@all
sorry guys, it seems i am not in the same ream with you guys. i migth have been living in the fourth dimension world which you guys fails to see. anyway, i promise not to make any contributions again that can bring about any spontaneous reaction with you guys. i pray you all to stay blessed and keep up your dreams and aspirations in engineering. the future of this country in engineering depends on you guys and many aspiring guys out there, bye for now.[color=#990000][/color]

before you can say, you need to understant a little bit of history in programming.
programming lang, strating with fortran was developed to enable the computer to be used as a reusable calculator. this makes sence since you dont have to keep swithing the computer everytime to do the same job. in those days , a lot of lang were developed, each with is distint adv and disavantages. basic became a very popular lang then because it is simple to learn and prog. many proffesional programmers normally encounter problems programming long and structured programs. thus after two two or three initial lang., the c lang was developed . it is i true structured lang and thus became very popular among proffessional programmers. most operating systems are still written in c lang. in the late 70s and earlly 80s, the object oriented method of programming became the defacto. in other to still enjoy the power of c, c# was developed. it is a c progarmming lang with object oriented prog. about the early 90s, microsoft develop vb to be the graphical users interface verison of basic lang. thus continued with the popularity of basic. java was then developed i the early 90s to be a net version of c#. thus write once , use anywhere gave it taht popuparity it enjoys. vb, then stands to the challange and develope vb.net, the net version of vb. to know which is  easier depends on your knowlege of the parent lang

@ ajanlekoko
i am sorry to you and everybody if i am creating unnecessary distraction in the house. my write up on who is an engineer and who a technician/ technologist is is in respond to the matter raised by sylink 1 where he said that people schould not waste time looking for admission in the university, but can proceed to the polytechnic. i am only trying to enligthing him and any other person that the university curriculum is different from that of a polytechnic. university trains and produces engineers while polytechnic trains and produces technologists/technicians.
my write up on software for engineers is in responce to question raised by oyb and i coute ", Autocad is a truly fantastic tool, but most of us use it as a substitute for a drawing board. , ", ", the real problem with learning autocad is that if you don't learn it in a professional environment, you will have a lousy foundation, and do so many things wrong - and you won't realize this. the architectural drafter in my office is a prime example. the man considers himself to be an autocad guru, but he is unable to do more than use autocad as an electronic drawing board. as i said, if you understand and really utilize autocad, there is no limit to how much you can speed up your work process. try to understand the use of layers, blocks and attributes. these are essential to competent/professional use of autocad." and the question posted @oyb ", whats the diff btw design and drafting? (as relates to autocad) , "
i have been in the computing arena for a while. i used the opporunity to answer the question raised and try to educate some other proffessionals on how to use the computer to improve their productivity.
i had classified these uses into 4 groups. the first i said which is programming is mostly used by engineers as a reusable calulator. to work out a particular formular such as v= u+at, just load up the formular, slot in your values and your answer is on your desktop.
the second which is cad is what is generally not understood by people. this is the question neototse asked oyb which many people can not still figures out. computer aided designs CAD are basically the computer versions of the drawing board with som additional capabilities which are not possible on ordinary drawing boards. these capabilities includes referrence to an ext file which could be another drawing files, database files, programing lang, or even offices app such as word, excel, power pt,e.t.c.
the last which is the simulation softwares are the real design tools. it simulates the real life conditions after the relevant datas which guides the properties of what is to be fed are inputed into the computer. for instant, a simulatition software could tells us what will be the I-V xteristic properties of a transistor say for 0.01% doping and 0.02% doping. thus the engineer can see in forhand what will happen to his circuit if he decided to use anyone. these simulation software would have been preprogrammed to behave or display certain I-V properties for a particular doping values. this saves the eng a lot of time and makes him to see in forhand what will happen to his design before production. the simulation softwares output is independed on the capabilty of the engineer, supposing in getting the final value of my output i need to say consider a potential well value and used it for my final result. if i did not considered this due to ommition or ignorant, the final output will not be what it is meant to be. thus the outcome of such softwares are independent of you. all you need to do is just to slot in your values and the real life situation of what will be wiil appear on your computer.
why i voted for simulation software as of engineering is this. the first plane was manufactured by the Wright Brotherswithout any design. this they can do because they understand the mechanisms of flying. this is technology and not engineering. a lot of people still do this mistake. they cannot figure out the differrent between technology and engineering. they felt making this to work is engineering, but it is not. the act of building the palne itself is craftmanship. knowing how the plane works and the mechanisms which does what in the plane is technology.but the enginnering itself involves the complex calculations of and in every components of the plane. it should be notted that we are still on the verge of unlocking nature to know the secrets of engineering. this is the reason why many advance countries are making research to know more about these secrets so as to have a better design. it should be notted that the internet which we are enjoying today is as a result of the american military wanting to coallate the results of these test from all its research universities and centres. the blue bird plane is one of such results. it is a spie plane that was design during the cold war era to spy on the ussr terrances in case of eventuallity wars. these planes flies in the upper atmosphere and thus non dectectable by radar systems. the formulations of these designs are kept secret. thus maybe it could be added to our future school theises if man sees that their would be more wars and thus an aeroplane can access these formulations into their future designs. it schould be notted that the camera in phones e.t.c we used freely today were once classified informations in the cold war eras. nowadays, such principles have been added to the sch curriculums. thus you all wiil agrre with me that eng is dynamic. the main difference between we and the and people of the iron age is the amount of information that is available to us. thanks to our libraries which stores those formulations for they generations yet to come. every year, knowledge is been aded and a lot more is needed to be cosidered in design. thus a simulation software can do more to us than we can at this moment.

