Re: PIK microcontroller development issues
Hi, all, Thanks to Tom, Chit, and g. I have to go get my Christmas lights down and stowed, clean up some place for relatives to stay, and then I'll get back on this. I didn't even thing to look for another mailing list, DUHHH!!! I'll try all the hints, gather more information and subscribe to the FEL list as soon as my melons (honey dos) are complete. For the non-americans, honeydew is a delicious melon. The pun is that wives give us a list of things to do, Honey, do this please?

PIK microcontroller development issues
to discover any or all of the following: A. shared object file name B. install paths C. errors being generated if they don's show up in the gpsim windows (clearly the cause of not quoting error messages here other than the one that gpsim couldn't find the processor which appears in two different forms depending on how I invoke it). 2. A process to get gpsim working on Fedora (this seems to be a F11 issue because I have had little luck finding solutions on the web despite working on this for weeks.) 3. Once past 1 and 2, integrating the works for F11. Maybe I can get some of you interested in neat microcontroller programming. These little mcpus are really quite powerful and neat for all kinds of jobs.

Re: man 3 switch
and truncation errors can occur at intervals of 38, 72 and 134 if I remember correctly, at least something like these intervals where the rounding function will produce one number in one implementation and a different number in another. I have had people argue with me about my code being wrong, even after I would write a test case and show them that the problem wasn't the code, but rather the choice of compiler and its resultant choice of floating point implementation. It gets more arcane with chained calculations. Each time you multiply two numbers together, there is an associated rounding error. But it is generally quite small, and in most processors moved out a few bits at the stated resolution. However a write to memory forces the truncation at the stated accuracy, and then it begins to affect really complex algorithms, such as the FFT or some arc calculation programs that use squares and square roots. Or in some graphics calculations where the round off and truncation errors lead to additional distortion in the periphery of the visual field due to the combination of those errors and the planarity (sp?) error of presenting a spherical result on a flat plane. i.e. a lens product on a monitor. Maybe the photons particles don't perform that task well either. But how would you categorize all these different effects, provide examples, show the results in the several cases and also hopefully add some guidance (such as man pages do) for the combinatorial effects?

Re: Music Appreciation teaching program ??
. If you want to know why airplanes fail, examine the outliers, both those that never fail and those that fail more often or more catastrophically. Once this makes it into mainstream, many things will change for the better if people stick to analyzing all aspects of all the raw data. This is why it is impossible to say that formal training is better than adhoc knowledge, and is the prime reason that both formal training and informal training are necessary and valuable to all professions. In other words we are all have something to share. Just my opinion.

The Beatles never knew how to read music. Just imagine how much better they could have been! ;-) Sorry, couldn't resist. Yes, there's a lot of talented people without formal training. But I tend to be more impressed by those with it. And they're certainly more able to work with other trained musicians, as they know how tell each other what needs doing. More, um, thingy, doesn't work too well. But I find it hard to believe that anyone actually doesn't like classical music if they like other forms of music. It is truly universal. Many do, without realising it, as it's used all over the place (cartoons, commercials, etc.). Though I've had many a good piece of music ruined for me, now, as I cannot avoid seeing Bugs Bunny and Elmer Fudd in my mind's eye while hearing the piece. Some are actively prejudiced against it. A friend's teenage son was trawling through the ring tones on his phone, commenting on ones he liked and disliked. He liked quite a few classical ones, but the moment I enlightened him, he deleted them. I caught him singing some music from a couple of operas, once or twice, but he had no idea. He'd heard them on TV somewhere, but no clue as to what they really were. Others will never get to hear it, because of the prejudices of those around them who will pick the music that's heard. They moment they hear it, they turn off or go away. Several composers were child prodigies, and gifted from birth. Their music is heard around the world, and admired. And yes, many received classical training once their capabilities were known, but their talent was present first, and in some cases, I believe schools take on such talent to further their own resume's. Its not that training doesn't matter, as much as the fact that the environment one chooses changes ones perspective of language and its usage to communicate those wants needs and desires you speak of. Yet music is a language of its own. As are most endeavors in life. One need not have formal training to succeed, but one must have access to the accumulated knowledge. Societies of elitists often try to corral the knowledge, and keep it captive so that they can continue to be rare and demand great sums for their skills, while many equally or possibly even better talents never get the chance. Programmers are kept from arising by the ACM as much as they are enabled by it. Electronics engineers are kept from mutual knowledge by the IEEE, as much as the members benefit from it. And yes, I do know the costs associated with maintaining the libraries (although given computers and disk sizes, the ability to maintain large libraries and search through them is falling exponentially faster than the law of gravity would accelerate a body in space.) So ones exposure to or non-exposure may reduce the acceptance of professionals, and minimize their earning potential, but the greater loser is society at large when preconceptions, such as the one against classical music or the one you espouse against those with little or no formal training are allowed to restrict the availability of those talents to the world (and the corrollary of poor performance as a comparison standard.)

