It is to the user a filter that requires a key. We tend to make it more difficult than it needs to be, where the truly difficult portion is understanding security. There are possible alternatives for that as well, but generally keys should only ever be handled by the folks dealing directly with the encrypted data, and the key used should be only known by those folks as well. That is the difficult part. But part of what makes the whole process obscure is the fact that everyone has differing views of what the proper handling of keys, and how and where to decrypt the data, and how to protect the machines doing the decryption. Moreover, it is the distribution of false beliefs that make otherwise secure systems insecure. Add to the issue is the problem of government monitoring of traffic, with the attendant need for them to be able to decrypt possible questionable transmissions. There are schemes that make encryption virtually unbreakable, but proving that is a bit difficult. There are also techniques that obscure the "real" data from bogus data, and systems that obscure senders and receivers, but these are indeed complex and probably beyond the scope of the simple encryption of email. Simply put, one could create a keylist, publish it someplace secure with limited access and limited time availability, communicate to the designated individual where and when, and the designated individual could use something like VPN to pick up the encrypted key list. The key to break that key list could be given over the phone. The result would certainly minimize exposure of the keys. Once the keys were installed in the designated machine, inline synchronous decryption of the keys and the communications could be virtually invisible to the user. The remaining issue would be machine security and how to handle output and input for security purposes. But those are somewhat separate questions of three types, one is physical security, one is emission security, and one is document handling. Each would need processes in place and understood by all users. The truly hard part of any secure system is the user understanding of how security applies to the actual information and the keys. And that is the most difficult part of all, but I wouldn't call it confusing, just really detail oriented.

Opengl and F8/F9
Hi, everyone, It appears that Mesa is supposed to replace OpenGL for F8 and I assume for F9 (haven't upgraded yet), but the croquet application doesn't work, due to an undefined module. I looked for an implementation of OpenGl for F8 and couldn't find it. Does anyone have a hint, a known repository or ??? that might supply the required library?

Often unnecessarily. Jump tables were generally utilized to speed up decoding a passed register, so that instead of a series of decrement and jumps, the base of the table could be loaded, the argument doubled and added (16 bit addresses), and a mov PC,(hl) would accomplish the task. It seems to me that this was about 35 cycles total, which make it faster for calls with more than 3 frequently called routines. What one person calls messy is good coding to another. Jump tables were used in almost all assembly code that I remember seeing where any good amount of optimization was required, and that was pretty much processor independent. I liked the Z80, although some of the non Zilog implementations would frequently disturb the top of the stack often. I have also hated reading the assembly code for any processor where people kept old and useless code in the program. If it no longer did the job, why keep it in a running executable. If you wished to keep it for historical purposes, archive the butchered copy, clean up the release code, and add a comment why it was changed and the name of the butchered file for reference. Add documentation to the butchered file detailing why it was changed and what drove the changes, so that the future engineer who might be tempted to look would have good information. But from my experience, who ever has time to look at butchered code, or as in your case now, clean the mess up? It is tough enough to get clean code working and delivered. JMHO.

Re: Google Earth and nVidia [partly solved...]
Just a guess here, but check where google earth is installed and in the temp directory to see if any files were created as root. Temp or rc or init files being set to root will often keep user applications from starting in linux and unix systems (one more reason using root to run applications is not a good idea.)

Re: tr problem
Actually early print programs just dumped files to the line printer (a teletype or actual row printer). Thus the file had to contain the whole information. At the time, no one could forsee the situation we have today of displays which do vector, rastor, bit mapped, and so on. Moreover, as time goes on, we will find issues with todays file formats in dealing with 3d or immersive displays, or even displays in some as yet undefined multidimentional/multisensory format. No one can forsee the future. And while I dislike the issues with text presentation that occur, I do understand the history of it, and the issue of backward compatibility. You might find it entertaining to look up some of the history of text editors some time, and certainly informative. But as to the format vs the display, they are never fully independent, although software vendors and standards organizations do make heroic efforts. And by the way, these issues are not restricted to text. You might be interested in the issues confronting the virtual reality folks now, as VR seems to be the next WEB killer ap. The avatars, the avatar properties, avatar characteristics, avatar wardrobes and actions all are facing similar issues, where it is impossible for some one to establish an on line personna that will move freely between VR environments. This is similar to the text issue, because for it to be solved the definition of what is needed for correct file representation and what is needed by each application must be resolved before a comprehensive design will be able to be standardized to move between worlds. Perhaps with your great insight you might provide the Second Life, VRML, Croquet, Cobalt, WOW, and others with valuable information on standardization?

