IBM Test dumps
My profession has had some pleasing facet-outcomes on my lifestyles. within the starting, computer systems might best be mindful upper case and in consequence I acquired in the dependancy of printing, in higher case. I just about at all times print, and infrequently print in lessen case. My handwriting is complex to examine and to do! In high faculty I took a typing path, one of the few classes I nonetheless use each day. however the keypunches of the era forced me to desert the use of the appropriate shift key, as a result of a keypunch best had a left shift key, and a appropriate un-shift key. The Cyber consoles had re-organized the digits, destroying my already-minimal capacity to the touch classification digits.
through the years, a considerable number of attitudes have existed between the technical group of workers and administration. in the early Seventies, administration was itself relatively technical, and a superb rapport existed between the employers and personnel. The assistant directors would do programming and hardware construction! As time went on, and administration grew to become extra detached from the work being executed by way of the group of workers, this perspective became somewhat antagonistic every now and then as a result of administration may also now not be as privy to what the "worker's" definitely do. An example from February 1995 of this degradation got here from the division director in a note saying a video-taped panel making its visions familiar on future computing:
"I have a video of a trigger current concerns forum. The title is "Seeing higher education in the year 2020." I have considered it. It lasts 78 minutes. a bit of tedious within the core, it does tackle many concerns relative to information know-how and its impact on greater education. furthermore, the participants are "precise people" like Presidents, Provosts and school, now not desktop techies."
aside from the ridiculous fact that "real americans," or anybody, can predict the state of computing 25 years into the future, please observe that the technical body of workers aren't real people. (became this an attempt at humor? if so, it did not come across that means, as it appears to be too near the perceived attitudes).
For one other illustration of the rift between administration and employees, seek advice from the story prior on write-conserving a 9-tune tape by means of slapping red stickers everywhere the write-ring slot. in this case it is a knowledge rift, demonstrating the inability of technical talents of some managers. in the event that they cannot consider technical work, how can they manage it? incredibly, it can be performed (I've viewed it), however doesn't appear to take place very commonly.
maybe we're lucky, however to my knowlege we've got had simplest just a few examples of "bad" personnel. The ideal (?) instance was an operator from both the late Philco or early Sigma period (I feel it changed into early 1970). on the time, instructors would mark a scholar's grade for a class on a laptop card. The playing cards had been then punched via their keypunch operators (and established), then fed into the equipment for sorting and final grading. An operator curiously turned into no longer satisfied with his grade, and managed to find his card and alter it by pasting a piece of tape over the gap and re-punched it with an "A". The instructor didn't observe this when he posted the grades on his door (he got a sheet from Registration & records, possibly bring to a halt the SSNs, and taped it to his door) but one other student saw the grade and complained. The teacher insisted their operator had not been given an "A" but there it become on the roster. ultimately the card turned into pulled, the tape changed into noticed and the operator dismissed. In an additional case an operator turned into the use of the Cyber console "H" display to check the user validation file. i thought this become fairly artful, and painless since the passwords were no longer stored in clear text, but administration decided to dump him.
an extended-standing difficulty in computing is the repeated failure of companies to "get it appropriate". during this illustration, tape drives and drivers. even with the finished dominance of 1/2-inch tape for over twenty years, each and every time they changed vendors I found problems and shortcomings. With the Sigma, I've already described the fiasco of the poor design of their 7-music power that caused operating device crashes. They also made the regular blunder of disallowing arbitrarily gigantic block sizes. after they acquired the Cybers, I ran a examine with Sigma-written tapes containing each block dimension from 1 byte to 32K bytes and found that NOS would mis-report block sizes that have been a certain assorted of 512 CM phrases. On their VAX eleven/785, the TU80 tape force would mis-document some small block sizes up to about 14 bytes, an issue for which DEC had a primary fix that they in no way became into an ECO. They felt it became most effective worth setting up on drives if the consumer complained, in spite of the fact that the pressure turned into on a service contract. VMS can't examine arbitrarily colossal blocks. It additionally claims to ignore all small blocks smaller than 14 bytes, which is a lie (no complaint except that the documentation is wrong). although, it'll refuse to put in writing blocks smaller than 14 bytes with the effect that they can read old NOS tapes however can not copy them! VMS' BACKUP utility loves to write its own labels in its place of letting the working equipment do it (very unhealthy information), and on OpenVMS Alpha 6.1 botched the labels by some means on continuation reels so that VMS might not take note it as an ANSI tape set. (This changed into been fastened in VMS 6.2).
