people have been eeking out performance out of ARM cpus (ipaq is just a strongARM clone) for a very long time
since the ol acorn in the corner of this roomcan atest to
did a space invaders clone when I was 15 should dig that out (-;
really you should look at the GBA as its the same ISA but instead of a pultry 78MHz on GBA its a whooping 200Mhz on the IPAQ
equate that with moveing from a 486 to a P200 and you get the idea !
(yeah yeah not the same, RISC, improved piplines.... give it a rest I know already)
should be relitvly easy to do a GBA clone on the IPAQ as its the same ISA why havent we seen this before ?
ok lets get this straight patents are different than copyright !
when you say that "most of my collection is in MP3's since much of my music was encoded by others" does this mean that you have fair use ? have you bought the music and now just have a copy of that music that you bought made by another in MP3 format or have you got a stash of napster/gnutella/friends shares & downloads because if you have not paid then you are breaking the law
(hey in my country it's the law I don't know about yours don't mod me done because of it)
while a lot of so called patents we talk about here are ONLY recognised by U.S. patent office, its really quite silly.
say I produce a product that creates wizzynewformat and that is protected by a U.S. patent I can then sell my product in my country and they have no claim on me in fact they can go jump !
now web standards are global, say in china a company adopt a standard that in the U.S. others have to pay for they can sell it cheaper than other U.S. firms and simply all the content is created in china because its cheaper
how you enforce this so call patents is the problem because well a lot of people don't accept them at all
much of the intresting things about networks has been done through live capture of a system and then sifting the data
phone networks work well because they have had a long time trying things out and finding optermal solutions to random problems that come up in live networks (problems with GPRS networks where only seen once semi live)
also you dont get the scanning and general attacks that do strange things to routers
its like saying yep we have 1000 monkeys and typewriters but we need you to go through the data and compare it to the real world
you might as well do it in the real world how expensive is a switch/hub and network cards ?
this was told to me on a punt (a boat) by a Cambridge student and they lie with the best of them(most spies came out of Cambridge) anyway the story goes Newton designed/built a bridge over the river cam in Cambridge
It had no bolts and held together with gravity
Students could not work out how it worked
One night pissed they took it apart to find out
And they could not put it back now its held with bolts !
bridges are fun no matter how much tech people get them wrong witness the London millennium bridge
(it swayed so much you could not walk over it !)
Examples such as the FBI having misgivings about mobile phones and crypto
(GSM includes a simple hash which while easy to break the FBI like their plain scanners)
and US politicos asking for back doors in algorithms
(while I can pick up AES or serpent which both do not have US involvement)
you can get crypto and use it rather simply
how do people think they can make me give it back ?
e.g. in the U.K. they say that you can use strong crypto but when asked by a court you must give over your keys or go to jail for up to 19 years !
What they dont say is that the law has yet to be tested, there is a wealth of past history where people have written in secret diaries and they cant make them decode it and these people are not put away under this scheme.
(so IMHO it will fall on its face and I am not giving over any keys !)
my question is what is the stupidest thing you have ever heard of ?

