- In MacApp we do a similar thing, except critical requests are called
- "temporary", and non-critical requests "permanent". This reflects
- whether or not the memory is for the user's document, and cannot be
- reclaimed later.
-
- Temporary (critical) memory consists of code segments, defproc
- resources, packages, etc. By default all requests are temporary (ie,
- critical), although the programmer can change the state of the flag as
- needed. We also provide a call NewPermHandle to allocate a permanent
- handle.
-

-
- In MacApp, the programmer can specify the size of the temporary and
- permanent reserves. The permanent reserve is just a last chance piece
- of memory that the grow zone proc will release if all else fails. When
- this memory is gone, then memory is really low and MacApp will put up a
- message telling the user this (overridable of course). The size of this
- reserve is usually only 4-10K.
-
- The temporary reserve is more interesting. The programmer sets this
- size based on the maximum amount of temporary memory the program will
- need at any time. MacApp will ensure that this amount of memory is
- available. We add up the currently loaded segments, defprocs, etc.; if
- the sum is less than the reserve we allocate a handle to make up the
- difference. (This is so memory is not wasted trying to maintain the
- reserve.)
-
- If the programmers sets the temporary reserve correctly, then the
- program cannot bomb because a code segment, package, etc. cannot be
- loaded.
-

-
- This approach will work, but it makes it difficult to change the
- program's segmentation without having to change the code. Also, in the
- case of MacApp, we could not know how the final program would be
- segmented, since we can't know what code the developer will be writing.
-
- In MacApp, you specify the name of the segments that form the maximum
- code working set, as well as an absolute number to add in. This
- information is in resources so that it can be changed easily. (The
- MacApp debugger helps you determine which segments comprise the maximum
- working set.) The idea here is that the maximum working set might
- change in value, but the segments that make up the working set should be
- consistent.
-
- The programmer can also change the size of these reserves
- programmatically.
-
- The only kind of preflighting we do in MacApp is when opening a DA. We
- make sure that there is enough permanent memory for the DRVR resource,
- and then we open the desk accessory with the temporary flag on. This
- helps ensure that the DA won't bomb when opening (in case it doesn't
- check its memory allocations).
-
- After the DA is opened, we check to see if our guaranteed temporary
- reserve has been exhausted. If so, then we immediately close the DA and
- report an error. (This assumes that the DA cleans up after itself, but
- there is nothing an application can do with such unfriendly DAs.)
-
- Region operations that occur in the normal course of events
- (invalidating a window) are considered temporary, and the temporary
- reserve should handle them. This would only be a problem if regions
- were being used at the time when the maximum code working set was
- loaded.
-
- MacApp also unloads all code segments each time through the event loop,
- although the programmer can mark a segment as resident and then it won't
- be unloaded. Unloaded segments stay in memory in case they are needed
- again.
-
- This memory management architecture seems to work very well. It has the
- advantage that it is generic, and doesn't have to recoded for each
- application. The programmer only has to plug in the specific parameters
- of the application. Before MacApp was released, we tested our memory
- management by having the testing group stress test one of our sample
- programs as if it was a product.

-
- The other week I was running MPW 2.02 under Apple System 5.0 (Finder
- only, not Multifinder) on my Mac II, when the cursor changed to a
- tolerable line drawing of a bulldozer and a lot of disc activity began.
- This situation continued for a minute or so, whereupon the cursor
- returned to its usual arrow shape and MPW resumed normal operation. I
- have never seen the like before or since.
-
- It could have been a virus doing something wicked, but it has been long
- enough (several weeks, several hundred hours of active on-time) with no
- obvious evidence of disaster, that I doubt it.
-
- If I had to make a guess, I would say that either MPW or the Finder had
- decided to do a thorough heap-compaction and was writing out a large
- temporary file to disc as part of the process; the bulldozer cursor
- seems appropriate for pushing a big jumbled heap around, and duplicating
- the heap to disc is a fairly common trick in garbage-collection
- algorithms. However, I could not find any obvious reference to this
- behavior in any of my manuals. (On the other hand, considering the size
- of the MPW manuals and of _Inside_ _Macintosh_, I may well have missed
- something.)