I've in no way seen a dealer that protected a constructive tape copying utility within the operating system. All utilities have been particular-aim, corresponding to being useful for labeled tapes only, or unlabeled tapes with fixed data. The large difficulty in tape copying is figuring out when to stop. If the tape is ANSI labeled and the utility is aware of this, it's neatly defined. but if the tape is unlabeled, of unknown structure and only a bunch of blocks and tape marks, the handiest convention worth bringing up as a de-facto regular is to cease when two tape marks in a row are found. Most utilities are not that smart.
one of the vital very worst tapes I ever saw, when it comes to structure, turned into the source tape for Versatec application for the Sigma. It become unlabeled, and truly began with a double tape mark (almost a regularly occurring signal that no extra legitimate assistance follows). each file changed into separated by means of a double tape mark, except the ultimate file become effortlessly adopted by means of clean tape in its place of even a single tape mark.
there is additionally the problem of multi-reel tape units. If ANSI labeled, things are pretty clean except for opting for what the "next" tape is if you do not already understand in develop (NOS had a fix for this, that worked lots of the time). but there aren't any requirements for unlabeled tape units, and every time I hear of such, I get upset. as an example, NOS could be informed to change reels on unlabeled tape units in a single of 3 ways:
When the reflective marker is found throughout a write, abandon the write, change reels, then write the block again.
When the reflective marker is found right through a write, complete the write, change reels.
When the reflective marker is discovered all through a write, finished the write, notify the program, and hold writing unless a write-eof is requested by the program. Then change reels.
Of route, in case you did not know the way the tape changed into written, you doubtless couldn't study it correctly. (This applied to NOS "Stranger" tapes, now not ANSI or "internal" tapes).
a different huge blunder the industry made, aside from starting out with octal computers as an alternative of hexadecimal, became to adopt a 7-bit conversation code for storage of eight-bit bytes. This ended in all styles of problems, similar to CDC claiming they supported "8 bit ASCII." a lot of carriers performed hints with the eighth bit, similar to leaving it zero, leaving it 1, the use of 0 or 1 interchangeably, or the use of it to outline an incompatible 2nd set of 128 characters (e.g. MS/DOS, DEC Multinational). Then once more, IBM cannot even standardize its personal 8-bit EBCDIC code. IBM will define a code of X'nn' as, say, a vertical bar (shift-Y on a keypunch), except that on some particular mannequin of printer with some specific print chain it's going to print as an alternative as every other persona. look at an IBM code chart and you'll discover things like three different underscore characters, and several different codes that have different portraits counting on the equipment. finally, there may be the subject of non-translatable characters between ASCII and EBCDIC, such as EBCDIC's cent sign.
speaking of ASCII, a connected snafu is the "tab" personality. Its use become at first to shop area in data, however seriously yet silently assumes selected tab settings. On the Sigma, terminals (i.e. TTY 33) had no real tabs, so it turned into all achieved in software. The default mode changed into that when a user hit a tab key, the tty driver would determine how many areas were required to get to the next tab cease, and would ship that many spaces to each the terminal, and the calling software program. therefore, tabs had been by no means actually kept inside the file (I consider they known as this "space insertion mode"). Now, in 1995, the issue nevertheless persists. Many computing device functions will keep tabs within the file, but if you lift this file to VMS (or Unix?) it will now not screen appropriately since the tab settings are different (and there is no means for the file to declare its assumptions). Even inside VMS itself, lines will monitor in another way in some editors (e.g. EDT in line mode vs EDT in screen mode) since the tabs don't seem to be handled appropriately. moral: For Pete's sake, don't use tabs!
