 2004/10/19-20 [Computer/SW/Languages] UID:34229 Activity:nil 10/19 I know leap years occur every 4 years, but there was some exception to that. Can anyone tell me what it was? I believe it involved years that were multiples of either 100 or 400. Thanks. \_ http://www.boulder.nist.gov/timefreq/general/leaps.htm \_ Year mod 4 == 0, leap year Year mod 100 == 0, no leap year Year mod 400 == 0, leap year ... possibly some other wrinkles. It basically come from the decimal expansion of the number of days in a year. Of course the length of a day changes too... \_ More specifically if ((year%4 == 0 && year%100 !=0) || year%400 ==0) leapyear = TRUE; else leapyear = FALSE; \_ Ergh, don't write if (bool) x = true; else x = false; statements! Just set x = bool! \_ The above is right, and there are no other wrinkles. Incidentally, this calendar was chosen because it was the most accurate system they could get the monks (who kept time back in the day) to actually memorize without error. -- ilyas \_ Every once in a while you'll see a leap second added. \_ Ok, that must be a latter addition to the original calendar. My mistake. -- ilyas
 2004/9/26-27 [Computer/SW/Languages, Computer/SW/SpamAssassin] UID:33760 Activity:high 9/26 What's the line for .forward to send incoming mail via procmail, and _then_ forward to a@b.com? \_ A .forward file isn't powerful enough for that. Do it all from procmail instead, by adding this to the end of your .procmailrc: :0 ! a@b.com \_ That will eventually create a mail loop that's not detectable by sendmail. \_ Erk, cool, thanks. Any way around this? -op \_ i use the following in my .procmailrc... if this can still create a mail loop, please let me know how to fix it: :0c: *!^FROM_MAILER ! a@b.com \_ Use something like this: :0f *!^X-Loop: yourname@csua.berkeley.edu | formail -A"X-Loop: yourname@csua.berkeley.edu" :0ac ! a@b.com Some comments: 1) there is no need to use locks since you're not writing to a file. 2) The "X-Loop: yourname@csua.berkeley.edu" header keeps track of whether this message has been forwarded before. 3) You can combine this with any other rules you have on your mind. 4) these two recipes must be listed strictly in this order (see the meaning of "a" flag). I have been using the plain "!" recipe without any checks before and got burned many times and as a mail sysadmin I have seen lots of users get burned by this too. The problems usually start when the b.com refuses to accept mail for some reason. Then sendmail will attempt to deliver the bounced message to your mail box. But since you have a procmail rule that tries to forward everything to the other host, it will keep forwarding mail until your csua account goes over quota. Your *!^FROM_MAILER rule might work fine for this purpose too, but it will fail to forward messages that were mail errors that didn't appear as a result of a failed mail forwarding attempt. \_ thanks! -FROM_MAILER guy

Are you sure you have no programming errors that eat CPU when the computer is being used or abuse bandwidth looking for other hosts to infect? What gives you the right to decide how my CPU is used or to keep it active instead of going into low power mode when idle? Are you going to pay for the increase in my power bill?

Am i missing the definition of good and evil somewhere in there? \_ No. \_ Well in theological terms, anything that comes from Satan is of Satan and therefore evil. All objects from Satan are evil. No objects from Satan are good. The correct answer in pseudo code is: while (getNextObjectFromSatan()) { print "Object is evil" } \_ Is this actually two questions? (1) a strategy for the man to be fooled about good objects no more than half the time, and (2) to "program a computer" to always be right? \_ No, you assume the man knows the strategy already, whatever it is, for S. -- ilyas \_ Once again, my problem with theory problems is figuring out what the heck they are talking about. \_ For this problem, substitute "ilyas" for "Satan", "theory problem" for "object", and "stupid" for "evil". Then make ilyas' goal to convince you that the problems are good.

