Do you really know what's on your computer? If you're the average citizen, then there's a high probability that your computer has been or will be compromised at some point. "Hello Mr. Smith, we have some bad news for you. After forensic examination of your hard drive, we found evidence of money laundering, child pornography, and several thousand instances of copyright violation. But don't worry. We're going to make you an offer you can't refuse.
I respond: Please clarify this: you should insert the words" MS operating system" some where in the paragraph.
The problem is that IBM and Intel/AMD do things fundementally different inside their system(s). I am not sure I can explain entirely how INTEL/AMD work. IBM's high speed buffer there are "things" that go on that help out the execution of the instruction before it gets to the point of execution. There is also something else that IBM does is predictive branching and operand decoding and instruction look ahead work that actually stream lines the execution. BTW their code *DOES* work countless billions times a day. IBM also has a way to serialize storage so only one person (program) can update the same storage location at a time. I do not know if INTEL can do that or not but if they don't I would not trust them at all. Many a time I had to shoot a bug in user code that didn't allow for that and its not fun.
While I was around in that time frame, my memory is a little different (but could be the same). S/38 was an outshoot of IBM's FS system. (Future System). I think I know one person that worked on it and he may be retired, like me. IBM's FS was (if stories are to be belived) however somewhere along the line reality at the time said CPU's weren't even close to be capable of running it. My memory says it was in the 70's and even IBM's fastest CPU was not fast enough at the time. I have heard stories about it and not knowing anything first hand I would suggest you find an IBM old timer and ask him/her what killed it off.
FYI, if the application was not designed to use the correct time then of course the entire system has to be IPL'd. Granted that people rarely if ever worried about the clock, it only came important when databases became involved and a point in time was really needed. Or in some small number of cases (mostly financial) had to care about it. If the system is running batch then no need to IPL until a point in time that is convienent to everyone can be done. CSA creap is almost a thing in the past, yes it still happens but if can be planned for. Almost all vendors have fixed that issue although new code does creap into the area. IBM has addressed this in several areas and you can not allow a vendor to get CSA if you choose not to allow it. Anytime there is a system area that people think it would be great to use there has to be careful design of it to make sure when you are done with it you free it, if you cannot guarentee it then you should not be using it. CSA is a limited system resource not to be used at will. IBM will tell you tough luck as if you are responsible for using it you must free it when you are done with it.
I'm betting the code used on these z196 systems is multi-threaded. Shit, if you're paying hundreds of thousands of dollars per CPU you can afford some top notch programmers.
Actually I think this mainframe is for getting the last little bit of performance out of thirty year old cobol code. And the original top notch programmers are long dead.
I wish you would take a refresher code as to what the new Z/os systems can do. I think you would be amazed, items such as being capable of running UNIX type system while still run MVS. No emulators all the code is done by the OS (on a single system no real hypervisor either) The hypervisor is only used to partition off different OS's. No I am not talking about VM the IBM hypervisor is buried in the firmware. The workload manager (new with Z/os) had its ancestor that worked very well workload manager is able to fine tune the work distribution a lot better.
But the main thing is that not all programs are multi-threaded, and a program with a single thread can only run on one processor. So yeah, GHz are still useful. Maybe for large single-thread batch processing - which is the kind of thing a mainframe would do.
I guess you have not worked on any modern IBM mainframe. They are a different beast that say 15 years ago. All modern online systems can and do take advantage of what you call threads but the current people call something else entirely. While it may be true that some batch processing mostly run under one "thread" (to use your term) they can/do take advantage of multiple CPU's. If they are halfway modernized I suspect they can fully take of multple CPU's. There is a *LOT* of running one job on mutiple cpu's, mind you its under the covers and the user doesn't really see it, it does happen. As for the interactive side (developement) it was designed from day 1 to run on multple cpu's concurently with IBM's workload management (all Z/os systems run it to some extent or other) was designed to get work out as fast as the system can supply the cpu & storage That is one of the major reasons why Z/os can run at 100 percent cpu utilization 24 hours 7 days a week and pump out more work than most (all?) systems. With the new systems I understand that System Z systems can be gotten with terrabytes of storage. Now I/O is as fast (or faster) than any other system that is available. At one time the biggest bottleneck was I/O and with advances in the OS and faster controllers and large capacity hard drives it gets the work out faster and cheaper than any other PC system out there. I do not work for IBM I just work on the Z/os and find it steps above any other PC system. The cloud that is the current buzzword in the PC world has been doable for say 10 years (at least) its called GDPS and the systems can be quite a distance from any data center. I wouldn't mind if people would learn the whole story.