companies retain releasing editors that can not edit an arbitrarily-large file. in many circumstances, the limits had been considered as "within your means" at the time the utility changed into written, but shoppers and/or storage advances right away overcame it. On the Sigma, the editor would deal with 16K lines max if I be aware. This was a captivating editor since the information have been keyed (ISAM) with the important thing being the line number (CP-V keyed data stored the important thing fully separately from the records, unlike most other implementations) however the key become too brief to handle big information. but it surely did imply that no "work" file became obligatory, nor huge gobs of reminiscence. On the Cybers, XEDIT "pretty much" did it appropriate but in a number of locations used 17-bit "B" registers for the line number and consequently was restrained to 128K traces. a popular patch among NOS consumers become to repair XEDIT to make use of 60-bit "A" registers in its place, doing away with that limit. Later, CDC's Full screen Editor (FSE) could handle huge files but took a extremely long term to examine them in and build a piece file first. In VMS, EDT will wreck if the work file is over 64K blocks, and TPU will break if the file is larger than the consumer's working set limit. Most DOS and computer editors will also fail if the file being edited exceeds 640K or another reminiscence restrict. I regularly hit this the usage of the Solaris vi editor with either "Tmp file too huge" or "Out of register space (ugh)" or "Line too long".
Many carriers/applications cannot seem to contend with empty info. On probably the most early Sigma operating systems (BTM?) the model utility considered a file of zero size to be an error. while this *may* be the case, it depends on what's occurring, but the utility certainly can not make that decision. a number of sites had to beat up on XDS to persuade them that sorting an empty file made perfectly first rate sense. just supply me an output file with all zero information sorted so as; in other phrases, create an empty output file if the enter is empty. Let the programmer decide even if or not it's a problem! This came to intellect simply today (1995), 25 years later, noting that the MXRN news reader aborts if the input information.rc file has zero statistics!
probably the most amusing fiascos to monitor within the long term, is the steady flip-flopping on the subject of aborting jobs/strategies. in the early days if a job ran away, you rebooted the equipment. The OS individuals soon gave us a means to abort jobs, either from the operator console or, finally, from a person terminal. almost as rapidly the clients demanded a way to kill-proof their jobs, either absolutely or to at the least enable the software to "trap" such exceptions and do whatever thing changed into fundamental (which in some situations become to proceed on with the project in progress). subsequent, the OS individuals gave us a method to *really* kill a process in addition to a means to basically ask for demise. a pretty good example is VMS, with the often-misunderstood difference between handle-C (please die) and handle-Y (I demand that you simply die). Of route, the users then demanded a means to capture handle-Y and do with it what they wished. Unix allows ten distinctive tiers of kill signals (the remaining stage being uncatchable), and NOS would unconditionally kill a technique that had already been killed as soon as. In VMS, a privileged manner can set just a little that says "do not kill me ever, no count what" and i lately had one of these method (allotted Transaction supervisor) grasp and forestall the system from shutting down appropriately. On a VMSNET newsgroup, somebody became asking a way to kill a kill-proof manner. or not it's been a constant combat between the "I have to no longer be killed" and the "I need to be capable of kill" factions. Of course neither is inherently right or incorrect. but it has been unique to observe issues swing backward and forward, with further and further layers of kill and no-kill. and naturally the computer makers have re-found the whole subject from scratch in preference to pay attention to adventure.
Mainframes are lifeless. Small systems will take over. I've heard this when you consider that the PDP-eleven become brought, and that i nonetheless do not believe it. certainly the small desk-appropriate system has made a big affect, chiefly if dropped from a height. however despite 15+ years of being informed the dinosaurs of computing are outdated, they proceed to reside. just these days (March 7 1995) I study that in 1994, IBM's sales of MVS techniques grew by 40%. relatively lively for a corpse. As I said, small techniques have their place. That place is growing, and of course modern-day small gadget has more storage and compute energy than the mainframes of just a few years ago. however there are projects that readily cannot be completed on a household appliance, corresponding to payroll for a college or registration/information. at the least no longer yet. My existing
chortle is evaluating tentative plans for a laptop file server for college students. A multi-processor equipment with gobs of memory, very fast tape power for backups, and many gigabytes of disk. an awful lot greater than the klunky historic mainframe, with its dual processors, gobs of memory, IBM 3480-fashion tape drives, and 27 gigabytes of disk, right? Even when administration tries to make their own predictions come true, "mainframe" use continues to climb.