I have about 10 jpegs (approx 20k each) and I wonder how many emails I need to seperate them into to send them to a friend with a hotmail account. \_ record all data to punch cards, load them onto a surpluss Oscar Meyer Wiener truck, and launch the whole truck to the destination using a giant railgun. \_ Never underestimate the bandwidth of a station wagon full of tapes. -- Dr. Warren Jackson, Director, UTCS \_ generally, asking a hotmail question on soda is a bad idea. here is a standard soda answer: write a shell script to send these pictures one by one using mail/mailx, eventhough I am not sure how to encode binary files in MIME format using commands \_ mimencode \_ mpack \_ Don't be a doofus. Put them on a web site and send links. -tom \_ You're a doofus, doofus. \_ Wow, the previous guy is like, a prophet or something. An insult and an answer that doesn't really answer the question! \_ Of course it answers the question. In fact, it's the correct answer to the question. If someone asks "how do I hammer in these nails with a screwdriver?", the answer is "use a hammer, doofus." -tom \_ Heh, that made my day. \_ Bad analogy, doofus. I'm not saying your answer was not a possible right answer, but it's also possible there is some reason that's not feasible. Unlikely, but not impossible. Also, there's no reason to be a jerk. You could politely suggest your alternitive. I suppose this anwers my question as to why everyone wants to sorry your account. -jrleek \_ The person has a soda account, so of course it's feasible. You might say there's no reason to be a jerk--I say there's no reason to ask stupid questions. -tom \_ And so he posts after the op already posted why he didn't want it on a webpage. \_ The op is still a doofus. \_ The op's reasoning is flawed. This whole thread is stupid enough that by MOTD charter section 7 subparagraph B the op shall be subject to insults until such time as the thread is gone. The fact that it's also about Hotmail is just insult to injury. \_ Hey, can I help it if people I associate with make the mistake of using hotmail for email? In the future, the first question I ask when I meet someone will be if they use hotmail for their email. If so, I just won't associate with them. -op \_ You mean injury to insult? \_ No, he probably doesn't. \_ I'm surprised anyone would even mentioning sorry in in this context! I agree with Tom - given the OP's posting, "why not send links" seems a very reasonable question... \_ That's what I'm saying, it IS reasonable, but you don't have to be a jerk about it. As for the sorry mention, that's referencing yesterday's discussion. -jrleek \_ so if you dont have a hammer available, you'd rather insist on using the screwrdiver, instead of getting one? \_ I appreciate the suggestion to put the pics on a web page. There are 2 reasons why I don't prefer to do this. I don't want the pics publicly available. And I don't want them on my web site indefinately. If I send a link, the receiver might assume they will always be there. But I will eventually take them off the web. So, good suggestion, but I still prefer to email them. So, is there anyone out there with a hotmail acct that can answer my original question? -op \_ There's another reason people might choose to hurl insults at you at this point. It literally took me less than 100 seconds to go to http://hotmail.com, look at the FAQ, and see that any email under 1 MByte total is fine, as long as it doesn't put the user over their total quota. So you're ok if the user is not close to having a full mailbox, since you want to send less than .5 Meg. \_ The FAQ I found on http://hotmail.com says there is a limit of 1 Meg for outgoing messages. I doesn't say anything about incoming messages (that I saw), but I vaguely recall that there is some limit to the number of attachments an incoming message can have. \_ All this discussion, but no answer to the actual question. I guess hotmail users don't post to the motd. \_ you could have frigging mailed the stuff already and not wasted so much time. Just email once or 10 times in smaller amounts. what the fudge is it? It is only 200k total. Send it in one email doofus. \_ send yourself 20 small jpg files and see what happens. there must be some reason you're asking this if you don't think this will work. \_ I don't have a hotmail account. It's easier to ask on the motd than to get a hotmail acct just for this purpose. -op \_ Better yet: open a Yahoo Mail account. Send the pix one at a time to that account. When all of the pix have been received by the account, send the username and password to your intended target. Yahoo gives more storage than Hotmail anyway.

