f) Operating Systems: C/C++
g) Functional Programming: Lisp/Forte/Erlang

Someone that learns Pascal in 200 Level will most probably struggle with Object Oriented programming in the future and tats before we reach the behemoth that is functional programming, even I still struggle with Forte till this day( I am just beginning to learn Erlang, God help me).

I think we will be dishonest to ourselves if we say that the reason Pascal is taught in our universities is because of the desire to teach the fundamentals of programming rather than the truth, which is, that PASCAL is the language that our lecturers and the computers at their disposal are comfortable with.

This is what I believe in.

leo2009:
hello, programmers, am intrested in desktop development, pls wat does it take me to become a genious in dat aspect,
wat and wat do i need to learn pls, and how do i get ebooks or materials, ,, pls can som1 kindly list out all i need to know before i can call myself a desktop developer, thank you

Now for starters always try to be very explicit! Now when I hear you say 'Desktop development' I will basically assume you mean Screensavers and specialist apps( such as Word and the like). Is that what you meant?
If so, learn C++ for *Nix desktop programming
And learn Visual C++ for Windows Desktop Programming
Maybe Cocoa/Objective C if you want to go the Mac Way.

As for links, please go to:
http://stackoverflow.com/questions/194812/list-of-freely-available-programming-books

It contains links to FREE books to as many programming languages you may need in the next 2/3 decades

wot of a USSD short codes like the ones we use for topping up e.g *123#. How does one go about applying for one ?

These are provided on a network-to-network basis and I don't believe network would easily sell you any access to their USSD Platform ( as this is part of the very core of the network) unless they are strongly associated with your business. In short you go need serious long leg make you get USSD short code for ANY network. SMS Short codes are much more preferable as they are handled differently from USSDs.

damhadji:
Hello people,
can anyone tell me how to acquire a 5 digit SMS shortcode that can be accessed by all gsm suscribers [ eg 35855 for quizline].i have some expensive manuals i'ld like to give to interested nigerian populace.i want the registration for these materials to be via this SMS shortcode. the question is, do i have to go to these gsm service providers for this service or there are software companies that can render these service.please if you have any information, kindly reply this post or mail meat damhadji@yahoo.com.thank you

I am guessing you can implement this by going to Operators as well as getting these short codes from 3rd Parties(I am not sure there are any 3rd parties that provide SMS shortcodes to ALL Networks , most will provide to some but not ALL). Both routes will be costly and will require a fair amount of maintenance ability from yourself but I ma guessing you know that already.

I fear that we ( by 'we' I mean the participants in this post) are over-simplifying the issue/problem with the Nigerian University System (and believe me the problem is with the whole Nigerian University System no just the Computing Science departments). The rot of corruption and the lure of the easy life has eaten into our moral values and absolutely destroyed our Educational system and our University system, being the zenith of said Educational system has felt the most brunt of the devaluation.
The foundation of every University system is the drive for research, to create something out of a single idea, to challenge existing knowledge and establishments by thought-provoking assessments and critique.

But here is the catch, Research of any sort is hard work and for 'Scientific' research (by scientific I mean the creation of new proofs/substances/software/hardware using established norms/works) I fear the work is probably doubled. For a society that seems to fear intellectuals and reward mediocrity, research is damn near impossible.

Why would a Computer Science department be accepting dissertations and courses in BASIC Fortran in 2004?
Why would a Computer Science department be teaching Undergrads the intricacies of creating Databases with MS-Access?
Why would a computer Science graduate only understand how to use MS- Windows?
Why would a Computer Science degree that does not involve Theoretical Computing have 90% Mathematics in the 1st year curriculum?

I know why. It is because it will require a lot more work to do anything else, to do the right thing!

The degree in computer Science in Nigeria is only a reflection of the holy trinity of its participants-- The environment, the students and the lecturers.

I don't really appreciate doing someone elses assignment and I sincerely don't think Nairaland programming section is the bestplace
to come to if you have questions of this sort.

But anyway, a copy of the program you want( or that follows your requirements) can be found here: http://ideone.com/sZSkP

But there 's a catch, Its written in ANSI C, you'll still have to do the conversion to Java.

Best of luck

How far,

Sorry I am just replying this mesage, I have been wishing to help for a while now!

Anyway, if you have already done the promotion of your Windows 2003 server , I assume you already have a domain controller in place.
It is really that simple. To get a deeper insight into how DCs work you wil have to use google. Research in FSMO roles as well. They sould be quite helpful.

The Forward and Reverse DNS zones simply imply the use if names to get IPs( forward) and the use of IPs 2 get names.

You can add the DHCP role using the Add Role Utility in Win 2K3 server but to fully understand it you need to do you research. DHCP for one has serious security implications, anyone can connect to your network and use your resources.

Hope this helps.

Look the battery for my laptop is nearly dead but Sauraus or whatever you call yourself, don't EVER mention Canibus in the same sense as Eminem.

Fact: Eminem thinks Canibus is the greatest rapper alive and had beef with Canibus because when eminem approached Canius to do a track, Can basically treated him like a nobody. This was before Em signed with Dre. Just cos the tables are turned doesn't imply that Em is NOW the better rapper.

Can is as superior to Eminem as Eminem is superior as 50 cent!

Eminem dissed Can? Are u OK? With what 3 bars or something? Have you heard Dr C. PHD on the Mic Club Album?

Have you heard Poet Laureate II? Do you know what it means to rap over 3 different beats from 3 different cultures for 7 minutes and not lose Control.

You don't know nwhat u r talking about!

This is all I have to say,
You can sucks Can PHD-I-C-K!! (That was aimed at Eminem BTW)

And you compare him to Eminem?

Em was also gonna beat Jigga. Jay-Z was never a prolific rapper , he was a brilliant business man! He was not as good as Biggie and Biggie was no where near Rakim or Method Man!

Please compare Canibus to someone on his level like Method Man , GZA , Rakim, Mos Def, Kweli or somebody more respectable. Just cos MTV viewers says Eminem is the best rapper alive doesn't make him so!

If you want more Canibus rhymes just ask!

The rhymes can shut down Nairaland!!!!

That is all!!

The replies in the post have been quite funny!

Do you think every Drill Engineer working on the Bonga Fields enjloys pushing drills all day long? Do you think all the people doing Network Support for Chevron enjoy getting told to defragment hard drives and clean up the internals of the machine?

I doubt it.

But here we are telling this fellow that he should only become a programmer 'if he enjoys programming'( Whatever that means I don't know) in order to avoid the posters original question.

Na wa!

And to the poster, I think what the above were trying to say was, that for the most part, A programmer/Database Administrator gets paid about the same rate as a beggar in VGC which is around 40K a month.

I hope that answers your question.