Lots of SELinux denial messages.
I have upgraded to F11 using the upgrade from the update process. And it went smoothly. However, I am now getting a lot of SElinux messages (I had to set it to permissive to get anything done at all.) I have submitted bugs on two of them, and will submit more bugs later. I have relabled the system (extensive and took time) used the restorecon command where it was recommended, but still there are messages, and I need to get those resolved prior to turning SELinux back on. So I am including a few of the most predominate messages in this message. If you have had these and have a cure, or know some approach that is safe to turning these off so I can re-enable SELinux, please let me know. If I get no responses in a day or so I will submit bugzillas on these as well. I should note that while the first shows a time of around 0300, my system was idle at that time. I went to bed at about 2:30 and rebooted at that time. Also I emptied the que of alerts when I logged on, so these showed up today since about 9:30.

Re: For hardware engineer types re: sound controlers and/or codec chips ??
explanation). So logically the Main processor will set up a process on the system that will send and receive encoded digital streams and tell the audio circuitry what is coming, how it is coded, how large the blocks are and so forth for sound output, whose size and transfer method depend upon the current expected standard and the chipset in use. The audio circuitry will process the digital input to sound output for speakers etc. The corresponding operation for audio in will setup the processor on the audio board for the signals to process, the method to use and size of the data blocks to transfer. The audio input from the microphones or other analog inputs are then sampled into digital data appropriately encoded to pass back to the computer where a waiting process will dispose of the data in the appropriate manner for the application. I hope that helps.

Re: Question on shredding a terebyte drive
Earlier on in one of the threads, someone compared encryption with an envelope. That is pretty good. You know the information is in there, but the only way to get it is to open the envelope. The question is how long does it take to open the envelope. No encryption is unbreakable. The value of encryption is how long does it take to break it. One benchmark that is often quoted is a bruteforce attempt. Although it is not literally a every combination of input attempt, it is quite similar. If a single very high speed computer were used, and the algorithm was known or could be guessed, how long would it take to retrieve the message? This is those long years you see published. The purpose of encryption is simply to make the data harder to retrieve, not conceal it indefinitely. Some algorithms are meant to conceal just until the message is delivered, some to conceal for days, and some for years, none shield for centuries, but attempts are being made daily. Moreover as encryption algorithms become better understood, the applicable means to break encoding become more numerous, and the power of the computer (about 100Billion times more powerful today than in 1967) make encryption less and less secure at all levels. Of course computer speed also lends more encryption methods to the person shielding information as well, but that is basically an efficiency algorithm, not applicable to the direct computation of breaking any particular code. Alternate languages are the best bet. It is impossible to replicate the cultural differences on a computer (at least that is true today I think), so languages have distinct attributes that lend them to expressing ideas in a different cultural idiom, and until the language and/or culture are known, it is unfathomable, unless you find a decoded bit that you understand (the rosetta stone for example). Navajo code talkers were used by the US military for that same reason in the Second World War. If you are a number or math nut, encryption, prime numbers, fibbonacci numbers, and transforms of all varieties will be a really interesting topic of study. Your signature says that you are a professor of political science. Think about the political and cultural evolution of language, and then think of encryption as a means to code the thoughts of one culture to make it unique. What forces act on that to keep it quiet, and what forces work to weaken the culture. That is a form of code breaking.