I think India will quickly move up the ladder and be able to do everything. \_ pffft, why bother with India? Just take the whole thing to China. Much better trained engineers and they already do all the hardware manufacturing. Add in Taiwanese investment in knowledge and capital into the mix and we'll bury you dot head Indians. \_ you forgot about the language barrier. \_ There's no real language barrier since on the US side we don't talk to the grunt workers, only the 1 project manager. \_ developers that don't talk to each other? you'd better have a fuckin good project manager. \_ The developers talk in mandarin or tamil or whatever.

 2004/1/24-25 [Computer/SW/Languages] UID:11925 Activity:nil 1/24 How does one learn to get charisma? -engineer \_ My theory on charisma: You have a genetic glass ceiling for how \_ meaning, physical characteristics much charisma you can obtain. Most people function below this ceiling (either because it's too much work to be charismatic, or they haven't developed the knack). I think the best way is spend a lot of time around people and learn them, like you would learn a machine or a programming language. Learn what makes them tick, and what makes them happy. The way of charisma is the way of manipulating a complicated human machine. A lot of this knowledge will be subconscious and difficult to articulate, but that's how it is with lots of complex skills. \_ you're assuming he knows anything about computers or machines. \_ learning to spell first helps. nobody likes a dummy. \_ Nothing like a wise-ass comment about someone's typo that instantaneously kills charisma. If you want to attain charisma, learn how to speak in public. -williamc \_ i'm not the one trying to attain it. also, speaking well in public is only one of many parts that contribute to the overall effect. \_ In order to speak well in public one must be able to obviously communicate well. In order to communciate well one must be engaging (people are willing to listen to you in the first place). In order to be engaging one has to have charisma. Charisma is the most important factor in public speaking. Notice how charismatic individuals are elected to public office over less charismatic ones, often to the detriment of public policy. Note, I have said nothing about content, because content is very much secondary to the hoi polloi. Anyway, if you do not have it and you do not seek it, you are probably not qualified to comment on it. -williamc \_ no. it really depends on what kind of charisma you're talking about. a movie star might be described as being charismatic on screen; this means only that he's likeable and you can empathize with him. i wouldn't follow him into war though. there are other kinds of charisma for that; these usually involve conveying an aura of authority, which is often linked to physical and intellectual prowess. \_ we call that "other" form of charisma, "leadership" \_ Quaff random potions until you find the Gain Charisma one. \_ and there's that magic cloak, too! \_ ask your DM.

This happens to every job, sooner or later. Even doctors, plumbers, lawyers, etc. will eventually be replaced by Tajikistanis or robots. New jobs are created, and overall we all have more leisure--the average worker in a western country works somewhere around 8 hours, 5 days a week--compare that to 100 years ago. Where's the problem? -John \_ Big difference is that India and China are fucked up then. Now they are reemerging. \_ Their standards and cost of living (and wages) will rise, it's called the free market. At the same time, their demand for goods and services will go up. Currently, they don't have nearly as much of a market for the sort of stuff they're supplying "us" for cheaper as we do, hence "we" send the work over there. That will change, it always has. I seem to recall reading some article to the extent that a lot of Indian companies were worried about IT work moving to China for cost reasons, which is pretty revealing. -John \_ Some of us have rent to pay while your little global free market economy rebalances itself at the expense of the middle class. \_ No surprises here. If you haven't already started looking into other careers, now is a good time. Of course, I'm sure you all think that you're one of those blessed with so much talent that you'll never be hit by the continuing dismantling of the domestic software industry. \_ another career? nah, not only that, but another country too. give up software and high tech, and what do you have left, and how safe would those be? \_ The source is Forrester Research, the same people who predicted in 2000 that by 2002 the market penetration of personal video recorders would be in the same ballpark as that of washing machines. Keeping your options open is always good, but I don't think the verdict is quite in yet. \_ looks like a new career should be statistical research & prediction, then. \_ Five counter trends are: (1) less H1Bs, (2) fewer students in \_ fewer CS these days, (3) Indian and Chinese software engineers moving back to their respective countries, (4) rapidly falling dollar narrows the gap a little, (5) rapidly rising cost of living in say China. \_ and these are reasons why it will take 12 years for it to fall 33%. Without these mitigating factors, it would fall faster. And oh, btw, the biggest counter trend is probably the growth of the software industry as a whole as the presence of computers and technology permeate more and more of every day life. \_ This will start happening to System and Network Admins, too: http://csua.org/u/5bg \_ I highly doubt that this will happen. From my experience it's practically impossible to outsource sysadmin. You still need to be physically there when the server goes down. I've seen many attempts at just remote sysadmining and that never works. I also find that at least half of sysadmin is help-desk, so unless you want users to start calling India everytime they can't get something to work then I don't see the trend. However, I do see the trend in possible consolidation. I think there are many small/medium sized firms who don't need a full-time sysadmin, and what they need is a firm which will contract out sysadmin work. Overall, I think that there will be much less local programming work, but there will be more computer support work. As for programming, it doesn't come as a surprise to me. It's relatively easy to learn programming (especially enterprise stuff in which you typically just populate datastructures from forms), and with the predominance of 4GL languages now in the field this is even more so. Another high-tech area that will be greatly hit will be layout designers for chips (place and route software will kill off custom layout) and probably circuit designers will just all be off-shore instead of being H1Bs. \_ Locally outsources sysadmins? Having a helpdesk across town is no better than having it in India. That's not going to work. \_ It certainly will work. Someone across town can come in twice a week for system maintenance and be there for emergencies. Try that with a Punjabee.