Yet a further normal mistake, or possibly incorrect perspective, is the "commonplace error." An utility or gadget yields an error message, however the dealer or provider says this is typical. Baloney. other than being a nuisance, the standard Error tends to produce the "wolf" effect, desensitizing the viewer from true errors. it be unprofessional and cheesy. My favourite illustration become their Digital 7620 Alpha equipment. in case you enter check at the console prompt it might run a bunch of self-diagnostics, then exit. however upon exit the console utility will either function accurately, dangle, or explode with a "catastrophic failure" (their phrase, not mine). since the diagnostics themselves completed normally, this error changed into of little concern to Digital. In other phrases, a "common catastrophic failure." Sheesh.
hey, i'm starting to sound like Andy Rooney.
a lack of common terminal behavior additionally plagued the industry, though with home windows taking on, this is less vital. illustration: some terminals wrap long strains, some truncate lengthy lines, many can also be set one way or an additional. Some courses predict a truncating terminal, some predict a wrapping terminal. Some even set the terminal the way it expects, then leaves it set that way when it exits. Why is that this crucial? instance: In VMS mail, users here commonly typed message devoid of ever hitting the Return key since the terminal/emulator they are the use of happens to wrap long lines, so the consumer thinks WYSIWYG and continues typing. but in fact VMS regarded it a single lengthy line because the wrapping turned into finished by using the terminal, no longer VMS or Mail, and when the user hits persona 512 the road receives truncated with an error message. This confusion may be averted by using now not wrapping.
providers often supply you techniques of setting whatever like a technique attribute, however no manner of examining it. I bear in mind in NOS it become trivial to set a user Job identify (UJN) but darn close impossible to assess its latest environment. There are a few things in VMS that you can SET however no longer reveal.
before they began getting Digital-suitable terminals, my journey in this specific focus become with terminals that both wrapped or didn't. Then when they got precise DEC-appropriate ones, i was further aggravated to find that VT-terminals would position the cursor at column eighty after you typed the 79th persona, and would then *go away it there* on proper of the eightieth after you typed *that* (so how do you distinguish a 79-character line from an 80-personality line that ends with a blank?). here's a fascinating feature but advanced the concern of supporting distinctive terminal forms on NOS.
For decades, they simply *had* to standardize on terminals that had been suitable with the common Lear-Siegler ADM-1, because the AMS techniques had been programmed to operate with these terminals. This excluded the Digital VT collection, a great deal to the chagrin of practically all and sundry else. When WHECN turned into fashioned, they also adopted the AMS techniques as a typical, and WHECN repeatedly pressured the concern of a compatible terminal class for both them and UW, even after UW shut down the final AMS. a brilliant example of the tail wagging the dog. handiest when they bought the VAXcluster, and PCs grew to become plentiful with Kermit's VT-one hundred emulator, and UW/WHECN divorced every other, might they standardize on a common terminal.
within the enviornment of significant computing, UW has seldom been a contender (reckoning on whether you accept as true with a Cyber 760 a serious number cruncher, which it was simply barely in 1979 once they acquired it). a number of hand-waving has been accomplished through directors, often claiming that point on supercomputers was freely purchasable at different sites, which is/became no longer the case. One well-positioned source claims that Cray analysis offered UW one among their techniques, but it changed into rejected as a result of "too many strings connected." another sign of this is UW's Institute for Scientific Computing. I contend the mere existence of this community shows that their Division is never serving a vast sufficient segment of UW's population, but others have disagreed. As desktop computing vigor has increased, this has practically turn into a non-difficulty. They look infatuated with networking, email, and word processing, however there are still those that use computer systems for computing.
A second illustration of now not meeting campus wants, as a minimum in a really good enviornment, is the attempted startup of a separate company referred to as GRIP. This changed into the brainchild of the VP for research, who desired a carrier firm dedicated to computing device photos. however this community turned into presupposed to be "self ample" though I by no means got a precise definition of what this intended. The implication, as above, is that the imperative computing division wasn't doing its job when it comes to serving the campus. lamentably the VP in question "quit" (i.e. acquired canned) early in the task, which then quickly grew to become into a pictures lab for a few researchers in preference to a campus-large service center.
I on occasion wonder how management views me, especially my zeal for element (for which i was as soon as criticized on an annual assessment). currently I found out a retiree's account, where the retiree had died. This introduced up the question of how to get rid of the user's files, if for example a department or relative requested entry, so it changed into handed on to administration for a correct pronouncement. I might basically hear them asserting "most effective Kirkpatrick would be concerned about useless clients."
administration, whereas that means neatly, has now and again gotten technical jargon fouled up. This as a minimum gives us with some humor. One grownup is at all times involved about "increasing response time" in its place of decreasing (improving) it. lately they got excited about a computerized tuition suggestions kiosk, with its "touch tone display." One supervisor tried to work out how large a application may be, with the aid of dividing the page file measurement by way of the variety of approved users. Of path they frequently hear about "native enviornment LANs."