- Ok, I'm not an economic or political expert (or an expert of any
- kind :-) but I think that even if this pact isn't the best solution,
- something has to be done to protect US manufacturers, and I don't think
- that just scrapping the pact is a solution.
- Japanese and other asian chip producers can currently produce chips
- at prices significantly less than US producers, and US producers are
- having a hard time competing. This is just great for consumers and
- computer and perhipheral manufacturers, but if it keeps up, US chip
- producers will have to move to something else or fold. Many people I
- know say that the Japanese are obviously doing something right, and if
- US producers can't do the same then they should get out. In my opinion,
- I think that the fact that the asian countries have a much cheaper labor
- force is a significant factor. US producers obviously can't just cut
- their employees salaries in half, so some would say that they should get
- out. Ok, so we lose the IC industry, big deal. In the southeast the
- textile industry (which is the south's major industry) is taking a
- beating from Korean imports. If they can't compete, let them fold.
- Everyone knows that the US car manufactures are having touble competing
- with Japanese imports and therefore make poorer quality cars. Well, if
- they can't hack it, they should get out too. Asian computer and
- perhipheral manufacturers are already beginning to overtake the market.
- Bye bye US manufacturers. Hmmm, we seem to be running out of
- industries. Oh well, as long as we consumers are getting cheap
- products, no problem. Ooops, we seem to be losing jobs and can't afford
- these products anymore, how'd that happen?
-
- Also I seem to remember reading in NewsWeek that last spring,
- Japanese companies were accused of dumping chips on the US market at
- prices lower than it cost the companies to produce them. The only
- reason that I've ever heard for this kind of illegal activity is to
- eliminate compitition. I've also read that the Japanese economy and
- infrastructure is stacked highly against imports, and that US imports

-
- While I agree with you that the Asian countries have a cheaper labor
- force and that their economies are sometimes stacked against imports
- (especially Japan's), I cannot agree that that is the whole problem.
- Ask not what they are doing that is underhanded, as what we are doing
- that is wrong (so that we can correct it). I generally do not favor
- protectionist policies.
-
- Take the automobile industry as an example. In the begining, the
- Japanese gained a foothold because their cars were cheaper than American
- built ones. Then, we fell further behind during the energy crisis
- because our cars were less fuel efficient. Over the years, Japanese
- cars have become more luxurious, until now they rival some American Cars
- in that regard. However, with the rising Yen, those cars have become
- more expensive. But, because of the image that the American car buyer
- has of Japanese quality, Japanese cars still sell well. (However, I
- think this is changing.)
-
- Basically, there are two differences between "us" and "them" that are
- important here. First, the Japanese seem to be more responsive to
- changes in the market, and they seem to be able to change quicker. This
- is not a function of worker's salaries. Second, and more important, the
- Japanese as a society seem more willing to support the long-term
- technological research that is needed to make products in a more
- efficient manner (or at all, in some cases such as VCRs). (You should
- watch a tape of the NOVA that was on last night about superconductors,
- they made some good points about this.)
-
- We Americans seem to do better at inventing new things, but the Japanese
- are better at spending the time needed to develop these ideas into
- marketable products. Again, this has nothing to do with worker's
- salaries.
-
- I could go on about the problem of the Japanese owning businesses in
- this country. There is also the problem of worker education (or lack
- thereof). These are problems that need to be addressed, but they are
- peripheral to this discussion.
-
- It all boils down to this: In order that both societies should prosper,
- we need to become more like the Japanese and the Japanese need to become
- more like us. We need to fund that long-term development research, make
- sure that our work force is better educated (to keep up with changing
- technology in the workplace). And, American consumers have to change
- their attitude about foriegn products. (A little attitude change is
- better than a lot of trade legislation.) (Presumably a change is
- attitude will bring about a change is behaviour. ie: we'll buy more
- domestic goods.) American companies overseas should know more about
- those markets. Trying to sell the Japanese a product that sells well in
- this country without modification is often a fatal mistake.
-
- The Japanese, on the other hand, should change their behaviour about
- imports. They _should_ open up their markets to foriengers. (On the
- other hand, American companies should learn about the sometimes baffling
- Japanese system of business dealings, after all, they had to learn ours
- to be a success here.)
-
- The bottom line is that pointing the finger at Japan and crying foul is
- incorrect, useless and possibly fatal.