The program doesn't exist yet, but the "all" is actually real. The idea is that you want to find bounds on a certain number called Chaitin's omega. If you know something about that number you can solve lots of problems. In fact, if you know that number precisely you can solve any problem which can be precisely stated. You get lower bounds by simulating programs until they stop, and you get upper bounds by searching for programs that print certain strings. -- ilyas \_ didn't you learn in high school to take "all" with a grain of salt? i guess not, since you never learned to format either. \_ who learns to format the motd in high school.... \_ I had that in class. \_ Duh.

 2003/11/3 [Computer/SW/Languages, Computer/SW/OS/Linux] UID:10911 Activity:nil 11/2 From Eric S. Raymond's website: As an American and native English-speaker myself, I have previously been reluctant to suggest this, lest it be taken as a sort of cultural imperialism. But several native speakers of other languages have urged me to point out that English is the working language of the hacker culture and the Internet, and that you will need to know it to function in the hacker community. This is very true. Back around 1991 I learned that many hackers who have English as a second language use it in technical discussions even when they share a birth tongue; it was reported to me at the time that English has a richer technical vocabulary than any other language and is therefore simply a better tool for the job. For similar reasons, translations of technical books written in English are often unsatisfactory (when they get done at all). Linus Torvalds, a Finn, comments his code in English (it apparently never occurred to him to do otherwise). His fluency in English has been an important factor in his ability to recruit a worldwide community of developers for Linux. It's an example worth following. \_ Ok, I think most of us knew this but even if not, what's your point? Was this supposed to be educational? Upsetting? Bait? I'm willing to play along, I just need to know my role. Thanks. \_ I'm just sick of people posting to the motd in broken English, and then bitching when people call them on it. See below. \_ you know, if you are critical of ALL grammatically incorrect post on motd, I wouldn't bitch as much. Yet, you, like good number of others, selectively tolerate one form of grammatic error, while critical and censoring another. If you think my grammatic error is somewhat inferior than those improper English posted by the native speaker or European decent, then, please go fuck yourself. \_ You know why it pisses me off? I'll tell you. It's because I work with fuckers like you. I've worked with plenty of people who can come straight over from PRC and speak and write clear, understandable, if slightly stilted English and can always get their point accross. Then there are people who no matter how long they're here, their English is always not just bad, but actually a danger to those around them. When you're working with things that can kill you, you don't want to wonder wether the guy next to you is going to be able to communicate in any useful way or not. I have learned by dealing with fucktards like you that the *reason* that some poeple in engineering are like this is not that \_ people (learn to spell you moron) \_ Ooh, the previous poster writes a 290 word diatribe, makes a typo in "people" once out of four times, and you call him out on it. Congratulations. Oh, and it's "Learn to spell, you moron." they are from one country from another or that they are dumb. It is an arrogance that infects the culture of engineering like a cancer. That arrogance assumes that if you are good at book learning you don't have to be able to communicate. These people are always second rate engineers anyway, because their work is no good to anyone if they can't communicate. Every nation in the world has jackasses like this, including of course, the US. The difference is that fuckers like this who are from other countries are just easier to spot and pose a bigger physical danger in an emergency. And yes, I can speak Mandarin better than your English, and no, I'm not Chinese. You can cry "racism"! all you like here, but when you go back to China and don't ever get promoted because of your shitty communication skills, don't blame Cal. At least one of us tried to straighten your dumb ass out. \_ I work with people from China, Russia, Korea, and Vietnam all day - but the worst English writing comes from the American-born-and-educated "native" speakers in our group. \_ Nope. I work with people from China, Russia, and Vietnam, and they can barely communicate. It drives me nuts. \_ Dude... I am not the original poster, but I have this to say.

