but when you multiply the answer by 1.7, it goes back to 1. well from my understanding of the problem, if you do multiply it back to 1.7, then you will get a different answer because of the rounding off errors. isn't the rounding off suppose to happen when you are at the last digit of great decimal places compared to the one discussed in the article with error in the storage? i mean trying the 59 + 12.5% yields the correct answer. the calculator does not display the errors. is it a problem with how i understand the problem?
pardon my ignorance but why does the problem exist today? can't it be fixed? what is the actual effect to us (since in the forum, the examples given in the article are false)? (links will be helpful.)
when i use my calculator, it doesn't give rounded off numbers. i suspect lots of programs will have problems with rounding off but i don't seem to notice it. is it that insignificant?
i just want to give some reactions. i don't live in the us or china.
China's lack of laws are unethical.
How about legalizing laws that promote the rich and the elite, isn't that the same?
Does that make me better off?
well isn't saving $270 good? i'll go back to the first issue, if you have the laws, why don't you have laws that promote domestic trade and avoid the big deficit?
China is an evil regime.
so is the usa a good regime? i just like to ask that if you mean good = legalized and not in a moral sense. so like engaging in the war with iraq is good because it is legalized. can you say that the usa did a good job in making the lives in iraq a better place than in china now?
but then again, what government in the world is good (clearly there is some form of oppresion and corruption in all?) but with regards to free speech and rights, how do you define free. is free doing whatever you want or free as in doing with responsibility. if you are arguing free as in whatever you want, then i can say that i am not free in the usa as i cannot do whatever i want. for free with responsibility, i'd like to sample the reluctance of the usa for their participation in global environmental protection efforts (hey, it's my earth too.) but as a consolation, its comforting to think they are getting the brunt of their actions or lack thereof by increasing severity of heatwaves and droughts and major hurricanes and floods.
They can treat workers as good or bad as they like.
well in the usa, it's the same. just look at the enron and worldcom collapse. it's just a "more humane" way of doing it.
i don't like to engage in a flame war. you know everybody has its share of bad things, its destructive to think that nothing comes good from things. i respect your opinion too and there are lots of things i can say are good in the usa than in china. but there are also lots of things good in china than in usa.
i am an hsbc customer and have access to internet banking. though i am not uk based, aside from the regular username and password, you will have to enter a six digit number generated by a token given.
this is a different method from the one mentioned and will probably have no effect against key loggers. although i read somewhere that phishing sites are now able to mimick a bank website and instantly login to the account as it is phished. however, the main feature that the bad guys forget is that account transfers are not permitted if the destination account has not yet been enroled (even bills payment i believe.) in other words, i must strickly go to the branch and fill out a form to allow money transfers to a particular account. so it will be a no go if they will siphon everything in my account (though they will be able to see transaction history but i don't think they will spend that much time and effort figuring out a pattern.)
the supercomputer is quite cheap. they can probably sell a lot of these machines and will sweep the top500 list. however, it mentioned that the processor is specialized in doing astrophysics calculation. i am not sure if this will be useful for other fields.
but the good think about it is that it is more energy efficient. it seems the trend in desktop/servers right now are also going to the supercomputers. maybe they could include a performance per watt ratio in the top500 list as well.
well i guess some of the genes that we have programs ourselves to die. just imaging if nobody would die today. i'll just image chaos in the world due to scarce resources. going to the lemmings path?
well i guess if amd cannot win technically at the moment, they fight legally. i seems they've been launching antitrust suits left and right. hmmm... is amd losing its focus and using legal tactics instead of better engineering (not that i think intel did not violate any antitrust laws)?
well i beg to differ. the core 2 has a better architecture now. just see how anandtech is able to overclock (air cooled) to 4ghz with just a good cooling system. without doing anything, intel will be able to release faster processors as amd tries to tweak itself out. right now, amd processors are slow to ramp up their clock speed. now who is having problems?
well anandtech has a benchmark for the woodcrest (xeons) vs opterons.
and the xeons wins even though they don't have the hypertransport bus. the latest 5000p server chipset is quite good. it has two cpu busses (one for each socket.) good memory reliability features (sparing, mirroring, etc.) and hosts of other stuff.
we're off to ordering these woodcrest systems already and plan in replacing all the servers we have with them.
i would like to say congratulations to the engineers who designed it. (it's been a dream of mine to create a next gen microprocessor.)
i'd like to elaborate on designs: 1. low memory latency - given that they are not using integrated memory controllers, the core 2 latency is lower than amd. the transition to fb-dimms also provide higher latency that is still overcomed by the architecture.) 2. low bandwidth utilization - increasing bus bandwidth does not increase the performance of the processor significantly (as in netburst.) there is no bandwidth cotention given that it is dual core (compared to previous bus limited dual xeons.) i just wish that someone would be able to provide benchmarks for an underclocked bus to be able to see the actual utilization of the architecture. 3. highly efficient cpu - the execution of commands is well thought of. the concept of the macro/micro fusion amazes me. branch prediction is highly accurate. and the prefetch does a good job of avoiding idling the cpu (resulting in 1 and 2.)
for those working on the manufacturing process, congratulations too. here are my reasons: 1. low power consumption - best performance/watt ratio 2. highly overclockable cpus - anandtech reports that it is possible to run it at 4ghz in room temperature using air cooling
i just hope that everybody improves (mainly amd and intel) so that all of us consumers will get better products at much cheaper prices!
since many people already mention that you are paying for the content as well as distributing it, why not put a reward system for the seeders.