Re: Testing upload/download bandwidth speeds for verification
It should also be noted that there is latency related to physical transmission speeds, so if the upload or download does checksums and verify handshaking, then there will be a delay of the roundtrip at the speed of light. Now this seems very fast to most folks, but electronically it is measurable, and on lines of several miles in length, it amounts to microseconds per block. If the block size is say 4K, and you download 4M, that is 1000 blocks. If the delay is 1usec, the total delay added is 1ms, or nearly 5000 bytes decrease at 5Mhz. Also there is additional overhead on normal transmissions that may not be in place on the speed test, and the speed test probably relates the bits/sec, which is not the same as the number of usable bytes, since the TCP uses quite a few bytes per block to specify various things about the transfer. All of this slows the response for actual file transfer, in addition to loading of the sending computer. On the speed tests, check both local responders and remote. I am in California, I regularly use Irvine and a system in New York. there is quite a difference. Regards, Les H On Fri, 2009-08-14 at 23:41 +0800, Ed Greshko wrote: Daniel B.

Of the several sites I have tried, they all more or less seemed to be in close agreement with one another in terms of the bandwidth speeds, i.e. my connection speed is quoted at 768KB/s up and 3MB/s down, and the farther away from central, the more reduced is the speeds are. The average speed tools says that I have measured speeds of 720-30 KB/s up and 2.0-5MB/s down. Why is it however, that when downloading software from the various Linux/M$ and other downloads sites I am seeing on average, speeds of 200-320(max) KB/s and never see anything much faster than that? Is this normal? Yes, very normal First, the download speed get from any site can only be as high as their upload speed. Second, run the web based speed checks from 2 or 3 different sites simultaneously and/or the same site multiple times simultaneously and see what the results are then. Those two things should shed some light as to why it is normal. Oh, and third, the software download sites probably also have rate limits on each upload (from their point of view) so that everyone gets the same level of service. All of these reasons are the driving force behind the development of bittorrent... Has anyone gotten download speeds any faster that what I have reported? What I am trying to determine is if my ISP only shows un-throttled speeds between me them, but then somehow throttles my bandwidth usage when I am using the Internet, or is it more probable that download speeds are being throttled from the download site itself? Other than by using `speed testers', I have yet to find a download site that pushes out more than 2-300KB/s?