ayo fayose was reported this morning to have escape arrest after granting a t.v interview. my people, what is happening in ekiti and nigeria?

well, for the jobs to be readily available, we need more industries. what is bad if the government can start a space race program, it will also absorbed some of the unemployed youths of the streets. what about a defence program? all these and others are what keeps these foreign countries going. our government should take a leave from these other countries and do something now.[color=#006600][/color]

AutoCAD is a CAD (Computer Aided Design) software application for 2D and 3D design and drafting, developed and sold by Autodesk, Inc. Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC. Most CAD software at the time ran on graphics terminals connected to mainframe computers or mini-computers.

In earlier releases, AutoCAD used primitive entities — such as lines, polylines, circles, arcs, and text — as the foundation for more complex objects. Since the mid-1990s, AutoCAD has supported custom objects through its C++ API. Modern AutoCAD includes a full set of basic solid modeling and 3D tools. With the release of AutoCAD 2007 came improved 3D modeling functionality, which meant better navigation when working in 3D. Moreover, it became easier to edit 3D models. The mental ray engine was included in rendering, it was now possible to do quality renderings. AutoCAD 2010 introduced parametric functionality and mesh modeling.

AutoCAD supports a number of application programming interfaces (APIs) for customization and automation. These include AutoLISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.

AutoCAD's native file format, DWG, and to a lesser extent, its interchange file format, DXF, have become de facto standards for CAD data interoperability. AutoCAD in recent years has included support for DWF, a format developed and promoted by Autodesk for publishing CAD data. In 2006, Autodesk estimated the number of active DWG files to be in excess of one billion. In the past, Autodesk has estimated the total number of DWG files in existence to be more than three billion.

AutoCAD currently runs exclusively on Microsoft Windows desktop operating systems. Versions for Unix and Mac OS were released in the 1980s and 1990s, but these were later dropped. AutoCAD can run on an emulator or compatibility layer like VMware Workstation or Wine, albeit subject to various performance issues that can often arise when working with 3D objects or large drawings.

not a bad idea if its intention is to save cost, but they should note that a polytechnic is not the same as a university. polytechnic is a practical and technology school, while a [color=#770077][/color]university is a school for philantropics.

