and yes something like that was our original plan.... except that the machine room was heavily airconditioned and we didn't want to trash our mainframe (this was back in the day when memory cost ~$1M/megabyte)
Many years ago I found myself in a turf war with the 'operators' who looked after our mainframe.... in their view system programmers weren't allowed to touch the hardware... anyway as a response we instituted a physical penetration analysis of the machine room.... the number of different ways in we found was in the mid teens - some involved children (or small adults) climbing thru ducts or thru the windows we gave people their printouts through, others involved finding ways in under the false floor (there were several) - but the one that took the cake was when we noticed that all the hinges on each and every door to the room was on the outside... anyone could show up at any time and steal the doors
printf's perfectly OK so long as you understand what's going on (and you better if you're doing something like this) - if you're doing real-time multithreaded stuff you have to be aware of the consequences of the hidden mutexes inside stdio (and malloc/new!) and what they can do (serialisation, priority inversion). If you do have issues with printf in a real-time system (more to do with the TIME it takes to send them to the console) you can build a silo do drop them into and print them later.
However more to the point - you shouldn't be debugging a 'big asynchronous system' from scratch - build it in little bits and test them as you go
but you don't go far enough - to those of us from parliamentary democracies the US system smells of corruption - the very idea of non-elected political appointees is just wrong. Certainly cabinet ministers (heads of government departments) should be appointed - but elsewhere they are elected MPs from the governing party. But appointing 100s (1000s?) of people each time is quite insane and results in things like this (or in our case some bozo travel agent as ambassador simply because they raised a lot of money for Bush)
but you're assuming that the only valid TCP packets are access to web servers - but tcp/udp are only different ways to get bits around - I vpn into work to get my day to day work done - it's none of my ISP's business what's inside that tunnel.
In the end we pay our ISPs to move bits around for us - their job is to move data from one IP address to another - what protocols we run under IP is none of their business - someone upthread complained that BT uses too many router resources - it wouldn't if they weren't peeking into out IP packets - of course part of this problem is that we (or rather they) are running out of IP addresses and have to NAT everything (roll on IPV6) - NAT only works because it knows about the internal ports in UDP/TCP - heaven help you if you want to use or design your own IP carried protocol, in that sense the internet as we currently have it is broken at a quite basic level - it means we're stuck with UDP/TCP
can't agree more - my prius will drag just about anyone from a standing start, especially on a hill - it's that high torque electric motor that does it - instant power you just don't get from an gas engine without trashing your clutch
Not being party to the inside of what's going on we can;t tell whether it's a chicken or an egg... but my guess is that either: it's a reaction, a bargaining chip, to the US telcos recent round of attempts to set up a toll road... or the telcos are reacting to rumours of what google are doing.
Then again it might all be just a way for them to tie all their disparate data centers (they have them all over the world) more reliably
I think the contents are encrypted and can't be accessed unless you present the printed key (can't be accessed directly by the trash-can bomb as you walk down the street - so it can't tell what your nationality is, maybe just that you have an e-passport [and maybe as a result that you are a westerner]). But once unlocked the data is transfered in the clear.
So we probably asked slightly different things (as I understand there is a possibility of snooping at the reading station which is supposed to be shielded, and it's not an environment where the guy behind you in the line has the chance to set up a carefully aligned antenna to snoop anyway).
On the other hand I did ask the guy explicitly "will the NZ e-passport have an embedded RF shield in the cover as apparently the US one will?" and got a simple answer "no".
I have 8 years left on my current one.... I bet it gets recalled before then
Yes you are less of a target if you're not connected all the time - but why not just unplug the computer when you're not using it? same difference - or get a good firewall - having lower bandwidth doesn't stop intrusions at all, it just means that more of the bandwidth you want to use is being tied up by them - higher bandwith means there's all the more for you (I guess what I want is a firewall that I control at the ISP end of the wire)
yes of course - but kids don't learn linearly - "this is wrong because you won't learn as much" isn't enough, you have to put that message in with such more practical things - - it's kind of like "stealing is wrong" isn't enough, "you'll get caught" isn't even as good as what's maybe the equivalent: "see those black half-globes up there, they have cameras in them and they're watching you"
with both my kids around about age 9-10 I discovered some paper they were going to hand in that was copied from the web.... sat them down, typed 3 words of vocab that so obviously wasn't written by them into google and lo and behold the web page they copied it from.... long discusion ensued - about how to write a paper, paraphrase a source (or quote it correctly) and an explanation about how their teachers could do the google trick just as well as I could
It's a great age to learn this - probably Jr High teachers should do that demo to each new incoming class - "I can catch you out - it's this easy"
That's what happens here (New Zealand) - we typically use 'swedish rounding' - we got rid of 1c/2c coins a while back and they're in the process of removing the 5c coin - our smallest will be 10c (about 7c US). It helps that our salestax is always included in the quoted price of an item - and when you go to the supermarket the rounding is only applied to the total price of what you buy
It's actually worse than this - by requiring NZ to issue e-passports - the US is forcing EVERY NZer who gets a passport to get one whether they are travelling to the US or not - at $150 a pop it's a tax (used to be half that) the US is in essence applying to all of us who want to travel. I know most USAians don't have passports and don't travel much, but the rest of us like to and do it a lot
After the NZ govt announced the new E-passports I had an email exchange with one of the people involved with this process, he indicated:
data IS encrypted using a printed machine readable key on the passport page
it wont have an embedded woven shirld in the cover like the US ones do
the polycarbonate page the chip is embedded in will make the passport much less flexible (I carry mine everywhere and depend on it sitting comfortably in a jacket pocket or occasionally seat pocket of my jeans) - I still worry I'll hear a 'snap'
luckily I still have 9 years on my current one - hopefully long enough for them to get the bugs out...
but that's what Coverity does for a living - I assume that what's really going on here is that DHS is paying someone to run Coverity over stuff (people who already have access to it at work probably ought to be feeding any spare code that's lying around through it anyway - with your boss's permission of course)
actually I think they're over reaching themselves, at least in so far as storage manufacturers are concerned - I've just skimmed the claims on the 3 patents and they all refer to the creation of directory entries (more importantly directory entries longer than 11 characters) - I'm sure blank preformatted media doesn't need this, moreover a smart camera manufacturer probably can keep their file names inside the old 8.3 restriction - hopefully the camera/media manufacturers will band together and stick it to M$
actually that's a great point and I bet one of two things will happen:
all cards/sticks/what have you come blank and get formatted by your camera/etc (where you'll pay the 25c)
M$ will sue to get all the media vendors to add 25c to their costs and some non-windows user will counter-sue because M$ is leveraging their monopoly
I bet for the first because M$ will tread warily around the second.
On the other hand the world is probably ready for a simple public domain file system that's unencumbered by patents or copyright. FAT's one saving grace is that it's simple and easy to implement, for most of these applications performance isn't a big deal, simplicity and robustness is much more important.
Lucky you - I have the opposite problem - I enabled it when I lived in California, now I've moved to New Zealand and Vonage wont disable it no matter what I do.....

The +1 for living in the G8 is pretty bogus too (or is it a clue?)