I am guessing here, but it would be reasonable that once a jury heard that the feds refused to place charges they would vote for acquittal. Rightly or wrong that how jurors I believe would react. I do not know if its allowed in the courtroom to say that the feds refused to prosecute but if it is its dead.
Well what is "fun" to one is not fun to another. But one software author has a YAHOO group and asks everyone to test out his beta's. I am a member and the product is well known for its versatility and the feature number of options that fill probably 50 screens worth of some really obscure options. The guy quickly investigates any reports and fixes them before general release. Since everyone is eager to find bugs the email list is lively and can get a bit esoteric as you have to be an expert in the field to understand some of the options. The beta I installed tonight will b e about the 20th so far this year. I find some(bugs) from time to time and I really test out his product and I do find some bizarre issues.
The author does not speak great English and that adds to the fun(?).

Not to go off on too much of a tangent here but it is relevant. Victimless crimes (like porn, prostitution etc) are *NEVER* victimless. Ask any policemen who has been on the street for more than a few years. There is a pattern that becomes too clear of people that were victims of say their parents are harmed mentally and they end up repeating (in some form) of what their parents (or relatives or who ever). Children of prostitutes become prostitutes in later life. Just like gang bangers had parents that were gangsters (or at least major law breakers). Sure there are the odd few that do not fit into the above but the majority do. *IF* you really want crime to go down you need to get the people out of the contact and put them in a stable area and this is not a short term thing you need 20-50 years of no contact so the cycle can be broken. In other words there is no quick fix and will only work in a LONG term solution.
Finally!!! About 4 years ago I opened an account and then started to receive all sort of SPAM. I tried to figure out how to delete it and just gave up trying. I sent a help request to "someone" and never got back a response. I was relling a friend about this 2-3 months ago and he produced instructions that were well lets say complicated. At LAST!!! I was able to delete my account and I have not looked back. A POX on all the jerk companies that think everyone has a face book account.
Its probably due to MS's lacking the ability to combat the IPAD and IPHONE from Apple. MS is sucking up all the available oxygen to try and come up with a real product for anything.
No, it's not sterile. Farmers aren't idiots and they refused to buy sterile crops.
Well, technically, Monsanto does not allow farmers to buy GM seed at all. Seed is essentially leased and final product must be sold after harvest. Attempts to use the seed outside of the terms of the contract signed with Monsanto will lead to finding yourself in court.
Or in some cases murdered or forced out of their farms and other heavy handed nasty things that xxxxxxxxx has done. There are some interesting documentary on what they have done. To be honest it sounds like Al Capone.
Inflation (for the most part) is not caused by taxation. From my understanding inflation is caused by an in balance in the budget. Essentially you are spending more than you take in. The people who believe taxation is the root of all evil are living in a fairy land. Countries like Monaco and others are not large and complex societies. They tend to be small and have budget surpluses, the populations are so small that they can pay for many things like retirement and road taxes from the surplus. Sooner or later when the population expands (although thats hard to do in the Cayman islands and Monaco) so it is unlikely to happen any time soon. On the other had you have places like China with very high population and the government is very poor so they tend not to care about people dying to soon so they do not need a social network. When you come down to it the difference of the the two is that people in smaller societies care more for their neighbors whereas people in high density type situations (over population) they tend to think that people are truly expendable.
Secret Police??? We have the CIA/FBI/Pentagon looking for the creator of Wikileaks we don't need no stinkin' secret police.