 2003/5/12 [Computer/SW/Languages, Computer/SW/Compilers] UID:28412 Activity:kinda low 5/11 What is "software pipelining"? Is that like multithreaded stuff doing the same task on different processors? I understand hardware pipelining completely (took cs152), but don't understand what software pipelining is. ok thx. \_ It's a way of reducing loop overhead (much like loop-unrolling). SW pipelining works by taking replicating the loop body several times and staggering them in such a way that the instructions appear in reverse order in the loop body but none of the instructions have any dependencies within the same iteration. This helps place distance between dependent instructions. The major problem with SW pipelining is that you need a really smart compiler to realize this and there's some startup and cleanup code you need to tag on. Original Code ------------- L1: lw $1 <- MEM add$2, $1,$1 sw MEM <- $2 bc L1 SW Pipelined Code ----------------- lw$1 <- MEM add $2,$1, $1 lw$1 <- MEM L1: sw MEM <- $2 add$2, $1,$1 lw $1 <- MEM bc L1 sw MEM <-$2 add $2,$1, $1 sw MEM <-$2 \_ so does this require VLIW (issueing 3 cmds in 1 cycle?) \_ I wrote it in column format to illustrate how to convert the original code into SW pipelined code. It has nothing to do with multi-issue. \_ Multi-issue helps. There's two big reasons to SWP. One is to take advantage of more instruction-level parallelism (ILP), because you're running more instructions concurrently. But even if you don't have multi-issue, you can still get better latency tolerance by interleaving instructions from other iterations while waiting for a long-latency instruction to complete (in the example above, the load [lw] might take a long time to return). \_ one way people use the term is in threaded programming models, where you have a thread (or pool of threads) to handle a specific task which then passes work on to another thread/threads. \_ comment on my reply, the above poster has the more common usage.

So for 8"x10" you need 2400x3000. But that is only if your image source is of high quality. If you only have small prints to start with, there's really no point to scan, say, a 4"x5" at 600dpi and then print it at 300dpi to 8"x10". The final print won't be good anyway. \_ Printing is best at 300-200, but I've gone below 150 and still had acceptable results for some types of images. Scanning prints however tops out around 200dpi, so you can't scan a 4x6" print to make an 8x10" with any level of quality. -jor  2002/10/1-2 [Computer/SW/Languages] UID:26065 Activity:high 9/30 How do I get ps to print the complete command line of the job without resizing my terminal?