I am also using Thunderbird with the Enigmail plugin. I too have my system set up for Automatically Decrypt/Verify and was previously forced to have long delays every time I saw a message from him. AND I too have taken pains to have him filtered out of my sight. I am new to the use of PGP but I have studied it from the math, to the computer interface, to the historical and to the sociological aspects. We send mail via post office all the time and we sign them and seal our messages in an envelope. PGP is the same thing. I can send mail and set the From line to Barack Obama and it's trivial to do so. Or, I can send mail out as you and most people wouldn't be able to tell. We all know about how big a problem identity theft is and yet so few of us sign our mail. That absolutely fascinates me. So while G is acting like a nitwit by not even understanding how his behavior is fundamentally rude, I'd like to take this opportunity to encourage more of you to start signing your mail. There are basically two ways to do it. You can either use the PGP(or GnuPG) scheme, or you can use S/MIME. S/MIME is better for scalability in corporations. PGP is better in public. PGP is free and for SMIME to properly work, you have to get a cert from some trusted Cert Authority (CA). For most people, that would mean Verisign, and for others it would mean certs that shouldn't be trusted in the first place. Anyways, I said what I wanted to say and you can all do what you want, but maybe at least a few more will be better informed, and that's really why we're all here. This message is signed, but if you read it, you'll at least be able to fetch my public key. Hi, Steven, The point about the envelope is a good one. It is a point I never considered. But g's attitude doesn't make me fond of signing, in fact it does more to discourage users of messaging services to not use PGP or SMIME to sign messages. His actions slow access, disturb the flow of work and as you pointed out is generally rude to the users of the list. As to someone signing messages to look like him I don't see how that could happen, because the messages would have to be signed using his private key, unless he posted the private key as well. In any event, even your signature shows up as Valid signature, but cannot verify sender on my evolution. I have checked before to see what servers are searched and it appeared correct, but since it cannot verify sender, what does that really tell me? If the email were business related I would be suspicious the first few times, then forget about it as regards your emails, but wouldn't that weaken the process? In short, the problem I see with signatures right now, is the process is not well documented, and has more players than should be necessary. I don't know the solution, but the problems are somewhat self evident. If I cannot decipher some sigs, and cannot verify others, then what value is the process, and why would I add that overhead if it doesn't bring some real benefit. I am not trolling here, just stating the case as I see it. One might make it more robust and not pass on unregistered emails, nor those that do not pass verification (whatever that may end up being). But that would be the end of spammers as they would have to register, and be verified. There are too many interests with cash in hand to make that realistic. Any thoughts?

I haven't checked lately, but I know for example that Fedora had some tutorials started, and that we have discussed this issue before, as I stated earlier, though things change. What was the best is now a bit long in the tooth. Maybe we need somewhere to collect the current best available list of documentation and training. Unfortunately I don't know how to implement that, but I know that it is an issue. With paper books, they had copyright dates, and often the preface told which software version they addressed, and I would often refer to those bits to see if the data was accurate and up to date. But many on line documents seem to leave that out. So how does one go about checking what is the best sources for training and reference material?

A wifi antenna doesn't normally connect via USB, but via a screw-on coaxial connector (a smaller version of what you find on cable TV boxes). Hawking makes a number of different external antennas which seem to work fairly nicely. Make sure you get one compatible with your wifi setup (e.g. 802.11A and 802.11B/G use different frequencies). Also, I believe that some really only work with matching hardware. I added an Edimax antenna to my router, and it actually gave slightly less signal than the router's own antenna. Most of the add-ons are highly directional (mine are, but I want them that way). That may also play a part. I did know that, but no matter what I did, I couldn't get a good result. I think it was a mis-match, somewhere along the line. I have a couple of Edimax PCI cards. Maybe when I have time to play I'll experiment and see if they get a better result. I would like to thank all respondents for your help. Paul Antenna's are more complex than they appear. Think of how a bell sounds. If you change the shape of the bell a bit, its sound changes, and the area over which it can be heard also changes. Antenna's are like that. Moreover a bell has one dominant mode or tone. Antenna's do that too. But WiFi is not antenna friendly. It is comprised of many tones, spread over a wide range, kind of like a piano keyboard. So the antenna needt to match that frequency, and work for all the associated tones. In addition there are requirements for the area over which it can be heard. RF engineers call that the radiation pattern. Some antenna's radiate in a donut pattern. This is the basic type of antenna, called a dipole. BUT the radiation that is above and below the desired places where receivers might be is wasted, so good WiFi antennas are designed to squish the donut, and that squishing causes more radiation in the desired areas and less radiation in undesired areas, which the antenna manufacturers call gain. In other words the signal travels farther in the desired direction. So for a good wifi device antenna, the radiation pattern should be flat (gain of 3-5 db), and the graphic of the radiation should be a sort of wheel laying on its side. To make this work, the antenna needs to match the transmitter for efficient power transfer, and it needs to be mounted away from interfering objects at least 3 wavelengths (about 1yard or 1meter from walls or objects as tall or taller than the antenna). Hope this gives you some background and some idea of how to get the best from your antenna purchase.

