Old Paper--The Stability Problem in Feedback Amplifiers
I've posted another old paper on the topic of feedback amplifiers over on
alt.binaries.schematics.electronic It's in 5 pieces. Download the 5 into a temp directory and double click on part 1. As before, if you can't get it, post an email address and I'll send it to you. It's about 3 megabytes, so be sure your email system can accept such a large attachment. You will probably need to use a recent version of Acrobat reader to view it. |

Thank you Phantom. But unfortunately, part 1 is an .EXE ! I don't .exe as I cannot .exe in a Linux box. ( I could using WINE but I don't want to, same as MAC-users ) Besides the OS differences, also Windows users should not be tempted to download something from usenet and then execute ! Even more so when the RAR format can do without ! Robert |

( I could using WINE but I don't want to, same as MAC-users ) If you have a version of WINRAR that will run on a MAC, you can extract the file from the archive without executing the .exe (part 1). I made it self extracting for the convenience of those who don't have WINRAR on their computers. And Windows users who have WINRAR can extract the .pdf file without using the self-extracting feature; they need not execute the .exe. Besides the OS differences, also Windows users should not be tempted to download something from usenet and then execute ! Most Windows users are wise enough by now to know that they should virus check whatever they download before they execute it. Even more so when the RAR format can do without ! Robert As a MAC user, what method would you prefer to break the file into parts for posting? Can you deal with .zip files? |

It's just the .exe that scares me. Robert |

I split the larger one in order to keep the parts less than 1 megabyte each. Some people have complained about binaries over 1 MB on other newsgroups.

Could that have been done by your newsreader? No, how could my newsreader have split it when I was at the downloading end? Neither I nor my newsreader would have any control over the splitting of a binary on the news server. All my newsreader did was to automatically combine the two pieces into a single binary file for me. It would have to have been done by either your newsreader while uploading, or by my ISP after your uploaded file was propagated to it. I know that newsreaders can split files while uploading them, but I don't have a clue whether or not news servers can split the file after it has been up loaded, perhaps we have a usenet expert in the group that knows? I tried a couple of experiments up loading your "Corrective Networks for Feedback Circuits" file to alt.binaries.pictures.radio to see if I could get it there in one piece, unfortunately I found that the splitting mechanism in my newreader won't allow a single encoded file of greater than 10,000 lines which is roughly 0.6 MB as an encoded ASCII file. Unfortunately that isn't big enough to determine if it was likely your newsreader that automatically split up the file when you uploaded it, or if it was the news server used by my ISP that split your file. I split the larger one in order to keep the parts less than 1 megabyte each. Some people have complained about binaries over 1 MB on other newsgroups. I probably should have split the corrective network paper because it's 1.3 MB. Maybe that's why it appeared split to you, perhaps a particular property of your IP/newsreader combination. Yes, the resulting "pdf" file is 1.3 MB, the two ASCII encoded files on the news server my ISP uses were each just a tad short of 1.0 MB each. It didn't appear split to me. That probably depends on how your news reader displays the message list and or how your preferences are set. That is the way to go, why get involved with all these complex windows only formats? I am unaware that RAR is a Windows only format; it's very common on binary newsgroups. Robert says he can deal with it, and he's a Linux user. That may be, I don't know, but why complicate things when the newsreaders already handle this problem without adding an extra layer of formats and conversions?

I have had people complain when I uploaded a multi-megabyte file. There are reasons that the binary newsgroups that have the huge video files split them, one such reason being that some ISP's just won't pass through large files on USENET. It doesn't seem like very much of a complication given the ubiquitous nature of the RAR compression format. It easily obtainable, and as I said it is quite common on many binary groups that offer binaries much larger than a megabyte or two. As an experiment, I'll re-upload the "stability problem" paper all in one chunk and see what happens. Regards, John Byrns |

I didn't say "ALL" newsreaders do it, however Outlook Express does it, does anything else matter? "Does anything else matter?" Are you saying you don't care about the concerns of people who don't use OE? The newsreader I use also does it, as does any other self respecting newsreader. I don't even know what "RAR" means, let alone how to decode it, It's time to learn. RAR is right up there with ZIP in popularity. what was wrong with the old "ZIP" files? I got this comment a few years ago as a result of posting a ZIP file: "When you gonna stop posting these damn .ZIP files?" I'm sure that person could tell you what was wrong with ZIP files. I guess it's not possible to make everybody happy. If you know how to use ZIP, you can learn RAR in a jiffy. When an "RAR" comes along I have to assign the decoding job to my son, otherwise I would have to do without. No you wouldn't. I went to the trouble to make the parts self-extracting so those few people who don't already have WINRAR wouldn't be inconvienenced. After downloading the parts, a single double click retrieves the .pdf file; not really complicated. Or you could get and learn to use WINRAR, just like you learned how to use ZIP. That's what I did the first time I saw a RAR file. Even "ZIP" files sometimes get large enough to require splitting, what keeps an "RAR" from requiring splitting, as one of your recently posted "RAR" files did require? Nothing prevents that. I already said that I probably should have split the "corrective networks" file, which is over a megabyte. If a ZIPed version of some big .pdf file required splitting, then the RARed version would also. RAR isn't intrinsically any better than ZIP. It's just more popular these days, and WINRAR, a utility which encodes and decodes RAR files, is handier to use, which probably accounts for its popularity. "RAR", whatever it is Apparently your son knows what it is; I'm sure he wouldn't mind explaining it to you. doesn't seem to solve the splitting problem at all, It most certainly does solve it. It allows splitting a large file and putting it back together again. it just postpones it a bit, Just because the solution to a problem is postponed doesn't mean that the problem isn't solved. For those people whose newsreaders don't automatically solve the problem, RAR solves it. Of course, any other compression format, such as ZIP, 7ZIP, GZIP, etc., that supports splitting the archive, would also work. I chose RAR because of its popularity. or would that be a kilobyte?