The "audit" is not the problem. Its is corporation which is the problem. Auditors take numbers that corps given them and sign off that the "accounting" is correct. Auditors don't look at actual invoices and costs and put the money where is really should and compare against what the corp said. Most auditing is just proceadural bullshit which investors/public don't understand. Like when an audit occurs it starts with an operating procedures guide, the auditor reads the OSR (operating proceadures) and then spot checks the procedure- THEY DO NOT check the numbers- the idea is that if procedures are followed than numbers are accurate. For instance you read a lot about how boards of directors signed off on a lot of crap which they should not have. The auditors job is not to check to see if the crap "should" have been signed off on they only make sure that is "was" signed off on as that is what the procedure calls for and that is all the audit requires. When I audited time sheets for DWP (department of water and power), I only had to make sure that timesheets were signed, the work accomplished and the hours worked were irrelevant and not checked in an audit. It was not my job to verify that the work completed had anything to do with the northridge earthquake- it was only to check to see if the time card was signed by supervisor as that is all the proceadure stipulated. So although I have never been involved with a full blown audit to see all the little pieced which go together- I have an idea of how they work and have known for a long long time that they are just bogus and do not actually verify if the numbers were correct. As I have written previously when I reviewed Level 3 books I found 700M in double booking or not accurate booking (exactly what wcom exposed). What we did was just instead of reporting the error we just slowly worked the error off the books by doing 150M adjustments now and then and no one was the wiser.  2002/6/13 [Computer/SW/Languages, Computer/SW/Unix] UID:25082 Activity:low 6/12 How do I do this in sh -- I want to send the output of foo to "| grep" and the standard error of foo to /dev/null ??? \_ foo 2> /dev/null | grep  2002/5/3-5 [Computer/SW/Languages, Science/GlobalWarming] UID:24687 Activity:high 5/2 Math people: if I have a password generator that doesn't generate any collsions in 1,000,000 runs, is there a way to estimate a lower bound on the size of the space with a certain confidence? \_ yes.

Go to any CS school and find out how many kids have done any SAP programming. See how many have experience configuring the HR Module of R3 plus knowledge of the HR industry to be able to interpret what the hell they are configuring..... you just can't find anyone-- but this is the skill that is in dire need. This field does not have the flexibility to relax constraints. Most other fields have life cycles of decades and thus employers can afford to invest in training; however, the nature of (fucked up management running fucked up companies screwing american culture) the business forces employees to continually swap out of jobs in effect becoming contract workers. This emerging culture ultimately puts even more restricutions on skill sets required by corporations. Right now we live in a world that is infested with bad management and CULTURE. The prevailing attitudes and GREED are bad for the economy unless they themselves are constrained. This is much akin to the idea of liquidity constraints in economic systems. With laize fare liquidity individual agents consume a high level that what would be socially optimal. Thus a very valuable tool in the economic toolkit is that of liquidity constraints ( ie low credit for young - higher interest rates for those with little credit etc. ). A corrosponding SOCIAL tool is also available. Traditionally this tool has been found within RELIGION which contains inate constraints of consumption and perceptions of the environment. In a new age economy where religion no longer plays a role new instruments of social constraint need to enter into discourse. Some suggestions are longer term employment contracts (ala Japan), Other interesting factors to note is what is called adaptation level or AL. In AL theory agents make a fundamental mistake in judging preferences and level of satisfaction. Agents compare to what is called a common set. This common set is the group of individuals with similar skill sets. In its raw form the common set is the caste of class society. An error made by agents is the inaccuratrely percieve well being based upon their common set instead of the global set. This error leads to some extreme implications, Namely that (using a early 1970's example which is obviously a little racial) northern blacks are more likely to riot even though there belief about there future fincial prospects is higher than southern blacks. The corrlation to the CS field is that people in the industry have made fundamental errors in judging themselves against their common set instead of the global set. This required change in perceptions can only come from carefully construction government policies and corporate incentive and HR policies. Additionally this required change is of a socail nature and thus the time before any results could posibliy be seen are years away.]  2001/12/15 [Computer/SW/Languages, ERROR, uid:23252, category id '31298#8.23' has no name! , ] UID:23252 Activity:high 12/14 i've been contemplating a serious career change, back to teaching english. maybe not in the same form. i've been how in japan there hasn't been enough people with computer skills to handle the job requirements so maybe i might try something like that there. but today really disturbed me. at work two of the senior guys were talking about "weeding people out." i think the thing that got to me was the tone that they used. it was snobbish and elitist. it got me thinking about how the industry works and what's been going on. it's pretty sad actually. there's quite a bit of arrogance on behalf of computer science people. then i read an article over on slashdot which discussed how computer science people wanted to be laisse faire regarding policies in government. there's obviously this double standard/paradox/oxymoron that is going on that's really irking me. the thing it seems is that computer science people are these ayn rand clones that believe they can live in a world of their own and as long as no one disturbs them they won't do anything. but the thing is that's not realistic and far too egocentric in thinking. it sucks that there are people in CS who do it for the money or don't have as sincere of an interest in the field, but people have to eat and live. that's just life. the problem with that mentality is that it still creates an elitism, a social divide that does affect people. i've seen people at interviews that have kids and need jobs. maybe they aren't the best people for the job, but you're not going to get perfection. i dunno. it really sickens me to hear that. i've become so paranoid that i trust no one at this point. i suspect everyone of doing wrong and being the enemy. it sucks. the thing that's really sad is that i like computing. but it's the people that fuck it up. same as music. i like metallica's (old) music but i hate them. i'm starting to think the whole net thing is going to end up being like the ending of jurassic park 1 where everyone, especially the chief scientist, realize that it's something that man shouldn't handle because he's incapable of the responsibility. so the secret must be hidden from man until he's ready. perhaps the net revolution will collapse on itself as it seems it's doing until it's only utilized by researchers in universities again. \_ Now _THIS_ is a troll.