a particular gb, let say, will allow you to convert it to credits used to pay for new movies. seeders and wb will be happy. i'm sure there will be a lot more of leechers than seeders.
i didn't rtfa. i think putting an online ups and generator will be far cheaper and better than trying to rely 100% power supply from your utility. i think that cost of equipment + overhead transmission underground transmission.
it will be crazy if critical infrastructure (hospitals, telephone exchanges, etc.) will assume that utility power will be reliable 100% of the time. it may even be better in some areas to actually run of generators 24 hours than having to get it through utility. these scenarios don't justify spending too much on underground cables as cost outweight benefits.
why not use dram especially in these sensitive items? when things go bad, power will be cut and data will be erased. but can data be recovered from memory after power has been removed?
anyway, for the hdd, is modifying the content of the file better than erasing it? for example, you can binary edit the file and insert random data into it. at least even when the hdd remaps certain parts to other areas of the hdd, data will appear to be random. or why not create a virtual drive from a full file of an existing harddrive, will this make it harder to recover data? and lastly, why not encrypt the files instead? i'm encrypting my important files to a virtual drive (supplied by ibm/ultimaco.) though i am not sure how difficult it is to get access to it.
i would like to at least give credit to him for his humanitarian contributions. i read earlier from a website (i cannot find it, but i think it is something from cnn or forbes) that he gives a lot compared to other billionaires. they made a ranking that if these contributions were included to his net worth, it will increase the different from the richest guy to the 2nd richest.
i haven't heard (maybe i'm not listening that much?) of other persons contributing especially in the tech industry. though they may contribute, but i guess not at a level with bill. since when did you hear rich guys of oracle, google, yahoo, sun, cisco, etc did contribute a lot? though i am just guessing, probably bill is donating to the others combined.
here in slashdot, with probably higher salaries of readers, how much money has been contributed to the betterment of humanity?
* well i am talking about the person here and not the company. bill != microsoft. this is where i give him credit.
the problem now is that phones are getting more complex. this complexity makes their reliability suffer much like a regular windows phone. i remember the earlier phones where the purpose is just to call and you don't have to reboot or the phone suddenly stopped working.
i am not sure if linux will be helping but i hope they will get reliability right. my phone now locks from time to time and needs rebooting. there are times when applications crash (though a reboot is not needed.) but it is quite annoying and a hassle.
hmmm... may nsa has already colocated their sniffing equipment to check for queries made by people.
probably nobody can confirm or deny that this is going on with google. everybody things here in slashdot google is a saint. but i don't find them different from att, et al.
i think the possible reason behind this is that they have already invested so much with supporting windows. when you look at their software (thinkvantage), it's quite amazing how much they are able to take control from windows. for example, the rescue and recovery service partition is from a customized version of windows (they are able to make windows run from a single cd-rom disc.) on top of that, they are able to change the login and security of windows beyond the regular such as integrating fingerprint and password manager (i don't login using the regular windows xp login screen, the interface is from their software.) they can also secure the system with passphrases and integrating it with their security chip.
they have already made lots of utilities for windows. i think it will take a big investment for them to port it to linux and support lots of distributions around. right now, it might not make financial sense for them to do that.
my question is that when in movies, if it is rated r-18 (restricted as far as it goes for me,) then people watching below the age of 18 are prohibited from doing so. reasons for the restriction may include violence and sex.
for the video game side, people are saying that there should be no rating (or if there is, mature ratings can be sold to young people.)
i'm just baffled as why it is ok for the movies and not ok for the games. it can either be the movies and games both ban sale depending on the rating. (on the basis of moral grounds as argued by people.) or ratings in movies will be removed and everyone including kids will be able to watch those restricted films. (on basis of free speech as argued by people.)
the problem is with warranty drives. i cannot return them the drive that has been squished or made into small pieces. i don't have a very very strong magnet sitting around the house so that is no go.
anyway, i just had to replace my laptop drive this monday by ibm. i have the set security on (finger print, passphrase, harddrive passwords, windows passwords.) my question right now is if they will be able to access the drive even though i tried to secure it. confidential files in windows have been encrypted but regular docs are not encrpted though. i have activated fingerprint, etc. am i relying too much on the security features?
the technical support person told me that they will be destroying the drive after receiving it. i'm not sure now if they will reuse the drive. hmmm....
note, their support was surprisingly fast (they delivered the replacement drive to my doorstep less than 3 hours) for me to be able to totally delete the drive (i was backing up the files.) i had to return the defective drive back to the delivery guy. i didn't pay for any extended or priority warranty service.
i would want some company to power thin clients using poe switches (with around 5 watts usage as not all switches are able to implement full 15watts power at all ports.) it will be very good for us it people managing an entire company as we can control the network port and easily avoid problems from the end side. not to mention, easier to provide uninterrupted power.
from the power, the cost should be very very cheap. something like $50 (if possible.) the barrier to entry is expensive since price is like a desktop pc and having the actual server itself - 2x total cost. (of course this is not tco but your actual cash outlay affects your ability to implement such situation.) you know, wii is to ps3 and xbox360.
for hardware, why not have an xt processor, 8mb ram, video, and io (i believe all of these can be built in a single die for very cheap manufacturing and integration.) you don't even need the flash memory as i would want to do network boot. with all the remote processing, do you really need that much speed?
yup. i'd like to think that sony and microsoft is trying to sell the latest gaz guzzling suv with all the features making the drivers 'king.' nintendo is those new japanese car makers who really focused on more environment and practicality. guess who's winning now?
as it has been said many times before, i believe the console maket will shift as well.
