I've barbequeued prawns before, the result is not worth the expense. I have no idea how prawns are meant to be cooked, but barbequeueing em just made black, crispy, carcinogenous prawns that tasted like arse.
You probably left the prawns on the barbecue for too long. Depending on size it takes from about thirty seconds up to a couple of minutes to barbecue prawns. Experiment a bit more and you'll find out how to do it.
The other possible reason is that your barbecue was more like a blazing campfire than a proper barbecue. In that case nothing you put in it will be edible not to mention tasty.
Hmm, during the seven years I used Psions (one 3a and two 5mx'es, all gone now due to hardware failures) I did a soft reset twice - and I had to look it up in the manual how to do it on both occasions.
I've had a Pocket PC PDA for about half a year now. On the average I do a soft reset daily...
Visionary programmers figured out how to share music on the internet,American reactionary media industries sought to counter it. Visionary companies figured out how to make money from free software, American reactionaries are trying to impose the DMCA. Visionary students in the the US now consider it the norm to freely share music, American reactionaries are suing for billions.
Seems to me the Americans have their share of reactionaries...
Actually, when my first 5mx died in February, I got a new one (well, a second hand one since they are no longer in production..) ASAP, loaded the backup (damn, three weeks old! That'll teach me!) and was up and running again within a couple of days.
I don't have any of the problems you mention. The Psion runs for about a month on two AA batteries. It is my only calendar and contacts database so I don't synch it with a PC. And once software is installed on it, that software tends to just work.
But eventually it will give out of course. I just hope that someone launches a decent PDA before then.
Rather than mandating one type of service *cough*GSM Europe*cough*, they're letting all the standards duke it out.
And in the meantime we here in Europe have 90% cell phone coverage because of our single standard. This provides a level ground for competition between the service providers and hence the competition among them is fierce. This means lower prices for the service not to mention the cell phones. Here in Denmark, service providers have sold cell phones for 1 DKR (roughly 13 cents) in order to get new customers. Furthermore, rates are so low that in some cases they can compete with landline phones.
Eventually, the best service will win out.
No, because there is no true competition on the US market. Customer lock-in makes it so expensive to switch that most coustmers are loathe to do so thus virtually eliminating competition between the service providers.
The free market has nothing to do with GSM adoption. It was imposed by various European telecom agencies.
No. Having one single system actually created the free market. My service provider knows that if I'm dissatisfied with their service, I can switch to another provider - and I can even take my phone number with me. So the competition between service providers is fierce indeed.
In Europe, no-one cares about the underlying technology. That would be like worrying about the TCP protocol when reading Slashdot.
In a known environment it becomes trivial. All you need to know are 1. indexes, and 2. tables sizes. There is a whole volume of information on ordering the clasues of a SQL query based on these criteria (and the type of clause itself) that will get you an optimal query without any use of profilers and crap.
That knowledge is the leaky abstraction. Joel's point is that SQL tries to make an abstraction where this knowledge shouldn't be necessary - yet it is.
Yes, the EPOC OS is a true pre-emptive multi-tasking OS. It is also the basis of Symbian. That being said, I've yet to see an aplication that is not full-screen. But it is perfectly possible (as in: I have done this) to fetch email while editing a document or a spreadsheet or such. I should add that I at the same time have numerous other apps open in the background. Right now I have about ten open apps, including the tomtom CityMaps map over Copenhagen. Memory usage is 6312K or about 38%.
However, one thing I do like is that the phone and the palm can both run at the same time...
I am not quite convinced myself that a phone/PDA combo is what I want. Taking notes while talking is not the problem; just use a headset (Bluetooth rules!!). But there are times where I don't like the (comparative) bulk of the PDA. What I'd really like is for my PDA and phone to be able to synchronize contacts and calendar, preferably via Bluetooth. My phone (an Ericsson R520m) can do this but I've yet to find a PDA that supports SyncML on Bluetooth.
With the PPC its very very easy not to close applications. What happens? The system slows down to a crawl as it tried to run 5 or 6 different applications. Again, this is the user being in control of the computer. I want the ability to close applications when I'm not using them. That is my decision, not the computers.
If the PPC didn't slow down when the number of applications grew, you wouldn't even think about closing those other apps.
So it is not you who decides which applications that should be open - the PPC does. If you want to use the PPC efficiently, you must close some of the other applications, i.e. the PPC forces your decision about closing applications.
A PDA is much easier to use if you don't have to think about how many apps are open or not. And no, this is not a pipe dream. The Psion 5mx that I use daily, has no noticeable slowdown even if I have 10 or 15 open applications.
and then, after modifying XP to actually do the stuff they need, they use 100 copies of it, and they have to pay Microsoft for 100 licenses of XP. Wouldn't this work?
That's the way it's usually done in the embedded world.
It pays for the licensor to drag things out to play hardball and backtrack on terms that you had agreed to.
Up to a certain point - as Sendo has so amply demonstrated. I don't think this is the outcome Microsoft wanted.