Mine more clue. \_ Usability testing is a far different realm than statistical sampling. Many usability tests have only 5 or 6 participants. Don't worry, the people in the Nielsen Norman group know far far more about usability testing & statistics than you could ever hope to - they've created many of the techniques and wrote the papers & books and designed the products to back them up. (Much of the modern GUI is based on work Tog did at Apple to refine the original Xerox designs and millions of websites are based on Jakob Nielson's design strategies.) \_ Not the point of the question. I was trying to get at why isn't statistical sampling typically used in usabliity studies? Just because usablility tests typically ask a small number of people, it doesn't make it right or statistically valid. Sure cost is an issue but that doesn't mean that you can just make conclusions up after sampling a (usually) small number of people. BTW, I know who Nielsen is. I used to sit across the hall from him at one point. I asked the question because it has always bugged me that he almost always uses sample sizes smaller than seems right.

Thus, high- performance, floating point multipliers often do no handle denormalized numbers, but instead trap, letting software handle them." \_ Don't you always multiply the mantissas as if they are integers and then add the exponents, regardless of whether they are normalized or not? \_ normalizing a floating point number means shifting its mantissa to the left until the MSB of the mantissa is 1 (and compensating by changing the exponent). if you know a number is normalized, you don't need to store the 1, which means that assuming normalized gets you a free bit. however, being a certain number of shifts, when the exponent gets as small as it can get, you can't shift any more, and you might be forced to use a denormal float. this is only a problem with very small number. typically, hardware will throw and error when it can't normalize. good hardware doesn't and just says lets you know that something is a denorm. -ali. \_ That's easy.

To the responder, show me a definition for how \_ 64-bit Unixes define int as 32-bit & long as 64-bit. little endian and big endian machines store 64 bit entities. the way i'd do this is use what he has up there, but at the beginning of my program, write a routine that asserts that it's the right way of doing it, and abort() at runtime if it's not the case. \_ #ifs \_ don't you mean independent? \_ if they are unsigned, can't you do (a*(2^32))+b \_ This is equivalent to the code above; both work. or if you need it to work in every situation, you need to look in limits.h to see the true sizes of an int and a long on your system, as well as endianness, and work it for the different situations, have fun. \_ Well, not true. On a big endian machine, if shift left a long (which was promoted from a 32-bit int) wouldn't the lower order bits fall off the left side. A perfect solution would be to barrel rotate one of the numbers and OR them together which will guarantee that it will always work but I know of no barrel rotate function in the standard C libraries. say you've promoted ABCD from 16-bits to 32-bits. - big endian: 0xDCBA0000 << 16 = 0x00000000 - little endian: 0x0000ABCD << 16 = 0xABCD0000 \_ You moron. First of all, that's not promotion, that's reinterpretation of bits. Second of all, endian-ness works on the byte level, not the nibble level; so the first byte of a little endian 0xabcd is 0xcd, not 0xdc. Big endian systems are intolerant of lazy casting. That's where your problem lies; it's not with the shift operator. -pld \_ You moron. You've mixed up big-endian and little-endian.