the use of computers for engineers can be classified into 4 major category
1, programming e.g basic, fortran, c ,c++, java e.t.c. these enables the engineer to do calculations of the formulars he has programmed into the computer
2, computer aided design (CAD) e.g autocad, cadkey, archicad, generic cad e.t.c these enables the engineer to use the computer as a drafting machine. because it can represent the design project before production/construction, we can use CAD as a modelling maching. this aslo enables cad integareted with presentation managers to be used for presentations at seminars, classrooms and industries. automation makes CAD to be used for animation. CAD software also enables external ref. for specifications, costing and notes.
3, mathematical softwares and spreed sheets. e.g. mathscad, mathematical, m.s excel e.t.c. these enables the engineer to do complex mathematical calculations such as integratin, differntiation, differential equ. e.t.c . graphical representaion of results are possible. many mathematical softwares solve problems when you type the question the way you write them in your notebooks
4, simulation softwares e.g algol,pSPICE, e.t.c these are the last and most recent use of computers for engineers. it is still undergoing evolution unlike many other applications that have taking their standards. it tends to integrates every aspect of known topics into the design. since the knowledge of engineering is still evolving, it implies that the factors considered into the desing and thus the software are still elvoving. according to morse law, the amount of information available to mankind doubles say every 10 or 15 years. since all factors are important when considering design, i am voting for this software as the future of engineering. our knowledge of engineering is limited to what we learn in school. it should not be suprising that what we study for waec was what you need to know to be a graduate or even a proffesor many hundred years ago. the future generation may as well religate our current university curriculum as school cert. syllabus, thanks to the amount of infomation that must be known to them then. since we have limited capabilities and may ommit certain consideration during design due to omission, ignorant, e.t.c, i think all engineers should start learning simulation software because the outcome have little effect on your personal capabilities.

which is the best software to work with in nigeria?

@oyb

oyb:
@Ajanlekoko
i use visio, but mostly for organograms

its guys in IT/networking that typically go into visio as a drafting/design tool - the MS factor (imho) so much of the environment is based off microsoft apps, so its a natural transition

@neototse,

the fundamental diff btw designing and drafting would be something like this

where i worked (CA) the drafters would print xrefed architectural drawings(these are drawings with all info not relevant to the design process removed) and pass these to us.
one would markup the design on the hard copies, hand these back to the drafters, and they would draft the drawings ie simply draw what they saw

in the event that a person with design knowledge is doing the work directly, without first marking up on paper, that is designing

sort of like typing - you write something on a sheet and hand it over to a typist to type - thats copy typing - you do it yourself, thats er . . .don't know what they call it

what happened is that our resident architectural drafter did the building drawings. i took these, xrefed them, and did the electrical designs

Autocad is a truly fantastic tool, but most of us use it as a substitute for a drawing board. for instance , i have cad routines that can generate schedules of items in my drawing.

autocad ties in with practically any engineering discipline, but yur use of it would depend on what you do. an architect is unlikely to use/customize autocad the way a mechanical engineer would.

if you were involved in designing power protection schemes, you might use autocad to prepare these. there's something i remember from my days at jiyoda. part of the power calculations involve a mohrs circle

this used to be done with a protractor , compass , pencil and paper, but one day i realized that it could be done in cad. and it would be much faster once a template had been created. they're still doing that now.

the real problem with learning autocad is that if you don't learn it in a professional environment, you will have a lousy foundation, and do so many things wrong - and you won't realize this. the architectural drafter in my office is a prime example. the man considers himself to be an autocad guru, but he is unable to do more than use autocad as an electronic drawing board. as i said, if you understand and really utilize autocad, there is no limit to how much you can speed up your work process. try to understand the use of layers, blocks and attributes. these are essential to competent/professional use of autocad.

if you hit up rapidlibrary or filestube with 'autocad for dummies' or 'autocad bible' you will get links to autocad ebooks on rapidshare. type in autocad 2010, and you'll get links to autocad 2010, and so on.

so great website

google lynn allen, melanie perry, cadtutor, www.theswamp.org, ellenfinkentsen ; these are blogs/ cad forums

nice drawings, keep it up. the use of computer in engineering dates back with programming. the ease with which it offers the engineer to do its job contributed to the polularity of the computer which we have today since there are little or no applications for the computer, such as word processor, spreedsheets, multimedia e.t.c,
i will generally classify the use of computers for engineers into 4 major category
1, programming e.g basic, fortran, c ,c++, java e.t.c. these enables the engineer to do calculations of the formulars he has programmed into the computer

i have started a forum under programming tittled NIGERIAN ENGINEERS AND INFORMATION TECHNOLOGY. in this forum, we will be able to discuss softwares, their merits, limitations and what tools we engineers need to equiped ourselfs with. everybody in the house is invited for contributions, advices and education