Re: Ideal Swap Partition Size
, the local cache memory is also re-done to match the new block, which may or may not generate additional local cache (the cache in the processor memory) misses, requiring more memory be moved from local RAM into the cache ram. To keep the processor working at max efficiency, most MMU's and processor systems can do a bit of look ahead and hopefully get the memory stuff done before it is actually needed. Most systems today implement these memory moves by DMA (direct memory access) which means they occur during the non-memory access cycles of the processor. For example, a jump instruction without look ahead takes about 11 processor cycles (depending on the architecture). One cycle reads the instruction, and one to four more read the address (depends on the exact form of jump and associated actions) and 2 or 3 cycles to decode the instruction, then one to two cycles to change the instruction pointer to the destination. Since the cycles to decode the instruction and the cycles to set the instruction pointer do not require memory access, a DMA process can use those cycles to perform the cache and swap operations, often simultaneously (by managing the addressing appropriately) and without interrupting the flow of the processor making the whole thing virtually seamless. However as the processors have become pipelined, and the memory access more cycle intensive, DMA is not as efficient as it was once. Fortunately the changes in memory architecture have had some effect on that as well (DDR means Double cycle, and because it is double cycle) the read lines are different from the write lines, so some simultaneous read and write operations are possible if the MMU and board addressing and so forth are designed to support it. This also requires some fancy footwork on the RAM boards, and/or the ram chips themselves. I hope this is fairly clear and mostly correct. Please feel free to adjust my input if not. The only thing constant in high tech is the rate of change.

I would have great reservations about this due to unexpected interactions of things such as backups, access to certain system files (through /usr/bin and /usr/sbin) for example, especially with multiple users on the system. By convention, many applications expect /home to contain user directories, and while if coding standards are followed, the shell variable $HOME will point to the correct directory, in some cases poorly written or experimental code is sometimes not so clean.

Re: Advice to an audiophobe ??
sound, rather than the CD like quality of using 16 (or more) bits per sample. The catch with all that is it takes up a lot space. To solve space issues (less a problem now that storage space costs a lot less), compression schemes were developed. Most take advantage of reducing the number of channels eg to mono, reducing the sampling rate, or the number quantizing levels (bits/sample); but this is done in context of the type of audio being compressed - eg human voices are typically of lower frequency, and can sampled at a slower rate, and with less levels. The biggest jump in compression was with psychoacoustic modelling, where it was found that in a complex sound, a listener does not notice that certain frequency (pitch) sounds become inaudible (or masked) by other sounds. The reason there is so many formats, is because developers were essentially competing to produce more highly compressed audio files, without noticeable change in quality, when using a certain type of audio, over a certain communication medium. Eg: when the fastest home internet connections were slow modems, compression made it possible to transmit voice signals over your internet connection. If you tried to transmit music of higher quality that voice, you would have large audio distortions that made it difficult to hear the original material. You might like to play with the audio editor program audacity (perhaps from rpmfusion if you want to be able to import and save in certain compressed formats (mp3)). It shows you a graphical representation of the audio file, and eg lets you choose a zoom, start and stop position, and just play back small parts of a file, so that you can work out what the sound looks like to a computer. Hope that helps a bit more ;-) DaveT. Hi, Dave, I work in the IC Test industry, and that is the clearest non-math explanation I have ever read.