- Can any Mac wizard shed some light on a programming problem I'm having?
- My edit record (TERec) seems to completely loose track of the number of

- TEInsert. The number of lines that nLines jumps by doesn't seem to

- with TEScroll after each ($0D) is inserted but this seems unrelated.
- Calling TECalText fixes the edit record with nLines returning to

-
- I'll bet you're using a Macintosh SE. On an SE, the lineStarts array
- will be calculated incorrectly (or sometimes the system will crash) when
- all of the following conditions hold:
-
- _TEInsert is called;
- the inserted text ends in a space;
- selEnd = teLength;
- after the text has been inserted, the (garbage) byte following the
- newly inserted text in RAM happens to contain a carriage return.
-
- Neither the Macintosh Plus nor the Macintosh II have this bug.
-
- The bug lies in the routine whose address is stored at $07fc. The ninth
- through eleventh instructions in that routine are:
-
- cmpi.b #$0d,0(a0,d0.w)
- bne.s ...
- addq.w #1,d0
-
- If you change the add instruction to a no-op, your bug will disappear.
- (You may have created a different bug because this undoubtedly disables
- a minor feature of TextEdit, but the new bug seems much less serious
- than the old.)
-
- I hope this helps. The bug was reported to Apple on 10 February 1988.

-
- Ok Folks, we've been evaluating the new IISC laserwriter, and found some
- things that seem to be real problems. The first problem ocurrs when
- printing a Microsoft Excel spreadsheet. The time it takes to print this
- spread sheet seems to vary from a low of 2.5 minutes to a high of over
- 35. Can anyone suggest any reason why there should be the amount of
- variation in the printing of the same document. The spread sheet is one
- page, printed landscape mode, uses only the Times font.
-
- The second problem is with a Microsoft Word (3.0) document. This
- document has two columns, is in Times, with screen dumps included with
- 1/4 inch column spacing, and 1/2 inch margins all around. When printed
- on the SC it seems to expand the margins so that the right column is
- pushed off the edge of the page. The inter-columnar (1/4 inch ) is
- enlarged to greater than 1/4 inch, and no amount of spacing adjustment
- seems to solve the problem. Not even setting the columnar spacing to
- negative values (ie -0.25 inches gives more than +0.5 inch spacing
- between columns). Switching measurments to picas instead of inches gives

- Has anyone else out there used the SC, have you noticed these or any
- other problems with the printer? What's going on here. Would someone
- from Apple care to comment?

- I have experienced the same problem as the original poster, except that
- instead of being limited to the shift key, it also sometimes happens
- with the control key or the option key. I do not have a copy of Easy
- Access in my System Folder, so I believe the problem must be coming from
- another source. Any suggestions would be greatly appreciated.

- A friend of mine is interested in acquiring some 3.5-inch,
- double-density, double-sided floppy disks for use on an Apple Macintosh.
- He wants them to be made in the USA by a U.S.-based company, and with
- a life-time guarantee.
-
- Scotch is the only brand he knows that corresponds to these
- specifications. Are there any other such companies? Where can Scotch
- or any other brand of these floppies be purchased, either through mail
- order or in the Boston area? Please e-mail responses.

- On page 15 of the A/UX System Overview manual, it states: "Another
- important function of the kernel is interprocess commnuication (IPC).
- A/UX fully supports the System V Release 2 IPC mechanisms." ... "Signals
- are another form of UNIX interprocess communication." ... "A/UX supports
- both System V and BSD signals"
-
-
- Additionally, in the A/UX Release notes, Version 1.0, on page 1-2: "A/UX
- supports two different versions of signals: the standard V.2 and the
- 4.2 reliable signals. To use 4.2 signals in a program, issue a call to
- the set42sig routine before issuing any calls to the signal function."
- ... "The signal-handler setting is not inherited across an exec call,
- although job control and process grjoups are available to shell
- programs."