Re: nvidiafb problems
Hi, Russel, Segfaults are probably your best indication of the problem. Generically a segmentation fault occurs when you access memory allocated to another process. You can tramp all over your own processes memory and not necessarily generate a segfault. Since you are seeing the problem when the size of the field changes, probably there is a fixed array somewhere in your code that is inappropriately sized for the larger screen sizes. Also, if the Video processor is only sensing 64M, it may be doing something weird as well. To trouble shoot this problem I would probably first check the video processor to make sure it is properly seated in its socket. Next I would go carefully through the code looking for hard sized arrays or fixed malloc sizes. Check the #defines carefully to see what they have and what comments you may have added about display sizes. Then look at any pointer use to make sure that it is cordoned off from exceeding the array sizes in use. After that you will need some software to monitor memory. Several forms exist, and I haven't used any in years, so I cannot recommend one for you. But if you check the archives, you will find some references last year if I remember correctly. Also because Nvidia is proprietary, the group here has no vision into their code or processes. And if your code is producing segfaults, that needs to be cleaned up before submitting bug reports anyway.

The quality of the heuristics continually improve, and are much better than that. Typically heuristics are applied to programs and program errors that remain after other methods have considerably narrowed the list. I suspect that their accuracy greatly exceeds 95% these days due to the order of application, and that is improved even more by some background software applied after the heuristic ID. Please don't overstate the case. It is hard enough to get people to run antivirus now.

Typically that is what causes the error. A well designed interface uses the supply wire to controll the voltage on the interface logic. If you are getting scrambled data, one or the other of the ports is probably not supplying the voltage for the interface. Or alternatively the ground may be broken at either end or in the cable. Losing the voltage will make one interface not pass valid data, losing the ground loses the reference to the receiver comparators, which will make them decode junk depending upon the transitions on the cable.

Re: F8 and a GPS -OT (HTML for drawing)
Gene and others will correct whatever I get wrong... The original specification was for a serial interface to multiple devices. If you look at the entries below 0x20 on the ASCII table, you can gather such gems as DC1 and SEND and some others. These were meant to control multiple devices on a single serial port. This is part of the software specification. The hardware specification implemented two serial busses in a single connector. Although most hardware never implemented the second bus, instead treating the one as bidirectional, which reduced the effectiveness of RS232. Also most software folks outside of IBM and UNIVAC seldom implemented the full control spectrum. The line drivers were supposed to be cabable of 20ma loop current. This meant that the serial loop could pass through a chain of devices, each of which could receive and transmit data. You could select which device(s) were active by chosing device control codes which would act on specific hardware in the receiving device. Its primary use was for communications, driving data to modems and receiving data from modems. Generally most folks would ground the shield, which was sort of an error. What should happen is that the shield is the return path for the transmitted signal. from the DTE. Signal ground is the return path for the signal originating at the DCE. Thus properly implemented the two sides have different ground references. At the DCE (modem or printer for example) the signal ground carries the return path for the signals going to the DTE. the shield carries the signal return to the DCE. Thid implied that who ever was working on the line had to remember which line he was on. 200' of line in a high RF environment or high loss environment could build up quite a charge if it were not dealt with properly. Inside the equipment, the receiving block at the DCE would tie its input circuits between shield and a floating 5v signal. It was never really floating, as there would be a high value resistor between the shield and signal ground. The transmitting block of the DCE would be tied between DCE +5 and signal ground. At the DTE end its transmitting block would be tied to +5 and shield to ground, with signal ground connected by a high value resistor. Its receiving block would be between a floating 5V and signal ground. NOW all that is the theory. In practice shield ended up being connected to case grounds on both ends, and signal ground was used as the reference. This meant that you had some signal degradation on simultaneous transmit and receive, resulting in the buss being used alternately for send and receive. Also most manufacturers didn't want floating supplies, so that ended. Finally they balked at the additional $3.00 or so for the line driver bits, and used normal 7400 or DTL logic for the lines. the result was lower speeds, shorter distances, loss of noise immunity, and too many unused pins on the connector. In came the DB9, and a host of other hardware interfaces, out went the lines available for ringing (the anonymous test lines), and so went the story of slow, limited line length RS232. So basically all you need is the pinout in the bottom connector of the drawing (DB-9) or one of the other interfaces, short leads (generally <6') and you should be all set. There isn't much that can go wrong other than you may need a null modem connector to transpose the two serial wires. They are available all over the place, or you can simply open up the offending connector and swap them there.