yes I think that there is a lack of servers you can build yourself
companys often want to run servers on their intranet and dont want to far it out to a outside source (palm sells alot of their enterprise servers which do syncing)
personally the only app that runs this well and gets messaging right has been Lotus Notes Domino
frankly it rocks and I am surprised that Ximian have not picked up on this they have a client but no server and the server is where the money is !!
oh yeah did I mention that PA-RISC is a MIPS decendant
but shhh they made so many changes they fscked the pipeline(they might have got it working again but I dont know any more)
may the SPECINT and SPECFP fight it out
regards
john jones
p.s. I wonder what the HP layout guys think of Intel chips (-;
one of the great things about lotus NOTES was the SERVER
you had revision control and ACLs + logging for documents/databases which could be exported as basic HTML
keys and directory's(phone books) stored in a nice central place
Plus SYNCing of documents/databases/email/directory's
That was really nice
yes there are products that do this now but you have to kludge them all toghthter and admin is still a bit of a nightmare (OpenLDAP, procmail and zope)
what they should do is use and XML backend (publishing becomes easy) and LDAP (phone books + auth through a PAM module) combined with a IMAP server which understands OpenPGP that can sync to other servers set up around the world
lots of documents are placed on the corp intranet but they are spread all over the place geographically speaking what would be cool is of it could figure out you are in say France and pull over a copy of that dept intranet who is in US and then next time someone asks for it when they are in France they get a response straight away
anyway hope their client (eventually) will work with lotus notes
can you read ?
(insulting I know but I'm sick of this)
read my comment and pay attention to what I say about military airports and planes
I have got sick of people on slashdot recently unable to read comments and have the feeling that VA Linux staff do 98% of the moderation
did you not read the part about F18 simulation and Military airports being classified ?
but civil NOT being
its sad that the people of the US say they are open but in fact the government agencies contract out all the work and so then it cant be open
regards
john 'bad mood' jones
p.s. oh and I stuck in the citizen of USA bit so that fools would not complain about me not being and harp on about national security but that failed didnt it !
test and code it on more than one arch say PPC and x86 running linux and maybe even have a go at getting it to run on solaris
(alot of uni hardware is sparc solaris so think of all the profs willing to play;-)
you can download Solaris for x86 for free or get it on CD for shipping costs
(this reduces the amount of hardware that you need)
once its running on this the sparc is just a differant set of compile switchs in that big ol makefile
question why don't the US military/air force open up their simulators ?
I thought in the good US of A that all projects that the government does the people of the US of A had access to the source
Unless
It was deemed that it was endangering security of the nation
Or
It was contracted out to a company and then they had all the IP
I don't see how a simulator could fit into any of the above
The dynamics of a fighter plane YES but not a Cessna
The military airports YES but not civil airport where the data is already published
Since the MS flight sim is ahead of most things what have you got to lose in asking ?
(Politely since the Military don't like question right now)
regards
john jones
p.s. I am not a citizen of the USA so am just wondering
in a company what do you want from your crypto system?
1. The ability to send secure messages to customers
(relating to billing or just giving instructions about product that you don't want anyone else to know CUSTOMERS demand that it be secure)
2. send messages within the company that can be read only by receiver
(prevents leaks and makes sure that the whispers don't start up e.g. how many mails go to the postmaster )
3. escrow is needed when an angry employee leaves and you need to read their work
(the world is full of jerks and they can be hard to spot)
4. Key servers need to be up to date and manageable
(from a sysadmin point of view)
5. Standards for sending e-mail securely and product activation would be nice
yes its good to be open but some one needs to productise this so that company can buy an Complete Off The Shelf (COTS) solution that a company can buy because not enough people do secure themselves IMHO
are their anyone that fancies boxing up GPG, a keyserver and manuals on how to do the above I am sure that they could get some money from companies I know
Which is what they use in the new RIO and the Game Boy Advance (GBA).
So the potential is there to create a clone of a GBA (but without carts).
This would see you download your game to phone so you could have a library of games that you have paid for and when you want a new one you pay for it and it becomes part of your library (reducing the number of games that can be stored to1 save the amount of flash and so how expensive the end unit is ).
The technically this is easy legally this is easy since nitendo just licensed the ARM ISA (the publishers would have to publish through a new medium but that's simple enough)
the problem is the screen
Battery life on phones has to be quite long
LCD are the single greatest drain on a battery to put in a screen of the GBA's resolution would mean the battery life of in use would decrease considerably
sad really

john jones
p.s. how long to EPOC GBA emulator is seen I wonder (-;
fractals are good for storeing large amounts of information but decompression is hard and how do you then represent the information useing standard methods or volumetric pixels type approach ?
seems nice but I would like more details before makeing any jugment
anyone have details ?

john jones
p.s. I am sure a game used this type of thing before
I hope that they can keep up and dont go burning CD until they are ordered (JIT inventry)
I think they should screen print some CD with just their logo on it (no version numbers so they can use it for whatever) so that it would look pro as well
throw in a book on unix programing and hey presto a Real product !
On2 technologies have released their VP3 video codec to the open source

so it looks up its just putting a box togther that runs them which would not be all that hard if your box ran uclinux or plain linux (no porting involved yey)

simple get a psion 7 it runs on a strongARM two AA batterys are all thats required to run a strongARM lets see ANY x86 CPU do that !
(yes I know psion recently gave up selling to the public but still sell bundles for corp's and will do so for a long time)
MOT CPU's dont do bad(witness the raves about ibook) but really ARM and MIPS are the way to go
(oh and get a small LCD as these tend to eat POWER for breakfast, lunch and tea)
so have a look at CE powered devices that can be turned into linux/BSD machines or just stick to what it came with

its all software its just a standard ARM7 no custom graphics chip
you may use nintendo's custom bliting Libs but you dont have to
there is NO custom chip just a bios that does the Z80 emulation
timeing is just a matter of throttling the CPU speed to be the same as the GBA
the LCD controller as far as I am aware is just stock ARM IP
they did this because they had such a nightmare with the colour Game Boy and such
lesson : do things in software and keep the hardware standard
yes you might have to change things in a game to use non nintendo stuff but its not all that hard

the problem is that most reporters use combi sat /POTS/ISDN and they hate technology
because it has to work anywhere say even on a rock outside kabul (sat)
that limits the bandwidth to 33.6 now you can do really well with open source codecs on 33.6
just recently :
On2 open source the VP3 video codec
On2 technologies have released their VP3 video codec to the open source