I see that the Instinct has GPS; I generally know where I'm going, but I'm amazed that when driving during evenings on the New York State Thruway at how many people have a GPS device of some sort visible through the window. Perhaps I too would find GPS useful. The instinct has a handy 'search' feature to locate nearby restaurants, banks, and about anything else (gas by price, etc.) that is handy when traveling even if you know the route. It also has 'movies near me' where you can drill down to review, but that may be on all the sprint phones with gps and data. -- Les Mikesell lesmikes...@gmail.com -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

Excepted a good technical writer **paid** enough to spend on the subject lots of time, since it isn't an easy task by any means. Actually Marco, I have written many documents, and am a pretty decent technical writer within the area of my particular expertise. I am a Test Applications person who wrote over 60 programs for Teradyne Inc. along with several hundred pages of documentation on system use and technical skills for test applications. You would find some of them in nearly every company in the world using Teradyne systems. I wrote and delivered training on RF, Video, DSP, system correlation, and several other topics, and no one ever complained that they didn't get their money's worth. Yet even my documentation was often improved upon by those who followed later. That is engineering in progress. Some of those changes were patently wrong as well, and often what the uninitiated see as a failure of the documentation is really a failure in following well what was written. In many cases the folks who criticize documentation haven't actually read it. I read nearly a 1000 pages a week of technical documentation, and that is what makes me good at what I do. The field for Technical topics is not ever static. During my career, from vacuum tubes to DTL, then TTL, then MOS, then CMOS and advanced BI-CMOS, some DMOS, and of course the advanced processes today where devices are so small that you practically need a microscope to read their labeling, the field has continually advanced. Advanced architectures today for software, hardware, and OS's are changing at an increasing rate, and have been for decades. It won't stop, or get easier, but only magnitudes of more difficult if you do not keep up. When you talk about how docs are broken, and then refer to Wikipedia, you are not looking at true technical documentation, but historical documentation, and there is a real difference. What is needed for technical documentation is indepth knowledge of not only how a system works, but why, and why you should not short cut the means and methods supplied. Does that mean that everyone will read the documentation? Of course not, and of those who really read the documentation, how many will actually act according to the document? My experience is that at every engineering site, there are one or two guru's, and they are the ones who actually do the grunt work to understand how things work. They read the documents. Most of the rest to some degree piggy back on those few. That's not bad either. It is human nature. The best companies find out the best capabilities of each and capitalize on them, as well as working with their weaknesses to improve the people within the company. The most successful companies leverage that expertise across their customer base and across product lines. And that leveraging is accomplished through abbreviated documentation targeting specific needs, along

The truth is that writing should be part and parcel of every engineers job. However it is seen as grunt work by many young engineers who have not been well exposed to the need for documentation within their education. Programmers are taught self documenting code... What an oxymoron. We do call it code for a reason. Hardware and software engineers are not well educated in the need for documentation, and seldom given any time at all to do that portion of the job. If you take time to do the correct support task some fool that doesn't know anything about the task, the skills, the knowledge, or the overall expertise of state of the art will criticize it. As a result you get bad support, poor products, and the inability to transfer knowledge. Read the documents on ANY software package built on object oriented code, and tell me how many bits of the data, code and operation are required to actually accomplish the given task, or how it can be improved. Ever tried to optimize object oriented code? I have. There are a lot of educators on this list. I hope they read my last post on this and this one.