The lower order bytes (CDAB) are one the right side for order bytes (CDAB) are on the right side for a little endian machine so it should be the other way around. \_ Have fun the next time you look at a memory dump -pld \_ This is incorrect. shift left treats the entire int as a unit. The high order bits fall off, regardless of endian-ness. You need to go read K&R again. \_ Size of int is NBPW*8 in sys/param.h, or simply sizeof(int)*8. BYTE_ORDER is defined in machine/endian.h.

I'm using union { double x; long y; } and then shifting iteratively with a value.y >> i and then masking it with a value.y & 0x1 but that doesn't seem to work. Any suggestions? \_ first problem: a double is probably larger in size than a long on your architecture. are you sure your compiler is doing ieee754 doubles? what you described is very dependent on what you're using. \_ printf("%08x\n", * (long *) &x); \_ printf("%qx\n", *(long long *) &x) is what you want on soda, where a double is 64 bits and a long is 32.

 1998/3/18-20 [Computer/SW/OS/FreeBSD, Computer/SW/Languages, Computer/SW/Languages/Perl] UID:13830 Activity:moderate 3/18 Has anyone (else) encountered a bug where after using lseek with a negative offset read stops working on that fd, even though a valid off_t was returned? In particular, I have a file with two binary unsigned longs at the end, and when I do an lseek(fd, -2*sizeof(unsigned long), SEEK_END); the reads then fail. -mel \_ Use PERL. \_ Did you try seeking to the beginning to the file, then a forward seek to where you want to read as a work-around? \_ The file is full of longs and I had wanted to read the two longs at the end of it. The workaround I found was: end_offset = lseek(fd, 0, SEEK_END); lseek(fd, end_offset-2*sizeof(long), SEEK_SET); which is ugly but it works. Throw in a few error checks on the return codes and it should work for you too. -mel \_ mel you ugly squint, get off the motd \_ And now, the right answer: You are specifying a seek relative to SEEK_END... Such a seek is implicitly in the negative direction, since it's impossible to seek past the end of the file. The minus sign in front of the 2 is unnecessary. So you should be doing: lseek(fd, 2*sizeof(unsigned long), SEEK_END); I tried looking for an example of this in K&R, but in each instance where SEEK_END is used, they demonstrate with an offset of 0, which is not too instructive. WHY HAST THOU FORSAKEN ME, K&R? I TOOK THY WORD AS GOSPEL ONLY TO FIND A HALF-TRUTH LYING IN WAIT TO SNARE THE UNWARY! -mogul (hey, it's 3:15am, fuck off!) \_ Not quite. A seek from SEEK_END is not implcitly negative; just like SEEK_CUR and SEEK_SET, positive offsets go forwards and negative offsets go backwards (see lseek(2)). The problem with your code (and it's not really your fault) is that sizeof returns a size_t, which (on freebsd) is an unsigned int; when you multiply that by -2, you get another unsigned int (K&R 2.0, p. 198); and the unsigned int (0xfffffff8) then gets promoted to a signed long long (0x00000000fffffff8). This is not what you want. The Right Way to fix it would be for freebsd to make size_t an unsigned long long, but that would break a lot of stuff and probably won't happen soon; in the meantime, you can cast the return value of sizeof to a signed int and your code will work. --mconst