There is also the side issue of who really is telling the truth. The people in the US presume reporter to be telling the truth, which is not always the case in the US and foreign countries. So just because someone uploads a "story" doesn't make it true. In order to trace it back to the originator there has to be some sort of way to do this, otherwise you will have governments (including ours) uploading reported "true" stories and there is no way to check to see who is actually doing so. I am not sure how WIKILEAKS handles this but they apparently do. However in this case it is a little more sensitive as (false) stories could really hurt a government. While tha same maybe true for WIKILEAKS (unless it is a real juicy piece) it probably will embarrass a government not topple it.
I thought a bit about buying an IPAD and put it off but one evening I decided what the heck buy one. The IPAD arrived about 3 weeks after I bought it (long story deleted). So it showed up at my house one day and there were no instructions on what to do with it. There was a 3X3 leaflet but I just assumed it was the packing slip. There were no clear cut instructions on how to connect it up to anything! After looking around and turning the box upside down I decided o call a friend who is MAC inclined and asked what I was supposed to do with the damn thing. He walked me through the plugs and what they were for and I asked why this wasn't in the package. I guess he said it should be self describing???!!! I finally found that 3X3 piece of paper and it wasn't a packing slip but the instructions. Only problem was that I swear they were in 3 point font. Did Apple send along a magnifying glass? NO. I guess they expected you to do a Vulcan mind meld.
Much to my surprise when I plugged the IPAD in to my computer up pops a message that IPAD needs 1.5 or higher. I thought wait a minute I found quite a few IPAD advertisements that just had MACOSX. Well I have MACOSX so why doesn't it work? I figured ahah APPLE F****d up. So I went to the Apple site and kept drilling down and I finally found it yes it needs 1.5 or higher. This did me zero good. So since I will not *EVER* upgrade passed 1.4.xx I am screwed. I put the IPAD down for 2 weeks until I could schedule a friend to come over so I could activate the damn piece of junk.
A week goes by and I finally get the think semi working. By that I have to wait for him to come over so I can d/l any books etc I need. I feel I got screwed over by Apple. The order form should have spelled out that you need 1.5 (or higher). So its gathering dust. I played with it for 4 hours and I am not impressed especially when doing email on YAHOO its difficult to say the least. The keyboard sucks missing keys and on and on.
I would never buy one if you have any physical issues (like poor eyesight) and to send out the IPAD without a stylus how stupid can Apple get?
Sorry but I have been in the programming field for 40+ years and have only vaguely heard of the guy. There are only a few people I remember for example the inventor of COBOL and of course the micro computer people. Like Steve Jobs and the other one. I do not spend time looking at the history (while it might be remotely interesting) it really had nothing to do with the job I performed and frankly what they might have done 50+ years ago what ever they did, they only have their name in this day and age. There are many more current people that have contributed immense amounts of knowledge to todays coders than most (if not all) of the grand daddies of computers.
Computers now days are on the orders of magnitude more sophisticated than the in the days when these people were around. While they may have contributed some important first "rules" or compilers or "laws", I think in general most of the people would be considered out of tune in todays computing world.
Maybe not all over the place but several companies I have worked in it seems that way. I know its no PC but H1B people seem to come in just after the 45th birthday. That is bad enough but when the H1B people have a know it all attitude and they (sometimes) think their way is better and they juggle process's around and that bolloxes up stuff that they have no knowledge of and they think they can fix that as well and by the time they are done they have made a shambles of the entire system. They were told before doing anything like what they did is to consult the documentation. I guess they never listen. This has been observed at three companies essentially the same circumstances (but different results but in all three it took days to recover)

I won't visit it either until Cheney is locked up or in a casket buried 6 feet (at least) under.
Then MS will charge for it. Dumbing down is natural for MS. This is just one more step towards windows domination.
BTW maybe that might be good for people with pace makers in them. The surgeon doesn't need a PHD in electrical science so he can't charge more D.
They probably should get the same lawyers that justified torture as a way to get information.