What we're discussing now, that is your just do it, someone will fix it approach, has nothing whatever to do with the software license. Because we're talking of documentation written, or possibly improved, by third parties, not the developers. What happens to the people trying to use it relates very much to the license, although only as a side effect. Commercial software vendors tend to maintain their own knowledge bases and attrition takes care of cleaning up the things that are out of date. With free stuff, you can probably still find copies of anything that has ever been released and it will clutter any searches you attempt. I don't have a solution for this - it is just an observation that if anyone ever releases bad documentation or even advice, others will be finding and following it years later via google and other archives. but this is a problem only because releasing crap documentation (the just do it, someone will fix it kind) is much, much easier than releasing good stuff, which is again the only point I was making. In the Postfix example, if such documentation existed the Postfix gurus would simply tell newbie don't read A, read B. Instead they say don't read A, read the mountain of over-detailed stuff at postfix.org even if you could go by with one decent, ten page how-to. One decent ten page how-to is right for 10% of the installs, a different ten page how-to would be right for a different 10%. But there's no way to find the one you need and avoid the others. I have a different take on this. Complex programs like postfix have (and need) thousands of options to cover every possible case... Rather than confuse people who should be just following standards with the thousands of options they shouldn't touch anyway, we need a dozen templates for this sort of program. Right. Now, who could write such good templates, ie distill without errors those thousands of options and explain the result clearly, in order to minimize misunderstandings, except the developers themselves or (much better) some pretty good technical writer who's either paid to do it or already financially secure? None of the above. Only a person who actually runs the program in production over a period of time will have a usable template, and it will only be suitable for some subset of other situations. The problem is that he has no way to share his work with the thousands of other people who could use exactly the same setup, and those thousands of people have no way to find the dozens of good examples that exist whose owners might want to share them. For the code, there are source code archives where you can easily track changes over time and alternate branches of development - for a very small developer base. For the much larger user base there is only a choice of 500-page books detailing every obscure config option or the single default config that comes with a distribution. We keep going back to the original point, don't we? (and probably could well stop here, since we're not the ones who could fix this and it isn't Fedora-specific in any way) Who could fix it? What we need is a location and mechanism for admins to share their config files with similar tools that code developers have to maintain versions/branches etc., and view diffs across them. And to whatever extent possible, fedora could produce alternative packaged configs on the order of the caching dns server that would help some subset of users. Making an end user need to know about a million config options to create one of a dozen or so common setups doesn't make much more sense than just throwing the source code at them. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

For the latter, people should only need to know what it takes to make them work. If you can ship something that works the way the user wants it to work, they don't need documentation any more than they need the source code (...the real documentation at that level). If you don't understand how these are intertwined, consider how almost any variable could be left in the source or extrapolated into a config file - and in the case of interpreted programs like perl or shell scripts the configuration may in fact be a piece of the software itself, sourced at runtime. The 'one-size-fits-all' concept of the distribution RPMs doesn't quite work to provide configurations that 'just work' for everyone, but a few dozen canned configs might cover most of the cases. This is, of course, a different issue than 'how do I connect a form in openoffice to a table in postgresql?'. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

M. Fioretti wrote: Right. Now, who could write such good templates, ie distill without errors those thousands of options and explain the result clearly, in order to minimize misunderstandings, except the developers themselves or (much better) some pretty good technical writer who's either paid to do it or already financially secure? None of the above. Only a person who actually runs the program in production over a period of time will have a usable template This is exactly what a responsible, professional tech writer does before writing. Either he runs the sw himself or nags to death the developers and testers to figure out what their notes and internal docs mean. Tech writers and developers often can't test in production scales themselves - and developers are way to optimistic about things. I'd expect someone who actually keeps a large university mail system running to have a much more realistic config file than someone who only looks at the theory. The problem is that he [who has a usable template] has no way to share his work with the thousands of other people who could use exactly the same setup This is false. All that person should do is publish online one page with that template and a few clearly written explanations of its content. That's equally true for source code, but we don't expect users to build their systems from scratch by gathering up source code page by page from random users they don't know in random, distributed places, do we? It's writing the clear explanation which is hard, which is a good part of why those templates don't pop up every day. Explanations are mostly irrelevant if you it works like an appliance. If you need details you can go to the source. Who could fix it? What we need is a location and mechanism for admins to share their config files with similar tools that code developers have to maintain versions/branches etc., and view diffs across them. Les, I have made one general comment about how difficult it is to write good documentation on whatever subject, never mind Fedora. Now you are talking of something which has nothing to do with the topic I suggested. The fact that I used a Postfix example doesn't mean that the good docs problem is only for initial configuration, I thought that was clear, sorry. Postfix is a perfect example. Very few people should ever need to know any config options for mail systems. They just need one installed that works in one of some small number of siturations. Having a config files repository would be absolutely useless for a newbie user of, say OpenOffice or Kde. Agreed - there is a big difference in end user run-time operation and administrivia. But they aren't treated differently in the distributions, which contributes to the reputation of open source documentation that started this topic. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

The resulting files should be somehow compressed and easy to access when needed. (I go on the presumption that you only need your backup if you don't make it.)