Re: E-mail
Check you email account. You are looking for the following: Open your email. For Evolution do the following: edit->preferences This will bring up the preferences window and will highlight the current account, or the top one of the list. Select the mail account you want to fix. Choose Edit from the right side. Check that the email address is correct. Then go to the second tab, Receiving email. check the server, and the username to make sure they are correct. For Yahoo, choose Use Secure Connection SSL encryption Under Authentication type choose password. For receiving options chose whatever you want Under Sending Email, choose SMTP add the server they told you. check Server requires authentication choose SSL encryption Authentication PLAIN, unless they have told you otherwise Username is typically your email address and is probably OK. Defaults and Security you set according to your preferences. This should get you past the problem. SSL encryption is the deal that they are bugging you about. The server name is critical. Some of their servers are used for some other things, but will do some email as non SSL, but they flag it and send you an error message. There is somewhere you set up the service addresses, but I have managed to forget that part. Perhaps someone might google it and finish the setup for you.

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 o

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. Our societies depend upon the software and hardware being designed and built today. Your cars systems, aircraft systems, medical systems, alarm systems, communications systems are all becoming vulnerable to loss of knowledge and expertise. Sorry Marco, just one of my pet peeves.

Becuase it is not just a "sandbox", but a permissions thing. Processes a user can start don't have write access to the global system. Processes started from a root account do.

None of these seem to be preventing me from using the system (haven't
tried printing yet).
I'll check the archives to see if anyone has solutions to these, but I
thought that they should go into the record.
Prior to the upgrade I was running F8. I just downloaded F10, made a
disk (two actually, the first didn't burn correctly), and then ran the
upgrade process. My emails were imported correctly and now I am just
starting the update process.
No worries on these, but since this is the place for advice, can anyone
offer any?
OOPS, SELinux is preventing me from opening my Windows disk in Linux.
But while it tells me it is preventing the access, no alert is being
generated. No information on how to fix it.
Ditto for the FAT32 formatted backup disk. This has disaster potential.
I'll try the trick of "touch ./relable"
I.

As such its permissions are a bit touchy, and putting user files there can produce unintended consequences. 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.

I know that a 32 bit system is constrained in addressing to something like 4G, due to the intel addressing architecture, and 32 bit constraint, so applications were developed to go beyond that. But given that the system maps the logical memory to physical memory, and some can do this via hardware, how does adding more memory add more stress? If the system is running the application now, the basic change is reducing swapping to disk, is it not?

the "virtual address" doesn't exist in the machine except as a block reference number that is mapped to a specific disk sector (which is why swap space is not set up like a regular disk partition) and can be referenced more or less like standard memory. Further, when the page miss happens, 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.

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.

Such code these days is generally not implemented due to the MANY serious issues with security, and most languages don't have any implementation for it (other than some runtime object language approximations using overloading to approximate it), and some list processing languages like Clisp. Anyway for the uninitiated, here is a fair explanation of how it works: http://www.cs.sfu.ca/~cameron/Teaching/383/PassByName.html I was going to write a C example, but I am just too rusty in Algol to be sure I coded it correctly. However, the Thunk method as shown using PASCAL is one method of implementing pass by value.