@sylink 1
mind you and everybody in the house. there is a difference between a polytechnic and a university. a graduate of university in the engineering field has underdone a different curriculum trainning from that which comes out from the polytechnic. according to the NSE  and COREN, these are the classifications/ qualifications
1, engineer, bsc and above
2, technologist, hnd
3, technician, ond
4, craftmen, nabtech, waec tech and other techical cert.
5, artician, practitionls who have learnt the trade with many years of experience
everybody has its own job to do. in western world, this disparity does not exist because the need of everybodies job is specified. in nigeria however, many of the people do not really knows who is who. in a nut shell, an engineer designs, and most cases supervies a project. they also uses time study and work study to increase production, reduces cost and thus are more of management in the eng field. they also discover new methods of achieving the same goal or attaining a better goal. a technologist is somebody that understand the current methodlogy. he works based on the engineers specification and supervises the craftmen and technicians. this is the reason why he must have years of experience which is the reason you must do your IT before doing your hnd. a tecnician and craftmen are practical people. they are the people you see on the field of engineering carring out one task or the other. so please dont advice people wrongly to change their mind to do what they do not want to do. rather, educate them. if you like to be practical, poly is the palce to be, but for the calculation and researchers, go to the university. you failing jamb this year only tells you to stepup against next year

well, i like your call towards developing our local software. this is the reason i started a forum titled nigerian engineers and information technology. nigeria must change. we have to change.

@kaceei
i want you to know that no course been offered in engineering is of any irrelevance. those who designed the courses knew why they did. they are what is expected of you to know as an engineer. engineering goes beyond the basic working principles which is what the polytechnic schemes and syllabus are expected to address. egineering involves knowing natural phenonenoms in your fields and advances mathematical solutions to problems. you are bored with those courses because that is not what your mind is prepared for and really, they may not be any relevance in our society because we do not involve ourselfs with designs of systems from the scracth. if you do, then you will applied all the laplace, bessel functions and forier series of this world. then you will apreciate courses that you had offered in school. this is the reason why i have said that do we really need engineers in our society? what many engineers practice are what is meant for technicians and your certificate only add to your cv which garantee you other irrelevant jobs such as your current banking jobs. even in the computer and IT fields, you do not really need to be an eng to take them, but you eng cet garantee you the job.

@fireman
it is not residual magnetism that exist in the tv, rather it is residual static electricity which is of several thousand of voltage.
@alobfadii
i will advice you to stick to what you have got. i made the same mistake many years ago. i was undergoing my industrial educational training with a multinational company. at this place, i was exposed to what engineering is all about, but disatisfied with the way things are done because many projects were not really designed based on engineering calculations i.e stress of the materials, factor of safety e.t.c. rather it is sad to even know that many of the people working in their engineering dept are not engineers. even, only few have technical certificates which is what we obtain after our trainning. rather, they employ anybody into their dept of engineering and requires him to services their plants which are not even covered up with working drawings. this makes repair and maintanance very difficult and unless you are familiar with that particular plants, you cannot do anything to it. this is what they see as thier working experience. the sectional head of the a/c and refrigiration dept then when i was there does not even have a pry 6 cert talkless of interpreting the carnot cycles and the rest which are occurring in such reversible heat engines. even the so called foreign expertrates which is the overall head of the engineering sections in the factory had just a technical cert. i was caugth between taking a desion on whether to stay or proceed to have my university education. i decided to move on. today, i am regretting this action because financially, i would have been better than i am now. i discovered that it is money that matters in this country rather than what you have to offer intelectually. this is one reason why i had said that do we really need to produce engineers in this country when they are of little or no relevants to our economy. engineers working in the banking sectors are much more better than practising engineers like us. so bro, do not leave what you have now unless there is an offer which is greater than present salary you are receiving.

we do not even need to be conected to the net to have a good programed software. the program could reside in your desktop