while IBM (which did the primary -- Rockwell got the backup) went with their fancy-schmanzy preemptive system, which I believe was blamed for scrubbing a Shuttle launch early in the program.
Ahem, that's not quite how it happened...
The cause of the crash, you refer to, was that all the processors read a single hardware clock during start-up. Usually they all read the same value but since hardware restrictions required the processors to read the clock one at a time, it could happen that the clock ticked between reads. This happened very seldom, in fact later investigation revealed that it had happened only once during testing.
The actual crash occured much later when the flight-control computers compared their internal clocks and found out that they were different.
At the time everybody were completely baffled and it took several months of investigation to find out what had really happened. But as you can see from this description, the complexity of the RTOS was not the culprit - this time:-)
BTW, I read this in an ACM publication. I've tried to find a link but haven't succeeded so far.
Because SPAM has a marginal cost of $0, to both sender and receiver.
I beg to differ...
It doesn't REALLY cost anyone anything more that you're sending 100,000 pieces of mail versus 1000 to a campus-wide discussion group, EXCEPT for the time that the 100,000 people receiving it must spend deleting the mail.
Your time may be free but most people's time isn't. Lets (rather arbitrarily) set the hourly rate at $30. If it takes 10 seconds to take care of a spam mail (update blocking list and filters, delete the mail), 100,000 spam mails will cost around $8.300 in lost time. And that is for just one (1) spam mail.
No, it won't cost each person very much but collectively, the cost is significant - especially when you take into account that most people get several spam mails every day and that 100,000 pieces of a single spam mail is rather on the low side.
I actually know a guy who does just that. Not for a living though, as he has been unable to find a job where they will let him use his favourite 8086-assembler. And before you ask, it's not because all of us who know anything about programming haven't told him that he is up a dead end.
However, with the the maturity of operating systems, many of them now include device drivers, APIs, objects and other goodies that insulate the average programmer from the hassle of issues like latency.
While mature OS'es are indeed very nice to have, they are not universally available. Mature OS == larger code size == larger HW demands == uses more power == larger battery == heavier equipment. And yes, this is still a very real issue. You are not always in a situation where you can throw more hardware at the problem.
As for latency, there are situations where you need absolute control over the timing. I recently participated in the development of a portable heart defibrillator. If there is a delay between the order to give a shock and the actual delivery of that shock, you may kill the patient instead of reviving him. For such jobs, you need guarantees, not promises.
So yes, I'd say thee is definitely a need for this book.
You're quite the subversive, aren't you? You didn't even mention that this phone runs Linux!
This really should be modded "Funny"...
Read the article again. It is the new cordless Screen Phone HS210 that runs Linux. I'd be very surprised if the 230 or the 260 is running Linux. It would be vast overkill for the functionality they have.
Fail to win a licence and the stock market would kill you quickly, win one and your own debts would kill you slowly. They all opted for the slow death hoping that they had bought enough time to figure something out.
Not necessarily. When the UTMS licenses were autioned off in Denmark there were five bidders for four licenses. The telco that didn't get a license is now in very good position because the four others are so deeply in debt that a partner (especially one with a large current customer base) would be very welcome indeed.
I have had a couple of Ericsson 260 cordless DECT phones with NiMH batteries for a couple of years. They work very well and have no problems with memory effect (unlike our previous cordless with NiCads).

NTSC pre-dates PAL by a couple of years. By the time PAL was developed, NTSC was firmly entrenched in the US.
U.S. - uses the English system of measure whereas the rest of the world uses the more intuitive metric system
The English system pre-dates the metric system ;-) but I do agree that the metric system makes more sense.
U.S. - drives on the wrong damn side of the road
What? Have they switched? Last time I looked they drove on the right side of the road.

A doctor, a civil engineer and a programmer are discussing whose profession is the oldest.
"Surely medicine is the oldest profession." says the doctor. "God took a rib from Adam and created Eve and if this isn't medicine I'll be..."
But the civil engineer breaks in:
"But before that He created the heavens and the earth from chaos. Now that's civil engineering to me."
The programmer thinks a bit and then says:
"And who do you think created chaos?"
Such as RTEMS?
Depends...
With a GPRS-phone it actually works quite well. I use it several times a week.
I don't have any of the problems you mention. The Psion runs for about a month on two AA batteries. It is my only calendar and contacts database so I don't synch it with a PC. And once software is installed on it, that software tends to just work.