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.

Not quite like having a button that shows it, but perhaps you could write a macro to implement that capability? I have viewed 10 columns with over 3 samples each with this tool.

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.

mon mode" so that the audio system is balanced against ground, and differential. When the ground noise goes into such an amplifier, it is canceled by its own image of the wrong polarity. (this is a simplified 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.

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. There were four more of these
all targeting different objects.

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.) Just my humble opinion.

DVD burning issue
Hi, everyone, I am having difficulty burning an ISO to try F11 on another computer. I want to burn the live iso image to a dvd. I have tried this several times and get a really stupid error. It appears the whole disk is created, and the finished message appears, BUT then the software attempts to create the checksum and things go badly. I have tried this both as my user and superuser, with the same issues. It appears that the cd/dvd library opens the disk, burns the image, then attempts to reopen it exclusively as the raw device for the checksum creation without dismounting it so the remount is denied. But maybe I am wrong. Is anyone else having this kind of problem? And how can this happen as superuser? Are there any known work-arounds? I couldn't find a recent version of this problem when I looked yesterday.

Re: Music Appreciation teaching program ??
real knowledge lies. 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.

I didn't see that in the name... Therefore I didn't know it was an issue. Meanwhile I downloaded another image and finally found a bugzilla which said the problem was related to checksum generation for the image. I turned off the checksum and was successful in writting the DVD image, but the system I wanted to check would not boot from its DVD, due to a bios restriction. I then came back to my system and attempted to burn a cdrom, with no success. Then I added K3b to my system and used it to burn the cdrom, and succeeded. It appears that brasero has some fundamental problems, and the error #12 was returned in all cases of trying to burn the image, and the image would not work. However by turning off the checksum plugin of brasero, I was able to get a dvd and by loading and running k3b I was able to get a CD, so I now have both, and a lot of "junk" disks which brasero never finalized, which I have tossed out. I'm a dim bulb when it comes to these cd and dvd formats, so I will look up the differences. But I do realize that the raw form of the iso image must include the disk structure, so it would be unlikely to work.

The software should run with stuff that is already working to be a good product. Otherwise we will just continue to be an "also ran" operating system. I use Linux on three systems now, and one of them works well, the other two less so, one couldn't update to F10 because of the APIC (sp?) option not working (an older IBM system). Another won't work with my wife's cell phone media, refusing to download her mp3 files (it just stalls, no error messages or any indication of what is happening). The third is still running Fedora 8 because it is just an old box I use for physical trouble shooting on electronics. Overall, I like Fedora, but seriously printer and peripheral incompatibility will kill wider adoption. It is about use, not ideology. If we could wield enough influence then product manufacturers would support Linux. But only if the interface is consistent in the various releases. The ball is in our court, whether we like it or not. And, by the way, why not enable a simple way to interface to Windows drivers? (I'm joking here, I know the issues.) I suspect that Windows has severe limitations on re-entrance, and most likely hasn't publicly documented that process, which is one of the real issues with drivers anyway.

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?

It may be that the website is checking your system to see if it is windows. Ubunto has some capabilities to overcome this dumb check, but Fedora doesn't. You have to add a package to your browser. Currently I use greasemonkey and default user agent. Between the two of them I get access to most sites. What is needed is an ethics rule preventing web programs from checking which system is installed. It shouldn't matter, if the web browsers are standards compliant and the programs are too.

No problem. But I also made the backup just in case. However I never needed it. However on my wife's system I never got f10 to work.

I have purchased several from Microcenter (http://microcenter.com). They usually run from $150 US to just under $1000 U.S. And of course there is the possibility of finding some company that is going under and seeing what they might have for sale. There are also some distributors of older SUN computers that are reasonably priced. Just look around.

error message from YUM
Hi, everyone,
I am running F10. I attempted to review some yum groups using the
Add/Remove Software button, and the window gives me the following error:
Error Type:

If I am reading this debug message correctly, it appears that a lock
file is in place. But the path is not given.
If I use a terminal and do yum commands directly (I tried several, but
didn't keep a log) they seem to work correctly. So this appears to be
some lock that is generated by the Add/Remove Software utility, and not
yum itself.
Any clues? Looking up the yum help on line didn't provide any
illumination (as I expected, since this appears to be the window, and
not the utility).

