  1. To reply to this question needs a little history lesson.The first discussion of a packet based network was in the early 1960's and the physical work began in 1969 with the birth of UNIX. This was ARPANET the US Military network and it was designed to be fully redundant and was using 56k leased lines, so in response to the earlier point that there is always a way back to point B is perfectly correct - providing the building still exists....Even what you call today as Voip was running in toll quality in 1973.That said, as things evolved into the true global network we have today it would theoreticaly be possible to bring it down as every network has its weakest link somewhere but we cannot go into detial here for obvious security reasons. Some RFC's are left unpublished for similar security reasons.The Internet itself is mearly the transport mechanism, the physical infrastrucutre if you like and there are many different networks running across it not http and ftp etc which you will be familiar with.
  2. The whole point here is rather quite simple and complex in terms of the market. Current Windows still requires DOS behind the scenes to function. As well as this, both Windows, Linux and now MAC OS rely on either Intel or AMD processors which have to comply with x86 compatibility standards.The x86 is derived from the original 8086 Intel processor which was released 31 years ago and the OS's have to allow for backwards compatibility on the core of the processors.Now, the issue is, if you simply switch to something completely different, you must simply say 'everyone go and buy new computers and replace all your software you've ever bought'.Its a bit like the conundrum of switching off the analogue TV networks - watch your license fee revenues disappear over night....Torvalds did produce a processor some years back which would run pretty much anything with its built in emulation schemes; it was much quicker than most and used less energy, it was just too far ahead of its time and never really took off.On the subject of Vista, it was always just nothing more than ME, a short term taste of things to come.Time will tell which way they all jump....
  3. Heinz Zemanek has put it this way: "Software started with the translation of algebraic formulas into machine code." Thus, the Plankalkul of Konrad Zuse in 1945, the Formelubersetzung of Heinz Rutishauser and of Corrado Bohm in 1951, the Algebraic interpreter of Alick E. Glennie in 1953, the Programming Program of E. Z. Ljubimskii and Sergej Sergeevich Kamynin in 1954 and of Andrei Ershov in 1955 stood at the beginning of software, soon followed by Remington-Rand's Math-Matic (1955) and IBM's Fortran (1956). All these advances were made before the word 'software' came into wider use in 1960, 1961 or 1962. There are over 8,000 programming languages to date and really speaking each one was either designed to solve a particular, handle a particular task in a particular way, maybe created by an individual for one or more of these reasons or by by a committee in which case it was a compromise of many differing opinions.In recent times, it would appear that things are actually going backwards in terms of programming as everything now needs to be complicated and long winded not to mention trying to be all things to all people all of the time. In business for example, it was common place for an engineer to write a program to solve a particular work based task in minutes as opposed to spending days doing it by hand - therefore you didn't buy an off the shelf package which may or may not do the job for you to some degree. I can remeber writing short programs in basic to calculate and graph capicitor discharge cycles for instance, a very simple but effective solution to an otherwise laborious and time consuming task. Another was for calculating and graphing the very complex math for engineering fan design.The first electronic computers were built during world war two at bletchly park in the UK to crack the German Enigma code, one of which has just been re-built as the main attraction at the museum there.Hope this helps in some way.....
  4. In simple terms, ignore what you see from windows - it cannot read the partition information. To access this drive and its files from Windows, you must install Wine or something similar. The Linux partition however should be able to read the Windows one acurately. Windows will say that it is full because it cannot 'see' the thing properly... In other words, when Ubuntu tells you its run out of space then start do do something about it.
  5. Take a look at A-Select it is an open source middleware authentication system for multiple application / resource access. You would link this through Radius / LDAP in your case scenario from what you have explained here.
  6. Sorry I should have said POSIX = any Linux / Unix OS - Many different flavours and variants but basically Berkley 5 compatible on the core. Apples' OSX is indeed POSIX and can therefore through away the junk it doesn't need at that time and will 'call' when it is needed. As for 'plug and play' POSIX systems are now catching up fast as manufacturers are producing drivers in real time along side those 4 Windows, many now also feature auto install just like Windows and self detect network settings etc. However, there should be no reason why you cannot run OSX on a PC provided it isn't loaded with those 'windows only devices' problem just as you can run windows on an x86 MAC.