we've time and again terminated really expert services as a result of they were simplest used through a small number of clients. while i will be able to be aware the energy of this argument, chiefly if dictated via economics, it issues me. I as soon as advised a director that they may keep a *lot* of funds by means of not providing any features in any respect, if funds is the difficulty. however a school needs to cater to greater than simply the calls for of the bulk. for instance, returned in 1970 there have been just a few hundred individuals using their computers to do computing; in 1995 there are over ten thousand using them for electronic mail and composing unnecessary memos, and a couple of hundred people nevertheless the use of computer systems to do computing; should they hence inform the latter to wander away because they're in the minority? The remaining thing they need to do is strive for mediocrity.
Time: no one seems to keep in mind time, and the distinctions between local time, general Coordinated Time (UTC), and international Atomic Time (TAI). people get dumbfounded in the event you mention that UTC can have leap seconds introduced or subtracted up to twice a year; I understand the POSIX official stance is that this readily doesn't turn up (little doubt as a result of they could not agree on exactly how a POSIX-compliant system may still handle soar seconds). leap seconds are any such mysterious pain that some have argued they shouldn't happen at all, or they should still simplest take place once each decade (if they can not deal with it twice a 12 months and get it appropriate, what makes them suppose it should be handled accurately as soon as a decade?). At subject are functions and operating techniques where the human coders have not regarded time accurately, who write issues like "make xyz turn up at 23:59" without realizing that 23:59 could now not truly occur because a bad start second may cause UTC to bounce from 23:58 to 00:00, and different equivalent mistakes. if you want whatever to happen one second before date change, you should definitely be in a position to code it that method devoid of assuming that 23:59 is that time. and do not neglect that with positive jump seconds, the time might progress from 23:59 to 23:60 to 00:00. Then there are the darn legislators who in 2005 changed when daylight saving time begins and ends, constructive in 2007. how many computerized methods will malfunction because the historical timezone suggestions had been challenging-coded?
spam: everyone has certain-fire ideas on the way to cease junk mail, but most of them conveniently do not make lots of sense. for instance, the greet-pause feature of sendmail will reject connections from senders/servers if they try to ship e mail earlier than the receiving gadget ship an intentionally-delayed greeting. the belief is that spammers use impatient software, and that non-spammers use polite RFC-compliant utility. Of path here's not authentic but out of the lots of connections they reject, there is no manner to know what number of would had been unsolicited mail and the way many don't seem to be. The identical is true for IP-tackle blacklisting; UW isn't a huge spammer yet they appear to land on black lists from time to time and despite being falsely focused, they gleefully became on their own feature to reject email from black-listed sites. There changed into some type of idea that involved having each person put in a unique DNS entry so that others would recognize you might be good enough however this on no account looks to have gotten very a long way because, of route, no longer everyone bought into the thought and spammers can run their personal DNS servers. and so on.
Disappearing error messages: Idiots who write error messages on the reveal then clear the monitor before that you can read them. for this reason i am often hostile to clearing a display for any motive. Of direction here i am talking about terminal emulators for the most half however the same factor has been followed as an example in Solaris installation home windows, where I as soon as had the set up comprehensive and clear the monitor in spite of unrecoverable CD-ROM examine mistakes, getting rid of the evidence that anything else went incorrect not to mention what it turned into that went wrong. The same issue can turn up on sun programs when OBP detects a problem then clears the screen when the windowing software starts; if this is before syslogd begins, you can also no longer even be aware of that the rest is amiss.
Metric: When the metric device became invented, all styles of new screw sizes have been invented. no longer only did these range from the old "English" sizes, they even determined to invert pitch, going from threads-per-unit-length to length-per-thread. Duh. but then they come up with standard sizes which are *basically* identical to the older sizes, in order that you cannot even come to a decision at times no matter if you are preserving a metric screw or a common screw. So what does this ought to do with computing? an awful lot if you simply mangled a metric threaded hole in a rack since you put a 1/four-inch screw into it. Or if you have a type of old stupid sun SBUS cover plates with screws that might possibly be 2-fifty six or they should be would becould very well be 2.5mm. Of route the bloody French anticipated the planet would go metric just because they're the French, and many of the planet did apart from the dumb old US. Sigh. Time for me to take a stress capsule.