Les H

But I don't remember them having I.C.'s. Must have been after the 60's. The ones I worked on then had accumulators made up of rotary solenoids, and stepper switches (not motorized, just a solenoid pulling on a ratchet or ratchets to advance the counters.). The randomizer for the match number play was simply another ratchet mechanism that would run for a set period of time, but the steps were intermittant, yeilding a sort of psuedo random generator. There were some that had sequential relays to control some of the kickers, and advance the score mechanisms. They were really interesting electromechanical bits of work.

There are a LOT of bits of information on the web. However, not all are well written or well supportive to the newbie. Some are even very out of date, which in some cases means wrong about how things work now. When a newbie asks this question they are looking for guidance on the best available material. I know that this is a somewhat loaded question, but there are several places that we all use. 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?

Most spam filters will reject email with multiple X's in the account name because that is often spam or an attempt to hide the identity of the sender.

I would add that the brain is marvelous at relating information. If you read enough, even with little understanding, the common information will begin to become coherent and you will learn. That said, if you start with a few beginner articles, and please do the exercises they have, you will learn. The exercises are important to lock the information with the potential errors that you will encounter, and the effort needed to correct them. Like G, I started a long time ago, from vacuum tubes, and while the circuits have changed, the elements of design and software have not. Almost everything I ever learned has benefited me. Go for it!

Re: man 3 switch
b++); but that is probably predictable, but would mean that the pointers would have to be set artificially prior to the call to point one location earlier, and the exit condition would be pointing after the last character. Some other interesting artifacts I have come across deals with macro substitution between debug code and release code, where macros may be substituted for ease of tracing during the debug phase, but the code in the macro is subtly different from the code in the routine used for tracing execution. Works at Debug but not release, or visa versa depending on the conditions of the two implementations. In short, I agree with Rick that you need a book, not just on C, but on the version you have. Floats are another source of errors, due to some using hexadecimal notation, and others using binary and still others some form of excess twos notation. Between them round off 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?

I have not yet been successful in discovering where that package is currently located on my system. I tried a "find . gp*.so -print" from the root directory, but had no success. So my questions: 1. how should I proceed 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.

Any pointers on how I get started would be great. I am more then happy to make my desktop my mail server, since the FreeBSD server is getting a bit old and I'd like to upgrade it anyway so it's not a problem for me to just move the mail service to my desktop if that makes things easier. I don't care so much if my existing email folders are not accessible by my laptop I just want to start making new messages available to both from here forward. Any pointers to how I get imap setup so I can access my folders from two, or more, different machines ? If you want to replace the FreeBSD box with a 'server appliance' that will work as an internet gateway, web/ftp/samba/email server (and probably a few other things but not desktop apps), look at SME server from http://www.contribs.org. It will come up with a working pop/imap and webmail server that you can use from your laptop or other client boxes. You can set up the same programs on other distros, but none are as easy to install or maintain. As for your existing mail, if you can download via POP to a mail client program that understands both POP and IMAP, you will subsequently be able to drag anything you want to keep back into IMAP folders on the new server. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
Re: OT: Does a proxy IMAP server exist?
Tom Horsley wrote: Just curious if such a thing as a "proxy IMAP" server exists? (Preferably already available in some rpm I can install on fedora :-). What is that, you ask? I'd like to continue to keep my mail on the IMAP server at work, but I'd like better spam filtering than the server-side rules provide. What I'd really like to have is something on my desktop that acts like an IMAP server, but really forwards requests to the main server, however it does allow me to do procmail/spamassassin/bogofilter processing of the mail on the corporate IMAP server so I can delete obvious spam, etc. before anything talking to my local IMAP server even sees it. I'm not sure if a typical proxy would give you any hooks for actions on the content. Many IMAP clients can apply client-side rules to sort and filter if you want to keep the storage on the original server - or you don't mind making another copy you could use fetchmail to grab it (with or without deleting from the original server) so you can feed it to procmail before it is stored where you look at it. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