  7. Indeed your math is OK, provided the voltage is fixed then amps x voltage = watts. Modern devices such as drives have come along way in a short time so far as power consumption is concerned with most now using high efficiency motors and CMOS.The other most important trick to efficiency is cooling in a balanced manner; the more amps a device draws, especialy processors etc the hotter they run and consequently the less efficient they become. Idealy, you should draw fresh air at the front bottom say, and draw the hot at the top rear as circulation is one of the key factors rather than just sucking hot air out. Efficient cooling will also reduce the curent draw for a given load...
  8. As we have a serious mosquito problem where we live here in southern Botswana this topic is of particular interest. However, the most usefull site I ever found was this one https://entomology.ca.uky.edu/ef003 I guess with any thing of this nature then it becomes subjective, for instance, in Colonial days it was noted that burning certain types of wood in the braziers outside at night kept the mosquitos at bay - try finding enough of stuff round here now...... If there were an effective way of solving the outdoor problem I would be first to buy....
  9. Well, this is certainly a refreshing post, a few more like it please....Now just a few comments. Firstly, I noticed the reference to Hitler and the third Reich, it should, however, be clearly understood that this all stemmed from the first Reich of the 1860's with particular reference to Namibia and the first death camps. Hitler was indoctrinated by the generals of this period in his youth which is how the later atrocities came into being. In the interim, the Germans had re-written their history books to hide these earlier times of which they were ashammed.I cannot see the theory of the rise and fall of empires on a proportionate time scale to be correct as I can't think of any other which would match. The British Empire which was purely based upon economics and business in that developing the nations of the empire drove the industry at home as well as world markets in staple products such as tea, rubber and sugar. It only took less than fifty years to collapse due to the two world wars.....I am, however curios as to WHY the technology of ancient empires always died along side the empire itself though... Does anyone have theories as to why this is? After all, does ot make sense that the next civilisation doesn't need the same level of sanitation or water for instance?
  10. The best option I found by far was to scrap off Microsoft Office and change to Open Office suite. Simply click on the button and it will generate a PDF of the file your working on perfectly. Handles all MS files from all versions as well as save as such.You can also export powerpoint as flash to put them in your website which is most useful.
  11. Every 'POSIX' O/S i.e. Linux, Unix, Mac OSX etc. have a complimentary 'heart' if you like which is to be Berkley 5 compatible - a bit like Windows is x86 compatible, which is its biggest problem but thats another story... 'POSIX' have the ability to only load drivers which are needed at that moment in time and disguard them afterwards, unlike Windows which loads them all at boot time and keeps them (used or not) until you shut down. Also, with 'POSIX' systems, you have the ability to 'build' the kernal to yor own requirements and your specific system. An example of this would be, you have a fully featured processor with every concievable option built in - and more importantly - wired, but you only need your system for power 3d artwork; so, you re-build the kernal so that it maximises everything to do with YOUR processor AND 3d graphics and leave out the rest such as multimedia extensions etc. In other words, you can remove the clutter to gain maximum performance for what YOU need your system for.
  12. In reality it is the other way around. The reason for the 'bang' is not the speed of the projectile but the fact of which on an automatic weapon the breach opens at the immediate point of firing, thus, although you have the suppressor (silencer) on one end, the sound will simply travel out the other as the case is ejected and the new round loaded. In a revolver, the breach is not open thus the suppressor (silencer) deadens the sound dramitcally.
  13. First of all you should determine 'which' password is being spoken about as there are several levels of password, bios itself and system for instance. On most all systems the BIOS password is simply reset by a jumper on the system board; however, the system password is not. Not only this, but it is NOT stored in the BIOS chip, this requires either the correct password or the master password applied at factory level. Too obtain the master password requires you have the original sales receipt or you have to have a re-placement chip which requires specialist equipment in the soldering dept......
  14. Not quite as the program would be 'running' from system A where it is installed and simply displayed and controlled from system B. If it were like you say then there would be no point to a network and servers as all systems would be running independent installations and no shared data - accounts packages for instance or databases like this forum......
  15. Basically it should be no different from sharing programs on any other network. You should make sure your drive and folder 'share' permissions are set correctly on each system. In particular the one containing the programn we will call this system A. You must ensure you are able to to access the main drive containing the program - an example would be c:\programfiles\photoshop - but only an example as your setup may be different. In simple terms you looking to share photoshop.exe or whatever it is called. You then create a shortcut to this on system B - the one you wish to run the program on in the same way you would create in normal circumstanes just on a different desktop. The only issue you may have here is setting the permissions in XP which can be a pain at the best of times. Also, check how you set the network up. In general it is better to do so manually than use the home network wizard especialy if you different versions of windows on each machine.