Re: Network Card Naming Issue
Bill Davidsen wrote: Actually, no. The method is to use UUID and totally ignore hardware names. That's what current /etc/fstab and /etc/mdadm.conf do these days. Right now, the key hardware components are remembered by udev. As this new method matures, it will become easier to maintain/remove hardware. But think of the alternative! The old way might be ok for single drive, single interface systems, but not otherwise. There are many of us who remember the 'bad old days' when this issue was capable of destroying months of work! The hal stuff was written by people who were wedded to matching the same device to the same name. Putting MAC address, UUID, or serial number in as the key is far more reliable, and allows people to to have a single place to specify the match. Having to beat up sysconfig and hal to change a failed device is not conducive to good system administration. Your points are well taken, but I consider hal keeping it's own ideas instead of using sysconfig to be a bug, not a feature. You do need to be able to move parts around as well as replace old parts in an existing system. And you need to be able to do image copies of drives. What happens if you put disks with duplicate labels (for years they wouldn't boot...) or uuids into the same machine? What if you put disks that previously used to be the same-numbered md? device from 2 different machines into the same box? It has been a while since I tried that, but it wasn't pretty.

The md device number seems not to be an issue. If I put it 2 sets of drives that used to be md2 in former machines, which set will become md2 and what happens to the other one? Using a non-unique UUID on a system is the same level as swapping two hard drives and using the physical device name to determine how they're used, if you make an effort to shoot yourself in the foot you will wind up with a hole in your shoe. Deliberately creating a condition where the information used to tell hardware apart is ambiguous is dubious practice at best. Making a unix-like system that can't deal with dd-copied disks is shooting everyone in both feet. What if you want to replace your current eth0 with a different card and shift the use of the existing one to a different subnet? Have the info in one place, sysconfig, not sysconfig and hal keeping their own idea of reality. Being able to set this in one place is good, assuming that two places will always match is unrealistic. People screw up, restores happen, one place is right or wrong, but never maybe. And all of this gets in the way when you need to restore your backups onto a similar but different box. If you make physical backups of drives that is the least of the problems. The disk part will work as long as the replacement motherboard has the same controller type - and you don't put 2 copies of the same disk in it at once. But your network won't come up, so it's no fun when you have someone replacing stuff remotely and you expect it access it again. The UUID isn't backed up using by-file backup, so conventional backups by tape or rsync aren't a problem. You always have a problem, you are just moving it around. Now you have a machine that won't boot, and if it did boot, would have fstab entries pointing at uuids or labels that don't exist. Finding that two drive made a few months apart, with the same part number, are actually slightly in size is painful reality, the only things I backup with a physical backup are VM images, and usually not those either. The problem of mismatched identifiers is always going to exist, depending on which part you swap, and the motherboard, nics, conrollers, and disks are all equally candidates.

I can ping the host machine, it gets an ip, it gets DNS, and all, but cannot surf :( Anywhere you send packets needs some way to get the response back to the sender. One way to do this is to plan things so all of your private subnets are unique and add routes toward the gateway interfaces for everything else. Another way is to NAT the source address as it goes out the already-known interface. That way the rest of the world does not need to know about your new private subnet. As a packet goes out, the source address of the client will be replaced with the address of the forwarding interface and the host performing this will maintain a table of connections to do the reverse mapping as the reply packets come back. If you tcpdump your eth0 interface now, you'll probably see packets being forwarded out but nothing coming back because the rest of the net/world doesn't know the route back. When you add the SNAT, it will look like the host machine itself to the rest of the world. The argument to -s is the range of original addresses to replace, -o is the outbound interface, and --to-source is the IP of the outbound interface on the host. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