It seems to be more difficult than I thought to send email from one machine on a LAN to another. Is there some line I could add to sendmail.mc which would enable this? On my network, I also need to set SMART_HOST in sendmail.mc to the mail relay host provided by my ISP. Well, I do that anyway. But that means all my email is sent to my ISP to deliver. I want local email to be sent directly. I thought mailer(LOCAL) in sendmail.mc did this, but it doesn't appear to on my system. in this case, local means local (on the same computer) as I said, if you want to deliver mail on your local network...you're gonna have to set up DNS and a system to act as MX for your local network. Sendmail should fall back to A records if no MX exists, and it should accept any names you've added to /etc/mail/local-host-names (requires a sendmail restart) as local regardless of what DNS says. If you want network-local mail delivered to some other machine you can define MAIL_HUB in sendmail.mc with approximately the same syntax as SMART_HOST (i.e. use []'s around literal IPs or hostnames where you want to skip the MX lookup). Then mail determined to be local will go to the MAIL_HUB and you can still send outside mail to a different SMART_HOST. Also on that system, you will need to make it a POP3/IMAP server so you can retrieve mail. Or run mail/mutt, or something that knows how to read the inbox directly. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

As I said, it used to be simple to forward logwatch to a local machine. (I'm thinking 2 or 3 years ago, possibly pre-Fedora, on Redhat systems.) I'm not sure what has changed. The one other thing you'll need to do if you haven't already, is configure the receiving machine so it will accept network mail. Fedora and current RH versions ship with sendmail configured to only listen on the localhost loopback which is pretty useless for a nework mailer. In sendmail.mc on alfred, remove the 127.0.0.1 from DAEMON_OPTIONS entry so it looks like: DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl and make sure port 25 isn't firewalled. Also make sure that alfred has all the host/domain names you might use as target addresses in its local-host-names file. There are other ways to explicitly force mail to go to a certain machine (local DNS with explicit addresses, forwarding files with explicit addresses, mailertable entries mapping to IP addresses, etc., but MAIL_HUB is intended for use where you have more than one internal machine and you want all local mail to go to one of them. If you also do internet mail you can configure this one to relay and be the SMART_HOST for the others, perhaps with address masquerading but they are separate concepts. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

I'll pursue the missing message - I should be able to work out where it has gone. Maybe sendmail is modelled on the Irish postal service ... Probably the receiving sendmail needs to be configured to allow relaying from your source host. It's not relaying to accept for local delivery. The receiving side needs to be configured to accept over the network (remove the 127.0.0.1 restriction from DAEMON_OPTIONS), test by a telnet to port 25 from elsewhere, and it needs to know what to accept (add the name to local-host-names if it can't look itself up in DNS and get that name).

So how do you use tr?" Why option -c? tr '\r' '\n' filename2 would do it. Cuz the manpage says that it triggers the character convert thing? No, tr actually takes 2 'sets' of characters even though in your use you only need one character in each set. For example tr '[A-Z]' '[a-z]' would lowercase a file (and the brackets and quotes aren't strictly necessary but would be on a sysV version). The -c option means to complement the first set (i.e. it becomes the characters not included). It doesn't touch on its performance if the option isn't given. And it doesn't mention using the quotes either, but it worked just fine, thank you very much. Man pages generally never mention the things the shell does to a command line before starting the program. This will include expanding variables and wildcard filenames, redirecting I/O, and other things triggered by shell metacharacters. In this case tr doesn't particularly need the quotes, but if you don't use them the shell will parse and remove the \ characters (treating them as quotes for the following character in its own parsing). These details are the same for every command you type (or script) and not repeated in every man page. -- Les Mikesell [EMAIL PROTECTED] -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