you guys may feel i am not of any relevant to this topic, but i am really saying the truth. i am one who thinks very much ahead of my time. i had loved to study electronics from my childhood, much to the fact that i love movies so much and had wanted to receive a clear signal from LTV8 of old which shows nice action pack movies every weekend in the early 80's before their station got burnt. during this period , i was still in my primary school and i engauge myself in a lot of discussion with my friends on the working principles of the television. we construct areas with fluoriscent bulbs and at many occassions, i sneek to open the back of our television to see the working principles of the television. this made me to always update my scientific knowledge and by the time i was taking my jss3 exams, i already understand at least 50% of the working principle. i continued learning more about this principle and electronics in general. i registered for electronics and applied electricity in waec, coming out with a3 (b3) in both subjects without ever attending a class in electronics just for once in my life. i will thank my contact with introtech and re interpretations of physics phenonenom for this. even the population of us who took the exam in this subjects were even less than 100 in the whole of lagos state. even now it is lowere as less than 30 sat for it in lagos in 2008. then i had the ambition of constructing my tv, and recording tv signals on cassette tapes. i studied physics with electronics. i only discovered that most of our school curricullum do not explain the working principles of many of this devices which is even the first step for any meaningful engineerings. rather, we are concern with advance mathematic such as laplace, bessel function, forier series e.t.c. although, this mathematics solve the mathematical operation of the current and the voltages in the circuit, but many students cannot figure this out and are not even aware that these mathematics are applicable to a particular block in a system. to make matter worse, modern televisions are processed by softwares using microprocessor. thus, even the technicians who were of little relevants before will be knocked out of the system. lets just wait till 2012 when nigeria's airwave will go all digital. for us to be relevant and marketable, we should design, and dictates the pace of what is in our society, not what is imported into or society. an average consumer cares less, and thus if we want to take the job, we must leave to our expectations as nigerian engineers for the nigerians society of all our tioling migth be in vain. the digital age was born when the american engineers saw the treat posed on them and their economy when japanise first develope the HDTV technology in the 60's but now all those are now history,

hello guys, i would have advised that nigerain universities should stop offering courses in ee because they are required in limited number and have little relevance in our modern society. mosty hit is the electronics which the semiconductor chips have made there relevant useless.

well, there is a lot. we engineers here in nigeria are the ones clamoring for a chage. who do we expect to come and change things for us. is it the whites/ a forum like this is meant to enligthing ourself in the field. as for me, i am despirate to have a lot of things change. thats why i want to incorprorate information technology into engineering in this country. this forum is for people with like minds. people who are in the the engineering field, programming and information technology field, or both. this forum will enable us to share ideas and profer solutions

of what use will this information week be to nigerians engineers who wants to develop software solutions for their various disciplines?[/color][color=#550000]

i am not out to drag views with any body. after all every body is entitled to its own opinion ( even with couples and twins) generally i am not moved by niger stuff and even many new foreign films. i only watch what will while away my time and caugth my attension. i love quality and creativity which many of nigerian movies lack due to technical capability and fundings, but at least try to patronise few of "tin wa tin wa" our own. i am happy and will be happy to see great things "videos" comes out of this country. that is my view and no more[color=#770077][/color]

what are our young dynamic programmers doing to salvage nigeria software industry?

i only wanted a compiler to play with programs i studied and used in school during my undergraduate years. thats why i need basic fortan and its compatriot compilers. thanks.[color=#000099][/color]

of what importance is computer to modern enginers. its like we learn so much formulars in school, but in the real world, we tends to neglects all those standardisations. i will give kudos to the civil engineers and our building engineeers for adopting at least a larger percentage of what they learn in thier proffessional fields. as for the mechcanical and the chemical engineers, zero is their case. i think this is the time we change or turn things around[color=#006600][/color]

well, the bible itself have solved the problem. its says do not judge for thou will be judged. so therefore it is not rigth for anyone to accused pastor chris or anyone that he is a false prothet even though these were to be through. rather, the bible itself has said it that on the last days many false prophet will arise. so why are you people so mavelled? even if pastor chris were false, some peoples faith migth be strengted through that and they make heaven. thats the altimate. as for the pastor, he is only accountable to God and not man, so leave him alone to continue his ministry. god sees all. even when elli and his sons were bad, they were still the priest of isreal interceding for the people of God( the isrealite) until God cuts them fromthe face of the earth. the bible has said , torch not my annoiting and do my prophet no harm . therefore, it is a sin to call any man of god fake no matter if its true or not. remember what david did to the man who claim to kill saul despite the fact that god himself has rejected saul.[color=#000099][/color]

such, given one its project is not ok, but someone can guide you through, supplys you some materials and give you some giudelines and advice. this could save you a lot of time[color=#770077][/color]

movies in present nigeria are no movies but junks except from gurus like tunde kelani and few others who sit down, think, and spend alot of money and time producing a movie. jenifa, however been one of these junks can really be a good way to waste time behind the screen. at least for the yoruba
